The oil pump assembly 500 also includes a gear, and the gear of the oil pump assembly 500 is drivingly connected to the output gear 210.

[0046] In the embodiment of the present invention, a through hole 120 penetrating the outer shell 100 is provided at the bottom of the outer shell 100, and a plurality of first connecting columns 111 are arranged at intervals around the circumference of the through hole 120. Figure 2 As shown, a threaded hole is provided on the top of the first connecting column 111, the first connecting column 111 is integrally formed with the outer shell 100, and a plurality of reinforcing ribs are also provided on the outer side wall of the first connecting column 111.

Preferably, the diameters of the first connecting column 111, the second connecting column, and the third connecting column are successively reduced, and the corresponding bolts corresponding to the first connecting column 111, the second connecting column, and the third connecting column also have size differences. The outer shell 100, the reduction box structure 200, the protective shell 300, and the assembly structure 400 are all connected by fasteners, which is mature and reliable, and can effectively reduce production costs. At the same time, they can be disassembled and assembled without the help of more tools, which reduces maintenance costs.

[0048] In the embodiment of the present utility model, a battery box 450 is installed in the battery compartment 420, and the battery box 450 is detachably connected to the battery compartment 420; Figure 3 As shown, the battery compartment 420 of the small oil filling mechanism in this embodiment is connected to the battery box 450 by means of an elastic sheet, but the present application does not specifically limit the connection method between the battery compartment 420 and the battery box 450, and the specific detachable connection method can be selected according to actual conditions. The battery box 450 is used to install batteries, and the batteries in the battery box 450 can be replaced individually, or the battery box 450 can be replaced as a whole.

[0049] In the embodiments of the present invention, referring to Figure 1 As shown, the battery compartment 420 is arc-shaped, so the battery box 450 is also arc-shaped, and the arc angle of the battery compartment 420 is 120 degrees to 180 degrees. Designing the battery compartment 420 to be arc-shaped can better adapt to the shape of the outer shell 100, thereby making fuller use of the internal space of the accommodating cavity 110.

[0050] In the embodiments of the present invention, referring to Figures 3 to 5 As shown, an elastic structure 440 is installed at the bottom of the battery compartment 420, and the elastic structure 440 is against the battery box 450. The elastic structure 440 is used to apply force to the battery box 450 to make it separate from the battery compartment 420, so that when the battery box 450 is replaced, after the battery box 450 is separated from the battery compartment 420, the battery box 450 can pop out a certain distance under the action of the elastic structure 440 to facilitate the removal of the battery box 450.

[0051] Specifically, refer to Figures 3 to 5 As shown, in the embodiment of the utility model, the bottom of the battery compartment 420 is provided with a bottom hole 430 penetrating the battery compartment 420, the side wall of the bottom hole 430 is provided with a first limiting structure 431 extending toward the center, the battery compartment 420 is provided with a second limiting structure 432 extending toward the center direction of the bottom hole 430, and the elastic structure 440 includes a circular plate 441, and the circular plate 441 is clamped between the first limiting structure 431 and the second limiting structure 432. The elastic structure 440 also includes a conical spring 442, and the conical spring 442 includes a large head end and a small head end, and the large head end is connected to the circular plate 441; the two ends of the conical spring 442 are respectively against the circular plate 441 and the battery box 450. The elastic structure 440 is arranged in the bottom hole 430, so that the elastic structure 440 can exert force on the battery box 450, and the battery compartment 420 can also communicate with the accommodating cavity 110 through the bottom hole 430, thereby reducing the risk of water vapor generated in the battery compartment 420, and also facilitating the heat dissipation of the battery compartment 420, reducing the damage of high temperature to the battery life. The circular plate 441 and the conical spring 442 can be connected by welding or using a plug rod.

[0052] Further, in the embodiments of the present invention, referring to Figure 4 As shown, the first limiting structure 431 is basically consistent with the second limiting structure 432, and the first limiting structure 431 and the second limiting structure 432 are spaced apart in the vertical direction; the first limiting structure 431 is composed of three spaced apart first limiting blocks, and the three first limiting blocks are evenly spaced around the circumference, and the second limiting structure 432 is composed of three spaced apart second limiting blocks, and the three second limiting blocks are evenly spaced around the circumference; the three first limiting blocks and the three second limiting blocks are staggered, so as to facilitate the installation of the circular plate 441.

[0053] In the embodiment of the present invention, the diameter of the circular plate 441 is substantially consistent with the inner diameter of the bottom hole 430 , and the inner circle size of the first limiting structure 431 and the inner circle size of the second limiting structure 432 are both smaller than the diameter of the circular plate 441 .

[0054] In the embodiments of the present invention, referring to Figure 3As shown, the battery compartment 420 is provided with two bottom holes 430, the two bottom holes 430 are arranged at intervals around the circumference, and elastic structures 440 are installed in the two bottom holes 430; Figure 2 As shown, the bottom of the accommodating cavity 110 is provided with a first supporting column 112, referring to Figure 1 As shown, the reduction box structure 200 is provided with a second support column 220, and the first support column 112 and the second support column 220 are respectively against the circular plates 441 of the two elastic structures 440. Specifically, the first support column 112 and the second support column 220 have basically the same structure and basically the same size. The diameters of the first support column 112 and the second support column 220 are basically the same as the inner circle size of the second limiting structure 432. The first support column 112 is arranged on the outer shell 100, and the second support column 220 is arranged on the reduction box structure 200 in order to better arrange the positions of the first support column 112 structure and the second support column 220 structure. Figure 1 , Figure 2 It can be seen that if the second support column 220 is also set to be connected to the outer shell 100, the second support column 220 will interfere with a first connection column 111, so the second support column 220 is set on the reduction box structure 200. The first support column 112 and the second support column 220 can also support the circular plate 441, reducing the risk of deformation of the circular plate 441; at the same time, since the battery box 450 itself also has a certain weight, the first support column 112 and the second support column 220 can also indirectly support the battery box 450, avoiding deformation and damage of the assembly structure 400 under long-term uneven stress.

At the same time, since the automatic oiling machine includes the small oiling mechanism mentioned above, it has at least all the beneficial effects of the small oiling mechanism, which will not be elaborated here.
