The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
The utility model is described in detail below by reference to the attached drawings and in connection with the embodiments:
Example 1:
As shown in fig. 1 to 2, this embodiment provides a multifunctional experimental brush with a replaceable brush head 1, which comprises a brush head 1 and a brush handle 3, and further comprises a replacement part 2, wherein one end of the replacement part 2 is fixed with the brush head 1, the other end of the replacement part is detachably connected with the brush handle 3 through a clamping piece 4, and the brush handle 3 is a spherical handle. Because the service life of the test tube brush is not long, PPS plastic can be used as the material of the brush handle 3 in order to save the cost, and PPS has the characteristics of high temperature resistance, corrosion resistance, stable size, high rigidity and the like, and is very suitable for being used in laboratory environment. The spherical handle has larger gripping area and larger stress surface when in use
Alternatively, the end of the brush head 1 is provided in a ball shape, and the bristles are tightly wound around the brush head 1 along the outer wall of the brush head 1. The brush head 1 of the conventional common test tube brush is not wrapped, but only some bristles are mixed in the middle of the iron rod, and the bristles are generally longer, so that the bristles are easy to branch off and cannot keep the original shape. In the embodiment, the brush head 1 is made into a sphere shape (similar to the end part of a toilet brush), the density of bristles is increased, the length of the bristles is controlled, the contact surface between the brush head 1 and the bottom of a test tube is larger, and the bottom of the test tube is fully washed. The short bristle length makes the overall form of the brush head 1 easier to maintain, reducing the wear of the test tube brush.
Specifically, the clamping piece 4 comprises a pressing block 41 and a reset spring 42, wherein two ends of the reset spring 42 are respectively fixed on the pressing block 41 and the inner wall of the brush head 1, a clamping groove is formed in the side wall of the end part of the replacement part 2, the end part of the brush handle 3 is hollow, a pressing hole 31 matched with the pressing block 41 is formed in the side wall of the end part of the brush handle 3 in the hollow tubular shape, the pressing block 41 is clamped in the clamping groove, and the pressing block 41 passes through the pressing hole 31 to protrude outwards from the side wall of the end part of the hollow tubular shape of the brush handle 3 in the natural state of the reset spring 42. Alternatively, two pressing blocks 41 are provided, the two pressing blocks 41 are symmetrically arranged on the side wall of the end part of the replacing part 2, correspondingly, two opposite clamping grooves are formed on the side wall of the end part of the replacing part 2, the two pressing blocks 41 are symmetrically clamped on the side wall of the replacing part 2, and two ends of a reset spring 42 are respectively fixed on the two pressing blocks 41. Alternatively, the pressing block 41 may be square or circular arc. The circular arc-shaped pressing block 41 more easily separates the brush holder 3 from the replacement part 2.
It should be noted that the diameter of the end of the brush holder 3 is slightly larger than the diameter of the replacement part, and the replacement part 2 may be sleeved with the replacement part, and the length of the two pressing blocks 41 is larger than the diameter of the end of the brush holder 3 in the natural state of the return spring 42, but when the pressing blocks 41 are pressed downwards, the diameter of the replacement part 2 and the length of the two pressing blocks 41 are larger than the diameter of the end of the brush holder 3 (i.e. the distance between the two pressing holes 31) after the return spring 42 is compressed, so that the brush holder 3 and the replacement part 2 can be separated after the pressing blocks 41 are pressed, and meanwhile, the spring needs to be ensured to clamp the brush holder 3 in the natural state, so that the brush holder 3 is fixedly connected with the replacement part 2 and does not fall off.
Alternatively, the engaging members 4 of the refill 2 and the handle 3 may be screw-threaded. The outer wall of the end part of the replacement part 2 is provided with external threads, the inner wall of the hollow tubular end part of the brush holder 3 is provided with internal threads matched with the external threads, and the replacement part 2 can be conveniently separated from the brush holder 3.
Example 2
The difference between this embodiment and embodiment 1 is that in embodiment 1, the replacement part 2 and the brush head 1 may be replaced by separating the replacement part 2 and the brush head 1 integrally from the brush handle 3, in this way, if the replacement part 2 is damaged, the replacement part 2 may cause resource waste, so in this embodiment, the fixed connector of the brush head 1 and the brush head 1 of the replacement part 2 is provided, so that only the part of the brush head 1 may be replaced conveniently, thereby saving the resource for replacing the replacement part 2.
Specifically, as shown in fig. 3, the brush head fixing member 5 is mounted inside the replacement part 2, and includes an elastic member 51, two clamping members 52, and a hook 53 fixedly connected to the hanging ring of the brush head 1, each clamping member 52 includes a free end and a fixed end, the fixed ends of the two clamping members 52 are connected to the ends of the hook 53, the free ends of the clamping members 52 are located outside the replacement part 2, and two ends of the elastic member 51 are respectively fixed to the two clamping members 52. The elastic member 51 may be a spring, and the free ends of the clamping members 52 are respectively provided with a bending section bending towards the direction of the brush holder 3, and the bending sections of the two clamping members 52 respectively extend out from two sides of the end part of the replacing part 2 to fix the brush head fixing member 5 inside the replacing part 2. The bending section is close to the outer wall of the replacement part 2, which is equivalent to hanging the whole brush head fixing piece 5 inside the replacement part 2, the clamping pieces 52 are clamped at the ports of the replacement part 2 under the natural state of the elastic pieces 51, and when the brush head 1 needs to be replaced, the bending section is pressed, so that the elastic pieces 51 are compressed, and the hooks 53 are pulled out of the replacement part 2.
The use flow of this embodiment is as follows:
When the replacement part 2 and the brush head 1 need to be replaced, the pressing block 41 is pressed downwards, so that the pressing block 41 is lower than the pressing hole 31, the brush handle 3 and the replacement part 2 are separated, and the new brush head 1 and the new replacement part 2 need to be replaced. When only the brush head 1 is to be replaced, the curved section can be pressed, thereby compressing the elastic member 51 and pulling the hook 53 out of the refill 2. The brush head 1 to be replaced is removed, the hanging ring at the end part of the new brush head 1 is fixed on the hanging hook 53, the clamping piece 52 is pressed, the hanging hook 53 and the upper part of the clamping piece 52 are placed in the replacing part 2, the clamping piece 52 is released at a proper position, and the elastic piece 51 is tensioned, so that the clamping piece 52 is fixed inside the replacing part 2. The application can match different kinds of brush heads 1 with the brush handle 3, and can replace the brush heads 1 to realize different functions, such as test tube brush, measuring cylinder brush, beaker brush and the like.
It is to be understood that the above embodiments are merely illustrative of the application of the principles of the present utility model, but not in limitation thereof. Various modifications and improvements may be made by those skilled in the art without departing from the spirit and substance of the utility model, and are also considered to be within the scope of the utility model.
