Intelligent negative-pressure air suction and collection device

Abstract

The invention provides an intelligent negative-pressure air suction and collection device, which comprises a vacuum pump, a vacuum pressure regulating valve, a vacuum two-way valve, a vacuum filter and a vacuum collection cavity which are sequentially connected through pneumatic hoses. The device further comprises a two-way valve controller which is in control connection with the vacuum two-way valve. The vacuum pressure regulating valve is used for controlling the flow of air flowing into a system, a pressure sensor used for sensing the quality of tea buds collected in the vacuum collecting cavity is arranged at the outer bottom of the vacuum collecting cavity, the vacuum pressure regulating valve and the pressure sensor are connected with an upper computer separately, and the upper computer is in control connection with a two-way valve controller. When the air flow and the quality of tea buds collected in the vacuum collecting cavity reach preset values, the vacuum pressure regulating valve and the pressure sensor send signals to the upper computer, and then the upper computer sends instructions to the two-way valve controller to control switching-on and switching-off of the vacuum two-way valve. The intelligent negative-pressure air suction and collection device is small in mass and size, the tea buds can be automatically sucked for several times per second, and the collection device is convenient to carry.

Description

technical field [0001] The invention belongs to the technical field of negative pressure suction equipment, and in particular relates to an intelligent negative pressure suction collection device. Background technique [0002] The vacuum suction collection device can extract the air in the vacuum collection chamber, so that the collection chamber is in a vacuum state, and at the same time, the trachea mouth at one end of the collection is in a negative pressure state, so as to achieve the purpose of absorbing light and small objects. The sucked objects enter the collection cavity, and since the collection cavity is in a vacuum state, the collected items can be stored for a longer time in a vacuum environment. [0003] When starting to inhale, it is necessary to ensure that all links inside the system are sealed and connected, and the collection chamber is also in a sealed state, so that the air in the collection chamber can be sucked clean to achieve a vacuum state. Once th...
