Description

Technical Field

[0001] This utility model belongs to the field of beverage equipment technology and relates to an electric drive structure for a tap. Background Technology

[0002] Drinking beer from kegs typically requires a tap, the specific structure of which is disclosed in Chinese Patent (Authorization Announcement No.: CN105090586B) as a tap and its connection structure, including a valve body and a connecting pipe. The connecting pipe is threaded, and the valve body has a connecting end connected to the connecting pipe. The valve body and the connecting pipe are fixed together by a connecting cap. The inner surface of the connecting end is provided with an internal toothed ring, and the connecting pipe is provided with an external toothed ring that can mesh with the internal toothed ring. A sealing ring is provided between the connecting end of the valve body and the connecting pipe.

[0003] Combined with the appendix of this comparison document Figure 3 As can be seen, the use of this tap involves the user pushing or turning the handle, which causes the valve core inside the valve head to slide, thereby opening or closing the wine passage. Although this method allows for the extraction of wine, in practice, the user needs to repeatedly turn or push the handle, making the wine extraction process very inconvenient. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing an electric drive structure for a faucet. The technical problem to be solved by this utility model is: how to improve the convenience of wine sipping.

[0005] The objective of this utility model can be achieved through the following technical solution: an electric drive structure for a faucet, the faucet including a body, a valve core slidably connected to the body, and a valve stem rotatably connected to the body and capable of driving the valve core to slide. The electric drive structure includes a housing, a servo motor fixed in the housing with its drive end facing downward, and a push rod slidably connected in the housing along the axial direction of the valve core. The push rod is located between the drive end of the servo motor and the valve stem. A gear is fixed to the drive end of the servo motor. One end of the push rod is connected to the valve stem and can push the valve stem to swing. The other end of the push rod is provided with a rack along the axial direction of the valve core. The servo motor is connected to the gear and the rack through a transmission connection, enabling the push rod to slide and drive the valve stem to swing.

[0006] The working principle of this application is as follows: A servo motor is used as the driving device. The gear fixed to its driving end rotates with the driving end of the servo motor. The gear and push rod are connected to a rack formed on the push rod to achieve transmission. In this process, the transmission between the gear and the rack causes the push rod to move forward or backward along the axial direction of the valve core. The push rod is connected to the valve stem used to drive the valve core to slide. When the push rod slides forward, it can drive the valve stem to swing and drive the valve core to slide backward along the axial direction, so that the valve core closes the wine passage in the body. Conversely, when the push rod slides backward, it can drive the valve stem to swing in the opposite direction and drive the valve core to slide forward along the axial direction, so that the valve core opens the wine passage in the body. In the whole process, the opening and closing of the wine passage can be automatically controlled by the cooperation of the servo motor, push rod, valve stem and valve core. Compared with the existing technology, there is no need to manually control the opening and closing of the tap to draw wine, making the operation more convenient.

[0007] In the aforementioned electric drive structure of the faucet, a spherical groove is formed on the bottom surface of one end of the push rod. The outer end of the valve stem extends out of the body and is inserted into the spherical groove, with its outer circumferential surface fitting against the inner circumferential wall of the groove. A strip-shaped opening is formed along the axial direction on the top surface of the other end of the push rod. A rack is formed on the inner wall of one side of the strip-shaped opening, and the gear extends into the strip-shaped opening and meshes with the rack. One end of the push rod is inserted into the outer end of the valve stem through the spherical groove, and the outer circumference of the outer end fits against the inner circumferential wall of the spherical groove, thereby realizing the connection and transmission between the push rod and the valve stem. Based on this, by forming a strip-shaped opening along the axial direction at the top of the push rod and shaping the rack on the inner wall of one side of the strip-shaped opening, the rational arrangement within a limited space is ensured, ensuring that the gear and rack can cooperate to drive the push rod forward or backward along the axial direction.

[0008] In the aforementioned electric drive structure of the faucet, the strip-shaped opening penetrates the bottom surface of the push rod. The inner walls on both sides of the strip-shaped opening have inwardly protruding and opposing abutment portions along their length. The drive end of the servo motor is fixed with a limiting plate by screws. The limiting plate and the side of the gear are positioned opposite each other. The gear abuts against the upper sides of the two abutment portions, and the limiting plate abuts against the lower sides of the two abutment portions. This arrangement positions the limiting plate at the drive end of the servo motor, ensuring its surface faces one side of the gear. After installation, the gear abuts against the upper sides of the two abutment portions, and the limiting plate abuts against the lower sides of the two abutment portions, thus limiting the push rod and preventing it from moving up and down during axial sliding.

[0009] In the aforementioned electric drive structure of the helm, a bracket is provided at the bottom of the servo motor inside the housing. The servo motor is fixed to the bracket with screws, and the bracket is fixed to the inner wall of the housing with screws. A through-shaft hole is provided on the bracket above the strip-shaped opening, and the drive end of the servo motor passes through the through-shaft hole. The top of the main body has a U-shaped connecting part. The lower end of the bracket and the outer walls of both sides of the connecting part are attached and locked together with high-head screws. With this configuration, the servo motor and the push rod connected to the drive end of the servo motor are integrated into the housing through the bracket, thus realizing an integrated modular structure for the electric drive. During assembly and use, transmission is achieved through the connection between the push rod and the valve stem. The high-head screws are used to lock the connecting part on the bracket and the main body, thereby positioning the housing, the bracket inside the housing, and the servo motor on the bracket onto the main body. The push rod passes through the through-shaft hole on the bracket, realizing the transmission between the push rod and the valve stem.

[0010] In the aforementioned electric drive structure of the faucet, limiting grooves are formed on both sides of the housing, and the lower side of each limiting groove extends through the lower edge of the housing. Each limiting groove is equipped with a head screw, and the shank of each head screw sequentially passes through the limiting groove, the bracket, and the connecting part for screwing. The nut of each head screw is correspondingly tightened against the bottom wall of each limiting groove. This arrangement ensures that the housing can fully cover the top area of ​​the faucet, preventing internal components from being exposed while further improving the connection stability between the housing and the body.

[0011] Compared with existing technologies, the electric drive structure of this faucet has the following advantages: it uses a servo motor as the drive source and a push rod that is slidably connected to the housing along the valve core axis as the drive medium. The push rod has a spherical groove at one end that is inserted into the outer end of the valve stem. The gear fixed at the drive end of the servo motor cooperates with the rack arranged along the length of the other end of the push rod to achieve transmission, so that the push rod drives the valve stem to swing to drive the valve core to slide open or close the wine circuit, making the operation more convenient.

The electric drive structure includes a housing 2, within which a servo motor 21, a bracket 23, and a long, plate-shaped push rod 22 are provided. The push rod 22 is slidably connected to the valve core 11 along the axial direction within the housing 2, and a bottom opening at one end of the push rod 22 is provided. The outer end of the valve stem 12 is inserted into the spherical groove 222, and the outer peripheral wall of the outer end of the valve stem 12 is in contact with the inner peripheral wall of the spherical groove 222. The top of the other end of the push rod 22 has a strip-shaped opening 223 along the axial direction, and the strip-shaped opening 223 extends to the bottom of the push rod 22. A rack 221 is formed on the inner wall of the push rod 22 along the axial direction of the valve core 11 on one side of the strip-shaped opening 223. The drive end of the servo motor 21 is set downwards, and a gear 211 is fixed on the drive end of the servo motor 21, and the gear 211 and the rack 221 mesh with each other.

[0022] like Figure 1-7As shown, bracket 23 is located at the bottom of servo 21 and is fixed to servo 21 by screws. Bracket 23 is also fixed to the inner wall of housing 2 by screws, thereby ensuring the positioning of bracket 23 itself and servo 21 on bracket 23 in housing 2. A through-shaft hole 231 is provided on bracket 23 above the slot 223. The drive end of servo 21 passes through the through-shaft hole 231, thereby avoiding interference between gear 211 and bracket 23. Limit plate 212 is fixed to the drive end of servo 21 by screws. The plate surface of limit plate 212 and one side of gear 211 are opposite to each other. There are two oppositely arranged abutment parts 2231 in slot 223. The two abutment parts 2231 are arranged along the length of slot 223. The lower side of gear 211 abuts against the upper side of the two abutment parts 2231, and the limit plate 212 abuts against the lower side of the two abutment parts 2231.

[0023] like Figure 7 As shown, a U-shaped connecting portion 13 is located at the top of the main body 1. Connecting holes are provided on the outer walls of both sides of the connecting portion 13. The bottom of the bracket 23 abuts against the outer walls of both sides of the connecting portion 13. A mating hole is provided at the bottom of the bracket 23 corresponding to the connecting hole. The bracket 23 is screwed into the mating hole and the connecting hole in sequence by high-head screws 3, thereby positioning the bracket 23, along with the servo motor 21 and the housing 2, on the main body 1. In addition, as Figure 3 As shown, limit grooves 24 are provided on both sides of the lower end of the housing 2. The lower side of each limit groove 24 extends through the lower edge of the housing 2. A strip-shaped notch is provided on the bottom wall of each limit groove 24. The head screw 3 is screwed through the notch, the mating hole and the connecting hole, and is tightened against the bottom wall of the limit groove 24 by the nut. Thus, the housing 2 is further clamped by the cooperation of the head screw 3 and the connecting part 13. There can be multiple limit grooves 24 provided on both sides of the housing 2. Each limit groove 24 is provided with a head screw 3 and the connecting part 13 screwed together.

[0024] Operating principle: The user starts the servo motor 21, causing the drive end of the servo motor 21 to drive the gear 211 to rotate forward. The push rod 22 is driven forward and slides through the gear teeth of the rack 221 and the gear 211, thereby causing the inner end of the valve stem 12 to swing backward, which in turn causes the valve core 11 to slide backward and open the wine passage. At this time, the user can draw wine through the body 1. After the wine is drawn, the drive end of the servo motor 21 drives the gear 211 to rotate backward. The push rod 22 is driven backward and slides through the gear teeth of the rack 221 and the gear 211, thereby causing the inner end of the valve stem 12 to swing forward, which in turn causes the valve core 11 to slide backward and close the wine passage.
