Referring to fig. 1-5, the invention relates to an odor sealing cover device for a feces storage part of a sanitary dry toilet, which comprises a storage bin 1 and a quantitative feeding bin 2, wherein the storage bin and the quantitative feeding bin are respectively used for storing covering materials and quantitatively feeding the covering materials; the downside of storage storehouse 1 is equipped with first material mouth 11, quantitative feeding storehouse 2 is located storage storehouse 1's downside, cover material in storage storehouse 1 can pass through first material mouth 11 enters into extremely in the quantitative feeding storehouse 2, 11 departments of first material mouth are provided with and are used for opening or seal first material mouth 11's first apron 12, the downside of quantitative feeding storehouse 2 is equipped with second material mouth 21, 21 departments of second material mouth are provided with and are used for opening or seal the second cover plate 22 of second material mouth 21, cover material in the quantitative feeding storehouse 2 can pass through second material mouth 21 is thrown in to the manure pit to cover excrement and urine in the manure pit.

The volume of storage storehouse 1 is greater than the volume that storehouse 2 was put in to the ration, and storage storehouse 1 can save the covering material in a large number, and the covering material that storehouse 2 was put in to the ration usually can only satisfy the single and put in, and the covering material in the storage storehouse 1 shifts to the ration through first material mouth 11 and puts in storehouse 2, and this transfer process is: the first cover plate 12 is opened, the second cover plate 22 is closed (shown in fig. 7), the storage bin 1 is communicated with the quantitative feeding bin 2 through the first material opening 11, and the covering material in the storage bin 1 slides into the quantitative feeding bin 2 through the first material opening 11 under the action of self gravity until the covering material in the storage bin 1 cannot be continuously filled into the quantitative feeding bin 2; and when putting in the manure pit with the covering material of ration in storehouse 2, second apron 22 is opened, first apron 12 is closed (shown in fig. 8), the covering material of ration in storehouse 2 just drops in to the manure pit through second material mouth 21, at this moment, the covering material in the storage storehouse 1 can't get into the ration through first material mouth 11 and drops in storehouse 2, therefore only the covering material of ration in storehouse 2 at most is all dropped in to the manure pit, thereby the upper limit of the covering material of single input to the manure pit has been injectd, prevent to cause the single to drop in the covering material too much and cause the waste.

The covering material can cover the excrement after being put into the septic tank, thereby playing the purpose of isolating the peculiar smell of the excrement. The covering material can be degradable organic waste such as straw powder, rice husk, bamboo shoot shell (crushed into powder) and the like, and can be mixed with a certain amount of leavening agent.

Referring to fig. 1, the storage bin 1 may further include a feeding port 13, an operator may supplement the covering material into the storage bin 1 through the feeding port 13, and the feeding port 13 may be sealed by a corresponding feeding cover 14.

In a preferred embodiment, referring to fig. 1, 7 and 8, the odor sealing device for the sanitary dry toilet feces storage area further comprises a control mechanism 5 for controlling the opening and closing state of the first cover plate 12 and the second cover plate 22; the storage bin 1 with the ration is put in 2 fixed connection in the storehouse, first via hole has been seted up to the upper wall in storage bin 1, control mechanism 5 includes control lever 51, control lever 51 passes first via hole, the lower part of control lever 51 respectively with first apron 12 with second apron 22 is connected, control lever 51 can reciprocate in order to control first apron 12 with the state that opens and shuts of second apron 22. The lower end of the control rod 51 is connected with the first cover plate 12 and the second cover plate 22 respectively, and the operator can operate the control rod 51 to move up and down, and drive the first cover plate 12 and the second cover plate 22 to move up and down through the control rod 51, so that the opening and closing states of the first cover plate 12 and the second cover plate 22 are switched, and the feeding of the covering material is controlled. The opening and closing states of the first cover plate 12 and the second cover plate 22 can be controlled simultaneously by arranging the independent control rod 51, the first cover plate 12 and the second cover plate 22 do not need to be controlled by two control mechanisms respectively, and the complexity of the structure of the control mechanism 5 is greatly simplified.

In addition, the open-close state of the first cover plate 12 is just opposite to the open-close state of the second cover plate 22, and if the first cover plate 12 is in the closed state, the second cover plate 22 is in the open state; when the first cover plate 12 is in the open state, the second cover plate 22 is in the closed state, and the open-close states of the first cover plate 12 and the second cover plate 22 are controlled by one control rod 51, so that the open-close states of the first cover plate 12 and the second cover plate 22 are related to each other, thereby ensuring that the open-close states of the first cover plate 12 and the second cover plate 22 are always opposite to each other, and preventing the first cover plate 12 and the second cover plate 22 from being in the open state or being in the closed state at the same time.

Further, referring to fig. 3 to 8, the first cover plate 12 closes the first material opening 11 from bottom to top, and the second cover plate 22 closes the second material opening 21 from top to bottom; in a natural state, the first material port 11 is opened by the first cover plate 12, and the second material port 21 is closed by the second cover plate 22; the control rod 51 is lifted up to drive the first cover plate 12 and the second cover plate 22 to move upwards so as to close the first material opening 11 and open the second material opening 21.

The first cover plate 12 is located at the lower side of the first material opening 11, the second cover plate 22 is located at the upper side of the second material opening 21, and in a natural state (without external force), the second cover plate 22 is influenced by its own gravity, the second cover plate 22 covers the second material opening 21 from top to bottom (shown in fig. 7), thereby closing the second material opening 21, i.e., the second cover 22 is in the closed state, in which the control rod 51 is at the lowest position, since the first cover 12 is connected to the control rod 51, the first cover 12 is also at the lowest position, since the first cover plate 12 is located at the lower side of the first material opening 11, the first cover plate 12 does not cover the first material opening 11, therefore, the storage bin 1 is communicated with the quantitative feeding bin 2 through the first material port 11, the covering material in the storage bin 1 can flow into the quantitative feeding bin 2 through the first material port 11, and the covering material in the quantitative feeding bin 2 cannot flow out through the second material port 21. When covering materials need to be put into the septic tank, an operator lifts the control rod 51 upwards, the control rod 51 drives the first cover plate 12 and the second cover plate 22 to move upwards, the first cover plate 12 is upwards close to the first material opening 11, the second cover plate 22 is upwards far away from the second material opening 21 until the first cover plate 12 seals the first material opening 11 (shown in fig. 8), at the moment, the control rod 51 is limited by the first cover plate 12 and the first material opening 11 and cannot move upwards, the opening degree between the second cover plate 22 and the second material opening 21 is the maximum, namely, the second cover plate 22 is in an open state, the first cover plate 12 is in a closed state, the covering materials in the quantitative putting-in bin 2 can be put into the septic tank through the second material opening 21, and the covering materials in the storage bin 1 cannot enter the quantitative putting-in bin 2 through the first material opening 11.

It is easily understood that the second cover plate 22 is in a normally closed state (corresponding to the second material opening 21 being closed, as shown in fig. 7), and the first cover plate 12 is in a normally open state (corresponding to the first material opening 11 being open), so as to ensure that a certain amount of covering material can be pre-stored in the quantitative feeding bin 2, when the covering material is fed, the control rod 51 is lifted, so that the second cover plate 22 is in an open state, the first cover plate 12 is in a closed state, so as to feed the covering material in the quantitative feeding bin 2 into the septic tank, after the feeding is completed, the control rod 51 is released, the first cover plate 12, the second cover plate 22 and the control rod 51 move downward under the action of their own gravity, and the second cover plate 22 re-closes the second material opening 21, and the first cover plate 12 opens the first material opening 11.

In a preferred embodiment, referring to fig. 3, 4, 7 and 8, the middle region of the second cover plate 22 is upwardly protruded, and the lower end of the lever 51 is fixedly coupled to the protruded portion of the second cover plate 22. Because second apron 22 is in the normally closed state, the covering material in the storehouse 2 is put in to the ration is piled up in the top of second apron 22, drive second apron 22 upward movement at control lever 51, in order to open second material mouth 21, if second apron 22 is platelike structure, second apron 22 upwards translation, the covering material majority in the storehouse 2 is put in to the ration can be followed second material mouth 21 and is put in to the manure pit, but the upside of second apron 22 still can gather a certain amount of covering material, thereby lead to the unable whole manure pits of putting in the storehouse 2 of ration, and when lifting up second apron 22, also overcome the gravity of the covering material of gathering on the second apron 22, increase operating personnel's the degree of difficulty of controlling. And the middle area of the second cover plate 22 is raised upwards, so that when the second cover plate 22 is in an open state, the covering material on the second cover plate 22 cannot be attached to the upper part of the second cover plate 22, the covering material in the quantitative feeding bin 2 can be smoothly fed into the septic tank, and the difficulty in operation of operators is also reduced.

It can be understood that the upper side surface of the second cover plate 22 is high in the middle and low in the periphery, and the upper side surface of the second cover plate 22 may be a hemispherical surface or a conical surface with a sharp upper part and a wide lower part. The lower extreme of control lever 51 can be with the highest point fixed connection of second apron 22, and during the up-and-down motion of control lever 51, whole drive second apron 22 up-and-down motion to the realization is controlled opening and shutting of second material mouth 21.

Further, referring to fig. 5 and 6, a side of the first cover plate 12 is hinged to a side of the first material opening 11, the first cover plate 12 is provided with a through slot 15, the control rod 51 passes through the through slot 15, the control rod 51 is connected with a blocking block 53, the blocking block 53 is located on the lower side of the first cover plate 12, the upper side of the blocking block 53 is abutted to the lower side of the first cover plate 12, and the length direction of the through slot 15 is perpendicular to the side of the first cover plate 12 hinged to the first material opening 11.

The stop 53 of the lever 51 supports the first cover 12, and when the lever 51 moves up and down, the lever 51 also supports the first cover 12 to move up and down. Specifically, the first cover plate 12 rotates relative to a hinged side thereof, so as to control the opening and closing of the first cover plate 12, because the first cover plate 12 can only rotate relative to the hinged side thereof, and the control rod 51 can only move up and down, when the control rod 51 drives the first cover plate 12 to rotate up and down, the support block can move relative to the first cover plate 12 along the length direction of the through groove 15, and the design of the through groove 15 can ensure that the control rod 51 can smoothly drive the first cover plate 12 to rotate.
