Description

Technical Field

[0001] This utility model relates to the field of toy technology, and in particular to an amphibious toy. Background Technology

[0002] Existing amphibious toys primarily rely on four hollow wheels for buoyancy. This necessitates waterproofing the power supply and electrical components (such as the wheel drive motors). Generally, considering factors like waterproofing, installation space, and aesthetics, amphibious toys typically feature a sealed interior cavity to house these components. Currently, this sealed cavity is usually achieved by applying sealant to the seams. This method is usually manual, which is susceptible to issues like uneven sealant application and scratches during assembly, making it difficult to guarantee a reliable seal. Furthermore, if the toy car is disassembled after leaving the factory, the cured sealant is easily damaged, resulting in a poor seal upon reassembly and leading to customer complaints.

[0003] Furthermore, to enhance the fun of toys, more and more functions are being added, with water spraying being one of them. Currently, almost all amphibious toys have a water spraying function. The water spraying mechanism is generally located inside the toy car's cavity, with the water outlet connected to a water pipe leading to the outside of the outer shell. The water pipe and the outer shell are sealed with waterproof glue. However, this method of applying waterproof glue relies on manual operation, so the waterproofing effect is not guaranteed, and the waterproof seal is easily damaged (e.g., the water pipe is pulled out), causing water to enter the toy car's cavity. Additionally, most existing amphibious toys spray water forward. Although the direction of the water spray can be adjusted by changing the direction of the toy car's movement, this flexibility is relatively limited. Utility Model Content

[0004] The purpose of this invention is to provide an amphibious toy with good waterproof sealing, a water spraying function, and flexible adjustment of the water spraying direction.

[0005] To achieve the above objectives, this utility model discloses an amphibious toy, comprising:

[0006] The outer casing includes an upper casing, a lower casing, and a casing edge seal. The casing edge seal is disposed along the outer edge of the lower casing and is detachably connected to the outer edge of the lower casing. The upper casing is detachably connected to the lower casing, and the outer edges of the upper casing and the lower casing clamp the casing edge seal. An installation chamber is formed between the upper casing and the lower casing.

[0007] A walking device includes wheels and a drive mechanism. The drive mechanism is disposed in an installation chamber. The outer casing has wheel holes corresponding to the wheels. The drive mechanism has an extension portion and a drive shaft corresponding to the wheels. A wheel seal is fitted on the extension portion. The extension portion is placed in the wheel hole, and the wheel seal seals the gap between the extension portion and the wheel hole. The drive shaft extends from the extension portion and is connected to the wheel. The drive shaft is sealed to the extension portion.

[0008] A water spray mechanism includes a water tank, a pump assembly, a base tube, a rotating tube, and a water spray seal. The pump assembly, base tube, and water spray seal are disposed within an installation chamber. The rotating tube is disposed outside a housing, which has a through hole for the rotating tube to pass through. The base tube is fixed in position relative to the housing. The first end of the base tube is positioned near the through hole, and the second end of the base tube connects to the outlet of the pump assembly. The inlet of the pump assembly connects to the inner cavity of the water tank. The first end of the rotating tube is the water spray outlet, and the second end of the rotating tube passes through the through hole and connects to the base tube. The rotating tube is rotatable relative to the base tube. The water spray seal simultaneously seals the gaps between the base tube and the housing, the rotating tube and the housing, and the rotating tube and the base tube.

[0009] By incorporating sealing elements along the shell edge, waterproof sealing between the upper and lower shells is ensured. Similarly, wheel seals guarantee a waterproof seal between the drive mechanism and the outer shell, and water spray seals ensure a waterproof seal between the water spray pipes and the outer shell. This effectively isolates the installation chamber from the outside of the toy car, guaranteeing its waterproof and airtight design and enabling amphibious use. Furthermore, the direction of the water spray outlet can be changed by rotating the rotating tube, offering convenient and flexible operation. The water spray seals also ensure that inserting or removing the rotating tube from the outside of the shell does not compromise the waterproof seal between the inside and outside of the shell. The flexible water spray pipe configuration also facilitates toy assembly and maintenance.

[0010] Preferably, the shell edge seal is embedded in the outer edge of the lower shell; the side of the shell edge seal that abuts against the outer edge of the upper shell has a groove, and the outer edge of the upper shell has a protrusion that matches the groove, the protrusion engaging with the groove; the upper shell also has several upper connecting posts, and the lower shell has lower connecting posts corresponding to the upper connecting posts; the shell edge seal partially extends to form a sealing part corresponding to each of the lower connecting posts, the upper and lower connecting posts clamping the sealing part; the upper and lower shells are connected by screws, the screws passing through the lower connecting posts and the sealing part in sequence before being threaded into the upper connecting posts. With this configuration, the shell edge seal can be pre-installed on the lower shell during assembly, ensuring accurate positioning of the shell edge seal and guaranteeing waterproof sealing. The groove on the shell edge seal engages with the protrusion on the upper shell, providing a larger waterproof sealing contact surface, further ensuring the waterproof sealing of the outer shell, and making alignment of the upper and lower shells easier. Furthermore, the above configuration, while ensuring waterproof sealing, also facilitates assembly.

[0011] Preferably, the water spray seal comprises an outer tube, a connecting part, and an inner tube connected in sequence, the outer tube and the inner tube being coaxially arranged, and the inner tube being located within the outer tube; the outer shell is provided with a mounting groove, and the through hole is located at the bottom of the mounting groove; the first end of the base tube is also provided with a sealing ring, the sealing ring being sleeved on the base tube, and the sealing ring partially extending out of the base tube; the connecting part abuts against the port of the sealing ring and the bottom of the mounting groove, the outer tube abuts against the outer wall of the sealing ring and the groove wall of the mounting groove, and the inner tube abuts against the inner wall of the sealing ring and the outer wall of the second end of the rotating tube; the surface of the inner tube abutting against the second end of the rotating tube is provided with at least one raised edge. This type of water spray seal has a simple structure, a large waterproof sealing contact surface, and good waterproofing effect. By adding an installation groove, the waterproof sealing performance is improved, and the positioning and installation of the base tube is also facilitated. During assembly, the water spray seal can be first placed on the sealing ring, and then inserted into the installation groove, thus completing the first-end positioning of the base tube quickly and conveniently. The raised edge further ensures better sealing between the base tube and the rotating tube.

[0012] Preferably, the system further includes a rotating mechanism for driving the rotating tube to rotate; the rotating mechanism includes a rotating drive assembly and a turntable, the turntable being rotatably connected to the outside of the housing and having a limiting fit with the housing; the rotating drive assembly is installed in the mounting chamber, the rotating drive assembly has an output shaft, the output shaft passes through the housing and is drively connected to the turntable, the output shaft being sealed to the housing; the rotating tube is limited and positioned on the turntable, and the center of the turntable has a through hole for the second end of the rotating tube to pass through. By setting up the rotating mechanism and combining it with the remote control technology of toy cars, the direction of water spray can be remotely controlled, making the water spraying function of the toy car more flexible and greatly enhancing the fun of the toy car.

[0013] Preferably, the top of the water tank is also provided with a water inlet and a plug. The water inlet communicates with the inner cavity of the water tank, and the plug is detachably and sealingly connected to the water inlet. With this configuration, the toy car can be actively replenished with water.

[0014] Preferably, the system also includes a water pumping pipe and a switching component for switching the water pumping pipe on and off. The inlet of the water pumping pipe is located at the bottom of the lower shell and is sealed to the lower shell. The outlet of the water pumping pipe connects to the inner cavity of the water tank. The switching component is a first one-way valve, a plug, or an electrically controlled valve. Taking the first one-way valve as an example, after the above configuration, the inner cavity of the water tank can be sealed. Using a pumping mechanism with vacuuming capability, when the toy is placed in water, the water level in the tank drops and forms a negative pressure as the pumping mechanism is used (when there is a lot of water in the tank), or the pumping mechanism continuously pumps air from the tank to form a negative pressure (when the water level in the tank is low or there is no water). When the negative pressure reaches a certain level, the first one-way valve can be opened, and water from outside the toy can be drawn into the water tank through the water pumping pipe, achieving automatic water replenishment. This allows the water spray to continue when the toy is playing on the water without the need for mid-way water replenishment. When water pumping is not needed, the first one-way valve is closed to prevent water leakage from the water tank. When the on / off component is set as a plug or an electrically controlled valve, when water needs to be pumped, the plug is pulled out or the electrically controlled valve is opened, the inlet of the water pumping pipe is placed in the water, and the water tank can also form a seal.

[0015] Preferably, the system further includes an inlet pipe, an inlet seal, and a pump seal; the water tank is detachably connected to the outside of the housing; the inlet of the pump assembly is connected to the inner cavity of the water tank via the inlet pipe; the inlet seal simultaneously seals the gap between the inlet pipe and the housing, and the gap between the inlet pipe and the water tank; the pump seal simultaneously seals the gap between the outlet of the pump pipe and the housing, and the gap between the outlet of the pump pipe and the water tank. The inlet pipe facilitates the connection between the pump assembly and the water tank. The inlet and pump seals ensure waterproof sealing of the installation cavity, and the installation and removal of the water tank will not affect it.

[0016] Preferably, the water pump assembly includes a cylinder, a piston, a third one-way valve, a second one-way valve, and a water pump drive assembly. The piston is placed in the cylinder and is sealed to the inner wall of the cylinder. The water pump drive assembly drives the piston to reciprocate within the cylinder. The outlet and inlet are located on the cylinder. The third one-way valve is located at the inlet, and the inner cavity of the water tank is connected to the inlet via the third one-way valve. The second one-way valve is located at the outlet, and the outlet is connected to the second end of the base tube via the second one-way valve. This configuration of the water pump assembly results in a simple structure.

[0017] Preferably, the system further includes an atomizing mechanism comprising an atomizing plate and a water-absorbing component. The water tank has an atomizing hole that connects to a first chamber. The atomizing plate is embedded in the atomizing hole and is sealed to the atomizing hole. A partition is provided at the bottom of the inner cavity of the water tank, dividing the inner cavity into a first chamber and a second chamber, which are interconnected. Alternatively, the inner cavity of the water tank is divided into a deep water level zone and a shallow water level zone. One end of the water-absorbing component abuts against the atomizing plate, and the other end extends through the atomizing hole to the bottom of the first chamber or the bottom of the deep water level zone. The inlet of the pump assembly connects to the bottom of the second chamber or the bottom of the shallow water level zone. Adding an atomizing plate to the water tank gives the toy car a spray function, enhancing its fun factor. The water tank's interior is divided into a first chamber and a second chamber by a partition, while ensuring that the two chambers are connected. When the water in the second chamber is used up, the partition allows a certain amount of water to remain in the first chamber for spraying. Alternatively, by setting up deep and shallow water levels, the remaining water in the deep water level can continue to supply the atomizing plate, thus extending the spraying time and preventing the atomizing plate from drying out. Toy cars can use ordinary spray plates without protective functions, which is beneficial for product cost control.

[0018] Preferably, the device further includes a terminal seal and a terminal assembly. The housing has a connecting hole that connects to the mounting chamber. The terminal seal and terminal assembly are placed in the mounting chamber. The terminal assembly includes a circuit board and at least one terminal interface. The terminal interface is located on the same side of the circuit board. The circuit board is detachably connected to the housing, and the terminal interface is placed in the connecting hole. The terminal seal is pressed between the circuit board and the housing, and the terminal seal has a through hole for the terminal interface to pass through. With this configuration, the terminal interface is placed in the connecting hole. Functional components installed outside the housing, such as lights, sprayers, and speakers, can be wired to the terminal interface. The terminal interface can then be connected to a power supply and control component placed in the sealed cavity via the circuit board, thereby achieving power supply and control. By sealing the gap between the housing and the circuit board with the terminal seal, water from outside the housing can be prevented from entering the sealed cavity, achieving waterproofing. Moreover, this waterproof structure is not easily damaged, and the connection of the terminal interface does not affect the stability of the waterproof structure, resulting in high waterproof reliability. In addition, segmented wiring through the terminal assembly facilitates product assembly and maintenance.

[0019] Preferably, the toy car also includes at least one interactive component disposed on the exterior of the housing, wherein the interactive component is one or more of a light source, a speaker, and a sound and light device. The addition of the interactive component can enhance the fun of the toy car.

[0020] Preferably, four wheels are provided; the drive mechanism includes two sets of wheel drive assemblies, one set synchronously driving the two wheels located on the left side of the housing, and the other set synchronously driving the two wheels located on the right side of the housing; each wheel drive assembly includes a mounting shell, a drive motor, and a gear set, both of which are mounted on the mounting shell, and the drive motor is connected to the corresponding drive shaft of the wheel via the gear set; the extension portion is provided on the mounting shell. With this configuration, the drive mechanism can be considered as two independent modules, facilitating assembly and ensuring waterproofing of the housing. Furthermore, this drive mechanism only requires differential speed operation of the left and right wheels to achieve turning, which is easier than the dedicated turning mechanism of traditional remote control cars. This reduces the difficulty of combining wheel steering with the toy car's sealing, allowing the toy car to have both steering functionality and waterproofing.

[0021] This utility model has the following beneficial effects:

[0022] This invention ensures a waterproof seal between the upper and lower shells by incorporating a shell-edge seal, a waterproof seal between the drive mechanism and the outer shell by incorporating a wheel seal, and a waterproof seal between the water spray pipe and the outer shell by incorporating a water spray seal. This effectively isolates the installation chamber from the outside of the toy car, ensuring the waterproof and airtight seal of the installation chamber and allowing the toy car to be used both on land and water. Furthermore, the direction of the water spray outlet can be changed by rotating the rotating tube, making operation convenient and flexible. The water spray seal also ensures that inserting or removing the rotating tube from the outside of the outer shell does not compromise the waterproof seal between the inside and outside of the outer shell. The water spray pipe design is more flexible and facilitates the assembly and maintenance of the toy. Attached Figure Description

[0051] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0052] like Figures 1-21 As shown, this utility model discloses an amphibious toy, which includes a shell, a walking device, a water spraying mechanism, a rotating mechanism, and a misting mechanism. This case focuses on the above-mentioned components and mechanisms, which does not exclude the possibility that the toy car of this utility model is not equipped with batteries, remote controls, remote control circuits (built into the toy car) that are common in conventional toy cars. However, these components mentioned later are not the focus of this case and will not be elaborated here.

[0053] The outer casing includes an upper shell 11, a lower shell 12, and a shell edge seal 13. The upper shell 11 and the lower shell 12 are detachably connected, forming an installation chamber 14 between them. In this case, the upper shell 11 and the lower shell 12 are connected by screws. The upper shell 11 has several upper connecting posts 111 spaced along its outer edge. The lower shell 12 has lower connecting posts 121 corresponding to the upper connecting posts 111. Screws pass through the lower connecting posts 121 and are threadedly connected to the upper connecting posts 111. The lower connecting posts 121 are hollow, while the upper connecting posts 111 have blind holes inside. Screws can be self-tapping connected to the blind holes, or internal threads can be pre-set in the blind holes.

[0054] The shell edge seal 13 is disposed along the outer edge of the lower shell 12, and is attached to the outer edge of the lower shell 12. The shell edge seal 13 has a closed-loop structure and is detachably connected to the outer edge of the lower shell 12. Preferably, the shell edge seal 13 is embedded in the outer edge of the lower shell 12, and the outer edge of the lower shell 12 has a groove 125 that mates with the shell edge seal 13. This ensures accurate positioning of the shell edge seal 13 and facilitates the assembly of the outer shell. When the upper shell 11 and the lower shell 12 are assembled, the upper shell 11 and the lower shell 12 clamp the shell edge seal 13 to achieve a seal between them. Specifically, a groove 131 is provided on the side of the shell edge seal 13 that abuts against the outer edge of the upper shell 11, and a protrusion 112 that matches the groove 131 is provided on the outer edge of the upper shell 11. The protrusion 112 and the groove 131 are inserted into each other, which not only makes the waterproof sealing contact surface larger and further ensures the waterproof sealing performance of the shell, but also makes it easier to align the upper shell 11 and the lower shell 12.

[0055] Because the upper shell 11 and the lower shell 12 are connected by screws, the shell extends along the seal 13 to form a sealing part 132 that corresponds one-to-one with the lower connecting post 121. When the upper shell 11 and the lower shell 12 are locked, the upper connecting post 111 and the lower connecting post 121 clamp the sealing part 132 to prevent water from seeping into the interior of the toy car (installation chamber 14) from the screw connection. A hole for the screw to pass through can be pre-drilled on the sealing part 132.

[0056] The walking device includes wheels 21 and a drive mechanism. The wheels 21 are hollow to ensure the toy car can float on water. There are four wheels 21, two on each side of the toy car. The drive mechanism is located in the mounting chamber 14 and includes two sets of wheel drive assemblies 22. One set of wheel drive assemblies 22 synchronously drives the two wheels 21 located on the left side of the outer shell, and the other set of wheel drive assemblies 22 synchronously drives the two wheels 21 located on the right side of the outer shell. The wheel drive assembly 22 includes a mounting shell 221, a drive motor 222, a gear set, and two drive shafts 223. The mounting shell 221 is screwed to the lower shell 12. The drive motor 222, gear set, and drive shafts 223 are all mounted on the mounting shell 221. The drive motor 222 is connected to the drive shaft 223 via the gear set, and each drive shaft 223 corresponds to one wheel 21. The outer casing has wheel holes 15 corresponding to the wheels 21 (formed by the upper casing 11 and the lower casing 12). The mounting casing 221 has an extension 224 corresponding to and fitted to the wheel holes 15. The extension 224 is placed in the wheel hole 15 (the extension 224 can extend a certain distance out of the wheel hole 15 to ensure the installation and waterproofing of the wheel seal 225). The drive shaft 223 extends from the extension 224 to the outside of the outer casing and is connected to the wheel 21. The drive shaft 223 and the extension 224 are sealed together by a sealing ring. At the same time, the wheel seal 225 is fitted on the extension 224 to seal the gap between the extension 224 and the wheel hole 15 to prevent external water from entering the mounting chamber 14 from the drive mechanism.

[0057] The drive mechanism can be considered as two independent modules, which facilitates assembly and also makes it easier to achieve waterproofing of the outer shell. In addition, this drive mechanism only requires the differential speed of the left and right wheels 21 to achieve turning. Compared with the traditional remote control car that has a dedicated turning mechanism, the compatibility between the steering of the wheels 21 and the sealing of the toy car is easier, so that the toy car has both steering function and waterproof sealing.

[0058] With the above-described design, the mounting cavity of the outer shell is essentially sealed, ensuring waterproofing. This sealed cavity provides a safe mounting location for electrical components requiring waterproofing, such as motors, batteries, and control circuit boards. Furthermore, the sealed waterproof structure is not easily damaged; even after disassembly and reassembly by the consumer, the waterproof seal can be restored to its original state without the need for manual re-adhesion. In addition, with the rise of assembly toys, this invention balances the ease of assembly and success rate of toy cars, offering greater possibilities for designing amphibious toy cars that consumers can assemble themselves.

[0059] The water spray mechanism includes a water tank 31, a pump assembly 32, a base pipe 33, a rotating pipe 34, a pumping pipe 35, an inlet pipe 36 (in the corresponding attached figure, the inlet pipe 36 conceals the rubber hose located in the middle of the pipe), a third one-way valve 371, a second one-way valve 372, an on / off component, a water spray seal 38, an inlet seal 39, and a pumping seal 3a. The on / off component is the first one-way valve 373. The pump assembly 32, the base pipe 33, the inlet pipe 36, the inlet seal 39, and the water spray seal 38 are disposed within the mounting chamber 14. The rotating pipe 34 is disposed outside the outer casing. A through hole 113 is provided on the outer casing (upper casing 11) for the rotating pipe 34 to pass through. This through hole 113 connects to the mounting chamber 14. Preferably, the diameter of the through hole 113 is adapted to the outer diameter of the second end of the rotating pipe 34.

[0060] The water tank 31 is detachably connected to the upper shell 11 by screws. The water tank 31 is provided with a water intake hole 311, a water spray hole 312, a water filling hole 313, a plug 314, and a partition 315. The partition 315 is located at the bottom of the inner cavity of the water tank 31, dividing the inner cavity of the water tank 31 into a first chamber 316 and a second chamber 317, and the first chamber 316 and the second chamber 317 are interconnected above the partition 315. The water intake hole 311 is connected to the bottom of the first chamber 316, and the water spray hole 312 is connected to the bottom of the second chamber 317. The water filling hole 313 is located at the top of the water tank 31 and is connected to the inner cavity of the water tank 31. The plug 314 detachably seals the water filling hole 313. Of course, the partition 315 can be omitted, and the inner cavity of the water tank 31 can be divided into a deep water zone and a shallow water zone. For example, the bottom of the inner cavity of the water tank 31 can be made into a slope, with the upper half of the slope corresponding to the shallow water zone and the lower half of the slope corresponding to the deep water zone. Alternatively, a step can be made at the bottom of the inner cavity of the water tank 31, with the area above the step being the shallow water zone and the area below the step being the deep water zone. The water tank 31 can also be tilted and mounted on the toy to achieve the division between the deep and shallow water zones. The water intake hole 311 and the water spray hole 312 are located at the bottom of the shallow water zone.

[0061] The inlet of the water-pumping pipe 35 is located at the bottom of the lower shell 12, allowing it to be submerged when the toy car is placed in water. The inlet of the water-pumping pipe 35 is secured to the lower shell 12 with screws, and a sealing gasket or sealing ring is used to seal the connection. The outlet of the water-pumping pipe 35 passes through the outer shell and connects to the water-pumping hole 311 on the water tank 31. The outlet of the water-pumping pipe 35 cooperates with the upper shell 11 to limit the water-pumping seal 3a, which simultaneously seals the gaps between the outlet of the water-pumping pipe 35 and the outer shell, as well as the gaps between the outlet of the water-pumping pipe 35 and the water tank 31. This arrangement ensures that the water-pumping pipe 35 passing through the mounting chamber 14 does not affect the airtightness of the mounting chamber 14.

[0062] The first one-way valve 373 unidirectionally guides the water pumping pipe 35. In this case, the first one-way valve 373 is a one-way umbrella valve. A support member 122 is provided in the lower shell 12 to block the inlet of the water pumping pipe 35. The inlet of the water pumping pipe 35 is sealed to the outer edge of the support member 122. Several water passage holes 123 are arranged on the support member 122. The handle of the one-way umbrella valve is slidably connected to the support member 122, and the one-way umbrella valve is in a limiting fit with the support member 122 (achieved by the valve plate of the one-way umbrella valve and the inverted buckle of the handle being limited by the support member 122). The valve plate of the one-way umbrella valve is located on the side of the support member 122 closer to the outlet of the water pumping pipe 35. When the one-way umbrella valve moves downward, its valve plate can block all the water passage holes 123. When the one-way umbrella valve moves upward, the valve plate moves away from the support member 122, and the water passage holes 123 connect to the water pumping pipe 35. A filter screen 124 is also provided on the side of the support 122 away from the water pipe 35 to intercept larger debris from entering the water pipe 35. The filter screen 124 can be screwed to the bottom of the lower shell 12.

[0063] Of course, the on / off component can also be a plug or an electrically controlled valve. The water pipe 35 can be turned on or off by pulling out or inserting the plug. The filter screen 124 can be designed as a mesh so that the plug can be inserted into it. The electrically controlled valve can be controlled remotely.

[0064] The water pump assembly 32 includes a cylinder 321, a piston 322, and a water pump drive assembly. The piston 322 is placed in the cylinder 321 and is sealed to the inner wall of the cylinder 321. The piston 322 can slide within the cylinder 321. The water pump drive assembly drives the piston 322 to reciprocate within the cylinder 321. The water pump drive assembly can be a linear cylinder, or it can be composed of a motor, a gear set, and a push rod 323. The motor is connected to the input end of the gear set, and the output end of the gear set (output gear 324) is connected to the push rod 323. The output end of the gear set (output gear 324) drives the push rod 323 to reciprocate. The relationship between the output gear 324 and the push rod 323 can be described by referring to... Figure 14 The push rod 323 moves relative to the cylinder 321. The piston 322 is connected to one end of the push rod 323. Two racks 325 are provided at the other end of the push rod 323. These two racks 325 are spaced apart and arranged opposite each other. A sector gear 326 is provided on the output gear 324. The sector gear 326 is positioned between the two racks 325. The rotation centers of the sector gear 326 and the output gear 324 coincide, and they rotate synchronously. The sector gear 326 can mesh with the racks 325. Figure 14As shown, the output gear 324 rotates clockwise. When the sector gear 326 meshes with the rack 325 on the right, the push rod 323 pushes the piston 322 downward. As the output gear 324 continues to rotate, the sector gear 326 will disengage from the rack 325 on the right and mesh with the rack 325 on the left. At this time, the push rod 323 pushes the piston 322 upward, and so on.

[0065] The cylinder body 321 is provided with an outlet 327 and an inlet 328. A third one-way valve 371 is located at the inlet 328. One end of the inlet pipe 36 is connected to the inlet 328, and the other end of the inlet pipe 36 passes through the upper shell 11 and is connected to the spray hole 312. The inlet seal 39 seals both the gap between the inlet pipe 36 and the outer shell (upper shell 11) and the gap between the inlet pipe 36 and the water tank 31. By setting the inlet seal 39 and the pump seal 3a, it can be ensured that the water entering and leaving the water tank 31 will not affect the waterproof sealing of the installation chamber 14, and the installation and removal of the water tank 31 will not affect it.

[0066] The inlet 328, in conjunction with the inlet pipe 36, limits the third check valve 371. The third check valve 371 is a back-pressure flexible check valve, restricting the inlet 328 to only supply water or air to the cylinder 321. The second check valve 372 is located at the outlet 327, which connects to the second end of the base tube 33. Ideally, the second end of the base tube 33 should be fitted with the outlet 327 to prevent the base tube 33 from loosening or even falling off. The outlet 327 and the second end of the base tube 33 cooperate to limit the second check valve 372. The second check valve 372 is also a back-pressure flexible check valve, restricting the flow of water or air from the cylinder 321 to only the outlet 327.

[0067] When the piston 322 moves away from the cylinder 321, the third check valve 371 opens and the second check valve 372 closes, allowing water or air in the water tank 31 to be drawn into the cylinder 321. When the piston 322 moves in the opposite direction, the third check valve 371 closes and the second check valve 372 opens, allowing water or air in the cylinder 321 to be discharged, thus achieving water spraying or air exhaust.

[0068] The first end of the rotating tube 34 is a water spray outlet, facing upwards and not vertically. A spray gun 341 can be added to the first end of the rotating tube 34. The second end of the rotating tube 34 passes through the through hole 113 and connects to the first end of the base tube 33. The second end of the rotating tube 34 is inserted into the first end of the base tube 33, and the rotating tube 34 can rotate relative to the base tube 33. A stepped surface is provided at the first end of the base tube 33 to limit the insertion depth of the rotating tube 34.

[0069] The first end of the base tube 33 is positioned near the through hole 113. The base tube 33 is fixed relative to the outer shell to prevent it from being pushed open when the rotating tube 34 is inserted, ensuring the stability of the connection and achieving a waterproof seal. Ribs can be installed inside the outer shell to clamp or support the base tube 33, and in conjunction with the connection between the pump assembly 32 and the base tube 33, the mounting groove 114 limits the position of the first end of the base tube 33, thus fixing the position of the base tube 33 relative to the outer shell. Of course, other methods can also be used, such as inserting, snapping, or screwing the base tube 33 to the outer shell, which will not be elaborated further.

[0070] The water spray seal 38 simultaneously seals the gaps between the base tube 33 and the outer shell (upper shell 11), the gaps between the rotating tube 34 and the outer shell (upper shell 11), and the gaps between the rotating tube 34 and the base tube 33. The base tube 33, in conjunction with the outer shell (upper shell 11), limits the position of the water spray seal 38, ensuring its stability. Specifically, the water spray seal 38 includes an outer tube 381, a connecting part 382, ​​and an inner tube 383 connected in sequence. The outer tube 381 and the inner tube 383 are coaxially arranged, and the inner tube 383 is located within the outer tube 381. There is a gap between the inner tube 383 and the outer tube 381, the width of which is adapted to the thickness of the sealing ring 331. The mounting groove 114 is provided on the inner surface of the outer shell (upper shell 11), and the through hole 113 is located at the bottom of the mounting groove 114. The shape of the mounting groove 114 is adapted to the outer shape of the outer tube 381. A sealing ring 331 is integrally formed at the first end of the base tube 33. The sealing ring 331 is fitted onto the base tube 33, and partially extends out of the base tube 33. The sealing ring 331 and the first end opening of the base tube 33 are coaxial. The connecting part 382 abuts against the port of the sealing ring 331 and the bottom of the mounting groove 114. The outer tube part 381 abuts against the outer wall of the sealing ring 331 and the groove wall of the mounting groove 114. The inner tube part 383 abuts against the inner wall of the sealing ring 331 and the outer wall of the second end of the rotating tube 34. Because the rotating tube 34 is designed to be pluggable, in order to further ensure the sealing between the rotating tube 34 and the base tube 33, the surface of the inner tube part 383 that abuts against the outer wall of the second end of the rotating tube 34 is provided with at least one raised edge 384. The water spray seal 38 is preferably made of silicone or rubber. During assembly, the water spray seal 38 can be first fitted onto the sealing ring 331, and then inserted into the mounting groove 114, thus completing the positioning and limiting of the water spray seal 38 and the positioning of the first end of the base tube 33, which is quick and convenient.

[0071] A rotating mechanism is used to drive the rotating tube 34 to rotate, enhancing the fun. The rotating mechanism includes a rotating drive assembly 41 and a turntable 42. The turntable 42 is rotatably connected to the outside of the housing, and the turntable 42 is limited and engaged with the housing to prevent it from easily falling off. The rotating tube 34 is limited and set on the turntable 42, so that the rotating tube 34 rotates synchronously with the turntable 42. A through hole is provided at the center of the turntable 42 for the second end of the rotating tube 34 to pass through. After passing through the through hole and the through hole 113, the second end of the rotating tube 34 is inserted into the first end of the base tube 33.

[0072] The rotary drive assembly 41 is installed inside the housing. The rotary drive assembly 41 can be a motor with a reducer. The rotary drive assembly 41 has an output shaft 43 that passes through the housing and is connected to the turntable 42. The output shaft 43 is sealed to the housing (upper shell 11) by a sealing plug or sealing ring. The housing (upper shell 11) has a groove that matches the shape of the sealing plug or sealing ring. The bottom of the groove and the middle of the sealing plug or sealing ring both have through holes that match the output shaft 43. By locking the rotary drive assembly 41, the sealing plug can be pressed tightly into the groove. A small gear 44 is provided at the end of the output shaft 43 extending out of the housing. A large gear 45 is provided on the turntable 42, rotating coaxially and synchronously with the turntable 42. The small gear 44 meshes with the large gear 45. By connecting the rotary drive assembly 41 to the toy car's controller, and by setting a corresponding control switch on the toy's remote control, the rotary drive assembly 41 can be remotely controlled, thereby achieving remote control of the water spray direction.

[0073] To enhance the fun of the toy car, a misting mechanism and at least one interactive component are provided. The misting mechanism draws water from the water tank 31.

[0074] The water tank 31 is also provided with an atomizing hole 318, which connects to the first chamber 316 or the deep water level zone. The atomizing mechanism includes an atomizing plate 51 and a water-absorbing component 52. The atomizing plate 51 is embedded in the atomizing hole 318 and is sealed to the atomizing hole 318 by a sealing gasket. The atomizing hole 318 can be designed as a stepped hole for easy installation. In addition, a breathable decorative cover 115 can be provided on the outside of the outer shell to press down the atomizing plate 51. The water-absorbing component 52 can be a cotton swab. One end of the water-absorbing component 52 abuts against the atomizing plate 51, and the other end of the water-absorbing component 52 extends into the first chamber 316 or the deep water level zone through the atomizing hole 318 and abuts against the bottom of the first chamber 316 or the deep water level zone to ensure that the water-absorbing component 52 can still reliably absorb water when the water level in the first chamber 316 or the deep water level zone is low. In addition, an elastic element 53 can be provided at the bottom of the water-absorbing element 52 to lift the water-absorbing element 52 upwards, ensuring that the water-absorbing element 52 reliably contacts the atomizing plate 51, thus ensuring the use and safety of the atomizing plate 51. When the water in the second chamber 317 is used up, due to the setting of the partition 315, a certain amount of water can still be retained in the first chamber 316 for spraying, or after the water in the shallow water area is used up, the remaining water in the deep water area can continue to be supplied to the atomizing plate 51, thus delaying the spraying function. The atomizing plate 51 is less likely to dry-burn, and the toy car can use a regular spray plate without protection, which is beneficial for product cost control.

[0075] Interactive components can be one or more of the following: light source (lamp), speaker, and sound and light device. For example, colored lights can be installed at the positions of spray gun 341 and atomizing plate 51, so that the freshly sprayed water and mist can display colors, creating a visually striking effect at night. Additionally, a speaker can be installed on turntable 42 to play shooting sounds in sync with the water spray rhythm. Of course, lights can also be installed on wheel 21.

[0076] The aforementioned interactive components, atomizing plate 51, etc., need to be installed outside the housing. In this case, a dedicated power supply channel is designed for these electrical components installed outside the housing. Specifically, a terminal seal 61 and a terminal assembly 62 are added. A connecting hole 116 is provided on the housing (upper shell 11), which connects to the mounting chamber 14. The terminal seal 61 and the terminal assembly 62 are placed in the mounting chamber 14. The terminal assembly 62 includes a circuit board 63 and at least one terminal interface 64. The terminal interface 64 is located on the same side of the circuit board 63. The circuit board 63 is detachably connected to the housing, and the terminal interface 64 is placed in the connecting hole 116. Preferably, the terminal interface 64 extends a certain distance out of the connecting hole 116 to facilitate connection. The terminal seal 61 is pressed between the circuit board 63 and the housing, and a through hole 65 is provided on the terminal seal 61 for the terminal interface 64 to pass through.

[0077] In this case, terminal interfaces 64 are arranged side-by-side on the circuit board 63, with the spacing between adjacent terminal interfaces 64 being as small as possible. All terminal interfaces 64 form an interface group, and the shape of the via 65 is adapted to the shape of the interface group. Preferably, the terminal interfaces 64 are female terminal interfaces 64 for easy connection. The terminal interface 64 has at least two pins, generally two, corresponding to the positive and negative terminals of the power supply respectively. The side of the circuit board 63 without terminal interfaces 64 is a printed circuit layer. The pins pass through the circuit board 63 and are soldered to the printed circuit layer. Full solder can seal the hole through which the pins pass through the circuit board 63, ensuring the waterproof performance between the terminal interface 64 and the circuit board 63. The printed circuit layer connects to the control circuit board. Of course, an adhesive can also be applied to the circuit board 63 to form a waterproof film to enhance the waterproof performance.

[0078] In this case, the circuit board 63 is secured to the outer casing (upper casing 11) by three locking screws arranged in a triangular pattern. The outer casing has blind holes corresponding to the locking screws, and these holes communicate with the mounting chamber 14. The locking screws pass through the circuit board 63 and the terminal seal 61 sequentially before being threaded into the blind holes. Tightening the locking screws ensures a secure installation of the terminal assembly 62 and the terminal seal 61, guaranteeing waterproofing and facilitating connection. Furthermore, the triangular arrangement of the three locking screws corresponds to the triangular arrangement of the blind holes. By aligning the blind holes, the terminal assembly 62 can be oriented relative to the outer casing, ensuring accurate wiring of functional components.

[0079] To facilitate installation and improve waterproof sealing, a limiting groove 66 is provided on the side of the terminal seal 61 that fits against the circuit board 63. The shape of the limiting groove 66 is adapted to the shape of the circuit board 63, allowing the circuit board 63 to be embedded in the limiting groove 66. Simultaneously, a limiting frame 117 adapted to the shape of the terminal seal is provided on the inner wall of the outer shell (upper shell 11). During installation, the circuit board 63 is first inserted into the limiting groove 66, and then both are inserted into the limiting frame 117. Tightening the locking screw completes the installation, which is convenient, quick, and accurately positioned. Furthermore, the terminal seal 61 is made of an elastic material, such as rubber or silicone. When the locking screw is tightened, the terminal seal 61 can be deformed to a certain extent, allowing it to fit well against the circuit board 63 and the outer shell, thus ensuring waterproof sealing performance.

[0080] 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.
