The utility model provides a double-spring all-plastic vacuum pump, the embodiment of which is shown in figure 1 and figure 2, comprising a base 10 and a press head 20, wherein the bottom of the base 10 is provided with a feed hole 11, the press head 20 and the base 10 are assembled to form a containing cavity 12, the feed hole 11 is communicated with the containing cavity 12, and a limit cover 30, a plastic one-way spring 40, a discharging piece 50 and a plastic reset spring 60 are arranged in the containing cavity 12; the limiting cover 30 surrounds the outside of the feeding hole 11, a guide hole 31 is formed in the top of the limiting cover 30, and the guide hole 31 is communicated with the inside of the limiting cover 30; the plastic one-way spring 40 is clamped between the base 10 and the limiting cover 30, two opposite ends of the plastic one-way spring 40 are respectively a fixed end 41 and a stressed end 42, the fixed end 41 is communicated with the feeding hole 11, and the stressed end 42 is communicated with the guide hole 31; the discharging piece 50 is arranged between the press head 20 and the limiting cover 30, the discharging piece 50 is communicated with the stress end 42 through the guide hole 31, and the discharging piece 50 is used for receiving materials to the press head 20 for output; the plastic return spring 60 is clamped between the discharging piece 50 and the limit cover 30; the pressing of the button 20 is used to push the discharging member 50 to compress the plastic one-way spring 40.
When the double-spring all-plastic vacuum pump is applied, the double-spring all-plastic vacuum pump and the bottle body 70 are assembled for use, the bottle body 70 is fixedly connected with the base 10, and materials are stored in the bottle body 70; if a user presses the button head 20, the discharging piece 50 presses the plastic one-way spring 40 and the plastic return spring 60, so that the plastic one-way spring 40 and the plastic return spring 60 are in a contracted state, and materials in the plastic one-way spring 40 are conveyed to the button head 20 through the discharging piece 50 and are discharged; after the user no longer presses the button 20, the plastic one-way spring 40 will automatically recover, and due to the change of the air pressure, the plastic one-way spring 40 will automatically extract the material from the bottle 70 until the material fills the interior of the plastic one-way spring 40, and the plastic return spring 60 will automatically recover, so as to push the button 20 back to the initial position.
Therefore, the scheme replaces a metal spring with the plastic one-way spring 40 and the plastic return spring 60, and when the pump head is recycled, the pump head can be treated in a unified mode, so that the problem that the existing pump head is inconvenient to recycle directly is solved practically.
As shown in fig. 1, the discharging member 50 includes a discharging pipe 51 and a positioning cover 52; the discharge pipe 51 penetrates through the guide hole 31 to be inserted into the plastic one-way spring 40, a discharge channel 53 is formed in the hollow interior of the discharge pipe 51, and the discharge channel 53 is communicated with the interior of the plastic one-way spring 40; the positioning cap 52 surrounds the outer peripheral side of the end portion of the tapping pipe 51, an annular groove 54 is defined between the positioning cap 52 and the outer wall of the tapping pipe 51, and one end portion of the plastic return spring 60 is fitted into the annular groove 54.
After adopting this structure, the material of the plastic one-way spring 40 can be conveyed to the press head 20 through the discharging channel 53 and discharged, and the annular groove 54 also realizes the fixing of the mounting position of the upper part of the plastic return spring 60, thereby providing a guarantee for the working stability of the plastic return spring 60.

After adopting the structure, the convex ring 32 realizes the fixation of the installation position of the lower part of the plastic return spring 60, thereby further improving the working stability of the plastic return spring 60.
As shown in fig. 1, a connector 80 is further disposed in the accommodating chamber 12, and the connector 80 includes a cover portion 81 and a tube portion 82 connected to each other; the cover body part 81 is arranged in the limit cover 30, the stress end 42 is arranged in the cover body part 81, and the stress end 42 is abutted against the cover body part 81; the body 82 passes through the guide hole 31 to be fitted over the outlet pipe 51.
That is, after the user presses the button 20, the discharging member 50 can drive the connector 80 to move downwards together, so that the connector 80 applies downward pressure to the plastic one-way spring 40, thereby realizing the compression control of the plastic one-way spring 40; and the plastic one-way spring 40 will return the connector 80 together after the user no longer presses the button 20.
As shown in FIG. 1, a limiting wall 83 which narrows inwards is arranged at the inner connection part of the pipe body part 82 and the cover body part 81, a space enclosed by the limiting wall 83 is communicated with the plastic one-way spring 40 and the discharge channel 53, and the minimum diameter of the limiting wall 83 is smaller than the outer diameter of the discharge pipe 51.
Since the stopper wall 83 is formed in a substantially inverted conical shape, when the discharge pipe 51 moves downward, the discharge pipe 51 abuts against the stopper wall 83 to move the connector 80 downward.
As shown in FIG. 1, the tapping pipe 51 comprises a feeding section 511 and a discharging section 512 which are connected with each other, a positioning cover 52 is arranged on the outer wall of the port of the discharging section 512, and the outer diameter of the discharging section 512 is larger than the inner diameter of the pipe body part 82.
That is, as the discharging pipe 51 moves down, the discharging portion 512 will abut against the pipe body 82, thereby limiting the discharging pipe 51 from moving down continuously, and avoiding the phenomenon that the discharging pipe cannot be reset due to excessive downward movement.
As shown in fig. 1, a supporting ring 90 is provided in the cover 81, the supporting ring 90 is embedded in the force-receiving end 42, and the force-receiving end 42 is clamped in a space defined by the supporting ring 90 and the cover 81.
Because the space that the supporting ring 90 and the cover body part 81 enclose is less, so both can realize stable centre gripping to plastics one-way spring 40, avoid plastics one-way spring 40 to produce unstable deformation to it resets to provide the guarantee to stabilize the compression for plastics one-way spring 40.
As shown in fig. 1, the inner surface of the bottom of the base 10 is provided with a first annular positioning groove 131, the first annular positioning groove 131 surrounds the feeding hole 11, and the fixed end 41 is embedded in the first annular positioning groove 131; the inner surface of the bottom of the base 10 is further provided with a second annular positioning groove 132, the second annular positioning groove 132 surrounds the first annular positioning groove 131, and the lower part of the limiting cover 30 is embedded into the second annular positioning groove 132; after the mode is adopted, the installation stability of the plastic one-way spring 40 and the limit cover 30 can be improved.
As shown in FIG. 1, the dual-spring all-plastic vacuum pump further comprises a housing 100, wherein the housing 100 is detachably sleeved outside the button 20; that is, when the device is needed, the outer cover 100 can be removed, and when the device is not needed, the device can be covered with the outer cover 100 for protection, so that the materials are prevented from being oxidized.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
