[0029] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0030] Example

[0031] like Figure 1 , 2 As shown, this embodiment discloses an electric nasal sprayer, which includes a nasal sprayer body 2 and a liquid spraying structure arranged at the upper end of the nasal sprayer body 2. The nasal sprayer body 2 is provided with an air pump 9 and a control circuit module 10 electrically connected to the air pump 9. The control circuit module 10 is used to control the operation of the air pump 9. The air outlet end of the air pump 9 is connected to the liquid spraying structure.

[0032] The liquid spraying structure comprises: an upper cover 3, an outer sleeve 7, an upper cover 5 and a nasal spray head 4. The upper cover 3 is mounted on the upper end of the nasal spray body 2, and an upwardly inclined jet pipe 8 is arranged on the upper cover 3. The air pump 9 in the nasal spray body 2 is connected to the jet pipe 8 through a joint, so that the airflow generated by the air pump 9 when working can flow along the jet pipe 8 and be sprayed from the nozzle of the jet pipe 8. The outer sleeve 7 is sleeved on the outside of the jet pipe 8, and the diameter of the outer sleeve 7 is slightly larger than the diameter of the jet pipe 8, so a liquid spraying gap is formed between the outer sleeve 7 and the jet pipe 8. When set, the nozzle of the jet pipe 8 extends to the nozzle position of the outer sleeve 7. When the airflow generated by the air pump 9 when working is sprayed through the jet pipe 8 and the nozzle of the outer sleeve 7, a negative pressure is generated in the liquid spraying gap due to the rapid flow of the airflow.

[0033] The upper cover 5 is mounted on the upper cover 3, and a seal can be provided between the upper cover 5 and the upper cover 3. The nasal spray head 4 is mounted on the upper cover 5, and similarly, a seal can be provided between the nasal spray head 4 and the upper cover 5. Through the above structure, the nasal spray head 4, the upper cover 5 and the upper cover 3 together enclose a liquid storage chamber 6, and the liquid storage chamber 6 is used to store liquid for cleaning the nasal cavity. The jet tube 8 and the outer sleeve 7 are located inside the liquid storage chamber 6, and the outer sleeve 7 and the jet tube 8 both extend to the nozzle position of the nasal spray head 4, and the liquid spray gap is connected to the liquid storage chamber 6. When the airflow generated by the air pump 9 is working and sprayed from the jet tube 8, a negative pressure is generated in the liquid spray gap, so that the liquid in the liquid storage chamber 6 is sucked into the liquid spray gap and sprayed from the nozzle of the nasal spray head 4 to clean the patient's nasal cavity.

[0034] During the specific setting, the nasal spray tip 4 is tilted so that the nasal spray tip 4 conforms to the ergonomic design and improves the patient's comfort.

[0035] In addition, a waste liquid collection cover 1 is arranged on the outer side of the upper cover 5. After the patient cleans the nasal cavity, the waste liquid flowing out of the nasal cavity falls into the waste liquid collection cover 1 and is collected. In the specific configuration, the waste liquid collection cover 1 is provided with an arc surface on the side facing the human body. When in use, the arc surface can fit the human body so that the waste liquid collection cover 1 can better collect the waste liquid flowing out of the nasal cavity.

[0036] like Figure 3 As shown, the control circuit module 10 includes: a MOS switch module, an oscillation module, a controller, a storage module, a switch and a lithium battery. Among them, the MOS switch module is connected to the air pump 9, which is used to control the operation of the air pump 9, that is, when the MOS switch module is turned on, the air pump 9 starts to work, and when the MOS switch module is turned off, the air pump 9 stops working. The oscillation module is connected to the MOS switch module, which is used to output a pulse width modulation signal to the MOS switch module to control the switch state of the MOS switch module. The controller is connected to the oscillation module, which is used to control the operation of the oscillation module. It can call the pulse width modulation signal parameters of the oscillation module when it worked last time, and control the oscillation module to use the pulse width modulation signal parameters of the last time it worked when it worked next time. The storage module is connected to the controller, which is used to store the pulse width modulation signal parameters output when the oscillation module works. The lithium battery is connected to the controller, which is used to power each module. The switch is connected to the controller, which is used to send a start-stop signal to the controller. When set, the switch can be set on the outer wall of the nasal spray body 2, which is convenient for users to operate.

[0037] The user presses the switch to send a start signal to the controller, and the controller controls the oscillation module to send a pulse width modulation signal to the MOS switch module. The MOS switch module conducts the air pump 9, and the air pump 9 starts to work. The liquid medicine is sprayed from the nasal spray head 4 to clean the patient's nasal cavity. When working next time, the controller calls the pulse width modulation signal parameters of the oscillation module when it last worked from the storage module, and controls the oscillation module to use the pulse width modulation signal parameters of the last work to control the action of the MOS switch module, so that the air pump 9 works according to the last working state, so that the water flow pressure of the electric nasal sprayer tends to be the same each time it works, and improves the user's experience.

[0038] In addition, if Figure 3 As shown, the control circuit module 10 also includes a Usb type-c module and a charging management module; the Usb type-c module is connected to the charging management module, and the charging management module is connected to the lithium battery. The lithium battery can be charged through the Usb type-c module and the charging management module, so that the lithium battery can be used repeatedly.

[0039] Furthermore, the control circuit module 10 further comprises a charging indicator light and a status indicator light, both of which are connected to the controller. The charging indicator light and the status indicator light can display the working status of the electric nasal sprayer.

[0040] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any way.

[0041] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the present invention, and these solutions also belong to the disclosure scope of the present invention and fall within the protection scope of the present invention. Those skilled in the art should understand that the present invention description and its drawings are illustrative and do not constitute a limitation of the claims.
