DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figures 1 to 3As shown, a self-locking and leak-proof all-plastic lotion pump includes a bottle cap 1 and a self-locking component 9. A pressure cap 6 is arranged on the top of the bottle cap 1, and a pressure head 7 is penetrated in the middle of the pressure cap 6. A retaining groove 8 is opened on the outer surface of the pressure head 7. The self-locking component 9 is arranged on the outside of the pressure cap 6, and the self-locking component 9 includes a collar 901, a protruding block 902, a support rod 903, a plug plate 904, a fixing plate 905, a compression spring 906, a guide seat 907 and a ring frame 908. The outer surface of the collar 901 is provided with a protruding block 902, and the top of the collar 901 is connected to the support rod 903 through a rotating shaft, and the other end of the support rod 903 is connected to the plug plate through a rotating shaft. 904, and a fixing plate 905 is fixed on the top of the insert plate 904, a compression spring 906 is connected to the side of the fixing plate 905 away from the pressure head 7, and a ring frame 908 is arranged at the other end of the compression spring 906, the guide seat 907 is arranged in the through groove on the surface of the ring frame 908, the raised blocks 902 are distributed in a circular shape and equidistantly along the outer side of the ring 901, and the ring 901 and the ring frame 908 are arranged coaxially, the bottle cap 1 and the ring frame 908 are fixedly connected, and the ring frame 908 is elastically connected to the fixing plate 905 through the compression spring 906, the insert plate 904 runs through the middle of the guide seat 907, and the retaining groove 8 and the insert plate 904 are arranged in the same number.

[0022] The specific operation is as follows: the pressure head 7 is pressed to make the retaining groove 8 and the plug plate 904 at the same height. At this time, the compression spring 906 releases energy to drive the plug plate 904 to slide in the guide seat 907, causing the angle of the support rod 903 to change, so that the ring 901 rotates about the outside of the pressure cover 6, and the three plug plates 904 are inserted into the corresponding retaining grooves 8 to achieve self-locking, thereby preventing the lotion pump from loosening or leaking during transportation or use.

[0023] like Figure 1 As shown, the bottom of the bottle cap 1 is connected to a piston rod 3, and a one-way ball valve 2 is arranged above the inside of the piston rod 3. The bottom of the piston rod 3 is connected to a storage cylinder 4 through a spring, and a straw 5 is connected to the bottom of the storage cylinder 4. A one-way ball valve 2 is also arranged below the inside of the storage cylinder 4, and two one-way ball valves 2 are arranged.

[0024] The specific operation is as follows: press the pressure head 7, the spring is compressed downward, and the extrusion stops. The piston rod 3 will be lifted up by the spring, and at the same time, the upper outlet is closed by the one-way ball valve 2. The air pressure in the storage cylinder 4 is lower than that outside the storage cylinder 4. The emulsion pushes open the one-way ball valve 2 below and is sucked into the storage cylinder 4, and then enters the piston rod 3 and is squeezed out from the pressure head 7.

[0025] In summary, when the self-locking and leak-proof all-plastic lotion pump is used, the storage tube 4 is filled with air when it is used for the first time, and the pressure head 7 is pressed. Due to the obstruction of the one-way ball valve 2 at the bottom of the storage tube 4, the air in the storage tube 4 can only be discharged upward from the piston rod 3. At this time, the pressure head 7 is released, and the piston rod 3 will be lifted up by the spring. At the same time, the upper outlet is closed by the one-way ball valve 2. The air pressure in the storage tube 4 is lower than that outside the storage tube 4. The lotion pushes the one-way ball valve 2 at the bottom and is sucked into the storage tube 4. Press down again to discharge more air, and rebound to suck the lotion. This process is repeated twice, and the air can be completely discharged, and the lotion is squeezed out from the outlet of the pressure head 7.

[0026] When it is necessary to transport a packaging container with a fully plastic lotion pump sealed at the mouth, the support angle of the support rod 903 on the plug plate 904 can be changed by rubbing the collar 901 with fingers, so that the fixed plate 905 overcomes the rebound of the compression spring 906 and drives the plug plate 904 to slide in the guide seat 907 until the plug plate 904 moves away from the pressure head 7, which is beneficial to the further longitudinal displacement of the pressure head 7. Since there are more than one protruding block 902 on the outer surface of the collar 901, when people rub the collar 901, the friction is increased, which is more labor-saving.

[0027] At this time, the pressure head 7 is pressed to make the retaining groove 8 and the plug plate 904 at the same height, and the finger leaves the ring 901. The energy released by the compression spring 906 drives the plug plate 904 to slide in the guide seat 907, and the supporting angle of the support rod 903 to the ring 901 is changed, causing the ring 901 to rotate outside the pressure cover 6, so that the three plug plates 904 are inserted into the corresponding retaining grooves 8 in turn to achieve self-locking, thereby achieving the effect of limiting the longitudinal displacement of the pressure head 7 and preventing the all-plastic lotion pump from vibrating and loosening during transportation.

[0028] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
