DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] The adjustable cover opening and stopping device of the utility model is as follows: Figures 1 to 3 As shown, it includes a cover body 20, and the cover body 20 is provided with an outer lug 2. In other words, the outer lug 2 is extended outward relative to the cover body 20. The adjustable cover opening and stopping device of the present invention also includes a driving rod 3 for inserting into the power switch assembly 11 outside the barrel body 1 to press the switch button 111, as shown in FIG. Figure 3 As shown, the power switch assembly 11 includes a switch button 111 and a housing 112. The switch button 111 is movable up and down in the housing 112. The switch button 111 can be driven by the elastic force of the elastic member to move upward and reset. Figure 3As shown, the upper end of the driving rod 3 can be connected to the outer lug 2 in a transverse sliding manner (the "transverse" here refers to the direction roughly in the horizontal plane). Under normal use, the driving rod 3 is arranged upright. In other words, the sliding direction of the driving rod 3 is perpendicular to the axis of the driving rod 3. The upper end of the driving rod 3 is installed and connected to the outer lug 2. The driving rod 3 can be loosened from the outer lug 2 so that the driving rod 3 can be adjusted relative to the outer lug 2. In other words, the mounting connection structure between the upper end of the driving rod 3 and the outer lug 2 is a releasable mounting structure. When the mounting connection structure between the upper end of the driving rod 3 and the outer lug 2 is loosened, the sliding connection between the upper end of the driving rod 3 and the outer lug 2 takes effect. When the mounting connection structure between the upper end of the driving rod 3 and the outer lug 2 is restored (so that the driving rod 3 and the outer lug 2 are relatively fixed), the sliding connection between the upper end of the driving rod 3 and the outer lug 2 becomes invalid. For example, the mounting connection structure between the upper end portion of the driving rod 3 and the outer lug 2 can be a screw that fixes the upper end portion of the driving rod 3 relative to the outer lug 2, and the above-mentioned screw can pass through the outer lug 2 and be coaxially screwed with the driving rod 3; for another example, a screw is vertically screwed to the driving rod 3, and the end of the screw is tightly pressed against the outer lug 2 (that is, the driving rod 3 and the outer lug 2 are fixed relative to each other through friction resistance).

[0021] During the assembly and debugging of the food processing appliance, the driving rod 3 and the outer lug 2 can be loosened relative to each other. Figure 1As shown, the cover body 20 is then covered on the upper end opening of the barrel body 1 from top to bottom, and the cover body 20 is adapted and positioned to be connected with the upper end of the barrel body 1. At the same time, the drive rod 3 is adapted to be inserted into the power switch assembly 11, and the lower end of the drive rod 3 presses the switch button 111. Since in the above process, the drive rod 3 can slide relative to the outer lug 2, the rigid interference between the drive rod 3 and the power switch assembly 11 is avoided, and then three circumferentially evenly distributed lock buckles 5 are used to fasten the cover body 20 to the barrel body 1 to prevent the cover body 20 from loosening upward. Movement, that is, first assemble the cover body 20 well, and then activate the installation connection structure between the upper end of the driving rod 3 and the outer lug 2, that is, fix the driving rod 3 and the outer lug 2 relatively, so that the driving rod 3 is positioned at a suitable position relative to the outer lug 2. In other words, the position of the driving rod 3 is flexibly adapted to the actual situation of each food processing appliance, which is beneficial to the stable operation of the adjustable cover opening and stopping device of the present invention, thereby helping to improve the product quality of the food processing appliance with the adjustable cover opening and stopping device of the present invention. After long-term use, if the driving rod 3 is displaced relative to the outer lug 2 (in the horizontal plane), resulting in poor connection between the driving rod 3 and the power switch assembly 11, the customer can loosen the driving rod 3 relative to the outer lug 2 and then properly assemble the cover 20. During this process, the driving rod 3 can slide and adjust its position relative to the outer lug 2, and finally restore the driving rod 3 and the outer lug 2 to a relatively fixed installation state, so that the driving rod 3 and the outer lug 2 are restored to a well-matched state, thereby avoiding wear and tear on the driving rod 3 and the power switch assembly 11, which is beneficial to extending the life of the food processing appliance and improving its durability. Figure 1 As shown, the cover body 20 can be circular, that is, when the cover body 20 is installed, the cover body 20 can be rotated and adjusted relative to the barrel body 1, so that the sliding direction of the drive rod 3 relative to the outer lug 2 can be in the radial direction of the cover body 20.

[0022] Furthermore, if Figures 2 to 5As shown, the outer lug 2 is provided with a groove shell 24, and the groove shell 24 is formed with a slide groove 241. A slider 4 is provided in the slide groove 241. The slider 4 can slide in the slide groove 241, and the slide groove 241 circumferentially positions the slider 4, that is, the slider 4 cannot rotate. A positioning long hole 242 is formed at the bottom of the slide groove 241. The extending direction of the positioning long hole 242 is parallel to the sliding direction of the slider 4. A screw portion 321 is formed at the upper end of the drive rod 3. The screw portion 321 passes through the positioning long hole 242 from bottom to top, and the screw portion 321 is screwed to the slider 4. The edge of the positioning long hole 242 is relatively fixedly clamped on the drive rod 3 by the slider 4, thereby fixing the drive rod 3 and the outer lug 2 relatively. Among them, the slider 4 can use an external hexagonal nut. The opposite sides of the external hexagonal nut are respectively against the inner wall of the slide groove 241, thereby preventing the external hexagonal nut from rotating in the slide groove 241. Therefore, by rotating the drive rod 3, the drive rod 3 can clamp the edge of the adjustment slot 242. When the drive rod 3 needs to be adjusted, the drive rod 3 is rotated in the opposite direction to loosen the drive rod 3 and the outer lug 2. Then, the drive rod 3 can be pushed by hand to slide and adjust the screw portion 321 and the slider 4 in the slide groove 241. Or, when the drive rod 3 is inserted into the power switch assembly 11, the power switch assembly 11 can push the drive rod 3 relative to cause the drive rod 3 to slide and adjust slightly. After the adjustment is completed, the drive rod 3 and the outer lug 2 can be restored to a relatively fixed state by rotating the drive rod 3. The mounting connection structure of the upper end of the drive rod 3 and the outer lug 2 is simple and easy to manufacture, and it is convenient to switch the drive rod 3 and the outer lug 2 between a relatively fixed state and a relatively loose state.

[0023] Furthermore, if Figures 2 to 4 As shown, the outer lug 2 includes an ear plate body 21, and the groove shell 24 is fixed to the lower side of the ear plate body 21 by welding. The ear plate body 21 is located on the upper side of the screw portion 321 and the slider 4, that is, the ear plate body 21 covers the opening of the slide groove 241, as shown in FIG. Figure 1 and Figure 3 As shown, the screw portion 321 and the slider 4 are prevented from being exposed on the ear plate body 21, and human hands are prevented from touching the screw portion 321 and the slider 4. It is also beneficial for the outer lug 2 to have a simple appearance, and a hole structure can be formed on the ear plate body 21 for the slider 4 to be inserted into the slide groove 241.

[0024] Furthermore, if Figure 1 and Figure 3As shown, the ear plate body 21 is formed with a rib 211. The rib 211 extends in the direction in which the outer lug 2 extends relative to the cover body 20. In other words, when the outer lug 2 extends radially from the cover body 20, the rib 211 extends in a direction parallel to the radial direction of the cover body 20. The rib 211 is formed by punching a recess upward on the underside of the ear plate body 21. The provision of the rib 211 provides a partially three-dimensional structure to the ear plate body 21, thereby increasing the structural rigidity of the ear plate body 21 and preventing the drive rod 3 from skewing, thereby facilitating a good connection between the drive rod 3 and the power switch assembly 11.

[0025] Furthermore, if Figure 2 As shown, the outer lug 2 is formed with a side plate portion 22, and the upper end of the side plate portion 22 is connected to the edge of the ear plate body 21 as a whole, that is, the side plate portion 22 is bent downward relative to the ear plate body 21, thereby facilitating the increase of the structural strength and rigidity of the outer lug 2. Figure 1 and Figure 2 As shown, the two ends of the edge plate portion 22 are respectively abutted against the outer side wall of the cover body 20 (that is, the outer cylindrical surface of the cover body 20) that is fixedly connected (can be welded), and one end of the ear plate body 21 is abutted against the top of the cover body 20 that is fixedly connected (can be welded). That is to say, one end of the ear plate body 21 is overlapped on the upper side of the cover body 20, so that the two ends of the outer lug 2 (in the circumferential direction of the cover body 20) wrap the upper corners of the cover body 20, thereby increasing the connection strength between the outer lug 2 and the cover body 20, and combined with the supporting effect of the edge plate portion 22, further preventing the outer lug 2 from bending downward or upward relative to the cover body 20.

[0026] Furthermore, if Figure 4 As shown, the lower end of the driving rod 3 is formed with a trigger pin 31 for contacting the switch button 111, and the driving rod 3 is formed with a handle 32 between the trigger pin 31 and the screw portion 321. The outer diameter of the handle 32 is larger than the outer diameter of the trigger pin 31. Figure 3 and Figure 4 As shown, the edge of the adjustment long hole 242 is sandwiched between the upper end surface of the handle 32 and the bottom of the slider 4. Therefore, by providing the handle 32, it is beneficial to increase the strength and rigidity of the driving rod 3 and avoid bending and deformation of the driving rod 3. Figure 3 As shown, the lower end of the handle 32 can be formed with an outer conical surface. When the trigger pin 31 of the drive rod 3 presses the switch button 111, the above-mentioned outer conical surface cooperates with the inner conical surface of the shell 112 to prevent liquid from flowing into the shell 112.

[0027] like Figure 6As shown, the barrel 1 of some soybean milk makers is covered with an insulating cylindrical shell 10. In other words, this type of soybean milk maker has a double-shell structure, so that the switch mounting box 110 is arranged further outward (relative to the central axis of the barrel 1). The power switch assembly 11 is installed in the switch mounting box 110, so the driving rod 3 can slide outward accordingly to adapt to the position of the power switch assembly 11. Figure 1 As shown, the switch mounting box 110 is connected to a wire groove 1101, and the wire connected to the power switch assembly 11 is led downward through the wire groove 1101 to the base of the soymilk machine, as shown in FIG. Figure 6 As shown, when the heat insulating shell 10 is provided, the heat insulating shell 10 can cover the wire groove 1101 .
