Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a working state control device and method for an adsorption bowl. Background Art

[0002] When using an adsorption bowl for electrode treatment, adsorption bowls of different sizes need to be selected according to different treatment sites. Currently, during the treatment process of most products, the adsorption pressure is rhythmically controlled to achieve a better treatment effect and prevent the skin from swelling and turning red due to long-term adsorption. However, due to the different sizes of the adsorption bowls, in some current solutions, when using the same inhalation and exhalation ratio control program, it is easy for the smaller adsorption bowl to fall due to excessive exhalation, or for the larger adsorption bowl to fail to achieve the required adsorption effect due to the small change in the pressure inside the bowl.

[0003] In summary, how to effectively control the working state of the adsorption bowl and ensure that a suitable inhalation and exhalation control strategy is used during the working process of the adsorption bowl is a technical problem that those skilled in the art urgently need to solve at present. Summary of the Invention

[0004] The purpose of the present invention is to provide a working state control device and method for an adsorption bowl to effectively control the working state of the adsorption bowl and ensure that a suitable inhalation and exhalation control strategy is used during the working process of the adsorption bowl.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A working state control device for an adsorption bowl, comprising:

[0007] A memory for storing a computer program;

[0008] A processor for executing the computer program to detect the number of connected adsorption bowls after the device main body is powered on and connected to the adsorption bowl; control the pressure at the target position to reach a preset first pressure value; determine the time required for the pressure at the target position to decrease from the first pressure value to a preset second pressure value when the rotation speed of the vacuum pump is a set first rotation speed; determine the size of the adsorption bowl currently connected to the device main body based on the time and the number of adsorption bowls; determine an inhalation and exhalation control strategy corresponding to the size based on the size, and control the working state of the adsorption bowl connected to the device main body according to the inhalation and exhalation control strategy;

[0009] Wherein, the target position is the position for detecting the air pressure inside any one adsorption bowl connected to the device main body.

[0010] In one embodiment, determining the time required for the pressure at the target position to decrease from the first pressure value to a preset second pressure value when the rotational speed of the vacuum pump is a set first rotational speed includes:

[0011] Set the set round parameter i to the initial value 1;

[0012] Close the gas path solenoid valve, turn on the vacuum pump, and control the rotational speed of the vacuum pump to be the set first rotational speed;

[0013] When it is detected that the pressure at the target position decreases to the preset second pressure value, record the time t required for the pressure at the target position to decrease from the first pressure value to the second pressure value in the i-th round i ;

[0014] After increasing the value of i by 1, determine whether the current value of i exceeds a preset round threshold N; N is a positive integer not less than 2;

[0015] If not, turn off the vacuum pump, turn on the gas path solenoid valve, and when it is detected that the pressure at the target position rises to the first pressure value, return to execute the operation of closing the gas path solenoid valve, turning on the vacuum pump, and controlling the rotational speed of the vacuum pump to be the set first rotational speed;

[0016] If so, take the average value of t1 to t N as the determined time required for the pressure at the target position to decrease from the first pressure value to the preset second pressure value when the rotational speed of the vacuum pump is the set first rotational speed;

[0017] wherein, t1 is the time required for the pressure at the target position to decrease from the first pressure value to the second pressure value in the first round, and t N is the time required for the pressure at the target position to decrease from the first pressure value to the second pressure value in the N-th round.

[0018] In one embodiment, determining the size of the adsorption bowl currently connected to the device main body based on the time and the number of adsorption bowls includes:

[0019] Based on the number of adsorption bowls, select a look-up table corresponding to the number of adsorption bowls;

[0020] When the time is within the k-th time interval listed in the look-up table, determine that the size of each adsorption bowl currently connected to the device main body is the k-th size;

[0021] wherein, k is a positive integer.

[0022] In one embodiment, after the device main body is powered on and the adsorption bowl is connected, before detecting the number of connected adsorption bowls, the processor is further configured to:

[0023] Perform a self-check on the connection status of the adsorption bowl of the device main body;

[0024] When the self-check fails, prohibit the device main body from entering the working state;

[0025] When the self-check passes, perform the operation of detecting the number of connected adsorption bowls.

[0026] In one embodiment, the performing a self-check on the connection status of the adsorption bowl of the device main body includes:

[0027] Close the gas path solenoid valve, turn on the vacuum pump, and control the rotation speed of the vacuum pump to a set second rotation speed;

[0028] Determine the time required for the pressure at the target position to drop to a preset third pressure value when the rotation speed of the vacuum pump is the set second rotation speed, and use it as the time to be detected;

[0029] When the time to be detected is lower than a preset first time, determine that the self-check fails, and output a first warning message indicating a blocked gas path.

[0030] In one embodiment, the processor is further configured to:

[0031] When the rotation speed of the vacuum pump is the set second rotation speed, if the pressure at the target position still does not drop to the third pressure value after a second time, determine that the self-check fails, and output a second warning message indicating a system leak.

[0032] In one embodiment, the processor is further configured to:

[0033] Receive a strategy switching instruction, and control the working state of the adsorption bowl connected to the device main body according to the suction and exhaust control strategy specified by the strategy switching instruction.

[0034] In one embodiment, the processor is further configured to:

[0035] Receive a strategy parameter modification instruction, and modify the parameter data in the suction and exhaust control strategy specified by the strategy parameter modification instruction.

[0036] In one embodiment, the first pressure value is lower than the standard atmospheric pressure.

[0037] A method for controlling the working state of an adsorption bowl, which is applied to a processor, and the method for controlling the working state of the adsorption bowl includes:

[0038] After the device main body is powered on and connected to the adsorption bowl, detect the number of connected adsorption bowls;

[0039] Control the pressure at the target position to reach a preset first pressure value;

[0040] Determine the time required for the pressure at the target position to decrease from the first pressure value to a preset second pressure value when the rotational speed of the vacuum pump is a set first rotational speed;

[0041] Based on the time and the number of adsorption bowls, determine the size of the adsorption bowls currently connected to the device main body;

[0042] Based on the size, determine an air intake and exhaust control strategy corresponding to the size, and control the working state of the adsorption bowls connected to the device main body according to the air intake and exhaust control strategy;

[0043] Wherein, the target position is the air pressure detection position inside any one of the adsorption bowls connected to the device main body.

[0044] By applying the technical solution provided by the embodiments of the present invention, the size of the suction cup currently connected to the device body can be detected, that is, the size of the currently connected suction cup can be detected, so as to select a suction and exhaust control strategy suitable for this size. Specifically, after the device body is powered on and started and connected to the suction cup, this application will detect the number of connected suction cups, and then control the pressure at the target position to reach a preset first pressure value. After that, it is determined that, when the rotational speed of the vacuum pump is the set first rotational speed, the time required for the pressure at the target position to drop from the first pressure value to a preset second pressure value. It can be understood that for suction cups of different sizes and different numbers, the value of this time will be different. In other words, after determining this time and the number of suction cups, the size of the suction cup currently connected to the device body can be determined, that is, the sizes of the suction cups currently connected to the device body can be determined. After that, a reasonable suction and exhaust control strategy corresponding to this size can be determined based on the size of the suction cup, and then the working state of the suction cup connected to the device body can be controlled according to this suction and exhaust control strategy. Therefore, the situation that the smaller suction cup is likely to fall off and the larger suction cup cannot achieve the required effect in the traditional solution due to the use of the same suction and exhaust ratio control program will not occur. And in the solution of this application, after the device body is powered on and started and connected to the suction cup, the size of the suction cup currently connected to the device body and the corresponding suction and exhaust control strategy can be automatically determined, that is, there is no need for the user to independently select the suction and exhaust control strategy. The process of this application determining the size of the suction cup currently connected to the device body and the corresponding suction and exhaust control strategy is imperceptible to the user and will not increase the complexity of the user operation, which is beneficial to ensuring the user experience.

[0045] In summary, the solution of this application ensures that a suitable suction and exhaust control strategy is used during the working process of the suction cup and does not increase the complexity of the user operation by automatically determining the size of the suction cup currently connected to the device body and the corresponding suction and exhaust control strategy.

[0050] The core of the present invention is to provide a device for controlling the working state of an adsorption bowl. By automatically determining the size of the adsorption bowl currently connected to the device main body and the corresponding air intake and exhaust control strategies, it is ensured that a suitable air intake and exhaust control strategy is used during the working process of the adsorption bowl, and the complexity of user operation is not increased.

[0051] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] Please refer to Figure 1 , Figure 1 Schematic diagram of the structure of a device for controlling the working state of an adsorption bowl in the present invention. The device for controlling the working state of the adsorption bowl may include:

[0053] A memory 101 for storing a computer program;

[0054] A processor 102 for executing the computer program to detect the number of adsorption bowls connected after the device main body is powered on and connected to an adsorption bowl; control the pressure at the target position to reach a preset first pressure value; determine the time required for the pressure at the target position to decrease from the first pressure value to a preset second pressure value when the rotational speed of the vacuum pump is a set first rotational speed; determine the size of the adsorption bowl currently connected to the device main body based on the time and the number of adsorption bowls; determine an air intake and exhaust control strategy corresponding to the size, and control the working state of the adsorption bowl connected to the device main body according to the air intake and exhaust control strategy

[0055] Specifically, the device main body of the present application may be the main part of an electrotherapy product. The electrotherapy product can provide electrode treatment for users, and the rest of the electrotherapy product except the adsorption bowl is the device main body described in the present application. Of course, the specific structural composition of the device main body can be set and adjusted according to the actual situation as long as it can effectively provide electrode treatment for users. For example Figure 2It is a schematic structural diagram of the device main body in a specific embodiment, showing the vacuum pump, gas path solenoid valve, and air pressure sensor included in the device main body. Of course, in actual applications, the device main body may include more components to achieve its functions. And, Figure 2 In this application, an MCU is specifically used to implement the working state control device of the adsorption bowl of the present application, and the MCU has a memory and a processor.

[0056] The solution of the present application stores a computer program through the memory 101, and executes the computer program through the processor 102 to realize the control of the working state of the adsorption bowl.

[0057] Specifically, during electrode treatment, due to different treatment sites, different user requirements, etc., the number and size of the adsorption bowls selected will be different. However, it should be noted that during a single treatment, if the device main body is connected to multiple adsorption bowls, the sizes of these adsorption bowls should be the same, that is, the device main body usually does not connect two different sizes of adsorption bowls at the same time.

[0058] After the device main body is powered on and connected to the adsorption bowl, the number of connected adsorption bowls can be automatically detected. The specific detection method can be set and adjusted according to the actual situation, as long as it can effectively detect the number of connected adsorption bowls. For example, by detecting the relevant level states of each interface, it can be determined which interfaces are connected to the adsorption bowl. Of course, there can be other detection methods in other specific embodiments.

[0059] In a specific embodiment of the present invention, after the device main body is powered on and connected to the adsorption bowl, before detecting the number of connected adsorption bowls, the processor 102 can also be used for:

[0060] Self-check the connection state of the adsorption bowl of the device main body;

[0061] When the self-check fails, prohibit the device main body from entering the working state;

[0062] When the self-check passes, perform the operation of detecting the number of connected adsorption bowls.

[0063] This embodiment takes into account that after the device main body is powered on and connected to the adsorption bowl, the connection state of the adsorption bowl of the device main body can be self-checked, thereby ensuring the connection reliability of the adsorption bowl and avoiding danger to the user.

[0064] There are various specific ways to detect the connection state of the adsorption bowl, which can be set according to actual needs.

[0065] If the self-check passes, it indicates that the connection status of the adsorption bowl is normal, and subsequent operations can be executed normally, that is, the operation of detecting the number of connected adsorption bowls described above can be performed. If the self-check fails, it indicates that the connection status of the adsorption bowl is abnormal. To ensure safety, the main body of the device will be prohibited from entering the working state. Only when the abnormality is eliminated, that is, when the self-check of the connection status of the adsorption bowl of the main body of the device is performed again and the self-check passes, will the main body of the device be allowed to enter the working state.

[0066] In a specific embodiment of the present invention, the self-check of the connection status of the adsorption bowl for the main body of the device may specifically include:

[0067] Close the gas path solenoid valve, turn on the vacuum pump, and control the rotation speed of the vacuum pump to a set second rotation speed;

[0068] Determine the time required for the pressure at the target position to drop to a preset third pressure value when the rotation speed of the vacuum pump is the set second rotation speed, and use it as the time to be detected;

[0069] When the time to be detected is lower than the preset first time, determine that the self-check fails and output a first warning message indicating a gas path blockage.

[0070] As described above, there can be various specific implementation methods for detecting the connection status of the adsorption bowl. This embodiment takes into account that when the connection status of the adsorption bowl is abnormal, a relatively common situation is a gas path blockage. In this regard, in this embodiment, the gas path solenoid valve will be closed, the vacuum pump will be turned on, and the rotation speed of the vacuum pump will be controlled to the set second rotation speed. At this time, the vacuum pump will extract the air inside each adsorption bowl, causing the gas pressure inside each adsorption bowl to drop. When the pressure at the target position drops to the preset third pressure value, the time to be detected can be obtained.

[0071] The value of the second rotation speed, the value of the third pressure value, and the specific value of the first time can all be set and adjusted according to actual needs. For example, in one scenario, the value of the third pressure value is set to -30 kPa, and the first time is set to 0.2 seconds. That is to say, if the pressure at the target position drops to -30 kPa within 0.2 seconds, it can be considered that there is a gas path blockage, so it can be determined that the self-check fails and a first warning message indicating a gas path blockage is output.

[0072] Furthermore, in a specific embodiment of the present invention, the processor 102 can also be used for:

[0073] When, at the set second rotation speed of the vacuum pump, after a second time, the pressure at the target position still has not dropped to the third pressure value, determine that the self-check fails and output a second warning message indicating a system air leak.

[0074] This implementation further takes into account that in addition to air duct blockage, system air leakage is also a relatively common situation. Therefore, when the rotational speed of the vacuum pump is the set second rotational speed, if the pressure at the target position still has not decreased to the third pressure value after the second elapsed time, it can also be determined that the self-check fails, and a second warning message indicating system air leakage is output. For example, in one scenario, the second elapsed time is specifically set to 5 seconds, and the third pressure value is set to -30 kPa. That is to say, if the pressure at the target position has not decreased to -30 kPa within 5 seconds, it can be considered that system air leakage has occurred. Therefore, it can be determined that the self-check fails, and a second warning message indicating system air leakage is output.

[0075] After the device main body is powered on and the adsorption bowl is connected, the processor can detect the number of adsorption bowls connected to the working state control device of the adsorption bowl. After that, it will control the pressure at the target position to reach the preset first pressure value.

[0076] In the solution of this application, considering that for adsorption bowls of different sizes, when a fixed rotational speed of the vacuum pump is adopted, the change speed of the gas pressure inside the bowl is different. The larger the size, it means the larger the space inside the bowl. When the rotational speed of the vacuum pump is fixed, the change speed of the gas pressure is slower.

[0077] In response to this, in the solution of this application, it will first control the pressure at the target position to reach the preset first pressure value. After that, by determining the elapsed time required for the pressure at the target position to decrease from the first pressure value to the preset second pressure value when the rotational speed of the vacuum pump is the set first rotational speed, the size of the adsorption bowl can be determined in combination with the number of adsorption bowls.

[0078] The value of the first pressure value can be set and adjusted according to actual needs. For example, in a simple setting method, it is set to 1 standard atmospheric pressure. That is to say, at this time, only the air duct solenoid valve needs to be opened to allow air to enter the inner space of the adsorption bowl, and the pressure at the target position can reach the preset first pressure value.

[0079] When the device main body is connected to multiple adsorption bowls, since the air ducts between the adsorption bowls are connected, that is, the air pressure inside the bowls of each adsorption bowl is the same. Therefore, the target position described in this application is the air pressure detection position inside the bowl of any one adsorption bowl connected to the device main body. That is to say, a pressure sensor can be set in the inner space of any one adsorption bowl to realize the pressure detection at this position, and this position can be used as the target position described in this application. In practical applications, the specific selection of the target position can be set and adjusted according to needs, which does not affect the implementation of the present invention.

[0080] After the pressure at the control target position reaches the preset first pressure value, it is necessary to determine the time required for the pressure at the target position to decrease from the first pressure value to the preset second pressure value when the rotational speed of the vacuum pump is the set first rotational speed.

[0081] After the pressure at the control target position reaches the preset first pressure value, it is necessary to determine the time required for the pressure at the target position to decrease from the first pressure value to the preset second pressure value when the rotational speed of the vacuum pump is the set first rotational speed.

[0082] For example, in one case, after the pressure at the control target position reaches the preset first pressure value, the gas path solenoid valve is closed, the vacuum pump is turned on, and the timing starts, and the rotational speed of the vacuum pump is controlled to be the set first rotational speed. As the vacuum pump continuously extracts the air inside the adsorption bowl, the pressure at the target position will continuously decrease. When it decreases to the preset second pressure value, the timing ends, and thus the time required for the pressure at the target position to decrease from the first pressure value to the preset second pressure value is obtained.

[0083] Further, in a specific embodiment of the present invention, determining the time required for the pressure at the target position to decrease from the first pressure value to the preset second pressure value when the rotational speed of the vacuum pump is the set first rotational speed may specifically include:

[0084] Step 1: Set the set round parameter i to the initial value 1;

[0085] Step 2: Close the gas path solenoid valve, turn on the vacuum pump, and control the rotational speed of the vacuum pump to be the set first rotational speed;

[0086] Step 3: When it is detected that the pressure at the target position decreases to the preset second pressure value, record the time t required for the pressure at the target position to decrease from the first pressure value to the second pressure value in the i-th round i ;

[0087] Step 4: After adding 1 to the value of i, determine whether the current value of i exceeds the preset round threshold N; N is a positive integer not less than 2;

[0088] If not, turn off the vacuum pump, turn on the gas path solenoid valve, and when it is detected that the pressure at the target position rises to the first pressure value, return to execute the operation of the above step 2;

[0089] If so, execute step 5: Take the average value of t1 to t N as the determined time required for the pressure at the target position to decrease from the first pressure value to the preset second pressure value when the rotational speed of the vacuum pump is the set first rotational speed;

[0090] Among them, t1 is the time taken for the pressure at the recorded target position to decrease from the first pressure value to the second pressure value in the first round, and t N is the time taken for the pressure at the recorded target position to decrease from the first pressure value to the second pressure value in the Nth round.

[0091] In this implementation manner, the time taken described in step S103 is obtained by taking the average value of multiple rounds of data. Compared with the example above, this method is beneficial to ensure the accuracy of the obtained time taken.

[0092] For example, in a certain situation, the first pressure value is specifically -10 kPa, the second pressure value is specifically -30 kPa, i is a set round parameter, and its initial value is 1, that is, the detection of the first round is carried out first. At this time, the above-mentioned step two is triggered for the first time, and the current pressure at the target position is -10 kPa. After that, the gas path solenoid valve is closed, the vacuum pump is turned on, and the rotation speed of the vacuum pump is controlled to be the set first rotation speed. In practical applications, the rotation speed of the vacuum pump is usually controlled by PWM pulses. For example, in a certain situation, setting the duty cycle of the PWM pulse to 50% can make the rotation speed of the vacuum pump maintain the set first rotation speed.

[0093] As the vacuum pump operates, the gas in the adsorption bowl is continuously extracted, and the pressure at the target position will also continuously decrease from -10 kPa. In this example, when it is detected that the pressure at the target position decreases to -30 kPa, the time taken t1 for the pressure at the target position to decrease from the first pressure value of -10 kPa to the second pressure value of -30 kPa in the first round can be recorded.

[0094] Then, the value of i is incremented by 1. In this example, after the value of i is incremented by 1, it is equal to 2 at this time. At this time, it is necessary to determine whether the current value of i exceeds the preset round threshold N. N is a positive integer not less than 2. For example, in this example, N = 10, that is, 10 rounds of detection are required. Since i = 2 < 10 at this time, the vacuum pump will be turned off and the gas path solenoid valve will be opened, so that the gas continuously floods into the bowl, and the pressure at the target position will rise. When it is detected that the pressure at the target position rises to -10 kPa, the operation of the above-mentioned step two is returned to, and the process of the second round is started, and so on until the Nth round is completed.

[0095] Since N = 10 in this example, 10 rounds are required, that is, the operation of the above-mentioned step three will be executed 10 times in total, obtaining t1 to t 10 a total of 10 values. Finally, the average value of t1 to t 10 is used as the determined time taken for the pressure at the target position to decrease from the first pressure value to the preset second pressure value when the rotation speed of the vacuum pump is the set first rotation speed.

[0096] After determining the time required for the pressure at the target position to decrease from the first pressure value to the preset second pressure value when the rotational speed of the vacuum pump is the set first rotational speed, based on this time and the number of adsorption bowls, the size of the adsorption bowls currently connected to the device body can be determined.

[0097] Specifically, both the number and size of the adsorption bowls connected to the device body will affect the time required for the pressure at the target position to decrease from the first pressure value to the preset second pressure value. Therefore, after obtaining this time and combining it with the number of adsorption bowls, the size of the adsorption bowls currently connected to the device body can be determined.

[0098] For example, in one case, there are 3 different sizes of adsorption bowls. For example, they are large bowls with an inner space of 64 cm 3 medium bowls with an inner space of 16 cm 3 and small bowls with an inner space of 8 cm 3 respectively. Then, based on the time obtained in S103 and the number of adsorption bowls, according to the preset corresponding relationship, it can be determined whether the size of the adsorption bowls currently connected to the device body is a large bowl, a medium bowl, or a small bowl. And as described above, the device body usually does not connect two different sizes of adsorption bowls at the same time.

[0099] Determining the size of the adsorption bowls currently connected to the device body based on the time and the number of adsorption bowls may specifically include:

[0100] Based on the number of adsorption bowls, select a look-up table corresponding to the number of adsorption bowls;

[0101] When the time is within the k-th time interval listed in the look-up table, determine that the size of each adsorption bowl currently connected to the device body is the k-th size;

[0102] where k is a positive integer.

[0103] This implementation mode takes into account that the size of the adsorption bowls currently connected to the device body can be conveniently and quickly determined through the look-up table. Specifically, when the number of adsorption bowls connected to the device body is different, a look-up table corresponding to the number of adsorption bowls is selected. That is to say, different look-up tables are pre-configured for different numbers of adsorption bowls.

[0104] After obtaining the required look-up table, when the time required for the pressure at the target position determined by the above operation to decrease from the first pressure value to the preset second pressure value falls within the k-th time interval listed in the look-up table, it can be determined that the size of each adsorption bowl currently connected to the device body is the k-th size. For example, in a specific example, there are 3 types of adsorption bowl sizes. When the time obtained from the above operation falls within the first time interval listed in the look-up table, it is determined that the size of each adsorption bowl currently connected to the device body is the first size, that is, they are all large bowls. If the time obtained from the above operation falls within the second time interval listed in the look-up table, it will be determined that the size of each adsorption bowl currently connected to the device body is the second size, that is, they are all medium bowls. Correspondingly, if the time obtained from the above operation falls within the third time interval listed in the look-up table, it will be determined that the size of each adsorption bowl currently connected to the device body is the third size, that is, they are all small bowls.

[0105] In practical applications, it is a relatively common solution that there are 3 types of adsorption bowl sizes. Of course, in other scenarios, there can be more size divisions. In addition, it can be understood that in the solution of this application, when determining the size of the adsorption bowl currently connected to the device body, it is not necessary to determine the specific size value, only to determine which type of size among all the sizes the adsorption bowl currently connected to the device body belongs to. Subsequently, the air intake and exhaust control strategy corresponding to this type of size can be obtained.

[0106] Based on the size, the air intake and exhaust control strategy corresponding to the size can be determined, and the working state of the adsorption bowl connected to the device body can be controlled according to the air intake and exhaust control strategy.

[0107] After obtaining the size of the adsorption bowl currently connected to the device body, since different sizes correspond to different air intake and exhaust control strategies, the air intake and exhaust control strategy corresponding to this size can be determined based on the size determined by the above operation, and the working state of each adsorption bowl connected to the device body can be controlled according to this air intake and exhaust control strategy;

[0108] It can be understood that for different sizes, what specific air intake and exhaust control strategies should be set can be preset by the staff. For example, the staff sets different air intake and exhaust control strategies for adsorption bowls of different sizes through experimental data.

[0109] In addition, it should be noted that the specific content in the air intake and exhaust control strategy can be set and adjusted according to actual needs. However, it usually needs to include the air intake duration, the maintenance duration, and the exhaust duration. That is, within each execution cycle, first, the air path solenoid valve is closed, and the vacuum pump is turned on, so that the vacuum pump sucks out the gas in the bowl. The duration of this process is the air intake duration. After the air intake ends, the air path solenoid valve remains closed, and the vacuum pump is also turned off. The duration of this process is the maintenance duration. Finally, the air path solenoid valve is opened, and the vacuum pump is turned off, so that the external air is put into the bowl. The duration of this process is the exhaust duration. In practical applications, the larger the size of the adsorption bowl, the higher the air intake duration and the exhaust duration can usually be set, so that for smaller-sized adsorption bowls, they will not fall off due to excessive exhaust, and for larger-sized adsorption bowls, users can have a good adsorption experience.

[0110] The specific value of the first pressure value can be set and adjusted according to actual needs. For example, in one of the above examples, the first pressure value is specifically set to 1 standard atmosphere. In another example above, the first pressure value is specifically set to -10 kPa. In a specific embodiment of the present invention, the first pressure value is lower than the standard atmosphere. For example, in practical applications, the embodiment of -10 kPa is usually adopted, so that the first pressure value is lower than the standard atmosphere.

[0111] This is because if the first pressure value is specifically set to 1 standard atmosphere, it will increase the detection error. Specifically, if the first pressure value is set to 1 standard atmosphere, when the vacuum pump starts to work, even if each adsorption bowl is vertically placed on the treatment site, it is very easy to have the situation that one or more adsorption bowls do not fit well with the treatment site, that is, there are gaps in the fitting surface between the adsorption bowl and the treatment site. This means that when the vacuum pump starts to work, after a certain delay, each adsorption bowl can fit well with the treatment site. And in different situations, the value of this delay is different, with strong contingency, depending on factors such as the placement position and placement posture of the adsorption bowl. Therefore, such a method is likely to cause errors in the determined time-consuming, and thus reduces the reliability of the solution of this application.

[0112] If the first pressure value is set to be lower than the standard atmospheric pressure, it means that in the process of determining the time required for the pressure at the target position to decrease from the first pressure value to the preset second pressure value, when this process starts to be executed, the vacuum pump has already started working and has pumped out a part of the gas inside the bowl. At this time, the gas pressure everywhere inside the bowl has reached the first pressure value, for example, -10 kPa in the above example. At this time, since the air pressure inside the bowl is lower than the external atmospheric pressure, each adsorption bowl can fit well and tightly with the treated part, which makes it possible to reduce errors in the subsequent process, that is, the corresponding time can be accurately detected, which is beneficial to ensuring the reliability of the solution of the present application.

[0113] In a specific embodiment of the present invention, the processor 102 may further be configured to:

[0114] Receive a strategy switching instruction, and control the working state of the adsorption bowl connected to the device body according to the air intake and exhaust control strategy specified by the strategy switching instruction.

[0115] As can be seen from the above description, in the solution of the application, the size of the adsorption bowl currently connected to the device body can be automatically determined, and then an appropriate air intake and exhaust control strategy can be automatically selected. This embodiment further considers that the user can be allowed to select the air intake and exhaust control strategy according to needs. For example, the user operates relevant buttons, etc., so that the processor 102 can receive the strategy switching instruction, and then control the working state of the adsorption bowl connected to the device body according to the air intake and exhaust control strategy specified by the strategy switching instruction, so that the working state of the adsorption bowl meets the requirements of the strategy switching instruction, that is, meets the requirements of the user, and improves the user experience in some occasions.

[0116] In a specific embodiment of the present invention, the processor 102 may further be configured to:

[0117] Receive a strategy parameter modification instruction, and modify the parameter data in the air intake and exhaust control strategy specified by the strategy parameter modification instruction.

[0118] As described above, the specific content in the air intake and exhaust control strategy can be set and adjusted according to actual needs, but usually includes the air intake duration, the maintenance duration, and the air exhaust duration. In this embodiment, the user is also allowed to modify the parameter data in the air intake and exhaust control strategy, that is, the user performs relevant operations so that the processor 102 can receive the strategy parameter modification instruction, and then modifies the parameter data in the air intake and exhaust control strategy specified by the strategy parameter modification instruction. It can be seen that this embodiment further improves the flexibility of use of the solution of the present application.

[0119] By applying the technical solution provided by the embodiment of the present invention, the size of the suction cup currently connected to the device main body can be detected, that is, the size of the currently connected suction cup can be detected, so as to select a suction and exhaust control strategy suitable for this size. Specifically, after the device main body is powered on and started and connected to the suction cup, this application will detect the number of connected suction cups, and then control the pressure at the target position to reach a preset first pressure value. After that, it is determined that when the rotation speed of the vacuum pump is the set first rotation speed, the time required for the pressure at the target position to drop from the first pressure value to a preset second pressure value. It can be understood that for suction cups of different sizes and different numbers, the value of this time will be different. In other words, after determining this time and the number of suction cups, the size of the suction cup currently connected to the device main body can be determined, that is, the sizes of the suction cups currently connected to the device main body can be determined. After that, a reasonable suction and exhaust control strategy corresponding to this size can be determined based on the size of the suction cup, and then the working state of the suction cup connected to the device main body can be controlled according to this suction and exhaust control strategy. Therefore, the situation that the smaller suction cup is likely to fall off and the larger suction cup cannot achieve the required effect in the traditional solution when using the same suction and exhaust ratio control program will not occur. And in the solution of this application, after the device main body is powered on and started and connected to the suction cup, the size of the suction cup currently connected to the device main body and the corresponding suction and exhaust control strategy can be automatically determined, that is, the user does not need to independently select the suction and exhaust control strategy. The process of this application determining the size of the suction cup currently connected to the device main body and the corresponding suction and exhaust control strategy is imperceptible to the user and will not increase the complexity of the user operation, which is beneficial to ensuring the user experience.

[0120] In summary, the solution of this application ensures that a suitable suction and exhaust control strategy is used during the working process of the suction cup by automatically determining the size of the suction cup currently connected to the device main body and the corresponding suction and exhaust control strategy, and does not increase the complexity of the user operation.
