DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one 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 term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Embodiment 1:

[0034] Reference Figures 1 to 4 , which is the first embodiment of the present invention, and this embodiment provides a cleaning device for a sampling pipeline for environmental detection. The cleaning device for a sampling pipeline for environmental detection includes a supporting mechanism 100, a fixed rolling mechanism 200 and a cleaning mechanism 300. The fixed rolling mechanism 200 can realize the extension and retraction of the cleaning tool, and can be more effective in cleaning sampling bottles with different apertures. The cleaning mechanism 300 can save cleaning fluid and reduce operating steps, and there is no need to use a more complicated relay to realize water flow control.

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

[0036] The shell 102 is fixedly connected to the top of the liquid tank 101 by bolts. There are two long plates 103, which are respectively fixedly connected to the top of the shell 102. The long hole 106 and the positioning hole 107 are opened on the surface of one long plate 103. The surface of the shell 102 is connected to a liquid outlet pipe to facilitate the discharge of the cleaning liquid collected in the shell 102.

[0037] The first cover body 105 is fixedly connected to the surface of the vertical plate 104 by screws to shield and protect the contact switch 208. When the positioning rod 206d is pushed out of the positioning hole 107 by the setting of the long hole 106 on the push rod 207c, the movement of the push rod 207c is not hindered by the reset driving action of the support rebound 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 surface 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 surface 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 transported to the cylinder 301 through the conveying member 302, and the cleaning member 305 is driven by the driving member 303 so that it is inserted into the collecting bottle in a retracted state and then contacts the inner wall of the collecting bottle in an extended state for cleaning. After the collecting bottle is put on the cleaning member 305, the bottom of the collecting bottle moves and acts on it, so that the water outlet member 304 opens to discharge the water in the cylinder 301, thereby cleaning the rotating collecting bottle, and the closing can be delayed during the resetting process of the collecting bottle after cleaning, thereby improving the cleaning effect.

[0044] The cleaning member 305 is provided to facilitate insertion into the collection bottle without obstruction due to the small mouth of the sampling bottle and the large body of the bottle, when a longer brush is inserted into the bottle mouth. After being inserted into the collection bottle, the driving member 303 can fully contact the inner wall of the collection bottle. On the contrary, after cleaning is completed, it can be easily removed without obstruction.

[0045] Embodiment 2:

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

[0047] Specifically, the supporting resilient 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 shell 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 the two ends of the first spring 201d are respectively fixedly connected to the shell 102 and the surface of the square plate 201c.

[0048] There are two slide bars 201b and two square plates 201c, and the two square plates 201c are respectively slidably connected to the surfaces of the two slide bars 201b. There are two first springs 201d, which are respectively sleeved on the surfaces of the two slide bars 201b. After the rack 201a and the collection bottle move to the cleaning position, the first spring 201d is in a compressed state, providing power for the reset when the cleaning is completed, and no manual reset is required.

[0049] The fixed rolling member 202 includes a supporting roller 202a, a square rod 202b, a slider 202c, a motor 202d, a pressure roller 202e, a second spring 202f, a limiting ring 202g and a rubber sleeve 202h. The supporting 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 surface of the slider 202c, the limiting ring 202g is sleeved on the surface of the supporting roller 202a, and the rubber sleeve 202h is sleeved on the surfaces of the supporting roller 202a and the pressure roller 202e.

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

[0051] Initially, the second spring 202f is in a normal state, and the slider 202c, the motor 202d and the pressure roller 202e are at a high position, and the collection bottle is not pressed down to fix. After being pressed down and fixed, the second spring 202f is in a stretched state. Under the action of the limit member 203 limiting the slider 202c, the second spring 202f will not retract to allow the block 207j and the pressure roller 202e to move up and reset. Only when the limit 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 and reset under the action of the second spring 202f.

[0052] There are two limiting rings 202g, which are respectively fixedly connected to the surfaces of the two supporting rollers 202a, and come into contact with the collecting bottle when it is placed, so as to limit the collecting bottle. There are three rubber sleeves 202h, which are respectively fixedly connected to a pressure roller 202e and the surfaces of the two supporting rollers 202a. The rubber sleeves 202h are used to protect the collecting bottle when it is placed and fixed, and at the same time, when the motor 202d drives the pressure roller 202e to rotate, the collecting bottle can be rotated more stably.

[0053] The limiting member 203 includes a round rod 203a, a buckle 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 buckle 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, the two ends of the torsion spring 203c are respectively fixedly connected to the round rod 203a and the surface of the buckle plate 203b, the round block 203d is fixedly connected to the surface of the buckle plate 203b, the surface of the buckle 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 abutment plate 204.

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

[0055] There are several balls 203e, which are circumferentially distributed on the surface of the round block 203d. The balls 203e reduce the resistance between the round block 203d and the abutment plate 204, so that the round block 203d can move more smoothly.

[0056] The positioning member 206 includes a connecting plate 206a, an L-shaped rod 206b, a limit block 206c, a positioning rod 206d, a third spring 206e and a handle 206f.

[0057] The L-shaped rod 206b passes through the connecting plate 206a and is slidably connected thereto, and the limit block 206c is fixedly connected to the surface of the L-shaped rod 206b. After the limit block 206c contacts the connecting plate 206a after moving up with the L-shaped rod 206b, the connecting plate 206a and the slider 202c can be driven to move. The positioning rod 206d passes 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 can be driven downward, and the pressure roller 202e can be moved 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 the third spring 206e is compressed.

[0058] Pull the handle 206f to move horizontally, and the slider 202c is limited by the action of the stop plate 204 on the limit member 203. When the positioning rod 206d moves horizontally with the L-shaped rod 206b and faces the positioning hole 107, the positioning rod 206d is inserted into the positioning hole 107 under the action of the third spring 206e, and the frame 201a and the structure thereon are restricted so that it will not return to its original position. At this time, the collection bottle moves to the cleaning position for cleaning.

On the surface of the frame 201a, the fixed rod 207e is fixedly connected to the surface of the second cover body 205, the ratchet 207f is sleeved on the surface of the fixed rod 207e, the second gear 207g is sleeved on the outer ring of the ratchet 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 tooth plate 207b, the two ends of the fourth spring 207i are respectively fixedly connected to the tooth plate 207b and the surface of the connecting block 207a, the block 207j is fixedly connected to the upper end of the tooth plate 207b, the first gear 207d is meshed with the second gear 207g, and the third gear 207h is meshed with the tooth plate 207b.

[0060] There are two connecting blocks 207a, and the tooth plate 207b passes through the two connecting blocks 207a and is slidably connected thereto. The upward movement of the tooth plate 207b can drive the push rod 207c to move upward, and push 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 structure on the frame 201a return to their original positions accordingly.

[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.

The ratchet 207f allows the second gear 207g to rotate only in one direction and not in reverse.

[0062] The fourth spring 207i is used to compress the tooth plate 207b after it moves upward, providing power for the tooth plate 207b and the push rod 207c to reset, and the block 207j is used to limit the tooth plate 207b to prevent the tooth plate 207b from moving excessively and disengaging from the connecting block 207a.

[0063] Embodiment 3:

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

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

[0066] The cleaning liquid in the liquid tank 101 is transported to the cylinder 301 through the first curved pipe 302b and the second curved pipe 302c by the operation of the delivery pump 302a, and is discharged when the water outlet 304 is opened to rinse 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 the two ends of the fifth spring 305d are respectively fixedly connected to the inner wall of the cylinder 301 and the surface of the circular plate 305c.

[0068] There are two first short rods 305a, which penetrate 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 cleaning brush 305b is initially close to the cylinder 301 through the fifth spring 305d, so that it can be conveniently passed through the bottle mouth and placed in the collection bottle. Under the action of the driving member 303, the cleaning brush 305b is moved 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, power is provided for the reset of the cleaning brush 305b, the first short rod 305a and the circular plate 305c.

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

[0070] There are several air bags 304f, which are equidistantly arranged at the bottom of the arc plate 304a. There are several water outlet holes 304b. When the water outlet holes 304b on the arc plate 304a are opposite to 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 covered on the surface of the cleaning brush 305b, as the collection bottle moves, the bottom of the bottle contacts the arc plate 304a, squeezing it to move, thereby moving the T-block 304d in the T-slot 304c, and compressing the sixth spring 304e, so that the water outlet holes 304b on the arc plate 304a are opposite to the water outlet holes 304b on the cylinder 301, and the cleaning liquid in the cylinder 301 is discharged to clean the collection bottle.

[0071] The arc plate 304a and the cylinder 301 are connected by the T-slot 304c and the T-block 304d, and can move relatively to each other. The sixth spring 304e is compressed to provide power for the T-block 304d and the arc plate 304a to reset. The airbag 304f is set to adjust the buoyancy of the arc plate 304a according to the number of airbags 304f in the bottle, and then adjust the resistance between the rubber pad 304g and the cylinder 301. As the movement progresses, the number of airbags 304f subjected to buoyancy gradually decreases. When the rebound force cannot be overcome, the water outlet 304b is reset and closed to achieve delayed closure of water outlet. The friction between the rotation of the collection bottle and the arc 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 stop 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, and the U-shaped rod 303c is slidably connected to the surface of the cylinder 301. Connected to the surface 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 resistance block 303e is fixedly connected to the other end of the U-shaped rod 303c, the fixed block 303f, the seventh spring 303g and the support 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 fixed block 303f and the surface of the vertical plate 104, and the support block 303h is fixedly connected to the top of the resistance plate 204.

[0073] The second short rod 303a passes through the cylinder 301 and is slidably connected thereto, a sealing sleeve is arranged 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 arranged between the U-shaped rod 303c and the cylinder 301, and there are two seventh springs 303g and two fixed blocks 303f. When the fixed block 303f moves with the U-shaped rod 303c to drive the seventh spring 303g to stretch, the seventh spring 303g provides power for resetting the U-shaped rod 303c, the extrusion block 303d and the fixed block 303f.

[0074] When the frame 201a moves and contacts the stop block 303e, the stop block 303e drives the U-shaped rod 303c to move along with the movement of the frame 201a, thereby moving the extrusion block 303d to squeeze the protrusion 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, and the cleaning operation is performed under the action of the rotation of the collection bottle. The U-shaped rod 303c is slidably connected to the support block 303h to support the U-shaped rod 303c, reduce the force and prevent deformation.

[0075] When in use, the present invention has two working states. The first working state is to fix and limit the collection bottle, and at the same time, the cleaning brush 305b is conveniently inserted into the collection bottle, the frame 201a and the mechanism thereon are moved to the initial position at the end of the device, the collection bottle is placed on the surface of the two supporting rollers 202a, and the bottom of the bottle is in contact with the limiting ring 202g, and then the handle 206f is held to 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, and then the handle 206f is pulled 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 are moved to the cleaning position.

[0076] As the round block 203d on the movable limiting member 203 contacts and is squeezed by the abutment plate 204, the two round blocks 203d separate and the buckle plate 203b rotates, the upper end of the buckle plate 203b is buckled on the top of the slider 202c, limiting the slider 202c and the pressure roller 202e, and the torsion spring 203c is deformed to generate torque. When the frame 201a just contacts the abutment block 303e, the collection bottle moves completely onto the surface of the cleaning brush 305b and 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 cleaning tool can be extended and retracted by the fixed rolling mechanism 200. Compared with the prior art, it has a wider range of application and can be more effective in cleaning sampling bottles with different apertures. The cleaning mechanism 300 can save cleaning fluid and reduce operating steps. Compared with the prior art, the flushing fluid will not flow continuously during the replacement process of the collection bottle after cleaning, and there is no need to use a more complicated 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 rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
