Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0029] like Figure 1-11 As shown in the figure, this application discloses a low-noise fabric cleaning machine, including a main body 1 and a cleaning brush head 2. The main body 1 includes a base 10 and a main body housing 20 covered on the base 10. A clean water tank 21 and a wastewater tank 22 are respectively provided on both sides of the main body housing 20. A clean water tank 30 and a wastewater tank 40 are respectively provided in the clean water tank 21 and the wastewater tank 22.
[0030] Specifically, the bottom of the clean water tank 21 is recessed to form a first mounting groove 25, and the bottom of the first mounting groove 25 is recessed to form a water inlet groove 26. A pin 261 protrudes from the bottom of the water inlet groove 26, and the wall of the water inlet groove 26 has a water inlet hole 262 and a water inlet connector 263 communicating with the water inlet hole 262. The bottom of the clean water tank 30 has a water outlet connector 31, which is a stepped tubular shape. Its two tubes of different diameters respectively mate with the first mounting groove 25 and the water inlet groove 26. The outer wall of the smaller diameter section of the tube is also fitted with a sealing ring to seal against the inner wall of the water inlet groove 26 and prevent clean water from overflowing. A support frame 32 is provided inside the water outlet connector 31. A piston rod 33 is vertically slidably arranged inside the support frame 32. A sealing plug 34 is provided at the lower end of the piston rod 33. A top pressure spring 35 is provided on the piston rod 33 between the sealing plug 34 and the top of the support frame 32. In the initial state, the top pressure spring 35 pushes the sealing plug 34 to seal the inner hole of the water outlet connector 31, keeping the clean water tank 30 sealed. When the clean water tank 30 is installed into the clean water trough 21, the water outlet connector 31 is placed in the first mounting groove 25 and the water inlet circular groove 26. Under the action of the ejector pin 261, the sealing plug 34 and the piston rod 33 are pushed upward, causing the sealing plug 34 to leave the inner hole of the water outlet connector 31. Thus, the clean water in the clean water tank 30 flows from the water outlet connector 31 into the water inlet circular groove 26, and then flows out from the water inlet hole 262 and the water inlet connector 263.
[0031] A steam generator 60 is installed inside the main housing 20. A bend connector 24 is located at the bottom of the main housing 20.

The steam outlet of the steam generator 60 is connected to the inner end of the bend connector 24, and the outer end of the bend connector 24 is connected to the cleaning brush head 2 via a steam hose (not shown in the figure). This forms a connection path of clean water tank 30 - water inlet connector 263 - steam generator 60 - bend connector 24 - steam hose - cleaning brush head 2. The clean water in the clean water tank 30 is heated into steam by the steam generator 60 and then delivered to the cleaning brush head 2 to clean the fabric products, effectively removing dust and stains from the fabric products.
[0032] The bottom of the sewage tank 22 is recessed and has a second mounting groove 27. A sewage hole 271 and an air vent 272 are provided through the bottom of the second mounting groove 27. A sealing gasket is also provided on the outside of the sewage hole 271 and the air vent 272 at the bottom of the second mounting groove 27. The bottom of the sewage tank 40 is spirally connected to a cap 41. The cap 41 has a sewage outlet 42 that mates with the sewage hole 271 and an air vent 43 that mates with the air vent 272. The sewage outlet 42 is the sewage inlet of the sewage tank 40, and the air vent 43 is the air outlet of the sewage tank 40. A sewage pipe 44 and an air outlet pipe 45 protrude upwards from the sewage outlet 42 and the air vent 43 on the cap 41. When the sewage tank 40 is installed into the sewage tank 22, the cap 41 is placed inside and mates with the second mounting groove 27. The bottom surface of the cap 41, in conjunction with the sealing gasket, seals the connection between the sewage hole 271 and the sewage outlet 42, and the connection between the air vent 272 and the air vent 43, preventing air leakage. An L-shaped bend 23 is provided at the bottom of the main housing 20. The outer end of the L-shaped bend 23 protrudes from the main housing 20 and is connected to the cleaning brush head 2 via a connecting hose 50. The inner end is connected to the sewage hole 271 via a pipe, thereby connecting to the sewage inlet of the sewage tank 40.
[0033] An air outlet trough plate 12 is provided on the base 10. The air outlet trough plate 12 has a downward-opening trough-shaped structure, and the trough cavity of the air outlet trough plate 12 forms an air cavity with the base 10. An air outlet mesh 11 is provided on the base 10, and the air cavity is connected to the air outlet mesh 11 to discharge gas from the machine. A fan assembly 70 is provided on the air outlet trough plate 12, and several arc-shaped air holes 13 are provided on the air outlet trough plate 12 at the air outlet end of the fan assembly 70. The arc-shaped air holes 13 are used to connect the air outlet end of the fan assembly 70 with the air cavity between the air outlet trough plate 12 and the base 10, forming an air outlet channel for the fan assembly 70. The air inlet of the fan assembly 70 is connected to the airflow hole 272 through a pipe, thereby connecting to the air outlet at the bottom of the sewage tank 40. This creates a wastewater recovery path from the cleaning brush head 2 - connecting hose 50 - L-shaped bend 23 - wastewater hole 271 - wastewater outlet 42 - wastewater pipe 44 - wastewater tank 40, and an airflow path from the cleaning brush head 2 - connecting hose 50 - L-shaped bend 23 - wastewater hole 271 - wastewater outlet 42 - wastewater pipe 44 - wastewater tank 40 - air outlet pipe 45 - airflow outlet 43 - airflow hole 272 - fan assembly 70 - arc-shaped air hole 13 - air cavity between air outlet trough plate 12 and base 10 - air outlet mesh 11. Under the action of the fan assembly 70, wastewater and debris from the surface of the fabric product are drawn into the wastewater tank 40, and the drawn-in air is expelled. A filter sponge 46 is installed inside the airflow outlet 43 to prevent wastewater and debris from entering the fan assembly 70 through the airflow path and affecting the operation of the fan.
[0034] A further configuration includes an annular mounting groove 121 and an air inlet groove 122 extending into the annular mounting groove 121 on the top surface of the air outlet duct plate 12.

The inner end of the air inlet housing 73 is connected to the inner hole of the annular partition 72, and the outer end is connected to a vertical air duct 74. The top end of the vertical air duct 74 is connected to the air outlet at the bottom of the sewage tank 40. This allows air from the sewage tank 40 to be drawn into the air inlet channel through the vertical air duct 74, and then through the inner hole of the annular partition 72 to the air inlet end of the turbine fan. Several air outlet holes 75 are provided on the annular partition 72, avoiding the air inlet housing 73, so that the air outlet holes 75 are connected to the air outlet channel. The arc-shaped air hole 13 is located at the air outlet end of the fan assembly 70, that is, in the area between the fan housing 71 and the air inlet housing 73, that is, at the location where the air outlet trough plate 12 is located in the area of the air outlet channel. This allows the air outlet channel to be connected to the air cavity at the bottom of the air outlet trough plate 12 through the arc-shaped air hole 13, thereby discharging air.
[0035] During setup, an L-shaped baffle 14 is provided protruding downwards from the bottom surface of the air outlet duct plate 12, arranged along the edge of the arc-shaped air hole 13. A row of arc-shaped air guide plates 15 are arranged at intervals on the bottom surface of the air outlet duct plate 12 between the L-shaped baffle 14 and the air outlet mesh 11. The airflow direction is adjusted by the L-shaped baffle 14 and the arc-shaped air guide plates 15, so that the airflow is turned after passing through the L-shaped baffle 14 and then guided by the arc-shaped air guide plates 15, making the airflow more uniform and stable, reducing the intensity of airflow turbulence and eddies, thereby reducing noise during operation and improving the user experience.
[0036] A fan housing 80 is provided on the top of the fan housing 71. A cooling fan (not shown in the figure) is provided inside the fan housing 80. The cooling fan is used to dissipate heat from the fan assembly 70 to prevent local overheating caused by prolonged operation of the fan assembly 70. A sealing partition 16 is provided on the bottom surface of the air outlet slot plate 12 on the side away from the arc-shaped air guide plate 15 of the L-shaped baffle 14. The sealing partition 16 divides the air cavity between the air outlet slot plate 12 and the base 10 into two cavities. An air inlet pipe 17 is provided on the air outlet slot plate 12, which communicates with the cavity away from the L-shaped baffle 14 of the sealing partition 16. The top end of the air inlet pipe 17 is connected to the air inlet end of the cooling fan. An air inlet mesh 18 is provided on the base 10 corresponding to the cavity on this side. The air inlet mesh 18 and the air inlet pipe 17 form the air intake passage for the cooling fan.
