Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0037] refer to Figures 1-14As shown, an embodiment of the present invention provides an atomization introduction instrument, comprising an atomization component 2, an electroporation component 3, a monitoring component and a control circuit board 4. The control circuit board 4 is electrically connected to the atomization component 2, the electroporation component 3 and the monitoring component. The control circuit board 4 is provided with a control circuit for controlling the opening and closing and / or gear adjustment of the atomization component 2 and the electroporation component 3. The atomization component 2 is configured to spray atomized medium outward, and the monitoring component is used to monitor the distance between the outlet end of the atomization component 2 and the human skin. The electroporation component 3 includes at least two electrode heads 31 arranged at intervals and with opposite polarities. The electrode head 31 is arranged at the outlet end of the atomization component 2 and can contact the skin to form an electric current that stimulates the skin.

[0038] The above-mentioned atomization introduction instrument is provided with a monitoring component so that the atomization component 2 is only turned on when the distance between the outlet end of the atomization component 2 and the human skin is within a preset range.

The two ends of the transformer are respectively connected to two electrode heads 31 with opposite polarities. When the transformer changes from a no-load state to a loaded state, that is, when the two electrode heads 31 with opposite polarities come into contact with the skin, the current value of the transformer changes. In response to the change in the current value of the transformer, the single-chip microcomputer in the control circuit board 4 controls the atomization component 2 to start, and the spray function is automatically turned on. That is, the electrode head 31 is not only used to generate current to stimulate human skin, but also used as a monitoring component, thereby reducing the manufacturing cost and occupied space of the atomization introduction instrument.

[0040] Specifically, refer to Figure 6-Figure 14As shown, the control circuit includes an on / off button, an on / off circuit, a single-chip microcomputer power supply circuit, a single-chip microcomputer, an electroporation power supply circuit, an electroporation circuit, an electroporation level control circuit, a level button, a skin contact detection circuit, and an atomization control circuit.

[0042] In other embodiments, the monitoring element may also be a distance sensor or a pressure sensor, which will not be described in detail here.

[0043] refer to Figure 1 、 Figure 2 and Figure 4 As shown, the atomization introduction instrument further includes a housing 1 , wherein a housing cavity is provided in the housing 1 , and the electroporation component 3 , the control circuit board 4 and the atomization component 2 are all provided in the housing cavity.

[0044] Specifically, the housing 1 is configured as a T-shape, comprising a vertical gripping end and a horizontal working end. The working end of the housing 1 is provided with a first through-hole and a second through-hole, the second through-hole being arranged around the first through-hole. The outlet end of the atomizing assembly 2 sprays atomized medium to the outside through the first through-hole, and the electrode head 31 is disposed in the second through-hole. More specifically, there are four second through-holes, distributed in an annular array around the periphery of the first through-hole, i.e., there are four electrode heads 31, with adjacent electrode heads 31 having opposite polarities.

[0045] In one embodiment, to reduce the difficulty of electrically connecting the electrode head 31 to the control circuit on the control circuit board 4, the control circuit board 4 is provided in a split configuration, including a first circuit board 41 and a second circuit board 42. The first circuit board 41 is provided with a spring element electrically connected to the control circuit. The first circuit board 41 is secured to the housing 1 by means including, but not limited to, screw locking or snap-fitting, and the spring element on the first circuit board 41 abuts against the electrode head 31. The second circuit board 42 is connected to the first circuit board 41 via a cable. The second circuit board 42 is provided with control buttons electrically connected to the control circuit. The control buttons include, but are not limited to, a power button and a position button for adjusting the position of the electroporation assembly 3 and the position of the atomizer assembly 2. The control buttons extend from the housing 1 through the accommodating cavity. It is understood that the formation of current in the electrode head 31 is premised on the power button being in the on state. That is, the atomizer assembly 2 and the electroporation assembly 3 are only turned on when the power button is in the on state and the electrode head 31 is in contact with human skin. It should also be noted that the first circuit board 41 is configured in a ring shape so that the outlet end of the atomizing assembly 2 can pass through and thus spray the atomized medium outward through the first through hole.

[0046] Specifically, in order to reduce the difficulty of installing the electrode head 31 on the outer shell 1, an annular limiting step 121 is provided on the end of the hole wall of the second through hole facing the first circuit board 41, and an annular limiting protrusion 311 is provided on the electrode head 31. The limiting protrusion 311 abuts against the limiting step 121 to prevent the electrode head 31 from falling out of the second through hole, while ensuring that the electrode head 31 abuts against the spring clip on the control circuit board 4.

[0047] More specifically, the housing 1 includes a main shell 11 and a first end cover 12. The main shell 11 is configured to be T-shaped, with one lateral end thereof open. The first end cover 12 is detachably arranged at the open end of the lateral end of the main shell 11 by means including but not limited to bolt connection and clip connection to cooperate with the main shell 11 to form an operating end, that is, the first through hole and the second through hole are both opened on the first end cover 12.

[0048] refer to Figure 2-Figure 4As shown, the atomizing assembly 2 includes an air pump 22, a fluid pump 23, a liquid storage bottle 24 and an atomizing head 21, wherein the atomizing head 21 is provided with an atomizing chamber 211, the atomizing chamber 211 having an atomizing outlet 214 communicating with the outside, an air inlet 212 connected to the air pump 22, and a liquid inlet 213 connected to the fluid pump 23. The air pump 22 is used to introduce high-pressure gas into the atomizing chamber 211, and the fluid pump 23 is further connected to the liquid storage bottle 24 to introduce fluid medium into the atomizing chamber 211. The fluid medium is impacted by the high-pressure gas in the atomizing chamber 211 and is thereby atomized to form an atomized medium.

[0049] Specifically, the atomizing head 21 includes an atomizing shell and an atomizing body. An atomizing chamber 211 is formed in the atomizing shell. The atomizing body is located in the atomizing chamber 211 and is provided with a fluid channel connected to the liquid inlet 213. The fluid outlet of the fluid channel is opposite to the atomizing outlet 214. The air inlet 212 is provided on the atomizing shell. After the high-pressure gas enters the atomizing chamber 211, it can be blown toward the fluid medium flowing out of the fluid outlet of the fluid channel to form an atomized medium.

[0050] In order to facilitate the replacement of the new liquid storage bottle 24 or the replenishment of the fluid medium into the liquid storage bottle 24, refer to Figure 2 and Figure 4 As shown, the housing 1 further includes a second end cover 13. One vertical end of the main housing 11 is open. The second end cover 13 is detachably arranged at the vertical end of the main housing 11 to cooperate with the main housing 11 to form a gripping end.

[0051] Specifically, the liquid storage bottle 24 and the second end cap 13 are both configured as cylindrical structures with one end open. The liquid storage bottle 24 is connected to the second end cap 13 using methods including but not limited to threaded connection and plug-in connection. In addition to sealing the end surface of the main housing 11, the second end cap 13 is also used to seal the open end of the liquid storage bottle 24. To improve the sealing performance, a sealing ring 6 is also provided between the liquid storage bottle 24 and the main housing 11.

[0052] In order to prevent the fluid medium in the liquid storage bottle 24 from flowing to the control circuit board 4 after the sealing ring 6 fails, the shell 1 also includes a partition 5, which divides the accommodating chamber into a first accommodating chamber and a second accommodating chamber. The liquid storage bottle 24 is located in the second accommodating chamber, and the control circuit board 4, the electroporation component 3 and the atomization component 2 other than the liquid storage bottle 24 are located in the first accommodating chamber. A connecting port is opened on the partition 5 for the pipeline connecting the liquid storage bottle 24 and the fluid pump 23 to pass through.

[0053] In one embodiment, the fluid pump 23 is a peristaltic pump that drains the fluid medium from the liquid storage bottle 24 through peristalsis. The peristaltic pump can recover the fluid medium within the atomizing head 21 by reversing its rotation. This prevents the atomizing outlet 214 of the atomizing head 21 from clogging due to prolonged inactivity, and prevents the fluid medium from being carried out by transient pressure changes when the fluid pump 23 stops, causing the outflowing medium to spray out and affect the user experience. Furthermore, the peristaltic pump solves the problem of the atomizing device being difficult to clean.

[0054] In one embodiment, the atomizing assembly 2 further includes a nozzle 25 having a guide channel 251 therein. The guide channel 251 includes a guide inlet extending through a first end face of the nozzle 25 and a guide outlet extending through a second end of the nozzle 25. The first end of the nozzle 25 is connected to the atomizing outlet 214 of the atomizing head 21. The atomized medium is ejected in a diverging manner from the first end of the nozzle 25 toward the second end of the nozzle 25 within the guide channel 251. Specifically, the effective passage area of ​​the nozzle 25 increases from the first end connected to the atomizing head 21 toward the second end away from the atomizing head 21, thereby expanding the contact area between the medium and human skin and improving the efficiency of the atomizing device. For example, the nozzle 25 is configured as a trumpet-shaped nozzle with a radial radius gradually increasing from the first end to the second end.

[0055] At this time, the second end of the nozzle 25 is installed on the first end cap 12 as the outlet end of the atomizing assembly 2, and the second end face of the nozzle 25 and the output end face of the electrode head 31 are kept in the same plane or the output end face of the electrode head 31 slightly protrudes from the second end face of the nozzle 25, so that the second end face of the nozzle 25 can contact the human skin, thereby enclosing the atomized medium in the nozzle 25, and the human skin can fully absorb the atomized medium. At the same time, it can further reduce the possibility of inhalation into the mouth and nose. Specifically, the nozzle 25 and the first end cap 12 are integrally formed.

[0056] 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.
