A cigarette extinguishing column capable of automatically extinguishing residual fire

Abstract

This application relates to the field of cigarette extinguishing column technology and discloses a cigarette extinguishing column that can automatically extinguish residual flames. It includes a column with a cavity, an ash collection assembly at the top of the column, an ash collection assembly including an ashtray mounted on the column, and several cigarette butt collection assemblies located outside the ashtray inside the column. Each cigarette butt collection assembly includes a collection channel inside the column, a baffle at the end of the collection channel, and a rotating flip cover at the upper end of the collection channel. This application allows the smoker to press down on the cigarette butt to push the rotating flip cover to flip, and the friction and pressure generated by the collision rapidly lowers the temperature or even extinguishes the flame. If the cigarette butt slides into the inclined tube and still has residual flame, the rotating flip cover and the baffle isolate the smoker from external air and reduce air contact, quickly extinguishing the flame. After the cigarette butt slides down, it collides a second time with the baffle under gravity, ensuring complete extinguishment. This method is simple to operate and highly safe.

Description

Technical Field

[0001] This application relates to the field of smoke extinguishing column technology, and in particular to a smoke extinguishing column that can automatically extinguish residual fire. Background Technology

[0002] Currently, smoking is widespread and frequent in urban public places such as streets, parks, and squares, and the indiscriminate disposal of cigarette butts has become a major problem for urban environmental management. While traditional trash cans provide a place for citizens to dispose of garbage, they are clearly inadequate for special waste such as cigarette butts. Cigarette butts are small, hot, and often contain unextinguished embers, posing a fire hazard, and are also inconvenient for waste sorting and disposal.

[0003] To address this issue, some regions have experimented with installing simple cigarette butt collection containers. While these containers have guided the centralized disposal of cigarette butts to some extent, they lack built-in fire extinguishing mechanisms, still requiring smokers to extinguish their cigarette butts themselves before disposal. In practice, their implementation is not very effective, and they cannot fundamentally solve the fire risks and environmental pollution problems that cigarette butts may cause. Utility Model Content

[0004] To address the safety hazard posed by the inability of existing cigarette butt collection structures to effectively ensure that cigarette butts are extinguished quickly and completely after disposal, this application provides a cigarette butt extinguishing column that can automatically extinguish residual flames.

[0005] The smoke extinguishing column that can automatically extinguish residual fire provided in this application adopts the following technical solution:

[0006] A smoke extinguishing column capable of automatically extinguishing residual fire includes a column with a cavity. An ash collection assembly is located at the top of the column. The ash collection assembly includes an ashtray mounted on the column. Several cigarette butt collection assemblies are located outside the ashtray inside the column. Each cigarette butt collection assembly includes a collection channel within the column. A baffle is located at the end of the collection channel, and a rotating flip-top is located at the top of the collection channel to isolate air from the collection channel, thereby achieving automatic fire extinguishing.

[0007] Preferably, the column includes a housing for fixing to the ground, and a collection bucket is provided on the inner side of the housing and located below the collection channel.

[0008] Preferably, the side of the collection bucket on the shell is provided with a door, and a sealing structure is provided at the connection between the door and the shell.

[0009] Preferably, the upper end of the ashtray is provided with a detachable perforated mesh plate to prevent larger debris from entering the ashtray.

[0010] Preferably, a rain cover is provided on the top of the housing.

[0011] Preferably, the collection channel includes a guide hopper fixedly disposed on the inner side wall of the housing, and the lower end of the guide hopper is provided with an inclined tube.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By using the ash collection component, cigarette butt collection component, and collection bin in combination, when discarding a cigarette butt, the smoker holds the cigarette butt down and pushes the rotating flip cover to flip it over. The friction and pressure generated by the collision of the cigarette butts can quickly reduce the temperature of the cigarette butts and extinguish them. If the cigarette butt slides into the inclined tube and still has a residual flame, the rotating flip cover and the baffle isolate it from the outside air, reducing the contact area with the air and thus extinguishing it quickly. After the cigarette butt slides down, under the action of gravitational potential energy, it will collide with the baffle a second time, which can ensure complete extinguishing. The baffle and the rotating flip cover can automatically return to the closed state under the action of gravity to prevent odor and ash from spilling out. Compared with existing technologies, it has the advantages of simple operation and high safety. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a smoke extinguishing column capable of automatically extinguishing residual fires. (Refer to...) Figure 1-3 A smoke extinguishing column capable of automatically extinguishing residual fires includes a column 1 installed on the ground. The column 1 includes a shell 101 with an internal cavity. A collection bucket 4 is installed inside the cavity. The side of the collection bucket 4 on the shell 101 is connected to a door 102 via a hinge. A sealing structure, such as a gasket, is installed at the connection between the door 102 and the shell 101. A latch is installed on the shell 101 and the door 102 to lock the shell 101 and the door 102, ensuring an airtight connection.

[0020] Reference Figure 2 The upper end of the housing 101 is equipped with an ash collection assembly 2. The ash collection assembly 2 includes an ashtray 201 that is slidably snapped onto the top of the housing 101. A perforated mesh plate 202 is detachably installed on the ashtray 201. The perforated mesh plate 202 has a hole diameter of 0.8 to 1.5 cm to prevent larger debris from entering the ashtray 201.

[0021] Reference Figure 3 Several cigarette butt collection assemblies 3 are installed on the outer side of the ashtray 201 inside the column 1. Each cigarette butt collection assembly 3 includes a collection channel composed of a guide hopper 301 and an inclined tube 302. A baffle 303 is hinged to the inclined tube 302, and a rotating flip-top 304 is hinged to the upper end of the guide hopper 301. The entire cigarette butt collection assembly 3 is made of stainless steel, and a counterweight is installed on the bottom surface of the rotating flip-top 304. The diameter of the inclined tube 302 is slightly larger than the diameter of the cigarette butt, which reduces the contact area between the cigarette butt and the air after it enters the inclined tube 302, thus extinguishing it quickly. The inner wall of the inclined tube 302 is smooth, and the inclination angle is 70-80 degrees, allowing the cigarette butt to slide smoothly into the collection bin 4 at the bottom after it is extinguished.

[0022] Reference Figure 1 The top of the housing 101 is equipped with a rain cover 5 for wind and rain protection, protecting the internal components from severe weather.

[0023] The implementation principle of the smoke extinguishing column that can automatically extinguish residual fire in this application embodiment is as follows:

[0024] When a smoker wants to discard a cigarette butt, they first press down on the rotating flap 304 while holding the still-burning butt. The flap 304 rotates downwards around its hinge point with the guide hopper 301, opening the flap and allowing the butt to fall into the inclined tube 302. Under its own weight, the butt slides quickly down the inclined tube 302. During this descent, the narrow space of the inclined tube 302 reduces the contact area between the butt and the air, while heat dissipates rapidly, extinguishing any remaining embers quickly. The butt continues to slide down, passing through the baffle 303 (normally closed), which the butt can push open to enter, finally falling into the collection bin 4 located within the cavity of the column 1. When the cigarette butt passes the rotating flip cover 304, it is impacted, and the friction and pressure quickly reduce the temperature of the cigarette butt, causing it to extinguish. After the cigarette butt slides down, it collides a second time with the baffle 303 under the action of gravitational potential energy. Through the two collisions and the reduction of the cigarette butt's contact with air, it is ensured that the remaining fire of the cigarette butt can be completely extinguished during the falling process.

[0025] When it is necessary to clean the collection bucket 4, the latch can be opened and the door 102 can be opened using the hinge to remove the collection bucket 4 for cleaning.
