Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an atomizing filter. Background Technology

[0002] Nebulized inhalation therapy is an important and effective treatment method for respiratory diseases. It uses a nebulizer to atomize liquid medication into tiny particles, which are then inhaled into the respiratory tract and deposited in the lungs, thus achieving painless, rapid and effective treatment. The principle is based on the Venturi jet principle, which uses compressed air to form a high-speed airflow through a narrow tube. The resulting negative pressure carries liquid or other fluids to be sprayed onto an obstruction. Under high-speed impact, the fluid splashes around and turns into a mist of particles, which are then sprayed out from the outlet tube.

[0003] Research into existing technologies has revealed that current atomizers have filters installed at the air inlet to reduce impurities in the air. These filters require replacement after prolonged use, but the filter cartridges are easily attached inside the filter and cannot be removed by hand; they require tools such as tweezers or clamps for replacement, which is very inconvenient. Therefore, this invention proposes an atomizing filter. Utility Model Content

[0007] One end of the insertion tube has a groove, and a magnet is inserted into the inside of the groove.

[0008] Preferably, a hidden groove is provided at the center of the baffle, the ring is engaged inside the hidden groove, the hidden groove is connected to the slot, the outer diameter of the ring is adapted to the inner diameter of the insertion tube, and the inner diameter of the ring is smaller than the inner diameter of the insertion tube.

[0009] By adopting the above technical solution, the ring can be snapped into the inside of the hidden groove. Pulling the pull plate upwards will push the filter element in the insertion tube outwards through the ring, which facilitates the replacement of the filter element.

[0010] Preferably, the spring is a compression spring, the slide groove is a rectangular groove, there are two slide grooves, the two slide grooves are respectively located on the left and right sides of one end of the insertion tube, one end of the spring is welded to the pull plate, and the diameter of the spring is smaller than the wall thickness of the insertion tube.

[0011] By adopting the above technical solution, when the pull plate is pulled upward, the spring is compressed and contracts; when the pull plate is released, the decompressed spring can reset the pull plate and the ring.

[0012] Preferably, there are two pull plates, which are welded to the left and right sides of the ring respectively. The thickness of the pull plates is the same as the thickness of the ring, and the thickness of the pull plates is adapted to the depth of the slot.

[0013] By adopting the above technical solution, the pull plate can be hidden inside the slot without affecting the fit between the baffle and the atomizer.

[0014] Preferably, the filter element is a cylinder, the diameter of the filter element is adapted to the inner diameter of the insertion tube, one end of the filter element overlaps with the ring, the length of the filter element is less than the length of the insertion tube, and the air inlet is connected to the inside of the insertion tube.

A slot is provided on the side of the baffle near the pull plate. A circular ring is fixedly connected to one side of the pull plate, and a filter element overlaps on one side of the circular ring. When the filter element needs to be replaced, hold the pull block and pull the tube out of the atomizer's filter port. Pulling the pull plate upward will push the filter element out of the tube through the circular ring. When the pull plate is released, the decompressed spring will reset the pull plate and the circular ring. The old filter element can then be removed to replace the new one, achieving the purpose of quick filter element replacement.
