[0002] A steam cleaning machine, also known as a saturated steam cleaning machine, is a cleaning device that uses the high temperature and external high pressure of saturated steam to clean oil stains and dirt on the surface of parts and vaporize and evaporate them. Existing steam cleaning machines generally include a cleaning machine body and a handle assembly connected to the steam engine body through a connecting pipe. The steam engine body generates steam through a steam boiler therein and supplies steam to the handle assembly through a connecting pipe. The handle assembly is used to control the injection and injection position of steam. However, existing steam cleaning machines often encounter stubborn stains that are difficult to clean directly with steam alone during use. At this time, additional cleaning liquid is required for auxiliary cleaning. Therefore, it is very necessary to design a handle assembly with a container for storing cleaning liquid and which can conveniently control the mixing of cleaning liquid and steam.

[0019] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0020] The utility model discloses a handle assembly for a steam cleaning machine. Figure 1 and Figure 2As shown, it includes a handle body 10, on which is provided a mixer 30 with three interfaces, and a nozzle 20, a steam connector 40 and a liquid storage container 50 respectively connected to the three interfaces of the mixer 30, wherein the steam connector 40 is used to be connected to the cleaning machine body through a connecting pipe to receive the steam generated by the cleaning machine body, and the liquid storage container 50 is used to store cleaning liquid.

[0021] In this embodiment, if Figure 2 and Figure 3 As shown, the mixer 30 is preferably a Venturi mixer 30 structure, which includes a mixing interface for connecting to the inlet of the nozzle 20, a steam interface for connecting to the outlet of the steam joint 40, and a cleaning liquid interface for connecting to the liquid storage container 50; the liquid storage container 50 has a liquid storage cavity, and a liquid outlet and an air inlet connected to the liquid storage cavity. The liquid storage container 50 is provided with a rubber plug 80 for controlling the opening or closing of the air inlet at the corresponding air inlet, and a duckbill valve 7 is provided at the corresponding liquid outlet of the liquid storage container 50. 0 and a liquid outlet connector 60 is provided on the outside of the corresponding duckbill valve 70, which is used to be connected to the cleaning liquid interface of the mixer 30 through a pipeline. The duckbill valve 70 is used to limit the fluid to flow in one direction only from the liquid storage container 50 to the mixer 30. In this way, when the handle body 10 is held to spray steam, the steam generated by the cleaning machine body quickly flows through the mixer 30 through the steam connector 40 and is sprayed out from the nozzle 20, which will generate negative pressure suction at the cleaning liquid interface. At this time, by controlling The state of the plug 80 of the liquid storage container 50 (the state of the air inlet) can control whether the cleaning liquid in the liquid storage container 50 flows into the mixer 30 to adapt to different working environments. Specifically: when the plug 80 is pulled out to make the air inlet in an open state, the liquid storage cavity of the liquid outlet container is connected to the external air. At this time, the negative pressure suction formed at the cleaning liquid interface can make the duckbill valve 70 open to suck the cleaning liquid in the liquid storage container 50 into the mixer 30, and after mixing with the steam, it is sprayed out together from the nozzle 20. At this time, the handle body 10 is in a state of spraying a mixed liquid of steam and cleaning liquid. In this state, stubborn stains that are difficult to clean with steam can be better cleaned; on the contrary, when the plug 80 is blocked in the air inlet so that the air inlet is in a closed state, the liquid storage cavity of the liquid storage container 50 is not connected to the outside and is in a vacuum state. In this way, the negative pressure suction formed at the cleaning liquid interface cannot make the duckbill valve 70 open. In this state, the cleaning liquid in the liquid storage container 50 does not flow into the mixer 30, and the handle body 10 only sprays steam.

[0022] In this embodiment, if Figure 3As shown, the plug 80 is made of rubber material, and includes a plug ring 81 fixedly embedded in the air inlet of the liquid storage container 50, a plug head 82 for blocking the inner hole of the plug ring 81, and a connecting arm 83 connected between the plug ring 81 and the plug head 82. This not only ensures the effect of the plug 80 in sealing the air inlet, but also prevents the plug 80 from being lost; preferably, the plug ring 81 is also provided with a first baffle 811 located in the liquid storage container 50 and abutting against the inner wall of the liquid storage container 50, and a second baffle 812 located outside the liquid storage container 50 and abutting against the outer wall of the liquid storage container 50, which can effectively improve the installation stability of the plug ring 81 in the air inlet. If needed, the first baffle 811 and the liquid storage container 50, as well as the second baffle 812 and the liquid storage container 50, can also be bonded with glue to improve the connection strength.

[0023] In this embodiment, the handle body 10 is preferably a gun-type structure, the nozzle is arranged on the front end of the gun body, the mixer 30 is arranged in the gun body and its mixing interface is integrally connected to the nozzle, the liquid storage container 50 is horizontally extended and arranged at the rear end of the gun body, the rubber plug 80 is arranged on the rear end of the liquid storage container 50 or on the top wall of the liquid storage container 50, and the steam joint 40 is arranged on the bottom of the gun handle or in the gun handle.

[0024] Compared with the prior art, the utility model has a simple and reasonable structure. Through the cooperation of the Venturi mixer, the duckbill valve and the rubber plug, it can conveniently control whether the cleaning liquid in the liquid storage container flows into the mixer, so that the handle body can be conveniently switched to spray steam or a mixture of steam and cleaning liquid according to the working environment to achieve better cleaning effect.

[0025] The above disclosure is only an embodiment of the present invention, but the present invention is not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
