[0002] A water purifier is a water treatment device that can deeply filter and purify water. It can improve water quality and remove impurities, odors, heavy metals and harmful substances from the water to produce safe and clean drinking water or industrial water, according to people's requirements for water use.
[0003] As people's living standards improve, some water purifiers have added cooling functions to meet consumers' demand for cold drinking water. However, in daily use, there may be situations where the time interval between two uses (such as drinking) of cold water is relatively long, meaning the cold water has been left to stand for too long. In such cases, bacteria may be present in the water, which is detrimental to the health of the drinker. Utility Model Content

[0016] In one embodiment, the atomizing device includes any one of an ultrasonic atomizer, a piezoelectric atomizing plate, a magnetostrictive vibration atomizer, and a surface acoustic wave atomizer.
[0017] In one embodiment, the water treatment device further includes a water supply path, which is used to connect a water source and the filter assembly or to connect a water source and the input end of the cooling pipeline.

[0025] Alternatively, the cold water tank may have a drain outlet, one end of the water supply path may be connected to the drain outlet, and the other end of the water supply path may be connected to the cooling pipe and the cold water path.
[0026] According to the water treatment device of the above embodiment, by setting a water supply line connecting the cold water tank and the cooling pipeline, cold water in the cold water tank can be transported to the cooling pipeline.

[0042] Currently, some water treatment devices have added cooling functions to provide users with cold water. However, in daily use, cold water may be left to stand for too long, which could lead to the presence of bacteria in the water, posing a health risk to drinkers.
[0043] Therefore, this utility model provides a water treatment device that can avoid the long-term storage of prepared cold water.
[0044] Example 1:
[0045] like Figure 1 As shown, the water treatment device 100 provided in this embodiment of the present invention includes a filter assembly 10, which is used to filter the flowing water. By setting the filter assembly 10 to filter the flowing water, pure water can be generated, so that the water treatment device 100 can provide pure water.
[0046] Please see Figure 1 and Figure 2 The water treatment device 100 also includes a cold water tank 20, a temperature control device 30, a cooling pipe 40, and a water supply pipe 51. The cold water tank 20 is connected downstream of the filter assembly 10, and the pure water filtered by the filter assembly 10 flows into the cold water tank 20. The temperature control device 30 includes a temperature control body 31, a cooling component 32 connected to the cold end of the temperature control body 31, and a heat dissipation component 33 connected to the hot end of the temperature control body 31. The cooling component 32 is connected to the cold water tank 20 and is used to cool the water in the cold water tank 20, i.e., to cool the pure water in the cold water tank 20. The cooling pipe 40 is connected to the heat dissipation component 33 and is used to dissipate heat from the heat dissipation component 33, which is beneficial for the temperature control device 30 to regulate the water temperature. The cooling pipe 40 is located downstream of the cold water tank 20, and the water supply pipe 51 is connected between the cold water tank 20 and the input end of the cooling pipe 40. That is, the cold water in the cold water tank 20 can flow into the cooling pipe 40 through the water supply pipe 51. In specific applications, the pure water generated by the filter assembly 10 can flow into the cold water tank 20, and after being conditioned by the temperature regulating device 30 to generate cold water, it can flow into the cooling pipe 40 through the water supply pipe 51.
[0047] By adopting the above technical solution, a water supply path 51 is set between the cold water tank 20 and the cooling pipeline 40, allowing cold water in the cold water tank 20 to be transported to the cooling pipeline 40. This ensures that even if the user does not use the cold water for an extended period, the cold water in the cold water tank 20 can still be transported to the cooling pipeline 40 via the water supply path 51, preventing the prepared cold water from being stored in the cold water tank 20 for a long time. Furthermore, because the cold water is at a low temperature, transporting it to the cooling pipeline 40 to dissipate heat from the heat dissipation component 33 improves the heat dissipation efficiency of the cooling pipeline 40. Therefore, the water treatment device 100 provided in this embodiment prevents cold water from being stored in the cold water tank 20 for an extended period while effectively utilizing the cold water in the cold water tank 20, thus improving the heat dissipation effect on the heat dissipation component 33.
[0048] Please see Figure 1 and Figure 2 The cold water tank 20 includes a first tank 21 and a second tank 22 connected to each other. A cooling component 32 is connected to the first tank 21 to cool the water inside the first tank 21. The second tank 22 is used to store cold water. A filter assembly 10 is connected to the first tank 21, and a water supply path 51 is connected to the second tank 22. In specific applications, the pure water filtered by the filter assembly 10 is delivered to the first tank 21. The pure water in the first tank 21 is cooled by the cooling component 32 to generate cold water, which flows into and is stored in the second tank 22. The water supply path 51 connects the second tank 22 and the cooling pipe 40, delivering the cold water in the second tank 22 to the cooling pipe 40. This avoids storing cold water in the second tank 22 for extended periods, ensuring that the cold water in the second tank 22 is "fresh" filtered pure water.
[0049] Please see Figure 1 The water treatment device 100 also includes a cold water path 52, which is connected downstream of the cold water tank 20. The cold water tank 20 may be selectively connected to the cooling pipe 40 and / or to the cold water path 52. The cold water path 52 is used to transport cold water to the outside of the water treatment device 100 to provide cold water to users.
[0050] In practical applications, the cold water circuit 52 is connected to the second housing 22, and the second housing 22 can be selectively connected to the cooling pipe 40 and / or to the cold water circuit 52. When the second housing 22 is connected to the cooling pipe 40, the cold water in the second housing 22 can be transported to the cooling pipe 40 so that the cold water can be used to dissipate heat from the heat dissipation component 33; when the second housing 22 is connected to the cold water circuit 52, the cold water in the second housing 22 can be transported to the outside of the water treatment device 100 for user use.
[0051] In one embodiment, please refer to Figure 1 The cold water tank 20 has two drain outlets 23. A water supply line 51 is connected to one of the two drain outlets 23, and a cold water line 52 is connected to the other drain outlet 23. That is, the second tank 22 has two drain outlets 23, one connected to the water supply line 51 and the other connected to the cold water line 52. In another embodiment, please refer to... Figure 3 The cold water tank 20 can also be provided with a drain outlet 23. One end of the water supply line 51 is connected to the drain outlet 23, and the other end of the water supply line 51 is connected to the cooling pipe 40 and the cold water line 52.
[0052] In one embodiment, the output end of the cooling pipe 40 is connected to the inlet of the filter assembly 10, so that the water treatment device 100 has an internal circulation pipe. The internal circulation pipe includes the filter assembly 10, the cold water tank 20, the water supply path 51, and the cooling pipe 40. In specific applications, the cold water in the cold water tank 20 is transported to the cooling pipe 40 to dissipate heat from the heat dissipation component 33. After the water in the cooling pipe 40 dissipates heat, it is transported to the filter assembly 10, filtered again by the filter assembly 10, and then returned to the cold water tank 20. In this way, whether the water treatment device 100 is in the water discharge state or the water discharge state is stopped, it can dissipate heat from the heat dissipation component 33 through the cooling pipe 40, and the cold water in the cold water tank 20 is "fresh" filtered pure water, which can prevent the cold water from being stored in the cold water tank 20 for a long time.
[0053] Please see Figure 1 , Figure 2 and Figure 4 The water treatment device 100 also includes an atomizing device 60, which is located inside the cooling pipe 40 and close to its output end. In specific applications, cold water flows into the cooling pipe 40 from its input end, passes through the heat dissipation component 33, and dissipates heat to generate hot water, which then flows to the output end of the cooling pipe 40. By placing the atomizing device 60 close to the output end of the cooling pipe 40, the atomizing device 60 can atomize and cool the flowing hot water, thereby preventing the water temperature from becoming too high when it flows into the filter assembly 10.
[0054] In one embodiment, the heat sink is provided with a water guiding channel (not shown). The cooling pipe 40 includes a first cooling pipe section 41 and a second cooling pipe section 42. One end of the first cooling pipe section 41 is connected to the inlet of the water guiding channel, and the other end of the first cooling pipe section 41 forms the input end of the cooling pipe 40. One end of the second cooling pipe section 42 is connected to the outlet of the water guiding channel, and the other end of the second cooling pipe section 42 forms the output end of the cooling pipe 40. An atomizing device 60 is disposed in the second cooling pipe section 42. It can be understood that in other embodiments, the cooling pipe 40 may also be a single integral pipe that passes through the heat sink 33.
[0055] In one embodiment, the atomizing device 60 includes any one of an ultrasonic atomizer, a piezoelectric atomizing plate, a magnetostrictive vibration atomizer, and a surface acoustic wave atomizer.
[0056] Please see Figure 1 The water treatment device 100 also includes a water supply path 53, which connects a water source and a filter assembly 10. By providing the water supply path 53, the water source supplies water to the water treatment device 100. It will be understood that in other embodiments, please refer to... Figure 5 The water supply line 53 can also be used to connect the water source and the input end of the cooling pipe 40.
[0057] Please see Figure 1 The water treatment device 100 also includes a pure water path 54, which is connected to the pure water port of the filter assembly 10 and is used to transport the pure water generated by the filter assembly 10 to the outside of the water treatment device 100 for user use.
[0058] In one embodiment, the water treatment device 100 further includes a water supply path 55, which is connected between the pure water path 54 and the first housing 21. This allows the pure water produced by the filter assembly 10 to be delivered into the first housing 21.
[0059] The working principle of the water treatment device 100 provided in this embodiment is as follows:
[0060] 1) When the cold water tank 20 is connected to the cold water passage 52, the cold water in the cold water tank 20 can be transported to the cold water passage 52, and then to the outside of the water treatment device 100 for user use; wherein, when the cold water tank 20 is connected to the cold water passage 52, the cold water tank 20 can be connected to or disconnected from the cooling pipe 40;
[0061] 2) When the cold water tank 20 is disconnected from the cold water circuit 52, the cold water tank 20 is connected to the cooling pipe 40. The cold water in the cold water tank 20 is transported to the filter assembly 10 through the cooling pipe 40, and after being filtered by the filter assembly 10, it is transported back to the cold water tank 20.
[0062] Example 2:
[0063] Please see Figure 1 and Figure 6 The main difference between this embodiment and the water treatment device 100 provided in Embodiment 1 is that the connection components at the output end of the cooling pipe 40 are different. Specifically, in Embodiment 1, the output end of the cooling pipe 40 is connected to the inlet of the filter assembly 10; while in this embodiment, the output end of the cooling pipe 40 is connected to the pure water path 54.
[0064] It should be noted that in this embodiment, the water supply path 53 is connected to the filter assembly 10 and is used to supply water to the filter assembly 10.
[0065] By connecting the output end of the cooling pipe 40 to the pure water circuit 54, the cold water in the cold water tank 20 can be transported to the pure water circuit 54 via the cooling pipe 40, and then transported to the outside of the water treatment device 100 via the pure water circuit 54. This avoids the long-term storage of cold water in the cold water tank 20, and the water treatment device 100 can provide hot pure water. In practical applications, when room temperature pure water is required, the cold water tank 20 can be disconnected from the cooling pipe 40.
[0066] The working principle of the water treatment device 100 provided in this embodiment is as follows:
[0067] 1) When the cold water tank 20 is connected to the cold water passage 52, the cold water in the cold water tank 20 can be transported to the cold water passage 52, and then to the outside of the water treatment device 100 for user use; wherein, when the cold water tank 20 is connected to the cold water passage 52, the cold water tank 20 can be connected to or disconnected from the cooling pipe 40;
[0068] 2) When the cold water tank 20 is disconnected from the cold water circuit 52, the cold water tank 20 is connected to the cooling pipe 40. The cold water in the cold water tank 20 is transported to the pure water circuit 54 through the cooling pipe 40, and then transported to the outside of the water treatment device 100 through the pure water circuit 54.
[0069] Apart from the differences mentioned above, the water treatment device 100 and its components provided in this embodiment can be designed with reference to Embodiment 1, and will not be described further here.

Specifically, in Embodiment 1, the output end of the cooling pipe 40 is connected to the inlet of the filter assembly 10; while in this embodiment, the output end of the cooling pipe 40 is connected to the wastewater path 56.
[0072] Please see Figure 7 The water treatment device 100 also includes a wastewater path 56, which is connected to the filter assembly 10 and is used to transport the wastewater generated by the filter assembly 10. The output end of the cooling pipeline 40 is connected to the wastewater path 56.
[0073] It should be noted that in this embodiment, the water supply path 53 is connected to the filter assembly 10 and is used to supply water to the filter assembly 10.
[0074] By connecting the output end of the cooling pipe 40 to the wastewater pipe 56, the cold water in the cold water tank 20 can be transported to the wastewater pipe 56 via the cooling pipe 40, and then transported to the outside of the water treatment device 100 via the wastewater pipe 56. In this way, the cold water can be avoided from being stored in the cold water tank 20 for a long time.
[0075] The working principle of the water treatment device 100 provided in this embodiment is as follows:
[0076] 1) When the cold water tank 20 is connected to the cold water passage 52, the cold water in the cold water tank 20 can be transported to the cold water passage 52, and then to the outside of the water treatment device 100 for user use; wherein, when the cold water tank 20 is connected to the cold water passage 52, the cold water tank 20 can be connected to or disconnected from the cooling pipe 40;
[0077] 2) When the cold water tank 20 is disconnected from the cold water circuit 52, the cold water tank 20 is connected to the cooling pipe 40. The cold water in the cold water tank 20 is transported to the wastewater circuit 56 through the cooling pipe 40, and then transported to the outside of the water treatment device 100 through the wastewater circuit 56.
