Description

Technical Field

[0001] The present invention relates to the technical field of axial flow fans, and more specifically, to an axial flow air duct assembly and an axial flow hair dryer. Background Art

[0002] As the core component of the ventilation system, the axial flow duct assembly performs well in gas delivery and heat dissipation, but it is difficult for existing technologies to coordinately deal with humidity and VOCs pollution. The traditional structure relies on the basic combination of axial flow fans, air guide covers and shells, which exposes obvious defects in high temperature and high humidity or corrosive gas environments: humid air can easily cause motor corrosion and microbial growth, and direct VOCs emissions aggravate environmental pollution. Although the current external purification module can solve the problem independently, it increases energy consumption and airflow noise due to increased wind resistance, and it is difficult to balance purification efficiency and aerodynamic performance.

[0003] The lack of environmental adaptability of axial flow fans has become a key bottleneck. Water vapor condensation in high humidity environments not only reduces the insulation performance of the motor, but also easily forms secondary pollution. At the same time, the existing series purification solutions (such as terminal filters or adsorption layers) are subject to the wind pressure limit of the fan and are forced to use low-density filter materials, resulting in frequent problems such as shortened activated carbon adsorption cycle and pores of the filter material being blocked by water molecules. This passive design seriously restricts the overall performance of the system.

[0004] Especially in the typical case of existing subtropical electronic workshops, due to the workshop humidity exceeding 75% and containing organic solvent vapor, the traditional axial flow system cannot simultaneously handle hot and humid air and aerosol pollutants, resulting in increased equipment corrosion rate and health hazards. When the existing transformation plan adds a purification layer to the air outlet, it often fails due to exceeding the fan load limit. It is impossible to achieve deep integration of humidity regulation and gas purification without affecting the airflow drive efficiency. Summary of the invention

[0017] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects: (1) This solution breaks through the limitations of traditional external purification modules by dynamically coupling the rotating adsorption mechanism with the axial flow air duct. The circularly distributed adsorption units are embedded in the air duct shell, and the airflow generated by the impeller drives the cylindrical shell to rotate, thereby realizing the periodic switching of the adsorption and regeneration dual chambers. The symmetrical isolation chamber is precisely positioned under the control of the counterweight system, so that one side of the chamber continues to adsorb moisture and VOCs while the other side of the chamber uses the waste heat of the motor to desorb and regenerate. The increase in wind resistance caused by the series filter material is avoided, and the service life of the active material is significantly extended through the adsorption regeneration cycle mechanism. In particular, it can maintain a stable purification efficiency in high temperature and high humidity environments, solving the technical problems of pore blockage and frequent replacement of filter materials in traditional solutions.

[0018] (2) The environmental adaptability is significantly improved by setting up a composite regeneration system of heat recovery and dynamic flow diversion. The waste heat generated by the operation of the induction motor is directed to the regeneration chamber through the heat conduction mechanism, and combined with the forced convection formed by the air guide slot, efficient desorption of the adsorbent is achieved. The linkage design of the air guide fan blade frame and the stirring mechanism further enhances the uniformity of heat transfer, allowing the regeneration process to be completed under low energy consumption conditions. This active regeneration mechanism not only effectively suppresses the risk of condensation in high humidity environments, but also reduces the system's additional energy consumption through closed-loop thermal management. It is more energy-efficient than traditional electric heating regeneration methods and is particularly suitable for industrial scenarios such as electronic workshops that require continuous dehumidification and purification.

[0019] (3) The position accuracy of the cavity switching is ensured through the synergistic effect of the counterweight system and the magnetic positioning module, while the design of the full-coverage air guide plate and the brush end continuously cleans the air permeable structure during rotation to prevent secondary pollution caused by particle deposition. The feedback control system composed of infrared detection and electromagnetic locking can identify the adsorption saturation state in real time and trigger the regeneration process, so that the equipment can still maintain the optimal working state under unattended conditions, greatly reducing operating costs and downtime risks.

[0024] The following is a detailed description of an axial flow air duct assembly and an axial flow hair dryer provided by the present invention in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are listed as the best and preferred embodiments, and other alternatives can also be used by technicians in some known technical fields; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0025] like Figures 1 to 9 As shown, an embodiment of the present invention provides an axial flow air duct assembly, including an axial flow fan outer casing 1, a plurality of crossbeam frames 3 are fixedly connected to the inner wall of the axial flow fan outer casing 1, and an asynchronous induction motor 4 is fixedly installed at the position of the inner axis of the axial flow fan outer casing 1 through the crossbeam frame 3, an impeller fan 5 is fixedly installed on the output end of the asynchronous induction motor 4, a heat conduction mechanism 6 is sleeved on the outer surface of the asynchronous induction motor 4, and a plurality of groups of adsorption mechanisms 7 are circumferentially arranged on the shell of the axial flow fan outer casing 1 at the position outside the blowing end of the impeller fan 5; The adsorption mechanism 7 includes an outer disc casing 71, and a wind guide outer notch 74 is fixedly installed on the side of the outer disc casing 71 facing the impeller fan 5, and a group of cylindrical casings 77 are movably installed at the inner axis position of each outer disc casing 71, so that the wind generated by the rotation of the impeller fan 5 through the wind guide outer notch 74 drives the cylindrical casing 77 to rotate, and the output ends of the heat conduction mechanism 6 are all extended into the outer disc casing 71 on the same side; Among them, the inner wall of the cylindrical shell 77 is fixedly connected with a partition plate 78, and the cylindrical shell 77 is divided into two groups of symmetrical isolation chambers 711 by the partition plate 78 to respectively fill the adsorption particles, and the heat conducting mechanism 6 extending into the outer disc shell 71 makes one group of adsorption ends in the two groups of symmetrical isolation chambers 711 be used for adsorbing moisture, and the other group of adsorption ends is used for regeneration with the hot air of the heat conducting mechanism 6.

[0026] In order to solve the problem that the existing axial flow fan cannot efficiently handle humidity and pollutants at the same time in a high temperature, high humidity and VOCs-containing environment, the above-mentioned technical solution is adopted to solve the problem. The above-mentioned technical solution is mainly composed of an axial flow fan outer casing 1, an asynchronous induction motor 4, an impeller fan 5, a heat conduction mechanism 6 and an adsorption mechanism 7. The axial flow fan outer casing 1 is a pipe sleeve structure in the prior art, which is an outer shell structure of an axial flow air duct assembly. The configured asynchronous induction motor 4 is an induction motor structure in the prior art. When the induction motor is running, more heat will be generated, especially when the load is high or working at a non-optimal efficiency point, so as to generate more heat to provide a better regeneration environment for the entire system. In addition, the design of the induction motor in the prior art is relatively mature and low in cost, and is suitable for long-term continuous operation. The impeller fan 5 configured on the output end of the motor is a guide fan structure in the prior art, which is a core component of the axial flow fan and is responsible for converting mechanical energy into gas kinetic energy. Since the design of the impeller is crucial to the performance of the fan, the number, shape, angle, etc. of the blades configured therein will affect the airflow characteristics and can be adapted according to different usage environments; The adsorption mechanism 7, which is the core component of the axial flow air duct assembly, includes several groups of outer disc shells 71 and wind-guiding outer notches 74 on the sides of the outer disc shells 71. Each group of outer disc shells 71 is located outside the blowing end of the impeller fan 5 and is arranged in a circular manner around the outer shell 1 of the axial flow fan. A cylindrical shell 77 is movably installed inside each outer disc shell 71. When the asynchronous induction motor 4 drives the impeller fan 5 at its output end to rotate at a high speed, the generated wind force can be guided outward through the axial flow fan outer shell 1 to form an axial flow air duct. On the one hand, the air duct can drive the air flow in the area to complete the axial flow blowing work, and on the other hand, it can also be blown into the air guide outer notch 74 on the side of the impeller fan 5. The high-speed airflow entering the air guide outer notch 74 can blow the cylindrical shell 77 at the axial position inside the outer disc shell 71. Since the inner wall of the cylindrical shell 77 is fixedly connected with a partition plate 78, and the cylindrical shell 77 is divided into two groups of symmetrical isolation chambers 711 under the separation effect of the partition plate 78, adsorption particles are respectively filled in each group of isolation chambers 711, so that one group of adsorption ends in the two groups of symmetrical isolation chambers 711 cooperates with the air duct blown out from the axial flow fan outer shell 1 to adsorb moisture inside the area, and the other group of adsorption ends is used to cooperate with the hot air of the heat conduction mechanism 6 to regenerate the adsorption saturated adsorption particles, so as to achieve the working cycle of the entire axial flow air duct assembly. The adsorption particles configured in each group of isolation chambers 711 have the ability to absorb or adsorb moisture from the air in the prior art. These adsorbents absorb moisture at relatively low temperatures and release moisture at higher temperatures, which is a regeneration process. Silica gel particles are a common adsorbent that has good hygroscopic properties and can be regenerated at relatively low temperatures.

[0027] like Figures 1 to 9 As shown, the inner wall of the cylindrical casing 77 is fixedly connected to the first counterweight block 717 at the positions of the two side ends of the partition plate 78, the inner wall of the cylindrical casing 77 is fixedly connected to the second counterweight block 710 at the position between the two first counterweight blocks 717, and the outer edge of the first counterweight block 717 is hinged with an outer arc flap 726 that can seal against the second counterweight block 710, and a visible cover plate 79 is fixedly installed on the outer disc surface of the cylindrical casing 77, and half of the outer disc casing 71 is located inside the axial flow fan outer casing 1, and the other half is located outside the axial flow fan outer casing 1, and a breathable bottom groove cover 75 is fixedly installed on the outer disc casing 71 at the position inside the axial flow fan outer casing 1.

[0028] Among them, the first counterweight block 717 and the second counterweight block 710 arranged at the outer side of the cylindrical shell 77 constitute a stable counterweight system as a whole, wherein the first counterweight blocks 717 are fixedly connected to the positions at the two side ends of the partition plate 78, and the second counterweight block 710 is fixedly connected to the inner wall of the cylindrical shell 77 at the position between the two first counterweight blocks 717, that is, the second counterweight block 710 is arranged in the middle position of the isolation cavity 711 on each side, and the weight of the second counterweight block 710 is greater than that of the first counterweight block 717. The first counterweight blocks 717 arranged at the two side ends of the partition plate 78 play a stabilizing role, and the heavier second counterweight block 710 has the function of stabilizing the center of gravity. In the process of the cylindrical shell 77 rotating as a whole following the blown air, the cylindrical shell 77 can improve the stability of the centripetal force under the action of the counterweight, so that The rotation is more stable, and further, when the cylindrical sleeve 77 is not rotating, the isolation chambers 711 on both sides store the same adsorption particles. Since the weight of the second counterweight block 710 is much greater than the first counterweight block 717, the side with the second counterweight block 710 will preferentially stop under the influence of gravity, resulting in the isolation chambers 711 on both sides always stopping up and down with the shell of the axial flow fan outer shell 1 as the dividing line when the cylindrical sleeve 77 is not rotating, forming an arrangement state in which half of the isolation chambers 711 on both sides of the cylindrical sleeve 77 are located inside the axial flow fan outer shell 1, and half are located outside the axial flow fan outer shell 1. Specifically, it is to enable the isolation chamber 711 to form a better and more stable one side to perform adsorption work inside the axial flow fan outer shell 1, while the other side of the isolation chamber 711 performs saturation recovery work on the outside of the axial flow fan outer shell 1.

[0029] like Figures 1 to 9As shown, triangular brackets 714 are fixedly connected in the isolation cavities 711 on both sides of the partition plate 78, and a group of stirring brackets 715 are movably installed at the three side corner ends of the triangular brackets 714, and there is a group of stirring brackets 715 facing the second counterweight block 710 on the same side, and first gear columns 716 are fixedly connected on both sides of the axial end of each group of stirring brackets 715, and the outer surfaces of the first gear columns 716 at the three side corner ends of the triangular bracket 714 are meshed with first track sleeves 718.

[0030] Among them, the configured triangular bracket 714 is overall similar to a triangular arrow structure, which is used to movably mount three groups of stirring brackets 715, and the configured first gear column 716 is an axial rod structure with teeth on the outer surface in the prior art, and the corresponding configured first track sleeve 718 is a track structure for engaging the first gear column 716 on the outer side of the three groups of stirring brackets 715, so that the driving axes of the three groups of stirring brackets 715 are engaged on one track.

[0031] like Figures 1 to 9 As shown, the surface of the second counterweight block 710 is provided with a second reserved opening 721 at the position of the first gear column 716 on both sides of the stirring bracket 715, and a movable sleeve 722 is fixedly installed at the middle position of the outer surface of the second counterweight block 710, and a coaxial support rod 723 is movably installed on the surface of the movable sleeve 722, and a fan blade rack 724 is fixedly installed on both sides of the coaxial support rod 723 facing the second reserved opening 721, and a second track sleeve 725 is meshed on the shaft of the fan blade rack 724, and the end of the second track sleeve 725 away from the shaft of the fan blade rack 724 is meshed and sleeved on the first gear column 716 facing the second reserved opening 721.

[0032] Among them, the second reserved sleeve 721 configured on the surface of the second counterweight 710 is, on the one hand, to provide an activity area for the second track cover 725 passing through, so that the second track cover 725 can drive the first gear column 716 facing the second counterweight 710 to rotate along with the rotation of the guide fan blade rack 724, and provide a stable driving force for the three groups of stirring brackets 715. Through the rotation and stirring of the three groups of stirring brackets 715, not only can the particles in the cavity flow, but also through the adsorption performance, the heat can better contact each adsorbed particle in the process of restoring activity, thereby improving the recovery efficiency. On the other hand, the second reserved sleeve 721 configured on the surface of the second counterweight 710 can also cooperate with the rotating guide fan blade rack 724 to press the hot air in the outer disc shell 71 into the isolation cavity 711 in the saturated recovery inside the cylindrical shell 77. In order to ensure the stable operation of the isolation chambers 711 on both sides, ventilation openings are provided on the outer shell surface of the cylindrical shell 77, that is, on the surface of the outer arc flap 726. The overall structure is similar to the breathable bottom groove cover 75, which can better introduce gas and hot air.

[0033] like Figures 1 to 9 As shown, a plurality of groups of full-coverage air guide plates 719 are fixedly connected to the outer surface of the outer arc flap 726 at a position away from the second counterweight block 710, and a plurality of groups of slotted air guide plates 720 are fixedly connected to the outer surface of the outer arc flap 726 at a position close to the second counterweight block 710, and brush ends are arranged on the outer protruding end surfaces of the slotted air guide plates 720 and the full-coverage air guide plates 719, and the brush ends are both attached to one side of the breathable bottom slot cover 75.

[0034] Among them, the configured full-coverage air guide plate 719 and the air guide plate with slots 720 are both air guide wing plate structures in a bent state. The difference is that the full-coverage air guide plate 719 is a whole piece of fully covered air guide wing plate, which can be better rotated by wind force under the action of the wind duct force on the outside, while the air guide plate with slots 720 is different from a whole piece of fully covered air guide wing plate in that a slot is opened in the middle position, and the slot is reserved for the air guide fan blade frame 724. Because the outer disc shell 71 is a cylindrical shape as a whole, that is, the air duct entering from the air guide outer slot 74 will also move in an arc shape. In order to provide the air guide in the middle The fan blade frame 724 provides more wind power, so a slotted air guide plate 720 is configured, and in order to ensure the smooth passage of the air duct in the entire system, a ventilation opening is also opened on the surface of the partition plate 78 located in the middle of each cylindrical shell 77, so that the air duct entering through the air guide outer slot 74 can pass out smoothly, forming a relatively stable air duct path, and the brush end configured on the protruding end surface of the slotted air guide plate 720 and the full-coverage air guide plate 719 is for cleaning the opening on one side of the breathable bottom slot cover 75 with the brush end under the rotation of the cylindrical shell 77 to ensure the stability of the air duct path.

[0035] like Figures 1 to 9 As shown, a magnetic plate 712 is fixedly installed on the outer surface of the cylindrical shell 77 at a position flush with the two first counterweights 717, and an infrared external spotlight 713 is fixedly installed on the side of the magnetic plate 712. A limiting module 76 is also fixedly installed at the side end of the breathable bottom slot cover 75 away from the wind guide outer slot 74, and is aligned with the magnetic plate 712 in a horizontal state of the partition plate 78. The limiting module 76 includes an electromagnetic suction block 761, and an infrared detection block 762 is fixedly installed on the side of the electromagnetic suction block 761.

[0036] Among them, the configured magnetic attraction plate 712 is a plate with magnetic attraction properties as the name suggests, which is used to be adsorbed with the electromagnetic properties of the electromagnetic attraction block 761, and the electromagnetic attraction block 761 is a plate structure in the prior art that can control its magnetic attraction state through electric control. The configured infrared detection block 762 is an electric control device in the prior art that can identify infrared rays and perform servo processing. In the limiting module 76, it serves as a component of the electric control switch, that is, when the infrared external spotlights 713 on both sides of the partition plate 78 are projected onto the detection block on the outer surface of the infrared detection block 762, its detection block can detect the infrared external spotlights 713. When the partition plate 78 is in a horizontal state, the configured infrared external spotlights 713 can be projected onto the infrared detection block 762, so that the infrared detection block 762 opens the electromagnetic attraction block 761 to adsorb the magnetic attraction plate 712 on this side, so as to fix and limit the cylindrical shell 77, so that the cylindrical shell 77 remains in a non-rotating state in this position.

[0037] like Figures 1 to 9 As shown, the present invention also provides an axial flow hair dryer, which is composed of an asynchronous induction motor 4 and an impeller fan 5 at the output end of the asynchronous induction motor 4, the axial flow air duct assembly is installed on the outside of the axial flow hair dryer through a crossbeam frame 3, and the outer surface of the asynchronous induction motor 4 is also fixedly installed with a groove-shaped heat-conducting sleeve 61, the heat-conducting mechanism 6 includes a heat-insulating outer cylindrical sleeve 62 fixedly installed on the outer surface of the groove-shaped heat-conducting sleeve 61, a group of first reserved sleeve openings 63 are opened on the outer edge surface of the heat-insulating outer cylindrical sleeve 62 at a position flush with the outer disc shell 71 on each side, and the outer side of the first reserved sleeve opening 63 on each side is fixedly connected with a heat-insulating outer extension sleeve 64, and the outer protruding ends of the heat-insulating outer extension sleeve 64 extend into the air-guiding outer groove 74 on the same side.

[0038] like Figures 1 to 9As shown, the heat-conducting mechanism 6 also includes an extended heat-conducting rod 66 sleeved in the heat-insulating outer extension sleeve 64 on each side, and a heat-conducting outer slot sleeve plate 65 is fixedly installed on the end of each side of the extended heat-conducting rod 66 close to the asynchronous induction motor 4, and the heat-conducting outer slot sleeve plates 65 are all engaged with the groove-mouth heat-conducting sleeve 61 on the same side, and an open-type threaded heat dissipation sleeve head 67 is fixedly installed on the end of the extended heat-conducting rod 66 away from the heat-conducting outer slot sleeve plate 65, and the open-type threaded heat dissipation sleeve head 67 is located as a whole inside the air guide outer slot 74.

[0039] Among them, the configured grooved heat-conducting sleeve 61, the extended heat-conducting rod 66, the heat-conducting outer groove sleeve plate 65, and the open-ended threaded heat dissipation sleeve head 67 are all made of materials with good thermal conductivity in the prior art, and the configured thermal insulation outer cylindrical sleeve 62 and the thermal insulation outer extension sleeve 64 are all made of materials with good thermal insulation properties in the prior art, which are used to better transport the heat generated by the outer surface of the asynchronous induction motor 4.

[0040] like Figures 1 to 9 As shown, a first hinged sleeve 72 is fixedly installed on the side of the outer disc casing 71 opposite to the breathable bottom slot cover 75, and an outward-turned sealing cover 73 is movably installed through the first hinged sleeve 72. The outward-turned sealing cover 73 is located on the outside of the axial flow fan outer casing 1 as a whole.

[0041] Among them, the configured first hinged sleeve 72 is used to provide a movable axis for the outward-turned sealing cover 73, so that the outward-turned sealing cover 73 can be stably turned outward, and the outward turning of the outward-turned sealing cover 73 can open the outer disc shell 71, which is convenient for the maintenance of the cylindrical shell 77. From the above, it can be known that the outer arc flap 726 is also movably hinged, so it can be opened outward by turning outward to maintain and process the particles inside.

[0042] like Figures 1 to 9 As shown, an auxiliary support hanger 2 is fixedly mounted on the outer surface of the axial flow fan outer shell 1, and the auxiliary support hanger 2 is a hanger that can be adjusted in multiple axial directions.

[0043] The auxiliary support hanger 2 is configured to support and fix the air duct pipes to ensure their stable position and avoid displacement or damage caused by vibration or external forces.

[0044] The working principle provided by the present invention is as follows: When the present invention is used, firstly, the outer disc casing 71 on each side is opened by turning outward the sealing cover 73, and then the cylindrical casing 77 on each side is opened by the outer arc flap 726, and the adsorption particles are poured into the isolation chambers 711 on both sides of the cylindrical casing 77, and then the device is tightened to make each side relatively sealed, and then the device is installed and fixed at a suitable position by using the auxiliary support hanger 2, and the auxiliary support hanger 2 is adjusted so that the air outlet of the outer casing 1 of the axial flow fan is aligned with the area to be treated; Then, under the action of the second counterweight block 710 and the first counterweight block 717 on each side of the cylindrical casing 77, the partition plate 78 of the cylindrical casing 77 on each side is aligned with the limiting module 76, and the signal of the infrared external spotlight 713 is received through the infrared detection block 762 of the limiting module 76, and the electromagnetic suction block 761 is turned on to adsorb and fix the magnetic suction plate 712, so that one side of the isolation cavity 711 of the cylindrical casing 77 is located inside the axial flow fan outer casing 1, and the other side is located outside the axial flow fan outer casing 1. The adsorbed particles in the isolation cavity 711 inside the axial flow fan outer casing 1 can cooperate with the air duct generated by the impeller fan 5 at the output end of the asynchronous induction motor 4 to purify and adsorb the air in the area; Then, as the adsorption work proceeds, the adsorbed particles in the isolation chamber 711 inside the axial flow fan outer shell 1 will reach the state of adsorption saturation. At this time, the electromagnetic suction block 761 is turned off by the electric control signal, and the adsorption state is released. Under the influence of wind, the cylindrical shell 77 will rotate. When the cylindrical shell 77 is docked again by controlling the blowing state, it is only necessary to configure the infrared external spotlights 713 on both sides of the cylindrical shell 77 with spotlight signals of different frequencies to cooperate with the adsorption effect of the electromagnetic suction block 761 and the magnetic suction plate 712, so as to accurately dock the isolation chambers 711 on both sides. Specifically, the isolation chambers originally inside the axial flow fan outer shell 1 When 711 is in the adsorption saturation state, the isolation chamber 711 on the other side can be switched to replace the saturated isolation chamber 711 with the isolation chamber 711 on the other side. After the process, the saturated isolation chamber 711 is located outside the outer casing 1 of the axial flow fan. At this time, after the cylindrical casing 77 is fixed by the limiting module 76, the asynchronous induction motor 4 can be turned on again to work, so that the heat generated by the impeller fan 5 at the output end of the asynchronous induction motor 4 and the heat generated by the outer surface are introduced into the outer disc casing 71 from the air guide outer notch 74 through the heat conduction mechanism 6, so as to heat the saturated isolation chamber 711 at a high temperature, and promote the activity recovery of the adsorption particles in the saturated isolation chamber 711. Finally, if the isolation cavities 711 on both sides are saturated and difficult to recover through high temperature, and the efficiency of high temperature recovery is extremely low, the adsorption particles can be replaced by opening the outward sealing cover 73 and the outer arc flap 726 again.
