[0038] When the watering pot is in normal use, the pump assembly 200 is switched to the first fluid delivery state through the function switching mechanism 230, and the water in the water storage chamber 110 of the pot body 100 is delivered to the nozzle 300 through the pump assembly 200 for spraying, thereby realizing the spraying function of the watering pot. When it is necessary to change the water of the hydroponic plants, one end of the water suction port of the water suction pipeline 500 can be inserted into the bottom of the water bottle, and one end of the water discharge port of the water discharge pipeline 600 can be inserted into a container or a sink that can collect water. The pump assembly 200 is switched to the second fluid delivery state through the function switching mechanism 230, and the pump assembly 200 can suck the old water from the water bottle through the water suction pipeline 500 and release it through the water discharge pipeline 600. When the old water of the hydroponic plants is extracted, new water can be re-injected into the water bottle to complete the water change. The above-mentioned watering can has both spraying and water extraction functions, which can assist in changing water for hydroponic plants. There is no need to excessively move and manipulate the water bottle, which reduces the difficulty of changing water and enriches the original function of the watering can. In addition, the pump assembly 200 forms different fluid delivery states through the function switching mechanism 230, so that the different fluid delivery states of the pump assembly 200 can be used to realize the spraying and water extraction functions. The design is ingenious and makes full use of the fluid delivery function of the original pump assembly 200.

[0039] In the embodiment, the watering pot further includes a new water pipeline 700, one end of which is connected to the pump assembly 200, and the other end is provided with a new water outlet; the function switching mechanism 230 enables the pump assembly 200 to have a third fluid delivery state, in which the pump assembly 200 can extract the fluid in the water storage chamber 110 through the water drawing pipeline 400 and send it to the new water pipeline 700. By further configuring the new water pipeline 700 and enabling the pump assembly 200 to have the third fluid delivery state, the function of injecting new water can be added to the watering pot. After the old water of the hydroponic plants is extracted, the water drawing pipeline 500 is pulled out from the water bottle, and the new water pipeline 700 is inserted. The pump assembly 200 is switched to the third fluid delivery state through the function switching mechanism 230, and the water in the water storage chamber 110 is sucked by the pump assembly 200 and sent to the water bottle, thereby completing the function of injecting new water. The above structure enables the watering can to have the function of draining old water and adding new water, and the function is more complete, and it is more convenient to use it to change the water of hydroponic plants.
[0040] In the embodiment, the pump assembly 200 includes a pump body 210 and a pump power mechanism 220. The pump body 210 is provided with a valve core chamber 211, a spray channel 212, a water-drawing connection channel 213, a water-pumping connection channel 214 and a water-discharging connection channel 215. One end of the spray channel 212, one end of the water-drawing connection channel 213, one end of the water-pumping connection channel 214 and one end of the water-discharging connection channel 215 all pass through the cavity wall of the valve core chamber 211.

The function switching mechanism 230 includes a valve core 231, a valve core 23 1 is adapted to the valve core chamber 211, the valve core 231 is movably arranged in the valve core chamber 211 and can change its position in the valve core chamber 211, the valve core 231 is provided with a valve core channel group, and the valve core 231 has a first valve core position and a second valve core position; in the first valve core position, the valve core channel group connects the ejection channel 212 and the water drawing connection channel 213 to enable the pump assembly 200 to enter a first fluid delivery state; in the second valve core position, the valve core channel group connects the water pumping connection channel 214 and the water discharge connection channel 215 to enable the pump assembly 200 to enter a second fluid delivery state; the pump power mechanism 220 is configured to generate fluid delivery power, which can enable the fluid to flow from the water drawing connection channel 213 to the ejection channel 212, and can enable the fluid to flow from the water pumping connection channel 214 to the water discharge connection channel 215.
[0041] In an embodiment, the pump body 210 is provided with a new water connecting channel 216, one end of the new water connecting channel 216 passes through the cavity wall of the valve core cavity 211, and the other end of the new water connecting channel 216 is connected to the new water pipeline 700; the valve core 231 has a third valve core position, and in the third valve core position, the valve core channel group connects the new water connecting channel 216 and the water drawing connecting channel 213, and the pump power mechanism 220 is configured to generate a fluid conveying power that causes the fluid to flow from the water drawing connecting channel 213 to the new water connecting channel 216.
[0042] By adopting the above structure, the position of the valve core 231 is changed to make the valve core channel group of the valve core 231 selectively connect the two corresponding channels that need to be connected, thereby realizing the switching of the corresponding functions of the pump assembly 200. The structure is simple and easy to implement.
[0043] In the 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 arranged in the piston cavity, the end surface of the piston 221 and the cavity wall of the piston cavity are surrounded to form a variable volume cavity 224, the operating member 223 is movably arranged in the pump body 210, the operating member 223 is used to drive 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 to provide an elastic reset force to reset the piston 221; the spray pot also includes 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 is used to limit the fluid to flow from the water drawing pipeline 400 in one direction To the valve core channel group, the second one-way valve 802 is used to limit the fluid to flow unidirectionally from the water suction pipeline 500 to the valve core channel group, the third one-way valve 803 is used to limit the fluid to flow unidirectionally from the valve core channel group to the water discharge pipeline 600, and the fourth one-way valve 804 is used to limit the fluid to flow unidirectionally from the valve core channel group to the new water pipeline 700; in the first valve core position, the variable volume chamber 224 is connected with the ejection channel 212 and the water suction connecting channel 213 through the valve core channel group; in the second valve core position, the variable volume chamber 224 is connected with the water suction connecting channel 214 and the water discharge connecting channel 215 through the valve core channel group; in the third valve core position, the variable volume chamber 224 is connected with the new water connecting channel 216 and the water suction connecting channel 213 through the valve core channel group.
[0044] Reference Figure 4At this time, the valve core 231 is in the first valve core position and the pump assembly 200 is in the first fluid delivery state. At this time, the piston 221 is pressed by the operating member 223 to move to compress the variable volume chamber 224, and then the operating member 223 is released so that the piston 221 is reset through the elastic member 222, so that the volume of the variable volume chamber 224 increases; the above process is repeated, so that the volume of the variable volume chamber 224 alternately increases and decreases. When the volume of the variable volume chamber 224 increases, a relative negative pressure is formed in the variable volume chamber 224, and the water in the water storage chamber 110 of the spray pot flows into the variable volume chamber 224 through the water intake pipe 400, the water intake connecting channel 213 and the valve core channel group; when the volume of the variable volume chamber 224 decreases, a relatively high pressure is formed. Since the path for the fluid to flow back is blocked by the first one-way valve 801, the fluid in the variable volume chamber 224 will be pressed toward the ejection channel 212 and finally ejected through the ejection outlet of the nozzle 300, completing the spraying function of the spray pot.
[0045] Reference Figure 5 , at this time, the valve core 231 is in the second valve core position, and the pump assembly 200 is in the second fluid delivery state. At this time, the volume of the variable volume chamber 224 is alternately increased and decreased through the operating member 223. When the volume of the variable volume chamber 224 increases, a relative negative pressure is formed in the variable volume chamber 224, and the water to be extracted in the plant water bottle enters the variable volume chamber 224 through the pumping pipeline 500, the pumping connection channel 214, and the valve core channel group, thereby realizing water extraction; when the volume of the variable volume chamber 224 decreases, a relatively high pressure is formed. Due to the action of the second one-way valve 802, the fluid in the variable volume chamber 224 will not flow back to the pumping pipeline 500, but will be released through the discharge connection channel 215 and the discharge pipeline 600, thereby realizing the discharge of the extracted water. Among them, due to the function of the third one-way valve 803, when the volume of the variable volume chamber 224 increases, the water discharged from the water discharge pipeline 600 will not be sucked back into the variable volume chamber 224.
[0046] Reference Figure 6 , the valve core 231 is in the third valve core position, and the pump assembly 200 is in the third fluid delivery state. At this time, the volume of the variable volume chamber 224 is alternately increased and decreased through the operating member 223. When the volume of the variable volume chamber 224 increases, a relative negative pressure is formed in the variable volume chamber 224, and the water in the water storage chamber 110 of the spray pot flows into the variable volume chamber 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 decreases, a relatively high pressure is formed, wherein due to the action of the first one-way valve 801, the water will not flow back to the water-drawing pipeline 400, but will be output to the outside through the new water connecting channel 216 and the new water pipeline 700, thereby completing the new water infusion. In the attached Figure 6In the structure shown, although the valve core channel group is connected to the pumping connection channel 214, due to the setting of the second one-way valve 802, water will not flow to the pumping pipeline 500 through the pumping connection channel 214 when the volume of the variable volume chamber 224 becomes smaller.
[0047] In the embodiment, the valve core 231 is rotatably disposed in the valve core chamber 211, and the valve core 231 switches the first valve core position, the second valve core position and the third valve core position by rotating. The valve core channel group includes a central channel 2311 and a plurality of radial channels 2312, the inner end of the radial channel 2312 is connected to the central channel 2311, and the outer end of the radial channel 2312 is formed with a docking port on the circumferential surface of the valve core 231; when the valve core 231 is rotated to the first valve core position, the docking ports of three radial channels 2312 are respectively opposite to one end of the ejection channel 212, one end of the water-drawing connection channel 213 and one end of the variable volume chamber 224 and are connected to each other, thereby realizing the function of the valve core channel group connecting the ejection channel 212, the water-drawing connection channel 213 and the variable volume chamber 224; when the valve core 231 is rotated to the second valve core position, the docking ports of three radial channels 2312 are respectively opposite to one end of the ejection channel 212, one end of the water-drawing connection channel 213 and one end of the variable volume chamber 224 and are connected to each other. The docking ports 2312 are respectively opposite to one end of the pumping connection channel 214, one end of the drain connection channel 215 and one end of the variable volume chamber 224 and are interconnected, thereby realizing the function of the valve core channel group connecting the pumping connection channel 214, the drain connection channel 215 and the variable volume chamber 224; when the valve core 231 rotates to the third valve core position, the docking ports of the three radial channels 2312 are respectively opposite to 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 chamber 224 and are interconnected, thereby realizing the function of the valve core channel group connecting the new water connection channel 216, the water drawing connection channel 213 and the variable volume chamber 224. The above structure utilizes the rotation of the valve core 231 to make the central channel 2311 and the radial channel 2312 thereon connect the two channels that need to be connected and the variable volume chamber 224, which is ingenious in design, simple in structure and easy to implement.
[0048] It is conceivable that in other embodiments, the valve core 231 may not use a rotational method to achieve position switching, for example, it may use an axial movement method, and the valve core channel group specifically includes a plurality of axially arranged through-channels that penetrate the valve core 231. When the valve core 231 moves axially, the two channels that need to be connected and the variable volume chamber 224 are connected through different through-channels. After the valve core 231 moves axially and changes its position, the position can be positioned by a spring bead or a spring pin to prevent it from moving at will. In an embodiment, in order to seal, a non-solidifying sealant can be provided between the valve core 231 and the valve core chamber 211 to reduce the possibility of water leakage, or the surface layer of the valve core 231 can be provided as an elastic layer, and the elastic layer is, for example, a silicone layer or a rubber layer, and the elastic layer is used to squeeze the wall of the valve core chamber 211 to achieve sealing.
[0049] In the embodiment, some radial channels 2312 in the valve core channel group can have multiple connection functions according to different valve core positions, that is, at different valve core positions, the same radial channel 2312 can be used to connect different channels, thereby reducing the number of radial channels 2312 and simplifying the structure. In the embodiment, there are four radial channels 2312, but the number can also be specifically and reasonably configured according to actual conditions.
[0050] In the embodiment, the first one-way valve 801 includes a ball, and a flared portion is provided at one end of the water-drawing pipeline 400, and the ball is accommodated in the flared portion. When water flows from the water storage chamber 110 to the water-drawing connection channel 213, the water flow can flush the ball, and the water flow flows to the water-drawing connection channel 213 through the flared portion, so that the ball does not hinder the water flow; if the water flow flows in the opposite direction from the water-drawing connection channel 213 to the water-drawing pipeline 400, under the action of water pressure, the ball blocks the connecting port between the flared portion and the main channel of the water-drawing pipeline 400, thereby blocking the backflow of water flow and realizing the function of the one-way valve. In the embodiment, the second one-way valve 802, the third one-way valve 803, and the fourth one-way valve 804 have similar structures, and all include a diaphragm and a mesh portion provided in the corresponding connection channel. For the second one-way valve 802, the middle part of the diaphragm is fixed to the side of the corresponding mesh part close to the valve core 231, so that the fluid can be flushed from the outside of the diaphragm without affecting the flow. When the fluid flows from the valve core channel group of the valve core 231 to the water pumping pipeline 500, under the action of water pressure, the diaphragm will fit and seal all the mesh holes of the mesh part to form a barrier to the fluid, thus realizing the function of a one-way valve. For the third one-way valve 803 and the fourth one-way valve 804, the middle part of the diaphragm is fixed to the side of the corresponding mesh part away from the valve core 231, so that the fluid can be flushed from the inside of the diaphragm without affecting the flow. If the fluid flows back from the drain pipeline 600 and the new water pipeline 700, under the action of water pressure, the diaphragm will fit all the mesh holes of the capping mesh part, thus preventing the fluid from flowing back, thus realizing the function of a one-way valve. It is conceivable that the above-mentioned first one-way valve 801, the second one-way valve 802, the third one-way valve 803 and the fourth one-way valve 804 are not limited to the above-mentioned implementation. In this field, there are many implementations of the structure of the one-way valve, and technical personnel in this field can make specific configurations according to actual conditions.
[0051] In the embodiment, the elastic member 222 is specifically a spring, and its two ends abut against the piston 221 and the pump body 210, so as to provide an elastic reset force. Of course, it is conceivable that the elastic member 222 is not limited to being a spring, and can be, for example, a structure of a shrapnel, an elastic body, etc. In the embodiment, the operating member 223 is rotatably arranged on the pump body 210, and when the operating member 223 rotates, it presses the piston 221 to move it. Of course, it is conceivable that the operating member 223 is not limited to being rotatably arranged on the pump body 210, and can be, for example, fixed to the piston 221, so that the operating member 223 is equivalent to a button.
[0052] The pump power mechanism 220 has a simple piston power structure and is easy to implement. It is conceivable that the pump power mechanism 220 is not limited to the above-mentioned implementation. For example, the pump power mechanism 220 can also use some electric pump power mechanisms to provide power for fluid delivery.
[0053] It is conceivable that the pump assembly 200 and its function switching mechanism 230 are not limited to being implemented in the above-mentioned manner. For example, the pump assembly 200 is centered on an electric pump, and the function switching mechanism 230 is specifically a solenoid valve group connected to the electric pump. The solenoid valve group is used to switch the fluid delivery direction of the electric pump, thereby realizing the switching of the corresponding function.
[0054] In the embodiment, the kettle body 100 is provided with an old water tank 120, and the other end of the drain pipe 600 is arranged in the cavity of the old water tank 120. With the above structure, the old water discharged by the drain pipe 600 can be collected by the old water tank 120, so that no additional container is required, which is convenient for actual use.
[0055] In an embodiment, the old water tank 120 is provided with a pouring opening 121 , so that the stored old water can be easily drained through the pouring opening 121 .
[0056] In the embodiment, the drain pipe 600 is a flexible pipe, and the other end of the drain pipe 600 can be moved out of the old water tank 120; the pumping pipe 500, the drain pipe 600 and the new water pipe 700 are flexible pipes, so it is convenient to choose whether to use an external water receiving container or the old water tank 120 for water collection. In addition, the use of a flexible pipe setting can facilitate the placement of the pipe when the spray pot is used.
[0057] In the embodiment, the spray pot further comprises a shell part 900, the shell part 900 is arranged on the pump assembly 200, the function switching mechanism 230 is provided with a switching operation part 232, the switching operation part 232 is exposed relative to the shell part 900, the switching operation part 232 drives the function switching mechanism 230 to switch the fluid delivery state of the pump assembly 200 by changing its position, and the shell part 900 is provided with an indication pattern 910 corresponding to the fluid delivery state of the pump assembly 200 and different from each other, and the indication pattern 910 is used to indicate the position of the switching operation part 232. Through the above structure, the current fluid delivery state of the pump assembly 200 can be indicated, which is convenient for actual use.
[0058] In the embodiment, the pump assembly 200 has three fluid delivery states, and the valve core 231 has three corresponding valve core positions, so three indication patterns 910 can be set for indication. In the embodiment, the valve core 231 adopts a rotating structure, and the switching operation part 232 is specifically a knob coaxially connected to the valve core 231. When the valve core 231 is operated, the valve core 231 can be driven to rotate by operating the knob. The indication pattern 910 is specifically arranged around the rotation axis of the valve core 231, and the knob is provided with an indication block. When the indication block points to a certain indication pattern 910, it can indicate the current position of the valve core 231 and the current fluid delivery state of the pump assembly 200.
[0059] It is conceivable that the switching operation part 232 is not limited to the structure of the above-mentioned knob, and its structure can be adaptively set according to the action mode of the valve core 231. For example, when the valve core 231 adopts axial movement to switch the valve core position, the switching operation part 232 can be a button structure. If the valve core 231 adopts axial movement to switch the valve core position, the indicator pattern 910 can be arranged along the axial direction, and the button is provided with an indicator scale to indicate the valve core position and the fluid delivery state of the pump assembly 200. In an embodiment, the indicator pattern 910 can be attached to the housing part 900 by mold forming, engraving, pasting, etc.

[0061] In an embodiment, the pump assembly 200 can be connected to the kettle body 100 via a threaded structure, so as to achieve detachability. Of course, it is conceivable that the pump assembly 200 can also be detachably connected via other structures, such as a snap connection, etc.
