Description

Technical Field

[0001] The invention belongs to the technical field of drinking equipment and relates to a beer dispenser. Background Art

[0002] With the continuous improvement of people's living standards, beer has become an indispensable drink in people's daily leisure activities or business activities. At the same time, people have higher requirements for the way of drinking beer. More and more people prefer to drink hygienic, fresh and delicious pure draft beer. The draft beer on the market is packed in barrels and then dispensed by special machines or devices. However, the traditional dispensing machines or dispensing devices are large in size and are basically only used in fixed places such as bars and restaurants. They cannot be used portable, especially outdoor.

[0003] To this end, China Patent has disclosed a beer keg air pressure valve with application number 93231183.0, which consists of an air pressure mechanism and a beer dispensing mechanism. The air pressure mechanism consists of a valve seat with a connector that can be fastened to the beer keg, a sealing ring placed under the valve seat and embedded in the middle of the beer keg upper cover, an air bag installed on the valve seat, an air bag cover installed on the upper edge of the air bag, a sealing cover with an annular groove installed in the central hole of the air bag cover, a sealing ring installed in the annular groove of the sealing cover, a spring installed between the sealing cover and the valve seat, and a spring installed in the valve seat. The seat is composed of a shield with a hole in the middle part, which is sleeved on the outside of the airbag and the airbag cover, and a pressure cover with a pressure column in the middle, which is installed in the middle hole of the shield and located on the airbag cover. The valve seat has a vertical hole in the center with an opening facing downward, and a horizontal hole on its side with an opening facing outward and communicating with the vertical hole. The vertical hole on the valve seat also has ventilation holes opening on the upper and lower sides of the valve seat. The beer discharging mechanism is composed of a conduit with one end inserted into the beer barrel and the other end inserted into the vertical hole of the valve seat, and a curved pipe with one end extending out of the beer barrel and the other end inserted into the horizontal hole. The beer barrel air pressure valve integrates the beer discharging and pressurizing functions, can be used in a portable manner, and is particularly convenient for users to drink beer in outdoor places.

[0004] However, the beer keg air pressure valve also has obvious defects: beer contains foam, and when the beer is dispensed, the foam will flow through the conduit and the elbow together with the beer, and some foam will adhere to the inner wall of the conduit, the elbow and the inner hole of the valve seat, which will easily breed bacteria over time and lead to poor hygiene. In view of this situation, people usually replace the beer keg air pressure valve with a new one. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems existing in the prior art and to propose a beer dispenser, which solves the problems of being unhygienic and easy to breed bacteria after long-term use.

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

[0007] A beer dispenser comprises a cylindrical body, wherein a boosting chamber capable of achieving boosting through volume change is provided on the upper portion of the body, and the character is characterized in that a core assembly is connected to the bottom of the body, the core assembly is an integrated structure or is fixedly connected as a whole, an air inlet channel and a beer outlet channel are provided on the core assembly, and a mounting cavity for inserting the core assembly into the body is provided at the bottom of the body, the core assembly is inserted into the mounting cavity so that the inlet of the air inlet channel is connected with the boosting chamber, the core assembly and the body are positioned axially by a clamping structure, the mounting cavity runs through the side of the body, and the outlet of the beer outlet channel is provided on the side of the core assembly and extends out of the side of the body through the mounting cavity.

[0008] When in use, the body is fixed to the beer spear on the top of the barrel, and the core assembly is provided with an air inlet channel and a wine outlet channel extending out of the side of the body, so that the beer dispenser can cooperate with the barrel to distribute beer by relying on a single core assembly. Specifically, the barrel is inflated by the core assembly (the volume change of the boost chamber is controlled to increase pressure), and then the wine in the barrel flows out of the body through the wine outlet channel under the action of pressure for distribution for people to drink. Since the core assembly is connected to the body through the clamping structure along the axial direction, a detachable connection is formed between the core assembly and the body, and the wine outlet channel extends out of the side of the body through the installation cavity, so that the core assembly can be installed and disassembled independently. In this way, after a long period of use, the user can replace the core assembly to ensure that the beer dispenser can maintain good hygiene and avoid bacteria during continuous use. In addition, the beer dispenser only needs to replace the core assembly to ensure hygiene, and the body and other components can be recycled, so the cost is reduced compared to replacing the entire beer dispenser.

[0009] In the above-mentioned beer dispenser, the core assembly includes a main body and a tubular wine outlet portion arranged on the side of the main body, and the wine outlet channel includes a wine inlet section arranged on the main body and a wine outlet section arranged in the wine outlet portion in sequence, and the wine outlet portion extends out of the side of the main body.

[0010] The arrangement of the beer outlet allows the beer outlet channel to extend out of the outer side of the main body, so that the beer dispenser can complete the complete beer distribution by relying solely on the core assembly, thereby ensuring that the beer dispenser remains hygienic and prevents bacteria from growing when only the core assembly is replaced.

[0011] In the above-mentioned beer dispenser, the side portion of the main body has an interface, and one end of the beer dispensing portion is inserted into the interface to be fixed, or the beer dispensing portion is integrally formed on the side portion of the main body.

[0012] Whether one end of the beer dispensing portion is inserted into the interface and fixed therein or the beer dispensing portion is integrally formed on the side of the main body, the core assembly can be detachably connected to the main body as a whole, so that the beer dispenser can ensure hygiene by directly replacing the core assembly.

[0013] In the above-mentioned beer dispenser, the installation cavity includes a clearance notch running through the bottom and side of the main body and a connecting hole connected to the clearance notch. The upper end of the main body is clamped in the connecting hole, and the beer outlet is located at the clearance notch.

[0014] The installation cavity is formed by the connection hole and the clearance notch, so that the core component can be installed and disassembled on the body without restriction.

[0015] In the above-mentioned beer dispenser, the installation cavity also includes a mounting hole connected to the lower end of the connecting hole, and a plurality of snap-fitting protrusions are evenly distributed along the circumference at the lower end of the mounting hole, and the clearance gap is connected to the mounting hole and is located between two adjacent snap-fitting protrusions.

[0016] The mounting hole is sleeved outside the wine spear of the wine barrel, and the body and the wine barrel are fixed when in use by the clamping convex edge clamping with the wine spear. The mounting hole is connected with the lower end of the connecting hole, and the clearance gap is connected with the mounting hole and is located between two adjacent clamping convex edges, so that the core assembly can be installed and removed without being restricted by the clamping convex edges.

[0017] In the above-mentioned beer dispenser, an air intake connector is provided in the main body, one end of which is connected to the pressurization chamber, the inlet of the air intake passage is provided at the top of the main body, and the other end of the air intake connector is inserted into the top of the main body.

[0018] The air intake joint connects the boost chamber with the air intake channel on the core assembly, so that the boost chamber can inflate the air into the air intake channel through the change of volume, thereby increasing the pressure in the wine barrel to utilize the core assembly to automatically discharge wine.

[0019] In the above-mentioned beer dispenser, the snap-fit ​​structure is an elastic snap-fit ​​structure, and an ejector is slidably arranged in the body. The ejector includes a rod body and a pressing head fixedly connected to one end of the rod body, and the other end of the rod body extends out of the body. An inclined guide surface is provided on the pressing head. When the ejector slides, the guide surface can push the core assembly to overcome the action of the elastic snap-fit ​​structure and disengage from the body.

[0020] The elastic buckle structure enables the core assembly to be firmly connected to the body during use, ensuring the stability of use. When the core assembly needs to be replaced, just press the ejector, and the guide surface on the ejector will push the core assembly to overcome the elastic buckle structure and directly disengage from the body. Then the user only needs to remove the core assembly from the body and replace it with a new one, so that the beer dispenser can be better maintained in hygiene and avoid bacterial growth during continuous use. Moreover, the use of the elastic buckle structure and the ejector allows the user to easily disassemble the core assembly.

[0021] In the above-mentioned beer dispenser, the outer side of the main body of the core assembly has an annular fitting portion, the top pressure head is U-shaped, and the above-mentioned guide surfaces are provided at both ends of the top pressure head, and the guide surfaces can move along the fitting portion when the ejector slides.

[0022] The U-shaped top pressure head cooperates with the annular matching part, so that the core assembly is subjected to more even force, ensuring that the user can stably disassemble and replace the core assembly.

[0023] In the above-mentioned beer dispenser, the main body is provided with a U-shaped pin inserted from the side, and the clamping structure includes a slot symmetrically arranged on the outside of the main body of the core assembly and two rods of the U-shaped slot, and the two rods of the U-shaped pin are inserted into the two slots.

[0024] Inserting the U-shaped latch can fix the core assembly to the body. Pulling out the U-shaped latch can disengage the core assembly from the body so that the user can directly remove the core assembly from the body.

[0025] In the above-mentioned beer dispenser, an extension tube is provided outside the beer outlet, and the beer outlet can be opened or closed when the extension tube slides. A handle is provided outside the body, and the middle part of the handle is hinged to the body. An annular bayonet is provided on the outer side of the extension tube, and the lower end of the handle is a U-shaped clamping part that is clamped into the annular bayonet.

[0026] The user operates the handle to swing, so that the clamping part can drive the extension tube to slide, thereby controlling whether the wine outlet channel discharges wine. In this way, the beer dispenser can realize the autonomous control function of liquid discharge. At the same time, the clamping part is clamped in the annular bayonet from top to bottom, which enables the clamping part to drive the extension tube to slide, and at the same time the extension tube is not restricted to the main body by the clamping part. The extension tube cooperates with the core assembly to form a whole. When the core assembly is disassembled from the main body, the extension tube can be removed together, ensuring that the beer dispenser can maintain good hygiene and avoid bacterial growth during continuous use. It is also very convenient for replacement.

[0027] Compared with the prior art, the present beer dispenser relies on a single core assembly to cooperate with the wine barrel to dispense beer. Since the core assembly is connected to the main body along the axial direction through a clamping structure, a detachable connection is formed between the core assembly and the main body, and the beer outlet channel extends out of the side of the main body through the installation cavity, so that the core assembly can be installed and disassembled independently. In this way, after a long period of use, the user can replace the core assembly to ensure that the beer dispenser can maintain better hygiene and avoid bacterial growth during continuous use.

[0028] In addition, the beer dispenser only needs to replace the core assembly to ensure hygiene, and the body and other components can be recycled, thereby reducing costs compared to replacing the entire beer dispenser. BRIEF DESCRIPTION OF THE DRAWINGS

The wine outlet channel 2b includes a wine inlet section 2b1 provided on the main body 2c and a wine outlet section 2b2 provided in the wine outlet section 2d in sequence. The inlet of the wine inlet section 2b1 is provided at the bottom of the main body 2c, and the outlet of the wine inlet section 2b1 is provided at the side of the main body 2c and communicates with the wine outlet section 2b2. The inlet of the air inlet channel 2a is provided at the top of the main body 2c and the outlet of the air inlet channel 2a is provided at the lower end side of the main body 2c. The side of the main body 2c has an interface 2c1, and the wine outlet 2d is inserted into the interface 2c1 to be fixed. Of course, the wine outlet 2d can also be integrally formed on the side of the main body 2c. The mounting cavity 4a includes a clearance notch 4a2 that runs through the bottom and side of the main body 1 and a connecting hole 4a1 that is connected to the clearance notch 4a2. The upper end of the main body 2c is clamped in the connecting hole 4a1, and the wine outlet 2d is located at the clearance notch 4a2. The mounting cavity 4a also includes a mounting hole 4a3 connected to the lower end of the connection hole 4a1, and a plurality of snap-fitting convex edges 4b are evenly distributed along the circumferential direction at the lower end of the mounting hole 4a3, and the clearance gap 4a2 is connected to the mounting hole 4a3 and is located between two adjacent snap-fitting convex edges 4b. An air intake connector 5 is provided in the body 1, and the upper end of the air intake connector 5 is connected to the supercharging cavity 1a, and the other end of the air intake connector 5 is inserted into the top of the body 2c.

[0042] The beer dispenser can be used for distributing beer. When installing, the installation hole 4a3 is put on the outside of the beer spear on the wine barrel, and the main body 1 is rotated to make each clamping convex edge 4b ​​and the beer spear rotate and clamp, so that the main body 1 and the beer spear are installed and fixed. At the same time, the lower end of the main body 2c of the core component 2 is inserted into the wine barrel to open the air path and the beer path, so that the beer dispenser can inflate the wine barrel through the core component 2, and make the beer in the wine barrel flow out of the main body 1 through the wine outlet channel 2b of the core component 2 under pressure for distribution.

[0043] like Figure 1 and Figure 3As shown, the outer sleeve of the wine outlet 2d is provided with an extension tube 12, and a blocking structure is provided between the inner hole of the extension tube 12 and the wine outlet 2d, which can control the connection or disconnection between the two when the extension tube 12 slides. A handle 14 is provided on the outside of the main body 1, and the middle part of the handle 14 is hinged to the main body 1. An annular bayonet 12a is provided on the outside of the extension tube 12, and the lower end of the handle 14 is a U-shaped clamping part 14a that is clamped into the annular bayonet 12a. The blocking structure includes a plug 13, and a positioning sleeve is fixed in the extension tube 12. The plug 13 is located on the inner side of the positioning sleeve and the two are fixedly connected by a number of connecting strips. The inner hole of the wine outlet 2d is the wine outlet section 2b2, and the inner diameter of the outer port of the wine outlet 2d is smaller than the diameter of the inner hole of the wine outlet tube 3. When the extension tube 12 slides, the plug 13 can be blocked in the outer port of the wine outlet tube 3 or inserted into the inner hole of the wine outlet tube 3.

[0044] like Figure 1 and Figure 2 As shown, the main body 1 includes a cylindrical shell 3, the top and bottom of the shell 3 are both open, and a circular partition 3a is fixedly connected to the inner wall of the middle part of the shell 3. A piston 9 and a support spring 10 are arranged in the top opening of the shell 3. The upper end of the piston 9 extends out of the upper end of the shell 3 under the elastic force of the support spring 10. A boosting chamber 1a is formed between the piston 9 and the upper inner cavity of the shell 3, and a lock cap 11 is externally threadedly connected to the upper port of the shell 3 to prevent the piston 9 from being disengaged from the shell 3. This structure makes the upper part of the main body 1 form a structure similar to that of a traditional air pump. In addition to manual air pumping, the action mode of the piston 9 can also be set to electric control. The main body 1 also includes a base 4 fixed in the bottom opening of the shell 3 by fasteners, and the installation cavity 4a is arranged on the base 4. An annular shoulder 5a is arranged on the outer side of the air inlet joint 5, and the annular shoulder 5a is fixed between the circular partition 3a and the top of the base 4. A boss 3b is fixedly connected at the center of the upper surface of the circular partition 3a, and an air guide hole 3b1 is provided on the boss 3b. The upper end of the air inlet joint 5 is inserted into the air guide hole 3b1. A plurality of air holes 3b2 are provided through the upper end surface of the boss 3b. A sealing valve plate 6 that can move up and down is provided in the air guide hole 3b1. When the sealing valve plate 6 moves upward, each of the air holes 3b2 can be blocked. In this embodiment, a core rod 6a is fixedly connected to the center of the sealing valve plate 6. The core rod 6a passes through the center of the upper end surface of the boss 3b. The outer side of the portion of the core rod 6a that passes through the boss 3b is provided with a blocking portion that can abut against the upper end surface of the boss 3b. The setting of the sealing valve plate 6 forms a one-way connection between the air intake channel 2a and the boost chamber 1a. When the piston 9 is pressed to inflate, the air pressure pushes the sealing valve plate 6 downward to open the air holes 3b2; when the piston 9 is returned to its original position by the support spring 10, the gas pumped into the wine barrel will flow back, thereby pushing the sealing valve plate 6 upward and closing each air hole 3b2, ensuring that no air leakage occurs and ensuring the stability of inflation.

[0045] like Figure 4 , Figure 6 and Figure 7As shown, the core assembly 2 and the body 1 are connected axially through a snap-fit ​​structure provided between the upper end of the main body 2c of the core assembly 2 and the inner wall of the connecting hole 4a1. In this embodiment, the snap-fit ​​structure is an elastic snap-fit ​​structure. The outer side of the upper end of the main body 2c has a matching portion 2c2, which is annular, and the outer side of the main body 2c has an annular surface. The lower end of the matching portion 2c2 is fixedly connected to the annular surface, and a gap is formed between the matching portion 2c2 and the outer wall of the upper end of the main body 2c. The interface 2c1 is fixedly connected to the matching portion 2c2. The base 4 has an annular body 4c on the inner side of the connecting hole 4a1, the upper end of the main body 2c is inserted into the annular body 4c and the matching portion 2c2 is inserted into the connecting hole 4a1, and the elastic snap-fit ​​structure is provided between the matching portion 2c2 and the connecting hole 4a1. Specifically, the elastic buckle structure includes a bayonet 2c21 disposed on the outer side of the matching portion 2c2 and an elastic block 4d located on the inner wall of the connecting hole 4a1, the elastic block 4d is inserted into the bayonet 2c21, and the two opposite side walls of the elastic block 4d are inclined and inclined in opposite directions. In addition to the above method, the positions of the bayonet 2c21 and the elastic block 4d can also be interchanged.

[0046] Furthermore, if Figure 5 , Figure 6 and Figure 7 As shown, two right-angled notches 4e are symmetrically arranged on the outer side of the upper end of the base 4, and the two right-angled notches 4e are connected to the connecting hole 4a1, and the top of the matching portion 2c2 is located at the right-angled notch 4e. An ejector 7 is slidably arranged in the body 1, and the ejector 7 includes a rod body 7a and a top pressure head 7b fixed to one end of the rod body 7a, and the other end of the rod body 7a extends out of the body 1. The top pressure head 7b is U-shaped, and the two ends of the top pressure head 7b are located at the two right-angled notches 4e. The lower surfaces of the two ends of the two top pressure heads 7b are provided with guide surfaces 7b21. When the ejector 7 slides, the guide surfaces 7b21 can move along the matching portion 2c2 so that the ejector 7 pushes the core assembly 2 to overcome the effect of the elastic buckle structure and disengage from the body 1. The upper end of the main body 2c is inserted into the base 4 and fixed to the base 4 through an elastic snap-fit ​​structure. When the core assembly 2 needs to be replaced, the user can push the ejector 7 from the outside to the inside. When the ejector 7 moves, the guide surface 7b21 will move along the matching portion 2c2, thereby exerting a downward thrust on the core assembly 2, so that the core assembly 2 can overcome the effect of the elastic snap-fit ​​structure and disengage from the main body 1.

[0047] like Figure 7 , Figure 8 and Fig. 9As shown, the lower surface of the circular partition 3a is fixedly connected to a spring seat 3c, the inner end of the rod body 7a is fixedly connected to a baffle 7c, the top pressure head 7b is fixedly connected to the baffle 7c, and a return spring 8 is provided inside the spring seat 3c. The two ends of the return spring 8 are respectively against the spring seat 3c and the baffle 7c. The ejector 7 always has a tendency to slide away from the core assembly 2 under the elastic force of the return spring 8. The top pressure head 7b includes a U-shaped base plate 7b1, and the root of the U-shaped base plate 7b1 is fixedly connected to the center of the baffle 7c. The lower side surface of the U-shaped base plate 7b1 is fixedly connected to a U-shaped convex strip 7b2, and the guide surface 7b21 is provided on the U-shaped convex strip 7b2. Two support bars 4d are fixedly connected to the lower surface of the circular partition 3a, and clamping bars 7b3 are fixedly connected to the upper side surfaces of both ends of the U-shaped base plate 7b1, and the two clamping bars 7b3 are embedded between the two support bars 4d, and the side walls of the two clamping bars 7b3 facing each other are respectively against the side walls of the adjacent support bars 4d, and the U-shaped base plate 7b1 is against the two support bars 4d. The U-shaped base plate 7b1 is against the two support bars 4d, so that when the ejector 7 is pushed from the outside to the inside, the top pressure head 7b will not be tilted upward, ensuring the stable cooperation between the top pressure head 7b and the matching part 2c2.

[0048] Embodiment 2
