Description

Technical Field

[0001] The utility model belongs to the technical field of drinking equipment and relates to an automatic wine dispenser. Background Art

[0002] With the progress of the times and the improvement of the quality of life, people's requirements for drinks are getting higher and higher. For example, beer, canned and bottled beer can hardly meet people's drinking needs. More and more people want to drink fresh, hygienic and delicious pure beer. Therefore, the draft beer machine was born. The beer tap, beer spear, dispenser and beer barrel are the main components of the draft beer machine. The dispenser and beer spear lead the beer in the barrel to the beer tap, and the beer tap acts as a switch. When people turn on the beer tap, the beer flows from the beer tap to the glass, so that people can drink fresh beer. Therefore, the tap plays an important role as the last checkpoint to control the beer output.

[0003] In the prior art, most beer taps are manual. For example, Chinese patent document CN105090586B discloses a tap and its connection structure, which includes a valve body with a beer outlet, a valve core slidably arranged in the valve body, and a handle. When in use, people only need to manually turn the handle to operate the valve core to slide relative to the valve body, thereby controlling the beer outlet to open or close, thereby realizing the opening and closing control of the tap. However, as people's requirements for intelligence are getting higher and higher, the existing manual taps can no longer meet the requirements of intelligent control. For this reason, people have developed an electric-controlled faucet based on the existing manual faucet. The electric-controlled faucet is also called an electronic faucet or an automatic wine dispenser. The electric-controlled faucet uses a driving motor to control the opening and closing of the faucet. For example, Chinese patent document CN220581792U discloses an electric-controlled faucet assembly, which includes a faucet and a housing. A driving motor is arranged in the housing. The faucet includes a faucet body, a joint and a manipulation handle. The joint is detachably connected to the faucet body through a locking nut, and the joint is fixedly connected to the housing. The faucet body is indirectly connected to the housing through the joint. A driving arm is arranged in the housing. The driving arm has a cylindrical driving part, which is sleeved outside the manipulation handle. The driving arm can push the manipulation handle to swing through the driving part under the drive of the driving motor. The electric-controlled faucet assembly realizes the automatic opening and closing of the faucet, and has a simple and compact structure.

[0004] However, the valve core of the existing faucet is slidably set in the valve body, and the spring force needs to be overcome to open the valve core. Since the wine will decompose sugar and cause the wine to have a certain viscosity, after the faucet is used for a long time, the surface of the valve core is in sliding contact with the valve body, and the spring is also in contact with the valve core and the valve body. In other words, such valve core and spring are prone to residual wine, and due to the viscosity of the wine, they adhere to the valve body, which requires a greater driving force to open the valve core. The longer the time, the greater the driving force required. After changing to electric drive, the electric driving force provided by the driving motor is fixed. Therefore, in order to ensure that the driving motor has sufficient driving force to open the valve core, the driving motor is often set with a relatively large power, resulting in a relatively high energy consumption of the wine dispenser. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and to propose an automatic wine dispenser. The technical problem to be solved by the utility model is how to reduce the energy consumption of the wine dispenser.

[0006] The purpose of the utility model can be achieved through the following technical solutions: an automatic wine dispenser, comprising an electric drive, a valve body with a wine outlet and an operating member transmission-connected to the electric drive, a valve core is arranged in the valve body, and the characteristic is that the valve core is made of rubber material and comprises an annular connecting part, the inner circumferential surface of the connecting part has a block-shaped sealing part extending toward the center of the connecting part, a clearance gap is formed between the sealing part and the connecting part, the connecting part is fixed in the inner cavity of the valve body, the inner end of the operating member is sheet-shaped and the inner end passes through the connecting part and is inserted into the sealing part.

[0007] Different from the sliding valve core used in the prior art, the utility model has made a fundamental improvement to the valve core of the automatic wine dispenser. Through the specially designed valve core structure, the operating part can rely on the valve core structure to control the swing of the valve core sealing part, so that the sealing part of the valve core does not contact and cooperate with the inner wall of the valve body and can also realize the movement control of the opening and closing of the wine outlet hole, thereby avoiding the valve core from sticking to the valve body after long-term use, thereby achieving the purpose of reducing the energy consumption of the wine dispenser. Specifically, the valve core of the utility model is made of rubber material and includes an annular connecting portion, and a block-shaped sealing portion extending toward the center of the connecting portion is designed on the inner circumferential surface of the connecting portion, a clearance gap is formed between the sealing portion and the connecting portion, and the connecting portion is fixed in the inner cavity of the valve body. With such a design, since the connecting portion is elastic and fixed to the valve body, the sealing portion can be swung in the valve body with the connecting portion as the connecting fulcrum and the swing fulcrum, and the characteristic of the elastic deformation of the connecting portion is utilized, and the clearance gap provides the sealing portion with sufficient swinging space, thereby realizing the swing setting of the valve core relative to the valve body; and in the process of the sealing portion swinging relative to the valve body, due to the separation of the above-mentioned connecting portion and the clearance gap, there is no contact between the sealing portion and the inner circumferential wall of the valve body; at the same time, the inner end of the operating member of the utility model is sheet-shaped and passes through the connecting portion and is inserted into the sealing portion, so that the operating member can be swung with the connecting portion as the connecting fulcrum. The swing fulcrum realizes the swing control of the sealing part to perform the above-mentioned swinging action, so that the operating part can drive the sealing part to swing back and forth under the drive of the electric drive part, and finally the sealing part blocks or opens the wine outlet. In this process, the valve core sealing part of the utility model realizes the movement control of the opening and closing of the wine outlet without contacting and cooperating with the inner circumferential wall of the valve body, thereby completely avoiding the problem of the valve core easily sticking to the valve body after long-term use, thereby reducing the electric driving force required for the operating part to control the opening of the valve core, and reducing energy consumption; and the valve core swing reset of the present application does not require spring-assisted reset, so the valve core cancels the existing spring structure, thus avoiding the problem of the existing spring being prone to adhesion after long-term use, and the elastic deformation of the connecting part can also play a certain auxiliary role in the resetting of the valve core, which is also conducive to further reducing the driving force required for the operating part to control the swing of the valve core, and further reducing the energy consumption of the wine dispenser.

[0008] In the above-mentioned automatic wine dispenser, the valve body is provided with a mounting port communicating with the inner cavity of the valve body, and the connecting portion blocks the mounting port. Through the above design, the connecting portion not only has a connecting function, but also has a sealing function of sealing the mounting port, that is, the connecting portion in the valve core has two uses, so that the mounting port does not need to be provided with a conventional sealing component, so that the operating member controls the swing of the valve core only by overcoming the elastic resistance of the connecting portion, which is conducive to reducing the driving force required for the operating member to control the swing of the valve core, thereby further reducing the energy consumption of the wine dispenser.

[0009] In the above-mentioned automatic wine dispenser, the operating member is a metal member in the form of a long strip, the outer end of the operating member is transmission-connected to the electric drive member, and the inner end of the operating member passes through the installation opening and is embedded and connected with the connecting portion and the blocking portion. Through the above design, the connecting portion not only provides sealing for the installation opening and the operating member, but also provides a fulcrum for the connection of the operating member, thereby realizing the swing connection between the operating member and the valve body; at the same time, by embedding the operating member in the connecting portion and the blocking portion, the inner end of the operating member extending into the valve body is completely wrapped, and there is no sealing gap between the operating member and the connecting portion, that is, the wine will not penetrate between the operating member and the connecting portion, thus avoiding the problem of the operating member sticking and causing the loss of electric drive force; and because the connecting portion is wrapped on the outer peripheral surface of the operating member, the operating member will not generate friction with the valve body during the swinging process, which is conducive to reducing the loss of electric drive force, thereby helping to reduce the energy consumption of the wine dispenser.

[0010] In the above automatic wine dispenser, the distance from the connection between the connecting part and the operating member to the outer end of the operating member is greater than the distance to the inner end of the operating member. Through the above lever design, the electric driving force that drives the operating member to drive the blocking part to open can be smaller, which is beneficial to reducing the energy consumption of the wine dispenser.

[0011] In the above-mentioned automatic wine dispenser, the electric drive member drives the operating member to swing along the axial direction of the wine outlet. Through the above design, the blocking portion of the valve core can swing along the axial direction of the wine outlet, ensuring that the valve core has enough force to press against the valve body and block the wine outlet, thereby controlling the closing of the wine outlet. When the valve core moves away from the wine outlet along the axial direction of the wine outlet, the wine outlet can be controlled to open. In this process, since the valve core adopts the above-mentioned movement mode of swinging along the axial direction of the wine outlet, no continuous movement friction is generated between the valve core and the valve body at the position where the wine outlet is opened, which is conducive to reducing the electric drive force required for the operating member to control the swing of the valve core.

[0012] In the above automatic wine dispenser, the blocking part has a round cake-shaped core, and the axis of the core coincides with the axis of the wine outlet. Through the above design, the blocking part can achieve blocking with a relatively small swing amplitude, which is conducive to reducing energy consumption.

[0013] In the above-mentioned automatic wine dispenser, the valve body includes a first half-valve body and a second half-valve body. The first half-valve body and the second half-valve body are fixedly connected to each other, and a sealing groove is formed when they are closed. 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 through the above-mentioned cooperation with the sealing groove. That is to say, the connecting part not only has the function of swing connection for the blocking part, but also has the sealing function of sealing the valve body. That is to say, the connecting part in this valve core serves multiple purposes, which is beneficial to simplifying the structure of the automatic wine dispenser and reducing the manufacturing cost. On the other hand, through the above design of the split valve body and the annular connecting part, it is convenient for the connection and assembly of the valve body and the valve core.

[0014] In the above-mentioned automatic wine dispenser, a partition part is provided in the valve body. A boss part protrudes from one side of the partition part, and the wine outlet hole is opened in the boss part. The blocking part can swing and abut against the end face of the boss part to block the wine outlet hole. Through the above design of the boss part, the contact area between the blocking part and the valve body can be reduced, which is beneficial to reducing the area where the blocking part may adhere to the valve body where the wine outlet hole is located, thereby being beneficial to reducing the electric drive loss and further being beneficial to reducing the energy consumption of the wine dispenser.

[0015] In the above-mentioned automatic wine dispenser, the end face of the boss part is an inclined plane. Through the above design of the inclined plane, it makes it easier for the blocking part to fit with the boss part through swinging to block the wine outlet hole, which is beneficial to reducing the electric drive force required to drive the blocking part to block the wine outlet hole, thereby being beneficial to reducing the energy consumption of the wine dispenser.

[0016] In the above-mentioned automatic wine dispenser, the electric drive member includes a drive shaft capable of telescopic movement. The outer end of the operating member has a T-shaped bayonet, and the drive shaft has a conical connecting head, and the connecting head is snap-connected to the bayonet. Through the above design of directly connecting the drive shaft and the operating member, there are no other transmission parts between the electric drive member and the operating member, so that the electric drive member can maximize the transmission of the driving force to the operating member, which is beneficial to reducing the transmission loss of the driving force and thus beneficial to reducing the energy consumption of the wine dispenser.

[0017] In the above-mentioned automatic wine dispenser, the automatic wine dispenser further includes a housing and a storage battery arranged in the housing. The electric drive member is located in the housing and is powered by the storage battery. Through the above design of the built-in storage battery, this wine dispenser can be applied to an environment without a socket, which is beneficial to expanding the applicable range of this wine dispenser.

[0018] Compared with the prior art, the automatic wine dispenser has the following advantages: By designing a swinging special valve core, the sealing part of the valve core can achieve the opening and closing control of the wine outlet hole without contacting and cooperating with the inner peripheral wall of the valve body, thus avoiding the adhesion between the valve core and the valve body after long-term use. And the valve core uses the lever principle to achieve the control of swinging, which is very labor-saving. The above comprehensive design results in a relatively small electric driving force required to open the valve core, greatly reducing the energy consumption of the wine dispenser.
