[0002] The fuel pump is an important component of the car heater. It is mainly used to draw fuel from the fuel tank and deliver it to the atomizer to provide fuel for the heater's combustion. The main motor of the car heater drives the plunger fuel pump to rotate. The fuel pump delivers the fuel drawn in to the atomizer through the fuel pipeline. In some electromagnetic fuel pumps, the armature component is attracted to move axially and reciprocally through the electromagnetic coil assembly to realize the intake and discharge of fuel.

[0003] In the existing technology, if impurities are present inside the oil pump of an integrated car heater and cannot be cleaned and collected in time, it will damage the inside of the oil pump, which will not only affect the performance of the oil pump, but also affect its service life. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing an integrated automotive heater oil pump.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An integrated automotive heater oil pump includes a pump body, a motor fixedly connected to the side wall of the pump body, an inlet and an outlet respectively opened on the side wall of the pump body, an inlet pipe fixedly connected to the side wall of the pump body at the inlet, an outlet pipe fixedly connected to the side wall of the pump body at the outlet, a rotating shaft fixedly connected to the end of the output shaft of the motor, the rotating shaft being rotatably connected to the inner wall of the pump body, multiple blades fixedly connected around the shaft wall of the rotating shaft, a connecting frame fixedly connected to the inner wall of the pump body, multiple filter screens provided on the inner wall of the connecting frame, a connecting bracket fixedly connected to the shaft wall of the rotating shaft, and a scraper fixedly connected to the end of the connecting bracket opposite to the rotating shaft.

[0006] Preferably, a plurality of connecting seats are fixedly connected around the wall of the liquid inlet pipe.

[0007] Preferably, a fixing frame is fixedly connected to the inner wall of the pump body, and the shaft wall is rotatably connected to the inner wall of the fixing frame.

[0008] Preferably, a connecting plate is fixedly connected to the bottom of the pump body, and multiple recesses are provided on the side wall of the connecting plate, with mounting bolts threaded into the interior of each of the multiple recesses.

[0009] Preferably, a plurality of brush plates are fixedly connected to the side of the scraper away from the connecting frame, and the plurality of brush plates are respectively attached to the side wall of the filter screen.

[0010] Preferably, the inner wall of the connecting frame is provided with an annular groove, and a guide slider is fixedly connected to the end of the scraper away from the connecting frame. The guide slider is slidably disposed on the inner wall of the annular groove.

[0011] Preferably, the cross-section of the guide slider is set as a trapezoidal block, and the connecting frame is located on the inner wall of the annular groove and matches the guide slider.

[0012] Compared with the prior art, the present invention provides an integrated automotive heater oil pump, which has the following advantages: 1. In this integrated automotive heater oil pump, as fuel flows through the pump body, it first passes through a connecting frame fixed to the inner wall of the pump body. Multiple filters installed on the inner wall of the connecting frame can filter impurities in the fuel, preventing impurities from entering the heater and affecting its normal operation. At the same time, the connecting bracket fixed to the shaft wall rotates synchronously with the shaft, and the scraper fixed to the end of the connecting bracket away from the shaft also rotates. Multiple brush plates fixed to the side of the scraper away from the connecting bracket are respectively attached to the side wall of the filter screen. During the rotation, the brush plates will clean the impurities attached to the surface of the filter screen, preventing impurities from clogging the filter screen and causing a decrease in fuel delivery efficiency.

[0013] 2. This integrated automotive heater oil pump starts rotating through a rotating shaft fixed to the end of the motor output shaft. The rotating shaft is rotatably connected to the inner wall of the pump body and the inner wall of the fixed bracket. The fixed bracket provides additional support for the rotating shaft to prevent shaking when the rotating shaft rotates at high speed. Multiple blades fixed around the shaft wall rotate synchronously with the rotating shaft. The centrifugal force generated by the rotation of the blades will create a negative pressure inside the pump body, causing external fuel to be drawn into the pump body through the inlet pipe. Then, the fuel flows to the outlet of the pump body under the push of the blades, and finally is delivered to the automotive heater through the outlet pipe to complete the fuel supply.

[0014] 3. When the scraper rotates, the guide slider fixed at the end away from the connecting frame slides along the annular groove opened on the inner wall of the connecting frame. The cross-section of the guide slider is set as a trapezoidal block and matches the inner wall of the annular groove. This structure can provide guidance for the rotation of the scraper, ensuring that the scraper always fits the filter screen and rotates stably, further improving the cleaning effect of the filter screen and ensuring that the oil pump delivers fuel stably for a long time.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-4 An integrated automotive heater oil pump includes a pump body 1. A motor 2 is fixedly connected to the side wall of the pump body 1. An inlet and an outlet are respectively opened on the side wall of the pump body 1. An inlet pipe 3 is fixedly connected to the side wall of the pump body 1 at the inlet, and an outlet pipe 4 is fixedly connected to the side wall of the pump body 1 at the outlet. A rotating shaft 6 is fixedly connected to the end of the output shaft of the motor 2. The rotating shaft 6 is rotatably connected to the inner wall of the pump body 1. Multiple blades 7 are fixedly connected around the shaft wall of the rotating shaft 6. A connecting frame 9 is fixedly connected to the inner wall of the pump body 1. Multiple filter screens 10 are provided on the inner wall of the connecting frame 9. A connecting bracket 13 is fixedly connected to the shaft wall of the rotating shaft 6. A scraper 14 is fixedly connected to the end of the connecting bracket 13 opposite to the rotating shaft 6.

[0019] Multiple connecting seats 5 are fixedly connected around the wall of the inlet pipe 3. A fixing frame 8 is fixedly connected to the inner wall of the pump body 1. The shaft wall of the rotating shaft 6 is rotatably connected to the inner wall of the fixing frame 8. A connecting plate 11 is fixedly connected to the bottom of the pump body 1. Multiple notches are opened on the side wall of the connecting plate 11. The interior of the multiple notches is threaded with mounting bolts 12. Multiple brush plates 15 are fixedly connected to the side of the scraper 14 away from the connecting frame 13. The multiple brush plates 15 are respectively attached to the side wall of the filter screen 10.

[0020] First, the equipment is installed and fixed. The connecting plate 11 fixed at the bottom of the pump body 1 has mounting bolts 12 with internal threads in the side wall recess, which can fix the oil pump in the designated position on the car. Multiple connecting seats 5 are fixed around the wall of the inlet pipe 3 for connecting to the external fuel delivery pipeline, ensuring that the inlet end is tightly connected and not prone to leakage, thus preparing for fuel delivery.

[0021] After the motor 2 is started, the rotating shaft 6 fixed at the end of the output shaft of the motor 2 begins to rotate. The rotating shaft 6 is rotatably connected to the inner wall of the pump body 1 and the inner wall of the fixed bracket 8 fixed to the inner wall of the pump body 1. The fixed bracket 8 can provide additional support for the rotating shaft 6 to prevent shaking when the rotating shaft 6 rotates at high speed. Multiple blades 7 fixed around the shaft wall of the rotating shaft 6 rotate synchronously with the rotating shaft 6. The centrifugal force generated by the rotation of the blades 7 will form a negative pressure inside the pump body 1, which will draw external fuel into the pump body 1 through the inlet pipe 3. Then, the fuel flows to the outlet of the pump body 1 under the push of the blades 7, and finally is delivered to the car heater through the outlet pipe 4 to complete the fuel supply.

[0022] During the flow of fuel within the pump body 1, it first passes through the connecting frame 9 fixed to the inner wall of the pump body 1. Multiple filters 10 provided on the inner wall of the connecting frame 9 can filter impurities in the fuel, preventing impurities from entering the heater and affecting its normal operation. At the same time, the connecting bracket 13 fixed to the shaft wall of the rotating shaft 6 rotates synchronously with the rotating shaft 6. The scraper 14 fixed to the end of the connecting bracket 13 away from the rotating shaft 6 also rotates accordingly. Multiple brush plates 15 fixed to the side of the scraper 14 away from the connecting bracket 13 are respectively attached to the side wall of the filter 10. During the rotation, the brush plates 15 will clean the impurities attached to the surface of the filter 10, preventing impurities from clogging the filter 10 and causing a decrease in fuel delivery efficiency.

[0023] To ensure that the scraper 14 always keeps in contact with the filter screen 10 and rotates stably, such as Figure 1-4 As shown, the inner wall of the connecting frame 9 is provided with an annular groove. The end of the scraper 14 away from the connecting frame 13 is fixedly connected to a guide slider 16. The guide slider 16 is slidably disposed on the inner wall of the annular groove. The cross-section of the guide slider 16 is set as a trapezoidal block. The connecting frame 9 is located on the inner wall of the annular groove and matches the guide slider 16.

[0024] When the scraper 14 rotates, the guide slider 16 fixed at the end opposite to the connecting frame 13 will slide along the annular groove opened on the inner wall of the connecting frame 9. The cross-section of the guide slider 16 is set as a trapezoidal block and matches the inner wall of the annular groove. This structure can provide guidance for the rotation of the scraper 14, ensuring that the scraper 14 always fits the filter screen 10 and rotates stably, further improving the cleaning effect of the filter screen 10 and ensuring that the oil pump delivers fuel stably for a long time.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
