Technical Field
[0001] This utility model relates to the technical field of bathing utensils, and in particular to a three-section telescopic bath brush. Background Technology
[0002] In daily life, bath brushes are a common personal hygiene tool widely used during bathing to help users clean their bodies. However, existing bath brushes are usually designed with a fixed length, which has significant limitations and cannot meet the needs of users with different body types. For example, users with broad shoulders or a larger build may find it difficult to clean certain parts of their body due to the brush being too short, thus affecting their user experience. Furthermore, fixed-length bath brushes take up considerable space when hanging and storing, causing inconvenience for users. Therefore, the market urgently needs a bath brush with an adjustable length to adapt to the needs of different users and optimize storage efficiency.
[0003] Currently, while some extendable rod-shaped tools exist on the market, their designs are often quite simple, with limited adjustable length units and insufficient structural stability, making it difficult to meet the strength and durability requirements of bath brushes during use. Furthermore, most existing bath brush heads are fixedly installed, making it inconvenient to disassemble for cleaning or to replace different types of brush heads. This not only affects cleaning effectiveness but may also lead to hygiene problems. In addition, traditional bath brushes have shortcomings in terms of anti-slip performance and portability, further limiting their versatility in various usage scenarios. Based on these issues, developing a bath brush with multi-section telescopic functionality, flexible length adjustment, support for quick brush head disassembly and assembly, and good anti-slip properties and convenient storage has become a pressing technical challenge.

[0019] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. When the number of elements is referred to as "multiple," it can be any number of two or more. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:
[0023] The three-section telescopic bath brush consists of a first support rod 1, a second support rod 2, and a third support rod 3, which are connected in a telescopic manner to achieve length adjustment. Figures 1 to 5 The specific embodiments of this utility model will be described in detail below.
[0024] The first support rod 1 is the thinnest section, with an opening at its top. A pair of L-shaped grooves 9 are symmetrically arranged inside the opening. Figure 2 As shown. The bottom of the brush head 7 has a pair of snap-fit blocks 8, which engage with the L-shaped groove 9 to achieve a detachable connection. When installing the brush head 7, align the snap-fit blocks 8 of the brush head 7 with the vertical section of the L-shaped groove 9 and insert them until the snap-fit blocks 8 reach the horizontal section of the L-shaped groove 9. Then rotate the brush head 7 to move the snap-fit blocks 8 along the horizontal section and complete the engagement. This design allows the brush head 7 to be securely fixed to the first support rod 1, while also facilitating disassembly for cleaning or replacement with different types of brush heads 7. For example, users can choose soft-bristled brush heads, hard-bristled brush heads, or silicone brush heads according to their needs, improving usability.
[0025] Both the second support rod 2 and the third support rod 3 are cylindrical sleeve structures, with a deep hole at the center of their top extending axially inwards. Figure 1 and Figure 4As shown. The diameter of the second support rod 2 is larger than that of the first support rod 1, so the first support rod 1 can be inserted into the deep hole of the second support rod 2 and slidably connected to it. Similarly, the diameter of the third support rod 3 is larger than that of the second support rod 2, so the second support rod 2 can be inserted into the deep hole of the third support rod 3 and slidably connected to it. To ensure that the relative positions between the support rods are fixed, limit blocks 6 are fixedly installed at the openings near the top inside the deep holes of the second support rod 2 and the third support rod 3, respectively. The size of the limit block 6 is adapted to the width of the slide groove 4, so that it can slide freely on the slide groove 4 but will not detach from the slide groove 4. Multiple communicating positioning grooves 5 are provided on one side of the slide groove 4. The positioning grooves 5 are arranged in a linear array along one side of the slide groove 4, and the depth is slightly greater than the height of the limit block 6. When it is necessary to adjust the length between the support rods, push the support rod to slide it along the slide groove 4. When the limit block 6 moves to the position of the target positioning groove 5, it is locked into the positioning groove 5. For example, when a user wants to extend the length of the shower brush, they simply pull the first support rod 1 and the second support rod 2, causing the limiting block 6 to disengage from the current positioning groove 5 and slide into a more distant positioning groove 5, thus increasing the length. Conversely, when the length needs to be shortened, the support rods are pushed to slide the limiting block 6 into a closer positioning groove 5. This design allows the shower brush to be flexibly adjusted in length according to the user's height, body type, or usage scenario, meeting the needs of different users.
[0026] In practical use, the telescopic function of this invention is particularly useful. For example, for users with broad shoulders and a larger build, the first support rod 1, the second support rod 2, and the third support rod 3 can be extended to the maximum length of the bath brush, making it easy to brush the back or other hard-to-reach areas. For children or smaller users, the support rods can be retracted to a shorter length to avoid affecting operation due to excessive length. Furthermore, the storage of this invention is also more convenient. When not in use, the first support rod 1 is fully inserted into the second support rod 2, and then the second support rod 2 is fully inserted into the third support rod 3, significantly shortening the overall length of the bath brush and reducing its space occupation. The top of the third support rod 3 is also equipped with a hanging ring 11, with a diameter between 10 mm and 15 mm, made of the same material as the third support rod 3, ensuring the consistency and aesthetics of the overall structure. Users can use the hanging ring 11 to hang the bath brush on hooks on the bathroom wall, further saving space.
[0027] To further enhance the user experience, the surface of the third support rod 3 is provided with anti-slip texture 10, such as... Figure 3 As shown. The anti-slip texture consists of raised stripes or dots, with a height set between 0.5 mm and 1 mm. This design increases friction when gripping, preventing the shower brush from slipping in wet environments and improving safety during use. For example, when the user's hands are wet or have shower gel in the shower, the anti-slip texture 10 effectively enhances the grip between the hand and the third support 3, preventing accidental slippage.
[0028] Regarding the cleaning and replacement of the brush head 7, the design of this utility model fully considers hygiene and convenience. Since the brush head 7 is detachably connected to the first support rod 1, the user can easily remove the brush head 7 for cleaning. For example, when dirt or bacteria accumulate on the brush head 7, the user simply rotates the brush head 7 to disengage the locking block 8 from the L-shaped groove 9, and then rinses the brush head 7 with clean water. After cleaning, the brush head 7 is reinstalled onto the first support rod 1, ensuring that the locking block 8 accurately engages in the horizontal section of the L-shaped groove 9 to complete the fixation. Furthermore, users can replace the brush head 7 with different types according to personal preference or cleaning needs. For example, a soft-bristled brush head is suitable for users with sensitive skin, while a hard-bristled brush head is more suitable for users who require deep cleaning. This modular design not only enhances the functionality of the product but also extends its service life.
[0029] The operating principle of this invention is based on the cooperation of the sliding groove 4, the positioning groove 5, and the limiting block 6, as well as the connection mechanism between the L-shaped groove 9 and the snap-fit block 8. Taking the connection between the first support rod 1 and the second support rod 2 as an example, the limiting block 6 is fixed inside the deep hole of the second support rod 2 near the top opening, and its size is adapted to the width of the sliding groove 4, allowing it to slide freely on the sliding groove 4. When the user needs to adjust the length, he pushes the first support rod 1 to slide along the sliding groove 4, and the limiting block 6 moves accordingly. When the limiting block 6 reaches the position of the target positioning groove 5, it is snapped into the positioning groove 5 to complete the locking. The same principle applies to the connection between the second support rod 2 and the third support rod 3. This design not only realizes flexible length adjustment, but also ensures a stable connection between the support rods, avoiding loosening or detachment during use.
[0030] In summary, this utility model solves the problems of inconvenience and storage difficulties caused by the fixed length of existing bath brushes through the telescopic design of the three-section support rod, the cooperation between the sliding groove 4 and the positioning groove 5, and the structure of the detachable brush head 7. Its specific implementation covers all aspects from structural design to practical application, fully demonstrating the technical advantages and practicality of this utility model. For example, in a family setting, family members of different heights can share the same bath brush, adjusting the length to meet their individual needs; in a travel setting, users can retract the bath brush to its shortest length and hang it using the hanging ring 11, reducing the space occupied by luggage. These features give this utility model high market promotion value and wide applicability.
[0031] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made 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.
