[0027] Referring to FIGS. 1-8, the atomizing nozzle 100 in the embodiments of the present application includes a nozzle 110, a nozzle seat 120, and an extrusion driving member 133. The nozzle 110 is provided with an atomizing outlet 111. The nozzle seat 120 is detachably connected with the nozzle 110 and cooperates with the nozzle 110 to form a containing cavity. The containing cavity is communicated with the outside through the atomizing outlet 111. The nozzle 110 or the nozzle seat 120 is further provided with an air inlet 123 communicated with the containing cavity. The containing cavity is arranged to place a liquid storage bottle 400. The air inlet 123 is arranged to connect with a gas supply member 210. The liquid storage bottle 400 is provided with a liquid storage cavity 412 for storing liquid and a liquid outlet 411 communicated with the liquid storage cavity 412 and the outside. The effective volume of the containing cavity is greater than the volume of the liquid storage bottle 400, so as to form an airflow channel communicated with the air inlet 123 and the liquid outlet 411 between the liquid storage bottle 400 and the cavity wall of the containing cavity. The liquid outlet 411 is not higher than the atomizing outlet 111. The gas flow flows towards the liquid extruded from the liquid outlet 411, so as to disperse the liquid into a spray form. The extrusion driving member 133 can drive the piston 420 in the liquid storage bottle 400 to move towards the liquid outlet 411, so as to extrude the liquid in the liquid storage bottle 400 from the liquid outlet 411 of the liquid storage bottle 400. The liquid is extruded from the liquid outlet 411 and sprayed in a spray form under the action of the airflow, or forms a spray outside the atomizing outlet 111 and directly acts on the human body or other working areas. The piston 420 can be fixed on the extrusion driving member 133 as an output end of the extrusion driving member 133. The extrusion driving member 133 moves in the liquid storage bottle 400 while working. The piston 420 can also be arranged to slide in the liquid storage bottle 400 as a component structure of the liquid storage bottle 400. The output end of the extrusion driving member 133 abuts against the piston 420 to drive the piston 420 to move.

[0028] The atomizing nozzle 100 described above extrudes the piston 420 in the liquid storage bottle 400 by using the extrusion driving member 133, so that the liquid moves towards the liquid outlet 411 under the pushing of the piston 420. Compared with extruding the liquid by using a fluid pump, the extrusion amount of the liquid can be accurately controlled and is not affected by the density of the liquid.

[0029] In order to prevent the liquid storage bottle 400 from moving together with the extrusion driving member 133 when the extrusion driving member 133 extrudes the liquid storage bottle 400, affecting the liquid extrusion effect, the liquid storage bottle 400 can be detachably fixedly connected with the nozzle seat 120 in a threaded connection or plug-in connection manner.

[0031] In some embodiments, the first end face of the nozzle 110 away from the extrusion driving member 133 is provided as a tapered shape, and the atomizing outlet 111 is arranged on the first end face of the nozzle 110, and the liquid outlet 411 of the liquid storage bottle 400 arranged in the accommodating cavity is coaxially arranged with the atomizing outlet 111 and inserted into the atomizing outlet 111, and the end of the liquid storage bottle 400 provided with the liquid outlet 411 is also provided as a tapered shape to improve the speed of the airflow when sprayed out of the atomizing outlet 111.

[0032] In some embodiments, the inner surface of the first end face of the nozzle 110 is also circumferentially and interval ly provided with a plurality of first limiting protrusions 112, and when the liquid storage bottle 400 is plug-in matched with the plug-in ring 121, the first limiting protrusions 112 abut against the liquid storage bottle 400 to improve the stability of the liquid storage bottle 400, and at the same time, the interval ly arranged first limiting protrusions 112 can also make the first end face of the nozzle 110 and the liquid storage bottle 400 have a gap therebetween to ensure the smoothness of the airflow passage. The inner peripheral wall of the nozzle seat 120 is circumferentially and interval ly provided with a plurality of second limiting protrusions 122, and the second limiting protrusions 122 also abut against the liquid storage bottle 400 to improve the stability of the liquid storage bottle 400 while making the nozzle seat 120 and the liquid storage bottle 400 have a gap therebetween to ensure the smoothness of the airflow passage. It can be understood that the sealing gaskets 170 are arranged outside the plug-in ring 121 and between the nozzle 110 and the nozzle seat 120 to ensure the sealing of the airflow passage, and the sealing gaskets 170 located outside the plug-in ring 121 cannot affect the air permeability of the air inlet 123.

[0033] In some embodiments, the end of the second limiting protrusion 122 facing the end face of the nozzle 110 is provided as an inclined surface to play a guiding role when the liquid storage bottle 400 enters the nozzle seat 120, and to reduce the difficulty of inserting the liquid storage bottle 400 into the nozzle seat 120.

[0034] Referring to FIG. 2 and FIG. 3, the atomizing head 100 comprises an extrusion assembly 130, the extrusion assembly 130 comprises the extrusion driving member 133, a screw rod 131 and a screw sleeve 132, the extrusion driving member 133 is a reduction motor, and the screw rod 131 and the screw sleeve 132 are cooperated to transmit the moving power to the piston 420, the screw sleeve 132 is sleeved on the screw rod 131, and the screw sleeve 132 can move linearly to push the piston 420 to move as the output end of the extrusion driving member 133 when the screw rod 131 rotates, and the reduction motor is connected with the screw rod 131 to drive the screw rod 131 to rotate. The cooperation of the screw rod 131 and the screw sleeve 132 can convert the rotary motion of the reduction motor into linear motion, and the accuracy of the liquid being quantitatively extruded from the liquid outlet 411 is improved. Optionally, in order to avoid the interference between the screw rod 131 and the piston 420, the screw sleeve 132 is sleeved on the first end of the screw rod 131, and the screw rod 131 does not protrude from the screw sleeve 132 in the moving direction of the screw sleeve 132.

When the screw sleeve 132 is in the initial position, the liquid storage bottle 400 that can be assembled in the accommodating cavity refers to a new liquid storage bottle 400 containing a certain amount of liquid.

[0038] In other embodiments, the first monitoring member 141 can also be a distance sensor, which generates a first sensing signal when the distance sensor monitors that the relative distance between the screw sleeve 132 and a certain point on the nozzle seat 120 or the relative distance between the screw sleeve 132 and a certain point that is stationary relative to the nozzle seat 120 is within a first preset range, at which time the screw sleeve 132 is in the initial position, and generates a second sensing signal when the distance sensor monitors that the relative distance between the screw sleeve 132 and a certain point on the nozzle seat 120 or the relative distance between the screw sleeve 132 and a certain point that is stationary relative to the nozzle seat 120 is within a second preset range, at which time the screw sleeve 132 is in the end position.
