Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically a float-type coated liquid level and viscosity sensor. Background Technology

[0002] Orthodontic appliances, also known as braces, are devices used to treat malocclusion. They generate force, or exert force through the masticatory muscles and perioral muscles, to alter the deformed jawbone, misaligned teeth, and periodontal supporting tissues, thereby promoting normal growth and development of the dentofacial region. Currently, the use of braces in orthodontic treatment creates a closed environment that leads to tooth decay. Therefore, using novel antibacterial materials coated on the surface of braces to prevent tooth decay is a current research hotspot.

[0003] The existing method for coating orthodontic appliances is generally dip coating. This involves placing the appliance in an extraction tank filled with a coating solution using a precision lifting structure, and then coating it. However, traditional dip coating devices rely on manual observation of the liquid level inside the extraction tank, making it impossible to accurately observe the viscosity of the solution. This makes it easy for the viscosity of the solution to affect the coating quality when coating the orthodontic appliances, thus affecting the product quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a float-type coating liquid level and viscosity sensor.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A float-type coated liquid level and viscosity sensor, comprising:

[0007] An extraction tank, the interior of which forms a space for holding the solution;

[0008] A graduated tube is installed through the inner wall of the extraction tank. The bottom end of the graduated tube is connected to the bottom surface of the extraction tank, and a through hole for the solution to flow is opened on one side of the bottom surface of the graduated tube.

[0009] A magnetic float is disposed inside the graduated tube;

[0010] A magnetic spring is connected to the bottom inner wall of the extraction tank, and the magnetic spring is located inside the graduated tube. When the magnetic spring is energized and generates magnetism, the magnetic float is always within the magnetic force range of the magnetic spring.

[0011] Multiple Hall sensors are arranged in an array on the outer surface of the graduated tube, and each Hall sensor is electrically connected to a timer. In the initial state, the time for the magnetic float to pass through the standard solution is preset between adjacent timers.

[0012] In this process, each timer records the time elapsed along the upward movement path of the magnetic float.

[0013] Preferably, in the initial state, the magnetic float is suspended inside the graduated tube, and when the solution enters the graduated tube, the magnetic float moves as the liquid level rises.

[0014] Preferably, the magnetic float is spherical.

[0015] Preferably, an alarm is electrically connected to the Hall sensor located near the bottom of the extraction tank. When the magnetic float floats down to the Hall sensor at the bottom, the alarm is activated when the magnetic spring is not energized.

[0016] Preferably, in the initial state, the height of the magnetic spring is consistent with the height of the through hole, and the height of the Hall sensor at the bottom is not lower than the height of the through hole.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] Hall effect sensors and magnetic floats are used to achieve visualized management of solution content. The magnetic float is attracted by a magnetic spring. By measuring the time required for the float to travel a fixed distance, the relative change in solution viscosity can be reflected indirectly and in real time, avoiding coating quality problems caused by abnormal viscosity and eliminating the generation of batch defective products from the source.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] Example

[0026] like Figure 1-3 As shown, a float-type coated liquid level and viscosity sensor includes:

[0027] Extraction tank 1, the interior of which forms a space for placing the solution;

[0028] The graduated tube 2 is installed through the inner wall of the extraction tank 1. The bottom end of the graduated tube 2 is connected to the bottom surface of the extraction tank 1, and a through hole for the solution to flow is opened on one side of the bottom surface of the graduated tube 2.

[0029] Magnetic float 3 is disposed inside the scale tube 2;

[0030] A magnetic spring 4 is connected to the bottom inner wall of the extraction tank 1, and the magnetic spring 4 is located inside the scale tube 2. When the magnetic spring 4 is energized and generates magnetism, the magnetic float 3 is always within the magnetic force range of the magnetic spring 4.

[0031] Multiple Hall sensors 5 are arranged in an array on the outer surface of the scale tube 2, and each Hall sensor 5 is electrically connected to a timer 6. In the initial state, the time for the magnetic float 3 to pass through the standard solution is preset between adjacent timers 6.

[0032] In this process, each timer 6 records the time elapsed for the magnetic float 3 along its upward movement path.

[0033] Specifically: A controller 7 is installed on the surface of the extraction tank 1. The controller 7 is electrically connected to the magnetic spring 4, multiple Hall sensors 5, and a timer 6. When there is a solution inside the extraction tank 1, the solution flows into the interior of the graduated tube 2 through the through hole at the bottom of the graduated tube 2. Due to the buoyancy of the solution, the magnetic float 3 is moved. The magnetic float 3 is always on the water surface. After detection by the Hall sensor 5, the Hall sensor 5 senses the position of the magnetic field generated by the magnetic float 3, and then converts the magnetic field at the location of the magnetic float 3 into an electrical signal, which is transmitted to the controller 7 to display the position of the magnetic float 3. The position of the magnetic float 3 can be detected in real time, thereby transmitting the liquid level data of the solution to the controller 7 and indicating the solution content inside the extraction tank 1. The solution content inside the extraction tank 1 can be known without manual observation, which can realize quantitative and visual management and avoid uneven coating depth due to the drop of the liquid level.

[0034] Further explanation: After each coating process in the extraction tank 1, the controller 7 activates the magnetic spring 4. The energized magnetic spring 4 generates a magnetic field, which attracts the magnetic float 3. The attracted magnetic float 3 is drawn into the solution and moves towards the bottom of the graduated tube 2. When the magnetic float 3 contacts the magnetic spring 4 or reaches the bottom, the controller 7 de-energizes the magnetic spring 4. The magnetic float 3, located inside the solution, moves upwards within the graduated tube 2 under the buoyancy of the solution. Each time the magnetic float 3 passes a Hall sensor 5 and a timer 6, the timer 6 records the passing time. The time is recorded and transmitted to controller 7, which displays the data. Then, the staff calculates the rising speed of magnetic float 3 based on the data transmitted back from timer 6. When the calculated speed is less than the initially set threshold, the viscosity of the solution is too high, and vice versa. At this time, the alarm is activated to remind the staff to replace the solution. In this way, by measuring the time required for magnetic float 3 to travel a fixed distance, the relative change of solution viscosity can be reflected indirectly and in real time, avoiding coating quality problems caused by abnormal viscosity and eliminating the generation of batch defective products from the source.

[0035] In this embodiment: In the initial state, the magnetic float 3 is suspended inside the scale tube 2. When the solution enters the scale tube 2, the magnetic float 3 moves as the liquid level rises.

[0036] Specifically: In the initial state, the magnetic float 3 is suspended and does not contact the bottom of the graduated tube 2 or other components, so there is no problem of "initial contact resistance" or "initial position offset". When the solution just enters the graduated tube 2, the magnetic float 3 can be directly driven to rise by buoyancy. Its initial movement point corresponds exactly to the critical liquid level of "the solution just submerges the magnetic float 3", avoiding the detection error of "the liquid level has risen but the magnetic float 3 has not moved" caused by the magnetic float 3 initially getting stuck or contacting the bottom, making the "zero starting point" of liquid level detection more accurate.

[0037] In this embodiment: the magnetic float 3 is spherical.

[0038] Specifically, the spherical structure has an optimal streamlined appearance. When moving in the liquid, whether rising with the liquid level or sinking due to adsorption by the magnetic spring 4, it significantly reduces the viscous resistance and flow resistance of the liquid on the magnetic float 3. This means that the magnetic float 3 can move more quickly following changes in liquid level or be more smoothly adsorbed to the bottom of the scale tube 2, avoiding the problem of "liquid level has changed but magnetic float 3 is lagging behind" caused by excessive resistance, ensuring timely detection response. Furthermore, the geometric symmetry of the sphere ensures that the buoyancy it experiences in the liquid is evenly distributed on the surface, preventing the magnetic float 3 from tilting, flipping, or sticking to the inner wall of the scale tube 2 due to uneven local force. The magnetic float 3 can always maintain a stable "vertical up and down" movement trajectory, and its center position can accurately correspond to the actual liquid level height, avoiding misjudgment of the position by the Hall sensor 5 due to the attitude deviation of the magnetic float 3, further improving the accuracy of liquid level and viscosity detection.

[0039] In this embodiment: The Hall sensor 5 located near the bottom of the extraction tank 1 is electrically connected to an alarm. When the magnetic float 3 floats down to the Hall sensor 5 at the bottom when the magnetic spring 4 is not energized, the alarm is activated.

[0040] Specifically: As the solution is consumed, the solution level drops, and the magnetic float 3 moves with the drop in liquid level. When the Hall sensor 5 at the bottom detects that the magnetic float 3 is at the bottom, the Hall sensor 5 transmits an electrical signal to the controller 7. The controller 7 then activates the alarm to remind staff to add solution, thus achieving timely warning of extremely low liquid levels and preventing the risk of "dry soaking".

[0041] In this embodiment: In the initial state, the height of the magnetic spring 4 is consistent with the height of the through hole, and the height of the Hall sensor 5 at the bottom is not lower than the height of the through hole.

[0042] Specifically: When the solution enters, the solution in the extraction tank 1 can flow unimpeded into the graduated tube 2 through the through hole, quickly filling the space inside the tube. This allows the magnetic float 3 to gain buoyancy and rise in time, avoiding the problem of an empty tube where "the solution cannot enter and the magnetic float 3 cannot float" due to spring obstruction. At the same time, the through hole is the lowest height at which the solution can enter the graduated tube 2. The sensor is not lower than the through hole, which means that as long as the solution can enter the graduated tube 2 through the through hole, the "effective detection level" is achieved. The magnetic float 3 can rise with the liquid level and be captured by the bottom sensor, without the blind spot of "the solution has entered the tube but the sensor is lower than the through hole and the magnetic float 3 cannot be detected".

[0043] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
