Detailed Description

For a clearer understanding of technical features, objects and effects of the present invention, a detailed description of embodiments of the present invention will be made with reference to the accompanying drawings.

Fig. 1 shows some preferred embodiments of the electrostatically atomizing device of the present invention. The electrostatic atomizing device 1 can be applied to the fields of medical treatment, beauty treatment, electronic atomization and the like. The electrostatic atomizing device 1 can atomize a liquid matrix with larger viscosity at normal temperature and high flow rate, can regulate and control the particle size of aerosol particles formed by atomization, and greatly reduces the generation of harmful substances. Specifically, the electrostatically atomizing device 1 can be made to have an adjustable range of the particle diameter of the discharged aerosol of several micrometers to several tens of micrometers by adjusting control parameters (such as flow rate, voltage, polar distance, the number of the spray heads, and aperture, etc.). Compared with the traditional electronic atomization technology (ceramic and cotton core), the electrostatic atomization technology adopted by the electrostatic atomization device 1 atomizes liquid matrixes with the same mass, the power used by the electrostatic atomization device is about 50% of that used by the traditional electronic atomization technology, and the energy consumption is greatly reduced.

It should be noted that, the above electrostatic atomization technique refers to a process in which a liquid breaks up into droplets against its own surface tension under the action of an electric field force. The implementation process of electrostatic spraying is relatively simple, and generally, only a liquid substrate with enough conductivity and moderate surface tension is required to be injected into a metal capillary; capillary turn-on dc voltage (about several kilovolts); the place several centimeters away from the capillary is the ground electrode or the negative electrode. Under the action of electric field, the liquid meniscus at the outlet of capillary tube is conical, and the tip of cone ejects very fine jet. This jet splits downstream into a fine spray of charged droplets. In view of the morphology of the liquid meniscus, this mode is known as cone-tip mode. The electrostatic spraying of the cone tip jet mode has the following advantages: the liquid drop monodispersity is good, the range of the diameter of the obtained liquid drop is wide, the nozzle is not easy to be blocked, the theoretical fog consumption ratio is extremely low, and the deposition efficiency is high. Wherein the resistivity of the liquid matrix is generally selected to be greater than 200ohm-m, more preferably greater than 250ohm-m; the surface tension of the liquid matrix is 15-50dynes/cm, more preferably 20-35dynes/cm; the liquid matrix has a dielectric constant of less than 65, more preferably less than 45; the viscosity is less than 100cp, more preferably less than 50cp.

In other embodiments, when the showerhead assembly 30 is circular in cross-section, the first direction Z may be axial and the second direction X may be radial. The body 22 has a receiving cavity 222 formed therein, and the receiving cavity 222 is used for receiving the showerhead assembly 30, the auxiliary electrode 50, and the charge removing structure 40. The end cap 21 is disposed at an end of the body 22 opposite to the opening 221. The end cap 21 is provided with an air inlet hole 211, and the air inlet hole 211 is used for allowing air to enter the accommodating cavity 222. In this embodiment, the air inlets 211 are plural, and the air inlets 211 are spaced apart and may be arranged in a line. Of course, it is understood that in other embodiments, the air intake holes 211 are not limited to a plurality, and may not be limited to a linear arrangement, and in other embodiments, the air intake holes 211 may be circumferentially arranged.

In the present embodiment, the liquid separator 31 may be substantially rectangular parallelepiped, and it is understood that the liquid separator 31 is not limited to be rectangular parallelepiped in other embodiments. The liquid separator 31 has a fluid passage 311 formed therein. The fluid channel 311 comprises a first channel 3111 and a second channel 3112, wherein the first channel 3111 is communicable with the reservoir 11 of the reservoir 10 for accessing the liquid matrix output from the reservoir 11. The second channel 3112 may be disposed perpendicular to the first channel 3111, the second channel 3112 being in communication with the first channel 3111 for dispensing liquid matrix to each nozzle 32. In this embodiment, the second channel 3112 is disposed longitudinally in the third direction Y. The liquid separator 31 may be in communication with the liquid storage structure 10 by providing a downcomer 312, and the first channel 3111 is partially formed in the downcomer 312.

In some embodiments, each nozzle 32 may be connected with the second channel 3112, in particular, one end of each nozzle 32 may be fixed to the second channel 3112, and may be in communication with the second channel 3112. The plurality of nozzles 32 may be spaced along the length of the second channel 3112 to form a linear array. In this embodiment, the nozzle 32 may be a capillary metal tube, and in particular, the nozzle 32 may be a metal needle tube. It will be appreciated that in other embodiments, the second channel 3112 may be annular in shape, such that the plurality of nozzles 32 may be circumferentially arranged.

In some embodiments, the length of each nozzle 32 may be different. In this embodiment, the electrostatic atomizing device is formed with a first spray region and a second spray region in the length direction of the second channel 3112, and the number of the second spray regions may be two, and the two second spray regions are disposed on opposite sides of the first spray region. Of course, it will be appreciated that in other embodiments, the second spray zone may be one, and may be located on one side of the first spray zone. In this embodiment, the length of the nozzle 32 in the first spraying area extending in the first direction Z is longer than the length of the nozzle 32 in the second spraying area extending in the first direction Z, that is, the arrangement of the nozzles 32 may be long in the middle and short on both sides, so as to ensure that the electric field between the spray head assembly 30 and the auxiliary electrode 50 is uniform, and the spraying is stable, that is, each nozzle 32 may spray the first aerosol particles with the first charge. Specifically, in some embodiments, the total number of the nozzles 32 may be 11, and the lengths of the nozzles 32 sequentially arranged in the third direction Y are 6,7,8,9, 10, 11, 10,9,8,7,6mm, so that aerosol particles with a particle size of less than 2 microns can be ejected at a flow rate of 0.1ml/min when a voltage of less than 1 v is applied. Of course, it will be appreciated that in other embodiments, the plurality of nozzles 32 may be equally disposed.

The showerhead assembly 30 may be energized by a first high voltage and under the influence of the first high voltage to form first aerosol particles having a first charge and be ejected through the nozzle 32. In this embodiment, the first high voltage power may be a positive high voltage power. The first charge may be positively charged, i.e. the first aerosol particles ejected from the nozzle 32 are positively charged. Of course, it will be appreciated that in other embodiments, the first high voltage may also be a negative high voltage and the first charge may also be a negative charge.

In some embodiments, as shown in fig. 6, the charge removing structure 40 may be in a sheet shape and may be disposed parallel to and spaced apart from the auxiliary electrode 50. The cross-section of the static elimination structure 40 and the liquid separator 31 may lie in the same plane. The flow direction of the second charged ion wind generated by the de-electrification structure 40 is consistent with the flow direction of the first aerosol particles with the first charges sprayed by the spray head assembly 30, namely the first aerosol particles with the first charges are sprayed towards the opening in the Z direction, so that the sprayed first aerosol particles with the first charges can be better neutralized, the adsorption of the first aerosol particles with the first charges on each component is reduced, and the electrostatic atomization device can stably operate for a long time.

In some embodiments, the charge removing structure 40 includes a sheet-like body 41 and a plurality of ion generating portions 42. The sheet-like body 41 may be a metal sheet and may be generally rectangular. The length direction of the sheet-like body 41 may be parallel to the third direction Y, the width direction of the sheet-like body 41 may be parallel to the first direction Z, and the thickness direction of the sheet-like body 41 may be parallel to the second direction X. Of course, it will be appreciated that in other embodiments, the sheet-like body 41 may not be limited to being rectangular, and in other embodiments, the sheet-like body 41 may be formed into a ring by winding. The plurality of ion generating portions 42 are disposed at a side of the sheet-like body 41 facing the opening 221, and each ion generating portion 42 may extend in the first direction Z. In some embodiments, the plurality of ion generating portions 42 are disposed at intervals along the length direction of the sheet-like body 41, and each ion generating portion 42 may be zigzag, and the plurality of ion generating portions 42 may be formed by laser marking through a conductive film. The length of the sheet-like body 41 may be 20mm, the interval between adjacent ion generating portions 42 may be 2mm, and the thickness of each ion generating portion 42 may be 100 μm. Of course, it will be appreciated that in other embodiments, the length of the sheet-like body 41 is not limited to 20mm, the spacing between adjacent ion generating portions 42 is not limited to 2mm, the thickness of each ion generating portion 42 is not limited to 100 microns, and the dimensions of the sheet-like body 41 and ion generating portions 42 may be determined according to particular needs. In the present embodiment, the extending direction of each ion generating portion 42 is the same as the extending direction of the nozzle 32, that is, the flow direction of the generated ion wind with the second electric charge coincides with the flow direction of the first aerosol particles ejected from the nozzle 32.

In some embodiments, the de-electrification structure 40 ionizes the air in the housing cavity 222 by switching in a second high voltage and by the ion generating portion 42 to form an ion wind with a second charge. The ion wind is ions that flow in the space and are ionized to form a set charge, not gas molecules. In this embodiment, the second high voltage electric power is negative high voltage electric power, the second electric charge may be negative electric power, that is, the ion wind is negative ion wind, specifically, the negative ion may be negative oxygen ion, which may be formed by combining free electrons with oxygen molecules in the air, and so the negative oxygen ion is selectively formed, because the negative oxygen ion can effectively strengthen cilia movement of the airway mucosa epithelium, affect activity of respiratory enzymes in the epithelium, improve secretion function of alveoli and ventilation function of the lung, relieve bronchospasm, increase vital capacity, adjust respiratory rate, relieve cough, and the like. The negative ions can also promote regeneration of nasal mucosa epithelial cells and restore the secretion function of the mucosa. The health care product has good effects on diseases such as asthma, tracheitis, pertussis of children and the like, and the negative ions can also enhance the immunity of the human body, improve the self-healing power of the human body, effectively prevent and treat diseases such as diabetes, tumors and the like, and are ideal choices for daily health care of people. That is, negative ions are generated while spraying, and the side effects for the user are relatively small, even none, but rather beneficial to the body of the user.

In the present embodiment, the electricity removing structure 40 may employ an anion generating device, the electricity removing structure 40 is not limited to the design of the present invention, and other electricity removing structures capable of generating anion wind may be used in the present invention, such as carbon brushes. In other embodiments, the charge removal structure 40 may be a positive ion generating device when the first charge is negative, and the second charge may be positive.

In some embodiments, the auxiliary electrode 50 is sheet-like and sized to fit the size of the liquid separator 31, and may be 100 microns thick and generally rectangular. The auxiliary electrode 50 is parallel to and spaced from the side of the liquid separator 31 opposite to the auxiliary electrode 50, and the other opposite plane of the auxiliary electrode 50 is parallel to and spaced from the static eliminating structure 40.

In this embodiment, the surface of the auxiliary electrode 50 may be coated with an insulating structure. Specifically, the surface of the auxiliary electrode 50 may be coated with a heat shrink tube, so that the auxiliary electrode 50 is insulated from the static eliminating structure 40 and/or the liquid separator 31. Of course, it will be appreciated that in other embodiments the insulating structure may not be limited to a heat shrink tube, and in other embodiments the insulating structure may be an insulating coating or sleeve, or the like.

In some embodiments, the auxiliary electrode 50 is grounded, and the nozzle 32 can be connected to a positive high voltage (+3.5- +8 kv), and a strong electric field is formed between the positive high voltage (+3.5- +8 kv), so as to ensure the formation of a spray in a cone-tip jet mode. The charge removing structure 40 is connected with negative high voltage (about-300 v to-500 v) to generate negative ions and neutralize positive charges carried by the first aerosol particles. In some embodiments, the auxiliary electrode 50 also has another function of isolating the first high voltage generating structure 100 and the second high voltage generating structure 110, so as to avoid the air between the first high voltage generating structure 100 and the second high voltage generating structure 110 from being broken down to connect the positive electrode and the negative electrode, and pull arc discharge to generate potential safety hazard.

In some embodiments, the showerhead assembly 30, the auxiliary electrode 50, and the static elimination structure 40 may be stacked in the second direction X to form a sandwich-like structure, so that space may be saved, the overall structure of the electrostatic atomizing device may be more compact, and the miniaturized design of the electrostatic atomizing device may be facilitated.

The extraction structure 60 may be grounded, and is used to cooperate with the showerhead assembly 30 connected with the first high voltage to form an electric field, so as to pull out a portion of the first aerosol particles with the first charges, which are easily adsorbed on the auxiliary electrode 50, thereby reducing the adsorption and preventing the occurrence of the liquid accumulation and discharge phenomenon.

In some embodiments, the extraction structure 60 is disposed obliquely downstream of the aerosol particle ejection direction, and in some embodiments, the extraction structure 60 and the spray head assembly 30 may be 10-15mm apart in the first direction Z, and in particular, the extraction structure 60 and the orifice of the nozzle 32 may be 10-15mm apart in the first direction Z. In some embodiments, the distance between the extraction structure 60 and the showerhead assembly 30 in the second direction X may be 0-10mm. Specifically, the distance between the lead-out structure 60 and the spout of the nozzle 32 in the second direction X is 0-10mm.

In some embodiments, the lead-out structure 60 may be disposed lengthwise and may protrude in a convex arc away from the showerhead assembly 30. In some embodiments, the lead-out structure 60 may be a silicone wire having a set curvature. The non-straight silicone wire is chosen to ensure that the distance of the silicone wire from each nozzle 32 is comparable. The silica gel layer of the silica gel wire is insulated, but does not change the electric field, is smooth, does not form local high electric field, and is helpful for reducing adsorption. By providing the silica gel lead, there is substantially no adsorption on the auxiliary electrode 50, while there is only a small adsorption on the silica gel lead.
