Wherein, when a plurality of blade sets are disposed, the following conditions are required, in which the blades 2 are the same in the circumferential direction of the cross-flow wind wheel 1 in the same blade group, and in at least one of the plurality of blade groups The blades are opposite to the circumferential direction of the cross-flow wind turbines with the other one or more of the blade sets. (The upper blade group in the connection mode in which the blades in the adjacent blade group are opposite in the circumferential direction of the cross flow wind wheel is defined as "forward blade", and the next blade group is defined as "reverse blade"). When the cross-flow wind wheel 1 is driven by the power element, the forward blade is blown when the power element rotates forward, and vice versa, the reverse blade air supply is realized.

However, the present cross-flow fan can achieve the beneficial effects of the above-described cross-flow wind wheel 1, and will not be described herein.

Among them, there are many ways in which the rotating shaft is fixedly connected to the output shaft of the motor. The two fixing methods are specifically described below.

For example, the shaft of the shaft and the output shaft of the motor are connected via a coupling. For example, a first through hole penetrating through the output shaft of the power supply machine and a threaded hole through which the screw is threaded are opened on the rotating shaft, and the first through hole and the threaded hole are perpendicular and penetrated, and are perpendicular to the axis on the output shaft of the motor. A second through hole corresponding to the threaded hole is disposed, and the screw sequentially passes through the threaded hole and the second through hole to fix the motor output shaft and the rotating shaft.

Embodiment 3

The third embodiment is a blower device, as shown in FIG. 3 to FIG. 5, comprising a casing 6 and the above-mentioned cross-flow fan; the casing 6 is provided with a relatively closed cavity 61, and the casing 6 has at least one The air inlet 62 and the at least one air outlet 63, the air inlet 62 and the air outlet 63 are both connected to the cavity 61; the cross flow fan is at least one and is fixed in the cavity 61; the airflow to be output is passed through the cross flow fan, and The air outlet 63 is output.

It should be noted that in order to increase the amount of intake air and the amount of airflow, the cavity 61 is disposed to be relatively sealed. Relatively sealed means that the air inlet 61 is provided with an air inlet 62 and an air outlet 63, and cannot be regarded as completely sealed.

In the present embodiment, according to the structure of the casing 6, two cross-flow fans are symmetrically disposed with the center line of the entire air blowing device as an axis. A plurality of cross flow fans can be disposed inside the casing 6 by changing the shape or internal configuration of the casing 6.

Specifically, the structure of the housing 6 in this embodiment is shown in FIG. 5 and FIG. 6. The housing 6 includes an intermediate housing 64 that is open at opposite ends and has a hollow annular shape, and is spliced and opposed to the intermediate housing 64. The left end housing 65 and the right end housing 66, the intermediate housing 64, the left end housing 65 and the right end housing 66 form a relatively sealed cavity 61; the left end housing 65 is The left side edge of the intermediate casing 64 is formed to extend outwardly, and the opening is gradually enlarged outwardly; the right end housing 66 is formed to extend outward from the right edge of the intermediate casing 64, and the opening is gradually enlarged outward; An air inlet 62 is disposed on the left end housing 65, and an air outlet 63 is disposed on the right end housing 66.

Take the air blowing device in this embodiment as an example.

It should be noted that when the motor rotates in the forward direction, the wind is blown by the forward blades, and the working airflow is sent from the air inlet 62 through the cross-flow fan and then from the air outlet 63. When the motor rotates in the reverse direction, the reverse air blows the air, and the working air flow is sent from the air outlet 63 through the cross flow fan and then from the air inlet 62. Therefore, the air inlet 62 here is not absolutely capable of only entering the air, that is, the air outlet 63 is not absolute, and only the wind can be realized. When the working state of the motor is changed, the functions of the air inlet 62 and the air outlet 63 also occur. Change accordingly.

In addition, the two ends of the cross flow wind wheel 1 may be provided with a rotating shaft, and the cross flow wind wheel 1 is connected to the support member through the bearing seat. The fixed form of the cross-flow wind wheel 1 is not limited to this manner as long as the normal operation of the cross-flow wind wheel 1 in the casing 6 can be achieved.

In this embodiment, a heating device is fixed in the cavity 61; the heating device is located between the cross flow fan and the air inlet 62; or the heating device is located between the cross flow fan and the air outlet 63.

When the resistance is received, the direction of rotation is automatically changed. When the swing head is placed at the set position, it will be blocked and synchronized. The motor is rotated, thus forming a reciprocating swing of the housing 6.

In this embodiment, a humidifying device may be disposed in the casing 6, and the wind with water mist can be sent. The humidifying device is fixed by the above-mentioned support member, and the humidifying device can also be directly fixed to the inner middle case 641, the left end case 65 or the right end case 66.
