Description

Technical Field

[0001] The present invention relates to the technical field of mouth-actuated toy testing, and more particularly to a mouth-actuated toy blowing and sucking tester and a testing method thereof. Background Art

[0002] As a kind of toys that are very popular among children, mouth-actuated toys are constantly innovating in design. At present, there are a variety of mouth-actuated toys, such as whistle toys and mouth-actuated launch toys (blow needle hidden weapons), etc. Different types and specifications of mouth-actuated toys are favored by more and more consumers. Due to the particularity that such toys can only be driven by children blowing or inhaling through their mouths, if there are quality problems, they contain loose structures (such as the sound beads inside the whistle), or the inhalation action causes some parts to fall off (such as the mouthpiece of the toy, etc.), and are inhaled or swallowed by children, which may cause serious suffocation risks and pose great safety hazards. Therefore, such mouth-actuated toys must undergo strict testing after production. However, the existing testing scheme usually requires inspectors to manually test the mouth-actuated toys to control the quality of the mouth-actuated toys, which makes the testing efficiency low. In the prior art, for example, a utility model patent with authorization announcement number CN204988695U discloses a mouth-actuated toy suction and blowing tester, which can automatically complete the blowing and sucking test of mouth-actuated toys. However, it is difficult to accurately simulate the blowing and sucking behavior patterns of children of different age groups, making the test results inaccurate, and there is room for improvement. Summary of the invention

[0003] An object of the present invention is to provide a mouth-actuated toy blowing and sucking tester and a testing method thereof, which can realize automatic blowing and sucking testing of mouth-actuated toys with high testing efficiency, and different modes can be selected during testing to accurately simulate the blowing and sucking behaviors of children of different age groups, thereby achieving good testing results.

[0004] To achieve these objects and other advantages of the present invention, according to one aspect of the present invention, the present invention provides a mouth-actuated toy blowing and sucking tester, comprising a housing and an inhalation test system and an alternating blowing and sucking test system fixed in the housing; Wherein, the air suction test system is provided with a cylinder, a vacuum generator and an air suction test interface which are connected in sequence; The alternating blowing and suction test system is provided with a connected cylinder and an alternating blowing and suction test interface; The free ends of the suction test interface and the alternating blowing and suction test interface are fixedly passed through the outer wall of the shell, and a pressure regulating valve and a flow regulating valve are connected between the cylinder and the vacuum generator, and between the cylinder and the alternating blowing and suction test interface.

[0005] Preferably, it also includes a control system, which includes a controller, a control panel, two pressure sensors, and two flow sensors. The controller is electrically connected to the pressure sensor, flow sensor, control panel, and cylinder, vacuum generator, pressure regulating valve and flow regulating valve respectively. The pressure sensor and flow sensor are installed at the suction test interface and the alternating blowing and suction test interface, and the control panel is installed on the outer wall of the shell.

[0006] Preferably, the controller is also connected to a power supply, and the outer side wall of the shell is provided with a switch button connected to the power supply.

[0007] Preferably, the controller sets the infant blowing module, the child blowing module and the adolescent blowing module according to the blowing behaviors of children of different age groups; wherein, The blowing and inhalation module presets the blowing pressure at the inhalation test interface and the alternating blowing and inhalation test interface to be 2.5~4kPa, the inhalation pressure to be -3.5~-2kPa, and the blowing and inhalation flow rates to be 25~35L / min; The blowing and inhalation module for children presets the blowing pressure at the inhalation test interface and the alternating blowing and inhalation test interface to be 3.5~6kPa, the inhalation pressure to be -4.5~-3kPa, and the blowing and inhalation flow rates to be 35~50L / min; The youth blowing and inhaling module presets the blowing pressure at the inhalation test interface and the alternating blowing and inhalation test interface to be 5~8kPa, the inhalation pressure to be -6~-4kPa, and the blowing and inhalation flow rates to be 50~70L / min.

[0008] The present invention also provides a testing method based on the above-mentioned mouth-actuated toy blowing and sucking tester, comprising the following steps: Step 1, turn on the switch button to connect the mouth-actuated toy to be tested with the test interface, specifically, connect the whistle toy to be tested with the alternating blowing and sucking test interface, or connect the mouth-actuated launching toy to be tested with the inhalation test interface; Step 2: According to the test requirements, one of the infant blowing and sucking module, the child blowing and sucking module and the adolescent blowing and sucking module is selected on the control panel, the cylinder is started, and the pressure regulating valve and the flow regulating valve are controlled by the controller so that the blowing pressure, the inhalation pressure, the blowing and the inhalation flow at the inhalation test interface or the alternating blowing and sucking test interface reach the preset values ​​of the corresponding module; Step 3. Repeat the blowing and sucking test and the inhalation test 10 times to check whether the mouth-actuated toy to be tested can make sounds normally and whether any parts are loose or fallen off.

[0009] Preferably, when the pressure regulating valve and the flow regulating valve are controlled by the controller in step 2, the pressure control priority is set to high and the flow control priority is set to low. First, the current pressure is monitored in real time by the pressure sensor according to the preset pressure range, and the opening of the pressure regulating valve is adjusted by the controller to adjust the pressure to reach the preset pressure range. After the pressure value stabilizes, the flow value monitored by the flow sensor is observed according to the predetermined relationship between flow and pressure. If the flow value is not within the preset flow range, the opening of the flow regulating valve is adjusted by the controller to make the flow reach the preset flow range.

[0010] Preferably, the predetermined relationship between flow and pressure is obtained by performing a large number of experimental tests on the mouth-actuated toy under different pressure and flow combinations, and recording and analyzing the variation pattern between the pressure value and the corresponding flow value.

[0011] Preferably, the relationship between the flow rate and the pressure is as follows: Q = aP 2 +c|P|+d; where Q is the flow rate, L / min; P is the pressure, kPa; a, c, d are constants.

[0019] like Figure 1 As shown (connecting pipes and lines are not shown in the figure), the present invention provides a mouth-actuated toy blowing and sucking tester, comprising a housing 100 and an inhalation test system and an alternating blowing and sucking test system fixed in the housing 100; The air suction test system is provided with a cylinder 101, a vacuum generator 102 and an air suction test interface 103 which are connected in sequence; The alternating blowing and sucking test system is provided with a connected cylinder 101 and an alternating blowing and sucking test interface 104; The free ends of the suction test interface 103 and the alternating blowing and suction test interface 104 are fixedly passed through the outer wall of the shell 100, and a pressure regulating valve 105 and a flow regulating valve 106 are connected between the cylinder 101 and the vacuum generator 102, and between the cylinder 101 and the alternating blowing and suction test interface 104.

[0020] The mouth-actuated toy blowing and sucking tester described in the above technical scheme is provided with a housing 100, and an inhalation test system and an alternating blowing and sucking test system are arranged in the housing 100 for mouth-actuated launch toys and whistle toys, respectively. The inhalation test system is provided with a cylinder 101 as a gas power source. The output end of the cylinder 101 is closely connected with a vacuum generator 102, and the vacuum generator 102 uses the principle of air pressure difference to extract the air in the cylinder 101 to form a negative pressure environment, and is connected to the inhalation test interface 103 to simulate the inhalation action of the toy. The vacuum generator 102 can be a pneumatic vacuum generator 102, which has the advantages of simple structure, small size, and easy use. The alternating blowing and sucking test system is directly driven by the cylinder 101 to simulate the alternating blowing and sucking function of the toy. In order to ensure the accuracy and flexibility of the test, a pressure regulating valve 105 and a flow regulating valve 106 are cleverly installed in both the inhalation test system and the alternating blowing and sucking test system. These two types of valves allow testers to accurately adjust the air pressure and air flow rate during the test according to actual needs to achieve the best test results. When using, first, make sure that the tester is properly connected to the power supply and is in standby mode. Then, according to the type and specification of the mouth-actuated toy to be tested, select the appropriate test interface (inhalation test interface 103 or alternating blowing and suction test interface 104) for connection. Adjust the pressure regulating valve 105 and the flow regulating valve 106 as needed to accurately control the test conditions. Start the test so that the tester will automatically execute the test procedure according to the preset parameters. During the test, the test data can be observed and recorded in real time for subsequent analysis. After the test is completed, based on the collected data, evaluate whether the blowing and suction performance of the mouth-actuated toy meets the expected standards. If necessary, adjust the test parameters for repeated testing to obtain more accurate evaluation results. This technical solution significantly shortens the test cycle and reduces labor costs through automated testing processes, while improving the accuracy and consistency of the test. By adding the pressure regulating valve 105 and the flow regulating valve 106, the tester can flexibly adjust the test conditions according to different test requirements, so as to more comprehensively evaluate the blowing and sucking performance of the mouth-actuated toy. With the help of this tester, the manufacturer can timely discover and solve the problems in the blowing and sucking performance of the mouth-actuated toy, so as to effectively improve the overall quality and market competitiveness of the product.

[0021] In another technical solution, a control system is also included, the control system includes a controller 200, a control panel 201, two pressure sensors, and two flow sensors. The controller 200 is electrically connected to the pressure sensor, the flow sensor, the control panel 201, the cylinder 101, the vacuum generator 102, the pressure regulating valve 105, and the flow regulating valve 106, respectively. The pressure sensor and the flow sensor are installed at the suction test interface 103 and the alternating blowing and sucking test interface 104, and the control panel 201 is installed on the outer wall of the shell 100. In this technical solution, the mouth-actuated toy blowing and sucking tester is also integrated with an intelligent control system, which not only improves the automation level of the test, but also greatly enhances the accuracy and controllability of the test. The control system is centered on the controller 200, which is responsible for receiving, processing and issuing instructions to coordinate the operation of the entire tester. The controller 200 is connected through a series of complex circuits to achieve seamless docking with various key components, including but not limited to pressure sensors, flow sensors, control panels 201, cylinders 101, vacuum generators 102, pressure regulating valves 105, and flow regulating valves 106. In order to monitor and accurately control the changes in air pressure and flow during the test in real time, this solution installs pressure sensors and flow sensors at the suction test interface 103 and the alternating blowing and suction test interface 104, so as to capture and feedback the air pressure and flow data at the test interface in real time, ensuring the accuracy and reliability of the test data. In addition, in order to facilitate the operation and control of the test personnel, the control system is also equipped with an intuitive and easy-to-use control panel 201. The panel is installed on the outer wall of the tester housing 100, with a simple and clear design, and includes necessary operating buttons, indicator lights, and display screens, so that the test personnel can easily set the test parameters, start / stop the test, and view the test results in real time. Through this intelligent control system, the test personnel can adjust the test conditions more conveniently and monitor the test process in real time, thereby achieving a comprehensive and accurate evaluation of the blowing and suction performance of the mouth-moving toy. At the same time, the control system also has data storage and analysis functions, which can automatically record and save the data of each test, providing strong support for subsequent data analysis and quality improvement. In short, this technical solution not only improves the efficiency and accuracy of the test, but also provides a more scientific and reliable testing method for the research and development and production of mouth-actuated toys.

[0022] In another technical solution, the controller 200 is also connected to a power supply, and a switch button connected to the power supply is provided on the outer wall of the housing 100. In this technical solution, the power supply provides power to the tester, and the switch button is provided for easy operation.

[0023] In another technical solution, the controller 200 sets the infant blowing module, the child blowing module and the adolescent blowing module according to the blowing behaviors of children of different age groups; wherein, The blowing and inhaling module for infants presets the blowing pressure at the inhalation test interface 103 and the alternating blowing and inhalation test interface 104 to be 2.5~4kPa, the inhalation pressure to be -3.5~-2kPa, and the blowing and inhalation flow rates to be 25~35L / min; The blowing and inhaling module for children presets the blowing pressure at the inhalation test interface 103 and the alternating blowing and inhalation test interface 104 to be 3.5~6kPa, the inhalation pressure to be -4.5~-3kPa, and the blowing and inhalation flow rates to be 35~50L / min; The youth blowing and inhaling module presets the blowing pressure at the inhalation test interface 103 and the alternating blowing and inhalation test interface 104 to be 5~8kPa, the inhalation pressure to be -6~-4kPa, and the blowing and inhalation flow rates to be 50~70L / min.

[0024] In this technical solution, the controller 200 is endowed with highly customized functions, which can intelligently set and adjust the test parameters according to the physiological characteristics and blowing and inhaling behavior characteristics of children of different ages. This innovative design fully considers the physiological changes in children during their growth process, ensuring that the test can truly reflect the actual blowing and inhaling ability of children of all ages when using mouth-actuated toys. Specifically, the controller 200 has three built-in blowing and inhaling modules: a toddler blowing and inhaling module, a child blowing and inhaling module, and a teenager blowing and inhaling module. Each module has fine parameter presets for the blowing and inhaling characteristics of children of the corresponding age group. Among them, the toddler blowing and inhaling module simulates young children aged 3 to 5 years old, and its preset test parameters fully consider the weaker blowing and inhaling ability and vital capacity of young children. At the inhalation test interface 103 and the alternating blowing and inhalation test interface 104, the blowing pressure is set in the range of 2.5~4kPa, and at the same time, the inhalation pressure is set to -3.5~-2kPa to simulate the natural inhalation action of young children when using mouth-actuated toys. The blowing and inhaling flow rates are controlled within the range of 25~35L / min to ensure the accuracy and reliability of the test results. The children's blowing and inhaling module simulates children aged 5 to 8 years old, and the parameter settings are adjusted accordingly. The blowing pressure is increased to 3.5~6kPa, and the inhalation pressure is set to -4.5~-3kPa to adapt to the children's gradually increasing blowing and inhaling ability. At the same time, the blowing and inhaling flow rates are also increased to 35~50L / min to ensure that the test can truly reflect the actual performance of children when using mouth-actuated toys. The adolescent blowing and inhaling module simulates children aged 9 to 15 years old. The blowing pressure is set within the range of 5~8kPa, and the inhalation pressure is set at -6~-4kPa. At the same time, the blowing and inhalation flow rates are also increased to 50~70L / min, respectively, to ensure that the test can accurately simulate the blowing and inhaling ability of children of different ages. Through this intelligent parameter setting function, a comprehensive and accurate evaluation of the blowing and inhaling performance of mouth-actuated toys is achieved. It not only improves the pertinence and accuracy of the test, but also provides a more scientific and reliable testing basis for the research and development and production of children's toys.

[0025] The present invention also provides a testing method based on the above-mentioned mouth-actuated toy blowing and sucking tester, comprising the following steps: Step 1, turn on the switch button to connect the mouth-actuated toy to be tested to the test interface, specifically, connect the whistle toy to be tested to the alternating blowing and sucking test interface 104, or connect the mouth-actuated launching toy to be tested to the inhalation test interface 103; Step 2: According to the test requirements, one of the infant blowing and sucking module, the child blowing and sucking module and the adolescent blowing and sucking module is selected at the control panel 201, the cylinder 101 is started, and the pressure regulating valve 105 and the flow regulating valve 106 are controlled by the controller 200, so that the blowing pressure, the inhalation pressure, the blowing and the inhalation flow at the inhalation test interface 103 or the alternating blowing and sucking test interface 104 reach the preset values ​​of the corresponding module; Step 3. Repeat the blowing and sucking test and the inhalation test 10 times to check whether the mouth-actuated toy to be tested can make sounds normally and whether any parts are loose or fallen off.

[0026] In the present technical scheme, the testing method based on the mouth-actuated toy blowing and sucking tester provided by the present invention not only improves the automation and intelligence level of the test, but also ensures the accuracy and reliability of the test. This method can simulate the blowing and sucking performance of children of different ages when using it, conduct a comprehensive evaluation of mouth-actuated toys, and provide strong technical support for the research and development, production and quality control of toys. Specifically, this technical scheme significantly shortens the testing cycle and reduces labor costs through an automated testing process, while improving the accuracy and consistency of the test. According to the blowing and sucking abilities of children of different age groups, multiple test modules are preset, making the test closer to actual use and improving the pertinence and practicality of the test. Through strict testing standards and repeated testing, problems with the blowing and sucking performance of mouth-actuated toys can be discovered and solved in a timely manner, thereby effectively improving the overall quality and market competitiveness of the product.

[0027] In another technical solution, when the pressure regulating valve 105 and the flow regulating valve 106 are controlled by the controller 200 in step 2, the pressure control priority is set to high and the flow control priority is set to low. First, according to the preset pressure range, the current pressure is monitored in real time by the pressure sensor, and the opening of the pressure regulating valve 105 is adjusted by the controller 200 to adjust the pressure to reach the preset pressure range. After the pressure value is stable, the flow value monitored by the flow sensor is observed according to the predetermined relationship between flow and pressure. If the flow value is not within the preset flow range, the opening of the flow regulating valve 106 is adjusted by the controller 200 to make the flow reach the preset flow range. In this technical solution, when the pressure regulating valve 105 and the flow regulating valve 106 are controlled by the controller 200, the priority order of pressure control and flow control is set to ensure the efficiency and accuracy of the test process. Specifically, the priority of pressure control is set to be higher than that of flow control. This design is based on the fact that in the blowing and sucking performance test of mouth-actuated toys, the stability and accuracy of pressure are crucial to evaluating the performance of toys. In actual operation, first, according to the preset pressure range, the controller 200 will immediately start the pressure regulation mechanism. This mechanism relies on the real-time monitoring function of the pressure sensor, which can quickly capture the actual pressure value at the current test interface and transmit these data to the controller 200. After receiving these data, the controller 200 will immediately analyze and compare to determine the gap between the current pressure and the preset pressure range. Subsequently, the controller 200 will intelligently adjust the opening of the pressure regulating valve 105 according to this gap, thereby gradually adjusting the pressure value at the test interface until it reaches the preset pressure range. Once the pressure value is stable and maintained within the preset range, the controller 200 will turn its attention to flow control. At this stage, the controller 200 will use the predetermined relationship between flow and pressure to predict and set the required flow range. This relationship is based on a large amount of experimental data and experience summary, which can ensure that under a specific pressure, the flow value can accurately reflect the blowing and sucking performance of the mouth-actuated toy. Next, the controller 200 will observe the real-time flow value monitored by the flow sensor and compare it with the preset flow range. If the flow value is not within the preset range, the controller 200 will immediately start the flow adjustment mechanism and gradually change the flow value by adjusting the opening of the flow control valve 106. This adjustment process will continue until the flow value is stable and meets the preset flow range requirements. Through this control strategy of pressure first and flow later, not only the stability and accuracy of the pressure during the test are ensured, but also the flexible adjustment of the flow can be achieved without sacrificing the test accuracy. This design not only improves the efficiency and accuracy of the test, but also provides a more scientific and reliable testing method for the research and development and production of mouth-actuated toys.In practical applications, the controller 200 adjusts the pressure regulating valve 105 and the flow regulating valve 106 dynamically and continuously to ensure that the pressure and flow values ​​during the test process can always be maintained within the preset range.

[0028] In another technical solution, the predetermined relationship between flow and pressure is obtained by conducting a large number of experimental tests on the mouth-actuated toys under different pressure and flow combinations, recording and analyzing the changing rules between the pressure value and the corresponding flow value. In this technical solution, the predetermined relationship between flow and pressure is not set out of thin air, but is a scientific conclusion drawn from a series of carefully designed experimental tests on the mouth-actuated toys under different pressure and flow combinations. During the experimental testing phase, researchers first selected a series of representative mouth-actuated toys as test objects. These toys cover different types, structures and materials to ensure the universality and applicability of the conclusions obtained. Subsequently, researchers designed a variety of different pressure and flow combination conditions for these toys, each of which represents a possible practical use scenario. During the experiment, researchers used high-precision pressure sensors and flow sensors to monitor and record the pressure and flow values ​​in each test in real time. In order to ensure the accuracy and reliability of the data, each pressure and flow combination was tested repeatedly many times, and the obtained data was strictly screened and verified. After the data collection was completed, the researchers used advanced statistical analysis and data fitting techniques to conduct in-depth analysis and exploration of the relationship between the pressure value and the corresponding flow value. They found that under different pressure and flow combinations, the flow response of the mouth-actuated toys showed certain regularity and trends. These laws are not only closely related to the structure and material properties of the toys, but also have a certain relationship with the blowing and sucking behavior and habits of children. Based on these findings, the researchers successfully established a mathematical relationship model between flow and pressure. This model can accurately describe the flow range that can be achieved by mouth-actuated toys under different pressures, as well as the trend of flow values ​​changing with pressure. The determination of this relationship provides important theoretical support and experimental basis for subsequent testing methods. Due to the wide variety and characteristics of mouth-actuated toys, in practical applications, it may be necessary to fine-tune or optimize the relationship between flow and pressure according to the characteristics and usage scenarios of the specific toys. But in general, the experimental test method and data analysis process provided by the present invention provide scientific and reliable methodological guidance for establishing this relationship.

[0029] In another technical solution, the relationship between the flow rate and the pressure is as follows: Q = aP 2 +c|P|+d; where Q is the flow rate, L / min; P is the pressure, kPa; a, c, d are constants. In this technical solution, the relationship between the flow rate and the pressure is determined by the following steps: Connect the toy to be tested to the test interface, making sure the connection is firm.

[0030] The test parameters are set on the control panel 201, including a preset pressure range and test times, etc.

[0031] The tester is started to start the test. During the test, the tester automatically adjusts the opening of the pressure regulating valve 105 and the flow regulating valve 106 to control the pressure and flow at the test interface.

[0032] The pressure and flow values ​​in each test are recorded, and the mathematical relationship between flow and pressure is calculated.

[0033] After statistical analysis of the obtained data and multiple tests and data fitting, we obtained the flow and pressure relationship Q = aP² + c|P| + d. Within a specific pressure range, the flow value shows a quadratic function trend as the pressure increases.

[0034] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
