Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.​​

[0029] In this embodiment of the utility model,

[0030] A wall-mounted thermostat, such as Figures 1-6 As shown, the device includes an integrated regulator 1 and a temperature sensing bulb 2. A connecting tube 3, which communicates with the interior of the temperature sensing bulb 2, passes through the lower side of the temperature sensing bulb 2. The other end of the connecting tube 3 is connected to a controller 4. The controller 4 includes a control tube 5, which communicates with the connecting tube 3. A first corrugated tube 6, which can move and extend, is provided inside the control tube 5. A first pressing rod 7 is provided inside the first corrugated tube 6. The regulator 1 includes an overpressure rod 8 located inside the temperature sensing bulb 2.

[0031] The temperature sensing bulb 2 is existing technology, containing a medium that expands or contracts according to temperature. When the temperature changes, the medium inside the temperature sensing bulb expands or contracts, thereby changing the expansion and contraction state of the first bellows 6 and the second bellows 21. In this embodiment, the medium inside the temperature sensing bulb 2 is liquid, preferably ethyl acetate.

[0032] The first pressing rod 7 is circumferentially sleeved with a first return spring 9 located inside the first bellows 6.

[0033] The outer side of the temperature sensing bulb 2 is provided with a first threaded plate 10. The regulator 1 includes a second threaded plate 11 that is threadedly connected to the first threaded plate 10. An annular plate 12 is integrally connected to the inner side of the second threaded plate 11. A circular plate 13 is sleeved on the annular plate 12. A top plate 14 is engaged with the circular plate 13. A first locking block 15 is integrally connected to the inner side of the circular plate 13. A first locking plate 16 that engages with the first locking block 15 is integrally connected to the top plate 14. The circular plate 13 is connected to the overpressure rod 8.

[0034] The first threaded plate 10 is provided with a plurality of slots 17 at intervals, the circular plate 13 is integrally connected with a locking rod 18 located in the slot 17, and the top plate 14 is provided with an identifier 19 on its upper side.

[0035] A first support ring 20 is provided on the inner side of the first threaded plate 10.

[0036] The overpressure rod 8 is connected to the second threaded plate 11. The part of the overpressure rod 8 inside the temperature sensing bulb 2 is provided with a second bellows 21. The overpressure rod 8 is provided with a second return spring 22 inside.

[0037] The overpressure rod 8 is provided with a receiving groove 23 for accommodating the second return spring 22. The side of the overpressure rod 8 is provided with a through groove 24 communicating with the receiving groove 23. The overpressure rod 8 is provided with a stabilizing rod 25 located in the through groove 24.

[0038] Working principle:

[0039] The rotation regulator 1 drives the overpressure rod 8 to move up and down. With the downward movement of the overpressure rod 8, the space in the compressed temperature bag 2 becomes smaller, thereby transmitting the liquid to the control pipe 5 through the connecting pipe 3, and moving the first pressing rod 7 downward, thereby achieving the control purpose by the first pressing rod 7. The first pressing rod 7 moves the first bellows 6 when moving, so that the movement of the first pressing rod 7 will not cause the leakage problem.

[0040] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
