The working principle of the range adjusting mechanism is as follows:
when the second valve 371 is in an open state and the liquid passing hole 321 is communicated with the through hole 311 (in the process of rotating the fluid driving rotary plate 32, the liquid passing hole 321 and the through hole 311 can be intermittently communicated), the liquid inlet pipe 2, the first connecting pipe 21, the liquid passing hole 321, the through hole 311, the first liquid inlet cavity 11, the bypass pipe 37, the second liquid inlet cavity 12, the cyclone groove 161, the reducing cavity 13 and the liquid outlet hole 14 are sequentially communicated to form an intermittent liquid outlet path; when the fluid flows along the intermittent liquid outlet path, the fluid can act on the lower side of the left end of the shifting plate 33 to enable the shifting plate 33 to rotate clockwise (clockwise direction shown in fig. 1), the shifting plate 33 rotating clockwise can push the transverse plate 341 and the guide rod 34 downwards so as to enable the conical head 35 to move downwards, and further the liquid outlet gap 351 between the liquid outlet hole 14 and the conical head 35 is reduced, and as the gap between the liquid outlet hole 14 and the conical head 35 is reduced, the fluid pressure is increased, and the spraying range is increased; along with the continuous rotation of the rotating plate 32, the connection between the liquid passing hole 321 and the through hole 311 is blocked, the fluid in the first liquid inlet cavity 11 is stopped to flow, at this time, the transverse plate 341 drives the guide rod 34 and the conical head 35 to move upwards under the upward reset force of the reset component, so that the liquid outlet gap 351 between the liquid outlet hole 14 and the conical head 35 is increased, along with the increase of the liquid outlet gap 351, the fluid pressure is reduced, the spraying range is reduced, and thus, the automatic adjustment of the spraying range can be realized through the up-and-down reciprocating movement of the guide rod 34 and the conical head 35.
When the first valve 211 is in an open state and the second valve 371 is in a closed state, the liquid inlet pipe 2, the second connecting pipe 22, the second liquid inlet cavity 12, the cyclone groove 161, the reducing cavity 13 and the liquid outlet hole 14 are sequentially communicated to form a continuous liquid outlet path, and the spraying range is not adjusted because the fluid in the first liquid inlet cavity 11 does not flow, at this time, the gap between the liquid outlet hole 14 and the conical head 35 is the largest, and the atomizing nozzle can be in a state of continuous spraying and the spraying range is the smallest.
When the first valve 211 and the second valve 371 are both in the open state, the fluid in the liquid inlet pipe 2 flows through the continuous liquid outlet path and the intermittent liquid outlet path, at this time, the liquid outlet gap 351 between the liquid outlet hole 14 and the conical head 35 is automatically adjusted, and the atomizer can be in a state of continuous spraying and automatic adjustment of the spraying range for a long time.
The atomizer further comprises a pressure storage tube 41, a movable sleeve 42, a sealing plate 43 and a lifting rod 44.
One end of the pressure storage tube 41 is connected with the liquid inlet tube 2, and the other end is connected with the upper end of the liquid outlet tube 1; a check valve is arranged in the pressure storage pipe 41; referring to fig. 3, the check valve includes a liquid inlet 451, a valve seat 452, a valve element 453, and a compression spring 454; the liquid inlet 451 is located in the pressure storage tube 41, the valve seat 452 has a liquid outlet 455 and is fixed in the pressure storage tube 41, the valve element 453 is used for blocking the pressure storage tube 41, the valve element 453 is slidably matched between the liquid inlet 451 and the valve seat 452, a first gap 456 for fluid to flow is formed between the valve element 453 and the pressure storage tube 41, and the pressure spring 454 is used for enabling the valve element 453 to block the liquid inlet 451.
The movable sleeve 42 is provided with an axial hole 421 along the axial direction thereof, the upper end of the movable sleeve 42 is longitudinally and slidably matched with the pressure storage tube 41, the lower end of the movable sleeve is movably arranged in the first liquid inlet cavity 11 and is fixedly provided with a connecting rod 422, the lower end of the connecting rod 422 is slidably and rotatably connected with the upper side of the right end of the shifting plate 33, specifically, the upper side of the right end of the shifting plate 33 is slidably connected with a sliding block (not marked in the figure), and the lower end of the connecting rod 422 is hinged with the sliding block.
A sealing plate 43 is fixed to the upper end of the lifting rod 44, and the sealing plate 43 is used for sealing the upper end of the axial hole 421.
The lifting rod 44 penetrates through the axial hole 421 and a second gap 441 through which fluid can flow is reserved between the lifting rod 44 and the inner wall of the axial hole 421, the lower end of the lifting rod 44 is connected with a guide block 442 in a sliding manner, and the guide block 442 is fixed on the side wall of the first liquid inlet cavity 11; a stopper 443 is fixed to the lower portion of the lifting rod 44 outside the axial hole 421, and the stopper 443 is located between the movable sleeve 42 and the guide block 442.
The working principle of the pressure storage tube 41, the movable sleeve 42, the sealing plate 43 and the lifting rod 44 is as follows:
the first valve 211 and the second valve 371 are closed first, and the opening of the valve (not shown in the drawing) on the feed pipe 2 is gradually increased, so that the pressure of the fluid in the feed pipe 2 is gradually increased, and the valve core 453 is pushed to the right, and then the fluid acts on the top of the sealing plate 43 and the movable sleeve 42 through the drain port 455, so that the sealing plate 43, the lifting rod 44, the movable sleeve 42 and the connecting rod 422 move downward by a predetermined distance, the connecting rod 422 which moves downward rotates the rotating plate 32 clockwise (clockwise direction shown in fig. 1) around the rotating shaft, so that the transverse plate 341 and the guide rod 34 are pushed downward, so that the conical head 35 moves downward, and thus the liquid outlet gap 351 between the liquid outlet hole 14 and the conical head 35 is reduced, and the pressure in the pressure storage pipe 41 is kept unchanged due to the existence of the check valve, and thus the liquid outlet gap 351 is kept unchanged, and then the spraying range is kept unchanged, and subsequently, the first valve 211 is opened and the second valve 371 is closed, and the fluid in the feed pipe 2 flows along the continuous liquid outlet path and is sprayed from the liquid outlet gap 351 kept unchanged, so that the spraying range is automatically sprayed, that the spraying range is automatically, that the spraying range is adjusted, and the spraying range is not continuously, and the user is required to be kept in the spraying range.
In the above-mentioned process of making the atomizer not in the state of automatically adjusting the spraying range, in order to avoid the separation of the movable sleeve 42 from the sealing plate 43 in the process of moving down due to the blocking of the guide block 442 to the stop block 443, the valve on the liquid inlet pipe 2 may be closed before the stop block 443 contacts with the guide block 442. In order to facilitate observation of the relative positions of the stopper 443 and the guide block 442, the accumulator tube 41 may be provided in a transparent state, and a scale indicating the moving distance of the sealing plate 43 may be provided outside the accumulator tube 41 (the moving distance of the sealing plate 43 can reflect the change in the distance between the guide block 442 and the stopper 443).
When the function of automatically adjusting the spraying range needs to be restored, only the second valve 371 and the valve on the liquid inlet pipe 2 are required to be opened, so that the fluid in the liquid inlet pipe 2 enters the intermittent liquid outlet path, the shifting plate 33 can rotate clockwise after entering the intermittent liquid outlet path, the shifting plate 33 rotating clockwise drives the movable sleeve 42 to move downwards through the connecting rod 422, the lifting rod 44 separates the sealing plate 43 from the top of the movable sleeve 42 under the blocking of the limiting block 443 by the guide block 442, and the fluid with higher pressure in the pressure storage pipe 41 can enter the first liquid inlet cavity 11 through the axial hole 421 so as to balance the pressure in the pressure storage pipe 41 and the first liquid inlet cavity 11, so that the upward movement reset of the guide rod 34 and the conical head 35 is prevented, and the upward and downward reciprocating movement of the guide rod 34 and the conical head 35 is conveniently realized.
In a second aspect, this embodiment provides a method for using the above-mentioned atomizer, including the following steps:
