Description

[0002] With the research and development of water ion technology, a sterilization equipment based on water ion generator has emerged. The water ion generator can decompose the moisture in the air and generate a large number of water ions containing hydroxyl free radicals. Hydroxyl free radicals can attach to the surface of various microorganisms, extract hydrogen ions from the microorganisms, combine to become water, make the microorganisms lose their activity, achieve the effect of sterilization, and keep the environment clean and safe.

[0003] Although hydroxyl radicals can make microorganisms inactive, the bactericidal ability of hydroxyl radicals is based on the contact between hydroxyl radicals and microorganisms. Since the volume of microorganisms in the environment is small, the probability of contact with hydroxyl free radicals is low.

[0053] For details, please refer to Figures 1 to 4 The present application provides a water ion generating device, which may include: at least one water ion component 11 and a plurality of ion components 12, wherein the ion component 12 includes at least one positive ion component 121 and at least one negative ion component 122, wherein the water ion component 11 and the negative ion component 122 are negatively charged, and the positive ion component 121 is positively charged. The water ion component 11 and the ion component 12 are arranged at intervals. It can be understood that the positive ion component 121 can emit a large number of positive ions, which collide with microorganisms in the environment, so that some microorganisms in the environment carry positive electricity, and the negative ion component 122 can emit a large number of negative ions, which collide with microorganisms in the environment, so that some microorganisms in the environment carry negative electricity, and microorganisms carrying opposite charges attract each other to produce inelastic collisions, and the microorganisms after the collision neutralize each other's charges, and the microorganisms are condensed into larger microorganism particles, which is conducive to the condensation of pollutants. The contact area between the water ions generated by the water ion component 11 and the microorganism particles can be increased, and the killing rate of water ions on microorganisms can be improved.

[0054] More specifically, if Figure 1 As shown, in one embodiment, the water ion generating device comprises a plurality of water ion components 11, each of the water ion components 11 and the ion component 12 constitutes a generating unit 10, and the generating units 10 are arranged at intervals. When the ion component 12 in the generating unit 10 is a positive ion component 121, the generating unit 10 can generate water ions and positive ions; when the ion component 12 in the generating unit 10 is a negative ion component 122, the generating unit 10 can generate water ions and negative ions. The generating unit 10 can generate ions as a single component, or can be used in combination to generate ions.

[0055] Preferably, if Figure 4As shown, in one embodiment, the distance D1 between the water ion component 11 and the ion component 12 satisfies the relationship: D1>U; wherein D1 represents the value of the distance between the end axis position of the water ion component 11 and the end axis position of the ion component 12 in the generating unit 10, in mm; U represents the value of the total voltage applied to the water ion component 11 and the ion component 12, in KV. With such a configuration, the end of the water ion component and the end of the ion component 12 are the main parts for generating water ions and ions, and a sufficient distance needs to be maintained between the water ion component 11 and the negative ion component 122 to avoid the voltage at the end of the water ion component 11 and the end of the negative ion component 122 being too high and thus breaking through the air and causing ignition, thereby improving the safety performance of the water ion generating device.

[0056] Preferably, if Figure 3 As shown, in one embodiment, the distance D2 between the two generating units 10 satisfies the relationship: D2>|U1-U2|; wherein D2 represents the value of the distance between the end axis position of the water ion component 11 in one generating unit 10 and the end axis position of the water ion component 11 in another generating unit 10, in mm; U1 represents the value of the voltage applied to the water ion component 11, in KV; U2 represents the value of the voltage applied to the negative ion and positive ion components 121, in KV. With such a configuration, a sufficient distance can be maintained between the two generating units 10 to avoid the phenomenon of excessive voltage at the end of the water ion component 11 and the end of the positive ion component 121, which may break through the air and cause sparks, thereby improving the safety performance of the water ion generating device.

[0057] Furthermore, if Figure 2 As shown, in one embodiment, the water ion generating device includes a fixing component 20; the water ion component 11 and the ion component 12 are spaced apart from each other on the fixing component 20. The water ion component 11 and the ion component 12 are limited by the fixing component 20 to maintain a distance between them, so as to avoid the voltage at the end of the water ion component 11 and the end of the ion component 12 being too high and thus breaking through the air and causing ignition.

[0058] Alternatively, if Figure 2 As shown, in one embodiment, the water ion component 11 includes a head fixing portion 112 fixed to the fixing component 20 and a water ion generating head 111 disposed on the head fixing portion 112, and the water ion generating head 111 has a plurality of pore structures. The pore structure can absorb and store moisture in the air, and after the water ion generating head 111 is subjected to voltage, the moisture stored in the pore structure can be decomposed into water ions. The water ion component 11 can be implemented as some rod-shaped bodies having the pore structure.

[0059] Optionally, in one of the embodiments, 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 111 may be a plurality of capillaries aggregated, 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 may be some porous structures such as foam metal, foam nickel, sponge, etc. The porous structure may be a porous structure such as activated carbon.

[0060] Alternatively, if Figure 2 As shown, in one embodiment, the ion component 12 includes a brush head fixing portion 124 fixed to the fixing component 20 and an ion brush head 123 disposed on the brush head fixing portion 124. The ion brush head 123 can be composed of a conductive brush or a steel needle.

[0061] Optionally, in one embodiment, the water ion component 11 and the ion component 12 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 head can also be given conductive properties by coating or impregnating conductive materials such as conductive glue, metal powder, conductive ink, graphite, semiconductors, etc.

[0062] Preferably, if Figure 4 As shown, the end of the ion component 12 protrudes more than the end of the water ion component 11. It can be understood that in a generating unit 10, after the ion component 12 and the water ion component 11 are arranged, the end of the ion component 12 protrudes further to the outside of the water ion generating device than the end of the water ion component 12, and the end of the ion component 12 protrudes further to the outside than the end of the water ion component 11. This allows the positive ions or negative ions generated by the ion component 12 to diffuse earlier than the water ions generated by the water ion component 11.

[0063] Preferably, in one embodiment, the distance between the end of the ion component 12 and the fixed component 20 is greater than the distance between the end of the water ion component 11 and the fixed component 20. In other words, when the ion component 12 and the water ion component 11 are arranged in the fixed component, the end of the ion component 12 is farther from the fixed component 20 than the end of the water ion component 11. In this way, the negative ions or positive ions generated by the ion component 12 can diffuse earlier than the water ions generated by the water ion component 11, so as to condense the microorganisms in the environment into microorganism particles in advance, thereby increasing the contact probability between the water ions and the microorganisms.

[0064] Preferably, if Figure 4As shown, in one of the embodiments, in one of the generating units 10, the angle α between the water ion component 11 and the ion component 12 is between 0° and 5°. The water ions emitted by the water ion component 11 are negatively charged, the negative ions emitted by the negative ion component 122 are negatively charged, and the positive ions emitted by the positive ion component 121 are positively charged. When the angle α between the water ion component 11 and the ion component 12 is greater than 5°, the water ions and the positive ions will attract each other and approach each other. If the water ions and the positive ions react after approaching, the water ions will be consumed. When the angle α between the water ion component 11 and the ion component 12 is less than 0°, the water ions and the negative ions will repel each other and move away, which will aggravate the diffusion of water ions and negative ions. Therefore, the angle α between the water ion component 11 and the ion component 12 is controlled between 0° and 5°, which can ensure the survival of the water ions and make the water ions, the positive ions and the negative ions spread farther.

[0065] Preferably, in one embodiment, the distance between the end of the water ion component 11 and the end of the ion component 12 is smaller than the distance between the tail of the water ion component 11 and the tail of the ion component 12. In this way, the end of the water ion component 11 is closer to the end of the ion component 12, and the generated water ions and negative ions are more concentrated and can spread farther.

[0066] Furthermore, the present application provides an air outlet device, comprising: a fan assembly; and a water ion generator as described in any of the above items, the water ion generator being connected to the air outlet duct of the fan assembly. The water ions, positive 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 positive ions and negative ions can condense microorganisms into larger microbial particles, increase the contact probability between water ions and microorganisms, and enable the water ions to kill microorganisms in the environment.

[0067] 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, negative ions and positive 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, negative ions and positive ions of the water ion generator.

[0068] Furthermore, if Figure 5 As shown, the present application provides a water ion sterilization method, which includes the following steps:

[0069] a. Run the negative ion component and the positive ion component for t1 time;

[0070] b. Turn off the positive ion component and keep the negative ion component running continuously, and start the water ion component and keep the water ion component running continuously;

[0071] c. Run the water ion component for t2 time;

[0072] d. running the positive ion component for t1 time and then shutting down the positive ion component; and

[0073] e. Repeat step c and step d until sterilization is completed.

[0074] In this way, in step a, the negative ion component and the positive ion component generate a large amount of negative ions and positive ions to condense the microorganisms in the environment; in step b, after t1 time, the negative ions and positive ions condense a part of the microorganisms in the environment, at this time, the positive ion component is turned off, the negative ion component is kept running to generate negative ions, the electrical properties in the environment are adjusted, and the water ion component is started to sterilize; in step c, after t2 time, the microorganisms condensed in step a are killed, and the positive ion component is restarted to condense the microorganisms; in step d, after t1 time, the positive ion component condenses a part of the microorganisms again; in step e, after step d is completed, the current state is that the water ion component and the negative ion component are running, the positive ion component is turned off, and step c is repeated. Within t2 time, the water ions of the water ion component kill the microorganisms condensed in step d. By repeating steps c and d, a cycle is formed in which the positive ion component and the negative ion component condense the microorganisms and the water ion component kills the microorganisms until the water ion component kills the microorganisms in the environment. In the method, the microorganisms in the environment are coagulated through step a and step d, so that the contact probability between the microorganisms in the environment and the water ions is increased, thereby improving the killing rate of the water ions on the microorganisms.

[0075] Preferably, if Figure 6 As shown, in one embodiment, the step e comprises the following steps:

[0076] e1, looping step c and step d until the water ion component runs for t4 time;

[0077] e2, turning off the water ion component and the negative ion component, turning on the positive ion generator and running it for t5 time; and

[0078] e3. Turn off the positive ion component.

[0079] With such arrangement, in step e1, after the water ion component runs for t4 time, the microorganisms in the environment are completely disinfected. In step e2, the water ion component and the negative ion component stop running. The positive ion component is turned on for t1 time, and the positive ions can neutralize the negative ions in the environment during t1 time, eliminate the excess state of negative ions in the environment, eliminate the static electricity accumulation in the environment, and avoid the sparking phenomenon caused by the human body walking in the room due to the static electricity accumulation. Finally, in step e3, the positive ion component is turned off, and at this point, the positive ion component, the negative ion component and the water ion component all stop working, and the entire water ion generating device is turned off.

[0080] Optionally, in one embodiment, the time t1, the time t2 and the time t4 satisfy the relationship t4=n×(t1+t2). The water ion component can cycle the above steps c and d n times during the continuous operation of the time t4 to fully kill the microorganisms in the environment.

[0081] Exemplarily, n=5, that is, the water ion component cycles through the above steps c and d at least 5 times during the continuous operation time t4.

[0082] Furthermore, if Figure 7 As shown, in one embodiment, the step b includes the following steps:

[0083] b1, turning off the positive ion component and keeping the negative ion component running continuously; and

[0084] b2. After the negative ion component is continuously operated for t3 time, the water ion component is started and kept operating.

[0085] In this way, in step b1, the positive ion component is turned off, and the negative ion component continues to operate, continuously generating negative ions to adjust the electrical properties in the environment; in step b2, after adjustment for time t3, the negative ion component adjusts the electrical properties in the environment to a negatively charged environment that can be generated by the water ion component, and at this time the water ion component is started to generate water ions to kill the coagulated microorganisms in step a.

[0086] Preferably, in one embodiment, the t2 time is equal to the t3 time. In this way, the time for the negative ions to adjust the electrical properties in the environment is the same as the time for the water ions to kill the coagulated microorganisms in the environment, so that the negative ion component can maintain the living environment of the water ions while preventing the negative ions in the environment from being too full and affecting the coagulation effect of the positive ions.

[0087] Preferably, in one embodiment, the ratio of the t1 time to the t2 time is between 1:6 and 2:3. When the ratio of the t1 time to the t2 time is one of 1:3, 2:3, 1:4, 1:5, 1:6, 2:7, 3:7 and 3:8, the water ion generating device can obtain a better sterilization effect.

[0088] Preferably, in one embodiment, the time t5 is equal to the time t1. With this arrangement, in step e2, after the disinfection of the time t1, the excess state of negative ions in the environment can be eliminated, thereby avoiding the generation of more positive ions and causing an excess of positive ions in the environment.

[0089] 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.

[0090] 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.
