TH850C3 - Adjustable air intake device - Google Patents

Abstract

An adjustable air intake device for increasing the blowing power of the main air flowing through the guide pipe (13) includes a cylindrical articulation section (10) positioned at the end of the guide pipe (13) to limit space. Of the annular gap (16), the enclosed support assembly (20) is firmly positioned in the annular gap (16), and there are several internal recesses (28) that are shifted by angle between them. The enclosed jamb assembly (30) has multiple external compartments (38) and rests on and rotates relative to the support assembly (20) through the motor driven actuator assembly (40). To adjust the area Resting on top of the external and internal compartment (28,38), which in this way adjusts the volume The air stream is brought in through the annular gap (16).

Claims (6)

1.Adjustable air intake device for increasing the blowing power of the main air stream at It flows through the guide pipe, which is limited by the cylindrical wall. Which this cylindrical wall includes The end part that surrounds it to define the outlet port for delivering the main beam. Where such an adjustable air intake device has the following components Cylindrical splice Which has an inner perimeter wall that surrounds the axis and which limits The area of the conduit that is adjusted to be positioned at the end of the guide pipe. With the walls surrounding the interior It includes the near and far enclosures relative to the distal end. The enclosures and the surrounding enclosures will be adjusted to be enclosed and positioned remotely. From the apex enclosed in a radial direction, with a ring-shaped gap in between. The enclosed support assembly Which includes the part that is The one inner border was placed around the axis and adjusted to overlap. The end that surrounds The first outer edge, which is opposite the one in the inner edge. Radial direction and is positioned to overlap the nearby enclosures. The enclosed support area is inserted between the two edges and is made to be The same unit with one such inner and outer rims. Such an enclosed support assembly that has multiple internal compartments to be positioned. In the enclosed support area to be connected to the said guide pipe and to be shifted at an angle Back and forth between each other around the axis The pieces that surround the jamb, including the part that are The second inner rim that was placed around the axis and adjusted to be positioned next to the The end that surrounds The second outer edge, which is opposite the second inner edge, in Radial direction and is placed next to the nearby enclosures. The enclosed jamb area is inserted between the two edges. And was created to be The same unit with the second inner and outer rims. The pieces of the frame that surround it Which has several external compartments which will be placed In the enclosed mechanical region and which is shifted back and forth between each other around the axis, where The enclosing sash assembly is positioned relative to above and rotated. With the supporting assembly that surrounds it around the axis between the fully open positions where such external slots coincide with the respective internal slots. And the partially open position, where such external channels partially overlap, respectively, and the motor-driven actuator assembly positioned to initiate the motion. The rotary type of the sash assembly that surrounds it around the axis between the fully open positions. And partially open positions 2. The equipment specified in claim 1, provided that the surrounding supporting assembly There is still a curved key notch positioned in the support area surrounding it and spanning it. The edge around the outside that one. And the pieces of the frame that surround there are still The pilot key is placed on the surrounding jamb and leads out to the The keyed groove is said to guide the rotational motion of the jamb assembly. Surround such 3.The device is specified in claim 1, where the actuator driven by such motor will Including the part that is The motor is placed on the said cylindrical coupling and has an output shaft. Which will lead out in a direction parallel to the axis The curved comb gear is placed on top of the enclosed jamb next to the periphery. The aforementioned second outer and the pinion gear (round gear) were installed and driven by the said output shaft. And was placed in coordination with the gear comb to convey the thrust of the shaft. Sent the power to turn the assembly of the jamb around it. 4. Equipment as specified in claim 3, provided that the enclosing frame assembly will Is positioned so that it can rotate further in relation to the supporting assembly that surrounds it around the axis. To a closed position Where each such external channel and each said internal channel Corresponding overlap from each other 5.The equipment described in claim 4 still contains deterrent assemblies. That are positioned to suppress the motor actuator When a piece of a jamb The surround will reach a fully open and closed position. Which thread this method will stop The rotational motion of the surrounding jamb assemblies. 6. The device is described in claim 5, where the restraining element will Including the part that is The contact parts are placed on and slide with the enclosing sash assembly and the first and second microswitches installed on the enclosed support. Next to the second outer edge And which have first and second touch points respectively They are arranged so that when the enclosing jamb assembly is in the fully open position, the first touch point touches the contact to relay a stop signal. The operation of such motors and provided that when the enclosing jamb assembly is in the closed position, the second such contact point touches the contact to convey. Signal to stop operating the motor
