Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A dual chamber humidifier according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

The first embodiment is as follows:

the invention provides a dual-chamber humidifier, comprising:

the ultrasonic atomization device comprises a shell 1, wherein an evaporation cavity 2 and an ultrasonic atomization cavity 13 are arranged in the shell 1, and a water outlet 13.2 of the ultrasonic atomization cavity 13 is communicated with a water inlet 2.1 of the evaporation cavity 2;

the air outlet 3 is arranged on the shell 1 and is communicated with the evaporation cavity 2, so that the air in the evaporation cavity 2 is allowed to be pumped out of the shell 1 through the air outlet 3;

a fog discharge port 15 which is arranged on the shell 1 and is communicated with the evaporation cavity 2 through a fog discharge pipeline 14, so that the air in the ultrasonic atomization cavity 13 is allowed to be discharged out of the shell 1 through the fog discharge port 15

The water tank 4 is arranged on the shell 1, and a water outlet end 4.1 of the water tank 4 is communicated with a water inlet 13.1 of the ultrasonic atomization cavity 13, so that the water tank 4 can deliver water to the ultrasonic atomization cavity 13 at intervals;

a fan assembly 5 installed in the housing 1 for increasing the air flow rate of the air outlet 3;

it is characterized by also comprising:

an evaporation humidification screen 6, wherein the bottom of the evaporation cavity 2 is provided to be capable of retaining liquid, and the bottom area of the evaporation humidification screen 6 in the vertical direction is partially immersed in the liquid;

a floater 24.1 capable of floating on the water surface is arranged in the evaporation cavity 2, a water outlet pipe 24.2 is arranged on the floater 24.1, an upper end pipe orifice of the water outlet pipe 24.2 is positioned above the floater 24.1, and a lower end pipe orifice of the water outlet pipe 24.2 is communicated with the water inlet hole 2.1 through a hose 24.3.

With regard to the float 24.1, the outlet pipe 24.2 and the hose 24.3 provided in the evaporation chamber 2, the present embodiment takes into account: because the liquid level in the ultrasonic atomization chamber 13 and the atomization plate in the ultrasonic atomization chamber 13 need to be kept at a relatively proper position in the ultrasonic atomization process to enable the atomization plate to work normally, i.e. too low or too high a liquid level, will cause the atomizing plate to fail, and, at the same time, the liquid level in the evaporation chamber 2 needs to be maintained at a suitable level, namely, too high liquid level can submerge more evaporation humidification nets 6, the effective working area of the evaporation humidification nets 6 is reduced, and the low liquid level can make the evaporation humidification net 6 have poor water absorption effect, at this time, because the ultrasonic atomization cavity 13 and the evaporation cavity 2 have certain limits on the liquid level height in the respective cavities, therefore, when the installation positions of the ultrasonic atomization chamber 13 and the evaporation chamber 2 are limited due to the avoidance of the internal space, the problem of how to make the liquid level of the liquid in the ultrasonic atomization chamber 13 higher than the liquid level of the liquid in the evaporation chamber 2 is faced. For this reason, the present embodiment is improved in that: and a switch component 24 which can be used for controlling the water feeding amount of the ultrasonic atomization cavity 13 towards the evaporation cavity 2 is arranged on the connecting water pipe 21, so that the liquid level in the ultrasonic atomization cavity 13 is higher than that in the evaporation cavity 2.

As to the ultrasonic atomization chamber, the purpose is to meet different requirements of customers for evaporation humidification and ultrasonic humidification, so that the embodiment has both evaporation humidification and ultrasonic humidification, the shell 1 is internally provided with an ultrasonic atomization chamber 13 and a mist discharge pipeline 14 which are arranged adjacent to the evaporation chamber 2, one end of the mist discharge pipeline 14 is communicated with the ultrasonic atomization cavity 13, the other end is communicated with a mist discharge port 15 on the outer surface of the shell 1, so that the air in the ultrasonic atomization cavity 13 can be delivered to the outside of the shell 1 through the mist discharge pipeline 14 and the mist discharge port 15, the atomization sheet 16 is arranged in the ultrasonic atomization cavity 13, the ultrasonic atomization device is used for atomizing liquid in the ultrasonic atomization cavity 13 through ultrasonic vibration, a mist exhaust fan 17 used for driving air in the ultrasonic atomization cavity 13 to flow towards a mist exhaust port 15 is arranged in the shell 1, and a water tank used for supplementing liquid towards the ultrasonic atomization cavity 13 is arranged on the shell 1.

The adjacent arrangement is understood that the evaporation chamber 2 and the ultrasonic atomization chamber 13 are two independent chambers, and are arranged in the shell 1, and are not limited to be adjacent to each other.

Of course, the above-mentioned requirement for vibration of the atomizing plate 16 requires a controller connected thereto, and the controller provides the power required for vibration of the atomizing plate 16 and controls the start and stop of the atomizing plate 16. It should be understood that the ultrasonic atomizer formed by the controller and the atomizing plate 16 is a common component in the field of ultrasonic atomization, and thus the specific structure and connection relationship thereof need not be described in detail, and the controller is disposed in the housing 1.

Further, as shown in fig. 11, the switch assembly 24 comprises a float 24.1, an outlet pipe 24.2 and a hose 24.3, wherein the outlet pipe 24.2 is fixed on the float 24.1, the upper end nozzle of the outlet pipe 24.2 is suspended above the float 24.1, the lower end of the outlet pipe 24.2 is communicated with one end of the hose 24.3, and the other end of the hose 24.3 is communicated with the connecting water pipe 21. At this time, the floater 24.1 floats on the liquid level in the evaporation cavity 2 and moves in the vertical direction along with the rise and fall of the liquid level in the evaporation cavity 2, when the upper end pipe orifice of the water outlet pipe 24.2 on the floater 24.1 is flush with the liquid level in the ultrasonic atomization cavity 13 in the process that the floater 24.1 moves up and down, the upper end pipe orifice of the water outlet pipe 24.2 on the floater 24.1 stops discharging water, and when the upper end pipe orifice of the water outlet pipe 24.2 on the floater 24.1 is lower than the liquid level in the ultrasonic atomization cavity 13, the liquid in the ultrasonic atomization cavity 13 flows into the evaporation cavity 2 through the connecting water pipe 21, the hose 24.3 and the water outlet pipe 24.2 in sequence. As shown in fig. 8 and 11, after the upper end pipe orifice of the water outlet pipe 24.2 rises to be flush with the liquid level in the ultrasonic atomization chamber 13 along with the float 24.1, the water in the ultrasonic atomization chamber 13 does not continuously flow into the evaporation chamber 2 through the water outlet pipe 24.2, at this time, the liquid level H2 in the ultrasonic atomization chamber 13 is higher than the liquid level H1 in the evaporation chamber 2, and after the water in the evaporation chamber 2 is continuously evaporated, the liquid level H1 in the evaporation chamber 2 is reduced to drive the water outlet pipe 24.2 to automatically lower, and at this time, the ultrasonic atomization chamber 13 can automatically supplement water in the super evaporation chamber 2. Therefore, the liquid level of the liquid in the evaporation cavity 2 and the liquid level of the liquid in the ultrasonic atomization cavity 13 can be always kept at a constant height difference in the embodiment through the design of the switch assembly 24, and the switch assembly 24 does not need additional signal control and sensors, so that the structure is stable, and the cost is low.

Further, the switch assembly 24 also comprises a guide rod 24.4, the guide rod 24.4 is fixed in the evaporation cavity 2 in an upright state, and the float 24.1 is in sliding fit with the guide rod 24.4. Float 24.1 can be guided by guide rod 24.4.

Regarding the housing 1 and the air outlet 3, specifically, as shown in fig. 1 and fig. 2, the top of the housing 1 is open, an evaporation chamber 2 is provided in the housing 1, and an upper port of the evaporation chamber 2 extends upward and forms an air outlet 3 at the top of the housing, the open port at the top of the housing 1 is covered with a screen plate, and the air outlet 3 can discharge mist through the mesh holes of the screen plate, and can play a role of protection through the screen plate.

The fan assembly 5 is preferably integrated in the channel between the evaporation chamber 2 and the air outlet 3, and the fan assembly 5 accelerates the air flow in the channel, so as to draw the humid air in the evaporation chamber 2 out of the housing 1 from the air outlet 3.

The water tank 4 is arranged on the shell 1 and is used for supplementing water for generating steam and mist to the ultrasonic atomization cavity 13 and the evaporation cavity 2, and the evaporation speed of the water in the ultrasonic atomization cavity 13 and the evaporation cavity 2 is related to factors such as the power of the atomization sheet, the external environment humidity, the output power of the fan assembly 5, the cross-sectional area of the evaporation cavity 2 and the use frequency of a user, so that the water supplemented into the ultrasonic atomization cavity 13 by the water tank 4 also needs to be delivered at intervals based on the water shortage requirement. Of course, to realize the intermittent water supply from the water tank 4 to the ultrasonic atomization chamber 13 according to the requirement, the intermittent water supply can be realized by controlling the electromagnetic valve switch on the water tank 4 through the controller, or the automatic switch of the valve on the water tank 4 can be realized based on the reduction of the water level in the evaporation chamber 2, and whether the water tank 4 can supply water to the ultrasonic atomization chamber 13 in an intermittent water supply manner through an active electromagnetic control manner or a passive manner of passive opening and closing of the mechanical valve itself, it should be understood that the intermittent water supply from the water tank 4 can be realized. Moreover, the related controller and the electromagnetic valve that the water tank 4 can alternately discharge water are common prior art in the field of humidifiers, so that the specific structure of each component is not repeated.

Specifically, the water outlet end 4.1 of the water tank 4 is communicated with the water inlet 13.1 of the ultrasonic atomization cavity 13, the water outlet 13.2 of the ultrasonic atomization cavity 13 is communicated with the water inlet hole of the evaporation cavity 2, and the water outlet end 4.1 of the water tank 4 is provided with a valve 22 for opening and closing the water outlet end 4.1. Thus, only one water outlet end 4.1 and the valve 22 are reserved on the water tank 4, and the liquid entering the ultrasonic atomization chamber 13 flows into the evaporation chamber 2 again through the connecting water pipe 21.

Preferably, the water outlet 13.2 is disposed at the bottom of the ultrasonic atomization chamber 13, and the water inlet 2.1 of the evaporation chamber 2 is disposed at the bottom of the evaporation chamber 2, so that the liquid in the ultrasonic atomization chamber 13 can smoothly flow into the evaporation chamber 2 based on its own weight. Preferably, the water outlet 13.2 of the ultrasonic atomization cavity 13 is communicated with the water inlet 2.1 of the evaporation cavity 2 through a connecting water pipe 21.

Example two:

based on the improvement of the implementation, the difference lies in that: the evaporation humidification net 6 is of a cylindrical structure, the evaporation humidification net 6 is in running fit with the shell 1 around the axis of the evaporation humidification net 6, and the axis of the evaporation humidification net 6 is arranged in the horizontal direction.

Certainly, in this embodiment, the evaporation humidification network 6 is rotationally matched with the housing 1, and the cylindrical evaporation humidification network 6 needs to be rotated and needs a driving component, so that the above embodiment implicitly discloses that a driver for driving the evaporation humidification network to rotate is arranged in the housing, and the driver can be a special motor (not shown in the figure) which is separately used for driving the evaporation humidification network to rotate; or may share a drive with the fan assembly, thereby saving drive. (see example three, infra for this preferred embodiment)

Further, since the fan assembly 5 continuously draws the humid air in the evaporation chamber 2 out of the housing 1 from the air outlet 3, the housing should have an air inlet 10 on the side wall of the air inlet housing. The air intake hole 10 is provided on the outer side wall of the housing 1 and communicates with the evaporation chamber 2 inside the housing 1. It should be noted that an air flow channel for air circulation is formed among the air inlet 10, the evaporation chamber 2 and the air outlet 3, and in order to improve that the relatively humid air in the area where the evaporation and humidification net 6 is located in the evaporation chamber 2 can be extracted to the maximum extent, therefore, as a preference of this embodiment, the air inlet 100 should be arranged so as to form the air flow channel, so that the air flow channel can cover the area where the evaporation and humidification net 6 is located to the maximum extent.

Further, the liquid in this embodiment includes, but is not limited to, water, and various kinds of aqueous solutions containing volatile substances.

Based on the preferred embodiment, the evaporation humidification net 6 is mounted on the water tank 7 and is rotatably engaged with the water tank 7. The evaporation humidification net 6 is arranged on the water tank, so that the evaporation humidification net 6 can be synchronously taken out of the shell 1 along with the extraction of the water tank 7, and the evaporation humidification net 6 can be conveniently cleaned, overhauled and replaced.

Specifically, as shown in fig. 10 and 11, a semicircular groove 7.1 with an upward opening is formed in the side wall of the water tank 7, and protruding shafts are arranged at two ends of the evaporation humidification net 6 and can be clamped into the semicircular groove from top to bottom under the action of gravity of the evaporation humidification net, so that the evaporation humidification net 6 and the water tank 7 can be conveniently installed.

Example four:

based on the improvement of the implementation, the difference lies in that:

In order to drive the rotation of the evaporation humidification screen 6 and the rotation of the fan wheel 5.1 simultaneously with fewer parts, the improvement of the embodiment is that: an output shaft 5.2.1 of the driving motor 5.2 is in transmission connection with the fan wheel 5.1 and the evaporation and humidification net 6 respectively, so that the fan wheel 5.1 and the evaporation and humidification net 6 rotate synchronously.

In order to realize that the driving motor 5.2 simultaneously drives the fan wheel 5.1 and the evaporation and humidification net 6, specifically, the driving motor 5.2 is arranged between the evaporation and humidification net 6 and the fan wheel 5.1, the driving motor 5.2 is a dual-output shaft 5.2.1 motor, the dual-output shaft motor is also called a dual-rotor motor, and has two output shafts, an annular gear ring 9 is arranged on the outer side wall of the evaporation and humidification net 6, one output shaft 5.2.1 of the dual-output shaft 5.2.1 motor is connected with the fan wheel 5.1, and the other output shaft 5.2.1 is provided with a transmission gear 8 meshed with the annular gear ring 9, so that the two output shafts 5.2.1 of the driving motor 5.2 can simultaneously drive the evaporation and humidification net 6 and the fan wheel 5.1 to rotate.

The transmission components include, but are not limited to, a transmission gear set, a belt and pulley transmission, and a worm gear transmission.

Example five:

The air sucked in through the air inlet hole 10 can enter the hollow cavity of the evaporation humidification screen 6 preferentially, so that the air can have more contact area and contact time with the evaporation humidification screen 6 in the air circulation process, and more humid air can be carried away.

Furthermore, evaporation humidification net 6 includes the skeleton, and the both ends of skeleton are equipped with protruding axle 6.1 respectively for with the semicircular groove 7.1 normal running fit on the basin 7 both ends, and the last axial along the axis at protruding axle 6.1 place of skeleton has set gradually the absorbent who is used for adsorbing liquid.
