Technical Field

[0001] This utility model relates to the field of humidifier technology, and in particular to a water discharge structure and humidification device. Background Technology

[0002] Humidifiers using a top-fill system typically have an upper water tank or upper water inlet at the top. This upper tank / inlet is connected to a lower water tank at the bottom via a drain pipe. To add water, it is added through the upper tank / inlet, and the water flows into the lower water tank through the drain pipe. During the water filling process, outside air can get into the drain pipe. This trapped air can affect the water flow rate and generate filling noise.

[0003] In existing technologies, to address the problem of trapped air in drain pipes, some methods involve creating vents on the side wall of the drain pipe near the drain tank. This allows the air to escape, eliminating noise caused by poor venting. However, this design is prone to water leakage from the vent, posing a safety hazard. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] The following is combined with Figures 1-5 This invention describes the drainage structure and humidification device of an embodiment of the present invention.

[0021] like Figure 1-3 As shown, this utility model embodiment provides a drainage structure, which is disposed between a first tank 1 and a second tank 2 arranged vertically, and includes: a first pipe 3 and a second pipe 4; the water inlet end of the first pipe 3 is connected to the water outlet of the first tank 1, and the water outlet end 32 of the first pipe 3 is connected to the water inlet of the second tank 2; one end of the second pipe 4 is disposed on the side wall of the first pipe 3 and communicates with the first pipe 3, and the other end of the second pipe 4 extends toward the side opposite to the water flow direction in the first pipe 3 and communicates with the atmosphere, for discharging the air in the first pipe 3.

[0022] Specifically, the embodiment provided by this utility model connects the second pipe 4 to the side wall of the first pipe 3, and the other end of the second pipe 4 is connected to the atmosphere, which can smoothly discharge the air in the first pipe 3. At the same time, since the opening end of the second pipe 4 faces the opposite direction of the water flow, there is no risk of water leakage. The water flowing from the first pipe 3 to the second pipe 4 will eventually flow back to the first pipe 3. The structural design is scientific and reasonable, solves the air exhaust problem, and has strong stability and safety.

[0023] It should be understood that the first tank 1 is provided with a water inlet for water supply; the first pipe 3 is connected to the first tank 1 and the second tank 2 respectively, and the second tank 2 is provided with a water inlet for receiving the water input from the first pipe 3.

[0024] In some possible implementations, the first tube 3 is blow-molded and can be made into an irregular shape to fit the internal structural layout of the humidifier, which is low in cost and easy to arrange; the outer walls of the first tube 3 and the second tube 4 are provided with screw holes, and the first tube 3 and / or the second tube 4 can be fixed to the internal structural components of the humidifier by screws; it should be understood that the fixing method of the first tube 3 and / or the second tube 4 is not limited to screws, but can also be other fixing methods such as rivets and welding.

[0025] In some possible implementations, the connection end of the second tube 4 and the first tube 3 has a height difference of 100 mm with the end of the second tube 4 that communicates with the air; it is understood that in other implementations, the above height difference may be other dimensions depending on actual needs, and is not specifically limited here.

[0026] like Figure 4 As shown, according to an embodiment of the present utility model, a drainage structure is provided in which a plug-in portion 11 is formed circumferentially at the outlet of the first housing 1, and the plug-in portion 11 extends outward along the axial direction of the outlet of the first housing; and a plug-in groove 31 is formed at the inlet end of the first pipe 3 to cooperate with the plug-in portion 11.

[0027] In some possible implementations, the insertion part 11 is cylindrical, and the insertion groove 31 is a cylindrical structure with an inner diameter larger than that of the insertion part 11. The outer surface of the insertion part 11 and the inner wall surface of the insertion groove 31 are tightly fitted to form a tight connection.

[0028] like Figure 4 As shown, a drainage structure provided according to an embodiment of the present utility model further includes: a sealing member 5, which is disposed on the mating surface of the insertion part 11 and the insertion groove 31; the sealing member 5 has a groove 51, the insertion part 11 is inserted into the groove 51, and the groove 51 is pressed against the insertion groove 31.

[0029] In some possible implementations, the seal 5 is a silicone sealing sleeve. The seal 5 is annular in shape and is embedded in the mating surface of the insertion part 11 and the insertion groove 31. This enhances the fit between the insertion part 11 and the insertion groove 31, and increases the airtightness and waterproof performance of the connection. When the first pipe body 3 is connected to the outlet of the first box 1, the seal 5 is fitted onto the drain outlet of the first box 1, and the inlet end of the first pipe body 3 is fitted onto the seal 5, forming a double sealing connection. A groove 51 is provided inside the sleeve of the seal 5. The groove 51 is U-shaped, and at least part of the insertion part 11 is inserted into the groove 51 to form an internal seal, thereby improving the sealing effect between the first pipe body 3 and the first box 1.

[0030] like Figure 4 As shown, according to an embodiment of the present invention, a drainage structure is provided with a limiting part 12 on the outer peripheral side wall of the insertion part 11, and the insertion groove 31 is pressed into the limiting part 12.

[0031] In some possible implementations, the limiting part 12 can be integrally formed with the insertion part 11, and its shape is an annular protrusion provided on the outer wall of the insertion part 11, which can abut against and press the annular boss 52 of the sealing member 5, further enhancing the connection sealing between the water inlet end of the first pipe body 3 and the water outlet of the first water tank.

[0032] like Figure 5 As shown, according to an embodiment of the present invention, the inner diameter of the outlet end 32 of the first pipe body 3 is gradually reduced along the water flow direction.

[0033] It should be understood that the lower end of the first pipe body 3 has a water outlet 32, which is connected to the water inlet of the second box body 2. The diameter of the water outlet 32 ​​of the first pipe body 3 gradually decreases along the water flow direction, forming a constricted structure, thereby preventing water from overflowing from the water outlet 32 ​​due to excessively fast water flow.

[0034] like Figure 5 As shown, according to an embodiment of the present invention, a drainage structure is provided in which the first pipe 3 is bent near the second housing 2 to facilitate connection with the water inlet of the second housing 2.

[0035] In some possible implementations, the lower end of the first tube 3 may also form a 90° bend as needed, so that the water outlet 32 ​​of the first tube 3 is aligned with the water inlet of the second housing 2. It should be understood that due to the space constraints of other internal components of the humidifier, the shape of the first tube 3 is not necessarily straight, and the first housing 1 and the second housing 2 are not necessarily strictly vertically aligned. Even if the positions of the first housing 1 and the second housing 2 are aligned, the water outlet of the first housing 1 and the water inlet of the second housing 2 may not be on the same straight line. Therefore, it is necessary to make some bending of the first tube 3 so that the water outlet 32 ​​of the first tube 3 can be aligned with the water inlet of the second housing 2.

[0036] like Figure 1-2 As shown, a drainage structure provided according to an embodiment of the present utility model further includes: a connecting part 6, one side of the connecting part 6 being connected to the side wall of the first pipe body 3, and the other side of the connecting part 6 being connected to the side wall of the second pipe body 4.

[0037] In some possible implementations, the connecting part 6 can be a connecting rib, and the two sides of the connecting part 6 can be connected and fixed to the side walls of the first tube 3 and the second tube 4 respectively by means of snapping, bonding or other methods; the connecting part 6 can be a continuous rib or a plate that is spaced apart in the length direction of the first tube 3 and the second tube 4, as long as it can meet the function of connecting the first tube 3 and the second tube 4.

[0038] It should be understood that the second tube 4 can be set separately, that is, the second tube 4 can be connected to the first tube 3 at only one end and fixed to the internal components of the humidifier by screws or other connecting parts; the second tube 4 can also be integrally formed with the first tube 3 or connected and fixed to the first tube 3 by the connecting part 6.

[0039] According to an embodiment of the present invention, a drainage structure further includes at least one connecting part, one end of which is disposed on the side wall of the first pipe body 3 and communicates with the first pipe body 3, and the other end of which is disposed on the side wall of the second pipe body 4 and communicates with the second pipe body 4.

[0040] It should be understood that in this embodiment, the connecting part connects the first pipe body 3 and the second pipe body 4, which means that the first pipe body 3 can be provided with multiple exhaust holes, and each exhaust hole is connected to the second pipe body 4 through its corresponding connecting part, which can improve exhaust efficiency and effect.

[0041] According to an embodiment of the present invention, a drainage structure is provided in which there are multiple second pipe bodies 4, and the multiple second pipe bodies 4 are evenly distributed on the first pipe body 3 along the water flow direction.

[0042] It should be understood that in this embodiment, multiple second pipes 4 can be provided, and the multiple second pipes 4 are respectively connected to the first pipe 3. This can also achieve the function of opening multiple exhaust holes on the first pipe 3. Moreover, the multiple second pipes 4 do not interfere with each other and have a better exhaust effect.

[0043] like Figure 1 As shown in the figure, this utility model embodiment also provides a humidification device, including the above-described drainage structure.

[0044] It is understood that the above-mentioned drainage structure can be applied to humidification devices as well as other devices that require water transfer. In this humidification device, the drainage structure is provided with a second pipe 4 on the first pipe 3 for venting. At the same time, excess water can flow back from the second pipe 4 to the first pipe 3, preventing water from leaking from the vent of the first pipe 3 and improving the safety of the humidification device.

[0045] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
