DETAILED DESCRIPTION

[0027] The following is combined with Figure 1 This application is described in further detail.

[0028] The present application embodiment discloses a wireless liquid level alarm device based on lora networking. Figure 1 A wireless liquid level alarm device based on lora networking includes a first main control module 1, a liquid level detection module 2, a first wireless transmission module 3, a second wireless transmission module 4, a second main control module 5 and an alarm module 6. The liquid level detection module 2 and the first wireless transmission module 3 are both electrically connected to the first main control module 1, the second wireless transmission module 4 and the alarm module 6 are both electrically connected to the second main control module 5, the first wireless transmission module 3 and the second wireless transmission module 4 are wirelessly connected, and the liquid level detection module 2 is arranged in a medicine liquid cylinder.

[0029] The liquid medicine cylinder is a device for containing liquid medicine, which is arranged on a commercial washing machine or a dishwasher. Both the first wireless transmission module 3 and the second wireless transmission module 4 can be lora modules. In this embodiment, a commercial washing machine is used as an example for description.

[0030] The liquid level detection module 2 detects the height of the liquid in the liquid medicine cylinder and then the liquid level detection module 2 outputs a first electrical signal. After receiving the first electrical signal, the first main control module 1 controls the first wireless transmission module 3 to send the first electrical signal. The second wireless transmission module 4 receives the first electrical signal and transmits the first electrical signal to the first main control module 1. The first main control module 1 converts the first electrical signal into a liquid level height value after receiving it, and then determines whether the liquid level height value is less than a threshold value, and the threshold value is a preset value. If the liquid level height value is less than the threshold value, the second main control module 5 outputs a control electrical signal to the alarm module 6 to enable the alarm module 6 and make the alarm module 6 work, thereby playing a role in prompting the staff, and using the first wireless transmission module 3 and the second wireless transmission module 4, wireless transmission can be realized, the main control is far away from the commercial washing machine, reducing wired connections, and reducing the possibility of complex and chaotic lines.

[0031] A wireless liquid level alarm device based on lora networking also includes a control switch 7 and a power supply module 8. The first connection end of the control switch 7 is electrically connected to the alarm module 6, and the second connection end of the control switch 7 is electrically connected to the power supply module 8. When the corresponding commercial washing machine stops using and no liquid medicine is added to the liquid medicine cylinder, the corresponding alarm module 6 will continue to work. In order to avoid this situation, a control switch 7 is set, and the staff can disconnect the control switch 7 so that the power supply module 8 cannot supply power to the alarm module 6. At this time, even if the second main control module 5 sends a control electrical signal to the alarm module 6, the alarm module 6 will not work because it is not powered.

[0032] The alarm module 6 includes a voice alarm submodule and a light alarm submodule, and both the voice alarm submodule and the light alarm submodule are electrically connected to the second main control module 5. When it is determined that the liquid level height value is less than the threshold value, the second main control module 5 outputs a control electrical signal, and both the voice alarm submodule and the light alarm submodule are enabled, that is, both are working. It can serve as a reminder to the staff, and the two ways of reminder reduce the possibility that the staff fail to find the reminder.

[0033] The first main control module 1 is electrically connected to the storage module 9. After receiving the first electrical signal, the first main control module 1 converts the liquid level value and stores the liquid level value in the storage module 9. The storage module 9 is used to store data, so that the staff can retrieve the historical situation and perform historical data analysis.

[0034] The second main control module 5 is electrically connected to the display module 10. After receiving the first electrical signal, the second main control module 5 converts it into a liquid level value, and then the second main control module 5 controls the display module 10 to display the liquid level value. Although the alarm module 6 is controlled to alarm, the staff cannot know how much residual liquid is left. Therefore, the second main control module 5 controls the display module 10 to display the liquid level value, so that the staff can check the liquid level in real time, which improves convenience.

[0035] The second main control module 5 is electrically connected to a Bluetooth module 11. When the staff is performing maintenance or inspection at the commercial washing machine, they can use the terminal device to connect to the Bluetooth module 11. The second main control module 5 can transmit data to the terminal device using the Bluetooth module 11, which is convenient for the staff to check and improves convenience.

[0036] The first main control module 1 is also electrically connected to an input pump 12, the input end of the input pump 12 is used to communicate with the medicine liquid storage device, the output end of the input pump 12 is connected to a solenoid valve 13, the other end of the solenoid valve 13 is used to communicate with the medicine liquid cylinder, and the control end of the solenoid valve 13 is electrically connected to the first main control module 1.

[0037] When the liquid level height value is determined to be less than the threshold value, it is determined that the amount of medicine liquid in the medicine liquid cylinder is small and medicine liquid needs to be added to the medicine liquid cylinder. At this time, the first main control module 1 controls the solenoid valve 13 to open, and at the same time, the first main control module 1 controls the input pump 12 to work, and the medicine liquid in the medicine liquid storage device is extracted and transported to the medicine liquid cylinder. The input pump 12 and the solenoid valve 13 are set to realize the automatic addition of medicine liquid controlled by the first main control module 1, thereby improving the degree of automation, reducing manual participation, and reducing labor costs.

[0038] And because the liquid level detection module 2 can detect the height of the liquid medicine in the liquid medicine cylinder in real time, the first main control module 1 determines in real time whether the liquid medicine height value is greater than the upper limit value. When it is greater than the upper limit value, the first main control module 1 controls the input pump 12 to stop working and controls the solenoid valve 13 to close.

[0039] The implementation principle of the wireless liquid level alarm device based on lora networking in the embodiment of the present application is as follows: the liquid level detection module 2 detects the height of the liquid in the liquid medicine cylinder in real time and transmits an electrical signal to the first main control module 1. The first main control module 1 transmits the electrical signal to the second wireless transmission module 4 through the first wireless transmission module 3. The second wireless transmission module 4 receives the electrical signal and transmits it to the second main control module 5. The second main control module 5 converts the liquid level value and then determines whether the liquid level value is less than the threshold. If it is less than the threshold, the second main control module 5 controls the alarm module 6 to work, thereby providing a reminder to the staff. In addition, the use of wireless transmission can reduce the connection of wires and reduce the possibility of confusion on site.

[0040] Then, after determining that the liquid level value is less than the threshold value, the first main control module 1 controls the solenoid valve 13 to open, and controls the input pump 12 to work, so as to extract the liquid medicine from the liquid medicine storage device and transport it to the liquid medicine cylinder, so as to achieve the purpose of automatically adding liquid medicine. And after the liquid medicine height value is greater than the upper limit value, the first main control module 1 controls the input pump 12 to stop working, and controls the solenoid valve 13 to close.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
