Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment manufacturing technology in the tobacco industry, and in particular to a cleaning mechanism for a narrow detection channel and a cleaning device for tobacco detection and analysis equipment. Background Technology

[0002] Tobacco testing and analysis equipment is diverse and comprehensive in function. Among them, cigarette draw resistance testers, circumference measuring instruments, and hardness testers accurately measure the combustion resistance, diameter, and compressive strength of cigarettes through simulated smoking conditions, optical scanning, and pressure testing, respectively. These devices, with their advantages of high precision, automation, and standardization, are widely used throughout the entire tobacco production process, contributing to quality control and process optimization. In the quality control of tobacco products, the detection of core indicators such as cigarette draw resistance, circumference, and hardness relies on high-precision equipment. The detection channels of the aforementioned testers are mostly designed with a narrow, elongated cylindrical structure to ensure accurate sample positioning and reliable test data. During tobacco testing, impurities such as tobacco fragments, tar, and dust easily adhere to the inner wall of the narrow testing channel. If not cleaned in time, this can lead to a decrease in the channel's inner diameter and changes in airflow resistance, affecting the accuracy of suction resistance testing. Accumulated impurities can also interfere with the optical system's capture of the sample's contour, causing circumferential measurement deviations. Residual substances may alter the contact state between the sample and the channel, causing abnormal pressure transmission during hardness testing. Furthermore, long-term accumulation of impurities can easily breed microorganisms or produce odors, polluting the testing environment and affecting the equipment's lifespan and the reliability of the test results. Therefore, regular channel cleaning is crucial for maintaining testing accuracy and ensuring the normal operation of the equipment.

[0003] Currently, operators generally use methods such as air guns or ear bulbs to clean the narrow detection channels. However, the narrow detection channels have limited internal space, making it difficult for airflow to evenly cover the inner walls of the channels. This results in stubborn stains and fine debris being difficult to remove completely, leading to decreased detection accuracy and consequently poor accuracy and stability of the detection results.

[0004] Therefore, there is an urgent need for a cleaning mechanism for narrow detection channels that can solve the problem that existing cleaning mechanisms do not thoroughly clean narrow detection channels. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning mechanism for narrow detection channels, which can solve the problem that existing cleaning mechanisms do not thoroughly clean narrow detection channels, thereby avoiding the situation where dust and dirt residues affect the detection accuracy and lead to poor accuracy and stability of detection results.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows: A cleaning mechanism for a narrow detection channel, used to clean the narrow detection channel of a tobacco detection and analysis device, comprising: A dust cleaning unit, wherein the dust cleaning unit has a thin cylindrical structure and can be inserted into the detection channel, the dust cleaning unit includes a first cleaning body and a dust removal outer layer, the dust removal outer layer covers the outer peripheral surface of the first cleaning body and contacts the inner wall of the detection channel; A dirt cleaning unit is located downstream of and connected to the dust cleaning unit. The dirt cleaning unit can be inserted into the detection channel. The dirt cleaning unit has a thin cylindrical structure and includes a second cleaning body and a descaling outer layer. The descaling outer layer covers the outer peripheral surface of the second cleaning body and contacts the inner wall of the detection channel.

[0007] As an optional solution for the cleaning mechanism used in the narrow detection channel, the dust cleaning unit and the dirt cleaning unit are detachably connected.

[0008] As an alternative to the cleaning mechanism for the narrow detection channel, the dust cleaning unit is threadedly connected to the dirt cleaning unit.

[0009] As an alternative to the cleaning mechanism for the narrow detection channel, the outer diameter of the dust cleaning unit is the same as the inner diameter of the detection channel.

[0010] As an optional solution for the cleaning mechanism used in the narrow detection channel, the dust removal outer layer is a fine velvet outer layer, which includes a velvet surface and a first connecting surface. The first connecting surface covers the outer periphery of the first cleaning body and is connected to the first cleaning body. The velvet surface is used to contact the inner wall of the detection channel, and the velvet surface can remove dust from the inner wall of the detection channel and the detection mechanism embedded in the inner wall of the detection channel.

[0011] As an alternative to the cleaning mechanism for the narrow detection channel, the first cleaning body is made of plastic material.

[0012] As an alternative to the cleaning mechanism for the narrow detection channel, the outer diameter of the dirt cleaning unit is the same as the inner diameter of the detection channel.

[0013] As an optional solution for the cleaning mechanism used in the narrow detection channel, the descaling outer layer is a bristle outer layer, which includes a second connecting surface and a bristle surface. The second connecting surface covers the outer periphery of the second cleaning body and is connected to the second cleaning body. The bristle surface is used to contact the inner wall of the detection channel, and the bristle surface can remove dirt from the inner wall of the detection channel and the detection mechanism embedded in the inner wall of the detection channel.

[0014] As an alternative to the cleaning mechanism for the narrow detection channel, the second cleaning body is made of plastic material.

[0015] A cleaning device for a tobacco detection and analysis apparatus includes a cleaning device body and a cleaning mechanism for a narrow detection channel, wherein the cleaning mechanism for the narrow detection channel is disposed on the cleaning device body.

[0016] The beneficial effects of this utility model are as follows: This invention proposes a cleaning mechanism for a narrow detection channel. The dust cleaning unit has a thin cylindrical structure and can be inserted into the detection channel. The dust cleaning unit includes a first cleaning body and a dust-removing outer layer. The dust-removing outer layer covers the outer circumference of the first cleaning body and contacts the inner wall of the detection channel. A dirt cleaning unit is located downstream of the dust cleaning unit and connected to it. The dirt cleaning unit can be inserted into the detection channel. The dirt cleaning unit has a thin cylindrical structure and includes a second cleaning body and a descaling outer layer. The descaling outer layer covers the second cleaning body. The outer circumference of the main body, with its descaling outer layer in contact with the inner wall of the detection channel, features a slender cylindrical structure for both dust and dirt cleaning units. This allows for easy insertion into the narrow detection channel, achieving effective cleaning of its interior. Compared to gentle blowing with an air gun or ear suction bulb, this method penetrates deeper and more precisely into the narrow detection channel.

Compared to simply using an air gun or ear-blower to blow, it can not only clean dust but also solve dirt problems, making it more comprehensive and avoiding the impact of dirt residue on the equipment's detection accuracy.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] This embodiment provides a cleaning mechanism for a narrow detection channel, which is used to clean the narrow detection channel of a tobacco detection and analysis device, such as... Figures 1-2 As shown, in this embodiment, the cleaning mechanism for the narrow detection channel includes a dust cleaning unit 1 and a dirt cleaning unit 2. The dust cleaning unit 1 has a thin cylindrical structure and can be inserted into the detection channel. The dust cleaning unit 1 includes a first cleaning body and a dust removal outer layer. The dust removal outer layer covers the outer circumference of the first cleaning body and contacts the inner wall of the detection channel. The dirt cleaning unit 2 is located downstream of the dust cleaning unit 1 and connected to it. The dirt cleaning unit 2 can be inserted into the detection channel. The dirt cleaning unit 2 has a thin cylindrical structure and includes a second cleaning body 21 and a descaling outer layer 22. The descaling outer layer 22 covers the outer periphery of the second cleaning body 21. The descaling outer layer 22 contacts the inner wall of the detection channel. The dust cleaning unit 1 and the dirt cleaning unit 2 are designed as thin cylindrical structures, which can be smoothly inserted into the narrow detection channel to achieve effective cleaning of the inside of the channel. Compared with the gentle blowing of the air gun and the gentle blowing of the ear bulb, it can be inserted deeper and more accurately into the narrow detection channel. Physical cleaning is achieved through the direct contact between the outer layer and the inner wall of the channel, avoiding the dead corner problem of the airflow cleaning method. The dust and dirt inside the detection channel are removed more thoroughly, and the dust and dirt residue is prevented from affecting the detection accuracy and causing poor accuracy and stability of the detection results. The dust removal outer layer of the dust cleaning unit 1 can contact the inner wall of the detection channel under the action of the first cleaning body, effectively cleaning the dust in the channel; the dirt cleaning unit 2 can clean dirt by contacting the inner wall of the channel through the descaling outer layer 22. Compared with a single air gun or ear blower, it can not only clean dust, but also solve the problem of dirt, which is more comprehensive and can avoid the impact of dirt residue on the detection accuracy of the equipment; the operator can also choose to hold one end of the cleaning mechanism for the narrow detection channel and insert the other end into the detection unit to carry out cleaning work according to different cleaning needs.

[0026] Preferably, such as Figures 1-2As shown in this embodiment, the dust cleaning unit 1 and the dirt cleaning unit 2 are detachably connected, enabling independent disassembly and replacement of the two. When the outer layer of one of the units is worn or needs to be adjusted for different cleaning needs, the dust cleaning unit 1 or the dirt cleaning unit 2 can be disassembled and replaced separately without replacing the entire cleaning mechanism. This improves the flexibility of the cleaning unit, facilitates maintenance, and reduces maintenance costs. At the same time, it allows for flexible combination or individual use of a cleaning unit based on the actual contamination of dust or dirt in the detection channel, improving the targeting and efficiency of the cleaning operation.

[0027] Optionally, such as Figures 1-2 As shown, in this embodiment, the dust cleaning unit 1 and the dirt cleaning unit 2 are threadedly connected. The dirt cleaning unit 2 extends a threaded post 23 along its extension direction, and the threaded post 23 is threadedly connected to the dust cleaning unit 1, achieving a stable and convenient assembly and disassembly. The thread engagement ensures the tightness and reliability of the connection between the two cleaning units, preventing loosening during the cleaning process and ensuring stable cleaning operations. During disassembly, only one of the dust cleaning unit 1 and the dirt cleaning unit 2 needs to be rotated to separate them, facilitating quick replacement of the worn outer layer or individual repair of a specific cleaning unit, reducing maintenance difficulty and time costs. In other embodiments, the threaded post 23 may also extend from the dust cleaning unit 1 and be threadedly connected to the dirt cleaning unit 2. In some other embodiments, the dust cleaning unit 1 and the dirt cleaning unit 2 are magnetically connected. First magnetic components capable of magnetic connection are respectively provided at the connection point of the dust cleaning unit and the dirt cleaning unit. The magnetic connection of the two first magnetic components ensures that the dust cleaning unit 1 and the dirt cleaning unit 2 are firmly connected, working together to clean the dust and dirt in the detection channel. The magnetic connection of the dust cleaning unit 1 and the dirt cleaning unit 2 also allows for quick and convenient assembly and separation without the need for complex tools, greatly improving maintenance efficiency. The magnetic connection also ensures precise alignment, avoiding the impact of installation errors on the cleaning effect. In other embodiments, the dust cleaning unit 1 and the dirt cleaning unit 2 can also be connected by quick-release pins or quick connectors.

[0028] Optionally, in this embodiment, the outer diameter of the dust cleaning unit 1 is the same as the inner diameter of the detection channel, which allows the outer peripheral surface of the dust cleaning unit 1 to fit tightly against the inner wall of the detection channel. After being inserted into the channel, it forms a gapless contact state. The dust removal outer layer can fully cover every surface of the inner wall of the channel. Driven by the first cleaning body, the dust is thoroughly removed through physical contact, avoiding dust residue or cleaning dead corners due to gaps. This ensures that no dust is missed during the cleaning process, thereby effectively improving the thoroughness and accuracy of cleaning, ensuring the cleanliness of the inside of the detection channel, preventing dust residue from affecting the detection accuracy of the tobacco detection and analysis equipment, and ensuring the accuracy and stability of the detection results. In other embodiments, the outer diameter of the dust cleaning unit 1 can be slightly smaller than the inner diameter of the detection channel, which allows the dust cleaning unit 1 to be inserted more smoothly into the narrow detection channel, reducing frictional resistance and mechanical interference during insertion. This avoids the cleaning unit being unable to penetrate the channel smoothly or damaging the inner wall of the channel due to an excessively large outer diameter, ensuring the feasibility of the cleaning operation and the safety of the equipment. The slightly smaller outer diameter allows the dust removal outer layer to maintain appropriate contact pressure with the inner wall of the channel under the action of the first cleaning body. This ensures that the outer layer is fully attached to the inner wall to effectively remove dust, while avoiding increased movement resistance or damage to the outer layer due to excessive contact. This achieves more efficient and reliable cleaning of the dust inside the detection channel.

[0029] Specifically, in this embodiment, the dust removal outer layer is a fine down outer layer, which includes a down surface and a first connecting surface. The first connecting surface covers the outer periphery of the first cleaning body and is connected to the first cleaning body. The down surface is used to contact the inner wall of the detection channel. The down surface can remove dust from the inner wall of the detection channel and the detection mechanism embedded in the inner wall of the detection channel. The fine down outer layer can effectively adsorb and remove dust from various places in the channel. Whether it is surface dust or dust attached to tiny grooves and gaps, it can be removed.

[0030] Preferably, in this embodiment, the fine down outer layer is a fine down structure that is both dust-removing and soft. The soft down ensures that the detection channel and equipment will not be worn or scratched during the dust removal process, thus protecting the integrity of the equipment. At the same time, this soft down structure can reduce the frictional resistance during cleaning, making the dust cleaning unit 1 move more smoothly in the detection channel, improving cleaning efficiency, and avoiding the impact of dust residue on the detection accuracy of the tobacco detection and analysis equipment, thus ensuring the stable and accurate operation of the equipment.

[0031] Optionally, in this embodiment, the fine pile outer layer is velvet. In other embodiments, the fine pile outer layer may also be fleece or corduroy, etc.

[0032] Optionally, in this embodiment, the first cleaning body is made of plastic material. Plastic has good plasticity, allowing the first cleaning body to be molded into a shape that fits the detection channel, facilitating the insertion of the dust cleaning unit 1 into the detection channel. Simultaneously, thanks to the good plasticity and adaptability of the plastic material, it bonds tightly with the dust-removing outer layer, ensuring that the dust-removing outer layer maintains a stable shape when inserted into the narrow detection channel, thereby effectively contacting the inner wall of the channel to clean dust. In other embodiments, the first cleaning body may also be made of materials such as plastic or metal.

[0033] Preferably, in this embodiment, the outer diameter and length of the dust cleaning unit 1 are close to the outer diameter and length of a conventional cigarette, which makes the size of the dust cleaning unit 1 more compatible with the specifications of the narrow detection channel, thereby enabling the dust cleaning unit 1 to be smoothly inserted into the detection channel and extend deep into the channel, achieving comprehensive cleaning of the inside of the channel.

[0034] Optionally, in this embodiment, the outer diameter of the dirt cleaning unit 2 is the same as the inner diameter of the detection channel, which allows the dirt cleaning unit 2 to fit tightly against the inner wall of the detection channel. After being inserted into the detection channel, the descaling outer layer 22 can completely cover the inner wall of the channel, achieving thorough cleaning without dead angles through physical contact. This avoids dirt residue caused by gaps, ensures full contact between the descaling outer layer 22 and the inner wall of the channel, and makes the dirt cleaning more thorough. This effectively solves the problem of blind spots caused by the inability to make close contact in airflow cleaning methods, improves the dirt removal effect, and thus ensures the cleanliness of the detection channel. It also prevents dirt residue from affecting the detection accuracy of the tobacco detection and analysis equipment, and ensures the accuracy and stability of the detection results.

[0035] Specifically, such as Figures 1-2 As shown, in this embodiment, the descaling outer layer 22 is a bristle outer layer, which includes a second connecting surface and a bristle surface. The second connecting surface covers the outer periphery of the second cleaning body 21 and is connected to the second cleaning body 21. The bristle surface is used to contact the inner wall of the detection channel. The bristle surface can remove dirt from the inner wall of the detection channel and the detection mechanism embedded in the inner wall of the detection channel. The bristle outer layer can thoroughly and meticulously remove dirt attached to the inner wall of the channel and the detection mechanism embedded therein by means of the close contact between the bristle surface and the inner wall of the detection channel. Compared with the airflow cleaning method, it can penetrate into narrow spaces, effectively avoid cleaning dead corners, and accurately remove dirt. It makes up for the shortcomings of traditional cleaning tools such as air guns or ear suction bulbs, which can only clean dust. It has more comprehensive functions, can effectively ensure the cleanliness of the detection channel, reduce the impact of dirt residue on the detection accuracy of the equipment, and improve the accuracy and stability of the detection results.

[0036] Optionally, in this embodiment, the outer layer of the brush bristles is made of soft plastic bristles. These soft plastic bristles can penetrate deep into the gaps in the inner wall of the detection channel and conform to complex curved surfaces, efficiently scraping and cleaning dirt. This achieves precise cleaning of the dirt on the inner wall of the narrow detection channel of the tobacco detection and analysis equipment and on the detection mechanism embedded therein. The soft plastic bristles have good wear resistance and elasticity, ensuring effective cleaning of stubborn dirt without damaging the inner wall of the detection channel and the detection mechanism due to excessive hardness. The plastic material is corrosion-resistant, not easily deformed, and has a long service life, providing long-term stable cleaning. Compared to hard bristles, soft plastic bristles are more flexible and can adapt to narrow channels with hard-to-clean corners after being embedded in the detection mechanism. In other embodiments, the outer layer of the brush bristles can also be a rubber bristle structure or a sponge bristle structure, etc.

[0037] Optionally, in this embodiment, the second cleaning body 21 is made of plastic material. Plastic has good plasticity and can be processed into a thin cylindrical structure that fits the narrow detection channel. Plastic also has good chemical stability and is not prone to chemical reaction with substances it comes into contact with during the cleaning process, ensuring the structural stability and durability of the cleaning body, extending the service life of the cleaning mechanism, and preventing the cleaning effect and normal operation of the detection equipment from being affected by the material itself. In other embodiments, the second cleaning body 21 may also be made of materials such as plastic or metal.

[0038] Preferably, in this embodiment, the outer diameter and length of the dirt cleaning unit 2 are close to the outer diameter and length of a conventional cigarette. With similar dimensions, the cleaning blind spots or jamming of the cleaning unit caused by size differences can be reduced, thus reducing the difficulty of cleaning and the risk of damage to the inner wall of the detection channel. The dirt cleaning unit 2 can also easily simulate the passage path of a cigarette in a narrow detection channel, ensuring that it can smoothly penetrate into all parts of the channel for cleaning operations.

[0039] This embodiment also provides a cleaning device for a tobacco detection and analysis equipment. In this embodiment, the cleaning device for the tobacco detection and analysis equipment includes a cleaning device body and a cleaning mechanism for a narrow detection channel. The cleaning mechanism for the narrow detection channel is disposed on the cleaning device body. With the help of the narrow detection channel cleaning mechanism disposed on the cleaning device body and including a dust cleaning unit 1 and a dirt cleaning unit 2, the inside of the narrow detection channel can be physically cleaned thoroughly and accurately, effectively removing dust and dirt, avoiding the dead corner problem of airflow cleaning method and the influence of residue on detection accuracy, and ensuring the accuracy and stability of detection results.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
