The problem
Traditional pet drying cabinets often have rigid structures that occupy significant floor space even when idle. Additionally, single-source airflow can leave parts of the animal’s coat damp, requiring manual brushing or extended drying times. Ventilation systems in enclosed spaces may also lead to poor air circulation if not designed with adequate intake mechanisms.
The solution
The patent proposes a pet stoving case (drying box) with a modular, collapsible design. The core innovation lies in the side plates, which consist of lower and upper body sections joined by a flexible connection portion. This allows the sides to bend inward, collapsing the unit. Inside, a ventilation system drives heated air through channels located in the back plate, bottom plate, and side plates, creating a multi-directional flow within the first accommodating space. A separate air duct with a second fan introduces fresh external air to ensure proper oxygen exchange.
Who it is for
- Grooming salon owners: Need equipment that maximizes floor space during downtime without compromising drying efficiency.
- Home pet care providers: Benefit from a unit that can be stored in closets or under beds due to its foldable nature.
- OEM manufacturers: Can utilize the existing mold designs for plastic components to produce private-label dryers.
- Veterinary clinics: Require reliable, hygienic drying solutions with features like negative ion generation for sterilization.
How it works
The main parts
| No. | Part | What it does |
|---|---|---|
| 100 | Door Panel | Rotatably and detachably connected between top and bottom. |
| 200 | Back Plate | Contains the first channel for heated air distribution. |
| 300 | Side Plates | Lower/upper sections linked by flexible strips for folding. |
| 400 | Upper Cover | Houses the ventilation device and second air inlet/outlet. |
| 500 | Bottom Plate | Includes second channel and base plate with through-holes. |
| 700 | Ventilation System | Fans, heating members, and ducts circulating air. |
| 910 | Filter Assembly | Prevents hair entry into the air intake. |
Operating steps
- Setup: Unfold the side plates using the flexible connections; lock them in place with buckles.
- Loading: Open the door panel, place the wet pet inside, and close the door.
- Drying: Activate the first fan and heating member. Hot air flows from the back, bottom, and sides simultaneously.
- Ventilation: The second fan draws fresh air from outside through the second air inlet, mixing it with the internal environment to prevent hypoxia.
- Storage: After use, release the locks and fold the side plates inward toward the center.
Applications
Professional Grooming Salons
Salons with limited square footage benefit from the collapsible design, allowing stations to be cleared quickly after appointments. The multi-directional airflow speeds up drying time for large breeds.
Home Use for Small Apartments
Owners living in compact spaces can store the dryer in a closet or under furniture. The fresh air intake ensures the pet remains comfortable during longer drying cycles.
Veterinary Post-Surgery Care
Clinics use these units to dry animals gently after baths. The optional negative ion generator helps sanitize the air, reducing the risk of infection in sensitive post-operative cases.
Mobile Grooming Vans
Space is critical in vans. The ability to fold the unit flat maximizes cargo capacity, making it ideal for mobile groomers who travel between locations.
Where it is less suitable
- Very Large Breeds: The internal volume may be insufficient for giant dog breeds depending on final dimensions.
- High-Humidity Environments: Without advanced dehumidification beyond simple heating, performance may drop in extremely humid climates.

What the claims cover, in plain language
Claim 1 defines a pet drying box comprising a bottom plate, side plates, back plate, upper cover, and door panel. Key feature: the side plates have lower and upper body sections connected by a flexible connection portion, allowing them to bend. A ventilation system includes a fan and heater in a second space (upper cover/back), driving air through channels in the back, bottom, and sides into the main chamber.
Claims 2-5 detail the flexible connection portion as a plastic strip integrally molded with the side plates. They describe how the side plates attach to the bottom and top covers via connecting plates fixed by L-shaped buckles.
Claims 6-11 specify the airflow path. Air moves through cylindrical and curved ducts, then into channels formed in the back plate, bottom plate (with a perforated base plate), and side plates, ensuring multi-directional output.
Claims 12-13 introduce a second air inlet and outlet with a dedicated fan to draw fresh external air into the chamber, preventing oxygen depletion.
Claims 14-18 describe mechanical locking structures, rotating shafts for the door and back plate, and sliding pins for positioning.
Claims 19-21 add optional functional components like negative ion/ozone generators and filter assemblies (plate, screen, ring) at air intakes to block hair.
This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.
What this means for US production
This patent was filed in China and is currently In Force. Making or selling this specific design in China requires the owner’s permission. However, the public record shows no US counterpart. Therefore, manufacturing or selling this design in the United States does not infringe on this specific Chinese patent, provided no similar US patents exist.
Two points to settle early:
- Other patents may exist. Pet grooming appliances are a competitive field. While this specific structural combination appears unique in the public record, broader concepts like heated enclosures or airflow patterns may be covered by existing US utility or design patents. A freedom-to-operate (FTO) review is recommended before mass production.
- Electrical Safety Standards. As a mains-powered appliance with heating elements, strict adherence to UL standards is required for US market entry.

Production notes
Tooling and process
Injection molding is the primary process for the rigid plastic components (plates, covers). The flexible connection portions typically require overmolding with TPE or a separate soft plastic insert. Heat treatment may be applied to metal fasteners for durability.
Cost drivers
Part count is likely high due to the modular design (multiple plates, connectors, fans). Cleaning design impacts cost, as complex channels require thorough flushing to remove mold release agents. Packaging must protect fragile plastic edges during shipping.
Prototyping path
Prototyping typically starts with a 3D-printed sample to verify the folding mechanism and airflow paths. Proceed to a functional sample using off-the-shelf fans and heaters to test thermal clearance. Finally, create short-run molds for bite and pull tests on the flexible hinges.
What we would change before tooling
We would likely verify the thickness of the flexible connection strips to ensure they do not tear after repeated folding. Adjust the filter mesh density to balance airflow resistance with hair capture efficiency. Ensure all electrical components meet IP ratings for moisture resistance.
Common failure points
Bite penetration is unlikely in standard use but material hardness should be checked. Small parts like screws or clips could detach if not properly secured. Dirt trapped in seams around the flexible hinges is a hygiene concern. Edge hardness and wear on the folding joints are critical longevity factors.
