[0024] To make the technical means, creative features, achieved purposes and functions of this utility model easy to understand, the following further elaborates this utility model in combination with specific embodiments.
[0025] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present utility model.
[0026] The present utility model is a negative pressure sewage tank, mainly used as a fitting for a health care bed to absorb and collect the dirt in the toilet of the health care bed.
[0027] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the sewage tank mainly includes an outer box body 1, a sewage tank 2 and a negative pressure tank 3. The sewage tank 2 and the negative pressure tank 3 are both arranged inside the outer box body 1, forming an integrated structure, which is convenient for movement. Among them, the sewage tank 2 is used to collect and hold sewage. The negative pressure tank 3 is connected to the sewage tank 2, and the negative pressure tank 3 can generate negative pressure, so that the inside of the sewage tank 2 is also in a negative pressure state, thereby being able to absorb the dirt in the toilet under negative pressure and make the dirt enter the sewage tank 2.
[0028] Among them, the negative pressure tank 3 is connected to the sewage tank 2 and also to a negative pressure pump 4. The negative pressure pump 4 makes the inside of the negative pressure tank 3 generate negative pressure, and then makes the inside of the sewage tank 2 generate negative pressure. Specifically, the negative pressure tank 3 is connected to the sewage tank 2 through a negative pressure pipeline 6; the sewage tank 2 is connected to the sewage discharge port of the toilet through a sewage collection pipeline 5. Both the negative pressure tank 3 and the sewage tank 2 are hermetically arranged. In the specific implementation of the present utility model, preferably, the negative pressure pump 4 is arranged inside the outer box body 1, generally located below the sewage tank 2. The sewage collection pipeline 5 is connected to the sewage discharge port of the toilet through a pipeline, which can be in a continuously connected state, or a quick connector is arranged at the sewage collection pipeline 5. Each time it is used, the sewage collection pipeline 5 is quickly connected to the pipeline of the sewage discharge port of the toilet. It is preferably in a convenient disassembly and assembly manner.
[0029] In the specific implementation, such as Figure 3 、 Figure 4 As shown, preferably, the air inlet of the negative pressure pipeline 6 inside the sewage tank 2 is located in the upper part of the inside of the sewage tank 2. The negative pressure pipeline 6 passes downward through the bottom plate of the sewage tank 2, and then passes upward through the bottom plate of the negative pressure tank 3 and enters the inside of the negative pressure tank 3.
[0030] Preferably, the sewage collection pipeline 5 passes through the lower part of the sewage tank 2 and enters the inside of the sewage tank 2, and then extends upward. The outlet of the sewage collection pipeline 5 inside the sewage tank 2 is located in the upper part of the inside of the sewage tank 2. Further, such as Figure 3 、 Figure 4As shown, the sewage collection pipe 5 penetrates through the lower bottom plate of the sewage tank 2 and extends upward, and then an elbow 7 is provided at the upper end, so that the outlet of the sewage collection pipe 5 faces downward, which is conducive to the entry of dirt into the sewage tank 2.
[0031] This utility model is used for collecting dirt. Since the dirt has a strong odor, in order to reduce the external discharge of the odor, usually a deodorant is provided in the negative pressure tank 3. When the negative pressure pump 4 pumps air, the gas inside the sewage tank 2 first enters the negative pressure tank 3, and deodorization treatment is carried out in the negative pressure tank 3, and then it is discharged outside through the negative pressure pump 4. In a specific implementation, usually activated carbon is provided in the negative pressure tank 3 as a deodorant.
[0032] For the sewage tank 2 of this utility model, a sealing cover 8 is provided at its upper end. And, a sewage discharge port 9 is also provided on the sealing cover 8, and the sewage discharge port 9 is tightened and sealed with a lid. When it is necessary to pour out the sewage in the sewage tank 2, the sewage tank 2 is taken out, the lid on the sewage discharge port 9 is unscrewed, and the sewage tank 2 is inverted.
[0033] Usually, a handle 10 is provided on the sealing cover 8 to facilitate the taking and placing of the sewage tank 2.
[0034] The sewage tank 2 needs to be taken and placed. Therefore, the sewage tank 2 is a split structure relative to the outer box body 1, and the sewage tank 2 is placed inside the outer box body 1. The negative pressure tank 3 does not need to be taken and placed, and the negative pressure tank 3 and the outer box body 1 can be either split or integrated. If the negative pressure tank 3 and the outer box body 1 are of an integrated structure, then a space is separated inside the outer box body 1 as the negative pressure tank 3.
[0035] In this utility model, in a specific implementation, usually an end cover 11 is provided at the upper end of the outer box body 1, so that the whole sewage tank is an integrated box body, and the appearance is relatively simple. Universal wheels 12 are provided at the lower part of the outer box body 1 to facilitate movement.
[0036] When this negative pressure sewage tank is in operation, mainly the negative pressure pump is started. One-key operation can be realized by the control system.
[0037] This utility model is a sewage tank used in cooperation with a healthcare bed. By adopting the negative pressure suction method, it can conveniently adsorb and collect the sewage in the toilet of the healthcare bed, and has good usability.
[0038] The above shows and describes the basic principles, main features and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of this utility model. Without departing from the spirit and scope of this utility model, this utility model will have various changes and improvements, and these changes and improvements all fall within the scope of this utility model claimed. The scope of protection claimed by this utility model is defined by the appended claims and their equivalents.
