the other end of the first water pump 153 is connected to an inlet of the first check valve 154, and the first water pump 153 is further connected to the fourth controller 124 through a second transformer 125; the first water pump 153 is a high-pressure plunger pump, and the fourth controller 124 is connected to the main control board 110;
the outlet end of the first check valve 154 is connected to the heating body 140.
In this embodiment, specifically, the inlet end of the filter 151 is connected to the second outlet end 132c of the second three-way valve 132. At this time, if the steam cleaner is in the activated state, the water in the water tank 130 flows in from the inlet 131a of the first three-way valve 131, then flows from the first outlet 131b of the first three-way valve 131 to the inlet 132a of the second three-way valve, and finally flows from the second outlet 132c of the second three-way valve to the inlet of the filter 151.
At this time, the water flowing into the filter 151 is filtered by the filter material to remove the magnesium ions, calcium ions and other mineral chemicals, and then flows to the first water pump 153, so that the first water pump 153 pumps the water into the heating body 140.
A first check valve 154 is further provided between the first water pump 153 and the heating body 140 in order to prevent high-temperature water or steam in the heating body 140 from flowing back to the first water pump 153 and the water tank 130. And the first water pump 153 adopts a high pressure plunger pump, and water is primarily filtered through the filter 151 before entering the high pressure plunger pump, so as to reduce damage to the high pressure plunger pump and delay the time of scaling in the heating body 140.
In one embodiment, as shown in fig. 5 and 6, the pressure limiting protection assembly 160 comprises a pressure switch 161 and a pressure valve 162 arranged on the connecting line; the pressure switch 161 is connected to the main control board 110, and the pressure valve 162 is further provided with a pressure relief exhaust pipe 163, and the pressure relief exhaust pipe 163 is communicated to the water tank 130.
In this embodiment, the pressure limiting protection assembly 160 is used for monitoring the pressure in the steam cleaner in real time. If the steam cleaning device is in an on state, after the water in the heating body 140 is heated to high-temperature steam, if a user does not press the air injection switch on the steam spray gun 300, the steam is continuously accumulated in the pipeline in the steam cleaning device to cause pressure increase, and if the steam is not released in time, the pipeline pressure is too high to damage the pipeline.
In this embodiment, in order to avoid scale generation after the heating body is used for a long time and influence the efficiency of the heating body,
at this time, the pressure at the outlet of the heating body 140 can be monitored in real time by the pressure limiting protection assembly 160. Specifically, the upper limit of the pressure of the relief pressure of the safety valve 161 is set to P1 (for example, equal to 2Bar), the upper limit of the pressure switch 161 sending the stop signal is set to P2 (for example, equal to 1.5Bar), when the pressure at the outlet of the heating body 140 rises to P2 due to the continuous accumulation of gas, if the pressure switch 161 detects the pressure value corresponding to the P2 at this time, a stop signal is generated and sent to the main control board 110 to control the heating body 140 to stop water boiling to continue to generate water vapor. However, in the actual operation process, when the pressure switch 161 generates a shutdown signal due to too fast pressure rise or its own failure, the pressure switch 162 also serves as a second layer protection when the corresponding pressure value of P2 is not detected. When the pressure in the pipeline rapidly exceeds P2 and reaches P1, the pressure valve 162 releases the pressure in time, i.e. the gas in the pipeline is exhausted through the pressure relief exhaust pipe. For example, the other end of the pressure relief vent pipe is placed in the water tank 130, and at this time, the gas in the pipeline can be discharged into the water in the water tank through the pressure relief vent pipe 163 at a moment, so that the pipeline is effectively protected.
In one embodiment, as shown in fig. 6, the temperature limiting protection assembly 170 includes a first temperature sensor 171, a second temperature sensor 172, and a temperature switch 173; the first temperature sensor 171, the second temperature sensor 172 and the temperature switch 173 are all connected to the main control board 110.
In the present embodiment, the first temperature sensor 171, the second temperature sensor 172, and the temperature switch 173 are provided on the outer wall of the heating body 140, and the temperature of the high-temperature steam inside the heating body 140 can be estimated by detecting the temperature of the outer wall of the heating body 140. For example, the upper temperature limit of the stop signal sent by the first temperature sensor 171 or the second temperature sensor 172 is smaller than the upper temperature limit of the stop signal sent by the temperature switch 173.
Specifically, the upper temperature limit of the shutdown signal sent by the first temperature sensor 171 and the second temperature sensor 172 is set to T1 (e.g., equal to 180 ℃), the upper temperature limit of the shutdown signal sent by the temperature switch 173 is set to T2 (e.g., equal to 300 ℃), and when the temperature of the outer wall of the heating body 140 rises to T1, if the temperature corresponding to T1 is detected by the first temperature sensor 171 or the second temperature sensor 172 at this time, a shutdown signal is generated and sent to the main control board 110 to control the heating body 140 to stop heating water and continue to generate steam. However, during actual operation, when the temperature of the outer wall of the heating body 140 rises too fast and the shutdown signal is generated without detecting the temperature value corresponding to T1, the temperature switch 173 is also used as a second layer protection. That is, when the temperature of the outer wall of the heating body rapidly exceeds T1 and reaches T2, the temperature switch 173 will generate a shutdown signal in time to stop the heating body 140 from boiling water to prevent dry heating, so as to effectively protect the heating body 140.

an emergency stop switch 181 disposed on the cart body 100, wherein the emergency stop switch 180 is connected to the main control board 110;

The dry-wet switching knob 182 is disposed on the cart body 100, and the main control board 110 can send a signal for adjusting the rotation speed of the water pump to the water pipe assembly 160 to control the amount of water pumped to the heating body 140 by the water pipe assembly 160 in a unit time, so as to control the humidity in the high-temperature steam. For example, when the amount of water pumped into the heating body 140 by the water pipe assembly 160 per unit time is reduced, the high temperature steam is partially dry; when the amount of water pumped into the heating body 140 by the water pipe assembly 160 per unit time increases, the high temperature steam is wet.
