Summary of the invention

The purpose of this utility model is the baroque problem that exists in the existing atomizing pump in order to solve, and a kind of atomizing pump simple in structure is provided.

Technological scheme:

The purpose of this utility model is achieved in that a kind of atomizing pump, comprise the pump housing, piston, spring, blind nut, bead, head and diffusion nozzle, wherein the under shed of bead and pump housing inner chamber constitutes the imbibition one-way valve, diffusion nozzle is installed on the head, piston is positioned at pump housing inner chamber, it is characterized in that pump housing upper shed is fixed in the blind nut, the connection handle of piston stretches out outside the pump housing and head is fixed, the axial hole of piston is communicated with pump housing inner chamber and diffusion nozzle, the inboard placement of piston sealed the switch block that piston shaft is taken out the through hole under shed, place described spring between switch block and the pump housing intracavity bottom, switch block top is provided with the post in the axial hole that stretches into piston, the external diameter of this post and the axial hole of piston is slidingly matched and have side channel vertically on the surface of post.Constitute the outlet one-way valve between switch block and the piston axial hole.

Described atomizing pump is characterized in that upper shed place of the described pump housing is fixed with locking closure, and locking closure limits the outermost displacement of piston.

Described atomizing pump is characterized in that clamping between the described locking closure and the pump housing.

Described atomizing pump, it is characterized in that the described blind nut outside is positioned at the center through hole periphery and is provided with the annular wing, this annular wing inwall is provided with the ring lock muscle, and the outer cylinder of pump housing upper shed is provided with annular muscle, and the height of this annular muscle equals the distance of the ring lock muscle of blind nut to the center through hole upper-end surface.When the pump housing is installed, the annular muscle on the pump housing is pressed into blind nut annular wing bottom, up to crossing the ring lock muscle, thereby the pump housing is fixed in the blind nut.

Beneficial effect:

Owing to adopted technological scheme described in the utility model, switch block directly constitutes the outlet one-way valve, and the slip of the axial hole of post on the switch block and piston matches, motion to switch block play the guiding role, simultaneously offer side channel at the outer surface of column of switch block and can allow the liquid of pump housing inner chamber pass through smoothly, it is simple in structure, cost is low.

Embodiment:

Fig. 1 is an embodiment's of an atomizing pump described in the utility model internal structure schematic representation.As can be seen from Fig. 1, described atomizing pump comprises the pump housing 3, piston 7, spring 4, blind nut 6, bead 2, head 10 and diffusion nozzle 11, and diffusion nozzle 11 is installed on the head 10; During installation, can place bead 2, spring 4, switch block 5, piston 7 and locking closure 8 to the inner chamber of the pump housing 3 in order, locking closure 8 is provided with card platform 81 and blocks the hole clipping (not marking among the figure) that matches with it on the pump housing, then the annular muscle on pump housing top and the annular muscle on locking closure 8 tops are pressed in the annular wing of blind nut 6 upsides simultaneously, till the annular muscle locking of the lock muscle 61 on the annular wing with the pump housing and locking closure, again attachment post 9 tightly is inserted in piston 7 tops, to tightly be inserted in attachment post 9 tops with the head 10 of diffusion nozzle 11 again, and suction pipe 1 be inserted the pump housing descend the place to get final product most.
