Description

Technical Field

[0001] This application relates to the field of dust removal, and more specifically, to a gas treatment device. Background Technology

[0002] Gas handling equipment refers to devices capable of heating, cooling, and dehumidifying gases, such as air conditioners and air purifiers. Because gas handling equipment needs to process gases, it is equipped with air inlets. To prevent dust from entering the equipment through the air inlets during daily use, baffles are usually installed at the air inlets to block dust.

[0003] However, in actual use, it has been found that if the equipment is not used for a long time or is in a dusty environment, a lot of dust will accumulate on the baffle. When the equipment is started and the baffle detaches from the air inlet, a large amount of dust on the baffle will fall into the equipment and cause contamination. Summary of the Invention

[0079] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0080] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0081] According to the embodiments of this application, an embodiment of a gas processing apparatus and method is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0082] like Figure 1 As shown, the gas handling equipment has an air inlet 100, and its interior is equipped with a dust removal structure. The dust removal structure includes:

[0083] First track 3, second track 4, and third track 5;

[0084] The first track 3 and the second track 4 are used to correspond to the air inlet 100 of the gas processing equipment, and the second track 4 is set away from the air inlet 100 relative to the first track 3; the third track 5 is located on the same side in the extension direction of the first track 3 and the second track 4, and the third track 5 is connected to both the first track 3 and the second track 4.

[0085] Filter element 1 and baffle 2;

[0086] The filter element 1 can move along the first track 3 and reciprocate between the first track 3 and the third track 5 through the position where the first track 3 communicates with the third track 5; when the filter element 1 moves to the first track 3 and corresponds to the air inlet 100, it blocks the air inlet 100.

[0087] The baffle 2 can move along the second track 4 and reciprocate between the second track 4 and the third track 5 through the position where the second track 4 communicates with the third track 5; when the baffle 2 moves to the second track 4 and corresponds to the air inlet 100, it blocks the air inlet 100.

[0088] Dust removal component 8;

[0089] The dust removal assembly 8 is located on the reciprocating movement path of the filter element 1 between the first track 3 and the third track 5 and / or on the reciprocating movement path of the baffle 2 between the second track 4 and the third track 5. The dust removal assembly 8 is used to remove dust from the filter element 1 and / or the baffle 2.

[0090] In one embodiment, the gas handling device can be an air conditioner or an air purifier, which has an air inlet 100 and an air outlet. Outside air enters the gas handling device through the air inlet 100, passes through the interior of the gas handling device, and flows into the room through the air outlet. The gas handling device is capable of processing the airflow, such as refrigeration by the evaporator and sterilization by the purifier, etc., which are not specifically limited in this embodiment.

[0091] The gas handling equipment forms a gas flow path from the air inlet 100 to the air outlet. A dust removal structure is installed inside the gas handling equipment, with both the first track 3 and the second track 4 positioned along this gas flow path. Specifically, since the second track 4 is located on the side of the first track 3 furthest from the air inlet 100, the gas first passes through the air inlet 100, and then sequentially passes through the first track 3 and the second track 4. It should also be noted that because the filter element 1 and the baffle 2 are subjected to dust removal by the dust removal assembly 8 as they move towards the third track 5, the third track 5 may not be positioned within the gas flow path to avoid secondary pollution from the dust after dust removal.

[0092] In one embodiment, the filter element 1 includes a filtering state and a temporary storage state, and the baffle 2 includes a state of blocking the air inlet 100 and a temporary storage state. The filtering state refers to the filter element 1 filtering the gas entering through the air inlet 100, at which point the filter element 1 is located at a position corresponding to the air inlet 100. The temporary storage state refers to the filter element 1 moving to a position away from the air inlet 100 and no longer filtering the gas entering through the air inlet 100. The state of blocking the air inlet 100 refers to the baffle 2 blocking or collecting dust at the air inlet 100, at which point the baffle 2 is located at a position corresponding to the air inlet 100, making it difficult for dust at the air inlet 100 to enter the gas processing equipment. The temporary storage state refers to the baffle 2 moving to a position away from the air inlet 100 and no longer blocking or collecting dust at the air inlet 100.

[0093] For ease of understanding, in one embodiment, such as Figure 1 As shown, the air inlet 100 is located on the upper side of the gas handling equipment. The first track 3 and the second track 4 are both horizontally or inclined. The third track 5 is located on one side of the first track 3 and the second track 4 and is vertically arranged, so that the dust processed by the dust removal component 8 falls into the space on one side of the third track 5, avoiding contamination of other parts.

[0094] In one embodiment, the first track 3, the second track 4, and the third track 5 are independent physical components. Taking the first track 3 as an example, it may include two plates connected to the gas processing equipment, with the filter element 1 moving between the two plates. Alternatively, the first track 3 can also be a physical component formed by utilizing the existing structure of the gas processing equipment. For instance, the air inlet 100 of the gas processing equipment may have multiple ribs, originally used to strengthen the housing 102. By changing the position, shape, and / or volume of the ribs, a passage is formed between the ribs, allowing the filter element 1 to move, and the ribs then serve as the first track 3. The second track 4 and the third track 5 are similar and will not be described further.

[0095] The filter element 1 is restricted by the first track 3 and can only move along the first track 3. Similarly, the baffle 2 is restricted by the second track 4 and can only move along the second track 4. When the filter element 1 or the baffle 2 moves into the third track 5, it will be restricted by the third track 5 and can only move along the third track 5. In this embodiment, the first track 3, the second track 4, and the third track 5 are not specifically limited, but are intended to constrain the movement trajectory of the filter element 1 or the baffle 2.

[0096] By setting the first track 3, the second track 4 and the third track 5, the movement path of the filter element 1 and the baffle 2 is fixed during the movement process, and they are not easy to deviate. This helps to improve the movement control effect of the filter element 1 and the baffle 2, and makes it less likely for the filter element 1 and the baffle 2 to collide during the movement process, and also less likely for them to collide with other parts.

[0097] In one embodiment, both the first driving member 6 and the second driving member 7 refer to parts with a driving function, such as a motor or a cylinder; this embodiment does not specifically limit this. The dust removal assembly 8 can remove dust from the filter element 1 and / or the baffle 2 through contact or non-contact methods. Specifically, for example, the dust removal assembly 8 includes a brush-like structure that contacts the filter element 1 and / or the baffle 2 to achieve a dust removal effect. The dust removal assembly 8 includes a blower or a laser emitter, which vibrates the filter element 1 and / or the baffle 2 by blowing air or emitting a beam to achieve a dust removal effect.

[0098] As described above, when the gas treatment equipment is shut down, the baffle 2 can move to the second track 4 to block the air inlet 100, preventing external dust from entering the gas treatment equipment. Simultaneously, the filter can move to the third track 5, where it is cleaned by the dust removal component 8, preventing dust from falling onto other parts inside the gas treatment equipment and thus avoiding contamination. When the gas treatment equipment is turned on, the baffle 2 can move to the third track 5, where it is cleaned by the dust removal component 8 during its movement, preventing dust from falling onto other parts inside the gas treatment equipment and thus avoiding contamination. Simultaneously, the filter moves to the first track 3 to filter the airflow entering the gas treatment equipment through the air inlet 100, ensuring dust filtration.

[0099] In another embodiment of this application, the first track 3 and the second track 4 are spaced apart along the height direction of the gas processing equipment, and the first track 3 and the second track 4 extend along the front-back direction of the gas processing equipment.

[0100] The third track 5 extends along the height of the gas processing equipment and is positioned closer to the front of the gas processing equipment than to the rear.

[0101] The height direction of the gas handling equipment refers to its height direction after installation. Taking an air conditioner as an example, for a wall-mounted air conditioner, after installation, its height direction is vertical, and its front-to-back direction is horizontal. Wall-mounted air conditioners are clearly distinguishable in terms of front and back, so we won't elaborate further. For floor-standing air conditioners, which have a clearly visible base or bottom, they also have a unique height direction during use: vertical and front-to-back. For ease of understanding, we can use... Figure 1 To understand the direction of the gas processing equipment in the process, Figure 1 The vertical direction represents the height of the gas processing equipment, while the horizontal direction represents the front and back of the gas processing equipment. The left side is the front of the gas processing equipment, and the right side is the rear of the gas processing equipment.

[0102] Based on the above, the extension direction of the third track 5 is different from that of the first track 3 and the second track 4. This helps to prevent secondary pollution when removing dust from the filter element 1 and / or the baffle 2. That is, the dust that leaves the filter element 1 and / or the baffle 2 moves to other positions with the airflow in the gas treatment equipment, which helps to improve the dust removal effect.

[0103] In another embodiment of this application, the first track 3 includes a first track segment 31 and a second track segment 32;

[0104] The first track segment 31 is set horizontally, and the second track segment 32 is set at an angle;

[0105] The second orbit 4 includes the third orbit segment 41 and the fourth orbit segment 42;

[0106] The third track section 41 is set horizontally, and the fourth track section 42 is set at an angle;

[0107] The end of the second track segment 32 away from the first track segment 31 is connected to the first position of the third track 5 extending along the height direction of the gas processing equipment, and the end of the fourth track segment 42 away from the third track segment 41 is connected to the second position of the third track 5 extending along the height direction of the gas processing equipment. The first position is higher than the second position.

[0108] Both the second track segment 32 and the fourth track segment 42 are inclined downwards.

[0109] As described above, both the first track 3 and the second track 4 have multiple track segments, which makes the movement of the filter element 1 and the baffle 2 smoother, less prone to jamming or generating large internal stress, and improves the lifespan of the filter element 1 and the baffle 2.

[0110] In another embodiment of this application, such as Figure 2As shown, the second track segment 32 is arc-shaped and convex towards the front of the gas processing equipment, the fourth track segment 42 is arc-shaped and convex towards the front of the gas processing equipment, and the upper part of the third track 5 includes a first arc-shaped segment 51, which convex towards the rear of the gas processing equipment.

[0111] Or, such as Figure 3 As shown, the third track 5 includes at least a second arc segment 52 and a third arc segment 53 from top to bottom. The second arc segment 52 and the third arc segment 53 are connected. The second arc segment 52 protrudes towards the front side of the gas processing equipment, and the third arc segment 53 protrudes towards the rear side of the gas processing equipment.

[0112] Based on the above, by setting the arc segment, the filter element 1 and the baffle 2 are less likely to generate large stress when entering the third track 5, which helps to improve the service life of the filter element 1 and the baffle 2.

[0113] In another embodiment of this application, the gas processing equipment includes a housing 102 and a heat exchanger 104; both the dust removal structure and the heat exchanger 104 are located inside the housing 102.

[0114] The air inlet 100 is located on the upper side of the housing 102. The first track 3 and the second track 4 are both located above the heat exchanger 104 and below the air inlet 100. The third track 5 is located on the side of the heat exchanger 104 near the front of the gas processing equipment.

[0115] Among them, heat exchanger 104 is an indoor heat exchanger 104.

[0116] By setting the first track 3 and the second track 4 between the air inlet 100 and the heat exchanger 104, and setting the third track 5 between the front of the gas processing equipment and the heat exchanger 104, the internal space of the gas processing equipment is fully utilized, making it less likely for the space occupied by the gas processing equipment to increase.

[0117] In another embodiment of this application, the dust removal structure includes a first driving member 6 and a second driving member 7, wherein the first driving member 6 is used to drive the filter element 1 to move, and the second driving member 7 is used to drive the baffle 2 to move.

[0118] The first driving member 6 and the second driving member 7 are designed to generate power to move the filter element 1 and the baffle 2. This embodiment does not limit the specific structure of the first driving member 6 and the second driving member 7. For example, the first driving member 6 and the second driving member 7 can be a motor or a cylinder.

[0119] Based on the above, the dust removal structure includes a first driving component 6 and a second driving component 7, which facilitates the driving of the filter component 1 and the baffle 2, thereby improving convenience.

[0120] In another embodiment of this application, the filter element 1 is provided with a first toothed structure, and the first driving element 6 includes a first driver and a first gear. The first driver is used to drive the first gear to rotate, and the first gear is used to mesh with the first toothed structure to drive the filter element 1 to move.

[0121] The baffle 2 is provided with a second toothed structure, and the second driving member 7 includes a second driver and a second gear. The second driver is used to drive the second gear to rotate, and the second gear is used to mesh with the second toothed structure to drive the baffle 2 to move.

[0122] In one embodiment, the first toothed structure and the second toothed structure, such as a rack, drive the filter element 1 and the baffle 2 through the meshing of the rack and the gear.

[0123] In one embodiment, the first driving member 6 further includes a first roller shaft, with gears at both ends. One gear is used to connect to the output shaft of the first driver, and the other gear is a first gear used to mesh with a first toothed structure. Furthermore, a reduction gearbox can be installed between the output shaft of the first driver and the gears to improve the driving stability of the first driver.

[0124] Similarly, the second driving component 7 may also include a second roller shaft, with gears provided at both ends of the second roller shaft, one of which is a second gear, which will not be described in detail here.

[0125] In one embodiment, the first driver and the second driver can be a motor or a rotary cylinder, and this embodiment does not specifically limit them.

[0126] Through the above, by setting the first toothed structure and the second toothed structure, the filter element 1 and the baffle 2 are driven by the meshing connection, which helps to improve the movement stability of the filter element 1 and the baffle 2.

[0127] In another embodiment of this application, the dust removal assembly 8 includes a dust removal brush 81 for contacting the filter element 1 to remove dust from the filter element 1, and / or for contacting the baffle 2 to remove dust from the baffle 2.

[0128] The dust removal brush 81 is positioned on the moving path of the filter element 1 and corresponds to the position of the first track 3, so that the filter element 1, when at least partially moved onto the first track 3 and without obstructing the air inlet 100, comes into contact with the dust removal brush 81.

[0129] Alternatively, the dust removal brush 81 is positioned on the moving path of the baffle 2 and corresponds to the position of the second track 4, so that the baffle 2, when at least partially moved onto the second track 4 and without obstructing the air inlet 100, comes into contact with the dust removal brush 81.

[0130] Alternatively, the position of the dust removal brush 81 corresponds to the third track 5, so that the dust removal brush 81 is located on the common moving path of the filter element 1 and the baffle 2, so that the filter element 1 and the baffle 2 are at least partially moved onto the third track 5 and do not block the air inlet 100 when they come into contact with the dust removal brush 81.

[0131] In one embodiment, the dust removal brush 81 includes a plurality of bristles, which clean the filter element 1 and the baffle 2 by contacting the bristles with the filter element 1 and the baffle 2, and remove dust from the filter element 1 and the baffle 2.

[0132] In one embodiment, a single dust-removing brush 81 can be provided, which only contacts the filter element 1 to remove dust from it. The dust on the baffle 2 falls off naturally due to gravity. This helps reduce the number of parts, the space occupied by the dust removal structure, and lower costs. In another embodiment, two dust-removing brushes 81 can be provided, one for contacting the filter element 1 and the other for contacting the baffle 2, ensuring the dust removal effect of the baffle 2.

[0133] Based on the above, the dust removal component 8 includes a dust removal brush 81, which cleans the filter element 1 and / or baffle 2 by contact. This ensures the dust removal effect and prevents the dust that falls after processing from gaining a large amount of kinetic energy, thus avoiding the dust from contaminating other parts again.

[0134] In another embodiment of this application, the dust removal assembly 8 further includes a third driving member, which is connected to the dust removal brush 81 and is used to rotate the dust removal brush 81 to a first preset position or a second preset position, wherein the dust removal brush 81 can contact the filter element 1 and / or the baffle 2 when it is in the first preset position.

[0135] The dust removal structure also includes a cleaning component 9, which is disposed on one side of the dust removal brush 81. When the dust removal brush 81 is in the second preset position, it contacts the cleaning component 9.

[0136] In one embodiment, the third driving component can be a motor or cylinder, or other component with a driving function; this embodiment does not specifically limit this. The output shaft of the third driving component is connected to the dust removal brush 81, enabling the dust removal brush 81 to rotate, thus placing the dust removal brush 81 in a first preset position and a second preset position. For ease of understanding, as... Figure 1 As shown, the dust removal brush 81 can also be set to a third preset position, in which the dust removal brush 81 faces downwards. Figure 4 As shown, the dust removal brush 81 is located in a first preset position for contacting the filter element 1 to remove dust from it. Figure 5 As shown, the dust removal brush 81 is located in the second preset position and is used to contact the cleaning component 9 so that the cleaning component 9 can clean the dust removal brush 81 and remove the dust or debris adhering to the dust removal brush 81.

[0137] In one embodiment, the cleaning component 9 is used to clean the dust removal brush 81. The cleaning component 9 is, for example, a bristle or a brush, and is intended to be able to clean the dust removal brush 81. This embodiment does not specifically limit this.

[0138] Through the above, by setting a third driving component, the position of the dust removal brush 81 is changed so that when the dust removal brush 81 does not need to remove dust, it can be located in the second preset position, reducing unnecessary contact between the dust removal brush 81 and the filter screen and / or baffle 2, and extending the service life of the dust removal brush 81.

[0139] In another embodiment of this application, the dust removal structure further includes a dust collection box 10, which is disposed on the outer periphery of the third track 5. The dust collection box 10 is used to collect dust generated when the dust removal assembly 8 removes dust from the filter element 1 and / or the baffle 2.

[0140] In one embodiment, the dust collection box 10 is detachably connected to the gas processing equipment, making it convenient for the user to clean the dust in the dust collection box 10.

[0141] In one embodiment, the dust collection box 10 is located below the cleaning component 9 to facilitate the collection of dust or debris that falls onto the cleaning component 9.

[0142] As described above, by setting up the dust collection box 10, dust can be collected, preventing dust from falling onto other parts and improving the dust removal effect.

[0143] In another embodiment of this application, the dust removal structure further includes a detection component for detecting the position of the filter element 1 and the position of the baffle 2, and outputting a position signal based on the position of the filter element 1 and the position of the baffle 2.

[0144] In one embodiment, the detection component is used to detect the position of the filter element 1 and the baffle 2, and can output a position signal to facilitate the identification of the real-time position of the filter element 1 and the baffle 2 when controlling the movement of the filter element 1 and the baffle 2, thereby avoiding collisions between the filter element 1 and the baffle 2 during the movement and improving the stability of the movement control of the filter element 1 and the baffle 2.

[0145] In another embodiment of this application, the detection component includes a first sensor 11, a second sensor 12, a third sensor 13, and a fourth sensor 14; the position signal includes a first position signal, a second position signal, a third position signal, a fourth position signal, a fifth position signal, a sixth position signal, a seventh position signal, and an eighth position signal.

[0146] The first sensor 11 is located at one end of the first track 3 and the third track 5, and is used to output a first position signal when the filter element 1 is detected, and to output a second position signal when the filter element 1 is not detected.

[0147] The second sensor 12 is located at the end of the first track 3 away from the first sensor 11, and is used to output a third position signal when the filter element 1 is detected, and to output a fourth position signal when the filter element 1 is not detected.

[0148] When filter 1 moves from the third track 5 to the first track 3, filter 1 first passes the first sensor 11 and then passes the second sensor 12.

[0149] The third sensor 13 is located at one end of the second track 4 and the third track 5, and is used to output a fifth position signal when the baffle 2 is detected, and to output a sixth position signal when the baffle 2 is not detected.

[0150] The fourth sensor 14 is located at the end of the second track 4 away from the third sensor 13, and is used to output a seventh position signal when the baffle 2 is detected, and to output an eighth position signal when the baffle 2 is not detected.

[0151] When the baffle 2 moves from the third track 5 to the second track 4, the baffle 2 first passes the third sensor 13 and then the fourth sensor 14.

[0152] In one embodiment, such as Figure 7 As shown, the sensor includes a receiver and a transmitter. Taking the first sensor 11 as an example, the first sensor 11 includes a first receiver 112 and a first transmitter 111. The distance between the first receiver 112 and the first transmitter 111 is s. The position of the filter and the baffle 2 is determined by detecting whether there is any obstruction within the range of the distance s. The second sensor 12, the third sensor 13, and the fourth sensor 14 can have the same structure and setting as the first sensor 11.

[0153] Based on the above, the use of sensors to detect the positions of filter element 1 and baffle 2 has high accuracy and can easily improve the control stability during the movement of filter element 1 and baffle 2.

[0154] In one embodiment, the filter element 1 is a filter screen.

[0155] In one embodiment, the gas handling equipment includes a wall-mounted air conditioning indoor unit.

[0156] To make it easier to understand, let's take an air conditioner as an example. When the air conditioner is turned off, such as Figure 1 As shown, filter 1 is located in the third track 5, and baffle 2 is located in the second track 4. Baffle 2 is used to block dust entering through air inlet 100, and the filter is located inside the air conditioner, making it less susceptible to dust contamination.

[0157] When the air conditioner is turned on, such as Figure 4 As shown, the filter element 1 is located in the first track 3 and the baffle 2 is located in the third track 5, so that the air inlet 100 can enter the air normally, and the incoming air will be filtered by the filter element 1 to ensure that dust does not easily enter the air conditioner.

[0158] When it is necessary to clean filter element 1, such as Figure 5 As shown, the third driving member rotates the dust removal brush 81 to the first preset position, and the filter element 1 moves from the third track 5 to the first track 3, or from the first track 3 to the third track 5, during which it can contact the dust removal brush 81 to obtain dust removal treatment.

[0159] When the dust removal brush 81 needs cleaning, such as Figure 6 As shown, the third driving member rotates the dust removal brush 81 to the second preset position, so that the dust removal brush 81 comes into contact with the cleaning member 9.

[0160] This embodiment also provides a dust removal method for a gas treatment device, including:

[0161] When removing dust from filter element 1, control baffle 2 is fully positioned on the second track 4, and control filter element 1 to move between the first track 3 and the third track 5.

[0162] And / or, when removing dust from the baffle 2, control the baffle 2 to move between the second track 4 and the third track 5, and control the filter element 1 to be located in a position that does not obstruct the movement of the baffle 2 between the second track 4 and the third track 5;

[0163] When removing dust from the filter element 1 and / or the baffle 2, the dust removal assembly 8 comes into contact with the filter element 1 and / or the baffle 2.

[0164] In one embodiment, when the gas processing equipment is powered on, that is, when it starts up, the current executing entity sends a control command to the first driving component 6, causing the first driving component 6 to move the filter component 1 from the third track 5 to the first track 3. The gas processing equipment being powered on can be considered as starting up, and the gas processing equipment activating a certain function can also be considered as starting up; this embodiment does not specifically limit this.

[0165] The current execution entity can be a control chip in the gas processing equipment, or it can be a controller independent of the gas processing equipment, such as a remote control. This embodiment does not specifically limit this.

[0166] It should be noted that, in order to protect the filter element 1 and prevent dust contamination inside the gas handling equipment, when the gas handling equipment is turned off, the baffle 2 is located in the second track 4 to block the air inlet 100, which helps to reduce the entry of external dust into the gas handling equipment. At the same time, the filter element 1 is located in the third track 5 and is protected.

[0167] In one embodiment, after the first driving member 6 has been started for a period of time or after the first driving member 6 has been braked, the second driving member 7 drives the baffle 2 to move into the third track 5 to prevent the baffle 2 and the filter member 1 from interfering with each other and colliding.

[0168] As described above, the filter element 1 is closer to the air inlet 100, making the filter element 1 less prone to damage. Furthermore, when the gas processing equipment is started, the dust accumulated on the baffle 2 is less likely to contaminate the internal parts of the gas processing equipment, but is instead removed in the third track 5.

[0169] In another embodiment of this application, the dust removal structure includes a detection component, which is used to detect the position of the filter element 1 and the position of the baffle 2, and output a position signal according to the position of the filter element 1 and the position of the baffle 2.

[0170] The method also includes:

[0171] Based on the position signals output by the detection component for filter element 1 and baffle 2, the positions of filter element 1 and baffle 2 are determined, and the movement or braking of at least one of filter element 1 and baffle 2 is controlled based on the positions of filter element 1 and baffle 2.

[0172] In one embodiment, the detection component includes a first sensor 11 and a second sensor 12. Both the first sensor 11 and the second sensor 12 include a transmitter and a receiver. When the first receiver 112 of the first sensor 11 cannot receive the signal from the first transmitter 111 of the first sensor 11, it outputs a first flag; when the first receiver 112 receives the signal from the first transmitter 111, it outputs a second flag. Similarly, when the second receiver of the second sensor 12 cannot receive the signal from the second transmitter of the second sensor 12, it outputs a third flag; when the second receiver receives the signal from the second transmitter, it outputs a fourth flag. The inability to receive a signal indicates the presence of an obstacle between the transmitter and receiver, obstructing signal transmission. Therefore, it proves that the filter 1 or the baffle 2 is located between the receiver and the transmitter, thus revealing the positions of the filter 1 and the baffle 2.

[0173] Through the above, by installing sensors and receiving sensor detection signals, the position of filter element 1 is identified, thereby controlling the driving and braking of the first driving element 6, which helps to improve the movement control accuracy of filter element 1.

[0174] In another embodiment of this application, the detection component further includes a third sensor 13 and a fourth sensor 14. The third sensor 13 and the fourth sensor 14 are similar to the first sensor 11 and the second sensor 12, and are used to determine the position of the baffle 2. The specific principle is the same as that of the first sensor 11 and the second sensor 12, and will not be repeated here.

[0175] As described above, the movement control process of baffle 2 is also detected by sensors, which improves the movement control accuracy of baffle 2 and makes it less likely for filter element 1 to collide with baffle 2 when they move.

[0176] This application also provides a control method for a gas treatment device, the gas treatment device having the above-mentioned dust removal structure, the method comprising:

[0177] In response to a shutdown signal for the gas handling equipment, the control baffle 2 moves to the second track 4 and corresponds to the air inlet 100 to block the air inlet 100, and the control filter 1 moves to the third track 5.

[0178] And / or, in response to the power-on signal for the gas handling equipment, control the filter element 1 to move onto the first track 3 and correspond to the air inlet 100 to block the air inlet 100, and control the baffle 2 to move onto the third track 5.

[0179] That is, when the machine is turned off, the air inlet 100 is blocked by the baffle 2, and when the machine is turned on, the air inlet 100 is blocked by the filter element 1. In the process of controlling the movement of the baffle 2 and the filter element 1, the filter element 1 or the baffle 2 on the third track 5 should be moved first to avoid interference between the filter element 1 and the baffle 2.
