[0002] Hot and cold compress therapy is a common treatment method in post-medical aesthetic care and sports rehabilitation.

To avoid the risk of cross-infection, the hot and cold compress compress bags are designed as individual consumables, connected to the main unit via a connector. When using the hot and cold compress therapy equipment, simply tighten the connector, and the main unit will then start the circulation pump and temperature control system.

[0062] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0063] As described in the background section, hot and cold compress therapy is a common treatment method in post-medical aesthetic care and sports rehabilitation. The compress bag, as a core consumable in the therapy equipment that comes into direct contact with the human body, directly affects the safety and therapeutic effect due to its structure and connection method. To avoid the risk of cross-infection, the hot and cold compress bags are designed as individual consumables, connected to the main unit via a connector. When using the hot and cold compress therapy equipment, simply tighten the connector, and the main unit will then activate the circulation pump and temperature control system. However, the current accuracy of the connector tightening recognition is poor, frequently resulting in misjudgments and causing the main unit to start erroneously.

[0064] Based on this, the present disclosure provides a connection control method, a connector structure, and a detachable hot and cold compress therapy device, which improves the identification accuracy of connection locking between the plug and the connector, and improves the situation of connection locking misjudgment and device erroneous start.

[0065] On one hand, this disclosure provides a connection control method applied to a detachable hot and cold compress therapy device. (Reference) Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of a connector structure provided in an embodiment of the present disclosure. Figure 2 This is a flowchart illustrating a connection control method provided in an embodiment of this disclosure. The detachable hot and cold compress therapy device provided in this embodiment includes a hot and cold compress bag, a main unit, and a connector structure. The connector structure includes a plug 100 and a connector 200. The plug 100 can be connected to the hot and cold compress bag, while the connector 200 can be connected to the main unit. The hot and cold compress bag includes, but is not limited to, bags for use on parts of the human body, such as the arms, legs, head, and waist.

[0066] A magnetic element 110 is provided in the plug 100, and the magnetic element 110 may be, but is not limited to, embedded in the housing portion of the plug 100 for fixation. A connector 200 is matched with the plug 100 for insertion and removal. The connector 200 is provided with a magnetic induction element 210, and the magnetic induction element 210 may be, but is not limited to, embedded in the housing portion of the connector 200 for fixation. In one embodiment, the plug 100 provided in this embodiment has a post, and the connector 200 has a socket that matches the insertion portion; in another embodiment, the plug 100 provided in this embodiment has a socket, and the connector 200 has a post that matches the socket. During the insertion and removal process of the plug 100 and the connector 200, the first state is when the magnetic induction element 210 senses that the distance between itself and the magnetic element 110 is not greater than a locking distance threshold. The locking distance threshold is the maximum distance that can be achieved between the magnetic element 110 and the magnetic induction element 210 when the connection between the plug 100 and the connector 200 is locked.

[0067] Based on this, the connection control method provided in this disclosure includes:

[0068] S1, the magnetic induction element 210 senses the distance between itself and the magnetic element 110.

[0069] S21. Determine whether the first state continues for a set duration. If yes, output the first control signal; otherwise, maintain the output of the second control signal. The first control signal is used to control the detachable hot and cold compress therapy device to start working, and the second control signal is used to control the detachable hot and cold compress therapy device to stop working. That is, the first control signal controls the main unit of the detachable hot and cold compress therapy device to start the circulation pump and temperature control system, etc., to transfer cold or hot energy to the hot and cold compress bag to start the therapy; while the second control signal controls the main unit to stop the circulation pump and temperature control system, etc., so that the main unit is in standby or shutdown state.

[0070] The connection control method provided in this embodiment first determines the distance between the magnetic induction element 210 and the magnetic element 110 during the insertion and removal process of the plug 100 and the connector 200. When the magnetic induction element 210 senses that the distance between it and the magnetic element 110 is not greater than the locking distance threshold, it is initially determined that the connection between the plug 100 and the connector 200 is locked. At this time, the magnetic induction element 210 is in a first state. Then, it determines the duration of the magnetic induction element 210 being in the first state. When the first state is maintained for a set duration, it is finally determined that the connection between the plug 100 and the connector 200 is locked. This improves the recognition accuracy of the connection locking between the plug 100 and the connector 200, thereby improving the situation of misjudgment and equipment erroneous start-up. For example, in scenarios such as when a user abandons inserting plug 100 into connector 200, or when a user accidentally inserts plug 100 into connector 200 and quickly pulls it out after locking the connection, or when plug 100 springs back after being inserted into connector 200, although the user inserts plug 100 into connector 200 such that the distance between magnetic sensing element 210 and magnetic element 110 is no greater than the locking distance threshold, and magnetic sensing element 210 successfully senses that the distance between it and magnetic element 110 is no greater than the locking distance threshold and is in the first state; however, the first state of magnetic sensing element 210 does not meet the condition of continuous setting time, thus enabling identification and determination that the connection between plug 100 and connector 200 is only a loose connection and not a final locked connection. This improves the situation where the connection between plug 100 and connector 200 is mistakenly judged as a locked connection due to a loose connection, and avoids the problem of the host device starting up due to a misjudgment of a loose connection.

[0071] In some embodiments, the set duration provided in this disclosure can be in the range of 50-100ms, such as 60ms, 70ms, 80ms, 90ms, etc.

[0072] In some embodiments, the connection control method provided in this disclosure can also solve the problem that when the connection between the plug 100 and the connector 200 is locked, the user's misoperation may be identified as a disconnection, causing the host device to stop working. See details. Figure 3 As shown, during the insertion and removal of plug 100 and connector 200, the magnetic induction element 210 is in the second state when it senses that the distance between it and magnetic element 110 is greater than the locking distance threshold.

[0073] Based on this, the connection control method provided in this disclosure includes:

[0074] S22. Determine whether the second state lasts for a set duration. If yes, output the second control signal; otherwise, maintain the output of the first control signal. First, determine the distance between the magnetic induction element 210 and the magnetic element 110. When the magnetic induction element 210 senses that the distance between it and the magnetic element 110 is greater than the locking distance threshold, it is initially determined that the connection between the plug 100 and the connector 200 is broken. At this time, the magnetic induction element 210 is in the second state. Then, determine the duration of the magnetic induction element 210 being in the second state. If the second state is maintained for a set duration, it is finally determined that the connection between the plug 100 and the connector 200 is broken. If the duration of the second state does not reach the set duration, it is finally determined that the connection between the plug 100 and the connector 200 remains locked. This improves the recognition accuracy of the connection break between the plug 100 and the connector 200, thereby improving the situation of false judgment and equipment accidental stoppage. For example, when the connection between plug 100 and connector 200 is locked, during the operation of the main equipment, if the user accidentally pulls the plug 100 and connector 200 apart by a certain distance without disconnecting them, and then instantly restores the connection between plug 100 and connector 200 to the locked state, the magnetic induction element 210, although sensing that the distance between it and the magnetic element 110 is greater than the locking distance threshold and is in the second state, does not meet the condition of continuous setting time due to the instantaneous accidental operation. Therefore, it can be identified that the connection between plug 100 and connector 200 is not finally disconnected, thereby improving the identification accuracy of the connection disconnection between plug 100 and connector 200 and improving the situation of misjudgment and equipment accidental stoppage.

[0075] In some embodiments, the state of the magnetic sensing element 210 provided in this disclosure can be converted into a voltage for determination. For example, determining whether the first state continues for a set duration according to this disclosure includes: generating a first voltage based on the first state; determining whether the first voltage continues for a set duration; if yes, outputting a first control signal; if no, maintaining the output of a second control signal. Alternatively, determining whether the second state continues for a set duration according to this disclosure includes: generating a second voltage based on the second state; determining whether the second voltage continues for a set duration; if yes, outputting a second control signal; if no, maintaining the output of the first control signal.

[0076] In some embodiments, the voltage analysis and judgment process provided by this disclosure can convert the voltage into a level for analysis and judgment. The method for determining whether a first voltage lasts for a set duration includes: converting the first voltage into a first level; counting the number of first levels; determining whether the duration of the first level within the set duration is not less than a level number threshold; if yes, outputting a first control signal; otherwise, maintaining the output of a second control signal. Alternatively, the method for determining whether a second voltage lasts for a set duration includes: converting the second voltage into a second level; counting the number of second levels; determining whether the duration of the second level within the set duration is not less than a level number threshold; if yes, outputting a second control signal; otherwise, maintaining the output of a first control signal.

[0077] Based on the connection control method provided in this disclosure, this disclosure also provides a connector structure. (See reference...) Figure 4The diagram shows a schematic of a connector structure provided in an embodiment of this disclosure. The connector structure is applied to a detachable hot and cold compress therapy device. The connector structure provided in this embodiment includes: a plug 100, a connector 200, and a de-vibration circuit 300. A magnetic element 110 is provided in the plug 100. The connector 200 is matched with the plug 100 through insertion and removal. A magnetic induction element 210 is provided in the connector 200. During the insertion and removal process of the plug 100 and the connector 200, the magnetic induction element 210 senses that the distance between itself and the magnetic element 110 is not greater than the locking distance threshold, which is a first state. The input terminal of the de-vibration circuit 300 is electrically connected to the magnetic induction element 210. After determining that the first state lasts for a set duration, the de-vibration circuit 300 outputs a first control signal. The first control signal is used to control the detachable hot and cold compress therapy device to start working. During the insertion and removal process of plug 100 and connector 200, the distance between magnetic induction element 210 and magnetic element 110 is first determined. When magnetic induction element 210 senses that the distance between it and magnetic element 110 is not greater than the locking distance threshold, it is initially determined that the connection between plug 100 and connector 200 is locked. At this time, magnetic induction element 210 is in the first state. Then, the duration of magnetic induction element 210 being in the first state is determined. When the first state is maintained for a set duration, it is finally determined that the connection between plug 100 and connector 200 is locked. This improves the recognition accuracy of the connection locking between plug 100 and connector 200, thereby improving the situation of misjudgment and equipment malfunction.

[0078] In some embodiments, the connection control method provided in this disclosure can also solve the problem that when the connection between the plug 100 and the connector 200 is locked, the user's misoperation may be identified as a disconnection, causing the host device to stop working. For example, during the insertion and removal of the plug 100 and the connector 200, when the magnetic induction element 210 senses that the distance between it and the magnetic element 110 is greater than the locking distance threshold, it enters a second state; after the de-shaking circuit 300 determines that the second state lasts for a set duration, it outputs a second control signal, which is used to control the detachable hot and cold compress therapy device to stop working. First, the distance between the magnetic sensing element 210 and the magnetic element 110 is determined. When the magnetic sensing element 210 senses that the distance between it and the magnetic element 110 is greater than the locking distance threshold, it is initially determined that the connection between the plug 100 and the connector 200 is broken. At this time, the magnetic sensing element 210 is in the second state. Then, the duration of the magnetic sensing element 210 being in the second state is determined. If the second state is maintained for a set duration, it is finally determined that the connection between the plug 100 and the connector 200 is broken. If the duration of the second state does not reach the set duration, it is finally determined that the connection between the plug 100 and the connector 200 is still locked. This improves the recognition accuracy of the connection break between the plug 100 and the connector 200, thereby improving the situation of false judgment and equipment accidental stoppage.

[0079] In some embodiments, the state of the magnetic sensing element 210 provided in this disclosure can be determined after being converted into a voltage. (See reference...) Figure 5 The diagram shown is a structural schematic of another connector structure provided in this embodiment of the present disclosure. The de-jitter circuit 300 provided in this embodiment of the present disclosure includes: a generation circuit 310 and a processing circuit 320; the input terminal of the generation circuit 310 is electrically connected to the magnetic induction element 210; the generation circuit 310 generates a first voltage according to a first state and then outputs it, or the generation circuit 310 generates a second voltage according to a second state and then outputs it; the input terminal of the processing circuit 320 is electrically connected to the output terminal of the generation circuit 310; the processing circuit 320 determines the duration of the first voltage and then outputs a first control signal, or the processing circuit 320 determines the duration of the second voltage and then outputs a second control signal.

[0080] refer to Figure 6 The diagram shows a schematic of a generation circuit according to an embodiment of this disclosure. The generation circuit 310 includes a power supply VDD, a pull-up resistor R1, and a filter circuit 311. The output terminal of the power supply VDD is electrically connected to the first terminal of the pull-up resistor R1, and the second terminal of the pull-up resistor R1 is electrically connected to the input terminal of the filter circuit 311, serving as the input terminal of the generation circuit 310. The output terminal of the filter circuit 311 is the output terminal of the generation circuit 310. In some embodiments, the filter circuit 311 includes a filter resistor R2 and a filter capacitor C. The first terminal of the filter resistor R2 is electrically connected to the second terminal of the pull-up resistor R1, and the second terminal of the filter resistor R2 is electrically connected to the first terminal of the filter capacitor C, serving as the output terminal of the filter circuit 311. The second terminal of the filter capacitor C is electrically connected to the ground terminal GND. The resistance value of the pull-up resistor R1 provided in this embodiment can range from 4.7kΩ to 10kΩ. The filter circuit 311 can be designed to filter out high-frequency glitches caused by mechanical bouncing and magnetic field fluctuations during the insertion and removal of the plug 100 and connector 200. For example, the resistance of the filter resistor R2 can be 1kΩ and the capacitance of the filter capacitor C can be 0.1μF.

[0081] Continue as Figure 6As shown, when the magnetic induction element 210 is in the first state, it can be in a conducting state, forming a current path between the power supply VDD and the magnetic induction element 210, thus lowering the voltage at the first terminal of the filter resistor R2, resulting in a first voltage of 0V transmitted from the generation circuit 310 to the processing circuit 320. Alternatively, when the magnetic induction element 210 is in the second state, it can be in a high-resistance state, preventing the formation of a current path between the power supply VDD and the magnetic induction element 210, but forming a current path between the power supply VDD and the processing circuit 320, resulting in a second voltage that is essentially the voltage of the power supply VDD transmitted from the generation circuit 310 to the processing circuit 320. Therefore, by judging the first and second voltages, it is possible to preliminarily determine whether the plug 100 and the connector 200 are in a locked connection state.

[0082] In some embodiments, during the voltage analysis and judgment process provided by this disclosure, the voltage can be converted into a level for analysis and judgment. (See reference...) Figure 7 The diagram shows a schematic of a processing circuit according to an embodiment of this disclosure. The processing circuit 320 includes a comparator circuit 321, whose input terminal is electrically connected to the output terminal of the generator circuit 310. The comparator circuit 321 converts a first voltage to a first level and outputs it, or converts a second voltage to a second level and outputs it. For example, the comparator circuit 321 compares the input voltage with a reference voltage, thereby converting the 0V first voltage to a low level, or converting a second voltage (approximately the power supply voltage) to a high level. Two levels; a counting circuit 322, the input of which is electrically connected to the output of a comparator circuit 321; the counting circuit 322 counts the number of the first level, or the counting circuit 322 counts the number of the second level; a judgment circuit 323, the input of which is electrically connected to the output of the counting circuit 322; the judgment circuit 323 outputs a first control signal when it determines that the number of the first level within a set time period is not less than a level number threshold, or the judgment circuit 323 outputs a second control signal when it determines that the number of the second level within a set time period is not less than a level number threshold.

[0083] In some embodiments, the magnetic element 110 provided in this disclosure includes a magnet, such as N52 neodymium iron boron, with a nickel-copper-nickel three-layer electroplating layer and the S pole facing outwards; and during the insertion and removal of the plug 100 and the connector 200, the S pole of the magnet faces the magnetic induction element 210. The magnetic element 110 can be triangular in shape, such as an isosceles triangle, and its dimensions can include, but are not limited to, a base of 8mm, a leg of 6mm, and a thickness of 4.5mm.

[0084] In some embodiments, the magnetic sensing element 210 provided in this disclosure includes a Hall switch, such as a unipolar Hall switch. The first state of the Hall switch provided in this disclosure is a conducting state, and the second state is a high-resistance state.

[0085] In another aspect, this disclosure also provides a detachable hot and cold compress therapy device, including the connector structure provided in any of the above embodiments.

[0086] In some embodiments, the detachable hot and cold compress therapy device provided in this disclosure includes a processor, which may be located in a host device, and the de-shaking circuit 300 may be integrated into the processor, including but not limited to.

[0087] In summary, the embodiments of this disclosure provide a connection control method, a connector structure, and a detachable hot and cold compress therapy device. During the insertion and removal of the connector and plug, the distance between the magnetic induction element and the magnetic element is first determined. When the magnetic induction element senses that the distance between it and the magnetic element is not greater than the locking distance threshold, it is initially determined that the connection between the connector and the plug is locked, at which time the magnetic induction element is in a first state. Then, the duration of the magnetic induction element being in the first state is determined.
