Technical Field

The utility model relates to the technical field of daily life cleaning, in particular to a telescopic gap brush.

Background

The difficulty in cleaning narrow gaps such as window sill and narrow spaces such as indoor corners is generally great, and cleaning tools with certain deformability such as brushes are required.

However, the conventional size of the brush is difficult to clean by entering into a gap such as a window sill due to a small space to be cleaned, and the cleaned garbage is difficult to collect and transport due to the small space to be cleaned.

Disclosure of utility model

In order to solve at least one of the problems of difficulty in cleaning a narrow space, difficulty in collecting and transferring cleaned garbage, etc. by using a conventional size brush, according to an aspect of the present utility model, there is provided a telescopic slit brush.

Therefore, when the brush body is required to be used, the brush body can be driven to move along the direction parallel to the first direction through the first moving mechanism so as to move out of the first opening, and the brush body can be used; when the brush body is cleaned, the dust hopper can be detached from the shell, and cleaned garbage is swept into the dust hopper through the brush body so as to collect and transport the garbage; when the brush body is not required to be used, the brush body can be driven to move reversely through the first moving mechanism, so that the brush body is retracted into the first accommodating cavity from the first opening, and the structural compactness of the telescopic gap brush in a non-use state is guaranteed.

In some embodiments, the telescopic slit brush further includes an operating portion fixedly disposed with respect to the first moving mechanism, the operating portion being located outside the first accommodating chamber. Therefore, when a user grasps the shell, the first moving mechanism can be operated by the operating part to drive the brush body to move.

In some embodiments, the first moving mechanism comprises at least one of a first slider and a first chute, the first slider and/or the first chute are provided on the brush body, and the first chute is provided along a first direction; and a second sliding groove which is arranged on the shell and is matched with the first sliding groove and/or a second sliding groove which is matched with the first sliding groove, wherein the second sliding groove is arranged along the first direction. Thereby, the direction in which the brush moves relative to the housing can be defined by the first movement mechanism. Preferably, the axis of the first slider is not coaxial with the axis of the second slider, so as to avoid rotation of the brush body relative to the housing under the limitation of the first moving mechanism.

In some embodiments, the brush body comprises a first plate and a second plate which can generate elastic deformation, the first plate is provided with a first mounting hole matched with the first sliding block, and the first sliding groove is arranged on the second plate; the operating part and the first sliding block are relatively and fixedly arranged, and the diameter of the operating part and the width of the first plate are both larger than the groove width of the second sliding groove.

In some embodiments, the telescopic slit brush further comprises a second opening provided on the housing to communicate the first accommodation chamber with the outside, and a first mount detachably connected to the housing to block the second opening; and/or the shell comprises a shell body and a second mounting seat, the first accommodating cavity is formed in the shell body, a third opening for communicating the first accommodating cavity with the outside is further formed in the shell body, the second mounting seat is detachably formed in the shell body, and the first opening is formed in the second mounting seat, so that the third opening communicates the first accommodating cavity with the outside through the first opening.

Therefore, the second opening or the third opening can be exposed in a mode of disassembling the first mounting seat from the shell or disassembling the second mounting seat from the shell body, so that an operator can conveniently assemble and disassemble the brush body through the second opening and the third opening.

In some embodiments, the housing is further provided with a fourth opening communicating the first accommodation chamber with the outside; the dust hopper is detachably connected with the shell through the mode of being clamped with the fourth opening, and can extend into the first accommodating cavity when being detachably connected with the shell, and the fourth opening is plugged. Therefore, the compactness of the whole structure of the telescopic gap brush can be ensured when the dust hopper is not used while the convenience in disassembling the dust hopper is ensured.

In some embodiments, the telescopic slit brush further comprises a limiting block fixedly arranged relative to the housing and used for limiting the dust hopper to swing up, down, left and right relative to the housing. Thereby, the stability of the dust hopper mounted on the housing can be ensured.

In some embodiments, the dust hopper has a handle that protrudes outwardly relative to the housing when the fourth opening is in the plugged condition. Thereby, the dust hopper can be taken out of the shell by gripping the handle when the dust hopper is mounted on the shell.

In some embodiments, the telescopic slit brush further comprises first concave portions arranged on two opposite sides of the shell, and the extending direction of the first concave portions is perpendicular to the first direction. Thus, when the user uses the telescopic slit brush, the user can grasp the shell more stably by placing the fingers into the first concave parts.

In some embodiments, the first recess is circular in cross-section and increases in cross-section from its bottom to its top. Therefore, convenience and comfort of grasping by a user can be ensured while convenience of processing of the first concave part is ensured.
