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

Referring first to fig. 1, fig. 1 is a schematic structural diagram 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 refill assembly 4. The above-described fan 2 is provided into the housing 1. A segmented humidifying mesh assembly 3 is provided below the fan 2. A plurality of air inlets are arranged on the housing 1 of the section where the sectional type 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 replenishing assembly 4 is used for replenishing water for the sectional type humidifying net assembly 3. The refill end (the left end of the refill tube 42 in the figure) of the refill assembly 4 may communicate with the first humidification screen assembly 31 such that the refill water wets the first humidification screen assembly 31. After the first humidification screen assembly 31 is completely soaked, the water overflows to the second humidification screen assembly 32, and the soaking of the segmented humidification screen assembly 3 is completed. In a working state, the fan 2 sucks external dry air to enter through the air inlet, and then the dry air passes through the soaked sectional type humidifying net component 3 to finally form humid air to be discharged to the outside of the humidifier, so that a humidifying process is completed.

With reference to fig. 1, the first humidification mesh group 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 and used 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 component 4 can be communicated to the top end of the first humidifying mesh 311, and then the first humidifying mesh 311 is poured from top to bottom. The excess water will be gathered in the first water storage tank 312, and then the water may also spread upwards from the bottom of the first humidification screen 311 by capillary phenomenon, so as to infiltrate the first humidification screen 311.

In addition, the water replenishing end can be connected with the first water storage tank 312. And the first water storage tank 312 soaks the first humidification net 311 by capillary phenomenon. Because the working section of the first humidification mesh 311 is shorter than the integrally arranged humidification mesh of the related humidifier, the capillary phenomenon effect of the first humidification mesh 311 is better, so that the first humidification mesh 311 is completely wetted, 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 annularly disposed and a second water storage tank 322 for storing water. Similarly, the second reservoir 322 may be placed in the second reservoir 322. After the first humidification mesh 311 is completely soaked, the excess water overflows from the first water storage tank 312 to the second humidification mesh 321, so that the second humidification mesh 321 is drenched from top to bottom. Thereafter, the excess water is gathered into the second water storage tank 322, and the water spreads from the bottom of the second humidification screen 321 to the top through capillary phenomenon, so that the second humidification screen 321 is completely soaked. Likewise, the working section of the second humidification mesh 321 is shorter than the integrally arranged humidification mesh of the related humidifier, so that the effect of the capillary phenomenon of the second humidification mesh 321 is better.

Further, in order to make the water in the first water storage tank 312 smoothly enter the second humidification net assembly 32, the situation that the water splashes around, the wall is hung on the shell, and then the water is wasted is avoided, an overflow assembly can be arranged between the first water storage tank 312 and the second humidification net 321. Next, description will be made with reference to fig. 2, 3, and 4. Fig. 2 is a cross-sectional view of some embodiments of an overflow according to the present disclosure. Fig. 3 is a cross-sectional view of other embodiments of an overflow according to the present disclosure. Fig. 4 is a perspective view of some embodiments of an overflow according to the present disclosure. As shown in fig. 2, 3 and 4, the overflow assembly may include an annular water diversion channel 33 and a plurality of overflow portions. The annular cutwater 33 is provided to the bottom of the first reservoir 312 and the sidewall of the annular cutwater 33 may be engaged with the bottom of the first reservoir 312. The annular diversion trench 33 is located at the upper end of the second humidification mesh 321. The floor of the annular cutwater 33 may be adapted to the cross-sectional shape of the second humidification screen 321. The plurality of overflows are provided to the first reservoir 312 such that the first reservoir 312 communicates with the annular diversion trench 33. Specifically, the overflow portion may include a main body 35 and an overflow passage 38 penetrating the main body 35. Wherein the main body 35 may be hollow to form the above-mentioned overflow channel. An inlet end 36 of an overflow channel 38 extends through the upper end of the body 35. The outlet end 37 of the overflow passage 38 penetrates the bottom of the main body 35 and the bottom plate of the first reservoir 312. Thus, when the liquid level in the first reservoir 312 is higher than the inlet end 36 of the overflow channel 38, the water will enter the annular diversion trench 33 through the overflow channel 38. It should be noted that the height of the inlet end 36 of the overflow channel 38 can be adjusted according to the actual situation. Furthermore, a plurality of infiltration holes 34 may be formed in the bottom plate of the annular water diversion trench 33. The wetting holes 34 allow the annular cutwater 33 to communicate with the second humidification screen 321. In this way, the water in the annular diversion trench 33 can infiltrate the second humidification mesh 321 through the infiltration holes 34. The shape of the main body 35 of the overflow part is not exclusive and can be adjusted by those skilled in the art according to the actual situation.

Further, the sidewalls of the first reservoir 312 and the second reservoir 322 may be extended to be connected. And thus the water in the annular diversion channel 33 can be directly introduced into the second reservoir 322 without overflowing the casing 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 and second water storage tanks 312 and 322, a level sensor may be provided in the first and second water storage tanks 312 and 322.

In addition, the water can be determined by detecting the liquid 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 figure) of the water replenishing pipe 42 is the water replenishing end. The water replenishing pipe 42 may be provided with a first electrically controlled valve 44, and the second water storage tank 322 may be provided with a first liquid level sensor (not shown) electrically connected to the controller. Here, the amount of water in the second water storage tank 322 may be reflected by the first level sensor. In an operating state, when the liquid level in 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 electronic control valve 44 to close, so that the water replenishing pipe 42 can be closed. At this time, the second reservoir 322 and the first reservoir 312 have sufficient water.

When the liquid level of the second water storage tank 322 is lower than the valley level, the first liquid level sensor sends a signal to the controller, and then the controller can open the water replenishing pipe 42 for water replenishing. Further, in order to avoid the situation that the water in the first water storage tank 312 is already running out when the liquid level of the second water storage tank 322 is lower than the valley level, the person skilled in the art can adjust the valley level to ensure that the water is always 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 the situation that humidification cannot be performed due to untimely water replenishment is avoided.

As an example, since the first and second humidification nets 311 and 321 evaporate the water at the same rate during humidification, the volume of the first water storage tank 312 may be set to be larger than the volume of the second water storage tank 322. For example, in the case where the first reservoir 312 and the second reservoir 322 have the same cross-sectional area, the water level of the second reservoir 322 is set to be lower than the water level of the first reservoir 312. Thus, the liquid level in the second water storage tank 322 is always lower than that in the first water storage tank 312 during the wetting and humidifying processes. Therefore, it can be ensured that water is always present in the first reservoir tank 312.

Further, the first water storage tank 312 and the second water storage tank 322 may be set to have the same water containing 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 liquid level of the second water storage tank 322 is changed in a wider range, and thus, the first liquid level sensor is more sensitive to detect the liquid level change.

In general, by providing the first level sensor only in the second reservoir 322, it is possible to sensitively determine whether the first reservoir 312 and the second reservoir 322 require water replenishment. Specifically, when the liquid level in the second reservoir 322 is at the peak level, the water in the second reservoir 322 is collected by the overflow of the first reservoir 312, so the water in the first reservoir 312 and the water in the second reservoir 322 are abundant, and the water replenishing pipe 42 can be closed. As the humidification operation is performed, the water in the first and second water storage tanks 312 and 322 is gradually decreased. Since the liquid level of the second reservoir 322 is lower than the valley level, the first reservoir 312 stores water. Therefore, in the process of starting the water replenishing pipe 42 to replenish water, the water in the first water storage tank 312 can be used in a transitional mode, the problem that humidification cannot be performed due to untimely water replenishing is avoided, and the reliability of the humidifier is improved.

It should be noted that the peak and valley levels may be determined by the height and trial and error of the first and second reservoirs 312 and 322.

Optionally, the first liquid level sensor may include a first floating ball and a first inductive sensor. The first floating ball is placed in the second water storage tank 322 and can ascend and descend along with the liquid level. The first inductive sensor may be provided to the bottom or the sidewall of the second water storage tank. Under the working state, the first induction sensor can determine the liquid level by sensing the position of the first floating ball.

In some optional implementations of some embodiments, in order to avoid the situation that the first electrically controlled valve 44 cannot be controlled to close in time when the first liquid level sensor fails, so as to cause the water in the second water storage tank 322 to overflow, an accommodating 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 overflowing 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 electrically controlled valve 44 to close in response to the second liquid level sensor detecting that the liquid level in the accommodating chamber 5 exceeds the preset liquid level. Further, alarm information can be sent to the control end of the sensor, and then a user is warned. The mode of warning the user can be a flashing light, a buzzing vibration, a display warning graph and the like. Therefore, the situation that when the first liquid level sensor breaks down and cannot timely stop water replenishing, more overflow water flows out of the second water storage tank 322, short-circuit risks are caused and the like can be avoided. Thereby improving the safety of the humidifier. It should be noted that the preset liquid level can be determined through continuous experiments and trials.

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

As an example, the first floating ball and the second floating ball may be floating balls wrapped with metal, and the first inductive sensor and the second inductive sensor may be proximity switch sensors. As another example, the first floating ball and the second floating ball may be floating balls wrapped with magnets, and the first inductive sensor and the second inductive sensor may be hall sensors. The selection can be made by those skilled in the art according to the actual situation.

Still further, in order to avoid the situation that the first electric control valve 44 fails and the water supply cannot be stopped in time, a second electric control 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 electronic control valve 45 is directly closed or the first electronic control valve 44 and the second electronic control valve 45 are simultaneously closed, and then water supplement is stopped.

Further, when the first electric control valve 44 and the first liquid level sensor both have faults, and water enters the accommodating cavity, the controller can control the second electric control valve 45 to close by receiving a signal sent by the second liquid level sensor, so as to stop water supplement.

The controller may be an electronic component having signal processing and control functions, such as a control chip.

The first and second electric control valves 44 and 45 may be solenoid valves, electric valves, pneumatic valves, or the like. The person skilled in the art can make adjustments 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 figure) of the water replenishing pipe 42 can be connected with the water tank 41, and water is conveyed to the first water storage tank through the water replenishing pipe 42 by a water pump. Alternatively, a third level sensor may be provided in the water tank 41 for monitoring the water level in the water tank 41.

Optionally, the humidifier may omit a water pump, reducing cost and power consumption. Specifically, the water tank 41 may be provided to one side of the above-described segmental humidification screen assembly 3. The bottom of the water tank 41 is provided with a water outlet connected with the water inlet end of the water replenishing pipe 42. It is emphasized that the height of the water outlet is higher than the water outlet end of the water replenishing pipe 42. So that both ends of the water replenishing pipe 42 are connected to the water tank 41 and the first water storage tank 312 with a fall. So that the water flows to the first water storage tank under the action of gravity.

The upper end of the water tank may be provided with a diversion plate 44 having an arc-shaped convex section, so that water flows into the water tank 41 along the surface of the diversion plate 44 during the water adding process.

Further, the above-described water tank 41 may be provided to be detachably mounted to the inside of the case 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 replenishing pipe 42. When the water tank 41 is removed, the valve is closed to avoid leakage. The valve 43 may be a mechanical valve, for example, a sleeve end and a plug end of a self-locking quick-release joint are respectively disposed on the water tank 41 and a fixing plate on which the water tank 41 is placed. The valve 43 may also be an electrically operated valve, such as a solenoid valve, an electrically operated valve, a pneumatic valve, etc. Thereby facilitating the disassembly of the water tank. The adjustment can be carried out by a person skilled in the art according to the actual situation.

The foregoing description is only exemplary of the preferred embodiments of the disclosure and is illustrative of the principles of the technology employed. It will be appreciated by those skilled in the art that the scope of the invention in the embodiments of the present disclosure is not limited to the specific combination of the above-mentioned features, but also encompasses other embodiments in which any combination of the above-mentioned features or their equivalents is made without departing from the inventive concept as defined above.
