Examples

Referring to fig. 1, an embodiment of the present invention provides a toothbrush comprising: a brush head 10 and a brush stem 20.

Wherein, the toothbrush head 10 is provided with a brush 11 for brushing teeth, and the toothbrush head 10 is detachably connected with the toothbrush rod body 20.

The toothbrush rod body 20 comprises a storage structure 21 and a feeding structure 22, and the bottom end of the feeding structure 22 is connected with the top end of the storage structure 21. The storage structure 21 is internally provided with a first cavity 211 for storing toothpaste, the feeding structure 22 is internally provided with a second cavity 221, a first discharge hole 31 is arranged between the feeding structure 22 and the storage structure 21, and the first discharge hole 31 is communicated with the first cavity 211 and the second cavity 221.

The top end of the feeding structure 22 is provided with a second discharge port 32 communicated with the second cavity 221, and the second discharge port 32 is used for supplying toothpaste to the toothbrush head 10.

A first one-way valve 311 and a second one-way valve 321 are respectively arranged at the first discharge hole 31 and the second discharge hole 32, the first one-way valve 311 controls toothpaste to enter the second cavity 221 from the first cavity 211, and the second one-way valve 321 controls toothpaste to move from the second cavity 221 to the second discharge hole 32.

The surface of the feeding structure 22 is provided with an operating part 23, the operating part 23 is connected with an extruding part, the extruding part partially extends into the second cavity 221, and the extruding part and the second cavity wall are arranged in a sealing manner.

The operating portion 23 controls the volume of the extrusion portion extending into the second cavity 221. The volume of the squeezing portion extending into the second chamber 221 is increased, and the toothpaste is squeezed to move through the second check valve 321 to the second outlet 32. The volume of the squeezing portion extending into the second chamber 221 is reduced and toothpaste is pumped through the first one-way valve 311 and into the second chamber 221.

As shown in fig. 1, in some embodiments of the present invention, the bottom of the magazine 21 is provided with an air intake hole 24 communicating with the first cavity 211.

A moving part 25 is arranged in the first cavity 211, the moving part 25 is sealed with the inner wall of the first cavity 211 and can move along the inner wall of the first cavity 211, and the moving part 25 is positioned between the air inlet 24 and the first discharge hole 31. The air inlet hole 24 makes one end of the moving part 25 always under atmospheric pressure, and when the pressure of the toothpaste at one end of the moving part 25 is reduced, the atmospheric pressure pushes the moving part 25 to move towards the first discharge hole 31. Alternatively, the positions of the air intake holes 24 may be set on the bottom-end side wall of the magazine 21.

Optionally, the bottom end of the moving portion 25 may be connected with a push rod or provided with a spring, so that the moving portion 25 extrudes the toothpaste to a certain extent in the process of reducing the toothpaste, and the toothpaste provided to the second cavity 221 is always present at the first discharge hole 31.

As shown in fig. 1, the magazine bottom 26 is detachably provided with the magazine main body. When the toothpaste in the storage structure 21 is used up and needs to be added, the bottom 26 of the storage structure is detached, and the moving part 25 is taken out to fill the toothpaste. Alternatively, the moving part 25 is a rubber stopper.

As shown in fig. 1, in the present invention, the operation portion 23 may be an elastic button, and when the elastic button is not pressed by an external force, the pressing portion is returned to the initial position. Wherein, when the pressing portion is located at the initial position, the volume extending into the second cavity 221 is minimum. Specifically, by pressing the elastic button disposed on the outer wall of the feeding structure 22, the squeezing portion extends into the second cavity 221 to squeeze toothpaste to flow from the second one-way valve 321 to the second discharge port 32, and after the elastic button is reset, the squeezing portion is gradually drawn out from the second cavity 221, so that the reduced space in the second cavity 221 is vacuumed, and under the action of the vacuum, the first one-way valve 311 is opened, and toothpaste is replenished into the second cavity 221 from the first cavity 211. Further, the moving portion 25 is also moved toward the first discharge hole 31 by the atmospheric pressure, so that the pressures at both sides of the moving portion 25 are the same.

In an embodiment of the present invention, as shown in fig. 1, the bottom end of the toothbrush head 10 is removably connected to the top end of the dosing structure 22. The bottom end of the toothbrush head 10 is provided with a groove 12, and the second discharge hole 32 is wrapped in the groove 12 to protect the toothpaste discharge hole. Optionally, the top of the dosing structure 22 is provided with external threads and the bottom recess of the toothbrush head 10 is provided with internal threads, the dosing structure 22 being removably connected to the toothbrush head 10 by threads.

According to the technical scheme, the toothbrush is easy to carry due to the integrated arrangement of the toothpaste and the toothbrush, the structures for storing the toothpaste and providing the toothpaste are simplified due to the matching arrangement of the feeding structure 22 and the storage structure 21, so that a single toothbrush can store more toothpaste, the supply operation of the toothpaste is simpler and more convenient, and the toothbrush is more sanitary and cleaner due to the independent arrangement of the protection structure of the toothpaste outlet.

Although the utility model has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the utility model. Accordingly, such modifications and improvements are intended to be within the scope of the utility model as claimed.
