Simulation demonstration mechanism of for dustproof mask effect display

Abstract

The invention relates to a simulation demonstration mechanism of for dustproof mask effect display. The mechanism comprises a demonstration cabinet with a right opening and a dust cabinet hermeticallyarranged on the left side of the demonstration cabinet; the demonstration cabinet is provided with a communication port communicated with the dust cabinet, and material clamping air cylinders are embedded into the upper wall and the lower wall of the communication port; the material clamping air cylinders are connected with material clamping blocks matched with a filter element column, and a comparison plate matched with the communication port is arranged in the demonstration cabinet; the comparison plate comprises a comparison frame and a dust collection and ventilation comparison block embedded in the center of the comparison frame; a ventilation intercepting device is arranged at the position, on the lower side of the communication port, of the dust cabinet; a dust blowing air pump isarranged at the bottom of the dust cabinet, and a dust inlet opening and closing plate with a handle is installed on the upper portion of the dust cabinet. According to the mechanism, the material clamping parts are matched through the communication port so that the filter element column and a comparison part composed of a cylinder and a mask can be clamped, the comparison block is designed so that the comparison effect of the filter element column and the mask can be visually reflected, and the teaching demonstration effect is achieved for students.

Description

technical field [0001] The invention relates to the field of teaching demonstration equipment, in particular to a simulation demonstration mechanism for displaying the function of a dust mask. Background technique [0002] Most of the students in school are learning theoretical knowledge. How to let students intuitively understand the role of factory protective equipment, so that students can wear factory protective equipment after entering the factory. Factory protective equipment mainly includes leather shoes, safety helmets, gloves, and dust masks. etc. Especially in some casting and forging workshops, dust masks are very important, but most students think that they only need to go to the workshop for inspection after entering the factory. Harmful dust will enter the oral cavity, which will affect the health status. In order to better teach students to wear dust masks, it is urgent to design a dust mask (core component filter core column) and mask filtering effect. Compa...
