Description

Technical Field

[0001] The present disclosure generally relates to hookah smoking devices, and more particularly to a system for purifying the smoke generated during the smoking process of a hookah smoking device. Background Art

[0002] Worldwide, the consumption of tobacco products (such as tobacco leaves) and other plant products and their derivatives is a long-standing tradition. For a long time, various different devices have been manufactured to facilitate the consumption of such products. These devices include rolled tobacco leaves (such as tobacco leaves rolled in paper), pipes, and hookahs.

[0003] The hookah (also known as a water pipe, water tube, narghile, and shisha) originated in countries such as India and Pakistan decades ago, and then became popular in Middle Eastern countries and gradually spread to other regions of the world. After continuous structural optimization, the hookah has formed various differentiated design types, and the related product system has been widely used globally. However, the basic structural principle of the hookah has always remained unchanged. Tobacco leaves or flavored tobacco are placed in a combustion chamber for combustion treatment. The combustion chamber contains tobacco leaves, and combustion charcoal blocks are placed on top of the tobacco leaves. A through hole is provided at the bottom of the combustion chamber, which is connected to an air duct through a conduit. The air duct is further connected to a water container. The amount of water contained in the water container reaches one-half or less of its volume. A guiding channel for connecting a hose and a mouthpiece is provided in the air duct. When the user inhales through the mouthpiece and the hose, the smoke generated by the burning tobacco leaves in the combustion chamber is conducted to the water container under the action of negative pressure through the air duct. The smoke then passes through the water stored in the water container in the form of bubbles, is conducted to the hose through the guiding channel in the air duct, and finally enters the smoker's mouth and respiratory system.

[0004] Although the design purpose of bubbling the smoke through the water in the water container is to achieve the smoke filtering function, after the smoke generated by burning tobacco passes through the water bubbling treatment, the damaging components generated by the combustion of the tobacco contained therein cannot be effectively filtered or reduced. The core function of bubbling the smoke through the water is to cool the smoke, but in essence, it fails to effectively filter or eliminate the toxic substances in the tobacco smoke. The traditional hookah cannot effectively filter the tar, ash, and toxic chemical components (such as hydrogen cyanide, formaldehyde, ammonia, and toxic free radicals) in the smoke. Therefore, most of the damaging components in the smoke enter the smoker's body unhindered, thereby causing harm to the smoker's health.

[0005] Certain solutions are known in the prior art which provide a filter attachable to the outlet of a hose near the smoker's mouth. These filters (also known as "mouth-end filters") are designed to filter physical impurities and absorb some of the tar or chemicals generated during the tobacco combustion process. In addition, certain cigarette holders employ cotton or carbonaceous filter elements to cool and filter the smoke as it passes through. Further, some other devices utilize a silica gel system in place of the carbonaceous or cotton filter elements. However, due to the relatively small cross-sectional area of those devices typically attached to the end of a hookah hose, the user (i.e., the smoker) experiences a significant increase in resistance when an additional mouth-end filter is added to the end of the hookah hose. The smoker will have to draw more forcefully and create an additional pressure gradient to overcome the additional resistance created by the filter. Additionally, these conventional filters are unable to significantly attenuate the gaseous toxins present in the mainstream smoke generated by hookahs. As previously mentioned, these gaseous toxins include hydrogen cyanide, formaldehyde, ammonia, and other chemicals. The currently available filters fail to effectively reduce the user's exposure to the toxic free radicals generated during the tobacco combustion process.

[0006] Accordingly, there is a need for an efficient and low-resistance filtration solution that can attenuate the particulate and gaseous components generated during the tobacco combustion process. Summary of the Invention

[0007] In accordance with various aspects shown herein, a system for purifying the smoke generated during the consumption of a hookah smoking device is disclosed. The system may include a first filter configured to be installed below a tobacco bowl, the tobacco bowl being vertically above the water level of the water contained in the base of the hookah smoking device. The first filter may include a first layer of cellulose acetate filter paper, a second layer of cellulose acetate filter paper, and an additive layer sandwiched between the first layer of cellulose acetate filter paper and the second layer of cellulose acetate filter paper. In response to an inhalation action, smoke is drawn from the tobacco bowl through the first filter into the base. The system may further include a second filter configured to be vertically below the first filter and vertically above the water level of the water contained in the base. The second filter may include a first layer of cellulose acetate filter paper, a second layer of cellulose acetate filter paper, and an additive layer sandwiched between the first layer of cellulose acetate filter paper and the second layer of cellulose acetate filter paper. In response to the inhalation action, the smoke is received into the base after bypassing the second filter, generating bubbled smoke by bubbling through the water in the base, and the bubbled smoke is drawn from the base through the second filter.

[0008] According to other aspects shown herein, a hookah smoking device is disclosed. The hookah smoking device may include a smoke bottle configured to store water and a smoke bowl vertically located above the smoke bottle, wherein a smoking product is burned in the smoke bowl to generate smoke. The hookah smoking device may further include a stem connecting the smoke bottle and the smoke bowl, and a first filter mounted below the smoke bowl and vertically above the water level of the water contained in the smoke bottle. The first filter may include a first layer of cellulose acetate filter paper, a second layer of cellulose acetate filter paper, and an additive layer sandwiched between the first layer of cellulose acetate filter paper and the second layer of cellulose acetate filter paper. In response to an inhalation action, the smoke is sucked from the smoke bowl through the first filter into the smoke bottle. The hookah smoking device may further include a second filter mounted and vertically located below the first filter and vertically above the water level of the water contained in the smoke bottle. The second filter may include a first layer of cellulose acetate filter paper, a second layer of cellulose acetate filter paper, and an additive layer sandwiched between the first layer of cellulose acetate filter paper and the second layer of cellulose acetate filter paper. In response to the inhalation action, the smoke bypasses the second filter and is received into the smoke bottle, generating bubbled smoke by bubbling in the water of the smoke bottle; thereafter, the bubbled smoke is sucked from the smoke bottle through the second filter.

[0009] According to other aspects shown herein, another system for purifying smoke generated during the smoking process of a hookah smoking device is disclosed. The system may include a first filter configured to be mounted below a smoke bowl, the smoke bowl being vertically located above the water level of the water contained in the smoke bottle of the hookah smoking device. The first filter may include a first layer of cellulose acetate filter paper, a second layer of cellulose acetate filter paper, and an additive layer sandwiched between the first layer of cellulose acetate filter paper and the second layer of cellulose acetate filter paper. In response to an inhalation action: the smoke is sucked from the smoke bowl through the first filter into the smoke bottle; the smoke is received into the smoke bottle, generating bubbled smoke by bubbling in the water of the smoke bottle; thereafter, the bubbled smoke is sucked and discharged from the smoke bottle.

[0010] According to other aspects shown herein, another system for purifying smoke generated during the smoking process of a hookah smoking device is disclosed. The system may include a filter configured to be mounted and vertically located above the water level of the water contained in the smoke bottle of the hookah smoking device. The filter may include a first layer of cellulose acetate filter paper, a second layer of cellulose acetate filter paper, and an additive layer sandwiched between the first layer of cellulose acetate filter paper and the second layer of cellulose acetate filter paper. In response to an inhalation action, the smoke is sucked from the smoke bowl into the smoke bottle, bypasses the filter, and generates bubbled smoke by bubbling in the water of the smoke bottle; thereafter, the bubbled smoke is sucked from the smoke bottle through the filter.

DETAILED DESCRIPTION

[0020] The following detailed description is described in conjunction with the accompanying drawings. Certain embodiments described are intended to illustrate the present disclosure, not to limit its scope, which is defined by the claims. Those of ordinary skill in the art will recognize that there are several equivalent variations in the following description.

[0021] The present invention discloses a system for purifying the smoke generated during the smoking process of a hookah smoking device. The purpose of this system is to provide a comprehensive solution to weaken and significantly reduce the exposure to toxic substances generated by the hookah smoking device (i.e., the hookah, Hookah). During the operation of the hookah smoking device, charcoal and tobacco leaves are burned. Due to the burning of charcoal and tobacco leaves, particulate matter, toxins, tar, and other physical toxins are generated. The system described in this disclosure removes the particulate matter, toxins, tar, and other physical toxins from the smoke that is ultimately inhaled by the user (i.e., the smoker) through filtration.

[0022] The system may include a first filter (also known as the "bowl filter"), which may comprise two layers of cellulose acetate or similar materials. The two layers of cellulose acetate (or similar materials) can filter and capture toxins, tar, and other physical toxins in the smoke. The first filter may also include an intermediate layer, which may comprise cellulose, plastic beads, or activated carbon antioxidant particles or beads, and the intermediate layer will capture hydrogen cyanide, formaldehyde, and ammonia. The intermediate layer composed of the antioxidant particles or beads can remove a significant proportion of the toxic free radicals generated during the combustion of tobacco.

[0023] The system may further include a second filter (also known as the "bottle filter") similar to the first filter. The first filter is disposed between the bottom of the tobacco bowl (i.e., the place where tobacco is burned) and the head of the stem, while the second filter is disposed at the neck of the bottle of the hookah smoking device (i.e., between the bottom of the stem and the top of the bottle). Compared with the conventionally known filters, the large cross-sectional area of the first filter and the second filter results in extremely low suction resistance of the hookah smoking device. Therefore, users will not be resistant to using the filters (i.e., the first filter and the second filter) because only a minimal additional negative pressure is required to inhale the smoke through the filters.

[0024] The first filter is in a double-cone shape. The upper part of the first filter includes a female connector, which will be connected to and firmly snap-connected to the bottom of the tobacco bowl. The lower part of the first filter is a male connector, which will be firmly snap-connected to the head of the stem of the hookah smoking device. The intermediate chamber of the first filter houses the two layers of cellulose acetate filter paper and the intermediate layer composed of activated carbon and antioxidant particles. To install the system on the hookah smoking device, the user can insert the male end (i.e., the bottom) of the tobacco bowl into the female connector of the first filter. Subsequently, the first filter is firmly installed onto the head of the stem. The female connector and the male connector may include a conical sealing structure, which forms a tight seal between the first filter and the bottom of the tobacco bowl and the stem, thus constituting a closed system.

[0025] The second filter is a cylindrical filter configured to be mounted and firmly fixed to the neck of the smoke bottle and vertically above the water level in the smoke bottle. The smoke inhaled by the user must pass through the second filter before reaching the mouth. Additionally, the second filter may include a first annular porous membrane and a second annular porous membrane, which are located near the top and bottom of the second filter respectively. The two annular porous membranes (i.e., the first annular porous membrane and the second annular porous membrane) allow the smoke to pass through freely.

[0026] Figure 1 FIG. schematically illustrates a hookah smoking device 100 configured with a system 110 for purifying smoke during inhalation from the hookah smoking device 100, according to some embodiments. As described above, the hookah smoking device 100 (also known as a hookah, shisha, etc. in different parts of the world) can be used to inhale smoke / vapor generated by the combustion of various plant-derived products (such as tobacco).

[0027] It should be noted that the system 110 can be retrofitted to a traditional hookah smoking device. As Figure 1 shown and understood by those skilled in the art, the traditional hookah smoking device 100 may include a smoke bottle 102 near the bottom of the hookah smoking device 100, a smoke bowl 104 near the top of the hookah smoking device 100, and a slender stem tube 106 connecting the smoke bottle 102 and the smoke bowl 104. The smoke bowl 104 can be used to burn tobacco products and charcoal particles. The stem tube 106 of the hookah smoking device 100 may define a slender inner conduit 106A extending along the length of the stem tube 106. As Figure 1 shown, the smoke bowl 104 can be located at the top of the hookah smoking device 100 for easy replenishment during the consumption of tobacco products.

[0028] As Figure 1 shown, in some exemplary embodiments, the hookah smoking device 100 may further include a tray 116 located below the smoke bowl 104. The tray 116 is configured to receive and store the burned charcoal and tobacco particles that fall from the smoke bowl 104. Thus, the tray 116 can prevent the burned charcoal and tobacco particles from falling to the ground, damaging the hookah smoking device 100, or coming into contact with the user. The tray 116 can be a circular tray with a central hole in the middle, such that the tray 116 can be mounted on the stem tube 106 of the hookah smoking device 100.

[0029] The cigarette bottle 102 may be a sealed container for storing water (or other liquids, such as flavored liquids). The cigarette bottle 102 is in fluid communication with the cigarette bowl 104 through the conduit 106A of the elongated stem tube 106. The smoke generated by the burning of the tobacco product in the cigarette bowl 104 is received into the cigarette bottle through the conduit 106A of the stem tube 106. The flow (F) of the smoke is Figure 1 Indicated by the middle arrow. In response to the inhalation action of the user (i.e., the smoker), a negative pressure is formed in the cigarette bottle 102, so that the smoke is sucked into the cigarette bottle 102. The top end of the conduit 106A is connected to the cigarette bowl 104 (to receive the smoke), and the bottom end of the conduit 106A is immersed in the water in the cigarette bottle 102 (i.e., the bottom end of the conduit 106A is located below the water level). When the smoke is received and bubbles in the water in the cigarette bottle 102, bubbled smoke is generated. It should be noted that the term "bubbled smoke" refers to the state of the smoke after bubbling in the water in the cigarette bottle. It is understandable that the user can then inhale the bubbled smoke by sucking from the cigarette bottle 102.

[0030] The lower end of the stem tube 106 may define a steam chamber 118. The bubbling smoke may be received and accumulated in the steam chamber 118 of the stem tube 106. Subsequently, the bubbling smoke is drawn from the steam chamber 118 and inhaled by the user, as shown by flow (F).

[0031] The cigarette bottle 102 may define an upper end 102A, through which the cigarette bottle 102 is connected to the stem tube 106. In other words, the cigarette bottle 102 may define the upper end 102A, which serves as an interface between the cigarette bottle 102 and the stem tube 106. The cigarette bottle 102 may contain water up to a certain water level, so that the water level is maintained below the upper end 102A of the cigarette bottle 102. The hookah smoking device 100 may also include a straw 108, which is connected to the cigarette bottle 102 in fluid communication to transport the bubbling smoke outward from the cigarette bottle 102.

[0032] like Figure 1 As shown, the distal end of the straw 108 can be disposed in the steam chamber 118. Therefore, the user can draw and inhale the bubbling smoke from the steam chamber 118 of the stem tube 106 through the proximal end of the straw 108. The distal end of the straw 108 is thus located above the water level of the cigarette bottle 102.

[0033] The stem tube 106 of the hookah smoking device 100 may further include an exhaust valve 120, for example, disposed at the steam chamber 118 of the stem tube 106. The exhaust valve 120 may be used to release excess post-bubbling smoke accumulated in the steam chamber 118 of the stem tube 106.

[0034] To purify the smoke after bubbling (also referred to as "vapor" in this disclosure), the hookah smoking device 100 may be configured with a system 110 as shown in Figure 1 FIG. 1. In some embodiments, the system 110 may include a first filter 112 and a second filter 114. The first filter 112 is configured to be installed below the tobacco bowl 104. Thus, the first filter 112 is vertically above the water level of the water contained in the water bottle 102 of the hookah smoking device 100. Specifically, the first filter 112 is disposed directly below the tobacco bowl 104 and adjacent to the top region of the stem 106. The second filter 114 is configured to be installed and vertically below the first filter 112, while being vertically above the water level of the water contained in the water bottle 102. In other words, the second filter 114 is disposed in the bottom region of the stem 106 and above the water bottle 102 (or in the top region of the water bottle 102).

[0035] When the smoker inhales the smoke after bubbling, in response to this inhalation action, a negative pressure is formed in the water bottle 102, causing the smoke to be suctioned from the tobacco bowl 104 through the first filter 112 into the water bottle 102. Thus, when the smoke from the tobacco bowl 104 passes through the first filter 112, the first filtration process is completed in the first filter 112. Further, in response to the inhalation action, the smoke bypasses the second filter 114 and is received into the water bottle 102. Once the smoke enters the water bottle 102, it bubbles in the water in the water bottle to form the smoke after bubbling. Subsequently, the user sucks the smoke after bubbling from the water bottle 102 by passing the smoke after bubbling through the second filter 114. Thus, when the smoke after bubbling from the water bottle 102 passes through the second filter 114, the second filtration process is completed in the second filter 114. The user can suck and inhale the smoke after bubbling from the vapor chamber 118 of the stem 106 through the proximal end of the straw 108. The distal end of the straw 108 is thus disposed above the water level of the water bottle 102.

[0036] The stem 106 of the hookah smoking device 100 may further include an evacuation valve 120, such as disposed at the vapor chamber 118 of the stem 106. The evacuation valve 120 can be used to release the excessive accumulated smoke after bubbling in the vapor chamber 118 of the stem 106. The first filter 112 and the second filter 114 will be described in detail in conjunction with Figure 2-3 FIG. 2.

[0037] Figure 2The diagram shows a schematic front view of the first filter 112. According to some embodiments, the first filter 112 may include a first layer 202 of acetate filter paper and a second layer 204 of acetate filter paper. The first filter 112 may also include an additive layer 206 sandwiched between the first layer 202 and the second layer 204. In some embodiments, the additive may include activated carbon particles saturated with an antioxidant.

[0038] The first filter 112 can be configured to be installed on the upper portion of the stem tube 106 of the hookah smoking device 100. Figure 1 As shown. In addition, the first filter 112 may be cylindrical. Specifically, the first filter 112 may be biconical. Therefore, the first filter 112 may define a first conical portion 208 toward its upper side and a second conical portion 210 toward its lower side. The shape and size of the second conical portion 210 may be similar to the first conical portion 208, but the orientation of the second conical portion 210 is opposite to that of the first conical portion 208 (i.e., upside down). The first filter 112 may also define an intermediate chamber 212 between the first conical portion 208 and the second conical portion 210. The acetate filter paper of the first layer 202, the acetate filter paper of the second layer 204, and the additive layer 206 may be disposed in the intermediate chamber 212 of the first filter 112.

[0039] The first filter 112 may further include a female connector 214 located on the top side thereof. The female connector 214 is configured to receive the base of the cigarette bowl 104 so that the base of the cigarette bowl 104 can be snapped into the female connector 214. Figure 2 As shown, the cigarette bowl 104 is generally defined as a tapered structure that tapers downward, with a wider top and a narrower bottom. The female connector 214 may also define a similar tapered structure, so that the base of the cigarette bowl 104 can be received into the female connector 214. Thus, the base of the cigarette bowl 104 can be press-fitted into the female connector 214 of the first filter 112.

[0040] The first filter 112 may further include a male connector 216 located at the bottom side thereof. The male connector 216 is configured to snap into the head of the stem tube 106. Figure 1 As shown, the head of the stem tube 106 is generally defined as a tapered structure that tapers upward, being narrower at the top and wider at the bottom. The male connector 216 may also define a similar tapered structure, so that the bottom of the male connector 216 can be received into the head of the stem tube 106. Thus, the male connector 216 can be press-fitted into the head of the stem tube 106 of the hookah smoking device 100.

[0041] like Figure 2As shown, the intermediate chamber 212 can be disposed between the female connector 214 and the male connector 216. The intermediate chamber 212 can be configured to accommodate the cellulose acetate filter paper of the first layer 202, the cellulose acetate filter paper of the second layer 204, and the additive layer 206.

[0042] In some embodiments, the first filter 112 may further include a first porous membrane 218, which can be disposed between the female connector 214 and the intermediate chamber 212. In other words, the first porous membrane 218 can be disposed immediately above the cellulose acetate filter paper of the first layer 202. The first porous membrane 218 is configured to allow the smoke to pass through freely. The first filter 112 may further include a second porous membrane 220, which can be disposed between the intermediate chamber 212 and the male connector 216. In other words, the second porous membrane 220 can be disposed immediately below the cellulose acetate filter paper of the second layer 204. The second porous membrane 220 is also configured to allow the smoke to pass through freely.

[0043] Therefore, the first filter 112 is configured to filter the smoke generated by the combustion of the tobacco product in the tobacco bowl 104 when the smoke passes through the first filter 112 and enters the stem 106. The smoke sequentially passes through the cellulose acetate filter paper of the first layer 202, the cellulose acetate filter paper of the second layer 204, and the additive layer 206.

[0044] Figure 3 A schematic front view of the second filter 114 is illustrated, according to some embodiments. The second filter 114 may include a cellulose acetate filter paper of a first layer 302 and a cellulose acetate filter paper of a second layer 304. The second filter 114 may further include an additive layer 306 sandwiched between the first layer 302 and the second layer 304. In some embodiments, the additive may include activated carbon particles saturated with an antioxidant. As Figure 1 shown, the second filter 114 is configured to be installed in the bottom region of the stem 106 of the hookah smoking device 100 and adjacent to the top of the smoke bottle 102.

[0045] As Figure 3As shown, the second filter 114 may be cylindrical. In some embodiments, the second filter 114 may define an upper end 308 and a lower end 310. The second filter 114 is joined to the lower portion of the stem 106 through the upper end 308, thereby mounting the second filter 114 to the stem 106. In addition, the second filter 114 is joined to the upper end (i.e., the head) of the smoke bottle 102 through the lower end 310, thereby mounting the second filter 114 to the smoke bottle 102. Therefore, the upper end 308 of the second filter 114 may be mounted to the lower portion of the stem 106 of the hookah 100, and the lower end 310 of the second filter 114 may be mounted to the head of the smoke bottle 102 of the hookah 100. For this purpose, the second filter 114 may further include a first elastic band 312, which is configured to fix and seal the second filter 114 to the lower portion of the stem 106. In addition, the second filter 114 may include a second elastic band 314, which is configured to fix and seal the second filter 114 to the head of the smoke bottle 102.

[0046] As Figure 3 shown, the second filter 114 may define a hollow portion 316 in the middle thereof. In other words, the cellulose acetate filter paper of the first layer 302, the cellulose acetate filter paper of the second layer 304, and the additive layer 306 each define a hollow portion (collectively constituting the hollow portion 316). The hollow portion 316 is configured to accommodate the straw 108. As described above, the straw 108 is connected to the smoke bottle 102 for delivering the bubbled smoke from the smoke bottle 102.

[0047] In some embodiments, the second filter 114 may further include a first porous membrane 318, which may be disposed toward the upper end 308 of the second filter 114. In other words, the first porous membrane 318 may be disposed immediately above the cellulose acetate filter paper of the first layer 302. The first porous membrane 318 is configured to allow the bubbled smoke to pass through freely. As described above, the bubbled smoke is formed by the smoke generated in the tobacco bowl 104 bubbling in the water contained in the smoke bottle 102. The second filter 114 may further include a second porous membrane 320, which may be disposed toward the upper end 308 of the second filter 114. In other words, the second porous membrane 320 may be disposed immediately below the cellulose acetate filter paper of the second layer 304. The second porous membrane 320 is configured to allow the bubbled smoke to pass through freely.

[0048] Accordingly, the second filter 114 is configured to filter the post-bubble smoke generated by the smoke bubbling in the water bottle 102 when the post-bubble smoke passes through the second filter 114 and enters the stem 108. The post-bubble smoke sequentially passes through the cellulose acetate filter paper of the first layer 302, the cellulose acetate filter paper of the second layer 304, and the additive layer 306.

[0049] Figure 4 FIG. shows an enlarged view of a portion (A) of the hookah smoking device 100 configured with the system 110, according to an embodiment as shown. As Figure 1 shown. As Figure 4 shown, the distal end 402 of the straw 108 can be located within the vapor chamber 118 and above or inside the second filter 114. Accordingly, the distal end 402 of the straw 108 receives the post-bubble smoke from the water bottle 102, and the post-bubble smoke enters the straw 108 after being filtered by the second filter 114.

[0050] Figure 5 FIG. shows a flowchart of a method 500 for preparing the layer 206 of the first filter 112 and the layer 306 of the second filter 114, according to some embodiments. As described above, the additive layer 206 or 306 may include activated carbon particles saturated with an antioxidant.

[0051] In step 502, an antioxidant (the antioxidant may be water-soluble) can be dissolved in a solvent. For example, the antioxidant may be lycopene, and the solvent may be 95% ethanol. The amount of the solvent can be determined according to the solubility of the antioxidant in the solvent.

[0052] In step 504, cellulose or plastic beads with a small pore diameter and a low pore volume can be prepared. The small pore diameter and low pore volume can increase the surface area available for adsorbing chemical substances. In some embodiments, activated carbon in crystal form can be used. It can be understood that activated carbon is a carbon material treated to form a carbon material with a small pore diameter and a low pore volume, thereby increasing the surface area available for adsorbing chemical substances.

[0053] In step 506, lycopene (i.e., the antioxidant) can be coated onto the surface of the cellulose or plastic beads (or activated carbon beads) through a spraying process. Specifically, the activated carbon particles can be coated with lycopene through a spraying process. To this end, the particles can be placed in a container or drum, and a lycopene coating solution can be sprayed onto the particle surface through a nozzle. Subsequently, the coated particles are dried to remove the residual solvent and ensure that the lycopene coating adheres firmly to the particle surface. In some embodiments, detection techniques such as ultraviolet-visible spectroscopy, high-performance liquid chromatography, or mass spectrometry can be used to ensure that the particle surface is evenly coated and the coating has the desired antioxidant properties. The dosage of the antioxidant particles in the filter needs to be determined after experimental verification. Finally, the antioxidant particles are encapsulated between two thin layers of plastic acetate fiber, and other or additional fiber materials can be selected according to the final design of the filter.

[0054] In addition, in some embodiments, a fat-soluble antioxidant solution (such as pomegranate juice or syrup) can be poured into a large bowl or container (the amount of the solution depends on the number of beads to be coated). The cellulose or plastic beads are added to the bowl and stirred until the beads are completely covered by the antioxidant liquid (pomegranate juice or other antioxidant). A strainer or cheesecloth can be used to remove the excess liquid remaining on the coated beads. Subsequently, the coated beads are laid out in a single layer on a baking sheet or tray.

[0055] In step 508, after the beads are coated, they can be subjected to high-temperature treatment. To this end, the beads are placed on a baking sheet and the baking sheet is placed in a preheated oven and baked at a temperature of about 225°F (107°C) for about 2 hours until the beads are completely dry and brittle. To ensure uniform drying, the beads can be turned over regularly. Subsequently, the baking sheet is removed from the oven and the coated beads are allowed to cool completely. After removing the loose or excess coating, the coated activated carbon particles are transferred to a sealed container for storage.

[0056] The dosage of the antioxidant particles in each filter needs to be determined after necessary experimental verification. In the initial stage, 200 milligrams (mg) of antioxidant particles can be used for each filter. The antioxidant particles can be encapsulated between two thin layers of plastic acetate fiber. However, it should be noted that other or additional fiber materials can also be used.

[0057] Figure 6 Illustrated is a configuration with a filter 602 (corresponding to Figure 1Schematic diagram of a hookah smoking device 100 (the first filter therein), the filter being used to purify the smoke generated during the use of the hookah smoking device, according to some embodiments. The filter 602 can be retrofitted into a traditional hookah smoking device 100. As previously described, the traditional hookah smoking device 100 can include a smoke bottle 102 near its bottom, a smoke bowl 104 near its top, and a slender stem 106 connecting the smoke bottle 102 and the smoke bowl 104. The stem 106 defines a slender inner conduit 106A extending along its length. The smoke bowl 104 is located at the top of the hookah smoking device 100. The hookah smoking device 100 can also include a tray 116 below the smoke bowl 104 for collecting the burned charcoal and tobacco particles that fall from the smoke bowl 104. The smoke bottle 102 can store water (or other liquid, such as a flavoring liquid) and is in fluid communication with the smoke bowl 104 through the conduit 106A of the slender stem 106. Due to the suction action of the user (i.e., the smoker), a negative pressure is formed in the smoke bottle 102, and the smoke generated by the burning of the tobacco product in the smoke bowl 104 is inhaled into the smoke bottle through the conduit 106A of the stem 106. The top end of the conduit 106A is connected to the smoke bowl 104, and the bottom end is immersed in the water in the smoke bottle 102. When the smoke enters and mixes with the water in the smoke bottle 102, bubbling smoke is formed.

[0058] The smoke bottle 102 can define an upper end 102A through which the smoke bottle 102 is connected to the stem 106. In other words, the smoke bottle 102 can define the upper end 102A, which serves as an interface between the smoke bottle 102 and the stem 106. The smoke bottle 102 can hold water up to a certain water level such that the water level is maintained below the upper end 102A of the smoke bottle 102. The straw 108 is fluidly connected to the smoke bottle 102 to convey the bubbling smoke out of the smoke bottle 102. The distal end of the straw 108 is disposed within the steam chamber 118. Thus, the user can suck and inhale the bubbling smoke from the steam chamber 118 of the stem 106 through the proximal end of the straw 108. The stem 106 of the hookah smoking device 100 can also include an evacuation valve 120, for example, disposed at the steam chamber 118 of the stem 106. The evacuation valve 120 is used to release the excessive accumulation of bubbling smoke in the steam chamber 118 of the stem 106.

[0059] To purify the smoke, the hookah smoking device 100 can be configured as Figure 6 shown in the filter 602. The filter 602 is configured to be installed below the smoke bowl 104 and thus vertically above the water level of the water contained in the smoke bottle 102 of the hookah smoking device 100. Specifically, the filter 602 is disposed directly below the smoke bowl 104 and adjacent to the top region of the stem 106. The structure and function of the filter 602 have been combined with Figure 2has been described in detail.

[0060] When a smoker inhales the bubbled smoke, in response to the inhalation action, a negative pressure is formed inside the smoke bottle 102, causing the smoke to be sucked from the smoke bowl 104 through the filter 602 into the smoke bottle 102. Therefore, when the smoke from the smoke bowl 104 passes through the filter 602, the first filtration process is completed in the filter 602. Further, in response to the inhalation action, the smoke is received into the smoke bottle 102. Once the smoke enters the smoke bottle 102, it bubbles in the smoke bottle water to form bubbled smoke. Subsequently, the user sucks the bubbled smoke from the smoke bottle 102. The user can suck and inhale the bubbled smoke from the steam chamber 118 of the stem 106 through the proximal end of the straw 108. The distal end of the straw 108 is thus disposed above the water level in the smoke bottle 102.

[0061] Figure 7 illustrates a schematic diagram of a hookah smoking device 100 configured with a filter 702 (corresponding to Figure 1 the second filter in), which is used to purify the smoke generated during the use of the hookah smoking device, according to some embodiments. The filter 702 can be added to the traditional hookah smoking device 100. The structure and function of the traditional hookah smoking device 100 have been described in detail in combination with Figure 1 and Figure 6 has been described in detail.

[0062] To purify the smoke, the hookah smoking device 100 can be configured with a filter 702 as shown in Figure 7 In some embodiments, the filter 702 is configured to be installed and vertically above the water level of the water contained in the smoke bottle 102. In other words, the filter 702 can be disposed in the bottom region of the stem 106 and above the smoke bottle 102 (or in the top region of the smoke bottle 102).

[0063] When a smoker inhales the bubbled smoke, in response to the inhalation action, a negative pressure is formed inside the smoke bottle 102, causing the smoke to be sucked into the smoke bottle 102 from the smoke bowl 104. Further, in response to the inhalation action, the smoke bypasses the filter 702 and is received into the smoke bottle 102. Once the smoke enters the smoke bottle 102, it bubbles in the smoke bottle water to form bubbled smoke. Subsequently, the user sucks the smoke from the smoke bottle 102 by passing the bubbled smoke through the filter 702. Therefore, when the bubbled smoke from the smoke bottle 102 passes through the filter 702, the filtration process is completed in the filter 702. The user can suck and inhale the bubbled smoke from the steam chamber 118 of the stem 106 through the proximal end of the straw 108. The distal end of the straw 108 is thus disposed above the water level in the smoke bottle 102.
