Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Figure 1-5 As shown, a semi-automatic door opening mechanism for an oven comprises an oven 1 and a door 2, wherein the door 2 is hinged on one side of the oven 1, and a magnetic lock 3 for fixing the door 2 is provided on one side of the door 2, and a cylinder pushing device 4 for automatically opening the door of the oven 1 is fixedly connected to the top of the oven 1, and a movable plate 5 for driving a piston rod 7 to move is fixedly connected to the top of the door 2, and a support shaft 6 for enabling the connection between the piston rod 7 and the movable plate 5 to rotate is fixedly connected to one side of the movable plate 5, and a piston rod 7 for driving a piston plate 8 to move is hingedly connected to the outer wall of the support shaft 6, and one end of the piston rod 7 is fixedly connected to a piston plate 8 for squeezing refrigerant in a liquid cooling box 9, and the outer wall of the piston plate 8 is slidably connected to a liquid cooling box 9 for storing refrigerant, as shown in FIG. Figure 1 As shown, the outer wall of the liquid cooling box 9 is connected to a liquid cooling pipe 10 for cooling a circulation pipe 11, the outer wall of the liquid cooling pipe 10 is sleeved with a circulation pipe 11 for circulating hot air, the circulation pipe 11 is connected to the outer wall of the oven 1, the bottom of the circulation pipe 11 is connected to a drain pipe 12 for discharging water droplets in the circulation pipe 11 into a water storage tank 13, the bottom of the drain pipe 12 is connected to a water storage tank 13 for storing water, and the outer wall of the drain pipe 12 is provided with a one-way valve 14 for preventing moisture and water from flowing into the circulation pipe 11.

[0023] It should be noted that, when the staff closes the door 2 of the oven 1, the door 2 will drive the movable plate 5 to move, the movable plate 5 will drive the piston rod 7 to move, the piston rod 7 will drive the piston plate 8 to move, the piston plate 8 will squeeze the refrigerant in the liquid cooling box 9, and the refrigerant will be discharged into the liquid cooling pipe 10. When the oven 1 starts to dry, the hot air in the oven 1 will move upward with the moisture, and the moisture will be discharged into the circulation pipe 11. The liquid cooling pipe 10 will cooperate with the refrigerant to condense the moisture in the circulation pipe 11, so that the moisture condenses into water droplets and falls down. The water droplets will be discharged into the water storage tank 13 through the drain pipe 12, and the one-way valve 14 can prevent the water droplets and moisture in the water storage tank 13 from entering the circulation pipe 11, so that the moisture can be dried quickly.

[0025] It should be noted that when moisture enters the circulation pipe 11, the moisture will impact the rotating blades 18 to cause the rotating blades 18 to rotate, and the rotating blades 18 will drive the transmission rod 16 to rotate, and the transmission rod 16 will drive the rotating scraper 17 to rotate, and the rotating scraper 17 will scrape off the condensed water droplets on the inner wall of the circulation pipe 11, and quickly discharge the condensed water droplets into the drain pipe 12, thereby improving the moisture drying efficiency.
