Description

Technical Field

[0001] This application relates to the field of cooling device technology, and specifically discloses a rapid cooling device for porcelain crowns. Background Technology

[0002] As people's living standards improve, they are paying more and more attention to the protection and restoration of their teeth. For missing teeth, porcelain crowns are the most common method of restoration. Metal-ceramic crowns are currently the most widely used full-crown restoration in clinical practice, combining the advantages of the good mechanical strength of cast metal crowns with the aesthetics of all-ceramic crowns, making them a relatively ideal restoration.

[0003] The manufacturing process of porcelain crowns mainly involves heating and baking the metal base and porcelain layer in a furnace. After heating, the porcelain crown reaches a high temperature and needs to be cooled. Existing porcelain crown cooling devices require spraying water onto the entire crown for rapid cooling. However, the contact surface between the metal base and the porcelain layer in the porcelain crown vaporizes and expands upon contact with water. The resulting water vapor oxidizes the metal base, leading to cracking of the porcelain layer at the contact surface and a decrease in the peel force between the metal base and the porcelain layer, thus affecting the use of the porcelain crown.

[0004] Therefore, the inventors have provided a rapid cooling device for porcelain crowns to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of existing rapid cooling devices for porcelain crowns, which directly spray water to cool the porcelain crowns. This causes the surface of the contact surface between the metal substrate and the porcelain layer to vaporize and expand upon contact with water. At the same time, the water vapor formed oxidizes the metal substrate, which leads to cracking of the porcelain layer on the contact surface between the metal substrate and the porcelain layer and a decrease in the peel force between the metal substrate and the porcelain layer, thus affecting the use of the porcelain crown.

[0006] To achieve the above objectives, the basic solution of this utility model provides a rapid cooling device for porcelain crowns, including a cooling water tank and guide post assemblies symmetrically arranged on both sides of the cooling water tank. Each guide post assembly includes a support post on one side of the cooling water tank, a sliding block 1 and a sliding block 2 slidably connected from top to bottom on the support post, a locking element 1 on the sliding block 2 for locking the sliding block 1 and the sliding block 2, and a locking element 2 on the support post for locking the sliding block 2 and the support post. It also includes a mounting plate on the top of the support post and a cylinder on the mounting plate for driving the sliding block 1 to slide.

[0007] Both sliding block one and sliding block two have an inverted L-shaped structure. The vertical arms of sliding block one and sliding block two, which are located on the same support column, are slidably connected and can both extend into the cooling water tank. An upper shell is provided between the bottom of the vertical arms of sliding block one, and a lower shell is provided between the bottom of the vertical arms of sliding block two, which engages with the upper shell. The lower shell has a slot for placing porcelain teeth. An air inlet pipe is connected to the upper shell, and an air outlet pipe is connected to the lower shell. The free end of the air outlet pipe extends out of the cooling water tank, and the free end of the air inlet pipe is connected to a fan.

[0008] The principle and effect of this basic scheme are as follows:

[0009] This invention first places the porcelain crown to be cooled into the placement groove of the lower housing. Then, the cylinder is activated, and the cylinder drives the upper housing to descend and engage with the lower housing through the connecting plate. Locking component one locks sliding block one and sliding block two into a whole. Locking component two unlocks sliding block two from the support column. The cylinder drives sliding block one and sliding block two to descend as a whole until the top of the upper housing is located in the cooling water tank, so as to cool the porcelain crown in the groove of the lower housing as a whole.

[0010] Compared with the prior art, this utility model has a lower shell that wraps around the porcelain crown and an upper shell that engages with the lower shell. An air inlet pipe connects to the upper shell and an air outlet pipe connects to the lower shell. While blowing air to cool the porcelain crown inside the lower shell, the porcelain crown inside the lower shell is also placed in a cooling water tank for overall water bath cooling. This solves the problem of existing rapid cooling devices for porcelain crowns, which directly spray water to cool the porcelain crown. This causes the surface of the contact surface between the metal base and the porcelain layer in the porcelain crown to vaporize and expand upon contact with water. At the same time, the water vapor formed oxidizes the metal base, which can lead to cracking of the porcelain layer on the contact surface between the metal base and the porcelain layer and a decrease in the peel force between the metal base and the porcelain layer, thus affecting the use of the porcelain crown.

[0011] Furthermore, the bottom of the horizontal arm of the first sliding block is provided with an armature plate, and the first locking element is an electromagnet located at the top of the second sliding block and magnetically attracted to the armature plate. The side wall of the horizontal arm of the second sliding block is provided with an armature plate, and the second locking element is an electromagnet located on the support column and magnetically attracted to the armature plate. The support column is also provided with a controller electrically connected to the first and second electromagnets and the cylinder. The controller controls the de-energization and energization of the first and second electromagnets, which can conveniently control the attraction of the first and second sliding blocks and the attraction of the second sliding block to the support column, making the engagement of the upper and lower housings more accurate and convenient.

[0012] Furthermore, a sliding chamber is formed on the side wall of the second sliding block, which is slidably connected to the second armature plate. A return spring is fixed between the second armature plate and the bottom surface of the sliding chamber. A groove is formed on the support column to accommodate the second armature plate, and the second electromagnet is fixed to the bottom surface of the groove. The first armature plate slides in the sliding chamber, and the second electromagnet uses electromagnetic attraction to draw the first armature plate into the groove, making the magnetic attraction between the first armature plate and the second electromagnet more stable and ensuring the stability of the first sliding block on the support column.

[0013] Furthermore, vertical grooves are provided on opposite sides of the vertical arms of sliding block two, and sliders that can slide within the grooves are fixed to opposite sides of the vertical arms of sliding block one. The vertical arm of sliding block one slides within the grooves on the vertical arm of sliding block two, limiting and guiding sliding block one, making sliding block one more stable during sliding.

[0014] Furthermore, the upper and lower housings are respectively provided with interlocking slots and blocks on opposite sides, and a sealing gasket is fixed to the bottom surface of the slot. When the block engages with the slot, the sealing gasket seals it, resulting in a better sealing effect between the upper and lower housings.

[0015] Furthermore, multiple placement slots are provided and evenly distributed on the lower housing, with adjacent placement slots interconnected. The presence of multiple interconnected placement slots facilitates the cooling of multiple ceramic coatings simultaneously, improving work efficiency.

[0016] Furthermore, a throttling valve is installed on the air inlet duct. The gas blown out by the fan is cooled by the throttling valve, and then ventilates the upper and lower housings through the air inlet duct, allowing the porcelain crowns in the lower housing to cool down faster.

[0017] Furthermore, the side wall of the cooling water tank is connected to an inlet pipe and an outlet pipe, respectively. The free end of the outlet pipe is connected to a radiator, and the free end of the inlet pipe is connected to a circulation pump. The radiator and the circulation pump are connected by a pipe. The cooperation of the circulation pump and the radiator cools and circulates the water in the cooling water tank, ensuring that the temperature in the cooling water tank remains at a low level, thus rapidly cooling the porcelain crown placed in the slot.

[0025] A rapid cooling device for porcelain crowns, implementing, for example... Figure 1 , 2 As shown in Figures 3 and 4: The system includes a cooling water tank 1 and guide pillar assemblies symmetrically installed on the left and right sides of the cooling water tank 1. Each guide pillar assembly includes a support pillar 2 installed on one side of the cooling water tank 1, a sliding block 3 and a sliding block 4 sliding sequentially from top to bottom on the support pillar 2, a locking element 1 installed on the sliding block 4, and a locking element 2 installed on the support pillar 2. Specifically, each support pillar 2 has a vertical groove on its opposite side. The sliding blocks 3 and 4 are both inverted L-shaped structures, each consisting of a horizontal arm and a vertical arm perpendicular to the horizontal arm. The horizontal arms of both sliding blocks 3 and 4 slide within the vertical grooves.

[0026] An armature plate 6 is welded to the bottom of the horizontal arm of sliding block 3. Locking element 1 is an electromagnet 5 fixedly installed at the top of the horizontal arm of sliding block 4. An armature plate 8 is installed on the side wall of the horizontal arm of sliding block 4. Locking element 2 is an electromagnet 7 installed on the support column 2. Specifically, each side wall of the horizontal arm of sliding block 4 has a sliding chamber with an opening facing the support column 2 on the same side. The armature plate 8 slides within the sliding chamber. A return spring is fixedly installed between the armature plate 8 and the bottom surface of the sliding chamber. Grooves opposite to the sliding chambers are opened on the inner bottom surface and side wall of the vertical groove. Electromagnet 7 is fixedly installed on the bottom surface of the groove. When electromagnet 7 is powered, it attracts the armature plate 8, and one end of the armature plate 8 extends into the groove, thus fixing the sliding block 4 and causing the return spring to stretch. When electromagnet 7 is de-energized, the elastic force of the return spring is released, causing the armature plate 8 to slide out of the groove, thus not affecting the sliding of sliding block 4 on the support column 2.

[0027] A mounting plate is welded between the tops of the support columns 2, and a cylinder 9 is fixedly mounted on the mounting plate. A connecting plate is welded between the tops of the vertical arms of the sliding blocks 3. The output shaft of the cylinder 9 passes through the mounting plate and is fixedly mounted to the connecting plate. A single-chip microcomputer controller is provided on the support column 2, which is electrically connected to the electromagnet 5, the electromagnet 7 and the cylinder 9. The cylinder 9 drives the sliding blocks 4 on both sides to slide simultaneously through the connecting plate, ensuring the synchronous movement of the sliding blocks 4 on different support columns 2.

[0028] Both the vertical arms of sliding block 3 and sliding block 4 can extend into the cooling water tank 1. The vertical arms of sliding block 4 have symmetrical grooves on opposite sides. The vertical arms of sliding block 3 have symmetrically fixed sliders that slide within the grooves on opposite sides. Support rods 1 are welded to the bottom of the outer sides of the vertical arms of sliding block 4. Semi-cylindrical lower housings 11 are fixedly installed between the support rods 1. The lower housings 11 have several evenly distributed placement slots 12 for placing porcelain crowns, and adjacent placement slots 12 are interconnected. Support rods 2 are welded to the bottom of the outer sides of the vertical arms of sliding block 3. Semi-cylindrical upper housings 1 are fixedly installed between the support rods 2. 0. An annular groove 13 is opened on the side of the upper housing 10 facing the lower housing 11. An annular sealing gasket is fixedly installed on the bottom surface of the groove 13. An annular locking block 14 that engages with the groove 13 is fixedly installed on the upper surface of the lower housing 11. A pressure sensing plate that is electrically connected to the microcontroller is provided on the sealing gasket. When the upper housing 10 descends, the locking block 14 on the lower housing 11 extends into the groove 13. The locking block 14 is inserted into the bottom of the groove 13 and contacts the pressure sensing plate on the sealing gasket. The pressure sensing plate generates an electrical signal, which causes the microcontroller to control the electromagnet 5 to electromagnetically attract the armature plate 6, and then control the electromagnet 7 to de-energize, causing the armature plate 8 to slide out of the groove.

[0029] In this embodiment, an air inlet pipe 15 is connected to the right side of the upper housing 10, and a throttle valve is installed on the air inlet pipe 15. A fan is connected to the free end of the air inlet pipe 15. An air outlet pipe 16 is connected to the left side of the lower housing 11. A through hole is opened on the side wall of the cooling water tank 1, and the air outlet pipe 16 extends out of the cooling water tank 1 through the through hole. Both the air inlet pipe 15 and the air outlet pipe 16 are flexible hoses. The throttle valve cools the air blown out by the fan, and then blows it into the placement slot 12 of the lower housing 11 through the air inlet pipe 15 to further cool the porcelain crown, making its cooling speed faster; the front and rear side walls of the cooling water tank 1 The upper part is connected to the water outlet pipe 18 and the water inlet pipe 17 respectively. The radiator and the circulation pump are arranged in sequence on the right side of the cooling water tank 1. The inlet of the radiator is connected to the free end of the water outlet pipe 18, and the outlet of the circulation pump is connected to the free end of the water inlet pipe 17. The outlet of the radiator and the inlet of the circulation pump are connected by a pipe. The circulation pump and the radiator work together to cool and circulate the water in the cooling water tank 1, ensuring that the temperature in the cooling water tank 1 remains at a low temperature, so that the porcelain teeth in the lower shell placement slot are cooled better. The microcontroller is electrically connected to the fan, radiator and circulation pump.

[0030] In use, the porcelain tooth to be cooled is first placed in the placement slot 12 of the lower housing 11. The cylinder 9 is started by the microcontroller controller. The cylinder 9 drives the sliding blocks 3 on both sides to descend through the connecting plate, which in turn drives the upper housing 10 between the sliding blocks 3 to descend. The locking block 14 on the lower housing 11 is inserted into the locking slot 13 on the upper housing 10 to seal the lower housing 11. The pressure sensing plate on the sealing gasket in the locking slot 13 transmits an electrical signal to the microcontroller sensor, causing the microcontroller sensor to control the electromagnet 5 to be energized to attract the armature plate 6, and control the electromagnet 7 in the groove to be de-energized. Under the elastic force of the return spring, the armature plate 8 slides out of the groove, and the fan and throttle valve are started. The cylinder 9 then drives the sliding blocks 3 and 4 to descend as a whole until the top of the upper housing 10 is submerged in the cooling water tank 1. The microcontroller controller then stops the cylinder. 9. Cold air is blown into the placement slot 12 through the air inlet pipe 15 to cool the porcelain crown in the placement slot 12. After a period of time, the microcontroller controller starts the circulation pump and radiator, and circulates the water in the cooling water tank 1 through the water inlet pipe 17 and the water outlet pipe 18 to ensure that the temperature in the cooling water tank 1 remains at a low temperature, so that the porcelain crown in the placement slot 12 is cooled better. After the porcelain crown is cooled, the microcontroller controller stops the radiator, circulation pump and fan, starts the cylinder 9, drives the sliding block 3 and the sliding block 4 to rise, and then controls the electromagnet 5 to be de-energized and the electromagnet 7 to be energized, so that the sliding block 4 is fixed to the support column 2 and the sliding block 3 is separated from the sliding block 4. The cylinder 9 drives the upper shell 10 between the sliding blocks 4 to rise through the connecting plate, so that the operator can take out the cooled porcelain crown in the placement slot 12.
