[0034] Figure 2 A working flowchart of the energy-saving cleaning equipment in the embodiment of the utility model.

[0035] Figure 3 Another structure diagram of the intelligent energy-saving cleaning equipment is provided in the embodiment of the utility model. Specific implementation

[0036] The technical content of the utility model will be explained in detail with the specific embodiments and the accompanying drawings.

[0037] As Figure 1 shown, the utility model discloses an intelligent energy-saving cleaning equipment, including liquid storage pump 1, pressure switch 2, pressurization control part 3 and cleaning part 4. Among them, liquid storage pump 1 is used to store cleaning liquid, and is connected with cleaning part 4, to be able to carry out cleaning operation through cleaning part 4. Pressure switch 2 is installed on liquid storage pump 1, is used to detect the water pressure inside liquid storage pump 1 in real time in the upper and lower changes of pressure threshold value, to output switch signal. Pressure switch 2 is electrically connected with pressure control part 3, and the switch signal of pressure switch 2 will be detected by pressure control part 3 and controls pressure output simultaneously, to realize energy-saving control further.

[0038] Specifically, in an embodiment of the utility model, liquid storage pump 1 is crankshaft high pressure pump head. The liquid inlet of the liquid storage pump 1 is communicated with the liquid inlet pipe 101, and the liquid outlet is communicated with the liquid outlet pipe 102. Correspondingly, the cleaning part 4 is connected to the end of the liquid outlet pipe 102 away from the liquid storage pump 1. Thus, the liquid can be sucked into the liquid storage pump 1 from the liquid supply part (for example, a water well) through the liquid inlet pipe 101, so that the liquid pressure in the liquid storage pump 1 is continuously increased. And the liquid can be pumped out of the liquid storage pump 1 through the liquid outlet pipe 102, and then sprayed through the cleaning part 4 to reduce the liquid pressure in the liquid storage pump. It can be understood that the selection of the crankshaft high pressure pump head in this embodiment is only a relatively optimal implementation manner, and can be adaptively selected according to the needs in other embodiments.

[0039] Pressure switch 2 is connected with liquid storage pump 1, and is used to detect the liquid pressure in liquid storage pump 1 in real time. When the liquid pressure is higher than the preset threshold value, the pressure switch 2 is in the open state. When the liquid pressure is not higher than the preset threshold value, the pressure switch 2 is in the closed state. It can be understood that when the pressure switch 2 is in the open state, it indicates that the liquid stored in the liquid storage pump 1 is sufficient and does not need to be pumped and pressurized. At this time, the liquid storage pump 1 is in standby state. When the cleaning part 4 starts cleaning operation, the liquid pressure in the liquid storage pump 1 will gradually decrease. Once the liquid pressure decreases below the preset threshold value, it indicates that the liquid stored in the liquid storage pump 1 is insufficient, and pumping and pressurizing is needed. At this time, the liquid storage pump 1 is in working state. Therefore, based on the setting of the pressure switch 2, the automatic detection of the pressure can be realized, thereby avoiding the energy waste caused by the continuous and uninterrupted work of the liquid storage pump 1.

[0040] The pressure control part 3 comprises a driving motor 31 and a motor controller 32. The driving motor 31 is connected with the liquid storage pump 1 and is used to drive the liquid storage pump 1 to suck liquid. In the embodiment, the driving motor 31 is a permanent magnet synchronous motor, and the motor controller 32 can realize frequency conversion control of the driving motor 31, so as to change the working frequency of the permanent magnet synchronous motor. One end of the motor controller 32 is connected with the pressure switch 2, and the other end is connected with the driving motor 31, so as to receive the current state of the pressure switch 2 and control the start and stop of the driving motor 31. Specifically, in the embodiment, when the pressure switch 2 is in the closed state, the motor controller 32 controls the driving motor 31 to start, and then drives the liquid storage pump 1 to suck liquid. Conversely, when the pressure switch 2 is in the open state, the motor controller 32 controls the driving motor 31 to stop, and then controls the liquid storage pump 1 to stop sucking liquid.

[0041] It can be understood that the motor controller 32 in the embodiment can pre-edit a control program to realize control of the driving motor 31. For example, the motor controller 32 is a PLC logic controller, and logic control is realized through logic programming, which is a conventional technical means in the art and will not be described in detail here.

[0042] The working process of the energy-saving cleaning device will be described in detail below. Figure 2 First, the energy-saving cleaning device is started by remote control through the Wifi connection mode.

[0043] Then, the pressure switch 2 is used to detect the liquid pressure in the liquid storage pump 1 in real time.

[0044] If the liquid pressure is lower than the preset threshold, the pressure switch 2 is in the closed state. At this time, the motor controller 32 controls the driving motor 31 to start, so as to control the liquid storage pump 1 to suck liquid and pressurize.

[0045] As the liquid pressure in the liquid storage pump 1 continuously rises, when the liquid pressure is higher than the preset threshold, the pressure switch 2 switches to the open state. At this time, the motor controller 32 controls the driving motor 31 to close, so as to control the liquid storage pump 1 to stop working, and the energy-saving cleaning device is in the standby state. In the standby state, cleaning operation can be performed at any time.

[0046] When cleaning is needed, the control switch of the cleaning part 4 is turned on, so that the liquid flows out from the liquid outlet pipe 102, and then the cleaning part 4 starts to spray. During the cleaning process, the control switch can be turned off at any time to end the cleaning.

[0047]

[0048] ​It can be understood that, in the continuous cleaning process, as the liquid pressure in the liquid storage pump 1 is continuously reduced, if the liquid pressure is always below the preset threshold, the pressure switch 2 is always kept closed, so as to continuously drive the liquid storage pump 1 to pump and pressurize the liquid, so as to ensure the continuous spraying output of the cleaning part 4. When stopping cleaning, the liquid pressure in the liquid storage pump 1 is continuously increased, if the liquid pressure is higher than the preset threshold, the pressure switch 2 is switched to the open state, so as to save the electric energy for the next cleaning operation.

[0049] In the above embodiment, preferably, the motor controller 32 has a Bluetooth connection module 321. The Bluetooth connection module 321 can be connected to the mobile phone application (App) through Bluetooth, so as to set the rotating speed of the driving motor 31 through the mobile phone application. Thus, the rotating speed of the driving motor 31 can be freely set according to the user's needs, and the rotating speed of the driving motor 31 can control the speed of the liquid storage pump 1 to pump the liquid, and then adjust the liquid spraying pressure when the cleaning part 4 is cleaning, so as to meet the needs of different scenes.

[0050] In the above embodiment, more preferably, the motor controller 32 also has a Wifi connection module 322. The Wifi connection module 322 can be connected to the wireless network to realize remote network permission configuration. In addition, preferably, after completing the remote network permission configuration, the start and stop of the motor controller can be realized through the cooperation of the pressure switch 2, the Bluetooth connection module 321 and the Wifi connection module 322. Thus, compared with the traditional mechanical button control mode, the problem of short service life caused by rusting and poor contact of the button in the environment with more water mist in the cleaning place is avoided, and the service life of the energy-saving cleaning equipment is improved.

[0051] As shown in Figure 3 In the above embodiment, preferably, the energy-saving cleaning equipment also includes a cleaning agent supply part 5, and the cleaning agent supply part 5 stores a cleaning agent. Specifically, the cleaning part 4 has a liquid channel 41 and a cleaning agent channel 42 which are not connected to each other, the liquid channel 41 is connected with the liquid outlet pipe 102, and the cleaning agent channel 42 is connected with the cleaning agent supply part 5 through the cleaning agent pipe 103. And, the liquid channel 41 is provided with a liquid switch 411 for controlling the opening and closing of the liquid channel, and the cleaning agent channel 42 is provided with a cleaning agent switch 421 for controlling the opening and closing of the cleaning agent channel. Thus, during the cleaning operation, the spraying of the cleaning agent can be controlled through the cleaning agent switch 421, and the spraying of the cleaning liquid can be controlled through the liquid switch 411, so as to improve the overall cleaning effect.

[0052] In addition, the cleaning agent supply part 5 is detachably mounted on the liquid storage pump 1. In another embodiment, the cleaning agent supply part 5 can also be separately provided, and the specific selection can be made as needed.

[0053] In summary, the energy-saving cleaning equipment provided by the embodiments of the present application has the following beneficial effects:

[0054] (1) The pressure switch 2 is arranged to automatically detect the liquid pressure in the liquid storage pump 1, so as to cooperate with the pressure control part 3 to automatically control the pressure, thereby avoiding continuous operation of the driving motor 31 and saving power consumption.

[0055] (2) The Bluetooth connection enables the user to freely set the rotating speed of the driving motor 31 according to the requirement, so as to adjust the liquid injection pressure when the cleaning part 4 is cleaning, thereby meeting the requirement of different scenes.

[0056] (3) The pressure switch, the Bluetooth connection module and the Wifi connection module cooperate with each other to realize remote control of the start and stop of the motor controller, thereby avoiding the problem that the keys are easily corroded, aged, have poor contact and have short service life in the environment with much water mist in the cleaning place, and improving the service life of the energy-saving cleaning equipment.

[0057] (4) The liquid channel 41 and the cleaning agent channel 42 are integrated on the cleaning part 4, so as to realize cooperative injection of the cleaning agent and the cleaning liquid, thereby improving the overall cleaning effect.
