The functional unit 206 is used to implement a designated function (such as a purification function, a heating function, a cooling function, a dehumidification function or a dust collection function, etc.).

As shown in FIG. 9, the functional unit 206 can be arranged before the air intake structure 210, and can process the air before entering the air intake structure 210 (such as purification treatment, heating treatment, refrigeration treatment, dehumidification treatment or dust suction treatment, etc.) ), so that the air flow generating unit 202 introduces the processed air into the air chamber space 208, and discharges the processed air from the air outlet structure 209.

Please also refer to FIG. 10, which is a flowchart of the method for adjusting the volume of the air chamber according to the first embodiment of the creation. The method of adjusting the volume of the air chamber in each embodiment of the present invention can be implemented by any air flow generating device shown in FIGS. 2A to 9.

The method for adjusting the volume of the air chamber in this embodiment includes the following steps.

Step S10: The control unit 200 detects the rotation speed of the airflow generating unit 202 through the airflow control module 30, such as obtaining the operating parameters of the airflow generating unit 202.

Step S11: The control unit 200 detects through the airflow control module 30 whether the rotation speed of the airflow generating unit 202 changes, such as a change in operating parameters.

If the rotation speed of the air flow generating unit 202 does not change, there is no need to adjust the volume of the air chamber space 208 accordingly. The control unit 200 executes step S10 again to continue the detection.

If the rotation speed of the air flow generating unit 202 changes, the volume of the air chamber space 208 needs to be adjusted accordingly, and the control unit 200 executes step S12: the control unit 200 obtains through the adjustment control module 31 this time that the control adjustment unit 201 needs to move the air outlet structure 201 (And/or the moving distance of the air inlet structure 210).

In an embodiment, the different rotation speeds of the airflow generating unit 202 are respectively corresponding to different moving distances (such as 1 cm, 3 cm, or 5 cm) in advance, and the control unit 200 obtains the moving distance corresponding to the current rotation speed of the airflow generating unit 202. .

In one embodiment, the storage unit 204 records the correspondence between multiple rotation speed settings (such as the aforementioned operating parameters) of the airflow generating unit 202 and multiple movement distances of the adjustment unit 201 (such as stored in the form of a look-up table). The control unit 200 can obtain the aforementioned movement distance through the following steps S20-S21.

Step S20: The control unit 200 reads the corresponding relationship from the storage unit 204 through the adjustment control module 31.

Step S21: The control unit 200 selects a set of moving distances (for example, by querying a lookup table) by adjusting the control module 31 according to the obtained correspondence relationship and the rotation speed setting currently used by the air flow generating unit 202.

Step S13: The control unit 200 controls the adjustment unit 201 through the adjustment control module 31 to adjust the wind in and out distance based on the selected movement distance.

In one embodiment, the control unit 200 increases the air inlet and outlet distances when the air flow generating unit 202 increases the speed, so as to increase the volume of the air chamber space 208 and reduce the noise of the air flow. In addition, the control unit 200 reduces the air inlet and outlet distance when the air flow generating unit 202 reduces the rotation speed, so as to reduce the volume of the air chamber space 208 and increase the pressure and speed of the air flow.

In this way, this creation can increase the wind intensity or reduce the airflow noise according to user needs.

Please also refer to FIG. 11, which is a flow chart of obtaining condition movement in the second embodiment of this creation. This embodiment further provides a conditional movement function, which is to continuously adjust the distance of the wind in and out until the preset critical condition is met, thereby providing a better user experience. Specifically, the method for adjusting the volume of the air chamber of this embodiment further includes the following steps.

Step S30: The control unit 200 continuously obtains the reading of the sensing unit 203.

In one embodiment, the present invention provides a performance priority function, which can adjust the volume of the air chamber space 208 based on the current rotation speed of the air flow generating unit 202 to provide the current best ventilation performance. Specifically, the sensing unit 203 is an anemometer or a barometer, and the control unit 200 can continuously obtain the wind speed reading or air pressure reading of the airflow of the wind structure 209 from the sensing unit 203 through the performance priority module 33.

In one embodiment, the present creation is to provide a noise reduction priority function, which can adjust the volume of the air chamber space 208 based on the current rotation speed of the air flow generating unit 202 to minimize the noise generated by the air flow. Specifically, the sensing unit 203 is a decibel meter, and the control unit 200 can continuously obtain the noise reading of the airflow of the wind structure 209 from the sensing unit 203 through the noise reduction priority module 34.

Step S31: The control unit 200 controls the adjustment unit 201 to start moving the air inlet structure 210 and/or the air outlet structure 209 through the adjustment control module 31 to start increasing or decreasing the aforementioned air inlet and outlet distances.

Step S32: The control unit 200 determines whether the preset critical condition is satisfied. Specifically, as the volume of the air chamber 205 increases or decreases, the reading of the sensing unit 203 also changes accordingly. The control unit 200 determines whether the current reading of the sensing unit 203 meets the aforementioned critical condition (such as a preset reading).

In one embodiment, when the performance priority function is provided, the control unit 200 can determine through the performance priority module 33 whether the current wind speed reading meets the wind speed critical condition (such as higher than the preset wind speed value), or whether the current air pressure reading meets Critical air pressure conditions (such as higher than the preset air pressure). The aforementioned preset wind speed value or preset air pressure value may be a better performance value that the airflow generating unit 202 can generate based on the current rotation speed.

In one embodiment, when the noise reduction priority function is provided, the control unit 200 can determine through the noise reduction priority module 34 whether the current noise reading meets the noise critical condition (such as lower than the preset noise value). The aforementioned preset noise value may be a general noise value or a lower noise value that the airflow generating unit 202 can generate based on the current rotation speed.

Step S33: The control unit 200 controls the adjustment unit 201 through the adjustment control module 31 to stop moving the air inlet structure 210 and/or the air outlet structure 209 to stop adjusting the aforementioned air inlet and outlet distances.

In this way, this creation can provide a better user experience.

Please also refer to FIG. 12, which is a flowchart of anomaly detection according to the third embodiment of the creation. This embodiment further provides an abnormality detection function, which can detect whether an abnormal condition occurs during the operation of the adjustment unit 201, so as to avoid damage to the air flow generating device (for example, a foreign object jams the adjustment unit 201 and causes the adjustment unit 201 to malfunction). Specifically, the method for adjusting the volume of the air chamber of this embodiment further includes the following steps.

Step S40: The control unit 200 starts to control the adjustment unit 201 to adjust the air inlet and outlet distances through the abnormality detection module 35.

Step S41: The control unit 200 continuously detects whether any abnormal situation occurs during the adjustment process through the abnormality detection module 35, such as an abnormal increase in the current of the adjustment unit 201 (indicating that a foreign object may be stuck in the adjustment unit 201), the sensing unit The reading of 203 does not change with the distance of the air entering and exiting, or the sensing unit 203 (such as a foreign object detector) detects an abnormal condition (such as a foreign object in the air chamber space 208), etc., and so on, it is not limited.

If no abnormality is detected, the control unit 200 executes step S41 again to continue the detection until the adjustment unit 201 finishes adjusting the air inlet and outlet distances.

If any abnormality is detected, the control unit 200 executes step S42: the control unit 200 controls the adjustment unit 201 through the abnormality detection module 35 to stop adjusting the air inlet and outlet distances.

In one embodiment, after stopping the adjustment of the air inlet and outlet distances, the control unit 200 can control the adjustment unit 201 through the abnormality detection module 35 to adjust the air inlet and outlet distances in the opposite direction, such as returning the air inlet and outlet distances to the state before adjustment.

In this way, the present creation can effectively detect abnormal conditions and avoid damage caused by the continuous operation of the airflow generating device in the abnormal conditions.

The above is only a preferred specific example of this creation, and it does not limit the patent scope of this creation. Therefore, all equivalent changes made by using this creation content are included in the scope of this creation for the same reason. Bright.
