[0030] like Figure 1 As shown in the illustration, a control handle provided in this embodiment of the present invention includes a hose 9, a handle body 1, a control circuit board 3, and a button 4. The hose 9 is used to connect to the air duct system of the fabric cleaning machine, forming a channel for conveying wastewater and air. The handle body 1 is connected to the hose 9, providing a gripping structure for operation and control. The control circuit board 3 is disposed inside the handle body 1 and is communicatively connected to the fabric cleaning machine via a connecting cable assembly 7. The button 4 is movably mounted on the handle body 1, at least partially exposed outside the handle body 1. When the button 4 is pressed, its internal structure presses against the control circuit board 3, triggering the control circuit board 3 to generate a water spray command, thereby activating the water spray function.

[0031] While the above embodiment achieves the function of continuous water flow triggered by pressing, after prolonged use, water flowing inside the control handle may seep into the control circuit board 3, causing a short circuit. To avoid this problem, such as... Figure 2 As shown, in this embodiment, a waterproof cover 5 is provided inside the handle body 1. The waterproof cover 5 covers the control circuit board 3, providing a physical barrier to prevent water or other liquids from contacting the control circuit board 3. Meanwhile, to facilitate the smooth passage of the bottom of the button 4, a button hole for insertion is provided at the corresponding position of the waterproof cover 5, and an elastic sealing sleeve 2 is covered over the button hole. When the button 4 is pressed, it squeezes the sealing sleeve 2, causing it to deform until it presses against the control circuit board 3 through the deformed sealing sleeve 2, triggering the control circuit board 3 to generate a water spray command. This ensures a tight seal, preventing water from seeping into the interior through the button hole.

[0032] In this embodiment, the sealing sheath 2 is a rubber part. The flexibility of the rubber part enables it to completely cover the button hole on the waterproof cover 5, forming a good sealing barrier in structure and preventing liquid from seeping into the control circuit board 3 area from the gap. Compared with the traditional sealing part made of hard material, the rubber part can better fit the waterproof cover 5 and the button 4, reducing the problem of sealing gap caused by processing error and significantly improving the waterproof performance of the assembly. In addition, the rubber part will deform controllably when subjected to external force, and can quickly restore to its original state after the external force is removed, thereby always maintaining the stability of the sealing performance.

[0033] Preferably, the connecting line assembly 7 is composed of a connecting line and a protective shell. In order to avoid the reduction of waterproof performance caused by the interface between the protective shell and the waterproof cover 5, a waterproof plug 6 is designed. The waterproof plug 6 is internally provided with a passage for the passage of the connecting line assembly 7, and at the same time fills the gap between the connecting line assembly 7 and the waterproof cover 5. At the same time, the waterproof plug 6 is in interference fit with the connecting line assembly 7 and the waterproof cover 5. Through the waterproof plug 6, not only the sealing effect is improved, but also the stability of the connecting line assembly 7 during use is enhanced.

[0034] In an embodiment, a lamp bead can be integrated on the control circuit board 3, and the button 4 is made of light-transmitting rubber and the sealing sheath 2 is made of transparent plastic part. When the control handle is in a working state, the structure can provide clear illumination indication, significantly enhancing the user's interactive experience and use convenience.

[0035] As shown in Figures 3-4 The utility model embodiment further provides a cloth cleaning machine, the cleaning machine includes bottom disc 13, main circuit board 14, diaphragm pump 15 and above-mentioned control handle. Wherein, main circuit board 14 is connected with control circuit board 3 by connecting line assembly 7, and main circuit board 14 is connected with diaphragm pump 15, for receiving and controlling diaphragm pump 15 according to the signal of control circuit board 3 and opening, be equipped with inlet pipe 16 on diaphragm pump 15, and diaphragm pump 15 is connected with outlet pipe 8 arranged in hose 9, when user uses water spraying function, through the button 4 of control handle triggers control circuit board 3, control circuit board 3 sends signal to main circuit board 14 through connecting line assembly 7, and main circuit board 14 controls diaphragm pump 15 and draws cleaning liquid from clean water bucket to outlet pipe 8, realizes water outlet function.

[0036] Further, it further includes air duct pipe assembly 11 installed on bottom disc 13 and spray head 10 connected with outlet pipe 8, and the spray head 10 at least partially extends out of the handle body 1, realizing efficient spraying of cleaning liquid.

[0037] As shown in Figure 5As shown, the air duct pipe assembly 11 comprises a first joint 102, a second joint 103 and an isolation hole 100, the first joint 102 is connected with the bottom plate 13, the second joint 103 is connected with the hose 9, and the control handle is installed on the bottom plate 13. The water outlet pipe 8 passes through the isolation hole 100 into the hose 9, and the separately arranged isolation hole 100 can provide an independent passage for the water outlet pipe 8, preventing liquid backflow from affecting the air duct suction.

[0038] In the embodiment, a wire hole 101 is formed in the second joint 103, facilitating the connection line assembly 7 to be drawn out from the bottom plate 13 to the control circuit board 3 inside the control handle. At the same time, an air leakage prevention plug 12 is arranged at the wire hole 101, the air leakage prevention plug 12 is internally provided with a passage for fixing the connection line assembly 7 and filling the gap of the wire hole 101, preventing air leakage from the wire hole 101 and reducing the air duct efficiency.

[0039] When the fabric cleaning machine is started, the motor inside the bottom plate 13 drives the air blower to work. The high-speed operation of the air blower forms a low-pressure area in the air duct of the hose 9 and the air duct pipe assembly 11, and air flows rapidly along the air duct from the spray head 10 to the sewage tank, generating strong suction. When the spray head 10 contacts the cleaning surface, the air duct suction will suck the sewage and dirt on the surface into the handle body 1 inside, and then flow along the air duct through the hose 9 to the sewage tank on the bottom plate 13.
