The invention belongs to the technical field of outboard engines, and particularly relates to a waterproof spray pump type outboard engine which comprises an outboard engine assembly and a first pressure-resistant shell, a protection mechanism is arranged at the top of the first pressure-resistant shell, a pulling handle is arranged on the lower side of the protection mechanism, a water pump is arranged on the lower side of the protection mechanism, and the protection mechanism comprises a second pressure-resistant shell. The second pressure-resistant shell is fixedly connected to the top of the first pressure-resistant shell, a cavity is formed in the second pressure-resistant shell, and the pulling handle is hinged to the bottom of the second pressure-resistant shell. According to the waterproof spray pump type outboard engine, through the use of the protection mechanism, when the waterproof spray pump type outboard engine falls into water accidentally and a switch valve of a second ventilation opening is not closed in time, as water continuously enters a cavity, a piston plate slides upwards, and a sleeve is driven to move so that an abutting block can abut against a contact switch. At the moment, the contact switch controls the electromagnetic valve to be opened, compressed gas in the compression bin is sprayed out, gas in the cavity is extruded and exhausted, and therefore the device can float upwards and is prevented from sinking to the bottom and being lost.
本发明属于舷外机技术领域,具体涉及一种防水喷泵型舷外机,包括外机组件与耐压壳一,所述耐压壳一的顶部设置有防护机构,所述防护机构的下侧设置有拉动把手,所述防护机构的下侧设置有水泵,所述防护机构包括耐压壳二,所述耐压壳二固定连接在耐压壳一的顶部,所述耐压壳二的内部开设有空腔,所述拉动把手铰接在耐压壳二的底部。该防水喷泵型舷外机通过防护机构的使用,当该装置意外向水中脱落且通气口二的开关阀未及时关闭时,随着水流持续进入空腔,活塞板会向上滑动,并带动套管移动使抵接块与接触开关相抵接。此时,接触开关控制电磁阀打开,压缩仓中的压缩气体喷出,将空腔中的气体挤压排出,从而使装置能够上浮,避免沉底丢失。
