[0002] In the laboratory and medical fields, test tube cleaning is an indispensable part of daily research and testing work. Its cleaning efficiency and cleanliness directly affect the accuracy and reliability of experimental results. The traditional manual test tube cleaning method is not only time-consuming and laborious, but also difficult to ensure the consistency of cleaning quality, especially for a large number of test tubes or test tubes with complex structures and difficult to reach the inside, manual cleaning is particularly inconvenient.

[0003] However, some existing electric test tube brush designs often have problems such as insufficient connection stability, inconvenient disassembly and assembly, low cleaning efficiency, and insufficient protection of test tubes. For example, the connection between the brush head and the drive device in some designs is relatively simple, which is easy to loosen or even fall off during operation, affecting the cleaning effect; the steps for replacing the brush head are cumbersome and time-consuming, reducing work efficiency; during the cleaning process, if there are no effective measures to protect the test tube, it is easy to cause the test tube to be damaged or scratched under mechanical action, increasing costs; at the same time, there is a lack of effective protection mechanism to prevent the sewage after cleaning from flowing back to the handle, posing a potential risk to the user's hand health.

[0004] Therefore, it is necessary to provide a novel electric test tube brush to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a new electric test tube brush, which greatly simplifies the disassembly and assembly process, makes the brush head quick and convenient to replace, avoids the deviation of the brush head in the test tube, and effectively prevents the test tube from being damaged due to collision during high-speed rotation cleaning, while greatly improving the efficiency and thoroughness of cleaning.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The utility model provides a novel electric test tube brush, comprising:

[0026] A handle 1, in which a servo motor 14 is installed, a rotating shaft end of the servo motor 14 passes through the front end of the handle 1 and is fixedly connected to a mounting head 2, and a slot 9 is provided at the front end of the mounting head 2;

[0027] The connector 6 is arranged at the front end of the mounting head 2, the front end of the connector 6 is provided with a brush head 5, and the rear end of the connector 6 is fixedly connected with a clamping block 8 clamped in the clamping slot 9, and the outer wall of the connector 6 and the outer wall of the mounting head 2 are both provided with spiral threads;

[0028] The threaded sleeve 3 is threadedly connected to the connecting head 6 and the mounting head 2. The front end of the threaded sleeve 3 is provided with a protective sleeve 4 which is sleeved on the outside of the brush head 5. When the clamping block 8 is fully engaged in the clamping groove 9, the spiral threads on the outer wall of the connecting head 6 fit with the spiral threads on the outer wall of the mounting head 2. The threaded sleeve 3 is connected between the connecting head 6 and the mounting head 2 by rotating to tighten the connection between the connecting head 6 and the mounting head 2.

[0029] In the specific implementation process, Figure 2 As shown, both the block 8 and the slot 9 are cross-shaped structures, and a limit plate 7 is provided at the front end of the connector 6. Due to the characteristics of the block 8 and the slot 9 being cross-shaped structures, after the mounting head 2 and the connector 6 are connected, the two can be prevented from rotating, so as to ensure that the brush head 5 can clean the test tube.

[0030] In the specific implementation process, Figure 1 As shown, the protective sleeve 4 is designed as a trumpet-shaped structure, and one end of the limiting plate 7 passes through the protective sleeve 4. Through its design, it can ensure that the protective sleeve 4 wraps and protects one end of the test tube to prevent the test tube from colliding with other parts on the handle 1 and being damaged.

[0031] In the specific implementation process, Figure 3 As shown, a first rubber ring 10 is bonded to the inner wall of the rear end of the protective sleeve 4, and a second rubber ring 11 is bonded to the inner wall of the front end of the protective sleeve 4. The first rubber ring 10 can contact the end face of the test tube and provide elastic protection for it, while the second rubber ring 11 can make soft contact with the outer wall of the test tube mouth, so that the protective sleeve 4 can provide good protection for the test tube, prevent the test tube from being damaged when cleaning the test tube, and improve safety performance.

[0032] In the specific implementation process, Figure 1 As shown, the outer wall of the handle 1 is fixedly connected to an outer shell 12, and one end of the outer shell 12 is provided with a plurality of storage openings 13 for storing the brush heads 5. The outer shell 12 can be conveniently stored with a certain number of brush heads 5, so that they can be taken out and replaced at any time when replacement is needed.

[0033] The outer shell 12 is designed in a semicircular arc structure, and the side of the outer shell 12 is designed in an arc structure. The shape and structure of the outer shell 12 can fit the shape and structure of the handle 1 to prevent inconvenience in the handling operation of the handle 1. At the same time, the arc design of the side of the outer shell 12 can prevent its side from being too sharp and causing safety accidents during actual operation.

[0034] The working principle of a new type of electric test tube brush provided by the utility model is as follows: the brush head 5 is installed on the handle 1, and the specific process is to insert the block 8 at the tail end of the connector 6 at one end of the brush head 5 into the slot 9, so that the connector 6 fits with the mounting head 2, and the connection between the slot 9 and the block 8 can prevent the connector 6 and the mounting head 2 from rotating, then the threaded sleeve 3 initially located on the mounting head 2 is rotated and moved between the mounting head 2 and the connector 6, so that the mounting head 2 and the connector 6 are connected, and the threaded sleeve 3 is tightened to fit the limit plate 7, and when the electric test tube brush is needed to clean the test tube, The brush head 5 is inserted into the test tube, and the protective sleeve 4 at one end of the threaded sleeve 3 wraps one end of the test tube. The first rubber ring 10 in the threaded sleeve 3 and the first rubber ring 10 maintain soft contact with the test tube, so that the protective sleeve 4 and the test tube maintain a fit state, and then the servo motor 14 in the handle 1 is started to drive the brush head 5 to rotate stably in the test tube to clean the inside. After cleaning, the servo motor 14 is turned off and the brush head 5 is taken out of the test tube. The protective sleeve 4 can prevent the residual liquid of the brush head 5 from flowing to the handle 1 and causing adverse effects on human hands, that is, the use process of the electric test tube brush is completed.

[0035] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
