Description

Technical Field

[0001] The utility model relates to the field of humidifiers, in particular to a humidifier which can be automatically started and stopped according to ambient humidity. Background Art

[0002] With the rapid development of purifiers, purifiers have entered more and more households, and people have more and more usage scenarios for purifiers, and more and more diversified product demands, including humidifiers that can meet diverse needs. Traditional humidifiers usually use fixed wet curtains, which cannot realize the lifting function of the wet curtains, thus limiting the improvement of humidification and disinfection effects. Utility Model Content

[0003] The utility model aims to solve the technical problem of how to realize the lifting function of the wet curtain plate, and provides a humidifier which can automatically start and stop according to the ambient humidity.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a humidifier that can automatically start and stop according to the ambient humidity includes a controller, a humidity sensor, a humidifying shell, a lifting mechanism, a water purification box, a disinfection box, an air inlet, an air outlet, a centrifugal fan, a first wet curtain plate, and a second wet curtain plate. The controller is arranged on the outer surface of the humidifying shell and is fixedly connected to the humidifying shell. The humidity sensor is arranged on the outer surface of the humidifying shell, is fixedly connected to the humidifying shell, and is electrically connected to the controller. The lifting mechanism is arranged outside the humidifying shell, is connected to the humidifying shell, and is electrically connected to the controller. The water purification box is arranged inside the humidifying shell, and the bottom surface is slidably connected to the bottom surface inside the humidifying shell. The disinfection box is arranged inside the humidifying shell, arranged on the side of the water purification box, the side wall of the disinfection box is fixedly connected to the side wall of the water purification box close to the disinfection box, and the bottom surface of the disinfection box is slidably connected to the bottom surface inside the humidifying shell. The air inlet is arranged on the side of the humidifying shell close to the water purification box, and is connected to the humidifying shell. The air outlet is arranged on the side of the humidifying shell close to the disinfection box, and is connected to the humidifying shell. The centrifugal fan is arranged inside the humidification housing and fixedly connected to the inner wall of the humidification housing near the air outlet. The centrifugal fan covers the air outlet. The first wet curtain plate is vertically arranged inside the humidification housing, arranged just above the water purification box, and matched with the water purification box. The first wet curtain plate is connected to the lifting mechanism. The second wet curtain plate is vertically arranged inside the humidification housing, arranged just above the disinfection box, and matched with the disinfection box. The second wet curtain plate is connected to the lifting mechanism.

[0005] The humidity sensor will continuously detect the humidity of the surrounding environment and transmit the detected humidity data to the controller. After receiving the humidity data, the controller will determine whether the humidifier needs to be started according to the preset humidity range. If the ambient humidity is lower than the set value, the controller will send a command to the lifting mechanism. After receiving the command from the controller, the lifting mechanism will start and drive the first wet curtain plate and the second wet curtain plate to rise and fall synchronously. The first wet curtain plate and the second wet curtain plate will be immersed in the water purification box and the disinfection box respectively to absorb moisture and disinfectant. At the same time, the controller will also start the centrifugal fan. The centrifugal fan starts to rotate and sucks the external air into the humidification housing from the air inlet. When the air passes through the first wet curtain plate, the moisture is evaporated into the air, thereby increasing the air humidity. Then, the air passes through the second wet curtain plate, and the disinfectant is also evaporated into the air to disinfect the air. The humidified and disinfected air is discharged into the environment through the air outlet. When the humidity sensor detects that the ambient humidity reaches or exceeds the set value, the controller will send a command to the lifting mechanism and the centrifugal fan to stop working, thereby achieving automatic shutdown. The humidifier can not only increase the humidity of the air, but also disinfect the air by evaporating the disinfectant through the second wet curtain plate, thereby improving the cleanliness of the indoor air.

[0006] Further: the lifting mechanism includes a forward and reverse motor, a first threaded hole, a second threaded hole, a first threaded rod, a second threaded rod, a first gear, and a second gear. The first gear is arranged above the humidification housing. The forward and reverse motor is arranged above the humidification housing, arranged above the first gear, fixedly connected to the humidification housing, and electrically connected to the controller. The output end of the forward and reverse motor is fixedly connected to the center of the first gear. The second gear is arranged on the side of the first gear, arranged above the humidification housing, and meshed with the first gear. The first threaded rod vertically penetrates the top of the humidification housing, the top of the first threaded rod is fixedly connected to the first gear, the bottom end extends to the inside of the humidification housing, and the first threaded rod coincides with the rotation axis of the first gear. The second threaded rod is arranged on the side of the first threaded rod, the second threaded rod vertically penetrates the top of the humidification housing, the top of the second threaded rod is fixedly connected to the second gear, the bottom end extends to the inside of the humidification housing, and the second threaded rod coincides with the rotation axis of the second gear. The internal thread of the first threaded hole is left-handed, the first threaded hole is arranged inside the humidification housing, and is arranged on the side of the first wet curtain plate, and the first threaded hole is threadedly connected to the first threaded rod. The inner thread of the second threaded hole is right-handed. The second threaded hole is arranged inside the humidifying shell and on the side of the second wet curtain plate. The second threaded hole is threadedly connected with the second threaded rod.

[0007] The humidity sensor continuously detects the humidity of the surrounding environment and transmits the detected humidity data to the controller. After receiving the humidity data, the controller determines whether the humidifier needs to be started according to the preset humidity range. If the ambient humidity is lower than the set value, the controller sends a start command to the forward and reverse motor. After receiving the command, the forward and reverse motor starts working and drives the first gear fixedly connected to its output end to rotate. The rotation of the first gear drives the second gear meshed with it to rotate in the opposite direction. This gear transmission method ensures that the two threaded rods can rotate synchronously but in opposite directions. Since the thread rotation direction of the first threaded hole is left-handed, the first threaded rod will drive the first wet curtain plate connected to it to move downward when it rotates; and the thread rotation direction of the second threaded hole is right-handed, and the second threaded rod will drive the second wet curtain plate connected to it to move downward when it rotates. This design allows the two wet curtain plates to rise and fall at the same time without interfering with each other. As the first threaded rod and the second threaded rod continue to rotate, the first wet curtain plate and the second wet curtain plate are immersed in the water purification box and the disinfection box respectively to absorb water and disinfectant. When the preset position is reached or the humidity reaches the standard, the controller will send a command to reverse the forward and reverse motors, thereby driving the wet curtain to rise. While the wet curtain is descending and immersed in liquid, the humidifier can start its humidification and disinfection work, and discharge the humidified and disinfected air into the environment. Through the cooperation of gear transmission and threaded rods, the synchronous lifting and lowering of the first wet curtain and the second wet curtain is achieved, ensuring the synchronous humidification and disinfection process.

[0008] Further: comprising a switch door. The switch door is arranged on the side of the humidifier housing near the air outlet, arranged below the air outlet, communicated with the side of the humidifier housing, and matched with the disinfection box.

[0009] When it is necessary to add disinfectant to the humidifier or replace the disinfectant, the user can open the switch door to directly access the disinfection box. This makes it easy to maintain and manage the disinfection box, ensuring that the disinfection effect of the humidifier is always maintained in the best condition.

[0010] Further: the outer surface of the forward and reverse motor is provided with a moisture-proof coating.

[0011] The moisture-proof coating can effectively isolate the humid air in the environment and prevent moisture from directly contacting the metal parts of the motor. This can prevent the motor from rusting or short-circuiting due to moisture, thereby extending the service life of the motor.

[0012] Further: the first threaded rod is made of stainless steel.

[0013] Stainless steel has extremely high strength and hardness and can withstand large torque and tension, ensuring that during the operation of the humidifier, the first threaded rod can stably and reliably drive the wet curtain plate to move up and down.

[0014] Further: the second threaded rod is made of stainless steel.

[0015] Stainless steel has excellent corrosion resistance, especially in humid environments, and is not easy to rust or corrode. This feature allows the second threaded rod to maintain its original mechanical properties and appearance quality even when in contact with water for a long time, thereby extending the service life of the humidifier.

[0016] Beneficial effects of the utility model:

[0017] 1. Through the cooperation of gear transmission and threaded rod, the synchronous lifting and lowering of the first wet curtain plate and the second wet curtain plate are realized, ensuring the synchronous humidification and disinfection processes.

[0018] 2. The humidifier can not only increase the humidity of the air, but also disinfect the air by evaporating the disinfectant through the second wet curtain plate, thereby improving the cleanliness of the indoor air. BRIEF DESCRIPTION OF THE DRAWINGS

The second wet curtain plate 6 is vertically arranged inside the humidifying housing 7, and is arranged directly above the disinfection box 14, and cooperates with the disinfection box 14, and the second wet curtain plate 6 is connected to the lifting mechanism.

[0023] The humidity sensor will continuously detect the humidity of the surrounding environment and transmit the detected humidity data to the controller. After receiving the humidity data, the controller will determine whether the humidifier needs to be started according to the preset humidity range. If the ambient humidity is lower than the set value, the controller will send an instruction to the lifting mechanism. After receiving the instruction from the controller, the lifting mechanism will start and drive the first wet curtain plate 3 and the second wet curtain plate 6 to rise and fall synchronously. The first wet curtain plate 3 and the second wet curtain plate 6 will be immersed in the water purification box 11 and the disinfection box 14 respectively, so as to absorb moisture and disinfectant. At the same time, the controller will also start the centrifugal fan 8. The centrifugal fan 8 starts to rotate and sucks the external air into the humidification housing 7 from the air inlet 1. When the air passes through the first wet curtain plate 3, the moisture is evaporated into the air, thereby increasing the air humidity. Then, the air passes through the second wet curtain plate 6, and the disinfectant is also evaporated into the air to disinfect the air. The humidified and disinfected air is discharged into the environment through the air outlet 9. When the humidity sensor detects that the ambient humidity reaches or exceeds the set value, the controller will send an instruction to the lifting mechanism and the centrifugal fan 8 to stop working, thereby achieving automatic shutdown. The humidifier can not only increase the humidity of the air, but also can disinfect the air by evaporating the disinfectant through the second wet curtain plate 6, thereby improving the cleanliness of the indoor air.

[0024] The lifting mechanism includes a forward and reverse motor 2, a first threaded hole 12, a second threaded hole 15, a first threaded rod 13, a second threaded rod 16, a first gear 4, and a second gear 5. The first gear 4 is arranged above the humidification housing 7. The forward and reverse motor 2 is arranged above the humidification housing 7, arranged above the first gear 4, fixedly connected to the humidification housing 7, and electrically connected to the controller. The output end of the forward and reverse motor 2 is fixedly connected to the center of the first gear 4. The second gear 5 is arranged on the side of the first gear 4, arranged above the humidification housing 7, and meshed with the first gear 4. The first threaded rod 13 vertically penetrates the top of the humidification housing 7, the top of the first threaded rod 13 is fixedly connected to the first gear 4, and the bottom extends to the inside of the humidification housing 7, and the first threaded rod 13 coincides with the rotation axis of the first gear 4.

[0025] The humidity sensor will continuously detect the humidity of the surrounding environment and transmit the detected humidity data to the controller. After receiving the humidity data, the controller will determine whether the humidifier needs to be started according to the preset humidity range. If the ambient humidity is lower than the set value, the controller will send a start command to the forward and reverse motor 2. After receiving the command, the forward and reverse motor 2 starts to work and drives the first gear 4 fixedly connected to its output end to rotate. The rotation of the first gear 4 will drive the second gear 5 meshing with it to rotate in the opposite direction. This gear transmission method ensures that the two threaded rods can rotate synchronously but in opposite directions. Since the thread rotation direction of the first threaded hole 12 is left-handed, the first threaded rod 13 will drive the first wet curtain plate 3 connected to it to move downward when it rotates; and the thread rotation direction of the second threaded hole 15 is right-handed, and the second threaded rod 16 will drive the second wet curtain plate 6 connected to it to move downward when it rotates. This design allows the two wet curtain plates to rise and fall at the same time without interfering with each other. As the first threaded rod 13 and the second threaded rod 16 continue to rotate, the first wet curtain plate 3 and the second wet curtain plate 6 are immersed in the water purification box 11 and the disinfection box 14 respectively to absorb water and disinfectant. When the preset position is reached or the humidity reaches the standard, the controller will send a command to reverse the forward and reverse motor 2, thereby driving the wet curtain plate to rise. While the wet curtain plate is descending and immersed in the liquid, the humidifier can start its humidification and disinfection work, and discharge the humidified and disinfected air into the environment. Through the cooperation of gear transmission and threaded rods, the synchronous lifting and lowering of the first wet curtain plate 3 and the second wet curtain plate 6 is achieved, ensuring the synchronous humidification and disinfection process.

[0026] The switch door 10 is provided on the side of the humidifying housing 7 close to the air outlet 9 , below the air outlet 9 , communicated with the side of the humidifying housing 7 , and matched with the disinfection box 14 .

[0027] When it is necessary to add disinfectant to the humidifier or replace the disinfectant, the user can open the switch door 10 to directly contact the disinfection box 14. In this way, the disinfection box 14 can be easily maintained and managed to ensure that the disinfection effect of the humidifier is always maintained in the best state.

[0028] The outer surface of the forward and reverse motor 2 is provided with a moisture-proof coating.

[0029] The moisture-proof coating can effectively isolate the humid air in the environment and prevent moisture from directly contacting the metal parts of the motor. This can prevent the motor from rusting or short-circuiting due to moisture, thereby extending the service life of the motor.

[0030] The first threaded rod 13 is made of stainless steel.

[0031] Stainless steel has extremely high strength and hardness, and can withstand large torque and tension, ensuring that during the operation of the humidifier, the first threaded rod 13 can stably and reliably drive the wet curtain plate to perform lifting movements.

[0032] The second threaded rod 16 is made of stainless steel.

[0033] Stainless steel has excellent corrosion resistance, especially in a humid environment, and is not easy to rust or corrode. This feature enables the second threaded rod 16 to maintain its original mechanical properties and appearance quality even when in contact with water for a long time, thereby extending the service life of the humidifier.

[0034] Working principle: The humidity sensor will continuously detect the humidity of the surrounding environment and transmit the detected humidity data to the controller. After receiving the humidity data, the controller will determine whether the humidifier needs to be started according to the preset humidity range. If the ambient humidity is lower than the set value, the controller will send a start command to the forward and reverse motor 2. After receiving the command, the forward and reverse motor 2 starts to work and drives the first gear 4 fixedly connected to its output end to rotate. The rotation of the first gear 4 will drive the second gear 5 meshing with it to rotate in the opposite direction. This gear transmission method ensures that the two threaded rods can rotate synchronously but in opposite directions. Since the thread rotation direction of the first threaded hole 12 is left-handed, the first threaded rod 13 will drive the first wet curtain plate 3 connected to it to move downward when it rotates; and the thread rotation direction of the second threaded hole 15 is right-handed, and the second threaded rod 16 will drive the second wet curtain plate 6 connected to it to move downward when it rotates. This design allows the two wet curtain plates to rise and fall at the same time without interfering with each other. As the first threaded rod and the second threaded rod continue to rotate, the first wet curtain plate 3 and the second wet curtain plate 6 are immersed in the water purification box 11 and the disinfection box 14 respectively to absorb moisture and disinfectant. When the preset position is reached or the humidity reaches the standard, the controller will send an instruction to reverse the forward and reverse motor 2, thereby driving the wet curtain plate to rise. In the process of the wet curtain plate descending and being immersed in the liquid, the humidifier can start its humidification and disinfection work, and discharge the humidified and disinfected air into the environment. Through the cooperation of gear transmission and threaded rods, the synchronous lifting and lowering of the first wet curtain plate 3 and the second wet curtain plate 6 are realized, ensuring the synchronous humidification and disinfection process. When it is necessary to add disinfectant to the humidifier or replace the disinfectant, the user can open the switch door 10 to directly contact the disinfection box 14. In this way, the disinfection box 14 can be easily maintained and managed to ensure that the disinfection effect of the humidifier is always kept in the best state. The moisture-proof coating can effectively isolate the humid air in the environment and prevent moisture from directly contacting the metal parts of the motor. In this way, the motor can be prevented from rusting or short-circuiting due to moisture, thereby extending the service life of the motor. Stainless steel has extremely high strength and hardness, and can withstand large torque and tension, ensuring that the first threaded rod can stably and reliably drive the wet curtain plate to move up and down during the operation of the humidifier. Stainless steel has excellent corrosion resistance, especially in a humid environment, and is not easy to rust or corrode. This feature allows the second threaded rod to maintain its original mechanical properties and appearance quality even when it is in contact with water for a long time, thereby extending the service life of the humidifier.

[0035] Through the threaded connection, the lifting height and speed of the wet curtain can be accurately controlled.

[0036] The above embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work all fall within the scope of protection of the utility model.
