Description

Technical Field

[0001] The present invention is a vector leafless airflow smoke purifier, specifically a filter-type equipment with air purification function. This product detects smoke through a smoke sensor, then starts a brushless motor to drive a fan to suck the smoke into the channel, absorbs harmful gases through the filter, and then discharges the filtered gas into the air. Its core lies in the use of automated detection and active filtering technology to solve the technical defects of traditional ashtrays that can only collect ashes but cannot process secondhand smoke, thereby achieving active improvement of indoor air quality. After a period of use, the filter paper can be replaced by yourself to achieve the effect of purification and filtration. It can greatly improve the air quality and the health of the user. It is very different from the single function of ashtrays currently on the market. It changes the single function of ashtrays and improves the comprehensiveness of ashtrays. Background Art

[0002] Traditionally, ashtrays serve simply as containers for cigarette ash. Smoking produces a large amount of smoke, which degrades the surrounding environment and creates a strong odor that is difficult to remove. Many non-smokers experience discomfort and inhale large amounts of secondhand smoke from others smoking, which harms their health. Secondhand smoke also lingers on furniture, clothing, and other items, leaving a lingering odor. Smoke from smoking permeates the surrounding environment, rapidly degrading indoor air quality and causing significant distress to non-smokers. With increasing public awareness of the quality of our living environment, the limitations of traditional ashtrays have become increasingly apparent, creating an urgent need for a new product that effectively addresses smoke pollution. When smoke is detected, a fan automatically activates to draw in and filter the smoke, significantly reducing the odor of cigarettes and minimizing the harmful effects of secondhand smoke.

[0003] In addition, the existing related products with fan blades have fan blade structures that lead to uneven air flow, affecting the efficiency and stability of smoke inhalation, making it difficult to achieve efficient capture and purification of smoke. The fan-free design of the present invention can avoid the disadvantages brought by the above-mentioned fan blades, and at the same time, combined with the purification function, it can handle smoke more efficiently, safely and quietly, which is exactly what the current market lacks. Therefore, the market urgently needs a new ashtray with a fan-free design that can actively detect and quickly inhale and filter smoke when it is generated, effectively reducing the odor of cigarettes and the harm of secondhand smoke, so as to solve the shortcomings of traditional products in health protection and environmental purification. Summary of the Invention

[0004] (1) Technical problems to be solved

[0005] The purpose of the present invention is to provide a filterable air purification device to solve many problems existing in the prior art.

[0006] First of all, in order to address the defect that traditional ashtrays can only hold ashes but cannot process the smoke produced by smoking, which causes secondhand smoke to harm the health of people around and pollute the indoor environment, the present invention aims to achieve active detection and efficient purification of smoke by integrating smoke detection, a brushless motor-driven fanless airflow drive component and a filtering structure, thereby reducing the spread of secondhand smoke from the source, reducing its health threat to non-smokers, and improving indoor air quality.

[0007] Secondly, in response to the problems of some existing smoking control products with fan blades such as loud noise, easy dust accumulation and difficulty in cleaning, safety hazards and unstable airflow driving efficiency, the present invention reduces operating noise while ensuring effective inhalation of smoke, thereby improving the safety, convenience and comfort of product use.

[0008] In addition, the present invention also aims to provide a filterable ashtray with a reasonable structure and easy operation. By setting replaceable filter paper, it ensures the stability of the filtering effect during long-term use, meets the user's demand for comprehensive functions and practicality of ashtrays in various scenarios such as home, office, and catering, and fills the gap in the market for a new type of ashtray that has active smoke treatment, fan-free safety design and convenient maintenance.

[0009] (2) Technical solution

[0010] Structural Design: This invention primarily consists of core components, including a cylinder body, cylinder head, brushless DC motor, uniquely designed fan blades, a specially constructed smoke inlet, a high-efficiency filter, a conveniently removable filter cover, an integrated intelligent circuit, a rechargeable battery, and a highly sensitive smoke sensor. The cylinder body features a hollow interior, with a dedicated space between the top and bottom for the precise placement of the integrated circuit, battery, brushless DC motor, and fan blades, creating a highly efficient smoke inhalation and purification system.

[0011] Purification principle: A brushless DC motor drives a fan with a hollow center and special blades on the periphery to rotate at high speed, thereby generating a strong pressure differential. The smoke inlet, formed by the inner and outer walls of the cylinder, is uniquely designed to change direction every 30 degrees, achieving all-round and no-dead-angle capture of the surrounding smoke, and efficiently inhaling it into the ashtray. The inhaled smoke is then filtered through a high-precision filter, and the purified fresh air is finally discharged from the bottom of the cylinder. This bladeless design not only avoids the noise, dust accumulation and safety hazards caused by traditional fan blades, but also can stably generate negative pressure to ensure the efficiency of smoke inhalation.

[0012] Intelligent Control System: The integrated circuit integrates an LED indicator, a Type-C port, and a smoke sensor. The smoke sensor monitors the surrounding smoke concentration in real time. Once smoke is detected, it automatically triggers the circuit, activating the brushless DC motor and initiating a highly efficient air purification process. The LED indicator not only visually displays the battery charge status but also accurately calculates the filter lifecycle by recording the air purification time, prompting users to replace the filter promptly. The Type-C port provides a convenient and fast way to charge the battery.

[0013] (3) Beneficial effects

[0014] From a health perspective, this invention uses a smoke sensor to detect smoke in real time. Once smoke is detected, it rapidly activates a brushless motor and bladeless airflow drive assembly, actively drawing smoke into a filtration channel. After the smoke is filtered through the filter paper, harmful components such as nicotine and tar are effectively adsorbed. The filtered gas is then released into the air, significantly reducing the spread of secondhand smoke and the risk of non-smokers inhaling it. This provides strong protection for the respiratory and cardiovascular systems of those around them. It is particularly suitable for use in crowded or enclosed spaces such as homes and offices.

[0015] The bladeless airflow drive offers significant advantages in terms of user experience. Compared to traditional bladed systems, the bladeless design eliminates the noise generated by high-speed rotation, making the product run more quietly and without causing additional noise interference to the surrounding environment. Furthermore, the lack of blades eliminates the problem of dust accumulation and difficulty in cleaning, reducing maintenance hassles for users. Furthermore, the absence of blades eliminates the safety risks posed by blades, reducing the risk of accidents even when children are nearby, thus improving safety and comfort.

[0016] In terms of practicality and affordability, the product boasts a rational structural design, with components working together stably and reliably. The replaceable filter paper allows for timely replacement based on usage, ensuring consistent filtration effectiveness over the long term. The low cost of the filter paper effectively controls operating costs. Furthermore, the product's compact size makes it suitable for a variety of scenarios, including homes, offices, and restaurants. Unlike larger air purifiers, which require significant space and high purchase and operating costs, the product can precisely and quickly remove smoke from the ashtray, making it even more practical.
