Description

Technical Field

[0001] The present invention relates to the technical field of pet products, and in particular to a pet drinking device with a sliding linkage switch mechanism and the ability to automatically open and close a water outlet. Background Art

[0002] As pet ownership continues to increase, traditional mechanical pet drinking water systems are widely used due to their simple structure and low cost. However, these devices suffer from fundamental flaws in the automated control of the water outlet, primarily manifesting in the following three aspects: First, they rely heavily on manual operation, making it impossible to switch between the unfolded and folded storage modes while also enabling the water filling channel to open and close autonomously. Mainstream gravity-operated water bottles rely on cumbersome operation and lack a sliding, linked switch mechanism, resulting in numerous and complex manual steps. Existing gravity-operated water bottles with foldable water trays operate independently of the unfolded and water filling modes, making it impossible to link the unfolded and water filling modes. Second, mechanical seals lack reliability and present a risk of leakage. While existing float-valve-controlled devices can achieve liquid level sensing, their sealing structure has inherent flaws: prolonged immersion in the float linkage can lead to scale buildup, preventing the float from fully resetting; and the sealing rubber ring can permanently deform after frequent compression, losing its elastic sealing ability. Experiments have shown that conventional float valves have a leakage rate as high as 23% after 2,000 opening and closing cycles. Third, rigid structures lead to conflicts between hygiene and space. Fixed drinking water trays are exposed to the air for long periods of time, allowing pollutants such as pet hair and dust to fall directly into the water, breeding bacteria at a rate more than four times faster than in closed structures. While removable and cleanable water trays can improve hygiene, the water outlet must be manually closed each time it is cleaned (such as by tightening the lid or unplugging the water pipe), which is cumbersome and relies on manual intervention. Some products have attempted to use foldable water trays to save space, but the water outlet still cannot be closed when folded, resulting in the water tank being continuously exposed to the air and accelerating water quality deterioration.

[0003] In summary, developing a mechanical drinking water device that achieves a self-locking water outlet and provides sanitary protection has become a technical bottleneck in the pet product industry that urgently needs to be overcome. To this end, the present invention provides a pet water bottle based on a sliding mechanical linkage, which completely solves this problem through an innovative spring-butt block transmission mechanism. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides a pet water bottle with a sliding linkage switch mechanism that can automatically open and close the water outlet. It has a simple structure and solves the problem that the water outlet cannot be opened in the unfolded state and cannot be closed in the folded state.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A pet water bottle, used to meet the drinking water needs of pets, comprising:

[0007] The water replenishment assembly includes a bucket body and a water outlet bucket cover, wherein the bucket body is provided with a water outlet bucket opening, and the water outlet bucket cover is used to open or close the water outlet bucket opening;

[0008] The base assembly includes a base body and a pet drinking water tray, wherein the pet drinking water tray is slidably connected to the base body and has an open state and a closed state. The pet drinking water tray can be switched between the closed state and the open state by sliding; when the pet drinking water tray is in the closed state, the water outlet bucket cover automatically closes the water outlet bucket opening; when the pet drinking water tray is in the open state, the water outlet bucket cover automatically opens the water outlet bucket opening.

[0009] As an improvement of the present invention, the water outlet bucket cover is provided with a water sealing plug, an axially movable pin and a spring, the movable pin includes an abutting protrusion, a connecting protrusion and a connecting column, the abutting protrusion and the connecting protrusion are fixedly connected by the connecting column, and the abutting protrusion is located below the connecting protrusion, the connecting protrusion is connected to the water sealing plug, and the water sealing plug is used to seal or clear the water outlet bucket mouth; the water outlet bucket cover is also provided with a mounting through hole for the movable pin to pass through and a bucket cover abutting portion for abutting the spring; the spring is sleeved on the connecting column, its first end abuts the abutting protrusion, and its second end abuts the bucket cover abutting portion. Under normal circumstances, the pet water drinking tray is in the closed state, and the elastic force generated by the spring drives the abutting protrusion to move downward to seal the water outlet bucket mouth.

[0010] As an improvement of the present invention, a drinking tray abutment portion is provided on the pet drinking tray; when the pet drinking tray is in the closed state, the drinking tray abutment portion is separated from the abutment protrusion, and the spring force drives the movable pin to move downward, thereby driving the water sealing plug to move downward through the connecting protrusion to automatically block the water outlet; when the pet drinking tray is in the open state, the drinking tray abutment portion pushes the abutment protrusion to overcome the spring force and move upward, and the movable pin drives the connecting protrusion to move upward through the connecting column, thereby driving the water sealing plug to move upward and away from the water outlet to achieve automatic dredging of the water outlet.

[0011] As an improvement of the present invention, the base body includes a top wall, a bottom wall and side walls, and the top wall, the bottom wall and the side walls jointly define a receiving space and a receiving opening; when the pet drinking water tray is in the closed state, the pet drinking water tray retracts into the receiving space through the receiving opening and automatically closes the water outlet; when the pet drinking water tray is in the open state, the pet drinking water tray extends out of the receiving space through the receiving opening and automatically opens the water outlet.

[0012] As an improvement of the present invention, the water sealing plug is provided with a connecting through hole, which is arranged at the center of the water sealing plug, and the movable pin and the water sealing plug are engaged and connected with the connecting protrusion through the connecting through hole.

[0013] As an improvement of the present invention, the pet water tray is further provided with a sliding assembly, which includes a sliding base and a sliding clamping piece. The top wall is provided with a sliding rail, and the sliding clamping piece is used to slide the sliding base and the sliding rail so that the pet water tray can be slidably connected to the base body.

[0014] As an improvement of the present invention, the top wall is further provided with a snap-fit ​​element, which is respectively arranged at the terminal positions of the sliding stroke of the slide rail to limit the sliding range of the pet drinking tray and provide positioning in the open and closed states.

[0015] As an improvement of the present invention, the bucket body is made of high-density polyethylene material through a hollow blow molding process.

[0016] As an improvement of the present invention, it also includes a filter assembly, which is used to filter the water flowing out of the bucket body; the filter assembly includes a filter element, a filter shell and a filter cover body, the filter shell is provided with a accommodating cavity and an accommodating opening connected to the accommodating cavity, the filter cover body covers the accommodating opening of the accommodating cavity, and the filter element is arranged in the accommodating cavity.

[0017] As an improvement of the present invention, the filter element is composed of filter cotton, an activated carbon bag and epoxy resin.

[0018] The beneficial effect of the present invention is that, through the above-mentioned structural arrangement, the sliding linkage mechanism between the pet drinking tray and the water outlet lid creates a closed-loop, self-responsive response between drinking behavior and water flow control: when the drinking tray is pushed to the open position, the water outlet lid automatically opens the outlet; when the drinking tray slides back to the closed position, the water outlet lid automatically closes the outlet. This design completely replaces the passive response mode of traditional float valves or gravity valves, achieving active control: "pushing the tray to release water, closing the tray to shut off the flow." Actual measurements show that the time from triggering the opening of the drinking tray to stable water flow is only 0.5 seconds, the latching response time is ≤0.2 seconds, and the seal failure rate is zero in 2000 cycle tests. Innovatively integrates sliding storage and water outlet control: When the water tray is closed, it retracts into the base, forming a fully enclosed cavity that isolates airborne contaminants such as dust and hair. Experiments have shown this reduces bacterial growth by 80%. Simultaneously, the water outlet is sealed, blocking the main body of the water tray from the outside air and slowing water quality degradation by three times. A single sliding action achieves both "water tray storage and water shutoff protection" during cleaning, eliminating the tedious manual valve closing required for traditional systems.

[0041] Reference Figures 1 to 12 , a pet water bottle for meeting the drinking needs of pets, comprising:

[0042] The water replenishment assembly 100 includes a water bucket body 110 and a water outlet bucket cover 120. The water bucket body 110 is provided with a water outlet bucket opening 111. The water outlet bucket cover 120 is used to open or close the water outlet bucket opening 111.

[0043] The base assembly 200 includes a base body 210 and a pet drinking water tray 220. The pet drinking water tray 220 is slidably connected to the base body 210, and the pet drinking water tray 220 has an open state and a closed state. The pet drinking water tray 220 can be switched between the closed state and the open state by sliding; when the pet drinking water tray 220 is in the closed state, the water outlet bucket cover 120 automatically closes the water outlet bucket opening 111; when the pet drinking water tray 220 is in the open state, the water outlet bucket cover 120 automatically opens the water outlet bucket opening 111.

[0044] The above-described structure enables autonomous control during use through a sliding state linkage mechanism. Conventional devices require manual operation of the valve to open and close the water outlet, which carries the risk of forgetfulness. This innovative mechanical coupling between the pet drinking tray 220 and the water outlet lid 120 allows the tray 220 to be slidably connected to the base body 210, forming a physical displacement input. This allows the sliding displacement of the pet drinking tray 220 to be directly converted into a water outlet control signal—triggering sealing when closed and water flow when open. Furthermore, the user's single push / pull operation of the pet drinking tray 220 is transformed into a dual-action output: "water flow opening and closing + storage protection," completely eliminating the need for manual valve opening and closing. This rigid binding of state switching and opening and closing actions addresses the vulnerability of traditional sealing mechanisms, such as float valves, to leakage due to sticking and aging. This invention establishes a mandatory state-action association rule: When the pet drinking tray 220 is closed, it seals the water outlet 111; when it is open, it clears the outlet 111. In this embodiment, the base assembly 200 and the water replenishment assembly 100 are fixed together by a snap-fit ​​connection. The base assembly 200 also includes a reinforcing pressure plate 240, a snap-fit ​​bracket 230, and a snap-fit ​​locking member 250. The snap-fit ​​bracket 230 is provided with a snap-fit ​​through-hole 231. The bucket body 110 is provided with a snap-fitting protrusion 160. The snap-fitting protrusion 160 snaps into engagement with the snap-fitting through-hole 231, thereby securing the base assembly 200 and the water replenishment assembly 100 together by a snap-fit ​​connection. The snap-fitting locking member 250 can optionally lock the snap-fitting through-hole 231. When the snap-fitting locking member 250 locks the snap-fitting through-hole 231, the snap-fitting protrusion 160 is fixed to the snap-fitting through-hole 231. When the snap-fitting locking member 250 unlocks the snap-fitting through-hole 231, the snap-fitting protrusion 160 can optionally be inserted into the snap-fitting through-hole 231. The reinforcing plate 240 is used to support the clamping bracket 230 , thereby making the clamping bracket 230 more stable. The clamping bracket 230 is fixedly connected to the base body 210 .

[0045] In this embodiment, the water outlet bucket cover 120 is provided with a water sealing plug 130, an axially movable movable pin 140 and a spring 150, the movable pin 140 includes an abutting protrusion 141, a connecting protrusion 142 and a connecting column 143, the abutting protrusion 141 and the connecting protrusion 142 are fixedly connected by the connecting column 143, and the abutting protrusion 141 is located below the connecting protrusion 142, the connecting protrusion 142 is connected to the water sealing plug 130, and the water sealing plug 130 is used to block or dredge the Water outlet bucket mouth 111; the water outlet bucket cover 120 is also provided with a mounting through hole 121 for the movable pin 140 to pass through and a bucket cover abutting portion 122 for abutting the spring 150; the spring 150 is sleeved on the connecting column 143, and its first end abuts the upper end of the abutting protrusion 141, and the second end abuts the bucket cover abutting portion 122. Under normal circumstances, the pet water drinking tray 220 is in the closed state, and the elastic force generated by the spring 150 drives the abutting protrusion 141 to move downward to block the water outlet bucket mouth 111. The above-mentioned structure allows a constant pressure seal to be established during use through the preload force of the spring 150. The spring 150 is sleeved on the connecting column 143, with its two ends rigidly abutting the abutting protrusion 141 and the barrel cover abutting portion 122. The movable pin 140 integrates the abutting protrusion 141, the connecting protrusion 142, and the connecting column 143 to form a force-conducting rigid body. Under normal conditions (when the pet drinking tray 220 is closed), the spring 150 presses down the abutting protrusion 141 with a constant preload force, which is then transmitted to the connecting protrusion 142 via the connecting column 143, driving the water sealing plug 130 to press against the sealing surface of the water outlet 111. This forms a mechanical constant pressure sealing system that is independent of the water level, completely eliminating the sealing force attenuation caused by the drop in liquid level in traditional float valves. The risk of transmission mechanism jamming is eliminated through axial linear motion constraint, as lever-type sealing mechanisms are prone to motion interference due to eccentric load wear. The present invention precisely defines the axial movement path of the movable pin 140 through the mounting hole 121. The diameter of the connecting post 143 is a clearance fit (≤0.1mm) with the mounting hole 121, allowing the movable pin 140 to move only in the vertical direction, eliminating lateral deflection. The spring 150 has no radial force component during compression and release, eliminating the torque loss associated with traditional rotary seals. After 20,000 cycles, the displacement deviation remains less than 0.05mm, with a zero sticking failure rate. A fail-safe seal is achieved through gravity-elastic dual redundancy. Failure of a single elastic element will result in seal collapse. The present invention creates a dual physical force redundancy system. By positioning the abutment protrusion 141 below the connecting protrusion 142, the center of gravity of the movable pin 140 is shifted downward, creating a backup sealing force. If the spring 150 breaks, the weight of the movable pin 140 and the water-sealing plug 130 still generates downward pressure to maintain the basic seal. When the spring 150 is intact, its elastic potential energy simultaneously generates the primary sealing force. Double protection greatly reduces the probability of sealing failure.

[0046] In this embodiment, a drinking tray abutment 221 is provided on the pet drinking tray 220; when the pet drinking tray 220 is in the closed state, the drinking tray abutment 221 is separated from the lower end of the abutment protrusion 141, and the force of the spring 150 drives the movable pin 140 to move downward, and then drives the water sealing plug 130 to move downward through the connecting protrusion 142 to automatically block the water outlet bucket mouth 111; when the pet drinking tray 220 is in the open state, the drinking tray abutment 221 pushes the abutment protrusion 141 to overcome the force of the spring 150 and move upward, and the movable pin 140 drives the connecting protrusion 142 to move upward through the connecting column 143, and then drives the water sealing plug 130 to move upward away from the water outlet bucket mouth 111 to realize automatic dredging of the water outlet bucket mouth 111. Through the arrangement of the above structure, when in use, the sliding displacement of the water drinking tray is accurately converted into the axial movement of the movable pin 140, which is the core mechanical linkage component for realizing automatic control of the water outlet 111 in the pet water bottle. Its function is to drive the water sealing plug 130, the movable pin 140, the spring 150 and other components to cooperate with each other through the opening and closing state of the pet water drinking tray 220 to achieve the automatic opening and closing of the water outlet 111: when the water drinking tray is in the closed state, the water drinking tray abutment portion 221 and the abutment portion 221 are in contact with each other. When the lower end of the connecting protrusion 141 separates, the spring force drives the movable pin 140 and the water sealing plug 130 downward, automatically sealing the water outlet 111 and achieving a reliable seal when not in use, preventing water leakage and water source contamination. When the drinking water tray abutment 221 switches to the open state, the drinking water tray abutment 221 pushes the abutment protrusion 141, forcing the movable pin 140 to overcome the spring force and move upward, simultaneously driving the water sealing plug 130 to disengage from the water outlet 111, completing the automatic unblocking of the water outlet 111 for water supply. The overall structure achieves "on-demand opening and closing" through purely mechanical transmission, without the need for electronic control. This not only ensures the convenience of pets drinking water, but also reduces manual operation through automatic sealing, improving the reliability and practicality of the pet water bottle.

[0047] In this embodiment, the base body 210 includes a top wall 211, a bottom wall 212, and side walls 213. These top, bottom, and side walls 213 collectively define a receiving space 214 and a receiving opening 215. When the pet drinking tray 220 is in the closed state, the pet drinking tray 220 retracts into the receiving space 214 through the receiving opening 215, automatically closing the water outlet 111. When the pet drinking tray 220 is in the open state, the pet drinking tray 220 extends out of the receiving space 214 through the receiving opening 215, automatically opening the water outlet 111. This structure enables "storage-extension" linkage control during use. The base body 210, enclosed by the top wall 211, bottom wall 212, and side walls 213, forms the receiving space 214 and the receiving opening 215, providing a stable storage and movement track for the pet drinking tray 220. When the pet drinking water tray 220 is in the closed state, the pet drinking water tray 220 retracts into the receiving space 214 through the receiving opening 215, synchronously triggering the automatic closure of the water outlet 111. This not only achieves compact storage of the drinking water tray and reduces the space occupied by the device, but also protects the water outlet from external contamination through the closed structure. When the pet drinking water tray 220 is in the open state, the pet drinking water tray 220 extends out of the receiving space 214 through the receiving opening 215, and the water outlet 111 is opened to supply water, ensuring that it is stably deployed for pet use. Overall, this structure, through spatial design and state linkage, achieves orderly storage and deployment of the pet drinking water tray 220 while synchronously controlling the opening and closing of the water outlet 111, taking into account the space utilization rate, ease of use, and drinking water hygiene of the device.

[0048] In this embodiment, the water sealing plug 130 is provided with a connecting through hole 131 , which is arranged at the center of the water sealing plug 130 , and the movable pin 140 and the water sealing plug 130 are engaged and connected with the connecting protrusion 142 through the connecting through hole 131 . Through the arrangement of the above structure, when in use, in the above structure, the water sealing plug 130 and the movable pin 140 are snap-connected through the connecting through hole 131 and the connecting protrusion 142 at the center position. Its core function is to construct a stable force transmission path to ensure the accuracy and synchronization of the linkage action of the two: the connecting through hole 131 is arranged at the center of the water sealing plug 130, which can ensure that the force of the connecting protrusion 142 on the water sealing plug 130 is evenly distributed on the central axis, avoiding the water sealing plug 130 from tilting due to force offset during the up and down movement, thereby ensuring that the water sealing plug 130 can be accurately aligned with the water outlet 111, improving the sealing performance during sealing (preventing offset leakage) and smoothness during opening (avoiding jamming). At the same time, the snap-fit ​​connection method enables the removable assembly of the movable pin 140 and the water sealing plug 130, facilitating subsequent maintenance and component replacement, and maintaining a stable linkage relationship during long-term use. This ensures that the spring force, the driving force of the water tray, etc., are efficiently transmitted to the water sealing plug 130 through the movable pin 140, ensuring the reliable implementation of the "blocking-unblocking" function. In summary, this structure, through central positioning and snap-fit ​​design, not only ensures the accuracy and sealing of mechanical transmission, but also takes into account the convenience of assembly and maintenance, which is an important guarantee for achieving the automatic opening and closing of the water outlet 111.

[0049] In this embodiment, the pet drinking tray 220 is further provided with a sliding assembly 222, which includes a sliding base 2221 and a sliding engaging member 2222. The top wall 211 is provided with a slide rail 2111. The sliding engaging member 2222 is used to slidably engage the sliding base 2221 with the slide rail 2111, thereby slidably connecting the pet drinking tray 220 to the base body 210. With this arrangement, during use, the sliding assembly 222 cooperates with the slide rail 2111 to achieve a slidable connection between the pet drinking tray 220 and the base body 210. The sliding engaging member 2222 forms a sliding auxiliary structure with the slide rail 2111 on the top wall 211, providing a stable sliding path for the pet drinking tray 220 along the slide rail 2111. This design enables the drinking water tray to switch smoothly between the closed state (retracted into the storage space) and the open state (extended into the storage space), ensuring that there is no jamming or offset during the linkage process. At the same time, the snapping action of the sliding clamp 2222 not only ensures the stability of the connection between the two (preventing the pet drinking water tray 220 from detaching from the base body 210), but also allows relative sliding (reducing friction resistance). In addition, the cooperation between the slide rail 2111 and the sliding assembly 222 can also accurately limit the sliding stroke of the pet drinking water tray 220, ensuring that it can accurately reach the predetermined position in both the open and closed states, forming a precise linkage with the opening and closing action of the water outlet 111. In summary, this structure, through the mechanical sliding design, not only ensures the flexible movement and reliable positioning of the pet drinking water tray 220, but also improves the operational convenience and stability of the entire device.

[0050] In this embodiment, the top wall 211 is further provided with a latching element 2112, which is disposed at the end positions of the sliding travel of the slide rail 2111, and is used to limit the sliding range of the pet water tray 220 and provide positioning in the open and closed states. With this configuration, when in use, the latching element 2112 acts as a mechanical limiter, disposed at the end positions of the sliding travel of the slide rail 2111 (i.e., the critical point between the open and closed states). When the pet water tray 220 slides to this position, the latching element 2112 physically blocks its further movement, ensuring that the pet water tray 220 is accurately positioned in both states.

[0051] In this embodiment, the bucket body 110 is made of high-density polyethylene (HDPE) through a blow molding process. This structural design, combined with the high-density polyethylene and blow molding process, ensures that the bucket body 110 combines structural strength, hygienic safety, and manufacturing flexibility. This not only meets the functional requirements of drinking water storage, but also extends product life and reduces user risks through its seamless design, impact resistance, and easy cleanability. This makes it an ideal container solution for pet water bottles. The bucket body 110 is translucent and features a water level scale on its exterior.

[0052] This embodiment also includes a filter assembly 300 for filtering water flowing out of the bucket body 110. The filter assembly 300 comprises a filter cartridge 310, a filter housing 320, and a filter cover 330. The filter housing 320 defines a receiving chamber 321 and an opening 322 communicating with the receiving chamber 321. The filter cover 330 covers the opening 322 of the receiving chamber 321, and the filter cartridge 310 is disposed within the receiving chamber 321. With this configuration, when in use, the filter assembly 300, through the combination of the filter cartridge 310, the filter housing 320, and the filter cover 330, purifies water flowing out of the bucket body 110. This structural coordination achieves effective water purification, balances reliable filtration with easy maintenance, and provides a safe and clean drinking water source for pets. A sealing ring 170 is provided between the filter assembly 300 and the water outlet cover 120 to enhance sealing.

[0053] In this embodiment, the filter element 310 is composed of filter cotton, an activated carbon bag, and epoxy resin. With this structure, when in use, the filter element 310 utilizes a combination of filter cotton, activated carbon bag, and epoxy resin. Its primary function is to achieve a step-by-step water purification process through the synergistic cooperation of these three layers, while also ensuring structural stability. The filter cotton acts as a pre-filtration layer, intercepting larger particles (such as silt and suspended solids) in the water through its porous structure, providing pretreatment and reducing the load on the subsequent activated carbon. The activated carbon bag utilizes its abundant pores to absorb odors, organic pollutants, and fine impurities in the water, achieving deep purification and improving the taste and safety of the drinking water. The epoxy resin acts as an encapsulating material, tightly integrating the filter cotton and activated carbon bag into a single unit, preventing loosening or displacement of the materials. It also seals gaps to prevent bypass leakage of unfiltered water, ensuring that all water flows through the filtration path. The combination of these three layers not only achieves water purification from coarse to fine quality through layered filtration, but also, thanks to the epoxy resin encapsulation, ensures the integrity and durability of the filter element structure, providing clean and safe drinking water for pets and further enhancing the user experience.
