[0024] See also Figure 1-Figure 3 , an embodiment provided by the utility model: a dental muffle furnace;

[0025] It includes a support block 1, a mounting groove 2 and a muffle furnace body 3, wherein an anti-slip pad 102 is symmetrically installed on the bottom of the support block 1, a controller 101 is installed on the front of the support block 1, a mounting groove 2 is provided on the top of the support block 1, and the mounting groove 2 is located in front of the muffle furnace body 3, a refrigerator 201 is installed inside the mounting groove 2, a discharge net 202 is provided on the top of the mounting groove 2, a heat dissipation groove 203 is provided at the bottom of the mounting groove 2, and the heat dissipation groove 203 runs through the bottom of the support block 1, a muffle furnace body 3 is installed on the top of the support block 1, a furnace cavity 301 is provided on the front of the muffle furnace body 3, a slide groove 302 is provided at the bottom of the furnace cavity 301, heating cavities 303 are symmetrically provided on both sides of the furnace cavity 301, and a heating rod 304 is installed inside the heating cavity 303;

[0026] The support block 1 provides a position for the opening of the installation groove 2, and also enables the muffle furnace body 3 to be installed. The use of the muffle furnace body 3 is controlled by the controller 101. The installation groove 2 provides space for the installation of the refrigerator 201. By installing the refrigerator 201 inside the installation groove 2, the cold air generated by the refrigerator 201 can be discharged to the outside through the exhaust net 202, thereby cooling the dental items placed on the top of the placement plate 5, accelerating its cooling speed, and allowing the staff to take out the processed dental items faster. The exhaust net 202 is used to protect foreign matter from falling into the inside of the installation groove 2. Dental items that need to be processed by the muffle furnace are placed inside the furnace cavity 301. The heating rod 304 in the heating cavity 303 converts electrical energy into thermal energy after power is turned on, so that the temperature inside the furnace cavity 301 is increased, so that the dental items can be heated.

[0027] See also Figure 1 , Figure 4 and Figure 5 , an embodiment provided by the utility model: a dental muffle furnace;

[0028] It includes a sealing door 4, a placement plate 5 and a mounting tube 6. The sealing door 4 is movably mounted on the front of the muffle furnace body 3, a sealing block 401 is mounted on the inner side of the sealing door 4, a placement plate 5 is mounted on the bottom of the furnace chamber 301 through a slide groove 302, a slider 503 is symmetrically mounted on the bottom of the placement plate 5, and the slider 503 is slidably mounted inside the slide groove 302, a plurality of through holes 501 are opened on the top of the placement plate 5, a pressure rod 502 is mounted on the front of the placement plate 5, a mounting tube 6 is arranged on the back of the furnace chamber 301, a connecting spring 601 is arranged inside the mounting tube 6, a connecting block 602 is mounted on one end of the connecting spring 601, a telescopic rod 603 is arranged on the front of the connecting block 602, and one end of the telescopic rod 603 is connected to the back of the placement plate 5;

[0029] By closing the sealing door 4, the sealing block 401 will enter the furnace chamber 301, thereby sealing the furnace chamber 301 to prevent heat dissipation from affecting the heating effect. The placement plate 5 provides a position for placing the processed items, and the items are stored in the interior of the furnace chamber 301 through the placement plate 5. Since the placement plate 5 is movably installed through the slider 503, the placement plate 5 can slide back and forth in the interior of the furnace chamber 301. When the sealing door 4 is closed, the sealing block 401 will contact one end of the pressure rod 502, and the pressure rod 502 will cause the placement plate 5 to slide into the interior of the furnace chamber 301. At this time, the telescopic rod 603 moves toward the interior of the installation tube 6, and the connecting spring 601 is compressed to generate a reverse elastic force. When the sealing door 4 is opened, the reverse elastic force generated by the connecting spring 601 drives the telescopic rod 603 to move forward, thereby pushing the placement plate 5 out of the interior of the furnace chamber 301, thereby making it convenient for the staff to take out the dental items on the placement plate 5, and it is also convenient for cooling through the through hole 501.

[0030] Working principle: Before using the dental muffle furnace, you should first check whether there are any problems that affect the use of the dental muffle furnace. First, place the muffle furnace at the position where it needs to be used through the anti-slip pad 102, place the dental items that need to be heated on the top of the placement plate 5, close the sealing door 4, and the placement plate 5 will be pushed into the interior of the furnace chamber 301. After the processing is completed, open the sealing door 4, the placement plate 5 will be automatically popped out, and at the same time turn on the refrigerator 201 to accelerate the cooling of the items through the cold air generated by the refrigerator 201.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
