Abstract
The utility model relates to a move toothpaste dispenser, specifically speaking relates to the automatic toothpaste dispenser's extrusion pump of this kind. It includes the pump body, and the pump body includes the lateral wall of cavity and parcel cavity again, and internal surface towards the outstanding round step of cavity of lateral wall middle part position, the cavity of step top be the upper plenum, and the cavity of step below is cavity down, and upper plenum and cavity axial intercommunication down, upper plenum upwards extend the pump body to be made pump body top surface form one to open the mouth, pump body bottom is equipped with out the cream mouth, goes out cream mouth and lower cavity intercommunication, and lower cavity side wall is the yielding body of elasticity. The utility model has the advantages of reasonable design, through the change to pump body structure, realize pump body lateral wall integrated into one piece, can overcome the inconvenient problem of dismouting, the health is air tight, through to lateral wall gauge control, realizes one section lateral wall intensity height, non -deformable, another section lateral wall is then soft yielding, makes pump body lateral wall accord with functional requirement, and it is more accurate to go out the cream flow control, uses and rinses the convenience.
Description
Technical field
The utility model relates to a kind of automatic toothpaste squeezing device, specifically relates to the extrusion pump of this kind of automatic toothpaste squeezing device.
Background technology
Existing extrusion pump generally includes paste-inletting valve core, wraps up the upper shell of paste-inletting valve core and belong to yielding lower casing, the connector of shell and lower casing in locking, upper shell parcel paste-inletting valve core, can not be out of shape, therefore, upper shell needs higher-strength, and lower casing is because of needs deformable squeeze toothpaste, and therefore lower casing adopts comparatively soft material.So current all extrusion pumps all adopt two sections of Split type structures, the weak point of this structure is apparent, and the dismounting trouble between upper shell, lower casing and connector three, the junction of upper shell and lower casing easily leaks gas, and how unhygienic gap is.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of air tight, health and there is not the extrusion pump of toothpaste dispenser of integral type of dismounting problem.
The purpose of this utility model realizes like this.
A kind of extrusion pump of toothpaste dispenser, comprise the pump housing, the pump housing comprises again the sidewall of cavity and parcel cavity, the inner surface of sidewall medium position is towards the outstanding circle step of cavity, cavity above step is upper plenum, cavity below step is lower cavity, and upper plenum is axially communicated with lower cavity, and upper plenum extends upward the pump housing makes pump housing end face form an open ports.
Described pump housing bottom is provided with paste outlet, paste outlet and lower cavity connects, and lower cavity sidewalls is the variable body of elasticity.
Upper plenum sidewall thickness is greater than lower cavity sidewalls thickness, and step is provided with outstanding collar with the outer surface of the sidewall of radial position.
Technique scheme also can be made to the following further improve.
Also comprise paste-inletting valve core, paste-inletting valve core inserts upper plenum from the open ports of the pump housing, and the inner of paste-inletting valve core and step are mutually against location, and the inner of paste-inletting valve core is provided with send cream mouth, send cream mouth to be communicated with lower cavity,
Described cream mouth and the paste outlet of sending is normally closed port.
Also include packing ring, packing ring is located at the variable body of support elasticity outside paste outlet.
The utility model reasonable in design, by the change to pump body structure, realize pump housing sidewall one-body molded, the inconvenient problem of dismounting can be overcome, health is air tight, by oppose side wall THICKNESS CONTROL, realize one section of side wall strength high, not yielding, another section of sidewall is then soft yielding, make pump housing sidewall meet functional requirement, paste volume controls more accurate, uses easy to clean.
Accompanying drawing explanation
Fig. 1 is the axial decomposing schematic representation of extrusion pump.
Fig. 2 is the axial sectional structure schematic diagram of extrusion pump.
Fig. 3 is that extrusion pump is arranged on structural representation in toothpaste dispenser.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment, composition graphs 1 to Fig. 2, a kind of extrusion pump of toothpaste dispenser, comprise the pump housing 1, paste-inletting valve core 2, the pump housing 1 comprises again cavity and sidewall 4, and the inner surface of sidewall 4 medium position is towards the outstanding circle step 5 of cavity, cavity above step 5 is upper plenum 30, cavity below step 5 is lower cavity 31, and upper plenum 30 is axially communicated with lower cavity 31, and upper plenum 30 extends upward the pump housing 1 makes pump housing end face form an open ports.The described pump housing 1 bottom is provided with paste outlet 7, and paste outlet 7 is communicated with lower cavity 31, and lower cavity 31 sidewall is the variable body 8 of elasticity.
Upper plenum 30 sidewall thickness is greater than lower cavity 31 sidewall thickness, and step 5 is provided with outstanding collar 9 with the outer surface of the sidewall of radial position.Lower cavity 31 sidewall can stress deformation, and upper plenum 30 sidewall then keeps some strength not to be out of shape.
Paste-inletting valve core 2 inserts upper plenum 30 from the open ports of the pump housing, the inner of paste-inletting valve core 2 and step 5 are mutually against location, and the inner of paste-inletting valve core 2 is provided with send cream mouth 6, send cream mouth 6 to be communicated with lower cavity 31, paste-inletting valve mandrel, to also there being an inner chamber 20, send cream mouth 6 to communicate with inner chamber 20.
Described cream mouth 6 and the paste outlet 7 of sending is normally closed port.
Packing ring 10 is had to be located at the variable body 8 of support elasticity outside paste outlet 7.
The use procedure of lower the present embodiment is described below in conjunction with Fig. 3, when stripper plate 11 is subject to the extruding of toothbrush as shown by arrows, stripper plate 11 rotates, the upper end of stripper plate upwardly packing ring 10 simultaneously, packing ring 10 is the variable body 8 of elasticity upwardly, cavity volume in the variable body of elasticity diminishes, pressure increase, paste outlet 7 is opened, extrude toothpaste, cream mouth 6 is sent also to open, once packing ring loses external force, the variable body of elasticity utilizes its own resilient to resile shape, cavity pressure in the variable body of elasticity reduces, the toothpaste of paste-inletting valve in-core enters in the variable body of elasticity by sending cream mouth.
Collar 9 is by clamping with the shell 12 installing the pump housing, and the sidewall at other position of the pump housing is also by shell 12 jam-packed.
