Technical Field

[0001] The utility model relates to the field of nasal aspirators, in particular to an air bag type nasal aspirator. Background Art

[0002] A nasal aspirator is a device used to suck out nasal secretions. It is usually used when infants and young children have a stuffy nose and cannot expel the secretions. The nasal aspirators currently on the market use an air pump inside the body to suck out the secretions, creating negative pressure to suck out the secretions. However, the secretions often enter the trachea inside the body, making it inconvenient for users to clean. Moreover, if users do not clean it in time, the secretions will dry and harden and clog the pipe.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0016] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0017] Please see attached Figure 1-2 The present application provides an airbag type nasal aspirator, which includes a body 1 and a nasal suction head 2 assembled on the outside of the body. A negative pressure mechanism 3, a battery and a solenoid valve 4 are provided in the body. The battery provides working power for the negative pressure mechanism and the solenoid valve. The negative pressure mechanism is specifically an air pump. The nasal suction head has a negative pressure chamber 5 and a suction chamber 6. An airbag body 7 is provided in the suction chamber. A suction area 8 is formed between the outside of the airbag body and the suction chamber. A suction end head 9 connected to the inside of the airbag body is provided on the nasal suction head. The negative pressure mechanism 3, the negative pressure chamber 5, the solenoid valve 4 and the suction area 8 are connected in sequence. During specific operation, the solenoid valve is in the closed state, and the negative pressure mechanism vacuums the negative pressure chamber. After a certain period of vacuuming, the solenoid valve opens. Since the negative pressure chamber is connected to the negative pressure area, a pressure difference is generated between the negative pressure area and the inside of the airbag, causing the airbag to expand and contract repeatedly, thereby completing multiple suction actions, and sucking the secretions in the user's nasal cavity into the airbag. Under the isolation effect of the airbag, the secretions cannot enter the body. After each use, the user can simply remove the airbag and clean it.

[0018] The negative pressure chamber 5 has a first interface and a second interface. The negative pressure mechanism 3 is connected to the first interface, and the second interface is connected to the solenoid valve 4, which can be connected specifically through an air pipe.

[0019] The body has a mounting base 12, the nasal suction head 2 is connected to the mounting base and encloses the negative pressure chamber 5, the mounting base is provided with a suction port 13, the nasal suction head is provided with an trachea 14 that is connected to the suction area and is used to dock with the suction port, the trachea 14 is arranged in the negative pressure chamber and is located on the axis of the negative pressure chamber, the suction port 13 is located in the middle position of the mounting base, and the suction port is provided with a sealing portion 15 at the position where it docks with the trachea, and the sealing portion can enhance the airtightness of the connection between the suction port and the trachea.

[0020] The outer peripheral wall of the mounting seat 12 is provided with a locking position 16, and the nose suction head is provided with a locking portion 17 that cooperates with the locking position. The nose suction head and the mounting seat are connected by a locking structure, which has the advantage of easy installation and disassembly.

[0021] In order to enhance the sealing performance between the mounting seat and the nose suction head, a sealing ring 18 is provided on the outer peripheral wall of the mounting seat, and the sealing ring is used to seal the connection between the mounting seat and the nose suction head.

[0022] The nasal suction head is provided with an annular step 19 on the edge of the suction chamber, and the airbag body 7 has a hanging lining 71 mounted on the annular step. The suction end head 9 is clamped on the edge of the suction chamber and presses the hanging lining. After the user removes the suction end head, the airbag body can be directly taken out for cleaning. It is also very convenient to install. It only needs to be hung on the annular step, and then the hanging lining is pressed tightly by connecting the suction end head and the nasal suction head, which can also enhance the air tightness of the connection between the nasal suction head and the suction end head.

[0023] The end of the airbag 7 facing the nasal suction tip is concave to form a storage cavity, and the inhaled secretions are stored in the storage cavity. The side wall of the airbag is provided with multiple structural protrusions 72 protruding toward the storage cavity. The multiple structural protrusions are evenly distributed circumferentially. The provision of the structural protrusions can accelerate the rebound speed of the airbag to improve the efficiency of suctioning secretions.
