Implementation

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by “upper”, “lower”, “inside”, “outside”, “top”, “bottom”, etc. are all based on the orientations or positional relationships shown in the accompanying drawings. The purpose is only to facilitate the description of the present invention and simplify the description. It does not indicate or imply that the referred parts must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0017] like Figure 1 As shown, the present invention provides a multifunctional electric filling tool vehicle with controllable flow, which specifically includes: a box body 1, an oil filling system, a liquid filling system and a power supply system; the oil filling system performs vehicle maintenance work on the oil, and a liquid filling system is provided to perform vehicle maintenance work on other liquids besides the oil. By providing the oil filling system and the liquid filling system at the same time, vehicle maintenance work can be performed on multiple liquids at the same time, thereby improving work efficiency while reducing work intensity and simplifying the operating procedures.

[0018] The bottom of the box body 1 is provided with a universal wheel 32 in front and a running wheel 35 in the back, so as to facilitate the movement of the device and improve the flexibility of the device. The oil filling system, liquid filling system and power supply system are arranged in the box body 1.

[0019] Among them, the power supply system is connected to the oil filling system and the liquid filling system respectively to provide power for them to ensure the normal operation of the device.

[0020] like Figure 1 As shown, the oil filling system includes an oil pump assembly 12, an oil filling gun 7 and an oil inlet pipe quick connector 17. The outlet and the inlet of the oil pump assembly 12 are respectively connected to the oil filling gun 7 and the oil inlet pipe quick connector 17. When the oil pump assembly 12 is started, the oil enters from the oil inlet pipe quick connector 17, is sucked by the oil pump assembly 12, and is ejected from the oil filling gun 7 to perform the oil injection work.

[0021] Among them, a flow meter 10 and a pressure gauge 19 are provided between the oil pump assembly 12 and the oil filling gun 7. During the oil filling process, the oil quality output by the oil filling system can be calculated and the pressure in the oil pipeline can be monitored at the same time, which facilitates the subsequent control of the output power of the oil pump assembly 12 and prevents excessive oil filling from causing material waste.

[0022] Furthermore, the oil pump assembly 12 is provided with a forward and reverse speed regulator 11, through which the power of the oil pump assembly 12 can be adjusted, thereby adjusting the flow rate output by the oil pump assembly 12. When the oil filling amount is about to reach the target oil filling amount, the power of the oil pump assembly 12 is reduced in conjunction with the reading of the flow meter 10, thereby further controlling the oil filling amount and saving materials.

[0023] It should be noted that the oil pump assembly 12 is connected to the oil filling gun 7 through the oil outlet hose 6, and is connected to the oil inlet pipe quick connector 17 through the oil inlet pipe 16, so that the oil filling gun 7 and the oil inlet pipe quick connector 17 can be conveniently connected to the oil barrel and the vehicle to be injected during use, thereby reducing the difficulty of operation.

[0024] In the present invention, an oil filter assembly 15 is provided on the oil inlet pipe 16 at the inlet end of the oil pump assembly 12. When the oil pump assembly 12 is started, the oil sucked from the oil inlet pipe quick connector 17 is first filtered by the oil filter assembly 15 and then injected into the maintenance vehicle through the oil pump assembly 12 through the oil filling gun 7, thereby ensuring the quality of the oil and improving work efficiency.

[0025] The outlet of the oil pump assembly 12 is provided with an oil overflow valve 30, which cooperates with the pressure gauge 19. During the operation of the oil pump assembly 12, when the oil pressure at the outlet of the oil pump assembly 12 is too high, the excess pressure and oil quality are re-introduced into the inlet of the oil pump assembly 12 by adjusting the oil overflow valve 30, which plays a role in protecting the oil circuit, preventing the oil outlet hose 6 from being damaged due to excessive oil pressure in the pipeline during use, and improving the safety and stability of the device. The oil pump assembly 12 is provided with an oil pump power switch 9 for controlling its switch.

[0026] It should be noted that the forward and reverse speed regulator 11 can adjust the direction of the oil pump assembly 12. When the oil pump assembly 12 reverses, the oil is sucked from the oil filling gun 7 and passed through the oil pump assembly 12 and then released from the oil inlet pipe quick connector 17, thereby achieving a suction effect. When the oil is replaced, the old oil can be sucked out and collected and processed in a unified manner, thereby avoiding environmental pollution caused by direct discharge of waste oil and improving the environmental protection of the device.

[0027] like Figure 1 As shown, the liquid filling system includes a liquid pump assembly 26, a liquid inlet pipe quick connector 22 and a liquid filling gun 28. The outlet and inlet of the liquid pump assembly 25 are respectively connected to the liquid filling gun 28 and the liquid inlet pipe quick connector 22. Liquid other than oil enters from the liquid inlet pipe quick connector 22 and is sucked by the oil pump assembly 25 and then ejected from the liquid filling gun 28 to perform liquid injection. In conjunction with the oil filling system, daily maintenance work such as filling two liquids can be performed at the same time.

[0028] Among them, the liquid pump assembly 26 is provided with an electronic stepless speed regulating switch 20, through which the power of the liquid pump assembly 26 can be adjusted to adjust the flow rate output by the liquid pump assembly 26, thereby controlling the filling amount of the liquid and saving materials.

[0029] Furthermore, the liquid pump assembly 26 is connected to the liquid filling gun 28 through the liquid outlet hose 27, and is connected to the liquid inlet pipe quick connector 22 through the liquid inlet hose 24, so that the filling gun 28 and the liquid inlet pipe quick connector 22 can be conveniently connected to the oil barrel and the vehicle to be injected during use, thereby reducing the difficulty of operation.

[0030] In the present invention, a liquid pump filter 25 is provided on the liquid inlet hose 24 at the inlet end of the liquid pump assembly 26. When the liquid pump assembly 26 is started, the oil sucked from the liquid inlet pipe quick connector 22 is first filtered through the liquid pump filter 25 and then injected into the maintenance vehicle through the liquid pump assembly 26 through the liquid filling gun 28, thereby ensuring the quality of the oil and improving work efficiency.

[0031] The outlet of the liquid pump assembly 26 is provided with an oil overflow valve 30. When the outlet oil pressure of the liquid pump assembly 26 is too high during the operation of the liquid pump assembly 26, the excess pressure and oil are re-introduced into the inlet of the liquid pump assembly 26 by adjusting the oil overflow valve 30, thereby protecting the oil circuit and preventing the outlet hose 27 from being damaged due to excessive oil pressure in the pipeline during use, thereby improving the safety and stability of the device. The liquid pump assembly 26 is provided with a liquid pump power switch 21 for controlling its switch.

[0032] It should be noted that the electronic stepless speed control switch 20 can adjust the direction of the liquid pump assembly 26. When the liquid pump assembly 26 reverses, the oil is sucked from the liquid filling gun 28 and passed through the liquid pump assembly 26 and then released from the liquid inlet pipe quick connector 22, thereby achieving a suction effect. When the oil is replaced, the old oil can be sucked out and collected and processed in a unified manner, thereby avoiding environmental pollution caused by direct discharge of waste oil and improving the environmental protection of the device.

[0033] like Figure 1 As shown, the power supply system includes a first battery 34 and a second battery 31 connected in series as power supplies to the system. The power supply system is provided with a battery detector 13 for monitoring the remaining power in the power supply system.

[0034] The power supply system is provided with a main power switch 14 for controlling the power supply status of the power supply system. A fuse box 23 is provided behind the main power switch 14. When an accident such as a short circuit occurs in the circuit, the fuse box 23 is activated to disconnect the circuit, thereby ensuring the integrity of various electrical components in the device and improving the safety of the device.

[0035] Furthermore, a leakage protection switch 33 is provided between the first battery 34 and the second battery 31 in the power supply system. When one of the batteries fails to work, the leakage protection switch 33 is activated to separate the two batteries.

[0036] A fuse box 23 is provided in the system working circuit, which cooperates with the leakage protection switch 33 to protect the device circuit normally. In the present invention, the box body 1 is provided with a power terminal outside and connected to the power system. The power terminal can charge the power system by connecting an external power source, and can also be connected to other vehicle batteries for temporary charging. The effect is particularly prominent during rescue work.

[0037] Among them, the power supply terminal includes a 24V positive external terminal 2, a 12V positive external terminal 3 and a negative external terminal. The power supply terminal is also provided with a 24V positive external terminal 2 and a 12V positive external terminal 3, which can charge most vehicle batteries during the rescue process, thereby improving the applicability of the device.

[0038] The outer side of the box body 1 is provided with an oil outlet pipe bracket 5, a filling gun hanger 8, an oil inlet pipe bracket 18 and a liquid hose bracket 29, which are used to place the oil outlet hose 6, the oil filling gun 7, the oil inlet pipe 16 and the liquid outlet hose 27 respectively when the device is not working. The pipes are randomly stacked to prevent them from being entangled with each other, making the device more convenient during use.

[0039] The multifunctional electric filling tool vehicle with controllable flow provided by the present invention can measure the amount of oil output by the device, control the output power of the oil pump assembly, control the filling amount, and can simultaneously replace and fill different liquids. The oil pump assembly and the liquid pump assembly can be controlled to reverse to achieve the suction effect. It is easy to move, uses electric drive throughout the process, is simple to operate, has low labor intensity, and has high accuracy and work efficiency. The specific operation process of the device is as follows: Step 1: Connect the grease gun and the oil inlet pipe quick connector to the oil filling location and the oil barrel respectively.

[0040] Step 2: Connect the liquid filling gun and the liquid inlet pipe quick connector to the place where the liquid is to be injected and the place where the liquid is stored, respectively.

[0041] Step 3: Connect the battery to be charged to the terminal outside the box according to its rated voltage.

[0042] Step 4, start the main power supply, oil pump power supply and water pump power supply. At this time, the oil pump starts to work to extract the oil in the oil barrel and inject it from the oil filling gun to the place where the oil is to be filled; the liquid pump starts to work to extract the liquid from the liquid storage place and inject it from the liquid filling gun to the place where the liquid is to be filled; the electricity in the battery charges the battery to be charged through the terminal.

[0043] Step 5: Adjust the forward and reverse speed regulator and the electronic stepless speed control switch, and adjust the flow and flow rate of the oil filling gun and the liquid filling gun to prevent the injection of excess liquid.

[0044] Step 6. After the work is completed, turn off all power supplies, and place the oil filling gun, liquid filling gun and each pipe on the corresponding bracket or hanger.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
