[0028] Among them, the infrared temperature measuring component 200 can be a conventional infrared temperature measuring probe. The infrared rays radiated from the object enter the installation cavity 140 through the light-transmitting part and are acquired by the infrared temperature measuring component 200. The infrared temperature measuring component 200 forms an electrical signal, and the processor analyzes the electrical signal to obtain temperature data. The waterproof connector 160 can be made of elastic material, such as rubber, resin, etc. The waterproof connector 160 is elastically abutted against the inner circumferential wall of the wiring opening 150 and the outer circumferential wall of the wire, thereby reducing the gap between the inner circumferential wall of the wiring opening 150 and the outer circumferential wall of the wire.

[0029] The water inlet 320 and the water outlet 330 arranged on the shell assembly 100 can be equipped with water pipe joints, which can be connected to a water supply source or a water reservoir through a conduit. The water supply source can be provided with a water pump, which provides pressure for the water so that the water flows through the heat dissipation water channel 310, and the water reservoir can accommodate water carrying heat, which can then be cooled by a refrigeration device and then flow back to the water supply source to form a circulating water loop for heat dissipation.

The light-transmitting portion acquires infrared rays, thereby analyzing the temperature, and the heat generated by the operation of the infrared temperature measuring component 200 can be conducted to the housing assembly 100. The water inlet 320 is connected to an external water supply source, and the water is transmitted through the heat dissipation water channel 310 and is in full contact with the housing assembly 100. The heat will be transferred to the water, and the water carrying the heat will be discharged from the water outlet 330. This design provides a sealed detection environment for the infrared temperature measuring component 200 to prevent the invasion of water vapor and smoke, and dissipates heat in time to ensure the operating stability and detection accuracy of the infrared temperature measuring component 200.

[0031] In some embodiments of the present invention, the heat dissipation water channel 310 is arranged in a spiral shape and extends along the length direction of the installation cavity 140 , and the water inlet 320 is connected to the head end of the heat dissipation water channel 310 , and the water outlet 330 is connected to the tail end of the heat dissipation water channel 310 .

[0033] In some embodiments of the present invention, Figure 1 As shown, the housing assembly 100 opens an annular water cavity around the installation cavity 140 to define a heat dissipation water channel 310, and the water inlet 320 and the water outlet 330 are respectively located on the left and right sides relative to the installation cavity 140, and the water inlet 320 and the water outlet 330 are respectively located at the upper and lower ends of the water cavity.

The water inlet 320 and the water outlet 330 are respectively located on the left and right sides relative to the installation cavity 140 and also at the upper and lower ends of the water cavity, so that the water entering the water cavity has a longer flow distance and can fully exchange heat with the shell assembly 100.

[0035] In some embodiments of the present invention, a groove 340 is provided on the inner wall of the water cavity, and the groove 340 is arranged in a spiral shape and extends along the length direction of the installation cavity 140.

When used in a dusty scenario, there may be a lot of dust in front of the light-transmitting part, thereby preventing infrared rays from normally entering the installation cavity 140. Therefore, the air supply source is controlled to output gas, and the gas enters the gas delivery channel 410 from the air inlet 420 and is then ejected from the air outlet 430 to remove the dust in front of the light-transmitting part.

[0038] Specifically, the air outlet 430 is arranged around the light-transmitting portion, and the opening direction of the air outlet 430 is toward the front of the light-transmitting portion.

The air supply channel 410 is extended in the shell assembly 100, so as to supply air to the annular air outlet 430. Specifically, the air outlet 430 can be annular, so as to be arranged around the light-transmitting portion. There can also be multiple air outlets 430, and the multiple air outlets 430 are arranged around the light-transmitting portion, and each air outlet 430 is arranged with the air supply channel 410.

[0039] In some embodiments of the utility model, the sleeve shell assembly 100 includes a bottom shell 110 and a light-transmitting surface cover 120, the bottom shell 110 is sleeved on the light-transmitting surface cover 120 to enclose the installation cavity 140 and the light-transmitting surface cover 120 forms the light-transmitting portion, the heat dissipation water channel 310 and the wiring opening 150 are opened in the bottom shell 110, the bottom shell 110 is barrel-shaped, the light-transmitting surface cover 120 is arranged at the barrel mouth position, and the bottom shell 110 has a certain thickness, so that the heat dissipation water channel 310 can be opened inside.

The waterproof ring 130 can be made of rubber, resin and other materials. The waterproof ring 130 can be elastically pressed against the inner circumferential wall of the bottom shell 110 and the outer circumferential wall of the translucent surface cover 120, thereby preventing water vapor and dust from entering the installation cavity 140.

[0041] In some embodiments of the present invention, the shell assembly 100 is provided with a light-transmitting observation window 170, and the observation window 170 corresponds to the installation cavity 140. The user can see the situation inside the installation cavity 140 through the observation window 170 to know whether water has entered the installation cavity 140. When water has entered, timely repairs and replacements can be performed to prevent damage to components.

[0042] Specifically, the bottom of the bottom shell 110 may be inlaid with a tempered glass or acrylic panel to form an observation window 170 .

[0043] In some embodiments of the present invention, the water-cooled infrared temperature measuring device further includes a base 500 , on which a steering mechanism 600 is disposed.

The steering mechanism 600 can rotate the shell assembly 100 relative to the base 500, thereby adjusting the infrared temperature measuring component 200's infrared collection angle, which is equivalent to changing the position of the infrared temperature measuring component 200 toward the object to be measured, thereby detecting the temperature at different positions.

[0045] Specifically, the steering mechanism 600 may be a universal ball joint or other rotating shaft structures.
