Description

Technical Field

[0001] The present invention relates to a water supply device for pets, and more particularly to a water supply device for pets that enables pets to drink water conveniently and prevents foreign substances from accumulating on the upper surface of the top plate. Background Art

[0002] Recently, pets are regarded as a member of the family and thus play the role of a companion. Breeders feed or water the pets to manage them.

[0003] In particular, pets need to drink water to maintain their biological rhythms. Due to the social life of breeders, pets are often left alone at home, so a water supply device that can provide clean water to pets has been developed.

[0004] As such an existing water supply device, Korean Patent Publication No. 10-20-0033132 is disclosed.

[0005] For the existing water supply device, a water supply pipe and a water supply plate are provided at the central portion inside the water tank. According to the above structure, since the height of the water supply plate increases, it may be difficult for pets to drink water. In addition, since foreign substances such as dust and hair may accumulate in the water tank, there is an inconvenience that the water supply device must be frequently cleaned. Summary of the Invention

[0006] The present invention is proposed to solve the above problems, and its purpose is to provide a water supply device for pets that enables pets to drink water conveniently, can arouse the curiosity of pets about water, and can minimize the accumulation of foreign substances on the upper surface of the top plate.

[0007] A water supply device for pets according to the present invention for achieving the above object 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 formed on one side and the other side respectively, and are formed to be wider from the one side to the other side, the discharge part for discharging the water supplied from the pump, the water storage part is recessed to form at a position lower than the discharge part in order to store the water discharged through the discharge part; a filter part configured to filter the water in the water storage part and then make it flow into the water tank.

[0008] According to the present invention, the position of the water storage part for storing the water discharged from the discharge part can be lowered, so that pets can drink water conveniently.

[0009] In addition, the width of the water flowing on the upper surface of the top plate can be maximized, thereby preventing foreign substances from accumulating on the upper surface of the top plate.

[0010] In addition, when the water flows on the upper surface of the top plate, it forms waves, thereby arousing the curiosity of pets and guiding pets to drink a sufficient amount of water.

[0011] Moreover, the top plate is configured to be inclined downward more as it goes forward and to have a greater width as it goes forward, so that when the pet observes from the front, the flowing water can be clearly seen visually, thus arousing curiosity and enabling the pet to drink water.

[0012] Moreover, 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.

[0013] Moreover, an overflow prevention hole is provided, so that even when the filter part is clogged, water can be prevented from overflowing to the outside of the water supply device. Description of the Drawings

[0048] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0049] Referring to Figures 1 to 7 , the water supply device 1 for pets according to the present invention includes: a water tank 150 for storing water; a pump 130 for circulating the water in the water tank 150; a top plate 120 having a discharge part 121 and a water storage part 122 formed on one side and the other side respectively, the discharge part 121 for discharging the water supplied from the pump 130, and the water storage part 122 formed at a position lower than the discharge part 121 for storing the water discharged through the discharge part 121; filter parts 141, 142 configured to filter the water in the water storage part 122 and then make it flow into the water tank 150; and a control part 105 including the pump 130 and configured to control the water supply device 1 for pets.

[0050] Hereinafter, when referring to directions, the side where the discharge part 121 is located will be referred to as the rear, and the other side where the water storage part 122 is located will be referred to as the front.

[0051] The water tank 150 is configured in the shape of an open-top bucket or box so as to store water in its internal space. The outside of the water tank 150 is surrounded by the main body housing 100.

[0052] The bottom surface of the main body housing 100 is open, and a lower cover 101 is coupled in a manner to cover the open bottom surface of the main body housing 100.

[0053] 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 portions of the main body housing 100 and the water tank 150 may be connected by a connecting part 102.

[0054] The pump 130 operates to suck the water stored inside the water tank 150 and supply it to the water storage part 122 of the top plate 120. For this purpose, an inlet for allowing 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 discharge pipe 131.

[0055] A pump inlet filter 133 for filtering the 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 disposed in a filter insertion part 150c that is open at the lower part. A pump connection member 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 interposed between the bottom surface of the filter insertion part 150c and the pump connection member 135. Since the pump inlet filter 133 is provided, foreign substances can be prevented from flowing into the pump 130, thereby preventing the occurrence of failures of the pump 130, and noise generated during the operation of the pump 130 due to the inflow of foreign substances can also be prevented.

[0056] The water outlet pipe 131 is configured in a pipe shape having a length in the vertical direction, and an internal space 131a serves as a flow path through which the water supplied by the pump 130 flows. 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 part 121 of the top plate 120. The water outlet pipe 131 can be integrally formed outside the water tank 150.

[0057] When viewed in a plan view, the top plate 120 has a shape in which the width gradually becomes wider from the side where the discharge part 121 is formed to the other side where the water storage part 122 is formed, and is configured in a triangular shape with rounded corners. That is, it is configured in a shape where the width at the rear is narrow and the width at the front is wide. Here, the "width" refers to the width in the left-right direction perpendicular to the straight line connecting the front and the rear.

[0058] As described above, if the width of the top plate 120 is configured to gradually become wider from the discharge part 121 to the water storage part 122, the width of the water discharged from the discharge part 121 becomes larger as it goes toward the water storage part 122, so that the water discharged from the discharge part 121 flows on the upper surface of the top plate 120 with a larger width.

[0059] Accordingly, even if pet hair, dust, etc. accumulate on the upper surface of the top plate 120, the upper surface of the top plate 120 can be cleaned by the water flowing with a larger width, so that the upper surface of the top plate 120 is kept clean.

[0060] In addition, the top plate 120 is configured to be inclined downward from the one side to the other side, so that the part where the discharge part 121 is formed is higher and the part where the water storage part 122 is formed is located at a position lower than the discharge part 121. If configured in the above-described shape, the position of the water storage part 122 can be lowered, thereby making it convenient for pets to drink water.

[0061] The discharge part 121 has a concave shape to form a discharge space 121a inside, and is configured in a funnel shape with a wider upper area and a narrower lower area in the vertical direction, and the lower part is open so that the water supplied by the pump 130 can flow in. A predetermined amount of the water supplied by the pump 130 can be accommodated in the discharge space 121a.

[0062] If the discharge part 121 does not form the discharge space 121a but is only configured as a through-hole penetrating the top plate 120, the water supplied by the pump 130 splashes into the upper space due to the discharge pressure while passing through the through-hole, resulting in the phenomenon that the water scatters to the outside of the water supply device.

[0063] In the present invention, a discharge space 121a for accommodating water is formed in the discharge part 121. Thus, if the water flows into the discharge part 121 through the water outlet pipe 131 by the operation of the pump 130, a predetermined amount of water is accommodated in the discharge space 121a, and the accommodated water serves as a buffer to prevent the water continuously flowing into the discharge space 121a due to the operation of the pump 130 from splashing into the upper space.

[0064] The water discharged from the discharge part 121 flows toward the water storage part 122, and the water storage part 122 is formed in a concave shape with a lower protrusion to store the water.

[0065] A flow part 123 is formed between the discharge part 121 and the water storage part 122 to allow the water discharged from the discharge part 121 to flow toward the water storage part 122. The flow part 123 can be formed in a shape that slopes downward from the rear to the front in the water flow direction.

[0066] A pair of protrusions 124 protruding upward in the width direction of the flow part 123 can be formed in the flow part 123. In this embodiment, the case where the protrusions 124 are two is illustrated, but it can also be configured with one or three or more. Due to the protrusions 124, the water flowing down from the discharge part 121 can rise like a wave over the protrusions 124, which can arouse curiosity and enable pets to drink water.

[0067] And, as shown in (c) of Figure 5 The flow part 123 can be configured to have a higher central part and lower side edge parts in the width direction. If configured as above, the water flowing from the discharge part 121 toward the water storage part 122 flows in a form that spreads to the side edge parts, so it can flow with the largest possible width on the upper surface of the top plate 120. Therefore, the upper surface of the top plate 120 can be cleaned and maintained in a clean state.

[0068] The protrusion 124 can be formed to have a relatively long length in the width direction of the top plate 120. In the case where there are a plurality of protrusions 124, the plurality of protrusions can be formed to have different lengths from each other. Also, in the case where there are two protrusions 124, the protrusion located in the front can be formed to have a longer length than the protrusion located in the rear. Further, in the case where there are three or more protrusions 124, they can be formed to have longer lengths as they are closer to the front. If configured as described above, corresponding to the shape in which the width of the top plate 120 increases, water can flow with as large a width as possible.

[0069] The upper surface of the top plate 120 can be surface-treated to increase surface roughness. If water discharged from the discharge part 121 is to flow toward the water storage part 122 with as large a width as possible, the water needs to maintain a form that spreads relatively widely in the width direction.

[0070] The smoother the upper surface of the top plate 120, the greater the hydrophobicity to water. Thus, when water discharged from the discharge part 121 flows toward the water storage part 122, it gathers in a manner closer to the center line connecting the discharge part 121 and the water storage part 122, resulting in a phenomenon where the width of the flowing water becomes smaller.

[0071] To prevent the above-described phenomenon, if surface treatment is performed to increase the roughness of the upper surface of the top plate 120, the surface area in contact with water increases, thereby increasing the hydrophilicity of the upper surface of the top plate 120.

[0072] The upper surface of the top plate 120 can be surface-treated by blasting. Blasting is a method of surface treatment in which water added with polishing materials such as sand and steel shot is strongly sprayed onto the surface of the material using compressed air or other methods. Preferably, glass beads made of glass material are used as the abrasive material for surface treatment.

[0073] The top plate 120 can be made of synthetic resin or stainless steel. In the case where the top plate 120 is made of stainless steel, the risk of bacterial growth is relatively low, thus preventing contact allergies and acne in pets.

[0074] The water outlet pipe 131 and the discharge part 121 are connected by a discharge part connecting member 132.

[0075] The discharge part connecting member 132 includes a discharge part engaging portion 132a engaged with the lower end portion of the discharge part 121, a water outlet pipe engaging portion 132b engaged with the upper end portion 131b of the water outlet pipe 131, and a through hole 132c penetrating the central portions of the discharge part engaging portion 132a and the water outlet pipe engaging portion 132b vertically.

[0076] The discharge unit coupling part 132a is configured in an elliptical plate shape, and a recessed part 132e that is recessed inward is formed along the outer periphery of the discharge unit coupling part 132a. The lower end part 121b of the discharge unit 121 is inserted into the recessed part 132e to achieve locking, thereby realizing the coupling of the discharge unit connecting member 132 and the discharge unit 121.

[0077] The water outlet pipe coupling part 132b is configured in a pipe shape that extends downward from the lower end of the discharge unit coupling part 132a. A lower end protruding part 132f that protrudes outward is formed around the lower end part of the water outlet pipe coupling part 132b, and the lower end protruding part 132f is locked to a water outlet pipe protruding part 131c that protrudes inward from the inner side surface of the upper end part of the water outlet pipe 131, thereby realizing the coupling of the discharge unit connecting member 132 and the water outlet pipe 131. In a state where the discharge unit connecting member 132 is coupled to the top plate 120, if the lower end protruding part 132f of the discharge unit connecting member 132 is coupled to the water outlet pipe protruding part 131c of the water outlet pipe 131, the top plate 120 will not move and will be fixed in position.

[0078] As the upper surface of the discharge unit coupling part 132a, with the through hole 132c as a reference, a discharge unit protruding piece 132d that protrudes upward more than the upper surface of the top plate 120 is formed at the opposite side end of the water storage part 122.

[0079] The discharge unit protruding piece 132d is configured in a thumb shape for easy grasping by hand, and the surface facing the water storage part 122 is recessed, and the opposite side surface is formed to protrude.

[0080] The discharge unit protruding piece 132d functions as a handle to easily separate the top plate 120 and the discharge unit connecting member 132 from the water outlet pipe 131 together. In addition, the discharge unit protruding piece 132d functions to guide the water passing through the through hole 132c and the discharge space 121a to flow forward to the location of the water storage part 122 and block the flow in the opposite direction, which is the rear.

[0081] On the front surface of the discharge unit protruding piece 132d, a pair of protrusions 132g that have a horizontal length and protrude forward can be formed in the up and down direction. Due to the provision of the protrusions 132g, it is easy to grasp with the hand and pull upward.

[0082] In this embodiment, a configuration in which the discharge portion protruding piece 132d and the discharge portion connecting member 132 are integrally formed is illustrated as an example. However, the discharge portion protruding piece 132d may also 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 as a reference. Even if configured as described above, it is possible to block the backward flow of water passing through the through hole 132c and the discharge space 121a, and it is also possible to perform a handle function for separating the top plate 120 from the water discharge pipe 131.

[0083] The filter units 141 and 142 are configured to filter foreign matters before the water overflowing from the water storage unit 122 of the top plate 120 flows into the water tank 150, and include a primary filter 141 and a secondary filter 142 for performing secondary filtration on the water passing through the primary filter 141.

[0084] The primary filter 141 is configured to filter relatively large foreign matters such as pet hair, and may be configured using a pre-filter.

[0085] The secondary filter 142 may be configured using non-woven fabric and activated carbon, and is configured using a filter for removing fine particles and residual chlorine.

[0086] At the upper portion of the main body housing 100, an upper housing 110 is provided, on which the top plate 120 is disposed and which is configured to support the filter units 141 and 142.

[0087] The upper housing 110 includes: a main body portion 111 configured to have a shape corresponding to the shape of the top plate 120 to dispose the top plate 120; a housing flange 112 extending downward along the periphery of the main body portion 111; and a filter support portion 113 formed at the central portion of the main body portion 111 to support the filter units 141 and 142.

[0088] The main body portion 111 may be configured to have a shape that slopes downward from the rear to the front corresponding to the shape of the top plate 120, and a side wall portion 111b extending upward along the peripheral portion is formed.

[0089] The side wall portion 111b corresponds to the shape of the top plate 120, so that the top plate 120 is disposed in the internal space surrounded by the main body portion 111 and the side wall portion 111b.

[0090] A plurality of placement protrusions 111a for supporting the bottom surface of the top plate 120 protrude upward from both the front sides and the rear sides of the main body portion 111. If the bottom surface of the top plate 120 is placed on the placement protrusions 111a, the bottom surface of the top plate 120 is spaced apart from the upper surface of the main body portion 111.

[0091] If the water stored in the water storage part 122 of the top plate 120 overflows through the edge of the top plate 120, it flows through the separation space between the bottom surface of the top plate 120 and the upper surface of the main body part 111.

[0092] If the upper housing 110 is placed on the main body housing 100, the lower end of the housing flange 112 is supported by the edge of the upper surface of the main body housing 100.

[0093] The filter support part 113 is formed by recessing the central part of the main body part 111 downward, and is configured as a circle corresponding to the shape of the primary filter 141 and the secondary filter 142. A plurality of through holes 113a are formed in the filter support part 113 to allow the water passing through the primary filter 141 to flow to the secondary filter 142.

[0094] The primary filter 141 is placed on the upper surface of the filter support part 113, and the secondary filter 142 is coupled to the bottom surface of the filter support part 113.

[0095] The top plate 120, the upper housing 110, the primary filter 141 and the secondary filter 142 are configured in a vertically 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.

[0096] An outlet pipe through hole 114 through which the upper end 131b of the outlet pipe 131 penetrates is formed at the rear of the main body part 111.

[0097] A plurality of water overflow prevention holes 115 are formed on both sides of the central part of the main body part 111. The water overflow prevention holes 115 can be located at a position higher than the primary filter 141, and can be formed at a position lower than the upper end of the side wall part 111b.

[0098] If the primary filter 141 or the secondary filter 142 is blocked, the water overflowing from the water storage part 122 of the top plate 120 fills the space surrounded by the main body part 111 and the side wall part 111b. If the water level exceeds the upper end of the side wall part 111b, the water overflows to the outside of the main body housing 100. In the case of the present invention, since the water overflow prevention holes 115 are formed, even if the upper part of the main body part 111 is filled with water, the water will fall into the inside of the water tank 150 through the water overflow prevention holes 115, thereby preventing the water from overflowing to the outside of the main body housing 100.

[0099] A separation space is formed between the water tank 150, the main body housing 100, and the lower cover 101. The pump 130, a sterilization unit 161 for sterilizing the water in the internal space of the water tank 150, a battery 163 for supplying power, a water level sensor 164 for sensing the water level inside the water tank 150, and a control unit 105 are provided in the separation space.

[0100] The sterilization unit 161 may be constituted by an LED that irradiates ultraviolet rays into the internal space of the water tank 150. Preferably, it is constituted by UV-C having a wavelength with excellent sterilizing power among the types of ultraviolet rays.

[0101] The sterilization unit 161 includes: a fixed housing 161d fixed to the bottom surface 150a of the bottom of the water tank 150; a substrate 161a fixed to the lower part of the fixed housing 161d by a fastening member 161e and provided with an LED as a light-emitting body; a transmissive member 161b made of glass so that the light of the light-emitting body is transmitted to the internal space of the water tank 150; and a sealing member 161c interposed between the periphery of the edge of the transmissive member 161b and the inner side surface of the fixed housing 161d to prevent the water in the water tank 150 from leaking to the substrate 161a side.

[0102] A pair of bosses 150b protruding downward are formed on the bottom surface of the bottom 150a of the water tank 150, and both end portions of the fixed housing 161d are coupled to the bosses 150b by fastening members (not shown). The fixed housing 161d is inserted into a through hole 150d formed in the bottom 150a of the water tank 150.

[0103] An opening 161f communicating with the internal space of the water tank 150 is formed in the upper center of the fixed housing 161d, and the light-emitting body of the substrate 161a is provided below the opening 161f. When the sterilization unit 161 operates, the ultraviolet light emitted from the light-emitting body is irradiated onto the water inside the water tank 150 through the opening 161f, thereby sterilizing the water accommodated in the water tank 150.

[0104] The upper surface of the transmissive member 161b is in contact with the water in the water tank 150 filling the opening 161f, and the transmissive member 161b blocks the water to prevent the water in the opening 161f from falling onto the substrate 161a while transmitting the light of the light-emitting body.

[0105] An O-ring 162 may be interposed between the inner side surface of the boss 150b and the outer side surface of the fixed housing 161d to prevent the water inside the water tank 150 from leaking to the lower part of the sterilization unit 161.

[0106] The battery 163 can be 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, in a wireless manner, there is no need for a cable for power connection, so that the pet water supply device 1 can be placed at a desired position for use. In addition to the battery 163, it can also be configured to receive power from the outside to operate the pet water supply device 1.

[0107] The water level sensor 164 is used to sense whether the water in the water tank 150 is lower than the set water level and is in a water shortage state. If the pump 130 operates in a water shortage state, problems such as shortening the life of the pump 130 may occur. 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.

[0108] The water level sensor 164 is a non-contact type. If the water in the water tank 150 drops to the 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 based on 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.

[0109] If the pump 130 operates 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, so the discharged water may escape to the outside of the main housing 100. Also, in a state where the upper housing 110 is not placed on the upper part of the main housing 100, if the light-emitting body of the sterilization unit 161 emits light, the light of the light-emitting body can 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 light-emitting body do not operate.

[0110] For this purpose, a placement sensing unit 170 for sensing whether the upper housing 110 is placed on the upper part of the main housing 100 is provided.

[0111] If the placement sensing unit 170 senses that the upper housing 110 is placed on the upper part of the main housing 100, the power supply is supplied to operate the pump 130 and the light-emitting body. And if the placement sensing unit 170 senses that 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 light-emitting body do not operate. In this case, it can be configured to stop only the power supply to the pump 130 and the light-emitting body, rather than stopping the power supply of the entire pet water supply device 1.

[0112] The placement sensing unit 170 may include a magnet 171 and a magnetic sensor unit 172 for sensing a change in magnetic flux according to the movement of the magnet 171.

[0113] The magnet 171 is coupled to the bottom surface of the upper housing 110, and the magnetic sensor unit 172 is coupled to the main body housing 100. If the upper housing 110 is detached from the main body housing 100, the magnetic sensor unit 172 senses the detachment 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 body housing 100, the magnetic sensor unit 172 senses the magnet 171, and the control unit supplies power to the pump 130 and the light emitter.

[0114] The magnetic sensor unit 172 may be composed of an MR sensor that senses a change in the magnetic field according to the movement of the magnet 171 or a reed switch that is turned on / off according to the movement of the magnet 171.

[0115] 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 can arouse the curiosity of the pet, thereby guiding the pet to the pet water supply device 1 to drink water.

[0116] Refer to Figure 8 , a control method of the pet water supply device 1 will be described.

[0117] As a control mode of the pet water supply device 1, a first mode in which the pump 130 continuously operates so that the water does not stop and continuously circulates, and a second mode in which the pump 130 repeatedly operates for a first set time period and stops for a second set time period can be set.

[0118] By varying the first set time and the second set time variously, the second mode can be implemented as multiple modes.

[0119] If the pump 130 operates, the water inside the water tank 150 flows into the inlet of the pump 130 through the pump inlet filter 133, and the water discharged through the outlet of the pump 130 passes through the water discharge pipe 131, and then is discharged to the upper part of the top plate 120 through the discharge unit 121.

[0120] In this case, a predetermined amount of water is stored in the discharge space 121a of the discharge unit 121, thereby acting as a buffer to prevent the water continuously flowing into the discharge space 121a from splashing into the upper space.

[0121] The water discharged from the discharge unit 121 is prevented from flowing backward by the discharge unit protruding piece 132d and is guided to flow forward to the water storage unit 122.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] In addition, when water flows over the protrusions 124, it presents a wave-like state, thereby arousing curiosity and allowing the pet to drink water.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] The water after filtering foreign matters through the filter parts 141 and 142 is stored in the water tank 150, and then continues to circulate by means of the pump 130.

[0131] Although the preferred embodiments have been described in detail for the present invention as above, the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the claims, the detailed description of the present invention, and the drawings, and they belong to the present invention.
