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 7 As shown: a waterproof switch mechanism for a wading toy, including two travel switches 2, a switch body 3 is plugged into a housing 1 of the wading toy through a plug-in column 301, and the two travel switches 2 are symmetrically arranged on both sides of the switch body 3. The wading toy has two sets of wading devices 8, namely a faucet water outlet device and a piston drainage device. Its housing is composed of an upper cover and a base. The two sets of wading devices 8 arranged on the upper cover press the corresponding travel switch 2 through a top head 801, thereby realizing their own water outlet and drainage functions.

[0029] Furthermore, the travel switch 2 is sealed by a key cap 4 to achieve a waterproof function of the switch. Figure 3-Figure 4 , Figure 6 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.

[0030] 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 a gap in the travel switch 2 during installation. 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 by 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 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.

[0031] Further, such as Figure 2-Figure 3 As shown, the switch body 3 and the outer concave cavity 101 of the base of the housing 1 for installing the power supply 601 and the circuit board 7 are connected to each other, and are connected through each other's wiring openings I303 and II141. The wires of the circuit board 7 (not shown in the figure) are passed upward from the wiring opening II141 of the outer concave cavity 101 into the wiring opening I303 of the switch body 3, and then connected to the travel switch 2 provided on the switch body 3 to realize the corresponding electric control function.

[0032] Specifically, a power supply compartment 6 for installing a power supply 601 is embedded in the outer concave cavity 101 of the shell 1. The lateral size of the power supply compartment 6 matches the outer concave cavity 101, but the depth is slightly smaller than the outer concave cavity 101. When the power supply compartment 6 is fixed in the outer concave cavity 101, the surplus space on the top of the outer concave cavity 101 forms a sandwich 111, and the circuit board 7 is installed in the sandwich 111. Since the function of the power supply compartment 6 is to install the power supply, the shell 1 will inevitably design a corresponding waterproof structure for it, such as Figure 3 The large sealing ring 112 above the cover plate 102 is a waterproof structure that can prevent water from penetrating into the circuit structure from the outside of the toy and causing damage to the circuit.

[0033] Furthermore, in order to prevent water from seeping into the connection between the outer cavity 101 and the switch body 3, the outer cavity 101 also forms a recess 121 with a small sealing ring 131 installed at the position of its own wiring opening II 141, and the convex edge 304 formed by the wiring opening I 303 of the switch body 3 presses against the small sealing ring 131.

[0034] 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).

[0035] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
