The control mechanism of the variable-flow type air hole is arranged on the external side wall of the outer cylinder, which prevents the control mechanism from being damaged by outlet air of an air conditioner, and increases the service life on one aspect, and is more convenient to dismount and maintain on the other aspect.

Description

The flow-changeable air port

Technical field

The utility model relates to a kind of ventilation equipment, relates in particular to a kind of flow-changeable air port.

Background technology

Have the place of large space at waiting room, theater, physical culture pipe etc., generally all adopt vertical air conditioner or central air-conditioning by air-supply refrigeration or heating.The wind of sending as air-conditioning directly blows out from pipeline, and there are the following problems in meeting: in summer, what air-conditioning was sent is the bigger cold wind of proportion, can directly be delivered to the space bottom, and can't spread poor refrigerating efficiency to the upper strata; In winter, what air-conditioning was sent is the less warm braw of proportion, and range is shorter, and can swim in the upper strata, so that influence heating effect, in order to address this problem, people generally install the air port that can regulate at pipeline air outlet place.

Chinese patent 98227720.2 discloses a kind of variable flow pattern outlet, and by executing agency, valve disc, inner core, urceolus are formed.By executing agency, regulate the height of valve disc, can control the direction of air-flow, speed, thus in Various Seasonal, reach different air outputs.

The executing agency of above-mentioned variable flow pattern outlet is arranged at an end that is used for being connected with pipeline in air port, makes executing agency damage easily, and also very inconvenience of maintenance.

Summary of the invention

The utility model provides a kind of good looking appearance, flow-changeable air port easy to maintenance.

A kind of flow-changeable air port, comprise urceolus, inner core and be fixed on urceolus and inner core between annular homogenizing plate, have some through holes on the annular homogenizing plate for circulation of air, inner core inside is provided with the valve disc that an air capable of blocking flows through from inner core, described valve disc secured in parallel vertically runs through on the valve rod of inner core and urceolus one, and the lateral wall of described urceolus is provided with the controlling organization of an actuate valve stem and valve disc coaxial rotation.

Described inner core inside is provided with some annulars with the coaxial setting of inner core and decorates mouth, makes product more attractive in appearance, and air-out is more even.

Described inner core goes out that circular row has some spiral type blades on the outer wall, makes air-out disperse more, and air conditioner refrigerating or heating effect are better.

The controlling organization of the utility model flow-changeable air outlet is located on the lateral wall of urceolus, makes controlling organization avoid the infringement of air-conditioning air-out to it on the one hand, has increased its service life, and the dismounting maintenance is convenient on the other hand.

Fig. 2 is a flow-changeable shown in Figure 1 air port A-A profile;

Fig. 3 is the utility model flow-changeable air port valve disc structural representation when vertical.

The specific embodiment

As shown in the figure, a kind of flow-changeable air port, comprise urceolus 1 and inner core 2, it is fixedly connected that urceolus 1 and inner core 2 are located between them the annular homogenizing plate 3 of level by one, have many through holes 5 on the annular homogenizing plate 3 for circulation of air, through hole 5 diameter are decided according to the actual requirements, and operated by rotary motion is between 2～5cm, and the quantity of through hole 5 is decided according to diameter.

Inner core 2 inside are provided with the valve disc 4 of a circle, and the diameter of valve disc 4 is basic consistent with the internal diameter of inner core 2, and when valve disc 4 was in state with the axis normal of inner core 2, effectively shutoff inner core 2 was blocked air and flow through from inner core 2.

Valve disc 4 secured in parallel are on a valve rod 6 that vertically runs through inner core 2 and urceolus 1, the lateral wall of urceolus 1 is provided with the controlling organization 9 that an actuatable valve bar 6 rotates, when valve rod 6 rotates, drive valve disc 4 coaxial rotation simultaneously, valve disc 4 rotates and just can change the size of inner core 2 ventilation area or directly block the interior circulation of air of inner core 2.

The inside of inner core 2 also is provided with 2 annulars with inner core 2 coaxial settings simultaneously and decorates mouth 8, and this annular is decorated mouth 8 not only can increase the aesthetics of product, and can make the air-out of inner core 2 more even; Circular row has 8 spiral type blades 7 on the outer wall of inner core 2, and this spiral type blade 7 makes the air-out diffusion increase, thereby improves the refrigeration or the heating effect of air-conditioning.

When using above-mentioned flow-changeable air port, only need its air intake is connected with an end of pipeline, the other end of pipeline is connected with air-conditioning.During summer, rotate valve disc 4, make the axis normal of valve disc 4 and inner core 2, the circulation of air in the blocking-up inner core 2, cold wind can only blow out from the through hole 5 on the annular homogenizing plate 3, thereby forms good attaching and diffusion property.During winter, make valve disc 4 parallel with the axis of inner core 2, the circulation of air in the complete opening inner core 2, because the passage of inner core 2 is big, the air velocity of flowing through is very fast, can improve the range of warm braw, thereby makes the air conditioning and heating better effects if.
