In order to more clearly explain the technical solution of the disclosure, the following will briefly introduce the drawings needed in the implementations. Obviously, the drawings in the following description are only some implementations of the disclosure. For those of ordinary skills in the art, they can also obtain other drawings based on these drawings without paying creative labor.
The drawings are marked as follows:
The technical solution in the implementations of the disclosure will be described clearly and completely in combination with the drawings in the implementations of the disclosure.
The disclosure provides a single material all plastic lotion pump, the embodiments are shown in
When pressing is not carried out, the plastic double piston mechanism 40 is closed, so the communication between the discharge hole 21 and the material guide hose 50 will be cut off, thus the discharge cannot be realized; and after being pressed, the plastic pressing head 20 will move in the direction of the plastic pump casing 10 and control the plastic double piston mechanism 40 to open, so that the discharge hole 21 can communicate with the material guide hose 50 to realize the discharge operation.
In conclusion, because the disclosure is a single material all plastic lotion pump, which includes a plastic pump casing 10, a plastic pressing head 20, a plastic cylinder casing 30 and a plastic double piston mechanism 40, the overall material is plastic, soft rubber, etc., there is no need for disassembly operation in case of recycling, and the full plastic lotion pump can be directly recycled, which greatly improves the recycling efficiency, greatly reduces the recycling cost, and effectively solves the problem of difficult recycling of the existing lotion pump head.
As shown in
When the pressing operation is not carried out, the plastic reset spring 43 will push the first plastic piston 41 to the top of the plastic cylinder casing 30, which is the initial default position of the first plastic piston 41. Similarly, the plastic material guide tube 44 will drive the second plastic piston 42 to move up until the second plastic piston 42 reaches its initial default position; and in this state, the plastic material guide tube 44 is cut off, that is, the all plastic lotion pump cannot output.
After the pressing operation, the plastic material guide tube 44 will drive the first plastic piston 41 and the second plastic piston 42 to move down, and when the second plastic piston 42 moves down to the preset position, the plastic material guide tube 44 and the second plastic piston 42 will move relative to each other, so that the plastic material guide tube 44 will become a state of communication for material delivery, thus realizing the discharge operation of the all plastic lotion pump.
After the pressing operation is canceled, the plastic reset spring 43 will drive the first plastic piston 41 to reset. Under the corresponding linkage action, the second plastic piston 42 will also reset, and the plastic material guide tube 44 will become cut off through the relative movement of the plastic material guide tube 44 and the second plastic piston 42.
In order to realize the communication and blockage control of the plastic double piston mechanism 40, as shown in
As shown in
As shown in
After adopting this setting manner, the spring made of plastic can also have better deformation recovery ability, so that the metal spring can be completely replaced by the plastic reset spring 43.
As shown in
After adopting this setting manner, the installation and fixation of the plastic reset spring 43 are realized. After the plastic reset spring 43 is supported by the bearing step 31, it is ensured that the plastic reset spring 43 can stably drive the first plastic piston 41 and other related components to reset.
As shown in
After adopting this setting manner, the air return hole 32 can be used to realize the pressure difference balance regulation in the plastic cylinder casing 30, so as to ensure that each component can automatically and quickly reset to the original position after the pressing operation.
As shown in
When there is no pressure difference change, the elastic rubber film 62 will completely shield the position of the connection and communication part of the material guide hose 50 and the plastic cylinder casing 30, so the materials will not enter the plastic cylinder casing 30; and after the pressure difference in the plastic cylinder casing 30 is changed due to the pressing operation, the elastic rubber film 62 will deform, thus removing the shielding of the position of the connection and communication of the material guide hose 50 and the plastic cylinder casing 30. Therefore, the materials can enter the plastic cylinder casing 30, so as to realize the one-way input of materials.
As shown in
After adopting this setting manner, the gasket 70 can be used to enhance the tightness of the all plastic lotion pump after assembly in the future.
As shown in
Therefore, when the half ring buckle 80 is buckled, the misoperation on the all plastic lotion pump can be avoided. Only after the half ring buckle 80 is removed, can the normal pressing and discharge operation be realized.
Of course, the above-mentioned all plastic lotion pump will be used in combination with the storage bottle in the actual application process, so the disclosure further provides a single material storage bottle, as shown in
The above is the preferred implementation of the disclosure. It should be pointed out that for those of ordinary skills in the art, certain improvements and embellishments can be made without departing from the principle of the disclosure.
