Under above-mentioned structure, when locking, locking member 3 promotes a plurality of release 4 and moves inwards, stops moving after the front end of a plurality of release 4 butt each other, accomplishes the locking, has avoided locking member 3 and release 4 multidimension to remove and has leaded to breaking away from second through-hole 30, has improved this locking mechanism's stability and reliability. And a plurality of release 4 butt each other for when unlocking piece 5 removed along first direction, unlocking piece 5's front end center just right a plurality of release 4's center, be convenient for promote a plurality of release 4 simultaneously and remove, improve unlocking convenience and use impression. Exemplarily, the first through holes 20 and the second through holes 30 are respectively provided with four, four first through holes 20 are uniformly arranged along the circumferential interval of the first mounting seat 31, four second through holes 30 are uniformly arranged along the circumferential interval of the second mounting seat 31, and the four locking members 3 are used for fixing the first connecting seat 1 and the second connecting seat 2 at the periphery, thereby improving the stability and reliability of the locking mechanism. Of course, in other embodiments, the number and distribution positions of the first through holes 20 and the second through holes 30 may be set according to practical situations.

Further, as shown in fig. 2, the locking member 3 includes a mounting seat 31, a locking head 32 and an elastic member 33, the mounting seat 31 is disposed on the first connecting seat 1 and located at one end of the first through hole 20, the locking head 32 is slidably disposed in the first through hole 20 along the second direction, a portion of the locking head 32 can extend into the second through hole 30, two ends of the elastic member 33 are respectively connected to the mounting seat 31 and the locking head 32, and in an initial state of the elastic member 33, a portion of the locking head 32 is located in the first through hole 20, and another portion is located in the second through hole 30. Under the structure, locking and unlocking can be realized without manual pushing or electric pushing. At the locking in-process, when second connecting seat 2 and first connecting seat 1 are close to each other, the lower extreme of second connecting piece extrudees lock head 32, make lock head 32 compression elastic component 33 remove in first through-hole 20, second connecting seat 2 continues to be close to first connecting seat 1 to first through-hole 20 and second through-hole 30 intercommunication, lock head 32 is under the elastic force effect of elastic component 33 automatic stretch into in the second through-hole 30, accomplish the locking process, need not artificial alignment, convenient operation, moreover, the steam generator is simple in structure, the locking time has effectively been saved. Preferably, the elastic member 33 is a compression spring. Of course, in other embodiments, the elastic member 33 may have other structures, such as elastic rubber. Preferably, the lower extreme of second connecting seat 2 is the tapered type, the lower extreme contact tapered end 32's of second connecting seat 2 front end of being convenient for to promote tapered end 32 and remove along the second direction, make second connecting seat 2 remove smoothly, improve the smoothness nature and the operating stability who adds the lock promptly.
