[0030] This embodiment relates to a sewage discharge device, such as... Figures 1-6 As shown, it includes: a sewage tank 100, a negative pressure pump 200, a water suction pipe 300, and a drainage mechanism.
[0031] The sewage bucket 100 is internally provided with a cavity 110 capable of containing a certain amount of sewage; the negative pressure pump 200 is arranged above the sewage bucket 100 and is in communication with the cavity 110, capable of sucking the air inside the cavity 110 to generate negative pressure in the cavity 110; the water suction pipe 300 is arranged above the sewage bucket 100, one end of the water suction pipe 300 is in communication with the cavity 110, and the other end is inserted into a sewage source, for sucking sewage from the water suction pipe 300 into the cavity 110. The drainage mechanism comprises a drainage port 400 arranged at the bottom of the sewage bucket 100 and in communication with the cavity 110, and a control assembly 500 for controlling the opening and closing of the drainage port 400 to start and stop the drainage of sewage inside the cavity 110. When the drainage port 400 is closed, the negative pressure pump 200 sucks the air inside the cavity 110, negative pressure is formed inside the cavity 110, so that the sewage can be sucked through the water suction pipe 300 to enter the sewage cavity, realizing the suction of the sewage; then the control assembly 500 can be used to open the drainage port 400 to directly drain the sewage inside the cavity 110, realizing self-drainage of the drainage device, without manually draining the sewage inside the cavity 110, which is more simple and convenient to use. The drainage port 400 of the sewage device can be directly connected to a sewer or a sewage recycling tank.
[0032] In the embodiment, the control assembly 500 comprises a water blocking rod 510 and a driving member 520. The water blocking rod 510 is matched with the drainage port 400, and the water blocking rod 510 can be close to the drainage port 400 to block the drainage port 400, thereby stopping the drainage of the sewage inside the cavity 110, and the water blocking rod 510 can also be away from the drainage port 400 to enable the sewage inside the cavity 110 to be smoothly drained through the drainage port 400, realizing the drainage of the sewage inside the cavity 110. The driving member 520 is used to drive the water blocking rod 510 to be close to or away from the drainage port 400 to block or open the drainage port 400. As a preferred solution, the water blocking rod 510 is arranged above the drainage port 400, the driving member 520 is arranged above the sewage bucket 100, the upper portion of the water blocking rod 510 is in power connection with the driving member 520, and the water blocking rod 510 can be driven to move up and down to be close to or away from the drainage port 400, realizing the opening and closing of the drainage of the sewage inside the cavity 110, to realize good drainage effect. Specifically, the upper portion of the water blocking rod 510 is provided with a driving tooth 511, the driving member 520 comprises a driving motor 521 and an output gear 522 arranged on the output shaft of the driving motor 521, and the output gear 522 is in meshing connection with the driving tooth 511, to realize the power connection between the driving member 520 and the water blocking rod 510, achieving good drainage control effect.
[0033] As a preferred scheme, the water plugging rod 510 is provided with a spherical plug 512 at one end close to the drain port 400, and the spherical plug 512 can be well matched with the drain port 400. When the drain port 400 is plugged, the sealing between the spherical plug 512 and the drain port 400 is better, and a good plugging effect can be achieved. When the drain port 400 is closed, not only can the sewage inside the cavity 110 be prevented from being discharged from the drain port 400, but also air can be prevented from entering the cavity 110 from the drain port 400, thereby destroying the negative pressure effect inside the cavity 110 and affecting the water suction work of the water suction pipeline 300. The working stability of the drainage mechanism is better, and the use experience of the sewage discharge device is improved.
[0034] In the embodiment, the drain port 400 is arranged in the middle of the bottom of the cavity 110, so that the sewage inside the cavity 110 can be well discharged from the drain port 400 at the bottom. The guide slope 600 is arranged at the side of the drain port 400, which can guide the sewage inside the cavity 110 to the drain port 400. Not only can the drainage speed of the drain port 400 be increased to improve the working efficiency of the sewage discharge device, but also the sewage inside the cavity 110 can be completely discharged to avoid the residue of the sewage inside the cavity 110 to cause foreign matter and the like, thereby improving the use experience of the sewage discharge device.
[0035] As a preferred scheme, the negative pressure pump 200 is a diaphragm negative pressure pump 200, which can well suck the air inside the cavity 110 to form a negative pressure in the cavity 110 to suck the sewage into the cavity 110. The negative pressure pump 200 is arranged above the sewage bucket 100 and communicates with the upper part of the cavity 110, which can effectively prevent the sewage or impurities in the sewage in the cavity 110 from entering the negative pressure pump 200 to affect the air suction effect of the negative pressure pump 200, thereby ensuring the stable and efficient working effect of the negative pressure pump 200.
[0036] In the embodiment, a water level sensor is arranged in the cavity 110 to detect the sewage height in the cavity 110. The water level sensor is signal-connected with the drainage mechanism, so that when the sewage in the cavity 110 reaches the highest water level, the drain port 400 is opened to discharge the sewage in the cavity 110, and when the sewage in the cavity 110 reaches the lowest water level, the drain port 400 is closed to form a negative pressure in the cavity 110 to suck the sewage into the cavity 110 and continue the sewage discharge work. Specifically, the water level sensor includes a high water level sensor and a low water level sensor. The high water level sensor is used to detect the highest water level in the cavity 110, and the low water level sensor is used to detect the lowest water level in the cavity 110, so as to achieve a good water level detection effect.
[0037] In the embodiment, the switch assembly realizes the opening and closing of the drain port 400 by moving the water-stopping rod 510 close to or away from the drain port 400, and the water-stopping rod 510 is not easily blocked by impurities in the sewage, which affects the action of the water-stopping rod 510, so as to ensure that the switch assembly can work normally and has good stability. At the same time, when the switch assembly opens the drain port 400, it does not affect the drainage through the drain port 400, which not only ensures a faster drainage speed, but also enables most impurities to pass through the drain port 400 and be discharged, so as to avoid being blocked in the cavity 110 or the drain port 400, and achieve good drainage effect. In other embodiments, the control assembly 500 can also be an electromagnetic valve arranged at the drain port 400, which realizes the opening and closing of the drain port 400 by opening and closing the electromagnetic valve, so as to realize the opening and closing of the sewage discharge in the cavity 110.
[0038] As a preferred scheme, the control assembly 500 is arranged as a valve plate installed on the drain port 400 by an elastic member. When there is enough sewage in the cavity 110, the sewage can push the valve plate under the action of gravity, so as to compress the elastic member and open the drain port 400, thereby realizing the automatic discharge of the sewage in the cavity 110. When there is less sewage in the cavity 110, the elastic member can push the valve plate to block the drain port 400, so as to avoid the external air entering the cavity 110 through the drain port 400, and ensure that the suction pipeline 300 of the sewage treatment device can suck the sewage, thereby realizing good sewage treatment effect.
[0039] The above is only used to illustrate the technical scheme of the present application, but not limit the present application. Other modifications or equivalent replacements to the technical scheme of the present application made by those skilled in the art should be covered in the scope of the claims of the present application.
