[0037] The present disclosure is further illustrated below by way of embodiments, but the present disclosure is not limited to the scope of the embodiments described herein.

[0038] The prefixes such as "first" and "second" used in this disclosure are merely for distinguishing different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes used to distinguish descriptive objects in this disclosure does not constitute a limitation on the described objects.

[0039] Example 1

[0040] In this embodiment, the water outlet regulating structure of the water purification device is installed near the water outlet end of the water purification pipeline in the water purification device, such as... Figure 1 As shown; under normal circumstances, the purified water pipes carry room temperature water.

[0041] like Figure 2 As shown, the water outlet regulating structure includes an evaporation unit 1 and a refrigeration unit 2. The evaporation unit 1 includes a cold water pipe 3 and an evaporation component 4. Both ends of the cold water pipe 3 are connected to the water purification pipe in the water purification device. The evaporation component 4 is arranged around the cold water pipe 3 and is connected to the refrigeration circuit of the refrigeration unit 2.

[0042] The evaporation component 4 can be located inside or outside the cold water pipe 3, and is positioned close to the cold water pipe.

[0043] The evaporation component 4 is used to absorb the energy of the water flowing from the clean water pipe into the cold water pipe 3 and to cool and regulate the water flowing through the cold water pipe 3 so that cold water is discharged from the outlet of the clean water pipe.

[0044] In this solution, by optimizing the design of the outlet water regulating pipeline, the cold water pipeline 3, which is designed to work in conjunction with the evaporator 4, is directly connected to the purified water pipeline in the water purification device. This allows the heat from the room-temperature water in the purified water pipeline to be absorbed by the evaporator 4 when it flows through the cold water pipeline 3, thus significantly reducing the temperature of the flowing water. At the same time, this outlet water regulating structure is connected to the refrigeration circuit of the larger refrigeration unit 2, achieving efficient cooling of the small portion of water in the cold water pipeline 3. This enables the water purification device to provide cold water instantly and continuously, improving the user's water experience. It effectively avoids the problems of bacterial growth, energy consumption, and large volume that exist in solutions that use a cold tank for water cooling. Furthermore, this outlet water regulating structure also has the advantages of simple structure and small volume.

[0045] Example 2

[0046] The water outlet adjustment structure in the water purification device of this embodiment is a further improvement on Embodiment 1, specifically:

[0047] In a feasible solution, such as Figure 3 As shown, the evaporation component 4 includes a first evaporation tube 5, which is located inside the cold water pipe 3 and is arranged along the laying direction of the cold water pipe 3.

[0048] And / or,

[0049] The evaporation component 4 includes a second evaporation tube 6, which is sleeved on the outside of the cold water pipe 3 and arranged along the laying direction of the cold water pipe 3.

[0050] Preferably, such as Figure 4 As shown, the evaporation component 4 includes a first evaporation pipe 5 located inside the cold water pipe 3 and a second evaporation pipe 6 sleeved on the outside of the cold water pipe 3.

[0051] Both the first evaporator tube 5 and the second evaporator tube 6 are made of metal, which can be made of a single metal or multiple metals; in one embodiment, copper metal tubes can be used as the first evaporator tube 5 and the second evaporator tube 6.

[0052] In this solution, through clever pipeline design, namely, matching the layout of cold water pipeline 3 with the synchronous design of evaporation pipe, the water flowing through cold water pipeline 3 can quickly and efficiently absorb heat to ensure the cold water output requirement.

[0053] In a feasible solution, such as Figure 4 As shown, a first connection port 7 and a second connection port 8 are provided at both ends of the cold water pipe 3, and the first connection port 7 and the second connection port 8 are connected to the body of the cold water pipe 3.

[0054] The cold water pipe 3 is connected to the purified water pipe through two first connection ports 7 at both ends; the two first connection ports 7 correspond to the inlet and outlet of the cold water pipe 3, respectively. Temperature sensors are installed at both locations to detect the actual temperature value at the corresponding location and send it to the controller of the water purification device.

[0055] The cold water pipe 3 is connected to the refrigeration circuit through two second connection ports 8 at both ends.

[0056] In this solution, a matching connection part is provided at the connection point between the purified water pipe and the cold water pipe 3, so that the first connection port 7 can be fixed, stable, reliable and sealed with the purified water pipe, thereby ensuring stable water flow transmission; similarly, a structurally matching connection part is also provided at the connection point between the refrigeration circuit and the second connection port 8, so that the second connection port 8 can be fixed, stable and reliable and sealed with the refrigeration circuit, thereby ensuring efficient refrigeration.

[0057] Of course, depending on actual needs, the first connection port 7 can be integrally formed with the water purification pipe, and the second connection port 8 can be integrally formed with the specific structure in the refrigeration circuit.

[0058] In a feasible solution, such as Figure 4 As shown, the evaporation unit 1 also includes a pipe cover 9, which is used to cover the second connection ports 8 at both ends of the cold water pipe 3 to prevent water from flowing out of the cold water pipe 3 at the second connection ports 8.

[0059] In this solution, the water flow from the cold water pipe 3 is blocked by the pipe cover 9 to prevent water from entering the refrigeration circuit and to ensure the rationality of the structural design. The pipe cover 9 can be fixedly connected to the second connection port 8 at both ends of the cold water pipe 3 by means of a threaded structure, or it can be set at the second connection port 8 at both ends of the cold water pipe 3 by means of integral molding.

[0060] Specifically, when the evaporation component 4 includes a first evaporation tube 5, the tube cover 9 is used to cover the end face gap between the second connection port 8 and the first evaporation tube 5; wherein, the first evaporation tube 5 extends out of the tube cover 9;

[0061] When the evaporation component 4 includes the second evaporation tube 6, the tube cover 9 is used to cover the entire end face of the second connection port 8. At this time, only the second evaporation tube 6 is connected to the refrigeration circuit to achieve the refrigeration effect on the cold water pipe 3.

[0062] In a feasible solution, such as Figure 5 As shown, the water outlet regulating structure includes a spiral structure.

[0063] In this design, a spiral structure is used, which makes the path in the cold water pipe 3 longer within a certain space. This allows for a longer contact time between the water flow and the first evaporator 5 and the second evaporator 6 in the cold water pipe 3. This results in better absorption of heat from the water flow, leading to a more suitable cold water temperature and ensuring a better cold water output effect.

[0064] In a feasible solution, such as Figure 6 As shown, the refrigeration unit 2 includes a compressor 10, a condenser 11, and a capillary tube 12 arranged in sequence.

[0065] One end of the first evaporator tube 5 and / or the second evaporator tube 6 in the evaporation unit 1 is connected to the compressor, and the other end is connected to the capillary tube;

[0066] In this scheme, the refrigeration unit 2 is a large-volume refrigeration structure. The water outlet regulating structure is connected to the refrigeration circuit of the large refrigeration unit 2 to achieve efficient cooling of the small portion of water in the cold water pipe 3, so as to achieve the effect of the water purification device producing cold water immediately and continuously.

[0067] In one feasible embodiment, the evaporation unit 1 further includes an insulation layer fixed to the outside of the evaporation component 4.

[0068] In this solution, an insulation layer is installed on the outside of the evaporator 4 by wrapping or other means to further ensure the stability of the cold water output and achieve a better water output effect.

[0069] The structure and implementation principle of the water outlet adjustment structure in this embodiment are explained in detail below:

[0070] In this embodiment, the water outlet regulating structure includes a spiral cold water pipe 3, a first evaporator 5 arranged along the path of the cold water pipe 3 and located inside the cold water pipe 3, and a second evaporator 6 sleeved on the outside of the cold water pipe 3 and arranged along the path of the cold water pipe 3, that is, the first evaporator 5, the cold water pipe 3, and the second evaporator 6 are arranged sequentially from the inside to the outside; the cold water pipe 3 is connected to the purified water pipe through the first connection ports 7 at both ends to realize the transmission of the flowing water; the cold water pipe 3 is blocked by the pipe caps 9 at the second connection ports 8 at both ends to ensure that the water flows only in the cold water pipe 3 and cannot flow out of the cold water pipe 3; the first evaporator 5 and the second evaporator 6 are both connected to the refrigeration unit 2, specifically, one end of the first evaporator 5 and the second evaporator 6 are both connected to the compressor, and the other end is both connected to the capillary tube.

[0071] During the cooling water dispensing process, the controller drives the compressor to start cooling, thereby cooling the first evaporator 5 and the second evaporator 6. In this way, the first evaporator 5 and the second evaporator 6 absorb energy from the water flow in the cold water pipe 3, achieving the cooling treatment of the water flow passing through the spiral structure of the cold water pipe 3. That is, by connecting with the cooling circuit of the larger cooling unit 2, the efficient cooling of the water in the small section of the cold water pipe 3 is achieved, so that the water purification device can achieve the effect of dispensing cold water immediately and continuously, improving the user's water experience.

[0072] Example 3

[0073] like Figure 7 As shown, the water purification device in this embodiment includes the water outlet adjustment structure 100 of embodiment 1 or 2.

[0074] Specifically, the water purification device also includes a controller 200, a flow regulating valve 300 installed on the water purification pipeline, and a first temperature sensor 401 (temperature sensor for the inlet and outlet) and a second temperature sensor 402 (temperature sensor for the outlet) installed at both ends of the water outlet regulating structure. The flow regulating valve and the temperature sensor are both connected to the controller in communication.

[0075] The controller is used to receive temperature data collected by the temperature sensor and drive the operation of the flow regulating valve so that the temperature of the water flowing out of the water outlet of the water purification device reaches the preset cold water outlet temperature range.

[0076] In this solution, the controller automatically drives the flow regulating valve on the water purification pipeline to change the water flow rate in the cold water pipeline passing through the outlet regulating structure, thereby changing the temperature of the water flowing out of the outlet of the water purification pipeline and achieving the effect of adjustable water temperature and instant cold water output.

[0077] It should be noted that the focus of this solution is to protect the structural improvements of the water purification device. The implementation principle of the controller designed for this device is a function that already exists in the existing controller and is not within the scope of protection of this solution.

[0078] In one feasible solution, the compressor in the outlet water regulating structure includes a variable frequency compressor; wherein the operating power of the variable frequency compressor is matched with the outlet water temperature requirement.

[0079] In this solution, the compressor's operating frequency is adjustable. Based on the drive commands sent by the controller, the compressor is adjusted to the corresponding operating frequency to provide the corresponding cooling effect to the evaporator component, thereby ensuring that the water output reaches the corresponding cold water temperature range and further improving the user's water experience.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this disclosure, but all such changes and modifications fall within the scope of protection of this disclosure.
