Description

Technical Field

[0001] The invention relates to the technical field of instrument cleaning, and in particular to an experimental instrument cleaning device. Background Art

[0002] In a laboratory environment, cleaning of glassware is a critical operation. The cleaning of laboratory instruments is related to the accuracy of experimental data and the reliability of experimental results. Currently, there are many laboratory glassware cleaning devices on the market, which usually use brushes, high-pressure water flow and chemical cleaning agents to clean laboratory instruments.

[0003] For example, the Chinese patent for a food chemistry experimental instrument cleaning device with the authorization announcement number CN220216128U is named. When in use, the experimenter presses the instrument to lower the tooth plate, and the tooth plate drives the lever to rotate through the half gear, and pushes the fixed plate and the card plate to slide. The inner wall of the slot above the lower card plate squeezes the arc end of the bottom of the spring card, and the spring pushes the card plate to slide outward to the top of the descending instrument tube edge to limit the instrument and complete the fixation of the instrument. At this time, the control motor is turned on to supply water to the outside, and the motor rotates the cleaning rod and the bristles through gears one and two. The bristles cooperate with the splashing water flow to clean the experimental instrument, so that the instrument cleaning operation can be completed quickly.

[0004] With regard to the above-mentioned related technologies, the outer contour of the brush hair fixedly connected to the cleaning stem is generally cylindrical. Therefore, when the bottle mouth of the experimental instrument is narrow and the bottle bottom is wide, the bristles are difficult to contact the inner wall of the instrument, thereby reducing the cleaning effect of the instrument. In addition, since there are many types of experimental instruments and different types of experimental instruments have different shapes, the bristles of one outer contour shape are difficult to adapt to the cleaning of instruments of different shapes, thereby having a negative impact on the cleaning effect of the instrument.

DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 9 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0025] This embodiment provides an experimental instrument cleaning device, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 A laboratory instrument cleaning device includes a cleaning shell 1, the inner side wall of the cleaning shell 1 is slidably connected to a support frame 2, the support frame 2 is fixedly connected to a first infusion tube 11, the side wall of the first infusion tube 11 is fixedly connected to an elastic shell 3, and the outer side wall of the elastic shell 3 is fixedly connected to a first brush 31. The side wall of the first infusion tube 11 is provided with a first infusion hole 111, and the first infusion hole 111 is located in the elastic shell 3.

[0026] Reference Figure 5 The top wall of the first infusion tube 11 is rotatably connected to a first infusion housing 4 for supporting the instrument 9. The first infusion housing 4 is arranged above the elastic housing 3. The side wall of the first infusion housing 4 is tangentially inclined to open a second infusion hole 41. The top wall of the first infusion housing 4 is opened to open a third infusion hole 42. The top wall of the first infusion housing 4 is fixedly connected to a second brush 43.

[0027] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7A fastening rod 5 is slidably arranged in the cleaning housing 1, and a first linear actuator 51 is fixedly connected in the cleaning housing 1 for driving the fastening rod 5 to move. A rotating ball 52 for pressing the instrument 9 is hinged on the bottom wall of the fastening rod 5, and the rotating ball 52 is made of rubber.

[0028] The experimenter puts the instrument 9 upside down on the first infusion housing 4, so that the second bristles 43 abut against the inner bottom wall of the instrument 9, and the elastic housing 3 enters the instrument 9. Cleaning liquid is injected into the first infusion tube 11, and the cleaning liquid enters the elastic housing 3 through the first infusion hole 111, so that the elastic housing 3 is stretched to fit the shape of the instrument 9, and the first bristles 31 abut against the inner wall of the instrument 9, and at the same time, the cleaning liquid in the first infusion tube 11 flows through the second infusion hole 41 and the third infusion hole 42 and is sprayed out. Since the second infusion hole 41 is set obliquely, the cleaning liquid sprayed from the second infusion hole 41 drives the first infusion housing 4 to rotate relative to the instrument 9 around the central axis of the first infusion tube 11 due to the reaction force, and the second bristles 43 rotate synchronously with the first infusion housing 4, and at the same time, the cleaning liquid is transported to the inner bottom wall of the instrument 9 through the third infusion hole 42, so that the second bristles 43 clean the inner bottom wall of the instrument 9.

[0029] After the second bristles 43 finish cleaning the inner bottom wall of the instrument 9, the first linear actuator 51 drives the fastening rod 5 to move downward, and the rotating ball 52 moves synchronously with the fastening rod 5 to abut against the outer bottom wall of the instrument 9. The rotating ball 52 presses the instrument 9 downward to increase the friction between the instrument 9 and the second bristles 43. At this time, the second bristles 43 are bent, and the first infusion housing 4 drives the instrument 9 to rotate around the central axis of the first infusion tube 11 through the second bristles 43. The second bristles 43 and the instrument 9 are relatively stationary, and the second bristles 43 stop cleaning the inner bottom wall of the instrument 9. The instrument 9 rotates relative to the elastic housing 3, and at the same time, the cleaning liquid output from the second infusion hole 41 flows downward to the inner side wall of the instrument 9, thereby allowing the first bristles 31 to clean the inner wall of the instrument 9.

[0030] While the cleaning liquid is cleaning the inner wall of the instrument 9, the cleaning liquid causes the elastic shell 3 to be expanded to adapt to the shape of the instrument 9, so that when cleaning instruments 9 of different shapes and specifications, the outer contour of the first bristles 31 can adapt to the shape of the instrument 9, and then the ends of the first bristles 31 can abut against the inner walls of instruments 9 of different shapes and specifications for cleaning, thereby increasing the types of shapes of instruments 9 that can be cleaned by the first brush 31 and improving the cleaning effect on instruments 9 of different shapes.

[0031] Reference Figure 2 and Figure 3A second linear actuator 6 is fixedly connected in the cleaning housing 1, a driving shaft of the second linear actuator 6 is fixedly connected to a first sliding frame 61, a first liquid inlet pipe 62 is fixedly connected to the first sliding frame 61, the first liquid inlet pipe 62 is arranged below the first liquid infusion pipe 11, and the first liquid inlet pipe 62 is detachably connected to the first liquid infusion pipe 11. The first liquid inlet pipe 62 is fixedly connected to a first sealing member 621, and the first liquid infusion pipe 11 is fixedly connected to a second sealing member 112 that can cooperate with the first sealing member 621. The first sealing member 621 and the second sealing member 112 are conical housings, and the inner side wall of the second sealing member 112 abuts against the outer side wall of the first sealing member 621 to improve the sealing effect between the first liquid inlet pipe 62 and the first liquid infusion pipe 11.

[0032] The second linear actuator 6 drives the first sliding frame 61 to move upward, and the first sliding frame 61 drives the first liquid inlet pipe 62 to move upward, and the first sealing member 621 moves synchronously with the first liquid inlet pipe 62 to abut against the second sealing member 112, so that the first liquid inlet pipe 62 is connected to the inside of the first liquid infusion pipe 11. The first sealing member 621 cooperates with the second sealing member 112, and the cleaning liquid in the first liquid infusion pipe 11 is discharged through the first liquid infusion hole 111, the second liquid infusion hole 41 and the third liquid infusion hole 42.

[0033] Reference Figure 2 , Figure 3 and Figure 6 The driving shaft of the first linear actuator 51 is fixedly connected to the second sliding frame 511, the second sliding frame 511 is fixedly connected to the fastening rod 5, the second sliding frame 511 is fixedly connected to the second liquid inlet pipe 512, a second liquid infusion pipe 513 is arranged below the second liquid inlet pipe 512, the second liquid infusion pipe 513 is L-shaped, and the second liquid infusion pipe 513 is arranged outside the side wall of the first liquid infusion pipe 11. The side wall of the second liquid infusion pipe 513 is provided with a fourth liquid infusion hole 514 for conveying the cleaning liquid in the second liquid inlet pipe 512 to the outer wall of the instrument 9.

[0034] When the experimenter places the instrument 9 on the second bristle 43, the first linear actuator 51 moves the rotating ball 52 downward to press the instrument 9 through the fastening rod 5, and the first linear actuator 51 drives the second sliding frame 511 to move synchronously with the fastening rod 5, and the second sliding frame 511 drives the second liquid inlet pipe 512 and the second liquid infusion pipe 513 to move downward, so that the second liquid infusion pipe 513 is located on both sides of the instrument 9. The second liquid inlet pipe 512 transports the cleaning liquid to the second liquid infusion pipe 513, and the cleaning liquid is sprayed to the outer wall of the instrument 9 through the fourth liquid infusion hole 514, thereby cleaning the outer wall of the instrument 9.

[0035] Reference Figure 6 and Figure 8The second infusion housing 7 is fixedly connected between the second infusion pipe 512 and the second infusion pipe 513, and the second infusion housing 7 is fixedly connected to the second sliding frame 511. A limiting plate 71 is fixedly connected inside the second infusion housing 7, and the limiting plate 71 is slidably connected to the fastening rod 5. A fixing plate 72 is fixedly connected inside the second infusion housing 7, and the fixing plate 72 is provided with a fifth infusion hole 721. A closing member 73 is arranged between the fixing plate 72 and the limiting plate 71, and the closing member 73 is fixedly connected to the fastening rod 5. An extrusion spring 74 is fixedly connected between the limiting plate 71 and the closing member 73. When the closing member 73 abuts against the fixing plate 72, the extrusion spring 74 is compressed to press the closing member 73 downward, so that the closing member 73 closes the fifth infusion hole 721. At this time, the closing member 73 limits the cleaning liquid in the second infusion pipe 512 from flowing to the second infusion pipe 513.

[0036] The first linear actuator 51 drives the second infusion housing 7 to move downward through the second sliding frame 511, and the fastening rod 5 moves downward with the second infusion housing 7 due to its own gravity, so that the rotating ball 52 abuts against the outer bottom wall of the instrument 9. Then the first linear actuator 51 continues to drive the second infusion housing 7 to move downward, and at this time the fastening rod 5 moves upward relative to the second infusion housing 7. Since the fixing plate 72 is fixedly connected to the second infusion housing 7, the fastening rod 5 drives the closing member 73 to move upward relative to the fixing plate 72, so that the closing member 73 is separated from the fixing plate 72, so that the cleaning liquid in the second liquid inlet tube 512 flows to the second liquid inlet tube 513 through the fifth liquid infusion hole 721.

[0037] The closing member 73 moves upward to shorten the distance between the closing member 73 and the limiting plate 71, so that the extrusion spring 74 is further compressed to press the limiting plate 71 downward. Since the fastening rod 5 is fixedly connected to the closing member 73, the fastening rod 5 is pressed downward by the extrusion spring 74 to press the instrument 9 by rotating the ball 52. After the instrument 9 is cleaned, the first linear drive 51 drives the second infusion housing 7 to move upward and reset through the second sliding frame 511.

[0038] Therefore, when the fastening rod 5 fastens the instrument 9 and the first brush 31 cleans the inner wall of the instrument 9, the fastening rod 5 drives the closing piece 73 to separate from the fixing plate 72, so that the cleaning liquid in the second liquid inlet pipe 512 is transported to the outer wall of the instrument 9 through the fifth infusion hole 721, the second infusion pipe 513 and the fourth infusion hole 514, thereby cleaning the inner and outer walls of the instrument 9 at the same time, thereby improving the cleaning efficiency of the instrument 9.

[0039] Reference Figure 4 and Fig. 9The outer wall of the elastic shell 3 is fixedly connected with an adjusting rod 8 for adjusting the position of the elastic shell 3 relative to the instrument 9. The adjusting rod 8 is rotatably connected with a supporting ball 81 that abuts against the inner wall of the instrument 9 at one end away from the elastic shell 3. The supporting ball 81 is made of rubber. Since the experimenter manually puts the instrument 9 upside down on the first infusion shell 4, the instrument 9 will be offset from the first infusion tube 11. When the elastic shell 3 is propped up by the cleaning liquid, the adjusting rod 8 drives the supporting ball 81 to abut against the inner wall of the instrument 9, adjusts the distance between the elastic shell 3 and the side wall of the instrument 9, improves the coaxiality of the first infusion tube 11 and the instrument 9, facilitates the first bristles 31 to be in uniform contact with the inner wall of the instrument 9, and improves the cleaning effect of the first bristles 31 on the instrument 9.

[0040] Reference Figure 1 A feeding trough 12 is provided on the side wall of the cleaning shell 1 for the support frame 2 to pass through. A sealing plate 13 is hinged on the side wall of the cleaning shell 1 for closing the feeding trough 12. The sealing plate 13 prevents the cleaning liquid from overflowing the cleaning shell 1. After the instrument 9 is cleaned, the experimenter pulls the support frame 2 to overflow from the feeding trough 12 and out of the cleaning shell 1, thereby taking out the cleaned instrument 9.

[0041] The implementation principle of an experimental instrument cleaning device according to an embodiment of the present invention is as follows: the experimenter turns the instrument 9 upside down on the first infusion housing 4, injects cleaning liquid into the first infusion tube 11, and the cleaning liquid enters the elastic housing 3 through the first infusion hole 111, so that the elastic housing 3 is expanded in the instrument 9, and the first bristles 31 abut against the inner wall of the instrument 9. At the same time, the cleaning liquid in the first infusion tube 11 flows through the first infusion housing 4, and then the cleaning liquid is output from the second infusion hole 41 and the third infusion hole 42. The cleaning liquid output from the second infusion hole 41 drives the first infusion housing 4 to rotate around the central axis of the first infusion tube 11, and the second bristles 43 rotate synchronously with the first infusion housing 4. At the same time, the cleaning liquid is transported to the inner bottom wall of the instrument 9 through the third infusion hole 42, so that the second bristles 43 clean the inner bottom wall of the instrument 9.

[0042] Then the first linear drive 51 drives the fastening rod 5 to move downward, and the rotating ball 52 moves synchronously with the fastening rod 5 to abut against the outer bottom wall of the instrument 9. The rotating ball 52 squeezes the instrument 9 downward. At this time, the second bristles 43 are bent, so that the first infusion shell 4 can drive the instrument 9 to rotate around the central axis of the first infusion tube 11 through the second bristles 43, and then the instrument 9 rotates relative to the elastic shell 3. At the same time, the cleaning liquid output from the second infusion hole 41 flows downward to the inner wall of the instrument 9, thereby allowing the first bristles 31 to clean the inner wall of the instrument 9.

[0043] When the experimenter places the instrument 9 on the second bristle 43, the first linear actuator 51 moves the rotating ball 52 downward to press the instrument 9 through the fastening rod 5, and the first linear actuator 51 drives the second sliding frame 511 to move synchronously with the fastening rod 5, and the second sliding frame 511 drives the second liquid inlet pipe 512 and the second liquid infusion pipe 513 to move downward, so that the second liquid infusion pipe 513 is located on both sides of the instrument 9. The second liquid inlet pipe 512 transports the cleaning liquid to the second liquid infusion pipe 513, and the cleaning liquid is sprayed to the outer wall of the instrument 9 through the fourth liquid infusion hole 514, thereby cleaning the outer wall of the instrument 9.

[0044] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
