[0035] With the advancement of science and technology and the improvement of living standards, air conditioning functions are gradually developing towards intelligence, comfort and health. Modern consumers not only pay attention to cooling and heating, but also pay attention to the improvement of air quality, comfort and health by air conditioning. Especially in the current environment, air conditioners need to have fresh air and humidification functions to adjust indoor humidity and circulation to avoid dry air. The current window air conditioner in cooling mode is prone to dry indoor air, affecting comfort.

[0036] To this end, an embodiment of the present invention provides an air fresh air humidification device, which can realize fresh air exchange and humidification functions when the air conditioner 60 is running, thereby meeting consumers' diverse needs for air quality and comfortable life.

[0037] Specifically, the device achieves air filtration and humidification through the coordinated work of the pressurizing component 20, the filtering component 30 and the humidifying component 40 in the cavity 10, ensuring that the output air is both fresh and moist; through the air inlet and outlet control component 50, the opening and closing of the air inlet 11 and the air outlet 12 are adjusted, and the air flow direction is automatically switched to achieve the introduction of fresh air and ventilation of indoor air; the water storage tank 41 in the humidifying component 40 is combined with the oscillator 42 to release moisture into the air through vibration humidification, provide the required humidity, and improve comfort; the filtering component 30 adopts a HEPA filter to effectively remove harmful substances and bacteria in the air, ensuring that the air entering the room is cleaner; the control system accurately adjusts the working status of each component to enable the air conditioner to exchange fresh air while humidifying, thereby meeting consumers' diverse needs for air quality and a comfortable living environment.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] See also Figures 1 to 4 The above-mentioned air exchange humidification device includes: a cavity 10, a pressurizing component 20, a filtering component 30, a humidifying component 40 and an air inlet and outlet control component 50. The cavity 10 is provided with an air inlet 11 and an air outlet 12. The pressurizing component 20, the filtering component 30 and the humidifying component 40 are placed in the cavity 10 in sequence along the direction away from the air inlet 11. The cavity 10 is located below the whole machine air outlet 61 of the air conditioner 60, and the air inlet and outlet control component 50 is located above the cavity 10.

[0040] In this embodiment, the cavity 10 is the main structural frame of the entire device, which is used to accommodate various internal components. The cavity 10 is provided with an air inlet 11 and an air outlet 12, which are used to introduce outdoor air and discharge purified air respectively. The pressurizing component 20 sucks the air from the outdoor side into the cavity 10 from the air inlet 11. The filter component 30 purifies the inhaled air to remove fine particles and other pollutants. The humidifying component 40 is used to generate water mist. The water mist is mixed with the air purified by the filter component 30 to form fresh air with water vapor. The air inlet and outlet control component 50 is used to control the opening of the air outlet 12 and the fresh air inlet 11.

[0041] After the user turns on the fresh air function, the air inlet and outlet control component 50 works to expose the air outlet 12 and the fresh air inlet 11. The pressurizing component 20 draws the air from the outdoor side into the cavity 10 through the air inlet 11. The inhaled air is purified by the filter component 30 to remove fine particles and other pollutants. If the user needs humidification, start the humidification component 40 to generate water mist. The water mist is mixed with the air purified by the filter component 30 to form fresh air with water vapor. The purified air (or fresh air with water vapor) is blown into the room from the air outlet 12 to achieve indoor air renewal and humidification.

[0042] In addition, the cavity 10 of the present embodiment is located below the air outlet 61 of the air conditioner 60 , so that the space of the air conditioner 60 can be fully utilized and the additional occupied space can be reduced.

[0043] Integrating the fresh air exchange and humidification functions into one device reduces the number of devices and saves space. The air inlet and outlet control component 50 realizes automatic control of the air inlet and outlet 12, which is easy to operate and provides a good user experience. The filter component 30 can effectively remove fine particles and other pollutants in the air and provide high-quality indoor air. The humidification component 40 can be started according to user needs, flexibly adjust the indoor humidity, and improve comfort. The layout of the device is reasonable, and the cavity 10 is located below the air outlet 61 of the air conditioner 60, making full use of the existing space without increasing additional floor space. Through the design of the pressurization component 20, energy consumption is reduced and energy saving and environmental protection are achieved.

[0044] In one embodiment, see Figures 1 to 5 The cavity 10 includes a bottom shell 18, an upper top plate 13, a left side plate 14, a right side plate 15, a front side plate 16 and a rear side plate 17. The four sides of the upper top plate 13 and the four sides of the bottom shell 18 are respectively connected to the left side plate 14, the right side plate 15, the front side plate 16 and the rear side plate 17. The upper top plate 13 is provided with an air outlet 12, and the right side plate 15 is provided with an air inlet 11.

[0045] In this embodiment, the bottom shell 18 is the basic part of the cavity 10, which is used to support the entire device and provide a platform for installing other components. The upper top plate 13 is located at the top of the cavity 10, and is connected to the left side plate 14, the right side plate 15, the front side plate 16 and the rear side plate 17 on all sides to form a closed cavity 10. The upper top plate 13 is provided with an air outlet 12 for blowing purified air or fresh air with water vapor into the room. The left side plate 14 and the right side plate 15 are respectively located on both sides of the cavity 10, connected to the bottom shell 18 and the upper top plate 13, forming the side of the cavity 10. The right side plate 15 is provided with an air inlet 11 for introducing outdoor air. The front side plate 16 and the rear side plate 17 are respectively located at the front and rear ends of the cavity 10, connected to the bottom shell 18, the upper top plate 13, the left side plate 14 and the right side plate 15, forming the front and rear ends of the cavity 10.

[0046] Through the combination of the bottom shell 18, the top plate 13, the left side plate 14, the right side plate 15, the front side plate 16 and the rear side plate 17, a solid and stable cavity 10 structure is formed, which can effectively support the various components inside and ensure the long-term stable operation of the device. The tight connection of the surrounding panels makes the cavity 10 have good sealing performance, preventing unfiltered air from directly entering the room, ensuring the air purification effect. The design of the air inlet 11 on the right side plate 15 and the air outlet 12 on the top plate 13 makes the air flow path reasonable, the air intake and exhaust are smooth, and the air treatment efficiency is improved. The air inlet 11 is arranged on the right side plate 15, which can avoid the position conflict with the air outlet 12, reduce the air short circuit phenomenon, and ensure that the air is fully purified. The design of the cavity 10 is compact, making full use of the limited space, making the entire device small in size and suitable for installation in various indoor environments.

[0047] In one embodiment, see Figure 5 Two parallel mounting plates 161 are respectively provided on the front side plate 16 and the rear side plate 17 , a mounting gap 162 is provided between the two mounting plates 161 , and both ends of the filter assembly 30 are respectively embedded in the two mounting gaps 162 .

[0048] In this embodiment, two parallel mounting plates 161 are respectively mounted on the front side plate 16 and the rear side plate 17. An mounting gap 162 is left between each pair of mounting plates 161, and these gaps are used to install and fix the filter assembly 30. The two ends of the filter assembly 30 are embedded in the two mounting gaps 162. In this way, the filter assembly 30 is fixed inside the cavity 10 by the support of the mounting plate 161, and when the air flows through the filter area, effective air purification can be performed. The fixing method of the filter assembly 30 ensures its stability and reliability, thereby avoiding looseness or displacement during the operation of the equipment. The air enters the cavity 10 through the air inlet 11, and flows through the area where the filter assembly 30 is installed when passing through the cavity 10. Since the filter assembly 30 is fixed in the mounting gap 162 of the mounting plate 161, the filtering process can be carried out efficiently, and impurities such as pollutants and particulate matter are filtered out, thereby purifying the air.

[0049] In one embodiment, see Figure 6 The pressurizing assembly 20 includes a bracket 21 , a second power source 22 and a fan blade 23 . The second power source 22 is connected to the bracket 21 . The bracket 21 is connected to the cavity 10 . The fan blade 23 is connected to the second power source 22 .

[0050] In one embodiment, the filter assembly 30 comprises a HEPA filter. The HEPA filter is a mature product, which is mainly composed of a stack of sub-glass fiber membranes folded back and forth continuously to form a wavy gasket, which can effectively remove fine particles, thereby achieving the effect of purifying the air.

[0051] In this embodiment, the bracket 21 serves as a supporting structure for the pressurizing assembly 20. The bracket 21 not only plays a fixing role, but is also responsible for stably installing the entire pressurizing assembly 20 into the cavity 10 of the fresh air duct system. This ensures that the assembly remains stable even at high wind speeds, avoiding noise and performance degradation caused by vibration.

[0052] The second power source 22 is connected to the bracket 21 and is responsible for driving the blades 23 to rotate. The selection of the second power source 22 needs to consider the balance between energy efficiency and output power to ensure that sufficient wind power can be provided while maintaining a low energy consumption level.

[0053] The fan blades 23 are connected to the second power source 22. When the power source is started, the fan blades 23 rotate accordingly, generating a strong airflow, accelerating the suction and pushing of outdoor fresh air into the room. The design of the fan blades 23 optimizes the airflow path, reduces resistance, and increases the speed and flow of the airflow.

[0054] In this embodiment, the HEPA (High Efficiency Particulate Air) filter is a high-efficiency air filtration device, which is widely used in places that require a high cleanliness environment. It is mainly composed of a stack of sub-glass fiber membranes that are folded back and forth continuously to form a unique wavy gasket structure. This design greatly increases the filtration area and improves the filtration efficiency. The HEPA filter can effectively capture fine particles in the air, including dust, pollen, smoke particles, etc. The quality of the purified air is significantly improved, which is especially beneficial for people with allergies.

[0055] Through the efficient filtering effect of the HEPA filter, harmful particles in the air can be effectively removed, providing a cleaner and healthier indoor environment. When used in conjunction with a humidification system, the fresh air duct system can not only bring in fresh air, but also regulate indoor humidity to create more comfortable living conditions. The optimized design of the pressurized component 20 helps to reduce energy consumption while ensuring efficient air circulation capacity, achieving the goal of energy conservation and emission reduction. The stable bracket 21 design reduces vibration and noise during operation, providing users with a quiet living space. As a mature product, the HEPA filter is usually designed with a convenient replacement mechanism to facilitate regular maintenance and replacement, ensuring the long-term and efficient operation of the system.

[0056] In one embodiment, see Figure 7 and Figure 8 The humidifying assembly 40 includes a water tank 41 and an oscillator 42 , and the oscillator 42 is located below the water tank 41 .

[0057] In this embodiment, in the humidification component 40, the user adds water to the water storage tank 41 and starts the ultrasonic oscillator 42, so that the water is converted into fine water mist under the action of the oscillator 42. The ultrasonic oscillator 42 is located at the bottom of the water storage tank 41, and the sealing of the device is ensured by components such as a sealing ring 43 to prevent water leakage.

[0058] The humidification assembly 40 includes two key parts: a water storage tank 41 and an ultrasonic oscillator 42. The water storage tank 41 provides a water source, and the ultrasonic oscillator 42 breaks up water molecules through high-frequency oscillation to form tiny water mist and release it into the air to achieve a humidification effect.

[0059] The ultrasonic oscillator 42 produces fine water mist through high-frequency oscillation, which can quickly increase the humidity in the air. Compared with traditional evaporative humidifiers, ultrasonic humidifiers can release moisture into the air more efficiently and quickly humidify the entire room. The water mist has a small particle size and can be evenly diffused into the indoor air without forming water droplets, avoiding the problem of water accumulation in a humid environment. This allows the indoor humidity to be accurately adjusted to provide a more comfortable air quality. The ultrasonic oscillator 42 is closely matched with the water storage tank 41 through a sealing ring 43 and other devices to effectively prevent water from leaking out. This sealing design ensures the safety and cleanliness of the humidifier and prevents moisture from leaking to the outside of the device or polluting the environment. The working principle of the ultrasonic oscillator 42 does not require heating of the water source, so it has low energy consumption and high efficiency. This low-energy humidification method is both environmentally friendly and reduces the cost of use. The ultrasonic oscillator 42 has a high oscillation frequency when working, but does not produce obvious noise. Compared with traditional humidifiers, ultrasonic humidifiers are almost noiseless and are very suitable for users who need a quiet environment, such as bedrooms or offices. The user only needs to add water to the water tank 41 and start the oscillator 42, and the device can work automatically without frequent operation or maintenance. The humidification process is intelligent and continuous, and does not require much intervention from the user.

[0060] In one embodiment, see Figures 1 to 3 , Fig. 9 The above-mentioned air inlet and outlet control component 50 includes a driving component, a moving rod 52, an air outlet baffle 53, an air inlet baffle 54 and a bottom plate 55. The air inlet baffle 54 is connected to one end of the bottom plate 55 away from the air outlet 61 of the whole machine, and the driving component is connected to the moving rod 52, the driving component is connected to the bottom plate 55, and the air outlet baffle 53 is connected to the moving rod 52.

[0061] In this embodiment, the air inlet baffle 54 is located above the inlet air, and is used to prevent the air from the air inlet 11 from being directly output from the air outlet 61 of the whole machine without passing through the cavity 10.

[0062] In one embodiment, see Fig. 9The above-mentioned driving assembly includes a first power source 51, a gear 56 and a rack 57. The gear 56 is connected to the first power source 51, and the first power source 51 is installed under the base plate 55. The rack 57 is connected to the side of the moving rod 52 close to the air inlet baffle 54, and the rack 57 is meshed with the gear 56.

[0063] In one embodiment, see Fig. 9 The air inlet baffle 54 is vertically connected to one end of the bottom plate 55 away from the whole machine air outlet 61. The air inlet baffle 54 and the side plate near the air inlet 11 in the air conditioner 60 enclose and block the channel directly output from the whole machine air outlet 61, thereby preventing the air in the air inlet 11 from being directly output from the whole machine air outlet 61.

[0064] In this embodiment, the driving assembly is a core component for controlling the movement of the moving rod 52 and is responsible for realizing the opening and closing of the air outlet 12 and the air inlet 11. Specifically, the driving assembly includes a first power source 51, a gear 56 and a rack 57.

[0065] The first power source 51 is installed below the bottom plate 55 to provide necessary driving force to rotate the gear 56. The first power source 51 includes but is not limited to a stepping motor.

[0066] The gear 56 is connected to the first power source 51 , receives the driving force of the power source, and transmits the driving force to the rack 57 .

[0067] The rack 57 is connected to one side of the moving rod 52 close to the air inlet baffle 54 and meshes with the gear 56. When the gear 56 rotates, the rack 57 moves in a straight line direction, driving the moving rod 52 to move forward or backward.

[0068] The moving rod 52 is connected to the air outlet baffle 53 and is controlled by the driving component to move forward and backward, thereby opening or closing the air outlet 12 and the air inlet 11.

[0069] The air outlet baffle 53 is connected to the moving rod 52 and moves with the movement of the moving rod 52 to control the opening and closing of the air outlet 12.

[0070] The air inlet baffle 54 is connected to one end of the bottom plate 55 away from the whole machine air outlet 61, and is located above the inlet air, and is used to prevent the untreated air from the air inlet 11 from being directly output from the whole machine air outlet 61. The air inlet baffle 54 is vertically connected to one end of the bottom plate 55 away from the whole machine air outlet 61, and is enclosed with the side panel of the air conditioner 60 near the air inlet 11, blocking the channel directly output from the whole machine air outlet 61, ensuring that all incoming air must be processed (such as filtered, humidified, etc.) in the cavity 10.

[0071] When the fresh air function needs to be turned on, the first power source 51 is started, and the moving rod 52 is moved forward through the cooperation of the gear 56 and the rack 57. At this time, the air outlet baffle 53 and the air inlet baffle 54 on the moving rod 52 are respectively moved away from the air outlet 12 and the air inlet 11, so that the fresh air can pass smoothly. When the fresh air function needs to be turned off, the first power source 51 is started in the reverse direction, and the moving rod 52 is moved backward through the cooperation of the gear 56 and the rack 57. At this time, the air outlet baffle 53 and the air inlet baffle 54 on the moving rod 52 are respectively moved to the position of the air outlet 12 and the air inlet 11, and finally fit the entire fresh air outlet to achieve blocking. The gear 56 rack 57 mechanism driven by the stepper motor can achieve precise control of the position of the moving rod 52 to ensure that the opening and closing operations of the air outlet 12 and the air inlet 11 are accurate. The air inlet baffle 54 is enclosed with the inner side plate of the air conditioner 60 to form a good sealing effect, effectively preventing untreated air from being directly output from the air outlet 61 of the whole machine, thereby ensuring the air quality. The layout of each component is reasonable, the structure is compact, and the space occupied is small, which is suitable for air conditioners 60 of various sizes. The mature gear 56 rack 57 transmission method is adopted, and the mechanical structure is simple and reliable, with low failure rate and long service life. The design of the air inlet baffle 54 and the air outlet baffle 53 is easy to disassemble and clean, and the maintenance is simple, ensuring the long-term and efficient operation of the system.

[0072] In summary, the air inlet and outlet control component 50 in this embodiment achieves precise control of the air outlet 12 and the air inlet 11 through a scientific and reasonable structural design, thereby ensuring the efficient operation of the fresh air system and the user experience.

[0073] In one embodiment, the driving assembly can also be driven by a pulley.

[0074] In this embodiment, the pressurizing assembly 20 is close to the outdoor side, and the humidifying assembly 40 is close to the indoor side.

[0075] Specifically, the working process of the whole device is as follows:

[0076] The user selects to turn on the fresh air function through the remote control or the button on the device panel. After the system receives the user's command, the built-in control system activates the stepper motor. After the stepper motor is started, the gear 56 on its output shaft begins to rotate. When the gear 56 rotates, the rack 57 meshing with it drives the moving rod 52 to move toward the indoor side. As the moving rod 52 moves, the air outlet baffle 53 and the air inlet baffle 54 fixed thereon move away from the air outlet 12 and the air inlet 11 respectively, so that the two ports are fully opened.

[0077] After the air vent and the air inlet 11 are opened, the system starts the fan blade 23, and the fan blade 23 starts to rotate. The rotation of the fan blade 23 generates negative pressure, and the air on the outdoor side is sucked into the system through the fresh air inlet 11. The inhaled outdoor air is purified by the HEPA filter to remove fine particles such as dust, pollen, bacteria, etc., to ensure clean air.

[0078] The air purified by the HEPA filter is converted into the fresh air required by the user, and can be directly blown into the room through the air outlet 12 to improve the indoor air quality. If the user needs to humidify at the same time, the system will start the ultrasonic humidifier. The ultrasonic humidifier produces fine water mist particles. The generated water mist is mixed with the fresh air purified by the HEPA filter to form fresh air with water vapor. The mixed fresh air with water vapor is blown into the room through the air outlet 12, achieving the effect of both fresh air exchange and humidification.
