Referring to fig. 1, the rainfall detection device 020 of the present embodiment includes a detection tank 200 and a detection component 210 disposed at the bottom of the detection tank 200, wherein the detection component 210 is used for detecting raindrops.

The rain collecting unit 100 is disposed above the detection tank 200, and the droplet outlet 101 faces the detection unit 210, so that the detection unit 210 can detect the droplet dropped from the droplet outlet 101.

Referring to fig. 3, the bottom of the detection tank 200 of the present embodiment has a water guiding inclined plane 220, and the detection tank 200 is provided with a water outlet hole 201; the water guide slope 220 is used for receiving the liquid flowing down from the detection assembly 210 and guiding the liquid to flow to the water outlet hole 201; thus, the liquid drops (for example, raindrops) dropping on the detection module 210 for detection can flow to the water guide slope 220, flow to the water outlet hole 201 under the guidance of the water guide slope 220, and flow out from the detection tank 200, so that the water accumulation in the detection tank 200 can be avoided, the liquid flow into the detection module 210 can be reduced, the wetting of the circuit in the detection module 210 by the liquid drops can be reduced, the short circuit of the circuit can be avoided, and the safety of the use of the rainfall detection device 020 can be facilitated.

In this embodiment, the water outlet hole 201 is opened on the side wall of the detection tank 200, that is, the water guide slope 220 can guide the raindrops to flow toward the side wall of the detection tank 200, and the raindrops are discharged from the water outlet hole 201 on the side wall of the detection tank 200.

In other embodiments, the water outlet 201 may also be opened in the bottom wall of the detection tank 200; the water outlet hole 201 formed in the bottom wall is located downstream of the water guide slope 220 for guiding the flow of the liquid.

It should be noted that, no matter the water outlet hole 201 is opened on the side wall of the detection tank 200, or is opened on the bottom wall of the detection tank 200 and is located at the downstream where the water guide inclined plane 220 guides the liquid to flow, it can be effectively ensured that raindrops entering the detection tank 200 are far away from the position where the raindrops flow far away from the detection component 210, so as to effectively avoid the short circuit of the detection component 210.

The detecting component 210 is disposed at a substantially central position of the water guide slope 220; it can also be regarded that the bottom of the detection tank 200 has two water guide slopes 220, and the detection assembly 210 is located between the two water guide slopes 220; thus, after raindrops are detected by the detection assembly 210, the raindrops can flow to both sides, the water guide slopes 220 on both sides of the detection assembly 210 can receive liquid, and then the raindrops can be more effectively prevented from flowing into the detection assembly 210 through the water guide slopes 220 on both sides of the detection assembly 210, so that the short circuit of the detection assembly 210 is avoided.

The inclined directions of the water guide slopes 220 on both sides of the detection assembly 210 are the same, so that raindrops can be guided away from the detection assembly 210 in the same direction, and the raindrops are further effectively prevented from flowing into the detection assembly 210, so as to prevent a short circuit of the detection assembly 210.

Referring to fig. 3, the bottom plate of the detection tank 200 of the present embodiment further has a step portion 230, the detection element 210 is disposed on the step portion 230, and the detection end 213 of the detection element 210 protrudes from the step portion 230 for receiving the liquid drop to be detected; the water guiding slope 220 is located below the step part 230, and the step part 230 is used for receiving the liquid flowing down from the detection assembly 210 and making the liquid flow to the water guiding slope 220 along the step part 230; thus, raindrops dropping on the detection assembly 210 can flow along the step portion 230 to the water guide slope 220 below the step portion 230, so as to raise the height of the detection assembly 210 by the step portion 230, thereby further preventing the raindrops from entering the circuit of the detection assembly 210.

Referring to fig. 3, the step part 230 is further provided with a blocking part 240, and the blocking part 240 and the detecting end 213 of the detecting assembly 210 are distributed on the same side of the step part 230; the blocking portion 240 is located downstream of the sensing member 210 in a direction in which the liquid flows on the water guide slope 220, and is used for limiting a flow direction of the liquid flowing down from the sensing member 210. In the direction of the liquid flowing on the water guiding slope 220, the blocking portion 240 can block the liquid from flowing downstream on the surface of the step portion 230, so as to promote the liquid flowing down from the detection assembly 210 to flow down along the step portion 230 to the water guiding slope 220.

Referring to fig. 3, the step portion 230 of the present embodiment includes a first step 231 and a second step 232 disposed on the first step 231, and the detecting end 213 protrudes from the second step 232; the first step 231 protrudes from the second step 232 along the upstream of the flowing direction of the liquid on the water guide inclined plane 220, that is, the section of the first step 231 is larger than that of the second step 232; the liquid flowing down from the detection component 210 can flow through the second step 232, the first step 231 and the water guide inclined plane 220 in sequence, namely, according to the setting direction of the rainfall device during use, the second step 232, the first step 231 and the water guide inclined plane 220 are distributed from top to bottom in sequence, so that the liquid flowing down from the detection component 210 can be finally carried by the water guide inclined plane 220 and flows to the water outlet hole 201 under the guide of the water guide inclined plane 220.

It should be noted that the blocking portion 240 protrudes from the upper surface of the second step 232, so that the blocking portion 240 can block the liquid from flowing downstream on the upper surface of the second step 232.

In other embodiments, the stepped part 230 may include only one protrusion protruding from the water guide slope 220.

The blocking part 240, the stepped part 230 and the water guide slope 220 of the present embodiment are integrally formed; in other embodiments, the blocking portion 240, the stepped portion 230 and the water guiding slope 220 may be bonded or welded.

Referring to fig. 3, the detecting assembly 210 includes an installation base 211 and a plurality of detecting electrodes 212, the installation base 211 is provided with a plurality of insertion holes (not shown), the plurality of detecting electrodes 212 are in one-to-one correspondence and are in insertion fit with the plurality of insertion holes, the installation base 211 is disposed on the step portion 230, referring to fig. 2, each of the plurality of detecting electrodes 212 has a detecting end 213, the detecting end 213 of the detecting electrode 212 extends out of the upper surface of the step portion 230, and the detecting ends 213 of the plurality of detecting electrodes 212 jointly form a detecting surface, and the detecting surface is distributed opposite to the droplet outlet 101 of the rain collecting assembly 100; the raindrops falling from the droplet outlet 101 can be dropped onto the detection surface to contact the detection end 213 of the detection electrode 212, and the droplets are detected by the detection electrode 212.

Referring to fig. 3, an installation opening 233 is formed on an upper surface of the second step 232, the installation opening 233 is adapted to the installation seat 211, and the installation seat 211 is inserted into the installation opening 233; on one hand, the mounting seat 211 and the detection electrode 212 can be arranged on the step part 230 by using the mounting opening 233; on the other hand, the mounting seat 211 seals the mounting opening 233, and prevents liquid from flowing from the mounting opening 233 to the lower side of the step portion 230.

A waterproof tape may be interposed between the mounting seat 211 and the mounting opening 233 to prevent liquid from flowing below the step 230.

It should be noted that the end of the detection electrode 212 far from the detection end 213 can be electrically connected to the detection circuit, so that when a liquid droplet lands on the detection end 213, the electrical signal of the detection circuit is changed, and the rainfall and the like are calculated according to the change of the electrical signal of the detection circuit. It should be further noted that the detection circuit may be disposed below the step portion 230 or below the water guide slope 220, that is, the detection circuit may be disposed at any position outside the bottom of the detection tank 200, and since the mounting opening 233 of the second step 232 is blocked by the mounting seat 211, the detection circuit is not easily wetted and is not easily short-circuited when encountering water.

It should be further noted that the positive electrodes and the negative electrodes are sequentially and alternately distributed in the plurality of detection electrodes 212, so that raindrops dropping from the drop outlet 101 can be in contact with the positive electrodes and the negative electrodes, thereby improving the detection accuracy.

In the present embodiment, the plurality of detection electrodes 212 are all disposed perpendicular to the upper surface of the stepped portion 230, and the detection surface is parallel to the upper surface of the stepped portion 230, that is, the plurality of detection electrodes 212 are all disposed perpendicular to the upper surface of the second step 232, and the detection surface is parallel to the upper surface of the second step 232; thus, even when the rainfall detection module 210 is not placed on a horizontal surface, that is, when the detection surface is not placed on a horizontal surface, the raindrops dropping from the droplet outlet 101 can be brought into contact with the detection end 213 of the detection electrode 212 forming the detection surface, thereby facilitating detection with high accuracy and eliminating the need for severe mounting conditions.

Referring to fig. 2, the exterior of the detection electrode 212 is wrapped by the insulating outer sleeve 214, and only the end of the detection electrode 212 facing the droplet outlet 101 is exposed out of the insulating outer sleeve 214 as the detection end 213, so that the droplet falling on the detection electrode 212 flows to the step 230 and the water guide inclined plane 220 along the insulating outer sleeve 214 in sequence after contacting the detection end 213, and does not remain on the detection electrode 212, that is, when the rainfall is large, the situation that the former raindrop still occupies the detection electrode 212 and the latter raindrop falls to cause the detection circuit to judge that only one raindrop exists is avoided, and the instantaneity and the accuracy of raindrop detection are ensured; it can also be understood that the accuracy of the rainfall detection can be ensured by rapidly draining the rainwater flowing into the detection tank 200 through the insulating outer sleeve 214 and the water guide slope 220.

Referring to fig. 3, the rainfall detection device 020 of the present embodiment further includes a draft tube 202 disposed in the detection tank 200, the draft tube 202 is communicated with the inside of the detection tank 200 through the water outlet 201, and the draft tube 202 is configured to discharge the liquid drained by the water guide slope 220 out of the detection tank 200; through the arrangement of the draft tube 202, raindrops entering the detection tank 200 can be further kept away from the detection component 210 at the bottom of the detection tank 200, and further, the short circuit of the detection component 210 is effectively avoided.

The draft tube 202 of the present embodiment is disposed opposite to the water guide slope 220, that is, the liquid flowing from the water guide slope 220 to the draft tube 202 can basically flow according to the original flow path; this can effectively improve the efficiency of discharging the liquid from the detection tank 200.

The number of the water outlet holes 201 arranged on the detection tank 200 and the number of the draft tubes 202 arranged on the detection tank 200 can be selected according to the requirement; two apopores 201 have been seted up to the detection groove 200 of this embodiment, and detect that groove 200 corresponds and still be provided with two honeycomb ducts 202, and two honeycomb ducts 202 communicate with the inside of detecting groove 200 through the apopore 201 that corresponds respectively.

When raindrops in the rain collecting assembly 100 flow to the detection surface through the liquid drop outlet 101, the detection end 213 of the detection electrode 212 constituting the detection surface contacts with the raindrops, so that an electrical signal of a detection circuit electrically connected to the detection electrode 212 can be changed, the detection circuit transmits the electrical signal to the circuit assembly 310, and the circuit assembly 310 calculates rainfall according to the received electrical signal.

Further, when each raindrop contacts the detection end 213, the detection circuit may transmit an electrical signal to the circuit component 310 once, and the circuit component 310 may count once, that is, one raindrop, and finally, the circuit component 310 may calculate the rainfall in unit time or unit area according to the recorded raindrop number and the weight of each raindrop; the specific calculation method is similar to that of the related art, and is not described herein again.
