DETAILED DESCRIPTION

[0042] The following is combined with Figure 1 -Attached Figure 8 , further details of this application are given.

[0043] Common household appliances are usually equipped with knobs with switch and gear adjustment functions for convenient control. The household appliance knobs in the prior art are usually set with different gears. When the knob is rotated to a certain gear, it will be stuck in that gear to ensure accurate adjustment. However, this type of knob has a poor feel and will be stuck at each gear during the rotation process, making adjustment more inconvenient. It also lacks intelligence. Therefore, the embodiment of the present application provides a household appliance intelligent switch knob device, referring to Figure 1 and Figure 2The device comprises a base 1, a circuit board 2, a switch trigger assembly 3, a knob assembly 4, and a display assembly 5. The circuit board 2 and the switch trigger assembly 3 are mounted inside the base 1, the knob assembly 4 is mounted on the base 1, and the display assembly 5 is mounted inside the knob assembly 4. The switch trigger assembly 3 is connected to the bottom of the knob assembly 4, and the switch trigger assembly 3 and the display assembly 5 are electrically connected to the circuit board 2. The knob assembly 4 is used to trigger the switch trigger assembly 3, which is used to send an electrical signal to the circuit board 2 when triggered, thereby turning the household appliance on and off. The display assembly 5 is used to display information such as the current gear position and switch status.

[0044] The working principle of the embodiment of the present application is as follows: the knob assembly 4 and the switch trigger assembly 3 are contact-triggered to make the knob feel better. At the same time, the display assembly 5 is used to display the current status of the household appliance, which makes it easier for the user to confirm the current status of the household appliance in a timely manner, thereby improving the intelligence of the household appliance switch knob.

[0045] like Figure 3 、 Figure 4 and Figure 5 As shown, the knob assembly 4 of the present embodiment includes a connecting member 41, a fixed member 42, and a rotating member 43. The bottom of the fixed member 42 is connected to the base 1 via the connecting member 41. The rotating member 43 is nested outside the fixed member 42 and rotates around it. The outer ring of the fixed member 42 is provided with a number of elastic engaging blocks 421 at regular intervals, while the inner ring of the rotating member 43 is provided with a number of engaging grooves 431 at regular intervals. In practice, when the rotating member 43 rotates, the engaging blocks 421 deform and separate from the engaging grooves 431. When the rotating member 43 continues to rotate to the desired position, the engaging blocks 421 snap into the corresponding engaging grooves 431. This provides a slight damping effect during the knob's rotation. When the knob reaches the desired position, the elastic engaging blocks 421 engage the engaging grooves 431 with a "clicking" sound, indicating to the user that the desired position has been reached, effectively improving the knob's usability.

[0046] In a preferred embodiment, in order to facilitate the user to rotate the knob assembly 4, an anti-slip structure is provided on the outer ring surface of the rotating member 43.

[0047] like Figure 6As shown, the switch trigger assembly 3 of the present embodiment includes a trigger member 31 and a switch member 32. The trigger member 31 is connected to a fixing member 42, and the switch member 32 is electrically connected to the circuit board 2. The trigger member 31 includes a trigger portion and a reset portion. The trigger portion has a connection hole on the side near the fixing member 42, and a connecting rod on the side of the fixing member 42 near the trigger member 31. The connecting rod is inserted into the connection hole to connect the fixing member 42 to the trigger member 31. The trigger portion has a retaining groove 311 on the side near the switch member 32, and a contact rod 321 on the side near the trigger member 31. When the trigger member 31 is stationary, the contact rod 321 is located in the middle of the retaining groove 311. When the trigger member 31 moves, the contact rod 321 contacts either side of the retaining groove 311, causing electrical conduction between the trigger member 31 and the switch member 32. The reset portion is elastically connected to the interior of the base 1 via a reset spring 33. The reset portion is provided with two spring fixing holes 312 , and two spring fixing columns 11 are provided inside the base 1 . The two reset springs 33 are respectively fixed between the two spring fixing holes 312 and the spring fixing columns 11 .

[0048] During the specific implementation process, when the rotating part 43 rotates, since the separation of the clamping block 421 and the clamping groove 431 requires a certain displacement, it will drive the fixing part 42 to move, thereby moving the trigger part 31 connected to the fixing part 42, so that the contact rod 321 of the trigger part 31 contacts the limiting groove 311 of the switch part 32, so that the switch trigger assembly 3 is connected to the circuit board 2. When it rotates to a certain position, the clamping block 421 and the clamping groove 431 are separated, the fixing part 42 stops moving, and the reset spring 33 resets the trigger part 31 to its initial state.

[0049] like Figure 7 As shown, the display assembly 5 of the embodiment of the present application includes a light-emitting panel, a light-shielding panel, a display panel 51 and a protective panel. The light-emitting panel, the light-shielding panel, the display panel 51 and the protective panel are sequentially mounted on the fixing member 42, and the light-emitting panel is electrically connected to the circuit board 2. In the specific implementation process, the light-emitting panel emits light and then passes through the light-shielding panel and the display panel 51 so that the display assembly 5 displays the required information. The display panel 51 is protected by the protective panel to ensure the intelligence and structural stability of the switch knob. The display panel 51 may include a gear display area 511, a mode display area 512, a digital display area 513 and a switch display area 514, so that the display assembly 5 can display gear information, mode information, digital information and switch information.

[0050] The present application also provides a chef machine, referring to Figure 8 The food processor body 6 includes a household appliance intelligent switch knob device. The intelligent switch knob device 7 controls the food processor body 6, simplifying the user's operation. The display component 5 displays information so that the user can see the current status of the food processor more clearly, making it easier to use.

[0051] During specific implementation, the smart switch knob device 7 for household appliances according to an embodiment of the present application can also be provided in other household appliances to control the household appliances, such as an air fryer.

[0052] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
