DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0027] like Figure 1-6 A negative ion generator is shown, comprising a host 10 and a high-voltage generating assembly and a control circuit board 20 arranged in the host 10, wherein the high-voltage generating assembly comprises a first high-voltage generator 21, a first voltage converter 23 electrically connected to the first high-voltage generator 21, a second high-voltage generator 22 and a second voltage converter 24 electrically connected to the second high-voltage generator 22, the input end of the first high-voltage generator 21 and the input end of the second high-voltage generator 22 are electrically connected to the control circuit board 20, and further comprises a first negative ion releasing electrode box 30, a second negative ion releasing electrode box, a first high-voltage electrode plate 40, and a second high-voltage electrode plate, the first voltage converter 23 is electrically connected to the first negative ion releasing electrode box 30 or the first high-voltage electrode plate 40 through a connector, the second voltage converter 24 is electrically connected to the second negative ion releasing electrode box or the second high-voltage electrode plate through a connector, a first grounding terminal electrically connected to the first high-voltage generator 21 and a second grounding terminal electrically connected to the second high-voltage generator 22 are arranged at the front end of the host 10, and further comprises a first grounding electrode plate 50 electrically connected to the first grounding terminal and a second grounding electrode 312 plate electrically connected to the second grounding terminal.

[0028] Specifically, when using the product of the present application, such as when using it in a car, first electrically connect the first negative ion releasing electrode box 30 and the second negative ion releasing electrode box to the first voltage converter 23 and the second voltage converter 24 respectively, and then install the first negative ion releasing electrode box 30 at the air-conditioning outlet position located at the front seat of the car, and install the second negative ion releasing electrode box at the air-conditioning outlet position located at the rear seat of the car, so that the negative ions generated by the first negative ion releasing electrode box 30 and the second negative ion releasing electrode box can be evenly distributed in the car body. When used in a relatively small space, the first high-voltage electrode plate 40 and the second high-voltage electrode plate need to be placed at the position where negative ions need to be introduced, and the first grounding electrode plate 50 and the second grounding electrode 312 plate need to be placed on the other side of the position where negative ions need to be introduced, so that the position where negative ions need to be introduced is located between the first high-voltage electrode plate 40 and the first grounding electrode plate 50 or between the second high-voltage electrode plate and the second grounding electrode 312 plate, and start the present application. Please use the product so that the first high-voltage electrode plate 40 and the second high-voltage electrode plate generate negative ions, and the negative ions will move toward the first grounding electrode plate 50 or the second grounding electrode 312 plate, that is, move toward the part where negative ions need to be introduced, and thus enter the human body through the skin. Of course, the first negative ion releasing electrode box 30 can also be electrically connected to the first voltage converter 23, and the first negative ion releasing electrode box 30 can be installed at the air outlet of the air conditioner so that the negative ions generated by the first negative ion releasing electrode box 30 can be evenly distributed in the air. At the same time, the first high-voltage electrode plate 40 or the second high-voltage electrode plate is electrically connected to the second voltage converter 24, and then the first high-voltage electrode plate 40 or the second high-voltage electrode plate electrically connected to the second voltage converter 24 is fitted to the human skin, so that the negative ions generated by the first high-voltage electrode plate 40 or the second high-voltage electrode plate can enter the human body through the skin. The two methods are carried out simultaneously in the narrow space inside the car to efficiently obtain negative ions, purify the air, and promote health.

[0029] More specifically, by configuring a voltage converter between the high voltage generator and the high voltage electrode plate or the negative ion releasing electrode box, the DC high voltage output by the high voltage generator is converted into a DC source voltage containing a specific pulsating component through the voltage converter. Since the voltage converter changes the waveform of the voltage, it can provide a stable voltage to the high voltage electrode plate or the negative ion releasing electrode box, thereby improving the corona discharge efficiency between the negative ion releasing electrode box or the high voltage electrode plate and the grounding electrode plate, so that the device can continuously and stably generate small-particle negative ions, that is, the generation efficiency of small-particle negative ions is improved.

[0030] Specifically, the first negative ion releasing electrode box 30 has the same structure as the second negative ion releasing electrode box. The first negative ion releasing electrode box 30 includes a shell 31, on which an air duct 311 is opened. A grounding electrode 312 is arranged at the upper end of the air duct 311, and a discharge electrode 313 corresponding to the grounding electrode 312 is arranged at the lower end of the air duct 311. The discharge electrode 313 is electrically connected to the first voltage converter 23, and the grounding electrode 312 is electrically connected to the first grounding end.

[0031] During operation, a +DC12V voltage is input into the first high-voltage generator 21 from an external power source such as a car, and the voltage is boosted by the first high-voltage generator 21, so that the output end of the first high-voltage generator 21 generates a negative DC high voltage of about -6KV. The input end of the first voltage converter 23 is electrically connected to the output end of the first high-voltage generator 21 through a wire, and the input negative DC high voltage is converted into a pulsating negative DC high voltage and transmitted to the discharge electrode 313. The discharge electrode 313 cooperates with the grounding electrode 312 to discharge so as to ionize the air passing through the air duct 311.

[0032] The negative ions generated by the discharge electrode in this application are small-particle negative ions that can enter the organism (in this embodiment, the organism is the human body). It is understandable that the following definition is given in the book "Environmental Health and Negative Oxygen Ions" written by Professor Lin Jinming, a doctoral supervisor at Tsinghua University and an expert at the Chinese Academy of Sciences: air negative ions vary in size and can be divided into three categories according to the size of the particle diameter: small ions (0.001-0.003μm), medium ions (0.003-0.03μm), and large ions (0.03-0.1μm); among them, small-particle negative ions are also called small ions or light ions. Therefore, the particle diameter of the small-particle negative ions referred to in this embodiment is 0.001-0.003μm, which has good biological activity and the characteristics of long transmission distance, and can easily penetrate the human blood-brain barrier to act on the human body.

[0033] Specifically, an anti-electricity grid 32 is provided at the air inlet and the air outlet of the air duct 311 to prevent the user's fingers from accidentally touching the discharge electrode 313 and causing electric shock.

[0034] Clips are provided on both sides of the housing 31 to facilitate the user to install the first negative ion releasing electrode box 30 or the second negative ion releasing electrode box at the air outlet of the air conditioner.

[0035] More specifically, the first high-voltage electrode plate 40 has the same structure as the second high-voltage electrode plate. The first high-voltage electrode plate 40 includes a copper sheet 41 electrically connected to the first voltage converter 23 . A rubber layer 42 is provided on the outer surface of the copper sheet 41 . A plurality of through holes are formed on the rubber layer 42 .

[0036] During operation, the copper sheet 41 contacts the air through the through holes to ionize the air to generate negative ions. The generated negative ions will move toward the first grounding electrode plate 50 that matches it. The palm or other part of the human body is placed between the first high-voltage electrode plate 40 and the first grounding electrode plate 50 so that the generated negative ions can be absorbed by the human body through the skin.

[0037] More specifically, the rubber layer 42 is wrapped with flannel 43 to prevent the user's skin from contacting the copper sheet 41 in the through hole and causing electric shock.

[0038] More specifically, the first grounding electrode plate 50 and the second grounding electrode plate 312 are composed of metal electrodes and conductive fibers. The metal electrodes are wrapped in the conductive fibers, and the metal electrodes are electrically connected to the first grounding terminal or the second grounding terminal.

[0039] In addition, to facilitate the user to fit the first grounding electrode plate 50, the first high-voltage electrode plate 40, the second high-voltage electrode plate and the second grounding electrode 312 plate to human skin, the present application also includes a first fixing clamp 60 and a second fixing clamp. The first fixing clamp 60 and the second fixing clamp are made of insulating material. The first grounding electrode plate 50 and the first high-voltage electrode plate 40 are installed at the clamping end of the first fixing clamp 60 and are arranged opposite to each other. The second grounding electrode 312 plate and the second high-voltage electrode plate are installed at the clamping end of the second fixing clamp and are arranged opposite to each other.

[0040] When in use, it is only necessary to clamp the first fixing clip 60 and the second fixing clip at the part where negative ions need to be introduced.

[0041] Specifically, sponges are provided on the surfaces of the first fixing clip 60 and the second fixing clip to improve the comfort of the first fixing clip 60 and the second fixing clip when they are in contact with the human body.

[0042] More specifically, in order to verify whether the combination of the first high-voltage electrode plate and the first grounding electrode plate 50 has the effect of skin introduction, we conducted a simulation test with artificial skin. The structure of artificial skin is very similar to that of human skin, such as Figure 7 As shown, the negative ion releasing electrode plate and the grounding electrode plate are kept at a certain distance, and the device body with artificial skin is placed between the two. The main body of the artificial skin device body is a cylindrical container, both sides of which are covered with artificial skin as walls, and the top is opened and provided with an injection port. Physiological saline can be injected into the container chamber through the injection port. The volume is 2cc, and the two sides of the cylindrical container are fixed by two acrylic plates so that the cylindrical container can remain upright.

[0043] The experiment was carried out for 30 minutes, and the pH value and redox potential of the saline were tested. Since negative ions are negatively charged particles with a certain reducing or alkaline effect, as long as the pH value of the saline is tested to see whether it rises and the oxidation potential decreases, it proves that the negative ions released by the negative ion release electrode plate are absorbed by the artificial skin and cause the pH value and redox potential of the saline to change. The test results are as follows: Figure 8 and Fig. 9 shown.

[0044] Specifically, the surface of the host 10 is coated with an antistatic coating. Since there are high-voltage generating components inside the host 10, static dust is easily generated. Over time, the outer shell of the host 10 will turn black and discolored. Therefore, an antistatic coating is applied to the surface of the host 10 to avoid static electricity on the surface of the host 10.

[0045] In addition, the host 10 of the present application has a timing function module, uses a LCD screen to display the time, and is provided with plus and minus buttons to set the required usage time. After setting the usage time, press the "START" button to start working, and the host 10 starts countdown. Press the "START" button again to pause the countdown, and stop running after the countdown ends. The operation is simple.

[0046] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
