Description

Technical Field

[0001] This invention belongs to the field of test tube cleaning technology, specifically relating to a rotating disc for automatically cleaning water test tubes that have been filled with liquid. Background Technology

[0002] Test tubes, also known as culture tubes or sample tubes, are common laboratory glassware made of glass or transparent plastic tubing, with an open top and a closed bottom. Test tubes usually need to be cleaned after use for subsequent normal use.

[0003] For example, the invention patent with publication number CN117772733A discloses a test tube cleaning device and cleaning method. An outer tube is rotatably mounted on a disc along its axial direction. A first gear is coaxially fixedly mounted on the outer circumference of the outer tube. A cleaning shell is fixedly set at one end of the outer tube above the disc. Multiple second holes for drainage are opened on opposite sides of the cleaning shell. An elastic first cleaning plate and a second cleaning plate are rotatably mounted on the upper end of the disc. Sponges are respectively set on the opposite sides of the first cleaning plate and the second cleaning plate. A one-way bearing is installed on the side of the annular plate facing the disc. A third gear that meshes with the first gear is fixedly mounted on the outer circumference of the one-way bearing. When the one-way bearing rotates and the disc stops rotating, the outer tube can drive the first cleaning plate and the second cleaning plate to rotate simultaneously. When the one-way bearing stops rotating, the outer tube and the disc can rotate synchronously.

[0004] Based on the search of patent application publication numbers and considering their shortcomings, the following was found:

[0005] Existing test tubes have diverse bottom shapes, including flat bottoms, rounded bottoms, and semi-circular flat bottoms; however, existing test tube cleaning devices can only clean test tubes with a single bottom shape. This limitation prevents the test tube cleaning device from cleaning test tubes with different bottom shapes, thus restricting the types of test tubes that the device can automatically clean. Summary of the Invention

[0006] To address the issue that existing test tubes have diverse bottom shapes, including flat bottoms, rounded bottoms, and semi-circular flat bottoms, but existing test tube cleaning devices can only clean test tubes with a single bottom shape, thus limiting the types of test tubes that can be automatically cleaned, this invention provides a rotating disc for automatically cleaning water test tubes.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] An automatic cleaning water test tube rotating disk includes a hollow rotating shell, a rotating disk, a rotating motor, and a cleaning assembly. The rotating motor is coaxially disposed inside the rotating shell, and the rotating disk is rotatably disposed on the top of the rotating shell. The output end of the rotating motor is coaxially connected to the rotating disk.

[0009] The cleaning assembly includes two flexible units and a cleaning airbag. The two flexible units are respectively disposed opposite to each other at both ends of the rotating disk. Each flexible unit includes a flexible shaft, the direction of which is parallel to the central axis of the rotating disk. The cleaning airbag is slidably coaxially disposed on the rotating disk along the central axis of the rotating disk. The flexible shaft is used to fit against the side wall of the test tube. The cleaning airbag locks or releases its fit against the bottom of the test tube by its own expansion and contraction.

[0010] As a preferred embodiment of the present invention, the flexible shaft includes a plurality of hollow flexible shells, which are arranged sequentially from top to bottom along the central axis of the rotating disk. Adjacent flexible shells are hinged to each other, and the bottommost flexible shell is connected to the end face of the rotating disk. The left and right end faces of adjacent flexible shells are respectively on the same vertical plane.

[0011] As a preferred embodiment of the present invention, the flexible unit further includes an electromagnetic unit and a magnet unit. The internal spaces of several flexible shells are interconnected to form the hollow flexible shaft. The electromagnetic unit and the magnet unit are symmetrically arranged in the corresponding flexible shaft. The electromagnetic unit can lock or release its mutual repulsion relationship with the magnet unit.

[0012] As a preferred embodiment of the present invention, the electromagnetic unit includes an electromagnetic flexible tube, a plurality of electromagnets, a coil and a power source. The electromagnetic flexible tube is disposed inside the flexible shaft, and the plurality of electromagnets are arranged along the axial direction of the electromagnetic flexible tube inside the electromagnetic flexible tube, with adjacent electromagnets being fitted together. The coil is wound around the outer wall of the electromagnetic flexible tube, and the power source is disposed outside the flexible shaft. The coil is connected to the output terminal of the power source.

[0013] As a preferred embodiment of the present invention, the magnet unit includes a magnet hose and a plurality of magnet blocks. The magnet hose is disposed within another flexible shaft, and the plurality of magnet blocks are arranged along the axial direction of the magnet hose within the magnet hose, with adjacent magnet blocks being fitted together.

[0014] As a preferred embodiment of the present invention, the cleaning assembly further includes a hollow water spray housing, a water spray pump, several water pipes, and a water tank. The water spray housing is coaxially disposed on the end face of the rotating disk. Several water spray holes are provided on the side wall of the water spray housing. The several water spray holes are equally spaced along the central axis of the rotating disk. Several water pipes and several water spray holes are matched one-to-one. Each water pipe passes through the rotating disk through a seal and communicates with the corresponding water spray hole and the water tank. The water tank is disposed inside the rotating housing, and the water spray pump is disposed on the water tank. The water spray direction of the water spray holes is perpendicular to the straight line direction between the two flexible shafts.

[0015] As a preferred embodiment of the present invention, the cleaning assembly further includes a plastic cylinder and a cleaning air pump. The plastic cylinder is vertically disposed on the top of the water spray housing. The output end of the plastic cylinder is connected to the cleaning air bag. The cleaning air pump is connected to the cleaning air bag through an air pipe.

[0016] As a preferred embodiment of the present invention, the flexible unit further includes an adhesive airbag, an adhesive air pump, and an adhesive block. The adhesive airbag is disposed at the top end of the flexible shell near the top of the test tube. The adhesive block is disposed on the surface of the adhesive airbag. The adhesive air pump is connected to the adhesive airbag. The adhesive block is located at the bend of the side wall of the test tube.

[0017] As a preferred embodiment of the present invention, the cleaning assembly further includes a plurality of cleaning blocks, which are equally spaced along the horizontal direction on the surface of the cleaning airbag. The distances between the plurality of cleaning blocks and the central axis of the rotating disk are different from each other, and any one of the cleaning blocks is located at the bend at the bottom of the test tube.

[0018] As a preferred embodiment of the present invention, a camera is also included, which is communicatively connected to the cleaning air pump and the bonding air pump, respectively. The camera is used to observe the positions of the cleaning block and the bonding block in the test tube.

[0019] The beneficial effects of this invention are as follows:

[0020] This solution incorporates a flexible shaft and a cleaning airbag. A rotating motor controls the rotation of both the flexible shaft and the cleaning airbag. The flexible shaft adheres to the side wall of the test tube, cleaning the side wall. The cleaning airbag, through its expansion, adheres to the bottom of the test tube, cleaning the bottom. Because the shape of the cleaning airbag can vary according to the actual bottom shape of the test tube, this device can clean test tubes with flat, rounded, and semi-circular flat bottoms. This solves the problem that existing test tube cleaning devices can only clean test tubes with a single bottom shape, limiting their ability to automatically clean different types of test tubes.

[0030] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0031] Please see Figure 1-6 This embodiment provides an automatic cleaning rotating disk for water test tubes, including a hollow rotating shell 1, a rotating disk 2, a rotating motor 3, and a cleaning assembly. The rotating motor 3 is coaxially disposed inside the rotating shell 1, and the rotating disk 2 is rotatably disposed on the top of the rotating shell 1. The output end of the rotating motor 3 is coaxially connected to the rotating disk 2. The cleaning assembly includes two flexible units 4 and a cleaning airbag 5. The two flexible units 4 are respectively disposed opposite to each other at both ends of the rotating disk 2. Each flexible unit 4 includes a flexible shaft 401, the direction of which is parallel to the central axis of the rotating disk 2. The cleaning airbag 5 is slidably coaxially disposed on the rotating disk 2 along the central axis of the rotating disk 2. The flexible shaft 401 is used to adhere to the side wall of the test tube, and the cleaning airbag 5 locks or releases its adhesion to the bottom of the test tube through its own expansion and contraction. This solution, by setting flexible... The flexible shaft 401 and the cleaning airbag 5 are controlled by the rotating motor 3. The flexible shaft 401 adheres to the side wall of the test tube to clean the side wall. The cleaning airbag 5 expands and adheres to the bottom of the test tube to clean the bottom. Since the shape of the cleaning airbag 5 can change according to the actual bottom shape of the test tube, the device of this solution can clean test tubes with flat bottoms, rounded bottoms, and semi-circular flat bottoms. This solves the problem that existing test tube cleaning devices can only clean test tubes with a single bottom shape, which limits the types of test tubes that can be automatically cleaned.

[0032] Specifically, the flexible shaft 401 of this solution includes several hollow flexible shells. These flexible shells are arranged sequentially from top to bottom along the central axis of the rotating disk 2. Adjacent flexible shells are hinged to each other. The bottom flexible shell is connected to the end face of the rotating disk 2. The left and right end faces of two adjacent flexible shells are on the same vertical plane. Through this arrangement, the two flexible shafts 401 of this solution can be used together to fit test tubes with different inner diameters, thereby realizing the cleaning treatment of test tubes with different inner diameters.

[0033] Specifically, in order to achieve the effect of the two flexible shafts 401 respectively adhering to the inner wall of the test tube, the flexible unit 4 of this scheme also includes an electromagnetic unit 6 and a magnetic unit 7. The internal spaces of several flexible shells are interconnected to form a hollow flexible shaft 401. The electromagnetic unit 6 and the magnetic unit 7 are symmetrically arranged in the corresponding flexible shafts 401. The electromagnetic unit 6 can lock or release its mutual repulsion relationship with the magnetic unit 7. When the electromagnetic unit 6 starts to work, the electromagnetic unit 6 and the magnetic unit 7 generate a mutual repulsion relationship, causing the electromagnetic unit 6 and the magnetic unit 7 to move away from each other. Since the structure of the flexible shaft 401 is composed of various flexible shells, and due to the hinge relationship of each flexible shell, the movement trajectory of the flexible shaft 401 is determined, thereby making the two flexible shafts 401 adhere to the inner wall of the test tube, achieving the effect of the two flexible shafts 401 adhering to the inner wall of the test tube respectively.

[0034] Specifically, the electromagnetic unit 6 of this scheme includes an electromagnetic flexible tube 601, several electromagnets 602, a coil 603, and a power supply 604. The electromagnetic flexible tube 601 is disposed inside the flexible shaft 401. Several electromagnets 602 are arranged along the axial direction of the electromagnetic flexible tube 601 inside the electromagnetic flexible tube 601, with adjacent electromagnets 602 being fitted together. The coil 603 is wound around the outer wall of the electromagnetic flexible tube 601. The power supply 604 is disposed outside the flexible shaft 401, and the coil 603 is connected to the output terminal of the power supply 604. It is worth noting that the power supply 604 of this scheme is disposed on the rotating disk 2 and rotates together with the flexible shaft 401. In this design, the electromagnetic flexible tube 601 and electromagnet 602 function like wires. When the power supply 604 is turned on, current flows through the wires, generating a magnetic field around them. The direction and magnitude of this magnetic field are related to the direction and magnitude of the current. This magnetic field repels the magnet unit 7. Simultaneously, the structural relationship between the electromagnetic flexible tube 601 and electromagnet 602 allows the electromagnetic unit 6 to change with the structural changes of the flexible shaft 401, ensuring the normal operation of the device. Similarly, the magnet unit 7 includes a magnetic flexible tube 701 and several magnetic blocks 702. The magnetic flexible tube 701 is housed within another flexible shaft 401, and the magnetic blocks 702 are arranged along the axial direction of the magnetic flexible tube 701 within it, with adjacent magnetic blocks 702 fitting together. This structural relationship between the magnetic flexible tube 701 and magnetic blocks 702 allows the magnet unit 7 to change with the structural changes of the other flexible shaft 401, ensuring the normal operation of the device.

[0035] In addition, the cleaning assembly of this solution also includes a hollow water spray housing 8, a water spray pump 9, several water pipes 10, and a water tank 11. The water spray housing 8 is coaxially mounted on the end face of the rotating disk 2. Several water spray holes are provided on the side wall of the water spray housing 8. The several water spray holes are equally spaced along the central axis of the rotating disk 2. The several water pipes 10 and several water spray holes are matched one-to-one. Each water pipe 10 passes through the rotating disk 2 through a seal and is connected to the corresponding water spray hole and water tank 11. The water tank 11 is set inside the rotating housing 1, and the water spray pump 9 is set on the water tank 11. The water spray direction of the spray holes is perpendicular to the straight line between the two flexible shafts 401. In this solution, by setting up the water spray pump 9, the water spray housing 8, and the water tank 11, the water in the water tank 11 will be pumped into the water spray housing 8 through the water pipes 10 due to the pressure of the water spray pump 9. Inside, water is sprayed out from the spray housing 8 and flows onto the inner wall of the test tube. Then, as the flexible shaft 401 rotates relative to the test tube, it cleans the test tube. It should be noted that in this solution, the flexible shaft 401 and the cleaning airbag 5 are respectively attached to the surfaces that are in contact with the test tube with sponges. Due to the water absorption of the sponges, excess water inside the side wall of the test tube can be absorbed and the rest of the test tube can be cleaned. At the same time, the spray housing 8 and the flexible shaft 401 mounted on the rotating disk 2 will rotate with the rotation of the rotating disk 2. Since the spray direction of the spray holes on the spray housing 8 is perpendicular to the straight line between the two flexible shafts 401, the water flowing out of the spray holes will flow directly onto the side wall of the test tube, and the flexible shaft 401 cleans the side wall of the test tube. Furthermore, it is worth noting that, in order to ensure that the water pipes 10 do not become entangled when the rotating disk 2 rotates, this solution also includes a water storage shell, a water storage cover, and a connecting rod. The water storage shell is coaxially mounted inside the rotating shell 1, located between the water tank 11 and the spray shell 8. The water storage cover is coaxially and rotatably mounted on the top of the water storage shell, forming a water storage space between the water storage cover and the water storage shell. The water tank 11 is connected to the water storage space, and the connecting rod is vertically mounted, with both ends connected to the water storage cover and the rotating disk 2, respectively, so that the water storage cover rotates together with the rotating disk 2. Each water pipe 10 passes through the rotating disk 2 and the water storage cover through a seal, communicating with the corresponding spray hole and the water storage space. This arrangement ensures that the water pipes 10 do not become entangled when the rotating disk 2 rotates.

[0036] Furthermore, the cleaning assembly of this solution also includes a plastic cylinder 12 and a cleaning air pump 13. The plastic cylinder 12 is vertically mounted on the top of the water spray housing 8, and its output end is connected to the cleaning air bag 5. The cleaning air pump 13 is connected to the cleaning air bag 5 via an air pipe. The cleaning air pump 13 controls the cleaning air bag 5 to be in an expanded or contracted state, while the plastic cylinder 12 controls the position of the cleaning air bag 5, enabling the cleaning air bag 5 to clean the bottom of test tubes of different lengths and inner diameters. In addition, it should be noted that the plastic cylinder 12 of this solution is made of rigid plastic. The plastic cylinder 12 is designed to be unaffected by the magnetic field of the electromagnetic unit 6, ensuring the normal operation of the solution.

[0037] Furthermore, it is worth noting that the flexible unit 4 of this solution also includes an air-fitting bladder 402, an air-fitting pump 403, and an air-fitting block 404. The air-fitting bladder 402 is located at the top end of the flexible shell near the top of the test tube. The air-fitting block 404 is located on the surface of the air-fitting bladder 402. The air-fitting pump 403 is connected to the air-fitting bladder 402. The air-fitting block 404 is located at the bend of the side wall of the test tube. The function of the air-fitting pump 403 is to inflate or deflate the air-fitting bladder 402, so that the air-fitting bladder 402 is in an expanded or contracted state. Since the air-fitting block 404 is located on the surface of the air-fitting bladder 402 near the test tube, the air-fitting block 404 on the air-fitting bladder 402 will always be in contact with the test tube, regardless of whether the air-fitting bladder 402 is in an expanded or contracted state. It should be noted that the air-fitting block 404 will be attached to the bend of the side wall and bottom of the test tube to clean this area of ​​the test tube. It is worth noting that the flat-bottomed, round-bottomed, and semi-circular flat-bottomed test tubes in this solution are all composed of test tube sidewalls and test tube bottoms. The difference lies in the shape of the test tube bottoms. Therefore, this structure can clean the bend between the sidewalls and bottoms of any test tube.

[0038] Furthermore, the cleaning assembly of this solution also includes several cleaning blocks 14, which are equally spaced horizontally on the surface of the cleaning airbag 5. The distances between the cleaning blocks 14 and the central axis of the rotating disk 2 are different for each other, and any one of the cleaning blocks 14 is located at the bend at the bottom of the test tube. This arrangement is mainly for test tubes with a semi-circular flat bottom. Since the bottom of a semi-circular flat-bottomed test tube consists of a circular arc segment and a flat segment, the bottom of the semi-circular flat-bottomed test tube has a bend. The arrangement of several cleaning blocks 14 is to ensure that any one of the cleaning blocks 14 is located at the bend at the bottom of the test tube to clean the bend at the bottom of the test tube. Furthermore, in practical applications, since the bending points at the bottom of test tubes with different inner diameters and semi-circular flat bottoms are not uniform, there are cases where the cleaning block 14 is not located at the bending point at the bottom of the test tube after the cleaning airbag 5 expands. To solve this problem, this solution also includes a camera 15, which is communicatively connected to the cleaning air pump 13 and the bonding air pump 403. The camera 15 is used to observe the positions of the cleaning block 14 and the bonding block 404 in the test tube. This setting not only ensures that the bonding block 404 is located at the bending point between the side wall and the bottom of the test tube, but also, since the cleaning airbag 5 and the bonding airbag 402 will press and adhere to each other after expansion, by changing the air pressure ratio inside the cleaning airbag 5 and the bonding airbag 402, the position of the cleaning airbag 5 changes, thereby changing the position of the cleaning block 14 set on the surface of the cleaning airbag 5, ensuring that the position of any cleaning block 14 is located at the bending point at the bottom of the test tube.
