Summary of the Invention

Problems to be Solved by the Invention

[0004] When giving water using a water bowl or the above-mentioned watering supplies, there is a possibility that the pet's saliva, hair, dust, etc. may mix in and the water may be contaminated. Therefore, there were hygienic problems such as the growth of various bacteria in the water that the pet put its mouth to.

[0005] On the other hand, in the case of a circulating water supply device, although filtration is performed by a filter, water mixed with saliva and the like circulates inside the water supply device, and there is a possibility that various bacteria may grow or a slimy feeling may occur inside the water supply device, and there were also hygienic problems.

[0006] Therefore, pet owners are required to frequently clean water bowls and water dispensers, and to always replace the water with clean water, which they sometimes find troublesome.

[0007] Cats are known to prefer clean environments and have a keen sense of smell. Therefore, they have a natural preference for fresh, clean water and tend to prefer flowing or moving water, such as water directly from a tap, rather than still water stored in a water bowl.

[0008] Therefore, cats may be reluctant to drink water from a water bowl they have already sipped from. As a result, they may not get enough water to meet their daily water intake, making them more susceptible to dehydration, especially during the summer months, and increasing their risk of developing kidney failure. Consequently, it may be difficult to adequately manage the health of pets.

[0009] Therefore, in view of the above circumstances, this invention aims to provide a pet watering device that does not store water in a water bowl or the like, and does not circulate water, thereby enabling a constant supply of fresh water, thereby maintaining the health of pets and reducing the effort required for pet owners to manage hygiene.

Mode for Carrying Out the Invention

[0019] Hereinafter, embodiments of the pet water supply device of the present invention will be described in detail with reference to the drawings. Note that the pet water supply device of the present invention is not particularly limited to the following embodiments, and various design changes, modifications, and improvements can be made without departing from the gist of the present invention.

[0020] Also, in this specification, although mainly assuming "cat" as a pet and making an explanation (see FIG. 3), the present invention is not limited thereto, and other animals such as dogs can also be suitably used. Furthermore, it may also be used for various animals bred in zoos and the like other than pets (companion animals).

[0021] [1. Pet Water Supply Device of the First Embodiment] The first embodiment of the present invention, a pet water supply device 1 (hereinafter simply referred to as "water supply device 1"), mainly comprises a water supply device body 10, a water storage tank 20, a detection sensor 30, a water supply nozzle 40, and a water supply control valve 50, as shown in Figures 1 to 3.

[0022] This allows the water supply control valve 50 to be controlled in conjunction with the detection result of the detection sensor 30 detecting the approach of pet P or the drinking behavior of pet P. When the water supply control valve 50 is opened, the water W from the water storage tank 20 flows down through the water supply channel 12 inside the water supply device body 10 and out of the water inlet 41 of the water supply nozzle 40 according to its own weight. Furthermore, the water W after it has flowed down is not recovered and is discharged as wastewater W1. In other words, it is configured as a non-circulating water supply device 1.

[0023] The water supply device body 10 can be configured as a substantially cylindrical housing, for example, as shown in Figure 1. This shape is not particularly limited, and it may also be a substantially rectangular parallelepiped or a cube, and a shape and design that blends in with the surrounding environment, such as a kitchen, where the water supply device 1 of the first embodiment is installed may be adopted. Furthermore, the material that constitutes the water supply device body 10 is not particularly limited, but it may be made of plastic or metal such as stainless steel.

[0024] The water supply device body 10 has a tank connection part 11 on its upper surface 13 that opens upward so that it can be detachably attached to the water storage tank 20 in an inverted state with the outlet 21 facing downward. The tank connection part 11 may be configured to be compatible with various water storage tanks 20 having different diameters and thread shapes, for example, by interposing a configuration such as multiple connection adapters 16 to standardize the connection to the tank connection part 11 and making it detachable from the water storage tank 20.

[0025] For example, by providing a connection adapter 16 with a female thread structure having a male thread portion 22 formed on the spout 21 corresponding to the mouth of a commercially available plastic bottle and a female thread portion 14 that can be screwed into it, between the tank connection portion 11 and the existing plastic bottle, it may be possible to reuse the plastic bottle as a water storage tank 20.

[0026] Inside the water supply device body 10, there is a water supply channel 12 that communicates with the tank connection section 11. This allows the water W supplied from the water storage tank 20 to be introduced into the water supply device body 10 through the tank connection section 11.

[0027] Furthermore, the other end of the water supply channel 12 is connected to one end 42a of the water supply nozzle 40 near the upper surface 13 of the main body. This water supply channel 12 can be constructed using a pipe-shaped piping or the like that connects the tank connection part 11 and the water supply nozzle 40. As a result, the water W from the water storage tank 20 can flow down from the water inlet 41, which corresponds to the other end 42b of the water supply nozzle, after passing through the tank connection part 11, the water supply channel 12, and one end 42a of the water supply nozzle.

[0028] The water storage tank 20 is not particularly limited as long as it has the function of storing a predetermined amount of water W, and can be detachably attached to the top of the water supply device body 10.

[0029] The material and shape of the water storage tank 20 are not particularly limited, but for example, a plastic container including the aforementioned PET bottle may be used. Commercially available PET bottles have the advantage of being readily available as water storage tanks 20, and by pre-filling multiple PET bottles with water W, the replacement of the water storage tank 20 can be carried out quickly.

[0030] On the other hand, for pet owners who have a strong interest in environmental issues, such as paying attention to the use of environmental hormones (endocrine disruptors) like bisphenol A (BPA), a water storage tank 20 made from materials other than plastic, such as glass, ceramic, and porcelain containers, may be used. This makes it possible to configure a water supply device 1 that takes into account the environmental orientation of pet owners. In particular, by adopting the aforementioned connection adapter 16, it becomes possible to stably install and set the water storage tank 20 on the water supply device body 10 without causing problems such as water leakage, even if the glass container has different specifications such as screw shape.

[0031] When a glass container (glass bottle) is used as the water storage tank 20, the amount of water W stored inside can be easily seen from the outside because the glass container is primarily transparent. Therefore, the owner can easily grasp the situation before the water W in the water storage tank 20 runs out. This prevents a situation where the pet P cannot be supplied with water W when it wants to drink.

[0032] Similar to the water supply device body 10 described above, these water storage tanks 20 may also be selected to match the design and color of the indoor environment, such as the kitchen, where the water supply device 1 of this invention is installed.

[0033] Furthermore, by adjusting the water storage capacity of the water storage tank 20, it is possible to extend the replacement interval of the water storage tank 20, or to accommodate situations where many pets P are being kept, or where pets P are large and drink a large amount of water at a time.

[0034] On the other hand, the detection sensor 30 has the function of detecting when a pet P approaches the water supply device body 10 or the water supply nozzle 40, or when the pet attempts to drink water W. The installation location of the detection sensor 30 is not particularly limited, but for example, as shown in Figures 1 and 3, a part of the detection sensor 30 may be visible from the side of the water supply device body 10.

[0035] Here, the detection sensor 30 is equipped with various components such as a transmitter and a light receiver. Therefore, in addition to the detection sensor 30 being visible from the outside on the side surface 15 of the main body as described above, other components such as the electronic circuit inside the detection sensor 30 and the drive power supply 31 for driving the sensor may be embedded inside the water supply device main body 10. The structure and effects of such a detection sensor 30 are well known, so a detailed explanation is omitted here.

[0036] As a result, when pet P approaches the water supply device body 10 or water supply nozzle 40 of the water supply device 1 to drink water W, the detection sensor 30 can detect this approach. In this case, the effective detection range of the detection sensor 30 can be adjusted arbitrarily. If the effective range is too wide, even when the detection sensor 30 detects pet P and the flow of water W from the water supply nozzle 40 begins, pet P may not have yet reached below the water supply nozzle 40. Therefore, by fine-tuning the effective detection range, the timing of the water W flowing from the water supply nozzle 40 after detecting pet P can be adjusted.

[0037] Herein, the type and detection method of the detection sensor 30 in the water supply device 1 of the present invention are not particularly limited. For example, conventional non-contact sensors such as infrared sensors and ultrasonic sensors can be used. Furthermore, the detection sensor 30 may detect drinking behavior or actions such as the pet P bringing its mouth close to the water outlet 41 by measuring distance changes using an image sensor or ultrasonic sensor. For example, in the case of cats, they may exhibit characteristic behaviors such as digging or scratching around the floor or container with their front paws before drinking water W. In this case, the detection sensor 30 may detect such prior drinking behavior and control the water supply control valve 50.

[0038] To give a more specific explanation of the proximity detection sensor 30, for example, in the case of infrared sensors, there are mainly two types known: a "passive type" that detects far-infrared rays emitted by heat sources such as the human body or pets, and an "active type" that emits infrared rays and detects their reflectivity, etc. Furthermore, the power supply 31 for driving the detection sensor 30 is not particularly limited and is not limited to battery operation using dry cell batteries or rechargeable secondary batteries, but may also be AC ​​powered using, for example, an AC adapter. These power supplies and driving methods are also used as the power supply for the water supply control valve 50, which will be described later.

[0039] When the detection sensor 30 detects that pet P has approached the water supply device 1 (water supply device body 10 or water supply nozzle 40), for example, to a distance of several tens of centimeters, a detection signal is sent inside the water supply device body 10 to the water supply control valve 50 via the valve control unit 32, which controls the opening and closing of the water supply channel 12. Here, the water supply control valve 50 can be configured using a commercially available solenoid valve, and when pet P is not detected by the detection sensor 30, the closed control state, which closes the water supply channel 12, is maintained. This prevents water W from the water storage tank 20 from flowing through the water supply channel 12.

[0040] On the other hand, when the valve control unit 32 receives the detection signal, the water supply control valve 50 is opened. As a result, the water supply channel 12 opens, and the water W from the water storage tank 20 passes through the water supply channel 12 due to its own weight (gravity), reaches the water supply nozzle 40 connected to the water supply channel 12, and then flows down from the water inlet 41 of the water supply nozzle 40. In other words, the water supply device 1 of this invention allows water W to flow down from the water inlet 41 by its own weight without using a driving means such as a pump.

[0041] Here, if the water storage tank 20 is sealed, there is a possibility that the water W inside will not flow down due to its own weight. For this reason, an air intake structure, such as an outside air intake passage (not shown), may be provided to take in outside air into the water storage tank 20 when the water W flows down to the tank connection part 11 or the connection adapter 16. Alternatively, as shown in Figure 1, an air intake hole 23 may be provided at the bottom of the water storage tank 20, that is, at the top of the water storage tank 20 when it is in an inverted state with the outlet 21 facing downwards. In this way, water W may be stored in the water storage tank 20 with a stopper (not shown) fitted over the air intake hole 23, and outside air may be taken into the water storage tank 20 by opening the stopper when in use.

[0042] As a result, stable flow of water W is possible due to its own weight, with virtually no operating noise or vibration from the pump or other motors. Therefore, even animals that are sensitive to sound, such as cats, can approach the water inlet 41 without becoming particularly wary, thus encouraging natural drinking behavior.

[0043] Furthermore, in the water supply device 1 of this embodiment, the water supply control valve 50 may variably control the flow rate of water W from the water supply nozzle 40 according to the detection result of the detection sensor 30. This makes it possible to adjust the amount of water supplied from the water supply nozzle 40 according to the strength of the detection intensity of the detection sensor 30. For example, when the detection sensor 30 detects a pet P near the boundary of the sensor's effective range, it may supply a low flow rate of water W as priming water, and then, when it detects that the head of the pet P is located within the drinking space D (details will be described later), it may switch to a water volume suitable for drinking. In other words, the degree of opening of the water supply control valve 50 by the valve control unit 32 can be changed according to the detection intensity of the detection sensor 30. This makes it possible to reduce the wasteful consumption of water W in the water storage tank 20.

[0044] Here, the shape of the water supply nozzle 40 in the water supply device 1 of this embodiment is not particularly limited. However, for example, as shown in Figure 1, it may be an inverted L-shape that extends upward from the upper surface 13 of the water supply device body 10 and is further bent horizontally.

[0045] Furthermore, as shown in the water supply device 1a of the second embodiment described later (see Figure 4), it may have a roughly inverted U-shape, where it rises upward and then bends so that the water inlet 41 faces downward. In other words, it may have a structure in which at least a part extends upward from the water supply device body 10.

[0046] This allows a drinking space D to be formed between the water inlet 41 located at the tip of the water supply nozzle 40 and the installation surface G (see Figure 3) of the water supply device body 10, for the pet P to drink the water W flowing down. As a result, the pet P can insert its head into the drinking space D and directly drink or lick the water W that flows vertically down from the water inlet 41. Furthermore, in order to cause the water W to flow down by its own weight, the water inlet 41 must be located at least below the water surface of the water storage tank 20 when it is full. For this reason, as shown in Figure 1, the water inlet 41 may be located slightly above the top surface 13 of the water supply device body 10. Furthermore, auxiliary members such as a stand may be provided to hold the water storage tank 20 at a position higher than the water inlet 41.

[0047] As explained above, the water supply device 1 of the first embodiment allows pet P to be provided with "fresh" and "moving" water W flowing down from the water inlet 41, rather than stagnant water accumulated in a water bowl or the like. As a result, pet P will not be reluctant to drink water and will be able to take in the amount of water W required per day.

[0048] Furthermore, any water left over by the pet P (wastewater W1) can be directly discharged into the sink S, for example, as shown in Figure 3. In other words, by installing the water supply device 1 of this embodiment near the sink S, the wastewater W1 left over by the pet P flows down from the water inlet 41 and can be easily disposed of. The water supply nozzle 40 may have a nozzle rotation mechanism that can rotate on an axis on the upper surface 13 of the water supply device body 10. This allows a part of the water supply nozzle 40 (the tip side) to be rotated along the rotation direction R, for example, as shown in Figure 1, and the position of the water inlet 41 relative to the sink S and the flow position of the water W can be finely adjusted.

[0049] According to the water supply device 1 of the first embodiment, the water W that flows down from the water inlet 41 is not recovered again. In other words, the wastewater W1 that the pet P has left undrank is not returned to the water storage tank 20 or the like and reused. That is, since the wastewater W1 flows directly into the sink S, contaminated water W containing saliva, etc., is not re-contaminated with drinking water W, and fresh water W is always supplied from the water inlet 41. As a result, the growth of bacteria and the formation of slime do not occur, and a good hygienic environment can be maintained without requiring much effort for hygiene management.

[0050] [2. Pet water dispenser according to the second embodiment] The water supply device of the present invention may be configured, for example, as a second embodiment of the water supply device 1a shown in Figure 4. The second embodiment of the water supply device 1a includes the same basic structure as the first embodiment of the water supply device 1 described above, and is further configured to include a wastewater collection section 60 below the water inlet 41. In the following description of the second embodiment of the water supply device 1a, components having the same configuration and function as the first embodiment of the water supply device 1 described above will be denoted by the same reference numerals, and detailed descriptions will be omitted.

[0051] As shown in Figure 4, the wastewater recovery unit 60 in the water supply device 1a of the second embodiment mainly comprises a water receiving tray 61 and a wastewater storage unit 62. The wastewater recovery unit 60 has a structure in which the two members, the water receiving tray 61 and the wastewater storage unit 62, are stacked in two stages.

[0052] Here, the water receiving tray 61 has multiple water passages 63 through which wastewater W1 left over by the pet P can pass. On the other hand, the wastewater storage section 62 is located below the water receiving tray 61 and has the function of storing the wastewater W1 that has passed through the water receiving tray 61.

[0053] By adopting this configuration, the wastewater W1 that flows down from the water inlet 41 and is not consumed can be temporarily stored in the wastewater collection unit 60. This allows the water supply device 1a of this invention to be installed not only near the sink S, but also, for example, in the living room. Therefore, the water supply device 1a is not restricted by its installation location and can be installed indoors or outdoors.

[0054] Furthermore, the wastewater W1 that accumulates in the wastewater storage section 62 and is collected cannot be drunk by the pet P because the water receiving tray section 61 acts as a physical barrier covering the top of the wastewater storage section 62. In other words, the wastewater W1 and the pet P are blocked off, and the pet P is unable to drink the wastewater W1.

[0055] To explain in more detail, the water W that flows down from the water inlet 41 is not all drunk by the bottle P; the remaining water falls down and reaches the water receiving tray 61 as wastewater W1. The wastewater W1 received in the water receiving tray 61 is then stored in the wastewater storage section 62 through multiple openings 63.

[0056] At this time, the water receiving tray 61 functions as a physical barrier between the pet P and the wastewater W1, so that the wastewater is collected in the wastewater storage section 62, preventing the pet P from putting its mouth to the potentially unsanitary wastewater W1, which may contain saliva or other contaminants. This reduces the possibility of the pet P accidentally drinking the unsanitary wastewater W1 and encourages it to drink the sanitary, fresh water W flowing down from the water inlet 41.

[0057] The wastewater recovery unit 60 may be formed separately and detachably from the water supply device body 10, or it may be formed integrally with the water supply device body 10. By configuring the wastewater recovery unit 60 to be detachably attached to the water supply device body 10, the wastewater recovery unit 60 can be easily removed from the water supply device body 10, and the wastewater W1 accumulated in the wastewater storage unit 62 can be easily disposed of. Furthermore, cleaning of the water receiving tray 61 and the wastewater storage unit 62 can also be made easier.

[0058] Furthermore, by making the wastewater collection unit 60 detachable from the water supply unit body 10, the water supply unit 1 of the first embodiment (sink-mounted type) installed near the sink S and the water supply unit 1a of the second embodiment (floor-standing type) installed in the living room, etc., can be used interchangeably depending on the installation environment. As a result, it becomes possible to standardize the components other than the wastewater collection unit 60, which reduces manufacturing costs such as design and mold making.

[0059] As described above, the water supply devices 1 and 1a of this invention supply moving water W to the pet, and the water W that has flowed down does not return to the water storage tank 20 or the water supply nozzle 40. Therefore, wastewater W1 does not come into contact with the water supply channel 12 inside the water supply device body 10 or the inside of the nozzle of the water supply nozzle 40. In addition, the detection sensor 30 can be set to close the water supply control valve 50 when the pet P moves out of the effective detection range or when a predetermined time has elapsed since the detection of the pet P. This makes it possible to minimize the consumption of water W.

[0060] In addition, a control unit (control unit) that records and calculates the detection frequency and detection time of the detection sensor 30 may be placed inside the water supply device body 10 of the water supply device 1,1a. Furthermore, by giving the control unit a learning function for the timing of opening and closing the water supply control valve 50, it becomes possible to adjust the water supply time to the optimal time according to the drinking pattern of the pet P. This makes it possible to adjust the water supply time according to the breed of dog or cat, or the size of the dog, such as a large dog. [Industrial applicability]

[0061] The pet watering device of this invention can be suitably used for various animals, especially pets that prefer clean water, such as cats. [Explanation of Symbols]
