Description

Technical Field

[0001] The utility model relates to the technical field of slurry stirring and dust collecting devices for oxygen sensor chips, and more particularly to a slurry stirring and dust collecting device for oxygen sensor chips. Background Art

[0002] In existing technologies, slurry stirring and dust collection devices for oxygen sensor chips face some challenges in operation and maintenance, especially in the design of the dust collection system. Existing devices often rely on dust collection pipes and dust collection pumps to complete the dust collection work. However, the connection and disassembly processes between these pipes are usually complicated and tedious, which brings inconvenience to the daily maintenance and emergency repairs of the equipment.

[0003] First, the cumbersome operations of connecting and disassembling pipes limit the efficiency of maintenance work. In existing technologies, due to the lack of effective quick connection and disassembly mechanisms, when the vacuum pipes need to be cleaned, replaced or repaired, operators often need to spend a lot of time and energy to complete these tasks, which not only prolongs the downtime of the equipment, but may also increase maintenance costs.

[0004] Secondly, the reliability of the pipe connection is crucial to the performance of the entire vacuuming system. In the existing technology, the structural design of many connection devices is too simple, which may lead to leakage at the connection. Leakage will not only reduce the vacuuming efficiency, but also may pollute the working environment and equipment, and may even affect the quality of the oxygen sensor chip.

[0005] In addition, although some devices designed to solve the above-mentioned problems have appeared in the prior art, the structures of these devices are generally still relatively simple and cannot guarantee the long-term stability of the connection structure. Such unstable connection may cause the pipeline to loosen during the vacuuming process, thereby affecting the overall performance and safety of the vacuuming system. Loose pipeline connections may cause a decrease in vacuuming efficiency and may even shorten the service life of the equipment. Utility Model Content
