In addition, the heat shrink film is blown toward the outside of the shoe by hot air, so that some of the hot air will blow along the shoe surface into the trouser legs and onto the human skin, making people feel uncomfortable and affecting the user experience.

[0007] In view of this, the inventors propose the following technical solutions. Summary of the invention:

[0008] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a simple shoe cover machine with simple structure, simple manufacture and low cost.

[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions: the simple shoe cover machine includes: a container, which has a cavity for holding water; a heating element, which is arranged in the cavity of the container and is used to heat the water contained in the cavity; a support member that can generate elastic deformation, which is arranged in the cavity, and a support surface is formed on the upper end of the support member; a heat shrink film, which is attached to the support surface of the support member; when the shoe steps on the heat shrink film and presses downward against the support member, the pressed part of the support member sinks and deforms to form a pit for accommodating the shoe, and the inner wall of the pit will generate an outward-inward force on the edge of the heat shrink film to drive the edge of the heat shrink film toward the outside of the shoe, and the hot water entering the pit causes the edge of the heat shrink film to deform from the outside to the inside, so that the edge of the heat shrink film is tightly wrapped around the outside of the shoe to form a shoe cover.

[0010] Furthermore, in the above technical solution, the container is provided with a temperature sensor for detecting the temperature of the water in the cavity and a controller for controlling the operation of the heating element and cooperating with the temperature sensor to heat the water in the cavity to a constant temperature.

[0011] Furthermore, in the above technical solution, the controller and / or the heating element is connected to an isolated power supply, and the isolated power supply is connected to a wired plug.

[0012] Furthermore, in the above technical solution, the support member is a sponge.

[0013] Furthermore, in the above technical solution, the height of the sponge is smaller than the height of the cavity, and the height of the sponge is greater than the thickness of the sole of the shoe.

[0014] Furthermore, in the above technical solution, a limiting plate for limiting the support member is further provided in the container.

[0015] Furthermore, in the above technical solution, the heating element is any one or a combination of more than one of a heating silicone sheet, a heating pad, a heating wire, a heating plate, and a heating rod.

[0016] Furthermore, in the above technical solution, the heating element heats the water contained in the cavity to above 80°C and maintains the water temperature at at least 80°C.

[0017] Furthermore, in the above technical solution, the container includes a box body and a cover plate arranged at the upper end of the box body, the cover plate has a stepping hole for shoes to step into; the support member is exposed in the stepping hole.

[0018] Furthermore, in the above technical solution, the container is an open tray with an open opening at the upper end, and the support member is exposed in the open opening.

[0019] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the structure of the present invention is extremely simple and has fewer parts. It adopts a container with a water cavity, and places a heating element and a support element in the cavity, and its production cost is extremely low. When in use, the heat shrink film is manually attached to the support surface of the support element, and its operation is also relatively simple. When the shoe steps on the heat shrink film and presses downward on the support element, the shoe presses down on the support element, causing the support element to deform, wherein the pressed part of the support element sinks and deforms to form a pit to accommodate the shoe. At this time, After the hot water is added to the heating element, it will enter the pit. At the same time, the inner wall of the pit will generate an outside-to-inside force on the edge of the heat shrink film to drive the edge of the heat shrink film toward the outside of the shoe. The hot water entering the pit will deform the edge of the heat shrink film from the outside to the inside, so that the edge of the heat shrink film is tightly wrapped around the outside of the shoe to form a shoe cover. That is to say, the present invention deforms and shrinks the heat shrink film by contacting the heat shrink film with hot water, and there is no need to use a fan to blow out the heated air, so that the hot air will not be blown along the shoe surface to the trouser legs and onto the human skin, making people feel uncomfortable, thereby improving the user experience.

[0020] Figure 1 It is a structural diagram of the present invention;

[0021] Figure 2 This is a first usage state diagram of the present invention;

[0022] Figure 3 This is a second usage state diagram of the present invention. Specific implementation method:

[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0024] See Figure 1-3 As shown, a simple shoe cover machine includes: a container 1, a heating element 2, a support element 3 capable of generating elastic deformation, and a heat shrink film 4.

[0025] The heat shrinkable film 4 is a conventional product.

[0026] The container 1 has a cavity 11 for holding water; the heating element 2 is arranged in the cavity 11 of the container 1 and is used to heat the water contained in the cavity 11; the support member 3 is arranged in the cavity 11, and a support surface 31 is formed on the upper end of the support member 3; the heat shrink film 4 is attached to the support surface 31 of the support member 3; in specific use, when the shoe 5 steps on the heat shrink film 4 and presses downward toward the support member 3, the pressed part of the support member 3 sinks and deforms to form a pit 32 for accommodating the shoe, and the inner wall of the pit 32 will generate an outward-inward force on the edge of the heat shrink film 4 to drive the edge of the heat shrink film 4 toward the outside of the shoe 5, and the hot water entering the pit 32 causes the edge of the heat shrink film 4 to deform from the outside to the inside, so that the edge of the heat shrink film 4 is tightly wrapped around the outside of the shoe 5 to form a shoe cover.

[0027] The structure of the present invention is extremely simple and has few parts. It adopts a container 1 with a water-filled cavity 11, and places a heating element 2 and a support element 3 in the cavity 11, and its production cost is extremely low. When in use, the heat shrink film 4 is manually attached to the support surface 31 of the support element 3, and its operation is also relatively simple. When the shoe 5 steps on the heat shrink film 4 and presses downward on the support element 3, the shoe 5 presses down the support element 3, causing the support element 3 to deform, wherein the pressed part of the support element 3 sinks and deforms to form a pit 32 for accommodating the shoe. At this time, the hot water added by the heating element 2 will When the shoe 5 is in the shape of a shoe cover, the heat shrink film 4 is deformed from outside to inside by the hot water entering the concave 32, so that the edge of the heat shrink film 4 is tightly wrapped around the outside of the shoe 5 to form a shoe cover. In other words, the present invention deforms and shrinks the heat shrink film 4 by contacting the hot water with the heat shrink film 4, without the need for a fan to blow out the heated air, so that the hot air will not be blown along the shoe surface to the inside of the trouser legs and onto the human skin, causing people to feel uncomfortable, thereby improving the user experience.

[0028] It is worth mentioning that the size of the heat shrink film 4 is larger than the size of the sole, and even if the shoe 5 presses down the support member 3 and deforms the support member 3, the support member 3 is partially sunken and deformed to form a pit 32 for accommodating the shoe. After the edge of the heat shrink film 4 is tilted upward, the edge of the heat shrink film 4 is still higher than the upper end surface of the support member 3 or higher than the water surface, so that hot water will not directly contact the shoe. Even cloth shoes and other easily wet shoes can be used without getting the cloth shoes wet.

[0029] The container 1 is an open tray with an open opening 10 at its upper end, through which the support member 3 is exposed. The open tray can be made of metal, plastic, or other materials. The open tray has an extremely simple structure, is easy to manufacture, and is low-cost. In particular, a plastic tray can be integrally molded from plastic. The height or depth of the cavity 11 of the container 1 is greater than the thickness or height of the support member 3, ensuring that water within the cavity 11 does not overflow after the shoe 5 steps on the support member 3.

[0030] In order to enable the support member 3 to be more stably positioned in the cavity 11, the following design is also made: a limiting plate 16 for limiting the support member 3 is also provided in the container 1. The support member 3 is limited by the limiting plate 16, so that the support member 3 can be more stably positioned in the cavity 11, which is convenient for supporting the heat shrink film 4 in the later stage and enables the shoes to step on the support member 3 more accurately.

[0031] The limiting plate 16 is further provided with a plurality of transverse through holes 161 so that the support member 3 can better contact with water.

[0032] In other embodiments, the container 1 includes a box body and a cover plate disposed at the upper end of the box body, the cover plate having a stepping hole for shoes to step into; the support member 3 is exposed in the stepping hole. The container 1 of this structure is additionally provided with a cover plate, which has a certain water-blocking function and can better prevent water in the chamber 11 from overflowing. The cover plate only exposes the stepping hole for shoes to step into, so that the cover plate also prevents water from splashing out when shoes step on the support member 3. At the same time, the cover plate can also effectively prevent water from overflowing, making it more convenient to use.

[0033] In some embodiments, to ensure that the present invention is always in working order, that is, when the heat shrink film 4 is attached to the support surface 31 of the support member 3 and a shoe steps on the heat shrink film 4, pressing down the support member 3 and causing the support member 3 to deform, the recess 32 formed by the support member 3 enters hot water, which can directly contact the heat shrink film 4, thereby enabling the heat shrink film 4 to deform in a timely manner, the following configuration is made: the container 1 is provided with a temperature sensor 12 for detecting the temperature of the water in the chamber 11 and a controller 13 for controlling the operation of the heating element 2 and cooperating with the temperature sensor 12 to heat the water in the chamber 11 to a constant temperature. In other words, the temperature sensor 12 constantly detects the temperature of the water in the container 1. If the temperature is lower than a set temperature, the controller 13 controls the operation of the heating element 2 to heat the water in the chamber 11 to a constant temperature (e.g., above 80°C), thereby ensuring that the present invention is always in working order. Therefore, the heating element 2 heats the water in the chamber 11 to above 80°C and maintains the water temperature at at least 80°C.

[0034] The controller 13 and / or the heating element is connected to an isolated power supply 14, and the isolated power supply 14 is connected to a wired plug 15. The present invention adopts an isolated power supply 14 to connect the controller 13 and / or the heating element to control the heating element to realize heating work, which is safer to use. The isolated power supply isolates the input power supply from the output circuit through a transformer. There is no direct electrical connection between the primary coil and the secondary coil. It relies on magnetic coupling to realize energy transfer, which can prevent the risk of electric shock between the strong current and weak current systems. That is, the isolated power supply is highly safe and can prevent electric shock accidents, eliminate ground interference and the impact of lightning strikes. The isolated power supply is a prior art and will not be described in detail here.

[0035] The support member 3 is a sponge that can absorb water and produce elastic deformation, and has good supporting capacity. When the heat shrink film 4 is attached to the support surface 31 of the support member 3, the support member 3 has a certain degree of water absorption, which can stably adhere to and absorb the heat shrink film 4. Therefore, when the heat shrink film 4 is attached to the support surface 31 of the support member 3, the shoe is immediately stepped on the heat shrink film 4, thereby preventing the heat shrink film 4 from thermal shrinkage deformation after being attached to the support surface 31 of the support member 3.

[0036] The height of the sponge is smaller than the height of the cavity 11, and the height of the sponge is greater than the thickness of the sole of the shoe, so that when the sole of the shoe steps on the sponge, the depth of the pit 32 formed by the deformation of the sponge can be greater than or equal to the thickness of the sole, so that the edge of the heat shrinkable film 4 can better wrap around the sole of the shoe in the later stage, forming a more stable shoe cover.

[0037] The heating element 2 can be any one of a heating silicone sheet, a heating pad, a heating wire, a heating plate, or a heating rod, or a combination thereof. In this embodiment, the heating element 2 is a heating silicone sheet. In other embodiments, a heating pad, a heating wire, a heating plate, or a heating rod can be used. In other embodiments, a combination of a heating silicone sheet and a heating wire can achieve better water heating, resulting in faster and more uniform heating.

[0038] In summary, the structure of the present invention is extremely simple and has few parts. It adopts a container 1 with a water-filled cavity 11, and places a heating element 2 and a support element 3 in the cavity 11, and its production cost is extremely low. When in use, the heat shrink film 4 is manually attached to the support surface 31 of the support element 3, and its operation is also relatively simple. When the shoe 5 steps on the heat shrink film 4 and presses downward on the support element 3, the shoe 5 presses down the support element 3, causing the support element 3 to deform, wherein the pressed part of the support element 3 sinks and deforms to form a pit 32 for accommodating the shoe. At this time, the heat added by the heating element 2 Water will enter the pit 32. At the same time, the inner wall of the pit 32 will generate an outward-inward force on the edge of the heat shrink film 4 to drive the edge of the heat shrink film 4 toward the outside of the shoe 5. The hot water entering the pit 32 will deform the edge of the heat shrink film 4 from the outside to the inside, so that the edge of the heat shrink film 4 is tightly wrapped around the outside of the shoe 5 to form a shoe cover. That is to say, the present invention deforms and shrinks the heat shrink film 4 by contacting the heat shrink film 4 with hot water, without using a fan to blow out the heated air, so that the hot air will not be blown along the shoe surface to the trouser legs and onto the human skin, making people feel uncomfortable, thereby improving the user experience.

[0039] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made based on the structure, features and principles described in the scope of the patent application of the present invention should be included in the scope of the patent application of the present invention.
