[0074] To make the above-mentioned objectives, features and beneficial effects of the embodiments of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0075] This application provides an ashtray 100, with reference to... Figures 1 to 9 The ashtray 100 includes: a housing 5, a cylinder 2 housed within the housing 5, a filter assembly 3, and a fan assembly 4. A first air inlet 21 is provided on the housing 5 and / or the cylinder 2. The cylinder 2 includes an annular sidewall 22 and a bottom 24, which together form an ash collection section 28. The ash collection section 28 can be used to collect cigarette ash or cigarette butts. The cylinder 2 being housed within the housing 5 can mean that the cylinder 2 is fitted onto the housing 5, or it can mean that it is connected to the top of the housing 5.

[0076] The filter assembly 3 is connected to the first air inlet 21 and is located downstream of the first air inlet 21. The fan assembly 4 causes air to enter from the first air inlet 21 and be filtered by the filter assembly 3 before being discharged. The connection between the filter assembly 3 and the first air inlet 21 means that they are fluidly connected or fluidly conductive, that is, after air enters from the first air inlet 21, it can flow to the filter assembly 3.

[0077] The first air inlet 21 can be configured in several ways. Some of these configurations are described below:

[0078] In some embodiments, see Figure 10 , Figures 13 to 16 The cylinder body 2 includes an upper edge 23 extending from the top 223 of the annular sidewall 22 toward a direction away from the ash collection part 28. A first air inlet 21 is continuously provided on the upper edge 23 and the annular sidewall 22. That is, the first air inlet 21 spans the upper edge 23 and the annular sidewall 22.

[0079] The upper edge 23 of the cylinder body can extend horizontally away from the ash collection part 28. The upper edge 23 of the cylinder body can also extend obliquely upward or downward away from the ash collection part 28.

[0080] There are multiple first air inlets 21, and at least a portion of the multiple air inlets 21 are continuously disposed on the upper edge 23 of the cylinder body and the annular sidewall 22. For example, all the first air inlets 21 are continuously disposed on the upper edge 23 of the cylinder body and the annular sidewall 22. Alternatively, a portion of the first air inlets 21 may be continuously disposed on the upper edge 23 of the cylinder body and the annular sidewall 22, while another portion of the first air inlets 21 may be disposed only on the upper edge 23 of the cylinder body or only on the upper part of the annular sidewall 22. Distributing the first air inlets 21 on the upper edge 23 of the cylinder body and the annular sidewall 22 increases the purification range of the ashtray 100 for the surrounding air, improves the collection and purification effect of the smoke in the air, and also facilitates the mold manufacturing of the cylinder body 2.

[0081] The length of the first air inlet 21 on the annular sidewall 22 is less than 100% of the height of the annular sidewall. Further, the length of the first air inlet 21 on the annular sidewall 22 is greater than or equal to 3% of the height of the annular sidewall and less than 100% of the height of the annular sidewall. Further, the length of the first air inlet 21 on the annular sidewall is greater than or equal to 3% of the height of the annular sidewall and less than or equal to 75% of the height of the annular sidewall. Further, the length of the first air inlet 21 on the annular sidewall is greater than or equal to 3% of the height of the annular sidewall and less than or equal to 50% of the height of the annular sidewall. Further, the length of the first air inlet 21 on the annular sidewall is greater than or equal to 15% of the height of the annular sidewall and less than or equal to 50% of the height of the annular sidewall. Further, the length of the first air inlet 21 on the annular sidewall is greater than or equal to 20% of the height of the annular sidewall and less than or equal to 50% of the height of the annular sidewall. For example, the length of the first air inlet 21 on the annular sidewall is equal to 25% of the height of the annular sidewall. In this way, while ensuring the air intake effect of the first air inlet 21, the smoke and ash are prevented from entering the ashtray 100 from the first air inlet 21.

[0082] In the direction away from the ash collection section 28 on the upper edge 23 of the cylinder body, the length of the first air inlet 21 on the upper edge 23 of the cylinder body is less than or equal to the width of the upper edge 23 of the cylinder body. Further, the length of the first air inlet 21 on the upper edge 23 of the cylinder body is greater than or equal to 5% and less than or equal to 100% of the width of the upper edge of the cylinder body. Further, the length of the first air inlet 21 on the upper edge 23 of the cylinder body is greater than or equal to 10% and less than or equal to 90% of the width of the upper edge of the cylinder body. Further, the length of the first air inlet 21 on the upper edge 23 of the cylinder body is greater than or equal to 25% and less than or equal to 80% of the width of the upper edge of the cylinder body. For example, the length of the first air inlet 21 on the upper edge 23 of the cylinder body is equal to 75% of the width of the upper edge of the cylinder body.

[0083] In some embodiments, the length of the first air inlet 21 on the upper edge 23 of the cylinder body is less than or equal to its length on the annular sidewall 22.

[0084] Furthermore, the ratio of the length of the first air inlet 21 on the upper edge 23 of the cylinder block to its length on the annular sidewall 22 is greater than or equal to 20% and less than or equal to 80%.

[0085] Furthermore, the ratio of the length of the first air inlet 21 on the upper edge 23 of the cylinder block to its length on the annular sidewall 22 is greater than or equal to 25% and less than or equal to 70%.

[0086] Furthermore, the ratio of the length of the first air inlet 21 on the upper edge 23 of the cylinder block to its length on the annular sidewall 22 is greater than or equal to 30% and less than or equal to 60%.

[0087] For example, the length of the first air inlet 21 on the upper edge 23 of the cylinder block is 30% of the length on the annular sidewall 22.

[0088] In other embodiments, reference is made to... Figure 11 The annular sidewall 22 includes a sidewall inclined portion 224 extending from a position near the bottom 24 toward the housing 5, and the first air inlet 21 is disposed on the sidewall inclined portion 224.

[0089] The annular sidewall 22 can be a one-piece molded component, with the inclined sidewall portion 224 formed as part of the annular sidewall 22 during the one-piece molding process. Alternatively, the annular sidewall 22 can be composed of multiple independent sub-components, with the inclined sidewall portion 224 being an independent sub-component of the annular sidewall 22, which can be molded independently and connected to the other sub-components of the annular sidewall 22.

[0090] In some non-limiting embodiments, the included angle between the inclined sidewall portion 224 and the bottom 24 is greater than 90° and less than 180°, that is, the included angle between the inclined sidewall portion 224 and the bottom 24 is an obtuse angle. Further, the included angle between the inclined sidewall portion 224 and the bottom 24 is greater than 90° and less than or equal to 150°.

[0091] It should be noted that, Figure 11 The cylinder body 2 shown in the diagram is rectangular, meaning its cross-section along the horizontal direction is rectangular. In practice, the cylinder body 2 can also be cylindrical, meaning its cross-section along the horizontal direction is circular. The cylinder body 2 can also be conical, meaning its cross-section along the horizontal direction is triangular. It should be noted that the cylinder body 2 can also have other shapes, which will not be listed here.

[0092] In some other embodiments, the housing 5 includes an annular housing portion and an upper edge of the housing extending from the top of the annular housing portion toward the ash collection portion, wherein the first air inlet 21 is continuously disposed on the upper edge of the housing portion and the annular housing portion.

[0093] In some other embodiments, the housing 5 includes a sloping portion of the housing extending from a position near the top of the housing toward a direction away from or toward the ash collection portion, and the first air inlet 21 is disposed on the sloping portion of the housing.

[0094] The layout of the first air inlet 21 on the housing 5 can refer to the layout of the first air inlet 21 on the cylinder 2.

[0095] In some other embodiments, the foregoing embodiments can be combined, with the first air inlet 21 being simultaneously disposed on the housing 5 and the cylinder 2.

[0096] In some non-limiting embodiments, the width of the first air inlet 21 can be in the range of 1mm to 2mm.

[0097] In some embodiments, along the arrangement direction of the first air inlets 21, the minimum distance between adjacent first air inlets 21 is greater than or equal to 1 mm. Further, the minimum distance between adjacent first air inlets 21 is greater than or equal to 1 mm and less than or equal to 10 mm. Thus, by rationally arranging the spacing between adjacent first air inlets 21, while facilitating the processing of the first air inlets 21, a good air intake volume can also be achieved, resulting in a better air purification effect.

[0098] The shape of the first air inlet 21 can be elongated, circular, elliptical, or a regular shape such as a square or triangle, or other suitable irregular shapes.

[0099] In some embodiments, the plurality of first air inlets 21 are evenly spaced to improve the uniformity of air intake. It is understood that, depending on the arrangement of other components on the ashtray 100, the plurality of first air inlets 21 may also be non-uniformly arranged according to actual needs.

[0100] In some embodiments, the distance between the plurality of first air inlets 21 and the bottom 24 of the cylinder 2 is greater than zero. For example, the distance between the first air inlets 21 and the bottom 24 is configured to be greater than a set distance range. This set distance range is related to the length of the first air inlet 21 on the annular sidewall 22. For example, if the length of the first air inlet 21 on the annular sidewall is greater than or equal to 3% and less than or equal to 50% of the height of the annular sidewall, then the distance between the first air inlet 21 and the bottom 24 is greater than 50% of the height of the annular sidewall. In this way, the probability of ash and other contaminants entering the filter assembly 3 through the first air inlets 21 can be reduced, and liquids (such as water) accidentally poured into the cylinder 2 can be prevented from entering the ashtray 100 through the first air inlets 21, thus protecting the electrical components inside the ashtray 100 from damage. In addition, the size of the first air inlet 21 can be ensured while balancing the air intake volume and the storage space capacity of the ash collection section 28.

[0101] In practical applications, besides the arrangement of the first air inlet 21 exemplified above, the first air inlet 21 can also be arranged in other ways, as long as both the horizontal component in the horizontal direction and the vertical component in the vertical direction of the first air inlet 21 are non-zero. The fact that both the horizontal and vertical components of the first air inlet 21 are non-zero indicates that, from the perspective of the first air inlet 21 as a whole, there are at least some parts with non-zero horizontal components and also some parts with non-zero vertical components. For example, any part of the first air inlet 21 could have non-zero horizontal and vertical components. Or, for instance, one part of the first air inlet 21 could have a non-zero horizontal component but a zero vertical component, while another part of the first air inlet 21 could have a non-zero vertical component but a zero horizontal component.

[0102] This ensures that the first air inlet 21 has an portion facing upwards towards the cylinder 2 and an portion facing towards the ash collection section 28, thereby helping the fan assembly 4 to draw air above and around the ash collection section 28 through the first air inlet 21. During use, once the user places a cigarette near the area surrounding the ashtray 100, air carrying the smell of smoke will be drawn in through the first air inlet 21. The air flows through at least a portion of the cavity of the ash collection section 28 before entering the filter assembly 3, where it is filtered, thus purifying the smoke in the air. In this way, while increasing the coverage area that the first air inlet 21 can draw in smoke, the collection effect, purification effect, and purification efficiency of the smoke are improved.

[0103] In some embodiments, the filter assembly 3 and the fan assembly 4 are located at least within the housing 5. The housing 5 is provided with an air outlet 51. When the fan assembly 4 is turned on, it can cause air to enter from the first air inlet 21, and after being filtered by the filter assembly 3, the air can be purified. The purified air flows out of the housing 5 through the air outlet 51.

[0104] In some non-limiting embodiments, after air enters through the first air inlet 21, it first flows through the filter assembly 3 for filtration. The filtered air then flows through the fan assembly 4 and is output through the exhaust port of the fan assembly 4 and the air outlet 51 on the housing 5. Preferably, the exhaust port and the air outlet 51 of the fan assembly 4 are positioned correspondingly. In this way, by placing the filter assembly 3 upstream of the fan assembly 4, the air flowing through the fan assembly 4 is filtered by the filter assembly 3, resulting in a higher level of cleanliness of the air flowing through the fan assembly 4. This can prevent impurities such as soot from entering the fan assembly 4 and affecting its normal operation, thereby extending the service life of the fan assembly 4 and reducing the frequency of cleaning and maintenance.

[0105] In practical implementation, the cylinder block 2 has various structural styles depending on the needs of the actual application scenario. The following description, in conjunction with the attached drawings, illustrates some of the structural styles of the cylinder block 2.

[0106] In some embodiments, combined with Figure 10 The annular sidewall 22 includes a first sidewall portion 221 and a second sidewall portion 222. The distance between the first sidewall portion 221 and the center of the ash collection part 28 is less than the distance between the second sidewall portion 222 and the center of the ash collection part 28. That is, the first sidewall portion 221 is recessed towards the center of the ash collection part 28. The first sidewall portion 221 can be an arc-shaped wall, a straight wall, a wavy wall, or other suitable shapes. Figures 1 to 6 , Figure 10 In the example, the first side wall portion 221 is a straight wall and the second side wall portion 222 is an arc-shaped wall.

[0107] The cylinder 2 is located inside the housing 5, and the distance between the first sidewall portion 221 and the housing 5 is greater than the distance between the second sidewall portion 222 and the housing 5. Multiple first air inlets 21 are provided on both the first sidewall portion 221 and the second sidewall portion 222. Since air flows through the air duct space between the first sidewall portion 221 and the housing 5, and the air duct space between the second sidewall portion 222 and the housing 5, configuring the air duct space between the first sidewall portion 221 and the housing 5 to be larger than the air duct space between the second sidewall portion 222 and the housing 5 provides a relatively larger air duct space for airflow. This results in a larger amount of air entering through the first air inlet 21 on the first sidewall portion 221 compared to the amount of air entering through the first air inlet 21 on the second sidewall portion 222, thereby increasing the total amount of air drawn into the ashtray 100 per unit time. This improves airflow efficiency while maintaining the storage capacity of the ash collection section 28, thus improving filtration efficiency.

[0108] In practice, the cylinder 2 can be mounted on the housing 5 in various ways. Examples are given below.

[0109] For example, the cylinder body 2 can be supported on the housing 5. A connecting portion for connecting the cylinder body 2 is provided inside the housing 5. The cylinder body 2 is movably placed inside the housing 5 via the connecting portion. The connecting portion can be a protrusion provided on the inner wall of the housing 5, and the cylinder body 2 is supported on the protrusion. Specifically, the upper edge 23 of the cylinder body is supported on the protrusion. The protrusion can be integrally formed on the housing 5, or it can be connected to the inner wall of the housing 5 by a suitable method such as bonding or snap-fitting.

[0110] For example, an inner shell can be provided inside the outer shell 5, and the inner shell is connected to the outer shell 5. A connecting part is provided on the inner shell, and the cylinder 2 is movably placed inside the outer shell 5 through the connecting part. The connecting part can be a protrusion provided on the inner shell, and the cylinder 2 is supported on the protrusion. Specifically, the upper edge 23 of the cylinder 2 is supported on the protrusion. The protrusion can be integrally formed on the inner shell, or it can be connected to the inner shell by a suitable method such as bonding or snap-fitting. The material of the inner shell can be different from that of the outer shell 5. For example, the outer shell 5 can be a metal shell, and the inner shell can be a plastic shell. In this way, while taking into account the overall strength and appearance of the ashtray 100, the inner shell can also facilitate the formation of the connecting part of the cylinder 2.

[0111] For example, refer to Figures 1 to 6 An ash collection support 8 can be provided inside the housing 5. The ash collection support 8 is connected to the housing 5 and is used to support the cylinder 2 inside the housing 5. A support edge 81 can be provided on the top of the ash collection support 8. The upper edge 23 of the cylinder 2 is supported by the support edge 81. In this way, it is convenient to install and disassemble the cylinder 2, improve the convenience of cleaning the ash or cigarette butts in the ash collection part 28, and facilitate the removal of the cylinder 2 for maintenance of other components (such as the filter assembly 3 or the fan assembly 4).

[0112] The ash collection support part 8 has a hollow structure so that the gas output from the first air inlet 21 can flow out smoothly and enter the filter assembly 3.

[0113] Furthermore, the ashtray 100 also includes a positioning component 9. The positioning component 9 is used for positioning the ashtray body 2 during installation to improve the assembly accuracy of the ashtray body 2. The positioning component 9 may include a positioning groove 91 disposed on one of the ashtray body 2 and the ash collection support 8, and a positioning protrusion 92 disposed on the other of the ashtray body 2 and the ash collection support 8. The positioning groove 91 and the positioning protrusion 92 are adapted to each other, with the positioning protrusion 92 located within the positioning groove 91. Figures 1 to 6 The illustration is based on the example of a positioning groove 91 being set on the cylinder body 2 and a positioning protrusion 92 being set on the ash collection support part 8.

[0114] The number of positioning components 9 can be multiple. The figure shows three positioning components 9 as an example. In practice, there can be one, two or more, depending on the storage space requirements of the cylinder body 2 and the position positioning accuracy requirements.

[0115] In other embodiments, see Figures 13 to 16 The annular sidewall 22 is circular. Multiple first air inlets 21 are evenly distributed at intervals on the annular sidewall 22.

[0116] In some non-limiting embodiments, see Figures 13 to 16The cylinder body 2 includes an outer wall 27 surrounding the annular sidewall 22. The outer wall 27 is connected to the upper edge 23 of the cylinder body. The space between the outer wall 27 and the annular sidewall 22 serves as an air passage. Air entering through the first air inlet 21 enters the filter assembly 3 via this air passage.

[0117] From the top to the bottom of the cylinder 2, along the radial direction of the cylinder 2 (that is, the radial direction of the ash collection part 28), the distance between the outer side wall 27 and the annular side wall 22 gradually increases.

[0118] Furthermore, from the top to the bottom of the cylinder 2, along the radial direction of the cylinder 2, the annular sidewall 22 gradually slopes towards the interior of the cylinder 2, so that the radial dimension of the ash collection portion 28 gradually decreases from the top to the bottom of the cylinder 2. This inclined arrangement of the annular sidewall 22 helps guide the airflow direction of the air output from the first air inlet 21, avoids obstructing airflow, and improves the smoothness of airflow.

[0119] The outer wall 27 of the cylinder body 2 can be integrated into the overall appearance of the ashtray 100. Specifically, the cylinder body 2 can be positioned on the top of the housing 5. The outer wall 27 can be flush with the housing 5 to improve aesthetic consistency. For example, the cylinder body 2 can be magnetically connected to the top of the housing 5. Specifically, the outer wall 27 of the cylinder body 2 can be made of metal, and a magnetic part is provided on the top of the housing 5, with the outer wall 27 magnetically attracted to the magnetic part. Alternatively, a magnetic conductor can be provided at the bottom of the outer wall 27, and a magnetic part can be provided on the top of the housing 5, with the magnetic conductor and the magnetic part magnetically attracted to each other. Or, a magnetic part can be provided at the bottom of the outer wall 27, and a magnetic conductor can be provided on the top of the housing 5, with the magnetic conductor and the magnetic part magnetically attracted to each other. Another example is that the cylinder body 2 can be threaded onto the top of the housing 5. Yet another example is that the cylinder body 2 can be snap-fitted onto the top of the housing 5. It should be noted that other methods can also be used to connect the cylinder body 2 to the top of the housing 5, which will not be listed here.

[0120] In some modified embodiments, the cylinder body 2 may have an outer wall 27 of an annular sidewall 22. The outer wall 27 may be annular. The annular sidewall 22 may include a first sidewall portion 221 and a second sidewall portion 222, wherein the distance between the first sidewall portion 221 and the center of the ash collection portion 28 is less than the distance between the second sidewall portion 222 and the center of the ash collection portion 28.

[0121] Reference Figure 12 , Figures 17 to 21 In the above Figure 11 , Figures 13 to 16 Based on the schematic cylinder 2, a guide column 25 is provided at the bottom 24 of the cylinder 2. The guide column 25 can be used to guide the flow direction of the airflow to improve the air intake effect of the first air inlet 21.

[0122] In some embodiments, the guide column 25 is disposed in the central region of the bottom 24 of the cylinder body 2.

[0123] Furthermore, in some embodiments, the guide column 25 is provided with a second air inlet 29 in its circumferential direction. While guiding the intake airflow, the guide column 25, together with the second air inlet 29, can further increase the air intake area, which helps to draw in more air per unit time, thereby improving the absorption effect of flue gas and the air purification effect.

[0124] There can be multiple second air inlets 29. Multiple second air inlets 29 are evenly spaced along the circumferential direction of the guide column 25.

[0125] In some embodiments, the guide column 25 is open toward the filter assembly 3 to facilitate airflow into the filter assembly 3 via the second air inlet 29 on the guide column 25. For example, the guide column 25 is a hollow structure.

[0126] In some embodiments, the top of the flow guide column 25 is sealed, and the bottom of the flow guide column 25 is open toward the filter assembly 3.

[0127] In some non-limiting embodiments, the size of the guide column 25 gradually increases in the radial direction of the cylinder 2 from the top to the bottom 24. That is, both the outer and inner diameters of the guide column 25 gradually increase in the radial direction of the cylinder 2 from the top to the bottom 24. This helps to guide external air into the second air inlet 29 of the guide column 25 and also helps to guide air smoothly out of the second air inlet 29, avoiding interference with airflow.

[0128] The second air inlet 29 is located in the upper middle part of the guide column 25, and the distance between it and the bottom 24 of the cylinder body 2 is not zero. In this way, the probability of soot collected in the soot collection section 28 entering the second air inlet 29 with the air can be reduced, thereby reducing the amount of impurities accumulated in the filter assembly 3 and reducing the frequency of replacement or cleaning of the filter assembly 3.

[0129] Reference Figure 12 , Figures 22 to 25A guide cover 26 is provided on the top of the guide column 25. Along the radial direction of the ash collection part 28, the size of the guide cover 26 is larger than the size of the guide column 25. The guide cover 26 on the top of the guide column 25 helps to force airflow into the second air inlet 29, forming a "converging" air intake effect. This helps to improve the uniformity of flow distribution and flow field stability of each second air inlet 29, and also helps to form a negative pressure area near the guide column 25. This negative pressure area can cause the surrounding air to flow towards the ashtray 100, so that more air enters from the first air inlet 21 and the second air inlet 29, increasing the amount of air that the ashtray 100 can purify per unit time and improving the air purification effect.

[0130] In some non-limiting embodiments, the flow guide cap 26 may be higher than the top of the cylinder body 2, or it may be flush with or lower than the top of the cylinder body 2.

[0131] In some non-limiting embodiments, the flow guide 26 may be disc-shaped, and the top of the flow guide 26 may be arc-shaped.

[0132] In some embodiments, along the radial direction of the ash collection section 28, the size of the guide cover 26 is greater than or equal to 20% and less than or equal to 50% of the size of the ash collection section 28. In this way, both the storage space of the ash collection section 28 and the air intake effect per unit time can be taken into account.

[0133] In practice, the shapes of the ashtray 100 and the cylinder body 2 are not limited to... Figures 1 to 25 As shown in the illustration. In some variations, the ashtray 100 and the cylinder body 2 can also have other structural styles, which will not be listed here.

[0134] To more intuitively demonstrate the air purification range and effect of the ashtray 100 provided in this application, comparative examples and implementation examples are set below, and simulations are performed on the comparative examples and implementation examples. The simulation results are as follows. Figures 35 to 39 As shown.

[0135] In Comparative Example 1, an air inlet is provided only on the side wall of the cylinder body 2. In Comparative Example 2, a first air inlet is provided only on the side wall of the cylinder body, a guide column is provided at the bottom of the cylinder body, and a second air inlet is provided on the side wall of the guide column. In Embodiment 1, the structure of the cylinder body 2 of the ashtray 100 is as follows: Figure 13 As shown. In Embodiment 2, the structure of the cylinder body 2 of the ashtray 100 is as follows. Figure 17 As shown. In Embodiment 3, the structure of the ash collection section 28 of the ashtray 100 is as follows. Figure 22 As shown. In the comparative example and the embodiment, the ashtrays do not include a cover assembly and are the same size.

[0136] Among them, combined Figures 37 to 39 The following are equivalent schematic diagrams of the air inlet surface 200 and air outlet surface 300 in Example 3 from different perspectives. It should be noted that the air inlet surface 200 and air outlet surface 300 of Comparative Example 1, Comparative Example 2, Example 1, and Example 2 are the same as those of Example 3, and will not be shown individually here. The following is in conjunction with... Figure 37 and Figure 39 To illustrate the simulation conditions, specifically, the ashtray 100 in the comparative example and embodiment is configured under the following simulation conditions: the air inlet surface 200 of the ashtray 100 is simulated as an equivalent sphere, with an equivalent sphere diameter approximately three times the diameter of the ashtray body. The static pressure difference between the air inlet surface 200 and the external atmospheric environment is 0 Pa. The bottom circular surface of the ashtray body 2 is equivalent to the air outlet surface 300. The static pressure of the air outlet surface 300 is configured as -200 Pa. The static pressure at the outlet surface 300 is lower than that at the inlet surface 200. Utilizing the pressure difference between the inlet surface 200 and the outlet surface 300, a negative pressure can be created near the outlet surface 300. This negative pressure forces air to enter through the first inlet 21 and / or the second inlet 29, simulating the function of the air intake assembly 4 in guiding air in through the first inlet 21 and / or the second inlet 29. The air then enters from the inlet surface 200 through the first inlet 21 and / or the second inlet 29, passes through the filter assembly, and flows to the outlet surface 300 for output. By configuring the pressure difference between the inlet surface 200 and the outlet surface 300 to simulate the function of the fan assembly 4, the power limitation of the fan assembly 4 can be eliminated, better reflecting the air intake effect of the first inlet 21 and / or the second inlet 29.

[0137] Under the above simulation conditions, the airflow velocity (in m / s) around the ashtrays in the comparative and embodiment examples was simulated, and the simulation results are as follows. Figure 35 as well as Figure 36 As shown. Among them Figure 36 The subgraphs (a), (b), (c), (d), and (e) are Figure 35 The corresponding sub-figures (a), (b), (c), (d), and (e) are sectional views passing through the center of the storage section and along the vertical direction. For ease of explanation, they will be referred to later in the text. Figure 35 (a), (b), (c), (d), and (e) are abbreviated as follows: Figure 35 (a) Figure 35 (b) Figure 35 (c) Figure 35 (d) Figure 35 (e); will Figure 36 (a), (b), (c), (d), and (e) are abbreviated as follows: Figure 36 (a) Figure 36 (b) Figure 36 (c) Figure 36 (d) Figure 36 (e). Figure 35 (a) is a simulation diagram for comparison with Example 1. Figure 35 (b) is a simulation diagram for comparison with Example 2. Figure 35 (c) is a simulation diagram of Example 1. Figure 35 (d) is a simulation diagram of Example 2. Figure 35 (e) is a simulation diagram of Example 3. Figure 36 (a) is Figure 35 (a) Sectional view; Figure 36 (b) is Figure 35 (b) sectional view; Figure 36 (c) is Figure 35 (c) Sectional view; Figure 36 (d) is Figure 35 (d) Sectional view; Figure 36 (e) is Figure 35 (e) is a sectional view.

[0138] from Figure 35 and Figure 36 In the simulation results shown, the deeper the blue color, the lower the airflow velocity, indicating poorer air intake within the low-velocity blue region. The yellow and red regions exhibit higher airflow velocities. The airflow velocity near the first and / or second air inlets directly affects the airflow volume of the ashtray; therefore, the simulation results focus on the airflow velocity in the areas near the first and second air inlets. The airflow state of the air already entering the ashtray through the first and / or second air inlets does not substantially affect the airflow volume.

[0139] In the simulation results, compare Figure 35 (a) and Figure 35 (c) Figure 36 (a) and Figure 36 (c) It can be seen that, Figure 35 (c) and Figure 36 (c) Compared to the yellow and red areas with medium to high flow velocities Figure 36 (a) and Figure 35 (a) is significantly increased. In other words, when the first air inlet 21 of the ashtray in Example 1 is continuously located on the top of the annular sidewall and the upper edge of the ashtray body, it can significantly increase the coverage area of ​​high-velocity air, increase the air intake volume, and increase the coverage area of ​​the smoke that can be absorbed.

[0140] contrast Figure 35 (b) and Figure 35 (d) Figure 36 (b) and Figure 36 (d) It can be seen that in the vicinity of the first air inlet and the second air inlet, Figure 35 (d) and Figure 36 (d) The yellow and red areas with medium to high flow velocities are both compared to Figure 36 (b) and Figure 35 (b) shows a significant increase.

[0141] contrast Figure 35 (a) and Figure 35 (b) Figure 35 (c) and Figure 35 (d) Figure 36 (a) and Figure 36 (b) Figure 36 (c) and Figure 36 (d) It can be seen that by adding a guide column with a second air inlet to the cylinder, Figure 35 (b), 35 (d) Figure 36 (b) and Figure 36 (d) The area of ​​the yellow region and the area of ​​the red region in the medium-to-high flow velocity region compared to 35(a), Figure 35 (c) Figure 36 (a) and Figure 36 In (c), the areas of the high-velocity yellow and red regions are further increased, while the area of ​​the low-velocity blue region is further reduced. Therefore, the design of the first and second air inlets in Example 2 can further increase the area of ​​high-velocity air, increase the air intake volume, and increase the coverage area of ​​the absorbed flue gas.

[0142] based on Figure 35 (b) Figure 35 (d) Figure 35 (e) Figure 36 (b) Figure 36 (d) Figure 36 (e) It can be seen that, Figure 35 (e) and Figure 36 (e) Comparison of the area of ​​the yellow region and the area of ​​the red region in the medium-to-high flow velocity region Figure 35 (b) Figure 35 (d) Figure 36 (b) Figure 36 (d) is further increased. Figure 35 (e) The blue low-velocity area corresponds to the area above the air guide cover, where the air velocity is low due to the obstruction of the air guide cover. The areas outside the air guide cover are primarily high-velocity air zones (yellow and red). The design of the first and second air inlets in Embodiment 3 further increases the area of ​​high-velocity air, increases the air intake volume, and increases the coverage area of ​​the absorbed flue gas. In other words, the design of the first and second air inlets in Embodiment 3 provides better air intake and air purification.

[0143] In specific implementations, based on any of the above embodiments, see [link to relevant documentation]. Figures 2 to 6 as well as Figures 26 to 34 The ashtray 100 also includes a cover assembly 1, which is used to open or close the ash collection section 28.

[0144] In some embodiments, the cover assembly 1 can be a solid cover. After the cover is placed on the housing 5, the housing 5 and the cylinder 2 can be closed to prevent ash from escaping from the ash collection part 28. The solid cover can be magnetically attached to the housing 5 or threadedly connected to the housing 5. When using the ashtray 100, the solid cover is removed from the housing 5, and after the ashtray 100 is finished being used, the solid cover is placed back on the housing 5.

[0145] Furthermore, the solid lid may also have perforations. There can be multiple perforations, corresponding to the positions of the first air inlet 21 and / or the second air inlet 29. For example, multiple perforations may be located above the first air inlet 21 and / or the second air inlet 29. In some scenarios, when the user is only smoking and does not need to dispose of ash or cigarette butts, the perforations can absorb smoke without removing the solid lid, improving the ease of use of the ashtray 100.

[0146] In some other embodiments, the cover assembly 1 includes a cover 11 with a first opening 111. The first opening 111 communicates with at least one of the first air inlet 21 and the ash collection part 28, so that air can enter from the first opening 111 via the first air inlet 21. Thus, without removing the cover assembly 1 from the housing 5, the first opening 111 allows for the absorption of smoke and the disposal of ash or cigarette butts, improving the ease of use of the ashtray 100.

[0147] The first opening 111 is located above the ash collection section 28. When cigarette butts or ash are placed in the ash collection section 28, the cigarette butts or ash can fall accurately into the ash collection section 28 through the first opening 111.

[0148] Furthermore, in some embodiments, the cover assembly 1 further includes an opening / closing cover 12. The opening / closing cover 12 is movably connected to the cover 11 to open or close the first opening 111.

[0149] In some non-limiting embodiments, a cigarette support portion 112 may also be provided on the cover 11. The cigarette support portion 112 is used to place and support the cigarette. The cigarette support portion 112 can be a groove. The cigarette is clamped in the groove. The cigarette support portion 112 can be provided at the edge of the first opening 111, so that after the cigarette is placed in the cigarette support portion 112, the cigarette butt can be located above the first opening 111 or extend into the ash collection portion 28. This can improve the smoke collection effect and allow the ash to fall naturally into the ash collection portion 28, preventing the ash from scattering outside the ashtray 100.

[0150] In some non-limiting embodiments, the opening size of the ash collection part 28 is larger than the size of the first opening 111, so as to improve the convenience of disposing of cigarette butts or ash and reduce the probability of cigarette butts or ash falling outside the ash collection part 28.

[0151] When cigarette butts or ash need to be disposed of, or when the smoke needs to be purified during smoking, the opening and closing cover 12 moves relative to the cover 11, opening the first opening 111 on the cover 11 to expose the ash collection part 28. At this time, air enters from the first air inlet 21. After the cigarette butts or ash have been disposed of, the opening and closing cover 12 moves relative to the cover 11, closing the first opening 111 on the cover 11 to close the ash collection part 28 and prevent cigarette butts or ash from coming out of the ash collection part 28.

[0152] In specific implementations, the opening and closing cover 12 can be connected to the cover body 11 in various ways, and the movement of the opening and closing cover 12 relative to the cover body 11 will differ depending on the connection method. For example, when the opening and closing cover 12 is hinged to the cover body 11 using a hinge, pivot, or other means, the opening and closing cover 12 can flip relative to the cover body 11 around the hinge point, i.e., a flip-top opening and closing mechanism. Another example is that the opening and closing cover 12 can move relative to the cover body 11 in a plane parallel to the cover body 11.

[0153] In practice, the movement of the opening and closing cover 12 relative to the cover body 11 can be achieved in various ways. Examples are given below.

[0154] For example, the user can directly move the opening and closing cover 12, causing the opening and closing cover 12 to move relative to the cover body 11.

[0155] For example, the opening and closing cover 12 is provided with an operating part, which is used to drive the opening and closing cover 12 to move relative to the cover body 11. The operating part can be an operating handle or a lever, etc.

[0156] For example, a knob is coupled to the opening and closing cover 12. By rotating the knob, the opening and closing cover 12 can be moved relative to the cover body 11.

[0157] For example, combining Figures 26 to 34 The cover assembly 1 further includes a drive unit 131 and a moving unit, the moving unit being connected to the opening / closing cover 12. The drive unit 131 drives the moving unit, which in turn drives the opening / closing cover 12 to open or close the first opening 21. Here, closing the first opening 21 means that the opening / closing cover 12 blocks the first opening 21, preventing it from communicating with the ash collection part 28. Opening the first opening 21 means that the opening / closing cover 12 does not block the first opening 21, allowing communication between the first opening 21 and the ash collection part 28, enabling ash or cigarette butts to fall into the ash collection part 28 through the first opening 21.

[0158] In some embodiments, the drive unit 131 may be provided with a rack 1312. The drive unit 131 is movable relative to the cover 11. The moving part includes a cover plate gear 132, and the rack 1312 meshes with the cover plate gear 132.

[0159] In some embodiments, the drive unit 131 includes a slider 1311 configured to move relative to the cover 11, and the slider 1311 is provided with a rack 1312.

[0160] In some embodiments, the slider 1311 may rotate in the circumferential direction of the cover 11.

[0161] In some non-limiting embodiments, the axis of rotation of the slider 1311 relative to the cover 11 is the same as the axis of rotation of the opening / closing cover 12 relative to the cover 11. This improves the accuracy of the slider 1311 in driving the opening / closing cover 12 and also increases power transmission efficiency.

[0162] In some non-limiting embodiments, the axis of rotation of the opening and closing cover 12 relative to the cover 11 coincides with the central axis of the ashtray 100.

[0163] In some embodiments, the cover 11 is provided with a second opening 118 for exposing a portion of the slider 1311. This allows the slider 1311 to be easily driven.

[0164] In some embodiments, the slider 1311 is provided with a toggle part 1313, and the cover 11 is provided with a second opening 118 for exposing the toggle part 1313. The toggle part 1313 provides an operating part for the user to operate the slider 1311, improving the convenience of the user's operation of the slider 1311. When the user needs to dispose of cigarette ash or cigarette butts or needs to purify the smoke, the user can toggle the toggle part 1313, which drives the slider 1311 to move, causing the opening and closing cover 12 to move relative to the cover 11 to open the first opening 111 and expose the ash collection part 28. When the disposition of cigarette ash or cigarette butts is completed or the purification of the smoke is no longer needed, the toggle part 1313 is toggleed in the opposite direction, which drives the slider 1311 to move, causing the opening and closing cover 12 to move relative to the cover 11 to close the first opening 111.

[0165] like Figure 29 and Figure 32 As shown, the actuating part 1313 can be disposed on the top of the slider 1311, in which case the second opening 118 is disposed on the top of the cover 11. The actuating part 1313 can also be disposed on the side of the slider 1311, and correspondingly, the second opening 118 is disposed on the side of the cover 11.

[0166] The actuating part 1313 can be a protrusion protruding from the slider 1311, a handle, or a knob, or other suitable structural style.

[0167] In some non-limiting embodiments, the size of slider 1311 is larger than the size of the second opening 118 along the direction of movement of slider 1311. Furthermore, the size of slider 1311 is at least twice the size of the second opening 118 along the direction of movement of slider 1311. This ensures that as slider 1311 moves from a closed state to an open state, it can always close the second opening 118, preventing foreign objects from entering the ashtray 100 through the second opening 118. "Slider 1311 can always close the second opening 118" means that slider 1311 always blocks the second opening 118.

[0168] In some embodiments, to allow users to more intuitively understand whether the slider 1311 is opening or closing the cover 12, an open or closed indicator can be provided on the surface of the cover 11. For example, see... Figure 29 and Figure 32The cover 11 is provided with an "ON" sign for opening and an "OFF" sign for closing. When the toggle part 1313 on the slider 1311 corresponds to the "OFF" sign, the cover 12 is in the closed state of the first opening 111. As the slider 1311 moves from the "OFF" position towards the "ON" position, the first opening 111 gradually opens. When the toggle part 1313 on the slider 1311 corresponds to the "ON" sign, the first opening 111 is in the fully open state. It should be noted that the "ON" sign for opening can also be "OP," and the "OFF" sign can also be "LOC," or other signs can be used, which will not be listed here.

[0169] In some embodiments, combined with Figure 27 To improve the stability of the slider 1311 relative to the cover 11 during movement, the cover assembly 1 further includes a first guide mechanism 14. The first guide mechanism 14 is used to guide the movement trajectory of the slider 1311 relative to the cover 11, so that the slider 1311 moves relative to the cover 11 along a set trajectory.

[0170] The first guide mechanism 14 guides the slider 1311 to move in an arc-shaped trajectory relative to the cover 11.

[0171] The first guiding mechanism 14 may include a first guide rail 141 disposed on one of the cover 11 and the slider 1311, and a first guide groove 142 disposed on the other of the cover 11 and the slider 1311, wherein the first guide groove 142 and the first guide rail 141 are adapted to each other. Figures 26 to 34 The illustration is given with the first guide groove 142 set on the slider 1311 and the first guide rail 141 set on the cover 11 as an example.

[0172] In a specific implementation, a stop portion 15 is provided on the cover 11, which is used to limit the rotational position of the slider 1311. For example, the stop portion 15 is used to limit the maximum movement position of the slider 1311 relative to the cover 11. The stop portion 15 can be a protruding rib protruding from the cover 11.

[0173] Furthermore, there can be two stop portions 15, with the slider 1311 located between the two stop portions 15. The two stop portions 15 can limit the movement of the slider 1311 in the forward and reverse directions, respectively.

[0174] In some embodiments, the rack 1312 may directly mesh with the cover gear 132.

[0175] For example, a first rotating shaft 113 may be provided on the cover 11. The cover plate gear 132 is sleeved on the first rotating shaft 113 and fixedly connected to the opening and closing cover plate 12. When the slider 1311 moves, the rack 1312 on the slider 1311 meshes with the cover plate gear 132, driving the cover plate gear 132 to rotate, thereby driving the opening and closing cover plate 12 to move.

[0176] In other embodiments, the cover assembly 1 further includes a transmission unit connected to the drive unit 131 and the motion unit, for transmitting power from the drive unit 131 to the motion unit.

[0177] In some non-limiting embodiments, the transmission unit includes a transmission gear set 133, which meshes with the rack 1312 and the cover plate gear 132. Power is transmitted from the slider 1311 to the opening / closing cover plate 12 via the transmission gear set 133.

[0178] Specifically, a first rotating shaft 113 may be provided on the cover 11. The cover plate gear 132 is sleeved on the first rotating shaft 113 and fixedly connected to the opening and closing cover plate 12. A rotating shaft for mounting the transmission gear set 133 is provided on the cover 11. When the slider 1311 moves, the rack 1312 on the slider 1311 meshes with the transmission gear set 133 to drive the transmission gear set 133 to rotate. When the transmission gear set 133 rotates, it will drive the cover plate gear 132 meshing with it to rotate, thereby driving the opening and closing cover plate 12 to move, so that the slider 1311 drives the opening and closing cover plate 12 to move through the transmission gear set 133.

[0179] The transmission gear set 133 transmits power between the slider 1311 and the opening / closing cover 12, allowing them to rotate in the same direction and improving the consistency of their movements. The transmission gear set 133, acting as an intermediate bridge between the rack 1312 and the cover gear 132, increases the transmission distance, adapting to the internal space arrangement requirements of the cover assembly 1. Without changing the transmission ratio of the rack 1312 and the cover gear 132, it solves the problem of the rack 1312 and cover gear 132 being unable to directly mesh due to space constraints.

[0180] The transmission gear set 133 may include one or more transmission gears 1331. The number of transmission gears 1331 may be selected based on factors such as the transmission distance between the slider 1311 and the opening / closing cover 12, and the number of teeth of the rack 1312 and the cover gear 132.

[0181] For example, Figures 27 to 34The transmission gear set 133, comprising two transmission gears 1331, is illustrated as an example. The two transmission gears 1331 are identical. A second rotating shaft 114 and a third rotating shaft 115 can be mounted on the cover plate 12. The two transmission gears 1331 are respectively fitted onto the second rotating shaft 114 and the third rotating shaft 115.

[0182] Furthermore, the transmission gear 1331 is the same as the cover gear 132.

[0183] In some non-limiting embodiments, rack 1312 is an internal rack. The axis of rack 1312 is the same as the axis of cover gear 132. The radius of rack 1312 is larger than the radius of cover gear 132.

[0184] In some embodiments, the tooth ratio of the rack 1312 and the cover gear 132 ranges from 1:1 to 9:1.

[0185] Furthermore, the gear ratio of the rack 1312 and the cover gear 132 ranges from 3:1 to 6:1. In this way, while improving the ease of user operation, the operability of the drive unit 131 can be ensured.

[0186] That is, the number of teeth on rack 1312 is greater than or equal to the number of teeth on cover gear 132. When the number of teeth on rack 1312 is greater than the number of teeth on cover gear 132, a smaller rotation of slider 1311 can drive the opening / closing cover 12 to rotate a larger angle. The angle of rotation of the opening / closing cover 12 is greater than the angle of rotation of slider 1311, thus improving ease of operation. For example, if the ratio of the number of teeth on rack 1312 to the number of teeth on cover gear 132 is 4:1, then a 45-degree rotation of rack 1312 will result in a 180-degree rotation of the opening / closing cover 12.

[0187] In some embodiments, when the rack 1312, the transmission gear set 133 and the cover gear 132 are connected by gear transmission, the number of transmission stages is less than or equal to 3, so as to take into account the energy transmission efficiency during the transmission process.

[0188] in, Figures 29 to 31 This is a schematic diagram showing the cover 12 in the closed state. Figures 32 to 34 This is a schematic diagram of the opening and closing cover 12 in the open state. In order to intuitively show the transmission part, cover gear 132 and other structures that are covered by the cover body 11, Figure 30 as well as Figure 33 A portion of the structure of the cover 11 is hidden within. Figure 31 as well as Figure 34 The image only shows the relative positions of the opening and closing cover 12, cover gear 132, transmission gear set 133, rack 1312, and slider 1311, while other structures in the cover assembly 1 are hidden.

[0189] In some embodiments, the cover assembly 1 further includes a gear cover 16, which is connected to the cover body 11. The gear cover 16, on the one hand, limits the meshing of the rack 1312 and the transmission gear set 133 in the planar direction, thereby improving the transmission stability of the rack 1312 and the transmission gear set 133; on the other hand, the gear cover 16 can seal at least a portion of the rack 1312 and the transmission gear set 133, preventing foreign matter such as soot from contaminating the rack 1312 and the transmission gear set 133 and affecting their normal operation.

[0190] In some non-limiting embodiments, the gear cover 16 defines the engagement of the transmission gear set 133 and the cover gear 132 in the horizontal direction.

[0191] Furthermore, the gear cover 16 defines the horizontal meshing of the transmission gear set 133, the rack 1312, and the cover gear 132.

[0192] In some embodiments, combined with Figure 26 The gear cover 16 and the opening / closing cover 12 are on different planes. When the opening / closing cover 12 opens the first opening 111, the opening / closing cover 12 covers at least a portion of the gear cover 16. In this way, interference from the gear cover 16, the transmission gear set 133, etc., on the movement of the opening / closing cover 12 can be avoided, which helps the coordinated movement between the various components.

[0193] In some non-limiting embodiments, the cover 11 has a cavity 116 opening toward the ashtray 28, and the opening / closing cover 12, the cover gear 132, and the transmission gear set 133 are all located within the cavity 116. Within the cavity 116, a vertical rib 117 is provided along the edge of the first opening 111. The vertical rib 117 protrudes from the inner surface 11a of the cover 11. Along the top-to-bottom direction of the ashtray 100, the height of the vertical rib 117 is greater than or equal to the thickness of the cover gear 132, thereby allowing the opening / closing cover 12 to conform to the vertical rib 117, thus improving the closing effect of the opening / closing cover 12 on the first opening 111.

[0194] Furthermore, the vertical rib 117 has a clearance portion in the direction away from the center of the cover body 11, which forms a receiving space for the cover plate gear 132 to avoid interference with the cover plate gear 132.

[0195] In some embodiments, the gear cover 16 may be flush with or below the vertical rib 117.

[0196] In some embodiments, combined with Figure 5 , Figure 27 as well as Figure 28The ashtray 100 further includes a second guide mechanism 18. The second guide mechanism 18 includes a second guide groove 182 disposed on one of the gear cover 16 and the slider 1311, and a second guide rail 181 disposed on the other of the gear cover 16 and the slider 1311. The second guide rail 181 is adapted to the second guide groove 182. The figure illustrates an example where the second guide rail 181 is disposed on the side of the slider 1311 facing the gear cover 16, and the second guide groove 182 is disposed on the side of the gear cover 16 facing the slider 1311.

[0197] In some embodiments, the second guide rail 181 is arc-shaped.

[0198] In some embodiments, the cover assembly 1 further includes a limiting cover 17. The limiting cover 17 has a third opening 171 and is connected to the cover 11. The third opening 171 on the limiting cover 17 is configured to expose the first opening 111. By providing the limiting cover 17, the stability of the opening and closing movement of the cover 12 is improved, while the third opening 171 on the limiting cover 17 also avoids obstructing the first opening 111 and the ash collection part 28, ensuring the normal disposal of ash or cigarette butts.

[0199] Furthermore, the third opening 171 corresponds to the position of the first opening 111; for example, the third opening 171 is located above the first opening 111. The size of the third opening 171 is greater than or equal to that of the first opening 111, so as to avoid affecting the falling of ash or cigarette butts when they are disposed of.

[0200] In some embodiments, see Figure 26 The limiting cover 17 covers at least a portion of the opening and closing cover 12.

[0201] In some non-limiting embodiments, the limiting cover 17 may be a metal plate.

[0202] It should be noted that the aforementioned transmission gear set 133 can be a spur gear set or a helical gear set. Besides using the aforementioned transmission gear set 133 for planar motion transmission, the transmission unit can also employ transmission structures capable of changing the direction of motion, such as worm gears, bevel gears, etc. Where technically permissible, the aforementioned transmission gear set 133, worm gears, and bevel gears can be used in combination.

[0203] In other embodiments, the drive unit 131 includes a drive motor, and the transmission unit includes a gear reducer adapted to the drive motor. The cooperation of the drive motor and the gear reducer enables the automatic opening and closing of the cover 12, ensuring smooth operation during its movement.

[0204] The drive motor can be activated in several ways. For example, a switch can be provided on the cover 11 or the housing 5 to turn the drive motor on or off. The switch can be a mechanical button or a touch button. Alternatively, a sensing component can be provided on the cover 11 or the housing 5. When the sensing component detects that the distance between a person and the ashtray 100 is less than or equal to a preset distance, it generates a motor activation signal to turn on the drive motor. When the detected distance between the person and the ashtray 100 is greater than the preset distance, it generates a motor deactivation signal to turn off the drive motor. The motor deactivation signal can be used to immediately turn off the drive motor. Alternatively, it can be used to turn off the drive motor after a preset time, achieving a delayed shutdown of the drive motor to improve the purification effect on the smoke. The sensing component can be an infrared sensor or a proximity switch or other component capable of detecting the distance between a person and the ashtray 100.

[0205] In some embodiments, the ashtray 100 further includes a fan switch 79, which is used to activate the fan assembly 4 when the cover assembly 1 opens the first opening 111.

[0206] In some embodiments, the fan switch 79 is used to turn off the fan assembly 4 when the cover assembly 1 closes the first opening 111.

[0207] By opening or closing the first opening 111 through the cover assembly 1, the fan assembly 4 can be started or stopped in conjunction with it. This can improve the rationality of starting and stopping the fan assembly 4 and its matching degree with user needs, and can also save energy.

[0208] The fan switch 79 includes a status detection component, which is used to detect whether the first opening 111 is open or closed.

[0209] In some embodiments, the open or closed state of the first opening 111 can be indicated by the state of the drive unit 131.

[0210] For example, the status detection component is used to detect the open or closed state of the drive unit 131. When the drive unit 131 is a drive motor, the drive motor being turned on indicates that the cover assembly 1 has opened the first opening 111. The drive motor being turned off indicates that the cover assembly 1 has closed the first opening 111.

[0211] For example, the drive unit 131 is a slider 1311, and the state detection unit can detect the movement state of the slider 1311, which can be the direction of movement. Based on the movement state of the slider 1311, it can be determined whether the slider 1311 drives the opening and closing cover 12 to open or close the first opening 111.

[0212] The status detection component may include a magnetic conductor, a Hall element, a magnetic block, and a control circuit.

[0213] A magnetic conductor is disposed on slider 1311. The magnetic conductor can be a metal block capable of conducting magnetism, such as an iron block.

[0214] The Hall element is located on the top of the housing 5. After the cover assembly 1 is assembled into the housing 5, the Hall element is close to the magnetic conductor to sense changes in the magnetic field. The Hall element is used to convert changes in the magnetic field into an electrical signal output. The Hall element can be a switch-type Hall element.

[0215] Magnetic blocks are arranged in pairs on both sides of the Hall element, with opposite magnetic properties; one is the N pole and the other the S pole. The magnetic blocks can be permanent magnets to ensure a stable magnetic field. The two magnetic blocks and the Hall element together form an initial magnetic field. When a magnetic conductor approaches, the magnetic field is guided or amplified, triggering the Hall element to output a signal. The control circuit, located inside housing 5, converts the electrical signal output by the Hall element into an executable signal to control the opening or closing of the fan assembly 4.

[0216] Specifically, by default, the cover 12 is in the closed state of the first opening 111. A magnetic conductor approaches the Hall element, changing the magnetic field around the Hall element. The Hall element generates a Hall voltage and outputs a first signal to the control circuit. The control circuit controls the fan assembly 4 to close based on the first signal. When it is necessary to open the first opening 111, the slider 1311 begins to move relative to the cover 11. The magnetic conductor on the slider 1311 moves away from the Hall element, the magnetic field returns to its initial state, and the Hall element outputs a second signal to the control circuit. The control circuit controls the fan assembly 4 to open based on the second signal. The first signal can be high-level, and the second signal can be low-level.

[0217] The blower switch 79 can be located at the top of the housing 5, or at various suitable locations such as inside or on the side of the housing 5. When the blower switch 79 is located at the top of the housing 5, the cylinder 2 can be... Figure 1 as well as Figure 10 As shown in the illustration, the annular sidewall 22 includes a first sidewall portion 221 and a second sidewall portion 222. Since the first sidewall portion 221 is recessed towards the interior of the ashtray 28, it provides corresponding space for the installation of the fan switch 9, making the overall layout of the ashtray 100 more compact.

[0218] The first sidewall portion 221 is located below the second opening 118, and / or the second sidewall portion 222 is located below the first opening 111.

[0219] Furthermore, the fan switch 79 is located below the slider 1311.

[0220] In some embodiments, the fan assembly 4 may be a blower. Further, the fan assembly 4 may be an axial flow blower.

[0221] In some embodiments, the blower assembly 4 can be configured with multiple speed settings, each with a different blower speed and a different volume of air absorbed per unit time. A speed adjustment button can be provided on the blower assembly 4 to adjust its speed. The speed adjustment button can be located on the housing 5. The speed adjustment button can be a physical button or a touch button.

[0222] In other embodiments, a smoke concentration detection sensor may be configured, located downstream of the first air inlet 21 and / or the second air inlet 29, to detect the smoke concentration in the air drawn into the ashtray 100. The speed of the fan assembly 4 is determined based on the detected smoke concentration, thereby improving the rationality of the speed determination of the fan assembly 4.

[0223] In some embodiments, the fan assembly 4 is disposed within the housing 5, and the housing 5 is provided with an air outlet 51 corresponding to the exhaust port of the fan assembly 4.

[0224] There can be multiple air outlets 51. The multiple air outlets 51 can be evenly distributed at the positions corresponding to the exhaust ports of the fan assembly 4, or they can be non-evenly distributed at the positions corresponding to the exhaust ports of the fan assembly 4.

[0225] An air outlet 51 may be provided only in the area corresponding to the exhaust port of the fan assembly 4 on the housing 5. Alternatively, while providing an air outlet 51 in the area corresponding to the exhaust port of the fan assembly 4, air outlets 51 may also be provided in other areas of the housing 5 to improve the overall appearance consistency of the ashtray 100.

[0226] The air outlet 51 can be a suitable regular shape such as a strip, square, triangle, circle, or star, or it can be some irregular irregular shape. Multiple air outlets 51 can have the same shape or different shapes.

[0227] In some embodiments, the cover assembly 1 is magnetically disposed above the ash storage portion 28.

[0228] The housing 5 has a receiving cavity, and the cover assembly 1 is magnetically attached to the top of the housing 5. A portion of the cover assembly 1 may be a magnetic conductor. A magnet is provided on the top of the housing 5, and the magnetic attraction between the magnet and the magnetic conductor is achieved.

[0229] Multiple magnetic conductors can be provided on the cover assembly 1, and correspondingly, a corresponding number of magnets can be provided on the top of the housing 5 to improve the magnetic adhesion between the cover assembly 1 and the housing 5 and prevent the cover assembly 1 from falling off the housing 5.

[0230] For example, the fasteners used to fix the limiting cover 17 can be configured as metal parts, and the fasteners of the limiting cover 17 can be reused as magnetic conductors, which can simplify the number of parts, thereby simplifying the overall structure of the ashtray 100 and saving costs.

[0231] In some embodiments, the ashtray 100 may further include a lid positioning assembly. The lid positioning assembly is used for positioning the lid assembly 1 on the housing 5, enabling quick and accurate assembly of the lid assembly 1 onto the housing 5. The lid positioning assembly may include a positioning notch 119 on the lid 11 and a positioning protrusion 52 on the housing 5. The positioning protrusion 52 is adapted to the positioning notch 119, and when the lid assembly 1 is assembled onto the housing 5, the positioning protrusion 52 engages within the positioning notch 119.

[0232] In some embodiments, the filter assembly 3 may include a filter element 31 and a filter element support 32. The filter element support 32 has a filter element receiving cavity 321 for placing the filter element 31. The filter element support 32 may be connected to the housing 5.

[0233] Among them, filter element 31 can be non-woven fabric, activated carbon, photocatalyst, catalytic decomposition and electronic filter element, etc.

[0234] In other embodiments, when an ash collection support 8 is provided, the filter element support 32 can be connected to the bottom of the ash collection support 8. For example, the bottom of the filter element support 32 is hollowed out to avoid obstructing the flow of air, so that the filtered air can flow out smoothly.

[0235] In some embodiments, the bottom 24 of the housing 5 is smaller than the top of the housing 5 in the radial direction. For example, the housing 5 is cylindrical, with the lower diameter smaller than the upper diameter. When the ashtray 100 is used as a vehicle-mounted product in a car, it facilitates placement of the ashtray 100 in the cup holder, ensuring stable placement and preventing tipping. In this case, the air outlet 51 is located in the portion of the housing 5 with a relatively larger diameter to prevent it from being blocked by the cup holder after the ashtray 100 is placed in it, ensuring smooth airflow.

[0236] The ashtray 100 further includes at least one of the following: a power supply 71, located within the housing 5, which at least powers the fan assembly 4. The power supply 71 can also power other electrical components located within the ashtray 100.

[0237] The power source 71 can be a rechargeable battery (also known as a secondary battery). The ashtray 100 may also include a charging port 77. The charging port 77 is used to charge the power source 71. The charging port 77 can be a wireless charging port or a wired charging port. The wired charging port can be a USB port or a Type-C port, etc.

[0238] The ashtray 100 may also include a power supply bracket 72, which is located inside and connected to the housing 5. The power supply bracket 72 is used to mount the power supply 71 to prevent the power supply 71 from shaking.

[0239] The ashtray 100 may also include a main control board 73 and a board support 74 located within the housing 5. The board support 71 supports the main control board 73. The board support 74 is connected to the housing 5 or to the power supply support 72. The main control board 73 controls the electrical components within the ashtray 100, such as the opening and closing of the fan assembly 4, the power supply status of the power supply 71, and the operating status of the status detection components.

[0240] The ashtray 100 may also include an indicator light 76, which is disposed in the housing 5. The indicator light 76 can be used to indicate the remaining power status of the power supply 71, the charging status of the power supply 71, etc. For example, when the remaining power of the power supply 71 is lower than a set power level, the indicator light 76 is red. When the power supply 71 is charging, the indicator light 76 can display green and flash; when the power supply 71 is fully charged, the indicator light 76 displays solid green.

[0241] The ashtray 100 may also include a gasket 78, which may be disposed at the bottom of the housing 5. The gasket 78 provides anti-slip properties and improves the stability of the ashtray 100 when placed.

[0242] The ashtray 100 may also include a negative ion generator, disposed within the housing 5, downstream of the first air inlet 21. The negative ion generator produces negative ions to increase the amount of negative ions in the air flowing through the ashtray 100. These negative ions can combine with aerosol particles and odor molecules in the air, causing them to settle and reducing the concentration of aerosol particles, thus improving air purification.

[0243] The ashtray 100 may also include a water ion generator, which is disposed inside the housing 5 to generate water ions. It is located downstream of the first air inlet 21. The water ion generator can improve air purification efficiency.

[0244] The ashtray 100 may also include an aromatherapy component, which is disposed within the housing 5, downstream of the filter component 3 and upstream of the air outlet 51. The aroma released by the aromatherapy component can purify the air.

[0245] It should be noted that the upstream and downstream in this application are based on the direction of air flow. For example, if A is upstream of B, in other words, B is downstream of A, indicating that the air flows through A first and then through B.

[0246] It should be understood that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article indicates that the preceding and following related objects have an "or" relationship.

[0247] In the embodiments of this application, "multiple" refers to two or more.

[0248] The descriptions of "first," "second," etc., appearing in the embodiments of this application are for illustrative purposes and to distinguish the objects being described. They have no order and do not indicate any special limitation on the number of devices in the embodiments of this application, nor do they constitute any limitation on the embodiments of this application.

[0249] While this application discloses the above information, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of this application; therefore, the scope of protection of this application shall be determined by the scope defined in the claims.
