Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of fumigators, and in particular to a fumigator for cooling and inhalation. Background Art
[0002] Generally, a fumigator mainly includes a fumigator body and an atomizer. The atomizer is provided with a heating pot for storing herbal materials. By heating the heating pot, the herbal materials therein can be atomized to generate mist. When a user inhales the mist, the mist in the heating pot enters the mouthpiece and is inhaled by the human body. At the same time, external gas enters the heating pot to assist the combustion of the herbal materials and achieve air pressure balance. Among them, the mist generated by the combustion of some herbal materials has a relatively high temperature. In order to prevent the mist from scalding the user's throat, the current practice is to pass the mist through a container filled with water, and then the mist bubbles out from the water surface and is discharged from the mouthpiece. After passing through the water, part of the herbal components of the mist will be filtered out, resulting in poor use effects.
[0003] In addition, when the herbal paste in the heating pot is heated and turned into a liquid state, and then boils to form mist, the heating pot for placing the herbal paste is usually a flat pan, and the middle part of the heating pot is heated relatively slowly, resulting in a low efficiency of generating mist. Summary of the Invention
[0004] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a fumigator for cooling and inhalation, which uses an extended exhaust heat exchange tube to cool the mist to prevent scalding the user's respiratory tract, and also avoids losing the effective components of the mist, ensuring the purity of the taste of the mist generated when burning herbal materials.
[0005] A fumigator for cooling and inhalation according to an embodiment of the present invention includes: a fumigator body, a heating pot assembly, and a mouthpiece assembly. A heat exchange container is connected between the heating pot assembly and the mouthpiece assembly. The heat exchange container is provided with a reciprocally bent or reciprocally coiled exhaust heat exchange tube. Two ends of the exhaust heat exchange tube are respectively communicated with the exhaust end of the heating pot assembly and the mouthpiece assembly. A cavity is defined between the exhaust heat exchange tube and the heat exchange container. The heat exchange container is provided with an air inlet and an air outlet. The air inlet connects the external environment with the cavity, and the air outlet connects the cavity with the air inlet end of the heating pot assembly.
[0006] The fumigator with a detachable and replaceable heating container according to an embodiment of the present invention has at least the following beneficial effects:
[0007] When the user inhales while holding the mouthpiece assembly, the high-temperature mist generated in the heating pot assembly passes through the reciprocatingly bent or reciprocatingly coiled exhaust heat exchange tube in the heat exchange container. The exhaust heat exchange tube exchanges heat with the medium in the cavity, and then is discharged from the mouthpiece assembly. At the same time, the external gas sequentially passes through the air inlet, the cavity, and the air outlet and then enters the heating pot assembly. When the external gas passes through the cavity, it exchanges heat with the mist in the exhaust heat exchange tube, which helps to reduce the temperature of the mist, achieving the effect of cooling during inhalation, avoiding scalding the user's respiratory tract. The external gas itself realizes a temperature rise, which is beneficial to assisting the combustion of the herbal materials, and also avoids the loss of the effective components of the mist due to the traditional method of discharging the mist through water, ensuring the purity of the taste of the mist generated when burning the herbal materials.
[0008] In some embodiments of the present invention, the heat exchange container is generally cylindrical, the exhaust heat exchange tube spirally winds upward around the axis of the heat exchange container, and the upper end surface of the heat exchange container is convexly provided with a first exhaust pipe and a second exhaust pipe. The first exhaust pipe connects one end of the exhaust heat exchange tube and the exhaust end of the heating pot assembly, and the second exhaust pipe connects the other end of the exhaust heat exchange tube and the mouthpiece assembly.
[0009] In some embodiments of the present invention, both the air inlet and the air outlet are opened on the upper end surface of the heat exchange container.

The mouthpiece assembly, the first exhaust pipe, and the second exhaust pipe are all tightly and detachably inserted into the installation cover.
[0011] In some embodiments of the present invention, the mounting cover includes a bottom cover and a face cover. The upper end surface of the bottom cover is recessed downward to form a first sunken groove with an upward opening. The face cover closes the opening of the first sunken groove.

[0012] In some embodiments of the present invention, there is a gap between the exhaust heat exchange pipe and the inner peripheral wall of the heat exchange container. An intake extension pipe that passes downward through the hollow position of the exhaust heat exchange pipe is provided inside the heat exchange container. The upper end of the intake extension pipe communicates with the intake port. The lower end of the intake extension pipe extends to be close to the inner bottom surface of the heat exchange container.
[0013] In some embodiments of the present invention, the intake port is located in the middle of the upper end surface of the heat exchange container. Two opposite exhaust holes are horizontally provided at the lower end of the intake extension pipe. The two air outlets are arranged symmetrically about the center of the air outlet to correspond to the two exhaust holes.
[0014] In some embodiments of the present invention, the heat exchange container, the exhaust heat exchange pipe, and the intake extension pipe are an integral structure made of glass material or quartz material.
[0015] In some embodiments of the present invention, the heating pot assembly includes a pot body. A bulge portion located in the middle of the inner cavity of the pot body protrudes from the inner bottom wall of the pot body. The bulge portion has a receiving cavity with a downward opening. The opening edge of the receiving cavity is connected to the outer bottom wall of the pot body. A heating element is in contact with the outer bottom wall of the pot body.

Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.
[0030] In the description of the present invention, it should be understood that for the orientation description, such as the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
[0031] In the description of the present invention, the meaning of "a number of" is one or more, the meaning of "a plurality of" is two or more, and understandings such as "greater than", "less than", "exceeding", etc. do not include the present number, and understandings such as "above", "below", "within", etc. include the present number. If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.
[0032] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0033] Referring to Figures 1 to 4 , a fumigator for cooling and inhaling of the present invention includes: a fumigator main body 100, a heating pot assembly 200, and a mouthpiece assembly 300. A heat exchange container 400 is connected between the heating pot assembly 200 and the mouthpiece assembly 300. A reciprocatingly bent or reciprocatingly coiled exhaust heat exchange tube 410 is provided in the heat exchange container 400. Two ends of the exhaust heat exchange tube 410 are respectively communicated with the exhaust end of the heating pot assembly 200 and the mouthpiece assembly 300. A cavity 420 is defined between the exhaust heat exchange tube 410 and the heat exchange container 400. The heat exchange container 400 is provided with an air inlet 430 and an air outlet 440. The air inlet 430 connects the external environment with the cavity 420, and the air outlet 440 connects the cavity 420 and the air inlet end of the heating pot assembly 200.
[0034] When the user inhales while holding the mouthpiece assembly 300, the high-temperature mist generated in the heating pot assembly 200 passes through the reciprocatingly bent or reciprocatingly coiled exhaust heat exchange tube 410 in the heat exchange container 400. The exhaust heat exchange tube 410 exchanges heat with the medium in the cavity 420, and then is discharged from the mouthpiece assembly 300. At the same time, the external gas sequentially passes through the air inlet 430, the cavity 420, and the air outlet 440 and then enters the heating pot assembly 200. When the external gas passes through the cavity 420, it exchanges heat with the mist in the exhaust heat exchange tube 410, which helps to reduce the temperature of the mist, achieving the effect of cooling and inhaling, avoiding scalding the user's respiratory tract. The external gas itself realizes a temperature rise, which is beneficial to assisting the combustion of the herbal materials and also avoids the loss of the effective components of the mist in the traditional method of discharging the mist through water, ensuring the purity of the taste of the mist generated when burning the herbal materials. It can be understood that water can also be injected into the cavity 420 to increase the rate of cooling of the mist in the exhaust heat exchange tube 410. Since the mist runs in the exhaust heat exchange tube 410, there is also no problem of loss of the effective components of the mist.
[0035] See Figure 2 and Figure 3, in some embodiments of the present invention, the heat exchange container 400 is generally cylindrical, the exhaust heat exchange tube 410 is spirally wound upward around the axis of the heat exchange container 400, and the upper end surface of the heat exchange container 400 is convexly provided with a first exhaust pipe 450 and a second exhaust pipe 460. One end of the exhaust heat exchange tube 410 is connected to the exhaust end of the heating pot assembly 200 through the first exhaust pipe 450, and the other end of the exhaust heat exchange tube 410 is connected to the nozzle assembly 300 through the second exhaust pipe 460. It can be understood that when the mist generated in the heating pot assembly 200 is discharged, it enters the exhaust heat exchange tube 410 through the first exhaust pipe 450, and after traveling spirally upward or downward along the exhaust heat exchange tube 410, it enters the nozzle assembly 300 through the second exhaust pipe 460 and is thus inhaled by the user. The exhaust heat exchange tube 410 with the above structure is beneficial to fully extend the travel of the mist from the heating pot assembly 200 to the nozzle assembly 300, so as to fully exchange heat with the medium in the cavity 420 and achieve a better cooling effect.
[0036] See Figure 2 , Figure 3 and Figure 5 , in some embodiments of the present invention, both the air inlet 430 and the air outlet 440 are opened on the upper end surface of the heat exchange container 400. The heating pot assembly 200 is located on one side of the heat exchange container 400. The air inlet end and the exhaust end of the heating pot assembly 200 are both provided at its upper end. The upper end of the heating pot assembly 200 and the upper end of the heat exchange container 400 are connected through a mounting cover 500. The mounting cover 500 is provided with a first air inlet channel 510 connecting the external environment to the air inlet 430, a second air inlet channel 520 connecting the air outlet 440 to the air inlet end of the heating pot assembly 200, a first exhaust channel 530 connecting the exhaust end of the heating pot assembly 200 to the first exhaust pipe 450, and a second exhaust channel 540 connecting the second exhaust pipe 460 to the nozzle assembly 300. Through the above structure, while the mounting cover 500 connects the upper end of the heating pot assembly 200 and the upper end of the heat exchange container 400, the direct connection of the air intake path of the external gas and the exhaust path of the mist is realized, greatly simplifying the structure, assembly process, etc. of the fumigator.
[0037] See Figure 2 and Figure 4, in some embodiments of the present invention, the mounting cover 500 is made of silica gel material. The mounting cover 500 is provided with two glass tubes that respectively form the first exhaust passage 530 and the second exhaust passage 540. The nozzle assembly 300, the first exhaust pipe 450, and the second exhaust pipe 460 are all tightly and detachably inserted into the mounting cover 500. It can be understood that when the nozzle assembly 300, the first exhaust pipe 450, and the second exhaust pipe 460 are inserted into the mounting cover 500, the silica gel mounting cover 500 helps to ensure the airtightness between any two butted pipe fittings and is also convenient for detachable installation to replace or maintain the heat exchange container 400. Among them, when the high-temperature mist passes through the two glass tubes serving as the first exhaust passage 530 and the second exhaust passage 540, it is not easy to cause cross-taste, ensuring the purity of the taste of the mist generated when burning herbal materials.
[0038] See Figure 4 and Figure 5 , in some embodiments of the present invention, the mounting cover 500 includes a bottom cover 501 and a face cover 502. The upper end surface of the bottom cover 501 is recessed downward to form a first sink 503 with an upward opening. The face cover 502 closes the opening of the first sink 503. The two ends of the first sink 503 are provided with a first smoke exhaust through hole 504 and a second smoke exhaust through hole 505 penetrating in the up-down direction. The first exhaust passage 530 is connected between the first smoke exhaust through hole 504 and the second smoke exhaust through hole 505. A first air inlet hole 506 and a second air inlet hole 507 located between the first smoke exhaust through hole 504 and the second smoke exhaust through hole 505 are penetratingly provided in the first sink 503 in the up-down direction. The heating pot assembly 200 has an exhaust smoke pipe 210 and a gas supply pipe 220 located on the outer periphery of the exhaust smoke pipe 210. The exhaust smoke pipe 210 is inserted into the first smoke exhaust through hole 504. The gas supply pipe 220 communicates with the first air inlet hole 506. The second air inlet hole 507 communicates with the air outlet 440. The second smoke exhaust through hole 505 communicates with the first exhaust pipe 450.
[0039] It should be noted that if the first exhaust passage 530 and the second exhaust passage 540 are directly formed inside the mounting cover 500, the materials forming the first exhaust passage 530 and the second exhaust passage 540 are liable to generate peculiar smells due to heat transfer of high-temperature fog, which affects the user experience. Therefore, the mounting cover 500 with the above structure is assembled by a bottom cover 501 and a face cover 502. The first sink 503 is used to accommodate the glass tube forming the first exhaust passage 530. The two ends of the glass tube are butted against the first smoke exhaust through hole 504 and the second smoke exhaust through hole 505, thereby solving the problem of peculiar smell generated by fog. In addition, the face cover 502 closes the opening of the first sink 503 so that the first air inlet hole 506 and the second air inlet hole 507 are directly communicated. Since the temperature of the external gas is relatively low before entering the heating pot assembly 200, the external gas passes through the cavity 420 and then successively passes through the air outlet 440, the second air inlet hole 507, the first air inlet hole 506 and the air supply pipe 220, and thus reaches the inside of the heating pot assembly 200 to assist in burning the herbal materials.
[0040] See Figure 2 and Figure 3 , in some embodiments of the present invention, there is a gap between the exhaust heat exchange tube 410 and the inner peripheral wall of the heat exchange container 400. An air inlet extension tube 600 is provided inside the heat exchange container 400 and passes downward through the hollow position of the exhaust heat exchange tube 410. The upper end of the air inlet extension tube 600 is communicated with the air inlet 430, and the lower end of the air inlet extension tube 600 extends to be close to the inner bottom surface of the heat exchange container 400. It should be noted that if there is no air inlet extension tube 600, when the external gas enters the cavity 420 from the air inlet 430, some of the gas may directly be discharged from the air outlet 440 to the heating pot assembly 200 without being fully heat-exchanged with the exhaust heat exchange tube 410. The fog in the exhaust heat exchange tube 410 is not fully cooled, resulting in a relatively high temperature of the fog reaching the suction nozzle assembly 300 and being liable to scald the user's throat. The external gas itself does not achieve sufficient temperature rise, which is not conducive to assisting in burning the herbal materials, causing waste of heat energy, and the gas entering the cavity 420 is also liable to generate more turbulence and result in a relatively large noise. In the above embodiments, the lower end of the air inlet extension tube 600 extends to be close to the inner bottom surface of the heat exchange container 400, and the air outlet 440 is located at the upper end of the heat exchange container 400. During the process of the gas flowing upward after being discharged and being discharged from the air outlet 440, the external gas can be fully in contact with the exhaust heat exchange tube 410 for heat exchange, thereby solving the problems raised above. In addition, the air inlet extension tube 600 passes downward through the hollow position of the exhaust heat exchange tube 410, and the spiral exhaust heat exchange tube 410 has a heat radiation effect on the air inlet extension tube 600 located in the middle thereof, which also helps to increase the wall temperature of the air inlet extension tube 600.
[0041] See Figure 3 andFigure 4 , in some embodiments of the present invention, the air inlet 430 is located in the middle of the upper end face of the heat exchange container 400. Two opposite exhaust holes 610 are horizontally arranged at the lower end of the air inlet extension pipe 600. The two air outlet ports 440 are arranged symmetrically about the center of the air outlet port 440 to correspond to the two exhaust holes 610. It can be understood that the gas discharged from the lower end of the air inlet extension pipe 600 generates two opposite jet flows. The two air flows are horizontally blown towards the inner peripheral wall of the heat exchange container 400, which helps to quickly disperse into the cavity 420 and avoid the lower end of the air inlet extension pipe 600 blowing directly downward on the bottom wall of the heat exchange container 400 to generate excessive turbulence. The positions of the two air outlet ports 440 help to increase the air intake flow rate at the air intake end of the heating pot assembly 200.
[0042] In some embodiments of the present invention, the heat exchange container 400, the exhaust heat exchange pipe 410, and the air inlet extension pipe 600 are an integral structure made of glass material or quartz material. First, the heat exchange container 400, the exhaust heat exchange pipe 410, and the air inlet extension pipe 600 made of glass material or quartz material help to reduce the probability of gas crosstalk in their traveling paths and ensure the purity of the smell of the mist generated when burning herbal materials. In addition, the heat exchange container 400, the exhaust heat exchange pipe 410, and the air inlet extension pipe 600 being an integral structure made of glass material or quartz material is beneficial to achieving a lightweight effect, making the fumigator easier to hold and providing a better experience during long-term use. Specifically, the exhaust heat exchange pipe 410 and the air inlet extension pipe 600 are first separately fired, and then the exhaust heat exchange pipe 410 and the air inlet extension pipe 600 are respectively positioned and fired to obtain the heat exchange container 400. The integral structure composed of the heat exchange container 400, the exhaust heat exchange pipe 410, and the air inlet extension pipe 600 not only has a low cost, but also has a stable connection and is beneficial to rapid heat dissipation. Of course, in other embodiments, the heat exchange container 400, the exhaust heat exchange pipe 410, and the air inlet extension pipe 600 can also be made of thin-walled stainless steel sheets and then formed into an integral structure by welding and fixing, but compared with the integral structure made of the above-mentioned glass material or quartz material, the cost and manufacturing difficulty are higher.
[0043] See Figures 6 to 8, in some embodiments of the present invention, the heating pot assembly 200 includes a pot body 230. A drum portion 240 is convexly provided on the inner bottom wall of the pot body 230 and is located in the middle of the inner cavity of the pot body 230. The drum portion 240 has a receiving cavity 241 with an opening facing downward. The opening edge of the receiving cavity 241 is connected to the outer bottom wall of the pot body 230. A heating element 250 is in contact with the outer bottom wall of the pot body 230. The heating element 250 has a secondary heating portion extending into the receiving cavity 241 to contact the inner wall of the receiving cavity 241. In the heating pot assembly 200 with the above structure, the drum portion 240 is convexly provided on the inner bottom wall of the pot body 230, and the heating element 250 contacts the outer bottom wall of the pot body 230 and uses the secondary heating portion to contact the inner wall of the receiving cavity 241 corresponding to the drum portion 240, so that the contact area between the bottom of the pot body 230 and the herbal paste is increased, and the heated drum portion 240 located in the middle of the inner cavity of the pot body 230 is beneficial to quickly heating the herbal paste in the middle of the pot body 230, achieving a fast and uniform heating effect, thereby improving the atomization efficiency.
[0044] Specifically, the drum portion 240 is formed by protruding upward from the bottom wall of the pot body 230, and the thickness of the drum portion 240 is the same as that of the bottom wall of the pot body 230, that is, the pot body 230 and the drum portion 240 are an integral structure, which is beneficial to simplifying the production process and reducing the manufacturing cost. Moreover, since the thickness of the drum portion 240 is the same as that of the bottom wall of the pot body 230, it is beneficial to the uniform heating of the bottom wall of the pot body 230 and the drum portion 240, and to avoid the insufficient heating of the drum portion 240 and the difficulty in melting the herbal paste. It can be imagined that the pot body 230 and the drum portion 240 can be made by means of integral casting, powder metallurgy, machining, etc. Of course, the drum portion 240 can also be formed on the bottom wall of the pot body 230 by stamping, and at this time, the thickness dimension of the drum portion 240 is slightly smaller than the thickness of the bottom wall of the pot body 230.
[0045] See Figure 6 , Figure 7 and Figure 8, in some embodiments of the present invention, the bulging portion 240 is generally conical and gradually narrows from bottom to top. After the herbal paste contacting the surface of the bulging portion 240 melts into a liquid, it can flow along the slope of the bulging portion 240 to the inner bottom wall of the pot body 230 and be continuously heated, which is conducive to quickly atomizing the liquid into mist; the heating element 250 is a heating wire, and the heating wire includes a spiral disc portion 251 and a spiral tower portion 252 wound together. The spiral disc portion 251 is attached to the outer bottom wall of the pot body 230, and the spiral tower portion 252 extends spirally upward along the inner peripheral wall of the accommodating cavity 241. The spiral tower portion 252 is the above-mentioned secondary heating portion. The heating element 250 with this structure is very simple, has a low cost, and has better heating uniformity at various positions on the bottom of the pot body 230; a heat conduction support 260 is provided below the pot body 230, and an insulating heat conduction sheet 270 is clamped between the heat conduction support 260 and the spiral disc portion 251. The heat conduction support 260 has a heat transfer portion 261 contacting the outer peripheral wall of the pot body 230. The heat conduction support 260 and the insulating heat conduction sheet 270 are both provided with through holes opposite to the spiral tower portion 252, and one end of the heating wire can pass downward through the through holes. Among them, the spiral disc portion 251 transfers heat to the heat conduction support 260 through the insulating heat conduction sheet 270, and the heat inside the heat conduction support 260 is transferred to the heat transfer portion 261, and the outer peripheral wall of the pot body 230 is heated by the heat transfer portion 261, thereby further improving the heating rate of the herbal paste in the pot body 230, and then enhancing the atomization efficiency. There is no need to configure a heating wire arranged around the outer peripheral wall of the pot body 230, reducing the cost.
[0046] In addition, in this embodiment, the outer peripheral wall of the pot body 230 is cylindrical, the heat transfer portion 261 is an arc-shaped plate matching the outer peripheral wall of the pot body 230, and a plurality of the arc-shaped plates are distributed at intervals around the circumferential direction of the pot body 230. The upper end of the arc-shaped plate extends to the upper end of the pot body 230 and elastically contacts the outer peripheral wall of the pot body 230, which is beneficial to better fitting the pot body 230 to transfer heat efficiently.
[0047] It should be noted that the pot body 230 is made of quartz material, and the heat conduction support 260 is made of metal material, such as aluminum or iron. Among them, the insulating heat conduction sheet 270 is made of ceramic material. Ceramic has insulating heat property and good heat conductivity, avoiding the occurrence of electric conduction between the heating wire and the heat conduction support 260.
[0048] In this embodiment, the exhaust smoke pipe 210 and the air supply pipe 220 are of an integral structure. The air supply pipe 220 has a spiral channel arranged spirally downward around the central axis of the exhaust smoke pipe 210. The upper end of the spiral channel communicates with the first air inlet hole 506, and the lower end of the spiral channel communicates with the inner cavity of the pot body 230. When external gas is input downward into the pot body 230 through the spiral channel, it flows spirally downward along the inner peripheral wall of the pot body 230. The conical bulge 240 is conducive to the formed mist flowing spirally upward around the outer peripheral wall of the bulge 240 and towards the central axis of the bulge 240, thereby increasing the flow rate of the mist.

For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0050] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
