For example, the humidifier of the present invention may be configured as an ultrasonic humidifier, an evaporative humidifier, or a vaporizer. The humidifier of the present invention may be communicated with a
terminal device 100, such as a smartphone or a tablet computer, through wireless or wired network. A basic structure of theterminal device 100 may be illustrated inFIG. 10 of the drawings, in which theterminal device 100 may comprise acentral processor 101, a storage unit 102 and awireless transceiver 103. - Referring to
FIG. 2 andFIG. 4 toFIG. 5 of the drawings, thebase 2 may store a predetermined amount of in thewater accommodating compartment 21. The water may be supplied from thewater tank 1 when thewater tank 1 is detachably attached on thebase 2. - The
water tank 1 may comprise aninner tank member 11 and anouter tank member 12. Theinner tank member 11 may be received and protected within theouter tank member 12, wherein thewater storage cavity 111 may be formed in theinner tank member 11 for storing a predetermined amount of water, while the first waterlevel sensing device 3 may be provided on theinner tank member 11. - The
water tank 1 may be detachably attached on thebase 2 and when this happens, the water stored in thewater storage cavity 111 may be guided to flow into thewater accommodating compartment 21 for use by thewater vaporizing mechanism 30. - In order to refill water in the
water tank 1, thewater tank 1 may further comprise anopening 121 communicating thewater storage cavity 111 with an exterior thereof, and awater cap 120 detachably attached on thewater tank 1 at theopening 121 for detachably covering theopening 121. A user may be allowed to refill water to thewater storage cavity 111 through thewater opening 121. - Referring to

The securingslots 122 and the securingmembers 24 may be arranged to secure the position of thewater tank 1 on top of thebase 2. Note that the positions of the securingslots 122 and the securingmembers 24 may be interchanged. - The
water vaporizing mechanism 30 may comprise awater atomizer 301 provided in thebase 2, wherein the water stored in thewater accommodating compartment 21 may be arranged to be atomized by thewater atomizer 301. In this scenario, the humidifier of the present invention may be configured as an ultrasonic humidifier. - Alternatively, the
water vaporizing mechanism 30 may comprise aheating element 301′ for heating the water in thewater accommodating compartment 21 in a controlled manner. The water may then be slowly evaporated and blew out of the humidifier though themist discharge channel 15 and themist discharge outlet 13. In this scenario, the humidifier of the present invention may be configured as an evaporative humidifier. It is important to mention that other mechanisms by which the water is vaporized are also possible. - The first water
level sensing device 3 may comprise a plurality of firstwater level sensors 301 spacedly provided on an exterior surface of theinner tank member 11 of the water tank 10. As shown inFIG. 2 of the drawings, the firstwater level sensors 301 may be provided as an array and may be distributed along a vertical direction of theinner tank member 11, wherein a position of each of the firstwater level sensor 301 may correspond to a corresponding water level in thewater storage cavity 111. For example, when the bottommost firstwater level sensor 301 detects water and the second bottommost firstwater level sensor 301 does not detect water, the actual water level in thewater storage cavity 111 may be estimated to be somewhere between the bottommost firstwater level sensor 301 and the second bottommost firstwater level sensor 301. - Note that when the water tank 10 has only a single tank member, the first
water level sensors 301 may be provided on an exterior surface of the water tank 10. - Referring to
FIG. 3 of the drawings, each of the firstwater level sensor 301 may comprise afirst sensing member 33 and afirst sensor circuitry 31. Thefirst sensing member 33 may be configured from metallic material such as copper and may be attached on a desirable position on an exterior surface of theinner tank member 11. As shown inFIG. 3 of the drawings, terminal “KEY 1” may be electrically connected to the corresponding first sensingmember 33. - When water in the
water storage cavity 111 reaches a level corresponding to afirst sensing member 33, thefirst sensing member 33 and the water may form a capacitance which may generate a very small current to thefirst sensor circuitry 31. This small current may be detected by thefirst sensor circuitry 31 so as to ascertain the water level in thewater storage cavity 111. - The
first sensor circuitry 31 may comprise anamplifier 312 electrically connected to thefirst sensing member 33 and thecentral processing unit 50. Thecentral processing unit 50 may comprise a microprocessor (MCU 311) electrically connected to theamplifier 312 which may be configured to amplify the very small electrical current generated by the detection of the water. This very small electrical current may be transmitted to theMCU 311 for further processing and analyzing. - It is worth mentioning that each of the
first sensor circuitries 31 may be connected to aMCU 311. In this scenario, thecentral processing unit 50 may comprise a plurality ofMCUs 311 electrically connected to thefirst sensor circuitries 31 respectively. As an alternative configuration, thecentral processing unit 50 may comprise asingle MCU 311 connected to all theamplifiers 312 of thefirst sensor circuitries 31. In other words, allamplifiers 312 may share asingle MCU 311 in this alternative configuration. - Each of the first
water level sensors 301 may further comprise an indicatinglight 32 electrically connected to the correspondingfirst sensor circuitry 31 and thecentral processing unit 50, in such a manner that when thefirst sensor circuitry 31 detects water as described above, thecentral processing unit 50 may be arranged to drive the indicating light 32 to illuminate so as to signal that the water in thewater storage cavity 111 has reached a level corresponding to the height of the corresponding first sensingmember 33. - The indicating
light 32 may be electrically connected to the correspondingMCU 311 of thecentral processing unit 50. In the case that thefirst sensor circuitries 31 share asingle MCU 311, all the indicatinglights 32 may be electrically connected to thesingle MCU 311 which may individually activate or deactivate each of the indicating lights 32. - As shown in
FIG. 2 ,FIG. 4 andFIG. 5 of the drawings, the water control arrangement 40 may further comprise a main Circuit Board (main PCB 22), wherein thefirst sensor circuitries 31 and thecentral processing unit 50 may be implemented on themain PCB 22 which may be securely supported in a water-sealedcompartment 220 in thebase 2 for better protection. Thefirst sensing members 33 may be provided on theinner tank member 11 while thefirst sensor circuitries 31 may be supported in thebase 2. - In order to facilitate electrical connection between the
first sensing members 33 and thesensor circuitries 31, the water control arrangement 40 may further comprise aconnection device 5 comprising a first connection Printed Circuit Board (first connection PCB 52) and a second connection Printed Circuit Board (second connection PCB 53). As shown inFIG. 4 andFIG. 5 of the drawings, thefirst connection PCB 52 may be supported in the water-sealedcompartment 220 of thebase 2, while thesecond connection PCB 53 may be supported at alower portion 14 of thewater tank 1. Theconnection device 5 may further comprises a plurality of (at least one) connectingmembers 51 electrically connecting between thefirst connection PCB 52 and thesecond connection PCB 53 when thewater tank 1 is detachably attached on thebase 2. Thefirst connection PCB 52 may be electrically connected to themain PCB 22. - As shown in
FIG. 5 of the drawings, thewater tank 1 may further comprise a sealingcover 6 provided at thelower portion 14 for forming asealing compartment 61 within the sealingcover 6. The sealingcover 6 may be attached on thebottom panel 12 within theinner tank member 11 through at least one connectingmember 124 so as to form a sealing structure for preventing water in thewater storage cavity 111 from entering thesealing compartment 6. According to the preferred embodiment of the present invention, thesecond connection PCB 53 may be supported within thesealing compartment 6 at thelower portion 14 of thewater tank 1 so as to be securely protected from water damage. Moreover, thewater tank 1 may further have a reinforcingportion 123 supporting thesecond connection PCB 53. - Specifically, each of the connecting
members 51 may be configured from metallic material (i.e. electrical conductor) and may be attached on thefirst connection PCB 52. The connectingmembers 51 may be arranged to physically contact with thesecond connection PCB 53 when thewater tank 1 is detachably attached on thebase 2. - The second
water sensing device 4 may comprise at least one second water level sensor 41 provided on thebase 2. The second water level sensor 41 may comprise asecond sensing member 411 and asecond sensor circuitry 412. The second water level sensor 41 may be provided on an exterior surface of thewater accommodating cavity 21. The second water level sensor 41 may operate in a manner similar to the firstwater level sensor 301 as described above. Thus, referring toFIG. 12 of the drawings, the second water level sensor 41 may comprise asecond sensing member 411 and asecond sensor circuitry 412. Thesecond sensing member 411 may be configured from metallic material such as copper and may be attached on a desirable position on an exterior surface of thewater accommodating cavity 21. As shown inFIG. 12 of the drawings, terminal “KEY 1” may be electrically connected to the correspondingsecond sensing member 411. - When water in the
water accommodating cavity 21 reaches a level corresponding to asecond sensing member 411, thesecond sensing member 411 and the water may form a capacitance which may generate a very small current to thefirst sensor circuitry 412. This small current may indicate that the water in thewater accommodating cavity 21 does not fall below a predetermined threshold. - Note that the
second sensor circuitry 412 may also be connected to thecentral processing unit 50. Thus, thesecond sensor circuitry 412 may comprise anamplifier 4122 electrically connected to thesecond sensing member 411 and electrically connected to at least oneMCU 311 of thecentral processing unit 50. Theamplifier 4122 may be configured to amplify very small electrical current generated by the detection of the water by thesecond sensing member 411. When the water in thewater accommodating cavity 21 falls below thesecond sensing member 411, the small current ceases to exist and theMCU 311 may be arranged to deactivate thewater vaporizing mechanism 30 so as to prevent overheating of the dehumidifier of the present invention. - Note that the
first sensor circuitries 31 and thesecond sensor circuitry 412 may be implemented on themain PCB 22 so that they may be well protected in a water-sealed environment in thebase 2. The signal received by thefirst sensing members 33 may be transmitted to thefirst sensor circuitries 31 on themain PCB 22. Similarly, the signal received by thesecond sensing member 411 may also be transmitted tosecond sensor circuitry 412 also implemented on themain PCB 22. - Note that, depending on the circumstances in which the present invention is manufactured and to be utilized,
central processing unit 50 may comprise a plurality ofMCUs 311 so that each of thefirst sensor circuitries 31 and thesecond sensor circuitry 412 may have anindividual MCU 311. Alternatively, thefirst sensor circuitries 31 and thesecond sensor circuitry 412 may share a single MCU so that thecentral processing unit 50 may need to only comprise oneMCU 311, to which all thefirst sensor circuitries 31 and thesecond sensor circuitry 412 may be connected. - Moreover, the
MCU 311 of thecentral processing unit 50 may be configured or programed to deactivate thewater vaporizing mechanism 30 when the second waterlevel sensing device 4 detects that the water in the water-accommodatingcompartment 21 of thebase 2 has fallen below a predetermined threshold. - The
central processing unit 50 may further comprise acommunication module 312 electrically connected to theMCU 311 for transmitting and receiving signals through a predetermine wireless or wired network. Thecommunication module 312 may be configured to send a corresponding signal to theterminal device 100 through the wireless or wired network. - It is worth mentioning that as slight variations of the preferred embodiment, each of the
first sensor circuities 31, thesecond sensor circuitries 411 may be implemented on themain PCB 22, thefirst connection PCB 52 or thesecond connection PCB 53. - Referring to
FIG. 6 of the drawings, thebase 2 may further have a plurality of throughholes 232 formed on thetop panel 23 for allowing the connectingmembers 51 to pass therethrough. The connectingmembers 51 may therefore extend from thefirst connection PCB 52 to thesecond connection PCB 53 through the throughholes 232. Furthermore, thebase 2 may further have a plurality of partitioningridges 231 formed on thetop panel 23 for separating each of the throughholes 232. When thewater tank 1 is attached on or detached from thebase 2, a small amount of water may stay on thetop panel 23. The purpose of separating the throughholes 232 is to prevent such small amount of water from contacting with the all the connectingmembers 51 so as to minimize the chance of short circuit between the connectingmembers 51. Thebase 2 may further have a plurality of guidinggrooves 233 formed on thetop panel 23, wherein the guidinggrooves 233 may extend from the partitioningridges 231 for guiding water staying on thetop panel 23 to flow away from the throughholes 232. Thus, each of the guidinggrooves 233 may extend from the corresponding throughhole 232 to a peripheral portion of thebase 2 so as to guide the water to flow away from the throughhole 232. - The
communication module 312 of thecentral processing unit 50 may also be implemented on themain PCB 22 and may be configured to communicate with theterminal device 100 through wired or wireless communication, such as through wireless Internet network. Thus, thecommunication module 312 may comprise atransceiver 3121 which support popular wireless communication protocols such as ultra high frequency (UHF) short radio wave transmission protocol (e.g. BLUETOOTH), a wireless network protocol (e.g. WIFI) etc. The connection between thecommunication module 312 and theterminal device 100 may be through aserver 500. - The
communication module 312 may be arranged to transmit information about water level in thewater storage cavity 111 and/or thewater accommodating compartment 21 to theterminal device 100 or through apredetermined server 500. The water level information may be accompanied by warning signal advising a user of the present invention to refill water when the water level in thewater storage cavity 111 and/or thewater accommodating compartment 21 falls below a predetermined threshold. - The water control arrangement 40 may further comprise at least one speaker 43 mounted in the
base 2 and electrically connected to themain PCB 22 and themicroprocessor 311.

storage device 70 may be a conventional storage medium, such as a hard drive, flash drive, or any other storage mediums for storing data. - Referring to
FIG. 7 of the drawings, the present invention may also provide a method of monitoring and controlling water volume in a humidifier through aterminal device 100, comprising the steps of: - (a) receiving, by the
terminal device 100, a water level and a corresponding water volume of awater storage cavity 111 of awater tank 11 of a humidifier, wherein the water level may be detected by a first waterlevel sensing device 3 of the humidifier; - (b) receiving, by the
terminal device 100, a water level and a corresponding water volume of awater accommodating compartment 21 ofbase 2 of a humidifier, wherein the water level may be detected by a second waterlevel sensing device 4 of the humidifier; - (c) acquiring a remaining total water volume of the humidifier by adding the water volume of the
water storage cavity 111 and thewater accommodating compartment 21; and - (d) alerting a user of the humidifier to refill water in the
water storage cavity 111 when the remaining water volume of the humidifier falls below a predetermined threshold. - In step (a) above, the water volume of the
water storage cavity 111 may be calculated by the water level detected by the first waterlevel sensing device 3. Similarly, the water volume of thewater accommodating compartment 21 may be calculated by the water level detected by the second waterlevel sensing device 4. The calculation of the water volume in thewater storage cavity 111 and thewater accommodating compartment 21 may be performed in theCPU 50 of the humidifier, in the properly-programedterminal device 100, or in theserver 500. - In step (a) and step (b), the water level or the corresponding water volume in the
water storage cavity 111 of thewater tank 1 and thewater accommodating compartment 21 of the base may be wirelessly transmitted to theterminal device 100 through the predetermined network described above. Moreover, in step (a) and step (b) above, theterminal device 100 may acquire the water volume of thewater storage cavity 111 of thewater tank 1 and the water volume of thewater accommodating compartment 21 of the base directly from thecommunication module 312 of the humidifier, or from a server wirelessly connected to the humidifier. - As mentioned above, the wireless communication between the
communication module 3121 of thecentral processing unit 50 and theterminal device 100 may be accomplished by typical wireless communication protocols such as ultra high frequency (UHF) short radio wave transmission protocol (e.g. BLUETOOTH), a wireless network protocol (e.g. WIFI) etc. - Step (a) through step (c) may be performed at a predetermined time interval so that the remaining total water volume of the humidifier may be periodically monitored so that water may be refilled into the
water storage cavity 111 in time. This predetermined time interval may be pre-set by the manufacturer of the present invention, or by a user through theterminal device 100 by using a designated software. - The method of monitoring and controlling water volume in a humidifier may further comprise a step, in between step (c) and step (d), of displaying, by the
terminal device 100, the remaining water volume of the humidifier. Theterminal device 100 may display the remaining water volume of the humidifier through a built-in display screen or through an external display connected to theterminal device 100. The remaining water volume of the humidifier may be displayed to the user of the present invention through texts, graphics, or a combination of texts and graphics. For example, if the maximum remaining water volume of the humidifier is 5000 ml, and the actual remaining water volume of the humidifier is 2300 ml, a 46% colored-filled portion of a whole graphical element (e.g. a humidifier) may graphically represent the remaining water volume of the humidifier. - In step (d), the predetermined threshold for alerting refill may be pre-set by manufacturer of the present invention. Alternatively, the threshold may be set by the user of the present invention through the
terminal device 100 by using a designated software. The alert for the user may be in the form of an audible sound generated by at least one of theterminal device 100 or the humidifier. - The method of monitoring and controlling water volume in a humidifier may further comprise a step (e) of determining, by at least one of the
terminal device 100 and theserver 500, a water dissipating rate of the humidifier. - The water dissipating rate of the humidifier is closely related to the operation of the humidifier. For example, the humidifier of the present invention may be configured to have three operational modes (such as high, medium, low) which correspond to three different mist setting. When the humidifier is set as high mist operational mode, the humidifier may discharge the highest amount of mist and the water dissipating rate will the highest. When the humidifier is set as low mist operational mode, the humidifier may discharge the smallest amount of mist and the water dissipating rate will be the lowest. The medium mist operational mode is somewhere between the high mist operational mode and the low mist operational mode.
- As a result, the
terminal device 100 or the server may determine a corresponding water dissipating rate of the humidifier. For example, when the humidifier is set as high mist operational mode, the water dissipating rate may be 500 ml/hour, and when the humidifier is set as low mist operational mode, the water dissipating rate may be 100 ml/hour, and when the humidifier is set as medium mist operational mode, the water dissipating rate may be 300 ml/hour. Theterminal device 100 or theserver 500 may determine the water dissipating rate by detecting the operational mode of the humidifier. - Note that the water dissipating rate of the humidifier for each of the operational modes may be determined by a pre-set parameter from the manufacturer. Alternatively, the water dissipating rate may be calculated by actual water dissipation in the humidifier as detected by the first water
level sensing device 3 and the second waterlevel sensing device 4. During a particular operational mode, the water level in thewater storage cavity 111 and thewater accommodating compartment 21 may be detected in regular intervals (such as 1-minute interval) so as to determine the remaining total water volume of the humidifier before and after the interval. After that, the water dissipating rate may be calculated by dividing the difference between the remaining total water volume of the humidifier by the time interval. For example, the remaining total water volume before a 1-minute interval is 3005 ml and after the 1-minute interval is 3000 ml. The water dissipating rate may be calculated as 3005 ml−3000 ml=5 ml per minute. - The method of monitoring and controlling water volume in a humidifier may further comprise a step (f) of determining a remaining operation time of the humidifier based on the remaining total water volume and the water dissipating rate of the humidifier obtained in step (e), and displaying the remaining operation time on the
terminal device 100. - The remaining operating time of the humidifier may be determined by dividing the remaining total water volume by the water dissipating rate obtained in step (e) above. For example, when the remaining total water volume is 3000 ml, and the water dissipating rate is 300 ml/hour, the remaining operating time is 3000/300=10 hours.
- In step (f) above, the remaining operation time may be periodically updated when the operational mode of the humidifier changes. Thus, step (f) may comprise a step of periodically updating the remaining operation time when the operational mode of the humidifier changes. Since different operational mode may cause different water dissipating rate, when the operational mode changes (such as from low to medium), the water dissipating rate may increase and the remaining operation time of the humidifier may decrease due to the change in the operational mode.
- The method of monitoring and controlling water volume in a humidifier may further comprise a step (g) of deactivating, by the
CPU 50, thewater vaporizing mechanism 30 of the humidifier when the water volume of thewater accommodating compartment 21 ofbase 2 falls below a predetermined threshold. - From the forgoing descriptions, one skilled in the art may appreciate that the
terminal device 100 may alert the user for refilling water when the water in thewater storage cavity 111 falls below a predetermined threshold. Moreover, theCPU 50 of the humidifier may deactivate thewater vaporizing mechanism 30 when the water in thewater accommodating compartment 21 falls below another predetermined threshold. - Alternatively, the deactivation of the
water vaporizing mechanism 30 may also be triggered when theCPU 50 or theterminal device 100 determines that the remaining operation time of the humidifier may be less than a predetermined threshold, such as 5 minutes. - Referring to
FIG. 8 of the drawings, an alternative mode of the method of monitoring and controlling water volume in a humidifier through aterminal device 100 is illustrated. In this alternative mode, the method of monitoring and controlling water volume in a humidifier may comprise the steps of: - (1) receiving, by the
terminal device 100, a water volume of awater storage cavity 111 of awater tank 11 of a humidifier, wherein the water volume of thewater storage cavity 111 may be obtained by a water level detected by a first waterlevel sensing device 3 of the humidifier; - (2) receiving, by the
terminal device 100, a water volume of awater accommodating compartment 21 ofbase 2 of a humidifier, wherein the water volume of thewater accommodating compartment 21 may be obtained by a water level detected by a second waterlevel sensing device 4 of the humidifier; - (3) acquiring a water dissipating rate of the humidifier; and
- (4) acquiring a remaining operation time of the humidifier based on the water volume of the
water storage cavity 111, the water volume of thewater accommodating compartment 21, and the water dissipating rate. - In step (3), as mentioned earlier, the water dissipating rate of the humidifier is closely related to the operation of the humidifier. For example, the humidifier of the present invention may be configured to have three operational modes (such as high, medium, low) which correspond to three different mist setting. The
terminal device 100 or the server may determine or detect a corresponding water dissipating rate of the humidifier. - The method of monitoring and controlling water volume in a humidifier may further comprise a step of displaying, by the
terminal device 100, the remaining operation time of the humidifier. Theterminal device 100 may display the remaining operation time of the humidifier through a built-in display screen or through an external display connected to theterminal device 100. The remaining operation time of the humidifier may be displayed to the user of the present invention through texts, graphics, or a combination of texts and graphics. - Step (2) may comprise the steps of:
- (2.1) setting the water volume of the
water accommodating cavity 21 to be maximum when the water volume of thewater storage cavity 111 is greater than zero; - (2.2) when the water volume of the
water storage cavity 111 is equal to or greater than zero, detecting, by a second waterlevel sensing device 4, a water level in thewater accommodating cavity 21; and - (2.3) acquiring the water volume of the
water accommodating cavity 21 based on the detected water level in thewater accommodating cavity 21. - The method of monitoring and controlling water volume in a humidifier through a
terminal device 100 may further comprise a step (5) of alerting a user of the humidifier to refill water in thewater storage cavity 111 when the remaining operation time of the humidifier falls below a predetermined threshold. - The method of monitoring and controlling water volume in a humidifier through a
terminal device 100 may further comprise a step, in between step (4) and step (5), of acquiring a water volume of thewater accommodating compartment 21 based on the maximum water volume of thewater accommodating compartment 21, the water dissipating rate, and the time lapsed after the water volume of thewater storage cavity 111 becomes zero. - In this situation, step (5) may alert a user of the humidifier to refill water in the
water storage cavity 111 when at least one of the remaining operation time and the water level in thewater accommodating compartment 21 of the humidifier falls below a predetermined threshold. - The method of monitoring and controlling water volume in a humidifier through a
terminal device 100 may further comprise a step (6) of deactivating thewater vaporizing mechanism 30 when the remaining operation time of the humidifier falls below a predetermined threshold. The remaining operation time may be pre-set by the manufacturer or by the user through theterminal device 100. - Embodiments of the present disclosure, while illustrated and described in terms of disclosed embodiments and several alternatives, is not limited to the particular description contained in this specification. Additional alternative or equivalent components could also be used to practice embodiments of the present disclosure.
