For items with higher storage humidity requirements, the humidity inside the locker cannot be too low, otherwise it may affect the quality of the stored items.

[0003] Existing lockers usually have a humidification module installed inside the locker to ensure the humidity requirements inside the locker. A small water storage box is installed in the humidification module. The humidified air is distributed inside the locker through natural evaporation of the small water storage box or by means of fan-assisted blowing to achieve a suitable humidity environment. The water in the small water storage box will be consumed during the humidification process inside the locker, so it is necessary to replenish water in time when there is a shortage of water. In the prior art, there is already a solution of automatic water filling, which replenishes the small water storage box with water by setting a large water storage box to reduce the number of manual water filling times by users.

[0067] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] See also Figure 1 , is a first structural schematic diagram of a locker provided by an embodiment of the present invention. The embodiment of the present invention provides a locker 10, including a cabinet 11, wherein a storage compartment 12 is formed in the cabinet, and the storage compartment 12 is used to store items. The storage compartment 12 can be configured as a plurality of storage layers, a plurality of storage compartments, etc., or other formats according to user needs, which does not affect the beneficial effects of the present invention.

[0069] It should be noted that the storage cabinet 10 can be used in a variety of scenarios to store different types of items, such as a wine cabinet, a medicine cabinet, a merchandise cabinet or a refrigerator, thereby providing a storage environment with corresponding conditions for different types of items.

[0070] Typically, in order to ensure a suitable ambient temperature and humidity inside the storage compartment 12 , the locker 10 is further provided with a refrigeration device 13 and a humidification device 14 connected to the storage compartment 12 .

[0071] The refrigeration device 13 is used to provide cold capacity for the storage room 12 to reduce the compartment temperature of the storage room 12 and keep the storage room 12 at a low temperature. The refrigeration device 13 can be a compressor refrigeration, a semiconductor refrigeration or other refrigeration methods. The output cold capacity of the refrigeration device 13 can be adjusted according to actual needs. The adjustment of the output cold capacity is adjusted according to the system demand load, and is determined by comprehensively adjusting the ambient temperature, the compartment temperature and the humidity of the compartment, so as to control the temperature and humidity of the storage room to meet the requirements. Among them, when the compressor refrigeration method is adopted, the purpose of adjusting the output cold capacity can be achieved by adjusting the operating speed and / or operating frequency of the compressor. When semiconductor refrigeration is adopted, the purpose of adjusting the output cold capacity can be achieved by adjusting the input voltage. Of course, if other refrigeration methods are adopted, the output cold capacity can also be adjusted according to actual conditions, which will not be repeated here.

[0072] As an optional implementation, the refrigeration device 13 adopts a compressor refrigeration method, and the refrigeration device 13 includes components such as a compressor, a condenser, a drying filter, a capillary tube and an evaporator. The working structure of the refrigeration device 13 includes a compression process, a condensation process, a throttling process and an evaporation process. Among them, the compression process is: when the locker is powered on, when there is a refrigeration demand in the storage room, the compressor starts to work, and the low-temperature and low-pressure refrigerant is sucked into the compressor, and is compressed into a high-temperature and high-pressure superheated gas in the compressor cylinder and then discharged into the condenser; the condensation process is: the high-temperature and high-pressure refrigerant gas dissipates heat through the condenser, the temperature continues to drop, and is gradually cooled to a saturated vapor at room temperature and high pressure, and further cooled to a saturated liquid, and the temperature no longer drops. The temperature at this time is called the condensation temperature. The pressure of the refrigerant remains almost unchanged during the entire condensation process; the throttling process is: the condensed refrigerant saturated liquid is filtered out of water and impurities by the drying filter and flows into the capillary tube, through which it is throttled and depressurized, and the refrigerant becomes wet steam at room temperature and low pressure; the evaporation process is: it then begins to absorb heat and vaporize in the evaporator, which not only reduces the temperature of the evaporator and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor again, repeating the above process, transferring the heat in the storage room to the air outside the cabinet, achieving the purpose of refrigeration.

[0073] Of course, the specific form of the refrigeration device and its refrigeration method involved in the above scenario are only examples. In actual applications, they can be set according to actual conditions and are not specifically limited here.

[0074] See also Figure 2, is a schematic diagram of the first structure of the humidifying device in the embodiment of the present invention. The humidifying device 14 is used to provide moisture for the storage compartment 12, and plays a role in adjusting the compartment humidity of the storage compartment. It can start or stop running according to control requirements. Specifically, the humidifying device 14 includes a first water storage box 141 and a second water storage box 142; wherein, the first water storage box 141 is arranged in the cabinet 11, and is used to provide humidified water for the storage compartment 12. The second water storage box 142 is arranged in the cabinet 11, for example, it can be arranged at the bottom of the cabinet, and is connected to the first water storage box 141, and is used to replenish water for the first water storage box 141. Usually, the capacity of the second water storage box 142 is greater than the capacity of the first water storage box 141.

[0075] Optionally, in the humidifying device 14, the humidified air can be distributed in the cabinet by natural evaporation of the first water storage box or by fan-assisted blowing, or a plurality of humidifying jet holes can be provided on the inner wall of the storage compartment 12. When the humidifying device 14 is started, the water in the first water storage box is sprayed out from the jet holes to form a fine spray-like mist to achieve the humidification effect. Of course, other humidification methods can also be used or combined without affecting the beneficial effects achieved by the present invention.

[0076] Furthermore, the locker 10 also includes a controller 15, which is connected to the refrigeration device 13 and the humidification device 14 respectively to realize information collection, calculation and analysis, and issuance of control instructions, thereby controlling the operating parameters of the refrigeration device 13, the start-up or shutdown of the humidification device 14 and other working states.

[0077] Specifically, see Figure 3 , is a schematic diagram of the first working process of the controller in an embodiment of the present invention. The controller 15 is specifically used to execute steps S11 to S14:

[0078] S11, after the locker is powered on, controlling the second water storage box to perform a water filling action to replenish water for the first water storage box;

[0079] S12, after a first time period has passed, controlling the second water storage box to stop the water injection action; wherein the first time period is calculated based on the target water storage capacity of the first water storage box, the preset minimum water storage capacity and the preset water injection speed;

[0080] S13, calculating the water consumption of the first water storage box according to the time after the water injection is stopped and the water consumption rate of the first water storage box;

[0081] S14. When the water consumption is greater than or equal to the difference between the target water storage capacity and the minimum water storage capacity of the first water storage box, the second water storage box is controlled again to perform water filling.

[0082] In the embodiment of the present invention, after the locker 10 is powered on, the humidifier 14 also starts to operate in response to the corresponding control command. When the humidifier 14 starts to operate for the first time, water is first added to the second water storage box 142. The water injection method can be manual water injection by the user or water injection through an external water source. The amount of water injected into the second water storage box 142 generally does not exceed three quarters of the maximum capacity of the second water storage box 142. Then, after the second water storage box 142 is injected with water, the second water storage box 142 is controlled to perform the water injection action to replenish water for the first water storage box 141.

[0083] It should be noted that the target water storage capacity N1 of the first water storage box can be the maximum water storage capacity of the first water storage box 141, or any water storage capacity less than the maximum water storage capacity set according to user needs. min is the minimum amount of water that the first water storage box needs to maintain, N min ≥0.

[0084] The preset water injection speed is pre-set. Since the process of injecting water into the first water storage box 141 is achieved by extracting static water from the second water storage box, the water flow rate is stable, so the water injection speed is usually stable and can be calculated or tested through prior knowledge.

[0085] Furthermore, the time required for the water in the first water storage box 141 to reach the required target water storage volume N1, that is, the first time length t1, is calculated based on the preset water injection speed. In the process of controlling the second water storage box 142 to inject water into the first water storage box 141, the timing module built into the controller 15 performs timing. When the water injection time reaches the first time length t1, the second water storage box is controlled to stop the water injection action. Thereafter, the humidification device 14 works normally and consumes the water in the first water storage box 141 to provide moisture for the storage compartment 12. Furthermore, after the second water storage box stops the water injection action, the timing module built into the controller 15 performs timing, and records in real time the time elapsed after the water injection is stopped. Furthermore, in combination with the water consumption speed of the first water storage box 141 during the humidification process, the water consumption of the first water storage box 141 is calculated in real time. When the water consumption reaches △N, that is, the target water storage volume N1 and the minimum water storage volume N of the first water storage box, the water consumption of the first water storage box 141 is calculated in real time. min When the difference is , it indicates that the water in the first water storage box 141 is consumed, and the second water storage box is controlled again to perform the water injection action to replenish water for the first water storage box 141, and the cycle continues.

[0086] By adopting the technical means of the embodiment of the present invention, the locker is provided with a humidifying device, wherein a first water storage box of the humidifying device is arranged in the storage room for humidity adjustment, and a second water storage box is arranged to replenish water for the first water storage box, and the water filling operation of the first water storage box is realized according to parameters such as water filling speed and water consumption speed combined with time control to prevent the small water storage box from being short of water and overflowing. Compared with the prior art in which a plurality of liquid level sensors are arranged to monitor the water shortage state and the water full state in the water storage box, the embodiment of the present invention can ensure the normal operation of the humidifying device, effectively reduce the manufacturing cost of the humidifying device, and improve the user experience.

[0087] As a preferred implementation, the present invention is further implemented on the basis of the above-mentioned embodiments. Figure 4 , is a schematic diagram of a second working process of the controller in an embodiment of the present invention. After step S14, the controller is further configured to execute step S15:

[0088] S15. When the accumulated number of water injection actions is greater than or equal to a preset number threshold, the second water storage box is determined to be short of water; wherein the preset number threshold is calculated based on the ratio of the target water storage capacity of the second water storage box and the water injection capacity of a single water injection action.

[0089] It should be noted that the target water storage capacity N2 of the second water storage box can be the maximum water storage capacity of the second water storage box 142, or it can be any water storage capacity less than the maximum water storage capacity set according to user needs, such as three quarters of the maximum water storage capacity of the second water storage box.

[0090] In the embodiment of the present invention, the number of times that the second water storage box 142 can fill the first water storage box 141 with water is calculated based on the target water storage capacity N2 of the second water storage box 142 and the water injection amount of a single water injection action, as the preset number threshold. Specifically, the ratio N2 / △N of the target water storage capacity N2 of the second water storage box and the water injection amount of a single water injection action is calculated, and the preset number threshold m is obtained by rounding up. Wherein, △N=N1-N min , that is, the target water storage capacity N1 and the minimum water storage capacity N min The difference.

[0091] The embodiment of the present invention accumulates the number of times the second water storage box 142 performs the water injection action. As the number of times water is replenished to the first water storage box 141 increases, the water in the second water storage box 142 is consumed. When the accumulated number of water injection actions n satisfies n≥m, it indicates that the water in the second water storage box 142 is consumed, and it is determined that the second water storage box 142 is short of water.

[0092] By adopting the technical means of the embodiment of the present invention, the water injection action of the second water storage box is accumulated. When the accumulated number of executions of the water injection action reaches a certain threshold number, it is determined that the second water storage box is short of water, so that water can be replenished for the second water storage box in time to ensure the normal operation of the humidification device.

[0093] As a preferred embodiment, see Figure 5 , is a schematic diagram of the structure of the first water storage box in an embodiment of the present invention under a preferred embodiment, the first water storage box is composed of a shell 1411, a water storage part 1412, a humidification fan 1413, a humidification fiber 1414, a moisture guide block 1415, an air outlet 1416, an air inlet 1417 and a water injection port 1418, the water storage part 1411 is used to store water, the second water storage box 142 injects water into the water storage part 1411 of the first water storage box through the water injection port 1418, the moisture guide block 1415 is arranged in the water storage part 1411, the humidifying fiber 1414 is arranged above the humidifying block 1415, the water in the water storage part 1411 penetrates upward to the humidifying fiber 1414 through the humidifying block 1415, the humidifying fan 1413 is connected to the water storage part 1412 through the air inlet 1417, and the humidifying fan 1413 guides the humidified air in the humidifying fiber 1414 into the storage compartment 12 through the air outlet 1416.

[0094] Optionally, the accuracy problem caused by the water consumption calculation error can be offset by delaying water injection, that is, setting the water consumption L=N1+C as the next water injection interval of the small water box, wherein C is the preset water injection delay amount, which is set according to the time the humidification fiber can maintain wetness after the water box is dry and actual needs.

[0095] By adopting the technical means of the embodiment of the present invention, the humidifying fiber 1414 is installed above the moisture-conducting block 1415 and absorbs water from the water storage portion 1412 to keep itself moist, which greatly increases the evaporation area of ​​water, thereby being more conducive to regulating the humidity in the storage compartment 12. In addition, due to the characteristics of the humidifying fiber, even if the first water storage box is out of water, the humidifying fiber can still remain moist for a period of time to maintain the humidification performance, so to a certain extent, it can offset the control accuracy problem of water injection into the first water storage box caused by the water consumption calculation error.

[0096] In some embodiments, Figure 2As shown, at least a first storage compartment and a second storage compartment are formed in the cabinet 11, and the first storage compartment and the second storage compartment are separated by a first compartment partition, and the humidifying device 14 also includes a first humidifying fan and a second humidifying fan. The first water storage box 141 is built into the first compartment partition; the first water storage box is provided with a first air outlet toward the first storage compartment and a second air outlet toward the second storage compartment, respectively, and the first humidifying fan supplies air to the first water storage box when it is started, and guides the humidified air in the first water storage box to the first storage compartment through the first air outlet; the second humidifying fan supplies air to the first water storage box when it is started, and guides the humidified air in the first water storage box to the second storage compartment through the second air outlet.

[0097] Preferably, the first water storage box comprises a water storage box body and a water storage box cover, and the water storage box cover is detachably covered on the opening of the water storage box body. An isolation component is provided on a surface of the water storage box cover close to the water storage box body, and the vertical height of the isolation component is less than the depth of the water storage box body; the isolation component and the water in the water storage box body form an air isolation layer to divide the water storage box body into a first water storage part and a second water storage part that are connected;

[0098] The first water storage part is provided with a first air inlet and a first air outlet facing the first storage compartment, and the air outlet of the first humidifying fan is connected to the first air inlet; when the first humidifying fan is started and operated, air is supplied to the first water storage box 141, and the humidified air in the first water storage box 141 is guided to the first storage compartment through the first air outlet; the second water storage part is provided with a second air inlet and a second air outlet facing the second storage compartment, and the air outlet of the second humidifying fan is connected to the second air inlet; when the second humidifying fan is started and operated, air is supplied to the first water storage box 141, and the humidified air in the first water storage box 141 is guided to the second storage compartment through the second air outlet.

That is, the humidity of multiple storage compartments can be adjusted through one water storage box for humidification, thereby reducing the manufacturing cost of the humidification module and improving the user experience.

[0100] In addition, an insulating component is provided on the cover of the first water storage box, and there is a certain gap between the insulating component and the bottom of the body of the first water storage box, so that the water stored in the first water storage box can circulate. At the same time, the insulating component and the water form an air insulating layer, so that only water circulates but air does not circulate between the first water storage part and the second water storage part divided by the first water storage box, thereby preventing air convection between the first storage compartment and the second storage compartment, and avoiding the situation where the temperature and humidity of the first storage compartment and the second storage compartment are set at different levels, and the temperature and humidity interfere with each other due to air exchange.

[0101] Furthermore, a third storage compartment is provided in the cabinet, the third storage compartment is separated from the second storage compartment by a second compartment partition, and the third storage compartment is close to the bottom of the cabinet; the second water storage box 142 is located below the third storage compartment, the second water storage box is provided with a third air outlet facing the third storage compartment, and the humidified air in the second water storage box is guided to the third storage compartment through the third air outlet.

[0102] By adopting the technical means of this embodiment, the second water storage box 142 is used to replenish water for the first water storage box 141, and is also reused to provide moisture for the third storage compartment, and the humidity in the third storage compartment is adjusted by replenishing humidity to the third storage compartment through the third air outlet through natural evaporation of a large area of ​​liquid surface. By reusing the second water storage box, there is no need to set up an additional small water storage box with the same function as the first water storage box in the third storage compartment for humidification, which further simplifies the structure of the humidification device and reduces the manufacturing cost of the humidification device.

[0103] On this basis, see Figure 6 , is a third working flow diagram of the controller in an embodiment of the present invention, then step S13, that is, calculating the water consumption of the first water storage box according to the time after the water injection is stopped and the water consumption rate of the first water storage box, specifically includes steps S131 to S133:

[0104] S131, determining the startup operation time of the humidification fan during the time after the water injection is stopped, and the water consumption rate of the first water storage box when the humidification fan is started, recorded as a first water consumption rate;

[0105] S132, calculating a first water consumption according to the startup operation time and the first water consumption rate;

[0106] S133, determining the stopping time of the humidification fan during the time after the water injection is stopped, and the water consumption rate of the first water storage box when the humidification fan stops running, recorded as a second water consumption rate;

[0107] S134, calculating a second water consumption according to the stop operation time and the second water consumption rate;

[0108] S135. Calculate the sum of the first water consumption and the second water consumption to obtain the water consumption of the first water storage box.

[0109] In the embodiment of the present invention, the water consumption rate of the first water storage box 141 when the humidifying fan 1413 is started and operated is calculated or tested in advance according to prior knowledge, as the first water consumption rate v on , and calculate the water consumption rate of the first water storage box 141 when the humidification fan 1413 stops running as the second water consumption rate v off Then, after the first water storage box 141 is filled with water, the startup running time t of the humidification fan 1413 is obtained in real time. on , and the total time after stopping water injection minus the startup operation time t on , the stopping time t of the humidification fan 1413 can be calculated off , according to the startup running time t on and the first moisture consumption rate v on , calculate the first water consumption L on =v on ×t on , according to the stop operation time t off and the second moisture consumption rate v off , calculate the second water consumption L off =v off ×t off , the water consumption of the first water storage box during humidification is calculated as L = L on +L off Furthermore, when the water consumption L≥N1, it indicates that the water in the first water storage box 141 has been consumed, and the second water storage box 142 is controlled to perform a water injection operation.

[0110] By adopting the technical means of the embodiment of the present invention, the structure of the first water storage box and the water injection control process of the humidifier are optimized, and a second water storage box is set as a container for storing external water or manual water addition by the user. The water in the second water storage box is extracted into the first water storage box through time control, and then the auxiliary humidification components such as humidification fiber and humidification fan are used to consume the water in the first water storage box to adjust the humidity of the storage compartment. At the same time, the running time of the humidification fan in the first water storage box and the time after the water injection of the first water storage box are recorded, and the water consumption rate of the first water storage box when the humidification fan is running and the water consumption rate when the humidification fan is not running are tested through data to calculate the real-time water consumption, so that when the water consumption reaches the target water storage capacity of the first water storage box, the second water storage box is started to control the water to replenish the first water storage box, so as to effectively realize the monitoring of the water shortage state and the full water state of the first water storage box, ensure the normal operation of the humidifier, effectively reduce the manufacturing cost of the humidifier, and improve the user experience.

[0111] As a preferred embodiment, the embodiment of the present invention optimizes the calculation method of the second water consumption of the first water storage box when the humidification fan stops running. Among them, when the humidification fan stops running, the second water consumption rate of the first water storage box is mainly related to the current ambient temperature and ambient humidity.

[0112] Specifically, the calculating the second water consumption according to the stop operation time and the second water consumption rate includes:

[0113] Real-time detection of current ambient temperature and humidity;

[0114] According to the ambient temperature and the ambient humidity, the duration of the stop operation is divided into at least one evaporation time period; wherein the values ​​of the ambient temperature and the ambient humidity in each evaporation time period are stably within a corresponding preset range;

[0115] Determine the water evaporation rate of the first water storage box in each evaporation time period according to the ambient temperature and ambient humidity in each evaporation time period; wherein the second water consumption rate is composed of the water evaporation rate in each evaporation time period;

[0116] The second water consumption is calculated according to the duration of each evaporation time period and the water evaporation rate.

[0117] In the embodiment of the present invention, the controller detects the ambient temperature T and ambient humidity D of the location of the locker in real time. The ambient temperature T and ambient humidity D may be detected by setting corresponding environmental sensors on the locker, or the ambient temperature and ambient humidity of the area where the locker is located may be obtained by the controller from the cloud through a network interface, which is not specifically limited here.

[0118] During the stop operation time t off According to the changes of the ambient temperature T and the ambient humidity D, the time period is divided into several evaporation time periods, wherein the ambient temperature T and the ambient humidity D in each evaporation time period are within a certain stable range. As an example, for the ambient temperature, the temperature (T1, T2) is divided into a preset interval, and the temperature (T2, T3) is divided into a preset interval. When the operation is stopped for a period of time t off The time corresponding to the ambient temperature being continuously in the temperature range (T1, T2) is determined as an evaporation time period, and the time corresponding to the ambient temperature being continuously in the temperature range (T2, T3) is determined as an evaporation time period, thereby at least one evaporation time period can be obtained.

[0119] It can be understood that if the corresponding interval of the current ambient temperature T or ambient humidity D changes, a new evaporation time period will be constructed.

[0120] The influence of the ambient temperature T and the ambient humidity D on the water evaporation rate of the first water storage box is simplified in advance into mutually independent linear functions, specifically:

[0121] v T =T*M;

[0122] v D =D*N;

[0123] Among them, v T is the evaporation rate of water under the influence of ambient temperature, v D is the water evaporation rate under the influence of ambient humidity, M and N are the preset influence coefficients corresponding to ambient temperature and ambient humidity, respectively, which are constants.

[0124] Furthermore, according to the ambient temperature and ambient humidity in each evaporation time period, the evaporation rate of the water in the first water storage box in each evaporation time period can be determined.

[0125] The second water consumption is calculated according to the duration of each evaporation time period and the water evaporation rate:

[0126]

[0127] Where N is the number of divided evaporation time periods, is the duration of the i-th evaporation time period;

[0128] It should be noted that, during the startup of the humidification fan, the water consumption of the first water storage box is greatly affected by the humidification fan, and the influence of the ambient temperature and humidity on the water consumption is very small and can be ignored.

[0129] The following is a specific example to explain the calculation process of the water consumption of the first water storage box:

[0130] Assuming that the current ambient temperature is T1 and the ambient humidity is D1, the startup running time of the humidification fan in the evaporation time period t1 is t on，1 , the stop time is t off，1 , then the water consumption of the first water storage box during time t1 is:

[0131] L1=v on ×t on，1 +(v T，1 +v D，1 )×t off，1 ;

[0132] Similarly, in the next evaporation time period t2 when the current ambient temperature and humidity change to T2 and D2, the startup running time of the humidification fan is t on，2 , the stop time is t off，2 , then the water consumption of the first water storage box during time t2 is:

[0133] L2=v on ×t on，2 +(v T，2 +v D，2 )×t off，2 ;

[0134] The water consumption corresponding to N evaporation time periods is calculated by analogy. After the water filling is completed, the water consumption of the first water storage box is:

[0135] L=L1+L2+……+L N

[0136] = {v on ×t on，1 +(v T，1 +v D，1 )×t off，1}+{v on ×t on，2 +(v T，2 +v D，2 )×t off，2}+…+{v on ×t on，N +(v T，N +v D，N )×t off，N}.

[0137] By adopting the technical means of the embodiment of the present invention, when the humidification fan stops running, the water consumption of the first water storage box is determined according to the ambient temperature and ambient humidity, thereby effectively monitoring the water shortage state and the full water state of the first water storage box, ensuring the normal operation of the humidification device and improving the user experience.

[0138] As a preferred implementation, the present invention is further implemented on the basis of the above-mentioned embodiments. Figure 7 , is a second structural diagram of a humidifying device in an embodiment of the present invention, wherein the humidifying device 14 further comprises a water injection pipe 143 and a water injection pump 144, and the second water storage box 142 is connected to the first water storage box 141 via the water injection pipe 143 and the water injection pump 144. Figure 7 As shown, one end of the water injection pipe 143 is inserted into the water injection port of the first water storage box 141, and the other end is inserted into the water outlet of the second water storage box 142, and the water injection pump 144 is arranged on the water injection pipe 143. Under the control of the controller 15, the water injection pump 144 is turned on at regular intervals to extract water from the second water storage box 142 and inject it into the first water storage box 141.

[0139] Then in steps S11 and S14, the controlling the second water storage box to perform the water filling action is specifically: controlling the water filling pump to start, so as to pump water from the second water storage box to the first water storage box through the water filling pipe.

[0140] The opening time of the water injection pump is the first time, which is calculated according to the target water storage capacity of the first water storage box, the preset minimum water storage capacity and the preset water injection speed by the following calculation formula:

[0141]

[0142] Wherein, t1 is the first time length, N1 is the target water storage capacity of the first water storage box, N min is the preset minimum water storage capacity, u is the preset water injection speed, which is the same as the pumping speed of the water injection pump, k is the preset safety factor, 0<k<(N max –N1) / u,N max The preset maximum water storage capacity.

[0143] It should be noted that k is a preset safety factor value used to eliminate individual errors of the water injection pump.

[0144] As a preferred implementation, the embodiment of the present invention is further implemented on the basis of any of the above embodiments, and the embodiment of the present invention optimizes the way of injecting water when the second water storage box is short of water.

[0145] In the first alternative embodiment, see Figure 8, is a third structural schematic diagram of a humidifying device in an embodiment of the present invention, wherein the humidifying device 14 further comprises an external water pipe 145 and a water valve 146, and the second water storage box 142 is connected to an external water source via the external water pipe 145 and the water valve 146. One end of the external water pipe 145 is inserted into the water injection port of the second water storage box 142, and the other end is connected to an external water source, such as a reservoir, a pool, etc. The water valve 146 is arranged on the external water pipe 145, and the water valve 146 is used to control the start and stop of the water injection process of the second water storage box 142. The water valve 146 is started or stopped under the control of the controller 15, and water in the external water source is extracted and injected into the second water storage box 142 when it is started.

[0146] See Fig. 9 , is a fourth working flow diagram of the controller in an embodiment of the present invention. In step S15, after determining that the second water storage box is short of water, the controller is further configured to execute step S16:

[0147] S16, controlling the water valve to open so as to pump water from the external water source to the second water storage box through the external water pipe.

[0148] Preferably, the humidifying device further comprises a flow meter, which is arranged on the external water pipe and is used to monitor the real-time water injection flow of the external water pipe.

[0149] Then in step S16, that is, after controlling the water valve to open so as to pump water from the external water source to the second water storage box through the external water pipe, the controller is further configured to execute steps S17 and S18:

[0150] S17, judging whether the current water storage capacity of the second water storage box reaches the target water storage capacity of the second water storage box according to the real-time water injection flow rate and the accumulated opening time of the water valve;

[0151] S18: If yes, control the water valve to close to stop pumping water to the second water storage box.

[0152] In the embodiment of the present invention, water is replenished in the second water storage box by using an external water source. Since the external water source may be affected by regional water pressure differences and the water flow rate is unstable, a flow meter is set to monitor the water injection flow in real time, and the current water volume injected into the second water storage box 142 is calculated based on the real-time water injection flow and the accumulated opening time of the water valve, and then the water injection is stopped when the current water storage volume reaches the target water storage volume N2.

[0153] In the second alternative embodiment, see Fig.10 , is a second structural diagram of a locker provided in an embodiment of the present invention, wherein the locker further comprises a reminder device 16, and the reminder device 16 is used to execute a preset reminder action.

[0155] S16', controlling the reminding device to execute a preset reminding action; wherein the reminding action is used to remind the user to refill the second water storage box with water.

[0156] In the embodiment of the present invention, the user manually adds water to replenish the second water storage box. When it is determined that the second water storage box 142 is short of water, the controller 15 controls the reminder device 17 to start running and execute the corresponding reminder action. After receiving the reminder content, the user manually adds water to the second water storage box through the water filling port 1421 on the second water storage box.

Of course, the reminder device 17 can also be any two of the above forms or a combination of two forms, or it can be other reminder forms, all of which do not affect the beneficial effects achieved by the present invention.

[0158] It should be noted that the humidifying device 14 can also replenish water for the second water storage box in two ways: an external water source and manual water addition by the user, which does not affect the beneficial effects achieved by the present invention.
