Therefore, through the extension and change design of the support member 34, the structural strength of the actuating unit 30 is increased, so that the actuating device 100 of the present invention can be more widely used in various valve products.

[0045] In this embodiment, the actuation area 40 has a port 41 and an actuation element 42. The actuation element 42 is controlled by the first driving unit 32 or the second driving unit 33, thereby controlling the port 41 to be opened or closed.

[0050] The following introduces another form of multi-directional control valve device 100a. The same or similar elements as the previous embodiment are represented by the same or similar symbols, and no further description is given. The following only describes the main differences between the different embodiments.

[0051] Figure 6 2 is a cross-sectional schematic diagram of a multi-way control valve device according to a second embodiment of the present invention. Figure 7 yes Figure 6 A three-dimensional diagram of a multi-directional control valve device. Figure 6 and Figure 7 The main difference between the multi-directional control valve device 100a of this embodiment and the multi-directional control valve device 100 of the previous embodiment is that in this embodiment, the first driving part 32 is only provided with the operating area 40, and the first driving part 32 of the actuating unit 30 controls the opening or closing of a single port 41, while the second driving part 33 controls the opening or closing of another port 41. Therefore, in this embodiment, through the design concept of the actuating unit 30 and the fixing part 31, by fine-tuning the setting position of the fixing part 31 on the actuating unit 30, the first driving part 32 and the second driving part 33 can achieve the same or different actuation capabilities.

[0052] See also Figure 6 and Figure 7In this embodiment, the internal space 10 of the housing 1 provides gas or fluid for conduction to the internal space 10 via the input source 20. More specifically, a check valve can be connected to the input channel inside the input source 20. The correct conduction direction of the gas or fluid can be effectively controlled by setting the check valve to avoid backflow. The check valve can also be set on the housing 1 or inside the port 41. The setting position and number of the check valve are not limited to this. In addition, in this embodiment, the input source 20 can also be connected to a filter element. The setting of the filter element can enhance the filtering efficiency of the gas or fluid flowing through the channel. The filter element can also be set on the housing 1 or inside the port 41. The setting position and number of the filter element are not limited to this.

[0053] In summary, the multi-directional control valve device of the present invention is provided with an actuating unit in the internal space of the housing and at least one actuating area. Due to the lever movement principle of the actuating area, the gas or fluid provided by the input source is effectively and accurately transmitted to the corresponding port, thereby improving the driving efficiency of the multi-directional control valve.
