The names of messages or information interacted between the various devices in the embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of such messages or information.

The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

First, referring to fig. 1, fig. 1 is a schematic structural view of some embodiments of a humidifier according to the present disclosure. As shown in fig. 1, the humidifier may include a housing 1, a blower 2, a segmented humidifying mesh assembly 3, and a water replenishment assembly 4. The fan 2 is provided in the housing 1. A segmented humidifying mesh assembly 3 is provided below the blower 2. A plurality of air inlets, an air inlet grille, or the like are provided in the casing 1 in the section where the segmented humidifying net assembly 3 is located. The segmented humidifying mesh assembly 3 may include a first humidifying mesh assembly 31 and a second humidifying mesh assembly 32 arranged in a longitudinal arrangement. The water supplementing assembly 4 is used for supplementing water for the segmented humidifying net assembly 3. The refill end of refill assembly 4 (the left end of refill tube 42 in the figure) may be in communication with first humidification screen assembly 31 such that refill water wets first humidification screen assembly 31. When the first humidification screen assembly 31 is immersed, water overflows to the second humidification screen assembly 32, and the segmented humidification screen assembly 3 is immersed. Under the operating condition, the fan 2 attracts external dry air to enter through the air inlet, and then passes through the immersed sectional type humidifying net assembly 3, finally, moist air is formed and discharged to the outside of the humidifier, and the humidifying process is completed.

With continued reference to fig. 1, the first humidification mesh set 31 may optionally include a first humidification mesh 311 disposed in a ring shape and a first water storage tank 312 disposed at a bottom end of the first humidification mesh 311 for storing water. Specifically, the first humidification mesh 311 may be placed in the first water storage tank 312. The water replenishing end of the water replenishing assembly 4 may be connected to the top end of the first humidification screen 311, so that the first humidification screen 311 may be showered from top to bottom. Excess water is collected in the first water storage tank 312, and the water may spread upward from the bottom of the first humidification screen 311 by capillary phenomenon, thereby wetting the first humidification screen 311.

In addition, the water replenishing end may be connected to the first water storage tank 312. The first water storage tank 312 is further soaked in the first humidifying net 311 by capillary phenomenon. Because the working section of the first humidification mesh 311 is shorter than that of the humidification mesh integrally arranged with the related humidifier, the capillary phenomenon effect of the first humidification mesh 311 is better, so that the first humidification mesh 311 is completely soaked, and the humidification amount and the humidification effect of the humidifier are improved.

The second humidification screen assembly 32 may include a second humidification screen 321 disposed in a ring shape and a second water storage tank 322 for storing water. Similarly, the second water storage tank 322 may be placed in the second water storage tank 322. When the first humidification mesh 311 is soaked, the excessive water overflows from the first water storage tank 312 to the second humidification mesh 321, so that the second humidification mesh 321 is showered from top to bottom. Thereafter, the surplus water is collected in the second water storage tank 322, and the water is spread from bottom to top through capillary phenomenon from the bottom of the second humidification mesh 321, so that the second humidification mesh 321 is completely immersed. Also, since the working section of the second humidification mesh 321 is shorter than the integrally provided humidification mesh of the related humidifier, the capillary phenomenon of the second humidification mesh 321 is more effective.

Further, in order to make the water in the first water storage tank 312 smoothly enter the second humidification screen assembly 32, so as to avoid splashing water around and hanging on the casing, thereby wasting water, an overflow assembly may be disposed between the first water storage tank 312 and the second humidification screen 321. Next, description will be given with reference to fig. 2, 3 and 4. Fig. 2 is a cross-sectional view of some embodiments of overflows according to the present disclosure. Fig. 3 is a cross-sectional view of other embodiments of overflows according to the present disclosure. Fig. 4 is a perspective view of some embodiments of overflows according to the present disclosure. As shown in fig. 2, 3 and 4, the overflow assembly may include an annular water distribution channel 33 and a plurality of overflows. The annular water diversion trench 33 is provided to the bottom of the first water storage trench 312, and a side wall of the annular water diversion trench 33 is engageable with the bottom of the first water storage trench 312. The annular water diversion channel 33 is positioned at the upper end of the second humidifying mesh 321. The bottom of the annular water diversion trench 33 may be adapted to the cross-sectional shape of the second humidifying mesh 321. The overflow portions are provided in the first water storage tank 312 such that the first water storage tank 312 communicates with the annular water diversion tank 33. Specifically, the overflow portion may include a main body 35 and an overflow passage 38 penetrating the main body 35. The main body 35 may be hollow to form the overflow passage. An inlet end 36 of the overflow channel 38 extends through the upper end of the body 35. The outlet end 37 of the overflow channel 38 extends through the bottom of the main body 35 and the floor of the first reservoir 312. In this way, when the liquid level in the first water storage tank 312 is higher than the inlet end 36 of the overflow channel 38, water flows into the annular water diversion channel 33 through the overflow channel 38. It should be noted that the height of the inlet end 36 of the overflow channel 38 may be adjusted according to practical situations. Further, a plurality of infiltration holes 34 may be formed in the bottom plate of the annular water diversion trench 33. The infiltration holes 34 allow the annular watershed 33 to communicate with the second humidification mesh 321. In this way, the water in the annular water diversion trench 33 can infiltrate the second humidifying net 321 through the infiltration holes 34. It should be noted that the shape of the main body 35 of the overflow portion is not limited to the above, and may be adjusted by those skilled in the art according to practical situations.

Further, the side walls of the first water storage tank 312 and the second water storage tank 322 may be extended to be connected. The water in the annular water diversion groove 33 can directly enter the second water storage groove 322 without overflowing to the shell 1.

Next, please refer to fig. 5 and refer back to fig. 1. Fig. 5 is a schematic structural view of further embodiments of a humidifier according to the present disclosure. In order to determine whether water replenishment is required through the water amount information of the first water storage tank 312 and the second water storage tank 322, a level sensor may be provided in the first water storage tank 312 and the second water storage tank 322.

In addition, it is also possible to determine whether to replenish the water by merely detecting the level of the second water storage tank 322. Specifically, the refill assembly 4 may include a refill tube 42 and an electrically connected controller and first electrically controlled valve 44. The water outlet end (left end in the drawing) of the water replenishment pipe 42 is the water replenishment end. A first electrically controlled valve 44 may be provided on the water replenishment pipe 42, and a first level sensor (not shown) electrically connected to the controller may be provided on the second water storage tank 322. Here, the amount of water in the second water storage tank 322 may be reacted by the first level sensor. In the operating state, when the liquid level on the second water storage tank 322 reaches the peak liquid level, the first liquid level sensor sends a signal to the controller, and the controller controls the first electric control valve 44 to be closed, so that the water supplementing pipe 42 can be closed. At this time, the second water storage tank 322 and the first water storage tank 312 are full.

When the liquid level of the second water storage tank 322 is lower than the valley liquid level, the first liquid level sensor sends a signal to the controller, and the controller can open the water supplementing pipe 42 to supplement water. Further, to avoid the situation that the water in the first water storage tank 312 is already running when the liquid level in the second water storage tank 322 is lower than the valley liquid level, the person skilled in the art can adjust the valley liquid level to ensure that the water is always present in the first water storage tank 312. Alternatively, the first water storage tank 312 and the second water storage tank 322 may be structurally improved, so that water is always stored in the first water storage tank 312, and further, the situation that humidification is not possible due to untimely water supplementing is avoided.

As an example, since the rates of evaporation and consumption of the water amount during the humidification process are uniform in the first and second humidification nets 311 and 321, the volume of the first water storage tank 312 may be set to be greater than the volume of the second water storage tank 322. For example, in the case where the cross-sectional areas of the first water storage tank 312 and the second water storage tank 322 are identical, the water holding height of the second water storage tank 322 is set to be lower than the water holding height of the first water storage tank 312. In this way, the liquid level of the second water storage tank 322 is always lower than that of the first water storage tank 312 during the soaking and humidifying processes. Therefore, the first water storage tank 312 can always be guaranteed to have water therein.

Further, the first water storage tank 312 and the second water storage tank 322 may be set to have the same water holding height, and the cross-sectional area of the second water storage tank 322 is smaller than that of the first water storage tank 312, so that the range of variation of the liquid level of the second water storage tank 322 is larger, and thus, the first liquid level sensor is more sensitive when detecting the variation of the liquid level.

In general, by providing the first level sensor only in the second water storage tank 322, it is possible to sensitively determine whether the first water storage tank 312 and the second water storage tank 322 need to be replenished with water. Specifically, when the liquid level of the second water storage tank 322 is at the peak level, the water in the second water storage tank 322 overflows through the first water storage tank 312, so that the water in the first water storage tank 312 and the second water storage tank 322 are full, and the water supplementing pipe 42 can be closed. As the humidification process proceeds, the water in the first and second water storage tanks 312 and 322 gradually decreases. Since the level of the second water storage tank 322 is lower than the valley level, water is stored in the first water storage tank 312. Therefore, in the process of opening the water supplementing pipe 42 to supplement water, the water in the first water storage tank 312 can be used in a transitional mode, the phenomenon that the water is not timely supplemented to cause the water cannot be humidified is avoided, and the reliability of the humidifier is improved.

It should be noted that the peak level and the valley level may be determined by the height and trial and error of the first water storage tank 312 and the second water storage tank 322.

Alternatively, the first liquid level sensor may include a first floating ball and a first sensing sensor. The first floating ball is placed in the second water storage tank 322 and can rise and fall along with the liquid level. The first inductive sensor may be provided to the bottom or side wall of the second reservoir. Under the working condition, the first induction sensor can determine the liquid level by sensing the position of the first floating ball.

In some alternative implementations of some embodiments, in order to avoid that the first electronically controlled valve 44 cannot be controlled to close in time when the first liquid level sensor fails, so that water in the second water storage tank 322 overflows, a containing cavity 5 may be provided between the second water storage tank 322 and the bottom of the housing 1. The receiving chamber 5 is used for storing water overflowed from the second water storage tank 322. Wherein, a second liquid level sensor electrically connected with the controller can be arranged in the accommodating cavity 5. In the working state, the controller controls the first electric control valve 44 to be closed in response to the second liquid level sensor detecting that the liquid level in the accommodating cavity 5 exceeds the preset liquid level. Further, an alarm message may be sent to the control end of the sensor, thereby alerting the user. The mode of warning the user can be a flashing lamp, buzzing vibration, a mode of displaying warning graphics and the like. Therefore, when the first liquid level sensor fails and water supplementing cannot be stopped in time, the second water storage tank 322 overflows more water, short circuit risks and the like can be avoided. Thereby improving the safety of the humidifier. It should be noted that the preset liquid level may be determined through continuous experiments and attempts.

The second liquid level sensor may include a second float ball and a second sensing sensor.

As an example, the first and second floating balls may be metal-wrapped floating balls, and the first and second sensing sensors may be proximity switch sensors. As another example, the first and second floating balls may be floating balls wrapped with a magnet, and the first and second sensing sensors may be hall sensors. Those skilled in the art can choose according to the actual circumstances.

Still further, in order to avoid the occurrence of the failure of the first electrically controlled valve 44 and the inability to stop the water supply in time, a second electrically controlled valve 45 may be provided on the water supply pipe 42. The second electrically controlled valve 45 is connected in series with the first electrically controlled valve 44. The second electrically controlled valve 45 may be electrically connected to the controller, and the second electrically controlled valve 45 may be set to a normally open state. Specifically, when the first liquid level sensor detects that the liquid level in the second water storage tank 322 exceeds the preset liquid level, the second electric control valve 45 is directly closed or the first electric control valve 44 and the second electric control valve 45 are simultaneously closed, so that water supplementing is stopped.

Further, when the first electric control valve 44 and the first liquid level sensor are both failed, the controller may control the second electric control valve 45 to close by receiving the signal sent by the second liquid level sensor after water enters the accommodating cavity, so as to stop water replenishment.

The first electrically controlled valve 44 and the second electrically controlled valve 45 may be solenoid valves, electrically operated valves, pneumatic valves, or the like. Those skilled in the art can adjust the device according to the actual situation.

Finally, referring back to fig. 1, the refill assembly 4 may further include a water tank 41. The water inlet end (right end in the drawing) of the water replenishing pipe 42 may be connected to the water tank 41, and water is supplied to the first water storage tank through the water replenishing pipe 42 by a water pump.

Alternatively, the humidifier may eliminate the water pump, reducing cost and power consumption. Specifically, the water tank 41 may be provided to one side of the above-described segmented humidifying net assembly 3. The bottom of the water tank 41 is provided with a water outlet connected with the water inlet end of the water supplementing pipe 42. It should be emphasized that the height of the water outlet is higher than the water outlet end of the water supplementing pipe 42. So that both ends of the water supply pipe 42 are connected to the water tank 41 and the first water storage tank 312 with a drop. So that the water flow can flow to the first water storage tank under the action of gravity.

The upper end of the water tank may be provided with a diverter plate 44 having an arc-shaped protrusion in cross section, so that water flows into the water tank 41 along the surface of the diverter plate 44 during the water feeding process.

Further, the water tank 41 may be provided to be detachably mounted in the housing 1. A valve 43 may be provided at the outlet of the tank. When the water tank 41 is installed, the valve 43 is opened and water enters the water replenishment pipe 42. When the water tank 41 is detached, the valve is closed, avoiding leakage. The valve 43 may be a mechanical valve, for example, a sleeve end and a plug end of a self-locking quick-release connector are respectively disposed on the water tank 41 and a fixing plate for placing the water tank 41. The valve 43 may be an electrically operated valve, such as an electromagnetic valve, an electrically operated valve, a pneumatic valve, or the like. Thereby facilitating the disassembly of the water tank. Those skilled in the art can adjust the device according to the actual situation.

The present disclosure also provides a water replenishment control method for a humidifier, which can be used for the humidifier in the above embodiments. As shown in fig. 6, a flow 400 of some embodiments of a method of controlling water replenishment for a humidifier provided by the present disclosure is shown. The method may comprise the steps of:

and 601, receiving liquid level information sent by a first liquid level sensor arranged in a second water storage tank.

In some embodiments, the method is generally performed by the controller in the above embodiments. The controller may be a control system of the humidifier, a server, or other electronic device. Such as a control chip or the like. The first liquid level sensor is used for detecting the liquid level of the second water storage tank, the first liquid level sensor can be a liquid level meter with a data transmission function, and the collected liquid level information can be sent to a controller electrically connected with the first liquid level sensor, so that the controller can receive the liquid level information. The liquid level information can be a liquid level height value or a liquid level range value, and can be adjusted according to actual conditions by a person skilled in the art.

In step 602, a first electrically controlled valve disposed on the water replenishment pipe is controlled to open in response to the liquid level characterized by the liquid level information being below a valley liquid level.

In some embodiments, the controller may store a preset level value that characterizes the valley level. The controller compares the received liquid level value represented by the liquid level information with the liquid level value represented by the valley liquid level. When the liquid level value of the liquid level information representation collected by the first liquid level sensor is smaller than the liquid level value of the valley liquid level representation, the second water storage tank is represented to be required to be supplemented with water. The controller controls the opening of a first electric control valve arranged on the water supplementing pipe so as to supplement water.

Further, the first water storage tank and the second water storage tank are arranged so that water is stored in the first water storage tank when the liquid level of the second water storage tank is lower than the valley liquid level. As in the previous embodiments, the valley level may be adjusted by those skilled in the art to ensure that water is always present in the first reservoir. Or, also can improve first aqua storage tank and second aqua storage tank structurally for the water is stored all the time in the aforesaid first aqua storage tank, and then avoids moisturizing untimely and leads to unable humidification's condition to take place. The implementation manner of the first water storage tank and the second water storage tank is described in the above embodiments, and details are not repeated here.
