[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not 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 efforts are within the scope of protection of the present invention.

[0041] Example 1

[0042] As attached Figure 1 -Attached Figure 8 The nasal washer shown includes a main unit 1 and a flushing assembly 2. The main unit 1 includes, from top to bottom, a water storage tank 11, a shell 12, and a waste water tank 13. The water storage tank 11 is used to store water or liquid medicine, and the waste water tank 13 is used to store sewage after flushing the nasal cavity. A plug-in end 105 is provided on the shell 12, and the flushing assembly 2 is plugged in and detachably connected to the plug-in end 105. At least two inlet and outlet water pipes 153 with a certain length and flexibility are provided between the flushing assembly 2 and the plug-in end 105. The inlet and outlet water pipes 153 are silicone water pipes or spring telescopic water pipes. The flushing assembly 2 can be pulled out to perform the nasal flushing operation away from the main unit 1, thereby preventing the host 1 from being wetted by falling water.

[0043] In this way, when the length of the inlet and outlet water pipes 153 is set to 20CM or greater than 20CM, the flushing component 2 can be pulled out and moved at least 20CM away from the main unit. When the flushing component 2 is pulled out, the flushing component 2 can be rotated to swap the directions of the water outlet and the return water outlet on the flushing component 2, thereby achieving flushing of the left and right nasal cavities. It is very convenient to use. For example, the initial state of the flushing component 2 is that the hole on the left is the water outlet and the hole on the right is the return water outlet. After rotating the flushing component 180 degrees, the hole on the left is the return water outlet and the hole on the right is the water outlet.

[0044] In some embodiments, as shown in the attached Figure 4As shown, the host 1 also includes a positive and negative pressure device arranged inside the shell 12, which is used for inflating and pressurizing the water storage tank 11 and draining the negative pressure water backflow of the wastewater tank 13, so as to increase the water pressure of the flushing water flow of the flushing component 2 and quickly suck the sewage after flushing the nasal cavity into the wastewater tank 13. The positive and negative pressure device includes a positive and negative pressure air pump 121 and an air flow regulating valve 122. The air inlet of the positive and negative pressure air pump 121 is connected to the wastewater tank 13. When the positive and negative pressure air pump 121 is started, the positive and negative pressure air pump 121 is opened to pump air into the wastewater tank 13, so that a negative pressure effect is generated in the wastewater tank 13; The air outlet of the positive and negative pressure air pump 121 is connected to one end of the air flow regulating valve 122, and the other end of the air flow regulating valve 122 is connected to the water storage tank 11. When the positive and negative pressure air pump 121 is started, air is extracted from the wastewater tank 13, and the air flow enters the air flow regulating valve 122 along the connecting pipe, and is finally discharged into the water storage tank 11, forming an inflation and pressurization effect on the inside of the water storage tank 11. The air flow regulating valve 122 is used to adjust the size of the air flow in and out of the positive and negative pressure air pump 121. The air flow regulating valve 122 includes an adjusting knob, which passes through the shell 12 and extends to the outside of the shell 12.

[0045] In some embodiments, as shown in the attached Figure 5 As shown, a circular groove 10 is provided on the upper surface of the shell 12, and a buckle or thread is provided on the side wall of the circular groove 10. The water storage tank body 11 is detachably connected to the shell 12 through the buckle or thread on the circular groove 10. A sealing ring is provided at the position where the water storage tank body 11 and the shell 12 are connected. A raised opening is provided at the position where the water storage tank body 11 and the circular groove 10 are connected. An air outlet pipe 123 is provided on the upper surface of the shell 12, and the air outlet pipe 123 is connected to the output end of the air flow regulating valve 122. When the wastewater tank 13 is connected, an inflation and pressurization effect of the water storage tank 11 is formed, and the air outlet pipe 123 extends upward through the opening to the top near the water storage tank 11. The wastewater tank 13 is detachable at the bottom of the shell 12 by snap-fit or thread. A sealing rubber ring is provided at the position where the wastewater tank 13 and the shell 12 are connected to increase its airtightness. By providing a detachable wastewater tank 13, it is convenient to disassemble and clean the wastewater tank 13. The wastewater tank 13 is provided with holes to facilitate dumping of the sewage inside.

[0046] In some embodiments, as shown in the attached Figure 5As shown, a silicone control valve 124 is provided on one side of the air outlet pipe 123. The silicone control valve 124 is a straight silicone valve or a cross silicone valve. When the silicone control valve 124 is a straight silicone valve, a straight opening is provided on the silicone control valve 124, and this opening is in a closed state under normal pressure. When the silicone control valve 124 is a cross silicone valve, a cross-shaped opening is provided on the silicone control valve 124. The top of the silicone control valve 124 passes through the opening 20 and is connected to the water storage tank body 11. The other end of the silicone control valve 124 is the water outlet end.

[0047] In this way, after the positive and negative pressure air pumps 121 are started, the positive and negative pressure air pumps 121 continuously inflate and pressurize the water storage tank 11. Since the water storage tank 11 is a closed space after being connected to the shell 12, when the air pressure inside the water storage tank 11 exceeds the pressure borne by the silicone control valve 124, the silicone control valve 124 is deformed, and its I-shaped opening or cross-shaped opening is in an open state at this time. The water or liquid medicine in the water storage tank 11 is discharged from the I-shaped opening or cross-shaped opening to the water outlet. When the positive and negative pressure air pumps 121 are turned off, the water storage tank 11 returns to normal pressure, and the opening of the silicone control valve 124 automatically closes and returns to its initial state.

[0048] In some embodiments, as shown in the attached Figure 7 As shown, a slot 1051 of a certain depth is provided on the plug end 105, and a water outlet pipe 30 and a water return pipe 40 are provided in the slot 1051. The water outlet pipe 30 extends into the water storage tank body 11 and is interconnected with the water storage tank body 11. The silicone control valve 124 is located at one end of the water storage tank body 11 on the water outlet pipe 30, and the water return pipe 40 extends into the waste water tank body 13 and is interconnected.

[0049] Furthermore, the host 1 also includes a circuit board 125, a charging socket 126, a push button switch 127 and a battery 128 arranged inside the shell 12. The charging socket 126, the push button switch 127, the battery 128 and the positive and negative pressure air pumps 121 are all electrically connected to the circuit board 125. The charging socket 126 passes through the corresponding shell 12. The push button switch 127 is provided with a button body, which passes through the shell 12 and is pressed and connected to the push button switch 127. In this embodiment, the air flow regulating valve 122, the battery 128 and the circuit board 125 are all arranged on one side of the positive and negative pressure air pump 121 in the middle position of the positive and negative pressure air pump 121, wherein the battery 128 is a rechargeable battery, which is connected to an external adapter power supply through the charging socket 126 to charge the battery 128, and the host 1 is turned on or off by controlling the push button switch 127 and the circuit board 125.

[0050] In some embodiments, as shown in the attached Figure 8As shown, a water filling port 111 is provided on the water storage tank body 11, and the water storage tank body 11 also includes a water tank cover 100 rotatably connected to the water storage tank body 11. A sealing rubber ring is provided at the position where the water tank cover 100 contacts the water filling port 111 to improve the airtightness of the water storage tank body 11 and prevent water leakage or seepage from the water storage tank body 11. When the water tank cover 100 is opened, water or liquid medicine can be added to the water storage tank body 11 through the water filling port 111. A pick position 101 is also provided on one side of the water filling port 111 to facilitate the removal of the water tank cover 100.

[0051] Example 2

[0052] As attached Figure 9 -Attached Figure 11 The flushing assembly shown in the figure further comprises a base 26 and a handle 21 detachably connected to the base 26, the base 26 comprises a holder 262, the holder 262 extends outward by a certain length to form a convex state of the holder 262, and at least two groups of card holes 50 are provided on the holder 262, and the back side of the handle 21 is designed as a groove, and a holder 20 is provided on the handle 21 opposite to the card hole 50, and the holder 20 is located in the groove of the handle 21. When the holder 262 is inserted into the groove and the holder 20 is snapped into the card hole 50, the handle 21 is in a fixed state, and the handle 21 is provided with a water outlet plug end 212 and a water return plug end 211 that are mutually connected at both ends, and the same end of the water outlet plug end 212 and the water return plug end 211 is provided with a soft conical sleeve 213, which is located at the front end of the handle 21 so that it can be aligned with the human nasal cavity when in use. There are two groups of plug interfaces 261 that are interconnected front and back, and both groups of plug interfaces 261 are provided with sealing rings. The two groups of plug interfaces 261 on the base 26 are inserted into the water outlet pipe 30 and the return water pipe 40 on the plug end 105 one by one, forming a plug-in fixed state of the base 26. In this embodiment, the return water pipe 40 is located on the side of one end inside the wastewater tank 13 and is provided with a negative pressure hole. The negative pressure hole is connected to the air inlet end of the positive and negative pressure air pump 121. When the positive and negative pressure air pump 121 is started, air is extracted in the wastewater tank 13 through the negative pressure hole. During use, the base 26 is fixed on the main unit 1. At this time, the handle 21 can be removed for operation, or it can be installed on the base 26 for operation. The other end of the water outlet plug end 212 and the return water plug end 211 are fixedly connected to the opposite end of the plug interface 261 on the base 26 through two inlet and outlet pipes 153, forming a connected state of water outlet and return water.

[0053] In this way, when the length of the holder 262 is set to 5CM or more, the handle 21 fixed on the base 26 is at least 5CM away from the host 1, reducing the probability of the host 1 being wetted by falling water or sewage. At the same time, the user can also pull out the handle 21, rotate the handle 21, and exchange the directions of the water outlet and the water return port on the handle 21, thereby achieving flushing of the left and right nasal cavities, which is very convenient to use. For example, the initial state of the handle 21 is that the hole on the left is the water outlet and the hole on the right is the water return port. After rotating the flushing assembly 180 degrees, the hole on the left is the water return port and the hole on the right is the water outlet;

[0054] When the length of the water inlet and outlet pipes 153 is set to 20CM or greater, the handle 21 can be separated from the base 26 and can be at least 20CM away from the main unit. After the handle 21 is pulled out, it can also be held in the hand for operation and use, which is very convenient.

[0055] Example 3

[0056] As attached Figure 12 , Attachment Figure 13 The flushing assembly shown in the figure further includes a handle 21, and the handle 21 is provided with a water outlet plug end 212 and a return water plug end 211 that are connected to each other at both ends. The same end of the water outlet plug end 212 and the return water plug end 211 is provided with a soft conical sleeve 213, and the soft conical sleeve 213 is located at the front end of the handle 21 so that it can be aligned with the human nasal cavity when in use. The other ends of the water outlet plug end 212 and the return water plug end 211 are fixedly connected to one end of the two inlet and outlet pipes 153, and the other ends of the two inlet and outlet pipes 153 are fixedly connected to the water outlet pipe 30 and the return water pipe 40 one by one, forming a connected state of water outlet and return water. The handle 21 is inserted into the plug end 105, and the two inlet and outlet pipes 153 are simultaneously stored in the slot 1051 hidden in the plug end 105, which is the storage state of the flushing assembly 2.

[0057] Working principle of this utility model:

[0058] By pressing the button switch 127, the main unit 1 is turned on, and the positive and negative pressure air pumps 121 are started at the same time. The air outlets of the positive and negative pressure air pumps 121 are connected to the inside of the water storage tank 11 through the air flow regulating valve 122, and the air inlets of the positive and negative pressure air pumps 121 are connected to the waste water tank 13. Then, the positive and negative pressure air pumps 121 pump air and pressurize the water storage tank 11, so that the water flow for rinsing the nasal cavity reaches a certain pressure. At this time, the air flow regulating valve 122 can also be used to adjust the air flow size of the positive and negative pressure air pumps 121 to the water storage tank 11 to control the regulation of the flushing water pressure;

[0059] After the positive and negative pressure air pumps 121 are started, at the same time, the air inlet ends of the positive and negative pressure air pumps 121 perform air extraction in the wastewater tank 13 through the negative pressure hole. Then, a negative pressure effect is generated in the wastewater tank 13, and the return pipe 40 connected to the wastewater tank 13 is opened to inhale air from the outside, thereby generating a certain suction force. When the air pressure in the water storage tank 11 reaches a certain pressure, the silicone control valve 124 is deformed, and the straight opening or cross-shaped opening on the silicone control valve 124 is in an open state at this time, and the water in the water storage tank 11 flows from. The straight opening or the cross-shaped opening flows to the water outlet end on the silicone control valve 124. Since the water outlet end and the water outlet pipe 30 are quickly discharged outward, the water flows through the water outlet pipe in the water inlet and outlet pipe 153 and the water outlet of the water outlet plug end 212 on the handle 21, and finally the water flows into the left nasal cavity or the right nasal cavity of the human body. The sewage after flushing, due to the negative pressure effect of the wastewater tank 13 at this time, the suction force generated by the return pipe 40 drains the sewage and quickly introduces the sewage into the wastewater tank 13, thereby reducing the falling or dripping of sewage.

[0060] By providing a plug-in and detachable flushing component 2 or a handle 21 detachably connected to the base 26, an inlet and outlet water pipe 153 of a certain length is provided between the flushing component 2 or the handle 21 and the main unit 1. When flushing the nasal cavity, the flushing component 2 or the handle 21 can be pulled out to achieve the purpose of keeping the flushing component 2 or the handle 21 away from the main unit, thereby reducing the probability of the main unit being wetted by water, effectively extending the service life of the main unit, and making operation and use more convenient.
