Description

Pet litter box

The present invention relates to a pet toilet.

In recent years, with the increase in demand for pets, the opportunities for pets to be kept indoors are increasing. Especially in urban areas, it is becoming mainstream to keep pets indoors rather than outdoors. When keeping pets indoors, the problem is the pet's toilet.

As a pet toilet, a through hole is pierced in the center and an inner lid that is tapered downward toward the through hole is fitted, and the bottom is a fine mesh such as a mesh and a pear net on the upper part of the inner lid. It has been proposed that a toilet bowl body containing toilet sand on the body is fitted to the upper part of a storage container (see, for example, Patent Document 1). According to this pet litter box, urine does not stop on the toilet bowl body, toilet sand, inner lid, etc., and the urine that has flowed down from the through hole of the inner lid is collected in the storage container.

In addition, as a toilet for pets, a urination tray having a toilet sand holding substrate having a large number of small holes as a bottom wall and urine that is placed under the urination tray and falls through the small holes of the toilet sand holding substrate. It consists of a urine collection funnel that collects urine and discharges the collected urine, and a urination storage container that is located under the urine collection funnel and has a mouth that receives liquid from the urine collection tube of the urine collection funnel. Also proposed (see, for example, Patent Document 2). According to this pet toilet, the urine collected by the urination collection funnel is stored in the urination storage container through the urination tube inserted into the mouth of the urination storage container, and the peripheral edge of the urination storage container is urine. It does not get dirty with. In addition, the urination storage container is placed on the urination tray because only the mouth is open and the open surface from which the odor is emitted is extremely small and the upper part is covered by the liquid collection funnel. It is said that bad odors such as ammonia collection can be deodorized by using a toilet sand that has excellent deodorizing properties.

In the present embodiment, an inclined surface 48 having a shape in which the corners of the rectangular parallelepiped are dropped is formed at the meeting portion of the front wall 41 and the right side wall 42 in the tank 4, and the maintenance hole 4c is arranged in the inclined surface 48.

Further, as shown in FIG. 4, the tank 4 has a scattering prevention unit 47 for preventing the liquid in the tank 4 from scattering. The shatterproof portion 47 has a substantially horizontal plate-shaped preventive portion main body 47a that overlaps with the recovery hole 4a in a plan view, and an upper wall 46 that extends upward from the peripheral edge opposite to the maintenance hole 4c in the preventive portion main body 47a in the left-right direction. The maintenance holes 47c of the prevention unit body are formed between the surrounding

walls

47b and 47c that are connected to and surround the upper part of the prevention unit main body 47a from the opposite side to the maintenance holes 47c and both ends in the circumferential direction of the surrounding

walls

47b and 47c. Includes an opening 47d extending upward from the side periphery. In the present embodiment, the surrounding

walls

47b and 47c extend upward from the left end of the prevention portion main body 47a and are connected to the upper wall 46, and the upper wall extends upward from both front and rear ends of the prevention portion main body 47a. It is composed of a pair of front and rear surrounding walls 47c connected to 46. That is, as shown in FIG. 5, each front-rear surrounding wall 47c surrounds the grip portion 4b side (front side) above the prevention portion main body 47a and the side opposite to the grip portion 4b (rear side) in the front-rear direction. Further, as shown in FIG. 7, the tank 4 has a flange portion 47e extending downward from the lower side of the opening 47d at the peripheral edge of the prevention portion main body 47a, and a diaphragm extending downward from the upper wall 46 and having a lower end forming the upper end of the opening 47d. It has a wall 47f and. The flange portion 47d suppresses the infiltration of the liquid scattered in the vicinity of the prevention portion main body 47a into the recovery hole 4a side, and the narrowing wall 47f narrows the opening 47d to suppress the infiltration of the liquid into the recovery hole 4a side. ..

As shown in FIG. 6, the grip portion 4b includes a recess 4b1 formed in a rearward recess in the front wall 41, a front wall 4b2 extending downward from the front end of the upper wall 46, and a return portion extending rearward from the front wall 4b2. It is composed of 4b3 and. In the present embodiment, the recess 4b1 is formed vertically on the front wall 41. Further, the front wall 4b2 is formed at a distance from the recess 4b1 in the front-rear direction.

As shown in FIG. 4, the recovery hole 4a is located on the grip portion 4b side (front side) of the center of the upper wall 46 in the direction orthogonal to the extending direction (front-back direction) of the front wall 41 where the grip portion 4b is provided. It is formed. Further, the recovery hole 4a is formed on the opposite side (left side) of the maintenance hole 4c from the center of the upper wall 46 in the extending direction (left-right direction) of the front wall 41 where the grip portion 4b is provided.

In the present embodiment, the positions of the recovery holes 4a are the gripping posture in which the tank 4 is gripped, the discharging posture in which the liquid in the tank 4 is discharged, and the inside of the tank 4 below the right side wall 42. It is set in consideration of the placement posture in which it is placed in a predetermined place. As shown in FIG. 7, the reference capacity is the capacity at which the liquid in the tank 4 has a water level L1 that coincides with the lower surface of the prevention portion main body 47a. Then, as shown in FIG. 8, when the tank 4 is in a gripping posture in which the front wall 41 provided with the grip portion 4b is upward, the water level L2 of the liquid of the reference capacity in the tank 4 is from the recovery hole 4a. The position of the recovery hole 4a is set so as to be low. Further, when the tank 4 is tilted downward from the gripping posture toward the maintenance hole 4c and the water level L3 of the liquid of the reference capacity reaches the maintenance hole 4c, the reference capacity in the tank 4 is reached. The position of the recovery hole 4a is set so that the water level L3 of the liquid is lower than the recovery hole 4a. Furthermore, when the tank 4 is placed in a predetermined position with the right side wall 42 facing down, the water level L3 of the liquid of the reference capacity in the tank 4 is lower than that of the recovery hole 4a. The position of the recovery hole 4a is set.

Further, as shown in FIG. 7, the tank 4 has a urine treatment liquid 6 that is stored inside and treats urine. In the urine treatment liquid 6, water is used as a solvent, an acid that reacts with ammonia is used as a solute, and a surfactant that kills microorganisms is used. In the present embodiment, tartaric acid is used as the acid of the urine treatment liquid 6, and benzalkonium chloride is used as the surfactant of the urine treatment liquid 6. The capacity of the tank 4 is arbitrary, but for example, the above-mentioned reference capacity can be 5 liters or more and 20 liters or less. By making it possible to store 5 liters or more of liquid in the tank 4, it is possible to handle urine for about one week of a small dog, and by making the capacity of the tank 4 20 liters or less, the tank 4 is made compact. The size of the pet toilet 1 can be reduced.

According to the pet toilet 1 configured as described above, when the pet adds to the scaffolding member 3, the released urine falls below the scaffolding member 3 through each passage hole 31. The urine that has fallen below the scaffolding member 3 is received by the upper surface of the upper wall 46 of the tank 4, is guided to the collection hole 4a along the inclined portion of the upper surface, and flows into the tank 4 from the collection hole 4a. The urine that has flowed into the tank 4 is treated by the urine treatment liquid 6 and stored in the tank 4.

In the present embodiment, the tartaric acid contained in the urine treatment liquid 6 neutralizes the ammonia contained in the urine to form ammonium tartrate. As a result, the ammonia contained in the urine disappears immediately after the urine flows into the tank 4, and the tank 4 is not filled with the offensive odor caused by the ammonia. In addition to this, the benzalkonium chloride contained in the urine treatment liquid 6 kills the microorganisms contained in the urine. As a result, urea contained in urine is not decomposed into ammonia by microorganisms, and the generation of ammonia in the tank 4 can be suppressed. In addition, components other than urea contained in urine are not decomposed by microorganisms. Therefore, even if urine is stored in the tank 4 for a long period of time, urea and other components are not decomposed and an offensive odor is not generated.

Here, the concentrations of tartaric acid and benzalkonium chloride in the urine treatment liquid 6 are consumed and diluted and decreased as urine flows into the tank 4 from the state initially stored in the tank 4. The concentrations of tartaric acid and benzalkonium chloride in the urine treatment liquid 6 are arbitrary, but the effect of treating urine when urine flows into the tank 4 and the liquid in the tank 4 reaches the above-mentioned reference volume. Must be set to be maintained. For example, if tartaric acid can be maintained at 0.05% by weight or more and benzalkonium chloride at 0.05% by weight or more, the effect of treating urine can be maintained. Therefore, it is desirable to determine the amount of the urine treatment liquid 6 initially stored in the tank 4 in consideration of the consumption amount and the degree of dilution of tartaric acid and benzalkonium chloride until the reference volume is reached. For example, the concentrations of tartaric acid and benzalkonium chloride in the initial urine treatment liquid 6 can be set to 2.0% by weight or more and 10.0% by weight or less, respectively. Further, for example, the amount of the initial urine treatment liquid 6 can be 50 cc to 1000 cc. By setting the concentration of benzalkonium chloride to 10.0% by weight or less, it can be made relatively safe for the human body. Further, by setting the concentration of tartaric acid to 10.0% by weight or less, the odor of tartaric acid can be suppressed to a level that is not noticed by humans around the toilet.

In this way, the urine released from the pet is collected in the tank 4 and processed by the urine treatment liquid 6, so that an offensive odor caused by urine is generated unless all the urine treatment liquid 6 in the tank 4 is consumed. There is no such thing. Therefore, it is not necessary to maintain the state in which the toilet sand is spread on the scaffolding member 3 in order to prevent the odor as in the conventional case, and the monitoring burden of the owner's pet toilet 1 can be reduced.
Further, once the tank 4 is replenished with the urine treatment liquid 6, the pet's urine can be treated for a long period of time. Therefore, it is not necessary to replace the toilet sand regularly as in the conventional case, it can be left for a long time, and the owner can be released from stress.
Further, it is not necessary to spread the toilet sand on the scaffold member 3 as in the conventional case, the toilet sand can be omitted, and the height dimension of the pet toilet 1 can be reduced by the amount of the toilet sand, and it is for pets. The size of the toilet 1 can be reduced.

Further, since the urine treatment liquid 6 is a liquid, the surfactant and the acid in the urine treatment liquid 6 can be consumed uniformly and surely. On the other hand, in the configuration in which the solid urine treatment material is put in the tank 4, the urine treatment material in the vicinity of the inflow portion is consumed in advance, and the consumption state of the urine treatment material in the tank 4 becomes uneven and stable. Deodorant performance cannot be exhibited. Further, in the configuration in which the solid urine treatment material is put in the tank 4, if the content of the surfactant and the acid in the urine treatment material is increased so that the urine treatment function is not impaired for a long period of time, the content of the surfactant and the acid is increased immediately after the start of use. Excessive surfactant and acid will dissolve in a small amount of urine. As a result, the concentration of the liquid surfactant and the acid in the tank 4 becomes extremely high, which may adversely affect the human body or the like during the liquid discharge work, which is extremely dangerous. In the pet toilet 1 of the present embodiment, since the surfactant and the acid are consumed as the urine is treated, the concentration of the surfactant and the acid in the urine treatment liquid decreases with time. Therefore, if the concentration of the surfactant and the acid in the urine treatment liquid 6 at the start of use is set as a concentration safe for the human body, the concentration will not be exceeded during use and the liquid in the tank 4 will be discharged. There is no risk of adverse effects on the human body at times.

Further, in the tank 4, since the recess in which the liquid is stored is closed by the upper wall 46, the urine treatment liquid 6 stored in the tank 4 does not scatter to the surroundings. In particular, according to the present embodiment, even if vibration is applied to the tank 4 or the tank 4 is tilted due to the movement of the pet toilet 1 or the like, the shatterproof portion 47 arranged in the tank 4 provides the shatterproof portion 47. The liquid in the tank 4 is prevented from being scattered to the outside of the recovery hole 4a.

Further, the user of the pet toilet 1 can discharge the treated urine through the maintenance hole 4c by removing the lid 49 and opening the maintenance hole 4c. In discharging urine, the operator first opens the front wall 21 as shown in FIG. 2, slides the tank 4 forward using the grip portion 4b, and takes out the tank 4 from the case 2. Then, the tank 4 is gripped by using the grip portion 4b, and the tank 4 is carried to a place where urine can be discharged, such as a toilet in a house. At this time, the posture of the tank 4 changes from the basic posture of the upper wall 46 upward to the gripping posture of the front wall 41 upward, and along with this, the liquid in the tank 4 also mainly changes from the bottom wall 45 side to the rear wall 43 side. Move to. Although the liquid in the tank 4 mainly moves in the front-rear direction and the up-down direction relative to the recovery hole 4a, the prevention portion main body 47a is located directly below the recovery hole 4a, and the front and rear above the prevention portion main body 47a. Is covered by the front and rear surrounding walls 47c, so that it is possible to accurately prevent the liquid from scattering to the recovery hole 4a side. Further, in the gripping posture, the water level L2 of the liquid having the reference capacity in the tank 4 is lower than the recovery hole 4a, so that the urine in the tank 4 does not flow out through the recovery hole 4a when the tank 4 is transported.

Further, in the discharge posture in which the maintenance hole 4c side is tilted downward from the gripping posture and the water level L3 of the liquid of the reference capacity reaches the maintenance hole 4c, the water level L3 of the liquid of the reference capacity in the tank 4 is the recovery hole 4a. Since it is lower than the above, the urine in the tank 4 does not flow out through the collection hole 4a when the urine is discharged. Further, even when the tank 4 is placed in a predetermined position with the right side wall 42 facing downward, the water level L3 of the liquid having the reference capacity in the tank 4 is higher than that of the recovery hole 4a. Since it is low, the urine in the tank 4 does not flow out through the collection hole 4a. As a result, for example, even when the operator places the tank 4 in a predetermined place and temporarily places it before the urine discharge operation, the urine in the tank 4 does not flow out to the outside through the collection hole 4a. Further, even if the urine in the tank 4 infiltrates from the opening 4d onto the prevention portion main body 47a due to vibration or the like when the operator places the tank 4 in a predetermined place, the opening 4d is on the maintenance hole 4c side. Since it is formed, the urine on the prevention portion main body 47a quickly falls into the tank 4 through the opening 4d.

In the above embodiment, tartaric acid is used as the acid that reacts with ammonia in the urine treatment liquid 6, but other acids such as citric acid may be used. Further, although benzalkonium chloride is used as the surfactant for killing the microorganisms in the urine treatment liquid 6, other surfactants such as a quaternary ammonium salt may be used. Further, although the urine treatment liquid 6 is shown to contain both an acid and a surfactant, it may contain either one. Furthermore, as the urine treatment liquid 6, a liquid containing an aromatic component other than an acid and a surfactant can also be used.

Further, the pet toilet 1 of the embodiment may be provided with a notification means for notifying the owner or the like that the liquid in the tank 4 has reached the above-mentioned reference capacity. For example, the notification means is composed of a floater arranged in the tank 4 that moves up and down according to the water level of the liquid, and a pillar that guides the floater up and down and connects the bottom wall 45 and the upper wall 46 of the tank 4. The tank 4 is made of translucent plastic and the upper part of the floater is colored in a color different from that of the tank 4. When the liquid in the tank 4 reaches the water level L1 corresponding to the lower surface of the prevention portion main body 47a, the floater The upper part may be in contact with the upper wall 46. For example, the floater has a main body whose upper portion has a different color from that of the tank 4, and an engaging portion provided on the main body and engaged with a pillar. In this case, the color of the upper part of the floater emerges on the upper wall 46 of the tank 4, so that the owner or the like can know that the liquid in the tank 4 has reached the above-mentioned reference capacity. Here, the installation position of the floater and the pillar is arbitrary, but considering the visibility of the color of the floater from the outside, it is desirable to install the floater and the pillar in the vicinity of the center of the tank 4 in the front-rear direction and the left-right direction. Further, by installing the pillar in the center of the plan view, the rigidity and strength of the tank 4 can be effectively improved.

Further, in the above-described embodiment, the tank 4 is formed in a substantially rectangular parallelepiped shape, but the concave portion capable of storing the liquid and the opening of the concave portion are closed to catch the urine that has passed through the passage hole of the scaffolding member on the upper surface. The shape can be changed as appropriate if it is provided with a plate-shaped closed portion.

As a result, the ammonia contained in the urine disappears immediately after the urine flows into the tank 104, and the tank 104 is not filled with the offensive odor caused by the ammonia. In addition to this, the benzalkonium chloride contained in the urine treatment liquid 6 kills the microorganisms contained in the urine. As a result, urea contained in urine is not decomposed into ammonia by microorganisms, and the generation of ammonia in the tank 104 can be suppressed. In addition, components other than urea contained in urine are not decomposed by microorganisms. Therefore, even if the liquid to be treated is stored in the tank 104 for a long period of time, urea and other components are not decomposed and an offensive odor is not generated.

Further, in the tank 104, since the recess in which the liquid is stored is closed by the upper wall 146, the liquid stored in the tank 104 does not scatter to the surroundings. In particular, according to the present embodiment, even if vibration is applied to the tank 104 or the tank 104 is tilted due to the movement of the pet litter box 101 or the like, the shatterproof portion 147 arranged in the tank 104 The liquid recovery hole 104a in the tank 104 is prevented from scattering to the outside.
