Description

Technical Field

[0001] This utility model relates to the field of bioanalysis technology, and in particular to a cleaning device for bioanalysis. Background Technology

[0002] In bioanalytical experiments, cleaning beakers and other glassware is a crucial step in ensuring the accuracy of experimental results. Traditional cleaning methods mostly rely on manual scrubbing, which suffers from low efficiency, difficulty in cleaning hard-to-reach areas, and a high risk of cross-contamination.

[0003] A search revealed Chinese patent CN218395203U, which discloses a cleaning device for bioanalysis, including a cleaning tank. This device can simultaneously clean the inner and outer walls of beakers of different sizes, solving the problem that existing bioanalysis containers are often cleaned manually, which is time-consuming, labor-intensive, and often results in slow cleaning speed.

[0004] However, the device still has the following problems. When the device is cleaning, the beaker is placed upside down on the top of the support rod, and then the inner and outer walls of the beaker are scrubbed by two sets of rotating brushes. However, in actual use, the residue at the bottom of the beaker also needs to be cleaned. The device lacks the corresponding cleaning components for the bottom of the beaker, which requires the staff to clean it manually again, making it difficult to effectively improve the cleaning efficiency of the device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cleaning device for biological analysis.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cleaning device for bioanalysis includes a housing, one end of which is hinged to an opening and closing door, and a drain outlet is provided on one side of the inner bottom of the housing. It also includes a cleaning component and a fixing component disposed inside the housing.

[0008] The cleaning assembly includes multiple fixed rods fixedly connected to the top of the inner shell. A fixed plate is fixedly connected to the bottom of each fixed rod. A motor is fixedly connected to the top of the inner shell near the fixed rods. A transmission box is fixedly connected to the output shaft of the motor. A pair of magnetic poles are fixedly connected to the bottom of the transmission box. A rotating element is positioned below the magnetic poles, with a distance of 5-10 mm between the magnetic poles and the rotating element, forming a closed magnetic circuit. A cleaning brush is fixedly connected to the outer wall of the rotating element, and a set of evenly distributed bristles is fixedly connected to the top of the cleaning brush. The motor drives the magnetic poles to rotate the rotating element, causing the cleaning brush to rotate. Combined with the flexible contact of the bristles, this effectively removes stubborn stains without damaging the inner wall of the container.

[0009] A fixed cylinder is fixedly connected to the inner bottom of the outer shell. A sliding plate is slidably connected to the inner circumferential wall of the fixed cylinder. An electric telescopic rod is fixedly connected to the inner bottom of the fixed cylinder, and the extension end of the electric telescopic rod is fixedly connected to the bottom end of the sliding plate. A fixed pipe is fixedly connected to the top of the sliding plate. A water pump is fixedly connected to one side of the top of the sliding plate, and one end of the water pump is fixedly connected to one end of the fixed pipe. A corrugated hose is fixedly connected to the other end of the water pump. A spray pipe is rotatably connected to the other end of the fixed pipe. A set of evenly distributed nozzles is fixedly connected to the outer circumferential wall of the spray pipe, and the nozzles are set at a 15° angle to the horizontal plane. A second motor is fixedly connected to the other side of the top of the sliding plate. A first bevel gear is fixedly connected to the output shaft of the second motor. A second bevel gear, meshing with the first bevel gear, is fixedly connected to the bottom end of the outer circumferential wall of the spray pipe. The electric telescopic rod adjusts the height of the spray pipe. The water pump and the corrugated hose work together to deliver water. The bevel gear drive causes the nozzles to rotate 360° to spray, covering all areas of the inner wall of the beaker.

[0010] Preferably, the inner bottom of the outer casing is inclined towards the drain outlet, and the fixing cylinder, fixing plate, and motor are all coaxially arranged with the outer casing. A beaker is placed below the fixing plate. The inclined outer casing design accelerates drainage and avoids liquid accumulation and contamination.

[0011] Preferably, the cleaning brush has a multi-section snap-fit ​​structure, and a waterproof cover is fixedly connected to the outer peripheral wall of the water spray pipe near the motor at two points. The multi-section snap-fit ​​structure facilitates the replacement or extension of the bristles, adapting to containers of different depths.

[0012] Preferably, the fixing assembly includes multiple suction cups fixedly connected to one end of the fixing plate, and the top ends of the multiple suction cups are jointly fixedly connected to a ring tube. The suction cups fix the outer wall of the beaker by negative pressure adsorption, avoiding stress concentration caused by mechanical clamping, and are especially suitable for thin-walled or irregularly shaped vessels.

[0013] Preferably, the top end of the ring tube is fixedly connected to multiple connecting rods, and the top ends of each connecting rod are fixedly connected to the inner top of the outer shell. The connecting rods rigidly connect the ring tube to the top of the outer shell, distributing the force on the suction cup and preventing the container from shaking during the cleaning process.

[0014] Preferably, an air pump is fixedly connected to the inner top of the outer shell near the annular tube, and one end of the air pump is fixedly connected to the annular tube. An air inlet valve is provided on one side of the outer peripheral wall of the annular tube. The air pump and the air inlet valve work together to adjust the suction force of the suction cup, ensuring both reliable fixation and easy and quick release of the container.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The rotating part is driven by the magnetic pole to rotate, and the rotating part drives the cleaning brush and bristles to rotate and scrub the bottom of the beaker. At the same time, the interaction between the second motor, the first bevel gear and the second bevel gear drives the water spray pipe to rotate, which facilitates the high-pressure cleaning fluid to thoroughly clean the inside of the beaker, effectively improving the cleaning efficiency of the device.

[0017] 2. By using an air pump to remove air from the ring tube and suction cup, a negative pressure is created between the suction cup and the beaker, thereby fixing the beaker and improving the cleaning stability of the device. Attached Figure Description

A water pump 14 is fixedly connected to one side of the top of the sliding plate 1201, and one end of the water pump 14 is fixedly connected to one end of the fixed pipe 13. The other end of the water pump 14 is fixedly connected to a corrugated hose 15, which connects to an external water supply system. The other end of the fixed pipe 13 is rotatably connected to a water spray nozzle. The outer peripheral wall of the water spray pipe 16 is fixedly connected to a set of evenly distributed nozzles 17, which are set at a 15° angle to the horizontal plane to increase the cleaning coverage.

An air inlet valve 27 is provided on one side of the outer peripheral wall of the ring tube 24, wherein the air inlet valve 27 serves to introduce air into the ring tube 24 and remove the beaker 22.

[0028] Working principle: In use, first, invert the beaker 22 and place it under the multiple suction cups 25 so that the beaker 22 is in contact with the suction cups 25. Then, start the air pump 26 to remove the air from the ring tube 24 and the suction cups 25, creating a negative pressure between the suction cups 25 and the beaker 22, thereby fixing the beaker 22. Then, start the electric telescopic rod 1202, which drives the sliding plate 1201 to rise along the inner circumferential wall of the fixed cylinder 12, allowing the water spray pipe 16 to enter the beaker 22. Then, start the water pump 14, and through the cooperation between the corrugated hose 15 and the water pump 14, the cleaning solution enters the fixed cylinder 12.
