Nasal aspirator body and nasal aspirator

Abstract

The utility model discloses a nasal aspirator body and a nasal aspirator. The nasal aspirator body comprises a power supply; the positive pressure pump comprises a positive pressure pump air outlet, and the positive pressure pump is arranged in the machine body shell; the electromagnetic valve comprises an electromagnetic valve first connecting port, an electromagnetic valve second connecting port and an electromagnetic valve third connecting port; the control device is used for being electrically connected with the positive pressure pump and the electromagnetic valve. Due to the fact that the nasal aspirator comprises the positive pressure pump, when the nasal aspirator works, the air outlet of the positive pressure pump outputs air, the air sequentially passes through the third connector of the electromagnetic valve and the second connector of the electromagnetic valve and enters the air bag cavity, and when the air bag is expanded to the required degree, the air in the air bag sequentially passes through the second connector of the electromagnetic valve and the first connector of the electromagnetic valve and is rapidly exhausted; the air bag in the suction head of the nasal aspirator is rapidly contracted, so that negative pressure is rapidly generated in the containing cavity, and the action of sucking snot is rapidly completed. The inflated air bag instantly releases positive pressure to enable the containing cavity to generate negative pressure, the nasal aspirator body does not need to be provided with a negative pressure cavity independently, and the structure of the nasal aspirator is simplified.

[0044] Embodiment 2:

[0045] like Figures 1 to 6 As shown, the nasal aspirator provided in the embodiment of the present application includes a nasal aspirator suction head and a nasal aspirator body provided in the first embodiment. The nasal aspirator suction head is arranged on the nasal aspirator body. The nasal aspirator suction head includes a suction tip 100, a suction tip shell 200, an air bag body 300 and a suction tip bottom cover 400. The suction tip 100 is a probe structure for probing into the nasal cavity.

[0046] The suction end 100 is provided with a first channel 110. In one embodiment, the suction end 100 may also be provided with a one-way valve 120. When the airbag 300 is inflated, the one-way valve 120 is opened to exhaust air outwards, and when the snot is sucked, the one-way valve 120 is closed.

[0047] A cavity is disposed in the suction head housing 200 , and the suction head housing 200 includes a first opening 210 and a second opening 220 . The first opening 210 , the cavity and the second opening 220 are connected, and the suction tip 100 cooperates with the first opening 210 .

[0048] The airbag body 300 includes an airbag 310 and an airbag body installation portion 320. The airbag is provided with an airbag opening end, and the airbag body installation portion 320 is arranged at the airbag opening end.

[0049] The suction head bottom cover 400 is provided with a mounting seat 410 and a second channel 420. The mounting seat 410 cooperates with the second opening 220, and the airbag 310 can be fixed in the cavity through the airbag mounting portion 320. The airbag 310 fixed in the cavity can divide the cavity into a receiving cavity 230 and an airbag cavity 240. The receiving cavity is used to receive secretions produced by the nasal cavity, such as mucus.

[0050] The first channel 110 is in communication with the storage cavity 230 , one end of the second channel 420 is in communication with the airbag cavity 240 , and the other end of the second channel 420 is in communication with the airbag air inlet 510 .

[0051] In the nasal aspirator provided in the embodiment of the present application, the suction head bottom cover 400 and the body shell 500 can be provided separately or integrally formed. In one embodiment, the suction head bottom cover 400 and the body shell 500 are two independent components. In another embodiment, the suction head bottom cover 400 and the body shell 500 are integrally formed, and specifically, the suction head bottom cover 400 and the body front shell 520 can be integrally formed.

[0052] The nasal aspirator provided in the embodiment of the present application has the following working process: the positive pressure pump outlet 810 outputs gas, which passes through the third connection port 730 of the solenoid valve, the second connection port 720 of the solenoid valve and the air inlet 510 of the airbag in sequence, and finally enters the airbag cavity 240, so that the airbag 310 expands in a short time. When the airbag 310 expands to the required degree, the solenoid valve 700 starts to work, and the gas in the airbag 310 is quickly discharged through the second connection port 720 of the solenoid valve and the first connection port 710 of the solenoid valve in sequence. Since the first connection port 710 of the solenoid valve is connected to the atmosphere, the airbag 310 contracts rapidly, so that negative pressure is quickly generated in the storage cavity 230, and the snot is sucked in through the first channel 110 of the suction terminal 100 and stored in the storage cavity 230.

[0053] The nasal aspirator provided in the embodiment of the present application has no negative pressure chamber provided in the nasal aspirator body. The positive pressure pump outlet 810 outputs gas which directly passes through the third connection port 730 of the solenoid valve, the second connection port 720 of the solenoid valve and the air inlet 510 of the airbag in sequence, and finally enters the airbag cavity 240. The airbag 310 expands and then contracts, causing a negative pressure to be instantly generated in the storage cavity, and secretions such as nasal mucus are sucked into the storage cavity for storage. The present application directly inflates the airbag 310 through the positive pressure generated by the positive pressure pump 800, causing the airbag 310 to expand. The inflated airbag 310 instantly releases gas, directly causing a momentary large negative pressure to be generated in the storage cavity 230 to absorb the nasal mucus. There is no need to provide a transition negative pressure chamber in the nasal aspirator body, thereby simplifying the structure of the nasal aspirator.

[0054] The above contents are further detailed descriptions of the present application in combination with specific implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application.
