[0002] With the improvement of social productivity, people's lives are getting better day by day. The demand for improved living environment and the change of consumption concept have led to an increasing demand for the use of vacuum cleaners.

[0003] The working principle of a vacuum cleaner is to use the high-speed rotation of the motor to form a vacuum inside the main unit, and use the high-speed airflow generated to suck in the garbage airflow from the suction port of the floor brush, leaving the garbage in the main unit and then expelling the clean airflow. Therefore, the floor brush is an indispensable part of the vacuum cleaner.

[0004] A floor brush usually includes a floor brush body and a roller brush body detachably mounted on the floor brush body. The rotation of the roller brush body can greatly improve the cleaning efficiency of the vacuum cleaner. However, the roller brush body is in contact with the ground for a long time and is particularly easy to be entangled with hair and other filamentous garbage. Therefore, users often need to remove the roller brush body from the floor brush body to clean it.

[0005] Since the floor brush body and the end of the roller brush body are usually made of plastic and have a small amount of elasticity, users of existing floor brushes generally have to overcome the elasticity of the floor brush body and the roller brush body to disassemble and assemble the roller brush body, which is not convenient. Summary of the invention

[0016] As a further improvement of an embodiment of the present invention, the number of the guide members is multiple, the multiple guide members are evenly distributed in the circumferential direction of the second component, and the number of the guide grooves is the same as the number of the guide members and matches one by one.

[0017] Compared with the prior art, the beneficial effect of the present invention is that the roller brush body can be disassembled and assembled more easily and conveniently through the axial movement and circumferential movement of the second component relative to the first component.

[0041] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0042] It should be understood that in the description of the present invention, the terms "first", "second", etc. are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0043] In the present invention, unless otherwise clearly specified and limited, the terms "connected", "connection" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the present invention, unless otherwise clearly stipulated and limited, a first feature being “on” or “under” a second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them.

[0045] See also Figure 1 and Figure 2 A floor brush 100 provided in a specific embodiment of the present invention includes a floor brush body 120 and a roller brush body 130 detachably mounted on the floor brush body 120 .

[0046] Thus, the roller brush body 130 can be removed from the floor brush body 120 to clean up the debris on the roller brush body 130 , thereby improving the cleaning efficiency of the floor brush 100 .

[0047] See also Figures 2 to 4 In the present embodiment, preferably, the roller brush body 130 includes a first component 131 and a second component 132 connected to each other, and the second component 132 moves relative to the first component 131, so that the roller brush body 130 and the floor brush body 120 are detachably installed.

[0048] In the present embodiment, the first component 131 is the main body 133 of the roller brush body 130 , and the second component 132 is the end cover 134 provided at one end of the main body 133 .

[0049] The main body 133 of the roller brush 130 is usually provided with hair or hair planting to improve the cleaning efficiency. Figure 1 As shown, the main body 133 is covered with fluff.

[0050] The second component 132 moves axially and circumferentially relative to the first component 131, so that the roller brush body 130 and the floor brush body 120 can be detachably installed, which is convenient and quick. Here, the axial movement and the circumferential movement can occur simultaneously or in sequence, that is, the circumferential movement occurs simultaneously with the axial movement. At this time, the circumferential movement occurs passively (such as Figures 5 to 12 The structure described above may occur automatically or actively (such as manual rotation by the user, the structure may be a relatively simple U-shape). Of course, the circumferential movement may also be performed after the axial movement is completed. Here, simultaneously or sequentially is not limited.

[0051] Preferably, in this embodiment, an elastic member 140 is provided between the first member 131 and the second member 132 .

[0052] During installation, the second component 132 is pressed to overcome the force of the elastic component 140 so that the second component 132 moves axially and circumferentially relative to the first component 131 . The second component 132 is released and moves to the installation position under the action of the elastic component 140 .

[0053] During disassembly, the second component 132 is pressed against the force of the elastic component 140 to make the second component 132 move axially and circumferentially relative to the first component 131 , and the second component 132 is released, and the second component 132 moves to the disassembly position under the action of the elastic component 140 .

[0054] The elastic member 140 assists the relative movement between the second member 132 and the first member 131, and the structure is simple and reasonable. In particular, when the roller brush body 130 is in the installation position, the elastic member 140 exerts a force on the second member 132 to move away from the first member 131, so that the roller brush body 130 can be reliably maintained in the installation position, and the use of the floor brush 100 is more stable and reliable.

[0055] As mentioned above, the second component 132 moves axially and circumferentially relative to the first component 131, so that the roller brush body 130 and the floor brush body 120 are detachably connected.

[0056] For details, please combine Figure 2 , Figure 5 and Figure 6 A guide mechanism is provided between the second component 132 and the floor brush body 120, and the guide mechanism includes a guide member 142 arranged on the second component 132 and a guide groove 144 arranged on the floor brush body 120. The guide groove 144 includes an open port 146, a fixed position 148 closed at the far end, and a groove body 150 extending between the port 146 and the fixed position 148. The port 146 and the fixed position 148 are spaced a certain distance apart in the circumferential direction, and the groove body 150 extends a certain distance in the axial direction.

[0057] The guide groove 144 can limit the movement path of the guide member 142, so that the guide member 142 moves along a desired path, thereby making the second component 132 move relative to the first component 131 in a desired movement mode to complete the assembly and disassembly of the roller brush body 130.

[0058] The open port 146 can make it easier to install and disassemble the roller brush body 130. During installation, the guide member 142 enters from the open port 146 to install the roller brush body 130 to the floor brush body 120; during disassembly, the guide member 142 exits from the open port 146 to ensure that the roller brush body 130 is removed from the floor brush body 120, that is, during the disassembly process, the guide member 142 moves to the open port 146, and the second member 132 is located at the disassembly position.

[0059] Since the guide member 142 moves in the guide groove 144, the fixing position 148 is a part of the guide groove 144, and therefore, the fixing position 148 cannot be completely closed. The far end closure of the fixing position 148 means that the fixing position 148 is closed at the end of the second component 132 in the direction away from the first component 131. The far end closed fixing position 148 can fix the second component 132 at a position away from the first component 131, so that the roller brush body 130 is fixed relative to the brush body 120. In other words, during the installation process, the guide member 142 abuts against the fixing position 148, and the second component 132 is located at the installation position.

[0060] The port 146 and the fixing position 148 are spaced a certain distance in the circumferential direction, so that the port 146 and the fixing position 148 are staggered, which can prevent the guide member 142 from accidentally sliding out of the port 146, and ensure the reliable installation of the roller brush body 130. The port 146 and the fixing position 148 are spaced a certain distance in the circumferential direction, so that the guide member 142 generates circumferential displacement when moving in the guide groove 144; the groove body 150 extends a certain distance in the axial direction. The guide member 142 generates axial displacement when moving in the guide groove 144. Therefore, the guide member 142 generates axial and circumferential displacements at the same time when moving in the guide groove 144, so that the second component 132 generates axial and circumferential displacements at the same time when moving relative to the first component 131, and ensures the reliable disassembly and assembly of the roller brush body 130.

[0061] Thus, when the guide member 142 moves from the open port 146 to the fixed position 148 in the guide groove 144, the roller brush body 130 is located at the installation position, and the roller brush body 130 is installed on the floor brush body 120. When the guide member 142 moves from the fixed position 148 to the open port 146 in the guide groove 144, the roller brush body 130 is located at the disassembly position and can be removed from the floor brush body 120.

[0062] 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.

[0063] In this preferred embodiment, although the two ends of the installation section 152 and the removal section 154 are the same, both are open ports 146 and fixed positions 148, the installation section 152 and the removal section 154 are two different paths. The installation section 152 and the removal section 154 are separated by a partition 155.

[0064] Therefore, the installation section 152 and the disassembly section 154 can not only be designed separately, but also avoid misoperation.

[0065] Preferably, in this embodiment, the installation section 152 and the removal section 154 both include a guide section 156A / 156B, a transition section 158A / 158B, and a terminal section 160A / 160B which are connected in sequence.

[0066] That is, the installation section 152 includes the installation guide section 156A, the installation transition section 158A, and the installation end section 160A connected in sequence. The disassembly section 154 includes the disassembly guide section 156B, the disassembly transition section 158B, and the disassembly end section 160B connected in sequence.

[0067] Preferably, in this embodiment, an elastic member 140 is provided between the first member 131 and the second member 132, and the guide member 142 overcomes the force of the elastic member 140 and moves from the guide section 156A / 156B to the transition section 158A / 158B. Under the action of the elastic member 140, the guide member 142 moves from the transition section 158A / 158B to the final section 160A / 160B.

[0068] Specifically, during installation, the operator overcomes the force of the elastic member 140 to push the second component 132, thereby pushing the guide member 142 from the open port 146 into the installation guide section 156A and moving within the installation guide section 156A. 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, and the operator can release the second component 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 it abuts against the fixed position 148, and the roller brush body 130 is installed in place.

[0069] During disassembly, the operator overcomes the force of the elastic member 140 to push the second component 132, thereby pushing the guide member 142 from the fixed position 148 into the disassembly guide section 156B and moving within the disassembly guide section 156B. 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 component 132, and 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 it is aligned with the open port 146. The roller brush body 130 can be removed from the floor brush body 120.

[0070] In this embodiment, by combining the force applied by the operator and the force of the elastic member 140 and by reasonably designing the installation section 152 and the disassembly section 154 , the roller brush body 130 can be easily assembled and disassembled.

[0071] Preferably, in this embodiment, the guide section 156A / 156B includes a first section 171 and a second section 172 that are arranged at an angle, the transition section 158A / 158B is connected to the second section 172, and the transition section 158A / 158B and the first section 171 are staggered by a certain distance in the circumferential direction.

[0072] Therefore, when the operator releases the second component 132, when the guide member 142 moves under the action of the elastic member 140, the transition section 158A / 158B is not directly connected to the first section 171, and the transition section 158A / 158B and the first section 171 are staggered by a certain distance in the circumferential direction, which can prevent the guide member 142 from returning from the transition section 158A / 158B to the guide section 156A / 156B, and the guide member 142 can only move from the transition section 158A / 158B to the end section 160A / 160B, thereby ensuring reliable disassembly and assembly of the roller brush body 130. In addition, the guide design of the second section 172 allows the operator to press the second component 132 to make the guide member 142 smoothly reach the transition section 158A / 158B without the need for additional rotation, which is simpler and more convenient to operate.

[0073] In the present embodiment, preferably, the guide section 156A / 156B and the transition section 158A / 158B have different extension line types.

[0074] When the operator presses the second component 132 and the guide member 142 moves in the guide groove 144, when the operator feels that the shape of the guide groove 144 abutted by the guide member 142 has changed, at this time, the guide member 142 enters the transition section 158A / 158B with different linear shapes, the operator can judge that the operation is in place, the operator can release the hand, and the roller brush body 130 can be disassembled and assembled under the action of the elastic member 140. Therefore, in this embodiment, by designing the guide sections 156A / 156B and transition sections 158A / 158B with different extension linear shapes, it can help the operator to judge whether the operation is in place.

[0075] In this embodiment, the extension line shape of the transition section 158A / 158B matches the extension line shape of the cross section of the guide member 142. This allows the guide member 142 to fit well with the transition section 158A / 158B. When the operator senses this fit, the operator can accurately determine that the operation is in place, and the design is very reasonable.

[0076] Specifically, in this embodiment, the main body 133 of the guide member 142 is cylindrical, and the transition section 158A / 158B extends in an arc, so that the guide member 142 fits well with the transition section 158A / 158B. Those skilled in the art can imagine that the shapes of the cross-sections of the guide member 142 and the transition section 158A / 158B can be designed as needed, and any scheme that adopts the same or similar scheme as this embodiment is covered within the scope of protection of the present invention.

[0077] Preferably, in this embodiment, the number of the guide members 142 is multiple, the multiple guide members 142 are evenly distributed in the circumferential direction of the second component 132, and the number of the guide grooves 144 is the same as the number of the guide members 142 and matches one by one.

[0078] Specifically, in this embodiment, there are three guide members 142, and the end caps 134 of the three guide members 142 are evenly spaced in the circumferential direction. Correspondingly, the three guide grooves 144 are evenly spaced in the circumferential direction on the floor brush body 120, specifically on the inner wall of the receiving groove of the floor brush body 120 that receives the roller brush body 130. This can make the roller brush body 130 and the floor brush body 120 more evenly stressed, and the installation is more reliable.

[0079] Those skilled in the art can appreciate that the number of guide members 142 and guide slots 144 can be designed as needed, and does not constitute a limitation on the protection scope of the present invention. All solutions that are the same or similar to the present embodiment are covered by the protection scope of the present invention.

[0080] The following is a more complete description of the installation process of the roller brush body 130.

[0081] When installing, see Figure 7 First, adjust the angle of the roller brush body 130 so that the three guide members 142 on the end cover 134 of the roller brush body 130 are aligned with the open ends 146 of the three guide grooves 144 on the floor brush body 120.

[0082] Then see Figures 8 to 10 The operator overcomes the force of the elastic member 140 and applies force to the end cover 134 in the direction close to the main body 133 of the roller brush body 130, so that the guide member 142 moves in the guide groove 144 along the first section 171 and the second section 172 of the installation guide section 156A in sequence. When the guide member 142 moves to fit with the installation transition section 158A, the operator can feel that the operation is in place. The operator releases his hand, and the end cover 134 moves away from the main body 133 of the roller brush body 130 under the action of the elastic member 140. The guide member 142 moves from the installation transition section 158A to the installation end section 160A, and finally abuts against the fixed position 148.

[0083] At this time, see Fig.11 The roller brush body 130 is securely mounted on the floor brush body 120 .

[0084] When the guide member 142 moves from the open port 146 to the installation transition section 158A, the end cover 134 approaches the body, and the axial length of the entire roller brush body 130 is shortened; when the guide member 142 moves from the installation transition section 158A to the fixed position 148, the end cover 134 moves away from the body, and the axial length of the entire roller brush body 130 becomes longer. Therefore, during the installation process, the axial length of the roller brush body 130 will change. At the same time, since the open port 146 and the fixed position 148 are spaced a certain distance in the circumferential direction, during the installation process, the circumferential angle of the roller brush body 130 will also change.

[0085] The following is a more complete description of the disassembly process of the roller brush body 130.

[0086] When disassembling, see Fig.10 and Fig.12 The operator overcomes the force of the elastic member 140 and applies force to the end cover 134 in the direction close to the main body 133 of the roller brush body 130, so that the guide member 142 moves in the guide groove 144 along the first section 171 and the second section 172 of the disassembly guide section 156B in sequence. When the guide member 142 moves to fit the disassembly transition section 158B, the operator can feel that the operation is in place. The operator releases his hand, and the end cover 134 moves away from the main body 133 of the roller 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 returns to the position where the end cover 134 is located. Figure 7 and Fig. 9 In the state shown, the guide member 142 reaches the open port 146 , and the roller brush body 130 can be removed from the floor brush body 120 .

[0087] When the guide member 142 moves from the fixed position 148 to the disassembly transition section 158B, the end cover 134 approaches the body, and the axial length of the entire roller brush body 130 is shortened; when the guide member 142 moves from the disassembly transition section 158B to the open port 146, the end cover 134 moves away from the body, and the axial length of the entire roller brush body 130 becomes longer. Therefore, during the disassembly process, the axial length of the roller brush body 130 will change. At the same time, since the fixed position 148 and the open port 146 are spaced a certain distance in the circumferential direction, during the disassembly process, the circumferential angle of the roller brush body 130 will also change.

[0088] In summary, in this embodiment, during the assembly and disassembly process of the roller brush body 130, the end cover 134 as the second component 132 moves axially and circumferentially relative to the main body 133 as the first component 131, resulting in axial displacement and circumferential displacement. The axial displacement provides a moving path for the assembly and disassembly of the roller brush body 130, and the circumferential displacement can prevent the roller brush body 130 from accidentally falling off from the main body 133. The structural design is very reasonable and the operation is very simple.

[0089] This embodiment further provides a vacuum cleaner, which is provided with the above-mentioned floor brush 100. Since the roller brush body 130 of the floor brush 100 is easy to assemble and disassemble, the use of the vacuum cleaner of this embodiment is also more convenient, which will not be described in detail.
