This utility model relates to the field of ventilation therapy equipment and discloses an oxygen concentrator that does not require an internal battery. It includes: an adsorption tower with an oxygen outlet; an oxygen tank configured to receive and store oxygen produced by the adsorption tower from the outlet; a control component including a pulse valve located at the oxygen supply end of the oxygen tank, the pulse valve being controlled to open during the user's inhalation and close during exhalation to form a pulsed oxygen supply; and a power connection component configured to connect to an external power source, which serves as the sole power source for the oxygen concentrator. The pulse valve design prevents oxygen waste caused by outputting oxygen during the user's exhalation. Compared to oxygen concentrators that provide continuous oxygen supply, this battery-free oxygen concentrator is smaller and more convenient, effectively mitigating the inconvenience caused by the large size of traditional oxygen concentrators, while maintaining the same amount of oxygen inhaled by the user.

This utility model provides a self-cleaning device for an oxygen concentrator filter, relating to the field of oxygen concentrator cleaning. It includes a housing with a filter screen fixedly embedded in its front side. A sleeve is fixedly connected to the inner wall of the housing, and a negative pressure fan is fixedly connected to the surface of the sleeve. A three-way pipe is fixedly connected to the top of the negative pressure fan.
