Abstract
Description
Technical Field
[0001] This utility model relates to the field of toothbrush technology, and in particular to a toothbrush with a rapidly pop-out toothbrush head. Background Technology
[0002] As an important tool for personal oral care, the history of toothbrushes can be traced back thousands of years. Early people used various natural materials such as willow branches and animal bristles to clean their teeth. It wasn't until the 15th century, during the Ming Dynasty in China, that people began to fix animal bristles (usually pig bristles) to handles made of bamboo or bone. This is considered the prototype of the modern toothbrush. However, it wasn't until 1938 that the invention of nylon fibers ushered in a new era for toothbrushes. DuPont developed the first nylon toothbrush, which quickly became popular due to its soft and even properties.
[0003] To make them easy to carry, existing toothbrushes are usually designed with a storage cavity to hold the brush head and bristles. However, when the toothbrush needs to be used, the user has to manually pull the brush head and bristles out of the storage cavity. This process cannot be done automatically. Because the efficiency of pulling out the brush head and bristles is low, it affects the user experience. Utility Model Content
[0004] The main purpose of this invention is to propose a toothbrush with a quick-release toothbrush head, which aims to solve the technical problem that when a toothbrush is needed, the user needs to manually pull the brush head and bristles out of the storage cavity, and this process cannot achieve automatic ejection.
[0005] To achieve the above objectives, the present invention proposes a toothbrush with a quickly pop-out toothbrush head, including a handle, a cavity inside the handle, a brush head inside the cavity, and a limiting component on the handle to facilitate the quick pop-out of the brush head.
[0006] The limiting assembly includes a limiting hole, a limiting groove, a sliding groove, a fixing groove, a limiting block, a limiting rod, a telescopic spring, a knob, a threaded groove, and a lead screw. The limiting hole is located inside the brush handle and communicates with the cavity. The limiting groove is located inside the brush handle and communicates with the limiting hole. The sliding groove is located on the inner wall of the cavity. The fixing groove is located on the inner wall of the cavity and communicates with the sliding groove. The limiting block is located on the brush head and is slidably connected to the inner wall of the sliding groove. The limiting rod is located on the brush head, with its other end extending through to the inside of the limiting hole. The telescopic spring is located between the inner wall of the cavity and the brush head and is sleeved on the limiting rod. The knob is located on the limiting groove, with its other end extending to the outside of the brush handle. The threaded groove is located inside the knob and communicates with the limiting hole. The lead screw is located on the limiting rod.
[0007] Optionally, the outer wall of the brush head is slidably connected to the inner wall of the cavity.
[0008] Optionally, the height of the fixing groove is adapted to the height of the limiting block.
[0009] Optionally, the diameter of the limiting rod is adapted to the diameter of the limiting hole.
[0010] Optionally, the knob is in the shape of an I-shape.
[0011] Optionally, the diameter of the lead screw is smaller than the diameter of the limiting rod.
[0012] The technical solution of this utility model has the following beneficial effects: When the user needs to remove the brush head for use, the knob is turned to separate the lead screw from the threaded groove. Then, through the reaction force of the telescopic spring, the brush head quickly pops upward under the limitation of the limiting hole, limiting rod, sliding groove and limiting block. Then, the brush head is rotated clockwise to rotate the limiting block into the fixed groove, thereby limiting the brush head, so that the user can use it stably and the operation is simple and convenient.

[0023] This invention proposes a toothbrush with a rapidly pop-out brush head.
[0024] like Figures 1 to 4 As shown, in one embodiment of the present invention, the toothbrush with a quick-pop toothbrush head includes a handle 1, a cavity 2 is provided inside the handle 1, a brush head 3 is provided inside the cavity 2, the diameter of the upper bristle portion of the brush head 3 is smaller than the diameter of its lower end, so that the brush head 3 can be stored inside the cavity 2, and a limiting component 4 is provided on the handle 1 to facilitate the quick pop-out of the brush head 3.
[0025] The limiting component 4 includes a limiting hole 41, a limiting groove 42, a sliding groove 43, a fixing groove 44, a limiting block 45, a limiting rod 46, a telescopic spring 47, a knob 48, a threaded groove 49, and a lead screw 410. The limiting hole 41 is opened inside the brush handle 1 and communicates with the cavity 2. The limiting groove 42 is opened inside the brush handle 1 and communicates with the limiting hole 41. The sliding groove 43 is opened on the inner wall of the cavity 2. The fixing groove 44 is opened on the inner wall of the cavity 2 and communicates with the sliding groove 43. The limiting block 45 is located on the brush head. The brush head 3 is slidably connected to the inner wall of the slide groove 43. The limiting rod 46 is located on the brush head 3, and the other end extends through to the inside of the limiting hole 41. The telescopic spring 47 is located between the inner wall of the cavity 2 and the brush head 3, and is sleeved on the limiting rod 46. The telescopic spring 47 abuts against the bottom of the brush head 3. The knob 48 is located on the limiting groove 42, and the other end extends to the outside of the brush handle 1. The threaded groove 49 is opened inside the knob 48 and communicates with the limiting hole 41. The lead screw 410 is located on the limiting rod 46.
[0026] Specifically, the outer wall of the brush head 3 is slidably connected to the inner wall of the cavity 2.
[0027] Specifically, the height of the fixing groove 44 is matched with the height of the limiting block 45. The fixing groove 44 can conveniently limit the limiting block 45, so that the brush head 3 can play a stable limiting role when the user brushes their teeth.
[0028] Specifically, the diameter of the limiting rod 46 is matched with the diameter of the limiting hole 41. The limiting hole 41 limits the limiting rod 46, making it easier for the limiting rod 46 to slide up and down.
[0029] Specifically, the knob 48 is in the shape of an I-shape, so that the limiting groove 42 can conveniently limit the movement of the knob 48.
[0030] Specifically, the diameter of the lead screw 410 is smaller than the diameter of the limiting rod 46, which facilitates the movement of the lead screw 410 inside the limiting hole 41. The size of the lead screw 410 is matched with the size of the thread groove 49, and the thread groove 49 facilitates the limiting of the lead screw 410.
[0031] Specifically, the working principle and usage process of this utility model are as follows:
[0032] When the user needs to remove the brush head 3 for use, turn the knob 48 to separate the lead screw 410 from the threaded groove 49. Then, through the reaction force of the telescopic spring 47, the brush head 3 is quickly ejected upward under the limitation of the limiting hole 41, the limiting rod 46, the sliding groove 43 and the limiting block 45. Then, rotate the brush head 3 clockwise to rotate the limiting block 45 into the fixed groove 44, thereby limiting the brush head 3 and making it stable for the user to use.
[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
