Description

Technical Field

[0001] This utility model relates to the field of tile cleaning technology, specifically to a portable cleaning brush for tiles. Background Technology

[0002] Tiles are a widely used building material, commonly used for decorating floors and walls. They are favored for their durability, ease of cleaning, and aesthetic appearance. After tiles are laid, it is necessary to use a cleaning brush to clean the dirt in the grout lines to facilitate later tile grout sealing.

[0003] Currently, the brush heads of existing tile cleaning brushes on the market cannot be hidden and stored after use. As a result, the brush heads are exposed to the outside for a long time and are subject to external contact, which can cause the bristles to loosen at the base and fall out. Utility Model Content

[0004] The purpose of this invention is to provide a portable cleaning brush for ceramic tiles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This portable cleaning brush for tiles, when stored, is held with the left hand holding the handle and the right hand pulling the lever. The lever, through a connector, retracts the brush head into the lower part of the housing. When the slider moves to the upper end of the side groove and can no longer move, the lever is rotated. The lever drives the protrusions on both sides of the rotating head to rotate, and the protrusions squeeze the spring rod, causing the positioning block at the other end of the spring rod to insert into the positioning groove and lock. In this way, the brush head will not pop out after being retracted into the housing, thus protecting the brush head and improving its service life.

[0017] 2. This portable cleaning brush for tiles can be used with the brush head wet when cleaning the tile surface. If it is necessary to clean the sewage absorbed inside the brush head, the brush head is pulled into the lower part of the housing and is stretched open by two elastic clamps. A spring is provided between the elastic clamps and the housing. The elasticity of the spring can control the elastic clamps to clamp the brush head in the opposite direction, thereby squeezing the sewage absorbed in the brush head out from the bottom of the housing. After pulling back and forth several times, the sewage can be effectively cleaned. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A portable cleaning brush for tiles includes a housing 1, a connector 2 movably mounted in the middle of the inner side of the housing 1, a brush head 3 at the bottom of the connector 2, a clamping mechanism in the lower inner side of the housing 1 including an elastic clamping plate 5, elastic clamping plates 5 on both sides of the lower inner side of the housing 1, a spring plate 6 on the outer side of the upper end of the housing 1 near the elastic clamping plate 5, the elastic clamping plate 5 being movably connected to the inner wall of the housing 1 through the spring plate 6, a threaded head 7 at the middle of the top of the brush head 3, the brush head 3 being threadedly connected to the bottom end of the connector 2 through the threaded head 7, a helical spring 8 between the connector 2 and the housing 1 outside the pull rod 4, a handle 9 fixedly sleeved on the upper outer side of the housing 1, an anti-slip sleeve 10 on the outer wall of the middle part of the handle 9, side grooves 11 at both ends of the middle inner side of the housing 1, and sliders 12 matching the side grooves 11 on both sides of the upper end of the connector 2.

[0026] In this embodiment, when cleaning the surface of the tile, the brush head 3 can also be wetted. If it is necessary to clean the sewage absorbed inside the brush head 3, the brush head 3 is pulled into the lower part of the housing 1 and the two elastic clamps 5 are spread apart. A spring plate 6 is provided between the elastic clamps 5 and the housing 1. The elasticity of the spring plate 6 can control the elastic clamps 5 to clamp the brush head 3 in the opposite direction, thereby squeezing the sewage absorbed in the brush head 3 out from the bottom of the housing 1. After pulling back and forth several times, the sewage can be effectively cleaned.

[0027] like Figure 2 and Figure 4 As shown, a pull rod 4 is fixedly connected to the upper end of the connector 2. A positioning mechanism is provided between the pull rod 4 and the connector 2. The positioning mechanism includes a rotating head 13. The rotating head 13 is provided at the bottom end of the pull rod 4 and at the upper end of the connector 2. Protrusions 17 are symmetrically provided at both ends of the rotating head 13. Spring rods 14 are provided on both sides of the connector 2 near the rotating head 13. A positioning block 15 is provided at the other end of the spring rod 14. A positioning groove 16 matching the positioning block 15 is opened on the upper inner wall of the housing 1 near the side groove 11.

[0028] In this embodiment, when storing the brush head, hold the handle 9 with your left hand and pull the lever 4 with your right hand. The lever 4, through the connector 2, retracts the brush head 3 into the lower part of the housing 1. When the slider 12 moves to the upper end of the side groove 11 and can no longer move, rotate the lever 4. The lever 4 drives the protrusions 17 on both sides of the rotating head 13 to rotate. The protrusions 17 squeeze the spring rod 14, causing the positioning block 15 at the other end of the spring rod 14 to insert into the positioning groove 16 and lock. In this way, the brush head 3 will not pop out after being retracted into the housing 1, thus protecting the brush head 3 and improving its service life.

[0029] Working principle: During use, the brush head 3 protrudes from the lower exterior of the housing 1. Holding the handle 9, the brush head 3 can be used to clean dust and dirt from tile grout. After use, hold the handle 9 with your left hand and pull the lever 4 with your right hand. The lever 4, through the connector 2, retracts the brush head 3 into the lower interior of the housing 1. When the slider 12 moves to the upper end of the side groove 11 and cannot move further, rotate the lever 4. The lever 4 drives the protrusions 17 on both sides of the rotating head 13 to rotate. The protrusions 17 compress the spring rod 14, causing the positioning block 15 at the other end of the spring rod 14 to insert into the positioning groove 16 and lock in place. Once the brush head 3 is retracted into the housing 1, it will not pop out, thus protecting the brush head 3 and extending its service life. When cleaning tile surfaces, the brush head 3 can also be wetted before use. If it is necessary to clean the sewage absorbed inside the brush head 3, pull the brush head 3 into the lower part of the housing 1, where it will be spread apart by two elastic clamps 5. A spring plate 6 is provided between the elastic clamps 5 and the housing 1. The elasticity of the spring plate 6 can control the elastic clamps 5 to clamp the brush head 3 in the opposite direction, thereby squeezing the sewage absorbed in the brush head 3 out from the bottom of the housing 1. After pulling back and forth several times, the sewage can be effectively cleaned.
