Specific embodiment
Hereinafter embodiment of the present utility model is illustrated by particular specific embodiment, those skilled in the art can be by this
Content disclosed by description understands other advantages of the present utility model and effect easily.
Embodiment
Front and back position described in the utility model, the one end being connected with power mobile phone when being and being used with medical driving means is front
Side, thus joint is front, motor cabinet is rear.
As shown in Fig. 2 a kind of medical driving means of anti-imbibition, including joint 2, motor cabinet 1 and cooling fan 4, wherein
Joint 2 is used for being connected with power mobile phone, and motor cabinet 1 is threadeded with joint 2 rear end, is provided with motor 3, motor in motor cabinet 1
Seat 1 afterbody is additionally provided with air inlet, and wherein, cooling fan 4 is arranged on the output shaft 10 of motor 3 front end, and this cooling fan 4 is located at
In joint 2 rear portion, joint 2 rear portion is provided with thermovent 6 near the position of cooling fan 4, and thermovent 6 is with cooling fan 4 at least
Partly relatively, it is critical only that：It is provided with wind shielding structure between the leading portion passage 11 of cooling fan 4 and joint 2, this knot that keeps out the wind
Structure is located on front side of thermovent 6.Medical driving means shown in contrast Fig. 1, have larger suction force in original joint 2, lead to art
Middle passiveness imbibition.After setting wind shielding structure, motor 3 rotates and drives the negative pressure that cooling fan 4 produces when rotating to be hidden by wind shielding structure
The no big suction force in, joint 2 of block, is not enough to form the situation of passiveness imbibition joint 2 in, thus avoid imbibition showing
As it is ensured that the service life of power mobile phone and motor 3.
In this example, wind shielding structure is annular deep bead 7, and this deep bead 7 is arranged on cooling fan 4 front end, deep bead 7 with
Joint 2 inwall has gap in radial direction, and deep bead 7 blocks cooling fan 4 front end, thus in cooling fan 4 work process, gear
Live the suction air of cooling fan 4 generation so as to be not enough to be formed larger suction force in joint 2, simultaneously can be by radiating
Mouth 6 outside air discharging and radiatings.Certainly, in other embodiment, deep bead 7 can be arranged on joint 2 inwall, equally can solve to inhale
The problem of liquid.
Further, as shown in Figure 4 and Figure 5, in order to save processing cost and to the use reprocessing inventory part, cool down wind
Fan 4 is integrally formed with bar 8 of passing on Gong, and deep bead 7 is enclosed within outside drive link 8, and is welded on flabellum end face and the drive link of cooling fan 4
On 8.On the one hand simplify mounting structure, on the other hand reduce the change to existing product, beneficial to saving production cost.Certainly keep out the wind
Plate 7 can also be with cooling fan 4 and the integrally manufactured molding of drive link 8.
Further as shown in figure 3, forming certain normal pressure for the ease of in installation and work process in joint 2, prevent
The only generation of suction force, staggered with thermovent 6 in cooling fan 4 front portion, that is, cooling fan 4 front end exceedes forward thermovent 6, then
Portion is relative with thermovent 6, so that thermovent 6 is equipped with range difference a apart from fan deep bead 7 installation position；Simultaneously in thermovent 6
On joint 2 inwall of front side, setting one circle keeps out the wind step 9, and the step 9 that keeps out the wind is located on rear side of deep bead 7, and keep out the wind step 9 inner circle with
There is between deep bead 7 is cylindrical gap b.When cooling fan 4 rotates, because deep bead 7 has blocked entering of joint 2 interior air-flow
Enter, air-flow enters from the corresponding air inlet 5 of motor 3 afterbody, takes away motor 3 heat, to thermovent 6 under cooling fan 4 effect
Discharge；Meanwhile, the air-flow that cooling fan 4 produces is blown into the gap b that step 9 is with deep bead 7 side that keeps out the wind, before making joint 2
Certain malleation is produced in Duan Tongdao 11.Because deep bead 7 has blocked the entrance of most of air-flow in joint 2, gas backward on a small quantity
Stream is offseted with the malleation producing the b of gap at so that air balance in joint 2 is it is therefore prevented that passiveness imbibition phenomenon in performing the operation
Produce.
In this example, threadeded with motor cabinet 1 in joint 2 rear end, and this joint 2 is pre-small post-large ladder tubular construction, described
Cooling fan 4 is located in joint 2 big footpath section, and the drive link 8 of cooling fan 4 front end stretches in joint 2 path section.Thermovent 6 is opened
It is located in joint 2 big footpath section, on front side of motor 3.Wherein due to the working condition of motor 3 rotating, consider using from
Core type fan.The junction of joint 2 big footpath section and path section forms the shoulder (i.e. end difference) of joint, and wind shielding structure is located at cooling
Between fan 4 and shoulder.Between in other embodiment, wind shielding structure can be fixed on drive link 8, and cooling fan 4 front end has
Every；Wind shielding structure can also be fixed on the section inwall of big footpath, but will avoid producing interference with drive link 8.
During motor 3 work, motor 3 drives cooling fan 4 to rotate, and cooling fan 4 aspirates wind-force from motor 3 afterbody, takes away
The heat that motor 3 work distributes, discharges from thermovent 6, cooling fan 4 front end is due to the effect of deep bead 7, and thermovent
6 with the range difference of cooling fan 4, form certain malleation in cooling fan 4 near joint 2 one end, preferably improve joint 2
The passive suction force at end, is not enough to form the situation of passive imbibition in joint 2.Joint 2 of the present utility model is inserted in water,
Verify after tested, original medical power set have rapidly water to fly out from thermovent 6, this utility model is anhydrous to fly out from thermovent 6.
Any person skilled in the art all can be without prejudice under spirit and the scope of the present utility model, to above-described embodiment
Carry out modifications and changes.Therefore, such as those of ordinary skill in the art without departing from disclosed in this utility model
Spirit and technological thought under all equivalent modifications of being completed or change, must be contained by claim of the present utility model
Lid.
