Technical Field

[0001] This invention relates to the field of bathroom equipment technology, and in particular to a concealed faucet. Background Technology

[0002] In existing technologies, wall-mounted faucets typically have the faucet body fixed to the wall, with the water outlet exposed. When not in use, the faucet's prolonged exposure not only takes up space but also makes it susceptible to impacts, water stains, or dust, affecting its cleanliness and lifespan. Summary of the Invention

[0003] The purpose of this invention is to provide a concealed faucet that allows for easy storage of the faucet body and convenient operation.

[0004] To achieve this objective, the present invention adopts the following technical solution: Concealed faucets include: The main storage unit has storage compartments; A water supply assembly includes a faucet body and a water supply pipe. The faucet body is movably connected to the receiving body and has a receiving state and an extended state relative to the receiving cavity. In the receiving state, the faucet body is located in the receiving cavity and disconnected from the water supply pipe. In the extended state, the faucet body extends out of the receiving cavity and is connected to the water supply pipe. The locking mechanism can lock the faucet body to the storage body when the faucet body is in the storage state; pressing the faucet body can drive the locking mechanism to unlock or lock the faucet body. A driving component, disposed in the storage body, is capable of driving the faucet body to extend out of the storage cavity.

[0005] In some embodiments, the faucet body is rotatably connected to the storage body, the first connector of the water supply pipe is provided with an opening, the second connector of the faucet body is provided with a water inlet, the first connector and the second connector are coaxially arranged and rotatably connected, when the faucet body is in the storage state, the water inlet is disconnected from the opening, and when the faucet body is in the extended state, the water inlet is connected to the opening.

[0006] In some embodiments, the faucet body rotates relative to the storage body between 0° and a first preset angle, the faucet body is in the storage state at 0° and in the extended state at the first preset angle; When the faucet body rotates within a range greater than or equal to 0° and less than or equal to a second preset angle, the water inlet and the opening are disconnected, wherein the second preset angle is less than the first preset angle. When the faucet body rotates within a range greater than the second preset angle and less than the first preset angle, the water inlet and the opening are partially connected. When the faucet body is at the first preset angle, the water inlet and the opening are fully connected.

[0007] In some embodiments, the first connector includes a tubular body and a cup, the tubular body is provided with a partition, the cup passes through the partition, and the cup is provided with the opening; The end face of the diaphragm and the second connector with the water inlet abuts against each other; and / or, the second connector is sleeved on the first connector, and a sealing ring is provided between the outer side wall of the first connector and the inner side wall of the second connector.

[0008] In some embodiments, the openings are provided in a plurality of annularly distributed locations, and the inlets are provided in a plurality of annularly distributed locations. The shapes of the openings and the inlets are the same, and the two can be connected in a one-to-one correspondence.

[0009] In some embodiments, an inlet and outlet are provided on one side of the storage body, and the faucet body passes through the inlet and outlet to rotate into and out of the storage cavity.

[0010] In some embodiments, the locking mechanism includes a locking component and a reset component. When the faucet body is subjected to force, the locking component can be driven to unlock or lock the faucet body, and the reset component drives the locking component to lock the faucet body to the storage body.

[0011] In some embodiments, the faucet body is provided with a first protrusion, the lock assembly includes a base, a hook, a slider and a pawl, the slider is slidably connected to the base, the slider is provided with a sliding groove, the sliding groove has a first stop position and a second stop position, one end of the hook is connected to the base, and the other end is slidably disposed in the sliding groove, a rotating shaft and a second protrusion are provided on one side of the slider, and the pawl is rotatably connected to the rotating shaft; The first protrusion can drive the hook to repeatedly hook onto the first stop position and the second stop position by pushing against the second protrusion; When the hook is engaged in the first stop position, the pawl is positioned between the base and the slider, and the pawl abuts against the outside of the first protrusion to lock the first protrusion. When the hook is engaged in the second stop position, the slider drives the claw to extend out of the base, and the reset component drives the claw to unlock the first protrusion.

[0012] In some embodiments, the reset component includes: A first elastic element is connected between the base and the slider. The first elastic element has the tendency to drive the slider to move inward, so that the hook is hooked at the second stop position. The second elastic element is connected between the claw and the slider. When the hook is engaged in the first stop position, the claw rotates to a position limited between the slider and the base, and the second elastic element deforms. When the hook is engaged in the second stop position, the claw disengages from the base, the second elastic element elastically resets, and drives the claw to unlock the first protrusion.

[0013] In some embodiments, a buffer is further included, connected between the storage body and the faucet body, wherein the piston rod of the buffer retracts as the faucet body moves from the stored state to the extended state; the drive member is connected between the storage body and the faucet body and has a tendency to drive the piston rod of the buffer to retract.

[0014] The beneficial effects of this invention are: This invention provides a concealed faucet. When the faucet body is outside the storage cavity, pressing the faucet body moves it into the storage cavity, where a locking mechanism then locks it in place. During this movement, the faucet body disconnects from the water supply pipe, thus disconnecting the water flow and keeping the faucet body in a retracted and disconnected state, achieving a concealed effect and a cleaner overall appearance. Pressing the faucet body again unlocks the locking mechanism, and the faucet body moves out of the storage cavity under the action of a driving component, extending into the extended state. During this movement, the faucet body connects to the water supply pipe, maintaining the extended and connected state, thus enabling water to flow. With the coordinated action of the storage body, faucet body, drive component, and locking mechanism, pressing the faucet body drives the locking mechanism to lock and unlock the faucet body in a cycle. That is, pressing the faucet body locks the faucet body and simultaneously hides it in the storage cavity and disconnects the water circuit; pressing the faucet body again unlocks the faucet body and simultaneously extends the faucet body out of the storage cavity and connects the water circuit. Thus, the storage and water dispensing actions are linked, requiring no additional operation and making it easy to use. Attached Figure Description

[0017] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] like Figures 1-6As shown, this embodiment provides a concealed faucet, including a storage body 1, a water channel assembly 2, a locking mechanism 4, and a driving component 3. The storage body 1 has a storage cavity 101; the water channel assembly 2 includes a faucet body 21 and a water supply pipe 22. The faucet body 21 is movably connected to the storage body 1 and has a stored state and an extended state relative to the storage cavity 101. In the stored state, the faucet body 21 is located in the storage cavity 101 and disconnected from the water supply pipe 22. In the extended state, the faucet body 21 extends out of the storage cavity 101 and is connected to the water supply pipe 22. When the faucet body 21 is in the stored state, the locking mechanism 4 can lock the faucet body 21 to the storage body 1. Pressing the faucet body 21 can drive the locking mechanism 4 to unlock or lock the faucet body 21. The driving component 3 is disposed in the storage body 1 and can drive the faucet body 21 to extend out of the storage cavity 101.

[0021] When the faucet body 21 is outside the storage cavity 101, pressing the faucet body 21 moves it into the storage cavity 101, and then the locking mechanism 4 locks the faucet body 21. During the movement, the faucet body 21 is disconnected from the water supply pipe 22 to disconnect the water path, so that the faucet body 21 remains in the stored and disconnected state, achieving a hidden effect and a simpler overall appearance. Pressing the faucet body 21 again unlocks the faucet body 21, and under the action of the driving component 3, the faucet body 21 moves to the outside of the storage cavity 101 to be in the extended state. During the movement, the faucet body 21 is connected to the water supply pipe 22 to connect the water path, so that the faucet body 21 remains in the extended and connected state, realizing water flow. With the coordinated action of the storage body 1, the faucet body 21, the driving component 3, and the locking mechanism 4, pressing the faucet body 21 drives the locking mechanism 4 to cycle through unlocking and locking the faucet body 21. That is, pressing the faucet body 21 locks the faucet body 21 and simultaneously hides it in the storage cavity 101 and disconnects the water circuit. Pressing the faucet body 21 again unlocks the faucet body 21 and simultaneously extends it out of the storage cavity 101 and connects it to the water circuit. By pressing the faucet body 21, the storage / extension and water shut-off / outflow actions are linked together with a single action, requiring no additional operation and making it more convenient.

[0022] like Figures 1-3 and Figure 8As shown, the faucet body 21 is rotatably connected to the receiving body 1. The first connector 221 of the water supply pipe 22 has an opening 2214; the second connector 211 of the faucet body 21 has a water inlet 212. The first connector 221 and the second connector 211 are coaxially arranged and rotatably connected. When the faucet body 21 is in the receiving state, the water inlet 212 is disconnected from the opening 2214. When the faucet body 21 is in the extended state, the water inlet 212 is connected to the opening 2214. No additional valve or other structure is required between the first connector 221 and the second connector 211. The on / off state is achieved by rotation itself, which is simple in structure and only requires a certain rotation angle to switch on / off, making the operation simple. By rotatably connecting the faucet body 21 to both the receiving body 1 and the water supply pipe 22, the stability of the faucet body 21's movement is ensured. During rotation, the receiving and water shut-off are achieved simultaneously, or the extension and water discharge are achieved simultaneously.

[0023] In one embodiment, the faucet body 21 has a flow channel inside, and its side wall is provided with an inlet 212 and an outlet, which are connected through the flow channel, resulting in a simple and compact structure. Furthermore, the top side wall of the faucet body 21 is rotatably connected to the storage body 1 by a pin, which extends vertically. The inlet 212 and the outlet are both located on the bottom side wall of the faucet body 21, and the second connector 211 is tubularly protruding from the bottom side wall of the faucet body, and the second connector 211 is arranged around the outer periphery of the inlet 212.

[0024] A water supply pipe 22 is located inside the receiving cavity 101 and includes a pipe and a first connector 221. The pipe is installed on the receiving body 1, with one end connected to an external water pipe and the other end connected to the first connector 221. The first connector 221 includes a tubular body 2211 and a cup 2213. The tubular body 2211 is provided with a partition 2212, and the cup 2213 passes through the partition 2212. The cup 2213 is provided with an opening 2214. Specifically, the partition 2212 is provided with an installation groove, and the cup 2213 is snapped into the installation groove. The first connector 221 and the second connector 211 are arranged vertically. The second connector 211 is located above the first connector 221 and is sleeved on the first connector 221. The axes of the first connector 221 and the second connector 211 are collinear with the axis of the pin. The water supply pipe 22 rotates around the axis parallel to the vertical direction, thereby causing the faucet body 21 to rotate on the horizontal plane to screw into or out of the receiving cavity 101.

[0025] The end faces of the inlet 212 on the leather cup 2213 and the second connector 211 abut against each other. The leather cup 2213 is a bowl-shaped elastic sealing element made of nitrile rubber or silicone rubber, which has good elasticity. The leather cup 2213 elastically abuts against the bottom side wall of the faucet body 21, and relies on elastic deformation to achieve a sealing connection at the end face when the first connector 221 and the second connector 211 rotate. A sealing ring 23 is provided between the outer side wall of the first connector 221 and the inner side wall of the second connector 211 to achieve a circumferential sealing connection between the first connector 221 and the second connector 211. By setting the leather cup 2213 and the sealing ring 23, the rotational sealing connection of the first connector 221 and the second connector 211 is achieved to prevent water leakage.

[0026] Optionally, a control valve 24 is installed on the water supply pipe 22, which can realize water shut-off and water outlet. Furthermore, it can also realize cold water regulation, hot water regulation, and flow rate regulation. Water outlet is regulated by both the control valve 24 and the rotating faucet body 21, which has good reliability. For example, the control valve 24 is a single-handle hot and cold water mixing valve.

[0027] Optionally, an aerator 214 is installed at the water outlet. The aerator 214 is an existing structure and can be referred to in the existing technology, so it will not be described in detail.

[0028] The faucet body 21 rotates relative to the storage body 1 between 0° and a first preset angle. At 0°, the faucet body 21 is in a retracted state, and at the first preset angle, it is in an extended state. By rotating between 0° and the first preset angle, the movement path of the faucet body 21 is set as a unique path, facilitating structural layout and preventing structural interference. Setting 0° and the first preset angle as limit points ensures proper retraction and extension, facilitating control. When the faucet body 21 is in the retracted state, its side can be retracted to a position flush with the wall, facilitating manual contact and pressing. In one embodiment, the first preset angle is 90°, meaning the faucet body 21 rotates between 0° and 90°, resulting in a short movement path and facilitating quick switching between the retracted and extended states. In the extended state, i.e., when in use, the water outlet of the faucet body 21 is closest to the user, making it convenient to use.

[0029] When the faucet body 21 rotates within a range greater than or equal to 0° and less than or equal to a second preset angle, the inlet 212 and the opening 2214 are disconnected, wherein the second preset angle is less than the first preset angle. When the faucet body 21 rotates within a range greater than the second preset angle and less than the first preset angle, the inlet 212 and the opening 2214 are partially connected. When the faucet body 21 rotates outward from 0° to the second preset angle, or when the faucet body 21 rotates inward from the second preset angle to 0°, the faucet body 21 and the water supply pipe 22 are both disconnected. When the faucet body 21 rotates outward from the second preset angle to the first preset angle, or when the faucet body 21 rotates inward from the first preset angle to the second preset angle, the faucet body 21 and the water supply pipe 22 are both connected. In one embodiment, the second preset angle is 60°, meaning that the faucet body 21 automatically starts dispensing water when rotated to approximately 60°, and the opening 2214 and the inlet 212 are connected between 60° and 90°, with the inlet 212 and the opening 2214 occupying 30° of the circumference. This avoids the second preset angle being too small, causing water to be dispensed too early during the rotation of the faucet body 21, resulting in water waste; it also avoids the second preset angle being too large, causing the proportion of the inlet 212 and the opening 2214 along the circumference to be too small, thus affecting the water output. The specific size of the inlet 212 and the opening 2214, as well as the size of the first preset angle and the second preset angle, can be set according to actual needs and are not limited.

[0030] Multiple openings 2214 are provided and are evenly distributed in a ring, as are multiple inlets 212. The shapes of the openings 2214 and the inlets 212 are the same, and they can be connected one-to-one. When multiple openings 2214 and multiple inlets 212 are connected simultaneously, the maximum flow rate can be increased, and the flow velocity can be made more stable. In one embodiment, two openings 2214 and two inlets 212 are provided.

[0031] like Figure 1 and Figure 2As shown, in one embodiment, the storage body 1 is an independent component. The water channel assembly 2, locking mechanism 4, and driving component 3 are all installed on the storage body 1. The concealed faucet is installed as an independent component on the wall or embedded in a groove in the wall. Specifically, the storage body 1 includes a base 11, a bottom plate 12, a panel 13, and a housing 14. The bottom plate 12 is fixed to the housing 14 by screws or other fasteners, and the two form a storage cavity 101. The base 11 is fixed to the bottom plate 12 and is located inside the storage cavity 101. The faucet body 21 and the water supply pipe 22 are both connected to the base 11 by screws or other fasteners. The panel 13 is installed on the bottom plate 12 and located outside the storage cavity 101, serving a decorative purpose. The panel 13 and the base plate 12 are perforated with an inlet / outlet 102 and a slot 103. Specifically, the inlet / outlet 102 is located on one side of the main housing 1. The faucet body 21 passes through the inlet / outlet 102 and screws into and out of the housing cavity 101, thus exposing the faucet body 21 only through the inlet / outlet 102. In the retracted state, the faucet body 21 is sealed within the inlet / outlet 102, concealing other internal structures of the main housing 1 for a more aesthetically pleasing appearance. Furthermore, one inner side of the inlet / outlet 102 acts as a stop, preventing the faucet body 21 from rotating excessively and maintaining it in the optimal water outlet position. The control valve 24 is installed on the water supply pipe 22 via the slot 103, and its knob is located externally for easy operation.

[0032] In another embodiment, the storage body 1 is part of the wall, and the wall has a storage cavity 101 and an inlet / outlet 102; or, the wall has a groove, and a baffle plate is embedded at the groove opening, thereby forming the storage cavity 101 together, and the baffle plate has an inlet / outlet 102.

[0033] like Figures 4-6 As shown, the locking mechanism 4 includes a locking component 41 and a reset component 42. When the faucet body 21 is subjected to force, it can drive the locking component 41 to unlock or lock the faucet body 21. The reset component 42 drives the locking component 41 to lock the faucet body 21 to the storage body 1. This means that pressing the faucet body 21 once locks it with the locking mechanism 4, and pressing it again unlocks it. The faucet body 21 will automatically pop out under the action of the driving component 3. By repeatedly pressing the faucet body 21, the locking component 41 can switch between unlocking and locking without requiring any additional operation on the locking mechanism 4.

[0034] In one embodiment, the faucet body 21 is provided with a first protrusion 213, and the locking assembly 41 includes a base 411, a hook 412, a slider 413, and a pawl 414. The slider 413 is slidably connected to the base 411, and a sliding groove 4133 is provided on the slider 413. The sliding groove 4133 has a first stop position 4134 and a second stop position 4135. One end of the hook 412 is connected to the base 411, and the other end is slidably disposed in the sliding groove 4133. A rotating shaft 4131 and a second protrusion 4132 protrude from one side of the slider 413, and the pawl 414 is rotatably connected to the rotating shaft 413. 31; The first protrusion 213, by pushing against the second protrusion 4132, can drive the hook 412 to cyclically hook onto the first stop position 4134 and the second stop position 4135; when the hook 412 is hooked onto the first stop position 4134, the pawl 414 is limited between the base 411 and the slider 413, and the pawl 414 abuts against the outside of the first protrusion 213, locking the first protrusion 213; when the hook 412 is hooked onto the second stop position 4135, the slider 413 drives the pawl 414 to extend out of the base 411, and the reset assembly 42 drives the pawl 414 to unlock the first protrusion 213. The base 411 is fixed to the base plate 12.

[0035] The reset assembly 42 includes a first elastic element 421 and a second elastic element 422. The first elastic element 421 is connected between the base 411 and the slider 413. The first elastic element 421 has the tendency to drive the slider 413 to move inward, so that the hook 412 is hooked at the second stop position 4135. Optionally, the first elastic element 421 is a linear spring. The slider 413 is provided with a guide post. The linear spring is sleeved on the guide post, and the two ends of the linear spring abut against the base 411 and the slider 413 respectively.

[0036] The second elastic element 422 is connected between the jaw 414 and the slider 413. When the hook 412 is engaged in the first stop position 4134, the jaw 414 rotates to a limit position between the slider 413 and the base 411, and the second elastic element 422 deforms. When the hook 412 is engaged in the second stop position 4135, the jaw 414 disengages from the base 411, the second elastic element 422 elastically resets, and drives the jaw 414 to unlock the first protrusion 213. Optionally, the second elastic element 422 is a torsion spring, which is sleeved on the rotating shaft 4131, and its two ends abut against the jaw 414 and the slider 413 respectively.

[0037] like Figure 6As shown, the sliding groove 4133 is annular with a heart-shaped cross-section, specifically comprising a first arc segment and a second arc segment symmetrically arranged on both sides. The two arc segments are connected to form a tip and a top. The first stop 4134 is located at the top, and the second stop 4135 is located at the tip. The first stop 4134 is located above the second stop 4135. From the first stop 4134 to the second stop 4135, the depth of the first arc segment first increases and then gradually decreases due to the inclined bottom of the groove; the depth of the second arc segment first decreases and then gradually increases due to the inclined bottom of the groove; the depth of the first stop 4134 is less than the depth of the first arc segment but greater than the depth of the second arc segment; the second stop 4135 is located on the second arc segment, and its depth is greater than the depth of the first arc segment.

[0038] Optionally, the steps of locking and unlocking the faucet body 21 by pressing the faucet body 21 include: When the faucet body 21 is in the locked state, the hook 412 is hooked at the first stop position 4134, the first elastic element 421, i.e., the linear spring, is in the initial state, the pawl 414 is limited between the slider 413 and the base 411, the second elastic element 422, i.e., the torsion spring, is in the compressed state, and the pawl 414 abuts against the outside of the first protrusion 213 of the faucet body 21, restricting the faucet body 21 from rotating outward. At this time, the second protrusion 4132 on the base 411 is located inside the first protrusion 213.

[0039] Pressing the faucet body 21 causes the first protrusion 213 to push against the second protrusion 4132, causing the slider 413 to move inward. Through the groove shape and depth of the sliding groove 4133, the hook 412 slides along the first arc section of the sliding groove 4133 to the second stop position 4135, thereby causing the slider 413 to move outward. The pawl 414 disengages from the base 411. Without the restraint of the base 411, the pawl 414 rotates to separate from the first protrusion 213 under the reset action of the second elastic element 422, i.e., the torsion spring, thus unlocking. At this time, the first elastic element 421 is in a stretched state.

[0040] Afterwards, the first elastic element 421 resets, the slider 413 moves inward, the hook 412 slides along the second arc section of the sliding groove 4133 to the first stop position 4134, the claw 414 is again limited between the base 411 and the slider 413, and the second elastic element 422 is compressed to store energy.

[0041] Pressing the faucet body 21 again causes it to rotate from the outside to the inside of the storage cavity 101, driving the claw 414 to rotate inward. This causes the second elastic element 422 to continue to be compressed and store energy until the first protrusion 213 passes over the claw 414 and is located outside the second protrusion 4132. Pressing the faucet body 21 then stops. After that, the second elastic element 422 returns to the position where the claw 414 abuts against the outside of the first protrusion 213 of the faucet body 21, and the locking mechanism 4 locks the faucet body 21 again.

[0042] Through the coordinated action of the base 411, hook 412, slider 413 and claw 414 in the locking assembly 41, and the first elastic element 421 and the second elastic element 422 in the reset assembly 42, the locking mechanism 4 can be locked and unlocked by pressing the faucet body 21.

[0043] like Figure 4 and Figure 5 As shown, in one embodiment, the pawl 414 has a locking protrusion 4141, and the base 411 has a step 4111. When the faucet body 21 is in the locked state, with the pawl 414 confined between the slider 413 and the base 411, the locking protrusion 4141 is located on the upper surface of the step 4111. The pawl 414 is supported on the upper surface of the step 4111 by the locking protrusion 4141, increasing the height of the pawl 414 so that it can abut against the first protrusion 213. When the faucet body 21 is in the unlocked state, the slider 413 moves outward until the pawl 414 disengages from the base 411. The locking protrusion 4141 is located on the side of the step 4111. The pawl 414 loses the support of the locking protrusion 4141, resulting in a decrease in height, allowing the first protrusion 213 to pass over the pawl 414, thus unlocking the faucet. In addition, the locking protrusion 4141 is confined to the side of the step 4111 to prevent the pawl 414 from rotating excessively and losing control. Furthermore, the protrusion 4141 is provided with a guide surface for engaging with the step 4111, facilitating sliding from the side of the step 4111 to the upper surface of the step 4111.

[0044] like Figure 4 and Figure 5 As shown, in one embodiment, the hook 412 is U-shaped, including a main body and bent portions connected to both ends of the main body. One bent portion is fixedly connected to the base 411, and the other bent portion is slidably connected to the sliding groove 4133, and can hook 412 at the first stop position 4134 and the second stop position 4135. A third elastic member 415, such as a spring, is provided between the base 411 and the main body. The spring abuts against the base 411 and the main body, so that the hook 412 is tightly pressed against the sliding groove 4133 to prevent it from detaching.

[0045] like Figure 2As shown, in one embodiment, the driving component 3 is a torsion spring, and the faucet body 21 is connected to the base 11 inside the storage cavity 101 via the torsion spring; one end of the torsion spring is connected to the base 11, and the other end is connected to the faucet body 21, giving it a tendency to rotate outward from the storage cavity 101. In the storage state, the locking mechanism 4 locks the faucet body 21, causing the torsion spring to be in a compressed and deformed state, thus storing energy; when the locking mechanism 4 is unlocked, the torsion spring resets, and under the action of elastic force, it drives the faucet body 21 to rotate to the outside of the storage cavity 101.

[0046] The concealed faucet also includes a buffer 5, which is connected between the storage body 1 and the faucet body 21. During the movement of the faucet body 21 from the stored state to the extended state, the piston rod of the buffer 5 retracts to provide cushioning. The drive component 3 is connected between the storage body 1 and the faucet body 21 and has a tendency to drive the piston rod of the buffer 5 to retract, thus allowing the faucet body 21 to slowly pop out. In one embodiment, the buffer 5 is a hydraulic buffer. The cylinder of the hydraulic buffer is rotatably connected to the base 11, and the piston rod and the drive component 3 (i.e., the torsion spring) are both rotatably connected to the same pin on the faucet body 21. When the faucet body 21 is in the stored and locked state, the torsion spring is in a compressed state, and the piston rod of the hydraulic buffer (which has a built-in automatic extension spring) is in an extended state. After the faucet body 21 is unlocked, the torsion spring continuously releases energy, causing the faucet body 21 to rotate and extend, and the piston rod of the hydraulic buffer is continuously compressed, thus providing cushioning.

[0047] like Figures 7-10 As shown, the faucet body 21 is located in the storage cavity 101 and is in a stored state. The overall appearance is minimalist. At this time, the drive component 3, i.e., the torsion spring, is in a compressed state. The hook 412 is hooked on the first stop position 4134, so that the pawl 414 abuts against the outside of the first protrusion 213 of the faucet body 21, realizing the locking mechanism 4 locking the faucet body 21. The opening 2214 of the leather cup 2213 is offset from the water inlet 212 of the faucet body 21, and the water supply pipe 22 is disconnected from the faucet body 21, i.e., it is in the water-off state.

[0048] like Figure 11 and Figure 12 As shown, after pressing the faucet body 21, the locking mechanism 4 works. At this time, the hook 412 is hooked into the second stop position 4135, and the slider 413 moves so that the pawl 414 rotates under the elastic force of the second elastic element 422 until it disengages from the first protrusion 213 of the faucet body 21.

[0049] like Figure 13 and Figure 14 As shown, under the combined action of the drive component 3, namely the torsion spring and the hydraulic damper, the faucet body 21 automatically and slowly springs open to the second preset angle, such as 60°. At this time, the opening 2214 of the leather cup 2213 gradually overlaps with the water inlet 212 of the faucet body 21, and water begins to flow out.

[0050] like Figure 15 and Figure 16 As shown, when the faucet body 21 rotates to 90°, it is stopped by an inner side of the inlet / outlet 102. At this time, the drive component 3, i.e., the torsion spring, is in its initial open state, and the piston rod of the hydraulic damper is compressed to its lowest point. The opening 2214 of the diaphragm cup 2213 completely overlaps with the inlet 212 of the faucet body 21, and the water flow reaches its maximum, initiating water output. When the faucet body 21 is closed, the opposite action is performed until one working cycle is completed; the specific details are not elaborated further.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
