[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0031] The present utility model provides a fully plastic pump, and its embodiments are as follows Figures 1 to 3 As shown, the fully plastic pump is entirely made of plastic. The fully plastic pump includes a pump housing 10, a pump head 20 installed on the pump housing 10 in a pressable manner, and a pump core 30 disposed inside the pump housing 10.

[0032] Regarding the pump housing 10, as Figure 1 and Figure 2 shown, its outer shape is approximately cylindrical. An inner flanging 11 is provided inside the pump housing 10, and the inner flanging 11 is generally disposed at the middle position inside the pump housing 10, so that the inside of the pump housing 10 is divided into two mutually separated and communicating spaces. At this time, the pump head 20 can be installed in the upper space, and the pump core 30 can pass from the upper space down to the lower space.

[0033] Regarding the pump head 20, as Figure 1 and Figure 2 shown, its outer shape is approximately cylindrical, and a corresponding material guiding channel 21 is provided inside. One end of the material guiding channel 21 is used to connect with the pump core 30 to obtain the input of materials, and the other end of the material guiding channel 21 is disposed on the side wall of the pump head 20 for the output of materials.

[0034] Among them, in order to realize the connection and conduction between the pump head 20 and the pump core 30, in this embodiment, the material guiding channel 21 is directly inserted into the pump core 30 to connect the two; and since the sizes of the material guiding channel 21 and the pump core 30 match, when the pump head 20 is pressed, the pump core 30 can be driven to move synchronously.

[0035] Regarding the pump core 30, as Figure 2 and Figure 3 shown, the pump core 30 in this embodiment includes a tubular spring 31, a tubular piston 32, and a tubular core housing 33; the tubular spring 31 is disposed between the pump head 20 and the tubular core housing 33, and the tubular spring 31 is sleeved outside the tubular piston 32; one end of the tubular piston 32 is connected to the tubular spring 31, and this end of the tubular piston 32 is connected to the feeding end of the pump head 20; the other end of the tubular piston 32 is movably inserted into the tubular core housing 33, so that the tubular piston 32 and the tubular core housing 33 form a piston structure; the tubular core housing 33 is fixedly connected to the pump housing 10, and an elastic membrane one-way valve 331 is provided at the feeding end of the tubular core housing 33.

[0036] Specifically, as Figure 2 and Figure 3As shown, the tubular spring 31 is mainly used to realize the reset after the pump head 20 is pressed. Therefore, to ensure that it can quickly recover after being squeezed, in this embodiment, the upper part of the tubular spring 31 is a tubular structure with a smaller pipe diameter, and the lower part is a tubular structure with a larger pipe diameter. Once the tubular spring 31 is squeezed, the tubular structure with a smaller pipe diameter will move into the tubular structure with a larger pipe diameter. When the external force applied to the tubular spring 31 disappears, the tubular structure with a larger pipe diameter has a stronger deformation recovery ability due to its larger size, so that the tubular spring 31 can be quickly restored to its original state.

[0037] Moreover, to ensure the stable and firm installation position of the tubular spring 31, as Figure 2 and Figure 3 shown, in this embodiment, a circle of core shell flanging 332 is provided on the outer wall of the port of the tubular core shell 33 for the tubular piston 32 to be inserted; and it is set that the pump core 30 further includes a tubular limiting member 34. A circle of limiting flanging 341 is provided on the peripheral wall of one end of the tubular limiting member 34, and the other end of the tubular limiting member 34 is inserted into the tubular core shell 33 so that the limiting flanging 341 abuts against the core shell flanging 332; therefore, after a circle of piston flanging 3211 is provided on the outer peripheral wall of one end of the tubular piston 32, the tubular spring 31 can be clamped between the piston flanging 3211 and the limiting flanging 341, and it is convenient for one end of the tubular piston 32 to pass through the tubular limiting member 34 and be inserted into the tubular core shell 33.

[0038] In addition, to prevent the tubular piston 32 from disengaging during movement, as Figure 2 and Figure 3 shown, in this embodiment, the tubular piston 32 is set to include a first pipe section 321, a second pipe section 322, and a piston outer sleeve 323; one end of the first pipe section 321 is connected and communicated with the pump head 20, and a piston flanging 3211 is provided at this end of the first pipe section 321. The other end of the first pipe section 321 is sleeved outside the second pipe section 322; the second pipe section 322 is sleeved with a piston outer sleeve 323; the piston outer sleeve 323 is in close contact with the inner peripheral wall of the tubular core shell 33, and a tubular limiting member 34 that blocks its movement is provided on the movement track of the piston outer sleeve 323 for piston movement.

[0039] Therefore, when the tubular piston 32 moves in the disengaging direction, once the piston outer sleeve 323 meets the tubular limiting member 34, the end of the piston outer sleeve 323 will abut against the end of the tubular limiting member 34, thus realizing the function of preventing the tubular piston 32 from disengaging.

[0040] Furthermore, to realize the installation and fixation of the piston outer sleeve 323, as Figure 3As shown, in this embodiment, the piston outer sleeve 323 is provided to include a first piston annular wall 3231 and a second piston annular wall 3232; the first piston annular wall 3231 is sleeved outside the second pipe section 322, and one end of the first piston annular wall 3231 is clamped between the inner peripheral wall of the first pipe section 321 and the outer peripheral wall of the second pipe section 322; the second piston annular wall 3232 surrounds the outside of the first piston annular wall 3231, and the second piston annular wall 3232 is in fit contact with the inner peripheral wall of the tubular core shell 33.

[0041] Therefore, under the common clamping of the inner peripheral wall of the first pipe section 321 and the outer peripheral wall of the second pipe section 322, the installation position of the piston outer sleeve 323 is fixed; and to further strengthen the installation firmness of the piston outer sleeve 323, as Figure 3 shown, in this embodiment, a circular groove 3221 is further provided on the peripheral wall of the port of the second pipe section 322 adjacent to the elastic membrane one-way valve 331, and the other end of the first piston annular wall 3231 is inserted into the circular groove 3221, that is, the two ends of the piston outer sleeve 323 are fixed at the same time, so that the installation firmness of the piston outer sleeve 323 is fully guaranteed.

[0042] It should also be pointed out that after adopting the above setting method, a pump head 20 and a core shell flange 332 are respectively provided on the two opposite sides of the shell inner flange 11, and the core shell flange 332 is in contact with the shell inner flange 11 to prevent the pump core 30 from moving out in the direction where the pump head 20 is located; and after adopting this structure, the overall installation method of the all-plastic pump is also changed. For example, the pump core 30 is no longer inserted into the pump shell 10 from top to bottom, but is changed to be inserted into the pump shell 10 from bottom to top. Therefore, when installing, the pump head 20 and the pump core 30 actually move towards each other, which is more convenient for processing and production.

[0043] To sum up, since the whole all-plastic pump is made of plastic, when recycling the all-plastic pump, it is no longer necessary to disassemble and classify the all-plastic pump, and only direct overall recycling treatment is required, which greatly improves the recycling efficiency and effectively solves the problem that the existing pump head 20 cannot be directly recycled as a whole.

[0044] In addition to the above all-plastic pump, the present invention also provides a material storage container, as Figures 1 to 6 shown, including a hose 40 and the above all-plastic pump, and the all-plastic pump is installed at the port of the hose 40; the material storage container further includes a pump cover 50, the pump cover 50 is sleeved outside the all-plastic pump, and the connection between the pump cover 50 and the all-plastic pump is detachable; and a core shell flange 332 is provided on the outer wall of its tubular core shell 33, and a gasket 60 is clamped between the flange and the port of the hose 40, and the gasket 60 is sleeved outside the tubular core shell 33.

[0045] In the material storage container made by adopting this setting method, since the whole is also made of plastic, the whole can also be recycled.

[0046] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
