Description

Technical Field

[0001] This invention belongs to the field of hair darkening cream production technology, specifically a hair darkening cream preparation device. Background Technology

[0002] Hair-darkening ointment is a medicinal diet made from a variety of traditional Chinese medicine ingredients. It is taken orally daily to nourish gray hair, and the formula is believed to nourish yin and tonify the kidneys, making hair black and shiny. However, in the current technology for preparing hair-darkening ointment, the liquid gradually thickens as the water in the decoction evaporates. During this thickening process, the consistency needs to be manually judged, and a precise amount of sugar needs to be added. The uncertainty of this human judgment affects the timing and amount of sugar added. Furthermore, the stirring effect of the existing agitator blades on the hair-darkening ointment continuously decreases; the further the liquid is from the agitator blades, the worse the rotation becomes, sometimes even stopping completely. This can lead to scorching of the liquid at the bottom, causing the hair-darkening ointment to fail and resulting in resource waste. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention increases the tilt angle of the stirring blades by reducing their rotational resistance, thereby enhancing the impact force of the stirring blades on the liquid when it becomes viscous, improving the mixing uniformity of the liquid in the heating tank, and preventing the liquid from being scorched due to excessive viscosity.

[0016] 2. This invention detects different amounts of medicinal liquid by detecting the blade fan, thereby determining the total amount of sugar to be added. This ensures that the amount of sugar corresponds to different amounts of medicinal liquid, improving the integrity of the process. By cooperating with the inclined sliding groove on the limiting block and the second limiting rod, the sugar addition time is adjusted, so that sugar is added at the same viscosity for different amounts of medicinal liquid. Both the total amount of medicinal liquid and the viscosity of the medicinal liquid are factors affecting the rotation resistance of the spline cylinder. That is, under the condition that the total amount of medicinal liquid is equal, the only factor affecting the rotation resistance of the spline cylinder is the viscosity of the medicinal liquid (the more total amount of medicinal liquid in the heating tank, the larger the deflection angle of the limiting plate, and the larger the distance between the hole on the limiting plate and the elastic telescopic rod), thus eliminating the influence of different amounts of medicinal liquid on the rotation resistance of the spline cylinder.

[0017] 3. The present invention uses a fixed rod to drive the sliding shell to move up and down repeatedly. The sliding shell continuously turns the medicinal liquid in the heating tank vertically. After the sliding shell moves the medicinal liquid upward to the liquid surface, the medicinal liquid in the sliding shell flows downward through the evenly distributed through holes on the sliding shell and forms an evenly distributed strip-shaped path, thereby further dissipating the water in the medicinal liquid into the air, thus improving the preparation efficiency of hair darkening ointment.

The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise. The term "by way of example" used herein means "used as an example, embodiment, or illustration." Any embodiment illustrated herein as "by way of example" is not necessarily to be construed as superior to or better than other embodiments. Furthermore, for the purpose of better illustrating this application, those skilled in the art will understand that numerous specific details are set forth in the various embodiments described below. This application can be practiced without certain specific details. In some embodiments, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the spirit of this application.

[0030] Example 1: A hair-darkening cream preparation apparatus, please refer to [link / reference]. Figures 1-3 The device includes a frame 1, to which a heating tank 2 is fixedly connected. The heating tank 2 contains a heating device (existing technology) used to heat the medicinal liquid inside the heating tank 2. A fixed shell 3 is fixedly connected to the upper side of the heating tank 2. The fixed shell 3 is fixedly connected to two mirror-distributed feed pipes 4, which are used to transport different medicinal liquids. The lower ends of both feed pipes 4 are connected to the heating tank 2. A motor 5 is fixedly connected to the upper side of the fixed shell 3 via a mounting bracket. The output shaft of the motor 5 is fixedly connected to a rotating shaft 6 rotatably connected to the fixed shell 3. A sleeve 7 is rotatably connected to the middle of the fixed shell 3. The rotating shaft 6 is driven by the sleeve 7 via a spur gear set. A splined cylinder 8 is rotatably connected to the lower interior of the fixed shell 3. The splined cylinder 8 has a cylindrical cavity inside. A torsion spring is installed between the upper outer side of the splined cylinder 8 and the sleeve 7. The splined cylinder 8 is rotatably connected to... The stirring blades 9 are evenly spaced and arranged in a circumferential array. The stirring blades 9 are used to rotate and mix the medicinal liquid in the heating tank 2. As the medicinal liquid in the heating tank 2 becomes more viscous, the deflection angle of the stirring blades 9 with respect to the vertical direction becomes smaller and smaller, thereby expanding the range of the stirring of the medicinal liquid in the heating tank 2. A discharge pipe is provided on the lower side of the frame 1 for discharging the prepared hair-darkening ointment. A suction pipe is provided on the left side of the frame 1. The suction pipe is connected to an external vacuum pump to provide a negative pressure environment for the heating tank 2. The splined cylinder 8 is provided with an adjustment mechanism 12 for adjusting the deflection angle of the evenly spaced and circumferentially arranged stirring blades 9. The shape of the stirring blades 9 is inclined from both ends to the middle. When the stirring blades 9 rotate, the two ends of the stirring blades 9 drive the medicinal liquid to converge towards the middle and mix it, thereby improving the degree of mixing of the medicinal liquid in the heating tank 2.

[0031] Please see Figure 3 and Figure 4A first fixing block 10 is fixedly connected to the outer side of the upper part of the splined cylinder 8, and a second fixing block 11 is fixedly connected to the inner side of the sleeve 7. The first fixing block 10 and the second fixing block 11 are in a limiting fit to ensure the torsion spring between the splined cylinder 8 and the sleeve 7 is in a stored state. The torsion spring between the splined cylinder 8 and the sleeve 7 is initially in a stored state, and the torsional force of the torsion spring between the splined cylinder 8 and the sleeve 7 is equal to the rotational resistance of the splined cylinder 8 and its parts.

[0032] Please see Figure 3 and Figure 4 The adjusting mechanism 12 includes a first fixed ring 1201, which is fixedly connected to the cylindrical cavity of the splined cylinder 8. The splined cylinder 8 is slidably connected to a first sliding rod 1202 arranged in a circumferential array. The first sliding rod 1202 has racks evenly spaced vertically. The stirring blade 9 has gears that mesh with adjacent racks on adjacent first sliding rods 1202. The gears on the stirring blade 9 are located inside the splined cylinder 8. When the first sliding rod 1202 moves downward, it drives the adjacent stirring blade 9 to rotate via its racks. A first sliding ring 1203 is fixedly connected to the upper side of the circumferentially arrayed first sliding rods 1202, and the first sliding ring 1203 is located above the first fixed ring 1201. Furthermore, springs are circumferentially distributed between the two. A first limiting rod 1204 is fixedly connected to the upper side of the first sliding ring 1203. A limiting cylinder 1205 is rotatably connected to the upper side of the spline cylinder 8. A spiral inclined surface is provided on the lower side of the limiting cylinder 1205. The limiting cylinder 1205 is fixedly connected to the sleeve 7 through the mounting rod. The spiral inclined surface of the limiting cylinder 1205 cooperates with the first limiting rod 1204. When the limiting cylinder 1205 rotates counterclockwise, the spiral inclined surface on the lower side of the limiting cylinder 1205 squeezes and drives the first limiting rod 1204 to move downward. The distance between the first fixed ring 1201 and the first sliding ring 1203 is greater than the length of the spiral inclined surface on the limiting cylinder 1205 in the vertical direction, thereby ensuring the rotation range of the stirring blade 9.

[0033] When preparing hair-darkening ointment using this invention, first prepare the raw materials for the hair-darkening ointment (10-40 parts of Polygonum multiflorum, 20-50 parts of mulberry, 5-15 parts of Rehmannia glutinosa, 15-35 parts of Rubia cordifolia, 20-45 parts of Eucommia ulmoides male flowers, 60-80 parts of sesame, 15-19 parts of black bark root, and 32-36 parts of Gentiana scabra). The efficacy of hair-darkening ointment prepared with different proportions of raw materials will also be different. Adjust the proportion of Rehmannia glutinosa and Rubia cordifolia according to the desired efficacy of the hair-darkening ointment. After the proportion is adjusted, add sufficient water to Rehmannia glutinosa and Rubia cordifolia separately and decoct them. After the decoction is completed, separate the medicinal liquid from the dregs, and the ointment preparation is completed.

[0034] The raw Rehmannia glutinosa liquid and the madder liquid are added to the heating tank 2 through the left and right feed pipes 4 respectively. Then, the two feed pipes 4 are closed, and the heating device of the heating tank 2 is controlled to heat the mixed liquid inside. At the same time, the external vacuum pump is controlled to extract the gas inside the heating tank 2 through the pipe on the upper side of the heating tank 2, so that the heating tank 2 forms a negative pressure environment, thereby lowering the boiling point of water in the mixed liquid and accelerating the evaporation of water in the mixed liquid. The motor 5 is started, and the output shaft of the motor 5 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the sleeve 7 to rotate through the spur gear set. The sleeve 7 drives the splined cylinder 8 to rotate through the torsion spring between it and the splined cylinder 8. The splined cylinder 8 drives the equidistant and circumferentially arrayed stirring blades 9 on it to rotate and mix the mixed liquid in the heating tank 2. As the heating tank 2 continues to heat the mixed liquid inside, the water in the mixed liquid in the heating tank 2 gradually evaporates, and the mixed liquid becomes more and more viscous.

[0035] When the viscosity of the mixed medicinal liquid reaches a level where sugar can be added, a certain amount of sugar is added to the heating tank 2. The heating tank 2 continues to heat the medicinal liquid inside. During the heating and evaporation process, the stirring blade 9 rotates continuously and drives the medicinal liquid to rotate, preventing the medicinal liquid from sticking to the bottom and being scorched. When the viscosity of the medicinal liquid reaches the standard of hair darkening ointment, the motor 5 is turned off, and the prepared hair darkening ointment is discharged through the discharge pipe on its lower side.

[0036] During the stirring process of the above-mentioned stirring blade 9, as the liquid becomes more viscous, the rotational resistance of the stirring blade 9 increases, and the rotational resistance of the splined cylinder 8 also increases. When the rotational resistance exceeds the torsional force of the torsion spring between the splined cylinder 8 and the sleeve 7, the splined cylinder 8 and the sleeve 7 gradually rotate relative to each other as the liquid becomes more viscous. The splined cylinder 8 drives the first sliding rods 1202, which are arranged in a circumferential array, to rotate through the first fixed ring 1201. The first sliding rods 1202 drive the first limiting rod 1204 to rotate through the first sliding ring 1203. During the rotation of the first limiting rod 1204, it is gradually moved downward by the limiting surface of the lower side of the limiting cylinder 1205. The first limiting rod 1204 drives the first sliding rods 1202, which are arranged in a circumferential array, to move downward through the first sliding ring 1203. Taking one of the first sliding rods 1202 as an example, the first sliding rod 1202 drives the equally spaced racks on it to move downwards. The first sliding rod 1202 drives the equally spaced racks on it to mesh with the gears on the adjacent stirring blades 9 and drive the stirring blades 9 to rotate. The stirring blades 9 increase their tilt angle according to their rotational resistance, thereby increasing the impact force of the stirring blades on the medicine when the medicine becomes viscous. This improves the mixing degree of the medicine in the heating tank and prevents the medicine from being scorched due to excessive viscosity. During this process, the deflection angle of the stirring blades 9 in the vertical direction gradually decreases until the hair-darkening ointment is prepared and discharged through the discharge pipe on the lower side of the frame 1. Then the motor 5 is turned off and the two conveying pipes 4 are turned on at the same time to start a new round of preparation until all raw materials are consumed.

[0037] Example 2: Based on Example 1, please refer to... Figure 2 , Figure 5 and Figure 6It also includes a control mechanism 13 for controlling the total amount of sugar and the time of addition. The control mechanism 13 is located in the fixed shell 3 and includes fixed tubes 1301 arranged in a left-right mirror image. The mirror-arranged fixed tubes 1301 are all fixed to the upper side of the fixed shell 3. A temporary storage shell 1302 is fixed to the inner side of the fixed shell 3 for temporarily storing sugar. The temporary storage shell 1302 is composed of a rectangular shell and a frustum-shaped shell. The upper area of ​​the frustum-shaped shell is larger than the lower area to prevent sugar from remaining in the temporary storage shell 1302. The mirror-arranged fixed tubes 1301 are all connected to the temporary storage shell 1302. Since the amount of sugar corresponding to equal parts of different medicine solutions is different, the two fixed tubes 1301 are used to provide an equal amount of sugar to the amount of medicine solution introduced into the adjacent delivery pipe 4. The delivery pipe 4 is connected to a detection shell 1303 located inside the fixed shell 3. The detection shell 1303 contains... A detection fan 1304 is rotatably connected. Each blade of the detection fan 1304 can completely block the inside of the conveying pipe 4. A gearbox 1305 with left and right mirror distribution is fixedly connected inside the fixed shell 3. The upper side of the gearbox 1305 is provided with a mirror distribution of output shafts. The output shaft near the sleeve 7 is fixedly connected with a threaded rod and is a unidirectional output rotation. The output shaft away from the sleeve 7 is fixedly connected with a straight rod and is a bidirectional output transmission. The fixed pipe 1301 is slidably connected with a first baffle plate 13061 and a tension spring is provided between the two. The first baffle plate 13061 is used to control the amount of sugar added to the temporary storage shell 1302. A first fixed frame 1307 is fixedly connected to the rear side of the first baffle plate 13061. The first fixed frame 1307 is provided with a rack. The straight rod on the output shaft of the gearbox 1305 away from the sleeve 7 is fixedly connected with a gear that meshes with the rack on the adjacent first fixed frame 1307.

[0038] Please see Figure 7 and Figure 8A limiting plate 13062 is rotatably connected to the upper side inside the sleeve 7. A first telescopic rod 1308 is fixedly connected to the upper side of the limiting plate 13062. The amount of liquid medicine passing through the right-side conveying pipe 4 is determined by the extension of the first telescopic rod 1308's telescopic end. A second fixing ring 1309 is fixedly connected to the telescopic end of the first telescopic rod 1308. A fixing plate 1310 is rotatably connected to the upper side of the second fixing ring 1309 via an mounting ring. The fixing plate 1310 is connected to the screw on the one-way output shaft on the upper side of the right-side gearbox 1305. The upper side of the limiting plate 13062 is fixedly connected to the threaded rod via a mounting bracket, and the extension amount of the extension end of the second telescopic rod 1311 determines the total amount of liquid medicine passing through the left conveying pipe 4. The extension end of the second telescopic rod 1311 is fixedly connected to the third fixing ring 1312, and the lower side of the third fixing ring 1312 is rotatably connected to the second fixing bracket 1313 via a mounting ring.

A third telescopic rod 1314 is fixedly connected to the upper side of cylinder 7 via a mounting bracket. The amount of extension of the third telescopic rod 1314 determines the total amount of liquid in heating tank 2. The telescopic rods of the first telescopic rod 1308, the second telescopic rod 1311, and the third telescopic rod 1314 are all sealed to their own fixing parts. Hydraulic oil is filled into the first telescopic rod 1308, the second telescopic rod 1311, and the third telescopic rod 1314. The first telescopic rod 1308 and the second telescopic rod 1311 are connected to the third telescopic rod 2 via pipes. The three telescopic rods 1314 are connected, and the connecting pipes are all elastic telescopic pipes. The telescopic end of the third telescopic rod 1314 is fixedly connected to a limiting block 1315. The upper side of the limiting plate 13062 is fixedly connected to a second limiting rod 1316. The second limiting rod 1316 is provided with an inclined sliding groove, and the inclined sliding groove on the second limiting rod 1316 cooperates with the limiting block 1315. When the limiting block 1315 moves downward, the limiting block 1315 squeezes the inclined sliding groove on the second limiting rod 1316 and drives the second limiting rod 1316 to rotate.

[0039] Please see Figures 7-9The upper side of the limiting plate 13062 is slidably connected to a second sliding ring 1317 via evenly distributed mounting rods. The upper end of the first limiting rod 1204 is fixedly connected to a fourth telescopic rod 1318, which is slidably connected to the limiting cylinder 1205.

The upper side of the limiting plate 13062... A through hole is provided, and the telescopic end of the elastic telescopic rod 1319 cooperates with the limiting plate 13062. When the elastic telescopic rod 1319 rotates to below the through hole on the limiting plate 13062, the telescopic end of the elastic telescopic rod 1319 pops out and embeds into the through hole of the limiting plate 13062. A second sliding rod 1320 is slidably connected to the through hole on the limiting plate 13062. The second sliding rod 1320 is fixed to the second sliding ring 1317 through a mounting plate. The lower end of the second sliding rod 1320 is connected to the elastic telescopic rod 13062. When the telescopic end of the elastic telescopic rod 1319 is inserted into the through hole of the limiting plate 13062, the telescopic end of the elastic telescopic rod 1319 drives the second sliding rod 1320 to move upward.

The fixed shell 3 is fixedly connected to the feed pipe 1322 for adding sugar into the heating tank. The lower side of the frustum-shaped shell part of the temporary storage shell 1302 is connected to the feed pipe 1322. The upper side of the heating tank 2 is connected to the feed pipe 1322. The feed pipe 1322 is rotatably connected to the second baffle plate 1323. The second baffle plate 1323 is used to control the flow area of ​​the feed pipe 1322. A gear is provided on the second baffle plate 1323. The gear on the second baffle plate 1323 is located on the outside of the feed pipe 1322. A rack is provided on the side of the sliding frame 1321 near the feed pipe 1322. The rack on the sliding frame 1321 meshes with the gear on the second baffle plate 1323.

[0040] When the liquid medicine enters the heating tank 2 through the feed pipe 4, it simultaneously supplies sufficient sugar to both fixed pipes 1301. Taking one of the feed pipes 4 as an example, when the liquid medicine passes through the feed pipe 4, it drives the detection vane 1304 to rotate. The detection vane 1304 drives the input shaft of the gearbox 1305 to rotate. The output shaft of the gearbox 1305, which is fixed with a straight rod, drives the gear on it to rotate. The output shaft of the gearbox 1305 meshes with the rack on the first fixed frame 1307 through the straight rod and its upper gear, and drives the first fixed frame 1307 to move backward. The first fixed frame 1307 drives the first baffle plate 13061 to move backward, and at the same time stretches the first baffle plate 13061 and the fixed pipe 1301. As the first baffle plate 13061 gradually moves backward, the sugar flows downward through the gap between the first baffle plate 13061 and the fixed tube 1301 into the temporary storage shell 1302. During the process of injecting the medicine into the heating tank 2, sugar continuously accumulates in the temporary storage shell 1302. When the medicine is completely injected, the tension spring between the first baffle plate 13061 and the fixed tube 1301 drives the first baffle plate 13061 to move forward and reset. At this time, the sugar metering is completed. By detecting the different amounts of medicine through the detection blade 1304, the total amount of sugar added is determined, ensuring that the amount of sugar corresponds to different amounts of medicine, thus improving the integrity of the process of this invention.

[0041] When the liquid medicine drives the detection blade 1304 to rotate, the output shaft of the gearbox 1305 near the sleeve 7 drives the threaded rod to rotate. The rotation of the right threaded rod drives the fixing plate 1310 downward through the thread. The fixing plate 1310 drives the mounting ring to drive the second fixing ring 1309 downward. The second fixing ring 1309 drives the telescopic end of the first telescopic rod 1308 downward and squeezes the hydraulic oil in the first telescopic rod 1308 into the third telescopic rod 1314 through the pipe. Similarly, the output shaft of the left gearbox 1305 near the sleeve 7 drives the second fixing frame 1313 upward through the thread of its threaded rod. The second fixing frame 1313 drives the third fixing ring 1312 upward through the mounting ring. The third fixing ring 1312 drives the telescopic end of the second telescopic rod 1311 upward and squeezes the hydraulic oil in the second telescopic rod 1311 into the third telescopic rod 1314 through the pipe. The hydraulic oil drives the third telescopic rod 1314. The telescopic end moves downward, and the telescopic end of the third telescopic rod 1314 drives the limiting block 1315 to move downward. The limiting block 1315 is squeezed by the inclined groove of the second limiting rod 1316 and drives the second limiting rod 1316 to rotate. The second limiting rod 1316 drives the limiting plate 13062 to rotate, so that the distance between the hole on the limiting plate 13062 and the elastic telescopic rod 1319 gradually increases. Through the cooperation of the limiting block 1315 and the inclined groove on the second limiting rod 1316, the sugar addition time is adjusted. The total amount of medicine and the viscosity of medicine are both factors affecting the rotation resistance of the spline cylinder 8. That is, under the condition that the total amount of medicine is equal, the only factor affecting the rotation resistance of the spline cylinder 8 is the viscosity of medicine (that is, the larger the total amount of medicine in the heating tank 2, the larger the deflection angle of the limiting plate 13062, and the larger the distance between the hole on the limiting plate 13062 and the elastic telescopic rod 1319), thereby eliminating the influence of different total amounts of medicine on the rotation resistance of the spline cylinder 8.

[0042] As the heating tank 2 continuously heats the medicinal liquid inside, the liquid becomes increasingly viscous. The first limiting rod 1204 continuously drives the elastic telescopic rod 1319 to rotate via the fourth telescopic rod 1318 until the telescopic end of the elastic telescopic rod 1319 rotates to the through hole of the limiting plate 13062. The telescopic end of the elastic telescopic rod 1319 pops upward (indicating that the viscosity of the medicinal liquid in the heating tank 2 has reached a level suitable for adding sugar). The telescopic end of the elastic telescopic rod 1319 squeezes and drives the second sliding rod 1320 to move upward. The second sliding rod 1320 drives the second sliding ring 1317 to move upward via the mounting plate. The moving ring 1317 drives the sliding frame 1321 to move upward through the mounting ring. The sliding frame 1321 drives the rack on it to move upward. The rack on the sliding frame 1321 meshes with the gear on the second baffle plate 1323 and drives the second baffle plate 1323 to rotate 90°. At this time, the sugar in the temporary storage shell 1302 flows downward through the feed pipe 1322 into the heating tank 2 and mixes into the medicine liquid. After the sugar is mixed into the medicine liquid, the water in the medicine liquid continues to evaporate until the hair-darkening paste is prepared. It is then discharged through the discharge pipe on the lower side of the frame 1. Then the elastic telescopic rod 1319 and other parts are reset, and a new round of preparation can be carried out until all raw materials are consumed.

[0043] Example 3: Based on Example 2, please refer to... Figure 2 and Figure 10 It also includes a defoaming and filtering mechanism 14 to accelerate the removal of bubbles. The defoaming and filtering mechanism 14 is mounted on the fixed shell 3 and includes an electric push rod 1401, which is fixedly connected to the fixed shell 3. The telescopic end of the electric push rod 1401 is slidably connected to the fixed shell 3. A fixed rod 1402 is fixedly connected to the telescopic end of the electric push rod 1401 and is located inside the heating tank 2. A sliding shell 1403 is splinedly connected to the splined cylinder 8 to intercept bubbles in the liquid. Impurities are removed. The lower end of the sliding shell 1403 is fixedly connected to the fixed rod 1402. The sliding shell 1403 is provided with uniform and circumferentially arrayed through holes for dispersing the medicinal liquid to accelerate the evaporation rate of water in the medicinal liquid. The sliding shell 1403 is provided with fan-shaped through holes that can be passed through the stirring blade 9 and are circumferentially arrayed. A cleaning ring 1404 is splined inside the heating tank 2 for scraping off the viscous medicinal liquid adhering to the inner wall of the heating tank 2. The cleaning ring 1404 is rotatably connected to the sliding shell 1403.

[0044] After sugar is added to heating tank 2, the medicinal liquid becomes increasingly viscous. The telescopic end of the electric push rod 1401 moves upward, causing the fixed rod 1402 to move upward. The fixed rod 1402 then moves the sliding shell 1403 upward, which in turn moves the cleaning ring 1404 upward. During this upward movement, the sliding shell 1403 carries the viscous medicinal liquid upward, simultaneously carrying upward the bubbles generated by its evaporation. This continues until the medicinal liquid reaches the surface of the liquid. The liquid above the sliding shell 1403 then flows downward through evenly distributed holes on the sliding shell 1403 to the surface, forming evenly distributed strip-like paths. During this process, moisture in the medicinal liquid further dissipates into the air and is then extracted by a vacuum pump through a pipe on the upper side of heating tank 2. Furthermore, the medicinal residue in the liquid is removed by the sliding shell 1404. The evenly distributed through holes on the 403 intercept the dregs inside the sliding shell 1403 to prevent them from settling and being scorched. After the liquid in the sliding shell 1403 is drained, the telescopic end of the electric push rod 1401 is extended. The telescopic end of the electric push rod 1401 drives the sliding shell 1403 and the cleaning ring 1404 to move downward and reset through the fixed rod 1402. The above steps are repeated to turn the liquid up and down until the hair-darkening ointment is prepared. The fixed rod 1402 drives the sliding shell 1403 to move up and down repeatedly. The sliding shell 1403 continuously turns the liquid in the heating tank 2 vertically. After the sliding shell 1403 moves the liquid upward to the surface, the liquid in the sliding shell 1403 flows downward through the evenly distributed through holes on the sliding shell 1403 and forms an evenly distributed strip path, so that the water in the liquid can be further dispersed into the air, thereby improving the preparation efficiency of the hair-darkening ointment.

[0045] As the cleaning ring 1404 moves upward, it scrapes off the viscous liquid adhering to the side wall of the heating tank 2, thereby preventing the liquid from sticking to the side wall of the heating tank 2 and causing it to scorch, thus ensuring the quality of the liquid.
