Description

Technical Field

[0001] This invention relates to the field of electric toothbrush technology, and more particularly to an electric toothbrush and its charging base. Background Technology

[0002] An electric toothbrush uses the rapid rotation or vibration of a motor core to generate high-frequency vibrations in the brush head, instantly breaking down toothpaste into fine foam that deeply cleans between teeth, thus achieving the function of cleaning teeth. An electric toothbrush includes a handle and a detachable brush head. The handle contains a drive motor, battery, and control circuit. The charging base is used to provide power to the electric toothbrush. It usually uses inductive or contact charging principles, and connects to the charging interface at the bottom of the handle through electromagnetic induction or metal contacts to convert external power into a suitable voltage to charge the built-in battery.

[0003] Most existing electric toothbrushes have fixed bases that are placed on the washstand. They are powered by AC power via a power cord or by a USB interface. The electric toothbrush and the charging base are usually aligned by magnetic or mechanical clips to ensure charging stability. The whole set of equipment is mainly suitable for daily oral cleaning and maintenance in fixed places such as homes and hotels.

[0004] Current electric toothbrushes are usually equipped with a dedicated charging base and a separate storage box. The two are designed separately. The charging base is fixed to the table and connected to the power source via a cable. The storage box is only used to store and protect the brush body. When carrying it out, users need to put the electric toothbrush in the storage box and store the charging base separately, which leads to redundant luggage and takes up limited space.

[0005] Furthermore, when used in hotels and other outings, the storage box and charging dock are single-function and have a fixed form, making them impossible to assemble or convert. The storage box is only for closed storage; once opened, it is easy to roll off the countertop and takes up space. The charging dock needs to be placed on the countertop, and due to the limited countertop area and hygiene conditions, it is difficult to use stably in small or humid bathroom environments. It also cannot be converted into a stand to adapt to different usage scenarios, making storage and charging inconvenient when used out and about.

[0006] Therefore, an electric toothbrush and its charging base are proposed to solve the above problems. Summary of the Invention

A lower slot is opened on the adjacent side of each rectangular slot. The positioning pin is longitudinally slidably connected to the inner side of the lower slot. The positioning spring is fixedly connected between the lower slot and the outer wall of the positioning pin. Each positioning pin is inserted into the inner side of one of the positioning slots. Hinges are fixedly connected to the upper and lower sides of the side wall of the lower shell relative to the adjustment plate. The hinges are hinged to the adjustment plate. An inclined structure for adjusting the angle of the charger is provided in the placement slot on the upper shell.

[0011] In the above technical solution, a flip groove is further provided on the side wall of the lower shell relative to the hinge plate. The lower groove passes through the front side of the upper shell. A push rod is fixedly connected to the front side of the positioning pin. A storage groove for storing the push rod after flipping is provided on the front side of the lower shell.

[0012] In the above technical solution, the side wall of the adjustment plate is further provided with a guide groove, and the guide rods are all inserted into the inner side of the guide groove, and the guide rods are fixedly connected to the inner side of the rectangular groove.

[0013] In the above technical solution, a pair of upper brackets are fixedly connected to the rear side of the upper shell, and a pair of lower brackets are fixedly connected to the rear side of the lower shell. A groove is provided on the rear side of the lower shell, and a positioning plate is rotatably connected to the inner side of the groove. A positioning bolt is threaded through the side wall of the positioning plate, and a magnet block for adsorbing the positioning bolt is fixedly connected through the inner side of the groove. Both the upper bracket and the lower bracket are made of magnetic material.

[0014] In the above technical solution, the inclined structure further includes an inclined plate, a limiting block, and an insert plate. A pair of limiting blocks are provided, and the limiting blocks are fixedly connected to the inner side of the placement groove. The inclined plate is rotatably connected between the limiting blocks. The insert plate is longitudinally slidably connected to the side wall of the limiting block. An L-shaped tube is fixedly connected to the inner side of the upper shell. A pull rope is threaded through the inner side of the L-shaped tube. One end of the pull rope is fixedly connected to the top of the side wall of the inclined plate. A side plate is fixedly connected to the end of the adjusting plate away from the rectangular groove opening. The other end of the pull rope is fixedly connected to the side wall of the side plate. An elastic sheet is fixedly connected to the side wall of the insert plate.

[0015] In the above technical solution, the top of the charger is provided with a slot, and the inside of the slot is provided with a side groove.

[0016] In the above technical solution, one of the limiting blocks has a circular arc groove through its side wall, and the inclined plate has a round rod fixedly connected to its side wall for insertion into the circular arc groove.

[0017] An electric toothbrush was also disclosed, including a toothbrush body, a magnetic charging port at the bottom of the toothbrush body, and an iron ring fixedly connected to the bottom of the toothbrush body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This invention integrates charging and storage functions by assembling the charger into a carrying case consisting of an upper and lower shell. When traveling, there is no need to carry the charger and storage case separately, effectively reducing luggage volume. Furthermore, through the design of the adjustable structure, the upper and lower shells can be adjusted to an L-shaped flip state and clamped onto the faucet pipe, so that the case is suspended and fixed in the wash area, completely freeing up hotel countertop space and avoiding hygiene hazards and the risk of tipping due to contact with a damp countertop. The toothbrush body can be stably placed on the charger inside the case, which not only achieves continuous power supply for charging as needed, but also forms a vertical draining posture to keep the brush body dry and hygienic, significantly improving portability and user experience in travel scenarios.

[0020] 2. The tilting structure design of this invention enables the charger to flip forward synchronously before the upper and lower shells are adjusted in an L-shape. This achieves linkage adaptation between the box posture and the charger angle, allowing the charger to flip forward. This makes it easy to insert a complete toothbrush with the toothbrush head installed when traveling, without adjusting the box angle or forcibly aligning it. This significantly simplifies the operation steps. The automatic flipping mechanism ensures that the toothbrush insertion direction is consistent with human usage habits when suspended and clamped, improving the convenience of charging and docking and the rationality of human-computer interaction.

[0034] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0036] In actual use, it was found that existing electric toothbrushes are usually equipped with a dedicated charging base and a separate storage box. The two are separate designs. The charging base is fixed to the table and connected to the power source via a wire. The storage box is only used to store and protect the brush body. When carrying it out, users need to put the electric toothbrush in the storage box and store the charging base separately, which leads to redundant luggage and takes up limited space. To solve the above problems, the following structure was invented.

[0037] like Figures 1-2 An electric toothbrush is shown, including a toothbrush body 1, a magnetic charging port 2 at the bottom of the toothbrush body 1, and an iron ring 3 fixedly connected to the bottom of the toothbrush body 1.

[0038] like Figures 2-12 The charging stand shown includes a charger 4, an upper shell 5, and a lower shell 6. The inner sides of both the upper shell 5 and the lower shell 6 are provided with semi-circular grooves 7 for placing the toothbrush body 1. The bottom inner sides of both the upper shell 5 and the lower shell 6 are provided with placement grooves 8 for placing the charger 4. An adjustment structure for adjusting the connection position is provided between the upper shell 5 and the lower shell 6, and a buckle structure for limiting the flipping of the box is provided between the upper shell 5 and the lower shell 6. The buckle structure can fix the upper shell 5 and the lower shell 6 together. This is a mature technology in the prior art and will not be described in detail here.

[0039] The USB charging port of the charger 4 is located at the bottom, which facilitates the connection of the charger 4 to the power source after it is placed inside the upper shell 5 and the lower shell 6. The bottom opening of the placement slot 8 on the upper shell 5 is larger than the bottom size of the charger 4, which facilitates the subsequent flipping of the charger 4 in the placement slot 8. The top of the charger 4 has a charging slot 9 for the bottom of the toothbrush body 1 to sit on. The charging slot 9 has a charging end 10 for inserting the magnetic charging port 2 to charge the toothbrush body 1. The bottom of the charging slot 9 is fixedly connected to a magnetic ring 11. The setting of the iron ring 3 and the magnetic ring 11 ensures that the charger 4 can be firmly attached to the charger 4 after it is flipped, ensuring the stability of the toothbrush body 1 placed in the charger 4. The inner side of the lower shell 6 has a slot 12 for holding the toothbrush head. The slot 12 is designed to facilitate the carrying of the toothbrush head.

[0040] The adjustment structure includes a T-shaped adjustment plate 13, a positioning pin 14, a positioning spring 15, and a guide rod 16. Each adjustment plate 13, positioning pin 14, positioning spring 15, and guide rod 16 is provided in pairs. A pair of rectangular slots are opened on the side wall of the upper shell 5. The adjustment plates 13 are slidably connected to the inside of the rectangular slots. A pair of positioning slots 17 are opened on the side of the adjustment plates 13 that are close to each other. A lower slot 20 is opened on the side of the rectangular slots that are close to each other. The positioning pin 14 is slidably connected to the inside of the lower slot 20 in the longitudinal direction. The positioning spring 15 is fixedly connected between the lower slot 20 and the outer wall of the positioning pin 14. The positioning pin 14 is inserted into the inside of one of the positioning slots 17. The side wall of the lower shell 6 is fixedly connected to the upper and lower sides of the adjustment plate 13. The hinge plate 18 is hinged to the adjustment plate 13. The placement slot 8 on the upper shell 5 is provided with an inclined structure for adjusting the angle of the charger 4.

[0041] A flip groove 19 is provided on the side wall of the lower shell 6 relative to the hinge plate 18. The lower groove 20 is provided through the front side of the upper shell 5. A push rod 21 is fixedly connected to the front side of the positioning pin 14. A storage groove 22 is provided on the front side of the lower shell 6 for storing the push rod 21 after flipping. The storage groove 22 ensures that the upper shell 5 and the lower shell 6 will not be obstructed by the push rod 21 when they are flipped and merged.

[0042] The side wall of the adjusting plate 13 is provided with a guide groove 23, and the guide rods 16 are all inserted into the inside of the guide groove 23. The guide rods 16 are fixedly connected to the inside of the rectangular groove. By setting the guide groove 23 and the guide rods 16, the sliding distance of the adjusting plate 13 can be limited, so as to prevent the adjusting plate 13 from sliding out of the rectangular groove.

[0043] A pair of upper brackets 24 are fixedly connected to the rear side of the upper shell 5, and a pair of lower brackets 25 are fixedly connected to the rear side of the lower shell 6. A groove 26 is provided on the rear side of the lower shell 6. A positioning plate 27 is rotatably connected to the inner side of the groove 26. A positioning bolt 28 is threaded through the side wall of the positioning plate 27. A magnet 29 for adsorbing the positioning bolt 28 is fixedly connected through the inner side of the groove 26. By setting the magnet 29, the positioning bolt 28 and the positioning plate 27 can be adsorbed and fixed, ensuring the stability of the positioning plate 27 in the groove 26 and preventing it from shaking randomly during carrying. Both the upper brackets 24 and the lower brackets 25 are made of magnets.

[0044] When a user needs to carry the toothbrush body 1 when going out, first place the charger 4 in the placement slot 8 of the upper shell 5, then remove the toothbrush head from the toothbrush body 1 and clip the toothbrush head into the slot 12. Next, insert the bottom of the toothbrush body 1 into the charging slot 9, and then clip the entire toothbrush body 1 into the semi-circular slot 7. Then, flip the lower shell 6 over, merge the upper shell 5 and the lower shell 6 together, and fix them in place with the buckle structure to complete the storage.

[0045] When a user brings an electric toothbrush to a hotel and needs to fix the upper shell 5 and lower shell 6 to the faucet, they can first open the upper shell 5 and lower shell 6, then take the toothbrush body 1 out of the upper shell 5, and then push the two push rods 21 towards the middle, causing the positioning pin 14 to move towards the middle and compress the positioning spring 15, thereby causing the positioning pin 14 to move out of the positioning groove 17, thus releasing the sliding restriction on the adjustment plate 13. Then the lower shell 6 can be pulled outward, at which time the adjustment plate 13 will slide in the rectangular groove through the hinge plate 18, and the guide rod 16 will slide in the guide groove 23. When the guide rod 16 moves to the other end of the guide groove 23, it will cause another positioning groove 17 to move to the side of the positioning pin 14. Then the push rod 21 can be released, and the positioning pin 14 will be pushed into the corresponding positioning groove 17 under the elastic force of the positioning spring 15, thereby restricting the sliding position of the adjustment plate 13.

[0046] By pulling the lower shell 6, the distance between the upper shell 5 and the lower shell 6 is increased. Then, the positioning plate 27 on the rear side of the lower shell 6 can be pried out from the groove 26. Before flipping, the upper bracket 24 on the rear side of the upper shell 5 is first attached to the outside of the faucet. Then, the lower shell 6 is flipped backward, which causes the lower bracket 25 to be attached to the outer wall of the faucet. At the same time, the positioning plate 27 is pressed against the outer wall of the faucet. (It should be noted that due to the restriction of the inner wall of the groove 26, the positioning plate 27 can only be rotated 90 degrees within the groove 26. When the lower shell 6 is flipped backward, the positioning plate 27 is pressed against the outer wall of the faucet, and the outer wall of the faucet will press the positioning plate 27 tightly against the inner side of the groove 26.) Then, the positioning bolt 28 is rotated to the side wall of the faucet (the position where the positioning bolt 28 is turned out is opposite the position of the lower bracket 25), which further restricts the position of the upper shell 5 and the lower shell 6 on the faucet, thus completing the installation and fixation of the upper shell 5 and the lower shell 6 on the faucet.

[0047] In summary, the above structural design allows the charger 4 to be assembled into a carrying case consisting of an upper shell 5 and a lower shell 6, integrating charging and storage functions. This eliminates the need to carry the charger 4 and storage case separately when traveling, effectively reducing luggage volume. Furthermore, the adjustable structure allows the upper shell 5 and lower shell 6 to be flipped into an L-shape and clamped onto the faucet pipe, suspending the case in the wash area and freeing up hotel countertop space. This avoids hygiene hazards and the risk of tipping over due to contact with damp surfaces. The toothbrush body 1 can be stably placed on the charger 4 inside the case, providing continuous power for on-demand charging while maintaining a vertical draining posture to keep the brush dry and hygienic. This significantly improves portability and user experience during travel.

[0048] Based on the above embodiments, it was found during use that existing electric toothbrush carrying cases usually separate the brush head from the toothbrush body 1 for storage in order to save space. When the carrying case is used as a stand by a faucet, the toothbrush body 1 must be taken out first to install the brush head before it can be used. After use, it must be disassembled and put back, which is a cumbersome operation. In order to solve the above problems, the above structure has been further improved.

[0049] The inclined structure includes an inclined plate 30, a limiting block 31, and an insert plate 32. A pair of limiting blocks 31 are provided, and the limiting blocks 31 are fixedly connected to the inside of the placement groove 8. The inclined plate 30 is rotatably connected between the limiting blocks 31. The insert plate 32 is longitudinally slidably connected to the side wall of the limiting block 31. An L-shaped tube 33 is fixedly connected to the inside of the upper shell 5. A pull rope 34 is passed through the inside of the L-shaped tube 33. One end of the pull rope 34 is fixedly connected to the top of the side wall of the inclined plate 30. A side plate 35 is fixedly connected to the end of the adjusting plate 13 away from the rectangular groove opening. The other end of the pull rope 34 is fixedly connected to the side wall of the side plate 35. An elastic piece 36 is fixedly connected to the side wall of the insert plate 32.

[0050] The charger 4 has a slot 37 at the top and a side slot 38 inside the slot 37.

[0051] One of the limiting blocks 31 has a circular arc groove 39 through its side wall, and a round rod 40 for inserting into the inside of the circular arc groove 39 is fixedly connected to the side wall of the inclined plate 30. The circular arc groove 39 and the round rod 40 can limit the flipping angle of the inclined plate 30. It should be noted that when the adjusting plate 13 extends and releases the restriction on the inclined plate 30, the charging 4 can be pulled out, which will cause the insert plate 32 and the inclined plate 30 to flip forward around the hinge, thereby causing the charging 4 to flip forward by 10 degrees. This ensures that the toothbrush body 1 with the toothbrush head is not obstructed by the upper shell 5 when inserted into the charging 4.

[0052] Next, install the charger 4 in the placement slot 8. First, place the charger 4 in the placement slot 8, and then push the plug plate 32 down to insert the plug plate 32 into the slot 37 of the charger 4. During the insertion process, the inner wall of the slot 37 will compress the elastic piece 36 and deform it. Then, when the plug plate 32 is fully inserted and the elastic piece 36 moves to the side slot 38, the compression on the elastic piece 36 will be released. Then, under the elastic force of the elastic piece 36 itself, it will reset and be stuck in the side slot 38, thus realizing the connection between the plug plate 32 and the charger 4.

[0053] During the process of releasing the limiting position of the adjustment plate 13 and pulling out the adjustment plate 13, the side plate 35 will move together, thereby releasing the pull on the pull rope 34. Then the charger 4 can be pried open, which will move the plug plate 32 and the tilt plate 30, causing the tilt plate 30 to flip forward around the hinge. At the same time, the round rod 40 will slide in the arc groove 39. At this time, the round rod 40 is inserted in the arc groove 39, which will limit the forward tilt angle of the charger 4, thus completing the adjustment. The toothbrush body 1 can then be installed with the toothbrush head and inserted into the charging slot 9. If charging is required, the data cable can be plugged into the USB hole at the bottom of the charger 4 and connected to the power socket.

[0054] Finally, when the adjustment plate 13 is pushed back into position, it will drive the side plate 35 to reset, thereby pulling the pull rope 34 and causing the tilt plate 30 to flip backward. At the same time, the plug plate 32 drives the charger 4 to flip backward until the round rod 40 moves to the other side of the arc groove 39, and then it will automatically reset.

[0055] In summary, the above structural design allows the charger 4 to flip forward synchronously before the upper shell 5 and lower shell 6 are adjusted in an L-shape. This achieves a synchronized adaptation between the box posture and the charger 4 angle, enabling the charger 4 to flip forward. This facilitates the insertion of a fully fitted toothbrush with the toothbrush head installed during travel, eliminating the need to adjust the box angle or force alignment. This significantly simplifies the operation. The automatic flipping mechanism ensures that the toothbrush insertion direction is consistent with human usage habits when suspended in the air, improving the convenience of charging and the rationality of human-computer interaction.
