Embodiment 1
[0060] In this embodiment, the height detection switch is used to detect the limit position of the lifting height.
[0061] The height detection switch includes an upward limit switch 4 and a downward limit switch 5 . Such as Figure 2-4 As shown, the down limit switch 5 is installed on the upper end of the lower body 2 of the air handling device. Such as image 3 , Figure 5 combine Image 6 As shown, the upward limit switch 4 is arranged in the base 42 of the lifting mechanism 31. Specifically, the upward limit switch 4 is installed on the guide rod fixing base, on the side relative to the lifting motor 34, and the trigger of the switch 51 towards the lifting motor 34. Whether the air handling unit reaches the highest point or the lowest point is detected by the upper limit switch 4 and the lower limit switch 5 .
[0062] Under the action of the lifting unit 3, the air handling unit rises to the highest point, such as image 3 , Figure 4 combine Figure 5 As shown,...
Embodiment 2
[0066] In this embodiment, the height detection switch is also used to detect the limit position of the lifting height.
[0067] The height detection switch includes an upward limit switch 4 and a downward limit switch 5 . Compared with the height detection switch in Embodiment 1, the placement position and working principle of the upward limit switch in this embodiment are exactly the same as those in Embodiment 1, and will not be repeated here.
[0068] Such as Figure 6-7 As shown, the difference from Embodiment 1 is that the downward limit switch 5 in this embodiment is also placed in the base 45 of the lifting mechanism. Now, the placement position and working principle of the downward limit switch will be described.
[0069] The down limit switch 5 is arranged in the lower main body 2 on the same side as the lifting motor 34 , and the trigger piece 51 of the down limit switch 5 faces the up limit switch 4 . Under the action of the lifting unit 3, the air handling unit ...
Embodiment 3
[0072] In this embodiment, the height detection switch is used to detect a certain height position of the purification unit in the whole lifting height.
[0073] Such as Image 6 As shown, the structure of the code disc 40, the optical couple 41, the driving screw 38, and the driving nut 37 is used to detect the height position of the lifting mechanism 31 during the lifting process. Such as Figure 5 As shown, the elevating mechanism 31 uses the structure of a cross bracket, one end (end A) of the bracket is fixed, and the whole mechanism is lifted and lowered by moving the other end (end B) horizontally, that is, through the motor, the reduction box 35,39, the transmission screw 38 1. The movement of the transmission nut 37 realizes the horizontal movement of one end (end B) of the support. A pair of optical couple 41 and code disc 40 can measure the rotational speed of the motor during work, and then measure the direction of rotation and the number of turns of the motor du...
