Description

Technical Field

[0001] The invention relates to the technical field of bottle openers, in particular to an automatic cork-removing bottle opener. Background Art

[0002] When opening the aluminum seal of a wine bottle, such as the bottle cap of Moutai, most people use an awl or tweezers to remove the aluminum seal. Since the tools are not professional, there is a safety hazard of accidentally injuring fingers, and the efficiency is not high. Alternatively, a blade is used to manually ring-cut the aluminum seal cap to cut the aluminum seal away from the bottle mouth. This manual ring-cutting method is difficult to control, relatively dangerous, extremely inconvenient to operate, and cannot guarantee the safety of the ring cutting.

[0003] The existing electric bottle opener drives the cutter to perform circular cutting on the bottle mouth through a motor. When rotating and cutting the bottle mouth, the cutter needs to be closely abutted against the bottle mouth to ensure smooth rotary cutting. However, in the actual cutting process, the cutter not only needs to elastically avoid the bottle mouth entering the bottle opener, but also needs to be tightly pressed and abutted after the bottle mouth enters. Pressing the cutter only by an elastic member makes the abutment force between the cutter and the bottle mouth relatively small, making it difficult to effectively circularly cut the bottle mouth, affecting the efficiency of opening the bottle. Moreover, after the existing bottle opener cuts the bottle mouth, the cut bottle cap is generally removed manually, which is extremely inconvenient, and the cutter and bottle cap can easily cause damage to the hands. Summary of the invention

[0004] The invention discloses an automatic cork-removing bottle opener, aiming to improve the problem of inconvenient cork-removing of the bottle opener.

[0005] The present invention adopts the following scheme:

[0006] An automatic cork-removing bottle opener, comprising:

[0007] Upper pedestal;

[0008] A rotating seat is rotatably disposed below the upper base and has a receiving cavity with a bottom opening, wherein the receiving cavity includes an upper cavity and a lower cavity that are interconnected;

[0009] A driving mechanism, disposed in the upper base, for driving the rotating base to rotate;

[0010] A limiting shell is sleeved outside the rotating seat and can move up and down relative to the rotating seat, and has a first force-applying component that enables the limiting shell to move downward;

[0011] The plug assembly comprises a plug body slidably disposed in the accommodating cavity and a second force-applying member abutting between the plug body and the top wall of the upper chamber. When the plug body is squeezed by the bottle mouth to be cut and slides up from the lower chamber to the upper chamber, it changes from an initial state to a working state.

[0012] The cutting mechanism is arranged between the lower chamber and the inner wall of the limiting shell, and comprises a swing arm hinged to the rotating seat and a torsion component for swinging the swing arm outward, wherein one side of the swing arm is provided with a cutting portion extending toward the accommodating chamber, and the other side is provided with a pressing inclined surface protruding toward the limiting shell;

[0013] A lifting mechanism is connected to the limit shell, and is used to lift the limit shell upward after the bottle mouth is withdrawn, so as to change from the working state to the initial state, and the plug body rebounds to the lower chamber to automatically withdraw the plug;

[0014] In the initial state, the plug body and the swing arm are in abutment with each other to limit the limit housing to the upper position of the rotating seat;

[0015] When changing from the initial state to the working state, the plug body moves up to the upper chamber, releasing the limit shell, so that the limit shell presses the pressing slope downward, and the swing arm swings inward until it partially enters the lower chamber to limit the downward movement of the plug body.

[0016] As a further improvement, the first force-applying component is a compression spring, the upper end surface of the compression spring abuts against the rotating seat, and the lower end surface abuts against the lower end position of the limiting shell, and the downward pressing thrust of the compression spring is greater than the outward swinging force of the torsion component.

[0017] As a further improvement, the driving mechanism drives the rotating seat to rotate in the forward direction to cut the bottle mouth, and drives the lifting mechanism in the reverse direction to drive the limiting shell back to the upper position of the rotating seat.

[0018] As a further improvement, the lifting mechanism includes a lifting plate extending upward along the limiting shell to one side of the upper base, a shell rotatably mounted on the outside of the upper base, a guide column fixed on the shell, and a guide member arranged on the upper base; the guide member provides an upward guiding path for the guide column, the lifting plate is provided with a vertically arranged guide channel, the guide column is movably embedded in the guide channel, and the limiting shell rotates to drive the guide column to move along the guide path, thereby realizing the lifting of the limiting shell.

[0019] As a further improvement, in the working state, the guide column abuts against the upper part of the guide channel, and the driving mechanism reverses to drive the guide column to move, so as to lift the lifting plate.

[0020] As a further improvement, the guide member is a guide slope arranged in a ring on the outer wall of the upper base, and the guide slope has a guide path arranged spirally upward; there are multiple guide slopes, and they are evenly spaced; the driving mechanism is reversed to cause the guide column to spirally rise along the guide slope; the driving mechanism rotates forward to cause the guide column to spirally descend along the guide slope.

[0021] As a further improvement, an annular flange is provided around the upper base, and a buffer is provided between the lower end surface of the shell sleeve and the annular flange, which is used to provide the shell sleeve with a vertical travel allowance during the forward rotation cutting process to prevent the shell sleeve from moving downward to abut against the annular flange.

[0022] As a further improvement, the buffer component includes a plate body supported on the lower end surface of the shell and a plurality of columns arranged on the lower end surface of the plate body, the annular flange is provided with through holes adapted to the columns, the columns are each provided with a spring, and the two ends of the spring are respectively connected to the plate body and the annular flange.

[0023] As a further improvement, the side surface of the plug body is provided with a plurality of protrusions, and the interior of the rotating seat is provided with recessed grooves matched with the protrusions, and the plug body slides up and down along the recessed grooves.

[0024] As a further improvement, a limit block protrudes inwardly from the inner lower end of the swing arm. In the initial state, the plug body abuts against the side of the swing arm, and the limit block abuts against the lower end surface of the plug body to limit the plug body from escaping from the accommodating cavity.

[0025] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0026] The automatic stopper-removing bottle opener of the present application is configured to cooperate with each other between the limit shell, the stopper assembly, the cutting mechanism and the lifting mechanism, so that the bottle opener can be mutually transformed between the initial state and the working state, and between the working state and the initial state, so as to realize the cutting of the bottle mouth and the automatic stopper-removing. In the initial state, the stopper body of the stopper assembly is placed in the lower chamber of the accommodating chamber, and is mutually abutted and matched with the swing arm of the cutting mechanism, so that the limit shell is limited to the upper position of the rotating seat. The bottle mouth to be cut enters the lower chamber and pushes the stopper body to slide to the upper chamber, and the initial state is changed to the working state. At this time, the limit shell is pressed downward by the first force-applying component on the pressing inclined surface of the swing arm, so that the swing arm swings inward to limit the downward movement of the stopper body. At the same time, under the lateral pressure of the limit shell, the cutting part on the swing arm extends into the accommodating chamber to abut against the bottle mouth laterally, thereby enhancing the abutment force between the cutting part and the bottle mouth, and making it easier to cut the bottle mouth. After the bottle mouth is cut, it is withdrawn. Driven by the lifting mechanism, the limit shell is lifted upward, and the working state is changed to the initial state. Under the action of the torsion force of the torsion component, the swing arm swings outward, releasing the restriction on the plug body. The plug body rebounds to the lower chamber under the action of the second force-applying component, bringing out the cut bottle cap to achieve automatic plug withdrawal.

[0027] Furthermore, the driving mechanism drives the rotating seat to rotate in the forward direction to cut the bottle mouth, and drives the lifting mechanism in the reverse direction to drive the limiting shell back to the upper position of the rotating seat. Through the lifting plate extended from the limiting shell, the shell sleeve rotatably sleeved on the upper base, the guide column fixed to the shell sleeve, and the guide member arranged on the upper base, the limiting shell rotates to drive the guide column embedded in the guide channel of the lifting plate to move along the guide path provided by the guide member. In the working state, the guide column abuts against the upper part of the guide channel, and the driving mechanism reverses to drive the guide column to abut against the lifting plate upward along the guide member to lift the limiting shell.

[0028] Further, the guide member is a guide slope, which is arranged along the upper base and spirally arranged around the outer side of the upper base. There are multiple guide slopes, which are arranged equidistantly. When the driving mechanism is reversed, the guide column abuts against the upper side of the guide slope, so that the guide column spirally rises along the guide slope. When the driving mechanism rotates forward, the guide column abuts against the lower side of the adjacent guide slope, so that the guide column spirally descends along the guide slope, so that the driving mechanism is reversed to drive the limit housing to lift.

[0029] Furthermore, a buffer is provided between the shell and the flange of the upper base. During the forward rotation cutting process of the driving mechanism, the buffer provides a vertical travel margin for the shell moving downward to prevent the shell from hard abutting against the annular flange during the downward movement, thereby avoiding damage to components.

[0044] Example 1

[0045] Combination Figures 1 to 5 The present embodiment provides an automatic bottle opener, which has an initial state when not in use and a working state of entering a bottle mouth to be cut for rotary cutting. The bottle opener comprises: an upper base 1, a rotating base 2, a driving mechanism 3, a limiting housing 4, a plug assembly 5, a cutting mechanism 6 and a lifting mechanism 7.

[0046] The rotating seat 2 is rotatably disposed below the upper base 1 and has a receiving chamber 21 with an opening at the bottom. The receiving chamber 21 includes an upper chamber 21A and a lower chamber 21B that are interconnected.

[0047] The driving mechanism 3 is arranged in the upper base 1 to drive the rotating base 2 to rotate. Preferably, the driving mechanism is a stepping motor, which is arranged above the upper base 1, and the output shaft of the motor is connected to the rotating base 2 to control the rotating base 2 to rotate forward and reverse.

[0048] The limiting shell 4 is sleeved on the outside of the rotating base 2 and can move up and down relative to the rotating base 2 . The limiting shell 4 has a first force-applying component 41 for causing the limiting shell 4 to move downward.

[0049] The plug assembly 5 includes a plug body 51 slidably disposed in the accommodating chamber 21 and a second force-applying member 52 abutting between the plug body 51 and the top wall of the upper chamber 21A. The plug body 51 is squeezed by the bottle mouth to be cut and changes from the initial state to the working state when it slides up from the lower chamber 21B to the upper chamber 21A. Preferably, the second force-applying member 52 is a compression spring, one end face of which abuts against the top wall of the upper chamber 21A, and the other end face abuts against the upper end face of the plug body 51. The compression spring is in a compressed state both in the initial state and in the working state.

[0050] The cutting mechanism 6 is disposed between the lower chamber 21B and the inner wall of the limiting housing 4, and includes a swing arm 61 hinged to the rotating seat 2 and a twisting component 62 for swinging the swing arm 61 outward. A cutting portion 61A extending toward the accommodating chamber 21 is provided on one side of the swing arm 61, and a pressing inclined surface 61B protruding toward the limiting housing 4 is provided on the other side. In this embodiment, three cutting mechanisms 6 are provided and are equidistantly arranged on the inner side surface of the rotating seat 2 to evenly cut the bottle mouths to be cut that enter the accommodating chamber 21.

[0051] The lifting mechanism 7 is connected to the limiting shell 4, and is used to lift the limiting shell 4 upward after the bottle mouth is withdrawn, changing from the working state to the initial state, and the plug body 51 rebounds to the lower chamber 21B to automatically withdraw the plug.

[0052] By cooperating with each other among the limit housing 4, the plug assembly 5, the cutting mechanism 6 and the lifting mechanism 7, the bottle opener can be switched between the initial state and the working state, and between the working state and the initial state, so as to realize the cutting of the bottle mouth and the automatic withdrawal of the plug.

[0053] Specifically, in the initial state, the plug body 51 of the plug assembly 5 is placed in the lower chamber 21B of the accommodating chamber 21, and abuts and cooperates with the swing arm 61 of the cutting mechanism 6 to limit the limiting shell 4 to the upper position of the rotating seat 2. The bottle mouth to be cut enters the lower chamber 21B to push the plug body 51 to slide to the upper chamber 21A, and the initial state is changed to the working state. At this time, the limiting shell 4 is pressed downward by the first force-applying component 41 to press the pressing inclined surface 61B on the swing arm 61, so that the swing arm 61 swings inward to limit the downward movement of the plug body 51. At the same time, under the lateral pressure of the limiting shell 4, the cutting portion 61A on the swing arm 61 extends into the accommodating chamber 21 to abut against the bottle mouth laterally, thereby enhancing the abutting force between the cutting portion 61A and the bottle mouth, making it easier to cut the bottle mouth. After the bottle mouth is cut, it is withdrawn. Driven by the lifting mechanism 7, the limiting shell 4 is lifted upward, and the working state is changed to the initial state. Under the action of the torsion force of the torsion component 62, the swing arm 61 swings outward, releasing the restriction on the plug body 51. The plug body 51 rebounds to the lower chamber 21B under the action of the second force-applying component 52, bringing out the cut bottle cap to achieve automatic plug withdrawal.

[0054] See also Figure 4 and Figure 5, the first force-applying member 41 is a compression spring, the upper end face of the compression spring abuts against the rotating seat 2, and the lower end face abuts against the lower end position of the limiting shell 4. The downward pressing thrust of the compression spring is greater than the outward swinging force of the torsion member 62, so as to ensure that after the plug body 51 moves to the upper chamber 21A, when there is no mutual abutment between the plug body 51 and the swing arm 61, under the pressing thrust of the compression spring, the swing arm 61 is swung inward along the pressing inclined surface 61B to limit the downward movement of the plug body 51 and make the cutting part 61A closely abut against the bottle mouth to be cut. In this embodiment, a first boss 22 is provided around the upper end of the rotating seat 2, and a second boss 42 is provided around the lower end of the limiting shell 4. The limiting shell 4 is sleeved on the outside of the rotating seat 2, the upper end face of the compression spring abuts against the first boss 22, and the lower end face abuts against the second boss 42, and the limiting shell 4 is at the upper position of the rotating seat 2, and the compression spring is in a compressed state.

[0055] A cavity 23 for accommodating the swing arm 61 is provided on the side of the rotating seat 2. The swing arm 61 is hinged to the side of the rotating seat 2 so as to swing inward and outward through the cavity 23. The torsion component 62 is a torsion spring, which is sleeved on the swing arm 61, and one end of the torsion spring abuts against the side of the swing arm 61, and the other end abuts against the rotating seat 2. In the initial state, when the plug body 51 and the swing arm 61 abut against each other, both ends of the torsion spring are in the initial position and no energy is stored temporarily. In the working state, the limit shell 4 presses the protruding pressing slope 61B, and the swing arm 61 swings inward. At this time, the end of the torsion spring abutting against the side of the swing arm 61 is in a torsion position and stores energy. After the limit shell 4 is lifted, the restriction on the swing arm 61 is released, and the torsion spring releases the torsion force to return to the initial position, so that the swing arm 61 swings outward to its original position. The pressing bevel 61B is protruding toward the limiting shell 4, and the limiting shell 4 is at the upper position of the rotating seat 2. The lowest point of the pressing bevel 61B abuts against the lower end surface of the limiting shell 4. After the plug body 51 moves to the upper chamber 21A, the limiting shell 4 presses the rest of the pressing bevel 61B downward along the lowest point of the pressing bevel 61B to squeeze the swing arm 61 inward.

[0056] See also Figure 5 and Figure 6, the driving mechanism 3 drives the rotating seat 2 to rotate in the forward direction to cut the bottle mouth, and drives the lifting mechanism 7 to drive the limiting shell 4 back to the upper position of the rotating seat 2 in the reverse direction. In this embodiment, the lifting mechanism 7 includes a lifting plate 71 extending upward along the limiting shell 4 to one side of the upper base 1, a shell 72 rotatably sleeved on the outer surface of the upper base 1, a guide column 73 fixed on the shell 72, and a guide member 74 arranged on the upper base 1. The rotation of the limiting shell 4 can drive the lifting plate 71 connected thereto to rotate synchronously, and the first boss 22 of the rotating seat 2 is recessed with an avoidance groove 22A to avoid the lifting plate 71 extending upward, and when the rotating seat 2 rotates forward and reversely, the lifting plate 71 abuts against the groove wall of the avoidance groove 22A to drive the lifting plate 71 to rotate. The guide member 74 provides an upward guide path for the guide column 73. The lifting plate 71 is provided with a vertically arranged guide channel 71A. The guide column 73 is movably embedded in the guide channel 71A. The limit housing 4 rotates to drive the guide column 73 to move along the guide path. In the working state, the guide column 73 abuts against the upper part of the guide channel 71A. The driving mechanism 3 reverses and drives the guide column 73 embedded in the guide channel 71A to abut against the lifting plate 71 upward along the guide member 74, so as to lift the limit housing 4 and realize the lifting of the limit housing 4.

[0057] See also Figure 6 The guide member 74 is a guide slope arranged on the outer wall of the upper base 1. The guide slope has a guide path arranged spirally upward, and there are multiple guide slopes, which are arranged equidistantly. Preferably, the guide slope, the lifting plate 71, and the guide column 73 are all provided in three. The lifting plate 71, the guide column 73, and the guide slope are provided in a matching manner, and there are three guide slopes, which ensures that the lifting force of the guide column 73 on the lifting plate 71 is enhanced and the guide slope effectively guides the guide column 73.

[0058] When the driving mechanism 3 is reversed, the guide post 73 abuts against the upper side of the guide slope, so that the guide post 73 spirally rises along the guide slope. When the driving mechanism 3 is forward, the guide post 73 abuts against the lower side of the adjacent guide slope, so that the guide post 73 spirally descends along the guide slope. In this embodiment, three equally spaced guide slopes are arranged around the outer side of the upper base 1 and spirally arranged upward, so that the driving mechanism 3 reverses and drives the limit housing 4 to rise.

[0059] Specifically, the guide post 73 is fixed on the shell 72, and the shell 72 is rotatably sleeved on the outer side of the upper base 1. The outer end of the guide post 73 is embedded in the guide channel 71A, and can move up and down in the guide channel 71A through the guide path of the guide slope. The inner end of the guide column 73 is just set between two adjacent guide slopes. When the lifting plate 71 is reversed, it drives the guide column 73 to abut against the upper end surface of the guide slope, so as to drive the guide column 73 to move upward in the guide channel 71A. The outer end of the guide column 73 abuts the upper part of the guide channel 71A, and lifts the lifting plate 71 to the position where the limiting shell 4 returns to the initial state, that is, the limiting shell 4 is limited to the upper position of the rotating seat 2. At this time, the guide column 73 enters the adjacent guide slope along the upper end surface outlet of the guide slope. Under the action of the gravity of the shell 72, the guide column 73 descends a distance along the guide channel 71A and reaches the upper end surface of the adjacent guide slope. After abutting the upper end surface of the guide slope, the guide column 73 moves upward until it reaches the upper end surface outlet of the guide slope, and so on. When the lifting plate 71 rotates forward, it drives the guide column 73 to abut against the lower end face of the adjacent guide slope. At this time, the guide column 73 moves downward in the guide channel 71A, and the outer end of the guide column 73 moves downward in the guide channel 71A and there is a certain distance between it and the lower part of the guide channel 71A. The guide column 73 enters the guide slope along the exit of the lower end face of the guide slope, and the lifting plate 71 continues to rotate forward, and the guide column 73 abuts against the lower end face of another adjacent guide slope, and performs reciprocating motion in this way.

[0060] See also Figure 6 , an annular flange 1A is provided around the upper base 1, and a buffer 8 is provided between the lower end surface of the shell 72 and the annular flange 1A, which is used to provide a vertical travel margin for the shell 72 during the forward rotation cutting process to prevent the shell 72 from moving downward to abut against the annular flange 1A. In this embodiment, the buffer 8 includes a plate body 8A supported on the lower end surface of the shell 72 and a plurality of columns 8B provided on the lower end surface of the plate body 8A. A through hole 1B adapted to the column 8B is provided on the annular flange 1A, and the columns 8B are all sleeved with a spring 8C, and the two ends of the spring 8C are respectively connected to the plate body 8A and the annular flange 1A. When the lifting plate 71 rotates forward, the guide column 73 drives the shell sleeve 72 to move downward, and the lower end surface of the shell sleeve 72 abuts against the upper end surface of the plate body 8A of the buffer member 8. The shell sleeve 72 continues to move downward, and the plate body 8A passes through the through hole 1B opened in the annular flange 1A through the column 8B, and the spring 8C sleeved on the column 8B is in a compressed state. The buffer member 8 presses downward to buffer, preventing the shell sleeve 72 from hard abutting against the annular flange 1A during the downward movement, thereby avoiding damage to components.

[0061] See also Figure 7The side of the plug body 51 has a plurality of protrusions 51A, and the interior of the rotating seat 2 is provided with recessed grooves 24 that match the protrusions 51A, and the plug body 51 slides up and down along the recessed grooves 24. The plug body 51 is easy to slide up and down in the accommodating cavity through the cooperation between the protrusions 51A and the recessed grooves 24, and further restricts the plug body 51 from rotating in the accommodating cavity 21, so that when the bottle mouth to be cut pushes the plug body 51 to enter the accommodating cavity 21, the plug body 51 will not rotate or tilt in the accommodating cavity 21, which will affect the entry of the bottle mouth.

[0062] Furthermore, a stopper 61C is protruded inwardly at the inner lower end of the swing arm 61. In the initial state, the plug body 51 abuts against the side of the swing arm 61, and the stopper 61C abuts against the lower end surface of the plug body 51 to limit the plug body 51 from escaping from the accommodating cavity 21. In the initial state, the plug body 51 and the swing arm 61 abut against each other, and the stopper 61C at the inner lower end of the swing arm 61 abuts against the lower end surface of the plug body 51, realizing the limitation of the side and lower end surfaces of the plug body 51.

[0063] The working mode of the bottle opener of this embodiment is as follows:

[0064] The user pushes the plug body 51 against the bottle mouth to be cut, and the plug body 51 enters the lower chamber 21B of the accommodating chamber 21. The plug body 51 is pushed and slides to the upper chamber 21A, and the bottle opener of the present application changes from the initial state to the working state. At this time, the limiting shell 4 is pressed downward by the first force-applying component 41 on the pressing slope 61B on the swing arm 61, so that the swing arm 61 swings inward. Under the lateral pressure of the limiting shell 4, the cutting portion 61A on the swing arm 61 extends into the accommodating chamber 21 to abut against the bottle mouth laterally. At this time, the driving mechanism 3 is started to rotate forward, and the rotating seat 2 rotates to drive the cutting portion 61A to cut the bottle mouth. After the bottle mouth is cut, exit, start the driving mechanism 3 to reverse, and the lifting mechanism 7 drives the limiting shell 4 to lift upward, and the limiting shell 4 returns to the upper position of the rotating seat 2. At this time, under the torque of the twisting component 62, the swing arm 61 swings outward, releasing the restriction on the plug body 51. The plug body 51 rebounds to the lower chamber 21B under the action of the second force-applying component 52, bringing out the cut bottle cap, completing the automatic plug removal.

[0065] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
