Abstract
The utility model belongs to the technical field of the electron, concretely relates to waterproof charger. A waterproof charger, includes casing and built -in circuit board, fan, the casing includes upper cover and inferior valve, its characterized in that: the air intake of upper cover, inferior valve end and air outlet end are equallyd divide and do not are equipped with the capillary groove, be equipped with the wind hole on the capillary groove outer panel, the capillary groove interior plate is the waterproof board, the capillary groove interior plate middle part of air outlet end is equipped with the hole that matches with the fan, the wind channel has been offered at the capillary groove interior plate middle part of air intake end. The utility model discloses set up the capillary groove, even sleet wafts into in the casing, also can stay the capillary groove in, later discharge in the hole with the wind, the damage of can not intaking of internal circuit board.
Description
Technical field
The utility model belongs to electronic technology field, is specifically related to a kind of water proof type charger.
Background technology
Along with the development of electronic technology and the requirement of social enviroment protection, electric vehicle application is increasingly extensive, and as electric bicycle, electric automobile, electronic bus etc., charger demand supporting is with it also increasing.The charger of electric bicycle generally will carry with car, needs to adapt to various environment, but existing charger for electric bicycle water proofing property is not high, when sleety weather uses as easy as rolling off a log because of water inlet cause circuit board damage.
Summary of the invention
For overcoming above-mentioned shortcoming, the utility model proposes a kind of water proof type charger, there is good water proofing property.
The utility model is by the following technical solutions:
A kind of water proof type charger, comprise housing and internal circuit board, fan, described housing comprises upper cover and lower casing, the air inlet end of described upper cover, lower casing and air opening end are provided with capillary groove respectively, described capillary groove outer panel is provided with air holes, described capillary groove interior plate is splash guard, is provided with the hole mated with fan in the middle part of the capillary groove interior plate of described air opening end, offers air channel in the middle part of the capillary groove interior plate of described air inlet end.
Further, described capillary groove is rectangle, circular arc, ship shape.
Further, described air holes is located at the two ends of capillary groove outer panel.
Compared with prior art, advantage of the present utility model and good effect are:
1, arrange capillary groove, even if sleet wafts in housing, also can stay in capillary groove, discharge afterwards with air holes, internal circuit board can not waterlogged damage;
2, adopt ship shape capillary groove, and air holes is located at outer panel two ends, sleet by wind can be discharged along side plate two ends, further increases water proofing property.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model lower casing;
Fig. 2 is the structural representation of the utility model upper cover.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of water proof type charger, comprise housing and internal circuit board, fan (not shown), described housing comprises upper cover and lower casing.
Upper cover as shown in Figure 2, air inlet end and air opening end are provided with ship shape capillary groove respectively, described capillary groove outer panel 2 is provided with air holes 1, described capillary groove interior plate is splash guard, be provided with the hole 4 mated with fan in the middle part of the capillary groove interior plate 31 of described air opening end, in the middle part of the capillary groove interior plate 32 of described air inlet end, offer air channel 5.
Lower casing as shown in Figure 1, air inlet end and air opening end are provided with ship shape capillary groove respectively, described capillary groove outer panel 2 is provided with air holes 1, described capillary groove interior plate is splash guard, be provided with the hole 4 mated with fan in the middle part of the capillary groove interior plate 31 of described air opening end, in the middle part of the capillary groove interior plate 32 of described air inlet end, offer air channel 5.
Lower casing and upper cover close, and internal circuit board and fan, just constitute charger.
During charging, open fan and cause air to flow, wind flows into from air inlet end air holes 1, flows through circuit board through air channel 5, through the hole 4 mated with fan, flows out, play heat radiation object finally by air opening end air holes 1.Sleety weather, sleet wafts into housing, is blocked in capillary groove short stay through capillary groove interior plate, presses to capillary groove outer panel immediately, flow out through air holes under the air driven of flowing.So just largely avoid water and enter enclosure interior damage circuit board.
Adopt ship shape capillary groove, formation buffering area, capillary groove two ends, water flows out more smooth and easy, and compared with rectangle, circular arc capillary groove, waterproof effect is better.
The above; only preferred embodiment of the present utility model; it is not restriction the utility model being made to other form; as long as any those skilled in the art of being familiar with can utilize the technology of above-mentioned announcement to be changed improvement. be do not depart from technical solutions of the utility model content, according to the utility model technical spirit to any simple modification implementing above to do. still belong to the protection range of technical solutions of the utility model.
Claims (3)
