[0003] In the existing water negative ion generating equipment, when the water negative ion emitting component is working, condensed water will be generated inside the equipment, and the condensed water needs to be recycled and reused to generate negative ion water mist. However, the recycled condensed water will pass through multiple components such as the water negative ion emitting component, the water storage cavity, and the water pipe. If there are residual minerals and tiny impurities in these components, especially the water pipe, these impurities will be deposited on the inner wall of the water pipe, affecting the purity of the water quality and causing the water quality to be unqualified. After such unqualified water is injected into the water tank, the water quality is unqualified and cannot be used to generate water negative ions.

[0020] like Figures 1 to 4The device is a water negative ion generating device, including 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, water is rubbed by high frequency to generate water negative ions, and the blowing component 30 includes a filter and a fan, which is used to inhale air into the water negative ion generating device, and after filtering, the water negative ions generated by the water negative ion emitting component 10 are blown 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.

[0021] The water negative ion emission component 10 includes a water negative ion injection module 11, a controller 12 and a water guide device 13, wherein the water guide device 13 is connected to the water supply cavity 21, so that the water in the water supply cavity 21 in the circulating water supply system 20 can enter the water negative ion injection module 11 by gravity, so that the water negative ion injection module 11 can be electrically connected to the controller 12 and can vibrate reciprocatingly at a high frequency when driven, so that the water and the water negative ion injection module 11 rub against each other to generate charged tiny droplets to generate negative ion water mist.

[0022] The structure of the water negative ion emission component 10 can refer to patent documents CN116336584A, CN116207618A, CN116053936A and CN115986569A, which are preferably based on the structure of piezoelectric ceramic sheets and vibrating sheets, and the vibrating sheets with micropores are excited to produce high-frequency vibrations to produce tiny droplets, and the tiny droplets are rubbed with water at high frequency through the vibrating sheets while being produced, so that the tiny droplets are further negatively charged to form negative ion water mist. The water negative ion emission component 10 may also include an ionization unit to supplement the negative ion water mist generated by the vibrating sheets to further produce high-concentration water negative ions, and the above patent applications are incorporated into this application by reference.

[0023] In the embodiment of the present invention, the circulating water supply system 20 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 housing 40, the water storage cavity 22 is arranged on the lower side of the housing 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 cavity 21 is used to supply water to the water negative ion emission assembly 10, the water storage cavity 22 is used to store condensed water formed during the operation of the water negative ion emission assembly 10, and the water pump 23 is used to pump the condensed water stored in the water storage cavity 22 into the water supply cavity 21, thereby serving as a part of the water source supplied to the water negative ion emission 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 cavity 21 and the water pump 23, and the second connecting pipeline 242 is connected between the water pump 23 and the water storage cavity 22.

[0024] It can be 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 box body 40. In a modified embodiment, the water supply cavity 21 and the water storage cavity 22 can also be formed by a part of the box body 40. That is, the water supply cavity 21 and the water storage cavity 22 can be integrated into the box body 40, and the top of the box body 40 forms the water supply cavity 21, and the bottom forms the water storage cavity 22.

[0025] like Figure 3 FIG. 1 is a schematic diagram of a water negative ion generating device provided by an embodiment of the present invention. The water negative ion generating device is Figures 1 to 4 On the basis of the invention, it also includes a water quality detection device 26, which is installed between the water supply cavity 21 and the water storage cavity 22, and is located in the first connecting pipeline 241 or the second connecting pipeline 242; the water quality detection device 26 is used to detect the water quality of the water between the water supply cavity 21 and the water pump 23, and the water pump 23 stops working when the water quality does not meet the preset conditions. The water quality detection device 26 can be a water quality detector, a water quality sensor, etc.

[0026] The above-mentioned device provided by the embodiment of the present invention is provided with a water quality detection device 26 between the water supply cavity 21 and the water storage cavity 22, that is, the water quality of the water flowing from the water storage cavity 22 to the water supply cavity 21 is detected, and the water quality index can be obtained before the water flows into the water supply cavity 21. Once the water quality is unqualified, such as too many impurities, or contains harmful substances, etc., the water pump is controlled to stop working to prevent the 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 21, the interception 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.

[0027] Further, the water pump 23 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 Figure 4 As shown, the water pump 23 is located above the water storage cavity 22. In this way, after the water pump 23 stops working, since the water storage cavity 22 is located below the water pump 23, the water between the water supply cavity 21 and the water storage cavity 22 will flow back to the water storage cavity 22 located below due to gravity, so as to facilitate the subsequent further discharge and treatment of unqualified water.

[0028] As a preferred embodiment, the water quality detection device 26 is installed between the water pump 23 and the water storage chamber 22. That is, after the water is pumped out of the water storage chamber 22 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 26, and an alarm can be issued and / or the water pump 23 can be controlled to stop working in time to prevent the water with unqualified water quality from moving further upward and contaminating the water pipe between the water pump 23 and the water supply chamber 21.

[0029] As another example, Figure 4 As shown, the water quality detection device 26 can also be installed between the water pump 23 and the water supply cavity 21, so that the water quality can be detected before the water is pumped into the water supply cavity 21 to prevent water with unqualified water quality from flowing into the water supply cavity.

[0030] It is understandable that the number of water quality detection devices can be one, installed between the water pump and the water storage chamber. 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, Figure 7 As shown, there can be two water quality detection devices, one water quality detection device 261 is installed between the water pump 23 and the water supply cavity 21, and the other water quality detection device 262 is installed between the water storage cavity 22 and the water pump 23. In this way, if a substance that may affect the water quality appears in a section of the 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 device.

[0031] like Figure 8 As shown, another water negative ion generating device provided in an embodiment of the present application is provided. In this embodiment, a water supply level detector 211 is further provided in the water supply cavity 21, and the water supply level detector 211 is installed at the top or the upper middle position of the water supply cavity 21. A water storage level detector 221 is further provided in the water storage cavity 22, and the water storage level detector 221 is installed at the top or the upper middle position of the water storage cavity 22.

[0032] In specific implementation, when the water level detector 221 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. When the water supply level detector 211 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 211 detects that there is water at the corresponding position, and the water pump 23 stops working.

[0033] like Fig. 9 As shown, another water negative ion generating device provided in an embodiment of the present application, in this embodiment, 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, wherein the water supply cavity 21 is arranged on the upper side of the box body 40, and the water storage cavity 22 is arranged on the lower side of the box body 40, and the pipeline assembly 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 cavity 21 is used to supply water to the water negative ion emitting component 10, and the water storage cavity 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 cavity 22 so that the water is stored in the water storage cavity 22 for standby use, and further, the water storage cavity 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 cavity 22 into the water supply cavity 21, thereby serving as a water source supplied to the water negative ion emitting component 10. In this embodiment, a water supply level detector 211 is also provided in the water supply cavity 21, and the water supply level detector 211 is installed at the top or the upper middle position of the water supply cavity 21. Furthermore, a water shortage level detector 212 is also provided in the water supply cavity 21, and the water shortage level detector 212 is installed at the bottom or the lower middle position of the water supply cavity 21, and the water shortage level detector 212 is located below the water supply level detector 211. A water storage level detector 222 is also provided in the water storage cavity 22, and the water storage level detector 222 is installed at the top or the upper middle position of the water storage cavity 22. In the specific implementation process, 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 212 into the water supply cavity 21 until the water supply level detector 28 detects that there is water at its corresponding position.

[0034] like Fig.10As shown, a water quality detection method applied to a water negative ion generating device provided in an embodiment of the present application, wherein the water negative ion generating device comprises a water storage cavity 22, a water supply cavity 21, a water pump 23 and a water quality detection device 26; the position of the water storage cavity 22 is lower than the water supply cavity 21; the water pump 23 and the water quality detection device 26 are both installed between the water supply cavity 21 and the water storage cavity 22; the method comprises the following steps: S801: Detecting water quality indicators of water between the water supply cavity 21 and the water storage cavity 22; S802: When the water quality index is greater than a preset threshold, an alarm signal is issued.

[0035] The alarm signal may be an alarm sound emitted by a speaker, a flashing light, or an alarm message displayed on a display interface, etc.

[0036] In the above-mentioned water quality detection method, the water quality indicator is the total dissolved solids TDS value. Total dissolved solids (TDS), also known as the total amount of dissolved solids, is measured in milligrams per liter (mg / L), which indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. The higher the TDS value, the more dissolved substances are contained in the water. The TDS value of purified water is usually between 0 and 9, the TDS value of mountain spring water is usually between 10 and 60, the TDS value of mineralized water is usually between 10 and 60, and the TDS value of ordinary tap water is usually between 100 and 300. By detecting the TDS value in water, the water quality can be effectively judged.

[0037] As an example, the TDS value can be used as a water quality indicator. At this time, the preset threshold can be set to any value between 0 and 100, such as 60. Of course, this embodiment does not limit the specific setting of the preset threshold.

[0038] The above-mentioned water quality detection method provided in the embodiment of the present application obtains the water quality of the water between the water supply cavity 21 and the water storage cavity 22 through the water quality detection device, and compares the water quality index with the preset threshold value. When the water quality index is greater than the preset threshold value, it means that the water quality is unqualified and cannot be used as a water source for generating water negative ions. At this time, an alarm measure is taken, such as turning on an alarm indicator light and / or an alarm prompt sound, to remind the user to take timely action, effectively ensuring the safety and reliability of the water negative ion generating device.

[0039] like Fig.11 As shown, another water quality detection method for water negative ion generating equipment provided in an embodiment of the present application comprises the following steps: S901: Detecting water quality indicators of water between the water supply cavity 21 and the water storage cavity 22; S902: When the water quality index is greater than a preset threshold, an alarm signal is issued and the water pump 23 is controlled to stop working.

[0040] In this embodiment, when the water quality index is greater than a preset threshold, the water pump is controlled to stop working, that is, water with unqualified water quality is no longer delivered to the water supply cavity 21, thereby preventing the water negative ion generating device from generating water negative ions based on the unqualified water in the water supply cavity 21, causing harm to the human body.

[0041] like Fig.12 As shown, another water quality detection method for a water negative ion generating device provided in an embodiment of the present application comprises the following steps: S1001: Detecting water quality indicators of water between the water supply cavity 21 and the water storage cavity 22; S1002: When the water quality index is greater than a first preset threshold and less than a second preset threshold, an alarm signal is issued; S1003: When the water quality index is greater than the second preset threshold, the water pump 23 is controlled to stop working.

[0042] In this embodiment, by setting two preset thresholds, the water quality is graded and controlled. If the water quality is not good but will not cause harm to the human body, the user can be reminded to perform corresponding inspections or repairs. Once the water quality index reaches the second preset threshold, the water pump is controlled to stop working to prevent the generated water negative ions from causing harm to the human body.

[0043] like Fig.13 As shown, another water quality detection method for a water negative ion generating device provided in an embodiment of the present application comprises the following steps: S1101: Detecting water quality indicators of water between the water supply cavity 21 and the water storage cavity 22; S1102: When the water quality index is greater than a preset threshold, the water pump 23 is controlled to stop working, and the water storage chamber 22 is controlled to open the water drain valve.

[0044] In this embodiment, the water storage chamber 22 includes a drain valve, which can be located below the water storage chamber 22. Once the drain valve is stuck, the water in the water storage chamber 22 will be directly drained, that is, the unqualified water will be drained, so that the unqualified water will no longer participate in the circulation of the water negative ion generating device, further ensuring the safety and reliability of the water negative ion generating device.
