[0002] Vacuum microwave drying equipment is used to dry and sterilize materials. Regarding existing technologies for vacuum microwave drying equipment, a search reveals a utility model patent with Chinese patent publication number CN206146132U, which discloses a microwave vacuum drying device. This device mainly includes a vacuum tank and a microwave transmitter, with the transmitter located at the top of the vacuum tank and a door at one end. The door of the vacuum microwave drying device is generally hinged to the microwave drying chamber and then secured with locking devices (e.g., patent publication number CN207963319U). Opening the door usually requires manual operation. However, this manual opening method is inconvenient, and the negative pressure within the vacuum microwave drying chamber further complicates the process, making opening the door time-consuming and laborious. Utility Model Content

[0003] In view of the shortcomings and defects in the existing technology, the purpose of this utility model is to provide a vacuum microwave drying device that solves the problem that the manual opening of the chamber door in the existing vacuum negative pressure device is inconvenient to operate, and the negative pressure inside the vacuum microwave drying chamber makes opening the chamber door time-consuming and laborious.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a vacuum microwave drying device, including a vacuum microwave drying chamber, a vacuum negative pressure mechanism inside the chamber, the left and right ends of the chamber being mounted on the ground via supports, a chamber opening at one end of the chamber, and a chamber door at the opening, a snap-fit ​​flange rotatably connected to the chamber opening of the vacuum microwave drying chamber, the chamber door being hinged to the chamber body via a rotating component that can be flipped, the rotating component being connected to a first telescopic component that drives its rotation. The first telescopic rod is hinged to the vacuum microwave drying chamber. The mounting flange is hinged to the second telescopic rod that drives its rotation, and the body of the second telescopic rod is hinged to the vacuum microwave drying chamber. The mounting flange has an annular mounting groove on the side near the chamber door. Multiple mounting limiting plates are provided on the front side of the annular mounting groove. Multiple arc-shaped locking plates are provided on the chamber door. The arc-shaped locking plates are locked in the annular mounting groove between two adjacent mounting limiting plates. When the mounting flange is rotated, the arc-shaped locking plates are locked behind the mounting limiting plates.

[0005] As a further improvement of this utility model, the annular mounting groove is provided with a first soft silicone strip for sealing.

[0006] As a further improvement of this utility model, the mounting flange is provided with an annular groove, and a second soft silicone strip is mounted in the annular groove. The outer side of the second soft silicone strip is covered with copper mesh.

[0007] As a further improvement of this utility model, a first support plate is fixed on the mounting flange, the telescopic rod end of the second telescopic rod is hinged to the first support plate, a second support plate is fixed on the vacuum microwave drying chamber, and the body of the second telescopic rod is hinged to the second support plate.

[0008] As a further improvement of this utility model, the rotating component includes a third support plate fixed to the front side of the chamber door, two fourth support plates fixed on the vacuum microwave drying chamber body, a fixed shaft fixedly connected between the two fourth support plates, a rotating sleeve rotatably connected to the fixed shaft, the rotating sleeve rotatably connected to the third support plate, and the third support plate hinged to the telescopic rod of the first telescopic rod.

[0009] Compared with the prior art, this utility model has the following advantages:

[0010] 1. A clamping flange is rotatably connected to the vacuum microwave drying chamber. The clamping flange is hinged to a second telescopic rod that drives its rotation. The chamber door is hinged to the vacuum microwave drying chamber via a rotating component, which is also hinged to the first telescopic rod. An annular clamping groove is provided on the clamping flange near the chamber door. Multiple clamping limiting plates are provided in front of the annular clamping groove. An arc-shaped clamping plate is provided on the chamber door. The arc-shaped clamping plate is engaged in the annular clamping groove between two adjacent clamping limiting plates. Rotating the clamping flange causes the arc-shaped clamping plate to engage behind the clamping limiting plate; thus, when the door is closed… When the second telescopic rod extends, it rotates the clamping flange into place. The first telescopic rod extends, causing the door to close onto the clamping flange. At this time, the arc-shaped clamping plate on the door is engaged in the annular clamping groove between the two clamping limit plates. Then, the second telescopic rod retracts, causing the clamping flange to rotate. Afterward, the clamping limit plate on the clamping flange blocks the front side of the arc-shaped clamping plate, thus blocking and limiting the door, completing the closing process. This prevents the door from opening and secures the door. When the door is opened, the second telescopic rod retracts, causing the mounting flange to rotate until the mounting limit plate on the mounting flange avoids the arc-shaped locking plate, thereby unlocking the limiting position on the arc-shaped locking plate. At this time, the first telescopic rod retracts, causing the door to open. Driven by the first and second telescopic rods, the negative pressure inside the vacuum microwave drying chamber can be easily overcome, making the opening and closing of the door very convenient, saving time and effort. In addition, the locking and fixing method using rotating teeth ensures a tighter fit between the vacuum drying chamber and the door. After locking, a self-locking mechanism is formed, making it more secure. Even if the driving efficiency of the first and second telescopic rods loosens and decreases, the door will not loosen and open, maintaining a sealing effect.

[0011] 2. A first soft silicone strip for sealing is provided in the annular mounting groove, thereby achieving a certain sealing effect.

[0012] 3. By using a copper mesh, the microwaves inside the vacuum microwave drying chamber can be shielded, and the copper mesh covering the outside of the second soft silicone strip can be used to tightly support the copper mesh in the annular groove. Attached Figure Description

[0019] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0020] This utility model discloses a vacuum microwave drying device. (Refer to...) Figure 1 and Figure 2 A vacuum microwave drying device includes a vacuum microwave drying chamber 1. The vacuum setting structure, microwave setting structure, and implementation principle of the vacuum microwave drying chamber 1 are the same as those of the prior art. For details, please refer to the patent technology with patent number CN207963319U or patent number CN206146132U. This application has not made any improvements, so it will not be described in detail.

[0021] This application differs in that the vacuum microwave drying chamber is equipped with a vacuum negative pressure mechanism. The left and right ends of the vacuum microwave drying chamber 1 are mounted on the ground via supports 2. One end of the vacuum microwave drying chamber 1 has a chamber opening 3, and a chamber door 4 is located at the chamber opening 3. A snap-fit ​​flange 5 is rotatably connected to the vacuum microwave drying chamber 1 at the chamber opening 3. The chamber door 4 is hinged to the vacuum microwave drying chamber 1 via a rotating component 6, which is hinged to a first telescopic rod 7 that drives its rotation. The body of the first telescopic rod 7 is hinged to the vacuum microwave drying chamber 1. Specifically, the rotating component 6 includes a third support plate 61 fixed to the front side of the chamber door 4. Two fourth support plates 62 are fixed to the vacuum microwave drying chamber 1, and a fixed shaft 63 is fixedly connected between the two fourth support plates 62. A rotating sleeve 64 is rotatably connected to the fixed shaft 63, and the rotating sleeve 64 is rotatably connected to the third support plate 61. The third support plate 61 is hinged to the telescopic rod of the first telescopic rod 7.

[0022] The mounting flange 5 is hinged to the second telescopic rod 8 that drives its rotation, and the body of the second telescopic rod 8 is hinged to the vacuum microwave drying chamber 1. Specifically, a first support plate 13 is fixed on the mounting flange 5, the telescopic rod end of the second telescopic rod 8 is hinged to the first support plate 13, a second support plate 14 is fixed on the vacuum microwave drying chamber 1, and the body of the second telescopic rod 8 is hinged to the second support plate 14.

[0023] like Figure 2 As shown, the clamping flange 5 has an annular clamping groove 9 on one side near the door 4. Multiple clamping limiting plates 10 are fixed around the front side of the annular clamping groove 9. Multiple arc-shaped clamping plates 11 are provided on the door 4. The arc-shaped clamping plates 11 are clamped in the annular clamping groove 9 between two adjacent clamping limiting plates 10. When the clamping flange 5 is rotated, the arc-shaped clamping plates 11 are clamped on the rear side of the clamping limiting plates 10.

[0024] like Figure 3 As shown, the annular mounting groove 9 is provided with a first soft silicone strip 12 for sealing, thereby achieving a certain sealing effect. Additionally, the mounting flange 5 is provided with an annular groove 16, within which a second soft silicone strip 17 is mounted. The outer side of the second soft silicone strip 17 is covered with a copper mesh 15, which can also be replaced with a stainless steel mesh. This copper mesh can shield the microwaves inside the vacuum microwave drying chamber. The copper mesh 15 covering the outer side of the second soft silicone strip 17 can tightly support the copper mesh within the annular groove 16, while also providing a certain degree of sealing to ensure positive or negative pressure.

[0025] This utility model features a snap-fit ​​flange 5 rotatably connected to a vacuum microwave drying chamber 1. The snap-fit ​​flange 5 is hinged to a second telescopic rod 8 that drives its rotation. The chamber door 4 is hinged to the vacuum microwave drying chamber 1 via a rotating component 6, which is hinged to a first telescopic rod 7. An annular snap-fit ​​groove 9 is provided on the snap-fit ​​flange 5 on the side near the chamber door 4. Multiple snap-fit ​​limiting plates 10 are provided on the front side of the annular snap-fit ​​groove 9. An arc-shaped snap-fit ​​plate 11 is provided on the chamber door 4. The arc-shaped snap-fit ​​plate 11 is snapped into the annular snap-fit ​​groove 9 between two adjacent snap-fit ​​limiting plates 10. When the snap-fit ​​flange is rotated, the arc-shaped snap-fit ​​plate 11 is snapped into the rear side of the snap-fit ​​limiting plate 10. When the door is closed, the telescopic rod of the second telescopic rod 8 extends, causing the clamping flange 5 to rotate into place. The telescopic rod of the first telescopic rod 7 extends, thereby causing the door 4 to close onto the clamping flange 5. At this time, the arc-shaped clamping plate 11 on the door 4 is engaged in the annular clamping groove 9 between the two clamping limit plates 10. Then, the telescopic rod of the second telescopic rod 8 retracts, and the second telescopic rod 8 causes the clamping flange 5 to rotate. Afterward, the clamping limit plate 10 on the clamping flange 5 blocks the front side of the arc-shaped clamping plate 11, thereby blocking and limiting the door 4, thus completing the closing. This can prevent the door 4 from opening and limit and secure the door 4. When the door is opened, the telescopic rod of the second telescopic rod 8 retracts, causing the clamping flange 5 to rotate until the clamping limit plate 10 on the clamping flange 5 avoids the arc-shaped clamping plate 11, thereby unlocking the limit on the arc-shaped clamping plate 11. At this time, the telescopic rod of the first telescopic rod 7 retracts, and the first telescopic rod 7 drives the door 4 to open. Driven by the first telescopic rod 7 and the second telescopic rod 8, the negative pressure inside the vacuum microwave drying chamber 1 can be easily overcome. The opening and closing of the door 4 is very convenient, saving time and effort.
