Description

Handheld tooth cleaner with easy nozzle replacement

[0001] The present invention relates to the technical field of tooth cleaners, and in particular to a handheld tooth cleaner with a convenient nozzle replacement.

[0002] Tooth scalers are widely recognized as an important oral cleaning tool. They effectively clean the gum sulcus and interdental spaces, removing impurities that are difficult to remove with traditional toothbrushes. They also effectively clean various crevices, holes, and uneven surfaces on the tooth surface. The water jet from the tooth scaler also massages the gums, promoting blood circulation and enhancing local tissue resistance to disease.

[0003] However, the existing toothbrush nozzle and the body are usually connected by an interference fit. After long-term use, the tightness of the connection between the nozzle and the body will deteriorate. In addition, when the nozzle is subjected to external force, the interference fit connection method will cause the nozzle to deflect, thereby causing the direction of the ejected water flow to deflect. In addition, during the flushing process, some medicine powder will be added to the water. If the medicine powder is not completely dissolved, it is easy to cause blockage of the body and the pipeline. Therefore, a handheld toothbrush with easy nozzle replacement is proposed.

[0025]

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026]

[0026] Please refer to -, the present invention provides a technical solution: a handheld toothbrush that is easy to replace the nozzle, including a toothbrush body 1, a groove 11 is opened on the top of the toothbrush body 1, a connecting component 2 is fixedly installed in the groove 11, a nozzle mechanism 3 is detachably installed in the connecting component 2, and the nozzle mechanism 3 is assembled and connected to the connecting component 2 by pressing, and a pot body 4 is detachably installed at the bottom of the toothbrush body 1, a connecting pipe 12 is provided at the bottom of the toothbrush body 1, a hose 5 is sleeved on the connecting pipe 12, and an anti-blocking mechanism 6 is installed at one end of the hose 5 away from the connecting pipe 12.

[0027]

[0027] The connecting assembly 2 includes a connecting head 21, a circular groove 22 is opened on the connecting head 21, the connecting head 21 is fixedly connected to the inner wall of the groove 11, a circular tube 23 is fixedly installed on the connecting head 21, the circular groove 22 and the circular tube 23 are coaxially arranged, the connecting tube 12 is connected to the circular tube 23, and the nozzle mechanism 3 includes a nozzle body 31, a connecting cylinder 32 is fixedly installed at the bottom of the nozzle body 31, an annular plate 33 is rotatably installed at the bottom of the connecting cylinder 32, and a connecting ring block 34 is fixedly installed on the top of the annular plate 33. The connecting ring block 34 is connected to the inner wall of the connecting cylinder 32 by interference fit, and the circular tube 23 is connected to the inner wall of the circular tube 23 by transition fit.

[0028]

[0028] An annular push plate 25 is provided on the outer sliding sleeve of the circular tube 23, and the annular push plate 25 is slidably connected to the inner wall of the circular groove 22. A return spring 26 is fixedly installed at the bottom of the annular push plate 25, and the bottom end of the return spring 26 is fixedly connected to the inner wall of the bottom of the circular groove 22. The return spring 26 is slidably sleeved on the circular tube 23, and a hollow elastic sealing ring 36 is provided on the outer sliding sleeve of the connecting tube 32. The top of the hollow elastic sealing ring 36 is tightly connected to the bottom of the nozzle body 31.

[0029]

[0029] Further, when the annular plate 33 is stuck in the circular groove 22, the circular tube 23 is tightly connected to the inner wall of the connecting ring block 34. At this time, the water in the circular tube 23 completely enters the connecting tube 32 and will not leak out.

[0030]

[0030] The hollow elastic sealing ring 36 can not only play a tensioning role between the nozzle body 31 and the connector 21 to ensure that the nozzle body 31 does not shake, but also play a sealing role. When the nozzle body 31 is pressed to separate the nozzle mechanism 3 from the connecting component 2, the hollow elastic sealing ring 36 will be deformed.

[0031]

[0031] The side of the annular plate 33 is embedded and rotatably mounted with multiple rollers 35 distributed in a circular array. The inner wall of the circular groove 22 is provided with multiple clamping mechanisms 24 distributed in a circular array. The multiple clamping mechanisms 24 are respectively adapted to the corresponding rollers 35. The clamping mechanism 24 includes a guide groove 1 241 and a guide groove 2 242 opened on the inner wall of the circular groove 22. The bottoms of the guide groove 1 241 and the guide groove 2 242 are connected, and the guide groove 1 241 and the guide groove 2 242 are arranged in a V shape.

[0032]

[0032] The clamping mechanism 24 further includes an indicator arrow 246 opened on the top of the connector 21, and the indicator arrow 246 points toward the top opening of the guide groove 241.

[0033]

[0033] Furthermore, the indicating arrow 246 can be used to facilitate accurate insertion of the roller 35 into the guide groove 1 241.

[0034]

[0034] The anti-blocking mechanism 6 includes a boss 61, a clamping tube 62 is provided on the boss 61, the clamping tube 62 is interference fit with the inner wall of the hose 5, a cavity 63 is provided on the boss 61, the clamping tube 62 is connected to the cavity 63, and a conical filter cartridge 64 is fixedly sleeved on the side of the boss 61, and the bottom of the conical filter cartridge 64 is sealed.

[0035]

[0035] The outside of the conical filter cartridge 64 is wrapped with a conical cover 65, and the conical cover 65 and the conical filter cartridge 64 are fixedly connected by a plurality of connecting rods 66 distributed in a circular array. The outer side of the conical filter cartridge 64 is fixedly sleeved with an annular sealing ring 2 68, and an annular sealing ring 1 67 is fixedly installed on the inner wall of the conical cover 65. The cross-sections of the annular sealing ring 1 67 and the annular sealing ring 2 68 are V-shaped.

[0036]

[0036] A hollow bracket 611 is fixedly installed in the cavity 63, and a circular shaft 610 is rotatably installed on the hollow bracket 611. An impeller 612 is rotatably installed in the cavity 63. The circular shaft 610 is fixedly connected to the impeller 612. The bottom end of the circular shaft 610 extends through the outside of the bottom of the conical filter cartridge 64, and a plurality of scraping strips 69 distributed in a circular array are fixedly installed at the bottom end of the circular shaft 610. The plurality of scraping strips 69 are all slidably connected to the outer side of the conical filter cartridge 64.

[0037]

[0037] Furthermore, the tooth cleaner body 1 is not used vertically during use. When the tooth cleaner body 1 is tilted, the water in the pot body 4 will accumulate on the tilted side. Under the counterweight of the anti-blocking mechanism 6, the bottom opening of the conical cover 65 can be completely immersed in water, thereby ensuring that the water in the pot body 4 can be completely extracted.

[0038]

[0038] In this embodiment, when using, when replacing a new nozzle body 31, first sleeve the hollow elastic sealing ring 36 on the connecting tube 32, and push the hollow elastic sealing ring 36 upward to fit the bottom of the nozzle body 31. Then, insert the connecting ring block 34 into the bottom of the connecting tube 32 and fit the bottom of the connecting tube 32 to the annular plate 33.

[0039]

[0039] Then, multiple rollers 35 are inserted into the corresponding guide grooves 241 and the entire nozzle mechanism 3 is pushed downward. During this process, the annular plate 33 is fitted with the annular push plate 25. As the annular plate 33 pushes the annular push plate 25 downward, the return spring 26 is compressed. When the rollers 35 reach the bottom, the nozzle body 31 is released. Then, the compressed return spring 26 pushes the annular plate 33 upward. During the upward movement of the annular plate 33, the rollers 35 are stuck into the slots 243 along the guide slope 244. At this time, the connecting assembly 2 and the nozzle mechanism 3 are tightly connected together.

[0040] When removing the nozzle mechanism 3 from the connecting assembly 2, the nozzle body 31 is pressed again, causing the multiple rollers 35 to simultaneously move downward and out of the corresponding slots 243. During the downward movement of the rollers 35, they will move downward along the second guide slope 245. During the above process, the return spring 26 will be compressed. Then, the nozzle body 31 is released, and the rollers 35 will move upward along the second guide groove 242. Then, the nozzle body 31 is pulled again to remove the multiple rollers 35 from the corresponding second guide groove 242.

[0041] When rinsing the interdental spaces, the toothbrush body 1 is activated, which creates a negative pressure in the hose 5. The water in the pot body 4 enters the clamping tube 62 through the bottom opening of the conical cover 65, is filtered by the conical filter cartridge 64, and then enters the hose 5 through the cavity 63 and the clamping tube 62. The water then enters the circular tube 23 through the connecting tube 12 and is ejected through the nozzle body 31.

[0042]

[0042] When water passes through the cavity 63, it drives the impeller 612 to rotate. The impeller 612 then drives the multiple scraping bars 69 to rotate through the circular shaft 610. The multiple scraping bars 69 can scrape off the undissolved medicine attached to the conical filter cartridge 64 during the rotation process. When the water flows upward from the bottom of the conical cover 65, it will generate thrust on the annular sealing ring 1 67 and the annular sealing ring 2 68. After the annular sealing ring 1 67 and the annular sealing ring 2 68 are deformed by the force, the water will carry some undissolved medicine and be discharged from the gap between the annular sealing ring 1 67 and the annular sealing ring 2 68;

[0043]

[0043] The rotating scraper 69 can stir the undissolved medicine stuck between the conical filter cartridge 64 and the conical cover 65 and not discharged in time, so that the undissolved medicine is fully dissolved and then discharged through the conical filter cartridge 64.

[0044] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
