Description

Technical Field

[0001] This utility model relates to the field of press-type pump head technology, specifically to a detachable, washable pump head structure with adjustable sugar output. Background Technology

[0002] In food preparation (such as milk tea and coffee blending), food processing (such as adding baking syrups), and home kitchens, pump heads are often used to precisely dispense viscous liquids such as syrups and honey to ensure convenient addition and consistent dosage. While current liquid pump heads on the market can achieve basic press-and-dispense functionality, the following technical challenges remain to be addressed in practical applications in food-grade settings.

[0003] Most existing pump heads adopt an integrated or semi-integrated structure, with their internal suction channels (such as the piston rod cavity, connecting tube, and suction tube) fixedly connected to external components, making it impossible to independently disassemble the entire assembly. Because viscous liquids such as syrup and honey are prone to adhesion and solidification, liquid residue easily remains in the dead corners of the pump head's internal channels after use (such as the folds in the connecting tube, the gap between the piston rod and the suction tube, and the connection point to the outlet). The enclosed internal structure prevents users from thoroughly cleaning the residual liquid—they can only rinse the outside of the pump head or the outlet, unable to reach the internal residue areas.

[0004] Prolonged use can lead to the growth of bacteria and mold in the residual viscous liquid, or it may solidify into lumps due to water evaporation. This can not only cause pump head blockage and poor liquid flow, but also potentially lead to liquid deterioration (such as syrup turning sour or microbial growth), violating the hygiene standards for food-grade utensils and posing a potential threat to the health of users. Especially in the catering industry, such hygiene hazards can lead to food safety issues, affecting product quality and consumer trust. Utility Model Content

[0005] The purpose of this invention is to provide a detachable, washable pump head structure with adjustable sugar output, in order to solve the problem that the pump head structure in the prior art is inconvenient to disassemble and clean.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable and washable pump head structure with adjustable sugar output, including a pump body, wherein the pump body is provided with a disassembly component and an adjustment component;

[0007] The disassembly assembly includes a pusher head, a liquid outlet at one bottom end of the pusher head, a connecting tube installed at the liquid outlet, a piston rod installed at the bottom of the other side of the pusher head, a locking cap and a bottle cap fitted on the piston rod, a straw at the bottom end of the piston rod, a threaded interface at the top end of the straw, a spring inside the straw, and an inner plug installed at the bottom end of the spring.

[0008] The adjustment assembly includes a C-shaped buckle, a limit plate is installed at the bottom end of the piston rod, and a sealing plate is movably sleeved on the piston rod.

[0009] Furthermore, one end of the connecting pipe is installed on the liquid outlet, and the other end of the connecting pipe is installed on the piston rod.

[0010] Furthermore, the locking cap is disposed on the top of the bottle cap, and the locking cap is installed on the threaded interface.

[0011] Furthermore, the end of the piston rod is movably inserted into the inside of the straw, and the C-shaped buckle is engaged at the bottom end of the piston rod.

[0012] Furthermore, the C-shaped buckle and the sealing plate are both located on the top of the limiting plate, and the C-shaped buckle and the sealing plate are both located below the locking cover.

[0013] Furthermore, the bottle cap is fitted onto the top of the straw, and the sealing plate is positioned at the top of the spring.

[0014] Compared with the prior art, the advantages of the detachable, washable, and adjustable sugar output pump head structure provided by this utility model are as follows:

[0015] 1. Through the modular design of disassembly components (the pump head, connecting tube, piston rod, straw, etc. can all be disassembled independently), the problem of closed internal channels and many dead corners in traditional pump heads is solved: simply unscrew the locking cap to separate the piston rod and straw. After further disassembling each component, it can be directly rinsed with water, sterilized at high temperature, or adapted to a sterilizer to effectively remove syrup residue (especially the inner wall of the connecting tube and the inner cavity of the piston rod where viscous liquids are easy to adhere), avoid bacterial growth or deterioration of residual liquid, and meet the hygiene standards of food-grade utensils;

[0016] 2. The adjustment component achieves flexible control of sugar output through a dual adjustment logic of C-shaped buckle position adjustment and multi-size buckle replacement: On the one hand, the C-shaped buckle can slide up and down along the piston rod, directly limiting the piston rod's downward stroke by changing the relative distance with the sealing plate (the stroke determines the single output volume); on the other hand, C-shaped buckle accessories of different lengths can further expand the adjustment range (such as the subdivided needs from slightly sweet, half sweet to full sweet), solving the problem of fixed output volume or low adjustment accuracy of traditional pump heads, especially suitable for scenarios such as milk tea shops and bakeries that have strict requirements on the amount of syrup used.

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] Example 1:

[0027] This utility model provides a detachable and washable pump head structure with adjustable sugar output, including a pump body 1, on which a disassembly component 2 and an adjustment component 3 are provided;

[0028] The disassembly assembly 2 includes a push-button 21 (the push-button 21 adopts an ergonomic arc design with a smooth and rounded top contact surface, making it easy for the user to apply pressure. Its bottom sides are connected to a liquid outlet 22 and a piston rod 24, forming a linkage mechanism of pressing action – force transmission – liquid output. When pressed, it synchronously drives the piston rod 24 downwards, and returns to its original position with the spring 29 after release). One end of the push-button 21 has a liquid outlet 22 (the liquid outlet 22 adopts an inclined tubular structure, with an end diameter typically 3-5mm designed according to the liquid output requirements, reducing liquid residue and preventing dripping. Its inner wall is polished to reduce the probability of adhesion of viscous liquids such as syrup). A connecting tube 2 is installed on the liquid outlet 22. 3. The connecting tube 23 is a flexible or rigid conduit (preferably made of food-grade silicone, resistant to sugar solution corrosion). Its two ends are respectively sealed to the liquid outlet 22 and the piston rod 24 to form a liquid delivery channel. Its interior is hollow and the tube diameter is uniform to ensure that the liquid flows smoothly under pressure and avoids blockage caused by sudden changes in tube diameter. The piston rod 24 is installed on the bottom of the other side of the push head 21 (the piston rod 24 adopts a hollow columnar structure, preferably made of food-grade PP or PE. Its top end is fixedly connected to the push head 21, and its bottom end is movably inserted into the straw 27 and can slide up and down along the axial direction of the straw 27). One end of the connecting tube 23 is installed on the liquid outlet 22, and the other end of the connecting tube 23 is installed on the piston rod 24.

[0029] The piston rod 24 is fitted with a locking cap 25 (the locking cap 25 is a ring structure with internal threads, which, by screwing into the threaded interface 28 at the top of the straw 27, fixes the piston rod 24 and the straw 27 together, while enhancing the sealing of the connection between the two to prevent liquid leakage; its outer surface has anti-slip textures for easy manual unscrewing and disassembly) and a bottle cap 26 (the bottle cap 26 is fitted below the locking cap 25 and is connected to the mouth of a container such as a syrup bottle by threads or snaps, fixing the entire pump head in place). To prevent the pump head from shaking or falling off during use and further enhance the sealing effect, a locking cap 25 is located on top of the bottle cap 26. A straw 27 is located at the bottom of the piston rod 24 (the straw 27 is a long, thin tubular structure extending to the bottom of the container; its material is the same as the piston rod 24 to ensure food safety; its interior is hollow, serving both as a sliding track for the piston rod 24 and as a channel for liquid to enter the pump head from the container). The end of the piston rod 24 is movably inserted into the straw 27. The top is provided with a threaded interface 28, and a locking cap 25 is installed on the threaded interface 28. A spring 29 (made of food-grade stainless steel, vertically installed inside the straw 27, with its top end abutting against the bottom of the piston rod 24 and its bottom end connected to an inner plug 210; its elasticity parameters have been optimized to ensure effortless pressing and smooth return, avoiding insufficient liquid intake due to insufficient elasticity) is installed at the bottom of the spring 29. The inner plug 210 (conical or spherical) is installed at the bottom of the spring 29. The sealing element, preferably made of food-grade silicone, is elastic and has strong sealing performance. It is installed at the bottom outlet of the straw 27. When pressed, the inner plug 210 tightly fits the outlet of the straw 27 under the pressure of the piston rod 24 moving downward, blocking the connection between the container and the straw 27 and ensuring that the liquid in the pump head can only be discharged through the connecting pipe 23. When returning to its original position, the inner plug 210 separates from the outlet under the negative pressure inside the straw 27, allowing the liquid in the container to enter the piston rod 24 through the straw 27, thus completing the liquid suction.

[0030] Working principle: Liquid discharge process:

[0031] When the press head 21 is pressed, the press head 21 drives the piston rod 24 to move downward. The bottom end of the piston rod 24 moves down along the inside of the straw 27, compressing the spring 29 inside the straw 27. At this time, the inner plug 210 at the bottom of the straw 27 is tightly closed under pressure, blocking the communication between the straw 27 and the inside of the container. At the same time, the liquid (or syrup) inside the piston rod 24 is squeezed and discharged from the liquid outlet 22 through the connecting tube 23, completing one liquid dispensing action.

[0032] The process of repositioning and liquid aspiration:

[0033] After the push button 21 is released, the compressed spring 29 releases its elasticity, pushing the piston rod 24 upward to reset. At this time, a negative pressure is formed inside the straw 27 due to the upward movement of the piston rod 24. The inner plug 210 is opened by the negative pressure, and the liquid (or syrup) in the container is drawn into the piston rod 24 through the straw 27, preparing for the next press to dispense liquid.

[0034] The detachable cleaning function is achieved as follows:

[0035] When cleaning is required, the locking cover 25 is connected to the straw 27 via the threaded interface 28. The locking cover 25 can be unscrewed to separate the piston rod 24 from the straw 27. At the same time, the push head 21, connecting tube 23, piston rod 24, straw 27 and other components can be disassembled independently, which facilitates thorough cleaning of the internal parts of each component and avoids liquid residue blockage or contamination.

[0036] Example 2:

[0037] This embodiment is basically the same as the previous embodiment, except that the adjusting component 3 includes a C-shaped buckle 31 (the C-shaped buckle 31 is made of food-grade elastic plastic, and has an overall "C"-shaped open ring structure with an opening width slightly smaller than the diameter of the piston rod 24. Its inner side has anti-slip teeth, which fit tightly against the outer surface of the piston rod 24. It achieves a detachable snap-fit ​​through its own elasticity, ensuring that it will not slide freely during pressing and can be easily removed by manually prying open the opening. The C-shaped buckle 31 is set in different sizes; by replacing the C-shaped buckle 31 with different sizes, its relative distance to the sealing plate 33 is changed, thereby limiting the downward stroke of the piston rod 24 and controlling the sugar output). The C-shaped buckle 31 is snapped onto the bottom end of the piston rod 24, and a limiting plate 32 is installed at the bottom end of the piston rod 24 (the limiting plate 32 is a circular thin sheet structure, made of the same food-grade material as the piston rod 24, and is welded or integrally formed). The molding process is fixed at the bottom of the piston rod 24. Its diameter is larger than the inner diameter of the C-shaped buckle 31 and the center hole diameter of the sealing plate 33, forming a physical barrier. It mainly plays a dual protection role, preventing the C-shaped buckle 31 and the sealing plate 33 from sliding off the bottom of the piston rod 24 and ensuring the structural integrity of the adjustment component 3. The sealing plate 33 is movably sleeved on the piston rod 24 (the sealing plate 33 is a circular flat plate structure, preferably made of food-grade silicone, which has both elasticity and sealing properties. It has a through hole in the center that matches the diameter of the piston rod 24. It is installed on the piston rod 24 in a movable sleeve manner and can float slightly up and down with the movement of the piston rod 24, but its overall position is relatively stable due to the restriction of the locking cover 25 and the spring 29). The C-shaped buckle 31 and the sealing plate 33 are both located on the top of the limiting plate 32, and both are located below the locking cover 25. The sealing plate 33 is located at the top of the spring 29.

[0038] Working principle: Basic liquid discharge and return process:

[0039] Consistent with Example 1: When the pusher 21 is pressed, the piston rod 24 moves down to compress the spring 29, the inner plug 210 closes, and the liquid is discharged from the outlet 22 through the connecting pipe 23; after the pusher 21 is released, the spring 29 returns to its original position and pushes the piston rod 24 up, the inner plug 210 opens, and the liquid is drawn into the piston rod 24.

[0040] Principle of sugar yield adjustment:

[0041] Adjustment component 3 controls the single dispensing volume by limiting the downward movement distance of piston rod 24:

[0042] When the C-shaped buckle 31 is engaged with the piston rod 24, the relative distance between it and the sealing plate 33 changes. When the push head 21 is pressed, the piston rod 24 moves downward until the C-shaped buckle 31 touches the sealing plate 33. At this point, the piston rod 24 can no longer move downward. The length of the C-shaped buckle 31 determines the maximum downward stroke of the piston rod 24.

[0043] The longer the stroke, the greater the compression of the spring 29, and the more liquid is discharged from the piston rod 24; the shorter the stroke, the less liquid is discharged. By adjusting and replacing C-shaped clips 31 of different lengths, the amount of sugar dispensed at one time (such as the output of liquids like syrup) can be precisely adjusted.

[0044] The sealing plate 33 is movably sleeved on the piston rod 24, which does not affect the up and down movement of the piston rod 24, and can form a stable support when the C-shaped buckle 31 is in contact. At the same time, it works with the space structure under the locking cover 25 to ensure that liquid does not leak from the gap during the pressing process.

[0045] The limiting plate 32 is installed at the bottom of the piston rod 24 to prevent the C-shaped buckle 31 and the sealing plate 33 from falling off the piston rod 24, thus ensuring the structural stability of the adjusting component 3.

[0046] Each component of the adjustment assembly 3 (C-shaped buckle 31, limiting plate 32, sealing plate 33) is an independently assembled structure. When disassembling, the piston rod 24 can be separated from the suction tube 27 without affecting the disassembly and cleaning of the overall assembly, thus maintaining the easy-to-maintain characteristics of Embodiment 1.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
