DETAILED DESCRIPTION

[0037] ​To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0038] Example 1

[0039] like Figures 1 to 12 As shown, this is the first embodiment of the present invention. This embodiment provides an outdoor vertical circular layered stacked air conditioning system, including a housing 10, with air inlets 11 at both ends of the housing 10. Inside the housing 10 are two units 12, upper and lower. A filter cylinder 13 is fixedly connected to one end of each unit 12 near the air inlet 11. An air regulating mechanism 20 is located inside the air inlet 11 and is used to adjust the air intake area and air volume. The air regulating mechanism 20 includes an inner cylinder 21 rotatably mounted on the outside of the filter cylinder 13. The inner cylinder 21 has several first air inlets 211. A filter cylinder 13 is rotatably mounted on the outside of the inner cylinder 21. The outer cylinder 22 has several second air inlets 221, and the number of first air inlets 211 and second air inlets 221 is equal. The cleaning mechanism 30 is located on the outside of the filter cylinder 13 and is used to clean impurities on the filter cylinder 13. The cleaning mechanism 30 includes several cleaning arms 31 fixedly connected to the inside of the inner cylinder 21. Brush heads 32 are fixedly connected to the cleaning arms 31 and are in contact with the outer surface of the filter cylinder 13. A water collection tank 33 is installed on the top of the housing 10. The water collection tank 33 and the brush heads 32 are connected to the cleaning arms 31. A debris collection component 34 is provided below the cleaning arms 31.

[0040] It should be noted that the filter cylinder 13 has several filter holes arranged circumferentially inside for circular air intake. The diameter of the filter holes is smaller than the diameter of the impurities, which is used to prevent impurities from entering the interior of the filter cylinder 13. In the initial state, there is no overlap between the first air intake hole 211 and the second air intake hole 221.

[0041] The application is used, in the initial state, no overlapping part between the first air inlet hole 211 and the second air inlet hole 221, hindering the outdoor fresh air from passing through the air adjusting mechanism 20 to the inside of the filter screen cylinder 13, facilitating the closing of the air inlet when the air conditioning system does not need air inlet, compared with the conventional air inlet 11 always open mode, reducing the case that impurities pass through the air inlet 11 and adhere to the filter screen cylinder 13 when air inlet is not needed, when air inlet is needed, the inner cylinder 21 rotates to drive the outer cylinder 22 to rotate together, the rotation speed of the inner cylinder 21 increases, the tangential force tangent to the rotation track drives the outer cylinder 22 to rotate reversely relative to the inner cylinder 21, so that the outer cylinder 22 and the inner cylinder 21 are staggered, the first air inlet hole 211 and the second air inlet hole 221 are close to each other and overlap, the outdoor fresh air passes through the overlapping gap between the first air inlet hole 211 and the second air inlet hole 221 and enters the inside of the filter screen cylinder 13, the greater the rotation speed of the inner cylinder 21, the greater the tangential force, the greater the degree of staggering of the outer cylinder 22 and the inner cylinder 21, and the greater the overlapping area between the first air inlet hole 211 and the second air inlet hole 221, so as to adjust the air inlet area and the air inlet amount by adjusting the rotation speed of the inner cylinder 21, compared with the conventional mode, reducing the case that the fixed air inlet area leads to the difficulty in adjusting the air inlet amount, improving the applicability, and the outer cylinder 22 rotates to drive the cleaning arm 31 and the brush head 32 to rotate along the filter screen cylinder 13, the brush head 32 cleans the impurities adhered to the outer wall of the filter screen cylinder 13, reducing the case that dust and other impurities adhere to the filter screen cylinder 13 to affect the filtering effect of the filter screen cylinder 13, thereby facilitating the cleaning of the filter screen cylinder 13.

[0042] Embodiment 2

[0043] Referring to Figures 1 to 12 , this embodiment is based on the previous embodiment.

[0044] As Figure 4 shown, the top inner side of the filter screen cylinder 13 is fixedly connected with a motor 131, and the output end of the motor 131 is fixedly connected with the top of the inner cylinder 21.

[0045] It should be noted that the rotation speed of the output end of the motor 131 is adjustable, and the adjustment range is for the purpose of driving the inner cylinder 21 and the outer cylinder 22 to stagger, and the speed does not need to be too fast to avoid the case that the rotation of the inner cylinder 21 is too fast to affect the air inlet.

[0046] According to the above structure, the motor 131 works to drive the inner cylinder 21 to rotate, the rotation speed of the output end of the motor 131 is adjusted to adjust the rotation speed of the inner cylinder 21, facilitating the adjustment of the air inlet amount.

[0047] As Figure 5 and Figure 9As shown, the outer wall of the inner cylinder 21 is fixedly connected with a first protrusion 212, the inner wall of the outer cylinder 22 is fixedly connected with a second protrusion 222, and the first protrusion 212 and the second protrusion 222 are connected with a spring 23.

[0048] It should be noted that the outer wall of the inner cylinder 21 is provided with a groove, and the inner wall of the inner cylinder 21 is fixedly connected with an insertion block, which is rotationally matched with the groove, and the inner cylinder 21 and the outer cylinder 22 are rotationally installed together through the matching of the insertion block and the groove.

[0049] According to the above structure, in the initial state when the inner cylinder 21 is not rotated, the distance between the first protrusion 212 and the second protrusion 222 remains relatively fixed under the elastic action of the spring 23, so that the relative position between the inner cylinder 21 and the outer cylinder 22 remains fixed, at this time, there is no overlapping part between the first air inlet hole 211 and the second air inlet hole 221, which facilitates impeding external impurities from passing through the air inlet 11 and adhering to the filter screen cylinder 13. When the inner cylinder 21 rotates, the spring 23 is connected between the first protrusion 212 and the second protrusion 222, so that the inner cylinder 21 drives the outer cylinder 22 to rotate together. When the rotation speed of the inner cylinder 21 increases, the tangential force in the tangential direction of the rotation track resists the elastic action of the spring 23, so that the second protrusion 222 approaches the first protrusion 212, thereby causing the outer cylinder 22 to be offset in the opposite direction relative to the inner cylinder 21, the first air inlet hole 211 and the second air inlet hole 221 approach each other, and an overlapping part appears between the first air inlet hole 211 and the second air inlet hole 221. The outdoor fresh air enters the inside of the filter screen cylinder 13 through the overlapping part. The faster the rotation speed of the inner cylinder 21, the greater the tangential force, and the smaller the distance between the second protrusion 222 and the first protrusion 212, so that the overlapping part between the first air inlet hole 211 and the second air inlet hole 221 is also larger. The centrifugal force outward along the radius direction of rotation away from the rotation center causes the outer cylinder 22 to move away from the inner cylinder 21, so that a small gap is generated between the inner wall of the outer cylinder 22 and the outer wall of the inner cylinder 21, which facilitates reducing the friction between the inner cylinder 21 and the outer cylinder 22, so as to facilitate the offset between the inner cylinder 21 and the outer cylinder 22. The faster the rotation speed of the inner cylinder 21, the greater the centrifugal force, and the greater the gap between the outer cylinder 22 and the inner cylinder 21, so that the friction between the inner cylinder 21 and the outer cylinder 22 is smaller. Thus, by adjusting the rotation speed of the inner cylinder 21, the distance between the outer cylinder 22 and the inner cylinder 21 is adjusted, the area of the overlapping part between the first air inlet hole 211 and the second air inlet hole 221 is adjusted, and then the air inlet area and the air inlet amount are adjusted. When the inner cylinder 21 stops rotating, the spring 23 pushes the second protrusion 222 away from the first protrusion 212 under the elastic action, so as to facilitate the resetting of the first air inlet hole 211 and the second air inlet hole 221.

[0050] As Figure 5 and Figure 9As shown, the inside of the spring 23 is provided with a sliding rod 24, one end of the sliding rod 24 is in sliding connection with the first protrusion 212, and the other end of the sliding rod 24 is in fixed connection with the second protrusion 222.

[0051] It should be noted that the inside of the first protrusion 212 is provided with a sliding hole, and the sliding hole is in sliding cooperation with the sliding rod 24.

[0052] According to the above structure, the sliding rod 24 is arranged in the inside of the spring 23, which reduces the situation that the middle part of the spring 23 drops when the overall length of the spring 23 is relatively long, and improves the reliability of the spring 23.

[0053] As shown in Figure 9 and Figure 10 The cleaning arm 31 is provided with a heating rod 35, and the heating rod 35 is in fixed connection with the cleaning arm 31.

[0054] It should be noted that the heating rod 35 is a prior art, which converts electrical energy into heat energy through resistance heating effect, and then heats objects or media, which will not be described here.

[0055] According to the above structure, after the inner cylinder 21 rotates, the cleaning arm 31 and the heating rod 35 are driven to rotate along the outer wall of the filter screen cylinder 13. After the heating rod 35 works, heat is generated, which evaporates the water remaining on the outer wall of the filter screen cylinder 13, so as to reduce the influence of the water remaining on the outer wall of the filter screen cylinder 13 on the incoming air after the spring 23 is cleaned.

[0056] As shown in Figure 4 The water collecting tank 33 is in rotary connection with the top of the shell 10, the bottom of the water collecting tank 33 is connected with the electromagnetic valve 36, and the plurality of cleaning arms 31 are in communication with the electromagnetic valve 36.

[0057] It should be noted that the bottom of the water collecting tank 33 is in fixed connection with the output end of the motor 131, which is used to rotate the water collecting tank 33 together with the inner cylinder 21, so that the water collecting tank 33 rotates together with the cleaning arm 31, and the water in the water collecting tank 33 flows into the cleaning arm 31, the electromagnetic valve 36 is a prior art, which is used to connect or block the flow of water in the pipeline, which will not be described here, the top of the water collecting tank 33 is designed as an open type, the source of the water in the water collecting tank 33 can be artificially added or collected from the outdoor rainwater through the open top, and the inside of the water collecting tank 33 is fixedly connected with a first filter plate for filtering impurities mixed in the rainwater.

[0058] According to the above structure, after the electromagnetic valve 36 is opened, the water in the water collecting tank 33 is used to wet the brush head 32 through the cleaning arm 31, which reduces the dust generated when the brush head 32 cleans the filter screen cylinder 13, and facilitates the cleaning of the outer wall of the filter screen cylinder 13 by the brush head 32.

[0059] As shown in Figure 5 ,Figure 6 、 Figure 9 and Figure 10 As shown in

[0060] As shown in Figure 5 、 Figure 6 and Figure 10 The inside of the cleaning arm 31 is vertically provided with a plurality of wetting holes 312, one end of the wetting hole 312 is communicated with the water flow channel 311, and the other end of the wetting hole 312 is communicated with the brush head 32.

[0061] It should be noted that the brush head 32 is made of water-absorbing material.

[0062] According to the above structure, when the water in the water collecting tank 33 flows through the cleaning arm 31, on the one hand, the brush head 32 is wetted through the wetting hole 312, which facilitates the cleaning of the filter screen cylinder 13 by the brush head 32, and on the other hand, the water flows into the impurity collecting assembly 34 through the bottom of the cleaning arm 31, which facilitates the collection of impurities by the impurity collecting assembly 34.

[0063] As shown in Figure 4 、 Figure 6 and Figure 11 The impurity collecting assembly 34 includes an impurity collecting groove 341 arranged below the cleaning arm 31, the impurity collecting groove 341 is fixedly connected with the outer wall of the machine body 12, and the outer side of the shell 10 is fixedly connected with a collecting box 342, which is communicated with the impurity collecting groove 341.

[0064] It should be noted that the bottom inside of the impurity collecting groove 341 is inclined towards the side close to the collecting box 342, which is used to move the impurities in the impurity collecting groove 341 to the collecting box 342 for collection, the inside of the collecting box 342 is provided with a second filter plate for filtering and collecting impurities, and the bottom of the collecting box 342 is provided with a drain port for draining water in the collecting box 342.

[0065] According to the above structure, after the brush head 32 cleans the filter screen cylinder 13, the impurities fall into the impurity collecting groove 341, and the water in the water collecting tank 33 flows into the impurity collecting groove 341 through the cleaning arm 31, so that the water in the impurity collecting groove 341 is moved to the collecting box 342 for collection.

When the two units (12) need to be used in parallel, the second air valve (18) is closed to disconnect the ventilation pipe (17), and the air supply ports (14) of both units (12) are opened, allowing both units (12) to draw in fresh outdoor air and supply it to the room through the air supply pipe, thus achieving parallel use. At this time, one unit (12) can be closed as needed to save energy. 12) After a malfunction, the other unit (12) can continue to work, improving reliability. When it is necessary to use the two units (12) in series, close the air outlet (14) of the upper unit (12), open the air outlet (14) of the lower unit (12), and open the second air valve (18) to connect the air outlet (14) of the upper unit (12) with the lower unit (12), so that the gas sent out by the upper unit (12) is used as the gas drawn in by the lower unit (12), thereby realizing series use, which facilitates the heat balance between the two units (12), reduces the overload of the units (12), and facilitates the improvement of the stability and reliability of the air conditioning system. Thus, after the two units (12) are stacked, they can not only be used in parallel, but also in series.
