Abstract
Description
Technical Field
[0001] The utility model relates to an indoor humidity regulating device, in particular to a humidifier with a photoelectric detection component. Background Art
[0002] A humidifier is a very common indoor humidity regulating device, which is widely used in indoor humidity regulating occasions. However, in the existing humidifier, since its water storage component is usually in a relatively closed space, the user cannot accurately know the amount of water stored in the humidifier.
[0003] Chinese patent document CN212204979U discloses a humidifier water tank with a gravity sensor and a humidifier used therein, which utilizes the collection end of the gravity sensor to collide with the bottom of the water tank body, so that the gravity generated by the weight of the water in the water tank body can be collected by the gravity sensor and transmitted to the control module, and the control module determines the amount of water in the water tank according to the current gravity collection value. Although this structure solves the drawback that the amount of water in the water tank cannot be accurately monitored to a certain extent, it still has two technical defects. First, in the humidifier of this structure, objects cannot be placed above the water tank, otherwise it will cause the gravity sensor to make mistakes in judging the amount of water in the water tank, and it will still default to normal operation when the water tank is short of water, thereby burning the transducer component of the humidifier. Second, existing humidifiers generally use tap water as the humidifying liquid, and the scale in the water will continue to accumulate on the outer edge of the water tank and the transducer component when the humidifier works for a long time. This accumulation phenomenon will cause the weight of the water tank to increase continuously, thereby causing the accuracy of the gravity sensor in detecting the amount of water to decrease continuously. In addition to hindering the normal operation of the humidifier, it will also cause the transducer component of the humidifier to burn out. Summary of the invention
[0004] The utility model aims to overcome the deficiencies of the prior art and provide a humidifier with a photoelectric detection component which has good stability and high reliability.
[0005] The purpose of the utility model is achieved as follows: A humidifier with a photoelectric detection component mainly includes a control component, a water storage tank and an atomization component. The control component and the water storage tank are connected together in sequence from top to bottom, and the atomization component is arranged on the control component and can extend into the water storage tank. The atomization component is connected to the bottom of the control component and can rotate around the axis on the control component. There is also a photoelectric detection component between the atomization component and the control component, and the photoelectric detection component can rotate synchronously with the atomization component to transmit the detection signal to the control component in real time when the water level of the water storage tank changes.
[0006] By optimizing the humidifier with the photoelectric detection component, the atomization component includes a rotating shaft, a hollow connecting rod and an ultrasonic transducer. The rotating shaft and the ultrasonic transducer are arranged at both ends of the hollow connecting rod. The ultrasonic transducer is located inside the water storage tank and is electrically connected to the control component through the hollow part of the connecting rod to ensure that the circuit is completely isolated from the water in the water storage tank.
[0007] By further refining the humidifier with the photoelectric detection component, the photoelectric detection component includes a sensing part and a rotating part. The sensing part is arranged on the control component, and the rotating part is arranged on the rotating shaft. The rotation amplitude of the atomizing component is detected by changing the positional relationship between the sensing part and the rotating part, so as to obtain the water level change result in the water storage tank.
[0008] By further refining the humidifier with a photoelectric detection component, the sensing part includes a seat, a power supply component and a sensing plate. The seat is fixed on the control component to position the sensing plate. The power supply component is also fixed on the control component and electrically connected to the control component to provide working power to the sensing plate. The sensing plate is fixed on the seat, electrically connected to the power supply component, and at least two sensing heads are evenly distributed on the sensing plate along the radial direction of the rotating shaft.
[0009] By further refining the humidifier with the photoelectric detection component, the rotating part is mainly composed of at least two sensing sheets. The sensing sheets are distributed on the outer circumference of the rotating shaft, and the width of the sensing sheets increases in a direction away from the ultrasonic transducer sheet and corresponds to the position of the sensing head.
[0010] By optimizing the humidifier with the photoelectric detection component, the control component is also provided with a support seat, which can support the rotating shaft and enable the rotating shaft to rotate on the support seat.
[0011] By optimizing the humidifier with the photoelectric detection component, power connection sockets are respectively provided on the power supply component and the control component to realize the power supply of the control component to the power supply component and the sensor board.
[0012] The beneficial effects of the humidifier with photoelectric detection components of the utility model are:
[0013] 1. The utility model adopts a photoelectric detection component separated from the water body, and detects the amount of water in the water tank by the rotation of the atomizing component when the water level changes. First, this structure can avoid the situation where the water level detection component comes into contact with the water body, completely eliminates the short circuit of the detection component due to incomplete sealing, and effectively ensures the stability and reliability of the detection component. Secondly, the rotation of the atomizing component is used for detection to avoid the influence of changes in water quality. Even if scale is generated, it will not affect the entire detection process, making the detection of the water level in the water tank more accurate.
[0014] 2. In the photoelectric detection assembly of the utility model, at least two sensor heads are evenly distributed on the sensor plate along the radial direction of the rotating shaft, and at least two sensor sheets correspond to the positions of the sensor heads, and the width of the sensor sheets increases successively in the direction away from the ultrasonic transducer sheet. This structure can realize photoelectric detection of the sensor head by allowing the sensor sheets to pass through the sensor heads in sequence when the rotating part rotates due to the change in water level. The change in the width of the sensor sheet can produce an incompletely synchronous sensing on-off effect on the sensor head, thereby increasing the number of combinations of on-off changes of the sensor head, so that the amount of water in the water tank changes from more to less until it enters a water shortage state, and the sensor head can perform accurate sensing, thereby improving the accuracy of the photoelectric detection assembly.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The following embodiments are one or several examples that can realize the new technical solutions of the utility model, obtain corresponding technical effects, and solve corresponding technical problems, and do not limit the protection scope of the utility model to only within the scope of the following embodiments.
[0025] according to Figures 1 to 5 As shown, the humidifier with a photoelectric detection component of the utility model is mainly composed of a water tank 2, a control component 1, an atomization component and a photoelectric detection component. Among them, the control component 1 and the water tank 2 are connected together in sequence from top to bottom, and the two can be separated independently, so that the user can add water to the water tank 2. The water tank 2 is provided with a mist outlet 21, which is located at the upper part of the water tank 2, specifically, at the junction of the water tank 2 and the control component 1. One function of the mist outlet 21 is to facilitate the output of the water mist in the water tank 2 to the outside world, and the other function is to facilitate the user to separate the water tank 2 and the control component 1. The atomization component is arranged on the control component 1, specifically, at the bottom of the control component 1, and extends into the water tank 2, so that when the atomization component is working, water mist is generated in the water tank 2 and output to the outside world through the mist outlet 21. The atomizing assembly and the control assembly 1 are rotatably connected, that is, the atomizing assembly can rotate at the bottom of the control assembly 1, so that when the water level in the water tank 2 changes, the atomizing assembly can rotate under the action of a fixed buoyancy and always be at a suitable depth below the water surface to ensure its normal operation. The photoelectric detection assembly is arranged in the control assembly 1, which is located between the control assembly 1 and the atomizing assembly, and can rotate synchronously with the atomizing assembly to accurately detect the water level in the water tank 2. For the control assembly 1 in the utility model, those skilled in the art can refer to the records in the Chinese patent document CN201589370U, and only need to select the control module according to the use requirements. Those skilled in the art can also realize the control function of the humidifier according to the commercially available control type single chip microcomputer and by editing the program. Of course, the control assembly 1 needs to reserve the power supply, signal and other interfaces of the photoelectric detection assembly, and add the corresponding functions in the control program, which will not be described in detail here.
[0026] In one embodiment of the utility model, the atomizing assembly includes a rotating shaft 31, a connecting rod 32 and an ultrasonic transducer 33 connected in sequence. The rotating shaft 31 is located in the control assembly 1 and is fixed together with the connecting rod 32, so that when the water level in the water tank 2 changes, the rotating shaft 31 can drive the connecting rod 32 and the ultrasonic transducer 33 to rotate. The connecting rod 32 is a hollow rod body, and the hollow part is used to accommodate the power line between the ultrasonic transducer 33 and the control assembly 1. The ultrasonic transducer 33 is located in the water tank 2 and is electrically connected to the control assembly 1 through the connecting rod 32. In this embodiment, a sealing seat 34 is also provided outside the ultrasonic transducer 33, and the sealing seat 34 is used to accommodate and fix the ultrasonic transducer 33, so that the working end of the ultrasonic transducer 33 contacts the water, and the power connection end of the ultrasonic transducer 33 contacts the water to avoid short circuit and burning, and it provides a fixed buoyancy for the ultrasonic transducer 33 in the water, so that it is always suspended at a fixed depth below the water surface, ensuring the stability of the ultrasonic transducer 33. Regarding the working principle of the ultrasonic transducer 33 , those skilled in the art may refer to the description in Chinese patent document CN204597926U, or select a commercially available ultrasonic transducer 33 of matching power and size, which will not be described in detail here.
[0027] In another embodiment of the present invention, the photoelectric detection component can adopt a combined structure of a sensing part and a rotating part, and the sensing part is arranged on the control component 1, which can detect the position of the rotating part. The rotating part is fixed on the rotating shaft 31, and it rotates synchronously with the rotating shaft 31 when the water level of the water tank 2 changes, so as to transmit the water level state of the water tank 2 to the control component 1 through the relative position change of the rotating part and the sensing part.
[0028] In another embodiment of the utility model, the sensing part includes a seat 41, a power supply component 42, a sensing plate 43 and a sensing head 44. The seat 41 is fixedly arranged on the control assembly 1 to form a positioning structure between the sensing plate 43 and the rotating shaft 31. The power supply component 42 is located in the control assembly 1 and is electrically connected to the control assembly 1 to meet the power demand of the sensing plate 43 when it is working. For the power supply component 42 of the utility model, those skilled in the art can refer to the records in the Chinese patent document CN102624261A, or use a commercially available control point circuit power supply board. The sensing plate 43 is fixed on the seat 41 and is electrically connected to the power supply component 42. The sensing head 44 is fixed on the sensing plate 43, and is evenly distributed along the radial direction of the rotating shaft 31. There are at least two sensing heads 44 to produce a combined sensing effect on the rotating part when the rotating shaft 31 rotates. In this embodiment, in order to make the water level sensing information more accurate, there are three sensing heads 44 on the sensing plate 43. For the working principle and process of the induction head 44 , those skilled in the art may refer to the description in Chinese patent document CN104283543A, or use a commercially available through-beam photoelectric detection switch.
[0029] In another embodiment of the utility model, the rotating part is composed of at least two sensing sheets 51. The sensing sheet 51 is located at the periphery of the rotating shaft 31 and is fixed to the outer edge of the rotating shaft 31 through the connecting sheet 52. The sensing sheet 51 corresponds to the position of the sensing head 44. Specifically, when the rotating shaft 31 rotates, the sensing sheet 51 can continuously pass through the detection area of the sensing head 44 through circular motion. At the same time, the width of the sensing sheet 51 is set in a gradual manner. Specifically, its width increases in sequence along the direction away from the ultrasonic transducer sheet 33. In this embodiment, in order to make the water level sensing information more accurate, there are three sensing sheets 51 on the connecting sheet 52.
[0030] In another embodiment of the utility model, the control assembly 1 further has a support seat 11. The support seat 11 can be integrally formed on the control assembly 1, and supports the rotating shaft 31 to ensure that the rotating shaft 31 can rotate smoothly when the water level changes. In addition, a sealing plate 13 is also provided below the control assembly 1, and the sealing plate 13 effectively blocks the space between the control assembly 1 and the water tank 2, preventing the water mist in the water tank 2 from entering the control assembly 1.
[0031] In another embodiment of the utility model, a power connection socket 12 is provided on both the power supply component 42 and the control component 1. The positions of the power connection sockets 12 correspond to each other, and are used for power supply and transmission of electrical signals in electrical connection. In fact, a power connection socket 12 is also provided on the induction board 43, and its position corresponds to the power connection socket 12 on the power supply component 42.
[0032] See also Figure 6 , Figure 7 and Figure 8 When the water level in the water tank 2 is high, the sensing piece 51 with the largest width completely blocks the sensing head 44, and the other two sensing heads 44 are in a conducting state. When the water level in the water tank 2 drops, the sealing seat 34 drives the connecting rod 32 and the rotating shaft 31 to rotate under the action of the fixed buoyancy. At this time, the sensing piece 51 with the middle width gradually blocks the sensing head 44, while the sensing piece 51 with the largest width has not yet separated from the sensing head 44, so the sensing head 44 at the bottom is in a conducting state. When the water level in the water tank 2 drops to a water shortage state, the rotating shaft 31 continues to rotate so that the sensing pieces with the largest width and the sensing pieces with the middle width are separated from the sensing heads 44, and only the sensing piece 51 with the smallest width blocks the sensing head 44 at the bottom, and the two sensing heads 44 at the top are in a conducting state. The on-off state of the sensing head 44 is transmitted to the control component 1 through the power connection seat 12 and the power supply component, and the control component 1 issues a water shortage state prompt.
