Description

Technical Field

[0001] The utility model relates to the field of smart home control panels, in particular to a temperature control panel. Background Art

[0002] Smart home control panels are widely used in the smart home field. In a smart home system, a smart home control panel is usually directly or indirectly electrically connected to smart home products, and the smart home products are controlled through the smart home control panel. For example, air conditioners, lamps, televisions, smart curtains, etc. are necessary supporting facilities for smart homes. Among them, when it comes to situations that require multi-gear adjustment such as adjusting temperature, wind force, humidity, etc., a rotary control panel in the smart home control panel is usually used, and such a rotary control panel is vertically installed on the wall.

[0003] The prior art (authorized publication number: CN214474696U) discloses a rotary control panel, and its specification specifically discloses that "the rotary control panel further includes a light-transmitting member, and at least part of the light-transmitting member is disposed in the gap formed between the hole wall of the first hole and the outer periphery of the knob". Combining with the accompanying drawings in its specification Figure 5 it can be seen that although the 55th paragraph of its specification claims that the light-transmitting member can play a role in dust prevention and waterproofing, however, due to the gap between the light-transmitting member and the outer periphery of the knob, when external liquid is directly splashed on the rotary control panel, the liquid will reach the internal control main board through the gap between the light-transmitting member and the knob. And the control main board is mostly a circuit board, and once it is soaked in water, it is easy to short-circuit and even be corroded, and the waterproof effect that the light-transmitting member can achieve is poor. Summary of the Utility Model

[0004] The purpose of the embodiment of the present application is to provide a temperature control panel to solve the problem that although a light-transmitting member is arranged on the outer periphery of the existing rotary control panel, the waterproof effect that the light-transmitting member can achieve is limited. The specific technical solution is as follows:

[0005] In the first aspect of the embodiment of the present application, a temperature control panel is applied to a smart home system and controls smart home products in the smart home system. It includes a base and a knob. The knob is rotatably connected to the base. The base is provided with an opening to accommodate the knob. A sealing ring is arranged between the opening and the knob. The sealing ring is provided with a first clamping groove, and the knob is provided with a first clamping protrusion. The first clamping groove is arranged in the first clamping protrusion and forms a tortuous channel between the knob and the sealing ring.

[0006] In some embodiments, the knob includes a knob body and an extension portion coaxially connected thereto. A step is formed at the connection between the knob body and the extension portion. The first convex is provided on the extension portion, and the first convex and the knob body respectively serve as two sides constituting the diversion groove.

[0007] In some embodiments, a diversion opening is provided on the sealing ring. The diversion opening is communicated with the first clamping groove and is arranged below the knob.

[0008] In some embodiments, an avoidance groove is provided in the opening for installing the sealing ring. A second convex is provided in the avoidance groove, and a second clamping groove is provided on the sealing ring. The second clamping groove abuts against the second convex.

[0009] In some embodiments, a protrusion is provided on the first convex. A limiting post spanning the first clamping groove is arranged in the first clamping groove. The limiting post is used to block the protrusion, and a water flow channel is provided between the limiting post and the bottom surface of the first clamping groove.

[0010] Advantages of the embodiments of the present application:

[0011] 1. The tortuous channel formed by designing the first convex on the knob and cooperating with the first clamping groove of the sealing ring in the present application can block external liquid from entering the temperature control panel.

[0012] 2. The first convex cooperates with the knob body to form a diversion groove, which can store liquid and guide the liquid to flow out from below the knob.

[0013] 3. A diversion opening is formed on the sealing ring to guide the liquid in the first clamping groove to flow out.

[0014] 4. Designing a protrusion on the first convex and cooperating with the limiting post in the first clamping groove can prevent the knob from being twisted excessively.

[0015] Additional aspects and advantages of the present utility model will be given in part in the following description, become apparent in part from the following description, or be understood through the practice of the present utility model.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts shall fall within the protection scope of the present utility model.

[0025] This article describes a temperature control panel, which is mainly applied to a smart home system. Specifically, the temperature control panel directly or indirectly controls smart home products in the smart home system. Since the temperature control panel can perform multi-gear adjustment, it is suitable for adjusting temperature, brightness, humidity, wind force, etc.

[0026] Please refer to Figures 1-4,In the embodiment of the present utility model, a temperature control panel is provided to solve the problem of poor waterproof ability of the existing rotary control panel. It should be noted that this application is designed for a vertically installed rotary control panel. Specifically, the temperature control panel includes a base 1 and a knob 2. The knob 2 is rotatably connected to the base 1. The base 1 is provided with an opening to accommodate the knob 2. The opening is provided with an avoidance groove 11. A sealing ring 3 is provided in the avoidance groove 11. The knob 2 passes through the sealing ring 3 and is in clearance fit with it. The knob 2 is provided with a first convex 23, and the sealing ring 3 is provided with a first groove 31. The first convex 23 is arranged in the first groove 31. It is worth mentioning that the first groove 31 and the first convex 23 are also in clearance fit, that is, there is also a gap between the first groove 31 and the first convex 23, so as to form a tortuous channel between the knob 2 and the sealing ring 3. When external liquid splashes into the opening of the base 1, the liquid will first be blocked by the first convex 23 and cannot directly enter the interior of the base 1, so that the temperature control panel has better waterproof ability;

[0027] Please refer to Figure 3 , Figure 5 and Figure 6 , in a preferred embodiment, the knob 2 is a stepped knob. The knob 2 includes a knob body 21 and an extension part 22 coaxially connected thereto. Since the cross-sectional area of the extension part 22 is smaller than that of the knob body 21, a step is formed at the connection between the two;

[0028] The first convex 23 is arranged on the extension part 22. The first convex 23 and the knob body 21 respectively serve as two sides of the diversion groove. Specifically, the side surface of the first convex 23 and the side surface of the knob body 21 respectively serve as two sides of the diversion groove, and the surface of the extension part 22 serves as the bottom surface of the diversion groove. In this way, after the above-mentioned liquid is blocked by the first protrusion, most of the liquid will flow into the diversion groove. The liquid flowing into the diversion groove will be affected by gravity and guided by the diversion groove to gather at the bottom of the diversion groove and drip into the opening, and finally drain out along the opening. By designing the diversion groove, the liquid is further guided to flow out on the basis of waterproofing; and a small part of the liquid will enter the first groove 31 of the sealing ring 3. Therefore, a diversion port 32 needs to be designed on the sealing ring 3. The diversion port 32 is communicated with the first groove 31 and the diversion port 32 is arranged below the knob 2. This part of the liquid flows along the first groove 31 to the diversion port 32, and flows into the opening and drains out. Although the above-mentioned embodiment is designed for a vertically installed rotary control panel, compared with the prior art structure of a simple light-transmitting member, even if this embodiment is installed horizontally, the waterproof effect is still better than that of the prior art.

[0029] Please refer to Figure 3, To firmly place the sealing ring 3 in the avoidance groove 11, the friction between the sealing ring 3 and the avoidance groove 11 can be increased. Exemplarily, a second clamping protrusion 12 is provided in the avoidance groove 11, and a second clamping groove 33 is provided on the sealing ring 3. The second clamping groove 33 abuts against the second clamping protrusion 12. Exemplarily, the bottom surface of the avoidance groove 11 or the outer surface of the sealing ring 3 is an uneven rough surface.

[0030] Generally, the rotation angle of the knob 2 on the base 1 is limited. To protect the knob 2 from being over-rotated and thus damaging the firmware, the present application provides an embodiment. Specifically, a protrusion 24 is provided on the first clamping protrusion 23, and a limiting column 34 spanning the first clamping groove 31 is provided in the first clamping groove 31. The limiting column 34 is used to block the protrusion 24. When the knob 2 is rotated to a predetermined angle, the protrusion 24 will be blocked by the limiting column 34 to prevent the knob 2 from being over-rotated. The limiting column 34 and the sealing ring 3 are integrally formed and the material is silica gel. Therefore, the limiting column 34 can also play a buffering role. In order not to affect the first clamping groove 31 to guide the liquid flow, exemplarily, the limiting column 34 is arranged away from the bottom surface of the first clamping groove 31. Exemplarily, a water flow channel is provided between the limiting column 34 and the bottom surface of the first clamping groove 31. In this way, after the liquid enters the first clamping groove 31, it can flow along the bottom surface of the first clamping groove 31 and pass under the limiting column 34.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
