20200337266
The present application claims the priority of China patent application No. 201820835018.7, filed May 31, 2018, and the priority of China patent application No. 201821472932.6, filed Sep. 7, 2018, the entire disclosures of which are hereby incorporated herein by reference.
The present disclosure relates to the technical field of pet appliances, for example, to a pet water dispenser.
As people's living standards significantly improve, they are also paying increasing attention to various supplies for pets which are now regarded as family members.
A pet water dispenser in the related art typically pumps water in a water storage tank to a drinking tray or a water outlet head using a water pump, and a pet can get drinking water from the drinking tray or the water outlet head. Typically, the entire water pump is arranged in the water storage tank for purposes of pumping water, and in order to meet the normal operation requirements of the water pump, it is necessary to provide a power supply cable connected to the water pump in the water storage tank from an external power supply.
Because the entire water pump and the power supply cable are required to be soaked in water to work for a long term, the water pump and the power supply line are vulnerable to water leaks thus affecting the normal operation of the water pump. More importantly, there are potential electricity leakage risks. Furthermore, much inconvenience is involved when a user needs to move the pet water dispenser.
This disclosure provides a pet water dispenser, whereby a stator of a water pump is no long soaked in water for long terms. Thus, electricity leakage is effectively avoided, which further enhances the safety.
The pet water dispenser includes a drinking tray disposed above a water storage tank, and a water pump configured to pump drinking water in the water storage tank to the drinking tray.
In Embodiment 1:
In Embodiment 2:
In the description of the present disclosure, unless otherwise expressly specified and defined, terms “connected to each other”, “connected” or “fixed” are to be construed in a broad sense, for example, as permanently connected, detachably connected, or integrated; mechanically connected or electrically connected; directly connected to each other or indirectly connected to each other via an intermediary; or internally connected or interactional between two components. For those skilled in the art, these terms in the present disclosure can be construed depending on specific context.
In the present disclosure, unless otherwise expressly specified and defined, when a first feature is described as “above” or “below” a second feature, the first feature and the second feature may be in direct contact, or may be in contact via another feature disposed between the two features. Furthermore, when the first feature is described as “on”, “above” or “over” the second feature, the first feature may be right on, above or over the second feature or may be obliquely on, above or over the second feature, or the first feature may be simply situated at a higher level than the second feature. When the first feature is described as “under”, “below” or “underneath” the second feature, the first feature may be right under, below or underneath the second feature or the first feature may be obliquely under, below or underneath the second feature, or the first feature may be simply situated at a lower level than the second feature.
The present embodiment provides a pet water dispenser, as illustrated in
In this embodiment, the configuration in which the stator accommodating groove 5 is disposed at the bottom of the water storage tank is only one implementation. Alternatively, the stator accommodating groove 5 may be disposed on a side wall of the water storage tank 1, while the rotor mounting bracket 4 may be disposed corresponding to the stator accommodating groove 5.
Typically, by disposing the rotor mounting bracket 4 for placing the rotor assembly 32 in the water storage tank 1 and disposing the stator accommodating groove 5 for placing the stator assembly 31 at a bottom or a side wall of the water storage tank 1, the stator assembly 31 of water pump 3 is no longer soaked in water for a long term, effectually avoiding electricity leakage, and thus improving safety.
As illustrated in
In addition, because the power supply assembly is also charged with electricity, in order to avoid a short circuit of the power supply assembly due to water leakage of the water storage tank 1 to affect the normal operation of the water pump 3, a power supply accommodating groove 6 for accommodating the power supply assembly is disposed on one side of the base 10 facing toward the water storage tank 1, so that the power supply assembly can be isolated from the water in the water storage tank 1, and the potential safety hazard of electric leakage is effectively eliminated. Furthermore, as the power supply assembly is integrally disposed in the power supply accommodating groove 6, and the base 10 is detachably connected to the water storage tank 1, when a user needs to move the pet water dispenser, inconvenience and potential safety hazards to the user caused by the exposed power cable can be prevented. In addition, the power supply assembly is disposed in the base 10, so that the power cable does not need to enter the water storage tank 1 from an opening at the upper part of the water storage tank 1, thereby improving the aesthetics of the whole pet water dispenser.
As illustrated in
After the drinking water in the water storage tank 1 is filtered by the filter assembly 9, the drinking water is pumped into the drinking water pipe assembly 7 by the water pump 3. Since the height of the water outlet head 8 is higher than that of the drinking tray 2, namely the water outlet head 8 is disposed above the drinking tray 2, the drinking water flowing through the drinking water pipe assembly 7 is sprayed from the water outlet head 8 and falls into the drinking tray 2. Because the drinking tray 2 is provided with a plurality of overflow through holes 21 along a circumference of the drinking tray 2, when the pet does not need a large amount of drinking water, the water in the drinking tray 2 can flow back into the water storage tank 1 through the overflow through holes 21 after the drinking tray 2 is full of water. The drinking water in the water storage tank 1 can be filtered and circulated, so that the cleanliness and quality requirements of the drinking water for pets can be ensured, and in the cases where no human intervention is present or a pet owner goes out, the drinking water can be automatically extracted by the water dispenser for the pets to drink.
In order to ensure uniform water distribution in the drinking tray 2, the drinking water pipe assembly 7 may be disposed at a center of the drinking tray 2. Meanwhile, a plurality of baffles (not shown in the figure) may be disposed on the water outlet head 8 at intervals along a circumference of the water outlet head 8, and the drinking water flowing through the drinking water pipe assembly 7 can be sprayed onto the drinking tray 2 from the spacing between two adjacent baffles, which not only improves the aesthetics and ornamental value, but also renders the drinking water sprayed onto the drinking tray 2 to be uniformly distributed.

As illustrated in
In addition to the above configuration, as illustrated in
The bottom wall of the water storage tank 1 is provided with a baseplate 11 detachably connected to the water storage tank 1 and a power supply accommodating groove 6 configured for accommodating components such as a power supply line, a power socket, a control circuit board and the like, where a space enclosed by the baseplate 11 and the water storage tank 1 is the stator accommodating groove 5. In an embodiment, the power socket, the stator assembly 31 and the circuit board are all disposed between the baseplate 11 and the bottom wall of the water storage tank 1.
In the present disclosure, the stator assembly 31 is configured to be encapsulated within the stator accommodating groove 5 by epoxy or another insulating material.
Adopting the epoxy or another insulating material to encapsulate the stator assembly 31 within the stator accommodating groove 5 has the following advantages. Firstly, the fixing effect on the stator assembly 31 can be achieved. Secondly, the stator assembly 31 can be isolated from the outside, so that a user can be prevented from being harmed in case electricity leakage of the stator assembly 31 occurs. Thirdly, the stator assembly 31 can be prevented from having a short circuit which would otherwise affect the normal operation of the water pump 3 when water leakage occurs with the water storage tank 1, thereby reducing potential safety hazards.
