[0038] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0039] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships described in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] See also Figure 1-10 As shown, one embodiment of the utility model provides a rollable bathtub cover, which includes a protective layer 1, a support layer 2, a thermal insulation layer 4 and a sealing layer 5 in sequence, wherein the support layer 2 is installed on one side of the thermal insulation layer 4, the sealing layer 5 is arranged on the other side of the thermal insulation layer 4, the sealing layer 5 is arranged at the edge of the thermal insulation layer 4, and the sealing layer 5 is arranged on at least two sides of the thermal insulation layer 4.

[0041] The utility model discloses a rollable bathtub cover, which protects the support layer 2, the insulation layer 4 and the sealing layer 5 through the protective layer 1, so as to prevent rainwater, snow or dust from entering the support layer 2 and the insulation layer 4, thereby reducing the overall service life. The support layer 2 is used to support the entire bathtub cover. When the device is placed on the bathtub as a whole, if there is no support layer 2, when it rains or snows outdoors, when rainwater or snow accumulates on the protective layer 1, the insulation layer 4 will collapse in the middle, making it impossible to insulate the outdoor hot spring or bathtub. When the bathtub cover is placed on the outdoor hot spring or bathtub, a gap will appear on the edge, or when it contacts the ground, a gap will appear, which will cause the hot air in the bathtub to overflow, causing heat loss, so that the insulation effect of the bathtub cover cannot reach the best. The present structure adds a sealing layer 5, which is attached to the edge of the bathtub after being subjected to the self-weight pressure of the bathtub cover, so as to fill the gap and prevent the hot air from overflowing, thereby improving the insulation effect.

[0042] In one embodiment, the sealing layer 5 is a sealing insulation strip 501, and the sealing insulation strip 501 includes an outer layer 501 and a filling layer 502. The outer layer 501 is provided with a cavity, and the cavity is filled with the filling layer 502, and the filling layer 502 is made of a soft insulation material. The soft insulation material is one or more of aluminum foil, space cotton, pearl cotton, and XPE material. In this embodiment, space cotton is used for filling. The soft insulation material in the utility model should not be limited to the materials listed above. As long as the material can achieve the insulation effect, it should fall into the protection scope of the utility model.

[0043] In one of the embodiments, the thermal insulation layer 4 and the sealing layer 5 are integrally formed to form a thermal insulation sealing layer 5, and the thermal insulation sealing layer 5 is flat in the middle and has strip-shaped protrusions on both sides; the difference from the previous embodiment is that the previous embodiment uses a sealing insulation strip 501 arranged on the outside of the thermal insulation layer 4 to achieve the effect of sealing the edge gap. In this embodiment, the thermal insulation layer 4 and the sealing layer 5 are integrally formed, so that the thermal insulation layer 4 forms a thermal insulation seal. The thermal insulation sealing layer 5 is flat in the middle and has strip-shaped protrusions on both sides, and an outer layer is wrapped on the outside to form the thermal insulation sealing layer 5.

[0044] Specifically, the bathtub cover of the utility model is a rollable bathtub cover. As the bathtub cover is continuously rolled up and unfolded, the bathtub cover will be uneven, especially the edge, which will produce uneven gaps. When in use, the bathtub cover is flattened by its own weight, but there will still be gaps, causing the heat to escape and lose. In the utility model, the above-mentioned disadvantages are overcome by adding a sealing layer 5 at the edge; the sealing layer 5 can make the bathtub cover better fit the edge of the bathtub or the ground after being pressed down, thereby greatly reducing the gap between the bathtub cover and the ground, and the filling layer 502 can be made of soft insulation material. The sealing layer 5 is provided with at least two, which are provided at the edge perpendicular to the keel of the bathtub cover.

[0045] In one embodiment, the support layer 2 is provided with an arched structure 204, and the arched structure 204 is a solid structure. The arched surface of the arched structure 204 is connected to the protective layer 1, and is used to push the protective layer 1 outward to form an arc surface; the conventional support layer 2 is provided with a mechanism for pushing outward generally adopts a bar bending support, and this support method is easy to cause the protective layer 1 to deform during use, and in the case of accumulated rain and snow, it may even collapse due to excessive force, and the supporting effect is not good; the solid arched structure 204 is used in this embodiment, which will not cause the above problems and has an excellent supporting effect. When the arched structure 204 is made of metal material or other hard materials, a keel is not required, and it directly plays the role of lifting the protective layer 1 and supporting the entire bathtub cover; the arched structure 204 can also be made of, but not limited to, plastic, sponge, wood and other materials, and other materials should also fall within the protection scope of the present utility model.

[0046] In one embodiment, a fastening clip 301 is further provided at the upper end of the arch surface of the arch structure 204, and the fastening clip 301 is made of metal material. In this embodiment, it is made of aluminum material. The fastening clip 301 is an arch structure, which is tightly clamped on the arch surface of the arch structure 204. The upper end of the fastening clip 301 is fixed with a ridge belt 3 through a second fixing member 208. In this embodiment, the second fixing member 208 is a screw. The ridge belt 3 is used to connect all the laid arch structures 204. When the bathtub cover is spread out, the arch structure 204 may fall due to external force. At this time, it is necessary to pull the ridge belt 3 to reset the arch structure 204. The traditional structure is to directly drive the ridge belt 3 into the arch structure 204 through screws. 4, since the length of the spine belt 3 is fixed during production, during the installation step, when the screws are directly driven in, the screws will be sunk too deep into the arch structure 204, thereby pulling the spine belt 3 in, and the connection length of the spine belt 3 becomes shorter due to manual operation, which causes the arch structure 204 to be forced to be pulled and cannot be fully erected; and during use, when the spine belt 3 is pulled to reset the arch structure 204, since only the screws and the arch structure 204 generate contact force, repeated use will expand the screw holes on the arch structure 204, thereby causing the screws to fall off and lose their function. In this embodiment, a fastening clamp 301 is provided. When the spinal belt 3 is fixed, the screw penetrates the spinal belt 3, is driven into the surface of the fastening clamp 301, and then is nailed into the arch structure 204. Firstly, since the fastening clamp 301 is made of metal material, the spinal belt 3 is prevented from sinking into the arch structure 204 due to the force of the screw, and the spinal belt 3 will not be shortened in usable length; secondly, the screw is connected to the fastening clamp 301, and when repeatedly pulled, it is not easy to expand the screw hole on the fastening clamp 301, thereby enhancing the fixing effect; finally, since the fastening clamp 301 is clamped on the arch structure 204, the fastening clamp 301 in the embodiment here is arched. When the spinal belt 3 is pulled, both ends of the fastening clamp 301 simultaneously act on the arch structure 204 to reset it, thereby increasing the force-bearing area, reducing the force between the screw and the arch structure 204, and making the screw not easy to fall off.

[0047] In one embodiment, the support layer 2 includes a plurality of keels 201, which are laid on the insulation layer 4 in a regular array, and the keels 201 are provided with a hollow tubular structure 202, wherein the hollow tubular structure 202 may be a geometric hollow tubular structure 202, not limited to square, rectangular, circular, rhombus, polygonal, etc. The hollow tubular structure 202 is made of plastic material by injection molding, and is provided with openings, and the insulation layer 4 and the arch structure 204 are fixed by fixing parts; during the process of rolling and unfolding the bathtub cover, the insulation layer 4 and the arch structure 204 will be subjected to external force or friction of components, causing friction between the fixing parts and the openings on the hollow tubular structure 202, and since the bathtub cover is made of plastic material, the openings are enlarged by bolts or fixing parts during multiple movements, and when the openings gradually become larger, the fixing parts are easily fallen off, thereby loosening the parts, damaging the structure of the bathtub cover, and shortening the service life of the bathtub cover.

[0048] In order to overcome the above-mentioned defects, in one embodiment, a metal layer 203 is provided, and the metal layer 203 is sleeved inside the hollow tubular structure 202 . The metal layer 203 matches and fits the shape of the hollow tubular structure 202; in this embodiment, the metal layer 203 is made of aluminum material, and the metal layer 203 can also be made of other metal materials such as stainless steel, iron, etc., and other metal materials should also fall into the protection scope of the utility model; after the metal layer 203 is added, the fixing piece is punched into the metal layer 203 through the round hole, which can solve the problem that the opening on the hollow tubular structure 202 is enlarged by the bolt or the fixing piece during multiple movements. Even under the action of external force, the fixing piece is not easy to fall off from the metal layer 203, thereby improving the fixing effect and enhancing the stability and service life of the bathtub cover; and the addition of the metal layer 203 to the keel 201 also increases the bearing capacity of the keel 201, so that the bearing capacity of the bathtub cover is enhanced; and in this embodiment, the metal layer 203 is made of aluminum material, and the aluminum keel 201 is not only light in material, but also has better toughness and is not easy to break, and will not significantly increase the weight of the bathtub cover.

[0049] Furthermore, the device as a whole can be rolled into a cylindrical shape when not in use, so as to facilitate storage. The above-mentioned keels 201 are laid on the insulation layer 4 in a regular array, and are laid in a horizontal array, and there is a certain distance between every two keels 201, so that there will be no conflict when rolling up. The spacing of the keels 201 is 28~35cm. When the spacing of the keels 201 is less than 28cm, the number of fixings on the insulation layer 4 will increase, which increases the cost and is not beautiful. In addition, if too many keels 201 are laid, the weight of the bathtub cover will be too large, which is not conducive to rolling up and using; when the spacing of the keels 201 is greater than 35cm, the supporting force of the supporting structure will be weakened. When in use, the weight of external snow or rainwater will easily cause the bathtub cover to collapse.

[0050] In one embodiment, the laying interval of the keels 201 is 30 cm. It should be noted that even if the laying interval of the keels 201 is other intervals, it should also fall within the protection scope of the present utility model.

[0051] In one of the embodiments, the keel 201 is further provided with a bow structure 204, and a plurality of first fixing members 207 are arranged on the bow structure 204. The bow structure 204 is fixed to the surface of the keel 201 away from the thermal insulation layer 4 by the plurality of first fixing members 207. The first fixing members 207 sequentially penetrate the bow structure 204, the hollow tubular structure 202 and the metal layer 203 and extend into the metal layer 203, so that the bow block is fixedly connected to the keel 201.

[0052] Specifically, the arch structure 204 is used to support the protective layer 1 , and the arch structure 204 is fixed to the hollow tubular structure 202 and the metal layer 203 by a first fixing member 207 .

[0053] It should be noted that the height of the edge of the arched structure 204 is lower than the height of the center position after supporting the protective layer 1, so that when it rains or snows, rain and snow will not remain too much on the protective layer 1, and the overall load-bearing capacity is further improved through the arched structure 204. Because the widths of the various positions of the arched structure 204 are inconsistent, the first fixing assembly used needs to be adapted according to the width of the arched structure 204, and the first fixing member 207 needs to be driven into the metal layer 203 or threaded into the metal layer 203. In this embodiment, the arched structure 204 is made of elastic material, not limited to one material.

[0054] In one embodiment, the arch structure 204 includes a left arc block 205 and a right arc block 206, and the left arc block 205 and the right arc block 206 are symmetrically arranged on the hollow tubular structure 202. In this embodiment, the arch structure 204 is divided into two pieces, which plays a supporting role and is easy to open molds, produce, transport and assemble during the production process.

[0055] In this embodiment, a fastening clip 301 is provided, and the fastening clip 301 is located at the connection between the left arc block 205 and the right arc block 206. While being connected to the spinal belt 3, the fastening clip 301 can also fix the left arc block 205 and the right arc block 206 to form an integral arch structure 204.

[0056] In one embodiment, both ends of the keel 201 are also sleeved with a trapezoidal seat 6, the bottom surface of the trapezoidal seat 6 is connected to the thermal insulation layer 4, the trapezoidal seat 6 is provided with a mounting groove 601 adapted to the shape of the port of the keel 201, and an air-insulating layer 602 is provided on both sides of the trapezoidal seat 6. The provided mounting groove 601 allows the trapezoidal seat 6 to be sleeved on both ends of the keel 201 without the need for external fixings; and the provided air-insulating layer 602 has a support bar 603 and a cavity, and the support bar 603 can play a supporting role when the bathtub cover is opened; when the cavity is rolled up, no additional resistance will be generated, which increases the difficulty of rolling up.

[0057] Specifically, the bottom area of ​​the trapezoidal seat 6 is relatively large, so that after the insulation layer 4 and the sealing layer 5 are pressed down, the downward pressure can be more uniform, so that the sealing layer 5 can better reduce the generation of gaps after contacting the ground, thereby improving the insulation effect.

[0058] It should be noted that the trapezoidal seat 6 is also a soft structure. When rolling up, the two sides of the trapezoidal seat 6 will be squeezed and folded in half, thereby facilitating the rolling up of the device. The installation groove 601 facilitates the installation of the trapezoidal seat 6.

[0059] In one embodiment, the insulation layer 4 is provided with a plurality of third fixing members 7, and the insulation layer 4 is fixed to the keel 201 by the plurality of third fixing members 7. The insulation layer 4 is provided with an inner liner 401, and the inner liner 401 is filled with a soft insulation material, and the soft insulation material is one or more of aluminum foil, space cotton, pearl cotton, and XPE material. In this embodiment, the inner liner 401 is filled with aluminum foil. Aluminum foil is used as the insulation layer 4. First, the aluminum foil has a liquid-isolating effect, which makes the insulation time longer. The aluminum foil itself is light and has good insulation performance, which can reduce the weight of the bathtub cover. The soft insulation material in the utility model should not be limited to the materials listed above. As long as the material can achieve the insulation effect, it should fall into the protection scope of the utility model.

[0060] The third fixing member 7 is provided with a first barb portion 701 and a second barb portion 702, wherein the first barb portion 701 is located above the second barb portion 702, the cross-sectional area of ​​the first barb portion 701 is greater than the cross-sectional area of ​​the second barb portion 702, the first barb portion 701 is located in the thermal insulation layer 4, and can increase the contact area with the thermal insulation layer 4, thereby enhancing the friction force and increasing the fixing effect, and the second barb portion 702 is located in the metal layer 203.

[0061] Specifically, the third fixing member 7 fixes the insulation layer 4 and the plurality of keels 201 , the diameter of the mounting hole is smaller than the width of the third fixing member 7 , and the first barb portion 701 and the second barb portion 702 can prevent the third fixing member 7 from falling out after being vibrated.

[0062] It should be noted that the mounting hole is smaller than the width of the third fixing piece 7, so the third fixing piece 7 needs to be driven into the mounting hole by external force, so that the two are fixed more firmly, and the barbs fix the thermal insulation layer 4 and the metal layer 203 very well, and the barbs are arranged in several layers. Even if one layer of barbs is worn and falls off, the second layer of barbs still plays a fixing role. The third fixing piece 7 will not fall off until each layer of barbs is completely damaged, which greatly enhances the fixing effect.

[0063] In one embodiment, the protective layer 1 is arranged on the thermal insulation layer 4, the supporting layer 2 is located between the protective layer 1 and the thermal insulation layer 4, and the edge of the protective layer 1 is further provided with a skirt 8, and the inside of the skirt 8 is filled with soft thermal insulation material.

[0064] Specifically, the skirt 8 wraps the outdoor bathtub well to improve the overall thermal insulation effect.

[0065] In one embodiment, the soft thermal insulation material is one or more of aluminum foil, space cotton, pearl cotton, and XPE. The soft thermal insulation material is one or more of aluminum foil, space cotton, pearl cotton, and XPE. In this embodiment, space cotton is used for filling. The soft thermal insulation material in the utility model should not be limited to the materials listed above. As long as the material can achieve the thermal insulation effect, it should fall into the protection scope of the utility model.

[0066] Specifically, aluminum foil, space cotton, pearl cotton and XPE materials have better thermal insulation performance.

[0067] In one embodiment, the protective layer 1 is made of waterproof Oxford cloth, but the protective layer 1 in the present invention should not be limited to the materials listed above, and any material that can achieve the protective effect should fall within the protection scope of the present invention.

[0068] In one embodiment, the protective layer 1 is further provided with exhaust holes, and the exhaust holes are used to allow the air inside the bathtub cover to be discharged from the exhaust holes during the process of rolling up the bathtub cover, thereby reducing the volume of the bathtub cover caused by internal inflation.

[0069] In one embodiment, the edge of the protective layer 1 is provided with a plurality of drawstrings, and the drawstrings are provided with locks that are detachably connected to the bathtub. The locks can be conventional buckles used on backpack straps.

[0070] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model.
