Description

Technical Field

[0001] The present invention relates to the field of nasal washers, and particularly to a positive and negative pressure electric nasal cavity cleaner. Background Art

[0002] A nasal washer is a tool for flushing the nasal cavity. It usually uses a certain pressure (either suction, or gravity, or mechanical pressure) to send physiological saline into the nostrils, flowing through the nasal vestibule (the part exposed outside the head), the nasal sinuses, the nasal passages, around the nasopharynx, and either discharging from one nostril or from the mouth. The structure of the nasal washer is referred to the one disclosed in the patent document with the publication number CN106265042B. It sends the cleaning liquid into the nasal cavity through a water pump. In this solution, the cleaning liquid will pass through the water pump and then be sent into the nasal cavity. After long-term use, the cleaning liquid is likely to remain in the water pump, and bacteria will breed in the water pump and enter the nasal cavity along with the cleaning liquid, causing pollution. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a positive and negative pressure electric nasal cavity cleaner, in which the air-liquid passage is completely separated, so that the cleaning liquid and the waste liquid do not pass through any motors or concealed pipelines, and the liquid storage tank and the liquid pipeline can be completely disassembled and cleaned without bacterial growth.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a positive and negative pressure electric nasal cavity cleaner, including a flushing cover, a vacuum pump, a cleaning liquid storage tank and a waste liquid storage tank;

[0005] The flushing cover is provided with a liquid outlet and a liquid return port corresponding to two nostrils,

[0006] The gas output port of the vacuum pump is communicated with the cleaning liquid storage tank;

[0007] The inner end of the liquid outlet is communicated with the inside of the cleaning liquid storage tank through a liquid outlet pipe;

[0008] The inner end of the liquid return port is communicated with the waste liquid storage tank;

[0009] The top of the waste liquid storage tank is communicated with the gas input port of the vacuum pump through a return air pipe.

[0010] When in use, the liquid outlet and the liquid return port are aligned with the two nostrils, and the air flow output port of the vacuum pump is connected to the cleaning liquid chamber, used to compress the gas into the cleaning liquid chamber. At this time, the pressure in the cleaning liquid chamber is greater than the ambient pressure, which prompts the cleaning liquid to flow out along the liquid outlet pipe, realizing the delivery of the cleaning liquid to the liquid outlet, enabling the cleaning liquid to enter both nasal cavities through one nostril and then flow into the waste liquid chamber along the liquid return port from the other nostril. The gas input port of the vacuum pump is connected to the waste liquid chamber, used to discharge the gas in the waste liquid chamber by suction. As the gas in the chamber is discharged, the air pressure in the chamber gradually becomes less than the external atmospheric pressure, forming a negative pressure state, which helps to accelerate the cleaning and discharge of the cleaning liquid in the nasal cavity into the waste liquid chamber, achieving a state of pressure balance in the nasal cavity, making the flow rate of the cleaning liquid faster. The technical principle of combining flushing and suction makes the cleaning efficiency higher.

[0011] This technical principle is positive pressure pumping and negative pressure suction, which completely separates the gas-liquid passage, so that the cleaning liquid and the waste liquid do not pass through any motors or concealed pipelines, and the liquid chamber and the liquid pipeline can be completely cleaned without bacterial growth.

[0012] Preferably, the flushing cover is made of integral silica gel, and a dust-proof cover is fitted on the flushing cover. It improves the integrity, ensures the stability of the structure, and the silica gel material is more comfortable to contact with the skin. The dust-proof cover improves the cleanliness of the flushing cover.

[0013] Preferably, the vacuum pump is located in the main body section, the waste liquid chamber is arranged above the main body section, the upper port of the waste liquid chamber is buckled with the flushing cover, and the cleaning liquid chamber is arranged below the main body section. The layout is more reasonable, which can more conveniently pump and deliver the cleaning liquid while recycling the waste liquid.

[0014] Preferably, both ends of the liquid outlet pipe are detachably connected to the liquid outlet and the cleaning liquid chamber respectively. It is convenient for disassembly and cleaning.

[0015] Preferably, a top cavity is arranged on the inner wall of the flushing cover, the upper end of the return air pipe extends into the top cavity, and a gap is left between the return air pipe and the top cavity. Interference fit can prevent water from passing through the high-elastic layer under normal pressure. The high-elastic layer can enable the gas to pass through normally when the pressure difference on both sides is large, that is, the negative pressure of the vacuum pump can break through the gap between the high-elastic layer and the return air pipe, making the waste liquid chamber form a negative pressure state.

[0016] Preferably, a positive pressure relief branch pipe communicating with the atmosphere is arranged at the gas output port, and a positive pressure regulating valve is arranged on the positive pressure relief branch pipe. In case of poor pipeline circulation, resulting in excessive pressure at the gas output port, the positive pressure regulating valve can be opened or increased to relieve the pressure to a certain extent.

[0017] Preferably, a negative pressure relief branch pipe communicating with the atmosphere is provided at the gas input port, and a negative pressure regulating valve is provided on the negative pressure relief branch pipe. When the pipeline is blocked, resulting in too low pressure at the gas output port, the negative pressure regulating valve can be opened or the opening degree can be increased to relieve the pressure to a certain extent.

[0018] Preferably, it includes a main body section, in which a battery, a circuit board and the vacuum pump are electrically connected to each other, and the circuit board is provided with control buttons; a silica gel key sleeve is arranged outside the control buttons. The stability of its electronic components is improved, and the silica gel key sleeve can improve the waterproof effect.

[0019] Preferably, the clean liquid tank is arranged below the main body section, and the waste liquid tank is arranged above the main body section. It is convenient to recycle the waste liquid generated by cleaning.

[0020] Preferably, a sealing ring is arranged between the clean liquid tank and the main body section, and a capacity scale is arranged on the outer surface of the clean liquid tank. It is convenient to directly know the amount of the internal cleaning liquid.

[0021] Advantages of the present invention:

[0022] Based on the principle of using a vacuum pump to draw gas from one side to the other side, only one air pump is needed to achieve the effect of simultaneously providing positive pressure and negative pressure, and the gas-liquid passage is completely separated, so that the cleaning liquid and the waste liquid do not pass through any motors or concealed pipelines, and the liquid tank and the liquid pipeline can be completely disassembled and cleaned without the growth of bacteria.

[0031] Embodiment

[0032] As Figure 1 shown, the positive and negative pressure electric nasal cavity cleaner includes a flushing cover 1, a vacuum pump 18, a clear liquid tank 4, and a waste liquid tank 5; the flushing cover 1 is provided with a liquid outlet 2 and a liquid return port 3 corresponding to two nostrils, and the gas output port 8 of the vacuum pump 18 is communicated with the clear liquid tank 4; the inner end of the liquid outlet 2 is communicated to the inside of the clear liquid tank 4 through a liquid outlet pipe 6; the inner end of the liquid return port 3 is communicated with the waste liquid tank 5; the top of the waste liquid tank 5 is communicated to the gas input port 9 of the vacuum pump 18 through a gas return pipe 7.

[0033] When in use, the liquid outlet 2 and the liquid return port 3 are aligned with two nostrils, and the air flow output port of the vacuum pump 18 is communicated with the clear liquid tank 4, which is used to compress gas into the clear liquid tank 4. At this time, the pressure in the clear liquid tank 4 is greater than the ambient pressure, which prompts the cleaning liquid to flow out along the liquid outlet pipe 6, so as to deliver the cleaning liquid to the liquid outlet 2, enabling the cleaning liquid to enter both nasal cavities through one nostril and then flow into the waste liquid tank 5 along the liquid return port 3 from the other nostril. The gas input port 9 of the vacuum pump 18 is communicated with the waste liquid tank 5, which is used to discharge the gas in the waste liquid tank 5 by suction. As the gas in the tank is discharged, the air pressure in the tank gradually becomes less than the external atmospheric pressure, forming a negative pressure state, which helps to accelerate the cleaning and discharge of the cleaning liquid in the nasal cavity into the waste liquid tank 5, achieving a state of pressure balance in the nasal cavity, making the flow rate of the cleaning liquid faster, and the technical principle of combining flushing and suction makes the cleaning efficiency higher.

[0034] This technical principle is positive pressure pumping and negative pressure suction, which completely separates the gas-liquid path, so that the cleaning liquid and the waste liquid do not pass through any motors or hidden pipelines, and the liquid tank and the liquid pipeline can be completely cleaned without the growth of bacteria.

The upper end of the gas return pipe 7 extends into the top cavity 11, and a gap is left between the gas return pipe 7 and the top cavity 11. Interference fit can prevent water from passing through the high-elastic layer under normal pressure. When the pressure difference on both sides is large, the gas can pass through normally, that is, the negative pressure of the vacuum pump 18 can break through the gap between the high-elastic layer and the gas return pipe 7, making the waste liquid tank 5 in a negative pressure state.

[0040] A positive pressure relief branch pipe 12 communicating with the atmosphere is arranged at the gas output port 8, and a positive pressure regulating valve 13 is arranged on the positive pressure relief branch pipe 12. When the pipeline is blocked and the pressure at the gas output port 8 is too high, the positive pressure regulating valve 13 can be opened or increased to relieve the pressure to a certain extent.

[0041] A negative pressure relief branch pipe 14 communicating with the atmosphere is arranged at the gas input port 9, and a negative pressure regulating valve 15 is arranged on the negative pressure relief branch pipe 14. When the pipeline is blocked and the pressure at the gas output port 8 is too low, the negative pressure regulating valve 15 can be opened or increased to relieve the pressure to a certain extent.

[0042] It includes a main machine section 16. A battery, a circuit board 17 and the vacuum pump 18 which are electrically connected to each other are arranged in the main machine section 16. A control button 19 is arranged on the circuit board 17; a silica gel key sleeve 20 is arranged outside the control button 19. The stability of its electronic components is improved, and the silica gel key sleeve 20 can improve the waterproof effect.

[0044] A sealing ring is arranged between the clear liquid tank 4 and the main machine section 16, and a capacity scale is arranged on the outer surface of the clear liquid tank 4. It is convenient to directly know the amount of the internal cleaning liquid.

[0045] The beneficial effects of the present invention:

[0046] This solution utilizes the principle of using a vacuum pump 18 to pump gas from one side to the other side. Only one air pump needs to be set up to achieve the effect of simultaneously providing positive pressure and negative pressure, and the gas-liquid passage is completely separated, so that the cleaning liquid and waste liquid do not pass through any motors or concealed pipelines, and the liquid storage tank and liquid pipeline can be completely disassembled and cleaned without the growth of bacteria.
