Description

Technical Field

[0001] The utility model belongs to the technical field of humidifiers, and particularly relates to a humidifying filter element and a humidifier. Background Art

[0002] A filter element for humidification is provided in a humidifier. When the humidifier enters the humidification working state, the humidifying filter element needs to be kept moist, so the humidifying filter element needs to be frequently watered. Generally, the filter screen of the existing humidifying filter element directly abuts against the water outlet hole for humidification, and water droplets directly drip into the humidifying filter element through the water outlet hole to make it moist. If the water flow for humidification contains dirt such as hair, it is easy to cause the water outlet area of the water outlet hole to shrink. After long-term use, the dirt may even block the water outlet hole, resulting in the lack of water in the humidifying filter element and the humidifier losing its humidifying function.

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] Please refer to Figure 1 , Figure 2 and Figure 3 as shown. A preferred embodiment of the humidifying filter element of the present utility model includes a filter element support 1 and filter cotton 2 arranged on the outer side surface of the filter element support 1.

[0018] The filter element support 1 includes a top cover 3, a water distribution tray 4 with a water collection chamber A, a wire mesh frame 5, and a water delivery pipe 6. The top cover 3 covers the upper part of the water distribution tray 4, the water distribution tray 4 is buckled on the upper part of the wire mesh frame 5, and the filter cotton 2 is sleeved on the outer side surface of the wire mesh frame 5. A plurality of water outlet holes 7 are arranged on the bottom surface of the water collection chamber A, and the filter cotton 2 is located directly below the water outlet holes 7. One end of the water delivery pipe 6 communicates with the bottom surface of the wire mesh frame 5, and the other end thereof communicates with the water collection chamber A of the water distribution tray 4.

[0019] Anti-blocking convex ribs 8 are arranged on the side edges of the bottom surface of the water outlet holes 7, and the convex ribs 8 are located on one side edge or both side edges of each water outlet hole 7. The convex ribs 8 abut against the filter cotton 2 so that an anti-blocking gap is left between the water outlet holes 7 and the filter cotton 2.

[0020] Two convex rib rings 81 composed of the convex ribs 8 are arranged on the bottom surface of the water distribution tray 4, and the two convex rib rings 81 are respectively located on the side edges of each water outlet hole 7.

[0021] The protruding height of the convex ribs 8 is 0.5 mm to 2.5 mm. The protruding height of the convex ribs 8 is set according to the anti-blocking requirement of the water outlet holes 7.

[0022] An overflow hole 9 is arranged in the water collection chamber 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, and a water passing notch 92 is arranged on one side of the overflow baffle 91. The height of the water passing notch 92 is lower than the height of the water collection chamber A. The excess accumulated water in the water collection chamber A overflows through the water passing notch 92 and then flows into the filter cotton 2, preventing the excess accumulated water from flowing to other parts of the humidifying filter element. When some of the water outlet holes 7 are blocked, the excess accumulated water can also flow into the filter cotton 2 through the water passing notch 92.

[0023] A plurality of buckling holes 41 are arranged on the water distribution tray 4, and buckling positions 51 corresponding to the buckling holes 41 are arranged on the wire mesh frame 5. The buckling positions 51 are buckled and connected with the corresponding buckling holes 41 so that the water distribution tray 4 is buckled on the upper part of the wire mesh frame 5.

[0024] Please also refer to Figure 2 and Figure 4 As shown, a sleeve 61 is sleeved on the top of the water delivery pipe 6, a baffle 62 is arranged on the top of the sleeve 61, and a water outlet 63 is arranged on the side surface of the baffle 62. The water outlet 63 is respectively communicated with the water delivery pipe 6 and the water collection chamber A. The sleeve 61 is sleeved in a through hole 42 on the water distribution tray 4. The incoming water from the water delivery pipe 6 is blocked by the baffle 62 and then is split by the water outlet 63 and flows into the water collection chamber A, reducing the noise generated after the incoming water directly impacts the top cover 3.

[0025] The present utility model also discloses a humidifier (not shown in the figure), and the humidifying filter element as described above is used in the humidifier.

[0026] Because the humidifying filter element of the present utility model is provided with an anti-blocking structure, the water outlet holes are not easily blocked, effectively preventing the problem of water shortage of the humidifying filter element caused by the blockage of the water outlet holes. The humidifier is not prone to the problem of water shortage of the humidifying filter element, and the stability of its humidifying function is improved.

[0027] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
