Description

TECHNICAL FIELD

[0001] The present application relates to the field of air purification, in particular to a secondary pollution-free air purifier assembly. BACKGROUND

[0002] The existing air purifiers are basically divided into two categories. One is passive air purifier. This type of air purifier filters and intercepts the suspended particles in the air through a filter device, thereby achieving the effect of air purification. However, this type of air purifier has consumables without exception. According to different use environments, the consumables need to be replaced in 3 months or 1 year, which is not only troublesome, but also expensive for many consumables, increasing the user's maintenance cost. In addition, when using this type of air purifier, the pollutants in the air accumulate on the filter consumables, and with the passage of time, the filter consumables are blocked, causing the filter efficiency to decrease. The pollutants remaining on the filter consumables also cause secondary pollution to the environment. The other is active air purifier. This type of air purifier mainly relies on static electricity and plasma to adsorb pollutants in the air, thereby achieving the purpose of purifying air. Although the active air purifier does not have the disadvantage of replacing consumables, the adsorbed pollutants still need to be cleaned and maintained regularly, and with the passage of time, the pollutants adsorbed in the air purifier will still cause secondary pollution to the environment. In addition, hospitals, shopping malls, cinemas and other large indoor spaces use either of the above air purification devices, and due to their large size, cleaning and maintenance work is also more laborious. The electrode structure is complex and the cost is relatively high, and it is not convenient to maintain and repair when a fault occurs. SUMMARY

[0003] In view of the above, in order to overcome the shortcomings of the prior art, the technical problem to be solved by the present application is to provide a secondary pollution-free air purifier assembly which can purify the part affected by the electric field force in the air to be treated, has simple structure, no secondary pollution, basically no need for maintenance in later period, and low manufacturing cost.

[0004] The technical scheme for solving the above technical problems is as follows: a secondary pollution-free air purifier assembly, comprising a first pipe body, a second pipe body, a metal wire and a first fan; the first pipe body is arranged along the left-right direction, the right end of the first pipe body is a gas inlet, and the left end thereof is a gas outlet, and the first pipe body is grounded through a lead wire; the right end of the second pipe body extends into the first pipe body through the left end of the first pipe body, and there is an annular gap between the second pipe body and the first pipe body, a plurality of first insulating supports are arranged on the outer wall of one end of the second pipe body in the first pipe body and connected with the inner wall of the first pipe body, and a filter screen is mounted on the right end of the second pipe body through an insulator; the metal wire is arranged in the first pipe body along the left-right direction, and the left end thereof is fixedly connected with the filter screen, and the right end thereof is fixedly connected with the inner wall of the first pipe body through a second insulating support with hollow holes, and the metal wire is electrically connected with the negative electrode of a direct-current power supply; the first fan is fixedly installed in the second pipe body and located on the left side of the filter screen, and the air outlet of the first fan faces left, and the air inlet thereof faces right, the first fan is used to suck polluted air into the right end of the first pipe body, and the metal wire is used to ionize the polluted air, so that the part of the polluted air affected by the electric field force is negatively charged and moves to the inner wall of the first pipe body until it is discharged through the left end of the annular gap, and the clean gas after removing dust particles is discharged through the left end of the second pipe body.

[0005] The beneficial effects of the above scheme are: by connecting the metal wire to the negative high voltage of the direct-current power supply and grounding the first pipe body, starting the first fan to work, the polluted air enters from the right end of the first pipe body, the metal wire ionizes the polluted air, the negative charge combines with the dust particles to move to the inner wall of the first pipe body, the charge flows to the ground through the first pipe body, and the dust particles are deposited on the inner wall of the first pipe body and are discharged to the outside through the annular gap by wind power, and the gas after removing the dust particles is delivered to the room or the place needing purification through the second pipe body. The polluted air and the clean air are discharged separately. Because the filter screen is connected with the negatively charged metal wire, the filter screen itself is also negatively charged, and the negatively charged filter screen discharges the small amount of dust particles that have not passed through the inner wall of the first pipe body to the surrounding annular gap under the repulsion of the electric field force, further improving the purification rate. At the same time, through the arrangement of the first insulating support, the second insulating support and the insulator, the safety of the device can be ensured. The scheme can continuously clean the air, the treated polluted air is discharged to the outside, the maintenance work is simple, no consumables need to be replaced, and it is suitable for some use scenarios that need continuous work and cannot be phased and have large size.

[0006] Further, the filter screen is a metal screen.

[0007] The beneficial effect of the further scheme is that: the metal mesh is connected to the negative pole of the direct current power supply together with the metal wire, and the polluted air is charged and ionized, so that the dust particles in the polluted air at the right end of the second tube body are combined with the electric charge and move to the inner wall of the first tube body, and are discharged through the annular gap, thereby reducing the dust particles accumulated on the filter mesh, and further blocking the dust particles from entering the second tube body.

[0008] Further, the mesh number of the filter mesh is 60-400 meshes.

[0009] The beneficial effect of the further scheme is that: the mesh number of the filter mesh is 60-400 meshes, which can effectively block the dust particles from being discharged together with the purified gas through the second tube body.

[0010] Further, a second fan is installed at the right side of the first tube body inside the second insulating support, and the air inlet of the second fan faces right, and the air outlet faces left.

[0011] The beneficial effect of the further scheme is that: the second fan is installed at the gas inlet of the first tube body, which can increase the wind power and improve the flow speed of the air, thereby improving the air purification efficiency.

[0012] The beneficial effect of the present application is that: the polluted air is ionized by connecting the metal wire to the negative high voltage of the direct current power supply and grounding the first tube body, so that the ionized electric charge collides with the dust particles and moves to the inner wall of the first tube body during the movement, and is discharged through the annular gap along with the air flow, thereby achieving good dust removal effect. At the same time, the dust particles accumulated on the filter mesh are reduced by the setting of the metal mesh, and the dust particles are further blocked from being discharged together with the purified gas. In addition, the first fan or the second fan can be used alone, or the first fan and the second fan can be used together, so that the device has multiple use options in actual use, and has the advantages of simple structure, reasonable design, continuous and uninterrupted provision of clean air, less maintenance workload in later period, and suitability for use scenarios that require continuous provision of clean air and cannot be interrupted for later maintenance.

[0017] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0018] Example 1

[0019] like Figs. 1-2 As shown, an air purifier assembly without secondary pollution includes a first tube 1, a second tube 2, metal wires 5, and a first fan 6. The first tube 1 is arranged in a left-right direction, with its right end as the gas inlet and its left end as the gas outlet. The first tube 1 is grounded via a wire. The right end of the second tube 2 extends into the first tube 1 through the left end of the first tube 1, and there is an annular gap between the second tube 2 and the first tube 1. Multiple circumferentially spaced first insulating supports 3 are provided on the outer wall of the end of the second tube 2 inside the first tube 1 and are connected to the inner wall of the first tube 1. A filter screen 4 is installed on the right end of the second tube 2. The metal wires 5 are arranged in a left-right direction. Inside the first tube 1, its left end is fixedly connected to the filter screen 4, and its right end is fixed to the inner wall of the first tube 1 through a hollow second insulating bracket 7. The metal wire 5 is used to connect to the negative terminal of the DC power supply. The first fan 6 is fixedly installed inside the second tube 2 and is located to the left of the filter screen 4. The air outlet of the first fan 6 faces left and its air inlet faces right. The first fan 6 is used to draw polluted air through the right end of the first tube 1. The metal wire 5 is used to ionize the polluted air so that the part of the polluted air affected by the electric field becomes negatively charged and moves to the inner wall of the first tube 1 until it is discharged through the left end of the annular gap. The clean gas after removing dust particles is discharged through the left end of the second tube 2.

[0020] In this embodiment, the metal wire 5 is connected to the negative high voltage of the DC power supply, and the first tube 1 is grounded. This activates the first fan 6, drawing polluted air into the first tube 1 from the right end. The metal wire 5 ionizes the polluted air, and the charge combines with dust particles, causing them to move towards the inner wall of the first tube 1. The charge flows through the first tube 1 towards the ground, while the dust particles are deposited on the inner wall of the first tube 1 and discharged through the annular gap by the airflow. The air, now free of dust, is then transported to the room or other areas requiring purification via the second tube 2. The filter 4 prevents untreated polluted air flowing towards the right end of the second tube 2 from being discharged along with the purified air, thus achieving separate discharge of polluted and purified air. Furthermore, the first insulating support 3, the second insulating support 7, and the insulator ensure the safety of the device and prevent the risk of electric shock.

[0021] Preferably, in this embodiment, the insulator is an annular insulator, which can effectively mount the filter screen 4 at the right end of the second tube 2.

[0022] Further, the filter screen 4 can be installed inside or at the right end of the second tube body 2 through the circular ring-shaped insulator.

[0023] The filter screen 4 is a metal screen. The metal screen 4 is connected to the negative pole of a direct current power source together with the metal wire 5 to ionize the polluted air, so that the dust particles in the polluted air at the right end of the second tube body 2 are moved to the inner wall of the first tube body 1 by the electric charge and are discharged through the annular gap, thereby reducing the dust particles accumulated on the filter screen 4 and effectively further blocking the dust particles from entering the second tube body 2.

[0024] The filter screen 4 has a mesh number of 60-400 meshes. The filter screen 4 having a mesh number of 60-400 meshes can effectively block the dust particles from being discharged together with the purified gas through the second tube body 2.

[0025] The second fan 8 is installed at the right side of the second tube body 1 and has an air inlet facing right and an air outlet facing left. The second fan 8 is installed at the gas inlet of the first tube body 1 to increase the wind power and the flow speed of the air, thereby improving the air purification efficiency and moving the dust particles deposited on the inner wall of the first tube body 1 along the inner wall of the first tube body 1 and discharging the dust particles through the annular gap under the action of the wind power of the second fan 8.

[0026] Preferably, the filter screen 4 has a mesh number of 60-120 meshes. The filter screen 4 having a mesh number of 60-120 meshes can effectively block the dust particles after the first fan 6 and the second fan 8 are started, thereby improving the quality of the gas discharged through the second tube body 2.

[0027] The working process is described as follows: the left end of the second tube body 2 is connected to the indoor environment or is connected to the indoor environment through a gas conveying pipe, and the first fan 6 or the second fan 8 is started or both the first fan 6 and the second fan 8 are started to work, the polluted air enters from the right end of the first tube body 1, the metal wire 5 ionizes the polluted air, the dust particles are moved to the inner wall of the first tube body 1 by the electric charge, the electric charge flows to the ground through the first tube body 1, the dust particles are deposited on the inner wall of the first tube body 1 and are discharged to the outside through the annular gap by the wind power, and the gas after the dust particles are removed is conveyed to the indoor environment or a place that needs to be purified through the second tube body 2, so that the polluted air and the clean air are discharged separately. Since the filter screen 4 is connected to the negatively charged metal wire 5, the filter screen 4 itself is also negatively charged, and the small amount of dust particles that do not pass through the inner wall of the first tube body 1 are discharged to the surrounding annular gap under the repulsion of the electric field force, thereby further improving the purification rate.
