[0001] The utility model relates to the technical field of tooth washer, in particular to a tooth washer with a large gear having an oil storage tank structure. Background Art

[0002] A water flosser generally refers to a water flosser. A water flosser is an auxiliary tool for cleaning the oral cavity. It uses pulsed water flow to clean teeth and interdental spaces. It is mainly portable and desktop. The general flushing pressure is 0 to 90 psi.

[0003] Most of the existing water flossers use a motor to drive the small gear and the large gear to mesh to transmit the piston, so as to achieve the purpose of spraying liquid for cleaning teeth, and lubricating liquid is applied to the large gear to lubricate it, so as to increase the service life of the small gear and the large gear, while ensuring the transmission effect.

[0004] However, this method has certain defects. During the use of the toothbrush, the large gear will rotate rapidly, so the applied lubricant will be thrown out by the rotating large gear, which accelerates the loss of the lubricant. In addition, the lack of lubricant will increase the friction when the large gear and the small gear are meshed, which will generate noise and reduce the service life. Therefore, the present application provides a toothbrush with an oil storage tank structure on the large gear to meet the needs. Utility Model Content

[0037] Example: Reference Figure 1-4The tooth washer with a large gear having an oil storage tank structure shown in the figure comprises a housing 1 and a nozzle for flushing teeth. This is the prior art and will not be described in detail. A large gear 4 is rotatably connected inside the housing 1, and an oil storage structure is provided on the large gear 4. A driving structure for driving the large gear 4 is also provided in the housing 1.

[0038] The oil storage structure provides storage space for the lubricating oil on the large gear 4;

[0039] A transmission structure is provided on the large gear 4, a pump body 11 is also provided in the housing 1, and a connecting pipe 16 for conveying liquid is also provided in the housing 1, the connecting pipe 16 is connected to the pump body 11, and the transmission structure cooperates with the pump body 11, and a water outlet connector 13 is also plugged into one end of the pump body 11;

[0040] The transmission structure is used to drive the pump body 11 to suck in and squeeze out the liquid in the connecting tube 16 .

[0041] When in use, the driving structure drives the large gear 4 to rotate, and the oil storage structure provides lubricating oil to the large gear 4. The rotation of the large gear 4 will operate through the transmission structure, thereby generating suction and thrust inside the pump body 11, so that the liquid is drawn into the pump body 11 through the connecting tube 16, and then squeezed out through the water outlet joint 13, and then the teeth are cleaned through the nozzle.

[0042] The design of the oil storage structure enables the large gear 4 to have a special oil storage position, so that the lubricating oil inside is not easy to be thrown out, and it can continuously provide lubricating oil during the meshing process, thereby increasing its service life. The transmission structure is driven by the rotation of the large gear 4, making it more stable to transport liquid and more powerful.

[0043] like Figure 4 As shown, the oil storage structure includes an oil storage tank 15 opened on the large gear 4;

[0044] The oil storage tank 15 is provided at the gear ring on the large gear 4, thereby dividing the entire gear ring into two parts.

[0045] The lubricating oil is applied to the oil storage tank 15 on the large gear 4, and the lubricating oil is provided for lubrication during the meshing and rotating process of the large gear 4.

[0046] Through the design of the oil storage tank 15, even after the oil storage tank 15 is opened, it will not affect the meshing of the large gear 4, and compared with the traditional method of directly applying lubricating oil on the large gear 4, since the oil storage tank 15 is lower than the teeth on both sides, the teeth on both sides will block the lubricating oil, making it difficult for it to be thrown away due to rotation, so that there is oil in the meshing process of the large gear 4, thereby increasing the service life and relatively reducing the meshing noise.

[0047] like Figure 1As shown, the driving mechanism includes a motor 2 mounted inside the housing 1, and a pinion 3 is fixedly connected to the output end of the motor 2, and the pinion 3 is meshed with a large gear 4;

[0048] The small gear 3 and the large gear 4 are tooth-meshing structures.

[0049] The motor 2 drives the small gear 3 to rotate, and the small gear 3 meshes with the large gear 4 to drive the large gear 4 to rotate.

[0050] Through the design of the motor 2 and the small gear 3, the motor 2 can continuously and stably provide power to the large gear, and the motor 2 is small in size, does not take up space, and can output a large torque and power, while being energy-saving and environmentally friendly.

[0051] like Figure 1 and 2 As shown, the transmission structure includes a shaft rod 5 fixedly connected to the inner wall of the housing 1, an eccentric sleeve 6 fixedly connected to the large gear 4, and the eccentric sleeve 6 is sleeved on the shaft rod 5;

[0052] The eccentric sleeve 6 includes a central sleeve and an eccentric ring fixedly connected to the central sleeve, and the center of the eccentric ring deviates from the center of the large gear 4;

[0053] The transmission structure also includes a sleeve 7 movably sleeved on the large gear 4, a connecting rod 8 is fixedly connected to the side wall of the sleeve 7, one end of the connecting rod 8 is fixedly connected to a piston 10, and the piston 10 is slidably connected to the inside of the pump body 11;

[0054] The pump body 11 is fixedly connected to the housing 1 through a bracket 12;

[0055] The sliding sleeve 7 is also provided with a sliding groove 9, and the shaft 5 is located in the sliding groove 9;

[0056] The eccentric sleeve 6 is in conflict with the inner wall of the sliding sleeve 7 .

[0057] In summary, during the rotation of the large gear 4, the eccentric sleeve 6 will be driven to rotate synchronously, and the eccentric sleeve 6 will resist the inner wall of the sleeve 7 to drive the sleeve 7 to reciprocate, and during the sliding of the sleeve 7, the shaft 5 will slide along the slide groove 9 to limit the sliding position of the sleeve 7, and during the sliding of the sleeve 7, the piston 10 will be pulled by the connecting rod 8 to slide inside the pump body 11, so that suction and thrust are generated inside the pump body 11, so that the liquid inside the connecting tube 16 is drawn in, and then pushed out to the water outlet joint 13.

[0058] By cooperating with the eccentric sleeve 6 and the sliding sleeve 7, an eccentric wheel structure is formed, which effectively utilizes the rotation force of the large gear 4 to drive the sliding sleeve 7 to reciprocate. No additional power structure is required, which reduces the production cost and makes the overall transmitted force more stable. Reinforcing ribs are also provided on the connecting rod 8 to strengthen the strength of the connecting rod 8 and prevent the connecting rod 8 from easily breaking and collapsing during use.

[0059] like Figure 1 As shown, the water outlet joint 13 is also provided with a plug joint, and one end of the connecting pipe 16 is plugged with a sealing plug 17;

[0060] An annular groove is provided on the plug connector, and a sealing ring 14 is sleeved in the annular groove.

[0061] The water outlet connector 13 can be connected to the nozzle of the toothbrush, and the sealing plug 17 is used to seal the other end of the connecting tube 16. When in use, the sealing plug 17 can be pulled out to connect the water and the connecting tube 16.

[0062] The sealing ring 14 is provided to ensure the tightness of the connection between the water outlet joint 13 and the nozzle, thereby avoiding water leakage, ensuring sufficient pressure, better impact effect, and cleaner teeth washing. The sealing plug 17 is provided to protect the connecting tube 16, thereby preventing foreign objects from entering the connecting tube 16 when not in use and causing blockage of the connecting tube 16.

[0063] like Figure 1 As shown, the housing 1 is divided into two half-shell structures, and the two half-shells are fixedly connected by bolts 18;

[0064] Ear plates are fixedly connected to the two half shells, and bolts 18 are threadedly connected to the two ear plates.

[0065] During installation, the two housings 1 are butted together, the ear plates are then aligned, and the bolts 18 are then screwed into the two ear plates, thereby fixing the two half shells together to form a complete housing 1.

[0066] By designing the shell 1 to be split, the shell 1 can be disassembled for maintenance when the internal components are damaged. Compared with partial disassembly, the entire shell 1 is divided into two, the exposed area is wider, and the maintenance and repair is simpler and more convenient, thereby improving the efficiency of maintenance and indirectly increasing the service life of the equipment.

[0067] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
