Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0044] In order to improve the accuracy of the calibration of the air negative ion detection equipment, the embodiment of the present application provides an ion calibration source, the specific structure of which can be seen in Figure 1 、 Figure 2 、 Figure 3 , specifically including: a flow control device 10, an ion generating device 20 and an ion control device 30.

[0045] The flow control device 10 is used to make the target gas flow through the ion generating device 20 and the ion control device 30 in sequence.

[0046] In a specific example, Figure 1As shown, the inlet of the flow control device 10 serves as the inlet of the ion calibration source, the outlet of the flow control device 10 is connected to the inlet of the ion generating device 20, the outlet of the ion generating device 20 is connected to the inlet of the ion control device 30, and the outlet of the ion control device 30 serves as the outlet of the ion calibration source.

[0047] It should be noted that Figure 1 The connection between any two devices is only illustrated by a straight line, and the connection relationship between the two devices is not specifically shown.

[0048] In another specific example, Figure 2 As shown, the inlet of the ion generating device 20 serves as the inlet of the ion calibration source, the outlet of the ion generating device 20 is connected to the inlet of the flow control device 10, the outlet of the flow control device 10 is connected to the inlet of the ion control device 30, and the outlet of the ion control device 30 serves as the outlet of the ion calibration source.

[0049] It should be noted that Figure 2 The connection between any two devices is only illustrated by a straight line, and the connection relationship between the two devices is not specifically shown.

[0050] In another specific example, Figure 3 As shown, the inlet of the ion generating device 20 serves as the inlet of the ion calibration source, the outlet of the ion generating device 20 is connected to the inlet of the ion control device 30, the outlet of the ion control device 30 is connected to the inlet of the flow control device 10, and the outlet of the flow control device 10 serves as the outlet of the ion calibration source.

[0051] It should be noted that Figure 3 The connection between any two devices is only illustrated by a straight line, and the connection relationship between the two devices is not specifically shown.

[0052] The above three examples only show three connection methods between the flow control device 10, the ion generating device 20, and the ion control device 30. In actual applications, including but not limited to these, as long as the implementation method can make the target gas flow through the ion generating device 20 and the ion control device 30 in sequence, it is within the protection scope of this application. No specific limitation is made here and it can be determined according to the specific situation.

[0053] In one specific example, the target gas is air.

[0054] The above example only shows a specific implementation method of the target gas. In practical applications, including but not limited to this, no specific limitation is made here and it can be determined according to the specific circumstances, all of which are within the scope of protection of this application.

[0055] In one specific example, the flow control device 10 is a fan.

[0056] The above example only shows a specific implementation of the flow control device 10. In practical applications, including but not limited to this, no specific limitation is made here and it can be determined according to specific circumstances, all of which are within the scope of protection of this application.

[0057] The ion generating device 20 is used to ionize the target gas flowing through the ion generating device 20 , that is, to generate positive ions and negative ions in the target gas flowing through the ion generating device 20 .

[0058] In a specific example, the ion generating device 20 is an ion generator.

[0059] It should be noted that ion generators are already very mature in the prior art and will not be described in detail here.

[0060] The above example only shows a specific implementation of the ion generating device 20. In practical applications, including but not limited to this, no specific limitation is made here and it may be determined according to the specific circumstances, and all are within the scope of protection of this application.

[0061] The ion control device 30 is used to limit the content of target ions in the target gas flowing through the device.

[0062] In one specific example, the target ion is a positive ion.

[0063] In another specific example, the target ions are negative ions.

[0064] The above two examples show two specific implementation methods of the target ions. In practical applications, including but not limited to these, no specific limitations are made here and may be determined according to specific circumstances, all of which are within the scope of protection of this application.

[0065] In this embodiment, the flow control device 10 can make the target gas flow through the ion generating device 20 and the ion control device 30 in sequence, and the ion generating device 20 can ionize the target gas flowing through itself, so that the target gas that finally flows out of the ion calibration source contains target ions. Since the ion control device 30 limits the content of target ions in the target gas flowing through itself, the content of target ions in the target gas that finally flows out of the ion calibration source will be closer to the nominal value of the content. Since the target ions can be negative ions and the target gas can be air, the content of negative ions in the air that finally flows out of the ion calibration source will be closer to the nominal value of the content. Therefore, the content of negative ions in the air output by multiple ion calibration sources with the same nominal value of the content is closer, thereby improving the accuracy of the calibration of the air negative ion detection equipment.

[0066] Another embodiment of the present application also provides another implementation of the ion calibration source, the specific structure of which can be found in Figure 4 ( Figure 4 Only in Figure 1 or Figure 5 ( Figure 5 Only in Figure 1 This embodiment, based on the embodiment provided in the previous embodiment, further includes: a gas filtering device 40.

[0067] The flow control device 10 is used to make the target gas flow through the gas filtering device 40 , the ion generating device 20 and the ion control device 30 in sequence.

[0068] It should be noted that the target gas has been described in detail in the above embodiments and will not be repeated here.

[0069] The gas filtering device 40 is used to perform ion filtration on the target gas flowing through the gas filtering device 40 .

[0070] In a specific example, Figure 4 As shown, the inlet of the gas filter device 40 serves as the inlet of the ion calibration source, and the outlet of the gas filter device 40 is connected to the inlet of the flow control device 10 .

[0071] It should be noted that Figure 4 The connection between any two devices is only illustrated by a straight line, and the connection relationship between the two devices is not specifically shown.

[0072] In another specific example, Figure 5 As shown, the inlet of the gas filtering device 40 is connected to the outlet of the flow control device 10 , and the outlet of the gas filtering device 40 is connected to the inlet of the ion generating device 20 .

[0073] It should be noted that Figure 5 The connection between any two devices is only illustrated by a straight line, and the connection relationship between the two devices is not specifically shown.

[0074] The above examples only show two implementations of the gas filter device 40. In practical applications, including but not limited to these, as long as the target gas can flow through the gas filter device 40, the ion generating device 20 and the ion control device 30 in sequence, the implementation methods are all within the protection scope of this application. No specific limitations are made here and it depends on the specific situation.

[0075] In this embodiment, the gas filter 40 is capable of filtering the target gas flowing through it through ions. Consequently, the ion content of the target gas flowing out of the gas filter 40 is reduced. Furthermore, because the target gas flows sequentially through the gas filter 40, the ion generator 20, and the ion control device 30—that is, the target gas flows through the gas filter 40 first and then through the ion generator 20—the ion content of the target gas flowing into the ion generator 20 is reduced. This reduces the possibility of affecting the ion generator 20 and ion control device 30, thereby improving the reliability of the ion calibration source.

[0076] Another embodiment of the present application provides another implementation of the ion calibration source. This implementation is further defined based on any of the implementations provided in the above embodiments:

[0077] The flow control device 10 is also used to limit the flow rate of the target gas.

[0078] It should be noted that the target gas has been described in detail in the above embodiments and will not be repeated here.

[0079] In this embodiment, because the flow control device 10 limits the flow rate of the target gas, the target gas flow rate ultimately exiting the ion calibration source is closer to the nominal flow rate value. Furthermore, because the target ions can be negative ions and the target gas can be air, the air flow rate ultimately exiting the ion calibration source is closer to the nominal flow rate value. Consequently, the air flow rates output by multiple ion calibration sources with the same nominal flow rate value are closer.

[0080] In addition, since the gas flow rate is equal to the product of the gas flow velocity and the cross-sectional area of ​​the flow channel, when the cross-sectional area of ​​the ion calibration source is fixed, the flow velocity of the target gas is positively correlated with the flow rate of the target gas, that is, changing the flow velocity of the target gas will change the flow rate of the target gas. Therefore, the flow control device 10 limits the flow velocity of the target gas, which is to limit the flow rate of the target gas.

[0081] Another embodiment of the present application provides another implementation of the ion calibration source. This implementation is further defined based on any of the implementations provided in the above embodiments:

[0082] The ion control device 30 is also used to filter non-target ions in the target gas flowing through the device.

[0083] If the target ion is positive, the non-target ion is negative; if the target ion is negative, the non-target ion is positive.

[0084] In this embodiment, since the ion control device 30 filters the non-target ions in the target gas flowing through itself, the content of non-target ions in the target gas that finally flows out of the ion calibration source is reduced. Since the non-target ions can be positive ions and the target gas can be air, the content of positive ions in the air that finally flows out of the ion calibration source is reduced, thereby reducing the possibility of affecting the calibration of the air negative ion detection equipment.

[0085] Another embodiment of the present application provides another implementation of the ion calibration source, the specific structure of which can be found in Figure 6 ( Figure 6 Only in Figure 4 This embodiment, based on any one of the above embodiments, further includes: an output structure 50.

[0086] The flow control device 10 is used to allow the target gas to flow through the gas filtering device 40 , the ion generating device 20 , the ion control device 30 and the output structure 50 in sequence.

[0087] In a specific example, Figure 5 As shown, the inlet of the output structure 50 is connected to the outlet of the ion control device 30, and the outlet of the output structure 50 serves as the outlet of the ion calibration source.

[0088] In another specific example, the inlet of the output structure 50 is connected to the outlet of the flow control device 10 , and the outlet of the output structure 50 serves as the outlet of the ion calibration source.

[0089] The above three examples only show two connection methods of the output structure 50. In practical applications, including but not limited to these, no specific limitations are made here and it can be determined according to the specific situation. All of them are within the scope of protection of this application.

[0090] The output structure 50 is used to connect to the subsequent devices of the ion calibration source, such as air negative ion detection equipment.

[0091] In this embodiment, since this embodiment includes the output structure 50 , this embodiment makes the connection between itself and subsequent devices more convenient.

[0092] Another embodiment of the present application provides another implementation of the ion calibration source, the specific structure of which can be found in Figure 7 This implementation, based on any of the above embodiments, further includes: a first human interaction device 110 and a controller 120 .

[0093] The first manual interaction device 110 is connected to the controller 120 , and the controller 120 is connected to the ion control device 30 .

[0094] If the ion control device 30 includes a positive and negative voltage module, the positive and negative voltage module is connected to the controller 120. If the target ions are negative ions, the controller 120 controls the positive and negative voltage module to provide a negative voltage. If the target ions are positive ions, the controller 120 controls the positive and negative voltage module to provide a positive voltage.

[0095] Controller 120 is configured to set a first limit based on the input from the first human-machine interaction device; the first limit is a limit on the target ion content in the target gas flowing through ion control device 30. In other words, the limit on the target ion content in the target gas flowing through ion control device 30 is controlled by the input from the first human-machine interaction device.

[0096] For example, assuming that the input amount of the first human-computer interaction device is A, the control sets the first limit to A, that is, the ion control device 30 limits the content of target ions in the target gas flowing through itself to A.

[0097] It should be noted that the target gas has been described in detail in the above embodiments and will not be repeated here.

[0098] In a specific example, the first human-computer interaction device is a rotary key, and the size of the input is controlled by rotating the rotary key.

[0099] Optionally, the rotary key is connected to the controller 120 via a GPIO (General Purpose Input / Output). In practical applications, this includes but is not limited to this. No specific limitation is made here and it may depend on the specific situation and is within the scope of protection of this application.

[0100] It should be noted that the rotatable key is already very mature in the prior art and is not specifically limited here. It can be determined according to the specific circumstances and is within the scope of protection of this application.

[0101] In another specific example, the first human-computer interaction device is a multi-position button, and the size of the input is controlled by pressing it to different positions.

[0102] It should be noted that multi-gear buttons are already very mature in the prior art and are not specifically limited here. They can be determined according to the specific circumstances and are all within the scope of protection of this application.

[0103] The above two examples only illustrate two specific implementations of the first human-computer interaction device. In practical applications, including but not limited to these, no specific limitations are made here and it may depend on the specific situation.

[0104] In the present embodiment, the content of target ions in the target gas flowing through the ion control device 30 is restricted by the input amount of the first human-computer interaction device, so the content of target ions in the target gas flowing out of the ion calibration source is adjustable, so that the ion calibration source can be applied to different calibration scenarios, that is, to calibrate air negative ion detection devices with different negative ion content requirements. For example, air negative ion detection device A requires the negative ion content in the air to be A during calibration, while air negative ion detection device B requires the negative ion content in the air to be B during calibration. In the prior art, two test boxes with negative ion content in the air A and negative ion content in the air B are required to complete the above two calibrations. In the present embodiment, only the ion calibration source is required to complete the above two calibrations, so the ion calibration source can be applied to more calibration scenarios.

[0105] Another embodiment of the present application provides another implementation of the ion calibration source, which is suitable for the case where the flow control device 10 is also used to limit the flow rate of the target gas. Figure 8 ( Figure 8 Only in Figure 7 This embodiment, based on the embodiment provided in the previous embodiment, further includes: a second human interaction device 130.

[0106] The second manual interaction device 130 is connected to the controller 120 , and the controller 120 is connected to the flow control apparatus 10 .

[0107] The controller 120 is further configured to set a second limit based on the input of the second human-computer interaction device; the second limit is a limit on the flow rate of the target gas. In other words, the limit on the flow rate of the target gas is controlled by the input of the second human-computer interaction device.

[0108] For example, assuming that the input quantity of the second human-computer interaction device is B, the control sets the second limit to B, that is, the flow control device 10 limits the flow rate of the target gas to B.

[0109] It should be noted that the target gas has been described in detail in the above embodiments and will not be repeated here.

[0110] In a specific example, the second human-computer interaction device is a touch screen, and the size of the input is controlled by the touch screen.

[0111] Optionally, the touch screen is connected to the controller 120 via an IIC bus. In practical applications, this includes but is not limited to this. No specific limitation is made here and it may depend on the specific situation. All of this is within the scope of protection of this application.

[0112] If the flow control device 10 is a fan, the fan is connected to the controller 120 via GPIO. In practical applications, including but not limited to this, no specific limitation is made here and it can be determined according to the specific situation, all of which are within the scope of protection of this application.

[0113] It should be noted that touch screens are already very mature in the prior art and are not specifically limited here. The specific situation may vary and are all within the scope of protection of this application.

[0114] The above example only shows a specific implementation of the second human-computer interaction device. In actual applications, including but not limited to this, no specific limitation is made here and it can be determined according to specific circumstances.

[0115] If the second human-computer interaction device 130 is implemented as a touch screen or other device capable of receiving user input of setting values ​​for various parameters, the controller 120 is further configured to set a first limit based on the input amount of the second human-computer interaction device. In this case, the input amount refers to the setting value of the first limit input by the user. If the controller 120 is configured to set a second limit based on the input amount of the second human-computer interaction device, the input amount refers to the setting value of the second limit input by the user.

[0116] In this embodiment, the flow rate of the target gas is limited by the input of the second human-computer interaction device. Therefore, the flow rate of the target gas flowing out of the ion calibration source is adjustable, so that the ion calibration source can be applied to different calibration scenarios, that is, to calibrate air negative ion detection devices with different air flow rate requirements. For example, air negative ion detection device A requires an air flow rate of C during calibration, while air negative ion detection device B requires an air flow rate of D during calibration. In this embodiment, only the ion calibration source is required to complete the above two calibrations, so the ion calibration source can be applied to more calibration scenarios.

[0117] Another embodiment of the present application provides another implementation of the ion calibration source, which is applicable to the case where the ion calibration source includes a controller 120. The specific structure of this implementation can be found in Figure 9 ( Figure 9 Only in Figure 8 This embodiment, based on the above two embodiments, further includes: a heating device 140.

[0118] The heating device 140 is connected to the controller 120 .

[0119] Optionally, the heating device 140 is connected to the controller 120 via GPIO. In practical applications, including but not limited to this, no specific limitation is made here and it may depend on the specific situation and is within the scope of protection of this application.

[0120] The controller 120 is used to control the heating device 140 to heat the ion control apparatus 30 when the temperature of the environment in which the ion calibration source is located is lower than a first preset value and / or when the humidity of the environment in which the ion calibration source is located is higher than a second preset value.

[0121] If the temperature of the environment surrounding the ion calibration source is lower than the first preset value, it indicates that the temperature of the environment surrounding the ion calibration source is very low. Conversely, if the temperature of the environment surrounding the ion calibration source is not lower than the first preset value, it indicates that the temperature of the environment surrounding the ion calibration source is not very low. In actual applications, the first preset value is set based on specific parameters of the ion calibration source and is not specifically limited here.

[0122] If the humidity of the environment in which the ion calibration source is located is higher than the second preset value, it indicates that the humidity of the environment in which the ion calibration source is located is very high. Conversely, if the humidity of the environment in which the ion calibration source is located is not higher than the second preset value, it indicates that the humidity of the environment in which the ion calibration source is located is not very high. In actual applications, the second preset value is set based on the specific parameters of the ion calibration source and is not specifically limited here.

[0123] In this embodiment, the temperature of the environment in which the ion calibration source is located is lower than the first preset value, indicating that the temperature of the environment in which the ion calibration source is located is very low, and the humidity of the environment in which the ion calibration source is located is higher than the second preset value, indicating that the humidity of the environment in which the ion calibration source is located is very high. Therefore, when the temperature of the environment in which the ion calibration source is located is very low and / or the humidity of the environment in which the sub-calibration source is located is very high, the heating device 140 heats the ion control device 30, that is, heats and dehumidifies the ion control device 30, so that this embodiment can ensure that the ion control device 30 is in a suitable environment to a certain extent.

[0124] by Figure 10 Taking the ion calibration source shown in the figure as an example, the usage process of the ion calibration source is described in detail as follows:

[0125] (1) Start the ion calibration source and initialize the parameters of the ion calibration source.

[0126] (2) The gas filter device 40 is operated to filter the ions in the target gas, and ensure that the content of the ions in the target gas flowing out of the gas filter device 40 is approximately equal to zero.

[0127] (3) The flow control device 10 is operated to allow the target gas to flow through the gas filter device 40 , the ion generating device 20 , the ion control device 30 , and the output structure 50 in sequence.

[0128] (4) The content of target ions in the target gas that finally leaves the ion calibration source is set through the first manual interaction device 110 or the second manual interaction device 130 .

[0129] (5) Connect the device to be tested to the ion calibration source and start the test.

[0130] (6) Read the test data value from the device to be tested.
