[0042] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0043] Reference is made to Figure 1 , Figure 1 A flowchart of a piezoelectric shock wave discharge control method provided by the present application is provided. The piezoelectric shock wave discharge control method is applied to a controller of a piezoelectric shock wave therapeutic instrument, and includes the following steps.

[0044] S101: In response to a first control instruction, a charging circuit of the piezoelectric shock wave therapeutic instrument is controlled to charge an energy storage element.

[0045] Specifically, considering the technical problems in the background art above and the active control of the start and end of charging can actively limit the time of high voltage, in the present application, in response to the first control instruction, the charging circuit of the piezoelectric shock wave therapeutic instrument is controlled to charge the energy storage element, thereby realizing the control of the start of charging. It is worth mentioning that since the subsequent steps can actively control the charging circuit to stop charging after the discharge ends, the control of the start of charging in this step can be the beginning of each discharge action, that is, charging needs to be performed before discharge.

[0046] Specifically, the charging device can be of various types, for example, a full-bridge rectifier circuit, etc., which is not limited in the embodiments of the present application.

[0047] S102: When a real-time voltage value of the energy storage element reaches a preset threshold value, a discharge control action is performed.

[0048] Specifically, considering that the piezoelectric shock wave therapeutic instrument usually has requirements for the voltage value during discharge, in the embodiments of the present application, a threshold value of the voltage value is preset. Therefore, during the charging process, if it is monitored that the real-time voltage value of the energy storage element reaches the preset threshold value, the discharge control action can be performed, that is, on the one hand, the charging circuit is controlled to stop charging the energy storage element, to ensure that the charging action only meets the basic discharge requirements, thereby greatly shortening the working time of the charging circuit and making the energy storage element no longer have high voltage after the discharge is completed, thereby reducing the pressure on related elements and improving the service life and safety; on the other hand, the discharge circuit is controlled to discharge, so that normal discharge can be performed under the condition of meeting the voltage requirements.

[0049] Specifically, also because charging of the energy storage element is stopped when the preset threshold is reached, it means that the next time the energy storage element needs to be discharged, the charging action of S101 still needs to be started, that is, during the period from the current discharge end to the next time the energy storage element needs to be discharged, the energy storage element no longer has high voltage.

[0050] The real-time voltage value of the energy storage element can be obtained by various types of voltage detection circuits, which are not limited in the embodiments of the present application.

[0051] Specifically, the preset threshold can be set autonomously, for example, it can be 5000V, etc., which is not limited in the embodiments of the present application.

[0052] In addition, it is pointed out that, in the embodiments of the present application, the discharge control action is performed when the real-time voltage value of the energy storage element reaches the preset threshold, avoiding the natural discharge process of the energy storage element, so that the discharge voltage is more accurate.

[0053] S103: in response to the discharge end instruction, controlling the discharge circuit to stop discharging;

[0054] The discharge control action includes: controlling the charging circuit to stop charging the energy storage element and controlling the discharge circuit to discharge.

[0055] Specifically, in order to ensure that the discharge circuit stops discharging after the discharge is completed, thereby improving safety, the present application can also respond to the discharge end instruction to control the discharge circuit to stop discharging.

[0056] The present application provides a discharge control method of piezoelectric shock wave, considering that the active control of charging start and end action can actively limit the time of high voltage existing, therefore, in the present application, in response to the first control instruction, the charging circuit of the piezoelectric shock wave therapeutic instrument is controlled to charge the energy storage element, and when the real-time voltage value of the energy storage element reaches the preset threshold, the charging circuit is controlled to stop charging and the discharge circuit is controlled to discharge, and under the control of the discharge end instruction, the discharge circuit is controlled to stop discharging, that is, when discharging is needed, the present application controls the charging start by means of instruction control, and controls the charging circuit to stop charging when the charging is up to standard and discharges at the same time, the next time the discharge is needed, the charging start can also be controlled by instruction, the energy storage element does not exist high voltage during the period from the discharge completion to the discharge start, thereby reducing the impact on the corresponding element and eliminating the safety hazard.

[0057] On the basis of the above embodiments:

[0058] As an optional embodiment, after the charging circuit of the piezoelectric shock wave therapeutic instrument is controlled to charge the energy storage element in response to the first control instruction, before the discharge circuit is controlled to stop discharging in response to the discharge end instruction, the discharge control method of the piezoelectric shock wave further comprises:

[0059] S202: when the duration of the charging circuit continuously charging the energy storage element reaches a preset duration, a discharging control action is performed.

[0060] Specifically, considering that the voltage detection circuit for detecting the real-time voltage value of the energy storage element has a possibility of failure, once a failure occurs, the real-time voltage value of the energy storage element cannot be obtained, so that the discharging control action cannot be triggered, and in combination with the fact that under normal circumstances, the charging duration will reach a certain standard after a certain time, the real-time voltage value of the energy storage element will also reach a preset threshold, therefore, in the embodiment of the present application, a preset duration is set in advance, and when the duration of the charging circuit continuously charging the energy storage element reaches the preset duration, the discharging control action is performed, so as to have two sets of mechanisms for triggering the discharging control action, even if the voltage detection circuit fails, the discharging control action can be triggered by the second set of mechanisms with a high probability.

[0061] The preset duration can be set autonomously, which is not limited in the embodiment of the present application.

[0062] As an optional embodiment, the preset duration includes a sum of a theoretical duration and a redundant charging duration.

[0063] The theoretical duration is the duration of the charging circuit charging the energy storage element to the voltage target value of the piezoelectric shock wave therapy instrument, and the redundant charging duration is the redundant charging duration corresponding to the voltage target value determined according to a preset corresponding relationship.

[0064] Specifically, the voltage target value can be set autonomously, for example, it can be equal to the preset threshold described above, and in order to ensure that the real-time voltage value of the energy storage element reaches the voltage target value, the redundant charging duration is also added.

[0065] Specifically, considering that the relationship curve between the real-time voltage value of the energy storage element and the charging time is a logarithmic curve, in the embodiment of the present application, different redundant charging durations can be set for different voltage target values, that is, a corresponding relationship between the voltage target value and the redundant charging duration is set in advance, considering that in the voltage-time curve of the energy storage element, the greater the real-time voltage value, the longer the time required for the real-time voltage value to be improved by an equal amplitude, therefore, each redundant charging duration in the preset corresponding relationship also conforms to this rule, that is, when the voltage target value is higher, the redundant charging duration is also longer, so as to ensure that the redundant charging duration can bring an equal amplitude of voltage rise to the energy storage element, and the safety can be further improved.

[0066] Of course, in addition to this specific way, the determination method of the preset duration can also be other types, which is not limited in the embodiment of the present application.

[0067] In addition, the redundant charging duration can have an upper limit value, for example, 3 ms, and the like, which is not limited in the embodiments of the present application.

[0068] As an optional embodiment, in response to the first control instruction, the charging circuit of the piezoelectric shock wave therapeutic apparatus is controlled to charge the energy storage element, and then in response to the discharge end instruction, the discharge control method of the piezoelectric shock wave further comprises:

[0069] S203: when the duration of the charging circuit continuously charging the energy storage element reaches the preset upper limit duration, performing the discharge control action;

[0070] The preset upper limit duration is the duration of the charging circuit charging the energy storage element to the preset maximum output high voltage of the piezoelectric shock wave therapeutic apparatus, and the preset upper limit duration is greater than the preset standard duration.

[0071] In order to better illustrate the embodiments of the present application, please refer to Figures 2 to 5 , Figure 2 The flowchart of another discharge control method of the piezoelectric shock wave provided by the present application, Figure 3 The voltage-time curve of the energy storage element provided by the present application, Figure 4 The voltage-time curve of another energy storage element provided by the present application, Figure 5 The voltage-time curve of another energy storage element provided by the present application, wherein, Figures 3-5 T0 in the above formula is the rising edge of the discharge control pulse, T4 is the falling edge of the discharge control pulse, T1 is the time required for the energy storage element to be charged to the preset threshold, T2 is the preset standard duration, and T3 is the preset upper limit duration.

[0072] In addition, Figure 2 S201 in the above formula is the same as S101 in the above formula, S202 is the same as S102, and S205 is the same as S103. Figure 1

[0073] Specifically, in order to further ensure that the discharge control action can be normally executed, and in combination with the consideration that the piezoelectric shock wave therapeutic apparatus is usually set to have a preset maximum output high voltage, the time point at which the energy storage element is charged to the preset maximum output high voltage, if the previous two sets of trigger execution discharge control action logic are not effective, then the excessively high voltage will have a security risk, therefore, the embodiments of the present application can perform the discharge control action when the duration of the charging circuit continuously charging the energy storage element reaches the preset upper limit duration, and the preset upper limit duration is the duration of the charging circuit charging the energy storage element to the preset maximum output high voltage of the piezoelectric shock wave therapeutic apparatus, so as to ensure that the real-time voltage value of the energy storage element will not exceed the preset maximum output high voltage, and further improve the safety.

[0074] ​As an optional embodiment, the discharge control method of the piezoelectric shock wave further comprises:

[0075] When the duration of not receiving the real-time voltage value of the energy storage element sent by the voltage detection circuit reaches the preset alarm duration, the alarm is controlled to alarm.

[0076] Specifically, considering that the discharge demand has a certain frequency after the discharge work starts, for example, 1Hz, that is, there is a discharge demand once every second, that is, after the discharge work starts, the voltage detection circuit can usually periodically detect the real-time voltage value of the energy storage element and send it to the controller, or even if the energy storage element does not have voltage, the voltage detection circuit can continue to work and send the detection result of the voltage being zero to the controller, therefore, in the embodiment of the application, when the duration of not receiving the real-time voltage value of the energy storage element sent by the voltage detection circuit reaches the preset alarm duration, the alarm is controlled to alarm, so that the staff can timely overhaul the voltage detection circuit, thereby ensuring the normal work of the piezoelectric shock wave therapeutic apparatus.

[0077] Among them, the alarm can be of various types, for example, it can be a buzzer, etc., which is not limited in the embodiment of the application.

[0078] As an optional embodiment, the discharge control method of the piezoelectric shock wave further comprises:

[0079] In response to the received modification instruction, the preset threshold is modified.

[0080] Specifically, considering that the preset threshold may need to be adjusted in some cases, therefore, the embodiment of the application provides a corresponding modification interface, so that the staff can actively modify the preset threshold.

[0081] Of course, in addition to the preset threshold, other preset parameters in the piezoelectric shock wave therapeutic apparatus can also be actively modified, which is not limited in the embodiment of the application.

[0082] As an optional embodiment, the first control instruction is the rising edge of the discharge control pulse, the discharge end instruction is the falling edge of the discharge control pulse, and the duration of the discharge control pulse is greater than the preset ceiling duration.

[0083] Specifically, considering that the charging start and the discharge end are needed in the execution process of each discharge action, therefore, in the embodiment of the application, the first control instruction and the discharge end instruction can be realized in the form of pulse, and the control mode is simple and reliable.

[0084] Among them, in order to ensure that the discharge end action is performed after the discharge action, that is, there is enough time for discharge, the duration of the discharge control pulse in the embodiment of the application is greater than the preset ceiling duration.

[0085] Specifically, in one specific embodiment, the preset threshold value can be 5000V, the preset maximum output high voltage can be 5700V, the time length of the discharge control pulse is 30ms, and the preset capping time length is 25ms.
