Description

Technical Field

[0001] This utility model relates to the field of push button switch technology, specifically to a waterproof and air-leaking foot-operated push button switch. Background Technology

[0002] Foot-operated push-button switches are widely used in humid or moisture-laden environments such as bathrooms, kitchens, and industrial workshops due to their convenient operation. These environments place stringent requirements on the waterproof performance and dynamic operational reliability of the switches.

[0003] Currently, similar foot-operated push-button switches on the market have significant shortcomings in their waterproof structural design. The core issues lie in the dynamic waterproof reliability of the switch button and the coordination between the seal and breathability of the silicone sleeve at the tail. In terms of button waterproofing design, existing products mostly rely on the interference fit between the waterproof ring and the mating components to achieve a seal. However, this method has a significant drawback: when the button is pressed and rebounds, a momentary negative pressure can easily form inside the switch, drawing in external moisture and causing the internal circuitry to become damp and short-circuit, affecting its lifespan and even posing a safety hazard.

[0004] Meanwhile, existing silicone sleeves at the tail of switches generally cannot simultaneously provide waterproofing and breathability. If the silicone sleeve is too tight, the internal air pressure will increase sharply when the button is pressed, and the button may be "sucked" in by atmospheric pressure and unable to rebound properly. If the sealing is reduced to ensure rebound performance, or if the waterproof ring is not pressed tightly, external moisture may be easily drawn back into the switch when the button rebounds, making the waterproofing effect highly uncertain.

[0005] As market demands for switch performance continue to rise, existing foot-kick push-button switches that rely on interference fit for waterproofing and traditional silicone sleeve structures can no longer meet the requirements for long-term stable dynamic waterproofing and operational reliability in humid environments. There is an urgent need to optimize and improve the waterproof structure and silicone sleeve design of the switches to address these technical challenges. Utility Model Content

[0006] To address the shortcomings of the prior art, this utility model provides a waterproof and air-leaking foot-operated push button switch.

[0007] The technical solution adopted by this utility model is: a waterproof and air-leaking foot-kick type button switch, including a silicone sleeve with an opening at the top and an outer shell sleeve fitted on the opening of the silicone sleeve, and a base, a top cover, a button base and a button connected to the button base arranged sequentially from bottom to top inside the outer shell sleeve. The bottom wall of the silicone sleeve is provided with a wire outlet hole for the wire to extend out. The wire outlet hole is fitted to the outer wall of the wire, and the wire outlet hole includes a large diameter hole on the inner side and a small diameter hole on the outer side. The large diameter hole and the small diameter hole are transitioned by a bevel or a rounded arc. The thickness of the bottom wall of the silicone sleeve is greater than the thickness of the side wall of the silicone sleeve.

[0008] Furthermore, a chamfer is provided on the inner side of the large-diameter hole.

[0009] Furthermore, a raised ring is provided on the outer wall of the silicone sleeve.

[0010] Furthermore, the diameter of the small-diameter hole is 65%–85% of the diameter of the large-diameter hole.

[0011] Furthermore, the diameter of the small-diameter hole is 3-4 mm, and the diameter of the large-diameter hole is 4-5 mm.

[0012] Furthermore, the thickness of the bottom wall of the silicone sleeve is 1-3 times the thickness of the side wall of the silicone sleeve.

[0013] This invention solves the problems of unreliable dynamic waterproofing, rebound jamming, and the contradiction between sealing and breathability in existing foot-operated push-button switches by optimizing the silicone sleeve structure. The core beneficial effects are as follows: 1. Dynamic waterproofing for enhanced reliability: The silicone sleeve's bottom wall features a layered design with "large-diameter hole + small-diameter hole + transition surface" to create a thickened bottom wall that tightly adheres to the wires, preventing liquid water and moisture from entering. When dynamically pressed and rebounded, it avoids internal negative pressure that could cause moisture to be drawn back, eliminating the risk of short circuits due to moisture and improving service life and safety in humid environments (bathrooms, workshops, etc.).

[0014] 2. Dual protection of breathability and rebound: The thickened bottom wall and layered holes work together to allow air to escape when pressed, avoiding a sudden increase in internal air pressure; when rebounding, the thinner part of the bottom wall remains open to balance the air pressure, solving the contradiction of "too tight a seal causing jamming and no rebound" and "insufficient seal causing waterproof failure", improving the smoothness and reliability of operation.

[0015] 3. Excellent compatibility and economy: The improvement is only for the silicone sleeve, without the need to modify other components such as the outer shell and base, and it is compatible with existing production processes, reducing R&D and manufacturing costs.

[0016] 4. Enhanced core competitiveness: Overcoming key pain points such as dynamic waterproofing and rebound jamming, the core performance far exceeds that of existing products, meeting the market's upgrade demand for high-quality switches and helping enterprises enhance their market competitiveness.

[0017] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0025] This utility model provides a waterproof and air-leaking kick-type push button switch.

[0026] In this embodiment, refer to Figure 1-3 The waterproof and air-leaking foot-operated push button switch includes a silicone sleeve 2 with an upper opening 1 and an outer shell 3 fitted onto the opening of the silicone sleeve 2, as well as a base 4, an upper cover 5, a button base 6, and a button 7 connected to the button base, arranged sequentially from bottom to top inside the outer shell. The bottom wall of the silicone sleeve is provided with a wire outlet hole 9 for the wire 8 to extend out. The wire outlet hole 9 is fitted to the outer wall of the wire, and the wire outlet hole includes a large diameter hole 10 located on the inner side and a small diameter hole 11 located on the outer side. The large diameter hole and the small diameter hole are transitioned by a bevel or a rounded arc. The thickness of the bottom wall of the silicone sleeve is greater than the thickness of the side wall of the silicone sleeve.

[0027] In the above technical solution, the bottom of the silicone sleeve is thick enough, and the cable outlet is designed in layers (with "inner large diameter hole + outer small diameter hole + bevel / arc transition" layered cable outlet). When the silicone sleeve inflates, the air escapes from the thinner part at the bottom. When the silicone sleeve is squeezed, because it is thick enough, the larger holes will not be squeezed, and the thinner parts will automatically open to expel the air. During the process of the silicone sleeve recovering, because the holes in the thinner parts are still open, air will slowly enter until it returns to its original state. The cable outlet at the tail will then be tightly closed with the wire, thus forming a structure that is both waterproof and airtight. The function of the wire is to connect different functional terminals according to customer needs, and then connect to external devices.

[0028] This completely solves the problem of moisture backflow caused by internal negative pressure when traditional switches are pressed and rebounded, eliminates the risk of short circuits due to moisture, and makes the switch suitable for use in humid environments such as bathrooms and industrial workshops.

[0029] Specifically, a chamfer 12 is provided on the inner side of the large-diameter hole.

[0030] In this embodiment, the chamfered corners provide a guiding effect, making the wire threading process smoother, reducing assembly difficulty, improving production efficiency, and reducing the breakage rate during wire threading. Specifically, a raised ring 13 is provided on the outer wall of the silicone sleeve.

[0031] A raised ring is provided on the outer wall of the silicone sleeve to increase the strength of the middle part of the silicone sleeve, and at the same time, it can be pre-tightened when installed with the outer sleeve.

[0032] Specifically, the diameter of the small-diameter hole is 65%–85% of the diameter of the large-diameter hole; the diameter of the small-diameter hole is 3-4 mm, and the diameter of the large-diameter hole is 4-5 mm; the thickness of the bottom wall of the silicone sleeve is 1-3 times the thickness of the side wall of the silicone sleeve.

[0033] By using appropriately sized orifices and silicone sleeves, the bottom wall of the silicone sleeve can possess sufficient elastic deformation capacity to achieve the exhaust / intake function while ensuring strength. This also avoids the problems of insufficient overall elasticity due to an excessively thick bottom wall or insufficient strength due to an excessively thin bottom wall.

[0034] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
