When in use, the negative pressure blower (not shown in the figure) arranged at the air inlet (not shown in the figure) of the air knife mechanism 1 starts to work, and the external wind moves along the first direction A1 and enters the air hole tube 13. The wind in the air hole tube 13 will then run out from its own circular hole (not marked in the figure) and enter the high-pressure chamber (not shown in the figure) on the lower part of the air knife mechanism 1. The general movement process of the wind can be referred to the attached Figure 4 ; and external debris or dust will be brought into the air knife mechanism 1, and these debris or dust will generally adhere to the inner wall of the pore tube 13; on the basis of removing the sealing piece on the exhaust pipe 11 (not shown in the figure), the first transmission pipe 2 is connected to the exhaust pipe 11 of the air knife mechanism 1, and the negative pressure mechanism 3 is started, which can continuously form a reverse suction force toward the exhaust pipe 11, and the wind formed by the reverse suction will move along the second direction B1. At this time, the debris or dust on the pore tube 13 is disturbed and gradually moves toward the exhaust pipe 11, that is, moves along the second direction B1; then, these debris or dust can pass through the first transmission pipe 2, the negative pressure mechanism 3, the second transmission pipe 4, and then be discharged from the discharge end of the second transmission pipe 4 (not marked in the figure), thereby achieving the purpose of cleaning the debris or dust in the pore tube 13.

[0044] The specific structure of the air knife cleaning device is as follows: it includes a first transmission pipe 2, the feed end of which (not labeled in the figure) is connected to the exhaust pipe 11 of the air knife mechanism 1; the discharge end of which (not labeled in the figure) is directly or indirectly connected to one end of a negative pressure mechanism 3; the other end of which is connected to the feed end of a second transmission pipe 4 (not labeled in the figure), the discharge end of which is remote from the air knife mechanism 1. Compared with the prior art, the present invention omits the step of disassembling the air knife mechanism 1, thereby improving work efficiency.

[0045] In order to collect the debris or dust discharged from the air knife mechanism 1, the air knife cleaning device is also provided with a collection container 5. In a specific application scenario, as shown in the attached Figure 1 As shown, the inner wall surface of the left end of the first transmission pipe 2 is connected to the outer wall surface of the exhaust pipe 11; the left end of the first transmission pipe 2 can generally be mounted on the exhaust pipe 11, and this design can enhance the effect of reverse suction of debris or dust; the right end of the first transmission pipe 2 is connected to the working end of the negative pressure mechanism 3 (not marked in the figure), and this design can transmit the suction force through the first transmission pipe 2 into the air knife mechanism 1, thereby achieving the purpose of leading out the debris or dust inside the air knife mechanism 1; the air outlet end (not marked in the figure) of the negative pressure mechanism 3 is connected to the left end of the second transmission pipe 4, and the discharge end of the second transmission pipe 4 is connected to the left side of the collection container 5. The debris or dust discharged from the discharge end of the second transmission pipe 4 is uniformly collected by the collection container 5, thereby reducing the difficulty of handling the debris or dust. In addition, the negative pressure mechanism 3 mainly includes an air negative compressor, which can generate the negative pressure air required by the negative pressure mechanism 3.

[0046] Example 2

[0047] As attached Figure 2 As shown, this embodiment discloses an air knife cleaning device for extending the service life of the aforementioned embodiment 1. In addition to the components in the aforementioned embodiment 1, it also includes: an auxiliary collection mechanism 6 and a third transmission pipe 7. When in use, the debris or dust discharged from the air knife mechanism 1 can flow into the auxiliary collection mechanism 6 through the first transmission pipe 2; wherein, larger debris or dust will be retained in the auxiliary collection mechanism 6, and the remaining debris or dust will flow into the collection container 5 through the third transmission pipe 7, the negative pressure mechanism 3, and the second transmission pipe 4, thereby reducing the possibility of the components in the negative pressure mechanism 3 being hit by larger debris or dust. This can extend the service life of the negative pressure mechanism 3, and thus to a certain extent, can also extend the service life of the aforementioned embodiment 1.

[0048] In a specific application scenario, an auxiliary collection mechanism 6 is provided between the first transmission pipe 2 and the negative pressure mechanism 3. Figure 3As shown, the auxiliary collecting mechanism 6 comprises a shell 61, a cavity 62 is formed in the shell 61, a top wall of the cavity 62 is provided with a stopper 63, and a through hole (not marked in the figure) is formed in one side of the shell 61 and communicates with the cavity 62; the through hole divides the cavity 62 into an upper portion (not marked in the figure) and a lower portion (not marked in the figure), the through hole and the stopper 63 are located in the upper portion of the cavity 62, and the lower portion of the cavity 62 is used for collecting the debris or dust remaining in the cavity 62; the outer wall surface of the part of the first conveying pipe 2 on the right side is connected with the inner wall surface of the left side of the through hole, and the outer wall surface of the part of the third conveying pipe 7 on the left side is connected with the inner wall surface of the right side of the through hole; the right end of the third conveying pipe 7 is connected with the working end of the negative pressure mechanism 3. In use, the larger debris or dust flowing out of the first conveying pipe 2 is resisted by the stopper 63; then, the larger debris or dust remains in the lower portion of the cavity 62, and the remaining debris or dust is collected into the collecting container 5 through the third conveying pipe 7, the negative pressure mechanism 3 and the second conveying pipe 4; however, the air knife cleaning device needs to be closed every certain period of time, and the auxiliary collecting mechanism 6 is removed; then, the debris or dust in the auxiliary collecting mechanism 6 is removed by using a corresponding instrument; otherwise, the air knife cleaning device cannot continue to suck out the debris or dust in the air knife mechanism 1, so that the purpose of cleaning the air knife mechanism 1 cannot be achieved.

[0049] In order to improve the convenience of the device, the auxiliary collecting mechanism 6 is provided with a drawer 64. Part of the structure of the drawer 64 is arranged in the lower portion of the cavity 62, and the debris or dust remaining in the cavity 62 falls into the drawer 64. The user can understand the drawer 64 as a drawer; the air knife cleaning device needs the user to resist the left side of the drawer 64 with one hand and resist the right side of the drawer 64 with the other hand every certain period of time; then, the two hands are forced towards the body at the same time, and the drawer 64 can be pulled out; then, the debris or dust in the drawer 64 is poured out; then, the drawer 64 is reloaded into the auxiliary collecting mechanism 6, which can avoid the step of repeatedly disassembling the auxiliary collecting mechanism 6, thereby improving the convenience of the device and further improving the working efficiency on the basis of the foregoing structure.

[0050] Further, the front surface of the drawer 64 is provided with a handle 65. When the user needs to clean the debris or dust in the drawer 64, only one hand holds the handle 65, and the drawer 64 can be pulled out, which can improve the user's experience.
