Referring to fig. 1 and 2, a floor brush 100 according to an embodiment of the present invention includes a floor brush body 120 and a rolling brush body 130 detachably mounted on the floor brush body 120.

Therefore, the rolling brush body 130 can be detached from the floor brush body 120 to clean the sundries on the rolling brush body 130, and the cleaning efficiency of the floor brush 100 is improved.

Referring to fig. 2 to 4, in the present embodiment, preferably, the rolling brush body 130 includes a first member 131 and a second member 132 connected to each other, and the second member 132 moves relative to the first member 131, so that the rolling brush body 130 and the floor brush body 120 are detachably mounted.

In the present embodiment, the first member 131 is preferably a main body 133 of the roll brush body 130, and the second member 132 is preferably an end cap 134 provided at one end of the main body 133.

The main body 133 of the roll brush body 130 is usually flocked or napped to improve cleaning efficiency, and as shown in fig. 1, the main body 133 is covered with the flocks.

The second member 132 axially moves and circumferentially moves relative to the first member 131, so that the rolling brush body 130 and the floor brush body 120 can be detachably mounted, and the rolling brush body is convenient and quick to use, wherein the axial movement and the circumferential movement can be simultaneously or sequentially performed, that is, the circumferential movement can be simultaneously performed during the axial movement, at this time, the circumferential movement can be either passively performed (as in the structure shown in fig. 5 to 12) or actively performed (as in the manual rotation of a user, the structure can be a simple U-shape), and of course, the circumferential movement can be performed after the axial movement is completed, and no limitation is made here, simultaneously or sequentially.

In the present embodiment, the elastic member 140 is preferably provided between the first member 131 and the second member 132.

During installation, the second member 132 is pressed against the force of the elastic member 140 to move the second member 132 axially and circumferentially relative to the first member 131, the second member 132 is released, and the second member 132 is moved to the installation position by the elastic member 140.

During disassembly, the second member 132 is pressed against the force of the elastic member 140 to move the second member 132 axially and circumferentially relative to the first member 131, the second member 132 is released, and the second member 132 is moved to the disassembly position by the elastic member 140.

The elastic element 140 is used for assisting the relative movement between the second part 132 and the first part 131, and the structure is simple and reasonable. In particular, when the rolling brush body 130 is in the installation position, the elastic member 140 applies a force to the second member 132 away from the first member 131, so that the rolling brush body 130 can be reliably maintained in the installation position, and the floor brush 100 can be used more stably and reliably.

As previously described, the second member 132 moves axially and circumferentially relative to the first member 131. The roll brush body 130 and the floor brush body 120 are detachably coupled.

Specifically, referring to fig. 2, 5 and 6, a guide mechanism is disposed between the second member 132 and the floor brush body 120, the guide mechanism includes a guide member 142 disposed on the second member 132, and a guide groove 144 disposed on the floor brush body 120, the guide groove 144 includes an open port 146, a fixing portion 148 with a closed distal end, and a groove 150 extending between the port 146 and the fixing portion 148, the port 146 and the fixing portion 148 are spaced at a certain distance in the circumferential direction, and the groove 150 extends at a certain distance in the axial direction.

The guide groove 144 may define a movement path of the guide member 142, so that the guide member 142 moves along a desired path, and the second member 132 moves relative to the first member 131 in a desired movement manner to complete the assembly and disassembly of the roller brush body 130.

The open port 146 may facilitate easy removal of the roller brush body 130. When the installation is performed, the guide 142 enters from the open port 146 to start the installation of the rolling brush body 130 to the floor brush body 120; when the rolling brush body 130 is removed from the floor brush body 120, the guide member 142 is moved to the open port 146, and the second member 132 is located at the removal position.

Since the guide 142 moves in the guide groove 144, the fixing place 148 is a part of the guide groove 144, and thus, the fixing place 148 may not be completely closed. The distal end of the fixing portion 148 is closed, which means that the end of the fixing portion 148 in the direction of the second member 132 away from the first member 131 is closed, and the fixing portion 148 closed at the distal end can fix the second member 132 at a position away from the first member 131, so that the rolling brush body 130 is fixed relative to the brush body 120. That is, during installation, the guide 142 abuts the fixing location 148 and the second member 132 is in the installed position.

The ports 146 and the fixing locations 148 are spaced at a distance in the circumferential direction such that the ports 146 and the fixing locations 148 are staggered, thereby preventing the guide member 142 from accidentally sliding out of the ports 146 and ensuring reliable installation of the rolling brush body 130. Ports 146 and fixed locations 148 are circumferentially spaced to provide circumferential displacement of guide 142 as it moves within guide slots 144; the groove 150 extends in the axial direction for a certain distance. Causing axial displacement of guide member 142 as it moves within guide slot 144. Therefore, the guide 142 is displaced in the axial direction and the circumferential direction simultaneously when moving in the guide groove 144, and the second member 132 is displaced in the axial direction and the circumferential direction simultaneously when moving relative to the first member 131, thereby ensuring the reliable attachment and detachment of the brush body 130.

Thus, when the guide member 142 moves from the opened port 146 to the fixing position 148 in the guide groove 144, the roller brush body 130 is located at the mounting position, and the roller brush body 130 is mounted on the floor brush body 120. When the guide member 142 is moved from the fixing position 148 to the opened port 146 in the guide groove 144, the brush roller 130 is in the detaching position and can be detached from the brush body 120.

In this embodiment, the guide groove 144 includes an installation section 152 and a removal section 154 connected in sequence, the guide groove 144 extending from the open port 146 to the fixed position 148 is the installation section 152, and the guide groove 144 extending from the fixed position 148 to the open port 146 is the removal section 154.

In the preferred embodiment, the mounting section 152 and the dismounting section 154 are the same, and are both the open port 146 and the fixed position 148, but the mounting section 152 and the dismounting section 154 are two different paths. The mounting section 152 and the dismounting section 154 are separated by a partition 155.

Thus, the mounting section 152 and the dismounting section 154 can be not only separately designed, but also prevented from being operated by mistake.

Preferably, the mounting section 152 and the dismounting section 154 each include a leading section 156A/156B, a transition section 158A/158B, and an end section 160A/160B connected in series.

That is, the mounting segment 152 includes a mounting leading segment 156A, a mounting transition segment 158A, and a mounting trailing segment 160A connected in series. The disassembly section 154 includes a disassembly guide section 156B, a disassembly transition section 158B, and a disassembly end section 160B, which are connected in series.

In the present embodiment, the elastic member 140 is preferably disposed between the first member 131 and the second member 132, the guide member 142 moves from the guide section 156A/156B to the transition section 158A/158B against the force of the elastic member 140, and the guide member 142 moves from the transition section 158A/158B to the end section 160A/160B under the action of the elastic member 140.

Specifically, during installation, the operator pushes the second member 132 against the force of the elastic member 140, thereby pushing the guide member 142 from the open port 146 into the installation guide section 156A and moving the guide member in the installation guide section 156A, and when the guide member 142 moves from the installation guide section 156A to the installation transition section 158A, the operator knows that the operation is in place, the operator can release the second member 132, the guide member 142 moves from the installation transition section 158A to the installation end section 160A under the action of the elastic member 140, and then moves under the guidance of the installation end section 160A until the guide member abuts against the fixing position 148, and the rolling brush body 130 is installed in place.

During disassembly, the operator pushes the second member 132 against the force of the elastic member 140, thereby pushing the guide member 142 from the fixing position 148 into the disassembly guide section 156B and moving within the disassembly guide section 156B, and when the guide member 142 moves from the disassembly guide section 156B to the disassembly transition section 158B, the operator knows that the operation is in place, the operator releases the second member 132, the guide member 142 moves from the transition section 158B to the disassembly end section 160B under the action of the elastic member 140, and then moves under the guidance of the disassembly end section 160B until the rolling brush body 130 is detached from the floor brush body 120 with the port 146 opened.

In this embodiment, the force applied by the operator and the acting force of the elastic member 140 are combined, and the installation section 152 and the removal section 154 are reasonably designed, so that the roller brush body 130 is very convenient to assemble and disassemble.

Preferably, the guide section 156A/156B includes a first section 171 and a second section 172 that are angularly disposed, the transition section 158A/158B is connected to the second section 172, and the transition section 158A/158B is circumferentially offset from the first section 171.

Thus, when the operator releases the second member 132 and the guide member 142 is moved by the resilient member 140, the transition sections 158A/158B are not directly connected to the first section 171, and the transition sections 158A/158B are circumferentially offset from the first section 171, preventing the guide member 142 from returning from the transition sections 158A/158B to the guide sections 156A/156B, and allowing the guide member 142 to travel only from the transition sections 158A/158B to the end sections 160A/160B, thereby ensuring reliable attachment and detachment of the brush body 130. In addition, the guiding design of the second section 172 enables the operator to press the second member 132 to enable the guiding element 142 to smoothly reach the transition section 158A/158B without additional rotation, which is simple and convenient in operation.

Preferably, the leading sections 156A/156B and the transition sections 158A/158B are of different linear extensions.

When the operator presses the second member 132 and the guide member 142 moves in the guide groove 144, the operator feels that the shape of the guide groove 144 against which the guide member 142 abuts is changed, and at this time, the guide member 142 enters the transition sections 158A/158B having different line shapes, the operator can judge that the operation is in place, the operator can release his hand, and the rolling brush body 130 can be detached and installed under the action of the elastic member 140. Therefore, in the present embodiment, the guide sections 156A/156B and the transition sections 158A/158B having different extension lines are designed to help the operator determine whether the operation is in place.

Preferably, the transition sections 158A/158B have an extension that matches the extension of the cross-section of the guide 142. This allows the guide 142 to conform well to the transition sections 158A/158B, and when the operator senses this engagement, the operator can accurately determine that his or her operation is in place, which is a reasonable design.

In this embodiment, the main body 133 of the guiding element 142 is cylindrical, and the transition sections 158A/158B extend in arc, so that the guiding element 142 can be well attached to the transition sections 158A/158B, and those skilled in the art can appreciate that the cross sections of the guiding element 142 and the transition sections 158A/158B can be designed as required, and all the embodiments that are the same as or similar to the present embodiment are included in the protection scope of the present invention.

In the present embodiment, preferably, the number of the guide members 142 is several, the several guide members 142 are uniformly distributed in the circumferential direction of the second member 132, and the number of the guide grooves 144 is the same as and matches the number of the guide members 142.

Specifically, in the present embodiment, there are three guide members 142, and the end caps 134 of the three guide members 142 are uniformly spaced in the circumferential direction. Correspondingly, the three guide grooves 144 are circumferentially and uniformly distributed at intervals on the floor brush body 120, specifically, on the inner wall of the receiving groove of the floor brush body 120 for receiving the rolling brush body 130. This can make the roller brush body 130 and the floor brush body 120 more uniformly stressed and more reliably mounted.

It will be appreciated by those skilled in the art that the number of the guiding elements 142 and the guiding grooves 144 can be designed as required, and is not limited to the protection scope of the present invention, and all the embodiments similar to or the same as the present embodiment are covered by the protection scope of the present invention.

The installation process of the roll brush body 130 will be more fully described below.

In installation, referring to fig. 7, the angle of the rolling brush body 130 is adjusted to align the three guide members 142 on the end cap 134 of the rolling brush body 130 with the open ports 146 of the three guide grooves 144 on the floor brush body 120.

Referring to fig. 8 to 10, the operator applies a force to the end cap 134 in a direction approaching the main body 133 of the rolling brush body 130 against the force of the elastic member 140, so that the guide member 142 moves along the first section 171 and the second section 172 of the installation guide section 156A in the guide groove 144 in sequence, when the guide member 142 moves to be engaged with the installation transition section 158A, the operator can sense that the operation is in place, the operator releases his hand, the end cap 134 moves away from the main body 133 of the rolling brush body 130 under the action of the elastic member 140, and the guide member 142 moves from the installation transition section 158A to the installation end section 160A and finally to be engaged with the fixing position 148.

At this time, referring to fig. 11, the roll brush body 130 is reliably mounted on the floor brush body 120.

As the guide 142 moves from the open port 146 to the installation transition 158A, the end cap 134 approaches the body and the axial length of the entire roller brush body 130 is reduced; as guide 142 moves from mounting transition 158A to mounting location 148, end cap 134 moves away from the body and the axial length of the entire roller brush body 130 increases. Therefore, the axial length of the roll brush body 130 may be changed during the installation process. Meanwhile, since the open port 146 is spaced apart from the fixing portion 148 in the circumferential direction, the circumferential angle of the roll brush body 130 is also changed during the installation process.

The following describes the disassembling process of the roller brush body 130 more completely.

During disassembly, referring to fig. 10 and 12, an operator applies a force to the end cap 134 in a direction approaching the main body 133 of the rolling brush body 130 against the force of the elastic member 140, so that the guide member 142 moves along the first section 171 and the second section 172 of the disassembly guide section 156B in sequence in the guide groove 144, when the guide member 142 moves to be attached to the disassembly transition section 158B, the operator can sense that the operation is in place, the operator releases his hand, the end cap 134 is away from the main body 133 of the rolling brush body 130 under the action of the elastic member 140, the guide member 142 moves from the disassembly transition section 158B to the disassembly end section 160B, and finally, in the state shown in fig. 7 and 9, the guide member 142 reaches the open port 146, and the rolling brush body 130 can be removed from the floor brush body 120.

When the guide member 142 moves from the fixing position 148 to the detaching transition section 158B, the end cap 134 approaches the body, and the axial length of the entire roller brush body 130 is shortened; as the guide 142 moves from the removal transition 158B to the open port 146, the end cap 134 moves away from the body and the axial length of the entire roller brush body 130 increases. Therefore, the axial length of the roll brush body 130 may be changed during the disassembly process. Meanwhile, since the fixing portion 148 is spaced apart from the opened port 146 in the circumferential direction, the circumferential angle of the roll brush body 130 is also changed during the disassembly process.

As described above, in the present embodiment, in the process of attaching and detaching the brush body 130, the end cap 134 as the second member 132 moves axially and circumferentially with respect to the main body 133 as the first member 131, and axial displacement and circumferential displacement occur. The axial displacement provides a moving path for the installation and the disassembly of the rolling brush body 130, and the circumferential displacement can prevent the rolling brush body 130 from accidentally falling off from the main body 133, so that the structural design is very reasonable, and the operation is very simple.

The present embodiment further provides a vacuum cleaner, wherein the floor brush 100 is disposed on the vacuum cleaner, and the rolling brush body 130 of the floor brush 100 is convenient to disassemble and assemble, so that the vacuum cleaner of the present embodiment is more convenient to use, and is not described again.
