Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and in particular to a hot drying apparatus. Background Technology

[0002] A heat drying device is a device that uses hot air or heating elements to heat materials. It is often used to heat and cure hot melt adhesive powder on heat transfer film so that it is evenly attached to the pattern of the heat transfer film to form a transferable layer.

[0003] During the heat drying process, the chemical reagents in the materials may volatilize and cause contamination. Taking a heat transfer film to be cured as an example, the ink layer on the heat transfer film often emits glycerol vapor during the heat drying process. After the glycerol vapor comes into contact with the wall of the heat drying device, it will gradually condense into glycerol droplets. These glycerol droplets may drip onto the heat transfer film and cause contamination. Utility Model Content

[0004] To solve the above-mentioned technical problems, embodiments of this application provide a hot drying device, which includes a first body and a second body, the first body and the second body being arranged to form a hot drying cavity; the first body includes a base and a heating component, the heating component being disposed on the base and used to heat the hot drying cavity;

[0005] The second body includes a casing and components disposed within the casing:

[0006] The air passage connects the heated oven cavity to the external environment.

[0007] A fan is used to push gas into an airflow within the air passage.

[0008] The condensing component has a condensing chamber, which is connected to the heating chamber and the external environment through an air passage. It is used to condense part of the airflow into liquid and to collect the liquid. The projections of the condensing component and the heating component on the casing do not overlap or only partially overlap.

[0009] The beneficial effects of the hot drying apparatus provided in this application are:

[0010] This application utilizes a fan to generate airflow from the heating chamber to the external environment, allowing any chemical reagent vapors present in the heating chamber to flow out with the airflow, preventing the chemical reagent vapors from condensing into droplets on the chamber walls. Furthermore, by installing a condensing assembly on the casing and connecting the heating chamber, the condensing chamber of the condensing assembly, and the external environment through an air duct in the casing, the airflow exiting the heating chamber can flow into the condensing chamber through the air duct. Consequently, any chemical reagent vapors present in the airflow will condense into liquid within the condensing chamber and be contained there, preventing the chemical reagent vapors from being released into the external environment and causing pollution. Finally, by ensuring that the projections of the condensing assembly and the heating assembly on the casing do not overlap or only partially overlap, this application reduces the temperature impact on the condensing assembly from the heating assembly, thereby improving condensation efficiency.

[0033] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0035] This application provides a thermal drying apparatus. The thermal drying apparatus can be used to thermally dry a heat transfer film to cure it. Of course, the thermal drying apparatus can also be applied to other scenarios; the following description mainly uses this scenario as an example. Please refer to... Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural schematic diagram of the hot drying apparatus provided in some embodiments of this application. Figure 2 yes Figure 1 An exploded view of the hot drying apparatus in the embodiment.

[0036] The heating apparatus 10 includes a first body 11 and a second body 12, which cooperate to achieve the heating function. The first body 11 may include a heating component 100. In some embodiments, the first body 11 and the second body 12 are at least partially separable. In other words, the connection between the first body 11 and the second body 12 can be a completely separable connection or a partially separable connection.

[0037] For example, the first body 11 can be completely separably connected to the second body 12 by means of, but not limited to, fastening, snapping, magnetic attraction, or stacking under gravity. During the heat treatment process in the heat treatment device 10, the first body 11 and the second body 12 are connected. After heat treatment is completed and before heat treatment begins, the first body 11 and the second body 12 can be connected or separated. For example, when the user needs to place the heat transfer film into the heat treatment device 10 or remove the heat transfer film from the heat treatment device 10, the first body 11 and the second body 12 can be separated. Alternatively, when the heat treatment device 10 has just completed heat treatment, the user can keep the first body 11 and the second body 12 connected for a period of time before controlling their separation.

[0038] The first body 11 can also be partially separable from the second body 12 through methods such as, but not limited to, hinges or sliding connections. Similarly, the user can adjust the relative positions of the first body 11 and the second body 12 as needed. Taking the hinged connection of the first body 11 and the second body 12 as an example, the user can control the second body 12 to rotate forward relative to the first body 11, so that the first body 11 and the second body 12 are partially separated. At this time, the hinged part of the first body 11 and the second body 12 is still in a connected state. Alternatively, the user can control the second body 12 to rotate in the opposite direction relative to the first body 11, so that the first body 11 and the second body 12 switch from a partially separated state to a connected state. In other embodiments, the first body 11 and the second body 12 can also be at least partially an integral structure. The following description mainly uses the hinged connection of the first body 11 and the second body 12 as an example.

[0039] In this design, the first body 11 is the lower part of the heating device 10 during normal operation, while the second body 12 is the upper part. The first body 11 can be supported on an operating surface, such as a table, countertop, or floor. The bottom of the first body 11 may be equipped with feet or other support structures. The second body 12 may be equipped with a handle 123 to facilitate user control of its movement.

[0040] Understandably, all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0041] Please see Figures 2 to 4 , Figure 3 yes Figure 1 A cross-sectional schematic diagram of the hot drying device in the embodiment. Figure 4 This is an exploded structural diagram of the first organism provided in some embodiments of this application.

[0042] In some embodiments, the first body 11 and the second body 12 may be configured to form a hot drying cavity 101. The first body 11 may include a heating assembly 100 for heating the hot drying cavity 101. It is understood that the first body 11 and the second body 12 are configured to form the hot drying cavity 101 when the hot drying device 10 is in normal operation, and when the first body 11 and the second body 12 are at least partially separated, the first body 11 and the second body 12 do not form the hot drying cavity 101.

[0043] The first body 11 may include a base 200, and the second body 12 may include a housing 300. The base 200 and the housing 300 are at least partially separable from each other to achieve a partially separable connection between the first body 11 and the second body 12. In other embodiments, the base 200 and the housing 300 may also be an integral structure. Both the housing 300 and the base 200 may be generally square, and the corners of both the base 200 and the housing 300 may be rounded. The housing 300 may be at least partially transparent or partially transparent to allow the user to observe the contents of the heating chamber 101 during the heating process.

[0044] The heating component 100 is mounted on the base 200. Optionally, the surface of the heating component 100 serves as part of the cavity wall of the hot drying chamber 101. The base 200 may have a mounting groove 201, in which the heating component 100 is positioned, such that the top of the heating component 100 is flush with, slightly lower than, or slightly higher than, the top of the base 200, achieving a semi-concealed installation of the heating component 100. The bottom of the housing 300 may also have a through hole communicating with the mounting groove 201, allowing the bottom of the heating component 100 to be exposed to the outside environment, thereby saving material on the housing 300 and reducing the manufacturing cost of the first body 11. In other embodiments, the surface of the heating component 100 may be connected to or spaced from the cavity wall of the hot drying chamber 101, without forming part of the cavity wall of the hot drying chamber 101.

[0045] Please see Figure 4 and Figure 5 , Figure 5 This is a cross-sectional structural diagram of a heating component provided in some embodiments of this application.

[0046] In some embodiments, the heating assembly 100 may include a heating plate 110 and a heating wire 120. The heating plate 110 forms the upper surface of the heating assembly 100, and the heating wire 120 is disposed at the bottom of the heating plate 110 and in contact with the heating plate 110. The surface of the heating plate 110 may constitute part of the cavity wall of the hot drying chamber 101. The heating wire 120 has a heating function and can heat the hot drying chamber 101 through the heating plate 110. The heating wire 120 may be designed, for example but not limited to, a bent shape or a mesh shape, to increase the contact area between the heating wire 120 and the heating plate 110. The heating wire 120 may be, but is not limited to, embedded in the bottom surface of the heating plate 110.

[0047] Optionally, the heating assembly 100 also includes a temperature sensor (not shown) to allow the heating device 10 to detect and control the surface temperature of the heating plate 110. The heating plate 110 can be made of metal, such as aluminum. The heating wire 120 and the heating plate 110 can be manufactured using an integral die-casting process. By utilizing the excellent thermal conductivity of metals such as aluminum and PID control in the program, precise control of the target surface temperature of the heating plate 110 can be achieved, which can improve the uniformity of the surface temperature of the heating plate 110. Specifically, the temperature difference between the surface temperature of the heating plate 110 and the set temperature can be controlled within 6 degrees Celsius.

[0048] The heating assembly 100 may further include a heat-insulating back plate 130 and a heat-insulating edge ring 140. The heat-insulating back plate 130 is disposed on the bottom side of the heating plate 110 and is stacked with the heating plate 110 to block the heat from the heating wire 120. The heat-insulating edge ring 140 is sleeved on the heating plate 110 to block the heat from the heating plate 110. The heat-insulating back plate 130 and the heat-insulating edge ring 140 can prevent the heat from the heating assembly 100 from being transferred to the base 200. The heat-insulating back plate 130 may overlap the base 200. The heating assembly 100 may further include heat-insulating cotton 150, which may be disposed between the heating plate 110 and the heat-insulating back plate 130 to prevent the heat from the heating plate 110 and the heating wire 120 from being transferred to the heat-insulating back plate 130, thereby improving the heating efficiency of the heating assembly. Understandably, components such as the heat insulation backplate 130, heat insulation edge ring 140, and heat insulation cotton 150 have limited heat blocking effect. This article does not limit them to blocking heat 100%. Their function of preventing heat transfer should be understood as having a low heat conduction efficiency.

[0049] In other embodiments, the heating assembly 100 may also be designed as other structures capable of heating the hot drying cavity 101, and is not limited to the design described above.

[0050] Please see Figures 6 to 8 , Figure 6 yes Figure 3 The diagram shows a partial cross-sectional view of the hot drying device. Figure 7 This is a three-dimensional structural schematic diagram of a limiting hinge provided in some embodiments of this application. Figure 8 yes Figure 7 An exploded view of the limiting hinge in the embodiment.

[0051] In some embodiments, the heat-drying device 10 may include a first hinge 131 and a second hinge 132, with the first hinge 131 and the second hinge 132 rotatably connected. The first hinge 131 is disposed on the first body 11, and the second hinge 132 is disposed on the second body 12, with the first body 11 and the second body 12 hinged together by the first hinge 131 and the second hinge 132. The first hinge 131 may be disposed on the base 200, and the second hinge 132 may be disposed on the housing 300. The connection method between the first hinge 131 and the first body 11, and the connection method between the second hinge 132 and the second body 12, are not limited, and may include, but are not limited to, screw connection, welding, or bonding.

[0052] Optionally, the heat-drying device 10 includes a limiting hinge 13. The limiting hinge 13 may include a first hinge member 131 and a second hinge member 132. The first body 11 and the second body 12 are hinged together by the limiting hinge 13. The limiting hinge 13 is used to maintain the first body 11 and the second body 12 at the preset angle when the second body 12 rotates relative to the first body 11 to the preset angle.

[0053] Specifically, the limiting hinge 13 can achieve a limiting effect at a preset angle through the limiting cooperation between the first hinge member 131 and the second hinge member 132 along the relative rotation direction of the first body 11 and the second body 12, so that the first body 11 and the second body 12 can be maintained at the preset angle.

[0054] In other embodiments, the limiting hinge 13 can also achieve the above-mentioned effect through its limiting cooperation with the first body 11 or the second body 12. The limiting hinge 13 may include only one hinge member or include two or more hinge members, and the specifics are not limited. The following description mainly takes the example of the limiting hinge 13 including a first hinge member 131 and a second hinge member 132, and the provision of limiting structures on the first hinge member 131 and the second hinge member 132.

[0055] The limiting hinge 13 may further include a pivot 133, which passes through the first hinge member 131 and the second hinge member 132, allowing the first hinge member 131 to rotate relative to the second hinge member 132 about the pivot 133. In other embodiments, the limiting hinge 13 may not include a pivot 133, and one of the first hinge member 131 and the second hinge member 132 may have a protruding post inserted into the other.

[0056] The first hinge member 131 is provided with a first limiting part 134, and the second hinge member 132 is provided with a second limiting part 135. Along the rotation direction of the first hinge member 131 and the second hinge member 132, the first limiting part 134 and the second limiting part 135 form a limiting engagement.

[0057] Understandably, the rotation direction of the first hinge 131 and the second hinge 132 is the same as the rotation direction of the first body 11 and the second body 12. In other words, the second body 12 can rotate relative to the first body 11 along this rotation direction. The first limiting part 134 and the second limiting part 135 form a limiting engagement along this rotation direction, indicating that the first limiting part 134 and the second limiting part 135 can limit the movement stroke of the first hinge 131 and the second hinge 132 in this rotation direction. For example, under the limiting action of the limiting hinge 13, the maximum included angle formed by the first body 11 and the second body 12 when rotating relative to each other can be 100-110 degrees, so as to facilitate the user's closing operation.

[0058] Specifically, the first limiting part 134 can be an arc-shaped groove that extends along the rotation direction. The second limiting part 135 can be a protrusion that is located in the arc-shaped groove.

[0059] When the first hinge 131 rotates clockwise relative to the second hinge 132 to the first angle threshold, the first limiting part 134 abuts against one end of the second limiting part 135, that is, the protrusion abuts against one end of the arc-shaped groove wall, so that the first limiting part 134 and the second limiting part 135 can cooperate to prevent the first hinge 131 from rotating clockwise relative to the second hinge 132 further.

[0060] When the first hinge 131 is reversed relative to the second hinge 132 to the second angle threshold, the first limiting part 134 abuts against the other end of the second limiting part 135, that is, the protrusion abuts against the other end of the arc-shaped groove wall, so that the first limiting part 134 and the second limiting part 135 can cooperate to prevent the first hinge 131 from being further reversed relative to the second hinge 132.

[0061] In this embodiment, the first limiting part 134 can be disposed on the end face of the first hinge member 131 facing the second hinge member 132, and the second limiting part 135 can be disposed on the end face of the second hinge member 132 facing the first hinge member 131. In other embodiments, the first limiting part 134 and the second limiting part 135 can also be arranged in other ways. For example, the first hinge member 131 and the second hinge member 132 are also provided with corresponding protrusions, and the first limiting part 134 and the second limiting part 135 can be disposed on the protrusions. The first limiting part 134 and the second limiting part 135 can also be designed as other structures that can achieve upper limit cooperation in the rotation direction. For example, the first limiting part 134 and the second limiting part 135 are both protrusions, one of which can prevent the first hinge member 131 from rotating further relative to the second hinge member 132 when it abuts against the opposite sides of the other.

[0062] In other embodiments, similar limiting structures may also be provided on at least one of the first body 11 and the second body 12, as well as on the limiting hinge 13, to achieve a similar limiting effect.

[0063] It should be understood that the terminology used in this specification and appended claims is for the purpose of describing particular embodiments only and is not intended to limit the application. As used in this specification and appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise. Similarly, the terms “first” and “second” in the description of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include one or more of the stated features. Furthermore, the term “multiple” in the description of this application means two or more, unless otherwise explicitly specified.

[0064] Please see Figures 9 to 11 , Figure 9 This is a three-dimensional structural diagram of the second body provided in some embodiments of this application. Figure 10 yes Figure 9 A three-dimensional structural diagram of the second body in the embodiment from another perspective. Figure 11 yes Figure 9 A cross-sectional structural diagram of the second body in the embodiment.

[0065] In some embodiments, the second body 12 includes an air duct 102 disposed in the housing 300, through which the heating chamber 101 communicates with the external environment. An air inlet 301 and an air outlet 302 are provided. The air inlet 301 communicates with the heating chamber 101, allowing gas from the heating chamber 101 to enter through the air inlet 301. The air outlet 302 communicates with the air inlet 301, allowing gas from the heating chamber 101 to enter the inner cavity of the housing 300 through the air inlet 301 and then exit through the air outlet 302. The air inlet 301 is located on the bottom surface of a portion of the cavity wall of the housing 300 that forms part of the heating chamber 101.

[0066] In this embodiment, the heat drying device 10 can be used to heat dry the heat transfer film in the heat drying chamber 101. During the heat drying process, the ink layer on the heat transfer film gradually solidifies to form a transferable layer, and the glycerol in the ink evaporates into the heat drying chamber 101. In this embodiment, by opening an air inlet 301 and an air outlet 302 connected to the heat drying chamber 101 in the housing 300, the glycerol vapor in the heat drying chamber 101 can leave the heat drying chamber 101 through the air inlet 301 and then be discharged through the air outlet 302. On the one hand, this prevents the glycerol vapor from gradually condensing into liquid oil droplets on the cavity wall of the heat drying chamber 101, thereby preventing the heat transfer film from being contaminated by oil droplets. On the other hand, by discharging the glycerol vapor in the heat drying chamber 101, it prevents the glycerol in the ink layer of the heat transfer film from becoming saturated with glycerol vapor in the heat drying chamber 101 and difficult to evaporate during the heat drying process, thus preventing the heat transfer film from experiencing oil return.

[0067] It should be noted that preventing a certain phenomenon mentioned in this article does not mean completely eliminating it, but rather reducing the likelihood of it occurring.

[0068] Optionally, an air inlet 121 is provided on the bottom surface of the housing 300, and an air inlet 301 is opened on the side wall of the air inlet 121. The bottom surface of the housing 300 is used to form the top cavity wall of the hot drying chamber 101. During the hot drying process, glycerol vapor that evaporates into the hot drying chamber 101 will rise to the top of the hot drying chamber 101. In this embodiment, by providing an air inlet 121 on the top cavity wall of the hot drying chamber 101 and opening the air inlet 301 on the side wall of the air inlet 121, the glycerol vapor that evaporates to the top of the hot drying chamber 101 can be discharged from the hot drying chamber 101 through the air inlet 301, so as to prevent the glycerol vapor from condensing into droplets on the top cavity wall of the hot drying chamber 101.

[0069] The air inlet 301 can be an elongated through-hole. Multiple air inlets 301 can be provided on the air intake section 121 to allow glycerol vapor from various locations at the top of the heating chamber 101 to be discharged through each air inlet 301. In other embodiments, the arrangement of the air inlets 301 is not limited to this embodiment. For example, the air inlet 301 can be directly formed on the bottom surface of the housing 300; or, the air inlet 301 can be a circular or square hole.

[0070] In some embodiments, the hot drying apparatus 10 may further include a condensing assembly 400 disposed on the housing 300, the condensing assembly 400 having a condensing chamber 401. The condensing chamber 401, the hot drying chamber 101, and the external environment are connected through the air passage 102. The condensing assembly 400 is used to condense a portion of the airflow into liquid and to collect the liquid.

[0071] The housing 300 may be provided with a first air passage 303 and a second air passage 304. One end of the first air passage 303 forms an air inlet 301, and one end of the second air passage 304 forms an air outlet 302. The other ends of the first air passage 303 and the second air passage 304 are respectively connected to the condenser chamber 401.

[0072] In other words, the first air passage 303, the condensing chamber 401, and the second air passage 304 are connected in sequence. The end of the first air passage 303 away from the condensing chamber 401 forms the air inlet 301, and the end of the second air passage 304 away from the condensing chamber 401 forms the air outlet 302. Thus, the gas in the heating chamber 101 can enter the first air passage 303 through the air inlet 301, and then pass through the first air passage 303, the condensing chamber 401, and the second air passage 304 in sequence before being discharged through the air outlet 302. During the gas discharge process, the glycerol vapor in the gas will condense into liquid when passing through the condensing chamber 401 and be collected in the condensing chamber 401, thereby preventing the glycerol vapor from being discharged from the air outlet 302 and causing pollution.

[0073] In other embodiments, the air duct 102 of the heating device 10 can also be designed with other structures, not limited to the design of the first air duct 303 and the second air duct 304 described above, as long as the air duct 102 can connect the heating chamber 101, the condensing chamber 401 and the external environment. The following description mainly takes the design of the air duct 102 as the first air duct 303 and the second air duct 304 as an example.

[0074] In some embodiments, the second body 12 further includes a fan 122 disposed in the housing 300, used to push gas within the air passage 102 to form an airflow. The fan 122 generates an airflow from the air inlet 301 to the air outlet 302, thereby drawing glycerol vapor from the heating chamber 101 into the first air passage 303, where it condenses into liquid in the condensing chamber 401. The air in the heating chamber 101 is then further drawn into the second air passage 304 after passing through the condensing chamber 401, and subsequently discharged through the air outlet 302. The air outlet 302 can be connected to the outside, allowing the airflow through it to be discharged to the outside. In other embodiments, the air outlet 302 can also be connected to another cavity of the heating device 10, allowing the airflow through it to be discharged into that cavity.

[0075] The fan 122 can be disposed in the second air duct 304, specifically in the area of ​​the housing 300 near the air outlet 302. The fan 122 is, for example, but not limited to, a fan or blower. In other embodiments, the fan 122 can also be disposed in other locations capable of generating the aforementioned airflow. Furthermore, the cavity wall of the heating chamber 101 can have a through-hole communicating with the outside, allowing outside air to enter the heating chamber 101 to facilitate the formation of the aforementioned airflow; alternatively, a gap can be formed between the first body 11 and the second body 12, allowing outside air to enter the heating chamber 101 through this gap.

[0076] A condenser assembly 400 may be disposed at the edge of the housing 300 along the first width direction X of the heating device 10, for condensing the chemical reagent vapor in the airflow into a liquid and for collecting the liquid. The chemical reagent vapor may be, for example, but is not limited to, glycerol vapor.

[0077] Wherein, the first width direction X is perpendicular to the height direction Z of the heating device 10. The height direction Z of the heating device 10 is the height direction Z of the heating device 10 under normal operating conditions. Taking the heating device 10 placed vertically as an example, its height direction Z is vertical, and its first width direction X is horizontal. The first body 11 and the second body 12 can be arranged along the height direction Z of the heating device 10, wherein the first body 11 can be regarded as the lower body of the heating device 10, and the second body 12 can be regarded as the upper body of the heating device 10.

[0078] In this embodiment, by placing the condensing component 400 at the edge of the housing 300 along the first width direction X, the temperature influence from the heating component 100 on the condensing component 400 can be reduced, which is beneficial to improving the condensing efficiency.

[0079] In some embodiments, the condensation assembly 400 includes a condensation container 410, which surrounds and forms a condensation chamber 401. The condensation container 410 may be disposed at the edge of the housing 300 along the first width direction X.

[0080] Optionally, the outer surface of the condenser container 410 constitutes part of the outer surface of the heating device 10, allowing it to contact the outside air. In other words, the outer wall of the condenser cavity 401 can be exposed to the outside, thereby improving the cooling effect of the environment on the condenser cavity 401. Understandably, since the heating device 10 needs to perform heating during operation, its internal temperature is usually higher than the ambient temperature. Through the above design, this embodiment can utilize the environment to cool the condenser cavity 401, making the overall temperature of the condenser cavity 401 relatively lower than the temperature of glycerol vapor, thereby improving condensation efficiency. In other embodiments, the condenser container 410 may also be hidden inside the housing 300 and not constitute part of the outer surface of the heating device 10.

[0081] Optionally, the projections of the condensing component 400 and the heating component 100 onto the housing 300 do not overlap or only partially overlap. The projection directions of both the condensing component 400 and the heating component 100 onto the housing 300 can be the height direction Z. For example... Figure 3 As shown, along the first width direction X, the condensing container 410 can be arranged at intervals with the heating component 100 so that the projections of the condensing component 400 and the heating component 100 on the housing 300 do not overlap. In other words, the heating device 10 can stagger the condensing area and the heating area to reduce the heat radiation effect of the heating component 100 on the condensing cavity 401. In other embodiments, the condensing container 410 and the heating component 100 may also have a partially overlapping area, so that the projections of the condensing component 400 and the heating component 100 on the housing 300 partially overlap. In this case, by placing the condensing container 410 at the edge of the housing 300, it is still possible to reduce some of the influence of the heating component 100 on the condensing cavity 401.

[0082] Please see Figure 11 and Figure 12 , Figure 12 yes Figure 11 The diagram shows a cross-sectional view of the hot drying device from another perspective.

[0083] In some embodiments, the housing 300 may include a first housing 310 and a second housing 320, the first housing 310 forming a first air passage 303 and the second housing 320 forming a second air passage 304. The connection method and specific structure of the first housing 310 and the second housing 320 are not limited.

[0084] Specifically, the first housing 310 and the second housing 320 can be wholly or partially integral structures, or they can be completely separate structures. The first housing 310 itself can be an integral or separate structure, and the second housing 320 itself can also be an integral or separate structure. For example, the housing 300 may include multiple components, which cooperate to form the first housing 310 and the second housing 320. Alternatively, the housing 300 may include two components, which respectively serve as the first housing 310 and the second housing 320. Furthermore, the housing 300 may include a single component forming the first housing 310 and the second housing 320.

[0085] Optionally, the first housing 310 and the second housing 320 are arranged along the height direction Z of the heating device 10. The condenser container 410 can be connected to one end of the first housing 310 along the first width direction X of the heating device 10, and to one end of the second housing 320 along the first width direction X, so that the first air passage 303, the condensation chamber 401 and the second air passage 304 cooperate to form an airflow channel that bends at the condensation chamber 401.

[0086] In this embodiment, the first housing 310 and the second housing 320 are arranged along the height direction Z of the heating device 10, and the condenser container 410 is connected along the first width direction X to one end of the first housing 310 and one end of the second housing 320. This allows the airflow from the inlet 301 to the outlet 302 to turn in the condenser chamber 401 after exiting the first air passage 303 before flowing into the second air passage 304. This increases the contact area between the inner wall of the condenser container 410 and the airflow, which is beneficial to improving the condensation efficiency.

[0087] The specific shapes of the first air passage 303, the second air passage 304, and the condensation chamber 401 are not limited; the above design only indicates the approximate orientation of the first air passage 303, the second air passage 304, and the condensation chamber 401. In other embodiments, the relative positions of the first housing 310, the second housing 320, and the condensation container 410 are not limited to the above design. For example, the first housing 310, the condensation container 410, and the second housing 320 may be arranged in the same direction.

[0088] Please see Figures 11 to 13 , Figure 13 yes Figure 12 A partial cross-sectional schematic diagram of the hot drying device is shown.

[0089] In some embodiments, the condensation assembly 400 may include a condensation container 410 and an air passage 420. The air passage 420 has a plurality of air passage holes 402, which are through holes. The first air passage 303 is connected to the condensation chamber 401 through the air passage holes 402, so that the airflow in the first air passage 303 will enter the condensation chamber 401 through the air passage holes 402.

[0090] The air passage 420 can be, but is not limited to, a plate. The air passage 420 can be disposed on the housing 300 or the condenser container 410. The air passage 402 is a small hole formed on the air passage 420. In this embodiment, by connecting the first air passage 303 to the condenser chamber 401 through the air passage 402, the glycerol vapor in the airflow can pass through the air passage 402 and enter the relatively spacious condenser chamber 401 during its flow, thereby reducing the air pressure and improving condensation efficiency.

[0091] Optionally, the vent 402 is a circular hole with a diameter of 1-5 mm, such as 2 mm, 3 mm, 4 mm, etc. This diameter refers to the diameter of the vent 402. In other embodiments, the vent 402 can also be a through hole of other shapes, such as a square hole, and the maximum cross-sectional length of the vent 402 can be 1-5 mm.

[0092] In this embodiment, by designing the aperture of the vent 402 to be 1-5mm, the airflow can flow rapidly while effectively reducing air pressure, thereby efficiently condensing chemical reagent vapors in the condensation chamber 401. In other embodiments, the vent 402 can be designed with other apertures as needed. Multiple vents 402 can be arranged in an array to improve airflow efficiency. In other embodiments, the multiple vents 402 can also be arranged in other ways.

[0093] In some embodiments, a guide portion 311 may be provided at one end of the housing 300 near the condenser container 410. The guide portion 311 may be part of the first housing 310 or another component connected to the first housing 310. The guide portion 311 is used to guide the flow direction of airflow, and may be, for example, but not limited to, an arc-shaped plate.

[0094] Optionally, the guide portion 311 is used to guide the airflow to the area of ​​the air passage 420 where the air passage hole 402 is provided, so as to improve the efficiency of the airflow entering the condensing chamber 401 through the air passage hole 402. The air passage 420 may be connected to the housing 300 and cover part of the condensing chamber 401. For example, the air passage 420 may be... Figure 13 The plate shown can cover the portion of the condensing cavity 401 near the first air passage 303 along the first width direction X. The extension direction of the guide portion 311 can form an acute angle with the first width direction X, so that the guide portion 311 can guide the airflow to flow in the direction of the air passage 420, so as to prevent the airflow from bypassing the air passage 420 and flowing directly into the condensing cavity 401.

[0095] In this manner, after the airflow enters the condensing chamber 401 through the air passage 402, it bypasses the air passage 420 and flows into the second air passage 304 through the portion of the condensing chamber 401 not covered by the air passage 420. This increases the contact area between the condensing container 410 and the airflow, thereby improving condensation efficiency. In other embodiments, the air passage 420 may completely cover one end of the first air passage 303 or completely cover the condensing chamber 401, so that the airflow in the first air passage 303 must pass through the air passage 402 to enter the condensing chamber 401. Of course, the condensing assembly 400 may also not include the air passage 420; the above are merely examples provided by embodiments of this application.

[0096] Optionally, as described above, the first housing 310 and the second housing 320 are arranged along the height direction Z of the heating device 10, and the condenser container 410 is connected to one end of the first housing 310 along the first width direction X, and is also connected to one end of the second housing 320 along the first width direction X, so that the first air passage 303, the condenser cavity 401 and the second air passage 304 cooperate to form an airflow channel that bends at the condenser cavity 401.

[0097] The condenser container 410 includes a condenser wall 411 surrounding and forming a condensation chamber 401. Along the height direction Z of the heating device 10, a portion of the condenser wall 411 may be located on the bottom side of the first housing 310 and connected to the first housing 310. Another portion of the condenser wall 411 may be located on the top side of the first housing 310 and connected to the second housing 320. In other words, as... Figure 13 As shown, the condensing chamber 401 is located on the same side of the first air passage 303 and the second air passage 304 along the first width direction X, and part of it is located below the first air passage 303 along the height direction Z, while part of it is located above the first air passage 303 along the height direction Z. The condensing container 410 may protrude from the bottom of the first housing 310 along the height direction Z.

[0098] Through the above design, the condensing chamber 401 can be formed with a space for the airflow to flow downward after exiting the first air passage 303, and a space for the airflow to flow further upward to the second air passage 304. A guide portion 311 can be provided at one end of the first housing 310 near the condensing container 410. The guide portion 311 is used to guide the airflow to the portion of the condensing wall 411 located on the bottom side of the first housing 310, so that the airflow forms a vortex in the condensing chamber 401. Understandably, unless otherwise specified, when referring to the height direction Z, this document uniformly refers to the height direction Z of the heat drying device 10.

[0099] In some embodiments, such as Figure 13 As shown, the condensation chamber 401 can be a groove formed by the condensation wall 411. The condensation wall 411 can include a first side wall, a second side wall, a bottom wall and a top wall. The first side wall and the second side wall are opposite to each other and spaced apart. The bottom wall is connected between the bottom end of the first side wall and the bottom end of the second side wall. The top wall is connected between the top end of the second side wall and the second housing 320.

[0100] The first sidewall can be connected to one end of the first housing 310 and is bent relative to the first housing 310, so that the first sidewall protrudes towards the bottom side of the first housing 310 along the height direction Z, thereby giving the condensing cavity 401 a portion located at the bottom side of the first air passage 303. The guide portion 311 can form an acute angle with both the first sidewall and the bottom wall of the condensing wall 411, and is used to guide the airflow towards the direction of the bottom wall of the condensing wall 411, so that at least part of the airflow will flow into the second air passage 304 after flowing through the bottom wall, the second sidewall and the top wall of the condensing wall 411. As a result, the glycerol vapor will form a vortex-shaped airflow path in the condensing cavity 401, which is beneficial to increasing the contact area between the glycerol vapor and the condensing wall 411, thereby improving the condensation efficiency.

[0101] In other embodiments, the condensation cavity 401 may also be an arc-shaped groove formed by a condensation wall 411. The condensation wall 411 may be an arc-shaped wall, with a portion protruding from the bottom end of the first housing 310 along the height direction Z, and a portion located on the top side of the first housing 310 along the height direction Z. Similarly, the guide portion 311 may form an acute angle with a section of the condensation wall 411 near the first housing 310 to guide the airflow to form a vortex in the condensation cavity 401. In other embodiments, the condensation cavity 401 may also be designed in other shapes, not limited to a groove, and the condensation cavity 401 may also be located entirely below or above the first air passage 303 along the height direction Z.

[0102] Optionally, by combining the above-mentioned designs, the airflow in the first air passage 303 can flow into the condensing chamber 401 through the air passage 402, thereby forming a vortex in the condensing chamber 401. Based on the effects of reduced air pressure and increased condensing contact area, the condensing efficiency can be significantly improved.

[0103] Please see Figure 13 and Figure 14 , Figure 14 This is a three-dimensional structural schematic diagram of a condensation assembly provided in some embodiments of this application.

[0104] In some embodiments, the condenser container 410 can be detachably connected to the housing 300, and the specific connection method is, for example, but not limited to, snap-fit ​​or pin-fit. The condenser container 410 can be configured to move relative to the housing 300 along a first width direction X to achieve connection or separation from the housing 300.

[0105] Optionally, the condensation assembly 400 includes a condensation container 410 and a connecting shaft 430, with the connecting shaft 430 disposed on the condensation container 410. The connecting shaft 430 can extend along a second width direction Y of the heating device 10. The second width direction Y is another width direction of the heating device 10, and is perpendicular to the first width direction X and the height direction Z. The condensation container 410 can move relative to the housing 300 along the first width direction X to be engaged with or detached from the housing 300 via the connecting shaft 430.

[0106] A connecting clip 321 may be provided at one end of the housing 300 along the first width direction X. The connecting shaft 430 can be engaged with the connecting clip 321 to achieve a detachable connection between the condenser container 410 and the housing 300. The condenser container 410 is configured to move relative to the housing 300 along the first width direction X, so that the connecting shaft 430 can be connected to or separated from the connecting clip 321. The connecting clip 321 may be, for example, a U-shaped clip with its opening facing the connecting shaft 430. There may be one or more connecting clips 321, and multiple connecting clips 321 may be spaced apart along the second width direction Y.

[0107] The connecting shaft 430 can pass through the condenser container 410 to achieve relative fixation between them. During assembly, the condenser container 410 can slide towards the housing 300 along the first width direction X. When it slides into place, the connecting shaft 430 will engage with the connecting buckle 321. The connecting buckle 321, based on its own elastic deformation, will lock the connecting shaft 430, thereby preventing the condenser container 410 from accidentally detaching from the housing 300. When the user needs to disassemble and clean the condenser container 410, they only need to pull the condenser container 410 away from the housing 300 along the first width direction X, which will allow the connecting shaft 430 to slide out over the pre-tightening force of the connecting buckle 321, thus achieving quick disassembly of the condenser container 410.

[0108] In other embodiments, the surface of the condenser container 410 may be provided with protruding posts or other structures that can achieve a snap-fit ​​function, so that the condenser container 410 can snap itself onto the housing 300 without the need for a connecting shaft 430.

[0109] Please see Figure 14 and Figure 15 , Figure 15 yes Figure 14 A three-dimensional structural diagram of the condenser container in the embodiment.

[0110] In some embodiments, the condenser container 410 is a transparent container, allowing the user to observe the water level inside from its outer surface. The outer surface of the condenser container 410 may be provided with graduation lines 412, which serve as reference water level indicators. For example, graduation lines 412 may serve as a maximum water level indicator. Alternatively, graduation lines 412 may serve as an 80% water level indicator.

[0111] The heating device 10 can have multiple operating states, and the second body 12 is positioned differently relative to the first body 11 in different operating states. The heating device 10 can switch from one operating state to another by moving the second body 12 relative to the first body 11. The outer surface of the condenser container 410 can be provided with multiple scale lines 412, and the multiple scale lines 412 correspond one-to-one with multiple operating states. Different scale lines 412 are used as reference water level marks of the condenser container 410 in different operating states, so that the user can observe the internal water level of the condenser container 410 in each operating state, and can accurately determine the water level height inside the condenser container 410 by comparing the water level with the scale lines 412.

[0112] The heating device 10 may have a first working state and a second working state. The second body 12 may move relative to the first body 11 so that the heating device 10 switches between the first working state and the second working state, thereby the second body 12 and the first body 11 have different relative orientations in the first working state and the second working state.

[0113] The outer surface of the condenser 410 may be provided with a first scale line 4121 and a second scale line 4122. The first scale line 4121 corresponds to a first working state, and the second scale line 4122 corresponds to a second working state. The first scale line 4121 can serve as a reference water level mark for the condenser 410 in the first working state, and the second scale line 4122 can serve as a reference water level mark for the condenser 410 in the second working state.

[0114] The first graduation line 4121 and the second graduation line 4122 are positioned differently on the outer surface of the condenser container 410. For example, the first graduation line 4121 can be located on the side of the condenser container 410, and the second graduation line 4122 can be located on the bottom surface of the condenser container 410. Of course, the first graduation line 4121 and the second graduation line 4122 can also be located in other different positions, depending on the actual situation.

[0115] Taking the hinged connection between the first body 11 and the second body 12 as an example, the heating device 10 can switch between a first working state and a second working state by rotating the second body 12 relative to the first body 11. In the first working state, the second body 12 covers the first body 11 and together with the first body 11 forms a heating cavity 101. In the second working state, the second body 12 is partially separated from the first body 11 and forms an angle greater than 0 with the first body 11.

[0116] In different operating states, due to the different relative orientations of the second body 12 and the first body 11, the position of the condenser container 410 exposed to the user's field of vision may also differ. For example, in the first operating state, the side of the condenser container 410 is exposed to the user's field of vision, and the first scale line 4121 can be set on the side of the condenser container 410, so that the user can know the internal water level information of the condenser container 410 in the first operating state according to the first scale line 4121; in the second operating state, the bottom surface of the condenser container 410 is exposed to the user's field of vision, and the second scale line 4122 can be set on the bottom surface of the condenser container 410, so that the user can know the internal water level information of the condenser container 410 in the second operating state according to the second scale line 4122.

[0117] Please refer to the above text. Figure 16 , Figure 16 This is an exploded structural diagram of the second organism provided in some embodiments of this application.

[0118] In some embodiments, the housing 300 may include a lower housing 330, a middle housing 340, and an upper housing 350, which can be combined to form a first housing 310 and a second housing 320.

[0119] The lower shell 330 may include a cover plate 331 and a frame 332. The cover plate 331 can cover the first body 11 and forms part of the cavity wall of the hot drying cavity 101. The frame 332 surrounds the cover plate 331. The cover plate 331 can be made of transparent or partially transparent material, so that the user can observe the drying status of the heat transfer film in the hot drying cavity 101 through the cover plate 331, which facilitates manual confirmation of the film's drying status. A handle 123 may be provided on the outer surface of the frame 332 to facilitate the user to grip and lift the lower shell 330.

[0120] The middle shell 340 can be disposed on the lower shell 330 and together with the lower shell 330 to form the first shell 310. The lower shell 330 may have an assembly hole 305, through which the middle shell 340 passes to form... Figure 10 The air intake 121 is shown. The condenser 410 can be connected to the middle shell 340, specifically to one end of the middle shell 340 along the first width direction X. The upper shell 350 can cover the middle shell 340 and cooperate with the middle shell 340 to form the second shell 320. In other words, the middle shell 340 has a portion for forming the first shell 310 with the lower shell 330, and another portion for forming the second shell 320 with the upper shell 350. In other embodiments, the first shell 310 and the second shell 320 can also be designed with other structures. Figure 16 The housing 300 shown is merely an example provided by the embodiments of this application.

[0121] It should be understood that the terms "comprising" and "having," and any variations thereof, used in this application and the appended claims, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0122] Please refer to the above text. Figure 12 and Figure 17 , Figure 17 This is an exploded structural diagram of the second organism provided in some embodiments of this application.

[0123] In some embodiments, the second body 12 may include a filter element 500. The filter element 500 may be disposed in the air passage 102, for example, in the second air passage 304, for adsorbing impurities in the airflow.

[0124] Understandably, during the heat drying process of the material in the heat drying device 10, the gases volatilized from the material may contain not only chemical reagent vapors that can be condensed into liquid, but also other chemical reagent components that are difficult to condense into liquid. If these chemical reagent components are discharged directly without treatment, they may be absorbed by the user, causing physical discomfort, or they may pollute the environment. In this embodiment, by setting a filter element 500 in the second air duct 304, the airflow passes through the filter element 500 after passing through the condensation chamber 401 and before being discharged through the air outlet 302, thereby reducing harmful substances in the airflow discharged from the air outlet 302.

[0125] In other embodiments, the filter element 500 may also be disposed in the first air passage 303. In this embodiment, by disposing of the filter element 500 in the second air passage 304, the airflow passes through the condenser chamber 401 before passing through the filter element 500. This allows chemical reagent vapors that can be condensed into liquid, such as glycerol vapor, to be condensed and stored in the condenser chamber 401. This reduces the amount of material that the filter element 500 needs to adsorb, thus extending the service life of the filter element 500.

[0126] Optionally, the housing 300 also includes a mounting base 360, which is movably connected to another part of the housing 300, i.e., the other part of the housing 300 excluding the mounting base 360. Specifically, the mounting base 360 ​​can be part of the upper housing 350 and movably connected to another part of the upper housing 350. The filter element 500 is detachably disposed in the mounting base 360, so that the user can control the movement of the mounting base 360 ​​to expose the filter element 500 for easy replacement. The movable connection between the mounting base 360 ​​and the housing 300 can be hinged.

[0127] Please see Figure 12 and Figure 17 and Figure 18 , Figure 18 yes Figure 17 A further exploded structural diagram of the second body in the embodiment.

[0128] In some embodiments, both the fan 122 and the filter element 500 can be mounted on the mounting base 360. The filter element 500 and the fan 122 can be arranged overlappingly along the airflow direction in the air passage 102, for example, along the airflow direction in the second air passage 304. This allows the suction force provided by the fan 122 to help the airflow pass smoothly through the filter element 500 when it flows near it, thereby improving airflow efficiency. The mounting base 360 ​​can have an air inlet 301, allowing the fan 122 mounted on the mounting base 360 ​​to blow airflow out of the air inlet 301, ensuring smooth airflow discharge.

[0129] The mounting base 360 ​​may include a base 361 and a flip cover 362. The base 361 is primarily used to mount the fan 122 and the filter element 500, which can be respectively positioned on opposite sides of the base 361 along the height direction Z. The base 361 may have through holes to allow airflow through the filter element 500 to the fan 122. The flip cover 362 is primarily used for user-controlled movement to facilitate user removal of the filter element 500. The flip cover 362 covers the fan 122 and the mounting base 360, and an air outlet 302 may be provided on the flip cover 362. The base 361 and the flip cover 362 are fixedly connected, and the flip cover 362 can be hinged to other parts of the housing 300. The flip cover 362 has a pressing tab 363, which is detachably snapped onto other parts of the housing 300.

[0130] When the user needs to replace the filter element 500, they can manually move the pressing plate 363 to release the locking relationship between the pressing plate 363 and other parts of the housing 300. Then, the user can lift the flip cover 362 to lift the mounting base 360, exposing the filter element 500. The filter element 500 may be equipped with a pull strap (not shown) to facilitate removal of the filter element 500 from the mounting base 360 ​​by pulling the strap. After replacing the filter element 500, the user simply needs to rotate and press the mounting base 360 ​​together.

[0131] Please see Figure 12 , Figure 19 and Figure 20 , Figure 19 This is a schematic diagram of the structure of the filter element provided in some embodiments of this application. Figure 20 This is a schematic diagram of the filter element provided in other embodiments of this application. This embodiment uses... Figure 19 and Figure 20 The upward direction is used as the flow direction of airflow in the second airway 304.

[0132] In some embodiments, the filter element 500 may include a liquid-absorbing layer 510 and a deodorizing layer 520, with at least a portion of the liquid-absorbing layer 510 and the deodorizing layer 520 stacked together along the flow direction of the airflow in the air passage 102, for example, along the flow direction of the airflow in the second air passage 304. The liquid-absorbing layer 510 is primarily used to absorb liquid, and its material is, for example, but not limited to, electrostatic cotton and / or polytetrafluoroethylene (PTFE) with oleophobic and hydrophobic properties. The deodorizing layer 520 is primarily used to achieve deodorization and purification, and its material is, for example, but not limited to, activated carbon.

[0133] In this embodiment, by arranging the liquid-absorbing layer 510 and the deodorizing layer 520 in the manner described above, the airflow will first pass through the liquid-absorbing layer 510 and then through the deodorizing layer 520, thereby preventing residual oil and moisture in the airflow from entering the deodorizing layer 520 and causing blockage or material deterioration of the deodorizing layer 520.

[0134] Among them, the liquid absorption layer 510 can be as follows: Figure 19 As shown, the entire structure is stacked with the deodorizing layer 520. The liquid-absorbing layer 510 can also be arranged as follows: Figure 20 As shown, a portion of the deodorizing layer 520 is stacked on top of the deodorizing layer 520; wherein, other portions of the liquid-absorbing layer 510 may cover the deodorizing layer 520 to prevent leakage of the deodorizing layer 520.

[0135] Optionally, the filter element 500 further includes another liquid-absorbing layer 510. The deodorizing layer 520 and the other liquid-absorbing layer 510 can be stacked along the flow direction of the airflow in the second air passage 304, so that the other liquid-absorbing layer 510 can cooperate with the liquid-absorbing layer 510 located on the other side of the deodorizing layer 520 to wrap around the deodorizing layer 520 to prevent the deodorizing layer 520 from leaking. The two liquid-absorbing layers 510 can be an integral structure or a separate structure.

[0143] Please refer to the following: Figure 1 , Figure 16 and Figure 21 In some embodiments, the hot drying device 10 may include an interactive component 600 and a handle 123, both of which are disposed on the housing 300. The housing 300 includes an upper shell 350 and a lower shell 330, the lower shell 330 and the base 200 are fitted together to form a hot drying cavity 101, and the upper shell 350 protrudes from the side of the lower shell 330 away from the base 200.

[0144] In some embodiments, the interaction component 600 may be disposed on the upper shell 350, and the handle 123 may be disposed on the lower shell 330. The handle 123 may be as follows: Figure 21The handle 123 is provided on the outer surface of the lower housing 330 as shown. Taking the hinged connection between the first body 11 and the second body 12 as an example, the handle 123 can be provided on the outer surface of the lower housing 330 at the end away from the hinge position of the two bodies, so as to facilitate the user to control the opening and closing of the second body 12.

[0145] In other embodiments, the interaction component 600 and the handle 123 can both be disposed on the upper shell 350. At least one end of the upper shell 350 can extend along a first width direction X to the outer surface of the lower shell 330, and the handle 123 can be disposed on the outer surface of the upper shell 350 along the first width direction X. Taking the hinged connection between the first body 11 and the second body 12 as an example, the end of the upper shell 350 away from the hinge position of the two bodies can extend to the outer surface of the lower shell 330, forming part of the outer surface of the housing 300, and the handle 123 can be disposed on the outer surface of the upper shell 350 away from the hinge position of the two bodies. Of course, the end of the upper shell 350 away from the hinge position of the two bodies can also be disposed as follows... Figure 21 The area shown is located within the inner perimeter of the lower shell 330.

[0146] The housing 300 may include a lower housing 330, a middle housing 340, and an upper housing 350, the specific structure of which has been described above and will not be repeated here. In other embodiments, the housing 300 may also be composed of a lower housing 330 and an upper housing 350. For example, in this embodiment, the upper housing 350 can be replaced with... Figure 16 The combined structure of the middle shell 340 and the upper shell 350 shown is consistent with... Figure 16 The lower shell 330 shown constitutes the housing 300.

[0147] In this embodiment, the hot drying device 10 can continuously operate the fan 122 during the hot drying process of the material. When the fan 122 is operating, it will drive the airflow, so that the chemical reagent vapor in the hot drying chamber 101 will continuously enter the first air channel 303, and then flow to the condensing chamber 401 to condense into liquid and be collected by the condensing chamber 401. The airflow passing through the condensing chamber 401 will further enter the second air channel 304, and be discharged after passing through the filter element 500. At this time, the discharged airflow has undergone condensation purification and filtration purification, realizing oil removal and deodorization, which greatly improves the environmental protection of the hot drying device 10. Since the chemical reagent vapor in the hot drying chamber 101 is continuously drawn away, the chemical reagent vapor does not have time to condense into liquid on the cavity wall of the hot drying chamber 101, thereby solving the problem of easy accumulation of liquid droplets on the cavity wall of the hot drying chamber 101, which is beneficial to improving the user experience.
