Description

Disposable toothbrush

This creation is related to the structure of toothbrushes, especially the structure of toothbrushes that self-supply toothpaste.

According to the press, teeth are the organs that people use to chew foods. The quality and firmness of teeth directly affect people's quality of life. Therefore, in recent years, people have paid more and more attention to dental health. After eating a meal, you will get used to brushing your teeth to clean your teeth.

The existing toothbrush is usually applied with toothpaste or dentifrice on the bristles of the toothbrush head, and then the mouth (such as teeth, gums or tongue) is washed with the bristles of the brush head. Some users will bring toothbrushes when they are used to Convenient for tooth cleaning; but in order to clean your teeth, you usually need to carry toothpaste in addition to the toothbrush. Separating the two will not only increase weight, but also take up space, causing problems that are not easy to carry. Besides, toothbrush and toothpaste are stored separately. In addition to the loss of waste, accidentally it will be squeezed out and contaminate the surrounding items.

The folding toothbrush set as described in the Republic of China New Patent Certificate No. M556567 patent is composed of a brush handle, the brush handle has a first frame handle and a second frame handle which are relatively pivoted, and the The first frame handle and the second frame handle can be selectively opposed to each other. The first frame handle is formed with a storage compartment corresponding to the second frame handle, and the first frame handle is different from the pivotal end of the second frame handle. A brush head is protruded, and the brush head has a set of bristles, and the second frame handle is formed with a storage compartment whose opening corresponds to the first frame handle.

However, the toothpaste in the above patent is placed in the storage compartment of the brush handle. In the case that the storage space of the storage compartment is limited, the user needs to specially prepare a smaller volume of toothpaste to be placed in the storage compartment. The storage compartment of the toothbrush handle has a certain volume, and it still cannot effectively save luggage space.

The main purpose of this creation is to provide a disposable toothbrush, which has the advantages of saving space occupied by toothpaste and improving user convenience.

In order to achieve the above-mentioned creation purpose, a disposable toothbrush disclosed in this creation includes a head, a handle connected to the head, and a plurality of bristles provided on one of the top sides of the head. Lies in: a receiving slot is set on the head. A through hole is provided on the top side of the head, and the through hole is in communication with the accommodation groove. A toothpaste is disposed in the accommodation slot. One end of a piston is located in the accommodation groove of the head, and the other end is outside the accommodation groove. The piston is pressed to push the toothpaste in the accommodation groove, so that the toothpaste flows from the through hole to the top side of the head.

In an embodiment, the piston has a pressing portion and a protrusion, and the protrusion is located in the receiving hole.

In one embodiment, the bump has an internal contraction surface, and a toothpaste channel is formed between the internal contraction surface and the inner wall surface of the through hole.

In one embodiment, an isolation layer is further formed. The isolation layer is formed by curing the toothpaste, and the isolation layer is located at the interface between the toothpaste flow channel and the through hole.

In an embodiment, the head has a bottom side, and the other side of the top side is located, and the accommodation hole is disposed on the bottom side.

The above-mentioned objects and advantages of this creation can be obtained from the detailed description and accompanying drawings of the selected embodiments below.

Please refer to FIG. 1. The toothbrush structure provided by the self-supplying toothpaste provided by the preferred embodiment of the present invention includes: a head 10, a handle 24, and a plurality of bristles 26. The head 10 is generally rectangular parallelepiped, and has a top side 12, a bottom side 14, a front side 16, a rear side 18, a left side 20, and a right side 22. One end of the handle 24 is connected to the rear side 18 of the head 10, and the bristles 26 are disposed on the top side 12 of the head 10. The bottom side 14 is located on the other side of the top side 12, the front side 16 is located on the other side of the rear side 18, and the left side 20 and the right side 22 are on the other two sides of the cuboid. The above is the same as a normal toothbrush, and it will not be described in detail here. The improvements of this creation are as follows:

Referring to FIG. 2, an accommodating groove 28 is radially formed on the bottom side 14 of the head 10 of the toothbrush. The accommodating groove 28 has a predetermined depth. A through hole 30 is formed in the top side 12 of the head portion 10 in a radial direction. The through hole 30 has a predetermined depth, and the through hole 30 is in communication with the accommodation groove 28. In this embodiment, the number of the accommodating grooves 28 and the through holes 30 are two.

A piston 32 has a pressing portion 34 having a plate-like body. A side of the pressing portion 34 extends outward to form a protrusion 36, and the length of the protrusion 36 and the length of the through hole 30 correspond to each other. The pressing portion 34 of the piston 32 is movably installed in the receiving hole of the head 10, and the protrusion 36 of the piston 32 is located in the through hole 30 of the head 10. In this embodiment, the number of the pistons 32 is two.

Please refer to FIG. 3 for reference. A plurality of constricted surfaces 38 are formed on the circumferential surface of the bump 36, and each of the constricted surfaces 38 is an arc surface formed by being concave in the radial direction. In a state where the projection 36 of the piston 32 is located in the through-hole 30, a toothpaste flow path 40 is formed between the constricted surface 38 of the projection 36 and the inner wall surface of the through-hole 30, and the toothpaste flow path 40 is in communication with the accommodation slot 28.

Referring to FIG. 4, a toothpaste 42 is located in the receiving groove 28 of the head 10 and the toothpaste runner 40. An isolation layer 44 is formed at the interface between the toothpaste runner 40 and the through hole 30. It is worth noting that the isolation layer 44 is formed by using the characteristic that the toothpaste 42 will solidify after being in contact with the outside air for a period of time. Therefore, in the initial state, the toothpaste 42 located in the toothpaste channel 40 will not flow out to the top side 12 of the head 10.

Please refer to FIG. 5. When a user wants to use his toothbrush to brush his teeth, he only needs to press one of the pistons 32 and move the piston 32 toward the top side 12 of the head 10. At this time, the piston 32 The pressure generated by the inward movement will cause the isolation layer (not shown) to rupture, so that the toothpaste 42 of the accommodation groove 28 can flow 40 to the top side 12 of the head 10 through the toothpaste flow channel, and is located at each of the The bristles are between 26, so the user can start brushing.

Please refer to Figures 5 and 6. This creation has the advantage that the supply of toothpaste 42 can be adjusted according to the actual needs of users. For example, if the user cleans the mouth with a small amount of the toothpaste 42, he only needs to press one of the pistons 32 to squeeze out the appropriate amount of the toothpaste 42 (as shown in Figure 5); otherwise, if he uses Those who are accustomed to brushing with more toothpaste 42 can press the other piston 32 to squeeze out the toothpaste 42 in another receiving slot (as shown in Figure 6), so that the second supply of toothpaste can be achieved. The purpose of 42.
