Description

Technical Field

[0001] This utility model relates to the field of oral hygiene technology, and in particular to a toothbrush with plaque detection function. Background Technology

[0002] Toothbrushes with plaque detection function are crossover products that combine oral cleaning with intelligent detection. They have the basic cleaning properties of ordinary toothbrushes and the advantage of plaque visualization. They are practical tools for daily oral care and health management. Most of them are electric toothbrushes, and some are equipped with manual adapters. The core highlight is that they can intuitively present the distribution of plaque on the tooth surface through exclusive detection technology, helping users to accurately identify cleaning blind spots and avoid the omissions caused by traditional brushing.

[0003] Toothbrushes with plaque detection functions are oral care products that combine cleaning and plaque monitoring. Their working principles mainly fall into two categories. One type uses a specific substance to react with plaque, revealing plaque that is normally invisible to the naked eye and helping users visually identify cleaning blind spots. The other type uses radiation to illuminate the tooth surface, collecting the reflected light and fluorescence, converting the signals, and analyzing them to obtain plaque-related data. Some products also combine brushing cleanliness with proprietary algorithms to provide dynamic plaque reminders and even connect with an app to generate brushing reports, helping users understand their oral plaque status and improve the effectiveness of cleaning.

[0004] In existing technologies, brush heads are exposed to the air for a long time, making them prone to dust, bacteria, and moisture from the washbasin. During transportation or storage, the brush head bristles are easily deformed and worn due to compression, and the sensitive structures for detection are damaged by collisions, shortening the product's lifespan. Therefore, a toothbrush with plaque detection function is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a toothbrush with plaque detection function, which aims to improve the problem of easy contamination by dust, bacteria and water vapor from the washbasin in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A toothbrush with plaque detection function includes a handle, a control console fixedly connected to the outer wall of the handle, a connecting rod rotatably connected to the top of the handle, a brush head fixedly connected to the top of the connecting rod, a protective mechanism installed on the outer wall of the brush head, and an adjustment mechanism installed inside the handle.

[0008] The protective mechanism includes a protective shell, the outer wall of which is detachably connected to the outer wall of the brush head, a positioning rod fixedly connected inside the protective shell, a sliding ring slidably connected to the outer wall of the positioning rod, a guide rod fixedly connected to the outer wall of the brush head, a spring sleeved on the outer wall of the guide rod, an inclined block slidably connected to the outer wall of the guide rod, and an ejection assembly slidably connected to the inner wall of the brush head.

[0009] As a further description of the above technical solution:

[0010] The ejection assembly includes a guide rod 2, the outer wall of the guide rod 2 is slidably connected to the inner wall of the brush head, a spring 2 is sleeved on the outer wall of the guide rod 2, a contact plate is fixedly connected to the top end of the guide rod 2, a support plate is fixedly connected to the inner wall of the brush head, and a sliding rod is connected to the outer wall of the contact plate.

[0011] As a further description of the above technical solution:

[0012] The adjustment mechanism includes an electric push rod, the outer wall of which is fixedly connected to the inner wall of the handle, a sliding plate fixedly connected to the drive end of the electric push rod, a fixed rod fixedly connected to the outer wall of the sliding plate, a connecting rod two fixedly connected to the inner wall of the first connecting rod, and a rotating plate fixedly connected to the outer wall of the second connecting rod.

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixed to the outer wall of the brush head, and the other end of the spring is fixedly connected to the outer wall of the inclined block.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the positioning rod is slidably connected to the inner wall of the brush head, and the outer wall of the inclined block is in contact with the outer wall of the sliding ring;

[0017] As a further description of the above technical solution:

[0018] The bottom end of the positioning rod contacts the top end of the contact plate, and the outer wall of the sliding rod is slidably connected to the inner wall of the support plate.

[0019] As a further description of the above technical solution:

[0020] One end of the second spring is fixedly connected to the inner wall of the brush head, and the other end of the second spring is fixedly connected to the outer wall of the contact plate.

[0022] The outer wall of the sliding plate is slidably connected to the inner wall of the handle, and the outer wall of the fixed rod is slidably connected to the inner wall of the rotating plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, pressing the protective shell causes the positioning rod to press down on the contact plate, and the first spring returns to its original position, pushing the inclined block to push the sliding ring. After the sliding ring slides into the positioning rod groove, the inclined block separates from it, completing the unlocking process. The second spring pushes the contact plate to pop out the protective shell, allowing the brush head to be retrieved. This effectively isolates dust, moisture, and bacteria from the washbasin, preventing the plaque detection components, such as the sensing area and the light-emitting unit, from being covered by dirt, thus ensuring detection accuracy and hygiene.

[0025] 2. In this utility model, the control console activates the electric push rod, whose drive end pushes the sliding plate to move the fixed rod. The fixed rod pushes the rotating plate to rotate around the second connecting rod, which in turn drives the first connecting rod to rotate, so that the brush head is adjusted to the appropriate angle to meet the cleaning needs of different parts of the oral cavity. By flexibly adjusting the angle, it can easily adapt to the dead areas in the oral cavity that are difficult to reach by traditional brush heads, such as the inside of the molars, wisdom teeth, and interdental spaces.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0036] A toothbrush with plaque detection function, refer to Figure 1 , Figure 4 and Figure 5 The device includes a handle 1, a control console 2 fixedly connected to the outer wall of the handle 1, the handle 1 providing a stable mounting support for the control console 2 to ensure that the control console 2 does not wobble during operation, a connecting rod 3 rotatably connected to the top of the handle 1, the handle 1 providing a fulcrum for the connecting rod 3 to ensure that the connecting rod 3 can be flexibly adjusted in angle, a brush head 5 fixedly connected to the top of the connecting rod 3, the connecting rod 3 providing a mounting base for the brush head 5 and driving the brush head 5 to adjust its position and angle synchronously, a protective mechanism 4 installed on the outer wall of the brush head 5, the brush head 5 providing an installation adapter structure for the protective mechanism 4 so that the protective mechanism 4 can accurately cover the brush head 5, and an adjustment mechanism 6 installed inside the handle 1, the handle 1 providing a closed installation space for the adjustment mechanism 6 to protect the internal components of the adjustment mechanism 6 from external interference;

[0037] The protective mechanism 4 includes a protective shell 41. The outer wall of the protective shell 41 is detachably connected to the outer wall of the brush head 5. A positioning rod 42 is fixedly connected inside the protective shell 41, providing fixed support for the positioning rod 42 to ensure accurate positioning. A sliding ring 43 is slidably connected to the outer wall of the positioning rod 42, providing sliding guidance for the sliding ring 43, allowing the sliding ring 43 to move flexibly along the positioning rod 42. A guide rod 44 is fixedly connected to the outer wall of the brush head 5, providing a fixed mounting point for the guide rod 44 to ensure stable positioning. A spring 45 is sleeved on the outer wall of the guide rod 44, providing installation support and deformation guidance for the spring 45 to prevent displacement when the spring 45 is compressed or reset. A wedge 46 is slidably connected to the outer wall of the guide rod 44, limiting the sliding path of the wedge 46 so that the wedge 46 can only move along the direction of the guide rod. An ejection assembly 47 is slidably connected to the inner wall of the brush head 5. The ejector assembly 47 provides installation space and sliding guidance to ensure stable operation. The ejector assembly 47 includes a second guide rod 471. The outer wall of the second guide rod 471 is slidably connected to the inner wall of the brush head 5. The brush head 5 provides sliding support for the second guide rod 471 and limits the movement direction of the second guide rod 471. A second spring 472 is sleeved on the outer wall of the second guide rod 471. The second guide rod 471 provides deformation guidance for the second spring 472 to prevent the second spring 472 from twisting and failing. A contact plate 473 is fixedly connected to the top of the second guide rod 471. The second guide rod 471 provides fixed support for the contact plate 473 and drives the contact plate 473 to rise and fall synchronously. A support plate 474 is fixedly connected to the inner wall of the brush head 5. The brush head 5 provides a fixed installation base for the support plate 474 to ensure the stable position of the support plate 474. A sliding rod 475 is connected to the outer wall of the contact plate 473. The contact plate 473 drives the sliding rod 475 to move synchronously and transmits its own force and movement to the sliding rod 475.

[0038] Specifically, the toothbrush uses the handle 1 as its basic carrier, providing mounting support for the control panel 2, adjustment mechanism 6, etc. The control panel 2 enables functional operation and data feedback. The adjustment mechanism 6 is installed within the internal space of the handle 1 and can flexibly adjust the angle of the connecting rod 3 and brush head 5 through the transmission component to adapt to different cleaning needs. The protective mechanism 4 on the outer wall of the brush head 5 is stably assembled through the cooperation of the positioning rod 42, sliding ring 43, and inclined block 46, which can protect the brush head 5. The ejection component 47 uses spring force to assist the protective shell 41 in easy opening and closing. All components work together in mutual support and transmission to ensure the practicality and convenience of the toothbrush.

[0039] Reference Figure 2 , Figure 6 and Figure 7The adjustment mechanism 6 includes an electric push rod 61. The outer wall of the electric push rod 61 is fixedly connected to the inner wall of the handle 1. The electric push rod 61 obtains stable support for the handle 1 through the fixed outer wall, avoiding shaking and deviation during operation. A sliding plate 62 is fixedly connected to the drive end of the electric push rod 61. The drive end of the electric push rod 61 drives the sliding plate 62 to slide linearly, converting its own extension and retraction power into the displacement of the sliding plate 62. A fixed rod 63 is fixedly connected to the outer wall of the sliding plate 62. The sliding plate 62 provides a firm mounting carrier for the fixed rod 63 and drives the fixed rod 63 to move synchronously. A connecting rod 64 is fixedly connected to the inner wall of the connecting rod 1 3. The connecting rod 1 3 provides an internal mounting fixing point for the connecting rod 2 64, so that the connecting rod 2 64 forms a stable linkage with itself. A rotating plate 65 is fixedly connected to the outer wall of the connecting rod 2 64. The connecting rod 2 64 provides fixed support and a rotation axis for the rotating plate 65, ensuring that the rotating plate 65 rotates stably around it.

[0040] Specifically, the adjustment mechanism 6 uses an electric push rod 61 as its core power source. It is stably supported by the inner wall of the handle 1, and the drive end causes the sliding plate 62 to slide linearly, converting the extension and retraction force into the displacement of the sliding plate 62. The sliding plate 62 drives the fixed rod 63 to move stepwise. Through the cooperation of the fixed rod 63 and the rotating plate 65, the linear motion is converted into the rotational force of the rotating plate 65. The rotating plate 65 obtains a stable rotation axis based on the second connecting rod 64, which forms a stable linkage with the first connecting rod 3. Ultimately, this drives the first connecting rod 3 and the brush head 5 to flexibly adjust their angles, achieving precise cleaning posture adaptation.

[0041] Reference Figure 3 , Figure 5 and Figure 7One end of spring 45 is fixed to the outer wall of brush head 5. Spring 45 obtains stable support for brush head 5 through this fixation, ensuring controllable deformation direction. The other end of spring 45 is fixedly connected to the outer wall of inclined block 46. Spring 45 is linked to inclined block 46 through this fixation, converting elastic potential energy into pushing or pulling force of inclined block 46. The outer wall of positioning rod 42 is slidably connected to the inner wall of brush head 5. Positioning rod 42 obtains guidance from the inner wall of brush head 5 through its sliding outer wall, ensuring accurate movement trajectory. The outer wall of inclined block 46 contacts the outer wall of sliding ring 43. Inclined block 46 transmits pressure or pushing force to sliding ring 43 through this contact, achieving limiting or releasing of sliding ring 43. The bottom end of positioning rod 42 contacts the top end of contact plate 473. Positioning rod 42 transmits pressure to contact plate 473 through this contact, triggering the ejection assembly 47. The sliding rod 475 is slidably connected to the inner wall of the support plate 474. The sliding rod 475 is guided by the support plate 474 through the sliding of the outer wall, ensuring that its movement is stable and does not deviate. One end of the second spring 472 is fixedly connected to the inner wall of the brush head 5. The second spring 472 is fixedly connected to the inner wall of the brush head 5 through the fixed end, ensuring that it will not be misaligned when deformed. The other end of the second spring 472 is fixedly connected to the outer wall of the contact plate 473. The second spring 472 is fixedly linked with the contact plate 473 through the other end, converting the elastic potential energy into the pushing or pulling force of the contact plate 473. The outer wall of the sliding plate 62 is slidably connected to the inner wall of the handle 1. The sliding plate 62 is guided by the inner wall of the handle 1 through the sliding of the outer wall, ensuring that the linear motion trajectory is accurate. The outer wall of the fixed rod 63 is slidably connected to the inner wall of the rotating plate 65. The fixed rod 63 transmits the pushing or pulling force to the rotating plate 65 through the sliding of the outer wall, driving the rotating plate 65 to rotate.

[0042] Specifically, spring 45 and spring 472 are stably supported by the brush head 5, and convert elastic potential energy into pushing or pulling force through linkage with the inclined block 46 and the contact plate 473, providing power for the action of the protective mechanism 4; the positioning rod 42, sliding rod 475 and other components are guided by the brush head 5 or the support plate 474 to ensure accurate movement trajectory. In the protective mechanism 4, the inclined block 46 achieves limit or release through contact with the sliding ring 43, and the positioning rod 42 causes the push-out component 47 to move; in the adjustment mechanism 6, the sliding plate 62 drives the fixed rod 63 to move by the guide of the handle 1, and transmits power by pushing the rotating plate 65 to rotate. All components work together to ensure the stable operation of the mechanism.

[0043] The implementation principle of this application embodiment is as follows: Before use, the angle of the brush head 5 is adjusted by the adjustment mechanism 6: The control console 2 starts the electric push rod 61, and its driving end pushes the sliding plate 62 to slide along the inner wall of the handle 1. The sliding plate 62 drives the fixed rod 63 to move. The fixed rod 63 slides on the inner wall of the rotating plate 65, pushing the rotating plate 65 to rotate around the second connecting rod 64, thereby driving the first connecting rod 3 to adjust the angle of the brush head 5 to adapt to different oral cleaning needs.

[0044] When brush head 5 is used, pressing the protective shell 41 triggers unlocking. With the protective shell 41 fixed, the bottom end of the positioning rod 42 presses against the contact plate 473, compressing the second spring 472. The inclined block 46 clamps the positioning rod 42 and compresses the first spring 45. When the protective shell 41 is pressed, the positioning rod 42 presses down on the contact plate 473. The contact plate 473 drives the sliding rod 475 to slide along the support plate 474. At the same time, the sliding ring 43 squeezes the inclined block 46. The inclined block 46 slides along the outer wall of the sliding ring 43, squeezing the sliding ring 43. The first spring 45 resets and pushes the inclined block 46 to push the sliding ring 43, causing the positioning rod 42 to move the protective shell 41. At this time, the operator moves the protective shell 41 upward, and the inclined block 46 drives the sliding ring 43 downward. After the sliding ring 43 slides into the groove opened by the positioning rod 42, the inclined block 46 separates from the positioning rod 42, completing the unlocking. Spring 472 pushes the contact plate 473 upward, popping out the protective shell 41, which can then be removed to use the brush head 5.

[0045] Before use, adjust the angle of the brush head 5 using the adjustment mechanism 6. Then, operate the control panel 2 to activate the electric push rod 61 inside the handle 1. The drive end of the push rod 61 pushes the sliding plate 62 to slide along the inner wall of the handle 1. The sliding plate 62 drives the fixed rod 63 to move. The fixed rod 63 slides on the inner wall of the rotating plate 65, pushing the rotating plate 65 to rotate around the second connecting rod 64, which in turn drives the first connecting rod 3 to rotate, so that the brush head 5 is adjusted to an angle suitable for oral cleaning to meet the cleaning needs of different parts of the mouth.
