Abstract
1. Камера пыли для испытания электронного прибора, содержащая:корпус, вмещающий пыль;монтажный стол для размещения электронного прибора в корпусе;первую воздуходувку для рассеивания пыли по всему корпусу в течение первого периода испытания; ивторую воздуходувку для выдувания закрепившейся на вентиляционном отверстии электронного прибора пыли в течение второго периода испытания, более продолжительного по сравнению с первым периодом.2. Камера пыли по п.1, в которой вторая воздуходувка подает воздух к вентиляционному отверстию, изменяя направление подаваемого воздуха в течение второго периода испытания.3. Камера пыли по п.2, в которой вторая воздуходувка изменяет направление подаваемого воздуха в пределах заданного угла поворота, при этом ось поворота направлена к вентиляционному отверстию.4. Камера пыли по п.1, в которой первая воздуходувка подает воздух к нижнему участку корпуса, изменяя направление подаваемого воздуха в течение первого периода испытания.5. Камера пыли по п.4, в которой первая воздуходувка изменяет направление подаваемого воздуха в пределах заданного угла поворота, при этом ось поворота направлена к нижнему участку корпуса.6. Камера пыли по п.1, в которой нижний участок корпуса имеет коническую форму.7. Камера пыли по п.1, дополнительно содержащая третью воздуходувку, которая расположена на нижнем участке корпуса и периодически подает воздух к верхнему участку корпуса.8. Камера пыли по п.1, в которой вторая воздуходувка содержит соединительную трубу, которая способна поворачиваться вокруг своей оси, и форсунки, закрепленные на соединительной трубе.9. Камера пыли по п.1, в которой первая воздуход�1. A dust chamber for testing an electronic device, comprising: a housing containing dust; an installation table for placing the electronic device in the housing; a first blower for dispersing dust throughout the housing during the first test period; and a second blower for blowing dust fixed on the ventilation hole of the electronic device during the second test period, longer than the first period. 2. The dust chamber according to claim 1, in which the second blower supplies air to the ventilation hole, changing the direction of the supplied air during the second test period. The dust chamber according to claim 2, in which the second blower changes the direction of the supplied air within a predetermined angle of rotation, while the axis of rotation is directed to the ventilation hole. The dust chamber according to claim 1, wherein the first blower delivers air to the lower portion of the housing, changing the direction of the supplied air during the first test period. The dust chamber according to claim 4, in which the first blower changes the direction of the supplied air within a predetermined angle of rotation, while the axis of rotation is directed to the lower portion of the housing. The dust chamber according to claim 1, in which the lower portion of the housing has a conical shape. The dust chamber according to claim 1, further comprising a third blower, which is located in the lower portion of the housing and periodically supplies air to the upper portion of the housing. The dust chamber according to claim 1, wherein the second blower comprises a connecting pipe that is able to rotate about its axis, and nozzles mounted on the connecting pipe. The dust chamber according to claim 1, in which the first blower
