Description

Technical Field

[0001] This utility model relates to the field of water-heated blanket technology, specifically to a residual water removal structure inside a water-heated blanket. Background Technology

[0002] During use, the water used as the heat transfer medium in water-heated blankets is repeatedly circulated and heated. Over time, scale can easily form, requiring the water in the blanket to be replaced. At the end of each season, the water also needs to be drained for easier storage. Currently, most water-heated blankets on the market use a manual drainage method, which involves using an air pump to inflate the blanket and use air pressure to expel the water. This process is laborious.

[0003] Moreover, the water blankets currently on the market require the drain pipe to be unplugged from the main unit interface to drain. When the drain pipe is unplugged, the water inside the water blanket will immediately overflow and flood the surrounding environment. Even if a water container is prepared in advance, water will inevitably splash onto the ground, thus giving customers a bad experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a reasonable structure for draining residual water inside a water-heated blanket that is inflatable, drains easily, and is not afraid of water splashing, so as to overcome the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: A residual water removal structure for a water-heated blanket is provided, comprising a main unit and a water blanket. The main unit is characterized by having a warm water circulation mode and a residual water discharge mode. The main unit contains a water pump, a water tank, a heating element, and an air pump. The main unit casing is provided with a first interface, a second interface, and a third interface. The water blanket is provided with an inlet pipe and an outlet pipe. A warm water circulation loop is formed by connecting the water tank, water pump, heating element, first interface, inlet pipe, water blanket, outlet pipe, and second interface. The air pump is connected to the third interface. A drainage mechanism is provided in the inlet pipe, including a three-way drain pipe. When the main unit is in the residual water discharge mode, the outlet pipe is removed from the second interface and connected to the third interface, and the drain outlet of the three-way drain pipe is adjusted from a closed state to an open state.

[0006] The drainage mechanism also includes a drain outlet protective shell and a T-shaped pipe cover.

[0007] A cooling fan is installed below the heating element.

[0008] The drain outlet protective shell covers the three-way drain pipe and the water inlet pipe, and the three-way pipe cap is connected to the drain outlet protective shell.

[0009] The drain outlet protective shell is made of silicone rubber.

[0010] The above technical solution has the following beneficial effects:

[0011] 1) This utility model has a three-way drain pipe on the water outlet pipe. The three-way drain pipe can be connected to a water pipe. Before draining, the other end of the water pipe connected to the three-way drain pipe is led to the water receiving container, which facilitates drainage and can effectively prevent water splashing during drainage. The main unit is equipped with an air pump and an air pump interface, which can ensure that the residual water in the water blanket is effectively drained without affecting the circulation loop of the drain pipe.

[0012] 2) When it is necessary to replace the water in the water blanket, first pull out the T-joint cap so that the water in the circulating water circuit can be discharged from the drain outlet of the T-joint drain pipe. At this time, the water pump runs while the water in the circuit is discharged from the T-joint drain pipe and collected by the water basin. When it is necessary to drain the residual water in the water blanket, pull out the outlet pipe from the second interface and then insert it into the third interface. The third interface is connected to the air pump. At this time, start the air pump, and pressurized air enters the flow channel in the water blanket along the outlet pipe, discharging the residual water inside from the drain outlet of the T-joint drain pipe.

[0025] like Figure 1-8 As shown, a residual water removal structure for a water-heated blanket includes a main unit 2 and a water blanket 1. The main unit 2 contains a water pump 22, a water tank 21, a heating element 23, and an air pump 24. The outer casing of the main unit 2 is provided with a first interface 25, a second interface 26, and a third interface 27. The water blanket 1 is provided with a water inlet pipe 11 and a water outlet pipe 12. The main unit is equipped with a warm water circulation mode and a residual water removal mode. In the warm water circulation mode, the water tank 21, water pump 22, heating element 23, first interface 25, water inlet pipe 12, water blanket 1, water outlet pipe 11, second interface 26, and water tank 21 are sequentially connected to form a loop. The water in the water tank is heated and then enters the flow path inside the water blanket 1 through the water inlet pipe 12, making the water blanket 1 warm. At this time, the warm water circulation loop is not connected to the air pump 24. A drainage mechanism is provided in the water inlet pipe 12, which includes a three-way drain pipe 121, a drain outlet protective shell 122, and a three-way pipe cap 123. In the warm water circulation mode, the tee cover 123 blocks the tee drain pipe 121, thus closing its drain outlet.

[0026] The water tank 21 is equipped with a water pump port 212, a return water port 214, and a water inlet 211. A float valve (not shown) is installed on the water inlet. The water pump port 212 is connected to the water pump 22, and the return water port 214 is connected to the second interface 26.

[0027] When the water-heated blanket is in circulating heating mode, the water in the water tank 21 is pumped from the water pump port 212 to the heating element 23 for heating. The heated water is then transported to the water blanket 1 through the first interface 25 and the inlet pipe 12 to heat the blanket, and then flows back to the water tank 21 through the outlet pipe 11, the second interface 26 and the return port 214, thus realizing water circulation between the water tank 21 and the water blanket 1. When the water-heated blanket is draining, the three-way pipe cover 123 is opened to allow most of the water in the water blanket 1 to drain. Then, the outlet pipe 11 is switched from the first interface 25 to the third interface 27, which is connected to the outlet pipe 11. Since most of the water in the water blanket 1 has been drained, splashing is less likely during the switching process. The air pump 24 is then activated to blow air. The air passes through the third interface 27, the outlet pipe 11, the water blanket 1, and the inlet pipe 12, thereby draining the remaining water in the water blanket 1 through the three-way drain pipe 121.

[0028] A cooling fan 28 is installed below the heat-generating element 24 for convenient heat dissipation.

[0029] Both the drain outlet protective cover 122 and the tee pipe cover 123 are made of silicone rubber or are highly malleable plastic products. They are connected by a soft band and can be integrally molded. The tee pipe cover 123 has a first inner hole for sealing the drain outlet of the tee drain pipe. The drain outlet protective cover 122 is provided with a tee pipe outlet 1222 and an axially penetrating containment cavity 1221. The tee pipe outlet 1222 and the containment cavity 1221 are perpendicularly intersected. A sleeve opening 1223 is provided on one side wall. By prying open the sleeve opening 1223, the tee drain pipe can be inserted into the containment cavity towards the tee pipe outlet 1222. The drain outlet section of the tee drain pipe extends out from the tee pipe outlet 1222. The drain outlet protective cover 122 not only wraps around the tee drain pipe to prevent it from separating from the inlet pipe section, but also has the beneficial effect of improving the appearance and product grade.

[0030] Although embodiments of the present invention have been shown and described, those skilled in the art should understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents. Improvements made without inventive effort should be included within the protection scope of the present invention.
