Description

Technical Field

[0001] The present invention relates to a preparation method of an oral spray, in particular to a preparation method of an oral spray applied to the field of oral care. Background Art

[0002] Oral sprays contain ingredients for antibacterial, anti-inflammatory or freshening breath, which can temporarily relieve bad breath and provide a short-term sense of freshness. However, the existing oral sprays have limited deodorizing effects, and most of them use the fragrance of ingredients to cover up bad breath, resulting in not only no relief of bad breath but also an aggravation of bad breath.

[0003] To solve the problem of deodorization of oral sprays, a certain oral spray in the market adopts the design of extracting plant ingredients and has a certain market share.

[0004] The specification of Chinese Patent CN101406572B discloses a spray for eliminating bad breath, which is made of the following substances in weight ratio and a pharmaceutically acceptable carrier: 3-5 parts of honeysuckle, 0.5-1.5 parts of mint, 1-6 parts of cloves, 4-8 parts of perilla leaves, 0.1-0.5 parts of borneol, 3-7 parts of osmanthus, 5-11 parts of green tea, and 3-5 parts of liquorice. This spray has a very obvious effect of eliminating bad breath and is suitable for large-scale promotion.

[0005] The specification of Chinese Patent CN105232781A discloses a spray for removing bad breath and its preparation method. The spray is prepared by mixing green tea extract, jasmine extract, and honeysuckle extract with other drugs. Research shows that the above-mentioned traditional Chinese medicine extracts have bactericidal and antibacterial effects, and the aromatic oils contained therein can remove bad breath and freshen breath. Long-term use is beneficial to regulating the oral environment and has a therapeutic and improving effect on oral inflammation.

[0006] Although the existing deodorizing oral sprays have deodorizing effects, obtaining the relevant extracts is relatively cumbersome, difficult to prepare, and costly. In addition, it is easy to have incomplete filtration during the preparation process, resulting in the spray containing residual impurities, which in turn causes discomfort in the oral cavity when using the product. Summary of the Invention

[0007] Aiming at the above-mentioned prior art, the technical problem to be solved by the present invention is how to simplify the preparation process of deodorizing oral cavity and effectively improve the filtration and purification effect, so as to improve the comfort of using the oral spray.

[0008] To solve the above problems, the present invention provides a preparation method of an oral spray, which comprises raw materials composed of the following parts by weight: 100 parts of purified water, 28 - 32 parts of citric acid, 1 - 3 parts of sodium cyclamate, 0.5 - 0.8 parts of sodium benzoate, 1 - 2 parts of potassium sorbate, 2 - 3 parts of disodium 5'-ribonucleotide, 5 - 6 parts of glacial acetic acid, 30 - 35 parts of honey, 7.8 - 8 parts of edible ethanol, 2 - 3 parts of edible baking soda, and 2 - 3 parts of essence; The preparation method of the oral spray comprises the following steps: S1. First, prepare a stirring tank, pour purified water into the stirring tank first, and then heat the stirring tank to 50 - 70 °C; S2. Then, sequentially add citric acid, sodium cyclamate, sodium benzoate, potassium sorbate, disodium 5'-ribonucleotide, and essence into the stirring tank, and continuously stir during the feeding process; S3. Stop stirring after the raw materials are all dissolved, then cool down the obtained mixed liquid, and after the mixed liquid is cooled to room temperature, pass it into a filter to purify; S4. Add glacial acetic acid, honey, edible ethanol, and edible baking soda to the purified mixed liquid, and slowly stir for 1 - 2 minutes to obtain the oral spray; The filter includes a filter tower. The upper end of the filter tower is connected with a plurality of symmetrically distributed liquid inlet pipes with electromagnetic valves, and the lower end of the filter tower is connected with a liquid outlet pipe. The inner wall of the filter tower is fixedly connected with a plurality of installation rings distributed at equal intervals up and down. The inner side of the installation ring is rotatably connected with a rotating ring, and the inner side of the rotating ring is fixedly connected with a filter screen.

[0009] In the above preparation method of the oral spray, the oral spray is prepared by using easily obtainable raw materials and a simple process, effectively reducing the production cost, and performing efficient purification and filtration during the preparation process, thereby effectively improving the use comfort of the product.

[0010] As a further improvement of the present application, a driving cavity is formed on the inner wall of the installation ring, and a toothed ring penetrating into the interior of the driving cavity is fixedly connected to the side wall of the rotating ring far away from the filter screen. A plurality of driving motors are installed in the driving cavity and are distributed in an equidistant and circumferential manner. The output end of the driving motor is connected with a gear meshing with the toothed ring. Under normal filtration conditions, a plurality of filter screens perform multi-stage filtration on the oral spray to achieve efficient purification. As the filtration progresses, more and more impurities accumulate on the filter screen. Every fixed period of time, the electromagnetic valve on the liquid inlet pipe is closed to stop the liquid supply, and then the driving motor is started to make the gear drive the toothed ring to rotate, so that the filter screen can be driven to rotate. The impurities accumulated on the filter screen move outward under the action of centrifugal force, thus realizing self-cleaning of the filter screen.

[0011] As a further improvement of the present application, the rotating ring includes a fixed section fixedly connected to the mounting ring and an elastic moving section fixedly connected to the filter screen. A deformation section is fixedly connected between the fixed section and the elastic moving section. A plurality of electromagnets are installed on the inner wall of the fixed section and are evenly distributed in a circumferential manner. The magnetic force generated by the electromagnets generates a suction force on the elastic moving section. Before starting the self-cleaning of the filter screen, the electromagnets are first started. The magnetic force generated by the electromagnets generates a suction force on the elastic moving section, and the elastic moving section moves towards the fixed section. At this time, the filter screen is flattened, so that the impurities on the filter screen can move more smoothly to the outside under the centrifugal force, thereby effectively improving the self-cleaning effect of the filter screen.

[0012] As a supplement to the further improvement of the present application, the width of the deformation section is greater than the width of the fixed section. The fixed section is made of a hard material, and the deformation section is made of an elastic material. In order to make the filter screen be flattened as much as possible, the width of the deformation section is greater than the width of the fixed section, so as to leave more moving space for the deformation section.

[0013] As a further improvement of the present application, the filter screen includes an upper filter layer and a lower shaping keel. The filter layer is made of polypropylene material, and the shaping keel is made of polyurethane elastic material. The filter layer plays a role in filtering the oral spray, while the shaping keel plays a role in maintaining the shape of the filter screen. After the electromagnet is turned off, the shaping keel relies on its own elasticity to make the filter layer return to its original shape for continuous filtering.

[0014] As another improvement of the present application, brackets are fixedly connected to the upper and lower sides of each filter screen. An installation seat is fixedly connected to the position of the bracket facing the center point of the filter screen. A spotlight is installed at the lower end of the installation seat, and a light intensity detector is installed at the upper end of the installation seat. A rotating protection cylinder is rotatably connected to the upper end of the installation seat outside the light intensity detector, and a glass plate is fixedly inlaid at the upper end of the rotating protection cylinder. A driving mechanism connected to the rotating protection cylinder is installed at the upper end of the installation seat. A light intensity comparison and analysis module is also electrically connected to the light intensity detector, and a raw material adjustment suggestion module is electrically connected to the light intensity comparison and analysis module. Before starting the self-cleaning of the filter screen, the spotlight is first started. The spotlight emits light downward to the filter screen below. The light passes through the filter screen and is received by the light intensity detector. The light intensity detector detects the light intensity. The more impurities accumulated on the filter screen, the weaker the light intensity detected by the light intensity detector, and vice versa. In this way, before each self-cleaning at regular intervals, the light intensity detector will first detect the light intensity of the filter screen, and then the light intensity comparison and analysis module will compare and analyze the data detected multiple times to detect the increase or decrease of impurities in the oral spray. The raw material adjustment suggestion module will display the result of the comparison and analysis in the form of a graph, so that the staff can adjust the process parameters in time according to the data, thereby effectively reducing the amount of impurities in the raw materials and effectively improving the quality of the product.

[0015] As yet another improvement of the present application, a plurality of cleaning windows are further installed on the side wall of the filter tower, and each cleaning window corresponds to an installation ring. When the filter screen performs self-cleaning, the impurities on the filter screen move outward under the action of centrifugal force and accumulate near the installation ring. At this time, opening the cleaning window can clean out the impurities, so as to prevent excessive accumulation of impurities from affecting the self-cleaning of the filter screen.

[0016] In summary, by using easily obtainable raw materials and an easily operable process to prepare the oral spray, the cost can be saved while effectively improving the production efficiency. In addition, a filter is added during the preparation process to perform multi-stage filtration on the oral spray to remove impurities, effectively improving the product quality. Moreover, the self-cleaning of the filter screen is realized by the action of centrifugal force, enabling the filter screen to maintain an efficient filtration effect. Before each self-cleaning of the filter screen, a light intensity detector is used to detect the light transmittance of the filter screen to detect the accumulation of impurities on the filter screen, thereby indirectly knowing the situation of impurities carried in the oral spray and giving suggestions for adjusting the process parameters, thus effectively improving the product quality.

Detailed Embodiments

[0019] The following will make a detailed description of two implementation manners of the present application in conjunction with the accompanying drawings.

[0020] The first implementation manner: It includes raw materials composed of the following parts by weight: 100 parts of pure water, 28 - 32 parts of citric acid, 1 - 3 parts of sodium cyclamate, 0.5 - 0.8 parts of sodium benzoate, 1 - 2 parts of potassium sorbate, 2 - 3 parts of disodium 5'-ribonucleotide, 5 - 6 parts of glacial acetic acid, 30 - 35 parts of honey, 7.8 - 8 parts of edible ethanol, 2 - 3 parts of edible sodium bicarbonate, and 2 - 3 parts of essence; Figure 1 It is shown that the preparation method of the oral spray includes the following steps: S1. First, prepare a stirring tank, pour pure water into the stirring tank first, and then heat the stirring tank to 50 - 70 °C; S2. Then, sequentially add citric acid, sodium cyclamate, sodium benzoate, potassium sorbate, disodium 5'-ribonucleotide, and essence into the stirring tank, and continuously stir during the feeding process; S3. Stop stirring after all the raw materials are dissolved, then cool down the obtained mixed liquid, and after the mixed liquid is cooled to room temperature, pass it into a filter to purify; S4. Add glacial acetic acid, honey, edible ethanol, and edible sodium bicarbonate to the purified mixed liquid, and slowly stir for 1 - 2 minutes to obtain the oral spray; Figure 2 、 3 、4、5 and Figure 6It is shown that the filter includes a filter tower 1. A plurality of symmetrically distributed liquid inlet pipes 2 with solenoid valves are connected to the upper end of the filter tower 1, and a liquid outlet pipe 3 is connected to the lower end of the filter tower 1. A plurality of mounting rings 4 are fixedly connected to the inner wall of the filter tower 1 at equal intervals up and down. A plurality of cleaning windows 16 are also installed on the side wall of the filter tower 1, and each cleaning window 16 corresponds to a mounting ring 4. When the filter screen 6 performs self-cleaning, the impurities on the filter screen 6 move outward under the action of centrifugal force and accumulate near the mounting ring 4. At this time, opening the cleaning window 16 can clean out the impurities, so as to prevent excessive accumulation of impurities from affecting the self-cleaning of the filter screen 6. A driving cavity 401 is formed in the inner wall of the mounting ring 4, and a toothed ring 7 penetrating into the interior of the driving cavity 401 is fixedly connected to the side wall of the rotating ring 5 away from the filter screen 6. A plurality of driving motors 8 (the specific model is selected according to actual needs and will not be described in detail here) are installed in the driving cavity 401 at equal intervals around, and the output end of the driving motor 8 is connected with a gear 9 meshing with the toothed ring 7. Under normal filtration conditions, a plurality of filter screens 6 perform multi-stage filtration on the oral spray, so as to achieve efficient purification. As the filtration progresses, more and more impurities accumulate on the filter screen 6. Every fixed period of time, the solenoid valve on the liquid inlet pipe 2 is closed to stop the liquid supply, and then the driving motor 8 is started to make the gear 9 drive the toothed ring 7 to rotate, so that the filter screen 6 can follow and rotate. The impurities accumulated on the filter screen 6 move outward under the action of centrifugal force, thus realizing the self-cleaning of the filter screen 6; Figure 4 , 6 and Figure 7 It is shown that a rotating ring 5 is rotatably connected to the inner side of the mounting ring 4. The rotating ring 5 includes a fixed section 501 fixedly connected to the mounting ring 4, an elastic moving section 503 fixedly connected to the filter screen 6, and a deformation section 502 fixedly connected between the fixed section 501 and the elastic moving section 503. A plurality of electromagnets 10 (the specific model is selected according to actual needs and will not be described in detail here) are installed on the inner wall of the fixed section 501 at equal intervals around, and the magnetic force generated by the electromagnets 10 generates a suction force on the elastic moving section 503. Before starting the self-cleaning of the filter screen 6, the electromagnets 10 are first started. The magnetic force generated by the electromagnets 10 generates a suction force on the elastic moving section 503, and the elastic moving section 503 moves towards the fixed section 501. At this time, the filter screen 6 is flattened, so that the impurities on the filter screen 6 can move more smoothly to the outside under the action of centrifugal force, thus effectively improving the self-cleaning effect of the filter screen 6. The width of the deformation section 502 is greater than the width of the fixed section 501. The fixed section 501 is made of a hard material (preferably a high-strength wear-resistant plastic material, and other materials can also be selected according to actual needs), and the deformation section 502 is made of an elastic material (preferably a rubber material, and other materials can also be selected according to actual needs). In order to make the filter screen 6 be flattened as much as possible, the width of the deformation section 502 is greater than the width of the fixed section 501, so as to leave more moving space for the deformation section 502; Figure 5 As shown, a filter screen 6 is fixedly connected to the inner side of the rotating ring 5. The filter screen 6 includes an upper filter layer and a lower shaping keel. The filter layer is made of polypropylene material, and the shaping keel is made of polyurethane elastic material. The filter layer functions to filter the oral spray, while the shaping keel functions to maintain the shape of the filter screen 6. After the electromagnet 10 is turned off, the shaping keel relies on its own elastic force to restore the filter layer to its original shape, facilitating continuous filtration.

[0021] The second implementation mode: Figure 3 , 8 As shown, brackets 11 are fixedly connected above and below each filter screen 6, and a mounting seat 12 is fixedly connected at the position of the brackets 11 facing the center point of the filter screen 6. A spotlight 13 (the specific model is selected according to actual needs and will not be described in detail here) is installed at the lower end of the mounting seat 12, and a light intensity detector 15 (the specific model is selected according to actual needs and will not be described in detail here) is installed at the upper end of the mounting seat 12. A rotating protective cylinder 14 is rotatably connected to the upper end of the mounting seat 12 outside the light intensity detector 15, and a glass plate 1401 is fixedly inlaid at the upper end of the rotating protective cylinder 14. A driving mechanism connected to the rotating protective cylinder 14 is installed at the upper end of the mounting seat 12. A light intensity comparison and analysis module is also electrically connected to the light intensity detector 15, and a raw material adjustment suggestion module is electrically connected to the light intensity comparison and analysis module (the specific electrical connection structure and working principle of this part are well-known technologies for those skilled in the relevant field and will not be described in detail here). Before starting the self-cleaning of the filter screen 6, first start the spotlight 13. The spotlight 13 emits light downward to the filter screen 6 below. The light passes through the filter screen 6 and is received by the light intensity detector 15. The light intensity detector 15 detects the light intensity. The more impurities accumulated on the filter screen 6, the weaker the light intensity detected by the light intensity detector 15, and vice versa. In this way, before self-cleaning at regular intervals, the light intensity detector 15 will first detect the light intensity of the filter screen 6, and then the light intensity comparison and analysis module will compare and analyze the data detected multiple times to detect the increase or decrease of impurities in the oral spray. The raw material adjustment suggestion module will display the result of the comparison and analysis in the form of a graph, so that the staff can adjust the process parameters in a timely manner according to the data, thereby effectively reducing the amount of impurities in the raw materials and effectively improving the quality of the product.

[0022] Combined with the current actual needs, the above implementation modes adopted in this application do not limit the protection scope thereto. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
