Description
Technical Field
[0001] This invention belongs to the field of air purifier technology, specifically relating to an air purifier with humidification function. Background Technology
[0002] With the continuous improvement of people's living standards and increasing attention to indoor air quality, air purifiers have gradually become an indispensable environmental appliance in homes and offices. Especially during dry seasons or in environments where air conditioning and heating are frequently used, air humidity drops significantly, easily leading to problems such as dry skin and respiratory discomfort. Therefore, integrated devices that combine air purification and humidification functions have emerged and are widely welcomed by the market.
[0003] Existing air purifying humidifiers typically employ a side-intake, top-outflow airflow design. Air enters from the side, passes through a filter for purification, is processed by the humidification module, and is then discharged as clean, humidified air from the top. While this structure achieves a degree of integration of purification and humidification, it still suffers from several technical drawbacks: First, the vertical stacking of core components such as the fan, water tank, and humidification module results in a large overall height, occupying significant space and hindering miniaturization and compact design. Second, the humidification water source usually relies on a single water tank, requiring users to stop the machine when adding water, disrupting continuous operation. Third, the humidification filter tends to accumulate impurities over time; without an effective self-cleaning mechanism, this reduces humidification efficiency and may cause secondary pollution.
[0004] Therefore, there is an urgent need to provide an air purifier with humidification function that is compact in structure, efficient in operation, convenient to add water, and has self-cleaning ability, in order to overcome the problems of low space utilization, need to stop the machine to add water, easy contamination of humidification filter and insufficient purification capacity in the existing technology. Summary of the Invention
[0005] The purpose of this invention is to address the aforementioned problems in the prior art by providing an air purifier with a humidification function.
[0006] The objective of this invention can be achieved through the following technical solution: an air purifier with humidification function, comprising: Humidification components; The first water tank is located below the humidification component. The first water tank is hollow, and the hollow part of the first water tank is an airflow channel. The first fan is located below the first water tank and is at least partially located in the hollow part of the first water tank.

[0008] As a further improvement of the present invention, the humidification assembly includes a humidification filter and a humidification top cover. The humidification filter is disposed on the top of the first water tank, and the humidification top cover is disposed on the top of the humidification filter. A plurality of water collection holes are provided on the top of the first water tank corresponding to the humidification filter, and the water collection holes are evenly distributed circumferentially.
[0009] As a further improvement of the present invention, the humidifying top cover is provided with an annular water channel, and the annular water channel is provided with a plurality of humidifying holes opposite to the humidifying filter. The inner wall of the humidifying top cover is provided with a first water inlet, one end of the first water inlet is connected to the first water tank, and the other end of the first water inlet is connected to the annular water channel.
[0010] As a further improvement of the present invention, a groove is provided on the outer wall of the first water tank, and a first water pump is provided in the groove. One end of the first water pump is connected to the first water tank, and the other end of the first water pump is connected to the first water inlet.
[0011] As a further improvement of the present invention, the humidification assembly further includes a support frame and a support column disposed in the support frame. One end of the support frame and the support column are connected to the humidification top cover, and the other end is connected to the top surface of the first water tank. The humidification filter is sleeved on the support frame, and the water pipe between the first water tank and the first water inlet passes through the support column.
[0012] As a further improvement of the present invention, a second water tank is also included, which is disposed on the top of the humidifying top cover. A second water inlet is provided on the inner wall of the humidifying top cover, which communicates with the annular water channel. The second water tank is connected to the second water inlet.
[0013] As a further improvement of the present invention, a drain valve is provided between the bottom of the second water tank and the top of the humidifying top cover, and a second water pump is provided on the lower side wall of the humidifying top cover. One end of the second water pump is connected to the drain valve, and the other end of the second water pump is connected to the second water inlet.
[0014] As a further improvement of the present invention, it also includes a first purification filter, which is detachably sleeved on the outside of the humidification assembly.
[0015] As a further improvement of the present invention, a purification component is also included, which is disposed below the humidification component.
[0016] Based on the above technical solution, the present invention can produce at least the following technical effects: 1. By designing the first water tank as a hollow structure and embedding the first fan at least partially into the air flow channel in the hollow structure, the internal space in the vertical direction is effectively utilized, avoiding the volume redundancy caused by simply stacking the fan, water tank, and humidification module along the height direction in traditional equipment. 2. In this invention, the first air inlet is located on the side of the humidification component, and the first air outlet is located on the side of the first fan and below the air inlet, forming an airflow path of intake in the middle and exhaust at the bottom. This design avoids the humid airflow blowing directly upwards towards the human body, reducing the risk of condensation dripping. At the same time, it is more in line with the natural convection law of indoor air, which helps to humidify evenly and improve the user's physical comfort. 3. The present invention adds a detachable second water tank at the top. When the second water tank is filled with water, the water flows from top to bottom through the humidifying filter, which can wash away the dust and impurities attached to the surface of the filter, realize the automatic cleaning of the humidifying filter, extend its service life and ensure the cleanliness of the humidifying water. Even when the second water tank is removed and water is added, the first water tank can continue to supply water to the humidifying system, ensuring that the air purification and humidification functions continue to operate without stopping the machine, which greatly improves the user experience and equipment availability. 4. An independent purification component is set up below the humidification component to form a dedicated purification channel parallel to the humidification air duct. This design not only avoids the interference of the humidification process on the purification efficiency, but also greatly increases the air handling capacity per unit time through the dual fan and dual air duct structure. 5. The humidifying filter is detachably mounted on the outside of the support frame. The first purification filter also adopts a detachable mounting structure, allowing users to quickly replace or clean the filter without tools. The second water tank is located on the top, making it easy to observe the water level and add water directly, thus improving the product's ease of use and maintainability.

[0028] The following are specific embodiments of the present invention, in conjunction with the appendix. Figure 1-8 The technical solution of the present invention will be further described below, but the present invention is not limited to the following embodiments.
[0029] This invention relates to an air purifier with humidification function, featuring a vertical columnar structure that allows for flexible placement in indoor spaces while maintaining both aesthetics and functionality. The device primarily comprises a housing 100, a humidification component 200, a first water tank 300, a first fan 400, a second water tank 500, a purification component 700, and multiple filter modules. These components are integrated within the housing 100 according to a specific spatial layout to achieve efficient and coordinated operation of air purification and humidification functions.
[0030] The housing 100 serves as the external support structure for the entire device and is typically made of high-strength engineering plastics or metal, possessing excellent structural strength and sealing performance. The housing 100 is equipped with a first air inlet 110, a first air outlet 120, a second air inlet 130, and a second air outlet 140. The first air inlet 110 is located on the upper side wall of the housing 100, corresponding to the side position of the humidification component 200; the first air outlet 120 is located below the first air inlet 110, forming an airflow path that draws in from the side and discharges downwards from the side. This design differs from traditional top-exhaust structures, effectively preventing humidified air from blowing directly onto the user's head, improving user comfort and safety.
[0031] In addition, the bottom area of the housing 100 is provided with a second air inlet 130 and a second air outlet 140, both of which are located on the side of the area where the purification component 700 is located. The second air inlet 130 is arranged along the axis of the second fan 720, and the second air outlet 140 is arranged in the vertical direction of the axis, forming an independent purification air duct with horizontal air intake and side air outlet.
[0032] Inside the housing 100, a second water tank 500, a humidification component 200, a first water tank 300, and a first fan 400 are arranged sequentially from top to bottom. The second water tank 500 is detachably mounted on the top of the housing 100, allowing the user to easily remove it for adding water or cleaning. The bottom of the second water tank 500 is connected to the lower humidification top cover 220 via a drain valve 510, which can be electromagnetically controlled to regulate the water flow. The inner wall of the humidification top cover 220 has a second water inlet 224, which communicates with an annular water channel 221. The annular water channel 221 surrounds the humidification top cover 220 and has multiple humidification holes 222 on its bottom surface that face the lower humidification filter 210. When the water in the second water tank 500 flows into the second water inlet 224 through the drain valve 510, it first enters the annular water channel 221, and then drips evenly onto the humidifying filter screen 210 through the humidification hole 222, thereby achieving the wetting and initial cleaning of the filter screen.
[0033] The humidification component 200 is the core module for achieving the humidification function. It includes a humidification top cover 220, a humidification filter 210, a support frame 230, and a support column 240. The humidification filter 210 is made of highly absorbent and breathable non-woven fabric or porous fiber material, possessing excellent water retention and antibacterial properties, effectively evaporating moisture into the airflow. This filter is fitted around the outer periphery of the support frame 230, which has a cylindrical structure. Its upper and lower ends are fixedly connected to the top surface of the humidification top cover 220 and the first water tank 300, respectively, ensuring the stability of the overall structure. The support column 240 is located at the center of the support frame 230, and its upper and lower ends are also connected to the top surface of the humidification top cover 220 and the first water tank 300, respectively. It not only provides reinforcement but also serves as a water pipe channel inside. Specifically, the water supply pipe corresponding to the first water inlet 223 connecting the first water tank 300 and the humidification top cover 220 is installed in the support column 240, which saves space and avoids exposed pipes from affecting aesthetics and safety.
[0034] The first water tank 300 is located directly below the humidification component 200. It has an overall annular or cylindrical hollow structure, with the hollow portion forming the main airflow channel. In traditional equipment, water tanks are mostly solid containers, occupying a large amount of vertical space. This invention "hollows out" the first water tank 300, creating an internal channel for airflow, and at least partially embeds the first fan 400 within this channel. This reduces the height space occupied by the fan, significantly improving vertical space utilization and compressing the overall height of the unit. The side wall of the first water tank 300 has a groove 320, within which a first water pump 321 is installed. One end of the pump is connected to the first water tank 300 via a water pipe, and the other end is connected to the first water inlet 223 on the humidification top cover 220 via a water pipe passing through a channel within the support column 240. When the equipment is running, the first water pump 321 pumps water from the first water tank 300 to the annular water channel 221, continuously supplying water to the humidification filter 210 and maintaining a stable humidification effect.
[0035] It is worth noting that this invention employs a dual-tank water supply mechanism, greatly improving ease of use and system reliability. Under normal operating conditions, the first water tank 300 serves as the main water source, continuously circulating water through the first water pump 321; while the second water tank 500 serves as an auxiliary water source, primarily used for rapid water replenishment or executing a self-cleaning procedure. When the user finds the water level in the first water tank 300 to be low, they can directly remove the top of the second water tank 500 to add water without shutting down the equipment, as the first water tank 300 still contains sufficient water to maintain humidification operation. After adding water, the second water tank 500 is reinstalled, and the drain valve 510 is opened. The clean water inside flows through the humidifying filter 210 under gravity, rinsing away dust, calcium and magnesium deposits adhering to the filter surface, achieving a self-maintenance function of "cleaning while operating." This process not only extends the service life of the humidifying filter 210 but also avoids decreased humidification efficiency or odor caused by filter clogging.
[0036] A first purification filter 600 is also installed around the humidification component 200. This filter is detachably installed on the outside of the humidification component 200 and is usually a pre-filter or composite filter material. It is used to intercept larger particles in the air (such as hair, dust, etc.) to prevent them from entering the humidification filter 210 and causing pollution. Since it is located as the first barrier before the airflow enters the humidification area, it is designed to be detachable. Regularly replacing or cleaning this filter can effectively protect the internal humidification system and improve the overall hygiene level.
[0037] More importantly, this invention features an independent purification component 700 at the bottom of the device to significantly enhance air purification capabilities. This purification component 700 is located below the first water tank 300 and physically isolated from the humidification duct, preventing moisture from entering the main purification system. The purification component 700 includes a second fan 720 and a second purification filter 710, with the second purification filter 710 positioned on both sides of the second fan 720, forming a "sandwich" structure. Air enters through the second air inlet 130 at the bottom of the housing 100, undergoes preliminary filtration by the second purification filters 710 on both sides, is then drawn in and accelerated by the second fan 720, and finally exits from the second air outlet 140. The second purification filter 710 can be a HEPA high-efficiency filter, activated carbon filter, or composite filter, effectively removing harmful substances such as PM2.5, formaldehyde, TVOC, bacteria, and viruses.
[0038] Specifically, the axis of the second fan 720 is perpendicular to the axis of the first fan 400 above it. For example, the first fan 400 is a vertical axial fan, while the second fan 720 is a horizontal axial fan. This orthogonal arrangement not only optimizes the internal space allocation but, more importantly, achieves complete separation of the humidifying airflow and the purifying airflow. The two airflows do not interfere with each other, effectively preventing moisture from entering the HEPA filter and causing it to become damp and ineffective or grow mold, thus ensuring the stability of its long-term purification performance.
[0039] In summary, this invention has successfully constructed an air purifier with humidification function that is compact, powerful, easy to operate, and reliable by designing the first water tank 300 as a hollow structure and embedding the first fan 400, adopting a novel airflow path with air intake in the middle and air outlet at the bottom, setting a top-removable second water tank 500 to achieve water replenishment without stopping the machine and self-cleaning of the filter, and configuring an independently orthogonally arranged purification component 700 at the bottom.
