Description

Technical Field

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

[0002] In the prior art, an evaporative humidifier mainly includes 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 then the fan blows air through the evaporator to carry away water vapor to achieve the humidifying effect. Compared with a high-temperature boiling humidifier, the evaporative humidifier lacks a high-temperature boiling module. Since water will generate a large boiling noise when boiling, the evaporative humidifier is quieter and is also widely popular. However, for this type of evaporative humidifier, only the bottom of its evaporator is immersed in water, and the water in the water tank needs to spread from bottom to top. In actual use, the top of the evaporator is often dry, resulting in uneven humidity of the evaporator and a decrease in the humidifying efficiency. Therefore, it is very necessary to develop a humidifier that can improve the humidity of the evaporator and has low noise. Summary of the Invention

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

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

The main body is configured with an air duct, a lower water tank located at the upper end of the air duct, an immersion water tank located at the lower end of the air duct, and an evaporator disposed in the air duct. A water outlet is formed on the side of the lower water tank. The lower end of the evaporator is placed in the immersion water tank, and the upper end extends upward to cover the outside of the water outlet. The water tank is detachably installed on the upper side of the main body and is configured with a water outlet valve facing the lower water tank. A floating switch is provided at the bottom of the immersion water tank. The floating switch is configured with a push rod extending upward to the lower water tank. The push rod can be controlled by the floating switch to rise as the liquid level of the immersion water tank drops, so as to push open the water outlet valve to drive water to flow into the lower water tank, and flow through the evaporator from the water outlet into the immersion water tank. Or, the push rod can be controlled by the floating switch to drop as the liquid level of the immersion water tank rises, so as to close the water outlet valve.

The water body in the water discharge groove flows to the upper end of the evaporator through the water discharge port on the side, so as to wet the evaporator from top to bottom. At the same time, since the lower part of the evaporator is immersed in the water immersion groove, the humidity of the evaporator is effectively increased. This mechanical upper water inlet wetting method does not require an additional power pump for spraying the evaporator, and can also ensure the humidification effect, with low cost and low noise.

[0019] The following describes a preferred specific embodiment of the present invention with reference to the accompanying drawings.

[0020] See Figures 1 to 3 , this embodiment provides a humidifier with a mechanical silent evaporation water path, 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 water immersion tank 11 is formed at its bottom. The upper cover 3 is covered on the upper end of the housing 1, and a water drainage tank 31 is formed at its upper end. A wind duct 13 is formed between the housing 1 and the upper cover 3. The above-mentioned water drainage tank 31 and water immersion tank 11 are respectively located at the upper end and the lower end of the wind duct 13. An evaporator 14 is arranged inside the wind duct 13 in a ring shape. A water drainage port 15 is opened on the side of the water drainage tank 31. The lower end of the evaporator 14 is placed in the water immersion tank 11, and its upper end extends upward to cover the outside of the water drainage port 15. The water tank 2 is detachably installed on the upper side of the main body 100, and is configured with a water drainage valve 21 facing the water drainage tank 31. A floating switch 4 is arranged at the bottom of the water immersion tank 11. The floating switch 4 is configured with a push rod 41 extending upward to the water drainage tank 31. The floating switch 4 can control the lifting of the push rod 41 according to the liquid level change in the water immersion tank 11. Specifically, as the liquid level in the water immersion 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 drainage valve 21, driving the water in the water tank 2 to flow into the water drainage tank 31, and flowing through the evaporator 14 from the water drainage port 15 into the water immersion tank 11. When the liquid level in the water immersion 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 drainage valve 21, thereby closing the water drainage valve 21 to stop the water drainage.

[0021] In this utility model, the water tank 2 is placed above, and at the upper end of the air duct 13, a water trough 31 is provided, and at the lower end, a soaking trough 11 is provided. A floating switch 4 that can change with the liquid level is arranged in the soaking trough 11, and a push rod 41 linked with the floating switch 4 is arranged. The push rod 41 extends to the water trough 31 to control the water inlet valve 21 of the water tank 2. Thus, according to the liquid level condition of the soaking trough 11, the water tank 2 is controlled to replenish water to the water trough 31. The water body in the water trough 31 flows to the upper end of the evaporator 14 through the water outlet 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 soaking trough 11, the humidity of the evaporator 14 is effectively increased. This mechanical upper water inlet 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.

[0022] See Figures 2 to 4 , a grille 30 supported on the soaking trough 11 is annularly arranged at the bottom of the upper cover 3. The evaporator 14 is annularly arranged between the grille 30 and the side wall of the housing 1. The upper cover 3 is provided with a plurality of air vents 32 located above the evaporator 14 and annularly arranged around the water trough 31. Specifically, the evaporator 14 is an annular 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 or 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 the disassembly, washing and replacement of the evaporator 14. Only by disassembling the upper cover 3 can the evaporator 14 be taken out together.

[0023] 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 the relative end is provided with a floating plate 422 whose weight is greater than that of the linkage end 421. 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 the disassembly, installation 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 the disassembly, installation and cleaning of the housing 1.

[0024] 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 immersion tank 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, quick positioning and installation of the housing 1 can be achieved, and the positioning convex portion 18 can improve the assembly stability between the housing 1 and the base 5.

[0025] 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. The housing 1 is provided with a through hole 16 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 its air outlet 63 faces the evaporator 14. When the impeller 62 is started, air enters from the bottom of the base 5 into the air inlet 64 and is blown to the evaporator 14 through the air outlet 63, thereby taking out moisture to achieve humidification. Since the blowing device 6 is provided in the air duct 13, its upper side is covered by the upper cover 3, and the outer side is successively provided with the outer side wall of the housing 1, the humidifying evaporator 14, and the grille 30. Therefore, the noise is effectively isolated in the air duct 13, thereby reducing the noise of the humidifier.

[0026] See Figures 2 to 4 , the housing 1 has a housing bottom wall 101 and a housing side wall 102 provided around the housing bottom wall 101. The housing side wall 102 and the bottom shell bottom wall 101 enclose the immersion tank 11. A preset distance is left between the housing side wall 102 and the evaporator 14. Multiple barriers for blocking noise propagation 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.

[0027] 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.

[0028] See Figures 2 to 4 , the bottom of the upper cover 3 is provided with a positioning groove 33 extending upward corresponding to the wind hood 61. The upper end of the wind hood 61 is detachably embedded in the positioning groove 33. The positioning groove 33 forms an upward convex upper convex portion 34 at the bottom of the water tank 31. The bottom of the water tank 2 is provided with a bottom edge 22 corresponding to the upper convex portion 34. The bottom edge 22 presses against the upper side of the upper convex portion 34, thereby supporting the water tank 2.

[0029] See Figure 2 and Figure 4, a convex edge 24 inserted into the edge of the water discharge groove 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 convex part 34, and a notch 23 for clamping with the reinforcing rib 35 is provided on the convex edge 24. 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.

[0030] 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 come into contact with water such as the water discharge groove, the immersion 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.

[0031] Moreover, the structure of this humidifier is more compact, optimizing the volume of the product. The various structural modules of traditional humidifiers are often only surface-mounted and combined. The structural modules are designed separately and have independent functions, resulting in a relatively large overall volume of the assembled humidifier product. However, in this patent, the upper cover 3 and the housing 1 are combined to form 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 realize the entry and exit of the blowing device 6 into and out of 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 realize the limit of the blowing device 6. In addition, an immersion tank 11 and a water discharge groove 31 are respectively provided at the bottom of the housing 1 and the upper side of the upper cover 3, and the functions of the two are associated by using the floating switch 4 and the push rod 41, so as to form a downward water path and an upward siphon path from top to bottom on the evaporator 14. Therefore, the various structural modules are interrelated and combined with each other, using the redundancy of their respective spaces to complete the assembly and space optimization, effectively reducing the volume of the product and the space it occupies.

[0032] For 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, is discharged into the air duct 13 via the blowing device 6, 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 out by the blowing device 6 can flow through the entire evaporator 14, ensuring the maximum humidification amount, and the annular air outlet 32 can blow out air in a large range of 360 degrees.

[0033] According to the disclosure and teaching 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.
