The invention relates to cleaning type virtual reality glasses with a zooming function and for engineering design. The cleaning type virtual reality glasses include a main body, two concave lenses, and two control mechanisms; two focusing mechanisms and two dust removing mechanisms are arranged in the main body; and each focusing mechanism includes a first gear, an annular groove, a second gear, aconnecting rod, a third gear, a fourth gear, a vertical rod, a rack, a limiting groove and two limiting components. According to the cleaning type virtual reality glasses with the zooming function and for engineering design, the control mechanisms control the focusing mechanisms to drive the concave lens to move back and forth so as to adjust the focal length, and then a user can accurately adjust the focal length according to the myopia degree of the user, and the practicality of the virtual reality glasses can be improved; the dust removing mechanisms can remove dust from the concave lens while the user does not use the glasses, so that the user experience will not be lowered with the use of the virtual reality glasses, and the market competitiveness of the virtual reality glasses can be improved.
