Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, and more specifically to a glass straw cleaning device. Background Art

[0002] In experiments in the fields of chemistry, biology and medicine, glass pipettes are common reusable experimental equipment. To avoid cross contamination, glass pipettes need to be cleaned and disinfected before reuse.

[0003] In order to reuse glass straws, used glass straws need to be placed, temporarily stored, the cotton ball embedded in the tail removed, cleaned, dried, and other steps. Glass straws are prone to bumps and breakage during repeated turnover, which not only easily injures operators and poses a safety hazard, but also increases the economic cost of the experiment and reduces work efficiency. When manually pinching out the embedded cotton ball, there are often mistakes that cause the embedded cotton ball to fall into the glass straw, causing problems with the glass straw.

[0004] In addition, the current cleaning and disinfection methods for glass pipettes are either to clean them one by one manually, which has extremely low cleaning efficiency; or to place a large number of glass pipettes into a cleaning solution for cleaning, and the outer walls of the glass pipettes contact each other, resulting in contact dead corners on the surface of the glass pipettes. Cleaning and disinfection are not thorough, and there is a risk of cross-contamination, which affects the safe and rapid implementation of the experiment.

[0005] In summary, how to achieve safe and convenient cleaning of glass straws is a problem that needs to be urgently solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a glass straw cleaning device, which has a simple structure and is easy to operate, and can clean the glass straw safely and efficiently.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A glass straw cleaning device, comprising an ultrasonic cleaning machine, wherein a detachable straw placement cabinet is provided in the ultrasonic cleaning machine, wherein the straw placement cabinet is open at the top and provided with a plurality of water inlet holes at the bottom, wherein a plurality of support columns are provided in an array at the bottom of the straw placement cabinet, and an elastic buffer member for abutting against a suction port end of a glass straw is provided at the bottom of the support column;

[0015] Preferably, the side panel of the cleaning cabinet is provided with a foldable handle, and the foldable handle is hinged to the side panel via a rotating shaft.

[0016] Preferably, universal wheels are provided at the four corners of the bottom of the cleaning cabinet.

[0017] When in use, first disinfect the straw placement cabinet, and place the disinfected straw placement cabinet on the inner operating table of the clean bench; then insert the suction ends of the used glass straws one by one into the support column of the straw placement cabinet, so that the suction ends of the glass straws abut against the elastic buffer at the bottom of the support column. During the insertion process, the support column pushes out the embedded cotton ball at the end of the glass straw; then move the straw placement cabinet out of the clean bench, put it into an ultrasonic cleaning machine, and start the ultrasonic cleaning machine to ultrasonically clean the glass straws; finally, after cleaning, transfer the straw placement cabinet as a whole to an oven for drying and standby use, and put the straw placement cabinet into a temporary storage box for high-pressure sterilization before use.

[0018] The glass straw cleaning device provided by the utility model inserts the glass straw into the support column in a positive downward direction, and the support column can push out the embedded cotton ball at the end of the glass straw. Compared with the existing manual pinching method, the operation is convenient and the problem of the embedded cotton ball falling into the glass straw and causing it to be scrapped is not likely to occur.

[0019] An elastic buffer is provided at the bottom of the support column to prevent the suction end of the glass straw from directly contacting the bottom of the straw placement cabinet, which not only avoids the suction end from being damaged by collision, but also effectively prevents the residual liquid in the glass straw from flowing onto the clean work surface through the water inlet hole, effectively preventing cross contamination;

[0020] The horizontal distance between two adjacent support columns is greater than the outer diameter of the pipette section of the glass pipette, thereby preventing the glass pipette from being collided and damaged during insertion, transfer and ultrasonic cleaning, and reducing the safety risks of operators and the material costs of the experiment.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The core of the utility model is to provide a glass straw cleaning device, which has a simple structure and is easy to operate, and can clean the glass straw safely and efficiently.

[0027] The glass straw cleaning device provided by the utility model comprises an ultrasonic cleaning machine, wherein a detachable straw placing cabinet 2 is arranged in the ultrasonic cleaning machine, the straw placing cabinet 2 is open at the top and is provided with a plurality of water inlet holes at the bottom, a plurality of support columns 22 are arranged in an array at the bottom of the straw placing cabinet 2, and an elastic buffer member for abutting against the suction end of the glass straw is arranged at the bottom of the support column 22;

[0028] The height of the support column 22 is greater than the sum of the length of the glass straw and the length of the elastic buffer, the diameter of the support column 22 is less than or equal to the inner diameter of the suction port end, the horizontal distance between two adjacent support columns 22 is greater than the outer diameter of the straw section of the glass straw, and the outer diameter of the elastic buffer is greater than the outer diameter of the suction port end.

[0029] Among them, the straw placement cabinet 2 can accommodate a number of glass straws arranged in an array, which can be placed on a clean work surface or in an ultrasonic cleaning machine; the ultrasonic cleaning machine can simultaneously clean multiple glass straws in the straw placement cabinet 2 by ultrasonic cleaning. The specific type and model of the ultrasonic cleaning machine are determined according to the needs of actual production and refer to the existing technology, and will not be repeated here.

[0030] The bottom of the straw placement cabinet 2 is provided with a plurality of water inlet holes, so that the cleaning liquid can enter through the water inlet holes and the waste liquid can be discharged through the water inlet holes. The bottom of the straw placement cabinet 2 can be set as a plate-like structure, or can be set as follows Figure 1 The mesh structure 21 shown is used to increase the bottom flow area, facilitate the rapid entry of cleaning liquid and the rapid discharge of waste liquid;

[0031] The specific number, shape and size of the water inlet holes are determined according to actual production needs and will not be described in detail here.

[0032] In order to facilitate the transfer of the straw placement cabinet 2, at least one snap ring armrest 24 that can be folded inward can be provided on the top of the straw placement cabinet 2. The snap ring armrest 24 is hinged to the straw placement cabinet 2. The specific shape and size of the snap ring armrest 24 are determined according to the needs of actual production and with reference to the prior art.

[0033] When the straw placement cabinet 2 needs to be moved, the clamping ring handrails 24 are rotated to be vertically upward or nearly vertically upward, and the clamping ring handrails 24 on both sides are used to lift and carry the straw placement cabinet 2;

[0034] After being carried to the right place, the clamping ring armrest 24 turns inward under the influence of its own gravity, so that the clamping ring armrest 24 abuts against the inner side surface of the straw placement cabinet 2 to reduce the height of the straw placement cabinet 2 and facilitate its placement into the ultrasonic cleaning machine.

[0035] It should be noted that in order to prevent the clamping ring armrest 24 from contacting the outer wall of the glass straw when rotating, the horizontal distance from the clamping ring armrest 24 to the nearest support column 22 in a horizontal state needs to be set to be greater than the radius of the glass straw.

[0036] Please refer to Figure 1 The glass straws are inserted into the support column 22, and the support column 22 is used to support the glass straws in a vertical array and placed in the straw placement cabinet 2. Therefore, the diameter of the support column 22 needs to be less than or equal to the diameter of the suction end of the glass straw.

[0037] It should be noted that in order to prevent the glass straw from shaking significantly relative to the support column 22 during ultrasonic cleaning, the diameter of the support column 22 can be set to be slightly smaller than the diameter of the suction port end. The diameter difference between the two is usually set to 0.3 mm to limit the shaking range of the glass straw.

[0038] To prevent the glass straw from being damaged by collision when being inserted, the horizontal distance between two adjacent support columns 22 is greater than the outer diameter of the straw section of the glass straw, ensuring that there is still a certain gap between the outer wall surfaces of the glass straw inserted into the two adjacent support columns 22.

[0039] Taking into account that the glass straw is inserted into the support column 22 with the suction end facing downward, in order to prevent the glass straw from directly colliding with the bottom plate of the straw placement cabinet 2 during insertion, causing the suction end to break or shatter, an elastic buffer is provided at the bottom of the support column 22, and the outer diameter of the elastic buffer is larger than the outer diameter of the suction end.

[0040] When inserting the glass straw, the suction end of the glass straw contacts the top of the elastic buffer and exerts a certain amount of pressure on the elastic buffer. At this time, the operator can stop inserting the glass straw downward when he can feel the elastic resistance of the elastic buffer. The judgment is convenient and the operation is simple.

[0041] The elastic buffer can be specifically configured as an elastic mesh ball 23, elastic cotton, and a spring with a flexible cushion layer on the top, etc. Its specific material and structure are determined based on factors such as the hardness and size of the glass straw in actual production, and will not be elaborated here.

[0042] In order to facilitate the removal of the embedded cotton ball at the end of the glass straw, the length of the support column 22 can be set to be greater than the sum of the length of the glass straw and the length of the elastic buffer. Therefore, when the glass straw is inserted, the support column 22 can push out the embedded cotton ball. Compared with manually pinching out the embedded cotton ball, the operation is simple and the problem of the cotton ball falling into the inside of the glass straw is less likely to occur.

[0043] It should be noted that the length of the above-mentioned elastic buffer can be the length of the elastic buffer in a free state, or the length of the elastic buffer in a compressed state abutting against the glass straw.

[0044] When in use, first disinfect the straw placement cabinet 2, and place the disinfected straw placement cabinet 2 on the inner operating table of the clean bench; then insert the suction ends of the used glass straws one by one into the support column 22 of the straw placement cabinet 2, so that the suction ends of the glass straws abut against the elastic buffer at the bottom of the support column 22, and the support column 22 pushes out the embedded cotton balls at the ends of the glass straws during the insertion process; then move the straw placement cabinet 2 out of the clean bench, and put it into an ultrasonic cleaning machine, and start the ultrasonic cleaning machine to ultrasonically clean the glass straws; finally, after cleaning, transfer the straw placement cabinet 2 as a whole to an oven for drying for standby use, and put the straw placement cabinet 2 into a temporary storage box for high-pressure sterilization before use.

[0045] In this embodiment, the glass straw is inserted into the support column 22 in a positive downward direction, and the support column 22 can push out the embedded cotton ball at the end of the glass straw. Compared with the existing manual pinching method, the operation is convenient and the problem of the embedded cotton ball falling into the glass straw and causing it to be scrapped is not likely to occur.

[0046] An elastic buffer is provided at the bottom of the support column 22 to prevent the suction end of the glass straw from directly contacting the bottom of the straw placement cabinet 2, thereby preventing the suction end from being damaged by collision and effectively preventing the residual liquid in the glass straw from flowing onto the clean work surface through the water inlet hole, thereby effectively preventing cross contamination;

[0047] The horizontal distance between two adjacent support columns 22 is greater than the outer diameter of the straw section of the glass straw, thereby preventing the glass straw from being damaged by collision during insertion, transfer and ultrasonic cleaning, and reducing the safety risk of operators and the material cost of the experiment.

[0048] Preferably, the bottom of the straw placement cabinet 2 can be set as a mesh structure 21, and the support columns 22 are arranged at the intersections of the mesh structure 21, which not only has a large flow area, but also can effectively support the support columns 22 and prevent the support columns 22 from tipping over.

[0049] Therefore, the gaps in the mesh structure 21 are larger than the diameter of the glass straw, and are usually set to 2-6 cm.

[0050] On the basis of the above-mentioned embodiment, the structure of the elastic buffer is defined, and the elastic buffer comprises an elastic mesh group 23 sleeved outside the supporting column 22 .

[0051] The specific material, wire diameter, outer diameter and other dimensions of the elastic mesh ball 23 are determined according to actual production needs. Usually, the outer diameter of the elastic mesh ball 23 is set larger than the outer diameter of the suction mouth of the glass straw and smaller than the outer diameter of the straw section of the glass straw.

[0052] Of course, the elastic buffer can also be configured as a spring sleeved outside the support column 22, and the top end of the spring is provided with a flexible cushion layer for abutting against the suction end of the glass straw.

[0053] In addition, the spring may be replaced by a fixed sleeve, an elastic sleeve or other structures.

[0054] On the basis of the above-mentioned embodiment, the structure of the ultrasonic cleaning machine is defined. The ultrasonic cleaning machine comprises a cleaning machine cabinet 1 and a protective cover 3 . The protective cover 3 is detachably connected to the cleaning machine cabinet 1 .

[0055] The cleaning cabinet 1 and the protective cover 3 can be connected by fastening bolts, connecting pins and other connecting parts, or by rotational connection through a rotating shaft, hinges and the like; considering the connection stability and the convenience of disassembly and assembly, the protective cover 3 is usually connected to the cleaning cabinet 1 by a snap connection or the like.

[0056] Please refer to Figure 1 The ultrasonic cleaning machine cabinet 1 is provided with a control panel 4, and the control panel 4 can input cleaning instructions, such as cleaning time, ultrasonic frequency, etc. In order to facilitate the user to quickly obtain the working status of the ultrasonic cleaning machine, the control panel 4 can also display the remaining cleaning time;

[0057] A handle 31 is provided on the upper end surface of the protection cover 3 to facilitate moving the protection cover 3 .

[0058] To facilitate the movement of the ultrasonic cleaning machine, the side panel of the cleaning cabinet 1 can be provided with a foldable handle 11, and the foldable handle 11 is hinged to the side panel through a rotating shaft. The specific shape, size and distribution of the foldable handle 11 are determined according to actual production needs and will not be repeated here.

[0059] When the cleaning cabinet 1 does not need to be moved, the foldable handle 11 hangs down on the side of the cleaning cabinet 1 under its own weight, saving space; when it needs to be moved, the foldable handle 11 can be rotated to a suitable position with force.

[0060] Preferably, in order to further facilitate the movement of the cleaning cabinet 1, universal wheels 12 are provided at the four corners of the bottom of the cleaning cabinet 1. The specific structure and size of the universal wheels 12 are determined according to actual production needs with reference to the prior art and will not be repeated here.
