Description

Automatic wine dispenser TECHNICAL FIELD

[0001] The present application belongs to the technical field of drinking equipment, and relates to an automatic wine dispenser. BACKGROUND

[0002] With the progress of the times and the improvement of the quality of life, people's requirements for drinks are also getting higher and higher. For example, canned and bottled beer has been difficult to meet people's drinking needs, and more and more people hope to drink fresh, hygienic, delicious and pure beer. Therefore, a draught beer machine is born. Beer tap, wine spear, distributor and beer barrel are the main components of the draught beer machine equipment. The distributor and the wine spear lead the beer in the beer barrel out to the beer tap. The beer tap plays the role of on-off. When people open the beer tap, the beer flows out of the beer tap into the beer cup, so that people can drink fresh beer. Therefore, the tap plays an important role as the last link of controlling the wine outflow.

[0003] In the prior art, the beer tap is mostly manual, for example, a tap and a connecting structure thereof disclosed in Chinese patent document No. CN105090586B. The tap includes a valve body with a wine outlet hole, a valve core slidingly arranged in the valve body and a handle. When in use, people only need to manually bend the handle to slide the valve core relative to the valve body to control the opening or closing of the wine outlet hole, thereby realizing the on-off control of the tap. However, with the increasing demand for intelligence, the existing manual tap has been unable to meet the requirements of intelligent control. Therefore, on the basis of the existing manual tap, people have developed an electric control tap, also known as an electronic tap or an automatic wine dispenser. The electric control tap uses a driving motor to control the opening and closing of the tap. For example, an electric control tap assembly disclosed in Chinese patent document No. CN220581792U includes a tap and a shell. The shell is provided with a driving motor. The tap includes a tap body, a connector and a control handle. The connector is detachably connected to the tap body through a locking nut. The connector is fixedly connected to the shell. The tap body is indirectly connected to the shell through the connector. The shell is provided with a driving arm. The driving arm has a cylindrical driving portion. The driving portion is sleeved outside the control handle. The driving arm can drive the control handle to swing through the driving portion under the driving of the driving motor. The electric control tap assembly realizes the automatic opening and closing of the tap, and has a simple and compact structure.

[0004] However, the valve core of the existing faucet is arranged in the valve body in sliding mode, and the opening of the valve core needs to overcome the spring force. Since the wine liquid will decompose sugar and cause the wine liquid to have certain viscosity, the surface of the valve core is in sliding contact with the valve body, and the spring is in contact with the valve core and the valve body. That is, the valve core and the spring are easy to retain wine liquid, and after long-term use of the faucet, the wine liquid will be adhered to the valve body due to the viscosity of the wine liquid. This results in the need for greater driving force to open the valve core. The longer the faucet is used, the greater the driving force required. After being replaced by an electric drive, since the electric drive provided by the driving motor is fixed, in order to ensure that the driving motor has sufficient driving force to open the valve core, the driving motor often needs to be set to have a relatively large power, resulting in high energy consumption of the wine dispenser.

[0005] SUMMARY

[0006] The purpose of the present application is to solve the above-mentioned problems existing in the prior art, and to provide an automatic wine dispenser. The technical problem to be solved by the present application is how to reduce the energy consumption of the wine dispenser.

[0007] The purpose of the present application can be achieved by the following technical scheme: an automatic wine dispenser, comprising an electric drive, a valve body with a wine outlet hole, and a control member connected in transmission with the electric drive, the valve body is provided with a valve core, characterized in that the valve core is made of rubber material and comprises a ring-shaped connecting part, the inner circumferential surface of the connecting part is provided with a block-shaped sealing part extending to the center of the connecting part, a clearance is formed between the sealing part and the connecting part, the connecting part is fixed in the inner cavity of the valve body, and the inner end of the control member is in the form of a sheet and is inserted into the sealing part through the connecting part.

[0008] Different from the sliding valve core used in the prior art, the valve core of the automatic wine dispenser is fundamentally improved, the valve core structure is specially designed, the operating member can rely on the valve core structure to realize the swinging of the blocking part of the valve core, the blocking part of the valve core can move to control the opening and closing of the wine outlet hole without contacting the inner circumferential wall of the valve body, thereby avoiding the adhesion between the valve core and the valve body after long-time use, and the purpose of reducing the energy consumption of the wine dispenser is achieved. Specifically, the valve core is made of rubber material and includes a ring-shaped connecting part, a block-shaped blocking part extending to the center of the connecting part is designed on the inner circumferential surface of the connecting part, a clearance is formed between the blocking part and the connecting part, and the connecting part is fixed in the inner cavity of the valve body. Due to the elasticity of the connecting part and the fixation of the connecting part to the valve body, the blocking part can swing in the valve body by taking the connecting part as the connecting and swinging fulcrum, and the clearance provides sufficient swinging space for the blocking part, so that the valve core is swingably arranged relative to the valve body. During the swinging of the blocking part relative to the valve body, the connecting part and the clearance are separated, so that the blocking part does not contact the inner circumferential wall of the valve body. Meanwhile, the inner end of the operating member is in a sheet shape and penetrates through the connecting part and is inserted into the blocking part, so that the operating member can swing by taking the connecting part as the swinging fulcrum and control the blocking part to perform the above-mentioned swinging action, thereby enabling the operating member to drive the blocking part to reciprocally swing under the drive of the electric drive member, and finally enabling the blocking part to block or open the wine outlet hole. During the process, the valve core blocking part of the present application realizes the movement control of the opening and closing of the wine outlet hole without contacting the inner circumferential wall of the valve body, thereby completely avoiding the problem that the valve core is easily adhered to the valve body after long-time use, and further reducing the electric drive force required for the operating member to control the opening of the valve core and reducing the energy consumption. Furthermore, the valve core swing reset does not require spring auxiliary reset, so that the valve core cancels the existing spring structure, thereby avoiding the problem that the existing spring is easily adhered after long-time use, and the elastic deformation of the connecting part can also play a certain auxiliary role in the reset of the valve core, so that it is also conducive to further reducing the driving force required for the operating member to control the swinging of the valve core and further reducing the energy consumption of the wine dispenser.

[0009] In the automatic wine dispenser, the valve body is provided with a mounting port communicating with the inner cavity of the valve body, and the connecting part blocks the mounting port. Through the above design, the connecting part not only has the connection function, but also has the sealing function of sealing the mounting port, that is, the connecting part in the valve core has two functions, so that the mounting port does not need to be provided with a conventional sealing part, thereby enabling the operating member to control the swinging of the valve core only by overcoming the elastic resistance of the connecting part, which is conducive to reducing the driving force required for the operating member to control the swinging of the valve core, thereby further reducing the energy consumption of the wine dispenser.

[0010] In the automatic wine dispenser, the operating member is a long strip-shaped metal piece, the outer end of the operating member is connected with the electric drive member, and the inner end of the operating member penetrates through the installation opening and is embeddedly connected with the connecting part and the blocking part. Through the above design, the connecting part provides sealing for the installation opening and the operating member, and also provides a fulcrum for the connection of the operating member and the valve body, so as to realize the swing connection of the operating member and the valve body. Meanwhile, the inner end of the operating member that penetrates into the valve body is completely wrapped up by embedding the operating member in the connecting part and the blocking part, and there is no sealing gap between the operating member and the connecting part, that is, the wine cannot penetrate between the operating member and the connecting part, so that the problem of the electric drive force loss caused by the sticking of the operating member is avoided. Moreover, since the connecting part is wrapped on the outer circumferential surface of the operating member, the operating member will not rub against the valve body during the swing, which is beneficial to reduce the loss of electric drive force and thus reduce the energy consumption of the wine dispenser.

[0011] In the automatic wine dispenser, the distance from the connecting part to the outer end of the operating member is greater than the distance from the connecting part to the inner end of the operating member. Through the above lever design, the electric drive force required to drive the operating member to open the blocking part can be smaller, thereby reducing the energy consumption of the wine dispenser.

[0012] In the automatic wine dispenser, the electric drive member drives the operating member to swing along the axial direction of the wine outlet hole. Through the above design, the blocking part of the valve core can swing along the axial direction of the wine outlet hole, so that the blocking part of the valve core can tightly close the wine outlet hole by applying a sufficient force on the valve body at the opening position of the wine outlet hole. In this way, the opening and closing of the wine outlet hole can be controlled. During the process, since the blocking part of the valve core adopts the above-mentioned moving mode of swinging along the axial direction of the wine outlet hole, the continuous moving friction between the blocking part of the valve core and the valve body at the opening position of the wine outlet hole is avoided, which is beneficial to reduce the electric drive force required for the operating member to control the swing of the valve core.

[0013] In the automatic wine dispenser, the blocking part has a core body in the shape of a round cake, and the axis of the core body coincides with the axis of the wine outlet hole. Through the above design, the blocking part can realize blocking with a smaller swing amplitude, thereby reducing the energy consumption.

[0014] In the automatic wine dispenser, the valve body comprises a first half valve body and a second half valve body, the first half valve body and the second half valve body are fixed to each other and are folded to form a sealing groove, and the connecting part is embedded in the sealing groove to form a seal. On the one hand, the connecting part is fixed to the inner cavity of the valve body by cooperating with the sealing groove, that is, the connecting part not only has the function of connecting the sealing part, but also has the sealing function of the valve body, that is, the connecting part is used in multiple ways, which is beneficial to simplify the structure of the automatic wine dispenser and reduce the manufacturing cost. On the other hand, the design of the ring-shaped connecting part cooperates with the split valve body, which is convenient for the connection and assembly of the valve body and the valve core.

[0015] In the automatic wine dispenser, the valve body has an annular side wall formed by reducing the inner hole diameter, the annular side wall is a partition, one side of the partition protrudes a boss part, the wine outlet hole is arranged in the boss part, and the sealing part can be abutted on the end face of the boss part by swinging to seal the wine outlet hole. Through the design of the boss part, the contact area of the sealing part and the valve body can be reduced, which is beneficial to reduce the area of the sealing part and the wine outlet hole that may be adhered in the valve body, thereby reducing the power consumption of the wine dispenser.

[0016] In the automatic wine dispenser, the end face of the boss part is an inclined surface. Through the design of the inclined surface, the sealing part is more easily abutted on the boss part to seal the wine outlet hole by swinging, which is beneficial to reduce the electric drive force required to drive the sealing part to seal the wine outlet hole, thereby reducing the energy consumption of the wine dispenser.

[0017] In the automatic wine dispenser, the electric drive part comprises a driving shaft capable of telescopic movement, the outer end of the operating part has a T-shaped bayonet, the driving shaft has a tapered connecting head, and the connecting head is connected with the bayonet. Through the direct connection design of the driving shaft and the operating part, there is no other transmission part between the electric drive part and the operating part, so that the electric drive part can maximize the transmission of driving force to the operating part, thereby reducing the transmission loss of driving force and reducing the energy consumption of the wine dispenser.

[0018] In the automatic wine dispenser, the automatic wine dispenser further comprises a housing and a storage battery arranged in the housing, and the electric drive part is located in the housing and is powered by the storage battery. Through the design of the built-in storage battery, the wine dispenser can be applied to a socket-free environment, which is beneficial to improve the application range of the wine dispenser.

[0019] Compared with the prior art, the automatic wine dispenser has the following advantages: the automatic wine dispenser is designed with a swing type special valve core, so that the blocking part of the valve core can also realize the movement control of the opening and closing of the wine outlet hole without contacting and cooperating with the inner wall of the valve body, thereby avoiding the adhesion between the valve core and the valve body after long time use, and the valve core utilizes the lever principle to realize the control swing, which is very labor-saving, and the above comprehensive design makes the electric drive force required for opening the valve core smaller, and greatly reduces the energy consumption of the wine dispenser.

[0028] Specifically, as shown in FIG. 1 and FIG. 2, the automatic wine dispenser comprises a housing 6, a battery 7, an electric drive 1 powered by the battery 7, and a valve body 2 with a wine outlet hole 21 arranged in the housing 6. A control member 3 is swingably arranged on the valve body 2 and is in transmission connection with the electric drive 1. A valve core 4 for controlling the opening and closing of the wine outlet hole 21 is arranged in the valve body 2, and the control member 3 is used to control the movement of the valve core 4. The valve core 4 is made of rubber material and comprises a ring-shaped connecting portion 41. The inner circumferential surface of the connecting portion 41 has a block-shaped plugging portion 42 extending to the center of the connecting portion 41. A clearance 5 is formed between the plugging portion 42 and the connecting portion 41 for the swinging of the plugging portion 42. The connecting portion 41 is fixed in the inner cavity of the valve body 2, and the axis of the connecting portion 41 is parallel to or coincides with the axis of the wine outlet hole 21. The plugging portion 42 is swingably arranged in the valve body 2 through the connecting portion 41 and can swing along the axis of the wine outlet hole 21. The inner end of the control member 3 penetrates through the connecting portion 41 and is fixedly connected to the plugging portion 42. The control member 3 can drive the plugging portion 42 to swing reciprocally in the inner cavity of the valve body 2 along the axis of the wine outlet hole 21 under the drive of the electric drive 1, and can make the plugging portion 42 plug or open the wine outlet hole 21. As shown in FIG. 3, the valve body 2 has an annular side wall formed by the inner hole with a smaller diameter. The annular side wall is a partition portion 23. One side of the partition portion 23 protrudes a boss portion 231, and the wine outlet hole 21 is arranged in the boss portion 231. The end surface of the boss portion 231 is an inclined surface 2311. The plugging portion 42 can swing and abut against the inclined surface 2311 of the boss portion 231 to plug the wine outlet hole 21.

[0029] More specifically, as shown in FIG. 3, FIG. 4 and FIG. 5, the valve body 2 further has a mounting port 22 in communication with the inner cavity of the valve body 2. The connecting portion 41 is fixed at the mounting port 22 and blocks the mounting port 22. The inner end of the control member 3 penetrates through the mounting port 22 and is embedded in the connecting portion 41 and the plugging portion 42. The control member 3 is swingably connected to the valve body 2 with the connecting portion 41 as the fulcrum. The distance from the connecting portion 41 to the outer end of the control member 3 is greater than the distance from the connecting portion 41 to the inner end of the control member 3. In this embodiment, the valve body 2 comprises a first half valve body 2a and a second half valve body 2b. The first half valve body 2a and the second half valve body 2b are fixedly connected to each other. The first half valve body 2a and the second half valve body 2b respectively have annular notches at the ports. The two annular notches are folded to form a sealing groove 2c, and the connecting portion 41 is embedded in the sealing groove 2c. The plugging portion 42 is in the shape of a water droplet and has a round cake-shaped core 421. The axis of the core 421 coincides with the axis of the wine outlet hole 21. The outer circumferential surface of the plugging portion 42 and the inner circumferential surface of the connecting portion 41 form a horseshoe-shaped clearance 5.

[0030] As shown in Fig. 2 and Fig. 3, the wine outlet 21 is arranged in the half valve body 2a, and a bend pipe 8 is connected to the wine outlet 21 at an end of the half valve body 2a opposite to the half valve body 2b, one end of the bend pipe 8 is connected to a butt joint 9 fixed on the shell 6, an outer end of the butt joint 9 is connected to a wine outlet pipe 10, and the bend pipe 8 is communicated with the wine outlet pipe 10 through the butt joint 9. A wine passing hole 24 opposite to the wine outlet 21 is arranged through the half valve body 2b, and the blocking part 42 is located between the wine outlet 21 and the wine passing hole 24. The hole diameter of the hole opening of the wine passing hole 24 towards the blocking part 42 is larger than the outer diameter of the core 421 of the blocking part 42, so as to avoid the contact between the core 421 and the hole of the wine passing hole 24 when the core 421 opens the wine outlet 21. As shown in Fig. 1, a connecting pipe 12 is connected to the wine passing hole 24 at an end of the half valve body 2b opposite to the half valve body 2a, and the connecting pipe 12 is used to connect with a wine barrel or other wine storage device.
