DETAILED DESCRIPTION

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Fig. 1 to Fig. 3, an air outlet mechanism without front blades comprises a shell, a rear blade group 5 fixed in the shell, and a rear connecting rod 8 connecting the rear blade group 5, wherein one or both sides of the blades in the rear blade group 5 are provided with a rib structure 5.1, one side of the shell is provided with a bent rod connecting mechanism 7, the bent rod connecting mechanism 7 comprises a bent rod 7.1, the bent rod 7.1 is provided with a first port 7.4, a second port 7.2, a third port 7.3 and a bent rod fixing hole 7.5, the lower shell 3 is provided with a bent rod connecting shaft 7.6, through the bent rod connecting shaft 7. 6 is connected with the bent rod fixing hole 7.5 to realize the connection between the bent rod connecting mechanism 7 and the lower shell 3, the first port 7.4 is connected with the dial button 6, the second port 7.2 and the third port 7,1 are respectively connected with the air door 4 and the transmission mechanism 11, and the transmission mechanism 11 is connected with the rear blade group 5. When the dial button 6 is dialed up and down, the second port 7.2 is driven to rotate, thereby driving the air outlet direction angle of the air door to be adjusted up and down; when the dial button 6 is dialed left and right, the third port 7.1 is driven to move left and right, thereby driving the transmission mechanism 11 to move, and driving the air outlet angle of the rear blade group 5 to be adjusted left and right.

In this embodiment, as shown in Figures 4 to 7, the rib structure 5.1 is a convex arc structure or a heart-shaped structure, which plays a guiding role in the wind direction. The transmission mechanism 11 includes a connecting gear 10 and a rear blade gear 9 meshing with the connecting gear 10; the connecting gear 10 is provided with a first rotating shaft 10.1, the first rotating shaft 10.1 is connected to the third port 7.3, and the rear blade gear 9 is connected to one of the rear blades through the second rotating shaft 9.1. The third port 7.3 is connected to the first port 7.4. The third port 7.3 is a long strip opening, which is convenient for adjustment when dialing. The shell includes an upper shell 2 and a lower shell 3. The area of the upper shell 2 and the lower shell 3 that wraps the rear blade group is a circular or arc structure, which helps the wind direction to reflect a certain direction through the arc when passing through the circular structure. The shell is provided with a panel 1. The shell is provided with a connecting hole for mounting the rear blade group. The damper includes a rotating shaft 4.3 and a face door 4.4 connected to the damper rotating shaft 4.3. The two ends of the damper rotating shaft 4.3 are respectively provided with fixed shafts 4.2, which are respectively connected to the housing and the connecting shaft 4.1. The connecting shaft 4.1 is connected to the second port 7.2. The housing is provided with a connecting hole for installing the rear blade group 5. The rear connecting rod is provided with a group of fixing holes, and each blade of the rear blade group 5 is provided with a card slot for fixing and installing the rear connecting rod. The bent rod connecting mechanism 7 is fixed to the outer side of the housing through the connecting shaft 4.1 on the damper 4 and the third port 7.3. The housing is provided with a hole for the dial button 6 to be toggled, which is used as a space for the dial button 6 to slide.

In this embodiment, the ribs in the rear blades help direct air upward and downward, and the damper will block the air in the upward or downward direction, allowing air to flow in one direction: considering the feasibility of manufacturing and assembly, the housing is divided into two parts, the upper housing 2 helps the airflow in the downward direction, and the lower housing 3 helps the airflow in the upward direction. The dial button 6 swings up/down according to the needs of the customer, and can also swing left and right to control the left and right swing angle of the rear blade. The bent rod connection mechanism 7 connects the rear blade group 5, the damper 4 and the transmission mechanism 11 to each other.

As shown in 8 and 9, the arrow represents the wind direction. As shown in FIG8, when the dial button 6 is turned upward, the entire connecting mechanism 7 rotates clockwise with the crank connecting shaft 7.6 as the center, and the crank 7.1 moves clockwise downward to drive the connecting shaft 4.1 to rotate counterclockwise downward, thereby synchronously driving the damper rotating shaft 4.3 to rotate counterclockwise, so that the face door 4.4 rotates upward. At this time, the damper 4 will prevent the air from flowing above and allow the air to flow below. The rib structure and the circular shell guide the wind direction so that the wind can be directed upward when it is discharged from the panel. As shown in FIG9, when the dial button 6 is turned downward, the entire connecting mechanism 7 rotates counterclockwise with the crank connecting shaft 7.6 as the center, and the crank 7.1 rotates counterclockwise upward to drive the connecting shaft 4.1 to rotate clockwise upward, and the face door 4.4 rotates clockwise synchronously. At this time, the damper 4 will prevent the air from flowing below and allow the air to flow above. The rib structure and the circular shell guide the wind direction so that the wind can be directed downward when it is discharged from the panel.

As shown in Figures 2 and 4, when the dial button 6 slides to the left, the crankshaft 7.1 moves to the left, so that the third port 7.3 drives the first rotating shaft 10.1 to the left, so that the connecting gear 10 rotates counterclockwise, thereby driving the rear blade gear 9 and the second rotating shaft 9.1 to rotate clockwise, and the second rotating shaft 9.1 drives the rear blade to rotate to the left, and at the same time drives the rear connecting rod 8 to drive the rear blade group 5 to rotate to the left by an angle. When the dial button 6 slides to the right, the crankshaft 7.1 moves to the right, so that the third port 7.3 drives the first rotating shaft 10.1 to the right, so that the connecting gear 10 rotates clockwise, thereby driving the rear blade gear 9 and the second rotating shaft 9.1 to rotate counterclockwise, and the second rotating shaft 9.1 drives the rear blade group 5 to rotate to the right by an angle. The connecting shaft 4.1 and the first rotating shaft 10.1 have a certain length to slide on the card slot of the port, and the crankshaft connecting shaft 7.6 has a certain length to slide on the crankshaft fixing hole 7.5.

The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
