Detailed Description

In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.

See fig. 1-8;

the invention provides an atomization device for improving the utilization rate of liquid medicine, which comprises:

a bite body 1, one end of the bite body 1 is formed as a bite holding part 101, and the other end is formed as a bite body connecting part 102;

the corrugated pipe 3 is communicated with the bite nozzle body 1 through a three-way joint 4, and the corrugated pipe 3 and the bite nozzle body 1 are respectively arranged on two straight pipe joints of the three-way joint 4; and

the medicine cup 2 is connected with the vertical pipe joint 403 of the three-way joint 4;

a flow stopping structure 5 is formed at the joint of the bite-bit body 1 and the three-way joint 4, and the flow stopping structure 5 is used for preventing saliva from entering the three-way joint 4 during expiration;

a condensation reflux structure 6 is formed at the joint of the corrugated pipe 3 and the three-way joint 4;

when the patient exhales, part of the liquid medicine is guided into the three-way joint 4 through the condensation backflow structure 6 and flows back into the medicine cup 2 through the pressure of breathing.

The embodiment specifically discloses an atomization device with a novel structure, which comprises a mouthpiece body 1 for a user to bite and a medicine cup 2 for containing medicine liquid, wherein the medicine cup 2 has a pressure nozzle inside the same structure as the atomizer in the prior art, and is filled with the medicine liquid to be atomized, and through connection with an external air supply device or an oxygen supply device, the user can atomize the medicine liquid once inhaling by using the mouthpiece body 1 and directly act along with air flow. Meanwhile, the difference from the atomizer in the prior art is that the three-way joint 4 is connected with the corrugated tube 3 in the present embodiment, meanwhile, a flow stopping structure 5 is formed at the connection position of the mouthpiece body 1 and the three-way joint 4, the flow stopping structure 5 can prevent part of saliva from entering the three-way joint 4 along with the exhalation, and simultaneously can not prevent part of the liquid medicine from returning to the three-way joint 4 or the corrugated tube 3 along with the exhalation, and secondly, the connection position of the corrugated tube 3 and the three-way joint 4 in the present embodiment has the condensation backflow structure 6, which can condense part of the liquid medicine returning along with the exhalation on the inner wall of the condensation backflow structure 6, and under the pressure action of next inhalation, the condensed liquid medicine is driven to flow back to the three-way joint 4 again and finally enter the medicine cup 2 for next atomization. By the mode, partial water can be prevented from entering the three-way joint 4/the medicine cup 2, the pollution of the liquid medicine is reduced, the exhaled liquid medicine can be partially recycled, the waste of the liquid medicine is reduced, and the atomization treatment cost is reduced to a certain degree.

It should be noted that: the flow stopping structure 5 in the embodiment is only used for preventing part of the saliva from entering the three-way joint 4, and the inflow of the saliva cannot be absolutely prevented, but the partial prevention is a great innovation of the atomizer, so that the pollution of the liquid medicine can be reduced; in the same way, the condensation reflux structure 6 can partially recycle the liquid medicine, and can not recycle the whole liquid medicine temporarily, but even if the condensation reflux structure is used, a great part of liquid medicine can be still saved, the cost of the atomization treatment is reduced, and the condensation reflux structure belongs to a technical breakthrough of the atomization treatment.

Preferably, in the present embodiment, the bite holding part 101 of the bite body 1 and the bite body connecting part 102 are in a communicated hollow structure, and the cross-sectional dimension of the bite holding part 101 is smaller than that of the bite body connecting part 102;

In addition, the first straight pipe joint 401 is partially embedded into the mouth piece connecting part 102, so that groove structures with different sizes are formed between the embedded part and the mouth piece connecting part 102, and when the mouth piece 1 passes through the three-way joint 4 during the flow path of the mouth water, part of the mouth water is blocked on the inner wall of the mouth piece connecting part 102 and the formed groove during the expiration through the large-size mouth piece 1 and then through the small-size first straight pipe joint 401, so that the flow stopping structure 5 is formed; the liquid medicine flow path enters the three-way joint 4 through the medicine cup 2 and then enters the mouthpiece body 1 through the first straight pipe joint 401, so that the liquid medicine flow path is from the small-sized first straight pipe joint 401 to the large-sized mouthpiece body connecting part 102, the flow path does not reduce the flow of the atomized liquid medicine due to the existence of the aperture difference, and meanwhile, the aperture difference of the embodiment can deepen the respiratory resistance and drive the patient to breathe forcefully, so that the effect of the atomization treatment is further improved.

Meanwhile, the bite nozzle body 1 can be designed into a bent rotary structure to increase the curvature of a water circulation path by only one structural form of the stop flow structure 5; or a flow guide plate structure which is inclined towards the biting part 101 of the biting body 1 is designed at the joint of the biting body 1 and the three-way joint 4, and the flow guide plate structure is similar to the principle of the hole diameter difference structure. And the various flow stopping structures 5 can prevent partial water from invading and stop the partial water at the position of the mouthpiece body, thereby reducing the pollution of the liquid medicine.

In order not to hinder the breathing, a plurality of openings 603 are formed in the conical cylinder section 602, the openings 603 are in the form of oblong holes and are uniformly distributed along the circumferential direction of the conical cylinder section 602, and meanwhile, the openings can extend along the axis of the conical cylinder section 602, so that the size of the openings can be increased. As the breath goes, part of the liquid medicine adheres to the condensation and return structure 6, and as the pressure of inspiration is increased, the part of the liquid medicine flows back into the three-way joint 4 under the action of the pressure and reenters the medicine cup 2 through the vertical pipe joint 403 of the three-way joint 4 to be atomized for the next time.

In a similar way, the condensation reflux structure 6 is only one structural form, and the flow guide plate with a necking structure can also be adopted, so that the breathing process is not influenced, part of liquid medicine can be prevented from being exhaled, and the treatment cost is saved.

The medicine cup 2 in the embodiment comprises a cup body and a cup cover;
