Description

Technical Field

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

[0002] A new appliance, the water-heating blanket, has emerged in the consumer electronics market, offering similar functionality to electric blankets but significantly greater comfort. This blanket heats water with electricity and then passes it through pipes distributed throughout a fabric mat. This hot water circulates through the pipes, evenly distributing the heat throughout the fabric mat and providing warmth. Compared to traditional electric blankets, water-heating blankets typically include an additional peripheral: the main unit, which provides hot water and promotes its circulation. Unlike traditional electric blankets, water-heating blankets offer a less dry, more comfortable feel.

[0003] Since an additional water-heating blanket main unit is used to electrically heat the circulating water, it is inevitable that a loud noise will be generated when heating the water. This noise will gradually increase as the water temperature rises. This situation is obviously very unfavorable for a device used for sleeping. In the utility model patent with patent publication number CN221630038U, the water-heating blanket main unit is silenced by connecting a soundproof shell to the outside of the main unit, a soundproof cover detachably connected to the outside of the soundproof shell, and a soundproof member located between the soundproof shell and the soundproof cover. However, this obviously only blocks the spread of noise. In a quiet sleeping environment, the actual silencing effect is poor. Utility Model Content

[0028] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] refer to Figures 1 to 3 The utility model discloses a water heating blanket host provided by the utility model, including a circulating water tank 100 and a water circulation component 200 arranged near the circulating water tank 100, and also includes other necessary components, such as a shell 300, a cover body, a valve body and a water pipe.

[0032] The circulating water tank 100 has a heating chamber 110, and an electric heater 111 is provided inside the heating chamber 110. The electric heater 111 is used to heat the water in the circulating water tank 100. The heating chamber 110 can be convex or concave.

[0033] like Figure 3 As shown, the water circulation assembly 200 includes a water pump 210, a water inlet pipe 220, and a water outlet pipe 230. The water outlet pipe 230 is connected to the circulating water tank 100, and the water inlet pipe 220 is connected to the circulating water tank 100. The pipe opening of the water inlet pipe 220 is adjacent to the surface of the electric heater 111 and is spaced apart from the surface of the electric heater 111. One of the water inlet pipe 220 or the water outlet pipe 230 is connected to the water pump 210. In other words, the water inlet pipe 220 is directly connected to the water pump 210, and the water pump 210 inputs water into the circulating water tank 100 through the water inlet pipe 220, or the water outlet pipe 230 is directly connected to the water pump 210, and the water pump 210 pumps circulating water from the circulating water tank 100 through the water outlet pipe 230. Regardless of the method, a reciprocating circulating water flow will be formed in the circulating water tank 100, the water outlet pipe 230, the water inlet pipe 220 and the circulating pipe of the necessary water heating blanket. The water flow rate in the pipe is relatively high, and in the water inlet pipe 220, there is a circulating water flow with a relatively high flow rate entering the circulating water tank 100.

[0034] Since there is a certain distance between the mouth of the water inlet pipe 220 and the surface of the electric heater 111 and it is not attached to the surface of the electric heater 111, it can ensure that the circulating water in the water inlet pipe 220 can smoothly enter the circulating water tank 100. Moreover, the mouth of the water inlet pipe 220 is close to or adjacent to the surface of the electric heater 111, which ensures that the above-mentioned distance will not be too large. Under the drive of the water pump 210, the water flow released from the water inlet pipe 220 impacts the surface of the electric heater 111 at a certain rate, so that the circulating water on the surface of the electric heater 111 is in a fast-flowing state, which can ensure that the temperature of the circulating water heated by the electric heater 111 is low, and the heat generated by the electric heater 111 is taken away more efficiently, and the generation or accumulation of bubbles is effectively avoided, thereby reducing the sound produced by the bubble bursting.

[0035] The water heating blanket main unit provided by the present invention is configured with a water inlet pipe 220 near the surface of the electric heater 111 in the circulating water tank 100. Driven by the water pump 210, the cold water flow of the water inlet pipe 220 can directly impact the electric heater 111 at a certain flow rate, so that the water near the electric heater 111 keeps flowing and the water temperature is relatively low, thereby avoiding the formation of bubbles on the surface of the electric heater 111 and reducing the sound caused by the bursting of bubbles, thereby greatly reducing the noise generated by the water heating blanket main unit when heating the circulating water and improving the silent effect of the water heating blanket.

[0036] Optionally, in one embodiment of the present invention, Figures 1 to 3 As shown, the portion of the water inlet pipe 220 located in the circulating water tank 100 is a bent pipe. Bending the pipe causes the circulating water to change its direction sharply before entering the circulating water tank 100, which can increase the flow rate of the circulating water to a certain extent. By adjusting the pipe structure, the impact of the water flow in the water inlet pipe 220 on the surface of the electric heater 111 is increased. For details, refer to Figures 1 to 3 The bent pipe bends along the normal direction of the bottom surface of the circulating water tank 100. The normal direction of the bottom surface of the circulating water tank 100 makes the part of the water inlet pipe 220 in the circulating water tank 100 in an upright position, and the water flow in the water inlet pipe 220 first rises and then drops rapidly.

[0037] Optionally, in another embodiment of the present invention, referring to Figure 1 and Figure 2 The end face of the water inlet pipe 220 is parallel to the surface of the electric heater 111. The cross-section of the water inlet pipe 220 is typically circular, and with the end face of the water inlet pipe 220 parallel to the surface of the electric heater 111, the water in the water inlet pipe 220 can diffuse quickly and evenly in all directions. If the water inlet pipe 220 is a curved pipe and tilted relative to the surface of the electric heater 111, the end face of the water inlet pipe 220 becomes an elliptical shape, which covers a larger area.

[0038] Optionally, in another embodiment of the present invention, the orifice of the water inlet pipe 220 is a contraction orifice. By setting the orifice of the water inlet pipe 220 as a contraction orifice, the outlet of the water pipe becomes smaller, which can significantly increase the rate of water flowing out of the water inlet pipe 220.

[0039] Optionally, in a specific implementation of the present invention, refer to Figures 1 to 3 A limit frame 120 is provided on the bottom surface of the circulating water tank 100 next to the electric heater 111, and the water inlet pipe 220 passes through the limit frame 120. Since the water inlet pipe 220 freely extends into the circulating water tank 100 and water flows out of the water inlet pipe 220, if it is not limited, the water inlet pipe 220 will swing to a certain extent, making it difficult to ensure that the pipe opening of the water inlet pipe 220 is adjacent to the surface of the electric heater 111 and spaced apart from the surface of the electric heater 111. Therefore, a limit frame 120 is provided near the pipe opening of the water inlet pipe 220. The water inlet pipe 220 passes through the limit frame 120 and can only swing within the limit frame 120. Furthermore, a certain gap is provided between the water inlet pipe 220 and the limiting frame 120, that is, the water inlet pipe 220 does not contact the limiting frame 120, and the water inlet pipe 220 can still swing to a certain extent during operation. This allows the water inlet pipe 220, which has a much smaller area than the electric heater 111, to spray water more widely onto the surface of the electric heater 111. The water inlet pipe 220 can be made of an elastic material.

[0040] Specifically, in one embodiment of the present invention, referring to Figure 1 and Figure 2 The heating chamber 110 is a heating groove provided on the bottom surface of the circulating water tank 100. The electric heater 111 is a PTC heating plate, which is located at the bottom of the heating groove. The heating chamber 110 is configured as a groove, with the PTC heating plate located at the bottom. The nozzle of the water inlet pipe 220 faces the heating groove, allowing the circulating water to flow at a high rate within the heating groove.

[0041] Specifically, in another embodiment of the present invention, referring to Figures 1 to 4 The water heating blanket main unit also includes a housing 300 with a housing cover 310. The circulating water tank 100 and the water circulation assembly 200 are both disposed within the housing 300. The water pump 210 is disposed next to the circulating water tank 100. The joints of the water inlet pipe 220 and the water outlet pipe 230 are both disposed on the same end surface of the housing 300. The housing 300 can be a split structure, with the top surfaces of the upper and lower housings 300 forming the circulating water tank 100.

[0042] Specifically, in another embodiment of the present invention, referring to Figure 3 The water heating blanket host also includes a control circuit board 400, which is installed in the housing 300 below the circulating water tank 100. The control circuit board 400 is electrically connected to the water pump 210 and the electric heater 111 respectively.

[0043] The present invention also provides a water-heating blanket, comprising a blanket body and any of the aforementioned water-heating blanket main units; the water-heating blanket main unit is connected to the blanket body and supplies circulating water to the blanket body. The water-heating blanket provided by the present invention adopts a water-heating blanket main unit with a silent effect. By arranging a water inlet pipe 220 near the surface of the electric heater 111 in the circulating water tank 100, driven by a water pump 210, the cold water flow from the water inlet pipe 220 can directly impact the electric heater 111 at a certain flow rate, so that the water near the electric heater 111 keeps flowing and the water temperature is relatively low, thereby avoiding the formation of bubbles on the surface of the electric heater 111, thereby reducing the sound generated by the bursting bubbles, thereby significantly reducing the noise generated by the water-heating blanket main unit when heating the circulating water, and improving the silent effect of the water-heating blanket.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
