[0025] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] This utility model provides, for example Figure 1-4 The deaerator head shown includes a deaerator cylinder 1 and a deaerator end cap 2. A first fixing ring 3 is fitted on the surface of the deaerator cylinder 1, and a second fixing ring 4 is fitted on the surface of the deaerator end cap 2. Fixing blocks 5 are fixedly connected to both sides of the first fixing ring 3. A fixing post 6 is bolted to the top of the fixing block 5. Fixing boxes 7 are bolted to both sides of the top of the second fixing ring 4. The top of the fixing post 6 extends into the inner cavity of the fixing box 7. Slots are sequentially opened on both sides of the fixing post 6 from top to bottom. A snap-fit ​​assembly 8 that cooperates with the slots is provided in the inner cavity of the fixing box 7.

[0027] To facilitate the replacement of deoxygenation head 2, such as Figure 2As shown, the snap-fit ​​assembly 8 includes a rotating shaft 81, a driving bevel gear 82, a driven bevel gear 83, a threaded rod 84, a threaded block 85, a base plate 86, and a locking block 87. The rotating shaft 81 is rotatably connected to the center of the top of the fixed box 7 via a bearing. The driving bevel gear 82 is keyed to the surface of the rotating shaft 81. The driven bevel gear 83 meshes with the bottom of the driving bevel gear 82. The threaded rod 84 is keyed to the inner cavity of the driven bevel gear 83. Both ends of the threaded rod 84 are rotatably connected to the top of both sides of the inner cavity of the fixed box 7 via bearings. Threaded blocks 85 are threaded to both the positive and negative threads of the threaded rod 84. The base plate 86 is bolted to the bottom of the threaded block 85. Locking blocks 87 are sequentially bolted to the opposite side of the base plate 86 from top to bottom. Some of the opposing locking blocks 87 engage with the inner cavity of the locking groove. During installation… The user picks up the deoxygenating head 2 and places the second fixing ring 4 on the first fixing ring 3. At this time, the fixing post 6 is inserted into the fixing box 7. Then, the user moves the limiting rod 9 upward. At this time, the limiting rod 9 drives the first slider 12 to squeeze the spring. Then, the user turns the handle, which drives the rotating shaft 81 to rotate. At this time, the rotating shaft 81 drives the driving bevel gear 82 to rotate, which in turn drives the driven bevel gear 83 to rotate. Then, the driven bevel gear 83 drives the positive and negative threaded rods 84 to rotate. Then, the positive and negative threaded rods 84 drive the threaded blocks 85 to move towards each other. The threaded blocks 85 drive the base plate 86 to move towards each other. The base plate 86 drives the locking block 87 to move towards each other, so that the locking block 87 is inserted into the locking groove to fix the fixing post 6. Then, the limiting rod 9 is passed through the through hole and locked with the limiting hole to fix the handle, completing the installation of the deoxygenating head 2.

[0028] To facilitate the rotation of the rotating shaft 81, such as Figure 2 As shown, a handle is bolted to the top of the rotating shaft 81, and through holes are provided on both sides of the top of the handle; making it convenient for the user to rotate the rotating shaft 81.

[0029] like Figure 2 and Figure 3 As shown, limiting holes are provided on both sides of the top center of the fixed box 7, and the inner cavity of the limiting hole is engaged with the limiting rod 9. Side plates 10 are bolted to both sides of the top of the fixed box 7. A first sliding groove 11 is provided on the opposite side of the side plate 10. A first slider 12 is slidably connected to the inner cavity of the first sliding groove 11. The top of the limiting rod 9 passes through the through hole and is bolted to the bottom of the first slider 12. A spring is fixedly connected to the top of the inner cavity of the first sliding groove 11, and the bottom of the spring is fixedly connected to the top of the first slider 12. The handle is fixed to prevent the locking block 87 from moving out of the slot when the handle is rotated.

[0030] In order to limit the position of the base plate 86, such as Figure 2As shown, a second sliding groove 13 is provided on both sides of the bottom of the inner cavity of the fixing box 7. A second slider 14 is slidably connected to the inner cavity of the second sliding groove 13. The top of the second slider 14 is bolted to the bottom of the base plate 86. The base plate 86 is limited and moved to assist the base plate 86 in moving, thereby assisting the card block 87 to be accurately inserted into the card slot.

[0031] To protect block 87, such as Figure 4 As shown, a buffer block is attached to the opposite side of the card block 87; it provides buffer protection when the card block 87 is inserted into the card slot.

[0032] Finally, seal the fixing box 7, such as... Figure 2 As shown, a sealing gasket is bonded to the center of the bottom of the inner cavity of the fixing box 7, and the inner side of the sealing gasket is in contact with the surface of the fixing post 6; thus improving the sealing performance of the fixing box 7.

[0033] In summary, when the deaerator head 2 needs to be replaced, the user moves the limiting rod 9 upward until it moves out of the limiting hole and the through hole. Then, the user reverses the handle, which drives the rotating shaft 81 to reverse. At this time, the rotating shaft 81 drives the driving bevel gear 82 to reverse, which in turn drives the driven bevel gear 83 to reverse. Then, the driven bevel gear 83 drives the positive and negative threaded rod 84 to reverse. Then, the positive and negative threaded rod 84 drives the threaded block 85 to move in the opposite direction. The threaded block 85 drives the base plate 86 to move in the opposite direction. The base plate 86 drives the locking block 87 to move in the opposite direction, so that the locking block 87 moves out of the locking slot. Then, the user moves the deaerator head 2 upward, so that the fixing column 6 moves out of the fixing box 7, completing the disassembly of the deaerator head 2.
