Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to a condensate recovery device. Background Technology

[0002] Nebulizers, widely used in daily life and healthcare, mainly fall into two categories: cold atomization and hot atomization. Cold atomization typically uses ultrasonic vibration to break down liquids into tiny droplets; hot atomization, commonly found in electronic cigarette atomizers and heated aromatherapy devices, uses heating elements to heat and evaporate the liquid, forming an inhalable aerosol. Although the two types of devices differ in their atomization methods and usage scenarios, both inevitably produce condensate after atomization.

[0003] In existing technologies, whether ultrasonic cold atomization or heating-based atomization, partial condensation of the aerosol is inevitable in the air delivery path. When the airflow encounters a cooler internal structural surface, the droplets condense into liquid and adhere to the channel walls. Over long-term use, the condensate produced by atomization accumulates on the inner walls of the housing, the air outlet, and the air delivery pipes, and is eventually inhaled into the mouth with the airflow. This not only causes significant discomfort for the user and affects the product experience, but also potentially poses hygiene and safety hazards. For example, accumulated condensate can cause backflow, leakage, and odor generation, and may even enter the heating area under certain conditions, posing a potential risk.

[0004] Currently, most atomizing devices on the market lack effective condensate separation and recovery mechanisms. Condensate easily mixes with the airflow and enters the inlet, tending to accumulate inside the device or flow backward along the air path. Especially at the air outlet, condensate buildup can easily cause liquid splashing at the inlet, severely impacting the user experience. Utility Model Content

[0005] The technical problem to be solved by this invention is to address the issue that condensate easily mixes with airflow and is sucked into the mouth, thus affecting the user experience.

[0006] To solve the above-mentioned technical problems, this utility model provides a condensate recovery device, comprising: a shell, wherein the shell has an installation cavity, and the top and bottom of the installation cavity are respectively provided with an air outlet and an air guide port; a return pipe wall, wherein a first port of the return pipe wall is connected to the air outlet, and a second port of the return pipe wall is located in the installation cavity, and the diameter of the return pipe wall gradually increases from bottom to top; an inner shell, wherein the inner shell is disposed in the installation cavity, and a gap channel is provided between the inner shell and the outer shell, and an airflow channel is provided inside the inner shell, wherein the two ends of the airflow channel are respectively corresponding to the second port of the return pipe wall and the air guide port; and an air guide pipe, wherein the air guide pipe is connected to the air guide port, and the second end of the air guide pipe is located in the installation cavity, and the air guide pipe is located below the airflow channel.

[0007] Furthermore, the inner shell has multiple ventilation holes on its side, with each ventilation hole connected to the airflow channel and the gap channel at both ends, and the multiple ventilation holes are arranged at equal intervals along the direction from the bottom of the inner shell to the top of the inner shell.

[0008] Furthermore, the inner shell includes a tube and a baffle. The tube is detachably mounted on the baffle, which is located within the mounting cavity. The air guide tube is located below the baffle, and the airflow channel is located within the tube and extends through the baffle. Multiple air vents are located on the side of the tube.

[0009] Furthermore, the inner shell also includes two partitions, which are respectively disposed at both ends of the airflow channel.

[0010] Furthermore, the bottom of the tube body is provided with an installation groove, and the baffle is provided with a protrusion that matches the installation groove.

[0011] Furthermore, the outer casing includes a housing and a base, the housing is disposed on the base, the housing and the base enclose the mounting cavity, the air inlet is disposed on the base, and the air outlet is disposed on the top of the housing.

[0012] Furthermore, the base is provided with a liquid accumulation groove, which is located below the gap channel.

[0013] Furthermore, it also includes a liquid-absorbing carrier disposed within the liquid accumulation groove, wherein the height of the top surface of the liquid-absorbing carrier is lower than the height of the second end of the air guide tube.

[0014] Furthermore, it also includes an extension tube, which is connected to a second port of the return pipe wall and is located above the airflow channel.

[0015] Furthermore, the air outlet is a flat air outlet, and the return pipe wall is a flat pipe wall.

[0016] Compared with the prior art, the condensate recovery device provided in this embodiment of the utility model has the following advantages: By setting a return pipe wall with a diameter that gradually increases from bottom to top at the air outlet of the outer shell, the atomized gas entering the airflow channel of the inner shell through the air guide pipe is blocked by the gradually expanding pipe wall during its upward flow. This effectively prevents the condensate carried by the atomized gas from rising along the inner wall of the outer shell to the air outlet and being sucked into the inlet. The blocked condensate flows along the inner wall of the outer shell into the gap channel between the inner and outer shells, realizing the physical separation of the atomized gas channel and the condensate return channel. This avoids the accumulation, retention, or leakage of liquid inside the device, and enables centralized recovery at the bottom of the outer shell. Furthermore, the second end of the air guide pipe is located inside the mounting cavity, making the second end of the air guide pipe higher than the bottom of the outer shell, preventing the recovered condensate from flowing back into the atomized gas path through the air guide port. This effectively solves the problems of condensate being easily sucked into the inlet, poor user experience, and difficulty in completely recovering condensate in existing atomizing devices, significantly improving the comfort of the atomizing device.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope. It should be noted that, unless otherwise specifically stated, the relative arrangement and numerical values ​​of the components and steps described in these examples do not limit the scope of this utility model.

[0020] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0021] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0022] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0024] like Figures 1 to 7 As shown in the figure, this utility model discloses a condensate recovery device, including: a shell 1, the shell 1 having an installation cavity 101, the top and bottom of the installation cavity 101 having an outlet 102 and an outlet 103 respectively; a return pipe wall 2, the first port of the return pipe wall 2 being connected to the outlet 102, the second port of the return pipe wall 2 being located inside the installation cavity 101, and the diameter of the return pipe wall 2 gradually increasing from bottom to top; an inner shell 3, the inner shell 3 being disposed inside the installation cavity 101, a gap channel 302 being provided between the inner shell 3 and the shell 1, and an airflow channel 301 being provided inside the inner shell 3, the two ends of the airflow channel 301 being respectively corresponding to the second port of the return pipe wall 2 and the outlet 103; and an air guide pipe 4, the air guide pipe 4 being connected to the outlet 103, the second end of the air guide pipe 4 being located inside the installation cavity 101, and the air guide pipe 4 being located below the airflow channel 301.

[0025] The condensate recovery device of this application, by setting a return pipe wall 2 with a gradually increasing diameter from bottom to top at the air outlet 102 of the outer shell 1, obstructs the upward flow of atomized gas entering the airflow channel 301 of the inner shell 3 through the air guide pipe 4. This effectively prevents the condensate carried by the atomized gas from rising along the inner wall of the outer shell 1 to the air outlet 102 and being sucked into the inlet. The blocked condensate flows along the inner wall of the outer shell 1 into the gap channel 302 between the inner shell 3 and the outer shell 1, realizing the physical separation of the atomized gas channel and the condensate return channel. This avoids the accumulation, retention, or leakage of liquid inside the device and enables centralized recovery at the bottom of the outer shell 1. Furthermore, the second end of the air guide pipe 4 is located inside the mounting cavity 101, making the second end of the air guide pipe 4 higher than the bottom of the outer shell 1, preventing the recovered condensate from flowing back into the atomized gas path through the air guide port 103. This effectively solves the problems of condensate being easily sucked into the inlet, poor user experience, and difficulty in completely recovering condensate in existing atomizing devices, significantly improving the comfort of the atomizing device.

[0026] like Figure 2 , Figure 3 and Figure 5 As shown, in an optional embodiment of the utility model, the inner shell 3 has a plurality of ventilation holes 303 on its side. The two ends of the ventilation holes 303 are connected to the airflow channel 301 and the gap channel 302 respectively. The plurality of ventilation holes 303 are arranged at equal intervals along the bottom of the inner shell 3 toward the top of the inner shell 3.

[0027] By providing multiple equidistant vent holes 303 on the side of the inner shell 3, arranged from bottom to top, with their ends connected to the airflow channel 301 and the gap channel 302 respectively, the atomized gas in the airflow channel 301 can release local pressure at different heights and achieve micro-gas-liquid separation as it passes upward. Simultaneously, condensed droplets adhering to the inner wall of the inner shell 3 or in the airflow can enter the gap channel 302 through the vent holes 303 under the influence of gravity and airflow disturbance, further improving the separation efficiency of the condensate. The porous, layered structure allows the condensate to be guided to the gap channel 302 immediately after formation, preventing its accumulation in the airflow channel 301, reducing the risk of backflow, and maintaining a smooth and stable gas path, effectively improving the separation efficiency and reliability of the entire condensate recovery device.

[0028] like Figure 5 , Figure 6 and Figure 7 As shown, in an optional embodiment of the utility model, the inner shell 3 includes a tube body 31 and a baffle 32. The tube body 31 is detachably mounted on the baffle 32. The baffle 32 is mounted in the mounting cavity 101. The air guide tube 4 is located below the baffle 32. The airflow channel 301 is mounted in the tube body 31 and passes through the baffle 32. Multiple air vents 303 are mounted on the side of the tube body 31.

[0029] By configuring the inner shell 3 to include a detachable tube 31 and a baffle 32 fixed within the mounting cavity 101, the airflow channel 301 is formed by the tube 31 penetrating the baffle 32. This not only facilitates assembly and maintenance but also allows for the disassembly, cleaning, or replacement of the tube 31 when needed, preventing blockages or hygiene hazards caused by condensate and droplet residues after long-term use. The baffle 32 divides the mounting cavity 101 into upper and lower sections, with the air guide pipe 4 located below the baffle 32 and the airflow channel 301 located inside the baffle 32 and the tube 31 above it, thus forming a clearer and more stable gas-liquid separation path. Ventilation holes 303 are arranged on the side of the tube 31, allowing condensate to quickly enter the gap channel 302 after forming on or inside the tube 31, improving condensate diversion efficiency. The overall structure not only enhances the maintainability and service life of the device but also makes the airflow channel 301 more independent and unobstructed, further improving the reliability of condensate separation and recovery.

[0030] Specifically, the inner shell 3 can be filled with a formulated substance, which can be in a solid, liquid, or semi-solid state. The components of the formulated substance can be fragrances, nicotine, pharmaceuticals, or health products, etc. Both the inner shell 3 and the baffle 32 are made of medical-grade, food-grade, environmentally friendly stainless steel. The baffle 32 is used to fix the formulated substance and prevent it from leaking out of the inner shell 3. The tube 31 can be attached to the baffle 32 using clips, slots, or fixing straps.

[0031] Specifically, the top of the housing 11 is the suction nozzle, and the air outlet 102 is located on the output end of the suction nozzle. The housing 11 is made of medical-grade food-grade environmentally friendly PCTG material.

[0032] like Figure 5 and Figure 7 As shown, in an optional embodiment of the utility model, the inner shell 3 further includes two partitions 33, which are respectively disposed at both ends of the airflow channel 301.

[0033] By installing two baffles 33 at both ends of the airflow channel 301, the atomized gas entering the airflow channel 301 can be initially filtered and the airflow stabilized. This prevents larger droplets or impurities from entering the channel, thereby reducing their condensation and accumulation within the channel and further reducing the risk of blockage. The baffles 33 also make the airflow entering the channel more uniform and stable, which is beneficial to the subsequent gas-liquid separation process, while ensuring that the separation efficiency of the vent 303 is not affected by large droplets. The overall structure effectively improves the airflow quality and internal cleanliness, enhancing the stability and reliability of the condensate recovery device during long-term use.

[0034] Specifically, the two partition nets 33 are integrally formed with the pipe body 31 and the baffle 32, respectively.

[0035] like Figure 5 and Figure 7 As shown, in an optional embodiment of the utility model, the bottom of the tube body 31 is provided with an installation groove 304, and the baffle 32 is provided with a protrusion 321 that is adapted to the installation groove 304.

[0036] By providing an installation groove 304 at the bottom of the pipe body 31 and a matching protrusion 321 on the baffle 32, the pipe body 31 can be securely installed on the baffle 32 by snap-fit ​​or limiting, thus achieving quick assembly and disassembly and reliable positioning. This structure ensures the coaxiality and sealing of the pipe body 31 in the airflow channel 301, avoiding airflow turbulence or reduced separation efficiency due to installation misalignment. It also allows users to easily remove the pipe body 31 for cleaning or replacement during maintenance, improving the maintainability of the device. Furthermore, the fit between the protrusion 321 and the installation groove 304 maintains connection stability during long-term use, preventing loosening and making the overall operation of the condensate recovery device more reliable and durable.

[0037] like Figure 1 , Figure 4 and Figure 7 As shown, in an optional embodiment of the utility model, the outer shell 1 includes a shell 11 and a base 12. The shell 11 is disposed on the base 12, and the shell 11 and the base 12 enclose each other to form an installation cavity 101. The air inlet 103 is disposed on the base 12, and the air outlet 102 is disposed on the top of the shell 11.

[0038] By configuring the outer casing 1 as an enclosure 101 formed by the combination of the casing 11 and the base 12, and placing the air inlet 103 on the base 12 and the air outlet 102 on the top of the casing 11, the overall airflow path of the device is made clearer and smoother, forming a natural airflow direction from bottom to top, which is beneficial for the rising of atomized gas and the sinking and separation of condensate. At the same time, the structure of the base 12 facilitates the centralized collection of settled condensate, reducing liquid retention on the inner wall of the casing 11; the separate design of the casing 11 and the base 12 facilitates assembly and condensate recovery, allowing for quick disassembly and cleaning of internal components without damaging the overall structure. This layout not only improves the gas-liquid separation efficiency but also enhances the structural stability and ease of use of the device, making the condensate recovery process more thorough and reliable. Specifically, the inner wall of the casing 11 is provided with vertically extending drainage grooves to help the condensate flow along the inner wall of the casing 11 to the base 12 for collection.

[0039] like Figure 2 and Figure 3 As shown, in an optional embodiment of the utility model, the base 12 is provided with a liquid accumulation groove 104, which is located below the gap channel 302.

[0040] By providing a condensate collection groove 104 on the base 12 below the gap channel 302, the condensate that flows through the vent hole 303 and the inner wall of the outer shell 1 to the gap channel 302 can naturally collect in the condensate collection groove 104 under the action of gravity, thus forming an independent and clearly defined condensate collection area and preventing the condensate from spreading disorderly or overflowing at the bottom. This structure not only improves the concentration and thoroughness of condensate recovery and reduces the possibility of internal residue and secondary evaporation, but also facilitates the user's observation, discharge, or cleaning of the accumulated condensate. At the same time, the condensate collection groove 104 is isolated from the airflow channel 301, ensuring that the air path remains dry and unobstructed at all times, and that the airflow stability is not affected by condensate accumulation, thus significantly improving the safety, reliability, and hygiene performance of the entire condensate recovery device.

[0041] like Figure 2 and Figure 3 As shown, in an optional embodiment of the utility model, a liquid-absorbing carrier 5 is also included. The liquid-absorbing carrier 5 is disposed in the liquid accumulation groove 104, and the height of the top surface of the liquid-absorbing carrier 5 is lower than the height of the second end of the air guide tube 4.

[0042] By installing a liquid-absorbing carrier 5 within the liquid accumulation groove 104, the condensate collected in the groove can be quickly absorbed and retained within the carrier 5, preventing the liquid from flowing freely, sloshing around, or overflowing during equipment movement. The liquid-absorbing carrier 5 significantly improves the storage stability of the condensate, reduces the risk of odor from liquid evaporation, and lowers the cleaning frequency, allowing users to perform maintenance simply by periodically replacing the carrier 5. Furthermore, the carrier 5 further prevents condensate from flowing back into the gas path area, strengthening the effective isolation of the gas-liquid channels and ensuring the entire condensate recovery system maintains higher hygiene, safety, and reliability during long-term use.

[0043] like Figure 2 and Figure 3 As shown, in an optional embodiment of the utility model, an extension tube 6 is also included. The extension tube 6 is connected to the second port of the return tube wall 2 and is located above the airflow channel 301.

[0044] By installing an extension pipe 6 connected to the second port of the return pipe wall 2 and arranging the extension pipe 6 above the airflow channel 301, the atomized gas entering the airflow channel 301 of the inner shell 3 from the gas guide pipe 4 has a longer path to contact the return pipe wall 2 during its ascent. This increases the chance of condensate settling on the pipe wall and effectively prevents condensate from entering the outlet 102 with the airflow. The extension pipe 6 not only optimizes the gas-liquid separation effect and improves the condensate interception and recovery efficiency, but also ensures the unobstructed flow of the airflow channel 301, reduces the risk of droplet backflow, and enables the entire device to recover condensate more thoroughly and safely during use, improving the user experience and equipment reliability. Specifically, the extension pipe 6 is integrally formed with the return pipe wall 2.

[0045] like Figure 1 and Figure 7 As shown, in an optional embodiment of the utility model, the air outlet 102 is a flat air outlet 102, and the return pipe wall 2 is a flat pipe wall.

[0046] By designing the outlet 102 as a flat shape and using a corresponding flat return pipe wall 2, the atomized gas is evenly distributed along the flat direction during its upward movement, increasing the gas-liquid contact area and thus enhancing the sedimentation and retention effect of the condensate on the return pipe wall 2. The flat structure effectively reduces airflow turbulence, maintains the stability of the airflow channel 301, and ensures that the condensate flows smoothly along the inner wall of the outer shell 1 into the gap channel 302 for recovery, further reducing the risk of liquid backflow. This design not only improves the condensate separation efficiency and recovery thoroughness but also optimizes the uniformity of the airflow and the exhaust performance of the outlet 102, improving the overall user comfort and reliability of the device.

[0047] The condensate recovery device of this invention forms an installation cavity 101 inside the outer shell 1. The top of the installation cavity 101 has an outlet 102, and the bottom has a guide port 103. A return pipe wall 2 is provided at the outlet 102. The upper end of the return pipe wall 2 communicates with the outlet 102, and the lower end is located inside the installation cavity 101. The diameter of the return pipe wall 2 gradually increases from bottom to top, allowing the condensate adhering to the airflow to settle along the pipe wall and be blocked, preventing it from entering the outlet 102. The inner shell 3 is disposed inside the installation cavity 101, forming a gap channel 302 between the inner shell 3 and the outer shell 1. An airflow channel 301 is provided inside the inner shell 3. The two ends of the airflow channel 301 correspond to the upper end of the return pipe wall 2 and the guide port 103, respectively, allowing atomized gas to enter the airflow channel 301 from the guide pipe 4 and rise along the channel. The condensate then converges to the bottom along the gap channel 302 between the inner shell 3 and the outer shell 1. The air guide tube 4 is connected to the air guide port 103. The upper end of the air guide tube 4 is located inside the mounting cavity 101 and below the airflow channel 301 to ensure smooth airflow and prevent condensate from flowing back into the air path, thereby realizing the functions of gas-liquid separation and effective condensate recovery.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
