Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a detachable cell brush. Background Art
[0002] A cell brush is a tool widely used in biological and medical experiments. It is usually made of plastic or metal, with a slender handle and a brush head. The brush head is usually composed of a series of closely arranged filaments. It is mainly used to separate and purify cells, as well as to perform operations such as scraping or brushing cells.
[0003] Most of the existing cell brushes are divided into an integrated structure and a detachable structure. The brush head and the handle of the integrated cell brush are connected as a whole. Since it cannot be disassembled, once the brush head is worn or contaminated so seriously that it cannot be effectively cleaned, the entire cell brush needs to be discarded. The existing detachable cell brush usually has a stud at the position of the brush head, and the stud is threadedly connected to the handle to achieve the detachable assembly and disassembly of the brush head and the handle. This disassembly and assembly method requires the stud and the handle to be rotated multiple times before the brush head and the handle can be connected and fixed, which makes the user's efficiency when connecting the brush head and the handle relatively limited. Therefore, the utility model aims to provide a cell brush that is convenient for users to disassemble and assemble the brush head and the handle. Utility Model Content

[0028] Example: See Figures 1 to 8 According to an embodiment of the utility model, a technical solution is provided: a detachable cell brush comprises a head 1, a handle 2 and bristles 3 arranged on the head 1, and also comprises an inserting portion 4, which is arranged at the bottom of the head 1, and at least one limiting portion 5 is arranged on the peripheral side wall of the inserting portion 4, and the top of the handle 2 is recessed to form an inserting hole 6 suitable for the movable insertion of the inserting portion 4, and limiting grooves 7 corresponding to the number and position of the limiting portion 5 and suitable for the movement of the limiting portion 5 are opened in the inserting hole 6 along its length direction, and limiting ring grooves 8 suitable for the movement of the limiting portion 5 are opened in the inserting hole 6 along the circumference of the handle 2, and the limiting portion 5 is provided with a rubber portion 9, and the limiting ring groove 8 is provided with an orifice 10 suitable for the rubber portion 9 to be inserted.
[0029] For the detachable cell brush adopting the above structure, when the user needs to assemble the head 1 and the handle 2, first align the plug-in portion 4 on the head 1 with the plug-in hole 6 on the handle 2, then align the limiting portion 5 with the limiting groove 7, and then insert the plug-in portion 4 into the plug-in hole 6. At this time, the limiting portion 5 will move along the length direction of the limiting groove 7 until the bottom of the plug-in portion 4 is attached to the bottom of the plug-in hole 6. At this time, the head 1 is rotated to drive the plug-in portion 4 to rotate, and at the same time drive the limiting portion 5 to rotate in the limiting ring groove 8 until the rubber part on the limiting portion 5 is in the position. 9 is inserted into the hole 10 in the limiting ring groove 8 to limit the limiting part 5 from rotating relative to the limiting ring groove 8, and the assembly of the head 1 and the handle 2 can be completed. When the user needs to disassemble the head 1 and the handle 2, first, rotate the head 1 to drive the plug-in part 4 to rotate, and at the same time drive the limiting part 5 to rotate in the limiting ring groove 8 until the limiting part 5 is rotated into the limiting groove 7. At this time, pull the plug-in part 4 out of the plug-in hole 6 to complete the disassembly of the head 1 and the handle 2, which is convenient for the user to quickly install the head 1 and the handle 2.
[0030] In this embodiment, a plurality of friction-enhancing grooves 11 are provided on the head 1 at intervals along its circumference; when the user needs to turn the head 1, by holding the friction-enhancing grooves 11 on the head 1, the friction-enhancing grooves 11 will increase the friction between the user's palm and the head 1, making it easier for the user to turn the head 1.
[0031] In this embodiment, an annular gripping opening 12 is provided on the handle 2 along its circumference; when the user needs to hold the handle 2 for operation, the annular gripping opening 12 can provide a natural placement position for the user's fingers, thereby increasing the stability and comfort of holding.

[0033] In this embodiment, a magnetic suction groove 15 is provided inside the handle 2, and a magnetic suction component 16 suitable for adsorbing the plug-in part 4 is provided inside the magnetic suction groove 15; when the user puts the plug-in part 4 into the plug-in hole 6, the magnetic suction component 16 located in the magnetic suction groove 15 will generate an adsorption force on the plug-in part 4, so that the user can insert the plug-in part 4 into the plug-in hole 6.
[0034] In this embodiment, a magnetic suction cavity 17 is defined inside the rubber part 9, and a magnetic suction component 18 suitable for adsorbing the handle 2 is provided in the magnetic suction cavity 17; after the user inserts the rubber part 9 into the hole 10, the magnetic suction component 18 will adsorb the handle 2 so that the rubber part 9 can be more stably inserted into the hole 10.
[0035] Working principle: When the user needs to assemble the head 1 and the handle 2, first align the plug-in portion 4 on the head 1 with the plug-in hole 6 on the handle 2, then align the limiting portion 5 with the limiting groove 7, and then insert the plug-in portion 4 into the plug-in hole 6. At this time, the magnetic attraction member 16 located in the magnetic attraction groove 15 will generate an adsorption force on the plug-in portion 4, making it convenient for the user to insert the plug-in portion 4 into the plug-in hole 6. Then, the limiting portion 5 will move along the length direction of the limiting groove 7 until the plug-in portion 4 is inserted. The bottom of the handle 1 is attached to the bottom of the plug hole 6. At this time, the head 1 is rotated, and the friction increasing groove 11 on the head 1 is held. The friction increasing groove 11 increases the friction between the user's palm and the head 1, which is convenient for the user to rotate the head 1, so as to drive the plug-in part 4 to rotate, and at the same time drive the limit part 5 to rotate in the limit ring groove 8, until the rubber part 9 on the limit part 5 is stuck in the hole 10 in the limit ring groove 8. At this time, the magnetic suction part 18 will adsorb the handle 2 so that the rubber part 9 can It is more stably stuck in the hole 10 to limit the rotation of the limiting part 5 relative to the limiting ring groove 8. At this time, the assembly of the head 1 and the handle 2 is completed. When the user needs to disassemble the head 1 and the handle 2, first, rotate the head 1 to drive the plug-in part 4 to rotate, and at the same time drive the limiting part 5 to rotate in the limiting ring groove 8 until the limiting part 5 is rotated into the limiting groove 7. At this time, pull the plug-in part 4 out of the plug-in hole 6 to complete the disassembly of the head 1 and the handle 2, which is convenient for the user to quickly install the head 1 and the handle 2; when the user needs to hold the handle 2 for operation, the annular holding opening 12 can provide a natural placement position for the user's fingers, which increases the stability and comfort of holding; when the user needs to hang the handle 2, through the hanging hole 14, the user can use a thin rope, a hook or other hanging tools to hang the handle 2, which avoids the handle 2 being accidentally knocked over and causing the bristles 3 on the head 1 to be contaminated.
