On the other hand, on the basis of ensuring the sealing and unobstructed between the conveying hole 15 and the annular space 30, it is also advantageous to appropriately increase the diameter of the conveying hole 15, thereby facilitating the mold making of the body 10.

Further, the upper end of the transition hole 41 is in abutting communication with the lower end of the delivery hole 15, as shown in FIG.

The upper end of the transition hole 41 is in abutting communication with the lower end of the conveying hole 15, that is, the sealing member 40 is directly butted and sealed with the body 10, which simplifies the structure of the sealing member 40, and is convenient for processing and assembly.

The ratio of the aperture d1 of the lower end of the delivery hole 15 to the aperture d of the adapter hole 16 is greater than 1.5. In this case, the aperture of the delivery aperture 15 is substantially different from the size of the adapter aperture 16, and the aperture of the delivery aperture 15 is significantly larger than The aperture of the through hole 16 causes the pressure in the conveying hole 15 to be small, which is disadvantageous for the smooth flow of the material; at this time, by providing the projection 42 on the sealing member 40, the projection 42 is inserted into the conveying hole 15, which is equivalent. The hole diameter of the conveying hole 15 is appropriately reduced, thereby avoiding the situation that the material conveying is not smooth due to the large deviation between the conveying hole 15 and the adjusting hole 16, and the smoothness of material conveying is improved.

Further, the diameter of the transition hole 41 gradually decreases from the bottom to the top as shown in FIGS. 7 and 15.

As before, since the adapter hole 16 is to be connected to an external pipe or a power source, the aperture of the adapter hole 16 will be relatively small to facilitate the assembly of the external pipe or the power source; and to facilitate the flow of material, the annular space 30 The upper end outlet and/or the inlet may be appropriately enlarged, so that the cross-sectional area of the transition hole 41 is gradually decreased from the bottom to the top, corresponding to the size of the annular space 30 below and the transfer hole 16 above it. Therefore, it also plays a good excessive role, which is conducive to further improve the smoothness of material flow.

An outer cover 20 is added on the outer side of the body 10. An annular space 30 is defined between the outer cover 20 and the body 10. The annular space 30 communicates with the inner space of the body 10 through the through hole 11, so that an outer space is formed on the outer side of the body 10. The cavity is provided with a delivery port on at least one of the body 10 and the outer cover 20, and the top of the annular space 30 is provided with a cutout 21, and the upper end of the avoidance slot 23 communicates with the delivery port, thereby realizing the delivery port. The communication with the annular space 30 can thus utilize the cavity to transport material (including but not limited to airflow, water flow, etc.) to the interior of the body 10, or utilize the cavity to materialize the interior of the body 10 (including but not limited to In the prior art, the pipe is inserted into the rice washing box (corresponding to the body 10 of the present application), thereby improving the space utilization inside the body 10 and simplifying the body. At the same time, since the escaping groove 23 communicates with the conveying port and the annular space 30, and the central axis of the conveying port passes longitudinally through the escaping groove 23, the escaping groove 23 can provide a good cushioning effect and improve Material is transported Excessive smoothness with the annular space 30, thereby improving the efficiency of material transport; especially in the case where the transport port is located outside the annular space 30 and the longitudinal spacing between the annular space 30 is too large, Since the central axis of the delivery port is offset from the annular space 30, the drainage is not easy or the intake air is not smooth, and the arrangement of the avoidance slot 23 plays a good space compensation function, ensuring that the annular space 30 can The central axes of the delivery ports coincide, so as to avoid the above-mentioned poor drainage or poor air intake.

Further, the groove wall of the avoidance groove 23 is a curved surface as shown in FIGS. 1, 2, 18 and 20.

The groove wall of the avoidance groove 23 is a curved surface, which facilitates the material to flow upward along the side wall of the avoidance groove 23 (such as washing sewage) or downward flow (such as air flow), and is not easy to generate eddy current, etc., thereby ensuring that the material can be quickly and smoothly The ground is excessively transferred from the delivery port into the annular space 30 or from the annular space 30 to the delivery port, thereby further improving the material transport efficiency.

Further, the central axis of the delivery port extends in the vertical direction, and the slope of the longitudinal section of the groove wall of the escape groove 23 gradually increases from the bottom to the top as shown in FIGS. 18 and 20.

Preferably, the tangent to the vertex portion of the longitudinal section of the groove wall of the avoidance groove 23 is parallel to the central axis of the delivery port, as shown in FIGS. 18 and 20.

The central axis of the conveying port extends in the vertical direction. Accordingly, the slope of the longitudinal section of the groove wall of the escaping groove 23 gradually increases from the bottom to the top, and gradually approaches the central axis of the conveying port, which is advantageous for improving the material at the conveying port and Excessive smoothness between the avoidance slots 23, thereby further improving the efficiency of material transport.

The space 30 is further discharged by the first drain port 12. Since the size of the through hole 11 is smaller than the size of the material such as rice, the annular space 30 can pass through the water, but cannot pass through the material, so only the washing sewage can pass through the drain. The hole 11 enters the annular space 30, thereby realizing the separation of the cleaning sewage and the materials such as rice, and avoiding the materials such as rice reaching the first drainage port 12, so that the situation that the rice and the like block the water suction port does not occur, so that the cleaning is performed. Sewage can be quickly discharged.
