Description

Technical Field

[0001] This utility model relates to the field of detergent brush head technology, specifically a detergent brush head assembly. Background Technology

[0002] In daily life and industrial production, dishwashers, as efficient cleaning tools, are widely used for cleaning stains in scenarios such as home kitchens, bathrooms, vehicle surfaces, and industrial equipment shells. The brush head assembly, as the core component of the dishwasher that directly contacts the surface to be cleaned, directly determines the cleaning efficiency, user experience, and applicability of the dishwasher through its structural design, cleaning performance, and adaptability. It is one of the key indicators for measuring the competitiveness of a dishwasher product.

[0003] Currently, most mainstream dishwasher brush head assemblies on the market use a traditional bolt-fixed connection structure to connect to the rotating shaft of the dishwasher. With this type of connection, replacement requires users to first use specific tools (such as screwdrivers and Allen wrenches) to loosen and remove each bolt securing the brush head to the rotating shaft. After removing the old brush head, the new brush head is aligned with the rotating shaft, and the bolts are tightened again. If the user forgets to bring or loses the necessary tools, brush head replacement cannot be completed. During cleaning, wastewater, oil, dust, and detergent residue easily adhere to the bolts and bolt holes. Over time, these impurities can solidify and clump at the bolt threads, or cause corrosion in humid environments, resulting in a tight fit between the bolts and threads, making them difficult to loosen. Utility Model Content

[0004] The purpose of this utility model is to provide a washing machine brush head assembly, which uses a sleeve with a first sliding groove, a second sliding groove and a limiting groove inside, and a rotating shaft is directly inserted into the sleeve to make the limiting post lock in the limiting groove, so as to achieve quick installation and disassembly.

[0005] To address the problems of existing technologies, this utility model provides a washer brush head assembly, characterized by comprising a brush head support member capable of being mounted on a washer; a rotating shaft mounted on a drive device on the washer for rotating the brush head support member; a sleeve is provided at the center of the top of the brush head support member, the inner wall of the sleeve has several vertically arranged first sliding grooves, the inner wall of the sleeve also has horizontally arranged second sliding grooves connected to the first sliding grooves, the inside of the sleeve also has vertically upward limiting grooves connected to the second sliding grooves, and the rotating shaft has several limiting posts corresponding to the first sliding grooves, the limiting posts being able to move in the first and second sliding grooves and be engaged in the limiting grooves.

[0006] Preferably, a spring is provided inside the sleeve, and a push plate is fixedly connected to the top of the spring. The push plate can contact the rotating shaft and cause the limiting post on the rotating shaft to be locked in the limiting groove.

[0007] Preferably, the bottom of the brush head support is provided with a detachable brush head unit, the brush head unit including a support plate and a plurality of bristle bundles disposed at the bottom of the support plate.

[0008] Preferably, a second magnet is provided at the center of the top of the support plate, and a support groove that cooperates with the second magnet is provided at the center of the bottom of the brush head support. A first magnet is fixed in the support groove. When the second magnet is inserted into the support groove, the first magnet can attract the second magnet.

[0009] Preferably, a plurality of guide rails are vertically arranged on the inner wall of the bottom of the brush head support, and guide grooves corresponding to the guide rails are opened around the support plate.

[0010] Preferably, the support groove and the second magnet are hexagonal.

[0011] Preferably, both the brush head support and the support plate are made of plastic.

[0012] The advantages of this application compared to the prior art are:

[0013] The washer brush head assembly proposed in this application constructs an efficient quick-installation connection structure by integrating a sleeve at the top of the brush head support and pre-setting a first sliding groove, a second sliding groove, and a limiting groove on the inner wall of the sleeve. During the assembly process of the brush head assembly and the washer main unit, after the rotating shaft on the main unit is inserted into the sleeve along the axial direction of the sleeve, the limiting post set on the outer wall of the rotating shaft first slides along the extension direction of the first sliding groove until it reaches the bottom limiting position of the first sliding groove. At this time, by rotating the brush head support around the axial direction of the rotating shaft, the sleeve is driven to rotate synchronously, so that the limiting post transitions from the bottom of the first sliding groove to the starting end of the second sliding groove, and continues to slide along the preset trajectory of the second sliding groove. When the limiting post slides to the end of the second sliding groove, the limiting post further engages in the limiting groove, completing the quick installation and positioning of the brush head assembly and the rotating shaft, and realizing the quick installation of the brush head assembly. To ensure the stability of the connection structure, this application incorporates a spring and a push plate inside the brush head assembly. The spring is in a pre-compressed state, and its elastic force continuously acts on the push plate, which in turn applies an axial preload to the rotating shaft. This effectively prevents the limiting post from dislodging from the limiting groove, thus ensuring that the brush head assembly maintains a stable connection during cleaning operations. Furthermore, the brush head unit and brush head support in this application adopt a detachable connection design. This design allows users to individually disassemble and replace the brush head unit according to the needs of different cleaning scenarios without adjusting the brush head support and sleeve connection structures. This expands the applicability of the brush head assembly, reduces user costs, and enhances the overall practicality and flexibility of the brush head assembly. Attached Figure Description

Detailed Implementation

[0020] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0021] Reference Figures 1-5 As shown, this utility model provides a washer brush head assembly, including a brush head support 1, which can be installed on a washer; a rotating shaft 3, mounted on a drive device on the washer, for rotating the brush head support 1; a sleeve 14 is provided at the center of the top of the brush head support 1, the inner wall of the sleeve 14 has several vertically arranged first sliding grooves 141, the inner wall of the sleeve 14 also has horizontally arranged second sliding grooves 142 connected to the first sliding grooves 141, and the inside of the sleeve 14 also has a vertically upward limiting groove 143 connected to the second sliding groove 142; the rotating shaft 3... The upper part is provided with several limiting posts 31 corresponding to the first slide groove 141. The limiting posts 31 can move in the first slide groove 141 and the second slide groove 142 and be locked in the limiting groove 143. The sleeve 14 provides an insertion channel for the rotating shaft 3. The rotating shaft 3 is guided to be inserted along the preset axis through the central hole structure to ensure the alignment of the two during assembly. Furthermore, the first slide groove 141, the second slide groove 142 and the limiting groove 143 opened on the inner wall provide a moving trajectory and positioning space for the limiting posts 31 on the rotating shaft 3, so as to realize the quick engagement and fixation of the brush head support 1 and the rotating shaft 3.

[0022] Align the sleeve 14 at the top of the brush head support 1 with the rotating shaft 3, ensuring that the limiting post 31 on the rotating shaft 3 corresponds one-to-one with the first sliding groove 141 on the inner wall of the sleeve 14. Then, insert the rotating shaft 3 into the sleeve 14 along the axial direction of the sleeve 14. At this time, the limiting post 31 slides downward along the vertical trajectory of the first sliding groove 141 until it reaches the bottom of the first sliding groove 141. Rotate the brush head support 1 around the axial direction of the sleeve 14, causing the sleeve 14 to rotate synchronously. At this time, the limiting post 31 enters the horizontally set second sliding groove 142 from the bottom of the first sliding groove 141 and continues to slide along the horizontal trajectory of the second sliding groove 142 until it reaches the end of the second sliding groove 142, completing the circumferential position transition. When the limiting post 31 slides to the end of the second sliding groove 142, the limiting post 31 enters the vertically upward limiting groove 143 connected to the second sliding groove 142, preventing relative displacement between the rotating shaft 3 and the sleeve 14.

[0023] A spring 4 is installed inside the sleeve 14. A push plate 5 is fixedly connected to the top of the spring 4. The push plate 5 can contact the rotating shaft 3 and make the limiting post 31 on the rotating shaft 3 stuck in the limiting groove 143.

[0024] After the rotating shaft 3 is inserted, it contacts the push plate 5. The push plate 5 transmits the axial pressure of the rotating shaft 3 to the spring 4. After the limiting post 31 slides to the end of the second slide groove 142, the spring 4 releases its elastic potential energy, and applies an upward thrust to the rotating shaft 3 through the push plate 5, pushing the limiting post 31 into the limiting groove 143. During the cleaning operation, the spring 4 always remains in a pre-compressed state, and the push plate 5 continuously applies force to the rotating shaft 3 to ensure that the limiting post 31 is stuck in the limiting groove 143.

[0025] The bottom of the brush head support 1 is equipped with a detachable brush head unit 2. The brush head support 1 serves as the mounting carrier for the brush head unit 2, providing a stable assembly reference for various functional brush heads (such as hard-bristled brush heads, soft-bristled brush heads, and sponge brush heads), ensuring the brush head unit 2 remains structurally stable during cleaning operations. Secondly, it enables connection and adaptation with the main unit of the washer. Through its integrated top structure, it cooperates with the main unit components, allowing the entire brush head assembly to be stably installed on the washer, while simultaneously transmitting the power generated by the main unit drive, ensuring the normal execution of cleaning actions. The brush head unit 2 includes a support plate 21 and several bristle bundles 22 disposed at the bottom of the support plate 21. A second magnet 212 is disposed at the center of the top of the support plate 21, and a support groove 11 is disposed at the center of the bottom of the brush head support 1 to cooperate with the second magnet 212. A first magnet 13 is fixed in the support groove 11. When the second magnet 212 is inserted into the support groove 11, the first magnet 13 can be attracted to the second magnet 212. The support groove 11 and the second magnet 212 are hexagonal. Both the brush head support 1 and the support plate 21 are made of plastic.

[0026] The brush head unit 2, as the actuating component that directly acts on the surface to be cleaned, consists of a support plate 21 and several bristle bundles 22. It is detachably installed at the bottom of the brush head support 1, providing users with convenient brush head replacement options to adapt to different cleaning scenarios. The support plate 21 is made of plastic, the same material as the brush head support 1, offering excellent lightweight advantages, reducing overall weight, and facilitating operation. The second magnet 212, located at the center of its top, cooperates with the support groove 11 at the center of the bottom of the brush head support 1 and the first magnet 13 fixed within the groove. Utilizing the attraction between opposite magnetic poles, a quick and stable connection is achieved between the brush head unit 2 and the brush head support 1. Furthermore, both the support groove 11 and the second magnet 212 are designed as hexagons. Through unique shape adaptation, the positioning accuracy and stability during connection are further improved, preventing circumferential displacement of the brush head unit 2 during rotational cleaning. Several bristle bundles 22 are evenly distributed at the bottom of the support plate 21. They rotate at high speed under the drive of the brush head support 1. Through the high-frequency friction between the bristles and the surface to be cleaned, they effectively remove various stains and are the direct action element for achieving the cleaning function.

[0027] Several guide rails 12 are vertically arranged on the inner wall of the bottom of the brush head support 1, and guide grooves 211 corresponding to the guide rails 12 are formed around the support plate 21. During the pre-assembly process, the guide grooves 211 slide and engage with the guide rails 12, allowing the support plate 21 to move smoothly along the vertical trajectory of the guide rails 12, ensuring that the movement direction of the support plate 21 is consistent with the axis of the brush head support 1.

[0028] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. 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 should be determined by the appended claims.
