Description

Technical Field

[0001] This application relates to the technical field of thermostats, and in particular to a thermostat. Background Technology

[0002] A thermostat is an automated device used to monitor ambient temperature and maintain a set temperature range by controlling heating and cooling equipment. It is widely used in home appliances, industrial equipment, agriculture, and other fields, and is a core component of temperature control systems.

[0003] The existing thermostat includes a base, a decorative frame attached to the base, and a display panel attached to the decorative frame. The decorative frame is connected to the base by several screws. When users want to change to a different colored decorative frame, they need to loosen each screw with a screwdriver, then replace it with their preferred frame, and finally tighten each screw to secure the frame to the base. Loosening or tightening the screws makes changing the decorative frame cumbersome and inefficient, which needs improvement. Utility Model Content

[0004] The purpose of this application is to provide a thermostat to improve the efficiency of replacing decorative frames.

[0005] The temperature controller provided in this application adopts the following technical solution: The device includes a decorative frame, a base, and a display panel connected to the decorative frame. The decorative frame surrounds the display panel. The base has two sets of elastic portions spaced apart. The inner ring of the decorative frame has first snap-fit ​​portions corresponding to the elastic portions one by one. Each elastic portion has a first snap-fit ​​groove. The first snap-fit ​​portion engages with the first snap-fit ​​groove. The inner wall of the first snap-fit ​​groove has a guide surface for abutting against the first snap-fit ​​portion.

[0006] By adopting the above technical solution, when installing the thermostat, the base is first installed on the wall. The decorative frame is then moved closer to the base, and the display panel moves with it. The first snap-fit ​​part abuts against the elastic part, causing the elastic part to deform under pressure and maintain a tendency to return to its elastic state until the first snap-fit ​​part aligns with the first snap-fit ​​groove. The elastic part then returns to its elastic state, allowing the first snap-fit ​​part to engage with the first snap-fit ​​groove. This engagement improves the stability of the connection between the base and the decorative frame. When the decorative frame needs to be removed, it is moved away from the base. The first snap-fit ​​part abuts against the guide surface, causing the elastic part to deform under pressure, disengaging it from the first snap-fit ​​groove. The decorative frame can then be removed from the base, avoiding the cumbersome operation of traditional screw connections and improving the efficiency of frame replacement. When the decorative frame separates from the base, the elastic part returns to its elastic state, allowing the first snap-fit ​​part to re-engage with the first snap-fit ​​groove.

[0007] Optionally, each of the elastic portions is provided with a guide surface on the side near the decorative frame, the guide surface being located at the end of the elastic portion near the display panel.

[0008] By adopting the above technical solution, during the installation of the decorative frame, the first snap-fit ​​part abuts against the guide surface and applies force to the guide surface. The elastic part is compressed and undergoes elastic deformation, maintaining a tendency to elastically return to its original position until the first snap-fit ​​part aligns with the first snap-fit ​​groove. At this point, the elastic part elastically returns to its original position, and the first snap-fit ​​part snaps into the first snap-fit ​​groove, thereby achieving the connection between the decorative frame and the base. The guide surface guides the installation of the decorative frame, allowing the elastic part to undergo elastic deformation, thus improving the efficiency of the installation between the decorative frame and the base.

[0009] Optionally, the decorative frame is provided with a positioning block, and the base is provided with a first positioning groove, which is used to cooperate with the positioning block.

[0010] By adopting the above technical solution, the cooperation between the positioning block and the positioning groove plays a positioning role in the installation of the decorative frame, so that the decorative frame is accurately installed on the base.

[0011] Optionally, the display panel is provided with a second snap-fit ​​portion, and the decorative frame is provided with a second snap-fit ​​groove corresponding to each group of the second snap-fit ​​portions, wherein the second snap-fit ​​portion engages with the second snap-fit ​​groove.

[0012] By adopting the above technical solution, the second snap-fit ​​part and the second snap-fit ​​slot engage, improving the stability of the connection between the decorative frame and the display panel. Optionally, the base includes an outer shell and an inner shell, the elastic part is disposed on the inner shell, and the outer shell and the inner shell are connected by a locking member.

[0013] By adopting the above technical solution, other parts can be installed between the outer shell and the inner shell. The outer shell and the inner shell are connected by a locking device, which improves the stability of the connection between the outer shell and the inner shell.

[0014] Optionally, the outer shell is provided with a positioning post, and the inner shell is provided with a second positioning groove, the second positioning groove being used to cooperate with the positioning post.

[0015] By adopting the above technical solution, the cooperation between the positioning post and the second positioning groove plays a positioning role in the installation between the outer shell and the inner shell, so that the outer shell is accurately installed on the inner shell, thereby improving the efficiency of the installation of the outer shell and the inner shell through the locking device.

[0016] Optionally, the inner shell is provided with a plurality of third snap-fit ​​parts, and the outer shell is provided with third snap-fit ​​grooves corresponding to the third snap-fit ​​parts one by one, and the third snap-fit ​​parts engage with the third snap-fit ​​grooves.

[0017] By adopting the above technical solution, the snap-fit ​​between the third snap-fit ​​part and the third snap-fit ​​groove further improves the stability of the installation between the inner shell and the outer shell.

[0018] Optionally, the decorative frame is provided with a positioning ring block, the second snap-fit ​​groove and the first snap-fit ​​part are both provided on the positioning ring block, and the outer shell is provided with a positioning cavity for cooperating with the positioning ring block.

[0019] By adopting the above technical solution, the cooperation between the positioning ring block and the positioning cavity plays a positioning role in the installation between the decorative frame and the outer shell, so that the decorative frame is accurately installed on the outer shell. The cooperation between the first snap-fit ​​part and the first snap-fit ​​groove of the decorative frame and the inner shell improves the installation efficiency.

[0020] Optionally, the housing is provided with a number of heat dissipation holes.

[0021] By adopting the above technical solution, the heat dissipation holes can realize the heat dissipation function of the thermostat, and avoid the accumulation of internal heat affecting the performance of the thermostat.

[0022] Optionally, it also includes a light-transmitting plate, which is connected to the side of the display panel away from the base, and the side of the light-transmitting plate away from the display panel is flush with one side of the decorative frame.

[0023] By adopting the above technical solution, the light-transmitting plate can protect the display panel, and at the same time, the side of the light-transmitting plate away from the display panel is flush with the side of the decorative frame, making the thermostat look flatter and more beautiful.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. When it is necessary to remove the decorative frame, move the decorative frame away from the base. The first snap-fit ​​part abuts against the guide surface and causes the elastic part to be compressed and deformed elastically, so that the first snap-fit ​​part disengages from the first snap-fit ​​groove. The decorative frame can then be removed from the base, avoiding the cumbersome operation of the traditional screw connection method and improving the replacement efficiency of the decorative frame.

[0025] 2. The cooperation between the positioning block and the positioning groove plays a positioning role in the installation of the decorative frame, so that the decorative frame is accurately installed on the base. Attached Figure Description

[0043] The implementation principle of a temperature controller according to an embodiment of this application is as follows: When installing the thermostat, first mount the base 2 on the wall. Move the decorative frame 1 closer to the base 2. The display panel 3 moves with the decorative frame 1, and the first snap-fit ​​part 12 abuts against the elastic part 223. This causes the elastic part 223 to be compressed and undergo elastic deformation, maintaining a tendency to elastically return to its original position until the first snap-fit ​​part 12 aligns with the first snap-fit ​​groove 2231. The elastic part 223 then elastically returns to its original position, allowing the first snap-fit ​​part 12 to snap into the first snap-fit ​​groove 2231. This snap-fit ​​engagement improves the stability of the connection between the base 2 and the decorative frame 1. When it is necessary to remove the decorative frame 1, move it away from the base 2. The first snap-fit ​​part 12 abuts against the guide surface, causing the elastic part 223 to be compressed and undergo elastic deformation, disengaging the first snap-fit ​​part 12 from the first snap-fit ​​groove 2231. The decorative frame 1 can then be removed from the base 2, avoiding the cumbersome operation of traditional screw connections and improving the efficiency of replacing the decorative frame 1.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
