Description

M247544 V. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to a vacuum pumping structure of a container lid, particularly a container lid structure capable of automatically pumping, which mainly uses a suction device, The lid detection device, the vacuum detection device, and the pressure relief control device constitute a vacuum suction structure of the container cover, which is characterized by it, thereby promoting the container cover to achieve automatic air extraction, self-detection, safe power-off, and continuous Vacuum and easy to use. [Previous technology] Traditional fresh-keeping sealed containers can contain food or precision appliances in it, and with a one-way valve of a suction pump through the lid, the air 4 in the fresh-keeping sealed container is drawn out to form a negative pressure fastening adsorption cover. However, it has the following disadvantages when it is used in actual sealing and operation: 1. The suction pump used in conjunction with it is difficult to maintain air tightness with the cover during operation, so the effect of air extraction is not good, or Leakage due to shaking and loss of suction. 2. The one-way valve and other air-tight structure of the lid of the fresh-keeping sealed container still cannot maintain the vacuum negative pressure in the sealed container due to the unavoidable capillary phenomenon, resulting in incomplete sealing. Therefore, how to develop a vacuum pumping structure that is different from the traditional fresh-keeping sealed container, makes the vacuum pumping operation more convenient, and provides the function of continuous vacuum negative U pressure and reliable sealing, which is a new product that consumers are looking forward to. , Is also the goal of the relevant industry to work hard to develop.
