Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a waterproof structure for a rotary switch. Background Technology

[0002] In the daily use of electric heating pots, the knob switch, as a key component for controlling core functions such as heating temperature and time, operates in a significantly humid environment. During cooking, a large amount of moisture is easily generated around the pot, and soup or water stains may splash onto the knob switch surface due to improper operation, or even seep in through the gap between the switch and the pot panel.

[0003] Traditional electric heating pots often lack a reliable seal between the knob switch and the casing, allowing moisture and liquids to easily penetrate the switch, leading to malfunctions, poor contact, and affecting the precision of cooking. While some electric heating pots attempt to add simple seals to the knob, the sealing structure design is often inadequate. In pursuit of waterproofing, some sealing structures fit the knob too tightly, significantly increasing the torque required to turn it. Users will find it difficult to turn, or even unable to turn it at all, severely impacting the smoothness of operation.

[0004] Based on the above, this utility model proposes a waterproof structure for a rotary switch, which can effectively solve the above problems. Utility Model Content

[0005] This utility model addresses the shortcomings of the existing technology by providing a waterproof structure for a rotary switch.

[0006] This utility model is achieved through the following technical solution:

[0007] A waterproof structure for a rotary switch includes a housing, a knob body, and waterproof silicone. The housing has a panel on its top and a sidewall extending upwards and passing through the panel. The waterproof silicone is disposed between the housing and the panel. The knob body includes an outer ring and a transparent disc. The outer ring and the transparent disc are hooked together. An outer ring wall is provided on the outer side of the outer ring. Multiple first hooks are evenly distributed at equal angles inside the outer ring. The waterproof silicone and the housing sidewall are fitted between the outer ring wall and the first hooks, and the outer ring wall is sealed to the waterproof silicone. The first hooks are hooked together with the inner side of the housing sidewall.

[0008] According to the above technical solution, as a further preferred technical solution, the top inner side of the waterproof silicone has an annular notch, and the top outer side of the waterproof silicone is provided with a sealing rib, which abuts against the outer ring wall.

[0009] According to the above technical solution, as a further preferred technical solution, the inner side of the housing sidewall is provided with a ring edge that engages with and connects to the first hook.

[0010] According to the above technical solution, as a further preferred technical solution, the bottom of the transparent disc is fixedly connected with a plurality of second hooks that are evenly distributed at equal angles.

[0011] According to the above technical solution, as a further preferred technical solution, the outer ring of the knob is provided with an inner ring wall for connecting two adjacent first hooks, and the inner ring wall is hooked and connected to the second hook.

[0012] According to the above technical solution, as a further preferred technical solution, an annular groove is formed on the outer periphery of the transparent disk, and an O-ring is installed in the annular groove.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0014] This invention provides a waterproof structure for a rotary switch. By placing waterproof silicone between the housing and the panel, and fitting the waterproof silicone and the housing sidewall between the outer ring wall of the knob and a first hook, the structure effectively prevents water from entering the rotary switch through gaps, significantly improving its waterproof performance. Furthermore, by creating an annular notch at the top of the waterproof silicone, a seal is formed between the silicone, the housing sidewall, and the knob when the knob is not rotating. When the knob rotates, the silicone is compressed and deformed to the annular notch, reducing the compressive rebound force between the silicone and the knob, thus decreasing friction. The seal between the silicone and the knob remains intact, maintaining waterproofing without affecting the knob's rotational torque. Attached Figure Description

[0021] A waterproof structure for a rotary switch includes a housing 1, a knob body 2, and waterproof silicone 3. The housing 1 has a panel 4 on its top and a side wall 5 extending upwards and passing through the panel 4. The waterproof silicone 3 is disposed between the housing 1 and the panel 4. The knob body 2 includes a knob outer ring 6 and a transparent disc 7. The knob outer ring 6 and the transparent disc 7 are hooked together. The outer ring 6 has an outer ring wall 8 on its outer side, and multiple first hooks 9 evenly distributed at equal angles inside the knob outer ring 6. The waterproof silicone 3 and the housing side wall 5 are fitted between the outer ring wall 8 and the first hooks 9, and the outer ring wall 8 and the waterproof silicone 3 are sealed together. The first hooks 9 are hooked together with the inner side of the housing side wall 5.

[0022] This invention effectively prevents water from entering the knob switch through gaps by setting a waterproof silicone 3 between the housing 1 and the panel 4, and by fitting the waterproof silicone 3 and the housing side wall 5 between the outer ring wall 8 and the first hook 9 of the outer ring 6 of the knob, and by sealing the outer ring wall 8 with the waterproof silicone 3 and hooking the first hook 9 with the inner side of the housing side wall 5.

[0023] Furthermore, in another embodiment, the waterproof silicone 3 has an annular notch 10 on the inner side of its top, and a sealing rib 11 is provided on the outer side of its top, the sealing rib 11 abutting against the outer ring wall 8.

[0024] By setting an annular notch 10 at the top of the waterproof silicone 3, a sealing structure is formed between the waterproof silicone 3, the side wall of the housing 5, and the knob body 2 when the knob body 2 is not rotated; when the knob is rotated, the waterproof silicone 3 is squeezed and deformed to the annular notch 10, the squeezing rebound force between the waterproof silicone 3 and the knob body 2 is reduced, and the friction is also reduced, while the waterproof silicone 3 and the knob body 2 are still sealed, and the waterproof function is still achieved without affecting the rotation torque of the knob body 2.

[0025] Furthermore, in another embodiment, the inner side of the housing sidewall 5 is provided with an annular edge 12 that engages with and connects to the first hook 9.

[0026] The ring 12 provided on the inner side of the housing side wall 5 is connected with the first hook 9 to enhance the firmness of the connection between the outer ring 6 of the knob and the side wall 5 of the housing.

[0027] Furthermore, in another embodiment, the bottom of the transparent disk 7 is fixedly connected with a plurality of second hooks 13 that are evenly distributed at equal angles.

[0028] Furthermore, in another embodiment, the outer ring 6 of the knob is provided with an inner ring wall 14 for connecting two adjacent first hooks 9, and the inner ring wall 14 is hooked and connected to the second hook 13.

[0029] By fixing multiple second hooks 13 to the bottom of the transparent disc 7 and connecting them to the inner ring wall 14 of the outer ring 6 of the knob, the connection between the transparent disc 7 and the outer ring 6 of the knob is tighter and more stable, and it is less likely to fall off or loosen.

[0030] Furthermore, in another embodiment, an annular groove 15 is provided on the outer periphery of the transparent disk 7, and an O-ring 16 is installed in the annular groove 15.

[0031] By installing an O-ring 16 in the annular groove 15 on the outer periphery of the transparent disc 7, a seal is formed between the transparent disc 7 and the outer ring 6 of the knob, further enhancing the waterproof performance of the knob switch.
