Description

Title of the invention: Spin broom

Technical Field The present invention relates to the technical field of cleaning tools, and more particularly a spin broom.

PRIOR ART [0002] Patent document W02015 / 010577A1 describes a mop with rotary spin, which comprises a mop rod mechanism, the mop rod mechanism comprising an upper tube and a lower tube which are locked by an element of locking. A stopper portion is formed at the first end of the locking member and a pulling portion is formed at the second end of the locking member. To use it, a user must hold the mop rod with one hand and operate the trigger with the other hand to lock or unlock. The aforementioned operation has drawbacks such as complex set-up and a poor user experience.

Patent document CN103417168A also describes a rotary spin brush, which includes a spin mechanism which is sleeved outside the lower tube and which can move up and down along the lower tube. The wringing mechanism further includes a locking sleeve, a splash guard and a water outlet cover. The water outlet cover is sheathed outside the bottom tube and the locking sleeve is placed outside the water outlet cover. A locking mechanism is arranged on the water outlet cover and the locking sleeve. The locking mechanism can interact with the lower tube. When the mop head needs to be spun, the spin mechanism can be pushed down. Due to the through grooves arranged in the locking sleeve, deformations can be generated at the upper end of the locking sleeve. When the concave grooves slide out of the convex ribs which are arranged at the lower end of a protective sleeve, the wringing mechanism can slide down along the lower tube to where the mop head fully penetrates the inner chamber of the water outlet cover. Once the mop head has been wrung out, the wringing mechanism can be pulled up. As a result, the concave grooves in the locking sleeve and the convex ribs on the periphery of the lower end of the protective sleeve are engaged. At this point, the wringing mechanism is suspended from the lower end of the protective sleeve and the broom is ready to use. Although the elastic deformation generated at the upper end of the locking sleeve allows the concave grooves of the locking sleeve to slide outward or be engaged with the convex ribs, the operating process is extremely laborious. Even worse, the aforementioned locking mechanism can be worn out after prolonged use, which is inconvenient for later uses.

The rotary brush rod 10 comprises an upper tube 1, a lower tube 2 and a rotary drive mechanism. The upper tube 1 and the lower tube 2 are movably connected by the rotary drive mechanism. The upper tube 1 and the lower tube 2 can move up and down relative to each other and can rotate relative to each other. The lower tube 2 is connected to the connection piece of the cleaning body 9. The mechanism for rotating the rotary brush 10 of this embodiment has been described in patent CN203447246U.

In this embodiment, the cleaning body 3 is connected to the lower tube 2. The outer cover 5 is sleeved outside the lower tube 2 and can go up and down along the lower tube 2. During the process the cleaning body 3 is partially or entirely located in the outer cover 5. The upper tube 1 and the lower tube 2 move up and down so that the cleaning body 3 can be dried by wringing 'through the rotary drive mechanism. During the cleaning state, the lower tube 2 can be pushed down, thus allowing the cleaning body 3 to be located outside the external cover 5. In this embodiment, the fixing sleeve 4 is fixedly connected to the upper tube 1.

This embodiment further comprises a locking mechanism for locking the rotary brush rod 10. The locking mechanism comprises a first limiting mechanism limiting the lower tube 2 and the outer cover 5 in the circumferential direction, a second limiting mechanism limiting the upper tube 4 and the outer cover 5 in the circumferential direction, and an engagement mechanism disposed between the fixing sleeve 4 and the outer cover 5, the rotary brush rod is locked when the outer cover 5 and the fixing sleeve 4 are engaged by the engagement mechanism. The lower tube 2 and the outer cover 5 are limited in the circumferential direction, and the upper tube 1 and the outer cover 5 are limited in the circumferential direction. Because the fixing sleeve 4 is fixedly connected to the upper tube 1, the upper tube 1 and the lower tube 2 are also relatively fixed when the outer cover 5 has meshed with the fixing sleeve 4.

Preferably, the first limiting mechanism of the embodiment comprises a tooth crown 11 disposed on the lower tube 2, an inner tooth 52 disposed on the outer cover 5. The tooth crown 11 is fixedly connected to the lower tube 2. When the outer cover 5 and the fixing sleeve 4 are engaged by the engagement mechanism, the internal tooth 52 has meshed with the sleeve 11. Preferably, the end of the internal tooth 52 becomes progressively more fine relative to the main body part, and the internal tooth 52 and the tooth crown 11 are more gently engaged.

Preferably, the second limiting mechanism comprises a tooth groove 41 which is arranged on the fixing sleeve 4 and an external tooth 51 which is arranged on the external cover 5. When the external cover 5 and the fixing sleeve 4 are engaged by the engagement mechanism, the external tooth 51 has meshed with the tooth groove 4L Preferably, the end part of external tooth 51 becomes progressively thinner relative to the main body part so that the external tooth 51 and the fixing sleeve 4 are more gently engaged.

Preferably, the first limiting mechanism of the embodiment comprises a tooth crown 11 disposed on the lower tube 2, and an internal tooth 52 disposed on the outer cover 5. The tooth crown 11 is fixedly connected to the lower tube 2, and the second limiting mechanism comprises a tooth groove 41 disposed on the fixing sleeve 4, and an external tooth 51 disposed on the external cover 5; the external tooth 51 has meshed with the tooth groove 41, and the internal tooth 52 has meshed with the tooth crown 11 when the external cover 5 and the fixing sleeve 4 are engaged by the engagement mechanism.

In the embodiment, the gears are in concave-convex adjustment instead of being closely engaged. In practice, there may be a gap between components due to cost and assembly errors.

The engagement mechanism of this embodiment comprises a concave position 40 which is arranged on the inner wall of the fixing sleeve 4 and a hook 53 which is arranged on the outer cover 5. When the outer cover 5 and the fixing sleeve 4 are engaged by the engagement mechanism, the jumper hook 53 is expanded in the concave position 40, thus achieving expanded engagement between the outer cover 5 and the fixing sleeve 4.

In this embodiment, the concave position 40 is arranged under the fixing sleeve 4 and the jumping hook 53 is arranged under the external tooth 51. When the external cover 5 approaches the fixing sleeve 4, the mechanism limitation first locks the upper tube 1 and the lower tube 2, then locks further.

As shown in Figures 4 to 7, in order to achieve a labor saving operation, the present invention provides a loop mechanism 7 between the outer cover 5 and the cleaning body connection piece 9 for engaging or release the external cover 5 and the connection piece from the cleaning body 9. The loop mechanism 7 comprises a sliding sleeve 71, a coupling 72 and a drive mechanism for pushing the sliding sleeve 71 to slide axially along the rod rotary broom. A mounting portion used to mount the hitch 72 is disposed on the side wall of the outer cover 5. The mounting portion includes a through hole 81 and a hanger rod 82. A protruding rod 721 corresponding to the hanger rod 82 is arranged at one end of the coupling 72. A part constituting a stage or a concave part which can be hooked firmly by the coupling 72 is arranged. The coupling 72 can move towards the connection piece of the cleaning body 9 through the sliding sleeve 71 so that the connection piece of the cleaning body 9 can be hooked stably by the coupling 72. The other end of the coupling 72 is a hook part. The hook part comprises a hook heel part 7221 and a hook end part 7222. A vertical being produced at the level of the projecting rod 721, said heel part of the hook 7221 and the end part of the hook 7222 are respectively located on the two sides of the vertical. The sliding sleeve 71 abuts against the coupling 72 and the plumb bob is inclined when the external cover 5 has meshed with the connection piece of the cleaning body 9. When the external cover 5 and the connection piece of the cleaning body cleaning 9 are released, the sliding sleeve 71 no longer bears against the hitch 72, thus allowing the hitch 72 to pivot under the effect of gravity. Thus, the plumb bob returns in the vertical direction and the hook end part 7222 is distant from the connection piece of the cleaning body 9.

In this embodiment, the two ends of the sliding sleeve 71 are respectively provided with an opening, and the sliding sleeve 71 is sleeved on the rotary brush rod. When mounting the coupling 72, the projecting rod 721 and the suspension rod 82 are suspended from top to bottom. When the sliding sleeve 71 abuts against the hook heel part 7221, the coupling 72 penetrates through the through hole 81, and the coupling 72 is hooked to the connection piece of the cleaning body 9. When the sliding sleeve 71 moves upwards, the coupling 72 is separated from the connection piece of the cleaning body 9.

In addition, the present invention further comprises locking edges 723 limiting the coupling 72. The coupling 72 is disposed between the two locking edges 723 and the two locking edges 723 serve to limit the coupling 72 in order to avoid shifting or misalignment when the hooking or unhooking state is switched, which prevents the coupling 72 from changing state smoothly.

The hook end part 7222 of the present invention is provided with a chamfer. The end part of the hook 7222 is provided with a chamfer which is more flexible for locking by compression or for releasing the hook and the connection piece from the cleaning body 9.

The drive mechanism of the present invention comprises a button 731, a spring 732, a pressure spring 733 and an inclined surface 734 which is arranged on the side wall of the sliding sleeve 71. The spring 732 is sleeved at the exterior of the rotary brush rod, and imposes a force on the sliding sleeve 71, allowing the sliding sleeve 71 to move downward to come into abutment against the hook heel part 7221. Thus, the coupling 72 penetrates through the through hole 81 so that the connection piece of the cleaning body 9 can be hooked by the coupling 72. The button 731 is provided with a force-receiving surface which can resist the sliding sleeve 71 to move it away from the force-receiving surface of the hook heel part 7221. The pressure spring imposes a force on the button 731, and the force-receiving surface is gradually in contact with the inclined surface of the pa lateral king of the sliding sleeve 71. Consequently, the sliding sleeve 71 moves away from the hook heel part 7221, and the pressure spring 733 is reset with the button 731.

In this embodiment, the cleaning body 3 comprises a base, a side plate and a broom cloth, in which the base is rotatably connected to the side plate, the two ends of the cloth are so connected fixed to the side plate, and the cleaning body 3 can be deformed. During cleaning, the cleaning body 3 can be enlarged to improve the cleaning efficiency. During spinning, the cleaning body 3 can be reduced to obtain a practical self-cleaning.

The present embodiment is another embodiment of the cleaning body 3, which comprises a flexible plate and a broom cloth. The broom cloth is fixedly connected to the flexible plate, and the cleaning body can be deformed.

In this embodiment, the cleaning body 3 can also be in a conventional manner, which comprises a cleaning plate, a broom cloth, and which is deformed by the very nature of the broom cloth.

The present invention has been described in the above embodiments, but in no way intended to limit the scope of the present invention, and all modifications and improvements made by those skilled in the art without departing from the The spirit and scope of the present invention must be within the scope of the protection of the present invention.
