The flow path of oxygen is longer in this embodiment compared to the previous embodiment, so oxygen can have more temperature rise time, and since the inlet 183 is at the upper portion of the filter chamber 18, impurities naturally settled in the settling space 187 do not pass through the inlet 183 and enter the gasification assembly 17 again. To further increase the flow path of oxygen, the air tube 185 may be provided in a spiral structure to maximize the flow path of oxygen in a limited space.
To facilitate the heat exchange and warming of the oxygen as it passes through the gas filter layer 186, the gas filter layer 186 in this embodiment is made of a high thermal conductivity material, such as copper or a high thermal conductivity ceramic. The gas filtering layer 186 may be formed of a copper plate or a ceramic plate provided with a plurality of holes stacked one on top of the other.
To facilitate heat transfer, the periphery of the gas filtering layer 186 in this embodiment is closely attached to the inner wall of the filter cavity 18, the filter cavity 18 is made of a material with high thermal conductivity, and the material of the filter cavity 18 may be a cylinder or a ceramic with high thermal conductivity.
In order to enable the liquid oxygen to be gasified sufficiently in the gasification module 17, the gasification module 17 needs to include a coil 171, and the coil 171 is communicated with the storage cavity through a liquid outlet pipe, and a certain area is enclosed by the coil 171 due to the structure of the coil 171, so that in order to make full use of space, as shown in fig. 1, the filter cavity 18 is disposed in the area surrounded by the coil 171 in this embodiment.

When in use, the cavity cover 182 can be detached, then the gas filtering layer 186 is taken out for replacement or cleaning, and the cavity cover 182 and the cavity 181 can be connected in a pressing and buckling mode.
Further, the gasification device further comprises a cover 19, the cover 19 is covered on the gasification assembly 17, the lower end of the cover 19 is connected with the bottle body 1, an air inlet groove 191 corresponding to the gasification assembly 17 is arranged on the cover 19, and the air inlet groove 191 is arranged on the annular side and the upper side of the cover 19, so that a gas flow channel passing through the gasification assembly 17 is formed in the cover 19.
Liquid oxygen flows along the coil 171 after entering the coil 171 through the liquid outlet pipe, and gradually rises in temperature and gasifies in the flowing process. In order to improve the gasification temperature rising efficiency of the liquid oxygen in the gasification module 17, in this embodiment, the cover 19 is provided with an air inlet groove 191, the air inlet groove 191 is in a strip-shaped groove structure, in this embodiment, the air inlet groove 191 is provided on at least two side surfaces of the cover 19, namely, the annular side of the cover 19 and the upper end of the cover 19, and is located at a position corresponding to the gasification module 17. When the cap 19 is mounted to the bottle body 1, the entire gasification assembly 17 is located in the inner space of the cap 19, and the air inlet grooves 191 are opened on the side walls of the annular side and the upper side of the cap 19, so that a passage communicating with the outer space can be formed in the cap 19 through the air inlet grooves 191 on both sides, which serves as a gas flow passage in this embodiment.
After the liquid oxygen enters the gasification assembly 17, the temperature of the internal space of the cover 19 is reduced due to the low temperature of the liquid oxygen, so that a temperature difference is formed between the internal space of the cover 19 and the external space, and the air inlet grooves 191 on two sides of the cover 19 are formed, so that a gas flow channel is formed in the cover 19, and under the action of the temperature difference between the inside and the outside, the low-temperature gas in the internal space of the cover 19 flows towards the external space through the air inlet grooves 191, thereby avoiding the reduction of the temperature of the internal space of the cover 19 and affecting the gasification temperature rising efficiency of the liquid oxygen. And under the action of the air inlet groove 191, the inner space of the cover body 19 generates gas flow, and the gasification temperature rise of liquid oxygen can be quickened under the action of the gas flow, so that the efficiency is improved.
The present embodiment achieves the purpose of forming a gas flow channel in the inner space of the cover 19 by using the air inlet channel 191, and the external air enters the cover 19 through the air inlet channel 191 on one side in the process of passing through the gasification assembly 17, and flows out through the air inlet channel 191 on the other side after exchanging heat with the gasification assembly 17, thereby achieving the technical effect of improving the gasification heating efficiency under the flowing action of the external air in addition to the long-flowing gasification heating by using the gasification assembly 17, and further solving the problem that the gasification heating effect of the liquid oxygen is limited when the coil 171 is simply used by the liquid storage device in the related art.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art.
