Description

Technical Field

[0001] This utility model relates to the field of toothbrush technology, specifically to a toothbrush made of biodegradable composite fiber material. Background Technology

[0002] Toothbrushes are essential tools for cleaning teeth. They clean the surface of teeth, thus improving their protection. To ensure that toothbrushes do not damage teeth during cleaning, modern toothbrushes generally use fine bristles. When these bristles come into contact with the tooth surface, they bend under pressure, preventing them from harshly cleaning the teeth. At the same time, the use of fine bristles allows for better cleaning of the finer areas of the teeth, improving the cleaning effect.

[0003] Toothbrushes, as oral hygiene tools, are fast-moving consumer goods. After a few months of use, the bristles of a toothbrush will bend and deform, making it unable to effectively clean teeth. At this point, users will discard the entire toothbrush and replace it with a new one, which results in serious waste of resources. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a biodegradable composite fiber toothbrush.

[0005] The technical solution of this utility model is implemented as follows: A biodegradable composite fiber toothbrush includes a handle, on which a replacement connecting mechanism is provided. A connecting shell is fixedly connected to one end of the handle. A sliding groove is opened on one side of the connecting shell. A slider is slidably connected inside the sliding groove on the connecting shell. A connecting block is fixedly connected to one side of the slider. A rotating rod is rotatably connected inside the connecting shell. A connecting rod is fixedly connected to the outer circular surface of the rotating rod. A cylindrical head is fixedly connected to one side of the connecting rod. A locking block is fixedly connected to the other end of the connecting rod. A fixing block is fixedly connected to the other end of the connecting rod. A spring is fixedly connected to the outside of the cylindrical head. A toothbrush head is provided at one end of the connecting shell. A slot is opened at one end of the toothbrush head. A locking groove is opened inside the toothbrush head. Bristles are fixedly connected to the top of the toothbrush head.

[0006] Preferably, the fixing block is in the shape of a right trapezoid, and the side of the connecting block adjacent to the fixing block is an arc surface.

[0007] Preferably, the connecting shell has a first water flow channel inside, the toothbrush head has a second water flow channel inside, and the toothbrush head has a third water flow channel inside.

[0008] Preferably, the second water channel on the toothbrush head is connected to the slot on the toothbrush head.

[0009] Preferably, a guide block is fixedly connected inside the connecting shell.

[0010] Preferably, the guide block is triangular in shape.

[0011] Preferably, a first ventilation hole is provided on one side of the toothbrush head, and a second ventilation hole is provided at the other end of the toothbrush head.

[0012] This utility model has the following beneficial effects:

[0013] 1. This biodegradable composite fiber toothbrush works by pushing the sliders on both sides of the connecting shell. The sliders cause the connecting block to slide on the inclined surface of the fixed block, which in turn moves the fixed block. The fixed block then moves the connecting rod and the locking block. The connecting rod then drives the rotating rod to rotate inside the connecting shell, and the locking block moves out of the slot on the toothbrush head. After the connecting rod and the locking block have moved, they are no longer than the length of the slot on the toothbrush head. At this point, the toothbrush head can be removed from the connecting shell and replaced with a new one. This allows for toothbrush head replacement, avoiding the disposal of the entire toothbrush and reducing resource waste.

[0014] 2. This biodegradable composite fiber toothbrush, after brushing, allows water inside the brush head to flow into the connecting shell when the brush head is placed upwards. Then, the water is guided out through the first water channel by the guide block inside the connecting shell. When the brush head is placed downwards, the water inside the connecting shell flows into the brush head and out through the third water channel. At the same time, the first and second ventilation holes promote air circulation between the brush head and the connecting shell, allowing the water inside the brush head and the connecting shell to dry quickly and reducing bacterial growth.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-7 As shown, the biodegradable composite fiber toothbrush provided in this embodiment includes a handle 1. A connecting mechanism 2 for replacement is provided on the handle 1. A connecting shell 201 is fixedly connected to one end of the handle 1. A groove 204 is provided on one side of the connecting shell 201. A slider 203 is slidably connected inside the groove 204 on the connecting shell 201. A connecting block 205 is fixedly connected to one side of the slider 203. A rotating rod 206 is rotatably connected inside the connecting shell 201. The outer surface of the rotating rod 206 is fixedly connected to... There is a connecting rod 207, a cylindrical head 208 is fixedly connected to one side of the connecting rod 207, a locking block 209 is fixedly connected to the other end of the connecting rod 207, a fixing block 210 is fixedly connected to the other end of the connecting rod 207, a spring 211 is fixedly connected to the outside of the cylindrical head 208, a toothbrush head 202 is provided at one end of the connecting shell 201, a slot 212 is opened at one end of the toothbrush head 202, a locking groove 213 is opened inside the toothbrush head 202, and bristles 3 are fixedly connected to the top of the toothbrush head 202.

[0026] Furthermore, the fixing block 210 is generally in the shape of a right trapezoid, and the side of the connecting block 205 adjacent to the fixing block 210 is an arc surface.

[0027] By adopting the above technical solution, the arc surface on the connecting block 205 slides on the inclined surface of the fixing block 210, which facilitates the connecting block 205 to push the fixing block 210 to move.

[0028] Furthermore, the connecting shell 201 has a first water flow channel 5 inside, the toothbrush head 202 has a second water flow channel 6 inside, and the toothbrush head 202 has a third water flow channel 7 inside.

[0029] By adopting the above technical solution, the water that enters the connecting shell 201 and the toothbrush head 202 can flow out from the first water channel 5 on the connecting shell 201, the second water channel 6 on the toothbrush head 202, and the third water channel 7 on the toothbrush head 202.

[0030] Furthermore, the second water channel 6 on the toothbrush head 202 is connected to the slot 213 on the toothbrush head 202.

[0031] By adopting the above technical solution, the water in the slot 213 on the toothbrush head 202 can flow out from the second water channel 6 on the toothbrush head 202.

[0032] Furthermore, a guide block 4 is fixedly connected inside the connecting shell 201.

[0033] Furthermore, guide block 4 is triangular in shape as a whole.

[0034] By adopting the above technical solution, the guide block 4 is triangular in shape, which facilitates the guide block 4 to guide water to the first water channel 5 on the connecting shell 201.

[0035] Furthermore, a first ventilation hole 8 is provided on one side of the toothbrush head 202, and a second ventilation hole 9 is provided on the other end of the toothbrush head 202.

[0036] By adopting the above technical solution, the air circulation between the toothbrush head 202 and the connecting shell 201 can be promoted through the first ventilation hole 8 and the second ventilation hole 9 on the toothbrush head 202.

[0037] Working principle: When the toothbrush head 202 needs to be replaced, the sliders 203 on both sides of the connecting shell 201 can be pushed, causing the sliders 203 to move in the grooves 204 on the connecting shell 201. The sliders 203 then drive the connecting block 205 to move towards the inclined surface of the fixed block 210. The connecting block 205 then pushes the fixed block 210 along the inclined surface of the fixed block 210, which in turn drives the connecting rod 207 and the locking block 209 to move. The connecting rod 207 then drives the rotating rod 206 to rotate inside the connecting shell 201. At the same time, the connecting rod 207 drives the cylindrical head 208 to compress the spring 211. Then, the locking block 209 moves out of the slot 213 on the toothbrush head 202. After the connecting rod 207 and the locking block 209 have moved, they are no longer than the length of the slot 212 on the toothbrush head 202. At this point, the toothbrush head 202 can be removed from the connecting shell 201 and a new toothbrush head 202 can be installed. 2. Finally, reset the slider 203. The spring force of the spring 211 resets the connecting rod 207 and the locking block 209. The locking block 209 then locks into the slot 213 on the new toothbrush head 202, thus completing the replacement of the toothbrush head 202. After brushing, place the toothbrush head 202 upwards, and the water inside the toothbrush head 202 flows into the connecting shell 201. Then, the water is guided to the connecting shell 201 by the guide block 4 inside the connecting shell 201. Water flows out from the first drainage channel 5 on the shell 201, and when the toothbrush head 202 is placed downwards, the water inside the shell 201 flows into the toothbrush head 202 and flows out through the third drainage channel 7 on the toothbrush head 202. At the same time, the first ventilation hole 8 and the second ventilation hole 9 on the toothbrush head 202 can promote air circulation between the toothbrush head 202 and the shell 201, so that the water inside the toothbrush head 202 and the shell 201 can dry quickly.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
