Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1-4, the utility model relates to a sputum aspirator, which comprises a shell 1, wherein one end of the shell 1 is provided with an air blowing inlet 4, the shell 1 is provided with an air outlet 7, a rotating wheel inner cavity 3 is arranged inside the shell 1, the rotating wheel inner cavity 3 is simultaneously communicated with the air blowing inlet 4 and the air outlet 7, a rotating wheel 2 is arranged inside the rotating wheel inner cavity 3, blades 21 are uniformly distributed on the outer side of the rotating wheel 2, a deflector rod 5 extending into the rotating wheel inner cavity 3 is also arranged on the shell 1, an elastic element is connected between the deflector rod 5 and the shell 1, and the rotating wheel 2 is contacted with the deflector rod 5 and drives the deflector rod 5 to axially reciprocate when rotating.

In this embodiment, the user blows and inhales with mouth alignment air-intake port 4 when using, the air current can make runner 2 take place to rotate in the time of runner inner chamber 3, runner 2 just can make driving lever 5's reciprocating motion with 5 interact of driving lever, the condition that the card went up appears in the time of making runner 2 rotate, thereby make whole casing 1 produce the vibration, the vibration of air current also can take place the vibration with inspiratory air current, the vibration of air current also makes air flue depths inner wall cilia produce the vibration, make the sputum and other secretions that glue in the air flue not hard up, break away from the air flue surface, can take off the sputum discharging device after feeling that sputum and other secretions are not hard up and break away from, expectorate, the operation is repeated, and the sputum discharging effect is good.

In this embodiment, the elastic element is a spring sleeved outside the shift lever 5, the spring can enable the shift lever 5 to automatically return, and the end of the shift lever 5 is preferably spherical, so that the shift lever can axially move when contacting with the rotating wheel 2.

In embodiment 1, as shown in fig. 4, the shift lever 5 is inserted into the inner cavity 3 of the rotor along the radial direction of the rotor 2 and contacts with the blades 21 of the rotor 2 in sequence, in this embodiment, the blades 21 of the rotor 2 are used as the contact part with the shift lever 5, and the blades 21 are continuously contacted with the shift lever 5 by the rotation of the rotor 2, so that the rotation of the rotor 2 is blocked.

In embodiment 2, as shown in fig. 1 to 3, a plurality of grooves 22 are formed around the center in the middle of one axial side of the rotating wheel 2, the shift lever 5 is inserted into the inner cavity 3 of the rotating wheel along the axial direction of the rotating wheel 2, and the end of the shift lever is in contact with the grooves 22, so that the lower end of the shift lever 5 can be always located in the grooves 22 by the rotation of the rotating wheel 2, the grooves 22 can be arc grooves, and the shift lever 5 can continuously reciprocate to generate incarceration.
