[0002] A steam humidifier is a device that heats water to generate steam and then releases the steam into the air to regulate ambient humidity and improve dry air. Steam humidifiers have advantages such as fast humidification speed, low bacterial growth, and low water quality requirements, and are widely used in home bedrooms, offices, hospital wards, and industrial clean areas.

[0003] Currently, most noise reduction structures are installed in the top cover. The top cover of traditional steam humidifiers is not easy to install and requires the use of special tools such as screwdrivers to operate on the fasteners one by one, which makes it inconvenient to clean and repair the steam humidifier later. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a noise reduction structure and usage method for an easy-to-install steam humidifier, solving the problem that the top cover of traditional steam humidifiers is inconvenient to install, requiring the use of special tools such as screwdrivers to operate on the fasteners one by one, which makes it inconvenient to clean and maintain the steam humidifier later.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a noise reduction structure for an easy-to-install steam humidifier, comprising a humidifier housing, a mounting ring fixedly connected to the top of the humidifier housing, lower side plates fixedly connected to both sides of the mounting ring, a slot provided inside the lower side plates, a top cover hinged to one side of the mounting ring, upper side plates fixedly connected to both sides of the top cover, mounting plates symmetrically fixedly connected to the top of the upper side plates, support rods fixedly connected to opposite sides of the two mounting plates, sliding blocks symmetrically slidably connected to the outer walls of the support rods, springs fixedly connected to opposite sides of the two sliding blocks, a sliding groove provided inside the upper side plates, the outer walls of the sliding blocks slidably connected to the sliding grooves, a locking block fixedly connected to the bottom of the sliding blocks, the outer walls of the locking blocks being disposed within the locking grooves, and a noise reduction component installed inside the top cover.

[0006] By adopting the above technical solution, after the top cover and the mounting ring are hinged by a pin, the operator only needs to slide the sliding blocks towards each other in the sliding groove. At this time, the spring is compressed, and the two locking blocks move closer to each other. After the top cover is placed on the mounting ring and the locking blocks are in the corresponding positions of the locking groove, the sliding blocks are released. Under the reaction force of the spring, the sliding blocks move away from each other along the support rod, thereby driving the locking blocks to move away from each other and lock into the inside of the locking groove. The installation of the top cover can be completed with simple operation without the need for multiple tools, which greatly saves installation time and improves installation efficiency.

[0012] Preferably, a perforated plate is fixedly connected to the inner wall of the output end of the steam output pipe, and a rotating shaft is fixedly connected to the inner wall of the perforated plate. One end of the rotating shaft is rotatably connected to the steam output pipe, and a circular gear is fixedly connected to the outer wall of one end of the rotating shaft. A brush is fixedly connected to the other end of the rotating shaft. One side of the brush is disposed on one side of the perforated plate. A rack is meshed with the tooth end of the circular gear. The bottom of the rack is fixedly connected to the top of one of the limiting rods. A mounting cover is fixedly connected to the top of the limiting rod. The outer walls of both the rack and the circular gear are disposed within the mounting cover.

[0013] Preferably, a heating base is provided at the bottom of the humidifier housing, a water storage tank is installed at the top of the heating base, a horizontal plate is fixedly connected to the top of the water storage tank, a connecting cover is fixedly connected to the top of the horizontal plate, a second motor is installed inside the connecting cover, a stirring shaft is fixedly connected to the output end of the second motor, and stirring blades are uniformly fixedly connected to the outer wall of the stirring shaft.

[0015] A method for using a noise reduction structure for an easy-to-install steam humidifier includes the following steps: When in use, by pressing the sliding blocks in opposite directions, the sliding blocks slide along the support rod in the groove. When the spring is compressed, the locking blocks move closer to each other. The top cover is closed on the mounting ring, and the locking blocks are aligned with the slots on the lower side plate before being released. When the spring returns to its original position, it moves the sliding blocks away, and the locking blocks are locked into the slots. To disassemble, simply press the sliding block to disengage the locking block from the slot. Steam passes through the steam inlet of the support ring, enters through the steam inlet of the soundproof frame, and passes through the return hole after being blocked by the partition. The soundproof cover and soundproof frame block noise, and the soundproof cotton absorbs sound. Start the drive motor, the rotating shaft drives the drive gear and drive bevel gear to rotate, the drive gear meshes with the driven gear to drive the rotating chamber and steam output pipe to rotate circumferentially, the drive bevel gear drives the meshing driven bevel gear to drive the connecting shaft and cam to rotate, the cam lifts the sliding plate up and down along the limit rod, driving the steam output pipe to adjust vertically; When the steam output pipe is raised or lowered, the circular gear meshes with the rack and pinion to rotate, driving the brush to clean the perforated plate. The heating base heats the water in the storage tank, and the second motor drives the stirring shaft and stirring blades to stir. The stirring shaft drives the drive wheel, which in turn drives the driven wheel and cleaning roller to rotate via a belt, cleaning the inner wall of the storage tank.

[0016] This invention provides a noise reduction structure and usage method for an easy-to-install steam humidifier. It offers the following advantages: 1. In this invention, after the top cover and the mounting ring are hinged by a pin, the operator only needs to slide the sliding blocks towards each other in the sliding groove. At this time, the spring is compressed, and the two locking blocks move closer to each other. After the top cover is placed on the mounting ring and the locking blocks are in the corresponding positions of the locking groove, the sliding blocks are released. Under the reaction force of the spring, the sliding blocks move away from each other along the support rod, thereby driving the locking blocks to move away from each other and lock into the locking groove. The installation of the top cover can be completed with simple operation without the use of multiple tools, which greatly saves installation time and improves installation efficiency.

[0017] 2. In this invention, high-temperature steam generated by the humidifier flows upward, passing sequentially through the steam inlet of the support ring and the steam inlet at the bottom of the soundproof frame before entering the soundproof frame. As the steam flows upward, it is blocked by the baffle and passes laterally through the return hole, forming a zigzag path. This prolongs the contact time with the soundproof structure. During this process, the double wrapping of the soundproof cover and the soundproof frame blocks airflow noise and boiling noise. The sound-absorbing cotton at the bottom of the top cover absorbs and dissipates sound energy through its porous structure. The zigzag effect of the return hole causes the sound waves to continuously attenuate after multiple reflections and refractions. The synergistic effect of multiple soundproofing, sound absorption, and noise reduction structures suppresses noise from multiple angles—the sound source, the propagation path, and the sound wave energy—significantly reducing the overall operating noise of the humidifier.

[0018] 3. In this invention, a drive motor drives a rotating shaft to rotate. The bottom active gear meshes with and drives the driven gear, which in turn drives the rotating cavity, the top limiting rod, the sliding plate, the connecting pipe, and the steam output pipe to perform circular motion, thereby achieving horizontal steam adjustment. Simultaneously, the active bevel gear at the top of the rotating shaft meshes with and drives the driven bevel gear and the connecting shaft to rotate, causing the cam to rotate. The cam's convex end lifts the sliding plate, stretching the second spring. After the convex end rotates away, the sliding plate returns to its original position under the action of the second spring, causing the steam output pipe to rise and fall. This, combined with the bellows, achieves vertical adjustment. The linkage between horizontal and vertical adjustment ensures uniform steam distribution, avoiding concentrated high-speed spray that would produce whistling and secondary noise. When the steam output pipe rises and falls, the circular gear and the rack move relative to each other and rotate, driving the brush to clean the micropores of the perforated plate, preventing blockage and whistling, and reducing noise.

[0019] 4. In this invention, the output end of the second motor drives the stirring shaft and stirring blades to rotate, which forces the water to be stirred so that the water temperature is uniform, avoids local overheating and boiling, and reduces low-frequency noise and resonance noise from bubble bursting. At the same time, the stirring shaft drives the drive wheel to rotate, which drives the driven wheel and cleaning roller to rotate through the belt. The cleaning roller scrapes against the inner wall of the water tank to remove scale, preventing noise and scale friction noise caused by uneven heating, further reducing the noise of the whole machine and ensuring stable noise reduction effect.

Detailed Implementation

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides a noise reduction structure for an easy-to-install steam humidifier, including a humidifier housing 1. A mounting ring 201 is fixedly connected to the top of the humidifier housing 1. Lower side plates 202 are fixedly connected to both sides of the mounting ring 201. A slot 203 is provided inside the lower side plate 202. An upper cover 204 is hinged to one side of the mounting ring 201. Upper side plates 205 are fixedly connected to both sides of the upper cover 204. Mounting plates 206 are symmetrically fixedly connected to the top of the upper side plates 205. Two mounting plates... A support rod 207 is fixedly connected to the opposite side of the mounting plate 206. Sliding blocks 208 are symmetrically slidably connected to the outer wall of the support rod 207. A spring 209 is fixedly connected to the opposite side of the two sliding blocks 208. A groove 210 is opened inside the upper side plate 205. The outer wall of the sliding block 208 is slidably connected in the groove 210. A locking block 211 is fixedly connected to the bottom of the sliding block 208. The outer wall of the locking block 211 is set in the locking groove 203. A noise reduction component is installed inside the upper cover 204.

[0024] Specifically, the upper cover 204 and the mounting ring 201 are hinged to achieve flip-opening and closing. During installation, the operator presses the two sliding blocks 208 towards each other, causing the sliding blocks 208 to slide inward along the support rod 207 within the slide groove 210. At this time, the spring 209 between the two sliding blocks 208 is compressed, and the locking blocks 211 at the bottom of the two sliding blocks 208 move closer to each other. Then, the upper cover 204 is placed on top of the mounting ring 201, aligning the locking blocks 211 with the locking groove 203 in the lower side plate 202. After releasing the sliding blocks 208, the elastic return of the spring 209... When force is applied, the two sliding blocks 208 move away from each other along the support rod 207, thereby causing the locking block 211 to extend outward and lock into the slot 203, achieving quick locking and fixing of the top cover 204 and the mounting ring 201. When disassembling, press the sliding blocks 208 together again to make the locking block 211 exit from the slot 203, and then flip the top cover 204 upward to open. The entire installation and disassembly can be completed by manually pressing the sliding blocks 208. The structure is simple and the operation is convenient, which improves the overall installation and maintenance efficiency of the noise reduction structure and reduces the overall noise of the humidifier when it is working through the noise reduction components.

[0025] Please see the appendix Figure 1 -Appendix Figure 5The noise reduction component includes a connecting ring 3, the top of which is fixedly connected to the bottom of the upper cover 204. A support ring 301 is fixedly connected to the bottom of the connecting ring 3. Steam inlets 302 are evenly distributed inside the support ring 301. A soundproof cover 303 and a soundproof frame 304 are respectively installed at the bottom of the connecting ring 3. A steam inlet 305 is provided at the bottom of the soundproof frame 304. Partitions 306 are fixedly connected to the inner walls on both sides of the soundproof frame 304. A reflux hole 307 is provided inside the partition 306. Soundproof cotton 308 is installed at the bottom of the upper cover 204. A steam outlet 309 is provided inside the upper cover 204.

[0026] Specifically, the high-temperature steam generated by the humidifier flows upward, first passing through the evenly distributed steam inlets 302 on the support ring 301, and then entering the interior of the soundproof frame 304 through the steam inlet 305 at the bottom of the soundproof frame 304. The steam flows upward within the soundproof frame 304, and when it passes the baffle 306, it is blocked and redirected, passing laterally through the return hole 307 inside the baffle 306, forming a zigzag flow path. This prolongs the contact time between the steam and the soundproof structure. During this process, the airflow noise generated by the steam flow is reduced. The humidifier is doubly shielded from boiling noise by the soundproof cover 303 and the soundproof frame 304, preventing noise from radiating outward. The soundproof cotton 308 at the bottom of the top cover 204 uses a porous sound-absorbing structure to absorb and dissipate the incoming sound energy. The return hole 307 continuously changes the direction of sound wave propagation, causing the sound wave to continuously attenuate energy through multiple reflections and refractions. This achieves the cooperation of multiple soundproofing, sound absorption, and noise reduction structures, suppressing noise from multiple angles such as sound source blocking, path dissipation, and sound wave reflection, thereby reducing the overall noise of the humidifier during operation.

[0027] Please see the appendix Figure 6 -Appendix Figure 10 A fixed frame 4 is fixedly connected to the top of the cover 204. A drive motor 401 is installed on the top of the fixed frame 4. A rotating shaft 402 is fixedly connected to the output end of the drive motor 401. A drive gear 403 is fixedly connected to the bottom of the rotating shaft 402. A driven gear 404 is meshed with the tooth end of the drive gear 403. A rotating cavity 405 is fixedly connected to the inner wall of the driven gear 404. The bottom of the rotating cavity 405 is rotatably connected to the top of the cover 204. A connecting pipe 406 is fixedly connected to the top of the rotating cavity 405. The steam outlet 309 of the cover 204 is located inside the rotating cavity 405.

[0028] Limiting rods 5 are uniformly fixedly connected to the top of the rotating cavity 405. A sliding plate 501 is slidably connected to the outer wall of the limiting rods 5. A second spring 502 is uniformly fixedly connected to the bottom of the sliding plate 501. One end of the second spring 502 is fixedly connected to the top of the rotating cavity 405. The inner wall of the second spring 502 is fitted onto the outer wall of the limiting rods 5. A steam output pipe 503 is fixedly connected to the top of the sliding plate 501, and the bottom of the steam output pipe 503 is fixedly connected to the top of the connecting pipe 406. The end of the connecting pipe 406 near the steam output pipe 503 is a corrugated pipe, and the end of the connecting pipe 406 near the rotating cavity 405 is a rigid pipe.

[0029] A driving bevel gear 6 is fixedly connected to the top of the rotating shaft 402. The teeth of the driving bevel gear 6 are meshed with a driven bevel gear 601. A connecting shaft 602 is fixedly connected to the inner wall of the driven bevel gear 601. A support plate 603 is rotatably connected to the outer wall of the connecting shaft 602. One end of the support plate 603 is fixedly connected to the inner wall of the fixed frame 4. A cam 604 is fixedly connected to one end of the connecting shaft 602. When the cam 604 moves, the protruding end contacts the bottom of the sliding plate 501.

[0030] Specifically, when the drive motor 401 is started, its output end drives the rotating shaft 402 to rotate. The drive gear 403 at the bottom of the rotating shaft 402 rotates synchronously. The drive gear 403 meshes with and drives the driven gear 404 to rotate. The driven gear 404 drives the rotating cavity 405 to rotate on the top of the upper cover 204. The rotating cavity 405 then drives the top limit rod 5, sliding plate 501, connecting pipe 406 and steam output pipe 503 to perform circular motion together, realizing 360° horizontal adjustment of the steam output direction. Simultaneously, the driving bevel gear 6 at the top of the rotating shaft 402 rotates synchronously, meshing and driving the driven bevel gear 601 and the connecting shaft 602 to rotate. The connecting shaft 602 drives the cam 604 to rotate continuously. When the protruding end of the cam 604 rotates upward and contacts the bottom of the sliding plate 501, it pushes the sliding plate 501 upward along the limiting rod 5. At this time, the second spring 502 at the bottom of the sliding plate 501 is stretched. When the protruding end of the cam 604 rotates away, under the pulling force of the second spring 502, the sliding plate 501 returns to its original position downward along the limiting rod 5. The sliding plate 501 reciprocates up and down. When in motion, the steam output pipe 503 is raised and lowered synchronously, and the corrugated pipe at the end of the connecting pipe 406 is deformed to achieve vertical adjustment of the steam output angle. Through the linkage of horizontal circumferential adjustment and vertical pitch adjustment, the steam output range is larger and the distribution is more uniform, avoiding the whistling caused by concentrated high-speed steam ejection and reducing the secondary noise generated by airflow impact. The drive motor 401 is a silent DC geared motor, and the drive gear 403 and the driven gear 404 are matched with high-precision involute spur gears, with small meshing clearance and smooth transmission, avoiding abnormal noise caused by gear meshing impact.

[0031] Please see the appendix Figure 6 Appendix Figure 7 Appendix Figure 9A perforated plate 7 is fixedly connected to the inner wall of the output end of the steam output pipe 503. A rotating shaft 703 is fixedly connected to the inner wall of the perforated plate 7. One end of the rotating shaft 703 is rotatably connected inside the steam output pipe 503. A circular gear 702 is fixedly connected to the outer wall of one end of the rotating shaft 703. A brush 704 is fixedly connected to the other end of the rotating shaft 703. One side of the brush 704 is located on one side of the perforated plate 7. A rack 701 is meshed with the tooth end of the circular gear 702. The bottom of the rack 701 is fixedly connected to the top of one of the limiting rods 5. A mounting cover 705 is fixedly connected to the top of the limiting rod 5. The outer walls of the rack 701 and the circular gear 702 are both located inside the mounting cover 705.

[0032] Specifically, when the steam output pipe 503 moves up and down with the sliding plate 501, the circular gear 702 and the rack 701 fixed on the top of the limit rod 5 are relatively displaced. Under the meshing drive of the rack 701, the circular gear 702 rotates around the rotating shaft 703. The circular gear 702 synchronously drives the brush 704 to rotate. The brush surface of the brush 704 is in close contact with the inner surface of the perforated plate 7. As the circular gear 702 continues to rotate, it cleans the micropores on the perforated plate 7, removes impurities and condensed dirt in time, and avoids the blockage of the perforated plate 7, which would cause poor steam flow and sudden increase in local flow velocity, resulting in whistling noise. The mounting cover 705 encloses the rack 701 and the circular gear 702, reducing the impact of external impurities on the circular gear 702 and the rack 701.

[0033] Please see the appendix Figure 6 Appendix Figure 11 Appendix Figure 12 The bottom of the humidifier housing 1 is provided with a heating base 101, the top of the heating base 101 is provided with a water storage tank 8, the top of the water storage tank 8 is fixedly connected with a horizontal plate 801, the top of the horizontal plate 801 is fixedly connected with a connecting cover 802, a second motor 803 is installed inside the connecting cover 802, the output end of the second motor 803 is fixedly connected with a stirring shaft 804, and stirring blades 805 are evenly fixedly connected to the outer wall of the stirring shaft 804.

[0034] A connecting frame 9 is fixedly connected to the top of the stirring shaft 804. A drive wheel 901 is fixedly connected to the top of the stirring shaft 804. A belt 902 is installed on the outer wall of the drive wheel 901. A driven wheel 903 is provided on the inner wall of one end of the belt 902. A cleaning roller 904 is rotatably connected to the inner wall of the driven wheel 903. The top of the cleaning roller 904 is rotatably connected in the connecting frame 9. The outer wall of the cleaning roller 904 is provided on the inner wall of the water storage tank 8.

[0035] Specifically, when the heating base 101 is working, it heats the water in the water storage tank 8, causing the water to boil and generate steam. The second motor 803 is started, and its output end drives the stirring shaft 804 to rotate. The stirring shaft 804 drives the stirring blades 805 on the outer wall to rotate continuously in the water storage tank 8, forcibly stirring the water. This makes the water temperature in the water storage tank 8 quickly and evenly, avoiding local overheating and violent boiling, reducing the low-frequency noise generated by the concentrated bursting of large bubbles, and at the same time weakening the violent vibration when the water boils, reducing the resonance noise caused by the vibration transmitted to the humidifier shell 1. At the same time, the stirring shaft 804 drives the top drive wheel 901 to rotate synchronously. The drive wheel 901 drives the driven wheel 903 to rotate through the belt 902. The driven wheel 903 drives the cleaning roller 904 to rotate within the connecting frame 9. The outer wall of the cleaning roller 904 is in close contact with the inner wall of the water storage tank 8. As the driven wheel 903 continues to rotate, it scrapes and cleans the inner wall of the water storage tank 8, removing scale and dirt adhering to the inner wall in a timely manner. This prevents excessive scale buildup from causing uneven heating, local overheating, and boiling. At the same time, it avoids scale rubbing against the inner wall of the water storage tank 8 and vibrating to generate additional abnormal noise, further reducing the overall operating noise of the machine and improving the stability of the noise reduction effect.

[0036] A method for using a noise reduction structure for an easy-to-install steam humidifier includes the following steps: In use, by pressing the sliding blocks 208 towards each other, the sliding blocks 208 slide along the support rod 207 in the slide groove 210, the spring 209 is compressed, the locking blocks 211 move closer to each other, the upper cover 204 is closed on the mounting ring 201, the locking blocks 211 are aligned with the locking groove 203 of the lower side plate 202 and then released, the spring 209 returns to its original position and drives the sliding blocks 208 away, the locking blocks 211 are locked into the locking groove 203 and fixed. To disassemble, press the sliding block 208 to disengage the locking block 211 from the slot 203. Steam passes through the steam inlet 302 of the support ring 301, enters through the steam inlet 305 of the sound insulation frame 304, and passes through the return hole 307 after being blocked by the partition 306. The sound insulation cover 303 and the sound insulation frame 304 block noise, and the sound insulation cotton 308 absorbs sound. When the drive motor 401 is started, the rotating shaft 402 drives the drive gear 403 and the drive bevel gear 6 to rotate. The drive gear 403 meshes with the driven gear 404 to drive the rotating cavity 405 and the steam output pipe 503 to rotate circumferentially. The drive bevel gear 6 drives the meshing driven bevel gear 601 to drive the connecting shaft 602 and the cam 604 to rotate. The cam 604 lifts the sliding plate 501 and moves it up and down along the limit rod 5, thereby driving the steam output pipe 503 to adjust vertically. When the steam output pipe 503 is raised or lowered, the circular gear 702 meshes with the rack 701 and rotates, driving the brush 704 to clean the perforated plate 7. The heating base 101 heats the water in the water storage tank 8. The second motor 803 drives the stirring shaft 804 and stirring blade 805 to stir. The stirring shaft 804 drives the drive wheel 901, which drives the driven wheel 903 and cleaning roller 904 to rotate through the belt 902 to clean the inner wall of the water storage tank 8.
