Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0023] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0024] In one embodiment of the present invention, as shown in Figures 1 and 2, a knob-type hand controller is provided, including a hand controller body 1. A knob 11, a reset button 12, a USB port 13, and a microphone 14 are provided on the surface of the hand controller body 1. The knob 11 is connected to the hand controller body 1 for vertical rotation. A main control board 2 and at least one encoder 21 mounted on the main control board 2 are provided within the hand controller body 1. At least one rotating wheel 3 extends downward from the knob 11, and the rotating wheel 3 engages with the output shaft of the encoder 21.

[0025] In another embodiment of the present invention, as shown in Figure 3, the hand controller body 1 is equipped with at least two encoders 21. The output shaft of each encoder 21 is equipped with a gear 22, and each gear 22 has a different height. Specifically, the knob 11 can be configured to move up and down and rotate relative to the surface of the hand controller body 1. The up and down movement of the knob 11 can switch the rotating wheel 3 to engage with different gears 22, achieving rotation of different encoders 21 and realizing more operational modes.

[0026] Furthermore, the rotating wheel 3 and the knob 11 are coaxially arranged, and toothed rings are provided on both the inner and outer sides of the rotating wheel 3 to mesh with the gear 22. Specifically, the knob 11 can be directly rotated to cause the toothed ring on the inner side of the rotating wheel 3 to mesh with the gear 22 of one encoder 21. When the knob 11 switches modes, pressing the knob 11 downward causes the toothed ring on the outer side of the rotating wheel 3 to mesh with the gear 22 of another encoder 21, thereby switching modes.

[0027] In two embodiments of the present invention, as shown in Figures 1 to 3, the reset button 12 includes a keycap 121 and a key shaft 122. The key shaft 122 is electrically connected to the main control board 2, and the keycap 121 is used to drive the key shaft 122. Specifically, when resetting, pressing the keycap 121 drives the key shaft 122 to input a reset signal to the main control board 2, which transmits the signal to a specific actuator within the furniture to execute the reset.

[0028] Furthermore, the main control board 2 is equipped with a voice module 23, which is connected to the microphone 14 via a connecting cable. The surface of the hand controller body 1 is provided with a sound receiving hole 15. Specifically, when the user uses voice control, they speak a wake-up voice and then a function command voice. After being processed by the voice module 23, the main control board 2 executes the command to the specific execution components of the home.

[0029] Furthermore, the main control board 2 is further provided with an input module 24 , and the input module 24 is connected to the USB port 13 via a connecting line.

[0030] Working principle: When in use, control instructions are input through the knob 11 and microphone 14. The lumbar support, leg support and arm support of the furniture are specific execution components, and the execution components are equipped with adjustment motors. The instructions are transmitted to the specific execution components in the furniture through the main control board 2 to achieve the control effect of the furniture. The reset instruction is input through the reset button 12, and the instruction is transmitted to the specific execution component in the furniture through the main control board 2 to perform reset. The user's smartphone can be connected through the USB port 13; when using the knob 11 for control, the control effect of the furniture can be achieved by rotating the knob 11 to make the wheel 3 drive the encoder 21 to rotate. When the knob 11 is rotated slowly, the adjustment motor of the specific execution component in the furniture can fine-tune the angle of the specific execution component; when the knob 11 is rotated quickly, the adjustment motor of the specific execution component in the furniture will continue to move. When adjusted to the appropriate angle, short press the reset button 12 to input a stop instruction to the adjustment motor; when resetting, the adjustment motor can be reset by long pressing the reset button 12 for three seconds.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
