Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
The utility model discloses a kind of cosmetics pump head external spring drawing liquid pumps, as shown in Figure 1, including pressing bar 1, bullet
Spring 2, retainer ring 3, piston 4, bottom valve 5, pump case 6 and check valve 7, are embedded among retainer ring 3 by bar 1, and are pressed inside bar 1 up and down
Setting, the setting of piston 4 is by 1 lower end of bar, and bottom valve 5 is set in 4 lower end of piston, and 5 inner hollow of bottom valve is simultaneously provided with connecting chamber
It is connected with by 1 chamber of bar, rigid member is connected to become by annular groove and 5 ring buckle of bottom valve by bar 1.Pump case 6 is arranged in retainer ring 3
Outside, 3 outer wall of retainer ring are provided with ring buckle 8, and 6 inner wall of pump case is correspondingly arranged on annular groove 9, as shown in fig. 7, retainer ring 3 passes through ring
Shape button 8 is fixedly connected with 6 inner wall annular groove 9 of pump case.6 lower end of pump case is internally provided with check valve 7, check valve 7 by end face with
The ring buckle of pump case 6, which cooperates, to be fixed, and 7 spherical surface of check valve is close to generate sealing with 6 annular surface of pump case by three supporting ribs.Bottom valve
Form chamber between 5 and pump case 6 and check valve 7, spring 2 is set in by outside 1 upper end of bar, and 2 both ends of spring be against respectively by
On bar 1 and retainer ring 3, the frictional force between 6 inner wall of piston 4 and pump case is greater than piston 4 and by the frictional force between 1 inner wall of bar.Bullet
Spring 2 is installed between the plane of retainer ring 3 and the plane by bar 1, and piston 4 is installed in by between bar 1 and bottom valve 5, in spring 2
Active force under, the anchor ring of piston 4 and the annular surface of bottom valve 5 are adjacent to sealing.The annular surface and 6 inner wall of pump case of piston 4 design
Position interference fit starts sealing function between each other.The annular surface of piston 4 mutually rises with by 1 inner wall of bar design position interference fit
Sealing function.
Working principle:
Working condition 1: when starting to be depressed by bar 1, due to the friction between 6 inner wall of 4 annulus of piston and pump case
Power is greater than 4 annular surface of piston and by frictional force between 1 inner wall of bar, therefore 4 temporal persistence of piston is not subjected to displacement in home position,
Mutual alignment relation between each components of drawing liquid pump is illustrated in fig. 2 shown below, at this time the anchor ring of state lower piston 4 and bottom valve 5
Annular surface separation, generates gap between each other.
Working condition 2: when continuing to be pressed down by bar 1, in the effect due to check valve 7, cavity a10 inner air is successively
By gap between the anchor ring of piston 4 and the annular surface of bottom valve 5, cavity b11, cavity c12 are discharged drawing liquid by 1 aperture of bar
Pump, the positional relationship between each components is illustrated in fig. 3 shown below at this time.
Working condition 3: when be applied to be released by the pressure on bar 1 after, under the active force of spring 2, by bar 1 and bottom valve
5 begin to move up, since the frictional force between 6 inner wall of 4 anchor ring of piston and pump case is greater than 4 annular surface of piston and presses in bar 1
Frictional force between wall, therefore 4 temporal persistence of piston is not subjected to displacement in home position, bottom valve 5 is in the process kind moved up, ring
Shape kept man of a noblewoman is first adjacent to sealing with the anchor ring of piston 4, and the positional relationship between each components is illustrated in fig. 4 shown below at this time.
Working condition 4: as it can be seen in figures 5 and 6, when continuing that bottom valve 5 is driven to move up under the active force of spring 2 by bar 1
Then, piston 4 is moved up by the annular surface promotion of bottom valve 5, negative pressure is generated in cavity d13,7 spherical surface of check valve is negative at this time
It is separated under the action of pressure with 6 annular surface of pump case and generates gap, cosmetics Material also passes sequentially through channel under the action of negative pressure, single
Enter cavity d13 to the gap between 6 annular surface of 7 spherical surface of valve and pump case.When pressing pressing lever 1 again, cosmetics Material
Gap between the anchor ring of piston 4 and the annular surface of bottom valve 5 is passed sequentially through, cavity e14, cavity f 15 are discharged pumping by 1 aperture of bar
Liquid pump, it is for people to use to achieve the purpose that.It is designed by this kind of structure, cosmetics Material is in entire drawing liquid pump working condition
In, it will not be in contact always with the spring 2 of metal product, to avoid cosmetics Material from source because of 2 product of spring
It gets rusty and contaminated possibility, has ensured the safety in utilization of product.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
