Description

Technical Field

[0001] This utility model relates to the field of cleaning brush technology, and in particular to a cleaning brush head and a cleaning brush. Background Technology

[0002] Cleaning brushes have a good cleaning effect and are frequently used in daily life for cleaning kitchens, bathrooms, toilets, cars, etc.

[0003] Existing cleaning brushes typically require manual pushing to clean items, which is cumbersome, time-consuming, and labor-intensive. Some manufacturers have improved cleaning brushes based on user needs by using electric drive, which increases cleaning efficiency. However, in electric cleaning brushes, the transmission mechanism uses a drive shaft and a shift fork to rotate the brush head for cleaning. This can create knocking noise at the connection points.

[0014] The swing element includes:

[0015] An eccentric rotating component is mounted on top of the drive shaft assembly;

[0016] The swing fitting has one end connected to the positioning sleeve and the other end movably connected to the eccentric rotating component.

[0017] This application designs a swing component that, driven by an eccentric rotating component, enables the brush assembly to rotate stably. At the same time, the eccentric rotating component and the swing component work together to reduce noise during operation.

[0018] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0019] Furthermore, the eccentric rotating member includes:

[0020] Turntable;

[0021] A rotating component is installed on the side of the turntable away from the drive shaft assembly, and the rotating component is located at the eccentricity of the turntable;

[0022] The swing fitting includes:

[0023] The oscillating disk is connected to the brush assembly;

[0024] A swing rod is installed on the swing disk, and the swing rod cooperates with the rotating component. The beneficial effect of this step is that the swing rod and the rotating rod cooperate with each other, thereby enabling the swing disk to move.

[0025] Furthermore, a mating groove is provided on one side of the turntable, and one end of the rotating component is movably disposed in the mating groove. The beneficial effect of this step is that the rotating component can move well, thereby driving the brush assembly to rotate.

[0026] Furthermore, the turntable includes:

[0028] The lower plate has a lower groove on its top side, and the lower groove and the upper groove are combined to form the mating groove;

[0029] The fixed column passes through the upper plate and connects to the lower plate. The advantage of this step is that it adopts a split structure, which allows for better setting of the mating groove, thus ensuring stable movement of the rotating parts.

[0030] Furthermore, the upper plate includes:

[0031] A horizontal section, wherein the bottom of the horizontal section is provided with the upper groove;

[0032] The vertical section cooperates with the fixed column, and the vertical section is located on the outside of the lower plate. The beneficial effect of this step is that the vertical section blocks the rotating part, so that the rotating part can be movably set in the mating groove.

[0033] Furthermore, the rotating member includes:

[0034] The transverse section has one end located inside the mating groove;

[0035] The circular segment, fitted onto the swing arm, has the beneficial effect of reducing noise during movement by cooperating with the swing arm.

[0036] Furthermore, the swing rod is installed obliquely on the swing disk, and the center line of the swing rod forms an acute angle with the upper surface of the swing disk, and the center line of the swing rod is parallel to the end face of the turntable.

[0058] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0059] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0060] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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; 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 according to the specific circumstances.

[0061] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0062] Example:

[0063] like Figure 1-5 As shown in the embodiment of this application, a cleaning brush head is disclosed for cleaning and hygiene purposes. It has an internal oscillating component, and the power source can be an electric component, which can reduce the noise when the brush head is working, and at the same time ensure the service life of the product.

[0064] like Figure 1 As shown, the specific structure of this application includes:

[0065] The housing 1 has an internal cavity 101. The shape of the housing 1 can be any existing shape. The internal cavity 101 is used to install transmission components and other parts. In order to ensure the stability of components such as the transmission shaft assembly 2, a limiting plate can also be provided. The limiting plate has corresponding grooves to limit the transmission shaft assembly 2 and ensure its stability.

[0066] The drive shaft assembly 2 is installed in the accommodating cavity 101. When in use, the drive shaft assembly 2 will cooperate with the output shaft to achieve the cleaning work of the brush head.

[0067] The swinging component 3 is installed at the end of the transmission shaft assembly 2. The swinging component 3 cooperates with the transmission shaft assembly 2 and drives the brush assembly to rotate under its drive.

[0068] The brush assembly 4 is installed on the housing 1, and one end of the brush assembly 4 extends into the accommodating cavity 101 and is connected to the swing member 3. The brush assembly 4 is an existing brush assembly, and its outer surface is provided with bristles. Under the drive of the swing member 3, it rotates to complete the cleaning work.

[0069] The innovation of this application lies in the design of the connection of the brush assembly 4, namely, the use of a swinging component, which can not only reduce energy consumption, but also reduce noise.

[0070] Specifically, such as Figure 2As shown, the swinging component 3 includes:

[0071] An eccentric rotating component 301 is mounted on the top of the drive shaft assembly 2;

[0072] The swing fitting 302 is connected at one end to the positioning sleeve of the brush assembly 4 and at the other end to the eccentric rotating part 301. This application adopts a movable connection to realize the transmission of power, which can reduce noise.

[0073] In one embodiment, such as Figure 3 , 4 As shown, the eccentric rotating member 301 includes:

[0074] Turntable 303;

[0075] Rotating component 304 is installed on the side of the turntable 303 away from the transmission shaft assembly 2, and the rotating component 304 is located at the eccentric position of the turntable 303. The eccentric rotating component 301 of this application includes two parts, namely, the turntable 303 rotates under the drive of the driving component, and the rotating component 304 is located at the eccentric position, which facilitates the movement of the subsequent swinging mating component.

[0076] The swing fitting 302 includes:

[0077] The oscillating disk 305 is connected to the brush disk assembly 4;

[0078] The swing rod 306 is installed on the swing disk 305, and the swing rod 306 cooperates with the rotating component 304. That is, the swing rod 306 is driven by the rotating component 304 to move, thereby driving the swing disk to rotate counterclockwise or clockwise.

[0079] The turntable 303 has a mating groove 309 on one side, and one end of the rotating member 304 is movably disposed in the mating groove 309. That is, there is a gap between the bottom of the mating groove 309 and the end of the rotating member 304, so that the rotating member 304 has enough space to extend and retract when it moves with the turntable 303.

[0080] The turntable 303 can be a single molded part or composed of multiple parts assembled together. In one embodiment, such as... Figure 2As shown, the turntable 303 is assembled from an upper plate 307 and a lower plate 308. During assembly, a mating groove is left inside for installing the end of the rotating component 304. One end of the rotating component 304 is located inside the mating groove. After the upper plate 307 and the lower plate 308 are assembled, stability can be further guaranteed. At the same time, the inner wall of the mating groove is stepped, and the end of the rotating component 304 is also stepped. That is, the end of the rotating component 304 located inside the mating groove is larger in size. Similarly, the mating groove is also larger inside and smaller outside. This can prevent the rotating component 304 from detaching from the mating groove.

[0081] The structure of the turntable 303 in this application will be further described, wherein the turntable 303 includes:

[0082] The upper plate 307 has an upper groove 310 on its bottom side;

[0083] The lower plate 308 has a lower groove 311 on its top side, and the lower groove 311 and the upper groove 310 are combined to form the mating groove 309;

[0084] The fixing post 312 passes through the upper plate 307 and connects to the lower plate 308. Preferably, there are at least two fixing posts 312 to ensure the stable assembly of the upper plate 307 and the lower plate 308.

[0085] Specifically, the upper plate 307 includes:

[0086] The horizontal segment 313 has the upper groove 310 formed at its bottom;

[0087] The vertical section 314 cooperates with the fixed column 312, and the vertical section 314 is located outside the lower plate 308; this application uses the vertical section 314 to block the end of the mating groove 309 to prevent the rotating part 304 from disengaging.

[0088] In one embodiment, the rotating member 304 can be a one-piece molded part or two parts fixed together. It includes a transverse section 315 and an annular section 316. The annular section 316 of the rotating member 304 is fitted onto the swing rod 306. In this way, the rotating member 304 and the swing rod 306 can cooperate with each other to form a movable part, thereby enabling the swing disk 305 to swing. A part of the transverse section 315 is located inside the mating groove 309, that is, a part of the transverse section is stepped and cooperates with the mating groove 309.

[0089] To ensure that the swing disk 305 can swing more effectively, the swing rod 306 is installed obliquely on the swing disk 305, and the center line of the swing rod 306 forms an acute angle with the upper surface of the swing disk 305. At the same time, the end face of the swing rod 306 and the turntable 303 are parallel.

[0090] In order to extend the service life of the corresponding components and better reduce noise during use, this application designs the materials of the corresponding components. Specifically, the turntable 303, rotating component 304, swing disk 305 and swing rod 306 are all metal parts.

[0091] The drive shaft assembly 2 can be an existing component, or it can be a drive shaft assembly 2 with the following structure:

[0092] The connector sleeve 201 is installed inside the accommodating cavity 101;

[0093] The drive shaft 202 has an end that mates with the connector sleeve 201.

[0094] The transmission shaft sleeve 203 is fitted onto the transmission shaft 202. The corresponding components cooperate with each other and connect with the driving component to complete the transmission.

[0095] Further explanation is provided regarding the disk flushing component in this application: (e.g.) Figure 5 As shown, the disk brushing component 4 can be an existing disk brushing component, or it can have the following structure, including:

[0096] The brush disk 401 has extending protrusions 402 on both sides above it. A portion of the brush disk 401 is located outside the housing 1, and the other end extends into the accommodating cavity 101. Similarly, the extending protrusions 402 are located inside the accommodating cavity 101.

[0097] Brush shaft 403 is installed in the middle of brush 401;

[0098] A positioning sleeve 404 is sleeved on the brush shaft 403, and the positioning sleeve 404 has a slot 405 that cooperates with the extension boss 402.

[0099] This application designs a brush assembly, specifically a positioning sleeve, which connects to the swing disk 305 to facilitate subsequent interaction with the swing rod 306, thereby achieving rotation.

[0100] Additionally, this application may provide a gasket on the extension boss 402 to ensure that the extension boss 402 and the slot 405 cooperate.

[0101] Noise testing was conducted on this application:

[0102] Place the cleaning brush in the noise box, measure the straight-line distance (horizontal and vertical) between the cleaning brush head and the sound meter (30 cm), turn on the cleaning brush, turn off the noise box, record the noise value on the sound meter for 1 minute (record once every 10 seconds), calculate the average value, and finally find that it is only 60-75 dB, which can reduce the noise by at least 5-10 dB.

[0103] This application also discloses a cleaning brush, including the aforementioned cleaning brush head.

[0104] The specific work process for this application is as follows:

[0105] The drive assembly drives the transmission shaft assembly 2 to move. When the transmission shaft assembly 2 rotates, it drives the turntable 303 to rotate. At this time, the rotating part 304 is in an eccentric position and also rotates. The swing rod 306 can swing under the drive of the rotating part 304, thereby driving the brush plate 401 to swing, thus completing the cleaning work.

[0106] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
