Air treatment equipment and air purification device

Technical Field

The utility model relates to the technical field of electric appliances, in particular to air treatment equipment and an air purifying device.

Background

Some existing air conditioners are provided with an air purifying device. The air cleaning device generally includes two electrodes, a high-voltage package, and a glass tube. The two electrodes are respectively arranged on the inner side and the outer side of the glass tube. The high-voltage package loads alternating voltage energy between two electrodes to realize dielectric barrier discharge. When the air purifying device performs dielectric barrier discharge, some active substances capable of sterilizing are generated. Openings are arranged at two ends of the glass tube, so that the generated active substances can be diffused outside the glass tube.

In the use process of the air purifying device, dust and moisture in the air are easy to adhere to the inner wall and the outer wall of the glass tube, so that the problem of creepage and ignition between the two electrodes is easy to occur. If only the two ends of the glass tube are plugged to avoid dust and moisture entering the glass tube, active substances generated in the glass tube cannot diffuse out of the glass tube, and the active substances cannot be utilized, so that the sterilization efficiency of the air purification device is seriously reduced.

Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

The present embodiment proposes an air treatment apparatus capable of intake air and exhaust air, which is not limited in the treatment function of air, and for example, at least one of the treatment functions of temperature adjustment, humidification, purification, circulation, and the like may be performed on air. The air treatment device includes, but is not limited to, an air conditioner, and the air treatment device may also be a purifier, a humidifier, a fan, etc., and after the specific type of the air treatment device is determined, those skilled in the art can know the configuration of the air treatment device to implement the air treatment function, which is not described herein.

The air treatment device comprises a shell, a fan and an air purifying device. The shell is provided with an air inlet, an air outlet and an air duct. Two ends of the air duct are respectively connected with the air inlet and the air outlet. The fan is arranged in the air duct. The fan can be a cross-flow fan or a centrifugal fan. After the fan is started, air in the air duct can be driven to move from the air inlet to the air outlet, so that the air inlet sucks air in the surrounding environment into the air duct, and the air flows through the air duct and is discharged from the air outlet to the surrounding environment. The air purifying device is arranged in the air inlet, the air duct or the air outlet. The air outlet may be openable and closable, for example, a damper or air deflector may be provided at the air outlet which is movable to open or close the air outlet.

As shown in fig. 1 and 2, fig. 1 and 2 show the structure of an air cleaning device 100 in the present embodiment. The air cleaning device 100 includes an insulating chamber 3, a first electrode 1, a second electrode 2, and an ac power source 4.

The insulating chamber 3 is constructed as a closed chamber, in which a closed inner chamber 30 is arranged. The first electrode 1 is arranged outside the insulating cavity 3, and the second electrode 2 is arranged in the inner cavity 30 of the insulating cavity 3. The insulating cavity 3 is made of insulating material and has high resistivity. The insulating cavity 3 can be made of high polymer insulating materials such as vinyl chloride, polyethylene, silica gel, rubber and the like, or inorganic nonmetallic materials such as quartz glass, ceramics, apatite, mica and the like.

The first electrode 1 is a conductor, and the first electrode 1 may be made of metal or carbon fiber, such as copper, aluminum, iron, and alloys thereof. The first electrode 1 is configured as a solenoid. The pitch is the same throughout the first electrode 1. The first electrode 1 is sleeved outside the insulating cavity 3.

The second electrode 2 is a conductor, and the second electrode 2 may be made of metal or carbon fiber, such as copper, aluminum, iron, and alloys thereof. The second electrode 2 is configured as a solenoid, the pitch of the thread being the same throughout the second electrode 2. The second electrode 2 is arranged in an insulating cavity 3, and a wall surface of the insulating cavity 3 separates the first electrode 1 from the second electrode 2. The axial direction of the first electrode 1 and the axial direction of the second electrode 2 are parallel to each other. The pitch of the first electrode 1 is smaller than the pitch of the second electrode 2.

The ac power source 4 includes a first output port 41 and a second output port 42. The first output port 41 is electrically connected to the first electrode 1, and the second output port 42 is electrically connected to the second electrode 2. The ac power source 4 may apply an ac voltage between the first electrode 1 and the second electrode 2 through the first output port 41 and the second output port 42, which is smaller than a breakdown voltage of the wall surface of the insulating cavity 3, so as to avoid the wall surface of the insulating cavity 3 from being broken down. The ac voltage may be 2000 to 8000V.

In this embodiment, the insulating cavity 3 is a closed cavity, air outside the insulating cavity 3 cannot enter the insulating cavity 3, moisture and dust in the air cannot adhere to the inner surface of the insulating cavity 3, meanwhile, the inner surface and the outer surface of the insulating cavity 3 are completely isolated, and an electric spark cannot reach the outer surface of the insulating cavity 3 along the inner surface of the insulating cavity 3 or reach the inner surface of the insulating cavity 3 along the outer surface of the insulating cavity 3, so that creepage and ignition between the first electrode 1 and the second electrode 2 can be completely avoided.

Because the first electrode 1 and the second electrode 2 are solenoid electrodes, compared with the scheme that the wire electrode or the columnar electrode is used as the solenoid inner electrode in the related art, the distance between the first electrode 1 and the second electrode 2 in the embodiment is relatively short, the first electrode 1 is distributed uniformly in the inner circumference of the insulating cavity 3, and the first electrode 1 can better promote the discharge of the second electrode 2.

Since the insulating chamber 3 separates the first electrode 1 from the second electrode 2, the air cleaning device 100 can perform dielectric barrier discharge after the alternating voltage is applied to the first electrode 1 and the second electrode 2, and since the pitch of the first electrode 1 is smaller than that of the second electrode 2, the first electrode 1 is more densely distributed in space, the second electrode 2 is more sparsely distributed in space, and sterilization active materials including ozone, -OH, free electrons, oxygen radicals, and the like are mainly generated by discharging air at the first electrode 1. Thus, most of the active substances are generated outside the insulating cavity 3, and can be freely diffused into the environment outside the insulating cavity 3 along with air to sterilize, so that the air purifying device has high sterilization efficiency and odor removal efficiency.

In an exemplary embodiment, the ratio of the pitch of the second electrode 2 to the pitch of the first electrode 1 is greater than 2.

The pitch of the second electrode 2 is more than twice that of the first electrode 1, so that dielectric barrier discharge of the air purifying device 100 can be concentrated on the first electrode 1, and thus, sterilization active substances generated by the air purifying device 100 are concentrated outside the insulating cavity 3, and can be diffused into the surrounding environment to sterilize and remove odor, and the sterilization efficiency and the odor removal efficiency of the air purifying device can be further improved.

In an exemplary embodiment, the pitch of the first electrode 1 is in the range of 0.1 to 50mm and the pitch of the second electrode 2 is in the range of 0.1 to 50mm.

The range of the pitch of the first electrode 1 and the pitch of the second electrode 2 is set to be 0.1-50 mm, the generation rate of active substances such as ozone, -OH, free electrons, oxygen free radicals and the like is higher, the sterilization efficiency and the deodorizing efficiency of the air purifying device are correspondingly higher, and meanwhile, the problem of oversized first electrode 1 and second electrode 2 caused by oversized pitch can be avoided.

In an exemplary embodiment, the insulating cavity 3 includes an insulating cylinder 31. The insulating cylinder 31 is made of insulating material and has high insulating performance. Both ends of the insulating cylinder 31 are closed. The insulating cylinder 31 may be configured as a cylinder. The thickness of the insulating cylinder 31 is uniform.

The first electrode 1 is sleeved outside the insulating cylinder 31, and the first electrode 1 is coaxially arranged with the insulating cylinder 31. The insulating cylinder 31 is sleeved outside the second electrode 2, the second electrode 2 is positioned in the insulating cylinder 31, and the insulating cylinder 31 and the second electrode 2 are coaxially arranged.

Thus, since the insulating cylinder 31, the first electrode 1 and the second electrode 2 are coaxially arranged, the electric field energy distribution between the first electrode 1 and the second electrode 2 is more uniform, and dielectric barrier discharge can be more uniformly performed throughout the first electrode 1.

In an exemplary embodiment, the outer circumferential surface of the insulating cylinder 31 abuts against the inner side of the first electrode 1, and the inner circumferential surface of the insulating cylinder 31 abuts against the outer side of the second electrode 2.

Since the first electrode 1 and the second electrode 2 are respectively abutted against the outer circumferential surface and the inner circumferential surface of the insulating cylinder 31, the thickness of the side wall of the insulating cylinder 31 is the discharge gap between the first electrode 1 and the second electrode 2, and the discharge gap between the first electrode 1 and the second electrode 2 can be as small as possible under the condition that the thickness of the side wall of the insulating cylinder 31 is fixed, so that the discharge intensity of the first electrode 1 can be larger, the generation rate of active substances is higher, and the sterilization efficiency and the deodorization efficiency of the air purification apparatus 100 can be further improved.

In one exemplary embodiment, the sidewall thickness of the insulating cylinder 31 is set to be less than 1mm.

Because the thickness of the side wall of the insulating cylinder 31 is the discharge gap between the first electrode 1 and the second electrode 2, the discharge gap between the first electrode 1 and the second electrode 2 is smaller than 1mm, so that the discharge intensity of the first electrode 1 can be effectively enhanced, and the sterilization efficiency and the deodorizing efficiency of the air purifying device 100 can be further improved.

In an exemplary embodiment, the insulating cavity 3 further comprises two insulating members 32. The insulating member 32 is made of an insulating material and has good insulating properties. Two insulators 32 are provided at opposite ends of the insulating cylinder 31, respectively. One insulator 32 blocks the opening of one end of the insulating cylinder 31, and the other insulator 32 blocks the opening of the other end of the insulating cylinder 31.

The two insulators 32 can seal the two openings of the insulating cylinder 31, so that air inside and outside the insulating cylinder 31 cannot be exchanged, and dust and moisture are prevented from being brought into the insulating cylinder 31 by outside air.

In one illustrative embodiment, a glue-in-place process is used to inject a liquid glue into the end of the insulating cylinder 31, and after the liquid glue has cured, an insulator 32 is formed within the end of the insulating cylinder 31. The liquid glue may be an epoxy glue or a silicone glue.

The insulating cylinder 31 is sealed by adopting a glue filling sealing process, the process is simple and easy to process, and the formed insulating piece 32 has good air tightness.

In another exemplary embodiment, the insulating cylinder 31 is a glass tube. Opposite ends of the insulating cylinder 31 are sinter-sealed.

After the second electrode 2 is placed in the glass tube, the end of the glass tube is sintered to soften the end of the glass tube, the edges of the softened end are kneaded together to seal the end of the glass tube, and after the end of the glass tube is cooled, the end of the glass tube is solidified to maintain a sealed state. The glass tube has good insulating property, low cost, simple sintering and sealing process for the end part of the glass tube and high yield.
