In some embodiments, the number of guide surfaces 221 and fittings 230 is the same. For example, when the number of the guide surfaces 221 is 2, the number of the fitting members 230 is also 2; for example, when the number of the guide surfaces 221 is 3, the number of the fitting members 230 is also 3, and so on, which is not listed here. One guide surface 221 and one assembly member 230 form a guide positioning group, each guide positioning group corresponds to one mounting member 30, in this embodiment, the box body 210 has four corners, each corner is provided with one guide positioning group, four mounting members 30 are arranged in the mounting space 10 of the rack 100, and four mounting members 30 correspond to the four guide positioning groups.

In some embodiments, as shown in fig. 7, since the first planes 335 of the installation parts 33 are perpendicular to each other two by two, the guide surfaces 221 are perpendicular to each other two by two, and the first plane 335 of each installation part 33 corresponds to the corresponding guide surface 221, the acting force of the installation part 30 on the liquid supply tank 200 is more balanced in each direction of the liquid supply tank 200. Referring to fig. 4, in some embodiments, if the guide surfaces 221 are not perpendicular to each other two by two, and the first planes 335 of the mounting portions 33 are not perpendicular to each other two by two, the acting force of the mounting member 30 on the liquid supply tank 200 is not uniform in all directions of the liquid supply tank 200, which may cause the liquid supply tank 200 to shift or skew. For example, the biasing force of the mounting tool 30 on the liquid supply tank 200 is large in the a1 direction and the a2 direction of the liquid supply tank 200, and small in the B1 direction and the B2 direction of the liquid supply tank 200, and the liquid supply tank 200 is likely to shift or tilt in the B1 direction or the B2 direction.

In some embodiments, referring to fig. 3 and 7, the first plane 335 of the mounting portion 33 forms an angle α of 45 ° with the second plane 50 of the fixed mounting member 30 on the rack 100, and accordingly, the angle β between at least one of the plurality of guiding surfaces 221 and at least one of the non-guiding surfaces 240 is 135 °. In this way, the force applied by the mounting member 30 to the liquid supply tank 200 can be concentrated at the center of the liquid supply tank 200, so that the liquid supply tank 200 is uniformly applied with force in each direction, and the liquid supply tank 200 is further prevented from being deviated or inclined.

Referring to fig. 2 and 3, the guide member 220 and the guide portion 31 may directly guide the liquid supply tank 200 by the cooperation of the guide wheel 311 and the guide surface 221, so that the liquid supply tank 200 may be accurately mounted at a predetermined mounting position when mounted into the mounting space 10 along the first direction X, and simultaneously, resistance received when the liquid supply tank 200 is mounted into the mounting space 10 along the first direction X or dismounted from the mounting space 10 along the second direction Y may be reduced, and the liquid supply tank 200 may be dismounted with a small force by the cooperation of the guide wheel 311 and the guide surface 221. Wherein the first direction X is opposite to the second direction Y.

In one embodiment, guide member 220 is guide surface 221, and correspondingly, guide portion 31 is guide wheel 311. When the liquid supply tank 200 is mounted into the mounting space 10 in the first direction X or dismounted from the mounting space 10 in the second direction Y, the guide surface 221 contacts the guide wheel 311 of the guide portion 31, and the guide wheel 311 can rotate to assist mounting or dismounting of the liquid supply tank 200.

Stop 250 is located at the end of guide 220. When stopper portion 250 abuts against guide portion 31, liquid supply tank 200 is fixed to chassis 100, and fitting member 230 can be tightly fitted to mounting portion 33, so that liquid supply tank 200 is stably fixed at a predetermined mounting position.

In one embodiment, the stopper 250 is a groove. The guide part 31 may be a slider, and the guide part 31 interferes with the stopper part 250 when a portion of the slider protrudes into the groove. The guide part 31 may also be a guide wheel, and the guide part 31 interferes with the stopper 250 when a portion of the guide wheel protrudes into the groove. When the guide portion 31 interferes with the stopper portion 250, the fitting 230 is tightly fitted to the mounting portion 33.

In another embodiment, stop 250 is a protrusion. The guide portion 31 may be a slider, and when the liquid supply tank 200 is moved so that the slider abuts against the protrusion, the liquid supply tank 200 cannot be moved further, and at this time, the fitting 230 is tightly fitted to the mounting portion 33. The guide portion 31 may be a guide wheel, and when the liquid supply tank 200 is moved so that the guide wheel abuts against the protrusion, the liquid supply tank 200 cannot be moved further, and at this time, the fitting 230 is tightly fitted to the mounting portion 33.

Referring to fig. 2, in some embodiments, fitting member 230 protrudes relative to guide member 220 such that mounting portion 33 can press against liquid supply tank 200 when liquid supply tank 200 is fixed to rack 100, i.e., mounting portion 33 can tightly fit with fitting member 230 to prevent liquid supply tank 200 from shifting or skewing.

Referring to fig. 3, in some embodiments, the assembly member 230 includes a first surface 231, a second surface 232, and a third surface 233 connecting the first surface 231 and the second surface 232. Referring to fig. 9, the mounting portion 33 includes a first surface 331, a second surface 332, and a third surface 333 connecting the first surface 331 and the second surface 332. When the liquid supply tank 200 is fixed on the frame 100, the first surface 231 abuts against the first surface 331, the second surface 232 abuts against the second surface 332, and the third surface 233 abuts against the third surface 333. In this manner, fitting 230 is more closely fitted to mounting portion 33.

The thickness or average thickness of the reinforcing member 270 is greater than the thickness or average thickness of other portions of the case 210, so that the case 210 has a higher strength at the position of the reinforcing member 270, and is not easily deformed or damaged.

In yet another embodiment, the stiffener 270 is a separately molded structure and is integrated with the case 210 at the second side 212 by a blow molding process. For example, the reinforcement member 270 is formed first, the case 210 and the reinforcement member 270 are molded together when the case 210 is molded by blow molding, and the case 210 molded by blow molding and the reinforcement member 270 are integrated. Wherein the stiffener 270 is integrated with the case 210 at the second side 212 of the case 210, and a portion of the stiffener 270 is located at the second side 212 and a portion is located at the third side 213 and where the second side 212 meets the third side 213.

In yet another embodiment, the stiffener 270 is a separate molded structure and is mounted to the second side 212 of the case 210, such as by being non-removably attached to the second side 212 of the case 210 by gluing, welding, or the like; or removably attached to the second side 212 of the housing 210 by a threaded arrangement, a hinged arrangement, a snap-fit arrangement, or the like. A portion of the reinforcing member 270 covers the second side 212, and another portion covers the third side 213 and a portion where the second side 212 and the third side 213 meet.

In some embodiments, the stiffener 270 includes a first stiffener 271 and a second stiffener 272. The first reinforced part 271 is located on the second side 212, the second reinforced part 272 is located on the third side 213, and the second side 212 and the third side 213 are connected.

Wherein, the thicknesses of the first reinforced part 271 and the second reinforced part 272 are the same; or the first reinforced part 271 is thicker than the second reinforced part 272; further alternatively, the second reinforced part 272 is thicker than the first reinforced part 271.

Referring to FIG. 10, in some embodiments, the supply tank 200 may further include a plurality of tank feet 280. Each box leg 280 is mounted on the second side 212, and the box legs 280 are used for supporting the box 210, so as to further protect four corners of the box 210 from being directly contacted with a bearing surface (e.g., the ground) to cause wear, damage and water leakage over time, and the like.

In some embodiments, the bin foot 280 includes a coupler 281 and a support 282. The first end 2811 of the coupler 281 is connected with the second side 212. The support 282 is connected to a second end 2812 of the coupler 281. The supporting member 282 has a cavity 2821 therein, and the end of the supporting member 282 away from the connector 281 has a through hole 2822, and the cavity 2821 is communicated with the through hole 2822. The through hole 2822 serves to discharge fluid entering the cavity 2821 from the connection of the support 282 and the coupler 281. The through hole 2822 may be smaller in size, and the through hole 2822 may be recessed in the plane where the through hole 2822 is located, so that when the liquid supply tank 200 is placed on a non-solid plane (such as a field or a mud land), soil or other ground dirt is not easily taken away, so as to prevent dirt from being stored in the cavity 2821.

In some embodiments, each bin foot 280 is mounted to a respective stiffener 270 on each second side 212. Specifically, the first reinforcement portion 271 is coupled to the first end 2811 of the coupler 281 such that the tank foot 280 is mounted on the reinforcement member 270. The first reinforcing part 271 and the engaging part 281 may be non-detachably connected by gluing, welding, ultrasonic crimping, etc., or detachably connected by a screw structure, a hinge structure, a snap structure, etc.

Referring to fig. 11, in some embodiments, the fluid supply tank 200 may further include a filter cartridge 290, a first end 292 of the filter cartridge 290 is installed inside the tank 210 and located at the water outlet 214 of the tank 210, a second end 293 of the filter cartridge 290 is a free end, and the filter cartridge 290 is used for filtering the fluid contained in the tank 210.

Specifically, the filter cartridge 290 is used to filter solid impurities and prevent the solid impurities from clogging the water outlet 214. In one embodiment, the filter cartridges 290 are provided with filter screens 291, which can be configured with different mesh sizes for the filter cartridges 290 to meet different filtering requirements. For example, the filter screen 291 with smaller mesh and larger pore size is configured to mainly filter larger solid impurities; or a filter screen 291 with a larger mesh and a smaller pore size is provided to filter smaller solid impurities.

Referring to fig. 12, in some embodiments, the first central axis OO1 of the filter cartridge 290 along the length direction is inclined and forms an angle θ (30 °, 74.5 °) with respect to the second central axis OO2 of the housing 210 along the height direction (which is the same as the X direction shown in fig. 2), and the angle θ can be any value between 30 ° and 74.5 °, for example, the angle θ is 30.5 °, 31.6 °, 33.9 °, 36.4 °, 39.1 °, 40 °, 42.5 °, 45 °, 47.3 °, 50.4 °, 52.2 °, 56.9 °, 58.4 °, 60 °, 61.6 °, 63.7, 65.4 °, 67.7 °, 70.5 °, 72.1 °, 74.5 °, etc., which are not listed here.

When the first central axis OO1 of the filter cartridge 290 in the longitudinal direction is not inclined (the angle θ is 0 °) with respect to the second central axis OO2 of the housing 210 in the height direction, as shown in fig. 12(b), the impurities filtered by the filter cartridge 290 are easily accumulated on the bottom of the filter cartridge 290, and the filter screen 291 is clogged. When the liquid level in liquid supply tank 200 falls below the blocked portion of filter screen 291, filter screen 291 does not perform a filtering function. Referring to fig. 12(a), compared to the arrangement of the filter cartridge 290 shown in fig. 12(b), in the embodiment shown in fig. 12(a), the first central axis OO1 of the filter cartridge 290 along the length direction is inclined and forms an included angle with respect to the second central axis OO2 of the box 210 along the height direction, when the liquid level in the box 210 is lowered below the filter cartridge 290, the portion of the filter cartridge 290 shown in fig. 12(a) that is submerged in the liquid is more than the portion of the filter cartridge 290 shown in fig. 12(b), that is, a larger area of the filter screen 291 participates in the filtering operation, the effective operation area of the filter cartridge 290 can be increased, and since the filter screen 291 with a larger area participates in the filtering operation, the time for the filter screen 291 to be completely blocked can be delayed, the filtering effect is better, and the spraying effect of the unmanned aerial vehicle 1000 is better.
