(12) As people's material life become wealthy, their pursuit of spirituality is growing day by day. Stoves are normally used for heating people or objects. In addition to that, people are more concerned about their value as a new ornamental object. At present, there have appeared many kinds of decorative stoves. For example, some stoves adopt volcanic stone, broken glass and others as the stove media to make the burning state of the flowing gas closer to the natural flame by burning wood. Some stoves are placed in front of the water features as decorations. Furthermore, there are even some stoves with a burning area in the middle surrounded by flowing water, which is designed to simulate a fire in water for displaying unique ornamental features.

(13) In fact, whether the stoves placed in front of the water features or the stoves with water surrounding the burning area, have an ornamental value to some extend, but still cannot reach the real ornamental effect of the flame burning on the water.

(14) In order to solve the above mentioned problems, the disclosure provides a decorative gas stove. FIGS. 1-5 are drawings according to some embodiments of the present disclosure.

(15) In some embodiments of the present disclosure (hereinafter some embodiments), as shown in FIGS. 1-5, the decorative gas stove 100 includes a stove body 1 and a viewing platform 2. A cavity 11 is defined in the stove body 1. An energy device 12 is provided inside the cavity 11 for storing gaseous fuel. A supply pipe 13 is provided inside the cavity 11 for transporting the gaseous fuel. A water tank 21 is provided on an upper end of the stove body 1 and a bottom of the water tank 21 is defined with a plurality of air outlet holes 211 communicated with the supply pipe 13. An ignition portion 22 is provided on a side wall of the water tank 21 for igniting the gaseous fuel flowing to a water surface through the air outlet holes 211 when the water tank 21 is stored with water.

(16) In the technical solution of the present disclosure, a plurality of air outlet holes 211 communicated with the supply pipe 13 of the energy device 12 are provided at the bottom of the water tank 21. When water is put into the water tank 21 and the stove is turned on, the energy device 12 delivers gaseous fuel to the air outlet holes 211 through the supply pipe 13, the gaseous fuel escapes from the bottom of the water tank 21 to the water surface, and the gas fuel escaping to the water surface is ignited by the ignition portion 22. Thus, the gaseous fuel burns on the water surface and produces flame, thereby achieving the ornamental effect of flame burning on water.

(17) In order to prevent the water in the water tank 21 from flowing back to the solenoid valve 4 and the supply pipe 13, the anti-backflow structure 3 includes a gas supply cavity 31, a movable plugging portion 32 and a reset portion 33. The gas supply cavity 31 is provided under the bottom of the water tank 21 and communicated with the supply pipe 13 and the air outlet holes 211. The movable plugging portion 32 is provided inside the gas supply cavity 31 and configured to move to a plugging position for plugging the air outlet holes 211 and to move to an avoidance position for communicating the supply pipe 13 and the air outlet holes 211. When the movable plugging portion 32 is located at the plugging position, the movable plugging portion 32 may plug the air outlet holes 211 when the gaseous fuel is not transported, thereby to prevent water from flowing back to the gas supply cavity 31. When the plugging portion is located at the avoidance position, the air outlet holes 211 are not blocked by the plugging portion, and the gaseous fuel may escape to the water surface from the air outlet holes 211. The movable plugging portion 32 is pushed from the plugging position to the avoidance position by the gaseous fuel due to the high pressure of gaseous fuel, when the energy device 12 outputs the gaseous fuel into the gas supply cavity 31, thereby to supplying the gaseous fuel. The reset portion 33 is provided inside the gas supply cavity 31 and opposite to the supply pipe 13. The reset portion 33 is configured to push the movable plugging portion 32 from the avoidance position to the plugging position when the energy device 12 stops supplying gaseous fuel, such that the air outlet holes 211 are blocked again to prevent the water from flowing back to the gas supply cavity 31, that is to say, the water is also prevented from flowing back to the supply pipe 13. The specific structure of the reset portion 33 is not limited, but may realize that when the pressure provided by the gaseous fuel disappears, the reset portion 33 may push the movable plugging portion 32 to the plugging position, thereby to block the air outlet holes 211. In some embodiments, the reset portion 33 is a spring, one end of the spring is against the inner wall of the gas supply cavity 31 on the side opposite to the supply pipe 13, and the other end of the spring is against the movable plugging portion 32.

(18) In order to make sure that the reset portion 33 may push the movable plugging portion 32 to accurately move to the plugging position in case of stopping gas fuel delivery. As shown in FIG. 2, the anti-backflow structure 3 further includes a limiting portion 34 provided inside the gas supply cavity 31 and located at the plugging position. The limiting portion 34 is configured to resist and restrict the movable plugging portion 32 at the plugging position when the reset portion 33 pushes the movable plugging portion 32 to move. The movable plugging portion 32 is limited at the plugging position, thereby to plug the air outlet holes 211. The specific structures of the movable plugging portion 32 and the limiting portion 34 are not limited. The structure of the limiting portion 34 is designed according to the specific structure of the movable plugging portion 32. In some embodiments, the movable plugging portion 32 is a rubber bulb, and the limiting portion 34 is a small projection provided on the bottom wall of the gas supply cavity 31 and under the corresponding air outlet holes 211, such that when the rubber bulb is moved below the air outlet holes 211, the small projection may press the rubber bulb to the plugging position.

(19) In order to make the gaseous fuel have such a enough pressure to push the movable plugging portion 32 to move when the gaseous fuel is transported, the energy device 12 includes a high pressure gas-supply system communicated with the supply pipe 13 and configured to adjust the gaseous fuel, generally to reduce the pressure. Thus, the pressure of the gaseous fuel may be adjusted to a suitable range, such that the gas fuel can reach the desired rated pressure and can push the movable plugging portion 32 to move. Meanwhile, the problem of water flowing back during the discharge of the gaseous fuel may be solved when the gaseous fuel has a sufficient discharge rate from the air outlet holes 211, thereby to control the burning range of the gaseous fuel to some extent when the gaseous fuel escapes from the air outlet holes 211 to the water surface, which may improve the manageability of the combustion flame.

(20) In order to avoid the water in the water tank 21 from interfering with the ignition of the gaseous fuel by the ignition portion 22, as shown in FIG. 1 and FIG. 3, the water tank 21 is defined with an overflow hole 212 configured to drain the water from the water tank 21 to an outside, thereby to control the water level height in the water tank 21. The height of the overflow hole 212 is less than the height of the ignition portion 22, thereby to prevent the water in the water tank 21 from entering into the ignition portion 22 and cause a safety problem. The bottom of the water tank 21 is provided with a drainage hole to facilitate water change.

(21) To specifically achieve ignition of the gaseous fuel escaping from the water surface by the ignition portion 22, the decorative gas stove 100 further includes a solenoid valve 4 provided on the supply pipe 13 for dividing the supply pipe 13 into a plurality of supply branches 131, and the ignition portion 22 is communicated with part of the supply branches 131. Thus, the gaseous fuel may be supplied to the ignition portion 22 through the supply branches 131. The decorative gas stove 100 also includes a pulse igniter 6. As shown in FIG. 3, FIG. 5 and FIG. 6, the pulse igniter 6 is similar to a battery box of a household gas stove. The pulse igniter 6 is used to provide current required for the ignition needle 9 mounted on the ignition portion 22. The ignition needle 9 is provided on the ignition portion 22 and extends to a location where the gaseous fuel escapes in the ignition portion 22, thereby to ignite the escaping gaseous fuel in the ignition portion 22 and to produce a flame to ignite the gas fuel escaping from the water surface. The ignition principle of the solenoid valve 4, the pulse igniter 6, the ignition needle 9 and the ignition portion 22 may refer to the cooktop of a household gas stove. In some embodiments of the present invention, the energy device 12 may be a gas cylinder. The cavity of the stove body 1 is provided with a corresponding installation seat 16 for the gas cylinder to be mounted in a restricted position. The installation seat 16 is defined with a hole corresponding to the shape of the gas cylinder bottom in the middle. The inner wall of the hole extends to the outside of the installation seat 16 to form a threaded hole, the gas cylinder bottom is locked by means of a bolt set in the threaded hole.

(22) To achieve the adjustment of the size of the ornamental flame to produce different ornamental effects, as shown in FIG. 5, each of the air outlet holes 211 is respectively communicated with each of the supply branches 131 and the gaseous fuel can be delivered to the air outlet holes 211 by the supply branches 131. The decorative gas stove 100 further includes a regulative switch 5 configured to control the energy device 12 to output the gaseous fuel to each of the supply branches 131 for adjusting the amount of the gaseous fuel flowing from the air outlet holes 211 by controlling the number of the air outlet holes 211 for gas flowing, thereby to control the size of the flame by burning the gaseous fuel on the water surface. In some embodiments, a plurality of the air outlet holes 211 are divided into two groups, two groups of the air outlet holes 211 are communicated to different supply branches 131, and the regulative switch 5 allows for two levels of flame size adjustment. One level is a small flame when one of the air outlet holes 211 group is turned on to communicated with the corresponding supply branch 131 for delivery of gaseous fuel, and the other is a large flame when both of the air outlet holes 211 groups are simultaneously turned on to communicated with the corresponding supply branches 131 for delivery of gaseous fuel.

(23) In order to install the water tank 21 on the stove body 1, as shown in FIG. 5, the stove body 1 further includes a storage table 14 provided at the upper end of the stove body 1 and a center of the storage table 14 is defined with an installation port 141. The water tank 21 is provided at the upper end of the stove body 1 by being installed in the installation port 141. A side of the storage table 14 is provided with a storage area 142. The storage area 142 is provided around the installation port 141 for placing objects.

(24) To ensure the safety of viewing the water flames, and meanwhile to avoid affecting the viewing effect of the water flames, as shown in FIG. 1, the decorative gas stove 100 further includes a viewing glass 7 for firebreak provided on the storage table 14 and around the installation port 141. The viewing glass 7 is configured to insulate the fire and includes several pieces of glass and a glass assembly portion 71. The glass assembly portion 71 is provided between each two adjacent pieces of glass to assemble the four pieces of glass into one piece of glass. That is to say, the viewing glass 7 assembled surrounds the water tank 21 to prevent the flame produced in the water tank 21 from spreading outwardly, which may ensure personal safety when viewing the water flames. Because the glass is transparent, the impact on the viewing is small. The glass assembly portion 71 may fix the pieces of glass at periphery of the water tank 21, and the specific structure of the glass assembly portion 71 is not limited. In some embodiments, the glass assembly portion 71 includes a locking piece provided at the upper end and the lower end of the connection between two adjacent glasses, and two ends of the locking piece are attached to the surface of the glass. Both ends of the locking piece are provided with through holes, and the glasses are also provided with openings corresponding to the through holes, thereby the glasses are locked by screws. The number of glasses in the viewing glass 7 is not limited, and is generally set according to the shape of the water tank 21. In some embodiments, the side wall of the water tank 21 is rectangular, correspondingly, the viewing glass 7 includes four pieces of glass, which are assembled and connected to each other to form the viewing glass 7 of a rectangle, thereby to surround the side wall of the water tank 21.

(25) In order to fix the water tank 21 at the installation port 141 and to define the installation position of the viewing glass 7 on the storage table 14, the storage table 14 is provided with a fixing block 15. The fixing block 15 is provided at intervals at the edge of the side wall of the water tank 21, to fix and lock the water tank 21 in the installation port 141, thereby to prevent accidents such as the water tank 21 falling out of the installation port 141. The viewing glass 7 is provided around the side wall of the water tank 21, such that the fixing block 15 may abut against the lower part of the viewing glass 7 at multiple positions on the edge of the side wall of the water tank 21, thereby to limit the installation position of the viewing glass 7. In some embodiments, the installation port 141 and the corresponding water tank 21 are rectangular. In order to fix the water tank 21 at the installation port 141, the four corners of the installation port 141 are respectively provided with the fixing block 15, and through holes are defined on the fixing block 15 and the water tank 21. By screws simultaneously passing through the through holes on the fixing block 15 and the water tank 21, the water tank 21 may be fixed at the installation port 141 by screws. Meanwhile, because the fixing block 15 is provided at the four corners of the water tank 21, the surface facing each glass of the fixing block 15 is set as a plane, thereby to simultaneously abut against and adhere to the surfaces of two adjacent glasses of the viewing glass 7, which may realize the limitation of the viewing glass 7.

(26) Since the flame continues to burn, the temperature of the viewing glass 7 will increase, and it is difficult for the viewing glass 7 made of current materials to pass the temperature rise test and meet the safety regulations without affecting the viewing effect. A thermal insulation structure 8 is provided on a side of the viewing glass 7 away from the water tank 21, which is used to prevent people from burning caused by direct contact with the viewing glass 7 during viewing. In some embodiments of the present invention, the thermal insulation structure 8 may be wire mesh, and the diameter of the wire mesh may be relatively large, thereby to avoid affecting the viewing effect of the flame on the water as much as possible.

(27) The above are only some embodiments of the present disclosure, and do not limit the scope of the present disclosure thereto. Under the concept of the present disclosure, equivalent structural transformations made according to the description and drawings of the present disclosure, or direct/indirect disclosure in other related technical fields are included in the scope of the present disclosure.
