FIG. DETAILED DESCRIPTION OF THE INVENTION

[0017] As shown in Figures 1 to 19, the nursing care machine of the present application includes a negative pressure source 30, a urine collection assembly 2, at least one control chip, an air supply pipe 4, an air pump 31, an air pressure sensor 320 for monitoring air pressure, a pressure relief valve 321 for reducing pressure, and at least one safety valve 322. The negative pressure source 30 is used to suck excrement from a human body. The urine collection assembly 2 is used to be worn on the human body to receive excrement from the human body. The urine collection assembly 2 includes an air cushion 200. The air cushion 200 is used to be placed on the human body and seal the connection between the urine collection assembly 2 and the human body, preventing excrement from leaking between the urine collection assembly 2 and the human body. The air supply pipe 4 is connected to the air cushion 200. The air pump 31 is used to inflate the air cushion 200. The air pump 31 inflates the air cushion 200 through the air supply pipe 4. The air pressure sensor 320 measures the air pressure of the air cushion 200 directly or the at least one control chip 141 is electrically connected to the first control chip 141, the air pressure sensor 320 is used to indirectly monitor the air pressure, the air pressure sensor 320 is electrically connected to the at least one control chip, the air pressure value monitored by the air pressure sensor 320 is output to the at least one control chip, the pressure relief valve 321 is used to directly or indirectly depressurize the air cushion 200, the at least one safety valve 322 is connected to the air supply line 4, the negative pressure source 30, the air pump 31 and the pressure relief valve 321 are controlled by the at least one control chip, and the at least one control chip 141 further includes a first control chip 141, the first control chip 141, the air pressure sensor 320, the air pump 31 and the pressure relief valve 321 are electrically connected to the first control chip 141, the air pressure value monitored by the air pressure sensor 320 is output to the first control chip 141, the air pump 31 and the pressure relief valve 321 are controlled by the first control chip 141, and the air pump 31 and the pressure relief valve 321 can be opened or closed under the control of the first control chip 141. The air pressure sensor 320 and the at least one control chip facilitate the air pump 31 to more accurately and controllably inflate the air cushion 200, and the pressure relief valve 321 and the at least one control chip facilitate easier and controllably deflating the air cushion.

[0018] The safety valve 322 is used to prevent the air pressure in the air supply line 4 from becoming too high, thereby indirectly preventing the air pressure in the air cushion 200 from becoming too high. The safety valve 322 is a mechanically opened and closed valve, which does not consume power and is not controlled by the at least one control chip, so it is not affected by electronic failures and is highly reliable. From another perspective, the safety valve 322 is used to limit the upper limit of the air pressure in the air supply line 4, and indirectly, the safety valve 322 is used to limit the upper limit of the air pressure in the air cushion 200. The safety valve 322 can improve safety, and if an electronic failure occurs in the care machine, the air pressure in the air cushion 200 will not be reduced due to continuous over-inflation. This is advantageous in preventing the air cushion 200 from bursting due to excessive pressure. The safety valve 322 has an opening threshold and a reset value. The opening threshold corresponds to the upper limit of the air pressure of the air cushion 200. The safety valve 322 opens when the corresponding air pressure reaches the opening threshold. When the corresponding air pressure drops below the reset value, the safety valve 322 returns to a closed state. In order for the safety valve 322 to open again, the air pressure in the air supply line 4 must rise to the opening threshold again. Based on the reset value, the safety valve 322 can return to a closed state in a more timely manner without requiring complete venting. This is advantageous in preventing waste caused by the safety valve 322 venting the air supply line 4 too much and in ensuring that the safety valve 322 closes when the next inflation is required. In this embodiment, the opening threshold of the safety valve 322 is 20 kPa (kilopascals), and the reset value is 8 kPa. That is, when the air pressure in the air supply line 4 reaches 20 kPa, the safety valve 322 opens to release the gas in the air supply line 4. When the air pressure in the air supply line 4 drops to 8 kPa, the safety valve 322 returns to a closed state. When the safety valve 322 opens, it has a fast exhaust speed, and the air pressure in the air supply line 4 can be reduced to the reset value in an extremely short time. Therefore, the safety valve 322 returns to a closed state in an extremely short time after opening. When the air pressure in the air supply line 4 reaches the opening threshold of the safety valve 322, the safety valve 322 opens at the air pressure in the air supply line 4 to release the gas in the air supply line 4. This avoids problems such as the air cushion 200 compressing the human body and causing the air cushion 200 to burst due to excessive air pressure in the air supply line 4 and the air cushion 200, and provides high safety.The present application does not provide an improvement to the safety valve 322 itself, and the safety valve 322 may be an existing product on the market. Similarly, the present application does not provide an improvement to the pressure relief valve 321 itself, and the pressure relief valve 321 may be an existing product. The pressure relief valve 321 is a controlled valve, and after the process of treating the patient's excrement is completed, the pressure relief valve 321 opens under the control of the at least one control chip to vent the air supply line 4 and the air cushion 200, causing the air cushion 200 to become collapsed, thereby relieving the pressure on the human body and making the human body comfortable. Thereafter, the pressure relief valve 321 closes under the control of the at least one control chip. When the care machine next begins the process of treating excrement, the at least one control chip controls the air pump 31 to inflate the air cushion 200.

[0019] The care machine further includes a main body 3, an air supply line 4 that can fluidly connect the main body 3 to the excrement collection assembly 2, an air pump 31, an air pressure sensor 320, a pressure relief valve 321, a safety valve 322, and a negative pressure source 30 that are each part of the main body 3 and located inside the main body 3, the at least one control chip being located inside the main body 3, the negative pressure source 30 including a motor and an impeller, the impeller rotating under the driving of the motor, thereby generating a suction airflow to suck up excrement, and the negative pressure source 30 may be a vacuum pump or the like.

[0020] The air supply line 4 includes an N-shaped pipe 40, which is located within the main body 3 and communicates with the air cushion 200 (the N-shaped pipe 40 communicates indirectly with the air cushion 200 via an air pipe). The air pump 31, air pressure sensor 320, pressure relief valve 321, and safety valve 322 are each connected to the air supply line 4 via the N-shaped pipe 40, achieving efficient and convenient connections. The N-shaped pipe 40 has a first end 400, a second end 401, and a third end 402 that pass through each other. The air pump 31 is connected to the first end 400, the air pressure sensor 320 is connected to the second end 401, and the pressure relief valve 321 is connected to the third end 402.

The adapter 41 is connected to the fourth end 403, one of the safety valves 322 is connected to the fifth end 404, and another of the safety valves 322 is connected to the sixth end 405.

[0021] The air supply line 4 further includes a check valve 45, which is connected between the first end 400 and the air pump 31 and allows the air pump 31 to one-way exhaust air to the air cushion 200. It is difficult for the air pump 31 itself to completely prevent air leakage, and the presence of the check valve 45 prevents the gas in the air cushion 200 from flowing back to the air pump 31 via the air supply line 4 after the air pump 31 stops inflating, thereby avoiding leakage. To facilitate connection, the air pump 31 and the check valve 45 are connected via a first pipe section 490, and the check valve 45 and the first end 400 are connected via a second pipe section 491. Thus, the air pump 31 is indirectly connected to the first end 400 via the first pipe section 490, the check valve 45, and the second pipe section 491, respectively. The air pressure sensor 320, the pressure relief valve 321, one of the safety valves 322, and the other of the safety valves 322 are connected to the second end 401, the third end 402, the fifth end 404, and the sixth end 405 via corresponding pipe sections (492, 493, 494, and 495), respectively.

[0034] The at least one control chip includes a main control chip 140 and a second control chip 142, and the first control chip 141 and the second control chip 142 are electrically connected to the main control chip 140, and the first control chip 141 and the second control chip 142 can receive control commands from the main control chip 140 and output control commands to the main control chip 140. In a normal state, the air pressure in the air supply line 4 is the same as the air pressure in the air cushion 200, and the air pressure sensor 320 monitors the air pressure in the air supply line 4 to indirectly monitor the air pressure in the air cushion 200. The pressure relief valve 321 is used to indirectly depressurize the air cushion 200 by depressurizing the air supply line 4. During the process of air pump 31 inflating, the time it takes for the air pump 31 to complete one intake and exhaust cycle is defined as a first cycle, and the at least one control chip (e.g., the first control chip 141) is set with a second cycle. During the process of air pump 31 inflating, the air pressure sensor 320 can monitor and obtain multiple air pressure monitoring values ​​during each second cycle, and the at least one control chip (e.g., the first control chip 141) uses the minimum value of all the air pressure monitoring values ​​monitored and obtained by the air pressure sensor 320 during the second cycle as the air pressure value of the air cushion 200 during the second cycle, and the second cycle is not shorter than the first cycle. During the inflation process of the air pump 31, it takes time for the gas to propagate from the air pump 31 to the air cushion 200. At the moment when the air is released from the air pump 31, the gas has not yet propagated sufficiently from the air pump 31 to the air cushion 200. Therefore, at the moment when the air pump 31 exhausts air (at this time, the air pressure in the air supply line 4 is particularly unstable), the air pressure value in the air supply line 4 measured by the air pressure sensor 320 cannot effectively reflect the air pressure in the air cushion 200. By setting the minimum value of all the air pressure values ​​monitored by the air pressure sensor 320 within the corresponding second period as the air pressure value of the air cushion 200 within the corresponding second period, the distorted air pressure value measured at the moment when the air pump 31 exhausts air can be filtered out. Furthermore, during the inflation process of the air pump 31, the true air pressure of the air cushion 200 within the corresponding second period can be more accurately reflected, and the air pressure of the air cushion 200 can be more accurately monitored during the inflation process of the air pump 31.The first period reflects the inflation frequency of the air pump 31. Assuming that the inflation frequency of the air pump 31 is n times per second, the first period is 1 / nth of a second. The inflation frequency of the air pump 31 is n times per second, which means that the air pump 31 completes n intakes and exhausts per second. With the maturity of air pump 31 technology, the inflation frequency of the current air pump 31 is so fast that it can easily reach several thousand times per second. During the inflation process of the air pump 31, the air pressure sensor 320 monitors the air pressure of the air supply line 4 in real time. Therefore, during each second period, the air pressure sensor 320 can monitor and obtain multiple air pressure monitoring values, and the at least one The at least one control chip (e.g., the first control chip 141) selects the second period based on the above rule (i.e., adopts the minimum value among all the air pressure monitoring values ​​within the second period). In this embodiment, the second period may be selected to be longer, for example, the second period is three times longer than the first period. When the air pressure value adopted by the at least one control chip (e.g., the first control chip 141) reaches a predetermined value, the at least one control chip (e.g., the first control chip 141) can control the air pump 31 to stop inflating, and the air pump 31 can be a diaphragm pump.

[0035] During the inflation process of the air pump 31, when the air pressure in the air supply line 4 reaches a first predetermined value (or the air pressure monitored by the air pressure sensor 320 reaches the first predetermined value), the air pump 31 stops inflating under the control of the at least one control chip (e.g., the first control chip 141); when the air pressure in the air supply line 4 drops to a second predetermined value (or the air pressure monitored by the air pressure sensor 320 drops to the second predetermined value), the air pump 31 restarts inflating under the control of the at least one control chip (e.g., the first control chip 141); and when the air pressure in the air supply line 4 reaches the first predetermined value, the air pump 31 stops, thereby dynamically maintaining the air pressure of the air cushion 200 within a predetermined air pressure range (from the second predetermined value to the first predetermined value) and realizing a relatively constant pressure of the air cushion 200. The present application does not improve the air pressure sensor 320 itself, and the air pressure sensor 320 can be selected from conventional products, and the air pressure sensor 320 continuously outputs the monitored air pressure value in real time for use by the at least one control chip (e.g., the first control chip 141). In this embodiment, when the air pressure value adopted by the at least one control chip (e.g., the first control chip 141) during the inflation process of the air pump 31 reaches a first predetermined value, it is regarded as the air pressure in the air supply line 4 reaching the first predetermined value, and the air pressure in the air cushion 200 reaching the first predetermined value. After the air pump 31 stops inflating, the air pressures in the air supply line 4 and the air cushion 200 are both very stable. In this case, the air pressure value monitored in real time by the air pressure sensor 320 can be matched with the actual air pressure values ​​in the air supply line 4 and the air cushion 200. Therefore, after the air pump 31 stops inflating, when the air pressure sensor 320 monitors in real time that the air pressure value in the air supply line 4 reaches a second predetermined value, it is regarded as the air pressure in the air supply line 4 decreasing to the second predetermined value, and the air pressure in the air cushion 200 decreasing to the second predetermined value.This nursing care machine can provide multiple inflation pressure ranges for users to select. For example, the first predetermined value is selected as 10.5KPa and the second predetermined value is selected as 9.5KPa, so that the first inflation pressure range is 9.5KPa~10.5KPa; in another case, the first predetermined value is selected as 8.5KPa and the second predetermined value is selected as 7.5KPa, so that the second inflation pressure range is 7.5KPa~8.5KPa.

[0036] The care machine further includes a touch display 150, which can be used to control the air pump 31 and / or the pressure relief valve 321. The touch display 150 is electrically connected to the main control chip 140, and the main control chip 140 can send corresponding commands to the first control chip 141 based on the commands input through the touch display 150, so that the first control chip 141 can control the air pump 31 and / or the pressure relief valve 321. In this embodiment, the touch display 150 belongs to part of the main body 3, and is disposed on the top wall of the housing 34 of the main body 3. The care machine further includes a remote control 151, which can be used to control the air pump 31 and / or the pressure relief valve 321.

The care machine has a first operation mode and a second operation mode. In the first operation mode, the negative pressure source 30 performs suction under the control of the at least one control chip (for example, the third control chip 143) to generate a negative pressure (relative to normal atmospheric pressure) in the toilet bowl 220, and the air flows into the toilet bowl 220 of the excrement collector 21 through the blower 351, the heater 350, and the drying pipe 7, thereby achieving the effect of replenishing air in the toilet bowl 220, which is beneficial to the sufficient suction of the excrement collected by the toilet bowl 220. Therefore, the drying pipe 7 is used as an air replenishing pipe. The suction of the negative pressure source 30 generates negative pressure in the toilet bowl 220, causing air to flow into the excrement collector 21 via the blower 351, the heater 350, and the drying duct 7.
