Description

Technical Field

[0001] This utility model relates to the field of body oil measurement technology, specifically to a body oil viscosity testing device. Background Technology

[0002] Body oil is an oil-based skincare product used for body care. It is primarily composed of plant oils or mineral oils and forms a protective film on the skin's surface, providing moisturizing, hydrating, and repairing benefits. With increasing demands for skincare, body oil has gradually become an important choice for body care due to its excellent water-locking ability and multi-functionality.

[0003] Body oil viscosity testing is a key indicator for evaluating its fluidity and lubricating properties, primarily achieved by measuring the internal molecular frictional resistance of the oil. Existing body oil viscosity testing methods include the ramp flow method and the pipette timing method. The ramp flow method involves dropping body oil and glycerin onto an inclined glass plate; the slower the flow rate, the higher the viscosity. The pipette timing method records the time it takes for an equal volume of oil sample to flow through a pipette; the longer the time, the higher the viscosity. Existing ramp flow methods use a fixed ramp, which cannot be adjusted at multiple angles, thus failing to meet the viscosity testing needs of body oils with varying viscosities. Furthermore, the temperature of the ramp surface cannot be adjusted, making it difficult to accurately simulate human skin temperature. Therefore, it is necessary to propose a body oil viscosity testing device with an adjustable ramp and adjustable ramp surface temperature. Summary of the Invention

[0004] To address the aforementioned shortcomings of the existing technology, this utility model provides a body oil viscosity testing device.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: it includes a U-shaped chute, a base, a steel ball, and a PLC controller. The bottom of the U-shaped chute is hinged to the base via a hinge shaft. A water bath heating box is fitted to the bottom of the U-shaped chute, and an electric heating rod is installed inside the water bath heating box. A release component for releasing the steel ball is installed at the upper end of the U-shaped chute, and a blocking component for blocking the steel ball is installed at the lower end of the U-shaped chute. An angle adjustment support is provided between the U-shaped chute and the base.

[0006] Furthermore, the release assembly includes an upper toggle shaft rotatably mounted on a U-shaped slide and a toggle plate fixed on the upper toggle shaft, with a toggle switch fixedly connected to one end of the upper toggle shaft.

[0007] Furthermore, a first trigger switch is provided on the U-shaped slide to cooperate with the toggle plate, and the first trigger switch is electrically connected to the PLC controller.

[0008] Furthermore, the blocking assembly includes a detachable lower blocking plate and a movable plate, which are connected by several springs. The U-shaped slide is provided with a slot that mates with the lower blocking plate.

[0009] Furthermore, a second trigger switch is provided on the lower blocking plate, and the second trigger switch is electrically connected to the PLC controller.

[0010] Furthermore, the angle adjustment support includes an adaptive support block, an adaptive rotating shaft, and a U-shaped support base. The adaptive support block is rotatably mounted on the U-shaped support base via the adaptive rotating shaft, and the adaptive support block is provided with a horizontal part that cooperates with the U-shaped groove.

[0011] Furthermore, the base is provided with a sliding protrusion, and the adaptive support block is provided with a bottom groove that cooperates with the sliding protrusion.

[0012] Furthermore, both the bottom of the U-shaped support and the upper surface of the base are provided with an anti-slip rubber layer.

[0013] Furthermore, an angle sensor is installed between one end of the hinge shaft and the base, and the angle sensor is electrically connected to the PLC controller.

[0014] Furthermore, a temperature sensor is installed on the water bath heating box, and the temperature sensor is electrically connected to the PLC controller.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model's body oil viscosity testing device uses a steel ball of fixed size and weight, along with a body oil layer applied to a U-shaped chute. The U-shaped chute allows adjustment of the steel ball's falling angle and the body oil layer's temperature via a water bath heating chamber. By measuring the steel ball's falling time at different tilt angles and temperatures, the device can be used to test body oil viscosity and evaluate its fluidity and lubrication properties.

[0017] This utility model's water bath heating box, in conjunction with a heating rod, can heat the water inside the water bath heating box. The water bath heating box transfers heat to the U-shaped slide through heat transfer, thereby preheating the body oil layer applied to the U-shaped slide to the set test angle. For example, the surface temperature of the U-shaped slide can be adjusted to be the same as that of human skin, thus better simulating the viscosity test of body oil at the actual human body temperature. At the same time, in conjunction with the temperature sensor set on the water bath heating box, the U-shaped slide and the body oil layer are kept within the set test temperature range.

[0018] The bottom of the U-shaped slide of this utility model is provided with an angle adjustment support, and the angle adjustment support is provided with an adaptive support block that cooperates with the bottom of the U-shaped slide. By moving the angle adjustment support, the position of the support is adjusted, thereby achieving adaptive support for the bottom of the U-shaped slide through the adaptive support block. At the same time, the anti-slip rubber layer on the bottom of the U-shaped slide and the base is used to achieve frictional self-locking of the angle.

[0019] The upper end of the U-shaped chute of this invention has a lever that can release the steel ball. At the same time, the lever can trigger a first trigger switch, so that when the steel ball falls, it starts timing the steel ball in conjunction with a timer. The lower end of the U-shaped chute has a movable plate and a second trigger switch. When the steel ball falls and hits the movable plate, it triggers the second trigger switch. The second trigger switch, in conjunction with the timer, stops timing the steel ball, so that the falling time of the steel ball can be obtained by collecting the timer data.

[0020] This invention can maintain a constant temperature of the body oil layer on the U-shaped slide by controlling the temperature of the water bath heating box, and change the temperature of the body oil layer on the U-shaped slide, thereby changing the fluidity of the body oil layer.

[0021] This invention reflects the viscosity of body oil by testing its fluidity at different temperatures and angles, and evaluates the fluidity and lubrication performance of the body oil by measuring the falling time of a steel ball. Attached Figure Description

[0026] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0027] like Figure 1 and 2As shown, the body oil viscosity testing device includes a U-shaped chute 1, a base 4, a steel ball 5, and a PLC controller. The bottom of the U-shaped chute 1 is hinged to the base 4 via a hinge shaft 19. An angle sensor 6 is installed between one end of the hinge shaft and the base 4. The angle sensor 6 is electrically connected to the PLC controller. The angle sensor 6 is used to collect the tilt angle of the U-shaped chute 1, thereby facilitating the adjustment of the angle of the U-shaped chute 1 to perform body oil viscosity tests at different tilt angles. A water bath heating chamber 2 is fitted against the bottom of the U-shaped chute 1. Both the U-shaped chute 1 and the water bath heating chamber 2 are preferably made of stainless steel. An electric heating rod is installed inside the water bath heating chamber 2 and is electrically connected to the PLC controller. A temperature sensor 7 is installed on the water bath heating chamber 2 and is electrically connected to the PLC controller. The water bath heating box 2 heats the water, and the water bath heating box 2 transfers the temperature to the U-shaped slide 1 through heat transfer, so that the body oil applied on the U-shaped slide 1 is within the experimental range. The temperature sensor 7 is used to collect the water temperature in the water bath heating box 2 in real time, so as to work with the PLC controller to heat the water temperature in the water bath heating box 2 to the set temperature.

[0028] A release assembly for releasing the steel ball 5 is provided at the upper end of the U-shaped slide 1. The release assembly is used to control the release of the steel ball. The release assembly includes an upper actuating shaft 11 rotatably mounted on the U-shaped slide 1 and a lever 12 fixed on the upper actuating shaft 11. One end of the upper actuating shaft 11 is fixedly connected to a toggle switch 13. A first trigger switch 14 that cooperates with the lever 12 is provided on the U-shaped slide 1. The first trigger switch 14 is connected to a timer and electrically connected to a PLC controller. Specifically, the upper actuating shaft 11 and the lever 12 are rotated by the toggle switch 13. When the lever 12 rotates to a position parallel to the U-shaped slide 1, the lever 12 triggers the first trigger switch 14. At the same time, the steel ball 5 loses the obstruction of the lever 12 and slides down the U-shaped slide 1, thus starting the rolling timer of the steel ball 5.

[0029] A blocking assembly for blocking steel balls 5 is provided at the lower end of the U-shaped chute 1. The blocking assembly is used to block the falling steel balls 5. The blocking assembly includes a detachable lower blocking plate 15 and a movable plate 16. The lower blocking plate 15 and the movable plate 16 are connected by several springs 17. The U-shaped chute 1 is provided with a slot that mates with the lower blocking plate 15, allowing the lower blocking plate 15 to be easily installed on the U-shaped chute 1. A second trigger switch 18 is provided on the lower blocking plate 15, and the second trigger switch 18 is electrically connected to the PLC controller. Specifically, when the steel ball 5 falls along the U-shaped chute 1, the steel ball 5 impacts the movable plate 16, causing the movable plate 16 to move downward and trigger the second trigger switch 18. The second trigger switch 18, in conjunction with a timer, stops the timing, and the timing time of the timer is the timing time of the steel ball 5.

[0030] An angle-adjustable support 3 is provided between the U-shaped slide 1 and the base 4. The angle-adjustable support 3 includes an adaptive support block 31, an adaptive rotating shaft 32, and a U-shaped support base 33. The adaptive support block 31 is rotatably mounted on the U-shaped support base 33 via the adaptive rotating shaft 32. The adaptive support block 31 has a horizontal part that mates with the U-shaped slide 1. A sliding protrusion 41 is provided on the base 4, and a bottom groove that mates with the sliding protrusion 41 is provided on the adaptive support block 31. The adaptive support block 31 can slide linearly on the base 4 through the bottom groove and the sliding protrusion 41. By adaptively rotating to adapt to the bottom of the U-shaped slide 1, the adaptive support block 31 supports the U-shaped slide 1 after angle adjustment, allowing the angle of the U-shaped slide 1 to be adjusted. Anti-slip rubber layers are provided on the bottom of the U-shaped support base 33 and the upper surface of the base 4. The friction between the anti-slip rubber layers can achieve self-locking of the U-shaped slide 1 after angle adjustment, thereby preventing the angle of the U-shaped slide 1 from changing during the experiment. The PLC controller is also connected to a digital display module 8, which is used to display the temperature of the digital display module 2 and the tilt angle of the U-shaped slide 1.

[0031] An oil collection tank is provided at the bottom of the U-shaped chute 1. The oil collection tank is used to collect the body oil falling from the U-shaped chute 1. The body oil layer on the U-shaped chute 1 can be poured evenly from the U-shaped chute 1, so that the body oil layer automatically adheres to the U-shaped chute 1 to form a body oil layer.

[0032] Working process and principle: S1. Before the experiment, adjust the position of the sliding angle adjustment support 3 to adjust the U-shaped slide 1 to the experimental angle. Specifically, the angle data collected by the angle sensor 6 is displayed in real time on the digital display module 2. Adjust the position of the support 3 by moving the angle adjustment on the digital display module 2. At the same time, adjust the temperature of the water bath heating box 2 to adjust the U-shaped slide 1 to the preset temperature. S2. After the angle adjustment of the U-shaped slide 1 is completed, apply a set thickness of body oil to the upper surface of the U-shaped slide 1 and spread it evenly on the rolling path of the steel ball 5. S3. During the experiment, place the steel ball 5 on the U-shaped slide 1 and limit and block the steel ball 5 with the toggle plate 12. S4. By rotating the toggle switch 13, the toggle plate 12 is rotated to a position parallel to the upper surface of the U-shaped slide 1. At this time, the first trigger switch 14 is triggered to control the timer to start timing. At the same time, after the steel ball 5 loses the blocking effect of the toggle plate 12, the steel ball 5 rolls down from the U-shaped slide 1. The time it takes for the steel ball 5 to fall will vary depending on the viscosity of the body oil on the U-shaped slide 1. S5. The steel ball 5 rolls to the bottom position and hits the movable plate 16, thereby triggering the second trigger switch 18. The second trigger switch 18 controls the timer to stop timing, and the timer obtains the falling time of the steel ball 5. S6. After the body oil is applied to the U-shaped groove 1 and leveled, the steel ball 5 is dried. Steps S3-S5 are repeated. When it is necessary to adjust the angle and temperature of the U-shaped groove 1, specifically, the angle of the U-shaped groove 1 is adjusted by moving the position of the angle adjustment support 3, and the temperature of the U-shaped groove 1 is adjusted to the preset temperature by adjusting the temperature of the water bath heating box 2. This utility model can use a steel ball 5 of fixed size and weight, in conjunction with the body oil layer applied to the U-shaped groove 1. The falling angle of the steel ball 5 can be adjusted by the U-shaped groove 1, and the temperature of the body oil layer can also be adjusted by the water bath heating box 2. By measuring the falling time of the steel ball 5, and based on the falling time of the body oil layer at different tilt angles and temperatures, it can be used for body oil viscosity testing to evaluate the fluidity and lubrication performance of the body oil.
