Detailed Implementation

[0037] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0038] Example:

[0039] See Figures 1 to 9 This utility model discloses an oral care device capable of spraying oral care liquid, comprising a bite block 100, a suction structure 200, a control structure 300, and a cleaning structure 400. The bite block 100 has bite grooves 110 at its top and bottom, and a first through hole 120 and a second through hole 130. The suction structure 200 is installed at the first through hole 120 for suctioning wastewater from the oral cavity. The cleaning structure 400 is installed at the second through hole 130 for spraying oral care liquid. The control structure 300 includes a squeezing block 330, a pushing block 320, and a control rod 310. The control rod 310 is rotatably engaged with the bite block 100 in a direction parallel to the axial direction of the first through hole 120. The pushing block 320 is slidably connected to the bite block 100, and the pushing block 320 is threadedly connected to the control rod 310. The extrusion block 330 is slidably connected to the bite block 100 along the radial direction of the first through hole 120. The extrusion block 330 and the control rod 310 are engaged by an inclined surface so that when the control rod 310 rotates in the first direction, the extrusion block 330 can be pushed into the first through hole 120 by the push block 320.

[0040] The oral care device with sprayable oral care solution disclosed in this embodiment effectively suctions out dirty water in the oral cavity and sprays oral care solution, improving oral cleaning effect. The suction action of the suction structure 200 can be controlled by rotating the control lever 310, which is simple, reliable, and highly precise, meeting the needs of different patients. By setting up a cleaning structure 400 and installing this structure at the second through hole 130, the device can spray oral care solution during oral care, which helps to clean dirt and bacteria in the oral cavity and improve the overall cleanliness of the oral cavity. The suction structure 200 is installed at the first through hole 120, which can effectively suction out dirty water generated in the oral cavity, preventing patients from discomfort or infection caused by accidental aspiration of dirty water, and also helps to keep the oral cavity clean and dry. The bite block 100 is provided with a bite groove 110 to facilitate patient biting. At the same time, the bite block 100 integrates the first through hole 120 and the second through hole 130, which are used to install the suction structure 200 and the cleaning structure 400 respectively, making the entire device compact, highly integrated, easy to carry and use.

[0041] See Figure 1 In this embodiment, the clockwise direction around the first through hole 120 in the figure is taken as the first direction, and the counterclockwise direction around the first through hole 120 in the figure is taken as the second direction.

[0042] In one embodiment, the control structure 300 further includes an elastic element 340. The two ends of the elastic element 340 act on the pressing block 330 and the biting block 100, respectively, and the elastic element 340 is used to drive the pressing block 330 to move outward toward the first through hole 120.

[0043] When the control lever 310 rotates, causing the pressing block 330 to enter the first through hole 120, the elastic element 340 is compressed. When the control lever 310 rotates in the opposite direction or is released, the elastic element 340 can drive the pressing block 330 to move outward toward the first through hole 120, thereby achieving automatic reset.

[0044] The presence of the elastic element 340 ensures that the control structure 300 remains stable when not subjected to external forces, preventing the squeezing block 330 from accidentally entering or leaving the first through hole 120 due to misoperation or external interference. This improves the reliability and stability of the device and ensures safety during oral care.

[0045] In one embodiment, the interface of the extrusion block 330 in the axial direction of the first through hole 120 is U-shaped, the push block 320 is engaged in the extrusion block 330, and elastic members 340 are respectively provided on both sides of the extrusion block 330.

[0046] The concave interface design of the squeezing block 330 along its axial direction provides a stable locking space for the push block 320. This ensures that the push block 320 is firmly fixed within the squeezing block 330, preventing it from falling off or loosening due to vibration or misoperation during oral care, thus guaranteeing the stability and reliability of the device. Elastic elements 340 are provided on both sides of the squeezing block 330 to ensure that the thrust on the squeezing block 330 is evenly distributed to both sides when the control lever 310 rotates, preventing skewing or jamming caused by uneven force distribution.

[0047] In one embodiment, the bite block 100 is provided with a control hole 140, a first sliding groove 170, and a second sliding groove 180. The axis of the control hole 140 is parallel to the axis of the first through hole 120. The first sliding groove 170 extends along the axis of the control hole 140 and is larger than the control hole 140. The two ends of the second sliding groove 180 communicate with the first sliding groove 170 and the first through hole 120, respectively, and the second sliding groove 180 is perpendicular to both the first through hole 120 and the control hole 140.

[0048] The control rod 310 is rotatably engaged with the control hole 140. This rotatable engagement allows the control rod 310 to rotate along a fixed axial direction, thereby precisely controlling the movement of the extrusion block 330.

[0049] The push block 320 is slidably engaged with the first slide groove 170, and the pressing block 330 is slidably engaged with the second slide groove 180. This ensures that the push block 320 and the pressing block 330 do not deviate from the predetermined trajectory during movement, thereby improving the stability and durability of the device.

[0050] By providing control holes 140, a first sliding groove 170, and a second sliding groove 180 on the bite block 100, and by making these structures interconnected and vertically arranged, the internal space of the device is effectively utilized. This design makes the entire device structure more compact, easier to carry and use, and also improves the aesthetics of the device.

[0051] In one embodiment, the bite block 100 is provided with a first protrusion 150. The first protrusion 150 extends radially along the control hole 140, and the cross-section of the first protrusion 150 is set as semi-circular.

[0052] The control lever 310 includes a first lever 311 and a second lever 312 coaxially arranged, with the diameter of the first lever 311 being larger than the diameter of the second lever 312. The second lever 312 is threaded, and the first lever 311 has a second protrusion 314 on the side facing the biting block 100 for engaging with the first protrusion 150. The cross-section of the second protrusion 314 is semi-circular.

[0053] The first protrusion 150 extends radially along the control hole 140, and its cross-section is semi-circular. It cooperates with the second protrusion 314 (also with a semi-circular cross-section) on the control rod 310 to form an effective limiting and positioning mechanism. This ensures that the control rod 310 will not move axially or disengage from the control hole 140 during rotation, thereby maintaining the stability and reliability of the device.

[0054] In one embodiment, at least one of the first protrusion 150 and the second protrusion 314 is provided in multiples. Each first protrusion 150 is provided at circumferential intervals along the control hole 140; or each second protrusion 314 is provided at circumferential intervals along the first rod 311.

[0055] The arrangement of multiple first protrusions 150 or second protrusions 314 increases the contact points between the biting block 100 and the control rod 310, thereby enhancing the limiting effect and allowing the control rod 310 to stay in more positions to control the squeezing force of the squeezing block 330 on the suction structure 200.

[0056] Alternatively, only one first protrusion 150 can be set, and multiple second protrusions 314 can be set; or only one second protrusion 314 can be set, and multiple first protrusions 150 can be set; or multiple first protrusions 150 and multiple second protrusions 314 can be set at the same time, with the positions of multiple first protrusions 150 and multiple second protrusions 314 corresponding one-to-one. This can reduce the squeezing force borne by a single first protrusion 150 and a single second protrusion 314 when the control lever 310 is stopped, thereby extending the service life of the device.

[0057] In one embodiment, the second protrusion 314 is semi-cylindrical or hemispherical. The semi-cylindrical or hemispherical second protrusion 314 can form a good fit with the first protrusion 150 on the bite block 100, and the semi-cylindrical or hemispherical second protrusion 314 can form a good fit with the first protrusion 150 on the bite block 100.

[0058] In one embodiment, the bite block 100 is provided with a plurality of positioning holes 160. The plurality of positioning holes 160 are arranged circumferentially along the control hole 140 and are spaced apart from the first protrusion 150, providing additional fixing points for the control rod 310.

[0059] A positioning rod 313 is provided on the first rod 311. The positioning rod 313 is slidably connected to the first rod 311 in a direction parallel to the axis of the control hole 140. The position of the positioning rod 313 corresponds to the position of the positioning hole 160. The positioning rod 313 can be slid to enter or leave the positioning hole 160.

[0060] When the positioning rod 313 slides into the positioning hole 160, it effectively locks the position of the control rod 310, preventing accidental rotation or movement when no external force is applied, thereby enhancing the stability and fixation of the device. The design of the positioning rod 313 allows the operator to easily lock or unlock the position of the control rod 310 by sliding it. This intuitive and simple operation improves ease of use, enabling users to adjust and control the state of the device more quickly.

[0061] The multiple positioning holes 160 provide multiple positioning options, allowing the control rod 310 to be fixed in different positions, thereby facilitating the control of the squeezing force of the squeezing block 330 on the suction structure 200.

[0062] In one embodiment, the end of the extrusion block 330 facing the control hole 140 is set as an arc surface, and the diameter of the arc surface of the end of the extrusion block 330 facing the control hole 140 is equal to the diameter of the control hole 140.

[0063] The curved design of the extrusion block 330 matches the shape of the control hole 140. When the extrusion block 330 moves to the vicinity of the control hole 140, it can fit tightly against the edge of the control hole 140, forming a good seal. This design helps prevent liquids or food residues during oral care from entering the interior of the control hole 140, keeping the device clean and hygienic.

[0064] In addition, the curved surface design increases the friction between the extrusion block 330 and the suction structure 200, thereby making the suction structure 200 more stable and secure.

[0065] In one embodiment, the bite block 100 is provided with a control structure 300 at both the first through hole 120 and the second through hole 130.

[0066] The dual control structure 300 allows users to operate two functions simultaneously, thereby improving operational efficiency. For example, while cleaning teeth, another function, such as the flow of mouthwash, can be controlled independently, making the entire oral care process smoother and more efficient.

[0067] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
