Description

Technical Field

[0001] The utility model relates to the technical field of samarium cobalt magnets, and more specifically, to a samarium cobalt magnet structure for large detectors. Background Art

[0002] Samarium cobalt magnets, also known as samarium cobalt magnetic steel, are a type of magnetic material made by mixing samarium, cobalt and other rare earth metal materials, smelting them into an alloy, and then crushing, pressing and sintering them. They have high magnetic energy product and extremely low temperature coefficient. The maximum operating temperature can reach 350°C, and there is no limit to negative temperatures. They have strong corrosion and oxidation resistance, so they are widely used in aerospace, national defense and military industry, microwave devices, communications, medical equipment, instruments, meters, various magnetic transmission devices, sensors, magnetic processors, motors, magnetic cranes, etc.

[0003] After searching, an existing patent (publication number: CN209377615U) discloses a samarium cobalt magnet for a medical detector, comprising a main body and a magnet. The main body is provided with a shell on the outside, and a first conduit is installed inside the main body. The magnet is connected to the right end of the first conduit, and a liquid storage chamber is provided inside the magnet. The samarium cobalt magnet for the medical detector is provided with a first conduit that is connected to a second conduit through the liquid storage chamber, which facilitates the transportation of some coupling agent required for the operation of the ultrasonic detector from the first conduit to the liquid storage chamber. The entire magnet is in the shape of a cylindrical barrel, making it convenient to store coupling agent inside the liquid storage chamber, thereby improving the space utilization of the magnet. A piston plate is provided that can slide inside the magnet, and the cross-sectional shape of the piston plate is the same as the cross-sectional shape and size of the liquid storage chamber inside the magnet. Therefore, the piston plate and the magnet can be regarded as a small compression device. The sliding of the piston plate can squeeze out the coupling agent inside the liquid storage chamber. In the process of realizing this utility model, the inventor found that the existing technology has the following problems:

[0004] Existing detectors use samarium-cobalt magnets, and the required coupling agent dosage and coverage for ultrasonic detection vary depending on the purpose of treatment or detection. Excessive or insufficient coverage can affect detection. Uneven pressure applied during coupling agent application can lead to insufficient application in certain areas, resulting in localized lack of coupling agent and signal loss or detection errors. This necessitates flexible adjustment of pressure to accommodate specific needs. When heated, the coupling agent expands, generating pressure that causes it to flow back through the pipes, impacting its use. Furthermore, low temperatures during detection can increase the viscosity of the coupling agent, causing condensation, which affects its fluidity and hinders the normal operation of the device.

[0005] Therefore, in order to solve the above problems, a samarium cobalt magnet structure for large detectors is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a samarium-cobalt magnetic steel structure for a large detector to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: a samarium-cobalt magnet structure for a large detector, comprising a main body, a samarium-cobalt magnet inner layer, a samarium-cobalt magnet outer layer, and a liquid dispersion plate; a liquid storage chamber is defined in the inner cavity at the upper end of the main body; the samarium-cobalt magnet inner layer is disposed in the inner cavity at the lower end of the main body; and the samarium-cobalt magnet outer layer is disposed on the outer surface of the samarium-cobalt magnet inner layer;

[0008] A liquid outlet is provided at the center of the upper end of the liquid storage chamber, an upper sealing cover is provided at the lower end of the liquid outlet, a sealing ring is sleeved on the edge of the upper end surface of the upper sealing cover, a liquid guide tube is installed in the inner cavity of the liquid outlet, a first leakage net is provided on the outer surface of the lower end of the liquid guide tube, a spring is sleeved on the outer surface of the liquid guide tube, and a probe is connected to the upper end of the liquid guide tube, and the bulk liquid tray is provided on the upper end surface of the probe.

[0009] Preferably, a liquid inlet is provided at the center of the lower end of the liquid storage chamber, a liquid inlet sleeve is installed on the inner surface of the liquid inlet, a lower sealing cover is provided on the upper end surface of the liquid inlet sleeve, a sealing ring is installed at the edge of the lower end of the lower sealing cover, and a second leakage net is provided on the outer surface of the liquid inlet sleeve.

[0014] Technical effects and advantages of this utility model:

[0015] 1. Compared with existing technologies, this large-scale detector uses a samarium-cobalt magnetic steel structure to quickly release the coupling agent by pressing the probe and the bulk liquid disc. The user can adjust the pressure as needed to flexibly control the amount of coupling agent released to meet different operational requirements and ensure that it is evenly covered on the skin surface. When the probe is pressed to drive the upper cover, the downward pressure of the upper cover effectively drives the liquid inlet sleeve and the lower cover to close the liquid inlet, ensuring that the coupling agent does not flow back during the pressure application process, which will not lead to insufficient coupling agent dosage.

[0016] 2. Compared with the existing technology, the large-scale detector uses a samarium-cobalt magnet structure that combines the outer layer of samarium-cobalt magnet with the inner layer of samarium-cobalt magnet to form an effective double-layer thermal isolation layer, which can prevent the rapid loss of internal heat and maintain the stability of heat in the tube body. Resistance heating can quickly heat the coupling agent in the tube body, ensuring that the fluidity and viscosity of the coupling agent are optimized in cold environments or when condensation occurs, so that the coupling agent maintains a suitable temperature in a low temperature environment, reduces the occurrence of condensation, and thus improves the working efficiency of the detector.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] As attached Figures 1 to 4 The illustrated structure of a large-scale detector using a samarium-cobalt magnet comprises a main body 1, an inner samarium-cobalt magnet layer 3, an outer samarium-cobalt magnet layer 4, and a liquid dispersion plate 12. A liquid storage chamber 2 is defined within the upper inner cavity of the main body 1. The inner samarium-cobalt magnet layer 3 is disposed within the lower inner cavity of the main body 1. The outer samarium-cobalt magnet layer 4 is disposed on the outer surface of the inner samarium-cobalt magnet layer 3.

[0025] A liquid outlet 21 is provided at the center of the upper end of the liquid storage chamber 2, and an upper cover 6 is provided at the lower end of the liquid outlet 21. A sealing ring 7 is sleeved on the edge of the upper end surface of the upper cover 6. A liquid guide tube 8 is installed in the inner cavity of the liquid outlet 21, and a first leakage net 9 is provided on the outer surface of the lower end of the liquid guide tube 8. A spring 10 is sleeved on the outer surface of the liquid guide tube 8, and a probe 11 is connected to the upper end of the liquid guide tube 8. A bulk liquid tray 12 is provided on the upper end surface of the probe 11.

[0026] Among them: when in use, the coupling agent is guided into the main body 1 through the inner layer 3 of the samarium cobalt magnetic steel. The samarium cobalt magnetic steel material has excellent temperature stability, a wide range of adaptability, can maintain performance at high temperatures, and reduce the risk of demagnetization. Therefore, the outer layer 4 of the samarium cobalt magnetic steel and the inner layer 3 of the samarium cobalt magnetic steel are combined to form an effective double-layer thermal isolation layer, which can prevent the rapid loss of internal heat. Then, the coupling agent flows into the liquid storage chamber 2 through the liquid inlet 22, and is discharged through the liquid outlet 21 opened at the upper end of the liquid storage chamber 2. The spring 10 connected to one end of the liquid guide tube 8 protruding from the liquid outlet 21 provides a rebound function of the upper cover 6. When the spring 10 supports the probe 11, it will drive the liquid guide tube 8 and the upper cover 6 extend upward. Since the upper cover 6 is larger than the liquid outlet 21, it will be blocked at the liquid outlet 21 and further sealed by the sealing ring 7. When the coupling agent needs to be applied, the probe 11 and the diffusion plate 12 directly contact the skin. The user then presses it on the skin surface, so that the coupling agent can enter the catheter 8 through the first leakage net 9 and then be discharged through the diffusion plate 12 on the surface of the probe 11. The simple pressing action causes the coupling agent to flow out and be applied to the skin surface. By pressing the probe 11, the coupling agent is evenly distributed on the skin surface. The pressing force can accurately control the flow of the coupling agent to ensure the appropriate amount of release.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 4 As shown, see the following description for details:

[0029] As a preferred embodiment, a liquid inlet 22 is provided at the center of the lower end of the liquid storage chamber 2, a liquid inlet sleeve 14 is installed on the inner surface of the liquid inlet sleeve 14, a lower cover 15 is provided on the upper end surface of the liquid inlet sleeve 14, the upper cover 6 and the lower cover 15 are connected by a connecting rod 13, a sealing ring 7 is installed at the edge of the lower end of the lower cover 15, and a second leakage net 16 is provided on the outer surface of the liquid inlet sleeve 14; further, since the upper cover 6 and the lower cover 15 are connected by the connecting rod 13, When the upper cover 6 is pressed, the lower cover 15 drives the liquid inlet sleeve 14 to enter the liquid inlet 22, and abuts against the liquid inlet 22 by cooperating with the sealing ring 7, thereby closing and blocking the liquid inlet 22, ensuring that the coupling agent does not flow back during the pressure application process. When the upper cover 6 is not pressed, the probe 11 is supported by the rebound of the spring 10, thereby lifting the lower cover 15, allowing the coupling agent to smoothly pass through the second leakage net 16 into the liquid storage chamber 2, thereby maintaining the stability of liquid inlet and outlet.

[0030] As a preferred embodiment, the upper end of the spring 10 is connected to the probe 11 ; further, the spring 10 is connected to the probe 11 , keeping the spring 10 fixed, and supporting the probe 11 through the elastic performance of the spring 10 .

[0031] As a preferred embodiment, a resistance heating wire 5 is installed between the inner layer 3 of the samarium cobalt magnetic steel and the outer layer 4 of the samarium cobalt magnetic steel, and the upper end of the inner layer 3 of the samarium cobalt magnetic steel is connected to the liquid inlet 22; further, the resistance heating wire 5 converts electrical energy into thermal energy to heat between the inner layer 3 of the samarium cobalt magnetic steel and the outer layer 4 of the samarium cobalt magnetic steel.

[0032] As a preferred embodiment, the inner surface of the liquid outlet 21 abuts against the outer surface of the liquid guide tube 8, and the inner surface of the liquid inlet 22 abuts against the outer surface of the liquid inlet sleeve 14; further, the liquid inlet 22 is connected and sleeved into the liquid guide tube 8 to transport liquid.

[0033] As a preferred embodiment, the catheter 8 is connected to the probe 11, and the surface of the scattering plate 12 is distributed in a plurality of holes; further, the catheter 8 can be connected to the probe 11, and the scattering plate 12 evenly applies the coupling agent to the skin surface through the plurality of holes on the surface.

[0034] The working process of the present invention is as follows: First, the coupling agent is guided into the main body 1 through the inner layer 3 of samarium cobalt magnetic steel. The material of samarium cobalt magnetic steel has excellent temperature stability, a wide range of adaptability, and can maintain performance at high temperatures, so that the outer layer 4 of samarium cobalt magnetic steel and the inner layer 3 of samarium cobalt magnetic steel are combined to form an effective double-layer thermal isolation layer, which can prevent the rapid loss of internal heat and heat the resistance heating wire 5 in its inner cavity. Then, the coupling agent flows into the liquid storage chamber 2 through the liquid inlet 22, and is discharged through the liquid outlet 21 opened at the upper end of the liquid storage chamber 2. The spring 10 connected to one end of the liquid guide tube 8 protruding from the liquid outlet 21 provides a rebound function of the upper cover 6. When the spring 10 supports the probe 11, it will drive the liquid guide tube 8 and the upper cover 6 to extend upward. Since the upper cover 6 is larger than the liquid outlet 21, it will be blocked at the liquid outlet 21 and pass through the sealing ring 7 To further provide a seal, when coupling agent needs to be applied, the probe 11 and the diffuser 12 are in direct contact with the skin, and then the user presses it on the skin surface, so that the coupling agent can enter the liquid guide tube 8 through the first leakage net 9 and then be discharged through the diffuser 12 on the surface of the probe 11. The simple pressing action causes the coupling agent to flow out and be applied to the skin surface. Since the upper cover 6 and the lower cover 15 are connected by the connecting rod 13, when the upper cover 6 is pressed, the lower cover 15 and the liquid inlet sleeve 14 are driven to slide along the inner surface of the liquid inlet port 22. When the upper cover 6 is not pressed, the probe 11 is supported by the rebound of the spring 10, thereby lifting the lower cover 15, allowing the coupling agent to smoothly pass through the second leakage net 16 and enter the liquid storage chamber 2. The above is the working principle of the samarium cobalt magnetic steel structure for large detectors.

[0035] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
