Example 1

Referring to fig. 1 and 2, the present embodiment provides a rolling brush 100, which includes a first suction opening 20, a second suction opening 22, and a rolling brush body 24 disposed between the first suction opening 20 and the second suction opening 22, and an airflow sequentially passes through the first suction opening 20, the rolling brush body 24, and the second suction opening 22 and enters into a vacuum cleaner, so as to suck the airflow containing dust into the vacuum cleaner, thereby achieving the purpose of cleaning.

Specifically, the rolling brush 100 includes a housing 26 for accommodating the rolling brush body 24, a bottom plate 28 is disposed or connected to a bottom of the housing 26, and the first suction port 20 is disposed through the bottom plate 28. The side of the roller brush 100 remote from the first suction opening 20 is provided with a tubular member 30, the tubular member 30 being adapted to be connected to a vacuum cleaner, and the housing 26 is therefore also provided with a second suction opening 22 therein which communicates with the distal outlet of the tubular member 30. The roller brush body 24 is in airflow communication with the first suction opening 20 and the second suction opening 22, i.e. an airflow can enter from the first suction opening 20, flow through the roller brush body 24 and enter the second suction opening 22.

When the roller brush 100 is in operation, the bottom plate 28 contacts the surface to be cleaned, the roller brush body 24 rotates to stir dust off the surface to be cleaned, the vacuum cleaner connected to the roller brush 100 generates a negative pressure, the negative pressure causes the first suction opening 20 to suck dust and air flow (dusty air flow) agitated by the roller brush 100 into the vacuum cleaner, and then the dusty air flow passes through the roller brush body 24 and the second suction opening 22 in sequence and finally enters the filter device of the vacuum cleaner, and the filter device collects the dust therein and discharges clean air out of the vacuum cleaner, so that the purpose of cleaning is achieved.

Referring to fig. 3 and 4, the rolling brush body 24 includes a main body 32 and a cleaning element 34, the main body 32 is provided with a mounting portion 36, and the cleaning element 34 is mounted on the mounting portion 36. Each part is simple to manufacture and convenient to install.

Specifically, the main body 32 extends lengthwise and is substantially cylindrical, the outer peripheral surface of the main body 32 is provided with a mounting portion 36, the end portion of the main body 32 can be connected with a driving device to be driven and rotated, and the cleaning piece 34 is driven to rotate when the main body 32 is driven and rotated to realize cleaning.

The number of the mounting portions 36 is at least two, and the at least two mounting portions 36 are evenly spaced on the body 32. The number of the cleaning pieces 34 corresponds to the number of the mounting portions 36, and at least two cleaning pieces 34 are uniformly provided on the body 32. Therefore, in the process that the body 32 rotates for one circle, at least two cleaning pieces 34 beat the ground in turn, and the cleaning efficiency is improved.

The mounting portion 36 includes a middle section 38 and two end side sections 40, the middle section 38 extends spirally along the circumference of the body 32, and an included angle formed at the intersection of at least one of the end side sections 40 and the middle section 38 is an obtuse angle. In the present embodiment, one of the two end sections 40 forms an obtuse angle with the middle section 38, but those skilled in the art can also appreciate that the two end sections 40 form an obtuse angle with the middle section 38.

During the rotation of the rolling brush body 24, the cleaning element 34 rotates to clean dust, hairs may be present in the dust, and when the hairs rotate along with the cleaning element 34, the hairs are easily wound around the rolling brush body 24, and particularly easily reach the end of the rolling brush body 24 along with the inertia of the rotation of the rolling brush body 24, and as time goes on, the hairs at the end are accumulated more, which is not only difficult to clean, but also greatly affects the working efficiency of the rolling brush body 24.

In this embodiment, the junction between the end side segment 40 and the middle segment 38 forms an obtuse angle, so that when the hairs rotate with the roller brush 100 to reach the junction from the middle segment 38, the junction not only interrupts the tendency of the hairs to continue sliding toward the ends; moreover, because the included angle between the end side section 40 and the middle section 38 is an obtuse angle, and the directions of the two sections are different, when the rolling brush body 24 rotates, the pushing action of the end side section 40 and the middle section 38 on the hair is opposite, and after the hair reaches the end side section 40 from the middle section 38, the end side section 40 pushes the hair towards the middle section 38 along with the continuous rotation of the rolling brush body 24, so that the hair is prevented from being intensively wound on the end side section 40 of the rolling brush body 24. That is, during the rotation of the rolling brush body 24, the inertial force generated by the rotation of the middle segment 38 pushes the hair toward the end segment 40, and the inertial force generated by the rotation of the end segment 40 pushes the hair toward the middle segment 38, so that the acting forces of the two are offset, and the hair is not easily wound on the rolling brush body 24, but is easily thrown off by the rolling brush body 24, thereby preventing the hair from being wound. Through experimental tests, the design has excellent anti-tangling effect, but has very simple structure and very ingenious design.

As previously mentioned, there are at least two mounting portions 36, defining a number N of mounting portions 36, and the intermediate section 38 has a circumferential extent equal to 360/N. For example, if the number of mounting portions 36 is two, the circumferential extension angle of each mid-section 38 is 180 °; if the number of mounting portions 36 is three, the circumferential extension angle of each intermediate section 38 is 120 °. With this arrangement, the middle sections 38 of the at least two mounting portions 36 are distributed in the entire circumferential direction of the body 32, so that the layout is neat, and the cleaning efficiency of the cleaning elements 34 mounted on the mounting portions 36 can be improved.

Returning to figure 2, as previously described, the airflow enters the cleaner sequentially through the first suction opening 20, the rolling brush body 24 and the second suction opening 22. Preferably, the first suction opening 20, the second suction opening 22 and the rolling brush body 24 extend in the same direction, the extension length of the first suction opening 20 is greater than that of the second suction opening 22, the extension length of the main body 32 is greater than or equal to that of the first suction opening 20, and the middle section 38 includes an area where the rolling brush body 24 and the second suction opening 22 overlap in the extension direction.

The first suction opening 20 is a suction opening of the entire roll brush 100, and the extension length of the body 32 is greater than that of the first suction opening 20, so that the roll brush 100 can be ensured to play a role in cleaning dust near the position of the first suction opening 20, and the cleaning efficiency is improved. As described above, the end side section 40 forms an obtuse angle with the middle section 38, the extension length of the second suction port 22 is less than the extension length of the first suction port 20, the middle section 38 includes the region where the rolling brush body 24 and the second suction port 22 overlap in the extension direction, the end side section 40 is located outside the region of the second suction port 22, from the viewpoint of the airflow, the end side section 40 will provide a blocking effect to the airflow flowing along the middle section 38, which will prevent the hair from winding around the end side section 40, but will also bring a certain noise, and the airflow flow outside the region of the second suction port 22 is lower than the airflow flow inside the region of the second suction port 22, so that when the end side section 40 is located outside the region of the second suction port 22, the noise can be greatly reduced relatively. In conclusion, the rolling brush body 24 of the embodiment has the advantages of good anti-tangling effect, low working noise, reasonable design and great improvement on user experience.

Referring to fig. 3 and 4, the body 32 is integrally formed, and the mounting portion 36 is a mounting groove integrally formed on the body 32. Alternatively, the mounting groove is formed depressed inward from the outer surface of the body 32. The cleaning element 34 can be mounted by inserting it into the mounting portion 36. The main body 32 and the mounting portion 36 are easily manufactured, and the mounting operation of the cleaning implement 34 is also simplified.

The mounting groove includes an inner groove 42 and an outer groove 44 which are communicated with each other in the radial direction, the width of the inner groove 42 is larger than that of the outer groove 44, and specifically, the cross section of the mounting groove is approximately T-shaped from inside to outside in the radial direction. The cleaning element 34 comprises a mounting area 46 and a working area 48, the mounting area 46 is mounted in the mounting groove, and the shape of the mounting area 46 matches the shape of the mounting groove. Because the mounting groove is wide inside and narrow outside, after the cleaning piece 34 is mounted, the shape of the mounting groove can avoid the cleaning piece 34 from falling off, and the structural design is reasonable.

The middle section 38 of the mounting groove is communicated with the end side section 40, so that the cleaning piece 34 is convenient to mount, and the whole rolling brush body 24 is simple in structure and convenient to mount.

In particular, the mounting groove formed by the communication of the middle section 38 and the end section 40 extends over the entire extension of the body 32, i.e. the two end faces of the mounting groove are flush with the two end faces of the body 32. Preferably, the cleaning member 34 is integrally formed and mounted to the mounting groove. This makes the cleaning implement 34 very simple to manufacture and install. Specifically, when the cleaning piece 34 is installed, the installation area 46 of the cleaning piece 34 can be inserted into the installation groove from one end face, and the working area 48 of the cleaning piece 34 can be pulled until the installation area 46 of the cleaning piece 34 is completely installed in the whole installation groove, so that the structure design is reasonable, and the installation is very convenient.

As mentioned above, the mounting portion 36 includes the middle section 38 and the end side section 40, the obtuse angle formed between the middle section 38 and the end side section 40 can prevent the entanglement of the bristles, and after the cleaning element 34 is mounted in the mounting groove, the cleaning element 34 also includes two obtuse angle sections, which can further prevent the entanglement of the bristles, and the principle will not be described again.

As previously described, the sweeper 34 includes a mounting area 46 and a working area 48. Preferably, the working area 48 is sheet-like. The sheet-like working area 48 has no macroscopic gaps, and no hairs are caught in the gaps, which further prevents tangling.

The cleaning element 34 is integrally molded from a material having elasticity such as rubber, for example, integrally molded from polyurethane, and is not only simple to manufacture but also effective in preventing entanglement and having wear resistance.

Referring to fig. 5, on a plane perpendicular to the extending direction of the body 32, the projection of the cleaning member 34 forms a ring shape and encloses the projection of the body 32. That is, when viewed from the side, the projection of the cleaning element 34 on the plane perpendicular to the extending direction of the body 32 has no gap, so that the cleaning element 34 can be in continuous contact with the ground surface without interruption when rotating, and the impact and noise generated when the rolling brush 100 works can be greatly reduced.

Referring to fig. 6, the roller brush 100 is provided with a retainer ring 50 at a position adjacent to the end side of the body 32, and the inner diameter of the retainer ring 50 is larger than the outer diameter of the body 32 and smaller than the outer diameter of the cleaning member 34. Thus, the cleaning element 34 is radially engaged between the inner wall surface of the retainer ring 50 and the body 32, and there is no gap between the cleaning element 34 and the retainer ring 50 in the radial direction, so that the hairs cannot enter the retainer ring 50, and the hairs are further prevented from moving to the end portion and being intensively wound around the end portion.

The cleaning element 34 has certain elasticity, and the cleaning element 34 is in interference fit with the retainer ring 50. Thus, the retainer ring 50 does not interfere with the rotational cleaning of the cleaning element 34, and also prevents hairs from moving toward the end portion and being entangled around the end portion, and the structure is simple and smart.

The angle formed by the cleaning element 34 and the abutment of the retainer ring 50 is obtuse. The obtuse angle formed by the contact between the cleaning element 34 and the retainer ring 50, which is similar to the obtuse angle formed by the middle section 38 and the end section 40 of the mounting portion 36, also reduces the tendency of the cleaning element 34 to guide hairs to the end portion during rotation, thereby reducing the probability of the hair tangling at the end portion.

In summary, the middle section 38 and the end section 40 of the mounting portion 36 of the rolling brush body 24 of the present embodiment form an obtuse angle, so as to reduce the entanglement of bristles; the middle section and the end side section of the cleaning piece 34 form an obtuse angle, so that the hair winding is reduced; the cleaning element 34 and the retainer ring 50 are in an obtuse angle, so that the entanglement of the bristles is reduced. Therefore, the rolling brush 100 of the present embodiment reduces the probability of hair tangling from a plurality of design angles, and experiments prove that the anti-hair-tangling effect is excellent, but the structure of the whole rolling brush body 24 is very simple, and can be changed slightly, with great effect and skillful design. Moreover, the rolling brush body 24 of the present embodiment has low noise and is excellent in user experience.
