Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to an automatic cleaning tool brush for cleaning a rotary distillation flask. Background Art

[0002] Since the 1970s, the sub-discipline of molecular organic geochemistry has rapidly developed thanks to the advent and widespread adoption of analytical techniques such as chromatography and chromatography-mass spectrometry. Biomarker compounds can now be detected in extracts from petroleum and source rocks, revealing a wide range of information, including the source of organic matter, the environment and water bodies in which it is deposited, its preservation conditions, secondary geological processes (such as biodegradation, evaporative fractionation, and gas washing), and its age. Rotary evaporation involves electronically controlling the constant rotation of a flask at an optimal speed to maximize the evaporation area. A vacuum pump maintains a negative pressure in the evaporating flask, which is then heated in a water bath. Under this negative pressure, the solution evaporates and heats within the rotating flask, achieving separation and purification. Rotary evaporation offers advantages such as speed, safety, efficiency, and ease of operation. It is widely used in experiments for extract concentration and chromatographic separations, providing significant advances in petroleum geology and geochemistry.

[0003] During rotary evaporation, the extract is placed in a flask and concentrated by the rotary evaporator. The biomarker extraction process is highly susceptible to contamination from external substances and is time-consuming, including the cleaning of glassware. The flask is the most important glassware in the rotary evaporation pre-treatment process. Traditional flask cleaning tools primarily rely on upright brushes or large bristles, which are difficult to conveniently access and effectively clean the inner wall of the flask. This is labor-intensive and difficult to completely clean. Utility Model Content

[0028] Example 1

[0029] like Figure 1-Figure 5 As shown:

[0030] An automatic cleaning tool brush for cleaning a rotary evaporation flask comprises a handle 1, a brush handle 4 and a brush head 5. The brush handle 4 is arranged in the middle position. The handle 1 and the brush head 5 are connected through the brush handle 4. The brush handle 4 is hollow, and one end of the brush handle 4 is fixed to the front end of the handle 1.

[0031] The handle 1 includes a shell 11, a bracket 12 is provided in the shell 11, a circuit board 21 is provided on the upper surface of the bracket 12, a placement groove is provided on the lower surface of the bracket 12, and a battery 22, a motor 23 and a retractable component 3 are installed in the placement groove.

[0032] A reducer 24 is also provided in the placement slot. The output end of the motor 23 is connected to the rotating shaft 27 through the reducer 24 . The battery 22 is provided on a side of the motor 23 away from the reducer 24 .

[0033] The battery 22 is electrically connected to the circuit board 21 , the motor 23 , the reducer 24 and the driving components of the retractable assembly 3 .

[0034] A rear cover 13 is provided at the rear end of the housing 11 . The rear cover 13 is provided with a charging port 14 electrically connected to the battery 22 .

[0035] A front hole is formed at the front end of the handle 1 , and the rotating shaft 27 passes through the front hole and enters the interior of the brush handle 4 .

[0036] One end of the rotating shaft 27 away from the reducer 24 passes through the brush handle 4 and extends to the outside of the brush handle 4 to be connected to the brush head 5 . The rotating shaft 27 is rotatably connected to the brush handle 4 .

[0037] The retractable assembly 3 is mounted on the rotating shaft 27 and rotates synchronously with the rotating shaft 27 .

[0038] like Figure 3 As shown, the retracting and unfolding assembly 3 includes a small winch 31 and a micro motor 32 for driving the small winch 31 to rotate. The small winch 31 and the micro motor 32 are installed on the rotating shaft 27 through a mounting frame 35. The small winch 31 is provided with a storage groove 34 for winding the traction rope 33.

[0039] The small winch 31 is connected to the mounting frame 35 through a support column. The small winch 31 is rotatably connected to the support column so that the small winch 31 can rotate under the drive of the micro motor 32 to retract and release the traction rope 33.

[0040] The circuit board 21 is provided with a rotation button switch 25 electrically connected to the motor 23 and a retractable button switch 26 electrically connected to the micro motor 32 . The micro motor 32 is electrically connected to the battery 22 via the retractable button switch 26 .

[0041] The rotary button switch 25 has two gears, namely start and stop; the retractable button switch 26 has three gears, namely retract, stop and release.

[0042] The outer sleeve of the bracket 12 is provided with a first installation kit and a second installation kit located in the shell 11. The first installation kit and the second installation kit are both composed of an annular fixing sleeve 28 and a sealing soft rubber sleeve 29 located at both ends of the fixing sleeve 28. The fixing sleeve 28 of the first installation kit is provided with a rotation button 16, and the fixing sleeve 28 of the second installation kit is provided with a retractable button 17.

[0043] The rotation button 16 is located above the rotation button switch 25 , and the retractable button 17 is located above the retractable button switch 26 .

[0044] Two through holes 15 are defined in the housing 11 of the handle 1 . A rotation button 16 and a retractable button 17 respectively pass through the two through holes 15 and extend to the outside of the housing 11 .

[0045] The brush head 5 includes an elastic steel wire body 51 , and bristles 53 are wrapped around the body 51 .

[0046] The outer end of the rotating shaft 27 is fixedly connected to a point on the brush head 5 . A movable ring 52 is provided on the brush head 5 at a position opposite to the fixed point of the rotating shaft 27 and is sleeved on the outside of the rotating shaft 27 and slidably connected to the rotating shaft 27 .

[0047] One end of the traction rope 33 passes through the brush handle 4 and extends to the outside to be connected to the movable ring 52. The other end of the traction rope 33 is installed on the small winch 31. When the small winch 31 is driven by the micro motor 32 to retract and extend the traction rope 33, the movable ring 52 can be driven by the traction rope 33 to slide back and forth along the rotating shaft 27 to realize the deformation of the brush head 5.

[0048] The initial state of the device is as follows Figure 4 As shown, when the flask needs to be cleaned, the operator presses the retracting position of the retracting button 17 to control the micro motor 32 to work, the micro motor 32 rotates forward, and the small winch 31 reels the traction rope 33.

[0049] like Figure 5 As shown, the traction rope 33 pulls the movable ring 52 downward, and the brush head 5 changes from a circular ring to an elliptical ring. The operator inserts the brush head 5 into the flask.

[0050] The operator presses the release position of the retraction button 17 to control the micro motor 32 to work, the micro motor 32 reverses, and the small capstan 31 releases the traction rope 33. Under the action of the recovery deformation of the elastic steel wire body 51 of the brush head 5, the body 51 will drive the movable ring 52 to reset, and the traction rope 33 will not limit this process.

[0051] When the brush head 5 changes from an elliptical ring to a circular ring, the operator presses the start position of the rotation button 16 to control the motor 23 to operate. The motor 23 drives the rotating shaft 27 to rotate the brush head 5, thereby cleaning the interior of the flask. During this process, the retractable assembly 3 rotates synchronously with the rotating shaft 27, preventing the traction rope 33 from being entangled in the movable ring 52 or the rotating shaft 27, which restricts the rotation of the rotating shaft 27.

[0052] A limiting sleeve 6 is provided on the rotating shaft 27 located in the middle of the brush head 5 to prevent the movable ring 52 from being over-reset and to prevent the brush head 5 from being separated from the traction rope 33 at the moment of recovering its deformation.

[0053] Example 2

[0054] like Figure 6 As shown, in this embodiment, a support tube 71 installed on the bracket 12 is provided outside the retractable component 3, and the retractable component 3 is arranged in the support tube 71.

[0055] An annular guide groove 72 is provided on the side wall of the support tube 71 , and a T-shaped slider 73 is installed on the outer side surface of the mounting bracket 35 near the inner wall of the support tube 71 . The slider 73 is slidably disposed in the guide groove 72 .

[0056] The guide groove 72 and the slider 73 can provide support for the retractable assembly 3, preventing the shaft 27 from being deformed by the gravity of the retractable assembly 3, and preventing the shaft 27 from being deflected by the gravity of the retractable assembly 3 during long-term rotation.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
