[0003] Recently, pets are considered as members of the family and thus play the role of companions. Keepers manage pets by feeding or giving water to them.

[0004] In particular, pets need to drink water to maintain their biological rhythms. Due to the social lives of their owners, pets are often left alone at home, so a water supply device that can provide clean water to pets has been developed.

[0005] As such a conventional water supply device, Korean Patent Publication No. 10-20-0033132 is disclosed.

[0006] In the conventional water supply device, a water supply pipe and a water supply plate are provided in the inner center of the water tank. According to the above structure, the height of the water supply plate is increased, which may make it difficult for the pet to drink water. In addition, since foreign matter such as dust and hair may accumulate in the water tank, there is the inconvenience of having to frequently clean the water supply device. Summary of the invention

[0007] The present invention is proposed to solve the above problems, and its purpose is to provide a pet water supply device that can make pets drink water conveniently, can arouse pets' curiosity about water, and can minimize the accumulation of foreign matter on the upper surface of the top plate.

[0008] A pet water supply device of the present invention for achieving the above-mentioned purpose includes: a water tank for storing water; a pump for circulating the water in the water tank; a top plate, a discharge part and a water storage part are respectively formed on one side and the other side, and are formed to be wider from the one side to the other side, the discharge part is used to discharge the water supplied from the pump, and the water storage part is recessed and formed at a position lower than the discharge part in order to store the water discharged through the discharge part; a filter part is equipped to filter the water in the water storage part and then make it flow to the water tank; an upper shell body, on which the top plate is placed, so that water overflowing from the water storage part flows to the filter part through the space between the upper shell body and the top plate; a main body shell body surrounding the outside of the water tank; and a sensor part is placed, if the upper shell body is placed on the upper part of the main body shell body, power is supplied to the pump, if the upper shell body is removed from the main body shell body, the power supply to the pump is stopped.

[0009] According to the present invention, the position of the water storage part for storing water discharged from the discharge part can be lowered, so that the pet can drink water conveniently.

[0010] Also, the width of water flowing on the upper surface of the top plate can be maximized, thereby preventing foreign matter from being accumulated on the upper surface of the top plate.

[0011] Furthermore, the water is caused to overlap in a wave shape when flowing on the upper surface of the top plate, thereby arousing the curiosity of the pet and guiding the pet to drink a sufficient amount of water.

[0012] Furthermore, the top plate is configured to be inclined downward as it goes forward and to be wider as it goes forward, so that when the pet observes from the front, the flow of water can be clearly seen visually, thereby arousing curiosity and allowing the pet to drink water.

[0013] Furthermore, when the upper housing is not installed, the power supply to the light emitter and the pump is stopped, thereby protecting the eyes of the breeder from the light of the light emitter and preventing unnecessary operation of the pump.

[0023] Description of Reference Numerals DETAILED DESCRIPTION

[0024] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0025] Reference Figures 1 to 7 According to the present invention, the pet water supply device 1 includes: a water tank 150 for storing water; a pump 130 for circulating the water in the water tank 150; a top plate 120, a discharge portion 121 and a water storage portion 122 are respectively formed on one side and the other side, the discharge portion 121 is used to discharge the water supplied from the pump 130, and the water storage portion 122 is formed at a position lower than the discharge portion 121 in order to store the water discharged through the discharge portion 121; filter portions 141, 142 are equipped to filter the water in the water storage portion 122 and then make it flow to the water tank 150; a control portion 105 includes the pump 130 and is used to control the pet water supply device 1.

[0026] Hereinafter, when referring to directions, the side where the discharge portion 121 is located is referred to as the rear side, and the other side where the water storage portion 122 is located is referred to as the front side.

[0027] The water tank 150 is formed in a tub or box shape with an open top, so as to contain water in its inner space. The outer side of the water tank 150 is surrounded by the main body housing 100 .

[0028] The main body housing 100 has an open bottom surface, and a lower cover 101 is coupled to cover the open bottom surface of the main body housing 100 .

[0029] The main body housing 100 and the water tank 150 may be made of a synthetic resin material and integrally formed by injection molding. In this case, the upper end of the main body housing 100 and the upper end of the water tank 150 may be connected by a connection portion 102 .

[0030] The pump 130 operates to suck water stored in the water tank 150 and supply it to the water storage part 122 of the top plate 120. To this end, an inlet for water to flow into the pump 130 is connected to the water tank 150, and an outlet for discharging water from the pump 130 is connected to a water outlet pipe 131.

[0031] A pump inlet filter 133 for filtering water flowing into the pump 130 is provided between the inlet of the pump 130 and the water tank 150. The pump inlet filter 133 is formed to be recessed downward from the bottom 150a of the water tank 150, and is inserted and placed in the filter insertion part 150c opened at the bottom. A pump connection part 135 for connecting to the pump side is provided at the lower part of the filter insertion part 150c, and an O-ring 134 for maintaining airtightness is sandwiched between the bottom surface of the filter insertion part 150c and the pump connection part 135. Since the pump inlet filter 133 is provided, foreign matter can be prevented from flowing into the pump 130, thereby preventing the pump 130 from malfunctioning, and preventing noise from being generated when the pump 130 is working due to the inflow of foreign matter.

[0032] The water outlet pipe 131 is configured as a pipe having a length in the vertical direction, and the internal space 131a serves as a flow path for the water supplied by the pump 130. The lower end of the water outlet pipe 131 is connected to the pump 130, and the upper end 131b is connected to the discharge portion 121 of the top plate 120. The water outlet pipe 131 may be integrally formed on the outer side of the water tank 150.

[0033] When viewed in a plan view, the top plate 120 has a shape in which the width gradually widens from one side forming the discharge portion 121 to the other side forming the water storage portion 122, and is configured in a triangular shape with rounded corners. That is, it is configured in a shape in which the width at the rear is narrow and the width at the front is wide. Here, "width" refers to the width in the left-right direction perpendicular to the straight line connecting the front and the rear.

[0034] As described above, if the width of the top plate 120 is configured to gradually widen from the discharge portion 121 to the water storage portion 122, the width of the water discharged from the discharge portion 121 increases toward the water storage portion 122, so that the water discharged from the discharge portion 121 forms a larger width on the upper surface of the top plate 120 and flows.

[0035] According to this, even if pet hair, dust, etc. are accumulated on the upper surface of the top plate 120, they can be washed by the water flowing with a large width, so that the upper surface of the top plate 120 can be kept clean.

[0036] Furthermore, the top plate 120 is configured to be tilted downward from the one side to the other side, so that the portion where the discharge portion 121 is formed is higher and the portion where the water storage portion 122 is formed is located at a lower position than the discharge portion 121. If configured in the above-described shape, the position of the water storage portion 122 can be lowered, so that the pet can drink water conveniently.

[0037] The discharge portion 121 is concave to form a discharge space 121a therein, and is configured in a funnel shape with a wide upper area and a narrow lower area in the vertical direction, and the lower part is open to allow water supplied by the pump 130 to flow in. A predetermined amount of water supplied by the pump 130 can be accommodated in the discharge space 121a.

[0038] If the discharge portion 121 is only a through hole penetrating the top plate 120 without forming the discharge space 121a, water supplied by the pump 130 splashes into the upper space due to the discharge pressure while passing through the through hole, thereby causing water to splash outside the water supply device.

[0039] In the present invention, a discharge space 121a for accommodating water is formed in the discharge portion 121, so that if water flows into the discharge portion 121 through the water outlet pipe 131 with the help of the operation of the pump 130, a predetermined amount of water is accommodated in the discharge space 121a, and the accommodated water acts as a buffer to prevent the water that continuously flows into the discharge space 121a with the help of the operation of the pump 130 from splashing into the upper space.

[0040] The water discharged from the discharge portion 121 flows into the water storage portion 122 , and the water storage portion 122 is formed in a concave shape with a convex lower portion in order to store the water.

[0041] A flow portion 123 for allowing water discharged from the discharge portion 121 to flow toward the water storage portion 122 is formed between the discharge portion 121 and the water storage portion 122. The flow portion 123 may be formed in a shape that is inclined downward from the rear to the front, which is a flow direction of the water.

[0042] The flow portion 123 may be formed with a pair of protrusions 124 protruding upward in the width direction of the flow portion 123. In this embodiment, an example is given of a case where there are two protrusions 124, but one or more than three protrusions may be provided. Due to the protrusions 124, the water flowing down from the discharge portion 121 may pass over the protrusions 124 and rise like waves, thereby arousing curiosity and allowing the pet to drink water.

[0043] And, if Figure 5 As shown in (c), the flow portion 123 may be configured to have a high center portion and low side edge portions in the width direction. If configured as described above, water flowing from the discharge portion 121 toward the water storage portion 122 flows in a form that spreads to the side edge portions, and thus can flow as wide as possible on the upper surface of the top plate 120. Therefore, the upper surface of the top plate 120 can be cleaned and kept clean.

[0044] The protrusion 124 may be formed to have a longer length along the width direction of the top plate 120. In the case where there are multiple protrusions 124, the multiple protrusions may be formed to have different lengths from each other. Furthermore, in the case where there are two protrusions 124, the protrusion located in the front may be formed to be longer than the protrusion located in the rear. Furthermore, in the case where there are three or more protrusions 124, the length may be longer toward the front. If configured as described above, water may flow with as large a width as possible corresponding to the shape in which the width of the top plate 120 is increased.

[0045] The upper surface of the top plate 120 may be surface treated to increase the surface roughness. If the water discharged from the discharge portion 121 is to flow toward the water storage portion 122 with as large a width as possible, the water needs to be kept in a state of being widely spread in the width direction.

[0046] The smoother the upper surface of the top plate 120 is, the greater its hydrophobicity to water. Therefore, when the water discharged from the discharge portion 121 flows toward the water storage portion 122, it gathers close to the center line connecting the discharge portion 121 and the water storage portion 122, resulting in a phenomenon in which the width of the flowing water becomes smaller.

[0047] In order to prevent the phenomenon as described above, if surface treatment is performed to increase the roughness of the upper surface of the top plate 120 , the surface area contacted by water increases, and thus the hydrophilicity of the upper surface of the top plate 120 increases.

[0048] The upper surface of the top plate 120 may be surface treated by sand blasting. Sand blasting is a method of performing surface treatment by forcefully spraying water with polishing materials such as sand and steel shot onto the surface of a material using compressed air or other methods. Preferably, glass protrusions, which are particles of a glass material, are used as the abrasive material for surface treatment.

[0049] The top plate 120 can be made of synthetic resin or stainless steel. When the top plate 120 is made of stainless steel, the risk of bacterial growth is low, thereby preventing the pet from contact allergies and acne.

[0050] The water outlet pipe 131 is connected to the discharge portion 121 via a discharge portion connecting component 132 .

[0051] The discharge part connecting component 132 includes a discharge part coupling portion 132a coupled to the lower end of the discharge part 121, a water outlet pipe coupling portion 132b coupled to the upper end 131b of the water outlet pipe 131, and a through hole 132c penetrating the central portion of the discharge part coupling portion 132a and the water outlet pipe coupling portion 132b from top to bottom.

[0052] The discharge unit coupling part 132a is formed in an elliptical plate shape, and a recessed part 132e is formed along the outer periphery of the discharge unit coupling part 132a so as to be recessed inward. The lower end part 121b of the discharge unit 121 is inserted into the recessed part 132e to be locked, thereby achieving the coupling of the discharge unit connecting member 132 and the discharge unit 121.

[0053] The outlet pipe joint part 132b is formed in the shape of a pipe extending downward from the lower end of the discharge part joint part 132a. A lower end protrusion 132f protruding outward is formed around the lower end of the outlet pipe joint part 132b, and the lower end protrusion 132f is locked in the outlet pipe protrusion 131c protruding inward from the inner side of the upper end of the outlet pipe 131, thereby realizing the connection between the outlet part connection component 132 and the outlet pipe 131. In the state where the outlet part connection component 132 is connected to the top plate 120, if the lower end protrusion 132f of the outlet part connection component 132 is connected to the outlet pipe protrusion 131c of the outlet pipe 131, the top plate 120 will not move and the position is fixed.

[0054] As the upper surface of the discharge portion joint portion 132a, a discharge portion protruding piece 132d protruding upward more than the upper surface of the top plate 120 is formed at the end portion on the opposite side of the water storage portion 122 with the through hole 132c as a reference.

[0055] The discharge portion protrusion piece 132d is formed in a thumb shape to facilitate grasping by hand, and is concave toward the water storage portion 122, while the opposite side surface is formed convex.

[0056] The discharge portion protrusion piece 132d performs the function of a handle to facilitate the separation of the top plate 120 and the discharge portion connection member 132 from the water outlet pipe 131. In addition, the discharge portion protrusion piece 132d performs the function of guiding the water passing through the through hole 132c and the discharge space 121a to flow to the front where the water storage portion 122 is located and blocking the water from flowing to the rear which is the opposite direction.

[0057] A pair of protrusions 132g having a horizontal length and protruding forward may be formed on the front surface of the discharge portion protruding piece 132d. The protrusions 132g are provided so that it is easy to grasp and pull upwards.

[0058] In this embodiment, the discharge portion protruding piece 132d is formed integrally with the discharge portion connecting member 132, but the discharge portion protruding piece 132d may be configured to protrude upward from the upper surface of the top plate 120 at a position behind the discharge portion 121 on the opposite side of the discharge portion 121 with respect to the discharge portion 121. Even with the configuration as described above, it is possible to block the water passing through the through hole 132c and the discharge space 121a from flowing backward, and it is also possible to perform a handle function for separating the top plate 120 from the water outlet pipe 131.

[0059] The filter parts 141 and 142 are used to filter foreign matter before the water overflowing from the water storage part 122 of the top plate 120 flows into the water tank 150 , and include a primary filter 141 and a secondary filter 142 for secondary filtering the water passing through the primary filter 141 .

[0060] The primary filter 141 is used to filter larger foreign matter such as pet hair, and may be formed using a pre-filter.

[0061] The secondary filter 142 may be formed of non-woven fabric and activated carbon, and may be formed of a filter that removes fine particles and residual chlorine.

[0062] An upper housing 110 is provided on the upper portion of the main housing 100 , on which the top plate 120 is placed and for supporting the filter units 141 and 142 .

[0063] The upper shell 110 includes: a main body 111, which is configured to have a shape corresponding to the shape of the top plate 120 to place the top plate 120; a shell flange 112, which extends downward around the edge of the main body 111; and a filter support portion 113, which is formed in the central portion of the main body 111 and supports the filter portions 141 and 142.

[0064] The main body 111 may be configured to have a shape that is inclined downward from the rear to the front in a manner corresponding to the shape of the top plate 120 , and may include a side wall 111 b that extends upward around an edge portion.

[0065] The side wall portion 111 b corresponds to the shape of the top plate 120 , so that the top plate 120 is arranged in an inner space surrounded by the main body portion 111 and the side wall portion 111 b .

[0066] A plurality of mounting protrusions 111a for supporting the bottom surface of the top plate 120 protrude upward from both front and rear sides of the main body 111. If the bottom surface of the top plate 120 is mounted on the mounting protrusions 111a, the bottom surface of the top plate 120 is separated from the upper surface of the main body 111.

[0067] If the water stored in the water storage portion 122 of the top plate 120 overflows from the edge of the top plate 120 , the water flows through the space between the bottom surface of the top plate 120 and the upper surface of the body portion 111 .

[0068] If the upper housing 110 is placed on the main housing 100 , the lower end of the housing flange 112 is supported by the upper surface edge of the main housing 100 .

[0069] The filter support portion 113 is formed by recessing the central portion of the main body 111 downward, and is configured in a circular shape corresponding to the primary filter 141 and the secondary filter 142. A plurality of through holes 113a are formed in the filter support portion 113 so that water passing through the primary filter 141 flows toward the secondary filter 142.

[0070] The primary filter 141 is disposed on the upper surface of the filter support portion 113 , and the secondary filter 142 is coupled to the bottom surface of the filter support portion 113 .

[0071] The top plate 120, the upper shell 110, the primary filter 141 and the secondary filter 142 are formed into a stacked structure, so they can be disassembled and assembled by simple operations. Therefore, the breeder can conveniently disassemble and clean the components, and can easily replace the primary filter 141 and the secondary filter 142.

[0072] A water outlet pipe through hole 114 through which an upper end portion 131 b of the water outlet pipe 131 passes is formed at the rear of the main body 111 .

[0073] A plurality of overflow prevention holes 115 are formed at both sides of the central portion of the main body 111. The overflow prevention holes 115 may be located higher than the primary filter 141 and may be formed at a position lower than the upper end of the side wall 111b.

[0074] If the primary filter 141 or the secondary filter 142 is clogged, water overflowing from the water storage portion 122 of the top plate 120 fills the space surrounded by the main body 111 and the side wall 111b, and if the water level exceeds the upper end of the side wall 111b, the water overflows to the outside of the main body housing 100. In the case of the present invention, since the overflow prevention hole 115 is formed, even if the upper part of the main body 111 is filled with water, the water will fall into the water tank 150 through the overflow prevention hole 115, thereby preventing the water from overflowing to the outside of the main body housing 100.

[0075] A partition space is formed between the water tank 150, the main body housing 100, and the lower cover 101. The pump 130, a sterilizing unit 161 for sterilizing water in the inner space of the water tank 150, a battery 163 for supplying power, a water level sensor 164 for sensing the water level in the water tank 150, and a control unit 105 are arranged in the partition space.

[0076] The sterilizing unit 161 may be formed by an LED that irradiates ultraviolet light to the inner space of the water tank 150. Preferably, the sterilizing unit 161 may be formed by using UV-C having a wavelength excellent in sterilizing power among the types of ultraviolet light.

[0077] The sterilization section 161 includes: a fixed shell 161d, fixed to the bottom surface of the bottom 150a of the water tank 150; a substrate 161a, fixed to the lower part of the fixed shell 161d by a fastening component 161e and equipped with an LED as a light-emitting body; a transmission component 161b, which is made of glass so that the light of the light-emitting body can be transmitted to the internal space of the water tank 150; a sealing component 161c, which is sandwiched between the edge of the transmission component 161b and the inner side surface of the fixed shell 161d to prevent water in the water tank 150 from leaking to the substrate 161a side.

[0078] A pair of bosses 150b protruding downward are formed on the bottom surface of the bottom 150a of the water tank 150, and the two side ends of the fixed housing 161d are connected to the bosses 150b by fastening components (not shown). The fixed housing 161d is inserted into a through hole 150d formed in the bottom 150a of the water tank 150.

[0079] An opening 161f is formed at the upper center of the fixed housing 161d and communicates with the inner space of the water tank 150. The light emitter of the substrate 161a is disposed below the opening 161f. When the sterilizing unit 161 is operated, ultraviolet light emitted from the light emitter is irradiated to the water inside the water tank 150 through the opening 161f, thereby sterilizing the water contained in the water tank 150.

[0080] The upper surface of the transmissive member 161b contacts the water in the water tank 150 filled in the opening 161f, and the transmissive member 161b blocks the water to prevent the water in the opening 161f from falling toward the substrate 161a, while transmitting the light of the light emitter.

[0081] An O-ring 162 may be interposed between the inner side surface of the boss 150 b and the outer side surface of the fixed housing 161 d to prevent water in the water tank 150 from leaking to the lower portion of the sterilization unit 161 .

[0082] The battery 163 may be configured using a rechargeable battery, so that the pet water supply device 1 can be operated without a separate power supply. As described above, if the battery 163 is provided, a cable for power connection is not required as a wireless method, so that the pet water supply device 1 can be placed at a desired location for use. In addition to the battery 163, the pet water supply device 1 may be configured to receive power from an external source to operate.

[0083] The water level sensor 164 is used to sense whether the water in the water tank 150 is lower than a set water level and is in a water shortage state. If the pump 130 is operated in a water shortage state, the life of the pump 130 may be shortened. Therefore, the control unit controls the pump 130 to operate only when the water level is above the water level set by the water level sensor 164.

[0084] The water level sensor 164 is a non-contact type. If the water inside the water tank 150 drops to a set water level, the resistance value sensed by the water level sensor 164 changes. If it is determined that the water level is lower than the set water level according to the changed resistance value, the operation of the pump 130 is stopped. In this case, a warning indicating a low water level can be issued.

[0085] If the pump 130 is operated in a state where the upper housing 110 is not placed on the upper part of the main housing 100, the water supplied from the pump 130 is directly discharged through the water outlet pipe 131, and thus the discharged water may escape to the outside of the main housing 100. In addition, in a state where the upper housing 110 is not placed on the upper part of the main housing 100, if the luminous body of the sterilizing part 161 emits light, the light of the luminous body may directly irradiate the eyes of the breeder after passing through the inside of the water tank 150. Therefore, preferably, in a state where the upper housing 110 is not placed on the upper part of the main housing 100, the power supply is stopped so that the pump 130 and the luminous body do not operate.

[0086] To this end, a seating sensing portion 170 for sensing whether the upper housing 110 is seated on the upper portion of the main housing 100 is provided.

[0087] If the placement sensor 170 senses that the upper housing 110 is placed on the upper part of the main housing 100, power is supplied to operate the pump 130 and the light emitter. If the placement sensor 170 senses that the upper housing 110 is not placed on the upper part of the main housing 100, power supply is stopped to stop the pump 130 and the light emitter from operating. In this case, the power supply to the entire pet water supply device 1 may be stopped, but only the power supply to the pump 130 and the light emitter may be stopped.

[0088] The seating sensing part 170 may include a magnet 171 and a magnet sensing part 172 for sensing a change in magnetic flux according to movement of the magnet 171 .

[0089] The magnet 171 is coupled to the bottom surface of the upper housing 110, and the magnet sensing unit 172 is coupled to the main housing 100. If the upper housing 110 falls off from the main housing 100, the magnet sensing unit 172 senses the falling off of the magnet 171, and the control unit stops supplying power to the pump 130 and the light emitter. If the upper housing 110 is placed on the upper part of the main housing 100, the magnet sensing unit 172 senses the magnet 171, and the control unit supplies power to the pump 130 and the light emitter.

[0090] The magnet sensing unit 172 may be configured using an MR sensor that senses a change in a magnetic field according to movement of the magnet 171 or a reed switch that is turned on / off according to movement of the magnet 171 .

[0091] An ambient light 181 that emits light may be provided in front of the main body housing 100. The light emitted from the ambient light 181 may arouse the curiosity of the pet, thereby guiding the pet to the pet water supply device 1 so that the pet can drink water.

[0092] Reference Figure 8 , a control method of the pet water supply device 1 is described.

[0093] As control modes of the pet water supply device 1 , a first mode in which the pump 130 is continuously operated to continuously circulate water without stopping, and a second mode in which the pump 130 is repeatedly operated for a first set time and stopped for a second set time can be set.

[0094] The second mode can be implemented in a plurality of modes by variously changing the first set time and the second set time.

[0095] When the pump 130 is operated, water in the water tank 150 flows into the inlet of the pump 130 through the pump inlet filter 133 , and water discharged through the outlet of the pump 130 passes through the outlet pipe 131 and then is discharged to the upper part of the top plate 120 through the discharge part 121 .

[0096] In this case, a predetermined amount of water is stored in the discharge space 121 a of the discharge portion 121 , thereby playing a buffering role to prevent the water continuously flowing into the discharge space 121 a from splashing toward the upper space.

[0097] The water discharged from the discharge portion 121 is prevented from flowing backward by the discharge portion protruding piece 132d and is guided to flow forward where the water storage portion 122 is located.

[0098] The water discharged from the discharge portion 121 flows toward the water storage portion 122 through the flow portion 123 . Preferably, the water discharged from the discharge portion 121 can flow to the water storage portion 122 on the upper surface of the top plate 120 with as wide an area or as wide a width as possible.

[0099] The top plate 120 is configured to have a shape in which the width widens from one side where the discharge portion 121 is formed to the other side where the water storage portion 122 is formed. In addition, the top plate 120 may be configured to have a shape that is inclined downward from the one side to the other side, and a pair of protrusions 124 that protrude upwardly and long in the width direction may be formed on the flow portion 123 of the top plate 120. In addition, the upper surface of the top plate 120 may be surface-treated to increase the surface roughness. Due to such a configuration, water flows on the upper surface of the top plate 120 in a form that is widely spread in the width direction.

[0100] Furthermore, the pump 130 may be controlled to operate at a first output at an initial operation stage, and then, if a set condition is satisfied, to operate at a second output lower than the first output. In this case, the set condition may be a set time.

[0101] If the control is performed as described above, the water can be formed to have a wide width by operating at the first output having a higher output in the initial stage, so that a large amount of water is discharged from the discharge portion 121 and passes through the flow portion 123. Thereafter, after a set time has passed, even if the output of the pump 130 is reduced to the second output, the water can be formed to have a wide width due to the shape and surface treatment of the top plate 120.

[0102] In addition, when water flows over the protrusions 124, it appears as a wave-like state, thereby arousing curiosity and allowing the pet to drink water.

[0103] Furthermore, the top plate 120 is configured to be inclined downward and wider toward the front, so that when the pet observes from the front, the flow of water can be clearly seen visually, thereby arousing curiosity and allowing the pet to drink water.

[0104] In addition, since water flows while maintaining a large width on the upper surface of the top plate 120 , accumulation of impurities on the upper surface of the top plate 120 can be minimized.

[0105] If the water storage portion 122 stores water and exceeds the water storage capacity, the water overflows over the edge of the top plate 120. The water overflowing from the water storage portion 122 flows toward the upper surface of the main body 111 of the upper housing 110 through the gap between the edge of the top plate 120 and the inner side surface of the side wall portion 111b of the upper housing 110, and then passes through the filter portions 141 and 142.

[0106] The water after the foreign matter is filtered out by the filter units 141 and 142 is stored in the water tank 150 and then continues to circulate by the pump 130 .

[0107] Although the present invention has been described in detail by enumerating preferred embodiments as described above, the present invention is not limited to the above embodiments, and can be implemented in various modifications within the scope of the claims, the detailed description of the present invention, and the drawings, and these modifications belong to the present invention.
