PARTICULAR EMBODIMENTS

[0057] The utility model will be further described in detail below with reference to the embodiments of the drawings.

Embodiment 1

[0058] As shown in FIG. 1 to FIG. 7, a flame simulating device includes a mist generating chamber 1, atomizing heads 2, an air orifice 3 and a nozzle 4. The flame simulating device further includes a light source 5 and a transparent cover 42. The nozzle 4 is elongated in the longitudinal direction and is defined by nozzle walls 41 with Coanda curved surface shapes on both sides. The Coanda surface in this embodiment is an arc-shaped curved surface. The minimum dimension B of the nozzle walls 41 on both sides of the cross section of the nozzle 4 is preferably 2 mm to 20 mm, and the dimension shown in this embodiment is about 5 mm. The air orifice 3 is disposed below the nozzle 4. In this embodiment, the dimension of the air orifice 4 in the longitudinal direction is slightly longer than the length dimension of the nozzle 4, and the air orifice 3 is defined by air orifice walls 31 on both sides. The cross-sectional shape of the air orifice 3 is a flared, triangular or trapezoidal shape with a gentle and smooth transition, and the top of the air orifice 3 is constricted into an air nozzle 32. The width dimension A of the air nozzle 32 at the cross section of the air orifice 3 is preferably 0.5 mm to 6 mm and is about 2 mm in this embodiment as shown. The inner surfaces of the air orifice walls 31 and the nozzle walls 41 are all smooth surfaces. In Embodiment 1, the mist generating chamber 1 is symmetrically disposed on both sides of the air orifice, and the mist generating chamber 1 is defined by a region surrounded by the mist generating chamber housing 11. The mist generating chamber 1 is provided with a mist outlet 12 along the longitudinal direction of the nozzle 4, and the mist outlet 12 communicates with the nozzle 4. The mist outlet 12 is defined by a region between the air orifice walls 31 and the mist generating chamber housing 11, and the air flow provided by the air nozzle 32 is blown upward to flow along the direction of the mist outlet 12 and into an inlet end of the nozzle 4. The atomizing head 2 is an atomizing head made by the principle of ultrasonic oscillation, and the atomizing heads 2 are symmetrically arranged on both sides of the mist generating chamber 1 along the longitudinal direction. In this embodiment, both sides of the mist generating chamber 1 are respectively provided with three atomizing heads 2, so that the generated mist is more uniform along the longitudinal direction. The atomizing nozzle of the atomizing head 2 is provided with an energy gathering cover 21. A liquid is further provided in the mist generating chamber 1, and in Embodiment 1, the liquid is water. The liquid level is a certain height over the atomizing head 2 but may be a certain distance below or above the outlet of the energy gathering cover 21. Inside the mist generating chamber 1, a water retaining plate 15 is further disposed before the mist outlet 12. The light source 5 is disposed obliquely below the nozzle 4. In Embodiment 1, the light source 5 is disposed only on one side of the nozzle 4, the light emitted by the light source 5 irradiates upward on the outlet of the nozzle 4 and thereabove, and at least the nozzle wall 41 adjacent to one side of the light source 5 is made of a transparent material. The transparent cover 42 is disposed on the nozzle wall 41 on the side adjacent to the light source 5 and seals the opening region between the upper end outlet of the nozzle 4 and the outer casing 7, and in this embodiment, the transparent cover 42 and the nozzle wall are integrated. An air duct 6 is further disposed below the air orifice 3, and the air duct 6 is also elongated and is disposed along the longitudinal direction of the air orifice 3. The air duct 6 provides a guiding air flow blown upward to the air orifice 3 by a fan 61. A plurality of fans 61 may be disposed according to the length dimension, and there are two fans 61 in this embodiment. The inside of the air duct 6 is further provided with a spoiler 62, and the disturbance of the spoiler 62 may cause the air force provided by the fan 61 to be more uniformly distributed in the air duct 6 along the longitudinal direction. The inside of the air duct 6 is further provided with a heating element 63, and the heating element 63 is mounted on a side of the spoiler 62 facing the fan 61. The heating element 63 can heat the guiding air flow provided by the fan 61, so that the air with air force in the air duct is hot air.

[0059] During operation, the atomizing head 2 is energized to atomize the liquid, and the mist is collected above the liquid level of the mist generating chamber 1. The fan 61 is energized to generate an air force, and the air force is subjected to the action of the spoiler 62 to be uniformly blown into the air duct 6 along the longitudinal direction, thereby entering the air orifice 3. The cross-sectional shape of the air orifice 3 is a flared, triangular or trapezoidal shape that is constricted with a gentle and smooth transition, and thus, has a further converging and guiding effect on the air flow in the air duct 6, and the air flow is blown {02458125.1} 20 out from the air nozzle 32 uniformly and vertically upward in the longitudinal direction. Since the heating element 63 heats the air in the air duct 6, the air blown into the air orifice 3 is hot air, and the air blown out from the air nozzle 32 is also hot air. Since the nozzle 4 is disposed above the air nozzle 32, the hot air blown from the air nozzle 32 directly enters the lower end inlet of the nozzle 4. In the mist generating chamber 1, in the region adjacent to the mist outlet 12, due to the flow of the air blown from the air nozzle 32, a low pressure is formed in this region, and the outlet of the air nozzle 32 provides an air flow along the direction of the mist outlet 12. Under the Venturi effect, the air flow blown by the air nozzle 32 has an adsorption effect on the mist outlet 12, so that the mist in the mist generating chamber 1 is attracted to flow to this region through the mist outlet 12, and the mist from the mist outlet 12 and the guiding air flow from the air nozzle 32 form an air-mist mixture to enter the lower end inlet of the nozzle 4 together. Since the nozzle walls 41 on both sides of the nozzle 4 are set as the Coanda surfaces, according to the principle of the Coanda Effect (also referred to as the wall-attachment effect), as long as the curvature is not large, the fluid will flow along the surface of the object, that is, away from the original flow direction, but flow along the surface of the convex object. It can be known that the air-mist mixture entering the inlet end of the nozzle 4 will flow along the surface of the nozzle wall 41, thereby the air-mist mixture is expanded, and slowly flutters upward out of the upper end outlet of the nozzle 4. Since the air-mist mixture has a certain amount of heat and is hotter than the surrounding space, according to the thermodynamic principle, the air-mist mixture has the power to continue to flutter upward under the thermodynamic effect, so that the air-mist mixture flutters higher. The light source 5 disposed obliquely below the nozzle 4 is energized to emit light irradiating upward, and since at least the nozzle wall 41 adjacent to one side of the nozzle 4 and the transparent cover 42 are made of a transparent material, the light emitted by the light source 5 can penetrate the nozzle wall 41 and the transparent cover 42, irradiate on the upper end outlet of the nozzle 4 and thereabove, and then continue to irradiate on the air-mist mixture slowly fluttering out from the upper end outlet of the nozzle 4. During the upward fluttering of the air-mist mixture, various ascending shapes are formed, and under the action of the light irradiation, an effect similar to the shapes of leaping flames is created, thereby simulating the flame combustion state. Since the nozzle 4 is elongated, a burning flame in the longitudinal direction is formed. The light emitted by the light source 5 may be monochromatic, preferably yellow or amber, or may be polychromatic.

[0060] Since the transparent cover 42 seals a region between the opening on the outer casing 7 and the nozzle 4, the mist fluttering out of the nozzle 4 cannot enter the inside of the flame simulating device, thereby protecting the electrical elements inside the flame simulating device. Since the mist in the mist generating chamber 1 flows toward the mist outlet 12, the air pressure in the entire mist generating chamber 1 is lowered. Therefore, a breathing port 13 is disposed in a place where the mist generating chamber 1 is away from the mist outlet 12, and the breathing port 13 is also disposed along the longitudinal direction of the mist generating chamber 1. The inside of the mist generating chamber 1 communicates with the atmosphere through the breathing port 13, and the inside of the entire mist generating chamber 1 can maintain the same air pressure as the surrounding atmosphere. In order to make the mist in the mist generating chamber 1 possibly flow back and emerge from the breathing port 13 when a region with a sufficiently-low pressure is not formed in the region near the mist outlet 12 and the inside of the mist generating chamber 1 does not have a sufficient air flow to flow to the mist outlet 12, a foamed cotton 14 is disposed in the breathing port 13. The foamed cotton 14 is made of a porous material having a plurality of pores which allow air to pass through but prevents the passing of fine water droplets of mist.

In Embodiment 2, compared with Embodiment 1, the mist generating chamber 1 is arranged on a single side with respect to the air orifice 3 and the nozzle 4, and the light source 5 is arranged on the other side with respect to the mist generating chamber 1.

[0062] The mist generating chamber 1 is disposed only on one side of the air orifice 3, thereby saving the space, facilitating mounting and increasing the volume of the liquid storage tank 8.

Embodiment 3

[0063] As shown in FIG. 10 to FIG. 18, an atomizing simulation fireplace includes a mist generating chamber 1, atomizing heads 2, an air orifice 3, a nozzle 4, a light source 5, an outer casing 7 and a simulated fuel bed 9. The nozzle 4 is elongated in the longitudinal direction and is defined by nozzle walls 41 with Coanda curved surface shapes on both sides. The Coanda surface in this embodiment is an arc-shaped curved surface. The minimum dimension B of the nozzle walls 41 on both sides of the cross section of the nozzle 4 is preferably 2 mm to 20 mm, and the dimension shown in this embodiment is about 5 mm. The air orifice 3 is disposed below the nozzle 4. In this embodiment, the dimension of the air orifice 4 in the longitudinal direction is slightly longer than the length dimension of the nozzle 4, and the air orifice 3 is defined by air orifice walls 31 on both sides. The cross-sectional shape of the air orifice 3 is a flared shape with a gentle and smooth transition, and the top of the air orifice 3 is constricted into an air nozzle 32. The width dimension A of the air nozzle 32 at the cross section of the air orifice 3 is preferably 0.5 mm to 6 mm and is about 2 mm in this embodiment as shown. The inner surfaces of the air orifice walls 31 and the nozzle walls 41 are all smooth surfaces. In this embodiment, the mist generating chamber 1 is symmetrically disposed on both sides of the air orifice, and the mist generating chamber 1 is defined by a region surrounded by the mist generating chamber housing 11. The mist generating chamber 1 is provided with a mist outlet 12 along the longitudinal direction of the nozzle 4, and the mist outlet 12 communicates with the nozzle 4. The mist outlet 12 is defined by a region between the air orifice walls 31 and the mist generating chamber housing 11, and the air flow provided by the air nozzle 32 is blown upward into an inlet end of the nozzle 4 along the mist outlet 12. The atomizing head 2 is an atomizing head made by the principle of ultrasonic oscillation, and the atomizing heads 2 are symmetrically arranged on both sides of the mist generating chamber 1 along the longitudinal direction. In this embodiment, both sides of the mist generating chamber 1 are respectively provided with three atomizing heads 2, so that the generated mist is more uniform along the longitudinal direction. The atomizing nozzle of the atomizing head 2 is provided with an energy gathering cover 21. A liquid is further disposed in the mist generating chamber 1, and in Embodiment 1, the liquid is water. The liquid is at a certain height above the atomizing head 2 but may be a certain distance below or above the outlet of the energy gathering cover 21. Inside the mist generating chamber 1, a water retaining plate 15 is further disposed before the mist outlet 12. The light source 5 is disposed right below or obliquely below the nozzle 4, or on one side or both sides, and the light emitted by the light source 5 may be monochromatic, preferably yellow or amber, or may be polychromatic. At least the nozzle wall 41 adjacent to one side of the light source 5 is made of a transparent material. The transparent cover 42 is disposed on the nozzle wall 41 on the side adjacent to the light source 5 and seals the opening region between the upper end outlet of the nozzle 4 and the outer casing 7, and in this embodiment, the transparent cover 42 and the nozzle wall are integrated.

[0064] The mist generating chamber 1, the atomizing heads 2, the air orifice 3, the nozzle 4 and the light source 5 are all disposed inside the outer casing 7, and the outlet of the nozzle 4 communicates with the outside of the upper surface of the outer casing 7. In this embodiment, the simulated fuel bed 9 is composed of an ash bed 91 and a simulated solid fuel 92 and is disposed on the upper surface of the outer casing 7. The ash bed 91 is provided with a flame outlet 911 in the longitudinal direction corresponding to the outlet position of the nozzle 4. The simulated solid fuel 92 is placed over the ash bed 91 in a cross manner. The light emitted from the light source 5 can irradiate on the outlet of the flame outlet 911 and thereabove. Both the ash bed 91 and the simulated solid fuel 92 are made of a translucent material. An ash bed light source 912 is disposed inside the ash bed, and a simulated solid fuel light source 921 is disposed inside the simulated solid fuel 92. The ash bed light source 912 can make the ash bed 91 to be self-luminous to simulate the state of residual fire combustion of ash, and the simulated solid fuel 921 can make the simulated solid fuel 92 to be self-luminous to simulate the state of real solid fuel combustion.

[0065] An air duct 6 is further disposed below of air orifice 3, and the air duct 6 is also elongated and is disposed along the longitudinal direction of the air orifice 3. The air duct 6 provides a guiding air flow blown upward to the air orifice 3 by a fan 61. A plurality of fans 61 may be disposed according to the length dimension, and there are two fans 61 in this embodiment. The inside of the air duct 6 is further provided with a spoiler 62, and the disturbance of the spoiler 62 may cause the air force provided by the fan 61 to be more uniformly distributed in the air duct 6 along the longitudinal direction. The inside of the air duct 6 is further provided with a heating element 63, and the heating element 63 is mounted on a side of the spoiler 62 facing the fan 61. The heating element 63 can heat the guiding air flow provided by the fan 61, so that the air with air force in the air duct 6 is hot air.

[0066] A liquid level gauge 10 is further disposed in the mist generating chamber 1 for detecting whether the liquid level in the mist generating chamber 1 is within the liquid level range required for the operation of the atomizing head 2. A liquid storage tank 8 is provided near the mist generating chamber 1 for storing the standby liquid supplied to the mist generating chamber 1. Preferably, in Embodiment 1, the lowest water level of the liquid storage tank 8 is higher than the highest water level allowed by the mist generating chamber 1.

[0067] During operation, the atomizing head 2 is energized to atomize the liquid, and the mist is collected above the liquid level of the mist generating chamber 1. The fan 61 is energized to generate an air force, and the air force is subjected to the action of the spoiler 62 to be uniformly blown into the air duct 6 along the longitudinal direction, thereby entering the air orifice 3. The cross-sectional shape of the air orifice 3 is a flared constricted shape with a gentle and smooth transition, and thus, has a further converging and guiding effect on the air flow in the air duct 6, and the air flow is blown out from the air nozzle 32 uniformly and vertically upward in the longitudinal direction. Since the heating element 63 heats the air in the air duct 6, the air blown into the air orifice 3 is hot air, and the air blown out from the air nozzle 32 is also hot air. Since the nozzle 4 is disposed above the air nozzle 32, the hot air blown from the air nozzle 32 directly enters the lower end inlet of the nozzle 4. In the mist generating chamber 1, in the region adjacent to the mist outlet 12, due to the flow of the air blown from the air nozzle 32, a low pressure is formed in this region, and the outlet of the air nozzle 32 provides an air flow moving along the direction of the mist outlet 12. Under to the Venturi effect, the air flow blown by the air nozzle 32 has an adsorption effect on the mist outlet 12, so that the mist in the mist generating chamber 1 is attracted to flow to this region through the mist outlet 12, and the mist from the mist outlet 12 and the guiding air flow from the air nozzle 32 form an air-mist mixture to enter the lower end inlet of the nozzle 4 together. Since the nozzle walls 41 on both sides of the nozzle 4 are set as the Coanda surfaces, according to the principle of the Coanda Effect (also referred to as the wall-attachment effect), as long as the curvature is not large, the fluid will flow along the surface of the object, that is, away from the original flow direction, but flow along the surface of the convex object. It can be known that the air-mist mixture entering the inlet end of the nozzle 4 will flow along the surface of the nozzle wall 41, thereby the air-mist mixture is expanded, and gradually flutters upward out of the upper end outlet of the nozzle 4. Since the air-mist mixture has a certain amount of heat and is hotter than the surrounding space, according to the thermodynamic principle, the air-mist mixture continues to flutter upward under the thermodynamic effect, and then flutters upward from the gap of the simulated solid fuel 92 through the flame outlet 911. The light source 5 disposed obliquely below the nozzle 4 is energized to emit light irradiating upward, and since at least the nozzle wall 41 adjacent to one side of the nozzle 4 and the transparent cover are made of a transparent material, the light emitted by the light source 5 can penetrate the nozzle wall 41 and the transparent cover, irradiate on the outlet of the flame outlet 911 and thereabove, and then irradiate on the slowly fluttering air-mist mixture. During the upward fluttering of the air-mist mixture, various ascending shapes are formed, and under the action of the light irradiation, an effect similar to the shapes of burning and leaping flames is created around the simulated solid fuel 92 and/or above the ash bed 91, thereby simulating the flame combustion state. Since the nozzle 4 is elongated, a burning flame in the longitudinal direction is formed. The light emitted by the light source 5 may be monochromatic, preferably yellow or amber, or may be polychromatic.

[0068] While the light emitted from the light source 5 irradiates on the mist to form the effect of burning and fluttering flame on the simulated fuel bed 9, the ash bed light source 712 inside the ash bed 91 emits light to enable the ash bed 91 to simulate the state of residual fire combustion of ash., and the simulated solid fuel light source 921 inside the simulated solid fuel 92 emits light to enable the simulated solid fuel 92 to simulate the state of real solid fuel combustion, so that the ash bed 91 and the simulated solid fuel 92 complement the mist simulated flame to jointly form the state of flame simulating the real fuel combustion.

[0069] Since the transparent cover 42 seals a region between the opening on the outer casing 7 and the nozzle 4, the mist fluttering out of the nozzle 4 cannot enter the inside of the flame simulating device, thereby protecting the electrical elements inside the flame simulating device.

[0070] Since the mist in the mist generating chamber 1 flows toward the mist outlet 12, the air pressure in the entire mist generating chamber 1 is lowered. Therefore, a breathing port 13 is disposed in a place where the mist generating chamber 1 is away from the mist outlet 12, and the breathing port 13 is also disposed along the longitudinal direction of the mist generating chamber 1. The inside of the mist generating chamber 1 communicates with the atmosphere through the breathing port 13, so that the inside of the entire mist generating chamber 1 can maintain the same air pressure as the surrounding atmosphere. In order to make the mist in the mist generating chamber 1 possibly flow back and emerge from the breathing port 13 when a region with a sufficiently-low pressure is not formed in the region near the mist outlet 12 and the inside of the mist generating chamber 1 does not have a sufficient air flow to flow to the mist outlet 12, a foamed cotton 14 is disposed in the breathing port 13. The foamed cotton 14 is made of a porous material having a plurality of pores which allow air to pass through but prevents the passing of fine water droplets of mist.

[0071] As shown in FIG. 19 to FIG. 20, an atomizing simulation fireplace includes a mist generating chamber 1, atomizing heads 2, an air orifice 3, a nozzle 4, a light source 5, an outer casing 7 and a simulated fuel bed 9. Compared with Embodiment 3, the mist generating chamber 1 is arranged on a single side with respect to the air orifice 3 and the nozzle 4, the light source 5 is arranged on both sides of the nozzle 4, and the atomizing heads 2 are also arranged on a single side and arranged in plurality along the longitudinal direction. The mist generating chamber 1 is disposed only on one side of the air orifice 3, thereby saving the space and increasing the volume of the liquid storage tank 8, so that the working time of the fireplace can be longer.

[0072] In addition, the simulated fuel bed 9 is composed of an ash bed 91 and pebbles 93. The pebbles 93 are scattered casually on the ash bed 91. After fluttering out of the flame outlet 911, the air-mist mixture simulates the shape of the flame above the pebbles 93.

[0073] A liquid storage tank liquid level gauge 81 is disposed in the liquid storage tank 8. The liquid storage tank liquid level gauge 81 monitors the liquid level change in the liquid storage tank 8, so that the user can be promptly reminded to add the liquid used for atomization.

Embodiment 5

[0074] As shown in FIG. 21 to FIG. 23, a atomizing simulation fireplace further includes a fireplace cabinet 20 and a decorative frame 30 on the basis of Embodiment 3. The atomizing simulation fireplace of Embodiment 1 is integrally disposed on the lower side inside the fireplace cabinet 20. The decorative frame 30 is disposed outside the front surface of the fireplace cabinet 20 to increase the overall ornamental value of the atomizing simulation fireplace.

[0075] The top of the fireplace cabinet 20 is further provided with a heated air orifice device 201. The heated air orifice device 201 can blow hot air to the front surface of the fireplace cabinet 20, so that the atomizing simulation fireplace has a heating function while having an ornamental effect of flame. The air inlet of the heated air orifice device 201 faces the flame outlet 911. Since the heated air orifice device 201 forms a suction force when air enters and thus has a further upward driving effect on the mist fluttering out of the flame outlet 911 to further increase the height of the mist simulated flame.

[0076] The above description is only preferred embodiments of the utility model. It should be noted that those skilled in the art may also make improvements and modifications without departing from the technical principles of the utility model, and such improvements and modifications should also be considered to be within the protection scope of the present invention.
