[0030] See also Figures 2 to 4In one embodiment provided in the present application, a humidifier 100 is used to humidify air using liquid water in a water tank 60. The humidifier 100 includes a housing 10, an airflow generating device 20, a water pump device 30, and a water film mechanism 40. The housing 10 has a receiving space 11, an air inlet 12, and an air outlet 13, and the air inlet 12 and the air outlet 13 are respectively connected to the receiving space 11. The airflow generating device 20 is arranged in the receiving space to drive the airflow in the receiving space 11 to flow out through the air outlet 13, and the water pump device 30 is installed in the housing 10 and is used to be connected to the water tank 60.

By setting the water film mechanism 40 and the water pump device 30, the water pump device 30 is used to pump liquid water to the water film mechanism 40 and then flow out, and form gaseous water under the action of airflow. On the one hand, it is unnecessary to set up the existing wet curtain assembly, which can save production cost and use cost, reduce the steps of replacing consumables, and improve the user's convenience. On the other hand, it can avoid the generation of dust, odor, and bacteria, effectively prevent the problem of indoor environment being polluted by dust and bacteria in water due to humidification, and improve the humidification effect. In addition, the structure of the water film mechanism 40 is simple and easy to clean and install. Further, the humidifier 100 is also provided with an airflow generating device 20, which can improve the humidification efficiency by driving and accelerating the flow rate of gaseous water and air using the airflow generating device 20.

[0031] Next, each component of the humidifier 100 and the specific structure of each component will be introduced one by one.

[0032] See also Figure 1 and Figure 2 In this embodiment, the shell 10 is used to install and protect the components. Specifically, the shell 10 has a receiving space 11, and the receiving space 11 is used to install and place the components. The components may be the airflow generating device 20, the water pump device 30, the water film mechanism 40, the sink or other components mentioned above. In some embodiments, when the sink or water tank 60 is arranged inside the shell 10, the shell 10 is also used to support the use place of the humidifier 100, for example, the ground, a desktop or other supporting platform. The material of the shell 10 may include high-strength, impact-resistant plastic materials and metal materials, which can protect the internal components from external damage.

[0033] As an example, the outer contour of the housing 10 is roughly cylindrical, and the material of the housing 10 may include ABS plastic, PC plastic or other hard plastic, which can not only reduce the weight of the housing 10 to achieve lightweight, but also enable the housing 10 to have a certain stability, thereby effectively protecting the components inside the housing 10. On the other hand, the plastic material has the characteristics of low cost, good plasticity, easy processing, and not easy to break, which can reduce the production cost of the humidifier 100. It should be noted that the material of the housing 10 can also be ceramic material, glass material or other material, which is not limited in this embodiment.

[0034] In this embodiment, the shell 10 also has an air inlet 12 and an air outlet 13, and the air inlet 12, the air outlet 13 and the storage space 11 are connected. Specifically, the shell 10 includes a top wall 102 and a surrounding wall 101, the top wall 102 is connected to one end of the surrounding wall 101 and defines the storage space 11 together with the surrounding wall 101, the air outlet 13 is arranged on the top wall 102, and the air inlet 12 is arranged on the surrounding wall 101. When the humidifier 100 is working normally, the outside air enters the storage space 11 through the air inlet 12 along the second direction and is soaked by the water film mechanism 40, and then flows from the air outlet 13 along the first direction to the outside. The above-mentioned "first direction" can be understood as the gravity direction when the humidifier 100 is placed in normal use, that is, the axial direction of the humidifier 100. The "second direction" can be understood as the radial direction when the humidifier 100 is placed normally, and the second direction intersects with the first direction. As an example, the air inlet 12 can be arranged around the peripheral wall 101, so that the peripheral wall 101 becomes an air inlet area, and the air outlet 13 can cover the top wall 102, thereby improving space utilization and improving airflow exchange efficiency.

[0035] In this embodiment, the airflow generating device 20 is arranged in the accommodating space 11, which is used to drive the airflow and gaseous water to flow to the outside through the air outlet 13, so as to realize environmental humidification. Specifically, the airflow generating device 20 is arranged in the interval area formed by the air outlet 13 and the water film mechanism 40, and the airflow generating device 20 has an air inlet side 21 and an air outlet side 22, the air inlet side 21 is arranged toward the water film mechanism 40, and the air outlet side 22 is arranged toward the air outlet 13. After the outside air enters the accommodating space 11 through the air inlet 12 and contacts the water film mechanism 40, the airflow generating device 20 drives the air to move from the air inlet side to the air outlet side, and then flows to the outside through the air outlet 13. The airflow generating device 20 may include a driving motor (not shown in the figure) and a fan blade assembly (not shown in the figure), the fan blade assembly is connected to the driving motor, and the rotation speed of the fan blade assembly is controlled by controlling the output power of the driving motor, thereby controlling the working efficiency of the humidifier 100. In some embodiments, the humidifier 100 may further include an airflow guiding structure (not shown in the figure), which is used to guide the flow direction of the airflow and the water mist and improve the utilization rate of the airflow and the water mist. The airflow guiding device may be a guide plate, a guide pipe, etc., which is not limited in this embodiment. As an example, the airflow guiding structure may be a guide pipe, which is detachably connected to the airflow generating device 20 for easy maintenance and replacement.

[0036] See also Figures 2 to 4 In this embodiment, the water film mechanism 40 is arranged in the accommodation space 11, and the water film mechanism 40 is used to make liquid water flow out and form a water film. The water film mechanism 40 is connected to the water pump device 30, and the water pump device 30 is installed in the housing 10 and connected to the water tank 60. The water pump device 30 pumps the liquid water in the water tank 60 to the water film mechanism 40 to maintain the normal operation of the humidifier 100. Specifically, the water film mechanism 40 is provided with a connected water guide channel 41 and a water outlet channel 42, the water guide channel 41 is connected to the water pump device 30, and the water outlet channel 42 is connected to the accommodation space 11. Liquid water flows in the water guide channel 41 and flows out through the water outlet channel 42 to form a water film. When the outside air can pass through or flow through the water film, water molecules evaporate from the water film and enter the air, which can increase the humidity of the air. On the one hand, the water film mechanism 40 in the embodiment of the present application does not need to be provided with a conventional wet curtain assembly, which can save production cost and use cost, reduce the steps of replacing consumables, and improve the user's convenience. On the other hand, the water film formed by the water film mechanism 40 is also used to filter dust and particles in the air, which can avoid odor and bacteria caused by untimely replacement or improper cleaning of conventional wet curtain components, effectively prevent the indoor environment from being polluted by dust and bacteria in the water due to humidification, and improve the humidification effect. In addition, since liquid water can flow in the water guide channel 41, the possibility of bacterial and mold growth can be further reduced.

[0037] Specifically, the water film mechanism 40 includes a water film pipe 43, the internal space of the water film pipe 43 defines the above-mentioned water guide channel 41, and the water film pipe 43 is used to form a water film. The water film pipe 43 has a first end 431 and a second end 432 spaced apart, the first end 431 is connected to the water pump device 30, and the second end 432 is closed. The water film pipe 43 extends from the first end 431 to the second end 432, and the water outlet channel 42 is arranged between the first end 431 and the second end 432, so as to prevent liquid water from leaking from the second end 432, and ensure the stability of the water film formation. The material of the water film pipe 43 can be plastic, cast iron, glass fiber and other materials, which are not limited in this embodiment.

[0038] In this embodiment, the water film pipeline 43 includes a plurality of pipes 433, and the plurality of pipes 433 are connected in sequence. Each pipe 433 is provided with a water outlet channel 42, so that liquid water flowing through each pipe 433 can flow out from the corresponding water outlet channel 42 to form a corresponding water film area. In order to form as many water film areas as possible, at least part of the structure of two adjacent pipes 433 is arranged at intervals from each other, so that the water film areas corresponding to the two adjacent pipes 433 are spaced from each other. As an example, a plurality of pipes 433 are connected in sequence and arranged in a spiral shape in the accommodation space 11, so that the plurality of water film areas formed are spaced from each other and spirally surrounded, so that more water films can be formed in a smaller installation space, increasing the surface area of ​​the water film in contact with the air, which is conducive to improving the humidification efficiency of the humidifier 100 and reducing the overall volume of the humidifier 100. In addition, the spiral surrounding also helps to increase the path length of the liquid water flowing through the water film pipeline 43, so that the water molecules have more time to evaporate into the air. As another example, multiple tubes 433 are connected in sequence and arranged in a folded line in the accommodating space 11, so as to form multiple water film areas arranged in sequence. It is understandable that the arrangement between the multiple tubes 433 is not limited to the spiral winding and folded line winding mentioned above, and can also be a wavy arrangement, overlapping arrangement or other forms of arrangement, which is not limited in this embodiment. By increasing the surface area of ​​the water film and providing more disturbances for the air flow, the evaporation of liquid water is promoted, thereby improving the humidification efficiency.

[0039] In this embodiment, in order to facilitate the liquid water to flow out of the water film pipe 43 to form a water film, the water outlet channel 42 can be located below the gravity direction of the water film pipe 43. As an example, the water outlet channel 42 can be a microporous structure, which penetrates the pipe wall on the side below the gravity direction of the water film pipe 43 and is connected to the water guide channel 41. A plurality of microporous structures are arranged from the first end 431 to the second end 432 of the water film pipe 43 at intervals from each other, thereby forming a planar or linear water film. The pore diameter of the microporous structure and the spacing between adjacent microporous structures can be set according to actual needs. As an example, the pore size of the microporous structure can range from 0.4mm to 1.5mm (including the end points), for example, the pore size of the microporous structure can be 0.4mm, 0.6mm, 1mm, 1.5mm, etc. The spacing between adjacent microporous structures can range from 0.4mm to 1.5mm (including the end points), for example, the spacing between two adjacent microporous structures can be 0.4mm, 0.6mm, 1mm, 1.5mm, etc. It should be noted that the pore size of the microporous structure and the spacing between adjacent microporous structures can also be other values. The number of microporous structures is not limited in this embodiment. It can be understood that the more microporous structures there are, the denser the water film area formed, and the better the humidification effect.

[0040] As another example, the water outlet channel 42 may be a water flow gap, which is arranged to penetrate the tube wall on one side below the gravity direction of the water film pipe 43 and is connected to the water guide channel 41, and liquid water flows out through the water flow gap to form a planar water film. Specifically, the water flow gap is arranged from the first end 431 to the second end 432 of the water film pipe 43. The gap width of the water flow gap may range from 0.4 mm to 1.5 mm (including the end points), for example, the gap span width of the water flow gap may be 0.4 mm, 0.6 mm, 1 mm, 1.5 mm, etc. As another example, the water outlet channel 42 may be a collection of water flow gaps and microporous structures, and the microporous structure may be arranged at the junction of the water flow gap and the water film pipe 43, so as to expand the water outlet area and improve the working efficiency of the humidifier 100.

[0041] In this embodiment, two adjacent water film areas are spaced apart to form an airflow channel 44, and external air or gaseous water can move to the air outlet 13 via the airflow channel 44. Specifically, the extension direction of the airflow channel 44 is the same as the extension direction of gravity, and the extension direction of the air outlet 13 is the same as the extension direction of the airflow, which can reduce the resistance of air flow and water mist flow, ensure that the airflow flows smoothly in the housing 10, and thus improve the working efficiency of the humidifier 100.

[0042] In order to further improve the humidification efficiency of the humidifier 100, the humidifier 100 also includes a heating device 50. The heating device 50 is connected between the water pump device 30 and the water film mechanism 40. The heating device 50 is used to heat the water in the water tank 60 to form hot water. The hot water can increase the evaporation of water molecules, thereby improving the humidification efficiency. Specifically, the water pump device 30 draws liquid water from the water tank 60 into the heating device 50 to heat and form hot water, and the hot water flows to the water film mechanism 40 to form a water film. Hot water can accelerate the process of liquid water being converted into gaseous water, thereby improving the humidification effect. In addition, when the temperature of the hot water is high, it can play a sterilizing role and improve the humidification quality of the humidifier 100. In this embodiment, the heating device 50 can be a PCT ceramic heating element, a metal electric heating tube or an electric heating wire heating element, etc., and this embodiment does not specifically limit this. As an example, the heating device 50 is a PCT ceramic heating element. The PCT ceramic heating element has the characteristics of low thermal resistance and high heat exchange efficiency. It can generate heat quickly in a short time and can improve the working efficiency of the humidifier 100.

[0043] See also Figure 2 In this embodiment, the humidifier 100 also includes a water tank 60, which is used to store liquid water and installation components. The water tank 60 is detachably connected to the housing 10, which is convenient for the user to add water to the water tank 60. In order to improve the portability of the humidifier 100, the material of the water tank 60 can be ABS plastic, PC plastic or other hard plastic. This can not only reduce the weight of the water tank 60 to achieve lightweight and easy disassembly and installation, but also enable the water tank 60 to have a certain stability, thereby effectively protecting the installation components inside the water tank 60. On the other hand, the plastic material has the characteristics of low cost, good plasticity, easy processing, and not easy to break, which can reduce the production cost of the humidifier 100. It should be noted that the material of the box body 10 can also be other metal materials such as aluminum, stainless steel, copper, etc., and this embodiment does not limit this.

[0044] In the present embodiment, the water tank 60 is arranged below the housing 10 in the direction of gravity and is supported on the use platform. By arranging the water tank 60 at the lower part of the housing 10, the center of gravity of the humidifier 100 can be lowered, and the vibration generated during the operation of the airflow generating device 20 can be reduced, thereby increasing stability. At the same time, the bottom water tank 60 has a large water storage volume, which can meet the requirements of large-capacity humidification. In some embodiments, the water tank 60 can also be provided with water inlet holes, so that the water replenishment requirements can be met without removing the housing 10, thereby improving the user's convenience. It should be noted that in other embodiments, the water tank 60 can be arranged inside the housing 10, so that the overall volume of the humidifier 100 is more compact.

[0045] In this embodiment, the water tank 60 has a accommodating chamber 61, and the opening of the accommodating chamber 61 faces the accommodating space 11. The accommodating chamber 61 is used to store water and accommodate installation components. The humidifier 100 also includes a partition plate 70, which is used to cover the accommodating chamber 61 and separate the accommodating chamber 61 and the accommodating space 11. In this embodiment, a water droplet 71 can be opened on the partition plate 70, and the water droplet 71 penetrates the partition plate 70 and communicates with the accommodating space 11 and the accommodating chamber 61. When the humidifier 100 is working normally, the liquid water discharged from the water film mechanism 40 and the condensed gaseous water can fall back to the water tank 60 from the water droplet 71, which can improve the recycling rate of water on the one hand. On the other hand, it can prevent excessive water from being retained in the accommodating space 11 for a long time, thereby avoiding the generation of bacteria and mold, and improving the humidification effect of the humidifier 100. It should be noted that the specific installation position and caliber size of the water droplet 71 are not limited in this embodiment.

[0046] In order to improve the quality of circulating water, the humidifier 100 may also include a dirt-blocking cover (not shown in the figure), which is arranged in the accommodating space 11 and covers the water outlet 71, and is used to intercept impurities in the water. The dirt-blocking cover is also provided with a plurality of microstructures (not shown in the figure), which are used to intercept fine particles of impurities in the water, so that the water is further purified and the turbidity of the water is reduced. At the same time, organic matter and bacteria in the water are removed in large quantities as the turbidity decreases, thereby providing good water quality conditions. In addition, the dirt-blocking cover also plays a role in buffering water pressure, which can reduce the impact of water flow and improve drainage stability. In other embodiments, a filter net can also be provided in the dirt-blocking cover, and the impurity particles can be further intercepted by providing the filter net, thereby further improving the quality of circulating water. It should be noted that the number of filter nets can be a single-layer mesh structure or a multi-layer mesh structure, and the filter apertures of different filter nets can be different, so as to filter impurities in a targeted manner and improve the filtering effect.

[0047] Since the water outlet 71 and the bottom wall 62 of the water tank 60 have a certain height, the accumulated water is easy to produce water sound and noise when draining through the water outlet 71. The humidifier 100 can also include a water pipe 80, which is used to reduce the impact speed of the water flow and reduce the water flow impact and splashing phenomenon, thereby achieving the purpose of reducing noise. Specifically, the water tank 60 has a bottom wall 62 and a surrounding side wall 63. The side wall 63 is connected to the housing 10, and the bottom wall 62 is arranged on the side of the side wall 63 away from the partition plate 70. The side wall 63, the bottom wall 62 and the partition plate 70 jointly define the accommodating chamber 61, and the water pipe 80 is arranged in the accommodating chamber 61 and connected to the outer periphery of the water outlet 71. In order to facilitate silencing, the water pipe 80 can extend from the partition plate 70 to the bottom wall 62, and the water flow can flow along the inner wall of the water pipe 80, avoiding the water flow from directly impacting the bottom wall 62 at a higher height, thereby reducing the water sound and noise. As an example, the distance between the end of the water pipe 80 and the bottom wall 62 has a value range of 0 mm to 10 mm (including the end points), for example, the distance between the end of the water pipe 80 and the bottom wall 62 can be 0 mm, 1 mm, 5 mm, 10 mm, etc. It should be noted that the distance between the end of the water pipe 80 and the bottom wall 62 can also be other values, which can be set according to actual application requirements, so as to reduce the sound of water and noise in the water pipe, which is not limited in this embodiment.

[0048] In this embodiment, the water conduit 80 can also be provided with a water outlet 81 on the pipe wall. Specifically, the water conduit 80 has a first connection end 82 and a second connection end 83, and the first connection end 82 and the second connection end 83 are separated. The first connection end 82 is used to connect the downspout 71, and the second connection end 83 is extended near the bottom wall. The water conduit 80 has a pipe wall and a pipe bottom wall, and the pipe wall is suitable for being parallel and spaced with the side wall 63 of the water tank 60, and the pipe bottom wall is suitable for being parallel and spaced with the bottom wall 62 of the water tank 60. The water outlet 81 is arranged at the second connection end 83 and is located on the pipe wall, and specifically, the water outlet 81 is arranged along the radial direction of the pipe wall and penetrates the pipe wall. By arranging the above-mentioned water outlet 81, it is possible to avoid the water flow directly toward the bottom wall 62, and reduce the sound and noise of the water flow directly impacting the bottom wall 62. In some embodiments, the number of the water outlets 81 can be multiple, and the multiple water outlets 81 are spaced from each other and arranged on the periphery of the pipe wall. The water flows out from different water outlets 81, which can achieve uniform distribution of the water flow, thereby reducing water flow impact and noise. At the same time, the water flow is dispersed to different water outlets 81, which can reduce the impact speed and effectively reduce the sound and noise of the water.

[0049] In some embodiments, in order to further reduce the sound of water flowing and noise generated by the water outlet, the humidifier 100 also includes a sound-absorbing material (not shown in the figure). As an example, the sound-absorbing material can be a soft lining, such as a rubber pad, foam, etc. The soft lining is arranged inside the water pipe 80 to absorb the sound of water flowing and noise during the flow of water. As another example, the sound-absorbing material can also be sound-absorbing cotton or sound-proof foam, and the sound-absorbing material is wrapped around the outer wall of the water pipe 70 to isolate the propagation of noise. In some embodiments, in order to improve the connection sealing performance between the water pipe 70 and the drain outlet 71, a seal (not shown in the figure) can also be provided at the first connection end 82. The seal can be a rubber ring, a sealant, a sealing pad, etc., which is not limited in this embodiment.

[0050] In this embodiment, since the water pump device 30 also generates certain noise during the suction process, the humidifier 100 may further include a connector 90. As an example, a water pipe 64 is provided in the water tank 60, and the water pipe 64 is connected to the water pump device 30. The water pipe 64 can extend to the bottom wall 62 of the water tank 60, so as to facilitate the water pump device 30 to pump water. The connector 90 is connected to the water pipe 64, and the connector 90 has a third connecting end 91 and a fourth connecting end 92 that are separated from each other. Specifically, the third connecting end 91 is used to connect the water pipe 64, and the fourth connecting end 92 is connected to the bottom wall 62, and plays a certain supporting role. The connector 90 has a peripheral wall, and the peripheral wall is suitable for being arranged in parallel with the side wall 63 of the water tank 60. A water inlet 93 is provided on the fourth connecting end 92 and is located on the peripheral wall, and specifically, the water inlet is arranged to penetrate along the radial direction of the peripheral wall of the connector 90. As an example, the vertical distance between the water inlet 93 and the bottom wall 62 is less than the vertical distance between the water outlet 81 and the bottom wall 62. By setting the above-mentioned water inlet 93, the noise generated by the water flow impacting the end of the connector 90 can be reduced, providing the user with a quieter humidification environment. At the same time, it can be improved. In some embodiments, the number of water inlets 93 can be multiple. Multiple water inlets 93 are spaced apart from each other and arranged in sequence along the peripheral wall. On the one hand, the water inlet area can be increased, thereby improving the working efficiency of the humidifier 100. On the other hand, the uniformity of water inlet can be improved, the generation of end flow and eddy current can be reduced, thereby reducing energy consumption. In other embodiments, a filter screen (not shown in the figure) can be set at the water inlet 93, and the impurities in the water can be filtered out by setting the filter screen, thereby providing a good liquid environment. The number of filter screens and the filter aperture are not limited in this embodiment.

[0051] In order to reduce the noise generated during the process of water flow being sucked into the water film mechanism 40, in some embodiments, a sound absorbing material may also be arranged at the water pipe. As an example, the sound absorbing material is arranged inside the water pipe 64 to absorb the sound of water and noise during the flow of water. As another example, the sound absorbing material is wrapped around the outer wall of the water pipe 64 or arranged at the water inlet 93, thereby reducing the propagation of noise.

[0052] In summary, a humidifier 100 provided in an embodiment of the present application includes a housing 10, an airflow generating device 20, a water pump device 30, and a water film mechanism 40. By setting the water film mechanism 40 and the water pump device 30, the water pump device 30 is used to suck liquid water to the water film mechanism 40 and then flow out, and gaseous water is formed under the action of the airflow. Specifically, the water film mechanism 40 is provided with a water guide channel 41 and a water outlet channel 42 that are interconnected, and the water guide channel 41 is connected to the water pump device 30, and the liquid water is sucked to the water guide channel 41 and then discharged from the water outlet channel 42. On the one hand, the above-mentioned setting does not need to set up the existing wet curtain assembly, which can save production cost and use cost, reduce the steps of replacing consumables, and improve the user's convenience. On the other hand, it can avoid the generation of dust, odor, and bacteria, effectively prevent the problem of humidification causing the indoor environment to be polluted by dust and bacteria in the water, and improve the humidification effect. In addition, the structure of the water film mechanism 40 is simple and easy to clean and install. Furthermore, the humidifier 100 is also provided with an airflow generating device 20 , and the humidification efficiency can be improved by utilizing the airflow generating device 20 to drive and accelerate the flow speed of gaseous water and air.
