Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning and negative ion health care, more particularly to a water negative ion generating device and a control method thereof. BACKGROUND

[0002] Negative ions can help sleep. On the one hand, negative ions can affect the function of the central nervous system, promote the balance of serotonin in the body, and serotonin is a neurotransmitter that can regulate mood and sleep. By increasing the level of serotonin, negative ions can help relax the nerves and relieve anxiety, thereby promoting deeper and more stable sleep. On the other hand, negative ions can neutralize positive ions in the air and combine with pollutants such as dust, pollen, and bacteria in the air, causing them to settle, thereby purifying the air and creating a cleaner sleep environment. This clean air environment helps improve respiratory function, reduces snoring and other problems, and improves sleep quality. Thirdly, negative ions can also help increase the oxygen content in the blood and promote oxygen supply to the brain. Adequate oxygen helps the brain relax and reduces fatigue, making it easier for people to fall asleep.

[0003] CN118293518A discloses a water negative ion generating module based on water mist charging, which includes a negative ion water mist excitation device and a charging device. The negative ion water mist excitation device includes a liquid storage cavity and a negative ion water mist excitation device. The negative ion water mist excitation device includes a mesh excitation sheet driven to vibrate, which generates negative ion water mist based on tribocharging by vibrating and rubbing the liquid from the liquid storage cavity. The charging device is used to charge the negative ion water mist generated by the negative ion water mist excitation device to generate high-concentration negative ion water negative ions. However, when the negative ion water mist excitation device generates negative ion water mist, condensate will be generated on the device, and excessive accumulation of condensate will affect the normal operation of the machine.

[0004] The negative ion water mist excitation device needs continuous water supply through the liquid storage cavity when it is working normally. When the liquid storage cavity is out of water, the water negative ion generating module will stop working, thereby stopping the generation of water negative ions. However, people often forget to add water to the liquid storage cavity when using the water negative ion machine.

[0005] In a typical application scenario, when using the water negative ion machine at night, people will not get up in the middle of the night to add water to the water negative ion machine, so when the water tank of the water negative ion machine runs out in the middle of the night, the machine will stop working. Since people usually do not add water in the middle of the night, this means that the machine may not be able to run continuously at night, resulting in interruption of negative ion release, thereby failing to exert its sleep aid effect. For people who may rely excessively on the sleep aid effect of the water negative ion machine, once the machine stops working due to lack of water, the user may feel uneasy or affect the quality of sleep, thereby producing a sense of dependence and psychological discomfort.

[0039] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0040] like Figure 1 、 Figure 3 as well as Figures 6 to 8 As shown, it is a structural schematic diagram of a water negative ion generating device 100 provided in an embodiment of the present application. The water negative ion generating device 100 includes a water mist excitation device 101, which is used to rub water through a friction plate to generate negative ion water mist; a water supply system 102, which is connected to the water mist excitation device 101 and is used to supply water to the water mist excitation device 101; and an ionization needle device 103, which is used to generate electrons through ionization to increase the concentration of negative ions.

[0041] The structure of the water mist excitation device 101 can refer to patent documents CN116336584A, CN116207618A, CN116053936A and CN115986569A, which are preferably based on the structure of piezoelectric ceramic sheets and vibrating sheets. The vibrating sheets with micropores are excited to produce high-frequency vibrations to generate tiny droplets. The tiny droplets are rubbed with water at high frequency at the same time through the vibrating sheets, so that the tiny droplets further carry negative charges to form negative ion water mist containing water negative ions such as H+ containing negative water molecule groups [H302-(H2O)n], HO- containing negative water molecule groups OH-(H2O)n, negative water molecule groups (H2O)n, etc.

[0042] The ionization needle head of the ionization needle device 103 is an elongated conductive metal needle, usually made of tungsten, zirconium or other materials. The ionization needle device 103 generates ionization by discharging the ionization needle head to knock out electrons from air molecules. The water mist generated by the water mist excitation device 101 can adsorb negative ions such as O2- negative molecules generated by the ionization of the ionization needle device 103, and be absorbed by the negative ion water mist generated by the water mist excitation device 101 to generate O2- negative molecule groups [O2-(H2O)n], and further make the negative ion water mist attach more negative ions to effectively increase the negative ion concentration.

[0043] As shown in Figure 2 , a control method of a water negative ion generating device 100 provided by an embodiment of the present application, the method is applied to Figure 1 the water negative ion generating device 100 as shown, and the control method comprises the following steps:

[0044] S201: Obtain a water shortage state of a water supply system 102;

[0045] S202: According to the water shortage state of the water supply system 102, issue a control instruction to control the water mist excitation device 101 and the ionization needle device 103 to run or stop running.

[0046] The above-mentioned method provided by the embodiment of the present application can control the water mist excitation device 101 and the ionization needle device 103 to run or stop running according to the water shortage state. When there is water in the water tank, the water mist excitation device 101 and the ionization needle device 103 are controlled to run at the same time. Not only the negative ion water mist generated by the water mist excitation device 101, but also the negative ion content in the negative ion water mist is increased through the ionization needle device 103. At the same time, the water mist excitation device 101 and the ionization needle device 103 are controlled to run or stop running according to the water shortage state. Compared with the prior art that cannot provide negative ions as long as there is water shortage, negative ions can be continuously generated when no water mist is generated, which to some extent alleviates the problem of sharp decrease of negative ion concentration.

[0047] Reference Figure 3As shown, the water supply system 102 of the water negative ion generating device 100 includes an upper water tank 1021 and a lower water tank 1022, the upper water tank 1021 is connected with the water mist excitation device 101 for supplying water to the water mist excitation device 101; the lower water tank 1022 is installed below the upper water tank 1021 and the water mist excitation device 101 for collecting condensed water generated in the process of generating negative ion water mist.

[0048] As shown, another control method applied to the water negative ion generating device 100 provided by the embodiment of the present application includes the following steps: Figure 4

[0049] S401: obtaining the water shortage state of the water supply system 102;

[0050] S402: judging whether the upper water tank 1021 has water;

[0051] S403: in the case of having water, controlling the water mist excitation device 101 and the ionization needle device 103 to operate;

[0052] S404: otherwise, judging whether the lower water tank 1022 has water;

[0053] S405: if the lower water tank 1022 has water, controlling the lower water tank 1022 to supply water to the upper water tank 1021;

[0054] S406: otherwise, in the case that both the upper water tank 1021 and the lower water tank 1022 are in water shortage, controlling the water mist excitation device 101 to stop operating while keeping the ionization needle device 103 to continue operating.

[0055] Continuing to refer to Figure 3 Between the upper water tank 1021 and the lower water tank 1022, a water pump 1023 is also installed, once it is detected that the upper water tank 1021 is in water shortage while the lower water tank 1022 has water, the water pump 1023 is controlled to start working to pump water from the lower water tank 1022 to the upper water tank 1021. Only when both the upper and lower water tanks are in water shortage, the water mist excitation device 101 cannot continue to generate water mist, at this time the water mist excitation device 101 is turned off while the ionization needle device 103 is kept on to generate negative ions. In this way, the problem of sharp decline of negative ion concentration caused by water shortage can be alleviated to a certain extent.

[0056] Correspondingly, water level detectors can be respectively arranged in the upper water tank 1021 and the lower water tank 1022, which are respectively installed at the bottom or the lower middle part of the upper water tank 1021 and the lower water tank 1022 to detect and help judge whether the upper water tank 1021 and the lower water tank 1022 are in water shortage.

[0057] ​It can be understood that the user's demand for negative ions is not the same, when the negative ion concentration demand is not high, the water mist excitation device 101 can continue to work, and the ionizing needle device 103 stops working. In some possible embodiments, the ionizing needle device 103 is controlled to stop running when any of the following conditions is met:

[0058] (1) The negative ion concentration in the air is higher than the preset concentration;

[0059] (2) In response to the user's setting of a low negative ion mode;

[0060] (3) The humidity in the air is higher than the preset humidity;

[0061] (4) The current time is within the preset negative ion off period.

[0062] The water negative ion generating device 100 can be provided with a negative ion concentration detection device, which can determine whether the negative ion concentration in the air has reached the preset requirement according to the detection result. Once the preset requirement is reached, the ionizing needle device 103 can be turned off.

[0063] Further, the water negative ion generating device 100 can also be provided with a mode selected by the user, and the user can decide the high negative ion mode or the low negative ion mode by himself. Once the user selects the low negative ion mode, the ionizing needle device 103 is also turned off. When the ionizing needle device 103 is turned off, the water mist excitation device 101 can also be kept running to generate negative ion water mist with a lower concentration of negative ions.

[0064] Further, in some time periods, such as at night, too many negative ions are not needed, and therefore, a negative ion off period can also be set, and during the period, the ionizing needle device 103 is automatically turned off.

[0065] In this way, the ionizing needle device 103 can be turned off when high-concentration negative ions are not needed or when the negative ion concentration has reached the demand, thereby saving electric energy and prolonging the service life of the ionizing needle device 103.

[0066] Referring back to Figure 3 In some examples, the water negative ion generating device 100 further includes a refrigeration device 104, and the water negative ion generating device further includes a fan 105 for blowing the water mist generated by the water mist excitation device 101 out of the water negative ion generating device 100. The refrigeration device 104 is installed between the fan 105 and the ionizing needle device 103 or on the inlet side of the fan 105. Referring to Figure 8As shown in FIG, the refrigeration device 104 is schematically installed between the fan 105 and the ionization needle device 103. The fan 105 can blow the water mist generated by the water mist excitation device 101 out of the water negative ion generating device 100. The refrigeration device 104 is installed between the fan 105 and the ionization needle device 103 as a water mist generating device, increasing the humidity of the air in the air duct. As a result, the water mist molecules capture the electrons released by the ionization needle device 103 to generate more water negative ions, thereby improving the working efficiency of the water negative ion generating device 100.

[0067] Furthermore, the refrigeration device 104 is a semiconductor refrigeration device. For example, it can be a semiconductor refrigeration chip. Since the semiconductor refrigeration chip is small, quiet, and has low power consumption, it does not increase the size of the water negative ion generating device 100 and can effectively improve the concentration and efficiency of negative ion generation.

[0068] It is understandable that when both the upper water tank 1021 and the lower water tank 1022 are in a water-deficient state, the water mist excitation device 101 has to stop working. At this time, when only the ionization needle device 103 is turned on, the ionization needle device 103 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 103 to react with positive ions in the environment upon entering the environment, and cannot migrate to a long distance in the environment, thereby failing to achieve the ideal purification effect on the environment and the health-promoting effect on the human body.

[0069] In the present invention, when the water mist excitation device 101 stops running, the refrigeration device 104 is turned on. In this way, when the fan 105 is working, the humidity of the air reaching the ionization needle device 103 is increased, thereby generating water mist molecules in the air. These water mist molecules migrate in the water negative ion generating device 100, 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 103 is more easily adsorbed on the already charged negative ion water mist, thereby making the negative charge concentration of the water ions adsorbed higher.

[0070] That is to say, after the water mist excitation device 101 stops running, although there is no water mist excitation device 101 to generate negative ion water mist, by turning on the refrigeration device 104 to cool and humidify the wind sent by the fan 105, 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 103 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 105.

[0071] like Figure 5 As shown, another control method provided in an embodiment of the present application, the method specifically includes the following steps:

[0072] S501: obtaining a water shortage state of the water supply system 102;

[0073] S502: determining whether the water supply system 102 is in a water shortage state; if yes, performing steps S503-S504; otherwise, performing step S505;

[0074] S503: in the case of water shortage of the water supply system 102, controlling the water mist excitation device 101 to stop running while keeping the ionization needle device 103 to continue running;

[0075] S504: controlling the refrigeration device 104 to run;

[0076] S505: controlling the water mist excitation device 101 to run, and controlling the ionization needle device 103 to run.

[0077] In the above embodiment, once the water mist excitation device 101 is stopped while the ionization needle device 103 is kept running, the number of water mist molecules is small at this time, so the refrigeration device 104 is turned on to increase the humidity of air or air in the air duct, and more water negative ions are generated.

[0078] In some examples, the air negative ion concentration can also be obtained to determine whether to automatically turn on the refrigeration device 104. Specifically, the air negative ion concentration can be obtained first, and in the case that the air negative ion concentration is lower than a preset concentration, the refrigeration device 104 is controlled to run. On the other hand, if the negative ion concentration in the air is higher than the preset concentration, it means that the negative ion concentration meets the needs of the environment and the human body. In order to meet the energy saving requirement, the refrigeration device 104 can be temporarily turned off, and only the negative ions generated by the water mist excitation device 101 or the ionization needle device 103 can be relied on. In this way, the negative ion generation efficiency and the number of negative ions can be effectively improved, and the working effect of the water negative ion generating device 100 can be improved.
