[0002] Environmental monitoring is a process of intermittently or continuously measuring the concentration of pollutants in the environment, observing and analyzing their changes and impacts on the environment. It is to accurately, timely and comprehensively reflect the current situation and development trend of environmental quality, and provide a scientific basis for environmental management, pollution source control, environmental planning, etc. And atmospheric detection is an important part of environmental detection. Through the suction of the device, the gas in the environment enters the sampling bottle, and then the gas is detected. Before the device officially works, the user needs to clean the sampling bottle to ensure the accuracy of the detection data.

Detailed implementation manners

[0030] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be made in conjunction with the accompanying drawings of the specification.

[0031] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Second, the "one embodiment" or "embodiment" referred to herein means a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0033] Embodiment 1:

[0034] Referring to Figures 1 to 4 , which is the first embodiment of the present invention. This embodiment provides a cleaning device for a sampling pipeline used in environmental detection. The cleaning device for the sampling pipeline used in environmental detection includes a support mechanism 100, a fixed rolling mechanism 200, and a cleaning mechanism 300. Through the fixed rolling mechanism 200, the cleaning tool can be telescoped, and it can be more in place when cleaning sampling bottles with different apertures. Through the cleaning mechanism 300, the cleaning liquid can be saved and the operation steps can be reduced, and there is no need to use a relatively complex relay to control the water flow.

[0035] Specifically, the support mechanism 100 includes a liquid tank 101, a housing 102, a long plate 103, a vertical plate 104, a first cover 105, a long hole 106, and a positioning hole 107. The housing 102 is fixedly connected to the top of the liquid tank 101. The long plate 103 is fixedly connected to the top of the housing 102. The vertical plate 104 is fixedly connected to the surface of the housing 102. The first cover 105 is fixedly connected to the surface of the vertical plate 104. The long hole 106 and the positioning hole 107 are opened on the surface of the long plate 103, and the long hole 106 communicates with the positioning hole 107.

[0036] The housing 102 is fixedly connected to the top of the liquid tank 101 by bolts. The number of long plates 103 is two, which are respectively fixedly connected to the top of the housing 102. The long hole 106 and the positioning hole 107 are opened on the surface of one long plate 103. A liquid outlet pipe is communicated with the surface of the housing 102, which is convenient for discharging the cleaning liquid collected in the housing 102.

[0037] The first cover 105 is fixedly connected to the surface of the vertical plate 104 by screws to shield and protect the contact switch 208. Through the setting of the long hole 106, when the ejector rod 207c ejects the positioning rod 206d out of the positioning hole 107, the movement of the ejector rod 207c is not hindered under the driving action of the reset of the support spring member 201.

[0038] Specifically, the fixed rolling mechanism 200 is installed on the surface of the shell 102, and includes a supporting rebound member 201, a fixed rolling member 202, a limiting member 203, a stop plate 204, a second cover body 205, a positioning member 206, a disengagement member 207, a contact switch 208 and a third cover body 209. The supporting rebound member 201 is installed on the surface of the shell 102, the fixed rolling member 202, the limiting member 203, the second cover body 205 and the third cover body 209 are arranged on the surface of the supporting rebound member 201, the limiting member 203 is arranged on the surface of the fixed rolling member 202, the disengagement member 207 is arranged on the surfaces of the fixed rolling member 202 and the second cover body 205, the stop plate 204 is fixedly connected to the surface of the shell 102, and the contact switch 208 is installed on the surface of the vertical plate 104.

[0039] After the collection bottle is moved to the cleaning position and the cleaning is completed, the supporting rebound part 201 provides the power for resetting, and automatically resets after being out of the restriction. The collection bottle to be cleaned is supported and fixed by the fixed rolling part 202. At the same time, after moving to the cleaning position, the collection bottle can be driven to rotate for cleaning. After the cleaning and resetting are completed, the fixing of the collection bottle can be released, which is convenient for the operator to take it.

[0040] When the collection bottle is fixed by the fixed rolling member 202 through the limiting member 203, during the process of moving to the cleaning position, under the action of the abutment plate 204, the limiting member 203 limits the structure on the fixed rolling member 202 to prevent the pressure roller 202e from moving up and separating from the surface of the collection bottle and affecting the normal rotation drive. After the cleaning is completed, the restriction on the corresponding structure is gradually lost during the resetting process, so that the pressure roller 202e is separated from the collection bottle, which facilitates the removal of the collection bottle. The frame 201a, the fixed rolling member 202 and the collection bottle are moved to the cleaning position through the positioning member 206 and fixed thereafter to prevent them from moving before the cleaning is completed and affecting the cleaning operation.

[0041] After the collection bottle is rotated a corresponding number of times for cleaning, the disengaging member 207 unlocks the positioning member 206, and the fixed rolling member 202, the positioning member 206 and the collection bottle are automatically reset under the action of the supporting rebound member 201, thereby reducing manual operations and improving efficiency. After the collection bottle moves to the cleaning position, the component on the driving member 303 touches the contact switch 208 through the contact switch 208, so that the motor 202d driving the pressure roller 202e runs, thereby rotating the collection bottle. After the cleaning is completed, the control of the contact switch 208 is lost during the resetting process, so that the motor 202d is turned off to avoid waste of electricity and rotation of the collection bottle.

[0042] Specifically, the cleaning mechanism 300 is installed on the surfaces of the vertical plate 104 and the liquid tank 101, and includes a cylinder 301, a conveying member 302, a driving member 303, a water outlet member 304, and a cleaning member 305. The cylinder 301 is fixedly connected to the surface of the vertical plate 104, the conveying member 302 is arranged on the surfaces of the liquid tank 101 and the cylinder 301, and the driving member 303, the water outlet member 304, and the cleaning member 305 are arranged on the surface of the cylinder 301.

[0043] The cleaning liquid in the liquid tank 101 is conveyed into the cylinder 301 through the conveying member 302. The driving member 303 is used to drive the cleaning member 305. After the cleaning member 305 is inserted into the collection bottle in a contracted state, it contacts the inner wall of the collection bottle in an extended state for cleaning. After the collection bottle is sleeved on the cleaning member 305, the bottom of the bottle acts on the water outlet member 304 as the collection bottle moves, causing the water outlet member 304 to open and drain the water in the cylinder 301, thereby cleaning the rotating collection bottle. And it can be delayed to close during the reset process after the collection bottle is cleaned, improving the cleaning effect.

[0044] The arrangement of the cleaning member 305 facilitates its insertion into the collection bottle. It will not be hindered when a long brush is inserted into the small mouth of the sampling bottle with a large bottle body. After being inserted into the collection bottle, under the action of the driving member 303, it can fully contact the inner wall of the collection bottle. On the contrary, it can be easily removed without being hindered after the cleaning is completed.

[0045] Embodiment 2:

[0046] Refer to Figures 2 to 10 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment.

[0047] Specifically, the support and rebound member 201 includes a frame 201a, a slide rod 201b, a square plate 201c, and a first spring 201d. The slide rod 201b is fixedly connected to the surface of the housing 102. The square plate 201c is sleeved on the surface of the slide rod 201b. The frame 201a is fixedly connected to the surface of the square plate 201c. The first spring 201d is sleeved on the surface of the slide rod 201b, and both ends of the first spring 201d are fixedly connected to the surfaces of the housing 102 and the square plate 201c respectively.

[0048] The number of the slide rod 201b and the square plate 201c is two. The two square plates 201c are respectively slidably connected to the surfaces of the two slide rods 201b. The number of the first springs 201d is two, which are respectively sleeved on the surfaces of the two slide rods 201b. After the frame 201a and the collection bottle move to the cleaning position, at this time the first spring 201d is in a compressed state, providing power for it during the reset after the cleaning is completed, and no manual operation is required for reset.

[0049] The fixed rolling member 202 includes a support roller 202a, a square rod 202b, a slider 202c, a motor 202d, a pressure roller 202e, a second spring 202f, a limit ring 202g, and a rubber sleeve 202h. The support roller 202a is rotatably connected to the surface of the frame 201a. The square rod 202b is slidably connected to the surface of the frame 201a. The slider 202c is slidably connected to the surface of the frame 201a and fixedly connected to the lower end of the square rod 202b. The motor 202d is fixedly connected to the surface of the slider 202c. The rotating shaft of the motor 202d is fixedly connected to one end of the pressure roller 202e. The second spring 202f is sleeved on the surface of the square rod 202b. The two ends of the second spring 202f are respectively fixedly connected to the surface of the frame 201a and the slider 202c. The limit ring 202g is sleeved on the surface of the support roller 202a. The rubber sleeve 202h is sleeved on the surfaces of the support roller 202a and the pressure roller 202e.

[0050] The number of the support rollers 202a is two, and they are rotatably connected to the surface of the frame 201a through bearings. The collection bottle can be stably supported by the two support rollers 202a. The square rod 202b penetrates through the frame 201a and is slidably connected thereto. The slider 202c is guided and limited by the square rod 202b.

[0051] Initially, the second spring 202f is in a normal state. At the same time, the slider 202c, the motor 202d, and the pressure roller 202e are at a high position and do not press and fix the collection bottle. After pressing and fixing, the second spring 202f is in a stretched state. Under the action of the limiting member 203 to limit the slider 202c, the second spring 202f will not retract to move the square block 207j and the pressure roller 202e upward to reset. Only when the limiting member 203 loses its effect on the slider 202c, the slider 202c, the pressure roller 202e, and the square rod 202b can be pulled back to reset under the action of the second spring 202f.

[0052] The number of the limit rings 202g is two, which are respectively fixedly connected to the surfaces of the two support rollers 202a, contact with the collection bottle when the collection bottle is placed, and limit the collection bottle. The number of the rubber sleeves 202h is three, which are respectively fixedly connected to the surface of one pressure roller 202e and the surfaces of the two support rollers 202a. The rubber sleeve 202h protects the collection bottle when it is placed and fixed, and at the same time, when the motor 202d drives the pressure roller 202e to rotate, the collection bottle can be rotated more stably.

[0053] The limiting member 203 includes a round rod 203a, a clamping plate 203b, a torsion spring 203c, a round block 203d, and a ball 203e. The round rod 203a is fixedly connected to the surface of the frame 201a. The clamping plate 203b is rotatably connected to the surface of the round rod 203a. The torsion spring 203c is sleeved on the surface of the round rod 203a, and the two ends of the torsion spring 203c are respectively fixedly connected to the surfaces of the round rod 203a and the clamping plate 203b. The round block 203d is fixedly connected to the surface of the clamping plate 203b. The surface of the clamping plate 203b is movably connected to the surface of the slider 202c. The ball 203e is rotatably connected to the surface of the round block 203d, and the surface of the ball 203e is movably connected to the surface of the abutting plate 204.

[0054] The clamping plate 203b is rotatably connected to the surface of the round rod 203a through a bearing. The torsion spring 203c provides power for the clamping plate 203b to reset after rotation. When the frame 201a moves to drive the clamping plate 203b and the round block 203d to move during cleaning, the abutting plate 204 separates the two moving round blocks 203d, thereby causing the two clamping plates 203b to rotate and buckle on the surface of the downward-moved slider 202c to limit the slider 202c and the pressure roller 202e. At the same time, the torsion spring 203c deforms to provide a force for the clamping plate 203b to reset.

[0055] The number of the balls 203e is several, and they are respectively circumferentially distributed on the surface of the round block 203d. The resistance between the round block 203d and the abutting plate 204 is reduced through the balls 203e, making the movement of the round block 203d smoother.

[0056] The positioning member 206 includes a connecting plate 206a, an L-shaped rod 206b, a limiting block 206c, a positioning rod 206d, a third spring 206e, and a handle 206f. The connecting plate 206a is fixedly connected to the surface of the slider 202c. The L-shaped rod 206b is slidably connected to the surface of the connecting plate 206a. The limiting block 206c is sleeved on the surface of the L-shaped rod 206b. The positioning rod 206d is slidably connected to the lower end of the L-shaped rod 206b. The two ends of the third spring 206e are respectively fixedly connected to the upper end of the positioning rod 206d and the inner wall of the L-shaped rod 206b. The positioning rod 206d is inserted into the positioning hole 107, and the handle 206f is fixedly connected to the upper end of the L-shaped rod 206b.

[0057] The L-shaped rod 206b penetrates through the connecting plate 206a and is slidably connected thereto. The limiting block 206c is fixedly connected to the surface of the L-shaped rod 206b. After the limiting block 206c contacts the connecting plate 206a after moving upward with the L-shaped rod 206b, it can drive the connecting plate 206a and the slider 202c to move. The positioning rod 206d penetrates through the L-shaped rod 206b and is slidably connected thereto. By holding the handle 206f and moving downward, the L-shaped rod 206b, the connecting plate 206a and the slider 202c are driven to move downward, so that the pressing roller 202e can move downward to fix the collection bottle. At the same time, as the L-shaped rod 206b moves downward, the positioning rod 206d contacts the top of the long plate 103, and at the same time, the third spring 206e is compressed.

[0058] Pull the handle 206f to move horizontally. Under the action of the abutting plate 204 on the limiting member 203, the slider 202c is limited. When the positioning rod 206d moves horizontally with the L-shaped rod 206b and is aligned with the positioning hole 107, under the action of the third spring 206e, the positioning rod 206d is inserted into the positioning hole 107 to limit the frame 201a and the structures thereon so that they will not return. At this time, the collection bottle moves to the cleaning position for cleaning operations.

[0059] The disengaging member 207 includes a connecting block 207a, a toothed plate 207b, a push rod 207c, a first gear 207d, a fixing rod 207e, a ratchet wheel 207f, a second gear 207g, a third gear 207h, a fourth spring 207i and a square block 207j. The connecting block 207a is fixedly connected to the surface of the frame 201a. The toothed plate 207b is slidably connected to the surface of the connecting block 207a. The push rod 207c is fixedly connected to the surface of the toothed plate 207b. The push rod 207c is inserted into the long hole 106. The first gear 207d is sleeved on the surface of the support roller 202a. The second cover body 205 and the third cover body 209 are fixedly connected to the surface of the frame 201a. The fixing rod 207e is fixedly connected to the surface of the second cover body 205. The ratchet wheel 207f is sleeved on the surface of the fixing rod 207e. The second gear 207g is sleeved on the outer ring of the ratchet wheel 207f. The third gear 207h is fixedly connected to the surface of the second gear 207g. The fourth spring 207i is sleeved on the surface of the toothed plate 207b. Both ends of the fourth spring 207i are fixedly connected to the surface of the toothed plate 207b and the connecting block 207a respectively. The square block 207j is fixedly connected to the upper end of the toothed plate 207b. The first gear 207d meshes with the second gear 207g, and the third gear 207h meshes with the toothed plate 207b.

[0060] There are two connecting blocks 207a. The toothed plate 207b passes through the two connecting blocks 207a and is slidably connected to them. By moving the toothed plate 207b upward, the ejector rod 207c can be driven to move upward, pushing the positioning rod 206d out of the positioning hole 107. Under the action of the rebound of the first spring 201d, the square plate 201c, the frame 201a and the structures on the frame 201a are correspondingly reset.

[0061] The first gear 207d is an incomplete gear. When the first gear 207d rotates four circles with the support roller 202a, the second gear 207g rotates half a circle. The third gear 207h is an incomplete gear. When it rotates half a circle with the second gear 207g, it can drive the toothed plate 207b to move upward, and then the ejector rod 207c moves upward, releasing the fixation of the positioning rod 206d, realizing automatic reset after rotating and cleaning a certain number of circles. The ratchet 207f makes the second gear 207g rotate only in one direction during rotation and will not rotate back.

[0062] After the toothed plate 207b moves upward, the fourth spring 207i is compressed, providing power for the reset of the toothed plate 207b and the ejector rod 207c. The square block 207j limits the toothed plate 207b to prevent the toothed plate 207b from moving excessively and detaching from the connecting block 207a.

[0063] Embodiment 3:

[0064] Refer to Figures 4 to 11 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0065] Specifically, the conveying member 302 includes a conveying pump 302a, a first elbow 302b and a second elbow 302c. The conveying pump 302a is fixedly connected to the surface of the housing 102. Both ends of the first elbow 302b are communicated with the liquid tank 101 and the conveying pump 302a respectively. Both ends of the second elbow 302c are communicated with the cylinder 301 and the conveying pump 302a respectively. The second elbow 302c is fixedly connected to the surface of the vertical plate 104.

[0066] Through the operation of the conveying pump 302a, the cleaning liquid in the liquid tank 101 is conveyed into the cylinder 301 through the first elbow 302b and the second elbow 302c, and is discharged when the water outlet member 304 is opened, flushing the inner wall of the rotating collection bottle.

[0067] The cleaning member 305 includes a first short rod 305a, a cleaning brush 305b, a circular plate 305c, and a fifth spring 305d. The first short rod 305a is slidably connected to the surface of the cylinder 301. The cleaning brush 305b is fixedly connected to the upper end of the first short rod 305a. The circular plate 305c is fixedly connected to the lower end of the first short rod 305a. The fifth spring 305d is sleeved on the surface of the first short rod 305a, and both ends of the fifth spring 305d are fixedly connected to the inner wall of the cylinder 301 and the surface of the circular plate 305c respectively.

[0068] There are two first short rods 305a, which respectively penetrate through the cylinder 301 and are slidably connected thereto. A sealing sleeve is provided between the first short rod 305a and the cylinder 301. There are two circular plates 305c, which are respectively fixedly connected to the lower ends of the two first short rods 305a. The fifth spring 305d makes the cleaning brush 305b initially close to the cylinder 301, facilitating passing through the bottle mouth and placing it inside the collection bottle. Under the action of the driving member 303, the cleaning brush 305b moves away from the cylinder 301 and contacts the inner wall of the collection bottle. At the same time, the fifth spring 305d is compressed. When the driving member 303 no longer acts on the cleaning brush 305b, it provides power for the reset of the cleaning brush 305b, the first short rod 305a, and the circular plate 305c.

[0069] The water outlet member 304 includes an arc-shaped plate 304a, a water outlet hole 304b, a T-shaped groove 304c, a T-shaped block 304d, a sixth spring 304e, an airbag 304f, a rubber pad 304g, and a roller 304h. The arc-shaped plate 304a is slidably connected to the surface of the cylinder 301. The water outlet hole 304b is opened on the surfaces of the arc-shaped plate 304a and the cylinder 301. The T-shaped groove 304c is opened on the surface of the cylinder 301. The T-shaped block 304d is slidably connected in the T-shaped groove 304c. Both ends of the sixth spring 304e are fixedly connected to the surface of the T-shaped block 304d and the inner wall of the T-shaped groove 304c respectively. The airbag 304f is fixedly connected to the surface of the arc-shaped plate 304a. The rubber pad 304g is fixedly connected to the surface of the arc-shaped plate 304a and is movably connected to the surface of the cylinder 301. The roller 304h is rotatably connected to the surface of the arc-shaped plate 304a.

[0070] The number of air bags 304f is several, and they are arranged equidistantly at the bottom of the arc-shaped plate 304a. The number of water outlet holes 304b is several. When the water outlet holes 304b on the arc-shaped plate 304a are aligned with the water outlet holes 304b on the cylinder 301, the cleaning liquid in the cylinder 301 can be discharged. When the collection bottle is completely sleeved on the surface of the cleaning brush 305b, as the collection bottle moves, its inner bottom contacts the arc-shaped plate 304a, causing extrusion and movement, thereby enabling the T-shaped block 304d to move in the T-shaped groove 304c and compressing the sixth spring 304e, making the water outlet holes 304b on the arc-shaped plate 304a align with the water outlet holes 304b on the cylinder 301, and discharging the cleaning liquid in the cylinder 301 to clean the collection bottle.

[0071] Through the T-shaped groove 304c and the T-shaped block 304d, the arc-shaped plate 304a and the cylinder 301 are connected, and they can move relative to each other. After the sixth spring 304e is compressed, it provides power for the reset of the T-shaped block 304d and the arc-shaped plate 304a. Through the arrangement of the air bags 304f, the buoyancy received by the arc-shaped plate 304a is adjusted according to the number of air bags 304f located inside the collection bottle during movement, thereby adjusting the resistance between the rubber pad 304g and the cylinder 301. As the number of buoyant air bags 304f gradually decreases during movement, when the resilience cannot be overcome, the water outlet holes 304b are reset and closed, realizing delayed closing of the water outlet. The friction between the rotating collection bottle and the arc-shaped plate 304a is reduced by the roller 304h.

[0072] The driving member 303 includes a second short rod 303a, a convex block 303b, a U-shaped rod 303c, an extrusion block 303d, a resisting block 303e, a fixing block 303f, a seventh spring 303g, and a supporting block 303h. The second short rod 303a is slidably connected to the surface of the cylinder 301. The convex block 303b is fixedly connected to the lower end of the second short rod 303a. The upper end of the second short rod 303a is fixedly connected to the bottom of the cleaning brush 305b. The U-shaped rod 303c is slidably connected to the surfaces of the cylinder 301 and the vertical plate 104. The extrusion block 303d is fixedly connected to one end of the U-shaped rod 303c. The resisting block 303e is fixedly connected to the other end of the U-shaped rod 303c. The fixing block 303f, the seventh spring 303g, and the supporting block 303h are sleeved on the surface of the U-shaped rod 303c. The two ends of the seventh spring 303g are respectively fixedly connected to the surface of the fixing block 303f and the vertical plate 104. The supporting block 303h is fixedly connected to the top of the resisting plate 204.

[0073] The second short rod 303a penetrates through the cylinder 301 and is slidably connected thereto. A sealing sleeve is provided between the second short rod 303a and the cylinder 301. The surface of the extrusion block 303d is slidably connected to the inner wall of the cylinder 301. A sealing ring is provided between the U-shaped rod 303c and the cylinder 301. The number of the seventh springs 303g and the fixed blocks 303f is two each. When the fixed block 303f drives the seventh spring 303g to stretch as it moves with the U-shaped rod 303c, the seventh spring 303g provides power for the reset of the U-shaped rod 303c, the extrusion block 303d and the fixed block 303f.

[0074] When the frame 201a moves and contacts the abutting block 303e, as the frame 201a moves, the abutting block 303e drives the U-shaped rod 303c to move, and then the extrusion block 303d moves to squeeze the convex block 303b so that it and the second short rod 303a move upward, thereby lifting the cleaning brush 305b to contact the inner wall of the collection bottle. Under the action of the rotation of the collection bottle, a cleaning operation is performed. The U-shaped rod 303c is slidably connected to the support block 303h, which supports the U-shaped rod 303c to reduce the force and prevent deformation.

[0075] During use, the present invention has two working states. The first working state is to fix and limit the collection bottle. At the same time, the cleaning brush 305b can be easily inserted into the collection bottle. Move the frame 201a and the mechanisms thereon to the initial position at the end of the device. Place the collection bottle on the surfaces of the two support rollers 202a, and the bottom of the bottle contacts the limit ring 202g. Then hold the handle 206f and move the connecting plate 206a and the slider 202c downward, so that the motor 202d and the pressure roller 202e move downward, and the rubber sleeve 202h on the pressure roller 202e is in close contact with the surface of the collection bottle. Then pull the handle 206f to move horizontally, so that the frame 201a, the square plate 201c, the positioning member 206, the limiting member 203, the fixed rolling member 202 and the collection bottle move to the cleaning position.

[0076] As the round blocks 203d on the moving limiting member 203 contact the abutting plate 204 and are squeezed, the two round blocks 203d separate and the buckle plate 203b rotates, and the upper end of the buckle plate 203b is buckled on the top of the slider 202c to limit the slider 202c and the pressure roller 202e, and the torsion spring 203c deforms to generate a torsion force. When the frame 201a just contacts the abutting block 303e, the collection bottle moves and completely sleeves on the cleaning brush 305b and the surface of the cylinder 301.

[0077] The second working state is that when the cleaning brush 305b is extended and contacts the collection bottle, the collection bottle rotates and water is automatically discharged, so that the cleaning brush 305b brushes and rinses at the same time when the collection bottle rotates, thereby improving the cleaning effect of the collection bottle. As the frame 201a moves, the stop block 303e drives the U-shaped rod 303c, the fixed block 303f and the squeezing block 303d to move, and the squeezing block 303d squeezes the protrusion 303b to make it and the second short rod 303a move upward, thereby lifting the cleaning brush 305b to contact the inner wall of the collection bottle.

[0078] At the same time, the first short rod 305a and the circular plate 305c move upward, and the fifth spring 305d is compressed. At the same time, as the collection bottle moves, the bottom of the bottle contacts the arc plate 304a, squeezing it and moving it, thereby moving the T-block 304d in the T-slot 304c, and the sixth spring 304e is compressed, so that the water outlet hole 304b on the arc plate 304a is opposite to the water outlet hole 304b on the cylinder 301, and the cleaning liquid in the cylinder 301 is discharged to clean the collection bottle.

[0079] The U-shaped rod 303c moves and contacts the contact switch 208, turning on the motor 202d. In this state, the positioning rod 206d is inserted into the positioning hole 107 for positioning, limiting the frame 201a, the square plate 201c and the corresponding structure. The rotation of the motor 202d shaft drives the pressure roller 202e to rotate, thereby rotating the collection bottle for cleaning.

[0080] The rotation of the collection bottle drives the rotation of the support roller 202a. When the first gear 207d rotates four circles with the support roller 202a, the second gear 207g rotates half a circle. When the third gear 207h rotates half a circle with the second gear 207g, it can drive the tooth plate 207b to move upward, thereby moving the top rod 207c upward, releasing the positioning rod 206d, and resetting it under the action of the corresponding rebound structure, thereby achieving automatic resetting after a certain number of rotations.

[0081] During the return process, when the round block 203d moves on the abutment plate 204, the buckle plate 203b will not release the limit on the slider 202c and the pressure roller 202e, and it can be released when the round block 203d is separated from the abutment plate 204. At this time, the pressure roller 202e moves up and resets to separate from the collection bottle, thereby facilitating the removal of the collection bottle. At the same time, when the U-shaped rod 303c is separated from the contact switch 208 during the return process, the motor 202d is turned off, and the cleaning brush 305b is retracted during the return process, so that the collection bottle is not hindered when it is removed from the cylinder 301 and the cleaning brush 305b.

[0082] In summary, the telescopic movement of the cleaning tool can be achieved through the fixed rolling mechanism 200. Compared with the prior art, it has a wider scope of application during use and can clean sampling bottles with different apertures more thoroughly. The cleaning mechanism 300 can save cleaning liquid and reduce operation steps. Compared with the prior art, during the replacement process after cleaning the collection bottle, the rinsing liquid will not keep flowing, and there is no need to use a relatively complex relay to control the flow of water.

[0083] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
