Description

Technical Field

[0001] This invention relates to the field of faucet technology, and more specifically to an outdoor faucet with a locking function. Background Technology

[0002] A faucet is a common term for a water valve, used to control the flow of water and thus conserve water. Faucets are constantly being updated, evolving from old-fashioned cast iron faucets to electroplated knob faucets, and then to stainless steel single-temperature single-control faucets, stainless steel dual-temperature dual-control faucets, and semi-automatic kitchen faucets. Existing outdoor or public faucets are mostly one-way, especially outdoor faucets, which often only provide cold water and are often multiplied to accommodate multiple users simultaneously, leading to high usage and installation costs. Outdoor faucets are sometimes used by children to play with the water, resulting in water waste. Therefore, faucets need locking devices to shut off the water supply and prevent children from playing with them. Summary of the Invention

[0003] Based on the above problems, the purpose of this invention is to provide a faucet that is easy to use, can supply water from four directions for four people to use at the same time, and can prevent children from playing with water.

[0004] To address the above problems, the following technical solution is provided: An outdoor faucet with a locking function includes a housing and a base detachably connected to the bottom of the housing. It also includes a fixed seat, a first water outlet switch, a first valve plate, a second water outlet switch, a second valve plate, a third water outlet switch, a third valve plate, and a fourth water outlet switch arranged sequentially from bottom to top within the housing. The base has a support column that abuts against the fixed seat, forming a water passage cavity between the base and the fixed seat. The base has an inlet connected to the water passage cavity. The bottom of the base has a connector connected to the inlet. The fixed seat has a first water inlet, a second water inlet, a third water inlet, and a fourth water inlet evenly distributed in its circumferential direction and connected to the water passage cavity. The outer walls of the first water outlet switch, the second water outlet switch, the third water outlet switch, and the fourth water outlet switch are respectively provided with a first connecting pipe, a second connecting pipe, a third connecting pipe, and a fourth connecting pipe penetrating the outer wall of the housing.

[0005] It also includes an opening and closing device, which includes a sealing plate, a movable column, a limiting plate, and a positioning plate. The sealing plate is located between the base and the fixed seat. The sealing plate has a through hole for the support column to pass through. The sealing plate has sealing plugs corresponding to the first water inlet, the second water inlet, the third water inlet, and the fourth water inlet. A water passage groove is opened at the bottom of the sealing plate. A water passage opening is opened on the sealing plate connecting the water passage groove and the water passage cavity. One end of the movable column is connected to the sealing plate, and the other end passes through the fixed seat, the first water outlet switch, the first valve plate, the second water outlet switch, the second valve plate, the third water outlet switch, the third valve plate, the fourth water outlet switch, and the top of the housing. The limiting plate is connected to the top of the movable column. The positioning plate is located above the limiting plate and is fixed to the top of the housing by the fixed column. The limiting plate has a handle. The bottom of the positioning plate has a snap-fit ​​groove adapted to the handle. A locking slot communicating with the snap-fit ​​groove is opened on the outer circle of the positioning plate.

[0006] The bottom of the first water outlet switch is provided with a first water outlet for corresponding connection between the first water inlet and the first connecting pipe; the bottom of the second water outlet switch is provided with a second water outlet for corresponding connection between the second water inlet and the second connecting pipe; the bottom of the third water outlet switch is provided with a third water outlet for corresponding connection between the third water inlet and the third connecting pipe; and the bottom of the fourth water outlet switch is provided with a fourth water outlet for corresponding connection between the fourth water inlet and the fourth connecting pipe.

[0007] The second water inlet is connected to a first water outlet pipe whose top end passes through the first water outlet switch and the first valve plate, and extends to the bottom of the second water outlet switch, communicating with the second water outlet. The third water inlet is connected to a second water outlet pipe whose top end passes through the first water outlet switch, the first valve plate, the second water outlet switch, and the second valve plate, and extends to the bottom of the third water outlet switch, communicating with the third water outlet. The fourth water inlet is connected to a third water outlet pipe whose top end passes through the first water outlet switch, the first valve plate, the second water outlet switch, the second valve plate, the third water outlet switch, and the third valve plate, and extends to the bottom of the fourth water outlet switch, communicating with the fourth water outlet.

[0008] Each of the first, second, third, and fourth water outlet switches has three arc-shaped openings. The arc length of each arc-shaped opening is the stroke of the first, second, third, and fourth water outlet switches relative to their circumferential direction, respectively, to achieve the connection or disconnection of the first inlet and the first outlet, the second inlet and the second outlet, the third inlet and the third outlet, and the fourth inlet and the fourth outlet.

[0009] The first water outlet switch is engaged with the first, second, and third water outlet pipes through an arc-shaped opening; the second water outlet switch is engaged with the second and third water outlet pipes through an arc-shaped opening; and the third water outlet switch is engaged with the third water outlet pipe through an arc-shaped opening.

[0010] The outer wall of the housing is provided with an opening groove that corresponds to and cooperates with the first connecting pipe, the second connecting pipe, the third connecting pipe and the fourth connecting pipe. The top of the opening groove is provided with a positioning groove in the circumferential direction of the housing.

[0011] In the above structure, the present invention is connected to a water supply pipe or drinking water pipe via a connector. Water outlets can be connected to the ends of the first, second, third, and fourth connecting pipes for use. Water enters the water passage groove through the inlet of the connector and then enters the water passage cavity through the outlet, thus the opening and closing device is in the open state. The first, second, third, and fourth water outlet switches are in the closed state, with the outer ends of the first, second, third, and fourth connecting pipes located within positioning grooves. The first, second, third, and fourth water outlets are respectively fitted and sealed to the bottom walls of the first, second, third, and fourth water outlet switches. When the user needs to use the device, they can turn on the faucet according to their current position. Taking the first water outlet switch as an example, the user moves the first connecting pipe, causing it to shift towards the opening of the positioning groove. This rotation of the first water outlet switch, through a curved opening, controls the connection between the first water outlet and the first water inlet. Water enters the first water outlet through the first inlet and flows out from the first connecting pipe. When the first connecting pipe is fully displaced into the opening groove, the first water inlet and the first water outlet are completely connected. The water flow from the first connecting pipe can be controlled by the degree of rotation of the first switch. After use, as the first connecting pipe rotates into the positioning groove, the first water outlet switch rotates circumferentially to fit and seal with the first water inlet. The same steps can be used to open and close the faucet when the user is in a different position or when four users are using it simultaneously. This invention employs a structure that allows water to flow from four directions simultaneously, improving user efficiency, reducing the installation area of ​​the washbasin, and reducing the number of faucets required. This enhances the ease of use and reduces the cost of using this invention. By incorporating an opening and closing mechanism, when needed, the operator can control the handle to pull up the limiting plate, causing the movable column to move the sealing plate upwards until the sealing plug is inserted into each water inlet, cutting off the water supply to each water outlet switch and closing the faucet. Simultaneously, the limiting plate inserts the handle into the locking groove, and a lock passes through the locking hole to lock the handle and positioning plate together. This facilitates operator control of water output, prevents children from playing with the faucet, and conserves water resources. The inclusion of a water passage groove allows water to flow smoothly from the water inlet into the water passage cavity, ensuring smooth flow to each water outlet switch and improving the reliability of the invention. The positioning plate limits the movement of the limiting plate, preventing excessive upward pulling that could damage the faucet, thus improving reliability and extending its service life. The through-hole allows the sealing plate to engage with the support column, improving the stability of the sealing plate during vertical movement and further enhancing the reliability of the invention.By setting an arc-shaped opening, each water outlet switch can be limited, thereby improving the positional accuracy of each water outlet switch during rotation and enhancing the reliability of the invention. The first, second, and third water outlet pipes ensure accurate alignment between the second, third, and fourth water inlets and their corresponding outlets, further improving the stability and reliability of the invention. The first, second, and third valve plates, in cooperation with the first, second, and third water outlet pipes, limit the movement of each water outlet switch, ensuring that the corresponding valve plate does not rotate when the first, second, third, and fourth water outlet switches are rotated, thus improving the stability and reliability of the invention. The open slots facilitate the positioning and installation of the housing and allow for the limitation of the connecting pipes of each switch in the closed state, further enhancing the reliability of the invention.

[0012] The present invention is further configured such that the top of the housing is provided with a limiting groove that is adapted to the limiting plate.

[0013] In the above structure, the limiting groove facilitates the limiting plate's positioning and improves the sealing between the limiting plate and the housing, preventing dust or rainwater from entering the housing from between the housing and the movable column, thereby extending the service life of the invention and improving its reliability.

[0014] The invention is further configured such that the opening groove is provided near the bottom of the housing and has a locking groove opening in the circumferential direction of the housing, and the outer wall of the base is provided with a locking block that matches the locking groove, wherein the arc length of the locking block relative to the circumferential direction of the housing is smaller than the arc length of the opening groove relative to the circumferential direction of the housing.

[0015] In the above structure, the engagement block and the locking groove facilitate easy assembly and disassembly of the base and the housing. Positioning the locking groove at the bottom of the opening reduces the need for slotting, thereby reducing processing steps and improving the production efficiency of this invention.

[0016] The invention is further configured such that the top of the housing is provided with an arc-shaped opening that penetrates one of the corresponding arc-shaped openings on the fourth water outlet switch to a first connecting post that abuts against the top of the third valve plate.

[0017] The present invention is further configured such that the top of the housing is provided with a through arc-shaped port corresponding to one of the fourth water outlet switches, a third valve plate, and a second connecting post that abuts against the top of the second valve plate.

[0018] The present invention is further configured such that the top of the housing is provided with a third connecting post that penetrates one of the corresponding arc-shaped openings on the fourth water outlet switch, the third valve plate, one of the corresponding arc-shaped openings on the third water outlet switch, the second valve plate, and one of the corresponding arc-shaped openings on the second water outlet switch to abut against the top of the first valve plate.

[0019] In the above structure, by setting the first connecting column, the second connecting column, and the third connecting column to correspond and cooperate with the first water outlet pipe, the second water outlet pipe, and the third water outlet pipe, the compactness of the structure of the present invention is improved, the stability of each valve plate is improved, and they play a good limiting role, thereby improving the structural strength and reliability of the present invention.

[0020] The present invention is further configured such that a sealing strip adapted to the opening groove is inserted inside the opening groove.

[0021] The above structure improves the external sealing of the invention and makes the invention more aesthetically pleasing.

[0022] The present invention is further configured such that a sealing ring is embedded at the top end of the first water inlet, the second water inlet, the third water inlet and the fourth water inlet.

[0023] By adopting the above structure, the sealing performance of each water outlet switch and its corresponding water inlet can be increased, thereby improving the reliability and sealing performance of the present invention.

[0024] The present invention is further configured such that the first water outlet switch, the second water outlet switch, the third water outlet switch, the fourth water outlet switch, the fixing base, the first valve plate, the second valve plate, and the third valve plate are all made of ceramic material.

[0025] By adopting the above structure, the sealing performance of the present invention can be further improved, thereby improving the reliability of the present invention. Attached Figure Description

The limiting plate 503 is connected to the top of the movable column 502. The positioning plate 504 is located above the limiting plate 503 and is fixed to the top of the housing 1 through the fixed column 5041. The limiting plate 503 is provided with a handle 5031. The bottom of the positioning plate 504 is provided with a snap-fit ​​groove 5042 that is adapted to the handle 5031. The outer circle of the positioning plate 504 is provided with a locking slot 5043 that communicates with the snap-fit ​​groove 5042.

[0041] The bottom of the first water outlet switch 4 is provided with a first water outlet 42 for corresponding connection between the first water inlet 24 and the first connecting pipe 41; the bottom of the second water outlet switch 6 is provided with a second water outlet 62 for corresponding connection between the second water inlet 25 and the second connecting pipe 61; the bottom of the third water outlet switch 8 is provided with a third water outlet 82 for corresponding connection between the third water inlet 26 and the third connecting pipe 81; and the bottom of the fourth water outlet switch 10 is provided with a fourth water outlet 102 for corresponding connection between the fourth water inlet 27 and the fourth connecting pipe 101.

[0042] The second inlet 25 is connected to a first outlet pipe 251, the top of which passes through the first outlet switch 4 and the first valve plate 5, and the bottom of the second outlet switch 6 is connected to the second outlet 62. The third inlet 26 is connected to a second outlet pipe 261, the top of which passes through the first outlet switch 4, the first valve plate 5, the second outlet switch 6 and the second valve plate 7, and the bottom of the third outlet switch 8 is connected to the third outlet 82. The fourth inlet 27 is connected to a third outlet pipe 271, the top of which passes through the first outlet switch 4, the first valve plate 5, the second outlet switch 6 and the second valve plate 7, the third outlet switch 8 and the third valve plate 9, and the bottom of the fourth outlet switch 10 is connected to the fourth outlet 102.

[0043] The first water outlet switch 4, the second water outlet switch 6, the third water outlet switch 8, and the fourth water outlet switch 10 are each provided with three arc-shaped openings 20. The arc length of the three arc-shaped openings 20 is the stroke of the first water outlet switch 4, the second water outlet switch 6, the third water outlet switch 8, and the fourth water outlet switch 10 relative to their circumferential direction, respectively realizing the connection or disconnection of the first water inlet 24 and the first water outlet 42, the second water inlet 25 and the second water outlet 62, the third water inlet 26 and the third water outlet 82, and the fourth water inlet 27 and the fourth water outlet 102.

[0044] The first water outlet switch 4 is engaged with the first water outlet pipe 251, the second water outlet pipe 261 and the third water outlet pipe 271 through the arc-shaped opening 20; the second water outlet switch 6 is engaged with the second water outlet pipe 261 and the third water outlet pipe 271 through the arc-shaped opening 20; and the third water outlet switch 8 is engaged with the third water outlet pipe 271 through the arc-shaped opening 20.

[0045] The outer wall of the housing 1 is provided with an opening groove 11 that corresponds to and cooperates with the first connecting pipe 41, the second connecting pipe 61, the third connecting pipe 81, and the fourth connecting pipe 101. The top of the opening groove 11 is provided with a positioning groove 111 in the circumferential direction relative to the housing 1.

[0046] In the above structure, the present invention is connected to a water supply pipe or drinking water pipe via connector 23. Water outlets are connected to the ends of the first connecting pipe 41, second connecting pipe 61, third connecting pipe 81, and fourth connecting pipe 101 for use. Water enters the water passage 5013 through the inlet 22 inside connector 23 and then enters the water passage cavity through the outlet 5014, meaning the opening / closing device 50 is in the open state. The first water outlet switch 4, second water outlet switch 6, third water outlet switch 8, and fourth water outlet switch 10 are in the closed state. The outer ends of the first connecting pipe 41, second connecting pipe 61, third connecting pipe 81, and fourth connecting pipe 101 are all located within the positioning groove 111. The first water outlet 42, second water outlet 62, third water outlet 82, and fourth water outlet 102 are respectively fitted and sealed to the bottom walls of the first water outlet switch 4, second water outlet switch 6, third water outlet switch 8, and fourth water outlet switch 10. When the user needs to use it, they can turn on the faucet according to their current position. Taking the first water outlet switch 4 as an example, the user moves the first connecting pipe 41, causing it to move towards the opening of the positioning groove 111, which in turn rotates the first water outlet switch 4. The arc-shaped opening 20 on the first water outlet switch 4 limits the movement, connecting the first water outlet 42 with the first water inlet 24. Water enters the first water outlet 42 through the first water inlet 24 and flows out from the first connecting pipe 41. When the first connecting pipe 41 is fully displaced into the opening groove 11, the first water inlet 24 and the first water outlet 42 are completely connected, allowing the water flow from the first connecting pipe 41 to be controlled by the degree of rotation of the first switch. After the faucet is finished, the user controls the first connecting pipe 41 to rotate into the positioning groove 111, and simultaneously, the first water outlet switch 4 rotates circumferentially to fit and seal with the first water inlet 24. The above steps can be used to open and close the faucet when the user is in another position or when four users are using it simultaneously. This invention employs a structure that allows water to flow simultaneously from four directions, improving user efficiency, reducing the installation area of ​​the washbasin, and minimizing the number of faucets, thus enhancing ease of use and reducing operating costs. The opening and closing device 50 allows the administrator to control the handle 5031 to pull up the limiting plate 503, moving it upwards. This causes the movable column 502 to move the sealing plate 501 upwards until the sealing plug 5012 is inserted into each inlet, cutting off the water supply to each outlet switch and closing the faucet. Simultaneously, the limiting plate 503 inserts the handle 5031 into the locking groove 5042, and the lock passes through the locking slot 5043 to lock the handle 5031 to the positioning plate 504. This facilitates water control by the administrator, prevents children from playing with the faucet, and conserves water resources. The water passage trough 5013 allows water to flow from the inlet 22 through the passage 5014 into the water passage cavity, ensuring smooth water flow to each outlet switch and improving the reliability of the invention.By setting the positioning plate 504, the limiting plate 503 can be limited, preventing excessive upward pulling of the limiting plate 503 and damage to the faucet, thereby improving the reliability of the invention and extending its service life. By setting the through hole 5011, the sealing plate 501 can cooperate with the support column 21, thereby improving the stability of the sealing plate 501 during vertical displacement and improving the reliability of the invention. By setting the arc-shaped through hole 20, each water outlet switch can be limited, thereby improving the positional accuracy of each water outlet switch during rotation and improving the reliability of the invention. By setting the first water outlet pipe 251, the second water outlet pipe 261, and the third water outlet pipe 271, the second water inlet 25, the third water inlet 26, and the fourth water inlet 27 can be accurately aligned with the second water outlet 62, the third water outlet 82, and the fourth water outlet 102, thereby improving the stability and reliability of the invention. The first valve plate 5, the second valve plate 7, and the third valve plate 9 cooperate with the first water outlet pipe 251, the second water outlet pipe 261, and the third water outlet pipe 271 to limit their movement, ensuring that the corresponding valve plates will not rotate when the first water outlet switch 4, the second water outlet switch 6, the third water outlet switch 8, and the fourth water outlet switch 10 are rotated, thereby improving the stability and reliability of the invention. The opening groove 11 facilitates the positioning and installation of the housing 1 and allows for the limiting of the connecting pipes of each switch in the closed state, thus improving the reliability of the invention.

[0047] In this embodiment, the top of the housing 1 is provided with a limiting groove 15 that is adapted to the limiting plate 503.

[0048] In the above structure, the limiting groove 15 facilitates the limiting plate 503 to be positioned, and improves the sealing between the limiting plate 503 and the housing 1, preventing dust or rainwater from entering the housing 1 from between the housing 1 and the movable column 502, thereby extending the service life of the invention and improving the reliability of the invention.

[0049] In this embodiment, the opening slot 11 is provided with a locking groove 112 facing the circumferential direction of the housing 1 at a position near the bottom of the housing 1, and the outer wall of the base 2 is provided with a locking block 28 that is adapted to the locking groove 112. The arc length of the locking block 28 relative to the circumferential direction of the housing 1 is smaller than the arc length of the opening slot 11 relative to the circumferential direction of the housing 1.

[0050] In the above structure, by setting the locking block 28 to cooperate with the locking groove 112, the assembly and disassembly of the base 2 and the housing 1 can be facilitated. Setting the locking groove 112 at the bottom end of the opening groove 11 reduces the number of slots, thereby reducing processing steps and improving the production efficiency of the present invention.

[0051] In this embodiment, the top of the housing 1 is provided with an arc-shaped through-hole 20 that passes through one of the corresponding arc-shaped openings 20 on the fourth water outlet switch 10 to the first connecting post 12 that abuts against the top of the third valve plate 9.

[0052] In this embodiment, the top of the housing 1 is provided with a second connecting post 13 that abuts against the top of the second valve plate 7, through one of the corresponding arc-shaped openings 20 on the fourth water outlet switch 10, the third valve plate 9, and one of the corresponding arc-shaped openings 20 on the third water outlet switch 8.

[0053] In this embodiment, the top of the housing 1 is provided with a third connecting post 14 that passes through one of the corresponding arc-shaped openings 20 on the fourth water outlet switch 10, the third valve plate 9, one of the corresponding arc-shaped openings 20 on the third water outlet switch 8, the second valve plate 7, and one of the corresponding arc-shaped openings 20 on the second water outlet switch 6, and abuts against the top of the first valve plate 5.

[0054] In the above structure, by setting the first connecting post 12, the second connecting post 13, and the third connecting post 14 to correspond and cooperate with the first water outlet pipe 251, the second water outlet pipe 261, and the third water outlet pipe 271, the compactness of the structure of the present invention is improved, the stability of each valve plate is improved, and they play a good limiting role, thereby improving the structural strength and reliability of the present invention.

[0055] In this embodiment, a sealing strip 113 adapted to the opening groove 11 is inserted inside the opening groove 11.

[0056] The above structure improves the external sealing of the invention and makes the invention more aesthetically pleasing.

[0057] In this embodiment, sealing rings are embedded at the top ports of the first water inlet 24, the second water inlet 25, the third water inlet 26, and the fourth water inlet 27.

[0058] By adopting the above structure, the sealing performance of each water outlet switch and its corresponding water inlet can be increased, thereby improving the reliability and sealing performance of the present invention.

[0059] In this embodiment, the first water outlet switch 4, the second water outlet switch 6, the third water outlet switch 8, the fourth water outlet switch 10, the fixing base 3, the first valve plate 5, the second valve plate 7, and the third valve plate 9 are all made of ceramic material.

[0060] By adopting the above structure, the sealing performance of the present invention can be further improved, thereby improving the reliability of the present invention.

[0061] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications assumed above should also be considered within the scope of protection of the present invention.
