Description

Technical Field

[0001] This invention relates to the field of humidifier technology, and in particular to a clean and wastewater separation type mist-free humidifier. Background Technology

[0002] The principle of a mist-free humidifier is to humidify the air by blowing moisture from a wet curtain into the external environment. This type of humidifier uses a water pump to draw water from the bottom tank to the top of the wet curtain for humidification. When the wet curtain or filter is saturated, excess water flows back to the bottom tank and is then circulated back to the wet curtain. However, outside air generally carries dust and bacteria, and this humidification method can easily cause dirt to accumulate in the bottom tank, resulting in unsanitary air produced by the mist-free humidifier. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a clean and wastewater separation type mist-free humidifier.

[0004] One embodiment of the present invention adopts the following technical solution to solve its technical problem: a clean water and wastewater separation type mist-free humidifier, comprising: a base, a first water tank, a second water tank, a control center, a wet curtain, and a fan assembly, a first water pump assembly, a second water pump assembly, and a first water level sensing assembly electrically connected to the control center;

[0005] The base is provided with a water curtain chamber and a blower chamber. The wet curtain is installed in the water curtain chamber, and the fan assembly is installed in the blower chamber. The first water tank can supply water to the wet curtain through the first water pump assembly. The second water tank can collect the water flowing out of the wet curtain. The second water tank can supply water to the wet curtain through the second water pump assembly.

[0006] The first water level sensing component can detect the water level of the second water tank and send the water level signal back to the control center; the control center can control the working status of the first water pump component according to the water level signal.

[0007] Optionally, a water curtain support is installed inside the water curtain chamber, and the wet curtain is installed on the water curtain support; a water curtain top cover is installed above the water curtain support to cover the wet curtain; the first water tank or the second water tank can supply water to the water curtain top cover, and the water curtain top cover can send water into the wet curtain.

[0008] Optionally, the water curtain top cover includes a bowl-shaped water curtain cover plate and a spray channel; the water curtain cover plate can collect water from the water curtain top cover and guide it to the spray channel; the spray channel is correspondingly arranged above the wet curtain.

[0009] Optionally, the spray channel is provided with a plurality of spray holes evenly distributed.

[0010] Optionally, a duct base plate is provided above the water curtain top cover, which can cover the water curtain cover plate and the spray channel.

[0011] Optionally, the water curtain support is equipped with an air filter element, which is arranged around the outside of the wet curtain; the base is also equipped with a mesh cover; the mesh cover has a plurality of filter holes, which are spaced apart and fitted around the outside of the water curtain support.

[0012] Optionally, the clean and wastewater separation type mist-free humidifier further includes a top cover assembly, which is detachably installed on the base and forms a guide air duct; the first water tank is detachably installed on the base and located inside the top cover assembly.

[0013] Optionally, the top cover assembly includes a top cover and a middle sleeve. The middle sleeve is spaced out on the outside of the first water tank and forms the airflow duct with the outer wall of the first water tank. The top cover is located on top of the middle sleeve and can cover the first water tank. The top cover is provided with a water injection channel, through which water can be injected into the first water tank.

[0014] Optionally, the first water tank is provided with a drain outlet, and a drain assembly is connected between the drain outlet and the first water pump assembly. The drain assembly can control the opening or closing of the drain outlet.

[0015] Optionally, the base has a middle mounting seat on top; the top cover assembly is mounted on the middle mounting seat; the middle of the middle mounting seat has a recessed structure for placing the first water tank; a receiving chamber is provided below the recessed structure, and the receiving chamber can be used to install the fan assembly and the first water pump assembly.

[0016] The beneficial effects of this invention are as follows: The fan assembly creates a negative pressure airflow, causing outside air to pass through the wet curtain in the water curtain chamber, forming fog-free air rich in water vapor and high humidity, which is then drawn into the blower chamber and subsequently sent out to the outside environment. The fog-free humidifier provided by this technical solution has two independent water tanks. The first water tank serves as the main water tank for storing water, and the second water tank serves as the working circulating water tank for collecting water flowing out of the wet curtain. In operation, the control center controls the first water pump assembly to supply water from the first water tank to the wet curtain. Once the wet curtain is saturated, the overflowing water flows out and is collected by the second water tank. The first water level sensor can detect the water level in the second water tank and send a water level signal back to the control center. Based on the water level signal, the control center can control the working state of the first water pump assembly to close or open the water supply channel from the first water tank to the wet curtain. When the water level in the second water tank reaches a high level, the control center shuts off the first water pump assembly and closes the water supply channel of the first water tank. The second water pump assembly can then pump water from the second water tank and send it to the wet curtain, achieving a circulating spraying effect only through the water in the second water tank. When the water in the second water tank is insufficient, the first water pump assembly is turned on again to replenish the water.

[0017] This invention utilizes two separate water tanks. The second water tank serves as the working circulation tank, which may accumulate some dirt during operation. However, the second water tank has a small water capacity, making it difficult for the accumulated dirt to spread further. The first water tank, serving as the main water storage chamber, is independently set up from the second water tank. The clean water inside is not diffused by the dirt in the second water tank. Water is only supplied to the wet curtain when the humidifier is working and the water level in the second water tank is insufficient. This ensures that the clean water is largely carried away by the negative pressure airflow during the working circulation process, preventing the dirt from spreading due to prolonged circulation in the second water tank. This results in cleaner and more hygienic air during the operation of the mist-free humidifier.

[0034] Example

[0035] Reference Figures 1 to 8 The present invention proposes a clean and wastewater separation type mist-free humidifier, comprising: a base 10, a first water tank 20, a second water tank 30, a control center 40, a wet curtain 50, and a fan assembly 60, a first water pump assembly 70, a second water pump assembly 71, and a first water level sensing assembly 80 electrically connected to the control center 40.

[0036] The base 10 is provided with a water curtain chamber 11 and a blower chamber 12. The wet curtain 50 is installed in the water curtain chamber 11, and the fan assembly 60 is installed in the blower chamber 12. The first water tank 20 can supply water to the wet curtain 50 through the first water pump assembly 70. The second water tank 30 can collect the water flowing out of the wet curtain 50. The second water tank 30 can supply water to the wet curtain 50 through the second water pump assembly 71.

[0037] The first water level sensing component 80 can detect the water level of the second water tank 30 and send the water level signal back to the control center 40; the control center 40 can control the working status of the first water pump component 70 according to the water level signal.

[0038] In this invention, the fan assembly 60 creates a negative pressure airflow, causing outside air to pass through the wet curtain 50 in the water curtain chamber 11, forming fog-free air rich in water vapor and high humidity. This air is then drawn into the blower chamber 12 and subsequently discharged into the external environment. The fog-free humidifier provided by this technical solution has two independent water tanks. The first water tank 20 serves as the main water tank for storing water, while the second water tank 30 serves as the working circulating water tank for collecting water flowing out of the wet curtain 50. In operation, the control center 40 controls the first water pump assembly 70 to supply water from the first water tank 20 to the wet curtain 50. After the wet curtain 50 is saturated with water, the overflowing water flows out and is collected by the second water tank 30. The first water level sensor assembly 80 can detect the water level in the second water tank 30 and send a water level signal back to the control center 40. Based on the water level signal, the control center 40 can control the working state of the first water pump assembly 70 to close or open the water supply channel from the first water tank 20 to the wet curtain 50. When the water level in the second water tank 30 reaches a high level, the control center 40 shuts off the first water pump assembly 70 and closes the water supply channel of the first water tank 20. The second water pump assembly 71 can pump water from the second water tank 30 and send it to the wet curtain 50, achieving a circulating spraying effect only through the water in the second water tank 30. When the water in the second water tank 30 is insufficient, the first water pump assembly 70 is turned on again to replenish the water.

[0039] This invention utilizes two separate water tanks. The second water tank 30 serves as the working circulation tank, which accumulates some dirt during operation. However, the second water tank 30 has a small water capacity, making it difficult for the accumulated dirt to spread further. The first water tank 20, serving as the main water storage chamber, is independently set up from the second water tank 30. The clean water inside is not diffused by the dirt in the second water tank 30. Water is only supplied to the wet curtain 50 when the humidifier is working and the water level in the second water tank 30 is insufficient. This ensures that the clean water is largely carried away by the negative pressure airflow during the working circulation process, preventing the dirt from spreading due to prolonged circulation in the second water tank 30. This results in cleaner and more hygienic air during the operation of the mist-free humidifier.

[0040] In this embodiment, a water curtain support 51 is installed inside the water curtain chamber 11, and the wet curtain 50 is installed on the water curtain support 51. A water curtain top cover 52 is installed above the water curtain support 51 to cover the wet curtain 50. The first water tank 20 or the second water tank 30 can supply water to the water curtain top cover 52, which can send water into the wet curtain 50. The water curtain support 51 is provided with a water curtain top cover 52 for mounting on the frame structure. By covering the water curtain support 51, the installation of the wet curtain 50 and air filter element 54 can be completed. The water curtain top cover 52 is located above the wet curtain 50, providing a large water collection chamber space to initially collect the water supplied by the first water tank 20 and the second water tank 30, and then spray it onto the wet curtain 50 from above, effectively spraying water into the wet curtain 50, ensuring the water absorption saturation of the wet curtain 50, and ensuring the humidity of the fog-free air.

[0041] Specifically, the water curtain top cover 52 includes a bowl-shaped water curtain cover plate 521 and a spray channel 522; the water curtain cover plate 521 can collect water from the water curtain top cover 52 and guide it to the spray channel 522; the spray channel 522 is correspondingly arranged above the wet curtain 50. The bowl-shaped water channel cover plate can both cover the water curtain support 51 and effectively collect water from the water channel top cover and guide it into the spray channel 522 for targeted spraying onto the wet curtain 50.

[0042] Furthermore, the spray channel 522 is evenly provided with a number of spray holes 523. The spray channel 522 is set above the cross-section of the wet curtain 50, and the evenly distributed spray holes 523 can evenly spray water onto the wet curtain 50, so that the airflow passing through the wet curtain 50 can achieve the effect of evenly carrying water vapor.

[0043] In some embodiments, a duct base plate 53 is provided above the water curtain top cover 52, which can cover the water curtain cover plate 521 and the spray channel 522. The duct base plate 53 separates the water curtain top cover 52 from the blower chamber 12. The mist-free air flowing in the blower chamber 12 is less likely to interfere with the water collected above the water curtain top cover 52, preventing water on the water curtain top cover 52 from splashing or overflowing.

[0044] In some embodiments, the water curtain support 51 is equipped with an air filter 54, which is arranged around the outside of the wet curtain 50; the base 10 is also equipped with a mesh cover 55; the mesh cover 55 has a plurality of filter holes, which are spaced apart and fitted around the outside of the water curtain support 51. Through the air filter 54 and the mesh cover 55, dirt and dust in the filtered air can be effectively blocked, reducing the amount of dirt carried by the airflow through the wet curtain 50, making the fog-free air cleaner and more hygienic. Preferably, the air filter 54 is a HEAP air filter 54.

[0045] In some embodiments, the clean and wastewater separation type mist-free humidifier further includes a top cover assembly 90, which is detachably mounted on the base 10 and forms a guide air duct 91; a first water tank 20 is detachably mounted on the base 10 and located inside the top cover assembly 90. Water can be added to the first water tank 20 by lifting and removing the top cover assembly 90; in addition, since the first water tank 20 is detachably mounted on the base 10, after removing the top cover assembly 90, the first water tank 20 can be directly lifted and removed for adding water or cleaning in places such as washbasins, making it very convenient for users to add water and clean.

[0046] Specifically, the blower chamber 12 is located above the water curtain chamber 11; and the first water tank 20 is located above the blower chamber 12 to facilitate disassembly and removal.

[0047] In this embodiment, the top cover assembly 90 includes a top cover 92 and a middle sleeve 93. The middle sleeve 93 is spaced out on the outside of the first water tank 20 and forms a guide air duct 91 with the outer wall of the first water tank 20. The top cover 92 is located on top of the middle sleeve 93 and can cover the first water tank 20. The overall shell of the humidifier has a cylindrical structure with an open top. The middle sleeve 93 is fitted on the outside of the water tank, which can protect the water tank and also form a mist guiding channel for high humidity air to pass through. The structure is compact and the air circulation is continuous. It can also effectively protect the water tank and prevent dirt in the air from entering the water tank.

[0048] Furthermore, the top cover 92 is provided with a water inlet channel 94, through which water can be injected into the first water tank 20. Water can be added directly from above into the water storage chamber of the water tank through the water inlet channel 94 without disassembling the top cover assembly 90 or removing the water tank, allowing users to choose the water filling method more flexibly according to their usage conditions.

[0049] In some embodiments, the top cover 92 includes an annular air outlet grille 921 and a top cover 922; the top cover 922 is located above the first water tank 20; the air outlet grille 921 surrounds the outer edge of the top cover 922 and is provided with water injection channels 94 at intervals from the top cover 922. The air outlet grille 921 is connected to the air guide duct 91 and has a plurality of air outlets, while the top cover 922 is located above the first water tank 20 and can cover the first water tank 20 to prevent dirt from directly entering the first water tank 20; the air outlet grille 921, through the plurality of channels formed at intervals from the top cover 922, can serve as water injection channels 94 to directly inject water into the water storage chamber.

[0050] Furthermore, the top cover 922 has an arc-shaped top surface. When water is injected into the top cover 922, it flows to the outer edge of the arc-shaped top surface and is then sent into the first water tank 20 through the water injection channel 94, making water filling smoother and more convenient.

[0051] In this embodiment, the first water tank 20 is provided with a drain outlet 21, and a drain assembly 72 is connected between the drain outlet 21 and the first water pump assembly 70. The drain assembly 72 can control the opening or closing of the drain outlet 21. The drain assembly 72 includes a stop valve that can block the drain outlet 21. In the non-working state, the drain outlet 21 is closed by the stop valve. When the first water tank 20 needs to supply water, the drain assembly 72, in conjunction with the first water pump assembly 70, pushes the stop plug or deforms the stop plug to open the drain outlet 21, thereby supplying water to the water curtain top cover 52.

[0052] Specifically, the structures such as the water-stop plug and the drainage component 72 are direct applications of existing technologies and will not be described in detail here.

[0053] In this embodiment, the base 10 is provided with a middle layer mounting seat 13 at the top; the top cover assembly 90 is mounted on the middle layer mounting seat 13; the middle of the middle layer mounting seat 13 is provided with a recessed structure 131 for placing the first water tank 20; the outer edge of the middle layer mounting seat 13 is provided with a baffle wall, which facilitates the detachable installation of the top cover assembly 90 on the baffle wall; and the recessed structure 131 facilitates the installation and removal of the first water tank 20.

[0054] Specifically, a receiving chamber 14 is provided below the recessed structure 131, which can be used to install the fan assembly 60 and the first water pump assembly 70.

[0055] To improve the water purification and sterilization capabilities and make the atomized air of the mistless humidifier cleaner, the containment cavity is also equipped with a heating element 74, a UV lamp assembly 75, and other purification and sterilization software. The water output from the first water tank 20 passes through the heating element 74 and the UV lamp assembly 75 via a water pipe 73. After sterilization and disinfection, it is sent to the top cover 52 of the water curtain and enters the operation of the circulating spraying wet curtain 50.

[0056] To prevent water from overflowing during the process of adding water to the first water tank 20, a second water level sensor 81 is installed on the top cover assembly 90. This sensor can detect the water level in the first water tank 20 and send the water level signal back to the control center 40 to issue an alarm in a timely manner.

[0057] To make the appearance of the mist-free humidifier more diverse, components such as light strips, duct light rings and display panels are arranged on the top cover assembly 90.

[0058] 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. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
