Compressed air atomizer connecting device

Abstract

The invention discloses a compressed air atomizer connecting device. The device comprises an atomizer main machine 1, a connecting pipe 2 and an atomizing cup 3, wherein an atomizing nozzle 1-1 is formed in the atomizer main machine 1; the connecting pipe 2 comprises a joint; the atomizing nozzle 1-1 is formed in a body shell of the atomizer main machine 1; the joint comprises a first connector 2-1 and a second connector 2-2; the first connector 2-1 is connected with the atomizing nozzle 1-1; the second connector 2-2 is connected with the external equipment atomizing cup 3; and the atomizing nozzle 1-1 is connected with the first connector 2-1 in an internal wrapping manner. The device has the beneficial effects that the problem of atomizing nozzle rupture caused by inserting and pulling out the joint of the connecting pipe multiple times is solved, thus obviously prolonging the service lives of compressed air atomizers, especially the compressed air atomizers which have high frequency of use and are used in hospitals, and avoiding the problem that atomization inhalation can not be carried out because of atomizing nozzle rupture.

Description

technical field [0001] The invention relates to a medical device, in particular to a spray port of a compressed air atomizer and a connecting pipe joint device thereof. Background technique [0002] In the current compressed air atomizer, the connection between the spray port and the connecting pipe joint is to use the connecting pipe joint to cover the spray port and connect the air. When the connecting pipe joint needs to be plugged and pulled out frequently, the spray port will break. , resulting in inability to atomize treatment. The existing solution is to thicken the spray port, but since the present spray port is made of plastic injection molding, an oversized thickened spray port will cause the plastic inside the spray port to shrink and produce shrinkage cavities, which will reduce its own strength and affect the service life; or want to It is necessary to add a reinforcement structure around the existing spray port, but this will cause the atomization connection p...

Problems solved by technology

[0002] In the current compressed air atomizer, the connection between the spray port and the connecting pipe joint is to use the connecting pipe joint to cover the spray port and connect the air. When the connecting pipe joint needs to be plugged and pulled out frequently, the spray port will break. , resulting in the inability to aerosolize the treatment

The existing solution is to thicken the spray port, but since the present spray port is made of plastic injection molding, an oversized thickened spray port will cause the plastic inside the spray port to shrink and produce shrinkage cavities, which will reduce its own strength and affect the service life; or want to It is necessary to add a reinforcement structure around the spray port, but this will cause the atomization connection pipe joint to not completely cover the spray port

In summary, the existing solutions cannot completely solve the defect that the spray port of the compressed air atomizer and its connecting pipe joints are often plugged and pulled out, which are easy to break
