[0046] The double-effect cleaning and purification device 1000 for air-conditioning ducts according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0047] Reference Figure 1 , Figure 2 and Figure 3 As shown, the air conditioning duct double-effect cleaning and purification device 1000 provided according to the embodiment of the utility model comprises a cleaning cylinder 10, a large particle dust guide funnel 20, an ion generator 30 and an ion tube 40;

[0048] The side walls of the clean cylinder 10 are oppositely provided with an air inlet 101 and an air outlet 102, and the bottom of the clean cylinder 10 is formed to be open; the inner diameter of the large-particle dust guide funnel 20 gradually decreases from top to bottom, and the upper edge of the large-particle dust guide funnel 20 is connected to the open edge of the bottom of the clean cylinder 10 to form a whole;

[0049] Furthermore, the ion generator 30 is fixed outside the clean cylinder 10 ; the ion tube 40 is fixed vertically or obliquely inside the clean cylinder 10 and is located between the air inlet 101 and the air outlet 102 , and is electrically connected to the ion generator 30 .

[0050] Based on the above, it can be clearly seen that when the present application is implemented, it is mainly used as a dual-effect cleaning and purification device 1000 for air conditioning ducts.

[0051] Specifically, when applying the present application, when it is necessary to purify the air in the laminar flow wards of major hospitals, community health centers, medical clinics and other medical institutions, the air outlet 102 is connected to the air inlet of the air purification equipment (such as air conditioning equipment, etc.) that needs to be used in conjunction with it, and then, the present application is fixed so that the large-particle dust diversion funnel 20 is located at the bottom, and the ion generator 30 is started. In this way, the present application can be easily used.

[0052] The working principle of the present application when in use is mainly as follows: when the gas containing polluted dust enters the clean cylinder 10 through the air inlet 101, due to the difference in inertia between large dust particles and gas during movement, the greater the mass, the greater the inertia, and the greater the gravity. After the two collide with the surface of the ion tube 40, the flow direction will change sharply, and the large dust particles will flow into the large dust diversion funnel 20 due to their own gravity to separate the two. When they pass through the surface of the ion tube 40, the present application uses the set voltage principle to work, and triggers discharge through the inner / outer electrodes of the ion tube 40 to generate ion clusters similar to those in nature. These millions of charged ion clusters actively collide with harmful substances such as bacteria and viruses in the gas containing polluted dust flowing through the surface of the ion tube 40, so that they can penetrate cell membranes, DNA and proteins, so that the bacteria and viruses in the gas containing polluted dust flowing through the surface of the ion tube 40 can be quickly broken and lose their activity until they are killed and decomposed. In this way, clean gas can be obtained and discharged from the air outlet 102.

[0053] The use of the above-mentioned application will obviously have the following technical effects:

[0054] First, the gas containing polluted dust enters the clean cylinder 10 through the air inlet 101, and the large particles of dust will flow into the large particle dust guide funnel 20 due to their own gravity and be collected, so as to be separated from the gas that needs to be discharged, so that the large particles of dust in the gas that needs to be cleaned and purified can be better removed, so that it is not easy to be discharged and flow into the air purification equipment used, so that it is not easy to accelerate the clogging and aging of the filter screen of the air purification equipment used, so that there is basically no need for manual cleaning and maintenance, which can greatly reduce labor costs.

[0055] Second, the gas containing polluted dust enters the clean cylinder 10 through the air inlet 101. When it passes through the surface of the ion tube 40, the present application uses a set voltage to work, and triggers discharge through the inner / outer electrodes of the ion tube 40 to generate ion clusters similar to those in nature. These millions of charged ion clusters actively collide with harmful substances such as bacteria and viruses in the gas containing polluted dust flowing through the surface of the ion tube 40, so that they can break through cell membranes, DNA and proteins, so that the bacteria and viruses in the gas containing polluted dust flowing through the surface of the ion tube 40 can be quickly broken and lose activity until they are killed and decomposed. In this way, clean gas can be obtained and discharged from the air outlet 102, so that primary filtration can be achieved, and then secondary filtration can be performed through the supporting air purification equipment, so that the gas containing polluted dust can be cleaned and purified more comprehensively, so that it basically does not contain harmful substances such as bacteria and viruses when it is finally discharged.

[0056] Furthermore, through the above-mentioned optimized design, the whole formed by the present application can achieve double-effect cleaning and purification of gas containing polluted dust, making it highly practical and having good use effect.

[0057] Furthermore, in the specific implementation, Figure 3 As shown, according to an embodiment of the present invention, a plurality of ion tubes 40 are provided, and the plurality of ion tubes 40 are fixedly arranged in the clean cylinder 10 along an oblique direction, and the lower ends thereof are all directed toward below the air outlet 102 .

[0058] Therefore, when the gas containing polluted dust enters the clean cylinder 10 through the air inlet 101, due to the difference in inertia between large dust particles and gas in motion, the larger the mass, the greater the inertia, and the greater the gravity. After the two collide with the surface of the ion tube 40, the flow direction will be sharply changed. Since the multiple ion tubes 40 are fixed in the clean cylinder 10 along the oblique direction, their lower ends are all facing below the air outlet 102. Therefore, when large dust particles collide with the surfaces of the multiple ion tubes 40 in the horizontal direction, the surfaces of the multiple ion tubes 40 are folded downward, so that the large dust particles can flow into the large dust diversion funnel 20 more quickly through their own inertia and gravity to be collected, so that the large dust separation effect is good when the present application is used in practice.

[0059] Furthermore, in the specific implementation, Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, the plurality of ion tubes 40 are arranged in at least one row, and the connection line between the upper ends of the ion tubes 40 in each row is perpendicular to the connection line between the air inlet 101 and the air outlet 102 .

[0060] Therefore, it is clear that when the gas containing polluted dust enters the clean cylinder 10 through the air inlet 101, it will be intercepted by at least one row of the ion tubes 40 at the first time, so that the area where the gas containing polluted dust is impacted can be greatly increased, so that the large particles of dust can be separated better and the cleaning and purification effect itself can also be better.

[0061] Preferably, in this technical solution, continue to control Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, the plurality of ion tubes 40 are arranged in a plurality of rows, the ion tubes 40 in each row are evenly arranged, the spacing between two adjacent ion tubes 40 in each row is equal to or slightly smaller than the outer diameter of any one of the ion tubes 40, and the ion tubes 40 in each two adjacent rows are staggered.

[0062] Therefore, it is clear that when the plurality of ion tubes 40 are arranged in multiple rows, the ion tubes 40 in each row are evenly arranged, the distance between two adjacent ion tubes 40 in each row is equal to or slightly smaller than the outer diameter of any ion tube 40, and the ion tubes 40 in each adjacent row are staggered, through this optimized design, the area where the gas containing polluted dust is impacted can be greatly increased, so that the gas containing polluted dust flowing through the gap between any two ion tubes 40 can be cleaned and purified, wherein the separation effect of large-particle dust is better, and the cleaning and purification effect itself is also better.

[0063] And preferably, in the present technical solution, the ion tubes 40 are arranged in three rows, so that the present application can achieve multiple first-stage filtration, so that the gas finally discharged from the air outlet 102 has a very high degree of cleanliness and purification.

[0064] In addition, in the specific implementation, Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of the present utility model, a switch valve 50 which can be opened is provided at the bottom of the large particle dust guide funnel 20 .

[0065] Therefore, when the collected large dust particles need to be processed, the switch valve 50 can be opened to transfer the large dust particles collected in the large dust diversion funnel 20 for processing.

[0066] Furthermore, in the specific implementation, continue to compare Figure 1 , Figure 2 and Figure 3 As shown, according to one embodiment of the present utility model, a large particle dust collector 60 is detachably provided at the lower end of the switch valve 50 .

[0067] Therefore, when the collected large-particle dust needs to be processed, the switch valve 50 can be opened to transfer the large-particle dust collected in the large-particle dust diversion funnel 20 to the large-particle dust collector 60 for transit. When the large-particle dust collector 60 is removed to transfer and process the large-particle dust collected therein, during this process, the switch valve 50 can be closed to continue using the present application, so that the present application can be used uninterruptedly, so that the use of the present application is continuous.

[0068] It should be added that in the specific implementation, Figure 1 As shown, according to one embodiment of the utility model, the ion generator 30 is fixedly mounted on the upper end surface of the clean cylinder 10, and is provided with an ion controller connected to the ion tube 40 for controlling the operation of the ion tube 40, and is provided with a power switch 301 and a working indicator light 302 connected to the ion controller.

[0069] For the above-mentioned present application, the ion controller provided in the ion generator 30 is used to control the operation of the ion tube 40, which is an existing mature technology. The present application is only invented by optimizing the structure of the setting position, etc., so as to be applied in the field related to air purification. Therefore, the circuits between the various internal components, etc., are not intended to be described in detail here.

[0070] It is further necessary to add that, in a specific implementation, according to an embodiment of the utility model, a mounting opening is provided in the middle of the upper end surface of the clean cylinder 10, and the periphery of the ion generator 30 is supported by the periphery of the mounting opening and fixed to the mounting opening by fastening bolts and other fasteners. In this way, when the ion generator 30 is disassembled, it is easy to drive the synchronous disassembly of the multiple ion tubes 40 arranged in the clean cylinder, so as to facilitate the maintenance or replacement of the whole.

[0071] And preferably, in the present technical solution, according to an embodiment of the present utility model, the upper edge of the large-particle dust guide funnel 20 is detachably connected to the open edge of the bottom of the clean cylinder 10 .

[0072] Therefore, when the large-particle dust guide funnel 20 and the clean cylinder 10 are detached, it is convenient to maintain the multiple ion tubes 40 fixed in the clean cylinder 10, so that the application is more flexible and convenient to use.

[0073] It should also be added that in the specific implementation, continue to compare Figure 1As shown, according to the double-effect cleaning and purification device 1000 for air-conditioning ducts provided by the embodiment of the utility model, a fault alarm circuit connected between the ion controller and the plurality of ion tubes 40 is further provided in the ion generator 30, and a sound alarm 303 and an alarm cancellation key 304 connected to the ion controller are further provided outside the ion generator 30. In this way, when any of the ion tubes 40 fails or breaks down, the sound alarm 303 can output a sound alarm to remind the user to maintain or replace the corresponding failed or broken ion tube 40, so that the present application is highly reliable to use. At the same time, the user can eliminate the alarm in time by operating the alarm cancellation key 304 to avoid the alarm ringing continuously.

[0074] Other embodiments and the like are not described here by way of example.

[0075] To sum up, in the double-effect cleaning and purification device 1000 for air-conditioning ducts provided in the present application, during specific implementation, large particles of dust flow into the large particle dust diversion funnel 20 due to their own gravity and are collected so as to be separated from the gas to be discharged, so that the large particles of dust in the gas to be cleaned and purified can be better removed, so that it is not easy to be discharged and flow into the air purification equipment used, so that it is not easy to accelerate the clogging and aging of the filter screen of the air purification equipment used, so that basically no manual cleaning and maintenance is required, which can greatly reduce labor costs and other costs.

[0076] Furthermore, the gas containing polluted dust enters the clean cylinder 10 through the air inlet 101. When the gas passes through the surface of the ion tube 40, the present application uses the set voltage principle to work, and triggers discharge through the inner / outer electrodes of the ion tube 40 to generate ion clusters similar to those in nature. These millions of charged ion clusters actively collide with harmful substances such as bacteria and viruses in the gas containing polluted dust flowing through the surface of the ion tube 40, so that they can penetrate cell membranes, DNA and proteins, so that the bacteria and viruses in the gas containing polluted dust flowing through the surface of the ion tube 40 can be quickly broken and lose activity until they are killed and decomposed. In this way, clean gas can be obtained and discharged from the air outlet 102, so that primary filtration can be achieved, and then secondary filtration can be performed through the supporting air purification equipment, so that the gas containing polluted dust can be cleaned and purified more comprehensively, so that it basically does not contain harmful substances such as bacteria and viruses when it is finally discharged.

[0077] Furthermore, the air-conditioning duct dual-effect cleaning and purification device 1000 provided in the present application is indeed extremely practical and has excellent use effect, which makes the present application bound to have a good market promotion value, and the present application is bound to be very popular and will be effectively popularized.
