Problems solved by technology
Due to the large resistance of the general conical cap, the air volume of the primary air is relatively small; the strip channel and the strip hole directly inclined to the axial direction make the secondary air intake resistance large and the air supply volume low, thus making the induction ratio low
Moreover, in order to allow the secondary air to enter, the tuyere generally protrudes from the ground during installation, or in order to prevent the tuyere from protruding from the ground, it needs to be fixed by a special tray, but the former affects the use of room functions, and the latter leads to complicated installation

Embodiment Construction
[0011] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.
[0012] Such as figure 1 , figure 2 As shown, the present invention mainly comprises outer tube 1, inner tube 2, secondary air intake tube 3, conical cap 4, tuyere cover 5 etc., and outer tube 1 is a diameter of D 1 cylinder, the upper end of the inner cylinder 2 is a diameter d 1 cylinder, the lower end of the inner cylinder 2 is a diameter from d 1 become d 2 The circular space between the outer cylinder 1 and the inner cylinder 2 is divided into several small partitions that are parallel to the axial direction and then inclined. The space between the small partitions and the walls of the inner and outer cylinders Clamp and seal. On the inner and outer cylinder walls adjacent to each strip channel 6, starting from the bottom of the inner cylinder, there are strip-shaped openings that are parallel to the axial direction and then inc...

An induced cyclone air-supplying pipe is composed of cylindrical external pipe, internal pipe consisting of cylindrical and conic segments, secondary wind inlet pipe, conic cap and pipe end cover. Several small isolating plates are used to divided the space between internal and external pipes into long channels which is first parallel with axis and then inclined. The long operings are made on the wall of internal and external pipes. The external pipe is surrounded by the secondary wine inelt pipe. The primary wine comes axially in it to generate cyclone and negative pressure and the secondary wind is sucked into internal pipe, where it is mixed with primary wind and the mixture is sprayed out in cyclone mode.
Description
Technical field: [0001] The invention relates to a swirl air supply port for each air-conditioned room in a central air conditioner, in particular an induced swirl air supply port suitable for a down-flow air-conditioning room, and belongs to the technical fields of building environment and equipment engineering and refrigeration engineering. Background technique: [0002] The development direction of modern air conditioners is good indoor air quality and low energy consumption. To achieve this, proper airflow organization is essential. Downflow air supply is a form of air supply developed in recent years that meets the above two conditions, but its airflow organization effect has a lot to do with its end air supply device (air supply port), which requires optimization of the end air supply device. [0003] The downward air supply mostly adopts the swirl type air supply port. In the prior art, there are many forms of swirl tuyere, and the more representative one is the int...
