Description

A pressing pump that prevents the pressing head from rotating to open Technical Field

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

[0002] Currently, a typical pump consists of a main body, a locking cover mounted on the upper end of the main body, a push-button screwed to the locking cover, and a threaded cover mounted on the exterior of the main body and located below the locking cover. The push-button screw can be screwed into and out of the locking cover. In the screwed-in state, the push-button screw cannot move up or down, thus preventing liquid from spilling during transportation or storage. In the out of the screwed-out state, the push-button screw can move up and down for normal use.

[0003] However, during transportation, the push-button head is susceptible to collisions and rotation. After rotating to a certain angle, the push-button head can easily separate from the locking cap, causing liquid to be squeezed out when the push-button head is pressed. Furthermore, to achieve the reciprocating movement of the push-button head, a spring is typically installed between the push-button head and the locking cap. When the push-button head is tightened, the spring remains compressed for a long time, resulting in insufficient rebound force during normal operation of the push-button pump, affecting the user experience.

[0004] Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a pump with a rotation-resistant push button.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] 1 to 4 , a press pump that prevents a push head from rotating to open according to the present invention comprises: a main body 100, wherein a floating member 200 is provided in the main body 100 and can be raised and lowered relative to 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, which is movably provided on the floating member 200, and the upper end of the pump core assembly 300 is connected to a push head 310 extending out of the main body 100; an elastic member 400, which is provided between the floating member 200 and the push head 310 and is used to drive the push head 310 to extend upward; a linkage locking mechanism, which is provided between the main body 100 and the floating member 200 and can stabilize the floating member 200 at the first height position to prevent the push head 310 from moving downward, or stabilize the floating member 200 at the second height position so that the push head 310 can move up and down.

[0029] When the press pump is transported or stored, the floating part 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 part 200. The pressing head 310 does not have a downward travel 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 part 200 to switch to the second height position. The pump core assembly 300 and the pressing head 310 move upward a certain distance following the floating part 200. At this time, the pressing head 310 can move downward relative to the floating part 200 and the main body 100 to achieve discharge.

[0030] 1 to 4 , in some embodiments of the present invention, the interlocking 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 spirally ascending groove 511 surrounding the central axis of the main body 100, a first positioning groove 512 intersectingly connected to the lower end of the rotating groove 511, and a second positioning groove 513 intersectingly connected to the upper end of the rotating 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 rotating groove 511, and the second positioning groove 513. It should be noted that when the pump is being 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 part 530 continues to rotate, the guide part 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 part 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 part 200 rotates and rises, thereby switching to the second height position, and the pressing head 310 can be pressed down relative to the main body 100.

[0031] 3 and 4 , in some embodiments of the present invention, the upper edge of the body 100 is provided with an installation inlet 514 that communicates with the upper end of the rotation groove 511 and the second positioning groove 513. The installation inlet 514 is used to allow the guide portion 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 portion 520 on the floating member 200 is aligned with the installation inlet 514. The vertical guide groove 531 of the rotating member 530 is then aligned with the guide portion 520 so that the guide groove is inserted. This structure facilitates assembly of the press pump.

[0032] Referring to Figure 4 , in some embodiments of the present invention, the first positioning groove 512 is disposed around the circumference of the body 100, and the second positioning groove 513 is disposed around the circumference of the body 100 and tilted downward. It is understood that when the rotating member 530 rotates a small angle, the guide portion 520 moves within the first positioning groove 512 and does not enter the rotation groove 511. At this time, the floating member 200 remains at the first height position, preventing the pump from easily activating the discharge function. When the guide portion 520 enters the second positioning groove 513, because 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 portion 520 will not re-enter the rotation groove 511 due to slight deflection of the floating member 200, thereby ensuring normal pressing operation of the pump.

[0033] Referring to Figures 1 and 4 , in some embodiments of the present invention, an annular sleeve 110 is disposed on the outer circumferential wall of the body 100. An annular recess is defined between the annular sleeve 110 and the outer circumferential wall of the body 100. A rotating member 530 includes a circular sleeve 532 positioned within the annular recess, a vertical guide groove 531 formed in the sidewall of the circular sleeve 532, and a perforated guide groove 510 formed in the outer circumferential wall of the body 100. The floating member 200 is rotatable relative to the body 100, and a guide portion 520 is disposed on the outer circumferential wall of the floating member 200 to sequentially pass through the perforated guide groove 510 and the vertical guide groove 531. It will be appreciated that the annular recess serves as a rotational guide for the circular sleeve 532, thereby enabling the rotating member 530 to rotate relative to the body 100. Furthermore, the pump structure described above is simple in construction, easy to manufacture, and also facilitates compactness. Furthermore, a locking cap 600 for connecting to the bottle body is rotatably disposed on the outer portion of the annular sleeve 110.

[0034] 1 and 2 , in some embodiments of the present invention, the upper end of the annular sleeve 110 is provided with a first annular flange 120 that is folded outward. The rotating member 530 further includes a rotary cover 533 connected to the outer periphery of the upper end of the circular sleeve 532. The rotary cover 533 is provided with a second annular flange 534 that is folded inward to abut against the first annular flange 120. The second annular flange 534 cooperates with the first annular flange 120 to allow the rotating member 530 to rotate only relative to the body 100. The second annular flange 534 extends downwardly along the lower surface of the rotary cover 533 and hooks onto the first annular flange 120 to prevent the rotating member 530 from detaching upward from the body 100.

[0035] 2 and 3 , in some embodiments of the present invention, to improve the reliability of the interlocking locking mechanism and further stabilize the relative motion between the rotating member 530 , the floating member 200 , and the body 100 , the floating member 200 is a sleeve that can rotate and move up and down within the body 100 . 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 circumferentially arranged around the central axis of the body 100 . The number of perforated guide grooves 510 and vertical guide grooves 531 matches the number of guide portions 520 , and the guide portions 520 , perforated guide grooves 510 , and vertical guide grooves 531 are provided in a one-to-one correspondence. In this embodiment, two guide portions 520 , two perforated guide grooves 510 , and two vertical guide grooves 531 are provided.

[0036] Referring to Figures 1 and 2, in some embodiments of the present invention, a ring plate 210 is provided inside the sleeve, the pump core assembly 300 passes upward along the middle of the ring plate 210, and 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 reducing the cost of the pressing pump.

[0037] In some embodiments of the present invention, the guide portion 520 is a columnar body protruding from the outer circumferential wall of the sleeve. The guide portion 520, the sleeve, and the annular plate 210 are integrally formed from plastic. The pump core assembly 300, the pressing head 310, the body 100, and the rotating member 530 are all constructed from plastic. It will be appreciated that the components of the pump structure described above are constructed from the same plastic material, which reduces the difficulty of recycling, is environmentally friendly, and reduces costs.

[0038] 1 and 2 , in 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 to conventional pumps, when the push head 310 of the pump of the present invention is in the stowed state, since the floating member 200, the pump core assembly 300, and the push head 310 are all lowered a certain distance relative to the body 100, there is no need to compress the elastic member 400. When the push head 310 is in the extended state, the floating member 200, the pump core assembly 300, and the push head 310 are all raised a certain distance relative to the body 100. At this time, liquid can be discharged by directly pressing the push head 310, thereby ensuring the service life of the elastic member 400 and making the rebound stroke of the push head 310 of the pump more stable.

[0039] The technical features of the above embodiments can be combined arbitrarily. 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.

[0040] While 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 invention, and that the scope of the invention is defined by the claims and their equivalents.
