Description

Technical Field

[0001] This utility model relates to the field of pump head technology, specifically to a press pump head. Background Technology

[0002] Common push-button pump heads typically have a fixed dispensing direction. During carrying or transportation, the protruding pump head is easily squeezed, leading to liquid leakage, waste, and contamination. Although some products come with a separate dust cover, the dust cover is easily lost and does not fundamentally prevent accidental pressing. Other designs have a bendable straw, but its main purpose is to adjust the dispensing angle and it does not have a reliable locking function to prevent accidental pressing.

[0003] In view of this, this application has conducted in-depth research on the above-mentioned issues, resulting in this case. Utility Model Content

[0004] The purpose of this invention is to provide a portable and easy-to-operate press pump head.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A push-button pump head includes a pump head body; the pump head body includes a push-button at the top and a liquid outlet head for discharging liquid; the push-button and the liquid outlet head are rotatably connected by a rotating rod, the push-button has a rotating rod mounting hole for mounting the rotating rod, and the liquid outlet head has a rotating rod through hole for the rotating rod to pass through; the push-button has a push-button outlet for discharging liquid, and the liquid outlet head has a guide cavity formed inside, the guide cavity having a guide inlet communicating with the push-button outlet and a guide outlet for discharging liquid; the pump head body also includes a positioning component for positioning the liquid outlet head. The positioning component includes a rotating rod mounting block for mounting the rotating rod on the pressing head, a return spring for resetting the rotating rod, a positioning boss for positioning the dispensing head formed on the rotating rod, a positioning groove for positioning the dispensing head formed on the dispensing head, the positioning groove including a dispensing positioning groove for positioning the dispensing head in the dispensing position and a closing positioning groove for positioning the dispensing head in the closed position, a spring receiving groove for accommodating the return spring formed on the rotating rod, and a rotation limiting component for limiting the rotation of the rotating rod.

[0007] The rotation limiting assembly includes a limiting boss formed on the pressing head and corresponding to the rotating rod mounting block; the limiting boss has a block groove for the rotating rod mounting block to slide, the block groove is polygonal in shape, and the shape of the rotating rod mounting block corresponds to the block groove.

[0008] The rotating rod has a holding section for axial movement of the rotating rod, and the holding section is located on the side where the positioning boss of the rotating rod is located.

[0009] The holding section is a rotating body, and its diameter gradually decreases from both ends toward the middle.

[0010] The length of the liquid outlet head is greater than the pressing stroke of the pump head body.

[0028] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0029] A type of press pump head, such as Figures 1-9As shown, the pump head body 1 includes a pressing head 2 at the top and a liquid outlet head 3 for discharging liquid. The pressing head 2 and the liquid outlet head 3 are rotatably connected by a rotating rod 4. The pressing head 2 is provided with a rotating rod mounting hole 21 for mounting the rotating rod 4, and the liquid outlet head 3 is provided with a rotating rod through hole 31 for the rotating rod 4 to pass through. The pressing head 2 has a pressing outlet 22 for discharging liquid, and the liquid outlet head 3 has a guide cavity formed inside. The guide cavity has a guide inlet 32 ​​connected to the pressing outlet 22 and a guide outlet 33 for discharging liquid. The pump head body 1 also includes a positioning component 5 for positioning the liquid outlet head 3. The pressing head 2 and the dispensing head 3 are hinged by a rotating rod 4. The rotating rod 4 passes through the rotating rod through-hole 31, and its end is installed in the rotating rod mounting hole 21, allowing the dispensing head 3 to rotate relative to the pressing head 2 around the axis of the rotating rod 4. In actual use, when the pressing head 2 is pressed, liquid flows from the pressing outlet 22 through the guide inlet 32 ​​into the guide cavity, and then out through the guide outlet 33. When the pump head needs to be closed or stored, the positioning component 5 is released, and the dispensing head 3 is rotated downwards until it is closed. The positioning component 5 then positions the dispensing head 3 at this position. During this process, the guide inlet 32 ​​and the pressing outlet 22 are misaligned, thus cutting off the flow and preventing liquid leakage due to accidental operation during storage or closure. Simultaneously, keeping the dispensing head 3 in the closed state also facilitates overall storage. The positioning component 5 allows the dispensing head 3 to be fixed in either the dispensing or closed state. Furthermore, the positioning component 5 includes a rotating rod mounting block 51 for mounting the rotating rod 4 on the pressing head 2, and a return spring 52 for resetting the rotating rod 4; a positioning boss 41 for positioning the dispensing head 3 is formed on the rotating rod 4; the dispensing head 3 has a positioning groove corresponding to the positioning boss 41, the positioning groove including a dispensing positioning groove 34 for positioning the dispensing head 3 in the dispensing position, and a closing positioning groove 35 for positioning the dispensing head 3 in the closed position; a spring receiving groove 36 for accommodating the return spring 52 is formed on the rotating rod 4; the positioning component 5 also includes a rotation limiting component for restricting the rotation of the rotating rod 4. In its natural state, the elastic force of the return spring 52 pushes the rotating rod 4 inward, causing the positioning boss 41 to engage in the positioning groove. When the user needs to rotate the dispensing head 3 to the closed position, he pulls along the axis of the rotating rod 4 in the opposite direction to the rotating rod mounting block 51, so that the positioning boss 41 disengages from the dispensing positioning groove 34. Then, he rotates the dispensing head 3 to the closed position and releases the rotating rod 4. Under the action of the return spring 52, the positioning boss 41 is locked into the closing positioning groove 35, so that the press-out outlet 22 is closed. The operation is simple, the locking structure is stable, and it effectively prevents the dispensing outlet from rotating due to accidental contact.Furthermore, the rotation limiting assembly includes a limiting boss 23 formed on the pressing head 2 and corresponding to the rotating rod mounting block 51; the limiting boss 23 has a block groove 231 for the rotating rod mounting block 51 to slide, the block groove 231 is polygonal in shape, and the shape of the rotating rod mounting block 51 corresponds to the block groove 231. Since the circumferential degree of freedom of the rotating rod mounting block is restricted by the polygonal block groove 231, the rotating rod 4 fixed to the rotating rod mounting block 51 cannot rotate either. The rotation of the liquid outlet head 3 occurs relative to the fixed rotating rod 4. This structure ensures a stable relative positional relationship between the positioning boss 41 and the positioning groove, avoiding positioning failure caused by the accidental rotation of the rotating rod 4 itself, making the positioning more accurate and reliable. Furthermore, the rotating rod 4 has a holding section 42 for axial movement. The holding section 42 is located on the side where the positioning boss 41 of the rotating rod 4 is located. By pinching the holding section with their fingers, the user can easily pull the rotating rod 4 axially, thereby compressing the return spring 52 and causing the positioning boss 41 to disengage from the positioning groove, making the state switching operation more effortless, intuitive, and easy to achieve. Furthermore, the holding section 42 is a rotating body, and the diameter of the holding section 42 gradually decreases from both ends to the middle. This spindle-shaped or streamlined design, which is thinner in the middle and slightly thicker at both ends, perfectly fits the curve of the fingertip, significantly improving the comfort and anti-slip performance when pinching. It can be operated stably even when the hands are wet and slippery, further optimizing the user experience.

[0030] The length of the dispensing head 3 is greater than the pressing stroke of the pump head body 1. This means that even when the dispensing head 3 is in the closed state, if the user accidentally presses down the pressing head 2, the dispensing head 3 can limit the downward pressing stroke of the pressing head 2, preventing the user from pressing down the pressing head 2 and thus avoiding liquid leakage, achieving the anti-accidental pressure function. Furthermore, the pressing head 2 is also equipped with a shielding part 24 to prevent dust from entering the guide inlet 32. In the closed state, the shielding part 24 can form a physical barrier to prevent dust, lint, and other foreign objects from entering the guide cavity inside the dispensing head 3 from the guide inlet 32, providing a good dustproof effect. It is especially suitable for long-term storage in complex environments such as bathrooms and kitchens, ensuring the hygiene and safety of the product.

[0031] The product form of this utility model is not limited to the illustrations and embodiments in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of this utility model.
