[0031] The technical solution of the present invention is described below in conjunction with the accompanying drawings and embodiments.

[0032] like Figures 1 to 10 As shown, a wall-mounted thermostat with a temperature compensation resistor described in the present invention is applied to the temperature control of a heating device 9, comprising a thermostat body 1, on which a temperature compensation resistor 2, a mechanical switch 3 and a temperature switch 4 are arranged, the temperature switch 4 comprises a push rod 41, a moving contact piece 42, a stationary contact piece 43 and a temperature sensing piece 10, when the contact points of the moving contact piece 42 and the stationary contact piece 43 are in contact, the heating circuit is turned on, the two ends of the push rod 41 are respectively connected to the temperature sensing piece 10 and the moving contact piece 42, when the heating reaches the set temperature, the temperature sensing piece 10 suddenly jumps and drives the push rod 41 to push the moving contact piece 42 to separate from the stationary contact piece 43, and the heating circuit is disconnected; the temperature compensation resistor 2 is electrically connected to the stationary contact piece 43, the temperature compensation resistor 2 and the temperature sensing piece 10 are correspondingly arranged, and are used to compensate the temperature of the temperature sensing piece 10; the mechanical switch 3 is used to manually control the heating circuit to be turned on or off.

[0033] At present, the wall-mounted thermostat products on the market do not have a temperature compensation resistor 2, and are usually composed of a mechanical switch 3 and a temperature switch 4. After the circuit is turned on, the heating device 9 heats up. When the heating reaches the set temperature, the temperature sensing piece 10 jumps and drives the push rod 41 to push the moving contact piece 42 to separate from the static contact piece 43, the heating circuit is disconnected, and the heating device 9 stops heating. When the indoor temperature drops to a certain temperature, the temperature sensing piece 10 resets, driving the push rod 41 to pull the contact points of the moving contact piece 42 and the static contact piece 43 to re-contact, and reheat, and so on. However, such a structure has a low accuracy, and for long-distance temperature measurement, the time for the temperature to be transmitted to the temperature sensing piece 10 is long, and the error is large, resulting in lower temperature control accuracy and unreliable temperature regulation.

[0034] To solve this technical problem, the present invention makes further improvements on the prior art. Specifically, Figures 2 to 4 As shown, by adding a temperature compensation resistor 2, after the circuit is turned on (that is, when the mechanical switch 3 and the temperature switch 4 are closed), the heating device 9 is heated, and at the same time, the temperature compensation resistor 2 will also generate heat to compensate the temperature to the temperature sensor 10, shortening the time for the ambient temperature to be transmitted to the temperature sensor 10, and making certain compensation for the long-distance ambient temperature transmission, making the temperature measurement more accurate, thereby solving the problem that the wall-mounted thermostat products in the prior art have low accuracy, and for long-distance temperature measurement, the time for the temperature to be transmitted to the temperature sensor 10 is long, the error is large, resulting in lower temperature control accuracy and unreliable temperature regulation.

[0035] Preferably, the reset temperature difference of the temperature sensor 10 is about 3°C. The heating device 9 can be set to make the room temperature rise within 0.5°C. The temperature sensor 10 rises by about 3°C ​​and trips under the action of the compensation temperature. The room temperature drops by 0.5°C. At this time, the temperature sensor 10 drops by about 3°C ​​and resets. Under the action of the temperature compensation resistor 2, the room temperature is kept constant within 0.5°C.

[0036] Furthermore, the thermostat body 1 is fixedly hung on the wall through a fixing pin, and a mounting hole 11 matching the fixing pin is provided on the thermostat body 1, and a limit assembly corresponding to the fixing pin is provided in the mounting hole 11; a wire 6 for connecting the power supply assembly 8 and the heating device 9 is provided on the thermostat body 1, and a protective assembly is provided outside the wire 6. In this way, the wall-mounted thermostat with a temperature compensation resistor is fixedly hung on the wall through the fixing pin and the mounting hole 11, which is more convenient and quick to install and disassemble than the cumbersome fixing method using bolts and screw holes in the prior art, saving labor, and making subsequent maintenance and installation and disassembly more convenient.

[0037] In actual application, during installation, the fixing pin is fixed on the wall, and then the wall-mounted thermostat with temperature compensation resistor is pushed into the wall through the installation hanging hole 11 and aligned with the fixing pin to hang the wall-mounted thermostat with temperature compensation resistor on the wall.

[0038] Furthermore, a receiving groove 511 is formed on the inner wall of the mounting hole 11, and the limiting assembly includes a limiting block 51 and a spring 54, the spring 54 is located between the limiting block 51 and the inner wall of the receiving groove 511, the first end of the limiting block 51 is slidably connected to the receiving groove 511, and the second end of the limiting block 51 extends out of the receiving groove 511 and is limited corresponding to the fixing pin. In this way, when assembling, the wall-mounted thermostat with temperature compensation resistor is pushed into the mounting hole 11 to align with the fixing pin, and the fixing pin contacts the limiting block 5 when being pushed in, and under the action of the thrust, the fixing pin pushes the limiting block 51 to compress the spring 54, so that the limiting block 51 retracts relative to the receiving groove 511, and when pushed into a certain position, the wall-mounted thermostat with temperature compensation resistor is released, and at this time, under the elastic force of the spring 54, the limiting block 51 is pushed to limit and lock the fixing pin, which can prevent the problem of loosening after long-term use.

[0039] Preferably, there are two mounting holes 11, and two sets of limiting components are arranged in each mounting hole 11, so that the fixing effect is more firm.

[0040] Furthermore, a guide rod 53 is fixed in the accommodating groove 1 511, and a guide groove 52 is provided on the limit block 51, and the guide groove 52 is slidably connected with the guide rod 53. In this arrangement, under the cooperation of the guide groove 52 and the guide rod 53, the limit block 51 slides linearly, and the sliding effect is more stable.

[0041] Furthermore, a locking groove 55 is provided on the inner wall of the accommodating groove 511, a sliding groove 58 is provided on the limiting block 51, elastic cotton 57 and a locking block 56 are provided in the sliding groove 58, the elastic cotton 57 is located between the locking block 56 and the inner wall of the sliding groove 58, the first end of the locking block 56 is slidably connected to the sliding groove 58, and the second end of the locking block 56 extends out of the sliding groove 58 and is locked in the corresponding position of the locking groove 55. In this way, the positioning block 51 is limited by the cooperation of the clamping block 56 and the clamping slot 1 55. On the one hand, it can prevent the positioning block 51 from slipping out of the receiving slot 1 511, and on the other hand, it can further improve the limiting locking effect of the fixing pin. Specifically, in the initial state, the clamping block 56 and the clamping slot 1 55 cooperate to lock. When the mounting hanging hole 11 is aligned with the fixing pin and pushed in, the fixing pin pushes the positioning block 51 to compress the spring 1 54. The movement of the positioning block 51 drives the clamping block 56 to compress the elastic cotton 57 and make the clamping block 56 slide out of the clamping slot 1 55. At this time, the clamping block 56 is limited by the inner wall of the receiving slot 1 511 under the action of the elastic cotton 57, which is equivalent to giving the positioning block 51 a side limiting force, which can further improve the limiting locking effect of the fixing pin. Figure 6 and Figure 7 As shown, the spring 1 54 gives a downward thrust to the limit block 5, and the elastic cotton 57 and the clamping block 56 give a lateral thrust to the limit block 51.

[0042] In actual application, the outer wall of the block 56 is an inclined surface, which is convenient for sliding out of the slot 55 under the action of force; elastic cotton 57 and the block 56 are respectively provided on both sides of the limit block 51. After the blocks 56 on both sides are out of the slot 55, they are respectively abutted against the inner walls on both sides of the accommodating groove 511, and the locking effect is more secure.

[0043] Further, a slider 59 is fixed on the block 56, a guide rod 510 is fixed in the slide groove 58, and the slider 59 is slidably connected with the guide rod 510. This arrangement allows the block 56 to slide linearly, and the sliding effect is more stable.

[0044] Further, the protection assembly includes a mounting sleeve 71 and a mounting cover 73, wherein the mounting sleeve 71 is fixed on the thermostat body 1, and the mounting cover 73 is detachably mounted on the mounting sleeve 71, and a protective cotton 1 72 corresponding to the wire 6 is provided on the inner wall of the mounting sleeve 71, and a protective cotton 2 74 corresponding to the wire 6 is provided on the inner wall of the mounting cover 73, and a locking assembly corresponding to the mounting cover 73 is provided on the mounting sleeve 71. In this way, the mounting sleeve 71 and the mounting cover 73 cooperate to protect the wire 6 and prevent the wire 6 from being damaged.

[0045] Furthermore, a connecting block 78 is fixed on the inner wall of the mounting cover 73, a connecting groove 77 corresponding to the connecting block 78 is provided on the mounting cover 73, a locking groove 79 is provided on the connecting block 78, a second accommodating groove 723 is provided on the mounting cover 73, and a locking assembly comprises a slide bar 710, a pull ring 713, a limiting ring 714, a second spring 719 and a sealing sleeve 720, the limiting ring 714 and the second spring 719 are arranged in the second accommodating groove 723, the sealing sleeve 720 is fixed on the opening of the second accommodating groove 723, the pull ring 713 is fixedly connected to the first end of the slide bar 710, the second end of the slide bar 710 passes through the sealing sleeve 720, the second spring 719 and the limiting ring 714 in sequence, and then extends out of the second accommodating groove 723 and is locked corresponding to the locking groove 79, the two ends of the second spring 719 abut against the inner wall of the second accommodating groove 723 and the limiting ring 714, and the limiting ring 714 is fixedly connected to the slide bar 710. With this arrangement, during assembly, the pull ring 713 is pulled to drive the slide rod 710 and the limit ring 714 to compress the spring 2 719, thereby making way for the assembly space of the connecting block 78. When the connecting block 78 is assembled in the connecting groove 77, the pull ring 713 is released, and the limit ring 714 and the slide rod 710 are pushed under the rebound force of the spring 2 719, so that the slide rod 710 extends out of the accommodating groove 2 723 and is locked corresponding to the locking groove 79.

[0046] Furthermore, the limiting ring 714 is fixed with a second slider 716, which is provided with a groove 717, and a ball 718 is provided in the groove 717, and the ball 718 is rollingly connected with the inner wall of the second receiving groove 723.
