Detailed Implementation

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the content of the embodiments. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0033] Example 1: As Figures 1-7 As shown, an instant hot water dispenser includes a dispenser body 1 and a water system disposed within the dispenser body 1, and a frame 2 for embedding and installation in a pre-set installation hole in the wall. The dispenser body 1 includes a panel 3 and a housing 4. The panel 3 is connected to the front end of the housing 4 and has an outlet connected to the water system. The bottom of the housing 4 has an inlet connected to the water system. The frame 2 has a receiving space 5, and at least one wire groove 6 connected to the receiving space 5 is provided on the frame 2. Multiple elastic locking mechanisms 7 are provided between the frame 2 and the housing 4. The elastic locking mechanisms 7 are used to automatically lock the housing 4 when the housing 4 is pushed into the receiving space 5 to a predetermined position, and allow the housing 4 to exit the receiving space 5 when a disassembly force is applied.

[0034] Example 2: Figures 1-7 As shown, unlike Embodiment 1, the water system includes,

[0035] Water inlet connector 8 is located at the bottom of housing 4 and forms a water inlet for connecting to an external water source;

[0036] Solenoid valve 9, the inlet end of solenoid valve 9 is connected to inlet connector 8, and is used to control the flow of water.

[0037] Water tank 10, the water inlet of water tank 10 is connected to the water outlet of solenoid valve 9, for water storage and pressure stabilization;

[0038] The instant heating module 11 is connected with the water outlet end of the water tank 10 for instant heating of water;

[0039] The water outlet joint 12 is connected with the water outlet end of the instant heating module 11 and extends to the panel 3 to form a water outlet.

[0040] In the above structure, the functional modules of the waterway system are arranged in sequence according to the water flow direction to realize the whole process control from water inlet to water outlet. The water inlet joint 8 is arranged at the bottom of the shell 4, which not only forms a physical interface of the water inlet, but also bears the standardized connection function with the external water source pipeline. The bottom is provided with a water inlet pipe for easy docking with the water inlet pipe passing through the wire slot 6 of the frame 2. The electromagnetic valve 9 is directly connected to the rear end of the water inlet joint 8, and the on-off of the water flow is controlled by the electric control mode, which not only ensures the safety of water use, but also realizes intelligent control. The water tank 10 is arranged after the electromagnetic valve 9, which not only stores a certain amount of clean water to meet the instantaneous large flow demand, but also plays a pressure stabilizing function, effectively alleviating the impact of municipal water pressure fluctuation on the subsequent heating module, and still providing short-term emergency water supply when the water is stopped.

[0041] The instant heating module 11 is the core of the whole system. The cold water flows into the water tank 10 and is heated to the set temperature in a very short time. This instant heating design completely avoids the problem of traditional storage water heater, ensures that each time the water is fresh and heated, and greatly improves the quality of drinking water. The water outlet joint 12 extends from the water outlet end of the instant heating module 11 to the position of the panel 3, and forms a visible water outlet on the panel 3. This integrated design not only ensures the sealing of the waterway, but also makes the water outlet position meet the ergonomic requirements.

[0042] The whole waterway system is integrated by modular series connection, which integrates water inlet control, buffer storage, instant heating and fixed point water outlet functions, and is convenient for fault diagnosis and module replacement.

[0043] In this embodiment, the bottom of the shell 4 is also provided with a drain 13, and a three-way piece 14 is installed in the shell 4. The first end of the three-way piece 14 is connected with the water outlet end of the water tank 10, the second end of the three-way piece 14 is connected with the water inlet end of the instant heating module 11, the third end of the three-way piece 14 is connected to the drain 13 through a drain pipeline 15, and a detachable plug 16 is installed at the drain 13.

[0044] In the above structure, the tee joint 14 is installed between the water outlet end of the water tank 10 and the water inlet end of the instant heating module 11, forming a water flow distribution node, with its first end receiving water from the water tank 10, its second end connecting the water inlet end of the instant heating module 11 to form the main water supply path, and its third end connecting to the drain port 13 at the bottom of the shell 4 through the drain pipeline 15. In the normal use state, the plug 16 closes the drain port 13, and the water flows from the water tank 10 through the first end and the second end of the tee joint 14 to the instant heating module 11, and the third end is in a closed state and does not affect normal water supply.

[0045] When the whole machine needs to be disassembled and repaired or is long-term idle, the plug 16 of the drain port 13 is removed, and the stored water in the system can be drained through the third end of the tee joint 14 and the drain pipeline 15. The main function of this design is to empty the waterway system before disassembling the whole machine, avoiding water overflow during disassembly, and preventing water quality deterioration during long-term idle. The drain port 13 is arranged at the bottom of the shell 4, and the gravity is used to make the drainage more thorough.

[0046] The arrangement of the tee joint 14 makes the drain function relatively independent of the main waterway, and the system can be emptied without disassembling the pipeline connection. The design of the detachable plug 16 simplifies the operation process, and the user can conveniently open or close the drain port 13 when needed.

[0047] In this embodiment, the upper end of the shell 4 is provided with a plurality of mounting holes 17, each elastic locking mechanism 7 includes a plurality of press-in nuts 18 arranged at the upper end of the frame 2 and an elastic pin assembly 19 installed in the press-in nut 18, each elastic pin assembly 19 includes a pin body 20, a spring 21 and a fixed tube 22, the fixed tube 22 is connected with the press-in nut 18, the pin body 20 is telescopically arranged in the fixed tube 22, and the spring 21 is arranged in the fixed tube 22 and acts on the pin body 20, so that the pin body 20 has a tendency to protrude into the corresponding mounting hole 17.

[0048] In the above structure, the press-in nut 18 is fixedly installed at the upper end of the frame 2, providing a stable installation basis for the entire locking mechanism. The elastic pin assembly 19 serves as a locking execution unit and is connected with the press-in nut 18 through the fixed tube 22, forming a reliable assembly relationship. The pin body 20 can move up and down in the fixed tube 22, and the spring 21 continuously acts on the pin body 20, so that the pin body 20 always has a tendency to protrude downward. This preloading design ensures the reliable triggering of the locking action.

[0049] The plurality of mounting holes 17 on the upper end of the shell 4 correspond to the positions of the elastic pin assembly 19, forming a locking fit. During installation, when the shell 4 is pushed into the frame 2, the pin body 20 first contacts the surface of the shell 4 and is compressed into the fixing tube 22, and the spring 21 is compressed to store potential energy; when the shell 4 continues to be pushed in, the mounting hole 17 moves to a position aligned with the pin body 20, the compressed spring 21 releases energy, pushing the pin body 20 to quickly pop out and insert into the mounting hole 17, completing the locking action. This design simplifies the complex alignment and locking process into a single push-in action, eliminating the need for precise alignment or the use of tools.

[0050] The distributed arrangement of the plurality of elastic locking mechanisms 7 also forms a multi-point support system, with each locking point working independently and in cooperation with each other to ensure the stability of the connection and the uniformity of the load bearing. The guiding and restraining of the pin body 20 by the fixing tube 22 ensures the accuracy of its movement, avoiding deflection or jamming. When disassembly is required, the shell 4 is pulled outward, and the edges of the mounting hole 17 exert an oblique force on the pin, forcing it to compress the spring 21 and retract into the fixing tube 22, thereby releasing the lock. The entire process is relatively convenient to operate.

[0051] Embodiment Three: As shown in Figures 1-7 Unlike Embodiment Two, the upper end of the shell 4 is provided with a plurality of guide grooves 23 extending in the push-in direction of the pipeline machine body 1. The guide groove 23 includes a groove bottom wall and two side groove walls, and the mounting hole 17 is arranged on the groove bottom wall. The two side groove walls and the groove bottom wall form a limiting space 24 that accommodates the pin body 20.

[0052] In the above structure, the guide groove 23 is arranged at the upper end of the shell 4 and extends in the push-in direction of the pipeline machine, providing a continuous movement trajectory for the pin body 20. The groove bottom wall serves as the main bearing surface, with its surface directly contacting the pin body 20 to guide the sliding path of the pin during the push-in process. The mounting hole 17 is opened on the groove bottom wall, and when the pin body 20 slides to this position, it can accurately fall into and complete the locking. The two side groove walls extend upward perpendicular to the groove bottom wall, together with the groove bottom wall to form a U-shaped limiting space 24.

[0053] During installation, the guide groove 23 plays a key guiding role. When the shell 4 begins to be pushed in, the pin body 20 enters the guide groove 23, and the groove bottom wall guides it to slide along the predetermined path, avoiding deviation or misalignment. The pin body 20 always maintains contact pressure with the groove bottom wall under the action of the spring 21, ensuring a stable sliding state. When the pin body 20 reaches the position of the mounting hole 17, the spring 21 thrust makes it immediately pop into the hole, achieving precise locking.

[0054] The design of the limiting space 24 enhances the stability after locking. After the pin body 20 is inserted into the mounting hole 17, the upper end thereof is still located in the limiting space 24 formed by the groove side wall. The groove side wall transversely restricts the pin, preventing the pipeline machine from shifting left and right or rotating during use. The groove bottom wall provides vertical support. This three-dimensional constraint structure enables each locking point to have good anti-deviation capability.

[0055] In this embodiment, the groove bottom wall includes, in sequence along the pushing direction of the pipeline machine body 1, an inclined section 25, a transition section 26, and a smooth section 27. The inclined section 25 is arranged downward from front to back. The smooth section 27 is flush with the outer surface of the shell 4. The transition section 26 connects the inclined section 25 and the smooth section 27. The mounting hole 17 is arranged on the smooth section 27.

[0056] The inclined section 25 is located at the front end entrance of the guide groove 23 and is designed as a downward slope from front to back. When the shell 4 starts to be pushed in, the pin body 20 first contacts the inclined section 25. The slope converts the horizontal pushing force into a vertical downward component, causing the pin body 20 to gradually compress into the fixed tube 22. This slope guidance avoids hard collision between the pin body 20 and the shell 4, reduces the pushing resistance, and makes the installation process more labor-saving.

[0057] The transition section 26 connects the inclined section 25 and the smooth section 27 and forms a gentle curved transition. This design ensures smooth and continuous conversion of the pin body 20 from the compressed state to the sliding state, avoiding sudden resistance or jamming at the profile transition. The curvature design of the transition section 26 enables the pin to smoothly complete the transition of the motion state and maintain stable contact pressure.

[0058] The smooth section 27 is flush with the outer surface of the shell 4, providing a stable sliding plane for the pin body 20. The pin body 20 maintains constant contact pressure with the smooth section 27 under the action of the spring 21 and slides along the smooth section 27 until it reaches the mounting hole 17. The flat design of the smooth section 27 ensures the stability and consistency of the motion of the pin body 20 and does not produce additional compression or release. The mounting hole 17 is arranged on the smooth section 27. At this time, the pin body 20 has completed the compression process of the inclined section 25 and is in a stable pre-compressed state. When the hole position is aligned, the potential energy stored by the spring 21 is released instantaneously, pushing the pin body 20 to quickly and accurately pop into the hole.

[0059] In this embodiment, the upper part of the panel 3 is provided with a display light box 28. The front surface of the display light box 28 is provided with a display screen. The water outlet is located at the lower end central position of the display light box 28. The lower part of the panel 3 is provided with a water collecting tray 29, which is arranged horizontally forward and is used to collect water droplets dripping from the water outlet.

[0060] The functional layout of the whole panel 3 is from top to bottom in turn as display area, water outlet area and receiving area, forming clear functional stratification. This vertical layout conforms to the user's usage habits, observing information at the upper part, water outlet at the middle part, and protection at the lower part, the functional areas do not interfere with each other and cooperate with each other, improving the convenience and safety of the product.

[0061] Specifically, the display lamp box 28 is arranged at the upper part of the panel 3, which is convenient for the user to observe the working state, and the display screen is installed on the front of the display lamp box 28, which can display the working parameters such as water temperature and water volume in real time, providing intuitive operation feedback for the user. The box structure of the display lamp box 28 not only protects the internal electronic display components, but also forms a certain shielding effect through appropriate protruding design, reducing the influence of water vapor on the display screen.

[0062] The water outlet is located at the lower end of the display lamp box 28, thereby ensuring the symmetry and stability of the water outlet. The user can easily align the water cup or container with the water outlet. The water outlet is arranged below the display lamp box 28, which utilizes the protruding structure of the lamp box to form a natural avoiding space, facilitating the placement of containers of different heights. At the same time, this top-down layout enables the user to observe the information on the display screen while receiving water, achieving the continuity of operation.

[0063] The water receiving tray 29 is arranged at the lower part of the panel 3 and extends horizontally forward, forming effective splash protection. Its main function is to receive the water droplets that may fall from the water outlet, preventing water droplets from falling to the ground or countertop and causing pollution. The forward extension design expands the water receiving range. Even if the user's container position deviates slightly during water receiving, the falling water droplets can still be received by the water receiving tray 29. The horizontal extension of the water receiving tray 29 can also serve as a temporary cup placement platform, allowing the user to place the water cup on it for water receiving operation.

[0064] In this embodiment, the rear end of the shell 4 is also provided with a cable storage slot 30 and a socket mounting position 31 which are in communication with each other. A plurality of limiting protrusions 32 are arranged in the cable storage slot 30, and a winding space is formed between the plurality of limiting protrusions 32. The socket mounting position 31 is provided with a socket for inserting the power supply plug.

[0065] In the above structure, the cable storage slot 30 provides a special cable winding space, solving the common problem of mismatch between the length of the power cord and the actual demand. In actual installation, the reserved power cord is often longer than the actual required length. If the excess cable is not managed, it will form a messy accumulation inside the frame 2, which not only affects the appearance, but also may interfere with other components. The plurality of limiting protrusions 32 in the cable storage slot 30 form a guiding structure for cable winding. The user can orderly wind the excess power cord between the limiting protrusions 32 to form a regular coil. According to the actual length of the cable, the number of coils and the path can be selected to achieve flexible length adjustment.

[0066] The socket arranged in the socket mounting position 31 is designed in a recessed manner, forming a protective containing space 5. When the power plug is inserted into the socket, the entire plug is located in the recess of the socket mounting position 31 and does not protrude from the surface of the shell 4. This built-in design avoids the problems caused by the exposed plug, preventing the plug from colliding with the inner wall of the frame 2 during installation and avoiding the safety hazards of dust accumulation or accidental touch of the exposed plug.

[0067] In this embodiment, at least two press-in pins 33 are fixedly arranged at the lower end of the frame 2, and the press-in pins 33 extend vertically upward. The bottom of the shell 4 is provided with positioning holes 34 corresponding to the press-in pins 33.

[0068] In the above structure, the press-in pins 33 are fixedly arranged at the lower end of the frame 2 and arranged in a vertically upward manner, providing an accurate positioning reference for the installation of the pipeline machine. The arrangement of at least two pins ensures the stability of the positioning and avoids the rotation or deflection that may be caused by single-point positioning.

[0069] The positioning holes 34 at the corresponding positions of the bottom of the shell 4 form a cooperation relationship with the press-in pins 33. During installation, the user first tilts the shell 4 at a certain angle, so that the bottom positioning holes 34 are aligned and fitted into the press-in pins 33. At this time, the press-in pins 33 bear the main weight of the pipeline machine, forming a stable support point, so that the installer does not need to lift the entire pipeline machine, reducing the installation intensity.

[0070] This structure of lower support and upper locking fully utilizes the principle of gravity and leverage. With the bottom press-in pins 33 as the fulcrum, the pipeline machine can be easily rotated upward and righted. During the righting process, the upper elastic locking mechanism 7 gradually comes into contact with the shell 4 and completes automatic locking. The entire installation process forms a clear operation sequence: first positioning the lower part, then locking the upper part, avoiding the difficulty of aligning multiple positions at the same time.

[0071] The cooperation of the press-in pins 33 and the positioning holes 34 also plays a role in preventing incorrect installation. The position and spacing of the pins are accurately designed to ensure that the pipeline machine can only be installed in the correct direction and position, avoiding the possibility of reverse or misaligned installation. After the pipeline machine is completely installed, the bottom press-in pins 33 continue to provide vertical support, together with the upper elastic locking mechanism 7, forming a stable fixing system that effectively shares the weight of the pipeline machine, improving the reliability of long-term use.

[0072] In this embodiment, a plurality of strip-shaped grooves 35 are arranged on the frame 2 for the self-tapping screws to pass through.

[0073] In the above structure, the strip-shaped slot 35 adopts a long strip-shaped opening design, which has obvious adjustment advantages compared with the traditional circular fixing hole. The self-tapping screw can be fixed to the wall body at a suitable position within the length range of the slot. This design effectively solves the actual problems of size deviation of the wall installation hole and fine adjustment of the positioning of the frame 2.

[0074] In actual installation, there is a certain size error or position deviation in the wall hole. The design of the strip-shaped slot 35 allows the installer to adjust the screw position in the slot according to the actual situation, ensuring that the frame 2 can be accurately aligned and installed horizontally. This flexibility avoids forced alignment caused by fixed fixing hole position, reduces installation stress and potential structural damage.

[0075] The above description is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
