As shown in Figure 3, the space that partition wall 16 will be gone up between barrier film 4, lower diaphragm plate 9 and the pump housing 1 is divided into forward chamber 18 and back side chamber 19, and wherein vibrating mechanism 12 is installed in the back side chamber 19, makes structure compact especially thus.
As shown in Figure 1, partition wall 17 is divided into anterior left chamber 18A and anterior right chamber 18B with forward chamber 18.Loam cake 3 is installed on the pump housing 1 on last barrier film 4, and lower cover 7 is being installed under the lower diaphragm plate 9 on the pump housing 1, is forming inner room 23 between loam cake 3 and the last barrier film 4 thus, and under forming between lower cover 7 and the lower diaphragm plate 9 inner room 24.
Shown in Fig. 1 is further, last barrier film 4 with anterior left chamber 18A and the corresponding position of anterior right chamber 18B on be separately installed with upper valve base 5, be separately installed with on the upper valve base 5 near the one-way valve 2 of fluid input 20 with near the one-way valve 6 of fluid output 21.Equally, lower diaphragm plate 9 with anterior left chamber 18A and the corresponding position of anterior right chamber 18B on be separately installed with lower valve base 5 ', be separately installed with on the lower valve base 5 ' near the one-way valve 8 of fluid output 21 with near the one-way valve 10 of fluid input 20.One-way valve 2 can only be opened on the direction that makes progress, and one-way valve 6 can only be opened on downward direction.One-way valve 8 can only be opened on the direction that makes progress, and one-way valve 10 can only be opened on downward direction.
Below with reference to Fig. 3 vibrating mechanism of the present utility model is described.As shown in Figure 3, the end cap 22 that passes on the pump housing wall that is installed to pump of the motor shaft 14 of motor 15 links to each other with vibrating mechanism 12.In the present embodiment, vibrating mechanism 12 comprises cam 13, and cam 13 is driven by the motor shaft 14 of motor 15.Vibrating mechanism 12 also comprises a center link rod, and cam 13 acts on the upper and lower end of this center link rod.Because the upper end of center link rod 12 is connected with last barrier film 4, the lower end of center link rod 12 is connected with lower diaphragm plate 9, and make going up barrier film 4 and lower diaphragm plate 9 thus can the vibration together via the rotation of the rotation of the motor shaft 14 of motor 15, cam 13 and pumping of center link rod 12.Will appreciate that, vibrating mechanism of the present utility model is not limited to the vibration up and down reciprocatingly that is used for realizing barrier film of cam 13 and center link rod, the vibration up and down reciprocatingly of barrier film also can realize multiple vibrating mechanisms such as piston, crank, connecting rod for example by any mechanism that those of ordinary skill in the art is susceptible to.
Describe the operating process of diaphragm pump of the present utility model below in detail.
As mentioned above, when the motor shaft 14 of motor 15 rotated, cam 13 rotated.The rotation of cam 13 drives center link rod 12 and pumps, and makes thus to go up barrier film 4 and lower diaphragm plate 9 whole up-down vibration.
When last barrier film 4 and lower diaphragm plate 9 vibration downwards, as shown in Figure 1, the downward vibration of last barrier film 4 causes the volume of inner room 23 to increase, form suction force thus, force one-way valve 2 to be opened, the water of fluid input 20 enters inner room 23 via left chamber 18A, and one-way valve 6 since its open direction and one-way valve 2 mutually on the contrary maintenance close.Simultaneously, the downward vibration of lower diaphragm plate 9 causes down the volume of inner room 24 to reduce, form extruding force upwards thus, force one-way valve 8 to be opened, water in the following inner room 24 flows out from the one-way valve of opening 8 thus, and discharge from fluid output 21 via left chamber 18B, and one-way valve 10 since its open direction and one-way valve 8 mutually on the contrary maintenance close.
When last barrier film 4 and lower diaphragm plate 9 upwards vibrate, as shown in Figure 2, the upwards vibration of last barrier film 4 causes the volume of inner room 23 to reduce, form extruding force thus, force one-way valve 6 to be opened, water in the last inner room 23 enters left chamber 18B, and discharges via fluid output 21, and one-way valve 2 since its open direction and one-way valve 6 mutually on the contrary maintenance close.Simultaneously, the upwards vibration of lower diaphragm plate 9 causes down the volume of inner room 24 to increase, and forms suction force thus, forces one-way valve 10 to be opened, the water of fluid input 20 enters down inner room 24 via left chamber 18A, and one-way valve 8 since its open direction and one-way valve 10 mutually on the contrary maintenance close.
Along with the continuous up-down vibration of last lower diaphragm plate 4 and 9, cause water to suck from fluid input 20 continuously, via inner room 23,24 up and down, discharge respectively from fluid output 21.
Owing to adopted two barrier films up and down, the feasible efficient of drawing water of diaphragm pump of the present utility model obviously increases.Owing in the pump housing, be separated into former and later two chambers, in back side chamber, adopt unique vibrating mechanism in addition, made barrier film pump structure of the present utility model compact more.
The diaphragm pump life-span of the present utility model is long, makes the life-span of pump reach more than 800 hours, is 2-4 times of gear pump.In addition, pump stability in running is high, noise is little, directly draws water, and speed is fast, sealing does not require to the water bottle in the underneath type water bottle machine that adopts this diaphragm pump, simple to operate and can dally the long period, to lack of water judge and the situation of anhydrous dry combustion method under can adopt the mode of accumulated time, saving is drawn water and is controlled cost, make the total price of underneath type water bottle machine reduce, increase competitiveness of product.
The specific descriptions of in conjunction with the accompanying drawings the utility model being carried out above it should be appreciated by those skilled in the art that only are exemplary, are used for explaining the utility model, rather than limit protection domain of the present utility model.Those skilled in the art can make various modification and improvement to the utility model according to above-mentioned instruction, for example, the feature in the different mode of executions are made up, and these modification and improvement fall into protection domain of the present utility model.Protection domain of the present utility model is defined by the claims.
