[0032] like Figure 1As shown, the second wireless communication module transmits the signals input by the first button 202 and / or the second button 203 to the first wireless communication module. The first wireless communication module receives and outputs signals to drive the control circuit to control the operation of the steam component 101 and / or the suction component 102, spraying steam or clean water to clean stains and recycle wastewater.

[0033] like Figure 1 , Figure 4 As shown, the steam assembly 101 includes a water pump 104 and a steam generator 105, the suction assembly 102 includes an exhaust fan 108, and the main unit 100 is also equipped with an air pump 106. The control circuit on the first PCB board 103 controls the start-up and operation of the water pump 104, the steam generator 105, the air pump 106 and the exhaust fan 108 respectively.

[0034] like Figure 3 , Figure 6 As shown, the first button 202 is used to start the operation of the blower 108 to suck up the sewage on the fabric products, and the second button 203 is used to start the operation of the water pump 104, the steam generator 105 and the air pump 106 to spray water vapor or clean water from the brush head 201.

[0035] like Figure 6 As shown, the handle 200 is equipped with a battery 205, which powers the second wireless communication module in the second PCB board 204 on the handle 200.

[0036] In some embodiments, the signal transmission between the first wireless communication module and the second wireless communication module can be one of the short-range wireless data transmission methods such as Wi-Fi, Bluetooth, infrared, and ZigBee. For example, Wi-Fi uses wireless radio frequency technology to send and receive data signals; when transmitting via Bluetooth, the wireless communication module integrates a Bluetooth chip; when transmitting via infrared, the wireless communication module integrates an infrared transmitter and an infrared receiver.

[0037] like Figure 2As shown, this embodiment uses 2.4GHz wireless transmission. The second wireless communication module includes chip U1 and wireless transceiver chip IC1. Chip U1's general-purpose input / output pins 6 and 7 are connected to buttons SW1 and SW2, which are the first button 202 and the second button 203, used to input button signals. The signal connections between the pins of chip U1 and wireless transceiver chip IC1 are SDA, SCL, and CS, respectively, where SDA is the data signal, SCL is the clock signal, and CS is the trigger signal. The SPI communication protocol is used for transmission. Pins 1 and 2 of wireless transceiver chip IC1 are connected to a crystal oscillator, and pin 3 is connected to... The grounding point, pin 4 is the wireless signal transceiver pin connected to the antenna ANT. A capacitor C4 is connected between the antenna ANT and the wireless signal transceiver pin, and a capacitor C3 is connected between the antenna ANT and the grounding point. The wireless transceiver chip IC1 is used for receiving and transmitting wireless signals. Similarly, the first wireless communication module is the same as the second wireless communication module. In the first wireless communication module, the general-purpose input / output pins of the chip U1 are connected to the control chip in the first PCB board 103 for signal output. The second wireless communication module transmits wireless signals to the first wireless communication module. The second wireless communication module wirelessly transmits the button signals to the first wireless communication module.

[0038] Furthermore, in this embodiment, the wireless transceiver chip IC1 is an XF2400 wireless transceiver chip.

The chip integrates functional modules such as RF transceiver, frequency transceiver, crystal oscillator, and modem, and supports one-to-many networking and communication mode with ACK. In other embodiments, wireless transceiver chips with the same functions can also be used.

[0039] like Figure 4 , Figure 11 As shown, the steam assembly 101 includes a water pump 104 and a steam generator 105. The main unit 100 is equipped with an air pump 106. The clean water tank 300 is plugged into the main unit 100. The outlet 113 of the socket 111 of the clean water tank 300 and the input terminal of the steam generator 105 are connected to the water pump 104 and the air pump 106, respectively. The water pump 104 is connected to the clean water tank 300. The water pump 104 delivers the clean water in the clean water tank 300 to the steam generator 105 for heating. The air pump 106 delivers compressed air to the steam generator 105. The steam generator 105 outputs water vapor and / or clean water through the liquid outlet pipe (not shown) in the connecting pipe 500 to the handle 200 and then sprays it out from the brush head 201 to clean stains on fabric products.

[0040] In this embodiment, the fabric cleaning machine can spray cleaning steam to clean fabric products. The high-temperature steam accelerates the movement of molecules on the dirt surface, thereby breaking the binding force between them to eliminate various stubborn stains. At the same time, it completely eliminates various bacteria, mites, microorganisms and pathogens attached to the object, resulting in a better cleaning effect. It can also spray clean water when needed, and output clean water by turning off the steam generator 105.

[0041] like Figure 11 , Figure 12 As shown, the main unit 100 is also equipped with a three-way pipe 107. The three ports of the three-way pipe 107 are respectively connected to the water pump 104, the air pump 106 and the steam generator 105. The water pump 104 outputs clean water to the steam generator 105 through the three-way pipe 107, and the air pump 106 outputs compressed air to the steam generator 105 through the three-way pipe 107, thereby increasing the pressure of the water vapor and / or clean water in the steam generator 105 and outputting it to the handle 200.

[0042] like Figure 5 , Figure 10 As shown, the main unit 100 is equipped with a socket 111, and the clean water tank 300 is plugged into the main unit 100 through the socket 111. The socket 111 has an integrally formed top post 112, and a water outlet 113 is provided next to the top post 112. A filter screen 114 is provided above the water outlet 113 and around the top post 112. A sealing soft rubber gasket 115 is provided inside the socket 111. The sealing soft rubber gasket 115 opens when the clean water tank 300 is inserted and closes when the clean water tank 300 is pulled out to prevent foreign objects from falling into the socket 111 and keep the clean water of the fabric washing machine clear.

[0043] like Figure 5 , Figure 10 As shown, the bottom of the clean water tank 300 is provided with a top valve assembly 301. When the clean water tank 300 is inserted into the socket 111, the top column 112 opens the top valve assembly 301, allowing clean water in the clean water tank 300 to flow into the socket 111 and out through the filter screen 114 to the outlet 113. The top valve assembly 301 includes a movable block 302, a spring 303, and a sealing gasket 304. The sealing gasket 304 is located above the movable block 302, and the spring 303 is located between the bottom of the movable block 302 and the bottom wall of the clean water tank 300. When the top valve assembly 301 is opened, the movable block 302 rises against the elastic force of the spring 303 to open the sealing gasket 304, thus opening the water flow channel. When the top valve assembly 301 is closed, the elastic force of the spring 303 drives the movable block 302 downward to seal the sealing gasket 304 and seal the water flow channel.

[0044] The suction assembly 102 includes a blower 108 and a seal 109. The blower 108 is connected to the wastewater tank 400 via the seal 109. Figure 8The sewage tank 400 has a first connecting pipe 401 and a second connecting pipe 402 formed inside. The first connecting pipe 401 is connected to the outlet pipe 110 on the main unit 100. The outlet pipe 110 is connected to the connecting pipe 500. The second connecting pipe 402 is connected to the sealing element 109. After the blower 108 is started, a negative pressure is generated in the water tank, so that the connecting pipe 500, the handle 200 and the brush head 201 all form a negative pressure. The brush head 201 sucks up the sewage formed after cleaning the fabric products and draws the sewage into the sewage tank 400.

[0045] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
