Description

Technical Field

[0001] The utility model relates to the technical field of switches, and in particular to a waterproof light-touch switch. Background Art

[0002] A waterproof touch switch is a switch that can be immersed in water or rain without malfunctioning. It can also provide complete protection against dust in the air, ensuring that electronic equipment can operate normally in humid or watery environments, avoiding equipment damage and repair costs caused by water intrusion, thereby saving users a lot of money. Therefore, it is widely used in humid environments such as bathrooms and kitchens, audio-visual products, digital products, communication products, and computer products.

[0003] A Chinese patent discloses a new waterproof touch switch with the publication number CN209591860U. The article proposes that "it includes a cover plate, a button, a spring, a terminal, and a base. The cover plate covers the upper surface of the base and forms a cavity therebetween. The spring is arranged in the cavity. The terminal is embedded in the base. One end of the terminal is exposed in the cavity and is located under the spring, and the other end of the terminal is located outside the base. A button hole for the button to pass through is provided on the upper surface of the cover plate. The button is located in the button hole. The bottom of the button abuts against the spring and the outer ring is provided with dustproof glue. The button and the dustproof glue are integrally processed and formed. The utility model integrates the button and the dustproof glue into one piece, which improves production efficiency while preventing dust, water, etc. from entering the exposed part of the terminal in the base, thereby affecting the work efficiency, life and safety of the product. It has the advantages of simple structure, reasonable design, strong waterproof and dustproof performance, etc."

[0004] However, the sealing performance of the above solution is poor. A single waterproof sealing gasket is often used to seal the button and the base, which makes the sealing structure relatively simple. Moreover, after the button is pressed for a long time, the sealing performance of this part will be reduced, resulting in a decrease in the waterproof performance of the switch itself. Therefore, it is necessary to design a waterproof touch switch. Utility Model Content

[0005] The purpose of the utility model is to provide a waterproof touch switch, which solves the problem in the related art that the sealing of the switch itself will be affected after the button is pressed for a long time during use.

[0006] The technical solution of the utility model is as follows:

[0007] A waterproof touch switch includes a base; a reserved groove formed at equal angles on the surface of the base; a clamping block fixedly connected to the upper end of the inner wall of the reserved groove; an electrode sheet fixedly connected to the base; a metal spring fixedly connected to the inner bottom wall of the base; a cover plate engaged with the top end of the base; buckles fixedly connected to the four sides of the cover plate at equal angles; a button movably connected to the middle position of the cover plate; and a waterproof sealing gasket fixedly connected to the lower end of the button surface.

[0008] Preferably, a sealing assembly is provided on the cover plate and the base, and the sealing assembly is used to improve the sealing between the button, the cover plate and the base. The sealing assembly includes: a sealing groove annularly opened at the top of the base; a sealing ring annularly fixedly connected to the bottom end of the waterproof sealing gasket; a positioning groove annularly opened at the top of the waterproof sealing gasket; and a positioning rubber ring annularly fixedly connected to the inner top wall of the cover plate.

[0009] Preferably, a snap-fit structure is formed between the sealing ring and the inner wall of the sealing groove, and friction lines are formed on the surfaces of the sealing groove and the sealing ring.

[0010] Preferably, a snap-fit structure is formed between the positioning rubber ring and the interior of the positioning groove, and the lower ends of the cross sections of the positioning groove and the positioning rubber ring are isosceles trapezoidal.

[0011] Preferably, a snap-fit structure is formed between the clamping block and the inside of the buckle, and the top end of the clamping block and the bottom end of the buckle are beveled.

[0012] Preferably, an elastic piece is fixedly connected to the inner wall of the reserved groove, one side of the top end of the elastic piece is a bevel, and the cross-section of the elastic piece is L-shaped.

[0013] Preferably, anti-slip grooves are provided at equal intervals on one side of the elastic sheet, and the cross-section of the anti-slip grooves is in the shape of an isosceles trapezoid.

[0014] Preferably, a groove is provided at the top of the button, and the groove is funnel-shaped.

[0015] Beneficial effects of the utility model:

[0016] 1. Through the provided positioning groove, cover plate, sealing ring, sealing groove, waterproof sealing gasket and positioning rubber ring, after the cover plate and the base are clamped and installed, the periphery of the waterproof sealing gasket will be compressed and deformed, thereby improving the seal between the cover plate and the base. At the same time, the sealing ring is clamped into the sealing groove, so that the bottom end of the waterproof sealing gasket is tightly fitted with the top end of the base, thereby improving the clamping and installation tightness and sealing between the waterproof sealing gasket and the base. In addition, the positioning rubber ring is clamped into the positioning groove, thereby improving the clamping tightness and sealing between the cover plate and the waterproof sealing gasket. Thus, the sealing effect of the switch body can be improved through multiple seals, thereby avoiding the reduction of sealing caused by long-term pressing of the button and improving its practicality.

[0017] 2. By setting the card block, reserved groove, elastic sheet and buckle, the buckle is engaged with the inside of the card block to achieve the snap-on installation between the cover and the base. At the same time, when the buckle is engaged with the card block, the elastic sheet will be deformed. At this time, the isosceles trapezoidal anti-slip pattern is used to improve the anti-slip tightness of the engagement between the two sides of the buckle and the inner wall of the reserved groove, thereby further improving the tightness of the engagement between the cover and the base, avoiding the loosening and separation of the two during use, and improving its practicality.
