[0002] Currently, vacuum cleaners have evolved from traditional canister and upright models to gun-type vacuum cleaners, which have become the mainstream in the market. The gun-type vacuum cleaner has its main body located at the top, typically with a connecting wand and floor brush. Users hold the main body to operate the vacuum. The power supply is located on the main body. A problem with this type of vacuum cleaner is its high center of gravity, making storage and charging inconvenient. Currently, there are two main methods for storing and charging vacuum cleaners on the market: one involves using hooks on the wall for storage, where the power input contacts the charger's connector on the hook; the other involves using a floor-mounted stand with a bracket extending from the same height as the vacuum cleaner, also with the power input contacting the charger's connector on the stand. The first method requires hooks to be installed on the wall, which presents the problem of inconvenience in drilling holes in the wall; the second method requires a longer bracket, which significantly increases the production cost of the vacuum cleaner and the packaging volume.

[0024] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] It should be noted that in the description of this utility model, terms such as "upper," "lower," "left," "right," "front," and "rear," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] As shown in Figures 1 to 7, the vacuum cleaner floor brush structure of this utility model includes a floor brush body 1 and a floor brush connector 2. The floor brush body 1 is provided with a roller for patting the ground and a floor brush motor 12 for driving the roller to rotate. The floor brush connector 2 is provided with an airflow channel connecting the floor brush body 1 and the vacuum cleaner body 4. The side of the floor brush connector 2 is provided with a standing hook 3 for storing the vacuum cleaner. The end of the floor brush connector 2 facing the vacuum cleaner body 4 is provided with a first conductive part 5. The first conductive part 5 is used to connect to the internal power supply device 14 of the vacuum cleaner body 4 to supply power to the floor brush motor 12. The standing hook 3 is provided with a second conductive part 6 that is laterally electrically connected to the first conductive part 5. The second conductive part 6 is used to connect to an external power source to charge the internal power supply device 14 of the vacuum cleaner body 4. A switch device 7 for controlling the current of the floor brush motor 12 is provided between the first conductive part 5 and the floor brush motor 12. The switch device 7 is a normally closed micro switch.

[0028] Referring to Figures 1 to 4, the vacuum cleaner floor brush structure has at least a floor brush body 1 and a floor brush connector 2. The floor brush connector 2 is rotatably mounted on the floor brush body 1. A roller and a floor brush motor 12 that drives the roller to rotate and beat the ground are rotatably installed inside the floor brush body 1. The floor brush connector 2 is provided with an airflow channel, which can connect the floor brush body 1 and the vacuum cleaner body 4. When the fan inside the vacuum cleaner body 4 is working, it can suck the dust and debris beaten by the roller into the vacuum cleaner body 4 through the airflow channel of the floor brush body 1 and the floor brush connector 2.

[0029] Referring to Figures 3 to 7, a hook-shaped standing hook 3 is provided on the side of the floor brush connector 2 in the vertical direction. The vacuum cleaner can be hooked onto an object by means of the standing hook 3 to achieve storage of the vacuum cleaner. It should be noted that the vacuum cleaner includes the floor brush body 1, the floor brush connector 2 and the vacuum cleaner body 4. The floor brush connector 2 has a first conductive part 5 vertically installed at the end facing the vacuum cleaner body 4. The floor brush connector 2 has a second conductive part 6 installed horizontally inside the standing hook 3 and electrically connected to the first conductive part 5. The power supply device 14 inside the vacuum cleaner body 4 can be electrically connected to the floor brush motor 12 through the first conductive part 5 to supply power to the floor brush motor 12. The power supply device 14 inside the vacuum cleaner body 4 can be electrically connected to an external power source through the second conductive part 6 to charge the power supply device 14. A switch device 7 is electrically connected between the first conductive part 5 and the floor brush motor 12. The switch device is a normally closed micro switch. The switch device 7 is used to control the current on and off of this section of the circuit. When the external power source charges the power supply device 14 inside the vacuum cleaner body 4 through the second conductive part 6, the current between the first conductive part 5 and the floor brush motor 12 is disconnected to ensure the stability of charging the power supply device 14.

[0030] This application provides a standing hook 3 on the floor brush connector 2, with the first conductive part 5 vertically positioned at the end of the floor brush connector 2 and the second conductive part 6 horizontally positioned inside the standing hook 3. This allows the vacuum cleaner to be stored using the standing hook 3 while the first conductive part 5 and the second conductive part 6 provide power to the floor brush motor 12 from the power supply device 14 and charge the floor brush motor 12 from the external DC power supply, respectively. This design features convenient vacuum cleaner storage, a miniaturized vacuum cleaner structure, and high practicality.

[0031] In the preferred embodiment of the vacuum cleaner floor brush structure described above, the first conductive part 5 consists of two sets of conductive pins that connect to the positive and negative terminals of the power supply device 14, and the second conductive part 6 consists of two sets of conductive pins that can connect to the positive and negative terminals of an external power supply.

[0032] Referring to Figures 3 to 7, the conductive pins can be made of copper. This application distinguishes itself from traditional vacuum cleaners that use three conductive pins for conductive connection by limiting the first conductive part 5 and the second conductive part 6 to consist of two conductive pins. This reduces the problem of increased internal wiring in the vacuum cleaner due to the increased number of conductive pins, and reduces production costs.

[0033] In one or more embodiments, the switch device 7 is disposed within the standing hook 3.

[0034] Referring to Figures 6 and 7, the standing hook 3 has an internal cavity 31, and the switch device 7 is placed inside the cavity 31 of the standing hook 3. This arrangement can further reduce the space occupied by the switch device 7 and reasonably set the size of the floor brush body 1 and the floor brush connector 2.

[0035] In one or more embodiments, the first conductive part 5 and the second conductive part 6 are electrically connected through an elastic structure, which is a conductive spring 10 with conductive properties. Under the action of the conductive spring 10, the second conductive part 6 extends at least partially out of the standing hook 3 and is in a stationary position.

[0036] Referring to Figures 4 to 7, the standing hook 3 has a through hole for the conductive spring 10 to be inserted. Both the first conductive part 5 and the second conductive part 6 can extend into the through hole and contact the conductive spring 10, thereby achieving an electrical connection between the first conductive part 5 and the second conductive part 6. Furthermore, it should be noted that, to facilitate the connection of the second conductive part 6 to an external power source, one end of the second conductive part 6 needs to partially extend out of the standing hook 3. With the help of the elastic force of the conductive spring 10, the second conductive part 6 is pushed to a stationary position on the standing hook 3, so that the second conductive part 6 is pressed against the standing hook 3, while one end of the second conductive part 6 extends to the outer wall of the standing hook 3 for easy connection to an external power source.

[0037] In one or more embodiments, the side wall of the standing hook 3 is provided with a recessed groove 32, and an opening 33 is provided in the groove 32, and the trigger part 71 of the switch device 7 abuts against the opening 33.

[0038] Referring to Figures 5, 6, and 7, a groove 32 is provided on the lower part of the side wall of the standing hook 3. The groove 32 is connected to the receiving cavity 31 of the standing hook 3 through an opening 33. The switch device 7 has a trigger part 71, which abuts against the opening 33 and can partially extend into the groove 32. This arrangement can protect the trigger part 71 of the switch device 7, preventing external objects from accidentally touching the trigger part 71 of the switch device 7, which would cause the switch device 7 to disconnect the current between the first conductive part 5 and the floor brush motor 12, thus preventing the power supply device 14 in the vacuum cleaner body 4 from supplying power to the floor brush motor 12 and ensuring the stability of the floor brush motor 12 in controlling the roller operation.

[0039] In one or more embodiments, the trigger part 71 of the switch device 7 is provided with a roller 72, and the standing hook 3 is provided with a return spring 11. With the help of the elastic force of the return spring 11, the roller 72 is pressed against the opening 33; the cross section of the opening 33 is arc-shaped.

[0040] Referring to Figures 6 and 7, the return spring 11 has a first end and a second end. The first end of the return spring 11 is installed and pressed against the receiving cavity 31 of the standing hook 3, and the second end of the return spring 11 presses against the roller 72 of the trigger part 71 of the switch device 7. Without the action of other external forces, the roller 72 is always pressed against the opening 33 of the groove part 32 of the standing hook 3 by means of the elastic force of the return spring 11, reducing the possibility of failure of the trigger part 71 of the switch device 7. By configuring the cross section of the opening 33 into an arc shape to fit the roller 72 of the trigger part 71 of the switch device 7, the roller 72 can block the opening 33 of the groove part 32, reducing the possibility of dust and impurities entering the receiving cavity 31 of the standing hook 3.

[0041] In addition, referring to Figures 1, 2, 8, and 9, this utility model also provides a cleaning device, which has the vacuum cleaner floor brush structure in any of the above embodiments; a vacuum cleaner body 4, having a power supply device 14, the power supply device 14 being electrically connected to the floor brush motor 12 through a first conductive part 5; and a storage base 8, which is used to store the vacuum cleaner body 4 and the floor brush structure, so that the assembled vacuum cleaner body 4, floor brush connector 2, and floor brush body 1 are upright, so as to facilitate personnel to pick up and put away. The storage base 8 has a conductive sheet 9 that can contact the second conductive part 6, and the conductive sheet 9 is connected to an external power source through a power adapter 13.

[0042] Referring to Figures 1, 2, 8, and 9, the vacuum cleaner body 4 is connected to the floor brush body 1 via the floor brush connector 2. The power supply device 14 inside the vacuum cleaner body 4 is electrically connected to the floor brush motor 12 via a first conductive part 5. A switch device 7, a normally closed micro switch, is installed on the line between the first conductive part 5 and the floor brush motor 12 to control the current flow between them. The storage base 8 can be independent of the vacuum cleaner body 4, the floor brush body 1, and the floor brush connector 2. The storage base 8 is equipped with a conductive plate 9 that connects to an external DC power supply via a power adapter 13. The conductive plate 9 can connect to the floor brush body 1 via the power adapter 13. The second conductive part 6 is contacted, allowing the external DC power supply to charge the power device 14 inside the vacuum cleaner body 4. It should be noted that when the external DC power supply charges the power device 14 inside the vacuum cleaner body 4, the normally closed micro switch is in the open state. That is, the normally closed micro switch disconnects the current between the first conductive part 5 and the floor brush motor 12, avoiding the risk of circuit conflict that may occur when the vacuum cleaner is stored, such as the floor brush motor 12 power supply and the power device 14 charging function being activated at the same time, which could affect battery life or cause safety hazards. This further improves the stability of charging the power device 14.

[0043] In one or more embodiments, the receiving base 8 is provided with a support portion 81 having a receiving groove 811, and the conductive sheet 9 is disposed in the receiving groove 811. When the standing hook 3 is inserted into the receiving groove 811 and stored, the second conductive portion 6 can press against the conductive sheet 9. The receiving groove 811 is provided with a protruding structure 812 that is adapted to the groove portion 32. After the standing hook 3 is inserted into the receiving groove 811, the protruding structure 812 pushes the trigger portion 71 of the switching device 7 to exit the opening 33 toward the side away from the groove portion 32.

[0044] Referring to Figures 1, 8, and 9, the storage base 8 has a horizontally arranged placement platform 82 and a support part 81 installed on the placement platform 82. The top of the support part 81 has a receiving groove 811 that is adapted to the standing hook 3. The floor brush connector 2 enters the receiving groove 811 of the support part 81 by means of the bottom end of the standing hook 3, so that the floor brush connector 2 can be fixed by the support part 81 of the storage base 8, thereby realizing the storage of the floor brush body 1, the floor brush connector 2 and the vacuum cleaner body 4, making it convenient for people to pick up and put away the vacuum cleaner.

[0045] Referring to Figures 8 to 10, a conductive sheet 9 is installed in the receiving groove 811 of the support part 81 of the storage base 8. The bottom side wall of the receiving groove 811 of the support part 81 is provided with a protruding structure 812 adapted to the groove 32 of the standing hook 3. When the vacuum cleaner needs to be stored, first place the floor brush body 1 horizontally on the placement platform 82 of the storage base 8, and make the floor brush connector 2 perpendicular to the floor brush body 1. Then, place the bottom end of the standing hook 3 of the floor brush connector 2 into the receiving groove 811 of the support part 81 of the storage base 8 in the vertical direction. When the bottom end of the standing hook 3 moves to a stationary position in the receiving groove 811, the conductive sheet 9 contacts the second conductive part 6. Under the action of the conductive spring 10, the end of the second conductive part 6 extending out of the standing hook 3 can press against the conductive sheet 9, thereby ensuring the stability of the external DC power supply for charging the power supply device 14.

[0046] Furthermore, referring to Figures 8 to 10, when the bottom end of the stand hook 3 moves to a stationary position within the receiving groove, the protruding structure 812 provided in the receiving groove can enter the recessed portion 32 of the stand hook 3, thereby pushing the roller 72 provided in the trigger portion 71 of the normally closed micro switch toward the receiving cavity 31 of the stand hook 3. This causes the micro switch to disconnect the current between the first conductive portion 5 and the floor brush motor 12, so that when the vacuum cleaner is stored in the storage base 8, it only has the function of charging the power supply device 14, and does not have the function of supplying power to the floor brush motor 12. With this arrangement, it is possible to enable an external power source to charge the power supply device 14 inside the vacuum cleaner body 4 when the vacuum cleaner is stored in the storage base 8.

[0047] The micro switch 7 is placed inside the standing hook 3, which is only one implementation of this technology. The micro switch 7 is placed inside the floor brush housing 1, and the micro switch 7 is triggered by the storage seat 8 or the floor brush connector 2 is rotated when the vacuum cleaner is stored to trigger the micro switch 7 to control the on and off of the floor brush motor 12 inside the floor brush body 1. This will not be repeated, and all of them are included in the scope of protection of this technology patent.

[0048] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
