Description

Technical Field

[0001] This invention relates to the field of negative ion technology, and in particular to a water negative ion generating device and a circulating water supply control method thereof. Background Technology

[0002] The inventors of this application disclosed a water negative ion excitation device in Chinese patent application with publication number CN116336584A, which includes an excitation mechanism, a liquid storage chamber, and a blower mechanism. The liquid storage chamber is used to store water, and after water is injected into the liquid storage chamber through its water inlet, water is supplied to the excitation mechanism so that the water generates water negative ions when the excitation mechanism is working. The blower mechanism blows the water negative ions generated by the excitation mechanism to the outside of the water negative ion excitation device so that the water negative ions migrate and diffuse into the environment.

[0003] During the operation of the aforementioned water negative ion excitation device to generate water negative ions, condensation will form inside the device. Therefore, the housing of the water negative ion excitation device forms a storage tank below the excitation mechanism. The excitation mechanism also includes a recovery liquid excitation unit and a recovery liquid elastic absorbent. When there is water in the storage tank, the water will seep into the recovery liquid elastic absorbent. The recovery liquid excitation unit acts on the side of the recovery liquid elastic absorbent to generate water negative ions.

[0004] However, the elastic absorbent for recycling liquid is usually made of cotton swabs, which have a limited lifespan. During the absorption process, tiny air bubbles can enter the cotton swab. When the air bubbles accumulate to a certain extent, the elastic absorbent for recycling liquid will become clogged and lose its function of recycling condensate. Summary of the Invention

[0049] like Figures 1 to 9 The diagram illustrates a water negative ion generating device according to a preferred embodiment of the present invention. It includes a water negative ion emitting component 10, a circulating water supply system 20, a blower assembly 30, and a housing 40. The water negative ion emitting component 10, the circulating water supply system 20, and the blower assembly 30 are installed in the housing 40. The circulating water supply system 20 supplies water to the water negative ion emitting component 10, causing the water to generate water negative ions through high-frequency friction when the component operates. The blower assembly 30 includes a filter and a fan, which draws air into the water negative ion generating device and, after filtration, blows the water negative ions generated by the emitting component 10 to the outside to carry them into the environment. In this invention, the circulating water supply system 20 is also used to recycle and reuse the condensate generated by the water negative ion emitting component 10 during the generation of water negative ions.

[0050] In this 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 supplies water to the water negative ion emitting component 10, the water storage chamber 22 stores the condensate formed during the operation of the water negative ion emitting component 10, and the water pump 23 pumps the condensate stored in the water storage chamber 22 into the water supply chamber 21, thereby serving as part of the water source supplied to the water negative ion emitting component 10. The piping assembly 24 includes a first connecting pipe 241 and a second connecting pipe 242, wherein the first connecting pipe 241 connects the water supply chamber 21 and the water pump 23, and the second connecting pipe 242 connects the water pump 23 and the water storage chamber 22.

[0051] It is understood that in this invention, the water supply chamber 21 and the water storage chamber 22 can be two independent water tanks installed in the housing 40. In a modified embodiment, the water supply chamber 21 and the water storage chamber 22 can also be formed from a portion of the housing 40. That is, the water supply chamber 21 and the water storage chamber 22 can be integrally integrated into the housing 40, with the water supply chamber 21 formed at the top and the water storage chamber 22 formed at the bottom of the housing 40.

[0052] like Figure 2 , Figure 3 and Figure 6 As shown, the water negative ion emission assembly 10 is disposed between the water supply chamber 21 and the water storage chamber 22. It includes a water negative ion injection module 11, a controller 12, a water guiding device 13, a buffer sleeve 14, and a power module 15. The water guiding device 13 is connected to the water supply chamber 21 and has a vertically arranged water guiding channel 131 and a horizontally arranged water storage channel 132. In this way, water in the water supply chamber 21 of the circulating water supply system 20 can enter through gravity, reach the water guiding channel 131, and reach the water storage channel 132. The water negative ion injection module 11 is housed in the buffer sleeve 14 and installed on the water guiding device 13 so that the water negative ion injection module 11 can vibrate at a high frequency when it is electrically connected to the controller 12 and driven by the power supply module 15. This causes the water entering the water storage channel 132 to rub against the water negative ion injection module 11, thereby generating charged micro-droplets to produce negative ion water mist.

[0053] In this embodiment, reference Figures 7 to 9 As shown, the water negative ion jet module 11 includes an impact plate 111 and at least one piezoelectric sheet 112 attached to and electrically connected to the impact plate 111. The piezoelectric sheet 112 and the impact plate 111 are electrically connected to the controller 12 and powered and driven by the power source. The piezoelectric sheet 112 and the impact plate 111 can be electrically connected to the controller 12 via two wires 114, or the piezoelectric sheet 112 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. The piezoelectric sheet 112 is a piezoelectric ceramic and is ring-shaped, attached to the outer ring region of the impact plate 111. The central region 1111 of the impact plate 111 has multiple micropores 1113 to form a mesh-like structure.

[0054] The impact plate 111 is used to vibrate and impact the water in the water storage channel 132, thereby generating negative ions. A corresponding buffer sleeve 14 is fitted to the impact plate 111 so that when the impact plate 111 vibrates to generate negative water ions, it simultaneously impacts the buffer sleeve 14, thus preventing noise from the impact plate 111 impacting 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. Simultaneously, these tiny droplets rub against the impact plate 111 at high frequency between the impact plate 111 and the buffer sleeve 14, further acquiring a negative charge to form negative water ions, which then diffuse from the micropores 1113 into the environment. The blower mechanism 30 blows air, carrying the negative water ions released from the micropores 1113, to diffuse into the external environment, increasing the migration distance of the negative water ions. Alternatively, in another example, the piezoelectric element 112 may be connected to both positive and negative electrodes simultaneously. When a voltage of a predetermined frequency and peak value is applied, the piezoelectric element 112 vibrates, thereby driving the impact piece 111 to vibrate.

[0055] Correspondingly, when the impact plate 111 is driven by the piezoelectric plate 112 to reciprocate, it simultaneously completes two processes to generate water negative ions: that is, the water between the buffer sleeve 14 and the impact plate 111 is vaporized and charged, thereby efficiently generating water negative ions. In this invention, when the water negative ion injection module 11 vibrates at high frequency, the water molecules between the buffer sleeve 14 and the impact plate 11 are driven to 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 plate 111, causing the impact plate 111 to lose its charge and the tiny droplets to gain a charge. Thus, the vaporized tiny droplets that have gained a charge form water negative ions such as H+ negative water molecule clusters [H3O2-(H2O)n], HO- negative water molecule clusters OH-(H2O)n, negative water molecules -(H2O)n, etc.

[0056] In this embodiment, a buffer sleeve 14 is provided at the end of the water storage channel 132 facing the water negative ion jet 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 connecting body 143. The buffer body 142 extends inwardly from the annular fixing plate 141 through the connecting body 143. The water negative ion jet module 11 is embedded in the buffer sleeve 14. The position of the buffer body 142 corresponds to the central region 1111 of the impact plate 111, which has multiple micropores 1113. When the impact plate 111 vibrates at high frequency, the central region 1111 with multiple micropores 1113 impacts the buffer body 142, thereby buffering the vibration of the impact plate 111 and reducing the noise when hitting the water.

[0057] 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, forming a central position in the annular fixing plate 141. The central region 1111 with multiple micropores 1113 is circular, and the buffer body 142 is also correspondingly circular. When the buffer body 142 is impacted, it is confined within the inner cavity 144 to elastically vibrate, providing elastic cushioning to the central region 1111 of the impact plate 111, while simultaneously allowing the central region 1111 of the impact plate 111 to rub against water, thereby charging the tiny droplets and generating negative ion water mist.

[0058] like Figure 2 and Figure 3 As shown in the figure, 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. The charging device 16 is a high-voltage discharge module, whose driving voltage can be raised to preferably above -4kV, so as to charge the water mist generated by the water negative ion spray module 11. That is, the electrons generated by the charging needle are absorbed by the water mist generated by the water negative ion spray module 11 in a timely manner, thereby generating negative ion water mist rich in negative ions.

[0059] The impact plate 111 of the water negative ion generating device charges the atomized droplets through triboelectric charging. This makes it easier for the negative charge generated by the charging device 16 to adsorb onto the negative ion water mist, resulting in a higher concentration of negative charge adsorbed by the water ions and easier saturation. In other words, the water negative ion generating device of this invention not only atomizes the droplets but also makes the atomized water mist itself carry negative ions, thus forming a negative ion water mist. This makes it easier for the negative ion water molecules to adsorb the negative charge supplemented by the charging device. Therefore, compared to simply atomizing uncharged droplets being charged, the already charged negative ion water mist of this invention is more easily charged to produce a higher concentration of negative ions.

[0060] In this invention, the charging device 16 is arranged between multiple water negative ion spraying modules 11, so that the negative ion water mist generated by the multiple water negative ion spraying modules 11 can be charged to generate a high concentration of water negative ions. Therefore, compared with the negative ion generating devices of the prior art, the water negative ion generating device of this invention can generate a higher concentration of water negative ions.

[0061] It is understood that the circulating water supply system 20 of the present invention includes a water supply chamber 21 disposed at the top of the tank 40, a water storage chamber 22 disposed at the bottom of the tank 40, and a water pump 23 connected between the water supply chamber 21 and the water storage chamber 22 via a pipeline. The water supply chamber 21 is connected to the water guiding device 13, so that the water stored in the water supply chamber 21 can be supplied to the water guiding device 13, thereby causing the water negative ion jet module 11 installed on the water guiding device 13 to vibrate and rub against the water to generate negative ion water mist when vibrating. The water storage chamber 22 is used to store the condensate that will form when the water negative ion jet module 11 generates negative ion water mist. In other words, condensation in the air will adhere to the inside of the housing 40 and fall into the water storage chamber 22 for collection. When the water pump 23 is working, it can pump the water stored in the water storage chamber 22 into the water supply chamber 21, thus serving as part of the water source supplied to the water guiding device 13. This allows for the recycling of condensate and avoids the risk of short circuits caused by excessive condensate accumulation in the equipment.

[0062] The circulating water supply system 20 of the present invention also includes a water shortage level detector 25 disposed in the water supply cavity 21. The water shortage level detector 25 is installed at the bottom or lower middle part 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 part of the water supply cavity 21, which is higher than the water shortage level detector 25.

[0063] The circulating water supply system 20 also includes a water level detector 26 installed in the water storage chamber 22, which is located at the top or upper middle part 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 part of the water storage chamber 22.

[0064] The water storage chamber 22 includes a main body 221 and a top cover 222, wherein the top cover 222 is disposed on the top side of the main body 221 to form a water storage chamber 223 between the main body 221 and the top cover 222. A groove 224 is also formed on the upper side of the top cover 222, and a water inlet 225 is located in the center of the top cover 222. This allows condensate generated during the operation of the negative ion generator to easily drip into the groove 224, be collected, and further enter the water storage chamber 223 from the water inlet 225 of the top cover 222 for storage in the water storage chamber 22. When the water pump 23 operates, the condensate is pumped into the water supply chamber 21. In this embodiment, the water storage chamber 22 is used to collect condensate, and the water supply chamber 21 serves as the main water storage tank and the water supply tank for the negative ion jet module 11.

[0065] In this embodiment, the water negative ion emitting component 10 also includes a water-guiding wall 17, which surrounds the water guiding device 13 and protrudes from the water negative ion jet module 11. The water-guiding wall 17 forms a water-guiding surface 171 on the inner side between the housing 40 and the water negative ion jet module 11, which can be an arc-shaped surface or a slope. A bottom opening 172 is formed on the bottom side of the water-guiding wall 17, corresponding to the groove 224 of the water storage cavity 22. Thus, when the water negative ion jet module 11 generates condensate, the condensate adheres to the water-guiding surface 171 of the water-guiding wall 17 and falls from its bottom opening 172 into the groove 224 of the water storage cavity. Furthermore, it falls through the inlet 225 into the water storage chamber 223 of the water storage cavity 22, where it is collected and stored.

[0066] In this embodiment of the invention, the controller 13 of the water negative ion generating device can serve as the control center of the entire setup. It 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 modified 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 equipped with a separate control module to control its operation.

[0067] In this embodiment of the invention, the impact plate 111 of the water negative ion generating device charges the atomized droplets through triboelectric charging. The negative charge generated by the charging device 16 replenishes the charge of the negative ion water mist generated by the impact plate 111, thereby generating a high concentration of water negative ions. During the generation of water negative ions, some water droplets will condense after encountering each other. In one control strategy, when the water level detector 26 of the water storage chamber 22 detects water, the controller 13 of the water negative ion generating device controls the water pump 23 to start, pumping the water in the water storage chamber 223 of the water storage chamber 22 into the supply chamber 21. The water pump 23 stops working after a predetermined working time, which can be measured and calculated based on the volume of the water storage chamber 22 and the working power of the water pump 23.

[0068] Additionally, when the water level detector 25 in the water supply chamber 21 detects a water shortage, the controller 13 of the negative ion generator can perform a water shortage alarm operation. This alarm operation can include emitting an alarm sound or generating an alarm light effect. Preferably, when the negative ion generator performs a water shortage alarm operation, the controller 13 controls the water pump 23 to start, pumping 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 working time.

[0069] like Figure 10As shown in the diagram, according to a first modified embodiment 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.

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 being installed at the bottom or lower middle position of the water supply chamber 21. The circulating water supply system 20 also includes a water level detector 26 and a drainage level detector 27 installed in the water storage cavity 22. The water level detector 26 is installed at the top or upper middle part of the water storage cavity 22, and the drainage level detector 27 is installed at the bottom or lower middle part of the water storage cavity 22. The drainage level detector 27 is correspondingly located below the water level detector 26.

[0070] In the circulating water supply control method of the water negative ion generating device in this embodiment of the present invention, when the water level detector 26 of the water storage chamber 22 detects water, the water pump 23 starts to pump the water in the water storage chamber 223 of the water storage chamber 22 into the supply chamber 21. When the water level detector 26 and the drainage level detector 27 detect that there is no water at the corresponding position, the water pump 23 stops working.

[0071] Additionally, when the water level detector 25 in the water supply chamber 21 detects a water shortage, the controller 13 of the negative ion generator can perform a water shortage alarm operation. This alarm operation can include emitting an alarm sound or generating an alarm light effect. Preferably, when the negative ion generator performs a water shortage alarm operation, the controller 13 controls the water pump 23 to start, pumping water from the water storage chamber 223 of the water storage chamber 22 into the supply chamber 21. The water pump 23 stops operating when the drainage level detector 27 detects that there is no water at the corresponding position.

[0072] like Figure 11As shown in the second modified embodiment 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 pipeline assembly 24. The water supply chamber 21 is disposed on the upper side of the tank 40, the water storage chamber 22 is disposed on the lower side of the tank 40, and the pipeline 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 supplies water to the water negative ion emitting component 10 and serves as the main water storage tank. The water storage chamber 22 stores the condensate formed during the operation of the water negative ion emitting component 10. The water pump 23 pumps the spare water stored in the water storage chamber 22 and the condensate into the water supply chamber 21, thereby serving as part of the 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. The water supply level detector 28 is installed at the top or upper middle position of the water supply cavity 21.

[0074] In another control mode, when the water level detector 26 in the water storage chamber 22 detects water at its corresponding position, the water pump 23 starts to pump water from the water storage chamber 22 into the water supply chamber 21. The operation of the water pump 23 stops when the water supply level detector 28 detects water at its corresponding position or the drainage level detector 27 detects no water at its corresponding position.

[0075] In addition, when the water level detector 25 detects that its corresponding position is continuously short of water for a considerable period of time, the negative ion generating device will sound an alarm, for example, the predetermined time is 10 seconds, thereby reminding the user that the water pumped from the water storage chamber 22 into the water supply chamber 21 is not enough to pump a sufficient amount of water into the water supply chamber 21, so that the user will manually add water to the water supply chamber 21 when the system alarms.

Furthermore, the water storage chamber 22 stores condensate formed during the operation of the negative ion emission component 10. The water pump 23 pumps the stored water and condensate from the water storage chamber 22 into the water supply chamber 21, thus providing a water source for the negative ion emission component 10. The pipeline assembly 24 includes a first connecting pipe 241 and a second connecting pipe 242, wherein the first connecting pipe 241 connects the water supply chamber 21 and the water pump 23, and the second connecting pipe 242 connects the water pump 23 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 component 10, and the water storage chamber 22 serves as a water tank, mainly used to store water. That is, 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 later use. Furthermore, the water storage chamber 22 stores the condensate formed during the operation of the water negative ion emitting component 10. The water pump 23 is used to pump the spare water and condensate stored in the water storage chamber 22 into the water supply chamber 21, thereby serving as the water source supplied to the water negative ion emitting component 10.
