the heating device 100 comprises a water pump assembly, the water pump assembly abuts against the convex wall part 139, the water pump assembly comprises a water pump fixing part and a water pump, the water pump fixing part fixes the water pump and the first support 13, and the water pump assembly abuts against the arc-shaped part 1391;

protruding wall portion 139 has first spacing 1392 and second spacing 1393, and arc 1391 both sides are located to first spacing 1392 and second spacing 1393 branch, and the water pump assembly sets up with first spacing 1392, second spacing 1393 are fixed.

The installation position of the water pump assembly is arranged on the first support 13, so that the heating device can be integrated with the water pump assembly, and the structure is more compact and small.

Specifically, first spacing 1392 is with the form of buckle, and second spacing 1393 is with the form of fixed column, the water pump mounting is with the staple bolt form, the one end of staple bolt with the spacing setting of first spacing 1392, the other end of staple bolt passes through the fix with screw with second spacing 1393. So, when fixed with water pump and first support, the accessible blocks first spacing 1392 with the one end of water pump mounting, and the other end passes through the thread tightening with spacing 1393 of second, easy operation, and with water pump integration in first support, compact structure.

As another embodiment, the first and second limiting portions may be in the form of fixing posts, so that the water pump and the first bracket may be integrated by fixing the two ends of the water pump fixing member to the first and second limiting portions respectively, for example, by threads.

It should be noted that: the above embodiments are only used for illustrating the present invention and not for limiting the technical solutions described in the present invention, such as the definition of the directionality of "front", "back", "left", "right", "up", "down", etc., although the present specification has described the present invention in detail with reference to the above embodiments, it should be understood by those skilled in the art that the technical solutions and modifications can be combined with each other, modified or replaced with equivalents by those skilled in the art, and all the technical solutions and modifications that do not depart from the spirit and scope of the present invention should be covered by the scope of the claims of the present invention.
