[0039] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0040] like Figures 1-7As shown, the vacuum mixer for dental prosthesis processing of this utility model is characterized by comprising a mixer body 1, a mixing cup 2, a mixing blade 31, a suction cylinder 4, a motor 51, and a vacuum pump 52.

An air extraction hole 41 is provided inside the suction cylinder 4, and the mixing cup 2 is connected to the air extraction hole 41. The motor 51 and the vacuum pump 52 are both disposed inside the control box 12, and the output shaft of the motor 51 is connected to the mixing blade 31. The vacuum pump 52 is connected to the air extraction hole 41 for extracting air from the mixing cup 2.

[0041] In practice, the vacuum pump 52 is positioned below the motor 51.

[0042] In specific implementation, gypsum is stored inside the mixing cup 2, and the mixing cup 2 is connected to the suction cylinder 4. At this time, the output shaft of the motor 51 is connected to the stirring blade 31, and the vacuum pump 52 is connected to the mixing cup 2 through the air extraction port 41. Before stirring, the inside of the mixing cup 2 is evacuated to a vacuum state by the vacuum pump 52, and then the stirring blade 31 is driven to rotate by the motor 51. At this time, the stirring blade 31 completes the stirring process of the gypsum inside the mixing cup 2. The mixer of this application, by setting the vacuum pump 52 to evacuate the inside of the mixing cup 2 to a vacuum state before stirring, can effectively prevent the generation of air bubbles in the stirred material when the stirring blade 31 is driven to rotate by the motor 51 to stir the gypsum, thereby improving the quality of the stirred gypsum and making it convenient to use.

[0043] like Figures 5-7 As shown, in a preferred embodiment, the stirring cup 2 includes a cup body 21 and a cup lid 22, wherein the cup body 21 and the cup lid 22 are detachably connected, and the cup lid 22 is provided with a vent hole 221 that communicates with the cup body 21 and the vent hole 41.

[0044] In practice, the cup body 21 is used to store plaster, and the vacuum pump 52 is connected to the cup body 21 through the air extraction hole 41 and the air vent 221.

[0045] It also includes a sealing ring 23, wherein the cup lid 22 has an assembly groove 222 and the cup body 21 is inserted into the assembly groove 222, and the sealing ring 23 is disposed inside the assembly groove 222 and is sealed and fitted to the cup body 21.

[0046] In practice, the sealing ring 23 is an O-ring rubber ring. By setting the sealing ring 23, the connection and sealing between the cup lid 22 and the cup body 21 can be increased.

[0047] It also includes a rotating shaft 32 and a coupling 33. The suction cylinder 4 has a connecting hole 42. The rotating shaft 32 is rotatably mounted on the cup cover 22 and connected to the stirring blade 31. The rotating shaft 32 and the output shaft of the motor 51 both extend into the interior of the connecting hole 42, and the rotating shaft 32 is connected to the output shaft of the motor 51 through the coupling 33.

[0048] The end of the suction cup 4 is provided with a connecting groove 43, and the cup lid 22 is inserted into the inside of the connecting groove 43 and is sealed and fitted with the connecting groove 43.

The transformer 73 is mounted on the base 11 and connected to the mounting platform 72.

[0053] By setting an installation platform 72 on the base 11 to support the mixing drum 2, after the mixing cup 2 is stirred by the motor 51, the motor 51 can be placed on the installation platform 72 and the vibration column 71 and transformer 73 can be started. At this time, the vibration column 71 drives the installation platform 72 to vibrate, thereby causing the mixing cup 2 dragged on the installation platform 72 to vibrate. By vibrating the mixing cup 2, any tiny air bubbles that may exist in the mixing cup 2 can be further eliminated, ensuring the uniformity and density of the material and making it convenient to use.

[0054] Both the vibrating column 71 and the transformer 73 are located inside the base 11, and the base 11 is provided with mounting holes 111 through which the vibrating column 71 and the transformer 73 pass.

[0055] In practice, there are four vibration columns 71, which are distributed circumferentially around the transformer 73. The transformer 73 is connected to the middle of the mounting platform 72.

[0056] In a specific implementation, the assembly hole 111 includes four round holes and a square hole connected to the four round holes. The round holes are used for the vibrating column 71 to pass through, and the square holes are used for the transformer 73 to pass through.

[0057] The mounting platform 72 is provided with a side baffle 74 on its periphery, which is used to cover the mixing cup 2.

[0058] With this design, after the mixing cup 2 is dragged onto the installation platform 72, the side baffle 74 can effectively prevent the mixing cup 2 from accidentally falling off the installation platform 72 during the shaking process.

[0059] like Figure 1 As shown, in a preferred embodiment, a control panel 8 is provided on one side of the control box 12, and an indicator 81 and a control knob 82 are provided on the control panel 8.

Then, the cup lid 22 is inserted into the connecting groove 43. At this time, the output shaft of the motor 51 is connected to the rotating shaft 32 through the coupling 33. The vacuum pump 52 is connected to the inner cavity of the cup body 21 through the suction hole 41 and the vent hole 221. The vacuum pump 52 is started to evacuate the inside of the cup body 21 to a vacuum, and then the motor 51 is started to complete the stirring process of the plaster inside the cup body 21. After stirring is completed, the stirring cup 2 is removed from the suction cylinder 4 and placed on the mounting platform 72. The vibrating column 71 is started to vibrate the mounting platform 72, thereby completing the vibration process of the stirring cup 2. This can further eliminate any tiny air bubbles that may exist in the stirring cup 2, ensuring the uniformity and density of the material.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
