Description

Technical Field

[0001] This application relates to the field of steam cleaning technology, and in particular to a ready-to-use cleaning machine system. Background Technology

[0002] A steam cleaner is a type of cleaning equipment. The working principle of a steam cleaner is to generate steam at high temperatures in a boiler. The steam accelerates the movement of molecules on the dirt surface and breaks down the binding force between them, thereby eliminating various stubborn stains. It is an environmentally friendly cleaning device that does not require any cleaning agents.

[0003] One related technology describes a ready-to-use steam cleaner, which includes a housing, a water pump and a boiler fixedly installed inside the housing, and a water tank and a nozzle that can be opened or closed fixedly connected to the housing. The boiler and the water tank are connected through the water pump, and the nozzle is connected to the boiler. When needed, the water pump first draws a certain amount of water from the water tank and sends it into the boiler. Then, the boiler quickly heats the water in the boiler to form steam. Finally, the nozzle is opened, and the steam is ejected from the nozzle.

[0004] In the process of developing this application, it was found that the technology has at least the following problems: when the boiler stops heating and begins to cool, the pressure inside the boiler decreases accordingly. The low-pressure environment inside the boiler causes the boiler to directly draw water from the water tank into the boiler, resulting in excessive water in the boiler. Utility Model Content

[0005] In order to minimize the risk of water being drawn into the water tank due to boiler cooling and pressure reduction, this application provides a ready-to-use cleaning machine system.

[0006] The ready-to-use cleaning machine system provided in this application adopts the following technical solution:

[0007] A ready-to-use cleaning machine system includes a housing, in which a water pump and a boiler are fixedly installed. A water tank and a nozzle that can be opened or closed are also fixedly connected to the housing. The boiler and the water tank are connected through the water pump, and the nozzle is connected to the boiler. An air intake valve is also fixedly installed inside the housing. The air intake of the air intake valve is connected to the atmosphere, and the air outlet of the air intake valve is connected to the boiler.

[0008] By adopting the above technical solution, when using the cleaning machine, the water pump first draws water from the tank into the boiler. The boiler then heats the water to generate steam. Finally, the nozzles are opened, and the steam is ejected from the nozzles to perform the cleaning work. After use, the boiler begins to cool, and the internal pressure decreases. At this time, the suction valve opens, allowing outside air to enter the boiler, balancing the internal and external pressures and preventing the boiler from directly drawing water from the tank.

[0009] Preferably, a pressure switch is fixedly installed on the boiler, the pressure switch is used to detect the internal pressure of the boiler, and the pressure switch is electrically connected to the boiler.

[0010] By adopting the above technical solution, the pressure switch can monitor the pressure changes inside the boiler. When the boiler heating causes the internal pressure to rise to a preset threshold, the pressure switch can disconnect the power supply to the circuit in time, thereby controlling the boiler to stop heating and preventing the internal pressure of the boiler from becoming too high.

[0011] Preferably, the boiler is also equipped with a pressure relief valve.

[0012] By adopting the above technical solution, when the internal pressure of the boiler exceeds the safety limit, the pressure relief valve will automatically open to release the excess pressure inside the boiler, thereby ensuring the safety of boiler operation and minimizing equipment damage or even safety accidents caused by excessive pressure.

[0013] Preferably, the nozzle includes a venting valve and an extension tube, the extension tube being installed through and fixedly mounted on the outer casing, and one end of the extension tube located inside the outer casing being connected to the boiler via the venting valve.

[0014] By adopting the above technical solution, the vent valve can control the discharge of steam from the extension pipe, allowing operators to adjust the steam release volume and speed by controlling the opening degree of the vent valve's pressing part according to actual cleaning needs. When a large amount of steam is required for intensive cleaning, the vent valve can also be closed when the cleaning machine is not in use, ensuring the boiler remains in a sealed state and improving its heating efficiency.

[0015] Preferably, a handle is fixedly provided on the top of the housing.

[0016] By adopting the above technical solution, the handle fixedly installed on the top of the shell can provide users with a convenient grip position, making it easier and less strenuous to operate the cleaning machine, and improving the convenience and comfort of use.

[0017] Preferably, the vent valve is a push-button manual vent valve. A steam injection button is slidably provided on the top side of the handle in the vertical direction. A movable pressure rod extending into the housing is fixedly connected to the bottom of the steam injection button. A rotating pressure plate is provided above the vent valve. One end of the rotating pressure plate is rotatably connected to the housing. The top side of the other end of the rotating pressure plate abuts against the bottom of the movable pressure rod. The bottom side of the middle part of the rotating pressure plate abuts against the pressing part of the vent valve.

[0018] By adopting the above technical solution, when the user presses the steam injection button, the movable lever moves downward, pushing one end of the rotating pressure plate down. This causes the middle part of the rotating pressure plate to press down the vent valve's pressing part, thereby opening the vent valve and allowing steam to be released. During the pressing of the steam injection button, the rotating pressure plate acts as a lever, making pressing the button easier. When the steam injection button is released, the vent valve's pressing part, via the rotating pressure plate, lifts the steam injection button back up. The user can directly press the steam injection button while holding the handle to release steam, facilitating one-handed operation.

[0019] Preferably, the water tank is transparent.

[0020] By adopting the above technical solution, the transparent tank wall allows users to intuitively observe the water level inside the tank, promptly understand the remaining water volume, and replenish the water in time when it is insufficient, ensuring the smooth progress of the cleaning work.

[0021] Preferably, water level markings are provided on the side wall of the water tank.

[0022] By adopting the above technical solution, the water level scale can provide users with more accurate water level information. Users can clearly know the specific amount of water in the tank, so as to arrange the cleaning work more reasonably and avoid interruption of the cleaning work due to inaccurate water volume estimation.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting an air intake valve, the pressure inside and outside the boiler is balanced during boiler cooling, which avoids the boiler directly drawing water from the water tank and prevents excessive water in the boiler.

[0025] 2. By setting pressure switches and pressure relief valves, the internal pressure of the boiler is monitored and regulated to prevent damage to the equipment caused by excessively high or low pressure, thereby improving the safety and stability of the cleaning machine;

[0026] 3. By setting up a handle, vent valve, extension tube, steam injection button, rotating pressure plate, and movable pressure rod, the user can press the steam injection button with their thumb while holding the handle. The movable pressure rod moves downward, pushing one end of the rotating pressure plate down, so that the middle part of the rotating pressure plate presses down on the vent valve, thereby opening the vent valve and realizing the release of steam, which is convenient for the user to operate with one hand.

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a ready-to-use cleaning machine system. (Refer to...) Figures 1 to 3 The system includes an outer casing 1 and a water tank 4. The water tank 4 is transparent, and water level markings 41 are provided on its side wall. The water tank 4 serves as the base of the entire cleaning machine and can be made of transparent plastic. The outer casing 1 is fixedly mounted on top of the water tank 4. A water inlet pipe 6 is installed inside the outer casing 1. The bottom end of the water inlet pipe 6 is connected to the water tank 4, and the top of the water inlet pipe 6 passes through the outer casing 1 and is fixed thereto. A removable plug 61 is also provided on the top of the water inlet pipe 6 to seal it.

[0033] Reference Figure 1 A water pump 3 and a boiler 2 are fixedly installed inside the outer casing 1. A nozzle 5 that can be opened or closed is also fixedly installed on the outer casing 1. The boiler 2 is connected to the water tank 4 through the water pump 3, and the nozzle 5 is connected to the boiler 2.

[0034] Reference Figure 3 An air intake valve 21 is also fixedly installed inside the outer casing 1. The air inlet of the air intake valve 21 is connected to the atmosphere, and the air outlet of the air intake valve 21 is connected to the boiler 2. When the boiler 2 cools down and the internal pressure decreases, the air intake valve 21 opens, and the outside atmosphere enters the boiler 2 through the air intake valve 21 to balance the internal and external pressure of the boiler 2, so as to prevent the boiler 2 from directly sucking in the water in the water tank 4.

[0035] To prevent excessive internal pressure in boiler 2 and ensure its safety, refer to... Figure 3A pressure switch 22 is fixedly installed on the boiler 2. The pressure switch 22 is used to detect the internal pressure of the boiler 2 and is electrically connected to the boiler 2. When the internal pressure of the boiler 2 rises to a preset threshold due to heating, the pressure switch 22 can control the boiler 2 to cut off the power to prevent the internal pressure of the boiler 2 from becoming too high. The boiler 2 is also equipped with a pressure relief valve 23. When the internal pressure of the boiler 2 exceeds the safety limit, the pressure relief valve 23 will automatically open to release the excess pressure inside the boiler 2.

[0036] To facilitate one-handed operation of the cleaning machine, please refer to... Figure 1 and Figure 2 The nozzle 5 includes a vent valve 51 and an extension tube 52. The extension tube 52 passes through and is fixedly mounted on the outer casing 1, and one end of the extension tube 52 located inside the outer casing 1 is connected to the boiler 2 via the vent valve 51. A handle 11 is fixedly mounted on the top of the outer casing 1. The handle 11 includes a horizontal portion parallel to the top of the outer casing 1 and a connecting portion for connecting the horizontal portion to the boiler 2. A steam injection button 12 is slidably mounted on the top side of the handle 11 in the vertical direction, and a movable pressure rod 13 extending into the outer casing 1 is fixedly connected to the bottom of the steam injection button 12. The vent valve 51 is a push-button manual vent valve 51, which has a pressing part for controlling the opening and closing of the vent valve 51. A rotating pressure plate 14 is mounted above the vent valve 51. One end of the rotating pressure plate 14 is rotatably connected to the outer casing 1, and the top side of the other end of the rotating pressure plate 14 abuts against the bottom of the movable pressure rod 13. The bottom side of the middle part of the rotating pressure plate 14 abuts against the pressing part 511 of the vent valve 51. Specifically, a rotating frame 15 is fixedly installed inside the outer casing 1, and the rotating pressure plate 14 is rotatably engaged with the rotating frame 15.

[0037] Reference Figure 1 and Figure 2 When the user lifts the cleaning machine by holding the handle 11 and presses the steam injection button 12 with their thumb, the movable pressure rod 13 moves downward, pushing one end of the rotating pressure plate 14 down. This causes the middle part of the rotating pressure plate 14 to press down the pressing part 511 of the vent valve 51, thereby opening the vent valve 51 and releasing steam. Furthermore, during the pressing of the steam injection button 12, the rotating pressure plate 14 acts as a lever, making pressing the steam injection button 12 easier. When the steam injection button 12 is released, the pressing part 511 of the vent valve 51 lifts the steam injection button 12 up via the rotating pressure plate 14. The user can directly press the steam injection button 12 while holding the handle 11 to release steam, facilitating one-handed operation.

[0038] The implementation principle of a ready-to-use cleaning machine system according to an embodiment of this application is as follows: When preparing to use the cleaning machine, the user first checks whether there is enough water in the water tank 4 by looking at the water level scale 41 on the side wall of the transparent water tank 4. If not, clean water is injected into the water tank 4 through the water injection pipe 6. The plug 61 at the top of the water injection pipe 6 ensures that no water splashes out or external impurities enter the water tank 4 during the water injection process.

[0039] When using the cleaning machine, water pump 3 operates for a period of time, drawing some water from water tank 4 and transferring it to boiler 2. Boiler 2 rapidly heats the water, quickly generating steam. While boiler 2 is operating, pressure switch 22 monitors the internal pressure in real time. When the pressure reaches a preset threshold, pressure switch 22 sends a signal to stop heating boiler 2, preventing excessive pressure inside boiler 2.

[0040] When boiler 2 cools down, the internal pressure of boiler 2 decreases due to the cooling process. The suction valve 21 will automatically open, allowing outside air to enter the boiler 2 and balancing the internal and external pressures. This helps to prevent boiler 2 from directly drawing water from water tank 4, which could result in excessive water inside boiler 2.

[0041] During the cleaning operation, the user lifts the cleaning machine by holding the handle 11. When the user needs steam for cleaning, they press the steam injection button 12 with their thumb. The steam injection button 12 moves the movable pressure rod 13 downward, pushing one end of the rotating pressure plate 14 down. The middle of the rotating pressure plate 14 presses down the pressing part 511 of the vent valve 51, thereby opening the vent valve 51. Steam flows from the boiler 2 through the vent valve 51 and the extension pipe 52, and finally exits from the nozzle 5, acting on the surface of the item to be cleaned. When the steam injection button 12 is released, the pressing part 511 of the vent valve 51 will lift the steam injection button 12 by rotating the pressure plate 14, closing the vent valve 51 and stopping the steam injection.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
