DETAILED DESCRIPTION OF THE EMBODIMENTS

[0061] The present disclosure will be further described below in combination with the accompanying drawings and embodiments.

Embodiment 1

[0062] Referring to FIGS. 1-4, a telescopic shoe drying device comprises a body 10, a heater 20, and a fan 50. The heater 20 and the fan 50 are connected to the body 10. The body 10 comprises a base 11, a heat supply pipe 12, and a support 13. The heat supply pipe 12 is disposed on the base 11, and the support 13 is disposed on the heat supply pipe 12. Hot air generated by the heater 20 is transported out of the heat supply pipe 12 to heat an object to be dried by the fan 50. In some embodiments, the fan 50 is not provided, and the hot air generated by the heater 20 heats the object to be dried through natural convection.

[0063] The heat supply pipe 12 comprises an inner pipe 121 disposed on the base 11, an outer pipe 122 encompassing an outer side of the inner pipe 121 and configured to move up and down (i.e., in a vertical direction), and a locking mechanism. The locking mechanism comprises two locking bases 123 (i.e., at least two slide bases) and two elastic bodies 124. The two locking bases 123 are connected to the inner pipe 121 and are configured to move in and out, and the two locking bases 123 are configured to move between an extended position and a retracted position relative to the inner pipe 121. For example, when the two locking bases 123 move in and out, the two locking bases 123 may be brought close to each other or separated from each other, or the two locking bases 123 may move horizontally close to or away from to an axial central line of the inner pipe 121. The two elastic bodies 124 are connected to the two locking bases 123 to generate elastic force to enable the two locking base 123 to move outward. When the two locking bases 123 are in the extended position, the locking mechanism is in a locked state, and the outer pipe 122 abuts the two locking bases 123. When two the locking bases 123 are in the retracted position, the locking mechanism is in an unlocked state, and the outer pipe 122 can move up and down relative to the inner pipe 121. Cross-sections of the inner pipe 121 and the outer pipe 122 define frame-like rectangular structures.

[0064] In this embodiment, the two locking bases 123 each comprises a connecting base 120 and an outer convex base 125 (i.e., a protruding portion) secured to an outer wall of the connecting base 120. When the two locking bases 123 are in the extended position, the locking mechanism is in the locked state, and a bottom end surface of the outer pipe 122 abuts the outer convex bases 125. Referring to FIG. 1, at this time, the heat supply pipe 12 is maintained in the extended state. In some embodiments, the outer pipe 122 can also be disposed with multiple through hole groups disposed up and down at intervals, and the outer convex bases 125 cooperate and are disposed in the multiple through hole groups to enable the outer pipe 122 to abut the two locking bases 123 and to achieve multi-stage adjustment of a telescopic length. Moreover, when the two locking bases 123 are pressed to enable the two locking bases 123 to be in the retracted position, the locking mechanism is in the unlocked state, and the outer pipe 122 is configured to move up and down relative to the inner pipe 121. Referring to FIG. 2, when the outer pipe 122 abuts the base 11, the two locking bases 123 are each disposed in the outer pipe 122, and the heat supply pipe 12 is in a retracted state.

[0065] In this implementation, an outer peripheral surface of an upper portion of the inner pipe 121 is concave to define an annular groove 126 (i.e., a sliding groove). The connecting bases 120 each defines a C-shaped structure and comprises two end portions. The connecting bases 120 cooperate and are slidably disposed in the annular groove 126. In some embodiments, the annular groove 126 comprises two groove walls 1261 separated up and down, at least one groove wall of the two groove walls 1261 comprises a sliding groove 127, the connecting bases 120 comprise sliding rails 128, and the sliding rails 128 cooperate and are connected to the sliding groove 127. The two elastic bodies 124 are each disposed in the annular groove 126, and the two elastic bodies 124 abut and are disposed between the end portions of the C-shaped structures of the two connecting bases 120. At least one groove wall of the two groove walls 1261 comprises a matching groove 1262, and the connecting bases 120 comprise anti-separation protrusions 129. The anti-separation protrusions 129 are defined on cantilever arms 1201. The cantilever arms 1201 are defined on the connecting bases 120, and the anti-separation protrusions 129 are disposed in the matching groove 1262. The annular groove 126 and the two locking bases 123 define a connecting mechanism 100.

[0066] In this embodiment, the heater 20 comprises a heating component 143 and a heat conducting component 140. The heat conducting component 140 is secured on the base 11, and the inner pipe 121 encompasses an outer side of the heat conducting component. The heating component 143 is disposed on a mounting portion 142, and the mounting portion 142 is disposed in the base 11. The heat conducting component 140 comprises, for example, a heat dissipation pipe 141.

Embodiment 2

[0067] Referring to FIG. 5, this embodiment differs from Embodiment 1 in that the cross-sections of the inner pipe 121 and the outer pipe 122 of Embodiment 1 have frame-like rectangular structures. The cross-sections of the inner pipe 121 and the outer pipe 122 of this embodiment are both circular.

Embodiment 3

[0068] Referring to FIGS. 6-15, a telescopic shoe drying device comprises a body 10 and a heater 20. The body 10 comprises a base 11 and a heat supply pipe 12. The heat supply pipe 12 is disposed on the base 11, and the heater 20 is disposed on the body 10. Hot air generated by the heater 20 is transported out of the heat supply pipe 12. The heat supply pipe 12 comprises three pipes encompassing each other and configured to slide relative to each other. The three pipes define a multi-section telescopic mechanism. The three pipes respectively define a lower pipe 121′, a middle pipe 122′, and an upper pipe 123′. The lower pipe 121′ is disposed on the base 11, the middle pipe 122′ is slidably connected to the lower pipe 121′, and the upper pipe 123′ is slidably connected to the middle pipe 122′. In this embodiment, the lower pipe 121′ is swingably connected to the base 11 to enable the heat supply pipe 12 to be folded or unfolded relative to the base 11. When in a folded state, the structure of the telescopic shoe drying device is compact, occupies a small amount of space, and is convenient for packaging, transportation, and storage. However, the structure of the telescopic shoe drying device is not limited thereto. For example, the lower pipe 121′ can be fixedly connected to the base 11.

[0069] The middle pipe 122′ is configured to be slidably disposed in the lower pipe 121′. The middle pipe 122′ comprises a first protrusion 1221 configured to move between a convex state and a non-convex state relative to the middle pipe 122′. When the first protrusion 1221 is in the convex state, the first protrusion 1221 abuts an end surface of the lower pipe 121′ to enable the middle pipe 122′ and the lower pipe 121′ to be maintained in an extended state. Therefore, extension and retraction of the middle pipe 122′ relative to the lower pipe 121′ are convenient and support stability is high. In some embodiments, the middle pipe 122′ is connected to the first protrusion 1221 through a first cantilever 1222 configured to be elastically deformed relative to the middle pipe 122′. Further, the middle pipe 122′ comprises a first through hole 1223 penetrating an inner side and an outer side of the middle pipe 122′. The first cantilever 1222 is disposed in the first through hole 1223, and an end of the first cantilever 1222 is secured to an inner wall of the first through hole 1223. The structure is therefore simple and compact, pressing of the first protrusion 1221 is convenient, the extending and retracting are convenient, and the production cost is low. In order to facilitate the pressing, a first pressing portion 1224 is disposed on the first cantilever 1222. The first pressing portion 1224 is disposed above the first protrusion 1221, and the first pressing portion 1224 is separated from the first protrusion 1221. When the lower pipe 121′ and the middle pipe 122′ are maintained in the extended state, the first pressing portion 1224 is disposed out of the lower pipe 121′ and the pressing is convenient for the user, thereby enabling the user to easily release support and be retracted.

[0070] The middle pipe 122′ protrudes to define a first anti-separation protrusion 1225, and an inner wall of the lower pipe 121′ is disposed with a first shielding portion 1212. The first anti-separation protrusion 1225 cooperates with the first shielding portion 1212 to prevent separation from the lower pipe 121′ (i.e., prevent the middle pipe 122′ from being separated from the lower pipe 121′), and the structure is simple and reliable. In some embodiments, when the first protrusion 1221 abuts the end surface of the lower pipe 121′, the first anti-separation protrusion 1225 abuts the first shielding portion 1212, so that the first anti-separation protrusion 1225 can not only prevent separation but also enable the multi-section telescopic mechanism to be stable and reliable due to a cooperation of this structure.

[0071] The upper pipe 123′ is disposed with a connecting pipe 1230 and an insertion pipe 1231 secured to the connecting pipe 1230. The insertion pipe 1231 cooperates and is disposed in the middle pipe 122′, and the insertion pipe 1231 and the middle pipe 122′ define a telescopic sliding connection. The insertion pipe 1231 comprises a second protrusion 1232 configured to move between a convex state and a non-convex state relative to the insertion pipe 1231. When the second protrusion 1232 is in the convex state, the second protrusion 1232 abuts an end surface of the middle pipe 122′ to enable the insertion pipe 1231 and the middle pipe 122′ to be maintained in the extended state. In some embodiments, the insertion pipe 1231 is connected to the second protrusion 1232 through a second cantilever 1233 configured to be elastically deformed relative to the insertion pipe 1231. Further, the insertion pipe 1231 comprises a second through hole 1234 penetrating an inner side and an outer side of the insertion pipe 1231. The second cantilever 1233 is disposed in the second through hole 1234, and an end of the second cantilever 1233 is secured to an inner wall of the second through hole 1234. An outer wall of the connecting pipe 1230 is aligned with an outer wall of the lower pipe 121′. In order to facilitate pressing by a user, a second pressing portion 1238 is disposed on the second cantilever 1233. The second pressing portion 1238 is disposed above the second protrusion 1232, and the second pressing portion 1238 is separated from the second protrusion 1232. When the upper pipe 123′ and the middle pipe 122′ are maintained in the extended state, the second pressing portion 1238 is disposed out of the middle pipe 122′, and the pressing is convenient for the user, thereby enabling the user to easily release support and be retracted.

[0072] The insertion pipe 1231 protrudes to define a second anti-separation protrusion 1236 (i.e., an insertion member) configured to move between a convex state and a non-convex state relative to the insertion pipe 1231, and the middle pipe 122′ comprises a matching groove 1262 (i.e., an insertion groove). The insertion member and the insertion groove define an anti-separation structure 12300. When the second anti-separation protrusion 1236 is in the convex state, the second anti-separation protrusion 1236 is disposed in the matching groove 1262 to prevent separation from the middle pipe 122′. The middle pipe 122′ comprises a fourth through hole 1226 penetrating an inner side and an outer side of the middle pipe 122′, and a fourth cantilever 1227 is disposed in the fourth through hole 1226. An end of the fourth cantilever 1227 is connected to an inner wall of the fourth through hole 1226. The fourth cantilever 1227 cooperates with the second anti-separation protrusion 1236, and the fourth cantilever 1227 abuts the second anti-separation protrusion 1236 to enable the second anti-separation protrusion 1236 to move to the non-convex state. In some embodiments, the inner wall of the fourth cantilever 1227 can comprise the matching groove 1262. An outer wall of the fourth cantilever 1227 is disposed with a pressing head 1229. An operation of the structure is convenient, and the structure is simple and compact.

[0073] In this embodiment, the insertion pipe 1231 comprises a third protrusion 1235 configured to move between a convex state and a non-convex state relative to the insertion pipe 1231, and the middle pipe 122′ comprises a third through hole 1220. When the third protrusion 1235 is in the convex state, the third protrusion 1235 is disposed in the third through hole 1220 to enable the multi-section telescopic mechanism to be maintained in the retracted state due to a cooperation of the third protrusion 1235 and the third through hole 1220. A structure of the third protrusion 1235 of the insertion pipe 1231 is similar to a structure of the second protrusion 1232 of the insertion pipe 1231. The insertion pipe 1231 is connected to the third protrusion 1235 through a third cantilever 12351 configured to be elastically deformed relative to the insertion pipe 1231.

[0074] The base 11 comprises an upper shell 111 and a lower shell 112, and the upper shell 111 is secured to the lower shell 112. The heater 20 is disposed between the upper shell 111 and the lower shell 112. The heater 20 is disposed with a metal heat conduction device 1210 (i.e., a metal heat conduction sheet), the heater 20 and the metal heat conduction device 1210 are secured in the lower pipe 121′. Heat generated by the metal heat conduction device 1210 of the heater 20 blows out of the heat supply pipe 12. In some embodiments, the telescopic shoe drying device can comprise a fan 50. For example, the fan 50 is disposed in the base 11 or the lower pipe 121′. The fan 50 and the heater 20 cooperate to generate hot air. The hot air blows out of a nozzle of the heat supply pipe 12 to transfer heat.

[0075] The insertion pipe 1231 is further concave to define a give-way groove 1237 configured to cooperate with the first cantilever 1222 and to be pressed by the first pressing portion 1224. The give-way groove 1237 ensures that the multi-section telescopic mechanism is orderly retracted. For example, the upper pipe 123′ and the middle pipe 122′ are firstly retracted, and then the combination of the upper pipe 123′ and the middle pipe 122′ cooperates with the lower pipe 121′ to be retracted.

[0076] The connecting pipe 1230 comprises a first body 12301 integrated with the insertion pipe 1231 and a first fitting body 1239 configured to be secured to the first body 12301 by screws. The lower pipe 121′ comprises a second body 12110 and a second fitting body 1211 configured to be secured on the second body 12110.

[0077] In some embodiments, the end of the upper pipe 123′ is disposed with the support 13. The support 13 and the heat supply pipe 12 define a detachable connection structure. The telescopic shoe drying device can adapt to support a variety of supports. For example, the support 13 can be a five-finger support configured to be encompassed by gloves, or a shoe support for supporting shoes, or a ball-shaped support for supporting a helmet. The support 13 is convenient to be replaced by the detachable connection structure.

[0078] In some embodiments, a connection between the upper pipe 123′ and the middle pipe 122′ and a connection between the middle pipe 122′ and the lower pipe 121′ can be formed by the locking mechanism disclosed in Embodiments 1 and 2. In some embodiments, the multi-section telescopic mechanism can comprise four pipes or five pipes.

[0079] The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure of is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations (i.e., non-substantial variations) of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
