[0001] The utility model relates to the technical field of hookahs, in particular to an air tightness testing device for a hookah valve. Background Art

[0002] The hookah, also known as "water pipe" or "hookah pipe", is a traditional smoking tool that originated in the Middle East and South Asia. Its basic structure includes a container (usually made of glass) for storing water, a pipe and a bowl for heating tobacco. The hookah cools and purifies the tobacco smoke through the filtering effect of water. When used, the smoke flows through the water and is then inhaled. It is often used in social occasions and is usually paired with special tobacco mixtures, such as tobacco with fruit flavors.

[0003] During assembly, the installation and sealing of the hookah valve is particularly important, as it determines whether the hookah can be used normally. Conventional installations are sealed by means of rubber plugs or threaded tightening, and their sealing needs to be pressure tested to meet the needs of use. The conventional test is inflation, but this inflation method does not have good characteristics to display, so its sealing needs to be tested. Utility Model Content

[0028] See also Figure 1 , Figure 2 as well as Figure 3 When the hookah 3 is in use, the installation and sealing of the hookah valve is particularly important, which is related to whether the hookah 3 can be used normally. The conventional installation is sealed by a rubber plug or a threaded tightening method, and its sealing needs to be pressure tested to meet the needs of use. The conventional test is inflation, but this inflation method does not have good characteristics to display, so it is necessary to test its sealing. Based on this, the present application provides an airtightness test device for a hookah valve, including a test component 1 for sealing test and a hookah 3 installed in the test component 1.

[0029] The test assembly 1 includes a loading cylinder 11 and an insertion area 16 disposed at the inner bottom of the loading cylinder 11. A limiting assembly 4 is disposed in the insertion area 16 for limiting the hookah 3.

[0030] An extension platform 14 is arranged outside the loading cylinder 11, and a pressurizing assembly 2 is mounted on the extension platform 14 for matching the hookah 3 with the testing assembly 1 to test the sealing performance.

[0031] The loading cylinder 11 is the main part of the test device, which is usually a cylindrical structure and is used to accommodate the hookah 3 and perform a sealing test. A plug-in area 16 is provided at the bottom of the inner side thereof, and the plug-in area 16 is designed to ensure the stable placement of the hookah 3.

[0032] The insertion area 16 is a special structure inside the loading cylinder 11, which is usually designed as a groove or a raised engagement area for engaging the bottom or valve position of the hookah 3. A limit assembly 4 is arranged in the insertion area 16 for fixing the hookah 3 to prevent it from moving or floating during the test.

[0033] The design of the stopper assembly 4 is to ensure that the hookah 3 can be stably fixed in the insertion area 16 of the loading cylinder 11 during the test to prevent it from floating or moving. Common stopper assemblies 4 include spring clips, adjustment screws or rubber sealing rings 13, etc., which can be adjusted and fixed according to the specific shape of the hookah 3.

[0034] The extension platform 14 is a platform installed outside the loading cylinder 11, and its function is to provide a stable foundation to support the installation and operation of the charging assembly 2. The design of the extension platform 14 needs to be strong enough to withstand the pressure changes during the charging process.

[0035] The charging assembly 2 is mounted on the extension platform 14 and is used to charge the hookah 3 in the loading cylinder 11 with gas. The charging assembly 2 may include a pressure pump, a pressure gauge and a gas input port. By adjusting the charging assembly 2, the pressure of the gas injected into the hookah 3 can be controlled, and the change of the gas pressure during the test can be monitored.

[0036] Implementation steps:

[0037] The hookah 3 is placed in the insertion area 16 of the loading cylinder 11 and fixed in position by the limiting assembly 4 .

[0038] Place the loading cylinder 11 on the extension platform 14 and ensure that the charging assembly 2 is well connected to the loading cylinder 11 .

[0039] Start the charging assembly 2, fill the hookah 3 with gas, and monitor the internal pressure change through the pressure gauge.

[0040] Observe the pressure maintenance of the hookah 3 after charging. If the sealing performance of the hookah 3 is good, the pressure will remain stable. If the sealing performance is poor, the gas will escape through the leakage point, causing the pressure to drop.

[0041] The air tightness of the hookah 3 is determined according to the test results, and adjustments or repairs are made when necessary.

[0042] By combining liquid immersion and pressurization, the air tightness of the hookah 3 can be detected more accurately, avoiding the errors that may occur in a simple inflation test.

[0043] The setting of the limiting component 4 can effectively fix the hookah 3, prevent inaccurate testing due to buoyancy or movement during the test, and ensure the reliability of the test results.

[0044] Through this design, the tester can quickly perform the air tightness test without manually adjusting the position of the hookah 3 or repeatedly checking, thereby improving the test efficiency.

[0045] The device can be suitable for hookahs 3 of different types and sizes, and the limiting component 4 can be adjusted according to actual needs, thereby increasing the adaptability of the device.

[0046] The integrated design of the charging component 2 and the testing component 1 simplifies the operation process and makes the sealing test more convenient and intuitive.

[0047] See also Figure 1 , Figure 2 as well as Figure 3 The inner side of the loading cylinder 11 is filled with liquid for displaying the pressure test, and a base 15 is provided at the bottom thereof.

[0048] A through hole is formed on one side of the loading cylinder 11 , and a connecting pipe 12 is installed inside the through hole via a sealing ring 13 . The other end of the connecting pipe 12 extends to the inside of the loading cylinder 11 .

[0049] The inner side of the loading cylinder 11 is filled with liquid (such as water or other suitable liquid). The main function of the liquid is to indicate gas leakage by observing the generation of bubbles on the surface of the liquid during the pressure test. During pressure charging, if the hookah 3 has a leak, gas bubbles will emerge from the leak point of the hookah 3, and obvious bubbles will appear on the surface of the liquid, thereby helping the tester to intuitively identify the sealing problem.

[0050] A through hole is provided on one side of the loading cylinder 11, and the through hole is used to install the connecting pipe 12. The position and size of the through hole need to match the connecting pipe 12 to ensure the stability and sealing of the connection.

[0051] The inner side of the through hole is provided with a connecting pipe 12 via a sealing ring 13. The sealing ring 13 is used to prevent liquid from leaking through the through hole during the pressure test, thereby ensuring the accuracy of the test process.

[0052] One end of the connecting tube 12 extends into the interior of the loading cylinder 11, and the other end is used to connect to the charging assembly 2. The design of the connecting tube 12 needs to ensure that the gas can be effectively transmitted to the interior of the hookah 3 without causing gas leakage due to poor connection. The connecting tube 12 also needs to be resistant to high pressure to cope with the pressure that may be generated during the test.

[0053] Implementation steps:

[0054] Before testing, a proper amount of liquid is filled into the loading cylinder 11. The liquid should cover the outside of the hookah 3 so that the bubble situation can be accurately observed during the pressure charging process.

[0055] The connecting pipe 12 is installed to the inner side of the loading cylinder 11 through the through hole, and the sealing ring 13 is ensured to be well sealed to prevent liquid leakage.

[0056] The hookah 3 is placed in the insertion area 16 of the loading cylinder 11 and fixed in position by the limiting assembly 4 to ensure that it does not move during the test.

[0057] The other end of the connecting tube 12 is connected to the charging assembly 2 , and the charging assembly 2 is started to charge the hookah 3 with gas.

[0058] During the charging process, observe the surface of the liquid in the loading cylinder 11 to check whether bubbles are generated. The appearance of bubbles indicates that there is an airtightness problem in the hookah 3, and the number and position of the bubbles help to locate the leakage point.

[0059] Record the test results based on the observed bubbles, analyze the tightness of the hookah 3, and make necessary adjustments or repairs.

[0060] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The charging assembly 2 includes an air compressor 22 , and a docking conduit 21 is installed at an interface of the air compressor 22 , and one end of the docking conduit 21 is adapted to one end of the connecting pipe 12 .

[0061] The other end of the connecting pipe 12 is provided with a second docking conduit 23 , and the other end of the second docking conduit 23 is adapted to the valve opening of the hookah 3 .

[0062] The limiting assembly 4 includes one or more groups of blocks 41 , each group of blocks 41 has at least two blocks and are symmetrically arranged.

[0063] A fixed distance is maintained between the two groups of card blocks 41 , and an elastic member 42 is installed at the fixed distance to control the expansion and closing of the card blocks 41 .

[0064] The inner side of the clamping block 41 is arranged in an arc shape, and the inner side of the clamping block 41 is adapted to the outer side of the hookah 3 .

[0065] The core of the charging assembly 2 is the air compressor 22 , which is a device capable of generating high-pressure gas for charging the hookah 3 with gas.

[0066] A docking conduit 21 is installed at the interface of the air compressor 22, which is adapted to one end of the connecting pipe 12 and is used to connect the air compressor 22 and the inside of the loading cylinder 11.

[0067] The other end of the connecting pipe 12 is provided with a second docking conduit 23 , which is adapted to the valve opening of the hookah 3 and is used to introduce high-pressure gas into the interior of the hookah 3 .

[0068] The limiting assembly 4 is composed of one or more groups of blocks 41, each group having at least two blocks 41, which are symmetrically arranged. The inner side of the blocks 41 is arc-shaped, which fits the outer side of the hookah 3 to ensure that the hookah 3 can be firmly fixed in the loading cylinder 11.

[0069] A fixed distance is maintained between the two groups of blocks 41, and an elastic member 42, such as a spring or a rubber band, is installed at the fixed distance. The elastic member 42 is used to control the expansion and closing of the blocks 41, so that the hookah 3 is more convenient to fix and take out.

[0070] Implementation steps:

[0071] The hookah 3 is placed in the insertion area 16 of the loading cylinder 11, and then fixed in position by the limiting assembly 4. The clamping block 41 is closed under the push of the elastic member 42, and the hookah 3 is firmly clamped.

[0072] One end of the docking conduit 1 21 is connected to one end of the connecting pipe 12, and the other end is connected to the docking conduit 2 23, and finally docked with the valve of the hookah 3. Ensure that all connection points are well sealed.

[0073] The air compressor 22 is turned on to fill the hookah 3 with high pressure gas. At the same time, the surface of the liquid in the loading cylinder 11 is observed to check whether bubbles are generated.

[0074] The test results are recorded according to the situation of the bubbles, and the sealing performance of the hookah 3 is analyzed.

[0075] If the test result is not satisfactory, make necessary adjustments or repairs. After completion, turn off the air compressor 22, release the pressure and take out the hookah 3.

[0076] Using the air compressor 22 as the pressure-charging component 2 can realize rapid filling of gas, thereby improving the automation level of the test.

[0077] The design of the docking conduit 1 21 and the docking conduit 2 23 ensures the stability of the connecting pipe 12 and reduces the risk of gas leakage.

[0078] The design of the clamping block 41 of the limiting assembly 4 makes it more convenient to fix and remove the hookah 3, thereby reducing the labor intensity of the operator.

[0079] The arc-shaped design of the clamping block 41 can adapt to hookahs 3 of different shapes, thereby improving the adaptability of the device.

[0080] The installation of the elastic member 42 ensures that the clamping block 41 can be properly adjusted, thereby avoiding potential dangers caused by over-tightening or over-loosening.

[0081] The improvement of the pressurizing assembly 2 and the limiting assembly 4 improves the efficiency of the entire testing process, reduces the testing time, and improves production efficiency.

For those skilled in the art, the present invention may have various modifications and variations.
