DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0020] Example 1: Reference Figure 1-Figure 10 A toothbrush with a brush head pressure detection device includes a shell 1, and also includes: a second partition 14 is fixedly connected in the shell 1, and a plurality of driven gears 33 and a second rotating shaft 38 are respectively rotatably connected to the second partition 14, a driving gear 32 is fixedly connected to the second rotating shaft 38, and the driving gear 32 and the driven gear 33 are meshed with each other, and a sliding rod 37 is fixedly connected above the second rotating shaft 38; a rotating sleeve 34 is fixedly connected to the driven gear 33, and a sliding groove 341 is opened on the rotating sleeve 34, and a lifting rod 35 is slidably connected to the rotating sleeve 34, and a convex block 351 is fixedly connected to the lifting rod 35, and the convex block 351 slides on the sliding Groove 341; the lifting rod 35 is fixedly connected to the bearing 36, and the first rotating shaft 31 is rotatably connected to the bearing 36. The first rotating shaft 31 is slidably connected to the sliding rod 37, and the upper part of the first rotating shaft 31 is fixedly connected to the plug-in rod 24, and the plug-in rod 24 is plugged with a brush rod 2, and the brush rod 2 is fixedly connected to the toothbrush head 21, and the brush rod 2 and the toothbrush head 21 can be replaced; a main control board 5 is fixedly connected to the shell 1, and a pressure rod 51 is fixedly connected to the main control board 5, and a pressure sensor 52 is fixedly connected to the pressure rod 51, and the other side of the pressure sensor 52 is connected to the plug-in rod 24, and the main control board 5 is used to receive and process the signal of the pressure sensor 52.

[0021] In the present invention, the main control board 5 is fixed inside the shell 1 and close to one side of the toothbrush switch, so that when the user presses the switch, the signal can be quickly transmitted to the main control board 5, thereby controlling the toothbrush to perform switch and mode switching operations. The pressure rod 51 is Z-shaped, one end of which is fixed on the main control board 5, and the other end is fixed with a pressure sensor 52 on the bottom surface. The pressure rod 51 has a certain elastic deformation and keeps pressing the pressure sensor 52 so that the pressure sensor 52 is always in contact with the plug-in rod 24. When the user brushes his teeth, the pressure generated by the contact between the toothbrush head 21 and the teeth will cause the plug-in rod 24 to be slightly bent, thereby causing the pressure on the pressure sensor 52 to change. By comparing the change in the pressure difference before and after the pressure sensor 52, the pressure of the toothbrush head 21 can be detected. When the pressure of the toothbrush head 21 increases, the amplitude of the brush head swinging increases. When the pressure of the toothbrush head 21 is greater than the rated value, it will stop swinging to avoid damage to the gums caused by excessive pressure. The toothbrush head 21 swings by means of a high-frequency reciprocating rotation of the second rotating shaft 38 within a small range, thereby driving the first rotating shaft 31 and the plug-in rod 24 to rotate synchronously, and then driving the brush rod 2 and the brush head 21 to rotate. The difference from a common electric toothbrush is that when the second rotating shaft 38 rotates, the driving gear 32 can drive the driven gear 33 to rotate, so that the driven gear 33 drives the rotating sleeve 34 to rotate together. When the rotating sleeve 34 rotates, the sliding groove 341 can drive the protrusion 351 to move up and down, thereby driving the lifting rod 35 to move up and down. The lifting rod 35 is rotatably connected to the first rotating shaft 31 through the bearing 36, so that the lifting rod 35 can drive the first rotating shaft 31 to move up and down without affecting the rotation of the first rotating shaft 31 driven by the second rotating shaft 38. The sliding rod 37 is of polygonal design, so that it can drive the first rotating shaft 31 to rotate without affecting the up and down sliding of the first rotating shaft 31. As a result, the toothbrush head 21 can perform reciprocating cleaning while swinging for cleaning, which can not only increase the contact area between the toothbrush head and the teeth, but also improve the cleaning effect and deeply clean the stains between the teeth.

[0022] Example 2: Reference Figure 1-Figure 10, a toothbrush with a brush head pressure detection device, which is basically the same as Example 1, and further: a wireless charging component 12 is fixedly connected to the shell 1, and a battery 11 is fixedly connected to the wireless charging component 12, and the wireless charging component 12 is used to charge the battery 11, a first partition 13 is fixedly connected to the inside of the shell 1, and a servo motor 3 is fixedly connected to the first partition 13, and the output end of the servo motor 3 is fixedly connected to the second rotating shaft 38, a piston cylinder 4 is fixedly connected to the shell 1, and a first piston 43 is slidably connected to the piston cylinder 4, and the first piston 43 is fixedly connected to the lifting rod 35, and the lifting rod 35 is used to drive the first piston 43 to perform piston movement, and the piston cylinder 4 is connected to an air intake pipe 42, and the air intake pipe 42 is connected to the outside of the shell 1, and the outside of the shell 1 is fixedly connected to an air intake box 6, and an air guide hole 41 is opened on the air intake box 6, and the air intake box 6 is connected to the piston cylinder 4 through the air guide hole 41. The air inlet box 6 is fixedly connected to the liquid storage box 61. The bottom of the liquid storage box 61 is provided with a plurality of vents 64. The vents 64 are used to connect the liquid storage box 61 and the air inlet box 6. A plurality of limit rods 65 are fixedly connected in the liquid storage box 61. A second piston 63 is slidably connected to the limit rod 65. The liquid storage box 61 and the air inlet box 6 are both provided with threaded interfaces 73. The threaded interfaces 73 are connected with a hose 8. A cavity 23 is provided in the brush rod 2 and the toothbrush head 21. The cavity 23 and The hose 8 is connected, a through hole 22 is provided on the toothbrush head 21, and a tension spring 71 and a blocking block 72 are provided on the liquid storage tank 61, the air intake box 6 and the piston cylinder 4. The blocking block 72 is used to seal the air intake pipe 42 and the threaded interface 73. A top block 82 is fixedly connected to one end of the connection between the hose 8 and the threaded interface 73. The top block 82 is used to lift the blocking block 72. The hose 8 is rotatably connected to a converter 81, and the converter 81 is threadedly connected to the threaded interface 73.

[0023] In the present invention, the wireless charging component 12 is located at the bottom of the housing, so that when the present invention is erected on the charging stand, the distance between the wireless charging component 12 at the bottom and the charging stand is the shortest, thereby improving the charging efficiency. The first partition 13 is used to fix the servo motor 3. The servo motor 3, as a driving part, is powered by the battery 11 to reciprocate, thereby driving the second rotating shaft 38 and the driving gear 32 to rotate; When the lifting rod 35 moves up and down, the lifting rod 35 drives the first piston 43 to perform a reciprocating piston movement up and down. A one-way valve is provided at the air guide hole 41 so that the air in the piston cylinder 4 can only be discharged to the outside through the air guide hole 41, and the outside air cannot enter the inside of the piston cylinder 4 from the outside. Fig. 9As shown, the tension spring 71 and the block 72 in the piston cylinder 4 act as a one-way valve. The tension spring 71 is always in a tensioned state. When the first piston 43 moves upward to compress the air in the piston cylinder 4, the tension spring 71 pulls the block 72 to block the connection between the air inlet pipe 42 and the piston cylinder 4. At this time, the air in the piston cylinder 4 can only be discharged from the air guide hole 41 to the air inlet box 6. When the first piston 43 moves downward, negative pressure is generated in the piston cylinder 4. The tension spring 71 and the block 72 are pressed downward by the external air pressure due to the air pressure difference. The connection between the air inlet pipe 42 and the piston cylinder 4 is opened, thereby realizing the air intake effect from the outside to the piston cylinder 4. The first piston 43 performs reciprocating motion in this way, thereby realizing the effect of charging from the piston cylinder 4 to the air inlet box 6. The middle part of the piston cylinder 4 is designed with a round hole, so as to avoid interference between the plug-in rod 24 and the piston cylinder 4 during the movement. like Figure 7 As shown, the air intake box 6 and the liquid storage box 61 are both connected with a threaded interface 73, and the threaded interface 73 is also provided with a tension spring 71 and a block 72. When the adapter 81 is connected to the threaded interface 73, the top block 82 inside the hose 8 pushes the block 72 downward, so that the soft hose 8 is connected with the corresponding box body; like Figure 2 and Figure 8 As shown, the vent hole 64 opened on the bottom of the liquid storage tank 61 enables the air intake box 6 to be connected with the liquid storage tank 61. When the hose 8 is connected with the threaded interface 73 on the liquid storage tank 61, the piston cylinder 4 inflates the air into the air intake box 6 under the action of the first piston 43, and the threaded interface 73 on the air intake box 6 is in a closed state. As the air pressure increases, the air in the air intake box 6 flows into the liquid storage tank 61 through the vent hole 64, thereby generating a thrust on the second piston 63. Under the action of the thrust, the second piston 63 moves upward to push the liquid inside the liquid storage tank 61 out, and enters the opening opened in the brush rod 2 and the toothbrush head 21 through the guidance of the hose 8. The liquid is finally sprayed out through the through hole 22 in the cavity 23. The through hole 22 is designed with a certain inclination angle, so that the liquid can be sprayed to the bristle brush head and teeth on the toothbrush head 21 at a certain angle, so as to realize a simple flushing of the teeth during the brushing process. The user can inject clean water or mouthwash into the liquid storage tank 61 through the adapter 81 with the same structure as the hose 8. It should be noted that when the liquid is added to the liquid storage tank 61, the hose 8 needs to be connected to the threaded interface 73 on the air inlet box 6, so that when the liquid is poured into the liquid storage tank 61, the gas in the liquid storage tank 61 can be discharged through the air inlet box 6 and the hose 8; When the hose 8 is connected to the threaded interface 73 on the air intake box 6, the threaded interface 73 on the liquid storage tank 61 is in a closed state. At this time, the air filled into the air intake box 6 by the piston cylinder 4 will be directly ejected from the through hole 22 on the toothbrush head 21 through the hose 8. By adjusting the swing amplitude and angle of the servo motor 3, the brush on the toothbrush head 21 can be blown dry to avoid moisture sticking to the brush and breeding bacteria. At the same time, liquid can remain in the hose 8 and the cavity 23 and cannot be cleaned.

[0024] Example 3: Reference Figure 1-Figure 10 A method for using a toothbrush with a brush head pressure detection device mainly comprises the following steps: S1, take out the toothbrush head 21 and the brush rod 2 and plug the brush rod 2 into the plug-in rod 24; S2. Use the adapter 81 with the same structure as the hose 8 to inject clean water or mouthwash into the liquid storage tank 61. When injecting the liquid, it should be noted that the hose 8 should be connected to the threaded interface 73 on the air inlet box 6; S3, connect the hose 8 to the threaded interface 73 on the liquid storage tank 61, and start the present invention by pressing the switch. When the toothbrush head 21 contacts the teeth, the pressure sensor 52 detects the pressure change, the servo motor 3 drives the toothbrush head 21 to move, and the user performs the toothbrushing operation; S4, after brushing teeth, connect the hose 8 to the threaded interface 73 on the air intake box 6 again, start the cleaning mode, and blow dry and clean the hose 8 and the brush; S5. Fold the device and store it in a dark place.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the present invention can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
