Description

Technical Field

[0001] This utility model relates to a nursing robot, and more particularly to a small home nursing machine with a simple structure. Background Technology

[0002] For bedridden patients, standing, sitting, and turning over are inconvenient, as are getting up to use the toilet and bathe. Therefore, patients often need to use the toilet and bathe in bed. Many nursing robots have emerged to collect waste from a patient's wearable toilet bowl, clean the bowl with fresh water, and then collect the wastewater. For example, application number 202120357770.7 discloses a toilet flushing and drying device for a nursing robot. As shown in its instructions and drawings, the entire main unit has a complex structure. It uses a motor to extract excrement and includes various connecting valves and other structures, resulting in a large overall size and high manufacturing cost, leading to a high market price and hindering its widespread use in homes. Furthermore, the large size of the main unit's injection-molded casing requires highly sophisticated molds, significantly increasing the overall cost. Additionally, when using this type of nursing robot, the patient's excrement is directly emitted, which can cause discomfort to caregivers; and the wastewater discharge mechanism from the wastewater tank is complex and inconvenient to operate. Utility Model Content

[0003] The purpose of this invention is to provide a simple, small home care machine that can solve at least one of the above problems.

[0004] According to one aspect of this utility model, a small home care machine with a simple structure is provided, including a housing, a waste collection bin, a negative pressure device, an air purification device, a first water pump, and a second water pump. The waste collection bin is located on the outside of the housing and is detachably connected to the housing. A water tank is provided inside the housing. The air purification device is located inside the housing and is connected to the negative pressure device and the waste collection bin. The negative pressure device is located inside the housing and is connected to the waste collection bin. The first water pump and the second water pump are both located inside the housing and are both connected to the water tank. The housing is provided with an inlet and an outlet. The first water pump is connected to the inlet, and the second water pump is connected to the outlet.

[0005] The beneficial effects of this utility model are as follows: The waste collection bin is located on the outside of the housing and is detachably connected to it, thus facilitating its fixation and removal. When waste needs to be cleaned, the bin can be simply removed from the housing, simplifying cleaning and significantly reducing the overall structure. A water tank is directly installed inside the housing; a second water pump draws water from the tank to power an external toilet bowl and / or shower head, facilitating cleaning of the patient's toilet bowl or bathing the patient. A negative pressure device allows for the creation of negative pressure within the waste collection bin, drawing waste from the external toilet bowl into it. An air purification device purifies the exhaust gas inside the waste collection bin, largely preventing its emission and significantly improving the nursing environment. Therefore, the overall structure of the housing is greatly simplified, its volume significantly reduced, and production costs significantly lowered, making it suitable for widespread use in households.

[0006] In some embodiments, the enclosure includes a main enclosure and an upper enclosure, with the upper enclosure fixed above the main enclosure. The water tank is located inside the main enclosure and contains a heating device. This facilitates the separate processing and molding of the main enclosure and the upper enclosure, thereby reducing the processing difficulty of the enclosure, lowering the requirements for production molds, and helping to reduce production costs. The heating device allows for heating of the water in the tank, bringing it to a warm temperature for easier patient rinsing and improving user comfort.

[0007] In some embodiments, both the first and second water pumps are located inside the upper tank, with their inlets and outlets situated on the upper tank. The inlet of the first water pump is connected to the inlet, and its outlet is connected to the water tank. Similarly, the inlet of the second water pump is connected to the water tank, and its outlet is connected to the outlet. Thus, through the installation and connection of these pumps, water in the water tank is pumped out by the second water pump, while the first water pump supplies water to the water tank.

[0008] In some embodiments, the upper housing is provided with a negative pressure chamber, and the negative pressure device includes a negative pressure fan located inside the negative pressure chamber. The negative pressure chamber is connected to the sludge collection tank, and the upper housing is provided with an inlet hole, which is connected to the sludge collection tank. Thus, the negative pressure fan creates negative pressure within the negative pressure chamber, thereby creating corresponding negative pressure within the sludge collection tank. Through this negative pressure, sludge connected to the inlet hole can be drawn into the sludge collection tank for collection, simplifying the sludge suction structure.

[0009] In some embodiments, the top of the negative pressure chamber is provided with an air outlet, which is connected to the air outlet of the negative pressure fan. The side wall of the main housing is provided with an exhaust hole. One end of the air purification device is connected to the air outlet, and the other end is connected to the exhaust hole. Thus, the air outlet facilitates the discharge of exhaust gas through the air outlet and its purification by the purification device.

[0010] In some embodiments, the air purification device includes an installation pipe and activated carbon. The installation pipe is fixed inside the housing, and a U-shaped groove is provided on the outside of the water tank. The installation pipe is located inside and passes through the U-shaped groove, and the activated carbon is located inside the installation pipe. One end of the installation pipe is connected to the air outlet, and the other end is connected to the exhaust port. Therefore, by providing an installation pipe, the installation of activated carbon can be conveniently facilitated; at the same time, the activated carbon inside the installation pipe can be easily extracted and replaced.

[0011] In some embodiments, the bottom of the main housing is an electrical control box, which houses a power supply. The electrical control box is located below the water tank, and the main housing, water tank, and electrical control box are integrally formed. The power supply is electrically connected to the first water pump, the second water pump, and the negative pressure fan via wires. Thus, having the electrical control box at the bottom of the main housing separates it from the water tank, facilitating the installation of the power supply and other structures, resulting in a more rational structural distribution within the main housing, and reducing its overall volume.

[0012] In some embodiments, a wiring cavity is formed between the outer wall of the water tank and the inner wall of the main tank. The top of the main tank has a cable outlet, and the top of the negative pressure cavity has a cable inlet. This facilitates the connection of wires inside the main tank to the corresponding structures inside the upper tank via the cable inlet, simplifying the wiring process.

[0013] In some embodiments, a simple small home care machine also includes a mounting component. The bottom of the upper housing has a through hole. The mounting component includes a horizontal section, a cylindrical section, and a cylindrical section. The horizontal section is located at the top of the cylindrical section, which is fitted into the through hole and fixed to the upper housing. The outer diameter of the cylindrical section is smaller than the inner diameter of the cylindrical section, and the cylindrical section penetrates the horizontal section. A negative pressure chamber is located inside the cylindrical section, and a negative pressure fan is located inside the cylindrical section. The cylindrical section is connected to a waste collection tank, and the air outlet of the negative pressure fan is located at the top of the cylindrical section. The mounting component is a one-piece molded structure. Therefore, the mounting component facilitates the installation of the negative pressure fan and the connection between the negative pressure chamber and the waste collection tank.

[0014] In some embodiments, a simple, small home care machine also includes a plasma generator, which is fixed to the bottom of a horizontal section and can be located inside a waste collection tank. The horizontal section has a connecting hole through which the waste collection tank communicates with a feed inlet. Therefore, by incorporating a plasma generator, preliminary purification of exhaust gases can be conveniently achieved, resulting in a certain purification effect.

[0015] The main beneficial effects of this utility model are:

[0016] 1. The sludge collection bucket is detachably connected to the box body, which makes it easy to fix and remove the sludge collection bucket from the box body. Therefore, when the sludge in the sludge collection bucket needs to be cleaned, the sludge collection bucket can be directly removed from the box body, which facilitates the cleaning and washing of the sludge in the sludge collection bucket, greatly simplifies the overall structure, makes it easy for the operator to operate manually, and the simple overall structure helps to reduce the overall production cost.

[0017] 2. The main body, water tank, and electrical control box are integrally molded, which facilitates the processing and molding of the main body and achieves the separation of the water tank and electrical control box, thus realizing the separation of water and electricity. The various structures inside the main body are rationally distributed, which greatly reduces the volume of the main body, thereby reducing the requirements for the molding mold of the main body, greatly reducing the volume of the corresponding mold, greatly reducing the processing cost of the main body, and thus reducing the overall cost.

[0018] 3. Equipped with a purification device and a plasma generator, the waste gas in the waste collection tank undergoes preliminary purification under the action of ions generated by the plasma generator; then, the waste gas is further purified by the purification device, and the activated carbon can purify the air, so that the final exhaust gas has very little odor, greatly improving the nursing environment.

[0019] 4. The installation pipe runs through the U-shaped groove on the side of the water tank, facilitating the outflow of exhaust gas and significantly increasing the path of exhaust gas discharge. This allows the exhaust gas to fully interact with the activated carbon inside the installation pipe, increasing the adsorption time between the exhaust gas and the activated carbon and improving the air purification effect. At the same time, the distribution of the installation pipe increases the exhaust gas flow path without increasing the volume of the main body, achieving a reasonable structural distribution and making the overall structure very compact, which helps to reduce the volume of the main body.

[0020] 5. The upper housing facilitates the installation and fixing of each water pump, as well as the distribution and connection of the corresponding inlet and outlet holes, simplifying the path of the corresponding water pipes and thus reducing the overall volume of the upper housing. At the same time, it facilitates the outlet of the negative pressure chamber, making it easy to connect with the installation pipe and achieve air purification and discharge.

[0021] 6. The entire structure of this small home care machine is simple and compact. Through the reasonable distribution of each structure, the volume of the entire box is greatly reduced. The overall volume can be reduced by two-thirds compared with the existing conventional care robots. The simple structure makes it easy to promote and use in the home, and its application range is wider.

[0022] 7. By installing a heating device inside the water tank, the water in the tank can be heated to make the water warm. This ensures that the water pumped by the second water pump to the outlet is warm, which is more effective in rinsing the patient's toilet area and improving the comfort of use.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Reference Figures 1-6 A simple small home care machine includes a housing 1, a waste collection tank 2, a negative pressure device 3, an air purification device 4, a first water pump 5, and a second water pump 6. The waste collection tank 2 is located on the outside of the housing 1 and is detachably connected to the housing 1. A water tank 7 is located inside the housing 1. The air purification device 4 is located inside the housing 1 and is connected to the negative pressure device 3 and the waste collection tank 2. The negative pressure device 3 is located inside the housing 1 and is connected to the waste collection tank 2. The first water pump 5 and the second water pump 6 are both located inside the housing 1 and are both connected to the water tank 7. The housing 1 has a water inlet 11 and a water outlet 12. The first water pump 5 is connected to the water inlet 11, and the second water pump 6 is connected to the water outlet 12.

[0032] This utility model discloses a simple, small-scale home care machine. In use, a negative pressure device 3 connects to an external toilet bowl and waste collection container, allowing waste in the waste collection container to be drawn into a waste collection tank 2 under the pressure of the negative pressure device 3. The waste collection tank 2 collects the waste. A second water pump 6 pumps water from the water tank 7 through the outlet 12, which can be connected to an external waste collection container or shower head for easy cleaning of the patient's toilet area and waste collection container, or for convenient showering. When water needs to be added to the water tank 7, the first water pump 5 draws water from outside into the water tank 7. When the waste collection tank 2 contains waste, the exhaust gas is purified by an air purification device 4 before being discharged through the exhaust port 15.

[0033] To facilitate the connection of the inlet 11 and outlet 12 to external water pipes, water pipe short connectors are fixed at the inlet 11 and outlet 12, allowing for easy connection and installation with external water pipes. In actual use, the waste collection bin 2 is threaded onto the housing 1. Therefore, when the waste collection bin 2 needs to be removed from the housing 1, it can be rotated to separate it from the housing 1; conversely, when the waste collection bin 2 needs to be installed on the housing 1, it can be rotated in the opposite direction to secure it to the housing 1. To facilitate the user's grip on the waste collection bin 2, a handle 21 is formed on one side of the bin 2, allowing for easy installation and removal.

[0034] The housing 1 includes a main housing 13 and an upper housing 14. The upper housing 14 is fixed above the main housing 13, and the water tank 7 is located inside the main housing 13. The water tank 7 is equipped with a heating device (not shown in the figure). To ensure the stability of the entire housing 1 and to facilitate the installation of the waste collection bucket 2 with the housing 1, the main housing 13 is L-shaped, resulting in a larger bottom. The water tank 13 is located in the vertical part of the main housing 13. The length of the upper housing 14 is basically the same as the length of the main housing 13. Therefore, after the main housing 13 and the upper housing 14 are fixed, an opening groove is formed between the main housing 13 and the upper housing 14. The waste collection bucket 2 is placed in this opening groove, thereby saving the installation space of the waste collection bucket 2. This helps to reduce the overall size of the simple small home care machine and lowers the space requirements. Meanwhile, the water tank 13 is located inside the vertical part of the main body 13, and the sludge bin 2 is located outside the vertical part of the main body 13. Therefore, the stability of the entire nursing machine can be improved during use.

[0035] The heating device is a low-power heater found in existing technology, which can heat the water in the water tank 7 to 40-45℃, making the water in the water tank 7 warm. Therefore, the second water pump 6 can pump the warm water in the water tank 7 to the patient's toilet area for cleaning; it can also pump it to an external shower head for the patient to take a shower.

[0036] During use, in order to prevent water from leaking out of the water tank 7, a sealing ring is installed at the joint between the top of the water tank 7 and the upper tank body 14 to serve as a waterproofing element.

[0037] The first water pump 5 and the second water pump 6 are both located inside the upper housing 14. The inlet 11 and outlet 12 are located on the upper housing 14. The inlet of the first water pump 5 is connected to the inlet 11, and its outlet is connected to the water tank 7. The inlet of the second water pump 6 is connected to the water tank 7, and its outlet is connected to the outlet 12. The first water pump 5 draws water from the outside and pumps it into the water tank 7 through the inlet 11, where the water tank 7 stores clean water. The second water pump 6 pumps water from the water tank 7 and pumps it to an external water pipe through the outlet 12. The inlet 11 is connected to the first water pump 5 via a water pipe, and the outlet 12 is connected to the second water pump 6 via a water pipe.

[0038] During installation, the first water pump 5, the second water pump 6, and the water pipes connected to the water pumps are all located inside the upper housing 14, which can shorten the length of the corresponding water pipes and facilitate the reduction of the overall volume of the upper housing 14.

[0039] The upper housing 14 is equipped with a negative pressure chamber 141. The negative pressure device 3 includes a negative pressure fan 31, which is located inside the negative pressure chamber 141. The negative pressure chamber 141 is connected to the sludge collection tank 2. The upper housing 14 is equipped with an inlet hole 142, which is connected to the sludge collection tank 2. The inlet hole 142 is connected to an external waste collection container or a sewage recovery device, and is connected to the sludge collection tank 2 via a connecting hose. Thus, when the negative pressure fan 31 operates, a negative pressure is created inside the negative pressure chamber 141. Under the action of the negative pressure, sewage and waste in the waste collection container connected to the inlet hole 142 are sucked into the sludge collection tank 2, facilitating the collection of waste into the sludge collection tank 2. When a certain amount has been collected in the sludge collection tank 2, the sludge collection tank 2 can be removed, the waste poured out, and the tank cleaned, making cleaning convenient.

[0040] The top of the negative pressure chamber 141 is provided with an air outlet 143, which is connected to the air outlet of the negative pressure fan 31. The main housing 13 is provided with an exhaust hole 15 on one side. One end of the air purification device 4 is connected to the air outlet 143, and the other end is connected to the exhaust hole 15.

[0041] The air purification device 4 includes an installation pipe 41 and activated carbon 42. The installation pipe 41 is fixed inside the housing 1. A U-shaped groove 71 is provided on the outside of the water tank 7. The installation pipe 41 is located in and passes through the U-shaped groove 71. The activated carbon is located inside the installation pipe 41. One end of the installation pipe 41 is connected to the air outlet 143, and the other end is connected to the exhaust port 15. The top end of the installation pipe 41 passes through the bottom end of the upper housing 14 and extends into the upper housing 14. The top end of the installation pipe 41 is connected to the air outlet 143 of the negative pressure chamber 141 through a flexible hose, so that the exhaust gas discharged from the sludge tank 2 can flow through the air outlet 143 into the installation pipe 41; the activated carbon in the installation pipe 41 purifies the air. The bottom end of the installation pipe 41 passes through the U-shaped groove 71 on the side of the entire water tank 7 and extends to the bottom of the water tank 7. This increases the length of the entire installation pipe 41. While ensuring the water storage capacity in the water tank 7, the installation pipe 41 is positioned reasonably, allowing the exhaust gas discharged from the waste tank 2 to undergo purification through a longer path. This allows the exhaust gas to fully contact the activated carbon 42, improving the purification effect under the adsorption of the activated carbon.

[0042] When in use, the negative pressure fan 31 creates a negative pressure in the negative pressure chamber 141, drawing the waste gas in the waste collection tank 2 upwards and discharging it outwards through the air outlet 143. After flowing out through the air outlet 143, the waste gas is purified by the air purification device 4 and finally discharged through the exhaust port 15.

[0043] The vent 15 is located near the bottom of the main housing 13. A pipe fitting is installed at the vent 15, and a connecting pipe is installed on the pipe fitting to facilitate connection with the bottom end of the mounting pipe 41, allowing gas inside the mounting pipe 41 to be smoothly discharged through the vent 15. To facilitate connection between the bottom end of the mounting pipe 41 and the corresponding connecting pipe, a pipe fitting is fitted and fixed to the bottom end of the mounting pipe 41, facilitating the installation and removal of the corresponding connecting pipe.

[0044] During installation, the activated carbon is placed in a mesh or cloth bag, ensuring the bag's length matches the length of the installation tube 41 and its outer diameter is roughly the same as the inner diameter of the tube. This facilitates the insertion of the bagged activated carbon into the installation tube 41. After installation, the bottom of the installation tube 41 is connected to the exhaust port 15 via a connecting pipe. When the activated carbon needs replacement after a period of use, the connecting pipe at the bottom of the installation tube 41 is loosened by rotating it. The entire bag of activated carbon is then removed from the installation tube 41, and new activated carbon is refilled. This process simplifies the installation, removal, and replacement of the activated carbon.

[0045] To further facilitate the installation of activated carbon in the installation tube 41, a bottom cover is fixed to the bottom of the main housing 13 by screws. The bottom cover is locked to the main housing 13 by screws. When the activated carbon needs to be installed or replaced, the bottom cover can be opened by loosening the corresponding screws, which facilitates the corresponding operation of the installation tube 41.

[0046] Therefore, the waste gas in the waste collection tank 2 flows through the air outlet 143 to the installation pipe 41, where it is purified by the activated carbon. Since the installation pipe 41 is quite long, it has a good purification effect. Finally, it is discharged through the exhaust hole 15, so that the discharged gas has no odor or very little odor, which greatly improves the nursing environment.

[0047] In practical use, to further improve the nursing environment, an exhaust pipe is fitted on the outside of the exhaust port 15, and the exhaust pipe is detachably connected to the pipe joint at the exhaust port 15. The exhaust pipe can extend to the outside, and in specific use, the purified air with a small amount of odor can be discharged to the outside through the exhaust pipe, thereby making the indoor nursing environment better.

[0048] The bottom of the main housing 13 is the electrical control box 131, which houses the power supply 8. The electrical control box 131 is located below the water tank 7. The main housing 13, water tank 7, and electrical control box 131 are integrally formed. The power supply 8 is electrically connected to the first water pump 5, the second water pump 6, the negative pressure fan 31, and the heating device via wires. Therefore, the location below the water tank 7 in the main housing 13 is directly used as the electrical control box 131, eliminating the need for an additional housing. This improves the compactness of the main housing 13 structure, reduces its volume, and lowers the molding cost. Simultaneously, it achieves separation of water and electricity, meeting the corresponding usage requirements.

[0049] In practical use, a control circuit board can be fixedly installed inside the upper housing 14, and a control switch can be installed on the outside of the upper housing 14. The control switch is electrically connected to the control circuit board via wires; the control switch is also electrically connected to the power supply 8 via the control circuit board via wires. The power supply 8 is electrically connected to electrical components such as the first water pump 5, the second water pump, the negative pressure fan 31, and the heating device via the control circuit board, facilitating the control of the working status of each component and making it convenient to use. Both the control circuit board and the control switch are existing technologies; that is, the opening and closing of corresponding components is achieved through the connection between the switch and the control circuit board, which is existing technology. The specific control principle will not be elaborated here.

[0050] The power supply inside the electrical control box 131 can be a switching power supply, which can convert the 220V of the external mains power to 24V, making it convenient for the electrical components inside the box to be powered on; a power socket is installed on the outside of the main box 13 to facilitate the connection of the power supply to the external power supply.

[0051] A wiring cavity 10 is formed between the outer wall of the water tank 7 and the inner wall of the main body 13. The top of the main body 13 has an outlet hole 132, and the top of the negative pressure chamber 141 has an inlet hole 144. Thus, the power supply 8 and the wires of the electrical control components inside the electrical control box 131 can be led upwards through the wiring cavity 10, out through the outlet hole 132, and then electrically connected to the corresponding structures. There can be two outlet holes 132, located near opposite sides of the main body. The positions of the outlet holes 132 can be adjusted according to the actual positions of the first water pump 5 and the second water pump 6, so that the two outlet holes 132 are close to the corresponding water pumps, simplifying the wiring within the upper body 14. The wires led out through the outlet holes 132 and connected to the negative pressure fan 31 extend into the negative pressure chamber 141 through the inlet hole 144, achieving electrical connection with the negative pressure fan 31.

[0052] like Figure 2 , Figure 6 and Figure 7 As shown, the present invention provides a simple small home care machine, which also includes an installation component 9. The bottom of the upper housing 14 is provided with a through hole 145 (not shown in the figure). The installation component 9 includes a horizontal part 91, a cylindrical part 92 and a cylindrical part 93. The horizontal part 91 is located at the top of the cylindrical part 92. The cylindrical part 92 is fitted into the through hole 145 and fixed to the upper housing 14. The outer diameter of the cylindrical part 93 is smaller than the inner diameter of the cylindrical part 92. The cylindrical part 93 penetrates the horizontal part 91. The negative pressure chamber 141 is located inside the cylindrical part 93. The negative pressure fan 31 is located inside the cylindrical part 93. The cylindrical part 93 is connected to the waste collection tank 2. The air outlet 143 of the negative pressure fan 31 is located at the top of the cylindrical part 93. The installation component 9 is an integrally formed structure. The outer diameter of the cylindrical part 92 is the same as the inner diameter of the through hole 145. The outer side of the cylindrical part 92 is further fixed to the bottom of the upper box 14 by screws, ensuring that the mounting part 9 can be tightly fixed to the upper box 14. The top of the cylindrical part 92 is located inside the upper box 14, and the bottom is located below the upper box 14.

[0053] By making the outer diameter of the cylindrical part 93 smaller than the inner diameter of the cylindrical part 92, it is convenient to install other corresponding structures on the horizontal part 91 on the outside of the cylindrical part 93, thus realizing the effective use of space and helping to reduce the volume of the entire upper box 14.

[0054] A threaded hole is provided on the inner side of the cylindrical part 92, which allows for threaded engagement with the sludge collection tank 2, facilitating the installation and removal of the sludge collection tank 2. The cylindrical part 92 also facilitates the installation of the negative pressure fan 31. The bottom of the cylindrical part 92 has a hollow structure, which helps to create negative pressure inside the sludge collection tank 2. Under the action of negative pressure, waste from external structures such as toilets can be drawn into the sludge collection tank 2.

[0055] This utility model discloses a simple, small-scale home care machine, which also includes a plasma generator 20 (not shown in the figure). The plasma generator 20 is fixed at the bottom of the horizontal part 91 and can be located inside the waste collection tank 2. The horizontal part 91 is provided with a connecting hole 145, through which the waste collection tank 2 is connected to the feed hole 142. The connecting hole 145 is located on the outside of the cylindrical part 92 and is connected to the feed hole 142 via a connecting pipe. Since the plasma generator 20 is fixed at the bottom of the horizontal part 91 and located on the outside of the cylindrical part 93, the generated ions can directly act on the exhaust gas inside the waste collection tank 2 to perform preliminary purification; then, it is discharged to the air purification device 4 for further purification, ensuring that the exhaust gas containing waste is thoroughly purified.

[0056] In order to facilitate the movement of this simple small home care machine during use, wheels can be installed at the bottom of the box 1 to improve its applicability; or pull rings can be installed on the outside of the box 1 to make it easy to lift and move the entire box, making it convenient for the operator.

[0057] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
