Description

Technical Field

[0001] The utility model belongs to the technical field of humidifying equipment, and particularly relates to an evaporative humidifier with an optimized and compact structure. Background Art

[0002] Although the existing evaporative humidifiers have been widely used in family and office environments to adjust the indoor humidity, there are still many deficiencies in their structural designs. Traditional humidifiers generally include independent components such as a base, a water trough, an evaporator, a water tank, and a fan. These components are often assembled only through simple mechanical connections during assembly, lacking tight integration and collaborative work in terms of functions. This design method results in independent functions among the components, lacking overall optimization, and further making the overall product structure bulky and significantly increasing the occupied space. In addition, the independently designed and developed components also increase the manufacturing difficulty and cost during the assembly process, which is not conducive to the market promotion of the product and the improvement of the user experience. Therefore, there is an urgent need for an evaporative humidifier that can achieve the functional integration and structural optimization of each component, thereby reducing the volume and saving space. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an evaporative humidifier with an optimized and compact structure.

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

[0005] An evaporative humidifier with an optimized and compact structure, comprising: a base, a main body, an evaporator, and a water tank.

[0006] The base is configured with an assembly groove with an open upper side. A fan stack protruding upward from the assembly groove is provided in the assembly groove. The fan stack is provided with an air outlet and an air inlet penetrating through the base.

[0007] The main body includes a housing and an upper cover. The upper side of the housing is open, and a water trough with a through hole is formed at the inner bottom. The upper cover is covered on the upper side of the housing and encloses a wind channel with the housing. An upper water trough with an open upper side is provided at the upper end of the upper cover. The bottom of the housing is detachably installed in the assembly groove. The fan stack penetrates through the through hole and extends into the wind channel. A positioning groove recessed upward is provided at the bottom of the upper cover. The upper end of the fan stack is embedded in the positioning groove. A water outlet communicating with the wind channel is opened at the side of the upper water trough.

[0008] The evaporator is arranged in the wind channel, with its lower end placed in the water trough and its upper end covering the outside of the water outlet.

[0009] A drain valve is provided at the bottom of the water tank, and a mounting seat is provided on the periphery of the drain valve. The mounting seat is inserted into the upper water tank. The drain valve can be operably opened to supply water to the upper water tank. Water flows through the evaporator and then enters the lower water tank through the drain port. The positioning groove protrudes upward to form an upper protrusion part located in the upper water tank. A bottom edge is provided at the bottom of the water tank corresponding to the upper protrusion part. The bottom edge presses against the upper side of the upper protrusion part, so the water tank can be supported.

[0010] Compared with the prior art, the structure of the present utility model is more compact, optimizing the volume of the product. The air duct is formed by the combination of the upper cover and the housing, and the blower stack is arranged on the base. The blower stack can enter and exit the air duct by using the detachable combination of the base and the housing. At the same time, a positioning groove for fixing the blower stack is provided at the bottom of the upper cover to realize the limit of the blower stack. In addition, a lower water tank and an upper water tank are respectively provided at the bottom of the housing and the upper side of the upper cover, and the water tank is detachably positioned and inserted into the upper water tank, thus forming a downward water path and an upward siphon path from top to bottom on the evaporator structure. Therefore, each structural module is interrelated and combined, 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.

[0011] Furthermore, the upper protrusion part is provided with a reinforcing rib connected to the upper cover, and the mounting seat is provided with a notch for clamping with the reinforcing rib. The reinforcing rib can, on the one hand, improve the strength of the upper cover, and on the other hand, can limit the water tank and perform positioning and assembly.

[0012] Furthermore, the ratio of the bottom area of the through hole to the lower water tank is less than or equal to 1:2; the ratio of the volume of the upper protrusion part to the upper water tank is less than or equal to 1:2. The above parameters can control the liquid storage capacity of the lower water tank and the upper water tank, ensure that there is enough liquid in the evaporator for humidification, and guarantee the humidification effect.

[0013] Furthermore, a grille extending towards the bottom of the housing is provided around the bottom of the upper cover. The evaporator is surrounded by the grille, and the air outlet faces the evaporator. The grille can be used to fix the evaporator.

[0014] Furthermore, the lower water tank is provided with a positioning convex part extending downward. The through hole is opened on the positioning convex part. The positioning convex part is detachably inserted into the assembly groove. The positioning convex part forms a stepped structure, and the housing can be positioned and assembled after being inserted into the assembly groove.

[0015] Furthermore, a water blocking wall extending upward and surrounding the periphery of the bottom of the blower stack is provided around the through hole. The water blocking wall can prevent the liquid in the lower water tank from leaking out and can improve the fitting tightness with the blower stack.

[0016] Further, the blower stack includes a wind hood disposed on the base and an impeller disposed within the wind hood. An air outlet is formed on the side of the wind hood, and an air inlet is provided at the bottom thereof. The top of the wind hood is embedded in the positioning groove.

[0017] Further, a water supply assembly is further included. The water supply assembly includes a floating switch disposed 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 of the lower water tank drops, so as to push open the drain valve. Or, the push rod can be controlled by the floating switch to drop as the liquid level of the lower water tank rises, so as to close the drain valve. The above water supply assembly adopts a mechanical control method and can complete the draining of the water tank without setting up a power pump. Therefore, the power pump is omitted, which is not only quieter but also lower in cost.

[0018] 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 having a weight greater than that of the linkage end. A rotating shaft hinged to the bracket is provided between the linkage end and the floating plate of the rocker.

[0019] 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.

[0020] 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 the integration of the water supply assembly on the housing or the upper cover, so it is convenient for installation and disassembly. Description of the Drawings

[0026] The following describes a preferred specific embodiment of the present invention with reference to the drawings.

[0027] See Figures 1 to 3 Figures 1 to 3 , this embodiment provides an evaporative humidifier with an optimized and compact structure, including a main unit 100, a base 5 and a water tank 2. The main unit 100 includes a housing 1 and an upper cover 3. The upper side of the housing 1 is open, and a water outlet groove 11 is formed at its bottom. The upper cover 3 is covered on the upper end of the housing 1, and a water inlet groove 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 inlet groove 31 and water outlet groove 11 are respectively located at the upper and lower ends of the wind duct 13. An evaporator 14 is provided inside the wind duct 13 in a circular shape. A water outlet 15 is opened on the side of the water inlet groove 31. The lower end of the evaporator 14 is placed in the water outlet groove 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 unit 100 and is configured with a water outlet valve 21 facing the water inlet groove 31. The main unit 100 is also configured with a water supply assembly for controlling the water outlet of the water tank 2 to moisten the evaporator 14. The water supply assembly includes a floating switch 4 provided at the bottom of the water outlet groove 11. The floating switch 4 is configured with a push rod 41 extending upward to the water inlet groove 31. The floating switch 4 can control the lifting of the push rod 41 according to the liquid level change in the water outlet groove 11. Specifically, as the liquid level in the water outlet groove 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 outlet valve 21, driving the water in the water tank 2 to flow into the water inlet groove 31, and flowing through the water outlet 15 through the evaporator 14 into the water outlet groove 11. When the liquid level in the water outlet groove 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 outlet valve 21, thereby closing the water outlet valve 21 to stop the water flow.

[0028] In this utility model, by placing the water tank 2 above, setting a water inlet groove 31 at the upper end of the wind duct 13, a water outlet groove 11 at the lower end, a floating switch 4 that can change with the liquid level in the water outlet groove 11, and a push rod 41 linked with the floating switch 4, the push rod 41 extends to the water inlet groove 31 to control the water outlet valve 21 of the water tank 2, thereby controlling the water supply from the water tank 2 to the water inlet groove 31 according to the liquid level condition of the water outlet groove 11. The water in the water inlet groove 31 flows to the upper end of the evaporator 14 through the water outlet 15 on the side, thus wetting the evaporator 14 from top to bottom. At the same time, since the lower part of the evaporator 14 is immersed in the water outlet groove 11, the humidity of the evaporator 14 is effectively improved. This mechanical upper water inlet wetting method does not require an additional power pump for spraying the evaporator 14, and can also ensure the humidifying effect. It not only has a low cost but also low noise.

[0029] See Figures 2 to 4, a grille 30 supported on the water sink 11 is provided around the bottom of the upper cover 3, the evaporator 14 is provided around between the grille 30 and the side wall of the housing 1, and the upper cover 3 is provided with a plurality of air vents 32 located above the evaporator 14 and provided around the periphery of the upper water tank 31. Specifically, the evaporator 14 is a humidifying curtain, 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 plant fiber materials such as wood pulp paper and spunlace cloth, or polymer materials, non-woven fabric materials, felt cloth, etc. The above grille 30 is used to fix the evaporator 14, which is convenient for the disassembly, cleaning and replacement of the evaporator 14. Just disassemble the upper cover 3 and the evaporator 14 can be taken out together.

[0030] 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 opposite end is provided with a floating plate 422 with a weight greater than that of the linkage end 421. A rotating shaft 423 hinged to the bracket 43 is provided between the linkage end 421 and the floating plate 422 of the rocker 42. The bracket 43 includes a fixed seat 431 hinged to the rotating shaft 423 and a shaft cylinder 432 connected to the upper end of the fixed seat 431. The push rod 41 is movably inserted upward through the shaft cylinder 432. In a specific setting mode, the fixed seat 431 is fixedly connected to the housing 1, or the upper end of the shaft cylinder 432 is fixedly connected to the upper cover 3. When the fixed seat 431 is fixedly connected to 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, 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 the disassembly, assembly and cleaning of the housing 1.

[0031] See Figures 1 to 4 , the housing 1 is detachably installed 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 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.

[0032] See Figures 2 to 4, a blower stack 6 for supplying air to the air duct 13 is provided on the base 5. The blower stack 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 its bottom. The housing 1 is provided with a through hole 16 corresponding to the wind hood 61. When the housing 1 is installed on the base 5, the blower stack 6 enters the air duct 13 through the through hole 16, so that it 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 towards the evaporator 14 through the air outlet 63, thereby taking out moisture to achieve humidification. By arranging the blower stack 6 radially inside the evaporator 14, the evaporator 14 surrounds the blower stack 6. When the evaporator 16 works, it will be wetted under the action of the water supply component, resulting in the noise generated by the blower stack 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 blower stack 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.

[0033] 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 the water sink 11. A preset distance is left between the housing side wall 102 and the evaporator 14. 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.

[0034] See Figures 2 to 4 , in order to prevent water from flowing out of the through hole 16, a positioning convex portion 18 is provided with a water blocking wall 17 extending upward around the through hole 16 and surrounding the outer periphery of the bottom of the wind hood 61.

[0035] See Figures 2 to 4 , a positioning groove 33 recessed upward is provided at the bottom of the upper cover 3 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 protrudes upward from the upper water tank 31, and an upper protrusion 34 protruding upward is formed at the bottom of the upper water tank 31. A bottom edge 22 is provided at the bottom of the water tank 2 corresponding to the upper protrusion 34. The bottom edge 22 presses against the upper side of the upper protrusion 34, thereby supporting the water tank 2. In a specific embodiment, the ratio of the bottom area of the through hole 16 to the water sink 11 is less than or equal to 1:2, and the ratio of the volume of the upper protrusion 34 to the upper water tank 31 is less than or equal to 1:2. The limitation of the above parameters can ensure that the evaporator 14 has enough liquid for humidification and guarantee the humidification effect.

[0036] See Figure 2and Figure 4 At the bottom of the water tank 2, there is an installation seat 24 that inserts into the edge of the upper water tank 31. The installation seat 24 can limit the position of the water tank 2. The water outlet valve 21 is located radially inside the installation seat 24. On the side of the upper convex part 34, there is a reinforcing rib 35 connected to the upper cover 3. The installation seat 24 is provided with a notch 23 that is engaged with the reinforcing rib 35. Thus, the position of the water tank 2 is further positioned, and the strength of the structure of the upper cover 3 can be improved.

[0037] 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 blower stack 6 on the base 5, and integrating the components that will come into contact with water, such as the upper water tank 31, the lower water tank 11, and the evaporator 14, 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 for direct flushing or soaking and other 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 inside the air duct 13, the evaporator 14, etc. 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, passes through the blower stack 6, then blows towards the evaporator 14 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.

[0038] Moreover, the structure of this humidifier is more compact, optimizing the volume of the product. Among 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 assembled humidifier product. In this patent, through the combination of the upper cover 3 and the housing 1, the air duct 13 is formed. The blower stack 6 is arranged on the base 5, and the detachable combination of the base 5 and the housing 1 is used to enable the blower stack 6 to enter and exit the air duct 13. At the same time, a positioning groove 33 for fixing the blower stack 6 is provided at the bottom of the upper cover 3 to realize the limitation of the blower stack 6. In addition, a lower water tank 11 and an upper water tank 31 are respectively provided at the bottom of the housing 1 and 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 as to form a downward water flow 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.

[0039] 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 fan stack 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 fan stack 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.

[0040] According to the disclosure and teachings of the above specification, those skilled in the art to which the present utility model pertains 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.
