[0002] As people's living standards continue to improve, cleaning machines such as floor scrubbers, vacuum cleaners or sweepers have been widely used in people's daily lives. As a floor cleaning device, a cleaning machine can suck a mixture of dust mixed with water vapor on the floor into its storage chamber. When the floor needs to be cleaned, the user can hold the cleaning machine and sweep and mop the floor where the cleaning machine passes, thereby achieving the purpose of floor cleaning.

[0003] Cleaning machines are usually equipped with a charging stand to improve their battery life. When the battery life of the cleaning machine itself is insufficient, it can be moved to the charging stand for charging. For details, please refer to the Chinese patent application number CN202221978250.9 "A charging stand and a floor scrubber having the same".

[0004] However, for traditional charging stands, on the one hand, the charging contacts are directly installed on the charging base, and the assembly structure is complex, which greatly reduces the assembly efficiency of the whole machine; on the other hand, the charging contacts will have poor contact with the charging part of the cleaning machine body during long-term use, and the reliability is poor. Summary of the invention

[0005] The first technical problem to be solved by the present invention is to provide a charging stand for a cleaning machine that can improve assembly efficiency in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a charging stand for a cleaning machine which can improve charging reliability.

[0007] The third technical problem to be solved by the present invention is to provide a cleaning machine using the above-mentioned charging stand.

[0008] The technical solution adopted by the present invention to solve the above-mentioned first and second technical problems is: a charging stand for a cleaning machine, comprising

[0009] A seat body, used for placing the cleaning machine body; and

[0010] A charging module, disposed on the base, for supplying power to the cleaning machine body;

[0011] The feature is that: the rear part of the seat body is provided with a mounting box with its opening facing downwards, and the side walls on the left and right sides of the mounting box are provided with limiting holes;

[0012] The charging module is installed in the installation box and includes

[0013] Fixed seat;

[0014] Two movable blocks corresponding to the limiting holes, each of the movable blocks being slidably mounted on the fixing seat, and having a charging contact mounted on its head; and

[0015] Two elastic members corresponding to the movable block, each of the elastic members acting between the fixed seat and the corresponding movable block, so that the movable block always has a tendency to move toward the corresponding limiting hole;

[0016] In the locked state, the movable block is inserted into the corresponding limiting hole, and its head extends out of the installation box;

[0017] In the unlocked state, the movable block is retracted into the installation box to allow the charging module to be separated from the installation box from the opening at the bottom of the installation box.

[0018] In order to facilitate the installation of the movable block, the fixing seat is a hollow shell, and the side walls on the left and right sides are provided with through holes corresponding to the limiting holes. Each movable block can be slidably inserted into the corresponding through holes.

[0019] In order to prevent the movable block from interfering with the edge of the limiting hole during its left and right sliding movement and affecting its smooth movement, the width of the assembly gap formed between the movable block and the through hole is recorded as W1, and the width of the assembly gap formed between the movable block and the limiting hole is recorded as W2, W1<W2.

[0020] In order to expand the effective contact surface between the movable block and the fixed seat and ensure smooth movement of the movable block 22, the edge of each perforation is bent and extended outward to form a convex edge.

[0021] In order to ensure the stable sliding and limiting of the movable block, a slider is protruding on the peripheral wall of the tail of each movable block, and the interior of the fixed seat has a sliding groove corresponding to the slider and extending in the left and right directions. Each slider can be slidably accommodated in the sliding groove.

[0022] In order to avoid installation errors in the upper and lower directions of the movable blocks, each movable block corresponds to at least two sliders, which are respectively recorded as a first slider and a second slider, and the first slider and the second slider are respectively located at the front and rear sides of the movable block;

[0023] The sliding groove corresponding to the first slider is recorded as a first sliding groove, and the width of the first sliding groove matches the width of the first slider; the sliding groove corresponding to the second slider is recorded as a second sliding groove, and the width of the second sliding groove matches the width of the second slider;

[0024] The widths of the first sliding groove and the second sliding groove are inconsistent.

[0025] In order to facilitate the installation of the elastic member, a mounting seat is provided inside the fixing seat at a position between the two through holes, and the left and right sides of the mounting seat have first mounting grooves corresponding to the elastic member, and each of the movable blocks has a second mounting groove with an opening facing the mounting seat;

[0026] Each of the elastic members is a spring and is located in the fixing seat. Two ends of each spring are respectively accommodated in the corresponding first installation groove and second installation groove.

[0027] In order to facilitate the mold opening and installation of the fixing seat, the fixing seat includes a top cover and a base that are matched and connected up and down, and an inner cavity of the fixing seat is formed between the top cover and the base.

[0028] In order to facilitate charging of the charging module, the charging module also includes a charging socket, which is installed on the fixing seat and electrically connected to each of the charging contacts through a wire. The installation box is provided with a clearance hole set for the charging socket.

[0029] In order to facilitate the assembly guidance and charging guidance of the charging module, the edge of the head of each movable block is chamfered.

[0030] In order to facilitate the charging module to enter and exit the installation box, the diameter of the inner cavity of the installation box gradually decreases from top to bottom.

[0031] In order to facilitate the processing of the installation box, the surface of the seat body has a receiving groove for placing the cleaning machine body, the inner wall of the rear part of the receiving groove has a notch, and the edge of the bottom of the installation box is connected to the edge of the notch.

[0032] The technical solution adopted by the present invention to solve the third technical problem is: a cleaning machine using the above-mentioned charging stand.

[0033] Compared with the prior art, the advantages of the present invention are: a charging module composed of a fixed seat, a movable block and an elastic member is installed in an installation box; in a locked state, the movable block is inserted in the limiting hole of the installation box, and its head extends out of the installation box to allow the charging contacts to contact and charge with the charging part of the cleaning machine body; in an unlocked state, the movable block is retracted into the installation box to allow the charging module to detach from the installation box from the opening at the bottom of the installation box. In this way, on the one hand, the charging module is detachably installed through a snap-on structure, which can improve assembly efficiency, and the modular design facilitates its replacement and reuse; on the other hand, during the charging process, the charging contacts at the head of the movable block can be tightly pressed against the charging part of the cleaning machine body under the elastic force of the elastic member, thereby ensuring good contact between the two and greatly improving the charging reliability.

[0041] The present invention is further described in detail below with reference to the accompanying drawings.

[0042] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0043] like Figures 1 to 7 As shown, a preferred embodiment of the present invention is a cleaning machine with a charging base. The cleaning machine can be a floor scrubber, a vacuum cleaner, or a sweeper, etc. This embodiment is described by taking a floor scrubber as an example. The floor scrubber includes a cleaning machine body and a charging base. In this embodiment, the charging base includes a base body 1 and a charging module 2.

[0044] The seat 1 is used to place the cleaning machine body. Specifically, the surface of the seat 1 has a receiving groove 11 for placing the cleaning machine body, and the inner wall of the rear part of the receiving groove 11 has a notch 111. The notch 111 is provided with a mounting box 12 with an opening facing downward, and the edge of the bottom of the mounting box 12 is connected to the edge of the notch 111. The side walls on the left and right sides of the mounting box 12 are provided with limiting holes 121, and the rear side wall of the mounting box 12 is provided with a clearance hole 122. In this embodiment, the diameter of the inner cavity of the mounting box 12 gradually decreases from top to bottom.

[0045] The charging module 2 can be detachably installed in the installation box 12 to supply power to the cleaning machine body. In this embodiment, the charging module 2 includes a fixing seat 21 , a movable block 22 , an elastic member 23 and a charging socket 24 .

[0046] Specifically, the fixing seat 21 is a hollow shell, including a top cover 21a and a base 21b connected in a matching manner, and the top cover 21a and the base 21b surround an inner cavity of the fixing seat 21. The side walls on the left and right sides of the fixing seat 21 are provided with through holes 211 corresponding to the above-mentioned limiting holes 121; the inside of the fixing seat 21 has a slide groove 212 corresponding to the slider 222 described below and extending in the left and right directions; the inside of the fixing seat 21 is provided with a mounting seat 213 located between the two through holes 211, and the left and right sides of the mounting seat 213 have first mounting grooves 2131 corresponding to the through holes 211.

[0047] There are two movable blocks 22, corresponding to the above-mentioned through holes 211. Each movable block 22 can be slidably inserted into the corresponding through hole 211; a charging contact 221 is installed on the head of each movable block 22, and the edge of the head has a chamfer; a slider 222 is convexly provided on the peripheral wall of the front side, rear side, top side and bottom side of the tail of each movable block 22, and each slider 222 can be slidably accommodated in the corresponding slide groove 212; each movable block 22 has a second mounting groove 223 with an opening facing the mounting seat 213.

[0048] There are two elastic members 23, corresponding to the above-mentioned movable blocks 22. Each elastic member 23 is a spring and is located in the fixing seat 21. The two ends of each spring are respectively accommodated in the corresponding first installation groove 2131 and the second installation groove 223, so that the movable block 22 always has a tendency to move toward the corresponding limit hole 121.

[0049] The charging socket 24 is installed at the rear of the inner cavity of the fixing seat 21 and is directly opposite to the above-mentioned clearance hole 122. The charging socket 24 is electrically connected to each charging contact 221 through a wire 241.

[0050] In the locked state, Figure 3As shown, the movable block 22 is inserted into the corresponding limiting hole 121, and its head extends out of the mounting box 12 to allow the charging contact 221 to contact and charge the charging part of the cleaning machine body;

[0051] In the unlocked state, Figure 4 As shown, the movable block 22 is retracted into the installation box 12 to allow the charging module 2 to be separated from the installation box 12 through the opening at the bottom of the installation box 12 .

[0052] In addition, in order to avoid the jamming of the movable block 22 and thus ensure the charging reliability of the charging contact 221, on the one hand, the width of the assembly gap formed between the movable block 22 and the through hole 211 is recorded as W1, and the width of the assembly gap formed between the movable block 22 and the limiting hole 121 is recorded as W2, W1<W2, thereby avoiding the interference between the movable block 22 and the edge of the limiting hole 121 during the left and right sliding process and affecting its smooth movement; the edges of each through hole 211 are bent and extended outward to form a convex edge 2111, thereby expanding the effective contact surface between the movable block 22 and the fixed seat 21, thereby ensuring the smooth movement of the movable block 22.

[0053] Since the two movable blocks 22 have the same features, in order to avoid incorrect installation in the up and down directions (reverse installation), the sliders 222 on the front and rear sides of the movable block 22 are respectively recorded as the first slider 222a and the second slider 222b, and the slide groove 212 corresponding to the first slider 222a is recorded as the first slide groove 212a, and the width of the first slide groove 212a matches the width of the first slider 222a, and the slide groove 212 corresponding to the second slider 222b is recorded as the second slide groove 212b, and the width of the second slide groove 212b matches the width of the second slider 222b. The widths of the first slide groove 212a and the second slide groove 212b are inconsistent. In this way, when the movable block 22 is installed incorrectly, it will interfere with the fixed seat 21.

[0054] The working principle of this embodiment is as follows:

[0055] (1) During installation, first press the movable block 22 inward, and then align the entire charging module 2 with the opening at the bottom of the installation box 12 and insert it upward. During the insertion process, the head of the movable block 22 is pressed so that it remains in a retracted state until the movable block 22 moves to a position directly opposite the limiting hole 121. Under the elastic force of the elastic member 23, it is inserted into the corresponding limiting hole 121 to be locked, and its head protrudes out of the installation box 12. At this time, Figure 3As shown, the charging module 2 is in a locked state, so that when the cleaning machine body is placed in place in the receiving groove 11, the charging contact 221 will contact the charging part of the cleaning machine body for charging. It is worth noting that during the charging process, the movable block 22 is slightly retracted under pressure, and the charging contact 221 at its head is tightly pressed against the charging part of the cleaning machine body under the elastic force of the elastic member 23, thereby ensuring good contact between the two and greatly improving the charging reliability;

[0056] (2) When disassembling, first press the movable block 22 inward until it retracts into the mounting box 12. Figure 4 As shown, the charging module 2 is in an unlocked state, and then the entire charging module 2 is moved downward and taken out through the opening at the bottom of the installation box 12 to achieve disassembly of the charging module 2.
