[0059] Reference Figure 1As shown, an embodiment of the present invention provides a pet drying box, which is a cubic box structure, including a door panel 100 and a back panel 200 arranged oppositely along a first direction X, two side panels 300 arranged oppositely along a second direction Y, and an upper cover 400 and a bottom panel 500 arranged oppositely along a third direction Z (longitudinal direction). The door panel 100, the back panel 200, the two side panels 300, the upper cover 400 and the bottom panel 500 are surrounded to form a first accommodation space 610 for accommodating pets, and the first accommodation space is used to place the pet to be dried. The upper cover 400 and the bottom panel 500 are respectively located at the top and bottom of the first accommodation space 610, and the two are arranged in parallel. The door panel 100, the back panel 200 and the two side panels 300 are respectively located at the periphery of the first accommodation space 610, wherein the door panel 100 and the back panel 200 are arranged in parallel with each other, and the two side panels 300 are arranged in parallel with each other, so that the first accommodation space 610 has a rectangular space structure. The upper cover 400 is provided with a ventilation device 710, the bottom plate 500 is used to carry pets, and the door plate 100 is used to open and close the first accommodation space 610. The two side plates 300, the back plate 200 and the bottom plate 500 are all provided with air outlets for supplying air to the first accommodation space 610 from all directions.

[0060] In order to reduce the size of the pet drying box when not in use for easy carrying and storage, the pet drying box provided in the present application can reduce the size of the first accommodating space 610 by folding, thereby reducing the overall size of the pet drying box.

[0061] The structure of the pet drying box and its corresponding folding method are as follows:

[0062] SIDE PANEL 300:

[0063] Reference Figures 2~4 As shown, the pet drying box provided by the present application includes two foldable side panels 300, and the two foldable side panels 300 are respectively a first side panel 310 and a second side panel 320. The first side panel 310 and the second side panel 320 are arranged opposite to each other and are mirror images of each other. Each side panel 300 includes a bottom connecting plate 311, a lower main body plate 312, an upper main body plate 313 and a top connecting plate 314 that can be bent and connected in sequence. The top connecting plate 314 can be connected to the upper cover 400 through a snap-fit ​​structure or a threaded structure. The bottom connecting plate 311 can be connected to the bottom plate 500 through a snap-fit ​​structure and a threaded structure.

[0064] The first side panel 310 and the second side panel 320 are both of an integrated structure. The connection between any two of the bottom connecting plate 311, the lower main body plate 312, the upper main body plate 313 and the top connecting plate 314 of each side panel 300 is a flexible connecting portion 315. The flexible connecting portion 315 is made of a plastic strip made of a flexible material, and the elastic deformation ability of the plastic material is used to realize the sealable bending connection between the various parts of each side panel 300, which can ensure that the bending requirements are met while not only being more beautiful, but also airtight, and reducing the heat loss of air in the first accommodating space 610. The bottom connecting plate 311, the lower main body plate 312, the upper main body plate 313, the top connecting plate 314 and the flexible connecting portions 315 for sealing connection between each side panel 300 are integrally molded by injection molding through an injection mold using an injection molding process, or are integrally blow molded by blow molding through a blow molding mold using a blow molding process. The above-mentioned one-piece molding can not affect the bending of the side panel 300, and there is no gap at the flexible connection part 315, so as to avoid air leakage during the drying process, reduce heat loss, and improve drying efficiency. The thickness of the flexible connection part 315 is 0.5-2mm to ensure that it has sufficient toughness while having the folding function to avoid the flexible connection part 315 from breaking during the folding process.

[0065] In each side panel 300, the flexible connection portion 315 between the bottom connecting plate 311 and the lower main body plate 312 is located on the side of the side panel 300 close to the first accommodation space 610, so that the lower main body plate 312 can be folded toward the first accommodation space 610. The flexible connection portion 315 between the lower main body plate 312 and the upper main body plate 313 is located on the side of the side panel 300 facing away from the first accommodation space 610, so that the upper main body plate 313 can be folded away from the first accommodation space 610. The flexible connection portion 315 between the upper main body plate 313 and the top connecting plate 314 is located on the side of the side panel 300 close to the first accommodation space 610, so that the upper main body plate 313 can be folded toward the first accommodation space 610. In the folded state, the bottom connecting plate 311 and the top connecting plate 314 are vertically and fixed to the upper cover 400 and the bottom plate 500, respectively. The lower body plate 312 is bent inwardly toward the first accommodation space 610 , and the upper body plate 313 is bent outwardly away from the first accommodation space 610 . In the present application, the folding method of the side plate 300 is that the lower body plate 312 and the upper body plate 313 are folded toward the first accommodation space 610 .

[0066] The lower main body plate 312 is connected to the bottom connecting plate 311 by a flexible connecting portion 315, and one end of the bottom connecting plate 311 is fixed to the side of the bottom plate 500. The bottom connecting plate 311 can not only connect the side plate 300 and the bottom plate 500, but also the space formed between the bottom connecting plates 311 of the first side plate 310 and the second side plate 320 can be used to accommodate the folded back plate 200, making the folding more compact.

[0067] The upper main body plate 313 is connected to the top connecting plate 314 by the flexible connecting part 315, and one end of the top connecting plate 314 is fixed in the groove at the side of the upper cover 400. The top connecting plate 314 can not only connect the side plate 300 and the upper cover 400, but also the space formed between the top connecting plates 314 of the first side plate 310 and the second side plate 320 can accommodate more partial areas of the upper cover 400, so that the upper cover 400 can be designed to be larger in volume without affecting the folding, so as to facilitate the placement of the ventilation system 700.

[0068] Reference Fig.13 As shown, a plurality of L-shaped buckles 350 are fixed to the sides of the bottom connecting plate 311 and the top connecting plate 314, respectively, and the L-shaped buckles 350 are buckled with corresponding shaped holes on the bottom plate 500 and the upper cover 400. The L-shaped buckles 350 can conveniently and quickly assemble the side plate 300 to the bottom plate 500 and the top plate.

[0069] The locking structure 330 of the side panel 300:

[0070] Reference Figure 8 As shown, in order to keep the side plate 300 fixed and in a straight plate shape when in use, a mounting groove 331 is provided at the connection between the lower main body plate 312 and the upper main body plate 313 in each side plate 300. A locking structure 330 is arranged in the groove. The locking structure 330 includes a locking buckle 332 fixed on the lower main body plate 312, and a limiting portion 333 fixed on the upper main body plate 313, and the limiting portion 333 matches the locking buckle 332. The locking buckle 332 can be fitted on the limiting portion 333 by flipping. When the locking buckle 332 is connected to the limiting portion 333, the lower main body plate 312 and the upper main body plate 313 cannot be folded; when the locking buckle 332 is not connected to the limiting portion 333, the lower main body plate 312 and the upper main body plate 313 can be folded toward the first accommodating space 610 through the flexible connecting portion 315 between the two. The upper main body plate 313 and the lower main body plate 312 can be fixed by the cooperation between the lock buckle 332 and the limiting portion 333 .

[0071] Door panel 100 structure and folding method:

[0072] Reference Figure 1 and attached Figure 5As shown, the door panel 100 is rotatably connected to the upper cover 400 and the bottom plate 500, and the door panel 100 can also be removed from the upper cover 400 and the bottom plate 500. A first rotating shaft 110 is provided at the top of the door panel 100 near the first side plate 310, and a second rotating shaft (not shown in the figure) is provided at the bottom of the door panel 100 near the first side plate 310. The axes of the first rotating shaft 110 and the second rotating shaft coincide and extend longitudinally respectively. A first connecting hole for rotatably connecting with the first rotating shaft 110 is provided at the bottom of the upper cover 400 corresponding to the position of the first rotating shaft 110, and a first connecting hole for rotatably connecting with the second rotating shaft is provided at the top of the bottom plate 500 corresponding to the position of the second rotating shaft. The door panel 100 is rotatably connected to the upper cover 400 and the bottom plate 500 respectively through the first rotating shaft 110 and the second rotating shaft, so that the door panel 100 can be reciprocated around the first rotating shaft 110 and the second rotating shaft relative to the first accommodating space 610 to open or close the first accommodating space 610.

[0073] In order to realize the detachable connection between the door panel 100 and the upper cover 400 and the bottom plate 500, an escape groove 130 is provided at the connection between the upper cover 400 and the door panel 100. The outer dimensions of the escape groove 130 match the thickness dimension of the door panel 100. When the door panel 100 rotates around the first rotating shaft 110 and the second rotating shaft to the angle corresponding to the escape groove 130, the door panel 100 can be lifted upward to make the first rotating shaft 110 of the door panel 100 enter the escape groove 130. At this time, the second rotating shaft can be disengaged from the first connecting hole of the bottom plate 500, and then the first rotating shaft 110 of the door panel 100 is disengaged from the escape groove 130, so that the first rotating shaft 110 can be disengaged from the upper cover 400 and the bottom plate 500, and finally the door panel 100 can be disassembled. In addition, in addition to using the avoidance groove 130 structure, other structures or devices that can separate the first rotating shaft 110 and the second rotating shaft from their corresponding first connecting holes can be used, such as using a spring telescopic structure to elastically extend the length of the first rotating shaft 110 and the second rotating shaft. When the door panel 100 needs to be separated from the upper cover 400 and the bottom plate 500, it is only necessary to adjust and shorten the length of the first rotating shaft 110 and the second rotating shaft. A door lock is provided on the side of the second side plate 320 close to the door panel 100. The door lock is a mechanical snap door lock or an electromagnetic door lock, which is used to limit the rotation of the door panel 100 so that the door panel 100 can close the first accommodating space 610.

[0074] In the present application, the door panel 100 is folded in such a way that it is separated from the bottom plate 500 and the upper cover 400 and stored separately.

[0075] Reference Figure 2As shown, the door panel 100 and the two side panels 300 may be provided with observation windows 340, respectively, for observing the drying status of the pet in the first accommodating space 610. The observation windows 340 provided on the two side panels 300 can be opened or closed manually, so that the user can put his hand into the first accommodating space 610 through the observation windows 340 on the two side panels 300 to assist in drying the pet or soothe the pet's emotions during the drying process of the pet.

[0076] Back panel 200 structure and folding method:

[0077] Reference Figure 6 , 7 As shown in Figures 13, the back panel 200 near one end of the upper cover 400 or near one end of the bottom panel 500 can be rotatably connected to the two side panels 300, specifically, the back panel 200 can be rotatably connected to the bottom connecting plate 311 or the top connecting plate 314 of the two side panels 300. Taking the back panel 200 rotatable on the bottom connecting plate 311 as an example, the positions near the bottom connecting plate 311 on both sides of the back panel 200 are respectively provided with a third rotating shaft 210 and a fourth rotating shaft (not shown in the figure), and the axes of the third rotating shaft 210 and the fourth rotating shaft coincide. A second connecting hole 230 that can be rotatably connected to the third rotating shaft 210 is provided on the bottom connecting plate 311 of the first side panel 310 at a position corresponding to the third rotating shaft 210, and a second connecting hole 230 that can be rotatably connected to the fourth rotating shaft is provided on the bottom connecting plate 311 of the second side panel 320 at a position corresponding to the fourth rotating shaft. The back panel 200 is rotatably connected to the first side panel 310 and the second side panel 320 through the third rotating shaft 210 and the fourth rotating shaft respectively so that the back panel 200 can be folded toward or away from the first accommodating space 610. When folding is required, the back panel 200 rotates into the first accommodating space 610 and fits into the bottom panel 500. The height dimension of the bottom connecting plate 311 in the third direction Z is not less than the sum of the thicknesses of the back panel 200 and the bottom panel 500, so that after the back panel 200 is turned over, the back panel 200 as a whole can be placed in the space formed by the bottom connecting plate 311 of the first side panel 310 and the second side panel 320. When the height of the back panel 200 in the third direction does not exceed the height of the bottom connecting plate 311, when the first side panel 310 and the second side panel 320 are folded, the lower main body panels 312 of the two can fit exactly on the back panel 200, so that the back panel 200 can just bear the weight of the side panel 300 and the cover plate on the side panel 300 after folding, thereby avoiding the various flexible connection parts 315 of the side panel 300 from being excessively stressed and pulled apart.

[0089] On the basis of Example 1, in order to cooperate with the folding structure of the pet drying box, this embodiment provides a ventilation system 700 used in the pet drying box. The ventilation system 700 includes a ventilation device 710 and a ventilation channel 720. The ventilation device 710 is located in the second accommodation space 620, and the second accommodation space 620 is connected to the first accommodation space 610 through the ventilation channel 720. The ventilation device 710 is used to heat and drive the gas in the first accommodation space 610 and the second accommodation space 620 to circulate.

[0090] Ventilation device 710 structure:

[0091] Reference Figures 6 to 12 As shown, the ventilation device 710 includes a first fan 711, a wind guide blade 712, a first air duct 713 and a heating component 730 arranged in the second accommodation space 620. The second accommodation space 620 is arranged in the upper cover 400. The upper cover 400 is formed by the first shell 410 and the second shell 420 covering each other from top to bottom. A first air inlet 421 is provided at the middle area of ​​the bottom of the second shell 420, so that the gas in the first accommodation space 610 is sucked into the second accommodation space 620 through the first air inlet 421. A first air outlet 422 is provided at the bottom edge of the second shell 420, and the gas entering the second accommodation space 620 flows out from the first air outlet 422 after being heated. The air inlet and the air outlet of the first air duct 713 are respectively connected to the first air inlet 421 and the first air outlet 422.

[0092] The first fan 711 and the guide blades are arranged in the first air duct 713 and located at the first air inlet 421. The guide blades rotate under electric drive, which can play a dynamic guiding role on the airflow in the second accommodation space 620, and drive the airflow entering the second accommodation space 620 through the first air inlet 421 to flow inside the first air duct 713. The first air duct 713 includes a cylindrical pipe 7131 and a curved pipe 7132. The first fan 711 is arranged in the cylindrical pipe 7131. The air inlet of the first air duct 713 is connected with the second air inlet, so that the gas in the first accommodation space 610 enters the cylindrical pipe 7131 through the second air inlet and the air inlet in turn. The cylindrical pipe 7131 and the curved pipe 7132 are connected to each other, and the air entering the cylindrical pipe 7131 is driven by the guide blades to enter the curved pipe 7132. The curved duct 7132 is arranged around the cylindrical duct 7131, and at least part of the curved duct 7132 is a straight tube duct 7133, and the straight tube duct 7133 is located on the side of the cylindrical duct 7131 close to the first air outlet 422. The air outlet of the first air duct 713 is connected to the first air outlet 422. The cylindrical duct 7131 and the curved duct 7132 can make the air spiral in the first air duct 713, reducing the loss of air kinetic energy.

[0093] The heating component 730 is fixed in the straight tube 7133 at the first air outlet 422 to heat the air passing through the first air duct 713 .

[0094] The upper cover 400 and the first air duct 713 therein can be injection-molded structural parts, blow-molded structural parts or sheet metal structural parts. More preferably, the first air duct 713 can be blow-molded in an integrated manner through a corresponding blow-molding mold using a blow-molding process.

[0095] Ventilation channel 720 structure:

[0096] The ventilation passage 720 includes a first passage 721 , a second passage 722 , a third passage 723 , and a fourth passage.

[0097] Reference Figures 6-8As shown, the first channel 721 is arranged inside the back plate 200. The first channel 721 extends along the third direction Z. When the pet drying box is in use, the first channel 721 is connected to the first air outlet 422. There can be multiple first channels 721, and the first vent 7211 opened on the side of each first channel 721 close to the first accommodating space 610 serves as the air outlet of the first channel 721. Through the first vent 7211, air can be blown to the pet in the first accommodating space 610 from a direction perpendicular to the back plate 200. When the pet drying box needs to be used, the back plate 200 is assembled to the upper cover 400 so that the first air outlet 422 is aligned with the entrance of the first channel 721. After the hot air output from the first air outlet 422 enters the first channel 721, the hot air is transported to the first accommodating space 610 from the second opening in the lower middle part of the back plate 200.

[0098] Reference Figure 6 , 8 As shown in Figures 14 and 15, in order to achieve a better drying effect for the pet, a second channel 722 is provided on the bottom plate 500 of the drying box. The second channel 722 is a groove-shaped structure. The notch end of the groove-shaped structure is connected to the first accommodating space 610. The ends of the first channel 721 in the extending direction are respectively connected to the notch of the groove-shaped structure, so that the hot air in the first channel 721 can flow into the second channel 722 through the notch of the second channel 722. The notch faces the first accommodating space 610 and serves as a second vent 7221, which can blow air to the pet in the first accommodating space 610 from a direction perpendicular to the bottom plate 500. A pad 510 can be inserted on the bottom plate 500 (specifically at the notch of the groove-shaped structure), and the pad 510 is placed on the second ventilation channel 720. The pad 510 used to separate the groove-shaped structure from the first accommodating space 610 is evenly provided with a plurality of through holes 511 or through grooves along the longitudinal direction, so that the groove-shaped structure can be connected to the first accommodating space 610 through the plurality of through holes 511 or through grooves. The plurality of through holes 511 can make the hot air in the second channel 722 evenly distributed when it is blown into the first accommodating space 610. Other functions of the pad 510 include separating the second channel 722 from the first accommodating space 610 and supporting the pet. The hot air in the second channel 722 can pass through the plurality of through holes 511 of the pad 510 to provide hot air to the first accommodating space 610 from bottom to top.

[0099] Reference Fig.13As shown, in order to further improve the pet drying effect, a third channel 723 and a fourth channel (the structure is the same as the third channel 723, not shown in the figure) are respectively provided on the two side panels 300. Among them, the third channel 723 is a groove-shaped structure. The third channel 723 is opened inside the first side panel 310. A plurality of third vents 7231 opened on the side of the third channel 723 close to the first accommodating space 610 serve as the air outlet of the third channel 723. The fourth channel is opened inside the second side panel 320, and a plurality of fourth vents (the structure is the same as the third vent 7231, not shown in the figure) opened on the side of the fourth channel close to the first accommodating space 610 serve as the air outlet of the fourth channel. The openings on both sides of the back panel 200 are respectively connected to the third channel 723 and the fourth channel, so that hot air is injected into the third channel 723 and the fourth channel at the same time. More preferably, the third channel 723 and the fourth channel are respectively arranged on the lower main body plate 312 of the first side plate 310 and the second side plate 320, so as to provide hot air to the first accommodating space 610 from both sides of the side plate 300 without hindering folding.

[0100] The first channel 721, the second channel 722, the third channel 723 and the fourth channel may be a hole-like structure, a tubular structure, a groove-like structure or a cavity structure.

[0101] The ventilation device 710 and ventilation channel 720 provided in the present application are driven by the first fan 711 when working, and the air is heated in the first air channel 713, and first flows into the first channel 721 of the back plate 200. Then, it flows into the second channel 722 connected to the bottom and the third channel 723 and the fourth channel connected on both sides through the first channel 721. Finally, the pet in the first accommodating space 610 is supplied with air from the openings opened in the first channel 721, the second channel 722, the third channel 723 and the fourth channel that are connected to the first accommodating space 610. This drying air supply can supply air to the pet from multiple directions and fully cover, and the drying effect is better. The hot air sent into the first accommodating space 610 finally returns to the first air channel 713 through the first air inlet 421, so that the hot air in the pet drying box can form a thermal cycle, reduce heat loss, and dry faster. Example 3

[0102] Reference Fig.10 and 11As shown, the ventilation system 700 also includes a second air inlet 431 on the side wall of the upper cover 400. A first notch is provided on one side of the first shell 410, and a second notch is provided on the corresponding side of the second shell 420. After the first shell 410 and the second shell 420 are covered by a matching snap-on structure and / or a threaded manner, the first notch and the second notch are combined to form the second air inlet 431. A second air outlet 432 is provided at the bottom of the second shell 420. The second air outlet 432 and the second air inlet 431 are connected to form a second air duct 433, which exists independently of the first air duct 713. A second fan 434 is fixed at the second air outlet 432. The second fan 434 is used to extract air outside the pet drying box from the second air inlet 431 and inject it into the first accommodating space 610 through the second air outlet 432 to prevent the pet from hypoxia.

[0103] The first housing 410 is provided with a plurality of guide grooves 411. The plurality of guide grooves 411 form a second air duct 433 in the second accommodation space 620, and each guide groove 411 can guide the airflow entering the second air inlet 431 from the outside, so that the air flows more smoothly and evenly in the second air duct 433. Example 4

[0104] Reference Fig.10 and 11 As shown, the ventilation device 710 also includes a functional component 740, which includes a negative ion generating device and an ozone generating device. The functional component 740 is built into the first air duct 713, specifically between the straight part of the cylindrical pipe 7131 and the curved pipe 7132. The functional component 740 can form a negative ion and ozone environment, thereby sterilizing the air in the first accommodating space 610 to avoid pet bacteria infection.

[0105] When the ventilation device 710 is in use, external air flow can enter the first accommodating space 610 through the second air inlet 431, and flow in the first accommodating space 610 through the multiple guide grooves 411 opened on the first shell 410, and finally be sent into the drying cavity connected to the second side of the ventilation device 710 through the second air outlet 432 by the second fan 434. When the air flow is sent out from the second air outlet 432, the functional component 740 arranged in the second air duct can also provide a negative ion and ozone environment, thereby sterilizing the air flow in the first accommodating space 610. Example 5

[0106] Reference Fig. 9As shown, a first filter assembly 910 is provided at the first air inlet 421, a second filter assembly (not shown in the figure) is provided at the second air inlet 431, and a third filter assembly (not shown in the figure) is provided at the second air outlet 432. The first filter assembly 910, the second filter assembly and the third filter assembly can filter the airflow respectively, so as to prevent the hair of the pet from entering the first accommodating space 610 or the second accommodating space 620 during the drying process, thereby avoiding clogging of the fan. The first filter assembly 910 is longitudinally mounted with a filter plate 911, a filter net 912 and a fixing ring 913 in sequence. The filter plate 911 and the filter net 912 are installed at the air inlet through the fixing ring 913 to cover the air inlet, so as to filter the airflow passing through the air inlet.
