DETAILED DESCRIPTION
[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0045] The embodiments of the present application will be described below with reference to the drawings. Figures 1 to 10
[0046] According to embodiments of this application, in one aspect, a nozzle 2 assembly is provided, such as... Figures 1 to 7 As shown, the device includes: a housing 1, a nozzle 2, a bracket 3, a camera 4, a supplementary light 5, and a lens 6. A water channel 17 is formed inside the housing 1, and the nozzle 2 is connected to the housing 1 and communicates with the water channel 17 inside the housing 1. Thus, after the nozzle 2 assembly is connected to the water flosser body, the water channel 17 communicates with the pump body of the water flosser body. When the pump body is working, water is drawn from the water tank and pressurized. The pressurized water flows through the water channel 17 to the nozzle 2 and is then sprayed out. The user can then rinse their teeth by aiming the nozzle 2 at their teeth.
[0047] A mounting slot 19 with an opening is provided on the outer casing 1, and the bracket 3 is connected and installed within the mounting slot 19. The camera 4 is connected to the bracket 3, and then the fill light 5 is connected to the bracket 3, so that the camera 4 and the fill light 5 are arranged side by side. The fill light 5 can be a commonly used LED bulb.
[0048] At this time, both the camera 4 and the fill light 5 are located within the mounting slot 19, with the fill light 5 positioned next to the camera 4. The lens 6 is then connected to the housing 1, sealing the opening. Since both the camera 4 and the fill light 5 are located within the mounting slot 19, the lens 6 effectively seals the camera 4 and the fill light 5 within the mounting slot 19.
[0049] With this setup, while the user rinses their teeth using the water jet from nozzle 2, camera 4 can capture images of the teeth through lens 6. Camera 4 can be connected to a display terminal such as a screen, allowing the display terminal to show the images of the teeth captured by camera 4 in real time. This enables the user to accurately rinse their teeth based on the information displayed on the display terminal. The supplementary light 5 emits light that shines through lens 6 into the oral cavity, providing supplementary lighting for camera 4 and enhancing the image capture effect, ensuring clear images are obtained.
[0050] Because the camera 4 and the fill light 5 are separate and arranged side by side, with the fill light 5 located next to the camera 4, the reflected light from the fill light 5 onto the lens 6 will not reach the camera 4, thus avoiding any impact on the camera 4 and resulting in poor image quality.
[0051] Regarding the connection between lens 6 and housing 1, such as Figure 2 , Figure 5 and Figure 6 As shown, a groove 18 is provided at the opening of the mounting groove 19. The lens 6 is placed in the groove 18, so that the groove 18 expands outward relative to the mounting groove 19, thereby forming a countersunk groove. The lens 6 is placed in the countersunk groove and bonded to the bottom of the countersunk groove, thereby connecting the lens 6 to the housing 1. At this time, the lens 6 seals the opening of the mounting groove 19.
[0052] Wherein the lens 6 can be coated with Teflon and other nano coating to prevent water accumulation, improve imaging quality and enhance user experience.
[0053] The circuit board 13 is arranged in the mounting groove 19, and the camera 4 and the fill light 5 are connected to the circuit board 13, so as to realize power supply and control of the camera 4 and the fill light 5.
[0054] As an optional embodiment, as shown in Figures 1 to 4 The support sheet 7 and the gasket 10 are arranged in the mounting groove 19. The first perforation 8 and the second perforation 9 are arranged on the support sheet 7. The support sheet 7 is placed into the mounting groove 19 from the opening until the support sheet 7 abuts against the support 3. At this time, the camera 4 extends into the first perforation 8, and the fill light 5 extends into the second perforation 9.
[0055] In this way, the support sheet 7 plays a stabilizing role on the camera 4 and the fill light 5. The shape of the first perforation 8 is consistent with the shape of the camera 4. The shape of the second perforation 9 is consistent with the shape of the fill light 5.
[0056] After the support sheet 7 is loaded, the gasket 10 is placed into the mounting groove 19 from the opening until the gasket 10 abuts against the side of the support sheet 7 away from the support 3. Then, the lens 6 is capped at the opening of the mounting groove 19, and at this time, the lens 6 abuts against the side of the gasket 10 away from the support sheet 7. In this way, the gasket 10 plays a supporting role between the lens 6 and the support 3, and increases the stability of the lens 6 and the support 3.
[0057] The first surface of the gasket 10 is bonded to the support 3, and the second surface of the gasket 10 is bonded to the support 3, further increasing the stability.
[0058] EVA glue, i.e. Ethylene Vinyl Acetate (EVA) glue or hot melt adhesive, is a high molecular compound. The main component is a copolymer of ethylene (E) and vinyl acetate (VA), and in addition, it contains plasticizer, viscosity regulator, antioxidant, filler and other components to form an adhesive with specific properties.
[0059] Moreover, the third perforation 11 and the fourth perforation 12 are arranged on the gasket 10. The camera 4 can pass through the third perforation 11 to take pictures, avoiding the gasket 10 from shielding the camera 4. The light emitted by the fill light 5 can pass through the fourth perforation 12, avoiding the gasket 10 from shielding the fill light 5.
[0060] As an optional embodiment, as shown in Figure 7As shown, the bracket 3 comprises a first bracket 31 and a second bracket 32. The first bracket 31 and the second bracket 32 are both connected to the inner wall of the mounting groove 19. The bottom of the camera 4 is connected to the first bracket 31, and the bottom of the light supplement lamp 5 is connected to the second bracket 32. Since the length of the light supplement lamp 5 is greater than the length of the camera 4. The height of the top of the second bracket 32 is set to be greater than the height of the top of the first bracket 31. In this way, after the camera 4 is connected to the first bracket 31 and the light supplement lamp 5 is connected to the second bracket 32, the side of the camera 4 away from the first bracket 31 is flush with the side of the light supplement lamp 5 away from the second bracket 32, that is, the distance from the camera 4 to the opening of the mounting groove 19 is equal to the distance from the light supplement lamp 5 to the opening of the mounting groove 19.
[0061] In this way, the shooting position of the camera 4 is flush with the light emitting position of the light supplement lamp 5, so that the light supplement lamp 5 can better realize the function of supplementing light for the camera 4 to shoot, and the imaging effect is better.
[0062] Among them, the first bracket 31 and the second bracket 32 can both be ribs connected to the inner wall of the mounting groove 19.
[0063] In an optional embodiment, as shown in Figure 3 and Figure 4 , the nozzle 2 sprays water in a first direction X, and the camera 4 shoots in a second direction Y. The water spraying direction of the nozzle 2 and the shooting direction of the camera 4 intersect at a working point. In use, the tooth is placed at the working point, and the camera 4 can shoot the tooth, and at the same time, the nozzle 2 can wash the tooth.
[0064] Among them, the included angle R between the first direction X and the second direction Y is set to be between 14 degrees and 15 degrees. In this way, it is beneficial to image acquisition and improve cleaning effect.
[0065] Especially, the included angle R between the first direction X and the second direction Y is set to 14.5 degrees, the image acquisition is clearer, and the cleaning effect is better.
[0066] In a further embodiment, the distance L between the working point and the nozzle 2 is 17-19 mm. In this way, it is beneficial to image acquisition and improve cleaning effect.
[0067] Especially, the distance L between the working point and the nozzle 2 is set to 18 mm, the image acquisition is clearer, and the cleaning effect is better.
[0068] As an optional embodiment, as shown in Figure 1 , Figure 2 and Figure 8As shown, the spray head 2 comprises a connector 21 and a nozzle 22. The connector 21 is tubular and connected to the housing 1, and the connector 21 is in communication with the water channel 17. The nozzle 22 is detachably connected to the end of the connector 21 away from the housing 1, so that the nozzle 22 is in communication with the water channel 17 through the connector 21. When the pump body is working, water is pumped out of the water tank and pressurized, and the pressurized water flows to the nozzle 22 through the water channel 17 and the connector 21.
[0069] Since the nozzle 22 is detachably connected to the connector 21, a plurality of different nozzles 22 can be provided, such as soft rubber nozzles 22, hard rubber nozzles 22, or ordinary nozzles 22. The appropriate nozzle 22 is selected and connected to the connector 21 for use. When another nozzle 22 is needed, the nozzle 22 currently connected to the connector 21 is detached, and the desired nozzle 22 is connected to the connector 21. This can meet the quick switching of different use requirements of the user, and there is no need to have multiple spray head 2 assemblies or oral irrigators.
[0070] Specifically, as shown in Figure 1 , Figure 2 and Figure 8 , an external thread is provided on the outer wall of the end of the connector 21 away from the housing 1, and an internal thread is provided on each nozzle 22. Since the external thread on the connector 21 cooperates with the internal thread on the nozzle 22, each nozzle 22 can be screwed onto the connector 21 to complete the connection, and the disassembly and assembly are more convenient.
[0071] For the soft rubber nozzle 22, in an alternative embodiment, as shown in Figure 9 , the spray head 2 further comprises an extension nozzle 23, and the extension nozzle 23 is made of soft rubber material. An installation hole 14 is formed at the end of the nozzle 22 away from the housing 1. After the extension nozzle 23 is installed in the installation hole 14, the extension nozzle 23 is combined with the nozzle 22. The outer diameter of the extension nozzle 23 is greater than the hole diameter of the installation hole 14, and since the extension nozzle 23 is made of soft rubber material, the extension nozzle 23 can be squeezed and passed through the installation hole 14, so that the outer wall of the extension nozzle 23 abuts against the hole wall of the installation hole 14, completing the combination and fixation of the extension nozzle 23 and the nozzle 22. When the pump body is working, water is pumped out of the water tank and pressurized, and the pressurized water flows to the extension nozzle 23 through the water channel 17, the connector 21, and the nozzle 22.
[0072] For the hard rubber nozzle 22, in a further embodiment, as shown in Figure 10A first stop ring 15 is arranged on the outer wall of one end of the extension nozzle 23. A second stop ring 16 is arranged on the inner wall of the mounting hole 14. The extension nozzle 23 is inserted from the first end of the nozzle 22 until the extension nozzle 23 extends out of the second end of the nozzle 22, and the side of the first stop ring 15 of the extension nozzle 23 facing away from the first end of the nozzle 22 abuts against the side of the second stop ring 16 of the mounting hole 14 facing toward the first end of the nozzle 22, completing the combination of the extension nozzle 23 and the nozzle 22, and then the nozzle 22 is connected to the connector 21. During the operation of the pump body, water is pumped from the water tank and pressurized, and then flows to the connector 21 and the nozzle 22 in sequence through the water channel 17, and then flows to the extension nozzle 23 and is sprayed out.
[0073] According to an embodiment of the present application, in another aspect, a water pick is also provided, which comprises any of the above-mentioned nozzle 2 assemblies. The water pick further comprises a water pick body, which comprises a base shell, a pump body, a water tank, and the like. The pump body and the water tank are arranged in the base shell. The nozzle 2 assembly comprises a shell 1 and a nozzle 2 arranged on the shell 1. The shell 1 is provided with a water channel 17 communicating with the nozzle 2. The water channel 17 communicates with the water tank through the pump body.
[0074] After the nozzle 2 is aligned with the teeth, water is pumped from the water tank by the pump body and pressurized, and the generated high-speed or pulsed water flow is sprayed out of the nozzle 2 to clean and rinse the areas that are difficult to reach, such as the tooth gaps and gum grooves. The impact force of the water flow is used to flush away the dental plaque and food residues attached to the surface of the teeth.
[0075] Although the embodiments of the present application are described in conjunction with the accompanying drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the present application.
