DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings:

[0017] Referring to the accompanying drawings: this drying and cleaning cover includes a cover body 1, and also includes a first connecting pipe 2, a second connecting pipe 3, and an air inlet pipe 4. The first connecting pipe 2 is integrally formed at the center of the upper end of the cover body 1, and the second connecting pipe 3 is connected to the first connecting pipe 2. An extension pipe 31 perpendicular to the extension direction of the second connecting pipe 3 is provided on the outer circumference of the second connecting pipe 3, and an exhaust pipe 5 is provided on the extension pipe 31. The air inlet pipe 4 passes through the first connecting pipe 2 and the second connecting pipe 3 at the same time and is connected to the second connecting pipe 3;

[0018] Connecting components 6 are provided between the first connecting pipe 2 and the second connecting pipe 3, between the second connecting pipe 3 and the air inlet pipe 4, and between the extension pipe 31 and the air exhaust pipe 5 to prevent separation after connection. The connecting components 6 are locked by plugging.

[0019] The principle of the utility model is that the cover body 1 is used to be connected with the hopper cover, that is, the port of the hopper is closed, and the first connecting pipe 2 makes the cover body 1 have a part connected with the second connecting pipe 3, and the second connecting pipe 3 is passed through and connected with the air inlet pipe 4, and the connection prevents the air inlet pipe 4 from swinging when the drying hot air passes through, and the two use the size difference to form a gap, which serves as a space for the drying air to enter during exhaust, and the inlet of the extension pipe 31 connected to the exhaust pipe 5 is connected to the space, so as not to be confused with the hot air, and the connecting component 6 is used to realize the connection between the first connecting pipe 2 and the second connecting pipe 3, between the second connecting pipe 3 and the air inlet pipe 4, and between the extension pipe 31 and the exhaust pipe 5, and the matching form is plug-in, which is more convenient than the connection form of bolts.

[0020] The connecting assembly 6 includes a first connecting plate 61 and a second connecting plate 62. The first connecting tube 2, the second connecting tube 3, and the extension tube 31 are all provided with the first connecting plate 61. The second connecting tube 3, the exhaust tube 5, and the air inlet tube 4 are all provided with the second connecting plate 62. A locking structure 63 is provided between the first connecting plate 61 and the second connecting plate 62 to prevent separation after the two are combined. The first connecting plate 61 and the second connecting plate 62 enable the components that need to be interconnected to have an additional setting part, and the setting part is used to set the locking structure 63, so that the components that need to be interconnected will not be separated after being combined through the locking structure 63, thereby ensuring the structural integrity of the overall structure.

[0021] The locking structure 63 includes a plurality of positioning posts 631 formed on the first connection disk 61 and distributed along its circumference, and positioning holes 632 formed on the second connection disk 62 and distributed along its circumference and matched with the positioning posts 631. The upper end of the positioning post 631 is provided with a locking pressure head 6311 that can be squeezed and deformed. When the positioning hole 632 passes through the locking pressure head 6311, the locking pressure head 6311 adapts to the size of the positioning hole 632 through squeezing and deformation, and returns to the initial state after the positioning hole 632 passes through, generating an upper end constraint on the second connection disk 62 so that the second connection disk 62 fits the first connection disk 61. After the positioning posts 631 are provided, the first connection disk 61 is used as a positioning component, and after the positioning holes 632 are provided, the second connection disk 62 is used as a positioned component, so that The two connecting disks can be connected together, and there is no need to adjust the use position of the two connecting disks after the connection. At the same time, in order to prevent the second connecting disk 62 from falling out after passing through the positioning column 631, a locking pressure head 6311 is set on the positioning column 631. The locking pressure head 6311 can be deformed by extrusion, that is, its initial size is larger than the size of the positioning hole 632, so its size can be reduced by extrusion to adapt to the size of the positioning hole 632, so that it is convenient for the positioning hole 632 to pass through during assembly or disassembly. In this way, the locking pressure head 6311 can use its own large size to limit the second connecting disk 62 at its lower end when it is not squeezed, so as to prevent the second connecting disk 62 from falling out. This method can realize a tool-free and parts-free assembly mode, which is suitable for quick and convenient assembly.

[0022] A socket 63111 combined with the positioning column 631 is provided at the center position of the lower end of the locking pressure head 6311. The socket 63111 enables the locking pressure head 6311 to be set on the positioning column 631 in a plug-in manner, and can be glued after connection, so that the locking pressure head 6311 can be stably present on the positioning column 631 regardless of whether the second connecting plate 62 is assembled or disassembled. At the same time, the part of the positioning column 631 inserted into the socket 63111 is a conical configuration, and the outer shape configuration of the socket 63111 is adapted thereto, so that the length of the positioning column 631 inserted into the socket 63111 can be increased, thereby increasing the gluing area, and making the connection stability between the two better.

[0023] The locking press head 6311 is made of rubber material. Such a setting can make the locking press head 6311 deform when squeezed, so as to achieve size adaptation, and return to the initial state after the squeezing is released (that is, after the positioning hole 632 passes through), and also prevent the second connecting plate 62 from escaping in the opposite direction of the assembly direction, so as to achieve quick matching and eliminate the cumbersomeness of bolts and auxiliary tools. When the second connecting plate 62 needs to be disassembled, it is only necessary to manually squeeze the locking press head 6311 to reduce its size to match the size of the positioning hole 632.

[0024] A water inlet pipe 7 is arranged in the air inlet pipe 4. The transverse section of the water inlet pipe 7 is located above the second connecting pipe 3 and passes through the air inlet pipe 4 so that the water inlet end is exposed to the outside. The vertical section of the water inlet pipe 7 passes through the air inlet pipe 4 so that the water outlet end is exposed to the outside and enters the hopper when the cover body 1 is closed on the hopper. A cleaning ball 71 is arranged at the water outlet end of the water inlet pipe 7. Such an arrangement can realize the air intake for drying and the exhaust at the same time, and can realize the function of cleaning water inlet. One cover has three uses, which optimizes the structure and saves manufacturing costs.

[0025] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
