Description

Technical Field

[0001] The utility model belongs to the technical field of humidifying equipment, and particularly relates to a silent humidifier which is convenient to disassemble and clean. Background Art

[0002] The existing evaporative humidifier, as a common household appliance, plays an important role in improving the humidity of the indoor environment. Such humidifiers generally include core components such as a housing, an evaporator, a water tank, and a blower. In its structural design, the housing often adopts an integrated structure, integrating components such as a water tank, an evaporator, and electrical components. This design simplifies the assembly process, but after long-term use, dirt is likely to accumulate inside the water tank. Due to the closed nature of the housing, it becomes extremely difficult to clean and maintain the water tank and the evaporator. Specifically, the water tank, as a key component for storing and supplying water to the evaporator, is prone to scale, bacteria, and other impurities remaining during the evaporation and humidification process. If these pollutants cannot be cleaned in time, it will not only affect the humidification effect but also may be dispersed into the air with the moisture, posing a potential threat to the indoor air quality and the health of users. At the same time, since the electrical components are also placed inside the housing, frequent disassembly and cleaning also increase the risks of electric shock and damage. Therefore, there is an urgent need for an evaporative humidifier with a more reasonable design and convenient for cleaning and maintenance to solve the cleaning problems in the prior art. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a silent humidifier which is convenient to disassemble and clean.

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

[0005] A silent humidifier which is convenient to disassemble and clean, including a base assembly, a humidifying assembly, and a water tank. The base assembly is configured with an assembly groove with an open upper side. A blowing device is arranged in the assembly groove. The blowing device is configured with an air outlet and an air inlet penetrating through the bottom of the base assembly.

[0006] The humidifying assembly includes a lower water tank assembly and an upper water tank assembly. The upper side of the lower water tank assembly is open. The upper water tank assembly is detachably covered on the upper side of the lower water tank assembly. The lower water tank assembly and the upper water tank assembly enclose a air duct. The upper water tank assembly is provided with an upper water tank located above the air duct. The lower water tank assembly is provided with a lower water tank located below the air duct. A water outlet communicating with the air duct is opened on the side of the lower water tank. An evaporator with its lower end placed in the lower water tank and its upper end covering the outside of the water outlet is arranged inside the air duct in a ring shape. A through hole is opened at the bottom of the lower water tank. The lower end of the lower water tank assembly is detachably inserted into the assembly groove, so that the blowing device extends into the radial inner side of the evaporator through the through hole.

[0007] The water tank is detachably coupled with the humidifying assembly, and is configured with a drain valve. The drain valve can be controllably opened to supply water to the upper water tank, and the water body flows through the evaporator via the water outlet and then enters the lower water tank.

[0008] Compared with the prior art, in the present utility model, the blowing device is integrated on the base assembly, while the components that will come into contact with water, such as the upper water tank, the lower water tank, and the evaporator, are integrated on the humidifying assembly, thereby separating the components that need to be cleaned from the components that do not need to be cleaned. Therefore, the humidifying assembly can be directly detached for direct daily maintenance such as flushing or soaking, without worrying about damage to the electrified components on the base assembly. Coupled with the fact that the upper water tank assembly and the lower water tank assembly of the humidifying assembly are of a detachable separation structure, it is easier to directly clean structures such as the air duct and the evaporator.

[0009] And by arranging the blowing device radially inside the evaporator, the evaporator surrounds the blowing device. When the evaporator operates, it will be wetted under the action of the water supply assembly, 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 humidifying assembly before spreading to the outside of the humidifier. Therefore, the spread of noise is effectively blocked, the sound insulation effect is improved, and the use experience is enhanced.

[0010] Further, a mounting seat is provided on the periphery of the drain valve, and the mounting seat is detachably inserted into the edge of the upper water tank, thereby realizing the positioning and installation of the water tank and preventing the water tank from falling off.

[0011] Further, a water supply assembly is further included. The water supply assembly includes a floating switch provided 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 controllably lifted by the floating switch as the liquid level of the lower water tank drops, so as to open the drain valve. Or, the push rod can be controllably lowered by the floating switch 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 the water discharge of the water tank can be completed without setting a power pump. Therefore, the power pump is omitted, which is not only quieter but also lower in cost.

[0012] 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.

[0013] 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.

[0014] Further, the humidifying component includes a lower water tank component and an upper water tank component. The upper side of the lower water tank component is open, and the upper water tank component is covered on the upper side of the lower water tank component. The lower water tank component and the upper water tank component enclose to form the air duct. The inner bottom of the lower water tank component forms the lower water tank, and the upper end of the upper water tank component forms the upper water tank.

[0015] Further, the fixed seat is fixedly connected to the lower water tank component, or the upper end of the shaft cylinder is fixedly connected to the upper water tank component. The above setting method facilitates the integration of the water supply component on the lower water tank component or the upper water tank component, so it is convenient for installation and disassembly.

[0016] Further, a grille extending towards the bottom of the lower water tank component is provided around the bottom of the upper water tank component, and the evaporator is surrounded by the grille. The setting of the grille facilitates the fixation of the evaporator. Preferably, the evaporator is of an annular structure.

[0017] Further, the lower water tank extends downward to form a positioning convex portion, and the positioning convex portion is detachably inserted into the assembly groove.

[0018] Further, a preset distance is left between the evaporator and the side wall of the lower water tank component. Setting the above distance can prevent noise from being directly transmitted to the outer wall of the lower water tank component.

[0019] Further, the air outlet is provided around the periphery of the blowing device. Several air discharge ports are provided around the periphery of the upper water tank at the upper end of the humidifying component. The combination of the above air discharge ports and the air duct constitutes a simple and straight air outlet channel. Air enters from the bottom air inlet, is discharged into the air duct through the blowing device, and blows towards the evaporator with moisture and goes up all the way, and is blown out from the top air discharge ports. This upward air outlet method from the bottom ensures that the wind blown out by the blowing device can flow through the entire evaporator, ensuring the maximum humidification amount, and the annular air discharge ports can discharge air in a large range.

[0024] The following is a description of a preferred specific embodiment of the present invention with reference to the drawings.

[0025] SeeFigures 1 to 3 , this embodiment provides a silent humidifier that is easy to disassemble and clean, including a humidifying component 100, a base component 5, and a water tank 2. The humidifying component 100 includes a lower water tank component 1 and an upper water tank component 3. The upper side of the lower water tank component 1 is open, and a lower water tank 11 is formed at its bottom. The upper water tank component 3 is covered on the upper end of the lower water tank component 1, and an upper water tank 31 is formed at its upper end. A wind channel 13 is enclosed between the lower water tank component 1 and the upper water tank component 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 provided inside the wind channel 13 in a ring shape. 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 humidifying component 100, and is configured with a water outlet valve 21 facing the upper water tank 31. The humidifying component 100 is also configured with a water supply component for controlling the water output of the water tank 2 to moisten the evaporator 14. The water supply component includes a floating switch 4 provided at the bottom of the lower water tank 11. The floating switch 4 is configured 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 outlet 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 outlet valve 21, thereby closing the water outlet valve 21 to stop the water flow.

[0026] In the present utility model, by placing the water tank 2 above, simultaneously arranging the upper water tank 31 at the upper end of the wind channel 13 and the lower water tank 11 at the lower end, arranging a floating switch 4 that can change with the liquid level in the lower water tank 11, and arranging a push rod 41 linked with the floating switch 4, the push rod 41 extends to the upper water tank 31 to control the water outlet valve 21 of the water tank 2, thereby controlling the water replenishment of the water tank 2 to the upper water tank 31 according to the liquid level situation in the lower water tank 11. The water in the upper water tank 31 flows to the upper end of the evaporator 14 through the side water outlet 15, thereby wetting 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 improved. This mechanical upward water inlet wetting method does not require an additional power pump for spraying the evaporator 14, and can also ensure the humidifying effect, not only with low cost but also with low noise.

[0027] See Figures 2 to 4, a grille 30 is provided around the bottom of the upper water tank assembly 3 and supported on the lower water tank 11. The evaporator 14 is arranged around between the grille 30 and the side wall of the lower water tank assembly 1. The upper water tank assembly 3 is provided with a plurality of air vents 32 located above the evaporator 14 and arranged around the periphery of the upper water tank 31. Specifically, the evaporator 14 is a humidifying curtain, which 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 water tank assembly 3 and the evaporator 14 can be taken out together.

[0028] 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 arranged 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 can movably penetrate upward through the shaft cylinder 432. In a specific setting mode, the fixed seat 431 is fixedly connected to the lower water tank assembly 1, or the upper end of the shaft cylinder 432 is fixedly connected to the upper water tank assembly 3. When the fixed seat 431 is fixedly connected to the lower water tank assembly 1, the floating switch 4 and the push rod 41 are integrated on the lower water tank assembly 1, so it is convenient for the disassembly, installation and cleaning of the upper water tank assembly 3. When the shaft cylinder 432 is connected to the bottom of the upper water tank assembly 3, the floating switch 4 and the push rod 41 are integrated on the upper water tank assembly 3, so it is convenient for the disassembly, installation and cleaning of the lower water tank assembly 1.

[0029] See Figures 1 to 4 , the lower water tank assembly 1 is detachably installed on the base assembly 5. Specifically, the lower water tank 11 is provided with a positioning convex portion 18 extending downward. The base assembly 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 setting the positioning convex portion 18 and the assembly groove 51, the quick positioning installation of the lower water tank assembly 1 can be realized, and the positioning convex portion 18 can improve the assembly stability between the lower water tank assembly 1 and the base assembly 5.

[0030] See Figures 2 to 4, a blowing device 6 for sending air to the air duct 13 is provided on the base assembly 5. The blowing device 6 includes a wind hood 61 provided on the base assembly 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 assembly 5 is provided at its bottom. The water sink assembly 1 is provided with a through hole 16 corresponding to the wind hood 61. When the water sink assembly 1 is installed on the base assembly 5, the blowing device 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 assembly 5 and blows towards 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 water supply assembly, 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 water sink assembly 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 improved. And the upper side of the blowing device is covered by the upper water tank assembly 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.

[0031] See Figures 2 to 4 , the water sink assembly 1 has a water sink assembly bottom wall 101 and a water sink assembly side wall 102 provided on the periphery of the water sink assembly bottom wall 101. The water sink assembly side wall 102 and the bottom shell bottom wall 101 enclose to form the water sink 11. A preset distance is left between the water sink assembly side wall 102 and the evaporator 14. Multiple barriers for blocking the propagation of noise are formed by the water sink assembly side wall 102, the preset distance, the evaporator 14, and the grille 30. Therefore, the noise of the humidifier is effectively controlled.

[0032] 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.

[0033] See Figures 2 to 4 , the bottom of the upper water tank assembly 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 upper 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.

[0034] See Figure 2 and Figure 4, an installation seat 24 inserted into the edge of the upper water tank 31 is provided around the bottom of the water tank 2. The installation seat 24 can limit the position of the water tank 2. The water discharge valve 21 is located radially inside the installation seat 24. A reinforcing rib 35 connected to the upper water tank assembly 3 is provided on the side of the upper convex part 34. The installation seat 24 is provided with a notch 23 for clamping with the reinforcing rib 35. Thus, the position of the water tank 2 is further positioned, and the structural strength of the upper water tank assembly 3 can be improved.

[0035] The evaporation humidifier of the present utility model adopts a split upper water tank assembly 3, a lower water tank assembly 1, a base assembly 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, disassembly and cleaning are more convenient. Specifically, by integrating the blowing device 6 on the base assembly 5, and integrating the components that will contact water, such as the upper water tank 31, the lower water tank 11, and the evaporator 14, on the humidifying assembly 100, the components that need to be cleaned and those that do not need to be cleaned are separated. Therefore, the humidifying assembly 100 can be directly disassembled and directly rinsed or soaked for daily maintenance without worrying about damaging the charged components on the base assembly 5. Coupled with the fact that the upper water tank assembly 3 and the lower water tank assembly 1 of the humidifying assembly 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 outlet and better humidifying effect.

[0036] 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 humidifier product after later assembly. However, in this patent, the upper water tank assembly 3 and the lower water tank assembly 1 are combined to form the air duct 13. The blowing device 6 is arranged on the base assembly 5, and the blowing device 6 enters and exits the air duct 13 by using the detachable combination of the base assembly 5 and the lower water tank assembly 1. At the same time, a positioning groove 33 for fixing the blowing device 6 is provided at the bottom of the upper water tank assembly 3 to realize the limit of the blowing device 6. In addition, a lower water tank 11 and an upper water tank 31 are respectively provided at the bottom of the lower water tank assembly 1 and the upper side of the upper water tank assembly 3, and their functions are associated by using the floating switch 4 and the push rod 41, so that a downward water path 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.

[0037] 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.

[0038] 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.
