Humidification filter core and humidifierTechnical Field
The utility model belongs to the technical field of humidifiers, and particularly relates to a humidifying filter element and a humidifier.
Background
The humidifier is internally provided with a filter element for humidification, and when the humidifier enters a humidification working state, the humidification filter element needs to be kept moist, so that water needs to be added to the humidification filter element frequently.

Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1, 2 and 3, a preferred embodiment of the humidifying filter element of the present utility model includes a filter element support 1 and a filter cotton 2 disposed on an outer side surface of the filter element support 1.
The filter element support 1 comprises a top cover 3, a water distribution disc 4 with a water collecting cavity A, a net rack 5 and a water delivery pipe 6. The top cover 3 covers the upper part of the water diversion disk 4, the water diversion disk 4 is buckled on the upper part of the net rack 5, and the filter cotton 2 is sleeved on the outer side surface of the net rack 5. A plurality of water draining holes 7 are arranged on the bottom surface of the water collecting cavity A, and the filter cotton 2 is positioned under the water draining holes 7. One end of the water pipe 6 is communicated with the bottom surface of the net rack 5, and the other end is communicated with the water collecting cavity A of the water distributing disc 4.
The side edge of the bottom surface of each water outlet 7 is provided with an anti-blocking convex rib 8, and the convex ribs 8 are positioned on one side edge or two side edges of each water outlet 7. The convex ribs 8 are abutted against the filter cotton 2, so that an anti-blocking gap is reserved between the water drain hole 7 and the filter cotton 2.
Two convex rib rings 81 consisting of convex ribs 8 are arranged on the bottom surface of the water diversion disk 4, and the two convex rib rings 81 are respectively positioned at the side edge of each water drain hole 7.
The protruding height of the protruding ribs 8 is 0.5 mm-2.5 mm. The protruding height of the convex rib 8 is set according to the anti-blocking requirement of the water outlet 7.
An overflow hole 9 is formed in the water collecting cavity A, the overflow hole 9 is located at the top of the filter cotton 2, an overflow baffle 91 is arranged on the upper periphery of the overflow hole 9, a water passing notch 92 is formed in one side of the overflow baffle 91, and the height of the water passing notch 92 is lower than that of the water collecting cavity A. The surplus accumulated water in the water collecting cavity A flows into the filter cotton 2 after overflowing through the water passing notch 92, so that the surplus accumulated water is prevented from flowing to other parts of the humidifying filter element. After some of the water holes 7 are blocked, the excessive accumulated water can also flow into the filter cotton 2 through the water passing notch 92.
The water distribution plate 4 is provided with a plurality of buckling holes 41, the net rack 5 is provided with buckling positions 51 corresponding to the buckling holes 41, and the buckling positions 51 are buckled and connected with the corresponding buckling holes 41 so that the water distribution plate 4 is buckled on the upper portion of the net rack 5.
Referring to fig. 2 and 4, a sleeve 61 is sleeved on the top of the water pipe 6, a baffle 62 is disposed on the top of the sleeve 61, a water outlet 63 is disposed on the side surface of the baffle 62, and the water outlet 63 is respectively communicated with the water pipe 6 and the water collecting cavity a. The sleeve 61 is sleeved in the through hole 42 on the water distribution disk 4. The water entering from the water pipe 6 is blocked by the baffle 62, is split by the water outlet 63 and flows into the water collecting cavity A, so that the noise generated after the water entering directly impacts the top cover 3 is reduced.
The utility model also discloses a humidifier (not shown in the figure), wherein the humidifying filter element is used.
Because the anti-blocking structure is arranged on the humidifying filter element, the water outlet is not easy to block, the problem that the humidifying filter element lacks water due to the blocking of the water outlet is effectively prevented, the problem that the humidifying filter element lacks water is not easy to occur in the humidifier, and the stability of a humidifying function is improved.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
