DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 8 As shown: an internal and external bidirectional waterproof power supply structure for wading toys, including a power supply compartment 6 with a battery as a power supply 601, the shell 1 of the wading toy is composed of an upper cover and a base, and the base has an outer concave cavity 101 formed at the bottom. The lateral size of the power supply compartment 6 matches the outer concave cavity, but the depth is slightly smaller than the outer concave cavity 101. When the power supply compartment 6 is accommodated in the outer concave cavity 101 from bottom to top by embedding, there will be a part of surplus space on the top side of the outer concave cavity 101 that can form a sandwich 111, a circuit The board 7 is fixed in the interlayer 111; the outer side of the outer concave cavity 101 is also connected to the switch body 3 with the travel switch 2, and the two are connected through each other's wiring openings I303 and II161. The wires of the circuit board 7 (not shown in the figure) are inserted upward from the wiring opening II161 of the outer concave cavity 101 to the wiring opening I303 of the switch body 3, thereby being connected to the circuit of the travel switch 2. The wading device 8 of the wading toy can press the travel switch 2 through the top head 801, thereby opening and closing the corresponding circuit structure.

[0029] Furthermore, the wading toy has two sets of the above-mentioned wading devices 8, namely a faucet water outlet device and a piston drainage device. Two travel switches 2 are symmetrically arranged on the left and right sides of the switch body 3. The faucet water outlet device and the piston drainage device match the corresponding travel switch 2 through their respective top heads 801, thereby realizing their own water outlet and drainage functions.

[0030] Furthermore, the base of the wading toy has a cover 102 at the bottom locked by fasteners, which is used to close the power supply compartment 6 and the outer concave cavity 101. Of course, in order to prevent water outside the toy from flowing into the power supply structure through the gap between the cover 102 and the shell 1, a large sink 141 containing a large sealing ring 151 is formed around the outer concave cavity 101, and the cover 102 is pressed against the large sealing ring 151 by its own protruding portion 112.

[0031] Furthermore, in order to prevent water inside the toy from seeping into the power structure from the connection between the outer cavity 101 and the switch body 3, the outer cavity 101 is also formed with a small sink 121 at the connection position for accommodating a small sealing ring 131, and the convex edge 304 formed at the bottom of the wiring opening Ⅰ303 of the switch body 3 is pressed against the small sealing ring 131.

[0032] Specifically, the switch body 3 is further formed with a plug-in column 301 , which is plugged into the upper cover of the housing 1 through the plug-in column 301 , and the convex edge portion 304 is pressed against the small sealing ring 131 of the outer concave cavity 101 of the base.

[0033] Furthermore, the travel switch 2 is also sealed by a key cap 4 to prevent water inside the toy from penetrating into the power supply structure from the travel switch 2. Figure 3 , Figure 5 , Figure 7 As shown, the key cap 4 has an outer edge 401. When the switch body 3 is inserted into the side cover 5 in the lateral position, the outer edge 401 of the key cap 4 can be clamped together with the side cover 5, so that the key cap 4 is fixed on the switch body 3 and the travel switch 2 is sealed. Of course, the outer edge 401 of the key cap 4 is also formed with an annular rib 402. When the switch body 3 and the side cover 5 are assembled, the two can enclose each other to form a limiting cavity 501, and the rib 402 is accommodated in the limiting cavity 501 to prevent the key cap 4 from loosening.

[0034] Furthermore, the switch body 3 is formed with a square lateral groove 302 on the side, and the travel switch 2 is directly placed in the lateral groove 302 and is pressed against the bottom plate 201 by the button cap 4 to achieve fixation. Of course, in the actual production process, some process problems may cause the travel switch 2 to have a gap when installed. Specifically, the travel switch 2 may become loose and cannot be tightly pressed by the button cap 4. Therefore, the inner four walls of the lateral groove 302 are also formed with at least one convex rib 312 with a notch. The contour enclosed between the convex ribs 312 matches the shape of the bottom plate 201 of the travel switch 2, so that the travel switch 2 can be limited. The existence of the convex rib 312 eliminates the gap between the bottom plate 201 and the button cap 4, so that the button cap 4 can tightly press against the other side of the bottom plate 201. Under the two-way clamping action of the button cap 4 and the convex rib 312, the travel switch 2 will always be fixed on the switch body 3.

[0035] How to use wading toys: turn the handle of the faucet water outlet device, or press the piston of the piston drainage device. The top of the two sets of devices can press the corresponding travel switch to realize the water outlet and drainage actions of the toy in an electrically controlled manner (the faucet water outlet device and the piston drainage device are the remaining parts of the wading toy, and this article will not go into details about their structure and principle).
