[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-6 The present invention provides an embodiment of a thermostat waterproof housing, comprising a thermostat rear housing 1 and a front decorative housing 2 for buckling with the thermostat rear housing 1. A columnar connection structure for maintaining the connection is installed at the corner position of the opposite surfaces of the thermostat rear housing 1 and the front decorative housing 2. A boss 3 is integrally formed on the outer wall of the thermostat rear housing 1 on the side close to the front decorative housing 2, and at least two sealing rings 4 are provided on the outer edge of the boss 3. A groove 7 for the sealing ring 4 to enter is provided on the inner wall of the front decorative housing 2.

[0021] The outer edge of the rear housing 1 of the thermostat is integrally formed with an outer edge 6, and the thickness of the outer edge 6 is 0.5 cm to 1 cm;

[0022] The column type connecting structure comprises a hollow reference column 301 fixed at the corner position of the boss 3 and a guide pin 201 fixed on the inner wall of one side of the front decorative shell 2, and the guide pin 201 and the hollow reference column 301 are in a concentric interference fit, when the temperature controller rear shell 1 and the front decorative shell 2 are docked, the hollow reference column 301 and the guide pin 201 are docked, the interference fit of the two can provide accurate positioning, and the tightness of the interference fit can effectively resist shear force and tension, and the components can maintain stable positions after assembly, reducing displacement caused by vibration or external force, thereby improving the accuracy of the entire assembly.

[0023] The corner position of the inner wall of one side of the front decorative shell 2 is provided with an elastic back-embedding structure 8, and the surface of the boss 3 is provided with a herringbone seat 5 that forces the elastic back-embedding structure 8 to deform, when the temperature controller rear shell 1 and the front decorative shell 2 are assembled and fastened, the herringbone seat 5 will force the elastic back-embedding structure 8 to act, thereby feeding back the assembly degree of the temperature controller rear shell 1 and the front decorative shell 2; the elastic back-embedding structure 8 comprises a base plate 801 fixed on the inner wall of one side of the front decorative shell 2, a rotating shaft 802 rotatably installed inside the base plate 801, a round handle 804 fixed at one end of the rotating shaft 802, and a force storage torsional spring 806 sleeved on the outer circumferential surface of the rotating shaft 802, a first columnar support head 803 is fixed on the outer wall of the side of the base plate 801 close to the round handle 804, a second columnar support head 805 is fixed on the outer wall of the side of the round handle 804 close to the base plate 801, one end of the force storage torsional spring 806 extends to the inside of the first columnar support head 803, and the other end of the force storage torsional spring 806 is in contact with the lower surface of the second columnar support head 805.

[0024] When the staff tightens the temperature controller rear shell 1 and the front decorative shell 2, the herringbone seat 5 contacts the upper arc surface of the round handle 804, so that the round handle 804 is forced to swing downward around the rotating shaft 802, thereby causing the force storage torsional spring 806 to be pulled and deformed, as the tightening degree of the temperature controller rear shell 1 and the front decorative shell 2 increases, the deformation amount of the force storage torsional spring 806 also gradually increases, to real-time feedback the assembly degree of the temperature controller rear shell 1 and the front decorative shell 2, and the herringbone seat 5 and the elastic back-embedding structure 8 located between the temperature controller rear shell 1 and the front decorative shell 2 can provide a tight combination, which can resist external impact and vibration and reduce failures caused by loose structure.

[0025] When using the embodiment of the present application, first ensure that all parts have been cleaned, especially the sealing ring 4 and the embedded groove 7, to prevent dust and debris from affecting the sealing effect. At the same time, check the integrity of the embedded groove 7 to ensure that there are no cracks or damage. Align the thermostat rear shell 1 with the front decorative shell 2, that is, the outer edge of the boss 3 of the thermostat rear shell 1 is aligned with the inner wall surface of the front decorative shell 2, and then tighten the thermostat rear shell 1 and the front decorative shell 2. At this time, the thermostat rear shell 1 and the front decorative shell 2 are fixed together through the column connection structure. The interference fit of the column connection structure in this process can ensure a tight connection between the two, reduce the generation of gaps, and the sealing ring The elastic properties of 4 enable it to maintain a good shape during the subsequent connection process. During the connection process, uniform pressure is gradually applied to ensure that the sealing ring 4 is compressed into place and enters the interior of the embedding groove 7. After the connection is completed, the sealing ring 4 forms good contact with the embedding groove 7 of the front decorative shell 2, forming an effective sealed water-blocking area. When external moisture contacts the thermostat, the elastic material of the sealing ring 4 can effectively resist the penetration of moisture and form a waterproof barrier. Even in high humidity or accidental splashing, the structural design of the sealing ring 4 and the embedding groove 7 can ensure the safety of the interior of the thermostat and avoid short circuit or corrosion caused by moisture intrusion.
