For the direction word appearing in the utility model, it is to better explain the characteristics of features and the relationship between features, it should be understood that when the display direction of the utility model changes, the direction of the characteristics of features and the relationship between features also changes accordingly, therefore, the direction word does not constitute the absolute limitation of the characteristics of features and the relationship between features in space, and only plays a relative limiting role.

[0028] The utility model provides a kind of top knob press switch structure, as shown in Figures 1 to 6 It includes body 1, top cover 2, switch connecting piece 3 and gear wave positioning ring 4;Body 1 is provided with mounting seat 11, top cover 2 is circumferentially rotatable and axially slidably connected in mounting seat 11, mounting seat 11 is provided with selection start-stop module 12, selection start-stop module 12 is provided with switch column 13, switch column 13 can be rotated and pressed down to trigger the selection of selection start-stop module 12 and the starting function of kinetic energy;Top cover 2 is provided with embedded groove 21, switch connecting piece 3 is set in switch column 13 and embedded in embedded groove 21, and gear wave positioning ring 4 is circumferentially fixedly connected in top cover 2;

[0029] When rotating top cover 2, gear wave positioning ring 4, switch connecting piece 3 and switch column 13 rotate with top cover 2;When pressing top cover 2, top cover 2 drives switch connecting piece 3 and switch column 13 to move axially.

[0030] Based on the above structure, the rotation of the top cover 2 drives the rotation of the gear wave positioning ring 4, the switch connecting piece 3 and the switch column 13 to trigger the gear selection function of the gear selection start-stop module 12, and further pressing the top cover 2 makes the switch column 13 trigger the start function of the gear selection start-stop module 12, so that the meat grinder can work according to the required gear, avoiding the problem of accidental touch caused by multiple buttons, greatly reducing the risk of accidental touch, and making the operation more intuitive and accurate.

[0031] In the embodiment, the mounting seat 11 is provided with a fixed connecting piece 5, the fixed connecting piece 5 is provided with a anti-falling snap ring 51, the top cover 2 is provided with an anti-falling snap hook 22, and the top cover 2 is axially slidably connected to the fixed connecting piece 5 and the anti-falling snap hook 22 can be limited in the anti-falling snap ring 51. Through the cooperation of the anti-falling snap ring 51 and the anti-falling snap hook 22, the stability and reliability of the top cover 2 during sliding are ensured, and the falling or misplacement of the top cover 2 is prevented.

[0032] In the embodiment, the mounting seat 11 is provided with a elastic positioning piece 6, the gear wave positioning ring 4 is provided with a plurality of pairs of positioning valleys 41 and positioning peaks 42 forming a continuous wave shape at the end face facing the mounting seat 11, and the elastic positioning piece 6 is located at a position capable of abutting the positioning valleys 41 and the positioning peaks 42 in turn. When the gear wave positioning ring 4 rotates, the elastic positioning piece 6 can drive the gear wave positioning ring 4 to rotate until the elastic positioning piece 6 abuts the positioning valley 41 when the elastic positioning piece 6 abuts the positioning peak 42. During the rotation of the gear wave positioning ring 4, the elastic positioning piece 6 can abut the gear wave positioning ring 4 by means of its own elastic force, so that the gear wave positioning ring 4 is rotated to the position where the elastic positioning piece 6 abuts the positioning valley 41, thereby ensuring that the top cover 2 is rotated to the accurate position corresponding to each gear. At the same time, the elastic deformation and feedback mechanism of the elastic positioning piece 6 provides clear tactile feedback for the user, which helps the user to better master the rotation force and timing, and improves the comfort and accuracy of operation.

When the top cover 2 is pressed, the anti-rotation snap block 24 can be snapped into the anti-rotation snap groove 53. When the top cover 2 is pressed, the anti-rotation snap block 24 will accurately snap into the anti-rotation snap groove 53, thereby limiting the circumferential rotation of the top cover 2 and preventing unnecessary rotation of the top cover 2 when it is pressed, which can cause incorrect gear selection.

[0034] In the embodiment, the gear wave positioning ring 4 is provided with a fixed snap block 43, and the top cover 2 is provided with a fixed snap groove 23. The fixed snap block 43 is snapped into the fixed snap groove 23 to fix the gear wave positioning ring 4 to the top cover 2. Through the cooperation of the fixed snap block 43 and the fixed snap groove 23, the gear wave positioning ring 4 is fixed to the top cover 2, thereby realizing the rotation of the gear wave positioning ring 4 by rotating the top cover 2 to select the corresponding gear.

[0035] In the embodiment, the mounting seat 11 is provided with a rotating gap 14, and the top cover 2 is provided with a rotating limiting block 25 which is circumferentially rotated in the rotating gap 14. The rotating range of the top cover 2 is limited by the rotating limiting block 25, which prevents the top cover 2 from rotating to an angle without gear selection, and helps to maintain the overall stability and reliability of the device.

[0036] In the embodiment, the upper surface of the top cover 2 is provided with a function gear mark. The function gear mark enables the user to intuitively understand the current selected gear and the adjustable range, which helps to improve the user's operation experience and satisfaction.

[0037] In summary, the top knob press switch structure can solve the problem that the top of the meat grinder is provided with multiple key function gears in the prior art, and the adjacent keys are easily mispressed.

[0038] In the case of no conflict, the above-mentioned embodiments and features in the embodiments can be combined with each other.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
