[0027] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0028] In the description of the present invention, it should be noted that, unless otherwise specified, "multiple" means two or more than two; the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1 As shown, the smoke ring cannon comprises a base 1, a mounting box 2 is fixedly connected to the base 1, a barrel body 3 is rotatably connected to the top of the mounting box 2, a firing membrane 5 is installed near the right side of the barrel body 3, a smoke generator 7 for generating smoke is arranged at the left side of the firing membrane 5 in the barrel body 3, a surface A is arranged in the barrel body 3, the surface A is the cross section of the inner wall of the barrel body 3, the surface A passes through the spray end of the smoke generator 7, and the area of ​​the surface A is S A The muzzle of the barrel body 3 is located at the left end of the barrel body 3, and the cross section of the inner wall of the muzzle of the barrel body 3 is surface B, and the area of ​​surface B is S B ;

[0031] 0.2≤S B / S A ≤0.7.

[0032] In the present embodiment, the firing membrane 5 is driven by a one-way reciprocating drive mechanism 6 which is arranged in the barrel body 3 and is located on the right side of the firing membrane 5 ; the one-way reciprocating drive mechanism 6 can pull the firing membrane 5 back and forth.

[0033] The smoke generated by the smoke generator 7 is generated by the smoke oil being electrically heated in the hollow heating tube in the smoke generator 7 .

[0034] The principle of the present invention is:

[0035] After the smoke oil pumped into the hollow heating tube is heated by the smoke generator 7 to generate smoke, the one-way reciprocating drive mechanism 6 pulls the firing membrane 5 to blow the smoke out of the barrel body 3. Based on the principles of aerodynamics and fluid mechanics, in theory, first of all, it is necessary to ensure that S B <S A The air ejected from the "small hole" (the muzzle of the barrel body 3) has a high pressure. When this high-pressure air flows outward, it will drive the surrounding static air to flow together. This flow from high pressure to low pressure forms a vortex. When smoke particles are confined in this vortex, they form a circle and move forward, thus forming a "smoke ring" visible to the naked eye.

[0036] Therefore, the barrel body 3 is a tapered barrel, which makes it easier to achieve S B <S A .

[0037] This type of toy that uses a cannon-like structure to simulate the emission of smoke rings is more interesting and is particularly suitable for places such as playgrounds, as it is safer.

[0038] In the experiment, it was found that based on the cone structure (the inner wall cone angle is 11°) and the aerodynamic force generated by the use of the firing membrane 5, a large number of experiments were conducted and it was found that S B / S A The value will seriously affect the clarity of the emitted smoke rings.

[0039] Group 1: For example, S B / S A = 0.1, the emitted smoke is just a ball and cannot form a clear smoke ring. Figure 2 shown.

[0040] Group 2: For example, S B / S A = 0.8, the smoke emitted is also relatively scattered, and the smoke ring is barely formed but very irregular and not condensed. Figure 3 shown.

[0041] Group 3: For example, S B / S A= 0.9, the emitted smoke is very scattered and the smoke ring is almost not formed. Figure 4 As shown; the smoke ring is obviously Figure 3 More scattered.

[0042] After a lot of experiments, it is preferred that 0.2≤S B / S A ≤0.7.

[0043] Group 4: Going a step further, when S B / S A = 0.4, that is, the diameter of the smoke outlet (the position of the B surface) is 220mm, and the diameter of the cross section where the smoke generator 7 is located (the A surface) is 350mm; the smoke ring emitted by it is as follows Figure 5 As shown, it is very clear and cohesive.

[0044] Example 2

[0045] Because the main audience of the smoke ring cannon is children, protective measures are taken to prevent children from putting their hands into the barrel body 3 and contacting the smoke generator 7, which may bring safety risks. A protective net 10 is provided in the barrel body 3 and is located between the B surface and the A surface.

[0046] The mesh of the protection net 10 is circular, hexagonal, rhombus or square.

[0047] In the test, it was found that the shape of the mesh of the protective net 10 does not affect the smoke ring forming effect, but the size of the mesh of the protective net 10 will obviously affect the smoke ring forming effect. If the mesh of the protective net 10 is too large, the protection effect will be poor. If the mesh of the protective net 10 is too small, the smoke ring will not be able to shoot farther.

[0048] For example, the smoke ring in group 4 can still maintain sufficient condensation when it is about 4m away from the muzzle of the barrel body 3. Figure 5 In group 4, the mesh of the protective net 10 is a regular hexagon, and the side length of the regular hexagon is 2 cm.

[0049] Group 5: The difference from Group 4 is that the mesh of the protective net 10 of this group is a regular hexagon with a side length of 1 cm. The smoke rings emitted by it start to become scattered when it is about 3m away from the muzzle of the barrel body 3. When it is subsequently emitted about 1-2m away from the muzzle of the barrel body 3, it is very clear and condensed. Figure 6 .

[0050] Example 3

[0051] The e-liquid is an alcohol substance, and the alcohol substance includes one or more of n-propanol, isopropanol, propylene glycol, and glycerol. For example, the e-liquid is a mixture of propylene glycol and glycerol in any ratio.

[0052] The experiment found that the effect of smoke rings is related to the physical properties of smoke particles. The smoke produced by alcohol substances is easily carried away by airflow; that is, once there is a breeze near the smoke ring cannon, it will cause the smoke ring to be easily blown away.

[0053] The inventor discovered in his experiment that n-propyl acetate, which was originally used to be added to the e-liquid as a fragrance substance, is a permitted edible flavoring in GB 2760-96, thereby increasing the customer experience. However, it was unexpectedly discovered that after adding n-propyl acetate to the e-liquid, it was found that it had a good wind resistance effect.

[0054] Group 6: According to the parameter settings of Group 4, the smoke oil includes alcohol substances and n-butyl acetate, and the mass fraction of n-butyl acetate in the smoke oil is 1.3%; it is subjected to the "Smoke Ring Anti-Breeze Test", and the photos of the smoke rings are shown in Figure 7 , the smoke ring is still very condensed and clear at about 3m.

[0055] Smoke ring resistance to breeze test

[0056] The industrial electric fan is 3m away from the smoke ring cannon and uses the lowest gear with an outlet wind speed of 1m / s to create a breeze environment on site. In this breeze environment, check the clarity of the smoke ring.

[0057] Group 7: This group differs from Group 6 in that amyl acetate was used instead of n-butyl acetate. In the "Smoke Ring Resistance to Breeze Test", the smoke ring photos are shown in Figure 8 At the arrow point, the smoke ring is about 2m away and is not clear.

[0058] Group 8: This group differs from Group 6 in that propyl acetate was used instead of n-butyl acetate. In the “Smoke Ring Resistance to Breeze Test”, the smoke rings were photographed at Fig. 9 The smoke ring is about 3m away, and the smoke ring is not as clear and condensed as Figure 7 .

[0059] Example 4

[0060] To increase the fun, a music atmosphere light 9 is installed near the B surface in the barrel body 3.

[0061] When the smoke ring is emitted, the music atmosphere lamp 9 can flash and emit music, further enhancing the fun.

[0062] In addition, a QR code may be provided on the outer side wall of the barrel body 3. The user can start the smoke ring cannon after paying by scanning the QR code.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
