FIG. 2 is a schematic block diagram of the plant infusion device 10 according to the first embodiment of the present invention. The plant infusion device 10 includes an infusion bucket 11 , a syringe 17 , a pump 13 and a high-voltage switch 15 . The pump 13 is connected between the infusion bucket 11 and the syringe 17 (specifically, it is connected between the infusion bucket 11 and the high pressure switch 15 ). The high pressure switch 15 is connected between the syringe 17 and the pump 13 (specifically, is connected between the syringe 17 and the pump 13 ).

The syringe 17 is inserted into the plant 100 to inject the nutrient solution into the plant 100 . Specifically, one end of the syringe 17 is inserted into the plant 100, and the other end of the syringe 17 is connected to the high pressure switch 15, so as to obtain the nutrient solution from the infusion bucket 11 through the high pressure switch 15 and the pump 13, and inject the obtained nutrient solution into the plant. 100. The plant 100 may be a woody plant, such as agarwood.

The pump 13 is used to extract the nutrient solution from the infusion bucket 11 to the syringe 17 . In some embodiments, the pump 13 includes a water inlet end (hereinafter referred to as the first water inlet end 30 ) and a water outlet end (hereinafter referred to as the first water outlet end 31 ), and the first water inlet end 30 is connected to the infusion solution In the barrel 11 , the first water outlet 31 is connected to the syringe 17 via the high pressure switch 15 . The pump 13 pressurizes the nutrient solution from the first water inlet end 30 to deliver the nutrient solution to the syringe 17 through the first water outlet end 31 and the high pressure switch 15 . The pump 13 may be a volumetric pump, a dynamic pump, an electromagnetic pump or the like.

When the high pressure switch 15 detects that the water pressure of the plant 100 is not less than a full water threshold, the pump 13 is turned off and the nutrient solution is stopped. In some embodiments, the high-voltage switch 15 includes an elastic member (hereinafter referred to as a first elastic member) (not shown), a micro switch (hereinafter referred to as a first micro switch) (not shown), an input A water end (hereinafter referred to as the second water inlet end 32 ) and a water outlet end (hereinafter referred to as the second water outlet end 33 ). The second water inlet end 32 is connected to the first water outlet end 31 of the pump 13 , and the second water outlet end 33 is connected to the syringe 17 . The first elastic member is composed of an elastic membrane (hereinafter referred to as the first elastic membrane) and an actuating member (hereinafter referred to as the first actuating member) connected with the first elastic membrane. The first elastic membrane is disposed between the second water outlet end 33 and the syringe 17 . The first micro switch has a driving member (hereinafter referred to as the first driving member) to control the first micro switch to be turned on or off (for example, in some cases, the first driving member is squeezed by an external force, resulting in The first micro switch is turned off, and in other cases, the first driving member is lifted by an external force, so that the first micro switch is turned on).

When the high pressure switch 15 detects that the water pressure of the plant 100 is not less than the full water threshold (that is, when the water pressure of the plant 100 is not less than the elastic force provided by the first elastic membrane), the water pressure of the plant 100 pushes the first elastic membrane , so as to drive the first actuating member to displace and squeeze the first driving element, thereby linking the first microswitch to be turned off (eg, in a non-conducting state), thereby cutting off the power supply of the pump 13 . In this way, the plant infusion device 10 can automatically stop infusion when the water in the plant 100 reaches a saturated state, so that the plant 100 will not absorb excess nutrient solution.

In some embodiments, when the high pressure switch 15 detects that the water pressure of the plant 100 is lower than the full water threshold, the pump 13 is turned on to resume extracting the nutrient solution. For example, when the high-voltage switch 15 detects that the water pressure of the plant 100 is lower than the elastic force provided by the first elastic film (the water-filled threshold), the elastic force of the first elastic film drives the first actuator to displace and reset. Thus, the first driving element is lifted, so that the first microswitch is turned on (eg, in a conducting state), and the power supply of the pump 13 is restored. In this way, the plant infusion device 10 can automatically infuse the plant 100 when the water in the plant 100 is not saturated, so that the plant 100 can absorb an appropriate amount of nutrient solution and be in an optimal growth state.

When the low pressure switch 19 detects that the water pressure of the infusion bucket 11 is not greater than the water shortage threshold (for example, when the water pressure of the infusion bucket 11 is not greater than the elastic force provided by the second elastic film), the elastic force provided by the second elastic film The force drives the second actuating member to displace and lift the second driving element, thereby interlocking the second microswitch to close (for example, a non-conductive state), thereby cutting off the power supply of the pump 13 . In this way, the pump 13 can be prevented from being burnt due to idling due to continuous operation when the infusion bucket 11 is not filled with the nutrient solution.

In some embodiments, when the low pressure switch 19 detects that the water pressure of the infusion bucket 11 is greater than the water shortage threshold, the pump 13 is turned on to resume the extraction of nutrient solution. For example, when the low pressure switch 19 detects that the water pressure of the infusion bucket 11 is greater than the elastic force (water shortage threshold) provided by the second elastic membrane, the water pressure of the infusion bucket 11 pushes the second elastic membrane to drive the second elastic membrane. The actuating member is displaced and reset, thereby compressing the second driving element, so that the second microswitch is turned on (eg, in a conducting state), and the power supply of the pump 13 is restored. In this way, the plant infusion device 10 can automatically restore the pump 13 to extract the nutrient solution when the infusion bucket 11 contains the nutrient solution.
