Description

Technical Field

[0001] The utility model relates to the technical field of nasal aspirators, and particularly relates to a novel nasal aspirator. Background Art

[0002] During a child's cold, especially for children aged 1 to 3 years old, it is difficult for them to independently expel the liquid secretions in the nasal cavity, and it is also difficult to independently remove the solid secretions in the nasal cavity. This can easily lead to unsmooth breathing, thus affecting the child's respiration. In severe cases, it may even cause phenomena such as nasal cavity ulceration and blocked nostrils. The continuously secreted nasal mucus may flow back into the lungs due to blocked nostrils, leading to diseases such as pneumonia. Therefore, a nasal aspirator is needed to clean the nasal cavity. For example, the patent application number is JP2023009086D, and the publication date is January 10, 2024. It discloses a nasal aspirator with the ability to suck out nasal mucus, which includes a nasal bottle, a tube, and a pump. The nasal bottle is a part that is placed close to the nostrils without inserting into the human nasal cavity. The nasal bottle has a generally cylindrical shape, with a dome-shaped part whose diameter gradually increases from the front end in contact with the nostrils to the central part and a cylindrical part extending from the central part to the base end. The tube is flexible and connects the nasal bottle and the pump. The pump includes a cylinder body, a pump cover, and a piston. The cylinder body is a bottomed cylinder with an open top, having an air inlet hole that communicates with the inside and is connected to the tube, and an exhaust hole that communicates with the outside of the cylinder body. The pump cover has a portable handle, which has a disc-shaped cover body that closes the opening of the pump body, two struts that stand upright from two points on the periphery of the cover body, and a crossbeam connecting the struts. The piston is composed of a disc-shaped piston head placed in the hollow cylindrical space formed by the cylinder body and the cover body and a substantially T-shaped piston head installed at the center of the piston head and exposed outside through the piston head. The pump cover is equipped with a special-shaped connecting rod. The connecting rod extends between the struts of the portable handle and has a gently curved, substantially straight curved part and an annular part formed at the center of the curved part. The curved part and the annular part are exposed to the outside through the pump cover.

[0003] However, the tube body in the above-mentioned literature is connected to the front cavity of the nasal bottle, and the suction port at the front of the nasal bottle is horizontally arranged. As a result, the sucked nasal mucus enters the rear end of the nasal bottle and then enters the tube body from the rear end, resulting in poor adsorption reliability. In addition, since the front end of the nasal bottle is horizontally arranged, when sucking nasal mucus, it is easy to cause the nasal mucus in the nasal bottle to flow backward. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a novel nasal aspirator that can better prevent backflow and has a simple and reliable structure.

[0005] To achieve the above object, a new type of nasal aspirator includes a suction device, a connecting tube, and a nasal suction body. The suction device is connected and communicated with the nasal suction body through the connecting tube. The nasal suction body includes a housing body and a nasal suction head. One side of the housing body is provided with an opening, and the connecting tube is connected to the housing body through the opening to form an integral body. The nasal suction head is detachably connected to the housing body to form a first cavity. A second cavity is formed inside the nasal suction head. The second cavity is communicated with the first cavity and the opening. The other end of the nasal suction head is provided with an extension part and a nasal suction opening. A third cavity is provided inside the extension part. The third cavity is communicated with the nasal suction opening and the first cavity. The nasal suction opening is inclined at the end of the extension part, and the axis of the nasal suction opening forms an angle with the axis where the first cavity is located.

[0006] With the above settings, by providing an opening on one side of the housing body, it is convenient for the connecting tube to be connected to the housing body through the opening to form an integral body; by providing the nasal suction opening at the other end of the nasal suction head inclined at the end of the extension part and the axis where the nasal suction opening is located forms an angle with the axis where the first cavity is located. In this way, during the process of sucking nasal mucus, when the outer side of the inclined nasal suction head is placed outward, the inclined nasal suction opening can better adhere to the inner wall of the nasal cavity, thereby better sucking the nasal mucus in the nasal cavity, and also preventing the situation of the sucked nasal mucus from flowing back; in addition, a third cavity is provided inside the extension part, so that the third cavity is communicated with the nasal suction opening. Then, by pumping air through the suction device, the nasal mucus is sucked from the nasal suction opening through the second cavity and the third cavity into the first cavity, thereby realizing the extraction of nasal mucus, and at the same time preventing the nasal mucus from flowing back to the nasal suction opening. The structure is simple.

[0007] Furthermore, one end of the nasal suction head is provided with a first boss, and a second boss is provided on one side of the first boss. The nasal suction head is embedded in the housing body through the first boss, and a first cavity is formed between the second boss and the housing body. A second cavity is provided inside the second boss.

[0008] With the above settings, by providing a first boss at one end of the nasal suction head and a second boss on one side of the first boss, the nasal suction head can be embedded in the housing body through the first boss, and then a first cavity is formed between the second boss and the housing body; in addition, by providing a second cavity inside the second boss, the first cavity and the second cavity can be communicated; the structure is simple and convenient for disassembly and cleaning.

[0009] Furthermore, the diameter of the first cavity is larger than the diameter of the second boss.

[0010] With the above settings, after the nasal suction head is embedded in the housing body through the first boss, a first cavity can be formed between the outer side of the second boss and the inner side of the housing body, and the first cavity is communicated with the second cavity.

[0011] Further, the diameter of the first boss is greater than that of the second boss. The diameter of the first boss matches the diameter of the first cavity. A first step is provided on the first boss, and the first step is arranged in contact with the inner side of the housing.

[0012] With the above arrangement, it is convenient for the first boss to be in contact with the inner side of the housing through the first step, and it can just be embedded into the housing, while making the second boss completely placed in the first cavity of the housing.

[0013] Further, the opening communicates with the first cavity, and one end of the connecting pipe is connected to the opening.

[0014] With the above arrangement, the first cavity can communicate with the connecting pipe through the opening.

[0015] Further, the middle part of the third cavity bulges towards both sides to form an arc part and gradually narrows at both ends. One end of the third cavity communicates with the other end of the second cavity, and the other end of the third cavity communicates with the nasal suction port.

[0016] With the above arrangement, the second cavity, the third cavity and the nasal suction port are interconnected. At the same time, by setting the middle part of the third cavity to bulge towards both sides to form an arc part and gradually narrow at both ends, when the suction device presses air into the first cavity through the connecting pipe, part of the nasal mucus attached to the inner wall of the second cavity flows into the arc part bulging in the middle of the third cavity under the action of the pressed air, avoiding the nasal mucus flowing directly to the nasal suction port and causing blockage.

[0017] Further, the extension part is arranged to incline downward, with an included angle of 20° - 60°. The other outer side of the nasal suction port coincides with one outer side of the extension part.

[0018] With the above arrangement, during the process of sucking nasal mucus, when the inclined side of the nasal suction head is placed outward, the inclined nasal suction port can better adhere to the inner wall of the nasal cavity, and thus better suck the nasal mucus in the nasal cavity.

[0019] Further, the other end of the connecting pipe is connected to the bottom of the suction device. A straight cylinder is provided at the bottom of the suction device. The inside of the suction device communicates with the outside through the straight cylinder, and a sealing sleeve is sleeved on the straight cylinder.

[0020] With the above arrangement, when the suction device presses air into the connecting pipe, the sealing sleeve is removed to make the inside of the suction device communicate with the outside atmospheric pressure. During the process of pressing air, the air inside the suction device will be discharged to the outside through the straight cylinder, reducing the air pressure into the connecting pipe.

[0021] Further, the distance from one end of the second cavity to the first boss is greater than the distance from the opening to the first boss.

[0022] The above settings prevent the nasal mucus in the first cavity connected to the opening from flowing back into the second cavity and then flowing to the nasal suction port after nasal mucus is aspirated. Description of the Drawings

[0024] Figure 2 is Figure 1 A cross-sectional view taken along line A-A in Detailed Description of the Invention

[0025] The embodiments of the present invention will be further described in detail below in conjunction with the drawings and the detailed description of the invention.

[0026] As Figure 1-2 shown, the present invention provides a new type of nasal aspirator, which includes a suction device 1, a connecting pipe 2 and a nasal suction body 3. The suction device 1 is connected and communicated with the nasal suction body 3 through the connecting pipe 2. The nasal suction body 3 includes an outer shell 31 and a nasal suction head. One side of the outer shell 31 is provided with an opening 311. One end of the connecting pipe 2 is connected to the opening 311. The connecting pipe 2 is integrally connected to the outer shell 31 through the opening 311. One end of the nasal suction head is provided with a first boss 21. One side of the first boss 21 is provided with a second boss 22. The first boss 21 is provided with a first step 211. The first step 211 is arranged in contact with the inner side of the outer shell 31. It is convenient for the first boss 21 to be in contact with the inner side of the outer shell 31 through the first step 211, and it can just be embedded into the outer shell 31. At the same time, the second boss 22 is completely placed inside the outer shell 31. A first cavity 41 is formed between the outer side of the second boss 22 and the inner side of the outer shell 31. The opening 311 is communicated with the first cavity 41. The second cavity 42 is arranged inside the second boss 22. One end of the first cavity 41 is communicated with the second cavity 42. In this embodiment, the diameter of the outermost side of the first boss 21 is greater than the diameter of the outermost side of the second boss 22. The diameter of the cross-section of the first cavity 41 is greater than the diameter of the outermost side of the second boss 22. The diameter of the outermost side of the first boss 21 matches the diameter of the cross-section of the first cavity 41.

[0027] As Figure 2As shown, the other end of the nasal aspirator head is provided with an extension part 23 and a nasal aspiration opening 24. The extension part 23 is arranged to slope downwards. A third cavity 43 is arranged inside the extension part 23. The middle part of the third cavity 43 bulges towards both sides to form an arc part 433 and both ends gradually narrow down. One end of the third cavity 43 is communicated with the other end of the second cavity 42, and the other end of the third cavity 43 is communicated with the nasal aspiration opening 24, enabling the first cavity 41, the second cavity 42, the third cavity 43 and the nasal aspiration opening 24 to be communicated with each other. At the same time, by arranging the middle part of the third cavity 43 to bulge towards both sides to form the arc part 433 and both ends to be gradually narrowed down, when the suction device 1 applies air pressure to the first cavity 41 through the connecting pipe 2, part of the nasal mucus adhering to the inner wall of the second cavity 42 flows into the arc part 433 bulging in the middle of the third cavity 43 under the action of the air pressure, avoiding the nasal mucus flowing directly to the nasal aspiration opening 24 and causing blockage. The nasal aspiration opening 24 is obliquely arranged at the end of the extension part 23, and the axis a where the nasal aspiration opening 24 is located intersects with the axis b where the second cavity 42 is located.

[0028] In this embodiment, the included angle c between the axis a where the nasal aspiration opening is located and the axis b where the second cavity 42 is located is 24°. One outer side surface 241 of the nasal aspiration opening is obliquely arranged with respect to the outer side surface 231 of the extension part. The other outer side surface 242 of the nasal aspiration opening coincides with the outer side surface 232 of the extension part. In this way, during the process of aspirating nasal mucus, when the inclined side of the nasal aspirator head is placed outwards, the obliquely arranged nasal aspiration opening 24 can better adhere to the inner wall of the nasal cavity, and thus better aspirate the nasal mucus in the nasal cavity.

[0029] As Figure 2 shown, in this embodiment, the distance from one end of the second cavity 42 to the first boss 21 is greater than the distance from the opening 311 to the first boss 21, thus avoiding the nasal mucus in the first cavity 41 communicated with the opening 311 flowing back into the second cavity 42 and then flowing to the nasal aspiration opening 24 after aspirating nasal mucus; The suction device 1 is a prior art and has been specifically disclosed in the document with the patent application number TW113200192, and will not be elaborated here.

[0030] The working principle of the present utility model: By providing an opening on one side of the outer shell, it is convenient for the connecting pipe to be connected to the outer shell through the opening to form an integral body; by providing a nasal suction opening at the other end of the nasal suction head, the nasal suction opening is inclined at the end of the extension part and the axis where the nasal suction opening is located forms an angle with the axis where the first cavity is located. In this way, during the process of sucking nasal mucus, when the outer side of the inclined nasal suction head is placed outward, it can make the inclined nasal suction opening better adhere to the inner wall of the nasal cavity, thereby better sucking the nasal mucus in the nasal cavity, and also preventing the situation of the sucked nasal mucus from flowing back; in addition, a third cavity is provided in the extension part, so that the third cavity is communicated with the nasal suction opening, and then through the suction device to pump air, the nasal mucus is pumped from the nasal suction opening through the second cavity and the third cavity into the first cavity, thereby realizing the extraction of nasal mucus, and at the same time preventing the nasal mucus from flowing back to the nasal suction opening, with a simple structure.
