Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a quick-detachable PM2.5 detection device. Background Art

[0002] PM2.5 refers to ultrafine suspended particles in the atmosphere (particles with a diameter of 2.5 microns), also known as respirable particles, because they can be suspended in the air or float around with the air flow, and are easily adsorbed by toxic and harmful substances such as heavy metals and microorganisms. They also stay in the atmosphere for a long time and are transported over long distances, and therefore have a greater impact on human health and the quality of the atmospheric environment.

[0003] Most PM2.5 detection devices are fixedly installed in designated locations. However, due to long-term use, certain errors in PM2.5 detection are inevitable. Therefore, workers are generally required to perform regular maintenance on them. It takes a lot of time to remove general PM2.5 detection devices from the mounting base, and they do not have the effect of quick dismantling. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a quick-detachable PM2.5 detection device to solve the problem that most of the PM2.5 detection devices mentioned in the above background technology are fixedly installed at a specified position, but due to long-term use, it is inevitable that there will be certain errors in the detection of PM2.5, so workers are generally required to perform regular maintenance on it. It takes a lot of time to remove the general PM2.5 detection device from the mounting base, and it does not have the effect of quick disassembly.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick-detachable PM2.5 detection device, comprising a mounting seat, a detection box is arranged in the mounting seat, a connecting block is fixedly installed on the rear end surface of the detection box, four positioning holes are fixedly installed on the mounting seat, and the four positioning holes are arranged in a rectangular array on the surface of the mounting seat, a limiting plate is arranged in the middle position of the surface of the mounting seat, a slot is provided in the limiting plate, the shape of the slot is consistent with the shape of the connecting block arranged at the rear end of the detection box, and the connection block and the slot cooperate with each other to enable the detection box to be installed in the mounting seat.

[0006] By adopting the above technical solution, the connecting block set at the rear end of the detection box is inserted into the slot opened in the limit plate, and then the limit plate can limit the detection box, and then the detection box is adjusted to a suitable position. After the detection box is adjusted to a suitable position, the positioning bolt is inserted into the limiting hole, and then the positioning bolt is rotated clockwise so that the positioning bolt is inserted into the mounting base to fix the detection box. Then the four positioning holes opened on the mounting base can enable the PM2.5 detection device to be installed on the wall or outdoor where detection is required.

[0007] Preferably, a plurality of limiting holes are fixedly mounted on both side surfaces of the limiting plate, the plurality of limiting holes are arranged in a linear array on the surface of the limiting plate, and positioning bolts are inserted into the limiting holes.

[0008] By adopting the above technical solution, the position of the detection box can be adjusted through the limiting holes provided on the two side surfaces of the limiting plate, and the detection box can be fixed by cooperating with the positioning bolts.

[0009] Preferably, an air inlet is provided at the top of the detection box, an air outlet is provided at the bottom of the detection box, and an air inlet fan for supplying air into the detection box is provided in the air inlet.

[0010] By adopting the above technical solution, the air intake fan is turned on, and then the air intake fan allows the external air to enter the detection box through the air inlet, and then when the external air detection is completed, it will be discharged through the air outlet.

[0011] Preferably, a PM2.5 sensor capable of detecting PM2.5 values ​​is disposed on one inner wall of the detection box, and a wireless transmitter is disposed on the left inner wall of the detection box.

[0012] By adopting the above technical solution, the PM2.5 content in the air will be detected by the PM2.5 sensor to detect whether the PM2.5 content exceeds the standard. If the PM2.5 content in the air exceeds the standard, the PM2.5 sensor will send a signal to the wireless transmitter. After the wireless transmitter receives the signal, it will transmit information to the wireless device to remind the detection personnel.

[0013] Preferably, a slot is provided in the detection box at a position closer to the bottom, a filter element is inserted into the slot, and a handle is fixedly mounted on the outer end surface of the filter element.

[0014] By adopting the above technical solution, some particles in the air can be filtered through the filter element, and then after the filter element has been filtering for a long time, the filter element can be pulled out of the slot through the handle installed on the outer surface of the filter element, so as to clean and replace it.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The quick-detachable PM2.5 detection device rotates the positioning bolt counterclockwise to remove it from the limiting hole. Then, when the detection box is no longer restricted by the positioning bolt, it can slide upward or downward to allow the connecting block to drive the detection box out of the slot, so that the staff can quickly dismantle the detection device, so that the staff can better maintain and repair the PM2.5 detection device later.

[0017] 2. The quick-detachable PM2.5 detection device uses a filter element to filter some particles in the air inside the detection box. After the filter element has been filtering for a long time, the filter element can be pulled out of the slot through the handle installed on the outer surface of the filter element to clean and replace it.
