[0002] An air quality sampling system is a device for sampling and detecting air quality. By sampling and analyzing the air, it can monitor air quality. During the detection process, a filter element is used to filter out larger particulate impurities in the air.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Example 1

[0031] Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a cleaning device for a sampling system filter element 105, which can increase the pressure of the cleaning water flowing to the outside through the filter element 105 during the rinsing and cleaning process, so that impurities on its surface can be quickly removed from the filter surface of the filter element 105. It includes an installation component 100, including a support plate 101, a support frame 102 disposed on one side of the support plate 101, a fixed pipe 103 disposed on one side of the support frame 102, a conveying pipe 104 disposed on one side of the fixed pipe 103, an upper sleeve 106 disposed on one side of the fixed pipe 103, and a filter element 105 disposed on one side of the upper sleeve 106; and a pushing component 200, including a pushing assembly 201 disposed in the fixed pipe 103, a traction assembly 202 disposed on the side wall of the fixed pipe 103, a connecting assembly 203 disposed in the fixed pipe 103, and a pressing assembly 204 disposed on one side of the connecting assembly 203.

[0032] Specifically, filter element 105, such as Figure 1 As shown, its upper end abuts against the upper sleeve 106, the fixed pipe 103 is fixedly connected to the support frame 102, and the upper sleeve 106 and the fixed pipe 103 are rotatably connected, which can drive the filter element 105 to rotate relative to the fixed pipe 103. The conveying pipe 104 is fixedly connected to the side wall of the fixed pipe 103, and its outlet is connected to the inside of the fixed pipe 103. The rotatable connection between the upper sleeve 106 and the fixed pipe 103, and the abutting contact part between the upper sleeve 106 and the filter element 105 are all sealed by sealing rings to prevent cleaning water from leaking through these parts.

[0033] Furthermore, the propulsion assembly 201 includes an end tube 201d disposed at one end of the fixed tube 103, a propulsion rod 201a slidably connected through the end tube 201d, a guide groove 201b formed on the side wall of the propulsion rod 201a, a guide block 201e fixedly connected to the inner wall of the end tube 201d, a handle 201c rotatably connected to one end of the propulsion rod 201a, and a blocking plate 201f rotatably connected to the end of the propulsion rod 201a located inside the fixed tube 103. The traction assembly 202 includes a sliding tube 202a slidably connected to the side wall of the fixed tube 103, a communicating groove 202c formed on the side wall of the sliding tube 202a, a toothed plate 202b fixedly connected to the side wall of the fixed tube 103, the toothed plate 202b located within the communicating groove 202c, a rotating frame 202d fixedly connected to the side wall of the sliding tube 202a, and a connecting shaft rotatably connected through one side of the rotating frame 202d. The connecting shaft is located inside the rotating frame 202d and has a gear 202f connected to its side wall. The gear 202f meshes with the toothed plate 202b. A closing plate 202g is fixedly connected to the side wall of the connecting shaft. The connecting assembly 203 includes a movable tube 203a that is slidably connected inside the fixed tube 103. A through groove 203c is provided on the side wall of the fixed tube 103. A connecting block 203b is fixedly connected to the side wall of the movable tube 203a. The connecting block 203b passes through the through groove 203c and is fixedly connected to the sliding tube 202a. The pressing assembly 204 includes a fixed frame 204a that is fixedly connected to the side wall of the push rod 201a. A rotating base 204b is fixedly connected to the side wall of the fixed frame 204a. A swing shaft 204d is rotatably connected through the rotating base 204b. A pressure plate 204c is fixedly connected to the side wall of the swing shaft 204d. A torsion spring 204e is provided on the side wall of the swing shaft 204d.

[0034] The rotatable connection between the handle 201c and the push rod 201a allows for convenient operation during the downward movement of the push rod 201a as the handle 201c presses down, guiding rotation through the contact between the guide groove 201b and the guide block 201e. The guide block 201e is fixedly connected to the inner wall of the end tube 201d and slides relative to the guide groove 201b. Since the guide groove 201b has a helical inclined structure, the relative sliding between the guide groove 201b and the guide block 201e during the downward movement of the push rod 201a causes it to rotate simultaneously. The fixing bracket 204a is fixedly connected to the side wall of the push rod 201a, and the pressure plate 204 on it... c contacts the end of the sliding tube 202a, which can drive the sliding tube 202a to move downward during the downward movement of the push rod 201a, and can also drive the sliding tube 202a to move upward during the upward movement of the push rod 201a. The state switch is the maximum moving distance of the sliding tube 202a. At this time, after the pressure plate 204c rotates, it slides relative to the sliding tube 202a and enters the sliding tube 202a, finally changing its relative position with the sliding tube 202a. During this process, the torsion spring 204e can provide torsional force for the rotation and reset of the pressure plate 204c, which can drive the sliding tube 202a to slide up and down. The blocking plate 201f slides and fits against the inner wall of the filter element 105, and the cleaning water is in the area between the blocking plate 201f and the fixed tube 103, and moves through the area where the filter element 105 is above the blocking plate 201f.

[0035] When using, first place the filter element 105 in a container such as... Figure 1Below the upper sleeve 106, the filter element 105 is inserted into the upper sleeve 106. Then, the push rod 201a is pressed down by the handle 201c. At this time, the guide groove 201b on the push rod 201a slides into contact with the guide block 201e. Under the relative sliding drive of the inclined guide groove 201b and the guide block 201e, the push rod 201a moves down and rotates relative to the fixed pipe 103. At this time, the cleaning water is transported to the fixed pipe 103 through the delivery pipe 104. At this time, the cleaning water is stored in the filter element 105 between the block plate 201f and the fixed pipe 103 under the action of the block plate 201f. As the cleaning water is continuously transported, the water pressure of the cleaning water in the filter element 105 continuously increases, so that it can be discharged through the filter element 105. To provide a pressurizing effect, it facilitates the rinsing of external impurities and residual dust from the filter element 105. As the push rod 201a moves downward, the pressure plate 204c inside the rotating base 204b on the fixed frame 204a contacts the movable tube 203a. Initially, under the elastic support of the torsion spring 204e, the pressure plate 204c can drive the movable tube 203a to slide downward within the fixed tube 103. When the connecting block 203b slides to the bottom of the through groove 203c, the movable tube 203a is pressed against it. The pressure plate 204c rotates relative to the rotating base 204b under the connection of the rotating shaft 202e. At this time, the pressure plate 204c slides relative to the movable tube 203a. When the pressure plate 204c and the movable tube 203a rotate to a certain angle, the pressure plate 204c slides relative to the movable tube 203a. Figure 3 It can be seen that the pressure plate 204c can slide on the inner wall of the movable tube 203a and separate from the fixed tube 103 and the movable tube 203a, thereby driving the movable tube 203a to slide down in the fixed tube 103, and then follow the blocking plate 201f into the filter element 105 to rotate and move down, which can assist in the cleaning of the inside of the filter element 105.

[0036] As the sliding tube 202a moves downward, it drives the connecting block 203b to slide downward within the through groove 203c. At this time, the connecting block 203b drives the sliding tube 202a to slide on the side wall of the fixed tube 103. Meanwhile, the gear 202f connected to the connecting shaft in the rotating frame 202d meshes with the toothed plate 202b located on the side wall of the fixed tube 103, causing the connecting shaft to rotate. This causes the closing plates 202g on both sides to move closer to the filter element 105 and wrap the filter element 105 between the closing plates 202g. The filter element 105 is then flushed by pressurized cleaning water and closed on both sides. The internal flushing method of plate 202g cleans the dust and impurities on the outside of filter element 105, achieving a rapid cleaning effect on filter element 105. After the flushing is completed, the push rod 201a can be moved upward by lifting the handle 201c. At this time, the pressure plate 204c pushes the movable tube 203a upward. Then, under the movement of the sliding tube 202a and the meshing action of gear 202f and toothed plate 202b, the closing plates 202g on both sides can be rotated and opened, thus completing the flushing and removal process of filter element 105.

[0037] In summary, by moving and sealing the blocking plate 201f, the pressure of the cleaning water inside the filter element 105 can be increased. By pressurizing, the cleaning quality and efficiency of the water on the outside of the filter element 105 during the reverse flow process can be improved, thus achieving the effect of quickly cleaning dust or impurities on the outside of the filter element 105.

[0038] Example 2

[0039] Reference Figures 4-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a contact component 205 for a cleaning device for a sampling system filter element 105, which solves the problem of residual dust on the outside of the filter element 105 that cannot be removed by rinsing. The contact component 205 includes a reciprocating plate 205a slidably connected to one side of a closing plate 202g. A limiting groove 205c is formed on one side of the closing plate 202g. A rubber block 205b is fixedly connected to one side of the reciprocating plate 205a. A pressure relief component 206 includes a pushing block 206a fixedly connected to one side of the reciprocating plate 205a. A drain hole 206b is formed on one side of the pushing block 206a. A guide rod 206c is slidably connected in the drain hole 206b. A drain groove 206d is formed in the guide rod 206c and communicates with the drain hole 206b. A return spring 206e is provided on one side of the pushing block 206a and is sleeved on the side wall of the guide rod 206c.

[0040] Specifically, the rubber block 205b contacts the outer sidewall of the filter screen during the closing process of the closing plate 202g. Through the deformable effect of its soft rubber, it can deform and contact the outside of the filter element 105, achieving the effect of cleaning impurities in the gaps of the filter element 105. One end of the guide rod 206c is fixedly connected to the closing plate 202g, and the push block 206a slides back and forth inside the closing plate 202g. The drain hole 206b is connected to the drain groove 206d, and the cleaning water can be discharged from the closing plate 202g through the drain groove 206d. When the push block 206a moves upward and blocks the drain groove 206d, the drain groove 206d is in a closed state, and the cleaning water cannot be discharged.

[0041] In use, after the closing plates 202g are closed, the filter element 105 is positioned between the two closing plates 202g. At this time, the push block 206a slides in contact with the side wall of the filter element 105. As the cleaning water accumulates, the push block 206a is pressed down, and the push block 206a gradually drives the reciprocating plate 205a to slide downward within the closing plates 202g. At this time, the guide rod 206c provides guidance for the downward movement of the push block 206a. Simultaneously, the push block 206a compresses the return spring 206e during its downward movement, thus storing energy. When the push block 206a moves to a position lower than the drain trough 206d, the cleaning water is discharged through the drain trough 206d. Since the inflow rate is greater than the outflow rate, the push block 206a continues to move downward, and the drainage... As the drainage volume of the trough 206d increases, when the drainage volume exceeds the inflow volume, the downward pressure of the cleaning water on the push block 206a is less than the upward thrust of the return spring 206e. At this point, the push block 206a gradually moves upward, and the drainage volume of the drainage trough 206d gradually decreases until it closes. As the cleaning water accumulates, the above process is repeated, thereby pushing the push block 206a in its up-and-down reciprocating movement. During this process, the push block 206a is fixedly connected to the reciprocating plate 205a, which enables the reciprocating plate 205a to move back and forth within the closing plate 202g. This causes multiple rubber blocks 205b on its sidewall to slide into contact with the outside of the filter element 105. Through this sliding contact, the cleaning effect and quality of external impurities of the filter element 105 can be improved.

[0042] In summary, by adjusting the drainage volume of the drainage channel 206d, the thrust of the push block 206a can be changed by altering the water pressure and the pressure of the return spring 206e, thereby enabling the push block 206a to move up and down reciprocally. This, in turn, drives the rubber block 205b on the reciprocating plate 205a to reciprocate and clean the exterior of the filter element 105, thus improving the cleaning quality and efficiency of the exterior of the filter element 105.

[0043] Example 3

[0044] Reference Figures 6-8This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an expansion assembly 301 for cleaning a filter element 105 in a sampling system. This solves the problem that residual moisture inside the filter element 105 after rinsing cannot be quickly cleaned, and further impurities cannot be removed. The expansion assembly 301 includes an expansion cavity 301b within a blocking plate 201f, with an elastic water bladder 301c fixedly connected within the expansion cavity 301b. A liquid inlet groove 301a is provided on one side of the blocking plate 201f, communicating with the elastic water bladder 301c. The snap-fit ​​assembly 302 includes a connecting groove 302a on the side wall of the blocking plate 201f, with a snap-fit ​​block 302b slidably connected through the connecting groove 302a. The snap-fit ​​block 302b is fixedly connected to the elastic water bladder 301c. One end of the filter element 105... The system includes a stop tube 302c, a rotating plate 302d rotatably connected inside the stop tube 302c, a mating tube 302e fixedly connected to one side of the rotating plate 302d, a contact groove 302f opened inside the mating tube 302e, a snap-fit ​​groove 302g opened on the inner wall of the connecting groove 302a, the snap-fit ​​groove 302g mating with the snap-fit ​​block 302b, a support assembly 303 including a mounting base 303a fixedly connected to one side of the support plate 101, a guide tube 303b fixedly connected to one side of the mounting base 303a, a stop tube 302c slidably connected inside the guide tube 303b, a support rod 303c fixedly connected inside the mounting base 303a, the support rod 303c extending into the stop tube 302c, a connecting spring 303d between the stop tube 302c and the mounting base 303a, the connecting spring 303d being sleeved on the side wall of the support rod 303c.

[0045] Specifically, the two inlet ports of the elastic water bladder 301c are fixedly connected to the side of the expansion chamber 301b near the liquid inlet. Cleaning water enters the elastic water bladder 301c through the liquid inlet. The elastic water bladder 301c expands in the expansion chamber 301b and abuts against the locking block 302b, which can drive the locking block 302b to slide in the connecting groove 302a. The locking block 302b slides in conjunction with the locking groove 302g. The support rod 303c extends into the abutment tube 302c and slides inside the abutment tube 302c. The two ends of the connecting spring 303d are fixedly connected to the mounting base 303a and the abutment tube 302c respectively, providing traction and reset propulsion for the up and down movement of the abutment tube 302c.

[0046] During use, when the filter element 105 is installed and fitted with the upper sleeve 106, its lower part contacts the abutment tube 302c and abuts against the rotating plate 302d. The rotating plate 302d is rotatably connected inside the abutment tube 302c, and its rotation can drive the rotation of the filter element 105. As the push rod 201a moves downward, it drives the blocking plate 201f to move inside the filter element 105. During this process, cleaning water enters the elastic water bladder 301c through the inlet groove 301a. Due to the high water pressure, the expansion of the elastic water bladder 301c can push the locking block 302b to slide in the connecting groove 302a and slide into contact with the inside of the filter element 105, assisting in cleaning the inside of the filter element 105. When the blocking plate 201f moves to the rotating plate 302d, the locking block 302b... The contact groove 302g in the contact groove 302f slides into contact. Due to the downward rotation of the push rod 201a, the mating tube 302e and the rotating plate 302d are driven to rotate in the abutment tube 302c. This can drive the rotation of the filter element 105. When the blocking plate 201f moves to the bottom of the contact groove 302f, the filter element 105 can be rotated by holding the push rod 201a and rotating it. The centrifugal force generated during its rotation can further achieve the effect of removing dust from the outside of the filter element 105. At the same time, it can also achieve the rapid removal of moisture from the outside of the filter element 105 after rinsing stops. During this process, the rubber block 205b can make lateral sliding contact with the outside of the filter element 105, further improving its cleaning effect on the outside of the filter element 105.

[0047] In summary, the engagement of the snap-fit ​​block 302b and the snap-fit ​​groove 302g, along with the pushing and rotating traction of the push rod 201a, can drive the filter element 105 to rotate. The centrifugal force generated by its rotation can assist in cleaning impurities and residual moisture, further promoting the removal of dust from the outside of the filter element 105 and improving the cleaning efficiency and quality of external impurities.
