Description

Technical Field

[0001] The utility model relates to a U-shaped toothbrush head, in particular to a split and detachable U-shaped toothbrush head. Background Art

[0002] The U-shaped toothbrush head, also known as a lazy toothbrush head, has a U-shaped brush head similar to the tooth arrangement in the oral cavity. The U-shaped toothbrush head has some unique features and usage methods, but some matters need to be noted during use to ensure its cleaning effect and safety. For children, the U-shaped toothbrush head is a toothbrushing tool worth trying; for adults, they need to choose a toothbrushing tool suitable for themselves according to their oral conditions and needs.

[0003] The existing Chinese patent technology 202321496807.X relates to a U-shaped toothbrush, including a toothbrush handle and a toothbrush head. The top of the toothbrush handle is fixedly connected with a connecting part, and one end of the connecting part away from the toothbrush handle is fixedly connected with an arc part. A jack is opened in the middle of the side of the toothbrush head, and an arc groove is opened inside the toothbrush head. The arc groove communicates with the jack. The connecting part is inserted into the jack, and the arc part is inserted into the arc groove. The shape of the toothbrush head is U-shaped. The material of the toothbrush head is silica gel. Grooves are opened at the top and bottom of the toothbrush head, and the shape of the groove is arc-shaped. The utility model is convenient for replacing the toothbrush head, facilitating people's use, and the U-shaped toothbrush can be placed on the desktop, away from accumulated water, so that the toothbrush head remains dry, avoiding the toothbrush head from causing pollution and infecting the oral cavity.

[0004] Although the prior art is convenient for replacing the toothbrush head, facilitating people's use, and the U-shaped toothbrush can be placed on the desktop, away from accumulated water, so that the toothbrush head remains dry, avoiding the toothbrush head from causing pollution and infecting the oral cavity, its bristles and the brush head are still an integrated structure. When the user needs to replace it after using it for a period of time, the whole needs to be replaced by the staff, and the bristles cannot be replaced separately, resulting in a relatively high replacement cost.

Detailed implementation manners

[0027] Refer to Figures 1 - 10As shown in the figure, the technical solution adopted in this specific embodiment is as follows: It includes a dental brace main body 2, a fixed plastic part 4 is installed inside the dental brace main body 2, several toothbrush bristles 5 are installed on the dental brace main body 2, and an inner small guard plate 1 is installed on the inner side above the dental brace main body 2, and an outer large guard plate 3 is installed on the outer side below the dental brace main body 2. The inner walls of the inner small guard plate 1 and the outer large guard plate 3 are both in contact with the outer ends of the toothbrush bristles 5.

[0028] More specifically, a middle positioning block 12 is provided in the middle of the outer end of the inner small guard plate 1, and a small guard plate fixing convex block 11 is provided at the vertex of the outer end of the inner small guard plate 1. The inner small guard plate 1 is installed on the dental brace main body 2 through the small guard plate fixing convex block 11 and the middle positioning block 12, and the middle positioning block 12 can simultaneously position the relative position of the inner small guard plate 1 to prevent unnecessary displacement of the inner small guard plate 1 during use.

[0029] More specifically, several small bristles 22 are provided at both the front and rear ends of the dental brace main body 2, several bristle mounting holes 23 are provided at both the upper and lower ends of the dental brace main body 2, an inner fixing groove 26 is provided at the vertex of the upper end of the dental brace main body 2, an outer fixing groove 21 is provided at the vertex of the lower end of the dental brace main body 2, an extended end head 25 is fixedly connected to the middle of the lower end of the dental brace main body 2, and a bottom reinforcement plate 24 is provided between the dental brace main body 2 and the extended end head 25. The outer fixing groove 21 cooperates with the large guard plate fixing convex block 31 to facilitate the installation of the outer large guard plate 3, while the inner fixing groove 26 cooperates with the small guard plate fixing convex block 11 to enable the inner small guard plate 1 to be better installed on the dental brace main body 2. The bristle mounting holes 23 facilitate the installation of the toothbrush bristles 5, and the small bristles 22 and the toothbrush bristles 5 can increase the brushing area.

[0030] More specifically, a middle convex part is formed in the middle of the inner side of the outer large guard plate 3 to form an outer middle positioning block 32, a large guard plate fixing convex block 31 is provided at the vertex of the inner side of the outer large guard plate 3, and an end head guard plate 33 is fixedly connected to the middle of the outer large guard plate 3. The outer fixing groove 21 cooperates with the large guard plate fixing convex block 31 to facilitate the installation of the outer large guard plate 3, and the outer middle positioning block 32 can position the installation position of the outer large guard plate 3 to prevent unnecessary displacement of the outer large guard plate 3. Among them, the end head guard plate 33 is used to wrap and protect the extended end head 25.

[0031] More specifically, the fixed plastic part 4 includes a connecting end head 43, U-shaped plates 42 are fixedly connected to both ends of the connecting end head 43, and several positioning convex blocks 41 are provided on the U-shaped plates 42. The U-shaped plates 42 and the connecting end head 43 are used to increase the support strength of the dental brace main body 2 and are positioned through the positioning convex blocks 41.

[0032] More specifically, the toothbrush bristles 5 are composed of a bristle head 51 and a fixed bottom plate 52, and the bristle head 51 is fixedly connected to the fixed bottom plate 52.

[0033] More specifically, the inner small guard plate 1, the dental appliance main body 2, and the outer large guard plate 3 are all made of silicone. Silicone is a highly active adsorbent material, insoluble in water and any solvent, non-toxic and odorless, and has stable chemical properties.

[0034] More specifically, the toothbrush bristles 5 are nylon bristles. Nylon bristles have high wear and durability, and at the same time have good elasticity and high temperature resistance.

[0035] The working principle of the present utility model: When in use, the user should install a suitable handle through the connection end 43. After the installation is completed, the user can use the device for normal tooth cleaning operations. When it is necessary to replace the toothbrush bristles 5 or perform a deep cleaning, the user only needs to detach the inner small guard plate 1 and the outer large guard plate 3 from the dental appliance main body 2 so that the toothbrush bristles 5 can be detached separately. At this time, the user can detach the toothbrush bristles 5 according to their own needs to replace the corresponding toothbrush bristles 5 or perform a deep cleaning. After the replacement or cleaning is completed, the user only needs to reinstall the toothbrush bristles 5 at the bristle installation hole 23 and reinstall the inner small guard plate 1 and the outer large guard plate 3 back. Among them, the small bristles 22 and the toothbrush bristles 5 can cooperate with each other to further ensure the tooth cleaning operation of the user.

[0036] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model should be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
