Description

Technical Field

[0001] This utility model relates to the field of fumigation technology, and in particular to a fumigation device for cooling and inhaling. Background Technology

[0002] A fumigation device generally consists of a main body and an atomizer. The atomizer contains a heating pot for storing herbal ingredients. Heating the pot atomizes the ingredients, producing mist. When the user inhales the mist, it enters the mouthpiece and is inhaled. Simultaneously, external air enters the pot to aid in the combustion of the herbal ingredients and to achieve pressure equilibrium. However, some herbal ingredients produce high-temperature mist. To prevent burns to the user's throat, current methods involve passing the mist through a water-filled container. The mist bubbles at the water surface before exiting the mouthpiece. Passing through water filters out some of the herbal components, resulting in less effective fumigation.

[0003] In addition, when the herbal paste in the heating pot is heated and turns into a liquid, it boils and then forms mist. The heating pot used to hold the herbal paste is usually a flat-bottomed pot, and the middle part of the heating pot heats up more slowly, resulting in a lower efficiency in producing mist. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the purposes of this utility model is to provide a cooling inhalation fumigator that uses an extended exhaust heat exchange pipe to cool the mist to avoid scalding the user's respiratory tract, and also to avoid losing the effective components of the mist, thus ensuring the purity of the flavor of the mist produced when burning herbal materials.

[0005] A cooling fumigation device according to an embodiment of the present invention includes: a fumigation device body, a heating pot assembly, and a suction nozzle assembly. A heat exchange container is connected between the heating pot assembly and the suction nozzle assembly. The heat exchange container is provided with an exhaust heat exchange pipe that is reciprocated by bending or coiling. The two ends of the exhaust heat exchange pipe are respectively connected to the exhaust end of the heating pot assembly and the suction nozzle assembly. A cavity is defined between the exhaust heat exchange pipe 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 to the cavity, and the air outlet connects the cavity to the air inlet of the heating pot assembly.

[0006] A cooling inhalation fumigator according to an embodiment of the present invention has at least the following beneficial effects:

[0007] When the user inhales through the mouthpiece assembly, the high-temperature mist generated in the heating pot assembly passes through the reciprocatingly bent or coiled exhaust heat exchange pipe inside the heat exchange container. The exhaust heat exchange pipe exchanges heat with the medium in the cavity and then exits from the mouthpiece assembly. At the same time, external gas enters the heating pot assembly after passing through the air inlet, cavity, and air outlet in sequence. When the external gas passes through the cavity, it exchanges heat with the mist in the exhaust heat exchange pipe, which helps to lower the temperature of the mist, achieving a cooling effect for inhalation and avoiding burns to the user's respiratory tract. The external gas itself achieves a temperature rise, which is conducive to the combustion of the herbal materials. It also avoids the traditional method of expelling the mist through water, which would result in the loss of the effective components of the mist and ensure the purity of the flavor of the mist produced when burning the herbal materials.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Reference Figures 1 to 4 This utility model discloses a cooling fumigation device, comprising: a fumigation device body 100, a heating pot assembly 200, and a suction nozzle assembly 300. A heat exchange container 400 is connected between the heating pot assembly 200 and the suction nozzle assembly 300. The heat exchange container 400 is provided with an exhaust heat exchange pipe 410 that is reciprocally bent or reciprocally coiled. The two ends of the exhaust heat exchange pipe 410 are respectively connected to the exhaust end of the heating pot assembly 200 and the suction nozzle assembly 300. A cavity 420 is defined between the exhaust heat exchange pipe 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 to the cavity 420, and the air outlet 440 connects the cavity 420 and the air inlet of the heating pot assembly 200.

[0034] When a user inhales through the mouthpiece assembly 300, the high-temperature mist generated in the heating pot assembly 200 passes through the reciprocatingly bent or coiled exhaust heat exchange pipe 410 within the heat exchange container 400. The exhaust heat exchange pipe 410 exchanges heat with the medium in the cavity 420 and then exits from the mouthpiece assembly 300. Simultaneously, external gas enters the heating pot assembly 200 after passing through the air inlet 430, the cavity 420, and the air outlet 440. When the external gas passes through the cavity 420, it exchanges heat with the mist in the exhaust heat exchange pipe 410, which helps to lower the temperature of the mist, achieving a cooling effect for inhalation and preventing burns to the user's respiratory tract. The external gas itself achieves a temperature rise, which is conducive to the combustion of the herbal materials and avoids the loss of effective components in the mist caused by the traditional method of passing the mist through water and exhausting it, ensuring the purity of the flavor of the mist produced when burning the herbal materials. It is understandable that water can be injected into the cavity 420 to increase the cooling rate of the mist in the exhaust heat exchange tube 410. Since the mist runs in the exhaust heat exchange tube 410, there will be no problem of loss of the effective components of the mist.

[0035] See Figure 2 and Figure 3In some embodiments of this utility model, the heat exchange container 400 is generally cylindrical, and the exhaust heat exchange pipe 410 is spirally wound upward around the axial direction of the heat exchange container 400. A first exhaust pipe 450 and a second exhaust pipe 460 are protruding from the upper end face of the heat exchange container 400. The first exhaust pipe 450 connects one end of the exhaust heat exchange pipe 410 to the exhaust end of the heating pot assembly 200, and the second exhaust pipe 460 connects the other end of the exhaust heat exchange pipe 410 to the suction nozzle assembly 300. It can be understood that when the mist generated in the heating pot assembly 200 is discharged, it enters the exhaust heat exchange pipe 410 through the first exhaust pipe 450. After spiraling upward or downward along the exhaust heat exchange pipe 410, the mist enters the suction nozzle assembly 300 through the second exhaust pipe 460 and is then inhaled by the user. The exhaust heat exchange pipe 410 with the above structure helps to fully extend the travel distance of the mist from the heating pot assembly 200 to the suction nozzle assembly 300, thereby fully exchanging heat with the medium in the cavity 420 and achieving a better cooling effect.

[0036] See Figure 2 , Figure 3 and Figure 5 In some embodiments of this utility model, the air inlet 430 and the air outlet 440 are both located on the upper 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 and exhaust ends of the heating pot assembly 200 are both located on its upper end. The upper end of the heating pot assembly 200 and the upper end of the heat exchange container 400 are connected by a mounting cover 500. The mounting cover 500 is provided with a first air inlet channel 510 that connects the external environment with the air inlet 430, a second air inlet channel 520 that connects the air outlet 440 and the air inlet end of the heating pot assembly 200, a first exhaust channel 530 that connects the exhaust end of the heating pot assembly 200 and the first exhaust pipe 450, and a second exhaust channel 540 that connects the second exhaust pipe 460 and the suction nozzle assembly 300. With the above structure, while the upper end of the heating pot assembly 200 and the upper end of the heat exchange container 400 are connected by the mounting cover 500, the air intake path of the external gas and the exhaust path of the mist are directly connected, which greatly simplifies the construction and assembly process of the fumigator.

[0037] See Figure 2 and Figure 4In some embodiments of this utility model, the mounting cover 500 is made of silicone material. The mounting cover 500 has two glass tubes that respectively constitute the first exhaust channel 530 and the second exhaust channel 540. The suction nozzle assembly 300, the first exhaust pipe 450, and the second exhaust pipe 460 are all detachably and tightly fitted into the mounting cover 500. It is understood that when the suction nozzle assembly 300, the first exhaust pipe 450, and the second exhaust pipe 460 are inserted into the mounting cover 500, the silicone material of the mounting cover 500 helps ensure the airtightness between any two connected pipes and facilitates detachable installation for replacement or maintenance of the heat exchange container 400. Furthermore, the high-temperature mist is less likely to cross-contaminate when passing through the two glass tubes serving as the first exhaust channel 530 and the second exhaust channel 540, ensuring the purity of the aroma of the mist produced when burning herbal materials.

[0038] See Figure 4 and Figure 5 In some embodiments of this utility model, the mounting cover 500 includes a bottom cover 501 and a top cover 502. The upper end of the bottom cover 501 is recessed downward to form a first recessed groove 503 with an upward opening. The top cover 502 closes the opening of the first recessed groove 503. A first exhaust hole 504 and a second exhaust hole 505 are provided through the two ends of the first recessed groove 503 in the vertical direction. The first exhaust channel 530 is connected between the first exhaust hole 504 and the second exhaust hole 505. The first recessed groove 503 is provided with a first exhaust hole 504 and a second exhaust hole 505 in the vertical direction. A first air inlet 506 and a second air inlet 507 are provided through the first smoke exhaust hole 504 and the second smoke exhaust hole 505. The heating pot assembly 200 has an exhaust pipe 210 and a gas supply pipe 220 located on the outer periphery of the exhaust pipe 210. The exhaust pipe 210 is inserted into the first smoke exhaust hole 504. The gas supply pipe 220 is connected to the first air inlet 506. The second air inlet 507 is connected to the air outlet 440. The second smoke exhaust hole 505 is connected to the first exhaust pipe 450.

[0039] It should be noted that if the first exhaust channel 530 and the second exhaust channel 540 were directly formed inside the mounting cover 500, the materials constituting the first exhaust channel 530 and the second exhaust channel 540 would be easily affected by the heat transfer of the high-temperature mist, producing an odor and affecting the user experience. Therefore, the mounting cover 500 of the above structure adopts a bottom cover 501 and a top cover 502 assembled together, using the first recess 503 to accommodate the glass tube constituting the first exhaust channel 530. The two ends of the glass tube are connected to the first smoke vent 504 and the second smoke vent 505, thereby solving the problem of odor generated by the mist. In addition, the top cover 502 closes the opening of the first recess 503 so that the first air inlet 506 and the second air inlet 507 are directly connected. Since the temperature of the external gas before entering the heating pot assembly 200 is low, the external gas passes through the cavity 420 and then sequentially through the air outlet 440, the second air inlet 507, the first air inlet 506, and the air supply pipe 220, thereby reaching the heating pot assembly 200 to assist in the combustion of the herbal materials.

[0040] See Figure 2 and Figure 3 In some embodiments of this utility model, there is a gap between the exhaust heat exchange pipe 410 and the inner peripheral wall of the heat exchange container 400. The heat exchange container 400 is provided with an air inlet extension pipe 600 that passes downward from the hollow position of the exhaust heat exchange pipe 410. The upper end of the air inlet extension pipe 600 is connected to the air inlet 430, and the lower end of the air inlet extension pipe 600 extends to near the inner bottom surface of the heat exchange container 400. It should be noted that without the air inlet extension pipe 600, when external gas enters the cavity 420 from the air inlet 430, some of the gas may not have fully exchanged heat with the exhaust heat exchange pipe 410 before being directly discharged from the air outlet 440 into the heating pot assembly 200. The mist in the exhaust heat exchange pipe 410 is not sufficiently cooled, resulting in a high temperature when the mist reaches the mouthpiece assembly 300, which could easily burn the user's throat. The external gas itself also does not achieve sufficient temperature rise, which is not conducive to the combustion of the herbal materials, resulting in a waste of heat energy. Furthermore, the gas entering the cavity 420 is prone to generating a lot of turbulence, leading to a lot of noise. In the above embodiment, the lower end of the air inlet extension pipe 600 extends 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 fully contact and exchange heat with the exhaust heat exchange pipe 410, thereby solving the problems mentioned above. In addition, the intake extension pipe 600 passes downward through the hollow part of the exhaust heat exchange pipe 410. The spiral exhaust heat exchange pipe 410 generates heat radiation to the intake extension pipe 600 located in the middle, which also helps to increase the pipe wall temperature of the intake extension pipe 600.

[0041] See Figure 3 and Figure 4 In some embodiments of this utility model, the air inlet 430 is located in the middle of the upper end face of the heat exchange container 400, and two opposing exhaust holes 610 are horizontally arranged at the lower end of the air inlet extension pipe 600. Two air outlets 440 are arranged symmetrically about the center of the air outlets 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 opposing airflows, which are horizontally blown towards the inner peripheral wall of the heat exchange container 400, helping to quickly disperse into the cavity 420 and preventing excessive turbulence caused by the lower end of the air inlet extension pipe 600 blowing directly downwards towards the bottom wall of the heat exchange container 400. The position of the two air outlets 440 helps to increase the airflow rate at the air inlet end of the heating pot assembly 200.

[0042] In some embodiments of this 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 or quartz. Firstly, the glass or quartz material used in the heat exchange container 400, exhaust heat exchange pipe 410, and air inlet extension pipe 600 helps reduce the probability of cross-contamination of odors along their path, ensuring the purity of the aroma of the mist produced when burning herbal materials. Secondly, the integral structure of the heat exchange container 400, exhaust heat exchange pipe 410, and air inlet extension pipe 600 is conducive to achieving a lightweight effect, making the fumigator easier to hold and providing a better experience during prolonged use. Specifically, the exhaust heat exchanger tube 410 and the inlet extension tube 600 are first separately fired. Then, the exhaust heat exchanger tube 410 and the inlet extension tube 600 are positioned and fired to obtain the heat exchange container 400. The integrated structure composed of the heat exchange container 400, the exhaust heat exchanger tube 410, and the inlet extension tube 600 is not only inexpensive but also has a stable connection and facilitates rapid heat dissipation. Of course, in other embodiments, the heat exchange container 400, the exhaust heat exchanger tube 410, and the inlet extension tube 600 can also be made of thin-walled stainless steel sheets and then welded together to form an integrated structure. However, compared to the integrated structure made of glass or quartz materials, the cost and manufacturing difficulty are higher.

[0043] See Figures 6 to 8In some embodiments of this utility model, the heating pot assembly 200 includes a pot body 230. The inner bottom wall of the pot body 230 has a protruding bulge portion 240 located in the middle of the inner cavity of the pot body 230. The bulge portion 240 has a downward-facing receiving cavity 241. 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 disposed 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. The heating pot assembly 200 with the above structure has a bulge 240 protruding from the inner bottom wall of the pot body 230. The heating element 250 contacts the outer bottom wall of the pot body 230 and the auxiliary heating element contacts the inner wall of the corresponding accommodating cavity 241 of the bulge 240. This increases the contact area between the bottom of the pot body 230 and the herbal paste. Moreover, the heating bulge 240 is located in the middle of the inner cavity of the pot body 230, which is conducive to the rapid heating of the herbal paste located in the middle of the pot body 230, achieving a rapid and uniform heating effect, thereby improving the atomization efficiency.

[0044] Specifically, the bulge 240 is formed by the upward protrusion of the bottom wall of the pot body 230. The thickness of the bulge 240 is the same as the thickness of the bottom wall of the pot body 230, meaning that the pot body 230 and the bulge 240 are an integral structure. This simplifies the production process and reduces manufacturing costs. Furthermore, since the thickness of the bulge 240 is the same as the thickness of the bottom wall of the pot body 230, it ensures uniform heating of both the bottom wall of the pot body 230 and the bulge 240, preventing insufficient heating of the bulge 240 and thus ensuring the herbal paste melts. It is conceivable that the pot body 230 and the bulge 240 can be manufactured using methods such as integral casting, powder metallurgy, or machining. Alternatively, the bulge 240 can also be formed on the bottom wall of the pot body 230 by stamping, in which case the thickness of the bulge 240 is slightly smaller than the thickness of the bottom wall of the pot body 230.

[0045] See Figure 6 , Figure 7 and Figure 8In some embodiments of this utility model, the bulge portion 240 is generally conical in shape, gradually narrowing from bottom to top. After the herbal paste in contact with the surface of the bulge portion 240 melts into a liquid, it can flow along the slope of the bulge portion 240 to the inner bottom wall of the pot body 230 for further heating, which facilitates rapid atomization of the liquid into mist. The heating element 250 is a heating wire, which includes a spiral coil portion 251 and a spiral tower portion 252 wound together. The spiral coil 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 section 252 is the aforementioned auxiliary heating section. The heating element 250 of this structure is very simple and inexpensive, and provides good heating uniformity to various positions at the bottom of the pot body 230. A heat-conducting support 260 is provided below the pot body 230. An insulating heat-conducting sheet 270 is sandwiched between the heat-conducting support 260 and the spiral disc section 251. The heat-conducting support 260 has a heat transfer section 261 that contacts the outer peripheral wall of the pot body 230. Both the heat-conducting support 260 and the insulating heat-conducting sheet 270 are provided with through holes opposite to the spiral tower section 252. One end of the heating wire can pass through the through holes downwards. The spiral disc 251 transfers heat to the heat-conducting bracket 260 through the insulating heat-conducting sheet 270. The heat inside the heat-conducting bracket 260 is transferred to the heat transfer part 261, which heats the outer peripheral wall of the pot body 230, thereby further improving the heating rate of the herbal paste inside the pot body 230 and thus improving the atomization efficiency. There is no need to configure the heating wire around the outer peripheral wall of the pot body 230, thus reducing costs.

[0046] Furthermore, in this embodiment, the outer peripheral wall of the pot body 230 is cylindrical, and the heat transfer part 261 is an arc-shaped plate that cooperates with the outer peripheral wall of the pot body 230. A plurality of arc-shaped plates are distributed circumferentially around 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 fit the pot body 230 to efficiently transfer heat.

[0047] It should be noted that the pot body 230 is made of quartz material, the heat-conducting bracket 260 is made of metal material, such as aluminum or iron, and the insulating heat-conducting sheet 270 is made of ceramic material. Ceramic has insulating thermal properties and good thermal conductivity, which prevents electrical conductivity between the heating wire and the heat-conducting bracket 260.

[0048] In this embodiment, the exhaust pipe 210 and the air supply pipe 220 are an integral structure. The air supply pipe 220 has a spiral channel that spirals downward around the central axis of the exhaust pipe 210. The upper end of the spiral channel is connected to the first air inlet 506, and the lower end of the spiral channel is connected to the inner cavity of the pot body 230. When the external gas is input into the pot body 230 from the spiral channel, it spirals downward along the inner peripheral wall of the pot body 230. The conical bulge 240 facilitates the formation of mist that spirals upward around the outer peripheral wall of the bulge 240 and flows toward the central axis of the bulge 240, thereby increasing the flow rate of the mist.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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, they should be considered to be within the scope of this specification.

[0050] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
