[0047] As shown in Figures 1 to 9, a water negative ion generating device according to a preferred embodiment of the present invention includes a water negative ion emitting component 10, a circulating water supply system 20, a blowing component 30 and a housing 40, wherein the water negative ion emitting component 10, the circulating water supply system 20 and the blowing component 30 are installed in the housing 40, the circulating water supply system 20 is used to supply water to the water negative ion emitting component 10 so that when the water negative ion emitting component 10 is working, the water is subjected to high-frequency friction to generate water negative ions, and the blowing component 30 includes a filter and a fan, which is used to draw air into the water negative ion generating device and, after filtering, blow the water negative ions generated by the water negative ion emitting component 10 to the outside to carry the water negative ions to the environment. In the present invention, the circulating water supply system 20 is also used to recycle the condensed water generated by the water negative ion emitting component 10 in the process of generating water negative ions.

[0048] In the present invention, the circulating water supply system 20 includes a water supply chamber 21, a water storage chamber 22, a water pump 23, and a piping assembly 24. The water supply chamber 21 is located on the upper side of the housing 40, and the water storage chamber 22 is located on the lower side of the housing 40. The piping assembly 24 connects the water pump 23 between the water supply chamber 21 and the water storage chamber 22. In this embodiment, the water supply chamber 21 is used to supply water to the water negative ion emitting assembly 10, and the water storage chamber 22 is used to store condensed water generated during the operation of the water negative ion emitting assembly 10. The water pump 23 is used to pump the condensed water stored in the water storage chamber 22 into the water supply chamber 21, thereby serving as a portion of the water supply to the water negative ion emitting assembly 10. The piping assembly 24 includes a first connecting pipe 241 and a second connecting pipe 242. The first connecting pipe 241 connects between the water supply chamber 21 and the water pump 23, and the second connecting pipe 242 connects between the water pump 23 and the water storage chamber 22.

[0049] It is understood that in the present invention, the water supply cavity 21 and the water storage cavity 22 can be two independent water tanks, which are installed in the housing 40. In a modified embodiment, the water supply cavity 21 and the water storage cavity 22 can also be formed by a portion of the housing 40. In other words, the water supply cavity 21 and the water storage cavity 22 can be integrated into the housing 40, with the top of the housing 40 forming the water supply cavity 21 and the bottom forming the water storage cavity 22.

[0050] As shown in Figures 2, 3 and 6, the water negative ion emission assembly 10 is arranged between the water supply cavity 21 and the water storage cavity 22, and includes a water negative ion injection module 11, a controller 12, a water guide device 13, a buffer sleeve 14 and a power module 15, wherein the water guide device 13 is connected to the water supply cavity 21, and has a vertically arranged water guide channel 131 and a transversely arranged water storage channel 132, so that the water in the water supply cavity 21 in the circulating water supply system 20 can enter the water guide channel 131 and reach the water storage channel 132 by gravity, and the water negative ion injection module 11 is accommodated in the buffer sleeve 14 and installed on the water guide device 13, so that the water negative ion injection module 11 can be electrically connected to the controller 12 and driven under the power supply module 15. It can vibrate back and forth at high frequency so that the water entering the water storage channel 132 rubs against the water negative ion injection module 11 to generate charged tiny droplets to generate negative ion water mist.

[0051] In this embodiment, referring to Figures 7 to 9, the water negative ion spray module 11 includes an impact plate 111 and at least one piezoelectric plate 112 attached to and electrically connected to the impact plate 111, wherein the piezoelectric plate 112 and the impact plate 111 are electrically connected to the controller 12 and are powered and driven by the power supply. The piezoelectric plate 112 and the impact plate 111 can be electrically connected to the controller 12 via two wires 114, respectively. Alternatively, the piezoelectric plate 112 and the impact plate 111 can be insulated from the impact plate 111 and electrically connected to the controller 12 via two wires 114. More specifically, the impact plate 111 has a central region 1111 and an outer ring region, wherein the piezoelectric plate 112 is a piezoelectric ceramic and is annular, attached to the outer ring region of the impact plate 111, and the central region 1111 of the impact plate 111 has a plurality of micropores 1113 to form a mesh structure.

[0052] The impact plate 111 is used to vibrate and impact the water in the water storage channel 132, thereby generating negative ions. The corresponding buffer sleeve 14 is positioned in correspondence with the impact plate 111 so that when the impact plate 111 vibrates to generate negative water ions, it simultaneously impacts the buffer sleeve 14, thereby preventing the impact plate 111 from generating noise due to the impact of the water. More specifically, when a voltage of a predetermined frequency and peak value is applied to the piezoelectric plate 112 and the impact plate 111, the impact plate 111 generates high-frequency vibrations that strike the buffer sleeve 14, causing the water between the buffer sleeve 14 and the impact plate 111 to resonate and generate tiny droplets. As the tiny droplets are generated, they rub against the impact plate 111 at high frequency between the impact plate 111 and the buffer sleeve 14, further acquiring a negative charge and forming negative water ions. These ions then diffuse from the micropores 1113 into the environment. The blowing mechanism 30 blows air, carrying the negative water ions released from the micropores 1113 to the external environment, thereby increasing the migration distance of the negative water ions. In another example, the piezoelectric piece 112 may be connected to both positive and negative electrodes. When a voltage with a predetermined frequency and peak value is applied, the piezoelectric piece 112 vibrates, thereby driving the impact piece 111 to vibrate.

[0053] Correspondingly, when the impact piece 111 is driven by the piezoelectric piece 112 to vibrate back and forth, it simultaneously completes two processes to generate water negative ions, namely, vaporizing the water between the buffer sleeve 14 and the impact piece 111 and charging it, thereby efficiently generating water negative ions. In the present invention, when the water negative ion injection module 11 vibrates at a high frequency, the water molecules between the buffer sleeve 14 and the impact piece 11 are driven and resonate at the same frequency and vaporize to generate tiny droplets. At the same time, the generated tiny droplets rub against the high-frequency vibrating impact piece 111, causing the impact piece 111 to lose its charge and the tiny droplets to gain charge. The vaporized tiny droplets that have gained charge thus form water negative ions such as H+-containing negative water molecule clusters [H302-(H2O)n], HO--containing negative water molecule clusters OH-(H2O)n, and negative water molecules -(H2O)n.

[0054] In this embodiment, a buffer sleeve 14 is provided at the end of the water storage channel 132 facing the water negative ion injection module 11. The buffer sleeve 14 is made of an elastic material, such as elastic silicone or elastic rubber, and includes an annular fixing plate 141, a buffer body 142 and a connector 143. The buffer body 142 extends inwardly and integrally through the connector 143 to the annular fixing plate 141. The water negative ion injection module 11 is buried in the buffer sleeve 14. The position of the buffer body 142 corresponds to the central area 1111 of the impact plate 111 having multiple micropores 1113. In this way, when the impact plate 111 vibrates at high frequency, the central area 1111 having multiple micropores 1113 correspondingly impacts the buffer body 142, thereby buffering the vibration of the impact plate 111 and reducing the noise when hitting the water.

[0055] It is worth mentioning that the buffer body 142 is thinner than the annular fixing plate 141 and is located in the inner cavity 144 of the annular fixing plate 141 to form a central position of the annular fixing plate 141. The central area 1111 having multiple micropores 1113 is circular, and the buffer body 142 is also circular in shape. When the buffer body 142 is struck, it is confined in the inner cavity 144 and elastically vibrates to elastically cushion the central area 1111 of the impact plate 111, and at the same time allows the central area 1111 of the impact plate 111 to rub against water, thereby charging the tiny droplets and generating negative ion water mist.

[0056] As shown in Figures 2 and 3, in addition, the water negative ion emission component 10 of the water negative ion generating device of the present invention may also include a charging device 16, which is a high-voltage discharge module, and its driving voltage can be increased to preferably above -4kV to charge the water mist generated by the water negative ion injection module 11, that is, the electrons generated by the charging needle are promptly absorbed by the water mist generated by the water negative ion injection module 11, thereby generating negative ion water mist rich in negative ions.

[0057] The impact plate 111 of the water negative ion generating device charges the atomized droplets based on frictional charging. In this way, the negative charge generated by the charging device 16 is more easily adsorbed by the negative ion water mist, thereby increasing the concentration of negative charge adsorbed by the water ions and making it easier to saturate the water with negative charges. In other words, the water negative ion generating device of the present invention not only atomizes the droplets, but also makes the atomized water mist itself carry negative ions, thereby forming a negative ion water mist. In this way, the negative ion water molecules are more likely to adsorb the negative charge supplemented by the charging device. Therefore, compared with the charge of the atomized and uncharged droplets, the already charged negative ion water mist of the present invention is more easily supplemented with charge and charged to produce water negative ions with a higher negative ion concentration.

[0058] In the present invention, the charging device 16 is arranged between multiple water negative ion injection modules 11, so that the negative ion water mist generated by the multiple water negative ion injection modules 11 can be supplemented with charge to produce high-concentration water negative ions. Therefore, compared with the negative ion generating equipment in the prior art, the water negative ion generating equipment of the present invention can produce water negative ions with higher concentration.

[0059] It is understood that the circulating water supply system 20 of the present invention includes a water supply cavity 21 disposed at the top of the housing 40, a water storage cavity 22 disposed at the bottom of the housing 40, and a water pump 23 connected between the water supply cavity 21 and the water storage cavity 22 via a pipeline. The water supply cavity 21 is connected to the water guide 13, so that the water stored in the water supply cavity 21 can be supplied to the water guide 13. When the water negative ion injection module 11 installed in the water guide 13 vibrates, it causes the water to vibrate and rub against the water, thereby generating negative ion water mist. The water storage cavity 22 is used to store condensed water that condenses when the water negative ion injection module 11 generates negative ion water mist. That is to say, the condensed water in the air will adhere to the inside of the box body 40 and further fall into the water storage cavity 22 and be collected by the water storage cavity 22. When the water pump 23 is working, it can pump the water stored in the water storage cavity 22 into the water supply cavity 21, thereby serving as part of the water source supplied to the water guide device 13, so that the condensed water can be recycled and the risk of excessive condensed water accumulating in the equipment and causing a circuit short circuit can be avoided.

[0060] The circulating water supply system 20 of the present invention also includes a water shortage level detector 25 arranged in the water supply cavity 21. The water shortage level detector 25 is installed at the bottom or lower middle position of the water supply cavity 21. The first water pipe interface 2411 of the first connecting pipe 241 is located at the top or upper middle position of the water supply cavity 21, and its position is higher than the water shortage level detector 25.

[0061] The circulating water supply system 20 further includes a water level detector 26 disposed in the water storage chamber 22. The water level detector 26 is mounted at the top or upper middle portion of the water storage chamber 22. The second water pipe interface 2421 of the second connecting pipe 242 is located at the bottom or lower middle portion of the water storage chamber 22.

[0062] The water storage cavity 22 includes a water storage cavity body 221 and a top cover 222, wherein the top cover 222 is disposed on the top side of the water storage cavity body 221 to form a water storage chamber 223 between the water storage cavity body 221 and the top cover 222. The water storage cavity 22 also has a groove 224 formed on the upper side of the top cover 222, and a water inlet 225 is provided in the center of the top cover 222. In this way, condensed water generated by the water negative ion generating device during operation can easily drip into the groove 224 and be collected. It then enters the water storage chamber 223 through the water inlet 225 of the top cover 222 and is stored in the water storage cavity 22. When the water pump 23 is in operation, it is pumped into the water supply cavity 21. In this embodiment, the water storage cavity 22 is used to collect condensed water, and the water supply cavity 21 is used as the main water storage tank and the water supply tank for the water negative ion injection module 11.

[0063] In addition, in this embodiment, the water negative ion emission assembly 10 further includes a water guide wall 17, which surrounds the water guide device 13 and protrudes from the water negative ion injection module 11. The water guide wall 17 forms a water guide surface 171 on the inner side between the housing 40 and the water negative ion injection module 11. The water guide surface 171 can be an arcuate surface or an inclined surface. The bottom side of the water guide wall 17 forms a bottom opening 172, the position of which corresponds to the groove 224 of the water storage chamber 22. Thus, when the water negative ion injection module 11 is operating and generates condensed water, the condensed water adheres to the water guide surface 171 of the water guide wall 17 and falls from the bottom opening 172 into the groove 224 of the water storage chamber. Furthermore, the condensed water falls through the water inlet 225 into the water storage chamber 223 of the water storage chamber 22, thereby being collected and stored in the water storage chamber 22.

[0064] In this embodiment of the present invention, the controller 13 of the water negative ion generating device can serve as the control center of the entire arrangement, and is communicatively connected to the water pump 23, the water shortage level detector 25, and the water storage level detector 26 to control the operation of the water pump 23. In another variant embodiment, the water pump 23 is communicatively connected to the water shortage level detector 25 and the water storage level detector 26, and the water pump 23 is configured with a separate control module to control the operation of the water pump 23.

[0065] In this embodiment of the present invention, the impact plate 111 of the water negative ion generating device charges the atomized droplets based on frictional charging. The negative charge generated by the charging device 16 supplements the charge of the negative ion water mist generated by the impact plate 111, thereby generating a high concentration of water negative ions. In the process of generating water negative ions, some water droplets will form condensed water after meeting each other. In one control strategy, when the water level detector 26 of the water storage cavity 22 detects the presence of water, the controller 13 of the water negative ion generating device controls the water pump 23 to start, pumping water in the water storage chamber 223 of the water storage cavity 22 into the supply cavity 21, wherein the water pump 23 stops working after a predetermined working time. The predetermined working time can be measured and calculated based on the volume of the water storage cavity 22 and the working power of the water pump 23.

[0066] Furthermore, when the water level detector 25 in the water supply chamber 21 detects a water shortage in the water supply chamber 21, the controller 13 of the water negative ion generating device can initiate a water shortage alarm. This alarm can include emitting an audible alarm or generating a light alarm. Preferably, when the water negative ion generating device initiates the water shortage alarm, the controller 13 activates the water pump 23 to pump water from the water storage chamber 223 of the water storage chamber 22 into the supply chamber 21, and the water pump 23 stops operating after a predetermined period of time.

[0067] As shown in FIG10 , according to a first variant of the preferred embodiment of the present invention, a circulating water supply system 20 includes a water supply chamber 21, a water storage chamber 22, a water pump 23, and a piping assembly 24. The water supply chamber 21 is disposed on the upper side of a housing 40, the water storage chamber 22 is disposed on the lower side of the housing 40, and the piping assembly 24 is used to connect the water pump 23 between the water supply chamber 21 and the water storage chamber 22. In this embodiment, the circulating water supply system 20 further includes a water shortage level detector 25 disposed in the water supply chamber 21. The water shortage level detector 25 is mounted at the bottom or lower middle portion of the water supply chamber 21. The circulating water supply system 20 also includes a water storage level detector 26 and a drainage water level detector 27 arranged in the water storage cavity 22. The water storage level detector 26 is installed at the top or upper middle position of the water storage cavity 22, and the drainage water level detector 27 is installed at the bottom or lower middle position of the water storage cavity 22. The drainage water level detector 27 is correspondingly located on the lower side of the water storage level detector 26.

[0068] In the circulating water supply control method of the water negative ion generating device of this embodiment of the present invention, when the water level detector 26 of the water storage cavity 22 detects the presence of water, the water pump 23 starts to start and pumps the water in the water storage chamber 223 of the water storage cavity 22 into the supply cavity 21. When the water level detector 26 and the drainage water level detector 27 detect that there is no water at the corresponding positions, the water pump 23 stops working.

[0069] Furthermore, when the water level detector 25 in the water supply chamber 21 detects a water shortage in the water supply chamber 21, the controller 13 of the water negative ion generating device can initiate a water shortage alarm. This alarm can include emitting an audible alarm or generating a light alarm. Preferably, when the water negative ion generating device initiates a water shortage alarm, the controller 13 activates the water pump 23 to pump water from the water storage chamber 223 of the water storage chamber 22 into the supply chamber 21. When the water level detector 27 detects that there is no water at the corresponding location, the water pump 23 stops.

[0070] As shown in FIG11 , according to a second variant of the preferred embodiment of the present invention, the circulating water supply system 20 of the present invention includes a water supply chamber 21, a water storage chamber 22, a water pump 23, and a piping assembly 24, wherein the water supply chamber 21 is disposed on the upper side of a housing 40, the water storage chamber 22 is disposed on the lower side of the housing 40, and the piping assembly 24 is used to connect the water pump 23 between the water supply chamber 21 and the water storage chamber 22. In this embodiment, the water supply chamber 21 is used to supply water to the water negative ion emitting assembly 10 and serves as the main water storage tank, the water storage chamber 22 is used to store condensed water generated during the operation of the water negative ion emitting assembly 10, and the water pump 23 is used to pump the reserve water and condensed water stored in the water storage chamber 22 into the water supply chamber 21, thereby serving as a portion of the water source supplied to the water negative ion emitting assembly 10. In this embodiment, the circulating water supply system 20 further includes a water supply level detector 28 disposed in the water supply cavity 21. The water supply level detector 28 is mounted at the top or upper middle portion of the water supply cavity 21. The circulating water supply system 20 further includes a water shortage level detector 25 disposed in the water supply cavity 21.

The water storage level detector 26 is mounted at the top or upper middle portion of the water storage cavity 22, and the drainage level detector 27 is mounted at the bottom or lower middle portion of the water storage cavity 22. The drainage level detector 27 is correspondingly positioned below the water storage level detector 26.

[0071] In the circulating water supply control method of the water negative ion generating device of this embodiment of the present invention, when the water shortage water level detector 25 in the water supply cavity 21 detects that there is no water at its corresponding position and the drainage water level detector 27 in the water storage cavity 22 detects that there is water at its corresponding position, the water pump 23 is turned on to pump the water in the water storage cavity 22 into the water supply cavity 21 until the water supply level detector 28 detects that there is water at its corresponding position or the drainage water level detector 27 detects that there is no water at its corresponding position, and then the water pump 23 is stopped.

[0072] In another control mode, when the water level detector 26 in the water storage chamber 22 detects that there is water at its corresponding position, the water pump 23 starts to start to pump the water in the water storage chamber 22 into the water supply chamber 21 until the water supply level detector 28 detects that there is water at its corresponding position or the drainage level detector 27 detects that there is no water at its corresponding position, and then the water pump 23 stops working.

[0073] In addition, when the water shortage level detector 25 detects that the corresponding position has been short of water for a considerable predetermined time, the negative ion generating device will alarm, for example, the predetermined time is 10 seconds, thereby reminding the user that the water in the water storage chamber 22 is not enough to be pumped into the upper water supply chamber 21. The user will manually add water to the water supply chamber 21 when the system alarms.

[0074] As shown in Figure 12, according to the third variant embodiment of the above-mentioned preferred embodiment of the present invention, the circulating water supply system 20 of the present invention includes a water supply cavity 21, a water storage cavity 22, a water pump 23 and a pipeline assembly 24, wherein the water supply cavity 21 is arranged on the upper side of the box body 40, the water storage cavity 22 is arranged on the lower side of the box body 40, and the pipeline assembly 24 is used to connect the water pump 23 between the water supply cavity 21 and the water storage cavity 22. In this embodiment, the water supply chamber 21 is used to supply water to the water negative ion emitting assembly 10, and the water storage chamber 22 serves as a water tank primarily for storing water. That is, during use of the water negative ion generating device, a user can add water to the water storage chamber 22 to store water therein for standby use. Furthermore, the water storage chamber 22 stores condensed water generated during the operation of the water negative ion emitting assembly 10. The water pump 23 is used to pump the standby water and condensed water stored in the water storage chamber 22 into the water supply chamber 21, thereby serving as a water source for supplying the water negative ion emitting assembly 10. The pipeline assembly 24 includes a first connecting pipeline 241 and a second connecting pipeline 242, wherein the first connecting pipeline 241 is connected between the water supply chamber 21 and the water pump 23, and the second connecting pipeline 242 is connected between the water pump 23 and the water storage chamber 22. The first water pipe interface 2411 of the first connecting pipe 241 is located at the top or upper middle of the water supply cavity 21 , and the second water pipe interface 2421 of the second connecting pipe 242 is located at the bottom or lower part of the water storage cavity 22 .

[0075] In this embodiment, the circulating water supply system 20 further includes a water level detector 28 disposed in the water supply cavity 21, and the water level detector 28 is installed at the top or upper middle portion of the water supply cavity 21. The circulating water supply system 20 further includes a water level detector 26 disposed in the water storage cavity 22, and the water level detector 26 is installed at the top or upper middle portion of the water storage cavity 22.

[0076] In the water circulation control method of the water negative ion generating device of this embodiment of the present invention, when the water level detector 26 in the water storage cavity 22 detects that there is no water at the corresponding position, the water negative ion generating device performs an alarm operation.

[0077] When the water supply level detector 28 in the water supply cavity 21 detects that there is no water at the corresponding position, the water pump 23 is started and starts working to pump the water in the water storage cavity 22 into the water supply cavity 21 until the water supply level detector 28 detects that there is water at the corresponding position, and the water pump 23 stops working.

[0078] As shown in Figure 13, according to the fourth variant embodiment of the above-mentioned preferred embodiment of the present invention, the circulating water supply system 20 of the present invention includes a water supply cavity 21, a water storage cavity 22, a water pump 23 and a pipeline assembly 24, wherein the water supply cavity 21 is arranged on the upper side of the box body 40, the water storage cavity 22 is arranged on the lower side of the box body 40, and the pipeline assembly 24 is used to connect the water pump 23 between the water supply cavity 21 and the water storage cavity 22. In this embodiment, the water supply chamber 21 is used to supply water to the water negative ion emitting component 10, and the water storage chamber 22 serves as a water tank, which is mainly used to store water. That is to say, during the use of the water negative ion generating device, the user can add water to the water storage chamber 22 to store water in the water storage chamber 22 for standby use. Furthermore, the water storage chamber 22 stores condensed water formed during the operation of the water negative ion emitting component 10, and the water pump 23 is used to pump the standby water and condensed water stored in the water storage chamber 22 into the water supply chamber 21, thereby serving as a water source supplied to the water negative ion emitting component 10. In this embodiment, the circulating water supply system 20 further includes a water supply level detector 28 disposed in the water supply cavity 21, which is mounted at the top or upper middle portion of the water supply cavity 21. The circulating water supply system 20 further includes a water shortage level detector 25 disposed in the water supply cavity 21, which is mounted at the bottom or lower middle portion of the water supply cavity 21. The water shortage level detector 25 is positioned below the water supply level detector 28. The circulating water supply system 20 further includes a water storage level detector 26 disposed in the water storage cavity 22, which is mounted at the top or upper middle portion of the water storage cavity 22.

[0079] In this embodiment, when the water shortage level detector 25 in the water supply cavity 21 detects that there is no water at the corresponding position, the water pump 23 starts to start and pumps the water in the water storage cavity 22 into the water supply cavity 21 until the water supply level detector 28 detects that there is water at its corresponding position.

[0080] As shown in Figures 14 to 16, it is a structural schematic diagram of a water negative ion generating device 500 provided in an embodiment of the present application. The water negative ion generating device 500 includes a water mist excitation device 501, which is used to rub water through a friction plate to generate negative ion water mist; a water supply system 502, which is connected to the water mist excitation device 501 and is used to supply water to the water mist excitation device 501; and an ionization needle device 503, which is used to generate electrons through ionization to increase the concentration of negative ions.

[0081] The structure of the water mist excitation device 501 can refer to patent documents CN116336584A, CN116207618A, CN116053936A and CN115986569A. It is preferably based on the structure of a piezoelectric ceramic plate and a vibration plate, and the vibration plate with micropores is excited to produce high-frequency vibration to produce tiny droplets, and the tiny droplets are rubbed with water at high frequency through the vibration plate while being produced, so that the tiny droplets are further negatively charged to form negative ion water mist, and the negative ion water mist contains water negative ions such as H+-containing negative water molecule clusters [H302-(H2O)n], HO--containing negative water molecule clusters OH-(H2O)n, negative water molecules -(H2O)n, etc.

[0082] The ionization needle of the ionization needle device 503 is a slender conductive metal needle, typically made of materials such as tungsten and zirconium. The ionization needle device 503 uses the discharge of the ionization needle to knock electrons out of air molecules, thereby ionizing them. The water mist produced by the water mist excitation device 501 can absorb negative ions, such as O2-negative molecules, produced by the electrons ionized by the ionization needle device 503. These negative ion mists are then absorbed by the water mist excitation device 501, producing O2-negative molecule clusters [O2-(H2O)n]. This, in turn, allows more negative ions to attach to the negative ion mist, effectively increasing the negative ion concentration.

[0083] The present invention provides a method for controlling a water negative ion generating device 500, comprising the following steps:

[0084] S201: Obtaining the water shortage status of the water supply system 502;

[0085] S202: issuing a control instruction according to the water shortage state of the water supply system 502 to control the water mist excitation device 501 and the ionization needle device 503 to operate or stop operating.

[0086] The above method provided in the embodiment of the present application can control the water mist excitation device 501 and the ionization needle device 503 to run or stop running according to the water shortage state. When there is water in the water tank, the water mist excitation device 501 and the ionization needle device 503 are controlled to run at the same time. Not only does it rely on the negative ion water generated by the water mist excitation device 501, but it also increases the negative ion content in the negative ion water mist through the ionization needle device 503. At the same time, the water mist excitation device 501 and the ionization needle device 503 are controlled to run or stop running according to the water shortage state. Compared with the situation in the prior art that negative ions cannot be provided as long as there is a water shortage, negative ions can continue to be generated when water mist is not generated, which alleviates the problem of a sharp drop in negative ion concentration to a certain extent.

[0087] The water supply system 502 of the water negative ion generating device 500 includes an upper water tank 5021 and a lower water tank 5022. The upper water tank 5021 is connected to the water mist excitation device 501 and is used to supply water to the water mist excitation device 501; the lower water tank 5022 is installed below the upper water tank 5021 and the water mist excitation device 501 and is used to collect condensed water generated during the negative ion water mist generation process.

[0088] Another control method for a water negative ion generating device 500 provided in an embodiment of the present application includes the following steps:

[0089] S401: Obtaining the water shortage status of the water supply system 502;

[0090] S402: Determine whether there is water in the upper water tank 5021;

[0091] S403: In the presence of water, controlling the water mist excitation device 501 and the ionization needle device 503 to operate;

[0092] S404: Otherwise, determine whether there is water in the lower water tank 5022;

[0093] S405: If there is water in the lower water tank 5022, control the lower water tank 5022 to supply water to the upper water tank 5021;

[0094] S406: Otherwise, when both the upper water tank 5021 and the lower water tank 5022 are short of water, the water mist excitation device 501 is controlled to stop running, while the ionization needle device 503 is kept running.

[0095] A water pump 1023 is installed between the upper water tank 5021 and the lower water tank 5022. Once it detects that the upper water tank 5021 is short of water but the lower water tank 5022 is full of water, the water pump 1023 is activated to pump the water from the lower water tank 5022 into the upper water tank 5021. Only when both the upper and lower water tanks are short of water, and the mist activating device 501 continues to generate mist, is the mist activating device 501 turned off, while the ionizing needle device 503 remains on to generate negative ions. This alleviates the problem of a sharp drop in negative ion concentration caused by water shortage.

[0096] Correspondingly, water level detectors can be set in the upper water tank 5021 and the lower water tank 5022, respectively, which are installed at the bottom or lower middle position of the upper water tank 5021 and the lower water tank 5022, respectively, to detect and help determine whether the upper water tank 5021 and the lower water tank 5022 are in a water shortage state.

[0097] It is understandable that users have different needs for negative ions. When the negative ion concentration demand is not high, the water mist excitation device 501 can be controlled to continue working, while the ionization needle device 503 can be controlled to stop working. In some possible implementations, the ionization needle device 503 is controlled to stop working when any of the following conditions are met:

[0098] (1) The concentration of negative ions in the air is higher than the preset concentration;

[0099] (2) Low negative ion mode in response to user settings;

[0100] (3) The humidity in the air is higher than the preset humidity;

[0101] (4) The current time is within the preset negative ion off time period.

[0102] A negative ion concentration detection device can be set on the water negative ion generating device 500 to determine whether the negative ion concentration in the air has reached a preset requirement based on the detection result. Once the preset requirement is reached, the ionization needle device 503 can be turned off.

[0103] Furthermore, a user-selectable mode can be set on the water negative ion generating device 500. The user can decide whether to use the high negative ion mode or the low negative ion mode. Once the user selects the low negative ion mode, the ionization needle device 503 is also turned off. When the ionization needle device 503 is turned off, the water mist excitation device 501 can be kept running to generate negative ion water mist with a lower concentration of negative ions.

[0104] Furthermore, in some time periods, such as at night, too many negative ions are not needed. Therefore, a negative ion off time period can be set, and the ionization needle device 503 is automatically turned off during this time period.

[0105] In this way, when a high concentration of negative ions is not needed or the negative ion concentration has reached the required level, the ionization needle device 503 can be turned off, thereby saving energy and extending the service life of the ionization needle device 503.

[0106] In some examples, the negative water ion generating device 500 further includes a refrigeration device 504, and the negative water ion generating device further includes a fan 505 for blowing the water mist generated by the water mist excitation device 501 out of the negative water ion generating device 500. The refrigeration device 504 is installed between the fan 505 and the ionization needle device 503 or on the inlet side of the fan 505. Referring to FIG15 , the refrigeration device 504 is schematically installed between the fan 505 and the ionization needle device 503. The fan 505 can blow the water mist generated by the water mist excitation device 501 out of the negative water ion generating device 100, and the refrigeration device 504 is arranged between the fan 505 and the ionization needle device 503 as a water mist generating device, thereby increasing the humidity of the air in the air duct, so that the water mist molecules capture the electrons released by the ionization needle device 503 and generate more negative water ions, thereby improving the working efficiency of the negative water ion generating device 500.

[0107] Furthermore, the refrigeration device 504 is a semiconductor refrigeration device. For example, it can be a semiconductor refrigeration chip. Since the semiconductor refrigeration chip is small, low-noise, and low-power, it does not increase the size of the water negative ion generating device 500, and can effectively improve the concentration and efficiency of negative ion generation.

[0108] It is understandable that when both the upper water tank 5021 and the lower water tank 5022 are short of water, the water mist excitation device 501 has to stop working. At this time, when only the ionization needle device 503 is turned on, the ionization needle device 503 can generate negative oxygen ions. However, these negative oxygen ions have no carrier in the air, which causes the negative oxygen ions generated by the ionization needle device 503 to react with positive ions in the environment upon entering the environment, and cannot migrate to a long distance in the environment, thus failing to achieve the ideal purification effect on the environment and the health-promoting effect on the human body.

[0109] In the present invention, when the water mist excitation device 501 stops running, the refrigeration device 504 is turned on. In this way, when the fan 505 is working, the humidity of the air reaching the ionization needle device 503 will increase, thereby generating water mist molecules in the air. These water mist molecules migrate in the water negative ion generating device 500, and they themselves can also generate a certain amount of negative ions through friction, that is, the water mist molecules will be charged. In this way, the negative charge generated by the ionization needle device 503 is more easily adsorbed on the already charged negative ion water mist, thereby making the negative charge concentration of the water ions adsorbed higher.

[0110] That is to say, after the water mist excitation device 501 stops running, although there is no water mist excitation device 501 to generate negative ion water mist, by turning on the refrigeration device 504 to cool and humidify the wind sent by the fan 505, water mist molecules with a small amount of charge can be generated. This negative ion water mist with a small amount of negative charge can also capture the electrons released by the ionization needle device 503 to produce more water mist with a higher concentration of negative ions, so that these negative ions can attach to the water mist and migrate to a farther distance in the environment along with the wind generated by the fan 505.

[0111] Another control method provided in an embodiment of the present application includes the following steps:

[0112] S501: Obtaining the water shortage status of the water supply system 502;

[0113] S502: Determine whether the water supply system 502 is short of water; if so, execute steps S503-S504; otherwise, execute step S505;

[0114] S503: When the water supply system 502 is short of water, the water mist excitation device 501 is controlled to stop operating, while the ionization needle device 503 is kept operating;

[0115] S504: Control the operation of the refrigeration device 504;

[0116] S505: Control the water mist excitation device 501 to operate, and control the ionization needle device 503 to operate.

[0117] In the above embodiment, once the water mist excitation device 501 is stopped and the ionization needle device 503 is kept running, the number of water mist molecules is small, so the refrigeration device 504 is turned on to increase the humidity of the air or the air in the air duct to generate more water negative ions.

[0118] In some examples, the determination of whether to automatically activate the refrigeration device 504 can be made by obtaining the concentration of negative air ions. Specifically, the concentration of negative air ions can be first obtained, and if the concentration of negative air ions is lower than a preset concentration, the refrigeration device 504 can be controlled to operate. On the other hand, if the concentration of negative ions in the air is higher than the preset concentration, indicating that the negative ion concentration meets the needs of the environment and the human body, the refrigeration device 504 can be temporarily shut down to save energy, relying solely on the negative ions generated by the water mist excitation device 501 or the ionization needle device 503. This can effectively improve the efficiency and quantity of negative ion generation, thereby enhancing the working performance of the water negative ion generating device 500.

[0119] As shown in Figures 17 to 20, a water negative ion generating device includes a water negative ion emitting assembly 610, a circulating water supply system 620, a blowing assembly 630, and a housing 640. The water negative ion emitting assembly 610, the circulating water supply system 620, and the blowing assembly 630 are installed in the housing 640. The circulating water supply system 620 is used to supply water to the water negative ion emitting assembly 610 so that when the water negative ion emitting assembly 610 is working, the water is subjected to high-frequency friction to generate water negative ions. The blowing assembly 630 includes a filter and a fan, which is used to draw air into the water negative ion generating equipment and, after filtering, blow the water negative ions generated by the water negative ion emitting assembly 610 to the outside to carry the water negative ions to the environment. In the present invention, the circulating water supply system 620 is also used to recycle the condensed water generated by the water negative ion emitting assembly 610 during the water negative ion generation process.

[0120] The water negative ion emission component 610 includes a water negative ion injection module 611, a controller 612 and a water guide device 613, wherein the water guide device 613 is connected to the water supply cavity 621, so that the water in the water supply cavity 621 in the circulating water supply system 620 can enter the water negative ion injection module 611 by gravity, so that the water negative ion injection module 611 can be electrically connected to the controller 612 and can vibrate back and forth at a high frequency when driven, so that the water and the water negative ion injection module 611 rub against each other to generate charged tiny droplets to generate negative ion water mist.

[0121] The structure of the negative water ion emission assembly 610 can be found in patent documents CN116336584A, CN116207618A, CN116053936A, and CN115986569A. It is preferably based on a piezoelectric ceramic plate and a vibrating plate structure. The vibrating plate with micropores is excited to generate high-frequency vibrations to produce tiny droplets. As the tiny droplets are generated, the vibrating plate rubs against water at high frequencies, thereby further carrying a negative charge on the tiny droplets and forming a negative ion mist. The negative water ion emission assembly 610 may also include an ionization unit to supplement the negative ion mist generated by the vibrating plate with charge to further produce a high concentration of negative water ions. The aforementioned patent applications are incorporated herein by reference.

[0122] In this embodiment of the present invention, the circulating water supply system 620 includes a water supply chamber 621, a water storage chamber 622, a water pump 623, and a piping assembly 624. The water supply chamber 621 is disposed on the upper side of the housing 640, the water storage chamber 622 is disposed on the lower side of the housing 640, and the piping assembly 624 is used to connect the water pump 623 between the water supply chamber 621 and the water storage chamber 622. In this embodiment, the water supply chamber 621 is used to supply water to the water negative ion emitting assembly 610, the water storage chamber 622 is used to store condensed water formed during the operation of the water negative ion emitting assembly 610, and the water pump 623 is used to pump the condensed water stored in the water storage chamber 622 into the water supply chamber 621, thereby serving as a portion of the water source supplied to the water negative ion emitting assembly 610. The pipeline assembly 624 includes a first connecting pipeline 6241 and a second connecting pipeline 6242 , wherein the first connecting pipeline 6241 is connected between the water supply cavity 621 and the water pump 623 , and the second connecting pipeline 6242 is connected between the water pump 623 and the water storage cavity 622 .

[0123] It is understood that in the present invention, the water supply cavity 621 and the water storage cavity 622 can be two independent water tanks mounted on the housing 640. In a modified embodiment, the water supply cavity 621 and the water storage cavity 622 can also be formed by a portion of the housing 640. In other words, the water supply cavity 621 and the water storage cavity 622 can be integrally integrated into the housing 640, with the water supply cavity 621 formed at the top and the water storage cavity 622 formed at the bottom.

[0124] The negative water ion generating device further includes a water quality detection device 626, which is installed between the water supply chamber 621 and the water storage chamber 622, and is located in the first connecting pipe 6241 or the second connecting pipe 6242. The water quality detection device 626 is used to detect the water quality between the water supply chamber 621 and the water pump 623. The water pump 623 stops operating if the water quality does not meet preset conditions. The water quality detection device 626 can be a water quality detector, a water quality sensor, etc.

[0125] The above-mentioned device provided by the embodiment of the present invention is provided with a water quality detection device 626 between the water supply cavity 621 and the water storage cavity 622, that is, the water quality of the water flowing from the water storage cavity 622 to the water supply cavity 621 is detected, and the water quality index can be obtained before the water flows into the water supply cavity 621. Once the water quality is unqualified, such as too many impurities, or contains harmful substances, the water pump is controlled to stop working to prevent water with unqualified water quality from continuing to flow into the water supply cavity, that is, before the water flows into the water supply cavity 621, cut-off measures are taken, thereby effectively ensuring that the water in the water supply cavity is always water of qualified water quality, thereby ensuring the safety of the water negative ion generating device.

[0126] Furthermore, the water pump 623 in the water negative ion generating device provided in the embodiment of the present application is a non-leak-proof water pump, that is, a water pump that does not include a leak-proof device or a check valve, and the water pump 623 is located above the water storage cavity 622. In this way, after the water pump 623 stops working, since the water storage cavity 622 is located below the water pump 623, the water between the water supply cavity 621 and the water storage cavity 622 will flow back to the water storage cavity 622 located below due to gravity, so as to facilitate the subsequent further discharge and treatment of unqualified water.

[0127] As a preferred embodiment, the water quality detection device 626 is installed between the water pump 623 and the water storage chamber 622. That is, after the water is pumped out of the water storage chamber 622 by the water pump, if there are impurities or harmful substances in the pipeline causing the water quality to be unqualified, it can be detected in time by the water quality detection device 626, and an alarm can be issued in time and / or the water pump 623 can be controlled to stop working, so as to prevent the water with unqualified water quality from moving further upward and contaminating the water pipe between the water pump 623 and the water supply chamber 621.

[0128] As another embodiment, the water quality detection device 626 can also be installed between the water pump 623 and the water supply cavity 621. In this way, water quality detection can be performed before the water is pumped into the water supply cavity 621 to prevent water with unqualified water quality from flowing into the water supply cavity.

[0129] It is understandable that the number of water quality detection devices can be one, installed between the water pump and the water storage cavity. The number of water quality detection devices can also be multiple, such as two, three or more. The embodiment of the present application does not specifically limit the number of water quality detection devices. As an example, there can be two water quality detection devices, one water quality detection device is installed between the water pump 623 and the water supply cavity 621, and the other water quality detection device is installed between the water storage cavity 622 and the water pump 623. In this way, if a substance that may affect the water quality appears in a section of water pipe directly connected to the water supply cavity, it can be accurately detected by the water quality detection device, thereby ensuring that the water quality in the entire pipeline from the water storage cavity to the water supply cavity is qualified, further ensuring the safety and reliability of the water negative ion generating equipment.
