Description

Technical Field

[0001] This disclosure relates to the field of tobacco accessory equipment, and more specifically, to a portable cigarette injector for dispensing a lung-cleansing agent. Background Technology

[0002] In today's society, due to excessive pressure, smoking has become a daily pastime for most people. However, smoking is harmful. Tobacco contains toxic nicotine, which can easily cause coughs such as laryngitis, bronchitis, and emphysema. Nicotine is slowly excreted through the body's metabolism after people stop smoking, but this process takes a long time. For long-term smokers, the metabolic efficiency is low and the effect is slow. Injecting lung-cleansing agents into cigarette filters can help regulate the body's cardiopulmonary function and reduce the harm of smoking to the body. This will become the best way for modern people to balance enjoyment and health. Based on this, there is a large potential market demand for cigarette injectors.

[0003] Existing sprayers have simple structures. For example, patent CN201521021311.2 describes a portable auxiliary smoking cessation device that releases an adsorbent for harmful substances in cigarettes. This device is only suitable for spraying one type of cigarette. Furthermore, due to the lack of a cigarette clamping mechanism, cigarettes that are not properly inserted will be pushed out by the spraying force during liquid spraying, resulting in ineffective spraying. In addition, existing sprayers only provide single-liquid spraying. Considering the diversity of spraying needs while maintaining a compact and portable design, a sprayer that can support two or more liquids can meet the diverse needs of smokers, making its promotion prospects more effective.

[0004] In view of this, this utility model designs a convenient cigarette sprayer for releasing lung-cleansing agents, and adds a highly operable and compact clamping mechanism to solve the problem of universal clamping of cigarettes of different sizes.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0028] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0029] According to one aspect of this disclosure, a portable cigarette sprayer for dispensing a lung-cleansing agent is provided, comprising a housing 4, a cap 1, a liquid bottle 7, a spray needle 9, a spraying mechanism 5, and a clamping mechanism; as shown... Figures 1-4 As shown, where,

[0030] The spraying mechanism 5 adopts a conventional structure, including a pressing head 2, a piston, a liquid storage tank 51, a one-way valve, and a suction tube 52. The liquid bottle 7 is detachably threaded and sealed to the liquid storage tank 51, and is connected to the liquid storage tank 51 through the suction tube 52 that extends into the bottle. A one-way valve is provided at the liquid inlet at the middle of the lower end of the suction tube 52 and the liquid storage tank 51. The one-way valve cuts off the liquid path from the liquid bottle 7 to the liquid storage tank 51 in one direction. The piston is connected to the pressing head through the valve stem to provide negative pressure suction force and positive pressure spraying force. A liquid outlet is provided at the lower end of the liquid storage tank 51. The spraying needle tube 9 is connected to the liquid outlet through a rubber tube. Similarly, a one-way valve is provided outside the liquid outlet to cut off the liquid path from the liquid storage tank 51 to the spraying needle tube 9 in one direction.

[0031] The upper end face of the housing 4 is provided with a cigarette socket 41 and a pressing head 2. The injection needle 9 is located in the middle of the cigarette socket 41. The injection needle 9 has evenly distributed micro-holes on its end face and the peripheral surface of its end section. The depth of the injection needle 9 and the length of the micro-hole section are designed according to the insertion depth of the smallest and largest cigarette sizes to ensure that the injection area is located in the filter section of the cigarette. The upper end face of the housing 4 is provided with a cover 1 for sealing to ensure hygiene. The inner cavity of the housing 4 is divided into a cigarette placement area on one side and a liquid placement area on the other side. The liquid bottle 7 is placed in the liquid placement area. A transparent observation window is provided on the liquid placement area to facilitate timely understanding of the remaining liquid. An adjustment window 42 is opened on the side of the housing 4, which extends to the cigarette placement area. The width of the adjustment window 42 is designed so that it can be touched and operated by the thumb. The cigarette socket 41 is located at the upper end of the cigarette placement area and is connected to the cigarette placement area.

[0032] The bottom of the housing 4 is detachably fitted with a snap-fit ​​base plate 8. The snap-fit ​​base plate 8 is provided with a stepped groove for flexibly supporting the liquid bottle 7. After the liquid bottle 7 is installed, the snap-fit ​​base plate 8 snaps in to provide flexible support.

[0033] A clamping mechanism is located within the cigarette placement area to clamp cigarettes inserted through the cigarette holder 41. To provide clamping force, it can accommodate various cigarette sizes, such as... Figure 3 and Figure 4 As shown, the clamping mechanism includes an adjusting sleeve 3 and an elastic clamping body 10;

[0034] The adjusting sleeve 3 is located in the smoke-collecting area. It consists of an integral adjusting threaded head 32, a variable clamping hole, a guide end plate 4333, and an adjusting knob 31. The end plate 43 of the adjusting window 42 has a threaded adjusting hole, and the smoke-collecting area has a telescopic space located outside both ends of the adjusting window 42. Therefore, the adjusting threaded head 32 is threadedly connected to the end plates 43 at both ends, and when the adjusting knob 31 is rotated, the adjusting sleeve 3 moves up and down, changing the sizing position of the adjusting cone hole 34 in the adjusting knob 31. The adjusting cone hole 34 is cone-shaped.

[0035] The elastic clamping body 10 is a clamping structure with a variable cone hole diameter at the clamping position, as referred to again. Figure 4 The elastic clamping body 10 is conical in shape, with a variable clamping hole in the shape of a cone inside. The adjustable cone hole 34 is fitted onto the conical circumferential surface of the elastic clamping body 10 and applies a radial contraction clamping force. The cigarette is inserted through the cigarette insertion hole 41 and extends into the variable clamping hole. By adjusting the position of the adjustable cone hole 34, the elastic sheet 102 of the elastic clamping body 10 gradually contracts radially, elastically pressing the cigarette filter.

[0036] In one exemplary embodiment of this disclosure, in order to reliably install and fix the clamping body, a base post 11 is provided at the bottom of the cigarette placement area, and a stepped circle is provided inside the cigarette insertion hole 41, referring again to Figure 4The elastic clamping body 10 includes an integrally stamped positioning flange 101, several elastic sheets 102, and a positioning sleeve 103. The elastic sheets 102 provide radial elastic deformation. The several elastic sheets 102 are arranged in a uniform annular array to form a variable clamping hole. The elastic sheets 102 have gaps in the middle to provide variable diameter shrinkage. One end of the elastic sheet 102 is connected to the annular plate-shaped positioning flange 101, and the other end is connected to the cylindrical positioning sleeve 103. The positioning flange 101 is clamped on the stepped circle and a pressure ring is provided for further compression. The positioning sleeve 103 is sleeved on the base column 11 and is connected to the base column 11 by a nut for clamping. The elastic sheets 102 all pass through the adjusting cone hole 34 and fit against the circumferential surface of its inner cone hole. In addition, in order to maintain the radial shrinkage clamping force at different clamping positions and provide the required elastic deformation of the elastic sheet 102, the two ends of the elastic sheet 102 are integrally formed with a corrugated structure 104.

[0037] The injection needle tube 9 is installed in the middle of the upper end face of the base column 11. A tube hole is provided in the middle of the base column 11, and the hose passes through the tube hole to connect to the injection needle tube 9.

[0038] In an exemplary embodiment of this disclosure, the adjustment window 42 is formed by the end plates 43 at both ends, the inner arc plate, and the window located on the side of the housing 4. It has the advantages of aesthetics, structural strength, and easy cleaning. The end plates 43 at the upper and lower ends of the adjustment window 42 are provided with threaded adjustment holes. The threaded head 32 is connected to the threaded adjustment holes to close the remaining smoke-collecting areas above and below the adjustment window 42. At the same time, the end plates 43 at both ends can also limit the adjustment stroke of the adjustment knob 31. The adjustment knob 31 is exposed inside the adjustment window 42 and can be inserted by the thumb to contact and rotate for adjustment, which has good operability.

[0039] Furthermore, in order to improve the smoothness of the movement of the adjusting sleeve 3 as it rotates with the thread, a guide plate 4333 is provided at the lower end of the adjusting sleeve 3. The guide plate 4333 is slidably sleeved on the base column 11, making full use of the outer circumferential surface of the base column 11 for movement guidance.

[0040] In one exemplary embodiment of this disclosure, when the spraying demand is not limited to lung-cleansing agents, such as the spraying demand of menthol agents that female smokers prefer for fresh breath, in order to support more spraying demands, this example provides implementations of single spraying and double spraying of two agents. Of course, based on the concept of this example, more than two agents can also be sprayed simultaneously, but this example will not show them one by one.

[0041] like Figure 3 As shown, two reagent bottles are set in the liquid placement area and two sets of spraying mechanisms 5 are configured. The two sets of spraying mechanisms 5 are connected to the same spraying needle tube 9 by a connecting joint 6. The connecting joint 6 has a T-shaped structure, with its opposite ends being liquid inlets, which are respectively connected to two liquid storage tanks 51. A one-way valve is set on the liquid inlet of the connecting joint 6 or the liquid outlet of the liquid storage tank 51.

[0042] A pressing groove is provided on the upper end face of the housing 4. The lower end of the pressing head 2 is slidably disposed in the pressing groove and is locked under the upper edge of the pressing groove. The two pressing heads 2 are arranged side by side in the pressing groove. The distance from the pressing head 2 to the upper end face of the housing 4 is one single pressure stroke L1. One single pressure stroke L1 corresponds to one pump of reagent volume.

[0043] Refer again Figure 1 and Figure 2 To facilitate simultaneous pressing, the pressing groove connects two pressing heads 2, which are positioned close together. The adjacent ends of their upper surfaces are provided with identical quarter-circle arc-shaped recesses. These two quarter-circle arc-shaped recesses combine to form a semi-circular recess adapted to the width of a thumb. When the thumb presses into this semi-circular recess, dual-liquid co-spraying is achieved. Pressing onto the high slope at the distal end of a single pressing head 2 allows for single-pressure, single-liquid spraying. Furthermore, as... Figure 2 As shown, the adjacent sides of the pressing head 2 can also be provided with tenons and tenons to ensure that the pressure applied to the middle of the semi-circular recess can still act synchronously on the two pressing heads 2 when there is a deviation in the pressure;

[0044] In addition, considering that excessive spray volume from a single cigarette will affect the taste of the filter, when spraying two reagents simultaneously, the spray volume of the co-spray should be controlled. Therefore, the semi-circular recess also has a potential spray volume function design. By designing the distance between the semi-circular recess and the upper end face of the housing 4, i.e., the double pressure stroke L2, the double pressure stroke L2 is equal to half of the single pressure stroke L1. In this way, it is ensured that the spray volume when pressed to the bottom is still one pump volume.

[0045] The directional words "up," "down," "side," "end," "middle," "inner," and "outer" mentioned in this article are based on... Figures 1-4 The orientation or positional relationship shown in the corresponding figures, or the orientation relationship in the state of use. These terms are mainly for the purpose of better describing the invention and its embodiments, and are not intended to limit the indicated device, element or component to having a particular orientation, or to be constructed and operated in a particular orientation;

[0046] Furthermore, the above figures are merely illustrative of the processes included in the method according to exemplary embodiments of the present invention, and are not intended to be limiting. It is readily understood that the processes shown in the above figures do not indicate or limit the temporal order of these processes. Additionally, it is readily understood that these processes may be executed synchronously or asynchronously, for example, in multiple modules.
