Description

Technical Field

[0001] The utility model relates to the technical field of humidifier filter cores, in particular to a filter core structure for a humidifier. Background Art

[0002] With the advancement of science and technology, people's living standards are improving, and their expectations for living environments are gradually increasing. Air humidity is a key factor affecting comfort, especially in northern my country and in places where air conditioning is used regularly. The environment is very dry, and appropriate equipment is needed to increase air humidity and create a comfortable living environment. Therefore, home humidifiers are becoming increasingly popular among families, becoming a must-have appliance in every home.

[0003] At present, in the existing humidifier, a water absorption mechanism is generally provided in the water tank structure, which can effectively absorb the water in the water tank and extract the water vapor under the action of the fan. The water absorption mechanism generally includes a frame and a filter core, and the filter core is sleeved on the outside of the frame. The filter core in the prior art (such as Figure 1 (as shown) is a cylindrical unfolded shape, which needs to be bent so that its two ends overlap, and then the overlapped part is sewn with sewing thread. After sewing, a filter core structure can be formed, and it can be put on the frame at this time; however, the main problems with this filter core structure are: (1) if the overlapped sewing part is located at one end of the filter core structure, it will be exposed after it is put on, resulting in a poor appearance; (2) since it needs to be bent, the filter core formed after bending is actually a two-layer structure, so the overlapped sewing part can be further bent and transferred to the inner side of the filter core. In this way, although its appearance and use effect can be improved, the overlapped sewing part will have a "convex ridge" structure, which will make the outer side of the filter core uneven (forming a "cross-section" state, affecting the water absorption effect), thereby greatly affecting the use effect and quality of the filter core; for this reason, we propose a filter core structure for a humidifier.
