Detailed Implementation

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] The filter installation structure of this utility model's pet drying box, such as... Figures 1 to 3As shown, the device includes a housing assembly 1, which has a pet housing cavity 10 inside. The front side of the housing assembly 1 has a housing opening 11 for the pet to enter and exit, which is connected to the pet housing cavity 10. The housing assembly 1 is hinged to a housing door 12, which is used to open and close the housing opening 11.

[0020] like Figures 1 to 3 As shown, the top of the pet-containing cavity 10 is equipped with a filter assembly 2, such as... Figure 5 As shown, the filter assembly 2 includes a support frame 21, a front air filter 22, and a rear air filter 23. The front air filter 22 and the rear air filter 23 are placed on the support frame 21. The rear end of the support frame 21 is hinged to the housing assembly 1, as shown. Figure 1 and Figure 3 As shown, in use, the support frame 21 is in a horizontal state, meaning that the support frame 21 supports the weight of the front air filter 22 and the rear air filter 23 to prevent them from falling off. Figure 4 As shown, the support frame 21 can swing downwards, that is, the support frame 21 can swing about the hinge axis between the support frame 21 and the housing assembly 1.

[0021] When it is necessary to clean the front air filter 22 and the rear air filter 23, such as Figure 4 As shown, the support frame 21 is swung downwards to open. Since the rear end of the support frame 21 is hinged to the housing assembly 1, after the support frame 21 is swung downwards and opened, the front air filter 22 and the rear air filter 23 face the housing opening 11. The user can then easily reach their hand through the housing opening 11 into the pet housing cavity 10 and use their hand to remove the front air filter 22 and the rear air filter 23 forward from the support frame 21. Since the front air filter 22 and the rear air filter 23 are placed on the support frame 21, removing them is relatively convenient and quick. The front air filter 22 and the rear air filter 23 can pass through the housing... The filter element 22 can be removed from the pet drying box and rinsed; alternatively, the tray 21 can be swung downwards to open (equivalent to disassembling the filter assembly 2 from its working position), leaving the front air filter 22 and rear air filter 23 on the tray 21, exposing them to the user's view. Then, the front air filter 22 and rear air filter 23 can be rinsed directly inside the pet drying box. That is, the top of the front air filter 22 and the top of the rear air filter 23 can be cleaned without removing them. Since the tray 21 can be swung downwards, cleaning the tray 21 is also relatively convenient. After cleaning, the front air filter 22 and rear air filter 23 are placed back on the tray 21, and then the tray 21 is swung upwards to return it to its horizontal working position. As can be seen from the above, the filter installation structure of this utility model facilitates the easy disassembly and cleaning of the filter assembly 2.

[0022] Furthermore, such as Figure 2 and Figure 6 As shown, the front end of the support frame 21 is provided with a latch 25, which connects the front end of the support frame 21 to the housing assembly 1. The latch 25 is a commercially available product; for example, refer to the patent publication number CN2278063Y for "Latch". The support frame 21 is equivalent to a swing-mounted door leaf. The latch 25 is provided with a sliding bolt 251. By hooking the housing assembly 1 with the bolt 251, the front of the support frame 21 can be prevented from falling due to gravity, thus keeping the filter assembly 2 in a horizontal closed working state. When the bolt 251 is disconnected from the housing assembly 1, the filter assembly 2 can swing downwards by gravity to open, switching to the open maintenance state. By manually swinging the filter assembly 2 upwards to a horizontal position and then moving the bolt 251, the bolt 251 is reconnected to the housing assembly 1. Thus, by providing the latch 25, the filter assembly 2 can be easily switched between the closed working state and the open maintenance state, and the cost of the latch 25 is low.

[0023] Furthermore, such as Figure 3 and Figure 4 As shown, the enclosure assembly 1 includes an air duct cover 3, which is located on the upper side of the pet housing cavity 10. The air duct cover 3 is the internal structure of the enclosure assembly 1, and the front impeller 4 and the rear impeller 5 are rotatably disposed within the air duct cover 3. Figure 4 As shown, a cover opening 31 is formed at the lower end of the air duct cover 3, and a locking hole 311 is formed at the cover opening 31, as... Figures 1 to 4 As shown, when the filter assembly 2 is in the horizontally closed working state, the support frame 21 is located inside the cover opening 31, as... Figure 2 As shown, the bolt 25 includes a bolt rod 251 and a bolt seat 252. The bolt seat 252 is installed on the bracket 21 by fasteners. The bolt rod 251 is slidably connected to the bolt seat 252. The bolt rod 251 passes through the bracket 21, and one end of the bolt rod 251 is inserted into the corresponding lock hole 311. The rear end of the bracket 21 is hinged to the cover 31. Specifically, the rear end of the bracket 21 is provided with a hinge pin 26, which passes through the wall of the cover 31. The structure of the bolt rod 251 inserted into the lock hole 311 is simple and has a low manufacturing cost. When the bolt rod 251 is slidably inserted into the lock hole 311, the bolt rod 251 can quickly form a hook connection with the box assembly 1. The lock hole 311 prevents the bracket 21 from swinging downward.

[0024] Furthermore, such as Figure 5 As shown, the inner side of the support frame 21 is provided with an inwardly protruding support edge 211. The inwardly protruding support edge 211 can be a welded support frame 21, such as... Figure 4 and Figure 5 As shown, the front air filter 22 and the rear air filter 23 are recessed into the bracket 21. For example, as... Figure 5 As shown, the front air intake filter 22 includes a front filter frame 221, and the rear air intake filter 23 includes a rear filter frame 231. When the front air intake filter 22 and the rear air intake filter 23 are placed inside the support frame 21, the top of the front filter frame 221 and the top of the rear filter frame 231 are flush with the top of the support frame 21. Figure 4 and Figure 5 As shown, the edges of the front air filter 22 and the rear air filter 23 are respectively attached to the corresponding convex support edges 211. In other words, the convex support edges 211 actually support the front filter frame 221 and the rear filter frame 231. Since the front air filter 22 and the rear air filter 23 are embedded in the support frame 21, the support frame 21 can position the front air filter 22 and the rear air filter 23.

[0025] like Figure 4 As shown, the duct cover 3 is provided with a front air inlet 301, a rear air inlet 302, and a front air outlet 303. The front air inlet 301, the rear air inlet 302, and the front air outlet 303 are located within the area of ​​the cover opening 31, as shown. Figure 3 As shown, the front air filter 22 is located on the corresponding lower side of the front air inlet 301, and the rear air filter 23 is located on the corresponding lower side of the rear air inlet 302, as... Figure 2 and Figure 6 As shown, the filter assembly 2 also has an air outlet 24, which is located between the front air filter 22 and the rear air inlet filter 23. A grille 241 is provided inside the air outlet 24, as shown... Figure 5 As shown, the left and right ends of the fence rod 241 are inserted into the bracket 21, as follows: Figure 3 As shown, the air outlet 24 is located on the lower side of the front air outlet 303, and both the front impeller 4 and the rear impeller 5 are cross-flow impellers. Figure 3 The dotted arrows in the diagram illustrate the airflow direction generated by the operation of the front impeller 4 and the rear impeller 5. Therefore, the airflow entering the duct cover 3 is filtered by the front air filter 22 and the rear air filter 23, respectively, which significantly reduces the accumulation of pet hair on the inner wall of the duct cover 3, the front impeller 4, and the rear impeller 5. Figure 5 As shown, the end of the convex support edge 211 is bent upward to form a baffle 2111, as... Figure 4 Combination Figure 5 The baffles 2111 respectively prevent the front air filter 22 and the rear air filter 23 from moving towards the air outlet 24. After the filter assembly 2 is swung downwards to open, the front impeller 4 and the rear impeller 5 can be cleaned through the cover 31.

[0026] Furthermore, such as Figure 6 As shown, the bolt 251 is located on the lower side of the corresponding inner convex support edge 211, and the bolt 251 is slidably positioned left and right, as shown. Figure 2As shown, latches 25 are provided at both ends of the support frame 21, so that both ends of the support frame 21 can be supported. When it is necessary to swing the support frame 21 downward to open, the user can reach into the pet holding cavity 10 through the box opening 11. Since the latch rod 251 is located on the lower side of the corresponding inner convex support edge 211, that is, the latch rod 251 is located on the lower side of the front air filter 22, the latch rod 251 is exposed at the top of the pet holding cavity 10. The user can easily pinch the latch rod 251 with his / her hand, and then move the latch rod 251 located on the left to the right, and then move the latch rod 251 located on the right to the left, so that the latch rod 251 is disengaged from the corresponding locking hole 311, so that the support frame 21 can swing downward to open.
