[0006] Preferably, the limiting structure includes a sliding sleeve and a convex ring, the connecting sleeve is slidably connected to the sliding sleeve, one end of the sliding sleeve is fixedly connected to two plug shafts, one end of the brush head is provided with two slots, and the plug shafts are engaged with adjacent slots.
[0007] Preferably, a connecting block is fixedly connected to the outer side of the connecting sleeve, and a return spring is provided on the outer side of the connecting sleeve. One end of the return spring abuts against the sliding sleeve, and the other end of the return spring abuts against the connecting block.
[0008] Preferably, a plurality of convex rings are fixedly connected to the outer side of the sliding sleeve, and the plurality of convex rings are linearly and equidistantly distributed.
[0009] Preferably, the two plug-in shafts are symmetrically distributed about the center of the sliding sleeve, and the cross-section of the top end of the plug-in shaft is a trapezoidal structure.
[0010] Preferably, a sealing gasket is engaged on the connecting sleeve, and the sealing gasket is in contact with the brush head.
[0011] Preferably, a handle is engaged at one end of the brush rod, and a fixing sleeve is engaged on the handle. A groove is provided on the brush rod, and the fixing sleeve is engaged with the groove.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8 As shown, a detachable cleaning brush includes a brush rod 1, one end of the brush rod 1 is fixedly connected to a connecting sleeve 2, one side of the connecting sleeve 2 is in contact with a brush head 3, the end of the brush head 3 is fixedly connected to a connecting block 4, the end of the connecting sleeve 2 is provided with a bayonet 5, the connecting block 4 is engaged with the bayonet 5, and a limiting structure 6 is provided on the connecting sleeve 2.
[0026] As a technical optimization solution of the utility model, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the limiting structure 6 includes a sliding sleeve 601 and a convex ring 602. The sliding sleeve 601 is slidably connected to the connecting sleeve 2. One end of the sliding sleeve 601 is fixedly connected to two plug shafts 603. One end of the brush head 3 is provided with two slots 604. The plug shafts 603 are engaged with adjacent slots 604, so as to prevent the brush head 3 from falling off from the connecting sleeve 2 during use, thereby effectively improving the stability of use.
[0027] As a technical optimization solution of the utility model, Figure 4 As shown, the outer side of the connecting sleeve 2 is fixedly connected with a connecting block 605, and the outer side of the connecting sleeve 2 is provided with a reset spring 606. One end of the reset spring 606 abuts against the sliding sleeve 601, and the other end of the reset spring 606 abuts against the connecting block 605. Therefore, under the action of the reset spring 606, the plug shaft 603 can always be engaged with the slot 604.
[0028] As a technical optimization solution of the utility model, Figure 1 and Figure 4 As shown, a plurality of convex rings 602 are fixedly connected to the outer side of the sliding sleeve 601 , and the plurality of convex rings 602 are linearly and equidistantly distributed, thereby preventing the hand from slipping when pushing the sliding sleeve 601 .
[0029] As a technical optimization solution of the utility model, Figure 4 As shown in the figure, the two plug shafts 603 are symmetrically distributed about the center of the sliding sleeve 601, and the cross-section of the top of the plug shaft 603 is a trapezoidal structure, so it can play a guiding role when the plug shaft 603 is engaged with the slot 604.
[0030] As a technical optimization solution of the utility model, Figure 4 and Figure 8 As shown, a sealing gasket 12 is engaged with the connecting sleeve 2 , and the sealing gasket 12 contacts the brush head 3 , thereby improving the sealing performance between the brush head 3 and the connecting sleeve 2 .
[0031] As a technical optimization solution of the utility model, Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, a handle 7 is engaged at one end of the brush rod 1, and a fixing sleeve 10 is engaged on the handle 7. A groove 11 is provided on the brush rod 1, and the fixing sleeve 10 is engaged with the groove 11, so that flexible disassembly and assembly between the brush rod 1 and the handle 7 can be achieved.
[0032] As a technical optimization solution of the utility model, Figure 3 and Figure 5 As shown, the outer cover of the handle 7 is provided with a rubber cover 9 , and the rubber cover 9 is in contact with the fixed cover 10 , so that the rubber cover 9 can improve the comfort of holding.
[0033] As a technical optimization solution of the utility model, Figure 1 As shown, a through hole 8 is provided on the handle 7, and the cross section of one side of the rubber sleeve 9 is a wave-shaped structure, so the through hole 8 can facilitate the hanging of the cleaning brush.
[0034] When the present invention is in use, when the bristles of the cleaning brush are seriously worn and need to be replaced, it is only necessary to push the sliding sleeve 601 to shrink the return spring 606. By providing a plurality of convex rings 602, it is possible to avoid the hand slipping when pushing the sliding sleeve 601. The movement of the sliding sleeve 601 will drive the two plug shafts 603 to move. When the plug shaft 603 and the slot 604 are not engaged, the brush head 3 can be rotated. After the brush head 3 is rotated ninety degrees, the brush head 3 can be moved to remove the connecting block 4 from the inside of the bayonet 5, thereby realizing the rapid disassembly of the brush head 3. After the old brush head 3 is disassembled, the new brush head 3 can be quickly installed on the connecting sleeve 2. Therefore, when the bristles of the cleaning brush are seriously worn, it is only necessary to replace the brush head 3 separately, avoiding the need to replace the entire brush head. The cost of use is effectively saved. By arranging the sealing gasket 12, the sealing between the brush head 3 and the connecting sleeve 2 can be improved, thereby preventing water from entering the interior of the connecting sleeve 2 and the brush rod. By arranging the through hole 8, the cleaning brush can be conveniently hung. By arranging the rubber sleeve 9, it can be more comfortable when holding. Since the cross-section of one side of the rubber sleeve 9 is a wavy structure, the stability when holding can be improved. Since the rubber sleeve 9 is made of elastic material, it can be removed from the handle 7. After the rubber sleeve 9 is removed, it will not resist the fixed sleeve 10, and then the fixed sleeve 10 can be removed. After the fixed sleeve 10 is removed, the brush rod 1 can be pulled out from the inside of the handle 7, thereby realizing flexible assembly of the handle 7 and the brush rod 2, which is more convenient to use.
