Description

Technical Field

[0001] The utility model relates to the technical field of electric blanket overload protection, in particular to an electric blanket overload protection device. Background Art

[0002] Long-term use of an electric blanket can cause low-temperature scalding to the human body. Low-temperature scalding, also known as low-temperature burn or low-heat burn, refers to the situation where the body is in contact with a heat source with not-too-high temperature for a long time, resulting in heat accumulation and causing burns to the skin and subcutaneous tissues at the contact site.

[0003] Moreover, the long-term high-temperature use of the electric blanket reduces the service life of the electric blanket and even has the risk of overload. Overload will cause the internal temperature of the electric blanket to rise sharply, which may lead to a fire or damage the electric blanket itself. Therefore, an electric blanket overload protection device is needed. Content of the Utility Model

[0004] (I) Technical Problems to be Solved

[0008] The electronic control circuit breaker is installed on the power line of the electric blanket and is used to cut off the power of the electric blanket to avoid overload of the electric blanket;

[0009] A touch screen component is arranged on the upper surface of the intelligent controller and is used to display and control the operating parameters of the air pump electric blanket overload protection device. The air outlet end of the [air pump] is fixedly connected with a connecting tee hose, and heat dissipation protection components are arranged at both outlets of the connecting tee hose;

The tree-shaped heat dissipation component includes a branch air hose, an air outlet rubber head, a temperature sensor, a rubber column, a gradient cut and a solenoid valve.

[0012] Note: There seems to be a missing word "air pump" in the description of the touch screen component in line 31. I added it in the translation for the sake of a complete and understandable sentence. If this is not what you intended, please correct the original text and I will adjust the translation accordingly.Preferably, the bronchial hose in the tree-shaped heat dissipation component is fixedly connected to the side flat hose, and the solenoid valve is arranged at the position where the bronchial hose communicates with the side flat hose.

A plurality of rubber columns are fixedly connected to the edge positions in the air outlet slots. The rubber columns are used to support the air outlet slots.

[0034] A plurality of tree-shaped heat dissipation components are arranged on the side flat hose 4, and the plurality of tree-shaped heat dissipation components are evenly distributed at equal intervals. The tree-shaped heat dissipation component includes a branch air hose 5, an air outlet rubber head 6, a temperature sensor 7, a rubber column 11, a gradient cut 12 and a solenoid valve 17.

[0035] Further, the branch air hose 5 in the tree-shaped heat dissipation component is fixedly connected to the side flat hose 4, the solenoid valve 17 is arranged at the position where the branch air hose 5 communicates with the side flat hose 4, the solenoid valve 17 is used to control the communication between the branch air hose 5 and the side flat hose 4, and the solenoid valves 17 are all electrically connected to the intelligent controller 13.

[0036] Further, a plurality of installation grooves 9 for installing the air outlet rubber head 6 are opened on one side of the branch air hose 5, the plurality of installation grooves 9 are inclined at an angle of 45° and are equidistantly arranged, and a plurality of the same installation grooves 9 are opened on the other side of the side flat hose 4. The installation grooves 9 on both sides of the branch air hose 5 are distributed in a tree-shaped and staggered manner.

[0037] Furthermore, air outlet rubber heads 6 are fixedly installed in multiple installation grooves 9. The gradient incisions 12 are all opened at one end of the air pump 1 where the multiple air outlet rubber heads 6 extend into the installation grooves 9. The overall trend of the gradient incisions 12 on the multiple air outlet rubber heads 6 is in a gradually narrowing form. The gradient incisions 12 can improve the uniformity of the air flow output during the transmission process.

[0038] Furthermore, air outlet slots 10 are opened on the outer surfaces of the multiple air outlet rubber heads 6 at the ends away from the gradient incisions 12.

[0040] Furthermore, during use, by connecting the set electric control circuit breaker 16 to the electric blanket and laying this electric blanket overload protection device on the electric blanket, the outer shapes of the set side flat hose 4, branch air hose 5 and air outlet rubber head 6 are rubber flat tubes.

This enables the temperature of the electric blanket to drop rapidly, avoiding the low-temperature burns caused by long-term high temperature to the human body and the reduction of the service life caused by too high temperature of the electric blanket, and also improving the safety of using the electric blanket.

[0044] Furthermore, when the air enters the branch air hose 5, due to the gradually narrowing shape of the overall trend of the gradually changing cuts 12 on the multiple air outlet rubber heads 6 provided, each air outlet rubber head 6 can receive uniform air flow better, improving the uniformity of the air flow output during the transmission process, and avoiding the problem of too small air flow at the air outlet rubber head 6 at the end of the branch air hose 5 and low heat dissipation efficiency.

[0045] Working principle: When the temperature sensor 7 detects that the temperature of the electric blanket is too high, it will send a signal to the intelligent controller 13. The intelligent controller 13 temporarily cuts off the power supply of the electric blanket through the electric control circuit breaker 16. At this time, the air pump 1 starts. The air pump 1 will transport air into the branch air hose 5 through the connecting three-way hose 2, connecting flat tube 3, and side flat hose 4 until the air blows out from the rubber column 11 to blow away the heat dissipated by the electric blanket. This enables the temperature of the electric blanket to drop rapidly, avoiding the low-temperature burns caused by long-term high temperature to the human body and the reduction of the service life caused by too high temperature of the electric blanket, and also improving the safety of using the electric blanket.

[0046] When the air enters the branch air hose 5, due to the gradually narrowing shape of the overall trend of the gradually changing cuts 12 on the multiple air outlet rubber heads 6 provided, each air outlet rubber head 6 can receive uniform air flow better, improving the uniformity of the air flow output during the transmission process, and avoiding the problem of too small air flow at the air outlet rubber head 6 at the end of the branch air hose 5 and low heat dissipation efficiency.

[0047] By arranging multiple temperature sensors 7 evenly distributed at various positions on the surface of the electric blanket, the temperature of each position of the electric blanket can be effectively detected, improving the accuracy of the temperature detection of the electric blanket and ensuring the stable and effective safety of using the electric blanket.

[0048] By arranging multiple rubber columns 11 in the air outlet slot 10, the air outlet slot 10 can be effectively supported, avoiding the problem that its own flattening affects the uniformity of air flow dissipation, improving the heat dissipation efficiency, and also avoiding the problem that the air flow is blocked and affects the service life of the air pump 1.

[0049] By setting the shapes of the laterally flattened hose 4, the bronchial hose 5, and the air outlet rubber head 6 as rubber flat hoses, this can largely avoid the influence of the pipeline on the user's comfort during use, and after it is subjected to the pressure from the user's own gravity, the rubber flat hose will not produce excessive deformation, thus affecting the air flow transmission efficiency problem.
