Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot compress therapy and massage equipment, and in particular to a hot compress salt therapy device. Background Technology
[0002] The core principle of hot compress salt therapy devices is to utilize the heat and far-infrared radiation released by heated salt to provide heat therapy to the body. Sea salt is rich in various minerals and trace elements, and has the characteristic of not cooling down easily once heated, making it very effective in anti-inflammatory, analgesic, and balance-regulating effects. During the heating process, these components penetrate deep into the skin along with the heat, promoting local blood circulation, accelerating metabolism, relieving muscle tension and pain, and improving sleep quality. Hot compress salt therapy devices come in various types, and can be categorized by heating method, such as electric heating and microwave heating types.
[0003] Existing hot compress salt therapy devices are usually electrically heated, which heat the salt pack by setting a heating wire. The heated salt pack is then applied to the area of the body that needs heat. However, when heating the salt pack, the use of a heating wire can easily lead to overheating, which can cause safety issues such as burns or even spontaneous combustion. Utility Model Content
[0004] This invention addresses the safety issues of current hot compress salt therapy institutions lacking overheat protection, which leads to overheating, easy burns to users, and the risk of overheating and combustion. It proposes a hot compress salt therapy device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A hot compress salt therapy device includes a hot compress salt bag and a control system. The hot compress salt bag includes a therapy layer and a heating layer. The control system includes a heating module and an overheat protection module. The heating module is connected to the heating layer to control the heating of the therapy layer by the heating layer. The overheat protection module is connected to the heating module to disconnect the heating when the heating layer reaches a predetermined temperature. The overheat protection module includes a first overheat protection module and a second overheat protection module. The first overheat protection module is connected to the heating layer, and the second overheat protection module is connected to the heating module. This device connects the overheat protection module to the heating module. The overheat protection module detects the corresponding temperature data. When the heating module heats the hot compress salt bag to the predetermined temperature, the overheat protection module immediately disconnects the heating module from the heating layer to stop the heating of the heating layer, effectively preventing overheating. Furthermore, the overheat protection module includes a first overheat protection module connected to the heating layer and a second overheat protection module connected to the heating module, further improving safety through dual overheat protection.
[0007] Furthermore, the first over-temperature protection module includes a first temperature sensor and a first short-circuit protector. The first temperature sensor is used to monitor at least the temperature of the heating layer. The second over-temperature protection module includes a power monitor and a second short-circuit protector. The power monitor is used to monitor at least the output power of the heating module. This device improves the accuracy of temperature monitoring and further enhances the efficiency of over-temperature protection by monitoring both temperature and power data.
[0008] Furthermore, the control system includes an output terminal that connects to the heating module, and the heating layer includes an input terminal. The output terminal and the input terminal are detachably connected to achieve the connection between the heating module and the heating layer. This device, by designing the control system and the hot compress salt bag as separate components, allows them to be separated when not in use, preventing continuous heating of the heating layer and improving safety. In addition, the separate structure also enhances the device's versatility.
[0009] Furthermore, the output cable end includes a first latch, and the input cable end includes a second latch, which engage with each other. This device improves the connection strength between the output cable ends by using the interlocking of the first and second latches, preventing the control system and the hot compress salt bag from easily detaching during use.
[0010] Furthermore, the control system includes a controller housing, a power supply module, and a control motherboard. The control motherboard houses a control module, and both the heating module and the over-temperature protection module are connected to the control module. Both the heating module and the second over-temperature protection module are mounted on the control motherboard, which is housed within the controller housing. The power supply module is connected to the control module. This device optimizes the circuit layout and reduces connection points between components by integrating the heating module, the second over-temperature protection module, and the control module onto the control motherboard, greatly simplifying the installation process and facilitating mass production. The control module further enhances program execution capabilities and improves heat therapy efficiency. Furthermore, housing the control motherboard within the controller housing provides additional protection and simplifies user operation.
[0011] Furthermore, the control motherboard includes a temperature adjustment module and a heating time control module, both of which are connected to the control module. The controller housing has temperature adjustment buttons and heating time control buttons; the temperature adjustment buttons are connected to the temperature adjustment module, and the heating time control buttons are connected to the heating time control module. This device allows for adjustment of the heating temperature via the temperature adjustment module and the heating time via the heating time control module, further enhancing the therapeutic effect of heat therapy.
[0012] Furthermore, the control motherboard includes a locking module connected to the control module to lock the temperature adjustment module and the heating time control module. The controller housing has a locking button connected to the locking module. This device, by incorporating the locking module, can temporarily lock the operation of the temperature adjustment module and the heating time control module to prevent accidental button presses by the user, which could disrupt normal heat therapy.
[0013] Furthermore, the control motherboard includes a display module, which is connected to both the control module and the power supply module. This device uses the display module to show relevant information, improving user convenience.
[0014] Furthermore, the power module includes a power control module and a power cord. The power control module is connected to the control module, one end of the power cord is connected to the power control module, and the other end of the power cord is connected to an external power source. The controller box has a power switch button, which is connected to the power control module. This device can be connected to a household 220V power supply via the power cord, greatly improving the heating speed of the heating layer on the therapy layer and increasing heating efficiency.
[0015] Furthermore, the hot compress salt bag includes an insulation layer and a skin-friendly layer. The insulation layer is positioned between the heating layer and the therapeutic layer, while the therapeutic layer is positioned between the skin-friendly layer and the insulation layer. The heating layer includes a bottom layer and a heating wire assembly, with the heating wire assembly evenly distributed on the bottom layer. The heating wire assembly includes heating wires and an insulating sleeve fitted over the heating wires. By placing the therapeutic layer between the insulation layer and the heating layer, this device avoids direct contact between the therapeutic layer and the heating layer. Heat is transferred to the therapeutic layer through the insulation layer, resulting in more uniform heating of the therapeutic layer and reducing heat loss from the heating layer. The insulating sleeve on the heating wire further enhances safety.
[0016] Furthermore, the treatment layer includes multiple salt packs, which are evenly distributed in a grid pattern. By arranging the salt packs in a grid pattern, this device facilitates heating and ensures more even heating of the salt packs. Simultaneously, the grid design allows the medication within the salt packs to fully contact the air, resulting in a more even release of heat during heating and enhancing the therapeutic effect.
[0017] Furthermore, the insulation layer is equipped with a temperature sensing module, which is connected to the control module. The control mainboard has a temperature alarm module, which is connected to both the temperature sensing module and the control module. By installing a temperature sensing module on the insulation layer and monitoring its temperature, and connecting it to the temperature alarm module, this device allows users to clearly understand the current heating temperature, improving ease of use and safety.
[0018] Furthermore, the device includes at least four hot compress salt bags of different shapes. By using hot compress salt bags of different shapes, the device can be adapted to hot compress therapy on different body parts, thus further improving its applicability.
[0019] As can be seen from the above technical solutions, the advantages of this utility model are:
[0020] 1. This device connects an over-temperature protection module to the heating module. When the heating module heats the hot compress salt bag to the predetermined temperature, the over-temperature protection module immediately disconnects the heating module from the heating layer to stop the heating of the heating layer, effectively avoiding overheating. In addition, the dual over-temperature protection further improves the safety of use.
[0021] 2. This device improves the accuracy of temperature monitoring by monitoring both temperature and electrical power, thereby further enhancing the efficiency of over-temperature protection. Attached Figure Description

[0029] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0030] Please see Figures 1-4 A hot compress salt therapy device includes a hot compress salt bag body 100 and a control system 200. The hot compress salt bag body 100 includes a therapy layer 110 and a heating layer 120. The control system 200 includes a heating module 210 and an over-temperature protection module. The heating module 210 is connected to the heating layer 120 to control the heating layer 120 to heat the therapy layer 110. The over-temperature protection module is connected to the heating module 210 to disconnect the heating when the heating layer 120 reaches a predetermined temperature. The over-temperature protection module includes a first over-temperature protection module 221 and a second over-temperature protection module 222. The first over-temperature protection module 221 is connected to the heating layer 120, and the second over-temperature protection module 222 is connected to the heating module 210.
[0031] In this embodiment, a mixture of medicines such as hot compress salts is disposed inside the physiotherapy layer 110. The heating layer 120 is close to the physiotherapy layer 110, and the control system 200 is connected to the heating layer 120. By outputting electricity to the heating layer 120, the heating layer 120 generates heat and heats the physiotherapy layer 110. In use, the physiotherapy layer 110 is first fixed to the area that needs hot compress, and then the heating module 210 is used to control the heating layer 120 to heat the physiotherapy layer 110, so that the mixture of medicines such as hot compress salts in the physiotherapy layer 110 can be fully released to the area to be heated. In addition, an over-temperature protection module is connected to the heating module 210. When the heating layer 120 heats the therapy layer 110 to the set temperature, for example, when the temperature reaches 60°C, the over-temperature protection module will disconnect the connection between the heating module 210 and the heating layer 120, thereby stopping the heating layer 120 from heating. The over-temperature protection module includes a first over-temperature protection module 221 and a second over-temperature protection module 222. The first over-temperature protection module 221 is located inside the hot compress salt bag 100 and connected to the heating layer 120, monitoring the temperature-related data on the heating layer 120. The second over-temperature protection module 222 is located inside the control system 200 and connected to the heating module 210, monitoring the temperature-related data on the heating module 210. The data from the first and second over-temperature modules are analyzed respectively. If either data reaches the threshold, the connection between the heating module 210 and the heating layer 120 will be disconnected, achieving the function of dual over-temperature protection.
[0032] In the above structure, the over-temperature protection module monitors the corresponding temperature data and can disconnect the heating module 210 from the heating layer 120 after the set temperature is reached, so as to stop the heating operation of the heating layer 120 and effectively avoid overheating. In addition, by connecting the first over-temperature protection module 221 to the heating layer 120 and the second over-temperature protection module 222 to the heating module 210, dual over-temperature protection is achieved, further improving the safety of use.
[0033] More specifically, the first over-temperature protection module 221 includes a first temperature sensor and a first short-circuit protector. The first temperature sensor is used to monitor the temperature of the heating layer 120 at least. The second over-temperature protection module 222 includes an electrical power monitor and a second short-circuit protector. The electrical power monitor is used to monitor the output power of the heating module 210 at least.
[0034] In this embodiment, the first over-temperature module monitors the real-time temperature of the heating layer 120 and determines whether the threshold has been reached by directly feeding back the temperature data of the heating layer 120. The second over-temperature module monitors the electrical power data output by the heating module 210 to the heating layer 120 to determine whether the threshold has been reached, providing dual protection. During use, it can be ensured that if one fails, the other can continue to be used. Furthermore, by monitoring both temperature and electrical power values to determine whether over-temperature has occurred, the accuracy of over-temperature judgment is improved, thus enhancing the accuracy and efficiency of over-temperature protection.
[0035] In the specific structure connecting the control system 200 and the hot compress salt bag 100, the control system 200 includes an output line terminal 230, which is connected to the heating module 210. The heating layer 120 includes an input line terminal 150, and the output line terminal 230 and the input line terminal 150 are detachably connected to achieve the connection between the heating module 210 and the heating layer 120. The output line terminal 230 includes a first latch 231, and the input line terminal 150 includes a second latch. The first latch 231 and the second latch cooperate to engage.
[0036] In this embodiment, the control system 200 and the hot compress salt bag 100 are separate structures. The heating layer 120 is connected to an input line 150, which extends beyond the hot compress salt bag 100. The control system 200 is connected to an output line 230, which extends beyond the control system 200. In use, the output line 230 and the input line 150 are connected to form a passage. Furthermore, a first latch 231 is provided on the output line 230, and a second latch is provided on the input line 150. When the output line 230 and the input line 150 are connected, the first latch 231 and the second latch engage with each other. The first latch 231 can be an elastic locking block structure, and the second latch is a corresponding slot structure. The connection strength between the output line terminal 230 and the input line terminal 150 is improved by the interlocking of the first and second clips, which avoids the problem of accidentally tearing the connection between the output line terminal 230 and the input line terminal 150 during use, thus affecting normal use.
[0037] In the above structure, the control system 200 and the hot compress salt bag 100 are set as separate structures, which can be separated when not in use, avoiding the heating module 210 from continuously heating the heating layer 120, thereby improving the safety performance. In addition, the separate structure also improves the applicability of the device.
[0038] In the specific structure of the control system 200, the control system 200 includes a controller housing, a power supply module 240, and a control motherboard 250. The control motherboard 250 is equipped with a control module 260. The heating module 210 and the over-temperature protection module are both connected to the control module 260. The heating module 210 and the second over-temperature protection module 222 are both mounted on the control motherboard 250. The control motherboard 250 is housed within the controller housing, and the power supply module 240 is connected to the control module 260. The control motherboard 250 includes a temperature adjustment module 271 and a heating time control module 272, both of which are connected to the control module 260. The controller housing is equipped with a temperature adjustment button 320 and a heating time control button 330. The temperature adjustment button 320 is connected to the temperature adjustment module 271, and the heating time control button 330 is connected to the heating time control module 272. The control motherboard 250 includes a locking module 280, which is connected to the control module 260 to lock the temperature adjustment module 271 and the heating time control module 272. The controller housing has a locking button 340, which is connected to the locking module 280. The control motherboard 250 also includes a display module 290, which is connected to both the control module 260 and the power module 240. The power module 240 includes a power control module 241 and a power cord 242. The power control module 241 is connected to the control module 260, one end of the power cord 242 is connected to the power control module 241, and the other end is connected to an external power source. The controller housing has a power switch button 310, which is connected to the power control module 241.
[0039] In this embodiment, the control system 200 includes a control box 300, which is a hollow structure. The control motherboard 250 is installed inside the control box 300, and the shape of the control motherboard 250 is consistent with the shape of the control box 300. A control module 260 is provided on the control motherboard 250. The control module 260 is a single-chip microcomputer structure. The heating module 210 and the second over-temperature protection module are also provided on the control motherboard 250. The control module 260 integrates the operation of the heating module 210 and the second over-temperature protection module. By placing the heating module 210, the second over-temperature protection module 222 and the control module 260 together on the control motherboard 250, the circuit layout is optimized, the connection points between components are reduced, the installation process is greatly simplified, and it is convenient for mass production. The setting of the control module 260 further improves the program running capability and the heat therapy efficiency. By placing the control motherboard 250 inside the controller box, the control motherboard 250 can be further protected, and it is also convenient for users to operate.
[0040] In addition, the control motherboard 250 is equipped with a temperature adjustment module 271 and a heating time control module 272, both of which are connected to the control module 260. The temperature adjustment module 271 can control the output power of the heating module 210 to the heating layer 120, thereby controlling the heating temperature of the physiotherapy layer 110 by the heating layer 120. For example, the temperature adjustment module 271 can be adjusted to three levels: 40℃, 48℃, and 57℃. The heating time control module 272 can control the heating time, which can be the optimal heating time predetermined based on the medication in the physiotherapy layer 110, or the heating time can be adjusted manually. Correspondingly, a temperature adjustment button 320 and a heating time control button 330 are provided on the upper surface of the control box 300. These buttons are membrane buttons, with the temperature adjustment button 320 connected to the temperature adjustment module 271 and the heating time control button 330 connected to the heating time control module 272, allowing users to adjust them manually. The buttons are marked with corresponding text for easy identification. The device adjusts the heating temperature through the temperature regulation module 271 and the heating time through the heating time control module 272, thereby further improving the effect of hot compress therapy.
[0041] In addition, a locking module 280 is also provided on the control motherboard 250. The locking module 280 can temporarily lock the operation of the temperature adjustment module 271 and the heating time control module 272. Correspondingly, a locking button 340 is also provided on the control box 300, which is connected to the locking module 280. During use, after setting the corresponding heating temperature and heating time, pressing the locking button 340 activates the locking module 280, thereby temporarily locking the operation of the temperature adjustment module 271 and the heating time control module 272 to prevent accidental button presses that could interfere with normal hot compress therapy.
[0042] The control motherboard 250 also includes a display module 290, which is connected to the control module 260 to display relevant data from the control module 260. This display module 290 can be an LCD screen, displaying information including timer settings, therapy temperature settings, and therapy status. Displaying this information through the display module 290 improves user convenience. Furthermore, a power cord 242 connects to an external power source to supply power to the power control module 241, thereby powering the entire control system 200. A power switch button 310 is also located on the control box 300, connected to the power control module 241 to control the power supply to the overall control system 200. The power cord 242 can be connected to a standard 220V household power supply, significantly increasing the heating speed of the heating layer 120 on the therapy layer 110 and improving heating efficiency.
[0043] In the specific structure of the hot compress salt bag body 100, the hot compress salt bag body 100 includes a heat insulation layer 130 and a skin-friendly layer 140. The heat insulation layer 130 is disposed between the heating layer 120 and the physiotherapy layer 110, and the physiotherapy layer 110 is disposed between the skin-friendly layer 140 and the heat insulation layer 130.

The heating wire assembly is evenly distributed on the bottom layer and includes a heating wire and an insulating sleeve sleeved on the heating wire. The physiotherapy layer 110 includes multiple salt packs 111, which are evenly distributed in a grid pattern.
[0044] In this embodiment, the therapeutic layer 110 is positioned between the insulation layer 130 and the heating layer 120 to prevent direct contact between the therapeutic layer 110 and the heating layer 120. Heat is transferred to the therapeutic layer 110 through the insulation layer 130, resulting in more uniform heating of the therapeutic layer 110 and reducing heat loss from the heating layer 120. The addition of an insulating sleeve on the heating wire further enhances safety. Furthermore, the skin-friendly layer 140 can be made of hemp or cotton. By arranging the salt packs 111 in a grid pattern, this device facilitates heating and ensures more even heating of the salt packs 111. The grid design also allows the medication within the salt packs 111 to fully contact the air, resulting in more even heat release and improved heat therapy effect.
[0045] In addition, the insulation layer 130 is equipped with a temperature sensing module 131, which is connected to the control module 260. The control main board 250 is equipped with a temperature alarm module, which is connected to the temperature sensing module 131 and the control module 260.
