Description

Technical Field

[0001] This utility model relates to the technical field of rotating air curtain capture devices, specifically a handheld non-contact rotating air curtain capture device. Background Technology

[0002] Current non-contact detection technologies are mainly applied in biomedical engineering, metallurgy and metalworking, the power industry, the machinery industry, and railway transportation. In fields requiring non-contact particle capture, non-contact collection methods are needed. Existing collection devices mostly use a single fan for direct collection, resulting in short operating distances and low collection efficiency. High-efficiency devices are bulky, difficult to carry, and prone to accidents, posing health risks to operators. Therefore, improvements to existing technologies are necessary. Utility Model Content

[0003] The purpose of this invention is to provide a handheld, non-contact rotating air curtain collection device that solves the problems of short operating distance, low collection efficiency, and inconvenience in carrying.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a handheld non-contact rotating air curtain collection device, comprising a suction chamber, a central suction pipe provided at the upper end of the suction chamber, a cavity cover fixedly connected to the outer side of the central suction pipe, guide vanes fixedly connected to the outer side of the central suction pipe, a pipe one fixedly installed on the outer side of the central suction pipe, a centrifugal fan installed inside the suction chamber, a blower fixedly installed on the outer side of the suction chamber, and a pipe two installed at the lower end of the suction chamber.

[0005] Preferably, there are multiple guide vanes, which are evenly distributed along the outer surface of the tail of the central suction pipe. When the airflow passes through the guide vanes, it can obtain tangential velocity and form a rotating air curtain.

[0006] Preferably, the pipe is fixedly connected to the blower, and a handle is fixedly connected to the outside of the suction chamber, which makes the device easier to hold and carry.

[0007] Preferably, the handle is parallel to the central axis of the central suction pipe, and this parallel design makes operation more convenient.

[0008] Preferably, the outer side of the cavity cover is provided with multiple evenly distributed annular air outlets, which can be used for exhaust.

[0009] Preferably, a dust collection chamber is installed at the lower end of the second pipe, and a collection port is installed on the outside of the dust collection chamber, which can store samples.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention adds a central suction pipe, guide vanes, and a blower to the suction chamber. During use, the blower sprays airflow, which drives the particles to move. At the same time, the central suction pipe draws in and collects particles within the capture area, thereby effectively increasing the collection distance and avoiding close contact between personnel and particles. The device is also compact and small in size, making it easy to carry and use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6A handheld non-contact rotating air curtain trapping device includes a suction chamber 7, a central suction pipe 1 at the upper end of the suction chamber 7, a cavity cover 2 fixedly connected to the outside of the central suction pipe 1, a guide vane 3 fixedly connected to the outside of the central suction pipe 1, a pipe 4 fixedly installed on the outside of the central suction pipe 1, a centrifugal fan 8 installed inside the suction chamber 7, a blower 9 fixedly installed on the outside of the suction chamber 7, and a pipe 10 installed at the lower end of the suction chamber 7.

[0021] Please see Figure 1-6 There are multiple guide vanes 3, which are evenly distributed along the outer surface of the tail of the central suction pipe 1. When the airflow passes through the guide vanes 3, it can obtain tangential velocity and form a rotating air curtain. The pipe 4 is fixedly connected to the blower 9. A handle 13 is fixedly connected to the outside of the suction chamber 7. The handle 13 makes the device easier to hold and carry.

[0022] Please see Figure 1-6 The handle 13 is parallel to the central axis of the central suction pipe 1. The parallel design makes operation more convenient. Multiple evenly distributed annular air outlets 5 are opened on the outside of the cavity cover 2. The annular air outlets 5 can exhaust air. A dust collection chamber 11 is installed at the lower end of the pipe 2 10. A collection port 12 is installed on the outside of the dust collection chamber 11. The dust collection chamber 11 can store samples.

[0023] The specific implementation process of this utility model is as follows: When in use, hold the handle 13 to pick up the device, and then start the blower 9. The blower 9 generates airflow that is blown into the cavity hood 2 through the pipe 1 4. The airflow is accelerated by the guide vane 3 inside the cavity hood 2 and forms a rotating air curtain. After the airflow forms a rotating air curtain, it can be sprayed out through the annular air outlet 5, which can disturb the airflow inside the sampling area. At the same time, start the centrifugal fan 8. The centrifugal fan 8 generates suction. The suction draws the particulate matter inside the sampling area into the suction chamber 7 through the central suction pipe 1. During the suction process, the airflow enters the dust collection chamber 11 through the pipe 2 10 and comes into contact with the collection port 12 inside the dust collection chamber 11 for detection.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
