DETAILED DESCRIPTION OF THE INVENTION

In order to make the purpose, technical solutions, and advantages of the present invention clearer, the following further describes the present invention with reference to the accompanying drawings and detail embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not used to limit the present invention.

In order to illustrate the technical solutions of the present invention, detail embodiments are described below.

Referring to FIGS. 1-9, a bottle opener provided in accordance with an embodiment of the present invention comprises: a bottom cover 2, an inflating device 1, and a shell 3 sheathed outside the inflating device. The inflating device 1 comprises: an inflating needle 7, an inner inflating tube 4, a valve plug assembly 6, and an outer inflating tube 5 sleeved outside the inner inflating tube. The valve plug assembly 6 comprises: a valve plug base 16, a valve plug 17 and a valve plug stopper 18. The valve plug base 16 is connected with the valve plug stopper 18, forms the first chamber 23. The valve plug 17 is disposed in the first chamber 23. An outer wall of the head end of the inner inflating tube 4 is sleeved with a piston ring 8, and an outer wall of the end of the inner inflating tube 4 is fitted in a stop component 9 which is used for limiting the movement of the outer inflating tube 5. The inner inflating tube 4 defines the first through hole 10, and the inflating needle 7 is fixed in and pass through the first through hole 10. The bottom cover 2 and the shell 3 can be connected.

In the embodiment of the present invention, the inner inflating tube 4 defines the second chamber 11. The outer inflating tube 5 and the inner inflating tube 4 can be connected at the stop component 9 to define a third chamber 12 therebetween. The head end of the inner inflating tube 4 therein is equipped with the valve plug assembly 6 which can be used for closing the second chamber 11 to prevent air from flowing out, and the stop component 9 is embedded in the outer wall of the inner inflating tube 4.

In the embodiment of the present invention, the stop component 9 is a cylinder and forms an externally-threaded cylinder 13 at the end thereof, and the bottom cover 2 is fitted therein with an internal-threaded groove 14 which is coupled to the externally-threaded cylinder 13 of the stop component. The outer wall of the head end of the inner inflating tube 4 forms an annular groove 15 and the piston ring 8 is fitted in the annular groove 15. The piston ring 8 is sleeved in the annular groove 15. When the space between the inner inflating tube 4 and the outer inflating tube 5 is compressed, air pressure in the space is increased, the piston ring 8 is used to tightly fit on to seal the outer wall of the inner inflating tube 4.

In the embodiment of the present invention, the valve plug assembly 6 includes a valve plug base 16, a valve plug 17, and a valve plug stopper 18. The inner wall of the head end of the inner inflating tube 4 therein defines a first limiting groove 19 for limiting the valve plug base 16. The function of the valve plug assembly 6 is that: when pressing the outer inflating tube 5 of the inflating device 1 for inflation, the valve plug opens thus air enters the wine bottle through the inflating needle. When the outer inflating tube of the inflating device is pulled off, the valve plug moves to the valve plug base until the valve plug 17 tightly fits on and seals the tapered inner wall in the valve plug base, so that air cannot flow out.

In the embodiment of the present invention, the valve plug base 16 has a second through hole 24, and the inner wall of the valve plug base 16 is provided with a step 22 that is used for engaging with the valve plug stopper 18. One end of the stopper 18 forms a protrusion 25, and the protrusion 25 forms lateral openings 26. The shape of the valve plug 17 is conical.

In the embodiment of the present invention, the inner wall of the head end of the inner inflating tube 4 is provided with a first limiting groove 19 for limiting the valve plug base 16.

In the embodiment of the present invention, the outer inflating tube 5 is embedded in the shell 3 and form a second limiting groove 20, and movably matches with the stop component 9.

In the embodiment of the present invention, the bottom cover 2 defines a fourth chamber 21 therein for accommodating the inflating needle 7, and the fourth chamber 21 is used for accommodating the inflating needle 7 to protect the inflating needle from being exposed to hurt the user or cause other disadvantages.

In the embodiment of the present invention, the bottom cover 2 and the shell 3 are made of wood materials, which improves the appearance of the bottle opener.

The working process of the bottle opener provided in the embodiment of the present invention is as follows:

when in use, pulling the outer inflating tube, the air pressure in the inner inflating tube and the inflating needle becomes in a negative pressure state; and the valve plug moves to fit against the valve plug base. When pressing the outer inflating tube 5, the space between the inner inflating tube and the outer inflating tube is compressed, the air pressure in the space is increased, the piston ring 8 can tightly fit and seal the tube walls between the inner inflating tube; the air flows into the inflating needle through the inner inflating tube and air is continuously input into the wine bottle. As the air pressure in the wine bottle being increased, the cork will be pushed upward under the action of air pressure; finally, the cork can be pulled out under the air pressure in the wine bottle, and an integrate and unbroken cork can be easily obtained.

When not in use, inserting the head of the inflating needle into the fourth chamber of the bottom cover, and the cylinder of the stop component of the inflating device and the groove of the bottom cover are screwed to facilitate carrying.

In accordance with the embodiments of the present invention, the bottle opener pulls out a wooden cork of the wine bottle by means of air pressure, thereby effectively protecting the integrity of the wooden cork and improving the sealing performance of the wooden cork during repeated use. The bottle opener is convenient to carry and avoids hurting the user so as to provide a saft protection.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included within the scope of the present invention.
