Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture, and if the specific posture is changed, the directional indications are changed accordingly.

Referring to fig. 1 to 3 together, the embodiment of the present invention provides a heating member 120 for heating a water heating blanket. The heating part 120 has a second water flow path 121 inside. The warming-in-water blanket includes a blanket body 110. The blanket body 110 has a first water flow passage 111. The second water flow passage 121 of the heating member 120 is communicated with the first water flow passage 111 of the blanket body 110. The heating member 120 includes a ceramic tube 122 and a heating film 123 disposed on the ceramic tube 122. The heat generating film 123 is used for heating the circulating water on the second water flow channel 121.

The ceramic tube 122 has a hollow tubular structure. In this embodiment, the outer diameter Φ of the ceramic pipe 122 ranges from 7.8mm to 9.8 mm. The wall thickness t of the ceramic tube 122 is greater than or equal to 2 mm. The ceramic tube 122 is made of a polycrystalline ceramic composite material, such as a silicon oxide composite material, an aluminum oxide composite material, or the like. The value range of the outer diameter phi of the ceramic pipe body 122 is set to be 7.8 mm-9.8 mm, and the wall thickness t of the ceramic pipe body 122 is set to be more than or equal to 2mm, so that the purpose is that:

on one hand, the structure can stabilize the structure of the ceramic tube 122 and has high strength, so that the ceramic tube 122 is not easy to damage;

on the other hand, the ceramic wall thickness of 2mm or more can ensure that the ceramic tube 122 is not broken down during the energization heating process, thereby improving the safety of the heating member 120.

It can be understood that the value of the outer diameter Φ of the ceramic pipe 122 cannot be too large, and if the outer diameter Φ of the ceramic pipe 122 is too large, the heat-generating film 123 disposed on the ceramic pipe 122 has a too long heat-conducting path, and is not favorable for rapid heating of the circulating water in the second water flow channel 121. If the outer diameter Φ of the ceramic pipe 122 is too small, on the one hand, the physical strength may be insufficient to cause easy breakage; on the other hand, when the outer diameter Φ of the ceramic pipe 122 is too small, it imposes a certain limitation on the sectional area of the water flow path inside the ceramic pipe 122, so that the circulating water in the heated second water flow channel 121 cannot be quickly injected into the first water flow channel 111 of the blanket body 110.

The heating film 123 covers the outer wall surface of the ceramic tube 122. The heat generating film 123 is provided to heat the circulating water flowing through the second water flow path 121. In this embodiment, the heat generating film 123 is made of tin oxide or a composite material thereof. The heating film 123 is uniformly sprayed on the outer wall surface of the ceramic tube 122. The thickness of the heating film 123 ranges from 3 μm to 8 μm.

In this embodiment, since the polycrystalline ceramic composite material used for the ceramic tube 122 has high strength and heat resistance, the heating is performedThe thermal load of the component 120 may reach 100W/cm²Thereby, the heating part 120 can realize high-power rapid heating. The volume of the heating component 120 can be made smaller with the same power.

The heat generating film 123 is not limited to be formed on the outer wall surface of the ceramic tube 122 by thermal spraying, and may be formed by other methods such as coating, as required. If necessary, the heat generating film 123 may be prepared in advance, and then the heat generating film 123 may be attached to the surface of the ceramic tube 122. That is, the arrangement of the heat generating film 123 and the ceramic pipe 122 may be various as long as the heat generating film 123 can heat the circulating water flowing through the second water flow path 121 of the ceramic pipe 122.

In the heating member 120 according to the embodiment of the present invention, the second water flow passage 121 is formed inside the ceramic pipe 122. The outer wall surface of the ceramic pipe 122 is provided with a heating film 123 for heating the circulating water flowing through the second water flow path 121. Meanwhile, the second water flow channel 121 of the ceramic pipe 122 is communicated with the first water flow channel 111 of the blanket body 110 of the water heating blanket. The structure of the heating member 120 has the following advantages:

on one hand, since the ceramic tube 122 has a good thermal conductivity, the heat generated by the heating film 123 during the power-on process can be effectively transferred to the second water channel 121 through the wall of the ceramic tube 122. At this time, the heat generating film 123 may heat the circulating water in the second water flow channel 121 while the circulating water flows through the second water flow channel 121.

On the other hand, because the ceramic tube 122 has better insulating properties, it can make effectively realize electrical isolation between the heating film 123 that sets up on the outer wall of ceramic tube 122 and the circulating water that circulates on the inner wall of ceramic tube 122 to well realized the insulating effect of water and electricity complete isolation.

The heating film 123 is provided on the outer wall surface of the ceramic tube 122 by thermal spraying, and completely covers the outer wall surface of the ceramic tube 122. The heating film 123 can heat the circulating water in the second water flow channel 121 in an all-directional manner by 360 degrees. This heating method can improve the rate of temperature rise of the blanket body 110 on the one hand, and on the other hand can also avoid the play of the inside rivers of ceramic body 122 to make the temperature of water even.

The first electrode 124 and the second electrode 125 are covered on the surface of the heat generating film 123, and are in electrical contact with the heat generating film 123.

If necessary, the inlet of the second water flow channel 121 can be disposed near the second end of the ceramic tube 122; the water outlet of the second water flow channel 121 can also be arranged near the first end of the ceramic tube 122; as long as it is possible to realize that the first electrode 124 and the second electrode 125 are disposed at opposite ends of the ceramic body 122.

Specifically, in this embodiment, the first electrode 124 and the second electrode 125 have the same or similar shapes. The specific shape and arrangement of the electrodes will be described below by taking only the first electrode 124 as an example.

On the other hand, a terminal of an external power feeding wire may be provided on the through-hole 1244 or on the fixing member, thereby securing stability of electrical contact between the terminal of the power feeding wire and the first electrode 124. The structure of the second electrode 125 is the same as or similar to that of the first electrode 124, and is not described in detail herein.

In one embodiment, the heating component 120 further includes a first interface component 126 and a second interface component 127.

The second seal 129 is disposed between the second interface member 127 and the ceramic body 122. The second sealing gasket 129 is used to seal the second interface part 127 and the ceramic tube 122, so that the circulating water of the warming-in-water blanket does not flow out of the gap between the second interface part 126 and the ceramic tube 122 when flowing through the heating part 120. In this embodiment, the first seal 128 and the second seal 129 are made of silicone material.

Specifically, the thermostat 1217 is located on the second side 1212 of the metal housing 1210 and between the first electrode 124 and the second electrode 125. The temperature controller 1217 is provided to prevent the ceramic tube 122 from being dried.

When the ceramic tube 122 is dry-fired, the temperature of the metal housing 1210 rapidly rises. When the temperature controller 1217 detects that the temperature of the metal housing 1210 exceeds a predetermined temperature, the temperature controller 1217 cuts off the electrical connection between the external power supply line and the first electrode 124 or the second electrode 125, thereby preventing the temperature of the ceramic tube 122 from increasing.

The heating part 120 may be assembled together by:

a ceramic tube body 122 is provided. The outer wall surface of the ceramic tube 122 is provided with a heating film 123.

The first electrode 124 is fixed to one end of the ceramic tube 122, and the second electrode 125 is fixed to the other end of the ceramic tube 122. At the same time, good electrical contact between the first electrode 124 and the second electrode 125 and the heat generating film 123 is ensured. The first electrode 124 and the second electrode 125 are further reserved with a certain distance from the outermost side of the ceramic tube 122 for disposing a first sealing gasket 128 and a second sealing gasket 129.

A first gasket 128 is fitted over the side of the ceramic tube 122 where the first electrode 124 is disposed, and a second gasket 129 is fitted over the side of the ceramic tube 122 where the second electrode 125 is disposed.

The first connection end 1282 and the second connection end 1283 of the first sealing gasket 128 and the second sealing gasket 129 can be sleeved on the outer wall surface of the ceramic tube 122 as required.

The end of the ceramic tube 122, on which the first sealing gasket 128 is mounted, is embedded inside the first interface member 126, and the end of the ceramic tube 122, on which the second sealing gasket 129 is mounted, is embedded inside the second interface member 127, so that the ceramic tube 122 is connected to the first interface member 126 and the second interface member 127.

The ceramic tube 122 provided with the first interface member 126 and the second interface member 127 is placed into the internal cavity of the metal case 1210 from the side of the metal case 1210, and the connection pipe 1262 is exposed to the outside of the metal case 1210.

When mounting, since the first side 1211 of the metal housing 1210 is a mounting surface (i.e., a surface of the metal housing 1210 attached to an external device), it should be noted that the first side plate 1264 of the fixing frame 1261 is disposed at a position corresponding to the first side 1211 of the metal housing 1210.

Meanwhile, it is also ensured that the position of the first electrode 124 corresponds to the position of the first opening 1215 on the second side 1212 of the metal housing 1210; and to ensure that the position of the second electrode 125 corresponds to the position of the second opening 1216 in the second side 1212 of the metal housing 1210.

Fixing a first side plate 1264 of the fixing frame 1261 and a first side surface 1211 of the metal shell 1210 by using a fixing piece such as a bolt; and fixing the second side plate 1265 of the fixing bracket 1261 and the third side 1213 of the metal case 1210 by using a fixing member such as a bolt.

A hose is attached to the connecting tubes 1262 of the first and

second interface parts

126 and 127 to fit into the water flow path of the warming blanket.

An external electrical connection wire is connected to the first electrode 124 through the first opening 1215, and an external electrical connection wire is connected to the second electrode 125 through the second opening 1216, thereby supplying power to the heat generating film 123.

The heating element 120 is a hollow structure and is directly connected in series to the water path of the water heating blanket. The heating unit 120 may be used as a heating function of the warming-in-water blanket, and may also be used as a water pipe of the warming-in-water blanket, so as to effectively utilize space and reduce the volume of the warming-in-water blanket product.

Referring to fig. 8, another embodiment of the present invention further provides a main unit 100 of a warming blanket. The hydro-thermal blanket main unit 100 provides circulating water to the blanket body 110. The warming-in-water blanket main unit 100 includes a heating part 120, a water tank 130, and a water pump 140.

The blanket body 110 has a first water flow passage 111. In one embodiment, the carpet body 110 may comprise two overlapped carpets. A heat conducting pipe is arranged between the blankets. The first water flow passage 111 is provided inside the heat conductive pipe. When the hot water flows in the first water flow passage 111, the heat of the hot water can be transferred to the blanket through the heat conductive pipe, so that the temperature of the blanket is increased to achieve the effect of heating the blanket body 110.

The heating component 120 is the heating component 120 according to any of the above embodiments.

The water tank 130 is used for containing circulating water. The circulating water in the water tank 130 flows back to the water tank 130 after passing through the second water flow path 121 of the heating part 120 and the first water flow path 111 of the blanket body 110.

In this embodiment, the water tank 130 has a water outlet 131 and a water inlet 132. The water inlet 132 is in communication with the first water flow passage 111. The water outlet 131 is communicated with the second water flow channel 121.

A water level detecting device (not shown) may be further provided in the water tank 130, as needed, for detecting the water storage amount in the water tank 130. When the water level detecting means detects that the amount of the circulating water in the water tank 130 is insufficient, the operation of the warming blanket main unit 100 may be stopped.

The water pump 140 is connected between the water outlet 131 of the water tank 130 and the heating part 120, and is used for delivering the circulating water in the water tank 130 to the first water flow channel 111 of the carpet body 110. When the water pump 140 is in operation: on one hand, the water pump 140 will pump the cold water in the water tank 130 out of the water outlet 131 and then fill the first water flow channel 111 of the blanket body 110; on the other hand, since the water tank 130, the second water flow channel 121 and the first water flow channel 111 form a circulating water flow path, the water in the first water flow channel 111 of the blanket body 110 is also returned to the water tank 130 through the water inlet 132 by the driving of the water pump 140.

The operation process of the main unit 100 of the water heating blanket is as follows:

during the heating operation, the water pump 140 and the heating part 120 are turned on. After the water pump 140 is turned on, the circulating water in the water tank 130 flows out through the water outlet 131, and is delivered to the first water flow channel 111 of the blanket body 110 through the second water flow channel 121 of the heating component 120. Since the heating parts 120 are simultaneously turned on, the circulating water in the second water flow channel 121 is heated and then delivered to the first water flow channel 111 of the blanket body 110. When the hot water flows in the first water flow channel 111, the heat of the hot water may be transferred to the blanket body 110 through the heat conductive pipe inside the blanket body 110 to achieve the effect of heating the blanket body 110. Compared with the conventional way of arranging the heating pipe in the water tank, the heating component 120 in the embodiment only needs to heat the circulating water flowing through the second water flow channel 121 inside, so that the heating component has the advantage of fast temperature rising speed. In addition, since the heating layer 123 of the heating member 120 is uniformly coated on the outer wall of the ceramic pipe 122, when the heating member 120 heats the circulating water in the second water flow channel 121, 360-degree three-dimensional heating can be realized. This heating method can improve the rate of rise of temperature of blanket body 110 on the one hand, and on the other hand also can avoid heating the drunkenness of the inside rivers of cavity to make the temperature of water even. In addition, since the heating member 120 is disposed close to the blanket body 110, the heated circulating water flows out of the heating member 120 and then directly flows into the first water flow channel 111 of the blanket body 110, so that heat loss caused by hot water flowing through the pipeline can be further reduced.

Still another embodiment of the present invention further provides a warming blanket, which comprises a blanket body 110 and the warming blanket main unit 100 as described in any of the above embodiments. In the water heating blanket, the blanket body 110 has a first water flow passage 111. The water heating blanket main machine 100 provides circulating water for the blanket body 110 when in work. Since the water heating blanket includes the water heating blanket main unit 100 according to any of the above embodiments, the technical effects of the water heating blanket provided by the present invention and the water heating blanket main unit 100 according to any of the above embodiments are also completely the same, and are not described herein again.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
