Description

Technical Field

[0001] This utility model relates to the field of liquid dispenser technology, specifically a height adjustment mechanism for a liquid dispenser device. Background Technology

[0002] Liquid dispensing devices are common equipment used in daily life to facilitate the convenient dispensing of fluids. They are widely used in homes, personal care, kitchens and other scenarios. Their core function is to dispense liquid or paste-like media such as laundry detergent, dish soap, hand soap, and skin care products from storage containers such as bottles and jars as needed, so as to meet people's needs for precise control of liquid volume and convenient operation in cleaning, skin care, cooking and other scenarios.

[0003] Existing liquid dispensing devices typically have a clamping mechanism to secure the liquid bottle, ensuring its stability during use and facilitating dispensing. However, in practice, liquid bottles vary in height, and the clamping mechanism is often fixed to the dispensing device, making it difficult to adjust to different bottle heights. This results in poor compatibility between the dispensing device and the liquid bottle, severely impacting the user experience.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] The existing liquid dispensing devices mentioned above typically include a clamping mechanism to ensure the stability of the liquid bottle during use. However, in actual use, due to the varying heights of liquid bottles, and the fact that the clamping mechanism is often fixedly mounted on the dispensing device, the clamping mechanism struggles to adapt to liquid bottles of different heights, resulting in poor compatibility between the dispensing device and the liquid bottle. The technical solution adopted by this utility model to solve this problem is as follows: A height adjustment mechanism for a liquid dispensing device includes a main housing and a clamping assembly for fixing a liquid bottle. A height adjustment assembly is provided between the main housing and the clamping assembly. The height adjustment assembly includes a swing member, which is hinged to the main housing and engages with the clamping assembly. When the swing member is rotated under force, it locks or unlocks the clamping assembly, allowing the clamping assembly to move vertically relative to the main housing.

[0006] Furthermore, the main housing includes a mounting housing, and the height adjustment assembly includes a hinge shaft and a torsion spring. The hinge shaft is disposed on the mounting housing, and the swing member is hinged to the mounting housing through the hinge shaft. The torsion spring is sleeved on the outer wall of the hinge shaft, one side of the torsion spring abuts against the swing member, and the other side of the torsion spring abuts against the inner wall of the mounting housing.

[0007] Furthermore, the swinging component includes a hook portion, the hook portion having a plurality of teeth spaced apart in the vertical direction, and the clamping assembly having a snap-fit ​​portion that engages with the teeth.

[0008] Furthermore, a snap-fit ​​groove is formed between adjacent snap-fit ​​teeth. The snap-fit ​​groove includes a first snap-fit ​​surface extending in a horizontal direction and a second snap-fit ​​surface inclined relative to the first snap-fit ​​surface. The snap-fit ​​portion includes a first mating surface abutting against the first snap-fit ​​surface and a second mating surface connected to the second snap-fit ​​surface. The second snap-fit ​​surface is inclined upward in a vertical direction.

[0009] Furthermore, the snap-fit ​​groove includes a third snap-fit ​​surface arranged vertically and located between the first snap-fit ​​surface and the second snap-fit ​​surface. The second snap-fit ​​surface extends upward at an incline from the third snap-fit ​​surface toward the opening of the snap-fit ​​groove. The first mating surface and the second mating surface are connected at an incline and have rounded corners.

[0010] Furthermore, the mounting housing includes a mounting opening communicating with the outside, and the swing member includes an operating part that extends to the outside of the mounting housing through the mounting opening.

[0011] Furthermore, a sliding mechanism is provided between the main body housing and the clamping assembly, the sliding mechanism being used to guide the clamping assembly to move relative to the main body housing in a vertical direction.

[0012] Furthermore, the sliding mechanism includes a slide rail disposed on the main housing and a slide groove disposed on the clamping assembly and slidingly engaging with the slide rail.

[0013] Furthermore, the main housing includes a limiting opening for restricting the vertical movement of the clamping assembly, and the clamping assembly passes through the limiting opening to be snapped into the swing member.

[0014] Furthermore, the swing component is integrally formed.

[0015] The beneficial effects of this utility model are as follows: This invention features a height adjustment component between the main body housing and the clamping assembly. The height adjustment component includes a swinging member hinged to the main body housing and engaging with the clamping assembly. When the user moves the swinging member, it rotates under force, unlocking the clamping assembly and allowing it to move vertically relative to the main body housing. This adapts to liquid bottles of varying heights, improving the flexibility of the dispensing device. It effectively solves the problem that existing dispensing devices typically have clamping mechanisms to ensure the stability of the liquid bottle during use. However, in practice, due to differences in liquid bottle heights, and the fact that clamping mechanisms are often fixed to the dispensing device, the clamping mechanism struggles to adapt to different heights, resulting in poor compatibility between the dispensing device and the liquid bottle.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1 to 7The illustrated height adjustment mechanism for a liquid dispensing device includes a main housing 1 and a clamping assembly 2 for fixing a liquid bottle. A height adjustment assembly is provided between the main housing 1 and the clamping assembly 2. The height adjustment assembly includes a swing member 31, which is hinged to the main housing 1 and engages with the clamping assembly 2. When the swing member 31 is rotated under force, it locks or unlocks the clamping assembly 2, allowing the clamping assembly 2 to move vertically relative to the main housing 1. This invention features a height adjustment component between the main body housing and the clamping assembly. The height adjustment component includes a swinging member hinged to the main body housing and engaging with the clamping assembly. When the user moves the swinging member, it rotates under force, unlocking the clamping assembly and allowing it to move vertically relative to the main body housing. This adapts to liquid bottles of varying heights, improving the flexibility of the dispensing device. It effectively solves the problem that existing dispensing devices typically have clamping mechanisms to ensure the stability of the liquid bottle during use. However, in practice, due to differences in liquid bottle heights, and the fact that clamping mechanisms are often fixed to the dispensing device, the clamping mechanism struggles to adapt to different heights, resulting in poor compatibility between the dispensing device and the liquid bottle.

[0020] Furthermore, the swing member 31 is hinged to the main body housing 1 and snapped into the clamping component 2. This allows the user to quickly lock or unlock the clamping component 2 by simply applying force to the swing member 31 to rotate it when the user needs to adjust the relative height of the clamping component 2. No complicated disassembly or assembly steps are required, and the user can easily adjust the height of the clamping component 2, which helps to improve operating efficiency.

[0021] Optionally, in some embodiments, the height adjustment component includes a rack disposed within the main housing 1 and arranged vertically, a gear disposed on the clamping component 2 and meshing with the rack, and a swing member 31. The swing member 31 is hinged to the main housing 1, with one side of the swing member 31 being an exposed actuating end and the other side being a locking pin end. A torsion spring 33 is provided at the hinge point between the swing member 31 and the main housing 1. In its natural state, the torsion spring 33 causes the locking pin to insert into the tooth groove of the gear, and the diameter of the locking pin is adapted to the width of the gear tooth groove. When the height needs to be adjusted, the user moves the actuating end of the swing member 31 outward, causing the swing member 31 to rotate around the hinge point and compress the torsion spring 33. The locking pin disengages from the tooth groove of the current gear, pushing the clamping component 2 to make the gear roll along the rack, thereby moving the clamping component 2 to the target height. After releasing the actuating end, the torsion spring 33 releases its elastic force, causing the swing member 31 to rotate in the opposite direction, and the locking pin automatically inserts into the tooth groove of the current gear, thereby achieving height locking of the clamping component 2.

[0022] Optionally, in some embodiments, the height adjustment assembly includes a screw arranged vertically and a swing member 31. The screw is threadedly connected to the main body housing 1 and fixedly connected to the clamping assembly 2. The swing member 31 is a crank handle, which is coaxially connected to one end of the screw. The screw has multiple positioning holes, and the main body housing 1 has a corresponding pin that can be inserted into the positioning holes. When the height needs to be adjusted, the pin on the main body housing 1 is first pulled out to disengage it from the positioning hole of the screw, and then the crank handle, which is the swing member 31, is rotated. The crank handle drives the coaxial screw to rotate. Since the screw and the main body housing 1 are threaded together, the screw will move up and down along its own axis when it rotates, thereby driving the clamping assembly 2, which is fixedly connected to it, to move vertically in sync. When the clamping assembly 2 moves to the height suitable for the liquid bottle, the crank handle is stopped, and the pin on the main body housing 1 is inserted into the positioning hole at the corresponding position of the screw to lock the rotation and movement of the screw, thereby fixing the height of the clamping assembly 2.

[0023] Furthermore, as a preferred embodiment of this utility model, and not a limitation thereof, the height adjustment assembly includes a hinge shaft 32 and a torsion spring 33. The swing member 31 is hinged to the main body housing 1 via the hinge shaft 32. The torsion spring 33 is sleeved on the outer wall of the hinge shaft 32. One side of the torsion spring 33 abuts against the swing member 31, and the other side of the torsion spring 33 abuts against the inner wall of the main body housing 1. The clamping assembly 2 is provided with a snap-fit ​​part 21, and one side of the swing member 31 is provided with a hook part 311 that is snapped into the snap-fit ​​part 21. When it is necessary to adjust the height of the clamping assembly 2, the swing member 31 is pushed in a specific direction, and the swing member 31 rotates around the main body housing 1. As the hinge shaft 32 rotates, the torsion spring 33 fitted on the outer wall of the hinge shaft 32 is compressed, and the side of the spring that abuts against the swing member 31 is subjected to force. At the same time, the hook part 311 on the swing member 31 disengages from the locking part 21 of the clamping assembly 2 as it rotates, releasing the latch lock. At this time, the clamping assembly 2 can be pushed to move vertically to the height suitable for the liquid bottle. After it moves into place, the swing member 31 is released, the torsion spring 33 releases its elastic force, and pushes the swing member 31 to rotate in the opposite direction around the hinge shaft 32 until the hook part 311 of the swing member 31 re-engages with the locking part 21 of the clamping assembly 2, thereby locking the height of the clamping assembly 2.

[0024] like Figures 1 to 7 The main housing 1 shown includes a mounting housing 11. The height adjustment assembly includes a hinge shaft 32 and a torsion spring 33. The hinge shaft 32 is disposed on the mounting housing 11. The swing member 31 is hinged to the mounting housing 11 through the hinge shaft 32. The torsion spring 33 is sleeved on the outer side wall of the hinge shaft 32. One side of the torsion spring 33 abuts against the swing member 31, and the other side of the torsion spring 33 abuts against the inner side wall of the mounting housing 11. Furthermore, the hinge shaft 32 is disposed on the mounting housing 11 of the main housing 1, and the swing member 31 is hinged to the mounting housing 11 through the hinge shaft 32. The mounting housing 11 can provide stable support for the hinge shaft 32, preventing the swing member 31 from rotating and shifting due to the hinge shaft 32 shaking under force, which helps to ensure the structural stability of the height adjustment assembly.

[0025] Furthermore, the torsion spring 33 is sleeved on the outer wall of the hinge shaft 32, and the two sides of the torsion spring 33 abut against the swing member 31 and the inner wall of the mounting housing 11 respectively, so that the elastic force of the torsion spring 33 acts precisely between the two, which helps to ensure that when the torsion spring 33 is compressed or reset, it can stably push the swing member 31 to rotate around the hinge shaft 32, and avoid the misalignment of the torsion spring 33 causing the buckle engagement between the hook part 311 and the buckle part 21 to fail.

[0026] Furthermore, the mounting housing 11 can provide enclosed protection for internal components such as the hinge shaft 32 and torsion spring 33, which helps reduce the corrosion of components by dust, liquids and other impurities and helps extend the service life of the height adjustment assembly. At the same time, the centralized installation layout makes the overall structure of the height adjustment assembly more regular, which facilitates subsequent assembly, inspection and maintenance operations.

[0027] like Figures 1 to 7 The swing member 31 shown includes a hook portion 311, the hook portion 311 is provided with a plurality of teeth 3111 spaced apart in the vertical direction, and the clamping assembly 2 is provided with a snap-fit ​​portion 21 that engages with the teeth 3111. Furthermore, the hook portion 311 is provided with multiple teeth 3111 distributed vertically at intervals. The multiple teeth 3111 can form a multi-position snap-fit ​​with the snap-fit ​​portion 21 of the clamping component 2. The user can select the corresponding tooth and snap-fit ​​portion to lock according to the different heights of the liquid bottle. Compared with a single tooth setting, it can adapt to more liquid bottles of different heights, which is beneficial to improving the adaptability and flexibility of the liquid dispensing device.

[0028] Furthermore, the locking part 21 and the locking tooth 3111 are multi-point locking and engaging structures. When locked, the locking part 21 can form a tight engagement with the locking tooth 3111, and the adjacent locking teeth 3111 can provide certain limiting support for the locking part 21. This helps to reduce the risk of the locking part loosening due to vibration or external force during use, and helps to ensure that the clamping component 2 is not easily displaced after being fixed, effectively improving the stability of the liquid bottle after installation.

[0029] Furthermore, the user only needs to move the swing member 31 to separate the locking teeth 3111 from the locking part 21, then adjust the height of the clamping component 2, and then release the swing member 31 so that the locking teeth 3111 can re-engage with the locking part 21, thus completing the height adjustment of the clamping component 2. No complicated tools or steps are required, which helps to improve the efficiency of use.

[0030] like Figures 1 to 7 A locking groove 3112 is formed between adjacent locking teeth 3111. The locking groove 3112 includes a first locking surface 301 extending in the horizontal direction and a second locking surface 302 inclined relative to the first locking surface 301. The locking part 21 includes a first mating surface 211 abutting against the first locking surface 301 and a second mating surface 212 connected to the second locking surface 302. The second locking surface 302 is inclined upward in the vertical direction. Furthermore, the second engaging surface 302 of the engaging groove 3112 is inclined upward in the vertical direction and is adapted to the second mating surface 212 of the engaging part 21. When the clamping component 2 is adjusted upward, the second mating surface 212 can slide smoothly along the inclined second engaging surface 302. With the guiding effect of the inclined surface, the clamping component 2 can be pushed upward without additionally moving the swinging component 31, which helps to reduce adjustment steps and improve the ease of operation.

[0031] Furthermore, the first engaging surface 301 of the engaging groove 3112 extends horizontally and abuts against the first mating surface 211 of the engaging part 21. When the clamping component 2 tends to move downward due to the weight of the liquid bottle or external force, the horizontal first engaging surface 301 can form a rigid block against the first mating surface 211, preventing the engaging part 21 from sliding down. Compared with the inclined surface mating, the force on the horizontal contact surface is more uniform, which is conducive to improving the locking stability in the downward direction and helps to ensure that the clamping component 2 is not easy to move downward after it is fixed.

[0032] Specifically, when it is necessary to adjust the clamping component 2 upward, the user can choose two operating methods. The first method is to push the clamping component 2 upward by disengaging the locking mechanism 31. The second method is to directly push the clamping component 2 upward. In this case, the second mating surface 212 of the locking part 21 slides smoothly along the second locking surface 302 of the locking groove 3112, which is inclined upward. The upward movement can be completed without disengaging the locking mechanism 31 by means of the inclined surface. However, when it is necessary to adjust the clamping component 2 downward, since the first locking surface 301 of the locking groove 3112 is horizontal, it will form a rigid block on the first mating surface 211 of the locking part 21, and it cannot be directly pushed downward. The user can only push the clamping component 2 downward by disengaging the locking hook 311 from the locking part 21 by disengaging the locking mechanism 31.

[0033] like Figures 1 to 7 The snap-fit ​​groove 3112 shown includes a third snap-fit ​​surface 303 arranged vertically and located between the first snap-fit ​​surface 301 and the second snap-fit ​​surface 302. The second snap-fit ​​surface 302 extends upward at an incline from the third snap-fit ​​surface 303 toward the opening of the snap-fit ​​groove 3112. The first mating surface 211 and the second mating surface 212 are connected at an incline and have rounded corners. Furthermore, the first mating surface 211 and the second mating surface 212 are inclined and rounded, which helps to eliminate sharp edges at the joint of the mating surfaces, reduces frictional wear between surfaces during adjustment, and effectively extends the service life of the component. Secondly, the rounded corners help to expand the contact tolerance range of the mating surfaces. Even if there is a slight misalignment between the locking part 21 and the locking groove 3112 during adjustment, the rounded corners can guide the two to fit smoothly, which helps to reduce the accuracy requirements of operation and effectively improves the user's tolerance for errors.

[0034] Furthermore, the third locking surface 303 is arranged vertically and forms a vertical connection with the horizontal first locking surface 301, which can provide auxiliary limiting for the side of the locking part 21 and prevent the locking part 21 from shifting in the horizontal direction when locking downwards; secondly, the contact between the first mating surface 211 and the first locking surface 301 is more stable, and the rounded corners protect the mating surface, which helps to reduce the locking loosening caused by component wear after long-term use, ensuring the reliability of downward locking, and further adapting to the adjustment operation that can only be unlocked and moved downwards by tossing the swing member 31.

[0035] Furthermore, the third snap-fit ​​surface 303 serves as a transitional support surface between the first snap-fit ​​surface 301 and the second snap-fit ​​surface 302, so that the snap-fit ​​part 21 is subjected to more uniform force in the locked state, avoiding stress concentration at the root of the inclined surface, which is beneficial to enhancing structural strength and durability and effectively extending service life.

[0036] like Figures 1 to 7 The mounting housing 11 shown includes a mounting opening 111 communicating with the outside, and the swing member 31 includes an operating part 312, which extends to the outside of the mounting housing 11 through the mounting opening 111. Furthermore, the operating part 312 of the swing member 31 extends to the outside through the mounting opening 111 of the mounting housing 11. The user can directly contact the operating part 312 without disassembling the mounting housing 11. Whether it is toggling to unlock when adjusting upwards or toggling to unlock when adjusting downwards, the operation can be quickly completed through the external operating part 312. This helps to avoid the inconvenience of adjustment caused by the operating part 312 being hidden inside the housing and helps to reduce the difficulty of operation for the user.

[0037] Furthermore, the mounting opening 111 only allows the operating part 312 to extend to the outside, preventing dust, liquid and other impurities from entering the interior due to the complete opening of the mounting housing 11. This provides effective protection for core components such as the hinge shaft 32 and torsion spring 33, which helps to extend the service life of the components. Secondly, the exposure of the operating part through the mounting opening 111 helps to meet the user's operating needs for the swing component 31, and helps to balance protection and operability.

[0038] like Figures 1 to 7A sliding mechanism is provided between the main body housing 1 and the clamping assembly 2 shown, the sliding mechanism being used to guide the clamping assembly 2 to move relative to the main body housing 1 in a vertical direction; Furthermore, the sliding mechanism can provide clear guidance for the vertical movement of the clamping component 2, restricting the horizontal offset or rotation of the clamping component 2 during the adjustment process, and avoiding the situation where the locking part 21 and the locking tooth 3111 are misaligned or cannot be successfully locked due to deviation in the direction of movement, which helps to ensure the accuracy of height adjustment.

[0039] Furthermore, the sliding mechanism is designed to make the contact between the clamping component 2 and the main housing 1 more uniform, which helps to reduce the possibility of excessive local wear, extends the service life of the components, and effectively improves the durability of the entire device.

[0040] Optionally, in some embodiments, the sliding mechanism includes a vertical guide post fixed to the main body housing 1, a ball sleeve sleeved around the outer periphery of the guide post, and a connecting seat fixedly connected to the ball sleeve sleeve. The connecting seat is connected to the clamping assembly 2. When the clamping assembly 2 is raised or lowered, the ball sleeve sleeve slides along the guide post, which helps to reduce frictional resistance.

[0041] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the sliding mechanism includes a slide rail 41 disposed on the main housing 1 and a slide groove 42 disposed on the clamping assembly 2 and slidingly engaged with the slide rail 41.

[0042] like Figures 1 to 7 The sliding mechanism shown includes a slide rail 41 disposed on the main housing 1 and a slide groove 42 disposed on the clamping assembly 2 and slidingly engaged with the slide rail 41; Furthermore, the slide rail 41 and the slide groove 42 form a "convex-concave" nested fit. When the clamping component 2 moves in the vertical direction, the inner wall of the slide groove 42 forms a limiting constraint on the slide rail 41 in the left and right and front and back directions. This helps to ensure that the movement trajectory is straight and stable, and helps to avoid tilting, jamming or misalignment caused by uneven force during adjustment or use, effectively ensuring the stability of the buckle structure.

[0043] Furthermore, the mating surfaces of the slide rail 41 and the slide groove 42 can be treated by grinding, polishing or adding a wear-resistant coating, which helps to reduce the frictional resistance when the two slide, making the up-and-down adjustment of the clamping assembly 2 easier and smoother.

[0044] like Figures 1 to 7 The main housing 1 shown includes a limiting opening 12 for restricting the movement of the clamping assembly 2 in the vertical direction, and the clamping assembly 2 passes through the limiting opening 12 and is snapped into the swing member 31. Furthermore, after the clamping component 2 passes through the limiting opening 12, the upper and lower edges of the limiting opening 12 can serve as the upper and lower limits for the movement of the clamping component 2, respectively. When the clamping component 2 is adjusted upward to its maximum height, its top will abut against the upper edge of the limiting opening 12; when it is adjusted downward to its minimum height, its bottom will abut against the lower edge of the limiting opening 12. This effectively prevents damage to the components due to excessive adjustment and helps ensure the safety of the adjustment process.

[0045] Furthermore, by opening a limiting opening 12 in the main body shell 1 to achieve stroke constraint, it is beneficial to eliminate the need for additional components such as limiting blocks, baffles or sensors required in traditional settings, which helps to reduce the number of parts and assembly complexity, effectively saving costs; at the same time, it helps to reduce failure points and effectively improve the reliability of the device.

[0046] Furthermore, by observing the position of the clamping component 2 relative to the limiting opening 12, users can intuitively determine the current height position and the remaining adjustable range, making the adjustment process more controllable and intuitive, which is conducive to improving the user experience.

[0047] like Figures 1 to 7 The swing component 31 shown is integrally formed; Furthermore, the oscillating component 31 adopts an integral molding design, which helps to eliminate gaps and weak points at the splicing of components. Compared with the split assembly structure, the overall deformation resistance is stronger. Under frequent tossing operations or long-term stress, it helps to avoid functional failure caused by loosening or breakage at the splicing, which helps to extend the service life of the oscillating component 31 and effectively ensures the long-term stable operation of the height adjustment component.

[0048] Furthermore, the one-piece molded swing component 31 does not require subsequent assembly of functional parts such as the hook part 311 and the operating part 312, and can be directly installed with components such as the hinge shaft 32 and the torsion spring 33, which helps to reduce the number of parts and assembly steps.

[0049] Furthermore, the integrally formed swing component 31 helps to ensure the relative positional accuracy of key parts such as the hook part 311, the hinge hole, and the operating part 312, so that the rotation trajectory of the swing component 31 around the hinge axis 32 is stable, and the locking teeth 3111 and the locking part 21 are accurately engaged and aligned, which helps to avoid problems such as jamming, false locking, or unlocking failure caused by misalignment of separate parts.

[0050] The workflow is as follows: When the user needs to adjust the clamping assembly 2 upwards, there are two options: First, manually move the operating part 312 of the swing member 31 to rotate it around the hinge axis 32, causing the hook part 311 to lift up, and the locking teeth 3111 to disengage from the locking part 21. After unlocking, the clamping assembly 2 can be moved upwards. Second, directly push the clamping assembly 2 upwards. At this time, the second mating surface 212 of the locking part 21 slides smoothly along the upwardly inclined second locking surface 302 of the locking groove 3112, guided by the inclined surface. The upward movement can be completed without moving the swinging component 31. When the user needs to adjust downward, because the first locking surface 301 is a horizontal limiting surface and rigidly abuts against the first mating surface 211, the clamping component 2 cannot be pressed down directly. The swinging component 31 must be unlocked before it can move downward. During the entire adjustment process, the sliding mechanism always guides the clamping component 2 to move smoothly in the vertical direction. After the user releases the hand, the torsion spring 33 drives the swinging component 31 to automatically reset, so that the locking teeth 3111 re-engage in the corresponding position to complete the locking.

[0051] The implementation method of Example 1 is as follows: A height adjustment mechanism for a liquid dispensing device includes a main housing 1 and a clamping assembly 2 for fixing a liquid bottle. A height adjustment assembly is provided between the main housing 1 and the clamping assembly 2. The height adjustment assembly includes a swing member 31, which is hinged to the main housing 1 and engages with the clamping assembly 2. When the swing member 31 is rotated under force, it locks or unlocks the clamping assembly 2, so that the clamping assembly 2 can move relative to the main housing 1 in the vertical direction.

[0052] This invention features a height adjustment component between the main body housing and the clamping assembly. The height adjustment component includes a swinging member hinged to the main body housing and engaging with the clamping assembly. When the user moves the swinging member, it rotates under force, unlocking the clamping assembly and allowing it to move vertically relative to the main body housing. This adapts to liquid bottles of varying heights, improving the flexibility of the dispensing device. It effectively solves the problem that existing dispensing devices typically have clamping mechanisms to ensure the stability of the liquid bottle during use. However, in practice, due to differences in liquid bottle heights, and the fact that clamping mechanisms are often fixed to the dispensing device, the clamping mechanism struggles to adapt to different heights, resulting in poor compatibility between the dispensing device and the liquid bottle.

[0053] The implementation method of Example 2 is as follows: Based on Embodiment 1, Embodiment 2 further includes the following implementation: The main housing 1 includes a mounting housing 11, and the height adjustment assembly includes a hinge shaft 32 and a torsion spring 33. The hinge shaft 32 is disposed on the mounting housing 11, and the swing member 31 is hinged to the mounting housing 11 through the hinge shaft 32. The torsion spring 33 is sleeved on the outer wall of the hinge shaft 32, one side of the torsion spring 33 abuts against the swing member 31, and the other side of the torsion spring 33 abuts against the inner wall of the mounting housing 11.

[0054] The implementation method of Example 3 is as follows: Based on Embodiment 1, Embodiment 3 also has the following implementation method: the swing member 31 includes a hook part 311, the hook part 311 is provided with a plurality of teeth 3111 distributed at intervals along the vertical direction, and the clamping component 2 is provided with a snap-fit ​​part 21 that engages with the teeth 3111.

[0055] The implementation method of Example 4 is as follows: Based on Embodiment 3, Embodiment 4 further includes the following implementation: a snap-fit ​​groove 3112 is formed between adjacent snap-fit ​​teeth 3111. The snap-fit ​​groove 3112 includes a first snap-fit ​​surface 301 extending in the horizontal direction and a second snap-fit ​​surface 302 inclined relative to the first snap-fit ​​surface 301. The snap-fit ​​part 21 includes a first mating surface 211 abutting against the first snap-fit ​​surface 301 and a second mating surface 212 connected to the second snap-fit ​​surface 302. The second snap-fit ​​surface 302 is inclined upward in the vertical direction.

[0056] The implementation method of Example 5 is as follows: Based on Embodiment 4, Embodiment 5 further includes the following implementation: The snap-fit ​​groove 3112 includes a third snap-fit ​​surface 303 arranged vertically and located between the first snap-fit ​​surface 301 and the second snap-fit ​​surface 302. The second snap-fit ​​surface 302 extends upward at an incline from the third snap-fit ​​surface 303 toward the opening of the snap-fit ​​groove 3112. The first mating surface 211 and the second mating surface 212 are connected at an incline and have rounded corners.

[0057] The implementation method of Example 6 is as follows: Based on Example 2, Example 6 also has the following implementation: The mounting housing 11 includes a mounting opening 111 communicating with the outside, and the swing member 31 includes an operating part 312, which extends to the outside of the mounting housing 11 through the mounting opening 111.

[0058] The implementation method of Example 7 is as follows: Based on Example 1, Example 7 also has the following implementation method: a sliding mechanism is provided between the main body shell 1 and the clamping assembly 2. The sliding mechanism is used to guide the clamping assembly 2 to move relative to the main body shell 1 in the vertical direction.

[0059] The implementation method of Example 8 is as follows: Based on Embodiment 7, Embodiment 8 further includes the following implementation: the sliding mechanism includes a slide rail 41 disposed on the main housing 1 and a slide groove 42 disposed on the clamping assembly 2 and slidingly engaged with the slide rail 41.

[0060] The implementation method of Example 9 is as follows: Based on Embodiment 1, Embodiment 9 also has the following implementation method: The main body housing 1 includes a limiting opening 12 for restricting the movement of the clamping assembly 2 in the vertical direction, and the clamping assembly 2 passes through the limiting opening 12 and is snapped into connection with the swinging member 31.

[0061] The implementation method of Example 10 is as follows: Based on Example 1, Example 10 also has the following implementation method: the swing component 31 is integrally formed.

[0062] The implementation method of Example 11 is as follows: Example 11, based on Example 1, further includes the following implementation: The height adjustment component includes a rack disposed within the main housing 1 and arranged vertically, a gear disposed on the clamping component 2 and meshing with the rack, and a swing member 31. The swing member 31 is hinged to the main housing 1. One side of the swing member 31 is an exposed actuating end, and the other side is a locking pin end. A torsion spring 33 is provided at the hinge point between the swing member 31 and the main housing 1. In its natural state, the torsion spring 33 causes the locking pin to insert into the tooth groove of the gear. The diameter of the locking pin is adapted to the width of the gear tooth groove. When height adjustment is required, the user moves the actuating end of the swing member 31 outward. The swing member 31 rotates around the hinge point and compresses the torsion spring 33. The locking pin disengages from the tooth groove of the current gear, pushing the clamping component 2 to make the gear roll along the rack, thereby moving the clamping component 2 to the target height. After releasing the actuating end, the torsion spring 33 releases its elastic force, causing the swing member 31 to rotate in the opposite direction. The locking pin automatically inserts into the tooth groove of the current gear, thereby achieving height locking of the clamping component 2.

[0063] The implementation method of Example Twelve is as follows: The difference between Embodiment Twelve and Embodiment Eleven is that the height adjustment component includes a screw arranged vertically and a swinging component 31. The screw is threadedly connected to the main body housing 1 and fixedly connected to the clamping component 2. The swinging component 31 is a crank handle, which is coaxially connected to one end of the screw. The screw has multiple positioning holes, and the main body housing 1 has a corresponding pin that can be inserted into the positioning hole. When the height needs to be adjusted, the pin on the main body housing 1 is first pulled out to disengage it from the positioning hole of the screw, and then the crank handle, which is the swinging component 31, is rotated. The crank handle drives the coaxial screw to rotate. Since the screw and the main body housing 1 are threaded together, the screw will move up and down along its own axis when it rotates, thereby driving the clamping component 2, which is fixedly connected to it, to move vertically in sync. When the clamping component 2 moves to the height suitable for the liquid bottle, the crank handle is stopped, and the pin on the main body housing 1 is inserted into the positioning hole at the corresponding position of the screw to lock the rotation and movement of the screw, thereby fixing the height of the clamping component 2.
