Abstract
Description
Technical Field
[0001] The present application relates to the field of toothbrushes, and in particular to an environmentally friendly toothbrush with a replaceable brush head. Background Art
[0002] At present, toothbrushes are the most commonly used oral cleaning tools in daily life, and they are also the most effective cleaning tools. However, due to the different cleaning parts and the changes in the shape of the oral cavity caused by age changes, there are different requirements for the size and shape of the toothbrush head. For example, for the chewing teeth deep in the mouth, due to the small space, a small-sized brush head is needed to reach the cleaning position, while a large-sized brush head is needed for the front of the mouth to increase the cleaning efficiency. For young children, due to the very fast development process and the rapid changes in the oral cavity, the brush head needs to be adjusted in time according to the oral development status.
[0003] Since toothbrush heads will wear out and breed bacteria after long-term use, toothbrushes basically need to be replaced every few months. Currently, toothbrush heads are usually non-replaceable and need to be replaced as a whole. The toothbrush handle takes up most of the overall material. Replacing the entire toothbrush just to replace the brush head causes a lot of waste and is not conducive to energy conservation and environmental protection. Utility Model Content

[0027] The brush head 300 is provided with a card slot 301; the card connection mechanism 500 includes a spring piece 510 and a card block 530, one end of the spring piece 510 is fixedly connected to the hand-held part 100, and the other end of the spring piece 510 is fixedly connected to the card block 530, and the card block 530 is engaged with the card slot 301.
[0028] In a preferred embodiment of the present invention, a rubber sleeve is provided on the outer surface of the hand-held portion 100, and anti-slip grooves are provided on the surface of the rubber sleeve, so as to facilitate stable hand-holding and prevent detachment during use.
[0029] A base 150 is provided at one end of the handheld part 100 away from the brush head 300, and a rubber suction cup is provided on the lower surface of the base 150. The outer diameter of the rubber suction cup is not larger than the diameter of the base 150. By installing the base 150 at the lower end of the handheld part 100, the entire device can be placed vertically, and the additional rubber suction cup is further attracted to the contact surface, so that it can stand upright when placed.
[0030] In a preferred embodiment of the present invention, the spring piece 510 is fixed at the end of the hand-held part 100, and a plug-in slot 310 is provided on the back of the brush head 300. One end of the spring piece 510 is inserted into the plug-in slot 310, and the card slot 301 is provided on the inner wall of the plug-in slot 310. By inserting the spring piece into the plug-in slot 310, the card block 530 is engaged with the card slot 301 to achieve stable locking.
[0031] In a preferred embodiment of the present invention, the hand-held part 100 is slidably connected to a limiting block 130, one end of the limiting block 130 is cooperatively inserted into the insertion slot 310, and a protrusion 131 is provided at one end of the limiting block 130, and the protrusion 131 abuts against the inner wall of the spring piece 510. By the additional protrusion 131 abutting against the inner wall of the spring piece 510, the block 530 is prevented from separating from the slot 301, and the brush head 300 can be effectively fixed to one end of the hand-held part 100 to prevent it from falling off.
[0032] In a preferred embodiment of the utility model, the hand-held part 100 is hollowly provided with a slide groove, and a connecting rod 110 slides through the slide groove, one end of the connecting rod 110 is fixedly connected to the limit block 130, and the other end of the connecting rod 110 is fixedly connected to the end base 150.
[0033] In a preferred embodiment of the present invention, a movable space is reserved between the upper end of the base 150 and the lower end of the hand-held part 100, and a bellows 170 is provided in the movable space. By providing the bellows 170, the transition between the lower end of the hand-held part 100 and the base 150 is made beautiful, and the hollow slide groove of the hand-held part 100 is effectively isolated to prevent stains and impurities from entering.
[0034] In a preferred embodiment of the present invention, the upper end of the bellows 170 is sealed and connected to the lower end of the handheld part 100 , and the lower end of the bellows 170 is sleeved on the surface of the base 150 .
[0035] In a preferred embodiment of the present invention, a receiving cavity is provided at the lower end of the handheld part 100, and the upper end of the base 150 is slidably inserted into the receiving cavity. A compression spring 103 is provided in the receiving cavity, and the lower end of the compression spring 103 is connected to the upper end of the base 150;
[0036] Under the elastic force of the compression spring 103, the base 150 is pushed downward, so that the base 150 is pulled to the connecting rod 110 to drive the upper limit block 130, so that the protrusion 131 at the end of the limit block 130 conflicts with the spring 510; when the brush head 300 needs to be replaced, the handheld part 100 is pressed downward by hand, so that the base 150 compresses the compression spring 103 while pushing the protrusion 131 to separate from the spring 510, which is convenient for unlocking and replacing the brush head 300.
[0037] The working principle of the environmentally friendly toothbrush with replaceable brush head is as follows: when in use, the spring piece 510 is fixedly connected to the hand-held part 100, and the clamping block 530 fixed at one end of the spring piece 510 is engaged with the clamping groove 301 provided on the brush head 300. The clamping mechanism provided at the connection between the hand-held part 100 and the brush head 300 is used to connect the brush head 300 to the end of the hand-held part 100 and limit the rotation and slippage of the brush head 300 at the connection; it is convenient for disassembly and replacement of the brush head 300; by equipping a handle with multiple brush heads, only the brush heads need to be replaced, and the production capacity is invested in the manufacture of brush heads, which reduces the use of production raw materials, saves costs, reduces the consumption of manpower and material resources, and the price of a single brush head purchased by users is also reduced accordingly, which can effectively reduce the production cost and use cost.
