[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 to Figure 6 A small household care machine with a simple structure comprises a housing 1, a sewage tank 2, a negative pressure device 3, an air purification device 4, a first water pump 5 and a second water pump 6. The sewage tank 2 is arranged outside the housing 1 and is detachably connected to the housing 1. A water tank 7 is arranged in the housing 1. The air purification device 4 is arranged in the housing 1 and is connected to the negative pressure device 3 and the sewage tank 2. The negative pressure device 3 is arranged in the housing 1 and is connected to the sewage tank 2. The first water pump 5 and the second water pump 6 are both arranged in the housing 1 and are connected to the water tank 7. A water inlet 11 and a water outlet 12 are arranged on the housing 1. 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. The first water pump 5 and the second water pump 6 are both located above the water tank 7. An exhaust hole 15 is arranged on the side wall of the housing 1. The exhaust hole 15 is located below the water tank 1. The air purification device 4 is connected to the exhaust hole 15.

[0032] When a small household care machine with a simple structure of the present invention is used, the negative pressure device 3 can be used to connect an external toilet collection tank, a toilet bowl, etc., so that the dirt in the toilet bowl is sucked into the sewage bucket 2 under the action of the negative pressure device 3, and the sewage and dirt are collected by the sewage bucket 2. The water in the water tank 7 can be pumped out through the water outlet 12 by the second water pump 6, and the water outlet 12 can be connected to the external toilet bowl, a shower head, etc., so as to facilitate the cleaning of the toilet area and the toilet bowl of the patient who uses the toilet, or to facilitate pumping to the shower head for the patient to bathe. When water needs to be added to the water tank 7, the corresponding water from the outside is pumped into the water tank 7 by the first water pump 5. When dirt is collected in the sewage bucket 2, the exhaust gas is purified by the air purification device 4, which has a certain purification effect on the exhaust gas, and is finally discharged through the exhaust hole 15.

[0033] In order to facilitate the connection between the water inlet 11 and the water outlet 12 and the external water pipe, a water pipe short circuit is fixed at the water inlet 11 and the water outlet 12, so as to facilitate the connection and installation with the external water pipe through the corresponding water pipe short circuit. In actual use, the sewage bucket 2 is threadedly matched with the box body 1. Therefore, when the sewage bucket 2 needs to be taken out from the box body 1, the sewage bucket 2 can be rotated and separated from the box body 1 by twisting the sewage bucket 2; conversely, when the sewage bucket 2 needs to be installed on the box body 1 for use, the sewage bucket 2 is rotated in the opposite direction so that the sewage bucket 2 is fixed on the box body 1. In actual use, in order to facilitate the user to hold the sewage bucket 2, a handle 21 is formed on one side of the sewage bucket 2, so that the operator can hold the handle 21 and install and remove the sewage bucket 2.

[0034] The box body 1 includes a main box body 13 and an upper box body 14, the upper box body 14 is fixed above the main box body 13, the water tank 7 is located in the main box body 13, and a heating device (not shown in the figure) is arranged in the water tank 7. In order to ensure the stability of the entire box body 1 and facilitate the installation of the waste bucket 2 and the box body 1, the main box body 13 is L-shaped, so that the bottom of the main box body 13 is larger, and the water tank 13 is located in the vertical part of the main box body 13; the length of the upper box body 14 is basically consistent with the length of the main box body 13, so that when the main box body 13 and the upper box body 14 are fixed, an open groove is formed between the main box body 13 and the upper box body 14, and the waste bucket 2 is placed in the open groove, thereby saving the installation space of the waste bucket 2, thereby helping to reduce the volume of the entire small home care machine with a simple structure and reducing the requirements for the use space. At the same time, the water tank 13 is located in the vertical part of the main box body 13, and the sewage bucket 2 is located outside the vertical part of the main box body 13. Therefore, when in use, the stability of the entire nursing machine can be improved.

[0035] The heating device is a low-power heater in the prior art, which can heat the water in the water tank 7 to 40-45°C, so that the water in the water tank 7 is warm water. 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 be pumped to an external shower head for convenient bathing for the patient.

[0036] When in use, in order to prevent the water in the water tank 7 from leaking out, a sealing ring is installed at the joint between the top of the water tank 7 and the upper box body 14 to play a waterproof role.

[0037] The first water pump 5 and the second water pump 6 are both located in the upper box body 14, and the water inlet 11 and the water outlet 12 are located on the upper box body 14. The water inlet end of the first water pump 5 is connected to the water inlet 11, and the water outlet end is connected to the water tank 7. The water inlet end of the second water pump 6 is connected to the water tank 7, and the water outlet end is connected to the water outlet 12. Among them, the first water pump 5 can draw water from the outside into the water tank 7 through the water inlet 11, and the water tank 7 can store clean water; the second water pump 6 can pump out the water in the water tank 7 and pump it to the external water pipe through the water outlet 12. The water inlet 11 is connected to the first water pump 5 through a water pipe, and the water outlet 12 is connected to the second water pump 6 through a water pipe.

[0038] During installation, the first water pump 5 , the second water pump 6 and the water pipes corresponding to the water pumps are all located in the upper box body 14 , which can shorten the length of the corresponding water pipes and conveniently reduce the volume of the entire upper box body 14 .

[0039] A negative pressure chamber 141 is provided on the upper box body 14, and the negative pressure device 3 includes a negative pressure fan 31. The negative pressure fan 31 is provided in the negative pressure chamber 141, and the negative pressure chamber 141 is connected to the waste bucket 2. An inlet hole 142 is provided on the upper box body 14, and the waste bucket 2 is connected to the inlet hole 142. The inlet hole 142 is connected to an external toilet or a sewage recovery device, and the inlet hole 142 is connected to the waste bucket 2 through a connecting hose. Therefore, when the negative pressure fan 31 is working, a negative pressure is formed in the negative pressure chamber 141. Under the action of the negative pressure, the sewage and dirt in the toilet connected to the inlet hole 142 are sucked into the waste bucket 2 under the action of the negative pressure, which facilitates the suction of the dirt into the waste bucket 2. When a certain amount of dirt is collected in the waste bucket 2, the waste bucket 2 is taken out, the dirt is poured out and cleaned, and the cleaning is convenient.

[0040] An air outlet 143 is provided at the top of the negative pressure chamber 141, and the air outlet 143 is connected to the air outlet end of the negative pressure fan 31. An exhaust hole 15 is provided on one side of the main box body 13. 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 a mounting tube 41 and activated carbon 42. The mounting tube 41 is fixed in the box body 1. A U-shaped groove 71 is provided on the outer side of the water tank 7. The mounting tube 41 is located in the U-shaped groove 71 and penetrates the U-shaped groove 71. The activated carbon is located in the mounting tube 41. One end of the mounting tube 41 is connected to the air outlet 143, and the other end is connected to the exhaust hole 15. Among them, the top end of the mounting tube 41 penetrates the bottom end of the upper box body 14 and then extends into the upper box body 14. The top end of the mounting tube 41 is connected to the air outlet 143 of the negative pressure chamber 141 through a hose, so that the exhaust gas discharged from the waste container 2 flows into the mounting tube 41 through the air outlet 143; the air is purified by the activated carbon in the mounting tube 41. After the bottom end of the mounting tube 41 passes through the entire U-shaped groove 71 on the side of the water tank 7, it extends to the bottom of the water tank 7, which is beneficial to increase the length of the entire mounting tube 41. That is, on the basis of ensuring the amount of water stored in the water tank 7, the position of the mounting tube 41 is reasonably arranged, and the exhaust gas discharged from the sewage tank 2 can be purified through a longer path, that is, the exhaust gas can be fully in contact with the activated carbon 42, and the purification effect can be improved under the adsorption of the activated carbon.

[0042] When the negative pressure fan 31 is in use, a negative pressure is formed in the negative pressure chamber 141, and the negative pressure fan 31 draws the waste gas in the waste container 2 upward and discharges it outward through the air outlet 143. After the waste gas flows out through the air outlet 143, it is purified by the air purification device 4 and finally discharged through the exhaust hole 15.

[0043] The exhaust hole 15 is opened at a position near the bottom of the main box body 13, and a pipe joint is installed at the exhaust hole 15, and a connecting pipe is installed on the pipe joint, which is convenient for connecting with the bottom end of the installation pipe 41 through the pipe joint and the connecting pipe, so that the gas in the installation pipe 41 can be smoothly discharged through the exhaust hole 15. In order to facilitate the connection between the bottom end of the installation pipe 41 and the corresponding connecting pipe, a pipe joint is fixedly set at the bottom end of the installation pipe 41, which is convenient for the installation and removal of the corresponding connecting pipe.

[0044] When installing the air purification device 4, the activated carbon is bagged through a mesh bag or a cloth bag so that the length of the bag after bagging is consistent with the length of the installation tube 41, and the outer diameter is basically consistent with the inner diameter of the installation tube 41, so that the activated carbon after bagging can be stuffed into the installation tube 41. When the activated carbon is installed, the bottom end of the installation tube 41 is connected to the exhaust hole 15 through the connecting pipe. When the activated carbon needs to be replaced after being used for a period of time, the connecting pipe connected to the bottom end of the installation tube 41 is rotated and loosened, and then the whole bag of activated carbon in the installation tube 41 is extracted, and then the new activated carbon is reloaded into the installation tube 41, which is convenient for the installation and removal and replacement of the activated carbon.

[0045] In order to further facilitate the installation of the activated carbon in the installation tube 41, a bottom cover is fixed to the bottom of the main box body 13 by screws, and the bottom cover is locked and fixed to the main box body 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, after the waste gas in the sewage tank 2 flows to the installation pipe 41 through the air outlet 143, the waste gas is purified by the activated carbon in the installation pipe 41. Since the entire length of the installation pipe 41 is relatively large, it has a good purification effect and is finally discharged from the exhaust hole 15, so that the final discharged gas has no odor or very little odor, which greatly improves the care environment.

[0047] In actual use, in order to further improve the nursing environment, an exhaust pipe is sleeved on the outside of the exhaust hole 15, and the exhaust pipe is detachably connected to the pipe joint at the exhaust hole 15. The exhaust pipe can be extended to the outside. Specifically, when in 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 box 13 is an electric control box 131, in which a power source 8 is fixed, and the electric control box 131 is located below the water tank 7. The main box 13, the water tank 7 and the electric control box 131 are an integrated structure, and the power source 8 is electrically connected to the first water pump 5, the second water pump 6, the negative pressure fan 31 and the heating device through wires. Therefore, the position below the water tank 7 in the main box 13 is directly used as the electric control box 131, so that there is no need to add another box, which is conducive to improving the compactness of the main box 13 structure, reducing the volume of the main box 13, and thus reducing the molding cost of the main box 13; at the same time, the separation of water and electricity is achieved to meet the corresponding use requirements.

[0049] In actual use, a control circuit board can be fixedly installed in the upper box body 14, and a control switch can be installed on the outer side of the upper box body 14. The control switch is electrically connected to the control circuit board through a wire; the control switch is electrically connected to the power supply 8 through a wire through the control circuit board. The power supply 8 is electrically connected to the first water pump 5, the second water pump, the negative pressure fan 31, the heating device and other electrical components through the control circuit board, which is convenient for controlling the working state of each component and is easy to use. Among them, the control circuit board and the control switch are both prior art, that is, the corresponding components are turned on and off by connecting the switch to the control circuit board, which belongs to the prior art, and the specific control principle is not repeated here.

[0050] The power supply in the electric control box 131 can adopt a switching power supply, which can convert the 220V external mains power into 24V, which is convenient for powering on various electrical components in the box; a power socket is installed on the outside of the main box 13 to facilitate the connection between the power supply and 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 box body 13, a wire outlet hole 132 is provided at the top of the main box body 13, and a wire inlet hole 144 is provided at the top of the negative pressure cavity 141. Thus, the wires of the power supply 8 and the electric control part in the electric control box 131 can be led upward through the wiring cavity 10, through the wire outlet hole 132, and then electrically connected to the corresponding structure. Among them, there can be two wire outlet holes 132, respectively close to the opposite sides of the main box body, and the position of the wire outlet hole 132 can be adjusted accordingly according to the actual position of the first water pump 5 and the second water pump 6, so that the two wire outlet holes 132 are correspondingly close to the corresponding water pumps, which can simplify the wiring of the wires in the upper box body 14. The wires led out through the wire outlet hole 132 and connected to the negative pressure fan 31 extend into the negative pressure cavity 141 through the wire inlet hole 144 to achieve electrical connection with the negative pressure fan 31.

[0052] like Figure 2 , Figure 6 and Figure 7 As shown, a small-sized household care machine with a simple structure of the present invention also includes a mounting member 9. A through hole 145 (not shown) is provided at the bottom of the upper box body 14. The mounting member 9 includes a horizontal portion 91, a cylindrical portion 92 and a barrel portion 93. The horizontal portion 91 is provided at the top of the cylindrical portion 92. The cylindrical portion 92 is sleeved in the through hole 145 and fixed to the upper box body 14. The outer diameter of the barrel portion 93 is smaller than the inner diameter of the cylindrical portion 92. The barrel portion 93 passes through the horizontal portion 91. The negative pressure chamber 141 is located in the barrel portion 93. The negative pressure fan 31 is located in the barrel portion 93. The barrel portion 93 is connected to the sewage receiving barrel 2. The air outlet 143 of the negative pressure fan 31 is located at the top of the barrel portion 93. The mounting member 9 is an integrally formed structure. Among them, the outer diameter of the cylindrical portion 92 is consistent with the inner diameter of the through hole 145, and the outer side of the cylindrical portion 92 is further fixed to the bottom of the upper box body 14 by screws, ensuring that the mounting member 9 can be tightly fixed on the upper box body 14; the top of the cylindrical portion 92 is located inside the upper box body 14, and the bottom is located below the upper box body 14.

[0053] Since the outer diameter of the barrel portion 93 is smaller than the inner diameter of the cylindrical portion 92 , it is convenient to install other corresponding structures on the horizontal portion 91 outside the barrel portion 93 , thereby achieving effective use of space and helping to reduce the volume of the entire upper box body 14 .

[0054] A threaded hole is provided on the inner side of the cylindrical portion 92, through which the threaded hole can be threadedly matched with the waste bucket 2, so as to facilitate the installation and removal of the waste bucket 2.
