Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of beaker cleaning equipment, and in particular to a beaker cleaning device. Background Technology
[0002] Beakers are commonly used containers in chemical experiments. They are cylindrical with a notch on one side of the top for pouring liquids. In chemical laboratories, beakers need to be reused and cleaned after each use. Currently, beakers are generally cleaned manually, which is labor-intensive.
[0003] Chinese invention patent CN201911193085.9 discloses a laboratory beaker cleaning device, including a base and a column. The base contains a beaker outer wall cleaning mechanism and an inner wall cleaning mechanism. The inner wall cleaning mechanism includes: a gas collecting box A; a rotating shaft; a gas collecting plate; a gas collecting box B with a one-way valve on the top; a sealing cap that is rotatably connected to the bottom of the gas collecting box B and fixedly connected to the rotating shaft; a brush column that is integrally formed with the rotating shaft and has a hollow structure; a gas chamber that is fixedly connected to the inner wall of the brush column; and hollow brush bristles that are connected to the outer wall of the brush column and communicate with the gas chamber. The beaker cleaning device also includes a water system, with the output end of the water system located at the brush column.
[0004] Although the laboratory beaker cleaning device in the aforementioned patent can replace manual cleaning of beakers and avoid a lot of manpower, the brush column can only rotate on its own axis when the shaft rotates, and cannot perform circumferential cleaning along the inner wall of the beaker. The bristles on the brush column are prone to aging and not rebounding properly, which makes it difficult for the bristles to make full contact with the inner wall of the beaker. This makes it difficult to remove stains with strong adhesion, and even forms a large gap between the bristles and the inner wall of the beaker, making it easy for stains to remain on the inner wall of the beaker, thus reducing the cleaning effect of the beaker. Utility Model Content
[0005] The purpose of this invention is to provide a beaker cleaning device that can perform circumferential cleaning and rolling friction on the inner wall of the beaker, thereby improving the cleaning effect.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] A beaker cleaning device includes a box body and a door that are closed to each other to form a closed cleaning chamber; a beaker clamp is provided inside the cleaning chamber, a lifting plate is located above the beaker clamp, and a lifting drive component that drives the lifting plate; when the lifting drive component moves up and down, it drives the lifting plate to move up and down.
[0008] The lifting plate is equipped with a revolution shaft that is driven at the top and connected to a rotary drive component. The bottom end of the revolution shaft is connected to a rotation shaft through a transmission component. The bottom end of the rotation shaft is connected to a brush head that can extend into the beaker and abut against the inner wall of the beaker when the lifting plate descends.
[0009] When the rotary drive drives the revolution shaft to rotate, it is transmitted through the transmission assembly so that the rotation shaft rotates around its own axis of rotation while simultaneously revolving around the axis of rotation of the revolution shaft relative to the lifting plate.
[0010] Based on the above technical solution, the present invention can be improved as follows:
[0011] Furthermore, a first installation chamber and a second installation chamber are formed next to the cleaning chamber inside the box. The lifting drive component is installed in the first installation chamber, and the liquid supply component is installed in the second installation chamber.
[0012] The rotating shaft has an internal cavity, and a connecting pipe is formed at the top of the rotating shaft, with a connecting port that communicates with the internal cavity. The connecting pipe is connected to the liquid supply assembly through a pipe. The bottom of the rotating shaft has a spray section that can extend into the beaker when the lifting plate descends. Multiple spray holes communicating with the internal cavity of the rotating shaft are opened on the outer peripheral wall and bottom wall of the spray section. During cleaning, the cleaning fluid is pressurized by the liquid supply assembly and delivered into the rotating shaft, and then sprayed onto the inner wall of the beaker through the spray holes.
[0013] Furthermore, the transmission assembly includes an internal gear ring, a rotating plate, and planetary gears; the internal gear ring is fixedly connected to the bottom surface of the lifting plate, the spray section of the revolution shaft is fixedly connected to the center of the rotating plate and extends out of the bottom surface of the rotating plate; the top end of the self-rotating shaft is rotatably connected to a position away from the center of the rotating plate and extends out of the top surface of the rotating plate to connect to the planetary gears;
[0014] The planetary gears and the internal gear ring mesh with each other and together with the rotating plate, they form a planetary gear transmission structure, so that the rotation of the revolution shaft drives the rotation shaft to rotate and revolve simultaneously.
[0015] Furthermore, the beaker clamp is a mechanical gripper, which has a drive unit and two clamping arms that can open and close relative to each other; the housing is provided with a flipping drive unit on the outside, and the drive end of the flipping drive unit is rotatably inserted into the cleaning chamber and connected to the drive unit of the mechanical gripper; when the flipping drive unit rotates, the rotation of the pneumatic gripper causes the clamped beaker to flip up and down.
[0016] Furthermore, the two clamping arms of the mechanical gripper are provided with V-shaped clamping grooves on the clamping side. During clamping, the two inclined groove sidewalls on the clamping grooves contact the outer peripheral wall of the beaker.
[0017] Furthermore, the clamping groove is provided with elastic pads on the two inclined groove sidewalls, and the elastic pads are used to abut against the outer peripheral wall of the beaker during clamping.
[0018] Furthermore, the elastic pad forms an inwardly curved surface on the contact surface, and the curvature of the curved surface corresponds to the curvature of the outer peripheral wall of the beaker.
[0019] Furthermore, the lifting drive component is a double electric lead screw, which includes two ball screws and a lead screw motor; the two ball screws are vertically installed in the second mounting chamber, and the top ends of the two ball screws are connected to each other through a transmission component, with the top end of one of the ball screws connected to the lead screw motor; the lead screw nuts in the two ball screws are connected to one side of the lifting plate.
[0020] Furthermore, a water collection chamber is formed on the bottom side of the cleaning chamber inside the box, and the cleaning chamber has a water-permeable hole on its bottom wall that connects the cleaning chamber and the water collection chamber; a detachable water collection trough is provided inside the water collection chamber, and a groove is formed at the top of the water collection trough.
[0021] Furthermore, a controller is provided on the door of the chamber, which is used to control the beaker clamp, the rotary drive, the liquid supply assembly, the lifting drive and the tilting drive to perform corresponding cleaning actions.
[0022] Compared with the prior art, the present invention has the following advantages:
[0023] This invention, by setting up a lifting plate and a lifting drive component, enables the brush head to reciprocate up and down to longitudinally scrub the inner wall of the beaker. Furthermore, by setting a revolution axis on the lifting plate and driving a rotation axis through a transmission component, the rotation axis can rotate both around its own axis of rotation and around the revolution axis of rotation under the drive of the rotation drive component. This allows the brush head to perform circumferential cleaning of the inner wall of the beaker and simultaneously perform rolling friction on the inner wall. The brush head can maintain full contact with the inner wall of the beaker to achieve thorough cleaning and remove even strongly adhesive stains from the inner wall of the beaker, thus improving the cleaning effect.

Detailed Implementation
[0036] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These descriptions are intended to aid in understanding the utility model but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0037] See Figures 1 to 10This embodiment relates to a beaker cleaning device, including a housing 1 and a door that can be opened and closed to each other, a beaker clamp disposed inside the housing 1 to clamp and flip a beaker 2, a brush head assembly disposed above the beaker clamp that can be raised and lowered, a spray section disposed on the brush head assembly that can spray liquid, a liquid supply assembly disposed on one side of the beaker clamp that can supply liquid to the spray section, a lifting drive that can drive the brush head assembly to be raised and lowered, and a flipping drive that is disposed outside the housing 1 that can drive the beaker clamp to be flipped; the brush head assembly has a rotatable brushing part; and a controller is provided on the door for controlling the beaker clamp, brush head assembly, liquid supply assembly, lifting drive, and flipping drive.
[0038] During cleaning, open the chamber door, place beaker 2 into chamber 1, and clamp and secure beaker 2 with the beaker clamp, ensuring the mouth of beaker 2 faces upwards. Close the chamber door, and use the lifting drive to lower the brush head assembly so that the brushing part extends into beaker 2. The spraying part draws cleaning liquid through the liquid supply assembly and sprays it onto the inner wall of beaker 2. The brushing part of the brush head assembly cleans the inner wall of beaker 2 in a rotating manner. After cleaning for a set time, use the lifting drive to raise the brush head assembly so that the brushing part moves out of beaker 2. The beaker clamp then flips beaker 2 downwards to pour out the waste liquid inside. After pouring out the waste liquid, the beaker clamp flips beaker 2 upwards to return it to its original position, and the above steps are repeated. Repeat the above steps until the preset number of times, and the cleaning is complete. Use the lifting drive to raise the brush head assembly so that the brushing part moves out of beaker 2, the beaker clamp is released, and the chamber door can be opened to remove beaker 2.
[0039] Specifically, the box 1 has a hollow rectangular structure and includes a top plate 101, a bottom plate 102, a left side plate 103, a right side plate 104, a front plate 105, and a back plate 106 that are spliced together. The top plate 101 is opposite to the bottom plate 102, the left side plate 103 is opposite to the right side plate 104, and the front plate 105 is opposite to the back plate 106. The box 1 is equipped with two partitions, namely the first partition 3 and the second partition 4. The first partition 3 is arranged vertically and close to the right side plate 104 of the box 1 to divide the internal space of the box 1 into a first chamber and a second chamber. The first chamber is larger than the second chamber; the second partition 4 is arranged horizontally and close to the bottom plate 102 of the box body 1. The second partition 4 is orthogonal to the first partition 3. The left, right and rear sides of the second partition 4 are respectively connected to the left side plate 103, right side plate 104 and back plate 106 of the box body 1, so as to divide the internal space of the first chamber into the first installation chamber 5 and the second installation chamber 6 vertically, and divide the internal space of the second chamber into the cleaning chamber 7 and the water collection chamber 8 vertically. The first installation chamber 5 is located above the second installation chamber 6, and the cleaning chamber 7 is located above the water collection chamber 8.
[0040] The first installation chamber 5 is equipped with a lifting drive, and the second installation chamber 6 is equipped with a liquid supply assembly. The cleaning chamber 7 is equipped with a beaker clamp and a brush head assembly. A gap is formed between the top of the first partition 3 and the top plate 101 of the housing 1, allowing a pipe to pass through. This gap connects the first installation chamber 5 and the cleaning chamber 7, so that the liquid supply assembly can supply liquid by connecting to the spray nozzle on the brush head assembly through a pipe. Since the waste liquid generally contains corrosive or toxic chemicals, a removable water collection tank 9 is provided in the water collection chamber 8. The top of the water collection tank 9 is opposite to the second partition 4 and forms a groove. The second partition 4 has a water-permeable hole 1001, which connects the cleaning chamber 7 and the water collection chamber 8. This allows the waste liquid generated during cleaning to flow from the cleaning chamber 7 into the water collection chamber 8 and be collected through the water collection tank 9, effectively preventing the waste liquid from being directly discharged into the sewer and causing pollution. After cleaning, the water collection tank 9 is removed and the waste liquid is poured into a designated chemical waste liquid container for centralized treatment. In this embodiment, multiple water-permeable holes 1001 are provided and arranged in an array on the second partition 4 to increase the range of waste liquid leakage, improve waste discharge efficiency, and prevent waste liquid accumulation.
[0041] The first installation chamber 5 and the cleaning chamber 7 form an upper opening on the front plate 105 of the housing 1, and the water collection chamber 8 forms a lower opening on the front plate 105 of the housing 1. Since it takes a certain amount of time for the waste liquid to leak from the cleaning chamber 7 to the water collection chamber 8 through the water permeable hole 1001, and the top surface of the second partition 4 is a flat surface, the waste liquid waiting to leak is easy to flow out along the top surface of the second partition 4 to the upper opening. Therefore, an overflow groove 10 is provided on the top surface of the second partition 4. In this embodiment, the overflow groove 10 is a rectangular groove structure. Depending on the actual situation, other shapes of groove structures can also be used instead. The water permeable hole 1001 is opened on the bottom wall of the overflow groove 10. The overflow groove 10 can form a space to accommodate the waste liquid waiting to leak, thereby preventing the waste liquid from flowing along the top surface of the second partition 4.
[0042] The enclosure has two doors: an upper door 11 and a lower door 12. The upper door 11 is a double-leaf door structure used to close the upper opening. The controller is located at the position opposite to the first installation compartment 5 on the upper door 11. The lower door 12 is a pull-out door structure used to close the lower opening. The lower door 12 is a rectangular plate with a handle on its outer surface. The inner surface of the lower door 12 is fixedly connected to the water collection tank 9 to form a drawer-type structure. When the lower door 12 is pulled open, the water collection tank 9 can be taken out along with the lower door 12, thereby improving the convenience of taking out and putting in the water collection tank 9.
[0043] The beaker clamp is a mechanical gripper. In this embodiment, the mechanical gripper is a pneumatic gripper 13 in the prior art. Depending on the actual needs, other forms of mechanical grippers can also be used instead, such as electric grippers or hydraulic grippers. The pneumatic gripper 13 has a drive unit 1301 and two clamping arms 1302 that can be opened and closed relative to each other. The opposite sides of the two clamping arms 1302 are clamping sides. Each clamping arm 1302 is provided with a V-shaped clamping groove on the clamping side. The clamping groove has two inclined groove side walls and a flat groove bottom wall connecting the two inclined groove walls. When clamping, the drive unit 1301 drives the two clamping arms 1302 to move closer to each other. The two inclined groove side walls of the clamping arms 1302 on the clamping groove are tangent to the outer peripheral wall of the beaker 2, so as to form a clamping force on the periphery of the beaker 2 to complete the clamping and fixing.
[0044] Each clamping arm 1302 has elastic pads 14 on the two inclined groove sidewalls of the clamping groove. During clamping, as the two clamping arms 1302 move closer together, the elastic pads 14 abut against the outer peripheral wall of the beaker 2 and compress and deform to generate elastic force. Under the action of its own elastic force, the elastic pads 14 can maintain abutment against the outer peripheral wall of the beaker 2, preventing the beaker 2 from loosening and slipping when flipped, and also preventing the clamping arms 1302 from rigidly contacting the beaker 2 and causing clamping marks. The elastic pads 14 form an inwardly curved surface on the abutment surface. The curvature corresponds to the curvature of the outer peripheral wall of beaker 2, thereby increasing the contact area between the elastic pad 14 and the outer peripheral wall of beaker 2, improving the clamping stability of beaker 2, making the force on the beaker more uniform, and avoiding stress concentration and breakage; the elastic pad 14 is provided with serrated anti-slip texture on the contact surface, which can increase the friction between the elastic pad 14 and the outer peripheral wall of beaker 2, further improving the clamping stability of beaker 2; in this embodiment, the elastic pad 14 is made of rubber, but other elastic materials can be used instead, depending on the actual situation.
[0045] The flipping drive is a first servo motor 15, which is fixedly mounted on the left side plate 103 of the housing 1. The output shaft of the first servo motor 15 passes through the left side plate 103 from the outside of the housing 1 and enters the cleaning chamber 7 inside the housing 1, and then connects to the drive part 1301 of the pneumatic gripper 13. The housing 1 has corresponding shaft holes on the left side plate 103. When the first servo motor 15 is started, the output shaft of the first servo motor 15 rotates, driving the pneumatic gripper 13 to rotate around the axis, thereby realizing the up-and-down flipping of the beaker 2. It should be noted that the installation height of the pneumatic gripper 13 should be greater than the flipping radius of the beaker 2 to avoid collision between the beaker 2 and the second partition 4 when flipping.
[0046] The brush head assembly includes a lifting plate 16, a brush head 17 mounted on the lifting plate 16, and a rotary drive component connected to the brush head 17. The lifting plate 16 has a rectangular plate structure, with a support end on the side opposite to the first partition 3. The support end of the lifting plate 16 is connected to the lifting drive component, which drives the lifting plate 16 to move up and down, so that the brush head 17 moves vertically up and down to clean the inner wall of the beaker 2.
[0047] The rotary drive is located on the top of the lifting plate 16, and the brush head 17 is rotatably located at the bottom of the lifting plate 16 and connected to the drive end of the rotary drive through a transmission assembly. When the rotary drive is started, the brush head 17 can rotate around its own rotation axis and simultaneously revolve around the central axis of the lifting plate 16.
[0048] The rotary drive component is a stepper motor 18 as in the prior art. The stepper motor 18 is fixedly mounted on the top surface of the lifting plate 16 via a bracket 19. The bracket 19 is provided with bearing holes, and a bearing is installed in the bearing holes. The bearing is inserted and fitted with a rotating shaft 20. The rotating shaft 20 is a hollow rotating shaft structure, and a cavity is formed inside the rotating shaft 20. The top end of the rotating shaft 20 is a connecting pipe, which is used to connect to the liquid supply component through a pipe. The top end of the rotating shaft 20 extends out of the top surface of the bracket 19 and is fixed by a snap ring after engaging with the bearing in the bearing hole. Near the top end, the rotating shaft 20 is connected to the output shaft of the stepper motor 18 via a synchronous pulley and synchronous belt. The bottom end of the rotating shaft 20 extends downward and passes through the bottom surface of the lifting plate 16 to form a spray section. The rotating shaft 20 has multiple spray holes on the outer peripheral wall and bottom wall of the spray section, which communicate with the internal cavity of the rotating shaft 20. The lifting plate 16 has clearance holes that allow the rotating shaft 20 to rotatably pass through.
[0049] The rotating shaft 20 has a connecting port at the connecting part that connects to the internal cavity. One end of the pipe is connected to the connecting port of the rotating shaft 20 through a ball joint (not shown in the figure), and the other end of the pipe is connected to the liquid supply assembly through a quick-connect head (not shown in the figure). When the stepper motor 18 is started, the output shaft of the stepper motor 18 rotates, and through the synchronous belt drive of the synchronous pulley, it drives the rotating shaft 20 to rotate around the axis relative to the lifting plate 16. After the cleaning fluid is pressurized by the liquid supply assembly, it is transported to the rotating shaft 20 through the pipe and sprayed onto the inner wall of the beaker 2 through the spray holes on the rotating shaft 20. In this embodiment, the ball joint is a conventional joint in the prior art. The use of the ball joint allows the pipe to remain stationary when the rotating shaft 20 rotates.
[0050] The transmission assembly is a planetary gear transmission structure, including an internal gear ring 21, a rotating plate 22, and planetary gears 23. The internal gear ring 21 is fixedly connected to the bottom surface of the lifting plate 16. The spray section of the revolution shaft 20 passes tightly through the rotating plate 22. The rotating plate 22 has a shaft hole at its center that can be interference-fitted with the revolution shaft 20. The rotating plate 22 has a bearing hole at its edge, and a bearing is installed in the bearing hole. The bearing is sleeved with a rotating shaft 24. The bottom end of the rotating shaft 24 extends out of the bottom surface of the rotating plate 22 and is fixed by a snap ring. The top end of the rotating shaft 24 is rotatably connected to a position away from the center of the rotating plate 22 and extends out of the top surface of the rotating plate 22 to connect with the planetary gears 23. The bottom end of the rotating shaft 24 forms a cavity for tightly closing the sleeve of the brush head 17.
[0051] When the stepper motor 18 starts, the revolution shaft 20 rotates, driving the rotating plate 22 to rotate around the central axis of the lifting plate 16, which in turn drives the brush head 17 to revolve around the central axis of the lifting plate 16, thus achieving circumferential cleaning of the inner wall of the beaker 2. At the same time, through the meshing of the planetary gear 23 and the internal gear ring 21, the rotation shaft 24 is driven to rotate accordingly, so that the brush head 17 can rotate around its own axis during revolution, achieving rolling friction on the inner wall of the beaker 2. This not only allows for a thorough cleaning of the inner wall of the beaker 2, but also removes stubborn stains from the inner wall of the beaker 2, improving the cleaning effect. At this time, the brush head 17 is the brushing part in the brush head assembly.
[0052] The brush head 17 includes a brush rod and bristles disposed on the outer circumference of the brush rod. The top end of the brush rod is tightly fitted into the cavity of the rotating shaft 24. In this embodiment, three brush heads 17 are provided. Correspondingly, the rotating plate 22 in this embodiment has a triangular plate structure. The rotating plate 22 is provided with rotating shafts 24 at its three sharp corners, and the rotating shafts 24 are fitted into the brush heads 17 one by one. Compared with a single brush head 17, three brush heads 17 can increase the cleaning frequency of the inner wall of the beaker 2 and further improve the cleaning effect. The number of brush heads 17 can be adjusted according to the actual situation.
[0053] It should be noted that a suitable distance should be maintained between the center of the rotating shaft 24 and the center of the rotating plate 22 so that the sleeved brush head 17 can extend into the beaker 2 when the lifting plate 16 descends, and the bristles can touch the inner wall of the beaker 2.
[0054] The lifting drive is a double-link electric lead screw, which includes two vertically arranged ball screws 25 and a lead screw motor. Each ball screw 25 includes a threaded rod, a lead screw nut threaded onto the threaded rod, and a support plate 27 connected to the lead screw nut. The support plate 27 is fixedly connected to the bottom surface of the lifting plate 16. The axial ends of the threaded rod are rotatably connected to the right side plate 104 of the housing 1 via support seats 28. The top ends of the two threaded rods are connected by a synchronous pulley and synchronous belt drive. In this embodiment, the lead screw motor is a second servo motor 26. The motor 26 is fixedly mounted on the right side plate 104 of the housing 1. The output shaft of the second servo motor 26 is connected to the top of one of the threaded rods through a coupling. When the second servo motor 26 is started, the threaded rod rotates, driving the screw nut up and down along the threaded rod to realize the lifting plate 16 lifting up and down. By changing the rotation direction of the output shaft of the second servo motor 26, the rotation direction of the threaded rod is changed accordingly, so that the screw nut can drive the support plate 27 to move up or down, thereby realizing the up and down reciprocating motion of the brush head 17 and improving the cleaning effect.
[0055] The first partition 3 has an elongated groove 301, which is vertically arranged. The top of the elongated groove 301 forms an opening at the top of the first partition 3. The support plate 27 has a rectangular plate structure. A guide portion 2701 is formed on one side of the support plate 27. The far end of the guide portion 2701 passes through the elongated groove 301, passes through the first partition 3, and enters the first installation chamber 5 to be welded and fixed to the lead screw nut. The guide portion 2701 can slide and engage with the elongated groove 301 to guide the support plate 27 to move vertically when the lead screw nut moves up and down, ensuring that the lifting plate 16 can move up and down smoothly and avoiding large-scale displacement of the brush head 17. During installation, the guide portion 2701 can slide and engage with the elongated groove 301 from the top opening of the elongated groove 301. The width of the guide portion 2701 is slightly less than the width of the elongated groove 301 to ensure smooth sliding of the guide portion 2701. The width of the support plate 27 is greater than the width of the guide portion 2701.
[0056] It should be noted that in this embodiment, a double electric lead screw is used as the lifting drive component, which can generate two lifting driving forces to smoothly drive the lifting plate 16 to rise and fall; depending on actual needs, other suitable lifting drive components that can smoothly drive the lifting plate 16 to rise and fall can also be used instead.
[0057] The liquid supply assembly includes a liquid storage tank 29, an input end connected to the outlet of the liquid storage tank 29, and an output end of the booster pump 31 connected to the pipe port of the rotating shaft 20 via a pipeline. The liquid storage tank 29 has an opening at the top and is covered with a lid. Cleaning liquid is added to the liquid storage tank 29 through the opening. The cleaning liquid is drawn into the booster pump 31, pressurized, and then transported from the output end of the booster pump 31 to the rotating shaft 20 along the pipeline. The cleaning liquid added to the liquid storage tank 29 can be selected according to the actual cleaning needs.
[0058] The storage tank 29 is equipped with a heater (not shown in the figure). The heater is used to heat the cleaning solution. The heated cleaning solution can promote the dissolution of dirt on the inner wall of the beaker 2 and improve the cleaning effect.
[0059] The right side panel 104 of the housing 1 is provided with an inspection port corresponding to the second installation chamber 6, so as to facilitate the disassembly and maintenance of the liquid supply component; a cover plate is provided at the inspection port to close the second installation chamber 6.
[0060] In this embodiment, the controller is a touch screen controller 30 in the prior art, which is embedded in the door of the enclosure. The touch screen controller 30 includes a housing, a control module disposed inside the housing, and a touch screen electrically connected to the control module. The front side of the housing forms a shell opening, and the touch screen is connected to the shell opening on the front side of the housing. When the touch screen controller 30 is embedded in the door of the enclosure, the operating surface of the touch screen is flush with the outer surface of the door of the enclosure, so as to make the appearance of the beaker cleaning device simple. The control module is used to control the pneumatic gripper 13, the first servo motor 15, the second servo motor 26, the stepper motor 18 and the booster pump 31 according to its built-in preset program to perform corresponding cleaning actions to realize the automated cleaning of the beaker 2.

All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of this utility model, shall fall within the scope of protection of this utility model.
