[0031] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0032] See Figures 1 to 8 As shown in the figure: The disassembly and connection structure includes a brush head 1, and a first pipeline 11 and a second pipeline 12 for conducting steam and sewage are arranged in the brush head 1; a quick-release clamping module 2, and the quick-release clamping module 2 is coaxially and fixedly arranged in the first pipeline 11; a connecting and fixing module 3, and the connecting and fixing module 3 is coaxially and detachably arranged at the connecting end of the quick-release clamping module 2, and the connecting and fixing module 3 is provided with a third pipeline 31 and a fourth pipeline 32 respectively cooperating with the first pipeline 11 and the second pipeline 12; a pressure-changing opening and closing module 4, and the pressure-changing opening and closing module 4 is coaxially and fixedly arranged in the third pipeline 31, and the pressure-changing opening and closing module 4 is provided with a first air inlet channel 421 capable of conducting steam and a sealing opening and closing rod 41 capable of axially sliding in the first air inlet channel 421 under a rated pressure; when there is no external force, the first air inlet channel 421 is closed via the sealing opening and closing rod 41, and when there is an external force, the first air inlet channel 421 is opened via the sealing opening and closing rod 41; a transmission hose 5, and the transmission hose 5 is detachably arranged at the connecting end of the connecting and fixing module 3.

[0033] When it is necessary to achieve a quick connection between the fastening module 3 and the brush head 1, the staff first take the brush head 1 and the fastening module 3 respectively, and dock the first pipeline 11 with the third pipeline 31, and the second pipeline 12 with the fourth pipeline 32, ensuring accurate alignment of the pipelines to complete the insertion of the fastening module 3 into the brush head 1, so that fluid communication is achieved between the pipelines. During the insertion process of the brush head 1 and the fastening module 3, with the insertion force between the two, the front end of the sealing opening and closing rod 41 abuts against the access end of the quick-release clamping module 2. When the insertion force acts on the sealing opening and closing rod 41, the sealing opening and closing rod 41 retracts axially, thus opening the first air inlet passage 421 for steam transmission, enabling steam to smoothly enter the first pipeline 11 via the quick-release clamping module 2 and realizing the steam transmission function.

[0034] When the staff need to separate the fastening module 3 from the brush head 1, with the release of the insertion force, after the sealing opening and closing rod 41 loses the external force, it automatically resets under the action of the return spring force and closes the first air inlet passage 421, thus effectively preventing steam output and ensuring that steam leakage will not occur after the device is disconnected, avoiding the risk of scalding to the human body caused by continuous steam ejection.

[0035] Through the cooperation of the quick-release clamping structure and the sealing opening and closing rod 41, the quick insertion and automatic sealing between the brush head 1 and the fastening module 3 are realized, effectively improving the operation convenience of the device. The sealing opening and closing rod 41 automatically opens the steam channel during connection and automatically closes the steam flow during separation, ensuring safety during use and preventing steam leakage from scalding the user.

[0036] See Figure 4 and Figure 5 As shown: The pressure-changing opening and closing module 4 further includes a guiding unit 42 capable of axially guiding the sealing opening and closing rod 41 and a spring 43 capable of continuously applying an axial elastic force to the sealing opening and closing rod 41; the guiding unit 42 is coaxially and fixedly arranged in the third pipeline 31; the first air inlet passage 421 is coaxially and penetratingly opened in the guiding unit 42; and a limiting ring 422 capable of limiting the sealing opening and closing rod 41 after it slides to a preset stroke is coaxially arranged in the middle of the first air inlet passage 421; the spring 43 is coaxially arranged in the first air inlet passage 421, and one end of the spring 43 abuts against the inner wall of the first air inlet passage 421, and the other end abuts against the end of the sealing opening and closing rod 41.

[0037] When the sealing opening and closing rod 41 is in a non-working state, its side wall abuts against the limit ring 422 under the continuous pushing action of the spring 43. The inner diameter of the limit ring 422 is smaller than the inner diameter of the first air inlet channel 421, thereby effectively blocking the first air inlet channel 421 to prevent steam leakage. When the brush head 1 is plugged into the connection module 3, the front end of the sealing opening and closing rod 41 abuts against the connecting end of the quick-release card module 2 under the action of the plug-in force, and retracts axially under pressure during the force process, so that the sealing opening and closing rod 41 is away from the limit ring 422, thereby releasing the blockage of the first air inlet channel 421 and realizing steam circulation. At this time, the steam transported through the transmission hose 5 smoothly enters the first air inlet channel 421, and is further introduced into the first pipeline 11 through the quick-release card module 2, realizing effective steam transportation.

[0038] The guiding unit 42 is composed of a limiting portion 423 and a fixing portion 424; the fixing portion 424 is coaxially fixedly arranged in the third pipe 31; and a second air intake channel 4241 connected to the third pipe 31 is opened in the fixing portion 424; the limiting portion 423 is coaxially and detachably arranged at the connecting end of the fixing portion 424; the first air intake channel 421 is opened through the limiting portion 423 and is connected to the first air intake channel 421.

[0039] When the steam is transmitted, the steam is first introduced into the fixed portion 424 through the second air inlet channel 4241 and then conducted through the fixed portion 424, and then transmitted to the first air inlet channel 421 that passes through the opening in the limiting portion 423, thereby achieving orderly transmission of the steam.

[0040] See also Figure 8 As shown: the sealing opening and closing rod 41 is composed of a sliding rod 411 and a flange 412, a first sealing ring 413, a cone ring 414 and a guide ring 415 which are coaxially fixed on the outside of the sliding rod 411 in sequence; the flange 412 and the cone ring 414 are both arranged at one end of the sliding rod 411 close to the transmission hose 5; the first sealing ring 413 is embedded between the flange 412 and the cone ring 414 to abut against the limit ring 422; the guide ring 415 is coaxially arranged at the other end of the sliding rod 411 relative to the flange 412.

[0041] The outer diameters of the flange 412, the first sealing ring 413 and the cone ring 414 are all smaller than the inner diameter of the first air inlet passage 421, but larger than the inner diameter of the stop ring 422, so as to ensure that the sealing assembly has a stable guiding and positioning effect in the passage. At the same time, the outer diameter of the guide ring 415 is smaller than the inner diameter of the stop ring 422.

[0042] In a state without external force, the sealing opening and closing rod 41 moves axially towards the quick-release clamping module 2 under the continuous pushing action of the spring 43. During this process, the first sealing ring 413 is always in close contact with the side wall of the limiting ring 422 under the action of the spring 43 force, thereby effectively blocking the first air inlet channel 421 and preventing steam leakage. The guiding ring 415 provides a stable limiting and correction function during the axial sliding of the sealing opening and closing rod 41, ensuring that the sealing opening and closing rod 41 always maintains a stable movement in the axial direction during the sliding process, and avoiding sealing failure or unstable connection caused by deviation or inclination.

[0043] See Figure 7 As shown: The connecting and fixing module 3 further includes a main connector 33 capable of fixedly installing the first pipe 11 and the second pipe 12 respectively, and a movable buckle 34 capable of buckling the main connector 33 and the quick-release clamping module 2; the first pipe 11 and the second pipe 12 are oppositely arranged on one side of the main connector 33 and are both communicated with the main connector 33; the buckle 34 is movably hinged to the side wall of the main connector 33.

[0044] The buckle 34 is hinged and installed on the side wall of the main connector 33 through a torsion spring, so that it can adjust the angle under the action of external force and return to the initial position after releasing the external force.

[0045] After the brush head 1 is inserted into the connecting and fixing module 3, in order to prevent accidental separation of the two during use, further locking and buckling are required. During the insertion process, the staff only needs to press the buckle 34 to make its buckling end lift upward around the hinge point, thus avoiding interfering with the insertion operation. After the brush head 1 is inserted into the connecting and fixing module 3, release the buckle 34. At this time, the buckle 34 returns to its original position under the elastic force of the torsion spring and rotates and descends axially, so that its buckling end is tightly buckled with the preset buckle groove outside the brush head 1, realizing the automatic locking of the brush head 1 and the connecting and fixing module 3.

[0046] See Figure 8 As shown: The quick-release clamping module 2 is provided with a gas guiding rod 21 capable of conducting steam and a second sealing ring 22 capable of ensuring the plugging tightness in the plugged state.

[0047] The quick-release clamping module 2 further includes a connecting portion 23, which is radially fixedly arranged on both sides of the gas guiding rod 21 to ensure that the gas guiding rod 21 is firmly fixed in the first pipe 11 and prevent deviation or loosening. A ring groove 24 is provided on the outer wall of one end of the gas guiding rod 21 close to the sealing opening and closing rod 41 for embedding and installing the second sealing ring 22 to enhance the sealing performance.

[0048] When the staff inserts the brush head 1 into the connection and fixation module 3, the air guide rod 21 located in the first pipeline 11 will automatically be coaxially aligned with the first air intake channel 421 and continuously insert into the interior of the first air intake channel 421 along the axial direction under the action of the insertion force. As the insertion force increases, the end of the air guide rod 21 finally abuts against the end of the sealing opening and closing rod 41, causing the sealing opening and closing rod 41 to be compressed and retracted axially, thereby opening the first air intake channel 421 and realizing the smooth conduction of steam. In addition, since the outer wall of the air guide rod 21 is provided with a second sealing ring 22, during the process of the air guide rod 21 inserting into the first air intake channel 421, the second sealing ring 22 is closely attached to the inner wall of the channel, forming an effective sealing structure to prevent steam leakage and ensure the stability and tightness of steam transmission.

[0049] The fabric cleaning machine includes a disassembly and connection structure.

[0050] The utility model can not only realize the quick connection between the brush head and the cleaning machine, with a tight connection at the joint and good steam flowability after connection.
