In addition, the combination of the ultrasonic atomization structure and the static electricity generation structure in the ultrasonic electrostatic spraying device provided by the disclosure can realize the effect of atomizing the liquid medium twice, so that the fog drops emitted from the ultrasonic electrostatic spraying device are finer and smoother, and can be more easily applied to a target area of a target object.

An ultrasonic electrostatic atomizer provided in an embodiment of the present disclosure is described below with reference to the drawings.

Fig. 1 and 2 are exploded views of an ultrasonic electrostatic atomizer provided according to an example of the embodiment of the present disclosure. As shown in fig. 1 and 2, the ultrasonic electrostatic atomizer includes a container 100, an ultrasonic atomizing structure 200, and an electrostatic generating structure 300. The container 100 is configured to hold a liquid medium, for example, the liquid medium may be purified water, lotion, essence, etc. for caring face, and may also be a medicine for treating patients with asthma, bronchitis, emphysema, etc. The ultrasonic atomization structure 200 is located at an outlet side of the container 100, and the ultrasonic atomization structure 200 includes an ultrasonic atomization sheet 210, and the ultrasonic atomization sheet 210 is configured to atomize the liquid medium passing through the ultrasonic atomization sheet 210 into mist droplets. The static electricity generating structure 300 is located at an outlet side of the container 100, and is configured to charge the mist droplets emitted from the ultrasonic electrostatic atomizer. The ultrasonic electrostatic atomizer further includes at least one circuit board 400, and the ultrasonic atomizing structure 200 and the static electricity generating structure 300 are electrically connected to the at least one circuit board 400. The ultrasonic electrostatic spraying device provided by the embodiment of the disclosure combines the ultrasonic atomization and the electrostatic loading mode, so that the ultrasonic electrostatic spraying device can spray electrostatically charged droplets, the adsorption efficiency of the droplets on the front surface, the side surface or even the back surface of a target object is improved, the charged droplets (such as nutrients or medicaments and the like) sprayed by the ultrasonic electrostatic spraying device are adsorbed to the target area of the target object to the maximum extent, and waste is avoided. In addition, the combination of the ultrasonic atomization structure and the static electricity generation structure in the ultrasonic electrostatic spraying device provided by the disclosure can realize the effect of atomizing the liquid medium twice, so that the fog drops emitted from the ultrasonic electrostatic spraying device are finer and smoother, and can be more easily applied to a target area of a target object.

For example, the ultrasonic atomization structure 200 and the static electricity generation structure 300 share the same circuit board 400. The ultrasonic electrostatic spraying device provided by the embodiment of the disclosure can spray electrostatically charged droplets by combining the ultrasonic atomization and electrostatic loading modes, so that the adsorption efficiency of the droplets on the front surface, the side surface or even the back surface of a target object is improved, the charged droplets sprayed by the ultrasonic electrostatic spraying device are adsorbed to the target area of the target object to the maximum extent, and waste is avoided; meanwhile, the ultrasonic atomization structure and the static electricity generation structure share the same circuit board, so that the spatial layout of the ultrasonic static electricity spraying device is compact, the minimization of the device is realized, and the ultrasonic static electricity spraying device is convenient to carry outside.

For example, the ultrasonic electrostatic spraying device provided by the embodiment of the disclosure may be a beauty instrument, and when the liquid medium is pure water, lotion, essence water, or other liquid for caring the face, the liquid medium charges the mist droplets to increase the adsorbability of the mist droplets to enhance the spraying effect, for example, the mist droplets are more three-dimensionally adsorbed to the facial skin.

For example, the ultrasonic electrostatic spraying device provided by the embodiment of the disclosure can be a medical sprayer, and when the liquid medium is a medicament, the medicament droplets can effectively act on the target part of the target object by charging the droplets, so that the medicament effect is enhanced, and the waste is reduced.

The charged fog drops after ultrasonic atomization have remarkably improved adsorptivity, and the effects of local infection spraying, local wound spraying and eye spraying on the skin are remarkably improved. For respiratory diseases, rhinitis is taken as an example, rhinitis pathogens are located in the nasal cavity atrium, however, the conventional atomized medicament cannot be effectively deposited in the nasal cavity atrium, liquid medicine droplets can enter the lung along with respiration, and the treatment effect needs to be improved. However, the liquid medicine fog drops atomized by ultrasonic and electrostatic atomization carry charges and can be actively attached to the nasal cavity atrium, so that the treatment effect is improved. In addition, for lung diseases, the liquid medicine fog drops can not be effectively deposited under the rejection effect of lung villi and are discharged out of the body along with respiration, but the fog drops carrying static can overcome the rejection effect of the lung villi, are adsorbed to the lung, and improve the treatment effect of the lung diseases. The deposition of the liquid medicine fog drops on different parts of the respiratory tract can be controlled by controlling the diameter of the fog drops and the electric charge quantity carried by the fog drops, so that the aim of accurate and efficient treatment is fulfilled.

For example, the ultrasonic atomization sheet 210 includes a screen with fine holes, and when the liquid medium flows through the ultrasonic atomization sheet 210, the ultrasonic atomization sheet 210 ultrasonically vibrates the liquid medium, and the liquid medium is squeezed out by the fine holes, so that a large amount of mist droplets are generated. For example, the ultrasonic atomization sheet 210 is formed by bonding a ceramic sheet and a metal sheet with micropores, and the outer portion of the ultrasonic atomization sheet 210 may be sleeved with a sealing ring to prevent liquid drops from entering the device.

For example, as shown in fig. 1 and 2, the ultrasonic electrostatic atomizer further includes a holder portion 500, the holder portion 500 including a passage 510, the passage 510 being connected to the outlet 110 of the container 100. For example, the holder portion 500 may be screw-coupled with the outlet 110 of the container 100. For example, a sealing ring 810 may be provided between the bracket portion 500 and the outlet 110 of the container 100 to prevent the liquid medium from overflowing.

For example, as shown in fig. 1 and 2, the ultrasonic electrostatic atomizer further includes a nozzle holder 600 located at an outlet side of the channel 510 in the holder portion 500 and connected to the holder portion 500. For example, the nozzle mount 600 may be connected to the holder portion 500 by a snap 601. For example, as shown in fig. 1 and 2, the nozzle mount 600 includes an opening 610, the opening 610 is disposed opposite to the outlet of the channel 510, the ultrasonic atomization sheet 210 is disposed between the outlet of the channel 510 and the nozzle mount 600, and the opening 610 exposes the ultrasonic atomization sheet 210. For example, the size of the openings 610 is larger than the size of the mesh in the ultrasonic atomization sheet 210. For example, the opening 610 of the nozzle seat 600 is opposite to the outlet of the channel 510, which means that the liquid medium is transmitted to the ultrasonic atomization sheet through the channel 510, and the atomized droplets are ejected through the opening of the nozzle seat.

For example, as shown in fig. 1 and 2, the ultrasonic electrostatic atomizer further includes a power supply 700 disposed on the holder portion 500 and configured to be electrically connected to the circuit board 400. For example, the power supply 700 may supply power to the circuit board 400, the ultrasonic atomizing structure 200, and the static electricity generating structure 300. For example, power supply 700 may be a battery. For example, the power supply 700 may provide several hundreds volts to several kilovolts, or several tens of thousands of volts to the static electricity generating structure 300 after being boosted by the boosting module.

For example, as shown in fig. 1 and 2, the bracket portion 500 further includes a circuit board slot 520 and a power supply slot 530 located on a side of the channel 510 away from the container 100, the power supply 700 is inserted into the power supply slot 530 to facilitate fixing of the power supply 700, and the circuit board 400 is inserted into the circuit board slot 520 to facilitate fixing of the circuit board 400. For example, circuit board 400 is snap-fit to circuit board slot 520.

In the embodiment of the disclosure, the ultrasonic atomization sheet is fixed between the channel outlet of the bracket part and the nozzle seat, and the circuit board and the power supply are clamped and installed in the clamping groove of the bracket part, so that the installation mode of the ultrasonic atomization sheet, the circuit board and the power supply can be simplified, and the ultrasonic electrostatic spraying device can be thinned as much as possible.

For example, as shown in fig. 1 and 2, the power supply 700 and the ultrasonic atomization sheet 210 are respectively located at both sides of the circuit board 400, so that the space of the ultrasonic electrostatic atomizer can be maximally utilized.

For example, as shown in fig. 1 and 2, in a direction perpendicular to the main board surface of the circuit board 400 (e.g., a direction perpendicular to the surface of the ultrasonic blade), the ultrasonic blade 210 does not overlap the circuit board 400, and the power supply 700 overlaps the circuit board 400.

For example, there is no gap between the power supply 700 and the circuit board 400, or the gap is small, which may improve the compactness of the structure. For example, a flexible buffer may be disposed between the power supply 700 and the circuit board 400 to prevent the power supply from being squeezed or to prevent the gap between the power supply and the circuit board from being too large to cause the power supply to be positioned insecurely.

For example, the distance between the circuit board 400 and the side of the channel 510 close to the circuit board 400 is set to be small, and the size of the bracket portion can be reduced as much as possible to reduce the volume of the ultrasonic electrostatic spraying apparatus.

For example, the circuit board 400 may be a Printed Circuit Board (PCB). For example, fig. 3 is a block diagram of a circuit board in an ultrasonic electrostatic spraying apparatus provided in an embodiment of the present disclosure. As shown in fig. 3, the circuit board 400 may include a voltage boosting module 410, an atomization control module 420, and a switch module 430, the switch module 430 is configured to be electrically connected to the voltage boosting module 410 and the atomization control module 420 to control the switches of the two, the voltage boosting module 410 is electrically connected to the static electricity generating structure 300 and configured to apply a voltage to the static electricity generating structure 300 to control the operating state of the static electricity generating structure 300; the atomization control module 420 is electrically connected to the ultrasonic atomization plate 210 and configured to apply a voltage to the ultrasonic atomization plate 210 to control an operation state of the ultrasonic atomization plate 210.

For example, as shown in fig. 1 to 3, a first switch 401 and a second switch 402 are disposed on the circuit board 400, the first switch 401 and the second switch 402 may be part of the switch module 430, the first switch 401 is used for controlling the switches of the ultrasonic atomization structure 200, and the second switch 402 is used for controlling the switches of the static electricity generation structure 300. For example, when the first switch 401 is turned on, the atomization control module 420 is activated, and the ultrasonic atomization sheet 210 starts to work; when the second switch 402 is turned on, the voltage boost module 410 is turned on, and the static electricity generating structure 300 starts to operate. The on and off times of the first switch and the second switch may be controlled by a user.

For example, the voltage boosting module and the atomization control module can be controlled by two independent switches, so that only the ultrasonic atomization sheet can work, and the droplets sprayed from the ultrasonic electrostatic spraying device can be uncharged.

The embodiment of the disclosure is not limited thereto, and the two switches may be associated, for example, the voltage boosting module may be turned on by the switch only after the atomization control module is turned on, that is, the static electricity generating structure may start to operate only after the ultrasonic atomization sheet operates, and the static electricity generating structure may not operate alone.

For example, the voltage boosting module and the atomization control module can be controlled by the same switch, when the switch is in an on state, the voltage boosting module is also turned on while the atomization control module is turned on, and the ultrasonic atomization sheet and the static electricity generation structure work simultaneously.

For example, as shown in fig. 1 and 2, the first switch 401 and the second switch 402 may be located on the same side of the circuit board 400, and the power supply 700 is located on the other side of the circuit board 400 to achieve efficient use of space in the ultrasonic electrostatic atomizer.

For example, the ultrasonic electrostatic spraying device may further include an indicator light (not shown) connected to the second switch 402, and when the second switch 402 is turned on, the indicator light is turned on to alert a user that the sprayed droplets are charged with static electricity.

For example, the circuit board may further include a central processing module, in which a control program is written, and the ultrasonic atomization sheet and the static electricity generation structure may be controlled according to a scheme specified by a user. For example, the amount of mist droplets discharged from the ultrasonic electrostatic atomizer, the amount of charge of mist droplets, or the like may be adjusted.

In the embodiment of the disclosure, the switch module, the boosting module and the atomization control module are integrated on the same circuit board, so that the whole layout of the ultrasonic electrostatic spraying device is small and flexible, and the installation is simpler and more convenient.

For example, at least one of the charge level display module 450 and the charging module 440 may be further integrated on the circuit board 400, so that the remaining charge level in the ultrasonic electrostatic spraying device can be displayed and/or the ultrasonic electrostatic spraying device can be charged. For example, the power display module 450 and the charging module 440 may be both located at the bottom of the circuit board 400 and respectively disposed at two sides of the bottom of the circuit board 400, but not limited thereto, for example, the charging module may also be located at the same side as the switch module or the power supply. In the embodiment of the disclosure, the switch module, the boosting module, the atomization control module, the electric quantity display module and the charging module are all integrated on the same circuit board, so that the overall layout of the ultrasonic electrostatic spraying device is smaller and more flexible.

For example, as shown in fig. 1 and fig. 2, the static electricity generating structure 300 is located on the mist outlet side of the ultrasonic atomizing structure 200, and the static electricity generating structure 300 is configured to charge the mist passing through the static electricity generating structure 300, that is, after the liquid medium in the container 100 is atomized into mist through the ultrasonic atomizing structure 200, the mist is charged after passing through the static electricity generating structure 300. In at least one example of the embodiment of the present disclosure, the static electricity generating structure may not only provide static electricity for the mist droplets, but also perform secondary atomization on the mist droplets, so as to further reduce the size of the mist droplets, and further make the mist droplets ejected by the ultrasonic electrostatic spraying device finer and smoother, so as to improve the absorption effect of the skin of a user or the treatment effect of lung diseases of a patient.

For example, fig. 4 is a schematic structural diagram of a nozzle seat in the ultrasonic electrostatic spraying device shown in fig. 1. As shown in fig. 1, 2 and 4, in an example of the embodiment of the present disclosure, the static electricity generating structure 300 includes a ring member 310, and the voltage boosting module 410 of the circuit board 400 is configured to be electrically connected to the ring member 310 to apply a voltage to the ring member 310. The nozzle mount 600 includes a ring member notch 602, the ring member 310 is inserted in the ring member notch 602, and the ring member 310 surrounds the opening 610 of the nozzle mount 600. The annular component is clamped in the annular component clamping groove of the spray head seat, so that the annular component can be conveniently installed and replaced.

For example, as shown in fig. 1 and fig. 2, when a first switch 401 on the circuit board 6 is pressed, the ultrasonic atomization sheet 210 starts to atomize the liquid medium to form droplets, and at this time, a second switch 402 on the circuit board 400 is pressed, the voltage boosting module on the circuit board 400 is started, the annular component 310 electrically connected to the voltage boosting module is applied with a certain voltage, and when the droplets pass through the annular region of the annular component 310, the electrostatic induction is applied with charges to charge the ejected droplets.

For example, as shown in fig. 1, 2 and 4, the ring member 310 is inserted into the ring member clamping groove 602, and the ring member 310 surrounds the opening 610 of the nozzle seat 600, so that the mist can pass through the center of the ring member 310, thereby enhancing the electrification effect of the mist as much as possible.

For example, the size of the screen in the ultrasonic atomization sheet 210 is not larger than the diameter of the inner ring of the ring member 310.

For example, the ultrasonic atomization sheet 210 includes a micropore area including a plurality of micropores, the annular part 310 includes an open area, an orthographic projection of the micropore area in the annular part is completely located within the open area, a maximum dimension of the micropore area is a first dimension, a maximum dimension of the open area is a second dimension, and a ratio of the second dimension to the first dimension is 1.2-20. For example, the ratio of the second dimension to the first dimension is 2 to 15. For example, the ratio of the second dimension to the first dimension is 5 to 10.

For example, the shape of the microporous region may be circular, and the first size refers to the diameter of the circle; for example, the shape of the microporous region may be elliptical, and the first dimension refers to the major axis of the ellipse; for example, the shape of the microporous region may be rectangular, and the first dimension refers to a diagonal of the rectangle. The embodiments of the present disclosure are not limited thereto, and the micro-pore region may also be an irregular shape, and then the first size refers to the maximum length in the irregular shape.

For example, the annular member is shown schematically as a circular ring, the open area is circular and the second dimension refers to the diameter of the circle. Of course, the embodiment of the present disclosure is not limited thereto, the opening area may also be an ellipse, and then the second size refers to a major axis of the ellipse; for example, the shape of the open area may be rectangular, and the second size refers to a diagonal of the rectangle.

For example, the shape of the microporous region may be the same as the shape of the opening region, such as a regular shape, e.g., a circle, an ellipse, or a rectangle, but is not limited thereto, and the shape of the microporous region may be different from the shape of the opening region, such as an ellipse or a rectangle, and a circle.

For example, the distance between the ultrasonic atomization sheet 210 and the annular member 310 is 0 to 100 mm. For example, the distance between the ultrasonic atomization sheet 210 and the annular member 310 may be 5 to 80 mm. For example, the distance between the ultrasonic atomization sheet 210 and the annular member 310 may be 20 to 50 mm. According to the embodiment of the disclosure, the distance between the ultrasonic atomization sheet and the annular component is set, so that the electrification effect of the droplets can be enhanced as much as possible while the compactness of a plurality of structures in the device is improved.
