Description

Technical Field

[0001] This utility model relates to the field of shampoo pump head technology, specifically a shampoo pump head anti-leakage pressing mechanism. Background Technology

[0002] The shampoo pump head is a component installed on top of the shampoo bottle to control the dispensing of shampoo. By pressing the pump head, negative pressure is created in the pump body, drawing the shampoo out of the bottle through the straw. This allows users to precisely control the amount of shampoo dispensed each time, avoiding waste, and also preventing excessive contact between the shampoo and the outside environment, reducing contamination and evaporation, and maintaining the quality of the shampoo.

[0003] For example, Chinese Patent Application No. 201620775566.6 discloses a shampoo bottle. The shampoo bottle includes a bottle body with a receiving space, a liquid-pressing part that cooperates with the bottle body, and a straw extending from the liquid-pressing part. The straw is circularly curved along the inner wall of the bottle bottom, and multiple holes are opened on the side of the straw near the bottle bottom. Compared with related technologies, the straw of the shampoo bottle provided by this utility model extends to the bottom of the bottle in a circular structure, so that the straw is located in various corners of the bottle bottom. This avoids the phenomenon that when the shampoo liquid decreases to a certain level, the straw length is insufficient or the straw is fixed in a certain corner, resulting in the shampoo liquid not being able to be drawn out, thus avoiding waste.

[0004] When using a shampoo pump, people typically press down on the top of the pump head with their palm or fingers to squeeze the shampoo out of the bottle. However, after the shampoo is sprayed out, some liquid often remains inside the pump head. This residue causes shampoo to continuously leak from the pump head's nozzle, resulting in leakage or dripping.

[0005] Therefore, it is necessary to redesign and modify the anti-leakage pressing mechanism of the shampoo pump head to effectively prevent leakage and dripping. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a shampoo pump head anti-leakage pressing mechanism, which has the advantages of being easy to use and solves the problems of leakage and dripping.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shampoo pump head anti-leakage pressing mechanism, comprising a bottle body, a straw installed on the upper side of the bottle body, a pump head installed on the upper side of the straw, an anti-leakage mechanism provided on the upper side of the bottle body, the anti-leakage mechanism comprising a fixed cylinder fixedly connected to the front and rear sides of the pump head, a rotating rod slidably connected to the inner wall of the fixed cylinder, a lower flap plate fixedly connected to the left side of the rotating rod, a connecting rod fixedly connected to the inner side of the lower flap plate, a blocking block fixedly connected to the inner side of the connecting rod, the blocking block being used to seal the water outlet of the pump head, and an unsealing mechanism provided on the upper side of the bottle body.

[0008] As a preferred embodiment of this utility model, the unsealing mechanism includes a pressure plate movably connected to the upper side of the lower flip plate, a synchronization plate fixedly connected to the right side of the pressure plate, a slide plate fixedly connected to the lower side of the synchronization plate, a limit block slidably connected to the surface of the slide plate, a limit plate slidably connected to the inner wall of the limit block, and a limit plate fixedly connected to the right side of the slide plate on the left side.

[0009] As a preferred embodiment of this invention, a septum is fixedly connected to the right side of the plug, and the septum cooperates with the plug to more effectively seal the outlet of the pump head.

[0010] As a preferred embodiment of this utility model, a spring is fixedly connected to the lower side of the sliding plate and the limiting plate, and the lower end of the spring is fixedly connected to the bottom of the inner wall of the limiting block. The spring is used to increase the return capability of the synchronization plate.

[0011] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to the surface of the straw, and spring plates are fixedly connected to the front and rear sides of the top of the fixing plate. The upper side of the spring plate contacts the lower side of the lower flip plate. The spring plate is used to squeeze the lower flip plate to continuously flip upward, so as to ensure that the lower flip plate will not fall accidentally during normal use and affect the leak-proof effect.

[0012] As a preferred embodiment of this utility model, the left side of the lower flap is provided with a rounded corner, which is used to prevent its sharp edges from scratching the operator.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

[0014] 2. This utility model, by incorporating an unsealing mechanism, allows operators to easily and quickly release the seal on the pump head outlet by simply pressing the pressure plate, enabling convenient and quick access to the liquid within the bottle. The combined design of the synchronization plate, sliding plate, limiting block, and limiting plate ensures stable transmission and precise control of the pressing action, thereby improving the device's operational performance.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 4 As shown, the shampoo pump head anti-leakage pressing mechanism provided by this utility model includes a bottle body 1, a straw 2 installed on the upper side of the bottle body 1, a pump head 3 installed on the upper side of the straw 2, an anti-leakage mechanism provided on the upper side of the bottle body 1, the anti-leakage mechanism includes a fixed cylinder 4 fixedly connected to the front and rear sides of the pump head 3, a rotating rod 5 slidably connected to the inner wall of the fixed cylinder 4, a lower flap 6 fixedly connected to the left side of the rotating rod 5, a connecting rod 7 fixedly connected to the inner side of the lower flap 6, and a block 8 fixedly connected to the inner side of the connecting rod 7. The block 8 is used to seal the water outlet of the pump head 3, and an unsealing mechanism is provided on the upper side of the bottle body 1.

[0019] refer to Figure 3The unsealing mechanism includes a pressure plate 9 movably connected to the upper side of the lower flip plate 6, a synchronization plate 10 fixedly connected to the right side of the pressure plate 9, a slide plate 11 fixedly connected to the lower side of the synchronization plate 10, a limit block 12 slidably connected to the surface of the slide plate 11, a limit plate 13 slidably connected to the inner wall of the limit block 12, and a limit plate 13 fixedly connected to the right side of the slide plate 11 on the left side.

[0020] As a technical optimization of this utility model, by setting up an unsealing mechanism, the operator can easily release the seal of the pump head 3 outlet by simply pressing the pressure plate 9, allowing convenient and quick use of the liquid in the bottle 1. The combined design of the synchronization plate 10, the sliding plate 11, the limiting block 12, and the limiting plate 13 ensures stable transmission and precise control of the pressing action, improving the operational performance of the device.

[0021] refer to Figure 3 A septum 14 is fixedly connected to the right side of the plug 8. The septum 14 cooperates with the plug 8 to more effectively seal the outlet of the pump head 3.

[0022] As a technical optimization of this utility model, by setting the septum 14, the outlet of the pump head 3 can be sealed more effectively. The septum 14 can fill the tiny gaps that may exist between the block 8 and the outlet, enhance the sealing effect, further prevent liquid leakage, and improve the sealing reliability of the device.

[0023] refer to Figure 4 A spring 15 is fixedly connected to the lower side of the slide plate 11 and the limiting plate 13. The lower end of the spring 15 is fixedly connected to the bottom of the inner wall of the limiting block 12. The spring 15 is used to increase the return capability of the synchronous plate 10.

[0024] As a technical optimization of this utility model, by setting a spring 15, after the pressure plate 9 is released, the spring force can be used to quickly return the synchronous plate 10, pressure plate 9, and other components to their initial sealed state. The design of spring 15 increases the return capability of synchronous plate 10, ensuring that the device can automatically reset after use, thus improving the convenience of use and the stability of the device.

[0025] refer to Figure 3 A fixing plate 16 is fixedly connected to the surface of the straw 2. A spring plate 17 is fixedly connected to the front and rear sides of the top of the fixing plate 16. The upper side of the spring plate 17 contacts the lower side of the lower flip plate 6. The spring plate 17 is used to squeeze the lower flip plate 6 to continuously flip upward, so as to ensure that the lower flip plate 6 will not fall accidentally during normal use and affect the leak-proof effect.

[0026] As a technical optimization of this utility model, by setting the spring plate 17, the lower flap 6 can be squeezed and continuously flipped upward. This design can ensure that during normal use, the lower flap 6 will not fall unexpectedly due to external factors (such as vibration, collision, etc.), thereby ensuring that the block 8 and the septum 14 always tightly seal the outlet of the pump head 3, effectively maintaining the leak-proof effect of the device.

[0027] refer to Figure 1 The left side of the lower flip plate 6 is provided with a rounded corner 18, which is used to prevent its sharp edges from scratching the operator.

[0028] As a technical optimization of this utility model, the rounded corners 18 prevent sharp edges from scratching operators. During operation, operators may accidentally touch the lower flap 6; the rounded corners 18 improve the safety of the device, reduce accidental injuries, and embody a human-centered design philosophy.

[0029] The working principle and usage process of this utility model are as follows: During use, press down on the pressure plate 9. The pressure plate 9 drives the synchronous plate 10 downwards. The synchronous plate 10 causes the sliding plate 11 to slide downwards inside the limiting block 12. Simultaneously, the limiting plate 13 also moves downwards within the limiting block 12 and compresses the spring 15. As the pressure plate 9 presses down, the lower flip plate 6 flips downwards around the rotating rod 5, causing the block 8 and the septum 14 to leave the outlet of the pump head 3, releasing the seal. At this time, liquid can be drawn from the bottle body 1 through the pump head 3. After use, release the pressure plate 9. The spring 15 returns to its original shape, pushing the limiting plate 13 and the sliding plate 11 upwards, causing the synchronous plate 10 and the pressure plate 9 to return to their original positions. The spring plate 17 presses the lower flip plate 6, causing it to flip upwards continuously, so that the block 8 and the septum 14 reseal the outlet of the pump head 3, preventing liquid leakage. This avoids the desktop contamination caused by easy leakage after pressing the shampoo pump head 3, making it easy to use.

[0030] In summary, when this utility model is used, the anti-leakage mechanism and the unsealing mechanism can seal the outlet of the shampoo pump head 3 after it has been pressed and used, thus avoiding the tabletop pollution caused by easy leakage after the shampoo pump head 3 has been pressed and used, and making it easy to use.
