[0001] The utility model relates to the technical field of temperature sensing detectors, in particular to a temperature sensing detector with high sensitivity. Background Art

[0002] The combustion of materials during a fire generates a large amount of heat, causing the surrounding temperature to change. A temperature detector is a fire detector that responds to changes in the surrounding temperature of a certain point or line in the warning range. It converts temperature changes into electrical signals to achieve the purpose of alarm.

[0003] Existing sensor detectors lack effective protection against flying catkins and mosquitoes during daily use. These tiny objects in nature may adhere to the sensing components of the detector, causing the sensor to be blocked, thereby affecting its sensitivity to temperature changes and even misleading the detector to send out false alarm messages. Utility Model Content

[0004] The technical problem to be solved by the utility model is that in the prior art, the temperature sensing detector is easily disturbed by flying catkins and mosquitoes, and the sensor is blocked due to insufficient protection, which affects the temperature sensitivity and accurate alarm. For this reason, we propose a temperature sensing detector with high sensitivity.

[0006] Preferably, a sealing ring is installed on a side of the protective net away from the connecting seat.

[0007] Preferably, a circular bump is installed on one side of the detector body close to the connecting seat, and a sealing groove for use with the sealing ring is provided on one side of the circular bump close to the sealing ring.

[0008] Preferably, a plurality of second through holes are formed on the surface of the connecting seat.

[0009] Preferably, a guide block is installed inside the boss, the number of the guide blocks is two, and a second through groove for use with the guide block is formed on the surface of the transmission block.

[0010] Preferably, a limit spring is sleeved on the surface of the control rod, one end of the limit spring is fixedly connected to the second U-shaped block, and one end of the limit spring away from the second U-shaped block is fixedly connected to the boss.

[0011] Technical effects and advantages of the utility model:

[0012] In the utility model, the second through hole opened on the surface of the connecting seat and the protective net are used in cooperation to intercept flying catkins and mosquitoes, preventing them from adhering to the sensing component of the sensor, thereby improving the sensitivity to temperature changes.

At the same time, the sliding connection between the boss 5 and the first through hole 6 is used to facilitate the user to install the connecting seat 2, and then the connecting seat 2 is limited by the limiting component, so that the user can regularly maintain the connecting seat 2, clean the flying catkins and mosquito corpses attached to the surface, and prevent blockage. The control block 15 is pulled to make the control rod 14 drive the second U-shaped block 13 to move, and the movement of the second U-shaped block 13 drives the connecting rod 12, so that the connecting rod 12 is connected to the first U-shaped block 11 through rotation, and drives the transmission block 10. The fixed block 9 is driven by the transmission block 10 to disengage from the inner diameter of the first through groove 8 to release the limit of the connecting seat 2, so that it is convenient for the user to remove the connecting seat 2 and the protective net 3. The second through hole 7 on the surface of the connecting seat 2 is cleaned to prevent blockage. After cleaning, the connecting seat 2 is installed to the surface of the detector body 1 through the sliding connection between the boss 5 and the first through hole 6, and then the control block 15 is pushed to make the control rod 14 drive the second U-shaped block 13 to move the connecting rod 12, and the transmission block 10 drives the fixed block 9 to be inserted into the inner diameter of the first through groove 8 through the connecting rod 12, thereby limiting the position of the connecting seat 2.

When the transmission block 10 is moving, the movement trajectory of the transmission block 10 is guided and limited by the cooperation of the guide block 17 and the second through groove 18 to prevent deviation.

[0023] Working principle: the user pulls the control block 15 to make the control rod 14 drive the second U-shaped block 13 to move, and the movement of the second U-shaped block 13 drives the connecting rod 12, so that the connecting rod 12 is connected with the first U-shaped block 11 through rotation, and drives the transmission block 10 to move. When the transmission block 10 is moving, the guide block 17 and the second through groove 18 are used in conjunction to guide and limit the movement trajectory of the transmission block 10 to prevent deviation. The fixed block 9 is driven by the transmission block 10 to disengage from the inner diameter of the first through groove 8 to release the limit on the connecting seat 2, so that the user can remove the connecting seat 2, clean the protective net 3 and the second through hole 7 on the surface of the connecting seat 2 to prevent blockage, and after cleaning, the connecting seat 2 is connected to the detector through the sliding connection of the boss 5 and the first through hole 6. The surface of the main body 1, and then push the control block 15, so that the control rod 14 drives the second U-shaped block 13 to move the connecting rod 12, and through the connecting rod 12, the transmission block 10 drives the fixed block 9 to be inserted into the inner diameter of the first through groove 8, thereby limiting the position of the connecting seat 2. After the fixed block 9 limits the connecting seat 2, the elastic force generated by the limiting spring 16 limits the position of the second U-shaped block 13 to prevent the second U-shaped block 13 from moving due to non-human factors, causing the fixed block 9 to be disengaged from the inner diameter of the first through groove 8, causing the connecting seat 2 to fall off, and the shape of the protective net 3 is determined by the sealing ring 4. When the connecting seat 2 is installed on one side of the detector body 1, the sealing ring 4 is clamped with the sealing groove 20 to play a sealing role to prevent the entry of flying catkins and mosquitoes.
