Description

Technical Field

[0001] The utility model belongs to the technical field of humidifying equipment, and particularly relates to a water-separated silent evaporation humidifier. Background Art

[0002] In the prior art, an evaporation humidifier mainly comprises a water tank, an evaporator and a fan. The lower end of the evaporator is immersed in the water tank. Through the siphon principle of capillaries, the evaporator absorbs water and becomes wet, and then the fan blows out the moisture of the evaporator to realize humidification. However, since the existing fan is usually directly installed in the housing of the humidifier, the noise generated by the fan mainly depends on the side wall of the housing for blocking. However, due to the limited wall thickness of the housing, the blocking effect on noise is limited, resulting in excessive noise of the humidifier during daily use and poor use experience. Therefore, it is very necessary to develop an evaporation humidifier that can effectively block the noise of the fan. Object of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a water-separated silent evaporation humidifier.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A water-separated silent evaporation humidifier, comprising a main body and a water tank. The main body comprises a housing and an upper cover. The upper side of the housing is open, and the upper cover is arranged on the upper side of the housing. The housing and the upper cover enclose to form an air duct. An upper water tank located above the air duct is arranged on the upper side of the upper cover. A lower water tank located below the air duct is arranged in the housing. A grille extending towards the lower water tank is annularly arranged at the bottom of the upper cover. An annular evaporator is coated outside the grille. A preset distance is left between the evaporator and the side wall of the housing. A water outlet is arranged at the side part of the upper water tank. The upper end of the evaporator covers outside the water outlet, and the lower end is placed in the lower water tank. A blowing device is arranged in the air duct on the radial inner side of the grille. The blowing device is used for sending air into the air duct, and is provided with an air outlet facing the evaporator. The main body is also configured with a control component. The water tank can be controlled by the control component to convey water to the upper water tank.

[0006] Compared with the prior art, by arranging the blowing device on the radial inner side of the evaporator and surrounding the blowing device with the evaporator, when the evaporator works, it will be wetted under the action of the control component, resulting in the noise generated by the blowing device needing to pass through multiple structures such as the evaporator itself, water molecules, and the outer wall of the main body before spreading to the outside of the humidifier. Additionally, by setting a spacing between the evaporator and the outer wall of the main body, the path of noise propagation can be extended to prevent sound waves from directly transmitting to the side wall of the housing. At the same time, the water in the upper water tank flows through the water outlet, passes through the evaporator, and then enters the lower water tank. The above method blocks the longitudinal propagation of noise by setting the upper water tank and the lower water tank. Therefore, the propagation of noise can be effectively blocked on the peripheral side, upper side, and lower side of the main body, improving the sound insulation effect and the user experience.

[0007] Further, the water tank is detachably installed on the upper side of the main body and is provided with a water discharge valve facing the upper water tank. The water discharge valve can be controlled by the control component to open and supply water to the upper water tank, and the water body enters the lower water tank after flowing through the evaporator through the water outlet.

[0008] Further, the control component includes a floating switch arranged at the bottom of the lower water tank. The floating switch is configured with a push rod extending upward to the upper water tank. The push rod can be controlled by the floating switch to rise as the liquid level in the lower water tank drops, thereby pushing open the water discharge valve, or the push rod can be controlled by the floating switch to drop as the liquid level in the lower water tank rises, thereby closing the water discharge valve. The above control component adopts a mechanical control method and can complete the water discharge of the water tank without setting a power pump. Therefore, the power pump is omitted, which is not only quieter but also lower in cost.

[0009] Further, the floating switch includes a rocker and a bracket. One end of the rocker is set as a linkage end for cooperating with the push rod, and the opposite end is provided with a floating plate whose weight is greater than that of the linkage end. The rocker is provided with a rotating shaft hinged to the bracket between the linkage end and the floating plate.

[0010] Further, the bracket includes a fixed seat hinged to the rotating shaft and a shaft cylinder connected to the upper end of the fixed seat. The push rod can movably penetrate upward through the shaft cylinder.

[0011] Further, the fixed seat is fixedly connected to the housing, or the upper end of the shaft cylinder is fixedly connected to the upper cover. The above setting method facilitates integrating the control component on the housing or the upper cover, so it is convenient for installation and disassembly.

[0012] Further, the evaporator is an annular humidifying curtain, and the material of the humidifying curtain is at least one of plant fiber material, polymer material, and non-woven fabric material.

[0013] Further, the preset spacing is N times the thickness of the evaporator, where N is greater than or equal to 1.

[0014] Further, a plurality of air outlets (32) are annularly arranged on the upper end of the main body (100) around the periphery of the upper water tank (31), and the annular air outlets can discharge air 360 degrees. Description of the Drawings

[0020] The following is a preferred detailed embodiment of the present invention in conjunction with the accompanying drawings.

[0021] See Figures 1 to 3 , this embodiment provides a water-separated and silent evaporation humidifier, including a main body 100 and a water tank 2. The main body 100 includes a housing 1 and an upper cover 3. The upper side of the housing 1 is open, and a lower water tank 11 is formed at its bottom. The upper cover 3 is covered on the upper end of the housing 1, and an upper water tank 31 is formed at its upper end. A wind channel 13 is formed between the housing 1 and the upper cover 3. The above-mentioned upper water tank 31 and lower water tank 11 are respectively located at the upper and lower ends of the wind channel 13. An evaporator 14 is annularly arranged in the wind channel 13. A water outlet 15 is opened on the side of the upper water tank 31. The lower end of the evaporator 14 is placed in the lower water tank 11, and its upper end extends upward to cover the outside of the water outlet 15. The water tank 2 is detachably installed on the upper side of the main body 100, and is provided with a water discharge valve 21 facing the upper water tank 31. The main body 100 is also provided with a control component for controlling the water supply from the water tank 2 to the evaporator 14 to moisten the evaporator 14. The control component includes a floating switch 4 arranged at the bottom of the lower water tank 11. The floating switch 4 is provided with a push rod 41 extending upward to the upper water tank 31. The floating switch 4 can control the lifting of the push rod 41 according to the liquid level change in the lower water tank 11. Specifically, as the liquid level in the lower water tank 11 drops, the floating switch 4 drives the push rod 41 to gradually rise. When it rises to a certain position, it can push open the water discharge valve 21, driving the water in the water tank 2 to flow into the upper water tank 31, and flowing through the evaporator 14 from the water outlet 15 into the lower water tank 11. When the liquid level in the lower water tank 11 rises, the floating switch 4 drives the push rod 41 to gradually descend. When it descends to a certain position, it separates from the water discharge valve 21, thereby closing the water discharge valve 21 to stop the water supply.

[0022] In the present utility model, the water tank 2 is placed above. At the same time, an upper water tank 31 is arranged at the upper end of the air duct 13, and a lower water tank 11 is arranged at the lower end. A floating switch 4 that can change with the liquid level is arranged in the lower water tank 11, and a push rod 41 linked with the floating switch 4 is arranged. The push rod 41 extends to the upper water tank 31 to control the water discharge valve 21 of the water tank 2. Thus, the water supply of the water tank 2 to the upper water tank 31 is controlled according to the liquid level condition of the lower water tank 11. The water body in the upper water tank 31 flows to the upper end of the evaporator 14 through the water discharge port 15 on the side, so as to wet the evaporator 14 from top to bottom. At the same time, since the lower part of the evaporator 14 is immersed in the lower water tank 11, the humidity of the evaporator 14 is effectively increased. This mechanical upper water supply and wetting method does not require an additional power pump for spraying the evaporator 14, and can also ensure the humidification effect. It not only has low cost but also low noise.

[0023] See Figures 2 to 4 , a grille 30 supported on the lower water tank 11 is provided in a circular shape at the bottom of the upper cover 3. The evaporator 14 is arranged in a circular shape between the grille 30 and the side wall of the housing 1. The upper cover 3 is provided with a plurality of air discharge ports 32 located above the evaporator 14 and arranged in a circular shape around the upper water tank 31. Specifically, the evaporator 14 is a humidifying curtain, and the humidifying curtain has a certain elasticity and is tightly sleeved on the outer periphery of the grille 30; the material of the humidifying curtain can be a plant fiber material, such as wood pulp paper, spunlace cloth, or a polymer material, non-woven fabric material, felt cloth, etc. The above grille 30 is used to fix the evaporator 14, which is convenient for disassembly, washing and replacement of the evaporator 14. Just disassemble the upper cover 3 and the evaporator 14 can be taken out together.

[0024] See Figures 2 to 5 , the floating switch 4 includes a rocker 42 and a bracket 43. One end of the rocker 42 is set as a linkage end 421 for cooperating with the push rod 41, and a floating plate 422 with a weight greater than that of the linkage end 421 is arranged at the opposite end. A rotating shaft 423 hinged with the bracket 43 is arranged between the linkage end 421 and the floating plate 422 of the rocker 42. The bracket 43 includes a fixed seat 431 hinged with the rotating shaft 423 and a shaft cylinder 432 connected to the upper end of the fixed seat 431. The push rod 41 can movably penetrate upward through the shaft cylinder 432. In a specific setting mode, the fixed seat 431 is fixedly connected with the housing 1, or the upper end of the shaft cylinder 432 is fixedly connected with the upper cover 3. When the fixed seat 431 is fixedly connected with the housing 1, the floating switch 4 and the push rod 41 are integrated on the housing 1, so it is convenient for disassembly, assembly and cleaning of the upper cover 3. When the shaft cylinder 432 is connected to the bottom of the upper cover 3, the floating switch 4 and the push rod 41 are integrated on the upper cover 3, so it is convenient for disassembly, assembly and cleaning of the housing 1.

[0025] See Figures 1 to 4, in a specific embodiment, the host 100 further includes a base 5, and the housing 1 is detachably mounted on the base 5. Specifically, the water sink 11 is provided with a positioning convex portion 18 extending downward, and the base 5 is provided with an assembly groove 51 with an upward opening corresponding to the positioning convex portion 18. The positioning convex portion 18 is detachably inserted into the assembly groove 51. By providing the positioning convex portion 18 and the assembly groove 51, the quick positioning and installation of the housing 1 can be realized, and the positioning convex portion 18 can improve the assembly stability between the housing 1 and the base 5.

[0026] See Figures 2 to 4 , a blowing device 6 for blowing air into the air duct 13 is provided on the base 5. The blowing device 6 includes a wind hood 61 provided on the base 5 and an impeller 62 provided in the wind hood 61. An air outlet 63 is formed on the side of the wind hood 61, and an air inlet 64 penetrating the base 5 is provided at the bottom thereof. A through hole 16 is formed in the housing 1 corresponding to the wind hood 61. When the housing 1 is mounted on the base 5, the blowing device 6 enters the air duct 13 through the through hole 16 and is placed radially inside the grille 30, and its air outlet 63 faces the evaporator 14. When the impeller 62 is started, air enters the air inlet 64 from the bottom of the base 5 and blows to the evaporator 14 through the air outlet 63, thereby taking out moisture to achieve humidification. By arranging the blowing device 6 radially inside the evaporator 14, the evaporator 14 surrounds the blowing device 6. When the evaporator 16 works, it will be wetted under the action of the control component, resulting in the noise generated by the blowing device 6 needing to pass through multiple structures such as the evaporator 14 itself, water molecules, and the housing 1 before spreading to the outside of the humidifier. Therefore, the propagation of noise is effectively blocked, the sound insulation effect is improved, and the use experience is enhanced. And the upper side of the blowing device is covered by the upper cover 3, and the lower side is blocked by the water sink 11. Therefore, the noise is effectively isolated in the air duct 13, thereby reducing the noise of the humidifier.

[0027] See Figures 2 to 4 , the housing 1 has a housing bottom wall 101 and a housing side wall 102 provided on the periphery of the housing bottom wall 101. The housing side wall 102 and the bottom shell bottom wall 101 enclose to form the water sink 11. A preset distance is left between the housing side wall 102 and the evaporator 14. The preset distance is N times the thickness of the evaporator, where N is greater than or equal to 1. Multiple barriers for blocking the propagation of noise are formed by the housing side wall 102, the preset distance, the evaporator 14, and the grille 30. Therefore, the noise of the humidifier is effectively controlled.

[0028] See Figures 2 to 4 , in order to prevent water from flowing out of the through hole 16, the positioning convex portion 18 is provided with a water blocking wall 17 extending upward and surrounding the outer periphery of the bottom of the wind hood 61 around the through hole 16.

[0029] See Figures 2 to 4, a positioning groove 33 extending upward is provided at the bottom of the upper cover 3 corresponding to the air duct cover 61, the upper end of the air duct cover 61 is detachably embedded in the positioning groove 33, and an upward protruding upper protruding portion 34 is formed at the bottom of the upper water tank 31 by the positioning groove 33. A bottom edge 22 is provided at the bottom of the water tank 2 corresponding to the upper protruding portion 34, and the bottom edge 22 presses against the upper side of the upper protruding portion 34 to support the water tank 2.

[0030] See Figure 2 and Figure 4 , a convex edge 24 inserted into the edge of the upper water tank 31 is provided around the bottom of the water tank 2, and the water discharge valve 21 is arranged radially inside the convex edge 24. The convex edge 24 can limit the position of the water tank 2. A reinforcing rib 35 connected to the upper cover 3 is provided on the side of the upper protruding portion 34, and a notch 23 engaged with the reinforcing rib 35 is provided on the water tank 2. Thereby, the positioning of the water tank 2 is further carried out, and the strength of the structure of the upper cover 3 can be improved.

[0031] The evaporation humidifier of the present utility model adopts a split upper cover 3, a housing 1, a base 5 and a water tank 2, realizing a modular assembly structure. By separating the components that need to be cleaned and those that do not need to be cleaned, the disassembly and cleaning are more convenient. Specifically, by integrating the blowing device 6 on the base 5, and integrating the components that will contact water such as the upper water tank, the lower water tank, and the evaporator on the main body 100, the components that need to be cleaned and those that do not need to be cleaned are separated. Therefore, the main body 100 can be directly disassembled and directly rinsed or soaked for daily maintenance without worrying about damage to the charged components on the base 5. Coupled with the fact that the upper cover 3 and the housing 1 of the main body 100 are separated structures, it is easier to directly clean the structures such as the air duct 13 and the evaporator 14 inside. At the same time, the air duct 13 formed by the present utility model has a simple structure. Air enters from the bottom of the humidifier, blows to the evaporator 14 after passing through the blowing device 6 and is blown out from the upper air outlet 32. Compared with the complex air ducts 13 of existing humidifiers, the humidifier of the present utility model has smoother air output and better humidification effect.

[0032] Moreover, the structure of this humidifier is more compact, optimizing the volume of the product. In traditional humidifiers, the various structural modules are often only assembled on the surface. The structural modules are designed separately with independent functions, resulting in a relatively large overall volume of the humidifier product after later assembly. In this patent, the combination of the upper cover 3 and the housing 1 forms the air duct 13. The blowing device 6 is arranged on the base 5, and the detachable combination of the base 5 and the housing 1 is used to enable the blowing device 6 to enter and exit the air duct 13. At the same time, a positioning groove 33 for fixing the blowing device 6 is provided at the bottom of the upper cover 3 to achieve the limit of the blowing device 6. In addition, a water trough 11 is provided at the bottom of the housing 1 and a water trough 31 is provided on the upper side of the upper cover 3, and their functions are associated by using the floating switch 4 and the push rod 41, so that a downward water path from top to bottom and a siphon path from bottom to top are formed on the evaporator 14. Therefore, the various structural modules are interrelated and combined with each other, and the redundancy of their respective spaces is used to complete the assembly and space optimization, effectively reducing the volume of the product and the space it occupies.

[0033] Regarding the air outlet mode of the present utility model, the combination of the above-mentioned air outlet 32 and the air duct 13 constitutes a simple and straight air outlet channel. Air enters from the bottom air inlet 64 through the blowing device 6, is discharged into the air duct 13, and blows towards the evaporator 14, carrying moisture and going straight up, and is blown out from the top air outlet 32. This air outlet mode from bottom to top ensures that the wind blown by the blowing device 6 can flow through the entire evaporator 14, ensuring the maximum humidification amount. The annular air outlet 32 can blow air in a large range of 360 degrees.

[0034] According to the disclosure and teachings of the above specification, those skilled in the art of the present utility model can also make changes and modifications to the above-mentioned embodiments. Therefore, the present utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present utility model should also fall within the protection scope of the claims of the present utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model.
