Referring to fig. 1 and 2, an embodiment of the present invention is an evaporation water tank lower circulation pipeline structure of a purification humidifier, which is suitable for being applied to a longitudinally-arranged evaporation humidifier, such as the structure disclosed in chinese patent publication No. CN111912069A mentioned in the background of the invention, in this embodiment, a cleaning-free circulation water filtering structure includes an evaporation water tank 1, an evaporator 5 is disposed inside the evaporation water tank 1, a lower portion of the evaporator 5 is immersed in the evaporation water tank 1, the evaporation water tank 1 is disposed right below a water storage tank 3, and the evaporator 5 surrounds an outside of the water storage tank 3, wherein the water storage tank 3 is further communicated with the evaporation water tank 1 through a water outlet, so that water in the water storage tank 3 can flow into the evaporation water tank 1 and be absorbed by the evaporator 5 to evaporate under the action of an air flow, thereby completing humidification.

More importantly, in the structure of the embodiment, the water evaporator comprises the water evaporator tank 1, the water evaporator tank 1 is communicated with the water pump 2 through the first pipeline 10, the water pump 2 is also communicated with the water storage tank 3 through the second pipeline 11, and the first pipeline 11 and the second pipeline 12 form a circulating pipeline between the water storage tank 3 and the water evaporator tank 1; further, a filter module 4 of an arbitrary structure is attached to the second pipe, and then, as shown in fig. 2, the lower portion of the second pipe and the first pipe are annularly attached to the lower portion of the evaporation water tank 1, and based on this structure, the water pump 2 is fitted to the lower portion of the evaporation water tank 1. So that the water pump 2 can pump the water flowing into the evaporation water tank 1 from the water outlet of the water storage tank 1 into the water storage tank 3 through the filtering module 4, and the water is circularly filtered between the water storage tank 3 and the evaporation water tank 1; in the process, the water pumping amount of the water pump 2 is basically equal to the water outlet amount of the water outlet of the water storage tank 3, so that the operation of the water pump 2 does not influence the liquid level in the evaporation water tank 1, but the water in the evaporation water tank 1 is all running water due to the circulating water system formed by the operation of the water pump 2, and the deposition of impurities in the evaporation water tank 1 can be reduced or eliminated as far as possible because the water stays in the evaporation water tank 1 for a long time. The impurities in the water are all concentrated in the filter module 4 through the circulating filter system, the filter module 4 is arranged on the upper part of the water storage tank 3, so that the filter module is convenient to disassemble, assemble and clean, and the filter module 4 also has a large bearing area, so that the filter module is not required to be disassembled and cleaned frequently.

On the other hand, in order to keep the liquid level in the evaporation water tank 1 constant and avoid the influence of too little water on the humidification effect and the water leakage of the humidifier caused by overflow due to too much water, a water level sensor can be installed in the evaporation water tank 1, and a spring valve is preferably installed at the water outlet of the water storage tank 3, wherein the spring valve is in a normally closed state under the action of a spring, and correspondingly, a corresponding ejector rod device is also needed to be installed in the evaporation water tank 1, and comprises an ejector rod body and a driving motor, the driving motor drives the ejector rod body to move up and down through the rotation of a gear rack, when the ejector rod body moves up, the spring valve can be ejected, at the moment, the water outlet of the water storage tank 3 is opened, water can flow into the evaporation water tank, and otherwise, the water outlet is closed. And then can gather the liquid level value in the evaporation water tank 1 by the level sensor, open and stop according to the aforesaid driving motor of level value control by the control module to the opening and closing of aforesaid spring valve is controlled, namely the switching of the sewer between control storage water tank 3 and evaporation water tank 1. Through the mode, a float valve in the evaporation water tank 1 is omitted, so that the inner cavity structure of the evaporation water tank 1 becomes simpler, the impurity deposition is further reduced, and the cleaning is convenient.

On the other hand, in the embodiment, the inventor also improves the problem of another pain point of the humidifier, and since the humidifier adopts an external water source to continuously supply water to realize the function of no water adding, the water leakage is caused to avoid the overflow of the overhigh water level in the water storage tank 3, and then the floor is wetted. For the above problems, as shown in fig. 2, an ultra-high level warning sensor may be further installed inside the water storage tank 3, the ultra-high level warning sensor 14 may employ probes having positive and negative electrodes, the probes are triggered when the water level in the water storage tank 3 reaches a calibrated ultra-high water level, and then transmit a sensing signal to the control module, the control module controls the valve body of the external water source to close, so that the external water no longer flows into the evaporation water tank 1, and further the excess water is no longer pumped back into the water storage tank 3 by the water pump 2, thereby avoiding overflow caused by the continuous rise of the water level in the water storage tank 3, after the water level in the water storage tank 3 drops during the use of the humidifier, the valve body of the external water source may be opened again, and the process is repeated.

In this embodiment, be annular through the circulating line who constitutes first pipeline and second pipeline and install in evaporation water tank 1 lower part to add water pump 2 on the circulating line, return the water in evaporation water tank 1 through water pump 2 and pump into storage water tank 3, participate in to carry out circulating filtration to water by filter module 4 at this in-process, and then avoid evaporation water tank 1 and storage water tank 3 in the impurity deposit appear and lead to mildening and rot and produce the peculiar smell, effectively solved evaporation humidifier and need regularly abluent pain point problem in the use.

In another embodiment of the present invention, as shown in fig. 3, in order to improve the filtering efficiency and the receiving area and space, the inventor further improves the structure of the filtering module 4, specifically, the filtering module 4 is directly installed on the upper portion of the water storage tank 3 as described above for easy detachment; the filtering module 4 is designed into a split structure and comprises a box body 41, then a filtering net 42 is arranged in the box body 41, and the filtering density of the filtering net 42 can be designed into the density capable of filtering impurities in water; and the area of the filter screen 42 is adapted to the upper opening of the water storage tank 3, and the second pipe between the water storage tank 3 and the water pump 2 can be communicated with any position of the filter screen 42, i.e. the water pumped from the evaporation water tank 1 by the water storage tank 3 firstly flows into the filter screen 42, then flows into the interior of the water storage tank 3 through the filter screen 42.

As shown in fig. 2, it is preferable that a second pipe between the water pump 2 and the water storage tank 3 is embedded in the outer wall of the water storage tank 3, and the water pump 2 is embedded in the lower portion of the evaporation water tank 1, so that the water pump 2 and the circulation pipe do not substantially affect the inherent structure of the humidifier interior, in order to facilitate the installation of the circulation pipe. In the embodiment, as shown in fig. 4, the inventor further improves the cleanliness of the circulating water and prevents impurities in the filtering module 4 and the evaporation water tank 1 from mildewing due to bacteria, further installs a UV-C sterilization module 20 on the first pipeline between the water pump 2 and the evaporation water tank 1, and preferably installs the UV-C sterilization module 20 at the lower part of the evaporation water tank 1, the UV-C sterilization module 20 includes a housing 61, a section of transparent tube 62 is installed in the housing 61, and then installs a plurality of UV lamps on the inner wall of the housing 61, and the irradiation directions of the UV lamps correspond to the transparent tube 62, and both ends of the transparent tube 62 are respectively communicated with the pipeline. When water flows through the transparent tube body 62, bacteria in the water can be killed by the irradiation of the ultraviolet lamps, and the sterilization efficiency can be improved due to the simultaneous irradiation of the ultraviolet lamps; meanwhile, water in the evaporation water tank 1 is pumped into the water storage tank 3 through the filtering module 4 by the water pump 2 and then is discharged into the evaporation water tank 1 through the water outlet, so that the UV-C sterilization module 20 can circularly irradiate and sterilize the water, the bacterial content in the water is further reduced, and the foreign matters in the filtering module 4 and the evaporation water tank 1 are prevented from generating peculiar smell due to bacterial mildew. In other words, the UV-C sterilization module 20 with the above structure encapsulates the UV light inside the housing 61, and the closed pipe sterilization design prevents the UV light from leaking to hurt people and damage adjacent parts, and also effectively increases the UV irradiation intensity, thereby achieving true sterilization.

Further, referring to fig. 2, the inventor further improves the humidification amount of the humidifier, further installs a heating module 9 on the second pipeline between the water storage tank 3 and the water pump 2, the heating module 9 is designed to be a pipeline structure, the heating sheet contacts with water passing through the pipeline for heat conduction, and further heats the water, so that the heated water flows back to the water storage tank 3, and then flows into the evaporation water tank 1, because the water is more easily evaporated after being heated, the evaporation efficiency of the water attached to the evaporator 5 can be improved, for example, when the water temperature is heated to 37 ℃, the evaporation humidification efficiency can be increased by 1.5-2 times compared with the normal temperature, and further, under the same humidification amount, the rotation speed and noise of the fan can be reduced, so as to realize the mute humidification of <35dB, and improve the user experience. Meanwhile, a water temperature sensor is required to be installed in the evaporation water tank 1, heating is stopped when the water temperature reaches 37 ℃, so that scale is prevented from being generated in the evaporation water tank 1 due to overhigh temperature, and meanwhile, the water temperature in the evaporation water tank 1 can be controlled through the water temperature sensor.

Meanwhile, in order to avoid the heating module from being started when no water flows through, a water outlet sensor can be arranged on a water outlet pipeline of the water pump 2, the water outlet sensor collects water flowing out, then the control module controls the heating module 9 to be started, and therefore overheating risks can be avoided through the water outlet sensor, and the working state of the water pump 2 can be detected.

Referring to fig. 1 to 4, the circulation pipeline structure at the lower part of the evaporation water tank of the purification humidifier is applied to a vertical humidifier. When the longitudinally-arranged humidifier is used, sufficient water is added into the water storage tank 3, the water flows into the evaporation water tank 1 through the water outlet, when the liquid level in the evaporation water tank 1 reaches a preset maximum limit, the driving motor in the evaporation water tank 1 controls the ejector rob body to close the water outlet of the water storage tank 3, and the evaporator 5 starts to absorb the water in the evaporation water tank 1 and uniformly distributes the water on the upper part of the evaporation water tank; then the fan starts to rotate to generate negative pressure, then the airflow enters the airflow channel and contacts with the evaporator 5 to evaporate the moisture on the upper part of the airflow channel, and the moisture is discharged from an air outlet on the humidifier shell to humidify the indoor environment. In the foregoing process, the water in the evaporation water tank 1 can be continuously pumped out by the water pump 2, and is sterilized by the UV-C sterilization module 6 in sequence, and is filtered by the filtering module 4 and then flows back to the water storage tank 3. That is, as mentioned above, the water pumping amount of the water pump 2 is substantially equal to the water outlet amount of the water outlet of the water storage tank 3, so that the operation of the water pump 2 does not affect the liquid level in the evaporation water tank 1, but the water in the evaporation water tank 1 is all live water due to the circulating water system formed by the operation of the water pump 2, and the deposition of impurities in the evaporation water tank 1 can be reduced or eliminated as much as possible because the water stays in the evaporation water tank 1 for a long time. The impurities in the water are all concentrated in the filter module 4 through the circulating filter system, the filter module 4 is arranged on the upper part of the water storage tank 3, so that the filter module is convenient to disassemble, assemble and clean, and the filter module 4 also has a large bearing area and a large space, so that the filter module is not required to be disassembled and cleaned frequently.
