A portable towel drying rack

Abstract

This utility model discloses a portable towel drying rack, including a support column and a fan. The support column is a hollow column structure, and the fan is installed inside the support column to divide the interior of the support column into an air outlet duct and an air inlet duct. The support column has an air inlet and an air outlet, so that when the fan is turned on, the airflow can enter the air inlet duct from the outside environment through the air inlet, and then enter the air outlet duct from the air inlet duct. The airflow in the air outlet duct blows onto the towel draped on the support column through the air outlet and returns to the outside environment, thus forming an airflow circulation. By integrating the fan into the hollow support column and using a single column structure to separate the air inlet and air outlet ducts, this design directly and clearly defines the airflow circulation path, eliminating the need for external air ducts and multi-part assembly structures of traditional portable towel drying racks. It is convenient for travel or daily storage, and the product is small, lightweight, occupies little space, and is easy to use.

Description

Technical Field

[0001] This utility model relates to the field of towel rack technology, and in particular to a portable air-drying towel rack. Background Technology

[0002] Towels are a common household item, used almost daily. In daily life, after using a towel, people usually hang it to dry on a towel rack in the bathroom or washroom. However, bathrooms and washrooms are typically damp and poorly ventilated, making it difficult for towels to dry completely, often leaving them damp for extended periods. Prolonged dampness can breed bacteria, potentially harming people's health.

[0003] However, the airflow path of the existing towel rack structure is not accurate enough. The operation of the fan will cause the airflow direction inside the rack to be turbulent. As a result, the airflow discharged from some vents will interfere with and cancel out the airflow drawn in from other vents, which will greatly weaken the direct effect of the airflow on the towel. The original drying function is thus greatly reduced, the drying time is extended, and even after long-term operation, some areas may still be damp. The drying effect is poor and cannot meet the needs of users. In addition, the existing towel rack structure is relatively complex, bulky, and occupies a lot of space. It is inconvenient to carry and use and cannot meet the needs of travel and other usage scenarios. Utility Model Content

[0004] The purpose of this utility model is to provide a portable towel drying rack, which aims to at least solve the technical problems of existing towel drying racks being inconvenient to carry when going out due to their complex structure and large size.

[0005] To achieve the above objectives, in a first aspect, the technical solution of this utility model provides a portable towel drying rack, comprising:

[0006] Support column, which is a hollow column structure, is used to support the towel;

[0007] A fan is installed inside the support column to divide the interior of the support column into an air outlet duct and an air inlet duct, wherein the air outlet duct is located on the air outlet side of the fan and the air inlet duct is located on the air inlet side of the fan.

[0008] The support column is provided with at least one air inlet and one air outlet. The air inlet connects the air intake duct to the external environment, and the air outlet connects the air outlet duct to the external environment. When the fan is started, airflow can enter the air intake duct from the external environment through the air inlet, and then enter the air outlet duct. The airflow in the air outlet duct blows through the air outlet onto the towel draped on the support column and returns to the external environment, thus forming an airflow circulation.

[0009] Furthermore, multiple air outlets are provided, and the multiple air outlets are spaced apart along the circumferential and / or length direction of the support column; and / or

[0010] The air outlet is a long, narrow slot structure that extends along the length of the support column.

[0011] Furthermore, it also includes a fixing structure, which is disposed on one end face of the support column near the air inlet, so as to install the support column on the mounting surface in a generally horizontal or vertical direction through the fixing structure.

[0012] Furthermore, the fixing structure is a vacuum suction cup, which includes an adsorption surface and a connecting surface. The connecting surface is connected to one end face near the air inlet so that the support column can be fixed by adsorbing onto the mounting surface through the adsorption surface.

[0013] And / or, the fixing structure is an adhesive strip, which is used to fix the support column by adhering it to the mounting surface.

[0014] Furthermore, the support column includes a frame and a clamping member, with one end of the frame rotatably mounted on the clamping member;

[0015] A connector is provided at the center of the connecting surface. The connector passes through the clamping member and is connected to the frame. The frame can rotate to a first position and a second position. When the frame rotates from the second position to the first position, the frame can drive the connector to pull away from the mounting surface. The reaction force of the connector can cause the clamping member to press the outer peripheral edge of the vacuum suction cup against the mounting surface, so that a negative pressure chamber is formed between the vacuum suction cup and the mounting surface. When the frame rotates from the first position to the second position, the frame releases the connector, allowing the vacuum suction cup to detach.

[0016] Furthermore, multiple air outlets are disposed on the outer peripheral surface of the air outlet duct, and the air inlet is disposed on the side of the support column near the fixed structure.

[0017] Furthermore, the air inlet is provided in multiple ways, and the multiple air inlets are spaced apart circumferentially on the outer peripheral surface of the air inlet duct, such that when the support column is installed on the mounting surface in the horizontal direction, at least one of the air inlets is located on the lower side of the support column.

[0018] Furthermore, it also includes a control module. The support column has a receiving cavity inside one end near the air inlet. The receiving cavity is separated from the air inlet duct by a partition. The control module is installed in the receiving cavity and is electrically connected to the fan to control the start and stop of the fan and / or the power level.

[0019] Alternatively, it may also include a control module and a power supply. The support column has an internal cavity at the end near the air inlet. The control module is installed in the cavity and is electrically connected to the fan to control the fan's start / stop and / or power level. The support column has a housing on its side at the end near the air inlet. The power supply is housed in the housing and is electrically connected to the control module.

[0020] Furthermore, the fan blades are arranged to rotate around the central axis of the support column.

[0021] On the other hand, this application also provides a portable towel drying rack, the solution of which includes:

[0022] The support column is a hollow column structure, and is used to support the towel. At least one air inlet is provided on the support column.

[0023] A fan is installed inside the support column to divide the interior of the support column into an air outlet duct and an air inlet duct. The air outlet duct is located on the air outlet side of the fan, and the air inlet duct is located on the air inlet side of the fan. An air outlet is provided on the air outlet duct.

[0024] A vacuum suction cup is disposed on one end face of the support column near the air inlet; the support column is fixed by adhering to the mounting surface through the vacuum suction cup.

[0025] As can be seen from the above technical solution, the portable towel drying rack of this utility model integrates the fan into the hollow support column, and uses a single columnar structure to separate the air inlet and outlet ducts. By opening the air outlet on the support column, the circulation path of the airflow is clearly defined. This eliminates the need for external air ducts and multi-part assembly structures of traditional portable towel drying racks. The towel can be dried by simply placing it on the support column and letting the air blown by the fan. This reduces the overall structure and volume of the product, making it compact, lightweight, and space-saving. It is convenient to carry and use, and easy to carry or store for travel or daily life. Furthermore, the support column can be fixed horizontally or vertically to adapt to different spatial layouts.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] For ease of understanding, this application will compare... Figure 1 As shown in the illustration, the observer faces the attached... Figure 1 When making observations, the left side of the observer is designated as left, the right side of the observer as right, the front of the observer as back, the back of the observer as front, the top of the observer as up, and the bottom of the observer as down. It should be noted that the terms "front end", "rear end", "left side", "right side", "middle", "above", and "below" in the text indicate the orientation or positional relationship based on the accompanying drawings. They are only for the purpose of clearly describing this utility model and do not indicate or imply that the structure or component referred to must have a specific orientation or be constructed in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] Please refer to the following: Figures 1 to 12This embodiment provides a portable towel drying rack, including a support column 100 and a fan 200. The support column 100 is a hollow column structure used to drape towels. The fan 200 is installed inside the support column 100 to divide the interior of the support column 100 into an air outlet duct 110 and an air inlet duct 120. The air outlet duct 110 is located on the air outlet side of the fan 200, and the air inlet duct 120 is located on the air inlet side of the fan 200. At least one air inlet is provided on the support column 100. 140 and 130 are connected to the external environment through the air inlet 140 and the air outlet 130, so that when the fan 200 is started, the air flow can enter the air inlet 120 from the external environment through the air inlet 140, and then enter the air outlet 110 from the air inlet 120. The air flow in the air outlet 110 is blown through the air outlet 130 onto the towel draped on the support column 100 and returns to the external environment, thus forming an airflow circulation.

[0048] As can be seen, the portable towel rack of this embodiment integrates the fan 200 into the hollow support column 100, and uses a single column structure to separate the air inlet duct 120 and the air outlet duct 110. By opening the air outlet 130 on the support column 100, the circulation path of the airflow is clearly defined. This eliminates the need for external air ducts and multi-part assembly structures of traditional portable towel racks, reduces the overall volume, and makes it easy to disassemble and carry. It is convenient for travel or daily storage. Furthermore, the support column 100 can be fixed horizontally or vertically to adapt to different spatial layouts.

[0049] In this embodiment, a complete airflow path is constructed through the clearly defined air inlet duct 120 and air outlet duct 110. That is, outside air enters the air inlet duct 120 from the air inlet 140, enters the air outlet duct 110 after being acted upon by the fan 200, and finally blows towards the towel from the air outlet 130 and returns to the outside environment, forming a unidirectional and complete airflow cycle. This airflow cycle design allows outside air to continuously and stably contact the towel, thereby efficiently removing moisture from the surface of the towel. The airflow carrying moisture is finally discharged from the air outlet 130 and returns to the outside environment, without forming water vapor accumulation inside the device. This ensures the dryness of the towel during the drying process and reduces the dampness of the device, so that the drying efficiency of the towel is not affected by the reduced structure of the portable towel drying rack, and the towel can still be dried efficiently.

[0050] Specifically, the inner diameter of the support column 100 is approximately equal to the outer diameter of the fan blades of the fan 200. The gap between the edge of the fan blades and the inner wall of the support column 100 is small, and the fan blades of the fan 200 will not contact the inner wall of the support column 100 when rotating. This avoids the formation of vortices or useless circulation of some airflow inside due to excessive gaps, thereby improving airflow utilization and air delivery efficiency. The fan 200 can be fixed inside the support column 100 by screws.

[0051] In this embodiment, as Figures 1 to 4 As shown, multiple air outlets 130 are provided, and the multiple air outlets 130 are spaced apart along the circumferential and length directions of the support column 100. The air outlet 130 is a long strip-shaped slot structure that extends along the length direction of the support column 100.

[0052] Multiple air outlets 130 are spaced apart along the circumference and length of the support column 100, allowing air to be blown onto different parts of the towels hanging on the support column 100 from different circumferential directions, thus avoiding the problem of insufficient drying in certain areas. The multiple air outlets 130 are spaced apart along the length and extend along the length, so that the air outlets 130 cover a wider range. Whether it is a small face towel or a large bath towel, it can achieve a good drying effect after being hung. It is highly practical. It is understood that the towels referred to in this article include, but are not limited to, bath towels, face towels, and hand towels.

[0053] In this embodiment, as Figures 1 to 8 As shown, it also includes a fixing structure, which is set on the end face of the support column 100 near the air inlet 140, so as to install the support column 100 on the mounting surface in a generally horizontal or vertical direction through the fixing structure.

[0054] The installation surface includes, but is not limited to, the ground, tabletop, wall, or tile surface. When installed vertically, the support column 100 can be installed on the ground or tabletop to form a vertical frame structure, breaking the limitation of the fixed installation direction of traditional towel racks. When installed horizontally, the support column 100 can keep the hanging towels in a relatively stable posture, avoiding the towels from stacking, sticking, or even slipping off due to the swaying of the bracket. The design of being able to be installed vertically or horizontally allows users to choose the installation method flexibly during outdoor travel. Vertical installation can be used when there is little horizontal space, and horizontal installation can be used when there is little vertical space, so as to reduce the occupation of environmental space and make it convenient for users to use.

[0055] In this embodiment, as Figure 1 and Figure 8As shown, the fixing structure is a vacuum suction cup 300. The vacuum suction cup 300 includes an adsorption surface 310 and a connecting surface 320. The connecting surface 320 is connected to the end face near the air inlet 140 so that it can be adsorbed onto the mounting surface through the adsorption surface 310 to fix the support column 100. The vacuum suction cup 300 is fixed on the mounting surface by the principle of negative pressure adsorption, without the need to drill holes, nail, or use adhesives on the mounting surface, thus avoiding permanent damage to the mounting surface.

[0056] Preferably, the adsorption surface 310 is provided with adhesive, which is an improved version of the suction cup. The surface of the suction cup has self-adhesive adhesive, which can play a dual role of adhesion and adsorption when used. The adhesion effect is good, and its connection strength is sufficient to support the support column 100 and the towel draped on the support column 100.

[0057] In one possible implementation, the fixing structure is an adhesive strip, which is used to fix the support column 100 by adhering it to the mounting surface. The adhesive surface of the adhesive strip has self-adhesive drip to achieve the bonding effect.

[0058] In other embodiments, the fixing structure can use screws, and the support column 100 can be installed by welding mounting plates to one end of the support column 100, the mounting plates being provided with mounting holes spaced apart circumferentially, so as to drive the screws through the mounting holes into the mounting surface.

[0059] In this embodiment, as Figures 3 to 8 and Figures 11 to 12 As shown, the support column 100 includes a frame 150 and a clamping member 160. One end of the frame 150 is rotatably mounted on the clamping member 160. A connector 330 is provided at the middle position of the connecting surface 320. The connector 330 passes through the clamping member 160 and is connected to the frame 150. The frame 150 can rotate to a first position and a second position. When the frame 150 rotates from the second position to the first position, the frame 150 can drive the connector 330 to pull up in a direction away from the mounting surface. The reaction force of the connector 330 can cause the clamping member 160 to press the outer peripheral edge of the vacuum suction cup 300 tightly against the mounting surface, so that a negative pressure chamber is formed between the vacuum suction cup 300 and the mounting surface. When the frame 150 rotates from the first position to the second position, the frame 150 releases the connector 330, allowing the vacuum suction cup 300 to detach.

[0060] The connector 330 is pulled up to form a closed negative pressure chamber between the vacuum suction cup 300 and the mounting surface. The reaction force of the connector 330 also presses the clamping member 160 against the outer edge of the vacuum suction cup 300, effectively preventing external air from entering between the vacuum suction cup 300 and the mounting surface. This dual effect significantly enhances the suction strength of the suction cup, ensuring that the support column 100 is not easily dislodged when the towel is suspended or the fan 200 vibrates during operation, thus guaranteeing safety. The vacuum suction cup 300 can be fixed and released simply by rotating the frame 150 between the first and second positions, without the need for additional tools. Users do not need complicated installation steps; whether it is initial installation or subsequent position adjustments, it can be easily completed, greatly reducing the barrier to entry.

[0061] Specifically, the clamping member 160 is provided with a rotating connection part 161, and one end of the frame 150 is provided with a first pivot 153, so that the frame 150 can be rotatably mounted on the clamping member 160 by installing the first pivot 153 into the rotating connection part 161.

[0062] Furthermore, such as Figures 3 to 8 and Figures 11 to 12 As shown, the frame 150 includes a connecting block 151 and a body 152. The connecting block 151 includes a first end and a second end disposed opposite to each other. The first end is provided with a second pivot 151a, which is rotatably connected to the body 152. The second end is provided with a third pivot 151b and a fourth pivot 151c. The third pivot 151b is rotatably connected to a clamping member 160, and the fourth pivot 151c is rotatably connected to a connecting member 330. The second end protrudes towards the clamping member 160 to form abutment protrusion 151d, so that the connecting block 151 has a "7" shaped structure. The body 152 has a first sliding groove 152a along the vertical direction, and the second pivot 151a can slide up and down in the first sliding groove 152a. The clamping member 160 has a second sliding groove 162 along the horizontal direction. The third pivot 151b can slide left and right in the second sliding groove 162. When the frame 150 rotates from the second position to the first position, the second pivot 151a slides downward and the third pivot 151b slides to the right, so as to drive the connector 330 to translate to the right, so as to form a negative pressure chamber between the vacuum suction cup 300 and the mounting surface. At the same time, the connecting block 151 abuts against the clamping member 160. The reaction force of the connector 330 causes the clamping member 160 to press the outer peripheral edge of the vacuum suction cup 300. In the second position, the second pivot 151a slides upward and the third pivot 151b slides to the left, so as to drive the connector 330 to translate to the left, so as to make the negative pressure chamber between the vacuum suction cup 300 and the mounting surface disappear. At the same time, the clamping member 160 will also release the suction cup assembly, achieving a detachable effect.

[0063] The clamping member 160 is provided with a clearance hole 163, and the connecting member 330 passes through the clearance hole 163 and is rotatably connected to the fourth pivot 151c.

[0064] In this embodiment, as Figures 2 to 11 As shown, it also includes a first opening 170, which is located on the lower side of the air outlet duct 110. One end of the first opening 170 extends from one end of the air outlet duct 110 to the other end. The through-type first opening 170 at the bottom of the air outlet duct 110 allows air to be directly supplied to the bottom area of ​​the towel suspended below the support column 100 when the support column 100 is installed horizontally. Since moisture tends to accumulate more easily at the bottom of the towel when it is hung, the first opening 170 can specifically enhance the airflow to the bottom of the towel, achieving more uniform and faster drying of the towel.

[0065] In this embodiment, multiple air outlets 130 are disposed on the outer peripheral surface of the air outlet duct 110, and an air inlet 140 is disposed on the side of the support column 100 near the fixed structure. The air inlet 140 is disposed on the side of the support column 100 near the fixed structure, forming a spatially staggered layout with the air outlets 130 located on the outer periphery of the air outlet duct 110, thereby improving the effectiveness of airflow circulation.

[0066] In this embodiment, as Figures 2 to 4 As shown, multiple air inlets 140 are provided, and these multiple air inlets 140 are spaced apart circumferentially on the outer peripheral surface of the air intake duct 120. When the support column 100 is installed horizontally on the mounting surface, at least one air inlet 140 is located on the lower side of the support column 100. This arrangement avoids the problem of towel obstruction from the source. It can be understood that when the support column 100 is installed horizontally, when the user hangs a towel, the towel will naturally fall mainly on the side peripheral surface of the support column 100 and will not cover the lower area. This eliminates the possibility of towel obstruction from the spatial layout, which does not affect the user's daily habits and ensures that the air intake is always unobstructed, avoiding the hidden dangers of reduced equipment operating efficiency, increased energy consumption, or even local overheating caused by insufficient air intake.

[0067] In this embodiment, as Figures 1 to 4 As shown, it also includes a control module 400. The support column 100 has a housing cavity inside the end near the air inlet 140. The housing cavity is separated from the air inlet duct 120 by a partition. The control module 400 is installed in the housing cavity and is electrically connected to the fan 200 so as to control the start and stop and the power of the fan 200.

[0068] The support column 100 includes a body and a cover. The cover is threadedly connected to the body. A partition is detachably installed in the cover via a snap-fit. The fan 200 is fixedly connected to the inner wall of the body. The output shaft of the fan 200 extends away from the cover. Fan blades are mounted on the output shaft of the fan 200. A wire hole is provided on the partition. The control module 400 is electrically connected to the fan 200 through the wire hole. A wire outlet hole is also provided on the cavity wall of the accommodating cavity. The power supply module is also included, which supplies power to the fan 200 and the control module 400 through the wire outlet hole. The fan 200 adopts a fan of the prior art. The remaining structure and electrical connections of the fan 200 are prior art and will not be described further here as they are not the focus of this invention. The control module 400 includes a button unit, allowing the user to control the start and stop of the fan 200 by pressing different buttons. The user can also flexibly adjust the power of the fan 200 according to the dryness of the towel, that is, adjust the wind force of the fan 200. When using a wet towel, a strong wind is used to dry it quickly, while a weak wind is used to save energy for a slightly damp towel, meeting the needs of different scenarios and making the operation more user-friendly. The control module 400 has a waterproof shell, preventing water from the towel and humid air from penetrating the control module 400. The circuit of the control module 400 is existing technology, and since it is not the protection point of this application, it will not be described in detail here.

[0069] Other possible implementations include a control module 400 and a power supply. The support column 100 has a housing cavity at the end near the air inlet 140. The control module 400 is installed in the housing cavity and is electrically connected to the fan 200 to control the start / stop and power of the fan 200. The support column 100 has a box on the side near the air inlet 140. The power supply is housed in the box and is electrically connected to the control module 400.

[0070] The housing and the accommodating cavity are connected by a connecting hole. The power supply provides power to the control module 400 through the connecting hole. The wires of the fan 200 are passed through the accommodating cavity so that the control module 400 and the fan 200 are electrically connected. The fan 200 draws power from the power source through the connecting hole. In this embodiment, the power source is a dry cell battery. The housing includes a shell and a cover. The cover is detachably installed on the shell so that the dry cell battery can be replaced by removing the cover. In other embodiments, the power source can also be a rechargeable lithium battery, etc.

[0071] In this embodiment, as Figure 10As shown, the fan blades of the fan 200 are arranged to rotate around the central axis of the support column 100. When the fan blades rotate around the central axis of the support column 100, the generated airflow can be evenly diffused along the length of the hollow column support. The support column 100 is hollow columnar, and its central axis and inner wall form a natural flow path. When the fan blades rotate around this axis, the airflow can flow smoothly along the inner wall of the column, reducing the resistance and turbulence caused by friction and collision between the airflow and the inner wall of the support.

[0072] In addition, in a second aspect, this application also provides a portable towel drying rack, the key features of which include a support column 100, a fan 200, and a vacuum suction cup 300. The support column 100 is a hollow column structure used to support towels. The fan 200 is installed inside the support column 100 to divide the interior of the support column 100 into an air outlet duct 110 and an air inlet duct 120. The air outlet duct 110 is located on the air outlet side of the fan 200, and the air inlet duct 120 is located on the air inlet side of the fan 200. An air outlet 130 is provided on the air outlet duct 110. The vacuum suction cup 300 is disposed on the end face of the support column 100 near the air inlet 140 to fix the support column 100 by adhering it to the mounting surface.

[0073] By integrating the fan 200 into the hollow support column 100, the air inlet duct 120 and air outlet duct 110 are separated by a single columnar structure. An air outlet 130 is provided on the support column 100. This design directly defines the airflow circulation path, eliminating the need for external ducts and multi-part assembly structures found in traditional portable towel racks. This reduces the overall size, making it easier to disassemble and carry, and convenient for travel or daily storage. The vacuum suction cup 300 serves as a fixing device, directly mounted on the end face of the support column 100. The mounting surface includes, but is not limited to, the ground, tabletop, and wall. When installed vertically on a surface such as a flat or tiled surface, the support column 100 can be mounted on the ground or tabletop to form a vertical frame structure 150, breaking the limitation of the fixed installation direction of traditional towel racks. When installed horizontally, the support column 100 can keep the hanging towels in a relatively stable posture, preventing the towels from stacking, sticking, or even slipping due to the swaying of the bracket. The design that can be installed vertically or horizontally allows users to choose flexibly during outdoor travel. Vertical installation can be used when there is a large vertical space, and horizontal installation can be used when there is a large horizontal space, so as to reduce the occupation of environmental space and make it convenient for users to use.

[0074] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0075] This portable towel drying rack integrates a fan 200 into a hollow support column 100, using a single columnar structure to separate the air inlet duct 120 and the air outlet duct 110. By opening an air outlet 130 on the support column 100, the air circulation path is clearly defined. This eliminates the need for external air ducts and multi-part assembly structures found in traditional portable towel drying racks, reducing the overall size and making it easy to disassemble and carry. It is convenient for travel or daily storage, and the support column 100 can be fixed horizontally or vertically to adapt to different spatial layouts.
