Description

Technical Field

[0001] The invention relates to a pressing pump which prevents a pressing head from rotating and opening. Background Art

[0002] At present, a general press pump includes a body, a lock cover disposed on the upper end of the body, a press head threadedly connected to the lock cover, and a screw cover sleeved on the outside of the body and located below the lock cover. The press head has a screwed-in state and a screwed-out state relative to the lock cover. In the screwed-in state, the press head cannot move up and down, thereby preventing liquid from spilling during transportation or storage. In the screwed-out state, the press head can move up and down for normal use by the user.

[0003] However, during the transportation of the pump, the push head is easily hit and rotated. After rotating to a certain angle, the push head is easily separated from the lock cover, which causes the liquid to be squeezed out when the push head is pressed. In addition, in order to achieve the reciprocating lifting and lowering movement of the push head, a spring part is generally provided between the push head and the lock cover. When the push head is in a tightened state, the spring part is in a compressed state for a long time, resulting in insufficient rebound force when the pump is working normally, affecting the user experience.

[0027] See also Figures 1 to 4 A pressing pump capable of preventing a pressing head from rotating and opening includes: a main body 100, wherein a floating member 200 capable of being lifted and lowered relative to the main body 100 is disposed inside the main body 100, and the floating member 200 has a first height position and a second height position relative to the main body 100; a pump core assembly 300 movably disposed on the floating member 200, and the upper end of the pump core assembly 300 is connected to a pressing head 310 extending out of the main body 100; an elastic member 400 disposed between the floating member 200 and the pressing head 310, and used for driving the pressing head 310 to extend upward; a linkage locking mechanism disposed between the main body 100 and the floating member 200, and capable of stabilizing the floating member 200 at a first height position to prevent the pressing head 310 from moving downward, or stabilizing the floating member 200 at a second height position so that the pressing head 310 can move up and down.

[0028] When the press pump is transported or stored, the floating member 200 is at a first height position. At this time, when the pressing head 310 is rotated by an external force, it can only idle relative to the main body 100 and the floating member 200. The pressing head 310 does not have a downward movement position when under pressure to prevent liquid overflow. When the discharge function of the press pump needs to be turned on, the interlocking locking mechanism is used to drive the floating member 200 to switch to the second height position. The pump core assembly 300 and the pressing head 310 move upward a certain distance with the floating member 200. At this time, the pressing head 310 can move downward relative to the floating member 200 and the main body 100 to achieve discharge.

[0029] See also Figures 1 to 4 In some embodiments of the present invention, the linkage locking mechanism includes a perforated guide groove 510 provided on the main body 100, a guide portion 520 provided on the floating member 200 and a rotating member 530 rotatably provided on the outside of the main body 100, the perforated guide groove 510 includes a spiral rising groove 511 spirally rising around the central axis of the main body 100, a first positioning groove 512 intersectingly connected to the lower end of the spiral rising groove 511 and a second positioning groove 513 intersectingly connected to the upper end of the spiral rising groove 511, the rotating member 530 is provided with a vertical guide groove 531, the guide portion 520 is sequentially penetrated through the perforated guide groove 510 and the vertical guide groove 531, when the rotating member 530 rotates relative to the main body 100, the side wall of the vertical guide groove 531 abuts against the guide portion 520 to drive the guide portion 520 to move between the first positioning groove 512, the spiral rising groove 511 and the second positioning groove 513. It should be noted that when the pump is transported or stored, when the floating member 200 is at the first height position, the pressing head 310 abuts against the upper end of the body 100 or the height gap between the pressing head 310 and the body 100 is very small, which is not enough to discharge the liquid by pressing the pressing head 310. At this time, the guide portion 520 is located in the first positioning groove 512 and at the lower part of the vertical guide groove 531; then when the user rotates the rotating member 530, the vertical guide groove 531 drives the guide portion 520 away from the first positioning groove 512. The first positioning groove 512 is opened and enters the rotation groove 511. As the rotating member 530 continues to rotate, the guide portion 520 gradually moves from the lower end of the rotation groove 511 to the upper end of the rotation groove 511 and then enters the second positioning groove 513. The guide portion 520 also moves from the lower part of the vertical guide groove 531 to the upper part of the vertical guide groove 531. At the same time, the floating member 200 rotates and rises, thereby switching to the second height position, and the pressing head 310 can be pressed down and moved relative to the main body 100.

[0030] See also Figure 3 and Figure 4In some embodiments of the present invention, the upper edge of the body 100 is provided with an installation entrance 514 that is connected to the upper end of the rotation groove 511 and the second positioning groove 513. The installation entrance 514 is used for the guide part 520 to enter the perforated guide groove 510. It should be noted that during assembly, the floating member 200 is inserted into the body 100, and the guide part 520 on the floating member 200 is aligned with the installation entrance 514 for insertion, and the vertical guide groove 531 of the rotating member 530 is aligned with the guide part 520 so that the guide groove is embedded. The above structure is conducive to the assembly of the pressing pump.

[0031] See also Figure 4 In some embodiments of the present invention, the first positioning groove 512 is arranged around the circumference of the body 100, and the second positioning groove 513 is arranged around the circumference of the body 100 and tilted downward. It can be understood that when the rotating member 530 rotates at a small angle, the guide part 520 moves in the first positioning groove 512 and does not enter the spiral groove 511. At this time, the floating member 200 is always at the first height position to prevent the pressing pump from easily starting the discharge function; when the guide part 520 enters the second positioning groove 513, since the second positioning groove 513 surrounds the circumference of the body 100 and tilted downward, when the pressing head 310 is pressed downward, the guide part 520 will not re-enter the spiral groove 511 due to a slight deflection of the floating member 200, thereby ensuring the normal pressing work of the pressing pump.

[0032] See also Figure 1 and Figure 4 In some embodiments of the present invention, a ring sleeve 110 is arranged at intervals on the outer peripheral wall of the body 100, and an annular groove is defined between the ring sleeve 110 and the outer peripheral wall of the body 100. The rotating member 530 includes a circular ring sleeve 532 located in the annular groove, a vertical guide groove 531 is provided on the side wall of the circular ring sleeve 532, and a perforated guide groove 510 is provided on the outer peripheral wall of the body 100. The floating member 200 can rotate relative to the body 100, and the guide portion 520 is provided on the outer peripheral wall of the floating member 200 to pass through the perforated guide groove 510 and the vertical guide groove 531 in sequence. It can be understood that the annular groove plays a role of rotational guidance for the circular ring sleeve 532, so as to realize the rotation of the rotating member 530 relative to the body 100. Moreover, the pressing pump with the above structure is simple in structure, easy to produce, and also conducive to improving the compactness of the structure. Among them, the outer part of the annular sleeve 110 is also rotatably provided with a locking cover 600 for connecting the bottle body.

[0033] See also Figure 1 and Figure 2In some embodiments of the present invention, the upper end of the annular sleeve 110 is provided with a circle of first annular flange 120 folded outward, and the rotating member 530 further includes a rotary cover 533 connected to the outer periphery of the upper end of the circular sleeve 532, and the rotary cover 533 is provided with a second annular flange 534 folded inward to abut against the first annular flange 120, and the second annular flange 534 cooperates with the first annular flange 120 so that the rotating member 530 can only rotate relative to the body 100. Among them, the second annular flange 534 extends downward along the lower surface of the rotary cover 533, and the second annular flange 534 hooks the first annular flange 120 to prevent the rotating member 530 from being separated upward relative to the body 100.

[0034] See also Figure 2 and Figure 3 In some embodiments of the present invention, in order to improve the working reliability of the linkage locking mechanism and also make the relative movement between the rotating member 530, the floating member 200 and the body 100 more stable, the floating member 200 is a sleeve that can rotate and move up and down inside the body 100, and the pump core assembly 300 is inserted into the sleeve. The outer peripheral wall of the sleeve is provided with a plurality of guide portions 520 arranged circumferentially around the central axis of the body 100, and the number of the perforated guide grooves 510 and the vertical guide grooves 531 is consistent with the number of the guide portions 520, and the guide portions 520, the perforated guide grooves 510 and the vertical guide grooves 531 are arranged one by one. In this embodiment, there are two guide portions 520, two perforated guide grooves 510 and two vertical guide grooves 531.

[0035] See also Figure 1 and Figure 2 In some embodiments of the present invention, a ring plate 210 is provided inside the sleeve, and the pump core assembly 300 passes upward along the middle of the ring plate 210. The elastic member 400 is a plastic spring whose two ends respectively abut against the ring plate 210 and the pressing head 310, which is beneficial to reduce the cost of the pressing pump.

[0036] In some embodiments of the present invention, the guide part 520 is a column protruding along the outer peripheral wall of the sleeve, the guide part 520, the sleeve and the annular plate 210 are an integrated plastic structure, and the pump core assembly 300, the pressing head 310, the body 100, and the rotating member 530 are all made of plastic. It can be understood that each component of the pressing pump of the above structure is made of material, which reduces the difficulty of recycling, is also beneficial to environmental protection, and can also reduce costs.

[0037] See also Figure 1 and Figure 2In some embodiments of the present invention, when the floating member 200 is at the first height position or the second height position, the elastic member 400 is in an extended state. It should be noted that, compared with the traditional pressing pump, when the pressing head 310 of the pressing pump of the present invention is in the storage state, since the floating member 200, the pump core assembly 300, and the pressing head 310 are lowered a certain distance relative to the body 100, there is no need to compress the elastic member 400. When the pressing head 310 is in the extended state, the floating member 200, the pump core assembly 300, and the pressing head 310 are raised a certain distance relative to the body 100. At this time, the pressing head 310 can be directly pressed to achieve discharge, the service life of the elastic member 400 is guaranteed, and the rebound stroke of the pressing head 310 of the pressing pump is more stable.

[0038] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
