Description

Technical Field

[0001] This invention belongs to the field of humidifier technology, specifically referring to a self-cleaning household humidifier. Background Technology

[0002] With the continuous development of the economy and the continuous improvement of people's living standards, most families use humidifiers to increase the humidity of the air in their homes. The requirements for the function and quality of humidifiers are also increasing. Household humidifiers often use ultrasonic humidifiers or evaporative humidifiers. Humidifiers can not only increase the humidity of the air, but also freshen the air and protect people's health.

[0003] In existing technologies, after prolonged use, household humidifiers are prone to accumulating limescale and breeding bacteria, and the sprayed water mist can harm people's health. Furthermore, if the limescale inside the humidifier is not removed in time, it can easily damage the humidifier. In addition, humidifiers with complex structures are difficult to disassemble and clean, which is time-consuming and laborious. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a self-cleaning household humidifier capable of automatically cleaning scale inside the humidifier. It utilizes an ultrasonic generator to produce high-frequency ultrasonic vibrations that generate water mist for humidification, while simultaneously using an evaporator core to absorb water and form a uniform water film for diffusion, thus improving the humidification efficiency of the household humidifier. Furthermore, employing electromagnetic principles, the attraction or separation between an electromagnetic rod and a cleaning magnetic rod causes the cleaning magnetic rod to move away from or closer to the evaporator core. This allows the humidifier filter to assist in air humidification during humidification mode, and the cleaning magnetic rod to clean the evaporator core during cleaning mode. The humidifier has a compact and detachable structure, making it convenient to use.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention provides a self-cleaning household humidifier, including a water storage mechanism, a humidification box at the upper part of the water storage mechanism, a box cover at the upper part of the humidification box, a rotating cleaning mechanism inside the humidification box, an evaporative humidification mechanism at the lower part of the box cover, the evaporative humidification mechanism being disposed inside the humidification box, a magnetic evaporation mechanism slidingly disposed on the rotating cleaning mechanism, the magnetic evaporation mechanism being sleeved on the outside of the evaporative humidification mechanism, and a pull-out sewage discharge mechanism inside the water storage mechanism.

[0006] Furthermore, the water storage mechanism includes a base plate and a water tank, the water tank being located on the upper part of the base plate. The upper wall of the water tank has evenly distributed liquid-permeable holes with rounded edges to facilitate water diffusion. A humidifying chamber is connected to the upper part of the water tank. A sludge-collecting tank is provided on the base plate, and the water tank is connected to the sludge-collecting tank. The rotating cleaning mechanism includes a rotating motor, an upper brush rod, a lower brush rod, and a side wall brush rod. The rotating motor is embedded in the center of the base plate, and its output end has a rotating column that penetrates the center of the upper wall of the water tank. The upper brush rod and the lower brush rod are symmetrically arranged on the outer side wall of the rotating column. The upper brush rod is located on the upper part of the upper wall of the water tank, and the lower brush rod is located on the lower part of the upper wall of the water tank. The bristles of the upper brush rod and the lower brush rod respectively brush the upper and lower surfaces of the upper wall of the water tank. The side wall brush rod is vertically arranged at the end of the upper brush rod away from the rotating column. The bristles of the side wall brush rod brush the inner side wall of the humidification box. The opposite side walls of the symmetrical side wall brush rods are provided with movable slots. The movable slots penetrate the upper end of the side wall brush rods, and the bristles of the side wall brush rods brush the inner side wall of the humidification box.

[0007] Furthermore, the magnetic evaporation mechanism includes a support ring and an electromagnetic rod. The support ring is circular, with both sides slidably disposed within movable slots. The electromagnetic rods are evenly distributed around the circumference of the support ring and are vertically arranged. Guide arc rods are evenly distributed around the inner circumference of the support ring, corresponding to the electromagnetic rods. The center of the arc trajectory of the guide arc rods is located on the central axis of the adjacent electromagnetic rod. A rotating connecting plate is rotatably sleeved at the lower end of the electromagnetic rod. The other end of the rotating connecting plate is slidably disposed within the adjacent guide arc rod. The movable end of the rotating connecting plate rotates around the electromagnetic rod along the arc trajectory of the guide arc rod adjacent to the electromagnetic rod. A cleaning magnetic rod and a fixing rod are vertically disposed at the end of the rotating connecting plate away from the electromagnetic rod. The outer wall of the cleaning magnetic rod has an edge. The fixing rod is disposed on one side of the cleaning magnetic rod. A humidifying filter is sleeved between the electromagnetic rod and the fixing rod on the same rotating connecting plate.

[0008] Preferably, the upper end of the rotating column is provided with an insertion interface, and the lower end side wall of the rotating column is provided with a liquid extraction port, which is located above the sludge receiving tank. The center of the rotating column is provided with a liquid passage pipe, which connects the insertion interface and the liquid extraction port.

[0009] Furthermore, the evaporative humidification mechanism includes a power motor, a first fan, a water pump, a main support pipe, an evaporation core, and a second fan. The power motor is embedded in the lower center of the casing cover. The first fan is located at the output end of the power motor and rotates inside the casing cover. The water pump is located at the lower center of the first fan. The main support pipe is located at the lower center of the water pump and is connected to the suction end of the water pump. The lower end of the main support pipe is inserted into an insertion port. The internal channel of the main support pipe is connected to a liquid passage pipe. The evaporation core is sleeved... On the outside of the main support tube, the evaporation core is located above the support ring. The output end of the water pump is symmetrically provided with humidification pipes, which are inserted into the evaporation core. The second fan is sleeved on the outer wall of the main support tube and is located between the support ring and the upper brush rod. The diameter of the circle formed by the maximum outer edge of the second fan is smaller than the inner diameter of the support ring. The number of guide arc rods corresponds to the number of fan blades of the second fan. The guide arc rods can pass between adjacent fan blades, which facilitates the disassembly of the magnetic evaporation mechanism from one end of the second fan.

[0010] Preferably, the evaporation core is located inside the circumferentially distributed electromagnetic rods, and the end of the guide arc rod away from the electromagnetic rod is located below the outer edge of the evaporation core. When the electromagnetic rod is energized, it generates magnetism. In humidification mode, the magnetic poles of the electromagnetic rod and the cleaning magnetic rod are opposite, and the electromagnetic rod and the cleaning magnetic rod are attracted to each other. The cleaning magnetic rod moves away from the evaporation core, so that the circumferentially distributed humidification filter screens are connected end to end to form a covering water-containing filter screen to assist in air humidification. In cleaning mode, the current flowing through the electromagnetic rod is reversed, and the magnetic poles of the electromagnetic rod and the cleaning magnetic rod are the same. Under the action of magnetic repulsion, the cleaning magnetic rod slides towards the evaporation core along the trajectory of the guide arc rod corresponding to the electromagnetic rod at that point. The edge of the cleaning magnetic rod is pressed and adhered to the outer wall of the evaporation core, thus cleaning the evaporation core.

[0011] Furthermore, an ultrasonic generator is provided inside the base plate, and piezoelectric transducers are symmetrically connected to the output end of the ultrasonic generator. The piezoelectric transducers are located in the sewage tank. A sewage outlet is provided through the base plate on the side of the sewage tank away from the ultrasonic generator. The two ends of the sewage outlet are provided with mounting grooves, and a sealing strip is provided inside the sewage outlet. During use, the ultrasonic generator operates, and the piezoelectric transducer generates high-frequency mechanical vibrations in the water, forming water mist. The motor drives the first fan to rotate, which in turn causes the main support tube to drive the second fan to rotate synchronously on the rotating column. The second fan draws the water mist into the humidification chamber. At the same time, the water pump draws water from the water tank through the internal channels, liquid inlet, and liquid outlet of the main support tube, and injects it into the evaporation core through the humidification pipe. The evaporation core fully absorbs water to form a uniform water film. Excess water seeps out and splashes onto the humidification filter under the rotation of the evaporation core, wetting the filter. The remaining excess water seeps out from the humidification filter and falls back into the water tank. Through the combined action of the first and second fans, air passes through the moistened evaporation core and humidification filter. Water evaporates from the surface of the water film through diffusion and enters the air. The humidified air is then sprayed out through the lid, humidifying the environment. This achieves the technical effect of combining ultrasonic humidification mode and evaporative humidification mode, improving the humidification efficiency of household humidifiers.

[0012] Furthermore, the pull-out sewage discharge mechanism includes a plug, a support frame, a scraper strip, and a return spring. The plug is inserted into the sewage outlet, and a sealing sleeve covers the outer ring of the plug. Plugs are provided at both ends of the plug, and the plugs engage with the mounting slots. The support frame is symmetrically arranged on the inner wall of the sewage tank and is located outside the piezoelectric transducer. A transition column is rotatably provided inside the support frame. The scraper strip is arranged around the water tank and slides on the inner wall of the water tank. A pull rope is connected between the scraper strip and the plug. The pull ropes are symmetrically arranged, pass through the support frame, and are wound around the transition column. The return spring is connected between the support frame and the scraper strip and is sleeved on the outside of the pull rope. After cleaning the humidifier, remove the plug, disconnect the plug from the mounting slot, and let the wastewater flow out through the drain outlet via the sludge collection tank. As you remove the plug, pull the rope out, which in turn pulls the scraper blade downwards. As the scraper blade moves downwards, it scrapes the side wall of the water tank, cleaning the scale on the side wall. After the wastewater has completely flowed out, reinstall the plug into the drain outlet. The sealing sleeve of the plug and the sealing strip of the drain outlet press against each other to seal the drain outlet. Under the elastic action of the return spring, the scraper blade moves upwards to return to its original position.

[0013] Furthermore, the water tank is connected to a water inlet, and a water level pipe is provided on one side of the water inlet. The water level pipe runs through the water tank, and the upper wall of the water level pipe is not higher than the second fan. The water level pipe is made of transparent material, and a float is slidably installed inside the water level pipe.

[0014] Preferably, the box cover has a control panel at its center, humidification ports are evenly distributed around the circumference of the box cover, and a power connection post is provided on one side of the box cover. The power connection post is inserted into the humidification box body, and the box cover and the humidification box body are detachable. Preferably, the control panel uses a PLC controller, and the power supply column, power motor, water pump, electromagnetic rod, rotary motor and ultrasonic generator are electrically connected to the control panel.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The present invention provides a self-cleaning household humidifier that generates water mist through high-frequency ultrasonic vibration generated by an ultrasonic generator, while simultaneously humidifying by absorbing water through an evaporator core to form a uniform water film. Under the combined action of a first fan and a second fan, air passes through the moistened evaporator core and humidifying filter. Water evaporates from the surface of the water film and enters the air through diffusion. The humidified air is then sprayed out through the lid to humidify the environment. This invention achieves the technical effect of combining ultrasonic humidification mode and evaporative humidification mode, improving the humidification efficiency of household humidifiers compared to single humidification methods. 2. Utilizing electromagnetic principles, the electromagnetic rod and the cleaning magnetic rod move towards or away from the evaporator core through the attraction or separation of the electromagnetic rod and the cleaning magnetic rod. In humidification mode, the humidifying filter assists in air humidification. In cleaning mode, the current flowing through the electromagnetic rod reverses, and the cleaning magnetic rod slides along the trajectory of the guide arc rod towards the evaporator core under the action of magnetic repulsion. The edges of the cleaning magnetic rod clean the evaporator core, thus achieving self-cleaning of the evaporator core. At the same time, the rotation of the upper brush rod, lower brush rod, and side wall brush rod cleans the upper and lower surfaces of the water tank, the liquid passage hole, and the inner side wall of the humidification chamber to remove residual scale. 3. This device adopts an assembled structure, which is compact and easy to use. The cover, evaporative humidification mechanism and magnetic evaporation mechanism are easy to disassemble. After self-cleaning, the wastewater can be discharged by simply removing the plug. During the wastewater discharge process, the scale on the side wall of the water tank is cleaned by the scraper strip, ensuring the cleaning effect of the humidifier. Attached Figure Description

[0022] The pull-out sewage discharge mechanism 5 includes a block 43, a support frame 44, and a scraper strip 46. The block 43 is inserted into the sewage outlet 11, and the outer ring of the block 43 is covered with a sealing sleeve. The two ends of the block 43 are provided with plugs, which engage with the mounting groove 12. The support frame 44 is symmetrically arranged on the inner wall of the sewage receiving tank 20 and is located on the outer side of the piezoelectric transducer 15. A transition column 45 is rotatably provided inside the support frame 44. The scraper strip 46 is arranged around the water tank 7 and slides on the inner wall of the water tank 7. A pull rope 47 is connected between the scraper strip 46 and the block 43. The pull rope 47 is symmetrically arranged and passes through the support frame 44 and is wound around the transition column 45. A return spring 48 is connected between the support frame 44 and the scraper strip 46 and is sleeved on the outer side of the pull rope 47.

[0023] The rotating cleaning mechanism 3 includes a rotating motor 25, which is embedded in the center of the base plate 6. The rotating motor 25 is a waterproof motor. A rotating column 21 is located at the output end of the rotating motor 25, penetrating the center of the upper wall of the water tank 7. An insertion interface 23 is located at the upper end of the rotating column 21, and a suction port 22 is located on the lower side wall of the rotating column 21, above the sludge receiving tank 20. A liquid passage pipe 24 is located at the center of the rotating column 21, connecting the insertion interface 23 and the suction port 22. The outer side wall is symmetrically provided with an upper brush rod 26 and a lower brush rod 261. The upper brush rod 26 is located at the upper part of the upper wall of the water tank 7, and the lower brush rod 261 is located at the lower part of the upper wall of the water tank 7. The bristles of the upper brush rod 26 and the lower brush rod 261 respectively brush the upper and lower surfaces of the upper wall of the water tank 7. The end of the upper brush rod 26 away from the rotating column 21 is vertically provided with a side wall brush rod 27. The bristles of the side wall brush rod 27 brush the inner side wall of the humidifying box 2. The opposite side walls of the symmetrical side wall brush rods 27 are provided with movable slots 28, which penetrate the upper end of the side wall brush rods 27.

[0024] The evaporative humidification mechanism 4 includes a power motor 37, which is embedded in the lower center of the cover 49. The output end of the power motor 37 is equipped with a first fan 36, which is rotatably located inside the cover 49. The lower center of the first fan 36 is equipped with a water pump 38, and the lower center of the water pump 38 is equipped with a main support pipe 39. The main support pipe 39 is connected to the suction end of the water pump 38, and the lower end of the main support pipe 39 is inserted into the insertion interface 23. The internal channel of the main support pipe 39 is connected to the liquid passage pipe 24. An evaporation core 40 is sleeved on the outside of the main support pipe 39. The output end of the water pump 38 is symmetrically equipped with a humidification passage pipe 41, which is inserted into the evaporation core 40. A second fan 42 is sleeved on the outer wall of the main support pipe 39, and the upper wall of the water level pipe 9 is not higher than the second fan 42.

[0025] The magnetic evaporation mechanism 19 includes a support ring 29, which is circular in shape. The inner diameter of the support ring 29 is larger than the diameter of the circle formed by the maximum outer edge of the second fan 42. The two sides of the support ring 29 are slidably disposed in the movable slot 28, and the support ring 29 slides up and down within the movable slot 28. The evaporation core 40 is disposed above the support ring 29. The second fan 42 is disposed between the support ring 29 and the upper brush rod 26. Electromagnetic rods 31 are evenly distributed around the circumference of the support ring 29 and are vertically arranged. Electromagnetic rods 31 are evenly distributed around the inner circumference of the support ring 29. A guide arc rod 30 is provided, which is correspondingly arranged with an electromagnetic rod 31. The center of the arc of the guide arc rod 30 is located on the central axis of the adjacent electromagnetic rod 31. A rotating connecting plate 32 is rotatably sleeved at the lower end of the electromagnetic rod 31. The other end of the rotating connecting plate 32 is slidably disposed within the adjacent guide arc rod 30. The movable end of the rotating connecting plate 32 rotates about the electromagnetic rod 31 along the arc of the guide arc rod 30 adjacent to the electromagnetic rod 31. A clear [unclear] is vertically provided on the end of the rotating connecting plate 32 away from the electromagnetic rod 31. The cleaning magnetic rod 34 and the fixing rod 33 are arranged. The outer wall of the cleaning magnetic rod 34 has a ridge. The fixing rod 33 is located on one side of the cleaning magnetic rod 34. A humidifying filter 35 is sleeved between the electromagnetic rod 31 and the fixing rod 33 on the same rotating connecting plate 32. The evaporation core 40 is located inside the circumferentially distributed electromagnetic rods 31. The end of the guide arc rod 30 away from the electromagnetic rod 31 is located below the outer edge of the evaporation core 40. When the electromagnetic rod 31 is energized, it generates magnetism. In humidification mode, the magnetic poles of the electromagnetic rod 31 are different from the magnetic poles of the cleaning magnetic rod 34. The cleaning magnetic rods 34 are attracted to each other and move away from the evaporator core 40, so that the circumferentially distributed humidifying filter screens 35 are connected end to end to form a covering water-containing filter screen to assist in air humidification. In cleaning mode, the current flowing through the electromagnetic rod 31 is reversed, and the magnetic poles of the electromagnetic rod 31 are the same as the magnetic poles of the cleaning magnetic rod 34. Under the action of magnetic repulsion, the cleaning magnetic rod 34 slides towards the evaporator core 40 along the trajectory of the guide arc rod 30 corresponding to the electromagnetic rod 31 at that point. The edge of the cleaning magnetic rod 34 is pressed and adhered to the outer wall of the evaporator core 40, thus cleaning the evaporator core 40.

[0026] The control panel 18 is located in the center of the cover 49. Humidification ports 17 are evenly distributed around the circumference of the cover 49. A power connection post 16 is located on one side of the cover 49 and is inserted into the humidification chamber 2.

[0027] The control panel 18 uses a PLC controller, and the power supply 16, power motor 37, water pump 38, electromagnetic rod 31, rotary motor 25 and ultrasonic generator 14 are electrically connected to the control panel 18.

[0028] Working principle and workflow: In actual use, water is added to the water tank 7 through the water inlet 8. The float 10 floats on the water surface. The position of the float 10 is observed through the water level pipe 9 to determine the amount of water injected. The water flows into the sewage tank 20 and submerges the piezoelectric transducer 15.

[0029] When the humidifier is powered on and in humidification mode, the rotary motor 25 is not working, and the electromagnetic rod 31 is energized and becomes magnetic. At this time, the magnetic poles of the electromagnetic rod 31 and the cleaning magnetic rod 34 are opposite, and the electromagnetic rod 31 and the cleaning magnetic rod 34 are attracted to each other. The cleaning magnetic rod 34 moves away from the evaporator core 40, so that the circumferentially distributed humidifying filter screen 35 is connected end to end to form a covering water-containing filter screen, which assists in air humidification. The ultrasonic generator 14 works, and the piezoelectric transducer 15 generates high-frequency mechanical vibration in the water to form water mist. The power motor 37 starts, driving the first fan 36 to rotate, which in turn causes the main support tube 39 to drive the second fan 42 to rotate synchronously on the rotating column 21. The second fan 42 draws the water mist into the humidification chamber 2 through the liquid passage 13. At the same time, the water pump 38 pumps water through the main support tube 39. Water is drawn from the water tank 7 through the internal channel, liquid inlet 24, and liquid outlet 22, and injected into the evaporation core 40 through the humidification pipe 41. The evaporation core 40 fully absorbs water to form a uniform water film. Excess water seeps out and splashes onto the humidification filter 35 under the rotation of the evaporation core 40, wetting the humidification filter 35. The remaining excess water seeps out from the humidification filter 35 and falls back into the water tank 7 through the liquid inlet 13. Under the combined action of the first fan 36 and the second fan 42, air passes through the moistened evaporation core 40 and humidification filter 35. Water evaporates from the surface of the water film and enters the air through diffusion. The humidified air is sprayed out through the humidification outlet 17 to humidify the environment. This achieves the technical effect of combining ultrasonic humidification mode and evaporative humidification mode, improving the humidification efficiency of household humidifiers.

[0030] When the humidifier needs to self-clean, fill the water tank 7 to the high position of the water level pipe 9, so that the water in the water tank 7 overflows the liquid passage 13. Then, the control panel 18 controls the humidifier to operate in cleaning mode. The power motor 37 does not work, and the rotary motor 25 starts, which in turn drives the rotating column 21 to rotate inside the water tank 7. The rotating column 21 drives the upper brush rod 26, the lower brush rod 261, and the side wall brush rod 27 to rotate. The rotating upper brush rod 26 and the lower brush rod 261 clean the upper and lower surfaces of the upper wall of the water tank 7 respectively, and clean the residual scale in the liquid passage 13, while the side wall brush rod 27 rotates to scrub. Scale on the inner wall of the humidifier 2 is removed. At the same time, the electromagnetic rod 31 is energized and becomes magnetic. The current flowing through the electromagnetic rod 31 is reversed. At this time, the magnetic pole of the electromagnetic rod 31 is the same as the magnetic pole of the cleaning magnetic rod 34. Under the action of magnetic repulsion, the cleaning magnetic rod 34 slides along the trajectory of the guide arc rod 30 corresponding to the electromagnetic rod 31 towards the evaporation core 40. The edge of the cleaning magnetic rod 34 is pressed and adhered to the outer wall of the evaporation core 40. Driven by the side wall brush rod 27, the magnetic evaporation mechanism 19 rotates outside the evaporation core 40, cleaning the evaporation core 40. The scale that is cleaned falls into the water tank 7. Then turn off the power and remove the cover 49 from the humidifier housing 2. Simply pull it out. Separate the power connector 16 from the humidifier housing 2, separate the main support tube 39 from the rotating column 21, and pull the evaporative humidification mechanism 4 out of the humidifier housing 2. At this point, because the diameter of the circle formed by the maximum outer edge of the second fan 42 is smaller than the inner diameter of the support ring 29, and because the number of guide rods 30 corresponds to the number of blades of the second fan 42, if there is interference between the angle between the guide rod 30 and the blades of the second fan 42, pull the second fan 42 and the magnetic evaporation mechanism 19 out of the humidifier housing 2. Then adjust the angle between the guide rod 30 and the blades of the second fan 42 so that the guide rod 30 can pass between adjacent blades, allowing the magnetic evaporation mechanism 19 to be disassembled from one end of the second fan 42. If the angle between the guide rod 30 and the blades of the second fan 42 is just enough to allow the guide rod 30 to pass between adjacent blades... After removing the evaporative humidification mechanism 4, the magnetic evaporative evaporation mechanism 19 can be slid out from the side wall brush rod 27. Then, remove the used humidification filter 35 for cleaning before reuse or replace it with a new one. The humidifier is relatively lightweight and easy to move after removing the cover 49. Then, pull out the block 43, the plug is disconnected from the mounting slot 12, and the sewage flows out from the drain port 11 through the sewage tank 20. While pulling out the block 43, pull the rope. Pull out rope 47 to move scraper 46 downward. As scraper 46 moves downward, it scrapes the side wall of water tank 7 to clean the scale on the side wall of water tank 7. After the sewage has completely flowed out, install block 43 back into drain port 11. The sealing sleeve of block 43 and the sealing strip of drain port 11 press and seal drain port 11. Under the elastic action of return spring 48, scraper 46 moves upward and resets. When using the humidifier again, simply reinstall magnetic evaporation mechanism 19 and tank cover 49.

[0031] It is worth noting that a rotary seal is set at the insertion position of the main support tube 39 and the rotating column 21. When the humidifier is working normally, the inner wall of the water tank 7 is in the working environment of the ultrasonic generator 14, and scale is not easily accumulated under high-frequency vibration.
