It is a mineral composed of carbon, a naturally occurring particle composed of a single element, and an allotrope of carbon. Graphite can be used to form synthetic diamond under high temperature and pressure, which is also a precious gemstone. Microwave plasma CVD uses a microwave generator to introduce microwaves into a reactor via a waveguide and isolator, along with a mixture of CH4 and H2 gases. Under microwave excitation, a glow discharge is generated in the reaction chamber, ionizing the molecules of the reactant gases and producing plasma, which deposits a diamond film on a substrate.

[0003] In the use of existing technology, the temperature inside the synthesis box is high, which can easily affect the motor and cause damage. Therefore, heat insulation protection is required. However, the motor is not convenient to dissipate heat during use after protection, so heat dissipation protection is required. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-5 The present invention provides the following technical solution: a high-efficiency diamond synthesis device based on MPCVD, including a base 6, a synthesis box 1 installed on the upper end of the base 6, a motor 4 installed at the lower end of the synthesis box 1, a heat insulation component 5 installed on the outside of the motor 4, a heat dissipation component 7 installed inside the base 6 at the position corresponding to the motor 4, a threaded rod 3 connected to the output end of the motor 4, a threaded tube 2 sleeved on the surface of the threaded rod 3, a base body 10 connected to the upper end of the threaded tube 2, a temperature sensing structure 9 installed inside the base body 10, and a cable storage structure 8 provided on the inner side surface of the synthesis box 1;

[0025] The heat insulation component 5 includes a protective box 51. The protective box 51 is provided on the outside of the motor 4. An installation structure 52 is provided between the protective box 51 and the synthesis box 1. A vacuum heat insulation plate 54 is connected to the inner surface of the protective box 51. A heat insulation soft felt 53 is pasted on the surface of the vacuum heat insulation plate 54.

[0026] Specifically, the mounting structure 52 includes a mounting ear plate 521. The mounting ear plate 521 is fixed to the lower side surface of the protective box 51. The mounting ear plate 521 and the composite box 1 have threaded holes 524 inside, and a screw 525 is connected inside the threaded holes 524.

[0027] By adopting the above technical solution, the screw 525 passes through the mounting ear plate 521 and is threaded into the threaded hole 524, which can facilitate the installation and fixing of the protective box 51.

[0028] Specifically, a positioning block 523 is fixed to the bottom of the mounting ear plate 521, and a positioning groove 522 is provided inside the synthesis box 1 at a position corresponding to the positioning block 523.

[0029] By adopting the above technical solution, the positioning block 523 is engaged with the positioning groove 522, which can position the protective box 51 and make the two sets of threaded holes 524 accurately correspond.

[0030] Specifically, a fire-resistant sponge pad 55 is connected to the upper end of the protective box 51, and a sealing soft cover 56 is wrapped around the outer surface of the fire-resistant sponge pad 55.

[0031] By adopting the above technical solution, the fire-resistant sponge pad 55 and the sealing soft cover 56 work together to provide sealing and heat insulation protection for the output shaft of the motor 4.

[0032] In this embodiment, the synthesis box 1 is installed on the upper part of the base 6. The temperature sensing structure 9 senses the temperature of the upper part of the base body 10 and transmits the temperature data to the control host. When the temperature is higher or lower than the set value, the control host controls the motor 4 to work, and the threaded rod 3 rotates to drive the threaded tube 2 to rise and fall, thereby controlling the rise and fall movement of the base body 10. This controls the distance between the base body 10 and the microwave plasma, thereby controlling the diamond growth temperature on the surface of the base body 10, thus achieving efficient diamond synthesis through MPCVD. The cable in the cable storage structure 8 is energized. The protective box 51 is installed on the outside of the motor 4 through the installation structure 52. The vacuum heat insulation plate 54 and heat insulation soft felt 53 inside can play a double heat insulation role, thereby protecting the motor 4 and preventing its surface temperature from being too high. The screw 525 passes through the mounting ear plate 521 and is threaded into the threaded hole 524, which can easily install and fix the protective box 51. The positioning block 523 is engaged with the positioning groove 522, which can position the protective box 51 and make the two sets of threaded holes 524 accurately correspond. The fire-resistant sponge pad 55 cooperates with the sealing soft cover 56 to provide sealing and heat insulation protection for the output shaft of the motor 4.

[0033] Example 2

[0034] The difference between this embodiment and Embodiment 1 is that: the heat dissipation assembly 7 includes a heat dissipation groove 71, and the heat dissipation groove 71 is provided inside the synthesis box 1 and the base 6 at a position corresponding to the motor 4. A heat dissipation plate 75 is connected to the bottom of the motor 4 through thermally conductive adhesive 76, and a heat dissipation fin 73 is fixed at the bottom of the heat dissipation plate 75 and inside the heat dissipation groove 71.

[0035] By adopting the above technical solution, when the motor 4 is working, the heat generated is transferred to the surface of the heat sink 75 through the thermally conductive adhesive 76, and then rapidly diffused through the heat sink 73 in the heat sink 71, achieving a good heat dissipation effect.

[0036] Specifically, a mounting frame 74 is installed at the lower end of the heat dissipation slot 71, and a dustproof mesh 72 is installed inside the mounting frame 74.

[0037] By adopting the above technical solution, the dustproof net 72 inside the mounting frame 74 can achieve the effect of dustproof protection.

[0038] Specifically, ventilation slots 78 are provided inside the base 6 and on both sides of the heat dissipation groove 71, and sealing covers 77 are connected inside the ventilation slots 78.

[0039] By adopting the above technical solution, when the temperature inside the heat dissipation slot 71 is high, the sealing cover 77 can be removed and cold air can be blown into the ventilation slot 78, which can improve the heat dissipation effect on the motor 4.

[0040] In this embodiment, when the motor 4 is working, the heat generated is transferred to the surface of the heat sink 75 through the thermally conductive adhesive 76, and then quickly diffused through the heat sink 73 in the heat sink 71, which achieves a good heat dissipation effect. The dustproof net 72 in the mounting frame 74 can play a dustproof protection role. When the temperature in the heat sink 71 is high, the sealing cover 77 can be removed and cold air can be blown into the ventilation slot 78, which can improve the heat dissipation effect of the motor 4.

[0041] The structure and working principle of the cable storage structure 8, which consists of a first electrical connection wire and a cable storage box, and the temperature sensing structure 9, which consists of an infrared temperature sensor, a glass protective cover, an annular sealing silicone pad, a first sealing silicone ring, and a second sealing silicone ring, have been disclosed in Chinese patent application number 202420500209.3, which discloses a high-efficiency diamond synthesis device based on MPCVD. The working principle of the cable storage structure 8 is that during the lifting and moving of the base body 10, the longer first electrical connection wire can be pulled into the cable storage box for storage under the action of the movable sleeve and the compression spring. The working principle of the temperature sensing structure 9 is that the infrared temperature sensor monitors the temperature and transmits the temperature data to the control host, and the glass protective cover protects it.

[0042] The working principle and usage process of this utility model are as follows: When using this utility model, the synthesis box 1 is installed on the upper end of the base 6. The temperature sensing structure 9 senses the temperature of the upper end of the base body 10 and transmits the temperature data to the control host. When the temperature is higher or lower than the set value, the control host controls the motor 4 to work. The threaded rod 3 rotates, driving the threaded tube 2 to rise and fall, thereby controlling the rise and fall movement of the base body 10. This controls the distance between the base body 10 and the microwave plasma, thus controlling the diamond growth temperature on the surface of the base body 10, thereby achieving efficient diamond synthesis through MPCVD. The cable in the cable storage structure 8 is energized. The protective box 51 is installed on the outside of the motor 4 through the mounting structure 52. The vacuum insulation plate 54 and the heat insulation felt 53 inside provide a double heat insulation effect, thereby protecting the motor 4. To protect the surface of the motor 4 from overheating, the screw 525 passes through the mounting ear plate 521 and is threaded into the threaded hole 524, which facilitates the installation and fixation of the protective box 51. The positioning block 523 engages with the positioning groove 522 to position the protective box 51 and ensure that the two sets of threaded holes 524 are accurately aligned. The fire-resistant sponge pad 55 and the sealing soft cover 56 work together to provide sealing and heat insulation protection for the output shaft of the motor 4. When the motor 4 is working, the heat generated is transferred to the surface of the heat sink 75 through the thermally conductive adhesive 76, and then quickly diffused through the heat sink 73 in the heat sink 71, which achieves a good heat dissipation effect. The dustproof net 72 in the mounting frame 74 can provide dust protection. When the temperature inside the heat sink 71 is high, the sealing cover 77 can be removed to blow cold air into the ventilation groove 78, which can improve the heat dissipation effect of the motor 4.
