Description

Technical Field

[0001] The present invention relates to the technical field of cleaning, and particularly to a variable-pitch automated portable mobile cleaning machine. Background Art

[0002] With the progress of technology and the improvement of people's living standards, the requirements for cleaning efficiency are getting higher and higher. In industrial production and daily life, it is often necessary to clean the surfaces of various equipment and objects, such as range hoods, etc. It is not very convenient during cleaning, and general cleaning devices often have limitations, resulting in unsatisfactory cleaning. Traditional cleaning equipment has various problems such as poor flexibility and inconvenience in carrying, which not only reduces the efficiency and quality of cleaning work, but also lacks safety. Therefore, the development and research of cleaning equipment have important practical significance and broad application prospects.

[0003] In the existing patent CN108533471A, a handheld high-pressure cleaning machine is disclosed, including: a housing, inside which there is a motor and a pump driven by the motor; the pump includes: a pump body; a water inlet and a water outlet provided on the pump body; a high-pressure chamber connected to the water inlet and the water outlet; the high-pressure chamber includes a first high-pressure chamber and a second high-pressure chamber, and the pump further includes a single plunger provided in the pump body, and the motor drives both ends of the plunger to reciprocate in the first high-pressure chamber and the second high-pressure chamber.

[0031] Embodiment 1:

[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown in the figure, a variable-pitch automated portable mobile cleaning machine of the present invention includes a support rod 1, a cross bar 2 is arranged on the support rod 1, a variable-pitch component 3 is arranged between the two cross bars 2, a slider 4 is arranged on the cross bar 2, the slider 4 slides along the cross bar 2 and the variable-pitch component 3, a pulling component 5 connected to the slider 4 is arranged on the cross bar 2, a storage component 6 communicating with a water supply system, a medicine supply system and a gas supply system is arranged on the slider 4, a differential pressure motion component 7 is arranged in the storage component 6, a jet component 8 adapted to the differential pressure motion component 7 is arranged on the storage component 6, a liquid supply component 9 is arranged on the storage component 6, an adjusting component 10 for adjusting the liquid supply component 9 is arranged in the storage component 6, a transmission component 11 is arranged between the differential pressure motion component 7 and the adjusting component 10, and a drying component 12 is arranged on the storage component 6; wherein, when supplying liquid, the differential pressure motion component 7 moves downward under the action of the liquid pressure and the gas pressure difference, forcing the liquid supply component 9 to open; when supplying gas, the differential pressure motion component 7 moves upward under the action of the pressure difference, forcing the jet component 8 to open, achieving a two-way control effect.

[0033] Working principle: The variable pitch component 3 is used to adjust the cross bar 2 to the required length, so that the water supply system, the medicine supply system and the gas supply system are connected to the storage component 6. When supplying water or liquid medicine, the valve of the liquid supply component 9 is opened. Due to the adjustment of the adjustment component 10 on the liquid supply component 9, water or liquid medicine will not be directly ejected at this time. It is necessary to gradually increase the pressure of the water supply system and the medicine supply system until the pressure on the liquid side of the differential pressure motion component 7 is higher than the pressure on the gas side of the differential pressure motion component 7, forcing the differential pressure motion component 7 to move, so that the differential pressure motion component 7 continuously blocks the jet component 8, so that the gas will not be ejected. At the same time, the movement of the differential pressure motion component 7 drives the transmission component 11 to move, and the movement of the transmission component 11 drives the adjustment component 10 to move. The adjustment component 10 adjusts the opening degree of the liquid supply component 9 to realize the liquid passage. Among them, when the pressure gradually increases, the opening degree of the liquid supply component 9 gradually increases, achieving the effect of automatic opening degree adjustment; when supplying gas, the valve of the jet component 8 is opened. Similarly, due to the blocking effect of the differential pressure motion component 7, the gas will not be directly ejected. It is necessary to gradually increase the pressure of the gas supply system until the pressure on the gas side of the differential pressure motion component 7 is higher than the pressure on the liquid side of the differential pressure motion component 7, forcing the differential pressure motion component 7 to move in the reverse direction until the differential pressure motion component 7 releases the jet component 8. When the pressure reaches, the gas will be ejected through the jet component 8 to achieve the jet effect; In summary, a variable pitch automatic portable mobile cleaning machine of the present application has the characteristics of variable pitch and convenient portability, integrates the functions of water spraying, medicine spraying and gas jetting, and makes the liquid passage and the gas passage affect each other, achieving the effect of two-way control, forcing the liquid or gas not to be directly ejected, avoiding accidental start-up, and preventing high pressure from affecting or harming the staff, improving the protection ability of the device, improving the safety performance of the device, improving the control ability of the device, thus facilitating the safe use of the staff and improving the market competitiveness of the product.

The second threaded rod 1001 threadedly penetrates through the adjusting plate 1003. The guide rod 1002 penetrates through the adjusting plate 1003. The adjusting plate 1003 is connected to the metering plate 904.

[0042] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown in the figure, a variable pitch automatic portable mobile cleaning machine of the present invention, the transmission assembly 11 includes a transmission straight rack 1101 arranged on the moving rod 703, and a transmission gear 1102 meshing with the transmission straight rack 1101 is fixedly sleeved on the second threaded rod 1001.

[0043] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown in the figure, a variable pitch automatic portable mobile cleaning machine of the present invention, the air drying assembly 12 includes an air duct 1201 arranged on the storage tank 601, a fan 1202 is installed in the air duct 1201, and a heating wire 1203 is arranged between the fan 1202 and the air outlet of the air duct 1201.

[0044] Working principle: Adjust the length of the cross bar 2 to a reasonable length according to the needs, increase the number of variable pitch blocks 302, connect the variable pitch blocks 302 together by using the first threaded rod 301, and connect the cross bar 2 and the variable pitch blocks 302 together to form an integral body, so that the water supply system, the medicine supply system and the gas supply system are communicated with the storage tank 601;

[0045] When supplying water or liquid medicine, open the valve of the liquid spraying pipe 901. Since the control plate 904 obstructs the liquid spraying pipe 901, water or liquid medicine will not be directly sprayed out. When spraying liquid is needed, gradually increase the pressure of the water supply system and the medicine supply system. Since the partition plate 602 divides the storage tank 601 into a liquid storage space 603 and a gas storage space 604, the pressure on the liquid side of the pressure receiving block 704 and the piston 705 is gradually higher than the pressure on the gas side of the pressure receiving block 704 and the piston 705, so that the pressure receiving block 704 and the piston 705 move downward, so that the pressure receiving block 704 drives the moving rod 703 to move, so that the moving rod 703 slides on the storage tank 601, and the moving rod 703 drives the baffle 702 to move in the protective cover 701. At this time, the moving spring 706 is compressed, the moving rod 703 drives the transmission straight rack 1101 to move, the transmission straight rack 1101 drives the transmission gear 1102 to rotate, the rotation of the transmission gear 1102 drives the second threaded rod 1001 to rotate, and under the action of the guide rod 1002, the second threaded rod 1001 drives the adjusting plate 1003 to move, and the adjusting plate 1003 drives the control plate 904 to move until the control hole 905 is aligned with the liquid spraying pipe 901, adjusts the opening degree of the liquid spraying pipe 901, realizes the liquid passage, and forces the liquid to be sprayed out through the liquid spraying nozzle 902. During this movement process, the pressure receiving block 704 and the piston 705 continuously block the air vent pipe 801, so that the gas will not be easily sprayed out;

[0046] Among them, when the pressure gradually increases, that is, the pressure on the liquid side of the pressure-receiving block 704 and the piston 705 is gradually higher than the pressure on the gas side of the pressure-receiving block 704 and the piston 705, the more the number of the liquid spray pipes 901 aligned with the metering holes 905, and the opening degree gradually increases, so as to achieve the effect of automatically adjusting the opening degree according to the pressures of the water supply system and the medicine supply system, and improve the ability of automatic adjustment;

[0047] When supplying gas, open the valve of the gas jet nozzle 804. Similarly, due to the blocking effect of the pressure-receiving block 704 and the piston 705, the gas will not be directly ejected. It is necessary to gradually increase the pressure of the gas supply system until the pressure on the gas side of the pressure-receiving block 704 and the piston 705 is higher than the pressure on the liquid side of the pressure-receiving block 704 and the piston 705, forcing the pressure-receiving block 704 and the piston 705 to move upward until the air pipe 801 communicates with the gas storage space 604. When the pressure reaches, the gas will be introduced into the gas jet nozzle 804 through the action of the air pipe 801, the horizontal pipe 802 and the branch air pipes 803, and the gas will be ejected through the action of the gas jet nozzle 804, so as to achieve the gas jet effect;

[0048] Since the same outlet is used when supplying water and liquid medicine, that is, a liquid spray nozzle 902 is used. After the liquid medicine supply is completed, the remaining liquid medicine needs to be discharged and water needs to be supplied again to avoid the liquid medicine being mixed with water for a long time. The liquid medicine is introduced into the liquid storage space 603 through the medicine supply pipe 606. Since the liquid storage space 603 communicates with the gas storage space 604, when the liquid medicine is drained, disconnect the medicine supply pipe 606 and connect the water supply pipe 605 to introduce water into the liquid storage space 603, and increase the pressure to the maximum limit, so that the pressure-receiving block 704 and the piston 705 move to the bottom of the gas storage space 604, making the air pipe 801 communicate with the gas storage space 604. At this time, the air pipe 801 contacts the liquid medicine. Since the pressure-receiving block 704 and the piston 705 move downward, under the blocking action of the partition plate 602, most of the liquid medicine is pushed into the gas storage space 604 to achieve the separation function. Open the gas valve and the liquid valve. Under the high pressure, the liquid medicine is ejected from the liquid spray nozzle 902 and the gas jet nozzle 804 respectively, so that the liquid medicine is ejected quickly until it is detected that the liquid medicine is drained clean, and the pressure-receiving block 704 and the piston 705 retreat to a reasonable liquid spraying position. At this time, the pressure-receiving block 704 and the piston 705 block the port of the air pipe 801, and normal water spraying can be carried out by using the liquid spray nozzle 902;

[0049] When jetting air, water or liquid medicine, start the motor 501. The output shaft of the motor 501 rotates to drive the winding rod 502 to move. The winding rod 502 drives the winding roller 503 to rotate, so that the wire rope 504 at one end is released and the wire rope 504 at the other end is wound up, causing the wire rope 504 to drive the slider 4 to move back and forth on the cross bar 2 and the variable pitch block 302, and controlling the movement speed of the slider 4, so that water, liquid medicine and gas are respectively jetted out evenly. The jetting of air, water or liquid medicine can be randomly matched to achieve the cleaning function. After the cleaning is completed and air drying is required, start the fan 1202 and heat the heating wire 1203 to increase the temperature. When the wind passes through the outlet of the air duct 1201, hot air is formed, and in cooperation with the reciprocating movement of the slider 4, the equipment is air dried.

[0050] On the one hand, this solution has the characteristics of variable pitch and convenient carrying, integrating the functions of water jetting, liquid medicine spraying and air jetting. On the other hand, it makes the liquid passage and the gas passage influence each other to achieve the effect of two-way control, forcing the liquid or gas not to be directly jetted out, avoiding accidental start-up and the influence or injury of high pressure on the staff, improving the protection ability of the device, improving the safety performance of the device, improving the control ability of the device, thus facilitating the safe use by the staff and enhancing the market competitiveness of the product. On the other hand, it can achieve the function of quickly exhausting water or liquid medicine, avoiding the long-term mixing of water and liquid medicine when switching between water supply and liquid medicine supply.

[0051] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
