Description
Technical Field
[0001] This utility model belongs to the field of vacuum mixing technology for porcelain powder in porcelain veneers, and specifically relates to a vacuum mixing device for porcelain powder in porcelain veneers with anti-bubble function. Background Technology
[0002] Porcelain crowns are a type of dental restoration made by fusing a metal inner core and an outer layer of porcelain powder at high temperatures. The porcelain powder is the key material for making the outer layer of porcelain crowns, mainly containing ceramic powders such as alumina and zirconium oxide, with rare earth elements added to adjust the color. When making porcelain crowns, the porcelain powder must first be stirred using a mixing device.
[0003] The aforementioned devices lack a vacuum mixing and defoaming structure, meaning that most existing porcelain powder mixers for porcelain crowns simply connect a rotating base to a mixing bowl. Porcelain powder and equal parts of liquid are placed in the mixing bowl, and a stirring spoon is used to stir the mixture. While this method is effective, bubbles are easily generated during the mixing process and are difficult to eliminate. Based on the shortcomings of existing technology, this invention designs a vacuum mixing device for porcelain powder for porcelain crowns with an anti-bubble function. Utility Model Content

[0030] The connecting rod 203 is movably inserted into the inside of the connecting cylinder 306, and the scraper 204 is located inside the mixing bowl 2.
[0031] Further explanation is needed: A connecting ring 103 is provided on the top of the mixer 1. The connecting ring 103 is connected to the rotary motor inside the mixer 1 and is controlled by the switch button 101. The speed knob 102 controls its rotation speed. The retaining ring 201 at the bottom of the mixing bowl 2 is engaged inside the connecting ring 103, so that the rotation of the connecting ring 103 drives the rotation of the mixing bowl 2. A vacuum mechanism 3 is provided on the top of the mixer 1. The vacuum mechanism 3 is used to stir and vacuum the porcelain powder for porcelain veneers inside the mixing bowl 2.
[0032] Example 2
[0033] Please see Figure 2-5 The present invention provides the following technical solution:
[0034] The vacuum mechanism 3 includes a glass cover 301, a one-way valve 302, a suction pipe 303, an exhaust valve 304, a handle 305, a connecting cylinder 306, a limiting strip 307, and a sealing strip 308. The glass cover 301 is located on the top of the mixer 1. The one-way valve 302 is located on the top of the glass cover 301. The suction pipe 303 is located on the top of the one-way valve 302. The exhaust valve 304 is located on the top of the glass cover 301. The handle 305 is fixedly connected to the top of the glass cover 301. The connecting cylinder 306 is fixedly connected inside the glass cover 301. The limiting strip 307 is fixedly connected to the top of the mixer 1. The sealing strip 308 is located inside the limiting strip 307.

[0036] A one-way valve 302 is located on the top of the mixing bowl 2, and a vacuum pump is connected to one side of the suction pipe 303.
[0037] Further explanation is needed: When the glass cover 301 is placed on top of the mixing bowl 2, the connecting rod 203 is inserted into the inside of the connecting cylinder 306, and the scraper 204 is located inside the mixing bowl 2. When the mixing bowl 2 rotates, the scraper 204 stirs the porcelain powder for porcelain crowns. The vacuum pump is connected to the air extraction pipe 303 and the one-way valve 302 to evacuate the part covered by the glass cover 301, so as to eliminate air bubbles when stirring the porcelain powder for porcelain crowns. After stirring and eliminating air bubbles, the air is slowly released through the exhaust valve 304 and then the glass cover 301 is opened.
[0038] Working principle: When a vacuum mixing device for porcelain powder with anti-bubble function is used, a connecting ring 103 is first set on the top of the mixer 1. The connecting ring 103 is connected to the rotary motor inside the mixer 1 and the switch is controlled by the switch button 101. The speed knob 102 controls its rotation speed. The retaining ring 201 at the bottom of the mixing bowl 2 is engaged inside the connecting ring 103, so that when the connecting ring 103 rotates, it drives the mixing bowl 2 to rotate. A vacuuming mechanism 3 is set on the top of the mixer 1. The vacuuming mechanism 3 is used to stir and vacuum the porcelain powder inside the mixing bowl 2.
[0039] When it is necessary to stir and vacuum the porcelain powder for porcelain crowns, first place the glass cover 301 over the top of the mixing bowl 2. At this time, the connecting rod 203 is inserted into the inside of the connecting cylinder 306, and the scraper 204 is located inside the mixing bowl 2. When the mixing bowl 2 rotates, the scraper 204 stirs the porcelain powder for porcelain crowns. The vacuum pump is connected to the air extraction pipe 303 and the one-way valve 302 to vacuum the part covered by the glass cover 301, which facilitates the elimination of air bubbles when stirring the porcelain powder for porcelain crowns. After stirring and eliminating air bubbles, the air is slowly released through the exhaust valve 304 and then the glass cover 301 is opened. This device facilitates the stirring and vacuuming of porcelain powder for porcelain crowns.
