Description

Technical Field

[0001] This utility model relates to the technical field of atmospheric particulate matter monitoring devices, specifically an atmospheric particulate matter monitoring device with a ventilation structure. Background Technology

[0002] Particulate matter with a diameter of less than 10 micrometers is generally referred to as PM10, also known as inhalable particulate matter or suspended particulate matter. The smaller the diameter of the particulate matter, the deeper it penetrates into the respiratory tract. Particulate matter with a diameter of 10 micrometers usually settles in the upper respiratory tract, while particles with a diameter of 5 micrometers can penetrate deep into the respiratory tract, and particles smaller than 2 micrometers can penetrate 100% into the bronchioles and alveoli.

[0003] According to the ventilation structure of an atmospheric particulate matter monitoring device disclosed in the above application (Announcement No.: CN219228281U), the cooling fan, heat dissipation vent, and ventilation opening can dissipate heat from the inside of the atmospheric particulate matter monitoring box; by setting a synchronous belt and dustproof holes, dust from the outside can be prevented. When dust is blocked in the dustproof holes, the first motor is driven, which drives the synchronous roller to rotate, thereby driving the synchronous belt transmission. The synchronous belt passes through a cleaning component, which cleans the dust adhering to the synchronous belt, realizing automatic cleaning of the synchronous belt. There is no need for manual disassembly and cleaning of the synchronous belt periodically, reducing the workload.

[0004] However, in actual use, the size of the filter holes in the above-mentioned devices is difficult to adjust. When gas containing atmospheric particles of different sizes is inhaled, if the filter holes are too large, the particles will not be detected sufficiently, and the particles will easily escape from the air outlet, making it difficult to detect the gas. In view of this, we propose an atmospheric particulate matter monitoring device with a ventilation structure. Utility Model Content

[0005] The purpose of this invention is to provide an atmospheric particulate matter monitoring device with a ventilation structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an atmospheric particulate matter monitoring device with a ventilation structure, comprising a housing, a cabinet door rotatably connected to the outer wall of the housing, a handle fixedly connected to the outer wall of the cabinet door, an air outlet on the outer wall of the housing, a filter cartridge fixedly connected to the upper outer wall of the housing, a sampling head provided on the upper outer wall of the filter cartridge, a fan disposed inside the housing, and an adjustment component inside the housing to prevent atmospheric particles from being discharged from the air outlet, the adjustment component comprising: The motor is fixedly connected to the outer wall of the housing. The output end of the motor passes through the outer wall of the housing and is fixedly connected to a rotating rod. The outer wall of the rotating rod is fixedly connected to a driving bevel gear, and the outer wall of the driving bevel gear meshes with a transmission bevel gear. A connecting rod is fixedly connected to the lower outer wall of the transmission bevel gear. A lead screw is fixedly connected to the lower outer wall of the connecting rod. A slide is driven by the lead screw. A filter plate is fixedly connected to the outer wall of the slide.

[0007] Preferably, the interior of the housing is provided with a cleaning assembly for cleaning the filter plates. The cleaning assembly includes a cleaning block, which is fixedly connected to the inner wall of the housing. The inner wall of the housing has a dust collection groove, and the outer wall of the housing is slidably connected to the dust collection box through it, so that when switching different air outlet filter plates, the cleaning block can clean the filter plates.

[0008] Preferably, cleaning blocks are fixedly connected to the inner walls of both the upper and lower ends of the air outlet. The cleaning blocks contact the outer wall of the filter plate so that when the filter plate moves up and down, the brushes on the cleaning blocks can sweep the filter holes on the filter screen.

[0009] Preferably, the outer wall of the outer shell has a through-hole storage groove, the dust collection box is slidably connected to the inner wall of the storage groove, and the lower outer wall of the lower dust groove is connected to the upper outer wall of the storage groove, so that the dust swept off the filter plate can fall into the dust collection box from the lower dust groove, making it difficult for the swept dust to move to the air outlet.

[0010] Preferably, both the rotating rod and the lead screw are rotatably connected to the inner wall of the housing, and both ends of the rotating rod are provided with active bevel gears, so that the filter plates on the air outlets at both ends of the housing can move simultaneously, so that the filter holes of the filter plates at both ends of the air outlet are the same size.

[0011] Preferably, the filter plate consists of three sets of filter screens with filter holes of different diameters. The length of the lead screw is the same as the length of one set of filter screens. The motor drives the rotating rod to rotate the active bevel gear, which in turn drives the transmission bevel gear to rotate. The transmission bevel gear then drives the connecting rod to rotate the lead screw. At this time, the slide moves the filter plate, changing the filter screen at the air outlet.

[0012] Preferably, the size of the air outlet is the same as the size of the filter plate, and the midpoint of the lead screw is flush with the midpoint of the air outlet, so that the filter plate can fully block the air outlet and allow atmospheric particles to be blocked by the filter plate.

[0013] Compared with the prior art, the present invention provides an atmospheric particulate matter monitoring device with a ventilation structure, which has the following beneficial effects:

[0014] 1. This atmospheric particulate matter monitoring device with a ventilation structure uses a motor to drive a rotating rod to rotate an active bevel gear, which in turn drives a transmission bevel gear to rotate a connecting rod that drives a lead screw. At this time, the slide moves the filter plate, allowing the filter plates at the air outlets at both ends of the housing to be changed to accommodate atmospheric particles of different diameters. This ensures that while the air outlets can ventilate, atmospheric particles are not easily escaped, thus enabling the device to perform sufficient detection.

[0015] 2. This atmospheric particulate matter monitoring device with ventilation structure can have its brushes on the cleaning block sweep the filter holes on the filter screen when switching between different air outlet filter plates, so that the dust on the filter plate will fall into the dust collection box for easy collection and cleaning.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: an atmospheric particulate matter monitoring device with a ventilation structure, including a shell 1, a cabinet door 2 rotatably connected to the outer wall of the shell 1, a handle 3 fixedly connected to the outer wall of the cabinet door 2, an air outlet 4 opened on the outer wall of the shell 1, a filter cartridge 5 fixedly connected to the upper outer wall of the shell 1, a sampling head 6 provided on the upper outer wall of the filter cartridge 5, a fan 7 provided inside the shell 1, and an adjustment component 8 provided inside the shell 1 to prevent atmospheric particles from being discharged from the air outlet 4. The adjustment component 8 includes: Motor 81 is fixedly connected to the outer wall of housing 1. The output end of motor 81 passes through the outer wall of housing 1 and is fixedly connected to rotating rod 82. The outer wall of rotating rod 82 is fixedly connected to driving bevel gear 83. The outer wall of driving bevel gear 83 is meshed with transmission bevel gear 84. A connecting rod 85 is fixedly connected to the lower outer wall of the transmission bevel gear 84. A lead screw 86 is fixedly connected to the lower outer wall of the connecting rod 85. A slide 87 is driven by the lead screw 86. A filter plate 88 is fixedly connected to the outer wall of the slide 87.

[0022] In one embodiment of this utility model, a motor 81 is fixedly connected to the outer wall of the housing 1. The output end of the motor 81 passes through the outer wall of the housing 1 and is fixedly connected to a rotating rod 82. An active bevel gear 83 is fixedly connected to the outer wall of the rotating rod 82, and a transmission bevel gear 84 meshes with the outer wall of the active bevel gear 83.

[0023] In one embodiment of this utility model, the connecting rod 85 is fixedly connected to the lower outer wall of the transmission bevel gear 84, the lower outer wall of the connecting rod 85 is fixedly connected to the lead screw 86, the lead screw 86 is driven by the slide block 87, and the outer wall of the slide block 87 is fixedly connected to the filter plate 88.

[0024] In addition, the interior of the outer casing 1 is provided with a cleaning component 9 for cleaning the filter plate 88. The cleaning component 9 includes a cleaning block 91, which is fixedly connected to the inner wall of the outer casing 1. The inner wall of the outer casing 1 is provided with a dust groove 92, and the outer wall of the outer casing 1 is slidably connected to a dust collection box 93. When switching the filter plates 88 of different air outlets 4, the cleaning block 91 can clean the filter plates 88, so that the dust adhering to the filter plates will fall into the dust collection box 93 for easy collection and cleaning.

[0025] In the embodiments of this utility model, cleaning blocks 91 are fixedly connected to the inner walls of both the upper and lower ends of the air outlet 4. The cleaning blocks 91 contact the outer wall of the filter plate 88 so that when the filter plate 88 moves up and down, the brush on the cleaning blocks 91 can sweep the filter holes on the filter screen plate 88, so that the dust in the filter holes on the filter plate 88 can be swept off.

[0026] In an embodiment of this utility model, the outer wall of the outer shell 1 is provided with a through storage groove, the dust collection box 93 is slidably connected to the inner wall of the storage groove, and the lower outer wall of the lower dust groove 92 is connected to the upper outer wall of the storage groove, so that the dust swept off the filter plate 88 can fall from the lower dust groove 92 into the dust collection box 93, making it difficult for the swept dust to move from the air outlet 4, thus making it easy to clean the dust.

[0027] In the embodiments of this utility model, the rotating rod 82 and the lead screw 86 are both rotatably connected to the inner wall of the outer casing 1. Both ends of the rotating rod 82 are provided with active bevel gears 83, so that the filter plates 88 on the air outlets 4 at both ends of the outer casing 1 can move simultaneously, so that the filter holes of the filter plates 88 at both ends of the air outlets 4 are the same size, preventing atmospheric particles from being blocked from one side of the air outlet 4 and discharged from the other side of the air outlet 4.

[0028] In this embodiment of the utility model, the filter plate 88 is composed of three sets of filter screen plates with filter holes of different diameters. The length of the lead screw 86 is the same as the length of one set of filter screen plates. The motor 81 drives the rotating rod 82 to rotate the active bevel gear 83, which in turn drives the transmission bevel gear 84 to rotate. In turn, the transmission bevel gear 84 drives the connecting rod 85 to rotate the lead screw 86. At this time, the slide 87 drives the filter plate 88 to move, which changes the filter screen plate at the air outlet 4. While allowing ventilation, it makes it difficult for atmospheric particles to escape.

[0029] In this embodiment of the invention, the size of the air outlet 4 is the same as the size of the filter plate, and the midpoint of the lead screw 86 is flush with the midpoint of the air outlet 4, so that the filter plate can fully block the air outlet 4, and the atmospheric particles can be blocked by the filter plate, thereby enabling the device to perform sufficient detection.

[0030] In this invention, during use, gas enters through the sampling head 6 and filter cartridge 5. Driven by the fan 7, it passes through the air outlet 4 to screen out atmospheric particles for easy detection. When dealing with atmospheric particles of different diameters, the motor 81 drives the rotating rod 82 to rotate the active bevel gear 83, which in turn drives the transmission bevel gear 84, causing the connecting rod 85 to rotate the lead screw 86. At this time, the slide 87 moves the filter plate 88, allowing the filter plates at the air outlets 4 at both ends of the outer casing 1 to be changed to accommodate atmospheric particles of different diameters. This ensures that while the air outlet 4 can ventilate, atmospheric particles are less likely to escape, allowing the device to perform thorough detection. When switching between different air outlet 4 filter plates 88, the brush on the cleaning block 91 can sweep the filter holes on the filter plate 88, causing the dust adhering to the filter plate to fall into the dust collection box 93 for easy collection and cleaning.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
