[0037] As Figure 1-9 shown, the present application provides a waterproof knob assembly 10, which includes a housing 100, a knob member 200, a knob bracket 300, and a first waterproof ring 400.

[0038] As Figure 2 , Figure 8 and Figure 9 shown, the housing 100 includes a receiving cavity 110. Specifically, the housing 100 is formed with a receiving cavity. The housing 100 includes a housing cover plate 120, and the housing cover plate 120 includes a first knob through hole 121 communicating with the receiving cavity 110. The housing 100 further includes a support surrounding plate 130 disposed on the side of the housing cover plate 120 away from the receiving cavity 110, and the support surrounding plate 130 is disposed around the first knob through hole 121. Optionally, the support surrounding plate 130 forms a second knob through hole 131 communicating with the first knob through hole 121.

[0039] Optionally, the support surrounding plate 130 is disposed around the first knob through hole 121, specifically, it can be disposed around the central axis of the first knob through hole 121.

[0040] In an alternative embodiment, the second knob through hole 131 and the first knob through hole 121 can be coaxially disposed.

[0041] As Figure 1 、 Figure 3 and Figure 6 shown, the knob member 200 is rotatably disposed on the housing 100, including a main body portion 210 rotatably disposed with the support surrounding plate 130, a handle portion 220 disposed on the main body portion 210 and disposed around the support surrounding plate 130, and a first connecting portion 230 disposed on the main body portion 210 and at least partially located in the second knob through hole 131.

[0042] Optionally, by providing the blocking portion 320 and the housing cover plate 120, the knob bracket 300 can be prevented from exiting through the first knob through hole 121, so that the knob bracket 300 is at least partially stably located in the receiving cavity 110.

[0043] As Figure 3 shown, the first waterproof ring 400 is disposed between the main body portion 210 and the support surrounding plate 130.

[0044] In the above embodiments, by providing the second knob through hole 131 and the first knob through hole 121, and connecting the knob member 200 and the knob bracket 300 through the first connecting portion 230 at least partially located in the second knob through hole 131 and the second connecting portion 310 at least partially located in the first knob through hole 121, and by rotatably disposing the knob member 200 on the housing 100 and providing the first waterproof ring 400 between the main body portion 210 of the knob member 200 and the support surrounding plate 130 of the housing 100, it is possible to effectively reduce or avoid liquid from entering the second knob through hole 131, the first knob through hole 121, and the receiving cavity 110 through the gap between the main body portion 210 and the first waterproof ring 400, ensuring the waterproofness of the entire waterproof knob assembly 10, thereby effectively reducing or avoiding damage to the circuit board in the receiving cavity 110. And by providing the support surrounding plate 130 protruding from the housing cover plate 120, it is also possible to provide a certain blocking effect on the liquid sputtered or dropped onto the housing cover plate 120, preventing the liquid from entering the second knob through hole 131, the first knob through hole 121, and the receiving cavity 110, so that the entire waterproof knob assembly 10 has good waterproofness.

[0045] In an alternative embodiment, the waterproof knob assembly 10 provided in the present application can be applied to some outdoor sensor devices or outdoor controller devices, such as outdoor controllers such as outdoor timing water valves, or outdoor sensors such as soil detectors.

[0046] As Figure 3 - Figure 5As shown, the first waterproof ring 400 includes a base portion 410, a first water-stop portion 420 and a second water-stop portion 430 respectively disposed at two ends of the base portion 410. The first water-stop portion 410, the second water-stop portion 420 and the base portion 430 form a first water-stop groove 440 and a second water-stop groove 450. That is, the first water-stop portion 420 and the second water-stop portion 430 are disposed at the ends of the base portion 410 and extend toward both sides of the base portion 410, so that the first water-stop groove 440 and the second water-stop groove 450 are respectively formed on both sides of the base portion 410.

[0047] Optionally, the opening directions of the first water-stop groove 440 and the second water-stop groove 450 are opposite, but both are located on the side away from the base portion 410.

[0048] As Figure 3 shown, the first waterproof ring 400 is sleeved on the support shroud 130 through the first water-stop groove 440.

[0049] As Figure 3 shown, the main body portion 210 further includes a support portion 211, and the support portion 211 is nested in the second water-stop groove 450 and is disposed opposite to the support shroud 130.

[0050] Optionally, by setting the first waterproof ring 400 in a double-groove shape and sleeving it on the support shroud 130 and the support portion 211 respectively, on the one hand, the support stability of the support shroud 130 and the support portion 211 can be better improved, so that the knob member 200 can be stably rotated and supported on the housing 100. On the other hand, a plurality of water-blocking structures are formed between the first water-stop groove 440 and the support shroud 130, the second water-stop groove 450 and the support portion 211 (such as between the support shroud 130 and the first water-stop portion 410, between the support shroud 130 and the base portion 410, etc.), which can effectively prevent liquid from entering the second knob through-hole 131, the first knob through-hole 121 and the accommodation cavity 110.

[0051] Optionally, the support portion 211 and the handle portion 220 are spaced apart, thereby forming a rotatable space between the knob member 200 and the housing 100.

[0052] In an alternative embodiment, the first waterproof ring 400 is a flexible structure.

[0053] In an alternative embodiment, its first water-stop portion 420 is farther from the first connection portion 230 than the second water-stop portion 430. That is, relatively speaking, the first water-stop portion 420 is located outside the second water-stop portion 430, and the axial length of its first water-stop portion 420 is greater than that of the second water-stop portion 430. That is, the extension length of the first water-stop portion 420 extending toward at least one side of the base portion 410 is greater than the extension length of the second water-stop portion 430.

[0054] In an alternative embodiment, the first water stop portion 420 extends on both sides of the base portion 410 by a length greater than the extension length of the second water stop portion 430.

[0055] Optionally, since the first water stop portion 420 is disposed outside relative to the second water stop portion 430 and is more likely to come into contact with liquid, by setting the length of the first water stop portion 420 to be larger, the contact area between it and the support shroud 130 and / or the support portion 211 can be increased, thereby improving the water blocking effect of the water blocking structure formed by the first water stop portion 420 and the support shroud 130 and / or the support portion 211. And at the same time, the cooperation stability between the first waterproof ring 400 and the support shroud 130 and / or the support portion 211 is also improved.

[0056] As Figure 3 shown, the waterproof knob assembly 10 further includes a second waterproof ring 500 sleeved on the second connecting portion 310 and disposed between the blocking portion 320 and the housing cover plate 120.

[0057] In an alternative embodiment, by further providing a second waterproof ring 500 between the blocking portion 320 and the housing cover plate 120, a waterproof structure can be further formed to prevent the liquid or water vapor entering the second knob through hole 131 and the first knob through hole 121 from further entering the accommodation cavity 110, so as to improve the overall waterproof effect.

[0059] Optionally, by providing the stepped portion 321 on the blocking portion 320, providing a stepped groove 121 corresponding to the stepped portion 321 on the housing cover plate 120, and disposing the second waterproof ring 500 between the stepped portion 321 and the stepped groove 121, on the one hand, the second waterproof ring 500 can be better positioned between the blocking portion 320 and the housing cover plate 120 to reduce its shaking or displacement, and on the other hand, the contact between the blocking portion 320 and the second waterproof ring 500, and between the housing cover plate 120 and the second waterproof ring 500 can be effectively achieved in multiple directions, effectively improving the waterproof effect.

[0060] As Figure 3 、 Figure 6 and Figure 7As shown, the first connecting portion 230 includes a fixing blind hole 231, the second connecting portion 310 is provided with a fixing through hole 311, and the waterproof knob assembly 10 further includes a fixing member 600. The fixing member 600 sequentially penetrates through the fixing through hole 311 and the fixing blind hole 231 from the direction of the second connecting portion 310 away from the first connecting portion 230 to connect the second connecting portion 310 with the first connecting portion 230.

[0061] That is, the fixing member 600 passes through the fixing through hole 311 and is embedded in the fixing blind hole 231, thereby connecting the second connecting portion 310 with the first connecting portion 230.

[0062] In an alternative embodiment, the fixing member 600 is a screw.

[0063] Optionally, by sequentially penetrating the fixing through hole 311 and the fixing blind hole 231 from the direction of the second connecting portion 310 away from the first connecting portion 230 with the fixing member 600 to connect the second connecting portion 310 with the first connecting portion 230, it is possible to avoid punching through holes in the first connecting portion 230, effectively reduce the generation of gaps, improve the waterproof performance, and by providing the fixing member 600, the knob bracket 300 and the knob member 200 can be fixed and clamped on the housing 100, so that the knob member 200 and the housing 100 can better abut against the first waterproof ring 400, and the knob bracket 300 and the housing 100 can better abut against the second waterproof ring 500, thereby ensuring the waterproof effect of the first waterproof ring 400 and the second waterproof ring 500.

[0064] In an alternative embodiment, the first connecting portion 230 and the second connecting portion 310 are nested with each other. Optionally, the first connecting portion 230 is provided with a groove, and the second connecting portion 310 is embedded in the first connecting portion 230. It is also possible that the second connecting portion 310 is provided with a groove, and the first connecting portion 230 is embedded in the groove. This is not limited here, thereby effectively improving the connection stability between the first connecting portion 230 and the second connecting portion 310.

[0065] Such as Figure 6 and Figure 7 As shown, the knob member 200 includes a torsional radial rib 250 disposed between the main body portion 210 and the first connecting portion 230, and the second connecting portion 310 is provided with a torsional groove 312 corresponding to the torsional radial rib 250.

[0066] Wherein, the torsional radial rib 250 cooperates with the torsional groove 312 so that the first connecting portion 230 can drive the second connecting portion 230 to twist.

[0067] Optionally, by providing radial torsion ribs 250 on the knob member 200 to cooperate with the torsion groove 312 of the second connecting portion 310, circumferential limitation between the knob member 200 and the knob bracket 300 is achieved, so that when the knob member 200 rotates, it can drive the knob bracket 300 to rotate.

[0068] In an alternative embodiment, it may also be that the fixing member 600, the fixing through hole 31, and the fixing blind hole 231 cooperate with each other so that the first connecting portion 230 can drive the second connecting portion 230 to twist, which is not limited here.

[0069] In an alternative embodiment, it may also be that the fixing member 600, the fixing through hole 31, and the fixing blind hole 231 cooperate with each other and the torsion radial ribs 250 of the knob member 200 cooperate with the torsion groove 312 of the second connecting portion 310 so that the first connecting portion 230 can drive the second connecting portion 230 to twist, which is not limited here.
