[0027] Referring to the drawings Figure 1The embodiment provides a water purifier, which comprises a shell 1 with a bottom surface; a water leakage detection assembly 2 arranged in the shell 1 and comprising a control component 21, a cover component 22, a first detection component 24 and a second detection component 25 arranged at intervals; the control component 21 is electrically connected with the first detection component 24 and the second detection component 25 respectively, the cover component 22 covers the first detection component 24 and the second detection component 25, and the first detection component 24 and the second detection component 25 are both arranged at intervals from the bottom surface, and the intervals can accommodate water; in the case that water in the intervals contacts the first detection component 24 and the second detection component 25, the first detection component 24 and the second detection component 25 can conduct electricity through the water, so that the first detection component 24, the second detection component 25 and the control component 21 form a detection loop.

[0028] It should be noted that, in the embodiment, the intervals are arranged between the first detection component 24 and the second detection component 25 and the bottom surface, and the intervals can accommodate water, in the case that the water level rises to be in communication with the first detection component 24 and the second detection component 25, the first detection component 24 and the second detection component 25 conduct electricity through the water, the first detection component 24, the second detection component 25 and the control component 21 form a detection loop, the rapid detection of water leakage of the water purifier is realized, the use is safe and reliable, and for small-flow leakage, the leakage can also be effectively found and solved; meanwhile, the cover component 22 is arranged above the first detection component 24 and the second detection component 25, which can avoid that water drops between the first detection component 24 and the second detection component 25 to cause the two components to conduct electricity, and further can avoid false positives, improve detection accuracy, and improve user experience.

[0029] In the embodiment, the water leakage detection assembly 2 is vertically arranged in the shell 1.

[0030] In the embodiment, the control component 21 comprises an integrated circuit with chip processing, integrated display and voice prompt, and has functions such as detecting water leakage, real-time display and voice broadcast; specifically, in the case that the first detection component 24 and the second detection component 25 conduct electricity through water in the gap, the control component 21 can detect the signal of the conduction of the first detection component 24 and the second detection component 25, when the time corresponding to the conduction is greater than a preset time, it is indicated that the water purifier leaks, the control component 21 displays water leakage fault information, the water purifier stops the opening and closing of all pumps and valves, and the control component 21 broadcasts the water leakage fault information.

[0031] Specifically, after the water leakage detection of the water purifier is started, if the water purifier leaks, when the amount of water leakage exceeds the volume of the water collecting tank 11, the control member 21 detects that the first detection member 24 and the second detection member 25 are connected, and starts to count the duration; if the duration is greater than the preset duration, it is considered that the water purifier has leaked, the control member 21 controls all the pumps and valves to stop working, displays the water leakage and voice broadcasts the water leakage fault; after the water leakage position is repaired, the control member 21 detects that the first detection member 24 and the second detection member 25 are not connected, starts to count the duration, and if the duration is greater than the preset duration, the water purifier clears the water leakage fault information, and the water purifier operates normally.

[0032] In the embodiment, the shape and size of the cover member 22 are not limited, as long as the cover member 22 can cover the first detection member 24 and the second detection member 25.

[0033] In some possible embodiments, the water leakage detection assembly 2 further comprises an isolation member 23, which is used to isolate the first detection member 24 and the second detection member 25. By arranging the isolation member 23, the first detection member 24 and the second detection member 25 can be isolated, so as to avoid that the first detection member 24 and the second detection member 25 are conducted in the case that the water purifier does not leak, thereby avoiding false positives and improving detection accuracy and user experience.

[0034] Specifically, the left and right sides of the isolation member 23 are provided with a first containing space and a second containing space which are independent of each other, the first containing space is used to contain the first detection member 24, and the second containing space is used to contain the second detection member.

[0035] Specifically, the first containing space and the second containing space are non-closed spaces, so that water can enter the containing space, and the first detection member 24 and the second detection member 25 are conducted.

[0036] Further, along the height direction of the water purifier, the cross section of the isolation member 23 is a T-shaped cross section.

[0037] In the embodiment, the shell 1, the isolation member 23 and the cover member 22 are all non-conductive.

[0038] Specifically, the control member 21 is electrically connected with the first detection member 24 and the second detection member 25 through two wires 27, respectively. Since the first detection member 24 and the second detection member 25 are arranged on the left and right sides of the isolation member 23, the two wires 27 are also connected from the left and right sides of the isolation member 23, which can further prevent false connection.

[0039] In some possible embodiments, the height of the isolation piece 23 is not less than the height of the first detection piece 24. By setting the height of the isolation piece 23 to be greater than or equal to the height of the first detection piece 24, it can be ensured that the isolation piece 23 sufficiently isolates the first detection piece 24 and the second detection piece 25, avoiding the case that only part of the first detection piece 24 and the second detection piece 25 is isolated. On the basis of setting the cover piece 22, it is further avoided that the first detection piece 24 and the second detection piece 25 are conducted in the case that the water purifier does not leak, thereby avoiding the false alarm and improving the detection accuracy and the user experience.

[0040] Specifically, the isolation piece 23 isolates the first detection piece 24 and the second detection piece 25, and covers the first detection piece 24 and the second detection piece 25 from above, further avoiding that the first detection piece 24 and the second detection piece 25 are conducted due to the water dripping from above.

[0041] In some possible embodiments, the bottom surface is provided with a water collecting groove 11 for containing water, and the cross-sectional area of the water collecting groove 11 is less than the area of the bottom surface. By setting the cross-sectional area of the water collecting groove 11 to be less than the area of the bottom surface, the water leaking from the water purifier can be collected in the water collecting groove 11, and the water leaking from the water purifier can be collected. In the case that the size of the water collecting groove 11 is small, a small amount of water leakage can cause the liquid level in the water collecting groove 11 to rise, which can improve the detection accuracy.

[0042] In the embodiment, the water leakage detection assembly 2 is arranged in the middle region of the water collecting groove 11.

[0043] Specifically, the water storage capacity of the water collecting groove 11 can be adjusted according to the actual demand by adjusting the length, width or height of the water collecting groove 11.

[0044] Further, the water collecting groove 11 is formed by stamping with a stamping die.

[0045] In some possible embodiments, the bottom surface of the first detection piece 24 is arranged flush with the top surface of the water collecting groove 11. By setting the bottom surface of the first detection piece 24 to be flush with the top surface of the water collecting groove 11, it can be ensured that the water in the water collecting groove 11 can contact the first detection piece 24 and the second detection piece 25 in the case that the water in the water collecting groove 11 exceeds the top surface of the water collecting groove 11, the first detection piece 24 and the second detection piece 25 are conducted, the rapid detection of the water leakage of the water purifier is realized, and the use is safe and reliable.

[0046] In some possible embodiments, the isolation piece 23 is fixedly arranged on the side wall of the shell 1, and the isolation piece 23 has a spacing from the bottom surface. By fixing the isolation piece 23 on the side wall of the shell 1, the installation structure is simplified, the isolation piece 23 can isolate the first detection piece 24 and the second detection piece 25, and the water leakage detection assembly 2 can be fixedly arranged on the side wall of the shell 1.

[0047] In some possible embodiments, the water leakage detection assembly 2 further comprises a fixing seat 26, a first end of the fixing seat 26 is fixedly connected with the bottom surface, the first detection member 24 and the second detection member 25 are fixed at a second end of the fixing seat 26, by arranging the fixing seat 26, the water leakage detection assembly 2 is fixed on the bottom surface of the shell 1, without adjusting the installation height, as long as the isolation member 23 is fixed on the fixing seat 26, the first detection member 24 and the second detection member 25 can have a spacing between the bottom surface, which reduces the installation difficulty.

[0048] Specifically, the height of the fixing seat 26 is consistent with the height of the water collecting groove 11, so that when the amount of water leakage exceeds the volume of the water collecting groove 11, the control member 21 can detect that the first detection member 24 and the second detection member 25 are turned on.

[0049] Specifically, the length of the fixing seat 26 is less than 30% of the length of the water collecting groove.

[0050] Specifically, the fixing seat 26 is adhesively fixed on the bottom surface of the shell 1, or the fixing seat 26 is detachably fixed on the bottom surface of the shell 1 through a connecting member.

[0051] In some possible embodiments, the first detection member 24 comprises a first detection end, the second detection member 25 comprises a second detection end, the first detection end and the second detection end can be turned on by water, and the first detection end and the second detection end are located at the same horizontal plane, by arranging the first detection end and the second detection end at the same horizontal plane, it can be ensured that the first detection end and the second detection end are contacted with water at the same time, and the response speed of water leakage detection is improved.

[0052] In the embodiment, the first detection member 24 and the second detection member 25 are electrodes, and the anode of the first detection member 24 and the cathode of the second detection member 25 are located at the same horizontal plane.

[0053] In some possible embodiments, the bottom surface is provided with at least one through hole 12, by arranging the through hole 12 on the ground, it can be ensured that when some water is spilled due to human maintenance or replacement of the filter element, the water will slowly flow away through the through hole 12, which prevents water accumulation from causing the bottom surface of the shell 1 to rust, thereby reducing the maintenance cost and improving the service life of the water purifier.

[0054] In the embodiment, the number of the through holes 12 is not set, as long as the water in the shell 1 can flow away.

[0055] Preferably, the ground is provided with two through holes 12, and the two through holes 12 are symmetrically arranged on both sides of the water leakage detection assembly 2.

[0056] In some possible embodiments, the diameter of the through hole 12 is 1-5 mm. By setting the size of the through hole 12 in the range as above, the speed of water flow in the water collecting groove 11 can be ensured to be less than the speed of water leakage accumulation, so that in the case of water leakage, the liquid level in the water collecting groove 11 can also rise.

[0057] In this embodiment, the diameter of the through hole 12 is 1-5 mm, 1-2 mm, 1-4 mm, 1-5 mm, 2-4 mm, 2-5 mm, 3-5 mm, or 3-5 mm, etc.

[0058] In this embodiment, the diameter of the through hole 12 is inversely proportional to the number of the through holes 12. If the number of the through holes 12 increases, the diameter of the through hole 12 needs to be reduced. In this way, the speed of water flow in the water collecting groove 11 can be ensured to be less than the speed of water leakage accumulation.

[0059] The water leakage detection process of the water purifier: during the working process of the water purifier, if the water fills the water collecting groove 11, the first detection piece 24 and the second detection piece 25 are conductive. At this time, the control piece 21, the first detection piece 24 and the second detection piece 25 form a detection loop, and the control piece 21 can obtain the connection information of the first detection piece 24 and the second detection piece 25. The control piece 21 counts the duration of conduction. If the duration of conduction is greater than the preset duration, it indicates that the water purifier leaks.
