Description

Technical Field

[0001] The present invention relates to the technical field of portable household appliances, and particularly relates to an electric wine opener. Background Art

[0002] At present, most electric wine openers on the market usually hold the wine bottle tightly with one hand and hold the wine opener tightly with the other hand and press the control button on the wine opener to perform the wine opening operation. This operation method is inconvenient and the wine opener is not intelligent enough. The existing Chinese invention patent with the application number 201910383205.5 provides a fully automatic wine opener, including a cylindrical outer shell. The interior of the outer shell is hollow to form a receiving space with an opening at the bottom. A movement mechanism is provided in the upper part of the receiving space. The movement mechanism includes a motor and a speed reducer. The lower end of the speed reducer extends downward to be provided with a drill bit. The motor, the speed reducer, and the drill bit are all axially floating in the receiving space. The movement mechanism further includes a trigger switch that follows the motor. When the drill bit is axially moved backward by the acting force of the wine bottle cork, the movement mechanism moves upward synchronously. When the trigger switch moves axially upward along the wine opener and touches the inner wall of the upper end of the receiving space, the trigger signal it emits serves as a trigger condition for starting the motor, and the wine opener starts to pull out the cork. Then when the cork moves upward and abuts against the elastic piece of the stop switch, the wine opener automatically performs the operation of pushing out the cork.

[0003] The above technical solution has the following deficiencies: Although it realizes fully automatic wine opening without button control, if both hands are not used at the same time, or the hand holding the wine bottle is not held tightly, the wine bottle will rotate and slip during the wine opening operation, and the wine opening operation cannot be implemented. Especially for people with disabilities in the hands or people with hand diseases who can only use one hand, a fully automatic wine opener that can be operated with one hand is needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a portable and durable fully automatic electric wine opener that can be easily operated with one hand and the spiral hook assembly is not easily worn.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings of the present invention.

[0033] Embodiment 1, referring to Figures 1 to 10 , an electric wine bottle opener includes a housing 1, an output shaft 2, an output shaft sleeve 3, a guide sleeve 4, a spiral hook 5, and a bottle opening sleeve 6. The output shaft 2 is inserted into the output shaft sleeve 3. One end of the output shaft sleeve 3 passes through the guide sleeve 4 and is fixedly connected to the spiral hook head 51. The guide sleeve 4 is fixedly connected to the inner side of the housing 1. It further includes two clamping pieces 7 and an elastic device 8. The elastic device 8 is installed between the clamping piece 7 and the bottle opening sleeve 6. The upper end of the clamping piece 7 is movably connected to the lower end of the bottle opening sleeve 6. The clamping pieces 7 enclose a space that can accommodate the mouth of a wine bottle.

[0034] A magnet 21 is fixedly installed at the end of the output shaft 2. The magnet 21 attracts the head 51 of the spiral hook to achieve the connection between the output shaft 2 and the output shaft sleeve 3. The setting of the magnet 21 ensures that the spiral hook 5 can reset to the initial working state, and at the same time avoids the spiral hook 5 falling out of the bottle opener and hurting people when the bottle opener is not working. A positioning hole 32 matching the head 51 of the spiral hook is arranged at the lower part inside the output shaft sleeve 3. The shapes of the head 51 of the spiral hook and the positioning hole 32 are arbitrary. In this embodiment, they are selected to be cylindrical. After the head 51 of the spiral hook is placed into the positioning hole 32, the output shaft sleeve 3 and the spiral hook 5 are fixedly connected by inserting a first pin 52 into the through holes on the output shaft sleeve 3 and the head 51 of the spiral hook, so that the output shaft sleeve 3 can move together with the spiral hook 5.

[0035] The cross-section of the output shaft 2 is non-circular. An upper part inside the output shaft sleeve 3 is provided with a non-circular through hole 31 that cooperates with the output shaft 2. In this embodiment, the output shaft 2 with a square cross-section and the through hole 31 with a square cross-section that cooperates with it are selected, so that the output shaft 2 can drive the output shaft sleeve 3 to rotate. The length of the through hole 31 is smaller than the length of the output shaft 2, so that the upward movement distance of the spiral hook 5 is limited. A limiting protrusion 33 is provided at the upper end of the output shaft sleeve 3. A guide sleeve 4 is sleeved outside the output shaft sleeve 3. The limiting protrusion 33 can move with the output shaft sleeve 3 to the upper side of the guide sleeve 4, so that the downward movement distance of the spiral hook 5 is limited, that is, the opening stroke is controlled to prevent damage during the use of the bottle opener. The guide sleeve 4 is provided with an annular groove 41, and an inner side of the housing 1 is provided with a convex ring 11 that matches the annular groove 41. The convex ring 11 can be inserted into the groove 41 to fix the guide sleeve 4 inside the housing 1. A guide hole 42 that cooperates with the output shaft sleeve 3 is provided in the middle of the guide sleeve 4. The contact surface between the output shaft sleeve 3 and the guide hole 42 has a small friction coefficient and is not afraid of wear, so that the output shaft sleeve 3 and the guide sleeve 4 are wear-resistant and durable, and the service life of the bottle opener is improved.

[0036] Two raised blocks 61 integrally formed with the bottle-opening sleeve 6 are provided at the lower end of the bottle-opening sleeve 6. Two ear pieces 71 integrally formed with the holding piece 7 are provided at the upper end of each holding piece 7. The bottle-opening sleeve 6 and the holding piece 7 are movably connected by inserting a second pin 72 into the through holes on the ear pieces 71 and the raised blocks 61. The holding piece 7 can rotate around the second pin 72 to form a seesaw structure for the holding piece 7 to contract and hold the mouth of the red wine bottle. A positioning surface 611 that obliquely opens outward from top to bottom towards the bottle-opening sleeve 6 is provided inside the raised block 61. An inclined mating surface 711 in the same direction that cooperates with the positioning surface 611 is provided between the two ear pieces 71. The positioning surface 611 and the mating surface 711 are in contact to limit the excessive opening when the holding piece 7 resets and ensure that the holding piece 7 can be recycled.

[0037] Four fixing grooves 73 are symmetrically arranged at the top of the holding piece 7 and the bottom of the bottle opening sleeve 6. The elastic device is four thrust springs 8. Other elastic devices with the same effect can also be selected. One end of the thrust spring 8 abuts against the fixing groove 73 at the top of the holding piece 7, and the other end of the thrust spring 8 abuts against the fixing groove 73 at the bottom of the bottle opening sleeve 6. The thrust spring 8 is compressed when the holding piece 7 is gathered toward the center to hold the mouth of the red wine bottle tightly. When the cork needs to be removed, the bottle opener is pulled out from above the mouth of the red wine bottle. The thrust spring 8 can quickly restore the holding piece 7 from the state of gathering and clamping the mouth of the red wine bottle to the original state to release the bottle mouth, thereby preventing the red wine bottle from being lifted or overturned.

[0038] An anti-skid pad 74 is provided on the inner side of the holding piece 7, and the anti-skid pad 74 is fixedly connected to the holding piece 7. The anti-skid pad 74 increases the friction between the mouth of the red wine bottle and the holding piece 7, so that the holding piece 7 can more firmly fix the red wine bottle during the bottle opening operation.

[0039] The electric wine bottle opener also includes a brake assembly 9, which includes a pre-stressed spring 91, an inner front shell 92, an inner rear shell 93, a control PCB board 94, a battery pack 95, a motor 96, a gear box assembly 97, and an output shaft 2. The motor 96 and the gear box assembly 97 are coaxially fixedly connected and fixedly arranged in a cavity surrounded by the inner front shell 92 and the inner rear shell 93. The control PCB board 94 is fixedly arranged on the inner side of the shell 1. A charging socket 941 and a reset trigger switch 942 are electrically connected to the control PCB board 94, and an opening is arranged at a corresponding position of the shell 1; the battery pack 95 is arranged in the upper part of the cavity, and the output shaft 2 is coaxially fixedly connected to the gear box assembly 97 and then extends from the lower side of the cavity. There are spring shoulders matching the preload spring 91 at the top of the inner front shell 92 and the inner rear shell 93. One end of the preload spring 91 abuts against the spring shoulder, and the other end abuts against the inner wall of the upper end of the shell 1. The lower ends of the inner front shell 92 and the inner rear shell 93 abut against the limit platform 12 on the inner side of the shell 1. The brake assembly 9 can only move up and down in the shell 1. The brake assembly 9 transmits downward pressure to the spiral hook 5 through the output shaft 2 at its lower part.

[0040] Inside the bottle opener sleeve 6, from top to bottom, there are also an upper cover 62 of the bottle opener sleeve, a spring 63 of the bottle opener sleeve, and a lower cover 64 of the bottle opener sleeve. The lower cover 64 of the bottle opener sleeve can move up and down within the bottle opener sleeve 6 along the ribs 65 on the inner side of the bottle opener sleeve. There is an integrally connected shoulder 66 at the upper end of the bottle opener sleeve 6. Due to the limiting structure inside the housing 1, the bottle opener sleeve 6 can only move linearly up and down relative to the housing 1, and there are a second limiting platform 13 and a third limiting platform 14 on the inner side of the housing 1 to limit the up and down movement distance of the bottle opener sleeve. A bottle opening trigger switch 131 electrically connected to the control PCB board 94 is also provided on the second limiting platform 13. When the bottle opener sleeve 6 moves upward, the bottle opening trigger switch 131 can be opened through the shoulder 66. From bottom to top on the upper side of the bottle opener sleeve 6, there are also a guiding spring 67, a limiting sleeve 68, and a reset spring 69 in sequence. One end of the guiding spring 67 abuts against the upper part of the bottle opener sleeve 6, and the other end abuts against the lower side of the fourth limiting platform 15 on the inner side of the housing 1. One end of the limiting sleeve 68 abuts against the upper side of the fourth limiting platform 15, and the other end abuts against one end of the reset spring 69. The other end of the reset spring 69 abuts against the lower side of the fifth limiting platform 16 on the inner side of the housing 1. The limiting sleeve 68 can move up and down between the fourth limiting platform 15 and the fifth limiting platform 16, and when the limiting sleeve 68 moves upward, it can trigger a limiting trigger switch 151 located on the fourth limiting platform 15.

[0041] The working principle of the fully automatic single - hand red wine bottle cork opener of the present invention will be explained below:

[0042] In the first step, align the space formed by enclosing between the clamping pieces 7 with the mouth of the red wine bottle, and press down the body of the opener. When the top surface of the bottle mouth abuts against the inner wall of the upper end of the clamping piece 7, since the thrust of the thrust spring 8 is greater than the pressure of the guiding spring 67, when pressing down the body of the opener and moving downward, the thrust spring 8 is not compressed, while the guiding spring 67 is compressed. The bottle opener sleeve 6 and the clamping piece 7 are both stationary relative to the bottle mouth, and the clamping piece 7 does not start to act.

[0043] In the second step, continue to press down the body of the opener until the tip of the spiral hook 5 abuts against the wine cork. Due to the downward pressure of the braking assembly 9, the pressure in this embodiment includes the elastic force of the pre - pressing spring 91 and the gravity of the braking assembly 9, which causes the tip of the spiral hook 5 to be under pressure and penetrate into the wine cork. At the same time, due to the downward movement of the body of the opener, the bottle opening trigger switch 131 installed on the lower side of the second limiting platform 13 moves downward together with the housing 1 until the bottle opening trigger switch 131 is triggered by the shoulder 66. After the bottle opening trigger switch 131 is triggered, it sends a delayed start signal to the MCU on the control PCB board 94. The MCU starts the motor 96 to rotate forward after a delay of a period of time T0.

[0044] Step 3: During the process that the housing 1 moves downward until the second limiting platform 13 abuts against the shoulder 66 of the bottle opener sleeve 6, the bottle opener sleeve 6 remains stationary relative to the wine bottle all the time. After the bottle opening trigger switch 131 is triggered, a downward acting force given by the user acts on the housing 1 and then acts on the bottle opener sleeve 6, causing the housing 1 to drive the bottle opener sleeve 6 to move downward together. Meanwhile, the thrust spring 8 is compressed. When the bottle opener sleeve 6 moves downward relative to the clamping piece 7, due to the seesaw structure of the clamping piece 7, the clamping piece 7 receives an upward reaction force from the top of the wine bottle mouth. The clamping piece 7 will rotate inwardly towards the center along the second pin 72, causing the opening of the clamping piece 7 to shrink, thereby clamping the wine bottle mouth. T0 can be freely set to ensure that the motor 96 is started only after the clamping piece 7 clamps the wine bottle mouth.

[0045] Step 4: After the motor 96 is started, the output end of the motor 96 rotates at a high speed to drive the gearbox assembly 97 and then drives the output shaft 2 to rotate at a low speed. The output shaft 2 drives the output shaft sleeve 3 sleeved thereon to rotate, thereby driving the spiral hook 5 to rotate. The motor 96 starts to rotate forward to start the cork pulling operation. The first stage: The frictional force between the spiral hook 5 and the cork is decomposed into a vertically downward force and a horizontally forward rotating force. The spiral hook 5 can move downward to get rid of the suction force of the magnet 21 on the output shaft 2. During this process, the cork remains stationary relative to the wine bottle mouth, and the spiral hook 5 moves downward and rotates horizontally forward relative to the cork at the same time until the guide sleeve 4 restricts the vertical displacement of the output shaft sleeve 3. At this time, the bottle opening operation enters the second stage. The spiral hook 5 only makes a horizontally forward rotating motion and does not move up and down. The frictional force between the cork and the spiral hook 5 acts on the cork in the opposite direction. The cork receives an upward traction force and a rotating force. Under the combined action of the rib 65 in the bottle opener sleeve 6 that prevents the cork from rotating, the cork starts to move upward into the bottle opener sleeve 6. As the spiral hook 5 continues to rotate, the cork drives the bottle opener lower cover 64 that can move up and down in cooperation with the rib 65 in the bottle opener sleeve 6 to continue to move upward until the bottle opener lower cover 64 drives the limit sleeve 68 to move upward to trigger the limit switch 151 or after the motor 96 rotates forward for the set bottle opening time T1, the motor 96 stops working, causing the spiral hook 5 and the cork to stop moving upward, thereby realizing the cork pulling action and finally completing the bottle opening operation.

[0046] Step 5: After the motor 96 stops rotating forward, when the bottle opener is lifted upward from the wine bottle mouth, the elastic force of the thrust spring 8 quickly pushes the clamping piece 7 back to its original position to prevent the clamping piece 7 from lifting or tipping over the wine bottle.

[0047] Step 6: When the motor 96 reaches the set stop time T2, the motor 96 starts to reverse and begins the cork withdrawal operation. First stage: The frictional force between the spiral hook 5 and the cork is decomposed into a vertically upward force and a horizontally reverse rotational force. Plus the downward thrust of the guiding spring 65, while the bottle opener sleeve 6 and the cork move downward relatively stationary, the spiral hook 5 only makes a horizontally reverse rotational movement. When the shoulder 66 touches the third limiting platform 14, the bottle opener sleeve 6 cannot continue to move downward to complete the reset of the bottle opener sleeve 6. During the downward movement of the bottle opener sleeve 6, it drives the lower cover 64 of the bottle opener sleeve located in the upper part of the bottle opener sleeve 6 to move downward together and gradually disengages from the limiting sleeve 68. At the same time, the limiting sleeve 68 gradually moves to the upper side of the fourth limiting platform 15 under the action of the reset spring 69 to complete the reset. Since the movable range of the limiting sleeve 68 between the fourth limiting platform 15 and the fifth limiting platform 16 is smaller than the movable range of the bottle opener sleeve 6 between the second limiting platform 13 and the third limiting platform 14, the reset movement of the limiting sleeve 68 is completed earlier than the reset movement of the bottle opener sleeve 6. Second stage: The spiral hook 5 moves upward and makes a horizontally reverse rotational movement relative to the cork and the bottle opener sleeve 6 simultaneously. During this stage, the bottle opener sleeve 6 and the cork are relatively stationary with respect to the bottle opener. When the spiral hook 5 moves upward to the initial working state, that is, when the magnet 21 adsorbs the head 51 of the spiral hook, the cork withdrawal operation enters the third stage: The spiral hook 5 cannot continue to move upward and only makes a horizontally reverse rotational movement. At this time, the frictional force reacts on the cork, and the cork is subjected to a downward traction force and a rotational force. Under the combined action of the rib 65 in the bottle opener sleeve 6 that prevents the cork from rotating, the cork begins to come out downward from the bottle opener sleeve 6. When the motor 96 reverses and reaches the set cork withdrawal time T3, it stops, thus realizing the cork withdrawal action and finally completing the cork withdrawal operation.

[0048] When a situation of cork jamming or the spiral hook 5 not being able to return to its normal position occurs during the bottle opening process, press the reset trigger switch 942 to implement the cork withdrawal operation and make the bottle opener return to the reset state. During the whole bottle opening process, only need to gently press the mouth of the wine bottle downward with one hand, so that the clamping piece 7 clamps the mouth of the wine bottle during the cork pulling process. The cork pulling and cork withdrawal processes are both automatically realized, and the operation is extremely simple.

[0049] Refer to Figure 11 and Figure 12 , in the second and third embodiments of the present invention, their basic structures and working principles are the same as those of the first embodiment above. The difference is that one end of the output shaft sleeve 3 is fixedly connected to the head 51 of the spiral hook and the spiral hook 5 passes through the guiding sleeve 4, that is, the lengths of the output shaft 2 and the output shaft sleeve 3 used in cooperation with it are different from those in the first embodiment, and the lengths of the output shaft 2 and the output shaft sleeve 3 can be freely changed within a certain range according to needs. As Figure 2 shown in the first embodiment, one end of the output shaft sleeve 3 passes through the guiding sleeve 4; Figure 11 shown in the second embodiment, a part of one end of the output shaft sleeve 3 is inserted into the guiding hole 42; Figure 12In the third embodiment shown, the output shaft sleeve 3 is suspended above the center of the guide sleeve 4. In the above three embodiments, the length of the spiral hook 5 changes with the length of the output shaft sleeve 3, but the relative position of the tip of the spiral hook 5 with respect to the housing 1 is consistent, and it can always meet the normal operation of the bottle opener.

[0050] The above-described embodiments are specific descriptions of the feasible embodiments of the present invention. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this patent. Any equivalent implementation or modification without departing from the present invention shall fall within the scope of protection of this patent.
