A movable rod is provided inside the sleeve, with a limiting block connected to one end of the movable rod. A through-slot is formed on the top of the base plate, and an emergency stop component is provided inside the base plate.

[0004] As can be seen from the aforementioned patents, there is currently a lack of comprehensive equipment on the market capable of simultaneously and efficiently conducting airtightness and pressure resistance tests on humidifiers. Existing testing methods often suffer from low testing efficiency and insufficient accuracy, making it difficult to meet the needs of large-scale production. Therefore, there is an urgent need to develop a new type of comprehensive airtightness and pressure resistance testing platform for humidifiers. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of low testing efficiency in the existing technology of humidifiers and provides a comprehensive humidifier airtightness and pressure resistance test bench that is conducive to improving testing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A humidifier airtightness and pressure resistance comprehensive testing platform includes a frame and a humidifier base. A programmable pressure resistance tester, a PLC control box, an airtightness testing component, a pressure resistance testing component, and a bakelite template matching the humidifier base are detachably connected to the frame. The humidifier base is positioned on the bakelite template. The airtightness testing component is located above the bakelite template, and the pressure resistance testing component is located below the bakelite template. The airtightness testing component includes a cylinder electrically connected to the PLC control box, and a charging port electrically connected to the PLC control box is detachably fixed to the telescopic end of the cylinder. The humidifier base has an air inflator with a silicone head fixed to it. The air inflator is connected to the outside through the inside of the silicone head. The top of the humidifier base has a groove with an atomizing plate fixed inside. The silicone head is tightly fitted with the atomizing plate and sealed with the groove under the drive of cylinder one. The pressure resistance test assembly includes cylinder two, which is electrically connected to the PLC control box. The telescopic end of cylinder two has several probes electrically connected to the programmable pressure tester. The probes penetrate the bakelite template and are inserted into the bottom of the humidifier base. The programmable pressure tester is electrically connected to the PLC control box.

[0007] The frame is detachably connected to a programmable withstand voltage tester, a PLC control box, an airtightness testing component, a withstand voltage testing component, and a bakelite template matching the humidifier base. The humidifier base is positioned on the bakelite template. The airtightness testing component is located above the bakelite template, and the withstand voltage testing component is located below the bakelite template. The airtightness testing component includes a cylinder electrically connected to the PLC control box. An inflation head electrically connected to the PLC control box is detachably fixed to the telescopic end of the cylinder. A silicon-based... The humidifier base has a silicone head, which is connected to the outside through the inside of the silicone head. The top of the humidifier base has a groove, and an atomizing plate is fixed in the groove. The silicone head is tightly fitted with the atomizing plate and sealed with the groove under the drive of cylinder one. The pressure resistance test assembly includes cylinder two, which is electrically connected to the PLC control box. The telescopic end of cylinder two is provided with several probes that are electrically connected to the programmable pressure tester. The probes penetrate the bakelite template and are inserted into the bottom of the humidifier base. The programmable pressure tester is electrically connected to the PLC control box. The bakelite template positions the humidifier base to ensure accurate testing. During the airtightness test, cylinder one pushes the inflation head downwards, ensuring a tight fit between the silicone head and the atomizing plate. Then, gas at a certain pressure is injected into the test area through the inflation head to check for leaks. During the pressure resistance test, cylinder two pushes the probe to contact the bottom of the humidifier base for testing. This allows for simultaneous airtightness and pressure resistance testing of the humidifier using the same equipment, achieving integrated airtightness and pressure resistance testing and improving testing efficiency.

[0008] Preferably, the system also includes an air pump. A pressure regulating filter and two solenoid valves are detachably connected to the side wall of the PLC control box. The air pump is connected to the pressure regulating filter pipeline via one of the solenoid valves, allowing the PLC control box to control its start and stop. The pressure regulating filter is connected to the inflation head pipeline via the other solenoid valve, allowing the PLC control box to control the inflation. Both the pressure regulating filter and the solenoid valves are electrically connected to the PLC control box. The PLC control box, combined with the solenoid valves and pressure regulating filter, enables automated monitoring and intelligent adjustment of gas pressure and purity, facilitating automated control of airtightness testing.

[0009] Preferably, one end of the inflation head is detachably connected to the telescopic end of the cylinder, and the other end of the inflation head is provided with an inflation groove. An interface is provided on the bottom side wall of the inflation groove, and the inflation head is connected to a pressure regulating filter pipeline through the interface. The silicone head is sealed to the open end of the inflation groove, and an inflation hole communicating with the inside of the inflation groove is provided inside the silicone head. When the inflation head inflates the test area, the PLC control box controls the solenoid valve to open. The gas output from the air pump passes through the pressure regulating filter and then enters the inflation groove through the interface. Finally, gas at a certain pressure is injected into the test area through the inflation hole to perform an airtightness test on the humidifier atomizing plate.

[0010] Preferably, the bakelite mold, PLC control box, and programmable withstand voltage tester are arranged sequentially from top to bottom on the frame along the height direction, which helps to reduce the space occupied by the equipment. The frame is equipped with a withstand voltage test socket located on the side of the bakelite mold. The humidifier base has a power plug, which is connected to the withstand voltage test socket. The withstand voltage test socket is electrically connected to the PLC control box. During the airtightness test, the equipment automatically enters the withstand voltage test phase (or can be manually selected to enter). The cylinder two of the bottom withstand voltage test pushes the probe to contact the bottom of the humidifier base, connecting to the high / low voltage test via the withstand voltage test socket. The programmable withstand voltage tester gradually increases the voltage according to a set program, testing the withstand voltage performance of the bottom of the humidifier base.

[0011] Preferably, a bakelite support plate one is fixed to the top of the frame, and two bakelite support plates two are fixed to the bottom of the frame, respectively supporting the PLC control box and the programmable withstand voltage tester. The bakelite mold is detachably and fixedly connected to the bakelite support plate one. The bakelite support plate one is equipped with a start / reset button electrically connected to the PLC control box, and the start / reset button is located on the side of the bakelite mold. The withstand voltage test socket is installed on the bakelite support plate one. The bakelite support plate one, the bakelite support plate two, and the bakelite mold utilize the high mechanical strength and good insulation of bakelite, thereby improving the safety of the equipment.

[0012] Preferably, the bakelite support plate is equipped with a gantry frame. The bottom of the gantry frame is fixedly connected to the bakelite support plate, and the top of the gantry frame is detachably and fixedly connected to a bakelite isolation plate. The cylinder is detachably and fixedly connected to the bakelite isolation plate. The gantry frame is equipped with an airtightness test alarm light and a pressure resistance test alarm light, both of which are electrically connected to a PLC control box. Both the airtightness test alarm light and the pressure resistance test alarm light are located on the side of the cylinder. The airtightness test alarm light and the pressure resistance test alarm light can be set to green (pass) and red (fail) to display the test results, providing an intuitive alarm device.

[0013] Preferably, the frame is provided with a support beam, which is fixedly connected to the frame and located between the bakelite support plate and the PLC control box. A bakelite isolation plate is detachably fixedly connected to the support beam. The cylinder is detachably fixedly connected to the bakelite isolation plate. A pressure-resistant template is detachably fixed to the telescopic end of the cylinder. The probe is fixedly connected to the pressure-resistant template. Both the bakelite support plate and the bakelite template are provided with several through holes that match several probes. The bottom of the humidifier base is provided with several insertion slots that match several probes. The support beam for mounting cylinder two is located between bakelite support plate one and PLC control box. This facilitates the bottom pressure testing by having cylinder two push the probe through the through hole and insert it into the corresponding slot on the humidifier base during the pressure test. The pressure-resistant template for fixing the probe is detachably connected to the telescopic end of cylinder two, which facilitates the maintenance and replacement of the probe and is compatible with different models of humidifiers. This allows the device to be used for testing multiple models of humidifiers.

[0014] Preferably, the bottom of the bakelite template is detachably and fixedly connected to a bakelite support plate. The top of the bakelite template has a positioning groove that matches the bottom of the humidifier base. The through hole is located at the bottom of the positioning groove. A rotary switch is provided on the side wall of the humidifier base, and a slot matching the rotary switch is provided on the side wall of the open end of the positioning groove. The detachable and fixed connection between the bakelite template and the bakelite support plate facilitates the maintenance and replacement of the bakelite template and allows for compatibility with different models of humidifiers, thus enabling the device to be used for testing multiple models of humidifiers. After the rotary switch is inserted into the slot, it facilitates the positioning of the humidifier, allowing the probe to accurately contact the corresponding position on the bottom of the humidifier base.

[0015] Preferably, the bottom of the frame is equipped with several casters with brakes, which are rotatably connected to the frame. This facilitates the transfer and securing of the equipment.

[0016] Preferably, the humidifier base is positioned at the top of the bakelite mold, and the bottom of the bakelite mold is provided with several powerful magnets, which are evenly distributed around the circumference of the bakelite mold. The powerful magnets are embedded in the bakelite mold and fixedly connected to it. The bakelite support plate is provided with several magnetic conductors that match the powerful magnets. The magnetic conductors are embedded in the bakelite support plate and fixedly connected to it. The bottom of the bakelite mold is provided with two or more positioning grooves, which are located on the side of the powerful magnets. The bakelite support plate is provided with two or more positioning pins that match the positioning grooves, and the positioning pins are fixedly connected to the bakelite support plate. The bakelite template achieves rapid adsorption and positioning through the attraction between a strong magnet and a corresponding magnetic conductor. It is matched with a positioning pin and a corresponding positioning groove to ensure the positioning accuracy of the bakelite template. Disassembly only requires external force to separate it without any tools, which facilitates the rapid replacement of the bakelite template and improves replacement efficiency. This makes the device suitable for matching different models of humidifiers and can be used for testing multiple models of humidifiers.

[0017] The beneficial effects of this invention are: 1. By using the same equipment to simultaneously perform air tightness and pressure resistance tests on the humidifier, the space occupied by the equipment is reduced, and the air tightness and pressure resistance tests are integrated, thereby improving the testing efficiency. 2. Precise positioning devices and advanced detection components ensure the accuracy and reliability of test results; 3. Automated control and intuitive alarm display reduce the difficulty of manual operation, making it easier for workers on the production line to use and effectively improving production efficiency and product quality; 4. By replacing the bakelite template and the pressure resistance test probe assembly, this device can be used to test multiple models of humidifiers. Attached Figure Description
