Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a floor brush assembly and a vacuum cleaner. Background Technology

[0002] Vacuum cleaners are becoming increasingly popular with consumers due to their ease of use. A typical vacuum cleaner includes a floor brush assembly, which comprises a main brush body and a rotating component rotatably connected to the brush body. This rotating component allows users to easily change the cleaning direction as needed, facilitating thorough cleaning of surfaces.

[0003] In existing technology, in order to achieve the switching between self-locking and free rotation of a vacuum cleaner, a locking protrusion is set on the rotating component, and a spring with a protrusion is set on the floor brush body. The self-locking of the vacuum cleaner is achieved by the cooperation of the locking protrusion and the protrusion of the spring. However, since locking or unlocking the floor brush component requires the locking protrusion of the rotating component to press against the spring and deform the spring, the lifespan of the spring is easily shortened by long-term or frequent use, which reduces the lifespan of the floor brush component. Utility Model Content

[0004] The purpose of this utility model is to propose a floor brush assembly and a vacuum cleaner, which solves the technical problem in the prior art that the floor brush assembly is locked or unlocked by the cooperation of a latch and a spring with a protrusion, resulting in a short service life of the spring and a reduced service life of the floor brush assembly.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides a floor brush assembly, including a floor brush body and a rotating assembly. The rotating assembly includes a rotating shaft rotatably connected to the floor brush body, and a floor brush latch is provided on the rotating shaft. A snap-fit ​​structure is provided inside the floor brush body. The snap-fit ​​structure can engage with the floor brush latch in a locked position and can unlock from the floor brush latch in an unlocked position.

[0007] The floor brush body is also provided with a driving component, which abuts against the buckle structure and drives the buckle structure to approach the floor brush latch.

[0008] The floor brush assembly uses a rotating shaft to set the floor brush lock. A snap-fit ​​structure is located inside the floor brush body. This snap-fit ​​structure can engage with the floor brush lock in the locked position and unlock in the unlocked position, thus enabling the vacuum cleaner to switch between self-locking and free-rotating modes. A drive component abuts against the snap-fit ​​structure, driving it closer to the floor brush lock to reset it. The locking and unlocking of the floor brush assembly is achieved through the drive component, preventing elastic deformation of the snap-fit ​​structure and floor brush lock, thereby extending the lifespan of the floor brush assembly.

[0009] As a preferred embodiment of the aforementioned floor brush assembly, the snap-fit ​​structure includes:

[0010] The rotating part is rotatably mounted on the base of the floor brush body;

[0011] The hook is connected to the rotating part via a connecting part, and the hook is used to engage with the floor brush lock.

[0012] The snap-fit ​​structure is rotatably mounted on the base of the floor brush body via a rotating part. It can engage with the floor brush lock via a hook. The rotating part and the hook are connected into a whole structure via a connecting part. This snap-fit ​​structure is simple in structure and easy to manufacture.

[0013] As a preferred embodiment of the above-mentioned floor brush assembly, a partition plate is provided on the side of the connecting part facing the floor brush latch and located below the hook;

[0014] The outer periphery of the floor brush latch has a protruding latch structure, and the latch structure is provided with a plug groove. The hook engages with the latch structure, and the partition plate is inserted into the plug groove.

[0015] The combination of the aforementioned partition plate and the insertion slot can prevent the rotating component from displacing relative to the brush body in a direction perpendicular to the partition plate when the snap-fit ​​structure and the locking structure are engaged, thus limiting the rotation of the component.

[0016] As a preferred embodiment of the above-mentioned floor brush assembly, the driving member is located on the side of the buckle structure away from the floor brush latch, the side of the buckle structure facing the driving member is provided with a first limiting groove, the base of the floor brush body is provided with a second limiting groove, and the two ends of the driving member are respectively limited within the first limiting groove and the second limiting groove.

[0017] The first and second limiting grooves limit the two ends of the driving component.

[0018] As a preferred embodiment of the above-mentioned floor brush assembly, the second limiting groove has a U-shaped structure, and the opening of the U-shaped structure faces the upper cover of the floor brush body;

[0019] The upper cover of the brush body is provided with a sealing part at the position corresponding to the second limiting groove. The sealing part can extend into the U-shaped structure through the opening of the U-shaped structure to seal the end of the driving member in the U-shaped structure.

[0020] The second limiting groove has a U-shaped structure, with the opening of the U-shaped structure facing the top cover of the brush body, which facilitates the installation of the drive component; the sealing part can seal the opening of the U-shaped structure to prevent the end of the drive component inside the U-shaped structure from coming out of the U-shaped structure.

[0021] As a preferred embodiment of the above-mentioned floor brush assembly, the axis of the rotating component is located on the side of the longitudinal axis of the rotating component away from the floor brush body, and the side of the rotating component close to the floor brush body is supported on the floor brush body.

[0022] When the floor brush assembly is locked, the axis of the rotating assembly's pivot is located on the side of the rotating assembly's longitudinal axis away from the floor brush body. The center of gravity of the rotating assembly and the structure above it falls on the floor brush body, and the side of the rotating assembly closest to the floor brush body is supported on the floor brush body, thereby preventing the vacuum cleaner from tipping over and making it more stable.

[0023] The center of gravity of the rotating assembly and the structure above it rests on the main body of the floor brush. The side of the rotating assembly closest to the main body of the floor brush is supported on the main body of the floor brush, thereby preventing the vacuum cleaner from tipping over and making it more stable.

[0024] As a preferred embodiment of the above-mentioned floor brush assembly, a cavity structure for accommodating the roller brush is formed between the upper cover and the base of the floor brush body. A guide groove is provided on the base, and the width of the guide groove gradually narrows in the direction toward the cavity structure to form a communication port connected to the cavity structure.

[0025] The guide groove and connecting port can guide the dust collection, allowing the dust to enter the cavity structure more smoothly.

[0026] As a preferred embodiment of the above-mentioned floor brush assembly, the opening width W of the connecting port is greater than 15mm;

[0027] The distance H between the top edge of the connecting port and the bottom surface of the wheel on the main body of the floor brush is greater than 8mm;

[0028] The opening angle α of the guide groove is in the range of 90°-150°.

[0029] The above parameter settings enable dust collection and prevent large dust particles from being unable to enter the cavity structure due to an excessively small connection opening.

[0030] As a preferred embodiment of the aforementioned floor brush assembly, the base is provided with a plurality of guide grooves, and the bottom of each guide groove is provided with a communication port that communicates with the cavity structure.

[0031] The design of multiple guide slots and connecting ports improves the efficiency of dust collection.

[0032] This utility model also provides a vacuum cleaner, including the above-mentioned floor brush assembly. The vacuum cleaner also includes a handle assembly and a body. The top end of the handle assembly is connected to the body, and the bottom end of the handle assembly is connected to the end of the rotating assembly that is not connected to the floor brush body.

[0033] The vacuum cleaner can achieve self-locking and extend its service life through the aforementioned floor brush assembly.

[0034] The beneficial effects of this utility model are:

[0035] The floor brush assembly proposed in this utility model features a floor brush lock set by a rotating shaft. A snap-fit ​​structure is located within the floor brush body. This snap-fit ​​structure can engage with the floor brush lock in a locked position and unlock in an unlocked position, thus enabling the vacuum cleaner to switch between self-locking and free rotation modes. A driving component abuts against the snap-fit ​​structure, driving it closer to the floor brush lock to reset it. The locking and unlocking of this floor brush assembly are achieved through the driving component, preventing elastic deformation of the snap-fit ​​structure and the floor brush lock, thereby extending the service life of the floor brush assembly.

[0056] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0057] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0058] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0059] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0060] like Figure 1 and Figure 2 As shown, this embodiment provides a vacuum cleaner, including a floor brush assembly 100, a handle assembly 200, and a body 300. The top end of the handle assembly 200 is connected to the body 300, and the bottom end of the handle assembly 200 is connected to the floor brush assembly 100. The body 300 includes a dust cup 301 and a handle 302 disposed on the dust cup 301. The top end of the handle assembly 200 extends into the dust cup 301 and is fixed therein. The body 300 also includes a filter device, a negative pressure device, etc.

[0061] When using the vacuum cleaner, the user holds the handle 302 of the vacuum cleaner, and the floor brush assembly 100 contacts the area to be cleaned. The negative pressure device is activated, which generates a strong suction. The air carrying dust and debris enters the floor brush assembly 100 and then enters the body 300 through the handle assembly 200. The dust, debris and other impurities carried are filtered by the filter device and finally fall into the dust cup 301.

[0062] Optionally, the vacuum cleaner also includes a dust collection station 400, a floor brush assembly 100, a handle assembly 200, and a body 300 assembled together to form the main body of the vacuum cleaner. The main body of the vacuum cleaner can be supported on the dust collection station 400 and can be used detached from the dust collection station 400. The dust collection station 400 provides a place for the main body of the vacuum cleaner and also performs functions such as dust collection and charging. The installation method and connection structure of the dust collection station 400 and the main body of the vacuum cleaner are existing technologies and will not be described in detail here.

[0063] In the prior art, the floor brush assembly includes a floor brush body and a rotating component. In order to achieve the switching between self-locking and free rotation of the vacuum cleaner, a locking protrusion is set on the rotating component, and a spring with a protrusion is set on the floor brush body. The self-locking of the floor brush assembly is achieved by the cooperation of the locking protrusion and the protrusion of the spring. However, since the locking or unlocking of the floor brush assembly requires the locking protrusion of the rotating component to press against the spring and deform the spring, the lifespan of the spring is easily shortened by long-term or frequent use, thus reducing the lifespan of the floor brush assembly.

[0064] To solve the above problems, such as Figures 3-10 As shown, this embodiment provides a floor brush assembly 100, which includes a floor brush body 1 and a rotating assembly 2. The rotating assembly 2 is connected to the bottom end of the handle assembly 200, and a rotating shaft 20 (see [reference]) is horizontally arranged at the lower end of the rotating assembly 2. Figure 13 A floor brush lock 21 is rotatably connected to the floor brush body 1. A latching structure 11 is rotatably installed inside the floor brush body 1. The latching structure 11 can engage with the floor brush lock 21 in the locked position and unlock from the floor brush lock 21 in the unlocked position. A driving component 12 is also installed inside the floor brush body 1. The driving component 12 abuts against the latching structure 11 and can drive the latching structure 11 to rotate closer to the floor brush lock 21, so that the latching structure 11 rotates from the unlocked position back to the locked position. The locked position is the position where the latching structure 11 engages with the floor brush lock 21, and the unlocked position is the position of the latching structure 11 at the moment of unlocking.

[0065] The floor brush assembly 100 is equipped with a floor brush lock 21 via the rotating shaft 20 of the rotating assembly 2. A latching structure 11 is rotatably installed inside the floor brush body 1. The latching structure 11 can engage with the floor brush lock 21 in the locked position and unlock from the floor brush lock 21 in the unlocked position, thereby realizing the vacuum cleaner's ability to switch between self-locking and free rotation. The driving component 12 abuts against the latching structure 11, driving the latching structure 11 closer to the floor brush lock 21, so that the latching structure 11 is reset from the unlocked position to the locked position, thus realizing the reset of the latching structure 11. The locking and unlocking of the floor brush assembly 100 is achieved by the driving component 12 driving the rotation of the latching structure 11. The latching structure 11 and the floor brush lock 21 will not undergo elastic deformation, thus extending the service life of the floor brush assembly 100.

[0066] like Figure 11 and Figure 12 As shown, the snap-fit ​​structure 11 includes a rotating part 111, a hook 112, and a connecting part 113. The rotating part 111 is rotatably mounted on the base 13 of the floor brush body 1. The hook 112 is connected to the rotating part 111 via the connecting part 113 and is used to engage with the floor brush latch 21. The snap-fit ​​structure 11 is rotatably mounted on the base 13 of the floor brush body 1 via the rotating part 111. The hook 112 enables engagement with the floor brush latch 21. The connecting part 113 connects the rotating part 111 and the hook 112 into a single structure. This snap-fit ​​structure 11 has a simple structure and is easy to manufacture.

[0067] Furthermore, such as Figure 12 As shown, a partition plate 114 is provided on the side of the connecting part 113 facing the floor brush latch 21 and located below the hook 112; as Figure 13 As shown, the outer periphery of the floor brush latch 21 has a protruding latch structure 211, and the latch structure 211 is provided with an insertion groove 2111. The hook 112 engages with the latch structure 211, and the partition plate 114 is inserted into the insertion groove 2111. The cooperation between the partition plate 114 and the insertion groove 2111 can prevent the rotating component 2 from displacing relative to the floor brush body 1 in a direction perpendicular to the partition plate 114 when the latch structure 11 and the latch structure 211 are engaged, thus limiting the rotation component 2.

[0068] like Figure 11 As shown, in this embodiment, the driving member 12 is disposed on the side of the latching structure 11 away from the floor brush latch 21. The driving member 12 is in a compressed state, elastically abutting against the latching structure 11. In other embodiments, the driving member 12 can also be disposed on the side of the latching structure 11 closer to the floor brush latch 21. In this case, the driving member 12 is in a stretched state, pulling the latching structure 11 to abut against the floor brush latch 21.

[0069] Furthermore, a first limiting groove 1131 is provided on the side of the latching structure 11 facing the driving member 12, such as... Figure 10 As shown, a second limiting groove 131 is provided on the base 13 of the floor brush body 1. In this embodiment, the driving component 12 can be a spring. The two ends of the spring are respectively limited within the first limiting groove 1131 and the second limiting groove 131. The first limiting groove 1131 and the second limiting groove 131 limit the two ends of the spring.

[0070] In other alternative embodiments, the drive element 12 may be an electrically driven component, enabling the drive element 12 to drive the latch structure 11 from the unlocked position to the locked position.

[0071] In this embodiment, the second limiting groove 131 has a U-shaped structure, with the opening of the U-shaped structure facing the upper cover 14 of the floor brush body 1, thereby facilitating the installation of the drive component 12. A sealing part 141 is provided at the corresponding position of the upper cover 14 of the floor brush body 1 and the second limiting groove 131 (see...). Figure 7 and Figure 8 The sealing part 141 can extend into the U-shaped structure through the opening of the U-shaped structure to seal the end of the drive member 12 inside the U-shaped structure. The sealing part 141 can block the opening of the U-shaped structure and prevent the end of the drive member 12 inside the U-shaped structure from coming out of the U-shaped structure.

[0072] Optionally, the axis of the rotating shaft 20 of the rotating component 2 is located on the side away from the floor brush body 1 on the longitudinal axis of the rotating component 2, and the side of the rotating component 2 close to the floor brush body 1 is supported on the floor brush body 1. The center of gravity of the rotating component 2 and the structure above it falls on the floor brush body 1, and the side of the rotating component 2 close to the floor brush body 1 is supported on the floor brush body 1, thereby preventing the vacuum cleaner from tipping over and making it more stable.

[0073] Optionally, such as Figure 14 As shown, a cavity structure 15 for accommodating the roller brush is formed between the upper cover 14 and the base 13 of the brush body 1. The base 13 has a suction port 132 communicating with the cavity structure 15, and a guide groove 133 is also provided on the base 13. The width of the guide groove 133 gradually narrows towards the cavity structure 15, forming a connecting opening 134 that communicates with the cavity structure 15. The guide groove 133 and the connecting opening 134 guide dust collection, allowing dust to enter the cavity structure 15 more smoothly. Preferably, as shown... Figure 15As shown, the opening width W of the connecting port 134 is greater than 15mm, meaning the opening width W of the connecting port 134 can be 16mm, 17mm, 18mm, etc., and the specific value can be designed according to the requirements; the distance H between the top edge of the connecting port 134 and the bottom surface of the wheel on the brush body 1 is greater than 8mm, and H can be 9mm, 10mm, 11mm, 12mm, etc., and the specific value can be designed according to the requirements; the opening angle α of the guide groove 133 is in the range of 90°-150°, and the opening angle α of the guide groove 133 can be 90°, 100°, 110°, 120°, 130°, 140°, 150°, etc., and the specific value can be designed according to the requirements. The setting of the above parameters can realize dust collection and avoid the situation where large dust particles cannot enter the cavity structure 15 due to the connecting port 134 being too small.

[0074] Optionally, the base 13 is provided with multiple guide grooves 133, and the bottom of each guide groove 133 is provided with a communication port 134 that communicates with the cavity structure 15. The arrangement of multiple guide grooves 133 and communication ports 134 improves the dust collection efficiency.

[0075] When the vacuum cleaner body is locked upright, the floor brush body 1 is placed horizontally, and the top of the handle assembly 200 rotates toward the direction close to the floor brush body 1 so that the floor brush latch 21 engages with the latch structure 11 located in the locked position. At this time, part of the housing of the rotating assembly 2 is supported on the floor brush body 1.

[0076] When it is necessary to unlock the floor brush latch 21 and the latching structure 11, the top of the handle assembly 200 rotates away from the floor brush body 1, so that the latching structure 11 rotates towards the compression drive member 12, that is, the latching structure 11 rotates from the locked position to the unlocked position, thereby disengaging the floor brush latch 21 from the latching structure 11.

[0077] After the local brush lock 21 and the latch structure 11 are unlocked, the drive component 12 drives the latch structure 11 to reset from the unlocked position to the locked position.

[0078] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
