Detailed Description
The present application is described in further detail below in conjunction with figures 1-3.
The embodiment of the application discloses a cleaning robot back wind channel and negative pressure independently closed water retaining structure.
Referring to fig. 1, the cleaning robot rear duct and the negative pressure autonomous closing water blocking structure includes: the sewage tank cover 1, the negative pressure connecting pipe II 2 and the press seal sealing ring 3.
In one implementation of the present application, the present application is built into a water storage mechanism of a cleaning robot as shown in the drawings, the water storage mechanism comprising:
referring to fig. 1 and 2, a clear water tank 91 and a sewage tank 92, wherein the middle of the clear water tank 91 is recessed downwards to form a tank groove, and the tank groove is opened; the sewage tank 92 is inserted into the tank from top to bottom for installation, the upper portion of the sewage chamber of the sewage tank 92 is opened, and the upper portion of the sewage tank cover 1 is closed. Meanwhile, the clean water tank 91 is also concavely formed with a fan groove in which a fan group 93 is installed to generate pumping power.
It is understood that the core of the present application is not a water storage mechanism, and other structures are specifically explained in other patents of the applicant, so that detailed explanation of the mechanism of the present application is mainly omitted.
In one embodiment of the present application, the negative pressure adapter tube two 2 is formed on the inner wall of the sewage tank 92 and faces a preset draining frame; one end of the negative pressure connecting pipe II 2 arranged in the sewage tank 92 is inclined upwards, and the other end of the negative pressure connecting pipe II penetrates through the side wall of the sewage tank 92 and is used for being communicated with a fan groove in the clean water tank 91, namely, an air inlet of the ventilator unit 93 is connected, so that a negative pressure air channel for completing suction is formed.
Referring to fig. 2 and 3, a transition air chamber is formed in the sewage tank cover 1, a transition air inlet and a transition air outlet 4 are formed in the lower portion of the sewage tank cover, and both air inlets are communicated with the transition air chamber; the transition air inlet is positioned above the draining frame; the transition air outlet 4 is positioned right above the negative pressure connecting pipe II 2.
The press seal ring 3 is fixed at the lower part of the sewage tank cover 1 and is arranged around the transition air outlet 4. When the sewage tank cover 1 is covered on the sewage tank 92, the press seal ring 3 is pressed against the inner end of the negative pressure take-over pipe 2 (the end inside the sewage tank 92).
As can be seen from the above, the air in the sewage tank 92 is sucked by the blower, and needs to enter the transition air chamber of the sewage tank cover 1 from the inner chamber of the sewage tank 92, then enter the negative pressure connection pipe 2 from the transition air outlet 4, and then enter the blower groove. In the process, the sewage tank cover 1 is pulled downwards under the action of negative pressure, so that the press seal sealing ring 3 is tightly pressed on the negative pressure connecting pipe II 2, the sewage tank cover 1 can be reliably covered, and the negative pressure suction effect of the cleaning robot is ensured.
In order to ensure that the side gap of the negative pressure connecting pipe II 2 can be sealed by the press seal ring 3 when the sewage tank cover 1 is covered, a limiting ring is downwards formed on the lower surface of the press seal ring 3 around the outer ring.
Based on the above, the second negative pressure connecting pipe 2 surrounds the port of the second negative pressure connecting pipe 2 in the closing stage of the sewage tank cover 1; at this time, even if the negative pressure adapter tube two 2 is slightly shifted relatively, there is no air leakage area.
In one embodiment of the application, in order to avoid that lighter dirt and partial sewage are continuously sucked by the rear air duct, a fixing frame 5 is arranged in the transition air inlet in a penetrating manner, the lower end of the fixing frame 5 extends out of the sewage tank cover 1 and is turned outwards, and the turning part is fixed on the sewage tank cover 1 through bolts. A filter block, which may be a sponge block or the like, is fixed in the fixing frame 5, and is ventilated but can block dirt.
In one embodiment of the application, the middle part of the upper part of the sewage tank cover 1 is provided with an upward bulge, namely the upper part of the transition wind cavity is provided with a concave part, and the concave part is upward concave; the vertical projection of the concave part covers the transition air inlet.
The concave part can enable the height of the transition air cavity to be higher, and the air flowing space to be larger, so that sewage is not easy to be continuously sucked; it may also cooperate with the side walls of the fixed frame 5 so that the suction force is mainly upward, not transverse. What needs to be known is: the smaller the air duct is, the larger the suction force is, and the sewage can be continuously sucked from the transition air inlet and the filter block without the structure.
In one embodiment of the application, the sewage tank cover 1 comprises a top cover and a plugging cover below the top cover; wherein the top cover is positioned outside the sewage tank 92, and the plugging cover is positioned inside the sewage tank 92.
A ring groove 6 is formed around the plugging cover, and a side sealing ring 7 is arranged in the ring groove; the outer side of the side sealing ring is abutted against the inner side of the opening of the sewage tank.
The arrangement can further ensure the compactness of the sewage tank cover 1 after the sewage tank cover 1 is covered, prevent air leakage from influencing negative pressure suction and avoid noise.
Further, a plurality of prismatic grooves are formed around the outer side of the side sealing ring 7, so that a sealing sheet structure with a laminated structure distribution is formed outside the side sealing ring 7. This configuration helps to further isolate the outside and interior chambers of the tank 92.
Referring to fig. 2, in one embodiment of the present application, the external port of the negative pressure adapter tube 2 is provided with a vertical sealing ring 8, the external port of the negative pressure adapter tube 2 is concave relative to the side wall of the sewage tank 92, and the vertical sealing ring 8 is clamped into the concave.
The vertical sealing ring 8 is fixed with the structure communicated with the negative pressure connecting pipe II 2, for example: an annular clamping groove is formed in the outer side of a hole formed in the communication between the clean water tank 91 and the negative pressure connecting pipe II 2, an adaptive clamping ring is formed on one surface of the vertical sealing ring 8, and the clamping ring is clamped into the annular clamping groove and fixed to achieve fixation.
According to the arrangement, after the sewage tank 92 is inserted into the clean water tank 91, the vertical sealing ring 8 ensures that the negative pressure connecting pipe II 2 is in sealing connection with the corresponding hole on the clean water tank 91 so as to avoid that the negative pressure air extraction effect is influenced by air leakage; and because the negative pressure is taken over the mode of wandering of second 2, under the negative pressure effect, can also the port of negative pressure take over second 2 compress tightly on perpendicular sealing washer 8.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
