Description

Technical Field

[0001] This utility model relates to the field of humidifiers, and in particular to a humidifier filter device that is easy to disassemble and the humidifier thereof. Background Technology

[0002] With the continuous development of society and the economy, more and more machines and equipment are being manufactured and widely used in agriculture, industry, and service sectors. These machines and equipment are diverse in type, and have undergone further innovation to meet different needs, playing an indispensable role in people's work and lives; they are ubiquitous. The internal structures of these machines and equipment are becoming increasingly complex, their functions increasingly diverse, and they are constantly being improved. Machines and equipment generally include heating devices, drive devices, speed change devices, transmission devices, working devices, braking devices, protective devices, lubrication devices, cooling devices, and so on, with each device playing a different role.

[0003] A humidifier is a household appliance that increases air humidity. The core function of a humidifier is to increase indoor humidity by atomizing or evaporating water, thus alleviating the effects of dry environments on the skin and respiratory tract, and improving user comfort. Based on different humidification technologies, humidifiers are mainly divided into three categories: ultrasonic humidifiers, cold evaporation humidifiers, and electric heating humidifiers.

[0004] Humidifiers typically include a filtration system to filter the water in the tank, improving its purity. Current humidifiers, such as the one in patent CN220958748U, have a first magnetic component on the end face of the filter holder near the filter cover, and a second magnetic component on the end face of the filter cover facing the filter holder. The filter holder and cover are magnetically connected using the second and first magnetic components. While this structure allows for easy disassembly and reassembly of the filter holder and cover, it has significant drawbacks: magnets are prone to corrosion and failure with prolonged water contact, leading to weakened adhesion and filter cover detachment, resulting in generally lower product quality and a shorter lifespan; secondly, the magnetic components, including magnets and metal sheets, result in higher material costs; and thirdly, the connection between the filter holder and cover is not robust enough, making the filter cover susceptible to detachment under external force, failing to meet current requirements. Therefore, it is necessary to research a new technical solution to address these issues. Utility Model Content

[0005] In view of the above, this utility model addresses the deficiencies of the existing technology. Its main purpose is to provide a humidifier filter device and humidifier that are easy to disassemble. It can effectively solve the problems in the existing magnetic adsorption humidifier filter device, which is easy to disassemble, but the magnet is prone to corrosion and failure when it is in contact with water for a long time, resulting in the weakening of the adsorption force and the detachment of the filter cover. The product quality is generally poor, the service life is short, the material cost is high, and the connection structure between the filter support and the filter cover is not stable enough, making the filter cover easy to fall off when subjected to external force.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A humidifier filter device that is easy to disassemble includes a filter support, a filter, and a filter cover. The filter support has a first snap-fit ​​portion at its upper end, and a positioning protrusion on its bottom surface. The filter is fitted onto the filter support. The filter cover has a second snap-fit ​​portion at its lower end, and a positioning groove on its top surface. The second snap-fit ​​portion engages with the first snap-fit ​​portion for detachable fastening. The positioning protrusion is detachably positioned within the positioning groove for positioning, effectively enhancing the stability of the connection between the filter cover and the filter support. The device has a simple structure, is easy and quick to assemble and disassemble, providing convenience for users. The filter cover and filter support work together to fix the filter in place.
