Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-5, a device for automatically sensing disinfection solution comprises a disinfection solution bottle 1 and a disinfection solution bottle mounting rack 2, wherein one end of the disinfection solution bottle mounting rack 2 is mounted on a wall 8, the other end of the disinfection solution bottle mounting rack 2 is mounted with the disinfection solution bottle 1, a liquid level sensor 4 which is opposite to the left and the right is arranged at the inner side of the lower part of the disinfection solution bottle 1, an infrared reflection switch 3, a controller 7 and a liquid outlet pipe 6 are arranged at the outer side of the bottom of the disinfection solution bottle 1, and the liquid outlet pipe 6 is connected with an electromagnetic valve 9 arranged; the controller 7 comprises a microprocessor 71, and a power module 72, a voice module 73 and a relay driving module 74 which are electrically connected with the microprocessor 71, wherein the microprocessor 71 is also electrically connected with the infrared reflection switch 3 and the liquid level sensor 4, the output end of the relay driving module 74 is connected with the electromagnetic valve 9, and the power module 72 is also electrically connected with the electromagnetic valve 9.

As shown in fig. 2, the mounting frame 2 includes a fixed frame body 25 and a movable frame body 26, the rear end of the fixed frame body 25 is T-shaped, the front end of the fixed frame body 25 is arc-shaped, the movable frame body 26 is arc-shaped matched with the front end of the fixed frame body 25, the two ends of the arc-shaped part of the front end of the fixed frame body 25 are provided with a first mounting hole 21 and a second mounting hole 22, the two ends of the arc-shaped part of the movable frame body 26 are also provided with mounting holes, and the two ends of the arc-shaped parts of the fixed frame body 25 and the movable frame body 26 are mounted together through a first screw; two ends of a cross bar of the T-shaped part at the rear end of the fixed frame body 25 are respectively installed on the wall body 8 through third screws 27. Because the two ends of the arc-shaped parts of the fixed frame body 25 and the movable frame body 26 are installed together through screws, the screws can be screwed down to clamp the bottles of different specifications between the arc-shaped parts of the fixed frame body 25 and the movable frame body 26.

As shown in fig. 5, the relay driving module 74 includes a transistor Q1 and a relay K, a base of the transistor Q1 is connected with one end of a resistor R3, the other end of the resistor R3 is connected with one end of a resistor R2 and a control end of the microprocessor 71, the other end of the resistor R2 is connected with a power supply terminal VCC and one end of a resistor R1, the other end of the resistor R1 is connected with a negative electrode of a diode D1 and one end of an input end of the relay K, an anode of a diode D1 and the other end of the input end of the relay K are connected with a collector of the transistor Q1, an emitter of the transistor Q1. When the microprocessor 71 outputs high level to the base of the triode Q1, the collector and the emitter of the triode Q1 are conducted, the relay is electrified, the terminal of the output end of the relay is closed, and the electromagnetic valve is electrified.

The microprocessor 71 is a single-chip processor. Can be a 51-series single chip microcomputer or an MSP 430-series single chip microcomputer on the market.

As shown in fig. 1, the infrared reflective switch 3 is model TX 05D. When the TX05D is powered on, modulated infrared rays are emitted forward from an infrared emission tube in the module, once a person stretches his hand under the infrared reflection switch 3 and enters an effective range, part of the infrared rays are reflected back, received by a photosensitive receiving tube arranged in the same row as the emission tube and converted into electric signals with the same frequency, processed by a circuit in the module, compared and processed, and then high-level signals are given out at an output end and detected by a single chip microcomputer.

The level sensor 4 is an opto-electronic level sensor comprising a light emitting diode and a receiver electrically connected to the microprocessor 71. As shown in fig. 1, the photoelectric liquid level sensor is a novel contact type point liquid level measurement and control device developed by using the principle that light is reflected and refracted at interfaces of two different media. The working principle is that the product internally comprises a near infrared light emitting diode and a photosensitive receiver. The light emitted by the light emitting diodes is directed into a lens on top of the sensor. When the liquid immerses the lens of the photoelectric liquid level switch, light is refracted into the liquid, so that the receiver cannot receive light or can receive light only in a small amount. By sensing this change in condition, the receiver can drive an internal electrical switch. If there is no liquid, the light emitted by the light emitting diode is reflected directly from the lens back to the receiver. By the difference of whether liquid exists or not, the microprocessor 71 can drive the voice module 73 to prompt an alarm when no liquid exists, and liquid adding is required.

The power module 72 is a lithium battery, a 5V battery, one way for supplying a single chip microcomputer and one way for supplying a magnetic valve.

The top of the disinfectant bottle 1 is provided with a liquid feeding cover 11, and the liquid feeding cover 11 is installed on a liquid feeding port at the top in a threaded manner, so that the disinfectant bottle plays a role in protecting from external pollution.

The liquid level sensor 4 is externally wrapped with a transparent protective cover 5 which is integrally designed with the disinfectant bottle 1, so that the short circuit caused by the contact of the liquid level sensor with the disinfectant can be avoided.

The working principle is as follows:

when the bottle opener is used, two ends of the arc-shaped parts of the fixed frame body 25 and the movable frame body 26 are installed together through screws, and the screws can be screwed down to clamp the bottles between the arc-shaped parts of the fixed frame body 25 and the movable frame body 26 aiming at bottles with different specifications. When hands need to be disinfected, hands are placed at the lower part of the liquid outlet pipe 6, the infrared reflection switch 3 is blocked, the microprocessor 71 senses the infrared reflection switch 3, the high-level pulse signal is sent to the relay driving module 74 by the microprocessor 71, the relay driving module 74 drives the electromagnetic valve 9 to act, the liquid outlet pipe 6 is communicated with the interior of the disinfectant bottle 1 after the electromagnetic valve 9 is opened, and disinfectant in the disinfectant bottle 1 flows out of the hands at the lower part of the liquid outlet pipe 6 due to gravity. After the high-level pulse signal output by the microprocessor 71 disappears, the electromagnetic valve 9 is closed again. When the disinfectant in the disinfectant bottle 1 is nearly used up, the microprocessor 71 can drive the voice module 73 to prompt an alarm when no liquid exists and requires liquid feeding by detecting through the liquid level sensor 4.
