[0001] The invention relates to the technical field of lotion pumps on the top of lotion bottles, in particular to a spring external structure of a lotion pump nozzle. Background Art

[0002] Lotion pumps are widely used in daily chemical products such as shampoo and shower gel to dispense the products from containers containing these products. In order to compensate for the negative pressure generated during the process of the lotion pump pumping the product in the container, a balancing air hole is provided in the lotion pump.

[0003] Chinese patent application number CN201620760806.5 discloses a lotion pump having parts such as a pressure head, a toothed sleeve, a cylinder head and a cylinder, wherein a first sleeve is formed on the pressure head, and the first sleeve includes a first sealing structure; a second sleeve is formed on the toothed sleeve or the cylinder head, and a second sealing structure corresponding to the first sealing is formed on the second sleeve. When the lotion pump is in a locked state or a ready-to-use state, the first sealing structure contacts the second sealing structure.

[0004] After the lotion pump applied to the above structure is used on the lotion bottle for a long time, the lotion in the lotion bottle will become less. Therefore, in actual use, it is difficult to suck the lotion at the bottom of the lotion bottle upward through the straw of the lotion pump, especially when the bottom of some bottles is convex. The remaining lotion at the bottom will flow to the periphery of the bottom of the bottle, and it is difficult to suck it with the vertical straw. At this time, throwing away the lotion bottle without completely using up the lotion will cause waste. Summary of the invention

[0005] The purpose of the present invention is to provide a spring external structure of a lotion pump nozzle, so as to solve the problem that after the lotion pump applied to the above structure is placed on a lotion bottle and used for a long time, the lotion in the lotion bottle will become less. Therefore, in actual use, it is difficult to suck out the lotion at the bottom of the lotion bottle through the suction tube of the lotion pump, especially when the bottom of some bottles is convex, the remaining lotion at the bottom will flow to the periphery of the bottle bottom, and it is difficult to suck it with the vertical suction tube. At this time, the lotion bottle without completely using up the lotion will be thrown away, which will cause waste.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a spring external structure of a lotion pump nozzle, comprising a pump body; a screw cap is installed on the top of the pump body, and a guide seat is glued on the outer wall of the pump body; a spring is sleeved in the tube cavity of the pump body, and a straw is inserted in the inner circle of the spring, and the straw and the original pressure rod and piston sleeve assembly in the push cap form an existing elastic pressure type lotion pump body mechanism through the spring; the tops of the push cap and the screw cap are respectively provided with a through hole 1 and a through hole 2 of a circular through hole structure, and the through hole 1 and the through hole 2 are on the same vertical axis; the screw cap fixes the lotion nozzle mechanism on the lotion bottle through an internal thread.

[0007] Furthermore: a steel wire rod is passed downward through the through hole 1 on the push cover, and the steel wire rod continues to pass downward through the through hole 2 on the rotary cover and enters the guide seat.

[0008] Furthermore: the guide hole of the guide seat is a lower left inclined structure. When the wire rod passes through the guide seat, the inclined guide hole guides it to pass out in a lower left style.

[0009] Further: the steel wire rod is a structure with one side bent, and is located on one side of the straw.

[0010] Furthermore: a rubber seat is glued on the top surface of the second through hole on the screw cap, and a threaded hole is provided in the rubber seat.

[0011] Furthermore: a locking column is sleeved on the outer side of the straw, and the locking column and the steel wire rod are in a threaded connection relationship.

[0012] Furthermore, the locking column is also matched with the threaded mounting hole of the rubber seat through the threaded section at the bottom end, so that the steel wire rod threadedly connected to the locking column can be fixed in position.

[0013] Furthermore: a more flexible corrugated section is provided on the straw, and a sleeve is provided on one side of the straw, and the bottom end of the steel wire rod is inserted into the sleeve.

[0014] Furthermore: the suction port at the bottom of the straw is an inclined incision structure, and a branch pipe is passed through the bottom end of the straw, and a downward overflow hole is opened at the bottom end of the branch pipe.

[0015] Furthermore: the branch pipe and the bottom suction section of the suction pipe are arranged in an eight-shaped pattern.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figures 1 to 6The present invention provides an embodiment: a spring external structure of a lotion pump nozzle, comprising a pump body 1; a screw cap 3 is installed on the top of the pump body 1, and a guide seat 2 is glued on the outer wall of the pump body 1; a spring 13 is sleeved in the tube cavity of the pump body 1, and a suction pipe 8 is inserted in the inner circle of the spring 13, and the suction pipe 8 and the original pressure rod and piston sleeve assembly in the push cap 4 form an existing elastic pressure type lotion pump body mechanism through the spring 13, which is a prior art and serves the connection relationship conditions for the description of this design, so it is further described here; the tops of the push cap 4 and the screw cap 3 are respectively provided with circular through-hole structures The structure has a through hole 1 601 and a through hole 2 602, and the through hole 1 601 and the through hole 2 602 are on the same vertical axis; the screw cap 3 fixes the lotion spray head mechanism on the lotion bottle through an internal thread, a steel wire rod 7 penetrates downward through the through hole 1 601 on the press cap 4, and the steel wire rod 7 continues to pass downward through the through hole 2 602 on the screw cap 3 and enters the guide seat 2, the steel wire rod 7 can be pulled up and down, and when they are pulled, they move into the guide seat 2 at the bottom, and because the hole cavity of the guide seat 2 is a lower left inclined structure, it conforms to the curved direction of the lower left curved steel wire rod 7.

[0026] Among them: the steel wire rod 7 is a structure bent on one side, which is located on one side of the straw 8. Since the steel wire rod 7 itself is an arc-shaped wire rod member slightly bent to the left, it tends to one side when pressing down.

[0027] Among them: Figure 5 , Figure 6 As shown, a rubber seat 14 is glued to the top surface of the second through-hole 602 provided on the rotary cover 3, and a threaded hole is provided in the rubber seat 14 to form a threaded connection mechanism. A locking column 15 is sleeved on the outer side of the straw 8, and the locking column 15 and the wire rod 7 are in a threaded connection relationship. The locking column 15 is also matched with the threaded mounting hole of the rubber seat 14 through the threaded section at the bottom, so that the wire rod 7 threadedly connected to the locking column 15 can be fixed in position. It can be seen that when the present mechanism is installed on the lotion bottle for use, the straw 8 is in a vertical state to better absorb the lotion in the bottle. At this time, the wire rod 7 is locked on the rubber seat 14 by the locking column 15 and does not work. Only after the locking column 15 is screwed out of the rubber seat 14, the wire rod 7 can perform a pulling and pressing action. It can be seen from the figure that a hand notch is provided on the front side of the press cover 4 to facilitate a person to reach out from the front side to rotate the locking column 15 and the rubber seat 14.

[0028] Among them: a more flexible corrugated section 9 is provided on the straw 8 for facilitating the bending action of the straw 8, and a sleeve 10 is provided on one side of the straw 8, and the bottom end of the wire rod 7 is inserted into the sleeve 10, that is to say, the above-mentioned steel wire rod 7 that can press down and pull up, the above-mentioned action produced, the ultimate purpose of which is to serve the straw 8.

[0029] Among them: the suction port of the bottom section of the straw 8 is an inclined incision structure, which is convenient for sticking to the bottom of the lotion bottle and absorbing liquid upward over a large area, and a branch pipe 11 is also penetrated at the bottom end of the straw 8, and the bottom end of the branch pipe 11 is provided with an overflow hole 12 facing downward to form a branched liquid absorption structure. When the straw 8 is bent by the left pressure of the steel wire rod 7, since the branch pipe 11 and the bottom suction section of the straw 8 are arranged in an eight-shaped style, the branch pipe 11 expands in the opposite direction, so that the suction port of the straw 8 and the suction port of the branch pipe 11 are in opposite directions to the bottom of the lotion bottle, especially the bottom of the bottle is convex, which causes the part of the lotion flowing to the periphery of the bottom of the bottle to be bidirectionally absorbed, and the functional structure is more reasonable.

[0030] Working principle: when the lotion pump body mechanism is installed on the lotion bottle for use, when the lotion water level in the lotion bottle is high, under the action of the existing lotion pump, the straw 8 normally sucks out the lotion upwards, which is similar to the use method of lotion bottles such as shampoo. However, what the present design needs to point out is that when the lotion water level in the lotion bottle is low, the straw 8 will not be sucked thoroughly, especially when the lotion pump is installed on the lotion bottle with an upwardly convex bottom, a large part of the lotion will be scattered on the lower edge area around the bottom of the bottle due to the middle convexity. At this time, the hand notch provided on the front side of the press cover 4 can be passed through to spirally separate the locking column 15 from the rubber seat 14. At this time, the steel wire rod 7 in the original fixed state becomes a state that can be pressed down. When it is pressed down, the straw 8 will be pressed down and bend to the side of the bottle bottom, so that a large amount of lotion in the lower edge area around the bottom of the bottle with an upwardly convex bottom is more thoroughly sucked upwards, and as Figure 1 , Figure 2 As shown, the bottom end of the branch tube 11 is provided with an overflow hole 12 facing downwards, forming a branched liquid suction structure. When the suction tube 8 is bent by the left pressure of the steel wire rod 7, since the branch tube 11 and the bottom suction section of the suction tube 8 are arranged in an eight-shaped pattern, the branch tube 11 expands in the opposite direction, so that the suction port of the suction tube 8 and the suction port of the branch tube 11 are in opposite directions to the bottom of the lotion bottle, especially the bottom of the bottle is convex, so that the part of the lotion flowing to the periphery of the bottom of the bottle can be sucked in two directions, and the functional structure is more reasonable.

[0031] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
