Technical Field
[0001] This utility model relates to the field of vacuum cleaner technology, and more specifically, to a floor brush roller pop-out structure. Background Technology
[0002] Vacuum cleaners are a type of cleaning equipment. They use an electric motor to drive the blades to rotate at high speed, creating negative air pressure inside a sealed housing, which in turn sucks up dust and debris. The floor brush roller is an important component of a vacuum cleaner and can effectively remove dirt and debris from the floor.
[0003] Application number CN217039946U discloses a vacuum cleaner with a detachable roller brush ejection structure. The vacuum cleaner comprises a floor brush body, a roller brush assembly, a locking assembly, and an ejection assembly. An inner shell is provided on one side of the floor brush body. One end of the roller brush assembly is snapped onto the inner shell. The locking assembly includes a locking block and a release button. The locking block is elastically connected to the inner shell, and its locking tongue is inserted into a slot in the roller brush assembly. The release button is slidably connected to the inner shell, with its bottom abutting against the locking block. The contact surface between the release button and the locking block is inclined. The ejection assembly includes a spring block, which is elastically connected to the inner shell, with its end abutting against the roller brush assembly. This provides a vacuum cleaner with a detachable roller brush ejection structure, enabling quick disassembly of the roller brush, and minimizing resistance when pressing down the release button.
[0004] The aforementioned application document addresses the problem of high resistance when pressing the release button and inconvenient disassembly of the roller brush in the existing quick-release roller brush structure. However, during the disassembly process of the vacuum cleaner, the vibration caused by the ejection of the floor brush roller will cause the dust adsorbed on the floor brush roller to be dispersed into the air, causing environmental pollution. Some of this dust may be inhaled by the human body, affecting health. Therefore, a new solution is needed to solve this problem. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a floor brush roller ejection structure. By setting baffle plate one and baffle plate two that are linked to the ejection component, the opening of the housing can be covered before the floor brush roller ejects, reducing the probability of dust spreading into the air when the floor brush roller ejects.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a floor brush roller ejection structure, comprising a housing and a brush roller rotatably connected within the housing, wherein fixed plates for connecting to the housing are provided at both ends of the brush roller, and a snap-fit assembly for engaging with the fixed plates is provided inside the housing, and ejection assemblies abutting against the bottom surface of the fixed plates are provided at both ends of the housing, wherein baffle plate one and baffle plate two, which can block the opening of the housing, are rotatably connected to both sides of the brush roller, and a storage groove is provided at both ends of the housing of the brush roller, wherein a drive assembly for rotating baffle plate one and baffle plate two is rotatably connected within the storage groove.
[0007] The present invention is further configured such that: the snap-fit assembly includes a snap-fit block and an elastic element; the side wall of the receiving groove is recessed inward to form a receiving groove; the two ends of the elastic element are respectively fixedly connected to the side wall of the snap-fit block and the receiving groove; and the fixing plate is provided with a snap-fit groove that can snap-fit with the snap-fit block.
[0008] The present invention is further configured such that: the pop-out component includes a push plate and several elastic elements; the inner bottom surface of the storage groove is recessed inward to form a placement groove; the two ends of the elastic elements are fixedly connected to the bottom surfaces of the push plate and the placement groove, respectively; and the push plate abuts against the bottom surface of the fixed plate.
[0009] The present invention is further configured such that: the driving assembly includes two gears rotatably connected to the inner wall of the storage groove, the two gears meshing with each other, and the two gears respectively drive the first baffle and the second baffle to rotate through two connecting rods, and each gear extends out of the housing on the side away from the fixed plate and is fixedly connected to a knob.
[0010] The present invention is further configured such that at least a portion of the locking block extends out of the locking groove, and a paddle for pushing the locking block is fixedly connected to the side of the gear near the fixing plate.
[0011] The present invention is further configured such that: the first baffle is provided with a protrusion, and the second baffle is provided with an insertion groove that cooperates with the protrusion of the first baffle; when the protrusion is fully inserted into the insertion groove, the snap-fit block separates from the snap-fit groove.
[0012] The present invention is further configured such that: the housing is provided with sliding grooves on both sides of the brush roller for receiving baffle plate one and baffle plate two, and baffle plate one and baffle plate two are slidably connected to the inner wall of the sliding groove respectively.

Detailed Implementation
[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] A type of floor brush roller ejection structure, such as Figures 1-5As shown, the device includes a housing 1 and a brush roller 2 rotatably disposed within the housing 1. Fixed plates 3 are provided at both ends of the brush roller 2 along its length for connection with the housing 1. A snap-fit assembly is provided inside the housing 1 to engage with the fixed plates 3. Pop-out assemblies are provided at both ends of the housing 1 to abut against the bottom surfaces of the fixed plates 3. When the fixed plates 3 engage with the snap-fit assemblies to assemble the brush roller 2 onto the housing 1, the fixed plates 3 compress the pop-out assemblies, causing them to retract. When the snap-fit assemblies separate from the fixed plates 3, the pop-out assemblies rebound, generating a pushing force on the fixed plates 3, thereby separating the brush roller 2 from the housing 1. Two baffle plates 4 and 5, which can block the opening of the housing 1, are rotatably connected to both sides of the brush roller 2 on the housing 1. The housing 1 also has a sliding mechanism for accommodating the baffle plates 4 and 5. The sliding groove 19 is used to store the first baffle 4 and the second baffle 5 when the vacuum cleaner is working normally. This will not affect the normal use of the vacuum cleaner, and the first baffle 4 and the second baffle 5 will not be covered with too much dust due to the use of the vacuum cleaner, so that the first baffle 4 and the second baffle 5 will not bring out a lot of dust when they are used. The housing 1 has storage grooves 6 at both ends of the brush roller 2 along its length. The storage grooves 6 are rotatably connected to the drive components for rotating the first baffle 4 and the second baffle 5. When the operator rotates the drive components, the first baffle 4 and the second baffle 5 will slide out of the sliding groove 19 and abut against each other after completing a curved path of rotation, thereby forming a protective space at the opening of the housing 1 to prevent a large amount of dust from being dispersed into the air due to vibration when the brush roller 2 is ejected.
[0023] like Figure 1 and Figure 3 As shown, the snap-fit assembly includes a snap-fit block 7 and an elastic element 8. The elastic element 8 is configured as a spring. The side wall of the receiving groove 6 is recessed inward to form a receiving groove 9. The two ends of the elastic element 8 are respectively fused to the side walls of the snap-fit block 7 and the receiving groove 9. The fixing plate 3 is provided with a snap-fit groove 10 that can snap-fit the snap-fit block 7. The cross-sectional shape of the snap-fit block 7 away from the ground is arc-shaped. When the fixing plate 3 extends into the housing 1, the fixing plate 3 will squeeze the snap-fit block 7, causing the snap-fit block 7 to move away from the fixing plate 3, and causing the elastic element 8 to be compressed. When the fixing plate 3 drives the snap-fit groove 10 to the position corresponding to the snap-fit block 7, the elastic element 8 will rebound and generate a pushing force on the snap-fit block 7, so that the snap-fit block 7 enters the snap-fit groove 10 to complete the snap-fit.
[0024] like Figures 2-5As shown, the drive assembly includes two gears 14 rotatably connected to the inner wall of the storage slot 6. The two gears 14 mesh with each other and drive baffle 4 and baffle 5 respectively through two connecting rods 15. The side of any gear 14 away from the fixed plate 3 extends out of the housing 1 and is engaged with a knob 20. The operator rotates the knob 20 to drive the meshing gear 14 to rotate. The rotation of the gear 14 is transmitted to baffle 4 and baffle 5 through the connecting rod 15, causing baffle 1 and baffle 2 to slide out of the sliding groove 19. At this time, the rotation of baffle 4 and baffle 2 5 can drive the two gears 14 located at the other end of the housing 1 to rotate synchronously through the connecting rod 15. A paddle 16 is integrally formed on the side of the gear 14 near the fixed plate 3. At least a part of the paddle 16 extends out of the engaging groove 10. The paddle 16 will rotate as the gear 14 rotates. The ejector assembly includes a push plate 11 and several elastic elements 12, which are springs. The side wall of the receiving groove 6 is recessed to form a placement groove 13. The two ends of the elastic elements 12 are fixedly connected to the bottom surfaces of the push plate 11 and the placement groove 13, respectively. Several elastic elements 12 are arranged in an array in the placement groove 13. The array of elastic elements 12 provides a stable thrust for the sliding of the push plate 11, avoiding the problem of tilting during the sliding of the push plate 11. The push plate 11 abuts against the bottom surface of the fixed plate 3. When the fixed plate 3 extends into the housing 1, it exerts pressure on the push plate 11, causing the elastic elements 12 to be compressed. When the snap-fit block 7 separates from the snap-fit groove 10, the elastic elements 12 rebound and exert a thrust on the fixed plate 3 through the push plate 11, thereby ejecting the brush roller 2 from the housing 1.
[0025] like Figures 2-5 As shown, baffle 1 4 is provided with a protrusion 17, and baffle 2 5 is provided with an insertion groove 18 that cooperates with the protrusion 17 of baffle 1 4. When the paddle 16 contacts the locking block 7, at least a part of the protrusion 17 extends into the insertion groove 18. At this time, if the knob 20 is rotated, the locking block 7 will continue to move away from the fixed plate 3 under the push of the paddle 16, and the overlapping area of the protrusion 17 and the insertion groove 18 will continue to increase. When the protrusion 17 is fully inserted into the insertion groove 18, the locking block 7 separates from the locking groove 10. The setting of the protrusion 17 and the insertion groove 18 can ensure that before the brush roller 2 pops out, baffle 1 4 and baffle 2 5 can completely cover the opening of the housing 1, and prevent the dust generated when the brush roller 2 pops out from spreading in the air.
[0026] Working principle: A brush roller ejection structure is used to assemble the brush roller 2 into the housing 1 by engaging the snap-fit block 7 in the housing 1 with the snap-fit groove 10 on the fixing plate 3. When the brush roller 2 needs to be disassembled, the operator rotates the knob 20 to rotate the gear 14. The rotation of the gear 14 is transmitted to the first baffle 4 and the second baffle 5 through the connecting rod 15, causing the first baffle 4 and the second baffle 5 to rotate out of the sliding groove 19. When at least a part of the protrusion 17 on the first baffle 4 enters the insertion on the second baffle 5... When the gear 14 is in slot 18, the paddle 16 on the gear 14 contacts the locking block 7. As the knob 20 is rotated, the paddle 16 pushes the locking block 7 to move away from the fixing plate 3. When the locking block 7 is completely separated from the locking slot 10, the protrusion 17 is fully inserted into the insertion slot 18, and the elastic element 12 rebounds and pushes the fixing plate 3 upward through the push plate 11 to eject the housing 1. At this time, the baffle 4 and the baffle 5 completely cover the opening of the housing 1 to prevent dust from spreading in the air.
