[0022] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0023] refer to Figure 1 and Figure 2 The present invention discloses a cleaning mechanism 10, which can be applied to oral cleaning equipment 20 to improve the user experience.

[0024] refer to Figure 1 , Figure 2 and Figure 3The oral hygiene device 20 may include a housing 21, a pumping mechanism 22, an auxiliary pump 23, a suction tube 24, and a cleaning mechanism 10. The pumping mechanism 22 and the auxiliary pump 23 are disposed within the housing 21. Specifically, the housing 21 includes a base 211, a first liquid reservoir 212, and a second liquid reservoir 213. The base 211 has a first receiving groove 211a and a second receiving groove 211b. The first liquid reservoir 212 is accommodated and confined within the first receiving groove 211a, and the second liquid reservoir 213 is accommodated and confined within the second receiving groove 211b. The first liquid reservoir 212 can be used to store cleaning water, and the second liquid reservoir 213 can be used to store dental cleaning materials, such as toothpaste. The pump mechanism 22 may include a first branch pipe 221, a second branch pipe 222, a manifold 223, and a pump 224. The two ends of the first branch pipe 221 are connected to the inlet of the pump 224 and the first reservoir 212, respectively. The two ends of the second branch pipe 222 are connected to the inlet of the pump 224 and the second reservoir 213, respectively. One end of the manifold 223 is connected to the outlet of the pump 224, and the other end extends from inside the housing 21 to the outside and communicates with the cleaning mechanism 10. The pump 224 may have one inlet, two independent inlets, or a single main inlet split into two. The pump 224 draws cleaning water stored in the first reservoir 212 and dental cleaning material stored in the second reservoir 213 into the pump 224, mixes them to form a cleaning fluid, and finally enters the user's oral cavity through the manifold 223 and the cleaning mechanism 10, thereby improving the ease of use of the oral cleaning device 20. The liquid pump 224 can be a gear pump or other type of pump, which can draw fluid from the first liquid storage box 212 and the second liquid storage box 213 and output it to the cleaning mechanism 10 after mixing.

[0025] The first reservoir 212 can be rectangular and detachably connected to the housing 211 by means of snap-fit ​​or magnetic attraction. The wall of the first receiving groove 211a of the housing 211 can have a notch 211a1, which can be used to accommodate the user's finger, so that the user can remove the first reservoir 212 from the first receiving groove 211a to replenish the cleaning water. The second reservoir 213 can be cylindrical and detachably connected to the first branch tube 221, for example by threaded connection or snap-fit, so that the user can easily replace the second reservoir 213 after using the cleaning material, or inject cleaning material into the second reservoir 213.

[0026] refer to Figure 1 , Figure 3 , Figure 4 and Figure 5In some embodiments, the housing 211 of the housing 21 may be provided with a storage groove 211c for storing the cleaning mechanism 10. Specifically, the bottom of the storage groove 211c may have an overlapping boss 211c1 that matches the shape of the cleaning mechanism 10, for example, the outer contour of the cross-section of the overlapping boss 211c1 is approximately triangular. The overlapping boss 211c1 and the groove wall of the storage groove 211c form a recessed groove 211c2. When not in use or after use, the cleaning mechanism 10 can be placed in the storage groove 211c and abut against the overlapping boss 211c1, improving the convenience of storage.

[0027] Furthermore, such as Figure 4 As shown, the housing 21's base 211 may have a waste liquid chamber 211d and a liquid outlet 211e communicating with the waste liquid chamber 211d. The liquid outlet 211e is located at the bottom of the waste liquid chamber 211d, and the waste liquid chamber 211d communicates with the receiving groove 211c. The base 211 may have an opening 211f, which communicates with the waste liquid chamber 211d and with the recessed groove 211c2 of the receiving groove 211c. The opening 211f may be circular, and the bottom cross-section of the recessed groove 211c2 may be arc-shaped. The bottom edge of the opening 211f may connect with the arc-shaped bottom of the groove, so that the two are smoothly connected and the bottom of the entire recessed groove 211c2 may be inclined towards the opening 211f. When the cleaning mechanism 10 is stored in the storage tank 211c, residual liquid on the cleaning mechanism 10 located in the recessed groove 211c2 can be guided through the bottom of the recessed groove 211c2 to the opening 211f, and then flow into the waste liquid chamber 211d through the opening 211f, thus preventing water accumulation inside the storage tank 211c from causing bacterial growth, component corrosion, and other problems. Waste liquid in the waste liquid chamber 211d can be connected to an external pipe through the outlet 211e and discharged into the water tank to prevent soiling the support platform of the oral cleaning device 20.

[0028] refer to Figure 1 , Figure 3 and Figure 4In some embodiments, the housing 211 may include a housing 2111, a first cover 2112 and a second cover 2113 connected to the housing 2111. The second cover 2113 may be fitted onto the inlet 23a of the auxiliary pump 23 to facilitate the assembly of the auxiliary pump 23 and the housing 2111. The housing 2111 may have a first receiving groove 211a, a second receiving groove 211b, a notch 211a1, and a storage groove 211c. In some embodiments, the oral cleaning device 20 may include a battery assembly (not shown) and a circuit board 25. The battery assembly is electrically connected to the circuit board 25, and other electrical components may be electrically connected to the circuit board 25 to be powered by the battery assembly. The battery assembly may be a lithium battery capable of repeated charging and discharging. In some embodiments, the battery assembly may be disposed inside the housing 2111 or disposed outside the housing 2111 and detachably connected to the housing 2111. The circuit board 25 can be fixedly connected to the side of the first cover 2112 facing the base 2111 and can integrate electronic components such as a display screen and buttons. These electronic components can cooperate with corresponding openings on the first cover 2112 to realize corresponding functions such as displaying battery level, controlling start / stop, and gear position. In some embodiments, the second cover 2113 can have a first through hole 21131 and a second through hole 21132. The manifold 223 can extend from the inside of the base 2111 to the outside through the first through hole 21131, and the inlet 23a of the auxiliary pump 23 is exposed through the second through hole 21132 for connection with the suction tube 24. When assembling the oral cleaning device 20, the pump mechanism 22, the first branch pipe 221, the second branch pipe 222, the manifold 223, and the auxiliary pump 23 can be installed on the housing 21 first, and then the first cover 2112 and the second cover 2113 can be connected to the base 211 to reduce the assembly difficulty of the oral cleaning device 20.

[0029] refer to Figure 1 , Figure 3 and Figure 5 In some embodiments, the auxiliary pump 23 is housed within the housing 21. One end of the suction tube 24 is connected to the inlet 23a of the auxiliary pump 23, and the other end is connected to the cleaning mechanism 10. The outlet 23b of the auxiliary pump 23 is connected to the waste liquid chamber 211d to guide waste liquid from the user's mouth to the waste liquid chamber 211d. During oral cleaning, this arrangement prevents the unidirectional delivery of liquid by the pump mechanism 22 from causing the cleaning fluid to accumulate in the mouth, thus avoiding the need for the user to frequently remove the cleaning mechanism 10 and spit out the waste liquid. In other words, the user only needs to insert the cleaning mechanism 10 into their mouth once, and the entire oral cleaning process can be completed after a predetermined cleaning time, improving ease of use. The predetermined cleaning time can be achieved using a control circuit, which will not be elaborated here. The specific structures of the auxiliary pump 23 and the liquid pump 224 can adopt mature fluid pump solutions, which will not be described in detail here.

[0030] refer to Figure 1 , Figure 6 and Figure 7 In some embodiments, the cleaning mechanism 10 may include a handle 11, a drive assembly 12, and a cleaning assembly 13. The handle 11 includes a handle housing 111 and a flexible mouthpiece 112 connected to the handle housing 111. The drive assembly 12 is disposed on the handle housing 111. The cleaning assembly 13 is linked to the output end of the drive assembly 12 and extends from one side of the flexible mouthpiece 112. The cleaning assembly 13 is used to enter the user's mouth. The drive assembly 12 can drive the cleaning assembly 13 to reciprocate within the user's mouth to clean the user's mouth. The flexible mouthpiece 112 is used to abut against and cover the user's lips. By providing a flexible mouthpiece 112 on the side of the handle 11 near the cleaning assembly 13 to abut against and cover the user's lips, the cleaning mechanism 10 prevents liquid in the user's mouth from splashing outwards with the movement of the cleaning assembly 13 or the impact of water flow when the user uses the cleaning mechanism 10 to clean their mouth, thereby improving the user experience.

[0031] refer to Figure 6 , Figure 7 and Figure 8 In some embodiments, the flexible mouthpiece 112 has a hollow channel 112a and includes a first end 112b and a second end 112c. The first end 112b is fitted onto the handle shell 111, and the second end 112c has a recessed area 112d for conforming to the lips. The cleaning component 13 protrudes from the recessed area 112d, and the hollow channel 112a extends from the recessed area 112d to the first end 112b. Specifically, as... Figure 7 As shown, the flexible mouthpiece 112 may include an integrally formed connecting portion 1121, a blocking portion 1122, and a telescopic portion 1123 located between the connecting portion 1121 and the blocking portion 1122. The connecting portion 1121 has a first end 112b, the blocking portion 1122 has a second end 112c and a recessed area 112d, and a hollow channel 112a extends from the blocking portion 1122 through the telescopic portion 1123 to the connecting portion 1121. During the process of the recessed area 112d pressing against the user's lips, the telescopic portion 1123 can undergo telescopic deformation to change the distance between the first end 112b and the second end 112c, thereby improving the fit between the flexible mouthpiece 112 and the user's lips. In some embodiments, the flexible mouthpiece 112 may be made entirely of an elastic and flexible material such as silicone, giving it good telescopic deformation capability and a soft texture to improve user comfort.

[0032] Continue to refer to Figure 6 , Figure 7 and Figure 8In some embodiments, the handle housing 111 has a suction channel 111a communicating with the hollow channel 112a. The cleaning mechanism 10 includes a suction member 14 that passes through the flexible nozzle 112 and is connected to the handle housing 111. The suction member 14 is hollow and communicates with the suction channel 111a, and the suction member 14 protrudes from the recessed area 112d. Specifically, as Figure 8 As shown, the handle shell 111 includes an integrally formed handle portion 1111 and a protrusion portion 1112. The protrusion portion 1112 protrudes from the handle portion 1111. The connecting portion 1121 of the flexible nozzle 112 is sleeved on the end of the protrusion portion 1112 near the cleaning component 13. The suction channel 111a may include a first channel 111a1 and a second channel 111a2 that are connected. The handle portion 1111 has the first channel 111a1, and the protrusion portion 1112 has the second channel 111a2. The suction member 14 may include a hollow handle 141 that is pluggably disposed in the handle shell 111, and a deformable portion 142 connected to the end of the hollow handle 141 away from the handle shell 111. The hollow handle 141 portion of the suction member 14 can pass through the second channel 111a2 of the protrusion portion 1112 and can be connected to the handle shell 111 by means of snap-fit ​​or other methods. The deformable portion 142 may have multiple drainage grooves 1421 communicating with the hollow handle 141. The hollow handle 141 is connected to the auxiliary pump 23 of the oral cleaning device 20 through the suction channel 111a, so as to extract waste liquid during the oral cleaning process by the auxiliary pump 23, preventing the cleaning fluid from accumulating in the oral cavity due to the one-way liquid delivery of the pump mechanism 22. The deformable portion 142 protrudes from the recessed area 112d and extends into the cleaning component 13 to better absorb waste liquid in the oral cavity.

[0033] refer to Figure 6 , Figure 7 , Figure 8 and Figure 9 In some embodiments, the drive assembly 12 may include a driver 121 connected to the handle housing 111, and a first rod 122 and a second rod 123 disposed on radially opposite sides of the output end of the driver 121 and arranged in parallel with and linked to the output end of the driver 121. A cleaning assembly 13 is connected to the same end of the first rod 122 and the second rod 123. The ends of the first rod 122 and the second rod 123 opposite to the cleaning assembly 13 are retractably disposed on the protrusion 1112 of the handle 11. Figure 6As shown, the actuator 121 is exposed outside the handle 11 and confined within the handle 11. In other embodiments, the actuator 121 may be hidden inside the handle 11 to make the appearance of the cleaning mechanism 10 more concise. In some embodiments, the first rod 122 and the second rod 123 are mirror-symmetrically arranged on both sides of the output end of the actuator 121 and linked thereto, and the first rod 122 and the second rod 123 extend and retract relative to the handle 11 in a first direction. In some embodiments, the actuator 121 may be a servo motor to improve the motion control accuracy of the cleaning component 13 and obtain the advantages of long life and low noise. For example, during the reciprocating motion of the cleaning component 13 along the gum curve, the speed and acceleration of the cleaning component 13 can be realized by controlling the rotational speed of the actuator 121. When the cleaning component 13 abuts against the inner wall of the user's mouth in one direction, the load on the actuator 121 will change significantly. Therefore, the motion of the cleaning component 13 can be more precisely controlled by combining the load feedback of the actuator 121 to improve the comfort of cleaning. In some implementations, a gear reduction structure may be configured inside the driver 121 to ensure the output torque of the driver 121.

[0034] Specifically, the protrusion 1112 of the handle housing 111 has two spaced-apart through holes 11121. The first rod 122 and the second rod 123 are correspondingly inserted and slidably fitted into the two through holes 11121. One end of the handle 1111 may have a connecting platform 11112. The connecting platform 11112 is used to fix the driver 121 to the handle housing 111, and the circumferential contour of the connecting platform 11112 can match the circumferential contour of the driver 121. The driver 121 abuts against the connecting platform 11112 and can be fixedly connected to the connecting part 1121 by means of threads or snap-fit, so that the overall appearance of the assembled cleaning mechanism 10 is more complete.

[0035] Furthermore, the drive assembly 12 may include a drive gear 124 fixedly connected to the output end of the driver 121. The first lever 122 and the second lever 123 each have a rack portion 12a, and the rack portions 12a of the first lever 122 and the second lever 123 mesh one-to-one with opposite radial sides of the drive gear 124. Specifically, as... Figure 9As shown, the handle 1111 has a pivot hole 11111 at one end near the driver 121. Two through holes 11121 are arranged opposite each other on both sides of the pivot hole 11111 and communicate with the pivot hole 11111. When the first rod 122 and the second rod 123 are correspondingly inserted into the two through holes 11121, the rack portion 12a of the first rod 122 and the rack portion 12a of the second rod 123 at least partially protrude from the hole wall of the pivot hole 11111 for meshing with the drive gear 124. During the operation of the cleaning mechanism 10, when the driver 121 drives the first rod 122 to move in the forward direction of the first direction, the second rod 123 moves in the reverse direction of the first direction, so that the cleaning assembly 13 can reciprocate along the curve of the gums on both sides of the oral cavity to clean the teeth.

[0036] Furthermore, the first rod 122, used to connect one end of the cleaning component 13, and the second rod 123, used to connect one end of the cleaning component 13, are inserted into the flexible mouthpiece 112 to prevent liquid in the oral cavity from splashing due to the reciprocating motion of the first rod 122 and the second rod 123. In some embodiments, the suction member 14 may be disposed between the first rod 122 and the second rod 123 and spaced apart from the first rod 122 and the second rod 123 to prevent the suction member 14 from interfering with the movement of the first rod 122 and the second rod 123.

[0037] In some embodiments, a battery, such as a rechargeable lithium battery, may be housed within the handle housing 111 to power the driver 121. In other embodiments, the handle housing 111 may be connected to an external power source, for example, the driver 121 may be powered by a battery within the housing 21. Of course, in some embodiments, the housing 21 may be connected to an external power source, such as a household power source, to power electronic components such as the pumping mechanism 22, the auxiliary pump 23, and the driver 121.

[0038] refer to Figure 6 , Figure 8 and Figure 10 In some embodiments, the cleaning component 13 includes a connector 131, a flexible dental sleeve 132, and flexible brush bodies 133. Two connectors 131 are provided, detachably connected one-to-one to a first rod 122 and a second rod 123. The flexible dental sleeve 132 has a groove 132a for accommodating the user's teeth, covering both the inner and outer sides of the teeth. A plurality of spaced-apart flexible brush bodies 133 protrude from the groove wall of the groove 132a. In some embodiments, a suction member 14 is disposed between the two connectors 131 and spaced apart from the connectors 131 and the flexible dental sleeve 132 to prevent obstruction of the movement of the cleaning component 13. Specifically, as... Figure 10As shown, each connector 131 may include a first connecting end 1311 and a second connecting end 1312. The first connecting end 1311 is used to connect with the first rod 122 or the second rod 123. The second connecting end 1312 may be provided with a protrusion 13121. The flexible dental brace 132 is provided with a connecting hole 132b that matches the protrusion 13121. The connector 131 is fixedly connected by matching the protrusion 13121 with the connecting hole 132b and can be fixedly connected by means of snap-fit, adhesive bonding, heat fusion, etc. to prevent the connector 131 from easily separating from the flexible dental brace 132.

[0039] Continue to refer to Figure 6 , Figure 8 and Figure 10 In some embodiments, the first rod 122, the second rod 123, and the connector 131 are hollow, and the first rod 122 and the second rod 123 are respectively connected to the corresponding connector 131. Two flexible dental sleeves 132 are provided, one flexible dental sleeve 132 is located on the same side of the two connectors 131, and the other flexible dental sleeve 132 is located on the opposite side of the two connectors 131. Each flexible dental sleeve 132 has multiple drainage holes 132c communicating with the groove 132a and the interior of the connector 131. Specifically, the structure of the two flexible dental sleeves 132 and the connector 131 is such that the groove 132a of one flexible dental sleeve 132 faces the upper jaw of the oral cavity, and its structure is adapted to the curvature of the upper jaw; the groove 132a of the other flexible dental sleeve 132 faces the lower jaw of the oral cavity, and its structure is adapted to the curvature of the lower jaw. During the operation of the cleaning component 13, any connector 131 drives the two flexible dental sleeves 132 connected to it to move synchronously. With the above structure, when the user places the cleaning component 13 into the mouth, the upper flexible dental sleeve 132 covers the inner and outer sides of the upper gum, and the lower flexible dental sleeve 132 covers the inner and outer sides of the lower gum. Combined with the reciprocating motion of the flexible dental sleeves 132 and the flexible brush body 133 along the gums, the upper and lower teeth and the gaps between the teeth and the gums are thoroughly cleaned. There is no need to adjust the posture of the hand holding the handle 11 or the direction of force, simplifying the oral cleaning process and improving the efficiency of oral cleaning.

[0040] refer to Figure 8 and Figure 10In some embodiments, the flexible dental brace 132 includes an integrally formed inner wall 1321, an outer wall 1322, and a bottom wall 1323 connected to the same end of the inner wall 1321 and the outer wall 1322. The bottom wall 1323 may have a connecting hole 132b, and the outer wall 1322 may have a liquid outlet hole 132c. The inner wall 1321, the outer wall 1322, and the bottom wall 1323 enclose a groove 132a that matches the shape of the jawbone. The inner wall 1321 and the outer wall 1322 each include a plurality of integrally formed mounting portions 132d. A deformation groove 132e is formed between adjacent mounting portions 132d to more easily deform and adapt to the user's jawbone curve when the flexible dental brace 132 moves along the user's jawbone curve, thereby improving the comfort of use. The flexible brush body 133 is connected to the mounting portion 132d and protrudes into the groove 132a. Specifically, the mounting part 132d has a fixing groove 132f on the side opposite to the groove 132a. The fixing groove 132f communicates with the groove 132a. The flexible brush body 133 may include bristles 1331 and a fixing part 1332. The bristles 1331 pass through the fixing groove 132f and protrude from the groove 132a to contact the tooth surface and the upper and lower gums, thereby achieving the brushing cleaning operation. The fixing part 1332 can be fixed to the fixing groove 132f of the flexible dental sleeve 132 by means of heat fusion or other methods to ensure the reliability of the connection between the flexible brush body 133 and the flexible dental sleeve 132.

[0041] In some embodiments, the connector 131 may be made of a hard plastic material, such as polypropylene, that is non-irritating to the oral cavity, impact-resistant, easy to clean, and compatible with soft plastic components, to serve as the support structure for the flexible brace 132. The flexible brace 132 may be made of a wear-resistant, aging-resistant, and easy-to-clean soft plastic material, such as food-grade silicone, to improve user comfort.

[0042] refer to Figure 6 and Figure 7 In some embodiments, the cleaning mechanism 10 may include quick-connect fittings 15. The ends of the first rod 122 and the second rod 123 furthest from the cleaning component 13 are respectively sealed with quick-connect fittings 15. One end of the quick-connect fitting 15 can be threaded for convenient and quick connection to the first rod 122 and the second rod 123. The other end of the quick-connect fitting 15 can be reliably fitted onto the manifold 223 through deformation, thereby achieving convenient connection between the manifold 223 and the first rod 122 and the second rod 123. After the first rod 122 and the second rod 123 are connected to the pumping mechanism 22 of the oral cleaning device 20 via corresponding quick-connect fittings 15 and manifolds 223, leakage at the connection between the first rod 122, the second rod 123 and the manifold 223 of the pumping mechanism 22 can be prevented.

[0043] In some embodiments, the other ends of the first rod 122 and the second rod 123 are pluggably connected to and sealed with the connector 131. Specifically, taking the first rod 122 and the connector 131 as an example, the cleaning mechanism 10 may include a snap-fit ​​member 16 disposed between the first rod 122 and the connector 131. One end of the snap-fit ​​member 16 may be fixedly connected to the first rod 122 by means of threads, etc., and the other end may pass through the connector 131 and cooperate with snap-fit, etc., to achieve a detachable connection between the snap-fit ​​member 16 and the connector 131. For example, a deformable connector 131 may be fitted onto the snap-fit ​​member 16. The connection method between the second rod 123 and the connector 131 may refer to the connection method between the first rod 122 and the connector 131 to achieve detachable replacement of the cleaning component 13 and the handle 11, avoiding the growth of bacteria and mold due to long-term use of the cleaning component 13, and ensuring the hygiene of the cleaning mechanism 10.
