Description

Technical Field

[0001] The invention relates to a pet drinking fountain. Background Art

[0002] Existing drinking fountains without water pumps consist of three parts: a water storage device, a water cover with a one-way valve, and a drinking water container. When the water storage device, filled with water, is placed above the drinking water container, the one-way valve on the water cover is pushed open, allowing water in the water storage device to flow into the drinking water container, and air to enter the water storage device through the open one-way valve. When the water level in the drinking water container reaches the opening on the water cover, the opening of the one-way valve is blocked by water, blocking air intake and, in turn, water outflow, achieving equilibrium. When some water in the drinking water container is consumed, the water level drops below the opening on the water cover, allowing air to enter the water storage device, causing water in the water storage device to flow into the drinking water container until equilibrium is reached again.

[0003] The water storage device of existing drinking fountains without water pumps is inverted above the drinking container via a water cap with a one-way valve. This allows the water in the drinking container and the water in the water storage device to communicate. When pets drink water, they deposit saliva bacteria and parasites into the water bowl, further contaminating the water in both the drinking container and the water storage device. Furthermore, the air inlet and water outlet of existing drinking fountains without water pumps share a single opening, requiring both the outlet and air inlet to be located within the drinking container.

[0004] There is also a type of pet drinking fountain on the market with a water pump. The water storage device is integrated with the drinking container. When the pet drinks water, it will leave saliva bacteria and parasites in the drinking container, thereby contaminating the drinking water in the entire container and breeding bacteria and viruses. Summary of the Invention

[0005] In order to overcome the above shortcomings, the purpose of the present invention is to provide a pet drinking fountain that can completely separate the water in the water storage device from the water in the drinking water container, so that the water in the water storage device is not contaminated, is more hygienic, and has a longer storage period for clean water.

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a pet drinking fountain, comprising a water storage device and a drinking water container, the water storage device comprising a water storage barrel, an air inlet assembly, and a water outlet assembly, the air inlet assembly and the water outlet assembly are respectively arranged on the air inlet and water outlet of the water storage barrel, and the two are separated; the air inlet assembly has an air inlet channel, one end of the air inlet channel is connected to the water storage barrel, and the other end leads to the drinking water container; the lower end surface of the water outlet assembly is higher than the lower end surface of the air inlet assembly, the water outlet assembly comprises a water outlet cover, the water outlet cover is installed on the water outlet, and the water outlet cover has a water outlet channel, one end of the water outlet channel is connected to the water storage barrel, and the other end leads to the drinking water container.

[0007] The beneficial effect of the pet drinking fountain of the present invention is that, because the air inlet and water outlet components are separated, and the lower end surface of the water outlet component is higher than the lower end surface of the air inlet component, the storage and drinking functions of the pet's drinking water are separated. The structure is simple, practical, stable, and easy to clean. This improves the water storage function of the pet drinking fountain, preventing the stored water from being contaminated, and allowing for the storage of more clean water for a long period of time. This solves the technical problem of existing pet drinking fountains on the market that cannot separate the stored clean water from the water consumed by the pet, and cannot automatically refill water without external force.

[0008] Preferably, the water storage device can be integrally formed on the drinking water container, or can be detachably provided on the drinking water container.

[0009] Preferably, when the water storage device and the drinking water container are detachable, a sealing one-way valve is provided in the air inlet channel, a push rod of the air inlet valve is provided on the drinking water container, a water outlet one-way valve is provided on the water outlet cover to seal the water outlet channel, and a push rod of the water outlet one-way valve is provided on the drinking water container; when the water storage device is mounted on the drinking water container, the air inlet one-way valve and the water outlet one-way valve are respectively pushed open by the push rod of the air inlet one-way valve and the push rod of the water outlet one-way valve. When the water storage device is mounted on the drinking water container, the air inlet one-way valve and the water outlet one-way valve are respectively opened; when the water storage device is removed from the drinking water container, the air inlet one-way valve and the water outlet one-way valve are respectively closed.

[0010] Preferably, the air intake assembly includes an air intake pipe and a water level control pipe connected from top to bottom to form an air intake passage. The top end of the air intake pipe leads to the top of the water storage barrel. The water level control pipe is located within the drinking water container. An air intake inlet is provided at the lower end of the water level control pipe. The air intake passage check valve is installed above the water level control pipe to seal the air intake passage. The air intake pipe is connected to the water storage barrel, and the water level control pipe is connected to the drinking water container. The air intake inlet on the water level control pipe allows external air to enter the air intake pipe and then enter the water storage barrel from the air intake pipe, thereby balancing the air pressure inside the water storage barrel with that outside, and the water in the water storage barrel is discharged from the water outlet by gravity.

[0011] Preferably, the air intake pipe can be arranged inside the water storage barrel or outside the water storage barrel, as long as it can be communicated with the water storage barrel and can supply air into the water storage barrel.

[0012] Preferably, the water outlet assembly further includes a guide groove disposed on the drinking water container. The water outlet one-way valve push rod is disposed within the guide groove and corresponds to the water outlet one-way valve. The guide groove extends toward the drinking water dish of the drinking water container and is located above the drinking water dish. The guide groove can guide liquid from the water outlet into the drinking water container or the drinking water dish of the drinking water container.

The circulating filter device includes a water pump and a filter assembly. The water inlet of the water pump is connected to the filter assembly via a pipe, and the water outlet of the water pump leads to the bottom of a drinking water dish. The bottom of the drinking water dish is lower than the air inlet of the air inlet passage, and the dish opening of the drinking water dish is higher than the air inlet of the air inlet passage. The bottom of the drinking water dish is provided with a through hole that communicates with the filter assembly. The filter assembly filters the liquid in the drinking water dish and the drinking water container. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the scope of protection of the present invention. Figure 1-3As shown, a pet drinking fountain of this embodiment includes a water storage device 100 and a drinking water container 200. The water storage device 100 includes a water storage barrel 110, an air inlet assembly 120, and a water outlet assembly 130. The air inlet assembly 120 and the water outlet assembly 130 are respectively arranged on the air inlet and the water outlet of the water storage barrel 110, and the two are separated; the air inlet assembly 120 has an air inlet channel, one end of the air inlet channel is connected to the water storage barrel 110, and the other end leads to the drinking water container 200; the lower end surface of the water outlet assembly 130 is higher than the lower end surface of the air inlet assembly 120, and the water outlet assembly includes a water outlet cover 132, which is installed on the water outlet, and the water outlet cover 132 has a water outlet channel, one end of the water outlet channel is connected to the water storage barrel 110, and the other end leads to the drinking water container 200.

[0023] The water storage device 100 may be integrally formed on the drinking water container 200 or detachably provided on the drinking water container 200 .

[0024] When a detachable manner is adopted, an air inlet channel one-way valve 121 for sealing is provided in the air inlet channel, an air inlet channel one-way valve push rod 210 is provided on the drinking water container 200, a water outlet one-way valve 131 for sealing the water outlet channel is provided on the water outlet cover 132, and a water outlet one-way valve push rod 220 is provided on the drinking water container 200; when the water storage device 100 is installed on the drinking water container 200, the air inlet channel one-way valve 121 and the water outlet one-way valve 131 are pushed open by the air inlet channel one-way valve push rod 210 and the water outlet one-way valve push rod 220 respectively.

[0025] like Figure 3-6 As shown, the air intake assembly 120 in this embodiment includes at least the following components: an air intake pipe 122, which connects from top to bottom to form an air intake passage, a water level control pipe 123, and the aforementioned air intake passage check valve 121. The top end of the air intake pipe 122 leads to the top of the water storage barrel 110. The water level control pipe 123 is located within the drinking water container 200. The lower end of the water level control pipe 123 is provided with an air intake inlet. The air intake passage check valve 121 is installed above the water level control pipe 123 to seal the air intake passage. Specifically, when the water storage device 100 is separated from the drinking water container 200, the air intake passage check valve 121 seals the air intake passage. When the water storage device 100 is installed in the drinking water container 200, the air intake passage check valve 121 opens the front air intake passage.

[0026] The structure of the air intake assembly 120 in this embodiment can be modified in various ways, and the installation position of the air intake duct 122 can also be modified according to different needs. The air intake duct 122 can be installed inside the water storage tank 110 or outside the water storage tank 110, as long as it can communicate with the water storage tank and supply air into the water storage tank 110.

[0027] The air intake assembly 120 in this embodiment provides the following three structures:

[0028] like Figure 3 、 4 As shown, the first structure of the air intake assembly 120 is as follows: the air intake pipe 122 is disposed inside the water storage barrel 110. The air intake pipe 122 is integrally formed within the water storage barrel 110. The water level control pipe 123 is detachably connected to the lower end of the water storage barrel 110, and the detachable connection is sealed. To facilitate the detachable connection of the water level control pipe 123 to the lower end of the water storage barrel 110, an air intake connecting pipe 110a is integrally formed at the bottom of the water storage barrel 110. The upper end of the water level control pipe 123 is detachably connected to the air intake connecting pipe 110a. There are various detachable connection methods, such as threaded connection, snap-fit connection, and bolt connection.

[0029] The intake passage one-way valve 121 opens / closes the intake passage by means of an elastic component or its own structure.

[0030] The following takes the elastic component as the intake spring 124 as an example to describe the structure in detail: Figure 4 As shown, the water level control tube 123 has a horizontal baffle 123a, through which the air intake check valve 121 passes. An air intake spring 124 is mounted below the check valve 121, forcing the upper end of the check valve 121 to permanently seal against the baffle 123a. The upper end of the check valve 121 is made of silicone. When the water storage device 100 is not mounted on the drinking water container 200, the elasticity of the air intake spring 124 constantly controls the silicone seal against the check valve 121. In this case, the air intake is blocked, preventing air from venting from the intake duct 122 of the air intake assembly into the water storage tank 110. After the water storage device 100 is installed on the drinking water container 200, the air intake channel one-way valve 121 is lifted by the air intake channel one-way valve push rod 210, the air intake spring 124 is compressed, and the air intake channel one-way valve 121 is separated from the horizontal partition 123a, creating a gap. At this time, the air intake channel is opened, and air is discharged from the air intake pipe 122 of the air intake assembly into the water storage barrel 110.

[0031] The above is the working principle of the intake channel one-way valve 121 using elastic components to close and open the intake channel. Of course, there are also some ways to close and open the intake channel through the structure of the intake channel one-way valve 121 itself.

[0032] like Figure 5As shown, the second configuration of the air intake assembly 120 is as follows: the air intake pipe 122 remains located within the water storage barrel 110. The air intake pipe 122 is connected to the water level control pipe 123 via an air intake cover 125. The air intake cover 125 is detachably mounted on the air intake of the water storage barrel 110. To facilitate installation of the air intake cover 125, an air intake connecting pipe 110a is provided at the bottom of the water storage barrel 110, and the air intake cover 125 is detachably connected to the air intake connecting pipe 110a. The provision of the air intake cover 125 allows the air intake cover 125 to be removed, thereby allowing the entire air intake assembly to be disassembled and cleaned. Similarly, various detachable connection methods exist, such as threaded connections, snap-fit connections, and bolted connections. The air intake channel check valve 121 is mounted on the air intake cover 125. If an air intake spring 124 is used, the air intake spring 124 is mounted on the air intake channel one-way valve 121 located below the air intake cover 125. The upper end of the air intake channel one-way valve 121 is also made of silicone. The air intake cover 125 is sealed by the cooperation of the silicone on the upper end of the air intake channel one-way valve 121 and the air intake spring 124.

[0033] When the water storage device 100 is not installed on the drinking water container 200, the silicone sealant on the upper end of the inlet channel check valve 121 and the air inlet spring 124 cooperate to seal the air inlet cover 125, blocking the air inlet channel and preventing the flow of water and air within. After the water storage device 100 is installed on the drinking water container 200, the inlet channel check valve 121 is lifted by the inlet channel check valve push rod 210, compressing the air inlet spring 124. The silicone sealant on the upper end of the inlet channel check valve 121 separates from the air inlet cover 125, creating a gap. This opens the air inlet channel, allowing the flow of water and air within.

[0034] The water level control tube 123 can be integrally formed on the air inlet cover 125 or the drinking water container 200, eliminating the need for additional installation and facilitating assembly. Alternatively, the water level control tube 123 can be detachably mounted on the air inlet cover 125 or the drinking water container 200, facilitating cleaning of the water level control tube 123 and replacement of other water level control tubes at different heights, thereby improving its applicability.

[0035] like Figure 6As shown, the third structure of the air intake assembly 120 is: the air intake pipe 122 is arranged outside the water storage barrel 110 and is connected to the top of the water storage barrel 110. The air intake pipe 122 and the water storage barrel 110 are detachably connected or integrally formed. The lower end of the air intake pipe 122 is detachably connected to the upper end of the water level control pipe 123 and the detachable connection is sealed. Similarly, there are many detachable connection methods, such as threaded connection, snap connection and bolt connection. The air intake channel one-way valve 121 is passed through the air intake pipe 122, and the air intake spring 124 is sleeved on the air intake channel one-way valve 121 below the air intake pipe 122. The upper end of the air intake channel one-way valve 121 can also be made of silicone. The air intake spring 124 cooperates with the silicone to seal and open the air intake pipe 122, and then seal and open the air intake channel.

[0036] When air is introduced into the water storage tank 110, the liquid within is discharged from the water outlet assembly 130. Similarly, when the water storage device 100 is detached from the drinking water container 200, the outlet check valve 131 closes the water outlet passage; when the water storage device is attached to the drinking water container, the outlet check valve 131 opens the water outlet passage. The outlet check valve 131 opens or closes the water outlet passage via an elastic component or the structure of the outlet check valve 131 itself. The elastic component can be a water outlet spring 133.

[0037] Among them, the water outlet cover 132 is detachably arranged on the water outlet of the water storage barrel 110. The water outlet component is detachable and can be used as a water inlet of the water storage device, which is also conducive to cleaning or replacement.

[0038] like Figure 7 As shown, to facilitate the connection between the water outlet cover 132 and the bottom of the water storage barrel 110, a water outlet connection pipe 110b is integrally formed at the bottom of the water storage barrel 110. The water outlet cover 132 and the water outlet connection pipe 110b are detachably connected. Similarly, there are various structures for detachable connection, such as threaded connection, snap-on connection, and bolt connection.

[0039] The water outlet one-way valve 131 passes through the water outlet cover 132, and the water outlet spring 133 is mounted on the water outlet one-way valve 131 located below the water outlet cover 132. The upper end of the water outlet one-way valve 131 is also a sealing structure. Unlike the air inlet channel one-way valve 121, the upper end of the water outlet one-way valve 131 is a sealing ring 131a, and the water outlet spring 133 forces the upper end of the water outlet one-way valve 131 to always seal the water outlet cover 132.

[0040] To facilitate the drainage of liquid into the drinking container 200 or the drinking water dish 230, the water outlet assembly 130 further includes a guide groove 134. The guide groove 134 is provided on the drinking container 200. The outlet check valve push rod 220 is disposed within the guide groove 134 and corresponds to the outlet check valve 131. The guide groove 134 extends toward the drinking container 200 and is located above the drinking container 200. The guide groove 134 can extend toward the drinking water dish 230 of the drinking container 200 or toward the drinking container 200.

[0041] When the water storage device 100 is installed on the drinking water container 200, the air inlet channel check valve 121 and the water outlet check valve 131 are both open. Initially, water flows out of the water outlet due to gravity. Then, air is taken in through the air inlet of the water storage tank due to negative pressure (air flows from the air inlet component 120 into the water storage tank 110). The liquid in the water storage tank 110 flows through the water outlet component 130 into the drinking water container 200. When the water level in the drinking water container 200 rises above the air inlet of the air inlet channel (covering the air inlet), the air inlet is closed, and no more air is taken into the water storage tank 110. Water is continuously sucked into the air inlet pipe 122 due to negative pressure, and water continues to flow out of the water outlet until the air pressure inside and outside the water storage tank 110 reaches equilibrium, at which point the water outlet stops flowing and the water level in the air inlet pipe 122 stops rising.

[0042] When the water level in the drinking water container 200 continues to drop until it reaches a certain distance below the air inlet of the air inlet passage, the water in the air inlet pipe 122 will fall into the drinking water container 200 and a small amount of air will enter the air inlet pipe until the water level in the air inlet pipe 122 reaches the same level as the water level in the drinking water container 200.

[0043] When the water level in the drinking water container 200 continues to drop and becomes lower than the air inlet of the air inlet channel, a large amount of air enters the air inlet channel and then enters the water storage device 100. The clean water in the water storage device flows from the water outlet into the drinking water container 200 due to gravity until a new balance is reached.

[0044] In this embodiment, Figure 8As shown, a circulating filter device 300 may be further provided in the drinking water container 200 to filter the liquid in the drinking water dish 230 of the drinking water container 200. The circulating filter device 300 in this embodiment includes a water pump 310 and a filter assembly 320. The water inlet of the water pump 310 is connected to the filter assembly 320 through a pipe, and the water outlet of the water pump 310 leads to the bottom of the drinking water dish 230. The bottom of the drinking water dish 230 is lower than the air inlet of the air inlet channel, and the dish opening of the drinking water dish 230 is higher than the air inlet of the air inlet channel. A through hole communicating with the filter assembly 320 is provided at the bottom of the drinking water dish 230. Initially, clean drinking water flows through the diversion channel 134 into the drinking container 200 or the drinking dish 230. This continues until the water level reaches a predetermined level, reaching equilibrium and no longer flowing out of the outlet. The water pump 310 then directs filtered drinking water to the drinking dish 230, raising the water level within the dish and allowing it to overflow into the drinking container 200. This reduces impurities such as hair and dust within the dish, ensuring the water in the dish remains clean. Because the through-hole at the bottom of the drinking dish 230 is connected to the filter assembly 320, all water that overflows from the drinking container 200 into the drinking dish 230 passes through the filter assembly 320. The filtered water from the water pump 310 is pumped toward the bottom of the drinking dish, creating a fountain-like flow within the dish 230, further facilitating the removal of hair, dust, and other impurities from the surface of the dish through the upper opening. More preferably, the water pump outlet can be located at the center of the top of the dish.

[0045] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand and implement the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to fall within the scope of protection of the present invention.
