Description

Technical Field

[0001] The invention relates to the technical field of humidifiers, in particular to a humidifier with a self-cleaning function. Background Art

[0002] In the dry areas of northern my country, many families use humidifiers to increase the humidity of the air at home. With the continuous development of the domestic economy and the continuous improvement of people's living standards, more and more families begin to pay attention to the quality of life and health, and the requirements for the function and quality of humidifiers are also increasing. Usually, humidifiers use ultrasonic waves to vibrate water at high frequency, so that the water is atomized into ultrafine particles, and then spread into the air to increase the humidity of the air. Using a humidifier can not only refresh the air and improve health, but also provide a more comfortable life for the family;

[0003] A humidifier such as "CN103912950B" includes a humidifier shell, a water tank, a water supply assembly, a humidifying disk, a drive assembly and a fan assembly. The humidifier shell is provided with an air outlet and an air inlet. The water tank is arranged in the humidifier shell. The water supply assembly is arranged in the humidifier shell and is configured to fill water into the water tank when the water level in the water tank is lower than a first predetermined water level, and to stop filling water when the water level in the water tank is higher than a second predetermined water level. The humidifying disk is arranged in the humidifier shell and the bottom of the humidifying disk is located in the water tank. The humidifying disk includes a disc-shaped humidifying disk shell and a humidifying core coaxially installed in the humidifying disk shell. The drive assembly is arranged in the humidifier shell, and is used to drive the humidifying disk to rotate around its central axis. The fan assembly is arranged in the humidifier shell. The humidifier of the present invention is small in size and has a good humidification effect;

[0004] However, in the prior art, as shown in the above patent, when using a humidifier, water stains accumulated inside the ordinary humidifier for a long time are prone to breed bacteria, and the water mist sprayed into the room is easy to spread bacteria after being inhaled by people. In addition, most households use tap water to fill the humidifier, which is also easy to cause scale to form in the humidifier, causing damage to the humidifier. When cleaning, it is usually disassembled for cleaning. If the humidifier has a more complex structure, it is easy to assemble incorrectly, which is time-consuming and labor-intensive.

The sealing gasket is provided to ensure the sealing of the connection of each part, and to avoid water overflowing from the placement slot and the drainage slot into the drainage cavity during normal use.

[0022] 4. When the present invention discharges sewage, the rack is driven to slide by driving the first cylinder, thereby driving the adjacent second gear and the third gear to rotate synchronously in opposite directions.

[0049] Working principle: When the humidifier is in normal use, people can add water to the water tank 8, the water flows into the filter plate 9 for filtration, and the filtered water flows into the water tank 2 for storage. The motor built into the humidifier body 1 drives the humidifying roller 4 to rotate, and the humidifying roller 4 absorbs water on the surface and uses the fan 3 to drive the air flow to evaporate the water to achieve the humidification effect, and the mist is discharged from the air outlet 5. During self-cleaning, water is added to the water tank 8, and the humidifying roller 4 still rotates to connect the nozzle 132 with the water source. At the same time, the storage rack 104 and the flap 103 are rotated to open. The flap 103 is in a horizontal state after opening, and the filter plate 9 is connected to the sewage discharge chamber 6. The cleaning roller 114 on the storage rack 104 is turned over to the water tank 2, and the second cylinder 113 is driven to drive the outer frame 112 and the inner frame 111 to rotate and unfold and push the cleaning roller 114 The cleaning roller 114 and the humidifying roller 4 are both in a rotating state. The rotation of the cleaning roller 114 can clean the surface of the humidifying roller 4 in all directions. The cleaned dirt falls into the water in the water tank 2. The nozzle 132 sprays water to the filter plate 9 to flush the attached dirt inside the filter plate 9, and the dirt flows into the sewage chamber 6 along the lower inclined surface of the filter plate 9, wherein the ultrasonic generator 22 converts the electrical energy into an electrical signal, and the ultrasonic transducer head 14 converts the electrical signal into mechanical vibration, and vibrates and cleans every corner of the water tank 2. After cleaning, the cover 232 is rotated to open, so that all the sewage is discharged into the sewage chamber 6 and discharged through the sewage pipe 122. The above steps can be repeated for secondary cleaning to flush away the residual dirt in the water tank 2 and the sewage chamber 6 to ensure the quality of cleaning.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
