Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a water heating blanket. Background Art

[0002] A water-heating blanket is a heat preservation and heating device that uses water as a heat medium. It has many advantages such as safety, constant temperature, no electromagnetic radiation, no induced voltage, and arbitrary temperature adjustment. The water-heating blanket includes a water-heating blanket host and a water-heating blanket body. The water-heating blanket host is used to provide hot water circulation for the water-heating blanket body to ensure that the temperature of the blanket body remains unchanged. In the existing technology, when a water-heating blanket is used, a pipe is usually directly connected to the blanket body. The pipe is evenly laid inside the blanket body. After water is passed into one end of the pipe, the temperature inside the blanket body rises accordingly, and the two ends of the pipe are connected to the connector on one side of the blanket body. Existing water-heating blankets are usually equipped with a one-way valve in the water tank that can be effectively closed to prevent excessive water injection. However, once the water level in the water tank begins to drop, the one-way valve cannot automatically open to replenish water, which can easily lead to insufficient water level or even dry burning risks in subsequent use, posing a safety hazard during use. Utility Model Content

[0003] The purpose of the utility model is to solve the deficiencies of the above-mentioned technology and to provide a water heating blanket which can repeatedly heat water in a circulation manner and realize automatic water replenishment of the heating chamber through a floating closure, thereby avoiding the risk of insufficient water level or even dry burning in subsequent use and having better safety in use.

The valve assembly 2 includes a partition member 21, a pressure relief valve 22, and a floating closing member 23. The partition member 21 is detachably connected to the inner cavity of the water tank body 11 to separate the inner cavity of the water tank body 11 into a water storage chamber 3 and a heating chamber 4. The partition member 21 is fixed to the inner cavity of the water tank body 11 with bolts. The pressure relief valve 22 is arranged on the partition member 21. The bottom of the partition member 21 extends into the heating chamber 4 and is provided with a matching member 5. The interior of the matching member 5 is hollow and communicated with the water storage chamber 3. The bottom of the matching member 5 is provided with an inclined panel 9. The inclined panel 9 is penetrated by a through hole 501 that is communicated with the inner cavity of the matching member. Two docking plates 10 are symmetrically provided at the bottom of the inclined panel 9. A movable hole 1001 is opened at the bottom of the docking plate 10. The floating closing member 23 is fixedly connected to the swing arm 13. Coaxial movable shafts 1301 are provided on both sides of the swing arm 13. The movable shaft 1301 is rotatably connected to the corresponding movable hole 1001, so that the floating closing member 23 is rotatably connected to the bottom of the matching member 5, and the floating closing member 23 is provided with a plugging head 6 that is sealed and inserted in the through hole 501. The plugging head 6 is provided with an annular sealing gasket 14. The sealing gasket 14 is used to seal the through hole 501 and the plugging head 6. Preferably, the inner wall of the movable hole 1001 is provided with a notch groove 1002 penetrating the bottom of the docking plate 10 , and the movable shaft 1301 passes through the notch groove 1002 , thereby facilitating the disassembly and assembly of the floating closing member 23 from the partition member 21 .

[0022] The blanket body 7 includes a water channel 701. A first connecting pipe 702 is provided at one end of the water channel 701, which communicates with the water storage chamber 3. A second connecting pipe 703 is provided at the other end of the water channel 701, which communicates with the heating chamber 4 and houses the heater 8. The inclined plate 9 is tilted toward the second connecting pipe 703, guiding the liquid in the water storage chamber 3 into the heating chamber 4 through the through hole 501.

[0023] The heater 8 includes a PCT heating element 81, a first rubber adapter 82, and a second rubber adapter 83. The side of the PCT heating element 81 near the water tank body 11 is sleeved with the first rubber adapter 82.

[0024] The water heating blanket divides the inner cavity of the water tank body 11 into a water storage chamber 3 and a heating chamber 4 through the partition member 21 of the valve assembly 2. The liquid in the water storage chamber 3 is injected into the heating chamber 4 through the through hole 501 of the matching member 5. When the liquid in the heating chamber 4 is full, the floating closing member 23 rotates upward with the help of the buoyancy of the liquid in the heating chamber 4, so that the plug 6 is inserted into the through hole 501, closing the connection between the water storage chamber 3 and the heating chamber 4. At the same time, the heater 8 starts to heat the liquid in the heating chamber 4, and the PTC heating element raises the temperature of the liquid in the heating chamber 4 to about 75 degrees Celsius to generate high pressure. After the liquid in the heating chamber 4 is heated and generates high pressure, it enters the water channel 701 in the blanket body 7 through the second connecting pipe 703, and then provides heating for the user. In this process, the pressure relief valve 22 is used to release the excessive pressure in the heating chamber 4. The liquid in the water channel 701 enters the water storage chamber 3 through the first connecting pipe 702. When the heating chamber 4 is short of water due to overflow of the heated liquid, the floating closing member 23 rotates downward with the help of its own gravity, causing the plug 6 to disengage from the through hole 501, thereby opening the connection between the water storage chamber 3 and the heating chamber 4. The liquid in the water storage chamber 3 is injected into the heating chamber 4 again through the through hole 501 of the matching member 5, thereby forming circulating heating. The water heating blanket can repeatedly heat the water in a circulating manner, and automatically replenish water in the heating chamber 4 through the floating closing member 23, thereby avoiding the risk of insufficient water level or even dry burning in subsequent use, and has better safety in use.

[0025] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
