It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] like Figure 1 FIG. 1 is a schematic diagram of a roof water tank provided by an embodiment of the utility model. The roof water tank can be fixed to a roof luggage rack of a car and used as a car auxiliary accessory. For example, when traveling outdoors, the water stored in the roof water tank can be used for showering or washing the vehicle. It should be noted that the roof water tank can be manufactured, sold and used separately.

[0030] The roof water tank of the utility model includes a water tank body 10 and a booster pump 21. The water tank body 10 can be processed by rotational molding, and the water tank body 10 includes a water storage chamber, a booster pump groove 11, a water inlet and a first water outlet. Among them, the water storage chamber is a relatively sealed cavity with a certain volume, which is used to store water. The water inlet and the first water outlet are respectively connected to the water storage chamber, the booster pump groove 11 is independent of the water storage chamber, and its volume is adapted to the volume of the booster pump 21, and the first water outlet is located in the booster pump groove 11. It can be understood that in order to facilitate the filling of the water storage chamber with water, the water inlet can be located at the top of the water tank body 10, and a detachable sealing cover 12 is provided at the water inlet. When filling the water storage chamber with water, the sealing cover at the water inlet can be opened first, and the sealing cover 12 can be used to seal the water inlet after the water filling is completed.

[0031] The booster pump 21 is installed in the booster pump tank 11, and the water inlet end of the booster pump 21 is sealed and connected to the water storage chamber through the first water outlet. The water outlet end of the booster pump 21 has a first connector 22 for connecting the water device 30, that is, the water in the water storage chamber flows into the booster pump 21 through the first water outlet, and after being pressurized by the booster pump 21, it flows into the water device 30 through the first interface 22, thereby meeting the water pressure requirements of the water device 30, such as showering or washing a car. The above-mentioned first interface 22 may specifically include a valve for controlling the interruption of water flow. The shape and structure of the booster pump 21 can adopt the conventional technology in this field, which will not be repeated here.

[0032] The height of the water tank body 10 (i.e., the vertical dimension after being installed on the roof rack) is smaller than the width of the water tank body 10 (e.g., the height of the water tank body 10 may be less than 20 cm), that is, the water tank body 10 is flat as a whole, and the water tank body 10 includes a plurality of mounting holes 161 (e.g., Figure 4 As shown in FIG. 1 , the plurality of mounting holes 161 respectively penetrate the top and bottom surfaces of the water tank body 10 , and the first locking assembly 60 passes through the mounting holes 161 to lock and fix the water tank body 10 to the roof rack.
