Description

1. Technical Field

[0001] The utility model belongs to the field of sanitation appliances, and relates to a device for wet extinguishing of cigarette butts, in particular to a convenient and portable device for extinguishing cigarette butts constructed by utilizing the principle of "instant extinguishing of cigarettes with micro-water", which can effectively solve the problems of potential safety hazards, environmental pollution, and high cost of use existing in traditional cigarette extinguishing methods and devices such as pressing or grinding, inserting into sand and gravel, and immersing in a water container, such as inability to extinguish completely, easy to continue burning, ash scattering, long-lasting smoke flow, easy to dirty hands, and difficult to clean, etc., and has the outstanding advantages of instant wet extinguishing, convenience and ease of use, safety, environmental protection, cleaning, and low cost of use and maintenance, and is widely applicable to municipal single-installed or attached cigarette extinguishing and cigarette butt recycling devices for garbage bins (tubes), cigarette butt extinguishing and recycling devices for smoking areas in office places, parks, markets, hotels, restaurants, and waiting (airport) halls, as well as cigarette extinguishing and cigarette butt treatment in public and private places such as homes and cars. 2. Background Technology

[0002] Smoking is not encouraged. However, due to social and historical reasons, there are still a large number of smokers, with more than 300 million smokers in my country alone. Smoking is an integral part of social life, with far-reaching impacts. It is not only a social abuse or a lifestyle or cultural habit, but also causes many safety, environmental and health problems, and the whole society has to pay a huge price for it.

[0003] The treatment of cigarette butts, including extinguishing, collecting, and cleaning, is an integral part or necessary link of the smoking phenomenon, and its technical solution is one of the important needs of the whole society to deal with the smoking problem. Municipal public garbage recycling equipment throughout the streets and alleys usually has indispensable cigarette extinguishing and cigarette butt recycling components. Subway entrances, stations, airports, docks, markets, parks, scenic spots, hotels, restaurants, office buildings, government agencies and other crowded places usually have special cigarette butt extinguishing and recycling equipment. Private residences and private cars are usually equipped with "ashtrays" and other forms of cigarette butt disposal appliances. It can be seen that cigarette butt extinguishing and storage devices are a type of sanitation equipment that is widely used and widely used in reality.

[0004] The burning of cigarettes is a flameless smoldering, the temperature reaches the ignition point but there is no flame, and smoke will be released. The key to the treatment of cigarette butts is to extinguish them, including extinguishing open flames and cooling them to a safe range. Completely extinguished cigarette butts are no different from ordinary garbage such as fruit peels and paper scraps, and can be "manipulated" and easy to clean. The temperature of a burning cigarette butt can reach 200 to 300°C. Although it is small in size, it poses a hidden safety threat and is a "full" fire source that can ignite most combustibles. Moreover, with the continuous improvement of tobacco companies, most cigarettes now have extremely strong continuous burning properties, that is, a lit cigarette can keep burning slowly under static conditions even if it is not sucked until its tobacco is burned out. Although this caters to the intermittent sucking characteristics of smoking, reduces the frequency of relighting due to self-extinguishing of cigarette butts, and is conducive to smoking, it weakens the self-extinguishing performance of cigarette butts, prolongs the self-extinguishing time, and increases the difficulty of actively and completely extinguishing cigarette butts. Burning cigarette butts are a bit "tricky" to discard or deal with because of their open flame, high temperature and "tenacious" burning ability. They cannot be ignored and thrown away easily like ordinary garbage, but require proper and comprehensive measures to extinguish them.

[0005] Common cigarette butt extinguishing methods, application scenarios and existing problems are as follows:

[0006] 1. Press or grind out. Municipal trash bins (drums) usually come with a relatively isolated and independent cigarette butt storage container made of flame-retardant material. At the entrance, there is often a mesh with holes made of the same material as the container, or simply a concave baffle, which is used to press or grind out cigarette butts. With the help of the mesh or baffle, the ash particles with open flames or extinguished cigarette butts produced by pressing and grinding cigarette butts can leak or slide into the cigarette butt storage container. If the user does not press to extinguish the cigarette butt but directly throws the burning cigarette butt into the storage container, the cigarette butt will continue to burn in the container until the tobacco is burned out and can also be extinguished; other public places have a press-and-grind smoke extinguishing device installed alone or attached to the garbage collection device. The structure and usage are roughly similar to the above-mentioned situations; the vast majority of "ashtrays" are just a storage container for cigarette butts and ashes. At the same time, because they are made of flame-retardant materials, they provide a place to safely crush or grind cigarette butts, making them both extinguishable and storeable. They are also simple in structure, easy to manufacture, and inexpensive, making them a widely used type of cigarette butt disposal tool. A more casual and lazy way to extinguish cigarettes is to throw the cigarette butts directly on the ground, then step on them once or twice to speed up the extinguishing process, or simply throw them without stepping on them, allowing the cigarette butts to burn out and extinguish themselves, and finally sweep the ground to collect and dispose of the cigarette butts. When handling cigarette butts in the manner described above, there are problems of varying degrees of environmental pollution and safety hazards, such as crushing cigarette butts that easily stain hands, splashing ash that is difficult to clean, the open flame of cigarette butts that cannot be extinguished, and smoke from subsequent burning. When using outdoor municipal smoke extinguishers, the "sparks" formed by crushing cigarette butts will fly in the wind, and the splashed ash will be scattered by the wind, which will expand the safety hazards and ash pollution to farther places.

[0007] 2. Extinguish by immersion or suffocation. When using an ashtray, in order to reduce the scattering of dry ashes, and also to solve the problem of being difficult to press and grind to extinguish cigarettes, easily dirtying hands, and preventing the air from being choked by the smoke that cannot be extinguished, and to achieve the purpose of simply and completely extinguishing cigarette butts, some water is usually put in the ashtray. When using it, just immerse the cigarette butt or its burning end directly in the water or dip it in the existing wet ashes or the cigarette butt that has absorbed water to quickly achieve the purpose of extinguishing; some smoke extinguishing devices for municipal purposes or public places also apply the aforementioned "wet extinguishing" principle, and set up water storage containers to immerse cigarette butts. Some garbage collection devices in open-air places will have an open cigarette butt immersion storage box on the top, and sanitation workers will add water and clean cigarette butts regularly. It seems that they can also collect and utilize rainwater from the sky for the purpose of extinguishing cigarette butts, and can reduce the workload of sanitation workers to add water; some hotels, restaurants, and office buildings have garbage cans on the top. A gravel box is set up to be used for extinguishing and storing cigarette butts. This is similar to the aforementioned device that uses a water storage container to extinguish cigarette butts, but instead uses gravel or other solid particles as the medium for extinguishing, storing and adhering ashes to cigarette butts instead of water. When in use, the cigarette butts can be inserted into the gravel or powder. The inserted medium can not only store the cigarette butts, but also isolate the open flame from the air, which will cause the burning end of the cigarette butt to suffocate and extinguish, and the ashes are mixed into the gravel or powder and are difficult to disperse. Using a closed container with a lid to collect and extinguish cigarette butts is also a common method. The cigarette butts are directly thrown into the container, and then the lid is closed and sealed. Even if there is still a small amount of air in the enclosed space, the cigarette butts can be kept burning for a short time, but the cigarette butts, ashes and the continued burning smoke flow are all enclosed in the container, with almost no impact on the environment, and the cigarette butts will soon be completely extinguished because the oxygen in the enclosed space is consumed to a thin or exhausted state. In the above, the container is not limited to a single style, including cups, plates, bottles, cans, boxes, glass, plastic, metal materials, regular or irregular shapes, and in terms of the principle of smoke extinguishing, all rely on medium immersion or air isolation. Although the various methods of dealing with cigarette butts described above seem simple, easy, safe and environmentally friendly, they still have problems such as unreliability, difficulty in cleaning, high maintenance cost, and poor user experience to varying degrees. The following is a brief analysis of each: When using water as a medium for "immersion extinguishing", water is required to extinguish open flames, and the unburned part of the cigarette butt and the filter will also absorb water. In order to facilitate the placement of cigarette butts, the water storage container is usually open, which leads to the problem of water evaporation and air drying. Under the combined effect, water consumption is relatively fast, and it is difficult to store water for a long time and maintain an effective and usable state with one water addition. It is necessary to frequently clean the garbage such as cigarette butts and ashes stored in the container and add water, otherwise the safety and environmental protection effect of the "wet extinguishing" method will be lost, and it will become a "dry extinguishing" device that is pressed or ground.Many open-top ashtrays installed on the top of municipal trash cans (drums) in open-air places often become dry due to untimely maintenance and watering, which not only makes it difficult to put out cigarettes, but also scatters the stored cigarette butts and ashes on the street under the natural wind. Cigarette butts that have not been extinguished just put in may even cause sparks and afterburning smoke to float around, which is a safety and environmental hazard. Some people who discard cigarette butts see that the water in the ashtray is dry and difficult to use, so they will hastily press and grind the cigarette butts and throw them into the trash can below, or even throw the burning cigarette butts directly into the can. The unextinguished cigarette butts will ignite when they encounter flammable garbage such as paper scraps, causing the trash can (drum) to continue to smoke or even catch fire, and finally burn the garbage recycling equipment beyond recognition. The completely soaked ashes will stick to the container tightly, and will easily form a hard surface after drying, which is time-consuming and laborious to clean and difficult to clean. In order to solve the problem of "immersion extinguishing", there is a kind of ash cleaning powder on the market. If you sprinkle a little in the ashtray, it will expand when it comes into contact with water, and it can remain moist for a long time. It can also effectively prevent wet ash from adhering to the ashtray, making the collected cigarette butts and ash easy to clean, but the use of this "consumable material" will still increase the cost of extinguishing cigarettes. When using "sand and gravel" or "solid powder" as the medium, the cigarette butts are generally cleaned together with the medium, that is: the medium is "one-time" use, so it is consumed quickly and more, and the weight and cost of cleaning and transportation will also increase; if the medium is to be reused, the cigarette butts inserted in it need to be separated or picked out one by one, which is more time-consuming and laborious; if in order to make full use of the medium, if a large number of cigarette butts are already inserted in it, the newly inserted cigarette butt may be close to the inserted cigarette butt, so that the new cigarette butt cannot be fully "buried" by the medium, but there are more gaps around it, which will cause problems such as slower extinguishing, aggravated afterburning, and more afterburning smoke flow, which seriously affects the extinguishing effect and user experience. The method of using a "sealed container with a lid" to extinguish cigarettes is only suitable for private occasions. If it is used in municipal or public places, the action of opening and closing the lid will be a bit troublesome. Moreover, in the case of high-frequency use, if the later person opens the lid to discard the cigarette butts, the cigarette butts in the container have not been completely extinguished or the extinguished smoke has not been completely settled, then opening the lid will cause the smoke in the container to escape to the outside space and choke the user and pollute the environment. Even if the existing cigarette butts in the container have all been completely extinguished and the smoke has all been completely settled, when the lid is opened, there will still be a strong smell of smoke released and choking, so the user experience is poor.

[0008] 3. Extinguishing smoke through holes. Some ashtrays are provided with vertical columnar smoke-extinguishing holes or smoke-extinguishing tubes on the side walls. The upward end of the hole is used as a cigarette butt insertion port, while the lower end is blocked, or a small hole is opened for the ash to leak out. The inner diameter of the hole is usually only slightly larger than the outer diameter of the cigarette butt. The smaller the gap between the two, the more conducive it is to extinguish the cigarette butt. This structure allows the cigarette butt to be quickly extinguished in a short time after insertion. After that, the cigarette butt needs to be manually pulled out from the insertion port and then discarded into the ashtray. The principle of smoke extinguishing is as follows: the filter end or the pinched end of the cigarette butt inserted into the hole forms a blockage to the insertion port, so that the burning end of the cigarette butt is blocked in the narrow space in the hole, making it difficult to form air convection. At the same time, the high temperature of the burning end of the cigarette butt causes most of the air in the blocked space to expand and discharge, and consumes the oxygen in the remaining small amount of air, thereby forming a severely oxygen-deficient air layer near the burning end. First, The burning of the outer layer of the burning end of the cigarette butt is difficult to continue due to lack of oxygen, so it cools down and extinguishes. Under the condition that it is difficult to form air convection, the extinguished outer layer together with the adjacent oxygen-deficient layer will block the oxygen-rich air from farther away from entering the inner core of the cigarette butt, thereby further weakening the continued burning of the fire core. In addition, the "high temperature section" formed by the burning end, which still has residual heat despite the cooling, together with the heated hole wall, will block the approach of air from farther away, thereby hindering the oxygen replenishment of the cigarette butt fire core. Under the combined effect, the fire core inside the cigarette butt will be extinguished faster due to lack of oxygen. Factors affecting the extinguishing speed of the aforementioned cigarette butt include: the material of the hole, the size of the gap between the inner wall of the hole and the outer periphery of the cigarette butt, and the size, thickness or depth of the small hole opened at the bottom of the hole for the ash to leak out. During the process of inserting the cigarette butt, the ash leaking out of the small hole is conducive to the discharge of the heat-expanded air, thereby accelerating the reduction of the oxygen content in the space in the hole that blocks the burning end of the cigarette butt, which is beneficial to accelerating the extinguishing of the cigarette butt. However, the existence of the small hole provides a channel for replenishing the air and oxygen needed for the cigarette butt to continue burning, which will delay the extinguishing of the smoke. The best solution is that the small hole is one-way exhaust but cannot replenish air, but this is generally not done because the structural cost is high. Since the air discharged is heat-expanded and has a certain pressure, and when replenishing air, the natural air outside the hole is unpressurized, therefore, increasing the depth or thickness of the small hole, increasing the distance between the smoke-extinguishing blocked space and the external space of the hole, and increasing the obstacles or difficulty of replenishing air can also achieve a good effect of promoting the advantages and suppressing the disadvantages between the favorable effects of exhaust and the negative effects of replenishing air, and is therefore a simpler and more commonly used method. Generally speaking, choose porous materials with good air tightness and less thermal expansion or deformation, reduce the gap between the inner wall of the hole and the outer periphery of the cigarette butt, and make the size and depth of the small holes for ash leakage meet the requirements of "smooth drainage, obstruction and repair" as much as possible. These are feasible solutions or effective measures to shorten the smoke extinguishing time and improve the efficiency of smoke extinguishing.Under the condition of properly controlling various influencing factors, the hole-type smoke extinguishing method can achieve a time of less than 10 seconds or 5 seconds from the insertion of the cigarette butt to complete extinguishing (i.e., the afterburning stops and cannot reignite). Compared with the pressure-grinding method, the smoke extinguishing process is easier and simpler, and almost no ash splashing will be generated. In addition, the shape of the cigarette butt after extinguishing is complete and easy to take care of. Therefore, it can be regarded as a relatively ideal smoke extinguishing solution. The problems it has are: First, when inserting the cigarette butt "closely" into a hole whose inner diameter is only slightly larger than the outer diameter of the cigarette butt, a relatively precise "aiming" or "aligning" ability is required. This requires operational requirements for the user and will weaken its "ease of use". If there is a slight deviation during insertion, it will cause ash splashing and sparks flying at the entrance, just like the pressure-grinding smoke extinguishing method. Even if the entrance is made into a "trumpet-shaped" shape, it is difficult to completely solve the problem, because unless the cigarette butt can be inserted straight into the hole, otherwise, the pressure-grinding smoke extinguishing will occur at the "trumpet-shaped", and if the hole is enlarged to improve ease of use, the hole will cause the cigarette butt to be extinguished. The inner diameter of the hole. Since the smoke-extinguishing effect is very "sensitive" to the size of the gap between the inner wall of the hole and the outer periphery of the cigarette butt, it will significantly prolong the time required from the insertion of the cigarette butt to its complete extinguishing. Even an inner diameter that exceeds the limit will cause the hole to lose its ability to quickly extinguish smoke. Second, there is a delay or time difference from the insertion of the cigarette butt into the hole to its complete extinguishing. During this period, the user cannot intuitively see the status of the cigarette butt and is unclear whether the cigarette butt has been completely extinguished. In the absence of effective prompt information, it is difficult to judge when to take out the cigarette butt and discard it into the ashtray. In situations where the smoke extinguisher is used exclusively for private use, this does not seem to be a problem, because after inserting the cigarette extinguisher into the hole, you can just leave it alone and there is plenty of time to extinguish the cigarette. You can take out the previous cigarette butt when you are free or need to extinguish a new cigarette butt. However, in public places, especially in situations where the smoke extinguisher is used frequently, the cigarette butt inserted in the hole before is taken out by the subsequent user, or the user needs to wait on the spot for his or her cigarette butt to be extinguished and take it out and discard it before leaving. In this case, the delay in smoke extinguishing becomes a problem, because it is very likely that the previously discarded cigarette butt that has been taken out has not stayed in the smoke extinguishing hole for a long time and has not been completely extinguished. Such a cigarette butt will continue to burn and emit a choking smoke flow, which is almost like being directly discarded without being extinguished. The hole smoke extinguishing measure will appear to be ineffective; thirdly, because there is a delay in smoke extinguishing, rather than immediate and intuitive complete extinguishing, a small amount of smoke flow will still be generated. When used in municipal open-air windy occasions, or when the user leaves immediately after inserting the cigarette butt into the hole, there are still safety risks and hidden dangers, and it is still difficult for people to be completely assured.

[0009] The above is a general description of the various known smoke extinguishing methods and their characteristics and advantages and disadvantages. The technical features of other various smoke extinguishing methods and the instruments used can all be attributed to the above three categories of smoke extinguishing methods, or their variations.

[0010] Putting out cigarettes may seem like a trivial matter in daily life, but small cigarette butts can lead to big problems. Billions of cigarette butts are produced in China every day, and the world's 1 billion "smokers" produce a total of 5.7 trillion cigarette butts every year. There are countless safety risks, environmental problems and heavy sanitation burdens. Although it is a commonplace matter, it does not mean that there are no problems and no need for improvement and perfection. The smoking extinguishing method that hundreds of millions of people are accustomed to may not be the best technical solution.

[0011] An ideal smoking extinguishing solution should be convenient and easy to use, while ensuring safety, environmental protection, ease of use, low cost, high reliability, and easy maintenance. It should also distinguish the application characteristics of different occasions and solve the problem of cigarette butt extinguishing in a targeted manner. For example, personal smoking extinguishers should focus on solving the problems of easy portability and ease of use. Smoking extinguishers for private occasions such as home and car can have a simpler structure and leave more links to the user to complete. However, whether indoors or outdoors, as long as it is a smoking extinguisher in a public place, it is better to be more complicated than the device itself, but it should be as convenient, easy to use, and reliable as possible to reduce the dependence on the user's quality level or good cigarette butt disposal habits.

[0012] In fact, the burning end of a cigarette butt is only the size of a soybean or peanut, and has no flame. It can be extinguished immediately and completely with just a drop of water of the same size, and it can eliminate the problems of continued smoke flow, ash scattering, and difficulty in cleaning. There are no special technical difficulties. The reason why there are various problems with the known methods of extinguishing cigarettes is probably because the problem of extinguishing small cigarette butts is not taken seriously, and there is no carefully considered plan for it, so it appears to be extensive and "makeshift". The idea of ​​"extinguishing cigarettes with a drop of water" has outstanding advantages over the "dry" extinguishing scheme that does not use water, but the price is that "water" as a "consumable" is used. At the same time, it is necessary to solve technical problems such as where the water comes from, where and how it meets the "fire" of the cigarette butt, how to control the water used to extinguish the cigarette to be just "a drop" that is neither too much nor too little, and how to prevent abnormal conditions such as freezing of waterways.

[0013] This application will use the idea of ​​"a drop of water extinguishing cigarettes" to solve the existing application problems and provide a new technical solution for a cigarette butt wet extinguishing device. III. Summary of the invention

[0014] The purpose of the utility model is to solve the technical problems existing in water supply control and water-based cigarette extinguishing based on the idea of ​​"one drop of water extinguishing cigarettes", and to provide a technical solution of a cigarette butt wet extinguishing device that is safe, environmentally friendly, reliable, easy to use and highly economical, thereby making it easier and more flexible to extinguish cigarette butts, and significantly improving the level of cigarette extinguishing and cigarette butt handling in the whole society.

[0015] The purpose of the utility model is achieved as follows: a device for wet extinguishing of cigarette butts, characterized in that: a water supply device is fixedly connected to a cigarette butt storage container and / or a water retention device as a whole or can be assembled and connected as a whole through a movable interface or have a fixed relative position relationship when used with each other, the water supply device gives out cigarette extinguishing water through its water outlet, and the amount of cigarette extinguishing water given out each time does not exceed 1 ml, and its water supply process is manually controlled or controlled by a circuit, or the air intake and water discharge process is naturally triggered when the cigarette butt is dipped and sucked at its water outlet, The water outlet discharges the smoke-extinguishing water onto the path of cigarette butts discarded into the cigarette butt storage container, or discharges it onto a water retaining device outside the water outlet, so that the discharged smoke-extinguishing water can intercept or track the moving cigarette butts, or can be dipped and inhaled by the cigarette butts. The water retaining device is a smoke-extinguishing pipe, a smoke-extinguishing groove, or a smoke-extinguishing platform where the smoke-extinguishing water meets the cigarette butts, or a groove or pit for carrying or accommodating the discharged smoke-extinguishing water, or a convex mouth for hanging water droplets formed by utilizing the surface tension of water, or a platform or boss for gathering water droplets.

[0016] The water supply device includes a mechanical plunger pump or a push-type suction pump core, or includes an electric water pump or an electromagnetic pump, or includes a pressurized water source and a water outlet control valve, or includes a water column affected by gravity and a water outlet affected by atmospheric pressure.

[0017] The circuit includes a cigarette butt detection circuit and a water pump control circuit. The detection device or probe included in the cigarette butt detection circuit is sensitive to the temperature of the burning end of the cigarette butt, or is sensitive to the shielding effect formed when the cigarette butt passes by, or is sensitive to the distance between itself and the cigarette butt, or is sensitive to the hand holding the cigarette butt. When the sensitive object or sensitive condition detected appears, the cigarette butt detection circuit will be triggered to enter the automatic control process of giving out smoke-extinguishing water. The water pump control circuit performs automatic start and stop control of the water pump that gives out smoke-extinguishing water. Its start is controlled by the cigarette butt detection signal, and its shutdown is controlled by the automatic delay circuit or the cigarette butt detection signal. The water pump action controlled by it and the duration of giving out smoke-extinguishing water are within 2 seconds.

[0018] The protruding mouth is a downward convex surface in the shape of a pot bottom, or a downward convex arc with high sides and a low middle, or a suspended point supported by an upper object or connected to an upper object.

[0019] The water supply device dispenses cigarette extinguishing water in batches under the drive or control of a reciprocating mechanical moving part or an intermittent rotating device, or dispenses cigarette extinguishing water during the natural air intake and water discharge process caused by dipping a cigarette butt into the water outlet. Each complete reciprocating or intermittent process, or each complete process of dipping a cigarette butt into the water outlet, constitutes one water supply.

[0020] The water supply device is fixedly connected to the water retention pit as a whole, and smoke-extinguishing water is supplied to the pit through a press-type suction pump core for cigarette butts to dip and suck. The water supply device is also provided with a movable interface device that can be connected to a lighter or a cigarette box as a whole, so that it can be carried around and used to extinguish cigarettes at hand.

[0021] A smoke extinguishing tube for cigarette butts to pass through is provided at the entrance or entry passage of the cigarette butt storage container, and a photoelectric detection device and a nozzle are sequentially arranged in the direction from the entrance to the exit, and the two are connected through a circuit. The photoelectric detection device is outside the entrance of the smoke extinguishing tube or on the side wall of its inner cavity, and controls the start and stop of the nozzle by detecting the position of the cigarette butt. The nozzle is on the side wall of the inner cavity of the smoke extinguishing tube or outside its outlet, and is used to spray water mist, water column or discrete water droplets. The working power supply of the circuit is a battery or a power grid.

[0022] The water supply device is connected to the water retention groove as a whole, and the water outlet of the water supply device is on the groove. The groove can rotate around a fixed fulcrum under the action of an external force. The water supply valve is opened or the liquid is pressurized by the rotation, causing the cigarette extinguishing water in the liquid container to be discharged through the water outlet and meet the cigarette butt touching the groove. Moreover, the return stroke of the groove after rotation is driven by the reset rebound force of the spring.

[0023] The water supply device and the water retaining protruding spout are both attached to the garbage collection device, and the cigarette extinguishing water can be supplied to the protruding spout by stepping on it or pressing it with hands to form hanging water drops for being dipped and sucked by cigarette butts.

[0024] The water supply device includes a water storage container, which is arranged above the entrance of the cigarette butt storage container. The water storage container is closed at the top and has a water outlet at the bottom, and a water column under the action of gravity is formed in the inner cavity. The water outlet is outside the water outlet and is close to the water outlet. Under the action of liquid surface tension and external atmospheric pressure, sitting water droplets are formed on the water outlet for cigarette butts to dip and inhale. After dipping and inhalation, new sitting water droplets will automatically form on the water outlet.

[0025] The utility model is based on the concept of "instant extinguishing of cigarettes with a little water". The device can be used as an accessory of an ashtray, fixedly or movably connected to the ashtray to increase the convenience of extinguishing cigarette butts. It can also be attached to a municipal garbage collection device as a front device or entrance device of its cigarette butt collection component. It can also be constructed into a separate special sanitation appliance for cigarette butt disposal and collection by adding a cigarette butt collection container, which is used for cigarette butt treatment in private or public places. The shell or overall appearance or shape of the smoke extinguishing device and the cigarette butt collection container can be made into an animal or plant image, or an image of a production and living necessities utensil, or a geometric shape, or an abstract artistic image, to enhance its recognition or use suggestion or sensory interest and affinity attraction. It is characterized in that: the water supply device includes a water storage container, which is a soft-wall container or a hard-shell container or a pressure container or a container including a partial soft wall, or a container including more than one accommodating chamber. The water storage container has an openable water replenishment port, or a valve-type filling port, or a one-way filling plug. The movable interface device is an inlay or bayonet or hinge or ring or magnetic device that can be movably connected to the cigarette lighting device or the cigarette box for packaging cigarettes. The water storage container or water supply control device is connected to the cigarette butt storage container as a whole. The water supply device has a water return function, or includes a water return device. After each burst of water supply, the water remaining in the water supply passage and not carried away by the cigarette butts can be returned to the water storage container to prevent it from blocking the water supply passage or hindering the next supply of smoke-extinguishing water due to freezing or solidification. The smoke-extinguishing pipe is used as the entrance of the cigarette butt storage container and is connected to it as a whole. The cigarette butt storage container has one or more entrances, or one or more smoke-extinguishing pipes are arranged at the same entrance. The pit is a platform with a large mouth and a small bottom, or a sphere or ellipsoid of no more than half, and its water inlet is at the bottom of the pit, or on the side wall of the pit, or suspended above the pit mouth. The pit depth of the pit does not exceed 1 cm, the bottom area does not exceed 1 square cm, and the volume does not exceed 1 ml.

[0026] The nozzle is on the side wall of the smoke extinguishing tube. From the moment the photoelectric detection device detects the cigarette butt, it sprays a cone-shaped water mist until the cigarette butt passes through the detection area along its length. The nozzle is outside the outlet of the vertical smoke extinguishing tube. After the photoelectric detection device detects the cigarette butt, the nozzle is controlled to open and close so as to spray discrete water droplets vertically upward toward the entrance of the smoke extinguishing tube to meet the cigarette butt entering the smoke extinguishing tube. After the cigarette butt meets water, it passes through the smoke extinguishing tube and leaves through the gap between the nozzle and the edge of the exit of the smoke extinguishing tube. The photoelectric detection device is on the side wall of the smoke extinguishing tube or outside the entrance of the smoke extinguishing tube. When the cigarette butt has been blocked from the detection light and is out of the blockage, the nozzle is immediately or after a delay controlled to start spraying, and then after a continuous spraying period, the nozzle is controlled to stop spraying. The continuous spraying period of the nozzle is limited to no more than 0.01 seconds, 0.1 seconds, 0.5 seconds, 1 second or 2 seconds. The photoelectric detection device uses the cigarette butt starting to block the detection light and / or stopping blocking the detection light as the timing or trigger factor for changing the control state. When the detection light is blocked again, it enters a new round of spray-out control cycle or process.

[0027] The groove is a force-applying handle of a manual water-pressing device. Pressing a cigarette butt placed in the groove with a finger can cause the groove to rotate, and the water pressed out by the rotation can meet the cigarette butt in the groove and extinguish it. The pressed water flows out from the wall or end of the groove, and the water outlet is in the direction of the lit end of the cigarette butt, so that the water can flow along the inclined groove under the action of gravity and extinguish the lit end of the cigarette butt, or the water outlet is just in the groove part where the lit end of the cigarette butt is placed, so that the water can directly pour on the lit end of the cigarette butt. The groove is a tube or groove with a closed side wall, or a tube or groove with a partially open side wall.

[0028] Antifreeze is added to the smoke extinguishing water. The water supply device is wrapped with heat-insulating material. IV. Description of the drawings

V. Specific implementation methods

[0041] Figure 1 , Figure 2 , Figure 3They are respectively the front view, top view and bottom view of the partial structure of Example 1. Example 1 is a specific implementation method that combines the smoke extinguishing device with the cigarette lighting device to achieve the purpose of carrying it with you at any time and extinguishing the cigarette at hand. The inner cavity of the water storage container shell 3 is divided into a smoke extinguishing water containing chamber 1 and a smoke smell regulator containing chamber 4 by a water storage container inner cavity partition plate 14. The two containing chambers are respectively provided with a push-type spray pump core 2, and the end thereof facing the inside of the chamber is connected with a suction tube 13 for sucking the liquid in the chamber, and the end facing outside the chamber is connected to the water storage container shell 3 to close the internal space of the chamber. The lower end of the spray pressing rod 7 is connected to the piston inside the push-type spray pump core 2, and the upper end thereof is connected to the spray pressing plate 8. By pressing the spray pressing plate 8 to the push-type spray pump core 2, the liquid in the cavity can be sprayed out. The push-type spray pump core 2 is equipped with a reset spring, which can return the spray pressing rod 7 and the spray pressing plate 8 to their original positions after a burst of water supply. At the same time, due to the reset of the internal piston, the water retained in the water outlet passage can also be "sucked" back into the piston chamber to achieve water return and emptying of the end section of the water outlet passage. The press-type liquid spray pump core 2 can be a mechanical piston pump with a bottom valve, or it can be a common miniature hand pressure pump for pressing and sucking the fluid in the barrel or bottle, such as: a spray pump used in a perfume bottle or other hand-held spray bottle, and a hand pressure suction pump used in a container mouth such as a detergent bucket or a shampoo bottle for manually pressing and ejecting the content fluid. However, this embodiment does not require the smoke-extinguishing water to be sprayed into a mist, so it is necessary to slightly modify the water passage of the aforementioned spray pump, and only use its suction pump core, and the water outlet only needs to be able to flow out smoothly. Both accommodating chambers are also provided with internal threaded filling ports on the water storage container shell 3, which are blocked by a smoke-extinguishing water filling port bolt 17 and a smoke smell regulating water filling port bolt 18 respectively. In order to facilitate the manual operation of the opening and closing of the filling port, both bolts are provided with a bolt hand-tightening cap 19. Of course, it is also possible to adopt a bolt form that requires the use of tools such as a screwdriver or a wrench to operate the opening and closing. The side used to spray smoke-extinguishing water has an overall structure similar to that of a "lighter", except that it "sprays out" water instead of "fire". In other words, it is a "water pump".In terms of specific structure: the liquid spray pressing plate 8 is exposed and suitable for finger operation. The bottom of the piston chamber of the press-type liquid spray pump core 2 is connected to a water outlet pipe 9, which releases the pressed smoke-extinguishing water into the water pit 5 through the water outlet 10. The water pit 5 is semi-ellipsoidal as a whole, or a platform with a large mouth and a small bottom. The pit depth does not exceed 1 cm. The water outlet 10 is at the bottom of the pit, or on the side wall of the pit, or suspended above the pit mouth. The arc bottom 6 of the water pit is ellipsoidal and connected to the water storage container shell 3, or directly as a part of the water storage container shell 3. The water pit cover plate 11 covers the pit mouth of the water pit 5 and is connected to the liquid spray pressing plate 8 through the rotating shaft 12, thereby limiting It moves downward to pressurize water. Only when the water retaining pit cover 11 is rotated around the rotating shaft 12 to avoid the obstruction of the water retaining pit 5 and the water storage container shell 3 to its downward movement, that is, the water retaining pit cover 11 is covered on the liquid spray pressing plate 8, can the connecting body of the water retaining pit cover 11 and the liquid spray pressing plate 8 be pressed to realize water pressure and water discharge. In this case, the water retaining pit 5 is open and water is obtained, and cigarette butts can be inserted into the water to dip in the water for the purpose of extinguishing the cigarette. After the cigarette butt is extinguished and the connecting body of the water retaining pit cover 11 and the liquid spray pressing plate 8 is reset, the water retaining pit cover 11 can be manually rotated again to cover the pit mouth of the water retaining pit 5 to prevent the cigarette extinguishing water remaining in the pit from flowing out. On the side used for spraying the smoke smell regulator, an injection needle 16 is connected to the spray pressing plate 8, and the piston chamber of the press-type spray pump core 2 is connected to the hollow core of the injection needle 16 through the hollow core between the spray pressing rod 7 and the spray pressing plate 8 in turn, so that the pressed smoke smell regulator or water can be ejected from the needle. The injection needle 16, the spray pressing plate 8 and the spray pressing rod 7 are all located inside the cylindrical cigarette butt filling chamber 15, and the side wall of the cigarette butt filling chamber 15 is connected to the water storage container shell 3, or is directly a part of the water storage container shell 3. A cigarette butt filling chamber cover 21 is provided on the entrance and exit of the cigarette butt filling chamber 15 to prevent debris from entering. It is connected to the water storage container shell 3 through a rotating shaft 12 and can rotate around the rotating shaft 12 to open and close the cigarette butt filling chamber 15. Insert the filter end of the cigarette, and the injection needle 16 will penetrate into the filter. When the top of the filter touches the liquid spray pressing plate 8, the penetration depth will no longer increase. Continue to insert and press the cigarette, and press the liquid spray pressing plate 8 to allow the smoke smell regulator or water to be injected into the cigarette or its filter through the injection needle 16. Its function is similar to the taste regulating marbles placed in the filters of some currently sold cigarettes. The oil or preparation released by squeezing them can be mixed into the smoke flow to adjust its taste. Compared with the existing method of placing marbles when manufacturing cigarettes and their filters, the scheme of adding smoke smell regulators in this embodiment is simpler and more flexible, and users can choose and change the type of regulators at will. An adjustable cable tie ring 20 is provided on the side of the water storage container shell 3, which is used to be movably connected to a lighter 22 or a cigarette box for packaging cigarettes. The adjustable cable tie ring 20 is a ring made of a cable tie. By tightening or loosening the cable tie, the size of the ring can be conveniently adjusted, making it convenient to connect with different carry-on objects to form a portable interface.In this embodiment, the adjustable cable tie ring 20 may be omitted, and the lighter 22 may be directly integrated with the water storage container shell 3. However, the refilling of liquid fuel used in general liquid fuel lighters is dangerous and requires special tools and professional personnel to operate, and general users can hardly refill it by themselves. Therefore, ordinary liquid lighters are generally discarded after the fuel is used up, and it is difficult to reuse them by self-refilling. However, the "water lighter" and smoke smell regulating device provided in this embodiment are completely reusable. If it is integrated with a liquid fuel lighter that is difficult to reuse, it will cause a waste of resources. However, if it is integrated with a reusable lighter that can be refilled with gas fuel by itself, it is completely feasible.

[0042] Figure 4It is a partial structural diagram of Example 2. Example 2 is a specific implementation method of using a photoelectric detection device combined with a nozzle to spray extinguish cigarette butts in a hole. A cigarette butt storage trumpet 28 is provided at the entrance of the smoke extinguishing tube 23 through which cigarette butts can pass under the action of gravity, so that cigarette butts can enter. The exit of the smoke extinguishing tube 23 is opposite to the small opening at the upper end of the platform-shaped mouth cover 37. Two to four tension rods 39 are connected to the platform-shaped mouth cover 37, all of which are connected to a collision block or collision plate 38 with a pit in the middle, so that it is suspended in the air and is vertically below the exit of the smoke extinguishing tube 23. The cigarette butt can fall onto the collision block or collision plate 38 through the small opening at the upper end of the platform-shaped mouth cover 37, and after it rebounds or changes the falling direction, it falls into the cigarette butt storage tube 36. In the direction from the entrance to the exit of the smoke extinguishing tube 23, a photoelectric switch 24 and two or two groups of nozzles 25 are provided on the side wall of the smoke extinguishing tube 23 in sequence. The two nozzles 25 are respectively located at The two opposite sides of the side wall of the smoke extinguishing pipe 23 are flush along the radial direction of the smoke extinguishing pipe 23. A single or a single group of nozzles can also be set on only one side, and the nozzles are all directed along the radial direction of the smoke extinguishing pipe 23 and point to the axial position inside the smoke extinguishing pipe 23. The two nozzles 25 are connected to the water outlet 30 of the water pump via the water supply pipe 9, and the photoelectric switch 24 and the water pump 29 are electrically connected to the control circuit 26 through the control line 27. The water pump 29 is in the water tank 32, and the pump water inlet is provided with a water pump water inlet filter 31. The upper part of the water tank 32 is provided with a filling port 33, and the lower part near the bottom of the tank is provided with a sewage outlet 35. The side wall of the water tank 32 is provided with a light-transmitting water level observation window 34, which is used to visually observe the water level in the tank and the silt status at the bottom of the tank, and to prompt filling and desilting. Since the thickness of general cigarettes is divided into regular cigarettes, medium cigarettes and slim cigarettes, the corresponding outer circumferences are 24.5mm, 20mm and 17mm respectively. Therefore, in order to meet the needs of extinguishing cigarette butts of different thicknesses and to ensure the effectiveness and water-saving of extinguishing cigarettes, the inner diameter of the smoke-extinguishing tube 23 is usually selected between 8mm and 12mm. Of course, if the smoke-extinguishing device is only for cigarettes of a specific thickness, the inner diameter of the smoke-extinguishing tube 23 can also be made only slightly larger than the diameter of the specific cigarette, and the diameter margin is generally controlled between 2mm and 5mm. If you are not careful when sending cigarette butts into the smoke extinguishing tube 23 with a narrow inner diameter by hand, the cigarette butts may be bent and deformed, which will prevent them from passing through the straight smoke extinguishing tube 23 smoothly. Therefore, in order to facilitate the delivery and ensure that the cigarette butts enter the smoke extinguishing tube 23 straightly, the present embodiment provides a cigarette butt storage bell mouth 28, which is used as a guide for the delivery of cigarette butts. If the cigarette butts entering the bell mouth cannot directly and smoothly enter the smoke extinguishing tube 23 due to angle deviation, you only need to gently flick its end to test and adjust its direction angle, so that it can be easily delivered.The photoelectric switch 24 is of diffuse reflection type, through-beam type or "U"-shaped groove type. The rays emitted by its light-emitting diode enter the phototransistor through a certain area inside the smoke-extinguishing tube 23, or together with the reflection from a certain area on the inner wall of the smoke-extinguishing tube 23. When the cigarette butt entering the smoke-extinguishing tube 23 reaches the area through which the rays pass and changes its path due to blocking the rays, the phototransistor changes its circuit state accordingly due to the change in the amount of rays received. Similarly, when the cigarette butt leaves the area through which the rays pass, the phototransistor will also change its circuit state due to the change in the amount of rays received. The area through which the rays pass and which can cause the phototransistor circuit state to change is the detection area of ​​the photoelectric switch 24. In this embodiment, when the control circuit 26 receives a signal indicating that a cigarette butt enters the smoke extinguishing tube 23 and causes the state of the light-controlled triode circuit in the photoelectric switch 24 to change, the control circuit 26 will immediately start the water pump 29, driving it to provide pressurized smoke extinguishing water to the nozzle 25 through the water pump outlet 30 and the water supply pipe 9. The nozzles 25 spray out conical water mist, and the water mist sprayed from both sides will quickly fill the smoke extinguishing tube section where the nozzles are located. When the cigarette butt passes through the detection area of ​​the photoelectric switch 24, the spraying continues until the tail or upper end of the cigarette butt leaves the detection area of ​​the photoelectric switch 24, causing the state of the light-controlled triode circuit in the photoelectric switch 24 to change again. When the control circuit 26 receives a signal indicating that the control circuit 26 immediately shuts down the water pump 29, causing the nozzle 25 to stop spraying. The total time it takes for a cigarette butt to pass through the entire smoke-extinguishing tube 23 under the action of gravity is only in the millisecond level. During this process, it is necessary to ensure that the burning end of the cigarette butt can pass through the smoke-extinguishing tube section that is spraying water mist, or at least ensure that the part near the burning end of the cigarette butt can pass through the smoke-extinguishing tube section filled with water mist and can be attached with smoke-extinguishing water sufficient to extinguish the burning end, so that the cigarette butt is either sprayed out immediately, or when it touches the collision block or collision plate 38, the water droplets attached to the surface of the filter or the cigarette butt body quickly slide down to the burning end due to the impact and completely extinguish it. The collision block or collision plate 38 is also used to store the smoke-extinguishing water dripping from the smoke-extinguishing tube 23. When the burning end of the cigarette butt hits the collision block or collision plate 38 downward, it can ensure that the burning end can touch the smoke-extinguishing water and be reliably extinguished. The two nozzles 25 spray water mist from both sides to ensure that the corresponding two sides of the cigarette butt can be sprayed with water mist, thereby ensuring reliable extinguishing. There will be a slight delay from the time when the lower end of the cigarette butt triggers the control circuit 26 to start the pump to the time when the nozzle 25 sprays water mist. Ideally, after this delay, the lower end of the cigarette butt just reaches the location of the nozzle 25 and is sprayed by the water mist.Even if the water mist has been sprayed out before the lower end of the cigarette butt arrives, since the nozzle 25 sprays the water mist in the radial direction of the smoke extinguishing tube 23, the spatial distance in this direction is very small, and the water mist will soon reach the inner wall of the smoke extinguishing tube 23 in its direction of travel and be blocked by it and rebound, so that the movement path of the water mist presents a tortuous state of traveling along the radial direction of the smoke extinguishing tube 23 and falling along the axial direction of the smoke extinguishing tube 23 due to gravity, while the cigarette butt only performs a linear free fall motion along the axial direction of the smoke extinguishing tube 23, so the cigarette butt can still "catch up" with the water mist and achieve "water and fire meet". The extreme situation that needs to be avoided is: the cigarette butt has fallen to a position lower than the nozzle 25, but the water mist has not been sprayed out, or the cigarette butt cannot "catch up" with the water mist and cannot achieve "water and fire meet". The distance between the nozzle 25 and the photoelectric switch 24 along the axial direction of the smoke extinguishing tube 23 is generally controlled to be less than 3 cm. If the distance is too small, the sprayed water mist may splash onto the "window" of the photoelectric switch 24 for emitting and receiving rays or light, thereby hindering the normal operation of the photoelectric switch 24, or after the delay of spraying, the cigarette butt has fallen below the nozzle 25 and missed the "water-fire encounter"; on the contrary, if the distance is too large, it is possible that the cigarette butt has not yet "caught up" with the water mist and has already fallen to the bottom, which will also cause the smoke extinguishing to fail. This is the principle of selecting the distance between the nozzle 25 and the photoelectric switch 24 in this embodiment. Of course, the logic of the photoelectric switch 24 and the nozzle 25 associated with the control circuit 26 can also have other options, for example: when the cigarette butt has been blocked from the detection light and is out of the blockage, the nozzle is controlled to start spraying immediately or after a delay, and then the nozzle is controlled to stop spraying after a continuous spraying period. In order to prevent abnormal spraying such as continuous water spraying from the nozzle 25 due to cigarette butts stuck in the smoke extinguishing tube 23, an upper limit can be set for the continuous spraying time in the control circuit 26, and 0.01 seconds, 0.1 seconds, 0.5 seconds or 1 second can be selected as the limit value, until the stuck cigarette butts are cleared and the detection light of the photoelectric switch 24 is blocked, and then the "detection-water spraying" cycle or process is allowed to proceed normally again. The control circuit 26 includes a 555 timer or a single-chip microcomputer to realize the control logic, and can also be realized simply by a combinational logic circuit or a sequential logic circuit. The working power supply of the control circuit 26 is a battery or a power grid.In this embodiment, a suspended collision block or collision plate 38 with a pit in the middle is arranged inside the platform-shaped mouth cover 37 and vertically below the outlet of the smoke extinguishing tube 23. It has at least three functions: first, when the burning end of the cigarette butt is not sprayed with water mist but the filter or cigarette head in the vicinity is attached with water droplets, the collision of the cigarette butt with the collision block or collision plate 38 makes the water droplets attached to the surface of the filter or cigarette head in the vicinity be "shaken off" and quickly drip down to the burning end of the cigarette butt to extinguish it; second, when the cigarette butt fails to "catch up" with the water droplets that fall early in the smoke extinguishing tube and the smoke extinguishing fails, The water droplets that fall prematurely will be temporarily stored in the pit in the middle of the collision block or collision plate 38, and the cigarette butts that arrive later will first "pierce" the pit with their burning end and be extinguished by water, which is equivalent to an effective "remedy" for the "error" or "deviation" of extinguishing the cigarette in the smoke extinguishing tube; thirdly, the collision block or collision plate 38 plays a role in "distributing" the falling cigarette butts to the surrounding areas inside the cigarette butt storage tube 36, which can avoid the unfavorable situation that the cigarette butts fall into the middle part of the storage container and accumulate into a "hill" with a pointed end, and then cause the "hill peak" to block the outlet of the smoke extinguishing tube, which can improve the utilization rate of the internal space of the cigarette butt storage tube 36.

[0043] Figure 5 , Figure 6The schematic diagrams of the partial structure of the embodiment 3 are respectively the front view and the top view. The embodiment 3 is a specific implementation method of using a groove that can rotate around a fulcrum in a lever-like manner in combination with a press-and-spray device to extinguish cigarette butts in the groove. The cigarette extinguishing groove 40 formed by removing half of the side wall of the cylindrical tube is connected with two shaft sleeve mechanisms 42, one of which is close to the lower end of the groove and is fixedly connected to the track plate 44 through a bracket 51, and is used as a fulcrum for the rotation of the groove, and the other is close to the middle of the groove and is connected to the shaft sleeve mechanism 42 embedded in the strip hole 45 on the track plate 44 through a connecting rod 43, and is used to transmit the pressure water power. The shaft sleeve mechanism 42 is composed of a coaxial shaft and a sleeve or two coaxial hollow sleeve rings. The shaft and the sleeve or the sleeve and the sleeve can rotate relative to each other in the circumferential direction, but are restricted from relative displacement in the axial direction. The shaft and the sleeve, or the two hollow sleeve rings, can be connected by a bearing so that the relative rotation is rolling friction, or they can be directly connected so that the relative rotation is sliding friction. The upper end of the cigarette extinguishing groove 40 is connected to the flat cut of the lower end of the cigarette butt receiving tube 41. The cigarette butt receiving tube 41 is a column tube with an oblique cut at the upper end to facilitate the placement of cigarette butts. The lower end of the cigarette extinguishing groove 40 is opposite to the small opening at the upper end of the platform-shaped mouth cover 37, or directly extends into the small opening, and the lower end is fixedly connected with a nozzle 25, which can spray water columns or discrete water drops. During the rotation of the cigarette extinguishing groove 40 around the fulcrum, the water spraying direction of the nozzle 25 is fixed relative to the cigarette extinguishing groove 40, always facing the upper end of the groove and parallel to the groove. The platform-shaped mouth cover 37 is connected to the track plate 44 through a bracket 51, and is also movably connected to the cigarette butt storage bottle 50 through the internal threaded mouth cover 48 at the lower end. By screwing the storage bottle, it can be easily removed from the internal threaded mouth cover 48 for cleaning and reinstalled. The nozzle 25 is connected to the piston chamber of the push-type liquid spray pump core 2 through the water supply pipe 9, from which pressurized water can be obtained, and water can also be returned during the piston reset process to at least clear the unsprayed resident water in the last section of the water supply pipe 9 near the nozzle 25. The water supply pipe 9 passes through the shaft sleeve mechanism 42 as a fulcrum to prevent the water supply pipe 9 from expanding or shaking when the smoke extinguishing groove 40 rotates around the fulcrum. The water supply pipe 9 also passes through the ring inside of the internal threaded cover 48 connected to the upper end of the water storage bottle 49, and is carried on the side wall of the platform-shaped cover 37 connected to the upper end of the internal threaded cover 48, so as to ensure that the water storage bottle 49 can be completely separated from the internal threaded cover 48 to which it is movably connected by screwing it and can be freely loaded and unloaded. The unloaded water storage bottle 49 can be installed again after adding water and / or cleaning. The platform-shaped cover 37 above the water storage bottle 49 is connected to the track plate 44 through a bracket 51. The upper end of the platform-shaped cover 37 accommodates and supports the upper end of the push-type spray pump core 2 and closes the upper end of the small opening. The suction pipe 13 connected to the lower part and the lower end of the push-type spray pump core 2 extends into the inner cavity of the water storage bottle 49 to absorb water from it.The water pressure piston inside the press-type liquid spray pump core 2 is connected to the liquid spray pressing plate 8 through the liquid spray pressing rod 7. The piston is connected with a return spring, which can push the piston to return after the water spray pressure disappears. The return spring can be placed inside the press-type liquid spray pump core 2, or can be connected to the liquid spray pressing rod 7 or the liquid spray pressing plate 8. The liquid spray pressing plate 8 is connected to the pressing block 47, and the pressing block 47 is fixedly connected to the limit block 46 embedded in the strip hole 45, and is also connected to the shaft sleeve mechanism 42 embedded in the strip hole 45 through the pin 63. The limit block 46 can only move up and down in the strip hole 45, thereby driving and limiting the pressing block 47 to only move up and down. The smoke extinguishing groove 40 and the shaft sleeve mechanism 42 at the lower end thereof, in conjunction with the connecting rod 43 and the shaft sleeve mechanisms 42 at both ends thereof, as well as the track plate 44, the strip hole 45, the stopper 46, and the pressing block 47 together constitute a crankshaft transmission mechanism, which is used to convert the lever-like rotation of the smoke extinguishing groove 40 around the fulcrum into the up-and-down linear motion of the pressing block 47, so as to extinguish the cigarette butt. When using the device of this embodiment to extinguish a cigarette, first place the burning end of the cigarette butt downward and insert the cigarette butt into the cigarette butt receiving tube 41, then press the cigarette butt with your fingers and press the edge of the smoke extinguishing groove 40. Figure 5 Rotate it clockwise as shown, and let go when it cannot be rotated any further, and the smoke extinguishing operation is completed. In short, put it on, press it once, and then let go, and the smoke extinguishing operation is completed. The smoke extinguishing process is as follows: during the process of the smoke extinguishing groove 40 being pressed and rotated, the aforementioned crankshaft transmission mechanism drives the pressure block 47 to move downward, causing the piston chamber inside the press-type spray pump core 2 to supply pressurized smoke extinguishing water to the water supply pipe 9 and spray it through the nozzle 25 in the form of a water column or discrete water droplets to the burning end of the cigarette butt placed in the cigarette butt receiving tube 41. If the pressure, speed and quantity of the water sprayed by the nozzle 25 are sufficient, it can be directly poured on the burning end of the cigarette butt. If it is not sufficient, it is only necessary to continue to press the smoke extinguishing groove 40 to rotate until the pressing end of the cigarette butt receiving tube 41 is lower than the other end of the smoke extinguishing groove 40 connected to the nozzle 25. In this way, the pressed water can flow along the smoke extinguishing groove 40 under the action of gravity to meet the burning end of the cigarette butt and pour it on it, thereby realizing the meeting of water and fire and extinguishing the cigarette butt. After letting go, the reset spring pushes the pressure block 47 to move upward, and then drives the smoke extinguishing groove 40 along the aforementioned crankshaft transmission mechanism. Figure 5As shown, it rotates counterclockwise and returns to its original position. This process is driven by a return spring, so the speed is relatively fast, which will produce a counterclockwise throwing effect on the cigarette butts in the cigarette butt receiving tube 41, but the tubular form of the cigarette butt receiving tube 41 can ensure that the cigarette butts are not thrown out. When the cigarette extinguishing groove 40 returns to its initial vertical position or is close to vertical, the extinguished cigarette butts in the cigarette butt receiving tube 41 can fall freely under the action of gravity or slide downward along the groove wall of the cigarette extinguishing groove 40 into the inner cavity of the cigarette butt storage bottle 50. In this embodiment, the cigarette extinguishing groove 40 constitutes a labor-saving lever, which makes it easy to press down; the cigarette butt storage bottle 50 and the water storage bottle 49 can be detached by twisting, making it very easy to clean cigarette butts and add water; the track plate 44 is the supporting center of the entire device and must be fixed and stable; the length of the cigarette butt receiving tube 41 should be such that the burning end of the cigarette butt can be exposed when pressed, usually controlled within 15mm, so as to visually observe the extinguishing of the cigarette butt in the open side wall of the cigarette extinguishing groove 40. The water output of the push-type spray pump core 2 each time it is pressed needs to be reasonably controlled to ensure that the cigarette butt can be effectively extinguished and water can be saved to the maximum extent; each time it is pressed, it must be ensured that the cigarette extinguishing groove 40 can be rotated to the right position or exceed the minimum rotation angle limit. The present embodiment has the outstanding advantages of simple and reliable structure, easy and quick use, low maintenance cost, etc., and is widely applicable to single smoke extinguishing piles in municipal open-air public places or as smoke extinguishing components of garbage bins (tubes), and is also suitable for smoke extinguishing devices in various indoor and outdoor public places such as subway station entrances, bus stops, restaurants, hotels, and smoking rooms in stations (airports / piers), and can also be used in private places such as homes and cars.

[0044] Figure 7 is a schematic diagram of a partial structure of Example 4. Figure 8 yes Figure 7 A schematic diagram of the partial structure of the water retention groove 52 in the top view. Example 4 is a specific implementation method of using the cigarette butt wet extinguishing device as a component of the municipal garbage bin, realizing water supply through a foot-operated water pressure device, and using the surface tension of the water to form hanging water droplets on the convex mouth structure to "dip and extinguish" the cigarette butts. A cigarette butt and harmful substance recovery box 62 is provided between the garbage storage boxes 60 on the left and right sides. It is higher than the edge of the garbage storage boxes 60 on both sides, and supports the garbage bin top cover 59 that covers the entire garbage bin and plays a role in rain protection. A cigarette butt disposal entrance 61 is provided on the upper part of the cigarette butt and harmful substance recovery box 62, and a pedal hole 58 is provided on the bottom. The upper part of the cigarette butt disposal entrance 61 is provided with a downwardly protruding water retention groove 52 that is high on both sides and low in the middle to form a water retention convex mouth, and a water leakage port 53 is provided at the lowest point of the lower convex arc bottom, so that the water can flow in. Figure 8 The extinguishing water between the upper and lower leakage groove side walls 54 leaks out from the water retention groove 52 to the outside of the groove bottom under the action of gravity, and forms hanging water drops at the lowest point of the lower convex arc bottom of the water retention groove 52 by using the liquid surface tension, which is used to "extinguish" the cigarette butts. The extinguishing water comes from Figure 7The water outlet 10 shown is located at the high point on the right side of the water retention groove 52. A pedal 57 is arranged in the pedal hole 58, which is inclined from high to low along the direction from the inside to the outside, and the lowest point is at the bottom of the mouth edge of the pedal hole 58. The high end of the inclined pedal 57 is connected to the pull rope 55, the pressure block 47, and the return spring 56 in sequence upward and finally connected to the garbage bin top cover 59. A water tank 32 is arranged in the inner cavity of the cigarette butt and harmful substance recovery box 62, and a filling port 33 is arranged at the upper part, a sewage outlet 35 is arranged at the lower part, and a light-transmitting water level observation window 34 is arranged in the middle part. The filling port 33 can be communicated with the top surface of the garbage bin top cover 59 at the same time to collect rainwater for use as cigarette extinguishing water. The sewage outlet 35 is communicated with the outside of the garbage bin through a valve. The water level observation window 34 can be directly seen from the outside of the garbage bin to prompt timely addition of water or cleaning of sediment at the bottom of the water tank 32. A press-type liquid spray pump core 2 is arranged inside the water tank 32, and includes a piston chamber inside. The piston chamber absorbs water from the water tank 32 through the suction tube 13, and discharges the extinguishing water to the water outlet 10 through the water supply pipe 9. The piston of the press-type liquid spray pump core 2 is connected to the pressing block 47 through the liquid spray pressing rod 7 and the liquid spray pressing plate 8 in turn, so that it can move up and down with the pressing block 47. A cigarette butt storage bell mouth 28 and a cigarette butt storage cylinder 36 are arranged inside the cigarette butt and harmful substance recovery box 62 vertically below the cigarette butt discarding entrance 61 in turn. The bell mouth is used to guide the falling direction of the cigarette butt to ensure that it can fall into the storage cylinder. The box door behind the trash can is opened, and the storage cylinder can be taken out to clean and transport the cigarette butts. When using the present embodiment, a user who approaches the trash can and wishes to discard a cigarette butt first extends his foot to step on the foot pedal 57, which will drive the pull rope 55 to pull the pressure block 47 downward, and the pressure block 47 will push the piston to press out the cigarette extinguishing water from the push-type spray pump core 2, and the water will flow into the water retention groove 52 through the water supply pipe 9 and the water outlet 10. The cigarette extinguishing water will quickly gather at the bottom of the groove and leak out from the water leakage port 53 to form hanging water drops. The user can dip the burning end of the cigarette butt into the water droplets to extinguish it, and then throw the cigarette butt into the cigarette butt disposal inlet 61. Under the action of gravity, the cigarette butt will be collected by the cigarette butt storage. The bell mouth 28 falls into the cigarette butt storage tube 36. After extinguishing the cigarette and discarding it into the bucket, the user can leave. The pedal 57 will return to its original position under the pulling action of the return spring 56 and the pull rope 55, and the pressure block 47 will also be reset, thereby pushing the piston to absorb water from the water tank 32 through the suction tube 13, and also sucking back the water that has not been given out in the water supply pipe 9, so that the water supply pipe section near the water outlet 10 can be emptied to avoid freezing and blocking the next water outlet. The piston cavity that has absorbed water is ready for the next water pressure to extinguish the cigarette. At this point, a complete cigarette extinguishing process is completed.In this embodiment, the cigarette butt wet extinguishing device is applied to municipal garbage bins, and most garbage bins are located in open-air places such as roads, parks, and squares. The impact of the changing seasons on use needs to be considered. In cold weather, water is used to extinguish cigarettes, and since the amount of water given out in each burst is very small, a thinner water supply pipe needs to be used. Antifreeze becomes an important issue that cannot be ignored. Regardless of whether the water tank or the water pipe is frozen, the cigarette butt extinguishing water cannot be given out, causing the cigarette extinguishing device to fail. Antifreeze agent can be added to the cigarette butt extinguishing water, or the water tank and the water supply pipe can be wrapped with insulation material, warming measures can be taken, or a return water device can be set up so that after each cigarette butt water is given out, the remaining cigarette butt extinguishing water that has not been given out in the water supply passage can return to the water tank, thereby clearing the water supply passage to prevent freezing and blocking the next water discharge. This embodiment adopts the method of foot-operated water supply, which can avoid users from directly touching the public smoke extinguishing equipment with their hands, and can prevent cross infection; a drop of smoke extinguishing water is suspended at the cigarette butt disposal entrance of the trash can. Compared with the dry smoke extinguishing method with a pressed smoke extinguishing mesh, it can effectively avoid the safety hazard and environmental pollution of cigarette extinguishing sparks flying in the wind, and is a simpler, safer and more environmentally friendly way of extinguishing smoke.

[0045] Fig. 9 and Fig.10The schematic diagrams of the partial structure of the embodiment 5 are respectively the front view and the top view. The embodiment 5 is a simple wet cigarette butt extinguishing device used with a common cylindrical ashtray or attached to such an ashtray, which is used to improve the extinguishing efficiency and convenience of the common ashtray. A notch is left on the side of the water bottle support frame 68, so that the side periphery of the ashtray 69 can be inserted and the bottom of the ashtray can be pressed on the bottom of the water bottle support frame 68. When cleaning is needed, the ashtray 69 can be taken out, and the cigarette butts and ashes stored therein can be dumped and cleaned. The water bottle support frame 68 can also be fixedly set on the side periphery of the ashtray 69, so that the two become an integrated structure. The advantage is that it is easy to move, and there is no need to carry two objects every time moving, and the two must be separated before moving, and placed together after moving and the relative positions of the two must be adjusted. The disadvantage is that there are obstacles at the mouth of the ashtray when cleaning, which will cause some inconvenience. The frame surface of the water bottle support frame 68 is a platform for placing and supporting the water bottle 64. A water-retaining platform 67 is fixedly connected to the edge of the frame surface suspended above the ashtray 69. The water-retaining platform 67 can also be fixedly connected to the bottom of the water bottle 64. A water bottle sealing cover 65 is provided on the top of the water bottle 64, and a water bottle leaking port 66 is provided on the side wall of the water bottle 64 near the bottom of the bottle, which is adjacent to and faces the water-retaining platform 67.The principle of supplying water from the sealed water bottle 64 whose water level is higher than the water bottle leaking port 66 to the water station platform 67 is that the water column in the bottle, under the action of gravity, together with the air pressure in the sealed space between the water surface and the water bottle sealing cover 65, jointly creates a leakage pressure on the water bottle leaking port 66. The leakage pressure is greater than the external atmospheric pressure on the water film blocking the water bottle leaking port 66. Therefore, the water in the bottle will flow out from the inner cavity of the water bottle 64 through the water bottle leaking port 66 to the water station platform 67. When a small amount of water flows out, A low-pressure space equal to the amount of water flowing out will appear in the bottle, so that the pressure on the water film blocking the water leak 66 of the water bottle caused by the water column and air pressure in the bottle is reduced. Due to the surface tension of the water, the outflowing water will not be completely attached to the water-retaining platform 67, but will present a slope from high to low in the direction from the water leak 66 of the water bottle to the edge of the water-retaining platform 67. The external atmospheric pressure remains unchanged, and the pressure of the outflowing water and the external atmospheric pressure on the water film is almost maintained at When the internal and external pressures are equal, the water in the bottle can no longer flow out and will remain static. Only when the integrity of the water film blocking the leaking hole 66 of the water bottle is destroyed by the cigarette butt or other external forces, the external atmospheric pressure on the leaking hole 66 of the water bottle will instantly be greater than the internal pressure of the bottle, which will cause a small amount of external air to squeeze into the bottle through the leaking hole 66 of the water bottle, forming bubbles floating in the water column in the bottle, and finally merging into the dense air on the water surface. In the closed space gas, the internal pressure of the water bottle leaking port 66 is slightly increased, so that the water near the port can flow to the port to make up for the defect of the water film blocking the port. In this dynamic process of "air inlet and water outlet", a small amount of water will flow out from the water bottle leaking port 66 to the water station platform 67. The outflowing water will gradually repair the integrity of the water film blocking the water bottle leaking port 66, and will form a balance of pressure inside and outside the water film again, and finally, the water outflow will stop. It can be seen that with the help of atmospheric pressure and gravity, the water supply device composed of the closed water bottle 64, the water bottle leaking port 66 and the water station platform 67 can continuously and effectively provide trace water for cigarette butts to extinguish cigarettes by dipping and sucking, which is an ideal water supply solution for cigarette butts to extinguish cigarettes by dipping and sucking. The water-retaining platform 67 is a smooth plane of a circle, an ellipse or other regular shape, or a convex surface with a slight upward convexity, or a spoon-shaped pit or an open groove, which is suspended above the ashtray 69. As long as the cigarette butt to be extinguished is scratched on the water-retaining platform 67, the cigarette butt can be discarded, and the cigarette butt together with the excess extinguishing water on the water-retaining platform 67 and the mixture of cigarette ash and water will fall into the ashtray under the action of gravity, so that the water-retaining platform 67 can be kept clean and tidy at any time, which is convenient for maintenance. The water-retaining platform 67 can also be omitted, and the upper frame surface of the water bottle support frame 68 can be directly used as the water-retaining platform, which can also be used normally, but the use experience will be slightly worse.Compared with the common method of pre-placing some water at the bottom of the ashtray, this embodiment has the significant advantages of saving water, being easy to use, and easy to clean the ashtray. It is a construction scheme of a smoke extinguisher with simple structure, low cost, significant benefits, and strong practicality. The water supply device scheme of this embodiment can also be used in the above-mentioned embodiment 4.
