[0026] Pump toothpaste as a new type of personal care product packaging form, in recent years in the market rapidly popular. Its through the press pump head to achieve quantitative, sanitary, convenient squeeze toothpaste, has the advantages of convenient use, good sealing, avoid pollution, etc., gradually become an important alternative to traditional toothpaste. In the overall structure of the pump toothpaste, the press pump as the core functional components, directly determines the use experience and life. Fatigue performance of the press pump refers to its ability to maintain structural integrity and functional stability under repeated press operation. In the actual use process, the user will usually press the pump head for hundreds to thousands of times, if the pump body structure design is not reasonable or the material strength is insufficient, the spring failure, seal ring damage, piston jam, leakage and other problems, leading to premature product scrap. Therefore, the durability of the press pump is one of the key indicators to measure the quality of pump toothpaste. At present, in the product development and quality control link, the test of fatigue performance of the press pump is mostly carried out by artificial simulation or general mechanical device. Artificial test method depends on the manual repeated pressing of the operator, not only labor intensity, low efficiency, and uneven force, inconsistent rhythm, leading to the lack of repeatability and objectivity of the test results, it is difficult to meet the needs of standardized detection. When using general fatigue testing machine for testing, the equipment is not designed specifically, and the structure characteristics of the pump head of the pump toothpaste (such as the height of the pump head, the pressing stroke, the required pressure range, etc.) cannot be accurately matched, resulting in unstable clamping, pressing position offset, inaccurate pressure control and other problems, affecting the test accuracy.

[0027] Therefore, it is urgent to put forward a solution that integrates mechanical stability, electrical control accuracy and man-machine interaction friendliness.

[0028] Please refer to Figs. 1-3 The embodiment provides a pump toothpaste press pump fatigue test method, which can effectively improve the above-mentioned technical problems, can automatically test the press pump, realizes the full automatic operation of the test process. The human cost is greatly reduced, and the test efficiency is improved.

[0029] The embodiment provides a pump toothpaste press pump fatigue test method, which can effectively improve the above-mentioned technical problems, can automatically test the press pump, realizes the full automatic operation of the test process. The human cost is greatly reduced, and the test efficiency is improved. S1: install the press pump to be tested 101 in the replaceable clamp 20.

[0030] S2: adjust the pressure control device 40 of the pressure reducing valve, and adjust the pressing pressure of the pressing device 30 to the preset pressure value.

[0031] In the embodiment, the pressing device 30 is a pneumatic reciprocating cylinder, and the pneumatic reciprocating cylinder has a pressing contact point, and the pressing contact point is in contact with the press pump to be tested 101.

[0032] Specifically, the pressure control device 40 includes an air source, a pressure reducing valve, an air inlet pipe, and an air outlet pipe. Both ends of the air inlet pipe and the air outlet pipe are connected to the air source and the pressing device 30, respectively. The pressure reducing valve is installed on the pressing device 30. By adjusting the pressure reducing valve of the pressure control device 40, the working air pressure of the pneumatic reciprocating cylinder is set so that the pressing pressure of the pressing device 30 is between 0.08 MPa and 0.8 MPa.

[0033] In this embodiment, the working air pressure of the pneumatic reciprocating cylinder is 0.08 MPa. In other embodiments, the working air pressure of the pneumatic reciprocating cylinder may also be 0.1 MPa, 0.2 MPa, 0.5 MPa or 0.8 MPa, and no specific limitation is made here.

[0034] Furthermore, by adjusting the pressure reducing valve of the pressure control device 40, the pressing pressure can be precisely set to a preset value (adjustable within the range of 0.08–0.8 MPa), which can simulate the actual usage force of different user groups and adapt to different types, structures, and materials of push-pump products. This adjustable pressure design enhances the versatility and applicability of the tester, making it suitable for durability verification of various pump head specifications.

[0035] During operation, the operator manually rotates the pressure reducing valve knob and observes the pressure gauge on the pressure control device 40 to adjust the compressed air pressure input to the pneumatic reciprocating cylinder, thereby changing the force applied to the pump head by the pressing device 30. Based on the above design, the operator can set the pressing pressure within the range of 0.08 MPa to 0.8 MPa according to actual needs. This range covers the mechanical strength applied by typical users when pressing the pump head, simulating the load conditions under real-world usage scenarios.

[0036] S3: Set the preset number of presses for the pressing device 30 via the control device 50.

[0037] Specifically, the preset number of presses is input through the control device 50, wherein the preset number of presses is 0 to 9999.

[0038] Furthermore, the control device 50 is equipped with a key input interface, allowing users to adjust values ​​using the up and down keys and lock settings using the confirmation key, enabling fast and accurate parameter input without the need for an external computer or complex software. This lowers the barrier to entry and makes it suitable for direct use by production line workers and technicians.

[0039] S4: The control device 50 drives the pressing device 30 to press the press pump 101 under test, so that the press pump 101 under test performs reciprocating periodic motion to perform a pressing fatigue test on the press pump 101 under test.

[0040] Specifically, when the control device 50 sends out a start signal, the execution solenoid of the control device 50 is started, the execution solenoid on-off control gas path is opened and closed, the pneumatic reciprocating cylinder is vertically downwardly applied to the pump head of the press pump to be tested 101 according to the set frequency, and a press action is completed; then the cylinder is retracted to restore the initial position, and a complete press cycle is formed. In this way, repeated loading and release of the press pump are realized, and the frequent operation process in daily use is simulated.

[0041] The press device 30 presses the press pump to be tested 101 at a preset frequency of 20 times / min.

[0042] Further, the control device 50 drives the press device 30 to press the press pump to be tested 101 in a positive counting mode or a reverse counting mode.

[0043] It should be noted that the positive counting mode (increasing from 0 to the target value) can intuitively reflect the number of completed presses; the reverse counting mode (decreasing from the preset value to 0) clearly shows the remaining test amount, which facilitates judgment of when to end, meets the psychological expectations and operation preferences of different users, and improves user experience.

[0044] S5: The single-chip microcomputer of the control device 50 counts the number of presses of the press device 30 in real time, and the control device 50 automatically stops testing when the real-time press count of the press device 30 reaches the preset press count.

[0045] Specifically, the single-chip microcomputer counts the pulse signals of the execution solenoid action signals, which can accurately record each effective press action and avoid errors caused by missed counting, incorrect counting or human intervention. When the real-time count value is equal to the preset value, the control system automatically cuts off the driving signal and stops the press action, ensuring that each group of tests is strictly completed according to the set cycle, eliminating the "under-pressing" or "over-pressing" phenomenon, improving data reliability, and stopping operation in time after completing the scheduled test, which can prevent excessive wear of the pump head, damage to the sealing structure or fatigue damage to the pneumatic components caused by continuous idle pressing, truly reflect the state of the product at the target end-of-life, and prolong the service life of the test equipment.

[0046] In this embodiment, the single-chip microcomputer has a built-in counting program, which can collect pulse signals and count the number of presses in real time every time the execution solenoid is actuated or the cylinder stroke is triggered. Specifically, during system operation, the external interrupt signal is fed back to the INT0 pin of the single-chip microcomputer through the cylinder position sensor or the execution solenoid switching state, and the counting is increased by one every time an effective pulse is received. Based on the above design, when the real-time press count reaches the preset value, the control device 50 automatically closes the execution solenoid and stops gas supply, so that the press device 30 stops acting, thereby realizing closed-loop control of the test process.

[0047] S6: During the test, the control device 50 controls the test to be temporarily interrupted in the case that the pause button is activated, and the control device 50 controls the test to continue in the case that the start button is activated again.

[0048] Specifically, in the case of abnormal conditions (such as pump head jamming, liquid leakage, clamp loosening or abnormal noise) during the test, the operator can press the pause button at any time, and the control system immediately stops the driving signal output and interrupts the pressing action, so as to avoid further damage to the tested sample or the device itself, and to ensure the safety and stability of the test environment. The pause function allows the user to perform visual inspection, replace the observation sample, supplement the toothpaste content or fine-tune the clamp position and other manual intervention operations during the test, and then resumes the original test process through the start button after completion, so as to ensure that the key test data is not lost due to temporary processing, and to improve the adaptability and flexibility of the test process.

[0049] S7: During the test, the control device 50 controls the test to be temporarily interrupted in the case that the pause button is activated, and the control device 50 controls the current pressing number of the pressing device 30 to be zeroed in the case that the clear button is activated.

[0050] Specifically, when the user completes a test without timely clearing, or decides to give up the current test and start again in the pause state, the count can be quickly reset to zero through one-key clearing, without the need to restart the system or manually modify parameters, so as to simplify the operation process and reduce the risk of misoperation.

[0051] S8: After the test is completed, the function state of the to-be-tested pressing pump 101 is detected, and if the to-be-tested pressing pump 101 normally discharges liquid, it is judged that the to-be-tested pressing pump 101 passes the fatigue test.

[0052] In this embodiment, after the pressing action is completed, the system automatically stops, and the operator removes the to-be-tested pressing pump 101 and performs function detection. The function state described herein is defined as the ability of the pressing pump to normally discharge the content after experiencing a specified number of cyclic loads. The specific detection method is to manually press the pump head several times and observe whether there is continuous and stable liquid flow. If there is no jamming, liquid leakage or jamming phenomenon, it is determined that the sample passes the fatigue test. As can be seen, the determination criterion is directly related to the core use performance of the product, and has clear technical significance and practical value.

[0053] The embodiment also provides a pump toothpaste pressing pump fatigue tester 100, which adopts the pump toothpaste pressing pump fatigue test method to perform fatigue test. The pump toothpaste pressing pump fatigue tester 100 comprises a rack 10, a pressing device 30, a replaceable clamp 20, a pressure control device 40 and a control device 50.

The replaceable clamp 20 is used to clamp a pressing pump 101 to be tested. The control device 50 is electrically connected with the pressing device 30 and the pressure control device 40.

[0054] The pump toothpaste pressing pump fatigue test method provided by the embodiment has at least the following advantages. The pump toothpaste pressing pump fatigue test method pre-sets the pressing times through the control device 50, and combines the forward counting mode, the backward counting mode and the temporary pause / continuous test function, so that the test process is more flexible and controllable. Especially in the batch detection or multi-stage evaluation scene, the test can be stopped in the middle, and the sample can be replaced and then the test can be continued, which greatly improves the operation convenience and use efficiency of the equipment.

[0055] In summary, the embodiment of the present application provides a pump toothpaste pressing pump fatigue test method and a fatigue tester.

If the pressing pump 101 to be tested normally discharges liquid, it is judged that the pressing pump 101 to be tested passes the fatigue test. During work, the pressing pump 101 to be tested is installed in the replaceable clamp 20. According to the shape size, height and mounting interface of different pump toothpastes, the corresponding clamp can be quickly replaced. The control device 50 automatically controls the periodic reciprocating pressing of the pressing device 30 on the pressing pump, replacing the traditional manual pressing mode, avoiding problems such as uneven pressing force, frequency fluctuation and fatigue interruption caused by human factors, and realizing fully automatic operation of the test process.
