Description

Arab hookah

Technical Field

The invention belongs to the technical field of articles for smokers, and particularly relates to a hookah.

Background

Arabic HOOKAH (HOOKAH) originally originated in India in the thirteen th century and was popular in the middle east since the beginning of the sixteen century. In the middle east, especially Turkey and Iran in the ancient Oersman empire, hookah was once considered to be a "dancing princess and snake". Later, the tobacco is gradually distributed to Arabic countries, and the tobacco is greatly promoted by Arabic people, so that the tobacco is a common way for folk smoking of tobacco.

After long-term accumulation and precipitation, the structure of the arabian hookah is very mature.

The US1513147 (publication date: 10/28/1924) discloses a conventional arabian hookah. As shown in fig. 1, the liquid container (liquid container)201, the cigarette holder (member)202, the tobacco container (tobaco container)203, the smoke inlet pipe (dried pipe) 204 and the smoke outlet pipe (flexible pipe) 205 are included. Wherein, English in parentheses is extracted from original text, and Chinese is meaning translation. The tobacco container 203, the cigarette holder 202 and the liquid container 201 are connected in turn through screw threads in an airtight manner from top to bottom. The smoke inlet pipe 204 penetrates the smoke base 202 and connects the tobacco container 202 and the liquid container 201. The smoke outlet hose 205 is connected to the liquid container 201, and can be used for a user to suck smoke. The working principle is as follows: the user inhales from the smoke hose 205, and a negative pressure is formed above the liquid surface of the liquid container 201. Due to the pressure difference, the smoke generated by the flue-cured tobacco in the tobacco container 203 enters the liquid in the liquid container 201 through the smoke inlet pipe 204, and is filtered by the liquid, and the smoke is poured above the liquid level of the liquid container 201 and is sucked by the user through the smoke outlet hose 205.

U.S. Pat. No. 3,3882875 (published: 1975, 5, 13) discloses a hookah with an air inlet device. As shown in fig. 2, the upper side of the liquid container of the hookah is provided with an air inlet device 301 having a hole 302 therein for communicating the outside atmosphere with the inside of the liquid container. The working principle is as follows: firstly, a user blocks a pore passage 302 of the air inlet device 301 with fingers, slowly inhales air, and makes smoke enter the upper part of the liquid level after liquid filtration; then the fingers are loosened to continue smoking the smoke. Thus, another air inlet channel can be provided outside the smoke inlet pipe, thereby improving the comfort of smoking.

However, conventional arabian hookah still suffers from some unpleasant drawbacks in use. For example:

1) carbon monoxide (CO) generated by charcoal used for smoking tobacco is basically not filtered by liquid when passing through the liquid along with smoke. After being taken by a user, the smoke can cause mild carbon monoxide poisoning phenomena such as dizziness, nausea and the like.

2) The smoke inlet pipe is directly communicated below the liquid level, and smoke emerges from the smoke inlet pipe and then floats out of the liquid in a large bubble state, so that the smoke cannot be in full contact with the liquid. These fumes are not only difficult to filter effectively, but also to carry away the aromatic compounds in the liquid, and do not allow the user to have a more comfortable experience.

3) For the hookah without the air inlet device, because air can only flow in from the inlet of the tobacco container, if the user inhales too fast, the smoke concentration above the liquid surface is too high and the air concentration is too low, the user is easy to generate the symptom of 'drunk smoke'. For the hookah with the air inlet device, because the position of the air inlet device is close to the tobacco container from the smoke outlet port, if a user inhales too fast, the air concentration above the liquid level is too high, and the smoke concentration is too low, so that the user cannot feel satisfied.

Although some prior arts have proposed improvements to the above-mentioned drawbacks, the effect is not significant.

Chinese patent CN201119417Y (publication date: 2008, 9 and 24) discloses an electric water-heating tobacco pan. As shown in FIG. 3, the hookah has an electric hookah pan including a power plug 401, an electric heating wire 402, and a heat conducting cup 403. The heating wire 402 is externally connected to an external power source through a power plug 401 and generates heat. The heat conducting cup 403 conducts heat generated by the heating wire 402 to the tobacco in the tobacco container, thereby achieving the effect of smoking. Although the problem of carbon monoxide is solved by an electric heating mode, the use is simple and clean, but the joy of smoking the Arabic hookah is also destroyed. Moreover, the open fire charcoal roast comprises the processes of temperature rise and temperature drop, so that the tobacco can generate smoke with layered taste, which is difficult to realize by an electric heating mode.

Chinese patent CN201064181Y (published: 2008, 5 and 28) discloses a hookah. As shown in FIG. 4, the hookah has a smoke inlet pipe 501, which has a plurality of openings 502 at its end extending below the liquid level. When the smoke enters the liquid through the smoke inlet pipe 501, the foaming effect is generated through the open holes 502, so that the contact between the smoke and the liquid is increased. Although, the problem of flue gas and liquid contact is solved to the mode of trompil, promotes the taste of filter effect and flue gas, its effect is limited only locally. Because the liquid in the whole liquid container is difficult to effectively disturb, after a period of time, harmful compounds such as tar are accumulated in the liquid near the smoke inlet pipe port, and the filtering effect and the taste of smoke are gradually reduced.

Chinese patent CN2501324Y (publication date: 2002, 7, 24) discloses a hookah with adjustable smoking concentration. As shown in fig. 5, the hookah has an inlet regulator valve 600 including a fitting 601 and a cap 606. The connector 601 is provided with an inlet pipe 602 communicating with the liquid container. The cap 606 is provided with an opening 605 to the atmosphere. The adapter 601 and the cap 606 are connected by screw threads, and the inner space between the two is provided with a choke member 603 that can air tightly block the port of the intake pipe 602, and a spring 604 that urges the choke member 603 away from the port of the intake pipe 602. By rotating the distance between the adjusting joint 601 and the cap 606, whether the air inlet pipe 602 is communicated with the outside atmosphere or not and the air flow can be controlled, so that the effect of adjusting the smoking concentration is achieved. Although such an air intake regulating valve solves the problem of regulating the intake air, improving the smoking comfort for the user, it requires manual regulation. Moreover, if a plurality of persons share the water smoke, it is difficult to satisfy the inhalation habit of the plurality of persons at the same time.

In summary, there is no Arabian hookah which can automatically adjust the smoke and air intake while maintaining the traditional fun.

Detailed Description

The Arabic hookah of the present invention will be described in detail below with reference to the accompanying drawings.

First embodiment

See fig. 6. The water tobacco 100 of Arabic of the present invention has a tobacco pot 101, a tobacco seat 102 and a liquid container 108 connected in this order from top to bottom. The cigarette holder 102 is provided with a cigarette inlet pipe 107 communicated with a liquid container 108, and is provided with a cigarette outlet hose 106.

The smoke pan 101 is used to contain and smoke tobacco. The smoke pan 101 of the present invention is a conventional Turkish smoke pan, and comprises a pan body (not shown), a smoke inlet chamber (not shown) and a base (not shown) which are connected in sequence. A plurality of smoke inlet holes (not shown) are arranged between the pan body and the smoke inlet cavity and between the smoke inlet cavity and the base. The pot body can contain tobacco, tobacco paste or smoke stone and the like. Tinfoil or charcoal mesh can be arranged above the pot body, and the charcoal is placed for smoking and roasting. The inner side of the base is provided with an airtight rubber sleeve or a plastic thread structure which can be connected with the cigarette holder 102 in an airtight way.

The smoke holder 102 is used for conducting and smoking smoke. The cigarette holder 102 of the present invention is a lotus-root shaped cigarette holder, which includes an upper cigarette holder (not shown) and a lower cigarette holder (not shown). The outer side of the upper end of the upper cigarette seat is provided with an airtight rubber sleeve or a plastic thread structure which can be connected with the base of the cigarette pot 101 in an airtight way, so that smoke is conducted.

The middle part of the upper cigarette holder can be clamped with the charcoal ash tray 103 so as to receive charcoal ash or cigarette ash falling from the cigarette pot 101. An airtight connection is provided between the upper and lower smoke holder through which a smoke inlet pipe 107 passes, the upper end opening of which is located in the upper smoke holder and faces the base of the smoke pot 101, and the lower end of which extends into the liquid container 108. Therefore, the smoke generated in the smoke pan 101 enters the upper smoke seat and then enters the liquid container 108 along the smoke inlet pipe 107.

The lower smoke seat is provided with a smoke outlet 105 and an air inlet valve 104. The smoke outlet interface 105 may be hermetically connected to a smoke outlet hose 106, such that a user may draw smoke through the smoke outlet hose 106. The intake valve 104 includes an intake passage (not shown) and a blocking element (not shown). The air inlet channel is formed by extending the outer wall of the lower smoke seat to the inclined upper side of the outer side and is communicated with the lower smoke seat and the external atmosphere. The inner diameters of both ends of the air inlet channel are smaller than the inner diameter of the middle part of the air inlet channel. The blocking member is accommodated in the middle of the intake passage. The blocking element can only move in the middle of the inlet channel and cannot fall out of the inlet channel. Because the air inlet channel extends obliquely upwards, the blocking element generally falls under the action of gravity at the end of the air inlet channel close to the lower smoke seat.

When the smoke sucking device is used normally, a user inhales to enable the interior of the lower smoke seat to be at negative pressure, the blocking element is forced to be abutted inwards by external atmosphere and clamped at the position with the smaller inner diameter of the air inlet channel, and therefore the lower smoke seat is isolated from the external atmosphere, and the smoke sucking device is convenient for the user to suck smoke. When the smoke concentration in the lower smoke seat is too high, the user blows air to enable the air pressure in the lower smoke seat to be higher than the external atmosphere, the blocking element is forced to move towards the middle of the smoke inlet channel and to be suspended (or propped) at a position with a larger inner diameter, and therefore the lower smoke seat is communicated with the external atmosphere. The smoke in the lower smoke seat flows out due to the pressure difference, so that the smoke concentration in the lower smoke seat is reduced.

The liquid container 108 is used to contain liquid for filtering the flue gas. For example, clear water, ice-water mixture, red wine, milk, black tea, etc. may be added to the beverage according to the preference of the user. The liquid container 108 is shaped to be narrow at the top and wide at the bottom. The upper end of the liquid container 108 is provided with an airtight rubber sleeve or a plastic thread structure, which can be connected with the lower cigarette holder of the cigarette holder 102 in an airtight manner, so as to conduct smoke. The smoke inlet pipe 107 passes through the lower smoke base of the smoke base 102 and the upper part of the liquid container 108, and the lower end thereof is close to the bottom of the liquid container 108. When in use, the liquid is needed to be added to immerse the lower end of the smoke inlet pipe 107 so as to realize filtration.

The hookah 100 of the present invention further comprises a filter element 109, a smoke exit regulating device 110 and a smoke inlet device 111.

The filter element 109 is used for filtering carbon monoxide (CO) in the flue gas, is accommodated above the smoke inlet pipe 107 in the smoke base 102, and is clamped on the inner wall of the upper smoke base of the smoke base 102. Referring to fig. 7, the filter element 109 comprises two hemispherical screens (1091, 1092) each having teeth and grooves (not shown) on its periphery for engaging to form a spherical filter element. The filter element 109 is filled with a binary Hopcalite (Hopcalite) agent. Binary Hopcalite (Hopcalite) is composed of 40% CuO and 60% MnO₂And (4) forming.

The working principle is as follows: carbon monoxide (CO) generated by insufficient combustion of the carbon is converted into harmless carbon dioxide (CO) by the hopcalite catalyst when passing through the filter element 109 along with high-temperature flue gas₂). The reaction mechanism is shown in the study of Hogata catalyst for low-temperature oxidation of Zhangjin, Yi Yan Hua, Zhangmei and CO [ J]Industrial catalysis, 6 months 2007, volume 15, phase 6: 58-59.

The smoke output adjusting device 110 can automatically adjust the smoke output density according to the inhalation of the user. Referring to fig. 8, the smoke control device 110 is provided in the smoke hose 106 and has a sleeve 1101. A through hole 1102 is opened in the sleeve 1101, and the inner diameters of both ends are larger than the inner diameter of the middle part. Both ends of the through hole 1102 are connected to the 2-stage smoke exhaust hose 106 in an airtight manner. The middle of the through hole 1102 is opened with an air hole 1103, which communicates with the atmosphere, and the inner diameter of which decreases from inside to outside. A rubber plate 1104 is placed upside down in the air hole 1103 with its mouth facing the inside of the through hole 1102 and bottom facing the outside atmosphere. A bolt 1106 is threaded through the sleeve 1101 through a threaded hole (not shown) and attached to the bottom of the rubber disk 1104 (the air hole 1103 is connected to the outside atmosphere through 1 or several openings around the threaded hole). The joint of the bolt 1106 and the rubber disc 1104 is also provided with a rubber gasket 1105 with a diameter larger than the disc bottom of the rubber disc 1104. The rubber disk 1104 is moved in the air hole 1103 in the axial direction of the bolt 1106 by rotating the bolt 1106.

The threaded fit of the bolt 1106 with the threaded hole satisfies the following operating conditions: 1) referring to fig. 9, the rubber disc 1104 can be in the first position, the outer side surface of the rubber disc 1104 is in close contact with the rubber gasket 1105 and the inner wall of the air hole 1103, and the air hole 1103 is always sealed; 2) referring to fig. 8 and 10, the rubber plate 1104 may be in a second position in which the side of the rubber plate 1104 contacts the inner wall of the air hole 1103 and the rubber gasket 1105 does not contact the inner wall of the air hole 1103, and in a normal state, the rubber plate 1104 seals the air hole 1103 and in a deformed state (the mouth of the rubber plate 1104 is bent inward), a gap is formed between the rubber plate 1104 and the air hole 1103.

The working principle is as follows: if the user does not need to automatically adjust the smoke density, the bolt 1106 is rotated to place the rubber plate 1104 in the first position. At this time, the air hole 1103 is always sealed, and the user directly sucks the smoke above the liquid level in the liquid container 1108. If the user desires to automatically adjust the smoke density, the bolt 1106 is rotated to place the rubber plate 1104 in the second position. At this time, only the side surface of the rubber plate 1104 is in contact with the inner wall of the air hole 1103. Since the inner diameter of the central portion of the through-hole 1102 is reduced, the flow velocity of the flue gas passing therethrough is increased. According to the Bernoulli principle (approximately equal height of the fluid due to the narrow middle of the through hole 1102), the internal pressure of the fluid decreases as the flow rate increases. When a user inhales slowly, the pressure of smoke in the through hole 1102 is higher than that of the external atmosphere, the rubber disc 1104 still seals the air hole 1103, and the user can inhale smoke with higher concentration; when a user inhales fast, the smoke pressure in the through hole 1102 is reduced until the smoke pressure is smaller than that of the external atmosphere, the rubber disc 1104 deforms, a gap is formed between the rubber disc and the air hole 1103, and the external air is gushed into the through hole, so that the smoke flow concentration is reduced. The gap can be enlarged along with the increase of the inhalation speed of the user, and more air is introduced, thereby preventing the user from choking or getting drunk due to the urgent inhalation.

The smoke inlet 111 is used to emit smoke and disturb the liquid in the liquid container 108. Referring to fig. 11, the smoke inlet 111 is disposed at the lower end of the smoke inlet pipe 107 and has a housing 1111 with an outer contour of a spheroid or ellipsoid with two flat ends. An injection port 1112 is formed at a position where the housing 1111 is connected to the smoke inlet pipe 107, and the inner diameter thereof is reduced from the top to the bottom. A smoke outlet (not shown) is formed at the lower end of the housing 1111 and includes a plurality of foaming holes 1115. A flow dividing element 1113 and a flow rectifying element 1114 are also provided within the housing 1111. In this example, the flow dividing member 1113 is a concave member disposed near the middle of the interior space of the housing 1111. The rectifying element 1114 is a two-cylinder element, which is disposed between the flow dividing element 1113 and the smoke outlet and is symmetrical along the central axis of the injection port 1112. A flow splitting cavity (not shown) is formed between the injection port 1112 and the flow splitting element 1113. The flow dividing member 1113 and the inner wall of the housing 1111 form therebetween a first flow dividing channel 1116 and a second flow dividing channel 1117, respectively. A rectifying cavity 1118 is formed between the flow dividing element 1113 and the rectifying element 1114.

The working principle is as follows: referring to fig. 12 and 13, because the inner diameter of the injection port 1112 is reduced, the flue gas passing through the injection port 1112 accelerates to flow into the branch chamber. The flue gas flows into the concave portion of the flow dividing member 1113 and then is divided into left and right. First, assume that a relatively large flow of flue gas exits the first diversion channel 1116 (see the direction of the arrow in FIG. 12). At this point, a high pressure zone will be formed in the vicinity of the recess near the first diversion channel 1116. Then, a second stream of flue gas with a larger flow rate will flow out of the second diversion channel 1117 (see the direction of the arrow in fig. 13) due to the influence of the aforementioned high pressure zone. At this time, a high pressure region is formed in the vicinity of the concave portion near the second diversion passage 1117. The above process is repeated as the flue gas flows in. However, since the formation of the high pressure zone is related to the flue gas flow rate, which is not constant, the complaint process is not always maintained in a left-to-right order. Overall, the flue gas flow will split randomly between the first split channel 1116 and the second split channel 1117.

The flue gas flowing out of the first diversion channel 1116 (or the second diversion channel 1117) enters the rectification cavity 1118 and is obstructed by the rectification element 1114. The obstruction reduces the velocity of mainstream smoke on the one hand and prevents small portions of smoke from flowing back through the second diversion channel 1117 (or the first diversion channel 1116) and disturbing the diversion chamber on the other hand. The mainstream smoke then passes through the foaming holes 1115 and enters the liquid in the form of small bubbles. Also, since the small bubble flow randomly deflects left and right, the flow exchange of the liquid throughout the liquid container 108 will be disturbed. Therefore, the filtering of the liquid to the smoke can be enhanced, and the smoke is helped to carry more aromatic compounds out of the liquid, so that the taste of the smoke is improved.

Second embodiment

Other P-type oxide (P-type axid) catalysts can be selected for the filler of the filter element 109. P-type oxides are a class of metal oxides that conduct charge with holes as carriers. The P-type oxide includes copper oxide, manganese oxide, silver oxide, aluminum oxide, and the like.

In a second embodiment, a single component catalyst is used, specifically a honeycomb cordierite loaded with copper oxide (CuO). The reaction mechanism is shown in Luguan, Wanren, the action of cerium oxide in non-noble metal oxide catalyst-NO + CO reaction [ J ], Chinese rare earth academy, 12 months in 1991, volume 9, phase 4: 330. among them, honeycomb cordierite is used as a support instead of ceria because it is beautiful and has good thermal stability.

Third embodiment

In the third embodiment, a single component catalyst is used, specifically, a honeycomb cordierite carrying MnO2 nanocrystalline manganese oxide. The reaction mechanism is shown in Liu's duckweed, Yuan Bao, Ringbacle and the like, the research on the catalytic activity of the nanocrystalline manganese oxide on the CO oxidation reaction, the report of chemico-physics, 2 months 1999, volume 12, phase 1: 83-84.

Fourth embodiment

Other deformable air blocking members are provided in the air hole 1103 of the smoke discharge adjusting device 110.

The fourth embodiment employs a hollow rubber ball as the gas barrier member, and a rubber gasket (not shown) is not provided. Therefore, the threaded engagement of the bolt 1106 with the threaded hole satisfies the following operational conditions: 1) the rubber ball can be positioned at the first position, the outer side surface of the rubber ball is in full contact with the inner wall of the air hole 1103 and is difficult to deform again, and therefore the air hole 1103 is sealed all the time; 2) the rubber ball can be located at the second position, the outer side surface of the rubber ball is in contact with the inner wall of the air hole 1103, and deformation is allowed to occur again, so that when the rubber ball is in a normal state, the air hole 1103 is sealed by the rubber ball, and when the rubber ball is in a deformed state (the rubber ball is concave), a gap is formed between the rubber ball and the air hole 1103.

Fifth embodiment

The smoke control device 110 may move the choke member between the first position and the second position in other ways.

The fifth embodiment employs a rubber sheet as the gas barrier member, and is not provided with a rubber gasket. In addition, rubber rods are used instead of bolts. The rubber rod passes through the sleeve 1101 through a through hole and is connected to a rubber sheet (not shown). The rubber rod is in interference fit with the through hole, and the rubber rod can be positioned in a general state and can move when pushed and pulled forcefully. Moreover, the cooperation between the rubber rod and the through hole satisfies the following action states: 1) the rubber sheet can be brought into such a first position: the end face of the film is in full contact with the inner wall of the air hole 1103 and is difficult to deform again, so that the air hole 1103 is always sealed; 2) since the rubber sheet can be brought into such a second position and the edge of the rubber sheet is in contact with the inner wall of the air hole 1103, the rubber sheet seals the air hole 1103 in a normal state and a space is formed between the rubber sheet and the air hole 1103 in a deformed state (the rubber sheet is bent into the through hole).

Sixth embodiment

The smoke intake device 111 is not provided with a rectifying portion. Thus, a majority of the smoke exiting the first diversion channel 1116 (or the second diversion channel 1117) flows in the direction in which the first diversion channel 1116 (or the second diversion channel 1117) extends, enters the liquid through the bubbling holes 1115 in the form of small bubbles, and a small portion of the smoke will flow back to the diversion chamber along the second diversion channel 1117 (or the first diversion channel 1116). At this point, the small portion of smoke will cause some disturbance to the mainstream smoke as subsequent mainstream smoke will flow along the second diversion channel 1117. However, because the flow rate of the mainstream smoke is significantly greater than the flow rate of the small portion of smoke, the mainstream smoke will still entrain the small portion of smoke to flow out along the second diversion channel 1117. In general, the smoke outlet device 111 can still make the smoke split randomly left and right.

Seventh embodiment

Other shapes of the fairing elements 1114 can be used with the smoke intake device 111. In this example, the rectifying element 1114 is embodied as an inverted triangular element that is symmetrical about the central axis of the injection port 1112. And the base of the triangle faces the shunt element 1113 and the apex angle faces the foaming orifice 1115.

Eighth embodiment

The smoke inlet means 111 may employ other shapes of the flow dividing element 1113. In this example. The shunt element 1113 is embodied as a crescent-shaped element that is symmetrical about the central axis of the injection port 1112. The concave portion of the crescent is directed to the injection port 1112, and the convex portion is directed to the rectifying element 1114.

In summary, the invention provides an arabian hookah which can automatically adjust the smoke inlet and the air inlet while keeping the traditional fun by adding a filter element, a smoke inlet device and a smoke outlet adjusting device. The method has the following remarkable technical effects:

1) and carbon monoxide is removed by the filter element, thereby contributing to the health of the smoker.

2) Through the flue gas of entering cigarette device random reposition of redundant personnel entering liquid, effectively carry out the disturbance to the liquid in the whole container, both can promote the filtration of liquid to the flue gas, help the flue gas to take more aromatic compounds in the liquid again to promote the flue gas taste.
