In part 12; the suede-absorbing surface of the whole device is increased, and the suede-absorbing effect of the whole device is improved.

As Embodiment 3 of the present invention, based on Embodiment 1 or Embodiment 2, with reference to accompanying drawing 6, the end of the first conduit 4 or the second conduit 5 close to the collection part 12 is provided with a conduit outlet for cleaning Part 4012, the air outlet cleaning part 4012 of the duct is a channel with reduced pipe diameter relative to the pipes adjacent to its two ends, so as to form a local Venturi-like structure. The Venturi tube is a pipe that shrinks first and then gradually expands. Venturi effect will be generated when passing through the Venturi tube. Flow cross-section is inversely proportional. According to Bernoulli's law, the increase of flow rate is accompanied by the decrease of fluid pressure, which is the common Venturi phenomenon. In layman's terms, this effect means that a low pressure will be generated near a fluid flowing at a high speed, resulting in adsorption. In the third embodiment, the narrowed flow section of the restricted flow refers to the flow section passing through the air outlet cleaning part 4012 of the duct, and the air outlet cleaning part 4012 of the duct is connected to the cover plate 11 through the connection port 4013 connected.

Preferably, when the air outlet 1201 of the collecting part is not completely blocked, and the air outlet 4011 of the duct is basically completely blocked, a relatively low-pressure area will be formed in the air outlet cleaning part 4012 of the duct due to the change of flow velocity, The air pressure of the outside air and the air pressure of the gas in the duct air outlet cleaning part 4012 form a pressure difference, and the pressure difference makes the outside air have the power to flow into the duct air outlet cleaning part 4012, and the power makes the outside air pass through the duct air outlet cleaning part 4012. The air outlet hole of the duct air outlet 4011 pushes the collected objects attached to the inner wall of the duct air outlet 4011 inwardly, so that at least part of the collected objects attached to the inner wall of the duct air outlet 4011 can be separated from the The air outlet 4011 of the duct enters into the material collection part 12 along with the flow of the air duct in the duct; and when the air outlet 4011 of the duct reaches a certain degree of unblocking, the air outlet 4011 of the duct will discharge air outwards, blocking When the low-pressure area formed disappears, the Venturi effect also disappears correspondingly, until the collected matter basically completely blocks the air outlet 4011 of the duct again, the Venturi effect will appear again. To ensure that the air outlet 4011 of the duct will not be completely blocked before the air outlet 1201 of the collection part, so that the collected objects can be better collected into the collection part 12 . When the air outlet 1201 of the collecting part inside the collecting part 12 is completely blocked, a relatively large and stable air duct cannot be formed. At this time, if the air outlet 4011 of the duct is also blocked, the Venturi effect cannot be passed. To eliminate the attachment on the inner wall of the air outlet 4011 of the duct, the air outlet 4011 of the duct needs to be cleaned by the cleaning device 8 .

As a further preference, based on the first embodiment or the second embodiment or the third embodiment, the cover plate 11 is connected with a slider device 10 for controlling the sliding of the cover plate 11 up and down, and the slider device 10 is connected to the slider mounting bracket 9, the slider installation frame 9 is connected to the collection box device 7. Furthermore, a door opening sensor is provided on the refueling port of the collection box device 7, and when the door opening sensor detects that the refueling port is open, it can feed back a signal to the slider device 10 to control the slider device 10 drives the cover plate 11 to leave the opening of the collection part 12, and then the collection part 12 can be replaced; whether the cover plate 11 is installed on the collection part 12 is controlled by the door opening sensor and the slider device 10 In addition, the replacement efficiency can be improved, no manual disassembly is required, the replacement is convenient, and better installation accuracy can be guaranteed. The switch induction, signal feedback, and motion control of the slider device 10 of the door opening sensor are all prior art of common knowledge, and those skilled in the art can fully understand the content of the present invention, so they will not be described in detail here. Also not displayed.

The specific usage is as follows:

When the material enters the velvet device body 1 from the feed port, the destaticizing device 3 will perform an overall destaticizing treatment on the material. As the material further enters the velvet device body 1, the beating device 2 will beat the material, and at the same time, the fan assembly 6 will absorb and collect the material. The collected objects such as down or cotton wool sucked by the fan assembly 6 will enter the collecting part 12 through the first conduit 4 or the second conduit 5 . When the air outlet 1201 of the collecting part of the collecting part 12 and the air outlet 4011 of the duct are blocked, the wind blown into the collecting part 12 by the fan assembly 6 cannot be discharged, so it will flow in the collecting part 12. A high-pressure zone is formed in the material part 12 to reduce the air volume in the first duct 4 and the second duct 5. When the air volume sensor detects that the air volume has attenuated to a certain value, a signal will be fed back to control the cleaning. The annular scraper 802 of the device 8 moves, and then pushes the collected materials such as down or cotton wool attached to the inner wall of the duct air outlet 4011 into the collection part 12, so that the duct air outlet 4011 is unblocked, and the fan assembly 6. The material can continue to be collected by absorbing velvet. When the collection part 12 is full, the collection part 12 can be replaced, or after the collected objects such as down or cotton wool collected in the collection part 12 are processed, the collection part 12 for reuse.
