Description
Technical Field
[0001] This utility model relates to the field of cup manufacturing equipment technology, and specifically to a drinking spout suction flow testing device. Background Technology
[0002] A drinking cup is a type of cup with a straw or spout at the rim for direct drinking, allowing users to drink directly from the spout without fully opening the lid. To further enhance the user experience, ensuring the drinking spout remains unobstructed is a key focus of production inspection. Therefore, factories manually check the rim's patency before shipment. However, this traditional method of inspection using human visual inspection is increasingly unsuitable for large-scale industrial production, necessitating a more efficient method for measuring the rim's patency.
[0003] On the other hand, the compatibility between the flow rate at the spout and the suction power of the human mouth directly affects the user's drinking experience. Different groups of people have different suction power, such as infants, children, adults, and the elderly. In the niche market of drinking cups, meeting the drinking needs of different groups through different spout designs requires precise measurement of the spout flow rate.
[0004] In summary, a measuring device is needed to measure the flow rate of a drinking cup to meet different measurement needs. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a device for testing the suction flow rate of a drinking spout.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] A drinking spout suction flow testing device includes a vacuum pump, a suction pipeline, a testing scale, and a control center. The suction pipeline includes a nozzle, a test container, and a connecting pipe connected in sequence. The test container is hollow and placed on the testing scale. The nozzle and the connecting pipe are respectively connected to the top of the test container. The nozzle is used to connect with the drinking spout of the cup to be tested. The connecting pipe is connected to the vacuum pump. The control center is electrically connected to the vacuum pump and the testing scale. By driving the vacuum pump to generate negative pressure, the nozzle generates suction to draw the liquid in the cup to be tested into the test container. At the same time, the weight of the drawn liquid is measured by the testing scale to obtain the flow rate under the suction force.
[0008] Preferably, the device also includes a cup holder, which is mounted above the test container via a support rod. The cup holder is semi-circular, with its inner contour being an arc surface that matches the outer contour of the cup to be tested. Its bottom has a stepped surface, the maximum width of which is less than the maximum outer diameter of the cup to be tested, so that the cup to be tested is placed upside down in the cup holder and held by the stepped surface.
[0009] Preferably, the suction component further includes a vacuum pump controller and a pressure display gauge. The vacuum pump controller is connected to the vacuum pump to adjust the pressure value of the vacuum pump. The pressure display gauge is located on the control center and connected to the vacuum pump through a second connecting air pipe to provide real-time feedback on the negative pressure value in the suction line.
[0010] Preferably, the control center is equipped with a timing controller to limit the start-up time of the vacuum pump.
[0011] Preferably, the control center is equipped with green and red indicator lights to display different test results.
[0012] Preferably, the control center has a built-in buzzer to emit different sounds depending on whether the green or red indicator light is lit.
[0013] Preferably, the inner capacity of the test container is greater than the maximum liquid capacity in the cup to be tested.
[0014] Preferably, the test container is transparent and has scale values marked on it.
[0015] Preferably, the control center is equipped with an emergency stop button.
[0016] The beneficial effects of this utility model are mainly reflected in:
[0017] 1. A vacuum pump and suction pipe are used to simulate the suction force generated when a user drinks water. A test tank is set up to collect the liquid in the test cup. The flow rate per unit time is directly tested by weighing to determine whether the drinking spout is unobstructed and whether the flow rate meets the requirements. One test solves multiple problems.
[0018] 2. Set up a vacuum pump controller to control the vacuum pump to provide different suction forces, and then test whether it can be used smoothly by different users;
[0019] 3. The test tank is set to a transparent tank with scale values to facilitate visual observation and quick identification of the flow rate per unit time. This makes it convenient for users to conduct spot checks and directly check whether the test results of the test scale are correct, avoiding misjudgments caused by malfunctions of the test scale.

[0024] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.
[0025] In the description of the solution, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.
[0026] like Figures 1 to 3 As shown, this utility model discloses a drinking spout suction flow testing device, including a vacuum pump 1, a suction pipe, a testing scale 2, and a control center 3. The suction pipe includes a suction nozzle 401, a test container 402, and a connecting pipe 403 connected in sequence. The test container 402 is hollow inside and is placed on the testing scale 2. The suction nozzle 401 and the connecting pipe 403 are respectively connected to the top of the test container 402. The suction nozzle 401 is used to connect with the drinking spout 501 of the cup 5 to be tested. The connecting pipe 403 is connected to the vacuum pump 1. The control center 3 is electrically connected to the vacuum pump 1 and the testing scale 2. By driving the vacuum pump 1 to generate negative pressure, the suction nozzle 401 generates suction to draw the liquid in the cup 5 to be tested into the test container 402. At the same time, the weight of the drawn liquid is measured by the testing scale 2 to obtain the flow rate under the suction.
[0027] This solution uses the vacuum pump 1 and the suction pipe to simulate the suction force generated when a user drinks water. The test tank 402 is set up to hold the liquid in the test cup 5, which enhances the authenticity of the test. The flow rate per unit time is directly tested by weighing, which can determine whether the drinking spout 501 is unobstructed and whether the flow rate of the drinking spout 501 meets the requirements. One test solves multiple problems and enhances practicality.
[0028] Furthermore, the system also includes a cup holder 6, which is mounted above the test container 1 via a support rod 601. The cup holder 6 is semi-circular in shape to provide a certain degree of deformation elasticity, allowing it to hold test cups 5 of different outer diameters. The inner contour of the cup holder 6 is an arc surface that matches the outer contour of the test cup 5, and its bottom has a stepped surface 602. The maximum width of the stepped surface 602 is smaller than the maximum outer diameter of the test cup 5, allowing the test cup 5 to be placed upside down within the cup holder 6 and held by the stepped surface 602. Inverting the test cup 5 further conforms to the user's actual drinking state, improving the authenticity of the test, and shortening the required length of the spout 401, thus saving costs.
[0029] The suction component also includes a vacuum pump controller 404 and a pressure display 405. The vacuum pump controller 404 is connected to the vacuum pump 1 to adjust the pressure value of the vacuum pump 1. The pressure display 405 is located on the control center 3 and connected to the vacuum pump 1 via a second connecting air pipe 406 to provide real-time feedback on the negative pressure value in the suction line. The vacuum pump controller 404 can control the pressure value of the vacuum pump 1 to provide different suction forces, simulating different users' suction levels, and thus detecting whether users with different suction levels can use the product smoothly, improving the product's usability and user experience.
[0030] The control center 3 is equipped with a timing controller 7 to limit the start-up time of the vacuum pump 1. The timing controller 7 is used to set the single detection time to detect the flow rate of the drinking port 501 within a specified unit time. The specific single detection duration can be set according to different detection needs to improve the overall flexibility of the detection equipment.
[0031] The control center 3 is equipped with a green indicator light 8 and a red indicator light 9 to display different test results. Specifically, the control center 3 calculates the volume of the liquid being drawn out based on the weight and density of the liquid, thus determining the flow rate. For ease of calculation, the liquid in the test cup 5 is preferably purified water. The control center 3 compares the obtained flow rate with the expected value. When the flow rate is greater than or equal to the expected value, the flow rate of the drinking spout 501 is considered qualified, and the green indicator light 8 illuminates; otherwise, the red indicator light 9 illuminates.
[0032] Furthermore, the control center 3 has a built-in buzzer that emits different sounds depending on whether the green indicator light 8 or the red indicator light 9 is lit. When the green indicator light 8 is lit, the buzzer emits a "beep" sound to indicate that the test result is qualified; when the red indicator light 9 is lit, the buzzer emits a long "beep" sound to indicate that the test result is unqualified.
[0033] To prevent the liquid in the test container 402 from flowing into the connecting air pipe 403, the inner capacity of the test container 402 is greater than the maximum liquid capacity in the cup to be tested 5.
[0034] Preferably, the test container 402 is transparent and has scale markings on it. This design allows for visual inspection, facilitating random checks by users and enabling direct verification of the accuracy of the test results from the testing scale 2, thus preventing misjudgments due to scale 2 malfunction.
[0035] The control center 3 is equipped with an emergency stop button 10, which is electrically connected to the power supply inside the control center 3. When an abnormality is detected during the detection process, pressing the emergency stop button 10 will quickly cut off the power and stop the operation of the vacuum pump 1.
[0036] In addition, a main switch is provided on the back of the control center 3.
[0037] The working process of this equipment is as follows:
[0038] S1. Place the test cup 5 containing purified water upside down into the cup holder 6;
[0039] S2. Connect the air nozzle 401 to the drinking spout 501;
[0040] S3. Turn on the main switch, turn on the control center 3, and set the vacuum pump controller 404 and the timing controller 7 according to the test requirements;
[0041] S4. Control center 3 starts vacuum pump 1 to generate suction;
[0042] S5. The liquid in the cup to be tested 5 is drawn into the test container 402, and at the same time, the scale 2 weighs the test container 402 in real time.
[0043] S6. The control center 3 calculates the flow rate based on the weighing structure of the detection scale 2, compares it with the expected value, and then outputs the detection structure.
[0044] S7. When the test result is qualified, the green indicator light 8 will light up and emit a "beep" sound; when the test result is unqualified, the red indicator light 9 will light up and emit a continuous long "beep" sound.
[0045] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0046] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
