Technical Field

[0002] Currently, most household water purifiers only provide clean water, and a separate humidifier is needed to increase the humidity in the air. Even if a small number of household water purifiers have a humidification function, the water source for humidification and the purified water source are stored in the same location. This results in a technical problem where existing water purifiers with humidification functions simultaneously supply purified water while performing humidification, leading to insufficient water supply for humidification and consequently, lower humidification efficiency.

[0026] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0028] It should be noted that the following diagram shows one possible implementation method, and it is not actually required to strictly follow this implementation method.

[0029] Figure 1 This is a schematic diagram of a water purifier with humidification function according to an embodiment of this application. Figure 1 .like Figure 1 As shown, the water purifier may include a water purification device, which includes a water purification unit, a first pure water storage unit, and a water outlet unit. The water purification unit is used to purify raw water into pure water without dissolved substances. The pure water is guided to the first pure water storage unit for storage, and then supplied to the water purifier through the water outlet unit. The water purifier is characterized in that it also includes a humidification device, which includes a flow limiting valve unit, a second pure water storage unit, an ultrasonic generator, and a mist outlet unit.

[0030] The flow limiting valve unit is used to guide the pure water in the first pure water storage unit from the first pure water storage unit to the second pure water storage unit;

[0031] An ultrasonic generator is used to atomize the pure water in the second pure water storage unit into water mist;

[0032] The mist outlet unit is used to guide the water mist in the second pure water storage unit to spray out of the water purifier.

[0033] In the embodiments of this specification, the water purification unit can be connected to the first pure water storage unit, the first pure water storage unit can be connected to the water outlet unit, the first storage unit can be connected to the flow limiting valve unit, the flow limiting valve unit can be connected to the second pure water storage unit, the second pure water storage unit can be connected to the mist outlet, and the second pure water storage unit can be connected to the ultrasonic generator.

[0034] The water purification unit may include a raw water storage tank, a raw water filter cartridge, a wastewater valve, and a sterilization device. The raw water storage tank stores raw water that has not yet been filtered by the water purifier. The raw water filter cartridge purifies the raw water in the storage tank into pure water free of dissolved substances. The wastewater valve controls the flow of wastewater after the raw water has been filtered by the filter cartridge. The sterilization device eliminates a predetermined proportion of microorganisms in the water filtered by the filter cartridge. This predetermined proportion may be related to the functional parameters of the sterilization device, which may be an ultraviolet sterilization device. A reverse osmosis (RO) pump may be installed between the raw water storage tank and the raw water filter cartridge, and the raw water filter cartridge may also be a filter cartridge with an added RO membrane.

[0035] The flow-limiting valve unit can guide pure water from the first pure water storage unit to the second pure water storage unit at a preset flow rate. The preset flow rate can be set by the user of the water purifier or pre-set by the manufacturer in the control system of the water purifier.

[0036] The number of raw water storage tanks, raw water filter cartridges, wastewater valves, first pure water storage units, outlet units, flow limiting valve units, second pure water storage units, ultrasonic generators, and mist outlet units is not limited. For example, there are two first pure water storage units for storing pure water purified by the water purification unit, and two flow limiting valves guide the pure water from the two first pure water storage units to the two second pure water storage units at different preset flow rates. Each second pure water storage unit is connected to two ultrasonic generators.

[0037] A flow-limiting valve unit guides purified water from the first purified water storage unit to the second purified water storage unit. An ultrasonic generator atomizes the purified water in the second purified water storage unit into water mist. A mist outlet unit guides the water mist from the second purified water storage unit out of the water purifier. This achieves the technical effect of pre-diverting a portion of the purified water from the storage tank for use during humidification. This solves the technical problem in existing water purifiers with humidification functions that, while humidifying, simultaneously supply purified water, resulting in insufficient water supply and thus low humidification efficiency.

[0038] Figure 2 This is a schematic diagram of a water purification device according to an embodiment of this application. Figure 2 As shown, the water purification device may also include a first pure water export unit;

[0039] The first pure water export unit is used to obtain the water level drop of the pure water in the first pure water storage unit every second preset time period, and discharge the pure water in the first pure water storage unit to the outside of the second pure water storage unit when the water level drop is positive and not greater than the preset water level drop.

[0040] In the embodiments described in this specification, the second preset time period and the preset water level drop can be set by the user of the water purifier or preset by the manufacturer in the control system of the water purifier. The water level drop is the value obtained by subtracting the water level at the initial time point from the water level at the last time point in the second preset time period. The first pure water export unit can be connected to the first pure water storage unit, and the number of first pure water export units is not limited.

[0041] For example, the second preset time period is 8 minutes, and the preset water level drop is 10 ml. The first pure water export unit is used to obtain the water level drop of the pure water in the first pure water storage unit every 8 minutes. If the water level drop is not greater than 10 ml, the pure water in the first pure water storage unit is discharged from the first pure water storage unit to the outside of the second pure water storage unit. For example, it is discharged into the raw water storage tank in the water purification unit, or discharged to the outside of the water purifier through the wastewater valve in the water purification unit, or the user is reminded to collect water through the outlet unit to discharge it to the outside of the water purifier.

[0042] This technology prevents the purified water from growing bacteria during storage when the water purifier is not discharging purified water for a certain period, thus preventing the use of bacteria-laden water for humidification. This solves the problem in existing technologies where, although the water used for humidification in a water purifier with a humidification function is purified water, the purified water has been stored for a long time and has grown bacteria, resulting in the atomized water mist carrying a large number of bacteria.

[0043] Figure 3 This is a schematic diagram of a humidification device according to an embodiment of this application. Figure 1 .like Figure 3 As shown, the humidification device may also include a second pure water export unit;

[0044] The second pure water export unit is used to supply pure water from the first pure water storage unit to the outside of the water purifier through the outlet unit and to obtain the water level of the pure water in the first pure water storage unit when the ultrasonic generator is not started. When the water level is less than the first preset water level threshold, the unit controls the pure water in the second pure water storage unit to be guided to the first pure water storage unit through the flow limiting valve unit.

[0045] In the embodiments described in this specification, the second pure water outlet unit can be connected to the flow limiting valve unit, the second pure water storage unit, and the first pure water storage unit, and the number of second pure water outlet units is not limited. The first preset water level threshold can be set by the user of the water purifier or preset by the manufacturer in the control system of the water purifier.

[0046] For example, the first preset water level threshold can be 30ml pre-set by the manufacturer. The second pure water export unit provides pure water from the first pure water storage unit to the outside of the water purifier through the outlet unit. When the ultrasonic generator is not started, the unit obtains the water level of the pure water in the first pure water storage unit. When the water level is less than 30ml, the unit controls the pure water in the second pure water storage unit to be guided to the first pure water storage unit through the flow limiting valve unit.

[0047] This solves the technical problem in the existing technology where the water purifier is inefficient in supplying purified water because the water source is only a single water tank for storing purified water.

[0048] In one optional embodiment, the humidifying device further includes a humidifying control unit; the humidifying control unit is capable of receiving a first humidifying command instructing the humidifying device to perform humidifying operation;

[0049] The humidification control unit is used to obtain the water level of the pure water in the first pure water storage unit when it receives the first humidification command, and control the ultrasonic generator to start when the water level is greater than the first preset water level threshold, so that the pure water in the second pure water storage unit is atomized into water mist, and then sprayed out of the water purifier based on the mist outlet unit.

[0050] For example, the first preset water level threshold is 30ml. When the humidification control unit receives the first humidification command, it obtains the water level of the pure water in the first pure water storage unit as 35ml. When the water level of 35ml is greater than the first preset water level threshold of 30ml, it controls the ultrasonic generator to start so that the pure water in the second pure water storage unit is atomized into water mist, and then sprays the water mist out of the water purifier based on the mist outlet unit.

[0051] This achieves the technical effect of maintaining a continuous and uninterrupted flow of water mist produced by the water purifier when using its humidification function. This solves the technical problem in existing water purifiers with built-in humidification functions where insufficient water supply, even when water production is activated, can lead to discontinuous water mist during humidification due to untimely or insufficient water production to meet humidification consumption, thus affecting user experience and resulting in low humidification efficiency.

[0052] In one optional embodiment, the humidification device further includes a hygrometer unit and a humidification control unit; the humidification control unit is capable of receiving a first humidification command instructing the humidification device to perform humidification operation;

[0053] The hygrometer unit is used to detect the ambient humidity within a preset range outside the water purifier;

[0054] The humidification control unit is used to obtain the water level of the pure water in the first pure water storage unit and the ambient humidity when it receives the first humidification command. When the water level is greater than the first preset water level threshold and the ambient humidity is less than the preset humidity threshold, it controls the ultrasonic generator to start so that the pure water in the second pure water storage unit is atomized into water mist, and then sprays the water mist out of the water purifier based on the mist outlet unit.

[0055] In the embodiments described in this specification, the hygrometer unit can be a device used to detect the ambient humidity within a preset range outside the water purifier. The model, parameters, number, etc., of the hygrometer unit are not limited here. The preset range can be the detectable range of the hygrometer unit, set by the user of the water purifier or pre-set by the manufacturer in the control system of the water purifier. The preset humidity threshold can also be set by the user of the water purifier or pre-set by the manufacturer in the control system of the water purifier.

[0056] For example, the detection range of the hygrometer unit is 23m. 3 The preset range is 15m, which is set by the user. 3 The preset humidity threshold is 40% set by the user. When the humidification control unit receives the first humidification command, it obtains the water level of 35ml in the first pure water storage unit and the ambient humidity of 33%. When the water level of 35ml is greater than the first preset water level threshold of 30ml and the ambient humidity of 33% is less than the preset humidity threshold of 40%, it controls the ultrasonic generator to start so that the pure water in the second pure water storage unit is atomized into water mist, and then the water mist is sprayed out of the water purifier based on the mist outlet unit.

[0057] This achieves the technical effect of preventing water waste by causing the humidification function of the water purifier to fail to activate when the ambient humidity is high. This solves the technical problem of water waste caused by existing water purifiers with built-in humidification functions when the ambient humidity is suitable, even if the humidification function is successfully activated remotely.

[0058] Figure 4 This is a schematic diagram of a humidification device according to an embodiment of this application. Figure 2 .like Figure 4 As shown, the humidification device may also include an active humidification control unit;

[0059] The active humidification control unit is used to control the ultrasonic generator to start when the water level of the pure water in the first pure water storage unit is not lower than the second preset water level threshold every first preset time period, so that the pure water in the second pure water storage unit is atomized into water mist, and then the water mist is sprayed out of the water purifier through the mist outlet unit until the water level is lower than the second preset water level threshold.

[0060] In the embodiments described in this specification, the first preset time period and the second preset water level threshold can be set by the user of the water purifier or preset by the manufacturer in the control system of the water purifier. The second preset water level threshold is greater than the first preset water level threshold. The active humidification control unit can be connected to the ultrasonic generator and the first pure water storage unit.

[0061] For example, the first preset time period is 30 minutes and the second preset water level threshold is 100 ml. When the water level of the pure water in the first pure water storage unit is not less than the second preset water level threshold of 100 ml every 30 minutes, the active humidification control unit controls the ultrasonic generator to start so that the pure water in the second pure water storage unit is atomized into water mist, and then sprays the water mist out of the water purifier based on the mist outlet unit until the water level is less than the second preset water level threshold of 100 ml.

[0062] This achieves the technical effect of preventing the purified water level in the tank from becoming too high through the humidification function, thereby improving the circuit safety of the components in the water purifier. This solves the technical problem in existing water purifiers with humidification functions where the water level remains too high for a certain period, causing the purified water to overflow the tank and potentially submerge the components, resulting in lower circuit safety.

[0063] In one optional embodiment, the humidification device further includes a first temperature sensor unit, a second temperature sensor unit, a heating unit, and a heating and humidification control unit; the heating and humidification control unit is capable of receiving a second humidification command that instructs the humidification device to perform humidification operation at a preset temperature;

[0064] The heating unit is used to heat the purified water from the water purification unit before it enters the first pure water storage unit for storage.

[0065] The first temperature sensor unit is used to detect the first temperature of the purified water from the water purification unit before it is heated by the heating unit.

[0066] The second temperature sensor unit is used to detect the second temperature of the purified water from the water purification unit after it has been heated by the heating unit.

[0067] The heating and humidification control unit, upon receiving a second humidification command, determines the matching heating power of the heating unit based on the first temperature and the preset temperature. Then, based on the matching heating power, it heats the purified water from the water purification unit, adjusting the second temperature to the third temperature. The purified water heated to the third temperature is then directed to the first pure water storage unit for storage. The pure water in the first pure water storage unit is then directed to the second pure water storage unit via a flow-limiting valve unit. Finally, the supergas generator is activated to atomize the pure water in the second pure water storage unit into water mist, which is then sprayed out of the water purifier via the mist outlet unit. The third temperature differs from the preset temperature within a preset error temperature range.

[0068] In the embodiments described in this specification, the number of the first temperature sensor unit, the second temperature sensor unit, and the heating unit is not limited. The heating unit can be a device that heats the purified water from the water purification unit before it enters the first pure water storage unit; the model and power of the heating unit are not limited here. The first temperature sensor unit can be a device that detects the first temperature of the purified water before it is heated by the heating unit; the model and parameters of the first temperature sensor unit are not limited here. The second temperature sensor unit can be a device that detects the second temperature of the purified water after it has been heated by the heating unit; the model and parameters of the second temperature sensor unit are not limited here. The preset temperature and the error temperature range can be set by the user of the water purifier or preset by the manufacturer in the control system of the water purifier. The difference between the third temperature and the preset temperature can be the preset temperature minus the third temperature.

[0069] For example, the first temperature is 23℃, the second temperature can be 22.5℃, the preset temperature is 56℃, and the error temperature range is within ±2℃. Upon receiving a second humidification command, the heating and humidification control unit determines the matching heating power of the heating unit based on the first temperature 23℃ and the preset temperature 56℃. Then, based on the matching heating power, it heats the purified water from the water purification unit, adjusting the second temperature from 22.5℃ to a third temperature of 55.5℃. The purified water heated to the third temperature of 55.5℃ is then guided to the first pure water storage unit for storage. The pure water in the first pure water storage unit is then guided to the second pure water storage unit via a flow-limiting valve unit. The supergas generator is then activated to atomize the pure water in the second pure water storage unit into water mist, which is then sprayed out of the water purifier via the mist outlet unit. The difference between the third temperature of 55.5℃ and the preset temperature of 56℃ is ±0.5℃, which is within the preset error temperature range of ±2℃.

[0070] This technology ensures that the atomized water mist in the water purifier is at a temperature close to the preset temperature during humidification, thereby improving the humidification experience. This solves the problem of existing water purifiers with humidification functions failing to adjust the temperature of the water mist, resulting in a poor humidification experience.

[0071] In one alternative embodiment, the humidification device further includes a blower unit;

[0072] The blowing unit is used to blow air into the second pure water storage unit.

[0073] In the embodiments of this specification, the blowing unit can be a device that blows air into the second pure water storage unit. The number, model, equipment parameters, etc. of the blowing units are not limited here.

[0074] For example, the blowing unit can be a blower with a power of 0.75 kilowatts.

[0075] This achieves the technical effect of increasing the speed at which water mist diffuses outside the water purifier. This solves the technical problem in existing water purifiers with humidification functions where the slow diffusion of water mist outside the purifier, relying solely on the normal diffusion rate, results in low humidification efficiency.

[0076] Figure 5 This is a schematic diagram of a water purifier with humidification function according to an embodiment of this application. Figure 2 .like Figure 5 As shown, the water purifier may also include a dissolved substance detection device; the dissolved substance detection device includes a first dissolved substance detection unit, a second dissolved substance detection unit, and a dissolved substance parameter display unit;

[0077] The first dissolved substance detection unit is used to detect the concentration of dissolved substances in the raw water.

[0078] The second dissolved substance detection unit is used to detect the concentration of dissolved substances in the purified water after the raw water has been purified.

[0079] The dissolved substance parameter display unit is used to display the solubility of dissolved substances in raw water and the concentration of dissolved substances in pure water.

[0080] In the embodiments of this specification, the concentration of dissolved substances in the raw water can be the total dissolved solids (TDS) concentration of the raw water, and the concentration of dissolved substances in the purified water can be the TDS concentration of the raw water after purification. The first dissolved substance detection unit can be a device used to detect the concentration of dissolved substances in the raw water; the model, functional parameters, etc., of the first dissolved substance detection unit are not limited here. Similarly, the model, functional parameters, etc., of the second dissolved substance detection unit and the dissolved substance parameter display unit are not limited. The first and second dissolved substance detection units can be connected to the water purification unit.

[0081] For example, the dissolved substance parameter display unit can also be connected to the terminal of a user using a water purifier to send the concentration of dissolved substances in the raw water and the concentration of dissolved substances in the purified water to the terminal to improve the user experience.

[0082] This allows the water purifier's display device to show the concentration of dissolved substances in the water before and after purification, thus increasing the richness of the displayed parameters. This solves the technical problem in existing water purifiers with humidification functions where the displayed parameters for each function are limited, resulting in a low richness of displayed parameters.

[0083] In one alternative implementation, the structure of the mist outlet unit becomes narrower towards the outside of the water purifier.

[0084] In the embodiments described in this specification, the mist outlet unit is a device used to guide the water mist in the second pure water storage unit to spray out of the water purifier. The part of the mist outlet unit becomes narrower and narrower as it approaches the outside of the water purifier. The specific structure of the mist outlet unit is not limited here.

[0085] This allows the water purifier to increase the coverage of its water mist when using the humidification function. This solves the technical problem in existing water purifiers with built-in humidification functions where the upper and lower cross-sectional areas of the device transmitting water mist are equal, resulting in a lower speed at which the water mist is transmitted outwards, thus limiting its ability to travel greater distances.

[0086] In one optional embodiment, the humidification device further includes a first alarm unit for the amount of pure water;

[0087] The first alarm unit for pure water volume is used to obtain the water level during the start-up of the ultrasonic generator. If the water level is not greater than the first preset water level threshold, an alarm is sent to the water purification device to start the water purification process.

[0088] For example, the first alarm unit for pure water volume obtains the water level during the start-up of the ultrasonic generator. The water level is 15ml. When the water level of 15ml is not greater than the first preset water level threshold of 30ml, the unit alarms the water purification device so that the water purification device controls the water purification unit to start the water purification process after receiving the alarm.

[0089] This achieves the technical effect of supplementing the water source used for humidification during the humidification process of the water purifier.

[0090] This solves the technical problem of insufficient water supply during humidification in existing water purifiers with humidification functions, where the water source is only a water tank containing purified water that has been stored for a long time, and the amount of water in the tank may not be sufficient to guarantee the humidification supply.

[0091] In one optional embodiment, the humidification device further includes a second alarm unit for the pure water volume;

[0092] The second alarm unit for pure water volume is used to acquire the water level and the water purification start-up status of the water purification device during the start-up of the ultrasonic generator. When the water purification start-up status indicates that the water purification device is in the process of starting water purification or that the water level is greater than the second preset water level threshold, the alarm unit will be sent to the water purification device to shut down the water purification process.

[0093] For example, the second alarm unit for pure water volume obtains the water level of 103ml and the water purification device's purification start status as activated during the start-up of the ultrasonic generator. Since the water purification start status is activated and the water level of 103ml is greater than the second preset water level threshold of 100ml, it alarms the water purification device so that the water purification device controls the water purification unit to shut down the water purification process after receiving the alarm.

[0094] This technology prevents the humidification water source from overflowing due to re-purification during the humidification process, thus improving the circuit safety of the water purifier's components. It also solves the problem in existing water purifiers with humidification functions where the water level remains excessively high for a period of time during humidification, causing purified water to overflow the tank and potentially submerge the components, resulting in lower circuit safety.
