Description

Technical Field

[0001] The invention belongs to the technical field of small household appliances, and in particular relates to a humidifying component and a humidifier with a large humidification capacity. Background Art

[0002] Humidifiers on the market are currently divided into two types: ultrasonic and water-heated. Ultrasonic humidifiers have a large amount of water mist, which is easy to attach to floating objects in the air and be inhaled into the body, which is unhealthy; water-heated humidifiers have a small humidification capacity (humidification capacity is about 300g / hour, and the noise level is less than 40dB at a distance of 50cm).

[0003] The Chinese patent with the authorization announcement number CN2450577Y discloses a heater with a humidifier, which consists of a fan, an electric heating element, a swing mechanism, an atomizer, a water tank and a casing. The atomizer is fixed on the rear cover of the casing, and it consists of a pool, an ultrasonic transducer and a small fan. The ultrasonic transducer is installed in the through hole at the bottom of the pool. When the ultrasonic transducer and the small fan are working, water mist appears above the water surface of the pool. The small fan sends air to the water surface of the pool through the air duct, and drives the water mist out of the machine from the exhaust port, thereby humidifying the air in the room. The heater achieves the humidification effect by atomizing the water in the pool, but the water in the form of mist entering the environment is easy to absorb floating objects such as dust and bacteria in the air, and inhalation by the human body will have an impact on health. Summary of the invention

[0004] In view of the above problems existing in the prior art, an object of the embodiments of the present invention is to provide a humidifying component and a humidifier with a large humidification capacity, and the steam provided by the humidifier is not easy to adsorb floating objects in the air.

The hot air module has a simple structure and good air supply effect; the air outlet is designed to supply air from the side to avoid affecting the upward flow of steam, which is beneficial to the diffusion of steam and accelerates the evaporation of water.

[0012] In some embodiments, the fan support has a steam passage connected to the water heating tank; the hot air module is located outside the steam passage. Placing the hot air module outside the steam passage is beneficial to protecting the hot air module from corrosion caused by steam immersion and extending its service life.

The structure is compact and reasonable, and the steam is only discharged through the hollow part to prevent the steam from running wildly, thereby improving the utilization rate of the steam.

[0031] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0032] like Figures 1 to 3 As shown, an embodiment of the present invention provides a humidifying component 1, which is applied to a humidifier. The humidifying component 1 includes a water-boiling tank 11 for generating steam, and the humidifying component 1 also includes a hot air module, which is used to generate hot air and send the generated hot air into the water-boiling tank 11 to blow the steam in the water-boiling tank 11 to quickly overflow and accelerate the evaporation of water in the water-boiling tank 11.

[0033] The humidification assembly 1 of the embodiment of the present invention is equipped with a hot air module, which can blow the steam in the water-boiling tank to accelerate the diffusion outward, thereby reducing the amount of steam above the water surface, which is conducive to the evaporation of water in the water-boiling tank 11 into steam, accelerates the evaporation of water, and increases the humidification amount. In addition, the use of hot air to promote the flow of steam will not cause the steam to cool down and condense, thereby ensuring the humidification amount.

[0034] In some embodiments, Figure 1 and Figure 2 As shown, the humidification component 1 also includes a water stirring mechanism, which is at least partially located in the water-boiling tank 11 and is used to stir the water in the water-boiling tank 11 so that the static water becomes flowing water. During the stirring process, the water stirring mechanism can reduce the noise generated when the water is boiled in the water-boiling tank 11. Within a distance of 50 cm, the noise can be reduced to below 30 dB, so that the user can use it with confidence when resting or sleeping, thereby improving the user experience. Moreover, the water stirring mechanism makes the water in the water-boiling tank 11 become flowing water, and at the same time, it can also increase the evaporation rate, increase the humidification amount, and improve the humidification effect.

[0035] In the above-mentioned embodiment, the hot air module and the water stirring mechanism can work together to significantly increase the humidification amount and improve the humidification effect, and at the same time also achieve the purpose of noise reduction, so that the humidification component has a broad application prospect.

[0036] In some embodiments, continue to combine Figure 1 and Figure 2 The humidification assembly 1 further includes a fan bracket 12 located above the water-boiling tank 11, and the hot air module is arranged on the fan bracket 12.

That is, the lower port of the steam channel 121 is sealed and connected to the upper port of the water-boiling tank 11, so that all the steam in the water-boiling tank 11 enters the steam channel 121 to prevent the steam from running around. An independent steam channel 121 is provided to allow the steam to be discharged quickly and avoid loss during the steam discharge process. The hot air module is arranged outside the steam channel 121, which is conducive to protecting the hot air module from being corroded by steam immersion and extending the service life.

This embodiment shows two water stirring blades 18, and the specific structure of the water stirring blades 18 is not limited, as long as it can move water to eliminate the noise generated when it is heated.

[0043] In order to reduce weight, the stirring rod 17 is designed as a hollow rod. The adoption of the hollow rod is also conducive to the transmission connection with the output shaft of the motor 16. For example, the output shaft is inserted into the upper end of the hollow rod.
