Description

TECHNICAL FIELD

BACKGROUND OF THE INVENTION The invention relates to the field of household appliances, in particular to cans of several sizes.

TECHNICAL LEVEL

Conventional can openers with knives are described, for example, in US1641054 (A), CN106882750 (A), CN204894005 (U) and CN206590857 (U). Because the blades of these openers often protrude outwards, people can get scratched if they are misused by consumers or used by children as a toy. In addition, there are different types of cans of different heights and capacities in everyday life, so universal cans openers may not apply to all cans. It is required that when opening the tin, the top of the tin is cut without leaving the rib. The can thus opened will endanger people after it is opened.

The closest technically possible can opener is described in CN106882750 (A), which has a housing having upper and lower handles, wherein the stainless steel front of the upper handle bar has a flat concave housing with a formed groove. The groove in the flat concave body of the upper handle front has a stainless steel bar body at the front of the lower handle. The upper handle has a riveted hole in the flat concave body, the corresponding rivet hole in the lower handle in a stainless steel front. The front of the upper handle is connected to the front of the lower handle by a rivet. The front of the flat concave body made of stainless steel at the front of the upper head and the front of the flat body of stainless steel at the front of the lower handle form a cutting device having a pointed head with two blades. The inside of the stainless steel bar at the front of the upper handle and the inside of the stainless steel body at the front of the lower handle have a separate convex head with an elastic spring between the convex ends.

Using a can opener according to CN 106882750 (A), a two-blade pointed tip is inserted into the can and the can sealing cap can be gradually cut by opening and closing the pointed tip. In addition, the post-cutting edges can easily scratch the hand and the pointed head is also exposed from the outside, which can be considered a security threat. Therefore, it is necessary to create a multi-sized can opener that can hide the knives and leave no edge bend after use.

Hereafter, the applicant, referring to the appended FIG. Figures 1-4 and the above description of the design of the claimed multiple size can opener provide a detailed description of its use.

In the initial state, the second permanent magnet 32 repels the first permanent magnet 31. The first permanent magnet 31 then attracts a magnetically conductive metal plate 11. The bevelled block 29 is disengaged from the saw teeth 14.

When the can opening operation is to be performed, after the can is inserted into the symmetrically curved blocks 59, the curved blocks 59, pressed by the first springs 18, compress the can, the friction wheels 57 press the sides of the can and the can is pressed against the sliding plate 24. 39, the switch 39 activates the drive motor 41.

When the button 34 is depressed, the long bar 33 slides down and the bar 33 pushes the second permanent magnet 32 to the first permanent magnet 31, thereby increasing the repulsive force. The first permanent magnet 31 pushes the second slider 30 downward, the knife 25 moves downward, reaching the top of the can and piercing it. As the second slider 30 continues to slide down, the tin presses the ring 60, the ring 60 pushes the third slider 27 to depress the hydraulic tubes 28. The hydraulic tubes 28 push the slant block 29 to engage the saw teeth 14 so that the second slider 30 cannot move further down , and the blades 25 would no longer intervene inside the can.

The drive motor 41 is then actuated which rotates the fourth belt pulley 42 and the fourth pulley 42 rotates the third belt pulley 45 through the second belt 44. The third belt pulley 45 turns the fourth conical gears 20 and the fourth conical gears 20 rotates the third gears 20. conical pulleys 53 rotate first conical pulleys 51, first conical pulleys 51 rotate second belt pulleys 48, second belt pulleys 48 rotate first belt pulleys 56 through first belts 49. The first belt pulleys 56 rotate friction wheels 57. The rotating can is matched to the knife 25 to open it by turning the can.

The foregoing is only a specific embodiment of the present invention, but is not intended to limit the scope of the present invention, and any changes that do not require creative effort are possible and are therefore within the scope of the invention.
