Description

Technical Field

[0001] This utility model relates to the field of pipe tampers, and more particularly to magnetic elastic pipe tampers. Background Technology

[0002] Pipe tampers originated from the need for proper tobacco combustion. To ensure complete combustion and a smoother flavor, a tool was needed to compress the expanding tobacco fibers. Pipe tampers can be made from various materials, including wood, bone, mother-of-pearl, brass, and silver. The main function of a pipe tamper is to compress the tobacco, making it more compact and ensuring a continuous and stable burn. Compressing the tobacco also prevents the pipe from going out during smoking.

[0003] When using a pipe tamper, the force should be moderate to avoid pressing the tobacco too firmly, which makes smoking difficult. In the authorized Chinese utility model patent "Announcement No.: CN202068920U, Name: Grinding Pipe Tamper", the pressing surface of the tamper is designed with a rough, non-smooth surface. This allows the tamper to grind the surface of the tobacco while pressing it firmly, creating a uniform combustion layer. This ensures stable burning of the tobacco without damaging the pipe and prevents the tobacco from going out. However, in the above application and existing technology, the force applied to the tobacco by the tamper is controlled solely by hand. Since tobacco requires relatively little force, it is difficult for the hand to achieve precise control. This can lead to over- or under-pressing of the tobacco when pressing it into the pipe, resulting in uneven combustion. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the defect that the manual force application in the prior art is prone to uneven tobacco combustion, and to provide a magnetic elastic pipe press rod.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This utility model provides a magnetic elastic pipe press bar, including a tobacco press head, one end of which is inserted into one end of a movable press column, and an inner holding sleeve is slidably connected to the outside of the movable press column;

[0007] The movable pressure column is connected to a connecting drive shaft at one end away from the tobacco pressure head. A first magnet is connected to one end of the connecting drive shaft, and a second magnet is provided at the other end of the first magnet away from the connecting drive shaft.

[0008] A plug is provided on the side of the second magnet block away from the first magnet block, and the plug is threaded to the inside of one end of the inner sleeve.

[0009] In this technical solution, the principle of like poles repulsion between the first and second magnets is utilized. When a person applies force to the sleeve with their hand, the first and second magnets apply force to the movable pressure column, thereby applying force to the tobacco pressure head. This allows for automatic application of force to the tobacco in the pipe, which can dissipate the force applied by the person's hand. This enables precise control of the force applied to the tobacco, so as to ensure complete combustion of the tobacco.

[0010] Preferably, the S-end of the first magnet block and the S-end of the second magnet block are close to each other.

[0011] In this technical solution, the principle of like poles repelling each other is used to achieve precise pressure on the tobacco by utilizing the first and second magnet blocks.

[0012] Preferably, the area inside the inner sleeve is divided into, from bottom to top, a pressure column movable area, a connecting area, a magnetic elastic area, and an installation area;

[0013] The movable pressure column is located within the movable area of ​​the pressure column, the first magnet block and the second magnet block are located within the magnetic elastic area, and the plug is located within the installation area.

[0014] In this technical solution, the first magnet block and the second magnet block move within the magnetic elastic region.

[0015] Preferably, a limiting groove is provided on the side of the movable pressure column, and an insertion groove is provided at the end of the movable pressure column away from the tobacco pressure head, and one end of the connecting drive shaft is inserted into the movable pressure column through the insertion groove.

[0016] In this technical solution, the time limit bead moves within the limit groove.

[0017] Preferably, the movable pressure column has an arc-shaped groove on its side, and the inner sleeve has a plurality of through holes arranged in a ring array on its side.

[0018] A limiting bead is provided inside the through hole, and the diameter of the arc-shaped groove is larger than the diameter of the limiting bead.

[0019] Preferably, the plug is provided with a reminder component, which includes a warning light and a contact switch;

[0020] The warning light is connected to the side of the plug away from the second magnet, and a contact switch is connected to the side of the plug closer to the second magnet.

[0021] In this technical solution, when a person applies significant force, the reminder component illuminates to provide a warning.

[0022] Preferably, the warning light and the contact switch are electrically connected.

[0023] In this technical solution, the warning light illuminates when the second magnet contacts the contact switch.

[0024] Preferably, the end of the plug away from the second magnet block has an installation groove, and the warning light is connected to the plug through the installation groove.

[0025] In this technical solution, a mounting slot is used to connect the warning light.

[0026] Preferably, a plug-in interface is provided on one side of the tobacco press head, and one end of the movable press column is plugged into the tobacco press head through the plug-in interface.

[0027] In this technical solution, a plug-in interface is used to connect the tobacco press head and the movable press column.

[0028] Preferably, an outer protective tube is detachably sleeved on the outside of the inner sleeve.

[0029] In this technical solution, an outer protective tube is used to protect the pipe tamping rod when it is not in use.

[0030] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0031] The positive and progressive effects of this utility model are as follows:

[0032] This invention utilizes the principle of like poles repulsion between the first and second magnets. When a person applies force to the sleeve with their hand, the first and second magnets apply force to the movable pressure column, thereby applying force to the tobacco pressure head. This allows for automatic application of force to the tobacco in the pipe, thus dissipating the force applied by the person's hand. This enables precise control of the force applied to the tobacco, ensuring complete combustion of the tobacco.

[0033] Meanwhile, the reminder component can deactivate when the user applies excessive force, causing the reminder component to light up and remind the user to reduce the force. The presence of the reminder component makes it easier for the user to apply force to the tobacco. Attached Figure Description

[0055] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0056] Figures 1 to 10 The diagram shown is a structural schematic of an embodiment of the magnetic elastic pipe tamper of this invention. The magnetic elastic pipe tamper includes a tobacco tamper head 1, one end of which is inserted into one end of a movable tamper 2, and an inner retaining sleeve 3 is slidably connected to the outside of the movable tamper 2.

[0057] The movable pressure column 2 is connected to a connecting drive shaft 4 at one end away from the tobacco pressure head 1. A first magnet block 5 is connected to one end of the connecting drive shaft 4, and a second magnet block 6 is provided at the end of the first magnet block 5 away from the connecting drive shaft 4.

[0058] A plug 7 is provided on the side of the second magnet block 6 away from the first magnet block 5, and the plug 7 is threaded to the inner side of one end of the inner sleeve 3.

[0059] In this technical solution, the principle of like poles repulsion between the first magnet 5 and the second magnet 6 is utilized. When a person applies force to the sleeve 3 with their hand, the first magnet 5 and the second magnet 6 apply force to the movable pressure column 2, thereby applying force to the tobacco pressure head 1. This allows for automatic application of force to the tobacco in the pipe, which can release the force applied by the person's hand and enable precise control of the force applied to the tobacco to ensure complete combustion of the tobacco.

[0060] The S-end of the first magnet block 5 and the S-end of the second magnet block 6 are close to each other.

[0061] Alternatively, the N-end of the first magnet block 5 and the N-end of the second magnet block 6 may be close to each other.

[0062] In this technical solution, the principle of like poles repulsion between the first magnet 5 and the second magnet 6 is used to achieve precise pressure on the tobacco.

[0063] The area inside the inner sleeve 3 is divided into, from bottom to top, a pressure column movable area 31, a connecting area 32, a magnetic elastic area 33, and an installation area 34.

[0064] The movable pressure column 2 is located in the pressure column movable area 31, the first magnet block 5 and the second magnet block 6 are located in the magnetic elastic area 33, and the plug 7 is located in the installation area 34.

[0065] In this technical solution, the first magnet block 5 and the second magnet block 6 move within the magnetic elastic region 33.

[0066] The movable pressure column 2 has a limiting groove 21 on its side, and the end of the movable pressure column 2 away from the tobacco pressure head 1 has an insertion groove 22. One end of the connecting drive shaft 4 is inserted into the movable pressure column 2 through the insertion groove 22.

[0067] In this technical solution, the time limit bead 8 moves within the limit groove 21.

[0068] The movable pressure column 2 has an arc-shaped groove 23 on its side, and the inner sleeve 3 has a plurality of through holes 35 arranged in a ring array on its side.

[0069] A limiting bead 8 is provided inside the through hole 35, and the diameter of the arc groove 23 is larger than the diameter of the limiting bead 8.

[0070] In use, the person holds the inner sleeve 3, then contacts the tobacco press head 1 with the tobacco and presses the inner sleeve 3 downward. At this time, the tobacco press head 1 moves upward under the action of the tobacco, thereby driving the movable press column 2 and the connecting drive shaft 4 to move in the same direction, which in turn drives the first magnet block 5 to move in the same direction. At this time, under the mutual repulsion of the first magnet block 5 and the second magnet block 6, the second magnet block 6 moves upward. During the process of the mutual repulsion of the first magnet block 5 and the second magnet block 6, the force is applied to the person's hand to release the force, and the tobacco press head 1 is used to apply appropriate force to the tobacco. Repeating this process multiple times completes the pressing of tobacco into the pipe, so as to facilitate the complete combustion of the tobacco.

[0071] During use, the limiting bead 8 moves within the limiting groove 21, the first magnet block 5 and the second magnet block 6 move within the magnetic elastic region 33, the movable pressure column 2 moves within the pressure column movement region 31, and the connecting drive shaft 4 moves within the connecting region 32.

[0072] A reminder component 9 is provided at the plug 7, and the reminder component 9 includes a warning light 91 and a contact switch 92;

[0073] The warning light 91 is connected to the side of the plug 7 away from the second magnet 6, and the side of the plug 7 close to the second magnet 6 is connected to a contact switch 92.

[0074] In this technical solution, when a person applies significant force, the reminder component 9 illuminates to provide a warning.

[0075] The warning light 91 and the contact switch 92 are electrically connected.

[0076] In this technical solution, when the second magnet 6 contacts the contact switch 92, the warning light 91 illuminates.

[0077] The end of the plug 7 away from the second magnet block 6 has an installation groove, and the warning light 91 is connected to the plug 7 through the installation groove.

[0078] In this technical solution, the warning light 91 is connected using a mounting slot.

[0079] When a person applies a large force to the inner sleeve 3, the second magnet 6 moves upward and contacts the contact switch 92, thereby controlling the warning light 91 to turn on and illuminate, thus reminding the person.

[0080] The tobacco press head 1 has an insertion interface on one side, and one end of the movable press column 2 is inserted into the tobacco press head 1 through the insertion interface.

[0081] In this technical solution, a plug-in interface is used to connect the tobacco press head 1 and the movable press column 2.

[0082] The outer protective tube 10 is detachably sleeved on the outside of the inner sleeve 3.

[0083] In this technical solution, the outer protective tube 10 is used to protect the pipe tamping rod when it is not in use.

[0084] The elastic modulus (k) of tobacco during combustion is a complex parameter because the physical properties of tobacco change during combustion.

[0085] During combustion, the tobacco undergoes the following changes:

[0086] Moisture evaporation: The moisture in the tobacco evaporates, causing it to become brittle;

[0087] Thermal decomposition: The organic matter in tobacco undergoes thermal decomposition, producing gases and ash;

[0088] Structural damage: Combustion causes the structure of tobacco to gradually break down, and its elasticity is significantly reduced.

[0089] Due to these changes, the surface elasticity coefficient of the tobacco in the burning section will decrease significantly, even approaching zero (i.e., it loses elasticity; therefore, the tobacco in the burning section usually no longer has obvious elastic properties).

[0090] Estimation of elasticity coefficient:

[0091] Unburned tobacco: Unburned tobacco may have a certain degree of elasticity, with an elasticity coefficient of approximately 1 N / m to 10 N / m (the specific value depends on the density, moisture content and structure of the tobacco).

[0092] Burning tobacco: The elasticity of the tobacco in the burning part will decrease rapidly, possibly approaching 0 N / m, because combustion will cause its structure to break down and lose its elasticity.

[0093] Therefore, the surface elasticity coefficient of the tobacco shreds in the combustion section is usually close to 0 N / m, because the combustion process destroys its structure and causes it to lose its elasticity. If a more accurate value is needed, the changes in the mechanical properties of the tobacco shreds during combustion must be measured experimentally. Different types of tobacco shreds, combustion time, and loading methods will all affect the results.

[0094] In the experiment of this application, empirical conclusions were used as parameters, namely the pressure of pressing the marshmallow with a finger, which caused the marshmallow to change shape slightly.

[0095] The elastic modulus (k) of marshmallows is usually low because it is a soft and easily compressible material. According to experimental data, the elastic modulus of marshmallows is approximately between 10 N / m and 100 N / m. For calculation purposes, we can take an intermediate value, such as k = 50 N / m.

[0096] The calculation steps are as follows:

[0097] Elasticity coefficient k:

[0098] Assume k = 50 N / m;

[0099] Compression distance x:

[0100] The compression distance is 1 millimeter, which is converted to meters: x = 1 mm = 0.001 m;

[0101] Calculate the force F:

[0102] According to Hooke's Law: F=k*x=50N / m*0. Tobacco press head (1) m=0.05N;

[0103] Therefore, using the average elastic coefficient of marshmallow k=50N / m, the force required to compress 1 mm is 0.05 Newtons (approximately 5 gf, since 1N≈100gf).

[0104] Therefore, the known conditions in this application are as follows:

[0105] Estimated distance: r = 12mm = 0.012m;

[0106] Force applied: F = 5gf = 0.049N;

[0107] Magnet dimensions: 6mm in diameter, 5mm in height, volume V is:

[0108] V=πr 2 h=π*(3*10 -3 ) 2 *(5x10 -3 )≈1.41*10 -7 m 3 ;

[0109] Vacuum permeability: μ0 = 4π * 10 -7 N / A 2 ;

[0110] Therefore, it can be concluded that the two magnets are balanced by a force of 0.05N when they are 12mm apart.

[0111] Target:

[0112] Based on the visually estimated distance r=0.012m and the applied force F=0.049N, the magnetic pole strength m is inferred, and the calculation is verified to be reasonable.

[0113] Force formula for the magnetic dipole model:

[0114] For two identical cylindrical magnets, the formula for the repulsive force between like poles is:

[0115] Recalculate:

[0116] Contact magnetic pole strength m:

[0117]

[0118] Substitute the known values:

[0119] Simplified calculation:

[0120]

[0121] ≈0.0713

[0122] Therefore, the conclusion is:

[0123] Using the magnetic dipole model, the calculated magnetic pole strength is closer to the theoretical value, indicating that the repulsive force between the two magnets at a distance of 12 millimeters is about 5 grams.

[0124] That is, under the action of 5 g force (0.049 N), the balance distance between the two cylindrical magnets (6 mm in diameter and 5 mm in height) is about 12 mm. This result is consistent with visual observation and its rationality is verified by the magnetic dipole model.

[0125] Therefore, it can be seen that when the user presses down on the tobacco, the distance between the two magnets is less than 12mm, which reduces the force and achieves a perfect combustion layer.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
