In this embodiment, as shown in fig. 5, two temperature fuses 223 are mounted on the first cover 22 of the water tank 20, the cover 232 is in plug-in fit with the pre-water opening 231, and the cover 232 is configured to exit the pre-water opening 231 under the extrusion of the water vapor in the water tank 20 after both temperature fuses 223 fail. Specifically, the cover 232 may be a silicone plug. One of the two thermal fuses 223 may be set to 65 deg.c and the other may be set to 75 deg.c. When the water temperature in the water tank 20 reaches 65 ℃, the temperature fuse 223 set to 65 ℃ is activated. When the temperature fuse 223 set to 65 c is failed and the temperature of the water in the water tank 20 reaches 75 c, the temperature fuse 223 set to 75 c is activated. When the fuse 223 set at 75 ℃ is also deactivated, the temperature of the water in the water tank 20 increases and the pressure of the water vapor increases, so that the cover 232 is pushed by the large water vapor and exits the pre-water inlet 231, thereby preventing the water tank 20 from exploding. The lid 232 of the present embodiment not only seals the pre-water gap 231 but also functions as a safety valve.

As shown in fig. 7, in this embodiment, in order to improve the damping effect, the following measures are adopted:

The cylinder 374 is sleeved on the water outlet pipe 222 of the water tank and also plays a role in shock absorption.

The other end portion of the shock-absorbing body 371 is bent toward the bottom plate 211 of the water tank 20 so that the water pump 30 can still suck water when the water level of the water tank 20 is low.

The other end of the shock absorption main body 371 and the case bottom plate 211 are separated by a distance or abutted to the case bottom plate 211, the end face of the other end of the shock absorption main body 371 is provided with a recessed portion 375 deviating from the case bottom plate 211, and the recessed portion 375 can prevent the end face of the other end of the shock absorption main body 371 from being adsorbed on the case bottom plate 211.

Example two

Fig. 10 is a perspective view of a main unit 100 of a second water heating blanket according to an embodiment of the present invention. As shown in fig. 10, the host 100 of the present embodiment is slightly different from the host 100 of the first embodiment in terms of functions, and the differences are as follows:

EXAMPLE III

In the embodiment, a new function is added on the basis of the first embodiment. The method comprises the following specific steps:

as shown in fig. 11 and 12, at least two reinforcing ribs 233 are distributed on the inner wall of the second cover 23, and the plurality of reinforcing ribs 233 in the first direction and the plurality of reinforcing ribs 233 in the second direction are staggered to increase the strength of the second cover 23. The first direction and the second direction may be perpendicular.

In the prior art, when water in the water tank 20 freezes in a low-temperature environment, the volume of the water tank will expand by about 31%, and the water tank 20 is easily damaged by expansion. In order to prevent the water tank 20 from freezing, the present embodiment adopts the following measures:

the inner wall of the second cover 23 is convexly provided with a mounting edge 234, and a deformable airbag 25 is sleeved on the mounting edge 234 and forms a cavity with the second cover 23. When the water in the water tank 20 is frozen and expanded, the air bag 25 is compressed, thereby providing a space for the ice to prevent the water tank 20 from being swollen out.

The mounting edge 234 is partially recessed to form a first recessed portion 2341, and correspondingly, the bladder 25 is partially recessed to form a second recessed portion 251, and the first recessed portion 2341 and the second recessed portion 251 are used for avoiding the pre-water opening 231, so as to prevent the process of adding water through the pre-water opening 231 from being affected. The first recessed portion 2341 and the second recessed portion 251 are located on the same straight line, and are opposite to the pre-water gap 231. The end surfaces of the first recessed portion 2341 and the second recessed portion 251 may have circular arc shapes, or may have other shapes.

Example four

fig. 13 is a partial perspective view of the main unit of the four-water heating blanket according to the embodiment of the invention. As shown in fig. 13, the cover 232 is detachably mounted on the pre-water opening 231, the second end cap 13 of the housing 10 is provided with a window 131 opposite to the cover 232, and the window 131 is provided with the flip 132. Ideally, the water tank 20 does not require the user to add water on his or her own. However, considering that the water in the water tank 20 may be slightly lost for a long time, the present embodiment provides the window 131 and the structure of the flip 132, so that a user can open the flip 132 in sequence, remove the cover 232, and add water into the water tank 20 through the pre-water inlet 231 by himself.

Specifically, the window 131 may be a rectangular window, and may also be a window of other shapes. One end of the flip cap 132 is hinged to the second end cap 13. The other end of the flip 132 has a buckle 1321, and the flip 132 is in snap fit with the second end cap 13 through the buckle 1321, so that the flip 132 is convenient to open and close.
