Description

Technical Field

[0001] The invention belongs to the technical field of drinking equipment and relates to a manual-automatic electronic faucet. Background Art

[0002] With the advancement of the times and the improvement of people's quality of life, people's expectations for beverages are becoming increasingly higher. For example, canned and bottled beer can no longer meet people's drinking needs. More and more people prefer 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 draw the beer from the barrel to the beer tap, which acts as a switch. When people open the beer tap, beer flows from the tap into the glass, allowing people to drink fresh beer. Therefore, the tap plays a vital role as the final control point for beer dispensing.

[0003] In the prior art, most beer taps are manual. For example, Chinese patent document CN105090586B discloses a tap and its connection structure. The tap includes a valve body with a beer outlet, a valve core slidably disposed within the valve body, and a handle. During use, users simply manually turn the handle to operate the valve core to slide relative to the valve body, thereby controlling the beer outlet and opening and closing the tap. The output volume can also be freely selected according to needs. With people's increasing demand for intelligent control, existing manual taps are no longer able to meet the requirements of intelligent control. To this end, people have developed an electrically controlled faucet based on the existing manual faucet. The electrically controlled faucet is also known as an electronic faucet. This electrically controlled faucet uses a drive motor to control the opening and closing of the faucet. For example, Chinese patent document CN220581792U discloses an electrically controlled faucet assembly, which includes a faucet and a housing. The housing is provided with a drive motor. The faucet includes a faucet body, a joint, and an operating handle. The joint is detachably connected to the faucet body via a locking nut. The joint is fixedly connected to the housing. The faucet body is indirectly connected to the housing via the joint. The housing is provided with a drive arm. The drive arm has a cylindrical drive portion. The drive portion is mounted outside the operating handle. The drive arm can push the operating handle to swing through the drive portion when driven by the drive motor. This electrically controlled faucet assembly realizes the automatic opening and closing of the faucet and has a simple and compact structure.

[0004] However, the above-mentioned electronic faucets still have the following defects in actual use: on the one hand, in order to ensure the compactness of the electronic faucet structure, the battery used for power supply is often small in capacity and has relatively low battery life. In addition, once the battery is low, it cannot be used and needs to be plugged in or fully charged before it can be used, which has poor applicability. On the other hand, in order to avoid the hidden danger of always opening due to accidental pressing or forgetting to close the faucet, based on safety considerations, the flow rate automatic output setting of the above-mentioned electronic faucets is designed to be quantitative. In other words, when using the electronic faucet, the user can only drink according to the output volume designed by the manufacturer. This leads to significant limitations in the use of the electronic faucet, resulting in the user being unable to freely select the output flow rate as needed, and poor applicability. Moreover, even if the hidden danger of always opening is not considered and the quantitative design is cancelled, the user's quantitative output requirement cannot be met. Therefore, in order to make the electronic faucet able to meet the requirements of both free flow output and quantitative output at the same time, the conventional technical means used by those skilled in the art is to switch between the above two modes by designing a control program to improve applicability and ensure the compactness of the original faucet structure. However, the disadvantage of the electronic faucet being unable to be used when it is out of power, resulting in poor applicability, still exists. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a manual-automatic electronic faucet. The technical problem to be solved by the present invention is how to improve the applicability of the electronic faucet while ensuring its compact structure.

[0006] The objectives of the present invention can be achieved through the following technical solutions: a manual-automatic electronic faucet, comprising a body, a valve core arranged in the body, a valve stem arranged vertically on the body and controlling the movement of the valve core by swinging the lower end, characterized in that it also includes a switching rod arranged in the horizontal direction on the same body, a hand-driven rod for manually driving the valve stem to swing and arranged coaxially with the switching rod, and an electric-driven rod for electrically driving the valve stem to swing and arranged vertically, and the three are arranged around the upper end of the valve stem and in a cross layout with the valve stem; the hand-driven rod and the electric-driven rod respectively rotate with the body in the circumferential direction of the switching rod, and the switching rod The outer end of the switch rod extends out of the body, and the inner end of the switch rod has a clutch head that radially protrudes relative to the outer peripheral surface of the inner end and has a non-circular cross-section. The clutch head is plugged into and circumferentially positioned with the upper end of the valve stem, and the two can slide relative to each other. The electric drive rod has a coupling hole 1 that can be plugged into and circumferentially positioned with the clutch head, and the hand drive rod has a coupling hole 2 that can be plugged into and circumferentially positioned with the clutch head. The coupling hole 1 and the coupling hole 2 are respectively located on both sides of the valve stem. By manipulating the outer end of the switch rod to move, the clutch head can be selected to be plugged into and circumferentially positioned with one of the coupling holes 1 and 2.

[0007] The present invention integrates manual mechanical control into the electronic faucet through an ingenious clutch structure design, so that the electronic faucet can be switched into manual and electric control modes, so that the electronic faucet can be used normally even when it is out of power. At the same time, in manual mode, the output flow of the electronic faucet can be selected arbitrarily, and in electric mode, it can meet the demand for quantitative output, thereby completely solving the drawbacks of the existing electronic faucets and comprehensively improving the applicability of the electronic faucet. Moreover, the overall structural design and layout are very ingenious and reasonable, which also ensures the compactness of the electronic faucet structure. Specifically, the present invention improves the existing faucet body and valve core. , and the structure of the valve stem, by integrating the switching rod, the hand-driven rod and the electric-driven rod on the same body of the faucet, wherein the switching rod is used for the clutch switching of the manual and electric driving structures, the hand-driven rod is used to manually drive the valve stem to swing, and the electric-driven rod is used to electrically drive the valve stem to swing, and the switching rod is arranged in the horizontal direction, the hand-driven rod and the switching rod are arranged coaxially, and the electric-driven rod is arranged vertically, and the three are arranged around the upper end of the valve stem and in a cross layout with the valve stem; such a special arrangement of the four rods fully utilizes the radial surrounding space of the faucet body, and the four are combined to form a cross layout, which is tightly arranged to ensure the compactness of the overall structure;

[0008] At the same time, the hand-driven rod and the main body rotate and cooperate in the circumferential direction of the switching rod, the outer end of the switching rod extends out of the main body, and the inner end of the switching rod has a clutch head that radially protrudes relative to the outer circumferential surface of the inner end and has a non-circular cross-section. The clutch head is plugged into and circumferentially positioned with the upper end of the valve stem and the two can slide relative to each other. The electric drive rod has a combining hole 1 that can be plugged into and circumferentially positioned with the clutch head, and the hand-driven rod has a combining hole 2 that can be plugged into and circumferentially positioned with the clutch head. The combining hole 1 and the combining hole 2 are respectively located on both sides of the valve stem. After this design, people only need to manipulate the outer end of the switching rod to move to enable the clutch head to select one of the combining hole 1 and the combining hole 2 for plugging and circumferential positioning. When the clutch head is switched to select and match with the first combination hole, the clutch head and the second combination hole are in a disengaged state. At this time, the switching rod and the hand-driven rod are not linked, but are linked with the electric drive rod. Since the electric drive rod and the body rotate in the circumferential direction of the switching rod, at this time, it is only necessary to electrically drive the electric drive rod to rotate relative to the body, which will synchronously drive the switching rod to rotate, and then the switching rod will drive the upper end of the valve stem to rotate, thereby finally driving the lower end of the valve stem to swing, so as to realize the opening of the valve core, that is, the faucet is in the electric drive mode; when the clutch head is switched to select and match with the second combination hole, the clutch head and the first combination hole are in a disengaged state. At this time, the switching rod and the electric drive rod are not linked, but are linked with the hand-driven rod. Since the hand-driven rod and the body are in the cutting direction, the electric drive rod The circumferential rotation of the switching rod is coordinated. At this time, it is only necessary to manually drive the hand-driven rod to rotate relative to the main body, which will synchronously drive the switching rod to rotate, and then the switching rod drives the upper end of the valve stem to rotate, thereby finally driving the lower end of the valve stem to swing, so as to realize the opening of the valve core, that is, the faucet is in manual drive mode; therefore, through the coordinated design of the above switching rod, hand-driven rod, electric drive rod and valve stem, the faucet can be switched to manual and electric control modes. When the faucet is out of power, it can be switched to manual drive mode to work, which completely solves the disadvantage that the existing electronic faucet cannot be used when it is out of power. In addition, the faucet can meet any output demand of flow, thereby comprehensively improving the applicability of the faucet.

[0009] In the aforementioned manual-automatic electronic faucet, the clutch head has a square cross-section, and the second coupling hole is a strip-shaped, waist-shaped hole. The width of the second coupling hole is consistent with the width of the clutch head, and the height of the second coupling hole is greater than the height of the clutch head. Due to the above-mentioned shape design of the clutch head and the second coupling hole, since the clutch head and the second coupling hole are only limited by two surfaces, the clutch head is less likely to get stuck when plugged into the second coupling hole, and the coupling is smoother, thereby facilitating the clutch and automatic switching of the electronic faucet, thereby ensuring smooth switching between manual and automatic operation, thereby effectively improving the applicability of the electronic faucet.

[0010] In the aforementioned manual-automatic electronic faucet, one side of the body has a mounting post that protrudes horizontally and radially relative to the body, the mounting post having a mounting hole therein, a mounting cap disposed on the outer surface of the mounting post and fixedly connected thereto, the outer end of the switching lever extending from the mounting cap through the mounting hole and slidingly engaging with the mounting cap, the middle section of the switching lever having a boss, and a spring sleeved on the switching lever, one end of the spring resting on the inner side of the mounting cap and the other end resting on the boss. The above design, on the one hand, eliminates the need to overcome the spring action when manipulating the switching lever to move, and the spring also provides a reset force for the movement of the switching lever, thereby improving the feel and safety of the switching lever clutch operation; on the other hand, the design of the mounting post that provides installation space for the switching lever rationally utilizes the radial space of the faucet body, and the design of the spring sleeved on the switching lever helps ensure the compactness of the faucet structure.

[0011] In the above-mentioned manual-automatic electronic faucet, the outer end of the switching rod is hinged with a switching wrench, and the switching wrench is positioned against the outer side of the mounting cap under the action of spring force. By rotating the switching wrench, the switching rod can be pulled to slide; the bottom of the switching wrench has a limiting surface 1, and the side of the switching wrench has a limiting surface 2 perpendicular to the limiting surface 1. The outer side of the mounting cap has an abutment surface arranged vertically. When the limiting surface 1 is positioned against the abutment surface, the clutch head is plugged into the coupling hole 1 and circumferentially positioned; when the limiting surface 2 is positioned against the abutment surface, the clutch head is plugged into the coupling hole 2 and circumferentially positioned. Through the design of the above switching wrench, the switching rod can be manipulated to move by simply rotating the switching wrench, making the manual and automatic switching operations of the faucet simple and convenient, thereby ensuring that the faucet can meet the operating requirements of both manual and electric modes, thereby ensuring the improvement of the applicability of the faucet.

[0012] In the above-mentioned manual-automatic electronic faucet, a ball socket is provided on the upper side of the main body, the lower end of the electric drive rod has a hemispherical joint part 1, the joint hole 1 is provided on the joint part 1, the end of the hand-driven rod opposite to the switching rod is the inner end, and the end has a hemispherical joint part 2, the joint hole 2 is provided on the joint part 2, the joint part 1 and the joint part 2 are closed together and respectively cooperate with the inner wall of the ball socket in the circumferential rotation of the switching rod, and the upper end of the valve stem is located between the joint part 1 and the joint part 2. Through the above-mentioned design of the shape of the electric drive rod and the hand-driven rod and the position arrangement of the two and the valve stem, the connection and cooperation positions of the three are concentrated at the ball socket. While ensuring the rotation function of each of the three, the structure of the three is very compact when combined together, thereby improving the applicability of the electronic faucet while ensuring the compact structure of the electronic faucet.

[0013] In the aforementioned manual-automatic electronic faucet, the upper end of the valve stem is a circular rotating portion. When the first and second joints are closed, a rotating cavity is formed internally that is compatible with the rotating portion. The outer circumference of the rotating portion is in contact with the cavity wall of the rotating cavity to form a rotating fit. This design allows the electric drive lever and the manual drive lever to serve two purposes. While ensuring their respective basic functions, they also provide a mechanism for the rotation of the upper end of the valve stem, enabling stable rotation of the valve stem. Furthermore, this combination makes the structure of the three more compact, thereby improving the applicability of the electronic faucet while maintaining its compact structure.

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

[0015] In the above-mentioned manual-automatic electronic faucet, a strip-shaped hole is provided on the push rod, the rack is located on one side wall of the strip-shaped hole, and the two side walls of the strip-shaped hole also have inwardly protruding and strip-shaped limit strips. The rack is located above the limit strip and the two are parallel. The lower part of the gear has a cylindrical sliding portion, the sliding portion is located between the two limit strips and slides with the two limit strips. A gasket is fixed to the lower end surface of the sliding portion, the gasket is located below the limit strip and can slide along the lower surface of the limit strip. Through the above-mentioned design of the limit strip and the sliding portion, the two can provide a guide for the sliding of the push rod, so that the sliding of the push rod is more stable; through the gasket and its design of cooperation with the limit strip, on the one hand, the gear is not easy to loosen, and on the other hand, the gasket can slide along the lower surface of the limit strip, which is also conducive to improving the stability of the push rod sliding. The improvement of the push rod sliding stability is conducive to better electric control of the swing of the electric drive rod, making the electric drive mode of this faucet reliable.

[0016] In the aforementioned manual-automatic electronic faucet, the upper end of the electric drive rod has a spherical ball head, and one end of the push rod has a ball cavity that matches the shape of the ball head. The ball head is located within the ball cavity, and the two form a rotational fit. Through the design of the ball head and ball cavity, the push rod and the electric drive rod are able to work in a coordinated manner. This structure is very convenient for assembly and disassembly, and the structure is relatively compact.

[0017] In the aforementioned manual-automatic electronic faucet, the upper side of the body has a U-shaped connection portion, the housing cover is positioned outside the connection 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 connection portion via the screws. This design allows the housing to be disassembled simply by removing the screws, while the remaining components related to the electric drive are integrated into the housing. In other words, removing the housing is equivalent to removing the entire electric drive device, making cleaning and disassembly of the faucet body very convenient.

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

[0019] 1. This electronic faucet has two control modes: manual and electric. This allows the faucet to be used normally even when there is a power outage. At the same time, the manual mode can meet the user's demand for arbitrary flow output, and the electric mode can meet the user's demand for quantitative output, which is very suitable.

[0020] 2. The overall structural design and layout of this electronic faucet are very sophisticated, making the overall structure of the electronic faucet very compact. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0031] Specifically, if Figure 1 and Figure 4 As shown, the manual-automatic electronic faucet comprises a body 1, a valve core 2 provided in the body 1, and a valve stem 3 vertically provided on the body 1 and controlling the movement of the valve core 2 by swinging the lower end. Figure 2 and Figure 3 As shown, the manual-automatic electronic faucet further includes a switching lever 4 arranged in the horizontal direction on the same body 1, a hand-driven lever 5 for manually driving the valve stem 3 to swing and coaxial with the switching lever 4, and an electric driving lever 6 for electrically driving the valve stem 3 to swing and arranged in the vertical direction. Figure 5 As shown, the switch rod 4, electric drive rod 6, and electric drive rod 6 are arranged around the upper end of the valve stem 3 and in a cross-shaped layout with the valve stem 3. Among them, the manual drive rod 5 and the electric drive rod 6 are respectively rotated with the body 1 in the circumferential direction of the switch rod 4. The outer end of the manual drive rod 5 extends out of the body 1 and is fixedly connected to a handle 15 perpendicular to the manual drive rod 5. The outer end of the switch rod 4 extends out of the body 1, and the inner end of the switch rod 4 has a clutch head 41 that protrudes radially relative to the outer circumference of the inner end and has a non-circular cross-section, as shown in FIG. Figure 6As shown, in this embodiment, the cross-section of the clutch head 41 is square. The clutch head 41 is plugged into the upper end of the valve stem 3 and is circumferentially positioned and can slide relative to each other. The electric drive rod 6 has a coupling hole 1 6a that can be plugged into and circumferentially positioned with the clutch head 41, and the manual drive rod 5 has a coupling hole 2 5a that can be plugged into and circumferentially positioned with the clutch head 41. The coupling hole 2 5a is a strip-shaped waist-shaped hole. The width of the coupling hole 2 5a is consistent with the width of the clutch head 41, and the height of the coupling hole 2 5a is greater than the height of the clutch head 41. The coupling hole 1 6a and the coupling hole 2 5a are respectively located on both sides of the valve stem 3. By manipulating the outer end of the switching rod 4 to move, the clutch head 41 can be selected to be plugged into and circumferentially positioned with one of the coupling holes 1 6a and 2 5a.

[0032] More specifically, Figure 2 and Figure 3 As shown, one side of the body 1 has a mounting post 1a protruding horizontally and radially relative to the body 1. Within this post 1a is a mounting hole 1a1. The inner diameter of the mounting hole 1a1 is larger than the maximum outer diameter of the switching lever 4, facilitating installation of the switching lever 4. A mounting cap 1b is disposed over and fixedly attached to the mounting post 1a. The outer end of the switching lever 4 extends from the mounting cap 1b through the mounting hole 1a1 and slidably engages with the mounting cap 1b. The midsection of the switching lever 4 has a shoulder 42. A spring 14 is sleeved over the switching lever 4, with one end of the spring 14 resting against the inner side of the mounting cap 1b and the other end resting against the shoulder 42. The outer end of the switching rod 4 is hinged with a switching wrench 7, which is positioned against the outer side of the mounting cap 1b under the action of the elastic force of the spring 14. The switching rod 4 can be pulled to slide by rotating the switching wrench 7. The bottom of the switching wrench 7 has a limiting surface 1 71, and the side of the switching wrench 7 has a limiting surface 2 72 perpendicular to the limiting surface 1 71. The outer side of the mounting cap 1b has a vertically arranged abutting surface 1b1. When the limiting surface 1 71 is abutted against the abutting surface 1b1, the clutch head 41 is plugged into the coupling hole 1 6a and circumferentially positioned. When the limiting surface 2 72 is abutted against the abutting surface 1b1, the clutch head 41 is plugged into the coupling hole 2 5a and circumferentially positioned. For example Figure 3 and Figure 6 As shown, the upper side of the body 1 is provided with a ball socket 1c, the lower end of the electric drive rod 6 has a hemispherical joint 1 61, and the joint hole 1 6a is provided on the joint 1 61. The end of the manual drive rod 5 opposite to the switching rod 4 is the inner end, and this end has a hemispherical joint 2 51, and the joint hole 2 5a is provided on the joint 2 51. The joint 1 61 and the joint 2 51 are closed together and respectively cooperate with the inner wall of the ball socket 1c in the circumferential rotation of the switching rod 4. The upper end of the valve stem 3 is located between the joint 1 61 and the joint 2 51. The upper end of the valve stem 3 is a round pancake-shaped rotating portion 31. When the joint 1 61 and the joint 2 51 are closed, a rotating cavity is formed inside to match the rotating portion 31. The outer peripheral surface of the rotating portion 31 is in contact with the cavity wall of the rotating cavity to form a rotating fit.

[0033] At the same time, in this embodiment, Figure 4 As shown, the body 1 is also provided with an electric drive device, the upper end of the electric drive rod 6 is located outside the faucet body 1 and is driven by the electric drive device; the electric drive device includes a housing 8, a motor 9 fixed in the housing 8, and a push rod 10 slidably connected to the housing 8 along the axial direction of the body 1. Figure 7 As shown, the upper side of the body 1 has a U-shaped connecting portion 1d, the shell 8 is covered outside the connecting portion 1d, and the two side edges of the bottom of the shell 8 are respectively provided with mounting notches 81, and screws 13 are passed through the mounting notches 81. The shell 8 is 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, and 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, and the gear 11 and the rack 101 are meshed and connected. The side walls on both sides of the strip-shaped hole 10a also have inwardly protruding and strip-shaped limit strips 10a1, and the rack 101 is located above the limit strip 10a1. The lower part of the gear 11 has a cylindrical sliding portion 111, and the sliding portion 111 is located between the two limit strips 10a1 and slidably cooperates with the two limit strips 10a1. A gasket 12 is fixedly connected to the lower end surface of the sliding portion 111, and the gasket 12 is located below the limit strip 10a1 and can slide along the lower surface of the limit strip 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 in the ball cavity 102 and the two form a rotational fit.

[0034] The operating principle of this manual-automatic electronic faucet is as follows: When the electronic faucet is in manual drive mode, Figure 2 As shown, the switching wrench 7 is in the horizontal direction, the clutch head 41 is plugged into the second coupling hole 5a of the hand-driven rod 5, and is disengaged from the first coupling hole 6a of the electric-driven rod 6. The user only needs to bend the handle 15, and the handle 15 drives the hand-driven rod 5 to rotate, and the hand-driven rod 5 then drives the switching rod 4 to rotate. The upper end of the valve stem 3 can be controlled to rotate through the switching rod 4, thereby controlling the swing of the lower end of the valve stem 3 to realize the opening and closing control of the valve core 2; when the electronic faucet needs to be switched to the electric drive mode, the user only needs to rotate the switching wrench 7 until the switching wrench 7 is in a vertical state. During this process, the switching wrench 7 will pull the switching rod 4 to move outward, so that the clutch head 41 withdraws from the second coupling hole 5a and is inserted into the first coupling 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 plugged into the coupling hole 1 6a of the electric drive rod 6 and disengaged from the coupling hole 2 5a of the manual drive rod 5. In this case, the user only needs to start the motor 9, and the motor 9 can drive the push rod 10 to slide, thereby driving the upper end of the electric drive rod 6 to swing. The switching rod 4 rotates under the drive of the electric drive rod 6, and then drives the upper end of the valve stem 3 to rotate through the switching rod 4, thereby controlling the swing of the lower end of the valve stem 3 to realize the opening and closing control of the valve core 2.
