Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a novel electric blanket. Background Technology

[0002] An electric blanket, also known as an electric mattress, is a contact-type electric heating appliance. It incorporates specially designed, high-insulation-performance soft cable heating elements into the blanket in a serpentine pattern, generating heat when powered on.

[0003] When not in use, electric blankets need to be stored. Since electric blankets contain heating elements, folding should be avoided when storing them. Because electric blankets are soft, they are relatively troublesome to store, and storing them flat takes up a lot of space. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a new type of electric blanket, which aims to solve the problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A new type of electric blanket includes:

[0007] The blanket body, wherein a controller is mounted on one outer wall of the blanket body; and

[0008] An anti-folding mechanism includes a mounting ring, which is fixedly connected to the outer surface of the blanket. Two support bags are connected between the outer walls of the mounting ring. An inflation cavity is provided between each support bag and the interior of the mounting ring. An inflation nozzle is connected to one side of the outer wall of the mounting ring.

[0009] As a preferred embodiment of this utility model, a sealing sleeve is provided on the outer surface of the inflation nozzle via a threaded sleeve.

[0010] As a preferred embodiment of this utility model, the mounting ring and the two support bags are both made of TPU material.

[0014] Beneficial effects

[0015] Compared with the prior art, this utility model provides a novel electric blanket with the following beneficial effects:

[0016] 1. In this solution, the controller is connected to the blanket body via a cable. The controller has a plug for easy heating of the blanket body. The mounting ring surrounds the four edges of the blanket body, and the support bag is connected to the inner walls on both sides of the mounting ring and fixed to the bottom of the blanket body. The air nozzles can be used to easily inflate the air cavities inside the mounting ring and support bag. The air pressure inside the inflated air cavities forms a rigid support, providing support for the blanket body, preventing the blanket body from bending and affecting the use of the internal heating elements, and improving the safety of the blanket body during loading and unloading.

[0017] 2. In this design, the sealing sleeve facilitates the sealing of the inflation nozzle, improving the effectiveness of the anti-bending mechanism.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Example:

[0026] Please see Figure 1-4 A new type of electric blanket, comprising:

[0027] Blanket body 1, with controller 2 installed on one outer wall of blanket body 1; and

[0028] The anti-folding mechanism 3 includes a mounting ring 301, which is fixedly connected to the outer surface of the blanket body 1. Two support bags 302 are connected between the outer walls of the mounting ring 301. An inflation cavity 303 is provided between each support bag 302 and the interior of the mounting ring 301. An inflation nozzle 304 is connected to one side of the outer wall of the mounting ring 301.

[0029] In this embodiment, the controller 2 is connected to the blanket 1 via a cable. The controller 2 is equipped with a plug to facilitate heating of the blanket 1. This is prior art and will not be described in detail. The mounting ring 301 surrounds the four edges of the blanket 1. The support bag 302 is connected to the inner walls on both sides of the mounting ring 301 and is fixed to the bottom of the blanket 1. The air nozzle 304 facilitates the inflation of the air cavity 303 inside the mounting ring 301 and the support bag 302. After inflation, the air pressure inside the air cavity 303 forms a rigid support, preventing the blanket 1 from bending and affecting the use of the internal heating element, thus improving the safety of the blanket 1 during storage.

[0030] Please refer to the specific details. Figure 3-4 As shown, a sealing sleeve 305 is threaded onto the outer surface of the air inlet 304.

[0031] In this embodiment, the sealing sleeve 305 facilitates the sealing of the air nozzle 304, thereby improving the effectiveness of the anti-bending mechanism 3.

[0032] Please refer to the specific details. Figure 1-2 As shown, the mounting ring 301 and the two support bags 302 are all made of TPU material.

[0033] In this embodiment, the mounting ring 301 and the two support bags 302 are both made of TPU material to improve their strength, avoid rupture during inflation, and improve the safety of the anti-folding mechanism 3.

[0034] Please refer to the specific details. Figure 3 As shown, pressure sensors 4 are installed at the four corners of the blanket 1, and temperature monitors 5 are installed on the blanket 1.

[0035] In this embodiment, a pressure sensor 4 is installed on the blanket 1. The pressure sensor 4 is a thin-film pressure sensor. The pressure sensor 4 detects whether someone is lying on the electric blanket, realizing automatic power on and off, avoiding continuous heating and wasting energy when no one is on it. At the same time, there is a vibration sensor at the end of the controller 2. In normal mode, the power is cut off after a timer. If the no-person detection mode is turned on, the blanket 1 stretches and deforms on the soft bed, and the vibration signal is transmitted to the controller to keep it powered on. If there is no vibration within 10 seconds, the power is cut off, and the power is restored when the next vibration is detected. The temperature is monitored by the temperature monitor 5. If the blanket 1 is overheated, the power is cut off to improve the safety of the blanket 1. The pressure sensor 4 and the temperature monitor 5 are existing technologies and will not be described in detail here.

[0036] Please refer to the specific details. Figure 3 As shown, a protective layer 6 is provided inside the blanket body 1, and the protective layer 6 is made of bamboo charcoal fiber.

[0037] In this embodiment, the protective layer 6 is made of bamboo charcoal fiber. The protective layer 6 facilitates the adsorption of odors and the release of negative ions. At the same time, a liquid made of nano-level tourmaline powder, called a negative oxygen ion generator, is sprayed on the surface of the blanket 1. After the surface dries, an electrostatic potential difference is formed, which causes the surrounding air to be ionized, thereby generating free electrons. The free electrons combine with oxygen in the air to produce negative oxygen ions. Negative oxygen ions are negatively charged air molecules that can purify indoor air by adsorbing pollutants such as bacteria, viruses, and dust in the air, which is beneficial to human health.

[0038] Please refer to the specific details. Figure 2 As shown, an alarm 7 is installed on the controller 2.

[0039] In this embodiment, the alarm 7 can be used to trigger an alarm when the blanket 1 exceeds the temperature, thereby further improving the safety of using the blanket 1.

[0040] Working principle: When the blanket 1 needs to be stored, open the sealing sleeve 305 and inject air into the inflation cavity 303 inside the mounting ring 301 and support bag 302 through the air inlet 304. The air pressure inside the inflation cavity 303 after inflation forms a rigid support, providing support for the blanket 1 and keeping the blanket 1 in an unfolded state. This makes it easy to store the blanket 1 without taking up too much space.

[0041] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
