DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0024] Example 1: Figures 1 to 5 The illustrated easy-to-replace module mixer includes a fixed frame 1 and a carrier device 2, which are two relatively independent structures. The fixed frame 1 is a square frame structure, with a raised fixed surface 7 on the upper side of the fixed frame 1, and a ring structure on the lower side of the fixed frame 1. Two horizontally distributed mounting holes are provided on the lower side of the fixed frame 1, and a lock button 3 is connected to the mounting hole through a rotating shaft. The rotating shaft end of the lock button 3 is located inside the fixed frame 1, and the other end of the lock button 3 is located outside the fixed frame 1, so that the operator can operate the lock button 3. Among them, the position on the ring structure of the fixed frame 1 and corresponding to the lock button 3 is a hollow structure, so that the lock button 3 can rotate around the rotating shaft without being blocked.

[0025] A lock opening 3.1 structure is arranged at one end of the lock button 3 close to the rotating shaft. The lock opening 3.1 is a plate-shaped structure with an opening. The lock opening 3.1 structure can be integrally formed and fixed with the lock button 3, or can be fixed to the lock button 3 by a fixing part.

[0026] The carrier device 2 is provided at the lower side of the fixing frame 1. The carrier device 2 supports the fixing frame 1. A lock slot 4 is provided at one side of the carrier device 2 near the lock button 3. The position of the lock slot 4 corresponds to the position of the lock button 3 and is located below the lock button 3. The lock slot 4 includes an escape area 4.2 and a card block 4.1 provided on the wall of the lock slot 4. The card block 4.1 can cooperate with the lock opening 3.1 on the lock button 3. Figure 4 As shown, when the lock button 3 is in a horizontal state, the lock opening 3.1 and the card block 4.1 are engaged with each other, and in the vertical direction, the fixed frame 1 and the carrier device 2 are fixed together. When the module needs to be disassembled, the lock button 3 located outside the fixed frame 1 is pressed downward, and the lock button 3 rotates around the shaft, and the lock opening 3.1 located at the end of the shaft will rotate clockwise around the shaft, and the lock opening 3.1 will be separated from the card block 4.1 structure. At this time, the limit of the fixed frame 1 and the carrier device 2 in the vertical direction is released, that is, the mixer can be disassembled.

[0027] In addition, on the side of the fixing frame 1 away from the lock button 3 ( Figure 3 The first card slot 5 is also provided in the ring structure at the lower side of the fixed frame 1. The first card slot 5 is an "L" shaped structure. The ring structure can shield the internal structure of the fixed frame 1, improving the aesthetics of the mixer. At the same time, the outer surface of the ring structure is connected with the outer surface of the carrier device 1 in vertical height. A second card slot 6 is provided on the side of the carrier device 1 away from the lock slot 4. Figure 2 As shown in the left side view in the middle, the second card slot 6 is in an inverted "L" shape. The first card slot 5 and the second card slot 6 can cooperate with each other, and the first card slot 5 and the second card slot 6 can form a matching surface in the vertical direction, so as to form a limited fixation in the vertical direction; at the same time, since the first card slot 5 is in an "L" shape and the second card slot 6 is in an inverted "L" shape, after the first card slot 5 and the second card slot 6 cooperate, a limited fixation can also be formed in the horizontal direction. At this time, combined with the lock 3.1 structure at the lock button 3, the fixing frame 1 and the carrier device 2 can be completely fixed.

[0028] Specifically, Figure 3 The state shown is the initial state, and the mixer is disassembled.

[0029] First, press the lock button 3 located outside the fixed frame 1 downward, and the lock button 3 rotates around the shaft. The lock mouth 3.1 located at the end of the shaft will rotate clockwise around the shaft, and the lock mouth 3.1 will disengage from the block 4.1 structure. At this time, the vertical limit of the right side of the fixed frame 1 and the carrier device 2 is released.

[0030] Then, when the fixing frame 1 is pushed from right to left, the first slot 5 will move to the left and slowly disengage from the second slot 6, and the vertical limit of the left side of the fixing frame 1 and the carrier device 2 will be released. Finally, the fixing frame 1 can be removed as a whole, and then the replaceable module 9 inside can be replaced, and the replaceable module 9 is specifically a metal module block.

[0031] When assembly operation is required, the above operation can be performed in reverse.

At the same time, in order to make the thermal conductive module 10 fit the replaceable module 9 better, an elastic component 11 is provided between the supporting plate 8 and the thermal conductive module 10. Specifically, the elastic component 11 is a spring structure. Three groups of spring structures are provided and are evenly distributed between the supporting plate 8 and the thermal conductive module 10.

[0036] When in normal use, the elastic component 11 is in a compressed state. Under the elastic force of the elastic component 11, the thermal conductive module 10 will fit upward with the replaceable module 9, and at the same time, the replaceable module 9 will be pressed upward against the lower side of the fixing surface 7, thereby enhancing the fixing effect of the replaceable module 9.

The first card slot 5 and the second card slot 6 can cooperate with each other, and the first card slot 5 and the second card slot 6 can form a matching surface in the vertical direction, so as to form a limited fixation in the vertical direction; at the same time, since the first card slot 5 is in an "L" shape and the second card slot 6 is in an inverted "L" shape, after the first card slot 5 and the second card slot 6 cooperate, a limited fixation can also be formed in the horizontal direction. At this time, combined with the lock 3.1 structure at the lock button 3, the fixing frame 1 and the carrier device 2 can be completely fixed.

Finally, the fixing frame 1 can be removed as a whole, and then the replaceable module 9 inside can be replaced, and the replaceable module 9 is specifically a metal module block.
