The valve core sleeve 62 is provided with a valve core channel 62a for the valve core head 61 to block. The valve core channel 62a extends out of the valve core plug-in tube to be inserted into the valve core guide tube. The two ends of the valve core spring 63 respectively conflict with the valve core sleeve 62 and the upper fixed ring 3 to drive the valve core head 61 to block the valve core channel 62a.

[0031] The connecting rod 50 is preferably a screw, and the valve core head 61 is threadedly connected to the screw. The connecting portions 5 of the upper fixing ring 3 and the lower fixing ring 4 are both provided with through holes 51 for the screw to pass through, and at least the through hole 51 of the connecting portion 5 of the upper fixing ring 3 is provided with an internal thread adapted to the screw.

[0032] The upper fixing ring 3 and / or the lower fixing ring 4 are provided with a rotation limiting portion 53, and the positioning ring 21 is provided with a rotation limiting opening 211 adapted to the rotation limiting portion for insertion of the rotation limiting portion 53. This prevents the upper fixing ring 3 from rotating when the screw is tightened, allowing the upper fixing ring 3 and the lower fixing ring 4 to move toward each other and clamp the positioning ring 21. Preferably, both the upper fixing ring 3 and the lower fixing ring 4 are provided with a rotation limiting portion 53.

[0033] In order to facilitate the removal of the consumable box, a lifting mechanism is provided in the base shell 1 for pushing the consumable box out of the plug-in interface 1b. The lifting mechanism includes a support plate 71 for supporting and contacting the consumable box and a lifting bracket 72 for driving the support plate 71 to rise. The support plate 71 is provided with a conductive movable opening 711 for the consumable conducting tube 2 to pass through, so as to avoid the setting of the support plate 71 affecting the docking work of the consumable conducting tube 2.

[0034] Specifically, the lifting bracket 72 includes a bracket seat 721 and an elastic member 722 for driving the support plate 71 to rise. The bracket seat 721 is provided with a movable channel 7211 for mounting the elastic member 722. The support plate 71 is provided with a guide post 712 for guiding the lifting movement of the support plate 71. The guide post 712 is inserted into the movable channel 7211 to compress the elastic member 722. Therefore, when the plug-in end of the consumable cartridge is inserted, it presses down the support plate 71, thereby compressing the elastic member 722 and storing energy for lifting the support plate 71.

[0035] See also Figure 4 In order to maintain the compressed state of the elastic member 722 to prevent the consumable box from being pushed out again after being inserted, the lifting mechanism also includes a locking assembly for maintaining the compressed state of the elastic member 722 and a fixed locking seat 73 for installing the locking assembly. The fixed locking seat 73 is fixedly connected to the inner bottom surface of the base shell 1 to buckle the consumable box through the locking assembly to limit the support plate 71 from lifting the consumable box.

[0036] In detail, the consumable box is provided with a buckle hole, and the locking assembly includes a buckle head 74 for buckling into the buckle hole, a lateral movable rod 75 for manual pressing and driving, and a buckle spring 76 for laterally driving the buckle head 74 to buckle into the buckle hole. The fixed locking seat 73 is provided with a lateral locking guide hole 731 for guiding the lateral movable rod 75 to move laterally, and the lateral movable rod 75 is provided with a lateral movable guide column 751 adapted to the lateral locking guide hole 731.

[0037] The lateral movable rod 75 is provided with a spring mounting post 752 for mounting the buckling spring 76 . One end of the buckling spring 76 is sleeved on the spring mounting post 752 , and the other end thereof abuts against the side wall of the fixed locking seat 73 .

[0038] Therefore, under the action of the locking spring 76, the locking head 74 can stably lock the button hole. Accordingly, when the locking head 74 needs to be disengaged from the button hole, it is only necessary to press the lateral movable rod 75 to compress the locking spring 76, so that the elastic member 722 can release the elastic force and push the consumable box upward so that the user can take the consumable box.

[0039] Furthermore, there are at least two lateral movable guide columns 751, and the fixed locking seat 73 is provided with lateral locking guide holes 731 that match and correspond to the number of the lateral movable guide columns 751; wherein, at least one end of the lateral movable guide column 751 is provided with a limiting buckle head 7511, so that the limiting buckle head 7511 is buckled into the lateral locking guide hole 731 to limit the lateral movable guide column 751 from being disengaged from the lateral locking guide hole 731.

[0040] The base housing 1 includes a trunk housing, a top plate 11 and a bottom plate 12, which are combined to form a mechanism space for accommodating equipment components. The conducting port 1a is provided on the bottom plate 12, and the plug port 1b is provided on the top plate 11;

[0041] The trunk shell includes an access panel 13, a side panel 14 and a back panel 15 corresponding to the access panel 13. The side panels 14 are provided on both sides of the back panel 15. The side panels 14 and the back panel 15 are an integrated structure.

[0042] The top and bottom of the side panels 14 are each provided with flanges 141, connecting the top and bottom panels 11 and 12 to the trunk shell via these flanges 141. The side panels 14 are also provided with side flanges 142 for connection to the access panel 13. The inner walls of the access panel 13, side panels 14, and back panel 15 are all provided with reinforcing ribs 16, which form a continuous, integrated structure. Preferably, both the flanges 141 and side flanges 142 are provided with connection holes for bolt connection.

[0043] The inspection plate 13 is provided with a pressing hole 131 for the lateral movable rod 75 to pass through, one end of the lateral movable rod 75 passes through the pressing hole 131, and the other end is provided with a stop facing the fixed locking seat 73; under the movable guidance of the lateral movable guide column 751 and the lateral locking guide hole 731, external force presses the lateral movable rod 75 and compresses the buckling spring 76 to disengage the buckling head 74 from the buckle hole.

[0044] Therefore, the arrangement of the position-limiting buckle head 7511 can prevent the lateral movable rod 75 from being separated from the fixed locking seat 73 under the action of the buckling spring 76 when the access panel 13 is removed, thereby facilitating maintenance by maintenance personnel.

[0045] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
