The invention relates to a handheld scrubbing mechanism for a building ceiling. For example, the handheld scrubbing mechanism for the ceiling of the building comprises a holding assembly, a covering assembly and a scrubbing assembly, wherein the holding assembly comprises a holding rod, an elastic piece and a pushing ring seat. For example, the elastic member is sleeved on the holding rod, the pushing ring seat is connected to one end of the elastic member and slidably sleeved on the end of the holding rod, and the covering assembly comprises a ring member and a bowl-shaped elastic cover. For example, the ring member is slidably fitted over the holding rod and fixed to a middle portion of the elastic member. For example, the bowl-shaped elastic cover is connected to the ring-shaped piece, and is used for covering the scrubbing assembly, and the scrubbing assembly comprises a plurality of scrubbing strips which are rotatably arranged at the end part of the holding rod. For example, the plurality of scrubbing strips extend outward in the radial direction of the holding rod, and one side of the scrubbing strips is provided with a scrubbing belt. For example, the push ring seat can move under the action of the elastic piece to push the plurality of scrubbing strips to contract and gather.

Referring to fig. 1 to 3, a hand-held scrubbing mechanism for a building ceiling includes a holding assembly 10, a covering assembly 20 and a scrubbing assembly 30, where the holding assembly 10 includes a holding rod 11, an elastic member 12 and a push ring seat 13, the elastic member 12 is sleeved on the holding rod 11, the push ring seat 13 is connected to one end of the elastic member 12 and slidably sleeved on an end portion of the holding rod 11, the covering assembly 20 includes a ring member 21 and a bowl-shaped elastic cover 22, the ring member 21 is slidably sleeved on the holding rod 11 and fixed on a middle portion of the elastic member 12, the bowl-shaped elastic cover 22 is connected to the ring member 21, the bowl-shaped elastic cover 22 is used for covering the scrubbing assembly 30, the scrubbing assembly 30 includes a plurality of scrubbing strips 35, the scrubbing strips 35 are rotatably disposed on an end portion of the holding rod 11, the scrubbing strips 35 extend outwards along the radial direction of the holding rod 11, a scrubbing belt 351 is arranged on one side of each scrubbing strip 35, and the pushing ring seat 13 can move under the action of the elastic piece 12 to push the scrubbing strips 35 to contract and gather together.

When the hand-held scrubbing mechanism for the building ceiling is used, a user holds the end part of the holding rod 11, the scrubbing strips 35 are abutted to the ceiling, then the holding rod 11 is rotated to drive the scrubbing assembly 30 to rotate, then the scrubbing belts 351 on the scrubbing strips 35 are utilized to scrub the ceiling, oil, water, dust and the like on the ceiling can be shielded and collected through the bowl-shaped elastic cover 22 and the like, the ceiling is prevented from falling into the head or eyes of the user, and therefore the scrubbing of the ceiling by the hand-held scrubbing mechanism for the building ceiling is facilitated.

For example, the outer diameter of the bowl-shaped elastomeric cover 22 is greater than twice the length of the scrubbing strip 35 for the user to view scrubbing. The bowl-shaped elastic cover 22 is made of a transparent material. The middle part of the holding rod 11 is convexly provided with a baffle ring 115, and the baffle ring 115 and the pushing ring seat 13 are arranged at intervals. The elastic member 12 is a spring, and one end of the spring, which is far away from the push ring seat 13, is connected to the baffle ring 115. The top edge of the bowl-shaped elastic cover 22 is lower in height than the scrubbing strips 351 of the scrubbing strip 35. Through setting up the height at the top edge of bowl shape elastic cover 22 is lower, and then makes a plurality of strips 35 of scrubbing can make the dust at its edge fall into all the time when removing and scrubbing in the bowl shape elastic cover 22, promptly the bowl shape elastic cover 22 can not touch the ceiling and lead to the profit dust to follow the edge of bowl shape elastic cover 22 falls down.

For example, in order to facilitate gathering the scrubbing strips 35, the end surface of the push ring seat 13 is provided with a plurality of push grooves 131, and the push grooves 131 are uniformly spaced along the circumference of the end surface of the push ring seat 13. Each of the pushing grooves 131 penetrates through the sidewall of the pushing ring seat 13 along the radial direction of the pushing ring seat 13, and a retaining groove 133 is concavely disposed on one side of each of the pushing grooves 131. The scrubbing strip 35 is arranged in the retaining groove 133 in a penetrating manner, and an elastic deformation layer is formed on the end face of the pushing and holding ring seat 13.

When the plurality of scrubbing strips 35 move into the plurality of pushing grooves 131 relative to the pushing ring seat 13 by exerting force upwards to make the elastic deformation layer support the ceiling and then reversely rotating the holding rod 11, the elastic member 12 can force the pushing ring seat 13 to move radially relative to the holding rod 11 so as to press and gather the plurality of scrubbing strips 35 and squeeze out moisture on the plurality of scrubbing strips 35.

For example, it is particularly important that the ends of the scrubbing strips 35 are formed with hard cleaning blocks 355, the hard cleaning blocks 355 protrude toward the side away from the scrubbing belt 351, the hard cleaning blocks 355 are used for gathering together to form a hard friction part under the driving of the scrubbing strips 35, and the hard cleaning blocks 355 are used for stopping the push ring seat 13 from popping out of the ends of the scrubbing strips 35. The elastic member 12 is further configured to stretch and drive the bowl-shaped elastic cover to move when pushing the plurality of scrubbing strips 35 to gather together, so that the bowl-shaped elastic cover moves backward relative to the push ring base 13 to expose the hard friction portion. Since the ring member 21 is fixed to the middle of the elastic member 12, the elastic member 12 is stretched by a length twice, and the bowl-shaped elastic cover 22 moves by a length 0.5 times, so that the bowl-shaped elastic cover 22 moves backward relative to the push ring base 13. At this time, the user can see the hard friction portion more clearly and hold the ceiling by rotating the hard friction portion, which is also used for the rotational friction to remove the solidified stain or hard matter on the ceiling. The plurality of axial slots also serve to receive and guide the plurality of scrubbing strips 35 due to the limitations of the plurality of axial slots.

For example, in order to facilitate the scrubbing strips 35 to be turned over again for the next cleaning or to continue cleaning the ceiling, please refer to fig. 4 and 5, for example, in order to facilitate spraying the cleaning solution, an annular thickened ring portion 225 is formed in the middle of the bowl-shaped elastic cover 22, an annular channel is provided in the thickened ring portion 225, a plurality of inclined ejection holes 2255 are provided on the thickened ring portion 225, the inclined ejection holes 2255 are all communicated with the annular channel, an elastic connection pipe is provided on the bowl-shaped elastic cover 22, one end of the elastic connection pipe is connected to the bowl-shaped elastic cover 22, and the other end of the elastic connection pipe extends to the holding rod 11 and is connected to a cleaning solution ejection pump.
