Description

Technical Field

[0001] The present invention relates to the field of air conditioning and negative ion health care technology, and more specifically to a water negative ion generating device and a control method thereof. Background Art

[0002] Negative ions can help you sleep. On the one hand, negative ions can affect the function of the central nervous system and promote the balance of serotonin in the body. Serotonin is a neurotransmitter that can regulate mood and sleep. By increasing serotonin levels, negative ions help relax 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 to make them settle, thereby purifying the air and creating a cleaner sleeping environment. This fresh air environment helps improve respiratory function, reduce snoring and other problems, and improve sleep quality. Thirdly, negative ions 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 exciting device and a charging device, wherein the negative ion water mist exciting device includes a liquid storage cavity and a negative ion water mist exciter, wherein the negative ion water mist exciter includes a mesh exciting sheet that is driven to vibrate, and generates negative ion water mist based on friction charging by vibrating and rubbing the liquid in 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 water negative ions with high concentration of negative ions. However, when the negative ion water mist exciter generates negative ion water mist, condensed water will be generated on the device, and excessive accumulation of condensed water will affect the normal operation of the machine.

[0004] The negative ion water mist exciter needs to continuously supply water through the liquid storage cavity when working normally. When there is no water in the liquid storage cavity, the water negative ion generating module will stop working, thereby stopping the generation of water negative ions. However, when people use the water negative ion machine, they often forget to add water to the liquid storage cavity.

[0005] In a typical application scenario, when using a 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 continue running at night, resulting in interruption of negative ion release, and thus unable to play its sleep-aiding effect. For those who may be overly dependent on the sleep-aiding effect of the water negative ion machine, once the machine stops working due to lack of water, users may feel uneasy or affect their sleep quality, thus developing dependence and psychological discomfort. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a water negative ion generating device and a control method thereof, which sends a control instruction according to the water shortage state of the water supply system, controls the water mist excitation device and the ionization needle device to operate when there is no water shortage, and ensures that the ionization needle device continues to operate when there is water shortage, thereby ensuring the negative ion content in the air.

[0007] On the one hand, an embodiment of the present application provides a control method for a water negative ion generating device, wherein the water negative ion generating device includes a water mist excitation device, an ionization needle device and a water supply system, wherein the water supply system includes an upper water tank, a lower water tank and a water pump, wherein the upper water tank is connected to the water mist excitation device and is used to supply water to the water mist excitation device, wherein the lower water tank is installed below the upper water tank and the water mist excitation device to collect condensed water, wherein the water pump is connected between the upper water tank and the lower water tank, wherein the water mist excitation device is used to generate negative ion water mist by rubbing water, wherein the ionization needle device is used to generate electrons to increase the concentration of negative ions, and wherein the control method includes: When there is water in the upper water tank, controlling the water mist excitation device and the ionization needle device to operate; When the upper water tank is short of water and the lower water tank has water, controlling the water pump to enable the lower water tank to supply water to the upper water tank; and When both the upper water tank and the lower water tank are short of water, the water mist excitation device is controlled to stop running, while the ionization needle device is kept running.

[0015] The beneficial effect of the present invention lies in that the operating states of the water mist excitation device and the ionization needle device are determined according to the water shortage situation of the water supply system of the water negative ion generating device, so as to ensure that even if there is a water shortage, at least the ionization needle device is in operation, and the refrigeration device can be turned on to humidify the air in the air duct to provide water mist, so that the water mist generated by the refrigeration device can also adsorb the negative ions generated by the ionization needle device and migrate to the environment.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] 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.

[0019] The structure of the water mist excitation device 101 can refer to patent documents CN116336584A, CN116207618A, CN116053936A and CN115986569A, which is preferably based on the structure of a piezoelectric ceramic plate and a vibration plate, and produces tiny droplets by exciting the vibration plate with micropores to produce high-frequency vibration, and at the same time as the tiny droplets are produced, they are rubbed with water at high frequency through the vibration plate, 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+ negative water molecule clusters [H302-(H2O)n], HO- negative water molecule clusters OH-(H2O)n, negative water molecules -(H2O)n, etc.

[0020] The ionization needle of the ionization needle device 103 is a thin and long conductive metal needle, generally made of tungsten, zirconium and other materials. The ionization needle device 103 knocks out electrons from air molecules through the discharge effect of the ionization needle, thereby generating ionization. The water mist generated by the water mist excitation device 101 can absorb negative ions such as O2-negative molecules generated by the electrons ionized by the ionization needle device 103, and is absorbed by the negative ion water mist generated by the water mist excitation device 101 to generate O2-negative molecule groups [O2-(H2O)n], thereby causing more negative ions to attach to the negative ion water mist, effectively increasing the concentration of negative ions.

[0021] like Figure 2 As shown, a control method of a water negative ion generating device 100 provided in an embodiment of the present application is applied to Figure 1 The negative water ion generating device 100 shown in the figure, the control method comprises the following steps: S201: Acquire the water shortage status of the water supply system 102; S202: issuing a control instruction according to the water shortage state of the water supply system 102 to control the water mist excitation device 101 and the ionization needle device 103 to operate or stop operating.

[0022] The above method provided in 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 is relied on, but also the negative ion content in the negative ion water mist is increased by 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 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.

[0023] refer to Figure 3 As 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 to the water mist excitation device 101 and is used to supply 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, and is used to collect condensed water generated during the negative ion water mist generation process.

[0024] like Figure 4 As shown, another control method for a water negative ion generating device 100 provided in an embodiment of the present application comprises the following steps: S401: Acquiring the water shortage status of the water supply system 102; S402: Determine whether there is water in the upper water tank 1021; S403: In the presence of water, controlling the water mist excitation device 101 and the ionization needle device 103 to operate; S404: Otherwise, determine whether there is water in the lower water tank 1022; S405: If there is water in the lower water tank 1022, control the lower water tank 1022 to supply water to the upper water tank 1021; S406: Otherwise, when both the upper water tank 1021 and the lower water tank 1022 are short of water, the water mist excitation device 101 is controlled to stop running, while the ionization needle device 103 is kept running.

[0025] Continue to refer Figure 3 A water pump 1023 is installed between the upper water tank 1021 and the lower water tank 1022. Once it is detected that the upper water tank 1021 is short of water and the lower water tank 1022 has water, the water pump 1023 is controlled to start working and pump the water in the lower water tank 1022 into the upper water tank 1021. Only when both the upper and lower water tanks are short of water, the water mist excitation device 101 cannot generate water mist when it is turned on. At this time, the water mist excitation device 101 is turned off, and the ionization needle device 103 remains turned on to generate negative ions. This can alleviate the problem of a sharp drop in negative ion concentration caused by water shortage to a certain extent.

[0026] Correspondingly, water level detectors can be respectively set in the upper water tank 1021 and the lower water tank 1022, which are respectively installed at the bottom or lower middle position of the upper water tank 1021 and the lower water tank 1022 to detect and help determine whether the upper water tank 1021 and the lower water tank 1022 are in a water shortage state.

[0027] 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 101 can be controlled to continue working, while the ionization needle device 103 can be controlled to stop working. In some possible implementations, the ionization needle device 103 is controlled to stop working when any of the following conditions is met: (1) The concentration of negative ions in the air is higher than the preset concentration; (2) Low negative ion mode in response to user settings; (3) The humidity in the air is higher than the preset humidity; (4) The current time is within the preset negative ion off time period.

[0028] A negative ion concentration detection device can be provided on the water negative ion generating device 100 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 103 can be turned off.

[0029] Furthermore, a mode for the user to select can be set on the water negative ion generating device 100, 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 ionization needle device 103 is also turned off. When the ionization 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.

[0030] Furthermore, in some time periods, such as at night, too many negative ions are not needed, so a negative ion off time period can also be set, and the ionization needle device 103 is automatically turned off during this time period.

[0031] By means of the above method, when a high concentration of negative ions is not required or the negative ion concentration has reached the required level, the ionization needle device 103 can be turned off, thereby saving electric energy and extending the service life of the ionization needle device 103 .

[0032] Continue to refer Figure 3 As shown, 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, which is used to 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 or at the inlet side of the fan 105. Figure 8 As shown in FIG. 1 , 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, and the refrigeration device 104 is arranged between the fan 105 and the ionization needle device 103 as a water mist generating device, which increases the humidity of the air in the air duct, so that 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.

[0033] 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 in size, low in noise, and low in power consumption, it will not increase the volume of the water negative ion generating device 100, and can effectively improve the concentration and efficiency of negative ion generation.

[0034] It is understandable that when both the upper water tank 1021 and the lower water tank 1022 are in a water shortage 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 will cause the negative oxygen ions generated by the ionization needle device 103 to react with positive ions in the environment when entering the environment, and cannot migrate to a longer distance in the environment, thereby failing to achieve the ideal purification effect on the environment and the health care effect on the human body.

[0035] In the present invention, when the water mist excitation device 101 stops running, the refrigeration device 104 is turned on, so that when the fan 105 is working, the humidity of the air reaching the ionization needle device 103 will increase, 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.

[0036] 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.

[0037] like Figure 5 As shown, another control method provided by an embodiment of the present application, the method specifically comprises the following steps: S501: Acquire the water shortage status of the water supply system 102; S502: Determine whether the water supply system 102 is short of water; if so, execute steps S503-S504; otherwise, execute step S505; S503: When the water supply system 102 is short of water, the water mist excitation device 101 is controlled to stop running, while the ionization needle device 103 is kept running; S504: Control the operation of the refrigeration device 104; S505: Control the water mist excitation device 101 to operate, and control the ionization needle device 103 to operate.

[0038] In the above embodiment, once the water mist excitation device 101 is stopped and the ionization needle device 103 is kept running, the number of water mist molecules is small, so the refrigeration device 104 is turned on to increase the humidity of the air or the air in the air duct to generate more water negative ions.

[0039] In some examples, it is also possible to determine whether to automatically turn on the refrigeration device 104 by obtaining the concentration of negative air ions. Specifically, the concentration of negative air ions can be first obtained, and when the concentration of negative air ions is lower than a preset concentration, the refrigeration device 104 is controlled to operate. On the other hand, if the concentration of negative ions in the air is higher than the preset concentration, it means that the concentration of negative ions meets the needs of the environment and the human body. In order to save energy, 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 efficiency and quantity of negative ion generation can be effectively improved, and the working effect of the water negative ion generating device 100 can be improved.
