Description

Technical Field

[0001] This utility model relates to the field of air detection equipment technology, specifically a cleanroom air detection device. Background Technology

[0002] Cleanrooms are widely used in semiconductor, pharmaceutical, and precision manufacturing industries. Their air cleanliness directly impacts product quality and production safety, thus requiring extremely high accuracy, real-time performance, and continuity in air monitoring. Existing cleanroom air monitoring devices mostly employ an integrated "sensor + circuit board" structure, but this has significant shortcomings in practical applications:

[0003] On the one hand, components such as detection probes and control chips generate a lot of heat when operating at high frequencies. Existing devices often have a single heat dissipation hole and lack targeted heat conduction components (such as heat sinks / heat plates). Heat cannot be dissipated quickly, and long-term high temperatures can lead to decreased sensor sensitivity, chip calculation errors, and in severe cases, even direct damage to components, significantly reducing the lifespan of the device.

[0004] On the other hand, cleanrooms have diverse installation scenarios (such as ceiling installation, wall installation, and equipment side installation). Existing installation structures have poor compatibility and often require additional custom installation accessories. Moreover, the outer shell of the device is mostly an integrated design, and the internal components need to be completely disassembled for maintenance, which is cumbersome. This not only increases installation and maintenance costs but also introduces external pollutants during the disassembly process, affecting the cleanroom environment. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a cleanroom air detection device with an efficient heat dissipation structure and a convenient installation and adaptation structure, which solves the problems of poor heat dissipation and inconvenient installation and maintenance of existing devices.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cleanroom air detection device, comprising a bottom shell assembly, an air detection assembly, and a top shell assembly. The air detection assembly is mounted on the bottom shell assembly, and the top shell assembly is connected to the bottom shell assembly. The bottom shell assembly includes a bottom shell housing, within which a connecting column is provided for supporting and fixing the air detection assembly. The air detection assembly includes a mounting base plate, which is connected to the bottom shell housing via the mounting column. A circuit board is mounted on the mounting base plate, and a control chip is mounted on the circuit board for processing air detection data. The circuit board is electrically connected to a gas sensor and a detection probe for collecting cleanroom air pollutant information. A control switch and a power supply interface are provided on the side of the bottom shell housing for power control and power input of the device. The top shell assembly includes a top shell housing, on which a connecting hole corresponding to the connecting column is provided, a first heat dissipation hole and a second heat dissipation hole for heat dissipation of the device, an adaptable mounting groove for improving installation compatibility, and a through hole for connecting the top shell and the bottom shell.

[0009] As a further improvement of this utility model: a heat sink is provided on the outside of the gas sensor, the heat sink is connected to the mounting base plate through a support member, and a fixing member is provided on the heat sink for mounting the gas sensor, which can quickly dissipate the heat of the gas sensor when it is working.

[0010] As a further improvement of this utility model, the gas sensor is a multi-parameter gas detection sensor that can simultaneously detect multiple air pollutants, such as particulate matter and harmful gases, to meet the multi-dimensional detection needs of cleanrooms.

[0011] As a further improvement of this utility model: the heat sink is made of aluminum, which has good thermal conductivity, and the detection probe is adapted to be installed in the adaptation mounting slot, which facilitates air collection and heat dissipation.

[0012] As a further improvement of this utility model, the top shell assembly and the bottom shell assembly are fixedly connected by bolts passing through the adapter mounting groove and the connecting column, which makes disassembly and assembly convenient and facilitates the maintenance of internal components.

[0013] As a further improvement of this utility model: the through hole can be adapted to different types of installation components for diverse installation in clean rooms, such as hanging, wall mounting, etc. The first heat dissipation hole and the second heat dissipation hole are respectively opened on the front and rear sides and the left and right sides of the top shell to form a heat dissipation channel, which, together with the heat sink, achieves efficient heat dissipation.

[0014] As a further improvement of this utility model, the control switch and power supply interface are electrically connected to the circuit board to realize the power control and data transmission of the device.

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

[0016] 1. In this utility model, by setting an aluminum heat sink to directly contact the detection probe and gas sensor, and in conjunction with the first and second heat dissipation holes distributed in three dimensions on the top shell, a three-level heat dissipation system of "component heat conduction - heat sink temperature conduction - multi-hole heat dissipation" is formed, which can quickly dissipate the heat of the detection component during operation and exchange it with the outside air, effectively avoiding heat accumulation.

[0017] 2. In this utility model, the overall detection device adopts an integrated design and has through holes on the top shell, which can accommodate various installation accessories such as hanging brackets and wall-mounted clips, meeting the installation needs of cleanroom ceilings, walls, and equipment side installations. At the same time, the top shell assembly and the bottom shell assembly are connected by bolts for detachment. During maintenance, only the corresponding bolts need to be removed to inspect the air detection component, without the need to disassemble the entire device. This simplifies the installation and maintenance process and avoids secondary pollution of the cleanroom environment caused by device disassembly and assembly, significantly improving the practicality of the device and the environmental protection of the cleanroom.

[0034] The working principle of this utility model is as follows: When in use, a power supply is connected through the power supply interface 211, and the control switch 210 is turned on. The gas sensor 25 and the detection probe 29 start to work, collecting cleanroom air data and transmitting it to the control chip 24 on the circuit board 23 for processing.
