Large-flux suction head filter element and processing technology thereof

Abstract

The large-flux suction head filter element comprises a filter element upper seat, a first clamping groove is formed in the middle of the bottom of the filter element upper seat, mounting grooves are formed in the two sides of the inner wall of the first clamping groove, gaskets are arranged on the inner walls of the two mounting grooves in a clamped mode, and connecting shafts are fixedly arranged in the middles of one sides of the two gaskets; a first thread groove is formed in the edge of the top end of the filter element upper seat. According to the large-flux suction head filter element, the clamping ring at the upper end of the elastic pipe is clamped through the first clamping groove in the bottom of the filter element upper seat, and the clamping buckle is locked in cooperation with the mounting groove in the upper end of the clamping ring, so that the whole device is mounted; and the connecting shafts on the two sides of the filter element upper seat are pressed to extrude the buckles in the mounting grooves to be separated under the action of the buffer springs, so that the clamping rings can be pulled out of the first clamping grooves, the elastic pipes are detached for cleaning and replacement, a user can conveniently replace the filter element by himself, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of suction head filter elements, in particular to a large-flux suction head filter element and a processing technology thereof. Background technique [0002] The traditional high-flux tip filter is mainly used in some medical or research industries to filter and purify the liquid absorption at the output end of the pipette. With the development of modern technology, the function and function of the pipette have been improved. Therefore, the function and quality of the tip filter at the output end also need to be further improved, so that it can better meet the needs of modern medical research and use; [0003] In the prior art, when designing and manufacturing the high-flux suction head filter element, most designers pay attention to the bearing capacity of the design device, so that the device does not require frequent replacement of the internal filter element under the action of long-term liquid suction, ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when designing and manufacturing the large-throughput suction tip filter element, most designers pay attention to the load-carrying capacity of the design device, so that the device does not need to replace the internal filter element at a high frequency under the action of long-term liquid absorption, but in use When the filter element at the upper end of the device is replaced, the installation steps at the upper end are relatively complicated, and the disassembly will be relatively responsible, which will increase the burden on the user and reduce the practicability of the device.
