Description

Technical Field

[0001] This utility model relates to the field of sweeping machines, specifically to a steam heating water circuit system for a sweeping machine. Background Technology

[0002] In existing technologies, sweeping machines, especially handheld sweeping machines, are generally equipped with a water system. The water system mainly consists of a water tank, a water pump, and a heating device. It uses the water pump to output water from the water tank to the heating device for heating. The limitation of this water system is that, because the water system is simple, it requires a large battery to heat the water quickly during use, making the machine bulky and often unable to reach the set temperature quickly enough to output steam effectively. Utility Model Content

[0003] To address the technical problems of existing sweeper water systems, such as their simplistic design and inability to effectively output steam, this invention provides a steam-heated water system for a sweeper. The specific technical solution is as follows:

[0004] A steam-heated water circuit system for a sweeper includes a water tank, a water pump, a first three-way solenoid valve, a second three-way solenoid valve, a heating device, a roller spray block, and a steam spray block. The water tank is installed in the main body of the sweeper. The outlet of the water tank is connected to the water pump, and the outlet of the water pump is connected to the inlet of the first three-way solenoid valve. The normally open end of the first three-way solenoid valve is connected to the inlet of the second three-way solenoid valve. The heating device is installed inside the sweeper's floor brush and contains a first heating pipe and a second heating pipe. The normally closed end of the second three-way solenoid valve is connected to the inlet of the first heating pipe, and the outlet of the first heating pipe is connected to the steam spray block. The normally closed end of the first three-way solenoid valve is connected to the inlet of the second heating pipe, and the outlet of the second heating pipe is connected to the inlet of the water tank. The normally open end of the second three-way solenoid valve is connected to the roller spray block.

[0005] As a preferred embodiment of this utility model, during preheating, the normally closed port of the first three-way solenoid valve is opened while the normally open port is closed, and the water in the water tank returns to the water tank after passing through the second heating tube.

[0006] As a preferred embodiment of this utility model, when steam needs to be output, the normally closed port of the first three-way solenoid valve is closed and the normally open port is open, the normally closed port of the second three-way solenoid valve is open and the normally open port is closed, and the first heating tube outputs steam to the steam spray block.

[0007] As a preferred embodiment of this utility model, when water needs to be output to the drum, the normally closed port of the first three-way solenoid valve is closed and the normally open port is open, and the normally closed port of the second three-way solenoid valve is closed and the normally open port is open to directly output water to the drum spray block.

[0008] As a preferred embodiment of this utility model, the roller water spray block and the steam water spray block are installed at the floor brush of the sweeper, with the roller water spray block close to the roller and the steam water spray block away from the roller.

[0009] As a preferred embodiment of this utility model, the heating device is internally equipped with a heating cast aluminum, and the first heating tube and the second heating tube are embedded in the heating cast aluminum.

[0010] As a preferred embodiment of this utility model, it also includes a water electrolysis device, through which the water in the water tank passes before reaching the water pump.

[0011] Beneficial effects: Compared with the prior art, the heating water system of this utility model sweeper, by adding a first three-way solenoid valve and a second three-way solenoid valve in conjunction with a heating device, a roller spray block and a steam spray block, allows the water in the water tank to be preheated to a medium temperature when the sweeper is not cleaning, such as at a base station. When the sweeper is cleaning, the solenoid valve is switched between normally open and normally closed, and the heating device heats the water at a high temperature again, which can quickly turn the medium-temperature water into steam. It is quick and convenient to use and highly practical. Attached Figure Description

[0021] like Figure 1-6 As shown, a steam heating water circuit system for a sweeper includes a water tank 1, a water pump 2, a first three-way solenoid valve 3, a second three-way solenoid valve 4, a heating device 5, a roller spray block 6, and a steam spray block 7. The water tank 1 is installed in the main body A of the sweeper. The outlet of the water tank 1 is connected to the water pump 2. The outlet of the water pump 2 is connected to the inlet of the first three-way solenoid valve 3. The normally open end of the first three-way solenoid valve 3 is connected to the inlet of the second three-way solenoid valve 4. The heating device 5 is installed inside the sweeper's floor brush B. The heating device 5 contains a first heating pipe 51 and a second heating pipe 52. The normally closed end of the second three-way solenoid valve 4 is connected to the inlet of the first heating pipe 51. The outlet of the first heating pipe 52 is connected to the steam spray block 7. The normally closed end of the first three-way solenoid valve 3 is connected to the inlet of the second heating pipe 52. The outlet of the second heating pipe 52 is connected to the inlet of the water tank 1. The normally open end of the second three-way solenoid valve 4 is connected to the roller spray block 6.

[0022] like Figure 2 As shown, when the sweeper is on the base station, the heating water system preheats the water supply. The normally closed port of the first three-way solenoid valve 3 is opened while the normally open port is closed. Water from water tank 1 returns to water tank 1 after passing through the second heating pipe 52. After being preheated by the heating device 5 to, for example, 80°C, it returns to the water tank. This way, the water in the tank is hot after the sweeper leaves the base station, allowing it to heat up more quickly. The roller spray block and steam spray block are installed on the sweeper's floor brush. Figure 3 As shown, when steam is required, the normally closed port of the first three-way solenoid valve 3 closes while the normally open port opens, the normally closed port of the second three-way solenoid valve 4 opens while the normally open port closes, and the first heating pipe 51 outputs steam to the steam spray block 7, which then sprays steam onto the ground for sterilization. Figure 4As shown, when water needs to be output to the roller, the normally closed port of the first three-way solenoid valve 3 is closed and the normally open port is open, and the normally closed port of the second three-way solenoid valve 4 is closed and the normally open port is open, directly outputting water to the roller spray block 6. The roller spray block 6 can spray water onto the roller mop for cleaning on the side close to the roller.

[0023] like Figure 6 As shown, the heating device 5 has a heating cast aluminum 53 installed inside, and the first heating tube 51 and the second heating tube 52 are embedded in the heating cast aluminum 53, which can achieve rapid heating.

[0024] The sweeper's water system also includes an electrolyzing water device 8. Water in the water tank 1 passes through the electrolyzing water device 8 before reaching the water pump 2. The electrolyzed water has a better sterilization and disinfection effect. In addition, the water inlets of various parts are connected by water pipes to realize water transmission.

[0025] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be considered that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the protection scope of the present utility model.
