Description

Technical Field

[0001] This invention relates to the field of humidifier technology, and in particular to an automatic detection device and detection method for humidifiers. Background Technology

[0002] Humidifiers, as common household appliances, function to increase the humidity in a room. They work by atomizing water into ultrafine particles, which are then diffused into the air, thus moistening the air and improving comfort. However, when using a humidifier, the water level in the tank is often overlooked. Continuing to operate the humidifier after the water tank is depleted can damage it.

[0003] Chinese Patent Application Publication No. CN 103292438 A, Publication Date: September 11, 2013, discloses a water level monitoring humidifier, including a body, a heater, a humidity sensor switch, a hygrometer, and a water level monitor. The heater and water level monitor are fixed inside the lower part of the body, while the humidity sensor switch and hygrometer are located outside the body. One end of the body has an opening. Its advantages are that by measuring and displaying the ambient humidity, and by using the sensor switch to control the humidifier based on different humidity levels, it achieves intelligent humidification, avoiding blind humidity adjustments; and by using the water level monitor to control the humidifier based on water level changes, it protects the humidifier. This solution uses a water level monitor to monitor the water level and a humidity sensor to monitor the humidity to control the humidifier's on / off state. However, this solution cannot achieve real-time monitoring of the water level during use, which has certain limitations.

[0004] Therefore, it is necessary to design an automatic detection device and detection method for humidifiers to monitor the water level in the tank in real time during use and ensure safe use. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of the existing technology in the detection of water tank level, and provides an automatic detection device and detection method for humidifiers that can monitor water tank volume in real time and ensure safe use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic detection device for a humidifier, comprising a humidifier housing, an atomizing tube disposed in the middle of the humidifier housing, water tanks communicating with the atomizing tube on both sides of the atomizing tube, the water tanks being connected to the humidifier housing, an installation plate being connected inside the humidifier housing, a signal generator being disposed below the installation plate, a signal receiver capable of floating on the water surface being connected inside the water tank, a control processing unit being connected above the installation plate, the signal generator and the signal receiver being electrically connected to the control processing unit, and an ultrasonic atomizer capable of floating on the water surface being disposed inside the atomizing tube, the ultrasonic atomizer being slidably connected to the atomizing tube.

[0007] A misting tube is vertically placed in the middle of the humidifier's outer casing. Water tanks are located on both sides of the misting tube, connected to both the tube and the humidifier's outer casing. An ultrasonic atomizer, floating on the water surface, is installed inside the misting tube. This atomizer atomizes the water within the tube using ultrasonic waves, achieving the humidification effect. An installation plate is located inside the humidifier's outer casing, positioned above the misting tube. A signal generator is located below the installation plate, and a floating signal receiver is located inside the water tank. The signal generator and receiver are on the same vertical axis. A control processing unit is connected above the installation plate, electrically connected to both the signal generator and receiver. The signal generator transmits signals to the receiver, which then transmits the information to the control processing unit. The control processing unit processes the feedback signals to determine the water level changes within the tank. Because the atomizing tube is connected to the water tank, the water level in the atomizing tube is the same as the water level in the water tank. Therefore, when the water level in the water tank is at the alarm line, the ultrasonic atomizer in the atomizing tube is also at the critical position. At this time, the water level in the water tank is monitored and detected in real time by the signal generator and the signal receiver, so as to monitor the water level change and monitor whether the ultrasonic atomizer of the humidifier is in a safe operating environment, thereby ensuring the safe use of the humidifier.

[0008] Preferably, the atomizing tube is positioned in the middle of the humidifier's outer casing. A guide groove is provided on the inner wall of the atomizing tube. A float plate, circular in shape, is connected to the bottom of the ultrasonic atomizer. Two guide blocks are provided on the side wall of the float plate, and these guide blocks are slidably connected to the guide groove. The float plate is circular, the inner wall of the atomizing tube has a guide groove, and two guide blocks are arranged opposite each other within the guide groove. The ultrasonic atomizer is positioned above and connected to the float plate, allowing the float plate to slide vertically along the guide groove. This allows the ultrasonic atomizer to move up and down with the water level, ensuring its stability, the accuracy of the detected water level, and the safe use of the humidifier.

[0009] Preferably, a spring is connected to the bottom of the atomizing tube, and the spring is connected to the float plate. The spring provides a pulling force to pull the float plate down, ensuring that the float plate is in contact with the water inside the atomizing tube, and at the same time ensuring that the ultrasonic atomizer is in contact with the water, ensuring that the ultrasonic atomizer can work normally, and ensuring the normal operation of the humidifier's humidification function and the safe use of the humidifier.

[0010] Preferably, the bottom sidewall of the atomizing tube is connected to a water inlet pipe, the end of which is sealed. The sidewall of the water inlet pipe has several water inlet holes. The bottom sidewall of the water tank is connected to a water guide pipe, the end of which is elastically connected to a sealing plug. The water inlet pipe and the water guide pipe are sleeved together, and the water inlet pipe corresponds to the sealing plug. A water inlet pipe is located at the bottom of the atomizing tube, and a water guide pipe is located at the bottom of the water tank. The water inlet pipe and the water guide pipe are sleeved together, and the water inlet pipe is inserted into the water guide pipe. The water inlet pipe is a pipe with a sealed end, and several water inlet holes are provided on the sidewall of its end. After the water inlet pipe is inserted into the water guide pipe, the position of the water inlet holes exceeds the end face of the water guide pipe, allowing water from the water tank to enter the atomizing tube through the water inlet pipe, making the water level in the atomizing tube level with the water level in the water tank. When checking the water level, the water level in the water tank is... The water level detection function can detect the water level inside the atomizing tube. Real-time detection of the water level inside the atomizing tube can protect the ultrasonic atomizer. A sealing block is installed at the end of the water guide tube placed in the water tank. The sealing block is elastically connected to the water guide tube. When the water inlet tube is inserted into the water guide tube, the water inlet tube pushes out the sealing block, so that the water inlet hole exceeds the end face of the water guide tube, allowing water to enter. When the water tank needs to be filled, the sealing block blocks the water guide tube to prevent water leakage and ensure the functionality of the humidifier.

[0011] Preferably, the sidewall of the sealing block is connected to an elastic strap, which is connected to the sidewall of the water pipe. The sidewall of the sealing block is provided with rubber protrusions, which correspond to the inner diameter of the water pipe. The elastic strap connects the sealing block and the water pipe, ensuring that the sealing block can block the water pipe when water is added to the tank. The rubber protrusions on the sidewall of the sealing block are hemispherical, allowing for better sealing of the water pipe and ensuring a tight seal, thus guaranteeing the normal operation of the humidifier.

[0012] Preferably, a float is connected to the bottom of the signal receiver, and a traction rope is connected below the float. The traction rope is connected to the bottom of the water tank and positioned directly below the signal generator. The float allows the signal receiver to move simultaneously with the rise and fall of the water level in the tank. The traction rope below the float, being an elastic rope, ensures that the float keeps the signal receiver positioned below the signal generator. This guarantees that the signal receiver and signal generator can obtain corresponding data as the distance between them changes, ensuring the accuracy of real-time water level monitoring and the safe use of the humidifier.

[0013] Preferably, a display screen is connected to the upper side wall of the humidifier housing, and the display screen is electrically connected to the control processing unit. The display screen is located on the upper part of the humidifier housing and forms a circuit with the control processing unit via electrical connection. The display screen shows the water level value and the position of the water level warning line in the water tank. After the control processing unit processes the signals transmitted from the signal generator and signal receiver, the data is displayed on the screen, serving as a prompt and enabling real-time detection of water level changes to ensure safe use of the humidifier.

[0014] Preferably, an audible alarm is connected to the upper side wall of the humidifier casing, and the audible alarm is electrically connected to the control processing unit. The audible alarm is mounted on the humidifier casing, and the electrical connection between the audible alarm and the control processing unit forms a circuit. When the water level in the water tank reaches the warning line, the control processing unit receives and processes the signal transmitted from the signal generator and signal receiver, and transmits the warning signal to the audible alarm. The audible alarm then sounds, indicating that the humidifier needs water, thus monitoring the water level and ensuring the safe use of the humidifier.

[0015] Preferably, the mounting plate has a clearance hole in the middle, which communicates with the atomizing tube. A guide fan is connected to the inner wall of the clearance hole, and a tapered diffuser is connected to the end of the clearance hole. The guide fan, installed inside the clearance hole, rotates to guide the water vapor atomized by the ultrasonic atomizer in the atomizing tube out of the humidifier, achieving the humidification effect. The diffuser connection at the end of the clearance hole facilitates the outward diffusion of the atomized water vapor, preventing water vapor accumulation in the atomizing tube and ensuring normal operation of the humidifier.

[0016] A detection method for an automatic detection device of a humidifier, comprising the following steps.

[0017] S1. The signal generator and signal receiver change due to the change in the water level in the water tank, and the control processing unit collects and processes the changed signal.

[0018] S2. The signal processed in step S1 is transmitted to the display screen, where it is converted into water level data and displayed on the screen.

[0019] S3. When the water level in the tank reaches the warning line, the control processing unit processes the collected signals and converts them into an alarm signal, which is then transmitted to the sound alarm to emit an alarm sound.

[0020] The signal generator emits a signal that is received by a signal receiver. Changes in the water level within the tank alter the distance between the receiver and the generator. The control processing unit collects and processes both signals, then transmits the processed information to the display screen. The screen shows the water level and the warning line position. During use, users can add water or shut down the humidifier when the warning line is reached, based on the displayed data. Simultaneously, when the water level reaches the warning line, the control processing unit converts the collected water level signal into an alarm signal, which is transmitted to the audible alarm. The alarm sounds, indicating that the humidifier's water level is at the warning line and requiring the addition of water or shutdown to ensure safe operation.

[0021] The beneficial effects of this invention are as follows: the atomizing tube is connected to the water tank, the water level in the water tank is the same as that in the atomizing tube, an ultrasonic atomizer that can float on the water surface is installed in the atomizing tube, and a signal generator and a signal receiver are installed in the water tank for real-time monitoring of the water level in the atomizing tube. When the water level reaches the warning line, the control processing unit converts the signals collected from the signal generator and the signal receiver into a display signal and an audible warning signal. The display screen shows the real-time changes in the water level, and the audible alarm sounds an alarm to ensure the safe use of the humidifier. Attached Figure Description

[0039] A float 60 is connected to the bottom of the signal receiver 6, and a traction rope 61 is connected below the float 60. The traction rope 61 is connected to the bottom of the water tank 3 and is positioned directly below the signal generator 5.

[0040] A display screen 10 is connected to the upper side wall of the humidifier housing 1, and the display screen 10 is electrically connected to the control processing unit 7.

[0041] A sound alarm 11 is connected to the upper side wall of the humidifier housing 1, and the sound alarm 11 is electrically connected to the control processing unit 7.

[0043] A detection method for an automatic detection device of a humidifier, comprising the following steps.

[0044] S1. Due to the change in the water level in the water tank 3, the signals of the signal generator 5 and the signal receiver 6 change, and the control processing unit 7 collects and processes the changed signals.

[0045] S2. The signal processed in step S1 is transmitted to the display screen 10, where it is converted into water level data and displayed on the display screen 10.

[0046] S3. When the water level in the water tank 3 reaches the water filling value, the control processing unit 7 processes the collected signals and converts them into an alarm signal, which is then transmitted to the sound alarm 11 to emit an alarm sound.

[0047] The working principle of this invention is as follows: Figure 1-6As shown, a vertically placed atomizing tube 2 is installed inside the humidifier housing 1, positioned at the central axis of the housing 1. A water tank 3 is installed on the top of the housing 1, with a water guide pipe 30 at the bottom. A water inlet pipe 22 is installed at the bottom of the atomizing tube 2, with its end sealed. Several water inlet holes 23 are provided on the side wall of the end of the water inlet pipe 22. When the water tank 3 and the atomizing tube 2 are connected, the water guide pipe 30 of the water tank 3 must be fitted onto the water inlet pipe 22 of the atomizing tube 2. The water inlet holes 23 should be positioned beyond the end face of the water guide pipe 30 during the fitting, so that water from the water tank 3 enters through the water inlet holes 23, passes through the water inlet pipe 22, and then enters the atomizing tube 2, thus connecting the atomizing tube 2 and the water tank 3. To prevent water leakage when the inlet pipe 22 and the outlet pipe 30 are connected, a sealing gasket is fitted onto the inlet pipe 22 to achieve a seal and prevent leakage. At the end of the outlet pipe 30, a sealing block 31 is provided. One side of the sealing block 31 has a rubber protrusion 33, which matches the inner diameter of the outlet pipe 30, ensuring a good seal and preventing leakage when the rubber protrusion 33 seals the outlet pipe 30. Meanwhile, elastic straps 32 are provided on both sides of the sealing block 31. The elastic straps 32 are connected to the side wall of the water guide pipe 30. When the water tank 3 is taken out to add water, the sealing block 31 blocks the water guide pipe 30 to prevent water leakage during water addition. When the water tank 3 is connected to the atomizing pipe 2, the water inlet pipe 22 is inserted into the water guide pipe 30, pushing the sealing block 31 outward so that the water inlet hole 23 extends beyond the water guide pipe 30, thereby connecting the water tank 3 and the atomizing pipe 2 and ensuring that the water levels in both are the same.

[0048] A guide groove 20 is provided on the inner wall of the atomizing tube 2. A float plate 80 that can float on the water surface is provided inside the atomizing tube 2. An ultrasonic atomizer 8 is connected above the float plate 80. A guide block 81 is provided on the side of the float plate 80. The guide block 81 is inserted into the guide groove 20, so that the float plate 80 can move stably in the vertical direction. A spring 21 is provided below the float plate 80. The spring 21 provides a downward pulling force to the float plate, so that the float plate 80 is in close contact with the water surface, while ensuring that the ultrasonic atomizer 8 is in close contact with the water, thus ensuring the atomization effect of the ultrasonic atomizer 8.

[0049] A float 60 is installed inside the water tank 3, and a signal receiver 6 is connected to the float 60. An mounting plate 4 is installed inside the humidifier housing 1, and a signal generator 5 is located below the mounting plate 4, positioned above the water tank 3. The signal generator 5 and the signal receiver 6 are on the same vertical axis. An elastic traction rope 61 is connected below the float 60, ensuring that the signal receiver 6 remains below the signal generator 5 regardless of changes in the water level in the water tank 3. The signal emitted by the signal generator 5 is received by the signal receiver 6. Simultaneously, a control processing unit 7 is electrically connected to both the signal generator 5 and the signal receiver 6. The signal received by the control processing unit 7 will differ depending on the water level. After processing by the control processing unit 7, the signal is converted into a display signal and an audible signal. A display screen and an audible alarm 11 are installed on the outer wall of the humidifier housing 1. The change in water level is processed by the control processing unit 7 and the resulting display signal is displayed on the display screen 10. When the water level reaches the water level warning line, an audible signal is transmitted to the audible alarm 11, which then sounds a buzzer to indicate that the humidifier needs to be refilled or turned off. This achieves real-time detection of the water level in the water tank 3 and ensures the safe use of the humidifier.

[0050] In Example 2, the mounting plate 4 inside the humidifier housing 1 is provided with a clearance hole 40, which is connected to the atomizing tube 2. A guide fan 41 is provided inside the clearance hole 40. The guide fan 41 consists of a rotating motor and fan blades. The guide fan 41 can quickly exhaust the water vapor obtained after atomization in the atomizing tube 2, preventing it from accumulating in the atomizing tube 2 and affecting the water level detection, thus ensuring the accuracy of water level detection and the safe use of the humidifier.

[0051] A tapered diffuser tube 42 is connected to the upper end of the clearance hole 40. The diffuser tube 42 can quickly discharge the atomized water vapor in the atomizing tube 2 and diffuse it into the air to humidify the air, prevent it from accumulating in the atomizing tube, affecting the water level detection, ensuring the accuracy of the water level detection, and ensuring the safe use of the humidifier.
