[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0044] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0045] like Figures 1-10As shown, this application provides a solar drip irrigation device 10, which includes a housing 100, a receiving cavity 110, and a first shell 140. The side of the first shell 140 away from the receiving cavity 110 includes a mounting groove 141, that is, the outer side of the first shell 140 includes a mounting groove 141.

[0046] like Figure 2 As shown, the mounting groove 141 includes a mounting hole 142 communicating with the receiving cavity 110 and a first glue-filling groove 143 disposed around the mounting hole 142. Optionally, the mounting groove 141 includes a bottom wall 144 and an annular side wall 145, and the bottom wall 144 includes the mounting hole 142. The first glue-filling groove 143 is disposed on the periphery of the bottom wall 144 near the annular side wall 145.

[0047] like Figure 1 and Figure 4 As shown, the solar panel 700 includes a main plate 710, which is located in the mounting groove 141, and the main plate 710 is provided with an electrical connection area 711 corresponding to the mounting hole 142.

[0048] Optionally, a first glue-filling part (not shown) is connected between the main body plate 710 and the first glue-filling groove 143. That is, the first glue-filling part is provided in the first glue-filling groove 143 and is connected between the main body plate 710 and the first glue-filling groove 143 (first shell 140). This allows the first glue-filling part to form an annular closed structure around the mounting hole 142. It also works with the first shell 140 and the main body plate 710 to form a sealed structure that is isolated from the outside. This effectively prevents moisture from seeping in from the gap between the main body plate 710 and the mounting groove 141 and entering the receiving cavity 110 through the mounting hole 142.

[0049] In an optional scenario, sealant can be poured into the first glue-filling tank 143 (so that the sealant overflows), and then the solar panel 700 can be installed in the mounting groove 141. At this time, the solar panel 700 and the first glue-filling tank 143 squeeze the sealant, so that the sealant dries and forms the first glue-filling part.

[0050] In the above embodiment, by providing a mounting groove 141 on the side opposite to the receiving cavity 110 in the first shell 140 of the housing 100 of the solar drip irrigation device 10, and providing a mounting hole 142 communicating with the receiving cavity 110 in the mounting groove 141, and a first glue-filling groove 143 surrounding the mounting hole 142, and the solar panel 700 includes a main plate 710 located in the mounting groove 141, the main plate 710 having an electrical connection area 711 corresponding to the mounting hole 142, and a first glue-filling part connecting the main plate 710 and the first glue-filling groove 143, moisture can be effectively prevented from seeping in from the gap between the main plate 710 and the mounting groove 141 and entering the receiving cavity 110 through the mounting hole 142. This improves the waterproof effect and service life of the entire solar drip irrigation device 10.

[0051] like Figure 2 and Figure 3 As shown, the first shell 140 also includes a key through hole 146 communicating with the receiving cavity 110 and a second potting groove 127 provided on the side facing the receiving cavity 110, surrounding the key through hole 146.

[0052] The solar drip irrigation device 10 includes a button section 600, which includes a button body 610 located in the receiving cavity 110, a button 620 disposed on the button body 610 and passing through the button through hole 146, and a button ring plate section 670 disposed on the button body 610 and embedded in the second potting groove 127.

[0053] Among them, a second potting part (not shown) is connected between the button ring plate 670 and the second potting groove 127.

[0054] In an optional scenario, sealant can be poured into the second glue-filling groove 127 first, and then the button part 600 can be installed from one side of the receiving cavity 110 toward the first shell 140, so that the button 620 passes through the button through hole 146 and the button ring plate part 670 is embedded in the second glue-filling groove 127, and the sealant is squeezed together with the second glue-filling groove 127, so that after the sealant dries, a second glue-filling part is formed connecting the button ring plate part 670 and the second glue-filling groove 127. On the one hand, the nesting method makes the assembly of the button part 600 and the first shell 140 more stable, and the setting of the second glue-filling groove 127 and the button ring plate part 670 achieves multiple overlapping waterproofing, and the second glue-filling waterproofing part is connected between the second glue-filling groove 127 and the button ring plate part 670 to prevent moisture from entering the receiving cavity 110 from the assembly gap between the first shell 140 and the button part 600. This greatly improves the waterproofing capability of the solar drip irrigation device 10 and broadens its application scenarios.

[0055] like Figure 7 As shown, the solar drip irrigation device 10 also includes a knob 200, a knob bracket 300, and a first waterproof ring 400.

[0056] like Figure 2 and Figure 7 As shown, the first housing 140 includes a first knob through-hole 121 communicating with the receiving cavity 110. The housing 100 also includes a support plate 130 disposed on the side of the first housing 140 away from the receiving cavity 110, the support plate 130 being disposed around the first knob through-hole 121. Optionally, the support plate 130 forms a second knob through-hole 131 communicating with the first knob through-hole 121.

[0057] Optionally, the support plate 130 can be set around the first knob through hole 121, specifically around the central axis of the first knob through hole 121.

[0058] In an optional embodiment, the second knob through hole 131 and the first knob through hole 121 can be coaxially arranged.

[0059] like Figure 7 As shown, the knob 200 is rotatably mounted on the housing 100 and includes a main body 210 rotatably mounted to the support plate 130, a handle 220 mounted on the main body 210 and surrounding the support plate 130, and a first connecting portion 230 mounted on the main body 210 and at least partially located in the second knob through hole 131. The knob bracket 300 is at least partially disposed in the receiving cavity 110 and includes a second connecting portion 310 passing through the first knob through hole 121 and connected to the first connecting portion 230, and a blocking portion 320 surrounding the second connecting portion 310 and disposed opposite to the first housing 140.

[0060] Optionally, by providing the blocking part 320 and the first shell 140, the knob support 300 can be prevented from going out of the first knob through hole 121, so that the knob support 300 is at least partially and securely located in the receiving cavity 110.

[0061] like Figure 3 As shown, the first waterproof ring 400 is disposed between the main body 210 and the supporting enclosure 130.

[0062] In the above embodiments, by providing a second knob through hole 131 and a first knob through hole 121, and connecting the knob 200 and the knob bracket 300 through a first connecting portion 230 located at least partially in the second knob through hole 131 and a second connecting portion 310 located at least partially in the first knob through hole 121, and by rotating the knob 200 onto the housing 100 and providing a first waterproof ring 400 between the main body 210 of the knob 200 and the support plate 130 of the housing 100, the amount of liquid entering the second knob through hole 131, the first knob through hole 121, and the receiving cavity 110 through the gap between the main body 210 and the first waterproof ring 400 can be effectively reduced or prevented, thus ensuring the waterproofness of the entire solar drip irrigation device 10 and effectively reducing or preventing damage to the circuit board in the receiving cavity 110. Furthermore, by providing a support plate 130 that protrudes from the first shell 140, it can also block liquids that splash or drip onto the first shell 140 to a certain extent, preventing liquids from entering the second knob through hole 131, the first knob through hole 121, and the receiving cavity 110, thus making the entire solar drip irrigation device 10 have good waterproof performance.

[0063] like Figure 8 As shown, the first waterproof ring 400 includes a base 410 and a first water-stopping portion 420 and a second water-stopping portion 430 respectively disposed at both ends of the base 410. The first water-stopping portion 410, the second water-stopping portion 420, and the base 430 form a first water-stopping groove 440 and a second water-stopping groove 450. That is, the first water-stopping portion 420 and the second water-stopping portion 430 are disposed at the ends of the base 410 and extend toward both sides of the base 410, thereby forming a first water-stopping groove 440 and a second water-stopping groove 450 on both sides of the base 410 respectively.

[0064] Optionally, the opening directions of the first water-stop groove 440 and the second water-stop groove 450 are opposite, but both are located on the side away from the base 410.

[0065] like Figure 7 and Figure 9 As shown, the first waterproof ring 400 is fitted onto the support plate 130 through the first water-stop groove 440.

[0066] like Figure 7 As shown, the main body 210 also includes a support 211, which is nested in the second water stop groove 450 and is disposed opposite to the support enclosure 130.

[0067] Optionally, by setting the first waterproof ring 400 to a double-groove shape and respectively fitting it onto the support plate 130 and the support part 211, on the one hand, the support stability of the support plate 130 and the support part 211 can be improved, so that the knob 200 can be stably rotated and supported on the housing 100. On the other hand, multiple water-blocking structures are formed between the first water-stop groove 440 and the support plate 130, the second water-stop groove 450 and the support part 211 (such as between the support plate 130 and the first water-stop part 410, between the support plate 130 and the base 410, etc.), which can effectively prevent liquid from entering the second knob through hole 131, the first knob through hole 121 and the receiving cavity 110.

[0068] Optionally, the support portion 211 and the handle portion 220 are spaced apart to form a rotatable space between the knob 200 and the housing 100.

[0069] In an optional embodiment, the first waterproof ring 400 is a flexible structure.

[0070] In an optional embodiment, the first water-stop portion 420 is located away from the first connecting portion 230 relative to the second water-stop portion 430. That is, the first water-stop portion 420 is located outside the second water-stop portion 430, and the axial length of the first water-stop portion 420 is greater than that of the second water-stop portion 430. In other words, the length of the first water-stop portion 420 extending toward at least one side of the base 410 is greater than the length of the second water-stop portion 430.

[0071] In an optional embodiment, the length of the first water-stopping part 420 extending to both sides of the base 410 is greater than the length of the second water-stopping part 430.

[0072] Optionally, since the first water-stopping part 420 is located on the outer side relative to the second water-stopping part 430, it is more likely to come into contact with liquid. By increasing the length of the first water-stopping part 420, its contact area with the supporting plate 130 and / or the supporting part 211 can be increased, thereby improving the water-blocking effect of the water-blocking structure formed by the first water-stopping part 420 and the supporting plate 130 and / or the supporting part 211. This also improves the stability of the fit between the first waterproof ring 400 and the supporting plate 130 and / or the supporting part 211.

[0073] Optionally, the solar drip irrigation device 10 may also include a second waterproof ring (not shown) fitted onto the second connecting portion 310 and disposed between the blocking portion 320 and the first housing 140.

[0074] In an optional embodiment, by further providing a second waterproof ring between the blocking part 320 and the first shell 140, a waterproof structure can be further formed to prevent liquid or water vapor that has entered the second knob through hole 131 and the first knob through hole 121 from further entering the receiving cavity 110, thereby improving the overall waterproof effect.

[0075] like Figure 7 As shown, the blocking part 320 includes a stepped part 321 disposed near the second connecting part 310, the first shell 140 is provided with a stepped groove 121 corresponding to the stepped part 321, and the second waterproof ring is disposed between the stepped part 321 and the stepped groove 121.

[0076] Optionally, by providing a step portion 321 in the blocking portion 320 and a step groove 121 corresponding to the step portion 321 in the first shell 140, and placing the second waterproof ring between the step portion 321 and the step groove 121, the second waterproof ring can be positioned better between the blocking portion 320 and the first shell 140, reducing its shaking or displacement. On the other hand, it can effectively achieve contact between the blocking portion 320 and the second waterproof ring, and between the first shell 140 and the second waterproof ring from multiple directions, effectively improving the waterproof effect.

[0077] In an optional embodiment, both the first waterproof ring 400 and the second waterproof ring can be flexible structures, such as silicone rings or rubber rings, without specific limitations.

[0078] like Figure 4 As shown, the receiving cavity 110 also includes a PCB board mounting groove 111, a second potting groove 127, and at least a portion of the knob bracket 300 located in the PCB board mounting groove 111.

[0079] Optionally, the housing 100 may also include a mounting plate 150 disposed on the side of the first housing 140 facing the receiving cavity 110. The mounting plate 150 is disposed around the second potting groove 127, the knob bracket, etc., and the mounting plate 150 and the first housing 140 enclose each other to form the PCB board mounting groove 111.

[0080] like Figure 5 As shown, the solar drip irrigation device 10 also includes a PCB board 800 disposed in a PCB board mounting groove 111. The PCB board 800 is located in the PCB board mounting groove 111, so that there is still some space on the side of the PCB board mounting groove 111 away from the PCB board 800.

[0081] Optionally, the PCB mounting slot 111 is located on the side of the PCB board 800 opposite to the first shell 140 and is also provided with a PCB potting layer (not shown).

[0082] In an optional scenario, after the PCB board 800 is installed in the PCB board mounting slot 111, there is still some space in the PCB board mounting slot 111 on the side of the PCB board 800 away from the first shell 140. Then, sealant is poured into these spaces in the PCB board mounting slot 111. After the sealant dries, a PCB potting layer can be formed, which can effectively seal from the receiving cavity 110 side to prevent moisture from entering the electronic components of the PCB board 800.

[0083] Optionally, the knob bracket 300 is provided with a contact plate, the button 620 is provided with a pressing element, and the PCB board 800 includes an electrical connection area that mates with the contact plate and a pressing area that mates with the pressing element.

[0084] like Figure 1 As shown, the housing 100 also includes a second housing 180, and the first housing 140 and the second housing 180 are nested together to form a receiving cavity 110.

[0085] Optionally, the edge of the first shell 140 is provided with a nesting groove, and the edge of the second shell 180 is provided with a nesting plate. Through the nesting cooperation of the nesting plates, the first shell 140 and the second shell 180 are nested together. This cooperation can effectively improve the stability of installation and improve the waterproof performance.

[0086] like Figure 4 As shown, the solar drip irrigation device 10 also includes a battery assembly 900 disposed within the receiving cavity 110, and an electrical connection area 711 is electrically connected to the battery assembly 900. Optionally, the electrical connection area 711 and the battery assembly 900 can be directly or indirectly connected, thereby supplying power to the battery assembly 900 through the solar panel 700.

[0087] In an alternative embodiment, the battery assembly 900 may be a lithium battery.

[0088] In an optional embodiment, the housing 100 includes a battery mounting enclosure 190 disposed on the side of the first housing 140 facing the receiving cavity 110. The battery mounting enclosure 190 and the first housing 140 enclose a battery mounting groove 112, in which the battery assembly 900 can be installed.

[0089] like Figure 4 As shown, the battery mounting slot 112 is located in the direction of the battery assembly 900 away from the first shell 140 and is also provided with a battery potting layer (not shown).

[0090] In an optional scenario, after the battery assembly 900 is installed in the battery mounting slot 112, there is still some space in the battery mounting slot 112 on the side of the battery assembly 900 away from the first shell 140. Then, sealant is poured into these spaces in the battery mounting slot 112. After the sealant dries, a battery potting layer can be formed, which can effectively seal from the receiving cavity 110 side to prevent moisture from entering the battery contact points.

[0091] like Figure 1 As shown, the solar drip irrigation device 10 also includes a ground-mounted assembly 181 disposed on the second housing 180 in a direction away from the first housing 140. Optionally, the solar drip irrigation device 10 can be fixed to the ground or the like by the ground-mounted assembly 181, thereby allowing the solar drip irrigation device 10 to be stably installed, thus ensuring that the solar panel 700 can face the sky.

[0092] In an alternative embodiment, the solar drip irrigation device 10 may also include a water valve assembly located in the receiving cavity 110.

[0093] In a specific scenario, the solar drip irrigation device 10 can obtain solar energy through the solar panel 700 to charge the battery component 900, thereby powering the entire solar drip irrigation device 10, which in turn drives the water valve component, thus achieving controllable drip irrigation.

[0094] In summary, the solar drip irrigation device 10 provided in this application has an installation groove 141 on the side opposite to the receiving cavity 110 in the first shell 140 of the housing 100 of the solar drip irrigation device 10. The installation groove 141 has an installation hole 142 communicating with the receiving cavity 110 and a first glue-filling groove 143 surrounding the installation hole 142. The solar panel 700 includes a main plate 710 located within the installation groove 141. The main plate 710 has an electrical connection area 711 corresponding to the installation hole 142. A first glue-filling part connects the main plate 710 and the first glue-filling groove 143. This effectively prevents moisture from seeping in through the gap between the main plate 710 and the installation groove 141 and entering the receiving cavity 110 through the installation hole 142. This improves the waterproof effect and service life of the entire solar drip irrigation device 10.
