[0029] Thermostat products will have a disassembly hole at the connection between the panel housing and the power box. In some application scenarios that require a waterproof level, water vapor may enter the interior of the thermostat through the disassembly hole, thereby adversely affecting the electrical components inside the thermostat. The inventor noted that by adjusting the structure of the hard connection between the thermostat panel housing and the power box part, and installing the sealing device in the present application, the disassembly hole of the thermostat can be isolated from the internal space of the thermostat. Therefore, the disassembly hole equipped with a sealing device not only facilitates the insertion of the disassembly tool into the panel housing, but also plays a role in sealing against water and dust. In addition, since the disassembly hole of the thermostat is isolated from the internal space of the thermostat, the sealing structure can also prevent the disassembly tool from being accidentally inserted into the interior of the thermostat during the disassembly process, thereby damaging the internal electrical components.

[0030] Figure 1A and Figure 1B The overall structure of the thermostat is shown; Figure 1AA three-dimensional diagram of the thermostat of the present application; Figure 1B for Figure 1A A three-dimensional view of the central thermostat behind the hidden controller panel.

[0031] like Figure 1A-1B As shown, the thermostat housing sealing structure 100 is a sealing structure having a housing and internal components, including a thermostat panel 102, a first housing 104 (e.g., a panel housing), a second housing 106 (e.g., a power box housing), and electrical components (not shown in the figure) disposed inside the first housing and the second housing. The thermostat panel 102 is mounted on one side of the first housing 104, and the second housing 106 and the first housing 104 are detachably mounted on the other side of the first housing 104 relative to the thermostat panel 102 through a snap-fit ​​structure.

[0032] Figure 2A and Figure 2B is an exploded view of the thermostat, thereby showing more details of the thermostat; Figure 2A An exploded view of the thermostat of the present application from the front side perspective; Figure 2B This is an exploded view of the thermostat of the present application from a rear side perspective.

[0033] like Figure 2A-2BAs shown, a disassembly hole 252, 254 is provided at the connection between the first shell 104 and the second shell 106. According to different structural design requirements, the disassembly hole can be set on the first shell 104 or the second shell 106, and the number of disassembly holes can also be adjusted according to structural requirements. In the embodiment of the present application, the disassembly holes 252, 254 are symmetrically arranged on the lower edge of the first shell 104, and the number is two. The disassembly holes 252, 254 have a semi-open structure, and the direction of the opening is toward the second shell 106. The thermostat shell sealing structure 100 includes a sealing device 202, 204, such as a rubber plug, and the number of the sealing device is determined according to the number of disassembly holes. In the embodiment of the present application, two rubber plugs 202, 204 are provided, and each rubber plug is arranged near a corresponding disassembly hole. A first shell protrusion 242, 244 is provided on the inner side of the first shell 104, and a second shell protrusion 222, 224 is provided on the inner side of the second shell 106, and each first shell protrusion or second shell protrusion corresponds to a disassembly hole. The first shell protrusion 242, 244 and the second shell protrusion 222, 224 are in a U-shape, and the opening direction of the U-shape is toward the corresponding disassembly hole. The rubber plug 202, 204 is arranged between the first shell protrusion 242, 244 and the second shell protrusion 222, 224 to isolate the internal space of the thermostat shell sealing structure 100 from the outside of the disassembly hole 252, 254, thereby playing a sealing role. The thermostat shell sealing structure 100 also has a snap-on structure, specifically, a first shell snap-on structure 232, 234 is provided on the inner side of the first shell 104, and a second shell snap-on structure 212, 214 is also provided on the inner side of the second shell 106, and the first shell snap-on structure 232, 234 and the second shell snap-on structure 212, 214 are arranged below the thermostat shell sealing structure 100. When assembling the first shell 104 and the second shell 106, the first shell snap-in structures 232, 234 and the second shell snap-in structures 212, 214 are detachably engaged together, and the first shell snap-in structures 232, 234 and the second shell snap-in structures 212, 214 can be disengaged by applying external force, so that the first shell 104 and the second shell 106 can be disassembled and separated.

[0034] Figures 3A-3C Other perspectives and cross-sectional views of the thermostat are shown, wherein: Figure 3A for Figure 1A Rear view of the central thermostat; Figure 3B for Figure 3A AA section view of the middle temperature controller; Figure 3C for Figure 3A BB cross-sectional view of the medium temperature controller.

[0035] like Figure 3A-3BAs shown, when the first shell 104 and the second shell 106 are connected, they have the above-mentioned snap structures 214 and 234 to keep them relatively fixedly connected. The snap structures 212 and 232 are the same as the snap structures 214 and 234, so they are not described again. Figure 3C Another set of snap structures 302, 304 disposed on the upper part of the thermostat housing sealing structure 100 is shown, and its working principle is similar to that of the snap structures 214, 234, and will not be repeated here. The snap structures 214, 234 include the first housing snap structure 234 and the second housing snap structure 214. During assembly, the first housing snap structure 234 and the second housing snap structure 214 are hooked together through the hooks 312, 314 in front of them, respectively, so that the first housing 104 and the second housing 106 are fixed together.

[0036] Figure 3C The connection relationship of one of the two rubber stoppers 202 and 204 is shown. Figure 3C As shown, during assembly, the first housing protrusion 244 of the first housing 104 and the second housing protrusion 224 of the second housing 106 are spaced a certain distance apart from each other. The first housing protrusion 244 and the second housing protrusion 224 are respectively embedded in the first housing side surface groove 412 and the second housing side surface groove 414 of the rubber plug 204 (see Figures 4A-4C ), since the rubber plug 204 is elastic, the first shell protrusion 244 and the second shell protrusion 224 can form an interference fit connection with the rubber plug 204, so that the rubber plug 204 forms a relatively sealed connection between the first shell 104 and the second shell 106. During assembly, the disassembly hole 254 is set below the rubber plug 204, so that the rubber plug 204 can isolate the internal space of the first shell 104 and the second shell 106 from the space outside the disassembly hole 254, thereby preventing external dust and water vapor from entering the thermostat shell sealing structure 100 to damage the electronic components inside the thermostat shell sealing structure 100.

[0037] The structure and matching relationship of the other rubber plug 202 are the same as those of the rubber plug 204, and will not be described in detail here. In some other embodiments, only a pair of first shell protrusions and second shell protrusions may be provided on the first shell 104 and the second shell 106, and accordingly, only one rubber plug is needed to complete the sealing connection between the first shell 104 and the second shell 106.

[0038] Continue as Figure 3CAs shown, when the first shell 104 and the second shell 106 are disassembled, a disassembly tool 255 (such as a flat-blade screwdriver) can be inserted into the thermostat shell sealing structure 100 from the disassembly hole 254, and then a force F is applied to the disassembly tool 255. Under the action of the lever principle, the hooks 312, 314 of the first shell snap structure 234 and the second shell snap structure 214 can be disengaged from each other, and the other set of snap structures can also be disengaged in a similar manner, so that the first shell 104 and the second shell 106 can be separated from each other. Since a rubber plug 204 is provided above the disassembly hole 254 of the thermostat shell sealing structure 100, when the disassembly tool 255 is inserted into the disassembly hole 254, it will be blocked by the concave cavity top wall 462 (see Figure 4C ) is blocked, so the disassembly tool 255 cannot extend into the internal space of the thermostat housing sealing structure 100, which can prevent the disassembly tool 255 from being accidentally inserted into the thermostat housing sealing structure 100 during the disassembly process, thereby damaging the internal electrical components.

[0039] Figures 4A-4E The specific structure of the sealing device (rubber plugs 202, 204) is shown, wherein Figure 4A A three-dimensional diagram of the sealing device of the present application from a front side perspective; Figure 4B A three-dimensional diagram of the sealing device of the present application from a rear side perspective; Figure 4C A three-dimensional diagram of the sealing device of the present application from a bottom perspective; Figure 4D A front view of the sealing device of the present application; Figure 4E for Figure 4D CC cross-sectional view of the middle sealing device.

[0040] like Figures 4A-4EAs shown, in the embodiment of the present application, the sealing device is a rubber plug 202, 204, which has a first shell side surface 402, a second shell side surface 404, an upper surface 406, a lower surface 408, a front surface 422 and a rear surface 424. The first shell 104 is arranged on one side of the first shell side surface 402, and the second shell 106 is arranged on one side of the second shell side surface 404. A U-shaped first shell side surface groove 412 is arranged on the first shell side surface 402, and the first shell side surface groove 412 is formed by being recessed inward from the first shell side surface 402; the second shell side surface 404 is arranged opposite to the first shell side surface 402, and a U-shaped second shell side surface groove 414 is arranged on the second shell side surface 404, and the first shell side surface groove 412 and the second shell side surface groove 414 have the same shape, and their U-shaped groove openings face the direction of the lower surface 408. The U-shape of the first shell side surface groove 412 is the same as the U-shape of the first shell protrusions 242, 244, and the second shell side surface groove 414 is the same as the U-shape of the second shell protrusions 222, 224, so that the first shell protrusions 242, 244 can be inserted into the first shell side surface groove 412, and the second shell protrusions 222, 224 can be inserted into the second shell side surface groove 414, and an interference fit connection is formed through the elastic deformation of the rubber plugs 202, 204, so that the rubber plug 204 forms a relatively sealed connection between the first shell 104 and the second shell 106.

[0041] Continue as Figures 4A-4E As shown, the upper surface 406 is arranged opposite to the lower surface 408, and the upper surface 406 and the lower surface 408 are adjacent to the first shell side surface 402 and the second shell side surface 404; the front surface 422 is arranged opposite to the rear surface 424, and the front surface 422 and the rear surface 424 are adjacent to the first shell side surface 402 and the second shell side surface 404. A lower surface recess 416 is provided at a position of the lower surface 408 close to the second shell side surface 404, and the lower surface recess 416 is recessed toward the upper surface 406 to form a recessed cavity 418 in the sealing device 202, 204, and the recessed cavity 418 has a recessed cavity guide wall 432, a recessed cavity top wall 462 and two recessed cavity side walls 442 opposite to each other. The recessed cavity guide wall 432 extends from the lower surface 408 to the recessed cavity top wall 462, and its extending direction is arranged at a certain angle to the second shell side surface 404. The two recessed cavity side walls 442 are trapezoidal in shape, vertically extending from the lower surface 408 to the recessed cavity top wall 462 , and adjacent to the recessed cavity guide wall 432 .

[0042] Continue to refer Figures 4A-4E, a second shell side surface opening 452 is provided on the second shell side surface 404 near the recessed cavity 418, the second shell side surface opening 452 faces the second shell 106, and the second shell side surface opening 452 is connected to the lower surface recess 416, thereby forming a larger opening. The disassembly holes 252, 254 are provided on one side of the lower surface 408 of the rubber stopper 202, 204, and correspond to the position of the lower surface recess 416, so that the recessed cavity 418 and the disassembly holes 252, 254 are spatially connected to each other. The U-shaped second shell side surface groove 414 is provided around the second shell side surface opening 452, so that the recessed cavity 418 is isolated from the first shell side surface groove 412, the second shell side surface groove 414 and the upper surface 406. When the disassembly tool 255 is inserted into the disassembly hole 254, it will continue to extend into the recessed cavity 418 and can be inserted into the recessed cavity top wall 462 of the rubber stopper 204 (see Figure 4C ) to prevent the removal tool 255 from extending beyond the rubber plugs 202, 204 and further extending into the housing of the thermostat (see Figure 3C ), thereby protecting the internal electronic components from damage.

[0043] The thermostat of the present application can at least achieve the following beneficial technical effects:

[0044] A rubber plug as described in this article is provided between the panel housing of the thermostat and the power box housing, which can isolate the internal electronic components of the thermostat from the outside of the disassembly hole, thereby preventing water vapor from entering the interior of the thermostat and preventing the disassembly tools from accidentally touching the internal electronic components and causing damage during the disassembly process.
