Description

A new type of convenient toothbrush

technical field

The invention relates to a tooth cleaning tool for oral care, in particular to a portable toothbrush integrated with brushing paste.

Background technique

Toothpaste and toothbrush used in daily life generally exist and sell independently, and when going out on a trip, toothpaste and toothbrush will be carried respectively. This feature has brought many problems to the people who often travel: 1, in order to prevent the toothbrush head from being polluted, usually the toothbrush is wrapped in a plastic bag or a certain packing box, which is inconvenient to use and carry; In the process of carrying, the soft toothpaste tube is often squeezed to cause the toothpaste to overflow; 3. Sometimes, in order to solve the problem that the toothbrush and toothpaste are not easy to carry, people often use disposable toothbrush utensils, which have potential hygiene problems. And a large amount of disposable utensils bring great pressure to the environment and cause the waste of a large amount of resources. For these problems, many people have proposed improvement measures, such as the technical scheme of Chinese patent CN202396789U, which includes a storage tube for storing toothpaste, the brush rod is hinged with the toothpaste cover, and the toothpaste cover is screwed with the storage tube to realize the foldable toothbrush. Toothpaste integration function, but this solution does not solve the problem that the toothbrush head is easily contaminated, and does not explain how to use the storage tube for storing toothpaste. Both the Chinese utility model patent CN203608998U and the Chinese utility model patent CN202035670U have proposed a scheme for integrating toothbrush and toothpaste, but their schemes connect the toothpaste and the toothbrush head through holes. The disadvantage of this scheme is that water will As the holes enter the toothpaste body, the toothpaste is contaminated and bacteria grow. Chinese utility model patent CN202999793U discloses a solution that the toothbrush head, toothbrush handle, and toothpaste tube are independent. A disadvantage of this solution is that it is inconvenient to use. Therefore, the prior art solves some problems to a certain extent, but still has the shortcomings of our aforementioned toothbrush heads that are easy to pollute, not easy to carry, and not environmentally friendly. More importantly, for the prior art toothbrush and toothpaste are integrated In most of the solutions, the toothpaste is not tightly sealed, and water is easy to enter, causing the toothpaste in the toothpaste bag to be diluted by water, and even cause pollution and breed bacteria.

Contents of the invention

Aiming at the problems in the prior art that the toothbrush head is easily polluted, the toothbrush is not easy to carry, it is not environmentally friendly, and the tube body of the toothpaste is not tightly sealed, the present invention discloses a new solution to solve the above technical problems, and provides a toothbrush head that is not easily polluted by the toothpaste. A new type of portable toothbrush that can be loaded and unloaded, and the brush body can be recycled.

In order to solve the above problems, the technical solution adopted in the present invention is:

A new type of convenient toothbrush, comprising a brush head 1 and a brush handle 2, the brush head 1 and the brush handle 2 are detachably connected, one side of the brush head 1 has bristles 3, and the brush handle 2 is a brush with a cavity structure inside. The handle 2a and the brush handle 2b are composed, the inner cavity of the brush handle 2a constitutes the brush head cavity 5 for accommodating the brush head 1, the inner cavity of the brush handle 2b forms the toothpaste tube 4 for accommodating toothpaste, and the brush head 1 is connected to the brush handle 2a through the connecting head 12 One end of the brush handle 2a is movably connected, and the other end of the brush handle 2a is closed by the bottom surface 11b of the brush handle 2a, and the outer surface of the bottom surface 11b is fixedly provided with a threaded shaft 8, and one end of the brush handle 2b has an outlet nozzle 13 of toothpaste, which is connected with the nozzle 13 The corresponding pipe cap 7 can seal the nozzle 13, and the other end of the brush handle 2b is fastened to the lock groove 18 through the lock rail 17 on the bottom surface 11a of the brush handle 2b to be flexibly connected with the brush handle 2a. The hole in the center of the bottom surface 11a of the brush handle 2b enters the toothpaste tube 4, and the brush handle 2b can rotate with the axis of the threaded shaft 8 as the axis of rotation relative to the axis of the brush handle 2a. There is a piston 6 with a hole in the center of the toothpaste tube 4 , the toothpaste can be squeezed out from the nozzle 13, and the hole wall in the center of the piston 6 has a thread corresponding to the threaded shaft 8. When the threaded shaft 8 rotates relative to the handle 2b, the piston 6 can be made to and fro along the toothpaste tube 4 Formula sliding, toothpaste can be squeezed out when moving toward an end of toothpaste mouth 13.

As a preferred solution, in order to make the connection between the brush head 1 and the handle 2 simple, the connection between the toothbrush head 1 and the handle 2 can be a movable bolt connection, and the cross section of the connecting head 12 can be made into a circle, Ellipse or polygon etc., also can be threaded connection, now there are external threads on the connector 12, the inner surface of the brush handle 2a has corresponding internal threads, the middle part of the connector 12 has a circle of protruding tendons 14, to prevent the connector 12 is completely inserted into the brush head cavity 5, and the outer diameter of the connecting head 12 is greater than the outer diameter of the largest part of the toothbrush head 1, so that the toothbrush head can be inserted into the brush head cavity 5 smoothly.

As a preferred solution, in order to make the invention reusable and realize the purpose of environmental protection, at the end of the brush handle 2b near the nozzle 13, the brush handle 2b is a detachable movable connection connected by a threaded structure, after the toothpaste is used up It is convenient to inject toothpaste into the toothpaste tube 4 .

As a preferred solution, the connection between the pipe cap 7 and the nozzle 13 can be a lock-type connection or a threaded connection, that is, through the nozzle external thread 9a on the nozzle 13 and the nozzle internal thread 9b on the pipe cap 7. The seal of the cap to the nozzle.

As a preferred solution, in order to prevent water from entering the toothpaste tube 4 from the hole in the bottom surface 11a when brushing teeth, and to prevent toothpaste from overflowing from the hole in the bottom surface 11a, a water seal 15 is provided on the hole wall of the bottom surface 11a, and the corresponding threaded shaft 8 There is a sealing groove 15 at the end of the handle. When the brush handle 2a and the brush handle 2b are fully engaged, the water seal 15 is just embedded in the sealing groove 15 to realize the sealing of the hole.

As a preferred solution, in order to prevent the piston 6 from rotating with the threaded shaft 8, the outer edge of the piston has more than one groove, and the inner wall of the toothpaste tube 4 has a corresponding number of convex rails. When the piston 6 slides in the toothpaste tube 4, Groove is stuck on the convex rail, makes piston 6 can not rotate relative to toothpaste tube 4.

The beneficial effects of the present invention are: (1) the toothbrush and toothpaste are assembled in one piece, but are independent of each other, the toothpaste has good sealing performance, the toothpaste tube is not easy to enter water, and bacteria are prevented from growing; (2) safe and hygienic, because the toothbrush head can be disassembled Put it into the brush head cavity to prevent the toothbrush head from being polluted; (3) It is easy to carry. When not in use, put the toothbrush head into the brush head cavity. (4) Environmental protection and no waste. Since the toothbrush head is a movable connection, the toothbrush head can be sold separately, and the brush handle can be recycled, avoiding environmental pollution and resource waste caused by throwing away the entire toothbrush every time the toothbrush head is replaced; (5) The invention is simple and easy to use, convenient to use, convenient to industrialized production and market promotion, and has good commercial prospects.
