Description

Technical Field

[0001] This utility model belongs to the field of pet supplies and relates to a double-door pet cage with an exhaust system. Background Technology

[0002] Most pet cages on the market are either open cages made of wire mesh and fences, or semi-closed cages made of wood and fences. When the pet door is closed, the odor from the pet's body odor or excrement can easily spread into the building space, which will reduce the air quality of the building, especially for small buildings.

[0003] Meanwhile, most existing pet cages are designed with a single door, resulting in limited space after the door is opened. This makes it inconvenient for pets to enter and exit, as well as for pet owners to clean the cage, access the litter box, and arrange pet supplies. Furthermore, many current pet cages lack effective internal space division, making it difficult for pets to develop good habits within the cage, such as using designated areas for elimination, eating, and resting.

[0004] In addition, most of the existing pet cages with exhaust systems do not have an exhaust pipe structure. Instead, they use activated carbon to filter the gas emitted from the cage before directly releasing it into the house. This method requires frequent replacement of the activated carbon, and due to the limited adsorption effect of the activated carbon, the gas emitted from the cage still has some odor. As for the pet cages that currently use exhaust pipes, their fans are directly embedded in the pipes without fan damping design, resulting in relatively loud noise during exhaust. Furthermore, these pet cage exhaust systems often do not have air filters installed. When foreign objects are sucked into the pipes by the fan, it may cause blockages or damage to the fan. Moreover, if the exhaust fan is damaged, it is inconvenient to replace the fan inside the pipe. Utility Model Content

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0043] like Figure 1 and Figure 2 As shown in the figure, a double-door pet cage with an exhaust system in this embodiment includes a rectangular cage body. The cage body is composed of multiple baffles 1 and angle aluminum 2 connected by corner fittings 3 at each vertex. A partition plate 4 is installed inside the cage to divide the space inside the cage into a resting area and a toilet area. The toilet area is equipped with an exhaust system 5. Ventilation holes 6 are arranged on the lower part of the left, right and back baffles of the cage body. An exhaust pipe 7 connected to the exhaust system 5 is connected to the top baffle on the side of the toilet area. Two rotating doors 8 are provided on the front baffle side of the front of the cage body. When the left and right rotating doors are closed, the entire cage body is almost closed. Most of the air inside the cage can only be discharged to the outside through the exhaust pipe 7. The odor inside the cage will not spread into the room, which can greatly reduce the impact of the pet cage on the indoor air quality of the building.

[0044] like Figures 3 to 5 As shown, the ends of the two wing edges of the angle aluminum 2 are provided with connecting holes 201, and the baffle 1 is provided with limiting holes 101. Each vertex corner piece 3 includes one three-dimensional connector 301, three triangular connecting plates 302 and one three-dimensional corner protector 303. The three-dimensional connector 301 has three adjacent faces, each of which is provided with a connecting plate mounting hole 304 and a baffle positioning post 305. The baffle positioning post 305 is provided with a corner protector mounting hole in the middle. The apex side of the triangular connecting plate 302 is provided with a connecting hole 306 corresponding to the connecting plate mounting hole 304, and the two bottom corner sides are provided with angle aluminum mounting holes 307. The three-dimensional corner protector 303 has three panels, each of which is provided with a fixing mounting hole 308.

[0045] Three triangular connecting plates 302 are fixed to the various surfaces of the three-dimensional connector 301 through connecting plate mounting holes 304, thus forming slots along the X, Y, and Z axes at the intersection of three adjacent surfaces of the three-dimensional connector 301. Angle aluminum 2 is inserted into the slots from three directions, and then bolts are used to connect the angle aluminum mounting holes 307 to the connecting holes 201 on the wing to fix the angle aluminum 2. The limiting hole 101 of the baffle 1 is fitted into the baffle positioning post 305 of the three-dimensional connector 301. Then, the three-dimensional corner protector 303 covers the outside of the three-dimensional connector 301, and the fixing mounting hole 308 is connected to the corner protector mounting hole with bolts to complete the installation of the three-dimensional corner protector. After installation, the baffle 1 is fixed between the three-dimensional connector 301 and the three-dimensional corner protector 303.

[0046] like Figures 6 to 9 As shown, the two revolving doors 8 are designed symmetrically from left to right. A rotating pin 801 is fixed to each revolving door 8, and corresponding pin hooks 802 are provided on the corner aluminum 2 on the left and right sides of the front of the cage, matching the rotating pin 801. To ensure stable opening and closing of the revolving doors 8, an inner-side fixed hinge 81 is used to achieve the rotation function. Specifically, a hinge mounting rod 803 is provided on the fixed side of the revolving door 8. The upper and lower ends of the hinge mounting rod 803 are fixed to the corner aluminum 2 on the upper and lower sides of the cage, respectively. The hinge fixing end 811 is installed on the hinge mounting rod 803, and the baffle 1 on the front is sandwiched between the hinge fixing end 811 and the hinge mounting rod 803. The hinge movable end 812 is installed and connected to the revolving door 8. The hinge mounting rod 803 is made of metal, so the inner hinge 81 and baffle 1 can be stably fixed. At the same time, the hinge mounting rod 803 can also provide some support for the front of the cage. Circular buffer pads 804 are installed at appropriate positions at the top and bottom of the rotating door 8. The buffer pads 804 can reduce the noise when the rotating door 8 is opened and closed, and can also reduce the slight shaking noise caused by the force after the rotating door 8 is closed.

[0047] This pet cage features a double-door design. With both rotating doors 8 open, pet owners can easily access the pet toilet, pet supplies, and allow their pets to enter and exit. Since the rotation center of the rotating door 8 is in the middle of the front, and the sweeping area of ​​the rotating door 8 is in the front of the cage, the opening and closing of the rotating door 8 is not restricted by the space on both sides of the cage. This makes this pet cage more suitable for use in most square building spaces.

[0048] like Figure 10 and Figure 11As shown, the exhaust system 5 includes a fan 501, a fan mounting base 502, and an air filter 503. The air filter 503 is fixed to the fan mounting base 502 by two large-cap hand-tightening bolts 504. The upper and lower sides of the fan 501 are provided with shock-absorbing pads 505. The fan 501 and the two shock-absorbing pads 505 are fixed together inside the fan mounting base 502 by bolts. The bottom of the fan mounting base 502 also has a fan cable outlet groove 506. The upper part of the fan mounting base 502 is provided with a base sealing ring 507, which can further reduce the vibration of the fan 501 during operation. At the same time, the base sealing ring 507 can eliminate the gap between the fan mounting base 502 and the top baffle 1 to ensure the exhaust effect. The upper part of the fan mounting base 502 is equipped with a single-headed nut post 508 that passes through the base sealing ring 507 and protrudes. The single-headed nut post 508 passes through the fan base mounting hole on the baffle 1 at the corresponding position. Then, the base mounting bolt is used to connect it to the single-headed nut post 508, thereby fixing the fan mounting base 502 on the baffle 1. The use of three single-headed nut posts 508 makes it convenient for users to disassemble and replace the fan part of the base.

[0049] like Figure 12 As shown, a control box 10 and a wiring hole 11 are provided on the rear panel at the corresponding position. The control box 10 provides power to the fan and regulates the fan voltage. The power control line of the control box 10 is connected to the fan through the wiring hole 11 and the cable outlet 506.

[0050] like Figure 13 and Figure 14 As shown, the exhaust pipe 7 includes a corrugated exhaust pipe 701, a double-sided protective coil 702, a baffle connecting base 703, and an insect screen 704. The corrugated exhaust pipe 701 has joints at both the top and bottom. The double-sided protective coil 702 is fitted onto the exhaust hole on the top baffle 1. To ensure the fixation effect of the double-sided protective coil 702, a shim ring 705 can be added. The lower connector 706 of the corrugated pipe passes through the double-sided protective coil 702 and is inserted into the fan fixing base 502. The double-sided protective coil 702 is made of soft rubber material, and its main function is to ensure the insertion effect of the lower connector 706 of the corrugated pipe and to eliminate the gap between the lower connector 706 of the corrugated pipe and the exhaust hole of the baffle. The baffle connecting base 703 is fixed on the adjustable baffle 9 of the sliding window. The corrugated pipe upper connector 707 is connected to the baffle connecting base 703. The large outer diameter end of the baffle connecting base 703 is provided with an insect screen 704. Considering that rainwater may enter the exhaust pipe through the insect screen 704 during rainy weather, there is also a rain cover 708 outside the insect screen 704. The rain cover 708 can be fixed on the adjustable baffle 9 of the sliding window.

[0051] like Figure 15 and Figure 16As shown, the partition plate 4 includes a partition base plate 401, which is fixed to the angle aluminum 2 of the cage body using four right-angle connectors 402. The upper edge of the partition base plate 401 has a notch 403, and a doorway 404 is opened in the middle of the partition base plate. A rotatable pet door 406 is installed at the doorway 404 via a non-damped 360-degree hinge 405, facilitating pet access to and from the pet toilet. A detachable fixing plate 408 is installed between the pet door 406 and the partition base plate 401 via hand-tightening bolts 407. When the fixing plate 408 is installed, the pet door 406 blocks the doorway 404; when the fixing plate 408 is removed, the pet door 406 can be rotated inwards and outwards at a large angle. This design is convenient for pet owners to use when training their pets to relieve themselves in a designated spot, and the fixing plate can be removed after training is complete.

[0052] The partition design not only rationally divides the cage space, facilitating the training of good habits for pet owners, but also allows the rotating door on the resting area to remain open when the pet is not caged. After the pet enters the toilet area to relieve itself and leaves, the door automatically closes due to gravity, making the toilet area almost a closed space. This prevents most of the pet's excrement odor from spreading into the building, instead allowing it to be expelled outside through the cage's ventilation system. Furthermore, because the partition has a rectangular notch along its upper edge, even with the exhaust fan running at high speed and both doors closed, air circulation within the cage remains unaffected.

[0053] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly. In this utility model, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal connection of two components or the interaction between two components, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0054] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Although the implementation process of this utility model has been described in detail above, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. All modifications and equivalent substitutions made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
