[0025] A dual-flow dust particle counter, comprising

[0026] The base 1 has a buffer component fixedly connected to the inner wall of the base 1, and the buffer component includes a telescopic rod 2, a fixed plate 3, a rotating rod 4, a movable plate 5 and a buffer plate 6. One end of the telescopic rod 2 is fixedly connected to the inner wall of the base 1, and one side of the surface of the telescopic rod 2 is fixedly connected to the fixed plate 3. The fixed plate 3 is rotatably connected to the rotating rod 4. The outer surface of the rotating rod 4 is clamped with the movable plate 5, and the top of the movable plate 5 is fixedly connected to the buffer plate 6. The buffer plate 6 is pressed downward by the weight of the counter, driving the movable plate 5 to move downward. Because the movable plate 5 is provided with a reserved slot hole inside, it will drive the rotating rod 4 to move to both sides in the reserved slot hole, and then drive the fixed plate 3 to one side on both sides. The movement of the fixed plate 3 drives the telescopic rod 2 to retract inwardly. The telescopic rod 2 is slightly tilted downward in a normal state, and the interior is hollow, thereby buffering the counter, thereby achieving the effect of increasing the service life of the device, avoiding the situation that the internal components of the counter are easily damaged due to collision when the counter is placed, affecting normal use, and reducing the service life of the device;

[0027] A rotating assembly is fixedly connected to one side of the top of the base 1, a particle sampler 7 is fixedly connected to the inner side wall of the rotating assembly, a dustproof assembly is fixedly connected to one side of the surface of the particle sampler 7, and the dustproof assembly includes a connecting line 8, a dustproof frame 9, a connecting piece 10 and a cover plate 11. One end of the connecting line 8 is fixedly connected to one side of the surface of the particle sampler 7, and the other end of the connecting line 8 is fixedly connected to the dustproof frame 9. The top of one end of the dustproof frame 9 is fixedly connected to the connecting piece 10, and the surface side of the connecting piece 10 is fixedly connected to the cover plate 11. The connecting line 8 connects and fixes the dustproof frame 9. Since a strip slot is provided at the bottom of the dustproof frame 9, the operator can cover the dustproof frame 9 from the front of the sampler on the surface of the sampler. The connecting piece 10 supports and fixes the cover plate 11, which can drive the upper and lower cover plates 11 to flip, and effectively prevent dust from forming on the surface of the sampler, thereby achieving the effect of improving the sampling efficiency of the sampler, and avoiding the accumulation of dust on the surface of the device after being placed for a long time when it is not needed, and the dust affects the subsequent normal use of the sampler, thereby reducing the sampling efficiency of the sampler.

[0028] The top of the buffer plate 6 is clamped with a particle counter 12, and the top of the particle counter 12 is fixedly connected with a taking component;

[0029] In this embodiment, preferably, the rotating assembly includes a fixed ring 13, an arc-shaped slide groove 14 and a connecting ring 15. The bottom of the fixed ring 13 is fixedly connected to the top side of the base 1. The inner wall of the fixed ring 13 is provided with an arc-shaped slide groove 14. The inner wall of the arc-shaped slide groove 14 is clamped with the connecting ring 15. The fixed ring 13 is made of rubber. When the operator clamps the connecting ring 15 into the arc-shaped slide groove 14, the particle sampler 7 can be driven to rotate to sample dust particles in all directions.

[0030] In this embodiment, preferably, the picking assembly includes a handle 16 and an anti-skid pad 17. The bottom of the handle 16 is fixedly connected to the top of the particle counter 12. The outer surface of the handle 16 is fixedly connected to the anti-skid pad 17. The arrangement of the handle 16 facilitates the picking up and placing of the particle counter 12. The anti-skid pad 17 is anti-skid. Through the connection with the handle 16, the picking device is not easy to slip.

[0031] In this embodiment, preferably, a transmission line 18 is fixedly connected to the top of the particle counter 12, and one end of the transmission line 18 is fixedly connected to the outer surface of the particle sampler 7;

[0034] When a dual-flow dust particle counter of the present embodiment is in use, the buffer plate 6 is pressed downward by the weight of the counter, driving the movable plate 5 to move downward. Since a reserved slot is provided inside the movable plate 5, the rotating rod 4 will be driven to move to both sides in the reserved slot, thereby driving the fixed plate 3 to one side on both sides. The movement of the fixed plate 3 drives the telescopic rod 2 to retract inward. The telescopic rod 2 is generally tilted downward slightly and is hollow inside, thereby buffering the counter, thereby achieving the effect of increasing the service life of the device and avoiding the situation that the internal components of the counter are easily damaged due to collision when the counter is placed, affecting normal use and reducing the service life of the device. The connecting line 8 connects and fixes the dustproof frame 9. Since a strip slot is provided at the bottom of the dustproof frame 9, the operator can put the dustproof frame 9 on the surface of the sampler from the front of the sampler. The connector 10 supports and fixes the cover plate 11, and can drive the upper and lower cover plates 11 to flip, effectively preventing dust from forming on the surface of the sampler, thereby achieving the effect of improving the sampling efficiency of the sampler, and avoiding the accumulation of dust on the surface of the device after being placed for a long time when not in use, which affects the subsequent normal use of the sampler and thus reduces the sampling efficiency of the sampler. The fixing ring 13 is made of rubber material. When the operator inserts the connecting ring 15 into the arc-shaped slide groove 14, the particle sampler 7 can be driven to rotate to sample dust particles in all directions. The setting of the handle 16 facilitates the picking up and placing of the particle counter 12. The anti-slip pad 17 is anti-slip, and through the connection with the handle 16, the picking device is not easy to slip. The display screen 19 can display the sampling data intuitively.
