Description

Filter press ring net piece Technical Field The utility model relates to a mesh, in particular to a filter press ring mesh, and belongs to the technical field of respirators. Background The filter screen of the breathing machine is an important component of the breathing machine and plays two main core functions of filtering and protecting. The filter screen can effectively filter out tiny particles such as dust, pollen, bacteria, viruses and the like in the air, ensures that the gas inhaled by a patient is clean and safe, is beneficial to reducing the risk of respiratory tract infection and improves the treatment effect. Meanwhile, the novel breathing machine can also protect internal components of the breathing machine, prevent impurities from entering and damaging, and prolong the service life of the breathing machine. Existing respirator filter mesh designs typically include two parts, a compression sheet and a filter sheet, which are bonded together with glue. During use, the glue releases harmful substances which enter the respiratory tract of a patient along with the operation of the breathing machine, and the substances pose a potential threat to the health of the patient. Meanwhile, the mode of glue bonding is unfavorable for tightening the filter disc, the filter disc needs to keep certain tension degree to ensure the filtering effect and stability of the filter disc, but the glue bonding is difficult to achieve an ideal tightening state, so that the filter disc is easy to loose or deform in the use process, and further the filtering efficiency and the service life are influenced. Disclosure of utility model In view of the foregoing, the present utility model provides a filter press ring mesh to solve or alleviate one of the technical problems in the prior art, and at least provides an advantageous choice. The technical scheme of the embodiment of the utility model is realized by comprising a filter press ring net piece, a filter assembly and a pressing assembly, wherein the filter press ring net piece comprises a first buckling assembly, the inner side wall of the first buckling assembly is provided with the filter assembly, the top of the filter assembly is provided with a second buckling assembly, and the first buckling assembly and the second buckling assembly are provided with the pressing assembly; The first buckle shell component comprises a lower buckle shell and a first through hole, wherein the first through hole is formed in the lower buckle shell; The second buckle shell component comprises an upper buckle shell and a second through hole, and the second through hole is formed in the upper buckle shell. It is further preferable that the filter assembly comprises a filter screen and filter holes, and the filter holes are uniformly formed in the upper surface of the filter screen. The pressing assembly comprises a first pressing ring, a second pressing ring, a first pressing groove and a second pressing groove, wherein the first pressing ring and the second pressing ring are fixedly connected to the inner side wall of the lower buckling shell, and the first pressing groove and the second pressing groove are formed in the bottom of the upper buckling shell. It is further preferable that the first pressing ring, the second pressing ring, the first pressing groove and the second pressing groove are in one of trapezoid, arc, triangle or rectangle, and the directions of the first pressing ring, the second pressing ring, the first pressing groove and the second pressing groove are longitudinally or obliquely arranged. It is further preferable that the first pressing ring is disposed opposite to the first pressing groove. It is further preferable that the second pressing ring is disposed opposite to the second pressing groove. It is further preferred that the first pressing ring is in snap connection with the first pressing groove, and the second pressing ring is in snap connection with the second pressing groove. It is further preferable that the pressing assembly comprises a first step and a second step, wherein the first step is fixedly connected to the inner side wall of the lower buckle shell, the second step is fixedly connected to the bottom of the upper buckle shell, and the first step and the second step are oppositely arranged. By adopting the technical scheme, the embodiment of the utility model has the following advantages: 1. According to the utility model, the two parts of the buckle shells are fixed in a welding or buckling mode, and the glue is not required to be used for bonding, so that the influence of harmful substances in the glue on the health of a patient when the breathing machine is used is avoided. 2. According to the utility model, the filter screen can be tightly pressed by the press ring and the press groove or by the mutual matching of the steps, so that the filter screen is ensured to be tight, the filter screen is prevented from loosening or deforming in the use p
