The water ion generator can use the moisture in the air to form small water droplets through condensation, and apply voltage to the small water droplets to split them into water mist composed of nano-scale charged water ions. These water ions contain a large number of hydroxyl free radicals, which are a type of hydroxyl free radical that can kill microorganisms. Hydroxyl free radicals can attach to the surface of various microorganisms, extract hydrogen ions from microorganisms, combine to become water, make the microorganisms inactive, achieve the effect of sterilization, and keep the environment clean and safe.

[0003] Although hydroxyl free radicals have bactericidal ability, due to their active reaction properties, they are easily consumed by reacting with oppositely charged particles in the air, resulting in the concentration of hydroxyl free radicals being damaged, affecting the killing of microorganisms by hydroxyl free radicals, thereby affecting the bactericidal effect of the water ion generator.

[0052] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0053] For details, please refer to Figures 1 to 6 The present application provides a water ion generating device, which may include a water ion component 10; and a negative ion component 20, wherein the negative ion component 20 and the water component are arranged at intervals, and the negative ion component 20 and the water component have the same electrical properties. The water ion component 10 can generate water ions after applying a voltage, and the main sterilization factor of the water ions is negatively charged particles or hydroxyl radicals, and the ion component can generate a large number of negative ions after applying a voltage, and the negative ions are generally mainly free electrons, and the movement speed is much higher than that of other particles, so that the propagation speed of the negative ions is greater than the propagation speed of the water ions. The large number of negative ions emitted by the negative ion component 20 can react and consume with the oppositely charged particles in the air in advance, adjust the overall electrical properties of the entire aerosol environment, reduce the consumption of water ions reacting with the oppositely charged particles, and provide an environment where water ions can survive.

[0054] Alternatively, if Figure 1 , Figure 2 and Figure 3 As shown, in the first embodiment of the present application, the water ion generating device further includes a conductive fork 40, and the conductive fork 40 includes a pair of connecting parts 41 and a conducting part 42, wherein the pair of connecting parts are electrically connected to the water ion component 10 and the negative ion component 20 respectively, and the conducting part 42 is connected to the pair of connecting parts 41, so as to apply the same voltage to the water ion component 10 and the negative ion component 20 through the conducting part 42 and the connecting part 41. In other words, when the conducting part 42 is applied with voltage, the pair of connecting parts 41 are applied with voltage to the water ion component 10 and the negative ion component 20 respectively, so that the water ion component 10 and the negative ion component 20 are applied with the same voltage and generate particles with the same electrical properties.

[0055] Preferably, if Figure 3As shown, in the first embodiment of the present application, the distance D between the water ion component 10 and the negative ion component 20 satisfies the relationship: D>U; wherein D represents the value of the distance between the end axis position of the water ion component 10 and the end axis position of the negative ion component 20, in mm; U represents the value of the voltage applied to the water ion component 10 and the negative ion component 20, in KV. With such a configuration, the end of the water ion component and the end of the negative ion component 20 are the main parts for generating water ions and negative ions. A sufficient distance needs to be maintained between the water ion component 10 and the negative ion component 20 to avoid the voltage at the end of the water ion component 10 and the end of the negative ion component 20 being too high and thus breaking through the air and causing sparks. The safety performance of the water ion generating device is improved.

[0056] Alternatively, if Figure 4 , Figure 5 and Figure 6 As shown in the second embodiment of the present application, the water ion generating device further includes a pair of conductive members 50, which are electrically connected to the water ion component 10 and the negative ion component 20, respectively, so as to apply voltage to the water ion component 10 and the negative ion component 20 respectively through the conductive members 50. The water ion component 10 and the negative ion component 20 can apply the same voltage or different voltages to adjust the ratio of water ion and negative ion generation, thereby adjusting the overall electrical properties of the entire aerosol environment formed by negative ions, and improving the sterilization effect of the water ion generating device.

[0057] Preferably, in the second embodiment of the present application, the voltage applied to the water ion component 10 is greater than that of the negative ion component 20. This arrangement can increase the proportion of water ions generated by the water ion generating device and improve the sterilization effect of the water ion generating device. The voltage applied to the water ion component 10 can be implemented as a voltage such as 9KV, and the voltage applied to the negative ion component 20 can be implemented as a voltage such as 3KV or 6KV.

[0058] Preferably, if Figure 6As shown, in one embodiment, the distance D between the water ion component 10 and the negative ion component 20 satisfies the relationship: D>U1+U2; wherein D represents the value of the distance between the end axis position of the water ion component 10 and the end axis position of the ion generating head, in mm; U1 represents the value of the voltage applied to the water ion component 10, in KV; U2 represents the value of the voltage applied to the negative ion component 20, in KV. In this way, the end of the water ion component and the end of the negative ion component 20 are the main parts for generating water ions and negative ions. A sufficient distance needs to be maintained between the water ion component 10 and the negative ion component 20 to avoid the voltage at the end of the water ion component 10 and the end of the negative ion component 20 being too high and thus breaking through the air and causing sparks. The safety performance of the water ion generating device is improved.

[0059] Furthermore, if Figure 2 and Figure 5 As shown, in one embodiment, the water ion generating device includes a fixing component 30, and the water ion component 10 and the negative ion component 20 are spaced apart from each other on the fixing component 30. The water ion component 10 and the negative ion component 20 are limited by the fixing component 30 to maintain a distance to avoid the voltage at the end of the water ion component 10 and the end of the negative ion component 20 being too high to break through the air and cause ignition.

[0060] Alternatively, if Figure 2 and Figure 5 As shown, in one embodiment, the water ion component 10 includes a head fixing portion 12 fixed to the fixing component 30 and a water ion generating head 11 arranged on the head fixing portion 12, and the water ion generating head 11 has a plurality of pore structures. The pore structure can absorb and store moisture in the air, and after the water ion generating head 11 is subjected to voltage, the moisture stored in the pore structure can be decomposed into water ions. The water ion component 10 can be implemented as some rod-shaped bodies having the pore structure.

[0061] Optionally, in one embodiment, the pore structure is a capillary structure, a 3D foam structure or a combination of one or more porous structures. The water ion generating head 11 can be a plurality of capillaries, and the pore volume of the capillary is usually greater than 10% of the volume of the water ion emitting head, so as to store more water. The 3D foam structure can be some porous structures such as foam metal, foam nickel, sponge, etc. The porous structure can be a porous structure such as activated carbon.

[0062] Alternatively, if Figure 2 and Figure 5As shown, in one embodiment, the negative ion component 20 includes a brush head fixing portion 22 fixed to the fixing component 30 and a negative ion brush head 21 disposed on the brush head fixing portion 22. The negative ion brush head 21 can be composed of a conductive brush or a steel needle.

[0063] Optionally, in one embodiment, the water ion component 10 and the negative ion component 20 are made of conductive materials or non-conductive materials mixed with conductive components. The conductive material can be carbon fiber, aluminum oxide, conductive molecular sieve, conductive zeolite, activated carbon and other materials. The non-conductive material can be some polymer plastic materials such as ABS and PC. The water ion emitter can also be given conductive properties by coating or impregnating conductive materials such as conductive glue, metal powder, conductive ink, graphite, semiconductors, etc.

[0064] Furthermore, if Figure 3 and Figure 6 As shown, in one embodiment, the end of the negative ion component 20 protrudes more than the end of the water ion component 10. It can be understood that after the negative ion component 20 and the water ion component 10 are arranged, the end of the negative ion component 20 protrudes further to the outside of the water ion generating device than the end of the water ion component 10, and the end of the negative ion component 20 protrudes further to the outside than the water ion component 10, so that the negative ions generated by the negative ion component 20 can diffuse before the water ions generated by the water ion component 10.

[0065] Preferably, in one embodiment, the distance between the end of the negative ion component 20 and the fixed component 30 is greater than the distance between the end of the water ion component 10 and the fixed component 30. In other words, when the negative ion component 20 and the water ion component 10 are arranged in the fixed component, the end of the negative ion component 20 is farther from the fixed component 30 than the end of the water ion component 10. In this way, the negative ions generated by the negative ion component 20 can diffuse earlier than the water ions generated by the water ion component 10, so as to adjust the overall electrical properties of the entire aerosol environment in advance and reduce the consumption of water ions reacting with particles of opposite electrical properties.

[0066] Preferably, since the water ions and the negative ions have the same electrical properties, the water ions and the negative ions will repel each other after being emitted, resulting in a distance between them becoming increasingly greater. Figure 3 and Figure 6As shown, in one embodiment, the angle α between the water ion component 10 and the negative ion component 20 is between 0° and 10°. When the angle α between the water ion component 10 and the negative ion component 20 is greater than 10°, the water ions and the negative ions will first gather and then diffuse, which is not conducive to the propagation of the water ions and the negative ions. When the angle α between the water ion component 10 and the negative ion component 20 is less than 0°, the diffusion of the water ions and the negative ions will be aggravated. When the angle α between the water ion component 10 and the negative ion component 20 is between 0° and 10°, the water ions and the negative ions are more concentrated and can be propagated farther.

[0067] More preferably, in one embodiment, the distance between the end of the water ion component 10 and the end of the negative ion component 20 is smaller than the distance between the tail of the water ion component 10 and the tail of the negative ion component 20. In this way, the end of the water ion component 10 is closer to the end of the negative ion component 20, and the generated water ions and negative ions are more concentrated and can spread farther.

[0068] Furthermore, the present application provides an air outlet device, comprising: a fan assembly; and a water ion generator as described above, the water ion generator being connected to the air outlet duct of the fan assembly. The water ions and negative ions generated by the water ion generator can diffuse into the air outlet duct, and then the wind generated by the fan assembly is blown to the outside, so that the negative ions can neutralize the electric charge in the environment, provide an environment in which the water ions can survive, and enable the water ions to kill bacteria and microorganisms in the environment.

[0069] Preferably, in one embodiment, the water ion generator is at least partially disposed in the air outlet duct. With such an arrangement, when the fan assembly is discharging air, the air can be sent into the water ion generator, and the water ions and negative ions are directly brought from the water ion generator to the air outlet duct of the fan assembly, thereby increasing the diffusion speed of the water ions and negative ions of the water ion generator.

[0070] In particular, further, if Figure 7 As shown, the present application provides a method for controlling a water ion generating device, and the method for controlling a water ion generating device comprises the following steps:

[0071] a. After the negative ion component is started and runs for t1 time, the negative ion component is turned off;

[0072] b. Start the water ion component and after it runs for t2 time, shut down the water ion component; and

[0073] c. Repeat step a and step b until sterilization is completed.

[0074] In this way, in step a, the negative ion component continuously generates negative ions during the time t1, and a large number of negative ions react and consume with the oppositely charged particles in the air, thereby adjusting the overall electrical properties of the entire aerosol environment; in step b, the water ion component generates a large number of water ions at time t2 and diffuses to the outside to kill microorganisms and bacteria in the outside. In step c, the microorganisms and bacteria in the outside can be continuously eliminated by continuously cycling step a and step b until the sterilization is completed.

[0075] Preferably, if Figure 8 As shown, in one embodiment, the step a includes the following steps:

[0076] a1, start the negative ion component to run for t1 time; and

[0077] a2. Turn off the negative ion component and maintain time t3.

[0078] In this way, in step a1, the negative ion component generates negative ions within the time t1 to adjust the overall electrical properties of the entire aerosol environment; in step a2, turning off the negative ion component for t2 time can eliminate the static electricity accumulated on the surfaces of the inner wall of the product and the external wall caused by the continuous generation of negative ions in step a1.

[0079] Preferably, if Fig. 9 As shown, in one embodiment, the step c comprises the following steps:

[0080] c1, looping step a and step b for n times;

[0081] c2, turning off the negative ion component and the water ion component for t4 time; and

[0082] c3. Repeat step c1 and step c2 until sterilization is completed.

[0083] In this way, in step c1, the water in the water ion component is decomposed and consumed by repeatedly cycling the above steps a and b; in step c2, by closing the negative ion component and the water ion component for t4 time, the water ion component reabsorbs the water in the air to replenish the water consumed by the water ion component.

[0084] For example, in one embodiment, in step e, n=5, t4 time=t1 time. In other words, after the water ion generating device cycles through step a, step b and step c for 5 times, the water ion component and the negative ion component need to be closed for t1 time to replenish the water in the water ion component.

[0085] Optionally, in one embodiment, the ratio of the t1 time to the t2 time is between 5:3 and 7:1. When the ratio of the t1 time to the t2 time is 7:1, 6:1, 7:2 or 5:3, the water ion generating device can achieve a better sterilization effect.

[0086] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
