Description

Technical Field

[0001] This invention relates to the field of electrical technology, and in particular to a humidifier structure and a method for detecting its water volume. Background Technology

[0002] The Industrial Revolution not only accelerated the advancement of manufacturing technology and increased the production speed of products used in society, but also made manufactured products more suitable for people's lives and work. The development of electrical appliances, in particular, ushered society into an era of electronically controlled living, making people's lives more comfortable and convenient. A humidifier is a household appliance that increases room humidity. It can humidify a specific room or be connected to a boiler or central air conditioning system to humidify an entire building, ensuring that the humidity of the environment meets people's health needs and protecting human safety. It also guarantees the humidity of the building or tools in the environment where the humidifier is used, bringing numerous conveniences to people's work and safety.

[0003] However, during the use of humidifiers, users generally do not pay too much attention to the humidifier's operating requirements, especially the water volume. When the water volume is insufficient to meet the humidifier's working conditions, the humidifier will stop working or even be damaged and unable to function. Therefore, humidifiers should be equipped with self-diagnostic devices to ensure they are always in a working state. This not only facilitates humidifier maintenance but also allows for easy activation to provide a humidified environment.

[0004] Chinese Patent Publication No. CN111207460A, published on May 29, 2020, discloses an air purifying humidifier and its usage method, comprising a housing. A first air pump is fixedly connected to the top left side of the housing. An air filter is connected to the left side of the first air pump, and an air inlet hood is connected to the left side of the air filter. A first air pipe is connected to the right side of the first air pump. The right side of the first air pipe extends into the inner cavity of the housing and is connected to a serpentine tube. An activated carbon filter element is disposed on the side of the inner cavity of the serpentine tube near the first air pipe. A dust filter screen is fixedly connected to the left side of the activated carbon filter element. The middle part of the inner cavity of the serpentine tube... A HEPA filter element is fixedly connected. A disinfection chamber is fixedly connected to the inner cavity of the serpentine tube near the bottom left side of the inner cavity. An air inlet pipe is connected to the left side of the disinfection chamber, and an air outlet pipe is connected to the right side of the disinfection chamber. A fragrance mesh plate is fixedly connected to the bottom right side of the inner cavity of the serpentine tube. A second air pump is fixedly connected to the bottom right side of the chamber. A second air pipe is connected to the left side of the second air pump. The side of the serpentine tube away from the first air pipe is connected to the left side of the second air pipe. A third air pipe is connected to the right side of the second air pump. A water tank is fixedly connected to the top right side of the inner cavity of the chamber. The top right side of the water tank and the right side... The bottom is connected to an inlet pipe and an outlet valve, respectively. The inlet pipe and outlet valve extend from the side away from the water tank to the outside of the tank body. A housing is fixedly connected to the right side of the top of the tank body. A water pump is fixedly connected to the right side of the top of the tank body, within the inner cavity of the housing. A first water pipe is connected to the bottom of the water pump, extending through the tank body to the bottom of the inner cavity of the water tank. A rubber hose is connected to the top of the water pump, and a second water pipe is connected to the top of the rubber hose. A driven gear is fixedly fitted onto the surface of the second water pipe. A motor is fixedly connected to the right side of the top of the tank body, to the left of the water pump. A rotating shaft is fixedly connected to the output end of the motor. The top of the rotating shaft is movably connected to the left side of the top of the inner wall of the housing. A driving gear that works with the driven gear is fixedly sleeved on the surface of the rotating shaft. The top of the second water pipe extends through to the outside of the housing and is connected to a pipe body. A connecting pipe is connected to the outside of the pipe body. An annular pipe is connected to the side of the connecting pipe away from the pipe body. An atomizing nozzle is connected to the top of the annular pipe. A third movable door is movably connected to the surface of the serpentine tube and to the outside of the disinfection box. A first movable door is movably connected to the left side of the front surface of the box. A controller is fixedly connected to the top of the right side of the front surface of the first movable door. Second movable doors are movably connected to both sides of the front surface of the housing.The drawback of this technical solution is that before using the humidifier, water is first poured into the water tank through the water inlet pipe, and then the water in the tank is used directly for operation. However, when pouring water into the tank, the water level is unknown, and there is no corresponding water level notification design when using the water in the tank. This means that during humidification, the water in the tank may be used up without the user's knowledge, forcing the humidifier to be stopped, thus affecting work efficiency.

[0005] In summary, installing a component that can promptly indicate the water level in the humidifier not only makes it convenient for the humidifier to be turned on at any time, but also prevents the user from turning on the humidifier when the water level is low, thus ensuring that the humidifier is not damaged during operation. Summary of the Invention

[0006] The present invention aims to overcome the shortcomings of existing technologies that cannot provide information on the amount of water available during the use of humidifiers, and provides a humidifier structure and a water level detection method that provides a prompt when the water level in the humidifier meets or does not meet the requirements for humidifier operation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A humidifier structure includes a humidification box, which has a spray pipe, a water inlet, and a water storage chamber. The spray pipe is located at the top of the humidification box, and both the spray pipe and the water inlet are connected to the water storage chamber. The humidification box is equipped with a switch assembly, a movable screen, an alarm switch one, an alarm switch two, a heating block, a microcontroller, and a display. The upper and lower ends of the water storage chamber are both Z-shaped. The width of the top and bottom ends of the water storage chamber is greater than the width of the middle end. The width of the movable screen is between the width of the top and the width of the middle end of the water storage chamber, and the outer edge of the movable screen contacts the inner wall of the humidification box. The alarm switch one is located at the upper end of the water storage chamber, and the alarm switch two is located at the lower end of the water storage chamber. The heating block is located inside the water storage chamber, and the display is located on the outer wall of the humidification box. The alarm switches one and two are both electrically connected to the microcontroller, the microcontroller is electrically connected to the display, and the display and the heating block are both electrically connected to the switch assembly.

[0009] This design allows water to be added through the water inlet on the humidifier box, flowing into the water storage chamber connected to the inlet. As the water flows into the storage chamber, the moving screen inside is buoyed by the water flow and floats towards the top of the chamber. The top and bottom of the storage chamber are both Z-shaped, with the width of the top and bottom exceeding the width of the middle. The width of the moving screen falls between the width of the top and middle of the storage chamber, and its outer edge contacts the inner wall of the humidifier box. Therefore, during the floating process, the moving screen... It will not detach from the water storage chamber and can move smoothly upwards within it. Furthermore, an alarm switch is installed at the upper end of the water storage chamber, and an alarm switch is installed at the lower end. Both alarm switches are electrically connected to a microcontroller, which in turn is electrically connected to a display. When the screen floats upwards, it will touch alarm switch one, which will then transmit information that there is sufficient water flow in the storage chamber to the microcontroller. The microcontroller will then transmit this information to the display, where it will be displayed, immediately stopping the water flow from the inlet. Next, the heating element, which is electrically connected to the humidifier and located within the water storage chamber, can be activated via the switching assembly. This allows the water in the storage chamber to evaporate, and the evaporated water vapor is discharged from the spray pipe at the top of the humidifier, humidifying the external environment. During the process of water evaporation in the water storage chamber, the water flow in the chamber gradually decreases. As the water level drops, the moving screen moves downwards until it touches alarm switch two. Alarm switch two then transmits the information that the water flow is insufficient to the microcontroller, which in turn transmits the information to the display. The display shows the information, reminding the user to turn off the humidifier and add water. This achieves the purpose of providing a prompt when the water level in the humidifier is sufficient or insufficient for humidifier operation.

[0010] Preferably, a floating ring is installed on the movable screen. The floating ring is fitted onto the outer edge of the movable screen, and its width is between the width of the top of the water storage chamber and the width of the middle end of the water storage chamber. This design allows the movable screen to move up and down smoothly in the water flow environment due to buoyancy, facilitating the activation of alarm switches one and two. This allows the display to promptly alert the user whether the water level is sufficient for the humidifier to operate. The floating ring's fit on the outer edge of the movable screen, and its width within the width of the top and middle ends of the water storage chamber, ensures that the movable screen can smoothly activate alarm switches one and two during its up-and-down movement. This avoids situations where the screen is too narrow to activate alarm switches one and two, ensuring reliability and practicality.

[0011] Preferably, the diameter of the water inlet is equal to the thickness of the float ring, and the distance between the top of the water inlet and the bottom of the water storage chamber is equal to the distance between the alarm switch and the bottom of the water storage chamber. This design, with the water inlet diameter equal to the float ring thickness and the distance between the top of the water inlet and the bottom of the water storage chamber equal to the distance between the alarm switch and the bottom of the water storage chamber, allows the float ring to float and not only smoothly contact the alarm switch, indicating that the water level in the storage chamber is sufficient for the humidifier to operate, but also promptly blocks the water inlet, reducing the probability of water leakage from the storage chamber and ensuring the humidifier can operate smoothly.

[0012] Preferably, a temperature sensor is installed on the movable screen. One end of the temperature sensor is connected to the movable screen, and the other end is placed between the movable screen and the second alarm switch. The temperature sensor is electrically connected to a microcontroller. This design allows the temperature sensor installed on the movable screen to promptly sense the temperature inside the water storage chamber. Since one end of the temperature sensor is connected to the movable screen and the other end is placed between the movable screen and the second alarm switch, the temperature sensor senses the temperature of the water flow inside the storage chamber. Regardless of whether the water flow is in a heated environment, the temperature sensor transmits the water temperature information to the microcontroller electrically connected to it. The microcontroller processes the information and then transmits it to the display, showing the water temperature value. This allows for easy adjustment of the heating block's temperature to ensure the water evaporates and humidifies the water.

[0013] Preferably, the outer wall of the spray pipe is connected to the humidification box. The spray pipe includes a first mist outlet and a second mist outlet, which are respectively located at the top and bottom of the spray pipe. A first wire mesh and a second wire mesh are installed inside the spray pipe. One end of the first wire mesh and one end of the second wire mesh are detachably connected, and the other ends of both wire mesh are in contact with the spray pipe. This design, with the spray pipe connected to the humidification box via its outer wall, allows the water vapor evaporated from the water storage chamber inside the humidification box to be smoothly discharged, thus enabling the humidifier to perform its humidification function. The spray pipe here includes mist outlet one and mist outlet two, which are located at the top and bottom of the spray pipe, respectively. The wire mesh one and wire mesh two installed inside the spray pipe are in a state where one end of wire mesh one and one end of wire mesh two are detachably connected, and the other ends of wire mesh one and wire mesh two are in contact with the spray pipe. By controlling wire mesh one and wire mesh two, the other ends of wire mesh one and wire mesh two can be brought into contact with the pipe wall and moved downwards under the guidance of the pipe wall. When they reach the position of mist outlet two, one end of wire mesh one and one end of wire mesh two are connected smoothly. This allows mist outlet two to be in an environment where water vapor is filtered by the wire mesh, while also preventing external objects from entering the water storage chamber from the spray pipe. The water storage chamber only allows water flow to enter the humidification process, ensuring smooth and reliable humidification.

[0014] Preferably, a rolling shaft is installed on the first wire mesh, and the rolling shaft is located at the lower end of one end of the first wire mesh. The second wire mesh is connected to the first wire mesh through the rolling shaft. A slot is provided at the upper end of one end of the first wire mesh, and an insert is installed on the second wire mesh, the insert matching the slot. This design, using a rolling shaft mounted on wire mesh one, allows wire mesh two to be connected to wire mesh one via the rolling shaft. The rolling shaft also allows wire mesh one and wire mesh two to smoothly rotate under the limiting conditions of the rolling shaft. The rolling shaft is located at the lower end of one end of wire mesh one, while a slot is provided at the upper end of one end of wire mesh one. The insert on wire mesh two matches the slot. Thus, when the rolling shaft rotates wire mesh one and wire mesh two, the insert on wire mesh two can be inserted into the slot of wire mesh one, resulting in a single wire mesh. Furthermore, the rotation of wire mesh one and wire mesh two can only be in one direction; due to the limitation of the slot and the insert, rotation in the other direction is not allowed. This ensures that the wire mesh formed by the connection of wire mesh one and wire mesh two can effectively block the position of the mist nozzle two, preventing external objects from entering the water storage chamber from the spray pipe. The connection method between wire mesh one and wire mesh two is also convenient for the formation and disassembly of the wire mesh, making it simple and practical.

[0015] Preferably, the inner wall of the spray pipe is provided with a limiting groove, the top of the limiting groove forms an obtuse angle α with the inner wall of the spray pipe, the bottom of the limiting groove is placed at the second mist outlet, and the sum of the widths of the first wire mesh and the second wire mesh is equal to the width of the bottom of the limiting groove. This design allows wire mesh one and wire mesh two to move up and down under the guidance of a limiting groove on the inner wall of the spray pipe. The top of the limiting groove forms an obtuse angle α with the inner wall of the spray pipe, while the bottom of the limiting groove is positioned at the mist outlet two. The sum of the widths of wire mesh one and wire mesh two is equal to the width of the bottom of the limiting groove. The other ends of wire mesh one and wire mesh two can then be inserted from one of the mist outlets of the spray pipe, allowing them to move along the spray pipe to the limiting groove position. When the other ends of wire mesh one and wire mesh two reach the mist outlet two, they are blocked by the humidification box and cannot move further down. Meanwhile, one end of wire mesh one and one end of wire mesh two are smoothly rotated under the limiting of the rolling shaft until the insert on wire mesh two is inserted into the slot on wire mesh one. At the same time, wire mesh one and wire mesh two form a wire mesh structure, preventing external objects from entering the water storage chamber through the spray pipe.

[0016] Preferably, two sockets are installed on the limiting groove, with the two sockets located at the left and right ends of the spray pipe, respectively. The sockets are electrically connected to the switch assembly. Plugs are installed on the other end of both the first and second wire meshes, with each plug corresponding to a socket. This design allows the plugs on the other ends of the wire meshes to be easily inserted into the sockets on the limiting groove when the first and second wire meshes are moved to form a wire mesh state. This ensures the electrical connection between the wire meshes and the switch assembly. The switch assembly then controls the heating of the wire meshes. When the water vapor evaporates from the water storage chamber, it is still heated by the wire meshes to prevent it from liquefying and dripping back into the water storage chamber when exposed to the cold outside air. This ensures the humidifier operates smoothly.

[0017] Preferably, the humidifier box has a drain outlet at its bottom, and a plug is installed at the drain outlet to match it. A water guide block is fitted around the heating block and placed at the bottom of the water storage chamber. The water guide block is installed at the edge of the drain outlet, and its cross-sectional shape is triangular. This design, by controlling the plug, allows the drain outlet at the bottom of the humidifier box to be opened, enabling the water in the water storage chamber to drain smoothly and facilitate water replacement. The triangular water guide block at the bottom of the water storage chamber ensures that all the water in the chamber can drain smoothly. Since the water guide block is installed outside the heating block, not only can the water draining be carried out smoothly, but the heating and evaporation of the water in the storage chamber can also proceed smoothly, achieving two functions with one component.

[0018] The present invention also provides a method for detecting the water volume of a humidifier, specifically including the following steps:

[0019] Step 1: Block the drain outlet and inject water into the water storage chamber through the water inlet until the display shows that the water flow in the storage chamber meets the requirements, then stop injecting water through the water inlet.

[0020] Step 2: Start using the humidifier and let the water in the storage chamber flow out in the form of water vapor. When the display shows that the water in the storage chamber is no longer sufficient for humidification, stop the humidifier immediately.

[0021] Step 3: Continue to pour water into the water inlet to ensure that the water volume in the water storage chamber meets the humidifier's operating requirements. Repeat this process to allow the humidifier to be used for humidification for an extended period of time.

[0022] The beneficial effects of this invention are: it can provide a prompt when the water level in the humidifier is sufficient or insufficient for the humidifier to operate; it can prevent water vapor from condensing and dripping back into the water storage chamber when it is discharged; and it facilitates the installation and removal of wire mesh one and wire mesh two.

[0031] The invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 5 In the illustrated embodiment, a humidifier structure includes a humidification box 1. The humidification box 1 is equipped with a spray pipe 2, a water inlet 3, and a water storage chamber 9. The spray pipe 2 is located at the top of the humidification box 1, and both the spray pipe 2 and the water inlet 3 are connected to the water storage chamber 9. The humidification box 1 is equipped with a switch assembly 5, a movable screen 10, an alarm switch one 11, an alarm switch two 12, a heating block 15, a microcontroller 8, and a display 7. The upper and lower ends of the water storage chamber 9 are both Z-shaped, and the width of the top and bottom ends of the water storage chamber 9 is greater than the width of the middle end of the water storage chamber 9. The width of the movable screen 10 is between the width of the top of the water storage cavity 9 and the width of the middle end of the water storage cavity 9. The outer edge of the movable screen 10 is in contact with the inner wall of the humidification box 1. Alarm switch 11 is located at the upper end of the water storage cavity 9, and alarm switch 12 is located at the lower end of the water storage cavity 9. The heating block 15 is located inside the water storage cavity 9. The display 7 is located on the outer wall of the humidification box 1. Alarm switch 11 and alarm switch 12 are both electrically connected to the microcontroller 8. The microcontroller 8 is electrically connected to the display 7. The display 7 and the heating block 15 are both electrically connected to the switch assembly 5.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a floating ring 18 is installed on the movable screen 10. The floating ring 18 is fitted onto the outer edge of the movable screen 10, and its width is between the width of the top of the water storage chamber 9 and the width of the middle end of the water storage chamber 9. The diameter of the water inlet 3 is equal to the thickness of the floating ring 18, and the distance between the top of the water inlet 3 and the bottom of the water storage chamber 9 is equal to the distance between the alarm switch 11 and the bottom of the water storage chamber 9. A temperature sensor 13 is installed on the movable screen 10. One end of the temperature sensor 13 is connected to the movable screen 10, and the other end of the temperature sensor 13 is placed between the movable screen 10 and the alarm switch 12. The temperature sensor 13 is electrically connected to the microcontroller 8.

[0034] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the outer wall of the spray pipe 2 is connected to the humidification box 1. The spray pipe 2 includes a first mist outlet 19 and a second mist outlet 20, which are located at the top and bottom of the spray pipe 2, respectively. A first wire mesh 22 and a second wire mesh 23 are installed inside the spray pipe 2. One end of the first wire mesh 22 and one end of the second wire mesh 23 are detachably connected. The other ends of both the first and second wire mesh 22 and the second wire mesh 23 are in contact with the spray pipe 2. A rolling shaft 26 is installed on the first wire mesh 22, located at the lower end of one end of the first wire mesh 22. The second wire mesh 23 is connected to the first wire mesh 22 via the rolling shaft 26. A slot 4 is provided at the upper end of one end of the first wire mesh 22, and an insert 6 is installed on the second wire mesh 23, which matches the slot 4. A limiting groove 21 is provided on the inner wall of the spray pipe 2. The top of the limiting groove 21 forms an obtuse angle α with the inner wall of the spray pipe 2. The bottom end of the limiting groove 21 is located at the second mist outlet 20. The sum of the widths of the first wire mesh 22 and the second wire mesh 23 is equal to the width of the bottom end of the limiting groove 21. Two sockets 24 are installed on the limiting groove 21. The two sockets 24 are located at the left and right ends of the spray pipe 2, respectively. The sockets 24 are electrically connected to the switch assembly 5. Plugs 25 are installed on the other end of the first wire mesh 22 and the other end of the second wire mesh 23. The plugs 25 correspond one-to-one with the sockets 24. The bottom of the humidification box 1 is provided with a drain outlet 16. A plug 17 is installed at the drain outlet 16. The plug 17 matches the drain outlet 16. A water guide block 14 is fitted around the heating block 15. The water guide block 14 is located at the bottom of the water storage chamber 9 and is installed at the edge of the drain outlet 16. The cross-sectional shape of the water guide block 14 is triangular.

[0035] The present invention also provides a method for detecting the water volume of a humidifier, which specifically includes the following steps:

[0036] Step 1: Block the drain outlet 16 with the plug 17, and inject water into the water storage chamber 9 through the water inlet 3 until the display 7 shows that the water flow in the water storage chamber 9 meets the requirements, then stop injecting water at the water inlet 3.

[0037] Specifically: First, block the drain outlet 16 at the bottom of the humidifier box 1 with the plug 17. Then, place the humidifier box 1 in the environment that needs humidification. When the humidifier box 1 is placed, the bottom of the humidifier box 1 should be in a state parallel to the plane. This will prevent water from leaking out of the water inlet 3 when water is injected into the water storage chamber 9 inside the humidifier box 1 or when the water is full. Water can then be smoothly injected through the inlet 3. The water flows into the storage chamber 9 connected to the inlet 3. The upper and lower ends of the storage chamber 9 are Z-shaped. The width of the top and bottom ends of the storage chamber 9 is greater than the width of the middle end. The movable screen 10 inside the storage chamber 9 is fitted with a floating ring 18. The width of the floating ring 18 is between the width of the top end and the width of the middle end of the storage chamber 9. When water is introduced through the inlet 3, it can smoothly pass through the movable screen 10 and be placed inside the storage chamber 9. The floating ring 18 is buoyed by the water flow and can move up and down smoothly when the water level changes. Moreover, due to the influence of the width of the floating ring 18 and the width and shape of the storage chamber 9, the movable screen 10 will not detach from the storage chamber 9, and the up and down movement of the movable screen 10 can be carried out safely.

[0038] An alarm switch 11 is installed at the upper end of the water storage chamber 9, and an alarm switch 212 is installed at the lower end of the water storage chamber 9. Both alarm switches 11 and 212 are electrically connected to the microcontroller 8, which is electrically connected to the display 7 on the outer wall of the humidifier box 1. When the incoming water flow moves the moving screen 10 upward until the float ring 18 touches the alarm switch 11, the alarm switch 11 will transmit the information that the water level in the water storage chamber 9 meets the water level requirements for the humidifier to the microcontroller 8. After processing by the microcontroller 8, this information will be transmitted to the display 7, which will then show the information. At this point, the water flow should be stopped immediately to resume the incoming water flow. When the movable screen 10 moves upward to the touch alarm switch 11, the float ring 18 is also positioned at the water inlet 3. This indicates that the float ring 18 not only moves the movable screen 10 up and down to fulfill the function of touching the alarm switch 11, but also reduces water leakage from the water inlet 3 into the water storage chamber 9, ensuring safety and practicality. Of course, when the display 7 shows that the water level in the water storage chamber 9 meets the requirements for humidifier operation, the water inlet 3 can be blocked to ensure that water does not leak from it.

[0039] Step 2: Start using the humidifier and let the water in the water storage chamber 9 flow out in the form of water vapor. When the display 7 shows that the water in the water storage chamber 9 is no longer sufficient for humidification, stop the humidifier immediately.

[0040] Specifically: The humidifier can then begin humidification. The switch assembly 5 installed on the humidifier box 1 can start the heating block 15 at the bottom of the water storage chamber 9. In this way, the water in the water storage chamber 9 will evaporate into water vapor under the heating environment of the heating block 15. The temperature sensor 13 installed on the moving screen 10 is connected to the moving screen 10 at one end and placed between the moving screen 10 and the alarm switch 12 at the other end. The temperature sensor 13 constantly senses the temperature information of the water flow. Moreover, the temperature sensor 13 is also electrically connected to the microcontroller 8. The temperature sensor 13 can transmit the sensed temperature to the microcontroller 8. After the microcontroller 8 processes it, it is displayed on the display 7. If the heating temperature of the heating block 15 does not meet the evaporation temperature of the water flow, the heating temperature value of the heating block 15 needs to be increased immediately to ensure that the water flow is heated and evaporated. After the water is heated and evaporates into steam, it can be discharged from the spray pipe 2. The top and bottom of the spray pipe 2 are respectively provided with a first mist outlet 19 and a second mist outlet 20. A limiting groove 21 is provided at the second mist outlet 20. The top of the limiting groove 21 forms an obtuse angle α with the inner wall of the spray pipe 2, and the bottom of the limiting groove 21 is placed at the second mist outlet 20. Then, the ends of the wire mesh 1 22 and the wire mesh 23 with plugs 25 installed can be inserted through the first mist outlet 19. Under the guiding effect of the spray pipe 2, the wire mesh 1 22 and the wire mesh 23 can move smoothly down until they touch the connection of the spray pipe 2. The humidifier box 1 is mounted on a rotating shaft 26 at the lower end of the other end of the wire mesh 22. The wire mesh 23 is connected to the wire mesh 22 via the rotating shaft 26. This not only limits the wire mesh 22 and the wire mesh 23 from separating, but also allows the wire mesh 22 and the wire mesh 23 to rotate towards each other until the insert 6 installed on the wire mesh 23 is inserted into the slot 4 on the wire mesh 22. This allows the wire mesh 22 and the wire mesh 23 to be connected to form a wire mesh. With the cooperation of the slot 4, the insert 6 and the rotating shaft 26, the wire mesh 22 and the wire mesh 23 cannot be reversed. At this time, the plugs 25 on wire mesh 1 22 and wire mesh 23 are inserted into the socket 24 installed in the limiting groove 21. The socket 24 is electrically connected to the switch assembly 5. The switch assembly 5 can also heat wire mesh 1 22 and wire mesh 23 to prevent the water vapor evaporated in the water storage chamber 9 from being cooled and liquefied into water and dripping back into the water storage chamber 9.

[0041] Meanwhile, the exhaust of water vapor will gradually reduce the water flow in the water storage chamber 9, and the water level will gradually drop. The moving screen 10 will also descend under the buoyancy of the floating ring 18 until it touches the alarm switch 12. The alarm switch 12 will then transmit this information to the microcontroller 8. The microcontroller 8 will process the information and then transmit it to the display 7, which will show that the water level is insufficient. This not only achieves the purpose of providing a prompt when the water level in the humidifier is sufficient or insufficient, but also allows the user to know that humidification should be stopped immediately to ensure that the humidifier will not burn out due to insufficient water flow, allowing the humidifier to be used for a long time.

[0042] Step 3: Continue to inject water from the water inlet 3 to ensure that the water volume in the water storage chamber 9 meets the water volume required for the humidifier to work. Repeat this process to allow the humidifier to be used for humidification for a long time.

[0043] Specifically, water can then be injected through the water inlet 3. The water flow in the water storage chamber 9 meets the humidifier's operating requirements, and this cycle repeats, allowing the humidifier to operate continuously. During the water injection and evaporation process, the display 7 constantly shows whether the water level in the water storage chamber 9 meets the humidification requirements, ensuring safe humidification. Meanwhile, the heating block 15 is fitted inside the water guide block 14, which has a triangular cross-sectional shape and is installed at the edge of the drain outlet 16. When the humidifier finishes its work and the water in the water storage chamber 9 needs to be drained, the plug 17 can be removed, allowing the water in the water storage chamber 9 to drain smoothly from the drain outlet 16. The water guide block 14 ensures that all the water in the water storage chamber 9 can be drained. The heating block 15 not only guides the water out but also heats and evaporates it, providing two functions in one component—a cost-effective and reliable solution.

[0044] First, block the drain outlet 16 at the bottom of the humidifier box 1 with the plug 17. Then, place the humidifier box 1 in the environment where humidification is needed. When the humidifier box 1 is placed, the bottom of the humidifier box 1 should be in a state parallel to the plane. This will prevent water from leaking out of the water inlet 3 when water is injected into the water storage chamber 9 inside the humidifier box 1 or when the water is full. Water can then be smoothly injected through the inlet 3. The water flows into the storage chamber 9 connected to the inlet 3. The upper and lower ends of the storage chamber 9 are Z-shaped. The width of the top and bottom ends of the storage chamber 9 is greater than the width of the middle end. The movable screen 10 inside the storage chamber 9 is fitted with a floating ring 18. The width of the floating ring 18 is between the width of the top end and the width of the middle end of the storage chamber 9. When water is introduced through the inlet 3, it can smoothly pass through the movable screen 10 and be placed inside the storage chamber 9. The floating ring 18 is buoyed by the water flow and can move up and down smoothly when the water level changes. Moreover, due to the influence of the width of the floating ring 18 and the width and shape of the storage chamber 9, the movable screen 10 will not detach from the storage chamber 9, and the up and down movement of the movable screen 10 can be carried out safely.

[0045] An alarm switch 11 is installed at the upper end of the water storage chamber 9, and an alarm switch 212 is installed at the lower end of the water storage chamber 9. Both alarm switches 11 and 212 are electrically connected to the microcontroller 8, which is electrically connected to the display 7 on the outer wall of the humidifier box 1. When the incoming water flow moves the moving screen 10 upward until the float ring 18 touches the alarm switch 11, the alarm switch 11 will transmit the information that the water level in the water storage chamber 9 meets the water level requirements for the humidifier to the microcontroller 8. After processing by the microcontroller 8, this information will be transmitted to the display 7, which will then show the information. At this point, the water flow should be stopped immediately to resume the incoming water flow. When the movable screen 10 moves upward to the touch alarm switch 11, the float ring 18 is also positioned at the water inlet 3. This indicates that the float ring 18 not only moves the movable screen 10 up and down to fulfill the function of touching the alarm switch 11, but also reduces water leakage from the water inlet 3 into the water storage chamber 9, ensuring safety and practicality. Of course, when the display 7 shows that the water level in the water storage chamber 9 meets the requirements for humidifier operation, the water inlet 3 can be blocked to ensure that water does not leak from it.

[0046] Next, the humidifier can begin humidifying. The switch assembly 5 installed on the humidifier box 1 can start the heating block 15 at the bottom of the water storage chamber 9 to start heating. In this way, the water in the water storage chamber 9 will evaporate into water vapor under the heating environment of the heating block 15. The temperature sensor 13 installed on the moving screen 10 is connected to the moving screen 10 at one end and placed between the moving screen 10 and the alarm switch 12 at the other end. The temperature sensor 13 constantly senses the temperature information of the water flow. Moreover, the temperature sensor 13 is also electrically connected to the microcontroller 8. The temperature sensor 13 can transmit the sensed temperature to the microcontroller 8. After the microcontroller 8 processes it, it is displayed on the display 7. If the heating temperature of the heating block 15 does not meet the evaporation temperature of the water flow, the heating temperature value of the heating block 15 needs to be increased immediately to ensure that the water flow is heated and evaporated. After the water is heated and evaporates into steam, it can be discharged from the spray pipe 2. The top and bottom of the spray pipe 2 are respectively provided with a first mist outlet 19 and a second mist outlet 20. A limiting groove 21 is provided at the second mist outlet 20. The top of the limiting groove 21 forms an obtuse angle α with the inner wall of the spray pipe 2, and the bottom of the limiting groove 21 is placed at the second mist outlet 20. Then, the ends of the wire mesh 1 22 and the wire mesh 23 with plugs 25 installed can be inserted through the first mist outlet 19. Under the guiding effect of the spray pipe 2, the wire mesh 1 22 and the wire mesh 23 can move smoothly down until they touch the connection of the spray pipe 2. The humidifier box 1 is mounted on a rotating shaft 26 at the lower end of the other end of the wire mesh 22. The wire mesh 23 is connected to the wire mesh 22 via the rotating shaft 26. This not only limits the wire mesh 22 and the wire mesh 23 from separating, but also allows the wire mesh 22 and the wire mesh 23 to rotate towards each other until the insert 6 installed on the wire mesh 23 is inserted into the slot 4 on the wire mesh 22. This allows the wire mesh 22 and the wire mesh 23 to be connected to form a wire mesh. With the cooperation of the slot 4, the insert 6 and the rotating shaft 26, the wire mesh 22 and the wire mesh 23 cannot be reversed. At this time, the plugs 25 on wire mesh 1 22 and wire mesh 23 are inserted into the socket 24 installed in the limiting groove 21. The socket 24 is electrically connected to the switch assembly 5. The switch assembly 5 can also heat wire mesh 1 22 and wire mesh 23 to prevent the water vapor evaporated in the water storage chamber 9 from being cooled and liquefied into water and dripping back into the water storage chamber 9.

[0047] Meanwhile, the discharge of water vapor will gradually reduce the water flow in the water storage chamber 9, and the water level will gradually drop. The moving screen 10 will also descend under the buoyancy of the floating ring 18 until it touches the alarm switch 12. The alarm switch 12 will then transmit this information to the microcontroller 8. The microcontroller 8 will process the information and then transmit it to the display 7, which will show that the water level is insufficient. This not only achieves the purpose of providing a prompt when the water level in the humidifier is sufficient or insufficient, but also allows the user to know that humidification should be stopped immediately to ensure that the humidifier will not burn out due to insufficient water flow, allowing the humidifier to be used for a long time.

[0048] Next, water can be injected through the water inlet 3. The water flow in the water storage chamber 9 meets the humidifier's operating requirements, and this cycle repeats, allowing the humidifier to be used for humidification for an extended period. During the water injection and evaporation process, the display 7 continuously monitors whether the water level in the water storage chamber 9 meets the humidification requirements, ensuring safe humidification operation. Meanwhile, the heating block 15 is housed within the water guide block 14, which has a triangular cross-sectional shape and is installed at the edge of the drain outlet 16. When the humidifier finishes its work and the water in the water storage chamber 9 needs to be drained, the plug 17 can be removed, allowing the water in the water storage chamber 9 to drain smoothly from the drain outlet 16. The water guide block 14 ensures that all the water in the water storage chamber 9 can be drained. The heating block 15 not only guides the water out but also heats and evaporates it, providing two functions in one component—a cost-effective and reliable solution.

[0049] The heating block 15, wire mesh 22, and wire mesh 23 can all be made of iron with increased resistivity. This not only allows for better heat generation due to the high resistivity when energized, but it is also inexpensive and easy to replace. The water guide block 14 can be made of copper, which has low resistivity and is sturdy and durable. To ensure safety during humidifier use, a copper wire mesh can be installed on the mist outlet 19. This prevents electric shock from contact with wire mesh 22 and wire mesh 23 when the wire mesh is inserted into the spray pipe 2.
