Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.
The first embodiment is as follows:
as shown in fig. 1-3, in the connection structure of the motor and the valve block of the present embodiment, the motor 1 includes a housing 11 and a motor shaft 12; the valve block 2 comprises a through hole 21 for the motor shaft 12 to pass through; the motor shaft 12 includes a motor shaft 121 and a limiting portion 122 formed at one end of the motor shaft 121 close to the housing 11; correspondingly, one end of the valve block 2 close to the casing 11 is recessed outwards to form a mounting groove 22 matched with the limiting part 122, and the mounting groove 22 is provided with the through hole 21.
