Abstract
Description
Technical Field
[0001] This utility model relates to the field of toothbrush technology, and in particular to a one-button pop-out toothbrush. Background Technology
[0002] Oral hygiene is a crucial part of daily health care, and as a core tool, the ease of use and safe storage of toothbrushes are always key user concerns. Currently, most mainstream toothbrush products on the market feature a fixed-length, integrated structure. This design has significant portability drawbacks in practical use: because the brush head and handle are fixed and cannot be separated or retracted, the toothbrush is relatively large, taking up considerable space in toiletry bags and suitcases when stored. Especially in scenarios with tight storage space requirements, such as short trips or business trips, fixed-length toothbrushes are difficult to fit into small portable containers, greatly reducing portability and causing inconvenience for users.
[0003] To address this issue, a small number of foldable toothbrush products have appeared on the market, but these products still have significant shortcomings: their folding structure usually relies on the cooperation of multiple sets of hinges, buckles and other complex components. After repeated folding and use over a long period of time, components are prone to loosening, wear and tear at the joints or even breakage, which directly leads to a shortened lifespan of the toothbrush. At the same time, the steps are cumbersome and cannot meet users' needs for "quick access and convenient operation". Utility Model Content
[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a one-button pop-out toothbrush.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A one-button pop-out toothbrush includes a housing and a brush handle located at the upper end of the housing. The upper end of the brush handle is provided with a brush head, and the lower end is movable up and down within the housing. When the brush handle is retracted into the housing, it is in a retracted state; when it is extended out of the housing, it is in an extended state. A limiting protrusion is provided on one side of the brush handle and inside the housing to prevent the brush handle from sliding out of the housing. A first spring is provided at the lower end of the limiting protrusion to pop the brush handle upward. The one-button pop-out toothbrush further includes a locking component for locking the brush handle in the retracted or extended state. An unlock button is also provided on the housing. The unlock button cooperates with the locking component to unlock the locking component, thereby switching the brush handle between the retracted and extended states.
[0007] In some embodiments, the locking assembly includes an upper locking groove and a lower locking groove disposed on the front side of the brush handle and spaced apart vertically, and a locking pin that can be engaged in the upper locking groove or the lower locking groove. A swing plate is also rotatably disposed within the housing. The locking pin is disposed on the upper rear side of the swing plate. When the locking pin is engaged in the upper locking groove, the brush handle is retracted. When the locking pin is engaged in the lower locking groove, the brush handle is extended. A second spring is disposed on the upper front side of the swing plate, which always laterally abuts against the upper front side of the swing plate. The lower front side of the swing plate abuts against the rear end of the unlock button.
[0008] In some embodiments, a circular groove is provided on the upper front side of the swing plate, and a limiting post is provided on the inner wall of the housing. One end of the second spring abuts against the circular groove, and the other end is sleeved on the limiting post.
[0009] In some embodiments, a raised strip is provided on the lower front side of the swing plate, and an arc-shaped groove that cooperates with the raised strip is provided on the rear end of the unlock button.
[0010] In some embodiments, a spring fixing post is provided at the lower end of the limiting protrusion, and one end of the first spring is engaged with the spring fixing post.
[0011] In some embodiments, the housing includes a front housing and a rear housing.
[0012] In some embodiments, a plurality of mounting holes are provided at the inner edge of the rear housing, and a plurality of mounting posts that mate with the mounting holes are provided at the inner edge of the front housing.
[0013] In some embodiments, the front shell and the rear shell are fixed by ultrasonic welding.
[0014] In some embodiments, a cover is removably fitted onto the brush head.
[0015] In some embodiments, the shell is shaped like an animal's body, and the cover is shaped like an animal's head.
[0016] In summary, compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This one-button pop-up toothbrush features a core design where the handle can extend and retract within the housing, allowing for flexible switching between retracted and extended modes. In the retracted mode, the handle is stored inside the housing, significantly reducing the overall length and size of the toothbrush. It can easily fit into a small toiletry bag, cosmetic bag, or even a pocket, perfectly suited for short trips, business trips, and other scenarios where storage space is critical. This completely solves the problem of traditional fixed-length toothbrushes taking up too much space and being inconvenient to carry, greatly improving the flexibility of carrying it while traveling.
[0018] 2. Compared to the complex hinge structure of foldable toothbrushes, this toothbrush adopts a simplified structural design with a shell, telescopic handle, and limiting protrusion. On the one hand, the limiting protrusion effectively limits the extension range of the handle, preventing it from falling off due to excessive extension and ensuring structural stability. On the other hand, the telescopic design reduces friction and wear between components (eliminating the need for repeated folding and joint rotation), and the locking component and unlocking button have a simple and reliable working structure, making them less prone to loosening or damage. This fundamentally solves the problems of easy damage and short lifespan of foldable toothbrushes, significantly improving the product's durability.
[0019] 3. This toothbrush simplifies the form-changing process through a linkage mechanism between the unlock button, locking component, and first spring. Users simply press the unlock button on the housing, releasing the locking component from the handle. The spring force quickly extends the handle to its extended position for direct oral cleaning. To store, first press the unlock button, then press the handle down into the housing; the locking component will automatically lock it in its retracted position. The entire operation is simple, completely eliminating the cumbersome operation of traditional foldable toothbrushes and providing a highly efficient, instant-use experience.

[0025] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.
[0026] like Figures 1 to 4 The one-button pop-out toothbrush is characterized by comprising a housing 1 and a brush handle 2 located on the upper end of the housing 1. The upper end of the brush handle 2 is provided with a brush head 3, and the lower end is movable within the housing 1. When the brush handle 2 is retracted into the housing 1, it is in a retracted state; when it is extended out of the housing 1, it is in an extended state. A limiting protrusion 4 is provided on one side of the brush handle 2 and inside the housing 1 to prevent the brush handle 2 from sliding out of the housing 1. A first spring 5 is provided at the lower end of the limiting protrusion 4 to pop the brush handle 2 upward. The one-button pop-out toothbrush further includes a locking component for locking the brush handle 2 in the retracted or extended state. An unlocking button 6 is also provided on the housing 1. The unlocking button 6 cooperates with the locking component to unlock the locking component, thereby switching the brush handle 2 between the retracted and extended states.
[0027] When the toothbrush is in the retracted state, the brush handle 2 is completely retracted into the housing, and the locking component is in the locked state, which firmly fixes the brush handle 2 in the housing 1. At this time, the limiting protrusion 4 on one side of the brush handle 2 is located at a specific position in the inner cavity of the housing 1, and the first spring 5 at its lower end is in a state of energy storage (deformation energy storage) due to the compression of the brush handle 2. When the user needs to use the toothbrush, simply press the unlock button 6 on the housing 1. The unlock button 6 and the locking component form a mechanical engagement. The pressing action will trigger the locking structure of the locking component to release the fixation of the brush handle 2. After the lock is released, the first spring 5, which is in a charged state, will release its elastic potential energy and generate an upward driving force, pushing the limiting protrusion 4 to move upward, thereby causing the brush handle 2 to slide upward along the inner cavity of the housing 1. When the brush handle 2 slides to the preset position, the limiting protrusion 4 on one side of the brush handle 2 will contact the upper wall of the inner cavity of the housing 1, restricting the brush handle 2 from continuing to slide upward and preventing the brush handle 2 from sliding completely out of the housing. At this time, the brush head 1 at the upper end of the brush handle is fully extended out of the housing, and the toothbrush switches to the extended form, which can be used directly for oral cleaning. When the user is finished using the toothbrush and needs to store it, first manually release the unlock button 6 downwards to release the fixation of the brush handle 2. Then, press down on the brush handle 2 that is protruding from the housing. After the brush handle 2 is subjected to downward pressure, it slides down along the inner cavity of the housing 1, causing the limiting protrusion 4 to move downwards in sync. The first spring 5 at the lower end of the limiting protrusion 4 is compressed again and re-enters the charging state. As the brush handle 2 continues to slide downwards, when the lower end of the brush handle 2 is completely retracted into the housing, release the unlock button 6. The locking component will automatically trigger to fix the brush handle 2 back into the housing. At this time, the toothbrush returns to its retracted state, and the storage is completed.
[0028] See Figures 2-4As shown, the locking assembly includes an upper locking groove 21 and a lower locking groove 22 located on the front side of the brush handle 2 and spaced apart vertically, and a locking pin 24 that can be engaged in the upper locking groove 21 or the lower locking groove 22. A swing plate 23 is also rotatably arranged inside the housing 1. The locking pin 24 is located on the upper rear side of the swing plate 23. When the locking pin 24 is engaged in the upper locking groove 21, the brush handle 2 is in a retracted state. When the locking pin 24 is engaged in the lower locking groove 22, the brush handle 2 is in an extended state. A second spring 25 is provided on the upper front side of the swing plate 23, which always laterally abuts against the upper front side of the swing plate 23. The lower front side of the swing plate 23 abuts against the rear end of the unlock button 6.
[0029] Specifically, when the toothbrush is in its retracted state, the lower end of the brush handle 2 is completely retracted into the housing 1. At this time, the locking assembly is in the following state: the upper locking groove 21 on the front side of the brush handle 2 is precisely aligned with the locking pin 24 on the rear side of the upper end of the swing plate 23 inside the housing 1. The second spring 25 pushes the upper end of the swing plate 23 to tilt rearward, so that the locking pin 24 is firmly locked into the upper locking groove 21. At the same time, the lower front side of the swing plate 23 always abuts against the rear end of the unlock button 6, forming a stable mechanical contact. In this state, the engagement structure between the locking pin 24 and the upper locking groove 21 restricts the up and down sliding of the brush handle, firmly locking the brush handle 2 in the retracted state, while the first spring 5 is in a stored state due to the compression of the brush handle 2.
[0030] When the user presses the unlock button 6 on the housing 1, the unlock button 6 pushes the lower front of the swing plate 23 to the rear. Since the swing plate 23 is a rotating structure inside the housing 1, after the lower end is pushed backward, it will swing forward around the rotation axis (lever principle), causing the upper end of the swing plate 23 to tilt forward synchronously. During this process, the second spring 25 on the upper front of the swing plate 23 is compressed (stores elastic potential energy), and the locking pin 24 on the upper rear side disengages from the upper locking groove 21 with the swing, releasing the lock on the brush handle 2. After the lock is released, the first spring 5, which is in the stored state, releases its elastic force, pushing the limiting protrusion 4 and the brush handle 2 to slide upward until the brush handle 2 switches to the extended state. At this time, the force of the user pressing the unlock button 6 disappears, the second spring 25 on the upper front of the swing plate 23 releases its elastic potential energy, pushing the upper end of the swing plate 23 to return to its original tilt, so that the locking pin 24 automatically locks into the lower locking groove 22. At the same time, the lower front of the swing plate 23 abuts against the rear end of the unlock button 6 again, restoring the initial contact state. The engagement structure between the locking post 24 and the lower locking groove 22 restricts the brush handle from sliding up and down, and securely locks the brush handle in the extended position, allowing the user to use the toothbrush normally to clean the mouth.
[0031] A circular groove 31 is provided on the upper front side of the swing plate 23, and a limiting post 32 is provided on the inner wall of the housing 1. One end of the second spring 25 abuts against the circular groove 31, and the other end is sleeved on the limiting post 32. Thus, during long-term high-frequency use of the toothbrush, the cooperation between the circular groove 31 and the limiting post 32 can continuously ensure the stable operation of the second spring 25.
[0032] See Figure 3 As shown, a protrusion 41 is provided on the lower front side of the swing plate 23, and an arc-shaped groove 42 that cooperates with the protrusion 41 is provided on the rear end of the unlock button 6.
[0033] In traditional planar contact mating, the swing plate 23 is prone to misalignment and jamming with the unlock button 6 due to component machining errors or assembly gaps when rotating. The mating of the protrusion 41 and the arc-shaped groove 42 solves this problem through arc-shaped trajectory guidance; the protrusion can slide along the inner wall of the arc-shaped groove, and the arc structure perfectly matches the rotation trajectory of the swing plate, ensuring that the two remain in contact during relative movement without jamming or misalignment.
[0034] See Figure 4 As shown, a spring fixing post 51 is provided at the lower end of the limiting protrusion 4, and one end of the first spring 5 is locked on the spring fixing post 51 to improve the stability of the first spring 5 after installation.
[0035] In this utility model, the housing 1 includes a front housing 61 and a rear housing 62. A plurality of mounting holes 71 are provided on the inner edge of the rear housing 62, and a plurality of mounting posts 72 that cooperate with the mounting holes 71 are provided on the inner edge of the front housing 61. The front housing 61 and the rear housing 62 are fixed by ultrasonic welding.
[0036] During assembly, the operator must align the mounting posts 72 of the front shell 61 with the mounting holes 71 of the rear shell 62 one by one, and insert the mounting posts 72 into the mounting holes 71; ensure that the edges of the front shell 61 and the rear shell 62 are completely aligned to avoid local offset or misalignment; after the pre-assembly is completed, the front shell and the rear shell must be permanently fixed by ultrasonic welding process.
[0037] In this invention, a cover (not shown in the attached drawings) is detachably attached to the brush head 3. The shape of the shell 1 is similar to that of an animal body, and the shape of the cover is similar to that of an animal head.
[0038] When the toothbrush is not in use (such as when stored or carried), the cover can be detachably attached to the brush head 2. The inner side of the cover has a groove that fits the contour of the brush head. The user simply aligns the cover with the top of the brush head and presses it downwards along the brush head axis to securely attach the cover to the outside of the brush head. When closed, the cover completely covers the bristles of the brush head, forming a physical protective barrier to prevent the bristles from being directly exposed to the external environment. At the same time, the detachable design of the cover ensures that it will not obstruct the normal use of the brush head and should only be closed when protection is needed.
[0039] The shell is designed to resemble the shape of an animal's body (such as a bear's torso or a rabbit's body), while the lid is designed to resemble the shape of an animal's head (such as a bear's head or a rabbit's head). When closed, they form a complete animal-like shape. When the lid is closed on the brush head, the brush head retracts into the shell along with the handle. At this time, the animal-like head on the lid aligns axially with the animal-like body on the shell, forming a complete animal shape with head and body. Even when the handle is extended, the animal-like body shape on the shell maintains its independent appearance when the lid is removed and stored separately, while the animal-like head shape on the lid can also be considered an independent component. This consistent design strengthens the overall visual connection of the product. This design is not merely decorative; rather, through the logical coordination of the body and head, it makes the product's appearance more cohesive and easily recognizable.
[0040] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
