[0047] The pushing piece 202 comprises an outer pushing cylinder 202a fixedly arranged inside the driving ring 201a, the outer pushing cylinder 202a is hollow, and an inner pushing cylinder 202b is movably inserted into the outer pushing cylinder 202a, and a telescopic spring 202c is arranged between the inner pushing cylinder 202b and the outer pushing cylinder 202a, so that the inner pushing cylinder 202b can perform telescopic movement relative to the outer pushing cylinder 202a under the elastic force of the telescopic spring 202c.

[0048] The lifting piece 203 comprises a lifting seat 203a mounted in the interior of the atomizing cap body 101, the inner side of the lifting seat 203a is provided with a limiting groove 203b, the outer side of the lifting seat 203a is movably connected with a rotatable rotating seat 203c, the outer side surface of the lifting seat 203a is provided with a lifting groove 203d, the upper end of the lifting groove 203d is further communicated with an extrusion groove 203e, and the outer side surface of the rotating seat 203c is also provided with a pushing groove 203f.

[0049] Preferably, the support 204 is arranged in an L shape, and the vertical section of the support 204 is movably embedded in the limiting groove 203b and can slide in the limiting groove 203b, so that the lifting seat 203a can only perform axial lifting movement under the limitation and guidance of the support 204 through the sliding cooperation between the support 204 and the limiting groove 203b, and the horizontal section of the support 204 can support the lifting seat 203a under the L-shaped arrangement of the support 204, and the support 204 can support the lifting seat 203a after the lifting seat 203a completes the downward movement.

[0050] Further, the lifting groove 203d is provided with an inclined spiral along the surface of the lifting seat 203a, the inner push cylinder 202b is movably embedded in the lifting groove 203d and can slide in the lifting groove 203d, so that when the driving ring 201a rotates, the inner push cylinder 202b can generate a pushing force on the lifting seat 203a through the lifting groove 203d, and under the guidance of the inclined groove wall of the lifting groove 203d, the lifting seat 203a limited by the support 204 can be driven to move up and down, so that the position of the lifting seat 203a changes, thereby realizing the position adjustment of the landing piece 205 and the cleaning piece 206 through the lifting of the lifting seat 203a, to meet the use requirements of users in different situations.

[0051] The bottom surface of the extrusion groove 203e is inclined, when the inner push cylinder 202b slides to one end of the extrusion groove 203e along the lifting groove 203d, under the telescopic setting of the inner push cylinder 202b, with the rotation of the driving ring 201a, the inner push cylinder 202b further moves in the extrusion groove 203e, at this time the groove bottom of the extrusion groove 203e can gradually extrude the inner push cylinder 202b, so that the inner push cylinder 202b shrinks into the outer push cylinder 202a, and with the continuous rotation of the driving ring 201a, the pusher 202 can be disconnected from the lifting seat 203a, at this time the pusher 202 only exists in the push groove 203f, so that under the cooperation of the outer push cylinder 202a and the push groove 203f, with the rotation of the driving ring 201a, the relative rotation between the rotating seat 203c and the lifting seat 203a can be realized, to realize the cooperation and linkage between the landing piece 205 and the cleaning piece 206.

[0052] Meanwhile, the lifting groove 203d and the push groove 203f are coincidentally arranged, the push groove 203f is the projection of the lifting groove 203d on the rotating seat 203c, and the bottom of the push groove 203f is open, so that when the pusher 202 slides along the lifting groove 203d, the outer push cylinder 202a can move into the push groove 203f, so that when the inner push cylinder 202b retracts, only the outer push cylinder 202a in the pusher 202 cooperates with the push groove 203f, and then when the driving ring 201a further rotates, the synchronous rotation between the rotating seat 203c and the driving ring 201a can be realized by the abutting cooperation between the outer push cylinder 202a and the push groove 203f.

[0053] Further, the landing piece 205 includes a landing disc 205a fixed with the rotating seat 203c, and the surface of the landing disc 205a is sequentially fixed with an outer landing ring 205b and an inner landing ring 205c from outside to inside, and the surfaces of the outer landing ring 205b and the inner landing ring 205c are provided with pull grooves 205d.

[0054] The cleaning member 206 comprises a positioning rod 206a arranged on the lifting disc 205a, the bottom of the positioning rod 206a is integrally provided with a pulling ball 206b, the pulling ball 206b is slidingly arranged in the pulling groove 205d, and the positioning rod 206a can move synchronously with the lifting of the lifting ring while the pulling ball 206b is slidingly arranged in the pulling groove 205d. The top of the positioning rod 206a is further integrally provided with a cleaning piston 206d corresponding to the main control hole 104, and the top of the cleaning piston 206d is conical to facilitate the insertion of the cleaning piston 206d into the blocked main control hole 104.

[0055] The outer lifting ring 205b and the inner lifting ring 205c are both arranged in a corrugated manner, and the surfaces of the two are connected by a plurality of adjacent peaks and valleys in a ring array, so that when the lifting disc 205a rotates, the positioning rod 206a positioned and guided by the guide 207 can be pushed to move up and down through the height difference between the peaks and valleys and the pulling cooperation between the pulling groove 205d and the pulling ball 206b, so that the cleaning piston 206d can reciprocatingly lift in the main control hole 104, thereby achieving the purpose of cleaning and dredging the inside of the main control hole 104.

[0056] When the atomizing cap body 101 is not used, the lifting member 203 is located at the top of the atomizing cap body 101, and at this time, the cleaning member 206 penetrates into the main control hole 104 to achieve the closure of the main control hole 104. When the spray gun is working, the driving ring 201a is rotated clockwise, and under the cooperation of the inner push cylinder 202b and the lifting groove 203d, the lifting seat 203a guided by the support 204 is lowered, so that the cleaning member 206 is moved out of the main control hole 104. When the inner push cylinder 202b moves to the top of the lifting groove 203d, the lifting member 203 and the cleaning member 206 fall into place at this time, and the spray gun can perform the spraying work. When it is found that the spraying range deviates, the spraying range is split or the spraying range is difficult to adjust during the spraying process, it indicates that the control hole is blocked and needs to be cleaned. At this time, the driving ring 201a can be continuously rotated clockwise, the inner push cylinder 202b slides along the lifting groove 203d to one end of the extrusion groove 203e, and under the inclination setting at the bottom of the extrusion groove 203e, the inner push cylinder 202b is retracted into the outer push cylinder 202a to be separated from the lifting seat 203a with the rotation of the driving ring 201a. Subsequently, under the cooperation of the outer push cylinder 202a and the push groove 203f, the rotating seat 203c is synchronously rotated with the driving ring 201a, and at this time, the lifting disc 205a is synchronously rotated with the rotating seat 203c, so that the cleaning member 206 is reciprocatingly lifted and lowered in the main control hole 104 under the driving of the outer lifting ring 205b and the inner lifting ring 205c to the cleaning member 206. The cleaning member 206 achieves the dredging and cleaning of the main control hole 104. The rotation of the driving ring 201a is one cycle, and after the cleaning is completed, the driving ring 201a is rotated to the starting position before cleaning. Through the cooperation between the driving member 201, the pushing member 202, the lifting member 203, the lifting member 205 and the cleaning member 206, the switching between the opening and closing of the atomizing cap and the self-cleaning state can be realized. At the same time, under the cooperation of the lifting member 205 and the cleaning member 206, the cleaning member 206 can reciprocatingly lift and lower in the main control hole 104, which meets the cleaning demand of the user for the main control hole 104 and ensures the cleaning effect of the self-cleaning function of the atomizing cap. The cleaning difficulty of the atomizing cap is reduced, and unnecessary production cost caused by replacing the atomizing cap is avoided.
