Description

Technical Field

[0001] This invention relates to the field of humidifier technology, and in particular to a mist-free humidifier with a water film curtain core structure. Background Technology

[0002] The principle of a mist-free humidifier is to humidify the environment by blowing water from a wet curtain into the external environment through airflow. This type of humidifier uses a water pump to draw water from the tank to the top of the wet curtain for humidification. When the wet curtain or filter is saturated, excess water flows back to the tank at the bottom, and the pump circulates the water to the wet curtain again. However, existing wet curtains are generally made of absorbent cotton, fabric, or paperboard, which are prone to cracking after prolonged soaking. To ensure the humidifier's effectiveness, and because bacteria can easily grow inside the wet curtain, which is dispersed into the air along with the moisture as the fan blows, potentially affecting the user's health, the wet curtain needs to be replaced frequently. This results in high production and maintenance costs and a relatively complex manufacturing process. Summary of the Invention

[0038] Example

[0039] Reference Figures 1 to 10 The present invention proposes a mist-free humidifier with a water film curtain core structure, comprising: a water storage chamber 22, a control center 30, a wet curtain structure 40, and a fan assembly 50 and a circulating water pump assembly 70 electrically connected to the control center 30. The circulating water pump assembly 70 can guide the water in the water storage chamber 22 to the wet curtain structure 40, and the fan assembly 50 is used to drive air to flow through the wet curtain structure 40.

[0040] The wet curtain structure 40 includes a water film curtain assembly 41; the water film curtain assembly 41 is a rigid, non-absorbent component; the upper and lower ends of the water film curtain assembly 41 are the water inlet and water outlet respectively, and the water film curtain assembly 41 is provided with air supply channels 42 on both sides along the thickness direction.

[0041] In this invention, the water film curtain assembly 41 is made of rigid, non-absorbent material such as plastic or metal. As water flows from the upper part to the lower part of the assembly, a water film forms along the vertical wall or horizontal plate. Under the suction of the fan assembly 50, this forms high-humidity, fog-free air rich in water vapor, which is then expelled to the outside. The rigid water film curtain assembly 41 can be quickly cleaned by rinsing after removal and then reinstalled in the humidifier for reuse, eliminating the need for frequent replacements. This significantly extends the service life of the wet curtain structure 40 and effectively reduces maintenance costs. Furthermore, the plastic water film curtain assembly 41 can be integrally injection molded, greatly simplifying the production process and reducing production costs.

[0042] In addition to using easily injection-molded plastic parts or cast metal parts, the water film curtain assembly 41 can also be made of ceramic parts. Preferably, the water film curtain assembly 41 is made of injection-molded plastic parts.

[0043] In some embodiments, the water film curtain assembly 41 includes several curtain cores 411 stacked one on top of the other. Each curtain core 411 is a small, individual component. Considering the structure of the air supply channel 42 extending along its thickness direction, stacking several small curtain cores 411 into the water film curtain assembly 41 significantly reduces the size of a single injection-molded part and facilitates the creation of corresponding molds for production. Furthermore, by stacking the curtain cores 411, the overall height of the water film curtain assembly 41 can be flexibly adjusted by the manufacturer. By simply changing the lateral dimension of a single curtain core 411, water film curtain assemblies 41 with various lateral dimensions and vertical heights can be matched and combined to adapt to various specifications of mist-free humidifier products, significantly reducing production costs and the types of materials required.

[0044] In this embodiment, the manufacturer can flexibly adjust the air supply channel 42 of the curtain core component 411 according to the design style. For example, in some embodiments, the curtain core component 411 is provided with an independent air supply channel 42. Preferably, in other embodiments, two adjacent curtain core components 411 are stacked to form an air supply channel 42, which can reduce the air duct wall surface of the curtain core component 411, simplify the structure of the curtain core component 411, reduce costs, and facilitate production.

[0045] There are two common types of mist-free humidifiers on the market. One type has the air inlet and outlet located on the outside of the base shell, with the fan positioned between them. The fan blades blow air forward, creating an airflow from the air inlet to the outlet that passes through the wet curtain structure 40. It features a horizontally arranged airflow channel and is typically a flat, box-shaped structure. The other type has a vertical cylindrical structure, with the air inlet located on the side of the base 10 and the air outlet located on the top of the base 10. The fan assembly 50 blows air outward within the blower chamber 12, creating an upward airflow. This type of humidifier has a vertically stacked structure consisting of several components with a vertical airflow channel. This type of product has a more aesthetically pleasing appearance and higher user acceptance. However, the overall stacked structure places higher demands on the design and arrangement of the wet curtain structure 40 and its components.

[0046] To match the vertical cylindrical mist-free humidifier structure, in this embodiment, the water film curtain assembly 41 is arranged in a cylindrical shape, and the curtain core 411 is arranged in a ring shape. The air inlet of the vertical cylindrical mist-free humidifier is generally arranged around the outer periphery of the base shell, and the water curtain structure is spaced inside the ring-shaped air inlet. To match the arrangement, the water film curtain assembly 41 can be correspondingly arranged in a vertical cylindrical shape, and the curtain core 411 is arranged in a ring shape. The outer side of the water film curtain assembly 41 is the air inlet end of the air supply channel 42, and the inner side of the water film curtain assembly 41 is the air outlet end of the air supply channel 42.

[0047] Specifically, the water film curtain assembly 41 can be configured as a polygonal cylindrical structure with a cross-section of a triangle, square, regular hexagon, or a cylindrical structure with an arc shape; correspondingly, the curtain core 411 is arranged in a polygonal annular structure with a triangle, square, regular hexagon, or an annular structure with an arc shape.

[0048] In this embodiment, the curtain core component 411 includes a water film substrate 4111; the water film substrate 4111 is provided with water passage holes 4112 and water distribution plates 4113; one end of the water distribution plate 4113 is fixed to the substrate, and the other end can abut against the water film substrate 4111 of another curtain core component 411. The curtain core component 411 consists only of a horizontally arranged water film substrate 4111 and a vertically arranged water distribution plate 4113. By stacking them, an air supply channel 42 can be formed. At the same time, the water passage holes 4112 can be used to guide water from the upper curtain core component 411 to the lower curtain core component 411. The overall structure is simple, and the curtain core component 411 is easy to manufacture.

[0049] Specifically, in order to make the water film formed by the water film curtain assembly 41 more uniform, the water passage holes 4112 are evenly spaced on the water film substrate 4111; the water separating plates 4113 are evenly spaced on the water film substrate 4111.

[0050] Furthermore, a water passage hole 4112 is provided between two adjacent water distribution plates 4113. This water passage hole 4112 allows both water distribution plates 4113 on both sides to be wetted by water flow, resulting in a more uniform water film and reducing the likelihood of gaps.

[0051] In some embodiments, at least two sets of water passage holes 4112 and water dividers 4113 are provided, and the at least two sets of water passage holes 4112 and water dividers 4113 are spaced apart on the water film substrate 4111 along the thickness direction of the water film curtain assembly 41. The two sets of water passage holes 4112 and water dividers 4113 arranged at intervals along the thickness direction of the water film curtain assembly 41, that is, the radial direction of the cylindrical water film curtain assembly 41, are distributed at intervals corresponding to the extension direction of the air supply channel 42. Air can sequentially contact the water film formed by each set of water dividers 4113 in the air supply channel 42. By contacting the water film of the multiple sets of water dividers 4113, the contact area between air and water film can be increased, the amount of water carried by the airflow can be increased, and the humidification performance can be improved.

[0052] In this embodiment, the water film curtain assembly 41 further includes a curtain mounting frame 43 and a curtain top cover 44; several curtain cores 411 can be stacked and placed inside the curtain mounting frame 43; the curtain top cover 44 is detachably installed on the top of the curtain mounting frame 43 and can cover several curtain cores 411. To facilitate the stacking and arrangement of the curtain cores 411 to form the water film curtain assembly 41, the curtain mounting frame 43 is a hollow frame structure with several connecting posts on the outside that can abut against the outer edge of the curtain cores 411; a reinforcing ring rib structure is provided in the middle. In actual use, the curtain cores 411 are simply placed one by one into the integrated mounting frame, and then the curtain top cover 44 is fastened to the top of the curtain mounting frame 43 to complete the assembly. Both the curtain top cover 44 and the curtain mounting frame 43 are provided with water passage holes 4112.

[0053] Specifically, the curtain top cover 44 and the curtain mounting bracket 43 can be connected by a detachable connection method such as a snap-fit ​​or bolt / screw connection.

[0054] Outside air typically carries dust and bacteria. This type of spraying can easily cause dirt to accumulate in the bottom water tank, resulting in unsanitary humidified air. Therefore, patent number CN202221384964.7 proposes a clean and wastewater separation type of mist-free humidifier. It utilizes two separate water tanks, a main storage tank and a secondary working circulating water tank, separating the circulating water from the water in the storage tank. This structure makes the humidified air produced by the humidifier cleaner and more hygienic. The disinfection and hygiene performance of humidifiers have always been a key focus for customers and manufacturers.

[0055] Considering that replacing soft absorbent cotton, curtains, or paperboard with the rigid non-absorbent material of this invention, although the wet curtain itself is not easy to adsorb residual bacteria, its ability to purify and disinfect the air is weakened. Therefore, it is necessary to consider a more comprehensive and efficient disinfection and purification structure to ensure the purification and disinfection performance of the humidified air.

[0056] This invention also proposes a mist-free humidifier solution that utilizes the water film curtain core structure of this invention, offering superior disinfection performance and maintaining cleanliness and hygiene. Please refer to [link / reference]. Figures 4 to 10 The details are as follows:

[0057] In this embodiment, the mist-free humidifier also includes a base 10, a water tank assembly 20, and a water discharge control assembly 60;

[0058] The base 10 is provided with a water curtain chamber 11, a blower chamber 12 and a bottom water tank 13; the wet curtain structure 40 is installed in the water curtain chamber 11 and the fan assembly 50 is installed in the blower chamber 12; the water tank assembly 20 is provided with a water storage chamber 22; the drain control assembly 60 can supply water from the water storage chamber 22 to the wet curtain structure 40; the bottom water tank 13 can collect water flowing out of the wet curtain structure 40 and can circulate water to the wet curtain structure 40 through the circulating water pump assembly 70.

[0059] The fan assembly 50 creates a negative pressure airflow, causing outside air to pass through the wet curtain structure 40 of the water curtain chamber 11, forming high-humidity, fog-free air rich in water vapor. This air is then drawn into the blower chamber 12 and subsequently discharged through the mist outlet above the base 10. The bottom water tank 13 serves as a second water tank, with water circulating to the wet curtain. It is separated from the water storage chamber 22 within the water tank assembly 20. The working circulating water is kept separate from the water in the storage chamber 22, making the humidified, fog-free air generated by the humidifier cleaner and more hygienic.

[0060] In a preferred embodiment, the mist-free humidifier also includes a filter assembly 90 and a heating plate 80; a drain outlet 21 is provided below the water tank assembly 20; the drain outlet 21 is connected to the drain control assembly 60, and the water inlet end of the drain outlet 21 is provided with the filter assembly 90; a heating plate 80 is provided in the bottom water tank 13, and the heating plate 80 can heat the water in the bottom water tank 13.

[0061] A filter assembly 90 is installed at the water inlet of the drain outlet 21. When the humidification circulation is activated, the filter assembly 90 performs initial filtration of the water in the water tank. After the water is delivered above the evaporative cooling pad, it flows into the bottom water tank 13. The heating plate 80 heats the water in the bottom water tank 13, thus reheating and sterilizing the circulating humidification water. This also raises the water temperature, making it easier for the water inside the evaporative cooling pad to evaporate and be drawn out by the fan assembly 50. During the initial humidification operation and the circulation process, the mist-free humidifier undergoes multiple filtrations and sterilizations, improving its sterilization function and hygiene performance.

[0062] The filter assembly 90 includes a filter cartridge housing 91 and a filter cartridge; the filter cartridge is installed inside the filter cartridge housing 91, which is detachably installed in the water tank assembly 20. The detachable installation of the filter cartridge housing 91 in the water tank assembly 20 allows for easy removal of the filter assembly 90 for cleaning or replacement of the filter cartridge.

[0063] Specifically, the filter cartridge housing 91 includes a detachably connected upper filter cartridge cover 911 and a lower filter cartridge cover 912. The upper filter cartridge cover 911 and the lower filter cartridge cover 912 enclose a filter cartridge cavity 92, in which the filter cartridge is installed. The upper filter cartridge cover 911 and the lower filter cartridge cover can be positioned and locked using bolts, clips, or positioning pins. Furthermore, several water inlets are provided on the outer periphery of the upper filter cartridge cover 911 and the lower filter cartridge cover. The filter cartridge can be an integrated cotton core used in the prior art, or a commonly used filter cartridge element such as quartz sand or carbon particles placed inside the filter cartridge cavity 92.

[0064] In some embodiments, a drain connection cavity 93 is also provided inside the filter cartridge cavity 92; the drain connection cavity 93 is connected to the drain outlet 21; the water in the water tank assembly 20 needs to be filtered by the filter cartridge in the filter cartridge cavity 92 before it can reach the drain connection cavity 93 and be supplied to the drain control assembly 60.

[0065] Furthermore, the filter cartridge housing 91 is also provided with a filter cartridge connecting ring 913, which is located inside the drain connection cavity 93 and can be snapped onto and aligned with the drain outlet 21. The outer edge of the drain outlet 21 is provided with a positioning protrusion ring structure, and the bottom of the filter cartridge connecting ring 913 can be snapped onto the positioning protrusion ring structure, thereby aligning the filter assembly 90 with the drain outlet 21 for installation.

[0066] The drain control component 60 includes a water tank top rod 61, a drain valve seat 62, and an electric control valve 63. The drain valve seat 62 is located at the outlet end of the drain 21 and is connected to the electric control valve 63 via a pipeline. The water tank top rod 61 is installed on the drain valve seat 62 and can block the drain 21. When the humidifier starts humidifying, the solenoid valve opens the pipeline of the drain control component 60, and water is transferred to the filter element through the drain control component 60 under the action of gravity. After the bottom water tank 13 has collected enough water for circulation, the solenoid valve closes the pipeline of the drain control component 60, the water in the corresponding drain valve seat 62 stops flowing, and the drain 21 is blocked by the water tank top rod 61. The drain blocking structure of the water tank top rod 61 can be arranged according to existing technology and will not be described in detail here.

[0067] In some embodiments, the bottom water tank 13 includes an outer ring collection tank 131 and a central collection tank 132; the outer ring collection tank 131 is arranged around the outer periphery of the central collection tank 132 and can collect water flowing out of the wet curtain; a water passage 133 is provided between the outer ring collection tank 131 and the central lower water tank, and the heating plate 80 is disposed in the central collection tank 132. The bottom water tank 13 is divided into an outer ring collection tank 131 and a central collection tank 132, and water can flow from the outer ring collection tank 131 to the central collection tank 132 through the water passage 133, dividing the area into a water return collection area and a heating working area, so that functional elements can be better arranged in the corresponding areas.

[0068] Specifically, the outer ring collection tank 131 is equipped with a water level detection component 15, which can detect the water level of the outer ring collection tank 131 and feed it back to the control center 30. The water level monitoring component can detect the water level of the outer ring collection tank 131 to reflect the amount of circulating working water in the bottom water tank 13, and feed this data back to the control center 30 to coordinate the water discharge of the drainage control component 60 and the heating operation of the heating plate 80, so as to avoid excessive water discharge in the bottom water tank 13 or dry burning of the heating plate 80.

[0069] In some embodiments, a UV disinfection lamp 16 is provided on one side of the water passage 133. Since the outer ring collection tank 131 flows unidirectionally towards the central collection tank 132, the UV disinfection lamp 16 provided in the water passage 133 can further and more thoroughly disinfect the circulating working water.

[0070] Furthermore, the water passage 133 is equipped with a water-blocking bracket 14; the water-blocking bracket 14 is equipped with a baffle wall 141, which extends toward the UV disinfection lamp 16. The baffle plate of the water-blocking bracket 14 makes the water passage 133 form a "U"-shaped channel. The UV disinfection lamp 16 or other disinfection structures are arranged at the corner of this channel, which can make the circulating working water more fully and effectively disinfected.

[0071] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications and substitutions are all included within the scope defined by the claims of this application.
