[0030] Embodiment 1

[0031] Referring to Figure 1 and Figure 2 , a first embodiment of the present utility model provides a wind field adjustment device, which includes

[0032] A wind field processing unit 100, including a power component 101, a filtering component 102 provided on the power component 101 for filtering, and an adjusting component 103 provided on the power component 101; the power component includes a wind cylinder 101a having an air inlet 101a-1, and a fan 101b provided in the wind cylinder 101a; a jet unit 200 is provided at one end of the wind cylinder 101a and located at the air outlet end of the fan 101b, and a suction unit 300 is provided on the filtering component 102.

[0033] Among them, the jet unit 200 includes a necking pipe 202 provided on the wind cylinder 101a, a connecting pipe 201 provided on the necking pipe 202, and a nozzle 203 provided on the connecting pipe 201. The filtering component 102 includes a filtering pipe 102a provided on the wind cylinder 101a, a mounting frame 102b provided in the filtering pipe 102a, and a filter element 102c slidably provided on the mounting frame 102b and detachably connected. The suction unit 300 includes a connecting sleeve 303 provided on the filtering pipe 102a, a delivery pipe 302 provided on the connecting sleeve 303, and a suction hood 301 provided on the delivery pipe 302.

[0034] During use, the air in the air duct 101a is injected into the necking pipe 202 through the fan 101b, and then conveyed to the nozzle 203 through the connecting pipe 201 and sprayed out from the nozzle 203, so as to be able to blow away the residual substances and make the residual substances move towards the direction of the suction hood 301. After a negative pressure is generated in the air duct 101a, the air enters the filter pipe 102a through the suction hood 301, the conveying pipe 302, and the connecting sleeve 303, and then enters the air duct 101a after being filtered by the filter element 102c, thus completing a gas circulation. When the gas circulates, it will suck in the substances near the suction hood 301, so as to be able to carry out dust suction treatment. When the filter element 102c is blocked by substances, the filter element 102c will move according to the degree of blockage, thus driving the adjustment assembly 103 to move, and being able to control the size of the exposed air inlet 101a-1, so as to supplement the air intake without affecting the normal operation of the jet unit 200.

[0035] Embodiment 2

[0036] Refer to Figures 1 - 4 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: further, a plurality of air inlets 101a-1 are provided. The adjustment assembly 103 includes a plurality of sealing plates 103a slidably arranged on the air duct 101a and located at the air inlets 101a-1, a blocking part arranged in the air duct 101a for pushing the sealing plate 103a to move, and a pushing part arranged on the filter element 102c for pushing the sealing plate 103a to release the seal.

[0037] Among them, the blocking part includes a support frame 103c arranged in the air duct 101a, a pushing frame 103b arranged on the sealing plate 103a, and an elastic member 103d arranged on the support frame 103c for pushing the pushing frame 103b to move towards the filter element 102c. A plug hole 103b-1 is arranged on the pushing frame 103b; the pushing part includes a push rod 103e arranged in the filter element 102c and one end of which is inserted into the plug hole 103b-1 and abuts against the pushing frame 103b.

[0038] Preferably, a filter screen 101c is arranged on the air duct 101a; a plurality of filter screens 101c corresponding to the air inlets 101a-1 are arranged and located at the air inlets 101a-1; the filter screen 101c can prevent dust from entering the air duct 101a.

[0039] During use, when the filter element 102c is blocked, its air flow permeability decreases. As a result, with the power of the fan 101b remaining unchanged, it will drive the filter element 102c to move towards the fan 101b, causing the filter element 102c to drive the push rod 103e to move. The push rod 103e pushes the push frame 103b to move, and the push frame 103b drives the sealing plate 103a to move, causing the sealing plate 103a to contact and block the air inlet 101a-1, enabling air to enter the air duct 101a from the air inlet 101a-1 without affecting the normal operation of the jet unit 200. Moreover, the degree of blockage of the filter element 102c can be judged by the position of the sealing plate 103a. When the filter element 102c is unblocked, the elastic member 103d is used to push the push frame 103b to move, causing the push frame 103b to drive the sealing plate 103a to move to seal the air inlet 101a-1; the position of the sealing plate 103a can be automatically adjusted according to the degree of blockage of the filter element 102c.

[0040] The remaining structure is the same as that of Embodiment 1.

[0041] Embodiment 3

[0042] Referring to Figure 1 and Figure 4 This is the third embodiment of the present utility model. The difference between this embodiment and the second embodiment is that a connecting component 104 is provided on the air duct 101a and the filter tube 102a; the connecting component 104 includes a support foot 104a provided at the lower parts of the air duct 101a and the filter tube 102a, and a positioning rod 104b provided on the support foot 104a of the air duct 101a; a positioning hole is provided on the support foot 104a of the filter tube 102a, and the positioning rod 104b is embedded into the positioning hole. The connecting component 104 further includes two magnets 104d respectively provided on the air duct 101a and the filter tube 102a.

[0043] During use, the filter tube 102a is pushed towards the air duct 101a by aligning the positioning hole with the positioning rod 104b, causing the positioning rod 104b to be inserted into the positioning hole, thereby enabling the positioning of the support foot 104a and avoiding the problems of rotation and shaking during use; when the filter tube 102a approaches the air duct 101a, the filter tube 102a is connected to the air duct 101a through the magnet 104d, and a sealing gasket is provided between the air duct 101a and the filter tube 102a to improve its sealing effect.

[0044] The remaining structure is the same as that of Embodiment 2.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
