[0006] Furthermore, a second waterproof slot is provided around the button cap, a second waterproof insert ring is provided on the inner side of the face shell, the waterproof insert ring surrounds the button slot, and the second waterproof insert ring cooperates with the second waterproof slot, so as to prevent alcohol or water vapor from entering the shell through the button cap and the face shell, thereby preventing the motherboard and electronic components inside the fetal heart monitor from being damaged.

[0007] Furthermore, the shell is provided with a wire hole, the wire hole is provided with a waterproof groove, one end of the connecting wire is provided with a waterproof platform, and the waterproof groove cooperates with the waterproof platform, so as to prevent alcohol or water vapor from entering the shell through the connecting wire and the shell, thereby preventing the motherboard and electronic components inside the fetal heart monitor from being damaged.

[0008] Furthermore, the highly waterproof Doppler fetal heart rate monitor also includes: a waterproof TYPE-C seat connected to the main board.

[0009] Furthermore, the surface shell and the bottom shell are connected by snap fasteners.

[0010] By adopting the above scheme, the utility model provides a highly waterproof Doppler fetal heart monitor, in which a first waterproof slot is provided on the joint surface of the face shell and a first waterproof insert ring is provided on the joint surface of the bottom shell. When the first waterproof insert ring cooperates with the first waterproof slot, alcohol or water vapor can be fully prevented from entering the shell through the joint between the face shell and the bottom shell; when the second waterproof insert ring cooperates with the second waterproof slot, alcohol or water vapor can be prevented from entering the shell through the key cap and the face shell; the waterproof groove cooperates with the waterproof platform to alcohol or water vapor can be prevented from entering the shell through the connecting line and the shell; therefore, damage to the mainboard and electronic components inside the fetal heart monitor caused by spraying alcohol for disinfection or accidental moisture can be fully prevented.
