[0082] As an example, the isolation piece 2 comprises an isolation stand 21 and two isolation side plates 22 respectively extended from two side edges of the isolation stand 21 along the second direction in the third direction; the isolation stand 21 is arranged on a side wall of the cabinet 1 along the first direction, and the arrangement of the isolation stand 21 can divide the internal space of the cabinet 1 into a first cavity and a second cavity; the two isolation side plates 22 are provided with a mounting frame 5 for assembling the fan 4, so that the first cavity serves as a wind generating chamber and the second cavity serves as a wind receiving chamber, and the air in the wind generating chamber is guided into the wind receiving chamber to blow the articles in the wind receiving chamber. The two isolation side plates 22 are in contact with a side wall of the cabinet 1 along the third direction, and there is an air guiding gap between each of the two isolation side plates 22 and two side walls of the cabinet 1 along the second direction, which can increase the channel of the air backflow from the second cavity to the first cavity and improve the backflow rate. The isolation stand 21 is provided with a plurality of first air guiding holes 6 arranged uniformly along the third direction, which facilitates the uniform guidance of the air from the first cavity to the second cavity, ensures the uniform air flow, reduces the wind pressure loss and improves the wind speed. In addition, the isolation stand 21 is perpendicular to a side wall of the cabinet 1 along the first direction, the air is blown from the air outlet of the fan 4 to the bottom of the first cavity, the air is backflowed due to resistance, generates a reverse pressure, forms a pressure chamber, and the air is extruded before passing through the first air guiding hole 6, so that the air is more uniform when it is blown from the first air guiding hole 6, and the wind pressure loss is reduced.

[0083] In an embodiment, referring to Figure 2 and Figure 3 , the isolation stand 21 comprises a straight section 211, a transition section 212 extended from a first end of the straight section 211 along the first direction, and a pressure increasing section 213 extended from a first end of the transition section 212 along the first direction; the width of the straight section 211 is smaller than the width of the transition section 212, the width of the transition section 212 is smaller than the width of the pressure increasing section 213, and the two sides of the pressure increasing section 213 are in contact with two side walls of the cabinet 1 along the second direction; the mounting frame 5 is arranged on the two isolation side plates 22 corresponding to the straight section 211, and the pressure increasing section 213 is provided with a plurality of first air guiding holes 6 arranged uniformly along the third direction.

The two sides of the booster section 213 are connected to the two side walls of the cabinet 1 in the second direction. The mounting frame 5 is arranged on the two isolation side plates 22 corresponding to the straight section 211. The booster section 213 is provided with a plurality of first air guide holes 6 arranged uniformly in the third direction. In this way, the isolation stand 21 is arranged perpendicular to the side wall of the cabinet 1 in the first direction. In the first cavity, the spaces corresponding to the straight section 211, the transition section 212 and the booster section 213 increase in turn, and the pressure chamber can be formed in the space corresponding to the booster section 213. The mounting frame 5 is used to assemble the fan 4. The air outlet of the fan 4 blows the air in the first cavity to flow in the first direction. The air flowing in the first direction is pressed at the pressure chamber, so that the air is extruded before passing through the first air guide hole 6. In combination with the uniform arrangement of the plurality of first air guide holes 6, the air is more uniform when it flows out of the first air guide hole 6, thereby reducing the wind pressure loss.

[0085] In an embodiment, referring to Figure 2 and Figure 5 , the air guide assembly 3 includes an air guide seat 31 and an air outlet plate 32. The air guide seat 31 and the air outlet plate 32 cooperate to form an air guide chamber. The inlet of the air guide chamber is arranged opposite to the first air guide hole 6.

[0086] As an example, the air guide assembly 3 includes an air guide seat 31 and an air outlet plate 32. The air guide seat 31 and the air outlet plate 32 cooperate to form an air guide chamber. The inlet of the air guide chamber is arranged opposite to the first air guide hole 6. The air in the first cavity flows into the air guide chamber from the first air guide hole 6, and then flows into the second cavity through the second air guide hole 7. In this way, the air can be uniformly guided from the air guide chamber to the second cavity. The plurality of second air guide holes 7 are arranged uniformly in the first direction to ensure uniform air flow and reduce wind pressure loss and improve wind speed. At the same time, the noise is reduced, which can meet the use requirements. The air guide seat 31 and the air outlet plate 32 can be connected by bolts and can be independently disassembled. This not only facilitates installation and disassembly, but also facilitates cleaning. The plurality of second air guide holes 7 are arranged alternately, and the air flow is more uniform.

[0088] As an example, the air guide base 31 comprises a bottom plate 311, two first vertical plates 312 and a second vertical plate 313; the bottom plate 311 is mounted on a side wall of the cabinet 1 in the first direction, and the two first vertical plates 312 and the second vertical plate 313 are arranged on the bottom plate 311 in the first direction; the two first vertical plates 312 are oppositely arranged in the second direction; the second vertical plate 313 is oppositely arranged with the first air guide hole 6; the side of the first vertical plate 312 away from the bottom plate 311 is flush with the side of the second vertical plate 313 away from the bottom plate 311 in the vertical direction of the first direction, the side of the first vertical plate 312 close to the bottom plate 311 is an inclined surface, and the height of the part of the first vertical plate 312 away from the first air guide hole 6 in the first direction is less than the height of the part of the first vertical plate 312 close to the first air guide hole 6 in the first direction, so that the air guide bin forms a right trapezoidal air guide bin, the air flowing into the air guide bin is extruded, and the air can flow out of the multiple second air guide holes 7 more uniformly. This arrangement facilitates the uniform flow of air from the air guide bin to the second cavity, ensures uniform air flow, reduces wind pressure loss and improves wind speed, reduces noise while improving wind speed, and meets the use requirements. The right trapezoidal air guide bin is an independent trapezoidal bin body, which is convenient to clean and can form a secondary pressure bin for more uniform upward air outlet; because the right trapezoidal inclined surface is upward and forms an angle with the horizontal plane, the angle becomes smaller and smaller, the air resistance becomes larger and larger, and the upward flow speed becomes faster and faster. Overall, the air volume at each position in the air guide bin is uniform, and the wind speed is also uniform.

For example, the pet is placed in the second cavity, and the air in the first cavity flows into the second cavity to achieve drying the pet by blowing, and the water storage groove formed by the air guide bin can collect water droplets blown off from the pet. The air guide base 31 further comprises a support 315 arranged on the bottom plate 311 in the first direction for supporting the air outlet plate 32, and the air outlet plate 32 cooperates with the air guide bin to form a pressure space, which can cause the air in the pressure space to be extruded, cooperate with the plurality of second air guide holes 7 arranged uniformly, and ensure uniform air flow when guiding the air from the air guide bin into the second cavity, reduce wind pressure loss and improve wind speed, reduce noise while improving wind speed, and meet the use requirements.
