  The cap body 75, the check valve 76, and the seal member 77 having the above-described configuration are assembled as follows to form the tank cap 72, for example.

  First, as shown in FIG. 2, the helical spring 763 is mounted on the valve rod 762, and the seal member 77 is disposed on the cap body 75. Specifically, the valve rod 762 is inserted from below the helical spring 763, and the lower end of the helical spring 763 is brought into contact with the upper surface of the restriction flange portion 762d. On the other hand, the seal member 77 is inserted into the mounting opening 751 of the cap body 75, and the valve seat boss portion 751 c is inserted into the center hole of the seal member 77 and arranged around the valve seat boss portion 751 c.

  In this state, the valve rod 762 is inserted into the valve support portion 752 of the cap main body 75, and the valve main body 761 is attached to the valve mounting shaft portion 762 b of the valve rod 762. That is, the valve rod 762 is inserted into the inner cylinder portion 752 b of the valve support portion 752 from the lower side of the cap body 75. This insertion is performed until the valve mounting shaft portion 762b of the valve rod 762 is exposed above the inner cylinder portion 752b against the biasing force of the helical spring 763, and the valve mounting shaft portion 762b is located above the inner cylinder portion 752b. The valve main body 761 is mounted on the valve mounting shaft portion 762b in a state where the valve main body 762 is exposed. In mounting, the valve body 761 is inserted in a posture in which the valve body 761 protrudes downward while the mounting umbrella portion 762a of the valve rod 762 is inserted while expanding the mounting insertion hole 761a of the valve body 761, and the valve body 761 is inserted into the valve mounting shaft. It is performed by moving to the part 762b.

  In the tank cap 72 assembled in this manner, the valve main body 761 is in a closed state in which the valve body 761 is pressure-bonded to the valve seat boss 751c by the biasing force of the helical spring 763, and resists the biasing force of the helical spring 763. By moving the valve stem 762 upward, the valve main body 761 shifts to a valve open state separated from the valve seat boss 751c. When the check valve 76 is assembled to the cap body 75, the tip of the contact protrusion 762e of the valve rod 762 and the tip of the protection protrusion 753 are at the same height position or the tip of the protection protrusion 753. Is positioned below to protect the valve stem 762.

  Next, the supply tank 8 will be briefly described. In the present embodiment, the replenishment tank 8 is a plastic bottle as a general-purpose product, and for example, a transparent plastic bottle for storing beverages is used. Although the capacity of the replenishing tank 8 can be changed as appropriate, from the viewpoint of the installation stability of the dog water supply 1, a capacity of about 500 ml can be suitably used. In addition, by using a transparent container as the replenishment tank 8, the water level in the replenishment tank 8 can be visually recognized, and it becomes easy to replenish before the water in the replenishment tank 8 runs out. Can be prevented in advance.

  The dog water dispenser 1 having the above configuration is assembled as follows, for example, and preparations before use are performed.

  First, the circulation pump 5 is attached to the tank body 20. Specifically, the circulation pump 5 is placed between a pair of pump mounting ribs 24a in the bottom wall portion 24 of the tank body 20, and a wiring cord (not shown) of the circulation pump 5 is connected to the tank body 20 through the cord extraction hole 23e. Pull out from the inside.

  Next, the water tank 2 is assembled by attaching the reinforcing guide portion 21 to the tank body 20. Specifically, as shown in FIG. 2, with the hanging piece 212 of the reinforcement guide portion 21 facing inward, the guide attachment hole 23 d provided in the attachment space 2 b of the tank body 20 is inserted into the guide attachment hole 23 d. The guide boss part 213 is inserted, and the top plate 211 of the reinforcing guide part 21 is overlapped with the third step part 23 c of the tank body 20.

  In this state, water is poured into the water storage tank 2 above the reference water level. Specifically, water is filled beyond the vertical height position (reference water level) indicated by the one-dot chain line H in FIG. In the present embodiment, the vertical height position H is set slightly below the first step portion 23a. In addition, it is preferable to inject water above the reference water level in consideration of the fact that the water reaches every corner (for example, inside the circulation pump 5) during driving, and this water injection level is the inner shell of the tank body 20. A sign that can be visually discriminated may be provided on the wall portion 23.

  Then, the filter tray 3 and the filter cartridge 6 are set in the water storage tank 2. Specifically, the filter tray 3 is placed on the first step portion 23 a of the water storage tank 2 and the filter cartridge 6 is stored in the tray body 31 of the filter tray 3. This storage is performed by inserting the cylindrical boss portion 31 a of the filter tray 3 into the center hole (the center hole 613 b and the insertion hole 62 a) of the filter cartridge 6 and placing the filter cartridge 6 on the tray body 31.

  Subsequently, the water intake unit 4 is attached. Specifically, the water supply sleeve 42 of the water supply unit 4 is inserted into the cylindrical boss portion 31 a of the filter tray 3, and then the attachment pipe portion 42 b of the water supply sleeve 42 is tightly connected to the water discharge pipe 51 of the circulation pump 5. It fits outside. Then, the water supply sleeve 42 is pushed in until the positioning step 42 a of the water supply sleeve 42 contacts the top surface of the cylindrical boss 31 a of the filter tray 3, and the water supply unit 4 is attached to the water storage tank 2.

  On the other hand, the stand main body 71 of the tank stand 7 is attached to the water storage tank 2. Specifically, first, the buffer 73 is inserted into the tank holding cylinder 711 of the stand main body 71. Then, the fitting cylinder portion 713 of the stand main body portion 71 is inserted into the guide boss portion 213 through the attachment hole 211 a of the reinforcing guide portion 21. Along with this insertion, the tank engaging piece 712 has its tank engaging protrusion 712d abutted against the outer shell wall portion 22 of the water storage tank 2, and the drooping elastic piece 712b is elastically deformed outward, and the fitting cylinder portion 713 is in the back. In this state, the tank engaging protrusion 712d reaches the locking step portion 22a of the water storage tank 2, and the drooping elastic piece 712b elastically recovers inward. Along with this elastic recovery, the tank engaging protrusion 712d is locked to the locking step 22a, and the stand main body 71 is fixed to the water storage tank 2.

  When removing the stand main body 71 from the water storage tank 2, the lower end of the tank locking piece 712 is gripped, and the tank locking piece 712 is elastically deformed outward, so that the tank engaging ridge 712 d. The stand main body 71 can be easily removed by lifting the stand main body 71 upward while releasing the engagement between the engagement step 22a and the engagement step 22a.

  Next, the tank cap 72 is screwed onto the supply tank 8, and the supply tank 8 is attached to the stand main body 71 together with the tank cap 72.

  Specifically, the female screw portion 751a in the mounting opening 751 of the tank cap 72 is screwed into the male screw portion 8b with the supply opening portion 8a of the supply tank 8 facing upward. This screwing is performed until the seal member 77 is in pressure contact with the tip of the supply opening 8a of the supply tank 8. Thereby, even in the state where the supply opening 8a of the supply tank 8 is directed downward, the leakage of the supply tank 8 can be prevented.

  Subsequently, the supply tank 8 to which the tank cap 72 is attached is attached to the stand main body 71. Specifically, the posture is adjusted so that the gap between the pair of protective protrusions 753 at the front end of the tank cap 72 is directly above the bridging portion 713c of the stand main body 71, and the tank cap 72 is protected and protruded in this state. The stand 753 is sequentially inserted into the stand main body 71. Along with this insertion, the engaging protrusions 711d of the pair of lock pieces 711c in the stand main body 71 abut against the outer peripheral surface of the attachment opening 751 of the cap main body 75, and the pair of lock pieces 711c are elastically deformed outward, respectively. In a state where the mouth portion 751 is in pressure contact with the buffer body 73, the engaging protrusion 711d reaches the upper surface of the attachment mouth portion 751, and each lock piece 711c is elastically recovered inward. Along with this elastic recovery, the engaging projection 711 d is engaged with the upper surface of the mounting opening 751, and the tank cap 72 is locked to the stand main body 71 together with the replenishing tank 8.

  At this time, the upper end of the air slit 715 is opened at the highest position at the lower end opening of the cylindrical sleeve (the fitting cylinder 713 and the discharge cylinder 714) of the tank stand 7. The portion is open between the upper surface position of the foreign matter removal layer 6a of the filter cartridge 6 and the lower surface position of the water quality improvement layer 6b.

  When the tank cap 72 is removed from the stand main body 71, the tilting upper end portion of the lock piece 711c arranged on the outside is gripped, and the lock piece 711c is elastically deformed outward to While releasing the engagement state between the mating projection portion 711d and the upper surface of the attachment port portion 751, the supply tank 8 is tilted slightly outward to change the engagement state between the other engagement projection portion 711d and the upper surface of the attachment port portion 751. It can be easily removed by releasing and lifting the supply tank 8 upward.

  In parallel with the locking operation of the tank cap 72, the protection protrusion 753 reaches the bridging portion 713c as the tank cap 72 is inserted. At this time, when the front end surface of the protective protruding portion 753 hits the bridging portion 713c and further insertion is impossible, the bridging portion is formed in the gap of the protective protruding portion 753 by rotating the replenishment tank 8 around the axis. 713c is fitted, and thus the protective protrusion 753 can be inserted.

  When the protective protrusion 753 reaches the bridge 713c, the contact protrusion 762e of the valve rod 762 abuts on the upper surface of the bridge 713c. In this state, when the replenishment tank 8 is further pushed together with the tank cap 72, the valve rod 762 is pushed against the urging force of the helical spring 763, and the valve body 761 is detached from the valve seat boss 751c with this pushing. Then, the valve is opened.

  The effect | action of the water dispenser 1 for dogs comprised as mentioned above is demonstrated using FIG.

  First, when the circulation pump 5 is driven, the circulation pump 5 takes in the water in the water storage tank 2 and discharges it from the water discharge pipe 51. The discharged water is discharged from the water discharge hole 41 a through the water supply sleeve 42 of the water supply unit 4 and flows down along the upper surface of the water supply main body 41. At this time, the flowing water is once stored in the water storage recess 41 b of the water intake main body 41, overflows from the water storage recess 41 b, reaches the peripheral edge, and flows down to the water receiver 32 of the filter tray 3. The dog ingests water flowing on the upper surface of the water intake main body 41, water stored in the water storage recess 41 b, or water stored in the water receiver 32.

  Then, the water accumulated in the water receiving portion 32 overflows inside, passes through the foreign matter removal layer 6a of the filter cartridge 6, and returns to the water storage tank 2. At this time, in the case where foreign matter such as animal hair, eating straw, and dust is mixed in the circulating water, the foreign matter is removed by the foreign matter removing layer 6a and can be removed from the circulating water. The foreign matter captured by the foreign matter removal layer 6a is not always immersed in water because the upper surface of the foreign matter removal layer 6a is exposed from the water surface in the water storage tank 2, and the foreign matter itself or the surface thereof is not exposed. It can suppress as much as possible that the adhering component melts into the stored water. Moreover, as long as the reference water level is reached, the lower part of the filter cartridge 6, that is, at least a part of the water quality improvement layer 6b is in a state of being immersed in water. The water quality of the stored water can be constantly improved. That is, according to the dog water dispenser 1 of the present embodiment, the water in the water storage tank 2 can be always kept clean, and the water quality can be effectively improved.

  By the way, when the dog ingests water and the water level drops and falls below the reference water level H, the tank stand 7, specifically, the lower end opening of the cylindrical sleeve (the fitting cylinder part 713 and the discharge cylinder part 714) Of the lower end opening 714a and the air slit 715), the upper end of the air slit 715 is exposed from the water surface. With this exposure, air enters from the upper end of the air slit 715, and water is replenished from the replenishment tank 8 to the water storage tank 2 to restore the water level. In addition, when the water level drops vigorously, the air can be rapidly recovered by entering air from the lower end opening 714a of the discharge cylinder 714 in addition to the air slit 715. Thus, when the water level recovers to the reference water level H, the state where the upper surface of the foreign matter removing layer 6a of the filter cartridge 6 is exposed from the water surface is maintained, while the water quality improving layer 6b is always kept immersed in water for a long time. It is possible to maintain the water contamination suppression effect and the characteristic improvement effect of the water in the water storage tank 2 for a long time, and the water given to the pet can be kept clean as long as possible. Can improve the hygiene environment.

  Moreover, since the dog water dispenser 1 of the present embodiment uses a general-purpose plastic bottle as the replenishment tank 8, it can be easily replaced with a new bottle as necessary. The surface can be improved.

  The tank stand 7 includes a stand main body 71 and a tank cap 72 that is detachably attached to the stand main body 71. The tank cap 72 includes a check valve 76, and the stand main body 71. When the valve rod 762 of the check valve 76 is pushed in by the bridging portion 713c and the valve body 761 is released from the valve seat boss portion 751c and is opened, the water in the replenishing tank 8 is reduced. The replenishment tank 8 can be easily removed together with the tank cap 72 by operating the lock piece 711c arranged on the outside, so that water can be supplied easily. Further, due to the action of the check valve 76, water leakage can be effectively suppressed even when the replenishing tank 8 is inverted, and the convenience of handling can be improved.

  The dog water dispenser 1 described above is an embodiment of the pet beverage supply device of the present invention, and the specific configuration and the like can be changed as appropriate without departing from the spirit of the present invention. Hereinafter, the modification is demonstrated.

  (1) In the above embodiment, assuming a dog as the target pet, the water intake unit 4 is also provided with a water storage recess 41b so that water can be temporarily stored. In this case, the specific configuration of the beverage intake unit may be changed in consideration of the properties of the target pet. For example, when a cat is assumed as the target pet, since the cat likes flowing water, the water storage recess may be omitted as a beverage intake unit (water intake unit).

  Specifically, as shown in FIG. 13, a water supply unit 14 according to another embodiment includes a water supply main body 141 configured in an umbrella shape and provided with a water discharge hole 141 a in the center, and the water supply main body 41.

The water supply main body 141 is configured by a smooth curve from the center portion to the outer peripheral edge portion, and unlike the embodiment, the water discharged from the water discharge hole 141a flows continuously without being temporarily stored.

  In this way, by configuring the water intake main body 141 with a smooth curve from the central part to the outer peripheral edge part, it is possible to obtain a flowing water state according to the preference of the cat that is the target pet, and to drink the drink of the pet Can be promoted.

  (2) In the above embodiment, the filter cartridge 6 is obtained by superimposing the supplementary sheet 62 on the storage tray 61. However, the filter portion of the present invention is not limited to this, and the foreign matter removing layer. And it can be widely applied if it has a property improving layer.

  For example, as the filter cartridge 16, as shown in FIG. 14, a supplementary sheet may be further joined to the lower surface of the filter cartridge 6 of the embodiment.

  Specifically, the filter cartridge 16 includes a storage tray 161 for storing a filter medium (not shown), a first supplementary sheet 162 bonded to the upper surface of the storage tray 161, and a first tray bonded to the lower surface of the storage tray 161. 2 supplementary sheets 163. In the filter cartridge 16, a portion corresponding to the first supplementary sheet 162 functions as a foreign matter removal layer 16 a that removes foreign matters contained in water, and a portion corresponding to the storage tray 161 (specifically, the inside of the storage tray 161 The filter medium accommodated in the storage tray 161 functions as the water quality improvement layer 16b for improving the water quality in the water storage tank 2, and the part corresponding to the second supplementary sheet 163 is accommodated in the accommodation tray 161. It functions as the outflow suppression layer 16c that suppresses the outflow of water.
