A pet water bottle

Abstract

This utility model discloses a pet water bottle with a sliding linkage switch mechanism to solve the problems of leakage, contamination, and cumbersome operation caused by the inability of traditional watering devices to automatically open and close the water outlet. The pet water bottle includes a water replenishment component and a base component: the water tank body of the water replenishment component has a water outlet, which is controlled by a water outlet cap; the pet drinking tray of the base component is slidably connected to the base body and has two states: open and closed. Through the above structure, during use, the sliding state of the drinking tray is automatically linked to the opening and closing of the water outlet—when the drinking tray slides to the closed state, it drives the water outlet cap to automatically close the water outlet; when it slides to the open state, it drives the water outlet cap to automatically open the water outlet. Its beneficial effects are: precise control of "pushing the tray to dispense water and closing the tray to stop the flow" is achieved through mechanical linkage, with a response time ≤0.5 seconds; the spring pre-tightening sealing mechanism ensures zero leakage under 10kPa water pressure.

Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, specifically to a pet drinking device with a sliding linkage switch mechanism that can automatically open and close the water outlet. Background Technology

[0002] With the increasing penetration rate of pet households, traditional mechanical pet water dispensers are widely used due to their simple structure and low cost. However, these devices have fundamental defects in the field of automatic water outlet control, mainly in the following three aspects: First, they rely heavily on manual operation and cannot achieve simultaneous automatic opening and closing of the water filling channel when switching between unfolded and folded storage states. Mainstream gravity-fed water bottles rely on cumbersome operation and lack a sliding linkage switch mechanism, resulting in multiple and complex manual operation steps. Existing gravity-fed water bottles with folding water trays have independent opening and closing of the water filling switch, making it impossible to achieve linkage between the unfolded state and the water filling mode. Second, the mechanical seal has insufficient reliability and there is a risk of leakage. Although existing float valve-controlled devices can achieve liquid level sensing, their sealing structure has inherent defects: the float linkage mechanism is prone to scale buildup and jamming after long-term immersion, causing the float to fail to fully reset; the sealing rubber ring is permanently deformed after frequent compression, losing its elastic sealing ability. Experiments show that the leakage rate of traditional float valves is as high as 23% after 2000 opening and closing cycles. Third, rigid structures lead to a conflict between hygiene and space. Fixed water trays are constantly exposed to the air, allowing pet hair, dust, and other contaminants to fall directly into the water, resulting in bacterial growth more than four times faster than in enclosed structures. While removable and washable water trays can improve hygiene, each cleaning requires manually closing the water outlet (e.g., tightening the lid or disconnecting the hose), which is cumbersome and relies on manual intervention. Some products attempt to use foldable water trays to save space, but even when folded, the water outlet cannot be automatically closed, leaving the water tank continuously exposed to the air and accelerating water quality deterioration.

[0003] In summary, developing a mechanical drinking device that can achieve self-locking linkage of the water outlet and also has hygienic protection functions has become a technological bottleneck that urgently needs to be overcome in the pet supplies industry. Therefore, this utility model provides a pet water bottle based on sliding mechanical linkage, which completely solves the above problems through an innovative spring-abutment block transmission mechanism. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model 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 problems 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 this utility model to solve its technical problem is:

[0006] A pet water bottle for meeting the drinking needs of pets, comprising:

[0007] A water replenishment component includes a water tank body and a water outlet cover. The water tank body is provided with a water outlet, and the water outlet cover is used to open or close the water outlet.

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

[0009] As an improvement of this utility model, the water outlet lid 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 post. The abutting protrusion and the connecting protrusion are fixedly connected by the connecting post, 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 block or unclog the water outlet. The water outlet lid is also provided with an installation through hole for the movable pin to pass through and a lid abutting part for abutting the spring. The spring is sleeved on the connecting post, with its first end abutting the abutting protrusion and its second end abutting the lid abutting part. Under normal conditions, the pet drinking dish is in the closed state, and the elastic force generated by the spring drives the abutting protrusion to move downward to block the water outlet.

[0010] As an improvement of this utility model, the pet water bowl is provided with a water bowl abutment; when the pet water bowl is in the closed state, the water bowl abutment separates from the abutment protrusion, the spring force drives the movable pin to move downward, and then drives the water sealing plug to move downward through the connecting protrusion to automatically seal the water outlet; when the pet water bowl is in the open state, the water bowl abutment pushes the abutment protrusion to move upward against the spring force, the movable pin drives the connecting protrusion to move upward through the connecting post, and then drives the water sealing plug to move upward away from the water outlet to achieve automatic unblocking of the water outlet.

[0011] As an improvement of this utility model, the base body includes a top wall, a bottom wall, and a side wall, the top wall, the bottom wall, and the side wall together define a receiving space and a receiving opening; when the pet water dish is in the closed state, the pet water dish retracts into the receiving space through the receiving opening and automatically closes the water outlet; when the pet water dish is in the open state, the pet water dish extends out of the receiving space through the receiving opening and automatically opens the water outlet.

[0012] As an improvement of this utility model, the water sealing plug is provided with a connecting through hole, which is located at the center of the water sealing plug, and the movable pin and the water sealing plug are engaged with the connecting protrusion through the connecting through hole.

[0013] As an improvement of this utility model, the pet water bowl is further provided with a sliding component, which includes a sliding base and a sliding connector. The top wall is provided with a slide rail, and the sliding connector is used to slide and engage the sliding base with the slide rail, so that the pet water bowl can be slidably connected to the base body.

[0014] As an improvement of this utility model, the top wall is also provided with a snap-fit ​​element, which is respectively set at the end position of the sliding stroke of the slide rail, for limiting the sliding range of the pet water bowl and providing positioning in the open and closed states.

[0015] As an improvement to this utility model, the main body of the water bucket is made of high-density polyethylene through a hollow blow molding process.

[0016] As an improvement to this utility model, a filter assembly is also included, which is used to filter the water flowing out of the main body of the water bucket; the filter assembly includes a filter element, a filter housing and a filter cover, the filter housing is provided with a receiving cavity and a receiving opening communicating with the receiving cavity, the filter cover covers the receiving opening of the receiving cavity, and the filter element is disposed in the receiving cavity.

[0017] As an improvement to this utility model, the filter element is composed of filter cotton, activated carbon pack and epoxy resin.

[0018] The beneficial effects of this utility model are as follows: Through the above-described structure, during use, the pet drinking dish and the water outlet lid form a closed-loop self-response mechanism through a sliding linkage mechanism: when the drinking dish is pushed to the open state, the water outlet lid automatically opens the water outlet; when the drinking dish slides back to the closed state, the water outlet lid automatically closes the water outlet. This design completely replaces the passive response mode of traditional float valves or gravity valves, achieving active control of "pushing the dish to dispense water and closing the dish to stop the flow." Actual tests show that it only takes 0.5 seconds from the time the drinking dish is triggered to the time the water flow is stable, the locking response time is ≤0.2 seconds, and the sealing failure rate is zero in 2000 cycle tests. This innovative device integrates sliding storage and water outlet control: when the drinking tray is closed, it retracts into the base to form a fully enclosed cavity, isolating it from airborne contaminants such as dust and hair, resulting in an 80% reduction in bacterial growth. Simultaneously, it seals the water outlet, preventing the water tank from connecting to the outside air, slowing water quality deterioration by three times. Cleaning requires only a single sliding operation to simultaneously complete both the water tray storage and water shut-off protection, eliminating the cumbersome step of manually closing the valve before disassembling and cleaning traditional devices.

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

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

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

[0044] With the above-described structure, autonomous control is achieved through a sliding linkage mechanism during use: traditional devices require manual operation of the valve to open and close the water outlet, posing a risk of forgetting the operation. This invention innovatively sets up a mechanical coupling between the pet water tray 220 and the water outlet cover 120, allowing the pet water tray 220 to slide on the base body 210, forming a physical displacement input end. This allows the sliding displacement of the pet water tray 220 to be directly converted into a water outlet control signal—triggering a sealing action when closed and a water flow action when open. Furthermore, it transforms the single operation of pushing / pulling the pet water tray 220 into a dual output of "water flow opening / closing + storage and protection," completely eliminating the need for manual valve operation. By rigidly binding state switching with opening / closing actions, it solves the problem of leakage caused by jamming or aging in traditional sealing mechanisms such as float valves. This invention establishes a mandatory state-action association rule: the pet water tray 220 forcibly seals the water outlet 111 when closed and forcibly unblocks the water outlet 111 when open. 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 further 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, and the water tank body 110 is provided with a snap-fit ​​protrusion 160. The snap-fit ​​protrusion 160 engages with the snap-fit ​​through hole 231 to fix the base assembly 200 and the water replenishment assembly 100 together by a snap-fit ​​connection. The snap-fit ​​locking member 250 can optionally lock the snap-fit ​​through hole 231. When the snap-fit ​​locking member 250 locks the snap-fit ​​through hole 231, the snap-fit ​​protrusion 160 is fixed in the snap-fit ​​through hole 231. When the snap-fit ​​locking member 250 unlocks the snap-fit ​​through hole 231, the snap-fit ​​protrusion 160 can optionally be inserted into the snap-fit ​​through hole 231. The reinforcing pressure plate 240 is used to hold the snap-fit ​​bracket 230 in place, thereby making the snap-fit ​​bracket 230 more stable. The snap-fit ​​bracket 230 is fixedly connected to the base body 210.

[0045] In this embodiment, the water outlet cover 120 is provided with a water-sealing plug 130, an axially movable pin 140, and a spring 150. The movable pin 140 includes an abutting protrusion 141, a connecting protrusion 142, and a connecting post 143. The abutting protrusion 141 and the connecting protrusion 142 are fixedly connected by the connecting post 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 unclog the water outlet. The water outlet 111; the water outlet cover 120 is also provided with a mounting through hole 121 for the movable pin 140 to pass through and a cover abutting part 122 for abutting the spring 150; the spring 150 is sleeved on the connecting post 143, with its first end abutting the upper end of the abutting protrusion 141 and its second end abutting the cover abutting part 122. Under normal conditions, the pet 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 111. With the above-described structure, during use, a constant pressure seal is established by the preload of spring 150. Spring 150 is sleeved on the connecting post 143, and its two ends rigidly abut against the abutment protrusion 141 and the abutment part 122 of the bucket lid. The movable pin 140 integrates the abutment protrusion 141, the connecting protrusion 142, and the connecting post 143 to form a rigid force transmission body. Under normal conditions (when the pet drinking tray 220 is closed), spring 150 presses down on the abutment protrusion 141 with a constant preload → the force is transmitted through the connecting post 143 to the connecting protrusion 142 → driving the sealing plug 130 to press against the sealing surface of the water outlet 111. This forms a mechanical constant pressure sealing system independent of water level, completely eliminating the sealing force attenuation caused by the drop in liquid level in traditional float valves. The risk of jamming in the transmission mechanism is eliminated by axial linear motion constraint, as lever-type sealing mechanisms are prone to motion interference due to wear caused by off-center load. This invention precisely defines the axial movement path of the movable pin 140 through the mounting through hole 121; the diameter of the connecting post 143 is fitted with the mounting through hole 121 with a clearance fit (≤0.1mm), ensuring that the movable pin 140 can only move linearly in the vertical direction, eliminating lateral displacement; the spring 150 has no radial force during compression / release, avoiding torque loss in traditional rotary sealing mechanisms; after 20,000 cycles, the displacement deviation is still <0.05mm, and the jamming failure rate is zero. A fail-safe seal is achieved through gravity-elastic force dual redundancy backup, as failure of a single elastic element will lead to seal collapse. This invention creates a dual physical force redundancy system by positioning the abutment protrusion 141 below the connecting protrusion 142, causing the overall center of gravity of the movable pin 140 to be lowered, forming a backup sealing force: when the spring 150 breaks, the weight of the movable pin 140 and the sealing plug 130 can still generate downward pressure to maintain the basic seal; when the spring 150 is intact, the elastic potential energy of the spring 150 simultaneously forms the main sealing force. The dual protection significantly reduces the probability of seal failure.

[0046] In this embodiment, the pet water bowl 220 is provided with a water bowl abutment 221. When the pet water bowl 220 is in the closed state, the water bowl abutment 221 separates from the lower end of the abutment protrusion 141. The spring 150 forces the movable pin 140 to move downward, thereby driving the water sealing plug 130 to move downward through the connecting protrusion 142 to automatically seal the water outlet 111. When the pet water bowl 220 is in the open state, the water bowl abutment 221 pushes the abutment protrusion 141 to move upward against the force of the spring 150. The movable pin 140 drives the connecting protrusion 142 to move upward through the connecting post 143, thereby driving the water sealing plug 130 to move upward away from the water outlet 111 to achieve automatic unblocking of the water outlet 111. With the above-described structure, during use, the sliding displacement of the water tray is precisely converted into the axial movement of the movable pin 140. This is the core mechanical linkage component in the pet water bottle that enables automatic control of the water outlet 111. Its function is to drive the water seal 130, the movable pin 140, the spring 150, and other components to work together through the opening and closing states of the pet water tray 220, thereby achieving the automatic opening and closing of the water outlet 111. When the water tray is in the closed state, the water tray abutment part 221 and the abutment... When the lower end of the protrusion 141 separates, the spring force drives the movable pin 140 and the water-sealing plug 130 to move downwards, automatically sealing the water outlet 111, achieving a reliable seal in the non-use state and preventing water leakage and water source contamination. When the drinking tray abutment part 221 switches to the open state, the drinking tray abutment part 221 pushes the abutment protrusion 141, forcing the movable pin 140 to overcome the spring force and move upwards, 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 pure mechanical transmission, without the need for electronic control, ensuring the convenience of pet drinking water, and reducing manual operation through automatic sealing, thus 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 a side wall 213. The top wall 211, the bottom wall 212, and the side wall 213 together define a receiving space 214 and a receiving opening 215. When the pet water dish 220 is in the closed state, the pet water dish 220 retracts into the receiving space 214 through the receiving opening 215 and automatically closes the water outlet 111. When the pet water dish 220 is in the open state, the pet water dish 220 extends out of the receiving space 214 through the receiving opening 215 and automatically opens the water outlet 111. Through the above structural design, "retraction-extension" linkage control can be achieved during use. The base body 210, through the top wall 211, the bottom wall 212, and the side wall 213, encloses the receiving space 214 and the receiving opening 215, providing a stable storage and movement track for the pet water dish 220. When the pet water bowl 220 is closed, it retracts into the receiving space 214 through the receiving opening 215, simultaneously triggering the automatic closing of the water outlet 111. This achieves compact storage of the water bowl, reducing the space occupied by the device, and protects the water outlet from external contamination through the closed structure. When the pet water bowl 220 is open, it extends out of the receiving space 214 through the receiving opening 215, simultaneously opening the water outlet 111 to supply water, ensuring stable deployment for pet use. Overall, this structure, through spatial design and state linkage, achieves orderly storage and deployment of the pet water bowl 220 while simultaneously controlling the opening and closing of the water outlet 111, balancing space utilization, ease of use, and water hygiene.

[0048] In this embodiment, the water-sealing plug 130 is provided with a connecting through hole 131, which is located at the center of the water-sealing plug 130. The movable pin 140 and the water-sealing plug 130 are engaged with the connecting protrusion 142 through the connecting through hole 131. With the above structure, in use, the sealing plug 130 and the movable pin 140 are engaged and connected through the connecting through hole 131 and the connecting protrusion 142 at the center position. Its core function is to build a stable force transmission path to ensure the accuracy and synchronization of their linkage action. The connecting through hole 131 is located at the center of the sealing plug 130, which can ensure that the force exerted by the connecting protrusion 142 on the sealing plug 130 is evenly distributed on the central axis, preventing the sealing plug 130 from tilting due to force deviation during up and down movement. This ensures that the sealing plug 130 can be accurately aligned with the water outlet 111, improving the sealing performance during sealing (preventing displacement and leakage) and the smoothness during opening (preventing jamming). Meanwhile, the snap-fit ​​connection allows for the detachable assembly of the movable pin 140 and the sealing plug 130, facilitating future maintenance and component replacement. It also ensures a stable linkage during long-term use, guaranteeing that spring force and drinking tray driving force are efficiently transmitted to the sealing plug 130 via the movable pin 140, thus ensuring the reliable implementation of the "blocking-unblocking" function. In summary, this structure, through its central positioning and snap-fit ​​design, ensures both the precision and sealing of mechanical transmission while also balancing ease of assembly and maintenance, making it a crucial guarantee for the automatic opening and closing of the water outlet 111.

[0049] In this embodiment, the pet water bowl 220 is further provided with a sliding assembly 222. The sliding assembly 222 includes a sliding base 2221 and a sliding connector 2222. The top wall 211 is provided with a slide rail 2111. The sliding connector 2222 is used to slide and engage the sliding base 2221 with the slide rail 2111, so that the pet water bowl 220 is slidably connected to the base body 210. With the above structure, in use, the sliding assembly 222 and the slide rail 2111 cooperate to achieve a slidable connection between the pet water bowl 220 and the base body 210. The sliding connector 2222 and the slide rail 2111 of the top wall 211 form a sliding pair structure, providing a stable sliding track for the pet water bowl 220 along the direction of the slide rail 2111. This design allows the water dish to smoothly switch between a closed state (retracted into the storage space) and an open state (extended into the storage space), ensuring no jamming or misalignment during operation. Simultaneously, the locking action of the sliding connector 2222 ensures both the stability of the connection (preventing the pet water dish 220 from detaching from the base body 210) and allows for relative sliding (reducing frictional resistance). Furthermore, the cooperation between the slide rail 2111 and the sliding component 222 precisely limits the sliding stroke of the pet water dish 220, ensuring it accurately reaches the predetermined position in both open and closed states, forming a precise linkage with the opening and closing action of the water outlet 111. In summary, this structure, through its mechanical sliding design, ensures both the flexible movement and reliable positioning of the pet water dish 220, while also improving the overall ease of operation and stability of the device.

[0050] In this embodiment, the top wall 211 is further provided with a locking element 2112. The locking element 2112 is respectively disposed at the end position of the sliding stroke of the slide rail 2111, and is used to limit the sliding range of the pet water bowl 220 and provide positioning in the open and closed states. With the above structure, in use, the locking element 2112 acts as a mechanical limiting structure, and is respectively disposed at the end of the sliding stroke of the slide rail 2111 (i.e., the critical point between the open and closed states). When the pet water bowl 220 slides to this position, the locking element 2112 physically blocks its continued movement, ensuring that the pet water bowl 220 can accurately stop in both states.

[0051] In this embodiment, the water bucket body 110 is made of high-density polyethylene using a hollow blow molding process.

The water bucket body 110 is generally semi-transparent and has water level markings on its outer surface.

[0052] In this embodiment, a filter assembly 300 is also included. The filter assembly 300 is used to filter the water flowing out of the water tank body 110. The filter assembly 300 includes a filter element 310, a filter housing 320, and a filter cover 330. The filter housing 320 has a receiving cavity 321 and a receiving opening 322 communicating with the receiving cavity 321. The filter cover 330 covers the receiving opening 322 of the receiving cavity 321, and the filter element 310 is disposed within the receiving cavity 321. With the above-described structure, in use, the filter assembly 300, through the combined design of the filter element 310, the filter housing 320, and the filter cover 330, achieves purification of the water flowing out of the water tank body 110. The structural cooperation achieves effective water purification, balancing the reliability of the filtration function with the convenience of maintenance, providing 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 the sealing performance.

[0053] In this embodiment, the filter element 310 is composed of filter cotton, activated carbon pack, and epoxy resin. With the above structural design, in use, the filter element 310, composed of filter cotton, activated carbon pack, and epoxy resin, primarily achieves step-by-step purification of water quality through the synergistic cooperation of these three materials, while ensuring structural stability: the filter cotton, as a pre-filtration layer, intercepts larger particulate impurities (such as silt and suspended solids) in the water with its porous structure, playing a pre-treatment role and reducing the load on the subsequent activated carbon; the activated carbon pack utilizes its abundant pores to adsorb odors, organic pollutants, and tiny impurities in the water, achieving deep purification and improving the taste and safety of drinking water; the epoxy resin, as an encapsulation material, tightly binds the filter cotton and activated carbon pack into a whole, preventing materials from loosening or shifting, while sealing gaps to prevent unfiltered water from bypassing and leaking, ensuring that all water flows through the filtration path. The combination of these three components achieves water purification from coarse to fine through layered filtration, and 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.
