[0033] refer to Figures 1-8As shown, an atomizing nozzle 100 is proposed in an embodiment of the present invention, including a nozzle 110, a nozzle holder 120 and an extrusion drive member 133. The nozzle 110 is provided with an atomizing outlet 111, and the nozzle holder 120 is detachably connected to the nozzle 110 and cooperates with the nozzle 110 to form a accommodating chamber, which is connected to the outside world through the atomizing outlet 111. At the same time, the nozzle 110 or the nozzle holder 120 is further provided with an air inlet 123 connected to the accommodating chamber, and the accommodating chamber is used to place a liquid storage bottle 400, and the air inlet 123 is used to connect the air supply member 210. The liquid storage bottle 400 is provided with a liquid storage chamber 412 for storing liquid and a liquid outlet 411 connecting the liquid storage chamber 412 and the outside world. The effective The volume is greater than that of the liquid storage bottle 400, so as to form an air flow channel connecting the air inlet 123 and the liquid outlet 411 between the liquid storage bottle 400 and the cavity wall of the accommodating cavity. The liquid outlet 411 is not higher than the atomizing port 111, so that the air flow flows to the liquid squeezed out from the liquid outlet 411, thereby dispersing the liquid into a spray form. The extrusion drive member 133 can drive the piston 420 in the liquid storage bottle 400 to move toward the liquid outlet 411 to squeeze the liquid in the liquid storage bottle 400 from the liquid outlet 411 of the liquid storage bottle 400. The liquid is squeezed out through the liquid outlet 411 and sprayed out of the atomizing port 111 in the form of a spray under the action of the air flow, or forms a spray outside the atomizing port 111 and directly acts on the human body or other working areas. It can be understood that the piston 420 can be fixed on the extrusion drive member 133 as the output end of the extrusion drive member 133, and the extrusion drive member 133 moves in the liquid storage bottle 400 while the extrusion drive member 133 is working, or it can be slidably arranged inside the liquid storage bottle 400 as a component structure of the liquid storage bottle 400, and the output end of the extrusion drive member 133 abuts against the piston 420 and pushes the piston 420 to move.

[0034] The above-mentioned atomizing nozzle 100 uses the extrusion drive member 133 to squeeze the piston 420 in the liquid storage bottle 400, so that the liquid moves toward the liquid outlet 411 under the push of the piston 420. Compared with using a fluid pump to squeeze out the liquid, the amount of liquid squeezed out can be accurately controlled without being affected by the density of the liquid.

[0035] In order to prevent the liquid storage bottle 400 from moving as a whole with the extrusion driving member 133 when the extrusion driving member 133 squeezes the liquid storage bottle 400, thereby affecting the liquid extrusion effect, the liquid storage bottle 400 is detachably fixedly connected to the nozzle holder 120 using connection methods including but not limited to threaded connection, plug-in connection, etc.

[0036] In one embodiment, referring to Figure 3 and Figure 4As shown, the nozzle holder 120 is configured as a cylindrical structure with both ends open in the axial direction. The outer circumferential wall of the first end of the nozzle holder 120 is provided with an external thread, and the inner circumferential wall of the nozzle 110 is provided with an internal thread. The nozzle 110 and the nozzle holder 120 are threadedly connected by the mating external and internal threads. Furthermore, a plug-in ring 121 is provided within the second end of the nozzle holder 120. A gap exists between the plug-in ring 121 and the inner circumferential wall of the nozzle holder 120. The plug-in ring 121 allows the liquid storage bottle 400 to be plugged into the nozzle holder 120 to secure the liquid storage bottle 400 within the accommodating cavity, preventing the entire liquid storage bottle 400 from moving along with the extrusion drive 133 and affecting the extrusion effect.

[0037] Specifically, the first end face of the nozzle 110 away from the extrusion drive member 133 is set to be conical, the atomizing outlet 111 is set on the first end face of the nozzle 110, the liquid outlet 411 of the liquid storage bottle 400 placed 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 where the liquid outlet 411 is set is also set to be conical to increase the speed of the airflow when it is sprayed out of the atomizing outlet 111.

[0038] Furthermore, the inner surface of the first end face of the nozzle 110 is circumferentially spaced apart with a plurality of first limiting protrusions 112. When the liquid storage bottle 400 is inserted into the insertion ring 121, the first limiting protrusions 112 abut against the liquid storage bottle 400, further improving the stability of the liquid storage bottle 400. Simultaneously, the spaced-apart first limiting protrusions 112 also create a gap between the first end face of the nozzle 110 and the liquid storage bottle 400, thereby ensuring the patency of the airflow channel. The inner circumferential wall of the nozzle holder 120 is circumferentially spaced apart with a plurality of second limiting protrusions 122. The second limiting protrusions 122 also abut against the liquid storage bottle 400, thereby improving the stability of the liquid storage bottle 400 and creating a gap between the nozzle holder 120 and the liquid storage bottle 400, thereby ensuring the patency of the airflow channel. It is understandable that sealing gaskets 170 are provided outside the plug-in ring 121 and between the nozzle 110 and the nozzle seat 120 to ensure the sealing of the air flow channel. Of course, the sealing gasket 170 located outside the plug-in ring 121 cannot affect the air permeability of the air inlet 123.

[0039] Specifically, the end surface of the second limiting protrusion 122 facing the nozzle 110 is set as an inclined surface to play a guiding role when the liquid storage bottle 400 enters the nozzle seat 120, thereby reducing the difficulty of inserting the liquid storage bottle 400 into the nozzle seat 120.

[0040] refer to Figure 2 and Figure 3As shown, the atomizing nozzle includes an extrusion assembly 130, which includes the above-mentioned extrusion drive 133, a screw 131, and a screw sleeve 132. The extrusion drive 133 uses a reduction motor and transmits the moving power to the piston 420 through the mutually cooperating screw 131 and screw sleeve 132. The screw sleeve 132 is sleeved on the screw 131. The screw sleeve 132 can make a linear motion when the screw 131 rotates to serve as the output end of the extrusion drive to push the piston 420 to move. The reduction motor is connected to the screw 131 to drive the screw 131 to rotate. The mutual cooperation between the screw 131 and the screw sleeve 132 can convert the rotational motion of the reduction motor into linear motion, further improving the accuracy of the quantitative extrusion of the liquid from the liquid outlet 411. Specifically, in order to avoid interference between the screw 131 and the piston 420, the screw sleeve 132 is sleeved on the first end of the screw 131 and the screw 131 does not protrude from the screw sleeve 132 in the direction of movement of the screw sleeve 132.

[0041] In other embodiments, the extrusion drive member 133 may also adopt a linear drive structure such as a cylinder or an electric cylinder.

[0042] In order to determine the position of the screw sleeve 132 and thus the position of the piston 420, the atomizing nozzle 100 further includes a monitoring assembly 140 electrically connected to the extrusion drive member 133. The monitoring assembly 140 includes a first monitoring member 141, wherein the first monitoring member 141 is stationary relative to the nozzle holder 120. The first monitoring member 141 is used to monitor whether the screw sleeve 132 is in an initial position or an end position. When the screw sleeve 132 is in the initial position, the liquid storage bottle 400 can be assembled in the accommodating chamber. When the screw sleeve 132 is in the end position, the piston 420 completely abuts against the inner surface of the first end face of the bottle body 410, that is, the liquid in the liquid storage bottle 400 is completely squeezed out. It can be understood that when the screw sleeve 132 is in the initial position, the liquid storage bottle 400 that can be assembled in the accommodating chamber refers to a new liquid storage bottle 400 containing a fixed amount of liquid.

[0043] In one embodiment, the first monitoring component 141 includes a Hall switch, the screw sleeve 132 includes a magnet 180 for triggering the Hall switch, and two Hall switches are arranged at intervals along the moving direction of the piston 420. When the magnet 180 is opposite to a Hall switch that is relatively far away from the accommodating chamber between the two Hall elements, a first induction signal can be generated, and at this time the screw sleeve 132 is in the initial position; when the magnet 180 is opposite to a Hall switch that is relatively close to the accommodating chamber between the two Hall elements, a second induction signal can be generated, and at this time the screw sleeve 132 is in the end position.

[0044] In other embodiments, the first monitoring component 141 can also be a distance sensor. When the distance sensor detects that the relative distance between the screw sleeve 132 and a point on the nozzle seat 120 or the relative distance between the screw sleeve 132 and a point stationary relative to the nozzle seat 120 is within a first preset range, a first sensing signal is generated, and at this time the screw sleeve 132 is in the initial position. When the distance sensor detects that the relative distance between the screw sleeve 132 and a point on the nozzle seat 120 or the relative distance between the screw sleeve 132 and a point stationary relative to the nozzle seat 120 is within a second preset range, a second sensing signal is generated, and at this time the screw sleeve 132 is in the end position.

[0045] In one embodiment, the monitoring assembly 140 also includes a second monitoring component 142, which is arranged on the screw sleeve 132 to move with the screw sleeve 132. The second monitoring component 142 is used to monitor whether the screw sleeve 132 abuts against the piston 420. At this time, the piston 420 serves as a component structure of the liquid storage bottle 400. The liquid storage bottle 400 includes a bottle body 410 and a piston 420. The liquid outlet 411 is opened at the first end of the bottle body 410. The piston 420 is slidingly sealed and arranged in the bottle body 410. The output end of the extrusion drive component 133 can penetrate into the bottle body 410 from the second end of the bottle body 410 to abut against the piston 420.

[0046] In one embodiment, the second monitoring component 142 also includes a Hall switch, and the liquid storage bottle 400 includes a magnet 180 for triggering the second monitoring component 142. In order to improve the signal sensitivity, the Hall switch is arranged in the screw sleeve 132 and is located at the end of the screw sleeve 132 close to the piston 420. The magnet 180 is embedded in the end of the piston 420 close to the screw sleeve 132. When the Hall switch generates a third sensing signal, the screw sleeve 132 abuts against the piston 420.

[0047] Of course, in other embodiments, the second monitoring component 142 may also be a distance sensor, which will not be further described here.

[0048] In order to avoid the situation where the air supply component 210 connected to the accommodating chamber is started but no liquid is squeezed out of the liquid outlet 411, the air supply component 210 can only be started by pressing the start button of the air supply component 210 under the premise that the Hall switch serving as the second monitoring component 142 generates a third sensing signal.

[0049] In order to protect the extrusion drive member 133, in one embodiment, the atomizing nozzle 100 also includes an outer shell 150 and an inner bracket 160. The second end of the nozzle holder 120 is fixedly inserted into the outer shell 150, and the second end of the nozzle holder 120 is located outside the outer shell 150. The reduction motor is fixed in the outer shell 150 through the inner bracket 160. The output end of the extrusion drive member 133 can be inserted into the nozzle holder 120 to squeeze the liquid in the liquid storage bottle 400.

[0050] At the same time, the atomizing nozzle 100 also includes a control circuit board 190 electrically connected to the extrusion drive member 133 and the monitoring assembly 140. The control circuit board 190 and the monitoring assembly 140 are both located within the housing 150. The control circuit board 190 is used to control the opening and closing of the extrusion drive member 133 and the output direction. The start button of the air supply member 210 is also set on the control circuit board 190, that is, the control circuit board can also control the opening and closing and power of the air supply member 210. The output end of the extrusion drive member 133, namely the screw sleeve 132, can pass through the housing 150 to push the piston 420 to move. Specifically, a limiting groove is provided on the outer peripheral wall of the nozzle holder 120, and the nozzle holder 120 is embedded in the open end of the housing 150 through the limiting groove.

[0051] The present invention also provides an atomizer in an embodiment, comprising a main unit 200 and an atomizing nozzle 100 according to any of the above-described embodiments. An air supply member 210 is disposed within the main unit 200 and connected to the atomizing nozzle 100 via an air duct 300. Furthermore, the air supply member 210 is connected to the control circuit board 190 via a cable. One end of the air duct 300 is connected to the outlet of the air supply member 210, and the other end is connected to the accommodating chamber via an air inlet 123. Specifically, to prevent the air duct 300 from being exposed outside the housing 150, the air inlet 123 is provided on the second end face of the nozzle holder 120. The air supply member 210 includes a vacuum pump, which can rapidly blow air into the accommodating chamber through the air duct 300 and flow to the liquid outlet 411 through the air flow channel.

[0052] To facilitate adjustment of the angle and relative position of liquid outlet 411 to the human body or other working area, air duct 300 is constructed as a flexible tube. This allows housing 150 to move relative to main unit 200. Housing 150 is designed to be easily gripped by a human hand, for example, cylindrical. Specifically, air duct 300 is integrated with the cable connecting air supply unit 210 to control circuit board 190.

[0053] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
