As a preferred solution, the inner wall of the cylinder is in close contact with the outer wall of the outer box of the heating device.

As a preferred solution, the heating device is provided with a gear switch for controlling and adjusting the heating temperature.

As a preferred solution, the air inlet pipe extends into the humidification inner cavity from the air inlet, and a gas diffuser for dispersing oxygen is provided at the bottom end of the air inlet pipe.

As a preferred solution, the top of the humidification bottle is provided with a safety structure that can prevent the humidification bottle from bursting due to blockage of the air outlet or the filter device.

As a preferred solution, a one-way valve is provided at the air inlet.

Compared with the prior art, the present invention has obvious advantages and beneficial effects. By installing a detachable heating device, the humidification bottle can be conveniently and quickly heated according to needs, so as to ensure that the oxygen passing through the humidification bottle can meet the needs of patients. The suitable temperature required in the process of oxygen therapy can effectively improve the therapeutic effect of oxygen therapy. By arranging a multi-layer filter and purification device between the humidification inner cavity and the air outlet, the filter and purification device can effectively eliminate water droplets in the oxygen flow and filter microbial pathogens with a size of 0.5 micron or more in the oxygen flow. On the one hand, it can ensure that the oxygen in the air outlet has a certain humidity, and at the same time effectively prevent the water droplets in the oxygen flow from being brought into the air outlet into the patient's body due to too fast oxygen intake rate, so that the patient's oxygen inhalation is more gentle and willing to continue Receive oxygen therapy. On the other hand, it can effectively prevent the symptoms of respiratory tract infection caused by the inhalation of microbial pathogens in patients.
