[0040] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail by combining with the drawings and examples.

[0041] Example one

[0042] As Figures 1-10 shown, the embodiment discloses a water spraying device of a toy, which comprises a pump water mechanism 50, an atomizing mechanism, a rotating mechanism, a water tank 20, a water spraying pipeline and a water inlet pipe. The water tank 20 is provided with a partition 21, an atomizing hole 24, a water spraying hole 26, a water filling hole 27, a plug 28 and a water suction hole 25. The partition 21 is arranged at the bottom of the inner cavity of the water tank 20. The partition 21 divides the inner cavity of the water tank 20 into a first chamber 22 and a second chamber 23. The first chamber 22 and the second chamber 23 are communicated with each other above the partition 21. The atomizing hole 24 is communicated with the top of the first chamber 22. The water suction hole 25 is communicated with the bottom of the first chamber 22. The water spraying hole 26 is communicated with the bottom of the second chamber 23. The water filling hole 27 can be communicated with the first chamber 22 or the second chamber 23. Generally, the water filling hole 27 fills the water tank 20 with water. The plug 28 is detachably and sealingly connected with the water filling hole 27.

[0043] The outlet of the water suction pipe 30 is communicated with the water suction hole 25, the inlet of the water suction pipe 30 is arranged at the bottom of the toy shell 10, the water suction pipe 30 can be communicated with the outside of the toy shell 10, and the water suction pipe 30 is sealingly connected with the toy shell 10. A switching component is arranged at the inlet position of the water suction pipe 30, and the switching component is a first one-way valve 31. The first one-way valve 31 is used for unidirectionally guiding the water suction pipe 30, and the first one-way valve 31 limits the water to flow from the inlet to the outlet of the water suction pipe 30. In the case, the first one-way valve 31 is a rubber umbrella valve. In order to facilitate assembly, the first one-way valve 31 is installed on the toy shell 10, the first one-way valve 31 is slidingly connected with the toy shell 10 in the up-down direction, and the first one-way valve 31 is limitingly matched with the toy shell 10. When the first one-way valve 31 moves upward, the valve plate of the first one-way valve 31 blocks the inlet of the water suction pipe 30. When the first one-way valve 31 moves downward, the valve plate does not block the inlet of the water suction pipe 30. In addition, a filter screen 32 is also arranged at the inlet position of the water suction pipe 30, so as to prevent sundries from entering the water tank 20 and avoid causing pipeline blockage and affecting the normal use of the water spraying function. In order to facilitate disassembly, the filter screen 32 is also arranged on the toy shell 10. Of course, the switching component can also be a plug or an electrically controlled valve.

[0044] The atomizing mechanism comprises an atomizing piece 41 and a water suction piece 42. The atomizing piece 41 is arranged close to the atomizing hole 24, and preferably is installed in the atomizing hole 24 and sealingly connected with the atomizing hole 24. The atomizing hole 24 can be designed as a stepped hole to facilitate installation of the atomizing piece 41. The water suction piece 42 can be a cotton swab. One end of the water suction piece 42 abuts against the atomizing piece 41, and the other end of the water suction piece 42 extends into the first chamber 22 through the atomizing hole 24 and preferably abuts against the bottom of the first chamber 22, so as to ensure that the water suction piece 42 can reliably suck water when the water level in the first chamber 22 is low.

[0045] In order to prevent the water level of the water tank 20 from changing and causing the position of the water suction piece 42 to change, and facilitate cooperation between the water suction piece 42 and the atomizing piece 41, an upper limiting piece 29 and a lower limiting piece 2a for limiting the water suction piece 42 are arranged in the first chamber 22. The upper limiting piece 29 is arranged at the outer periphery of the atomizing hole, and the lower limiting piece 2a is arranged at the bottom of the first chamber 22 and opposite to the atomizing hole. In addition, an elastic piece 43, preferably a spring, is arranged at the end of the water suction piece 42 away from the atomizing piece 41. One end of the elastic piece 43 abuts against the bottom of the first chamber 22, and the other end of the elastic piece 43 abuts against the water suction piece 42. The end of the spring abutting against the water suction piece 42 can also be inserted into or clamped to the elastic piece 43, so as to facilitate assembly. In addition, the lower limiting piece 2a can also limit the elastic piece 43.

[0046] The water pumping mechanism 50 comprises a cylinder 51, a piston 52, a third one-way valve 53, a second one-way valve 54 and a water jet driving assembly. The piston 52 is arranged in the cylinder 51 and is sealingly connected with the inner wall of the cylinder 51. The water jet driving assembly drives the piston 52 to reciprocate in the cylinder 51. The water jet driving assembly can be a linear cylinder, or the water jet driving assembly is composed of a motor, a gear set and a push rod 57. The motor is drivingly connected with the input end of the gear set, the output end (an output gear 59) of the gear set is drivingly connected with the push rod 57, the output end (the output gear 59) of the gear set drives the push rod 57 to reciprocate, and the cooperation between the output gear 59 and the push rod 57 can refer to Figure 8 . The push rod 57 moves relative to the cylinder 51, the piston 52 is connected with one end of the push rod 57, and two racks 58 are arranged at the other end of the push rod 57. The two racks 58 are spaced apart and oppositely arranged. The output gear 59 is provided with a sector gear 5a, the sector gear 5a is arranged between the two racks 58, the rotation center of the sector gear 5a and the output gear 59 is coincident, and the sector gear 5a and the output gear 59 rotate synchronously. The sector gear 5a can be engaged with the racks 58. As shown in Figure 8 , the output gear 59 rotates clockwise. When the sector gear 5a is engaged with the right rack 58, the push rod 57 pushes the piston 52 to move downward. With the continuous rotation of the output gear 59, the sector gear 5a is disengaged from the right rack 58 and engaged with the left rack 58. At this time, the push rod 57 pushes the piston 52 to move upward. The above process is repeated. Of course, the water pumping mechanism 50 can also use a piston pump, a water pump or a pulse pump available on the market.

[0047] The cylinder 51 is provided with a water outlet 55 and a water inlet 56. The water outlet 55 and the water inlet 56 of the cylinder 51 are the water outlet and the water inlet of the water pumping mechanism 50. The water outlet 55 and the water inlet 56 are in communication with the inner cavity of the cylinder 51. The third one-way valve 53 is arranged at the water inlet 56, the water jet hole 26 is in pipeline communication with the water inlet 56, and the third one-way valve 53 limits the water inlet 56 to only allow water or air to enter the cylinder 51. The second one-way valve 54 is arranged at the water outlet 55, the water outlet 55 is in communication with the water jet pipeline, and the second one-way valve 54 limits the water or air in the cylinder 51 to only flow out of the water outlet 55. In this case, the third one-way valve 53 and the second one-way valve 54 are duckbill valves (back pressure type flexible one-way valves).

[0048] When the piston 52 moves away from the cylinder 51, the third one-way valve 53 is opened and the second one-way valve 54 is closed, so that the water in the water tank 20 can be sucked into the cylinder 51. When the piston 52 moves reversely, the third one-way valve 53 is closed and the second one-way valve 54 is opened, so that the water in the cylinder 51 can be sprayed, thereby realizing water spraying.

[0049] The water spray system includes a base pipe 61, a rotating pipe 62, and a seal 63. The base pipe 61 is fixed relative to the cylinder body 51, and one end of the base pipe 61 is connected to the water outlet 55. One end of the rotating pipe 62 is inserted into and connected to the other end of the base pipe 61, and the rotating pipe 62 can rotate relative to the base pipe 61. A spray gun 64 can be optionally installed at the other end of the rotating pipe 62. The spray gun 64 can increase the water pressure of the sprayed water, thereby making the water spray farther. The spray direction can be changed by rotating the rotating pipe 62.

[0050] A sealing element 63 is provided at the connection between the rotating tube 62 and the base tube 61. It is made of silicone or rubber and includes an outer tube portion 65, a connecting portion 66, and an inner tube portion 67 connected in sequence. The outer tube portion 65 and the inner tube portion 67 are coaxially arranged, with the inner tube portion 67 located within the outer tube portion 65. A mounting groove 11, adapted to the outer diameter of the outer tube portion 65, is provided on the outer shell 10 of the toy. A through hole 12 for the rotating tube 62 to pass through is provided at the bottom of the mounting groove 11. A sealing ring 68 is provided at the end of the base tube 61 where it connects to the rotating tube 62. The sealing ring 68 is fitted onto the base tube 61, with a portion extending out of the base tube 61. Preferably, the sealing ring 68 and the base tube 61 are integrally formed. The connecting part 66 abuts against the port of the sealing ring 68 and the bottom of the mounting groove 11, the outer tube part 65 abuts against the outer wall of the sealing ring 68 and the groove wall of the mounting groove 11, and the inner tube part 67 abuts against the inner wall of the sealing ring 68 and the outer wall of the rotating tube 62. With this arrangement, even if the rotating tube 62 is pulled out, it will not damage the sealing of the toy shell 10, and the water pumping mechanism 50 can be set in the sealed inner cavity of the toy, which is particularly suitable for water toys, amphibious toys, etc.

[0051] A rotating mechanism drives the rotating tube 62 to rotate. It includes a rotating drive assembly 71 and a turntable 72. The turntable 72 is rotatably connected to the outside of the toy's outer shell 10, and the turntable 72 is in a limiting fit with the toy's outer shell 10. The rotating drive assembly 71 is installed inside the toy's outer shell 10 and has an output shaft that passes through the toy's outer shell 10 and is connected to the turntable 72 (in this case, a small gear is provided on the output shaft, and a large gear is provided on the turntable 72; the transmission connection is completed through the meshing of the small gear and the large gear). The output shaft is sealed to the toy's outer shell 10. The rotating drive assembly 71 can be a motor with a reducer. The rotating tube 62 and the spray gun 64 are limited and positioned on the turntable 72. The rotating tube 62 passes through the rotation center of the turntable 72 and connects to the base tube 61. A through hole for the rotating tube 62 to pass through is provided at the rotation center of the turntable 72. The turntable 72 can be used for design to enhance the toy's aesthetics. By combining it with remote control technology, the turntable 72 can be rotated, thereby achieving remote control of the water spray direction, making the toy more fun.

[0052] The first chamber 22 and the second chamber 23 are separated by a partition 21, while ensuring that the first chamber 22 and the second chamber 23 can be connected. As the water pumping mechanism 50 operates, the water level in the water tank 20 drops until the water in the second chamber 23 is exhausted. Due to the partition 21, a certain amount of water can still be retained in the first chamber 22 for spraying, preventing the atomizing plate 41 from drying out. The water consumption of the atomizing plate 41 during continuous operation for N hours (e.g., 1 hour) can be pre-determined, and the height of the partition 21 can be set accordingly to ensure that the atomizing plate 41 can continue to operate for N hours even after the water in the first chamber 22 is exhausted. This invention allows the use of ordinary spray plates without protective functions, which is beneficial for product cost control. When the plug 28 seals the water inlet 27 and the toy is placed in water (ensuring the inlet of the water pump 30 can contact water), if there is a significant amount of water in the water tank 20, the water level in the tank 20 will drop as the pumping mechanism 50 is used, creating a negative pressure within the tank 20. Conversely, if the water level in the tank 20 is low or empty, the pumping mechanism 50 will continuously draw air from the tank, creating further negative pressure. When the negative pressure in the tank 20 reaches a certain level, the first one-way valve 31 will open, allowing water from outside the toy to be drawn into the tank 20 through the water pump 30, achieving automatic water replenishment. This ensures continuous water spray when the toy is playing on the water, eliminating the need for mid-play replenishment. When no pumping is required, the water in the water pump 30 will force the first one-way valve 31 to close, preventing leaks in the tank 20.

[0053] Example 2

[0054] The difference between this embodiment and Embodiment 1 is that the inner cavity of the water tank 20 does not have a partition 21. Instead, the inner cavity of the water tank 20 is divided into a deep water level zone and a shallow water level zone. Specifically, the bottom of the inner cavity of the water tank 20 can be set as a slope, with the upper half of the slope corresponding to the shallow water level zone and the lower half of the slope corresponding to the deep water level zone. Alternatively, a step can be set at the bottom of the inner cavity of the water tank 20, with the area above the step being the shallow water level zone and the area below the step being the deep water level zone. Of course, the water tank 20 can also be tilted and placed on the toy to achieve the division between the deep and shallow water level zones. The atomizing hole 24 connects to the deep water level zone, and the water suction member 42 extends to the bottom of the deep water level zone, while the spray hole 26 is located at the bottom of the shallow water level zone.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
