Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, specifically to a volumetric flask cleaning brush. Background Technology

[0002] In the analysis of geochemical survey samples, volumetric flasks are commonly used precision measuring instruments for accurately preparing standard solutions, quantitatively diluting samples, or storing standard solutions. The thoroughness of their cleaning directly affects the quality of the sample analysis data.

[0003] Because volumetric flasks typically have long, narrow necks and small openings, reagents, solvents, or sediments can easily remain inside. Traditional cleaning methods, such as manual shaking, soaking, or using a regular bottle brush, are often insufficient to thoroughly clean the walls and bottom of the flasks, especially for smaller volumetric flasks. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This volumetric flask cleaning brush, with its built-in telescopic rod, flexibly extends the cleaning range, reaching deep into the interior of volumetric flasks with narrow necks and openings. It effectively reaches areas on the flask walls and bottom that are difficult to reach with traditional cleaning methods, thoroughly removing residual reagents, solvents, and precipitates. Simultaneously, the ingenious combination of the brush head and connector allows the bristles to closely conform to the flask wall, achieving comprehensive and thorough cleaning, greatly improving cleaning effectiveness and ensuring the accuracy of sample analysis data.

[0018] This volumetric flask cleaning brush features a connector with a locking block, spring, limiting groove, and fixing groove, making the connection and disassembly of the brush head and telescopic rod simple and convenient.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a volumetric flask cleaning brush, comprising:

[0028] The receiving rod 4 is hollow and houses the motor and telescopic rod 5. The telescopic rod 5 can be extended outward to extend the cleaning range of the device. The receiving rod 4, together with the telescopic rod 5, extends the cleaning range. The receiving rod 4 is connected to a handle 2 for convenient operation of the device. The handle 2 is hollow and has a battery compartment 21 at the top. The battery compartment 21 houses the battery, which drives the motor in the receiving rod 4. The entrance of the battery compartment 21 is covered with a cover 1. The receiving rod 4 also has a motor compartment door 41, which houses the motor. The battery compartment 21 is connected to the motor, thereby driving the motor to operate and generate vibration to enhance the cleaning ability of the device. There is at least one telescopic rod 5, and the telescopic rod 5 is hollow. The hollow design allows for the internal placement of a smaller telescopic rod 5.

[0029] The snap-fit ​​cap 3 is provided on the snap-fit ​​cap 7. The snap-fit ​​cap 3 is used to cover the mouth of the container to prevent the cleaning liquid from splashing out during cleaning. It is used to seal the mouth of the volumetric bottle. The snap-fit ​​cap 3 has a vessel rim 31 on the side near the brush head 7. The vessel rim 31 is used to snap into the mouth of the container, so as to seal the container more tightly. There is at least one vessel rim 31. The other vessel rims 31 are ring-shaped and fitted on the snap-fit ​​cap 3. This can accommodate containers of different diameters as much as possible.

[0030] Connector 6 is used for easy connection and disassembly of brush head 7. Connector 6 is located at one end of telescopic rod 5 and is used to connect brush head 7. Brush head 7 is used to clean the inner wall of container. Connector 6 includes a support base 610 located on telescopic rod 5. Support base 610 is used to support receiving chamber 67 and spring 68. Receiving chamber 67 is provided on support base 610. Receiving chamber 67 is used to accommodate locking block 61 and allows locking block 61 to slide into receiving chamber 67. Spring 68 is provided inside receiving chamber 67 and spring 68 is used to lock block 61. Pulling 61 allows the locking block 61 to slide into the receiving chamber 67, after which the locking block 61 is pushed back to its original position. The spring 68 is connected to the locking block 61. The locking block 61 is used to connect the brush head 7 and the telescopic rod 5. The locking block 61 is pushed back to its original position by the spring 68 to lock the brush head 7. The locking block 61 has a limit groove 63 and a fixing groove 64. The inner dimension of the limit groove 63 matches the outer dimension of the limit strip 65, and the inner dimension of the fixing groove 64 matches the outer dimension of the connecting handle 72. The bottom of the locking block 61 is connected to a limit sleeve 62.

[0031] The support base 610 is provided with a sliding groove 69, which is used to accommodate the limiting sleeve 62. When the limiting sleeve 62 is fitted into the sliding groove 69, the locking block 61 is limited. The sliding groove 69 is provided with a limiting strip 65, which is inserted into the limiting groove 63. The limiting strip 65 is provided with a plug-in block 66.

[0033] When using the volumetric flask cleaning brush, first open the cap 1 at the inlet of the battery compartment 21 and insert the battery to power the motor inside the motor compartment door 41 of the receiving rod 4. Depending on the depth of the volumetric flask, extend the hollow telescopic rod 5 inside the receiving rod 4; the multi-level nested structure further extends the cleaning range. Insert the annularly fitted container 31 on the snap-on cap 3 into the mouth of the volumetric flask to achieve a seal and prevent cleaning fluid from splashing. When installing the brush head 7, press the locking block 61 to allow it to slide into the receiving compartment 67 of the support base 610 against the spring force of the spring 68. Insert the connecting handle 72 of the brush head 7 into the support base 610. When the connecting handle 72 reaches the designated position, the insertion block 66 on the limiting strip 65 inserts into the insertion hole 721 of the connecting handle 72. Simultaneously, the locking block 61 resets under the traction of the spring 68, and its fixing groove 64 locks the connecting handle 72, completing a secure connection. After starting the motor, the operator holds the handle 2 to control the receiving rod 4 and the telescopic rod 5, which drives the brush head 7 into the volumetric flask. The brush bristles 71 adhere to the inner wall, and the cleaning is completed under the combined action of motor vibration and manual operation. After the cleaning is finished, the brush head 7 can be removed by pressing the locking block 61 again.
