Description

Technical Field

[0001] This utility model belongs to the field of drinking equipment technology and relates to a manual / automatic electronic faucet. Background Technology

[0002] With the progress of the times and the improvement of living standards, people's requirements for beverages are also getting higher and higher. For example, canned and bottled beer can no longer satisfy people's drinking needs. More and more people want to drink fresh, hygienic, and delicious pure beer. Therefore, draft beer machines were born. The beer tap, beer spear, dispenser, and keg are the main components of a draft beer machine. The dispenser and beer spear draw the beer from the keg to the beer tap, which acts as an on / off switch. When people open the beer tap, the beer flows from the tap into the glass, allowing them to drink fresh beer. Therefore, the tap, as the last checkpoint controlling the beer dispensing, plays an important role.

[0003] In existing technologies, 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 dispensing hole, a valve core slidably disposed within the valve body, and a handle. In use, users simply need to manually move the handle to slide the valve core relative to the valve body, thereby controlling the opening or closing of the dispensing hole, thus achieving tap opening and closing control. The output can also be freely selected as needed. However, with increasing demands for intelligent systems, existing manual taps can no longer meet the requirements of intelligent control. To address this, an electrically controlled faucet, also known as an electronic faucet, has been developed based on existing manual faucets. This faucet uses a drive motor to control its opening and closing. For example, Chinese patent document CN220581792U discloses an electrically controlled faucet assembly comprising a faucet and a housing. The housing houses the drive motor. The faucet includes a faucet body, a connector, and a control handle. The connector is detachably connected to the faucet body via a locking nut and is fixedly connected to the housing. The faucet body is indirectly connected to the housing via the connector. A drive arm is located within the housing, and the drive arm has a cylindrical drive section that is fitted over the control handle. Driven by the drive motor, the drive arm can push the control handle to swing through the drive section. This electrically controlled faucet assembly achieves automatic opening and closing of the faucet and has a simple and compact structure.

[0004] However, the aforementioned electronic faucets have the following drawbacks in actual use: Firstly, to ensure the compactness of the faucet structure, the batteries used for power supply are often small in capacity, resulting in relatively short battery life. They become unusable when the battery is low, requiring plugging in or full charging before operation, thus limiting their applicability. Secondly, to avoid the risk of accidental activation or forgetting to turn off, the automatic flow output settings of these electronic faucets are all designed to be quantitative. This means that users can only drink according to the manufacturer's pre-set output, leading to significant limitations and preventing users from freely selecting the output flow as needed, further hindering their applicability. Even without considering the risk of constant operation and eliminating the quantitative design, the user's need for quantitative output cannot be met. Therefore, to enable electronic faucets to simultaneously meet the requirements of free flow output and quantitative output, the conventional technical approach is to design a control program to switch between these two modes, thereby improving applicability and maintaining the original faucet structure's compactness. However, the drawback of the faucet becoming unusable when the power is low, resulting in poor applicability, still exists. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a manual / automatic electronic faucet. The technical problem to be solved by this utility model is how to improve the applicability of the electronic faucet while ensuring its compact structure.

[0006] The objective of this utility model can be achieved through the following technical solution: A manual / automatic electronic faucet includes a body, a valve core disposed within the body, and a valve stem vertically disposed on the body and whose movement of the valve core is controlled by swinging its lower end. The faucet is characterized by further including a switching rod arranged horizontally on the same body, a hand-drive rod for manually driving the valve stem to swing and coaxially arranged with the switching rod, and an electric drive rod for electrically driving the valve stem to swing and arranged vertically. These three rods are arranged around the upper end of the valve stem and form a cross-shaped arrangement with the valve stem. The hand-drive rod and the electric drive rod respectively rotate with the body in the circumferential direction of the switching rod. The outer end of the lever extends out of the body. The inner end of the switching lever has a clutch head that protrudes radially from the outer circumference of the inner end and has a non-circular cross-section. The clutch head is inserted into the upper end of the valve stem and circumferentially positioned, and the two can slide relative to each other. The electric drive lever has a first engagement hole that can be inserted into and circumferentially positioned with the clutch head. The hand drive lever has a second engagement hole that can be inserted into and circumferentially positioned with the clutch head. The first engagement hole and the second engagement hole are located on both sides of the valve stem. By manipulating the outer end of the switching lever, the clutch head can be selectively inserted into and circumferentially positioned with one of the first engagement hole and the second engagement hole.

[0007] This utility model integrates manual mechanical control into an electronic faucet through a clever clutch structure design, allowing the faucet to switch between manual and electric operation modes. This ensures normal operation even when the power is off. In manual mode, the output flow rate can be arbitrarily selected, while in electric mode, it can meet quantitative output requirements. This completely solves the shortcomings of existing electronic faucets, comprehensively improving their applicability. Furthermore, the overall structural design is ingenious and reasonable, ensuring the compactness of the faucet structure. Specifically, this application improves upon existing faucet bodies and valves... Based on the structure of the valve stem and valve core, a switching lever, a manual drive lever, and an electric drive lever are integrated into the same body of the faucet. The switching lever is used to switch between manual and electric drive mechanisms, the manual drive lever is used to manually drive the valve stem to swing, and the electric drive lever is used to electrically drive the valve stem to swing. The switching lever is arranged horizontally, the manual drive lever and the switching lever are arranged coaxially, and the electric drive lever is arranged vertically. All three are arranged around the upper end of the valve stem and form a cross-shaped layout with the valve stem. This special arrangement of the four levers makes full use of the radial space around the faucet body, and the combination of the four to form a cross-shaped layout ensures the compactness of the overall structure.

[0008] Simultaneously, the hand-operated lever and the main body rotate in a circumferential engagement with the switching lever. The outer end of the switching lever extends out of the main body, and the inner end of the switching lever has a clutch head that bulges radially from the outer circumferential surface of the inner end and has a non-circular cross-section. The clutch head is inserted into and circumferentially positioned with the upper end of the valve stem, and the two can slide relative to each other. The electric drive lever has a first engagement hole that can be inserted into and circumferentially positioned with the clutch head, and the hand-operated lever has a second engagement hole that can be inserted into and circumferentially positioned with the clutch head. The first engagement hole and the second engagement hole are located on both sides of the valve stem, respectively. With this design, people only need to move the outer end of the switching lever to allow the clutch head to be inserted into and circumferentially positioned with one of the first engagement holes or the second engagement hole. When the clutch head is switched to engage with the first engagement hole, the clutch head is disengaged from the second engagement hole. At this time, the switching lever and the manual drive lever are not linked; instead, they are linked to the electric drive lever. Since the electric drive lever and the main body rotate circumferentially around the switching lever, simply rotating the electric drive lever relative to the main body will synchronously rotate the switching lever. The switching lever then rotates the upper end of the valve stem, ultimately driving the lower end of the valve stem to swing, thus opening the valve core, i.e., the faucet is in electric drive mode. When the clutch head is switched to engage with the second engagement hole, the clutch head is disengaged from the first engagement hole. At this time, the switching lever and the electric drive lever are not linked; instead, they are linked to the manual drive lever. Since the manual drive lever and the main body rotate circumferentially around the switching lever, the electric drive lever rotates relative to the main body, which in turn drives the switching lever to rotate. This, in turn, drives the upper end of the valve stem to rotate, ultimately driving the lower end of the valve stem to swing, thus opening the valve core, i.e., the faucet is in electric drive mode. The circumferential rotation of the switching lever is coordinated with the manual drive lever. Manually driving the hand-drive lever relative to the main body will synchronously rotate the switching lever, which in turn rotates the upper end of the valve stem, ultimately causing the lower end of the valve stem to swing, thus opening the valve core and putting the faucet in manual mode. Therefore, through the coordinated design of the switching lever, hand-drive lever, electric drive lever, and valve stem, this faucet can switch between manual and electric control modes. In the event of a power outage, it can switch to manual mode, completely solving the drawback of existing electronic faucets being unusable when power is unavailable. Furthermore, this faucet can meet any flow output requirement, thus comprehensively improving its applicability.

[0009] In the aforementioned automatic / manual faucet, the clutch head has a square cross-section, and the second engagement hole is a strip-shaped, waist-shaped hole. The width of the second engagement hole is the same as the width of the clutch head, and the height of the second engagement hole is greater than the height of the clutch head. Through this design of the clutch head and the second engagement hole, since the clutch head and the second engagement hole are only limited by two surfaces, the clutch head is less likely to get stuck when inserted into the second engagement hole, resulting in smoother engagement. This facilitates the disengagement of both components, ensuring the smooth switching between manual and automatic modes of the electronic faucet, thereby effectively improving the applicability of the electronic faucet.

[0010] In the aforementioned automatic / manual faucet, one side of the main body has a mounting post that protrudes radially relative to the main body. The mounting post has a mounting hole, and a mounting cap is fitted and fixedly connected to the mounting post. The outer end of the switching lever extends from the mounting cap through the mounting hole and slides into the mounting cap. The middle section of the switching lever has a shoulder, and a spring is fitted onto the switching lever. One end of the spring abuts against the inner side of the mounting cap, and the other end abuts against the shoulder. This design, on the one hand, requires overcoming the spring's action when moving the switching lever, and the spring also provides a restoring force for the movement of the switching lever, thus improving the feel and safety of the switching lever's clutch operation. On the other hand, the design of the mounting post, which provides mounting space for the switching lever, makes reasonable use of the radial space of the faucet body, and the design of the spring fitted onto the switching lever helps ensure the compactness of the faucet structure.

[0011] In the aforementioned automatic / manual faucet, a switching wrench is hinged to the outer end of the switching lever. Under the action of a spring, the switching wrench is positioned against the outer side of the mounting cap. Rotating the switching wrench allows the switching lever to slide. The bottom of the switching wrench has a first limiting surface, and the side of the switching wrench has a second limiting surface perpendicular to the first limiting surface. The outer side of the mounting cap has a vertically arranged abutment surface. When the first limiting surface abuts against the abutment surface, the clutch head engages with the first engagement hole for circumferential positioning. When the second limiting surface abuts against the abutment surface, the clutch head engages with the second engagement hole for circumferential positioning. Through this switching wrench design, the switching lever can be moved simply by rotating the wrench, making the manual / automatic switching operation of the faucet simple and convenient. This ensures that the faucet can meet the operational needs of both manual and electric modes, thereby improving the faucet's applicability.

[0012] In the aforementioned automatic / manual electronic faucet, the upper side of the main body is provided with a ball socket, and the lower end of the electric drive rod has a hemispherical connecting part one, with a connecting hole one located on the connecting part one. The end of the manual drive rod opposite to the switching rod is the inner end, and this end has a hemispherical connecting part two, with a connecting hole two located on the connecting part two. The connecting parts one and two close together and respectively engage with the inner wall of the ball socket in a circumferential rotational fit with the switching rod. The upper end of the valve stem is located between the connecting parts one and two. Through the above design of the shape of the electric drive rod and the manual drive rod, as well as the positional arrangement of the two with the valve stem, the connection and fit of the three are concentrated at the ball socket. While ensuring the rotational function of each of the three, the structure is very compact when the three are combined, thereby improving the applicability of the electronic faucet while ensuring its compact structure.

[0013] In the aforementioned automatic / manual electronic faucet, the upper end of the valve stem has a disc-shaped rotating part. When the first and second connecting parts are joined, a rotating cavity adapted to the rotating part is formed inside. The outer circumferential surface of the rotating part fits against the cavity wall to form a rotational fit. This design allows the electric and manual actuators to serve dual purposes. While ensuring their basic functions, it also provides a fit for the rotation of the upper end of the valve stem, enabling stable rotation. Furthermore, this fit makes the structure of all three components more compact, thus improving the applicability of the electronic faucet while maintaining a compact structure.

[0014] In the aforementioned automatic / manual electronic faucet, the main body is equipped with an electric drive device. The upper end of the electric drive rod is located outside the faucet body and is driven by the electric drive device. The electric drive device includes a housing, a motor fixed inside the housing, and a push rod slidably connected to the housing along the axial direction of the main body. The push rod is equipped with a rack, and a gear is fixedly connected to the motor shaft of the motor. The gear and the rack are meshed together. One end of the push rod is sleeved on the upper end of the electric drive rod, and the two are linked together. Through the above electric drive device, the electric drive rod can automatically swing, thereby realizing the electric drive of the valve stem swinging.

[0015] In the aforementioned automatic / manual faucet, the push rod has a strip-shaped hole. A rack is located on one side wall of the strip-shaped hole. Both side walls of the strip-shaped hole have inwardly protruding, strip-shaped limiting strips. The rack is located above the limiting strips and parallel to them. The lower part of the rack has a cylindrical sliding part, which is located between and slidably engages with the two limiting strips. A washer is fixed to the lower end face of the sliding part, located below the limiting strips and able to slide along their lower surfaces. This design of the limiting strips and sliding part guides the push rod's movement, making it more stable. The washer and its engagement with the limiting strips prevent the gear from loosening, and the washer's ability to slide along the lower surface of the limiting strips further improves the stability of the push rod's movement. This improved stability allows for better electric control of the electric drive lever's oscillation, making the faucet's electric drive mode reliable.

[0016] In the aforementioned automatic / manual electronic faucet, the upper end of the electric drive rod has a spherical head, and one end of the push rod has a spherical cavity that matches the shape of the spherical head. The spherical head is located inside the spherical cavity, and the two form a rotational engagement. Through the design of the spherical head and the spherical cavity, the linkage between the push rod and the electric drive rod is achieved. This structure makes it very convenient to assemble and disassemble, and the structure is also relatively compact.

[0017] In the aforementioned automatic / manual faucet, the upper side of the main body has a U-shaped connecting portion. The housing covers the connecting portion, and mounting notches are provided on both sides of the bottom edge of the housing. Screws are inserted into the mounting notches, and the housing is fastened to the connecting portion by the screws. With this design, the housing can be disassembled simply by removing the screws, and all other related structures of the electric drive device are integrated into the housing. In other words, removing the housing is equivalent to removing the entire electric drive device, making the cleaning and disassembly of the faucet body very convenient.

[0018] Compared with existing technologies, this automatic / manual electronic faucet has the following advantages:

[0019] 1. This electronic faucet has both manual and electric control modes, which allows it to be used normally even when the power is off. In addition, the manual mode can meet the user's needs for arbitrary flow output, while the electric mode can meet the user's needs for quantitative output, making it very versatile.

[0020] 2. The overall structure of this electronic faucet is very ingeniously designed and arranged, making the overall structure of the electronic faucet very compact. Attached Figure Description

[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, this automatic / manual electronic faucet includes a body 1, a valve core 2 disposed within the body 1, and a valve stem 3 vertically mounted on the body 1 and whose movement of the valve core 2 is controlled by swinging its lower end. For example... Figure 2 and Figure 3 As shown, this automatic / manual electronic faucet also includes a switching lever 4 arranged horizontally on the same body 1, a hand drive lever 5 for manually driving the valve stem 3 to swing and coaxial with the switching lever 4, and an electric drive lever 6 for electrically driving the valve stem 3 to swing and arranged vertically, as shown. Figure 5 As shown, the aforementioned switching lever 4, electric drive lever 6, and electric drive lever 7 are arranged around the upper end of the valve stem 3 in a cross configuration. The hand drive lever 5 and electric drive lever 6 are respectively rotatably engaged with the body 1 in the circumferential direction of the switching lever 4. The outer end of the hand drive lever 5 extends out of the body 1, and a handle 15 perpendicular to the hand drive lever 5 is fixedly connected to this end. The outer end of the switching lever 4 extends out of the body 1, and the inner end of the switching lever 4 has a clutch head 41 that bulges radially outward from the outer circumferential surface of the inner end and has a non-circular cross-section. Figure 6As shown, in this embodiment, the clutch head 41 has a square cross-section. The clutch head 41 is inserted into and circumferentially positioned with the upper end of the valve stem 3, and the two can slide relative to each other. The electric drive rod 6 has a first engagement hole 6a that can be inserted into and circumferentially positioned with the clutch head 41, and the hand drive rod 5 has a second engagement hole 5a that can be inserted into and circumferentially positioned with the clutch head 41. The second engagement hole 5a is a strip-shaped hole, the width of which is the same as the width of the clutch head 41, and the height of which is greater than the height of the clutch head 41. The first engagement hole 6a and the second engagement hole 5a are located on both sides of the valve stem 3, respectively. By manipulating the outer end of the switching rod 4, the clutch head 41 can be selectively inserted into and circumferentially positioned with one of the first engagement hole 6a and the second engagement hole 5a.

[0032] More specifically, for example Figure 2 and Figure 3 As shown, one side of the main body 1 has a mounting post 1a that protrudes horizontally radially relative to the main body 1. The mounting post 1a has a mounting hole 1a1 inside, and the inner diameter of the mounting hole 1a1 is larger than the maximum outer diameter of the switching rod 4, which facilitates the installation of the switching rod 4. A mounting cap 1b is fitted over and fixed to the mounting post 1a. The outer end of the switching rod 4 extends from the mounting cap 1b through the mounting hole 1a1 and slides with the mounting cap 1b. The middle section of the switching rod 4 has a shoulder 42, and a spring 14 is fitted on the switching rod 4. One end of the spring 14 abuts against the inner side of the mounting cap 1b, and the other end abuts against the shoulder 42. A switching lever 4 is hinged to a switching wrench 7 at its outer end. The switching wrench 7, under the force of a spring 14, is positioned against the outer side of the mounting cap 1b. Rotating the switching wrench 7 allows the switching lever 4 to slide. The bottom of the switching wrench 7 has a limiting surface 71, and the side of the switching wrench 7 has a limiting surface 72 perpendicular to the limiting surface 71. The outer side of the mounting cap 1b has a vertically arranged abutment surface 1b1. When the limiting surface 71 abuts against the abutment surface 1b1, the clutch head 41 is inserted into the engagement hole 6a and circumferentially positioned. When the limiting surface 72 abuts against the abutment surface 1b1, the clutch head 41 is inserted into the engagement hole 5a and circumferentially positioned. For example... Figure 3 and Figure 6 As shown, the upper side of the main body 1 is provided with a ball socket 1c. The lower end of the electric drive rod 6 has a hemispherical connecting part 61, and a connecting hole 6a is provided on the connecting part 61. The end of the hand drive rod 5 opposite to the switching rod 4 is the inner end, and this end has a hemispherical connecting part 51, and a connecting hole 5a is provided on the connecting part 51. The connecting part 61 and the connecting part 51 close together and respectively rotate with the inner wall of the ball socket 1c in the circumferential direction of the switching rod 4. The upper end of the valve rod 3 is located between the connecting part 61 and the connecting part 51. The upper end of the valve rod 3 has a disc-shaped rotating part 31. After the connecting part 61 and the connecting part 51 close together, a rotating cavity adapted to the rotating part 31 is formed inside. The outer peripheral surface of the rotating part 31 fits against the cavity wall of the rotating cavity to form a rotating fit.

[0033] Meanwhile, in this embodiment, as Figure 4 As shown, the main body 1 is also equipped with an electric drive device. The upper end of the electric drive rod 6 is located outside the main body 1 and is driven by the electric drive device. The electric drive device includes a housing 8, a motor 9 fixed inside the housing 8, and a push rod 10 slidably connected to the main body 1 within the housing 8. Wherein, as... Figure 7 As shown, the upper side of the main body 1 has a U-shaped connecting portion 1d, and the housing 8 is covered outside the connecting portion 1d. Mounting notches 81 are respectively provided on both sides of the bottom edge of the housing 8. Screws 13 are inserted into the mounting notches 81, and the housing 8 is locked and fixed to the connecting portion 1d by the screws 13. Figure 4 and Figure 8 As shown, a gear 11 is fixedly connected to the motor shaft of the motor 9. A strip-shaped hole 10a is opened on the push rod 10. A rack 101 is provided on the push rod 10. The rack 101 is located on one side wall of the strip-shaped hole 10a. The gear 11 and the rack 101 are meshed and connected. There are also inwardly protruding and strip-shaped limiting strips 10a1 on both side walls of the strip-shaped hole 10a. The rack 101 is located above the limiting strips 10a1. The lower part of the gear 11 has a cylindrical sliding part 111. The sliding part 111 is located between the two limiting strips 10a1 and slides with the two limiting strips 10a1. A washer 12 is fixedly connected to the lower end surface of the sliding part 111. The washer 12 is located below the limiting strips 10a1 and can slide along the lower surface of the limiting strips 10a1. The upper end of the electric drive rod 6 has a spherical ball head 62, and one end of the push rod 10 has a ball cavity 102 that matches the shape of the ball head 62. The ball head 62 is located inside the ball cavity 102 and the two form a rotational fit.

[0034] The operating principle of this automatic / manual faucet is as follows: When this electronic faucet is in manual mode, such as... Figure 2 As shown, the switching wrench 7 is in a horizontal position, with the clutch head 41 engaged with the second engagement hole 5a of the hand drive lever 5 and disengaged from the first engagement hole 6a of the electric drive lever 6. The user only needs to turn the handle 15, which drives the hand drive lever 5 to rotate, which in turn drives the switching lever 4 to rotate. The switching lever 4 controls the rotation of the upper end of the valve stem 3, thereby controlling the swing of the lower end of the valve stem 3 to achieve the opening and closing control of the valve core 2. When the electronic faucet needs to be switched to electric drive mode, the user only needs to turn the switching wrench 7 until it is in a vertical position. During this process, the switching wrench 7 will pull the switching lever 4 outward, causing the clutch head 41 to exit from the second engagement hole 5a and insert into the first engagement hole 6a. At this time, the electronic faucet is switched to the electric drive mode. Figure 3In the electric drive mode shown, the clutch head 41 is engaged with the engagement hole 6a of the electric drive rod 6 and disengaged from the engagement hole 5a of the hand drive rod 5. In this case, the user only needs to start the motor 9, which will drive the push rod 10 to slide, thereby causing the upper end of the electric drive rod 6 to swing. The switching rod 4 will rotate under the drive of the electric drive rod 6, and then drive the upper end of the valve rod 3 to rotate through the switching rod 4, thereby controlling the lower end of the valve rod 3 to swing and realize the opening and closing control of the valve core 2.
