Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0028] like Figures 1 to 6 As shown, the flushing bag air inspection device of the present invention includes: a frame 1, on which is disposed a detection platform 2 and a pressure plate 3 that can be raised and lowered above the detection platform 2; wherein, the detection platform 2 is formed with a detection window 21 for the flushing bag to pass through, the bottom surface of the pressure plate 3 is disposed with a fixed shaft 4 and an expandable first expansion member 5 is formed around the fixed shaft 4, the first expansion member 5 is coaxial with the detection window 21 and can extend into the detection window 21 when not expanded; an air pressure detection member, which is disposed on the bottom surface of the fixed shaft 4.

[0029] See also Figure 1 、 Figure 2 The bottom surface of the detection platform 2 is at a certain height distance from the frame 1, so that after the flushing bag is placed in the detection window 21, it can expand at the bottom of the detection platform 2, thereby realizing air tightness detection. A vertically penetrating detection window 21 is formed on the detection platform 2. The detection window 21 can be circular, rectangular or other shapes. The specific shape can be selected according to the type of flushing bag; the pressing plate 3 is located directly above the detection platform 2, and the pressing plate 3 is configured to be able to move toward the detection platform 2 or move away from the detection platform 2.

[0030] See also Figure 4 The bottom surface of the pressure plate 3 is equipped with a fixed shaft 4, which is coaxial with the detection window 21 and can extend into the detection window 21. A first expandable member 5 is arranged around the outer periphery of the fixed shaft 4. The horizontal straight-line distance between the outer wall of the first expandable member 5 and the inner wall of the detection window 21 can be 0.5-5 mm. When the first expandable member 5 is not expanded, it can extend into the detection window 21. It should be noted that the bottom surface of the fixed shaft 4 is equipped with an air pressure detection member and an air inlet 6, wherein the air pressure detection member can be an air pressure detection sensor. The air inlet 6 is connected to an external first air inlet device via a pipeline. It should also be noted that the first expandable member 5 is connected to an external second air inlet device via a pipeline.

[0031] When the flushing bag needs to be tested for air tightness, the opening of the flushing bag is first placed on the first expansion member 5. Thereafter, a small amount of air is introduced into the first expansion member 5 by using the second air inlet device, thereby causing the first expansion member 5 to expand and seal the opening of the flushing bag. Thereafter, the pressure plate 3 is controlled to move downward so that the lower portion of the flushing bag passes through the detection window 21 and the opening of the flushing bag is located within the detection window 21. The second air inlet device is then used to introduce air into the first expansion member 5. The first expansion member 5 continues to expand to press the flushing bag against the inner wall of the detection window 21, thereby sealing the opening of the flushing bag. Thereafter, the first air inlet device is used to press the flushing bag against the inner wall of the detection window 21 to seal the flushing bag opening. The air inlet 6 opened below the fixed axis 4 is used to supply air to the flushing bag. When the air pressure detection component detects that the air pressure in the flushing bag is at a certain threshold, the air supply to the inside of the flushing bag is stopped. After waiting for a period of time, if the value detected by the air pressure detection component is still within the threshold range, the flushing bag is a qualified product. The present application effectively avoids the subsequent drying step of the flushing bag by replacing the water inspection method with the air inspection method of the flushing bag, thereby improving the production rate of the flushing bag. At the same time, combined with the method of tightening the flushing bag opening with the first expansion member 5, it can effectively ensure the accuracy of the air tightness detection of the flushing bag, and has practicality.

[0032] In one or more embodiments, a plurality of rubber skeletons 7 are evenly arranged in the first expandable member 5 around the central axis of the first expandable member 5 .

[0033] See also Figure 5 、 Figure 6 , expansion gaps are formed between adjacent rubber skeletons 7, and in the first expandable member 5, several expansion gaps are interconnected; the expansion angle of the first expandable member 5 is limited by the rubber skeleton 7, which can effectively ensure the uniformity of the expansion of the first expandable member 5 and reduce the possibility of the opening of the flushing bag being damaged by the expansion.

[0034] In one or more embodiments, the detection platform 2 is configured with a second expansion member 8 around the detection window 21, and the inner side surface of the second expansion member 8 is tangent to the inner wall of the detection window 21; the detection platform 2 forms a stepped groove around the detection window 21, and the second expansion member 8 is located in the stepped groove.

[0035] See also Figure 2 、 Figure 4 The second expansion member 8 is connected to the third air inlet device via a pipeline. When the flushing bag needs to be tested for air tightness, the flushing bag is pushed into the testing window 21 by the pressing plate 3. The third air inlet device then allows air to enter the second expansion member 8. The second expansion member 8 expands and tightens the outer wall of the flushing bag opening, further improving the sealing effect of the flushing bag opening and ensuring the accuracy of the flushing bag air tightness test.

[0036] When the detection is completed, the second air intake device is controlled to exhaust the first expansion member 5 and the third air intake device is controlled to exhaust the second expansion member 8. At this time, the opening of the flushing bag is no longer under pressure, and the gas inside the flushing bag is discharged through the opening of the flushing bag. Then the flushing bag is pulled downward out of the detection window 21 from under the detection platform 2. It has the characteristics of simple structure, convenient operation, and practicality.

[0037] In one or more embodiments, the first expandable member 5 and the second expandable member 8 are both made of rubber. This ensures the expansion capacity of the first expandable member 5 and the second expandable member 8. Furthermore, the rubber material is relatively soft, which effectively reduces damage to the flushing bag when the first expandable member 5 and the second expandable member 8 come into contact with the flushing bag, thereby ensuring safety during the airtightness testing of the flushing bag.

[0038] In one or more embodiments, the detection window 21 has a rounded corner structure. This arrangement can further reduce the risk of the detection platform 2 scratching the flushing bag.

[0039] In one or more embodiments, at least one set of compression structures is configured on the bottom surface of the detection platform 2 outside the detection window 21, and the compression structure can extend toward the detection window 21 to compress the inflated flushing bag; the compression structure includes at least a pushing member 91 and an elastic member 92, and the pushing member 91 is connected to the bottom surface of the detection platform 2 with the aid of the elastic member 92. With the aid of the elastic force of the elastic member 92, the pushing member 91 is pushed horizontally into the area defined by the detection window 21.

[0040] See also Figure 2 、 Figure 4In the initial state, with the help of the elastic force of the elastic member 92, the pushing member 91 is pushed to be tangent to the inner wall of the detection window 21 on the side facing the detection window 21; when the flushing bag is tested for air tightness, the flushing bag expands, and the flushing bag squeezes the pushing member 91, and the elastic member 92 is in a compressed state. When the air tightness test of the flushing bag is completed, under the action of the elastic member 92, the pushing member 91 squeezes the flushing bag, so that the gas inside the flushing bag can be quickly discharged through its opening, making it easier for the staff to pull the flushing bag out from the lower part of the detection window 21.

[0041] In a possible embodiment, the pushing member 91 is made of rubber material. Through this arrangement, the damage of the pushing member 91 to the flushing bag can be further reduced, and the safety of the flushing bag during air tightness testing can be guaranteed.

[0042] In one or more embodiments, elastic wires are disposed in both the first expandable member 5 and the second expandable member 8. It should be noted that the elastic wires can assist in resetting the first expandable member 5 and the second expandable member 8, thereby extending their service life.

[0043] In one or more embodiments, the frame 1 is provided with a support frame 10, and the support frame 10 is provided with a driving device 11 connected to the top surface of the pressing plate 3, and the driving device 11 can drive the pressing plate 3 to move up and down in the vertical direction. Figure 2 The driving device 11 can be a driving cylinder. When working, the position of the pressing plate 3 in the height direction can be controlled by controlling the extension or retraction of the extended shaft end of the driving cylinder. The structure is simple and the operation is convenient.

Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model.
