Description

  The present invention relates to a portable toilet for pets, and more particularly to a portable toilet for pets that is portable and can prevent the spread of pet's excrement odor.

When pets such as dogs and cats are kept indoors, it is common to prepare a pet toilet tray in the room and use it on the toilet.
Utility Model Registration No. 3115165 None

  However, even if the toilet is placed on a pet toilet tray, the toilet toilet tray is simply placed in the room, so it is unavoidable that the excrement odor diffuses into the room after the toilet. The room will be filled with the bad odor. It is well known to those skilled in the art that when a pet uses a stool while traveling by a car, the excrement odor fills the narrow car and becomes unbearable.

  On the other hand, since dogs and cats can move the doors (sliding doors) by learning, the present inventor previously proposed a pet animal access device as utility model No. 3115165. This pet animal entry / exit device can be opened easily by the pet itself, and after opening, it automatically closes slowly and naturally, which is of great practical value. As a result of diligent research on whether or not it is possible to prevent the generation of bad odors during pet stool by applying the entrance / exit device, we have succeeded in developing a new portable toilet for pets and propose it here as the present invention. Is.

   A lid that can be opened and closed in a single-opening manner is attached to the opening of the box-shaped main body with an open top, and an air intake duct with a deodorizing filter that incorporates an odor sensor and an electric fan inside the lid. A rectangular opening is provided on the side of the main body, a pair of guide rails are provided in parallel to one direction from the upper and lower portions of the opening, and the opening is opened and closed between the guide rails. A sliding door that is slidable in the left-right direction is provided, and a pulley is pivotally supported above the opening on the side opposite to the moving side of this sliding door, and a cylinder is installed vertically below this pulley. This cylinder has an outer diameter slightly smaller than the inner diameter of this cylinder, and has a small-diameter air passage hole vertically and has a one-way valve that closes the air passage hole when lowered. A ston-like weight is slidably positioned, a wire is stretched between the upper end of the sliding door and the piston-like weight via the pulley, and the sliding door is attached to the side that closes the opening by the weight of the piston-like weight. Furthermore, the above-mentioned problem has been solved by configuring a portable toilet for pets by removing a tray for pet toilets and placing it freely in the main body.

  FIG. 1 is a perspective view of an embodiment of a portable toilet for pets according to the present invention, and FIGS. 2 to 4 are side cross-sectional views of an opening 13 which is a main part of the portable toilet when viewed from the inside of a main body 1. In the figure, reference numeral 1 denotes a portable toilet body, which has a box shape with an opening at the top, is large enough to allow a dog or cat to enter, and is made of plastic or the like. A hinge 2 is attached to one side of the upper opening portion of the main body 1, and a lid 3 is pivotally supported by the hinge 2 in a single-opening manner. The upper opening portion of the main body 1 is connected to the lid 3. Can be opened and closed freely.

  An air intake duct 5 having a built-in electric fan 4 is fixed to the back surface of the lid 3, that is, the main body 1 side, and a deodorizing filter 6 is attached to the air intake side of the air intake duct 5. The deodorizing filter 6 is a combination of a deodorizing agent and a filter, and is in principle the same as that conventionally marketed for toilets and kitchens. In this embodiment, the deodorizing filter 6 is attached to the intake port side of the intake duct 5, but may be attached to the exhaust port side of the intake duct 5, or may be attached to both the intake port side and the exhaust port side. .

  Further, an odor sensor 7 for detecting odor is fixed on the back surface of the lid 3, and the activation of the electric fan 4 can be controlled by the odor sensor 7. In the figure, 24 is a main switch provided between an external power supply (not shown), and 23 is a power supply wire connected to the external power supply. Further, a buckle 8 is provided on the peripheral edge of the upper opening portion of the main body 1 on the side facing the peripheral edge where the hinge 2 is provided, and a locking piece 9 provided at a corresponding position of the lid 3. The lid 3 can be securely fixed to the main body 1 by being engaged with the main body 1.

  On the other hand, a rectangular opening 13 is formed in one of the side surfaces of the main body 1. The opening 13 has a dimension that allows animals such as dogs and cats to use the portable toilet for pets to pass through. As shown in detail in FIGS. 2 to 4, a pair of guide rails 10 and 10 are provided in parallel along the upper and lower edges of the opening 13, and the door pulley 11 is placed on the left and right of the upper and lower edges. The sliding door 12 is positioned so as to be slidable in the left-right direction by engaging the door roller 11 with the guide rail 10. A handle bar 25 is provided on the front and back of the sliding door 12 so that dogs and cats can easily pull the sliding door 12.

  In addition, a pulley 14 is pivotally supported on the outer upper side of the opening 13 on the side opposite to the moving direction of the sliding door 12, and a cylindrical cylinder 15 is positioned directly below the pulley 14. . In this embodiment, the cylinder 15 is made of synthetic resin, but may be made of metal. A cylinder-like piston weight 16 having an outer diameter slightly smaller than the inner diameter of the cylinder 15 is slidably positioned in the cylinder 15, and the piston weight 16 and the sliding door 12 are slidably positioned. A wire 17 is stretched between the upper end via a pulley 14, and in the standby state, the sliding door 12 is positioned closer to the cylinder 15 due to the weight of the piston weight 16, that is, as shown in FIG. At the same time, it is drawn to a position where the opening 13 is closed. The descending speed of the piston weight 16 can be adjusted by appropriately changing the gap between the inner diameter of the cylinder 15 and the outer diameter of the piston weight 16. The piston-shaped weight 16 is provided with a small-diameter air passage hole 18 penetrating the upper and lower sides of the piston-shaped weight 16, and a lower surface of the piston-shaped weight 16 closes the air passage hole 18 only when the piston-shaped weight 16 is lowered. A valve 19 is provided. Further, a window 20 in which a transparent plate 21 is fitted is provided on the side surface opposite to the side surface where the opening 13 is formed.

  A pet toilet tray 22 is detachably mounted on the bottom surface of the main body 1, and pet toilet sand or a pet toilet mat is laid on the pet toilet tray 22. The pet toilet tray 22, pet toilet sand, and pet toilet mat are all the same as commercially available products.

  This embodiment has the configuration as described above. This portable toilet for pets is placed in an appropriate place in a room or in a car, the power supply wire 23 is connected to an external power source, and the main switch 24 is turned on. Keep it. In the standby state, the sliding door 12 covers the opening 13 as shown in FIG. In this state, pets such as dogs and cats have constipation, and when they try to enter the main body 1 and push the sliding door 12 out with their forefoot or head, the sliding door 12 slides as shown in FIG. The opening 13 covered with the sliding door 12 appears until the state shown in FIG. 4 is finally reached, and pets such as dogs and cats enter the main body 1 through the fully opened opening 13. In addition, since the handle bar 25 is formed in the side surface of the side edge of the sliding door 12, a dog, a cat, etc. can slide the sliding door 12 easily by utilizing this. As the sliding door 12 slides, the piston weight 16 is pulled upward as shown in FIGS. 3 and 4. At this time, the air in the cylinder 15 above the piston weight 16 is compressed by the piston weight 16. However, since it moves below the piston weight 16 through the air passage hole 18 and the one-way valve 19, the sliding door 12 can be smoothly slid without resistance. On the other hand, after a dog or cat passes through the opening 13, the piston weight 16 descends in the cylinder 15 due to its own weight, but the one-way valve 19 provided on the lower surface of the piston weight 16 is Since the piston-shaped weight 16 is closed when the piston-shaped weight 16 is lowered, air does not escape from the air passage hole 18, and the air trapped in the cylinder 15 is slightly between the inner wall of the cylinder 15 and the outer peripheral wall of the piston-shaped weight 16. The piston weight 16 slowly descends while being supported by the air pressure, and the sliding door 12 is also moved slowly.

  In this way, after a dog or cat passes through the opening 13, the sliding door 12 returns slowly, the opening 13 is closed, and the inside of the main body 1 is shut off from the outside. In this state, dogs and cats perform stool on the pet toilet tray 22, but the odor emitted from the excrement is detected by the odor sensor 7 fixed to the lid 3. When the fan 4 is activated, the air containing the waste odor in the main body 1 is sucked into the intake duct 5 and deodorized by passing through the deodorizing filter 6, and then circulated in the main body 1. In this embodiment, the electric fan 4 is automatically activated based on the detection of the odor sensor 7, but the electric fan 4 may be manually activated.

  In this way, dogs and cats that have completed stool push out the sliding door 12 and go out of the opening 13 in the same manner as when they entered. After the stool, the owner releases the buckle 8, opens the lid 3 upward, takes out the pet toilet tray 22 from the upper opening, removes excrement, and cleans the pet toilet tray 22. Then, the pet toilet tray 22 is reset in the main body 1 to prepare for the next toilet.

  As described above, in the portable toilet for pets according to the present invention, during and after the stool for dogs and cats, air containing excrement odor is prevented from leaking to the outside and blocked from the outside. In addition, since the internal deodorizing filter and electric fan add deodorizing treatment to the air inside, drastically reduce the excrement odor during the use of pets such as dogs and cats indoors and in cars. It is possible to avoid the trouble of intense excrement odor associated with pet stool, and it is possible to more smoothly carry out symbiosis between humans and pets.
