A vacuum cleaning head

Abstract

one. Vacuum cleaner head comprising: a pressure chamber, containing the first part of the camera and the second part of the camera, made with the possibility of movement relative to the first part of the camera, in response to pressure drops from different sides of the chamber, from the first position to the second position; and - control mechanism, located inside the pressure chamber and having a first state to restrain the movement of the second part of the chamber, in response to the above pressure drop, for the third position, which is intermediate between the first and second positions; and the second state allowing the second part of the camera to move, in response to the above pressure drop, in the second position; moreover, the control mechanism is configured to change its state between the first and second states in response to the movement of the second part of the camera from the third position. The vacuum cleaner head according to claim 1, in which the control mechanism is configured to change its state between the first and second states in response to the movement of the second part of the chamber from the third position in the direction of the first position. The vacuum cleaner head according to claim 1, in which the control mechanism is configured to accept the first state when the pressure drop from different sides of the second part of the chamber is essentially absent. The vacuum cleaner head according to claim 1, in which the control mechanism comprises an element with a guide channel attached to the first part of the pressure chamber, and a driven element configured to move together with the second part of the chamber to move relative to the element with the guide channel, the element with a guide channel contains

  1. 1
    The head of the vacuum cleaner, comprising:1. Головка пылесоса, содержащая:
  2. 2
    2 - a pressure chamber having a first chamber and a second portion of the chamber operable to move relative to the first part of the chamber in response to pressure drop from different sides of the camera, from the first position to the second position;and 2. - напорную камеру, содержащую первую часть камеры и вторую часть камеры, выполненную с возможностью перемещения относительно первой части камеры, в ответ на перепад давления с разных сторон камеры, от первого положения ко второму положению;и
  3. 3
    - the control mechanism, located within the pressure chamber and having a first state to inhibit movement of the second part of the chamber in response to said pressure differential for a third position which is intermediate between the first and second positions;and a second state, which allows the second portion of the chamber to move in response to said pressure differential to a second position;3. - управляющий механизм, расположенный внутри напорной камеры и имеющий первое состояние для сдерживания перемещения второй части камеры, в ответ на вышеуказанный перепад давления, за третье положение, являющееся промежуточным между первым и вторым положениями;и второе состояние, позволяющее второй части камеры перемещаться, в ответ на вышеуказанный перепад давления, во второе положение;
  4. 4
    The control mechanism being configured to change their state between the first and second states in response to movement of the second part of the chamber from the third position. 4. причем управляющий механизм выполнен с возможностью изменения своего состояния между первым и вторым состояниями в ответ на перемещение второй части камеры из третьего положения.
  5. 20
    17. A vacuum cleaner comprising a main body connected to a cleaner head according to any one p.p.1-16. 17. Пылесос, содержащий главный корпус, соединенный с головкой пылесоса по любому из п.п.1-16.
