Description

Technical Field

[0001] The invention relates to the field of household appliances, and in particular to a retractable and adjustable shoe support and a supporting method of a shoe dryer and the shoe dryer. Background Art

[0002] Shoe dryers, also known as shoe dryers and shoe warmers, are small appliances designed specifically for drying shoes. Shoe dryers have the functions of drying, sterilizing, and deodorizing, so they can help people solve some foot-related troubles and problems, such as cold feet, athlete's foot, and frostbite, and can greatly meet people's needs for solving daily foot troubles.

[0003] The shoe dryer is suitable for various cotton shoes, cloth shoes, leather shoes, travel shoes, washed shoes, leaking shoes, long boots and other shoes. On the existing market, there is a shoe dryer with a telescopic function with a patent number of 2018222733501 and a publication number of CN20980824U. The patent records the following technical scheme: the shoe dryer includes a main body and a heater. The main body includes a base and a heat pipe. The heat pipe is mounted on the base. The heater is mounted on the main body and the hot air generated by the heater is output from the heat pipe. The heat pipe includes at least three sections of inner and outer pipes that are connected and can slide relative to each other. The at least three sections of pipes constitute a multi-section telescopic mechanism. The heat pipe includes three sections of pipes, which are a lower pipe, a middle pipe and an upper pipe respectively. The lower pipe is mounted on the base. The middle pipe can be slidably connected to the lower pipe, and the upper pipe can be slidably connected to the middle pipe.

[0004] During use of the shoe dryer recorded in the above technical solution, since the three sections of the pipes are only used to change the length of the heat transfer pipe along the expansion and contraction direction of the pipes, the shoe dryer of this structure has the following defects: first, when the shoe dryer is used to dry shoes such as long boots, the top of the heat transfer pipe is located in front of the sole of the long boot, and the upper of the long boot will hang along the outer wall of the heat transfer pipe. At this time, since the fixed angle of the boot is basically consistent with the length direction of the heat transfer pipe, the part of the upper of the long boot close to the tube mouth will wrap the outer wall of the heat transfer pipe, resulting in a relatively closed space. As the heating time increases, the boots and the heat transfer pipe cannot be refluxed with the outside world, which will cause the heat transfer pipe to deform or cause the long boots to be overheated and damaged; second, when the shoe dryer is used to dry various types of shoes, the top of the heat transfer pipe is located in front of the sole of the long boot, and the heat is concentrated from this point and then released to other spaces in the shoe, resulting in extremely uneven heating, thereby reducing the drying efficiency. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a retractable and adjustable shoe support and a supporting method for a shoe dryer, and a shoe dryer thereof, which can expand the shoe opening angle and improve the drying efficiency.

[0006] On one hand, the present invention provides a retractable and adjustable shoe tree for a shoe drying machine, comprising a plurality of retractable heat transfer tubes, the top end of the heat transfer tube being rotatably connected to a bearing part, the bearing part being hollow, the hollow part forming a heat transfer cavity, the heat transfer cavity being communicated with the heat transfer tube, and a conduction hole being communicated with the conduction cavity being arranged on the surface of the bearing part, a gear adjustment device being arranged between the bearing part and the heat transfer tube, and the angle of the bearing part relative to the heat transfer tube being controlled by the gear adjustment device.

After the shoes are installed on the load-bearing part, the angle between the load-bearing part and the heat transfer tube will not change with the weight of the shoes, thereby ensuring the stability of the shoe dryer during operation and further ensuring safety.

[0012] The present invention is further configured as follows: the first guide arc plate and the end of the heat transfer tube facing the bearing portion form an inwardly concave step, and the step is used for limiting the position when the bearing portion rotates back to the length direction of the heat transfer tube.

[0013] By adopting the above technical solution, when the bearing part rotates around the rotating connection to be consistent with the length direction of the heat transfer tube, the corresponding part of the bearing part can be connected to the corresponding step, thereby realizing a fixed connection between the bearing part and the heat transfer tube, ensuring the stability of the most original structure used in the shoe stretcher, and realizing the positioning function at various angles between the bearing part and the heat transfer tube.

[0014] The present invention is further configured as follows: a groove is arranged on the side of the heat transfer tube facing the bearing part, and a rotating protrusion matched with the groove is arranged on the bearing part, and the rotating protrusion is rotatably connected to the groove.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figure 1 — Figure 4 As shown, the present invention provides a retractable and adjustable shoe tree for a shoe drying machine, comprising a plurality of retractable heat transfer tubes 1, the top of the heat transfer tube 1 being rotatably connected to a bearing part 2, the bearing part 2 being hollow, the hollow part forming a heat transfer cavity 21, the transfer cavity 21 being communicated with the heat transfer tube 1, and a transfer hole 22 being communicated with the transfer cavity is provided on the surface of the bearing part 2, a gear adjustment device is provided between the bearing part 2 and the heat transfer tube 1, the gear adjustment device is used to control the angle of the bearing part relative to the heat transfer tube, and the shoe tree with an adjustable angle of the bearing part can effectively fix the shoes to be dried at a certain position. When the shoe tree is put on, the shoe mouth is opened, and no matter whether it is a long boot or any other type of shoes except long boots, the shoe upper and the shoe sole are opened at the maximum angle on the shoe tree, so that the upper of the long boot is prevented from being attached to the outer wall of the heat transfer tube, and the situation of damaging the heat transfer tube and the shoes is effectively solved; the upper surface of the bearing part can be effectively connected with the sole of the shoe to be dried, so that the heat transfer area of ​​the bearing part is expanded, and the surface of the bearing part is provided with conduction holes, so that the heat can be dried from multiple angles to dry the shoes to be dried, which greatly improves the drying efficiency and achieves the effect of energy saving and environmental protection.

[0036] like Figure 6-8 As shown, the angle between the bearing part and the heat transfer tube is adjusted according to different conditions of the shoes, such as Figure 6 As shown in , the upper surface of the bearing part is almost flush with the plane of the sole, and the angle between the outer wall of the heat transfer tube and the upper surface of the bearing part is between 90-110 degrees, close to 90 degrees. At this time, when the shoes are fixed on the bearing part, the upper part of various shoes has the largest opening. Especially for drying long boots, this angle can open the opening of the upper to the maximum extent to avoid the upper fitting. If the upper is long, the outermost side of the upper can be bent inward to avoid the upper being too long and covering the shoe dryer. Figure 7 As shown in , the angle between the outer wall of the heat transfer tube and the upper surface of the bearing portion is between 130-140 degrees. At this time, when the shoes are fixed on the bearing portion, the upper part of various shoes has a larger opening; Figure 8 As shown, the angle formed by the outer wall of the heat transfer tube and the upper surface of the bearing portion is close to 180 degrees. At this time, when the shoes are fixed on the bearing portion, the opening of the upper part of each type of shoe is the smallest.

The guide device 3 includes a first guide arc plate 31 extending toward the bearing part from the end of the heat transfer tube toward the bearing part. A second guide arc plate 32 adapted to the first guide arc plate is provided on the bearing part. When the bearing part is adjusted at an angle to the heat transfer tube, in order to facilitate the rotation of the bearing part, the bearing part is ensured to rotate smoothly during the rotation process, and smooth adjustment can be achieved regardless of whether the shoe is installed on the bearing part before or after the shoe is installed on the bearing part.

[0038] In a specific embodiment of the present invention, the gear adjustment device includes three positioning grooves 5 arranged on the outer wall of the heat transfer tube, and a positioning protrusion (not shown in the figure) is arranged on the inner side of the bearing part. The three positioning grooves 5 are all located on the movement path of the positioning protrusion. As long as the bearing part rotates, the three gears of the bearing part can be adjusted to three angles to fix the shoes at different angles. Of course, multiple gears including but not limited to 2 gears, 4 gears and 5 gears can be set according to needs, which can be designed with the same structure.

[0039] By adopting the above technical solution, the fixed connection between the load-bearing part and the heat transfer tube is facilitated. After the shoes are installed on the load-bearing part, the angle between the load-bearing part and the heat transfer tube will not change with the weight of the shoes, thereby ensuring the stability of the shoe dryer during operation and further ensuring safety.

[0040] In a specific embodiment of the present invention, the first guide arc plate 31 and the end of the heat transfer tube facing the bearing portion form a concave step 6, which is used for limiting the position when the bearing portion 2 rotates back to the length direction of the heat transfer tube 1.

[0041] By adopting the above technical solution, when the bearing part rotates around the rotating connection to be consistent with the length direction of the heat transfer tube, the corresponding part 7 of the bearing part can be connected to the step 6 accordingly, thereby realizing a fixed connection between the bearing part and the heat transfer tube, ensuring the stability of the most original structure used in the shoe stretcher, and realizing the positioning function at various angles between the bearing part and the heat transfer tube.

[0042] In a specific embodiment of the present invention, a groove 5 is provided on the side of the heat transfer tube 1 facing the bearing portion, and a rotating protrusion (not shown) matching the groove 5 is provided on the bearing portion, and the rotating protrusion is rotatably connected to the groove.

[0043] By adopting the above technical solution, the structure has strong stability, low cost and is easy to implement.

[0044] Example 2

[0045] The other structures are the same. In the gear shifting device, the positioning groove and the positioning protrusion are interchanged in position, that is, the positioning protrusion is arranged on the outer wall of the heat transfer tube, and several positioning grooves are arranged on the bearing part, and several positioning grooves are all located on the movement path of the positioning protrusion.
