Referring to fig. 1, a nasal aspirator comprising: a housing 100, a suction device 600, a suction head 200 and; the suction device 600 is disposed within the housing 100; the suction head 200 is connected to the housing 100, a first chamber 350 and a second chamber 500 are provided between the suction head 200 and the housing 100, and the suction head 200 is connected to the suction device 600 through the first chamber 350 and the second chamber 500 in sequence; a molding member 300 is provided between and connected to the suction head 200 and the suction device 600, and the first chamber 350 and the second chamber 500 are both provided to the molding member 300; the molding member 300 is provided with a connection passage 900, and the first chamber 350 and the second chamber 500 are communicated through the connection passage 900. After the suction device 600 is started, air is adsorbed, so that the air in the first chamber 350 and the second chamber 500 moves towards the suction device 600, and negative pressure adsorption force is generated at the suction head 200, so that nasal fluid can be sucked through the suction head 200. After the nasal fluid is sucked from the suction head 200, it will move into the first chamber 350. The molding 300 can mold the first chamber 350 and the second chamber 500 directly between the tip 200 and the housing 100, so that the first chamber 350 and the second chamber 500 for storing nasal fluid can be simply and directly formed between the housing 100 and the tip 200. In addition, the first chamber 350 and the second chamber 500 can be easily disassembled and assembled by disassembling and assembling the molding member 300, so that convenience can be provided for cleaning nasal liquid in the first chamber 350 or the second chamber 500, and the assembly is simple and convenient.

In certain embodiments, referring to fig. 2, a suction channel 230 is provided within the suction head 200, the suction channel 230 being in communication with the first chamber 350, the first chamber 350 being in communication with the second chamber 500 via a connecting channel 900, the second chamber 500 being in communication with the outlet conduit of the suction device 600. Upon activation of the suction device 600, nasal fluid will be absorbed through the second chamber 500, the connecting channel 900, the first chamber 350 and the suction channel 230.

In certain embodiments, referring to fig. 3, the connecting channel 900 communicates with the tops of the first chamber 350 and the second chamber 500. After the nasal fluid is sucked into the first chamber 350, it will be stored at the bottom of the first chamber 350 under the influence of its own weight. The connection channel 900 at the top of the first chamber 350 is directly spatially separated from the bottom of the first chamber 350, so that the nasal fluid is not easy to directly move from the connection channel 900 to the second chamber 500 before the nasal fluid in the first chamber 350 overflows, thereby ensuring that the suction device 600 is not easily disturbed or damaged by the nasal fluid.

Specifically, the first chamber 350 is disposed in the middle of the molding member 300, and the second chamber 500 is disposed at the outer periphery of the molding member 300 and surrounds the first chamber 350. Of course, the first chamber 350 and the second chamber 500 may also be disposed side by side, and the specific embodiment may be adjusted accordingly according to actual needs, which is not limited herein.

In some embodiments, referring to FIG. 3, one of the molding 300 and the cleaner head 200 is provided with a positioning boss 330, and the other is provided with a positioning groove 270, and the positioning boss 330 is snapped into the positioning groove 270. The positioning boss 330 and the positioning groove 270 can provide relative positioning for the molding 300 and the suction head 200 when they are assembled, thereby ensuring that they can be assembled smoothly and stably and reducing the difficulty of assembly therebetween.

Specifically, the positioning boss 330 is annular and is disposed at the top of the molding 300, and the positioning groove 270 is annular and is disposed at the bottom of the suction head 200. Of course, the positioning boss 330 may be disposed at the bottom of the suction head 200, and the positioning groove 270 may be disposed at the top of the molding member 300, which may be adjusted according to practical needs, and is not limited herein.

In some embodiments, referring to fig. 3, the positioning boss 330 is disposed on the molding member 300, the positioning groove 270 is disposed on the suction head 200, and the positioning boss 330 and the positioning groove 270 are both annular; the connection channel 900 comprises a first channel 335 arranged on the positioning boss 330, the suction head 200 is provided with a second channel 250, the first channel 335 can be communicated with the second channel 250, and the first chamber 350, the first channel 335, the second channel 250 and the second chamber 500 are sequentially communicated. The first channel 335 and the second channel 250 are capable of connecting the first chamber 350 and the second chamber 500, respectively, thereby ensuring that the suction device 600 is capable of generating suction forces at the first chamber 350 and the suction head 200 by means of air. Because the positioning boss 330 and the positioning groove 270 are both annular, the positioning boss 330 can relatively rotate relative to the positioning groove 270, so that the first channel 335 and the second channel 250 can be communicated or isolated in the process of relatively rotating the first channel and the second channel, further, the opening and closing control effect on the suction force of the nasal liquid can be simply and effectively achieved, and the communication between the first chamber 350 and the second chamber 500 can be timely blocked, so that the nasal liquid can be prevented from flowing to the suction device 600 and causing interference and damage to the suction device.

In some embodiments, referring to fig. 4, the molding 300 is provided with a passage hole 370, and both ends of the passage hole 370 are respectively communicated with the second chamber 500 and the second channel 250. The passage hole 370 may communicate the second chamber 500 with the second passage 250, and enable the suction force generated by the suction device 600 through the air to be smoothly transferred from the second chamber 500 to the first chamber 350, thereby ensuring that the nasal fluid can be smoothly sucked into the first chamber 350. Since the first chamber 350, the second chamber 500, the first passage 335 and the passage hole 370 are all directly formed on the molding member 300, various structures can be simply and directly molded by installing the molding member 300, and there are advantages in that material costs are saved and assembly is simplified.

Specifically, both ends of the second passage 250 communicate with the passage hole 370 and the first passage 335, respectively.

In some embodiments, referring to fig. 3, a connection member 400 is provided between the housing 100 and the molding member 300, and the second chamber 500 includes a first inner cavity 390 provided in the molding member 300 and a second inner cavity 470 provided in the connection member 400, and the connection passage 900, the first inner cavity 390, and the second inner cavity 470 are sequentially communicated. The first inner cavity 390 can transfer nasal liquid into the second inner cavity 470, and the second chamber 500 is divided by the connecting piece 400, so that the second chamber 500 can be directly and effectively exposed when the forming piece 300 and the connecting piece 400 are mutually separated, thereby being convenient for cleaning the second chamber 500, and further providing convenience for the whole cleaning process of the nose aspirator.

Specifically, the molding member 300 and the connecting member 400 are screw-coupled. The screw connection not only can firmly connect the two, but also has the advantage of easy disassembly and assembly, thus facilitating separation of the two and facilitating the cleaning process of the second chamber 500.

In certain embodiments, referring to fig. 5, the bottom wall of the second lumen 470 is provided with an inner boss 410, and a vent channel 430 is provided within the inner boss 410, the vent channel 430 communicating with the second lumen 470 from the top of the inner boss 410, the vent channel 430 passing through the bottom wall of the second lumen 470 and being connected to the suction device 600. After the adsorption device is activated, the air flow will enter the suction device 600 from the top of the inner boss 410 through the air passage 430. Thus, only a small amount of nasal fluid will remain in the second lumen 470 under the influence of its own weight at the bottom of the second lumen 470. Because the air flow and the suction force attached to the air flow do not directly contact the nasal fluid at the bottom of the second cavity 470, the nasal fluid is effectively prevented from being sucked into the ventilation channel 430, and thus the suction device 600 is prevented from being interfered by the nasal fluid.

In some embodiments, referring to fig. 5, a crossing 450 is provided on a sidewall of the top of the inner boss 410, the crossing 450 communicating the vent passage 430 with the second lumen 470. The passage opening 450 is formed on the side wall of the inner boss 410, so that the nasal liquid will contact with the end surface of the inner boss 410 under the action of self weight in the falling process, and is difficult to directly enter the passage opening 450 located at the side of the inner boss 410, thereby effectively reducing the amount of the nasal liquid flowing to the adsorption device and avoiding the interference or damage of the nasal liquid to the suction device 600.

Specifically, the top of the inner boss 410 is provided with a shielding cover 490, the shielding cover 490 sealing off the ventilation channel 430, and the side of the shielding cover 490 and extending outwards relative to the crossing 450.

In certain embodiments, referring to fig. 2, suction device 600 includes a water-air pump, an air inlet channel 650, and an air outlet channel 630, with air inlet channel 650 communicating with air outlet channel 630 via the water-air pump; the outlet channel 630 communicates to the outside of the housing 100, and the inlet channel 650 communicates with the second chamber 500. After the water vapor pump is started, air is driven to enter the water vapor pump from the air inlet channel 650 and is discharged from the air outlet channel 630. Thus, a negative pressure effect is generated on the second chamber 500 through the air inlet channel 650, and the air in the suction head 200, the first chamber 350 and the second chamber 500 moves towards the air inlet channel 650, so that the purpose of sucking the nasal liquid at the suction head 200 into the first chamber 350 is directly and effectively achieved.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
