The control button is electrically connected to the micro-drive motor, and a threaded shaft is arranged to cooperate with the telescopic rod, and a limit sleeve is arranged to cooperate with the slide groove for limiting. The threaded shaft rotates to drive the telescopic rod to rise or fall, and a threaded groove matching the rotating sleeve is arranged on the inner side of the shell. When the telescopic rod drives the rotating sleeve to move up and down, the rotating sleeve rotates automatically. Multiple sets of precision transmission systems are arranged inside the shell to transmit the rotation output of the micro-drive motor to the rotation and up and down movement of the spiral hook.

[0003] This technical solution has the following shortcomings: although the up and down movement of the spiral hook is achieved by the cooperation between the threaded shaft and the threaded groove at the top of the telescopic rod, and the cooperation between the thread on the outside of the rotating sleeve and the threaded groove on the inner side of the shell, the structure of the cooperation between the thread and the threaded groove is easy to wear, and long-term use will make the thread or the threaded groove smooth, so that the bottle opener cannot work normally, and the structure of the cooperation between the thread and the threaded groove is relatively complicated, which has higher requirements for the production process. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned shortcomings and provide an electric wine bottle opener with simple structure and durability.

[0005] In order to achieve the above purpose, the present invention provides an electric wine bottle opener, and the specific technical scheme is as follows: an electric wine bottle opener, comprising a housing, an output shaft, an output shaft sleeve, a guide sleeve, and a spiral hook, wherein the output shaft is connected to the output shaft sleeve, one end of the output shaft sleeve passes through the guide sleeve and is fixedly connected to the head of the spiral hook, or one end of the output shaft sleeve is fixedly connected to the head of the spiral hook and the spiral hook passes through the guide sleeve, and the guide sleeve is fixedly connected to the inner side of the housing. The output shaft sleeve can move up and down relative to the output shaft in the guide sleeve along the central axis direction of the bottle opener.

[0006] A magnet is also provided between the output shaft and the output shaft sleeve. The magnet is fixedly mounted on the end of the output shaft. The connection between the output shaft and the output shaft sleeve is achieved by the magnet attracting the spiral hook head.

[0007] The cross section of the output shaft is non-circular, a through hole with a non-circular cross section matching the output shaft is arranged at the upper position inside the output shaft sleeve, and a positioning hole matching the spiral hook head is arranged at the lower position inside the output shaft sleeve. The length of the through hole is smaller than the length of the output shaft. A limiting protrusion is arranged at the upper end of the output shaft sleeve.

[0008] The spiral hook head is cylindrical and is provided with a spiral hook head through hole. The lower part of the output shaft sleeve is provided with a sleeve through hole. After the spiral hook head is inserted into the positioning hole at the lower part of the output shaft sleeve, a pin penetrates the sleeve through hole and the spiral hook head through hole at the same time, so as to realize the fixed connection between the output shaft sleeve and the spiral hook.

[0009] The guide sleeve is provided with an annular groove, and a convex ring matching the groove is provided on the inner side of the shell body, and the convex ring can be inserted into the groove.

[0010] The beneficial effects of the present invention are as follows: the non-circular output shaft is inserted into the non-circular through hole in the output shaft sleeve matched therewith, and when the output shaft rotates, the output shaft sleeve is driven to rotate, thereby realizing the rotational movement of the spiral hook; the cooperation between the output shaft and the through hole and the cooperation between the limiting protrusion and the guide sleeve limit the range of up and down movement of the spiral hook, so that when the body of the bottle opener and the wine bottle remain relatively still during the bottle opening process, the spiral hook and the output shaft sleeve automatically move up and down to complete the bottle opening operation; the structure of the output shaft sleeve and the guide sleeve is simple and easy to produce, and the contact surface friction coefficient of the output shaft sleeve and the guide sleeve is small and not afraid of wear, thereby greatly improving the service life of the bottle opener.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0021] Embodiment 1, refer to Figures 1 to 5 An electric wine bottle opener includes a shell 1, an output shaft 2, an output shaft sleeve 3, a guide sleeve 4, and a spiral hook 5. The output shaft 2 is connected to 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 shell 1. The output shaft sleeve 3 can move up and down relative to the output shaft 2 in the guide sleeve 4 along the central axis direction of the bottle opener.

[0022] A magnet 21 is provided between the output shaft 2 and the output shaft sleeve 3, and the magnet 21 is fixedly mounted at the end of the output shaft 2. The connection between the output shaft 2 and the output shaft sleeve 3 is achieved by the magnet 21 sucking the spiral hook head 51. The arrangement of the magnet 21 ensures that the spiral hook 5 can be reset to the initial working state, and at the same time prevents the spiral hook 5 from falling out of the bottle opener and injuring people when the bottle opener is not working.

[0023] A through hole 31 with a non-circular cross section that matches the output shaft 2 is provided at the upper position inside the output shaft sleeve 3. When the output shaft 2 rotates, the output shaft sleeve 3 is driven by the output shaft 2 with a non-circular cross section, thereby driving the spiral hook 5 to rotate. In this embodiment, the output shaft 2 with a square cross section and the through hole 31 with a square cross section that matches therewith are selected. A positioning hole 32 that matches the spiral hook head 51 is provided at the lower position inside the output shaft sleeve 3. The spiral hook head 51 and the positioning hole 32 that matches therewith are of any shape. In this embodiment, a cylindrical shape is selected. The length of the through hole 31 is smaller than the length of the output shaft 2, so that the distance that the spiral hook 5 moves upward is limited. A limiting protrusion 33 is provided at the upper end of the output shaft sleeve 3, so that the limiting protrusion 33 moves downward to the upper side of the guide sleeve 4 at most, that is, the distance that the spiral hook 5 moves downward is limited, and the stroke of opening the bottle is controlled to prevent the bottle opener from being damaged during use.

[0024] It also includes a pin 7 for fixing the output shaft sleeve 3 and the spiral hook 5. A spiral hook head through hole 511 is provided on the spiral hook head 51. A sleeve through hole 34 is provided at the lower part of the output shaft sleeve 3. After the spiral hook head 51 is inserted into the positioning hole 32 at the lower part of the output shaft sleeve 3, the pin 7 penetrates the sleeve through hole 34 and the spiral hook head through hole 511 at the same time, so that the output shaft sleeve 3 and the spiral hook 5 are fixedly connected, so that the output shaft sleeve 3 and the spiral hook 5 can rotate and move up and down together.

[0025] The guide sleeve 4 is provided with an annular groove 41, and a convex ring 11 matching the groove 41 is provided on the inner side of the housing 1, and the convex ring 11 can be inserted into the groove 41, so as to fix the guide sleeve 4 in the housing 1. A guide hole 42 matching the output shaft sleeve 3 is provided in the middle of the guide sleeve 4, and the contact surface friction coefficient between the output shaft sleeve 3 and the guide hole 42 is small and not afraid of wear, so that the output shaft sleeve 3 and the guide sleeve 4 are wear-resistant and durable, thereby improving the service life of the bottle opener.

[0026] The electric wine bottle opener also includes a brake assembly 8, which is installed in the upper part of the housing 1, and the upper and lower ends of the brake assembly 8 abut against the housing 1. The brake assembly 8 includes a pre-compression spring 81, a motor 82, and a reduction gear box 83. The pre-compression spring 81 abuts against the upper end of the housing 1, and the output end of the motor 82, the reduction gear box 83 and the output shaft 2 are coaxially connected. When the bottle opener is used, the brake assembly 8 is subjected to the upward pressure given by the spiral hook 5 and can move upward.

[0027] The principle of the spiral hook 5 moving up and down along the central axis in the bottle opener when the bottle opener is used is: the output end of the motor 82 rotates at a high speed to drive the reduction gear box 83, and then drives the output shaft 2 to rotate at a low speed, and the output shaft 2 drives the output shaft sleeve 3 mounted thereon to rotate, thereby driving the spiral hook 5 to rotate. When opening the bottle, the user puts the bottle opener on the mouth of the red wine bottle and presses it downward. At this time, the tip of the lower end of the spiral hook 5 is pressed downward on the wine cork by the brake assembly 8. The pressure in this embodiment includes the elastic force of the pre-compression spring 81 and the gravity of the brake assembly 8, so that the tip of the spiral hook 5 pierces the wine cork. When the bottle opening operation is started and the spiral hook 5 rotates forward, in the first stage: the friction force between the spiral hook 5 and the wine cork is decomposed into vertical downward force and horizontal positive rotation force, and the spiral hook 5 can get rid of the suction force of the magnet 21 on the output shaft 2 and move downward. In this process, the wine cork is stationary relative to the bottle mouth, and the spiral hook 5 moves downward and rotates horizontally forward relative to the wine cork at the same time, until the guide sleeve 4 limits the vertical displacement of the output shaft sleeve 3. At this time, the bottle opening operation enters the second stage, and the spiral hook 5 only makes horizontal positive rotation movement and does not move up and down. The friction between the wine cork and the spiral hook 5 The friction force acts on the wine cork, which is subjected to upward traction and rotational force. Under the joint action of the ribs 61 in the bottle opener 6 that prevent the wine cork from rotating, the wine cork begins to enter the bottle opener 6. As the spiral hook 5 continues to rotate, the wine cork drives the bottle opener lower cover 62 in the bottle opener 6 that can move up and down with the ribs 61 to continue to move upward until the bottle opener lower cover 62 drives the limit sleeve 63 to move upward and triggers the limit switch 64. The motor 82 stops working, causing the spiral hook 5 and the wine cork to stop moving upward, thereby realizing the bottle opening and cork removal action and finally completing the bottle opening operation.

[0028] When the cork removal operation is started and the spiral hook 5 is reversed, in the first stage, the friction force between the spiral hook 5 and the wine cork is decomposed into vertical upward and horizontal reverse rotation forces, and coupled with the downward thrust of the guide spring 65, the bottle opening sleeve 6 and the wine cork are relatively stationary while moving downward, and the spiral hook 5 only performs horizontal reverse rotation movement. When the bottle opening sleeve 6 is restricted by the shell 1 and cannot continue to move downward, the bottle opening sleeve 6 is reset; in the second stage, the spiral hook 5 simultaneously moves upward and horizontally reversely rotates relative to the wine cork and the bottle opening sleeve 6. In this stage, the bottle opening sleeve 6 and the wine cork are stationary relative to the bottle opener. When the spiral hook 5 moves upward to the initial working state, that is, the magnet 21 adsorbs the spiral hook head 51, the cork removal operation enters the third stage: the spiral hook 5 cannot continue to move upward, and only has horizontal reverse rotation movement. At this time, the friction force reacts on the wine cork, and the wine cork is subjected to downward traction and rotation force. Under the joint action of the ribs 61 in the bottle opening sleeve 6 that prevent the wine cork from rotating, it begins to fall out of the bottle opening sleeve 6 downward, thereby realizing the cork removal action and finally completing the cork removal operation.

[0029] Reference Figure 6 and Figure 7In the second and third embodiments of the present invention, the basic structure and working principle are the same as those of the first embodiment, except that one end of the output shaft sleeve 3 is fixedly connected to the spiral hook head 51 and the spiral hook 5 passes through the guide sleeve 4, that is, the length of the output shaft 2 and the output shaft sleeve 3 used therewith are different from those in the first embodiment, and the length of the output shaft 2 and the output shaft sleeve 3 can be freely changed within a certain range as required. Figure 2 In the illustrated embodiment 1, one end of the output shaft sleeve 3 passes through the guide sleeve 4; Figure 6 In the second embodiment shown, a portion of one end of the output shaft sleeve 3 is inserted into the guide hole 42; Figure 7 In the third embodiment shown, the output shaft sleeve 3 is suspended above the center of the guide sleeve 4. The length of the spiral hook 5 in the above three embodiments varies with the length of the output shaft sleeve 3, but the relative position of the hook tip of the spiral hook 5 and the housing 1 is consistent, which can always meet the normal operation of the bottle opener.

[0030] The above-described embodiments are specific descriptions of feasible embodiments of the present invention. The description is relatively specific and detailed, but it cannot be understood as limiting the scope of protection of this patent. Any equivalent implementation or modification that does not deviate from the present invention should fall within the scope of protection of this patent.
