[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] Reference Figure 1-Figure 4 , a thermostat with an alarm function, comprising a housing 1, wherein a trigger component is provided inside the housing 1;

[0031] The trigger assembly includes a driving component and an adjusting component. The driving component includes an expansion block 5. A push plate 6 is provided on one side of the expansion block 5. An L-shaped rod 10 is fixedly connected to one side of the push plate 6. An end of the L-shaped rod 10 away from the push plate 6 is fixedly connected to a connecting rod 11.

[0032] The expansion block 5 is made of nylon. Alternatively, the expansion block 5 may also be made of rubber.

[0033] By setting the trigger component, the buzzer can be triggered to alarm when the environment is at high temperature, helping staff to quickly assess the situation and take corresponding cooling measures more promptly.

[0034] Reference Figure 3-Figure 4 The adjusting component includes a sliding resistor 14, a contact piece 13 is fixedly connected to the bottom of the slider 12 on the sliding resistor 14, one end of the slider 12 is fixedly connected to the connecting rod 11, a placement box 4 is fixedly connected to the inside of the shell 1, the expansion block 5 is located inside the placement box 4, and the push plate 6 is slidably connected to the placement box 4.

[0035] By adjusting the setting of the components, when the expansion block 5 expands due to heat, its volume becomes larger, which pushes the push plate 6 to move to one side of the placement box 4, and then pushes the contact piece 13 under the slider 12 to move to one side on the sliding resistor 14, so that the resistance inside the buzzer 15 becomes smaller. The reduction in resistance value will cause the current to increase, thereby increasing the sound of the buzzer 15. The volume of the buzzer 15 is controlled according to the change in temperature.

[0036] Reference Figure 3-Figure 4 Two fixed plates 9 are provided inside the expansion block 5, and one end of the two fixed plates 9 close to the push plate 6 is fixedly connected to a spring 8, and one end of the spring 8 away from the fixed plate 9 is fixedly connected to a trigger member 7, and the two trigger members 7 are slidably connected to the placement box 4.

[0037] When the push plate 6 moves to one side, the push plate 6 will contact the trigger member 7, and the controller 16 will control the buzzer 15 to work, reminding people that the external environment temperature is too high, prompting them to take measures to prevent the equipment from being damaged.

[0038] Reference Figure 3-Figure 4 A buzzer 15 is provided inside the housing 1 , and the buzzer 15 is electrically connected to the sliding resistor 14 . A controller 16 is provided inside the housing 1 , and the controller 16 is electrically connected to the trigger member 7 and the buzzer 15 .

[0039] By adjusting the resistance inside the sliding resistor 14, the current inside the buzzer 15 can be adjusted to adjust the volume of the buzzer 15. The buzzer 15 and the sliding resistor 14 are both supplied with current by an external power supply.

[0040] When the trigger member 7 contacts the push plate 6 , the trigger member 7 transmits a signal to the controller 16 because the trigger member 17 is electrically connected to the controller 16 , and the controller 16 controls the buzzer 15 to start operating.

[0041] Reference Figure 1-Figure 2 A connecting plate 2 is provided on the rear side of the body 1, and a heat dissipation plate 3 is provided inside the connecting plate 2.

[0042] The heat sink 3 can dissipate heat, and the heat sink 3 adopts a detachable structure (which is a clamping or bolting connection in the prior art), and can be disassembled and cleaned when the heat sink 3 is damaged or needs to be cleaned.

[0043] Working principle: When in use, first fix the shell 1 and then use the device to work. When the temperature of the monitored environment is too high, the expansion block 5 will begin to expand due to the heat. When the expansion block 5 expands, it will squeeze the push plate 6 on one side to move. When the push plate 6 moves, it first contacts the trigger member 7, and then squeezes the spring 8. When the trigger member 7 contacts the push plate 6, the controller 16 will control the buzzer 15 to start, and then drive the connecting rod 11 to move to the right through the push plate 6, and then push the contact piece 13 under the slider 12 to move to one side on the sliding resistor 14, so that the resistance inside the buzzer 15 becomes smaller. The reduction in resistance value will cause the current to increase, thereby increasing the sound of the buzzer 15. When the ambient temperature is higher, the volume of the buzzer 15 will be louder, indicating that the temperature rise is more serious, which helps the staff to quickly assess the environmental conditions and judge the need to take corresponding heat dissipation measures based on the volume.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
