Description

Technical Field

[0001] The present invention relates to the technical field of negative ions, and in particular to a water negative ion generating device and method based on water droplet tip discharge. Background Art

[0002] The negative ion generators currently available on the market are generally air negative ion generators, which use high-voltage corona discharge to increase the negative ion content in the air, thereby improving air quality and promoting health. Their structure generally uses a thyristor inverter high voltage and a suspended discharge needle for corona discharge.

[0003] The Chinese patent application with publication number CN115986569A discloses a water negative ion generating device, which includes a water negative ion injection structure and an ionization device, wherein the water negative ion injection structure includes an injector based on an injector plate and a piezoelectric ceramic plate, so that when a voltage of a predetermined frequency and peak value is applied to the injector plate and the piezoelectric ceramic plate, the injector plate will generate high-frequency vibrations and hit the water droplets, thereby causing the water to resonate and produce tiny water droplets, and the tiny water droplets will rub against the injector plate at high frequency while being generated, so that the tiny water droplets are further negatively charged to form negative ions and diffuse from the injection hole of the injector plate into the environment, and the ionization device generates negative ions such as negative oxygen ions in the form of ionized air, and these negative ions supplement the charge of the negative ions generated by the injector. It can be seen that the above-mentioned water negative ion generating device requires an additional air ionization device to be added near the water negative ion injection structure to increase the negative ion concentration, so that its structure is relatively complex. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a method for generating water negative ions based on water droplet tip discharge, which comprises the steps of:

[0005] (a) spraying water mist through a water mist spraying unit; and

[0006] (b) The conductor in contact with water of the water mist spraying unit is electrically connected to a high-voltage circuit module to provide a high-voltage electric field, thereby ionizing the water mist to generate negative ion water mist.

[0007] This method loads a conductor in contact with water with high voltage, so that the sprayed tiny water droplets are ionized based on the tip discharge principle to generate negative ion water mist.

[0008] Preferably, the water mist spraying unit sprays water mist in a manner selected from piezoelectric ceramic spray, venturi spray, high-pressure atomization spray, and nano spray.

[0009] The water mist spraying method of the present invention can be in various forms, which only requires providing a conductor that can contact water and can conduct electricity under the high voltage provided by the high-voltage circuit module to stimulate the ionization of tiny water droplets.

[0010] The present invention also provides a water negative ion generating device based on water drop tip discharge, which comprises:

[0011] a water supply assembly for storing water; and

[0012] A negative ion water mist generating component; wherein the negative ion water mist generating component includes a water mist spraying unit and a high-voltage generating unit, the water mist spraying unit is used to spray water from the water supply component into water mist, and the water mist spraying unit includes a conductor that contacts water, and the high-voltage generating unit includes a high-voltage circuit module, the conductor contacts the water provided by the water supply component to the water mist spraying unit and the conductor is electrically connected to the high-voltage circuit module to generate a high-voltage electric field environment, so that the water mist generated by the water mist spraying unit is ionized to generate negative ion water mist.

[0013] The water negative ion generating device loads a conductor in contact with water with high voltage, so that the sprayed tiny water droplets are ionized based on the tip discharge principle to produce negative ion water mist, which is different from the existing technology of using a discharge needle to ionize the air to produce air negative ions.

[0014] Preferably, the water mist spraying unit is selected from one of a piezoelectric ceramic spray device, a venturi spray device, a high-pressure atomizing spray device, and a nano spray device.

[0015] It is understandable that the device of the water mist spraying unit of the present invention only needs to provide a conductor that can contact water and can conduct electricity under the high voltage provided by the high-voltage circuit module to stimulate the ionization of tiny water droplets.

[0016] Preferably, the water mist spray unit includes an annular piezoelectric sheet, the conductor is overlapped with the piezoelectric sheet and the two are insulated, the conductor has micropores, and when the piezoelectric sheet is input with voltage, it drives the conductor to vibrate so that the conductor contacts the water to cause the water to vibrate and produce tiny water droplets, and the tiny water droplets further rub against the conductor to produce negative ion droplets, and the conductor also generates a high-voltage electric field environment through the high-voltage circuit module, so that the negative ion droplets are further ionized, thereby producing the water negative ion water mist.

[0017] The conductor of the present invention therefore has three functions. The first function is that it is driven by the piezoelectric sheet to vibrate, thereby vibrating the water in contact with it and ejecting tiny water droplets from its micropores. The second function is that the conductor is made of a material that loses electrons more easily than water, so it loses electrons more easily when rubbed with tiny water droplets, thereby charging the tiny water droplets and generating negative ion droplets. The third function is that the conductor provides a high-voltage electric field environment because it is directly electrically connected to the high-voltage circuit module, so that the negative ion droplets are further ionized by the high-voltage electric field, so that the negative ion water mist generating component of the present invention can generate high-concentration water negative ion water mist.

[0018] Preferably, the water negative ion generating device further includes a control circuit board and a power module, the power module supplies power to the control circuit board, the same side of the piezoelectric piece is electrically connected to the control circuit board through two electrode connecting wires, and the conductor is electrically connected to the high-voltage circuit module through a connecting wire.

[0019] The piezoelectric chip of the water mist spray unit is connected to the positive and negative electrodes, thereby generating vibration when a voltage is input. The conductor is insulated from the piezoelectric chip to facilitate the connection of high voltage and thus generate a high-voltage electric field environment. In this way, the water mist spray unit can simultaneously receive the excitation voltage for driving vibration and the high-voltage circuit for generating the high-voltage electric field.

[0020] Preferably, the negative ion water mist generating assembly further includes a water guide cavity, the water mist spraying unit is installed in the water guide cavity, the water guide cavity has a connected water guide channel and a water storage channel, wherein the water of the water supply assembly reaches the water storage channel via the water guide channel to contact the conductor.

[0021] The water is guided to contact the conductor through the water guiding cavity, thereby facilitating the conductor to interact with the water to generate water mist.

[0022] Preferably, the water negative ion generating device further includes a blowing component, and the water guide cavity further has a ventilation hole. The blowing component blows air toward the negative ion water mist generating component and blows it out from the ventilation hole to carry the water negative ion mist generated by the negative ion water mist generating component and enable the water negative ion mist to migrate to the external environment.

[0023] By blowing air through the blowing component, the negative ion water mist generated by the negative ion water mist generating component migrates farther, so that the negative ions can be diffused in a larger area of ​​the environment.

[0024] Preferably, the negative ion water mist generating assembly further includes a buffer element, which is assembled in the water-conducting cavity to provide a buffering effect to the conductor when the conductor vibrates.

[0025] Preferably, the buffer element is made of elastic material and includes an annular fixing plate, a buffer plate and a connecting plate. The buffer plate extends inwardly and integrally to the annular fixing plate through the connecting plate. The water mist spray unit is buried in the inner cavity formed by the buffer element. The position of the buffer plate corresponds to the central area of ​​the conductor having multiple micropores. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The terms and words used in the following description are not limited to the literal meanings, but are merely used by the inventor to enable a clear and consistent understanding of the present application. Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of the present application is provided for illustration purposes only and not for the purpose of limiting the present application as defined by the appended claims and their equivalents.

For example, a first component could be referred to as a second component, and similarly, a second component could be referred to as a first component without departing from the teachings of the present inventive concept. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0034] The terms used herein are for the purpose of describing various embodiments only and are not intended to be limiting. As used herein, the singular is intended to include the plural, unless the context clearly indicates otherwise. It will also be understood that the terms "comprising" and / or "having" when used in this specification specify the presence of a stated feature, number, step, operation, component, element, or combination thereof, and do not preclude the presence or addition of one or more other features, numbers, steps, operations, components, elements, or groups thereof.

[0035] like Figures 1 to 6 The figure shows a water negative ion generating device based on water droplet tip discharge according to a preferred embodiment of the present invention, which includes a negative ion water mist generating component 10, a water supply component 20, a blowing component 30, a housing 40 and a control component 50, wherein the negative ion water mist generating component 10, the water supply component 20, the blowing component 30 and the control component 50 are installed in the housing 40, the water supply component 20 is used to supply water to the negative ion water mist generating component 10, so that when the negative ion water mist generating component 10 works under the control of the control component 50, the water is rubbed and discharged at a high frequency to generate high-concentration water negative ions, and the blowing component 30 draws air into the water negative ion generating device under the control of the control component 50, and blows the water negative ions generated by the negative ion water mist generating component 10 to the outside to carry the water negative ions to the environment.

[0036] It is understandable that the water negative ion generating device of the present invention can be assembled into a water negative ion generating machine, or it can be used as a module and integrated into other air conditioning equipment such as air conditioners, vehicle-mounted purification equipment, fresh air systems, etc.

[0037] like Figures 2 to 4 As shown in the figure, the negative ion water mist generating component 10 includes a water mist spraying unit 11 and a high voltage generating unit 12, wherein the water mist spraying unit 11 can spray out water, and during the spraying process, the local surface of the water droplets will form a place with a larger curvature to form a tip, and the high voltage generating unit 12 provides an electric field environment for such water droplets so that the water droplets are ionized to generate negative ion water mist.

[0038] More specifically, the water mist spraying unit 11 includes a conductor 111 in contact with water, and the high-voltage generating unit 12 includes a high-voltage circuit module 121 and a connecting wire 122, wherein the connecting wire 122 is used to electrically connect the conductor 111 to the high-voltage circuit module 121. The material used for the conductor 111 can conduct electricity within the high voltage range generated by the high-voltage circuit module 121, so that the conductor 111 in contact with water is applied with high voltage to make the sprayed water droplets discharge in the electric field environment, thereby forming negatively charged water mist, i.e., negative ion water mist.

[0039] It is understood that the water mist spraying unit 11 can be any device capable of spraying water mist, including but not limited to a piezoelectric ceramic spray device, a venturi tube spray device, a high-pressure atomizing spray device, and a nano-spray device. A piezoelectric ceramic spray device refers to a device that atomizes water droplets based on the high-frequency vibration of a piezoelectric ceramic plate. A venturi tube spray device refers to a device that produces water mist by accelerating the airflow carrying water molecules through a venturi tube. A high-pressure atomizing spray device refers to a device that produces water mist by vaporizing water under high pressure, such as 20-50 MPa. The nano-spray device is internally provided with an ultrasonic vibration device that is excited to generate high-frequency vibration, thereby breaking down water droplets into tiny droplets to produce water mist.

[0040] That is to say, the above-mentioned piezoelectric ceramic spray device, venturi tube spray device, high-pressure atomizing spray device, and nano spray device can all be configured with a conductor 111 that can contact water, and only needs to electrically connect the conductor 111 to the high-voltage circuit module 121 through the connecting wire 122 to generate negative ion water mist based on the discharge at the tip of the water droplet.

[0041] Compared to the prior art method of using an additional ionization device to ionize the air and generate negative air ions, the negative ion water mist generating assembly 10 of the present invention directly electrically connects the high-voltage circuit module 121 to the conductor 111 that can contact water, thereby ionizing the water droplets and generating negative ion water mist. Therefore, the negative ion water mist generating assembly 10 of the present invention does not require the high-voltage ionization device that includes a negative ion brush head or a high-voltage discharge needle in the prior art. The present invention directly uses the sprayed water droplets generated by the water mist spray unit 11 as the discharge tip, so that the sprayed water droplets are directly ionized when the conductor 111 applies a high voltage to generate an electric field, thereby generating negative ion water mist.

[0042] The present invention integrates the high-voltage circuit module 121 with the water mist spray unit 11 through the connecting wire 122, so that the water mist spray unit 11 produces tiny water droplets and is ionized at the same time to obtain negative ion water mist. This is unlike the water negative ion spray structure in the prior art CN115986569A, which generates water mist that relies on capturing air negative ions ionized by the discharge needle to increase the negative ion concentration.

[0043] In this embodiment of the present invention, the water mist spraying unit 11 is illustrated by taking a piezoelectric ceramic spraying device as an example, which includes the above-mentioned conductor 111 and the piezoelectric sheet 112. The negative ion water mist generating assembly 10 further includes a water guide cavity 13 and a buffer element 14, wherein the water guide cavity 13 has a connected water guide channel 131 and a water storage channel 132, so that the water in the water supply assembly 20 can enter the water guide channel 131 and reach the water storage channel 132. The water mist spraying unit 11 and the buffer element 14 are installed in the water guide cavity 13. The conductor 111 of the water mist spraying unit 11 is a conductive sheet, which can contact the water in the water storage channel 132, and when it vibrates under the drive of the piezoelectric sheet 112, it is buffered by the buffer element 14 to reduce its noise.

[0044] It is understood that in this embodiment, the water guide channel 131 is arranged vertically, and the water storage channel 132 is arranged horizontally. In other variations, the water guide cavity 13 may also have a water guide channel of other structures, which only needs to guide the water in the water supply assembly 20 to a position where it can contact the conductor 111.

[0045] In this embodiment of the present invention, the conductor 111 is a friction plate having a central area 1111 and an outer ring area, wherein the piezoelectric plate 112 is a piezoelectric ceramic and is annular, which is attached to the outer ring area of ​​the friction plate, and the central area 1111 of the friction plate has multiple micropores 1112 to form a mesh structure.

[0046] Preferably, the conductor 111 of the present invention generates water droplets while simultaneously causing them to generate water anions through friction. The friction plate has a diameter of 10-20 mm, a central region 1111 of 1-10 mm, and 500-5000 micropores 1112. These micropores 1112 are extremely small. In the present invention, the size of micropores 1112 is less than 10 μm, and preferably, the opening size is less than 5 μm. This is because the amount of water anions generated by a water droplet is positively correlated with its negative charge density, which depends on the contact time and area with the friction plate, as well as the charge density of the friction plate. Therefore, the smaller the water droplet, the higher its average charge density, and thus the greater the amount of water anions generated. In other words, droplets with smaller diameters are more likely to generate water anions, and the concentration of these anions is higher.

[0047] In this embodiment, the control assembly 50 includes a control circuit board 51 and a power module 52, which supplies power to the control circuit board 51. The conductor 111 is electrically connected to the high-voltage circuit module 121 via a connecting wire 122. The piezoelectric sheet 112 is arranged to overlap the conductor 111, and an insulating layer is provided between the piezoelectric sheet 112 and the conductor 111 to insulate the piezoelectric sheet 112 from the conductor 111. The piezoelectric sheet 112 is ring-shaped and is connected to the control circuit board 51 of the control assembly 50 via two electrode connection wires 113, one positive and one negative.

[0048] That is to say, the water mist injection unit 11 of the piezoelectric ceramic spray device of the present invention is connected on the same side, and the piezoelectric piece 112 is connected on the same side so that the piezoelectric piece 112 vibrates when a voltage is input to the piezoelectric piece 112. In this way, the vibration of the piezoelectric piece 112 drives the synchronous vibration of the conductor 111, so that the conductor 111 contacts the water in the water storage channel 132 to vibrate the water in the water storage channel 132 and produce tiny water droplets, and these tiny water droplets further rub against the conductor 111 to produce negative ion droplets, and the conductor 111 is also applied with high voltage through the high-voltage circuit module 121, so that the high-voltage electric field environment provided by the conductor 111 causes the negative ion droplets to be further ionized based on tip discharge, thereby producing a higher concentration of water negative ion water mist.

[0049] That is, in this embodiment of the present invention, the conductor 111 has three functions. The first is that it is driven by the piezoelectric plate 112 to vibrate, thereby vibrating the water in contact with it and ejecting tiny water droplets from its micropores 1112. The second function is that the conductor 111 is made of a material that loses electrons more easily than water, and thus loses electrons more easily when rubbed against tiny water droplets, thereby charging the tiny water droplets and generating negative ion droplets. The third function is that the conductor 111 provides a high-voltage electric field environment because it is directly electrically connected to the high-voltage circuit module 121, so that the negative ion droplets are further ionized by the high-voltage electric field, thereby enabling the negative ion water mist generating assembly 10 of the present invention to produce a high-concentration water negative ion mist. The high-voltage circuit module 121 in the present invention can provide a high voltage of -2kV to -20kV.

[0050] It is understandable that the high-voltage circuit module 121 can be a separate module or integrated into the control circuit board 51, so that the control circuit board 51 can control the operation of the water mist spraying unit 11, the high-voltage circuit module 121 and the blowing assembly 30.

[0051] Preferably, the buffer element 14 of the present invention is a buffer sleeve, and the negative ion water mist generating assembly 10 is accommodated in the buffer element 14 and installed in the water guide cavity 13, so that the water mist spraying unit 11 can be electrically connected to the control circuit board 51 and driven by the power module 52 to vibrate back and forth at a high frequency, so that the water entering the water storage channel 132 rubs against the conductor 111 of the water mist spraying unit 11 to generate tiny water droplets with electric charge to generate negative ion water mist.

[0052] In this embodiment, the negative ion water mist generating assembly 10 is illustrated as including a plurality of water mist spraying units 11, and the water guide cavity 13 is arranged in a vertical direction, forming a vertical water guide channel 131 and a plurality of water storage channels 132 extending in a horizontal direction. The plurality of water mist spraying units 11 are respectively installed in the plurality of water storage channels 132, so as to rub the water stored in the corresponding water storage channels 132 to generate negative ion water mist.

[0053] It is understood that in the present invention, each water mist spray unit 11 includes a conductor 111 and at least one piezoelectric sheet 112, which can be driven to generate vibration under the control of the control circuit board 51, so that the conductor 111 and the water in the water storage channel 132 are rubbed at high frequency and the tiny water droplets are ionized to produce negative ion water mist. In another embodiment, each water mist spray unit 11 may also include two piezoelectric sheets 112 and a conductor 111, and the conductor 111 is located between two layers of piezoelectric sheets 1112. It is understood that the two piezoelectric sheets 112 and the conductor 111 constitute two friction components, and the control circuit board 51 can drive one of the friction components to be in a working state while the remaining friction component does not work due to the input voltage signal. In this way, by alternately connecting the excitation signal, the overall life of the water mist spray unit 11 becomes twice that of the water mist spray unit with a single layer of piezoelectric sheets.

[0054] It is worth mentioning that in order to ensure that the water on the conductor 111 can resonate to produce tiny water droplets and to ensure that the tiny water droplets and the conductor 111 have sufficient high-frequency friction, the voltage applied to the piezoelectric plate 112 needs to be able to drive the conductor 111 to vibrate at a high frequency. Preferably, when the voltage applied to the piezoelectric plate 112 is 110±kHz with a peak value of 60V-90V, the conductor 111 can vibrate at a high frequency and produce a high concentration of water negative ions, and the water negative ions can migrate over a long distance.

[0055] The conductor 111 is used to vibrate and impact the liquid in the water storage channel 132, thereby generating negative ions. The corresponding buffer element 14 is arranged in a corresponding manner to the conductor 111 so that when the conductor 111 vibrates to generate negative water ions, it simultaneously impacts the buffer element 14, thereby preventing the conductor 111 from impacting the water and generating noise. More specifically, when a voltage of a predetermined frequency and peak value is applied to the piezoelectric plate 112, the conductor 111 is driven to generate high-frequency vibrations and strike the buffer element 14, causing the water between the buffer element 14 and the conductor 111 to resonate and generate tiny water droplets. As the tiny droplets are generated, they rub against the conductor 111 at a high frequency between the conductor 111 and the buffer element 14, thereby further carrying a negative charge to form negative water ions, which diffuse from the micropores 1112 into the environment. The conductor 111 provides a high-voltage electric field environment to further ionize the tiny water droplets, thereby generating a negative ion mist with a high concentration of negative ions. The blowing assembly 30 blows out air and carries the water negative ions released from the micropores 1112 to diffuse toward the external environment, thereby increasing the migration distance of the water negative ions.

[0056] In this embodiment, the buffer element 14 is made of an elastic material, such as elastic silicone or elastic rubber, and includes an annular fixing plate 141, a buffer plate 142 and a connecting plate 143. The buffer plate 142 extends inwardly and integrally to the annular fixing plate 141 through the connecting plate 143. The water mist spray unit 11 is buried in the inner cavity 140 formed by the buffer element 14. The position of the buffer plate 142 corresponds to the central area 1111 of the conductor 111 having multiple micropores 1112. In this way, when the conductor 111 vibrates at high frequency, the central area 1111 having multiple micropores 1112 correspondingly impacts the buffer plate 142, thereby buffering the vibration of the conductor 111 and reducing the noise when hitting the liquid.

[0057] In another embodiment, the buffer element 14 may also be provided in the water storage channel 132 to buffer the vibration of the conductor 111. The buffer element 14 may be made of various elastic buffering materials, such as the elastic silicone or elastic rubber, or a cotton swab.

[0058] like Figures 4 and 5 As shown in FIG, the buffer element 14 further has a slot 144 for connecting the wire 122 and the electrode connection line 113.

[0059] like Figure 2 and 3As shown in FIG, the water guide cavity 13 further has a ventilation hole 133, which penetrates the water guide cavity 13 in the thickness direction, so that the wind blown by the blowing assembly 30 toward the negative ion water mist generating assembly 10 is blown out from the ventilation hole 133. Preferably, the ventilation hole 133 can be set at a central position of the water guide cavity 13, so as to be located in the center of the multiple water mist spraying units 11, so that the negative ion water mist generated by the multiple water mist spraying units 11 is carried by the wind blown out from the central ventilation hole 133 and diffused into the environment outside the device.

[0060] The housing 40 of the water droplet tip discharge-based negative ion generating device of the present invention is a shell device. The negative ion water mist generating assembly 10, the blowing assembly 30, and the control assembly 50 are arranged in the housing 40, and the water supply assembly 20 is arranged on the top of the housing 40. The blowing assembly 30 includes a fan and a filter, so that the air entering the housing 40 from the air inlet on the side of the housing 40 passes through the filter and is then sent to the negative ion water mist generating assembly 10 by the fan, carrying the negative ion water mist generated by the negative ion water mist generating assembly 10, and is ejected from the outlet provided on the side of the housing 40 to deliver a high concentration of negative water ions to the environment.
