Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of oral care equipment, in particular to an oral cleaning and care device. Background Art
[0002] Traditional oral cleaning devices mostly adopt a fixed structural design. When cleaning the inside and outside of the teeth, there are often problems such as a single water flow impact direction and unadjustable flushing force. In the existing technology, although some devices control the water flow by manually adjusting the valve, they cannot dynamically adjust the water flow impact effect according to the user's bite action, resulting in a balance between cleaning efficiency and comfort. In addition, the upper and lower cleaning components of traditional cleaning devices have a fixed spacing, which makes it difficult to adapt to the differences in dental arch width of different users, limiting the versatility of the device. In terms of mechanical structure, most cleaning devices rely on an independent drive mechanism to realize the movement of the cleaning brush. The structure is complex and the maintenance cost is high. It is also difficult to achieve efficient removal of impurities on the surface of the teeth by simply relying on the reciprocating motion of the brush combined with fixed water flow flushing. Summary of the Invention
[0003] In view of the deficiencies in the prior art, the present invention discloses an oral cleaning and care device to solve the problems raised in the above background technology.

At this time, the first drainage hole and the second drainage hole in the closed state are offset and moved to penetrate the inside of the flushing chamber. At this time, the water in the flushing chamber rushes out from the gap opened by the first drainage hole and the second drainage hole, and rinses the side walls of the teeth, and the water flows out from both sides of the cleaning rack.
[0005] Preferably, a spring is provided on the sliding rod between the sliding hole and the bite plate, and the bite plate held by the teeth is reset by the spring after the bite force disappears. At this time, the U-shaped plate will also be reset together. Through continuous biting and resetting, the gap area flowing through the first drainage hole and the second drainage hole changes in real time, thereby changing the impact force of the water flowing out of the flushing chamber.
[0006] Preferably, the inner side walls of the first cleaning rack and the second cleaning rack are respectively provided with a number of cleaning bristles, which cooperate with the spring to engage, approach and release the bite plate to reset it. The cleaning bristles will clean the inner and outer walls of the teeth up and down during the upper and lower biting process of the teeth, and cooperate with water flushing to realize the cleaning operation of impurities on the surface of the teeth.
[0007] Preferably, both side walls of the lower ends of the first cleaning rack and the second cleaning rack are provided with limiting bars respectively, and the limiting bars are located on the upper side of the bite plate, and the rebound height of the bite plate is limited by the limiting bars.

A locking strip is provided around the outer end surface of the connecting sleeve, and a cylinder is provided on one side of the adjusting ring. By moving the adjusting ring, the cylinder is moved to the position of the locking strip, and the two cooperate with each other so that the locking strip tightens the connecting rod, thereby adjusting the distance between the first cleaning rack and the second cleaning rack.
[0009] Preferably, the inner wall surface of the adjustment ring is provided with a first thread structure, and the outer wall of the connecting sleeve is correspondingly provided with a second thread structure, and the first thread structure and the second thread structure rotate in cooperation with each other.
[0010] Preferably, the inner wall of the cylinder is provided with an inclined surface, and the locking strip is squeezed by the inclined surface.
[0011] Preferably, the outer wall of the connecting rod is provided with a raised mark, and the telescopic length of the connecting rod and the connecting sleeve on both sides can be judged by the raised mark.
[0012] Preferably, the first cleaning rack and the second cleaning rack are respectively provided with water inlet interfaces, and the water inlet interfaces are connected to an external water pump through a provided water collecting joint, and water is transported to the inside of the flushing cavity through the water pump.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, through the mechanical linkage between bite force and U-shaped plate displacement, the user's natural bite action is converted into a dynamic adjustment signal of water flow impact force, realizing the intelligent response of "bite enhancement-relaxation attenuation", which not only meets the deep cleaning needs, but also avoids the mechanical damage to the gums caused by continuous high-pressure water flow.
[0014] 2. In the present invention, the limitation of a single cleaning method is broken through the real-time coordination between the mechanical scraping of the bending and deformation of the cleaning soft bristles and the hydraulic flushing of the variable water flow channel. The mechanical stripping of dental plaque and the hydraulic flushing of gap residues are achieved simultaneously during the occlusal stage, and it switches to gentle flushing during the relaxation stage, taking into account both cleaning efficiency and soft tissue protection.
[0015] 3. In the present invention, the stepless adjustment mechanism of the connecting component is combined with the visual identification system to quickly adapt to different dental arch widths, making the device universal, operationally tolerant and comfortable to use.

[0018] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0019] Example: Figure 1-Figure 7 As shown, the present invention provides an oral cleaning and care device, comprising a first cleaning rack 1, a second cleaning rack 2 and a bite plate 3; Among them, the open ends of the first cleaning rack 1 and the second cleaning rack 2 face outward, and the upper and lower teeth of the user are wrapped through the open ends to form a semi-closed cleaning cavity, which effectively prevents the flushing water from overflowing; the bottoms of the first cleaning rack 1 and the second cleaning rack 2 are connected by a connecting component provided, wherein a flushing cavity 5 is provided inside the cleaning rack, and the first cleaning rack 1 and the second cleaning rack 2 are respectively provided with a water inlet interface 503, and the water inlet interface 503 is connected to the external water pump through a water collecting joint 504, and water is transported to the inside of the flushing cavity 5 by the water pump; the bite plate 3 is located inside the cleaning rack, and the lower ends of the bite plate 3 are respectively provided with A sliding rod 301 is inserted into a sliding hole 302 within the cleaning rack. A U-shaped plate 303 is installed within the flushing chamber 5. The sides of the U-shaped plate 303 engage with the inner wall of the flushing chamber 5. The bottom of the bite plate 3 and the U-shaped plate 303 are connected by the sliding rod 301. A spring 306 is installed on the sliding rod 301 between the sliding hole 302 and the bite plate 3. The spring 306 on the sliding rod 301 provides a reset force for the bite plate 3 through preload. When the bite force is released, the spring 306 pushes the bite plate 3 and the U-shaped plate 303 back to their initial positions, closing the misaligned drain hole. This design achieves dynamic, cyclical regulation of the water flow's impact force: when engaged, the impact force increases to flush stubborn stains, while when released, the impact force decreases to protect the gums. The stiffness of the spring 306 can be customized according to the user's bite force range to ensure reset accuracy and response speed; the walls on both sides of the U-shaped plate 303 are respectively provided with a plurality of first drainage holes 304, and the wall surface of the flushing chamber 5 that is in contact with the U-shaped plate 303 is correspondingly provided with a plurality of second drainage holes 305, and the first drainage holes 304 and the second drainage holes 305 are arranged in an offset manner up and down. By moving the upper and lower positions of the U-shaped plate 303, the penetration area of the first drainage holes 304 and the second drainage holes 305 can be adjusted, and as the bite force increases, the penetration area of the first drainage holes 304 and the second drainage holes 305 increases, and vice versa, it decreases until it is closed; by biting the teeth on The teeth are wrapped inside the first cleaning rack 1 and the second cleaning rack 2 on the upper and lower sides, and the teeth on the upper and lower sides bite the bite plate 3. Through the linkage design of the U-shaped plate 303 and the sliding rod 301, the tooth bite force is converted into the vertical displacement of the U-shaped plate 303, and the misaligned penetration area of the first drainage hole 304 and the second drainage hole 305 is dynamically adjusted. At this time, the water in the flushing chamber 5 rushes out from the gap opened by the first drainage hole 304 and the second drainage hole 305, and flushes the side walls of the teeth, and the water flows out from both sides of the cleaning rack. When biting, the bite plate 3 drives the U-shaped plate 303 to move, and the originally misaligned drainage holes partially overlap to form a controllable water flow channel.The connection assembly maintains the relative position of the two cleaning racks through a mechanical locking structure, ensuring cavity stability during engagement. The inner walls of the first and second cleaning racks 1 and 2 are each equipped with a plurality of soft cleaning bristles 501. These bristles cooperate with the spring 306 to engage and disengage the bite plate 3. The bristles 501 are symmetrically distributed along the inner walls of the cleaning racks. During engagement, they bend and deform with the movement of the bite plate 3, exerting adaptive pressure on the tooth surface. When the upper and lower teeth engage, the bristles scrape up and down along the inner and outer walls of the teeth, combined with water flow to create a dual cleaning mode of "mechanical scraping + hydraulic flushing," which is particularly effective in physically removing plaque and food debris. Limiting bars 502 are respectively provided on the inner walls of the lower ends of the first and second cleaning racks 1 and 2. These limiting bars 502 are located above the bite plate 3 to limit the maximum rebound height of the bite plate 3 during the spring 306 repositioning process. A buffer layer is also provided on the contact surface between the limiting bars 502 and the bite plate 3 to reduce repositioning impact noise and enhance user comfort.
[0020] Specifically, the connecting assembly includes a connecting sleeve 401, a connecting rod 402 and an adjusting ring 403. The connecting sleeve 401 is symmetrically located on both sides of the bottom wall of the first cleaning rack 1, and the connecting rod 402 is symmetrically located on both sides of the bottom wall of the second cleaning rack 2. The connecting rod 402 is inserted into the connecting sleeve 401, and a raised mark 409 is provided on the outer wall of the connecting rod 402. The raised mark 409 is used to judge the telescopic length of the connecting rod 402 and the connecting sleeve 401 on both sides. The raised mark 409 is annular convex points or scale lines distributed at equal intervals. The user can intuitively judge whether the depth of the connecting rods 402 on both sides inserted into the connecting sleeve 401 is symmetrical by observing the number of exposed convex points or the position of the scale, so as to avoid tilting of the cleaning rack due to excessive adjustment on one side, which affects the occlusal alignment and cleaning effect; the adjusting ring 403 is sleeved on the The outer wall of the connecting sleeve 401 and the outer end surface of the connecting sleeve 401 are surrounded by a locking strip 404, and a cylinder 405 is provided on one side of the adjusting ring 403. By moving the adjusting ring 403, the cylinder 405 is moved to the position of the locking strip 404, and the two cooperate with each other so that the locking strip 404 tightens the connecting rod 402, thereby adjusting the distance between the first cleaning rack 1 and the second cleaning rack 2. The axial movement of the adjusting ring 403 drives the inclined surface 408 of the inner wall of the cylinder 405 to squeeze the locking strip 404. The inner wall of the cylinder 405 is provided with an inclined surface 408. The inclined surface 408 of the inner wall of the cylinder 405 is designed to convert the axial movement of the adjusting ring 403 into a radial contraction force of the locking strip 404, so that the locking strip 404 radially contracts and holds the connecting rod 402 tightly, thereby realizing stepless adjustment of the distance between the two cleaning racks. This structure has both quick locking and fine adjustment functions, can adapt to the dental arch width of different users, such as the difference between children and adults, and can be operated without the aid of external tools. The inner wall of the adjustment ring 403 is provided with a first thread structure 406, and the outer wall of the connecting sleeve 401 is correspondingly provided with a second thread structure 407. The first thread on the inner side of the adjustment ring 403 and the second thread on the outer wall of the connecting sleeve 401 form a spiral pair. By rotating the adjustment ring 403, its axial displacement can be controlled, and the degree of extrusion of the cylinder 405 on the locking strip 404 can be accurately adjusted.
[0021] During use, the rotating adjustment ring 403 drives the cylinder 405 to move axially, and the inclined surface 408 of the inner wall compresses the locking strip 404 to contract radially, clamping the connecting rod 402; observe the number of exposed raised marks 409 on the outer wall of the connecting rod 402 to ensure that the depth of the connecting rods 402 on both sides inserted into the connecting sleeve 401 is consistent, and the spacing between the two cleaning racks is adjusted to adapt to the user's dental arch width; continue to rotate the adjustment ring 403 to the predetermined position, and the locking strip 404 completely embraces the connecting rod 402, fixing the relative positions of the two cleaning racks to form a stable semi-closed cleaning cavity. The upper and lower teeth occlude the bite plate 3, pushing the sliding rod 301 downward along the sliding hole 302 of the cleaning rack, compressing the spring 306 and linking the U-shaped plate 303 to move vertically downward; the downward movement of the U-shaped plate 303 causes the originally dislocated first drainage hole 304 to partially overlap with the second drainage hole 305, and the through-hole area increases linearly with the occlusion depth, and the water in the flushing chamber 5 is accelerated to spray out through the overlapping holes; the greater the bite force, the greater the displacement of the U-shaped plate 303, the expansion of the through-hole area, and the increase of the impact force of the water flow; when the bite plate 3 moves up and down, the cleaning bristles 501 symmetrically distributed on the inner wall of the cleaning rack are squeezed and bent toward the tooth surface, applying an adaptive scraping force to the inner and outer sides of the crown. When the bite force is maintained, the U-shaped plate 303 remains in a low position, the drainage hole maintains the maximum through-area, the high-pressure water flow continuously rinses the side walls and gaps of the teeth, and the soft bristles continue to scrape the surface; after the bite is released, the spring 306 releases the preload elastic force, pushing the sliding rod 301 to rebound, driving the U-shaped plate 303 to move up and reset, the first drainage hole 304 and the second drainage hole 305 gradually dislocate and close, and the impact force of the water flow is attenuated; when the bite plate 3 approaches the initial position, its top contacts the buffer layer of the limiting strip 502, reducing the impact noise through flexible buffering and accurately limiting the reset end point of the U-shaped plate 303 to ensure that the drainage hole is completely closed. After stopping the bite, the spring 306 drives all components to reset to the initial state, the drainage hole is completely closed to block the water flow; when removing the device, reversely rotate the adjustment ring 403 to release the locking strip 404, separate the two cleaning racks and take it out.
[0022] The oral cleaning and care device drives the locking strip 404 to contract through the adjustment ring 403 of the connecting component, thereby achieving stepless adjustment of the distance between the two cleaning racks to adapt to the width of the dental arch, and ensuring symmetrical locking with the help of the raised mark 409; when the user bites up and down, the impact force of the water flow dynamically increases with the bite force, and at the same time, the symmetrical cleaning bristles 501 on the inner wall of the cleaning rack are bent and deformed due to the displacement of the bite plate 3, exerting an adaptive scraping force on the tooth surface, forming a dual cleaning mode of "high-pressure water flushing + soft-bristle mechanical scraping"; the cleaning intensity is accurately controlled through the linkage of the bite force and the mechanical structure, taking into account both efficient plaque removal and gum protection.
