Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0018] like figure 1 As shown, a waterproof device for an outdoor box body of a projector includes an outdoor box body 1 , a waterproof baffle 5 , and an air outlet filter 8 . A waterproof baffle 5 is arranged at the air outlet of the outdoor cabinet 1, so as to prevent water from entering the outdoor cabinet of the projector when the air is exhausted. An air outlet filter 8 is provided under the waterproof baffle 5 of the air outlet of the outdoor box 1 for filtering large particle pollutants, dust and blisters in the air.

[0019] The waterproof baffle 5 can effectively block outdoor moisture from entering the box. When the outdoor box of the projector is installed, the waterproof baffle 5 can ensure that the outdoor box of the projector does not enter water when the installation angle of the outdoor box is changed from 0° to 90°, so as to better en...

Abstract

The invention relates to the waterproof device of a projector outdoor box. The device comprises the outdoor box. The air outlet of the outdoor box is provided with a waterproof baffle plate so that water can be prevented from entering into the projector outdoor box during air exhausting. An air outlet filter screen is arranged below the waterproof baffle plate of the air outlet of the outdoor boxand is used for filtering large particles of pollutants, dust and bubbles in the air. Through a waterproof design in the invention, moisture is effectively prevented from entering into the projector outdoor box, and pollutants in the air can also be effectively prevented from entering into the box. The waterproof device can be used to fully protect the projector outdoor box, the service life is prolonged and maintenance cost is saved.

Description

technical field [0001] The invention relates to an outdoor box of a projector, in particular to a waterproof device of the outdoor box of a projector. Background technique [0002] At present, electronic and electrical cabinets (cabinets) are widely used in all walks of life, many of which are installed outdoors. In harsh conditions, the cabinets are under the erosion of rainwater for a long time, so the materials and waterproofing of the products have higher requirements. Requirements, how to provide an outdoor waterproof box structure that meets the IP65 standard and can meet the heat dissipation requirements of high-power electrical appliances is a technical problem to be solved urgently in the industry. As a new type of waterproof technology, outdoor box waterproof technology can effectively reduce the water entering the outdoor box and prevent dust in the air from entering the box. It has become a very effective outdoor box waterproof technology. In the past, when the ...
