Timing smoke control device

Abstract

The utility model discloses a timing smoke control device which comprises a body, a mechanical timer, an outer cover assembly and an annular inner cover. A first via hole is formed in the annular inner cover, and a second via hole is formed in the outer cover assembly; a cigarette can pass through the first via hole and the second via hole; the outer cover assembly rotates the output shaft so that the second via hole can rotate from the first cigarette groove to the second cigarette groove, and the first via hole is driven to rotate to the cigarette groove adjacent to the first via hole. Due to the fact that the first through hole rotates in one direction, when the mechanical timer releases the elastic energy, the mechanical timer also needs a certain time to release the elastic energy, within the time, the first through hole cannot rotate to the next cigarette groove again, the second through hole and the first through hole can be continuously rotated only after a period of time, and the next cigarette can be taken out. The purpose of assisting smoking cessation is achieved by limiting the interval time of taking out the cigarettes. The smoke control device adopts a mechanical structure, does not need an electronic structure, is simple in structure and lower in cost, and is more beneficial to application and popularization.

Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of smoke control appliance, especially is a kind of timing smoke control device. BACKGROUND

[0002] Tobacco epidemic and harm is one of the biggest public health problems threatening human health, and tobacco use is the risk factor for six of the world's eight leading causes of death. Many studies have confirmed that tobacco is a high-risk factor for many chronic diseases, for example, nicotine in tobacco is a highly addictive substance that can cause chronic addictive diseases and other chronic diseases. Studies have shown that more than half of smokers have the intention to quit smoking, but still have many smokers who fail to quit smoking. Nicotine and other physiological dependence are the primary reason for smoking cessation failure. Reducing the amount of smoke or stopping smoking will quickly reduce the nicotine concentration in the body. The commonly used smoking cessation methods are one-time withdrawal method and gradual reduction method, and the difficulty of smoking cessation is that it is not easy to persist. Therefore, a smoking cessation appliance can be used to assist smoking cessation.

[0003] In the prior art, most smoking cessation appliances have electronic structures, for example, the patent document with publication number CN211794302U discloses a smoke control device configured with a display screen, a power storage group and a timer.

DETAILED DESCRIPTION

[0078] To make the objectives, technical solutions and advantages of the present application clearer and more explicit, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0079] Please also refer to Figures 1-22 The present application provides some preferred embodiments of a timing-based cigarette control device.

[0080] As Figure 1 , Figure 2 and Figure 14 indicate, the timing-based cigarette control device comprises:

[0081] a body 10, provided with at least three cigarette slots for accommodating cigarettes, the at least three cigarette slots comprising a first cigarette slot 101 and a second cigarette slot 102;

[0082] a mechanical timer 20 arranged in the body 10;

[0083] an outer cover assembly 30 rotatably arranged in the body 10 and connected with an output shaft 22 of the mechanical timer 20;

[0084] an annular inner cover 40 rotatably arranged between the outer cover assembly 30 and the body 10;

[0085] The first via hole 41 and the second via hole 311 can rotate to the corresponding positions of the cigarette grooves, and the cigarette can pass through the first via hole 41 and the second via hole 311. The outer cover assembly 30 rotates the output shaft to make the second via hole rotate from the first cigarette groove 101 to the second cigarette groove 102, and drive the first via hole 41 to rotate to the adjacent cigarette groove of the first via hole.

[0086] Specifically, the cigarette groove refers to a groove body for accommodating a cigarette. The number of cigarette grooves can be set to at least 3 according to needs, for example, the number of cigarette grooves is 10, and one cigarette can be placed in each cigarette groove. The cigarette groove has a slot, and the cigarette can be taken out from the slot of the cigarette groove. The mechanical timer 20 refers to a timing element driven by a mechanical structure, which can be used to indicate the measured cumulative period or time. The mechanical timer 20 does not carry electronic structures such as batteries, circuits or electric drivers. The mechanical timer 20 has an output shaft 22, which sets the time period required for timing. The mechanical timer 20 can be an elastic mechanical timer. The elastic structure in the elastic mechanical timer can store and release elastic energy. The elastic structure can be a torsional spring, a clockwork, etc., forming a torsional spring type mechanical timer, a clockwork type mechanical timer, etc. Specifically, the clockwork type mechanical timer uses a clockwork as a driving structure for timing, and the output shaft 22 is connected to the clockwork. Figure 14 As shown in FIG. 2, when the output shaft 22 rotates from the initial position to the first direction, the clockwork is deformed. In the process of restoring the deformation, the clockwork drives the output shaft 22 to rotate slowly in the second direction and returns to the initial position. The first direction and the second direction are opposite directions, for example, the first direction is counterclockwise and the second direction is clockwise. After the output shaft 22 rotates from the initial position to the first direction by a preset angle α, the output shaft 22 rotates in the second direction and returns to the initial position, which takes a certain time, thereby realizing timing. In one timing cycle, the output shaft 22 rotates from the initial position in the first direction to store elastic energy. When the elastic energy is released, the output shaft 22 rotates in the second direction and returns to the initial position. The maximum angle of the output shaft 22 rotating from the initial position in the first direction of the mechanical timer 20 is usually within 360°.

[0087] The outer cover assembly 30 is rotatably connected to the body 10, for example, the edge of the outer cover assembly 30 is clamped to the top of the body 10, and the outer cover assembly 30 can rotate relative to the body 10. The cavity is formed between the outer cover assembly 30 and the body 10, and the annular inner cover 40 is located in the cavity and can rotate in the cavity. The outer cover assembly 30 is connected with the output shaft 22 of the mechanical timer 20, and the outer cover assembly 30 can drive the annular inner cover 40 and the output shaft 22 to rotate when the outer cover assembly 30 rotates. With the rotation of the output shaft 22, the annular inner cover 40 also rotates, and the annular inner cover 40 adopts a one-way step-by-step rotation form. In a timing period, the outer cover assembly 30 rotates by a preset angle α (i.e. the angle from the first cigarette slot 101 to the second cigarette slot 102), and the annular inner cover 40 rotates once in one direction, and the angle β of each rotation is the same, which is the included angle between adjacent cigarette slots. Specifically, there are two cases:

[0088] The first case, the outer cover assembly 30 rotates once to take out the cigarette. In a timing period, the outer cover assembly is rotated in the first direction, the second through hole 311 is rotated from the first cigarette slot 101 to the position of the second cigarette slot 102 (as shown in Figure 13 and Figure 16 ), and the first through hole 41 can be rotated to the position of the adjacent cigarette slot (as shown in Figure 14 and Figure 17 ), and the adjacent cigarette slot of the first through hole 41 is the second cigarette slot 102. Therefore, the second cigarette slot 102, the first through hole 41 and the second through hole 311 correspond to each other, and the cigarette in the second cigarette slot 102 can be taken out.

[0089] The second case, the outer cover assembly 30 needs to be rotated twice to take out the cigarette. In a timing period, the outer cover assembly is rotated in the first direction for the first time, the second through hole 311 is rotated from the first cigarette slot 101 to the position of the second cigarette slot 102 (as shown in Figure 13 and Figure 16 ), and the first through hole 41 can be rotated to the position of the adjacent cigarette slot (as shown in Figure 19 and Figure 20 ), and the adjacent cigarette slot of the first through hole 41 can not be the second cigarette slot 102 (for example, it can be the third cigarette slot 103). Therefore, the outer cover assembly needs to be rotated in the second direction for the second time (as shown in Figure 21 and Figure 22 ), and the outer cover assembly rotates the second through hole 311 to the adjacent cigarette slot of the first through hole 41, so as to take out the cigarette in the adjacent cigarette slot of the first through hole 41.

[0090] When the outer cover assembly 30 rotates from the initial position and drives the output shaft 22 to rotate (of course, the second through hole 311 also rotates), the mechanical timer 20 accumulates elastic energy, and after the outer cover assembly 30 is loosened, the mechanical timer 20 releases the elastic energy and drives the outer cover assembly 30 to rotate back to the initial position (the second through hole 311 also rotates back to the initial position). Because the outer cover assembly 30 carries the second through hole 311 to rotate a preset angle α, the first through hole 41 can only rotate to the position of one cigarette slot in one direction, and in the time when the mechanical timer 20 releases the elastic energy, the first through hole 41 cannot rotate to the next cigarette slot again, and can only continue to rotate the second through hole 311 and the first through hole 41 after a period of time, so that the next cigarette can be taken out, therefore, the timing control device of the application can limit the interval time of taking out the cigarette, and achieve the purpose of assisting in smoking cessation.

[0091] The timing control device of the application adopts a mechanical structure, does not need an electronic structure, has simple structure, and has lower manufacturing cost, and is more beneficial to application and promotion.

[0092] When the outer cover assembly 30 rotates from the initial position and drives the first through hole 41 and the second through hole 311 to rotate, the second through hole 311 can rotate from the initial corresponding first cigarette slot 101 to the corresponding position of the second cigarette slot 102, and the first cigarette slot 101 and the second cigarette slot 102 can be adjacent cigarette slots, or can not be adjacent cigarette slots (there is at least one cigarette slot between the first cigarette slot 101 and the second cigarette slot 102), and then the preset angle α of the second through hole 311 rotating can be greater than or equal to the angle β of the first through hole 41 rotating. When the second through hole 311 rotates to the second cigarette slot 102, the first through hole 41 can rotate to the corresponding position of the adjacent cigarette slot of the first through hole 41 in one direction, and the first through hole 41 can traverse all the cigarette slots through multiple rotations. Of course, when the number of the cigarette slots is odd, the first through hole 41 can rotate to the corresponding position of the interlaced cigarette slot in one direction, or can traverse all the cigarette slots, and there is also one adjacent cigarette slot between the interlaced cigarette slot and the initial corresponding cigarette slot.

[0093] The annular inner cover 40 is provided with the first through hole 41, and the outer cover assembly 30 is provided with the second through hole 311, and the first through hole 41 and the second through hole 311 can rotate to the positions corresponding to the cigarette slots (specifically, the positions corresponding to the slot openings of certain cigarette slots), so that the cigarettes in the cigarette slots can be taken out through the slot openings and the first through hole 41 and the second through hole 311. It can be seen that when the positions of the first through hole 41, the second through hole 311 and certain cigarette slots correspond to each other, the cigarettes in the cigarette slots can be taken out.

[0094] In a preferred embodiment of the utility model, please refer to Figure 2 、 Figures 10-12 ​The body 10 is provided with a first-level groove 111, the bottom of the first-level groove 111 is provided with a second-level groove 112 and the cigarette groove, and the second-level groove 112 is connected with an expansion groove 113.

[0095] Specifically, the body 10 is provided with a multi-level groove, which comprises the first-level groove 111 and the second-level groove 112, the size of the first-level groove 111 is larger, and the size of the second-level groove 112 is smaller. The second-level groove 112 is located at the center position of the body 10, the cigarette groove is arranged on the first-level groove 111, and a plurality of cigarette grooves are arranged around the second-level groove 112. The second-level groove 112 is circular, and since the second-level groove 112 is connected with the expansion groove 113, the two as a whole present a non-circular shape.

[0096] In a preferred embodiment of the utility model, please refer to Figures 1-2 、 Figures 7-12 The annular inner cover 40 is located in the first-level groove 111, and the annular inner cover 40 is provided with a plurality of inner teeth 42; the outer cover assembly 30 comprises:

[0097] The twist cover 31 is rotationally connected with the body 10, and the second through hole 311 is arranged on the twist cover 31;

[0098] The rotating part 32 is located in the second-level groove 112 and is connected with the output shaft 22;

[0099] Wherein, the twist cover 31 is provided with a protruding block 312; the rotating part 32 is formed with an elastic arm 321 and an extension arm 322; the end portion 3211 of the elastic arm 321 is located in the expansion groove 113 and abuts against the abutting surface 421 of the inner tooth 42, and the side, away from the abutting surface 421, of the inner tooth 42 is formed with a guide surface 422; the extension arm 322 abuts against the protruding block 312.

[0100] Specifically, as Figure 5 、 Figure 9 And Figure 12As shown, the rotating member 32 is located in the secondary groove 112 and can rotate in the secondary groove 112. The outer cover assembly 30 is provided with a protrusion 312, and the rotating member 32 is provided with an extension arm 322, the base of the extension arm 322 is connected with the rotating member 32, and the extension arm 322 abuts against the protrusion 312. When the outer cover assembly 30 is rotated in the first direction, the protrusion 312 pushes the extension arm 322, so that the outer cover assembly 30, the rotating member 32 and the output shaft 22 are synchronously rotated in the first direction (the annular inner cover 40 is also driven to rotate unidirectionally by an angle β, and the preset angle α of the outer cover assembly 30 rotated in the first direction is greater than or equal to the angle β), and the elastic structure is stored. After the outer cover assembly 30 is released, the elastic structure drives the output shaft 22 to rotate in the second direction, and pushes the outer cover assembly 30 to rotate, and since the extension arm 322 abuts against the protrusion 312, the outer cover assembly 30 is also driven to rotate in the second direction, and the annular inner cover 40 does not rotate.

[0101] When the outer cover assembly 30 is rotated in the first direction, the protrusion 312 pushes the extension arm 322 to rotate, and at this time, the extension arm 322 is not deformed. The extension arm 322 is located in the expansion groove 113 and pushes the abutting surface 421 of the inner tooth 42 in the expansion groove 113 to rotate in the first direction, so as to drive the rotating member 32 to rotate in the first direction. When the rotating angle reaches the preset angle α, the end portion 3211 of the elastic arm 321 slides out of the expansion groove 113 and is completely located in the secondary groove 112, at this time, the end portion 3211 of the elastic arm 321 is separated from the inner tooth 42 and cannot drive the inner tooth 42 to continue to push the inner tooth 42 in the first direction. Even if the end portion 3211 of the elastic arm 321 continues to rotate in the first direction, as long as the rotating angle is less than 360° (for example, the maximum angle of the output shaft 22 of the mechanical timer 20 rotated in the first direction from the initial position can be configured to be within 360°), the rotating member 32 will not be pushed to rotate again.

[0102] When the mechanical timer 20 releases the elastic energy, the output shaft 22 drives the rotating member 32 to rotate in the second direction, and drives the protrusion 312 and the outer cover assembly 30 to rotate in the second direction through the extension arm 322. The end portion 3211 of the elastic arm 321 is completely located in the secondary groove 112 and does not contact the inner tooth 42, and cannot push the rotating member 32 to rotate. Even if the end portion 3211 of the elastic arm 321 returns to the expansion groove 113 in the second direction, the end portion 3211 of the elastic arm 321 contacts the guide surface 422 of the inner tooth 42, and under the guidance of the guide surface 422, the elastic arm 321 is deformed by extrusion, and the elastic arm 321 cannot push the inner tooth 42 to move in the second direction. In summary, in a timing period, the rotating member 32 rotates only once (or one step, that is, step-by-step rotation), and the rotating member 32 forms unidirectional rotation.

[0103] The number of the inner teeth 42 can be the same as the number of the accommodating grooves, and the first through hole 41 rotates to the position of the adjacent cigarette groove every time the inner teeth 42 (or the rotating piece 32) rotates once. The number of the inner teeth 42 can also be half of the number of the accommodating grooves, and the first through hole 41 rotates to the position of the intermitted cigarette groove every time the inner teeth 42 (or the rotating piece 32) rotates once.

[0104] The lower surface of the elastic arm 321 is located in the secondary groove 112, and the outer side of the elastic arm 321 abuts against the groove wall of the secondary groove 112, so as to limit the bending range of the elastic arm 321. The rotating piece 32 is formed with a space for avoiding position, which is used for the inward bending deformation of the elastic arm 321. The elastic arm 321 extends in the first direction.

[0105] In a preferred embodiment of the utility model, please refer to Figure 2 、 Figure 5 and Figure 7 , the edge of the twist cover 31 is provided with a plurality of rough parts 314.

[0106] Specifically, in order to increase the friction between the twist cover 31 and the hand of the user, a plurality of rough parts 314 are arranged on the edge of the twist cover 31, and the rough parts 314 are arranged around the edge of the twist cover 31. When the user rotates the twist cover 31, the fingers contact the rough parts 314 and rotate the twist cover 31 in the first direction.

[0107] In a preferred embodiment of the utility model, please refer to Figures 7-9 、 Figure 15 、 Figure 18 and Figure 22 , the twist cover 31 is provided with a first limiting part 315; the edge of the primary groove 111 is provided with a second limiting part 1111, the second limiting part 1111 limits the first limiting part 315; wherein when the second through hole rotates to the second cigarette groove 102, the second limiting part abuts against the first limiting part.

[0108] Specifically, in order to further limit the rotating range of the rotating piece 32 within 360°, the first limiting part 315 is arranged on the inner side of the twist cover 31, and the second limiting part 1111 is arranged on the edge of the primary groove 111, when the twist cover is rotated to move the first limiting part to the position of the second limiting part, the first limiting part is blocked by the second limiting part, and the twist cover cannot continue to rotate. Due to the limitation of the first limiting part 315 and the second limiting part 1111, the twist cover 31 cannot rotate more than 360°, so the rotating piece 32 and the output shaft 22 cannot rotate more than 360° in the first direction, and the elastic arm 321 cannot push the inner teeth 42 to rotate twice, so as to ensure that the rotating piece 32 rotates only once in a timing cycle. In the initial state, the first through hole 41 and the second through hole 311 are usually corresponding to a cigarette groove (for example Figure 3And Figure 15 As shown in FIG. 1, the first limiting portion 315 and the second limiting portion 1111 are separated from each other. As shown in FIG. 2, the first limiting portion 315 and the second limiting portion 1111 are abutted against each other. Figure 14 As shown in FIG. 1, the first through hole is located at the position of the first cigarette slot 101, and the second through hole is located at the position of the third cigarette slot 103 in the at least three cigarette slots. The cigarette in the first cigarette slot 101 is blocked by the cap 31 and cannot be taken out. As shown in FIG. 2, the cap 31 is rotated in the first direction, and the second through hole 311 is located at the position corresponding to the first cigarette slot 101, so that the cigarette in the first cigarette slot 101 can be taken out. Figures 13-15 As shown in FIG. 1, the first through hole is located at the position of the first cigarette slot 101, and the second through hole is located at the position of the third cigarette slot 103 in the at least three cigarette slots. The cigarette in the first cigarette slot 101 is blocked by the cap 31 and cannot be taken out. As shown in FIG. 2, the cap 31 is rotated in the first direction, and the second through hole 311 is located at the position corresponding to the first cigarette slot 101, so that the cigarette in the first cigarette slot 101 can be taken out.

[0109] Specifically, in the first direction, when the second through hole is rotated to the position of the second cigarette slot 102, the first limiting portion and the second limiting portion abut against each other, so that the second through hole cannot continue to rotate in the first direction. At this time, the first through hole has been rotated to the adjacent cigarette slot. If the adjacent cigarette slot of the first through hole is the second cigarette slot 102, the first through hole and the second through hole are located at the positions corresponding to the second cigarette slot 102, and the cigarette in the second cigarette slot 102 can be taken out. If the adjacent cigarette slot of the first through hole is not the second cigarette slot 102 (for example, it can be the third cigarette slot 103), the cap needs to be rotated in the second direction to rotate the second through hole to the position corresponding to the first through hole, so that the cigarette in the adjacent cigarette slot of the first through hole can be taken out.

[0110] In a preferred embodiment of the present application, the sum of the central angles corresponding to the first limiting portion and the second limiting portion is 1 / 2~1 of the included angle between the two adjacent cigarette slots.

[0111] Specifically, in the first direction, the first limiting portion can rotate and abut against the second limiting portion, and the protruding block can rotate and abut against the end of the extension arm. In order not to affect the timing of the mechanical timer, in the second direction, when the first limiting portion rotates and abuts against the second limiting portion, the protruding block cannot abut against the end of the extension arm, so that the extension arm cannot be driven to rotate in the second direction, and can only be driven to rotate in the second direction by the mechanical timer. When the sum of the central angles corresponding to the first limiting portion and the second limiting portion is 1 / 2~1 of the preset angle α (the preset angle α is equal to the included angle between the two adjacent cigarette slots), the protruding block cannot drive the extension arm to rotate in the second direction. In the second direction, when the first limiting portion rotates and abuts against the second limiting portion, the second through hole can be rotated to the adjacent cigarette slot of the second cigarette slot 102 (the cigarette slot is located on the two sides of the second cigarette slot 102, respectively.

[0112] In a preferred embodiment of the utility model, the expansion groove comprises: lower concave wall 1131, convex wall 1132 and arc wall 1133 connected in sequence, wherein when the second through hole rotates from the first cigarette groove 101 to the second cigarette groove 102, the end of the elastic arm sequentially passes through the lower concave wall 1131, the convex wall 1132 and the arc wall 1133.

In the initial position, the end of the elastic arm is located at the corresponding position of the lower concave wall 1131, when the elastic arm is rotated in the first direction, the end of the elastic arm slides from the lower concave wall 1131 to the convex wall 1132 and pushes the abutting surface of the inner tooth, and the annular inner cover is rotated in the first direction. Until the end of the elastic arm passes through the convex wall 1132 and the arc wall 1133 to reach the second end of the groove wall of the secondary groove, the end of the elastic arm is completely located in the secondary groove and cannot push the abutting surface of the inner tooth, the annular inner cover stops rotating, and the first through hole rotates to the position of the adjacent cigarette groove. When the cap is loosened, the end of the elastic arm is rotated in the second direction and sequentially passes through the arc wall 1133 and the convex wall 1132, at this time, the convex wall 1132 is located at the corresponding position of the guide surface of the inner tooth, and under the guidance of the convex wall 1132, the end of the elastic arm slides along the guide surface and is not easy to push the annular inner cover to rotate in the second direction. After the end of the elastic arm passes the inner tooth, it moves to the lower concave wall 1131 and restores the deformation.
