The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art in a specific case.
Referring to fig. 1 to 5, a spray chamber of a nasal irrigator according to an embodiment of the present utility model includes a spray head 100, a liquid storage chamber 200, and a bottom cover 300 sequentially disposed from top to bottom;
the liquid storage bin 200 is provided with an air passage 210, the air passage is communicated with the spray head 100 and an air inlet 310 on the bottom cover 300 to form an air outlet channel of the spray head 100, compressed air enters from the air inlet 310 of the bottom cover 300, passes through the air passage 210 and is finally discharged from the air outlet 110 of the spray head 100;
the liquid outlet 220 of the liquid storage bin 200 is close to the air outlet hole 110 of the spray head 100, and when the air outlet hole 110 of the spray head 100 exhausts outwards, negative pressure is generated in the liquid storage bin 200; because the air outlet hole 110 is close to the liquid outlet 220, the high-speed air flow of the air outlet hole 110 can generate a low-pressure area (Bernoulli principle) at the liquid outlet 220, the internal and external air pressures of the liquid storage bin 200 are unbalanced, and the physiological saline in the liquid storage bin 200 can flow out from the liquid outlet 220 under the action of the air pressure, and after the physiological saline flows out, the physiological saline can be blown off by compressed air to form a mist.
The spray bin of the nasal irrigator adopts the design of the spray head, the liquid storage bin and the bottom cover, and utilizes the air passage and the air outlet to blow air outwards, and utilizes the negative pressure principle to suck out the physiological saline from the liquid outlet of the liquid storage bin, so that the high-speed air flow atomizes the physiological saline to moisten the nasal cavity.
The reservoir 200 further comprises an air inlet 230, wherein the air inlet 230 allows air to enter the reservoir 200 for balancing the pressure difference between the interior of the reservoir 200 and the atmosphere; because the flow rate of the compressed gas ejected from the gas outlet 110 is constant (in the same gear), the negative pressure generated at the liquid outlet 220 is also relatively constant, and the water outlet speed of the liquid outlet 220 is constant under the condition that the air pressure inside the liquid storage bin 200 is balanced.
Further, the spray head 100 covers the outside of the liquid outlet. As will be appreciated from the drawing, the liquid outlet 220 is located near the air outlet 110 on the inner side of the nozzle 100, and compressed air flows around the liquid outlet 220 and then is ejected from the air outlet 110.
Further, the nozzle 100 is tapered, the air outlet 110 is located at the tip of the taper, the shape of the liquid outlet 220 of the liquid storage bin 200 is adapted to the shape of the nozzle 100, the liquid discharging direction of the liquid outlet 220 is the same as the direction of the air outlet 110, and the taper nozzle 100 has a certain pressurizing effect, so that the flow velocity of the compressed air is faster, and the liquid outlet 220 arranged in the same direction does not have a phenomenon of air flow backflow.
Furthermore, the supporting rib 120 is disposed at the inner side of the nozzle 100 near the air outlet 110, and since the nozzle 100 is inserted into the nasal cavity, a soft plastic is needed to make the component for improving comfort, so that a certain deformation occurs when the component is inserted into the nasal cavity, and since the air outlet 110 is very close to the liquid outlet 220, interference between the two components is avoided.
Further, the liquid storage bin 200 further comprises a liquid outlet channel 240, and a liquid inlet 241 of the liquid outlet channel 240 is close to the bottom of the liquid storage bin 200; according to the above, negative pressure is generated at the liquid outlet 220 of the liquid storage bin 200, and the physiological saline is pressed into the liquid outlet channel 240 from the liquid inlet 241 by the pressure inside the liquid storage bin 200, and finally flows out from the liquid outlet 220.
The liquid outlet channel 240 extends out of the liquid storage bin 200, and the end of the part of the liquid outlet channel extending out of the liquid storage bin 200 is a liquid outlet 220. As will be appreciated in connection with the drawings, the function of the extension is to allow the outlet 220 to be closer to the outlet aperture 110 in order to accommodate the shape of the spray head 100, while also allowing a cavity to be formed between the spray head 100 and the reservoir 200 to provide sufficient space for the compressed air.
Further, a liquid blocking member 320 is disposed between the air inlet 310 and the air channel 210 on the bottom cover 300, and the liquid blocking member 320 is loosened when the pressure inside the liquid storage compartment 220 is low, so that air can enter the liquid storage compartment 220. It can be understood that the contact positions of the air inlet hole 310, the air channel 210 and the liquid blocking member 320 are the air inlet portion 230, and the liquid blocking member 320 is a core member for specifically implementing the liquid blocking and ventilation function, and specifically, the liquid blocking member 320 may be a one-way valve, and preferably, the liquid blocking member 320 is a silicone sleeve. To explain further, referring to the drawings, the air inlet 310 is provided with an air channel matching portion 311, the liquid blocking member 320 is a silicone sleeve, and is sleeved at the end of the air channel 210, the end of the air channel 210 is matched with the liquid blocking member 320 at the air channel matching portion 311, specifically, the air channel matching portion 311 is a circular protrusion, the air channel 210 and the silicone sleeve sleeved on the air channel matching portion are inserted into the circular protrusion, wherein the matching between the silicone sleeve and the air channel matching portion 311 is loose, similar to the clearance fit, because of the soft characteristic of the silicone, the silicone is generally attached to the side wall of the air channel matching portion 311, so that the silicone sleeve is watertight, when the air pressure in the liquid storage bin 200 is reduced, under the action of the air, the air extrudes the silicone sleeve, so that a gap is generated between the silicone sleeve and the air channel matching portion 311, and thus the liquid storage bin 200 is formed.
Still further, one end of the liquid storage bin 200 is open, the edge of the bottom cover 300 is matched with the open edge of the liquid storage bin 200, and the liquid storage bin 200 is arranged in an open mode in consideration of the mold opening and stripping of injection molding, so that the processing cost can be reduced, and meanwhile, the open mode is convenient for cleaning the inside of the liquid storage bin 200.
Further, the bottom cover 300 is provided with a filling opening 330 and a filling opening cover 340.
The nose washing device comprises the nose washing device spray bin in any one of the above, and specifically comprises a main body 400 and a spray bin arranged on the main body 400, wherein the main body 400 is a hand-held air pump, and an air inlet hole 310 of the spray bin is connected to the output end of the air pump.
The present utility model is not limited to the above-mentioned embodiments, but is intended to be limited to the following embodiments, and any modifications, equivalent changes and variations in the above-mentioned embodiments can be made by those skilled in the art without departing from the scope of the present utility model.
