Description

Technical Field

[0001] This utility model relates to the field of thermal insulation products, and in particular to a bathtub thermal insulation blanket. Background Technology

[0002] Many people enjoy taking hot baths in the bathtub, but currently, taking a hot bath in the bathtub has relatively high requirements for the environment. That is, the temperature around the bathtub cannot be too low. If the air temperature around the bathtub is low (for example, the air temperature is only -5 degrees Celsius), it will cause the water in the bathtub to cool down quickly. The rapid cooling of the water in the bathtub can easily cause people to catch a cold. Therefore, in order for people in cold regions (including but not limited to high-latitude regions) to be able to take a bath in the bathtub, it is necessary to keep the water in the bathtub warm. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a bathtub heating blanket that can prevent heat from the water in the bathtub from dissipating into the air too quickly, thereby maintaining the temperature of the water in the bathtub, preventing the water from cooling down too fast, and prolonging the bathing experience for the user.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A bathtub bathing heat preservation blanket includes a pearl cotton layer, an OPP film layer, and an aluminum foil layer. The OPP film layer and the aluminum foil layer are respectively disposed on both sides of the pearl cotton layer. The thickness of the pearl cotton layer is greater than the thickness of the OPP film layer and the thickness of the aluminum foil layer. The pearl cotton layer, OPP film layer, and aluminum foil layer are laminated together to form a blanket body. The blanket body has a notch. The pearl cotton layer, OPP film layer, and aluminum foil layer are of the same shape and size. A soft rubber retaining ring is provided at the notch.

[0006] The method of using this type of heat-insulating blanket is as follows: First, the bather soaks in the bathtub, and then the entire blanket is placed on the water surface, with the OPP film layer on top and the aluminum foil layer in contact with the water surface. The bather's head is exposed through the opening. Because the blanket, which is made up of pearl cotton layer, OPP film layer and aluminum foil layer, has good barrier properties, it can prevent the heat in the bath water from being lost to the air too quickly, thereby keeping the water in the bathtub warm and preventing the water in the bathtub from cooling down too quickly, thus prolonging the bathing experience.

[0007] It should be further noted that this type of blanket needs to be cut according to the shape of the bathtub (or tub) before use so that the blanket can fit perfectly inside the bathtub.

[0008] In this thermal blanket, both the aluminum foil layer and the pearl cotton layer have excellent heat insulation properties. The soft rubber guard ring helps prevent scratches on the user's neck.

[0009] Optionally, a PE film layer is also included, which is disposed on one side of the aluminum foil layer, and the pearl cotton layer and the PE film layer are respectively located on both sides of the aluminum foil layer, and the shape and size of the PE film layer are the same as those of the aluminum foil layer.

[0010] A PE film layer is placed on one side of the aluminum foil layer. When the entire insulation blanket is placed on water, the PE film layer is in contact with the water surface. The PE film layer has good barrier properties against water vapor and water, which can prevent water vapor and water from seeping upward through the PE film layer.

[0011] The thickness of the PE film is approximately equal to the thickness of the OPP film.

[0012] Optionally, a bubble wrap layer is also included, which is disposed between the aluminum foil layer and the pearl cotton layer, wherein the thickness of the pearl cotton layer is greater than the thickness of the bubble wrap layer.

[0013] A bubble wrap layer is further added between the aluminum foil layer and the pearl cotton layer. This serves two purposes: firstly, to further improve the overall thermal insulation performance of the blanket, and secondly, to improve the buoyancy of the blanket, ensuring that the entire blanket can float stably on the water surface. The thickness of the bubble wrap layer is 0.5 cm to 1 cm.

[0014] Optionally, the soft rubber retaining ring is provided with an annular groove, one end of the blanket is inserted into the annular groove, the PE film layer is bonded to one side wall of the annular groove, and the OPP film layer is bonded to the other side wall of the annular groove.

[0015] Specifically, the OPP film and PE film are located on both sides of the blanket body to ensure that the entire blanket body can be bonded and fitted together with the two side walls of the ring groove.

[0016] Optionally, the soft rubber retaining ring includes, but is not limited to, retaining rings made of silicone material.

[0017] Optionally, the thickness of the pearl cotton layer is 0.5 cm to 1 cm.

[0018] Optionally, the thickness of the OPP film layer is 40 micrometers to 50 micrometers.

[0019] Optionally, the thickness of the aluminum foil layer is 10 micrometers to 20 micrometers.

[0020] The beneficial effects of this utility model are: it can prevent the heat in the water in the bathtub from being lost into the air too quickly, thereby achieving the goal of keeping the water in the bathtub warm, preventing the water in the bathtub from cooling down too quickly, and prolonging the bathing experience for the bather.
