Description

Technical Field

[0001] The invention relates to the technical field of air purification, and in particular to a negative ion plant essence extraction device and a preparation method. Background Art

[0002] Negative ion essence is an environmentally friendly and healthy product with multiple functions. It releases negative oxygen ions and uses nano-plant extraction technology to provide air purification, formaldehyde removal, antibacterial and other effects for indoor and car environments. The main ingredients of negative ion essence generally include ion water, nano-silica sol, nano-silver, and extracts of plants such as pine needles, cactus, and tea. These ingredients work together to give the product multiple functions. As the core part of the negative ion essence, plant extracts are usually extracted by distillation, that is, using water vapor to evaporate the volatile components in the plant, and then condensing them into liquid through condensation, and finally separating the oil and water to obtain the plant extract.

[0003] The patent with publication date of February 23, 2024 and announcement number CN220513473U discloses a high-efficiency plant essence extraction device, including a tank body, a support block is fixedly installed on the surface inside the tank body, a placement groove is arranged inside the tank body, a side retaining ring is fixedly installed on the end face of the placement groove, a clamping block is fixedly arranged on the bottom surface at both ends of the side retaining ring, a clamping groove is arranged on the top surface of the support block, the clamping block is installed in the clamping groove, an inner retaining ring is fixedly arranged at the middle end of the placement groove, a stirring rod is arranged at the middle end of the tank body, the stirring rod passes through the inner retaining ring, and a scraper is fixedly arranged on the surface of the stirring rod close to the bottom; the utility model is installed in the clamping groove by the clamping block, which is convenient for the installation and disassembly of the placement groove, convenient for daily cleaning and replacement of the placement groove, and improves the processing quality; and the scraper can clean the plant liquid on the bottom surface of the placement groove to prevent impurities from sticking to the surface of the bottom of the placement groove.

[0004] However, the quality of different plant raw material essences will be affected by factors such as the water vapor temperature and distillation time during the distillation process. The extraction of each plant raw material essence has a theoretical optimal temperature range. Inappropriate distillation temperature will lead to low extraction efficiency. The above scheme takes into account that the plants are placed on the surface of the filter plate inside the distillation barrel, but after work, many impurities and mucus will remain on the surface of the filter plate, which is inconvenient to clean, affecting the subsequent processing quality and other problems. These problems have been solved, but it ignores that the main ingredients in each plant essence are different, and the physical and chemical properties often have large differences. They are highly sensitive to temperature, and excessively high temperatures may destroy these ingredients. Therefore, it is very necessary to control the temperature of the water vapor passing through the plant raw materials to achieve the extraction of high-quality plant essences under high-efficiency conditions.

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0039] In order to improve the problems in the related art that the main components of plant essences have different temperature tolerances, excessively high temperatures may destroy these components, and the water vapor temperature cannot be controlled, resulting in low extraction efficiency and quality of essences of different plant and flower species during the distillation process, the embodiments of the present application provide the following solution.

[0040] Example 1, please refer to Figure 1 as well as Figure 2 The embodiment of the present application provides a negative ion plant essence extraction device, comprising: a distillation mechanism 1, a conduit 4, a condensation mechanism 2 and a separator 3, wherein the distillation mechanism 1 comprises an evaporation component 11, a control component 12, a stirring component 13, a placement plate 14, a tank body 15 and a tank cover 16, wherein the condensation mechanism 2 is arranged on the separator 3, the tank body 15 is fixedly connected to the evaporation component 11, the tank cover 16 is movably connected to the tank body 15, one end of the conduit 4 is connected to an end of the tank cover 16 away from the tank body 15, and the other end of the conduit 4 is connected to an end of the condensation mechanism 2 away from the separator 3, the placement plate 14 is arranged in the tank body 15 and abuts against the inner wall of the tank body 15, and a plurality of through holes are opened in the middle of the placement plate 14 for water vapor to pass through.

[0041] See also Figure 2 as well as Figure 4 The embodiment of the present application provides a negative ion plant essence extraction device, the evaporation component 11 includes a water reservoir 111, a magnetron 112, a water level detection column 113, a first water inlet 114 and a first water outlet 115, the water reservoir 111 is provided with a steam outlet 116, the magnetron 112 is arranged in the pool wall of the water reservoir 111, the water level detection column 113 is arranged on the water reservoir 111 and abuts against the pool wall of the water reservoir 111, the first water inlet 114 is opened at the high point of the water reservoir 111, the high point is slightly higher than the horizontal line where the maximum detection limit of the water level detection column 113 is located, the first water outlet 115 is opened at the low point of the water reservoir 111, and the side of the first water outlet 115 away from the steam outlet 116 is tangent to the plane where the bottom of the water reservoir 111 is located.

[0042] With such arrangement, during the process of generating water vapor, the magnetron 112 in the wall of the water reservoir 111 can generate microwaves, which act on water molecules to cause them to vibrate at high frequency to generate heat, thereby causing the water to boil and evaporate quickly to generate water vapor. The water level detection column 113 located at the edge of the water reservoir 111 has multiple sensors on it, which can detect the water level in the water reservoir 111 in real time to prevent the situation where the water evaporates without being known. The water inlet is slightly higher than the horizontal line of the maximum detection limit of the water level detection column 113, which can effectively avoid excessive water addition resulting in no water. There is enough space for water vapor to stay. When the water in the water reservoir 111 is replenished, water flows into the water reservoir 111 through the first water inlet 114. When water needs to be discharged, water flows out through the first water outlet 115. Since the first water outlet 115 is tangent to the plane where the bottom of the water reservoir 111 is located, water can be discharged from the water reservoir 111 as much as possible. Moreover, the first water outlet 115 and the first water inlet can be connected to high-pressure and high-temperature resistant valves, which ensures the airtightness of the water reservoir 111 while making it more convenient to add and discharge water.

[0043] See also Figure 1 as well as Figure 2 The embodiment of the present application provides a negative ion plant essence extraction device, the control component 12 includes an intelligent safety valve 121, a temperature sensor 124, a condenser 122, a cooling pipe 123 and a computer control screen 125, the intelligent safety valve 121 is bolted to the steam outlet 116, the temperature sensor 124 is fixedly connected to the placement plate 14, the condenser 122 is abutted against the outer wall of the water reservoir 111, the cooling pipe 123 is arranged in the tank body 15, in a spiral ascending shape, and passes through the tank body 15 to be movably connected to the condenser 122 to form a closed loop, the computer control screen 125 is arranged on the water reservoir 111 through a bracket, and is electrically connected to the intelligent safety valve 121, the magnetron 112, the temperature sensor 124 and the condenser 122.

[0044] With such a configuration, the threshold of the intelligent safety valve 121 can be controlled by the computer control screen 125. Before the intelligent safety valve 121 is opened, the water reservoir 111 is a closed space, and the water inside it is constantly boiling and generating water vapor, causing the internal pressure to increase. When the pressure reaches the set threshold, the intelligent safety valve 121 senses the pressure change, the valve opens, and water vapor enters the tank body 15. At this time, the computer control screen 125 receives the valve opening signal fed back by the intelligent safety valve 121, calculates and automatically adjusts the power of the magnetron 112, and changes the water vapor generation. The speed is set so that the amount of water vapor generated per unit time is equal to the amount of water vapor entering the tank body 15 per unit time, so as to achieve a dynamic balance of water vapor. In this way, a continuous flow of water vapor can enter the tank body 15, contact with the plants on the placement tray 14, and drive the plant essence into the condensation system. Since the temperature sensor 124 is fixedly connected to the placement tray 14, the measured temperature can be as close as possible to the temperature of the water vapor passing through the plants on the placement tray 14. By transmitting the temperature information here to the computer control screen 125, the parameters can be selected to adjust the water vapor temperature according to the temperature information displayed on the computer control screen 125. Different plants contain different types and contents of chemical components, and these chemical components have different boiling points and volatilities. Therefore, during the distillation process, the water vapor temperature needs to be adjusted to a range suitable for the extraction of specific plant essences. Too low a temperature may result in the loss of effective ingredients, and too high a temperature may result in the destruction of effective ingredients. When the water vapor temperature is high, the parameters are selected on the computer control screen 125 to control the cooling of the condenser 122. The cooling pipe 123 forming a closed loop with the condenser 122 is spirally arranged in the steam distillation chamber. The contact area between the cooling tube 123 and the water vapor is increased in the space between the steam regulating ring and the placement plate 14, and more high-temperature water vapor exchanges heat with the low-temperature cooling tube 123, thereby reducing the temperature of the water vapor. When the water vapor temperature does not meet the requirements, the threshold of the intelligent safety valve 121 can be increased through the computer control screen 125, and the power of the magnetron 112 can be increased to increase the water vapor temperature. In addition, the computer control screen 125 is equipped with an automatic cut-off program. When the water vapor temperature is higher than the set value for a long time and is difficult to decrease, the program is started to terminate the operation of the instrument.

[0045] See also Figure 2 , Figure 5 , Figure 6 as well as Figure 7The embodiment of the present application provides a negative ion plant essence extraction device, the stirring component 13 includes a rotary valve 131, a rotating shaft 132 and a stirring blade 133, the rotary valve 131 is rotatably connected to the intelligent safety valve 121, one end of the rotating shaft 132 is fixedly connected to the rotary valve 131, the end of the rotating shaft 132 away from the rotary valve 131 passes through the center of the placement plate 14, the stirring blade 133 is movably connected to the end of the rotating shaft 132 away from the rotary valve 131, the stirring blade 133 is arranged around the rotating shaft 132 in a surrounding ascending manner, and the stirring blade 133 is beveled into a blade, which can have both stirring effect and cutting effect, the peripheral wall of the rotary valve 131 is provided with a through hole, and the peripheral wall of the rotary valve 131 is connected with an L-shaped circular tube 134, and the through hole is connected to the L-shaped circular tube 134.

[0046] In this way, the rotary valve 131 is rotatably connected with the intelligent safety valve 121. After the intelligent safety valve 121 is opened, water vapor enters the internal space of the rotary valve 131 under pressure, and then continues to enter the L-shaped circular tube 134 through the through hole, and rushes out from the L-shaped circular tube 134, forming a driving force to drive the rotary valve 131 to rotate, and the rotating shaft 132 on the rotary valve 131 rotates together, so that the stirring blade 133 on the rotating shaft 132 can stir the plants on the placement plate 14, and the stirring blade 133 is cut obliquely into a blade, which can also have a cutting effect, crush the plant body, and increase the surface area of ​​the plant material. Due to the increase in the surface area, the effective ingredients in the plant material can be more fully mixed with water vapor. Gas contact, this wider contact area is conducive to better penetration of water vapor into the interior of the plant material, so as to more effectively carry out the essence therein. Secondly, it can continue to further destroy the plant cell wall, so that the essence in the cell is easier to release. The cell wall is the outer structure of the plant cell, with a certain hardness and toughness. Through stirring and cutting, the integrity of the cell wall can be broken, so that the liquid and solid components in the cell can flow out more easily, thereby improving the extraction efficiency of the essence. Moreover, the stirring blade 133 is detachable. After disassembly, it is convenient to clean on the one hand, and to take out the placement plate 14 on the other hand. Different types of stirring blades 133 can be placed for different plants.

[0047] See also Figure 2 The embodiment of the present application provides a negative ion plant essence extraction device, wherein the outer ring of the placement plate 14 is provided with a groove, and a limiting plate 151 is provided inside the tank body 15, and the placement plate 14 and the tank body 15 are movably connected through the limiting plate 151.

[0048] With such arrangement, the placement plate 14 will not slide down along the inner wall of the tank body 15 in the longitudinal direction, and will not drive the placement plate 14 to rotate together when the rotating shaft 132 rotates in the transverse direction. Otherwise, the placement plate 14 will rotate together with the rotating shaft 132, and the two will remain relatively still. The stirring blade 133 on the rotating shaft 132 and the plant on the placement plate 14 will also remain relatively still, and the purpose of stirring the plant body will not be achieved. The placement plate 14 is detachable, and a placement plate 14 with water vapor holes of different sizes can be selected according to the size of the placed plant.

[0049] See also Figure 1 The embodiment of the present application provides a negative ion plant essence extraction device, the condensation mechanism 2 includes a shell 21, a condensation tube 22, a second water inlet 23 and a second water outlet 24, the condensation tube 22 is arranged in the shell 21, the condensation tube 22 is in an ascending spiral shape, the second water inlet 23 and the second water outlet 24 are both arranged on the shell 21, one end of the condensation tube 22 is movably connected to the conduit 4, and the other end is movably connected to the separator 3.

[0050] In this way, cold water is introduced from the second water inlet 23 until the water can flow out from the second water outlet 24. At this time, the cold water occupies the remaining space between the condenser 22 and the inside of the shell 21, and the condenser 22 is completely immersed in the cold water. The plant essence enters the condenser 22 along with the water vapor through the conduit 4. The water that has reached the boiling point condenses into water droplets when it is cooled and gathers into a water flow. Together with the plant essence, it flows downward along the condenser 22 into the separator 3, and the separator 3 realizes the separation of water and plant essence.

[0051] See also Figure 1 as well as Figure 2 The embodiment of the present application provides a negative ion plant essence extraction device, wherein a pressure gauge 10 is provided on the tank cover 16 .

[0052] With such arrangement, during the distillation process, if the internal pressure of the equipment is too high, it may cause safety problems such as equipment rupture and leakage. The pressure gauge 10 can detect pressure abnormalities in time and remind the operator to take corresponding measures, such as reducing the heating power, opening the vent valve, etc., to ensure the safety of the equipment and the operator.

[0053] See also Figure 2 as well as Figure 3The embodiment of the present application provides a negative ion plant essence extraction device, wherein a first circular ring 5 is provided at one end of the tank body 15 away from the evaporation component 11, and an annular groove is provided in the middle of the first circular ring 5; a second circular ring 6 is provided on the tank cover 16, and an annular groove is also provided in the middle of the second circular ring 6, and a sealing ring 7 is provided between the annular grooves, one side of the sealing ring 7 abuts against the annular groove of the first circular ring 5, and the other side abuts against the annular groove of the second circular ring 6, and a locking device 8 is provided on the second circular ring 6, and a lock core 9 opposite to the locking device 8 is provided on the first circular ring 5.

[0054] With such arrangement, the sealing ring 7 between the annular grooves can ensure a tight connection between the tank body 15 and the tank cover 16, and effectively prevent steam leakage, which is particularly important for systems that need to maintain a high pressure and high temperature environment. Through the close cooperation between the lock 8 and the lock core 9, it can be ensured that the tank cover 16 is stable and not loose in the closed state, preventing leakage to the outside and improving safety. At the same time, under the premise of safety, the design of the lock 8 enables the operator to easily and quickly open or close the tank cover 16.

After the pressure reaches the threshold, it enters the tank body 15 and provides power to the rotary valve 131 at the same time, driving the rotating shaft 132 to rotate, so that the stirring blade 133 stirs the raw materials to increase the contact area between the raw materials and the water vapor;
