Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner device technology, and in particular to a dual-brush vacuum cleaner structure. Background Technology

[0002] Most vacuum cleaners on the market are divided into floor brushes and carpet brushes. The floor brush and carpet brush are used separately and require users to switch them manually. When cleaning carpets, use the carpet brush, and when cleaning floors, remove the carpet brush and replace it with the floor brush head. When using them interchangeably, the vacuuming performance will be greatly reduced, which will greatly affect the user experience.

[0003] In the prior art, some vacuum cleaners achieve compatibility with floors and carpets by adding a vacuum cleaner roller brush at the front. However, the fluff of the front roller brush usually greatly affects the overall vacuum level and the performance of the rear roller brush. For example, a floor brush structure with dual roller brushes is disclosed in application number 202411087753.0. It discloses that the front end of the floor brush is raised and tilted during use, which can effectively ensure the vacuum level in the suction port area and ensure the cleaning effect of the vacuum cleaner. However, its structure is relatively complex and its operation is also relatively complicated. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-brush vacuum cleaner structure. The first brush is mainly used for vacuuming, while the second brush has a good sealing effect during rotation, which can ensure the vacuum degree in the working chamber. This allows the entire dual-brush vacuum cleaner structure to be compatible with both floors and carpets, and allows larger particles to enter the working chamber for cleaning.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a dual-roller brush vacuum cleaner structure, including a body, a working chamber on the body, and a roller on one side; the dual-roller brush vacuum cleaner structure further includes:

[0006] The first roller brush is rotatably mounted inside the working chamber near the air duct opening and is connected to the drive unit.

[0007] The second roller brush is located on the side of the working chamber away from the air duct opening and is arranged side by side with the first roller brush. The lower end of the second roller brush is not higher than the lower end of the first roller brush. The second roller brush includes a positioning block, a rotating shaft, a brush body, and support wheels. The rotating shaft is rotatably disposed between a pair of positioning blocks. The brush body is sleeved on the rotating shaft. The pair of support wheels are sleeved on the rotating shaft and are respectively located on opposite sides of the brush body. The pair of positioning blocks are disposed on the machine body.

[0008] As a further optimization, the working chamber includes a first chamber body near the air duct opening and a second chamber body away from the air duct opening, with the second roller brush located in the second chamber body, which can form a better sealing effect on the first chamber body.

[0009] As a further optimization, the rotating shaft includes a main shaft, a pin, and a bearing. The pin passes through the bearing and the support wheel and extends into the main shaft. The bearing is mounted on the positioning block, and the brush body is sleeved on the main shaft.

[0010] As a further optimization, the support wheel includes a central frame and a housing. The central frame is fixed to the main shaft by the pin, and the housing is sleeved on the central frame. The positioning block is partially embedded in the central frame, which reduces the gap and improves the sealing effect on the first compartment.

[0011] As a further optimization, the body is provided with a pair of positioning slots that communicate with the working chamber, and a pair of positioning blocks are respectively embedded in the pair of positioning slots.

[0012] As a further optimization, the lower part of one of the positioning slots has an open structure.

[0013] As a further optimization, the body is provided with an auxiliary groove that communicates with the positioning groove. An insert plate is provided in the auxiliary groove, and a positioning block that matches the positioning groove is provided with a slot. The insert plate is embedded in the slot to fix the positioning block in the positioning groove.

[0014] As a further optimization, at least one of the positioning grooves and the positioning groove that matches the positioning groove are non-cylindrical structures, which can prevent the positioning block from rotating relative to the machine body and only realize the rotation of the brush body and the support wheel.

[0015] As a further optimization, the brush body is a blade-type rubber brush or a bristle brush. When the brush body is a blade-type rubber brush, its blades are arranged along the central axis parallel to the rotation axis, which can achieve the cleaning of larger particles without affecting the sealing effect.

[0016] As a further optimization, the machine body is equipped with a dust detection lamp assembly.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The first roller brush is mainly used for vacuuming. The support wheel in the second roller brush contacts the ground and rotates passively with the help of friction. Together with the roller, it supports the machine body. The brush body can sweep up dust and particles. The second roller brush has a good sealing effect during rotation, which can ensure the vacuum degree in the working chamber and ensure the vacuuming effect. This makes the entire dual roller brush vacuum cleaner structure compatible with both floors and carpets.

[0019] 2. In one embodiment, the brush body is a blade-type rubber brush or a bristle brush, which, while ensuring the sealing effect of the working chamber, allows larger particles to enter the working chamber and can complete the cleaning of larger particles. Attached Figure Description

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figures 1 to 7As shown, a dual-brush vacuum cleaner structure includes a body 10, a working chamber 100 at the lower part of the body, and a roller 11 on one side of the body 10. The dual-brush vacuum cleaner structure also includes a first roller brush 20 and a second roller brush 30. The first roller brush 20 is rotatably disposed within the working chamber 100 near the air duct opening 100a and is connected to a drive unit, which includes a motor and other structures. The second roller brush 30 is disposed within the working chamber 100 away from the air duct opening 100a and is arranged side-by-side with the first roller brush 20. The lower end of the second roller brush 30 is not higher than that of the first roller brush 20. At the lower end of brush 20, the second roller brush 30 includes positioning blocks (i.e., the first positioning block 311 and the second positioning block 312), a rotating shaft 32, a brush body 33, and a pair of support wheels 34. The rotating shaft 32 is rotatably disposed between the first positioning block 311 and the second positioning block 312. The brush body 33 is sleeved on the rotating shaft 32. The pair of support wheels 34 are sleeved on the rotating shaft 32 and are respectively located on opposite sides of the brush body 33. The first positioning block 311 and the second positioning block 312 are disposed on the machine body 10, which can realize the rotation of the brush body 33 and the pair of support wheels 34 relative to the machine body 10.

[0029] In this invention, a first roller brush 20 and a second roller brush 30 are arranged side by side. The first roller brush 20 is driven by a motor located on the body 10 and its main function is to vacuum. The support wheel 34 of the second roller brush 30 contacts the ground and rotates passively by friction, supporting the body 10 in conjunction with the roller 11. The brush body 33 can sweep away dust and particles. During operation, the second roller brush 30 has a lower position at its lower end, which provides a better sealing effect and ensures the vacuum degree in the working chamber 100, thus ensuring the vacuuming effect without affecting the performance of the first roller brush 20. This makes the entire dual roller brush vacuum cleaner structure compatible with both floors and carpets.

[0030] Preferably, the working chamber 100 includes a first chamber 101 near the air duct opening 100a and a second chamber 102 away from the air duct opening 100b. The first roller brush 20 is located inside the first chamber 101, and the second roller brush 30 is located inside the second chamber 102. By setting the second roller brush 30 inside the second chamber 102, which is more compatible with its contour structure, a better fit can be achieved, thereby ensuring a better sealing effect on the first chamber 101 located on the rear side.

[0031] Specifically, the rotating shaft 32 includes a main shaft 321, a pin 322, and a bearing 323. There are two pins 322 and two bearings 323. One of the pins 322 passes through a bearing 323 and a support wheel 34 and extends into one end of the main shaft 321. The two bearings 322 are respectively set on the first positioning block 311 and the second positioning block 312. The brush body 33 is sleeved on the main shaft 32. Through the above structure, the support wheel 34 rotates synchronously with the rotating shaft 32 relative to the first positioning block 311 and the second positioning block 312, that is, it drives the brush body 33 to rotate.

[0032] Furthermore, the support wheel 34 includes a central frame 341 and a housing 342. The central frame 341 is fixed to the main shaft 321 by a pin 322, and the housing 342 is sleeved on the central frame 341. The central frame 341 has a concave cavity structure, and at least part of the first positioning block 311 and the second positioning block 312 are embedded in the concave cavity structure of the central frame 341, which can realize the support wheel 34 wrapping the positioning blocks. When the positioning blocks are installed on the machine body 10, the gap can be reduced, and the sealing effect of the second roller brush 30 on the rear first chamber 101 can be improved.

[0033] The machine body 10 is provided with a pair of positioning grooves that communicate with the working chamber 100. Specifically, the machine body 10 is provided with a first positioning groove 121 and a second positioning groove 122 on both sides of the second chamber 102. The first positioning block 311 is embedded in the first positioning groove 121 and the second positioning block 312 is embedded in the second positioning groove 122, thereby installing the second roller brush 30 in the second chamber 102 on the machine body 10.

[0034] Preferably, the second positioning groove 122 is configured as a circular hole structure, and the second positioning block 312 that cooperates with it has a cylindrical structure. The cylindrical structure and the circular hole structure are embedded and cooperated. The lower end of the first positioning groove 121 is configured to have an open structure. After the second positioning block 312 cooperates with the second positioning groove 122, the first positioning block 311 can be inserted into the first positioning groove 121 from bottom to top through the open structure, which facilitates the installation of the second roller brush 30.

[0035] Based on the above configuration, the body 10 is provided with an auxiliary groove 122 that communicates with the first positioning groove 121. The auxiliary groove 122 includes a horizontal groove 1221 that communicates with the first positioning groove 121 and a vertical groove 1222 that communicates perpendicularly with the horizontal groove. An insert plate 35 is provided in the auxiliary groove 122 that can be slidably arranged. The insert plate 35 may have a T-shaped structure or an L-shaped structure to cooperate with the structure of the auxiliary groove 122. A slot 310 is provided on the first positioning block 311 that cooperates with the first positioning groove 121. When the first positioning block 311 is inserted into the first positioning groove 121, the slot 310 communicates with the horizontal groove 1221 of the auxiliary groove 122. When the insert plate 35 located in the auxiliary groove 122 is moved, the horizontal plate 351 on the insert plate 35 is slidably moved, extends out of the horizontal groove 1221 and extends into the slot 310 to make interference contact with the first positioning block 311. Therefore, when installing the second roller brush 30, the specific installation method is as follows: first, the second positioning block 312 at one end of the second roller brush 30 is embedded into the second positioning groove 122, and then the first positioning block 311 at the other end is inserted from bottom to top through the open structure at the lower end of the first positioning groove 121 so that the first positioning block 311 is embedded into the first positioning groove 121. Then, after the insert plate 35 is moved horizontally, its horizontal plate 351 is inserted into the slot 310 on the first positioning block 311, thereby installing the second roller brush 30 on the machine body 10. The above structure and installation method facilitate the disassembly and installation of the second roller brush 30.

[0036] Furthermore, at least one positioning groove and the positioning groove that matches the positioning groove are non-cylindrical structures. For example, the first positioning groove 121 and the first positioning block 311 both have rectangular structures. The cooperation of the rectangular structures can prevent the rotation of the first positioning block 311, so that only the brush body 33 and the support wheel 34 can rotate.

[0037] Preferably, in order to enable particles with larger diameters to enter the working chamber 100 without affecting the vacuum level within the working chamber 100, the brush body 33 is a blade-type rubber brush or a bristle brush. The blade-type rubber brush, due to the gaps between adjacent blades, allows larger diameter particles to be positioned between a pair of adjacent blades and carried into the working chamber 100. Furthermore, when the brush body 33 is a blade-type rubber brush, its blades are arranged along the central axis parallel to the rotation axis. The laterally extending and completely covering blades ensure the sealing of the second roller brush 30 to the first chamber 101. The bristle brush, due to its deformation properties, allows larger diameter particles to be deformed by squeezing the bristle brush and then pass over it to enter the working chamber 100. After the bristle brush recovers its deformation, it also ensures the sealing of the second roller brush 30 to the first chamber 101.

[0038] In addition, the body 10 is equipped with a dust indicator light group 13, which can assist in illuminating and displaying dust.

[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
