[0002] With the improvement of living and medical conditions, life expectancy continues to increase, and the aging process of the world's population is gradually accelerating. For many elderly and sick people, they may have difficulty in moving, and the number of disabled and demented elderly people is increasing. How to take care of their lives meticulously is a top priority. Home care device toilets can effectively solve the cleaning of the elderly's personal hygiene problems and allow the elderly to maintain a high level of personal dignity.

[0003] Existing household care device toilets usually include a toilet, a waste box and a vacuum generator. The vacuum generator uses compressed air to produce a suction effect, forming a negative pressure in the waste box, thereby sucking the waste in the toilet into the waste box. However, the compressed air system is huge in size. In order to maintain the vacuum degree of the waste box, a vacuum sensor is required to monitor the pressure in the box in real time, resulting in a complex overall structure of the device and high price, which is not suitable for direct application in a home environment. Summary of the invention

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0022] See also Figure 1-Figure 3As shown, the present invention discloses a household care device, comprising a sewage suction pipe 2 for connecting to a toilet 1, a pinch valve 3 being provided on the sewage suction pipe 2, and a sewage suction container 4. In this embodiment, the sewage suction container 4 is a cylindrical structure, a piston body 51 is coaxially arranged with the sewage suction container 4, the sewage suction container 4 is provided with a connecting port 41 for connecting to the sewage suction pipe 2, and a piston body 51 which can reciprocate in a direction away from or close to the connecting port 41 is provided in the sewage suction container 4; in the sewage suction state, the pinch valve 3 is closed, the sewage suction pipe 2 is connected to the sewage suction container 4, the piston body 51 moves in a direction away from the connecting port 41, and a negative pressure is formed in the pipe section of the sewage suction pipe 2 between the pinch valve 3 and the three-way valve.

[0023] The sewage suction pipe 2 includes a negative pressure pipe section 21 located between the clamp valve 3 and the three-way valve and a connecting pipe 22 located between the toilet 1 and the three-way valve.

[0024] See also Figure 1-2 As shown, during the sewage suction process, the sewage suction pipe 2 is clamped by the clamping valve 3, and then the piston body 51 is moved to the right. At this time, the air in the negative pressure pipe section 21 is sucked into the pressure cylinder, thereby forming a negative pressure in the negative pressure pipe section 21. The negative pressure in this process can be adjusted by adjusting the available volume of the sewage suction container 4 and the negative pressure pipe section 21. In the present invention, the negative pressure generated is 0.5 Bar (-0.5 vacuum degree), and then the clamping valve 3 is opened, and the sewage in the toilet 1 is immediately sucked from the toilet 1 into the sewage suction container 4 under the action of the negative pressure.

[0025] In the present invention, by using the suction container 4 with the piston body 51 in combination with the pinch valve 3, a stable negative pressure can be formed in the suction pipe 2, eliminating the need for expensive vacuum sensors and complex control systems, and eliminating the need for compressed air, thereby eliminating the need for an accompanying compressed air supply source, greatly simplifying the structure of the vacuum generating device, simplifying the control, making the product structure more compact and small, and reducing the manufacturing and use costs.

[0026] See also Figure 2-Figure 3 As shown, as a preferred specific embodiment of the present invention, a valve body 7 is also provided between the sewage suction pipe 2 and the sewage suction container 4, and the valve body 7 is provided with a first interface 71, a second interface 72 and a third interface 73. The first interface 71 is connected to the sewage suction pipe 2, the second interface 72 is connected to the connecting port 41, and the third interface 73 is connected to the sewage storage container 8.

[0027] During the sewage suction process, the first interface 71 and the second interface 72 are connected, and the third interface 73 is closed, so that the negative pressure pipe section 21 of the sewage suction pipeline 2 is connected to the sewage suction container 4.

[0028] See also Figure 3As shown, after the dirt suction is completed, the first interface 71 is closed, and the second interface 72 and the third interface 73 are connected, so that the dirt suction container 4 is connected to the dirt storage container 8. At this time, the piston body 51 is moved to the left, and the air and dirt in the dirt suction container 4 are pushed into the dirt storage container 8. Then the piston body 51 is reset and can be used for the next dirt suction operation.

[0029] The present invention can store the dirt sucked multiple times by setting up the dirt storage container 8, thereby reducing the frequency of dumping the dirt. Through the interface switching of the valve body 7 and the reciprocating movement of the piston body 51, rapid switching between dirt suction and dirt collection can be achieved, making the product more convenient to use.

[0030] The valve body 7 is a three-way electromagnetic ball valve.

[0031] The piston body 51 is connected to a push-pull driving member 6 for driving the piston body 51 to move.

[0032] The push-pull driving member 6 is any one of an electric push rod, a hydraulic push rod or a cylinder.

[0033] A first limit switch 91 and a second limit switch 72 for limiting the movement of the piston body 51 are also provided in the dirt suction container 4. The stroke of the piston body 51 is limited by the first limit switch 91 and the second limit switch 72, thereby limiting the available container of the dirt suction container 4 and ensuring that a fixed vacuum degree can be achieved each time suction is performed.

[0034] The piston body 51 is sleeved with a DAS combined sealing ring 52 to ensure the sealing between the piston body 51 and the dirt suction container 4 .

[0035] The application of the above-mentioned home care device in treating patient excrement comprises the following steps:

[0036] Reference Figure 1-2 As shown, sewage suction: close the pinch valve 3, connect the first interface 71 and the second interface 72, close the third interface 73, move the piston body 51 away from the connection port 41, and form a negative pressure in the pipe section of the sewage suction pipe 2 between the pinch valve 3 and the three-way valve, then open the pinch valve 3, and the excrement in the toilet 1 is sucked into the sewage suction container 4;

[0037] Reference Figure 3 As shown, waste collection: close the pinch valve 3 and the first interface 71 , connect the second interface 72 and the third interface 73 , move the piston body 51 toward the connection port 41 , and push the excrement in the waste suction container 4 into the waste storage container 8 .

[0038] Of course, the principles and implementation methods of the present invention are described in this article using specific examples, and the description of the above embodiments is only used to help the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
