DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 6 As shown, the utility model provides a thermal conductive gel feeding device, including a bracket 1, a tank body 2 is provided on the bracket 1, a partition 3 is slidably matched in the tank body 2, a planetary frame shell 12 with a thin-walled structure is rotatably installed on the partition 3, a plurality of planetary shafts 13 are rotatably installed on the planetary frame shell 12, a driving structure is provided on the partition 3 to drive the planetary shafts 13 to rotate, and the driving structure includes a motor 4, the motor 4 is fixedly connected to the partition 3, a central gear 9 is fixedly connected to the output shaft of the motor 4, a planetary gear 10 is fixedly connected to the planetary shaft 13, the central gear 9 matches the planetary gear 10, and a ring gear 11 is fixedly connected to the partition 3, and the ring gear 11 matches the planetary gear 10.

[0024] When the device is in use, the motor 4 is started, and the motor 4 drives the central gear 9 to rotate. The rotation of the central gear 9 drives multiple planetary gears 10 to rotate. Because the planetary gears 10 are meshed with the ring gear 11 and the ring gear 11 is in a fixed state, the planetary gears 10 will also revolve around the central gear 9 during the rotation process.

[0025] As for the rotation of the planetary gear 10, the planetary gear 10 will drive the planetary shaft 13 to rotate;

[0026] As for the revolution of the planetary gear 10 , the revolution of the planetary gear 10 will drive the planetary shaft 13 to revolve, and the revolution of the planetary shaft 13 will drive the planetary carrier housing 12 to rotate on the partition plate 3 .

[0027] like Figure 2-6As shown, a first stirring blade 15 is fixedly connected to the planetary shaft 13, a plurality of transmission shafts 17 are radially rotatably mounted on the planetary frame housing 12, a second stirring blade 18 is fixedly connected to one end of the transmission shaft 17, and a second bevel gear 16 is fixedly connected to the other end, a first bevel gear 14 is fixedly connected to the planetary shaft 13, and the first bevel gear 14 matches the second bevel gear 16.

[0028] During the rotation and revolution of the planetary shaft 13 , the planetary shaft 13 drives the first stirring blade 15 to rotate and revolve, so that the first stirring blade 15 stirs and mixes the thermal conductive gel in the tank body 2 .

[0029] During the rotation of the planetary shaft 13, the planetary shaft 13 drives the first bevel gear 14 to rotate, the rotation of the first bevel gear 14 drives the second bevel gear 16 to rotate, the rotation of the second bevel gear 16 drives the transmission shaft 17 to rotate, and the transmission shaft 17 drives the second stirring blade 18 to rotate, thereby improving the stirring quality.

[0030] like Figure 2 As shown, when the first stirring blade 15 rotates, the axis is parallel to the axis of the tank body 2, and when the second stirring blade 18 rotates, the axis is perpendicular to the axis of the tank body 2. Therefore, the first stirring blade 15 and the second stirring blade 18 rotate inside the tank body 2 and can stir the tank body 2 from the axial and radial directions, thereby stirring the thermal conductive gel in the tank body 2 in multiple directions to improve the stirring quality.

[0031] like Figure 2-4 As shown, a screw rod 6 is rotatably mounted on the partition 3, a nut seat 23 is fixedly connected to the tank body 2, the nut seat 23 is threadedly matched with the screw rod 6, a first pulley 5 is fixedly connected to the output shaft of the motor 4, a second pulley 7 is fixedly connected to the screw rod 6, and a belt 8 is mounted on the first pulley 5 and the second pulley 7 in cooperation with each other.

[0032] After the motor 4 is started, the motor 4 will drive the first pulley 5 to rotate. The rotation of the first pulley 5 will drive the second pulley 7 to rotate through the belt 8. The rotation of the second pulley 7 will drive the screw 6 to rotate. Since the screw 6 is threadedly engaged in the nut seat 23 and the nut seat 23 is in a fixed state, the screw 6 will move axially along the tank body 2 during its rotation. The screw 6 will drive the partition 3 to move axially in the tank body 2 during its axial movement, thereby squeezing the thermal conductive gel in the tank body 2 to improve the efficiency of discharging the thermal conductive gel in the tank body 2.

[0033] like Figure 5-6As shown, a slide tube 19 is radially fixed to the planetary carrier housing 12, a slide rod 20 is slidably fitted inside the slide tube 19, a scraper 22 is fixed to the slide rod 20, and a first spring 21 is sleeved on the slide rod 20 to apply elastic force to the scraper 22. Since the first spring 21 is always in a compressed state, the scraper 22 is always against the inner wall of the tank body 1 under the elastic force of the first spring 21.

[0034] During the rotation of the planetary carrier housing 12, the scraper 22 will be driven to rotate synchronously. Since the scraper 22 is pressed against the inner wall of the tank body 2 under the elastic force of the first spring 21, the thermal conductive gel attached to the inner wall of the tank body 2 can be scraped off during the rotation of the scraper 22 to prevent part of the thermal conductive gel from being attached to the inner wall of the tank body 2 and being unable to be stirred and mixed.

[0035] like Figure 2 As shown, a support 101 is fixedly connected to the bracket 1 , and a support tube 102 is slidably matched on the support 101 . A second spring 103 is arranged in the support tube 102 to apply elastic force to the support 101 .

[0036] During the operation of the motor 4 , a certain vibration is generated, and the vibration is buffered and protected by the second spring 103 , thereby slowing down the wear rate of the device connection to increase the service life.

[0037] The working principle and use process of this utility model:

[0038] When using this device:

[0039] The thermal conductive gel and additives are fed into the tank 2 through the feed pipe 201 , and then the motor 4 is started.

[0040] The motor 4 drives the central gear 9 to rotate, and the rotation of the central gear 9 drives the multiple planetary gears 10 to rotate. Because the planetary gears 10 are meshed with the ring gear 11 and the ring gear 11 is in a fixed state, the planetary gears 10 will also revolve around the central gear 9 during the rotation process.

[0041] As for the rotation of the planetary gear 10, the planetary gear 10 will drive the planetary shaft 13 to rotate;

[0042] As for the revolution of the planetary gear 10 , the revolution of the planetary gear 10 will drive the planetary shaft 13 to revolve, and the revolution of the planetary shaft 13 will drive the planetary carrier housing 12 to rotate on the partition plate 3 .

[0043] During the rotation and revolution of the planetary shaft 13 , the planetary shaft 13 drives the first stirring blade 15 to rotate and revolve, so that the first stirring blade 15 stirs and mixes the thermal conductive gel in the tank body 2 .

[0044] During the rotation of the planetary shaft 13, the planetary shaft 13 drives the first bevel gear 14 to rotate, the rotation of the first bevel gear 14 drives the second bevel gear 16 to rotate, the rotation of the second bevel gear 16 drives the transmission shaft 17 to rotate, and the transmission shaft 17 drives the second stirring blade 18 to rotate, thereby improving the stirring quality.

[0045] like Figure 2 As shown, when the first stirring blade 15 rotates, the axis is parallel to the axis of the tank body 2, and when the second stirring blade 18 rotates, the axis is perpendicular to the axis of the tank body 2. Therefore, the first stirring blade 15 and the second stirring blade 18 can stir the inside of the tank body 2 from the axial and radial directions, thereby stirring the thermal conductive gel in the tank body 2 in multiple directions to improve the stirring quality.

[0046] The motor 4 will drive the first pulley 5 to rotate, and the rotation of the first pulley 5 will drive the second pulley 7 to rotate through the belt 8, and the rotation of the second pulley 7 will drive the screw 6 to rotate. Since the screw 6 is threadedly engaged in the nut seat 23 and the nut seat 23 is in a fixed state, the screw 6 will move axially along the tank body 2 during its rotation, and the screw 6 will drive the partition 3 to move axially in the tank body 2 during its axial movement, thereby squeezing the thermal conductive gel in the tank body 2. After the thermal conductive gel is stirred, it is discharged from the discharge pipe 202 under the squeezing action of the partition 3 for loading, so as to improve the loading efficiency of the thermal conductive gel in the tank body 2.

[0047] During the rotation of the planetary carrier housing 12, the scraper 22 will be driven to rotate synchronously. Since the scraper 22 is pressed against the inner wall of the tank body 2 under the elastic force of the first spring 21, the thermal conductive gel attached to the inner wall of the tank body 2 can be scraped off during the rotation of the scraper 22 to prevent part of the thermal conductive gel from being attached to the inner wall of the tank body 2 and being unable to be stirred and mixed.

[0048] During the operation of the motor 4 , a certain vibration is generated, and the vibration is buffered and protected by the second spring 103 , thereby slowing down the wear rate of the device connection to increase the service life.
