[0015] The present application further provides a humidifier comprising the humidifier water supplementing structure.

[0016] Based on the above technical scheme, the present application can at least produce the following technical effects:

[0017] 1. By arranging the sound attenuation pipe in the water outlet of the water tank, and gradually reducing the cross-sectional area of the exhaust passage in the sound attenuation pipe along the exhaust direction, the air bubbles in the water tank are reduced in size when the air in the water tank passes through the sound attenuation pipe before entering the water tank, so that the water supplementing noise is reduced.

[0018] 2. By arranging the partition plate in the exhaust passage, the exhaust passage is divided into multiple small passages, so that the large air bubbles entering the sound attenuation pipe are divided into multiple small air bubbles, thereby further reducing the water supplementing noise.

[0019] 3. By arranging the groove on the side of the water outlet pipe away from the water outlet, when the water level in the water tank is lowered and water needs to be supplemented from the water tank, the gas enters from the groove on the side of the water outlet pipe, thereby reducing the air inlet speed and further reducing the water supplementing noise.

[0020] 4、Through setting the baffle ring in the sink, the water outlet pipe is inserted in the baffle ring, so that the water storage space is formed between the baffle ring and the water outlet pipe, the water in the water tank is replenished to the water storage space through the silencer pipe, and then is replenished to the sink from the side opening of the water storage space, when the liquid surface in the water storage space submerges the groove on the water outlet pipe, the water tank will not replenish the liquid in the water storage space any more, and the water replenishment speed of the water tank to the water storage space is far greater than the speed of the water in the water storage space flowing to the sink through the side opening, so that the replenishment speed is very slow limited by the size of the side opening of the baffle ring, and the water replenishment noise is greatly reduced;

[0021] 5、Through setting the size of the side opening of the baffle ring to be less than 3% of the circumference of the baffle ring, the speed of the water flowing from the water storage space to the sink is controlled to be slow enough, and since the water consumption speed in the water tank of the humidifier is slow, the water replenishment speed can be reduced to reduce the water replenishment noise;

[0022] 6、Through setting the piston rod in the water outlet, and setting the sealing ring at the bottom of the water outlet, when the water tank is taken out of the sink, the piston rod is sealed due to the gravity;

[0023] 7、Through setting the filter box on one side of the water injection mechanism, and setting the filter material in the filter box, the water entering the water injection mechanism is more clean. BRIEF DESCRIPTION OF DRAWINGS

[0034] The following is a specific embodiment of the present application, and the accompanying drawings are combined to explain the present application. Figures 1-8 The technical solutions of the present application are further described, but the present application is not limited to the following embodiments.

[0035] The humidifier water replenishing structure comprises a water tank 100, a water tank 200 and a sound attenuation pipe 330, the bottom of the water tank 100 is provided with a water outlet 110, the water tank 200 is connected with the bottom of the water tank 100, the sound attenuation pipe 330 is inserted into the water outlet 110, the sound attenuation pipe 330 is provided with an exhaust passage 360, and the cross-sectional area of the exhaust passage 360 allowing gas to flow through gradually decreases along the exhaust direction. The sound attenuation pipe 330 is provided with a water inlet hole 310 and an exhaust hole, water in the water tank 100 enters the sound attenuation pipe 330 from the water inlet hole 310 and is discharged from the water outlet 110, and air in the water tank 200 enters the sound attenuation pipe 330 from the water outlet 110 and is discharged from the exhaust hole 320. The water replenishing passage 350 and the exhaust passage 360 are as shown in Figure 1 By arranging the sound attenuation pipe 330 in the water outlet 110 of the water tank 100, and gradually increasing the cross-sectional area of the exhaust passage 360 in the sound attenuation pipe 330 along the exhaust direction, the air in the water tank 200 is required to pass through the sound attenuation pipe 330 before entering the water tank 100 during the water replenishing process, and the size of the air bubbles is reduced due to the limitation of the size of the exhaust passage 360 of the sound attenuation pipe 330, thereby reducing the water replenishing noise.

[0036] The exhaust passage 360 is provided with a partition plate 340, and the partition plate 340 divides the exhaust passage 360 into a plurality of small passages. In the embodiment, the exhaust passage 360 is provided with a protrusion 330, the cross-sectional area of the protrusion 330 gradually increases along the exhaust direction, and the partition plate 340 is arranged on the protrusion 330. The partition plate 340 is arranged as six pieces, and divides the exhaust passage 360 into six small passages. In other embodiments, the number of the partition plate 340 and the way of dividing the exhaust passage 360 can be adjusted as required. By arranging the partition plate 340 in the exhaust passage 360, the exhaust passage 360 is divided into a plurality of small passages, so that the large air bubbles entering the sound attenuation pipe 330 are divided into a plurality of small air bubbles, thereby further reducing the water replenishing noise.

[0037] The humidifier water replenishing structure further comprises a water outlet pipe 400, the water outlet pipe 400 is sleeved on the water outlet 110, and the water outlet pipe 400 is threadedly connected with the water outlet 110. The side surface of the side of the water outlet pipe 400 away from the water outlet 110 is provided with a groove 410. In the embodiment, the groove 410 is arranged as two, the two grooves 410 are oppositely arranged, and the shape of the groove 410 is arranged as a U shape. By arranging the groove 410 on the side surface of the side of the water outlet pipe 400 away from the water outlet 110, when the water level in the water tank 200 is lowered and water is replenished from the water tank 100, the gas enters from the groove 410 on the side surface of the water outlet pipe 400, the air inlet speed is reduced, and the water replenishing noise is further reduced.

[0038] The water tank 200 is provided with a baffle ring 210, the water outlet pipe 400 is inserted into the baffle ring 210, a water storage space is formed between the baffle ring 210 and the water outlet pipe 400, the side wall of the baffle ring 210 is provided with an opening 211, and the water in the water storage space enters the water tank 200 through the opening 211. By arranging the baffle ring 210 in the water tank 200 and inserting the water outlet pipe 400 into the baffle ring 210, the water storage space is formed between the baffle ring 210 and the water outlet pipe 400, the water in the water tank 100 is replenished into the water storage space through the sound attenuation pipe 330, and then is replenished into the water tank 200 from the side opening 211 of the water storage space. When the liquid level in the water storage space submerges the groove 410 on the water outlet pipe 400, the water tank 100 will not replenish liquid to the water storage space any more, and the speed at which the water tank 100 replenishes water to the water storage space is much greater than the speed at which the water in the water storage space flows to the water tank 200 through the side opening 211. Therefore, the replenishment speed is limited by the size of the side opening 211 of the baffle ring 210 and becomes very slow, which greatly reduces the replenishment noise.

[0039] Preferably, the size of the side opening 211 of the baffle ring 210 is less than 3% of the circumference of the baffle ring 210 and greater than 2% of the circumference. If the size of the side opening 211 is too small, the water outlet speed is too slow or even no water is outletted, and if the size of the side opening 211 is too large, the water outlet speed is too fast and noise is generated. In the embodiment, the size of the side opening 211 of the baffle ring 210 is set to 2.5 mm. By setting the size of the side opening 211 of the baffle ring 210 to be less than 3% of the circumference of the baffle ring 210, the speed at which the water flows from the water storage space to the water tank 200 is controlled to be slow enough. Since the consumption speed of the water in the water tank 200 of the humidifier is very slow, the replenishment speed can be reduced to reduce the replenishment noise.

[0040] The humidifier water replenishment structure further comprises a piston rod 500 and a sealing ring 600, the piston rod 500 is inserted into the water outlet 110 and is arranged below the sound attenuation pipe 330, and the bottom of the water outlet 110 is provided with the sealing ring 600. By arranging the piston rod 500 in the water outlet 110 and arranging the sealing ring 600 at the bottom of the water outlet 110, when the water tank 100 is taken out of the water tank 200, the piston rod 500 will block the water outlet 110 due to gravity.

[0041] The humidifier water supplementing structure further comprises a water injection mechanism 700 and a humidifying filter disc 800 coaxially arranged, and the water injection mechanism 700 and the humidifying filter disc 800 are arranged in the water tank 200; in the embodiment, the water injection mechanism 700 comprises a support part 710, a mounting shaft 720, a first rotating frame 730 and a second rotating frame 740; the support part 710 is arranged at the upper edge of the water tank 200, is two oppositely arranged supports, and is integrally formed with the water tank 200; the support part 710 is provided with the mounting shaft 720; the first rotating frame 730 and the second rotating frame 740 are sleeved on the mounting shaft 720; and the humidifying filter disc 800 is arranged between the first rotating frame 730 and the second rotating frame 740; water in the water tank 200 is injected into the humidifying filter disc 800 through the water injection mechanism 700.

[0042] The water tank 200 is further provided with a filter box 220, the filter box 220 is arranged at one side of the water injection mechanism 700, the filter box 220 is circumferentially provided with strip-shaped through holes, and the filter box 220 is provided with filter material; in the embodiment, the filter material is zeolite, which has the characteristics of large porosity and specific surface area, and has good adsorption performance and selective ion exchange performance, and polar molecules and bacteria are easily enriched on the zeolite; the water quality is purified by arranging the filter box 220 in the water tank 200 and arranging the zeolite in the filter box 220, and the water entering the water injection mechanism 700 is more clean.
