Detailed implementation manners

[0036] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments.

[0037] An e-cigarette airtightness testing device proposed in this embodiment, such as Figure 1 , Figure 5 and Figure 6As shown in the figure, it includes an operating table 1. A mounting frame 2 is fixedly connected to the top of the operating table 1. There is a lifting seat 3 above the operating table 1. The mounting frame 2 is fixedly installed with a first hydraulic telescopic rod 4. The telescopic end of the first hydraulic telescopic rod 4 is fixedly connected to the top of the lifting seat 3. The lifting seat 3 is equipped with several groups of clamping and lifting structures for clamping the top end of the e-cigarette shell 8. There is a carrier plate 5 between the lifting seat 3 and the operating table 1;

[0038] A number of positioning sleeves 6 for limiting the position of the e-cigarette shell 8 penetrate through the carrier plate 5, and the positioning sleeves 6 are fixedly connected to the carrier plate 5. Two support plates 7 are in contact with the bottom of the positioning sleeve 6. The carrier plate 5 is equipped with an elastic support mechanism for supporting the support plate 7. The operating table 1 is equipped with a translation correction mechanism for driving the carrier plate 5 to move horizontally. The top of the operating table 1 is provided with a sealing air inlet unit for sealing the bottom end of the e-cigarette shell 8; An external air pump is connected to the sealing air inlet unit through a pressure valve. The carrier plate 5 is driven to move by the translation correction mechanism so that a number of corresponding e-cigarette shells 8 move below the lifting seat 3. The lifting seat 3 is driven to move downward by the first hydraulic telescopic rod 4. The lifting seat 3 presses the top end of the e-cigarette shell 8. The lifting seat 3 pushes the e-cigarette shell 8 downward, and the support plate 7 no longer supports the bottom of the e-cigarette shell 8. The bottom end of the e-cigarette shell 8 is supported and sealed by the sealing air inlet unit. The top end of the e-cigarette shell 8 is sealed by the lifting seat 3. The external air pump is started. When the value of the pressure valve does not reach the preset value, the air tightness of the e-cigarette shell 8 does not meet the requirements. When the value of the pressure valve exceeds the preset value, the air tightness of the e-cigarette shell 8 meets the requirements. When the air tightness test of the e-cigarette shell 8 is completed, the top end of the e-cigarette shell 8 is clamped and fixed by the clamping and lifting structure. The lifting seat 3 and the e-cigarette shell 8 are driven to move upward by the first hydraulic telescopic rod 4 so that the bottom end of the e-cigarette shell 8 no longer contacts the sealing air inlet unit. The horizontal position of the bottom of the e-cigarette shell 8 is higher than the top horizontal position of the support plate 7, and the support plate 7 is driven to reset to the initial position by the elastic support mechanism, so that the support plate 7 supports the e-cigarette shell 8, making the e-cigarette shell 8 at the initial height. The air tightness test method of the e-cigarette shell 8 is changed. It is not necessary to dry the e-cigarette shell 8. At the same time, it can be directly understood whether the air tightness of the e-cigarette shell 8 meets the requirements, which is convenient for actual use.

[0039] In some optional specific embodiments, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the sealed air intake unit includes a number of support platforms 10 fixedly installed on the top of the operation table 1. The number of support platforms 10 is the same as that of the clamping and lifting structures. A sealing seat 9 is fixedly connected above the support platform 10. An accommodation hole 11 for accommodating the bottom end of the e-cigarette housing 8 is provided on the sealing seat 9. An air intake chamber 12 for injecting air into the accommodation hole 11 is provided on the top of the support platform 10. The support platform 10 is equipped with an intake pipe 13 adapted to the air intake chamber 12. A number of sealing gaskets 49 are fixedly connected to the bottom of the lifting seat 3, and the number of sealing gaskets 49 is the same as that of the sealing seats 9. The sealing seat 9 is fixedly installed with a sealing ring 50 located below the accommodation hole 11, and the bottom of the sealing ring 50 is fixedly connected to the top of the support platform 10. Each clamping and lifting structure includes two clamping plates 14 arranged below the lifting seat 3. A movable seat 15 is respectively provided on the side of adjacent two clamping plates 14 away from each other, and the movable seat 15 and the clamping plate 14 are fixedly connected by a first connecting plate 16. Support columns 17 are respectively fixedly connected to both ends of the movable seat 15. The mounting frame 2 is fixedly installed with a fixed frame 18. Support blocks 19 are respectively provided at both ends of the movable seat 15. A support frame 20 is provided above the support block 19, and both the support block 19 and the support frame 20 are fixedly connected to the fixed frame 18. Inclined surfaces adapted to the support columns 17 are provided on both the support block 19 and the support frame 20. The lifting seat 3 is equipped with a magnetic attraction reset unit adapted to the movable seat 15. The magnetic attraction reset unit includes two iron frames 25 fixedly installed on the top of the movable seat 15. Two guide columns 21 penetrate through the movable seat 15. One end of the guide column 21 and the bottom of the lifting seat 3 are fixedly connected by a second connecting plate 22. The other end of the guide column 21 is fixedly connected with a fixed disk 23. The movable seat 15 and the second connecting plate 22 are connected by a first spring 24, and the fixed disk 23 is located on the side of the movable seat 15 away from the clamping plate 14. The second connecting plate 22 is fixedly installed with a first magnet block 26 in contact with the iron frame 25;

[0040] When the lifting seat 3 pushes the e-cigarette housing 8 downward so that the bottom end of the e-cigarette housing 8 is inserted into the receiving hole 11, the bottom of the sealing gasket 49 abuts against the top end of the e-cigarette housing 8, and the bottom end of the e-cigarette housing 8 abuts against the top of the sealing ring 50, thereby sealing both ends of the e-cigarette housing 8. The external air pump is connected through the pressure valve and the intake pipe 13. The external air pump is started, and air is injected into the intake chamber 12 through the intake pipe 13. The air enters the e-cigarette housing 8 through the intake chamber 12. When the first hydraulic telescopic rod 4 drives the lifting seat 3 to move downward, the lifting seat 3 drives the movable seat 15 and the support column 17 to move downward synchronously through the second connecting plate 22 and the guiding column 21. The support column 17 slides on the inclined surface of the support block 19, and the support block 19 pushes the support column 17 and the movable seat 15 to move towards the second connecting plate 22. The adjacent two clamping plates 14 move closer to each other, and the first spring 24 is in a compressed state. When the bottom end of the e-cigarette housing 8 abuts against the sealing gasket 49, the iron frame 25 contacts the first magnet block 26. At this time, the movable seat 15 is fixed relative to the second connecting plate 22 and the lifting seat 3, and at this time, the movable seat 15 drives the clamping plate 14 to abut against the e-cigarette housing 8 through the first connecting plate 16, and the adjacent two clamping plates 14 clamp the e-cigarette housing 8. When the lifting seat 3 moves upward, the lifting seat 3 drives the e-cigarette housing 8 to move upward synchronously through the clamping plate 14. When the horizontal position of the bottom of the e-cigarette housing 8 is higher than the horizontal position of the top of the support plate 7, as the lifting seat 3 continues to move upward, the lifting seat 3 drives the support column 17 to slide on the inclined surface of the support frame 20 through the movable seat 15, and the support frame 20 pushes the support column 17 and the movable seat 15 to move in the reverse direction, so that the iron frame 25 no longer magnetically attracts the first magnet block 26. The first spring 24 pushes the movable seat 15 and the clamping plate 14 to move away from the e-cigarette housing 8. The movable seat 15 abuts against the fixed disk 23, and the movable seat 15 and the clamping plate 14 are reset to the initial position relative to the lifting seat 3. The adjacent two clamping plates 14 no longer clamp the e-cigarette housing 8, and the adjacent two support plates 7 can support the bottom of the e-cigarette housing 8. When the translation correction mechanism drives the carrier plate 5 to move, the next corresponding e-cigarette housing 8 can move between the adjacent two clamping plates 14.

[0041] In some optional specific embodiments, such as Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, the elastic support mechanism includes support blocks 28 respectively arranged on the far sides of two adjacent pallets 7. The support blocks 28 are provided with inclined surfaces adapted to the pallets 7, and the tops of the support blocks 28 are fixedly connected to the bottom of the load-carrying plate 5. Support bars 29 are fixedly connected to both sides of the pallet 7 respectively. A lifting frame 27 is sleeved outside the support block 28. The lifting frame 27 is of a U-shaped structure. First guiding grooves 30 are respectively formed on the inner walls of both sides of the lifting frame 27. A first guiding block 31 is fixedly connected to the side of the support bar 29 away from the pallet 7, and the first guiding block 31 is located in the corresponding first guiding groove 30. A first accommodating groove 32 is formed on the support bar 29. A second spring 33 is arranged in the first accommodating groove 32. Both ends of the second spring 33 are fixedly connected to the inner wall of the first accommodating groove 32 and the lifting frame 27 respectively. The load-carrying plate 5 is equipped with a reset unit adapted to the lifting frame 27. The reset unit includes a movable plate 34 arranged above the lifting frame 27, and the movable plate 34 is located above the load-carrying plate 5. The movable plate 34 and the lifting frame 27 are connected by a third connecting plate 35, and the third connecting plate 35 penetrates through the load-carrying plate 5. The bottom of the movable plate 34 and the top of the load-carrying plate 5 are connected by a number of third springs 36. The translation correction mechanism includes two movable frames 37 arranged below the load-carrying plate 5. Second accommodating grooves 38 are respectively formed at both ends of the movable frame 37. Second magnet blocks 39 are fixedly connected in the second accommodating grooves 38. An iron block 40 is in contact with the top of the second magnet block 39, and the top of the iron block 40 is fixedly connected to the bottom of the load-carrying plate 5. A number of positioning holes 48 arranged in sequence are formed on the load-carrying plate 5. A number of positioning columns 47 adapted to the positioning holes 48 are fixedly connected to the bottom of the lifting seat 3, and the bottom end of the positioning column 47 is of a frustum-shaped structure. The operating platform 1 is equipped with an elastic translation member adapted to the movable frame 37. The elastic translation member includes two mounting plates 42 fixedly installed on the operating platform 1. A second hydraulic telescopic rod 43 is fixedly installed on the mounting plate 42. The telescopic end of the second hydraulic telescopic rod 43 is fixedly connected to a movable block 41. A second guiding groove 45 is formed on the bottom of the movable frame 37. A second guiding block 44 is slidably arranged in the second guiding groove 45, and both sides of the second guiding block 44 are fixedly connected to the inner wall of the second guiding groove 45 by fourth springs 46 respectively. The tops of the two movable blocks 41 are respectively fixedly connected to the bottoms of the two second guiding blocks 44;

[0042] The tester places the carrier plate 5 with several e-cigarette housings 8 above the movable frame 37, and the iron block 40 at the bottom of the carrier plate 5 is inserted into the second receiving groove 38. The iron block 40 and the second magnet block 39 are magnetically attracted to fix the carrier plate 5 relative to the movable frame 37. The second hydraulic telescopic rod 43 drives the movable block 41, the second guide block 44 and the movable frame 37 to move relative to the operating table 1, so that a group of several corresponding e-cigarette housings 8 move below the lifting seat 3. The first hydraulic telescopic rod 4 drives the lifting seat 3 to move downward, and the lifting seat 3 drives the bottom end of the positioning column 47 to insert into the corresponding positioning hole 48. The bottom end of the positioning column 47 is of a frustum-shaped structure. When there is a deviation in the positions of the carrier plate 5 and the positioning hole 48, the bottom end of the positioning column 47 pushes the positioning hole 48, the carrier plate 5 and the movable frame 37 to slide relative to the second guide block 44 and the movable block 41, and the fourth spring 46 deforms. The positions of the carrier plate 5 and the e-cigarette housing 8 are corrected through the positioning column 47 to ensure that the e-cigarette housing 8 is directly below the lifting seat 3. As the lifting seat 3 continues to move downward, the positioning column 47 penetrates the corresponding positioning hole 48, and the lifting seat 3 pushes the corresponding e-cigarette housing 8 downward. The e-cigarette housing 8 pushes the support plate 7, the support bar 29 and the lifting frame 27 downward. The lifting frame 27 drives the movable plate 34 to move downward through the third connecting plate 35. The third spring 36 is in a compressed state, and the second spring 33 is in a stretched state in the initial state. The second spring 33 exerts a pulling force on the support bar 29 and the support plate 7, so that the end of the support plate 7 abuts against the inclined surface of the support block 28. When the e-cigarette housing 8 pushes the support plate 7 downward, the second spring 33 pulls the support bar 29 and the support plate 7 to move, so that the end of the support plate 7 slides on the inclined surface of the support block 28, and the first guide block 31 slides in the first guide groove 30. When the support plate 7 descends to a preset position, the support plate 7 slides relative to the support block 28 to a preset position, and the top of the support plate 7 no longer supports the bottom of the e-cigarette housing 8. The e-cigarette housing 8 slides past the side of the support plate 7 until the sealed air intake unit supports and seals the e-cigarette housing 8. When the lifting seat 3 drives the e-cigarette housing 8 to move upward through the clamping and lifting structure, so that the horizontal position of the bottom of the e-cigarette housing 8 is higher than the horizontal position of the top of the support plate 7, as the e-cigarette housing 8 continues to move upward, the third spring 36 pushes the movable plate 34, the third connecting plate 35 and the lifting frame 27 to move upward, so that the support plate 7 moves upward synchronously with the e-cigarette housing 8, and the end of the support plate 7 slides reversely on the inclined surface of the support block 28. The deformation degree of the second spring 33 increases, and the adjacent ends of the two support plates 7 move to the bottom of the e-cigarette housing 8. Finally, the tops of the support plate 7 and the lifting frame 27 both contact the bottom of the carrier plate 5, and the support plate 7 and the lifting frame 27 reset to the initial height. The e-cigarette housing 8 can be supported by the two adjacent support plates 7.

[0043] This embodiment also provides an e-cigarette airtightness test method, including the e-cigarette airtightness test device as described above, and includes the following steps:

[0044] Step 1: The tester inserts the bottom ends of several e-cigarette shells 8 to be tested into the positioning sleeve 6, supports the bottom of the e-cigarette shell 8 through the support plate 7, and connects the external air pump through the pressure valve and the sealed air intake unit;

[0045] Step 2: Drive the carrier plate 5 to move through the translation correction mechanism, so that a group of several corresponding e-cigarette shells 8 move below the lifting seat 3. Drive the lifting seat 3 to move downward through the first hydraulic telescopic rod 4. The lifting seat 3 pushes the e-cigarette shell 8 downward, and the support plate 7 no longer supports the bottom of the e-cigarette shell 8. Support and seal the bottom end of the e-cigarette shell 8 through the sealed air intake unit, and seal the top end of the e-cigarette shell 8 with the lifting seat 3;

[0046] Step 3: Start the external air pump. When the value of the pressure valve does not reach the preset value, the airtightness of the e-cigarette shell 8 does not meet the requirements. When the value of the pressure valve exceeds the preset value, the airtightness of the e-cigarette shell 8 meets the requirements;

[0047] Step 4: After the test of the e-cigarette shell 8 is completed, clamp and fix the top end of the e-cigarette shell 8 through the clamping and lifting structure, and drive the lifting seat 3 and the e-cigarette shell 8 to move upward through the first hydraulic telescopic rod 4, so that the bottom end of the e-cigarette shell 8 no longer contacts the sealed air intake unit;

[0048] Step 5: When the horizontal position of the bottom of the e-cigarette shell 8 is higher than the top horizontal position of the support plate 7 and the support plate 7 is driven to return to the initial position through the elastic support mechanism, the support plate 7 supports the e-cigarette shell 8, so that the e-cigarette shell 8 is at the initial height, and return to execute Step 2 until all the e-cigarette shells 8 are tested.

[0049] Working principle: The tester inserts the bottom ends of several e-cigarette shells 8 to be tested into the positioning sleeve 6, and supports the bottom of the e-cigarette shell 8 through the support plate 7. The external air pump is connected through the pressure valve and the sealed air intake unit. The carrier plate 5 is driven to move by the translation correction mechanism, so that a group of several corresponding e-cigarette shells 8 move below the lifting seat 3. The lifting seat 3 is driven to move downward by the first hydraulic telescopic rod 4. The lifting seat 3 presses the top end of the e-cigarette shell 8, and the lifting seat 3 pushes the e-cigarette shell 8 downward. The support plate 7 no longer supports the bottom of the e-cigarette shell 8. The bottom end of the e-cigarette shell 8 is supported and sealed through the sealed air intake unit. The lifting seat 3 seals the top end of the e-cigarette shell 8. The external air pump is started. When the value of the pressure valve does not reach the preset value, the airtightness of the e-cigarette shell 8 does not meet the requirements. When the value of the pressure valve exceeds the preset value, the airtightness of the e-cigarette shell 8 meets the requirements. After the e-cigarette shell 8 is tested, the top end of the e-cigarette shell 8 is clamped and fixed through the clamping and lifting structure. The lifting seat 3 and the e-cigarette shell 8 are driven to move upward by the first hydraulic telescopic rod 4, so that the bottom end of the e-cigarette shell 8 no longer contacts the sealed air intake unit. The horizontal position of the bottom of the e-cigarette shell 8 is higher than the horizontal position of the top of the support plate 7, and the support plate 7 is driven to return to the initial position through the elastic support mechanism, so that the support plate 7 supports the e-cigarette shell 8, making the e-cigarette shell 8 at the initial height. The carrier plate 5 is driven to move relative to the operation table 1 through the translation correction mechanism, so that the next group of several untested e-cigarette shells 8 move below the lifting seat 3, and the test of the next group of e-cigarette shells 8 can be started. The airtightness test method of the e-cigarette shell 8 is changed. It is not necessary to dry the e-cigarette shell 8, and at the same time, it can be directly understood whether the airtightness of the e-cigarette shell 8 meets the requirements, which is convenient for actual use;

[0050] When the lifting seat 3 pushes the e-cigarette housing 8 downward so that the bottom end of the e-cigarette housing 8 is inserted into the receiving hole 11, the bottom of the sealing gasket 49 abuts against the top end of the e-cigarette housing 8, and the bottom end of the e-cigarette housing 8 abuts against the top of the sealing ring 50, thereby sealing both ends of the e-cigarette housing 8. The external air pump is connected to the intake chamber 12 through a pressure valve and an intake pipe 13. The external air pump is started, and air is injected into the intake chamber 12 through the intake pipe 13. The air enters the e-cigarette housing 8 through the intake chamber 12. When the first hydraulic telescopic rod 4 drives the lifting seat 3 to move downward, the lifting seat 3 drives the movable seat 15 and the support column 17 to move downward synchronously through the second connecting plate 22 and the guide column 21. The support column 17 slides on the inclined surface of the support block 19, and the support block 19 pushes the support column 17 and the movable seat 15 to move toward the second connecting plate 22. The adjacent two clamping plates 14 move closer to each other, and the first spring 24 is in a compressed state. When the bottom end of the e-cigarette housing 8 abuts against the sealing gasket 49, the iron frame 25 contacts the first magnet block 26. At this time, the movable seat 15 is fixed relative to the second connecting plate 22 and the lifting seat 3, and at this time, the movable seat 15 drives the clamping plate 14 to abut against the e-cigarette housing 8 through the first connecting plate 16. The adjacent two clamping plates 14 clamp the e-cigarette housing 8. When the lifting seat 3 moves upward, the lifting seat 3 drives the e-cigarette housing 8 to move upward synchronously through the clamping plate 14. When the horizontal position of the bottom of the e-cigarette housing 8 is higher than the horizontal position of the top of the support plate 7, as the lifting seat 3 continues to move upward, the lifting seat 3 drives the support column 17 to slide on the inclined surface of the support frame 20 through the movable seat 15. The support frame 20 pushes the support column 17 and the movable seat 15 to move in the reverse direction so that the iron frame 25 no longer magnetically attracts the first magnet block 26. The first spring 24 pushes the movable seat 15 and the clamping plate 14 to move away from the e-cigarette housing 8. The movable seat 15 abuts against the fixed disk 23, and the movable seat 15 and the clamping plate 14 are reset to the initial position relative to the lifting seat 3. The adjacent two clamping plates 14 no longer clamp the e-cigarette housing 8, and the adjacent two support plates 7 can support the bottom of the e-cigarette housing 8. When the translation correction mechanism drives the carrier plate 5 to move, the next corresponding e-cigarette housing 8 can move between the adjacent two clamping plates 14;

[0051] The tester places the carrier plate 5 with several e-cigarette housings 8 on top of the movable frame 37, and the iron block 40 at the bottom of the carrier plate 5 is inserted into the second receiving groove 38. The iron block 40 and the second magnet block 39 are magnetically attracted to fix the carrier plate 5 relative to the movable frame 37. The second hydraulic telescopic rod 43 drives the movable block 41, the second guide block 44 and the movable frame 37 to move relative to the operation table 1, so that a group of several corresponding e-cigarette housings 8 move below the lifting seat 3. The first hydraulic telescopic rod 4 drives the lifting seat 3 to move downward. The lifting seat 3 drives the bottom end of the positioning column 47 to insert into the corresponding positioning hole 48. The bottom end of the positioning column 47 is a frustum-shaped structure. When there is a deviation in the positions of the carrier plate 5 and the positioning hole 48, the bottom end of the positioning column 47 pushes the positioning hole 48, the carrier plate 5 and the movable frame 37 to slide relative to the second guide block 44 and the movable block 41, and the fourth spring 46 deforms. The positions of the carrier plate 5 and the e-cigarette housing 8 are corrected by the positioning column 47 to ensure that the e-cigarette housing 8 is directly below the lifting seat 3. As the lifting seat 3 continues to move downward, the positioning column 47 passes through the corresponding positioning hole 48. The lifting seat 3 pushes the corresponding e-cigarette housing 8 downward. The e-cigarette housing 8 pushes the support plate 7, the support bar 29 and the lifting frame 27 downward. The lifting frame 27 drives the movable plate 34 to move downward through the third connecting plate 35. The third spring 36 is in a compressed state, and the second spring 33 is in a stretched state in the initial state. The second spring 33 applies a pulling force to the support bar 29 and the support plate 7, so that the end of the support plate 7 abuts against the inclined surface of the support block 28. When the e-cigarette housing 8 pushes the support plate 7 downward, the second spring 33 pulls the support bar 29 and the support plate 7 to move, so that the end of the support plate 7 slides on the inclined surface of the support block 28, and the first guide block 31 slides in the first guide groove 30. When the support plate 7 descends to the preset position, the support plate 7 slides relative to the support block 28 to the preset position, and the top of the support plate 7 no longer supports the bottom of the e-cigarette housing 8. The e-cigarette housing 8 slides past the side of the support plate 7 until the sealed air intake unit supports and seals the e-cigarette housing 8. When the lifting seat 3 drives the e-cigarette housing 8 to move upward through the clamping and lifting structure, so that the horizontal position of the bottom of the e-cigarette housing 8 is higher than the horizontal position of the top of the support plate 7, as the e-cigarette housing 8 continues to move upward, the third spring 36 pushes the movable plate 34, the third connecting plate 35 and the lifting frame 27 to move upward, so that the support plate 7 moves upward synchronously with the e-cigarette housing 8, and the end of the support plate 7 slides reversely on the inclined surface of the support block 28. The deformation degree of the second spring 33 increases, and the adjacent ends of the two support plates 7 move to the bottom of the e-cigarette housing 8. Finally, the tops of the support plate 7 and the lifting frame 27 both contact the bottom of the carrier plate 5, and the support plate 7 and the lifting frame 27 reset to the initial height. The e-cigarette housing 8 can be supported by the two adjacent support plates 7.
