Description

Technical Field

[0001] This invention belongs to the field of particle sensor technology, and more specifically, relates to a high-temperature resistant particle sensor. Background Technology

[0002] Particle sensors are devices that can detect and measure various particles in the environment (such as dust particles, smoke, pollen, microorganisms, etc.) and play an important role in many fields.

[0003] Existing particle sensors require long pipes to passively cool the gas within the detection instrument when handling high-temperature gases, preventing damage. However, excessive pipe length leads to dust adhering to the pipe's inner wall, resulting in a lower sample particle count and reduced gas flow rate, thus causing inaccurate sampling. Therefore, this paper researches and improves upon existing structures and shortcomings to provide a high-temperature resistant particle sensor with greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-temperature resistant particle sensor, which is achieved by the following specific technical means:

[0005] A high-temperature resistant particle sensor includes a detection instrument. A supporting bracket is mounted on one side of the detection instrument, and a cooling device is mounted on one side of the supporting bracket. The cooling device includes a fixing frame, which is fixedly mounted on one side of the supporting bracket by fasteners. A heat dissipation duct is provided on the supporting bracket, and a cooling fan is mounted on one side of the heat dissipation duct. A heat dissipation copper pipe is installed between the fixing frame and the supporting bracket, and the heat dissipation copper pipe is arranged corresponding to the heat dissipation duct. A cooling pipe is installed on one side of the supporting bracket, and a cavity is provided inside the cooling pipe. Both ends of the heat dissipation copper pipe are fixedly connected to the cooling pipe, and the inner side of the heat dissipation copper pipe is connected to the cavity. An air inlet and an air outlet are respectively provided at both ends of the cooling pipe, and the air outlet is connected to the detection instrument through a connecting hose.

[0006] Furthermore, a high-temperature resistant hose is connected to the air inlet.

[0007] Furthermore, a high-temperature sensor is connected to the outer side of the high-temperature resistant hose.

[0008] Furthermore, a humidity sensor is fixedly installed on one side of the detection instrument.

[0009] Furthermore, two sets of connecting seats are symmetrically fixedly installed on both sides of the supporting bracket.

[0010] Furthermore, the testing instrument is fixedly connected to the matching bracket via fasteners.

[0011] Furthermore, the cooling fan is fixedly connected to the mounting bracket by fasteners.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention utilizes a combination of a cooling fan and a heat dissipation duct to cool the heat dissipation copper tube. The combination of the copper tube and the cooling pipe allows for active cooling of high-temperature gas passing through the cooling pipe, preventing damage to the testing instrument. It also avoids the need for excessively long pipes to cool the gas, preventing dust particles from adhering to the inner wall of the pipe and causing inaccurate test results, thus increasing the product's practicality.
