Abstract

The invention discloses an air filter bottle for medical atomization self-cleaning filter screen, which comprises an inlet pipe and an outlet pipe. The inlet pipe is connected with a branch pipe, and the branch pipe is divided into two branch parts, each of which is A filter barrel is partly connected, and a filter screen is fixedly connected in the filter barrel. The top wall of the filter barrel is connected with a second connecting pipe and a third connecting pipe, and the two second connecting pipes are connected with a first Three connecting pipes and outlet pipes, the two third connecting pipes are evenly connected to branch pipes, the bottom of the filter bucket is connected with a fourth connecting pipe, both of the fourth connecting pipes are connected with the outlet pipes, and the filter bucket There is a backwashing device inside. The present invention has the function of self-cleaning filter screen, and by changing the change in the gas flow channel, it can realize different pipeline flow directions under normal operation and cleaning filter screen, and at the same time, it will not cause self-cleaning filter screen during atomization treatment The process of stopping the output of medicinal liquid, so as not to affect the treatment.

Description

technical field

[0001] The invention relates to the technical field of medical atomization devices, in particular to an air filter bottle for medical atomization self-cleaning filter screen. Background technique

[0002] Atomization refers to the operation of decomposing liquid into tiny droplets through a nozzle or high-speed airflow. Atomization treatment mainly refers to aerosol inhalation therapy. Atomization inhalation therapy is to disperse medicine into tiny mist droplets or particles with an atomization device. , make it suspended in the gas, and enter the respiratory tract and lungs, to clean the airway, humidify the airway, and achieve the purpose of local treatment and systemic treatment.

[0003] In the prior art, the atomized medicinal liquid is generally output by compressed air as the power, and in use, because the compressed air will contain dust or impurities in the air, it is often used when the compressed air enters. The filter will be used for filtering,...

Examples

Embodiment Construction

[0024] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention. Example reference Figure 1-6 , an air filter bottle for medical atomization self-cleaning filter net, comprising an inlet pipe 1 and an outlet pipe 7, the inlet pipe 1 is connected with a branch pipe 2, and the branch pipe 2 is divided into two branch parts, each branch part is far away from the inlet The end of the pipe 1 is connected with a filter barrel 8, and the filter barrel 8 is fixedly connected with a filter screen 9. The filter screen 9 is a cylindrical structure with a wide top and a narrow bottom. The cross-sections of the two symmetrical sides are vase-shaped. The top wall communicates with the second connecting pipe 4 and the third connecting pipe 5, the two second connecting pipes 4 communicate with each other and communicate with the first connecting pipe 3 and the outlet pipe 7 through the four-way connection, the two ends of the first co...
