DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] Please also refer to Figures 1 to 10 As shown, a preferred embodiment of a humidification component of the utility model. The humidification component comprises: a hollow cylindrical filter element 1, a filter element upper cover 2, a filter element lower cover 12, and a filter element decorative cover 11. The filter element upper cover 2 and the filter element lower cover 12 are respectively arranged at the upper and lower ends of the filter element 1, and the filter element decorative cover 11 is clamped on the upper end of the filter element upper cover 2. A layer of water-distributing cloth 6 is also arranged between the upper end surface of the filter element 1 and the lower end surface of the filter element upper cover 2.

[0027] A water pipe 13 axially passes through the filter element 1, a second water inlet 7 and an overflow port 8 are provided in the filter element upper cover 2, a first water inlet 19 is provided on the filter element lower cover 12, and the upper and lower ends of the water pipe 13 are respectively connected to the second water inlet 7 and the first water inlet 19. The overflow port 8 is arranged away from the second water inlet 7, and the overflow port 8 directly leads to the upper end surface of the filter element 1. Overflow baffles 16 are arranged around the edges of the overflow port 8.

[0028] A water tank 3 for holding water is provided on the upper surface of the filter element upper cover 2, and multiple steps 17 are evenly distributed in the middle of the water tank 3 along the periphery of the filter element upper cover 2, and each step 17 protrudes from the bottom of the water tank 3. A water discharge hole 4 is provided in the middle of each step 17, and a water flow groove 5 is provided on the lower surface of the filter element upper cover 2. Except for the two water discharge holes 4 located on both sides of the second water inlet 7, the bottoms of the other water discharge holes 4 are connected to each other through the water flow groove 5. The water distribution cloth 6 is located directly below the water flow groove 5 and the water discharge hole 4.

[0029] The two steps 17 farthest from the second water inlet 7 have the same height, and the height of the two steps 17 is lower than the height of the remaining steps 17. A retaining rib 10 is provided at the second water inlet 7, and the retaining rib 10 extends to both sides in a plate shape, and separates the two drain holes 4 located on both sides of the second water inlet 7 from the second water inlet 7. The height of the retaining rib 10 is higher than the height of the overflow baffle 16, and the height of the overflow baffle 16 is higher than the height of the steps 17, and the top of the retaining rib 10 abuts against the lower surface of the filter element decorative cover 11.

[0030] The water in the filter cover 2 flows out of the filter cover 2 through the drain hole 4 and enters the water flow groove 5. Under the action of the water distribution cloth 6, the filter 1 is gradually and evenly moistened. At the same time, due to the action of the water flow groove 5, even if one or a small part of the drain hole 4 is blocked by scale, it will not affect the uniformity of the wetting of the filter 1. When the water in the filter cover 2 reaches a certain amount or there is too much water in the filter cover 2, the water will pass over the overflow baffle 16 and flow out of the overflow port 8 to the filter 1.

[0031] The water-distributing cloth 6 is provided with a notch 9 just below the overflow port 8. Water directly penetrates the filter element 1 from the notch 9 without passing through the water-distributing cloth 6. In this way, the problem of increasing the water resistance due to the blockage of the water discharge hole 4 after the filter element 1 is used for a long time is well solved.

[0032] The diameters of the water holes 4 on both sides of the second water inlet 7 and the diameters of the water holes 4 far away from the second water inlet 7 are greater than the diameters of the other water holes 4 .

[0033] The filter element decorative cover 11 is provided with an overflow cover wall 15 extending downward above the overflow port 8 . The overflow cover wall 15 wraps the overflow baffle 16 , and a gap 20 is provided between the overflow cover wall 15 and the outer side wall of the overflow baffle 16 .

[0034] Noise reduction protrusions 18 are provided on both sides of the second water inlet 7. The noise reduction protrusions 18 are strip-shaped and extend to both sides starting from the side edge of the opening of the second water inlet 7. The noise reduction protrusions 18 are located between the retaining ribs 10 and the inner wall of the water tank 3. The thickness of the noise reduction protrusions 18 gradually becomes thinner as they extend. The extension start and end of the noise reduction protrusions 18 are both smoothly transitioned. The height of the noise reduction protrusions 18 is greater than the height of all the steps 17, and the top of the noise reduction protrusions 18 abuts against the lower surface of the filter element decorative cover 11.

[0035] The external water flows into the humidification assembly from the first water inlet 19, and the water flows out from the second water inlet 7 through the water pipe 13. After being blocked by the filter decorative cover, the water can only flow to the two sides of the second water inlet 7 into the water tank 3 of the filter upper cover 2. When the water flows out from the second water inlet 7, the bubbles are punctured by the noise reduction protrusion 18 and the retaining rib 10, and no bubbles are generated. The water flows along the two sides of the noise reduction protrusion 18 from the starting end to the extension end. The thickness of the noise reduction protrusion 18 becomes thinner and thinner, and the end is smoothly transitioned to prevent the water from flowing to the end of the noise reduction protrusion 18. When the water flows to the end of the noise reduction protrusion 18, bubbles are generated due to the intersection of the water on both sides.

[0036] A bend 21 is provided in the middle of the retaining rib 10 toward the center of the second water inlet 7, and the bend 21 is located at the edge of the second water inlet 7. The bend 21 can eliminate bubbles when water flows out of the second water inlet 7.

[0037] like Figure 5 The D area shown includes two steps 17 and corresponding drain holes 4. If the height of the step 17 in the D area can be 1mm, and the height of the step 17 in other areas is 1.5mm. After the water gushes out from the second water inlet 7, it is blocked by the retaining rib 10 and the noise reduction protrusion 18, and is diverted to both sides of the second water inlet 7. The water spreads to both sides from the second water inlet 7, and finally converges at the two drain holes 4 in the area farthest from the second open water port 7. Therefore, the water finally flows into the water trough 5 from the drain holes 4 in the D area. The upper end surface of the drain hole 4 in this area is low from the bottom of the water trough 3, which can make the water in other places of the water trough 3 slightly thicker, thereby forming a relatively thick layer of water, which is easy to flow to the drain holes 4 in the D area.

[0038] like Figure 5The A region shown includes two steps 17 and corresponding drain holes 4, and the B region includes four steps 17 and corresponding drain holes 4. Water enters the water tank 3 from the second water inlet 7, and overflows the adjacent drain holes 4 from both sides of the second water inlet 7 in sequence, and finally overflows the drain holes 4 in the B region. In this process, because of the existence of the retaining rib 10, water cannot enter the drain holes 4 in the A region at the first time. Therefore, the drain holes 4 in the A and B regions are set to have larger diameters, which balances the water volume of each drain hole 4, or balances the time for each drain hole 4 to completely wet the filter element 1.

[0039] The filter element lower cover 12 is evenly distributed with a plurality of water outlet holes 14 , and the excess water passing through the filter element 1 flows out of the humidification component from the water outlet holes 14 .

[0040] Therefore, the humidifying component of the utility model not only has the function of preventing the water hole from being blocked, but also has the characteristic of low water flow noise during humidification.

[0041] The utility model also discloses a humidifier, in which the humidifying component as mentioned above is used.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
