Description

TECHNICAL FIELD

[0001] The present application relates to the field of humidification atomization technology, in particular to a humidifier and a control method thereof. BACKGROUND

[0002] The humidifier refers to a device that atomizes water into tiny droplets through high-frequency vibration to achieve humidification. To solve the water quality problem, some humidifiers use a boiling purification method, that is, the water is completely boiled by heating to kill microorganisms, and then impurities are removed by condensation to obtain pure water for atomization. However, due to the structural design of the traditional heater, the humidification is delayed, which cannot meet the user's demand for instant humidification. SUMMARY

[0003] Therefore, it is necessary to provide a humidifier and a control method thereof, which can reduce the humidification delay under the premise of meeting the water quality safety, so as to meet the user's demand for instant humidification.

[0004] A humidifier, the humidifier comprising: a housing having a water storage cavity and an atomization cavity therein; a purification device comprising a filtering mechanism and a heating and condensing mechanism, the filtering mechanism and the heating and condensing mechanism both communicating with the water storage cavity and the atomization cavity, the filtering mechanism being configured to filter water output from the water storage cavity, and the heating and condensing mechanism being configured to heat the water output from the water storage cavity into water vapor and condense the obtained water vapor; and an atomization device configured to atomize water in the atomization cavity and discharge the atomized water out of the atomization cavity.

[0005] The humidifier described above has the filtering mechanism and the heating and condensing mechanism connected between the water storage cavity and the atomization cavity, so that the filtering mechanism and the heating and condensing mechanism can be controlled to operate when the humidification is running, and the water paths between the water storage cavity, the filtering mechanism and the atomization cavity, and between the water storage cavity, the heating and condensing mechanism and the atomization cavity are kept in communication. At this time, the water in the water storage cavity enters the filtering mechanism and the heating and condensing mechanism respectively; the heating and condensing mechanism can heat and then condense the water to remove impurities in the water and improve the water quality. Before the water is discharged from the heating and condensing mechanism, the filtering mechanism filters and purifies the water, so that the purified water quickly enters the atomization cavity for atomization. In this way, the humidification delay is reduced under the premise of meeting the water quality safety, so as to meet the user's demand for instant humidification.

[0006] In some embodiments, the filtering mechanism comprises a resin filtering assembly, and the resin filtering assembly communicates with the water storage cavity and the atomization cavity, wherein the resin filtering assembly comprises ion exchange resin.

[0007] Therefore, during the filtering and purification, the ion exchange resin can adsorb calcium and magnesium ions and impurities in the water to achieve the purpose of water purification and ensure the water quality safety.

[0008] In some embodiments, the heating and condensing mechanism comprises a heating assembly and a condensing assembly in communication with the heating assembly, the heating assembly being in communication with the water storage cavity, and the condensing assembly being in communication with the atomization cavity.

[0009] Therefore, when the humidifier is turned on, water can flow into the heating assembly first, and water vapor can be formed under the heating of the heating assembly. The formed water vapor enters the condensing assembly for condensation, so that impurities in the water can be removed through heating and condensation to achieve the purpose of purification.

[0010] In some embodiments, the condensing assembly comprises a plurality of condensing assemblies, each condensing assembly being in communication with the heating assembly and the atomization cavity.

[0011] Therefore, the water vapor generated by the heating assembly can flow into each condensing assembly, so that the condensation speed of the water vapor can be accelerated and the water purification efficiency can be improved.

[0012] In some embodiments, the housing further comprises a containing cavity, the containing cavity being located between the water storage cavity and the atomization cavity, and the purification device being accommodated in the containing cavity.

[0013] Therefore, the introduction of the containing cavity facilitates the stable installation of the purification device in the housing. At the same time, the containing cavity is located between the water storage cavity and the atomization cavity, so that not only the communication of the filtering mechanism and the heating and condensing mechanism between the water storage cavity and the atomization cavity is facilitated, but also the water flow sequentially passes through the water storage cavity, the containing cavity and the atomization cavity, thereby shortening the water flow path.

[0014] In some embodiments, the housing comprises an outer shell and two partition pieces spaced apart in the outer shell along a predetermined direction, the two partition pieces dividing the inner part of the outer shell into the water storage cavity, the containing cavity and the atomization cavity distributed in sequence along the predetermined direction.

[0015] Therefore, by dividing the inner part of the outer shell into the water storage cavity, the containing cavity and the atomization cavity along the predetermined direction through the partition pieces, the structure of the housing is more simple and reasonable.

[0016] In some embodiments, the atomization device comprises an atomization assembly and an atomizing piece arranged in the atomization cavity, the atomizing piece comprising a covering part and a flow guiding part connected to the covering part, the covering part being provided with a cavity in communication with the atomization cavity, the flow guiding part being provided with a flow guiding hole in communication with the cavity, one end of the flow guiding hole away from the cavity being in communication with the outside of the atomization cavity, and the atomization assembly being arranged at least partially in the cavity and used for atomizing water in the cavity.

[0017] Therefore, during the atomization process, the atomization assembly atomizes water in the cavity, and the atomized water flows into the flow guiding hole from the cavity and is discharged outwardly through the flow guiding hole to realize stable atomization.

[0018] In some embodiments, the flow area of the cavity in the covering part is greater than the flow area of the flow guiding hole in the flow guiding part.

[0019] Therefore, this not only increases the capacity of the cavity and improves the atomization ability, but also allows the atomized water to enter the guide hole from the cavity, which can accelerate the flow rate of the mist and improve the misting effect.

[0020] In some embodiments, the atomizing device further includes a fan disposed in the cavity and used to blow the atomized water out of the atomizing cavity through the guide hole.

[0021] Therefore, it can be seen that by using a fan, the mist output speed of the humidifier can be accelerated, thereby improving the mist output effect.

[0022] In some embodiments, the humidifier further includes a water level sensor and an alarm. The water level sensor is used to obtain the water level in the water storage chamber, and the alarm is used to operate when the water level obtained by the water level sensor is lower than or reaches a preset water level.

[0023] Therefore, it can be seen that by using a water level sensor to obtain water level information in the water storage chamber in a timely manner, if the water level is lower than the preset water level, an alarm can be triggered to avoid the risk of dry burning.

[0024] A method for controlling a humidifier, using any one of the above-mentioned humidifiers, includes the following steps: controlling the heating and condensing mechanism and the filtration mechanism to be connected in a water path between the water storage chamber and the atomizing chamber; controlling the atomizing device to atomize the water in the atomizing chamber and discharge it outside the atomizing chamber; responding to the water temperature in the heating and condensing mechanism being heated to a preset temperature or detecting the output of condensate water from the heating and condensing mechanism, turning off, reducing or maintaining the water flow rate in the filtration mechanism.

[0025] The control method described above for the humidifier allows for the control of the filtration and heating / condensing mechanisms during humidification operation, maintaining water flow between the water storage chamber, filtration mechanism, and atomizing chamber, as well as between these other components. Water from the storage chamber enters both the filtration and heating / condensing mechanisms; the heating / condensing mechanism heats and condenses the water to remove impurities and improve water quality. Before the heating / condensing mechanism discharges water, the filtration mechanism purifies the water, allowing it to quickly enter the atomizing chamber for atomization. This design reduces humidification delay while ensuring water quality safety, thus meeting users' immediate humidification needs. Furthermore, when the water temperature in the heating / condensing mechanism reaches a preset temperature or when water discharge from the heating / condensing mechanism is detected, the water flow in the filtration mechanism can be shut off, reduced, or maintained.

[0041] In some embodiments, please refer to Figures 1 to 3 This application provides a humidifier, comprising: a housing 10, a purification device 20, and an atomizing device 30. The housing 10 has a water storage chamber 13 and an atomizing chamber 14. The purification device 20 includes a filtration mechanism 21 and a heating and condensing mechanism 22, both of which are connected to the water storage chamber 13 and the atomizing chamber 14. The filtration mechanism 21 filters the water output from the water storage chamber 13, and the heating and condensing mechanism 22 heats the water output from the water storage chamber 13 to water vapor and condenses the obtained water vapor. The atomizing device 30 atomizes the water in the atomizing chamber 14 and discharges it outside the atomizing chamber 14.

[0042] The humidifier described above connects a filter mechanism 21 and a heating and condensing mechanism 22 between the water storage chamber 13 and the atomizing chamber 14. This allows for control of the operation of the filter mechanism 21 and the heating and condensing mechanism 22 during humidification, maintaining water flow between the water storage chamber 13, the filter mechanism 21, and the atomizing chamber 14, as well as between the water storage chamber 13, the heating and condensing mechanism 22, and the atomizing chamber 14. Water from the water storage chamber 13 enters both the filter mechanism 21 and the heating and condensing mechanism 22. The heating and condensing mechanism 22 heats and condenses the water to remove impurities and improve water quality. Before the heating and condensing mechanism 22 discharges water, the filter mechanism 21 filters and purifies the water, allowing the purified water to quickly enter the atomizing chamber 14 for atomization. This design reduces humidification delay while ensuring water quality safety, thus meeting users' needs for immediate humidification.

[0043] It should be noted that the water storage chamber 13 and the atomizing chamber 14 are two separate spaces within the housing 10. The water storage chamber 13 is used to store water, which facilitates the delivery of water to the filtration mechanism 21 and the heating and condensing mechanism 22. The atomizing chamber 14 is used to receive the water purified by the filtration mechanism 21 and the heating and condensing mechanism 22, which facilitates the atomizing device 30 to atomize and discharge the water in the atomizing chamber 14 to achieve the purpose of humidification.

[0044] The humidifier housing 10 can be a one-piece structure or a split structure. When the heater housing 10 is a split structure, the housing 10 can include a first part and a second part, and the water storage chamber 13 and the atomizing chamber 14 can be respectively disposed in the first part and the second part. When the heater housing 10 is a one-piece structure, there are various designs for the distribution between the water storage chamber 13 and the atomizing chamber 14, such as: the water storage chamber 13 and the atomizing chamber 14 are distributed side by side with intervals; or, the water storage chamber 13 has a ring structure and surrounds the outer periphery of the atomizing chamber 14.

[0045] Furthermore, the filtration mechanism 21 refers to the filtration of water output from the water storage chamber 13 using a filtration method to remove at least some impurities and ions from the water, thereby achieving the purpose of water purification. The filtration mechanism 21 can employ various filtration methods, such as, but not limited to, ion exchange resins, microporous ceramic adsorption, and activated carbon adsorption.

[0046] The heating and condensing mechanism 22 heats water to a preset temperature to form water vapor, which is then condensed to achieve water purification. However, the heating and condensing mechanism 22 requires a relatively long time to heat the water, resulting in a delay in humidification from startup to the production of purified water. This delay fails to meet users' immediate humidification needs.

[0047] Therefore, in this embodiment, two purified water paths are introduced between the water storage chamber 13 and the atomizing chamber 14, one of which is a filtration mechanism 21 and the other is a heating and condensing mechanism 22. When the humidifier is turned on, the filtration mechanism 21 and the heating and condensing mechanism 22 can be controlled to operate simultaneously, so that the heating and condensing mechanism 22 can quickly produce purified water using the filtration mechanism 21 before producing purified water, thereby shortening the humidification delay and facilitating the meeting of users' needs for instant humidification.

[0048] The atomizing device 30 refers to a device that can atomize the water in the atomizing chamber 14 and discharge it outside the atomizing chamber 14. It can use various atomization methods, such as, but not limited to, ultrasonic atomization and compression atomization.

[0049] Additionally, it should be noted that the connection between the filter mechanism 21 and the water storage chamber 13 and the atomizing chamber 14 can be a controllable connection. For example, when the humidifier is turned on, the water storage chamber 13 and the atomizing chamber 14 can be controlled to be connected to the water path of the filter mechanism 21, allowing water to flow from the water storage chamber 13 through the filter mechanism 21 and the atomizing chamber 14 in sequence. To achieve this controllable connection, a control valve can be installed on the filter mechanism 21; or, a control valve can be installed at the connection between the filter mechanism 21 and the water storage chamber 13 and / or the atomizing chamber 14. This control valve can be of various types, such as a solenoid valve or an electric valve.

[0050] Similarly, the connection between the heating and condensing mechanism 22 and the water storage chamber 13 and the atomizing chamber 14 can be a controllable connection. For example, when the humidifier is turned on, the water storage chamber 13 and the atomizing chamber 14 can be controlled to be connected to the water path of the heating and condensing mechanism 22, so that water can flow from the water storage chamber 13 through the heating and condensing mechanism 22 and the atomizing chamber 14 in sequence. To achieve the controllable connection, a control valve can be installed on the heating and condensing mechanism 22; or, a control valve can be installed at the connection between the heating and condensing mechanism 22 and the water storage chamber 13 and / or the atomizing chamber 14.

[0051] Further, please refer to Figure 1 The filtration mechanism 21 includes a resin filter assembly 211, which connects the water storage chamber 13 and the atomizing chamber 14. The resin filter assembly 211 includes an ion exchange resin. Therefore, during filtration and purification, the ion exchange resin adsorbs calcium and magnesium ions and impurities in the water, achieving the purpose of water purification and ensuring water quality safety.

[0052] It should be noted that ion exchange resin is a high molecular polymer with a network structure, composed of an insoluble resin matrix and active groups. It can exchange ions with ions in the solution to achieve the purpose of removing ions from water.

[0053] There are several ways in which the resin filter assembly 211 can be connected between the water storage chamber 13 and the atomizing chamber 14. For example, the resin filter assembly 211 can be attached to the side wall of the water storage chamber 13 or the atomizing chamber 14, and a hole can be made between the two to facilitate the flow of water between the resin filter assembly 211 and the water storage chamber 13 or the atomizing chamber 14; or the resin filter assembly 211 can be connected to the water storage chamber 13 or the atomizing chamber 14 through a pipe.

[0054] For specific examples, please refer to Figure 1 Please refer to Figure 2 and Figure 3 The filtration mechanism 21 also includes a connecting pipe 212. Both the water storage chamber 13 and the atomizing chamber 14 have connecting ports 16 on their inner walls. The resin filter assembly 211 is connected to the connecting port 16 via the connecting pipe 212. Furthermore, to further enhance safety, the connecting pipe 212 can be made of food-grade material.

[0055] In some embodiments, please refer to Figure 2 The heating and condensing mechanism 22 includes a heating element 221 and a condensing element 222 connected to the heating element 221. The heating element 221 is connected to the water storage chamber 13, and the condensing element 222 is connected to the atomizing chamber 14. Therefore, when the humidifier is turned on, water preferentially flows into the heating element 221, where it is heated and condensed into water vapor. The condensed water vapor then enters the condensing element 222 for condensation. This heating and condensation process removes impurities from the water, achieving purification.

[0056] It should be noted that the heating component 221 refers to a device that can heat water to a preset temperature and generate steam. Its structure can vary, including, but is not limited to, electric heating elements, PTC heaters, etc. The preset temperature can be determined based on the local air pressure; for example, the preset temperature can be, but is not limited to, 95℃~100℃.

[0057] The condenser assembly 222 refers to the device that condenses the water vapor generated by the heating assembly 221. There are various condensation methods, such as water cooling, where the condenser assembly 222 can be a double-layer structure, with cooling water flowing through one layer to exchange heat with the water vapor in the other layer, thus condensing the water vapor. The cooled water after heat exchange can flow back to the water storage chamber 13. Alternatively, it can be air cooling, where the condenser assembly 222 exchanges heat with air or the airflow blown in by the fan 35.

[0058] In some specific examples, the condenser component 222 can be a spiral pipe that connects the heating component 221 and the atomizing chamber 14.

[0059] Further, please refer to Figure 3 The condensation assembly 222 includes multiple components, each of which is connected to the heating assembly 221 and the atomizing chamber 14. Therefore, the water vapor generated by the heating assembly 221 can be dispersed and flow into each condensation assembly 222, thus accelerating the condensation rate of the water vapor and improving the water purification efficiency.

[0060] The number of condenser components 222 is not limited to... Figure 3 The four shown in the image can be replaced with others. For example, the number of condenser components 222 can be two, three, five, or more. Furthermore, the distribution of the condenser components 222 can also be varied. For instance, the condenser components 222 can be arranged in a matrix on the heating component 221; or, the condenser components 222 can be distributed in multiple rings on the heating component 221.

[0061] In some embodiments, please refer to Figure 1 The housing 10 also includes a receiving cavity 15, located between the water storage cavity 13 and the atomizing cavity 14, within which the purification device 20 is housed. Thus, the inclusion of the receiving cavity 15 facilitates the stable installation of the purification device 20 within the housing 10. Furthermore, the location of the receiving cavity 15 between the water storage cavity 13 and the atomizing cavity 14 not only facilitates the connection between the filtration mechanism 21 and the heating and condensing mechanism 22 in the water storage cavity 13 and the atomizing cavity 14 respectively, but also allows water to flow sequentially through the water storage cavity 13, the receiving cavity 15, and the atomizing cavity 14, shortening the water flow path.

[0062] It should be noted that, within the receiving cavity 15, the heating and condensing mechanism 22 achieves condensation by exchanging heat with the space within the receiving cavity 15. Specifically, in some examples, the heating and condensing mechanism 22 includes a heating component 221 and a condensing component 222, both located within the receiving cavity 15. The condensing component 222 achieves condensation and cooling by exchanging heat with the air within the receiving cavity 15.

[0063] Meanwhile, in the receiving cavity 15, the number of both the filtration mechanism 21 and the heating and condensing mechanism 22 can be one or multiple. When there are multiple filtration mechanisms 21 and heating and condensing mechanisms 22, not only can the water purification capacity be improved, but the humidification speed can also be accelerated and the humidification delay can be shortened.

[0064] Further, please refer to Figure 1 The housing 10 includes an outer shell 11 and two partitions 12 spaced apart within the outer shell 11 along a predetermined direction X. The two partitions 12 divide the interior of the outer shell 11 into a water storage chamber 13, a receiving chamber 15, and an atomizing chamber 14, which are sequentially distributed along the predetermined direction X. Thus, by dividing the interior of the outer shell 11 into the water storage chamber 13, the receiving chamber 15, and the atomizing chamber 14 along the predetermined direction X using the partitions 12, the structure of the housing 10 becomes simpler and more reasonable.

[0065] The spacers 12 can be fixed within the housing 11 in various ways, such as, but not limited to, bolting, welding, snap-fitting, riveting, etc. Of course, each spacer 12 can also be an integral part of the housing 11.

[0066] Meanwhile, to facilitate the connection between the filtration mechanism 21 and the heating and condensing mechanism 22, a corresponding connection port 16 can be provided on the separator 12 so that both the filtration mechanism 21 and the heating and condensing mechanism 22 are connected to the water storage chamber 13 and the atomizing chamber 14.

[0067] In addition, dividing the internal space of the housing 11 by two partitions 12 facilitates the modular design of the entire heater and makes it easier to maintain and clean the inside of the heater.

[0068] In some embodiments, please refer to Figure 1 and Figure 4The atomizing device 30 includes an atomizing component 31 and a mist outlet 32 ​​disposed within the atomizing chamber 14. The mist outlet 32 ​​includes a covering portion 321 and a guide portion 322 connected to the covering portion 321. The covering portion 321 has a cavity 331 communicating with the atomizing chamber 14. The guide portion 322 has a guide hole 332 communicating with the cavity 331. The end of the guide hole 332 away from the cavity 331 communicates with the outside of the atomizing chamber 14. The atomizing component 31 is at least partially disposed within the cavity 331 and is used to atomize the water in the cavity 331. During the misting process, the atomizing component 31 atomizes the water in the cavity 331. The atomized water flows from the cavity 331 into the guide hole 332 and is discharged outward from the guide hole 332 to achieve stable misting.

[0069] It should be noted that the atomizing component 31 refers to the device that atomizes the water in the atomizing chamber 14, which may be, but is not limited to, ultrasonic atomizing devices, compression atomizing devices, etc. In some specific examples, the atomizing component 31 includes a piezoelectric ceramic sheet, which generates high-frequency vibrations to atomize the water in the atomizing chamber 14.

[0070] The mist outlet 32 ​​refers to the structure that directs the atomized water out of the atomizing chamber 14. It can be, but is not limited to, a tubular structure. In this example, the mist outlet 32 ​​includes a cover portion 321 and a guide portion 322. The cavity 331 in the cover portion 321 and the guide hole 332 in the guide portion 322 can form a mist outlet channel 33. Thus, when the atomizing assembly 31 atomizes the water in the atomizing chamber 14, the atomized water can be discharged out of the atomizing chamber 14 through the mist outlet channel 33 of the mist outlet 32.

[0071] It should also be noted that the water purified by the filtration mechanism 21 and / or the heating and condensing mechanism 22 enters the atomizing chamber 14; and then enters the cavity 331 from the atomizing chamber 14. A notch 34 may be provided on the cover 321, through which the cavity 331 communicates with the atomizing chamber 14, facilitating the stable entry of water from the atomizing chamber 14 into the cavity 331.

[0072] In this embodiment, a cavity 331 is introduced to separate the atomized water from the unatomized water, so that the atomized water can be discharged outward through the guide hole 332 in a more concentrated manner, thereby improving the misting efficiency.

[0073] Furthermore, the flow area of ​​the cavity 331 in the cover portion 321 can be designed to be larger than the flow area of ​​the guide hole 332 in the guide portion 322. This not only increases the capacity of the cavity 331 and improves the atomization capability, but also increases the flow velocity of the mist as the atomized water enters the guide hole 332 from the cavity 331, which is beneficial to improving the misting effect. Of course, in some other examples, the flow area of ​​the cavity 331 in the cover portion 321 can be designed to be equal to the flow area of ​​the guide hole 332 in the guide portion 322.

[0074] There are various ways to connect the cover part 321 and the guide part 322, such as, but not limited to, welding, bolting, snap-fitting, riveting, bonding, etc.; or, the cover part 321 and the guide part 322 are an integrated structure.

[0075] Further, please refer to Figure 1 and Figure 5 The flow area of ​​the cavity 331 in the covering part 321 is larger than the flow area of ​​the guide hole 332 in the guide part 322. Therefore, this not only increases the capacity of the cavity 331 and improves the atomization ability, but also accelerates the flow rate of the mist as the atomized water enters the guide hole 332 from the cavity 331, which is beneficial to improving the misting effect.

[0076] It should be noted that the shapes of the flow surfaces of the cavity 331 and the guide hole 332 can be designed in various ways. For example, the shapes of the flow surfaces of the cavity 331 and the guide hole 332 can be, but are not limited to, square, rectangle, ellipse, and circle. In some specific examples, the flow surface of the cavity 331 is rectangular, and the flow surface of the guide hole 332 is circular.

[0077] Meanwhile, the flow surface of cavity 331 refers to the cross-section perpendicular to the water flow direction in cavity 331, and the flow surface of guide hole 332 refers to the cross-section perpendicular to the water flow direction in guide hole 332. For ease of understanding, let's use... Figure 6 and Figure 7 For example, the flow area of ​​cavity 331 can be... Figure 6 The area filled with the oblique line region indicated by S1 is the flow area of ​​the guide hole 332. Figure 7 The area indicated by S2, which is filled with diagonal lines.

[0078] In some embodiments, please refer to Figure 1 and Figure 5 The atomizing device 30 also includes a fan 35, which is located in the cavity 331 and is used to blow the atomized water out of the atomizing chamber 14 through the guide hole 332. Thus, the fan 35 accelerates the mist output speed of the humidifier and improves the mist output effect.

[0079] It should be noted that, in order to ensure the stable operation of the fan 35, an opening 17 can be provided on the housing 10. The air intake end of the fan 35 is connected to the opening 17, which facilitates the intake of air from the outside and drives the atomized water to flow better into the mist outlet channel 33.

[0080] In some embodiments, the humidifier further includes a water level sensor and an alarm. The water level sensor is used to obtain the water level in the water storage chamber 13, and the alarm is used to activate when the water level obtained by the water level sensor is lower than or reaches a preset water level. Therefore, by timely obtaining the water level information in the water storage chamber 13 through the water level sensor, an alarm can be triggered if the water level is lower than the preset water level, thus avoiding the risk of dry burning.

[0081] It should be noted that the alarm device can have various structural designs, such as, but not limited to, warning lights and buzzers. The preset water level refers to the warning water level line in the water storage chamber 13. When the water level is lower than the preset level, it means that the water storage chamber 13 is approaching a water shortage state. At this time, the alarm device will notify the user to replenish water in the water storage chamber 13 in a timely manner. The specific location of the preset water level can be determined according to the actual product and user needs.

[0082] In some embodiments, please refer to Figure 8 This application provides a humidifier control method, using any of the above-mentioned humidifiers, the method comprising the following steps:

[0083] S100, the heating and condensation control mechanism 22 and the filtration mechanism 21 are all connected by water passage between the water storage chamber 13 and the atomizing chamber 14;

[0084] S200, the atomizing device 30 is controlled to atomize the water in the atomizing chamber 14 and discharge it outside the atomizing chamber 14;

[0085] S300, in response to the water temperature in the heating and condensing mechanism 22 being heated to a preset temperature or the output of condensate water from the heating and condensing mechanism 22 being detected, the water flow rate in the filtration mechanism 21 is turned off, reduced, or maintained.

[0086] The control method of the humidifier described above, using the humidifier itself, allows for the control of the filter mechanism 21 and the heating and condensing mechanism 22 during humidification operation, maintaining water flow between the water storage chamber 13, the filter mechanism 21, and the atomizing chamber 14, as well as between the water storage chamber 13, the heating and condensing mechanism 22, and the atomizing chamber 14. At this time, water in the water storage chamber 13 enters both the filter mechanism 21 and the heating and condensing mechanism 22; the heating and condensing mechanism 22 heats and condenses the water to remove impurities and improve water quality. Before the heating and condensing mechanism 22 discharges water, the filter mechanism 21 filters and purifies the water, allowing the purified water to quickly enter the atomizing chamber 14 for atomization. This design reduces humidification delay while ensuring water quality safety, thus meeting users' needs for immediate humidification. Furthermore, when the water temperature in the heating and condensing mechanism 22 reaches the preset temperature or when water is detected being discharged from the heating and condensing mechanism 22, the water flow in the filter mechanism 21 can be turned off, reduced, or maintained.

[0087] It should be noted that in step S100, when the humidifier is in humidification mode, the filter mechanism 21 and the heating and condensing mechanism 22 can be controlled to maintain water flow with the water storage chamber 13 and the atomizing chamber 14, so that the water in the water storage chamber 13 can enter the filter mechanism 21 and the heating and condensing mechanism 22 at the same time.

[0088] The filtration mechanism 21 filters the incoming water and discharges it into the atomizing chamber 14; while the heating and condensing mechanism 22 heats the incoming water and outputs condensate. Furthermore, there are various ways to control the water flow, such as controlling the opening of a solenoid valve or electric valve to connect the filtration mechanism 21 and the heating and condensing mechanism 22.

[0089] In step S200, the water in the filtration mechanism 21, after being filtered, can quickly enter the atomizing chamber 14. At this time, the atomizing device 30 can atomize the purified water and discharge the atomized water to achieve the purpose of rapid humidification.

[0090] In step S300, since heating in the heating and condensing mechanism 22 requires a relatively long time, the discharge of purified water from the heating and condensing mechanism 22 is relatively delayed. If the water temperature in the heating and condensing mechanism 22 is detected to have reached the preset temperature, or if the heating and condensing mechanism 22 outputs condensate, it means that the heating and condensing mechanism 22 has completed or is close to completing the water purification operation. Therefore, the working state of the filtration mechanism 21 can be controlled accordingly.

[0091] In controlling the working state of the filter mechanism 21, the filter mechanism 21 can continue to work, such as: keeping the water flow rate in the filter mechanism 21 constant, so that the filter mechanism 21 and the heating and condensing mechanism 22 synchronously provide clean water to the atomizing chamber 14; or the water flow rate of the filter mechanism 21 can be reduced, so that the heating and condensing mechanism 22 is the main humidification mechanism; or the water flow rate of the filter mechanism 21 can be turned off, that is, water is stopped from flowing into the filter mechanism 21, in which case the subsequent humidification is completed by the heating and condensing mechanism 22 alone.

[0092] It should be explained that the preset temperature refers to the temperature at which water boils and forms steam after being heated. It is related to the altitude. In some examples, the preset temperature can be, but is not limited to, 95℃~100℃.

[0093] Meanwhile, when selecting to turn off the water flow in the filter mechanism 21 in step S300, the filter mechanism 21 can be turned off immediately when the water temperature in the heating and condensing mechanism 22 is heated to the preset temperature or when the output of condensate water from the heating and condensing mechanism 22 is detected; or a delay program can be set to turn it off after a period of time, which can ensure that the mist output of the humidifier is more stable.

[0094] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0095] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
