One end of the connecting rod assembly 5 is connected to the lead screw nut connector 10, and an extrusion head 8 is arranged at the other end of the connecting rod assembly 5. The extrusion head 8 is arranged in the extrusion cavity 60 and can move up and down in the extrusion cavity 60. The essential oil collection assembly 7 is arranged on the extrusion cylinder 6 for collecting plant essential oil.

[0028] The household plant essential oil extruder provided in this embodiment has a simple structure and is convenient to operate.

[0029] Specifically, it has a small volume, a simple internal structure, and a low cost, which is conducive to popularization and promotion.

[0030] In addition, the lead screw 3, the lead screw nut 4, the lead screw nut connector 10 and the connecting rod assembly 5 are driven by the driving device 2 to drive the extrusion head 8 to move up and down in the extrusion cavity 60, and finally realize the extrusion and extraction of plant essential oils.

[0031] Moreover, since the driving device 2 is used for driving, the operation is relatively simple and efficient, and the user experience is better.

[0032] In this embodiment, the driving device 2 includes a driving motor 21, a speed reducer 22 and a coupling 23 that are connected together in sequence. A control component 9 is arranged on the frame assembly 1, and the driving device 2 is electrically connected to the control component 9. Its structure is simple, the design is reasonable and ingenious. Through the above design, the automatic extrusion and extraction of plant essential oils can be realized, the operation is relatively simple and efficient, the operation intensity of the user can be effectively reduced, and it is beneficial to improve the user experience.

[0033] Furthermore, an upper connecting portion 101 and a lower connecting portion 102 are respectively arranged on the top and bottom of the lead screw nut connector 10. The upper connecting portion 101 is used to connect with the connecting rod assembly 5. A connecting shaft 13 is arranged through the lower connecting portion 102, and load-bearing wheels 14 are respectively arranged at both ends of the connecting shaft 13. Its structure is simple, the design is reasonable and ingenious. Since there is a reaction force acting downward on the lead screw nut 4 and / or the lead screw 3 during the upward extrusion process of the extrusion head 8, the above design is beneficial to improve the load-bearing capacity of the lead screw nut 4 and / or the lead screw 3, avoid the fracture of the lead screw nut 4 and / or the lead screw 3, and thus achieve the purpose of improving the stability and reliability of product use, and can extend the service life of the product.

Its structure is simple, the design is reasonable and ingenious. By arranging the position detection device 15, it can be detected whether the lead screw nut 4 is operating normally, that is, whether the extrusion head 8 is extruding normally. Especially, when the extrusion head 8 cannot continue to extrude and extract plant essential oils upward, at this time, the position detection device 15 detects that the lower connecting portion 102 cannot continue to move forward, and the position detection device 15 will send a signal to the control component 9 to control the driving device 2 to stop operating. It can effectively improve the safety and reliability of product use and effectively avoid accidents.

[0035] In this embodiment, the connecting rod assembly 5 includes a first connecting rod 51 and a second connecting rod 52 that are movably connected together. One end of the first connecting rod 51 is connected to the upper connecting portion 101 of the screw nut connector 10, and the other end is connected to one end of the second connecting rod 52. An extrusion head 8 is provided at the other end of the second connecting rod 52. Its structure is simple, reasonable and ingenious. Through the above design, it is convenient to convert the horizontal movement of the screw nut 4 into the up-and-down extrusion movement of the extrusion head 8.

[0036] Further, an upper fixing plate 161 and a lower fixing plate 162 are provided on the second frame 12 at intervals in the up-and-down direction. The extrusion cylinder 6 is fixedly arranged on the upper fixing plate 161 and the lower fixing plate 162. Its structure is simple, reasonable and ingenious. Through the above design, it is convenient to fix the extrusion cylinder 6 so that it can withstand a large extrusion force, thereby improving the safety and reliability of product use.

[0037] Furthermore, a first heating member and a first temperature sensor are arranged in the second connecting rod 52. The first heating member is used to heat the extrusion head 8; a second heating member and a second temperature sensor are arranged outside the extrusion cylinder 6. The second heating member is used to heat the extrusion cavity 60. The first heating member, the first temperature sensor, the second heating member and the second temperature sensor are all electrically connected to the control assembly 9. Its structure is simple, reasonable and ingenious. By arranging the heating members to heat the extrusion head 8 and the extrusion cavity 60, the plants located in the extrusion cavity 60 can be heated comprehensively, thereby improving the efficiency of extruding and extracting plant essential oils.

[0038] In this embodiment, a sealing ring 17 is arranged between the inner wall of the extrusion head 8 and the extrusion cavity 60. Its structure is simple, reasonable and ingenious. Thereby, the sealing performance of the connection between the extrusion head 8 and the extrusion cavity 60 can be improved, preventing the plant essential oil from flowing downward. The plant essential oil can only be collected by the essential oil collection assembly 7, thereby improving the collection efficiency of the plant essential oil.

[0039] Furthermore, the essential oil collection component 7 includes a collection head 71 which is rotatably connected to the top of the extrusion cylinder 6. A collection chamber 710 is provided on the collection head 71, and the bottom of the collection chamber 710 communicates with the extrusion chamber 60. The cross-section of the collection chamber 710 is funnel-shaped, and a filter screen 18 is provided between the extrusion chamber 60 and the collection chamber 710. Its structure is simple, reasonable and ingenious. When the extrusion head 8 moves upward to extrude and extract the essential oil of plants, the extracted essential oil of plants will enter the collection chamber 710 through the top of the extrusion chamber 60, and thus the collection of the essential oil of plants can be completed. The essential oil of plants in the collection chamber 710 can be scraped away by other tools. In addition, the filter screen 18 provided can prevent impurities from entering the collection chamber 710, and thus the purity of the essential oil of plants collected by the product can be improved to a certain extent.

[0040] The above design is reasonable and ingenious. An essential oil collection channel 712 with a tiny aperture is formed between the extrusion chamber 60 and the collection chamber 710. When the extrusion head 8 moves upward to extrude and extract the essential oil of plants, the extracted essential oil of plants will pass through the top of the extrusion chamber 60 and then enter the collection chamber 710 through the essential oil collection channel 712. At this time, there is a very large pressure in the extrusion chamber 60, and the extruded essential oil of plants is extruded from the filter screen 18 in the extrusion chamber 60 through the high pressure to achieve the effects of filtration and purification.

[0041] Furthermore, a handle 72 is provided on one side of the collection head 71, a rotary connection block 711 is provided on the inner side wall of the collection chamber 710, and a rotary connection groove 62 is provided on the outer side of the top of the extrusion cylinder 6. The collection head 71 is fixed to the top of the extrusion cylinder 6 through the cooperation of the rotary connection block 711 and the rotary connection groove 62. Its structure is simple, reasonable and ingenious. Through the above design, it is convenient to realize the quick installation and disassembly of the essential oil collection component 7, and the connection between the collection head 71 and the extrusion cylinder 6 is reliable and stable, avoiding the situation that the collection head 71 falls off during the extrusion process.

[0042] The essential oil extruder provided in this embodiment drives the lead screw 3, the lead screw nut 4 and the connecting rod assembly 5 through the driving device 2, and further realizes the purpose of driving the extrusion head 8 to move up and down in the extrusion chamber 60, and finally realizes the extrusion and extraction of the essential oil of plants. Compared with the existing bulky hydraulic mechanism or simple manual mechanism for squeezing the essential oil of plants, the essential oil extruder provided in this embodiment has a greater extrusion force and can extract the essential oil of plants with a higher purity.

[0043] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
