Description

Technical Field

[0001] This utility model relates to the field of cleaning brush technology, and in particular to a detachable sample grinder cleaning brush. Background Technology

[0002] Drug sample grinders play a vital role in drug research and development, quality testing, and other fields. They can process drug samples efficiently and accurately, grinding drugs into fine and uniform powders or slurries in a short time, so that the samples reach the ideal state required for analysis and testing.

[0003] After use, pharmaceutical sample grinders require cleaning and maintenance. Existing cleaning tools generally use cleaning brushes, but the brush heads are usually fixed and cannot be disassembled and replaced. This makes it easy for dirt to accumulate on the brush during use, affecting the subsequent cleaning effect. The brushes also cannot be adjusted, making it difficult to fully cover and thoroughly clean the complex structure and narrow space inside the pharmaceutical sample grinder, which is quite inconvenient.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1

[0036] This utility model provides, for example Figure 1-3 The detachable sample grinder cleaning brush shown includes a brush handle 1, a cleaning brush head 3, a locking mechanism 4, and an adjustment mechanism 5. A mounting bracket 2 is rotatably mounted on the bottom of the brush handle 1 via a pivot. The cleaning brush head 3 is slidably mounted inside the mounting bracket 2. The locking mechanism 4 is located inside the mounting bracket 2 for multi-point positioning of the cleaning brush head 3. The adjustment mechanism 5 is located inside the brush handle 1 for adjusting the angle of the cleaning brush head 3. The locking mechanism 4 allows the cleaning brush head 3 to be disassembled promptly after wear or excessive dirt accumulation, preventing incomplete cleaning and cross-contamination, and reducing usage costs. The adjustment mechanism 5 allows for flexible adjustment of the cleaning brush head 3's angle, adapting it to the complex structure of the grinder, achieving multi-directional cleaning, and improving cleaning efficiency and versatility.

[0037] Specifically, the locking mechanism 4 includes a bidirectional screw 41, a locking rod 42, and a sliding rod 43. The top of the inner wall of the mounting bracket 2 is symmetrically provided with adjustment grooves. The end of the bidirectional screw 41 is slidably inserted into the inner wall of the adjustment groove. The locking rod 42 is symmetrically arranged inside the adjustment groove, forming a screw drive with the bidirectional screw 41. The cross-section of the locking rod 42 is L-shaped. The top of the cleaning brush head 3 is symmetrically provided with locking grooves for engaging the locking rod 42. The end of the sliding rod 43 is fixedly connected to the inner wall of the adjustment groove. The locking rod 42 and the sliding rod 43 are slidably inserted into each other. Rotation of the bidirectional screw 41 can drive the two locking rods 42 to move closer or further apart, allowing the locking rod 42 to engage with the locking groove on the cleaning brush head 3, thus enabling the installation of the cleaning brush head 3. When the cleaning brush head 3 accumulates a lot of dirt or wears excessively, it can be disassembled by rotating the bidirectional screw 41 in the opposite direction, and a new cleaning brush head 3 can be replaced for continued use.

[0038] Specifically, the adjustment mechanism 5 includes a rotating rod 51, a first gear 52, a second gear 53, and a positioning component 54. The rotating rod 51 is rotatably mounted inside the brush handle 1 via a bearing. The first gear 52 is fixedly inserted into the rotating shaft. The second gear 53 is fixedly connected to one end of the rotating rod 51. The first gear 52 and the second gear 53 are meshed together. The positioning component 54 is located inside the brush handle 1 and is used to position the rotation of the first gear 52. By releasing the positioning component 54 from the rotating rod 51, the second gear 53 can be rotated by the rotating rod 51. This allows the cleaning brush head 3 on the mounting bracket 2 to rotate via the first gear 52. This allows the mechanism to adapt to the complex internal structure of the pharmaceutical sample grinder and can be used flexibly when cleaning corners, crevices, or specially shaped parts of the grinder is required.

[0039] Example 2

[0040] Based on Example 1, such as Figure 4As shown, the positioning assembly 54 includes a sleeve 541, a fixing plate 542, a pull plate 543, a positioning rod 544, and a compression spring 545. The sleeve 541 is sleeved on the outside of the rotating rod 51. The fixing plate 542 is fixedly connected to the other end of the rotating rod 51 and is located inside the sleeve 541. The pull plate 543 is fixedly connected to one end of the sleeve 541. A groove is provided at one end of the brush handle 1. The pull plate 543 is slidably inserted into the inner cavity of the groove. One end of the positioning rod 544 is fixedly connected to the pull plate 543. Positioning holes are provided at equal intervals on the inner wall of the groove. Multiple positioning holes are arranged in a... The ring-shaped positioning rod 544 has one end slidably inserted into the inner cavity of the positioning hole. The compression spring 545 is sleeved on the outside of the rotating rod 51. One end of the compression spring 545 is fixedly connected to the fixing plate 542, and the other end of the compression spring 545 is fixedly connected to the inner wall of the sleeve 541. The compression spring 545 provides a stable elastic force to the pull plate 543 on the sleeve 541. The positioning rod 544 can be stably inserted into the positioning hole, so that the rotating rod 51 will not easily rotate during normal use, ensuring the stability of the cleaning brush head 3 after rotation adjustment.

[0041] Furthermore, a rubber sleeve 6 is fixedly fitted on the outer wall of the brush handle 1. The outer wall of the rubber sleeve 6 has anti-slip texture. The anti-slip texture increases the friction between the rubber sleeve 6 and the hand, allowing the operator to better grip the brush handle 1 and apply force, so that the cleaning brush head 3 can perform cleaning operations.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
