Description

Technical Field

[0001] This invention relates to the field of air purification device technology, and in particular to a water supply system and an air purification device. Background Technology

[0002] Currently, air purifiers sterilize by electrolyzing salt water to produce hypochlorous acid, which is then humidified to release chloride ions into the air. In the entire humidification system, the water tank is designed on the lower side of the unit. An electrolysis module is installed in the water tank to electrolyze the salt water into hypochlorous acid. The water is then pumped into the upper water tank for shower-style humidification.

[0003] However, to ensure the concentration of hypochlorous acid in the air, the salt water concentration must remain consistent throughout use. Therefore, the current method involves adding salt to the water tank to maintain a constant initial concentration. This results in the entire water tank being filled with salt water. If the user switches from disinfection mode to humidification mode (i.e., only wanting humidification), the humidified water will be salt water. Prolonged humidification can lead to excessive salt levels in the air, causing discomfort and negatively impacting the home environment in the long run. Furthermore, the current design requires users to change the water themselves, leading to a decreased user experience. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a water supply system for an air purification device, wherein the water supply system separately holds a chloride-containing salt solution and clean water in the working chamber as needed, separating the processes of supplying clean water and supplying disinfectant water, avoiding the use of the chloride-containing salt solution when supplying clean water, and greatly improving the user's comfort during the air humidification stage.

[0005] The present invention also proposes an air purification device for a water supply system that utilizes the above-mentioned air purification device.

[0006] According to an embodiment of the present invention, a water supply system for an air purification device has operating modes, including a clean water supply mode and a disinfectant supply mode. The water supply system includes: a main body, which defines a working chamber and a first liquid storage chamber. The working chamber has a water supply port and a wastewater port. The first liquid storage chamber, used for storing clean water, has a first water outlet communicating with the working chamber. The main body also has a salt inlet; a switching assembly, which controls the switching of the water supply port, the wastewater port, and the first water outlet; an electrolysis module, disposed on the main body, which electrolyzes a chloride-containing salt solution in the working chamber to produce disinfectant containing hypochlorous acid; and a control module, which is electrically connected to the switching assembly and the electrolysis module to control the switching of the water supply system between different operating modes.

[0007] According to an embodiment of the present invention, the water supply system of the air purification device defines a working chamber and a first liquid storage chamber. The working chamber is provided with a water supply port, a wastewater port and a salt addition port. By controlling the opening and closing of the wastewater port, the working chamber can be separately filled with a chloride-containing salt solution and clean water as needed, thus separating the process of supplying clean water and supplying disinfectant water. This avoids the water supplied by the air purifier in the humidification mode being a chloride-containing salt solution, thereby improving the user's comfort during the air humidification stage.

[0008] In some embodiments, each of the operating modes has an activation phase, and the control module includes: a first acquisition unit, which is used to acquire the feedback voltage of the electrolysis module; a second acquisition unit, which is used to acquire the operating mode to which the activation phase belongs; a comparison unit, which is used to compare the feedback voltage with a preset voltage; and a control unit, which is used to control the opening and closing of the water supply port and the wastewater port according to the relationship between the feedback voltage and the preset voltage and the operating mode.

[0009] In some embodiments, when the second acquisition unit detects that the water supply system has entered the clean water supply mode, the control unit is configured to control the wastewater outlet to open and the water supply outlet to close when the feedback voltage is less than or equal to a first preset voltage; and to control the wastewater outlet to close and the water supply outlet to open when the feedback voltage is greater than the first preset voltage.

[0010] In some embodiments, when the second acquisition unit detects that the water supply system has entered the disinfection water supply mode, the control unit is configured to control the wastewater outlet to open and the water supply outlet to close when the feedback voltage is greater than the second preset voltage; and to control the wastewater outlet to close and the water supply outlet to open when the feedback voltage is less than or equal to the second preset voltage.

[0011] In some embodiments, the control module is configured to control both the water supply port and the first water outlet to open during the clean water supply phase.

[0012] In some embodiments, the water supply system further includes: a first water level detection element and a second water level detection element, wherein the first water level detection element is used to detect the water level in the working chamber, and the second water level detection element is used to detect the water level in the first liquid storage chamber, and both the first water level detection element and the second water level detection element are electrically connected to the control module.

[0013] In some embodiments, the body further defines: a second liquid storage chamber, the salt inlet being disposed on the second liquid storage chamber, the second liquid storage chamber having a second water outlet communicating with the working chamber, and the switch assembly being used to control the switching of the second water outlet.

[0014] In some embodiments, the body further defines a wastewater chamber, which is connected to the working chamber via the wastewater outlet.

[0015] In some embodiments, the water supply system further includes a reminder module, which is electrically connected to the control module.

[0016] An air purification device according to an embodiment of the present invention includes: a body; a humidifying component disposed on the body; a water supply system disposed on the body, wherein the water supply port of the water supply system is connected to the humidifying component to supply clean water or disinfectant water; and a fan assembly for driving air to flow through the humidifying component.

[0017] According to an embodiment of the present invention, the air purification device defines a working chamber and a first liquid storage chamber through a water supply system. The working chamber is provided with a water supply port, a wastewater port, and a salt addition port. After controlling the opening and closing of the wastewater port, the working chamber can be separately filled with a chloride-containing salt solution and clean water as needed, thus separating the processes of supplying clean water and supplying disinfectant water. This allows the air purification device to achieve disinfection mode and humidification mode respectively, avoiding the supply of chloride-containing salt solution in the humidification mode and improving the user's comfort during the air humidification stage.

[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] The following is for reference. Figure 1 The present invention describes a water supply system 100 for an air purification device according to an embodiment of the present invention. The water supply system 100 has working modes, including a clean water supply mode and a disinfected water supply mode. The water supply system 100 includes: a main body 10, a switch assembly 20, an electrolysis module 30, and a control module.

[0046] The main body 10 defines a working chamber 101 and a first storage chamber 102. The working chamber 101 has a water supply port (not shown) and a wastewater port 1012. The first storage chamber 102, which is used to store clean water, has a first outlet 1021 that communicates with the working chamber 101. The main body 10 also has a salt addition port 1001. The switch assembly 20 is used to control the switching of the water supply port, the wastewater port 1012, and the first outlet 1021 respectively. The electrolysis module 30 is disposed on the main body 10. The electrolysis module 30 is used to electrolyze the chloride-containing salt solution in the working chamber 101 to produce disinfectant water containing hypochlorous acid. The control module is electrically connected to the switch assembly 20 and the electrolysis module 30 to control the water supply system 100 to switch between different working modes.

[0047] This can be understood as follows: Under the control of the control module, when the switch assembly 20 controls the wastewater outlet 1012 of the working chamber 101 to close and the first outlet 1021 to open, clean water is supplied from the first storage chamber 102 to the working chamber 101, salt is added through the salt inlet 1001, and the electrolysis module 30 operates. At this time, the water supply system 100 is in disinfectant supply mode. When the switch assembly 20 controls the wastewater outlet 1012 of the working chamber 101 to close and the first outlet 1021 to open, clean water is supplied from the first storage chamber 102 to the working chamber 101, salt is not added through the salt inlet 1001, and the electrolysis module 30 does not operate. At this time, the water supply system 100 is in clean water supply mode. The wastewater outlet 1012 can discharge excess wastewater from the working chamber 101 to prevent bacterial growth and facilitate cleaning. It can also be used to discharge unwanted water in a timely manner to ensure the normal operation of the water supply system 100.

[0048] According to an embodiment of the present invention, the water supply system 100 of the air purification device has a main body 10 defining a working chamber 101 and a first liquid storage chamber 102. The working chamber 101 is provided with a water supply port, a wastewater port 1012 and a salt addition port 1001. By controlling the opening and closing of the wastewater port 1012, the working chamber 101 can be separately filled with a chloride-containing salt solution and clean water as needed, separating the process of supplying clean water and supplying disinfectant water. This avoids the water supplied by the air purifier in the humidification mode being a chloride-containing salt solution, thereby improving the user's comfort during the air humidification stage.

[0049] In some embodiments, such as Figure 7 As shown, each working mode has an activation phase. The control module includes: a first acquisition unit, used to acquire the feedback voltage of the electrolysis module 30; a second acquisition unit, used to acquire the working mode to which the activation phase belongs; a comparison unit, used to compare the feedback voltage with a preset voltage; and a control unit, used to control the switching of the water supply port and wastewater port 1012 according to the relationship between the feedback voltage and the preset voltage and the working mode. It can be understood that before the working chamber 101 operates again, there will be wastewater formed after the previous operation in the working chamber 101. Because the resistance of the chloride-containing solution is different from that of clean water, the voltage when the wastewater is a chloride-containing solution is also different from the voltage when it is clean water. After acquiring the feedback voltage, the first acquisition unit compares the current voltage with the preset voltage through the comparison unit, thereby determining whether the current wastewater is a chloride-containing solution or clean water. By controlling the switching of the water supply port and wastewater port 1012, wastewater is automatically discharged once before the next operation.

[0050] It is worth noting that by detecting the solution composition in the working chamber 101 through the feedback voltage of the electrolysis module 30, targeted drainage can be carried out to avoid solution mixing and unsatisfactory results in the disinfectant supply mode. For example, when switching from the clean water supply mode to the disinfectant supply mode, the water in the working chamber 101 is clean water. If salt is added directly without draining it, the salt concentration will decrease because the amount of salt added is generally fixed. This will result in insufficient electrolysis concentration, poorer disinfection effect, and a worse user experience when purifying the air.

[0051] Optionally, the preset time for the opening of the wastewater outlet 1012 controlled by the switch assembly 20 is T1. That is, when the wastewater outlet 1012 has been open for T1 time, it is considered that the wastewater in the working chamber 101 has been completely discharged. The value of T1 can be set according to specific circumstances, such as three minutes or five minutes, etc., which will not be elaborated here.

[0052] In some embodiments, when the second acquisition unit detects that the water supply system 100 has entered the clean water supply mode, the control unit is configured to control the wastewater outlet 1012 to open and the water supply outlet to close when the feedback voltage is less than or equal to a first preset voltage; and to control the wastewater outlet 1012 to close and the water supply outlet to open when the feedback voltage is greater than the first preset voltage. Since the resistance of the chloride-containing solution is less than that of clean water, the voltage in the working chamber 101 when it contains a chloride-containing solution is less than the voltage when it contains clean water. When the feedback voltage is less than or equal to the first preset voltage, it indicates that the current wastewater is a chloride-containing solution, which will affect the operation of the clean water supply mode. Therefore, the wastewater outlet 1012 is opened and the water supply outlet is closed, discharging the chloride-containing wastewater. When the feedback voltage is greater than the first preset voltage, it indicates that the current wastewater is clean water, which will not affect the operation of the clean water supply mode. Therefore, the wastewater outlet 1012 is closed and the water supply outlet is opened, and there is no need to discharge the clean water wastewater.

[0053] In some embodiments, when the second acquisition unit detects that the water supply system 100 has entered the disinfection water supply mode, the control unit is configured to control the wastewater outlet 1012 to open and the water supply outlet to close when the feedback voltage is greater than the second preset voltage; and to control the wastewater outlet 1012 to close and the water supply outlet to open when the feedback voltage is less than or equal to the second preset voltage. Based on the above analysis, when the feedback voltage is greater than or equal to the second preset voltage, it indicates that the current wastewater is clean water, which affects the operation of the disinfection water supply mode. Therefore, the wastewater outlet 1012 is opened and the water supply outlet is closed, discharging the clean water wastewater. When the feedback voltage is less than or equal to the second preset voltage, it indicates that the current wastewater is a chloride-containing solution, which does not affect the operation of the disinfection water supply mode. Therefore, the wastewater outlet 1012 is closed and the water supply outlet is opened, and there is no need to discharge the chloride-containing wastewater.

[0054] Optionally, the first preset voltage can be equal to the second preset voltage. Of course, the first preset voltage can also be different from the second preset voltage. No specific restrictions are imposed here, and it will not be elaborated further.

[0055] In some embodiments, such as Figure 6 As shown, the input power supply of the electrolysis module 30 is a constant voltage power supply. After the electrodes of the electrolysis module 30 are connected, the control module controls the voltage regulation circuit to supply a lower voltage to the electrolysis circuit and detects the current of the constant current load. If the current of the constant current load does not reach the preset current value A1, the control module will gradually increase the output voltage according to the adjustable feedback network until the load current reaches the preset value. Then the control module continues to detect the magnitude of the output current. If the current increases, the output voltage will decrease; otherwise, the output voltage will increase, so that the load current is maintained at the preset current value A1. Thus, different feedback voltages can be obtained according to the different solutions in the working chamber 101.

[0056] In some embodiments, the user is required to add salt each time the electrolyzed water enters the disinfection water supply mode. Simultaneously, the electrolysis circuit provides voltage feedback; if the voltage exceeds a first preset voltage, the user is reminded to add salt. A corresponding reminder function can be designed on the display. Furthermore, the water volume in the working chamber 101 and the disinfection and humidification time are rationally designed. For example, the disinfection time is designed to be T3. If T3 is exceeded, the disinfection function is automatically shut off, and the water volume in the working chamber 101 is equivalent to the humidification amount during T3. If the user needs to disinfect again after T3, salt must be added again before restarting the disinfection function. The value of T3 can be set according to specific circumstances and will not be elaborated here.

[0057] In some embodiments, the control module is configured to open both the water supply port and the first water outlet 1021 during the clean water supply phase. During the clean water supply phase, the working chamber 101 supplies clean water to the outside by opening the water supply port, and at the same time, the first liquid storage chamber 102 can replenish the working chamber 101 in a timely manner by opening the first water outlet 1021, ensuring normal operation.

[0058] In some embodiments, such as Figure 1 As shown, the water supply system 100 also includes a first water level detection element 40 and a second water level detection element 50. The first water level detection element 40 is used to detect the water level in the working chamber 101, and the second water level detection element 50 is used to detect the water level in the first storage chamber 102. Both the first water level detection element 40 and the second water level detection element 50 are electrically connected to the control module. It can be understood that the first water level detection element 40 can detect the lowest and highest water levels in the working chamber 101. When the lowest water level is detected, if the water level is below this height, the water pump cannot effectively pump water, and the user needs to add water. When the highest water level is detected, if the water level exceeds this height, the water in the working chamber 101 will connect with the water in the first storage chamber 102, thereby diluting the chloride-containing salt solution. Similarly, the second water level detection element 50 can detect the lowest water level in the first storage chamber 102. When the lowest water level is detected, it indicates that the water volume in the first storage chamber 102 is insufficient, and water needs to be added.

[0059] Optional, such as Figure 1 As shown, the first water level detection element 40 and the second water level detection element 50 are water level sensors. A first float 401 corresponding to the operation of the first water level detection element 40 is provided in the working chamber 101. The first water level detection element 40 determines whether the water level in the working chamber 101 is at the lowest or highest level by detecting different positions of the first float 401. Similarly, a second float 501 corresponding to the operation of the second water level detection element 50 is provided in the first liquid storage chamber 102. The first water level detection element 40 determines whether the first liquid storage chamber 102 has reached the lowest water level by sensing the second float 501.

[0060] In some embodiments, such as Figure 1As shown, the switch assembly 20 includes a first switch (not shown), a second switch 201, and a fourth switch 202. The first switch is located on the water supply port of the working chamber 101, the second switch 201 is located on the first water outlet 1021 of the first liquid storage chamber 102, and the fourth switch is located on the wastewater outlet 1012 of the working chamber 101, so that the water output of each chamber can be controlled individually.

[0061] Optionally, the first switch, the second switch 201, and the fourth switch 202 are switching valves, which are simple and easy to control.

[0062] In some embodiments, such as Figure 2 and Figure 3 As shown, taking the second switch 201 as an example, the switch valve includes a first connecting rod 2011, a seal 2012, a second connecting rod 2013, and a motor 2014. The seal 2012 is located on one side of the water supply port in the working chamber 101, for example, above the water supply port. The first connecting rod 2011 is connected to the seal 2012, so that it drives the seal 2012 to move upward to open the water supply port, and drives the seal 2012 to move downward to close the water supply port. The second connecting rod 2013 abuts against or is close to the end of the first connecting rod 2011 away from the seal 2012. The output shaft of the motor 2014 is connected to the second connecting rod 2013, so that it drives the second connecting rod 2013 to rotate. This can be understood as follows: When the water supply port is open, the motor 2014 drives the second connecting rod 2013 to rotate to a preset position, pushing the first connecting rod 2011 upwards. The seal 2012 disengages from the water supply port, and the working chamber 101 supplies water. When the water supply port is closed, the motor 2014 continues to drive the second connecting rod 2013 to rotate. The second connecting rod 2013 disengages from the first connecting rod 2011, the seal 2012 resets its seal, and water does not flow from the working chamber 101. The arrangement of the first switch on the water supply port and the arrangement of the fourth switch on the wastewater outlet 1012 can be referred to the above description and will not be repeated here.

[0063] Optionally, the seal 2012 is a sealing ring, and the motor 2014 is a stepper motor.

[0064] In some embodiments, such as Figure 1As shown, the main body 10 further defines a second liquid storage chamber 103, a salt inlet 1001 located on the second liquid storage chamber 103, and a second outlet 1031 communicating with the working chamber 101. A switch assembly 20 is used to control the opening and closing of the second outlet 1031. In other words, the second liquid storage chamber 103 is configured to contain a chloride-containing solution by adding salt, forming a chloride-containing solution tank. The switch assembly 20 controls the second outlet 1031 to add the chloride-containing solution to the working chamber 101, thus enabling multiple supply of the chloride-containing solution and meeting multiple disinfection water supply modes. Compared to frequent salt addition operations, this reduces labor intensity and provides a better user experience. Furthermore, by simultaneously providing a second liquid storage chamber 103 and a first liquid storage chamber 102, the water supply system 100 has two water storage chambers, namely a chloride-containing salt solution chamber and a clean water chamber. The chloride-containing salt solution chamber adds chloride-containing salt solution to the working chamber 101 to supply disinfectant water, and the clean water chamber adds clean water to the working chamber 101 to supply clean water, making operation more convenient.

[0065] Optionally, the salt added through the salt inlet 1001 can be a salt ball or a salt block. The salt ball or block will quickly effervesce, forming a chloride-containing salt solution. Of course, salt can also be added in other ways, which will not be elaborated here.

[0066] In some embodiments, such as Figure 1 As shown, the water supply system 100 also includes a third water level detection element 70, which is connected to the control module and is used to detect the water level in the second liquid storage chamber 103. The third water level detection element 70 can detect the lowest water level in the second liquid storage chamber 103. When the lowest water level is detected, the water volume in the second liquid storage chamber 103 is insufficient and water needs to be added.

[0067] Optionally, the third water level detection element 70 is a water level sensor. For example, a third float 701 corresponding to the operation of the third water level detection element 70 is provided in the second liquid storage chamber 103. The third water level detection element 70 can determine whether the second liquid storage chamber 103 has reached the lowest water level by sensing the third float 701.

[0068] In some embodiments, such as Figure 1 As shown, the main body 10 also defines a wastewater chamber 104, which is connected to the working chamber 101 via a wastewater outlet 1012. The wastewater chamber 104 is used to collect wastewater, preventing direct discharge and ensuring a clean and tidy environment. Once the wastewater chamber 104 has collected a set amount of wastewater, it is then discharged externally. Compared to multiple discharges, collecting wastewater through the wastewater chamber 104 improves the user experience.

[0069] In some embodiments, such as Figure 1 As shown, the water supply system 100 also includes a fourth water level detection element 80, which is connected to the control module and is used to detect the water level in the wastewater chamber 104.

[0070] Optional, such as Figure 1 As shown, a fourth float 801 corresponding to the operation of the fourth water level detection device 80 is provided in the wastewater chamber 104. The fourth water level detection device 80 can detect the position of the fourth float 801 to know the highest water level in the wastewater chamber 104. When the highest water level is detected, it means that the wastewater chamber 104 is full and needs to be drained in time.

[0071] In some embodiments, such as Figure 1 As shown, the switch assembly 20 also includes a third switch 203, which is located on the second outlet 1031 of the second liquid storage chamber 103. The third switch 203 is a switch valve, which is simple and easy to control. The arrangement of the third switch 203 on the second outlet 1031 can be referred to the above description and will not be repeated here.

[0072] In some embodiments, the water supply system 100 further includes a reminder module (not shown), which is electrically connected to the control module. The reminder module provides reminder services, for example, it can remind users of the water levels in the working chamber 101, the first liquid storage chamber 102, the second liquid storage chamber 103, and the wastewater chamber 104, and it can also remind users whether the water supply system 100 is currently in clean water supply mode or disinfected water supply mode. The reminder module can provide reminders by emitting a sound, vibration, or light, or by a combination of these methods, such as a sound and vibration, or a sound and light.

[0073] Specifically, when the control module controls the first water level detection element 40 to detect the lowest and highest water levels in the working chamber 101, the reminder module emits a prompt sound and vibration to remind the user, such as the prompt sound being "The working chamber has reached the lowest water level" or "The working chamber has reached the highest water level".

[0074] Specifically, when the control module controls the second water level detection element 50 to detect the lowest water level in the first liquid storage chamber 102, the reminder module emits a prompt sound and vibration to remind the user, such as the prompt sound being "The first liquid storage chamber has reached the lowest water level".

[0075] Specifically, when the control module controls the third water level detection element 70 to detect the lowest water level in the second liquid storage chamber 103, the reminder module emits a prompt sound and vibration to remind the user, such as the prompt sound saying "The second liquid storage chamber has reached the lowest water level".

[0076] Specifically, when the control module controls the fourth water level detection element 80 to detect the highest water level in the wastewater chamber 104, the reminder module will emit a prompt sound or vibration to remind the user. For example, the prompt sound could be "Wastewater chamber 104 has reached the highest water level".

[0077] Specifically, when the control module switches between clean water supply mode and disinfected water supply mode, the reminder module issues a voice prompt to remind the user which mode is currently in, which is more user-friendly.

[0078] It is worth noting that the specific construction of the electrolysis module 30 can be found in existing technology and will not be elaborated here. The electrolysis time of the electrolysis module 30 is set to T2, meaning that after time T2, the chloride-containing salt solution in the working chamber 101 is completely electrolyzed into disinfectant. For example, T2 can be five minutes, meaning that the chloride-containing salt solution is completely electrolyzed five minutes after the electrolysis module 30 starts. Of course, the value of T2 is not limited to this and can be other values, which will not be elaborated here.

[0079] The following describes a specific embodiment of the water supply system 100 of the present invention with reference to the accompanying drawings.

[0080] Example 1

[0081] like Figures 2 to 4 , Figure 6 and Figure 7 As shown, a water supply system 100 for an air purification device has working modes, including a clean water supply mode and a disinfected water supply mode. The water supply system 100 includes: a main body 10, a switch assembly 20, an electrolysis module 30, and a control module.

[0082] The main body 10 defines a working chamber 101 and a first storage chamber 102. The working chamber 101 has a water supply port and a wastewater port 1012. The first storage chamber 102, used for storing clean water, has a first outlet 1021 connected to the working chamber 101. The main body 10 also has a salt addition port 1001. A switch assembly 20 is used to control the switching of the water supply port, wastewater port 1012, and first outlet 1021 respectively. An electrolysis module 30 is mounted on the main body 10. The electrolysis module 30 is used to electrolyze the chloride-containing salt solution in the working chamber 101 to produce disinfectant water containing hypochlorous acid. A control module is electrically connected to the switch assembly 20 and the electrolysis module 30 to control the switching of the water supply system 100 between different working modes. The working time T2 of the electrolysis module 30 is set to 5 minutes. After the electrolysis module 30 is started for 5 minutes, the chloride-containing salt solution in the working chamber 101 is completely electrolyzed.

[0083] Each working mode has an activation phase. The control module includes: a first acquisition unit, which is used to acquire the feedback voltage of the electrolysis module 30; a second acquisition unit, which is used to acquire the working mode to which the activation phase belongs; a comparison unit, which is used to compare the magnitude of the feedback voltage with the preset voltage; and a control unit, which is used to control the switching of the water supply port and the wastewater port 1012 according to the relationship between the feedback voltage and the preset voltage and the working mode.

[0084] The first preset voltage is set to V1. When the second acquisition unit detects that the water supply system 100 has entered the clean water supply mode, the control unit is configured to open the wastewater outlet 1012 and close the water supply outlet when the feedback voltage is less than or equal to the first preset voltage; and to close the wastewater outlet 1012 and open the water supply outlet when the feedback voltage is greater than the first preset voltage. The opening time of the wastewater outlet 1012 is set to T1, after which the wastewater in the working chamber 101 is drained.

[0085] The second preset voltage is also set to V1. When the second acquisition unit detects that the water supply system 100 has entered the disinfection water supply mode, the control unit is configured to control the wastewater outlet 1012 to open and the water supply outlet to close when the feedback voltage is greater than the second preset voltage; and to control the wastewater outlet 1012 to close and the water supply outlet to open when the feedback voltage is less than or equal to the second preset voltage. The drainage time of the wastewater outlet 1012 is also T1, after which the wastewater in the working chamber 101 is emptied.

[0086] The control module is configured to open both the water supply port and the first water outlet 1021 during the clean water supply stage.

[0087] The water supply system 100 also includes: a first water level detection element 40 and a second water level detection element 50. The first water level detection element 40 is used to detect the water level in the working chamber 101, and the second water level detection element 50 is used to detect the water level in the first liquid storage chamber 102. Both the first water level detection element 40 and the second water level detection element 50 are electrically connected to the control module.

[0088] The first water level detection element 40 and the second water level detection element 50 are water level sensors. A first float 401 corresponding to the operation of the first water level detection element 40 is installed in the working chamber 101. The first water level detection element 40 determines whether the water level in the working chamber 101 is at its lowest or highest level by detecting different positions of the first float 401. The lowest water level in the working chamber 101 is marked as H2, and the highest water level as H1. A second float 501 corresponding to the operation of the second water level detection element 50 is installed in the first liquid storage chamber 102. The first water level detection element 40 determines whether the first liquid storage chamber 102 has reached its lowest water level by sensing the second float 501. The lowest water level in the first liquid storage chamber 102 is marked as H4.

[0089] The main body 10 also defines a wastewater chamber 104, which is connected to the working chamber 101 via a wastewater outlet 1012.

[0090] The water supply system 100 also includes a fourth water level detection element 80, which is connected to the control module and is used to detect the water level in the wastewater chamber 104. A fourth float 801 corresponding to the operation of the fourth water level detection element 80 is installed in the wastewater chamber 104. The fourth water level detection element 80 can detect the position of the fourth float 801 to determine the highest water level in the wastewater chamber 104. The highest water level in the wastewater chamber 104 is marked as H5. When this highest water level is detected, it indicates that the wastewater chamber 104 is full and needs to be drained promptly.

[0091] The water supply system 100 also includes a reminder module, which is electrically connected to the control module. The reminder module is used to provide reminder services.

[0092] The switch assembly 20 includes a first switch, a second switch 201, and a fourth switch 202. The first switch is located on the water supply port of the working chamber 101, the second switch 201 is located on the first water outlet 1021 of the first liquid storage chamber 102, and the fourth switch 202 is located on the wastewater outlet 1012 of the working chamber 101, so that the water output of each chamber can be controlled individually.

[0093] The first switch, second switch 201, and fourth switch 202 are switching valves, each including a first connecting rod 2011, a seal 2012, a second connecting rod 2013, and a motor 2014. The seal 2012 is located on one side of the water supply port within the working chamber 101, for example, above the water supply port. The first connecting rod 2011 connects to the seal 2012, causing the seal 2012 to move upwards to open the water supply port and downwards to close it. The second connecting rod 2013 abuts against or approaches the end of the first connecting rod 2011 furthest from the seal 2012. The output shaft of the motor 2014 is connected to the second connecting rod 2013, causing it to rotate.

[0094] Seal 2012 is a sealing ring, and motor 2014 is a stepper motor.

[0095] The following is for reference. Figure 8 The working principle of the water supply system 100 of the present invention is described as follows:

[0096] When the water supply system is turned on, the user selects a mode to determine whether to enter the disinfected water supply mode or the clean water supply mode.

[0097] In disinfectant supply mode: The system checks if the feedback voltage is greater than V1. If it is, the fourth switch 202 opens, discharging the clean water from the working chamber 101. After time T1, the fourth switch 202 closes. Next, it checks if the water level in the wastewater chamber 104 has reached the maximum level H5. If so, the fourth switch 202 closes, reminding the user to empty the collected wastewater. If the feedback voltage is less than V1, salt is added to the working chamber 101 through the salt inlet 1001.

[0098] Secondly, the first water level detection element 40 and the first float 401 cooperate to detect the water level in the working chamber 101. When the water level in the working chamber 101 reaches the set height, the water level sensor sends a signal to the control module, controlling the motor 2014 at the first outlet 1021 to close the seal 2012, preventing water from flowing out of the first outlet 1021 of the first storage chamber 102. The water level sensor is positioned below the first outlet 1021 in the height direction, ensuring that the highest water level in the working chamber 101 is always below the first outlet 1021, and the water in the first storage chamber 102 and the working chamber 101 are not connected. This is especially important when preparing a chloride-containing salt solution.

[0099] In clean water supply mode: The system checks if the feedback voltage is greater than V1. If it is, the second switch 201 opens, and the first water storage chamber 102 supplies water to the working chamber 101, activating the clean water supply function. During the water supply process, the system continues to check if the water level in the first water storage chamber 102 reaches H4. If so, the user is alerted that the first water storage chamber 102 is low on water, the second switch 201 closes, and clean water is replenished promptly. Finally, the system checks if the water level in the working chamber 101 reaches H2. If so, the function is forcibly shut down, and the water pump stops pumping water. If the feedback voltage is less than or equal to greater than V1, the fourth switch 202 opens, discharging the clean water from the working chamber 101. After time T1, the fourth switch 202 closes. Then, the system checks if the water level in the wastewater chamber 104 reaches the maximum water level H5. If so, the fourth switch 202 closes, reminding the user to empty the collected wastewater.

[0100] The electrolysis module 30 feeds back voltage to detect whether the water in the working chamber 101 is a chloride-containing solution. If it is a chloride-containing solution or hypochlorous acid water, the valve at the wastewater outlet 1012 opens, draining the wastewater from the working chamber 101 into the wastewater chamber 104, or directly to the outside through a drain pipe. For example, if this system is used in an air conditioner, the wastewater can be discharged outdoors through the air conditioner's drain pipe. The second water level detector 50 and the second float 501 detect the water level in the first liquid storage chamber 102. When there is no water in the first liquid storage chamber 102, a water shortage alarm is issued to remind the user that the first liquid storage chamber 102 needs to be filled with water. The fourth water level detector 80 and the fourth float 801 detect the water level in the wastewater chamber 104. When the water level reaches a certain height, the user is reminded that the wastewater chamber 104 needs to be emptied.

[0101] Example 2

[0102] like Figures 1 to 3 , Figure 5 , Figures 6 to 8 As shown, the structure of the water supply system 100 of the present invention is disclosed. The system structure of the second embodiment is largely the same as that of the first embodiment, and the same parts will not be described here.

[0103] The difference is that in the second embodiment, the body 10 further defines: a second liquid storage chamber 103, a salt inlet 1001 is provided on the second liquid storage chamber 103, the second liquid storage chamber 103 has a second water outlet 1031 that communicates with the working chamber 101, and the switch assembly 20 is used to control the opening and closing of the second water outlet 1031.

[0104] The water supply system 100 also includes a third water level detection element 70, which is connected to the control module and is used to detect the water level in the second liquid storage chamber 103. The third water level detection element 70 can detect the lowest water level in the second liquid storage chamber 103. When the lowest water level is detected, the water volume in the second liquid storage chamber 103 is insufficient and water needs to be added.

[0105] The third water level detection element 70 is a water level sensor. For example, a third float 701 corresponding to the operation of the third water level detection element 70 is set in the second liquid storage chamber 103. The third water level detection element 70 can determine whether the second liquid storage chamber 103 has reached the lowest water level by sensing the third float 701. The lowest water level of the second liquid storage chamber 103 is marked as H3.

[0106] The switch assembly 20 also includes a third switch 203, which is a switch valve and is located on the second outlet 1031 of the second liquid storage chamber 103.

[0107] Furthermore, in Embodiment 2, when entering the disinfectant water supply mode: if the detected feedback voltage is less than or equal to V1, the third switch 203 opens, and the second water storage chamber 103 supplies water. Then, it is determined whether the water level in the working chamber 101 reaches H1. If so, the third switch 203 closes, the electrolysis module 30 operates, and the water pump draws water from the supply port to supply disinfectant water. It is then determined whether the water level in the second water storage chamber 103 reaches H3. If so, the user is reminded that the second water storage chamber 101 is low on water, and the third switch 203 closes. Finally, it is necessary to determine whether the water level in the working chamber 101 reaches H2. If so, the function is forcibly shut down, and the water pump stops pumping water.

[0108] Secondly, a pre-prepared chloride-containing salt solution of a preset concentration is added to the working chamber 101 through the second water outlet 1031. During this process, the third water level detection element 70 and the third float 701 work together to detect the water level in the second liquid storage chamber 103. When there is no water in the second liquid storage chamber 103, a low water alarm is issued to remind the user that water needs to be added to the second liquid storage chamber 103. At this time, salt is added through the salt inlet 1001.

[0109] The air purification device 1000 of the present invention will now be described with reference to the accompanying drawings.

[0110] like Figure 9As shown, an air purification device 1000 according to an embodiment of the present invention includes: a body 200; a humidification component 300 disposed on the body 200; a water supply system 100 disposed on the body 200, the water supply port of the water supply system 100 being connected to the humidification component 300 to supply clean water or disinfectant water, wherein when the water supply system 100 supplies disinfectant water, the air purification device 1000 has a disinfection function, and when the water supply system 100 supplies clean water, the air purification device 1000 has a humidification function; and a fan assembly 400 for driving airflow through the humidification component 300.

[0111] According to an embodiment of the present invention, the air purification device 1000 defines a working chamber 101 and a first liquid storage chamber 102 through a water supply system 100 and a main body 10. The working chamber 101 is provided with a water supply port, a wastewater port 1012 and a salt addition port 1001. After controlling the opening and closing of the wastewater port 1012, the working chamber 101 can be separately filled with a chloride-containing salt solution and clean water as needed, thereby separating the process of supplying clean water and supplying disinfectant water, and realizing the disinfection mode and humidification mode of the air purification device 1000 respectively. This avoids the water supplied by the air purification device in the humidification mode being a chloride-containing salt solution, and can improve the user's comfort during the air humidification stage.

[0112] Other components of the air purification device 1000 according to embodiments of the present invention, such as the humidification component 300, the fan component 400, the electrolysis module 30, and their operation, are known to those skilled in the art and will not be described in detail here.
