Description

Technical Field

[0001] This utility model relates to the field of hot water cup technology, and in particular to a portable electric hot water cup with a hidden drain outlet. Background Technology

[0002] Currently, the location of the water dispensing spout on hot water cups is usually fixed, meaning the spout is always exposed to the external environment. This means that even when water is not needed, the spout remains exposed, making it easy for dust to accumulate and pollute the water. At the same time, the exposed spout can easily become a breeding ground for bacteria, mold, and other microorganisms, and long-term accumulation may affect the user's health. Utility Model Content

[0003] The main purpose of this invention is to propose a portable electric hot water cup with a concealed drain outlet, which aims to improve the problem that the water outlet of current hot water cups is easily contaminated because it is always exposed.

[0004] To achieve the above objectives, this utility model proposes a portable electric hot water cup with a concealed drain outlet, comprising:

[0005] A shell, wherein the shell contains a water tank;

[0006] A heating element, disposed within the housing, is used to heat the water tank; and

[0007] A water intake component is movably mounted on the housing. The water intake component has an extended position that extends outward from the housing and a retracted position that retracts into the housing. The water intake component is connected to the water tank, and the water intake component is in the extended position for discharging water outward.

[0008] In one embodiment, at least a portion of the outer peripheral side of the housing is recessed inward toward the water tank to form a groove;

[0009] One end of the water intake component is rotatably installed in the groove, and the other end has a drain outlet for draining water to the outside.

[0010] When the water intake component is in the extended position, the drain outlet moves outward from the groove; when the water intake component is in the retracted position, the drain outlet retracts into the groove.

[0011] In one embodiment, the water intake assembly includes:

[0012] The box body, one end of which is rotatably mounted within the groove; and

[0013] A transfer compartment is located inside the box. The drain outlet is located at the end of the transfer compartment away from the rotation axis of the box. The end of the transfer compartment close to the rotation axis of the box has a water inlet, which is connected to the water tank.

[0014] In one embodiment, the portable electric hot water cup with a concealed drain outlet further includes a suction component disposed within the housing, the suction component being connected between the water tank and the water inlet, for driving the water in the water tank to be discharged outward through the water intake component.

[0015] In one embodiment, the water intake assembly further includes a flow-blocking component, which is disposed in the transfer chamber and located on the side close to the water inlet. On the water flow path, the flow-blocking component is positioned opposite the drain outlet.

[0016] A water-passing space is formed between the flow-blocking component and the wall of the transfer compartment, allowing water to flow through the water-passing space and pass over the flow-blocking component.

[0017] In one embodiment, when the water intake assembly is in the deployed position, the drain outlet is formed on the bottom wall of the transfer chamber in the height direction of the housing;

[0018] The water intake assembly also includes a flow guide located in the transfer chamber. The flow guide is arranged in a spiral shape, and a water-passing area is formed between two adjacent spiral structures of the flow guide. The axial center line of the flow guide coincides with the axial center line of the drain outlet.

[0019] In the height direction of the guide member, a channel is provided through the guide member, and the water passage area is connected to the transfer chamber and the channel, so that water flows through the water passage area into the channel and is discharged through the drain outlet.

[0020] In one embodiment, the depth of the transfer chamber gradually increases from the inlet to the outlet.

[0021] In one embodiment, the box body is rotatably mounted in the groove via a pivot.

[0022] The housing has a locking element to lock the pivot when the housing is in the unfolded position or the retracted position.

[0023] In one embodiment, at least one end of the rotating shaft away from the box body extends into the housing, and the circumference of the end of the rotating shaft extending into the housing is provided with an unfolding locking groove and a retracting locking groove at intervals.

[0024] The locking element includes:

[0025] A locking rod is provided, movable in the height direction of the housing; the locking rod is inserted into the unfolded locking groove to lock the box in the unfolded position; the locking rod is also inserted into the retracted locking groove to lock the box in the retracted position; and

[0026] An elastic element is disposed between the locking rod and the housing to drive the locking rod into the unfolding locking groove when the box moves to the unfolded position; and to drive the locking rod into the retracting locking groove when the box moves to the retracted position.

[0027] In one embodiment, the bottom of the locking rod has a locking block, and in the rotation direction of the shaft, both ends of the locking block are formed with inclined surfaces.

[0028] This utility model relates to a portable electric hot water cup with a concealed drain outlet. The cup includes a shell, a water tank, a suction component, and a heating element. A water dispensing component is movably arranged on the shell and is connected to the water tank via the suction component. The water dispensing component has a retracted position within the shell and an extended position extending outwards. When water is needed, the water dispensing component is extended outwards from the shell, activating the suction component and dispensing water through the drain outlet. When water is not needed, the water dispensing component is moved from the extended position to the retracted position, thus retracting the drain outlet within the shell. This provides a relatively sealed environment for the drain outlet, preventing contamination from the external environment when water is not needed, and improving the hygiene and safety of the hot water cup.

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0054] The location of the water dispensing spout on most hot water cups is usually fixed, meaning it is always exposed to the external environment. This means that even when water is not needed, the spout remains exposed, making it easy for dust to accumulate and pollute the water. At the same time, the exposed spout can easily become a breeding ground for bacteria, mold, and other microorganisms, and long-term accumulation may affect the user's health.

[0055] Based on this, refer to Figure 1 , Figure 2 , Figure 5 As shown, this application embodiment provides a portable electric hot water cup with a concealed drain outlet, including a shell 1, a water tank 2, a heating element 4, and a water dispensing assembly 5; wherein, the water tank 2 is located inside the shell 1 and is fixedly installed inside the shell 1, and the water tank 2 is used to store water; the heating element 4 is located inside the shell 1 and is used to heat the water in the water tank 2; the water dispensing assembly 5 is movably installed on the shell 1, and the water dispensing assembly 5 has an extended position that extends outward from the shell 1 and a retracted position that retracts into the shell 1, when the user needs to dispense water, the water dispensing assembly 5 is driven to move from the retracted position to the extended position. The extended position is used to complete the water dispensing process; when the user does not need to dispense water, the water dispensing component 5 is driven to move from the extended position to the retracted position, thereby causing the water dispensing component 5 to retract into the housing 1, providing a relatively sealed environment for the water dispensing component 5, thus improving the hygiene and safety of the hot water cup; the portable electric hot water cup with a hidden drain also includes a suction component 6, which is located inside the housing 1 and connects to the water tank 2 and the water dispensing component 5. The suction component 6 is used to draw water out of the water tank 2 and drain it out through the water dispensing component 5; it is understood that, as Figure 1 Figure 2 As shown, the top of the water tank 2 has an opening 21 that communicates with the outside, allowing the user to add water to the water tank 2 through the opening 21. The portable electric hot water cup with a hidden drain also includes a top cover 3, which is movably positioned at the opening 21 for opening or closing the opening 21.

[0056] In this embodiment, the suction component 6 can be a water pump to ensure that the flow of water is completely controlled. For example, one end of the water pump is connected to the water tank 2, and the other end is connected to the water intake component 5. When the user needs to take water, the water pump is started to draw water out of the water tank 2 and discharge it through the water intake component 5 in its deployed position. It is understood that the water pump has an inlet and an outlet, such as... Figure 5As shown, the water inlet is connected to the bottom of the water tank 2 via the first pipe 61, and the water outlet is connected to the water intake component 5 via the second pipe 62. Since the water intake component 5 is movably arranged on the housing 1, in order to accommodate the movable arrangement of the water intake component 5, the second pipe 62 connecting the water outlet and the water intake component 5 needs to be set as a flexible pipe, such as a silicone hose, which has the characteristics of high temperature resistance, chemical resistance and good flexibility, and is used to accommodate the position adjustment of the water intake component 5.

[0057] It is understood that the water pump in this solution has normally open and normally closed states. In the normally open state, the control circuit or valve of the water pump is open when there is no external control signal or power supply. In the normally closed state, the control circuit or valve of the water pump is closed when there is no external control signal or power supply. This ensures that when the water pump is powered on and started, the above-mentioned pipeline is in a conductive state, and when the water pump is powered off and stops working, the above-mentioned pipeline is in a non-conductive state.

[0058] In this embodiment, the suction component 6 can be powered by a power source located inside the housing 1 or by an external power source; for example, a battery 9 can be arranged at a suitable location inside the housing 1, and the battery 9 is used to power the suction component 6; Figure 1 , Figure 2 As shown, a control panel is located at the top of the housing 1, which integrates some control operation buttons. The housing 1 also integrates control circuit boards and other related control modules (all powered by battery 9). Users can perform corresponding operations through the control panel, such as controlling the suction component 6 to start and pump water through the control buttons on the control panel. Since the above control methods are all existing technologies, they will not be described in detail here.

[0059] In this embodiment, as Figure 5 As shown, the heating element 4 is fitted to the bottom wall of the water tank 2 to heat the water in the water tank 2; exemplarily, a specific structure of the heating element 4 is provided, such as... Figure 12 As shown, the heating element 4 includes a ceramic substrate 41, on which a heating element is provided. The ceramic substrate 41 can be fixed to the bottom wall of the water tank 2 and is in close contact with the bottom wall of the water tank 2. When the electrical circuit of the heating element is connected to an external power source, the heating element generates heat and transfers the heat through the wall of the water tank 2 to the water in the water tank 2, thereby realizing the heating process. It is understood that the material of the water tank 2 needs to be a food-grade material with good thermal conductivity and strong corrosion resistance, such as aluminum alloy, stainless steel, etc. Good thermal conductivity can quickly transfer the heat generated by the heating element to the water, resulting in high heating efficiency. Strong corrosion resistance can provide good resistance to minerals and chemicals in the water, resulting in a long service life.

[0060] It is understood that the ceramic substrate 41 can be fixed to the bottom wall of the water tank 2 by means of adhesive or fasteners. When adhesive is used, curing silicone can be used to bond it to the bottom wall of the water tank 2. Curing silicone has good thermal conductivity and can remain stable at high temperatures. At the same time, curing silicone has good electrical insulation properties, which can prevent leakage and improve safety. It is understood that before bonding, the bottom wall of the water tank 2 and the surface of the ceramic heating element need to be thoroughly cleaned to remove oil, dust and other impurities. Alcohol or special cleaning agents can be used for cleaning.

[0061] Furthermore, the heating element described above can be a DC heating element 42 or an AC heating element 43, such as... Figure 3 , Figure 4 As shown, the housing 1 is provided with a DC socket 421 that is electrically connected to the DC heating unit 42 and an AC socket 431 that is electrically connected to the AC heating unit 43. They are connected to an external power connector through their respective sockets, so that the portable electric water heater with a hidden drain can be used with a 220V household AC power supply or a 12-24V DC vehicle power supply. This significantly improves the applicability of the portable electric water heater with a hidden drain.

[0062] In this embodiment, if the battery 9 is built into the housing 1 and used to power the suction component 6, it can be connected to an external power connector through the DC socket 421 provided on the housing 1, thereby achieving the effect of charging the battery 9; it should be noted that the charging operation is not performed when the battery 9 is working.

[0063] In this embodiment, the housing 1 includes an outer shell and a frame. The frame is located inside the outer shell and is fixedly installed with the outer shell, thereby constituting the housing 1. The water tank 2 is installed inside the frame. Figure 4 As shown in the figure, after the outer shell is removed, the positional relationship between the frame and the water tank 2 is illustrated. The suction component 6 and the battery 9 are both fixedly installed on the outer periphery of the frame, thereby providing reliable support for the installation of the suction component 6 and the battery 9.

[0064] Reference Figure 1 , Figure 3 As shown, in one embodiment of this application, at least a portion of the outer peripheral side of the shell 1 is recessed inward toward the water tank 2 to form a groove 11; one end of the water intake component 5 is rotatably installed in the groove 11, and the other end has a drain outlet 5211 for draining water to the outside; when the water intake component 5 is in the unfolded position, the drain outlet 5211 moves outward from the groove 11; when the water intake component 5 is in the retracted position, the drain outlet 5211 retracts into the groove 11.

[0065] In this embodiment, the groove 11 is provided on the housing 1, and the groove 11 extends along the height direction of the housing 1, such as... Figure 2 As shown, when water intake is not required, the water intake component 5 is positioned within the groove 11 (in the retracted position), thereby retracting the drain outlet 5211 on the water intake component 5 into the groove 11 and providing a relatively sealed environment for the drain outlet 5211, preventing contamination of the drain outlet 5211 by the external environment when water intake is not needed; Figure 3 As shown, when water needs to be taken, the water taking component 5 is driven to rotate relative to the groove 11 and extend outward from the groove 11, thereby exposing the drain outlet 5211 to the external environment, and then used to realize the water taking process.

[0066] In this embodiment, as Figure 2 As shown, in order to facilitate the user's operation of rotating the water-taking component 5 relative to the groove 11, the length of the groove 11 can be set to be greater than the length of the water-taking component 5 in the height direction of the housing 1. This ensures that when the water-taking component 5 is in the retracted position, there is still a certain distance between the bottom of the water-taking component 5 and the bottom of the groove 11 in the height direction of the housing 1. This allows the user to reach into the space between the water-taking component 5 and the bottom of the groove 11 to pull the water-taking component 5 out of the groove 11 and rotate it to the unfolded position, thereby realizing the water-taking operation.

[0067] Reference Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, in one embodiment of this application, the water intake component 5 includes a housing 51 and a transfer chamber 52; wherein, one end of the housing 51 is rotatably mounted in the groove 11, and the transfer chamber 52 is fixedly disposed inside the housing 51, as shown. Figure 9 As shown, the drain outlet 5211 is located at the end of the transfer chamber 52 away from the rotation axis of the box body 51, and the end of the transfer chamber 52 near the rotation axis of the box body 51 is provided with a water inlet 5212. It can be understood that the water inlet 5212 is connected to the suction component 6 through the second pipe 62. The second pipe 62 connecting the water inlet 5212 and the suction component 6 is a flexible silicone hose, so as to cooperate with the adjustment of the transfer chamber 52 as the box body 51 rotates, ensuring that the water inlet 5212 can always be connected to the suction component 6 through the above-mentioned flexible pipe.

[0068] In this embodiment, as Figure 8 As shown, the box body 51 includes a first housing 512 and a first cover 511. One end of the first housing 512 is rotatably mounted in the groove 11, and the first cover 511 covers the upper end of the first housing 512 to seal it. For example, the first cover 511 and the first housing 512 can be connected by a snap-fit ​​connection or by fasteners. Figure 8 As shown, in this embodiment, a snap-fit ​​bracket is provided on the bottom periphery of the first cover 511, and a snap-fit ​​hole is provided on the snap-fit ​​bracket. A snap-fit ​​block that mates with the snap-fit ​​hole is provided on the periphery wall inside the first housing 512. Thus, the first cover 511 is snapped and fixed to the first housing 512 through the snap-fit ​​engagement of the above structure. Figure 8 As shown, a notch 5121 is provided at one end of the first housing 512 near its rotation axis, thereby allowing the flexible tube connected to the water outlet of the suction component 6 to extend into the housing 51 through the notch 5121 and communicate with the water inlet 5212 provided on the transfer chamber 52.

[0069] In this embodiment, when a user needs to collect water, the box 51 needs to be moved from the retracted position to the unfolded position so that the drain outlet 5211 moves out of the groove 11. Then, the suction component 6 is activated, thereby drawing water from the water tank 2 into the transfer chamber 52 through the first pipe 61, the second pipe 62, and the inlet 5212 in sequence, and then discharging it out from the drain outlet 5211, thus realizing the water collection process.

[0070] It is understandable that the size of the notch 5121 should be set so that when the box 51 rotates between the unfolded and retracted positions, the flexible tube can be adjusted within the notch 5121 without touching other structural components, thus avoiding unnecessary wear.

[0071] In this embodiment, as Figure 3 , Figure 7 As shown, holes (not shown in the figure) need to be made at the corresponding positions of the first box 512 and the drain outlet 5211 to allow water in the transfer chamber 52 to be discharged outward through the drain outlet 5211 and the holes on the first box 512.

[0072] Reference Figure 9 , Figure 10 , Figure 11 As shown, in one embodiment of this application, the water intake assembly 5 further includes a flow-blocking component 53. The flow-blocking component 53 is installed inside the transfer chamber 52, and is located on the side near the water inlet 5212. On the water flow path, the flow-blocking component 53 is positioned opposite the drain outlet 5211. Figure 9 As shown, a water passage space 531 is formed between the flow-blocking member 53 and the wall of the transfer chamber 52, which is used to allow water to flow through the water passage space 531 and over the flow-blocking member 53.

[0073] In this embodiment, the transfer chamber 52 includes a second housing 521 and a second cover 522. An inlet 5212 and a drain 5211 are both formed on the second housing 521. The inlet 5212 is formed on the side of the second housing 521 near the rotation axis of the housing 51, and the drain 5211 is formed on the bottom wall of the second housing 521. The second cover 522 is placed over the upper end of the second housing 521 to seal it, thereby preventing leakage when water moves within the transfer chamber 52. It should be noted that the second cover 522 and the second housing 521... Sealing measures, such as rubber ring seals or ultrasonic seals, are required at the connection between 21. In this embodiment, ultrasonic sealing is used. Ultrasonic sealing is a technology that uses ultrasonic energy to connect and seal materials. Its core principle is to use the heat generated by high-frequency vibration to locally melt and recombine the material (usually thermoplastic) to achieve a seal. This improves the sealing performance of the transfer chamber 52. The second cover 522 and the second box 521 can be connected and fixed by adhesive or by other fasteners.

[0074] In this embodiment, as Figure 9 As shown, the flow-blocking component 53 is fixedly installed on the second cover 522, and the bottom of the flow-blocking component 53 is spaced a certain distance from the bottom wall of the second box 521, so that a water-passing space 531 is formed between the flow-blocking component 53 and the bottom wall of the transfer chamber 52. This allows the water to be buffered to a certain extent when it enters the transfer chamber 52 through the water inlet under the suction of the suction component 6, thereby controlling the speed of the water flow and preventing water splashing when the water with excessive flow velocity is discharged from the drain outlet 5211.

[0075] In this embodiment, when water enters the transfer chamber 52 from the inlet 5212 and hits the flow-blocking member 53, it passes through the water-passing space 531 between the flow-blocking member 53 and the bottom wall of the transfer chamber 52 and moves towards the drain outlet 5211, and is finally discharged outward through the drain outlet 5211. It can be understood that the two sides of the flow-blocking member 53 and the two side walls of the transfer chamber 52 can also be set at a certain distance, that is, except for the top wall of the transfer chamber 52, the other three inner side walls of the transfer chamber 52 are all separated from the flow-blocking member 53 by a certain distance, and the above-mentioned interval forms the water-passing space 531, thereby improving the water transport efficiency.

[0076] Reference Figure 9 , Figure 11As shown, in one embodiment of this application, when the water intake component 5 is in the unfolded position, a drain outlet 5211 is formed on the bottom wall of the transfer chamber 52 in the height direction of the shell 1, that is, on the bottom wall of the second box 521. Thus, when the user takes water, the water flows from top to bottom along the height direction of the shell 1. The water intake component 5 also includes a hollow guide member 54 disposed in the transfer chamber 52 (a channel is provided through the guide member 54 in the height direction of the guide member 54). The guide member 54 is arranged in a spiral shape, and a water passage area 541 is formed between two adjacent spiral structures of the guide member 54. The water passage area 541 is connected to the transfer chamber 52 and the channel, so that the water flows through the water passage area 541 into the channel inside the guide member 54 and is discharged through the drain outlet 5211. The axial center line of the guide member 54 coincides with the axial center line of the drain outlet 5211, that is, the channel and the drain outlet 5211 are corresponding.

[0077] In this embodiment, a guide 54 is provided in the transfer chamber 52 and at the location corresponding to the drain outlet 5211. This can further improve the buffering effect on the water flow. After the water flow is blocked by the flow-blocking member 53, its speed has been initially reduced to a certain extent. When the water flow moves to the guide 54 in the transfer chamber 52, it is further buffered by the buffering and guiding effect of the guide 54. This causes the water that originally entered the transfer chamber 52 from the inlet 5212 and had a relatively fast flow to be converted into a slow flow. As a result, when the water is discharged vertically outward through the drain outlet 5211, there will be no splashing, ensuring the stability and safety of the water output.

[0078] For example, the guide member 54 in this embodiment can be a spring, such as... Figure 9 , Figure 11 As shown, the gap between two adjacent spiral structures on the spring forms a water passage zone 541. When the water flows to the guide member 54, it will pass through the water passage zone 541 and enter the interior of the spring. Then, it will be discharged vertically outward through the drain outlet 5211. During the process of the water flow entering the interior of the spring, it is buffered by multiple spiral structures on the spring, which further reduces the flow rate of the water flow and forms a slow flow, so as to ensure that the water can be discharged outward from the drain outlet 5211 at a slower flow rate.

[0079] In this embodiment, as Figure 9 , Figure 10 As shown, a slot is provided at the bottom of the second housing 521 for accommodating and limiting the flow guide 54, and a limiting cylinder 5221 is provided on the second cover 522, so that the bottom of the flow guide 54 is inserted into the slot and the top of the flow guide 54 is sleeved on the outer periphery of the limiting cylinder 5221, thereby limiting and fixing the flow guide 54 in the transfer chamber 52, ensuring that the flow guide 54 can be stably installed in the transfer chamber 52.

[0080] Reference Figure 9 As shown in one embodiment of this application, the depth of the transfer chamber 52 gradually increases from the inlet 5212 to the outlet 5211. This causes the cross-sectional size of the water flow section within the transfer chamber 52 to gradually increase from the inlet 5212 to the outlet 5211. The increase in the cross-sectional size of the water flow section can further reduce the flow velocity of the water when it moves within the transfer chamber 52. This allows the water to flow out at a relatively slow speed when it is discharged through the outlet 5211, so as to avoid splashing and ensure water intake safety.

[0081] Reference Figure 6 , Figure 7 , Figure 8 As shown, in one embodiment of this application, the box body 51 is rotatably installed in the groove 11 via the rotating shaft 7. In the width direction of the box body 51, the two sides of the box body 51 are respectively connected to the rotating shaft 7 and are rotatably installed in the groove 11 via the rotating shaft 7. A locking member 8 is provided inside the housing 1 to lock and position the rotating shaft 7 when the box body 51 is in the retracted position or the unfolded position, so as to ensure that the water intake component 5 can be stably maintained in the retracted position or stably maintained in the unfolded position.

[0082] In this embodiment, a locking member 8 is provided inside the housing 1 to lock and position the water-taking component 5 when it is in the retracted or extended position, thereby ensuring the stability of the water-taking component 5 regardless of whether it is in the retracted or extended position. When the water-taking component 5 is in the retracted position, it is locked and positioned by the locking member 8 to ensure that the water-taking component 5 will not easily move out of the groove 11 due to external force or contact. At the same time, when the water-taking component 5 is in the extended position and taking water, the locking member 8 locks and positions the water-taking component 5 to ensure the smooth progress of the water taking process, so as to prevent the water-taking component 5 from shaking unnecessarily during the water taking process, which would cause water to spill out and ensure the stability of the water flow.

[0083] Reference Figure 6 , Figure 7 , Figure 8 As shown, in one embodiment of this application, at least part of the end of the rotating shaft 7 away from the housing 51 extends into the housing 1, such as... Figure 6 The rotating shaft 7, extending into the housing 1, has an expansion locking groove 71 and a retraction locking groove 72 spaced apart on its circumferential side; as... Figure 6 , Figure 7 As shown, the locking member 8 includes a locking rod 81 and an elastic member 82; wherein, in the height direction of the housing 1, the locking rod 81 is movably arranged inside the housing 1, and the locking rod 81 is located above the rotating shaft 7; when the locking rod 81 is inserted into the unfolding locking groove 71, it is used to lock and position the box 51 in the unfolded position; when the locking rod 81 is inserted into the retracting locking groove 72, it is used to lock and position the box 51 in the retracted position; as shown Figure 7As shown, the elastic element 82 is connected between the housing 1 and the locking rod 81. That is, one end of the elastic element 82 presses against the locking rod 81, and the other end presses against the inside of the housing 1. Thus, the elastic element 82 applies a force to the locking rod 81 that always has a downward tendency. When the box 51 moves from the unfolded position to the retracted position, the retracted locking groove 72 provided on the rotating shaft 7 moves just below the locking rod 81, and the locking rod 81 is inserted downward into the retracted locking groove 72 under the action of the elastic element 82, thereby locking and positioning the box 51 in the retracted position. When the box 51 moves from the retracted position to the unfolded position, the unfolded locking groove 71 provided on the rotating shaft 7 moves just below the locking rod 81, and the locking rod 81 is inserted downward into the unfolded locking groove 71 under the action of the elastic element 82, thereby locking and positioning the box 51 in the unfolded position.

[0084] It is understandable that the size of the center angle between the unfolding locking groove 71 and the retracting locking groove 72 determines the position of the water intake component 5 when it is in the retracted or unfolded position. In this embodiment, in order to facilitate the water intake operation, so that when the water intake component 5 is in the unfolded position, it is kept in a horizontal state, and when the water intake component 5 is in the retracted position, it can be completely retracted into the groove 11 and kept in a vertical state, so the center angle between the unfolding locking groove 71 and the retracting locking groove 72 can be set to 90°, that is, the rotation angle of the water intake component 5 from the unfolded position to the retracted position or from the retracted position to the unfolded position is 90°.

[0085] In this embodiment, as Figure 6 As shown, a guide structure (not shown in the figure) is also provided inside the housing 1 to restrict the locking rod 81 from moving along the height direction of the housing 1, so that the locking rod 81 can move stably along the height direction of the housing 1 inside the housing 1, so as to ensure the smooth realization of the locking process of the water intake component 5.

[0086] It is understood that in this embodiment, the elastic element 82 can be a spring, which is sleeved on the outer periphery of the locking rod 81, with one end pressing against the locking rod 81 and the other end pressing against the corresponding position inside the housing 1.

[0087] Reference Figure 6 , Figure 7As shown, in one embodiment of this application, the bottom of the locking rod 81 has a locking block 811, and in the rotation direction of the rotating shaft 7, the two ends of the locking block 811 have inclined surfaces 8111. When the box 51 is in the locked state, the locking block 811 is inserted into the corresponding locking groove. When it is necessary to adjust the position of the box 51, the user applies a force to the box 51, which forces the box 51 to rotate relative to the groove 11. By providing inclined surfaces 8111 on both sides of the locking block 811 in the rotation direction of the rotating shaft 7, it is helpful to force the locking block 811 to exit from the corresponding locking groove when the user drives the box 51 to rotate relative to the groove 11.

[0088] Understandably, when the user forcefully drives the box body 51 to rotate relative to the groove 11, the rotating shaft 7 connected to the box body 51 will apply a resisting force to the locking block 811 through the side wall of the locking groove. This resisting force tends to force the locking block 811 out of the locking groove. By providing inclined surfaces 8111 on both sides of the locking block 811 along the rotation direction of the rotating shaft 7, the locking block 811 will be forced out of the corresponding locking groove under the guidance of the inclined surfaces 8111, thereby releasing the lock. The rotating shaft 7 is locked to allow the box 51 to rotate relative to the groove 11. During the rotation of the box 51, the elastic element 82 always applies a downward force to the locking rod 81, causing the locking block 811 to press against the outer periphery of the rotating shaft 7. When the box 51 rotates from the unfolded position to the retracted position, or from the retracted position to the unfolded position, the locking block 811 is re-inserted into the corresponding locking groove under the action of the elastic element 82, thereby realizing the re-locking and positioning of the box 51.

[0089] Furthermore, when the user drives the box 51 to rotate relative to the groove 11, in order to make the locking block 811 more easily disengage from the corresponding locking groove, the two side walls of the unfolded locking groove 71 and the retracted locking groove 72 along the rotation direction of the rotating shaft 7 can also be set as inclined surfaces. This, in conjunction with the inclined surface 8111 on the locking block 811, makes it easier to disengage the locking block 811 from the locking groove, thereby reducing the force required by the user to release the locking of the box 51.

[0090] In this embodiment, to ensure safety during use, specifically when the water dispensing component 5 is in the retracted position, to prevent accidental contact or operation of the water dispensing button on the control panel, thus avoiding unnecessary water discharge; in this embodiment, as... Figure 7As shown, a magnet 10 is installed on the side of the housing 51 near the notch 5121, and a Hall sensor is installed at a suitable position inside the housing 1. The Hall sensor, in conjunction with the magnet 10, is used to detect the position status of the water dispensing component 5, that is, to determine whether the water dispensing component 5 is in the retracted or extended position. The Hall sensor is communicatively connected to the control circuit board inside the housing 1. If the Hall sensor detects that the water dispensing component 5 is in the retracted position, the control circuit board locks the water dispensing button on the control panel, meaning that even if the button is pressed, the water dispensing process will not be triggered. When the Hall sensor detects that the water dispensing component 5 is in the extended position, the control circuit board unlocks the water dispensing button on the control panel, allowing the user to dispense water using the button.

[0091] Understandably, a linear Hall sensor is a sensor that can detect magnetic field strength and convert it into a voltage signal. Such a sensor typically contains a Hall element. When a magnetic field passes through the Hall element, a voltage difference is generated on both sides of the element. This voltage difference is proportional to the magnetic field strength. When the magnet 10 approaches or moves away from the linear Hall sensor, the magnetic field strength detected by the sensor changes. By measuring this change, the position of the magnet 10 (i.e., the box 51) can be determined.
