[0028] Protective sleeve 10, body 100, inner cavity 101, opening 102, guide part 110, outer wall surface 111, inner wall surface 112, accommodating part 120, sealing part 130, marking part 140. Detailed Implementation

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0030] An igniter typically consists of a cover and a main body. The cover is exposed and serves as the button for user operation; the main body acts as the ignition switch and is connected to the cover. Pressing the cover triggers the ignition switch, thus igniting the ignition. To prevent water from entering through the gap between the cover and the main body and causing a short circuit in the ignition switch, a waterproof protective cover is usually installed.

[0031] In one related technology, a silicone sleeve is installed on the ignition button base, but the silicone sleeve only covers a portion of the button base, resulting in limited waterproofing. In another related technology, the ignition button area is covered with a waterproof sleeve, but due to the limitations of the waterproof sleeve's structure, water can seep along the outer surface of the sleeve into the gap between the button and the ignition switch, causing a short circuit.

[0032] To solve the above-mentioned technical problems, this application provides a protective cover 10, the body 100 of which is designed with a guide portion 110. The guide portion 110 can guide water and oil stains that drip onto the surface of the body 100 in a direction away from the body 100, thereby effectively preventing water and oil stains from penetrating into the protected part and significantly improving the waterproof and oil-proof performance of the protective cover 10.

[0033] The following is for reference Figures 1 to 3 The protective sleeve 10 of the present application embodiment will be described in detail.

[0034] like Figure 1 , Figure 2 and combined Figure 3As shown, the protective sleeve 10 of this application embodiment includes a body 100, the body 100 defining an inner cavity 101 and an opening 102 communicating with the inner cavity 101, the inner cavity 101 being used to accommodate at least a portion of the protected component; the body 100 has a first end and a second end disposed opposite to each other in the longitudinal direction, the opening 102 being disposed at the first end of the body 100; wherein, the body 100 has a guide portion 110, the outer wall surface 111 of the guide portion 110 extending obliquely in a direction away from the longitudinal axis of the body 100 in the direction toward the first end.

[0035] like Figure 3 As shown, the lower end of the body 100 is the first end, the upper end of the body 100 is the second end, and the longitudinal axis of the body 100 is L.

[0036] The shape and size of the body 100 can be adjusted according to the shape and size of the matched protected part, and this application embodiment does not specifically limit this.

[0037] The protected component can be an igniter for kitchen appliances such as fryers, ovens, and gas stoves, or an electronic accessory such as a thermostat or control knob. This is merely an example and does not constitute a limitation of this application.

[0038] In this embodiment, the guide portion 110 of the body 100 can guide water and oil stains away from the longitudinal axis of the body 100, that is, guide water and oil stains away from the opening 102 / inner cavity 101 of the body 100, so as to prevent water and oil stains from penetrating into the protected part, thereby improving the waterproof and oil-proof effect.

[0039] In one embodiment, the inner cavity 101 of the body 100 can be used to accommodate a portion of the protected part. For example, the inner cavity 101 of the body 100 can only accommodate the area of ​​the protected part that is close to the waterproof part, while the area that is far from the waterproof part can be exposed to the outside. This design can also effectively protect the waterproof part of the protected part.

[0040] In another embodiment, the inner cavity 101 of the body 100 can be used to accommodate the entire area of ​​the protected component, thereby providing comprehensive protection for the protected component, improving the waterproof effect, and enhancing the durability of the protected component.

[0041] In one embodiment, the angle α between the extending direction of the outer wall surface 111 of the guide portion 110 and the longitudinal axis of the body 100 satisfies: 0 < α < 90°, so as to ensure the guiding effect of the guide portion 110 on water and oil.

[0042] For example, 20°≤α≤40°, such as α can be 20°, 25°, 27°, 30°, 35°, 40°, etc. This is just an example and does not constitute a limitation on this application. Those skilled in the art will understand that the value of α can be determined in combination with the shape of the protected part and the flow guiding effect.

[0043] In one embodiment, the flow guide 110 defines a portion of the space within the cavity 101, and the inner wall surface 112 of the flow guide 110 extends obliquely in a direction away from the longitudinal axis of the body 100 in the direction toward the first end. That is, the portion of space defined by the flow guide 110 has a gradually expanding structure in the direction toward the first end. This design not only increases the volume of this portion of space but also accommodates protected components of different sizes, thereby improving the compatibility and applicability of the protective sleeve 10.

[0044] For example, the inner wall surface 112 of the flow guide 110 extends obliquely toward the first end in a direction parallel to the outer wall surface 111 of the flow guide 110 extends obliquely toward the first end in a direction, thereby forming a regular conical structure that is convenient for processing and manufacturing.

[0045] In one embodiment, the first end of the body 100 has a sealing portion 130, which is formed by extending the guide portion 110 from the edge adjacent to the first end along the longitudinal axis toward the body 100, and an opening 102 is formed in the sealing portion 130. The sealing portion 130 can effectively seal the gap between the covered area of ​​the protected component and the area requiring waterproofing, thereby further improving the waterproof performance of the protective sleeve 10. At the same time, the sealing portion 130 can also limit the position of the protected component in the inner cavity 101 of the body 100, preventing it from detaching from the inner cavity 101 and ensuring stability.

[0046] For example, such as Figure 3 As shown, the first end of the body 100 extends horizontally, that is, the sealing part 130 and the opening 102 of the body 100 both extend horizontally. The angle between the plane where the sealing part 130 is located and the plane where the guide part 110 is located is the complementary angle β of α, where β satisfies: 0 < β < 90°. For example, 50° ≤ β ≤ 70°. For example, β can be 50°, 55°, 60°, 63°, 70°, etc. This is only an example and does not constitute a limitation of this application.

[0047] In one embodiment, the protective cover 10 is made of silicone or rubber, and the inner diameter of the opening 102 is less than or equal to the outer diameter of the protected part. The softness of silicone and rubber materials allows the protective cover 10 to adapt to protected parts of different shapes and sizes; even if the opening 102 is slightly small, installation can be achieved through the material's ductility. The inner diameter of the opening 102 being less than or equal to the outer diameter of the protected part allows for a tight fit during installation, improving waterproofing and preventing dust or other impurities from entering through the opening 102, thereby enhancing the protective effect of the protective cover 10.

[0048] In one embodiment, the body 100 further includes a receiving portion 120, at least a portion of which is formed by a longitudinally extending edge of the flow guide portion 110 away from the first end. The receiving portion 120 and the flow guide portion 110 together define an inner cavity 101 to increase the size of the inner cavity 101 and provide a variety of inner cavity 101 structural designs, further improving the compatibility and applicability of the protective sleeve 10.

[0049] For example, the receiving portion 120 includes an arcuate portion and a cylindrical portion extending longitudinally, with the cylindrical portion located between the arcuate portion and the guide portion 110. This design, on the one hand, increases the space of the inner cavity 101, enabling the protective cover 10 to adapt to more types of protected components and increasing the versatility of the protective cover 10; on the other hand, the combination of the arcuate and cylindrical shapes makes the appearance of the protective cover 10 more streamlined, enhancing its visual appeal.

[0050] Understandably, in embodiments where the body 100 includes a receiving portion 120, the end of the receiving portion 120 that is away from the guide portion 110 is the second end of the body 100.

[0051] The receiving part 120 and the guiding part 110 can be integrally molded to reduce production replicability and cost, while eliminating seams and reducing potential leakage points, thereby improving the waterproof effect.

[0052] In one embodiment, the wall thickness of the body 100 is greater than or equal to 1 mm and less than or equal to 5 mm. This thickness design ensures the durability of the protective cover 10, preventing deformation or damage, while also providing a good feel when the user presses, avoiding the impact on the pressing effect due to excessive thickness of the protective cover 10.

[0053] For example, the wall thickness b of the body 100 can be 1mm, 1.5mm, 2mm, 2.5mm, etc. This is just an example and does not constitute a limitation on this application.

[0054] In one embodiment, the body 100 further includes an identification part 140, which is disposed on the outer wall surface of the second end of the body 100 for reminding the user.

[0055] For example, such as Figure 1 As shown, the marking part 140 protrudes from the second end of the body 100, that is, the marking part 140 can be a three-dimensional structure with a certain thickness to enhance the marking function.

[0056] The shape of the marking section 140 can be flexibly set according to the type of the protected component, for example, Figure 1 As shown, when the protected component is an igniter, the marking part 140 can adopt a polygonal radial shape similar to a star outline to highlight the marking of the ignition function.

[0057] According to another aspect of the embodiments of this application, this application also provides an ignition device, which includes an igniter and a protective sleeve 10 of any of the above embodiments. The igniter includes a cover, and the protective sleeve 10 can cover at least a portion of the outer side of the cover. That is, at least a portion of the cover is accommodated within the inner cavity 101 of the protective sleeve 10 and is covered by the protective sleeve 10.

[0058] In this embodiment, the guide portion 110 of the protective sleeve 10 can guide water and oil stains away from the opening 102 / inner cavity 101 of the body 100, thereby preventing water and oil stains from seeping into the igniter and improving the waterproof and oil-proof effect.

[0059] In one embodiment, the body 100 of the protective sleeve 10 covers the entire structure of the cover, and the inner walls of the first and second ends of the body 100 abut against the two ends of the cover, respectively. This design can, on the one hand, increase the limiting effect on the cover and prevent the cover from detaching from the protective sleeve 10; on the other hand, when the user presses the second end of the body 100, they can quickly feel the cover, thereby improving the pressing feel and operating experience.

[0060] The igniter also includes a main body, with a cover movably mounted on the main body. The sealing part 130 of the protective sleeve 10 is located between the main body and the cover, used to seal the gap between the main body and the cover, enhance the sealing effect, effectively prevent water and oil from seeping in through the gap, thereby improving the waterproof protection performance of the main body.

[0061] Understandably, the cover and the main body, which serves as the ignition switch, are movably connected, for example, by a spring connecting the cover and the main body. Pressing the cover triggers the ignition switch. Once triggered, the internal circuit closes, creating a current path. The current flows through the high-voltage module inside the igniter, generating a high-voltage arc or spark. This spark ignites the gas at the gas outlet, thus achieving ignition. Since the structure and principle of the igniter are well-known to those skilled in the art, they will not be elaborated upon here.

[0062] According to another aspect of the embodiments of this application, the embodiments of this application also provide a gas appliance, including a protective cover 10 of any of the foregoing embodiments and an ignition device of any of the foregoing embodiments.

[0063] Gas appliances can be fryers, ovens, gas stoves, etc., which are merely examples and do not constitute a limitation of this application.

[0064] The gas appliance includes a control panel, with the igniter cover located on the outside of the control panel for user operation, and the igniter body 100 installed on the inside of the control panel and connected to the cover via mounting holes in the control panel.

[0065] In one embodiment, the igniter cover can be vertically mounted on the upper side of the panel, and correspondingly, the protective sleeve 10 vertically covers the outside of the cover.

[0066] In another embodiment, the igniter cover can be horizontally positioned on the front side of the panel, and correspondingly, the protective sleeve 10 is horizontally covering the outside of the cover.

[0067] The igniter and protective cover 10 can be positioned in other ways, the above are just examples and do not constitute a limitation of this application.
