DETAILED DESCRIPTION OF THE INVENTION

[0026] In order to make the technical means, creative features, achieved objectives and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments and the accompanying drawings. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0027] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0028] As Figures 1 to 8 Shown is a bottle opener with a sound insulation function, including a housing 1. An inflation device 2 is provided on the housing 1. The inflation device 2 includes an inflation member 21 for inserting into the bottle stopper 5 and capable of delivering gas into the bottle body 6. A silencer 3 is provided inside the housing 1, and the silencer 3 has an opening channel 31 for the bottle body 6 to insert. The inflation member 21 can enter the opening channel 31. When the mouth of the bottle body 6 is inserted into the opening channel 31, the opening of the opening channel 31 is closed. A sound insulation channel 32 for noise reduction is provided on the silencer 3. The sound insulation channel 32 has an air outlet end 321 communicating with the outside of the housing 1 and a noise end 322 communicating with the opening channel 31. When the bottle stopper 5 is separated from the bottle body 6, at least part of the gas is subjected to noise reduction treatment through the sound insulation channel 32. In this embodiment, there are two situations. The first is that the mouth of the bottle completely disengages from the opening channel 31. Then, during this process, at least part of the gas enters the sound insulation channel. There is another situation where the bottle stopper 5 is separated from the bottle body 6 but the mouth of the bottle does not disengage from the opening channel 31, and the opening of the opening channel 31 remains sealed. Then all the gas can be discharged from the sound insulation channel. During this process, a large amount of gas energy is consumed, so a good noise reduction effect can be achieved.

[0029] At the moment when the bottle body 6 is separated from the bottle stopper 5, the gas that rushes out instantaneously enters the sound insulation channel 32 from the noise end 322 and is discharged through the air outlet end 321 after noise reduction treatment. During this process, the energy of the gas gradually becomes smaller, thereby achieving noise reduction. Compared with traditional bottle openers, the sound insulation effect is good.

[0030] The sound insulation channel 32 includes at least one main channel 323 in the shape of a Tesla valve channel. The main channel 323 is respectively communicated with the noise end 322 and the air outlet end 321. The direction of the main channel 323 from the noise end 322 to the air outlet end 321 is the reverse of the Tesla valve channel. Using the principle of the Tesla valve channel, the gas energy gradually loses during reverse flow, that is, after entering the sound insulation channel from the opening channel 31, the gas energy gradually loses in the sound insulation channel, thereby achieving the effect of sound insulation and noise reduction. In this embodiment, multiple main channels 323 are provided, and the multiple main channels 323 are arranged in an array on the silencer 3.

[0031] A sound-absorbing channel 32 is provided between the outer wall of the silencer 3 and the inner wall of the housing 1. Sound-absorbing holes 33 are provided on the side wall and / or the top wall of the silencer 3. Both ends of the sound-absorbing holes 33 are respectively communicated with the bottle-opening channel 31 and the sound-absorbing channel 32. The gas enters the noise end 322 of the sound-absorbing channel 32 from the sound-absorbing holes 33 and finally discharges from the air outlet end 321 of the sound-absorbing channel 32. Of course, it is not limited to this method. The sound-absorbing channel 32 can also be arranged on the inner side of the silencer 3, and the noise end 322 of the sound-absorbing channel 32 is located at the bottom, which can also consume the energy of the gas and has a good sound-absorbing effect.

[0032] A gland 13 for fixing the silencer 3 inside the housing 1 is provided at the lower part of the housing 1. A plurality of air outlet holes 131 communicated with the sound-absorbing channel 32 are evenly distributed along the circumferential direction on the end face of the gland 13. The air outlet holes 131 in this embodiment are the above-mentioned air outlet ends 321.

[0033] The sound-absorbing channel 32 further includes a branch channel 324 provided at the bottom of the main channel 323. The branch channel 324 includes a plurality of arc-shaped protrusions 3241 arranged in an array on the outer wall of the silencer 3, and a flow gap is formed between adjacent arc-shaped protrusions 3241. The outer wall of the arc-shaped protrusion 3241 is attached to the inner wall of the housing 1. Through the branch channel 324 for secondary treatment, the winding path can consume the gas energy.

[0034] A positioning cylinder 4 is provided inside the opening of the silencer 3. A plurality of inclined upward annular flaps 41 are arranged at intervals along the axial direction on the inner wall of the positioning cylinder 4. After the bottle mouth is inserted into the positioning cylinder 4, the annular flaps 41 have an elastic restoring force and restore deformation after being pressed to clamp the bottle mouth.

[0035] The silencer 3 is a noise reduction body formed by a sound-absorbing material or a sound-insulating material.

[0036] The inflation device 2 further includes a drive assembly 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 provided in the sealing cavity 25 corresponding to the position of the exhaust hole 232 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. The inflation member 21 is connected to the cylinder base 24 and the inflation member 21 communicates with the sealing cavity 25. The lower end of the inflation member 21 extends into the bottle opening channel 31. The drive assembly 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 6. The inflation device 2 in this embodiment is only a preferred mode and is not limited to this form. The inflation device 2 in the corkscrew patent previously declared by our company is also applicable. The prior application patent uses an inflation cylinder 23 with an air inlet and an air outlet, and one-way valves 26 are provided at the air inlet and the air outlet, only allowing external gas to enter the air cavity 231 from the air inlet and only allowing the gas in the air cavity 231 to enter the wine bottle.

[0037] The drive 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 to the reduction gear set 222. The output end of the reduction gear set 222 is connected to 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 deviated 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. The two ends of the connecting rod 226 are respectively hinged to the eccentric shaft 225 and the piston 233. The corkscrew injects gas into the wine bottle through the inflation device 2, so that the air pressure in the wine bottle increases sharply, forming a reaction force to push out the cork 5.

[0038] In this embodiment, a power supply assembly 7 is further provided inside the housing 1. The power supply assembly 7 includes a circuit board 71 and a battery 72. A button is provided on the circuit board 71. The button, the motor 221, and the battery 72 are respectively electrically connected to the circuit board 71.

[0039] In this embodiment, the housing 1 includes an upper shell 11 and a lower shell 12. An inflation device 2 and a power supply assembly 7 are installed inside the upper shell 11. A silencer 3 is installed inside the lower shell 12. A small hole for the inflation member 21 to enter is provided at the top of the silencer 3. The upper shell 11 includes a first inner cylinder 111 and a first outer cylinder 112. Guide pins are provided on the inner wall of the first inner cylinder 111. The lower cover includes a second inner cylinder 121 and a second outer cylinder 122. A spiral groove 1211 matching with the guide pins is provided at the top of the second inner cylinder 121. During this process, the upper shell 11 and the lower shell 12 move relative to each other, so that the inflation member 21 disengages from the small hole of the silencer 3, and the bottle stopper 5 contacts and disengages from the inner top wall of the silencer 3.
