It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0041] like Figures 1 to 8 As shown, a preferred embodiment of the cosmetic liquid detection device of the present invention comprises an infusion tube 1, a light emitting element 21, a photosensitive element 22, a first control valve 31, a second control valve 32, a third control valve 33, a defective product storage container 41 and a control system; the infusion tube 1 is a transparent tube body, the liquid inlet end 11 of the infusion tube 1 is used to connect to the cosmetic liquid supply pump, and the liquid outlet end 12 of the infusion tube 1 is used to connect to the filling equipment; the cosmetic liquid supply pump can continuously pass the cosmetic liquid to be detected into the infusion tube 1, the light emitting element 21 is arranged on one side of the infusion tube 1 to emit a detection light beam to the infusion tube 1, and the photosensitive element 22 is arranged on the other side of the infusion tube 1 to receive the detection light beam passing through the infusion tube 1; the light emitting element 21 emits a detection light beam to the infusion tube 1, and the detection light beam passes through the cosmetic liquid flowing in the infusion tube 1 to realize continuous detection of the cosmetic liquid, and the cosmetic liquid after detection flows into the filling equipment for filling; the first control valve 31 and the second control valve 32 are both arranged on the infusion tube 1, and the first control valve 31, the light-emitting member 21 and the second control valve 32 are arranged in sequence along the axial direction of the infusion tube 1; in this embodiment, the liquid inlet end 11, the first control valve 31, the light-emitting member 21, the second control valve 32 and the liquid outlet end 12 are arranged in sequence along the axial direction of the infusion tube 1, the first control valve 31 and the second control valve 32 are arranged close to the light-emitting member 21, the bottom of the infusion tube 1 between the first control valve 31 and the second control valve 32 is connected to one end of the third control valve 33, and the other end of the third control valve 33 is connected to the defective product storage container 41; the first control valve 31, the second control valve 32, the third control valve 33 and the photosensitive member 22 are all electrically connected to the control system; when the detection value detected by the photosensitive member 22 is less than the set value, wherein the photosensitive member 22 is a light intensity tester, and the detection value of the photosensitive member 22 is the light intensity, the control system controls the first control valve 31 and the second control valve 32 to be closed, and controls the third control valve 33 to be opened. When the cosmetic liquid containing impurities flows through the detection area of ​​the light-emitting component 21, due to the obstruction of the impurities, the light intensity detected by the photosensitive component 22 will be less than the first set value. At this time, the control system controls the first control valve 31 and the second control valve 32 to be closed, thereby trapping the cosmetic liquid containing impurities in the infusion tube 1 located between the first control valve 31 and the second control valve 32. At this time, the third control valve 33 is opened, and the cosmetic liquid trapped in the infusion tube 1 flows into the defective product storage container 41 through the third control valve 33, which not only realizes the detection of impurities, but also realizes the separate removal of the cosmetic liquid containing impurities. In addition, the structure of the cosmetic liquid detection device is simple, and there is no need to use a complex driving mechanism 216 to drive the light-emitting component 21.

[0042] The infusion tube 1 between the first control valve 31 and the second control valve 32 is defined as the interception section, and the cosmetic liquid detection device further includes a good product storage container 42 and a good product delivery pump 43, one end of the good product delivery pump 43 is connected to the good product storage container 42, and the other end of the good product delivery pump 43 is connected to the infusion tube 1 between the first control valve 31 and the second control valve 32. After all the cosmetic liquid containing impurities in the interception section flows into the defective product storage container 41, the interception section is a cavity. In order to avoid the cosmetic liquid on the other side of the first valve from instantly flowing into the interception section after the first valve is opened, causing turbulence and mixing of air into the infusion tube 1, in this embodiment, after the cosmetic liquid containing impurities in the interception section is emptied, the good product delivery pump 43 is used to inject impurity-free cosmetic liquid into the interception section. After the impurity-free cosmetic liquid fills the interception section, the first control valve 31 is opened again, thereby ensuring the stability of the liquid flow in the infusion tube 1, thereby ensuring the detection accuracy.

[0043] Furthermore, in order to ensure that the impurity-free cosmetic liquid can completely fill the retention section, in this embodiment, the cosmetic liquid detection device also includes an overflow pipe 44, which is connected to the infusion tube 1 located between the first control valve 31 and the second control valve 32, and the overflow pipe 44 is connected to the fourth control valve 34 and the first flow meter 51, and the fourth control valve 34 and the first flow meter 51 are arranged in sequence from close to the infusion tube 1 to away from the infusion tube 1; the fourth control valve 34 and the first flow meter 51 are both electrically connected to the control system, and the setting position of the first flow meter 51 is higher than the position of the retention section. When the detection value of the first flow meter 51 is greater than the second set value, it means that the impurity-free cosmetic liquid has completely filled the retention section. At this time, the control system controls the fourth control valve 34 to close, thereby achieving sealing of the retention section.

[0044] In this embodiment, the first control valve 31, the second control valve 32, the third control valve 33 and the fourth control valve 34 are all electromagnetic valves. The end of the overflow pipe 44 away from the infusion tube 1 is connected to the good product storage container 42, so as to realize the recovery of the impurity-free cosmetic liquid flowing from the overflow pipe 44, and the recovered impurity-free cosmetic liquid can be used to fill the interception section again.

[0045] In this embodiment, in order to facilitate the judgment of whether the cosmetic liquid containing impurities in the retention section has been completely drained, the cosmetic liquid detection device also includes a drain pipe 45 and a second flow meter 52 arranged on the drain pipe 45; the first end of the drain pipe 45 is connected to the infusion tube 1 located between the first control valve 31 and the second control valve 32, and the second end of the drain pipe 45 is connected to the defective product storage container 41; the third control valve 33 is arranged on the drain pipe 45, and the first end of the drain pipe 45, the third control valve 33, the second flow meter 52 and the second end of the drain pipe 45 are arranged in sequence; the second flow meter 52 is electrically connected to the control system, and when the detection value of the second flow meter 52 is less than the third set value, the control system controls the third control valve 33 to close.

[0046] In this embodiment, the cosmetic liquid detection device also includes a three-way pipe joint 7, the first joint of the three-way pipe is connected to the bottom of the interception section, the discharge pipe 45 is connected to the second joint of the three-way pipe, and the good product delivery pump 43 is connected to the third joint of the three-way pipe through a pipeline.

[0047] In order to further ensure the stable flow of the cosmetic liquid in the infusion tube 1, in this embodiment, the cosmetic liquid detection device further includes a first liquid pressure sensor 61 and a second liquid pressure sensor 62. The first liquid pressure sensor 61 is arranged between the liquid inlet end 11 and the first control valve 31, and the second liquid pressure sensor 62 is arranged between the first control valve 31 and the second control valve 32, and the second control valve 32 is arranged away from the light-emitting member 21. The first liquid pressure sensor 61, the second liquid pressure sensor 62 and the good product delivery pump 43 are all electrically connected to the control system, and the control system controls the good product delivery pump 43 to deliver liquid into the infusion tube 1 so that the difference between the test values ​​of the second liquid pressure sensor 62 and the first liquid pressure sensor 61 is within a set range.

[0048] In this embodiment, the light-emitting component 21 includes a condenser 211 and a light source 212 arranged in the condenser 211. The condenser 211 is provided with a light outlet 213 arranged opposite to the light source 212. The light outlet 213 is rectangular, and the length direction of the light outlet 213 is perpendicular to the axial direction of the infusion tube 1. The condenser 211 has a hemispherical inner cavity, and the light source 212 is arranged in the hemispherical inner cavity, so that the light emitted by the light source 212 can vertically pass through the light outlet 213.

The first light baffle 214 and the second light baffle 215 are arranged relatively spaced along the length direction of the light outlet 213. The light-emitting component 21 also includes a driving mechanism 216 for driving the first light baffle 214 and the second light baffle 215 to move closer to or away from each other. By using the driving mechanism 216 to adjust the distance between the first light baffle 214 and the second light baffle 215, the length of the light outlet 213 can be made the same as the diameter of the infusion tube 1, so that the detection light beam emitted from the light outlet 213 is fully irradiated to the infusion tube 1, avoiding the decrease in detection accuracy caused by the distribution range of the detection light beam being larger than the diameter of the infusion tube 1.

[0049] Specifically, the driving mechanism 216 includes an adjusting screw 2161, a first protruding portion 2162 disposed on the outer side of the first light baffle 214, and a second protruding portion 2163 disposed on the outer side of the second light baffle 215.

A first thread segment 21611 and a second thread segment 21612 are disposed on the outer side of the adjusting screw 2161. The thread rotation direction of the first thread segment 21611 and the thread rotation direction of the second thread segment 21612 are opposite. The first thread segment 21611 is matched and inserted in the first threaded hole, and the second thread segment 21612 is matched and inserted in the second threaded hole. By rotating the adjusting screw 2161, the spacing between the first light baffle 214 and the second light baffle 215 can be adjusted to achieve the adjustment of the light beam profile emitted by the light emitting element 21.

[0050] Furthermore, in the present embodiment, one end of the first protrusion 2162 facing the second protrusion 2163 is flush with one end of the first light baffle 214 facing the second baffle; one end of the second protrusion 2163 facing the first protrusion 2162 is flush with one end of the second light baffle 215 facing the first light baffle 214; one end of the first protrusion 2162 and one end of the second protrusion 2163 facing away from the focusing cover 211 both extend in a direction close to the photosensitive element 22, and the infusion tube 1 is passed through the gap between the first protrusion 2162 and the second protrusion 2163. In this embodiment, the infusion tube 1 is arranged horizontally, the first protrusion 2162 and the second protrusion 2163 are both located on the plate body, the first protrusion 2162 and the second protrusion 2163 are arranged relatively spaced apart from each other, the upper end of the infusion tube 1 in the diameter direction abuts against the lower end of the first protrusion 2162, and the lower end of the infusion tube 1 in the diameter direction abuts against the upper end of the second protrusion 2163. At this time, the detection light beam emitted by the light-emitting component 21 just completely covers the infusion tube 1, so that the outline size of the detection light beam emitted by the light-emitting component 21 can be adjusted easily.

[0051] In this embodiment, in order to avoid interference of ambient light on the photosensitive element 22, the cosmetic liquid detection device also includes a light shield 9, a mounting cavity is provided in the light shield 9, a mounting seat 82 is provided on the bottom wall of the mounting cavity, the light emitting element 21 and the photosensitive element 22 are relatively arranged on the mounting seat 82 front and back, and the light shield 9 can block the ambient light.

By adjusting the lifting device 81, the height of the photosensitive member 22 and the light-emitting member 21 can be adjusted synchronously, thereby adjusting the height position of the first protrusion 2162 and the second protrusion 2163, so that the infusion tube 1 can be located at the center of the interval between the first protrusion 2162 and the second protrusion 2163, so that the cosmetic liquid detection device of the present invention can be applicable to multiple groups of infusion tubes 1. In this embodiment, the lifting device 81 adopts a screw slider lifting mechanism, and the mounting seat is connected to the slider of the screw slider lifting mechanism. In other embodiments of the present invention, the lifting device can adopt a hydraulic cylinder.

[0053] An embodiment of a cosmetic liquid filling line includes the above-mentioned cosmetic liquid detection device, and also includes a cosmetic liquid delivery pump and a filling device.

[0055] The first protrusion 2162 and the second protrusion 2163 are adjusted to respectively abut against the upper end and the lower end of the infusion tube 1 by adjusting the screw 2161, and then the control system controls the cosmetic liquid supply pump to start, continuously introduces cosmetic liquid into the infusion tube 1, and keeps the liquid outlet flow rate of the filling line the same as the liquid outlet flow rate of the cosmetic liquid supply pump. When the test value of the photosensitive member 22 is less than a set value, the control system controls the cosmetic liquid supply pump and the filling equipment to stop operating, and controls the first control valve 31 and the second control valve 32 to close, and the third control valve 33 and the fourth control valve 34 to open. At this time, the overflow pipe 44 performs ventilation to prevent the cosmetic liquid in the retention section from being unable to flow out due to negative pressure, and the cosmetic liquid in the retention section flows out through the discharge pipe 45. into the defective product storage container 41; when the detection value of the second flow meter 52 is less than the third set value, the control system controls the third control valve 33 to close, and controls the good product delivery pump 43 to start, and passes the impurity-free cosmetic liquid into the retention section until the detection value of the first flow meter 51 is greater than the second set value, the control system controls the fourth control valve 34 to close, at which time the retention section is completely filled with impurity-free cosmetic liquid, and the control system controls the infusion volume of the good product infusion pump so that the detection value of the second liquid pressure sensor 62 is the same as the detection value of the first liquid pressure sensor 61, and then opens the first control valve 31 and the second control valve 32, and starts the cosmetic liquid supply pump and the filling equipment to realize the detection and filling of the subsequent cosmetic liquid.

[0056] In summary, the cosmetic liquid detection device of the present invention not only realizes the detection of impurities, but also realizes the separate removal of cosmetic liquid containing impurities.
