[0001] The invention relates to the technical field of medical care, and in particular to a water circulation temperature control system applied to a micro-current magnetic therapy apparatus. Background Art

[0002] With the improvement of the quality of life, people pay more and more attention to their physical health, and use some physical therapy devices to improve body functions and maintain physical health. Among them, microcurrent magnetic therapy devices can improve the overall health of the human body and improve the quality of life by regulating the biomagnetic field and promoting blood circulation. This treatment method is non-invasive and will not cause serious side effects or harm to the human body. It is very safe and effective.

[0003] The therapeutic effect of microcurrent magnetic therapy devices is often affected by the temperature of the treatment area. When running for a long time or under high load, heat may be generated inside the microcurrent magnetic therapy device, which will affect the temperature of the treatment area and cause the treatment effect to deteriorate. However, the appropriate temperature can improve blood circulation and promote cell metabolism, thereby enhancing the treatment effect. Therefore, a water circulation temperature control system can be set up for the microcurrent magnetic therapy device to control the temperature of the treatment area inside the device within the target temperature range to ensure the stability and consistency of the treatment effect.

[0004] However, during the temperature control process, the water flow heat is easily lost due to the problem of water flow transmission distance, which eventually leads to inaccurate temperature in the treatment area.

[0044] Specifically, the present invention provides a water circulation temperature control system applied to a micro-current magnetic therapy device, comprising:

[0045] A control unit, used to heat / cool the circulating water in the water storage heating unit and the pretreatment unit through heating instructions / cooling instructions;

[0046] A water storage and heating unit, which is used to store circulating water and heat the circulating water according to a heating instruction, and separate part of the circulating water into a pre-treatment unit;

[0047] A cooling unit is connected to the circulating water output pipeline of the water storage and heating unit, and is used to cool the circulating water heated by the water storage and heating unit;

[0048] An action unit, which is connected to the cooling unit and the water storage and heating unit, is used to receive the circulating water after the cooling treatment in the cooling unit and exchange the temperature with the outside, and re-transport the circulating water after the action to the water storage and heating unit through a transmission pipeline, wherein the action unit includes at least two action ends, and a switch valve is correspondingly provided at the water inlet of a single action end;

[0049] The detection unit is respectively connected to the cooling unit, the transmission pipeline, and the action unit, and is used to detect the first temperature of the circulating water passing through the cooling unit, the temperatures at several positions of each action end, and the flow rate of the circulating water in the transmission pipeline;

[0050] A pretreatment unit, which is respectively connected to the water storage and heating unit, the transmission pipeline, and the control unit, and is used to partially separate the circulating water in the water storage and heating unit, determine whether to perform preheating / precooling treatment according to a preset switching temperature difference and the current circulating water temperature, and treat the circulating water to a set pretreatment temperature according to a heating instruction / cooling instruction of the control unit;

[0051] The coordination unit is connected to the detection unit and the action unit respectively, and is used to determine the second temperature of the circulating water reaching the coordination unit according to the first temperature, the flow rate and the pipe length of the transmission pipe between the coordination unit and the cooling unit, and to judge the heating / cooling treatment of the circulating water output by the cooling unit based on the second temperature and the target temperature of the action unit, and to determine the temperature uniformity of a single action end and the temperature difference between each action end according to the temperatures at several positions of each action end, and to adjust the circulating water flow rate of the circulating water delivered by the coordination unit to the action unit based on the comparison result of the temperature difference and the preset temperature difference.

[0052] It can be understood that the microcurrent magnetic therapy device includes multiple working modes, and the temperature of the active end 2 of the active unit is different in the corresponding working mode. Therefore, a pretreatment unit is set to separate part of the circulating water in the water storage and heating unit and put it into the pretreatment unit. The preheating / precooling treatment of the pretreatment unit is used to achieve timely response of the microcurrent magnetic therapy device after the working mode is switched.

[0053] It is understandable that during the transportation process of the circulating water after passing through the cooling unit, due to the influence of factors such as the pipeline transportation length and the circulating water flow rate, there will be a temperature difference after the circulating water is transported to the action end 2. Therefore, a coordination unit is set to perform temperature judgment processing on the circulating water again.

[0054] In implementation, the action unit includes at least two action ends 2. Preferably, the action unit includes two action ends 2, the action end 2 is cylindrical, the action end 2 is a copper pot, and the several positions are the center position of the upper surface of the copper pot, the center position of the lower surface, and three positions based on the average distribution of the side circumference. The two action ends 2 are used to perform magnetic therapy on the treatment object. The number of action ends 2 of the action unit 2, the shape of the action end 2, the material of the action end 2, and the several positions of the action end 2 can be determined according to actual conditions and will not be repeated here.

[0055] In implementation, the preset switching temperature difference is in the range of 8°C to 14°C, preferably, the preset switching temperature difference is 10°C; the preset temperature difference is in the range of 2% to 5%, preferably, the preset temperature difference is 3%. The preset switching temperature difference, the range of values ​​and the preferred value of the preset temperature difference can be determined according to actual conditions, and will not be described in detail here.

[0056] The present invention realizes precise control of circulating water temperature, flow rate and temperature uniformity of the active end 2 through integrated pretreatment, detection, coordination and control units. The system response speed is improved through preheating / precooling treatment of the pretreatment unit; the detection unit monitors key parameters in real time to ensure data accuracy; the coordination unit dynamically adjusts the circulating water flow rate and temperature according to real-time data to ensure that the temperature of each active end 2 is uniform and the difference is within a preset range, avoiding water flow heat loss caused by water flow transmission distance problems, and avoiding the temperature of the treatment area being unable to respond quickly due to the switching of working modes during the treatment of the current magnetic therapy device, and quickly and effectively controlling the temperature of the treatment area within the target temperature range, improving the temperature accuracy of the treatment area, and ensuring the stability and consistency of the treatment effect.

[0057] Specifically, the water storage and heating unit is provided with a first water outlet and a second water outlet, the first water outlet is fixedly connected to the transmission pipeline, and the second water outlet is fixedly connected to the pretreatment unit;

[0058] Wherein, a first valve is arranged at the first water outlet, and a second valve is arranged at the second water outlet.

[0059] Specifically, the pretreatment unit is used to determine the amount of circulating water for pretreatment according to a preset water level.

[0060] Specifically, before starting the work, the first valve is closed, the second valve is opened, and part of the circulating water in the water storage and heating unit flows into the pretreatment unit through the second water outlet;

[0061] Wherein, a water level gauge is arranged on the inner wall of the pretreatment unit to monitor the water level of circulating water in the pretreatment unit.

[0062] It can be understood that before the normal working mode starts, part of the circulating water in the water storage and heating unit is separated into the pretreatment unit. In a certain working mode, the first valve is opened and the second valve is closed, and the circulating water enters the transmission pipeline from the first water outlet. At the same time, the circulating water in the pretreatment unit is preheated / precooled. Before starting work, the first valve is closed and the second valve is opened. The circulating water in the pretreatment unit enters the transmission pipeline for transmission first, so as to improve the flexibility and response speed of temperature switching.

[0063] In a specific embodiment, the water level meter is used to monitor the water level of the circulating water in the pretreatment unit. When the circulating water level reaches the preset water level, the second valve is closed and the first valve is opened. The preset water level value range is 80% to 95% of the height of the pretreatment unit. Preferably, the preset water level is 90% of the pretreatment unit. The preset water level value range and preferred value can be determined according to actual conditions and will not be described in detail here.

[0064] The present invention is provided with a first water outlet having a first valve and a second water outlet having a second valve, so as to realize flexible control of the flow direction of circulating water. The first water outlet is fixedly connected to the transmission pipeline and the water storage and heating unit to ensure smooth circulation of circulating water in normal working mode; and the second water outlet is connected to the pretreatment unit to allow part of the circulating water to be preheated / precooled, thereby improving the flexibility and response speed of the system, thereby further improving the temperature accuracy of the treatment area and ensuring the stability and consistency of the treatment effect.

[0065] Specifically, the portion of the transmission pipeline close to the cooling unit is a spiral transmission pipe 3, which is used to control the flow rate of circulating water and adjust the temperature of circulating water;

[0066] The number of the spiral transmission tubes 3 corresponds to the number of the action ends 2 , and each spiral transmission tube 3 includes at least three annular spiral pipes.

[0067] It can be understood that by providing the spiral transmission tube 3, the contact area and time between the circulating water and the inner wall of the pipe can be increased, thereby reducing the temperature of the circulating water in advance by heat conduction and convection, and cooling the circulating water heated in the water storage heating unit in advance, so as to reduce the workload of the subsequent cooling unit, improve the working efficiency of the cooling unit, and optimize the system performance.

[0068] In practice, each spiral transmission pipe 3 includes at least three annular spiral pipes. Preferably, each spiral transmission pipe 3 includes three annular spiral pipes. A more complex flow path is formed by multiple annular spiral pipes, which increases the contact opportunity between the circulating water and the pipe wall, thereby more effectively reducing the water temperature of the circulating water. The number of annular spiral pipes and the diameter of the annular spiral pipes of the spiral transmission pipe 3 can be determined according to actual conditions, and will not be repeated here.

[0069] Specifically, the coordination unit determines the second temperature of the circulating water reaching the coordination unit, including: the coordination unit determines the temperature loss according to the first temperature, the flow rate, and the pipeline length, and determines the second temperature according to the temperature loss.

[0070] It can be understood that the temperature of the circulating water reaching the cooling unit through the transmission pipeline is the first temperature, and the temperature of the coordination unit will fluctuate. At this time, the circulating water temperature of the coordination unit is the second temperature. The pipeline length is the length of the transmission pipeline from the cooling unit to the coordination unit for the circulating water. The coordination unit can determine the temperature loss based on the first temperature, the flow rate, and the pipeline length, and determine the temperature (second temperature) of the circulating water in the coordination unit at this time based on the temperature loss.

[0071] The temperature loss calculation formula is as follows:

[0072] ΔT=α×L×(T ‘ -T e ) (1)

[0073] Among them, α is an empirical coefficient, which can be determined according to the surface roughness of the transmission pipeline, the flow rate of the circulating water in the transmission pipeline, and the cross-sectional diameter of the transmission pipeline. L is the length of the transmission pipeline from the cooling unit to the coordination unit for circulating water. T ‘ is the temperature of the circulating water after being treated by the cooling unit (first temperature), T e is the ambient temperature.

[0074] The second temperature T ‘’ The calculation formula is as follows:

[0075] T ‘’ =T ‘ -ΔT (2)

[0076] Among them, T ‘is the temperature of the circulating water after being processed by the cooling unit (first temperature), and ΔT is the temperature loss.

[0077] Specifically, the coordination unit determines to heat / cool the circulating water output by the cooling unit based on the second temperature and the target temperature of the action unit, including:

[0078] If the second temperature is lower than the target temperature, the coordination unit heats the circulating water to the target temperature;

[0079] If the second temperature is greater than the target temperature, the coordination unit cools the circulating water to the target temperature.

[0080] It is understandable that the coordination unit is set so that the coordination unit can intelligently adjust the temperature of the circulating water according to the second temperature (temperature after temperature loss is taken into account) when the circulating water reaches it and the target temperature required by the action unit. If the second temperature is lower than the target temperature, the coordination unit will automatically start the heating mechanism to heat the circulating water to the target temperature; on the contrary, if the second temperature is higher than the target temperature, the coordination unit will take cooling measures to cool the circulating water to the target temperature to ensure that the circulating water can be supplied to the action unit at a suitable temperature.

[0081] In implementation, the target temperature of the action unit may be determined according to a specific working mode, which is not specifically limited here and will not be described in detail.

[0082] Specifically, the coordination unit determines the temperature difference of each working end 2 according to the temperature uniformity of each working end 2 and the number of the working ends 2, and adjusts the circulating water flow rate of the circulating water delivered by the coordination unit to each working end 2 based on the comparison result of the temperature difference with the preset temperature difference and the temperature uniformity of each working end 2.

[0083] It can be understood that the temperature difference is the temperature difference of the circulating water delivered from the coordination unit to each action end 2. Based on this temperature difference, it can be determined whether the temperatures of several action ends 2 are within the preset temperature difference. The circulating water flow rate is adjusted according to the comparison result between the temperature difference and the preset temperature difference and the temperature uniformity. By controlling the circulating water flow rate, the temperature balance of the action end 2 is controlled to achieve better treatment effect.

[0084] The temperature uniformity T of the i-th active end 2 i The calculation formula is as follows:

[0085]

[0086] Among them, T ijis the temperature of the jth position of the i-th active end 2, i=1, 2, .., N, j=1, 2, ..., M, M is the number of positions of a single active end 2.

[0087] The temperature difference calculation formula of each active end 2 is as follows:

[0088]

[0089] Where N is the total number of active ends 2 in the active unit, is the average value of temperature uniformity of N active ends 2.

[0090] The circulating water flow rate V of the circulating water delivered by the coordination unit to the i-th action end 2 i The formula is as follows:

[0091] V i =(1+ΔV i )×V 0 (5)

[0092] Where, ΔV i is the adjustment factor of the i-th active end 2, which can be determined based on the difference between the temperature difference and the preset temperature difference, and the temperature uniformity of the i-th active end 2. When ΔV i is a negative number, reducing the circulating water flow rate to the i-th action end 2. When ΔV i is a positive number, increasing the circulating water flow rate to the i-th action end 2, V 0 is the initial flow rate of circulating water when it flows into the coordination unit, i=1, 2, .., N, N is the number of active ends 2.

[0093] Specifically, the detection unit detects the temperature of each position of each annular spiral pipe of the spiral transmission pipe 3 based on a preset detection range and transmits it to the control unit. The control unit constructs a spiral pipe temperature curve based on the temperature of each position, determines the degree of temperature mutation according to the spiral pipe temperature curve, and determines the heat loss rate of the inlet temperature and outlet temperature of the spiral transmission pipe 3 according to the degree of temperature mutation, compares the heat loss rate with the preset heat loss rate, and adjusts the initial heating temperature of the circulating water entering the spiral transmission pipe 3 from the water storage and heating unit according to the comparison result.

[0094] It is understandable that the temperature of the circulating water can be reduced to a certain extent through the spiral transmission tube 3, and then it is processed and transmitted to the action unit through the cooling unit. Therefore, the temperature of the circulating water after passing through the spiral transmission tube 3 should be moderately reduced but without excessive loss of heat energy. The preset detection range is several positions of a single annular spiral pipe. The detection unit is set to monitor the temperature of different positions of each annular spiral pipe in the spiral transmission tube 3. These data are used to construct a temperature curve, analyze the temperature mutation, and calculate the heat loss rate. Subsequently, according to the comparison result of the heat loss rate and the preset heat loss rate, the initial heating temperature of the circulating water entering the spiral transmission tube 3 from the water storage heating unit is automatically adjusted.

[0095] In implementation, preferably, the preset detection range has a value range of the top, bottom, left and right positions of a single annular spiral pipe, and the preset heat loss rate has a value range of 8% to 12%. Preferably, the preset heat loss rate is 10%. The preset detection range, the preset heat loss rate value range and the preferred value can be determined according to actual conditions and will not be repeated here.

[0096] Specifically, the control unit determines the temperature gradient based on the temperature curve of the spiral pipeline, determines the temperature mutation area according to the temperature gradient, and determines the degree of the temperature mutation based on the temperature gradient and the temperature mutation area.

[0097] It can be understood that the temperature gradient is the rate of change at several positions in different annular spiral pipes during the flow of circulating water. The temperature gradient changes steadily downward. When there is a temperature mutation area, it means that the annular spiral pipe may have abnormal conditions such as leakage or blockage. Therefore, the degree of temperature mutation is determined based on the temperature gradient and the temperature mutation area.

[0098] During the circulation of water, the temperatures at several positions in different annular spiral pipes constitute the spiral pipe temperature curve. The temperature gradient calculation formula between the n+1th position and the nth position is as follows:

[0099]

[0100] Among them, T n+1 is the temperature at the n+1th position, T n is the temperature at the nth position, Δx is the length of the transmission pipeline between the n+1th position and the nth position, n=1,2,..,N 1 -1,N 1 is the total number of positions in different annular spiral pipes.

[0101] The calculation formula for the degree of temperature mutation is as follows:

[0102]

[0103] Among them, x m is the mth mutation region, m = 1, 2, ...M 1 , M 1 is the number of mutation regions.

[0104] The heat loss rate calculation formula is as follows:

[0105]

[0106] Among them, T in is the circulating water temperature at the inlet of spiral transmission pipe 3, T out It is the circulating water temperature at the outlet of spiral transmission pipe 3.

[0107] Specifically, the detection unit adjusts the initial heating temperature of the circulating water entering the spiral transmission pipe 3 from the water storage and heating unit according to the comparison result, including:

[0108] If the heat loss rate is greater than the preset heat loss rate, increasing the initial heating temperature of the water storage heating unit;

[0109] If the heat loss rate is less than the preset heat loss rate, the initial heating temperature of the water storage heating unit is reduced.

[0110] It can be understood that the initial heating temperature can be determined according to the temperature required for each working mode, because the circulating water in the water storage and heating unit must pass through the pretreatment unit, the transmission pipeline, the cooling unit, and the coordination unit before finally reaching the action unit. Therefore, in implementation, the initial heating temperature can be comprehensively determined based on the action unit temperature required for each working mode. Preferably, the initial heating temperature is the average value of the action end temperature required for each working mode. The initial heating temperature can be determined based on actual conditions and will not be repeated here.

[0111] The present invention is provided with a spiral transmission tube 3, which effectively controls the flow rate of circulating water through its unique spiral structure, and naturally reduces the temperature of circulating water, thereby reducing energy consumption. At the same time, the detection unit accurately monitors the temperature of each position of the spiral pipeline, and combines the construction of the temperature curve, so that the system can accurately identify and respond to temperature mutations, allowing the circulating water passing through the spiral transmission tube 3 to cool to a certain range, but not excessively, further ensuring the efficient operation of the system, improving the temperature accuracy of the treatment area, and ensuring the stability and consistency of the treatment effect.
