Abstract

The invention relates to a toothbrush with toothpaste pushed by a screw. The toothbrush comprises a toothbrush head and a toothbrush handle. The toothbrush head is composed of bristles and toothbrush head rod. The toothbrush is characterized by further comprising a screw pushing rod and a rotary cap, the rotary cap is fixedly connected to the tail end of the screw pushing rod, and the front section of the screw pushing rod is a toothpaste outlet switch, the middle section of the screw pushing rod is of a connection section and the back section of the screw pushing rod is of a screw section; toothpaste outlets from 1 to 10 are formed in the toothbrush head rod; the insides of the toothbrush head rod and the toothbrush handle are of cylindrical cavities, the front section and the middle section of the screw pushing rod are mounted in the cavity of the toothbrush head rod, and the rear section of the screw pushing rod is mounted in the cavity of the toothbrush handle; the rotary cap is movably matched with the end tail of the toothbrush handle, 1-4 bumps are formed in the inner wall of the rotary cap and matched with a groove in circle in the outer wall of the tail end of the toothbrush handle, and 1-4 rotary angle sensing points are formed in the groove. The toothbrush is simple in structure, allows quantitative squeezing of the toothpaste and prevention of the toothpaste in the toothbrush handle from pollution and is adaptable to a user with one hand disabled and blind people.

Example Embodiment

[0023] Example one
[0024] A toothpaste type toothbrush pushed by a screw rod comprises a toothbrush head 1, a toothbrush handle 2, a screw propelling rod 3 and a rotating cap 4. The toothbrush head 1 is composed of toothbrush bristles 11 and a toothbrush head shaft 12. The rotating cap 4 is fixedly connected to the end of the screw rod 3; the front part of the screw rod 3 is a toothpaste outlet switch 31, the middle part is a connecting part 32, and the rear part is a spiral part 33; there are two toothpaste outlets 121 on the toothbrush head rod 12 ; The toothbrush head rod 12 and the toothbrush handle 2 are both cylindrical cavities, the front and middle sections of the screw rod 3 are placed in the cavity of the toothbrush head rod 12, and the back section of the screw rod 3 is placed in the cavity of the toothbrush handle Inside; the rotating cap 4 and the end of the toothbrush handle 2 movably cooperate, the inner wall of the rotating cap 4 has two convex points 41, which match a ring of groove 21 on the outer wall of the end of the toothbrush handle 2, and the groove 21 is also provided with 4 The rotation angle senses the bump 211.
[0025] In this embodiment, the toothbrush head 1 and the toothbrush handle 2 are integrated and cannot be separated into separate parts, which are mainly suitable for one-time use.

Example Embodiment

[0026] Example two
[0027] A toothpaste type toothbrush pushed by a screw rod comprises a toothbrush head 1, a toothbrush handle 2, a screw propelling rod 3 and a rotating cap 4. The toothbrush head 1 is composed of toothbrush bristles 11 and a toothbrush head shaft 12. The rotating cap 4 is fixedly connected to the end of the screw rod 3; the front part of the screw rod 3 is a toothpaste outlet switch 31, the middle part is a connecting part 32, and the rear part is a spiral part 33; there are two toothpaste outlets 121 on the toothbrush head rod 12 ; The toothbrush head rod 12 and the toothbrush handle 2 are both cylindrical cavities, the front and middle sections of the screw push rod 3 are placed in the cavity of the toothbrush head rod 12, and the back section of the screw push rod 3 is placed in the cavity of the toothbrush handle Inside; the rotating cap 4 and the end of the toothbrush handle 2 movably cooperate, the inner wall of the rotating cap 4 has two convex points 41, which match a ring of groove 21 on the outer wall of the end of the toothbrush handle 2, and the groove 21 is also provided with 4 The rotation angle senses the bump 211.
[0028] The toothbrush head 1 and the toothbrush handle 2 are connected by screwing and fitting, so that the user can change the toothbrush head regularly as needed, which not only ensures oral hygiene, but also saves resources and is beneficial to environmental protection.
[0029] The toothbrush handle is provided with a toothpaste filling hole 22. After the toothpaste is used up, the user can fill the toothpaste by himself, which can be reused.
