Description

Technical Field

[0001] This utility model relates to the field of shoe dryer technology, and in particular to a single-fan, dual-duct shoe dryer. Background Technology

[0002] Shoe dryers, as common daily household items, are widely used in drying, deodorizing, and sterilizing shoes. Traditional shoe dryers mostly adopt a single-fan, single-duct design, meaning that hot air is blown into the body of one shoe through a single fan and an air outlet. While this design is simple in structure, it can only process one shoe at a time, resulting in low efficiency and failing to meet the user's need to dry two shoes simultaneously. Furthermore, some existing technologies attempt to adopt a dual-fan, dual-duct solution, using two independent fans to dry two shoes respectively. However, this design increases manufacturing costs, energy consumption, and structural complexity, and may also lead to uneven airflow due to differences in fan performance, affecting the drying effect.

[0003] Therefore, it is necessary to provide a single-fan, dual-duct shoe dryer to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this invention is to provide a single-fan, dual-duct shoe dryer, which aims to solve the problem of how to simultaneously and efficiently dry two shoes without increasing the number of fans or costs, while ensuring uniform airflow distribution.

[0005] To achieve the above objectives, this utility model provides a single-fan, dual-duct shoe dryer, comprising: A housing having a accommodating cavity, the housing having an air inlet communicating with the accommodating cavity and two air outlets; Two support frames are respectively connected to a predetermined position on the top of the shell, and each support frame is used to extend into the shoe body to fix the shoe body; Two air guide nozzles, each of which is connected to the corresponding air outlet, and the end of the air guide nozzle away from the air outlet extends into the shoe body supported by the corresponding support frame; A blower assembly is disposed within the accommodating cavity and includes a main air duct, a fan disposed within the main air duct, and two air outlet channels simultaneously connected to the end of the main air duct away from the fan. Each air outlet channel is connected to one of the air outlet holes. The fan is used to blow air simultaneously into the two air outlet channels through the main air duct.

[0006] In a preferred embodiment, the main air duct includes a fan housing and a diversion cavity communicating with the fan housing; the fan is disposed inside the fan housing; the fan housing is provided with a ventilation opening communicating with the receiving cavity.

[0007] In a preferred embodiment, a flow divider is provided on the side of the flow divider cavity near the fan housing; the fan includes a motor and a rotating plate connected to the motor, and a ring of fan blades is symmetrically provided on the left and right sides of the rotating plate, and the rotating plate and the flow divider are located on the same plane.

[0008] In a preferred embodiment, a check valve is provided on the side of the flow divider cavity away from the fan casing; the check valve and the flow divider are located on the same plane.

[0009] In a preferred embodiment, each of the air outlets has a locking block on its inner wall, and one end of the air guide nozzle has a buckle that matches the locking block; the locking block and the buckle engage to engage one end of the air guide nozzle with the corresponding air outlet.

[0010] In a preferred embodiment, each of the air outlets has a filter screen on its inner wall.

[0011] In a preferred embodiment, the air guide nozzle gradually bends in the direction close to the corresponding support frame, and the cross-sectional area of ​​the air guide nozzle continuously decreases from the end close to the housing to the end away from the housing.

[0012] In a preferred embodiment, each of the support frames includes an elliptical rod and a support plate; the housing is provided with an elliptical slot adapted to the elliptical rod; one end of the elliptical rod is inserted into the corresponding elliptical slot; the support plate is inclined downward and connected to the end of the elliptical rod away from the elliptical slot, and the support plate has at least one through hole.

[0014] In a preferred embodiment, the housing has a plurality of support pads on the side away from the air guide nozzle; the air inlet is located on the side of the housing away from the air guide nozzle.

[0015] This utility model provides a single-fan, dual-duct shoe dryer. A single fan is located within the main duct, simultaneously distributing airflow to two outlet channels.

Detailed Implementation

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are merely for explaining the present utility model and are not intended to limit the present utility model.

[0020] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0021] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0022] In an embodiment of this utility model, a single-fan dual-duct shoe dryer 100 is provided to accelerate the drying rate of shoes by blowing air into the inside of the shoes.

[0023] like Figures 1-6 As shown, the single-fan dual-duct shoe dryer 100 includes: a housing 10 with a receiving cavity 101, two support frames 20, two air guide nozzles 30, and a blowing assembly 40.

[0024] The housing 10 may be generally rectangular or cylindrical, and it has an air inlet 102 communicating with the accommodating cavity 101 and two air outlets 103. The air inlet 102 may be a dot array of micropores or small pores, which can both realize the function of air intake and prevent larger external debris from entering the accommodating cavity 101 through the air inlet 102. Furthermore, each air outlet 103 has a filter screen 11 on its inner wall, thereby preventing external debris from entering the accommodating cavity 101 through the air outlet 103.

[0025] Combination Figure 1 and Figure 3 As shown, two support frames 20 are respectively connected to preset positions on the top of the housing 10. Each support frame 20 is used to extend into the interior of a shoe body to secure it. Typically, the opening of the shoe body is placed downwards, with the support frame 20 extending into the side near the toe and the air vent 30 extending into the side near the heel.

[0026] Specifically, each support frame 20 includes an elliptical rod 21 and a support plate 22. Correspondingly, the housing 10 is provided with an elliptical slot 104 adapted to the elliptical rod 21. One end of the elliptical rod 21 is inserted into the corresponding elliptical slot 104, which also serves as a foolproof installation method. The support plate 22 is inclined downwards and connected to the end of the elliptical rod 21 away from the elliptical slot 104, thus extending into the shoe body to expand the interior of the shoe body and prevent the shoe body from shrinking inwards when supported by the support frame 20, thereby improving the drying effect. The downward inclination of the support plate 22 also allows the shoe body to be tilted, facilitating the drainage of significant moisture from the shoe body. Furthermore, the support plate 22 has at least one through hole 201 to prevent the support plate 22 from dividing the interior of the shoe body into different areas and creating numerous airflow dead zones, promoting air circulation inside the shoe body and ensuring uniform drying throughout the shoe body.

[0027] Combination Figure 1 and Figure 3 As shown, each air guide nozzle 30 is connected to the corresponding air outlet 103, and the end of the air guide nozzle 30 away from the air outlet 103 extends into the shoe body supported by the corresponding support frame 20. Therefore, the air blown out from the air outlet 103 will be blown into the shoe body through the air guide nozzle 30.

[0028] Each air outlet 103 has a locking block 12 on its inner wall. One end of the air guide nozzle 30 has a buckle 31 that matches the locking block 12. The locking block 12 and the buckle 31 engage to engage one end of the air guide nozzle 30 with the corresponding air outlet 103. The edge of the connection between the air guide nozzle 30 and the air outlet 103 can be made airtight through structural fit.

[0029] Furthermore, the air guide nozzle 30 gradually bends along the direction close to the corresponding support frame 20 to roughly form an arc shape, thereby facilitating its insertion into the shoe body hanging on the support frame 20. The cross-sectional area of ​​the air guide nozzle 30 continuously decreases from the end close to the housing 10 to the end away from the housing 10, thereby increasing the air outlet speed.

[0030] Combination Figures 2-4As shown, the blower assembly 40 is disposed within the receiving cavity 101 and includes a main air duct 401, a fan 41 disposed within the main air duct 401, and two air outlet channels 402 simultaneously connected to the end of the main air duct 401 away from the fan 41. Each air outlet channel 402 is connected to a corresponding air outlet 103, thereby drying one shoe. The fan 41 is used to blow air simultaneously through the main air duct 401 into the two air outlet channels 402, so that the generated airflow is evenly distributed to the two independent air outlet channels 402, ensuring that both shoes are dried simultaneously.

[0031] Specifically, the main air duct 401 includes a fan housing 42 and a distribution chamber 403 communicating with the fan housing 42. A fan 41 is housed within the fan housing 42. Correspondingly, the fan housing 42 has a vent 404 communicating with the receiving cavity 101, allowing the fan 41 to draw air from the outside through the vent 404, the receiving cavity 101, and the air inlet 102. The left and right sides of the distribution chamber 403 are respectively connected to two air outlet channels 402. The central axis of the distribution chamber 403 and the central axis of the air outlet channels 402 are nearly perpendicular at their intersection.

[0032] Furthermore, a flow divider 43 is provided on the side of the flow divider 403 near the fan housing 42. The fan 41 includes a motor 411 and a rotating plate 412 connected to the motor 411. A ring of fan blades 413 is symmetrically provided on each of the left and right sides of the rotating plate 412, and the rotating plate 412 and the flow divider 43 are located on the same plane. That is, the two rings of fan blades 413 respectively provided on both sides of the rotating plate 412 are also located on both sides of the flow divider 43. Therefore, the airflow generated when the two rings of fan blades 413 are driven passes evenly on both sides of the flow divider 43, so that the airflow in the main air duct 401 is evenly divided into two parts by the flow divider 43, ensuring that the airflow to the two air outlet ducts 402 is as consistent as possible.

[0033] Furthermore, a check valve 44 is provided on the side of the diversion cavity 403 away from the fan casing 42. The check valve 44 and the diversion valve 43 are located on the same plane. Therefore, the check valve 44 is located at the end of the main air duct 401, and its two sides are respectively opposite to the starting ends of the two air outlet channels 402. It can not only divert the air from the main air duct 401 to the two air outlet channels 402, but also prevent the backflow of the air entering the two air outlet channels 402 from forming strong turbulence, thereby improving the air outlet effect of the main air duct 401.

[0034] like Figure 1 and Figure 3 As shown, the housing 10 is recessed inward at the location between the air guide nozzle 30 and the support frame 20 to form a strip-shaped groove 105. The length direction of the strip-shaped groove 105 is parallel to the line connecting the two air guide nozzles 30. Therefore, the strip-shaped groove 105 is located below the shoe opening on the support frame 20, increasing the air outlet distance of the airflow sprayed downward from the shoe opening and promoting the overall airflow effect.

[0035] like Figure 2 As shown, several support blocks 13 are provided on the side of the housing 10 away from the air guide nozzle 30. The air inlet 102 is located on the side of the housing 10 away from the air guide nozzle 30. The support blocks 13 can both raise the bottom of the housing 10 to ensure the air intake effect of the air inlet 102 and absorb the vibration of the fan 41 during operation, thereby reducing operating noise.

[0036] It should be noted that the blower assembly 40 may also include a heating element (not shown in the figure), so that the blower 41 blows out hot air, further improving the drying effect. The specific structure and implementation principle of the heating element can be found in the prior art, and will not be described in detail here.

[0037] In summary, the single-fan dual-duct shoe dryer 100 provided by this utility model employs a single fan 41 located within a main duct 401. The main duct 401 simultaneously distributes airflow to two outlet channels 402. Each outlet channel 402 is connected to an air outlet 103, and, in conjunction with an air guide nozzle 30, directly guides ambient or hot air into the shoe body fixed to the support frame 20. In this way, the airflow generated by the single fan is evenly distributed to two independent ducts, ensuring that both shoes are simultaneously exposed to airflow. The design of the support frame 20 and the air guide nozzle 30 further ensures that the hot air is precisely applied to the shoe's interior space, improving drying efficiency. Therefore, this utility model achieves the function of drying two shoes simultaneously with a single fan, significantly improving efficiency. Secondly, it reduces the number of fans, lowering manufacturing costs and energy consumption, making the product more energy-efficient and environmentally friendly. Finally, its compact and reasonable structure and uniform airflow distribution avoid the uneven airflow problems that may occur with traditional dual-fan systems, thereby improving the uniformity and reliability of shoe drying.

[0038] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
