Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, and in particular to an electric cleaning brush. Background Technology

[0002] Tubular instruments are commonly used in medicine, such as drainage tubes, test tubes, and non-disposable syringes. These instruments need to be cleaned and sterilized in a sterilization supply center after use. When cleaning instruments such as test tubes, medical staff usually hold the instrument with one hand and rinse it with clean water, while using the other hand to apply cleaning agent to a brush and insert it into the lumen for cleaning. When using the brush, the medical staff need to move the brush back and forth up and down and rotate it in both directions on the inner wall of the lumen to thoroughly clean the inner wall and prevent dirt from sticking to the inner wall and causing medical contamination.

[0003] However, this manual cleaning method has the following drawbacks: Since a large number of tubular instruments need to be cleaned every day, medical staff are prone to fatigue, soreness, or wrist strain when holding the brush and rotating it. Also, because the brush is fine, the brush may slip off when rotating it in both directions, making cleaning inconvenient.

[0004] Existing technologies have made improvements to this, such as the patent document with authorization announcement number CN 219025251 U, which discloses a cavity cleaner, which includes a main shell, a slider slidably connected to the upper side of the main shell, a rotating shaft rotatably connected to the slider in the left and right axial direction, a cleaning brush coaxially and detachably connected to the left end of the rotating shaft through the main shell, a spiral groove located to the left of the slider in the left and right direction on the rotating shaft, a fixed post in the upper side wall of the main shell in the upper and lower axial direction and inserted into the spiral groove, a rotating post located below the slider in the main shell in the front and back axial direction and rotatable, a swing rod in the upper and lower direction at the rear end of the rotating post, a waist-shaped groove in the upper and lower direction and through the front and back on the swing rod, and an insert post in the front end of the slider in the front and back axial direction and inserted into the waist-shaped groove.

[0005] The tube cleaner described in the aforementioned patent document can replace manual cleaning by rotating and brushing the inside of the tube. Compared to traditional manual brushing, it is simpler to operate and saves time and effort. However, the tube cleaner cannot add cleaning agent while brushing. After brushing a certain number of times, additional cleaning agent needs to be added to the brush head to effectively clean the inner wall of the tube. Therefore, it still has some inconvenience in use and reduces cleaning efficiency. Utility Model Content

Therefore, they should not be construed as limiting the scope of protection of this application.

[0018] To address the low cleaning efficiency of existing technologies, the inventors, after careful analysis, discovered that the main reason for this problem is the inability to spray cleaning agent simultaneously, requiring a pause in the cleaning process to refill the agent. Based on this analysis, the inventors have made structural improvements to the electric cleaning brush.

[0019] like Figure 1-4 As shown, an electric cleaning brush of this utility model includes a handle 1, a brush head 2, a liquid storage bottle 3, a press pump 4, and a rotating component 5.

[0020] The brush head 2 is rotatably mounted on one end of the handle 1. The handle 1 is equipped with a drive motor 11, which can be used to drive the brush head 2 to rotate and clean. The brush head 2 is hollow inside, and there are several small liquid outlet holes 21 at intervals on the side wall. The liquid storage bottle 3 is detachably mounted on the other end of the handle 1. The press pump 4 is mounted on the side wall of the handle 1. The liquid storage bottle 3 is connected to the brush head 2 and the press pump 4 through the liquid outlet hose 31 and the vent pipe 32, respectively. The press pump 4 can pump the cleaning agent in the liquid storage bottle 3 out through the small liquid outlet holes 21 on the side wall of the brush head 2.

[0021] The removable storage bottle 3 is used to store the cleaning agent. When in use, the cleaning agent in the single storage bottle 3 can be sprayed out from the outlet hole 21 through the outlet hose 31 by pressing the pump 4. This allows the cleaning agent to be added while brushing, thereby improving the cleaning efficiency.

[0022] One end of the handle 1 is provided with a bearing 12 and a connecting tube 13 along the axial direction. One end of the rotating part 5 is inserted into the bearing 12 and rotatably sleeved on the connecting tube 13. The other end is connected to the brush head 2. The two ends of the connecting tube 13 are respectively connected to the inside of the brush head 2 and the liquid outlet hose 31. A driven gear 51 is provided on the outer circumference of the rotating part 5. The drive motor 11 drives the rotating part 5 to rotate by meshing with the driven gear 51.

[0023] The drive motor 11 drives the rotating component 5 to rotate via the driven gear 51, which in turn drives the brush head 2 to rotate, thus achieving electric cleaning and reducing the burden on the manual wrist. The bearing 12 ensures the stability of the transmission. The rotating component 5 is rotatably fitted onto the connecting rigid tube 13, allowing the cleaning agent in the storage bottle 3 to flow out through the outlet hole 21 on the brush head 2 via the connecting rigid tube 13 while the rotating component 5 and the brush head 2 are rotating. Optionally, a sealing ring is fitted onto the connecting rigid tube 13 to prevent the cleaning agent from leaking from the connection point.

[0024] The brush head 2 includes a rubber strip 22 and bristles 23. The bristles 23 are evenly distributed on the outer side of the rubber strip 22 and are fixedly connected to the rubber strip 22. Because the rubber strip 22 is made of a flexible material, it can be bent at a small angle, making it suitable for cleaning the inner walls of some curved cavities.

[0025] The rubber strip 22 is detachably connected to the rotating component 5 via a threaded sleeve 24. One end of the rubber strip 22 has a boss 221, and the outer end of the boss 221 has a connecting post 222 communicating with the liquid outlet hole 21. A sealing ring is also fitted on the connecting post 222 to prevent cleaning agent leakage from the connection point. One end of the rotating component 5 has a groove 52 that matches the shape of the boss 221 and the connecting post 222. The boss 221, groove 52, and threaded sleeve 24 allow for quick assembly and disassembly between the brush head 2 and the rotating frame, enabling the replacement of different brush head models as needed.

[0026] The handle 1 is provided with a pressing chamber 14. The pressing pump 4 includes a pressing rod 41, a piston 42, a one-way valve 43 and a spring 44. The piston 42 is slidably disposed in the pressing chamber 14 and is fixedly connected to one end of the pressing rod 41. The other end of the pressing rod 41 extends out of the pressing chamber 14 and is provided with a pressing block 411. The pressing rod 41 is provided with a through groove 412 communicating with the outside. The one-way valve 43 is disposed in the through groove 412. The spring 44 is sleeved on the pressing rod 41 and its two ends abut against the pressing block 411 and the side wall of the handle 1, respectively.

[0027] When the pressing block 411 is pressed, the piston 42 compresses the air in the pressing chamber 14 and pressurizes the liquid storage bottle 3 through the vent pipe 32, thereby causing the cleaning agent in the liquid storage bottle 3 to be pumped out through the liquid outlet hose 31. After the pressing block 411 is released, the spring 44 returns to its original position, and external air enters the pressing chamber 14 through the one-way valve 43, thereby realizing continuous pumping.

[0028] The length of the outlet hose 31 extending into the storage bottle 3 is longer than the length of the vent hose 32 extending into the storage bottle 3, and a sediment block 311 is also provided at the end of the outlet hose 31 extending into the storage bottle 3. Because the outlet hose 31 is relatively long and has a sediment block 311 at its end, the end of the outlet hose 31 can always be immersed in the cleaning agent under the action of the sediment block 311, regardless of the position of the electric cleaning brush, thus avoiding pump interruption.

[0029] A control button 15 is provided on the outer wall of the handle 1, which can be used to control the start or stop of the drive motor 11. A battery 16 is provided inside the handle 1, and a charging port 17 for charging the battery 16 is provided at the lower end of the handle 1. A rubber plug 18 is provided on the charging port 17 to protect the charging port 17. The control button 15 is electrically connected to the battery 16 and the drive motor 11.

[0030] When using, select the corresponding model of brush head 2 as needed, and connect and install the brush head 2 to the rotating part 5 through the screw sleeve 24. Then, fill the cleaning agent into the storage bottle 3 and connect the storage bottle 3 to the handle 1. Press the control button 15 to start the drive motor 11, which drives the brush head 2 to rotate for cleaning the inner wall of the tube. At the same time, the cleaning agent in the storage bottle 3 can be pumped out through the infusion hose from the outlet hole 21 by pressing the pressing block 411 that extends out of the side wall of the handle 1. This allows for simultaneous addition of cleaning agent while rotating and brushing, improving cleaning efficiency.

[0031] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this utility model should be within the protection scope of this utility model.
