Description

Technical Field

[0001] This utility model relates to the field of cleaning electrical appliances, and in particular to vacuum cleaners. Background Technology

[0002] A vacuum cleaner works by using a motor to drive a roller brush and a fan impeller to rotate. The roller brush contacts the ground or object surface, and its rotation gathers dust, hair, debris, and other trash. Then, the negative pressure generated by the rotating fan impeller draws the dust and trash gathered by the roller brush into the vacuum cleaner's chamber.

[0003] Because the roller brush needs to rotate at high speed, and both ends of the brush are fixed to the outer casing, the sides of the brush cannot fully conform to the wall, leaving blind spots that cannot be cleaned. This means the vacuum cleaner cannot clean the entire room independently, requiring the use of other cleaning equipment. This increases the time and effort required to clean the entire room, reducing cleaning efficiency. Furthermore, using multiple cleaning devices increases household expenses and takes up more storage space.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a vacuum cleaner to improve its cleaning ability.

[0006] The technical solution of this utility model is as follows:

[0007] A vacuum cleaner includes a floor brush housing, an air duct, a main roller brush, and side roller brushes;

[0008] The air duct is connected to the floor brush housing, and a fan is connected to the air duct;

[0009] The main roller brush is rotatably disposed inside the floor brush housing; the main roller brush is arranged laterally and connected to the first motor; the bristles of the main roller brush extend from the lower part of the floor brush housing;

[0010] The side roller brush is rotatably disposed within the floor brush housing; the side roller brush is horizontally disposed and connected to the second motor; the side roller brush is perpendicular to the main roller brush; the side roller brush is disposed at the end of the main roller brush;

[0011] The first motor drives the main roller brush to rotate, and the bristles of the main roller brush extending out of the floor brush housing rotate toward one side of the air duct; the second motor drives the side roller brush to rotate, and the bristles of the side roller brush extending out of the floor brush housing rotate toward one side of the main roller brush.

[0012] A further technical solution is that the diameter of the side roller brush is smaller than the diameter of the main roller brush.

[0013] A further technical solution is that the bristles of the side roller brush extend from both the bottom surface and the vertical side surface of the floor brush housing.

[0014] A further technical solution is that a side roller brush is provided at each end of the main roller brush.

[0015] A further technical solution is that, along the length direction of the side roller brush, at least three rows of bristles are arranged circumferentially on the side roller brush.

[0016] A further technical solution is that the side roller brush is connected to the floor brush housing via a rotating shaft; the side roller brush is also provided with tooth grooves, and the output shaft of the second motor is provided with teeth that mesh with the tooth grooves.

[0017] A further technical solution is that the floor brush housing includes an upper cover and a lower cover; a transparent cover is detachably provided on the upper cover.

[0018] A further technical solution is that a soft bristle strip is provided on the lower surface of the floor brush housing; the soft bristle strip is provided on the side of the main roller brush near the air duct.

[0019] A further technical solution is that a pressure block is also provided inside the floor brush housing; the pressure block is threadedly connected to the floor brush housing; and the second motor is disposed between the pressure block and the floor brush housing.

[0020] A further technical solution is that the outer shell of the floor brush is hinged with a connecting sleeve; the connecting sleeve is fitted onto the air duct.

[0021] The beneficial technical effects of this utility model are as follows:

[0022] (1) The vacuum cleaner of this utility model is equipped with a main roller brush and an air duct. The main roller brush gathers dust and debris, and then sucks the debris away along the air duct, efficiently completing the cleaning. Simultaneously, a side roller brush is also provided. The side roller brush is located at the end of the main roller brush, and the side roller brush is perpendicular to the main roller brush. During cleaning, the side roller brush rotates, sweeping the dust and debris it comes into contact with towards the main roller brush. That is, when the end of the main roller brush is against the wall, the side roller brush is located between the wall and the main roller brush. At this time, the side roller brush can gather the dust and debris between the wall and the main roller brush towards the main roller brush, completing the cleaning of the floor between the wall and the main roller brush. The side roller brush greatly reduces the cleaning dead angles of the vacuum cleaner, allowing the vacuum cleaner to easily reach and clean the dead angles that the main roller brush cannot reach, thereby improving the overall cleaning efficiency.

[0023] (2) Furthermore, the diameter of the side roller brush is smaller than that of the main roller brush. The smaller the diameter of the side roller brush, the smaller the dead angle between the side roller brush on the outer surface of the cylinder and the corner of the wall, further reducing the cleaning dead angle of the vacuum cleaner and improving the cleaning efficiency of the vacuum cleaner. At the same time, the smaller diameter of the side roller brush can also effectively reduce the volume of the entire floor brush shell of the vacuum cleaner, allowing the vacuum cleaner to enter a smaller space for cleaning.

[0024] (3) Furthermore, the bristles of the side roller brush extend from both the bottom and vertical sides of the floor brush housing. This allows the side roller brush to make contact with the ground as much as possible, reducing the cleaning dead spots of the vacuum cleaner. Attached Figure Description

[0033] Figure 1 An exploded structural diagram of the vacuum cleaner of this utility model is shown. Figure 2 A bottom view of the vacuum cleaner of this utility model is shown. Figure 3 This image shows a partial enlarged view of the vacuum cleaner of this invention at point A. Please refer to it. Figure 1 , Figure 2 and Figure 3 The vacuum cleaner includes a floor brush housing 2, an air duct 3, a main roller brush 4, and side roller brushes 5. The air duct 3 connects to the floor brush housing 2 and is connected to a fan. An air inlet cover 31 is provided at the inlet of the air duct 3, and the air inlet cover 31 is threaded onto the floor brush housing 2. The main roller brush 4 is rotatably mounted inside the floor brush housing 2. The main roller brush 4 is horizontally positioned and connected to a first motor 41. The bristles 6 of the main roller brush 4 extend from the lower part of the floor brush housing 2. Dust and debris are gathered by the main roller brush 4 and then sucked away along the air duct 3, efficiently completing the cleaning. The side roller brush 5 is rotatably mounted inside the floor brush housing 2. The side roller brush 5 is horizontally positioned and connected to a second motor 7. The side roller brush 5 is perpendicular to the main roller brush 4. The side roller brush 5 is located at the end of the main roller brush 4. The first motor 41 drives the main roller brush 4 to rotate, and the bristles 6 of the main roller brush 4 extending from the floor brush housing 2 rotate towards one side of the air duct 3. The second motor 7 drives the side roller brush 5 to rotate, and the bristles 6 of the side roller brush 5 extend from the floor brush housing 2 and rotate towards one side of the main roller brush 4. During cleaning, the side roller brush 5 rotates, sweeping the dust and debris it comes into contact with towards the main roller brush 4. That is, when the end of the main roller brush 4 is in contact with the wall, the side roller brush 5 is located between the wall and the main roller brush 4. At this time, the side roller brush 5 can gather the dust and debris between the wall and the main roller brush 4 towards the main roller brush 4, completing the cleaning of the floor between the wall and the main roller brush 4. The design of the side roller brush 5 greatly reduces the cleaning dead angles of the vacuum cleaner, allowing the vacuum cleaner to easily reach and clean the dead angles that the main roller brush 4 cannot reach, thereby improving the overall cleaning efficiency.

[0034] In some embodiments, the first motor 41 is connected to the main roller brush 4 via a transmission mechanism. The transmission mechanism can be a gear drive or a belt drive. The mechanical energy of the first motor 41 is transmitted to the main roller brush 4 via the transmission mechanism. The transmission mechanism allows for easy adjustment of the motor's power output, ensuring that the main roller brush 4 receives appropriate torque and speed, thereby guaranteeing the vacuum cleaner's cleaning efficiency. A control module is also provided inside the floor brush housing 2. This control module controls and outputs current to control the first motor 41 and the second motor 7, driving the main roller brush 4 and the side roller brush 5 to rotate for cleaning.

[0035] Please refer to Figure 1 and Figure 2 The diameter of the side roller brush 5 is smaller than that of the main roller brush 4. The smaller the diameter of the side roller brush 5, the smaller the dead angle between the side roller brush 5 on the outer surface of the cylinder and the corner of the wall, further reducing the cleaning dead angle of the vacuum cleaner and improving the cleaning efficiency of the vacuum cleaner. At the same time, the smaller diameter of the side roller brush 5 can also effectively reduce the volume of the entire floor brush shell 2 of the vacuum cleaner, allowing the vacuum cleaner to enter smaller spaces for cleaning.

[0036] In this embodiment, the bristles 6 of the side roller brush 5 extend from both the bottom surface and the vertical side of the floor brush housing 2. This allows the side roller brush 5 to contact the ground as much as possible, reducing the cleaning dead zones of the vacuum cleaner. Specifically, the bristles 6 of the side roller brush 5 preferably extend 2-3mm from the floor brush housing 2, so that the bristles 6 can contact the surface to be cleaned and simultaneously reach into the tiny crevices of the surface to be cleaned, in order to clean uneven surfaces.

[0037] Preferably, a side roller brush 5 is provided at each end of the main roller brush 4. The two side roller brushes 5 work together to clean the dead corners at both ends of the main roller brush 4, further reducing the cleaning dead corners of the vacuum cleaner and increasing the cleaning area of ​​the vacuum cleaner.

[0038] Figure 4 This image shows a partial enlarged view of the vacuum cleaner of this invention at point B. Please refer to the image. Figure 1 and Figure 4 Along the length of the side roller brush 5, at least three rows of bristles 6 are arranged circumferentially. When the side roller brush 5 rotates, the three or more rows of bristles 6 can form a continuous cleaning trajectory, ensuring that the target surface is cleaned sufficiently with each revolution of the side roller brush 5. If the number of rows of bristles 6 is small, the side roller brush 5 needs to have a higher rotation speed to maintain sufficient cleaning frequency of the bristles 6 on the target surface, which places higher demands on the performance of the second motor 7, thus increasing the cost.

[0039] In this embodiment, the side roller brush 5 is rotatably connected to the floor brush housing 2 via a rotating shaft 52. Specifically, the rotating shaft 52 and the side roller brush 5 can be connected by a key, or the rotating shaft 52 and the floor brush housing 2 can be connected by a bearing. The side roller brush 5 is also provided with a toothed groove 51, and the output shaft of the second motor 7 is provided with teeth 71 that mesh with the toothed groove 51. In some embodiments, the output shaft of the second motor 7 and the side roller brush 5 can be connected by a key.

[0040] Preferably, a pressure block 24 is also provided inside the floor brush housing 2. The pressure block 24 is threadedly connected to the floor brush housing 2. The second motor 7 is disposed between the pressure block 24 and the floor brush housing 2. The position of the second motor 7 is fixed by the pressure block 24. The pressure block 24 and the floor brush housing 2 can be connected by threaded fasteners for easy disassembly.

[0041] Please refer to Figure 1 and Figure 2 The floor brush housing 2 includes an upper cover 21 and a lower cover 22. A transparent cover 211 is detachably provided on the upper cover 21. The transparent cover 211 allows the operator to easily observe the inside of the floor brush housing 2, facilitating the maintenance of the vacuum cleaner.

[0042] Preferably, a soft bristle strip 23 is provided on the lower surface of the floor brush housing 2. The soft bristle strip 23 is located on the side of the main roller brush 4 near the air duct 3. The soft bristle strip 23 can adhere to and absorb dust and debris, preventing the dust and debris gathered by the main roller brush 4 from being thrown out.

[0043] More preferably, the floor brush housing 2 is hinged with a connecting sleeve 1. The connecting sleeve 1 is fitted onto the air duct 3. The connecting sleeve 1 protects the air duct 3. At the same time, the connecting sleeve 1 connects the vacuum cleaner to the vacuum cleaner handle.

[0044] The specific workflow of this utility model is as follows:

[0045] When cleaning, the user first starts the first motor 41, the second motor 7, and the fan connected to the air duct 3. Then, the user moves the floor brush housing 2, causing the main roller brush 4 and the side roller brush 5 to move along the surface to be cleaned. During this movement, the main roller brush 4 continuously rotates, sweeping away dust and debris it encounters and gathering them towards the entrance of the air duct 3. Simultaneously, the side roller brush 5 continues to rotate, sweeping away dust and debris it encounters and gathering them towards the main roller brush 4, which then gathers them towards the entrance of the air duct 3. At this time, under the action of the fan, a negative pressure space is formed inside the air duct 3. The dust and debris gathered by the main roller brush 4 are sucked into the air duct 3 and then thrown into the vacuum cleaner's cavity. The user continues to move the vacuum cleaner to complete the cleaning of the target area.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
