Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric cleaning, in particular to a reciprocating electric cleaning brush. Background Art
[0002] Most electric cleaning brushes currently on the market work by rotating the brush head with a rotating motor to clean the surface of an object. The brush head rotates around a fixed axis, just like the brush head of a traditional rotary mop or electric toothbrush. The rotary cleaning brush generates centrifugal force and friction through the high-speed rotation of the brush head, thereby achieving the purpose of cleaning. This rotational motion can quickly cover the cleaning surface, but the cleaning effect is relatively weak for some uneven surfaces, corners, or narrow areas. At the same time, when using a rotary cleaning brush, due to the high-speed rotation of the brush head, a large centrifugal force may be generated, requiring the user to hold the handle with greater force to maintain stability. In addition, the noise of the rotary cleaning brush is relatively loud, which can easily make people feel uncomfortable after long-term use, increasing the user's fatigue. Utility Model Content

The worm connecting seat is fixedly arranged in the shell, and the sliding member is slidably arranged in the shell. One end of the connecting shaft is connected to the output shaft of the drive motor, and the other end is connected to the driving worm. The driving worm is rotatably connected to the sliding member, and the end of the sliding member away from the drive motor is fixedly connected to the brush head shaft. The driving worm is used to drive the sliding member to reciprocate axially along the output shaft of the drive motor in the shell.
[0007] As a preferred solution, the driving worm is a bidirectional worm, which is threadedly connected to the worm connecting seat. A through groove is provided inside the worm connecting seat, and the driving worm is threadedly passed through the through groove. A through hole is provided at the end of the sliding member away from the driving motor, and the end of the driving worm away from the driving motor passes through the through hole, and the end has a flange, the diameter of the flange and the diameter of the driving worm are both larger than the diameter of the through hole, and the bidirectional worm is threadedly passed through the through groove.

[0016] 1. The reciprocating motion makes it relatively easy to control the direction of the cleaning brush during use. The user only needs to apply a little force to control its direction.

[0017] 2. The brush head makes a reciprocating motion, imitating ergonomic cleaning actions when working, similar to the back-and-forth wiping action of manual brushing, which can repeatedly wipe and impact stains. For areas with heavy oil pollution such as kitchen stoves and range hoods, or scale and dirt in the bathroom, the reciprocating electric cleaning brush can more effectively remove stubborn stains. When cleaning objects or areas with irregular shapes and many corners, it can better adapt to complex shapes to ensure that there are no dead angles in cleaning, such as the corners of sinks and the gaps between faucets.
[0018] 3. Compared with rotary electric cleaning brushes, the brush head does not need to move too fast, so the motor speed can be reduced, thereby reducing the noise of the device;
[0019] 4. Compared with the rotary electric cleaning brush, the reciprocating electric cleaning brush has relatively less wear on the surface of the object. Especially for some objects with fragile or easily worn surfaces, the use of a reciprocating cleaning brush can reduce damage to the surface of the object.

[0040] Furthermore, the reciprocating mechanism 50 is connected to the drive motor 30 through the connecting shaft 40. The reciprocating mechanism 50 includes a sliding member 51, a driving worm 52 and a worm connecting seat 53. The worm connecting seat 53 is fixedly arranged in the housing 10, and the sliding member 51 is slidably arranged in the housing 10. One end of the connecting shaft 40 is connected to the output shaft of the drive motor 30, and the other end is connected to the driving worm 52. The driving worm 52 is rotatably connected to the sliding member 51. The end of the sliding member 51 away from the drive motor 30 is fixedly connected to one end of the brush head shaft 20. The driving worm 52 is used to drive the sliding member 51 to reciprocate along the output shaft of the drive motor 30 in the housing 10. In other embodiments, the connecting shaft 40 can be the output shaft of the drive motor 30. The connecting shaft 40 is in the shape of a spline shaft, and the end of the output shaft away from the drive motor 30 is connected to the driving worm 52; through the cooperation of the sliding member 51, the driving worm 52 and the worm connecting seat 53, the brush head shaft 20 is driven to reciprocate.
[0041] Example 1, as Figure 1-Figure 5 As shown, the driving worm 52 is a bidirectional worm, which is screwed together with the worm connecting seat 53. A through groove 533 is provided inside the worm connecting seat 53, and the driving worm 52 is screwed through the through groove 533.

[0042] Furthermore, the sliding member 51 is barrel-shaped, with its opening facing the drive motor 30, and the sliding member 51 is sleeved on the outer periphery of the worm connecting seat 53. The outer wall of the worm connecting seat 53 is provided with a limiting slide 532, and the inner wall of the sliding member 51 is provided with a limiting slider corresponding to the limiting slide 532, thereby preventing the sliding member 51 from rotating under the drive worm 52.

In other embodiments, the drive worm 52 can also be periodically rotated forward and reversed by other structures or methods, such as setting a driver to make the drive motor 30 periodically rotate forward and reverse, or by setting a periodic forward and reverse gear set in the gear box 60. The drive worm 52 is an ordinary worm, and the gear box 60 drives the drive worm 52 to rotate forward and reverse periodically, thereby driving the sliding member 51 to reciprocate. The structure of the reduction gear set and the periodic forward and reverse gear set is prior art and will not be repeated here.
[0044] Example 3, as Figure 6-Figure 8 As shown, the sliding member 51 is barrel-shaped, with its opening facing the drive motor 30.

One end of the clamping block 54 is fixed to the sliding member 51, and the other end is embedded in the thread of the driving worm 52. The worm connecting seat 53 is provided with an avoidance groove 531 for avoiding the clamping block 54. The avoidance groove 531 extends along the length of the driving worm 52. During operation, the driving worm 52 rotates in the worm connecting seat 53, driving one end of the clamping block 54 to slide in the thread of the driving worm 52 and the other end to move along the extension direction of the avoidance groove 531, thereby driving the sliding member 51 to reciprocate.

[0047] Furthermore, an opening 11 is provided at one end of the shell 10 away from the driving motor 30, and a linear bearing 12 is provided inside the opening 11. The brush head shaft 20 is passed through the linear bearing 12. The linear bearing 12 can prevent the brush head shaft 20 from wearing the opening 11 after a long time, thereby reducing the shaking of the cleaning brush 70 during use.
[0048] Furthermore, a battery 13 is provided in the housing 10 , and the battery 13 is electrically connected to the driving motor 30 , thereby improving portability for users.
[0049] Furthermore, a control circuit board 14 is provided in the shell 10, and a control button 15 and a charging port 16 are provided on the shell 10.

[0050] Furthermore, a cleaning brush 70 is detachably mounted on one end of the brush head shaft 20 away from the reciprocating mechanism 50 , so as to facilitate replacement of the cleaning brush 70 after it is worn.
[0051] It can be seen from the above technical solution that by arranging a sliding part 51, a driving worm 52 and a worm connecting seat 53 in the shell 10, the driving worm 52 drives the cleaning brush 70 connected to the sliding part 51 to reciprocate under the drive of the driving motor 30, so that the stains on the surface of the object can be scraped back and forth and cleaned; it can conveniently and efficiently clean uneven surfaces, corners or narrow areas, and has the effects of strong ability to clean stubborn stains, easy control of cleaning direction and less wear on the surface of the object.
