[0002] In modern society, air quality has become a growing concern for people. There are various harmful substances in the air, such as bacteria, viruses, odors, etc. These harmful substances have a great impact on physical and mental health.
[0003] The vehicle-mounted disinfection and deodorization system on the market widely uses a certain amount of ozone to disinfect. This method uses the strong oxidizing property of ozone to effectively destroy the cell structure of microorganisms such as bacteria and viruses, thereby achieving high-efficiency sterilization. Ozone disinfection has certain advantages, but also has certain potential risks, so the state and various agencies have different standards for ozone control.
[0004] Therefore, in a quantitative ozone environment, the sterilization process is relatively slow, which may result in ineffective and timely inhibition and disinfection. Secondly, during the process of ozone inhibition and sterilization, it may cause damage to the interior materials of the vehicle, especially to rubber, plastic and fabric materials, which may cause their aging to accelerate.

[0028] In order to more fully understand the technical content of the present application, the present application will be further introduced and explained in combination with the drawings and specific embodiments; it should be noted that if there are "first", "second" and the like in the text, they are used to distinguish different components, etc., and do not represent the order, nor limit "first" and "second" to be different types.
[0029] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments; based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
[0030] EMBODIMENT
[0031] As Figures 1 to 4As shown, the vehicle-mounted water ion sterilization and odor removal non-consumable purification device shown in the embodiment directly installs on the air conditioning ventilation pipe of the vehicle during use, and specifically comprises a shell 1 and a circuit board 2 arranged in the shell 1. The circuit board 2 is provided with at least one ionization needle for generating water ions and at least one negative ion discharge needle for negative ions. The circuit board 2 is also provided with an electric field guide ring 23 located in front of the ionization needle. At least one Peltier element 20 abutting the ionization needle is arranged at the connection position of each ionization needle on the circuit board 2 for directly cooling the ionization needle. One surface of the shell 1 is provided with an emission port at a position corresponding to each ionization needle and negative ion discharge needle. Thus, the water ions and negative ions generated by ionization are emitted into the air conditioning ventilation pipe through the emission port and blown into the vehicle cabin through the air conditioning outlet with the air conditioning air. The hydroxyl radical of the water ion can more quickly destroy the cell wall and cell membrane of microorganisms, thereby more efficiently killing bacteria and viruses. The negative ions combine with positive ions in the air in the vehicle to form larger ion clusters and settle to the ground, thereby reducing the concentration of suspended particulate matter, dust, pollen and other pollutants in the air to achieve the purpose of purifying the air in the vehicle. Secondly, the reaction speed of the hydroxyl radical is faster, and the disinfection process can be completed in a shorter time, so the influence of the hydroxyl radical on the human body is relatively small at a low concentration. Thirdly, the hydroxyl radical does not produce harmful by-products during the disinfection process like ozone, so it does not cause secondary pollution to the vehicle environment. In addition, the decomposition product of the hydroxyl radical is only water without any residue, which is more environmentally friendly. Finally, the disinfection process of the hydroxyl radical has less potential damage to sensitive equipment because it does not corrode certain materials like ozone. Therefore, using the hydroxyl radical for vehicle disinfection not only effectively improves the air quality in the vehicle and protects the health of the passengers, but also better protects the internal facilities of the vehicle.
[0032] In the above, by integrating water ion and negative ion functions on the same circuit board, integrated application and improved purification capacity are achieved, and the purification device is conveniently installed on the ventilation duct for use. In order to solve the problem of excessive heat generated by the circuit board due to the integration of water ion and negative ion functions, Peltier elements abutting the ionization needles are directly arranged on the circuit board to effectively dissipate heat on the circuit board, and the heat dissipation effect is good, thereby improving the service life of the circuit board and avoiding damage to the circuit board due to excessive heat
[0033] Specifically, as Figures 1 to 4As shown, the circuit board 2 is provided with two first ionization needles 21 and second ionization needles 22 arranged adjacent to and parallel to each other, and the electric field guide ring 23 is provided with two adjacent guide holes 24, and the release ends (i.e. the free ends) of the first ionization needles 21 and the second ionization needles 22 are respectively and correspondingly directed to the center positions of the two guide holes 24; the shell 1 is provided with a first emission port 11 and a second emission port 12 at positions corresponding to the two guide holes 24, and the double ionization needle arrangement makes the sterilization and odor removal capacity stronger; during operation, the Peltier element 20 cools the two ionization needles, so that the water molecules in the air are condensed into liquid water (i.e. water droplets) on the two ionization needles after contacting the two ionization needles, thereby providing the water source required for generating negative ions, and a high-voltage pulse area is formed between the first ionization needles 21 and the second ionization needles 22 and the electric field guide ring 23, and the water droplets on the first ionization needles 21 and the second ionization needles 22 are ionized and decomposed under the action of the high-voltage pulse, thereby generating negative ions (i.e. hydroxyl ions), and the negative ions form an ion flow flowing to the direction of the guide holes 24 under the action of the positively charged electric field guide ring 23, and the ion flow is finally collected in the guide holes 24 and then blown out through the first emission port 11 and the second emission port 12, and a negative pressure is formed between the first ionization needles 21 and the second ionization needles 22 and the electric field guide ring 23, and the external air flows into the space between the first ionization needles 21 and the second ionization needles 22 and the electric field guide ring 23 to continue electrolysis under the action of the negative pressure, thereby generating a continuous water ion flow.
[0034] It can be understood that the first ionization needles 21 and the second ionization needles 22 are electrically connected to the negative output end on the circuit board, and the electric field guide ring 23 is electrically connected to the positive output end on the circuit board.
[0035] As preferred, as shown in the drawings, Figures 3 to 4 one end of each of the first ionization needles 21 and the second ionization needles 22 is provided in and electrically connected to the circuit board 2, i.e. one end of each of the first ionization needles 21 and the second ionization needles 22 penetrates through the circuit board 2; the circuit board 1 is provided with two Peltier elements 20 abutting against the ionization needles at the positions where the first ionization needles 21 and the second ionization needles 22 are connected, and the two Peltier elements 20 are arranged on the two surfaces of the circuit board 2 and located on the two sides of the ionization needles, i.e. each of the first ionization needles 21 and the second ionization needles 22 is cooled by two Peltier elements 20, and the ionization needles are cooled by the two surfaces of the circuit board 2 at the same time, thereby improving the heat dissipation efficiency and reducing the heat conducted to the circuit board from the two ends of the ionization needles.
[0036] As preferred, as shown in the drawings, Figures 1 to 2 the first emission port 11 and the second emission port 12 are both circular holes with a hole diameter larger than that of the guide holes 24, so as to facilitate the ion flow to be emitted outward.
[0037] As preferred, as shown in the drawings, Figure 3As shown, both sides of the electric field guiding ring 23 are electrically connected to the circuit board 2 through right-angled support feet 25, so that the electric field guiding ring 23 is suspended in front of the ends of the two ionization needles.
[0038] In one embodiment, such as Figures 1 to 4 As shown, the circuit board 2 is provided with two adjacent and parallel first negative ion discharge needles 26 and second negative ion discharge needles 27. By setting up double negative ion discharge needles, its purification ability is enhanced. The outer shell 1 is provided with a third emission port 13 and a fourth emission port 14 at the positions corresponding to the first negative ion discharge needles 26 and second negative ion discharge needles 27, respectively. The release ends of the first negative ion discharge needles 26 and second negative ion discharge needles 27 protrude from the third emission port 13 and the fourth emission port 14, respectively, so that the negative ions generated by the ionization of the first negative ion discharge needles 26 and second negative ion discharge needles 27 are directly placed outside the outer shell 1. The negative ions generated do not need to be emitted outward through the action of the electric field guiding ring. In conjunction with the air conditioning ventilation pipe, the air conditioning air transported in the air conditioning ventilation pipe carries the negative ions generated by the ionization of the first negative ion discharge needles 26 and second negative ion discharge needles 27 outward.
[0039] In another embodiment, such as Figures 1 to 2 As shown, the third emission port 13 is a round hole, and the fourth emission port 14 is a square hole. The length and width of the square hole are at least three times the outer diameter of the second negative ion discharge needle 27. By using the designed large-sized square hole, the position of the second negative ion discharge needle 27 in the square hole can be finely adjusted to adapt to the production and installation tolerances between the shell and the circuit board, so as to avoid the inability to install or the excessive installation misalignment caused by the tolerances during the production and / or assembly of the two, which would affect the use.
[0040] In one embodiment, such as Figures 3 to 4 As shown, one end of the circuit board 2 is also provided with a connection terminal 28 for connecting to the vehicle power supply, and one side of the housing 1 has an opening 10 at the position corresponding to the connection terminal 28.
[0041] In one embodiment, such as Figures 1 to 2 As shown, a raised boss 15 is provided on one surface of the outer shell 1. The first emission port 11 and the second emission port 12 are opened at one end of the boss 15, and the third emission port 13 and the fourth emission port 14 are opened at the other end of the boss 15, so that the two ionization needles and the two negative ion discharge needles are located at two ends, avoiding mutual interference and affecting the ionization of the air. A positioning part 151 is provided with a protrusion in the middle of one end of the boss 15. When the vehicle-mounted water ion sterilization and deodorization consumable-free purification device is installed on the outside of the air conditioning ventilation pipe of the vehicle, a window matching the shape of the boss is opened on the air conditioning ventilation pipe, so that the boss is inserted into the window, and then the ion emission generated by the two ionization needles and the two negative ion discharge needles enters the air conditioning ventilation pipe. The presence of the positioning part 151 can prevent the purification device from being installed backwards, and plays a role in preventing mistakes and positioning.
[0042] In another embodiment, as shown in Figure 4 The circuit board 2 is provided with a high-voltage generating module 29 (i.e. high-voltage module) for providing DC negative high voltage for the two positive ion discharge needles and the two negative ion discharge needles.
[0043] In another embodiment, the shell is composed of an upper shell and a lower shell which are buckled to each other, and adopts a detachable structure to facilitate the installation of the internal circuit board.
[0044] The above describes the technical solutions provided by the embodiments of the present application in detail, and the principles and implementation manners of the embodiments of the present application are described by applying specific examples; the above description of the embodiments is only applicable to helping understand the principles of the embodiments of the present application; meanwhile, for those skilled in the art, the embodiments of the present application will have changes in specific implementation manners and application ranges, and the above description of the present application should not be understood as limiting the present application.
