Description

Technical Field

[0001] This utility model relates to the field of electronic atomization, and in particular to a smoke filtration system. Background Technology

[0002] There are many types of electronic atomizers on the market. Those that heat and atomize diluted e-liquid for users to inhale do not offer a truly original and pure taste; while atomized products made from tobacco paste can provide users with an original and pure taste, thus becoming the choice of more users.

[0003] The smoke from tobacco paste is quite pungent. Many tobacco paste-based atomizing products mimic traditional hookah by placing a water tank under the tobacco paste heater. The smoke is guided into the water tank, filtered through the water, and then inhaled through the mouthpiece. However, this method requires a large water tank with a sufficient water volume, resulting in a bulky product. Furthermore, the water tank is typically made of glass, making it inconvenient to carry and fragile. Therefore, an improved solution is urgently needed. Utility Model Content

[0004] The purpose of this invention is to provide an effective smoke filtration system that is smaller and more portable than traditional kettle filter products.

[0005] To achieve the above objectives, the technical solution provided by this utility model is to provide a smoke filtration system, including a filter chamber, a filter liquid stored in the filter chamber, a filter cotton assembly stored in the filter chamber, and a heat-insulating and gas-dissipating layer; the filter chamber has a smoke inlet and a smoke outlet, the smoke inlet is used to receive the smoke to be filtered, and the smoke outlet is used to output the filtered smoke; the filter cotton assembly includes a liquid-retaining cotton, which is used to absorb the filter liquid; the heat-insulating and gas-dissipating layer is disposed on the side of the liquid-retaining cotton near the smoke inlet.

[0006] As a preferred technical solution, the filter cotton assembly further includes a first dry cotton block, which is disposed on the side of the liquid storage cotton near the flue gas outlet.

[0007] As a preferred technical solution, a porous partition is provided between the liquid storage cotton and the first dry cotton block.

[0008] As a preferred technical solution, the heat insulation and ventilation layer is provided with a plurality of ventilation holes that penetrate the heat insulation and ventilation layer, and the flue gas to be filtered can pass through the ventilation holes and enter the filter chamber.

[0009] As a preferred technical solution, the heat insulation and air dissipation layer is provided with a plurality of sinks on the side near the liquid storage cotton and a plurality of protrusions are provided between the plurality of sinks, and the plurality of air vents are dispersedly provided in the sinks and / or the protrusions; the protrusions support the liquid storage cotton.

[0010] As a preferred technical solution, the heat insulation and air dissipation layer has a recessed diffusion cavity on the side near the atomizer, and the diffusion cavity is connected to the plurality of air vents.

[0011] As a preferred technical solution, the filter chamber includes an upper sealing cover and a lower sealing cover; the heat insulation and gas dissipation layer is sleeved on the lower sealing cover; and the flue gas inlet is located on the lower sealing cover.

[0012] As a preferred technical solution, the flue gas inlet is located at the lower sealing cover; the lower sealing cover is provided with a receiving groove at the flue gas inlet, and the heat insulation and gas dissipation layer is placed in the receiving groove.

[0013] As a preferred technical solution, the thickness of the liquid storage cotton is greater than the thickness of the first dry cotton block; the pore size of the liquid storage cotton is greater than the pore size of the first dry cotton block.

This reduces the volume of the filter chamber, making the overall product smaller and easier to carry. Furthermore, by setting up a heat-insulating and gas-dissipating layer, the high temperature of the smoke from the atomizer prevents the liquid storage cotton from being damaged, thus ensuring the filtering effect on impurities in the smoke from the atomizer.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1 and Figure 2 This utility model provides a portable atomizing device 200, including a mouthpiece assembly 10, an atomizer 20, a battery assembly 30, and a smoke filtration system 50. The battery assembly 30 powers the atomizer 20. The atomizer 20 generates smoke; the smoke generated by the atomizer 20 passes through the smoke filtration system 50 and finally flows into the mouthpiece assembly 10. In this embodiment, the mouthpiece assembly 10, the smoke filtration system 50, the atomizer 20, and the battery assembly 30 are sequentially connected along the axial direction of the atomizing device 200.

[0019] The smoke filtration system 50 is interconnected with the atomizer 20, and the smoke filtration system 50 is used to reduce the harshness of the smoke from the atomizer 20. Please refer to... Figure 3 , Figure 4 and Figure 5 The smoke filtration system 50 has a smoke inlet 51 at one end connected to the atomizer 20, which receives the smoke to be filtered flowing out of the smoke passage of the atomizer 20. The smoke filtration system 50 also has a smoke outlet 59 at the other end connected to the mouthpiece assembly 10; the smoke outlet 59 outputs filtered smoke from the smoke filtration system 50. In this embodiment, the smoke outlet 59 is used to output filtered smoke to the mouthpiece assembly 10.

[0020] Please refer to Figure 3 and Figure 4The smoke filtration system 50 includes a filter chamber 52 and a filtrate stored in the filter chamber 52; the filtrate is generally water. Smoke flows into the filter chamber 52 from the smoke inlet 51. Since traditional hookahs only use water to filter smoke, a large amount of water is needed to reduce the harshness of the smoke; therefore, the filter chamber 52 needs to have a large volume, resulting in a relatively large overall size of the atomizing device, making it inconvenient to carry. In this embodiment, the smoke filtration system 50 includes a filter cotton assembly; the filter cotton assembly includes a liquid storage cotton 53. By using the liquid storage cotton 53 to absorb the filtrate, sufficient filtrate to filter the harshness can be stored in the smaller volume of the liquid storage cotton 53, thereby greatly reducing the volume of the filter chamber 52, thus reducing the overall size of the atomizing device and making the atomizing device portable.

[0021] Further, please refer to, 2. Figure 3 and Figure 4 The filter cotton assembly also includes a first dry cotton block 54. The first dry cotton block 54 is positioned above the liquid-retaining cotton 53 and at one end of the filter chamber 52 near the nozzle assembly 10; or, in other words, the first dry cotton block 54 is positioned on the side near the smoke outlet 59. That is, after the smoke passes through the liquid-retaining cotton 53, it flows to the first dry cotton block 54. The first dry cotton block 54 can absorb the moisture carried out by the smoke from the liquid-retaining cotton 53, and can prevent liquid splatter when the suction is strong; it also further filters impurities in the smoke to reduce pungent odor.

[0022] Preferably, to prevent the filtrate in the liquid-retaining cotton 53 from being siphoned by the first dry cotton block 54, a porous partition 55 is provided between the liquid-retaining cotton 53 and the first dry cotton block 54. The porous partition 55 is used to block the filtrate from entering the first dry cotton block 54 and to guide the smoke passing through the liquid-retaining cotton 53 to flow to the first dry cotton block 54. More preferably, the first dry cotton block 54 covers the entire contact surface of the porous partition 55 to prevent the smoke from flowing directly to the mouthpiece 11 without passing through the first dry cotton block 54. Understandably, the thickness of the liquid-retaining cotton 53 is greater than the thickness of the first dry cotton block 54 to absorb more filtrate and extend the filtration path of the smoke. In a preferred embodiment, the thickness ratio of the liquid-retaining cotton 53 to the thickness of the first dry cotton block 54 is 3:1. More preferably, the pore size of the liquid-retaining cotton 53 is larger than the pore size of the first dry cotton block 54. The liquid-storing cotton 53 has a high-porosity open-cell structure, while the first dry cotton block 54 has a low-porosity dense structure. This allows the liquid-storing cotton 53 to absorb a large amount of filtrate, and even after absorbing sufficient filtrate, it still retains enough pores for smoke to pass through. The first dry cotton block 54 only needs pores large enough for smoke to pass through; furthermore, smaller pores in the first dry cotton block 54 better reduce the moisture content of the smoke and further absorb pungent odors.

[0023] Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7In this embodiment, the smoke filtration system 50 further includes a heat-insulating and gas-dispersing layer 56 disposed below the liquid storage cotton 53. Specifically, the heat-insulating and gas-dispersing layer 56 is disposed on the side of the liquid storage cotton 53 near the smoke inlet 51. After the smoke from the atomizer 20 flows in from the smoke inlet 51, it is dispersed to the contact surface of the liquid storage cotton 53 by the heat-insulating and gas-dispersing layer 56 in the filter chamber 52. In this way, the high temperature of the smoke from the atomizer 20 can prevent the liquid storage cotton 53 from being scalded by the smoke.

[0024] Specifically, please refer to Figure 6 The heat insulation and ventilation layer 56 is provided with a plurality of vents 562 penetrating the heat insulation and ventilation layer 56, allowing the smoke from the atomizer 20 to pass through the vents 562 and enter the filter chamber 52. A plurality of grooves 561 are provided at one end of the heat insulation and ventilation layer 56 near the liquid storage cotton 53. A plurality of spaced protrusions are provided between the grooves 561 to form a grid-like structure 563. The protrusions support the liquid storage cotton 53. The vents 562 are dispersedly arranged in the grooves 561 and / or the protrusions 563. Preferably, please refer to... Figure 7 The heat insulation and gas dissipation layer 56 has a recessed diffusion cavity 565 on the side near the atomizer 20, and the diffusion cavity 565 is connected to several vent holes 562. In this way, the smoke from the atomizer 20 is diffused and enters the filter cavity 52 through the vent holes 562, and the smoke is further dispersed by the grid-like arrangement 563; so that the smoke can be dispersed to the contact surface of the liquid storage cotton 53 and flow evenly through the liquid storage cotton 53; thus increasing the deodorizing effect of the smoke.

[0025] Preferably, the filter chamber 52 includes an upper sealing cover 52A and a lower sealing cover 52B. See also... Figure 3 , Figure 4 and Figure 5 In this embodiment, the upper sealing cap 52A and the lower sealing cap 52B are closed to form a filter chamber 52. A heat-insulating and venting layer 56 is fitted onto the lower sealing cap 52B, and the outer wall of the heat-insulating and venting layer 56 is provided with several annular sealing teeth 52C along its axial direction. After assembly, the several annular sealing teeth 52C are in close contact with the inner wall of the upper sealing cap 52A to prevent leakage of the filtrate. Furthermore, a liquid storage space is formed between two adjacent sealing teeth 52C to store leaked filtrate; several liquid storage spaces are formed between the several annular sealing teeth 52C. In practical applications, leaked filtrate will first flow to the first liquid storage space, with the liquid storage space closest to the liquid storage cotton 53 being the first liquid storage space. After the first liquid storage space is full, it overflows and flows to the next liquid storage space. When the liquid storage cotton 53 has been used for a long time and contains less filtrate, some filtrate can diffuse from the liquid storage space into the liquid storage cotton 53, thereby extending the service life of the liquid storage cotton 53. Please refer to [link to relevant documentation]. Figure 4 and Figure 5 The smoke inlet 51 of the smoke filtration system 50 is located at the lower sealing cover 52B.

[0026] Understandably, a plurality of annular sealing teeth 52C are axially arranged on the upper sealing cover 52A or the lower sealing cover 52B; or the filter cavity 52 further includes a cavity sleeve with openings at both ends, with the upper sealing cover 52A and the lower sealing cover 52B respectively covering the openings at both ends of the cavity sleeve; the outer peripheral walls of the upper sealing cover 52A and the lower sealing cover 52B each have a plurality of annular sealing teeth 52C spaced apart along their axial direction. In this embodiment, the lower sealing cover 52B is provided with a receiving groove at the flue gas inlet 51, and the heat insulation and gas dissipation layer 56 is placed in the receiving groove.

[0027] In another embodiment, the smoke filtration system 50 is further provided with an atomizing element (not shown in the schematic diagram) for atomizing the filter liquid, so that the atomized filter liquid mixes with the smoke generated by the atomizer 20. In this way, the atomized filter liquid can adsorb impurities in the smoke, reducing the pungent taste. Preferably, the liquid storage cotton 53 covers the atomizing element of the filter liquid to ensure that the atomizing element of the filter liquid is in contact with the filter liquid. In this case, the power supply electrode 35 has at least two sets, one set of which is electrically connected to the heating element of the atomizer 20; the other set of which is electrically connected to the atomizing element for atomizing the filter liquid.

[0028] Further, please refer to Figure 8 and Figure 9 The portable atomizing device 200 also includes an air guiding assembly 60; the air guiding assembly 60 includes an air guiding element 61 and a second dry cotton pad 62. The air guiding element 61 is provided with a channel 63 for guiding the first smoke passage of the smoke filtration system 50; the second dry cotton pad 62 is disposed on the side of the air guiding element 61 near the first dry cotton block 54, preferably, the second dry cotton pad 62 covers the area around the outer periphery of the channel. After the smoke flows out from the first dry cotton block 54, the second dry cotton pad 62 further adsorbs the liquid carried out by the smoke from the liquid storage cotton and adsorbs the condensate in the smoke, and then flows to the mouthpiece assembly 10 through the channel 63. In this embodiment, the air guiding assembly 60 and the smoke filtration system 50 are integrated into a single housing. It can be understood that the air guiding assembly 60 can also be integrated into the mouthpiece assembly 10.

[0029] The above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, such as combining different features in various embodiments, and these all fall within the protection scope of the present invention.
