In the embodiment of the invention, the abutting portions 2132 are hook-shaped, the number of the abutting portions 2132 is multiple, the distance between two oppositely arranged abutting portions 2132 is smaller than the outer diameter of the second limiting portion 2142, and the hook-shaped abutting portion 2132 has an inclined surface which can help the second limiting portion 2142 of the first water gas channel 214 to cross the abutting portion 2132, so that the first water gas channel 214 is completely located in the space formed by the accommodating portion 2131 and the abutting portions 2132.

In the embodiment of the present invention, the connection mechanism 20 may further include an anti-separation element 23, the anti-separation element 23 is connected to the first water gas channel 214, one end of the anti-separation element 23 extends into the cavity of the first water gas channel 214, and one end of the anti-separation element 23 extending into the cavity abuts against the second connection element 22 to limit the second connection element 22 from separating from the first connection element 21.

In an embodiment of the present invention, referring to fig. 3, which shows a schematic structural diagram of the anti-slip element 23 in the embodiment of the present invention, an end of the anti-slip element 23 extending into the cavity includes a first inclined surface 231 and a second inclined surface 232 which intersect with each other. The first inclined surface 231 faces the first end 2143 of the first moisture channel 214, the second inclined surface 232 faces the second end 2144 of the first moisture channel 214, and the slope of the second inclined surface 232 is greater than the slope of the first inclined surface 231, wherein the included angle between the first inclined surface 231 and the horizontal line L is α, the included angle between the second inclined surface 232 and the horizontal line L is β, and α < β.

In a specific implementation, the anti-slip element 23 may further include a bearing portion 233, where the bearing portion 233 is located outside the first water gas channel 214 and is used for bearing the anti-slip element 23 to prevent the anti-slip element 23 from sliding into the first water gas channel 214.

In the embodiment of the present invention, the number of the anti-slip elements 23 may be multiple and are circumferentially arranged on the first water gas channel 214. The anti-release members 23 may be uniformly circumferentially arranged in the first water vapor passage 214, or may be non-uniformly circumferentially arranged in the first water vapor passage 214. Because the slope of the first inclined plane 231 is slower than the slope of the second inclined plane 232, when the second connecting piece 22 is installed on the first connecting piece 21, the second connecting piece 22 is easily pushed into the first connecting piece 21, and after the first connecting piece 21 is pushed into the second connecting piece 22, the second connecting piece 22 can be blocked because the slope of the second inclined plane 232 is larger, the position of the second connecting piece 22 is limited, and the second connecting piece 22 is not easy to fall off from the first connecting piece 21.

In the embodiment of the present invention, the retaining member 23 has elasticity and can be elastically deformed.

With continued reference to fig. 1 and 2, in an implementation, the first water passage 214 may include a first portion and a second portion along a direction from the first end 2143 to the second end 2144 of the first water passage 214, wherein the first portion and the second portion are both located between the first position-limiting portion 2141 and the second position-limiting portion 2142. The first portion may include a first annular tapered surface 2145, and an outer diameter of the first annular tapered surface 2145 gradually increases from the first end 2143 to the second end 2144 of the first water/gas passage 214.

The second portion has an outer diameter smaller than the maximum outer diameter of the first portion, and is provided with a first notch 2148 for connecting the anti-slip member 23. After the first water and gas passage 214 moves relative to the outer slide ring 215 in the direction from the second end 2152 to the first end 2151 of the outer slide ring 215, the outer diameter of the first annular tapered surface 2145 gradually increases from the first end 2143 to the second end 2144 of the first water and gas passage 214 may be pushed against the first annular tapered surface 2145 by the inner wall of the outer slide ring 215, and the first water and gas passage 214 may be pushed to move in the direction from the first end 2151 to the second end 2152 of the outer slide ring 215 by pushing the first annular tapered surface 2145 to move in the direction from the first end 2151 to the second end 2152 of the outer slide ring 215, so that the position of the first water and gas passage 214 and the outer slide ring 215 may return to the initial position.

In an embodiment of the present invention, the size of the bearing portion 233 is smaller than that of the first notch 2148, so that the anti-slip part 23 can be partially located outside the first water vapor channel 214 and partially extend into the first water vapor channel 214, and the anti-slip part 23 is borne on the first water vapor channel 21, thereby preventing the anti-slip part 23 from falling into the cavity of the first water vapor channel 214 from the first notch 2148.

The inner diameter of the first end 2151 of the out-of-channel slip ring 215 is smaller than the inner diameter of the second end 2152 of the out-of-channel slip ring 215, and the inner diameter of the other portion 2154 located between the first end 2151 of the out-of-channel slip ring 215 and the second end 2152 of the out-of-channel slip ring 215 is larger than the inner diameter of the second end 2152 of the out-of-channel slip ring 215.

In a specific implementation, the retaining member 23 is located outside the channel within the slip ring 215. The initial position of the anti-slip element 23 outside the passage 215 corresponds approximately to the second end 2152 of the out-of-passage slip ring 215. Wherein the initial position refers to when the first connecting member 21 and the second connecting member 22 are in the unconnected state.

When the second connecting member 22 is pulled out from the first connecting member 21, since the anti-release member 23 abuts against the second connecting member 22, the anti-release member 23 is driven by the second connecting member 22 to move from the second end 2152 of the out-of-channel slide ring 215 toward the first end 2151, and since the inner diameter of the other portion 2154 of the out-of-channel slide ring 215 is larger than the inner diameter of the second end 2152, when the position of the other portion 2154 is reached, under the action of the second connecting member 22, the second connecting member 22 gives the anti-release member 23 a force in a direction away from the central axis of the first water and air channel 214 along the radial direction, so that the anti-release member 23 is away from the first water and air channel 214 and moves toward the inner wall of the out-of-channel slide ring 215 to release the restriction of the second connecting member 22, and the second connecting member 22 can be pulled out from the first connecting member 21.

The inner diameter of the first end 2151 of the outer channel sliding ring 215 decreases in a direction away from the second end 2152 of the outer channel sliding ring 215, and the first end 2151 of the outer channel sliding ring 215 is divided into a plurality of segments 2153 along the circumferential direction, so that the elasticity of the first end 2151 of the outer channel sliding ring 215 can be improved, and since the outer diameter of the first limiting portion 2141 of the first water and gas channel 214 is larger than the inner diameter of the first end 2151 of the outer channel sliding ring 215, when the first water and gas channel 214 is installed on the outer channel sliding ring 215, the first end 2151 of the outer channel sliding ring 215 is easily separated by the first limiting portion 2141, so that the first limiting portion 2141 can smoothly pass over the first end 2151 of the outer channel sliding ring 215. After the first limiting portion 2141 passes over the outer channel sliding ring 215, the first end 2151 of the outer channel sliding ring 215 is restored to the original state from the expanded state, and at this time, the first limiting portion 2141 is located outside the outer channel sliding ring 215, and the first limiting portion 2141 abuts against the end surface of the first end 2151 of the outer channel sliding ring 215.

Referring to fig. 1, 2 and 6, the first connecting member 21 further includes a first sealing ring 218 sleeved at the second end 2144 of the first water gas channel 214, and the first sealing ring 218 can improve the sealing performance between the second end 2144 of the first water gas channel 214 and the water pipe 81, so as to prevent water gas from leaking.

In order to facilitate a better understanding of the connection mechanism 20, referring to fig. 6 to 15, a schematic diagram of the relative positions of the first connection member 21 and the second connection member 22 of the connection mechanism 20 during the connection process or the extraction process is shown, and the working principle of the connection mechanism 20 will be described below with reference to fig. 1 to 17.

Referring to fig. 6, a schematic diagram of the relative positions of the first connecting member 21 and the second connecting member 22 when they are not installed in the embodiment of the present invention is shown. The second end 2144 of the first moisture passage 214 is connected to the water pipe 81, and is connected to the water system of the laundry device 100 through the water pipe 81. The first outlet 211 is a four-core jack and is connected to the electric system 70 of the laundry apparatus 100 through the electric cord 91.

The second end 2232 of the second moisture passage 223 is connected to the water pipe 82, and is connected to the expansion device 10 through the water pipe 82.

Referring to fig. 7, a schematic diagram of the relative positions of the first connecting member 21 and the second connecting member 22 in the installation process in the embodiment of the present invention is shown, and fig. 8 is a partial enlarged view at I of fig. 7. The first end 2143 of the first water gas channel 214 has an inner diameter larger than an outer diameter of the first end 2231 of the second water gas channel 223 when the second connector 22 is inserted into the first connector 21. As the second water gas channel 223 moves toward the first water gas channel 214, after reaching the position of the anti-slip member 23, the effective space of the first water gas channel 214 is reduced because the anti-slip member 23 extends into the first water gas channel 214, and the second annular tapered surface 2233 of the first end 2231 of the second water gas channel 223 touches the first inclined surface 231 of the anti-slip member 23. Since the slope of the first inclined surface 231 is gentle and cooperates with the second annular tapered surface 2233, the second annular tapered surface 2233 is helped to pass over the anti-slip member 23. After the second annular tapered surface 2233 passes over the anti-slip part 23, the abutting surface 2238 of the second annular tapered surface 2233 and the second inclined surface 232 abut against each other, which can be seen in fig. 9, which is a schematic diagram of the relative positions of the first connecting part 21 and the second connecting part 22 after the installation of the first connecting part 21 and the second connecting part 22 in the embodiment of the present invention, and fig. 10, which is a partially enlarged view of the point P in fig. 9.

In the embodiment of the present invention, the second annular tapered surface 2233 protrudes from the second water channel 223 to form an abutting surface 2238.

The abutting surface 2238 of the second annular tapered surface 2233 and the second inclined surface 232 abut against each other, so that water or steam is prevented from leaking when the water or steam is transmitted from the first water gas channel 214 to the second water gas channel 223.

The second input port 221 may be inserted along the second output port 212. For example, second output port 212 is a quad-core receptacle and second input port 221 is a quad-core plug with metal pins. The pin of the four-core plug is inserted into the groove of the four-core socket.

Referring to fig. 11, there are shown a schematic view of the relative position of the first connecting member 21 when it is pulled out from the second connecting member 22 in the embodiment of the present invention, and an enlarged partial view at Q of fig. 11 shown in fig. 12. When the second connecting member 22 is pulled out from the first connecting member 21, due to the larger gradient of the second inclined surface 232 of the anti-slip member 23, the second annular tapered surface 2233 of the second water gas passage 223 drives the anti-slip member 23, and the anti-slip member 23 drives the first water gas passage 214 to move toward the first end 2151 of the out-passage sliding ring 215.

Referring to fig. 13, the relative position of the first connecting member 21 when it is pulled out from the second connecting member 22 in the embodiment of the present invention is schematically illustrated. Fig. 14 is a partial enlarged view at M of fig. 13. The inner diameter increases as it travels along other portions 2154 due to the direction of the outer-channel ring 215 from the second end 2152 to the first end 2151, where the other portions 2154 refer to the portion of the outer-channel ring 215 between the first and second ends 2151 and 2152. When the anti-slip element 23 is located at the second end 2152 of the out-of-channel sliding ring 215, the anti-slip element 23 abuts against the inner wall of the out-of-channel sliding ring 215, and when the anti-slip element 23 is located at a position corresponding to the other portion 2154 of the out-of-channel sliding ring 215, because the inner diameter of the other portion 2154 is larger than the inner diameter of the second end 2152, the second connecting element 22 is pulled, the second annular tapered surface 2233 gives the anti-slip element 23 a force that causes the anti-slip element 23 to disengage from the first water gas channel 214, and after the anti-slip element 23 moves away from the first water gas channel 214, the anti-slip element 23 can release the restriction on the second annular tapered surface 2233, so that the second connecting element 22 can be pulled out of the first connecting element 21, see fig. 15.

The second input port 221 may be pulled out along the second output port 212. For example, second output port 212 is a quad-core receptacle and second input port 221 is a quad-core plug with metal pins. The pin of the four-core plug is pulled out from the groove of the four-core socket.

In an embodiment of the present invention, each inlet may include a solenoid valve, which may be controlled to open or close by a control program of the laundry device 100 to select which inlet is open to meet the demand of water or steam output from the first output port 211.

For example, when the extension device 10 is a hand-held garment steamer, and the first output port 211 needs to output steam, the solenoid valve arranged in the inlet connected to the steam generating device 40 is opened, the solenoid valve arranged in the inlet connected to the water inlet valve 61 is closed, and the steam generating device 40 is controlled to be opened, so that the steam generated by the steam generating device 40 is output from the first output port 211 through the three-way valve 64.
