Description

Technical Field

[0001] This utility model relates to the field of magnetic stimulation equipment technology, specifically to a liquid-cooled main unit and a magnetic stimulation therapy device. Background Technology

[0002] In magnetic stimulation devices, the stimulation coil is usually cooled by a liquid cooling unit. When troubleshooting, maintaining the whole machine, or changing the water, it is often necessary to drain and / or refill the water tank in the liquid cooling unit.

[0003] In related technologies, a liquid level window is typically installed on the outer side of the rear casing of the liquid cooling unit. The top of the liquid level window has a water inlet, the bottom has a drain outlet, and an air vent is located above the water inlet. The lower end of the liquid level window is connected to the lower end of the water tank via inlet and outlet pipes, while the air vent is connected to the upper end of the water tank via a pressure relief pipe. During the water tank filling process, external water enters the liquid level window through the water inlet at the top, then flows into the water tank through the inlet and outlet pipes. Air at the top of the water tank is expelled through the air vent, thus filling the tank. When the water level in the tank reaches the height of the pressure relief pipe, water flows from the tank back to the liquid level window through the pressure relief pipe and the air vent.

[0004] However, because the inner cavity of the liquid level window is generally small, the diameter of the inlet and outlet water pipes connecting the lower end of the liquid level window and the water tank is also relatively small. The water flow speed in the inlet and outlet water pipes is relatively slow. In actual water filling process, the water level in the liquid level window is usually higher than the water level in the water tank. The vent at the top of the liquid level window is easily blocked, which prevents the air at the top of the water tank from being discharged. The air at the top of the water tank forms high pressure, making it difficult to add water to the water tank, and the water filling speed is very slow. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problems of difficulty in adding water and slow water addition speed in the liquid-cooled host of the magnetic stimulation device, thereby providing a liquid-cooled host and magnetic stimulation therapy device.

[0006] In a first aspect, this application provides a liquid-cooled main unit for a magnetic stimulation therapy device, comprising:

[0007] Main unit casing;

[0008] The water tank is located inside the main unit housing;

[0009] A sight glass is connected to the main unit housing. The sight glass has a vent and a vent. The vent is located above the sight glass and is open to the outside atmosphere. A first connecting pipe connects the vent and the water tank. When the water level in the water tank is lower than the height of the first connecting pipe, the first connecting pipe allows air in the water tank to be discharged through the vent. When the water level in the water tank is higher than the height of the first connecting pipe, the first connecting pipe allows water in the water tank to be discharged to the sight glass through the vent.

[0010] The water supply and drainage pipe has one end connected to the water tank and the other end located outside the main unit housing; the water supply and drainage pipe allows external water to enter the water tank.

[0011] In some embodiments, the water supply and drainage pipeline includes a partially or wholly flexible pipe body.

[0012] In some embodiments, a sealing plug is detachably and sealingly connected to the inlet and outlet of the water supply and drainage pipeline.

[0013] In some embodiments, the flexible tube includes a first tube segment located inside the main housing and a second tube segment located outside the main housing, the water inlet and outlet being located in the second tube segment, and the second tube segment being detachably connected to the outer wall of the main housing by a fastener.

[0014] In some embodiments, the second pipe segment has a first state in which it is fixed to the main housing by the fastener, and a second state in which it is released from the main housing;

[0015] When the second pipe section is in the first state, the height of the inlet and outlet of the water supply pipe is not lower than the height of the vent, and external water can enter the water tank through the inlet and outlet of the water supply pipe.

[0016] When the second pipe section is in the second state, the height of the inlet and outlet of the water supply pipe is not higher than the bottom height of the water tank, and the water in the water tank can be discharged outward through the inlet and outlet of the water supply pipe.

[0017] In some embodiments, the sight tube is provided with a sight window for observing the liquid level in the sight tube, and the sight window is provided with an upper limit water level scale for indicating that the water tank is full.

[0018] In some embodiments, the sight glass is further provided with an inlet and an outlet, and a second connecting pipe is connected between the inlet / outlet and the water tank. The height of the second connecting pipe is lower than the height of the first connecting pipe. The second connecting pipe is used to keep the liquid level in the water tank and the sight glass consistent. The height of the first section of the flexible tube is lower than the height of the second connecting pipe.

[0019] In some embodiments, the water supply and drainage pipeline further includes a water supply auxiliary pipeline, the lower end of which is located inside the sight glass, the lower opening of which is connected to the inlet and outlet, and the upper opening of which is located outside the sight glass; the water supply auxiliary pipeline can supply water to the water tank through the second connecting pipeline.

[0020] In some embodiments, the upper opening of the water supply auxiliary pipeline is connected to a conical cylinder with a large upper opening and a small lower opening.

[0021] In some embodiments, the sight glass is further provided with inlet and outlet ports, and a second connecting pipe connects the inlet and outlet ports to the water tank. The height of the inlet and outlet ports is lower than the height of the vent, and the height of the second connecting pipe is lower than the height of the first connecting pipe. The water filling and draining pipes include a water filling auxiliary pipe. One end of the water filling auxiliary pipe extends into the sight glass from the vent, the lower opening of the water filling auxiliary pipe is connected to the inlet and outlet ports, and the upper opening of the water filling auxiliary pipe is located outside the sight glass. The upper opening of the water filling auxiliary pipe is the water filling and draining pipe inlet. During the water filling process, water directly enters the water tank through the water filling auxiliary pipe, the inlet and outlet ports of the sight glass, and the second connecting pipe. Water does not directly enter the interior of the sight glass, thus avoiding the problem of clogging the vent at the top of the sight glass during water filling and improving the water filling speed of the water tank. Once the water level in the tank reaches the set height, the water will flow through the first connecting pipe to the sight glass, allowing the system to determine whether the water level in the tank has reached the set height based on the water level in the sight glass.

[0022] Secondly, this application provides a magnetic stimulation therapy device, which includes a stimulation host; a stimulation coil assembly connected to the stimulation host for performing magnetic stimulation therapy on a target area of ​​a patient; and a liquid-cooled host of the magnetic stimulation therapy device as described in the above embodiments, connected to the stimulation coil assembly for cooling the stimulation coil assembly.

[0023] The present invention has the following advantages: a sight glass is provided on one side of the main unit housing, and the vent of the sight glass is connected to the water tank through a first connecting pipe, and a water supply and drainage pipe is provided connected to the water tank; during the process of adding water to the water tank, water is added to the water tank through the water supply and drainage pipes, and the air in the water tank will be discharged to the sight glass through the vent, and then discharged outward through the vent above the sight glass, thereby avoiding excessive air pressure in the water tank, facilitating the addition of water to the water tank, and improving the water filling speed; when the water level inside the water tank is higher than the vent, the water in the water tank will flow to the sight glass through the first connecting pipe, causing the water level in the sight glass to rise, making it easy to judge the water level in the water tank by observing the water level in the sight glass. Compared to existing technologies where water is added to the sight tube through a vent above the sight tube and the water in the sight tube flows into the water tank through the inlet and outlet at the bottom, this liquid-cooled main unit of the magnetic stimulation therapy device does not block the vent of the sight tube during the water filling process. The air inside the water tank is less likely to form a high-pressure environment, thus avoiding the problem of difficulty in adding water to the water tank and facilitating a faster water filling speed.

[0033] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] Magnetic stimulation therapy is a medical device that uses magnetic fields for non-invasive treatment. It can be used for the diagnosis and treatment of neurological and mental diseases. Its working principle is to generate induced current in human tissues through rapidly changing magnetic fields, which stimulate nerve cells and thus regulate nerve activity.

[0037] A magnetic stimulation therapy device may include a magnetic stimulation unit and a stimulation coil device. The stimulation coil device can be electrically connected to the magnetic stimulation unit and is used to perform magnetic stimulation therapy on target areas of the patient, such as the pelvic floor, head, sacral nerves, or other peripheral muscles and nerves. The magnetic stimulation unit is used to discharge the stimulation coil to generate a pulsed magnetic field.

[0038] Because magnetic stimulation therapy devices use high voltage and high current to generate a magnetic field, the stimulation coil device generates a significant amount of heat during operation. Therefore, a water tank needs to be installed inside the liquid-cooled main unit to provide cooling water for the stimulation coil device and reduce its temperature. Simultaneously, since the cooling water comes into contact with high voltage, deionized water is used to ensure electrical safety and prevent high voltage leakage. During use, microorganisms gradually grow in the cooling water, causing it to gradually become conductive. These microorganisms can also adhere to the pipes and pumps, leading to blockages. Therefore, to ensure water quality and normal equipment operation, the cooling water in the tank needs to be replaced regularly, especially in areas with high average temperatures. Each time water is added or drained, maintenance personnel are required, which is difficult, inconvenient, and costly for users. To solve these problems, this application provides a liquid-cooled main unit for a magnetic stimulation therapy device with fast water addition and drainage speed.

[0039] like Figure 1 - Figure 5 The diagram shows a liquid-cooled main unit of a magnetic stimulation therapy device, used to cool the stimulation coil device 83. The liquid-cooled main unit includes a main unit housing 1 and components such as a water pump 81, heat exchanger 82, compressor 84, condenser 85, expansion valve 86, control board, and power supply disposed inside the housing 1. The water tank 2, water pump 81, stimulation coil device 83, and heat exchanger 82 are connected by pipelines to form a cooling water circulation loop.

[0040] like Figure 2 - Figure 5 As shown, water pump 81 drives the cooling water in water tank 2 to flow to the inlet of stimulation coil device 83. After cooling the coil, the cooling water becomes warm water and flows back to the warm water inlet of the transducer through the outlet of stimulation coil device 83. After being cooled in the transducer, the warm water becomes cooling water again and flows back to water tank 2 through the cold water outlet, completing the circulation of cooling water between water tank 2 and stimulation coil device 83. Compressor 84, condenser 85, throttle valve 86 and heat exchanger 82 form a coolant circulation loop.

[0041] like Figure 2 - Figure 5As shown, the refrigerant in the heat exchanger 82 absorbs heat and becomes a low-temperature, low-pressure gas, which enters the compressor 84 through the refrigerant outlet. After being compressed by the compressor 84, the low-temperature, low-pressure gas becomes a high-temperature, high-pressure gas and enters the condenser 85. After being cooled by the condenser 85, the high-temperature, high-pressure gas becomes a medium-temperature, medium-pressure liquid. After passing through the throttling valve 86, the medium-temperature, medium-pressure liquid becomes a low-temperature, low-pressure liquid and flows to the refrigerant inlet of the heat exchanger 82. The low-temperature, low-pressure liquid absorbs heat from the circulating water in the heat exchanger 82 and becomes a low-temperature, low-pressure gas, thus completing the circulation of the refrigerant.

[0042] like Figure 2 and Figure 3 As shown, in some embodiments, to reduce the frequency of cooling water replacement in the water tank 2, this application also provides a UV lamp 21 at the top of the water tank 2. The UV lamp 21 is used to sterilize the cooling water in the water tank 2. After starting the machine each day, the main control activates the UV lamp 21 to kill bacteria, and after running for a period of time, the UV lamp 21 is turned off. The duration of the UV lamp 21's operation is related to the amount of water in the water tank 2. By purifying and sterilizing the cooling water in the water tank 2 with the UV lamp 21, the reproduction rate of microorganisms in the cooling water can be reduced, thus reducing the frequency of cooling water replacement in the water tank 2. This eliminates the need for frequent filling and draining by the user, reducing user costs and improving ease of use. A partition is provided between the UV lamp 21 and the liquid level sensor in the water tank 2. The partition is used to block ultraviolet rays, thereby preventing damage to the liquid level sensor. The partition can be made of stainless steel to avoid rusting due to immersion in water, which would affect water quality.

[0043] like Figure 1 , Figure 2 and Figure 6 As shown, a sight glass 3 is externally connected to the main housing 1, used to observe the water level in the water tank 2. The sight glass 3 has a vent 31, a vent 32, and an inlet / outlet 33. The vent 31 is located at the top of the sight glass 3 and is open to the outside atmosphere; the vent 32 is located on the upper side of the sight glass 3, and a first connecting pipe 41 connects the vent 32 and the water tank 2; the inlet / outlet 33 is located on the lower side of the sight glass 3, and a second connecting pipe 42 connects the inlet / outlet 33 and the water tank 2. (Combined with...) Figure 7The sight tube 3 has a sight window 34 on its side wall for observing the liquid level. The sight tube 3 is made of transparent material. The sight window 34 has an upper limit water level mark to indicate that the water tank 2 is full. When the water level in the water tank 2 is lower than the height of the first connecting pipe 41, the first connecting pipe 41 acts as a pressure equalization pipe between the water tank 2 and the sight tube 3, allowing air in the water tank 2 to be discharged to the sight tube 3 through the vent 32. When the water level in the water tank 2 is higher than the height of the first connecting pipe 41, the first connecting pipe 41 allows water in the water tank 2 to be discharged to the sight tube 3 through the vent 32, causing the water level in the sight tube 3 to rise until it reaches the upper limit water level mark of the sight window 34, thus indicating to the user that the water tank 2 is full.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, the liquid cooling unit also includes a water supply and drainage pipe for adding water to the water tank 2 inside the liquid cooling unit. One end of the water supply and drainage pipe is connected to the water tank 2, and the other end of the water supply and drainage pipe is located outside the main unit housing 1. The water supply and drainage pipe allows external water to enter the water tank 2.

[0045] The liquid-cooled main unit of this magnetic stimulation therapy device adds water to the water tank 2 through an additional water supply and drainage pipe connected to the water tank 2. Compared with the existing technology where water is added to the sight tube 3 through the vent 31 above the sight tube 3 and the water in the sight tube 3 flows into the water tank 2 through the inlet and outlet 33 at the bottom, the water supply method does not block the vent 32 of the sight tube 3 during the water supply process. The air inside the water tank 2 is less likely to form a high-pressure environment, and there is no problem of difficulty in adding water to the water tank 2, which makes it easier to increase the water supply speed of the water tank 2.

[0046] like Figure 1 and Figure 2 As shown, in some embodiments, the water supply and drainage pipes include partially or entirely flexible pipe bodies 51, which can be made of PP material. A through hole is provided on the side wall of the main housing 1, and one end of the flexible pipe body 51 passes through the through hole of the main housing 1 and communicates with the water tank 2; the port of the flexible pipe body 51 located outside the main housing 1 is the water supply and drainage port. External water can enter the water tank 2 through the water supply and drainage ports of the flexible pipe body 51. Furthermore, a sealing plug 52 is detachably and sealingly connected to the water supply and drainage ports of the flexible pipe body 51, serving a sealing function. When water needs to be added or drained, the sealing plug 52 is removed from the water supply and drainage ports of the flexible pipe body 51; after water is added, the sealing plug 52 is sealed back onto the water supply and drainage ports of the flexible pipe body 51.

[0047] like Figure 1 and Figure 2As shown, in some embodiments, the flexible tube 51 includes a first tube segment 511 located inside the main housing 1 and a second tube segment 512 located outside the main housing 1. The fill and drain ports are located on the second tube segment 512, which is detachably connected to the outer wall of the main housing 1 by a fastener 53. The second tube segment 512 has a first state where it is fixed to the main housing 1 by the fastener 53, and a second state where it is released from the main housing 1. When the water tank 2 needs to be filled with water, the fastener 53 is used to fix the second tube segment 512 to the side wall of the main housing 1. At this time, the height of the fill and drain port is usually higher than the height of the vent 32, and the port of the second tube segment 512 is set upwards. External water can enter the water tank 2 through the fill and drain ports, which can avoid the problem of difficulty in filling water caused by the vent 32, and the water filling speed is faster. When it is necessary to drain the water in water tank 2, remove the fixing piece 53 to contact the fixing of the second pipe section 512 to the main unit housing 1. Since the second pipe section 512 is relatively flexible, it will lie flat after being unfixed. At this time, the inlet and outlet of the water tank will be lower than the bottom of the water tank 2, and the water in the water tank 2 can be drained out through the inlet and outlet, making it convenient for the water in the water tank 2 to be drained out through the flexible pipe. Using the flexible pipe 51 as the water tank 2 can not only add water to the water tank 2, but also drain water from the water tank 2, realizing the combination of water inlet and outlet, making it more convenient for users to operate.

[0048] like Figure 2 As shown, in some embodiments, the height of the second connecting pipe 42 is lower than the height of the first connecting pipe 41. The second connecting pipe 42 is used to keep the liquid level in the water tank 2 and the sight glass 3 consistent. The second connecting pipe 42 and the first section 511 of the flexible pipe body converge inside the main housing 1 and are connected to the water tank 2 via an adapter. The height of the first section 511 of the flexible pipe body is lower than the height of the second connecting pipe 42 to ensure that water in the water tank 2 flows out through the flexible pipe body during drainage.

[0049] like Figure 4 and Figure 7 As shown, in some embodiments, the vent 31 at the top of the sight tube 3 can also be used to add water. The vent 31 and the flexible tube of the sight tube 3 work together to add water to the water tank 2, which can further improve the water adding efficiency of the water tank 2.

[0050] like Figure 1 and Figure 7As shown, in some embodiments, the water supply and drainage pipelines also include a water supply auxiliary pipeline 6. The lower end of the water supply auxiliary pipeline 6 is located inside the sight tube 3, and the lower opening of the water supply auxiliary pipeline 6 is directly connected to the inlet and outlet 33 of the sight tube 3. The upper opening of the water supply auxiliary pipeline 6 is located outside the sight tube 3. When the water tank 2 needs to be filled with water, external water can directly enter the inlet and outlet 33 of the sight tube 3 and the second connecting pipeline 42 through the water supply auxiliary pipeline 6, thereby avoiding the blockage of the vent 32 at the top of the sight tube 3 during water filling, which would otherwise cause difficulty in filling water. The upper opening of the water supply auxiliary pipeline 6 is connected to a conical cylinder 7 with a large upper opening and a small lower opening. The water supply auxiliary pipeline 6 can be a specially designed funnel. The outlet end of the water supply auxiliary pipeline 6 extends into the sight tube 3 and is directly connected to the inlet and outlet 33.

[0051] like Figure 1 and Figure 7 As shown, in some embodiments, the liquid cooling unit also includes a protective cover 9, which covers the outer periphery of the sight glass 3 and the flexible tube, and is used to protect the sight glass 3 and the flexible tube. The protective cover 9 is formed by stamping and bending sheet metal, and has a window in the middle that exposes the sight glass 34 and the water level scale thereon, so that the user can observe the water level at any time. The protective cover 9 is fixed to the main unit housing 1 with screws, and the protective cover 9 needs to be removed when adding or draining water.

[0052] In some embodiments, the sight glass 3 is provided with inlet and outlet ports 33, and a second connecting pipe 42 connects the inlet and outlet ports 33 and the water tank 2. The height of the inlet and outlet ports 33 is lower than the height of the vent port 32, and the height of the second connecting pipe 42 is lower than the height of the first connecting pipe 41. The water supply and drainage pipes include a water supply auxiliary pipe 6, one end of which extends into the sight glass 3 from the vent port 31. The lower opening of the water supply auxiliary pipe 6 is connected to the inlet and outlet ports 33, and the upper opening of the water supply auxiliary pipe 6 is located outside the sight glass 3. The upper opening of the water supply auxiliary pipe 6 is the water supply and drainage port. During the water supply process, water directly enters the water tank 2 through the water supply auxiliary pipe 6, the inlet and outlet ports 33 of the sight glass 3, and the second connecting pipe 42. Water is not directly added into the interior of the sight glass 3, thus avoiding the problem of clogging the vent port 32 at the top of the sight glass 3 during the water supply process, which helps to improve the water supply speed of the water tank 2. When the water in the water tank 2 is filled to the set height, the water in the water tank 2 will flow to the sight tube 3 through the first connecting pipe 41, so that the water level in the water tank 2 can be determined according to the liquid level in the sight tube 3.

[0053] This application also provides a magnetic stimulation therapy device, including a stimulation host; a stimulation coil assembly connected to the stimulation host for performing magnetic stimulation therapy on a target area of ​​a patient; and a liquid-cooled host of the magnetic stimulation therapy device as described above, connected to the stimulation coil assembly for cooling the stimulation coil assembly.

[0054] In summary, the liquid-cooled main unit of the magnetic stimulation therapy device provided in this application embodiment, by additionally setting up a water supply and drainage pipe connected to the water tank 2, allows water to be added to the water tank 2 through the water supply and drainage pipe. During the water addition process, the vent 32 at the top of the sight tube 3 is not blocked, resulting in a faster water addition speed for the water tank 2. Furthermore, the water level in the water tank 2 can be observed using the sight tube 3 to determine if it has reached the set height, thus improving the water addition speed. Compared to the prior art method of adding water to the sight tube 3 through the vent 31 at the top of the sight tube 3, and the water in the sight tube 3 flowing into the water tank 2 through the inlet and outlet 33 at the bottom, this method avoids blocking the vent 32 of the sight tube 3 during water addition, prevents the formation of a high-pressure environment inside the water tank 2, and eliminates the problem of difficulty in adding water to the water tank 2, thereby facilitating a faster water addition speed. In addition, water is added and drained through the flexible pipe 51, which allows users to adjust the working angle of the flexible pipe 51, thus facilitating water addition and drainage; the water inlet and outlet are combined, making it more convenient for users to operate.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
