Description

Technical Field

[0001] The invention belongs to the technical field of design of a lifting pump head and a packaging bottle thereof, in particular to a lifting pump head and a packaging bottle thereof. Background Art

[0002] In the packaging of daily chemical pump heads, push-type and pull-type pump head structures are often used. Their working principle is the same as that of a piston water pump. The air in the liquid removal barrel is closed and discharged by using the movement of the piston and the opening of the single-phase valve to create a pressure difference between the inside and outside, so that the liquid rises under the action of atmospheric pressure and is finally discharged from the liquid outlet pipe.

[0003] The existing pull-type pump heads and push-type pump heads can ensure the normal outflow of common liquids in daily use. However, when encountering relatively viscous or easily solidified liquids, the liquids are likely to solidify inside the pump head, rendering the pump head unusable. At this time, the user needs to manually shake the pump head or inject water into the packaging bottle to dilute the solution, which is inconvenient to operate and affects use.

During the process, every time the lifting head 2 is lifted, the lock core 3 located at the top of the lifting head 2 will be pulled synchronously. At this time, the liquid composed of the lifting head 2, the lifting tube 6 and the liquid collection tube 7 The body channel is in a sealed state. With the lifting of the lifting head 2, the space between the sealing plug 9 and the liquid collection tube 7 will expand, and the air pressure in the space will decrease. After the air pressure decreases, the liquid inside the liquid storage bottle 4 will enter the liquid collection tube 7 through the plastic hose 8. Whenever the pulling is completed, the reset spring 5 arranged inside the liquid outlet tube 1 and fixedly connected between the lifting head 2 and the threaded cap 19 can reset the lifting head 2 by its own elastic force. When the lifting head 2 is reset, the space between the liquid collection tube 7 and the sealing plug 9 will be reduced, and the glass ball 11 will be reset synchronously under the action of air pressure.

The plurality of sliding balls 14 are set corresponding to the size of the limiting groove, and the plurality of sliding balls 14 are arranged in a circular array distribution; a filling block 15 is arranged between the plurality of sliding balls 14; during operation, whenever the stirring wheel 10 rotates under the action of the screw 13, the plurality of sliding balls 14 arranged inside the limiting groove can convert the sliding friction between the components into rolling friction by themselves, thereby reducing the friction coefficient, wherein the filling block 15 arranged between the plurality of sliding balls 14 can limit the position of the plurality of sliding balls 14 by themselves, prevent the sliding balls 14 from gathering, and prevent the stirring wheel 10 from falling off from the bottom of the lifting tube 6; this step reduces the friction coefficient between the components, alleviates the wear between the components, and improves the smoothness between the components by setting the sliding balls 14, and limits the relative positions of the plurality of sliding balls 14 by setting the filling blocks 15, which is beneficial to prevent the stirring wheel 10 from falling off, thereby improving the stability and durability of the lifting pump head, extending the service life, and maintaining functional stability.

[0027] like Figure 4 As shown, a fixing block is fixedly connected to the side wall of the stirring rod 16, and the bottom of the fixing block is fixedly connected to the top of the stirring wheel 10; stirring blades 17 are fixedly connected to the side walls of multiple stirring rods 16; when working, the fixing block fixedly connected between the stirring rod 16 and the stirring wheel 10 increases the contact area between the stirring rod 16 and the stirring wheel 10 by itself, and the stirring blades 17 fixedly connected to the side walls of the multiple stirring rods 16 increase the contact area between the stirring rod 16 and the liquid by itself; this step maintains the stability of the stirring rod 16 by setting the fixing block, improves the component structural strength of the pull-type pump head, and increases the contact area between the stirring rod 16 and the liquid by setting the stirring blades 17, which is beneficial to improving the stirring effect.

[0028] like Figure 2 As shown, a liquid collecting plate 22 is fixedly connected to the inner wall of the liquid storage bottle 4, and the liquid collecting plate 22 is set corresponding to the size and position of the plastic hose 8; when working, whenever the liquid inside the liquid storage bottle 4 is exhausted, the liquid collecting plate 22 fixedly connected to the liquid storage bottle 4 can collect the liquid at the bottom of the plastic hose 8 by itself; this step collects the liquid in the liquid storage bottle 4 by setting the liquid collecting plate 22, which is helpful to solve the problem of difficulty in discharging the liquid when the liquid is exhausted, improves the practicality of the packaging bottle, and helps to reduce waste.

[0029] like Figure 1 and Figure 2As shown, a rubber suction cup 18 is fixedly connected to the bottom of the liquid storage bottle 4, and the rubber suction cup 18 is set corresponding to the size of the liquid storage bottle 4; when working, the user can use the rubber suction cup 18 to fix the liquid storage bottle 4 on the surface of a medium such as ceramics and glass, thereby maintaining the stability of the liquid storage bottle 4 and the lifting pump head; this step provides convenience for the user's daily use by setting a rubber suction cup 18 at the bottom of the liquid storage bottle 4 to fix the liquid storage bottle 4 and the lifting pump head, which is beneficial to avoid displacement of the liquid storage bottle 4 during the lifting process, and improves the stability and practicality of the packaging bottle.

[0030] like Figure 4 As shown, a limit block 21 is fixed to the bottom of the lifting tube 6, and a plurality of limit blocks 21 are distributed in a circular array; during operation, whenever the lifting tube 6 moves to the bottom, the plurality of limit blocks 21 fixed to the bottom of the lifting tube 6 will first come into contact with the liquid accumulation tube 7, and after the plurality of limit blocks 21 come into contact with the liquid accumulation tube 7, the lifting tube 6 and the components connected to the lifting tube 6 will maintain the distance between themselves and the liquid accumulation tube 7; this step limits the movement range of the lifting tube 6 and the components connected to the lifting tube 6 by setting a plurality of limit blocks 21, thereby reducing the collision between the lifting tube 6 and the inner wall of the liquid accumulation tube 7, which is beneficial to improving the stability of the lifting pump head and extending its service life.

[0031] like Figure 3 As shown, a sealing sheet 20 is fixedly connected to the inside of the threaded cap 19, and the sealing sheet 20 is set to correspond to the size of the threaded cap 19 and the liquid storage bottle 4; when working, the sealing sheet 20 can seal the threaded cap 19 and the liquid storage bottle 4 by deforming under its own force. During the process, every time the user tightens the threaded cap 19 on the top of the liquid storage bottle 4, the top of the liquid storage bottle 4 will squeeze the sealing sheet 20 fixed to the bottom of the threaded cap 19; this step improves the sealing performance of the connection between the pump head and the packaging bottle by setting the sealing sheet 20 to seal the threaded cap 19 and the liquid storage bottle 4, which is beneficial to avoid liquid leakage and enhances practicality.

[0032] like Figure 2 As shown, a support block 23 is provided at the bottom of the liquid collecting plate 22, and the lifting head 2 is fixedly connected to the bottom of the liquid storage bottle 4; when working, the support block 23 fixedly connected between the liquid storage bottle 4 and the liquid collecting plate 22 can provide support for the liquid collecting plate 22 by itself; this step improves the stability of the liquid collecting plate 22 by providing the support block 23 to support the liquid collecting plate 22, which is beneficial to reduce the deformation of the liquid collecting plate 22 under the action of liquid pressure and pump head suction.

[0033] During operation, whenever the user lifts the lifting head 2, the stirring wheel 10 and the stirring rod 16 arranged inside the lifting pump head can stir the liquid by rotation. During the process, whenever the lifting head 2 is pulled, the lock core 3 located on the top of the lifting head 2 will be pulled synchronously. At this time, the liquid channel composed of the lifting head 2, the lifting tube 6, and the liquid accumulation tube 7 is in a sealed state. As the lifting of the lifting head 2, the space between the sealing plug 9 and the liquid accumulation tube 7 will expand, and the air pressure in the space will decrease. After the air pressure is reduced, the liquid inside the liquid storage bottle 4 will enter the liquid accumulation tube 7 through the plastic hose 8. Whenever the lifting is completed, the return spring 5 arranged inside the liquid outlet tube 1 and fixedly connected between the lifting head 2 and the threaded cap 19 can be elastically released by itself. The lifting head 2 is reset by force. When the lifting head 2 is reset, the space between the liquid collection tube 7 and the sealing plug 9 will be reduced, and the glass ball 11 will be reset synchronously under the action of air pressure. With the reduction of space and the increase of internal pressure, the liquid can push the lock core 3 open by squeezing and flow out naturally. Among them, with the reciprocating motion of the lifting tube 6, the stirring wheel 10 connected to the bottom of the lifting tube 6 will be rotated by the action of the screw 13, and the multiple stirring rods 16 fixed to the top of the stirring wheel 10 will rotate synchronously to achieve stirring of the liquid. The multiple fixed rods 12 fixed between the liquid collection tube 7 and the screw 13 play the role of fixing the screw 13. Whenever the stirring wheel 10 rotates under the action of the screw 13, the multiple sliding balls 14 arranged in the limit groove can be moved by themselves The sliding friction between the components is partially converted into rolling friction to reduce the friction coefficient. The filling block 15 arranged between the multiple sliding beads 14 can limit the position of the multiple sliding beads 14 by itself, prevent the sliding beads 14 from gathering, and prevent the stirring wheel 10 from falling off from the bottom of the pulling tube 6. The fixed block fixed between the stirring rod 16 and the stirring wheel 10 increases the contact area between the stirring rod 16 and the stirring wheel 10 by itself, and the stirring blade 17 fixed to the side wall of the multiple stirring rods 16 increases the contact area between the stirring rod 16 and the liquid by itself. Whenever the liquid in the liquid storage bottle 4 is exhausted, the liquid collecting plate 22 fixed inside the liquid storage bottle 4 can collect the liquid at the bottom of the plastic hose 8 by itself, and the user can use the rubber suction cup 18 to pull the liquid storage bottle 4 It is fixed on the surface of ceramic, glass and other media to maintain the stability of the liquid storage bottle 4 and the lifting pump head. Whenever the lifting tube 6 moves to the bottom, the multiple limit blocks 21 fixedly connected to the bottom of the lifting tube 6 will first come into contact with the liquid accumulation tube 7. After the multiple limit blocks 21 come into contact with the liquid accumulation tube 7, the lifting tube 6 and the components connected to the lifting tube 6 will maintain the distance between themselves and the liquid accumulation tube 7. The sealing sheet 20 can seal the threaded cap 19 and the liquid storage bottle 4 by deforming under its own force. During the process, whenever the user tightens the threaded cap 19 on the top of the liquid storage bottle 4, the top of the liquid storage bottle 4 will squeeze the sealing sheet 20 fixedly connected to the bottom of the threaded cap 19, and the support block 23 fixedly connected between the liquid storage bottle 4 and the liquid collecting plate 22 can provide support for the liquid collecting plate 22 by itself.
