Description

Technical Field

[0001] The utility model relates to the field of daily necessities, in particular to a bathroom brush. Background Art

[0002] A bathroom brush is a brush used to clean the bathroom. The brush head and the brush rod of a traditional bathroom brush are mostly integrated. As the brush head is worn out over time, the entire brush can only be discarded together, so it has the disadvantage of being not economical. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a bathroom brush.

[0004] The bathroom brush comprises a brush head and a brush rod, the upper surface of the brush head is provided with a C-shaped connection groove, the upper surface of the brush head is provided with a retaining edge extending inwardly along the contour of the connection groove, the brush rod is provided with a connecting plate matching the connection groove, the front and both sides of the connecting plate are provided with step layers, the connecting plate can be inserted into the connecting groove from the opening of the connecting groove and the step layer of the connecting plate is clamped under the retaining edge of the connecting groove, the retaining edge prevents the connecting plate from detaching from the top, the front, left and right connection grooves are provided to prevent the connecting plate from detaching from the front, left and right directions, and the rear of the connecting plate is provided with an elastic clamping plate, and the clamping plate is provided with a clamping A coupling hole, after the connecting plate is inserted into the connecting groove to the bottom, a protrusion is provided at a position on the upper surface of the brush head corresponding to the engaging hole, and the protrusion is engaged in the engaging hole to limit the rear direction of the connecting plate, thereby preventing the connecting plate from detaching from the rear direction; the advantage of the utility model is that the brush head and the brush rod can be separated by moving the engaging plate so that the protrusion can relatively leave the engaging hole, and then the connecting plate of the brush rod can be pulled out of the connecting groove on the brush head, so that the brush head can be replaced, and the design is relatively more firm when the brush head and the brush rod are connected, and replacement is more convenient.

[0005] Furthermore, one side of the brush head is triangular, and bristles are provided on the triangular side. The advantage of this design is that the bristles on the side can clean some gaps, and the triangular design makes the bristles at the front relatively protruding, which can clean more carefully.

[0006] Furthermore, considering some usage environments, such as cleaning walls, in order to facilitate cleaning, the brush rod of the utility model is provided with a bending structure so that the brush rod can be bent at a certain angle, such as 90 degrees. In this case, the brush rod can be held by hand so that the bristles at the bottom of the brush head face the wall.

[0007] Furthermore, in conjunction with the bending structure, the brush rod is divided into at least two sections, the bending structure includes a support plate arranged on one of the brush rods, and a first support sleeve and a second support sleeve arranged on the other brush rod, the first support sleeve and the second support sleeve are arranged at intervals and are established on both sides of the support plate, the bending structure also includes a fixed shaft interlaced with the first support sleeve, the second support sleeve and the support plate, the fixed shaft is movably arranged along the axial direction, and at least one convex rib is provided on its outer periphery, and a transmission groove cooperating with the convex rib is provided on the first support sleeve, and the circumferential fixation of the fixed shaft and the first support sleeve can be achieved through the cooperation of the transmission groove and the convex rib, a circle of locking groove is provided on the side of the support plate opposite to the convex rib, and the fixed The fixed shaft can selectively make its outer circumferential ridges engage or not engage with the locking grooves on the support plate through axial movement, thereby realizing circumferential fixation or non-fixation of the fixed shaft and the support plate; the principle of this design is to control the bending of the brush rod by the fixed shaft. Specifically, the fixed shaft always remains circumferentially fixed to the first support sleeve, which means that it is always circumferentially fixed to one section of the brush rod, and the circumferential fixation of the fixed shaft and the support plate is adjustable. When the outer circumferential ridges of the fixed shaft engage with the locking grooves on the support plate, the circumferential fixation of the fixed shaft and the other section of the brush rod is realized, and then the angle of the two sections of the brush rod is fixed. When the outer circumferential ridges of the fixed shaft do not engage with the locking grooves on the support plate, the angle between the two sections of the brush rod can be rotated to adjust.

[0008] Furthermore, the fixed shaft is provided with an integrally arranged first end cover at the end portion on one side of the first support sleeve, and the function of the first end cover is to cover the internal structure and improve the appearance.

[0009] Furthermore, the fixed shaft is provided with a second end cover at the end on one side of the second supporting sleeve, and the second end cover is provided with two elastic locking buckles. The interior of the fixed shaft is hollow and a locking buckle hole cooperating with the elastic locking buckle is provided on the fixed shaft. The second end cover is inserted into the fixed shaft by means of the elastic locking buckle and hooked on the locking buckle hole to be fixed to the fixed shaft; the function of the second end cover is to fix the fixed shaft so that it will not separate from the first supporting sleeve, the second supporting sleeve and the supporting plate.

[0010] Furthermore, a spring is provided between the second end cover and the second support sleeve. The function of the spring is to facilitate the angle adjustment of the brush rod. Specifically, under normal conditions, the fixed shaft is biased toward one side of the second support sleeve, and the convex ridges on the outer periphery of the fixed shaft engage with the locking slots on the support plate, and the angles of the two sections of the brush rod are fixed. When adjusting the angle, the second end cover is pressed, the spring is compressed, and the second end cover also drives the fixed shaft to move in the direction of the first support sleeve, thereby disengaging the convex ridges on the outer periphery of the fixed shaft from the locking slots on the support plate. The two sections of the brush rod can be rotated to adjust the angle. After adjustment, the fixed shaft is restored under the action of the spring reset, and the angles of the two sections of the brush rod are fixed. The advantage of this design is that it is very convenient to adjust and fix, and only the second end cover needs to be pressed.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model provides a bathroom brush, wherein the brush head and the brush rod can be connected by moving the clamping plate so that the protrusions can relatively leave the clamping holes, and then the connecting plate of the brush rod can be pulled out of the connecting groove on the brush head, so that the brush head can be replaced. The design is relatively more firm when the brush head and the brush rod are connected, and replacement is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
