TECHNICAL FIELD

[0001] The utility model relates to the field of dust detector, concretely is a multifunctional dust detector. BACKGROUND

[0002] Dust detector is also called dust measuring instrument or dust testing instrument, which is mainly used for detecting dust concentration in ambient air. Dust detectors are divided into laser dust detectors, online continuous monitoring dust detectors, portable dust detectors, etc. Dust detectors are widely used in disease prevention and control centers, mines, metallurgy, power plants, chemical manufacturing, health supervision, environmental protection, and environmental online monitoring.

[0003] During the detection process, the air flow in the detection area needs to be relatively stable to accurately measure the dust concentration. If the detector cannot actively extract air samples, the air flow in the detection area will be disturbed by external factors such as temperature, humidity, and wind speed, affecting the accuracy of the detection results. UTILITY MODEL CONTENT

[0004] To overcome the shortcomings of the prior art, if the detector cannot actively extract air samples, the air flow in the detection area will be disturbed by external factors such as temperature, humidity, and wind speed, affecting the accuracy of the detection results. The utility model provides a multifunctional dust detector.

[0005] The utility model solves the technical problems by adopting the following technical scheme: a multifunctional dust detector includes an instrument body, a connecting end is fixedly connected to the surface of the instrument body, a detection end is fixedly connected to one end of the connecting end, and a guide mechanism is movably sleeved on the surface of the detection end.

[0007] As a preferred, the filter assembly includes a filter plate, the surface of the filter plate is fixedly connected to the inner wall of the detection cylinder, an activated carbon plate is fixedly connected to one side of the filter plate, and the surface of the activated carbon plate is fixedly connected to one side of the filter plate.

[0008] As a preferred, a connecting shaft is rotatably connected to one side of the filter plate, a brush plate is fixedly connected to the surface of the connecting shaft, and the surface of the brush plate is attached to the surface of the filter plate.

[0009] Preferably, a motor is fixedly mounted on the surface of the detection cylinder, a transmission wheel is fixedly connected to the output end of the motor, and a transmission belt is drivingly connected to the surface of the transmission wheel and the surface of the connecting shaft.

[0010] Preferably, the inner wall of the detection cylinder is provided with a slot, and a dust collection box is fixedly inserted into the inner wall of the slot.

[0011] Preferably, the inner cavity of the connecting end is slidably connected to an elastic positioning block, and the surface of the connecting cylinder is provided with a positioning groove, and the surface of the elastic positioning block is slidably inserted into the inner wall of the positioning groove.

[0012] Preferably, a support plate is fixedly connected to the surface of the connecting end, and one side of the support plate is attached to one end of the connecting cylinder.

[0013] The advantages of this utility model are:

[0014] This invention uses a guiding mechanism to connect the instrument body to the connecting cylinder on the surface of the detection cylinder via a connecting end. Simultaneously, the detection end is vertically positioned within the inner cavity of the detection cylinder. A blower generates negative pressure on one side of the detection cylinder, drawing in air containing dust. A guide hood further enhances the efficiency of air entering the detection cylinder.

It solves the problem that if the detector cannot easily implement air extraction (i.e., cannot actively extract air samples), the airflow within the detection area will be affected by external factors such as temperature, humidity, and wind speed, thus affecting the accuracy of the detection results.
