Description

Technical Field

[0001] The invention relates to the field of negative ions, and in particular to a water negative ion air conditioner and a water negative ion generating device thereof for preventing needle fogging, so as to prevent water fog from gathering on a charging needle. Background Art

[0002] As people pay more attention to environmental air and healthy breathing, negative ion products have begun to appear on the market. Traditional negative ion generating equipment generally generates negative ions through corona discharge. Specifically, electrons are generated during the corona process. The oxygen molecules O2 in the air are more electrophilic than CO2, N2 and other molecules. Therefore, oxygen molecules will preferentially obtain electrons to form negative air ions. Because oxygen molecules account for a large proportion of negative air ions, they are often called negative oxygen ions in the air.

[0003] The inventor of this application proposes a method of combining corona discharge with water mist generation, charging the water mist through a corona device so that the water mist absorbs the negative ions generated by the corona discharge to obtain a high concentration of water negative ions. However, due to the electrostatic effect, the needle tip of the corona device will gather water droplets and cover the needle tip, making it impossible for the needle tip to discharge water droplets. In addition, the instantaneous speed of the water droplets sprayed by the water mist generating device will be greater than the wind speed at the high-voltage needle tip. This also makes it easier for the high-voltage needle tip to gather water droplets, making it impossible for the high-voltage needle tip to discharge.

[0004] Air conditioners are devices that regulate and control parameters such as the temperature, humidity, and flow rate of ambient air. However, existing air conditioners do not yet have the function of generating negative ions. Summary of the invention

[0010] Preferably, the needle mist shielding structure comprises a needle heating element, which is arranged on the charging needle for heating the charging needle, so that the water mist droplets attached to the charging needle are heated and vaporized.

[0011] Preferably, the needle mist shielding structure includes an air guide cavity and a heating ring, and the heating ring is arranged at the air outlet end of the air guide cavity, so that the water mist droplets reaching the heating ring are heated and vaporized to prevent the water mist generated by the water mist generating device from reaching the charging needle.

[0016] Preferably, the water mist generator further comprises a shell portion, wherein the shell portion has a communicating receiving groove and a guiding channel, wherein the liquid reaches the receiving groove from the liquid storage container via the guiding channel to be impacted by the mesh atomizing sheet to generate water negative ions.

[0039] like Figures 1 to 5 Shown is a water negative ion air conditioner 1000 and a water negative ion generating device 100 thereof according to an embodiment of the present invention. The water negative ion generating device 100 includes a water mist generating device 10, a high-voltage charging device 20 and an airflow driving device 30, wherein the water mist generating device 10, the high-voltage charging device 20 and the airflow driving device 30 can be assembled in a box, the water mist generating device 10 is used to generate water mist, the high-voltage charging device 30 charges the water mist generated by the water mist generating device 10 to generate water negative ions, and the airflow driving device 30 blows the water negative ions to the environment outside the box to increase the concentration of negative ions in the environment, thereby purifying the air and benefiting the health care of the human body.

[0040] The water negative ion air conditioner 1000 includes an air conditioner main body 100 and the water negative ion exciting device 100, and the water negative ion exciting device 100 is installed on the air conditioner main body 1001 to increase the function of providing water negative ions to the water negative ion air conditioner 1000. The air conditioner main body 1001 has the structure of a common air conditioner, which may include structures such as a box, a refrigeration system and / or a heating system, an air duct system, a humidification system, an electrical system, etc., so that the air conditioner can operate normally. It is understandable that the air conditioner main body 1001 can be a central air conditioner, an indoor wall-mounted air conditioner, a vertical air conditioner, a car air conditioner, etc.

[0041] The water negative ion generating device 100 can be used independently, or installed in other air conditioning equipment such as an air purifier, a fresh air system, etc.

[0042] More specifically, the water mist generating device 10 includes a liquid storage cavity 11 and one or more water mist generators 12, wherein the liquid storage cavity 11 is used to store liquid for the water mist generator 12 to generate water mist, and the liquid stored in the liquid storage cavity 11 can be various suitable liquid water, such as drinking pure water, drinking conductive negative ion liquid and drinking mineral water.

[0043] The water mist generator 12 is any device that can generate water mist from the liquid in the liquid storage chamber 11. For example, in one embodiment, it can be implemented as a venturi tube atomizer, which may include a contraction tube, a throat, a water spray device, and a diffusion tube, wherein the relative flow rate of the gas-liquid phase in the contraction tube and the throat is very large, and the droplets sprayed from the nozzle are further atomized into finer droplets under the impact of the high-speed airflow. In another embodiment, the water mist generator 12 may have a heating device for heating the liquid to generate water mist. Or in another embodiment, the water mist generator 12 may be an ultrasonic vibration atomizer, which breaks up the liquid water molecule structure through the high-frequency resonance of the ceramic atomizer to generate water mist.

[0044] exist Figures 1 to 5 and Figure 8 In the illustrated embodiment, the water mist generator 12 includes a mesh atomizer sheet 121 having a mesh area in the center, and the mesh atomizer sheet 121 is driven to vibrate at a high frequency to vibrate the liquid from the liquid storage chamber 11 at a high frequency to generate atomized droplets, which are further charged by the high-voltage charging device 30 to generate water negative ions. The mesh atomizer sheet 121 of the water mist generator 12 is electrically connected to an atomization control circuit 13, and the high-frequency vibration of the mesh atomizer sheet 121 is controlled by the atomization control circuit 13 under the condition that a power supply 14 provides power supply, for example, the mesh atomizer sheet 121 is loaded with a voltage with a frequency of 3K-5MHZ and a peak value of 60-90V through the atomization control circuit 13.

[0045] The high-voltage charging device 20 includes one or more charging needles 21, a boost circuit 22 and a needle mist shielding structure 23. The boost circuit 22 raises the voltage to above -4kV. The charging needle 21 is electrically connected to the boost circuit 22 to charge the water mist generated by the water mist generator 12, that is, the electrons generated by the charging needle 21 are promptly absorbed by the water mist generated by the water mist generator 13, thereby generating negative ion water mist rich in negative ions. The needle mist shielding structure 23 is used to prevent the water mist generated by the water mist generator 13 from adhering to and gathering on the charging needle 21, causing the charging needle 21 to be covered by the water mist and unable to charge the water mist generated by the water mist generator 12. The high-voltage charging device 20 can share the power supply 14 with the water mist generator 12, or can be configured with a power supply separately.

[0046] like Figure 3 and Figure 5 As shown in , the needle mist shielding structure 23 includes an air guide cavity 231, which is a wind speed increasing cavity, having an inner cavity 2310 and including an air inlet end 2311 and an air outlet end 2312. The charging needle 21 is installed in the air outlet end 2312 of the air guide cavity 231. Along the direction from the air inlet end 2311 to the air outlet end 2312, the inner diameter of the inner cavity 2310 of the air guide cavity 231 gradually decreases, for example Figure 4 As shown in the figure, the cross-section of the inner cavity 2310 is conical, so that when the airflow generated by the airflow pushing device 30 reaches the air outlet end 2312 from the air inlet end 2311 of the air guide cavity 231 of the needle mist shielding structure 23, the wind pressure and wind speed at the position of the charging needle 21 increase, so that the water mist generated by the water mist generator 12 is not easy to approach the charging needle 21, thereby playing a role in isolating the water mist.

[0047] That is to say, when the water mist generated by the water mist generator 12 reaches the position of the charging needle 21, it absorbs the negative ions generated by the ionization of the charging needle 21 and is blown to the outside of the water negative ion generating device 100 by the air flow discharged from the air outlet 2312 of the air guide cavity 231, so that it is not easy to gather on the charging needle 21.

[0048] The air guide cavity 231 further forms a groove 2313 at the position of the air outlet end 2312, and the charging needle 21 extends into the groove 2313, thereby forming a charging chamber in the groove 2313. The outer surface 2314 of the air outlet end 2312 of the air guide cavity 231 is used to block the water mist generated by the water mist generator 12 from entering the groove 2313, thereby preventing a large amount of water mist from directly reaching the charging needle 21 from the side of the charging needle 21.

[0049] like Figure 5 As shown in , the air guide cavity 231 is formed with a mounting wall 2315 at the air outlet end 2312, and the charging needle head 21 is mounted on the air outlet end 2312 of the air guide cavity 231 through the central position of the mounting wall 2315, so that the charging needle head 21 can be firmly assembled on the air outlet end 2312 of the air guide cavity 231. The mounting wall 2315 also has one or more through holes 2316, which connect the groove 2313 with the inner cavity 2310 of the air guide cavity 231, and the wind pressure increases when the airflow guided by the air guide cavity 231 reaches the through hole 2316, so that the airflow is blown out from the through hole at a higher speed, so that the water mist generated by the water mist generator 12 is not easy to approach the charging needle head 21.

[0050] like Figure 6 As shown in , according to another embodiment, the needle mist isolation structure 23 includes the air guide cavity 231 and a needle heating element 232, wherein the needle heating element 232 can be implemented as a component capable of heating the charging needle 21, for example, it can be an electric heating wire, a metal ceramic heating element, a heating film, etc. In this embodiment, the needle heating element 232 can be implemented as a heating resistance wire, which is sleeved on the charging needle 21 and connected to the controller and power supply of the water negative ion generating device 100, so that when the working voltage is input into the charging needle 21 and the water mist is charged, the needle heating element 232 is used to heat the charging needle 21 so that the charging needle 21 is in a heat preservation state, so that when the water mist generated by the water mist generator 12 reaches the charging needle 21, the charging needle 21 in a higher temperature state can heat and vaporize the water mist attached to the charging needle 21, thereby preventing the water mist from accumulating on the charging needle 21.

[0051] like Figure 7 As shown in , according to another embodiment, the needle mist-blocking structure 23 includes the air guide cavity 231 and a heating ring 233, wherein the heating ring 233 can be implemented as an electric heating wire, a metal ceramic heating element, a heating film, etc., such as an electric heating wire sleeved on the outer surface 2314 of the air outlet end 2312 of the air guide cavity 231, and electrically connected to the controller and power supply of the water negative ion generating device 100. The charging needle 21 is located in the heating ring 233, so that when the working voltage is input into the charging needle 21 to start charging the water mist, the heating ring 233 is used to prevent the water mist generated by the water mist generator 12 from approaching the charging needle 21.

[0052] More specifically, when the water mist generated by the water mist generator 12 reaches the heating ring 233 at the air outlet end 2312 of the air guide cavity 231, the heating ring 233 can heat and vaporize the water mist, thereby preventing the water mist from gathering on the charging needle 21. After the water mist absorbs negative ions near the charging needle 21, it is carried away by the airflow generated by the airflow pushing device 30.

[0053] Accordingly, in Figure 5 and Figure 6 In the example shown, the needle heating element 232 and the heating ring 233 may be configured with corresponding temperature detectors to facilitate the control of the needle heating element 232 and the heating ring 233 .

[0054] In the present invention, the mesh atomizing sheet 121 is driven by a voltage of a predetermined frequency and peak value to vibrate at a high frequency, and its center position 1210 is the center position for converting liquid into droplets, and a predetermined distance D needs to be maintained between it and the charging needle 21, so as to prevent the water mist droplets generated by the mesh atomizing sheet 121 from being attached to the charging needle 21 due to the distance being too close, and also to prevent an arc from occurring between the charging needle 21 and the mesh atomizing sheet 121, causing the charging needle 21 to discharge high voltage to the entire water negative ion generating device 100. The charging needle 21 is made of a corrosion-resistant material, preferably 316L stainless steel.

[0055] In the present invention, it is found according to experimental data that, preferably, the distance D between the position of the charging needle 21 and the center position 1210 of the water mist generator 12 of the water mist generating device 10 is as follows:

[0056] When the working voltage of the charging needle 21 is between -4kv and -6kv, the distance D between the position of the charging needle 21 and the center position 1210 of the water mist generator 12 of the water mist generating device 10 is greater than 10mm.

[0057] When the working voltage of the charging needle 21 is between -6kv and -8kv, the distance D between the position of the charging needle 21 and the center position 1210 of the water mist generator 12 of the water mist generating device 10 is greater than 15mm.

[0058] When the working voltage of the charging needle 21 is between -8kv and -11kv, the distance D between the position of the charging needle 21 and the center position 1210 of the water mist generator 12 of the water mist generating device 10 is greater than 20mm.

[0059] Preferably, for example in a specific example, the distance D between the position of the charging needle 21 and the center position 1210 of the water mist generating device 10 can be selected to be 30 mm, and the voltage of the charging needle 21 is preferably -10 kV.

[0060] like Figure 3 As shown in, in this embodiment of the present invention, the water negative ion generating device 100 includes a plurality of mesh atomizing sheets 121 arranged at intervals from each other, the charging needle 21 is located at the center of the six mesh atomizing sheets 121, and the distance D between the charging needle 21 and the center position 1210 of the six mesh atomizing sheets 121 is equal, for example, 30 mm. In this way, when the charging needle 21 ionizes and generates electrons, the six mesh atomizing sheets 121 located around it generate water mist and absorb the electrons generated by the ionization of the charging needle 21 located at the center thereof to form water negative ion mist.

[0061] In addition, the needle tip of the charging needle 21 may be coplanar with the mesh atomizer sheet 121 or may not be coplanar, and the charging needle 21 may be located near the front or rear of the mesh atomizer sheet 121. When the charging needle 21 is located behind the mesh atomizer sheet 121 along the direction of the airflow, the water mist generated by the mesh atomizer sheet 121 is more likely to adhere to the charging needle 21, so the present invention provides the needle mist isolation structure 23 to prevent water mist droplets from gathering on the charging needle 21.

[0062] It is understandable that these mesh atomizing sheets 121 can be driven to work at the same time, or they can work periodically in batches. Preferably, when these mesh atomizing sheets 121 are periodically started to work, at least one mesh atomizing sheet 121 around each charging needle 21 is in working state and produces water mist in the same time period to absorb the electrons ionized by the corresponding charging needle 21, thereby ensuring that the water negative ion generating device 100 can generate water negative ions when in working state, and preventing these mesh atomizing sheets 121 from being damaged easily due to continuous work.

[0063] It is understandable that in Figure 3 In the example shown, the center positions 1210 of the plurality of mesh atomizer sheets 121 around the charging needle head 21 are equal to the distance D therebetween. In another variant implementation, the center positions 1210 of the mesh atomizer sheets 121 may also be different from the positions of the corresponding charging needle heads 21, but the distance D satisfies that it is greater than 10 mm.

[0064] Those skilled in the art should understand that the arrangement of the charging needle 21 and the mesh atomizer sheet 121 of the water mist generator 12 can be changed according to design requirements, as long as the distance D between each charging needle 21 and the center position 1210 of the corresponding mesh atomizer sheet 121 meets the above conditions.

[0065] The airflow driving device 30 includes a driving fan 31 and one or more filters 32. The driving fan 31 rotates to generate airflow. The fan preferably adopts a turbine fan. The filter 32 is used to filter air, so that relatively clean air is sent to the water mist generating device 10 and the charging needle 21 of the high-voltage charging device 20 by the driving fan 31. More specifically, the box has an air inlet, wherein under the action of the driving fan 31, the air enters the box 40 from the air inlet of the box and is filtered by the filter 32, and then blows to the water mist generating device 10 and the charging needle 21 of the high-voltage charging device 20, so that the water mist of negative ions generated by the synergistic action of the water mist generating device 10 and the high-voltage charging device 20 is blown to the environment outside the box, so as to increase the migration distance of the water mist of negative ions.

[0066] In the present invention, preferably, the water mist generator 12 also generates negative ions, so that the water negative ion generating device of the present invention generates water mist with a relatively high concentration of water negative ions. The discharge needle ionizes to generate negative ions such as O2- negative molecules, which are absorbed by the water mist generated by the water mist generator 12 to generate O2- negative molecular clusters [O2-(H2O)n]. The mesh area of ​​the mesh atomizer sheet 121 of the water mist generator 12 is made of a material that is more likely to lose charge relative to the liquid and the pore size of its micropores is less than 10 microns, so that the diameter of the generated water mist droplets is less than 10 microns. Preferably, the micropore size of the mesh atomizer sheet 121 is less than 5 microns, so that the mesh atomizer sheet 121 vibrates at a high frequency to generate water mist, while the droplets and the mesh atomizer sheet 121 are rubbed at a high frequency to generate water negative ions such as H+ negative water molecular clusters [H302-(H2O)n], HO- negative water molecular clusters OH-(H2O)n, negative water molecules -(H2O)n and other water negative ions, so that the generated water negative ions are more beneficial to the recuperation and health care of the human body.

[0067] More specifically, when a voltage of a predetermined frequency such as 3kHZ-5MHZ and a predetermined peak value such as 60-90V is applied to the mesh atomization sheet 121, the mesh atomization sheet 121 will generate high-frequency vibrations to hit the water to cause the water to resonate and generate tiny droplets, and the tiny droplets will rub against the mesh atomization sheet 121 at a high frequency while being generated, so that the tiny droplets are further negatively charged to form water negative ions and diffuse from the mesh area in the center of the mesh atomization sheet 121 into the environment.

[0068] The water mist generator 12 further includes one or more housing parts 123, each of which has one or more receiving grooves 1231, one or more buffer channels 1232 and a guide channel 1233, wherein the guide channel 1233 is connected to the liquid storage cavity 20, wherein each of the receiving grooves 1231 is connected to the corresponding guide channel 1233, and the receiving groove 1231 extends transversely to the corresponding guide channel 1233. For example, in this embodiment, each of the guide channels 1233 is arranged in a vertical direction, and each of the receiving grooves 1231 is arranged in a horizontal direction, and the water at the bottommost mesh atomizing sheet 121 can be guided from the adjacent guide channel 1233. In this embodiment, the liquid naturally enters each of the guide channels 1233 from the liquid storage chamber 11 due to gravity and further flows into the buffer channel 133 to be buffered in the buffer channel 133, so that an appropriate amount of liquid reaches the receiving tank 1231 for the mesh atomization sheet 121 to impact the water in the receiving tank 1231 and efficiently generate water negative ions.

[0069] The shell portion 123 of the water mist generating device 10 is annular and has a gap 124 formed in the middle, wherein the wind generated by the propulsion fan 31 passes through the gap 124 to reach the water mist generating device 10 and the charging needle 21 of the high-voltage charging device 20 and carries the negative water ions forward to migrate and diffuse toward the front of the negative water ion generating device 100.
