Description

Technical Field

[0001] The present invention relates to a bottle opener, in particular to a bottle opener for removing the cork of a wine bottle. Background Art

[0002] Now, with the improvement of people's living standards, various fine wines, such as wine and champagne, have gradually entered the household consumption of the general public, and a bottle opener for opening wine bottles is necessarily used.

[0003] CN210214759U discloses a bottle opener, which includes a housing. A film cutting device for cutting the packaging film at the mouth of the wine bottle and an inflation device for injecting gas into the wine bottle are provided on the housing. The inflation device includes a motor, an inflation cylinder and an inflation member. An air chamber is provided in the inflation cylinder. A piston is movably arranged in the air chamber. The piston is in sealing cooperation with the inner wall of the air chamber. An air inlet and an air outlet communicating with the air chamber are further provided on the inflation cylinder. The inflation member is connected to the air outlet of the inflation cylinder. The output shaft of the motor can drive the piston to move in the air chamber to realize the inflation operation of the inflation member on the wine bottle.

[0004] The following problems exist in the above patent: 1. The bottom of the housing is provided with an open mouth, which easily leads to touching the inflation needle and has low safety; 2. When the mouth of the bottle with a diameter smaller than the diameter of the bottle opening channel is inserted, the stability is poor, which easily causes the inflation needle to be skewed and unable to penetrate the cork; 3. When taking the cork, it is necessary to put the hand into the bottle opening channel and a relatively large force is required to pull the cork off the inflation needle, which is highly dangerous. Summary of the Invention

[0005] The object of the present invention: In order to overcome the defects of the prior art, the present invention provides a bottle opener, which is provided with a guide seat in the bottle opening channel, which can play a protective role and enable the inflation needle to be vertically inserted into the cork without deviation. At the same time, a spring for resetting the guide seat is provided to facilitate the removal of the bottle stopper from the inflation needle.

[0006] The technical solution of the present invention: A bottle opener includes a housing and an inflation device arranged in the housing. An opening channel for the bottle body to enter is provided in the housing. The inflation device includes an inflation member for inserting into the bottle stopper and delivering gas into the bottle body. The inflation member is located in the opening channel. A guide seat is slidably arranged along the axial direction of the opening channel in the opening channel and a reset member for resetting the positioning member. A positioning cavity for the bottle body to insert and a through hole communicating with the positioning cavity are provided on the guide seat. The through hole is correspondingly arranged with the inflation member. The inflation member can selectively pass through the through hole and extend into the positioning cavity. When the bottle body is inserted into the positioning cavity and pushed upward, the guide seat moves upward in the opening channel. The inflation member extends into the positioning cavity and penetrates the bottle stopper and inserts into the bottle body to open the bottle. When the bottle body leaves the positioning cavity, the guide seat slides downward towards the bottom of the housing under the action of the reset member. The inflation member exits the positioning cavity. A limit fit is provided between the guide seat and the bottom of the housing to limit the guide seat from detaching from the housing under the action of the reset member.

[0007] With the above technical solution, the bottle body to be uncapped is placed in the positioning cavity and pushed upward. The guide seat slides upward in the uncapping channel, compressing the reset member. At the same time, the inflating member inserts into the bottle stopper. When the guide seat can no longer move upward, the inflating member penetrates through the bottle stopper and enters the bottle body. At this time, the inflating device starts to work, inflating the bottle body, so that the bottle stopper is separated from the platform, realizing uncapping. After uncapping is completed, the bottle body is taken out. At this time, the reset member resets the guide seat, causing the guide seat to slide downward and pushing the bottle stopper remaining on the inflating member to slide downward together, sliding out of the uncapping channel. This facilitates the removal of the bottle stopper without reaching into the uncapping channel, which is more labor-saving. The setting of the guide seat and the through hole ensures good stability when the inflating needle inserts into the bottle stopper and will not deviate, resulting in the inability to inflate the bottle body. When the uncapper is not in use, the guide seat is located at the bottom of the housing, and the inflating member is located above the guide seat, which can play a protective role. Since the end of the inflating member is conically arranged, it is easy to poke and injure, and at the same time, it can also protect the inflating needle from being damaged.

[0008] Further setting of the present invention: The positioning cavity has an inverted bowl-shaped structure, and the caliber from the top to the bottom increases in sequence. The through hole is located at the central position of the top.

[0009] With the above further setting, it can not only be applicable to bottle bodies of different calibers, but also when uncapping, the upper end of the bottle body contacts the inner wall of the positioning cavity, and the bottle body structure is stable, enabling the inflating member to be inserted vertically without deviation.

[0010] Another further setting of the present invention: A limiting boss is provided at the lower end of the uncapping channel on the housing, and a limiting block is provided on the guide seat. The guide seat slides toward the bottom of the housing under the action of the reset member, and the limiting block and the limiting boss are in limiting cooperation to limit the guide seat from detaching from the housing.

[0011] With the above another further setting, after the guide seat is reset under the action of the reset member, the limiting block is placed on the limiting boss to prevent the guide seat from detaching from the housing, and at the same time, it will not prevent the sliding of the guide seat, which can play a better protective role.

[0012] Another even further setting of the present invention: A plurality of guide strips are provided on the inner side wall of the housing along its vertical direction, corresponding guide grooves are provided on the guide seat, and the guide strips and the guide grooves cooperate to realize the sliding of the guide seat.

[0013] With the above another even further setting, it plays a guiding role, making the structure of the guide seat stable when sliding.

[0014] Further improvement of the present invention: The housing is divided into a first cavity and a second cavity by a partition along its vertical direction. The inflation device is arranged in the first cavity. The inflation device further includes a driving assembly, an inflation cylinder, and a cylinder base. A sealing cavity is formed between the cylinder base and the inflation cylinder. The inflation cylinder is provided with an air cavity, and an exhaust hole is arranged at the bottom of the air cavity. A one-way valve is arranged in the sealing cavity corresponding to the position of the exhaust hole to make the fluid flow unidirectionally from the air cavity to the sealing cavity. A piston is movably arranged in the air cavity, and the piston is in sealing cooperation with the inner wall of the air cavity. A concave cavity is arranged on the partition, and the lower end of the cylinder base is located in the concave cavity. The upper end of the inflation part extends into the cylinder base and communicates with the sealing cavity. The lower end part of the inflation part extends into the first cavity. The driving assembly can drive the piston to move in the air cavity to realize the inflation operation of the inflation part on the bottle body. The second cavity is hollow to form the bottle-opening channel.

[0015] With the above further improvement, the structural layout is reasonable and the sealing performance is good, making the gas flow in only one direction, allowing only external gas to enter the air cavity, and also allowing only the gas in the air cavity to enter the bottle body.

[0016] Further improvement of the present invention: The upper end part of the guide seat is provided with a positioning groove, the lower end surface of the partition is provided with a positioning post, and the positioning post is provided with a notch for the inflation part to pass through. The reset part is arranged as a reset spring. The upper end of the reset spring is sleeved on the positioning post, and the lower end is arranged in the positioning groove.

[0017] With the above further improvement, the structure of the reset spring is stable, and the guide seat can be reset better.

[0018] Further improvement of the present invention: The driving assembly includes a motor, a reduction gear set, a first bevel gear, a second bevel gear, an eccentric shaft, and a connecting rod. The output end of the motor is connected with the reduction gear set. The output end of the reduction gear set is connected with the first bevel gear. The second bevel gear is rotatably connected to the inner wall of the housing and meshes with the first bevel gear to form a linkage. The eccentric shaft is arranged at a position deviating from the center of the second bevel gear, and the eccentric shaft is parallel to the central axis of the second bevel gear. One end of the connecting rod is hinged to the eccentric shaft, and the other end is connected to the piston.

[0019] With the above further improvement, the output shaft of the motor can drive the first bevel gear to rotate through the reduction gear set. The first bevel gear meshes with the second bevel gear to form a linkage, which can drive the eccentric shaft to move eccentrically, thereby driving the piston to reciprocate in the air cavity, injecting gas into the wine bottle, causing the air pressure in the wine bottle to increase sharply, forming a reaction force to push out the cork. The structure is simple and the transmission is stable.

[0020] A further improvement of the present invention is as follows: A power supply assembly is also provided inside the housing. The power supply assembly includes a first circuit board, a second circuit board, and a power supply. A charging port is provided on the first circuit board, and a control switch for controlling the operation of the motor is provided on the second circuit board. The second circuit board, the power supply, and the motor are all electrically connected to the first circuit board.

[0021] With the above further improvement, a button is provided on the outer side of the housing corresponding to the position of the control switch. Pressing the button conducts the circuit, thereby driving the motor to operate. There are two power supplies, which are respectively located on both sides of the motor. The structure is compact and the battery capacity is large. Description of the Drawings

[0033] Such as Figure 1-7As shown in the figure, a bottle opener includes a housing 1 and an inflation device 2 disposed within the housing 1. The housing 1 is provided with an opening channel 11 for a bottle body 10 to enter. The inflation device 2 includes an inflation member 21 for inserting into a bottle cork 20 and capable of delivering gas into the bottle body 10. The inflation member 21 is located within the opening channel 11. A guide seat 3 is slidably disposed along the axial direction within the opening channel 11, and a reset member 4 is provided for resetting and positioning the member 3. The guide seat 3 is provided with a positioning cavity 31 for the bottle body 10 to be inserted and a through hole 32 communicating with the positioning cavity 31. The through hole 32 is correspondingly disposed with the inflation member 21. The inflation member 21 can selectively pass through the through hole 32 and extend into the positioning cavity 31. When the bottle body 10 is inserted into the positioning cavity 31 and pushed upward, the guide seat 3 moves upward within the opening channel 11, the inflation member 21 extends into the positioning cavity 31, and passes through the bottle cork 20 and inserts into the bottle body 10 to open the bottle. When the bottle body 10 disengages from the positioning cavity 31, the guide seat 3 slides downward toward the bottom of the housing 1 under the action of the reset member 4, and the inflation member 21 withdraws from the positioning cavity 31. The guide seat 3 and the bottom of the housing 1 are in a limiting fit to prevent the guide seat 3 from disengaging from the housing 1 under the action of the reset member 4. The bottle body 10 to be opened is placed into the positioning cavity 31 and pushed upward. The guide seat 3 slides upward within the opening channel 11, compressing the reset member 4. At the same time, the inflation member 21 inserts into the wooden cork 20. When the guide seat 3 can no longer move upward, the inflation member 21 penetrates through the bottle cork 20 and enters the bottle body 10. At this time, the inflation device 2 starts to operate to inflate the bottle body 10, causing the bottle cork 20 to disengage from the platform and achieving bottle opening. After bottle opening is completed, the bottle body 10 is taken out. At this time, the reset member 4 resets the guide seat 3, causing the guide seat 3 to slide downward and pushing the bottle cork 20 remaining on the inflation member 21 to slide downward together, sliding out of the opening channel 11. This facilitates the removal of the wooden cork without the need to reach into the opening channel, which is more labor-saving. The setting of the guide seat and the through hole ensures good stability when the inflation needle inserts into the wooden cork and prevents deviation, which may cause the inability to inflate the bottle body. When the bottle opener is not in use, the guide seat is located at the bottom of the housing, and the inflation member is located above the guide seat, which can provide protection. Since the end of the inflation member is tapered, it is easy to cause stabbing injuries, and at the same time, it can protect the inflation needle from damage. On the inner side wall of the housing 1, a plurality of guide strips 13 are provided along the vertical direction. Corresponding guide grooves 34 are provided on the guide seat 3. There are at least two guide grooves 34, which are symmetrically arranged with the through hole as the center. The guide strips 13 cooperate with the guide grooves 34 to realize the sliding of the guide seat 3, playing a guiding role and ensuring the stable structure of the guide seat 3 during sliding.

[0034] The positioning cavity 31 has an inverted bowl-shaped structure, and the diameter of the top of the positioning cavity 31 increases sequentially from the top to the bottom. The through hole 32 is located at the center of the top. When opening bottles of different diameters, it can ensure that the inflation needle penetrates through the cork. The sequentially increasing diameter can not only be applicable to bottles of different diameters, but also when opening the bottle, the upper end of the bottle contacts the inner wall of the positioning cavity, and the bottle structure is stable, so that the inflation member can be vertically inserted without deviation. A limiting boss 12 is provided at the lower end of the opening channel 11 on the housing 1, and a limiting block 33 is provided on the guiding seat 3. The guiding seat 3 slides towards the bottom of the housing 1 under the action of the reset member 4, and the limiting block 33 and the limiting boss 12 are in limiting cooperation to limit the guiding seat 3 from detaching from the housing 1. After the guiding seat 3 is reset under the action of the reset member 4, the limiting block 33 is placed on the limiting boss 12 to prevent the guiding seat 3 from detaching from the housing 1, and at the same time, it will not prevent the sliding of the guiding seat 3, which can play a better protective role.

[0035] The housing 1 is divided into a first cavity 15 and a second cavity 16 along its vertical direction by a partition 14. The inflation device 2 is arranged in the first cavity 15. The inflation device 2 further includes a driving component 22, an inflation cylinder 23 and a cylinder base 24. A sealing cavity 25 is formed between the cylinder base 24 and the inflation cylinder 23. An air cavity 231 is provided in the inflation cylinder 23, and an exhaust hole 232 is provided at the bottom of the air cavity 231. A one-way valve 26 is arranged in the sealing cavity 25 corresponding to the position of the exhaust hole 231 to make the fluid direction unidirectionally conduct from the air cavity 231 to the sealing cavity 25. A piston 233 is movably arranged in the air cavity 231, and the piston 233 is in sealing cooperation with the inner wall of the air cavity 231, and a sealing member 234 is used to achieve the sealing cooperation. A concave cavity 141 is provided on the partition 14, and the lower end of the cylinder base 24 is located in the concave cavity 141. The upper end of the inflation member 21 extends into the cylinder base 24 and communicates with the sealing cavity 25. The lower end of the inflation member 21 extends into the first cavity 15. The driving component 22 can drive the piston 233 to move in the air cavity 231 to realize the inflation operation of the inflation member 21 on the bottle body 10. The second cavity 16 is hollow to form the opening channel 11. The structural layout is reasonable and the sealing performance is good, so that the gas can only flow in one direction. The external gas enters the air cavity and then enters the bottle body from the air cavity. The inflation device 2 in this embodiment is only a preferred method and is not limited to this form. The inflation device 2 in the bottle opener patent previously applied by the company is also applicable. The previously applied patent uses an inflation cylinder 23 with an air inlet and an air outlet, and one-way valves 26 are arranged at the air inlet and the air outlet, allowing only the external gas to enter the air cavity 231 from the air inlet and allowing only the gas in the air cavity 231 to enter the wine bottle.

[0036] A positioning groove 35 is provided at the upper end of the guiding seat 3. A positioning post 142 is provided on the lower end surface of the partition plate 14. A notch for the inflation member 21 to pass through is provided on the positioning post 142. The reset member 4 is arranged as a reset spring. The upper end of the reset spring is sleeved on the positioning post 142, and the lower end is arranged in the positioning groove 35, so that the structure of the reset spring is stable and the guiding seat can be reset better.

[0037] The driving assembly 22 includes a motor 221, a reduction gear set 222, a first bevel gear 223, a second bevel gear 224, an eccentric shaft 225 and a connecting rod 226. The output end of the motor 221 is connected with the reduction gear set 222. The output end of the reduction gear set 222 is connected with the first bevel gear 223. The second bevel gear 224 is rotatably connected to the inner wall of the housing 1 and meshes with the first bevel gear 223 to form a linkage. The eccentric shaft 225 is arranged at a position deviating from the center of the second bevel gear 224 and the eccentric shaft 225 is parallel to the central axis of the second bevel gear 224. One end of the connecting rod 226 is hinged to the eccentric shaft 225, and the other end is connected with the piston 233. The output shaft of the motor 221 can drive the first bevel gear 223 to rotate through the reduction gear set 222. The first bevel gear 223 and the second bevel gear 224 mesh to form a linkage, which can drive the eccentric shaft 225 to move eccentrically, thereby driving the piston 233 to reciprocate in the air chamber 231, injecting gas into the wine bottle 10, so that the air pressure in the wine bottle 10 increases sharply, forming a reaction force to push out the cork. The structure is simple and the transmission is stable.
