[0030] Figure 2 It is a perspective view of a water quality analysis self-cleaning device according to some embodiments of the present specification.

[0031] Some embodiments of this specification provide a water quality analysis self-cleaning device (hereinafter referred to as "self-cleaning device"). Figure 1-Figure 2As shown, the water quality analysis self-cleaning device comprises a sensing component 10, a cleaning component 20 and a fixed housing 30 carrying the sensing component 10 and the cleaning component 20, and the cleaning component 20 comprises an air purge pipe 21, an air supply pipe 22, a cleaning switch (not shown in the figure) and an air drive component 23. The sensing component 10 is located in the fixed housing 30, one end of the air purge pipe 21 is connected to one end of the air supply pipe 22 and is located in the fixed housing 30, the other end of the air purge pipe 21 is connected to the fixed housing 30 through a second connection hole 32 on the fixed housing 30, the other end of the air supply pipe 22 is connected to the fixed housing 30 through a first connection hole 31 on the fixed housing 30, and the air drive component 23 is connected to the first connection hole 31 to blow or inhale air to the air supply pipe 22.

[0032] The sensing component 10 is a component of the self-cleaning device for detecting the water quality of the liquid to be measured (such as sewage, etc.). For example, the sensing component 10 may include a pH sensor, an ORP sensor, a DO sensor, an EC sensor, and the like.

[0033] In some embodiments, the sensing component 10 may include one or more sensors. For example, the sensing component 10 may include only one composite sensor, and one composite sensor can detect multiple water quality parameters. For another example, the sensing component 10 may include multiple single measurement sensors, each of which is used to detect one water quality parameter. As an example only, the sensing component 10 may include at least one of a pH sensor, an ORP sensor, a DO sensor, and an EC sensor. Among them, the pH sensor is used to detect the pH value of the liquid to be measured; the ORP sensor is used to detect the ORP value of the liquid to be measured; the DO sensor is used to detect the DO value of the liquid to be measured; and the EC sensor is used to detect the EC value of the liquid to be measured.

[0034] In some embodiments, the sensor component 10 may include a measuring probe 11 and a measuring body (not shown in the figure), the measuring body is located in the fixed housing 30, and the measuring probe 11 is located outside the fixed housing 30. Figure 2 As shown, the lower end of the fixed housing 30 (such as the second housing 301) has a cavity S, and the measuring probe 11 of the sensing component 10 is located in the cavity S, and is used to contact the liquid to be measured to achieve water quality detection and analysis. It can be understood that when the sensing component 10 includes multiple single-item measurement sensors, the measuring probe 11 can be an integrated body of the probes of the multiple single-item measurement sensors.

[0035] The cleaning component 20 refers to a structural component used to clean the sensor component 10 to remove dirt on the surface of the measuring probe 11. In some embodiments, the cleaning component 20 includes an air purge pipe 21, an air supply duct 22, a cleaning switch and an air drive component 23.

[0036] The cleaning switch refers to a device for controlling the opening or closing of the cleaning component. For example, the cleaning switch may include a valve, a relay, etc. In some embodiments, the cleaning switch may be automatically controlled or manually controlled. When the cleaning switch is automatically controlled, the cleaning switch may include a solenoid valve, an electromagnetic relay, etc. In some embodiments, the cleaning switch may be set at any feasible position (such as the first connection hole 31, etc.), as long as the switch control of the cleaning component 20 can be realized.

[0037] The air purge pipe 21 is a passage for blowing out or sucking air from the cleaning component 20. In some embodiments, one end of the air purge pipe 21 is connected to the second connection hole 32 on the fixed housing 30, and the other end is connected to the air supply duct 22. In some embodiments, the blowing direction or the suction direction of the air purge pipe 21 is toward the measuring probe 11 of the sensing component 10, so as to better clean the measuring probe 11.

[0038] The air supply duct 22 is a passage for the cleaning component 20 to realize air transmission. In some embodiments, one end of the air supply duct 22 is communicated with the air purge pipe 2, and the other end is communicated with the air drive component 23.

[0039] In some embodiments, the air supply duct 22 may be directly or indirectly connected to the air purge pipe 21. For example, the air supply duct 22 and the air purge pipe 21 may be connected to each other by connecting with other sections of ducts to achieve communication therebetween.

[0040] The air driving component 23 is a device or apparatus used by the cleaning component 20 to blow or inhale air. For example, the air driving component 23 may include, but is not limited to, an air pump, etc. In some embodiments, the air driving component 23 is disposed outside the fixed housing 30, and is connected to the air supply duct 22 through the first connection hole 31 on the fixed housing 30, so as to blow air or inhale air into the air supply duct 22, thereby blowing out or inhaling air through the air purge pipe 21.

[0041] In some embodiments, the air drive component 23 can operate at a preset operating power in response to a control electrical signal (such as a drive electrical signal) issued by a control component described later. The preset operating power can be manually set in advance according to actual needs. For more information about the air drive component, please refer to the relevant description below.

[0042] The fixed housing 30 is a housing of the self-cleaning device for carrying the sensing component 10 and the cleaning component 20. In some embodiments, the fixed housing 30 can be an integrally formed structure or a split structure. Figure 1-Figure 2 As shown, the fixed housing 30 includes a first housing 301 and a second housing 302 .

[0043] In some embodiments, the sensor component 10 can be disposed in the fixed housing 30 along the vertical direction, and the cleaning component 20 is located on the side of the sensor component 10. Figure 1 The X direction is indicated by the arrow.

[0044] In some embodiments, the fixed housing 30 has a first connection hole 31 and a second connection hole 32. The first connection hole 31 is used to connect with one end of the air supply duct 22, and the air drive component 23 can communicate with the air supply duct 22 through the first connection hole 31. The second connection hole 32 is used to connect with one end of the air purge pipe 21, so that air can be blown to the measuring probe 11 of the sensor component 10 through the air purge pipe 21.

[0045] In some embodiments, the structural shape of the fixed housing 30 can be determined according to the structural shapes and the setting positions of the sensing component 10 and the cleaning component 20. For example, at least a part of the structure of the fixed housing 30 (such as the first housing 301) can be columnar, so as to fix the self-cleaning device and ensure that a part of the structure of the sensing component 10 can be above the liquid level of the liquid to be measured.

[0046] In some embodiments, the sensing component 10 and the cleaning component 20 may be fixed in the fixed housing 30 in a variety of ways, such as threaded connection, welding, bonding, etc.

[0047] In some embodiments, a fixing structure 33 may be further provided on the fixed housing 30. The fixing structure 33 refers to a structure for fixing the self-cleaning device. In some embodiments, the fixing structure 33 may include at least one inner convex structure. For example, Figure 1-Figure 2 As shown, the inner convex structure can be symmetrically arranged on the peripheral side of the first shell 301. When the user uses the above-mentioned device to detect the water quality of the liquid to be measured, the inner convex structure can be hooked by an object such as a hook, so that the user can hang the self-cleaning device on an object (such as a fixed rod).

[0048] For more information about the water quality analysis self-cleaning device, please refer to the relevant description below.

[0049] In some embodiments of the present specification, the sensing component and the cleaning component are integrated into one device through a fixed housing, which can not only detect and analyze the water quality of the liquid to be measured (such as sewage), but also automatically clean the measuring probe of the sensing component in time, thereby ensuring the detection accuracy of the device. In addition, the device has a simple structure, low manufacturing cost and wide practicability.

[0050] In some embodiments, Figure 1-Figure 2As shown, the water quality analysis self-cleaning device also includes a plurality of infrared distance measuring components 40 , which are arranged around the measuring probe 11 of the sensing component 10 , and the infrared emission direction of each infrared distance measuring component 40 points to the measuring probe 11 .

[0051] The infrared distance measuring component 40 is a sensing device or apparatus that uses infrared rays as a medium to measure the distance between two objects. In some embodiments, the infrared distance measuring component 40 may include an infrared transmitter and an infrared receiver. The infrared transmitter can generate infrared rays of a certain frequency and irradiate them onto a target object (such as the measuring probe 11). The target object absorbs part of the infrared rays and reflects part of the infrared rays to the infrared receiver. Based on the time difference between the time when the infrared transmitter emits the infrared rays and the time when the infrared receiver receives the infrared rays and the propagation speed of light in a medium (such as air, water), the distance between the target object and the infrared distance measuring component 40 can be calculated.

[0052] In some embodiments, a plurality of infrared distance measuring components 40 may be arranged around the inner wall of the cavity S to measure the distance to the measuring probe 11 of the sensing component 10 .

[0053] Since the infrared distance measuring component 40 can determine the distance between the infrared distance measuring component 40 and the measuring probe 11 of the sensing component 10 according to the time difference between the emission of infrared rays and the reception of infrared rays. It can be understood that if the above time difference decreases, it indicates that the distance between the infrared distance measuring component 40 and the measuring probe 11 becomes shorter. Then, if the setting positions of the infrared distance measuring component 40 and the measuring probe 11 remain unchanged, it can be considered that this is caused by the dirt attached to the measuring probe 11. In other words, the degree of dirt on the measuring probe 11 can be determined according to the change of the time difference between the emission of infrared rays and the reception of infrared rays. For example, the smaller the time difference, the shorter the distance between the infrared distance measuring component 40 and the measuring probe 11 of the sensing component 10, indicating that the dirt layer on the measuring probe 11 is thicker (i.e., the greater the degree of dirt).

[0054] In some embodiments, the distance between any two infrared distance measuring components 40 among the plurality of infrared distance measuring components 40 is greater than a preset spacing value.

[0055] The distance between any two infrared distance measuring components 40 can be understood as the straight-line distance between any two infrared distance measuring components 40. The preset spacing value refers to a preset distance threshold. In some embodiments, the preset spacing value can be determined according to actual conditions (such as the actual number and setting position of the infrared distance measuring components 40). Figure 2 As shown, a plurality of infrared distance measuring components 40 can be arranged around the inner wall of the cavity S at equal intervals in the vertical direction.

[0056] In some embodiments, the infrared ranging component 40 may also be replaced by other devices or apparatuses, including but not limited to ultrasonic sensors, acoustic wave sensors, laser sensors, and the like.

[0057] In some embodiments of the present specification, multiple infrared ranging components are arranged around the measuring probe of the sensing component, and the distance between any two of the multiple infrared ranging components is limited, so that the multiple infrared ranging components are arranged as evenly as possible around the measuring probe, so that the measuring probe of the sensing component can be measured from multiple directions, thereby facilitating the detection of the degree of dirt on the measuring probe from multiple directions and angles in a more comprehensive manner.

[0058] In some embodiments, the water quality analysis self-cleaning device further includes a counting component (not shown in the figure), which displays statistical information in response to the detection electrical signal of the infrared ranging component 40.

[0059] The counting component is a component of the self-cleaning device for generating and displaying statistical information. In some embodiments, the counting component is connected to multiple infrared distance measuring components 40. Exemplary communication connection methods include Bluetooth, WIFI, wires, optical fibers, etc.

[0060] The detection electrical signal refers to an electrical signal generated by the infrared distance measuring component 40, which can reflect the degree of dirt on the measuring probe 11. In some embodiments, each infrared distance measuring component 40 can generate a detection electrical signal based on the time difference between the time when the infrared transmitter emits infrared rays and the time when the infrared receiver receives the infrared rays meeting a preset condition. For example, the preset condition may include that the time difference between the time when the infrared transmitter emits infrared rays and the time when the infrared receiver receives the infrared rays is less than a preset time threshold. In some embodiments, the preset time threshold can be determined according to actual needs.

[0061] The statistical information refers to the counting information generated and displayed by the counting component after counting the received detection electrical signals within a preset period of time. The preset period of time can be manually set in advance.

[0062] In some embodiments, within a preset period of time, the counting component counts once each time it receives a detection electrical signal, and the counting component can count each infrared ranging component 40 separately. For example, the self-cleaning device includes three infrared ranging components 40, which are recorded as infrared ranging component 1, infrared ranging component 2, and infrared ranging component 3. Within the preset period of time, the counting component receives the detection electrical signal emitted by the infrared ranging component 1 twice, receives the detection electrical signal emitted by the infrared ranging component 2 three times, and receives the detection electrical signal emitted by the infrared ranging component 3 twice, then the counting component can display the statistical information as (2, 3, 2).

[0063] As mentioned above, the infrared distance measuring component 40 can determine the distance between the infrared distance measuring component 40 and the measuring probe 11 of the sensor component 10 according to the time difference between the emission of infrared rays and the reception of infrared rays. It can be understood that if the above time difference decreases, it indicates that the distance between the infrared distance measuring component 40 and the measuring probe 11 becomes shorter. Then, if the setting positions of the infrared distance measuring component 40 and the measuring probe 11 remain unchanged, it can be considered that this is caused by the dirt attached to the measuring probe 11. Therefore, by counting the detection electrical signal (i.e., the statistical signal) of the infrared distance measuring component 40, the degree of dirt on the measuring probe 11 can be determined. For example, the larger the count value of each item in the statistical information or the larger the total value of multiple items, the greater the degree of dirt on the measuring probe 11.

[0064] In some embodiments, a user (such as an operation and maintenance personnel) can determine whether the measurement probe 11 needs to be cleaned based on the statistical information displayed by the counting component and according to past experience.

[0065] In some embodiments, the counting component is in communication with the control component described below. In some embodiments, the control component can generate a control electrical signal based on the statistical information generated by the counting component meeting the preset requirements and send it to the corresponding components (such as the air drive component 23, the power regulating valve 51 described below, and the vibration component) to enable the corresponding components to operate. For example, the preset requirements may include that the count value of one of the items in the statistical information is greater than a preset threshold, or the total value of multiple items in the statistical information is greater than a preset threshold, etc. For more information, please refer to the relevant description below.

[0066] In some embodiments of the present specification, a counting component is provided to count the detected electrical information of the infrared ranging component, so that the user (such as maintenance personnel) or the control component described later can quickly determine whether the measuring probe needs to be cleaned based on the statistical information. The principle of this method is simple and easy to implement.

[0067] In some embodiments, Figure 1-Figure 2 As shown, the water quality analysis self-cleaning device also includes an airflow regulating component 50 , which includes at least a power regulating valve 51 . The power regulating valve 51 is connected to the air driving component 23 to adjust the operating power of the air driving component 23 .

[0068] The air flow regulating component 50 is a component of the self-cleaning device for regulating the air flow blown out or sucked in by the air purge pipe 21. The power regulating valve 51 refers to a valve for regulating the operating power of the air drive component 23. For example, the power regulating valve 51 can be an air pump regulating valve or the like.

[0069] In some embodiments, the power regulating valve 51 can be set at any feasible position. Figure 1As shown, the power regulating valve 51 is disposed at the connection between the air driving component 23 and the first connecting hole 31 .

[0070] In some embodiments, the power regulating valve 51 can adjust the operating power of the air driving component 23 by changing the output pressure of the air driving component 23 or the like.

[0071] In some embodiments, the power regulating valve 51 can be automatically controlled or manually controlled. In some embodiments, the power regulating valve 51 can respond to a control electrical signal (such as a regulating electrical signal) sent by a control component described below to adjust the operating power of the air drive component 23.

[0072] In some embodiments of the present specification, a power regulating valve is provided to adjust the operating power of the air driving component 23, thereby changing the air flow size of the air blown out or sucked in by the air purge pipe 21, which is conducive to making the self-cleaning device more adaptable. For example, a user (such as a maintenance person) can use a larger blowing power when the sludge on the detection probe is thicker (manual observation), thereby providing a stronger cleaning effect.

[0073] Figure 3 It is a schematic diagram of the structure of the sieve plate shown in some embodiments of this specification.

[0074] In some embodiments, the air flow regulating component 50 further includes a sieve plate 52 located inside the air purge pipe 21 , and the sieve plate 52 has a preset pore size and pore density.

[0075] The sieve plate 52 is a structural member disposed in the air purge pipe 21 for changing the blowing form. Figure 3 As shown, a plurality of hole structures 521 are evenly arranged on the sieve plate 52. The structural shapes of the hole structures 521 include but are not limited to square, circular, elliptical, etc. In some embodiments, the pore size and pore density of the hole structure 521 can be manually set according to actual needs.

[0076] In some embodiments, the sieve plate 52 can be disposed at any feasible position inside the air purge pipe 21, such as the connection between the air purge pipe 21 and the second connection hole 32. In some embodiments, the sieve plate 52 can be disposed inside the air purge pipe 21 in a variety of ways. Exemplary ways may include bonding, threaded connection, clamping, etc.

[0077] It can be understood that by setting a sieve plate 52 inside the air purge tube 21, since a plurality of hole structures 521 are evenly arranged on the sieve plate 52, the air will be dispersed when it is blown out through the air purge tube 21, and the flow rate of the airflow will be increased to a certain extent, so that the fine dirt in the gaps or defects of the measuring probe 11 can be better blown away, thereby improving the cleaning effect.

[0078] Figure 4 It is a schematic diagram of the structure of the hollow baffle shown in some embodiments of this specification.

[0079] In some embodiments, Figure 1-Figure 2 , Figure 4 As shown, the airflow regulating component 50 further includes at least one hollow baffle 53 located in the air supply duct 22 , and each hollow baffle 53 is provided with a plurality of hollow shapes.

[0080] The hollow baffle 53 refers to a structural member disposed in the air supply duct 22 for changing the blowing form. In some embodiments, the number of the hollow baffles 53 may be one or more, and a plurality of hollow baffles 53 may be disposed in the air supply duct 22 at equal intervals. The hollow baffles 53 may be disposed in the air supply duct 22 in a variety of ways. Exemplary ways may include bonding, clamping, etc.

[0081] It should be noted that the hollow shape of the hollow baffle 53 can be designed according to actual needs, including but not limited to a curve, a rectangle, etc. In some embodiments, each hollow baffle 53 can be designed to have a different hollow shape, and the hollow shape of at least one hollow baffle 53 located in the air supply duct 22 can also be different.

[0082] It can be understood that before the hollow baffle 53 is provided, the air entering the air supply duct 22 flows in and out straightly, so the effect of the air purge tube is relatively fixed (because the shape of the wind blown out through the air purge tube 21 is relatively fixed), and usually only the sludge with a fixed shape on the measuring probe 11 of the sensor component 10 can be blown away. However, after the hollow baffle 53 is provided, since there are hollow baffles 53 with different hollow shapes in the air supply duct 22, the shape of the wind blown out through the air purge tube 21 can be changed differently according to the hollow baffles 53 used (for example, it may be a whole stream of wind originally, and after the hollow baffle 53 is added, it may be possible to blow out a stream of thinner wind or multiple streams of wind with different speeds, thereby enhancing the cleaning effect. Furthermore, the user can select hollow baffles 53 with different hollow shapes according to actual needs to produce wind of different shapes, so as to make the cleaning effect more adaptable.

[0083] Figure 5 It is a schematic diagram of the structure of the limiting groove shown in some embodiments of this specification.

[0084] In some embodiments, Figure 5 As shown, at least one limiting groove 221 is provided in the air supply duct 22 , and each hollow blocking piece 53 is located in one of the at least one limiting groove 221 .

[0085] The limiting groove 221 refers to a groove structure provided in the air supply duct 22 for clamping the hollow blocking piece 53 .

[0086] In some embodiments, the thickness of the limiting groove 221 is greater than the thickness of the hollow baffle 53, and the cross-sectional area of ​​the limiting groove 221 is greater than the cross-sectional area of ​​the hollow baffle 53. The water quality analysis self-cleaning device further includes a vibration component (not shown in the figure), which is located inside the air supply duct 22 and connected to the inner wall of the air supply duct 22, and is configured to continuously vibrate for a preset time after receiving the indication electrical signal sent by the cleaning component 20.

[0087] The thickness of the limit groove 221 refers to the dimension of the limit groove 221 along the axial direction of the air supply duct 22; the thickness of the hollow baffle 53 refers to the dimension of the hollow baffle 53 along the axial direction of the air supply duct 22. The cross section of the limit groove 221 refers to the cross section of the limit groove 221; the cross section of the hollow baffle 53 refers to the cross section of the hollow baffle 53, and the cross section is perpendicular to the axial direction of the air supply duct 22. In some embodiments, the axial direction of the air supply duct 22 can be represented by Figure 1 The X direction is indicated by the arrow.

[0088] The vibration component refers to a component used to make the hollow baffle 53 vibrate locally. Exemplary vibration components may include electromagnetic vibrators, etc. In some embodiments, the vibration component may be connected to the inner wall of the air supply duct 22 by bonding or the like.

[0089] The indicating electric signal refers to an electric signal sent by the cleaning component 20 and used to control the operation of the vibration component. In some embodiments, the cleaning component 20 can be connected to the counting component for communication.

[0090] In some embodiments, the cleaning component 20 can generate an indication electrical signal and send it to the vibration component based on the statistical information generated by the counting component meeting the preset indication condition. For example, the preset indication condition may include that the count value of one item in the statistical information is greater than a preset threshold, or the total value of multiple items in the statistical information is greater than a preset threshold, etc.

[0091] In some embodiments, when the vibrating component receives the instruction electric signal sent by the cleaning component 20, it starts to vibrate at a preset frequency and preset amplitude for a preset time. The preset frequency, preset amplitude and preset time can be manually set in advance according to actual needs.

[0092] In some embodiments, since the thickness of the limiting groove 221 is greater than the thickness of the hollow baffle 53, and the cross-sectional area of ​​the limiting groove 221 is greater than the cross-sectional area of ​​the hollow baffle 53, the hollow baffle 53 has a certain movable space in the limiting groove 221. When the vibrating component vibrates, the hollow baffle 53 can randomly deflect in the limiting groove 221, so that the shape of the wind blown out through the air purge pipe 21 can also change accordingly, so that a larger range of different forms of dirt can be blown away, thereby improving the cleaning effect.

[0093] Furthermore, after the self-cleaning device is put into use, it is difficult to replace the hollow baffle 53 and the maintenance cost is high. However, by providing the limit groove 221 in the air supply duct 22 and the vibrating component, the shape of the blown air can be made non-fixed on the basis of fixing the hollow baffle 53, that is, a certain degree of freedom is provided, thereby greatly increasing the adaptability of the self-cleaning device.

[0094] In some embodiments, the water quality analysis self-cleaning device further comprises a control component (not shown in the figure), which is electrically connected to the vibration component, the air drive component 23 and the power regulating valve 51. The control component is configured to control the operation of the vibration component, the air drive component 23 and the power regulating valve 51 based on the control electrical signal.

[0095] A control component is a system or component used to control the operation of multiple other components. For example, a control component can be a control center, a workbench, a processor, etc.

[0096] In some embodiments, the control component can be a separate component of the self-cleaning device, or a module or component in one or more components of the self-cleaning device. For example, the control component can be integrated in the cleaning component 20 and be a component of the cleaning component 20.

[0097] The control electric signal refers to an electric signal used to control the operation of the vibration component, the air driving component 23 and the power regulating valve 51. In some embodiments, the control electric signal may include at least one of an indication electric signal, a driving electric signal and an adjustment electric signal.

[0098] In some embodiments, the control component can generate a control electrical signal and send it to the corresponding components (such as the vibration component, the air drive component 23, and the power regulating valve 51) based on the statistical information generated by the counting component meeting the preset requirements. For example, the preset requirements may include that the count value of one of the statistical information is greater than a preset threshold, or the total value of multiple items in the statistical information is greater than a preset threshold, etc.

[0099] It is worth noting that the preset thresholds in the preset requirements that the control component should meet when generating the control electrical signal based on statistical information are different for different control electrical signals.

[0100] In some embodiments, the vibration component, the air drive component 23 and the power regulating valve 51 can perform corresponding operations based on the control electrical signal sent by the control component. For example, when the air drive component 23 receives the control electrical signal (such as the drive electrical signal) sent by the control component, it starts to operate at a preset operating power. For another example, when the vibration component receives the control electrical signal (such as the indication electrical signal) sent by the control component, it starts to vibrate at a preset frequency and preset amplitude and continues to vibrate for a preset time. For another example, when the power regulating valve 51 receives the control electrical signal (regulation electrical signal) sent by the control component, it adjusts the operating power of the air drive component 23 by changing the output pressure of the air drive component 23 and other methods.

[0101] In some embodiments, the air drive component 23 and the vibration component may start running synchronously, or the vibration component may start running after the air drive component 23 runs for a preset time, which may be determined according to actual conditions.

[0102] In some embodiments of this specification, by setting a control component and based on the statistical information of the counting component, not only can the automatic cleaning function of the device be realized, but the cleaning mode can also be adjusted according to the actual dirt situation (such as changing the wind speed), and the control method is simple.

[0103] The basic concepts have been described above. Obviously, for those skilled in the art, the above detailed disclosure is only for example and does not constitute a limitation of this specification. Although not explicitly stated here, those skilled in the art may make various modifications, improvements and corrections to this specification. Such modifications, improvements and corrections are suggested in this specification, so such modifications, improvements and corrections still belong to the spirit and scope of the exemplary embodiments of this specification.
