Description

Technical Field

[0001] The present invention belongs to the technical field of drinking equipment, and relates to a wine pipe opening and closing mechanism, in particular to a wine pipe opening and closing mechanism for a wine barrel. Background Art

[0002] Beer is a popular beverage among people, especially in summer and often appears in people's lives. Currently, the beer sold on the market is generally filled in bottles or cans. Before drinking, the beer bottle or can needs to be opened and consumed within a short period, otherwise it cannot be sealed and stored, which will affect the taste of the beer.

[0003] Therefore, people have designed a beverage dispensing assembly and a container used in the beverage dispensing assembly, and applied for a Chinese patent (its application number is: 201380069974.9; its publication number is: CN104903230A). The beverage dispensing assembly includes a container, a liquid outlet device having a chamber, a wine pipe, and a liquid outlet valve operating system. Among them, the container is assembled into the chamber, and a first connector for supplying pressurized gas into the container through a gas inlet provided in the container is also provided in the chamber. The liquid outlet valve operating system includes a liquid outlet handle and a valve engagement part connected to a valve in the wine pipe. A bistable spring operating component is provided between the liquid outlet handle and the valve engagement part, so that when the handle moves from the stationary position by more than a predetermined angle, the spring operating component changes position, forcing the engagement part to move from the position of completely closing the valve to the position of completely opening the valve. That is, when the beverage dispensing assembly is in use, the opening and closing of the valve are controlled by operating the liquid outlet handle, and the container is pressurized through the first connector, so that the beverage in the container can be sent out from the valve.

[0004] The bistable spring operating component of the beverage dispensing assembly includes a first leg and a second leg. The first leg and the second leg are both installed on a pivot shaft and can swing around the pivot shaft. The other end of the second leg extends into an opening on the valve engagement part. When the liquid outlet handle swings, it can drive the second leg to swing, and then drive the valve engagement part to translate to open and close the valve. However, during the use of the beverage dispensing assembly, the circumferentially swinging second leg in the shape of a long rod drives the valve engagement part to translate, which easily causes the valve engagement part to shift and get stuck, thus affecting the normal opening and closing of the valve. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems existing in the prior art, and propose a wine pipe opening and closing mechanism, which solves the problem that the existing valve opening and closing control is prone to jamming.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A wine pipe opening and closing mechanism, comprising a housing with an inlet and an outlet, an opening and closing member, a first valve member and a second valve member both in a cylindrical shape. The first valve member is sleeved outside the second valve member, and when they move relative to each other, the inner hole of the second valve member can be blocked. The first valve member is axially fixed in the housing, and the outer end of the first valve member extends out of the outlet. It is characterized in that the outer end of the opening and closing member extends out of the housing, and the inner end thereof has a limiting portion axially fixed to the second valve member. The opening and closing member can drive the second valve member to move along the axis of the second valve member, and a guiding structure capable of guiding the axial movement of the opening and closing member is further provided in the housing.

[0008] The structures of the first valve member and the second valve member in this wine pipe opening and closing mechanism can be the same as the technical solutions in the background art. When this wine pipe opening and closing mechanism is in use, it can be used in cooperation with a wine barrel or a wine stool. The wine pipe of the wine barrel or the wine stool is inserted into the housing through the inlet and communicated with the wine inlet end of the second valve member. During use, the outer end of the opening and closing member can be operated, and the second valve member can be driven to move axially through the opening and closing member. Since the first valve member is axially fixed in the housing, the first valve member will not move axially. When the second valve member moves axially away from the first valve member during the axial movement, the inner hole channel of the second valve member is formed, and the wine liquid can flow out from the wine pipe through the second valve member and the inner hole of the first valve member sleeved outside the second valve member towards the outlet of the housing; on the contrary, when the second valve member moves axially closer to the first valve member during the axial movement, the inner hole of the second valve member is blocked, and the wine liquid cannot flow out.

[0009] During the use of this wine pipe opening and closing mechanism, the second valve member is driven to move axially by operating the opening and closing member. During the movement of the opening and closing member, the axial movement direction can be guided by the guiding structure in the housing, so that the second valve member will not be offset and will not be stuck during the process of being driven by the opening and closing member, and the use stability is good.

[0010] In the above-mentioned wine pipe opening and closing mechanism, the guiding structure includes a long strip-shaped sliding groove axially opened in the housing along the axis of the second valve member and a sliding portion located on the opening and closing member. The sliding portion extends into the sliding groove and can move back and forth along the sliding groove. Through the cooperation of the sliding portion and the sliding groove, the opening and closing member can always move along the axis of the second valve member without being offset, ensuring the stability of use.

[0011] As another case, in the above-mentioned wine pipe opening and closing mechanism, the guiding structure includes a first guiding plane located in the housing, and a second guiding plane is provided at the relative position of the outer side of the opening and closing member and the first guiding plane. The first guiding plane and the second guiding plane are arranged adjacent to each other. By providing the first guiding plane on the inner side of the housing, the first guiding plane is adjacent to the second guiding plane on the outer side of the opening and closing member, avoiding the offset of the opening and closing member during the axial movement and ensuring the stability of use.

[0012] In the above-mentioned wine pipe opening and closing mechanism, both sides of one end of the second valve member facing the opening and closing member have protruding clamping portions, and corresponding to the clamping portions at the inner end of the opening and closing member, there are recessed limiting portions, and the clamping portions are correspondingly clamped into the limiting portions. The two sides of the second valve member are both clamped into the limiting portions, so that when the opening and closing member drives the second valve member to move axially, the force is uniform and the moving direction is stable.

[0013] In the above-mentioned wine pipe opening and closing mechanism, the inner end of the opening and closing member has a semi-circular connecting portion, and both opposite sides inside the connecting portion have the above-mentioned limiting portions. The semi-circular connecting portion can facilitate the installation of the second valve member and also facilitate the clamping portion to be clamped into the limiting portions on both sides.

[0014] In the above-mentioned wine pipe opening and closing mechanism, the side portion of the opening and closing member has an opening for the wine pipe to extend into, and the opening communicates with the inside of the connecting portion. Through the cooperation of the opening and the semi-circular connecting portion, the connection between the wine pipe and the second valve member can be smoother, and the wine liquid flow in the wine pipe can be smoother.

[0015] In the above-mentioned wine pipe opening and closing mechanism, the opening and closing member is rod-shaped and the opening and closing member and the second valve member are arranged coaxially. The coaxial arrangement makes the coaxiality of the two higher during installation and movement, and the movement is more stable.

[0016] In the above-mentioned wine pipe opening and closing mechanism, the side wall of the shell near the outlet has a recessed clamping groove, the outer wall of the first valve member has a protruding clamping portion, and the clamping portion is clamped into the clamping groove. The axial fixation of the first valve member is realized through the cooperation of the clamping portion and the clamping groove, which facilitates connection and disassembly.

[0017] In the above-mentioned wine pipe opening and closing mechanism, a return spring is also sleeved outside the opening and closing member, and both ends of the return spring act on the inner side of the shell and the opening and closing member respectively, so that the opening and closing member has a tendency to move towards the inner end direction. The return spring enables the opening and closing member to drive the second valve member to move and open the inner hole, and then can be conveniently reset to close the inner hole again, avoiding excessive waste of wine liquid flowing out.

[0018] In the above-mentioned wine pipe opening and closing mechanism, the outer end of the opening and closing member is connected with an operating handle, and the operating handle has an opening plane and a closing plane. When the operating handle drives the opening and closing member to open or close the inner hole of the second valve member, the opening plane or the closing plane can respectively abut against the outer surface of the shell. The setting of the opening plane and the closing plane of the operating handle can position the opening position and the closing position of the second valve member, and there is no need to manually maintain the operating state continuously, which is more convenient to use.

[0019] Compared with the prior art, during the use of the wine pipe opening and closing mechanism of the present invention, through the cooperation of the opening and closing member arranged coaxially with the guiding structure, the second valve member always maintains axial movement during the process of being driven by the opening and closing member, avoiding the situation of being stuck due to deviation during the movement process, and the operation and use are more stable.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following are specific embodiments of the present invention in combination with the drawings, and the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0028] Embodiment 1

[0029] As Figure 1 shown, the wine pipe opening and closing mechanism of the present invention includes a housing 1 having an inlet 11 and an outlet 12, an openable valve group arranged in the housing 1, and an opening and closing member 2. Hereinafter, for the convenience of describing the structure and working principle, the structure and principle will be described in the direction shown in the drawings.

[0030] The inlet 11 is located at the rear side of the housing 1, and the outlet 12 is located at the bottom surface of the housing 1. The valve group includes a valve member 1 3 and a valve member 2 4, both of which are vertically arranged and cylindrical. The valve member 2 4 is located above the valve member 1 3, and the upper end of the valve member 1 3 is sleeved on the outer side of the lower end of the valve member 2 4. The valve member 1 3 is axially fixed in the housing 1, and the lower end of the valve member 1 3 extends out of the outlet 12. When the valve member 1 3 and the valve member 2 4 move relative to each other, the inner hole of the valve member 2 4 can be blocked. In this embodiment, the side wall of the housing 1 near the outlet 12 has a concave card groove 15, and the outer wall of the valve member 1 3 has a protruding annular card connection portion 31, and the card connection portion 31 is correspondingly carded into the card groove 15; Figure 5 and Figure 6 As shown, valve component 1 3 includes an outer cylinder 35 located on the outside and an inner cylinder 32 fixed in the outer cylinder 35. The inner cylinder 32 has a plug 33 protruding toward the direction of valve component 2 4. The plug 33 is fixed in the inner cylinder 32 by a plurality of circumferentially distributed connecting ribs 34. When valve component 2 4 moves toward valve component 1 3, the plug 33 can extend into valve component 2 4 and block the inner hole of valve component 2 4, so that the valve group is closed. Conversely, when valve component 2 4 moves in a direction away from valve component 1 3, the plug 33 withdraws from valve component 2 4, the inner hole of valve component 2 4 is connected, and the valve group is opened.

[0031] like Figure 2 and Figure 3 As shown, the opening and closing member 2 is rod-shaped and is coaxially arranged with the valve member 2 4. The outer end of the opening and closing member 2 extends out of the top of the shell 1 and is connected to an operating handle 5. The operating handle 5 has an opening plane and a closing plane. When the operating handle 5 drives the opening and closing member 2 to open or close the inner hole of the valve member 2 4, the opening plane or the closing plane can be respectively abutted against and positioned with the outer surface of the shell 1.

[0032] The inner end of the opening and closing member 2 has a semi-circular connecting portion 24, and the two opposite side walls inside the connecting portion 24 have concave limiting portions 21. The two sides of the end of the valve member 24 facing the opening and closing member 2 have protruding snap-in portions 41, and the snap-in portions 41 are correspondingly snapped into the limiting portions 21 to achieve axial fixation of the opening and closing member 2 and the valve member 24. The side of the inner end of the opening and closing member 2 also has an opening 25 for the wine tube 6 to extend into, and the opening 25 is connected to the inner side of the connecting portion 24. In this embodiment, the outer side of the end of the valve member 24 facing the opening and closing member 2 has the above-mentioned protruding ring-shaped snap-in portion 41, and the limiting portions 21 inside the connecting portion 24 are connected to form a groove.

[0033] In order to ensure that the opening and closing member 2 drives the valve member 2 4 to move axially in a relatively stable and smooth manner, the housing 1 further includes a guide structure that can provide guidance for the axial movement of the opening and closing member 2 .

[0034] In this embodiment, if Figure 4As shown, the guide structure includes a long strip-shaped slide groove 13 opened in the shell 1 along the axial direction of the valve member 24 and a sliding portion 22 protruding from the side of the opening and closing member 2, the sliding portion 22 extends into the slide groove 13 and can move back and forth along the slide groove 13; the guide structure also includes a vertically arranged guide plane 14 located in the shell 1, and a vertically arranged guide plane 23 is provided on the outer side of the opening and closing member 2 opposite to the guide plane 14, and the guide plane 14 and the guide plane 2 23 are adjacent to each other. Here, the number of the guide planes 14 and the number of the guide planes 2 23 are both two and the two guide planes 14 are arranged perpendicular to each other, and the two guide planes 23 and the two guide planes 14 are arranged one by one to prevent the opening and closing member 2 from radially offset during the axial movement.

[0035] The valve group structure composed of valve part 1 3 and valve part 2 4 in the wine pipe opening and closing mechanism is the same as the technical solution in the background art. When the wine pipe opening and closing mechanism is used, it can be used in conjunction with a wine barrel or a wine stool, and the wine pipe 6 of the wine barrel or the wine stool is extended into the housing 1 through the inlet 11 and connected to the upper end of the valve part 2 4 through the opening 25 on the opening and closing part 2.

[0036] When starting to use, the operating handle 5 can be twisted so that the opening plane on the operating handle 5 abuts against and is positioned against the outer surface of the top of the housing 1. During this twisting process, the opening and closing member 2 drives the valve member 2 4 to move axially upward. Since the valve member 1 3 is axially fixed in the housing 1, the valve member 1 3 will not move axially. During the upward axial movement, the valve member 2 4 moves away from the valve member 1 3, and the plug 33 withdraws from the lower end of the valve member 2 4, so that the inner hole of the valve member 2 4 is connected, and the wine flows from the wine tube 6 through the inner hole of the valve member 2 4 and the gap between the connecting ribs in the valve member 2 4 to the valve member 1 3, and flows out from the lower end of the valve member 1 3 for the user to drink.

[0037] On the contrary, the operating handle 5 is moved in the opposite direction, so that the closing plane of the operating handle 5 abuts against and is positioned on the outer side of the top of the housing 1. During this process, the valve member 2 4 moves downward to approach the plug 33, so that the plug 33 extends into the lower end of the valve member 2 4 to seal the inner hole of the valve member 2 4, and the wine stops being delivered immediately.

[0038] Here, in order to make the closing of the valve group faster and more stable, a return spring 7 can be sleeved on the outside of the opening and closing member 2 in the shell 1. The upper end of the return spring 7 abuts against the inner side of the top of the shell 1, and the lower end of the return spring 7 abuts against the opening and closing member 2. Under the elastic force of the return spring 7, the opening and closing member 2 tends to move toward the inner end.

[0039] Embodiment 2

[0040] The solution of this embodiment is basically the same as that of the first embodiment, except that the guide structure only includes the first guide plane 14 and the second guide plane 23 , and does not have the slide groove 13 .

[0041] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
