Example 1

Fig. 1 shows an exploded view of a fan according to an embodiment of the present utility model. Fig. 2 shows a side view of a fan according to an embodiment of the utility model. As shown in fig. 1 and 2, the air outlet assembly 100 of the present embodiment mainly includes a housing 1, a heat generating member 2, and a switching structure. Wherein, the shell 1 is provided with a first air outlet 11 and a second air outlet 12. The heat generating element 2 is arranged at the first air outlet 11. The switching mechanism is provided in the housing 1. The switching mechanism has a first state in which the first air outlet 11 is opened and the second air outlet 12 is closed, and a second state in which the second air outlet 12 is opened and the first air outlet 11 is closed. The switching mechanism is adapted to prevent wind from flowing through the heat generating element 2 when the switching mechanism is in the second state. Among them, the heating wire is preferably but not limited to a PTC heater, an electric heating wire, an infrared heater, or the like.

As can be seen from the above technical solution, when the switching mechanism of the air outlet assembly 100 of the present embodiment is in the first state, the switching mechanism can open the first air outlet 11 and close the second air outlet 12, so that the air is heated by the heating element 2 at the first air outlet 11 and then blown out, and the indoor temperature can be raised. When the switching mechanism is in the second state, the switching mechanism can prevent wind from flowing through the heating element 2, so that wind flows out through the second air outlet 12 and the indoor temperature is reduced. Therefore, the air outlet assembly 100 of the present embodiment does not need to move the heavy heating element 2 during use, which reduces the requirement for torque of the adjusting mechanism, and is helpful for improving the reliability of the fan and reducing the cost of the fan. Because the air outlet is used for cold air and warm air respectively, the height of each air outlet can be independently set according to the use requirement, the situation that the position of the air outlet interface of the fan is lower is avoided, and cold air is difficult to blow to the upper half of a person is avoided. In addition, the air outlet assembly 100 of the embodiment has a simple structure, is easy to manufacture, and is convenient to implement, popularize and apply.

In the present embodiment, as shown in fig. 5 and 6, the switching mechanism includes a first rotation source 31 and a shutter 32.

Preferably, in the present embodiment, the first rotation source 31 is provided on the housing 1. The baffle 32 is provided in the housing 1 and hinged to the side wall of the housing 1. The first rotation source 31 is connected to the shutter 32. The shutter 32 has a first state of blocking the first air outlet 11 and a second state of blocking the second air outlet 12. The first rotation source 31 may alternatively be a device capable of outputting rotation, such as an electric motor, an engine, a hydraulic motor, or a combination of one of them and a speed reducer, or the like. For example, in the present embodiment, the first rotation source 31 is a stepping motor.

In the present embodiment, the shutter 32 is hinged to the housing 1 by a hinge shaft 33. A first stopper 13 and a second stopper 14 are formed on a side wall of the housing 1 and one of the hinge shafts 33. An abutment 331 is formed on the other of the side wall of the housing 1 and the hinge shaft 33. When the shutter 32 is in the first state, the abutment portion 331 abuts against the first stopper portion 13. When the shutter 32 is in the second state, the abutment portion 331 abuts against the second stopper portion 14. Therefore, the abutting portion 331 can abut against the first stop portion 13 or the second stop portion 14 when the baffle 32 rotates in place, so as to position the baffle 32, and prevent the influence of inaccurate positioning of the baffle 32 on the air outlet of the air outlet assembly 100.

The angle between the first plane and the second plane is preferably set to: when the first plane is abutted with the abutting part 331 of the D-shaped column, the baffle plate 32 can expose the first air outlet 11 and shield the second air outlet 12, and when the second plane is abutted with the abutting part 331 of the D-shaped column, the baffle plate can expose the second air outlet 12 and shield the first air outlet 11. Preferably, in the present embodiment, the first plane is perpendicular to the second plane.

The first rotation source 31 may alternatively be provided inside the housing 1, or may alternatively be provided outside the housing 1. Preferably, the first rotation source 31 is located outside the housing 1 in order to secure tightness between the baffle 32 and the inner wall of the housing 1. Mounting holes 15 are formed in the side walls of the housing 1. The hinge shaft 33 passes through the mounting hole 15.

Preferably, in the present embodiment, one of the baffle plate 32 and the housing 1 is formed with a sliding protrusion 333, and the other is formed with a guide chute 16 adapted to accommodate the sliding protrusion 333. This enables the connection between the baffle 32 and the inner wall of the housing 1 by means of the sliding protrusion 333 and the guide chute 16 to support, reduces the contact area between the baffle 32 and the inner wall of the housing 1, and enables the operation of the baffle 32 to be more stable and controllable, while avoiding the problem of abrasion of the contact surface of the baffle 32 and the housing 1 due to deformation of the baffle 32. The sliding protrusion 333 is preferably, but not limited to, a needle, a cylinder, or a cube, for example, in the present embodiment, the sliding protrusion 333 is a cylinder, and the cylinder is capable of sliding to any position in the guide rail without interfering with the inner wall of the guide rail, so as to ensure that the sliding protrusion 333 can slide smoothly in the guide rail.

The guide chute 16 is optionally provided on the inner wall of only one side of the housing 1, and preferably, in the present embodiment, both ends of the baffle 32 are formed with sliding protrusions 333. Guide sliding grooves 16 are formed on both opposite side walls of the housing 1. The two guide slide rails can form double limiting on two sides of the baffle 32, so that the tightness of the connection between the baffle 32 and the first air outlet 11 and the second air outlet 12 is ensured, and the air supply effect of cold air and warm air is ensured.

Preferably, in the present embodiment, the slide protrusion 333 and the guide chute 16 are provided as follows: when the shutter 32 is in the first state, the slide protrusion 333 abuts against the first end of the guide chute 16. When the baffle 32 is in the second state, the sliding protrusion 333 abuts against the second end of the guide chute 16, which makes the edge of the guide chute 16 also play a limiting role on the baffle 32, and positioning is more reliable.

Preferably, as shown in fig. 3 and 4, in the present embodiment, the housing 1 is formed by butting the first half-shell and the second half-shell, and the baffle 32 is provided between the first half-shell and the second half-shell, which can facilitate the baffle 32 to be installed in the housing 1.

The positions of the first air outlet 11 and the second air outlet 12 can be set according to the actual use environment of the air outlet mechanism, and the second air outlet 12 is preferably arranged above the first air outlet 11. For example, in the present embodiment, the first air outlet 11 is formed at the front side of the housing 1. In the vertical direction, the second air outlet 12 is located above the first air outlet 11. This makes the position of first air outlet 11 set up lowerly, and when the switching mechanism was in the first state, the air was heated through heating element 2 and is flowed out from first air outlet 11, is close to ground, and the warm air is lighter, can rise after sending out to evenly distributed in whole room promotes indoor whole temperature.
