Please refer to FIG. 1, an embodiment of the present invention provides a placing device 10. The placing device 10 includes a storage tube 11, a discharging channel 14 and a movable assembly 15.

The storage pipe 11 is formed with a storage channel 111, and the storage channel 111 is used to store a plurality of solid detergents. The solid detergent in the storage channel 111 can enter the discharge channel 14. The movable assembly 15 is arranged in the unloading channel 14. The movable assembly 15 can move to isolate or communicate with the unloading channel 14. When the movable assembly 15 connects the unloading channel 14, the solid detergent in the unloading channel 14 is discharged from the unloading channel 14 The inside of the channel 14 falls to the outside of the unloading channel 14; the movable assembly 15 can block the material outside the unloading channel 14 from entering the storage tube 11 through the unloading channel 14 when the unloading channel 14 is blocked.

In the dispensing device 10 of the embodiment of the present invention, the discharging channel 14 is blocked or connected through the movable assembly 15 to facilitate the control of the movement of the solid detergent in the discharging channel 14. Moreover, when the movable assembly 15 cuts off the unloading channel 14, the material outside the unloading channel 14 is blocked by the movable assembly 15, and it is difficult to affect the solid detergent in the storage channel 111.

Specifically, the discharging channel 14 is formed with a discharging port 141, and the solid detergent in the discharging channel 14 drops from the discharging port 141 to the outside of the discharging channel 14.

In this embodiment, the “material outside the unloading channel 14” includes water vapor, dust, washing dirt, and the like. The specific form of the "material outside the feeding channel 14" is not limited here.

It can be understood that in the process of putting solid detergent, since the solid detergent can enter the discharging channel 14 from the storage channel 111, and then fall from the discharging port 141 to the outside of the discharging channel 14, therefore, the discharging channel 14 is outside. The substance is also easy to enter the feeding channel 14 from the feeding opening 141 from outside the feeding channel 14, and then into the storage channel 111, thereby affecting the solid detergent in the feeding channel 111.

For example, the water vapor outside the discharging channel 14 enters the discharging channel 14 through the discharging port 141, and then enters the material storage channel 111, so that the solid detergent in the material storage channel 111 becomes damp. For another example, the dust outside the feeding channel 14 enters the feeding channel 14 through the feeding opening 141, and then enters the feeding channel 111, so that the solid detergent in the feeding channel 111 is stained with dust. For another example, the washing dirt outside the unloading channel 14 enters the unloading channel 14 through the unloading port 141, and then enters the storage channel 111, so that the solid detergent in the storage channel 111 is contaminated.

In this way, the solid detergent in the storage channel 111 is easily affected and the quality is reduced, so that the washing effect of the solid detergent injected by the injection device 10 is poor.

The unloading channel 14 is blocked or connected by the movable assembly 15, so that when the movable assembly 15 separates the unloading channel 14, the material outside the unloading channel 14 is blocked by the movable assembly 15, and the unloading channel 14 is blocked by the movable assembly 15 When connected, the solid detergent in the discharging channel 14 can fall from the discharging channel 14 to the outside of the discharging channel 14. In this way, the solid detergent in the storage channel 111 can be protected from external influences, and the normal delivery of the dispensing device 10 can be ensured.

In this embodiment, the dispensing device 10 is formed with a sliding channel (not shown in the figure), and the sliding channel is in communication with the discharging channel 14. The movable assembly 15 is used to move into the unloading channel 14 through the sliding channel to isolate the unloading channel 14, and the movable assembly 15 is used to move from the unloading channel 14 to the outside of the unloading channel 14 through the sliding channel to make the unloading channel 14 Connected.

In this way, the movement of the movable assembly 15 is guided by the sliding channel, which can prevent the movement of the movable assembly 15 from being deviated and the movable assembly 15 cannot block the feeding channel 14 or has a poor blocking effect, which is beneficial to improve the activity of the movable assembly 15. Stability and accuracy, so that the cutting effect of the feeding channel 14 is better.

Further, the sliding channel through which the movable assembly 15 moves into the unloading channel 14 may be the same as the sliding channel through which the movable assembly 15 moves from the unloading channel 14 to the outside of the unloading channel 14.

For example, the movable assembly 15 is used to move into the unloading channel 14 through a sliding channel in the first direction to isolate the unloading channel 14, and the movable assembly 15 is used to move from the unloading channel 14 to the next through the sliding channel in the second direction. The material passage 14 is outside so that the discharging passage 14 is connected, and the first direction is opposite to the second direction.

In this way, the movable assembly 15 always reciprocates in the same sliding channel, but the directions of sliding in and out are different, and there is no need to provide multiple sliding channels, which is beneficial to improve production efficiency. Moreover, such a structure and movement mode are relatively simple, which can avoid easy failure due to excessively complicated movement modes.

It can be understood that in other embodiments, the sliding channel may include a first sliding channel and a second sliding channel. The movable assembly 15 is used to move into the unloading channel 14 in the first direction through the first sliding channel to isolate the unloading channel 14, and the movable assembly 15 is used to move from the unloading channel 14 to the outside in the first direction through the second sliding channel. Move so that the unloading channel 14 communicates. The movable assembly 15 is used to move into the unloading channel 14 again in the second direction through the second sliding channel to block the unloading channel 14 again, and the movable assembly 15 is used to move from the unloading channel 14 in the second direction through the first sliding channel. The inside moves to the outside again to make the discharging channel 14 communicate again, and the first direction is opposite to the second direction.

In this way, the movable assembly 15 can always move in one direction in the unloading channel 14, providing another movement mode, which makes the movement modes of the movable assembly 15 more abundant, which can be selected according to actual needs.

The specific manner in which the movable component 15 moves in the sliding channel is not limited here.

In some embodiments, the movable assembly 15 includes a first movable block 16 and a second movable block 17. The first movable block 16 and the second movable block 17 are arranged at intervals in the unloading channel 14, and the first movable block 16 is located in the first movable block 16 and the second movable block 17. Between the two movable blocks 17 and the storage channel 111, when the first movable block 16 connects the unloading channel 14, the second movable block 17 blocks the unloading channel 14; the second movable block 17 makes the unloading channel When 14 is connected, the first movable block 16 blocks the feeding channel 14.

In this way, the unloading channel 14 is always blocked by one of the first movable block 16 and the second movable block 17, so as to ensure that water vapor, dirt and other substances cannot always pass through the unloading channel 14 to penetrate into the storage channel 11, thereby ensuring the storage of materials. The quality of the solid detergent in the channel 11.

It can be understood that when the second movable block 17 connects the unloading channel 14, the first movable block 16 blocks the unloading channel 14, so that water vapor, dust, washing dirt and other substances are always blocked by the first movable block 16. It is not possible to penetrate the feeding channel 14 into the storage channel 11.

When the first movable block 16 connects the unloading channel 14, the second movable block 17 blocks the unloading channel 14, so that water vapor, dust, washing dirt and other substances are always blocked by the second movable block 17 and cannot pass through. The material channel 14 penetrates into the material storage channel 11.

In this embodiment, the specific movement modes of the first movable block 16 and the second movable block 17 are shown in FIGS. 1 to 5.

The first movable block 16 and the second movable block 17 in FIG. 1 are in the initial positions at the beginning of each cycle. Specifically, the first movable block 16 is at the leftmost position, so that the unloading channel 14 is connected, and the second movable block 17 is at the rightmost position, so that the unloading channel 14 is blocked;

After that, the first movable block 16 moves to the right to the middle position to block the unloading channel 14 while the second movable block 17 moves to the left to the middle position to block the unloading channel 14 to form a double seal, as shown in Figure 2 Shown

After that, the first movable block 16 continues to move to the right to the rightmost position to block the unloading channel 14, while the second movable block 17 continues to move to the left to the leftmost position, so that the unloading channel 14 is connected, as shown in Figure 3. Shown

After that, the first movable block 16 moves to the left to the middle position to block the unloading channel 14 while the second movable block 17 moves to the right to the middle position to block the unloading channel 14 to form a double seal, as shown in Figure 4 Shown

Finally, the first movable block 16 continues to move to the left to the leftmost position to connect the discharging channel 14 while the second movable block 17 continues to move to the right to the rightmost position to block the discharging channel 14, as shown in Figure 5 As shown, the loop ends.

After the loop in FIG. 5 ends, the positions of the first movable block 16 and the second movable block 17 are the same as the initial positions of the first movable block 16 and the second movable block 17 in FIG. 1. In this way, the first movable block 16 and the second movable block 17 can move in the same manner as described above in each cycle.

It can be understood that in other embodiments, the first movable block 16 and the second movable block 17 may be moved in other ways. The specific movement modes of the first movable block 16 and the second movable block 17 are not limited here.

In this embodiment, the shape of the cross section of the first movable block 16 is the same as the shape of the cross section of the blanking channel 14, and the shape of the cross section of the second movable block 17 is the same as the shape of the cross section of the blanking channel 14.

In this way, the first movable block 16 and the second movable block 17 are adapted to the shape of the blanking channel 14 in the case where the blanking channel 14 is partitioned, so that the partitioning effect is better.

The size of the cross section of the first movable block 16 is the same as the size of the cross section of the blanking channel 14, and the size of the cross section of the second movable block 17 is the same as the size of the cross section of the blanking channel 14.

In this way, the first movable block 16 and the second movable block 17 are adapted to the size of the blanking channel 14 in the case where the blanking channel 14 is partitioned, and the gap is small, so that the partitioning effect is better.

For example, in the case where the cross section of the first movable block 16 and the cross section of the blanking channel 14 are both rectangular, the length of the cross section of the first movable block 16 is the same as the length of the cross section of the blanking channel 14, the first The width of the cross section of the movable block 16 is the same as the width of the cross section of the unloading channel 14.

For another example, when the cross section of the first movable block 16 and the cross section of the blanking channel 14 are both circular, the diameter of the cross section of the first movable block 16 is the same as that of the blanking channel 14.

The above are all descriptions of "the size of the cross section of the first movable block 16 is the same as the size of the cross section of the blanking channel 14", and does not represent a limitation on the shape of the cross section of the first movable block 16 and the blanking channel 14 .

Please note that the explanation and description of "the size of the cross-section of the second movable block 17 is the same as the size of the cross-section of the discharging channel 14" can be referred to the previous text. To avoid redundancy, it will not be repeated here.

In addition, the shape of the cross section of the discharging channel 14 may be the same as the shape of the cross section of the solid detergent. In this way, the space of the blanking channel 14 can be fully utilized, and the larger space occupied by the blanking channel 14 caused by the unsuitable shape can be avoided.

Furthermore, the size of the cross section of the discharging channel 14 is larger than the size of the cross section of the solid detergent. In this way, the solid detergent can be smoothly dropped from the discharging channel 14 to avoid being caught by the discharging channel 14 due to the size of the solid detergent being too large.

In this embodiment, the shape of the cross section of the solid detergent, the shape of the cross section of the discharging channel 14, and the shapes of the first movable block 16 and the second movable block 17 are all rectangular.

It can be understood that in other embodiments, the shape of the cross section of the solid detergent, the shape of the cross section of the discharging channel 14, the shape of the first movable block 16 and the second movable block 17 may also be circular or elliptical. , Triangle or other shapes are not limited here.

In addition, the first movable block 16 and the second movable block 17 may have a plate shape. In this way, the size of the first movable block 16 and the second movable block 17 in the drop direction of the solid detergent is small, that is, the first movable block 16 and the second movable block 17 are thinner, so that the first movable block 16 and the second movable block 16 are thinner. The space required for the movement of the two movable blocks 17 is relatively small, which is beneficial to saving the internal space of the dispensing device 10.
