[0037] Patent CN215503503U (application number: 202120994119.0) discloses a water flosser with ultrasonic atomization function. The water flosser is equipped with an atomizing device that humidifies the teeth, achieving a spray-humidification effect. Water is then pumped from a tank using a high-pressure water pump to clean the teeth. The humidification enhances the cleaning effect. However, this water flosser can only use the water for flossing to spray onto the teeth and cannot meet the purpose of individual dental care.

[0038] Based on the above reasons, this application provides a dental flosser with an oral spray. The flossing component and the spray component are independent of each other and can be detached from each other. The flossing component can supply power to the spray component, so that the flossing component and the spray component can use different liquids to care for the teeth. In particular, after rinsing the teeth, the spray component can use different liquids to care for the oral cavity and teeth, which improves the effectiveness of the dental flosser and enhances its flexibility and modularity.

[0039] In some scenarios, when using the oral spray-equipped dental flosser in this application embodiment, the oral cavity can be sprayed first through the spray component, and then the oral cavity and teeth can be rinsed through the rinsing component to achieve the purpose of oral cleaning and care.

[0040] In other scenarios, when using the oral spray-equipped dental flosser in this application embodiment, the oral cavity and teeth can first be cleaned through the oral rinsing component, and then sprayed through the spray component to achieve the purpose of caring for the teeth and oral cavity.

[0041] The following describes a dental flosser with an oral spray provided in this application, using specific examples.

[0042] like Figures 1 to 3 As shown in the embodiment of this application, a dental flosser with an oral spray includes a flossing assembly 100 and a spray assembly 200. The spray assembly 200 is detachably connected to the flossing assembly 100. The flossing assembly 100 can supply power to the spray assembly 200, and the spray assembly 200 is used to generate a spray.

[0043] Specifically, the oral irrigator provided in this application embodiment is configured with a relatively independent structure for the rinsing component 100 and the spray component 200. The rinsing component 100 is used to rinse the teeth and oral cavity, and the spray component 200 is used to spray the oral cavity and teeth.

[0044] The oral irrigating assembly 100 and the spray assembly 200 can be used to clean and care the oral cavity by using different liquids, respectively, so that the selection possibility of the liquid used for cleaning and caring the oral cavity is improved, and the cleaning and caring effect of the oral cavity is improved. The oral irrigating assembly 100 and the spray assembly 200 are arranged in a mutually independent structure, the oral irrigating assembly 100 can supply power to the spray assembly 200, and the spray assembly 200 can be removed from the oral irrigating assembly 100 when the oral irrigating assembly 100 is used, so that the oral irrigating assembly 100 can relatively independently perform oral irrigation. When the spray assembly 200 is mounted on the oral irrigating assembly 100, the spray assembly 200 can be powered by the oral irrigating assembly 100 to spray the oral cavity, thereby achieving spray care of the oral cavity.

The power supply contact 101 is used to supply power to the spray unit 220.

[0047] In use, the oral irrigating assembly 100 can achieve oral irrigation, and after the spray assembly 200 is mounted, the spray assembly 200 can be conveniently electrically connected with the oral irrigating assembly 100 through the power supply contact 101, so that the convenience of use of the present application is improved, the cable is not needed for electrical connection, the modular degree of the present application is improved, and the user experience is improved.

[0048] In some implementations, the bottom of the spray unit 220 can be provided with a mounting plate to improve the mounting stability of the spray unit 220.

[0049] In some implementations, one end of the connecting cover 210 is provided with an opening portion 211 forming an opening structure, and the opening portion 211 can be sleeved and connected to or removed from one end of the oral irrigating assembly 100.

[0050] Specifically, as shown in Figures 3 to 5 The opening portion 211 can conveniently buckle the connecting cover 210 on the oral irrigating assembly 100.

[0051] In use, when the connecting cover 210 is fastened to the water flossing assembly 100, it is only necessary to fasten the connecting cover 210 to one end of the water flossing assembly 100.

The spray PCBA 223 is electrically connected to the spray blade 222. The spray PCBA 223 is provided with a spray switch 224. The connecting cover 210 is provided with a spray button 225 that abuts against the spray switch 224.

[0053] Specifically, the spray plate 222 is an ultrasonic spray plate, which can convert water flow into ultrasonic spray through ultrasonic oscillation when an electric current is applied.

[0054] Specifically, such as Figures 3 to 5 As shown, the water storage tank 221 is used to store the liquid used to generate the spray, the spray blade 222 is used to directly generate the spray, the spray PCBA 223 is used to control the spray blade 222, the spray PCBA 223 is electrically connected to the spray blade 222, the water inlet 213 is used to add the spray liquid into the water storage tank 221, the spray nozzle 212 is used to guide the spray out, the spray switch 224 is used to control the working state of the spray blade 222, and the spray button 225 is used to press the spray switch 224 to open and close.

[0055] In this embodiment, spray liquid is added to the water storage tank 221 through the water inlet 213. The spray assembly 200 is then fastened to the rinsing assembly 100, which supplies power to the spray assembly 200. The user presses the spray button 225 to turn on the spray switch 224, causing the spray PCBA 223 to control the spray blade 222 to start working, generating a spray. The spray is then expelled from the spray nozzle 212, achieving the purpose of oral spray care using the spray assembly 200. During use, the spray assembly 200 can use independent spray liquids, allowing for the use of different liquids for rinsing and spraying, increasing the flexibility in selecting the liquid for oral care and improving the cleaning and care effect on the oral cavity.

[0056] In some implementations, the water inlet 213 and the spray button 225 are located on the top of the connecting cover 210, and the spray nozzle 212 is located on the side wall of the connecting cover 210.
