Description

Technical Field

[0001] The utility model belongs to the technical field of electric toothbrushes and relates to an electric toothbrush with a decorative ring mounting structure. Background Art

[0002] The electric toothbrush uses the rapid rotation or vibration of the motor core to make the brush head vibrate at a high frequency, instantly breaking down the toothpaste into fine foam and deeply cleaning the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the oral cavity and have a massage effect on the gum tissue.

[0003] Chinese patent CN218916225U discloses an electric toothbrush with an easy-to-replace brush head. The electric toothbrush is designed with an anti-skid pad, which can prevent the electric toothbrush body from slipping when in use, thereby improving its safety. At the same time, it can also avoid wear caused by direct contact with the outer shell of the electric toothbrush body. At the same time, the anti-skid pad can be easily disassembled, making it easy to replace and use.

[0004] When disassembling the brush head of the electric toothbrush, it is necessary to first buckle the buckle groove, and then pull the pull block horizontally. The pull block drives the connecting rod to move horizontally, and the connecting rod drives the second magnet to move. The second magnet drives the guide block to slide along the guide groove, so that the second magnet is separated from the first magnet. At the same time, the pull block drives the connecting rod and the protrusion to move horizontally, so that the protrusion is separated from the groove on the connecting head, and then the brush head is moved upward, so that the brush head drives the connecting head to move and separate from the electric toothbrush body, and the brush head can be disassembled. Therefore, the pull block used to connect the brush head and the electric toothbrush body is a separate structure. After disassembly, the pull block needs to be placed separately. Due to the small structure of the pull block, it is easy to fall and be lost when taking it. Moreover, after the pull block is used to fix the brush head and the electric toothbrush body, the pull block is located outside the connection between the brush head and the electric toothbrush body, so that there are two protruding parts on the brush head, which will contact the oral cavity when brushing teeth, reducing the comfort of brushing teeth.

[0032] A groove 16 is provided at the top of the upper end 5, and two limit rotating shafts 11 are rotatably connected inside the groove 16. The two limit rotating shafts 11 are arranged up and down, and the axes of the two limit rotating shafts 11 are on the same vertical plane. A push plate 10 is slidably arranged between the two limit rotating shafts 11.

[0033] The bottom of the brush head 6 is fixedly connected with a connecting plate 7, and a transmission assembly is arranged inside the groove 16, and the transmission assembly cooperates with the connecting plate 7. The transmission assembly drives the push plate 10 to slide horizontally between the two limit rotating shafts 11, and the push plate 10 abuts against the connecting plate 7.

[0034] The transmission assembly includes a seesaw 8, which is rotatably connected to the inside of the groove 16, and the two limit shafts 11 are both located above the seesaw 8. A connecting rod 9 is hinged between the end of the push plate 10 and the end of the seesaw 8, and the connecting plate 7 is movably arranged on the top of the other end of the seesaw 8.

[0035] The top of the upper end 5 is movably provided with a brush head 6. The bottom of the brush head 6 is fixedly connected with a connecting plate 7, and the connecting plate 7 is movably provided at the end of the rocker 8. The bottom of the rocker 8 away from the connecting plate 7 is fixedly connected with a counterweight 15.

[0036] One end of the connecting rod 9 hinged to the rocker plate 8 is located at the end of the rocker plate 8 away from the connecting plate 7, and one end of the connecting rod 9 hinged to the push plate 10 is located at the end of the push plate 10 away from the connecting plate 7.

[0039] The second magnet 14 is movably disposed on the top of the first magnet 13 , and the magnetism of the bottom end of the second magnet 14 is different from the magnetism of the top end of the first magnet 13 .

[0040] Working principle:

[0041] When in use, the anti-slip cover 2 is put on the bottom end of the lower end portion 1, and the anti-slip cover 2 is pushed upward to squeeze the first clamping block 3, and the anti-slip cover 2 is rotated until the first clamping blocks 3 are respectively clamped in the corresponding first clamping grooves.

[0042] Move the upper end 5 to the top of the lower end 1, and put the decorative ring 4 on the protrusion on the top of the lower end 1 to squeeze the second clamping block 12. Rotate the decorative ring 4 until the second clamping blocks 12 are respectively clamped in the corresponding second clamping grooves.

[0043] Move the brush head 6 to the top of the upper end portion 5, so that the connecting plate 7 is located at the top of the upper end portion 5, and push the brush head 6 downward. Make the connecting plate 7 pass through the top of the upper end portion 5 and slide downward in the groove 16. The second magnet 14 will slide toward the top of the first magnet 13.

[0044] The connecting plate 7 will first move to the top of the seesaw 8 and push the seesaw 8 downward, so that one end of the seesaw 8 in contact with the connecting plate 7 will rotate downward, and the other end of the seesaw 8 will tilt upward, and the counterweight 15 will move upward. At this time, due to the gravity of the counterweight 15, the seesaw 8 will be pulled downward, so that the seesaw 8 at the connecting plate 7 has an upward force on the connecting plate 7.

[0045] The upwardly tilted end of the seesaw 8 pushes the connecting rod 9 to rotate, so that the other end of the connecting rod 9 pushes the push plate 10 to slide between the two limit rotating shafts 11 to the side close to the connecting plate 7. When the push plate 10 slides, the two limit rotating shafts 11 rotate to reduce wear.

[0046] When the second magnet 14 slides to the top of the first magnet 13, due to magnetic attraction, the second magnet 14 is fixed on the top of the first magnet 13. At the same time, the rubber pad at one end of the push plate 10 just abuts against one side of the connecting plate 7, fixes the connecting plate 7, and fixes the brush head 6 on the top of the upper end 5.

[0047] The electric toothbrush is used by holding the anti-slip cover 2.

[0048] When the brush head 6 needs to be replaced, the brush head 6 is pulled upward, the connecting plate 7 overcomes the friction of the rubber pad and slides upward, and the second magnet 14 gradually moves upward away from the first magnet 13, so that the connecting plate 7 slides upward on the top of one end of the seesaw 8.

[0049] When the connecting plate 7 slides upward in the groove 16 , due to the gravity of the counterweight 15 , the counterweight 15 pulls one end of the rocker 8 to rotate downward, so that the other end of the rocker 8 continues to abut against the bottom of the connecting plate 7 .

[0050] The rocker plate 8 pulls the push plate 10 toward the side away from the connecting plate 7 through the connecting rod 9 , and the push plate 10 slides between the two limit rotating shafts 11 , so that the rubber pad gradually leaves the connecting plate 7 .

[0051] When the bottom end of the counterweight 15 is located at the bottom surface of the groove 16, the counterweight 15 is fixed, the rocker 8 stops rotating, and the push plate 10 stops sliding. The connecting plate 7 continues to slide upward, and the connecting plate 7 can be removed from the upper end 5. The brush head 6 is disassembled.

[0052] When removing the anti-slip cover 2, push the anti-slip cover 2 downward to squeeze the first clamping block 3 so that the first clamping block 3 leaves the first clamping groove until the anti-slip cover 2 slides out from the lower end 1.

[0053] When removing the upper end portion 5, the upper end portion 5 is pulled upward to drive the decorative ring 4 to move upward, and the second clamping block 12 is squeezed to make the second clamping block 12 leave the second clamping groove, until the decorative ring 4 is removed from the protrusion on the top of the lower end portion 1.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
