[0043] Further explanation, as shown in FIG. 1, FIG. 3 and FIG. 4, the working base 200 has a stand 201 and a set of bases 202 arranged at the bottom of the stand 201 and extending toward the front side of the stand 201. The stand 201 has a receiving space 203 with an opening facing forward for the rear part of the self-propelled device 100 to dock. The working base 200 is also provided with a signal transmitting unit 204, a water replenishing module 205, a charging module 206 and a control circuit board 207. The control circuit board 207 is electrically connected to the signal transmitting unit 204, the water replenishing module 205 and the charging module 206.

[0044] The charging module 206 is connected to the external wire 211, including a pair of charging contacts 208 arranged on the base 202, and the rear portion 102 of the self-propelled device 100 is correspondingly provided with a pair of electrode contacts 105, so that when the self-propelled device 100 is docked on the working base 200, the electrode contacts 105 establish an electrical connection with the charging contacts 208, so that the charging module 206 supplies power to the battery module 5 through the charging contacts 208 and the electrode contacts 105.

[0045] The water replenishment module 205 is connected to an external water pipe 212 and has a water outlet 209 in the receiving space 203 for connecting to the interface 103 connected to the water tank 2 to replenish water to the water tank 2. A switch valve 210 is provided in the water outlet 209 to control whether water is added or not, and the switch valve 210 is controlled by the control circuit board 207.

[0046] The signal transmitting unit 204 is preferably disposed at the front side of the stand 201, and the signal receiving unit 6 is disposed at the rear side of the front portion 101 of the self-propelled device 100 and is flush with the height of the signal transmitting unit 204. The signal transmitting unit 204 sends a guiding signal, which is received by the signal receiving unit 6, so that the control unit 7 confirms the position of the working base 200 according to the guiding signal and quickly guides the self-propelled device 100 to return to the working base 200 and dock.

[0047] In some preferred embodiments, the signal receiving unit 6 is an infrared signal receiver. The signal transmitting unit 204 includes a centering signal transmitter (not shown), a first signal transmitter (not shown) and a second signal transmitter (not shown), and the centering signal transmitter, the first signal transmitter and the second signal transmitter are all infrared transmitters. The left guide signal emitted by the first signal transmitter is a long-range infrared signal, which is used to project on the left front area in front of the working base 200, the right guide signal emitted by the second signal transmitter is a long-range infrared signal, which is used to project on the right front area in front of the working base 200, and the centering guide signal emitted by the centering signal transmitter is a short-range infrared signal, which is used to project on the area directly in front of the working base.

[0048] When the self-propelled device 100 appears in the above-mentioned left front area or right front area, the relative position of the self-propelled device 100 and the working base 200 can be determined according to the received left guide signal or right guide signal, and then the self-propelled device 100 is guided to move toward the front area to search for the centering guide signal. Then, under the guidance of the centering guide signal, the self-propelled device 100 accurately aligns its rear part 102 with the receiving space 203 and docks on the working base 200, so that the interface part 103 is connected to the water outlet part 209, and the electrode contact 105 is connected to the charging contact 208.

[0049] Please refer to FIG. 5 , the control unit 7 further has a low-power judgment mechanism and a low-water level judgment mechanism. The low-power judgment mechanism is that when the power of the battery module 5 is lower than a power setting value, the control unit 7 activates the recharge mode. The low-water level judgment mechanism is that a water level sensing unit 21 is set in the water tank 2. The water level sensing unit 21 senses the water level in the water tank and outputs a water level value. When the control unit 7 determines that the water level value is lower than a water level setting value, the recharge mode is activated.

[0050] In the recharge mode, please refer to Figures 2 to 5. The control unit 7 searches for the guide signal sent by the signal transmitting unit through the signal receiving unit 6, so that the control unit 7 can control the self-propelled device 100 to move and dock in the working base 200 according to the guide signal, and make the charging contact 208 of the charging module 206 and the electrode contact 105 of the battery module 5 dock with each other to charge the battery module. The water outlet 209 of the water replenishment module 205 docks with the interface 103 connected to the water tank 2. The control unit 7 is also electrically connected to a wireless transmission unit 8, and the wireless transmission unit 8 transmits the water level value to the control circuit board 207. The control circuit board 207 controls the time for the switch valve 210 to open and inject water according to the water level value. The wireless transmission unit 8 can also be used to receive a control signal from an external mobile device, so that the control unit 7 has the function of being remotely activated, which is convenient for users to remotely control the self-propelled device to sprinkle water on vegetation.

[0051] Based on the above, the intelligent automatic sprinkler device provided by the present invention can achieve the following improvement effects:
