DETAILED DESCRIPTION

[0066] The preferred embodiments of the present present application will be further described with reference to the drawings.

[0067] As shown in FIGS. 1 to 3, a water storage and jetting structure of toy water gun includes a housing 1, a water storage tank 2, a push rod 3, a trigger mechanism 4, an electric water jetting mechanism 5 for driving the push rod 3 to push forward water jetting, a spring 6 for pulling back the push rod 3 to return, a guide sleeve 7 and a fixed shaft 8, in which all of the water storage tank 2, the electric water jetting mechanism 5, the trigger mechanism 4, the push rod 3, the spring 6, the guide sleeve 7 and the fixed shaft 8 are disposed inside the housing 1. The water storage tank 2 is provided with a water suction port 201 and a water jetting port 202, each of the water suction port 201 and a water jetting port 202 is provided with a one-way valve (not shown in the figure), and the water suction port 201 is connected to an external water tank.

[0068] As shown in FIG. 1 and FIG. 2, the rear of the fixed shaft 8 is provided with a clamping slot 801 along its circumferential direction, and the housing 1 is provided with a clamping tab 101 matching with the clamping slot 801 at the corresponding position where the fixed shaft 8 is installed, so that the rear of the fixed shaft 8 is clamped with the clamping tab 101 through the clamping slot 801. The guide sleeve 7 is sleeved on the outside of the fixed shaft 8 so as to be moveable forward and backward, and the guide sleeve 7 includes a sleeve body 701, a circular front plate 702, and an annular rear plate 703. The spring 6 is sleeved on the fixed shaft 8, the front end of the spring 6 engageably contacts with the front end of the fixed shaft 8, the rear end of the spring 6 engageably contacts with the front side surface of the rear plate 703, and the inner diameter of the rear plate 703 is smaller than the diameter of the spring 6. The rear end of the push rod 3 is fixedly connected to the front side surface of the front plate 702, and the front of the push rod 3 is located in the water storage tank 2.

[0069] As shown in FIG. 1 and FIG. 3, the electric water jetting mechanism 5 includes a gear rack 501, a half gear 502, a plurality of transmission gears 503, a main gear 504 and a motor 505. In this embodiment, the gear rack 501 is fixedly installed on the surface of the sleeve body 701 of the guide sleeve 7 disposed at the rear of the push rod 3 in a front and rear direction, the main gear 504 is connected to an output shaft of the motor 505, the half gear 502 is connected to the main gear 504 through the plurality of transmission gears 503, and the gear rack 501 meshes with the teeth of the half gear 502. The number of teeth of the gear rack 501 is 3?5 teeth.

[0070] The motor 505 drives the main gear 504 to rotate, and drives the half gear 502 to rotate through the plurality of transmission gears 503. When the teeth of the half gear 502 mesh with the gear rack 501, the gear rack 501 pushes forward one tooth under the meshing action of the half gear 502. Accordingly, the guide sleeve 7 also moves forward one time under the drive of the gear rack 501, and at the same time, the one-way valve at the water suction port 201 is closed and the one-way valve at the water jetting port 202 is opened. Then, the guide sleeve 7 pushes the push rod 3 to squeeze the water in the water storage tank 2 and shoot a water bullet. With the continuous meshing of the gear rack 501 and the teeth of the half gear 502, the push rod 3 also continuously shoots multiple water bullets. Accordingly, while the guide sleeve 7 moves forward, because the front end of the spring 6 engageably contacts with the front end of the fixed shaft 8 and the rear end of the spring 6 engageably contacts with the rear end of the guide sleeve 7, the guide sleeve 7 compresses the spring 6 when it moves forward. Furthermore, because the rear of the fixed shaft 8 is clamped with the clamping tab 101 through the clamping slot 801, the fixed shaft 8 can be clamped in the housing 1 when the guide sleeve 7 moves forward, without moving with the guide sleeve 7. When the non-tooth part of the half gear 502 is turned to correspond to the gear rack 501, the gear rack 501 is separated from the half gear 502. Then, the spring 6 is no longer compressed or stretched by the guide sleeve 7 when it moves forward, and returns under the action of its own elasticity, and thus, the push rod 3 is pulled back to form a negative pressure environment in the water storage tank 2. At the same time, the one-way valve at the water jetting port 202 is closed, and the one-way valve at the water suction port 201 is opened. Then, water will be sucked into the water storage tank 2 from the external water tank under the negative pressure.

[0071] In order to make the spring 6 have a certain buffer time after return, reduce the degree of stretch or compression of the spring 6, and control the amount of water bullets, the number of teeth of the gear rack 501 is 3?5 teeth.

[0072] The water storage and jetting structure of toy water gun according to the present present application adopts the electric water jetting mechanism 5 to drive the push rod 3 to push forward water jetting, and under the driving action of the electric water jetting mechanism 5, the push rod 3 can continuously be pushed forward one or more times in accordance with the different driving modes of the electric water jetting mechanism 5, so as to achieve continuous water jetting one or more times. The amount of water jetting is determined by the distance of the push rod 3 pushed forward one time, and the number of times of water jetting is determined by the number of times of the push rod 3 pushed forward, which can be controlled by the electric water jetting mechanism 5. The effect of water jetting will not be affected due to the weakening of elastic force of the spring 6, and thus, the loss of the spring 6 is reduced.

[0073] This embodiment also discloses a specific structure of the trigger mechanism 4, as shown in FIG. 1, FIG. 4 and FIG. 5, including a touch switch 401, a touch block 402, and a trigger drive assembly for driving the touch block 402 to touch or leave the touch switch 401. The touch switch 401. as a trigger end of the trigger mechanism 4, is electrically connected to a signal input end of the motor 505. The touch switch 401 is disposed opposite to the touch block 402. The trigger drive assembly includes a translation seat 403, a sliding block 404, a first return spring 405, a push block 406, a first elastic press assembly 407, a first clamp block 408, a second clamp block 409, a second return spring 410 and a second elastic press assembly 411. The touch block 402 is fixedly disposed on the translation seat 403 and is opposite to the touch switch 401 in a front and back direction. The housing 1 is provided with a sliding slot in a front and back direction (omitted and not shown in the figure) matching with the sliding block 404. The sliding block 404 is fixedly disposed on the translation seat 403 and located in the sliding slot. The rear end of the first return spring 405 is connected to the translation seat 403, and the front end of the first return spring 405 engageably contacts with the housing 1. The push block 406 is fixedly disposed at the rear end of the translation seat 403. The first elastic press assembly 407 includes a first press block 4071, a first press spring 4072, a first sleeved shaft 4073 and a first pressed block 4074. The housing 1 is provided with a first through hole (omitted and not shown in the figure). The first pressed block 4074 is located inside the housing 1 and engageably contacts with the push block 406. The first press block 4071 is located outside the housing 1, the first sleeved shaft 4073 passes through the first through hole from outside to inside, the outer end of the first sleeved shaft 4073 is fixedly connected to the first press block 4071, and the inner end of the first sleeved shaft 4073 corresponds to the first pressed block 4074. The first press spring 4072 is wrapped on the first sleeved shaft 4073 and has an outer end located between a corresponding portion of the housing 1 and the first press block 4071. The first clamp block 408 is fixedly disposed on the translation seat 403, the second clamp block 409 is located in the upper front of the first clamp block 408, the upper end of the second return spring 410 is connected to the second clamp block 409, and the lower end of the second return spring 410 engageably contacts with the housing 1. The second elastic press assembly 411 includes a second press block 4111, a second press spring 4112, a second sleeved shaft 4113 and a second pressed block 4114. The housing 1 is provided with a second through hole (omitted and not shown in the figure). The second pressed block 4114 is located inside the housing 1 and engageably contacts with the second clamp block 409. The second press block 4111 is located outside the housing 1, the second sleeved shaft 4113 passes through the second through hole from outside to inside, the outer end of the second sleeved shaft 4113 is fixedly connected to the second press block 4111, the inner end of the second sleeved shaft 4113 corresponds to the second pressed block 4114. The second press spring 4112 is wrapped on the second sleeved shaft 4113 and has an outer end located between a corresponding portion of the housing 1 and the second press block 4111.

[0074] The first press block 4071 is pressed and held by hand to move the first sleeved shaft 4073 towards the inside of the housing 1 and squeeze the first pressed block 4074 to move, while the first press spring 4072 is squeezed. When the first press block 4071 is released, the first press block 4071 returns under the elastic force of the first press spring 4072. For the same reasons, the second press block 4111 is pressed and held by hand to move the second sleeved shaft 4113 towards the inside of the housing 1 and squeeze the second pressed block 4114 to move, while the second press spring 4112 is squeezed. When the second press block 4111 is released, the second press block 4111 returns under the elastic force of the second press spring 4112.

[0075] Upon triggering, the first press block 4071 is pressed and held by hand to squeeze the first pressed block 4074 so as to make the push block 406 move forward, and then make the entire translation seat 403 move forward under the guidance of the sliding block 404 and the sliding slot, so that the touch block 402 contacts the touch switch 401, and the touch switch 401 sends the corresponding signal to the motor 505 for operation, while compressing the first return spring 405 forward. The second press block 4111 is pressed and held by hand to squeeze the second pressed block 4114 so as to make the second clamp block 409 move downward and compress the second return spring 410 downward. In a case where the translation seat 403 moves forward, the second clamp block 409 moves to the lower part of the first clamp block 408, and at that time, the second press block 4111 is released, the second clamp block 409 moves upward under the elastic force of the second return spring 410 and forms a stable clamping structure together with the first clamp block 408. As a result, the translation seat 403 cannot move backward under the elastic force of the first return spring 405. When a return is required, the second pressed block 4114 is squeezed so as to make the second clamp block 409 move downward and compress the second return spring 410 downward. As a result, the second clamp block 409 is separated from the first clamp block 408, and the translation seat 403 moves backward to return under the elastic force of the first return spring 405.

[0076] Moreover, in other embodiments, the push rod and the spring can also be disposed in a front and rear direction along the same axis, the rear end of the push rod is connected to the front end of the spring, and the rear end of the spring is fixedly connected to the housing of toy water gun. When the electric water jetting mechanism drives the push rod forward to jet water, the spring is stretched forward. After the water jetting is completed, the spring will pull the push rod back under the action of its own elasticity.

[0077] In addition, it should be noted that the specific embodiments described in this specification can have different names of each of components. All equivalent or simple changes made according to the structure, features and principles described in the concept of the present present application are covered in the scope of protection of the present present application.
