Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum negative pressure fans, in particular to a vacuum negative pressure fan cabinet structure. Background Art
[0002] Vacuum suction cups or platforms are common devices in inkjet printing, mechanical manufacturing, and sheet metal processing. They are used to absorb and secure workpieces for precise processing or manipulation. In these applications, the stability and reliability of vacuum pressure are crucial, as they directly impact the quality and efficiency of the process.
[0003] Existing technical solutions: Existing solutions primarily rely on vacuum generators or vacuum negative pressure blowers to provide vacuum negative pressure. Vacuum generators use compressed air as a medium to indirectly generate vacuum negative pressure, while vacuum negative pressure blowers use a fan as a negative pressure source to directly provide negative pressure. Both devices have their advantages and disadvantages.
[0004] Problems with existing technologies: However, existing vacuum negative pressure equipment has some problems. First, the vacuum negative pressure generated by the vacuum generator is affected by the external air source, and the negative pressure value is unstable, which may cause problems when a large amount of vacuum negative pressure is required. Secondly, although vacuum negative pressure fans can directly provide negative pressure, conventional negative pressure fans are directly exposed to the environment and lack complete supporting heat dissipation and detection functions, resulting in high noise, insufficient aesthetics and functionality. In addition, the versatility of these two types of equipment is not strong enough and cannot adapt to a variety of different working environments and conditions. Utility Model Content
