[0043] Please refer to Figures 1 to 3According to the first aspect of the embodiment of the utility model, the quick connection mechanism for the steam ablation liquid path connecting tube includes a connecting shell cover 1, an inner sleeve 2, a pressing sleeve 3 and an elastic member 4. The connecting shell cover 1 is provided with a liquid path channel 11; the inner sleeve 2 is inserted into the liquid path channel 11, and the inner sleeve 2 forms an installation channel 21; the pressing sleeve 3 can be movably inserted into the installation channel 21, and the pressing sleeve 3 forms a pipeline channel 31; the elastic member 4 is arranged on the inner wall of the installation channel 21, and the elastic member 4 is enclosed to form an aisle. The elastic member 4 has an initial state and an expanded state. In the expanded state, the pressing sleeve 3 is inserted into the installation channel 21 and passes through the aisle to abut against the expanded elastic member 4. When the pressing sleeve 3 withdraws from the aisle, the elastic member 4 has a tendency to return to the initial state.

[0044] According to the quick connection mechanism for the steam ablation liquid circuit connecting tube of the embodiment of the utility model, the inner sleeve 2 is inserted into the liquid cooling channel of the connecting shell cover 1, and the inner sleeve 2 is formed with an installation channel 21 to install the press sleeve 3. In addition, a pipeline channel 31 is formed in the press sleeve 3 for the liquid circuit connecting tube 7 to pass through. When the press sleeve 3 is inserted into the installation channel 21 of the inner sleeve 2, the press sleeve 3 gradually passes through the passage formed by the elastic member 4 to open the passage of the elastic member 4. At this time, the liquid circuit connecting tube 7 can be inserted into the pipeline channel 31 of the press sleeve 3 and pass through the passage of the elastic member 4. At the same time, the press sleeve 3 can move relative to the inner sleeve 2. After the liquid circuit connecting tube 7 passes through the passage of the elastic member 4, the press sleeve 3 can be withdrawn from the passage. At this time, the elastic member 4 is no longer opened by the press sleeve 3, so that the elastic member 4 gradually recovers to the initial state, thereby shrinking the passage until the elastic member 4 abuts against the outer tube wall of the liquid circuit connecting tube 7, so that the liquid circuit connecting tube 7 is firmly installed. In this way, the liquid connection pipe 7 is quickly connected and the installation is convenient.

[0045] Please refer to Figure 5 and Figure 10 It can be understood that the liquid channel 11 of the connecting shell cover 1 is used to install the liquid connecting pipe 7. In order to make the two quickly and stably connected, the inner sleeve 2 and the compression sleeve 3 are mutually sleeved and inserted in the liquid channel 11. When the liquid connecting pipe 7 is inserted, the outer wall of the liquid connecting pipe 7 is fixed by the elastic member 4 to achieve the installation of the liquid connecting pipe 7. It should be noted that the liquid channel 11, the installation channel 21 and the pipeline channel 31 are coaxially arranged for the liquid connecting pipe 7 to pass through.

[0046] The elastic member 4 can be a spring sheet, an elastic rod, or a shrinkable and expandable elastic ring, etc., which is not limited here, as long as it can be stretched by the pressing sleeve 3 and can elastically restore to its initial state after the pressing sleeve 3 is away from the elastic member 4. For example, the elastic member 4 is two elastic sheets arranged opposite to each other, the two elastic sheets are respectively connected to the inner wall of the installation channel 21, and a passage is formed between the two elastic sheets. The two elastic sheets expand or reduce the passage by deformation to abut against and clamp the liquid path connecting tube 7.

[0047] like Figure 11 As shown, it should be noted that the liquid connection tube 7 is generally a soft rubber tube, and the outer wall of the liquid connection tube 7 is suitable for being concave inward under the elastic extrusion of the elastic member 4, that is, the tube wall of the liquid connection tube 7 is partially deformed and concave when in contact with the elastic member 4, so that the elastic member 4 is buckled against the tube wall of the liquid connection tube 7, and the liquid connection tube 7 is not easy to be separated from the liquid channel 11 in the opposite direction of its insertion direction, and the installation is more secure. In other embodiments, a clamping groove can also be set at the corresponding position of the liquid connection tube 7, and when the elastic member 4 rebounds, it abuts against the clamping groove to prevent the liquid connection tube 7 from exiting the liquid channel 11.

[0048] like Figure 3 As shown, according to an embodiment of the present invention, the elastic member 4 includes a plurality of inner card spring pieces, and the plurality of inner card spring pieces are arranged around the inner wall of the installation channel 21 , and one end of each inner card spring piece is connected to the inner wall of the installation channel 21 .

[0049] Exemplarily, the inner wall of the installation channel 21 is provided with a mounting platform, one end of the inner card spring is connected to the mounting platform, and the other end extends into the installation channel 21 to abut against the pressing sleeve 3 or the liquid connection pipe 7. A plurality of inner card springs are arranged in a ring shape at intervals to abut against the circumference of the liquid connection pipe 7, so that the installation is more stable. In other words, a plurality of inner card springs are arranged in a ring shape, and a passage is formed in the middle for the pressing sleeve 3 or the liquid connection pipe 7 to pass through.

[0050] According to an embodiment of the utility model, each inner card spring is arranged at a right angle or an acute angle to the inner wall of the installation channel 21 in the direction away from the opening of the liquid path channel 11. Exemplarily, the inner card spring is arranged at an acute angle to the inner wall of the installation channel 21, that is, a plurality of inner card springs are enclosed in the insertion direction of the pressing sleeve 3 to form a funnel shape, so that the pressing sleeve 3 can be easily inserted into the aisle for easy installation. At the same time, when the pressing sleeve 3 withdraws from the aisle, a plurality of inner card springs are funnel-shaped, so that the liquid path connecting tube 7 can continue to move in the insertion direction, and when the liquid path connecting tube 7 is pulled out in the opposite direction of the insertion direction, the inner card spring is connected to the outer wall of the liquid path connecting tube 7 to prevent the liquid path connecting tube 7 from being separated from the liquid path channel 11, thereby realizing the rapid installation and connection of the liquid path connecting tube 7.

[0051] It should be noted that when it is necessary to remove and pull out the liquid connection tube 7, the pressing sleeve 3 can be moved again through the passage to open the multiple inner card springs again, so that the multiple inner card springs are separated from the contact with the liquid connection tube 7, so that the liquid connection tube 7 can be smoothly pulled out. In other words, the pressing sleeve 3 plays an auxiliary role to achieve the locking and unlocking of the liquid connection tube 7 and the elastic member 4.

[0052] Please refer to Figure 5 and Figure 8According to an embodiment of the utility model, the pressing sleeve 3 includes a penetration portion 32 and a limiting portion 33. At least a portion of the penetration portion 32 is penetrated in the installation channel 21, and the penetration portion 32 forms a first channel; the limiting portion 33 is connected to one end of the penetration portion 32, and the limiting portion 33 is used to stop and abut against the outer wall of the inner sleeve 2 or the outer wall of the connecting shell cover 1, and the limiting portion 33 forms a second channel. The first channel and the second channel are connected to form a pipeline channel 31. It can be understood that the penetration portion 32 is penetrated in the installation channel 21 and is used to prop open the elastic member 4. The limiting portion 33 is located outside the installation channel 21, so that the staff can grasp and operate it, and the limiting portion 33 can abut against the outer wall of the inner sleeve 2 or the outer wall of the connecting shell cover 1 to prevent the pressing sleeve 3 from entering the installation channel 21 as a whole. Optionally, the penetration portion 32 and the limiting portion 33 are integrally formed to reduce the installation steps and improve the connection stability. The first channel and the second channel are coaxially arranged, so as to be connected to form a pipeline channel 31, which is convenient for the installation of the liquid connection pipe 7.

[0053] According to an embodiment of the utility model, the outer peripheral wall of the penetration portion 32 is provided with a limiting groove 321, and the limiting groove 321 extends at least in the axial direction of the penetration portion 32. The inner wall of the installation channel 21 is provided with a convex protrusion 23, and the convex protrusion 23 can be slidably engaged in the limiting groove 321. In this embodiment, the limiting groove 321 can surround along the circumference of the penetration portion 32, and the convex protrusion 23 can be an annular convex protrusion 23, so as to surround and abut against the groove wall of the limiting groove 321, so as to ensure that the circumferential force of the penetration portion 32 is uniform. The limiting groove 321 extends in the axial direction of the penetration portion 32, so that the pressing sleeve 3 can be inserted and pulled out relative to the inner sleeve 2 in the axial direction, so as to realize the passage of the pressing sleeve 3 through the elastic member 4 or exit the passage. At the same time, the groove wall of the limiting groove 321 on one side located in the installation channel 21 can be used as a stop surface, and the stop surface can be abutted with the convex protrusion 23 to prevent the pressing sleeve 3 from completely detaching from the installation channel 21, so as to avoid the loss of the pressing sleeve 3.

[0054] According to an embodiment of the utility model, a guide slope 322 is provided on the outer peripheral wall of one end of the penetration portion 32 away from the limiting portion 33. The guide slope 322 is inclined close to the first channel in a direction away from the limiting portion 33, and is used to abut the elastic member 4.

[0055] In order to facilitate the pressing sleeve 3 to pass through the passage, the end of the penetration portion 32 away from the limiting portion 33 is set to a gradually pointed shape, that is, the penetration portion 32 is gradually guided to pass through the passage through the guide slope 322, thereby gradually expanding the elastic member 4. In other words, the outer diameter of one end of the penetration portion 32 gradually decreases in the direction away from the limiting portion 33, and the pressing sleeve 3 is more easily inserted through the passage.

[0056] Please refer to Figure 6 and Figure 7, according to an embodiment of the present utility model, a clamping groove 12 is provided in the liquid passage 11, and the inner sleeve 2 is provided with a clamping buckle 22. When the inner sleeve 2 is inserted into the liquid passage 11, the clamping buckle 22 is in clamping fit with the clamping groove 12. It can be understood that the inner sleeve 2 is connected to the connection shell cover 1 by means of the clamping buckle 22, and the installation can be completed without other connecting parts or installation tools, which is convenient for operation. Exemplarily, a plurality of clamping grooves 12 are provided around the liquid cooling passage, and a plurality of clamping buckles 22 are correspondingly provided on the outer peripheral wall of the inner sleeve 2. The plurality of clamping buckles 22 are in clamping fit with the plurality of clamping grooves 12 to improve the connection stability. In other embodiments, the clamping groove 12 can also be a clamping hole, as long as the clamping buckle 22 can be clamped to the connection shell cover 1, which is not limited herein.

[0057] Please refer to Figures 5 to 7 , according to an embodiment of the present utility model, a step surface 13 is convexly provided on the inner wall of the liquid passage 11. The quick connection mechanism for the steam ablation liquid passage connecting pipe further includes a sealing ring 5, and the sealing ring 5 is provided on the step surface 13 and is in sealing contact with one end of the inner sleeve 2.

[0058] It can be understood that one side of the sealing ring 5 is in sealing contact with the step surface 13, and the other side is in sealing contact with one end of the inner sleeve 2 to prevent the liquid in the liquid passage connecting pipe 7 from leaking out from the connection gap between the inner sleeve 2 and the connection shell cover 1. At the same time, the liquid passage connecting pipe 7 passes through the sealing ring 5, or the outer wall surface of the liquid passage connecting pipe 7 adjacent to its outlet end is in sealing contact with the sealing ring 5 to prevent liquid leakage.

[0059] Please refer to Figure 2 and Figure 6 , according to an embodiment of the present utility model, the connection shell cover 1 is provided with two liquid passages 11, and each liquid passage 11 is correspondingly provided with a set of inner sleeve 2, pressing sleeve 3 and elastic member 4. That is to say, the connection shell cover 1 can be used to connect two liquid passage connecting pipes 7 to form a double-channel structure, improving the infusion efficiency.

[0060] Please refer to Figures 9 to 11 , according to an embodiment of the second aspect of the present utility model, the steam ablation device includes a body 6, a liquid passage connecting pipe 7 and the above-mentioned quick connection mechanism for the steam ablation liquid passage connecting pipe.
