Description

Technical Field

[0001] This invention relates to the field of humidifier technology, specifically to air purification and mist-free humidifiers. Background Technology

[0002] A humidifier is a household appliance that increases the humidity in a room. Humidifiers can humidify a specific room or be connected to a boiler or central air conditioning system to humidify an entire building. With economic development and improved living standards, people have increasingly higher demands for quality of life and health. This is how air humidifiers have gradually entered many homes around the world, becoming an indispensable small appliance for families in dry areas.

[0003] Currently, in the industry, non-fogging humidification solutions include fan-type and water pump-type. Chinese invention patent CN115264702A discloses a non-fogging humidifier, including a body assembly, a water tank, and a wet curtain assembly. The body assembly and water tank are spaced vertically, with a ring-shaped air outlet area between them. The wet curtain assembly is located within this ring-shaped air outlet area. The body assembly includes at least a casing with openings at both the top and bottom. The lower end of the casing communicates with the interior of the wet curtain assembly. A fan assembly is located inside the wet curtain assembly. A water inlet shroud is located on the upper part of the casing, containing a water inlet chamber. A ring-shaped air intake area is formed between the wall and the inner wall of the casing, and the ring-shaped air intake area connects downward to the interior of the wet curtain assembly. This patent uses a combination of wet curtain and fan. The wet curtain pre-humidifies the air flowing through the fan's air intake channel, and then the fan sends the humidifier out to achieve the effect of humidifying the air. In addition, this patent places the water tank under the wet curtain. Water in the water tank is sprayed onto the wet curtain through a pipe assembly to humidify the wet curtain. Excess water on the wet curtain drips onto the fixed plate under the action of gravity, and the excess water flows back to the water tank through the inclined guide part from the recessed flow channel to achieve water recycling and reuse.

[0004] The aforementioned mist-free humidifier has a simple water filling method and adopts an upward air outlet scheme; however, it humidifies the air before it enters the air duct system. The humidified air is more corrosive to the air duct components, and its internal circuitry is more prone to damage, greatly reducing its service life. On the other hand, during the use of the humidifier, the wet curtain is kept moist and needs to be replaced as needed. In the aforementioned mist-free humidifier, the wet curtain is fixed in the middle of the overall structure with clips. When replacing the wet curtain, the entire upper structure needs to be disassembled, making the replacement process complex and cumbersome. Summary of the Invention

[0005] This invention provides an air purifier and a mist-free humidifier, aiming to solve the problems of existing mist-free humidifiers, such as the wet curtain being located on the lower side of the structure, the humidification method affecting the service life, and the complicated process of replacing parts.

[0006] The technical solution adopted by this invention to solve its technical problem is: an air purifier and mist-free humidifier, including a main body, a water tank, a wet curtain mechanism, and an air outlet mechanism fixedly connected to the main body. The water tank is fixedly connected to the main body. The main body has a mounting cavity on its upper surface. The wet curtain mechanism includes a wet curtain and a spray mechanism. The wet curtain is distributed in a ring on the upper side of the inner wall of the mounting cavity. The axis of the wet curtain is vertically set. A water recovery tank is fixedly provided on the main body below the wet curtain. The opening of the water recovery tank is upward and connected to the water tank. The water inlet of the spray mechanism is connected to the water tank, and the water outlet is fixedly connected to the main body and located above the wet curtain. The air outlet mechanism is located below the wet curtain and exits the air upward through the wet curtain.

[0007] To solve the connection problem between the water recovery tank and the water tank, the water tank is located inside the wet curtain, and a water storage tank is provided below the water tank. The water tank is fixedly connected above the water storage tank and communicates with the water storage tank. The water inlet of the spray mechanism is connected to the water storage tank. An annular air duct is left between the outer side of the water storage tank and the inner side of the water recovery tank. The air outlet mechanism sends air to the lower end of the wet curtain through the annular air duct. The water storage tank and the water recovery tank are fixedly connected by a connecting rib. A water trough is opened on the connecting rib, and the water trough connects the water recovery tank and the water storage tank.

[0008] To solve the water level control problem of the water tank and storage tank mentioned above, the water tank is equipped with a level controller. The level controller is equipped with a level detector, a valve and a connecting pipe. The inlet end of the connecting pipe is connected to the water tank and the outlet end is connected to the storage tank. The valve is located on the connecting pipe. The level detector collects the water level information of the storage tank and transmits the information to the valve, so that the control valve has two states: closed and open.

[0009] Furthermore, the level controller is a float switch mechanism, which includes a float, a float lever, a push rod, and a sealing ring. The float is located inside the water tank, and the float lever is rotatably connected to the lower end face of the water tank. One end of the float lever is connected to the float, and the other end is connected to the push rod. A through hole is opened on the bottom surface of the water tank, connecting the water tank and the water tank. The push rod is slidably connected to the through hole, and the sealing ring is fixed to the upper side of the outer circumference of the push rod. The float has two states: upper and lower. When the float is in the lower state, the float pushes the push rod with the help of the float lever, and the sealing ring moves upward to clear the through hole, connecting the water tank to the water tank through the through hole. When the float is in the upper state, the float lowers the push rod with the help of the float lever, and the sealing ring moves downward to block the through hole, separating the water tank from the water tank.

[0010] To solve the problem of simultaneous spraying from the evaporative cooling pad, the spraying mechanism includes a water pump, a spraying component, and a water supply pipe. The spraying component is circular and has multiple water outlets. The water outlets are located on the upper side of the evaporative cooling pad and are separated from it by a gap. The spraying component is connected to the main body. The water pump inlet is connected to the water storage tank, the water supply pipe inlet is connected to the water pump outlet, and the water supply pipe outlet is connected to the spraying component.

[0011] To address the issue of which fixing method to use for the aforementioned spraying mechanism, one of the water tank and the spraying mechanism is provided with a rotating snap-fit ​​groove, and the other is provided with a snap-fit ​​protrusion. The spraying mechanism is snapped and fixed to the rotating snap-fit ​​groove.

[0012] To solve the problem of adding water to the water tank of the present invention, the water tank includes a tank body and a tank cover. The axial cross-section of the tank cover is arc-shaped, and the outer diameter of the tank cover is smaller than the inner diameter of the tank body. A fixing block is fixedly provided on the outer circumferential surface of the tank cover. The tank cover is fixedly connected to the tank body through the fixing block and is coaxial.

[0013] To address the issues of air source and installation location in this invention, the air outlet mechanism includes a fan blade and a drive component. The drive component is located below the wet curtain mechanism. The fixed end of the drive component is fixedly connected to the main body, and the movable end of the drive component is connected to the fan blade. The main body has an air inlet on its outer peripheral surface, which is located below the fan blade.

[0014] To address the air purification issue entering the aforementioned air outlet mechanism, an air filter is installed inside the air inlet of the mounting cavity.

[0015] To address the aforementioned air filter protection issues, the main body features a filter housing at the air inlet, with the air filter located inside the filter housing.

[0016] To address the issue of how to facilitate the inspection of the aforementioned air filter, the filter housing is provided with a slit and a side-opening baffle. The side-opening baffle is rotatably connected to the filter housing, and covers the slit when closed.

[0017] Furthermore, the water tank has a chamfered air guide on its bottom surface.

[0018] The beneficial effects of this invention are as follows: The air purifier and mist-free humidifier places the wet curtain on the upper side of the installation cavity, allowing excess water on the wet curtain to collect in the water recovery tank under gravity. The connection between the water recovery tank and the water tank allows for the reuse of excess water, and no additional drive components are needed between the water recovery tank and the water tank. The air outlet mechanism of this invention is located below the wet curtain, forming an upward airflow path. This places the humidifying wet curtain at the rear end of the airflow path, preventing the humidified air from passing through the air outlet mechanism and thus avoiding erosion of its structure by the humidified air. The water tank is located on the upper side of the installation cavity, facilitating water addition by the user. A chamfered guide is provided on the bottom surface of the water tank, tilting the air blowing from the annular air duct and reducing flow resistance as the air flows towards the wet curtain.

[0032] The present invention will be further described below with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0033] Combination Figure 1-5 As shown, the air purifier and mist-free humidifier of the present invention includes a main body 10, a water tank 22, a wet curtain mechanism 20, and an air outlet mechanism 30 fixedly connected to the main body 10. The water tank 22 is fixedly connected to the main body 10. The main body 10 has an upper cavity. The wet curtain mechanism 20 includes a wet curtain 21 and a spray mechanism. The wet curtain 21 is arranged in a ring on the upper side of the inner wall of the cavity, with its axis vertically oriented. A water recovery tank 11 is fixedly provided below the wet curtain 21 on the main body 10. The water recovery tank 11 opens upwards and is connected to the water tank 22. The water inlet of the spray mechanism is connected to the water tank 22, and its outlet is fixedly connected to the main body 10 and located above the wet curtain 21. The air outlet mechanism 30 is located below the wet curtain 21 and exits upwards through the wet curtain 21. The air purifier and mist-free humidifier positions the wet curtain 21 above the cavity, and the water outlet of the spray mechanism is located above the wet curtain. Above 21, after the wet curtain 21 is sprayed and humidified, the excess water on the wet curtain 21 is collected into the water recovery tank 11 under the action of gravity. Through the connection between the water recovery tank 11 and the water tank 22, the excess water can be reused. Moreover, no other driving components need to be added between the water recovery tank 11 and the water tank 22. The water recovery tank 11 and the water tank 22 are connected by their own structure. In the existing water recovery methods, a pump is added between the water recovery structure and the water tank 22 to recover the water into the water tank 22. The air outlet mechanism 30 of the present invention is located below the wet curtain 21, forming an air path from bottom to top. The humidified wet curtain 21 is placed at the rear end of the air path. The air first enters the air outlet mechanism 30 and then is blown out by the air outlet mechanism 30. The air drawn in by the air outlet mechanism 30 has not been humidified, and the air humidity is lower than that of the humidified air, which reduces the degree of air erosion of the air outlet mechanism 30.

[0034] Combination Figure 3 , Figure 4As shown, the water tank 22 of the air purifier and mist-free humidifier of the present invention is located inside the wet curtain 21. A water storage tank 13 is provided below the water tank 22. The water tank 22 is fixedly connected above the water storage tank 13 and communicates with the water storage tank 13. The water inlet of the spray mechanism is connected to the water storage tank 13. An annular air duct 14 is left between the outer side of the water storage tank 13 and the inner side of the water recovery tank 11. The air outlet mechanism 30 sends air to the lower end face of the wet curtain 21 through the annular air duct 14. The water storage tank 13 and the water recovery tank 11 are fixedly connected by a connecting rib 12, on which a water groove is opened. The water tank connects the water recovery tank 11 and the water storage tank 13; the water tank 22 and the water recovery tank 11 are connected through the water storage tank 13, and then the spraying mechanism takes in water from the water storage tank 13. The water tank 22 is connected to the water storage tank 13, and the water in the water recovery tank 11 and the water tank 22 are both used by the spraying mechanism after passing through the water storage tank 13, so that the water in the water recovery tank 11 and the water tank 22 can be used. At the same time, there is a gap between the outer side of the water storage tank 13 and the inner side of the water recovery tank 11. This gap is an annular air duct 14, which makes the air duct in the overall structure unobstructed.

[0035] Combination Figure 4 , Figure 5 As shown, the water tank 22 has a guide chamfer on its bottom surface. The guide chamfer causes the air blown from the annular air duct 14 to tilt, reducing the flow resistance when the air flows towards the wet curtain 21.

[0036] Furthermore, the water tank 22 is equipped with a level controller, which includes a level detector, a valve, and a connecting pipe. The inlet end of the connecting pipe is connected to the water tank 22, and the outlet end is connected to the water storage tank 13. The valve is located on the connecting pipe. The level detector collects the level information of the water storage tank 13 and transmits the information to the valve, enabling the valve to have both closed and open states. The water tank 22 is connected to the water storage tank 13 through the level controller, and the connection status between the water tank 22 and the water storage tank 13 is determined by the liquid level in the water storage tank 13.

[0037] Combination Figure 2 , Figure 4 , Figure 9 , Figure 10As shown, the present invention provides a liquid level controller for air purification and mist-free humidification. The liquid level controller is a float switch mechanism 23, which includes a float 232, a float lever 231, a push rod 233, and a sealing ring 234. The float 232 is disposed in the water storage tank 13. The float lever 231 is rotatably connected to the lower end face of the water tank 22. One end of the float lever 231 is connected to the float 232, and the other end is connected to the push rod 233. A through hole is opened on the bottom surface of the water tank 22, connecting the water storage tank 13 and the water tank 22. The push rod 233 is slidably connected to the through hole. The sealing ring 234 is fixed to the upper side of the outer peripheral surface of the push rod 233. The float 232 has two states: upper and lower. When float 232 is in the lower position, float 232 lifts the top rod 233 with the help of float lever 231, and sealing ring 234 moves upward to clear the through hole, and water tank 13 is connected to water tank 22 through the through hole; when float 232 is in the upper position, float 232 lowers the top rod 233 with the help of float lever 231, and sealing ring 234 moves downward to block the through hole, and water tank 13 is separated from water tank 22; the state of water tank 22 and water tank 13 is realized by float switch mechanism 23. Float switch mechanism 23 has the advantages of simple structure, convenient use, and safety and reliability. Compared with mechanical structure, it has a faster response speed and longer service life. Compared with electronic switch, it has stronger load resistance and impact resistance.

[0038] Combination Figure 2 , Figure 4 , Figure 11 , Figure 12 As shown, the spray mechanism for air purification and mist-free humidification of the present invention includes a water pump 24, a spray element 25, and a water supply pipe. The spray element 25 is annular and has multiple water outlets. The water outlets are located on the upper side of the wet curtain 21 and are separated from the wet curtain 21. The spray element 25 is connected to the main body 10. The water inlet of the water pump 24 is connected to the water storage tank 13, the water inlet of the water supply pipe is connected to the water outlet of the water pump 24, and the water outlet of the water supply pipe is connected to the spray element 25. The spray mechanism transports water located below the upper surface of the wet curtain 21 to the upper side of the upper surface of the wet curtain 21, and then sprays the water onto the wet curtain 21 through the spray element 25.

[0039] Furthermore, the water tank 22 and the spraying mechanism are respectively provided with a rotating snap-fit ​​groove and a snap-fit ​​protrusion. The spraying mechanism is snapped and fixed to the rotating snap-fit ​​groove. The water tank 22 and the spraying mechanism are fixedly connected together by snap-fit. When the wet curtain 21 is replaced in the future, the snap-fit ​​structure is easier to disassemble, which is convenient for disassembly while ensuring the reliability of fixation.

[0040] Depend on Figure 5 , Figure 8As shown, the water tank 22 includes a tank body 221 and a tank cover 222. The axial cross-section of the tank cover 222 is arc-shaped. The outer diameter of the tank cover 222 is smaller than the inner diameter of the tank body 221. A fixing block is fixedly provided on the outer circumference of the tank cover 222. The tank cover 222 is fixedly connected to the tank body 221 through the fixing block and is coaxial. A threaded hole is opened at the top of the tank body 221. A support column is provided on the bottom end face of the tank body 221. A support pile is provided in the water storage tank 13. An annular protrusion is provided on the upper end face of the support pile. The support pile is inserted into the annular protrusion, thereby realizing the fixed cooperation between the water storage tank 13 and the support pile. A fixing block is fixedly provided on the outer circumference of the tank cover 222. The fixed block has two threaded holes, and the first threaded hole and the second threaded hole are fixedly connected by screws. In addition, the outer diameter of the cover 222 is smaller than the inner diameter of the body 221. After the cover 222 and the body 221 are combined to form the water tank 22, a gap is maintained between the edge of the cover 222 and the inner wall of the body 221. When the water tank 22 needs to be filled with water, water is poured onto the cover 222. Because the cover 222 is arc-shaped, the lowest point of the arc is closest to the inner wall of the body 221. Therefore, the water on the cover 222 flows to the surroundings under the action of gravity and flows into the body 221, so the water tank 22 realizes the function of filling water from the top.

[0041] In this invention, the combination of the tank body 221 and the tank cover 222 enables the water tank 22 to have the function of adding water from the top. At the same time, the water adding method of this invention is to add water from the edge of the tank cover 222 downwards, so there is no need to open a water inlet on the upper surface of the tank cover 222, thereby improving the aesthetics of this invention.

[0042] Furthermore, a control system is fixedly installed on the top of the lid 222. The control system includes a display screen, control buttons, and a control circuit board. Connectors are provided on the edge of the lid 222. Figure 6 As shown, an upper power terminal 223 is fixedly provided on the lower end face of the connector, extending downward from the lower end face of the connector. A lower power terminal 224 is fixedly provided on the upper end face of the housing 221. When the housing cover 222 is fixedly connected to the housing 221, the upper power terminal 223 and the lower power terminal 224 come into contact, thereby realizing a power path. Through the upper power terminal 223 and the lower power terminal 224 located on the housing 221 and the housing cover 222, a current path is formed between the two during installation, making them easier to separate during disassembly. Unlike using a wire connection, when using a wire connection, the housing cover 222 cannot be freely placed when cleaning the inside of the housing 221 by removing the housing cover 222, due to the limitation of the power line, making the cleaning method of the housing 221 complicated and difficult.

[0043] Depend on Figure 11As shown, the spray component 25 includes a spray water outlet ring 251 and a spray water outlet bracket 252. The spray water outlet bracket 252 is snapped and fixed to the water tank 22. The lower end face of the spray water outlet bracket 252 is provided with a water inlet. The spray water outlet ring 251 is provided with a water inlet channel and a water outlet. The spray water outlet bracket 252 is snapped and fixed to the spray water outlet ring 251. The water outlet is located above the wet curtain 21. The spray water outlet bracket 252 and the spray water outlet ring 251 are snapped and fixed. When replacing the wet curtain 21, the wet curtain 21 can be exposed simply by removing the spray water outlet ring 251 from the spray water outlet bracket 252.

[0044] Furthermore, the spray outlet bracket 252 and the spray outlet ring 251 are connected through coaxial holes of equal diameter. A one-way valve is provided inside the hole. The one-way valve makes the water flow from bottom to top, so as to prevent water from being drawn from the spray element 25 due to the pressure reduction of the water pump 24.

[0045] Combination Figure 2 , Figure 4 , Figure 5 , Figure 7 As shown, the air outlet mechanism 30 of the present invention for air purification and mist-free humidification includes a fan blade 32 and a drive component 31. The drive component 31 is located below the wet curtain mechanism 20. The fixed end of the drive component 31 is fixedly connected to the main body 10, and the movable end of the drive component 31 is connected to the fan blade 32. The main body 10 has an air inlet on its outer peripheral surface, which is located below the fan blade 32. The air outlet mechanism 30 of the present invention is located below the wet curtain 21, forming an air path from bottom to top. This allows the humidifying wet curtain 21 to be placed at the rear end of the air path, and the humidified air no longer passes through the air outlet mechanism 30, thus avoiding the humid air from eroding the structure of the air outlet mechanism 30.

[0046] Furthermore, the drive component 31 of the aforementioned air outlet mechanism 30 is preferably a motor.

[0047] Furthermore, the fan blades 32 of the aforementioned air outlet mechanism 30 are preferably vortex fan blades 32; compared with traditional fan blades 32, vortex fan blades 32 can output a larger air volume with a smaller space occupation, thereby improving wind power.

[0048] Depend on Figure 5 , Figure 7 As shown, the mounting cavity is equipped with an air filter 33 inside the air inlet; by adding an air filter 33 inside the air inlet, the air drawn in by the air outlet mechanism 30 can be filtered to achieve the purpose of air purification.

[0049] Furthermore, the main body 10 has a filter housing 34 at the air inlet, and the air filter 33 is located inside the filter housing 34. The filter housing 34 protects the air filter 33 from damage during use. At the same time, the filter housing 34 has vent holes, which is also a filtration structure that can filter larger impurities and debris.

[0050] Furthermore, by Figure 7 As shown, the filter housing 34 is provided with a cut and a side-opening baffle 35. The side-opening baffle 35 is rotatably connected to the filter housing 34. When closed, the side-opening baffle 35 covers the cut. By providing the side-opening baffle 35 that can be opened and closed on the filter housing 34, it is convenient for users to check the working status of the air filter 33 and observe the operation of the air outlet mechanism 30.

[0051] In this invention, the main body 10 can be a one-piece molded structure, or it can be disassembled into multiple different segment structures and then assembled. The internal structure of each part is adapted to better fit the structure and function of the parts.

[0052] The above embodiments are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
