[0002] A 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 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 by ionizing the air, and these negative ions supplement the charge of the negative ions generated by the injector.

[0003] It can be seen that the above-mentioned water negative ion generating device needs to add an air ionization device near the water negative ion injection structure to increase the negative ion concentration, wherein the center of the ionization device is at a predetermined distance from the center of the water negative ion injection structure, so that the negative oxygen ions generated by the ionization device need to migrate a predetermined distance before they can be captured by the tiny water droplets generated by the injection piece.

[0004] The water negative ion injection structure based on the injection plate and the piezoelectric ceramic plate has a certain service life, which generally does not exceed 3,000 hours.

The terms are used solely to distinguish one component from another. 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.

[0028] 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.

[0029] like Figures 1 to 3 The figure shows a negative ion water mist excitation module according to a preferred embodiment of the present invention, which includes a water mist injection structure and a high-voltage generating structure, wherein the water mist injection structure can spray water, and during the injection 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 structure provides an electric field environment for such water droplets, so that the water droplets are ionized to generate negative ion water mist.

[0030] More specifically, the water mist spraying structure includes a conductor in contact with water, and the high-voltage generating water mist spraying structure includes a high-voltage circuit module, so that the conductor in contact with water can be applied with high voltage to make the sprayed water droplets discharge in an electric field environment, thereby forming negatively charged water mist, i.e., negative ion water mist.

[0031] It is understood that the water mist spraying structure can be various devices capable of spraying water mist, including but not limited to piezoelectric ceramic spray devices, venturi tube spray devices, high-pressure atomizing spray devices, and nano-spray devices. Among them, the piezoelectric ceramic spray device refers to a device that atomizes water droplets based on the high-frequency vibration of piezoelectric ceramic sheets. The venturi tube spray device refers to a device that produces water mist by accelerating the airflow carrying water molecules through the venturi tube. The high-pressure atomizing spray device refers to a device that produces water mist by vaporizing water under high pressure, such as 20-50MPa. The nano-spray device is internally provided with an ultrasonic vibration device, which is excited to generate high-frequency vibration, thereby breaking down water droplets into tiny droplets to produce water mist.

[0032] 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 that can contact water, and only needs to electrically connect the conductor to the high-voltage circuit module through a connecting wire to generate negative ion water mist based on the discharge at the tip of the water droplet.

[0033] In this embodiment of the present invention, the negative ion water mist excitation module takes a Venturi tube spray device as an example, which specifically includes an air pump device 10, a water supply device 20, an excitation needle 30, a high-voltage generating unit 40 and a spray pipe 50, wherein the air pump device 10 is used to generate a high-speed airflow and supply it to the spray pipe 50, the water supply device 20 is used to provide water to the spray pipe 50, the air pump device 10 and the water supply device 20 are connected to the spray pipe 50, so that the high-speed airflow and water can be mixed in the spray pipe 50, and the excitation needle 30 is arranged in the spray pipe 50 to adjust the mist outlet aperture of the spray pipe 50.

[0034] It is understandable that the negative ion water mist excitation module 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 purification equipment, fresh air systems, etc.

[0035] In the present invention, the spray pipe 50 includes a pipe body 51 and a nozzle 52 to form a spray channel 53 therein. The nozzle 52 is mounted on the pipe body 51 and has a spray port 521 and a spray cavity 522 with a diameter gradually decreasing toward the spray port. The pump device 10 and the water supply device 20 are connected to the pipe body 51 of the spray pipe 50 in a continuous communication.

[0036] The ignition needle 30 is disposed within the injection channel 53 of the tubular injection tube 50 and includes a guide body 31 and a needle body 32, wherein the guide body 31 and the needle body 32 are detachably connected. In the example illustrated in the figure, the guide body 31 is an expanded portion that is tapered and has a gradually decreasing diameter toward the injection port 521 of the nozzle 52, and the needle body 32 passes through the guide body 31. The guide body 31 is disposed at the position where the nozzle 52 and the tube body 51 are connected, and is configured so that when the position of the ignition needle 30 is adjusted, the gap between the guide body 31 and the tube body 51 or the nozzle 52 can be adjusted, thereby adjusting the size of the pore for mist output.

[0037] It is understandable that the needle in the existing water injection sprayer is used to adjust the size of the mist outlet aperture. In the present invention, the needle and the guide body in the traditional water injection sprayer are connected to high pressure to form the excitation needle 30 of the present invention.

[0038] The air pump device 10 is used to generate a high-speed airflow into the injection pipe 50. The water from the water supply device 20 also enters the injection pipe 50 and falls into the injection pipe 50 due to gravity. Therefore, because the inner diameter of the injection pipe 50 is extremely small, the high-speed airflow generated by the air pump device 10 is further accelerated in the injection pipe 50 and carries water droplets to be ejected outward at the injection port 521 of the nozzle 52 of the injection pipe 50 to generate water mist.

[0039] The air pump device 10 can be any compressed gas generating device, such as an electric air pump, a membrane air pump, a plunger air pump, a centrifugal air pump, etc. When the negative ion water mist excitation module is integrated into air conditioning equipment such as air conditioners, vehicle-mounted purification equipment, and fresh air systems, the negative ion water mist excitation module can also directly utilize the air pump system in the air conditioning equipment.

[0040] In this embodiment, the water from the water supply device 20 is shown to fall into the spray pipe 50 due to gravity. In other embodiments, the water from the water supply device 20 can also be pumped into the spray pipe 50 by other pumping devices.

[0041] In the present invention, the needle body 32 of the ignition needle 30 is a conductor electrically connected to the high-voltage generating unit 40, so that the needle body 32 of the ignition needle 30 is connected to the high voltage. This provides a voltage environment for the ignition needle 30, which discharges through the needle tip 321, further ionizing the outwardly ejected water droplets, thereby generating a negative ion water mist. It is understood that the water in the water supply device 20 can also be added with other ingredients such as perfume, freshener, etc., so that in addition to forming the negative ion water mist, it can also diffuse fragrance into the ambient air.

[0042] In the present invention, the needle body 32 is a conductor that can contact water. The high-voltage generating unit 40 includes a high-voltage circuit module 41 and a connecting wire 42. The needle body 32 is electrically connected to the high-voltage circuit module 42 through the connecting wire 42, so that it can conduct electricity in the high-voltage electric field environment of the high-voltage generating unit 40. In this way, a high-voltage electric field is applied to the sprayed water droplets in the spray tube 50 to ionize the sprayed water droplets.

[0043] 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 excitation module of the present invention directly electrically connects the high-voltage circuit module 42 to the conductive body 32 that can contact water, thereby ionizing the water droplets and generating negative ion water mist. Thus, the negative ion water mist excitation module of the present invention directly connects the needle 32 used to adjust the diverter 31 in the prior art to high voltage, thereby acting as an ionization needle. When the needle 32 applies high voltage to generate an electric field, the sprayed water droplets are directly ionized, thereby generating negative ion water mist.

[0044] The present invention integrates the high-voltage circuit module 41 with the needle body 32 through a connecting wire 42, so that the needle body 32 is ionized while generating water mist to obtain negative ion water mist. This is unlike the water negative ion injection structure in the prior art CN115986569A, which generates water mist that relies on the air negative ions ionized by the discharge needle independent of the water negative injection structure to increase the negative ion concentration.

[0045] In the present invention, the needle body 32 can have multiple functions. The high-speed airflow generated by the air pump device 10 carries the water droplets provided by the water supply device 20 and moves forward at high speed in the venturi ejector formed by the ejection pipe 50 to form atomized water droplets, and rubs with the conductive needle body 32 to produce water negative ion droplets. In other words, the needle body 32 is a conductor, which is made of a material that loses electrons more easily than water, so it is more likely to lose electrons when rubbing with tiny water droplets, thereby causing the tiny water droplets to be charged and produce negative ion droplets. In addition, because the needle body 32 is directly electrically connected to the high-voltage circuit module 41, an ionization tip is formed at its needle tip 321, thereby providing a high-voltage electric field environment at the nozzle 52, so that the negative ion droplets are further ionized by the high-voltage electric field, so that the negative ion water mist excitation module of the present invention can produce a high-concentration water negative ion mist.

[0046] It is understood that the high-voltage circuit module 41 can be a separate module or integrated into a control circuit board, so that the control circuit board can control the operation of the air pump device 10 and the high-voltage circuit module 41. In the present invention, the high-voltage circuit module 121 can provide a high voltage of -2kV to -20kV.

[0047] Accordingly, the present invention also provides a negative ion water mist excitation method, which includes a water mist injection step and a water mist ionization step. More specifically, in the water mist injection step, water mist is generated through an injection channel 53. In the water mist ionization step, a needle 32 disposed in the injection channel 53 is electrically connected to a high-voltage generating unit 40 to ionize the water mist, thereby generating negative ion water mist.

[0048] In this negative ion water mist excitation method, the needle body 32 is a conductor, and the needle tip 321 of the needle body 32 contacts the water mist at a position adjacent to the injection port 521 at the end of the injection channel 53. This generates water mist by mixing the jet airflow with the water and flowing through the injection channel 53. Furthermore, under high voltage conditions of -2kV to -20kV provided by a high voltage generator, the needle tip 321 ionizes the water mist in the injection channel 53, thereby generating a high-concentration water negative ion mist.
