As shown in fig. 1 to 3, a cyclone ejector 100 includes a fixed casing 1, a rotary inner tube 2, and a rotary nozzle 3.

The fixed casing 1 comprises a connecting pipe 11, a casing 12, a first bearing 13, a second bearing 14, a dividing pipe 15, a stopper 16 and a guide pipe 17. The connecting tube 11 extends along an axis X and has a gas conveying space S and a conduit connecting portion 111 disposed in the gas conveying space S, and the conduit connecting portion 111 further has a plurality of through holes 1111 (only one is labeled in the figure) communicating with the gas conveying space S. The sleeve 12 is connected to the connecting tube 11 and has an inner stop flange 121.

The first bearing 13 and the second bearing 14 are disposed in the sleeve 12 at an interval, and the first bearing 13 is abutted against the inner stop flange 121. The separating tube 15 is disposed in the sleeve 12 and between the first bearing 13 and the second bearing 14, so that the first bearing 13 and the second bearing 14 are disposed in the sleeve 12 at intervals.

The stopper 16 is disposed in the sleeve 12 and abuts against the second bearing 14. The stopper 16 abuts against the other side of the second bearing 14 relative to the separation tube 15.

The duct 17 is fixed to the duct connection part 111, and extends into the casing 12 and extends out of the casing 12 when the connection pipe 11 is connected to the casing 12.

The two ends of the rotating inner tube 2 are respectively arranged in the first bearing 13 and the second bearing 14 in a penetrating way, so that the rotating inner tube 2 can be rotatably arranged in the fixed sleeve 1 by taking the axis X as the center; wherein, the rotating inner tube 2 is opened with a gas transmission channel 21, and the guide tube 17 passes through the gas transmission channel 21.

As described above, the outer peripheral surface of the rotating inner tube 2 further has the first cutting surface 22 and the second cutting surface 23, the first cutting surface 22 and the second cutting surface 23 respectively extend along the extending direction of the axis X, and the area of the first cutting surface 22 is larger than that of the second cutting surface 23, so that when the rotating inner tube 2 rotates, the inertia moment is unbalanced due to the difference between the areas of the first cutting surface 22 and the second cutting surface 23, and the rotating speed of the rotating inner tube 2 is inhibited.

As mentioned above, in the present embodiment, the first cutting surface 22 and the second cutting surface 23 are located on opposite sides of the outer peripheral surface of the rotating inner tube 2 with the axis X as the center, and the second cutting surface 23 is further adjacent to one of the two ends of the rotating inner tube 2, so that the gravity center distribution of the rotating inner tube 2 is not uniform, and the effect of suppressing the rotating speed can be further enhanced. In addition, in the present embodiment, the first cutting surface 22 and the second cutting surface 23 actually affect the cutting amount of the outer peripheral surface of the rotating inner tube 2, and the cutting amount is affected by the cutting area and the cutting depth, but in the present embodiment, the cutting depths of the first cutting surface 22 and the second cutting surface 23 are similar, but the cutting areas are significantly different, and the positions are arranged oppositely, so that the center of gravity of the rotating inner tube 2 can be reliably deviated from the axis X.

The rotary nozzle 3 includes a nozzle housing 31 and a flow guide plug 32. The nozzle casing 31 is connected to the inner rotating pipe 2 and has a receiving space 311, and the receiving space 311 is communicated with the gas delivery channel 21 when the nozzle casing 31 is connected to the inner rotating pipe 2; the nozzle casing 31 further has four choke pieces 312 (only one is labeled in the figure) for increasing the rotational resistance of the spin head 3 to suppress the rotational speed of the spin head 3 when the spin head 3 rotates.

The flow guiding plug 32 is disposed in the accommodating space 311, and has a spiral actuating guiding groove 321, a spiral flow guiding groove 322, a central through hole 323, and an inclined through hole 324.

The spiral actuating guide slot 321 forms a spiral pneumatic flow channel (not shown in the drawings, and is equivalent to the spiral actuating guide slot 321) with the inner wall of the nozzle casing 31 after the diversion plug 32 is disposed in the accommodating space 311, and the spiral pneumatic flow channel is further communicated with the accommodating space 311 because the diversion plug 32 occupies only a part of the space in the accommodating space 311, so as to be communicated with the gas conveying channel 21 through the accommodating space 311.

The spiral drainage channel 322 is symmetrically disposed with respect to the spiral actuation channel 321 by taking the axis X as a center, that is, the spiral actuation channel 321 and the spiral drainage channel 322 are symmetrically spirally extended by taking the axis X as a center, respectively; the spiral drainage channel 322 further forms a spiral drainage channel (not shown, equivalent to the spiral drainage channel 322) with the inner wall of the nozzle shell 31, and the spiral drainage channel 322 is also communicated with the accommodating space 311 and the gas conveying channel 21 through the accommodating space 311.

The central through hole 323 extends along the axis X and communicates with the accommodating space 311, and communicates with the gas transmission channel 21 through the accommodating space 311, and the draft tube 17 further extends through the central through hole 323. The inclined through hole 324 communicates with the spiral drainage channel 322 and extends obliquely outward toward the axis X.

With reference to fig. 4 to 6, fig. 4 is a schematic exploded view of a cyclone spraying device according to a second preferred embodiment of the present invention; FIG. 5 is a perspective view of a cyclonic spray apparatus according to a second preferred embodiment of the present invention; fig. 6 is a schematic cross-sectional view of a cyclone spraying device according to a second preferred embodiment of the present invention.

As shown in fig. 1 to 6, the cyclone injector 100 may further form a cyclone injection device 1000 with an air gun 200 and a set of connection type brush head 300, the air gun 200 includes an air gun body 201 and a transfer structure 202, the air gun body 201 is further practically connected to a high pressure gas supply source (not shown) for a user to manually control the output of a high pressure gas (not shown) provided by the high pressure gas supply source.

As mentioned above, the air gun body 201 further has a barrel 2011, and the adapter 202 is connected to the barrel 2011 and is used to connect the connection tube 11 of the fixing sleeve 1.

In addition, the assembled brush head 300 includes a brush head housing 301 and a bristle assembly 302. The brush head casing 301 is detachably sleeved on the sleeve 12 of the fixed sleeve 1, so that the rotary spray head extends into the brush head casing 301. The brush component 302 is fixed to the brush head casing 301 and has a plurality of brush hairs (not shown) for a user to brush the object to be cleaned.

In practical applications, when the high-pressure gas output from the gas gun 200 is introduced into the fixed sleeve 1 and passes through the through hole 1111, the gas transmission channel 21 and the accommodating space 311, the high-pressure gas flows out from the spiral pneumatic channel and the spiral drainage channel, so as to drive the rotary nozzle 3 and the rotary inner tube 2 to rotate around the axis X, and the high-pressure gas entering the spiral drainage channel is obliquely ejected from the inclined through hole 324 relative to the axis X, so that the high-pressure gas is rotationally ejected when the rotary nozzle 3 rotates.

As mentioned above, since the rotating inner tube 2 has the first cutting surface 22 and the second cutting surface 23 which are asymmetrically designed, even if the rotating inner tube 2 is driven by the high-pressure gas to rotate, the rotating inner tube 2 is effectively prevented from rotating too high due to the asymmetric design of the rotating inner tube 2.

The adapter tube 401 is used to connect the air gun 200 and the cyclone injector 100, and the cyclone injector 100 is connected to the air gun 200 through the adapter tube 401. The liquid storage container 402 is connected to the adapter tube 401 for storing liquid. The liquid delivery pipe 403 is disposed in the adapting pipe 401, and one end of the liquid delivery pipe 403 extends to the liquid storage container 402, and the other end of the liquid delivery pipe 403 passes through the flow guide pipe 17 along the axis X and extends into the rotary nozzle 3 of the cyclonic ejector 100, so that when the high-pressure gas provided by the air gun 200 is sprayed from the flow guide pipe 17, the liquid in the liquid storage container 402 is sprayed from the rotary nozzle 3 via the flow guide pipe 17 due to the venturi effect, and at this time, since the inclined through hole 324 extends from the spiral flow guide channel toward the axis X, the high-pressure gas flowing to the spiral flow guide channel is sprayed from the inclined through hole 324 toward the axis X, thereby changing the spraying direction of the liquid sprayed from the flow guide pipe 17, and in cooperation with the rotation of the rotary nozzle 3, the liquid is sprayed in a rotary manner.

With reference to fig. 10 to 12, fig. 10 is a schematic exploded perspective view of a cyclone spraying device according to a fourth preferred embodiment of the present invention; FIG. 11 is a perspective view of a cyclonic spray apparatus according to a fourth preferred embodiment of the present invention; fig. 12 is a schematic cross-sectional view of a cyclone spraying device according to a fourth preferred embodiment of the present invention.

As mentioned above, the dust collection assembly 500 includes a negative pressure source connection pipe 501 and a gas collection cover 502. The negative pressure source connecting pipe 501 is used to connect and communicate with a negative pressure source (not shown). The gas-collecting hood 502 is assembled to the negative pressure source connecting pipe 501, and is detachably sleeved on the fixed sleeve 1, and a gas-collecting port 5021 communicated with the negative pressure source connecting pipe 501 is formed, and the gas-collecting port 5021 is closer to the rotary nozzle 3.

In practical applications, when dust at the place to be cleaned falls down due to the impact of the gas or liquid ejected from the cyclone injector 100, the user can suck the dust away through the gas collecting hood 502 by the negative pressure generated by the negative pressure source.

In summary, compared with the rotary spraying device in the prior art, the rotating speed of the rotary nozzle is easily too high, so that the sprayed gas, liquid or fixed range is excessively dispersed; the utility model discloses borrow by and have asymmetric first cutting face and second cutting face at the outer peripheral face of inner rotary pipe, can cause the focus to deviate in the axis when inner rotary pipe is rotatory, and then make inner rotary pipe's rotational speed receive the suppression, the effectual rotational speed of avoiding rotatory nozzle is too high.
