Description

Technical Field

[0001] This utility model relates to the field of hand dryers, specifically an air filtration structure for a plasma hand dryer. Background Technology

[0002] Currently, hand dryers generate a lot of heat during operation, which may cause damage with prolonged use. Utility Model Content

[0003] The purpose of this invention is to provide an air filtration structure for a plasma hand dryer to solve the problems mentioned in the background art, which has the advantage of reducing the heat of the hand dryer.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an air filtration structure for a plasma hand dryer, comprising a housing, an air inlet on the lower side of the housing, a plasma chamber and an air inlet chamber communicating with the air inlet, a first positioning plate and a second positioning plate that are interlocked at one end of the air inlet chamber, a first sealing plate and a second sealing plate that are jointly provided at one end of the first positioning plate and the second positioning plate, an air outlet at one end of the first sealing plate and the second sealing plate, a plasma generator installed inside the plasma chamber, one side of the plasma chamber communicating with the outside, a circuit board installed inside the air inlet chamber, and an aluminum radiator installed on the circuit board.

[0005] By adopting the above technical solution, the main working principle of the plasma generator is as follows: A low voltage is boosted to high and negative high voltages through a boost circuit. These high and negative high voltages ionize the air (mainly oxygen), generating a large number of positive and negative ions. The number of negative ions is approximately 1.5 times that of positive ions. The positive and negative ions generated simultaneously by the plasma generator release a huge amount of energy during the instantaneous neutralization process in the air, leading to the death of bacteria and achieving a sterilization effect. Because the number of negative ions is greater than the number of positive ions, the excess negative ions remain suspended in the air, thus achieving the effects of eliminating smoke, removing dust, eliminating odors, improving air quality, and promoting human health.

[0006] It is worth noting that in the independent air intake structure system, when the plasma-purified air passes through the air intake channel, the heat is carried away by the aluminum heat sink on the circuit board, which reduces the power consumption of the heater and thus saves electricity.

[0007] As a further embodiment of this utility model: the housing includes an upper housing and a lower housing. The lower housing is integrally connected to a first positioning plate. The first positioning plate has an inwardly recessed first slot in its circumferential direction. The first positioning plate is connected to a second positioning plate through the first slot. The second positioning plate has a matching first protrusion integrally connected to the side facing the first slot. The first positioning plate has a locking block integrally connected to the side facing the second positioning plate. The second positioning plate has a second slot that cooperates with the locking block. A hair dryer is installed inside the upper housing. The upper housing is integrally connected to first placement plates at both ends of the hair dryer. The second positioning plate is integrally connected to a second placement plate that cooperates with the first placement plate.

[0008] By adopting the above technical solution, the second positioning plate is moved toward the first positioning plate until the two are engaged. The engagement process is that the first protrusion on the second positioning plate is engaged into the first slot, and at the same time the locking block will be engaged into the second slot, thus achieving engagement. The blower blows towards the air outlet, and a negative pressure is formed at the back of the blower to form a circulation. The first placement plate and the second placement plate work together to increase the stability of the blower when it is between the first positioning plate and the second positioning plate.

[0009] Preferably, the lower housing is integrally connected to an air inlet chamber on one side of the first sealing plate, and a first air inlet hole is provided on one side of the air inlet chamber. A second air inlet hole is also provided on the side of the first positioning plate.

[0010] Preferably, an air inlet and an air outlet are provided at the bottom of the housing, and multiple air outlets are provided.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The main working principle of a plasma generator is as follows: A low voltage is boosted to high and negative high voltages via a step-up circuit. These high and negative voltages ionize the air (mainly oxygen), generating a large number of positive and negative ions. The number of negative ions is approximately 1.5 times that of positive ions. The simultaneous generation of positive and negative ions by the plasma generator releases a tremendous amount of energy during the neutralization process in the air, leading to the death of bacteria and achieving a sterilization effect. Because the number of negative ions is greater than that of positive ions, the excess negative ions remain suspended in the air, thus eliminating smoke, dust, and odors, improving air quality, and promoting human health.

[0013] It is worth noting that in the independent air intake structure system, when the plasma-purified air passes through the air intake channel, the heat is carried away by the aluminum heat sink on the circuit board, which reduces the power consumption of the heater and thus saves electricity.

[0029] Working principle:
