The present present application relates to the technical field of toy guns, in particular to, a water storage and jetting structure of toy water gun.
The toy water gun is one of the most popular toys for children. Its main function is to suck water into the water storage tank of toy water gun, and then use its water jetting structure to spray the water out. At present, the water storage and jetting structure of toy water gun usually includes a water storage tank, a push rod, a spring, and a driving mechanism for driving the forward and backward translation of the push rod, in which the water storage tank is provided with a water suction port and a water jetting port, each of the water suction port and the water jetting port is provided with a one-way valve, the water suction port is connected to an external water source, and the front end of the push rod is located in the water storage tank. When sucking water, the driving mechanism drives the push rod to move backward and compress the spring so as to form a negative pressure environment in the water storage tank. At the same time, the one-way valve at the water jetting port is closed, and the one-way valve at the water suction port is opened. Then, water will be sucked into the water storage tank from the external water source under the negative pressure. When jetting water, the push rod is released, and the spring pushes the push rod to move forward under the action of its own elasticity. At the same time, the one-way valve at the water suction port is closed, and the one-way valve at the water jetting port is opened. Then, the push rod will squeeze the water in the water storage tank and spray the water out.
In the above water storage and jetting structure, because the power of jetting water is completely originated from the elasticity of the spring itself when it is compressed, it is very dependent on the performance of the spring itself. Because the spring releases the compressed elastic force at one time when jetting water, after a period time of use, the loss of the spring itself will affect the elastic performance of the spring, thus affecting the range of the shot water bullet. In addition, there is only one water bullet at one time, which cannot achieve continuous water jetting.
The problem to be solved by the present present application is to provide a water storage and jetting structure of toy water gun, which is able to reduce the loss of a spring and carry out continuous water jetting. The following technical solutions are adopted.
The present present application provides a water storage and jetting structure of toy water gun, comprising a housing, a water storage tank, a push rod and a trigger mechanism, in which the front part of the push rod is located inside the water storage tank, wherein the water storage and jetting structure of toy water gun further comprises an electric water jetting mechanism for driving the push rod to push forward water jetting and a spring for pulling back the push rod to return; wherein all of the water storage tank, the electric water jetting mechanism, the trigger mechanism, the push rod and the spring are disposed inside the housing, and a trigger end of the trigger mechanism is electrically connected to a signal input end of the electric water jetting mechanism; and wherein the rear of the push rod engageably contacts with the spring.
The water storage tank is provided with a water suction port and a water jetting port, each of the water suction port and the water jetting port is provided with a one-way valve, and the water suction port is connected to an external water tank. When sucking water, the one-way valve at the water jetting port is closed and the one-way valve at the water suction port is opened, and water will be sucked into the water storage tank from the external water tank under the negative pressure. When jetting water, the one-way valve at the water suction port is closed and the one-way valve at the water jetting port is opened, and the push rod will squeeze the water in the water storage tank.
Under the driving action of the electric water jetting mechanism, the push rod can continuously be pushed forward one or more times in accordance with the different driving modes of the electric water jetting mechanism, so as to achieve continuous water jetting one or more times.
The electric water jetting mechanism is used to drive the push rod forward to jet water. The amount of water jetting is determined by the distance of the push rod pushed forward one time, and the number of times of water jetting is determined by the number of times of the push rod pushed forward, which can be controlled by the electric water jetting mechanism, and the effect of water jetting will not be affected due to the weakening of elastic force of the spring. After the water jetting is completed, the push rod is pulled back by the spring and return so as to form a negative pressure environment in the water storage tank and suck water.
As the preferred embodiment of the present present application, the electric water jetting mechanism comprises a gear rack, a half gear, a plurality of transmission gears, a main gear and a motor; and the gear rack is fixedly installed on the push rod in a front and rear direction, the main gear is connected to an output shaft of the motor, the half gear is connected to the main gear through the plurality of transmission gears, and the gear rack meshes with the teeth of the half gear. The motor drives the main gear to rotate, and drives the half gear to rotate through the plurality of transmission gears. When the teeth of the half gear mesh with the gear rack, the gear rack pushes forward one tooth under the meshing action of the half gear. Accordingly, the push rod also moves forward one time under the drive of the gear rack and shoots a water bullet. With the continuous meshing of the gear rack and the teeth of the half gear, the push rod also continuously shoots multiple water bullets. When the non-tooth part of the half gear is turned to correspond to the gear rack, the gear rack is separated from the half gear. Then, the spring is no longer compressed or stretched by the push rod when it moves forward, and returns under the action of its own elasticity, and thus, the push rod is pulled back.
The number of teeth of the above-mentioned half gear affects the number of times that the push rod can continuously jet water, and the size of the tooth of the half gear affects the size of the water bullets in a one-time water jetting.
In order to make the spring have a certain buffer time after return, reduce the degree of stretch or compression of the spring, and control the amount of water bullets, as a further preferred embodiment of the present present application, the number of teeth of the gear rack is 3˜5 teeth.
As a further preferred embodiment of the present present application, the push rod and the spring are 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.
As another further preferred embodiment of the present present application, the rear of the push rod is provided with a guide sleeve and a fixed shaft, the fixed shaft is fixedly disposed inside the housing, the guide sleeve is sleeved on the outside of the fixed shaft so as to be moveable forward and backward, and the rear end of the push rod is fixedly connected to the front end of the guide sleeve; and the spring is sleeved on the fixed shaft, the front end of the spring engageably contacts with the front end of the fixed shaft, and the rear end of the spring engageably contacts with the rear end of the guide sleeve. When the electric water jetting mechanism drives the push rod forward, the guide sleeve moves forward at the same time. Because the front end of the spring engageably contacts with the front end of the fixed shaft and the rear end of the spring engageably contacts with the rear end of the guide sleeve, the guide sleeve compresses the spring when it moves forward.
As a further preferred solution of the present present application, the guide sleeve comprises a sleeve body, a circular front plate and an annular rear plate, the rear end of the push rod is fixedly connected to the front side surface of the front plate, the rear end of the spring engageably contacts with the front side surface of the rear plate, and the inner diameter of the rear plate is smaller than the diameter of the spring. In addition, in another preferred embodiment having a guide sleeve, the gear rack can also be disposed on the sleeve body of the guide sleeve.
As a further preferred embodiment of the present present application, the rear of the fixed shaft is provided with a clamping slot along its circumferential direction, and the housing is provided with a clamping tab matching with the clamping slot at the corresponding position where the fixed shaft is installed. The rear part of the fixed shaft is clamped with the clamping plate through the clamping slot, so that the fixed shaft can be clamped in the housing when the guide sleeve moves forward, without moving with the guide sleeve.
As a preferred embodiment of the present present application, the trigger mechanism comprises a touch switch, a touch block and a trigger drive assembly for driving the touch block to touch or leave the touch switch; the touch switch is used as a trigger end of the trigger mechanism; and the touch switch is disposed opposite to the touch block, and the touch block engageably contacts with a drive end of the trigger drive assembly.
As a further preferred embodiment of the present present application, the trigger drive assembly comprises a translation seat, a slide block, a first return spring, a push block, a first elastic press assembly, a first clamp block, a second clamp block, a second return spring and a second elastic press assembly, the touch block is fixedly disposed on the translation seat and is opposite to the touch switch in a front and back direction, the housing is provided with a slide slot in a front and back direction matching with the slide block, and the sliding block is fixedly disposed on the translation seat and located in the sliding slot; the rear end of the first return spring is connected to the translation seat, and the front end of the first return spring engageably contacts with the housing; the push block is fixedly disposed at the rear end of the translation seat, and the first elastic press assembly is disposed on the housing and engageably contacts with the push block; and the first clamp block is fixedly disposed on the translation seat, the second clamp block is located in the upper front of the first clamp block, the upper end of the second return spring is connected to the second clamp block, the lower end of the second return spring engageably contacts with the housing, and the second elastic press assembly is disposed on the housing and engageably contacts with the second clamp block.
The first elastic press assembly makes the push block move forward when being pressed, and then makes the entire translation seat move forward under the guidance of the slide block and the sliding slot, so that the touch block contacts the touch switch and the electric water jetting mechanism is triggered, while compressing the first return spring forward. The second elastic press assembly makes the second clamp block move downward when being pressed and compresses the second return spring downward. In a case where the translation seat moves forward, the second clamp block moves to the lower part of the first clamp block, and at that time, the second elastic press assembly is released, the second clamp block moves upward under the elastic force of the second return spring and forms a stable clamping structure together with the first clamp block. As a result, the translation seat cannot move backward under the elastic force of the first return spring. When a return is required, the second elastic press assembly is squeezed again so as to separate the second clamp block from the first clamp block, and the translation seat moves backward to return under the elastic force of the first return spring.
As a further preferred solution of the present present application, the first elastic press assembly comprises a first press block, a first press spring, a first sleeved shaft and a first pressed block, the housing is provided with a first through hole, the first pressed block is located inside the housing, the first press block is located outside the housing, the first sleeved shaft passes through the first through hole from outside to inside, the outer end of the first sleeved shaft is fixedly connected to the first press block, the inner end of the first sleeved shaft corresponds to the first pressed block, and the first press spring is wrapped on the first sleeved shaft and has an outer end located between a corresponding portion of the housing and the first press block; and the second elastic press assembly comprises a second press block, a second press spring, a second sleeved shaft and a second pressed block, the housing is provided with a second through hole, the second pressed block is located inside the housing, the second press block is located outside the housing, the second sleeved shaft passes through the second through hole from outside to inside, the outer end of the second sleeved shaft is fixedly connected to the second press block, the inner end of the second sleeved shaft corresponds to the second pressed block, and the second press spring is wrapped on the second sleeved shaft and has an outer end located between a corresponding portion of the housing and the second press block. Take the first elastic press assembly as an example, the first press block is pressed and held by hand to move the first sleeved shaft towards the inside of the housing and squeeze the first pressed block to move, while the first press spring is squeezed. When the first press block is released, the first press block returns under the elastic force of the first press spring.

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.
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.
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.
This embodiment also discloses a specific structure of the trigger mechanism 4, as shown in
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.
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.
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.
