[0012] Technical effects and advantages of the utility model:

[0013] 1. The utility model is provided with a rotating rod and a sliding part. First, the oven is started to make the rotating motor work. The rotating motor drives the synchronous belt to rotate through the output shaft. The synchronous belt finally rotates the spiral groove rod through the rotating rod to drive the sliding part to move. The movement of the sliding part drives the oven door to close and pushes the push plate. The push plate drives the slide plate to squeeze the pressure spring through the connecting part to contract. When the oven stops working, the pressure spring resets, and finally makes the sliding part move in the opposite direction and pushes the oven door to open, so as to achieve the effect of automatically opening and closing the oven door.

[0014] 2. The utility model is provided with an air box and a one-way valve. When the semiconductor is baked and the rotating motor stops working, the pressure spring pushes the slide plate to move along the inner wall of the air box. The slide plate moves to absorb the hot air inside the oven into the air box through the one-way valve, so that there is no hot air inside the oven, preventing the staff from being scalded by the hot air inside the oven when opening the oven door to take out the baked semiconductor.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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: Refer to the attached specification Figure 1-5 The utility model is a door opening and closing device for an oven, comprising an oven 1, see Figure 2 A rotating motor 2 is fixedly installed inside the oven 1, and a hot fan 3 is fixedly connected to the output shaft of the rotating motor 2. A synchronous belt 4 is sleeved on the outer wall of the output shaft of the rotating motor 2. A rotating rod 5 is inserted inside the synchronous belt 4. The rotating rod 5 is rotatably connected to the inside of the oven 1. For details, see Figure 3 One end of the rotating rod 5 is connected to the driving gear 6 for unidirectional rotation. The unidirectional rotation of the rotating rod 5 and the driving gear 6 makes it possible for the sliding member 9 to drive the spiral groove rod 8 to rotate when it is reset, and the spiral groove rod will not drive the driving gear 6 to rotate through the driven gear 7 to cause it to get stuck. The outer wall of the driving gear 6 is meshed with the driven gear 7. Figure 5 The outer wall of the driven gear 7 is fixedly connected with a spiral groove rod 8, and the outer wall of the spiral groove rod 8 is slidably connected with a sliding member 9, which is slidably connected to the inside of the oven 1 through the sliding member 9, so that when the spiral groove rod 8 drives the sliding member 9, the sliding member 9 will not rotate with the spiral groove rod 8, resulting in the inability to drive the oven door 10 to close the oven 1. The spiral groove rod 8 is rotatably connected to the inside of the oven 1, and the outer wall of the oven 1 is slidably connected with the oven door 10. The sliding member 9 is inserted at the bottom of the oven door 10, and the sliding member 9 is slidably connected to the inside of the oven 1. A push plate 11 is provided on one side of the sliding member 9, and a connecting member 12 is fixedly connected to one side of the push plate 11. For details, see Figure 4 One end of the connecting member 12 away from the push plate 11 is fixedly connected to a slide plate 13 , and one end of the slide plate 13 is fixedly installed with a pressure spring 14 .

[0023] It should be noted that, firstly, the semiconductor is placed inside the oven 1, and then the oven 1 is started to make the rotating motor 2 work, the rotating motor 2 drives the hot fan 3 to work through the output shaft, and at the same time, the rotating motor 2 drives the synchronous belt 4 to rotate through the output shaft, the synchronous belt 4 drives the driving gear 6 to rotate through the rotating rod 5, the driving gear 6 drives the spiral groove rod 8 to rotate through the driven gear 7, the spiral groove rod 8 rotates and drives the sliding member 9 to move, the sliding member 9 moves and drives the box door 10 and the push plate 11 to move, the box door 10 moves to close the oven 1, so as to achieve the effect of automatically sealing the oven 1, the push plate 11 drives the slide plate 13 to slide through the connecting member 12, and the slide plate 13 slides to squeeze the pressure The spring 14 contracts. When the semiconductor baking is completed and the rotating motor 2 stops working, the pressure spring 14 pushes the slide plate 13 to reset. The slide plate 13 drives the push plate 11 to reset through the connecting piece 12. The push plate 11 pushes the sliding member 9 to move in the opposite direction. The sliding member 9 moves in the opposite direction and pushes the box door 10 to open the seal of the baking oven 1, so that the staff can take out the baked semiconductor conveniently. It should be noted that when the sliding member 9 moves to the end of the spiral groove rod 8, the spiral groove rod 8 continues to drive the sliding member 9 to move and squeezes the limit member 16, so that the limit member 16 no longer limits the sliding member 9, allowing the spiral groove rod 8 to drive the sliding member 9 to rotate, which will not cause the spiral groove rod 8 and the sliding member 9 to get stuck.

[0024] Example 2: See Figure 3 A compression spring 15 is fixedly installed on the inner wall of the oven 1. A limiting member 16 is fixedly installed on the end of the compression spring 15 away from the oven 1. By setting the limiting member 16, after the sliding member 9 moves to the end of the spiral groove rod 8, the limiting member 16 can be squeezed to stop limiting the sliding member 9, so as to prevent the spiral groove rod 8 and the sliding member 9 from getting stuck. The limiting member 16 is slidably connected to the inside of the oven 1. For details, see Figure 1 The bottom of the oven 1 is fixedly provided with an air box 17, see Figure 5 The inner wall of the air box 17 is fixedly installed with a limit ring 18, the limit ring 18 is sleeved on the outer wall of the connecting piece 12, the outer wall of the connecting piece 12 is sleeved with a partition 19, the partition 19 is fixedly installed inside the air box 17, and the pressure spring 14 is slidably connected to the inside of the air box 17, see Figure 4 The outer wall of the air box 17 is fixedly connected with a one-way air outlet pipe 20, see Figure 2 A layered plate 21 is fixedly installed inside the oven 1, and a one-way valve 22 is fixedly installed at the bottom of the oven 1. Figure 5 A wind chime 23 is provided at the bottom of the one-way valve 22 , and the wind chime 23 is fixedly installed inside the air box 17 .

[0025] It should be noted that, when the semiconductor baking is completed and the rotating motor 2 stops working, the pressure spring 14 pushes the slide plate 13 to move along the inner wall of the air box 17, and the slide plate 13 moves through the one-way valve 22 to suck the hot air inside the oven 1 into the air box 17, so that there is no hot air inside the oven 1, to prevent the staff from being scalded by the hot air inside the oven 1 when opening the door 10 to take out the baked semiconductor. It should be noted that when the hot air inside the oven 1 enters the air box 17 through the one-way valve 22, the hot air will blow the wind chime 23 to make a sound, reminding the staff that the semiconductor baking is completed. At the same time, after the oven 1 starts working, when the sliding member 9 drives the push plate 11 to slide, the push plate 11 drives the slide plate 13 to slide through the connecting member 12, and the slide plate 13 slides to squeeze the pressure spring 14 to contract and discharge the hot air inside the air box 17 through the one-way exhaust pipe 20, waiting to absorb the hot air inside the oven 1 again.
