DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the contents in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0027] Embodiment one: as Figures 1-6As shown, a wall-mounted pipeline machine suitable for children includes a machine body 1 and a main control board 2 arranged in the machine body 1. The machine body 1 is further provided with an electromagnetic valve 3, a water tank 4 and an instant heating module 5 connected in sequence. The electromagnetic valve 3 is connected with a water inlet 6, and the instant heating module 5 is connected with a water outlet 7. The main control board 2 is electrically connected with the electromagnetic valve 3 and the instant heating module 5, respectively, for controlling the opening and closing of the electromagnetic valve 3 and the heating temperature of the instant heating module 5. The front side of the machine body 1 is provided with a control panel 8, which is provided with a plurality of temperature selection buttons electrically connected to the main control board 2. The main control board 2 is used to control the heating temperature of the instant heating module 5 and the opening and closing of the electromagnetic valve 3 according to the operation of the temperature selection buttons. The lower part of the side wall of the machine body 1 is provided with a child button 9 electrically connected to the main control board 2. The child button 9 is configured to cooperate with the main control board 2 to control the electromagnetic valve 3 to open and output a preset low-temperature water to the water outlet 7 through the instant heating module 5 when the main control board 2 receives a signal from the child button 9.

[0028] Embodiment two: as Figures 1-6 shown, different from embodiment one, the temperature range of the preset low-temperature water is 40-50℃, and the water output range is 50-100ml.

[0029] In the above structure, the temperature range of the preset low-temperature water is 40-50℃, and the water output range is 50-100ml. The setting of this temperature range is based on the physiological characteristics of children and safety considerations. Warm water with a temperature of 40-50℃ is close to the body temperature of human beings, and children can directly drink it without causing gastrointestinal discomfort due to too low water temperature. At the same time, this temperature is far below the temperature threshold that can cause scalding (usually above 60℃ will have the risk of scalding), so even if the child accidentally spills water on the skin during operation, it will not cause harm. The water volume of 50-100ml is fully considered the drinking habits and physiological needs of children. This capacity can not only meet the basic needs of children's single drinking, but also will not cause waste due to too much water that children cannot finish drinking at one time. At the same time, the small amount of water output also reduces the risk of water splashing or cup overflow when children operate.

[0030] In this embodiment, the child button 9 includes a button cap 10, a reset spring 11, a button rod 12 and a micro switch 13. The button cap 10 is exposed outside the side wall of the machine body 1. One end of the button rod 12 is fixedly connected with the button cap 10, and the other end penetrates through the side wall of the machine body 1 and extends into the inside of the machine body 1. The reset spring 11 is sleeved on the button rod 12, and the two ends thereof abut against the button cap 10 and the micro switch 13, respectively. The micro switch 13 is fixed on a bracket 14, and the bracket 14 is fixed in the machine body 1. The contact of the micro switch 13 corresponds to the end of the button rod 12, and the micro switch 13 is electrically connected with the main control board 2 through a wire.

[0031] The aforementioned mechanical button structure offers excellent tactile feedback and reliability. When a child presses the button cap 10, the cap moves the button lever 12 inward, pressing the contact of the micro switch 13 to close. An electrical signal is transmitted to the main control board 2 via a wire, triggering the water dispensing program. Upon releasing the button cap 10, the return spring 11 pushes the cap and lever 12 back to their initial positions, disengaging the micro switch 13 contact and completing one button operation. The return spring 11 ensures automatic button reset, preventing button jamming and continuous water dispensing. The micro switch 13, as an electrical triggering element, features moderate triggering force, sensitive response, and long service life. Combined with the stable installation of the bracket 14, this ensures the stability and durability of the button operation. The entire button structure uses a mechanical triggering method, making it more suitable for children than touch-sensitive buttons. Children can judge the success of the operation through clear pressing actions and tactile feedback. Furthermore, the mechanical structure is less susceptible to interference from moisture, static electricity, and other environmental factors, maintaining stable operation even in humid environments such as kitchens.

[0032] Example 3: Figures 1-6 As shown, unlike Embodiment 2, in this embodiment, the control panel 8 includes a panel frame 15 and a display screen 16. Multiple temperature selection buttons include a room temperature button 17, a body temperature water button 18, a formula button 19, a honey button 20, a coffee button 21, and a tea button 22. These buttons are spaced apart on the panel frame 15. The display screen 16 is embedded in the upper part of the panel frame 15 and is used to display the current water temperature and water output. The control panel 8 also has a child lock button 23, which is electrically connected to the main control board 2 and is used to lock the temperature selection buttons with a temperature higher than 50°C.

[0033] The above temperature grading design fully considers the needs of different use scenarios. The normal temperature key 17 provides 25℃ normal temperature water suitable for daily direct drinking, the body temperature water key 18 outputs 36.5℃ body temperature water especially suitable for children and the elderly to drink, the milk key 19 is set to 45℃, which meets the best temperature requirement of infant milk powder, the honey key 20 provides 65℃ warm water suitable for mixing honey and other nutrients, the coffee key 21 outputs 85℃ hot water to meet the brewing requirement of instant coffee, and the tea key 22 provides 100℃ boiling water for tea brewing. The setting of the child lock key 23 realizes safe grading management. In the child lock locked state, the normal temperature key 17, the body temperature water key 18 and the milk key 19 can still be normally operated to ensure the basic drinking water requirement, while the honey key 20, the coffee key 21 and the tea key 22 are locked and cannot be used. When the user tries to operate these high-temperature keys, the system will issue a prompt sound and display a child lock icon flashing to remind that the user needs to unlock first. The real-time display function of the display screen 16 enables the user to intuitively understand the current water temperature and water quantity setting, avoiding operation errors. This design not only meets the diversified drinking water requirements of family members, but also realizes safe control of high-temperature water through the child lock function. Especially, 50℃ is taken as the safe temperature dividing line. The keys below this temperature can still be used in the child lock state, ensuring that the normal drinking water of children and other family members is not affected within the safe range.

[0034] In the embodiment, a water level sensor 24 is arranged in the water tank 4, and a temperature sensor 25 is arranged at the water outlet end of the heating module 5. The water level sensor 24 and the temperature sensor 25 are electrically connected with the main control board 2.

[0035] In the above structure, the water level sensor 24 monitors the water level state in the water tank 4 in real time. When it is detected that the water level is below the set threshold, a water shortage signal is sent to the main control board 2. The main control board 2 controls the system to stop heating and prompts a water shortage warning on the display screen 16, avoiding the risk of dry burning damage of the heating module 5. At the same time, the water level sensor 24 can also detect whether the water tank 4 is full during the water replenishment process, preventing water overflow and causing internal circuit short circuit of the machine. The temperature sensor 25 is arranged at the water outlet end of the heating module 5. This position can accurately detect the actual water temperature output to the user, rather than only monitoring the temperature of the heating module itself. The main control board 2 performs closed-loop control according to the real-time feedback data of the temperature sensor 25, dynamically adjusts the heating power of the heating module 5, and ensures that the water outlet temperature is consistent with the target temperature selected by the user. Especially in the water outlet process triggered by the child key 9, the temperature sensor 25 can monitor whether the water temperature is maintained within the safe range of 40-50℃. Once the temperature is detected to be abnormally high, the main control board 2 will immediately reduce the heating power or stop heating, providing protection for the safety of children drinking water.

[0036] Embodiment Four: as Figures 1-6As shown, unlike Example Three, the bottom of the body 1 is provided with a drain 26, and a tee joint 27 is installed in the body 1, the first end of the tee joint 27 is connected with the water outlet end of the water tank 4, the second end of the tee joint 27 is connected with the water inlet end of the instant heating module 5, and the third end of the tee joint 27 is connected to the drain 26 through a drain pipeline 28, and a detachable plug 29 is installed at the drain 26.

[0037] This tee joint structure design plays a key role in the waterway system, in the normal working state, the water flows from the water outlet end of the water tank 4 through the first end of the tee joint 27, and then flows to the instant heating module 5 through the second end for heating, and the third end is closed due to the plug 29, and is in a closed state. When cleaning and maintenance is needed, the user can remove the plug 29 of the drain 26, and the remaining water in the water tank 4 is drained from the bottom drain 26 through the third end of the tee joint 27 and the drain pipeline 28 under the action of gravity, realizing the emptying of the water tank 4 and the pipeline, avoiding the problem of water quality deterioration or bacteria breeding in the pipeline when not used for a long time. The detachable plug 29 design makes the drainage operation simple and easy, and the user can complete the drainage and sealing operation without professional tools, and the tee joint 27 is arranged between the water tank 4 and the instant heating module 5 to ensure the thoroughness of the drainage, which not only empties the water in the water tank 4, but also drains the residual water in the pipeline between the water tank 4 and the tee joint 27.

[0038] In this embodiment, the front side of the body 1 is provided with a detachable water receiving tray 30, which is located directly below the water outlet 7.

[0039] The water receiving tray 30 provides an important protection function for daily use. In the process of taking water, it is inevitable that water droplets will fall or a small amount of water will overflow when children operate. The water receiving tray 30 can effectively receive these falling water droplets, prevent water stains from polluting the table or the ground, and keep the use environment clean and dry. The detachable design makes the cleaning and maintenance of the water receiving tray 30 simple and convenient, and the user can regularly remove the water receiving tray 30 for cleaning, avoiding the problem of bacterial breeding or scale accumulation caused by long-term storage of accumulated water.

[0040] Example Five: As shown, Figures 1-7 Unlike Example Two, the child key 9 includes a key cap 10, an elastic arm 31 and a micro switch 13, the micro switch 13 is fixed in the body 1 through a support 14 and is electrically connected with the main control board 2 through wires, and the key cap 10 is connected on the side wall of the body 1 through the elastic arm 31 and contacts the contact of the micro switch 13 when stressed.

[0041] The elastic arm 31 and the key cap 10 are manufactured by an integral molding process, the overall structural rigidity and position accuracy are guaranteed, the cantilever mounting mode makes the key cap 10 stably keep the predetermined position in the natural state, and the controllable elastic deformation is generated when being pressed, the trigger point in the inner side of the key cap 10 corresponds to the contact of the micro switch 13, when the outer convex key cap 10 is pressed by the pressing force, the elastic arm 31 is bent and deformed, drives the key cap 10 to move inward, makes the trigger point contact and press the contact of the micro switch 13, completes the circuit closing and sends the trigger signal to the main control board 2; when the pressing force is released, the elastic arm 31 returns to the initial form by the elastic restoring force, drives the key cap 10 to separate from the contact of the micro switch 13 and reset to the original position, completes a complete key operation cycle.

[0042] The above only describes the embodiments of the present application, and does not limit the patent scope of the present application, any equivalent structure or equivalent flow transformation using the content of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
