Example

[0038] Please see Figures 1-8 A convenient toothbrush includes a brush head structure 1 and a handle structure 2, characterized in that: the inside of the handle structure 2 is hollow so that the brush head structure 1 can extend and retract freely therein; a first connector 101 is connected to the bottom of the brush head structure 1; a second connector 201 is connected to the top of the handle structure 2; and the first connector 101 and the second connector 201 are locked together by a locking structure 3.

[0039] The portable toothbrush of this application mainly consists of a brush head structure 1, a brush handle structure 2, a first connector 101, a second connector 201, a locking structure 3, a dust cover 4, and a handheld handle sleeve 5. The following is a detailed description of its structure and working principle.

[0040] (a) Component assembly

[0041] Brush head and connector assembly: The brush head structure 1, the first connector 101, and the second connector 201 are integrated into one piece. This means that during the production process, they are integrally formed using a specific mold, ensuring the strength of the connection.

[0042] Brush handle and connector assembly: The brush handle structure 2 is connected to the second connector 201 via a positioning connecting ring 2011. During assembly, the second connector 201 is aligned with the opening of the brush handle structure 2, and then the positioning connecting ring 2011 is used to fix the two together, ensuring the coaxiality of the brush handle structure 2 and the second connector 201 and preventing loosening.

[0043] Assembly of locking structure 3: Locking structure 3 consists of a first locking sleeve 301 and a second locking sleeve 302. During assembly, it is necessary to ensure that the first locking sleeve 301 and the second locking sleeve 302 can rotate freely relative to each other, and the outer wall of the second locking sleeve 302 is uniformly glued with anti-slip textured ridges 3022 for anti-slip purposes and to facilitate operation.

[0044] Handle sleeve 5 installation: The handle sleeve 5 is fitted onto the bottom of the brush handle structure 2. The outer surface of the handle sleeve 5 has anti-slip grooves, which are formed by mold during the manufacturing of the handle sleeve 5. Its bottom is designed to be parallel and has evenly distributed water-permeable bottom holes 503, which are covered with a filter layer 504. During assembly, it is necessary to ensure that the filter layer 504 can effectively prevent dust from entering while allowing water to drain out.

[0045] Dust cover 4 installation: A dust cover 4 is installed at the bottom of the brush handle structure 2. The top of the dust cover 4 is connected to the bottom of the hand handle sleeve 5 via a magnetic structure 401. During assembly, the dust cover 4 is fixed to the bottom of the hand handle sleeve 5 by magnetic attraction, and the front view of the dust cover 4 is narrow at the top and wide at the bottom, which fits with the bottom plane of the hand handle sleeve 5.

[0046] Connection between the brush head and the handheld handle sleeve 5: The bottom outer ring of the brush head structure 1 is connected to the clip 501. When installing the handheld handle sleeve 5, the clip 501 must be accurately inserted into the groove with the stabilizing ring 502 at the bottom of the handheld handle sleeve 5 and form a tight contact to ensure a stable connection.

[0047] (II) Usage Process (From Storage to Use)

[0048] Unlock and stretch

[0049] When the user needs to use the toothbrush, they first grasp the handle structure 2. The handle sleeve 5 at the bottom of the handle structure 2 has anti-slip grooves, which increase the friction between the hand and the handle, preventing slippage during operation. Then, the user begins to rotate the locking structure 3. Since the locking structure 3 consists of a first locking sleeve 301 and a second locking sleeve 302, and the second connecting member 201 is designed to be approximately twice the height of the locking structure 3, this design allows the first locking sleeve 301 to rotate sufficiently relative to the threaded portion of the first connecting member 101 when the locking structure 3 is rotated. When rotating the locking structure 3 disengages the first locking sleeve 301 from the external thread of the first connecting member 101, the lock on the first connecting member 101 at the bottom of the brush head structure 1 is released. At this time, the brush head structure 1 begins to extend from inside the handle structure 2 under the influence of gravity. During the extension of the brush head structure 1, the sliding blocks 102 fixedly connected around the first connecting member 101 slide within the sliding grooves 202 opened inside the handle structure 2 and the second connecting member 201. The top of the sliding groove 202 is designed to be open, which allows the sliding block 102 to slide out smoothly, thereby allowing the brush head structure 1 to be completely pulled out of the second connector 201, realizing the separation of the brush head structure 1 from the brush handle structure 2. This design not only makes it convenient for users to clean the brush head, but also allows for easy replacement of the brush head structure 1 when the brush head is damaged.

[0050] The auxiliary role of stabilizing structures

[0051] During the entire process of the brush head structure 1 extending from the brush handle structure 2, the stabilizing structure composed of the sliding block 102 and the sliding groove 202 plays a crucial role. The sliding of the sliding block 102 within the sliding groove 202 ensures the stability of the brush head structure 1 during extension and retraction. Because the size and shape of the sliding block 102 and the sliding groove 202 are precisely matched, the sliding of the sliding block 102 within the sliding groove 202 is smooth and free from wobbling, ensuring user comfort and product reliability during operation.

[0052] (III) The storage process (from use to storage)

[0053] Contraction and Locking

[0054] After using the toothbrush, the user needs to retract the brush head structure 1. First, the user pushes the brush head structure 1 upwards back into the handle structure 2. This process is relatively simple; the user only needs to push the brush head structure 1 back along the internal channel of the handle structure 2. Then, the user rotates the locking structure 3, causing the first locking sleeve 301 to re-engage with the external thread of the first connecting member 101, thereby locking the brush head structure 1 and keeping it in the retracted state. When rotating the locking structure 3, since the threads of the first locking sleeve 301 and the first connecting member 101 are precisely matched, the locking function can be easily achieved through rotation.

[0055] Use of dust cover 4

[0056] When the brush head structure 1 is fully retracted into the brush handle structure 2, the user can remove the dust cover 4 from the bottom of the handle sleeve 5. Since the dust cover 4 has a groove that matches the opening of the first locking sleeve 301 in the locking structure 3, after removing the dust cover 4, it can be placed over the first locking sleeve 301. At this time, the groove in the dust cover 4 can accurately fit onto the first locking sleeve 301, serving as a dustproof function. Simultaneously, when the dust cover 4 is placed over the first locking sleeve 301, it generates a certain amount of friction with the outer wall of the first locking sleeve 301. This friction improves the stability of the connection between the dust cover 4 and the first locking sleeve 301, preventing the dust cover 4 from accidentally falling off during transport.

[0057] II. Working Principle

[0058] (I) Locking and Unlocking Principles

[0059] Threaded fit mechanism

[0060] The first locking sleeve 301 and the second locking sleeve 302 of the locking structure 3 engage with the external threads of the first connector 101 and the second connector 201 via their internal threads, thereby achieving the locking and unlocking functions of the brush head structure 1. When the user rotates the locking structure 3, the first locking sleeve 301 and the second locking sleeve 302 rotate relative to the first connector 101 and the second connector 201. In the locked state, the first locking sleeve 301 is tightly engaged with the thread of the first connector 101. This tight engagement restricts the movement of the brush head structure 1, keeping it in the extended state for convenient brushing. When the user needs to store the toothbrush, rotating the locking structure 3 disengages the first locking sleeve 301 from the thread of the first connector 101. At this time, the brush head structure 1 can freely extend and retract inside the brush handle structure 2, achieving the function of storing the brush head.

[0061] Convenience of rotary operation

[0062] The uniformly glued anti-slip texture 3022 on the outer wall of the second locking sleeve 302 not only serves as an anti-slip surface but also provides a better grip for the user during rotation. When rotating the locking structure 3, the user can more easily grip the second locking sleeve 302 for operation, ensuring a smooth and stable rotation process.

[0063] (II) Principle of Stable Structure

[0064] Sliding fit mechanism

[0065] The stable structure formed by the sliding block 102 and the sliding groove 202 is crucial to ensuring the stability of the brush head structure 1 during extension and retraction. The sliding block 102 is fixedly connected to the lower end of the outer wall of the first connector 101, and the sliding groove 202 is formed around the inner wall of the brush handle structure 2 and the second connector 201. When the brush head structure 1 extends or retracts within the brush handle structure 2, the sliding block 102 slides within the sliding groove 202. The opening at the top of the sliding groove 202 allows the sliding block 102 to slide out, ensuring that the brush head structure 1 can fully extend and retract. Because the dimensions and shape of the sliding block 102 and the sliding groove 202 are precisely designed and manufactured, the sliding block 102 will not experience jamming or wobbling during its sliding within the sliding groove 202, effectively preventing the brush head structure 1 from shaking within the brush handle structure 2, thus improving user comfort and product reliability.

[0066] (III) Dustproof and drainage principles

[0067] Dust prevention mechanism

[0068] The dust cover 4 is connected to the bottom of the handle sleeve 5 via a magnetic structure 401. When the brush head structure 1 is stored, the dust cover 4 is removed from the bottom of the handle sleeve 5 and placed over the outside of the first locking sleeve 301, with the groove inside the dust cover 4 fitting into the first locking sleeve 301. This design not only prevents dust from entering the brush handle structure 2 and protects the cleanliness of the brush head, but also prevents bacterial growth to a certain extent. The rubber layer at the bottom of the dust cover 4 increases the friction with the placement surface when placed, further enhancing the stability of the placement surface when the handle sleeve 5 is placed on a flat surface, and also preventing tipping. During the production process, the quality and installation position of the magnetic structure 401 and the rubber layer of the dust cover 4 are strictly tested and controlled to ensure the functional effect of the dust cover 4.

[0069] Drainage mechanism

[0070] The permeable bottom holes 503 at the bottom of the handle sleeve 5 are designed to allow water to drain by gravity when the retracted brush head structure 1 carries residual water in an emergency. The filter layer 504 covering the permeable bottom holes 503 is replaceable and its function is to allow water penetration while preventing dust from entering. During design and manufacturing, the size and distribution density of the permeable bottom holes 503 are optimized to ensure a balance between drainage efficiency and dust prevention. The filter layer 504 is made of a material with a certain porosity and filtration performance, and during assembly, it is ensured to completely cover the permeable bottom holes 503, guaranteeing effective drainage and dust prevention.
