In an embodiment, the pump body 210 is provided with a new water connection channel 216, one end of the new water connection channel 216 penetrates through the cavity wall of the spool cavity 211, and the other end of the new water connection channel 216 is communicated with the new water pipeline 700; the valve body 231 has a third valve body position in which the valve body passage group communicates with the new water connection passage 216 and the scooping connection passage 213, and the pump power mechanism 220 is configured to generate fluid delivery power that causes fluid to flow from the scooping connection passage 213 to the new water connection passage 216.

With the above structure, the valve element channel group of the valve element 231 selectively communicates with two channels to be communicated by utilizing the position change of the valve element 231, so that the corresponding function of the pump assembly 200 is switched, and the structure is simple and easy to implement.

In an embodiment, the pump power mechanism 220 includes a piston 221, an elastic member 222 and an operating member 223, the pump body 210 is provided with a piston cavity, the piston 221 is movably disposed in the piston cavity, a variable volume cavity 224 is formed by enclosing an end surface of the piston 221 and a cavity wall of the piston cavity, the operating member 223 is movably disposed in the pump body 210, the operating member 223 is used for driving the piston 221 to move in the piston cavity to compress the volume of the variable volume cavity 224, and the elastic member 222 is used for providing an elastic restoring force for restoring the piston 221; the watering can further comprises a first one-way valve 801, a second one-way valve 802, a third one-way valve 803 and a fourth one-way valve 804, the first one-way valve 801 being for defining a fluid flow unidirectionally from the water drawing line 400 to the cartridge channel group, the second one-way valve 802 being for defining a fluid flow unidirectionally from the water drawing line 500 to the cartridge channel group, the third one-way valve 803 being for defining a fluid flow unidirectionally from the cartridge channel group to the water discharge line 600, the fourth one-way valve 804 being for defining a fluid flow unidirectionally from the cartridge channel group to the fresh water line 700; in the first valve core position, the variable volume chamber 224 communicates with the ejection passage 212 and the water drawing connection passage 213 through the valve core passage group; in the second spool position, the variable volume chamber 224 communicates with the water pumping connection passage 214 and the water discharging connection passage 215 through the spool passage group; in the third spool position, the variable volume chamber 224 communicates with the fresh water connection passage 216 and the scooping connection passage 213 through the spool passage group.

Referring to fig. 4, when the valve body 231 is at the first valve body position and the pump assembly 200 is in the first fluid delivery state, the piston 221 is pushed by the operating member 223 to compress the variable volume chamber 224, and then the operating member 223 is released to reset the piston 221 by the elastic member 222, so that the volume of the variable volume chamber 224 is increased; the above process is repeated such that the volume of the variable volume chamber 224 alternately becomes larger and smaller. When the volume of the volume-variable cavity 224 is increased, a relative negative pressure is formed in the volume-variable cavity 224, and water in the water storage cavity 110 of the watering can flows into the volume-variable cavity 224 through the water drawing pipeline 400, the water drawing connecting channel 213 and the valve core channel group; when the volume of the variable volume chamber 224 becomes smaller, a relatively high pressure is formed, and as the path of the fluid backflow is blocked by the first check valve 801, the fluid in the variable volume chamber 224 is pressed toward the ejection passage 212 and finally ejected through the ejection port of the ejection head 300, thereby completing the function of the watering can spray.

Referring to fig. 5, the valve spool 231 is in the second spool position and the pump assembly 200 is in the second fluid delivery state, in which the volume of the variable volume chamber 224 is alternately increased and decreased, again by the operating member 223. When the volume of the volume-variable cavity 224 is increased, a relative negative pressure is formed in the volume-variable cavity 224, and water to be extracted in the plant water bottle enters the volume-variable cavity 224 through the water pumping pipeline 500, the water pumping connecting channel 214 and the valve core channel group, so that water pumping is realized; when the volume of the variable volume chamber 224 becomes smaller, a relatively high pressure is formed, and the fluid in the variable volume chamber 224 is not returned to the water pumping line 500 due to the second check valve 802, but is discharged through the water discharge connection passage 215 and the water discharge line 600, thereby realizing the discharge of the extracted water. Wherein, due to the third check valve 803, when the volume of the variable volume chamber 224 becomes large, the water discharged from the water discharge line 600 is not sucked back into the variable volume chamber 224.

Referring to fig. 6, the valve spool 231 is in the third spool position and the pump assembly 200 is in the third fluid delivery state, at which time the volume of the variable volume chamber 224 is alternately increased and decreased, also by the operating member 223. When the volume of the volume-variable cavity 224 is increased, a relative negative pressure is formed in the volume-variable cavity 224, and water in the water storage cavity 110 of the watering can flows into the volume-variable cavity 224 through the water drawing pipeline 400, the water drawing connecting channel 213 and the valve core channel group; when the volume of the variable volume chamber 224 becomes smaller, a relatively high pressure is formed, in which water does not flow back to the water drawing line 400 due to the first check valve 801, but is outputted to the outside through the new water connection passage 216 and the new water line 700, thereby completing the new water filling. In the structure shown in fig. 6, although the spool passage group communicates with the water pumping connection passage 214, the water is not flowed to the water pumping line 500 through the water pumping connection passage 214 even when the volume of the variable volume chamber 224 is reduced due to the provision of the second check valve 802.

In an embodiment, the valve element 231 is rotatably disposed in the spool chamber 211, and the valve element 231 switches the first, second, and third spool positions by rotation. The valve core channel group comprises a central channel 2311 and a plurality of radial channels 2312, wherein the inner ends of the radial channels 2312 are communicated with the central channel 2311, and the outer ends of the radial channels 2312 are provided with butt joints on the peripheral surface of the valve core 231; when the valve core 231 rotates to the first valve core position, the interfaces of the three radial channels 2312 are respectively opposite to and mutually communicated with one end of the spraying channel 212, one end of the water drawing connecting channel 213 and one end of the variable volume cavity 224, so that the functions of communicating the spraying channel 212, the water drawing connecting channel 213 and the variable volume cavity 224 by the valve core channel group are realized; when the valve core 231 rotates to the second valve core position, the butt joints of the three radial channels 2312 are respectively opposite to and mutually communicated with one end of the water pumping connection channel 214, one end of the water discharging connection channel 215 and one end of the variable volume cavity 224, so that the functions of communicating the water pumping connection channel 214, the water discharging connection channel 215 and the variable volume cavity 224 by the valve core channel group are realized; when the valve element 231 rotates to the third valve element position, the butt joints of the three radial channels 2312 are respectively opposite to and mutually communicated with one end of the new water connection channel 216, one end of the water drawing connection channel 213 and one end of the variable volume cavity 224, so that the function of communicating the new water connection channel 216, the water drawing connection channel 213 and the variable volume cavity 224 by the valve element channel group is realized. The above structure utilizes the rotation of the valve core 231 to make the central channel 2311 and the radial channel 2312 on the valve core communicate with the two channels to be communicated and the variable volume cavity 224, and has smart design, simple structure and easy implementation.

It is envisioned that in other embodiments, the valve element 231 may be shifted in position instead of being rotated, for example, by axially moving, and the valve element channel group specifically includes a plurality of axially arranged through channels extending through the valve element 231, and when the valve element 231 axially moves, two channels to be communicated and the variable volume chamber 224 are communicated through different through channels. After the valve element 231 moves axially to change the position, the position can be positioned by a spring ball or a spring pin so as to avoid random actions. In an embodiment, for sealing, a non-setting sealant may be disposed between the valve element 231 and the spool chamber 211 to reduce the possibility of water leakage, or the surface layer of the valve element 231 may be an elastic layer, for example, a silica gel layer or a rubber layer, and the elastic layer is used to press the chamber wall of the spool chamber 211 to realize sealing.

In an embodiment, part of the radial channels 2312 in the valve core channel group may have multiple communication functions according to different valve core positions, that is, the same radial channel 2312 may be used to communicate with different channels at different valve core positions, so that the number of radial channels 2312 may be reduced, and the structure may be simplified. In the embodiment, the number of the radial passages 2312 is four, but the number thereof may be appropriately configured according to actual circumstances.

In an embodiment, the first check valve 801 includes a ball, one end of the water drawing pipeline 400 is provided with a flaring portion, the ball is accommodated in the flaring portion, when water flows from the water storage cavity 110 to the water drawing connecting channel 213, the ball can be flushed by water flow, and the water flow flows to the water drawing connecting channel 213 through the flaring portion, so that the ball cannot block the water flow; if the water flow reversely flows from the water drawing connection channel 213 to the water drawing pipeline 400, the ball seals the communication port between the expansion port and the main body channel of the water drawing pipeline 400 under the action of the water pressure, thereby blocking the water flow from flowing back and realizing the function of the one-way valve. In an embodiment, the second check valve 802, the third check valve 803, and the fourth check valve 804 are similar in structure, each including a diaphragm and a mesh portion disposed in a corresponding connection channel.
