Abstract
Description
Technical Field
[0001] This utility model relates to the field of direct drinking water machine technology, and in particular to a true boiling water outlet. Background Technology
[0002] Existing water purifiers generally have a heating function. However, because boiling water produces a large amount of steam, if not controlled, the steam mixes with the boiling water and sprays out, resulting in inconsistent and scalding water flow. Although some water purifiers are equipped with steam-water separation structures at the spout, these structures cannot effectively separate the steam from the water when the water is truly boiling, leading to inconsistent water flow. To reduce steam volume and alleviate the pressure on steam-water separation, current water purifiers typically control the hot water temperature within a certain range from the boiling point, meaning the water is not truly boiling. However, while this alleviates the steam-water separation problem to some extent, it also prevents users from obtaining truly boiling water, affecting the quality and taste of the drinking water. Utility Model Content

[0018] The true boiling water outlet provided in this application has at least the following advantages over the prior art:
[0019] This true boiling water outlet features a multi-stage steam exhaust structure created by incorporating a first and second exhaust pipe within the water-vapor separation chamber. When faced with the large amount of steam generated during true boiling, the steam can be discharged through both the first and second exhaust pipes, significantly improving exhaust efficiency.

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0031] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0032] refer to Figure 1-5 An embodiment of the present invention shows a true boiling water outlet, including a housing 1, wherein a water vapor separation chamber 11 is provided inside the housing 1, and a water outlet channel 13, a first output chamber 14 and a second output chamber 15 are provided below the water vapor separation chamber 11.
[0033] The water vapor separation chamber 11 is connected to the water inlet end 12; the top end of the water outlet channel 13 is connected to the water vapor separation chamber 11; the bottom of the first output chamber 14 is provided with a first opening (not marked in the figure), and the top of the first output chamber 14 is connected to the water vapor separation chamber 11 through a first exhaust pipe 141, the top end of the first exhaust pipe 141 being higher than the top end of the water outlet channel 13; the bottom of the second output chamber 15 is provided with a second opening (not marked in the figure), and the top of the second output chamber 15 is connected to the water vapor separation chamber 11 through a second exhaust pipe 151, the top end of the second exhaust pipe 151 being higher than the top end of the first exhaust pipe 141.
[0034] The true boiling water outlet features a multi-stage steam exhaust structure created by incorporating a first exhaust pipe 141 and a second exhaust pipe 151 within the water-vapor separation chamber 11. When boiling water mixed with steam enters the water-vapor separation chamber 11 from the inlet 12, the water is discharged from the outlet channel 13 under gravity, while the steam rises and escapes through the first exhaust pipe 141 and the second exhaust pipe 151 to the first output chamber 14 and the second output chamber 15. Thus, when faced with a large amount of steam generated during true boiling, the steam can be discharged together through the first exhaust pipe 141 and the second exhaust pipe 151, greatly improving exhaust efficiency. The steam can be discharged from the water-vapor separation chamber 11 in a timely and effective manner, effectively preventing unstable water output and spraying water caused by steam accumulation. This ensures the stability of the water output from the water purifier during true boiling, reduces the risk of scalding for users, and improves the safety of using the water purifier.
[0035] This true boiling water outlet has a unique design advantage when outputting non-boiling water (water with low steam content, such as cold or warm water). When a large flow rate of drainage is required, the first vent pipe can be temporarily used for drainage, increasing the water output of the outlet. Specifically, non-boiling water enters the water-vapor separation chamber 11. When the non-boiling water flow rate is large (the inflow rate is greater than the outflow rate of the outlet channel 13), the outlet channel 13 cannot drain the water in time. When the liquid level in the water-vapor separation chamber 11 is higher than the top of the first drain pipe 141, water will enter the first drain pipe 141 and flow out from the first output chamber 14, thereby increasing the water output. At the same time, the second drain pipe 151 is still used for venting steam. Therefore, when the steam content of the non-boiling water is low, the flow rate can be increased, increasing the water output of the true boiling water outlet. Thus, this true boiling water outlet can adapt to situations requiring true boiling water output as well as situations requiring a large flow rate of non-boiling water output.
[0036] In some embodiments, such as Figure 2 As shown, the first output cavity 14 is annular and is arranged around the outside of the water outlet channel 13; the second output cavity 15 is annular and is arranged around the outside of the first output cavity 14.
[0037] Thus, when the flow rate is high, the first output chamber 14 is temporarily used for drainage, and the water discharged from the first output chamber 14 and the water outlet channel 13 can maintain a water jet, making it convenient for users to collect water.
[0038] In some embodiments, such as Figure 1-5 As shown, it also includes an ultraviolet sterilization module 2, which includes an ultraviolet lamp 21 that irradiates the water vapor separation chamber 11. When the ultraviolet lamp 21 irradiates the water, it can destroy the DNA or RNA structure of bacteria, viruses, and other microorganisms, rendering them unable to reproduce and survive. This effectively kills various microorganisms that may exist in the water vapor separation chamber 11, including common pathogenic bacteria such as Escherichia coli and Staphylococcus aureus, as well as some heat-resistant Bacillus species, providing a more reliable guarantee for the safety of the water dispensed from the drinking water machine.
[0039] Specifically, the above scheme is as follows: Figure 2 and Figure 5 As shown, the ultraviolet sterilization module 2 includes a transfer cylinder 22, which is hollow inside. The ultraviolet lamp 21 is disposed on the top of the transfer cylinder 22, and a mesh plate 23 is provided at the bottom of the transfer cylinder 22. An overflow hole 221 communicating with the water vapor separation chamber 11 is opened on the side wall of the transfer cylinder 22. The mesh plate 23 is blocked on the water inlet end 12.
[0040] The mesh plate 23 filters the water entering the transfer cylinder 22, preventing large particles from entering the water-vapor separation chamber 11. The overflow hole 221 on the transfer cylinder 22 extends the water residence time, increasing the contact time between the water and ultraviolet light, allowing the ultraviolet light to act on the microorganisms in the water more effectively, thereby improving sterilization efficiency and better killing various harmful microorganisms. The overflow hole 221 on the side wall of the transfer cylinder 22, which connects to the water-vapor separation chamber 11, acts as a water flow buffer. When the water flow rate at the inlet 12 is large, the water will not rush directly and quickly into the water-vapor separation chamber 11, preventing high-pressure boiling water from being directly sprayed into the first exhaust pipe 141 and the second exhaust pipe 151.
[0041] Furthermore, such as Figure 2 and Figure 4 As shown, a baffle 16 is provided inside the water vapor separation chamber 11, and the baffle 16 is located outside the overflow hole 221. By blocking the water flow from the overflow hole 221, it is further ensured that the water flowing out of the overflow hole 221 will not be directly sprayed onto the first exhaust pipe 141 and the second exhaust pipe 151.
[0042] Specifically, the above scheme is as follows: Figure 5 As shown, the ultraviolet sterilization module 2 also includes a circuit board 25 and a transparent partition 24. The transparent partition 24 is disposed between the ultraviolet lamp 21 and the transfer cylinder 22. The circuit board 25 is electrically connected to the ultraviolet lamp 21, and the transparent partition 24 is sealed to the transfer cylinder 22. The transparent partition 24 ensures that the ultraviolet lamp 21 is separated from water, preventing short circuits and damage.
[0043] Specifically, the above scheme is as follows: Figure 4 As shown, the water inlet 12 forms an upward-facing inlet 121 within the water vapor separation chamber 11. The bottom of the transfer cylinder 22 is inserted into the inlet 121, and the transfer cylinder 22 and the inlet 121 are sealed together. Thus, after water enters from the water inlet 12, it first enters the transfer cylinder 22 and then the water vapor separation chamber 11, ensuring that all water is filtered by the mesh plate 23 and irradiated by the ultraviolet lamp 21.
[0044] Specifically, for ease of assembly and disassembly, the above solution includes, for example... Figure 2 and Figure 4 As shown, the top of the housing 1 is provided with an insertion hole 17 for inserting the ultraviolet sterilization module 2, and the ultraviolet sterilization module 2 is screwed to the housing 1.
[0045] In summary, this application provides a true boiling water outlet that effectively separates water vapor, solving the problem of water vapor separation caused by large boiling water flow rates, thus enabling the direct drinking water machine to dispense truly boiling water. This not only improves the quality of drinking water, allowing users to enjoy healthier and purer boiling water.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
