Detailed implementation manners

[0031] The following further describes the present invention in detail in conjunction with the accompanying drawings and specific implementation manners, but does not limit the protection scope and application scope of the present invention.

At least two hoses 6 are connected to the inner front side of the upper part of the base 1, and each hose 6 is communicated with the oil tank 2. At least two outlet pipes 7 are connected to and communicated with the inner top of the front side of the base 1. The first baffle 8 is slidably connected to the inner front side of the upper part of the base 1. The first baffle 8 is located above the hose 6. At least two first round holes 9 are opened on the front side of the first baffle 8, and the hose 6 is communicated with the first round hole 9. The first handle 10 is connected to the front side of the first baffle 8. The feeding mechanism 11 is connected to the front part of the base 1, and the feeding mechanism 11 is used to push the essential oil bottle to move. The metering mechanism 12 is connected to the upper front part of the base 1, and the metering mechanism 12 is used to achieve quantitative feeding.

[0034] Refer to Figure 1 and Figure 3 As shown in the figure, the feeding mechanism 11 includes a first support block 1101, a first rotating shaft 1102, a first gear 1103, a second rotating shaft 1104, a second support block 1105, a first connecting rod 1106, a first push rod 11061, a first fixing block 1107, a double-shaft motor 1108, a third rotating shaft 1109, a second gear 1110 and a fourth rotating shaft 1111. Two first support blocks 1101 are welded to the inner front side of the middle part of the base 1. The upper parts of the sides of the two first support blocks 1101 close to each other are rotatably connected to the first rotating shaft 1102. The first gears 1103 are connected to the two first rotating shafts 1102 by keys. The eccentric positions of the sides of the two first gears 1103 close to each other are rotatably connected to the second rotating shaft 1104. Two second support blocks 1105 are slidably connected to the lower part of the front side of the base 1. The first connecting rods 1106 are rotatably connected to the two second support blocks 1105. The two first connecting rods 1106 are fixedly connected to the second rotating shaft 1104. A first push rod 11061 is welded between the two second support blocks 1105, which is used to push the essential oil bottle to move. The first fixing block 1107 is connected to the lower part of the front side of the outside of the oil tank 2. The double-shaft motor 1108 is connected to the inner side of the first fixing block 1107 by bolts. The two output shafts of the double-shaft motor 1108 are connected to the third rotating shaft 1109 by couplings. The second gears 1110 are connected to the ends of the two third rotating shafts 1109 away from each other by keys. The two first gears 1103 are meshed with the second gears 1110. The eccentric positions of the sides of the two second gears 1110 away from each other are rotatably connected to the fourth rotating shaft 1111.

[0035] Refer to Figure 1 and Figure 4As shown in the figure, the metering mechanism 12 includes a second baffle 1201 and a second handle 1203. The second baffle 1201 is slidably connected to the inner front side of the upper part of the base 1. The second baffle 1201 is used to achieve metered feeding. The second baffle 1201 is located at the bottom of the hose 6. At least two second round holes 1202 are opened in the middle of the second baffle 1201. The movement of the second round holes 1202 is communicated with the hose 6. The second handle 1203 is connected to the front side of the second baffle 1201.

[0036] When it is necessary to fill the essential oil, the staff first rotates the movable plug 4 to open it. The staff connects the external oil pipe to the oil inlet pipe 3. The essential oil then flows into the fuel tank 2 through the oil inlet pipe 3. The essential oil in the fuel tank 2 then flows into the hose 6. When the fuel tank 2 is filled with sufficient essential oil, the staff removes the external oil pipe from the oil inlet pipe 3. The staff then rotates the movable plug 4 in the reverse direction. Then the staff orderly places the essential oil bottles inside the inner front side of the middle part of the base 1. The staff slides the first baffle 8 backward by pushing the first handle 10. The first round hole 9 is no longer communicated with the hose 6. At the same time, the staff pulls the second baffle 1201 forward by pulling the second handle 1203. The hose 6 is connected to the oil outlet pipe 7. Thus, the essential oil in the hose 6 flows out through the oil outlet pipe 7 into the essential oil bottle, so as to achieve the purpose of metered feeding of the essential oil. At the same time, the staff starts the double-shaft motor 1108. The output shaft of the double-shaft motor 1108 drives the third rotating shaft 1109 to rotate through the coupling. The rotation of the third rotating shaft 1109 drives the second gear 1110 to rotate. The second gear 1110 meshes with the first gear 1103. The rotation of the first gear 1103 causes the second rotating shaft 1104 to rotate. The second rotating shaft 1104 drives the first connecting rod 1106 to rotate backward. Thus, the second support block 1105 drives the first push rod 11061 to slide backward. The first push rod 11061 pushes the essential oil bottle to slide backward. Thus, there is no need for manual movement of the essential oil bottle by the staff, reducing the labor intensity of the staff. When the essential oil bottle is pushed to the rearmost part by the first push rod 11061, the staff removes the essential oil bottle for sealing. When filling the essential oil, the staff repeats the above operations to achieve the purpose of metered feeding. When the essential oil filling is completed, the staff turns off the double-shaft motor 1108 to stop the operation.

[0037] Embodiment 2

[0038] On the basis of Embodiment 1, refer to Figure 1 、 Figure 5 and Figure 6As shown, it further includes a material pushing mechanism 13. The material pushing mechanism 13 is used to push the essential oil to flow. The material pushing mechanism 13 includes a telescopic frame 1301, a push plate 1304, a second push rod 1305, a second connecting rod 1306, a fifth rotating shaft 1307, a third connecting rod 1308, and a third handle 1309. Two telescopic frames 1301 are connected to the inner bottom of the fuel tank 2. Three push plates 1304 are welded at intervals on the top of each of the two telescopic frames 1301. The push plates 1304 are used to push the essential oil to flow. The second push rods 1305 are connected to the rear sides of the two telescopic frames 1301. A second connecting rod 1306 is connected between the two second push rods 1305. The fifth rotating shafts 1307 are connected to the left and right sides of the second connecting rod 1306. The third connecting rods 1308 are rotatably connected to the two fifth rotating shafts 1307. The two third connecting rods 1308 are fixedly connected to the fourth rotating shaft 1111. The middle of the top of the second connecting rod 1306 is connected to the third handle 1309.

[0039] When the dual-axis motor 1108 operates, the second gear 1110 rotates to drive the fourth rotating shaft 1111 to rotate. While the fourth rotating shaft 1111 rotates, it drives the third connecting rod 1308 to move forward. When the second gear 1110 rotates 180 degrees, the third connecting rod 1308 drives the second connecting rod 1306 to move forward through the fifth rotating shaft 1307. The forward movement of the second connecting rod 1306 causes the second push rod 1305 to move forward, and further causes the second push rod 1305 to push the telescopic frame 1301 to contract. The contraction of the telescopic frame 1301 drives the push plate 1304 to approach, thereby pushing the essential oil to flow. When the second gear 1110 rotates 360 degrees, the third connecting rod 1308 moves backward to reset, causing the fifth rotating shaft 1307 to drive the second connecting rod 1306 to move backward. The backward movement of the second connecting rod 1306 causes the second push rod 1305 to move backward to reset, and further causes the second push rod 1305 to pull the telescopic frame 1301 to stretch. The stretching of the telescopic frame 1301 drives the push plate 1304 to move away. This cycle is repeated multiple times to accelerate the flow of the essential oil into the hose 6.

[0040] Refer to Figure 1 、 Figure 7 and Figure 8As shown in the figure, it further includes a discharging mechanism 14, which is used to assist in the transportation of essential oil bottles. The discharging mechanism 14 includes a slide rail 1401, a slider 1402, a second fixing block 1403, a servo motor 1404, a third fixing block 1405, a sixth rotating shaft 1406, a pulley 1407 and a flat belt 1408. Slide rails 1401 are connected to the left and right sides inside the lower part of the base 1. A slider 1402 is slidably connected between the two slide rails 1401. A second fixing block 1403 is welded to the right front side of the top of the slider 1402. A servo motor 1404 is connected to the inside of the second fixing block 1403 by bolts. A third fixing block 1405 is welded to the left front side of the top of the slider 1402. Third fixing blocks 1405 are also welded to the left and right sides at the back of the top of the slider 1402. A sixth rotating shaft 1406 is rotatably connected between the two third fixing blocks 1405 at the back. The output shaft of the servo motor 1404 passes through the second fixing block 1403 and is also connected to the sixth rotating shaft 1406 through a coupling. The sixth rotating shaft 1406 at the front is rotatably connected to the third fixing block 1405 at the front. Pulleys 1407 are connected to the two sixth rotating shafts 1406 by keys. A flat belt 1408 is connected to the two pulleys 1407. The flat belt 1408 is used to assist in the transportation of essential oil bottles.

[0041] When the essential oil bottle is filled with essential oil, the staff needs to transfer the essential oil bottle to the next process. The staff starts the servo motor 1404. The output shaft of the servo motor 1404 drives the sixth rotating shaft 1406 at the front to rotate through a coupling. The rotation of the sixth rotating shaft 1406 at the front causes the pulley 1407 at the front to rotate. The pulley 1407 at the front drives the pulley 1407 at the back to rotate through the flat belt 1408. Then the staff pushes the slider 1402 to slide backward through the slide rail 1401. When the essential oil bottle falls off the base 1, the flat belt 1408 rotates to transport the essential oil bottle, so as to achieve the purpose of quickly discharging the essential oil bottle. When the essential oil filling is completed, the staff turns off the servo motor 1404 to stop the operation. Then the staff pushes the slider 1402 to slide forward through the slide rail 1401 to reset.

[0042] Refer to Figure 1 、 Figure 9 and Figure 10 As shown in the figure, it further includes a leak prevention mechanism 15, which prevents essential oil from leaking. The leak prevention mechanism 15 includes a first support rod 1501, an elastic member 1502 and a sleeve 1503. Two first support rods 1501 are welded to the front side of the inner bottom of the base 1. A sleeve 1503 is slidably connected between the two first support rods 1501. The sleeve 1503 is located below the hose 6. Elastic members 1502 are connected between the left and right sides at the back of the sleeve 1503 and the first support rods 1501. The two elastic members 1502 are sleeved on the first support rods 1501. The elastic member 1502 is a spring.

[0043] Refer to Figure 1 、 Figure 11 and Figure 12 As shown, it further includes an extrusion mechanism 16. The extrusion mechanism 16 is used to extrude the hose 6. The extrusion mechanism 16 includes a second support rod 1601, a third push rod 1602, a fourth push rod 1603, a clamping block 1604, an extrusion block 1605 and a push block 1606. A second support rod 1601 is welded between the front lower parts of the two second push rods 1305. A third push rod 1602 is welded to the front side of the second support rod 1601. Two fourth push rods 1603 are connected to the bottom of the second support rod 1601. Two clamping blocks 1604 are welded to the front side of the top of the third push rod 1602, and two clamping blocks 1604 are also welded to the front side of the bottom of the third push rod 1602. The two clamping blocks 1604 at the top are fixedly connected to the first baffle 8, and the two clamping blocks 1604 at the bottom are fixedly connected to the second baffle 1201. At least eight extrusion blocks 1605 are connected to the front side of the third push rod 1602. The extrusion blocks 1605 are used to extrude the hose 6. The movements of the two extrusion blocks 1605 are in contact with the hose 6. Push blocks 1606 are connected to the front sides of the two fourth push rods 1603. The movements of the two push blocks 1606 are in contact with the sleeve 1503.

[0044] When filling the essential oil, the staff first places the essential oil bottle under the sleeve 1503. When the second push rod 1305 moves forward, the second push rod 1305 drives the second support rod 1601 to move forward, thereby making the third push rod 1602 slide forward. The third push rod 1602 slides forward and drives the extrusion block 1605 to move forward and contact with the hose 6, and then the extrusion block 1605 squeezes the hose 6, thereby achieving the purpose of quickly squeezing out the essential oil. At the same time, under the action of the block 1604, the block 1604 drives the first baffle 8 and the second baffle 1201 to slide forward. The first baffle 8 slides forward so that the first circular hole 9 is no longer connected with the hose 6. The second baffle 1201 slides forward so that the oil outlet pipe 7 is connected with the hose 6. The second support rod 1601 moves forward and drives the fourth push rod 1603 to slide forward. The fourth push rod 1603 slides forward and drives the push block 1606 to move forward, and then the push block 1606 moves to contact with the sleeve 1503. The block 1606 then pushes the sleeve 1503 to slide downward under the guidance of the guide rod, the elastic member 1502 is deformed, and the sleeve 1503 slides downward to be clamped to the upper part of the essential oil bottle, thereby preventing the essential oil from leaking out during filling and causing waste. When the second push rod 1305 moves backward, the third push rod 1602 slides backward and resets to drive the extrusion block 1605 to move backward and disengage from the hose 6. At the same time, the clamping block 1604 drives the first baffle 8 and the second baffle 1201 to slide backward and reset. The first baffle 1305 moves backward and the third push rod 1602 moves backward and resets. The plate 8 is reset so that the first circular hole 9 is connected to the hose 6, the second baffle 1201 is reset so that the oil outlet pipe 7 is no longer connected to the hose 6, the second support rod 1601 is reset so that the fourth push rod 1603 is reset, and the reset of the fourth push rod 1603 drives the push block 1606 to move backward and reset, and then the push block 1606 is reset and disengaged from the sleeve 1503. Since the elastic member 1502 is a spring, under the action of the elastic member 1502, the sleeve 1503 slides upward and resets and disengages from the essential oil bottle.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
