Description

[Technical Field]

[0001] The present invention particularly relates to a humidifier with antibacterial drying function. [Background technology]

[0002] Humidifiers, especially ultrasonic humidifiers, have become a common device for improving indoor air humidity. The basic principle is to split water into ultra-fine mist through an atomizer (such as an atomizing sheet) and then blow it into the air using an air device.

[0003] However, conventional humidifiers suffer from the drawback of leaving a large amount of moisture inside them, especially in the mist passage, after they are shut down. The mist passage has a complex structure, is narrow, and has poor ventilation, preventing the remaining water from evaporating and drying, resulting in a high humidity level for a long period of time. This creates a high humidity and makes it easy for bacteria, mold, and other microorganisms to multiply in such a confined, humid environment. When the humidifier is turned on, these microorganisms are released into the air along with the mist, posing a risk to the user's health and resulting in problems such as "secondary pollution" and "white powder." This is a technical pain point that has plagued the ultrasonic humidifier industry. Summary of the Invention [Problem to be solved by the invention]

When the blocking component is in the first position, it can block communication between the mist passage and the hot air passage. When the blocking component is in the second position, it connects the mist passage and the hot air passage, and the airflow generated by the blowing module flows through the mist passage to dry the mist passage.

[0006] Preferably, the drive component includes a motor, a gear driven by the motor, and a rack meshing with the gear, the rack being connected to the blocking component via a transmission member, and the motor drives the gear to rotate, causing the rack to move linearly, and further drives and moves the blocking component via the transmission member.

[0024] Furthermore, the blocking component includes a stopper 61 , and a return spring 62 is provided between the stopper 61 and the fuselage 1 .

When the rack 52 is moved upward, the magnetic repulsive force pushes the stopper 61, overcoming the elastic force of the return spring 62, and the rack 52 can move upward.

[0026] Furthermore, the hot air passage 3 and the mist passage 2 are connected through a connecting duct 8, the blower module is provided in the connecting duct 8, and the blocking component is provided at the connection between the connecting duct 8 and the mist passage 2.

[0027] Furthermore, the air blowing module includes a fan 91 and a heat generating component 92, and the airflow generated by the fan 91 is heated by the heat generating component 92 and then forms hot air that flows into the mist passage 2.

[0028] Furthermore, a flow guide cover 10 is provided on the outer periphery of the hot air passage 3, and a gap is provided between the flow guide cover 10 and the hot air passage 3 to form a ring-shaped duct for discharging hot air.

[0029] Furthermore, a heat dissipation hole 12 is formed in the wall of the machine body 1 to discharge the hot air generated from the hot air passage 3 to the outside of the machine body 1.

[0030] Furthermore, a water tank cover 13 is provided on the outlet side of the mist passage 2, and a nozzle 14 for spraying mist is formed on the water tank cover 13.

[0031] The working principle of this invention is as follows.

[0032] As shown in FIG. 1, the automatic dry humidifier includes a body 1. Inside the body 1 is a water storage chamber 1-1 for storing water to be atomized. The core functional structures inside the body 1 are a mist passage 2 and a hot air passage 3, which are physically isolated from each other. The bottom of the mist passage 2 extends to the water storage chamber 1-1. An atomizer 4, which in this embodiment is an atomizing sheet, is installed at the bottom of the mist passage 2 and immersed below the water level in the water storage chamber 1-1. When the atomizing sheet is activated, high-frequency vibrations directly break up the liquid water adhering to its surface into micrometer-sized mist. A water tank cover 13 is fixed to the top outlet side of the mist passage 2 by screw connection or snap, and a nozzle 14 is molded on the water tank cover 13 for spraying concentrated mist.

[0033] In this application, a blower module is integrated into the hot air passage 3, and this blower module includes a fan 91 and a heat-generating component 92. Airflow is generated by operation of the fan 91, and as the airflow passes through the heat-generating component 92, it is heated and becomes dry hot air. The mist passage 2 and the hot air passage 3 are connected via a connecting duct 8, and the heat-generating component 92 is provided within this connecting duct 8. A movable blocking component is provided at the connection between the connecting duct 8 and the mist passage 2.

[0034] 2, the blocking component includes a stopper 61 that can move up and down. A return spring 62 is connected between the stopper 61 and the machine body 1. When no external force is applied, under the action of the return spring 62, the stopper 61 is in the first position by default, and the stopper 61 blocks the outlet of the connecting duct 8, blocking the path of hot air entering the mist passage 2.

[0035] The blocking component is controlled by a driving component. The driving component includes a motor 50, a gear 51 driven by the motor 50, and a rack 52 meshing with the gear 51. The rack 52 is linked to the stopper 61 via a transmission member. In this embodiment, the transmission member is a non-contact magnetic transmission member, and includes an upper magnet 71 fixed to the bottom of the stopper 61 and a lower magnet 72 fixed to the top of the rack 52. The upper magnet 71 and the lower magnet 72 have the same magnetic pole on their opposing surfaces.

[0036] Humidification process: The system is powered on and the humidification mode is selected. The motor 50 is not operating, and the stopper 61 is in the first position under the action of the return spring 62, blocking communication. When the atomizing sheet is activated, mist is generated and sprayed from the nozzle 14. The air blowing module can be closed or operated independently, and the air is exhausted through the heat dissipation hole 12 to provide the warm air function.

[0037] Self-drying function: After humidification is completed or a drying command is received, the system switches to self-drying mode. Motor 50 starts, rotating gear 51 and moving rack 52 upward in a linear motion. As rack 52 rises, lower magnet 72 on rack 52 approaches upper magnet 71 on stopper 61. As shown in Figure 5, the repulsion of like poles generates a magnetic repulsive force, pushing stopper 61 upward to its second position, overcoming the elastic force of return spring 62 and opening the outlet of connecting duct 8. The air blowing module also starts, operating fan 91 and heat-generating components 92. The generated dry hot air flows through connecting duct 8 into mist passage 2, completely drying all components therein. After drying is completed, motor 50 reverses, moving rack 52 downward. The magnetic repulsive force disappears, and stopper 61 automatically returns to its first position under the action of return spring 62, closing the passage and preparing for the next humidification cycle.

[0038] In Example 2, both the lower ends of the hot air passage 3 and the mist passage 2 are connected to the water storage chamber 1-1 (liquid water is stored in the area indicated by "a" in Figure 6; the arrows indicate the schematic diagram of the hot air flow). Here, the inlet position of the connecting duct 8 is raised much higher than the normal water level in the water storage chamber 1-1 to prevent liquid water from flowing back into the connecting duct 8. The atomizing sheet operates normally to convert the water in the water storage chamber 1-1 into mist, which rises and is sprayed from the nozzle 14. At the same time, the blower module (fan 91 and heat-generating component 92) also starts, generating dry hot air. At this time, the blocking component is in the second connected position. The hot air enters the mist passage 2 through the connecting duct 8. The hot air generated by the fan 91 and heat-generating component 92 is blocked by the liquid water in the lower water storage chamber 1-1 and cannot flow downward to enter the hot air passage 3, so all the hot air flows upward to enter the mist passage 2. When the hot air rises, it mixes well with the mist generated from the atomizing sheet to spray out a warm mist, which avoids the cold irritation and is particularly suitable for use in winter by elderly people and families with infants.

[0039] Based on the above technical solution, a guide cover 10 is provided at the outlet of the hot air passage 3, and a gap is provided between the guide cover 10 and the hot air passage 3 to form a ring-shaped duct for discharging hot air. A heat dissipation hole 12 is provided on the side wall or top of the machine body 1 to discharge hot air to the outside of the machine body 1.

[0040] In the dry humidifier of the present application, when the humidification mode is used, the driving module drives the blocking component to move it to a first position, physically isolating the mist passage 2 from the hot air passage 3. At this time, the atomizer 4 in the mist passage 2 operates independently, and the generated mist is smoothly sprayed through the nozzle 14 to humidify the air. Meanwhile, the blowing module in the hot air passage 3 is not operating, or the generated hot air is directed to the heat dissipation hole 12, preventing interference between the two. When the self-drying mode is used, the driving component is activated and drives the blocking component to move it to a second position, establishing a communication path between the mist passage 2 and the hot air passage 3. At this time, the blowing module is activated, and the airflow generated by the fan 91 is heated by the heat-generating component 92 to form dry, hot air. This hot air is introduced into the mist passage 2 through the communicating passage and dries its inner wall, the atomizing sheet, and other components, achieving self-drying of the equipment. This fundamentally solves the problem of conventional humidifiers, where moisture remains inside, easily causing mold and unpleasant odors.

[0041] This device's mode-switching design allows dry, hot air to flow into the mist passage 2 after the humidifier is turned off. This directly eliminates the high-humidity environment necessary for bacteria and mold growth, fundamentally preventing "secondary contamination," ensuring the cleanliness of the mist emitted and protecting the user's respiratory health. Furthermore, the use of a movable blocking component allows the mist passage 2 and the hot air passage 3 to be switched between "communication" and "blocking." This integrated design adds powerful self-drying capabilities while minimizing the need for a complex structure and increased costs.

Therefore, the above embodiments are merely for explaining the present invention in detail, and are not intended to limit the present invention.
