Detailed Description

Embodiments of the technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.

It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

Referring to fig. 1 to 4, the portable oxygen generating cup provided in this embodiment includes: the reaction cup 1, filter cup 2 and bowl cover 3, filter cup 2 connect in the upper end of reaction cup 1 with detachable mode, and bowl cover 3 sets up the upper end at filter cup 2, and bowl cover 3 is equipped with gas vent 11, threaded connection between every two, all is equipped with sealing washer 7 between filter cup 2 and the reaction cup 1 and between bowl cover 3 and the filter cup 2.

The inner cavity of the reaction cup 1 is a reaction chamber 8, the inner cavity of the filter cup 2 is a humidifying chamber 9, the bottom of the filter cup 2 is provided with a first air hole, the first air hole is provided with a check valve which is communicated from the reaction chamber 8 to the humidifying chamber 9 in a one-way manner, and the outlet of the first air hole is also provided with a bubble thinning device 5.

When the oxygen generating device is used, the nasal oxygen pipe is connected to the outside of the exhaust port 11, the reaction reagent for generating oxygen is added into the reaction bin 8, water is added into the humidification bin 9, oxygen generated by the reaction can be discharged from the exhaust port 11 through the humidification bin 9, and water in the humidification bin 9 can be used for washing and humidifying the passing oxygen, so that the reaction reagent is removed and the humidity is increased. The check valve can prevent water in the humidifying bin 9 from flowing back into the reaction bin 8, so that the oxygen production efficiency is affected; the refining device is used for reducing oxygen bubbles and increasing contact area so as to strengthen the gas washing and humidifying effects.

The oxygen generating cup provided by the embodiment only needs to be added with the reaction reagent and the water for gas washing, does not need professional equipment, is convenient to operate, can reduce the volume of the oxygen generating cup, prolongs the oxygen generating time through adding the reagent, and is convenient to carry.

Specifically, the check valve is a duckbill valve 4 made of a silica gel material, and the duckbill valve 4 is arranged at the outlet end of the first air hole. The duckbill valve 4 is in a normally closed state and is positioned in the humidifying bin 9, the duckbill is arranged upwards, after the air pressure in the reaction bin 8 is increased, the duckbill valve 4 is outwards opened in oxygen, so that the duckbill valve enters the humidifying bin 9, after the reaction is finished, the air pressure in the reaction bin 8 is reduced, and the duckbill valve 4 is closed.

The first air hole is positioned on one side of the opening position of the duckbill valve 4. The duckbill valve 4 is typically comprised of two duckbills that are normally held together such that the duckbill valve 4 remains closed and the two duckbills are separated when the duckbill valve 4 is opened. The first air hole is positioned on one side of the opening position of the duckbill valve 4, so that the air punched out of the first air hole directly acts on one of the duckbill parts, and the duckbill valve 4 is conveniently opened.

The lower end of the filter bowl 2 is also provided with a buffer bin 6, and the buffer bin 6 is provided with a second air hole for communicating with a reaction bin 8. Because the aperture of the second air hole is smaller, when the oxygen making cup is poured, the second air hole of the buffer bin 6 can reduce the speed of the reagent in the reaction bin 8 entering the buffer bin 6, thereby avoiding the reaction solution from entering the humidifying bin 9, and when the oxygen making cup is placed again, the liquid entering the buffer bin can flow back downwards through the second air hole. The bottom of the buffer bin 6 is in an inverted cone shape, and the air hole is positioned at the cone top of the inverted cone shape. The reagent in the buffer bin 6 is convenient to flow back into the reaction bin 8.
