Technical Field

[0001] The utility model relates to the technical field of igniters, and particularly relates to a touch-type switch cap, an igniter and a household appliance. Background Art

[0002] An igniter is a device that can instantaneously provide sufficient energy to ignite fuels such as pulverized coal, oil, gas, etc. and stabilize the flame. In daily life, igniters are widely used, such as igniting various household appliances such as gas stoves, barbecue grills, water heaters, etc.

[0003] An igniter mainly relies on a battery to supply electric energy. Common igniters include structures such as an igniter body and a battery slot. The battery slot is prominently arranged on the igniter body and is sealed by a cap, and a button piece is often installed on the top of the cap. Users can achieve the ignition operation by pressing the button piece.

[0004] However, since the cap and the button piece are assembled, it is easy for the connection part to become loose, which affects the stability of the overall structure. Moreover, this assembly method also reduces the waterproof and dustproof capabilities of the igniter and affects the service life of the igniter. Summary of the Utility Model

[0028] The present utility model provides a touch-type switch cap 100.

[0029] Please refer to Figure 1 and Figure 2, in an embodiment of the present utility model, the touch-type switch cap 100 includes a cap body 1 and a switch assembly 2. The cap body 1 has a cavity 11. A partial structure of the top wall of the cap body 1 forms an elastic pressing portion 12, and the elastic pressing portion 12 can axially move along the cap body 1 under the action of an external force. The switch assembly 2 is accommodated in the cavity 11. The switch assembly 2 includes a microswitch 21 and a circuit board 22 electrically connected to the microswitch 21. The microswitch 21 is located between the elastic pressing portion 12 and the circuit board 22. During the movement of the pressing portion, the microswitch 21 can be triggered by the pressing portion.

[0030] In the touch-type switch cap 100 of the solution of the present utility model, by providing the elastic pressing portion 12 integrally formed with the cap body 1 on the cap body 1, the connection and assembly relationship between the cap body 1 and the button piece in the original switch cap is cancelled, the number of components is reduced, the overall structure is made more concise, the production cost and assembly complexity are reduced. It can not only eliminate the risk of structural instability caused by loose connection or improper assembly, but also better prevent external substances such as moisture and dust from entering the cap body 1, so as to enhance the overall waterproof and dustproof capabilities. When the user needs to perform an ignition operation, the user can directly operate by pressing the top of the cap body 1, without a complex mechanical linkage structure, so that the microswitch 21 can be quickly triggered when subjected to an external force, improving the product performance of the switch cap.

[0031] In an embodiment of the present application, the touch-type switch cap 100 further includes a waterproof silicone pad. The waterproof silicone pad is accommodated in the cavity 11 and is located between the elastic pressing portion 12 and the microswitch 21. On the one hand, the waterproof silicone pad fills the gap between the elastic pressing portion 12 and the microswitch 21, ensuring that when the pressing portion moves, the normal operation of the switch will not be affected by the intrusion of external substances, and the waterproof silicone pad can provide a softer touch, making the user feel more comfortable during operation and improving the user experience. On the other hand, the waterproof silicone pad can also provide an additional waterproof barrier and dustproof barrier for the switch cap, effectively preventing moisture and dust from penetrating into the switch assembly 2, thereby protecting the internal circuit from damage.

[0032] In an embodiment of the present application, the side wall of the cavity 11 is provided with screw threads; the touch-type switch cap 100 further includes an external thread nut 3, and the external thread nut 3 is fixedly arranged in the cavity 11 through the screw threads, and the external thread nut 3 is located on the side of the circuit board 22 away from the micro switch 21. Through the structure of the screw threads and the external thread nut 3, the circuit board 22 can be more firmly fixed in the switch cap, ensuring that the circuit board 22 will not move due to external force or vibration, thereby improving the overall stability and reliability of the switch. And when the circuit board 22 needs to be replaced or maintained, only the nut needs to be unscrewed, which simplifies the assembly and maintenance process. In addition, the external thread nut 3 can also make the switch cap adapt to circuit boards 22 of different thicknesses. By adjusting the tightening degree of the external thread nut 3, circuit boards 22 of different specifications can be adapted, increasing the flexibility of the design.

[0033] In an embodiment of the present application, the waterproof silicone pad, the micro switch 21, and the circuit board 22 are all locked in the cavity 11 through the external thread nut 3. The fastening function of the external thread nut 3 can ensure that the waterproof silicone pad, the micro switch 21, and the circuit board 22 remain stable inside the switch cap, reducing the displacement of components caused by vibration or impact, and contributing to improving the overall reliability and service life of the product.

[0034] In an embodiment of the present application, the cap body 1 further forms a guiding portion 13, the guiding portion 13 is accommodated in the cavity 11 and is connected to the elastic pressing portion 12, and the elastic pressing portion 12 contacts the micro switch 21 through the guiding portion 13. On the one hand, the setting of the guiding portion 13 can ensure that the elastic pressing portion 12 can accurately trigger the micro switch 21 when pressed, thereby improving the response accuracy and reliability of the switch; on the other hand, the guiding portion 13 can also reduce the pressing stroke of the user, can shorten the operation time, and improve work efficiency, especially in application scenarios that require quick operation.

[0035] In an embodiment of the present application, the guiding portion 13 is a hollow cylindrical structure, one end of the guiding portion 13 is connected to the elastic pressing portion 12, and the other end of the guiding portion 13 is used to contact the micro switch 21. The hollow cylindrical structure can provide sufficient strength to support the contact between the elastic pressing portion 12 and the micro switch 21, ensuring the stability and durability of the structure under frequent operation. And compared with a solid structure, it can also save materials and reduce production costs.

[0036] In an embodiment of the present application, a part of the outer side wall of the elastic pressing portion 12 is convexly provided. The convex design can facilitate the user to identify the accurate position of the elastic pressing portion 12, and the user can quickly locate and operate the switch by touching the convex part.

[0037] In an embodiment of the present application, an anti-slip convex structure 14 is formed on the outer sidewall of the cap body 1. The anti-slip convex structure 14 can increase the holding stability of the switch cap during user operation, helping the user to grasp the switch cap more accurately and stably, and avoiding operation errors.

[0038] It should be noted that the material of the cap body can be any material convenient for integral molding, which can be metal or plastic. The present utility model does not make specific limitations thereto. Compared with the cap body cover made of metal material, the cap body made of plastic material has less influence on the conductive path and can avoid the external metal structure from damaging the conductive path. Therefore, in an embodiment of the present utility model, plastic is preferably used as the material of the cap body.
