Description

Technical Field

[0001] This application relates to the field of filter cleaning technology, and in particular to a filter cleaning device. Background Technology

[0002] During daily operation, the pre-filter in a modular air conditioning unit is used for initial filtration, which traps a significant amount of dust. However, once dust accumulates in the pre-filter, it leads to a decrease in airflow and a reduction in cooling and heating efficiency. Therefore, to ensure airflow quality, the pre-filter needs to be cleaned periodically.

[0003] However, in related technologies, the primary filter is mainly washed manually with a handheld high-pressure water gun. However, due to the high labor intensity, the cleaning efficiency of the filter is low. Utility Model Content

[0004] The main objective of this application is to provide a filter cleaning device that enables automatic cleaning of filters, thereby improving the cleaning efficiency of filters.

[0005] To achieve the above objectives, the filter cleaning apparatus proposed in this application includes:

[0006] The conveyor line is configured to convey filters;

[0007] A limiting mechanism is configured to cooperate with the conveyor line to clamp the filter, thereby limiting and fixing the filter to the conveyor line;

[0008] A cleaning mechanism, configured to clean and limit the filter fixed to the conveyor line; and

[0009] The dehydration mechanism, located downstream of the washing mechanism on the conveyor line, is configured as a filter fixed to the conveyor line for drying.

[0010] The filter cleaning device in this application includes a conveyor line and a cleaning mechanism. The conveyor line transports the filter to the cleaning mechanism for cleaning. This achieves automatic cleaning of the filter, enabling continuous operation and improving cleaning efficiency. Furthermore, the filter cleaning device also includes a limiting mechanism that works in conjunction with the conveyor line to clamp and fix the filter to the conveyor line. This improves the stability of the filter's position on the conveyor line, ensuring stable cleaning and enhancing the cleaning effect when the filter is transported to the cleaning mechanism. Simultaneously, the clamping and limiting action of the filter using the limiting mechanism and the conveyor line also utilizes the conveyor line for filter positioning. In this case, the limiting mechanism only needs to limit the filter in certain directions, simplifying its structural design.

[0011] Optionally, the limiting mechanism includes a movable abutment that can move toward and away from the conveyor line, and the movable abutment is configured to cooperate with the conveyor line to clamp the filter.

[0012] Therefore, by adjusting the distance between the movable contact part and the conveyor line, filters of different heights can be installed, thereby improving the applicability of the filter cleaning device to different filters.

[0013] Optionally, the limiting mechanism further includes a limiting drive member, which is connected to the movable abutment member and configured to drive the movable abutment member to move.

[0014] Therefore, by using a limit drive to move the movable abutment, the driving operation process of the movable abutment can be simplified, thereby improving the ease of use of the filter cleaning device.

[0015] Optionally, the filter cleaning device also includes a body, a limit drive component including a lead screw, the lead screw being rotatably inserted through the body, a movable abutment component and a conveyor line being arranged at relative intervals, and the lead screw extending along the arrangement direction of the movable abutment component and the conveyor line;

[0016] The movable abutment is connected to a lead screw, which is configured to move the movable abutment when rotated.

[0017] Therefore, after the movable abutment is slid into place by the rotation of the lead screw, it can self-lock and limit its movement. This eliminates the need for an additional limiting and locking structure for the movable abutment after it slides into place, thus simplifying the structural design of the limiting mechanism.

[0018] Optionally, the movable abutment part is provided with a rotating hole, and the machine body is provided with a threaded hole corresponding to the rotating hole; the lead screw passes through the threaded hole and is rotatably inserted into the rotating hole;

[0019] And / or, the limit drive also includes a handwheel, which is located at the end of the lead screw away from the movable abutment.

[0020] Therefore, by providing threaded holes and rotating holes on the machine body and the movable abutment part respectively, the lead screw can move up and down during rotation. This improves the compactness of the distribution between the limiting mechanism and the conveyor line while meeting the required travel of the movable abutment part, thereby reducing the overall size of the filter cleaning device. Further configuring the limiting drive component to include a handwheel allows the operator to manually drive the lead screw to control the sliding of the movable abutment part, thus improving the human controllability of the movable abutment part's drive.

[0021] Optionally, the movable contact member is provided with a first contact surface, which is configured to cooperate with the conveyor line to clamp the filter, and the first contact surface is a plane;

[0022] And / or, the movable abutment extends along the conveying direction of the conveyor line, and the length of the movable abutment is equal to the length of the conveyor line in the conveying direction.

[0023] Therefore, by setting the first contact surface to a plane, it can be made to fit flush with the upper surface of the filter, thereby improving the clamping and limiting effect on the filter. Setting the length of the movable contact member to be equal to the length of the conveyor line allows for clamping and holding at least one filter on the conveyor line with just one movable contact member. This reduces the number of movable contact members and corresponding limiting mechanisms, simplifying the structural design of the filter cleaning device.

[0024] Optionally, the movable abutment and the conveyor line are arranged at relative intervals. The filter cleaning device also includes a body, and the limiting mechanism also includes two fixed abutment members. The two fixed abutment members are fixed to the body, and the arrangement direction of the two fixed abutment members intersects the conveying direction of the conveyor line and the arrangement direction of the conveyor line and the movable abutment members.

[0025] Two fixed abutment parts are located on both sides of the conveyor line and cooperate to clamp the filter.

[0026] This allows the filter to move only in the left-right direction, which is the conveying direction of the conveyor line. This improves the stability of the filter's position on the conveyor line, enabling stable rinsing laterally.

[0027] Optionally, when the movable abutment is in the state of clamping the filter, in the arrangement direction of the conveyor line and the movable abutment, the distance between the end of the fixed abutment closest to the movable abutment and the conveyor line is smaller than the distance between the movable abutment and the conveyor line.

[0028] And / or, the fixed abutment is provided with a second abutment surface, and the second abutment surface on each fixed abutment is provided at intervals relative to the second abutment surface on another fixed abutment, and the second abutment surface is a plane;

[0029] And / or, the fixed abutment extends along the conveying direction of the conveyor line, and the length of the fixed abutment is equal to the length of the conveyor line in the conveying direction.

[0030] Therefore, by setting the height of the fixed abutment to be less than the distance between the movable abutment and the conveyor line, the front and rear sides of the filter on the conveyor line can be better exposed, allowing the cleaning mechanism located at the front and / or rear of the conveyor line to rinse it. Setting the second abutment surface as a plane allows it to fit smoothly against the front and rear surfaces of the filter, thereby improving the clamping and limiting effect on the filter. Setting the length of the fixed abutment to be equal to the length of the conveyor line allows for clamping at least one filter on the conveyor line using only one fixed abutment on each of the front and rear sides, thus reducing the number of fixed abutments and simplifying the structure of the filter cleaning device.

[0031] Optionally, the cleaning mechanism includes a cleaning module, which includes:

[0032] The cleaning pipe is equipped with water spray holes.

[0033] A first control valve, located on the cleaning pipe and configured to control the opening and closing of the cleaning pipe, is positioned upstream of the water spray nozzle in the cleaning pipe; and

[0034] The first position sensor is electrically connected to the first control valve and is configured to detect whether the filter has been delivered to the correct position.

[0035] Therefore, when the first position sensor detects that the filter has been delivered to the location of the cleaning module, it can control the first control valve to open the flow path of the cleaning pipe, so as to realize the timely and automatic start of the cleaning module's cleaning operation on the filter, further improving the convenience of using the filter cleaning device. Conversely, after the first position sensor detects that the filter has been delivered past the location of the cleaning module, it can control the first control valve to close the flow path of the cleaning pipe, thereby saving cleaning water consumption and improving the environmental friendliness of the filter cleaning device.

[0036] Optionally, the cleaning module also includes a nozzle connected to a water spray hole.

[0037] Therefore, the easy-cleaning module can spray a high-pressure water stream to powerfully rinse the filters located on the conveyor line, thereby improving the rinsing effect of the filters.

[0038] Optionally, the conveyor line is provided with a conveying surface configured to carry and convey the filter, and a limiting mechanism cooperates with the conveying surface to clamp the filter;

[0039] At least a portion of the cleaning pipe extends along the conveying direction intersecting the conveying surface, and at least two water spray holes are provided along the direction intersecting the conveying surface.

[0040] The number of nozzles is at least two, and each nozzle is connected to a water spray hole.

[0041] Therefore, installing at least two nozzles arranged in the same direction on the cleaning pipe can increase the rinsing coverage of the filter located on the conveyor line, thereby improving the rinsing efficiency and effect of the cleaning module on the filter.

[0042] Optionally, the first positioning sensor is located upstream of the water spray nozzle on the conveyor line;

[0043] And / or, the limiting mechanism includes two fixed abutment members, which are fixedly arranged and located on both sides of the conveyor line where the conveyor line intersects in the conveying direction. The two fixed abutment members cooperate to clamp the filter, and the first position sensor is located on the fixed abutment member.

[0044] And / or, the first position sensor is a proximity sensor.

[0045] Therefore, by positioning the first positioning sensor upstream of the water spray hole, the filter can pass through the sensor first during transport. This improves the timeliness of the opening of the first control valve when the filter passes the water spray hole, allowing for timely initiation of the filter flushing process. Installing the first positioning sensor in the fixed abutment of the limiting mechanism provides a suitable mounting position, thus facilitating the structural design of the filter cleaning device. Furthermore, using the first positioning sensor as a proximity sensor ensures that it does not come into contact with the filter during transport, preventing any impact on the filter's transport or wear.

[0046] Optionally, the number of cleaning modules is at least two, and the at least two cleaning modules are arranged along the conveying direction of the conveyor line.

[0047] Therefore, setting the number of cleaning modules to at least two facilitates continuous rinsing of the filter during the filter transport process, thereby improving the rinsing effect of the filter.

[0048] Optionally, the cleaning system may also include:

[0049] Water tank;

[0050] The manifold connects the water tank and the individual cleaning pipes in at least two cleaning modules; and

[0051] A first liquid drive unit is disposed in the manifold and configured to drive water in the water tank through the manifold to the cleaning pipe.

[0052] This allows each cleaning module to share a single first liquid drive unit, reducing the number of first liquid drive units required and thus simplifying the structure of the filter cleaning device.

[0053] Optionally, there are two cleaning units, located on opposite sides of the conveyor line where they intersect in the conveying direction.

[0054] Therefore, by using two cleaning mechanisms, the front and rear sides of the filter located on the conveyor line can be rinsed simultaneously, which helps to improve the rinsing efficiency and effect of the filter.

[0055] Optionally, the filter cleaning device also includes a dewatering mechanism located downstream of the cleaning mechanism on the conveyor line, which is configured to dry and limit the filter fixed on the conveyor line.

[0056] This enhances the functionality of the filter cleaning device, enabling automatic drying and dehydration of the filter after cleaning.

[0057] Optionally, the dehydration mechanism includes a dehydration module, which includes...

[0058] Air blowing pipe, the air blowing pipe is equipped with air blowing holes;

[0059] A second control valve, located in the air blowing pipe and configured to control the opening and closing of the air blowing pipe, is positioned upstream of the air blowing orifice in the air blowing pipe; and

[0060] A second position sensor, electrically connected to a second control valve, is configured to detect whether the filter has been delivered to the correct position.

[0061] Therefore, when the second position sensor detects that the filter has been delivered to the location of the dehydration module, it can control the second control valve to open the air blowing pipe, so as to realize the timely and automatic start of the dehydration module's drying operation on the filter, further improving the convenience of using the filter cleaning device. Conversely, after the second position sensor detects that the filter has been delivered past the location of the dehydration module, it can control the second control valve to close the air blowing pipe, thereby saving energy and further improving the environmental friendliness of the filter cleaning device.

[0062] Optionally, the dehydration module also includes a flow guide shroud, which is connected to the air blowing hole and is flared in the direction of air passage of the air blowing hole.

[0063] Therefore, by setting a guide shroud at the air blowing hole, the airflow blown out of the air blowing hole can be guided to increase the air blowing coverage of the filter, which in turn helps to improve the drying efficiency and effect of the dehydration module on the filter.

[0064] Optionally, the conveyor line is provided with a conveying surface configured to carry and convey the filter, and a limiting mechanism cooperates with the conveying surface to clamp the filter;

[0065] At least a portion of the air blowing pipe extends along the conveying direction intersecting the conveying surface, and at least two air blowing holes are provided along the direction intersecting the conveying surface;

[0066] The number of deflectors is at least two, and each deflector is connected to an air inlet.

[0067] This allows for a further increase in the air blowing coverage of the filters located on the conveyor line, which in turn helps to further improve the drying efficiency and effectiveness of the dehydration module for the filters.

[0068] Optionally, the second position sensor is located upstream of the conveyor line relative to the air inlet;

[0069] And / or, the limiting mechanism includes two fixed abutment members, which are fixedly arranged and located on both sides of the conveyor line where the conveyor line intersects in the conveying direction. The two fixed abutment members cooperate to clamp the filter, and the second position sensor is located on the fixed abutment member.

[0070] And / or, the second position sensor is a proximity sensor.

[0071] Therefore, positioning the second position sensor upstream of the air outlet allows the filter to pass through it first during transport. This improves the timeliness of the second control valve opening when the filter passes the air outlet, facilitating timely start-up of the filter drying process. Installing the second position sensor in the fixed abutment of the limiting mechanism provides a suitable mounting position, thus facilitating the structural design of the filter cleaning device. Furthermore, using the second position sensor as a proximity sensor ensures it does not contact the filter during transport, preventing any impact on the filter's transport or wear.

[0072] Optionally, the number of dehydration modules is at least two, and the at least two dehydration modules are arranged along the conveying direction of the conveyor line.

[0073] Therefore, setting the number of dehydration modules to at least two facilitates continuous air blowing on the filter during the filter transport process, thereby improving the drying effect of the filter.

[0074] Optionally, the dehydration mechanism also includes:

[0075] airflow drive components; and

[0076] A connecting pipe connects the airflow drive and each of the blowing pipes in at least two dehydration modules, the airflow drive being configured to drive airflow through the connecting pipe to the blowing pipe.

[0077] This allows each dewatering module to share a single airflow drive, reducing the number of airflow drive components required and thus simplifying the structure of the filter cleaning device.

[0078] Optionally, there are two dehydration units, located on opposite sides of the conveyor line where the conveyor line intersects in the conveying direction.

[0079] Therefore, by using two dehydration mechanisms, air can be blown onto both sides of the filter located on the conveyor line at the same time, which helps to improve the drying efficiency and effect of the filter.

[0080] Optionally, the filter cleaning device also includes a body, which has an installation cavity, and at least part of the conveyor line, the limiting mechanism, and the cleaning mechanism are all located in the installation cavity;

[0081] The machine body has an inlet and an outlet at both ends of the corresponding conveying direction of the conveyor line, and both the inlet and outlet are connected to the mounting cavity.

[0082] Therefore, by accommodating the movable contact parts, fixed contact parts, and lead screws in the conveyor line, cleaning mechanism, dewatering mechanism, and limiting mechanism through the mounting cavity of the machine body, this provides isolation and protection for these parts of the mechanism, thus reducing the possibility of damage. Simultaneously, it allows for the collection of wastewater after filter cleaning, preventing operators from getting wet during filter cleaning.

[0083] Optionally, the unit body is also provided with a drain port communicating with the installation cavity, and the filter cleaning device further includes a collection mechanism, which includes:

[0084] Collection box;

[0085] Drain pipe, the drain pipe connects to the drain outlet and the collection box; and

[0086] The second liquid drive is located in the drain pipe and is configured to drive the water in the mounting cavity to flow through the drain outlet and the drain pipe to the collection tank.

[0087] Therefore, the wastewater generated during the filter cleaning process inside the installation cavity can be discharged and collected in an organized manner, which facilitates the centralized treatment of the wastewater and prevents pollution to the surrounding environment of the filter cleaning device.

[0101] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0102] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0103] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0104] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0105] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0106] A pre-filter, also known as a primary filter, performs the initial filtration of airflow in the filtration path. Its filtration is primarily physical, mainly intercepting and filtering dust particles trapped in the airflow. Therefore, pre-filters are prone to dust accumulation during use. This dust accumulation can lead to a decrease in airflow and reduced cooling and heating efficiency in equipment using the pre-filter, such as modular air conditioning units. Therefore, to ensure the air delivery quality of equipment using pre-filters, they need to be cleaned periodically.

[0107] However, in related technologies, the primary filter is mainly washed manually with a handheld high-pressure water gun. However, due to the high labor intensity, the cleaning efficiency of the filter is low.

[0108] Therefore, based on the above considerations, in order to solve the problem of low cleaning efficiency caused by high labor intensity in filter cleaning in related technologies, this application proposes a novel filter cleaning device. This filter cleaning device innovatively incorporates a conveyor line, a limiting mechanism, and a cleaning mechanism. The limiting mechanism and the conveyor line work together to clamp the filter, ensuring stable transport of the filter to the cleaning mechanism. The cleaning mechanism then automatically cleans the filter on the conveyor line, improving the cleaning efficiency.

[0109] Furthermore, it should be noted that the filter cleaning device proposed in this application can be used to clean pre-filters, or it can be used to clean medium-efficiency filters. The specific type of filter can be a plate filter as described above, or it can be a Class G filter, a cartridge filter, a nylon mesh filter, or other types of filters. In other words, the type of filter targeted by the filter cleaning device proposed in this application is not limited.

[0110] The structure of the filter cleaning device proposed in this application will be explained and illustrated below with examples:

[0111] Please refer to the reference. Figures 1 to 6 In one embodiment of this application, the filter cleaning device 100 proposed in this application includes a conveyor line 10, a limiting mechanism 20, and a cleaning mechanism 30; the conveyor line 10 is configured to convey the filter 300; the limiting mechanism 20 is configured to cooperate with the conveyor line 10 to clamp the filter 300 so that the filter 300 is limited and fixed on the conveyor line 10; the cleaning mechanism 30 is configured to clean the filter 300 that is limited and fixed on the conveyor line 10.

[0112] The conveyor line 10 is used to transport the filters 300 that need to be cleaned to the cleaning mechanism 30. The conveyor line 10 can transport one filter 300 at a time, or it can transport two or more filters 300 simultaneously. Furthermore, the conveyor line 10 can include a drive wheel, a driven wheel, and a conveyor belt fitted onto the drive wheel and driven wheel to employ a belt conveying method; alternatively, the conveyor line 10 can include multiple conveying rollers to employ a roller conveying method. This application does not limit the structural type of the conveyor line 10, as long as it can transport the filters 300. Additionally, the conveyor line 10 can be mounted on the machine body 40 as described below, or it can be placed directly on the ground.

[0113] The limiting mechanism 20 can be used to cooperate with the conveyor line 10 to clamp the filter 300, so that the filter 300 can be stably installed on the conveyor line 10, thereby improving the stability of the conveying of the filter 300 and its stability during the subsequent cleaning process. Specifically, when the conveyor line 10 includes a drive wheel, a driven wheel, and a conveyor belt fitted onto the drive wheel and driven wheel as described above, the limiting mechanism 20 can cooperate with the conveyor belt to clamp the filter 300. When the conveyor line 10 includes multiple conveyor rollers as described above, the limiting mechanism 20 can cooperate with the conveyor rollers to clamp the filter 300. Therefore, it can be said that the limiting mechanism 20 cooperates with the components in the conveyor line 10 used to carry and convey the filter 300 to clamp the filter 300. Furthermore, the limiting mechanism 20 can include a movable abutment member 21 that is opposite to the movable abutment member 21 and can move closer to or away from the conveyor line 10, as described below. Alternatively, the movable abutment member 21 can be fixed; this application does not limit the structural type of the limiting mechanism 20. In addition, the limiting mechanism 20 can be installed on the body 40 as described below, or it can be placed directly on the ground.

[0114] The cleaning mechanism 30 is used to rinse the filter 300 installed on the conveyor line 10. The cleaning mechanism 30 may include a cleaning pipe 311, as described below, to spray water onto the filter 300 through spray holes 312 on the cleaning pipe 311; alternatively, the cleaning mechanism 30 may include a water tank 32, to spray water onto the filter 300 through spray holes 312 on the water tank 32; or, the cleaning mechanism 30 may include a water supply structure and a cloth, with the cloth being wetted by the water supply structure and then used to clean the filter 300. Therefore, this application does not limit the structural type of the cleaning mechanism 30. Furthermore, the cleaning mechanism 30 may be installed on the machine body 40 as described below, or it may be placed directly on the ground. In addition, when the filter cleaning device 100 is in normal operating condition, the conveyor line 10 may extend horizontally, for example, conveying the filter 300 in a left-right direction. At this time, the cleaning mechanism 30 can be set on at least one side of the conveyor line 10 in the front-back direction, or it can be set above the conveyor line 10. This application does not limit the setting position of the cleaning mechanism 30, as long as it can be used to rinse the filter 300 located on the conveyor line 10.

[0115] The filter cleaning device 100 in this application includes a conveyor line 10 and a cleaning mechanism 30. The filter 300 is conveyed to the cleaning mechanism 30 via the conveyor line 10, where it is cleaned. This achieves automatic cleaning of the filter 300 by the filter cleaning device 100, enabling continuous operation and improving cleaning efficiency. Furthermore, the filter cleaning device 100 also includes a limiting mechanism 20, which works in conjunction with the conveyor line 10 to clamp and fix the filter 300 to the conveyor line. This improves the stability of the filter 300 at the upper limit of the conveyor line 10, ensuring stable cleaning when the filter 300 is conveyed to the cleaning mechanism 300, thus improving the cleaning effect. Simultaneously, the clamping and limiting action of the filter 300 by the limiting mechanism 20 and the conveyor line 10 also utilizes the conveyor line 10 to limit the position of the filter 300. At this time, the limiting mechanism 20 can limit the filter 300 only in some directions, thereby simplifying the structural design of the limiting mechanism 20.

[0116] Please refer to the reference. Figures 4 to 6 In one embodiment of this application, the limiting mechanism 20 includes a movable abutment 21 that is movable in directions toward and away from the conveyor line 10 and is configured to cooperate with the conveyor line 10 to clamp the filter 300.

[0117] The movable abutment 21 is a movable abutment. The movable abutment 21 can slide to move closer to and away from the conveyor line 10. Alternatively, it can rotate to move closer to and away from the conveyor line 10. Therefore, when the conveyor line 10 conveys the filter 300 in a left-right direction as described above, the movable abutment 21 can be positioned above the conveyor line 10 and can slide vertically. Alternatively, the movable abutment 21 can be positioned in front of and / or behind the conveyor line 10 and can rotate about an axis parallel to the left-right direction. Furthermore, the movable abutment 21 can be driven to move by the limiting drive 22 described below. Alternatively, the movable abutment 21 can be movably mounted on the body 40 described below and locked in place by screws or pins after movement. In addition, the movable contact 21 can be a flat plate structure, a block structure, or a U-shaped cover structure, etc., as long as it can cooperate with the conveyor line 10 to clamp the filter 300.

[0118] In this embodiment, the limiting mechanism 20 is configured to include a movable abutment 21, so that the distance between the movable abutment 21 and the conveyor line 10 can be adjusted to accommodate filters 300 of different heights, thereby improving the applicability of the filter cleaning device 100 to different filters 300.

[0119] Please refer to the reference. Figures 4 to 6 In one embodiment of this application, the limiting mechanism 20 further includes a limiting drive member 22, which is connected to the movable abutment member 21 and configured to drive the movable abutment member 21 to move.

[0120] The limiting drive component 22 can be used to provide power to drive the movable abutment component 21 to move. The limiting drive component 22 can be, as described below, a lead screw 221, or a cylinder. This application does not limit the structural type of the limiting drive component 22.

[0121] In this embodiment, the movable abutment 21 is moved by the limiting drive member 22, which simplifies the driving operation process of the movable abutment 21 and thus improves the ease of use of the filter cleaning device 100.

[0122] Please refer to the reference. Figures 4 to 6 In one embodiment of this application, the filter cleaning device 100 further includes a body 40, and a limiting drive member 22 includes a lead screw 221, which is rotatably disposed in the body 40. The movable abutment member 21 and the conveyor line 10 are arranged at relative intervals, and the lead screw 221 extends along the arrangement direction of the movable abutment member 21 and the conveyor line 10. The movable abutment member 21 is connected to the lead screw 221, and the lead screw 221 is configured to drive the movable abutment member 21 to move when rotating.

[0123] The body 40 can be a box structure, with the conveyor line 10, limiting mechanism 20, and cleaning mechanism 30 installed through the inner mounting cavity 42 as described below. Alternatively, the body 40 can be an L-shaped structure, with the limiting drive member 22 installed through a portion at an angle, while the other portion can be placed on the ground. This application does not limit the structural type of the body 40, as long as it can at least be used to install the lead screw 221. Furthermore, the movable abutment member 21 can be positioned above the conveyor line 10, allowing the lead screw 221 to extend vertically. Additionally, the lead screw 221 can be installed on the body 40 via a threaded connection through the threaded hole 41 as described below, achieving a circumferentially rotatable and axially sliding configuration on the body 40. In this case, the lead screw 221 and the movable abutment member 21 can be installed via a circumferentially rotatable and axially limited configuration through the rotating hole 211 as described below. Of course, the screw 221 can be mounted on the body 40 in a circumferentially rotatable and axially limited configuration, while the screw 221 and the movable abutment 21 can be mounted in a circumferentially rotatable and axially sliding configuration. Furthermore, the limit drive 22 can further include a motor to enable the filter cleaning device 100 to automatically drive the screw 221 to rotate. Alternatively, the limit drive 22 can also further include a handwheel 223, as described below, for the operator to manually drive the screw 221 to rotate. Or, the operator can directly hold the screw 221 to drive its rotation.

[0124] In this embodiment, the limiting drive component 22 is configured to include a lead screw 221, so that after the movable abutment component 21 is slid into place by the rotation of the lead screw 221, the movable abutment component 21 can self-lock and limit its movement. This eliminates the need for an additional limiting and locking structure for the movable abutment component 21 after it slides into place, thus simplifying the structural design of the limiting mechanism 20. Simultaneously, since the lead screw 221 transmission has the advantages of stability and low noise, it can also improve the smoothness of the sliding of the movable abutment component 21 and reduce the noise during operation of the filter cleaning device 100.

[0125] Please refer to the reference. Figures 4 to 6 In one embodiment of this application, the movable abutment 21 is provided with a rotating hole 211, and the machine body 40 is provided with a threaded hole 41 corresponding to the rotating hole 211; the lead screw 221 passes through the threaded hole 41 and is rotatably inserted into the rotating hole 211.

[0126] The rotating hole 211 can be used for axially limiting and circumferentially rotatable connection with one end of the lead screw 221. A bearing can be installed within the rotating hole 211, and the lead screw 221 can be inserted into the bearing to establish the connection between the lead screw 221 and the movable abutment 21. Alternatively, the portion of the lead screw 221 inserted into the rotating hole 211 can be a smooth rod, meaning its side circumferential surface does not have a threaded section. Furthermore, an annular rib is provided on one of the smooth rod section and the hole wall of the rotating hole 211, and an annular groove is provided on the other. Both the annular rib and the annular groove are arranged circumferentially around the lead screw 221, with the annular rib housed within the annular groove to establish the connection between the lead screw 221 and the movable abutment 21.

[0127] In this embodiment, threaded holes 41 and rotating holes 211 are respectively provided on the body 40 and the movable abutment 21, so that the lead screw 221 can move up and down during rotation. This improves the compactness of the distribution between the limiting mechanism 20 and the conveyor line 10 while meeting the required travel of the movable abutment 21, thereby reducing the overall volume of the filter cleaning device 100. Of course, when the installation of the lead screw 221 on the body 40 is configured to be circumferentially rotatable and axially limited, and the installation of the lead screw 221 and the movable abutment 21 is configured to be circumferentially rotatable and axially slidable, as described above, the rotating hole 211 can also be provided on the body 40, and a connecting cylinder can be protruded on the side of the movable abutment 21 facing away from the side used to abut and hold the filter 300, and the threaded hole 41 can be provided inside the connecting cylinder.

[0128] Please refer to the reference. Figure 5 and Figure 6 In one embodiment of this application, the limiting drive member 22 further includes a handwheel 223, which is located at the end of the lead screw 221 away from the movable abutment member 21.

[0129] The handwheel 223 provides a gripping position for the operator to hold. The handwheel 223 may include a handwheel body and a grip lever. The handwheel body may be connected to the end of the lead screw 221 away from the movable abutment 21, and the grip lever may protrude from the side of the handwheel body facing away from the movable abutment 21. Alternatively, the handwheel 223 may consist only of the handwheel body. Furthermore, the handwheel body may be formed by a tube or a plate structure; this application does not limit the structural type of the handwheel body. The shape of the handwheel body may be circular or square (the square described in this application includes squares or rectangles); this application does not limit the shape of the handwheel body.

[0130] In this embodiment, the limiting drive component 22 is further configured to include a handwheel 223, which facilitates the operator to manually drive the lead screw 221 to rotate in order to control the sliding of the movable abutment component 21, thereby improving the human controllability of driving the movable abutment component 21.

[0131] Please refer to the reference. Figure 5 and Figure 6 In one embodiment of this application, the movable contact member 21 is provided with a first contact surface 212, which is configured to cooperate with the conveyor line 10 to clamp the filter 300. The first contact surface 212 is a plane.

[0132] When the movable abutment 21 is positioned above the conveyor line 10 as described above, the first abutment surface 212 can be the lower surface of the movable abutment 21.

[0133] In this embodiment, the first contact surface 212 is set as a plane so that it can fit flatly with the upper surface of the filter 300, thereby improving the clamping and limiting effect on the filter 300.

[0134] Please refer to Figure 6 In one embodiment of this application, the movable abutment 21 extends along the conveying direction of the conveyor line 10, and the length of the movable abutment 21 is equal to the length of the conveyor line 10 in the conveying direction of the conveyor line 10.

[0135] When the conveyor line 10 is extended in the left-right direction as described above, it can be said that the projected length of the movable abutment 21 in the left-right direction is equal to the projected length of the conveyor line 10 in the left-right direction.

[0136] In this embodiment, the length of the movable abutment 21 is set to be equal to the length of the conveyor line 10, so that one movable abutment 21 can clamp at least one filter 300 located on the conveyor line 10. This reduces the number of movable abutments 21 and corresponding limiting mechanisms 20, simplifying the structure of the filter cleaning device 100. Simultaneously, this configuration eliminates the need for the movable abutment 21 to be slidable in the left-right direction while still satisfying the clamping and limiting of the filter 300 throughout the conveying process on the conveyor line 10, further simplifying the structure of the filter cleaning device 100. Of course, this application is not limited to this. In other embodiments, the length of the movable abutment 21 can be set to be less than the length of the conveyor line 10. In this case, at least two sets of movable abutments 21 and limiting drive members 22 can be provided in the extension direction of the conveyor line 10. Alternatively, the movable abutment 21 and limiting drive members 22 can be set as one set, with the limiting drive members 22 configured to slide along the extension direction of the conveyor line 10. At this time, a mounting block that can slide along the conveying direction of the conveyor line 10 can be provided on the body 40, and the limiting drive component 22 can be installed on the mounting block. The sliding of the mounting block can be driven by the friction between the movable abutment component 21 and the filter 300. Of course, the mounting block can also be driven by an additional structure such as a pneumatic rod or a linear module.

[0137] Please refer to the reference. Figures 4 to 6 In one embodiment of this application, the movable abutment 21 and the conveyor line 10 are arranged at intervals relative to each other. The limiting mechanism 20 also includes two fixed abutment members 23, which are fixed to the machine body 40. The arrangement direction of the two fixed abutment members 23 intersects the conveying direction of the conveyor line 10 and the arrangement direction of the conveyor line 10 and the movable abutment member 21. The two fixed abutment members 23 are located on both sides of the conveyor line 10 and cooperate to clamp the filter 300.

[0138] When the conveyor line 10 extends in the left-right direction as described above, the movable abutment 21 and the conveyor line 10 can be arranged relatively spaced in the up-down direction, while the two fixed abutment members 23 can be arranged on the front and rear sides of the conveyor line 10. The fixed abutment member 23 can be a plate structure, or it can be a block or column structure. This application does not limit the structural type of the fixed abutment member 23.

[0139] In this embodiment, the filter 300 can be limited in the vertical direction by the movable abutment 21 and the conveyor line 10, while the filter 300 can be limited in the front-back direction by the two fixed abutment members 23. This ensures that the filter 300 can only move in the left-right direction, that is, the conveying direction of the conveyor line 10, thereby improving the stability of the filter 300's limitation on the conveyor line 10, so as to ensure stable rinsing afterward.

[0140] Please refer to Figure 5 In one embodiment of this application, when the movable abutment 21 is in the state of clamping the filter 300, the distance between the fixed abutment 23 near the end of the movable abutment 21 and the conveyor line 10 in the arrangement direction of the conveyor line 10 and the movable abutment 21 is smaller than the distance between the movable abutment 21 and the conveyor line 10.

[0141] When the conveyor line 10 is extended in the left-right direction as described above, it can also be said that the height of the fixed abutment 23 protruding above the conveyor line 10 is less than the distance between the movable abutment 21 and the conveyor line 10 in the up-down direction.

[0142] In this embodiment, the height of the fixed abutment 23 is set less than the distance between the movable abutment 21 and the conveyor line 10, so that the front and rear sides of the filter 300 located on the conveyor line 10 can be better exposed, allowing the cleaning mechanism 30 located on the front and / or rear side of the conveyor line 10 to rinse it. Simultaneously, this arrangement also allows for a smaller volume of the movable abutment 21, reducing space occupation and manufacturing costs. Of course, in other embodiments, the height of the fixed abutment 23 can also be set equal to the distance between the movable abutment 21 and the conveyor line 10. In this case, clearance holes can be provided on the fixed abutment 23 to allow the cleaning mechanism 300 to rinse the filter 300.

[0143] Please refer to the reference. Figure 5 and Figure 6 In one embodiment of this application, the fixed abutment member 23 is provided with a second abutment surface 231. The second abutment surface 231 on each fixed abutment member 23 and the second abutment surface 231 on another fixed abutment member 23 are arranged at intervals relative to each other. The second abutment surface 231 is a plane.

[0144] The second abutment surface 231 can be the surface of two fixed abutment members 23 facing each other, for clamping and limiting the filter 300 located on the conveyor line 10.

[0145] In this embodiment, the second abutment surface 231 is set as a plane so that it can be flatly attached to the front and rear surfaces of the filter 300, thereby improving the clamping and limiting effect of the filter 300.

[0146] Please refer to Figure 6 In one embodiment of this application, the fixed abutment 23 extends along the conveying direction of the conveyor line 10, and the length of the fixed abutment 23 is equal to the length of the conveyor line 10 in the conveying direction of the conveyor line 10.

[0147] When the conveyor line 10 is extended in the left-right direction as described above, it can be said that the projected length of the fixed abutment 23 in the left-right direction is equal to the projected length of the conveyor line 10 in the left-right direction.

[0148] In this embodiment, the length of the fixed abutment 23 is set to be equal to the length of the conveyor line 10, so that at least one filter 300 located on the conveyor line 10 can be abutted and clamped by using one fixed abutment 23 on each of the front and rear sides. This reduces the number of fixed abutment 23s required, thereby simplifying the structure of the filter cleaning device 100. However, this application is not limited to this. In other embodiments, the length of the fixed abutment 23 can be set to be less than the length of the conveyor line 10. In this case, at least two movable abutment 21 can be provided on each of the front and rear sides of the conveyor line 10 along its extension direction.

[0149] Please refer to the reference. Figures 4 to 7 In one embodiment of this application, the cleaning mechanism 30 includes a cleaning module 31, which includes a cleaning pipe 311, a first control valve 313, and a first position sensor 314. The cleaning pipe 311 is provided with a water spray hole 312. The first control valve 313 is located on the cleaning pipe 311 and is configured to control the opening and closing of the cleaning pipe 311. The first control valve 313 is located upstream of the cleaning pipe 311 relative to the water spray hole 312. The first position sensor 314 is electrically connected to the first control valve 313 and is configured to detect whether the filter 300 is delivered to the correct position.

[0150] The cleaning pipe 311 is used to transport cleaning water. The cleaning pipe 311 can be a rigid pipe for more stable installation of the first control valve 313. The spray nozzles 312 on the cleaning pipe 311 are used to spray cleaning water to clean the filter 300 located on the conveyor line 10. The cleaning water can be sprayed directly from the spray nozzles 312 to rinse the filter 300, or, as described below, a nozzle 315 can be connected to the spray nozzles 312. The first control valve 313 is used to control the opening and closing of the flow path within the cleaning pipe 311, thereby controlling the on / off operation of the water spray rinsing of the filter 300. The first control valve 313 can be an electrically controlled valve for electrical connection with the first position sensor 314. The first position sensor 314 is used to detect whether the filter 300 has been transported to the position of the cleaning module 31. The first position sensor 314 can be a proximity sensor, such as an infrared sensor or an ultrasonic sensor, as described below. Of course, the first position sensor 314 can also be a contact sensor, such as a touch switch or a pressure sensor. Furthermore, the first position sensor 314 and the first control valve 313 can be directly electrically connected. That is, a control board can be installed inside the first control valve 313, and the first position sensor 314 is electrically connected to this control board to transmit the detected position signal to the control board, which then controls the opening and closing of the first control valve 313. Alternatively, both the first position sensor 314 and the first control valve 313 can be electrically connected to the controller of the filter cleaning device 100, thus achieving an indirect electrical connection between the first position sensor 314 and the first control valve 313. In this case, the position signal detected by the first position sensor 314 to the filter 300 can be transmitted to the controller of the filter cleaning device 100, so that the controller controls the opening and closing of the first control valve 313.

[0151] In this embodiment, the cleaning module 31 is configured to include a cleaning pipe 311, a first control valve 313, and a first position sensor 314. When the first position sensor 314 detects that the filter 300 has been delivered to the location of the cleaning module 31, the first control valve 313 can be controlled to open the flow path of the cleaning pipe 311. This allows for timely and automatic activation of the cleaning module 31's cleaning operation on the filter 300, further improving the ease of use of the filter cleaning device 100. Conversely, after the first position sensor 314 detects that the filter 300 has been delivered past the location of the cleaning module 31, the first control valve 313 can be controlled to close the flow path of the cleaning pipe 311, saving cleaning water consumption and improving the environmental friendliness of the filter cleaning device 100.

[0152] Please refer to the reference. Figures 6 to 8In one embodiment of this application, the cleaning module 31 further includes a nozzle 315, which is connected to a water spray hole 312.

[0153] The nozzle 315 may have multiple nozzles on the side used for spraying water.

[0154] In this embodiment, a nozzle 315 is further provided on the cleaning pipe 311 so that the cleaning module 31 can spray a water flow with higher pressure to powerfully rinse the filter 300 located on the conveyor line 10, thereby improving the rinsing effect of the filter 300.

[0155] Please refer to the reference. Figures 6 to 8 In one embodiment of this application, the conveyor line 10 is provided with a conveyor surface 11, which is configured to carry and convey the filter 300. The limiting mechanism 20 cooperates with the conveyor surface 11 to clamp the filter 300. At least a portion of the cleaning pipe 311 extends along the conveying direction intersecting the conveyor surface 11 and is provided with at least two water spray holes 312 along the direction intersecting the conveyor surface 11. The number of nozzles 315 is at least two, and each nozzle 315 is connected to a water spray hole 312.

[0156] When the conveyor line 10 includes a drive wheel, a driven wheel, and a conveyor belt as described above, the conveyor belt can form the conveyor surface 11. When the conveyor line 10 includes multiple conveyor rollers as described above, the multiple conveyor rollers can form the conveyor surface 11. Therefore, when the conveyor line 10 extends in the left-right direction as described above, it can be said that the upper side of the conveyor line 10 has a conveyor surface 11. At least a portion of the cleaning pipe 311 extends in the conveying direction intersecting the conveyor surface 11, or at least a portion of the cleaning pipe 311 extends in the vertical direction, and at least two water spray holes 312 are provided in the vertical direction for corresponding installation of at least two nozzles 315.

[0157] In this embodiment, at least two nozzles 315 arranged along the direction are installed on the cleaning pipe 311, which can increase the rinsing coverage of the filter 300 located on the conveyor line 10, thereby improving the rinsing efficiency and effect of the cleaning module 31 on the filter 300. Specifically, multiple branch pipes can be protruding from the side circumference of the cleaning pipe 311 extending in the vertical direction, with the openings at the ends of the branch pipes forming spray holes 312, thus facilitating the connection of the nozzles 315 to the cleaning pipe. In some embodiments, when no nozzles 315 are provided, the spray holes 312 can be formed directly by opening holes in the side circumference of the cleaning pipe 311.

[0158] Please refer to Figure 6 In one embodiment of this application, the first position sensor 314 is located upstream of the conveyor line 10 relative to the water spray hole 312.

[0159] Upstream, that is, the position that filter 300 passes through first during the process of conveying filter 300 by conveyor line 10.

[0160] In this embodiment, the first position sensor 314 is positioned upstream of the water spray hole 312, so that the filter 300 can pass through the first position sensor 314 first during the conveying process. This helps to improve the timeliness of opening the first control valve 313 when the filter 300 passes through the water spray hole 312, so as to start the flushing operation of the filter 300 in a timely manner.

[0161] Please refer to Figure 6 In one embodiment of this application, the first positioning sensor 314 is disposed in the fixed abutment member 23 of the limiting mechanism 20.

[0162] When the fixed abutment 23 is arranged on both sides of the conveyor line 10 as described above, the first position sensor 314 can be installed on the upper surface of the fixed abutment 23. The installation of the first position sensor 314 on the fixed abutment 23 can be by screw connection, snap connection or adhesive connection, etc. This application does not limit the installation method of the first position sensor 314.

[0163] In this embodiment, the first positioning sensor 314 is installed in the fixed abutment member 23 in the limiting mechanism 20, so that the fixed abutment member 23 can be used to provide an installation position, which is beneficial to the structural design of the filter cleaning device 100. At the same time, it also allows the first positioning sensor 314 to be closer to the filter 300 located on the conveyor line 10, which makes it easier for the first positioning sensor 314 to more accurately detect the delivery position of the filter 300.

[0164] In one embodiment of this application, the first position sensor 314 is a proximity sensor.

[0165] In this embodiment, the first positioning sensor 314 is configured as a proximity sensor so that it will not come into contact with the filter 300 when detecting the positioning of the filter 300, thereby preventing any impact on the delivery of the filter 300 or causing wear.

[0166] Please refer to Figure 6 In one embodiment of this application, the number of cleaning modules 31 is at least two, and the at least two cleaning modules 31 are arranged along the conveying direction of the conveyor line 10.

[0167] When the conveyor line 10 is set to extend in the left-right direction as described above, it can also be said that at least two cleaning modules 31 are arranged in the left-right direction.

[0168] In this embodiment, the number of cleaning modules 31 is set to at least two, which facilitates continuous rinsing of the filter 300 during the conveying process of the filter 300, thereby improving the rinsing effect of the filter 300. At the same time, after the filter 300 is conveyed through each cleaning module 31, the first control valve 313 in the cleaning module 31 can be closed, which helps to save cleaning water resources.

[0169] Additionally, it should be noted that each cleaning module 31 may include only one cleaning pipe 311, or it may include two or more cleaning pipes 311 arranged side by side along the conveyor line 10, and the two or more cleaning pipes 311 may merge and share a first control valve 313.

[0170] Please refer to the reference. Figure 6 and Figure 7 In one embodiment of this application, the cleaning mechanism 30 further includes a water tank 32, a manifold 33, and a first liquid driving member 34; the manifold 33 connects the water tank 32 and each cleaning pipe 311 in at least two cleaning modules 31; the first liquid driving member 34 is disposed on the manifold 33 and configured to drive the water in the water tank 32 to flow through the manifold 33 to the cleaning pipe 311.

[0171] The water tank 32 can be used to store cleaning water. The water tank 32 can be a box structure with an opening, or it can be a structure including a main body and an open box cover that fits over the main body. This application does not limit the structural type of the water tank 32. The shape of the water tank 32 can be square or circular, etc., and this application does not limit the shape of the water tank 32. The manifold 33 can connect to the cleaning pipes 311 in each cleaning module 31. Therefore, a portion of the manifold 33 can extend along the arrangement direction of at least two cleaning modules 31. Simultaneously, the manifold 33 can also connect to the water tank 32, thereby achieving indirect connection between the water tank 32 and the cleaning pipes 311 in each cleaning module 31. The first liquid driving component 34 can be used to provide power to drive the cleaning water in the water tank 32 to the cleaning pipes 311. The first liquid driving component 34 can be a water pump, or it can be a negative pressure tank; this application does not limit the type of the first liquid driving component 34.

[0172] In this embodiment, the water tank 32 can store the cleaning water, thereby reducing the frequency of water supply to the cleaning mechanism 30 and further improving the ease of use of the filter cleaning device 100. The manifold 33 allows each cleaning module 31 to share a single first liquid drive component 34, reducing the number of first liquid drive components 34 and simplifying the structure of the filter cleaning device 100. The first liquid drive component 34 also facilitates the effective formation of the required flow path for the cleaning water.

[0173] Please refer to Figure 4 In one embodiment of this application, there are two cleaning mechanisms 30, which are located on opposite sides of the conveyor line 10 where they intersect in the conveying direction.

[0174] When the conveyor line 10 extends in the left-right direction as described above, the two cleaning mechanisms 30 are respectively located on the front and rear sides of the conveyor line 10, and can be further away from the conveyor line 10 than the fixed abutment 23 in the limiting mechanism 20.

[0175] In this embodiment, a cleaning mechanism 30 is provided on both the front and rear sides of the conveyor line 10, so that the front and rear sides of the filter 300 located on the conveyor line 10 can be rinsed simultaneously by the two cleaning mechanisms 30, which helps to improve the rinsing efficiency and effect of the filter 300.

[0176] Please refer to the reference. Figures 4 to 6 In one embodiment of this application, the filter cleaning device 100 further includes a dehydration mechanism 50, which is located downstream of the cleaning mechanism 30 on the conveyor line 10. The dehydration mechanism 50 is configured to dry and limit the filter 300 fixed on the conveyor line 10.

[0177] The dehydration mechanism 50 is located downstream of the cleaning mechanism 30, meaning that the filter 300 can pass through the cleaning mechanism 30 first and then through the dehydration mechanism 50 during transport. The dehydration mechanism 50 is used to dry and dehydrate the rinsed filter 300. The dehydration mechanism 50 can include an air blowing pipe 511, as described below, to dry the filter 300 by blowing air. Alternatively, the dehydration mechanism 50 can include a drying chamber and heating elements such as heating wires or heating tubes inside the drying chamber to heat and dry the filter 300 passing through the drying chamber. This application does not limit the structural type of the dehydration mechanism 50.

[0178] In this embodiment, a dehydration mechanism 50 is further provided, so that the filter cleaning device 100 can not only clean the filter 300, but also dry and dehydrate the filter 300. This enhances the functionality of the filter cleaning device 100, enabling automatic drying and dehydration of the filter 300 after cleaning.

[0179] Please refer to the reference. Figure 6 , Figure 9 as well as Figure 10 In one embodiment of this application, the dehydration mechanism 50 includes a dehydration module 51, which includes an air blowing pipe 511, a second control valve 513, and a second position sensor 514. The air blowing pipe 511 is provided with an air blowing hole 512. The second control valve 513 is located on the air blowing pipe 511 and is configured to control the opening and closing of the air blowing pipe 511. The second control valve 513 is located upstream of the air blowing pipe 511 relative to the air blowing hole 512. The second position sensor 514 is electrically connected to the second control valve 513 and is configured to detect whether the filter 300 is delivered to the correct position.

[0180] The air blowing pipe 511 can be used to transport gas using water. This air blowing pipe 511 can be a rigid pipe for more stable installation of the second control valve 513. The air blowing hole 512 on the air blowing pipe 511 can be used to blow gas to dry the filter 300 located on the conveyor line 10. This drying can be achieved by directly blowing gas from the air blowing pipe 511 onto the filter 300, or, as described below, by further connecting a flow guide shroud 515 to the air blowing hole 512. The second control valve 513 can be used to control the opening and closing of the flow path within the air blowing pipe 511, thereby controlling the on / off operation of the air blowing drying of the filter 300. This second control valve 513 can be an electrically controlled valve for electrical connection to the second position sensor 514. The second position sensor 514 can be used to detect whether the filter 300 has been conveyed to the location of the dehydration module 51. The second position sensor 514 can be a proximity sensor, such as an infrared sensor or an ultrasonic sensor, as described below. Alternatively, it can be a contact sensor, such as a touch switch or a pressure sensor. Furthermore, the second position sensor 514 and the second control valve 513 can be directly electrically connected. That is, a control board can be installed inside the second control valve 513, and the second position sensor 514 is electrically connected to this control board to transmit the detected position signal to the control board, which then controls the opening and closing of the second control valve 513. Alternatively, both the second position sensor 514 and the second control valve 513 can be electrically connected to the controller of the filter cleaning device 100, thus achieving an indirect electrical connection between them. In this case, the position signal detected by the second position sensor 514 on the filter 300 can be transmitted to the controller of the filter cleaning device 100, so that the controller can control the opening and closing of the second control valve 513.

[0181] In this embodiment, the dehydration module 51 is configured to include an air blowing pipe 511, a second control valve 513, and a second position sensor 514. When the second position sensor 514 detects that the filter 300 has been delivered to the location of the dehydration module 51, the second control valve 513 can be controlled to open the flow path of the air blowing pipe 511. This allows for timely and automatic activation of the drying process of the filter 300 by the dehydration module 51, further improving the ease of use of the filter cleaning device 100. Conversely, after the second position sensor 514 detects that the filter 300 has been delivered past the location of the dehydration module 51, the second control valve 513 can be controlled to close the flow path of the air blowing pipe 511, saving energy and further improving the environmental friendliness of the filter cleaning device 100.

[0182] Please refer to the reference. Figure 6 , Figure 9 as well as Figure 10 In one embodiment of this application, the dehydration module 51 further includes a flow guide 515, which is connected to the air blowing hole 512 and is flared in the air passage direction of the air blowing hole 512.

[0183] The air deflector 515 can be a conical cylindrical structure with openings at both ends, and the end with the smaller opening can be connected to the air blowing pipe 511.

[0184] In this embodiment, by providing a flow guide shroud 515 at the air blowing hole 512, the airflow blown out of the air blowing hole 512 can be guided to increase the air blowing coverage of the filter 300, thereby improving the drying efficiency and effect of the dehydration module 51 on the filter 300.

[0185] Please refer to the reference. Figure 6 , Figure 9 as well as Figure 10 In one embodiment of this application, at least a portion of the air blowing pipe 511 extends along the conveying direction intersecting the conveying surface 11, and at least two air blowing holes 512 are provided along the direction intersecting the conveying surface 11; the number of guide hoods 515 is at least two, and each guide hood 515 is connected to one air blowing hole 512.

[0186] At least a portion of the air blowing pipe 511 extends along the conveying direction intersecting the conveying surface 11, or at least a portion of the air blowing pipe 511 extends in the vertical direction, and at least two air blowing holes 512 are provided in the vertical direction so that at least two guide shrouds 515 can be installed accordingly.

[0187] In this embodiment, at least two flow guides 515 arranged along the direction are installed on the air blowing pipe 511, which can further increase the air blowing coverage of the filter 300 located on the conveyor line 10, thereby further improving the drying efficiency and effect of the dehydration module 51 on the filter 300. Multiple branch pipes can be protruding from the side circumference of the air blowing pipe 511 extending in the vertical direction, with the openings at the ends of the branch pipes forming air blowing holes 512, thus facilitating the installation and connection of the flow guides 515. In some embodiments, when no flow guides 515 are provided, the air blowing holes 512 can be formed directly by opening holes in the side circumference of the air blowing pipe 511.

[0188] Please refer to Figure 6 In one embodiment of this application, the second position sensor 514 is located upstream of the conveyor line 10 relative to the air inlet 512.

[0189] In this embodiment, the second position sensor 514 is positioned upstream of the air outlet 512, so that the filter 300 can pass through the second position sensor 514 first during the conveying process. This improves the timeliness of opening the second control valve 513 when the filter 300 passes through the air outlet 512, so as to start the drying operation of the filter 300 in a timely manner.

[0190] Please refer to Figure 6 In one embodiment of this application, the second positioning sensor 514 is disposed in the fixed abutment member 23 of the limiting mechanism 20.

[0191] When the fixed abutment 23 is arranged on both sides of the conveyor line 10 as described above, the second position sensor 514 can be installed on the upper surface of the fixed abutment 23. The installation of the second position sensor 514 on the fixed abutment 23 can be by screw connection, snap connection or adhesive connection, etc. This application does not limit the installation method of the second position sensor 514.

[0192] In this embodiment, the second positioning sensor 514 is installed in the fixed abutment member 23 in the limiting mechanism 20, so that the fixed abutment member 23 can be used to provide a mounting position, which is beneficial to the structural design of the filter cleaning device 100. At the same time, it also allows the second positioning sensor 514 to be closer to the filter 300 located on the conveyor line 10, which makes it easier for the second positioning sensor 514 to more accurately detect the delivery position of the filter 300.

[0193] In one embodiment of this application, the second position sensor 514 is a proximity sensor.

[0194] In this embodiment, the second positioning sensor 514 is configured as a proximity sensor so that it will not come into contact with the filter 300 when detecting the positioning of the filter 300, thereby preventing any impact on the delivery of the filter 300 or causing wear.

[0195] Please refer to Figure 6 In one embodiment of this application, the number of dehydration modules 51 is at least two, and the at least two dehydration modules 51 are arranged along the conveying direction of the conveying line 10.

[0196] When the conveyor line 10 is set to extend in the left-right direction as described above, it can also be said that at least two dehydration modules 51 are arranged in the left-right direction.

[0197] In this embodiment, the number of dehydration modules 51 is set to at least two, which facilitates continuous air blowing on the filter 300 during the conveying process, thereby improving the drying effect of the filter 300. At the same time, after the filter 300 is conveyed through each dehydration module 51, the second control valve 513 in the dehydration module 51 can be closed, thereby saving energy consumption.

[0198] Additionally, it should be noted that each dehydration module 51 may include only one air blowing pipe 511, or it may include two or more dehydration pipes arranged side by side along the conveyor line 10, and the two or more dehydration pipes may merge and share a second control valve 513.

[0199] Please refer to the reference. Figure 6 and Figure 9 In one embodiment of this application, the dehydration mechanism 50 further includes an airflow drive 52 and a connecting pipe 53; the connecting pipe 53 connects the airflow drive 52 and each of the blowing pipes 511 in at least two dehydration modules 51, and the airflow drive 52 is configured to drive airflow through the connecting pipe 53 to the blowing pipes 511.

[0200] The airflow drive component 52 can provide driving force to drive the airflow to the blowing pipe 511. The airflow drive component 52 can be an air pump or a fan; this application does not limit the type of the airflow drive component 52. The connecting pipe 53 can connect to the blowing pipes 511 in each dehydration module 51. Therefore, a portion of the connecting pipe 53 can extend along the arrangement direction of at least two dehydration modules 51. Simultaneously, the connecting pipe 53 can also communicate with the airflow drive component 52, thereby achieving indirect communication between the airflow drive component 52 and the blowing pipes 511 in each dehydration module 51.

[0201] In this embodiment, the connecting pipe 53 allows each dehydration module 51 to share a single airflow drive 52, reducing the number of airflow drive 52s required and thus simplifying the structure of the filter cleaning device 100. The airflow drive 52 also facilitates the effective formation of the required flow path for the airflow.

[0202] Please refer to Figure 4 In one embodiment of this application, there are two dehydration mechanisms 50, which are located on opposite sides of the conveyor line 10 where they intersect in the conveying direction.

[0203] When the conveyor line 10 is extended in the left-right direction as described above, the two dehydration mechanisms 50 are respectively located on the front and rear sides of the conveyor line 10, and can be further away from the conveyor line 10 than the fixed abutment 23 in the limiting mechanism 20.

[0204] In this embodiment, dehydration mechanisms 50 are provided on both the front and rear sides of the conveyor line 10, so that air can be blown on both the front and rear sides of the filter 300 located on the conveyor line 10 at the same time through the two dehydration mechanisms 50, which is conducive to improving the drying efficiency and effect of the filter 300.

The shape of the mounting cavity 42 can be the same as the shape of the machine body 40, for example, both can be square. Alternatively, the shape of the mounting cavity 42 can be different from the shape of the machine body 40. The inlet 43 and outlet 44 can be used for loading the filter 300 onto the conveyor line 10 and unloading it from the conveyor line 10, respectively. Therefore, the inlet 43 and outlet 44 can be respectively located at both ends of the conveyor line 10.

[0207] In this embodiment, the mounting cavity 42 of the machine body 40 accommodates the movable contact 21, fixed contact 23, and lead screw 221 of the conveyor line 10, cleaning mechanism 30, dehydration mechanism 50, and limiting mechanism 20, thus isolating and protecting these parts of the mechanism and reducing the possibility of damage. Simultaneously, it can collect wastewater after cleaning the filter 300, preventing operators from getting wet during filter 300 cleaning. Furthermore, when the dehydration mechanism 50 is located within the mounting cavity 42, the machine body 40 can also be provided with an air inlet and an air outlet communicating with the mounting cavity 42. The air inlet allows the gas-driven component of the dehydration mechanism 50 to draw air from outside the machine body 40, while the air outlet allows gas within the mounting cavity 42 to be discharged, thereby forming a circulating airflow.

[0208] Please refer to the reference.

This application does not limit the location of the drain outlet 45. Furthermore, the number of drain outlets 45 can be one, two, or more. This application does not limit the number of drain outlets 45. The collection box 61 is used to collect and temporarily store sewage. The collection box 61 can be arranged side-by-side with the body 40 in the front-back direction, or it can be located below the body 40. This application does not limit the location of the collection box 61. Furthermore, the collection box 61 can be a box structure with an opening, or it can be a structure including a box body and an open box cover that closes to the box body. This application does not limit the structural type of the collection box 61. The shape of the collection box 61 can be square, circular, etc., and this application does not limit the shape of the collection box 61. The drain pipe 62 connects the drain outlet 45 and the collection tank 61. The drain pipe 62 can be a rigid pipe for more stable installation of the second liquid drive component 63. Alternatively, when there are at least two drain outlets 45, the number of drain pipes 62 can be one, with at least two branches at one end near the drain outlet 45 for connection to at least two drain outlets 45. Of course, the number of drain pipes 62 can also be the same as the number of drain outlets 45, connecting one drain outlet 45 to each drain pipe 62. The second liquid drive component 63 provides power to drive the sewage in the installation cavity 42 towards the collection tank 61. The second liquid drive component 63 can be a water pump or a negative pressure tank; this application does not limit the type of the second liquid drive component 63.

[0210] In this embodiment, by setting up a collection mechanism 60, the wastewater generated in the installation cavity 42 during the cleaning of the filter 300 can be discharged and collected in an organized manner, which facilitates the centralized treatment of the wastewater in the future and will not cause pollution to the surrounding environment of the filter cleaning device 100.
