Description

Technical Field

[0001] This invention relates to the field of cleaning equipment, and in particular to a dry and wet dual-purpose cleaner. Background Technology

[0002] In daily cleaning, sweeping and mopping / wiping are performed separately and independently. Common cleaning appliances are divided into two types: dry cleaners and wet cleaners. Dry cleaners can only perform sweeping in dry or relatively dry environments and are generally only able to clean large-sized dirt (particles larger than 1cm in diameter or length), while they are ineffective at cleaning small particles (particles smaller than 2mm in diameter). Wet cleaners can only perform mopping or wiping in wet environments and are only able to clean small to medium-sized dirt (particles smaller than 1cm in diameter), but they cannot clean large-sized dirt. Therefore, whether a household has a dry cleaner or a wet cleaner, it is necessary to purchase another type of cleaning appliance. This increases the household's purchase cost and space usage, and the frequent switching between the two types of cleaners also results in a poor user experience.

[0003] In view of this, it is necessary to develop a dry and wet cleaning device that combines the functions of both dry and wet cleaners, capable of first sweeping large dirt particles and then mopping / wiping the remaining small dirt particles. Summary of the Invention

[0004] Embodiments of the present invention provide a dual-purpose dry and wet cleaner that combines the functions of both dry and wet cleaners. Users only need to purchase one set of equipment to perform sweeping operations on large-volume dirt first and then mopping / wiping operations on the remaining small-particle dirt. There is no need to frequently switch between sweeping and mopping / wiping operations, which reduces purchase costs and space occupation while improving user experience.

[0005] To address the aforementioned technical problems, embodiments of the present invention disclose the following technical solutions:

[0006] A dual-purpose wet and dry cleaner is provided, including a base, a front cleaning head, and a rear cleaning head. The base has a cleaning chamber, a dry waste collection chamber, a wet waste collection chamber, and a mopping chamber arranged sequentially along the cleaning direction W. The cleaning chamber, dry waste collection chamber, wet waste collection chamber, and mopping chamber are independent of each other and separated from each other. The front cleaning head is rotatably connected to the cleaning chamber laterally, and the rear cleaning head is rotatably connected to the mopping chamber laterally.

[0007] In addition to one or more of the features disclosed above, or alternatively, the post-cleaning head includes:

[0008] Cylindrical rear roller; and

[0009] An absorbent layer is arranged around the outer periphery of the rear roller;

[0010] The absorbent layer is made of an elastic absorbent material.

[0011] In addition to one or more of the features disclosed above, or as an alternative, a water collection channel is provided between the wet waste collection chamber and the mopping chamber, through which the solid-liquid mixture adsorbed and entrained by the rear cleaning head enters the wet waste collection chamber under the action of its own gravity and centrifugal force.

[0012] In addition to one or more of the features disclosed above, or alternatively, the bottom of the water collection channel is configured to have a flow guide slope, wherein one end of the flow guide slope opposite to the rear cleaning head penetrates 0.1 to 0.3 of the thickness of the absorbent layer 131.

[0013] In addition to one or more of the features disclosed above, or as an alternative, the rear cleaning head has a tangential direction opposite to the implementing guide slope, and a guide angle is formed between the extension direction of the guide slope and the tangential direction, the guide angle being 30° to 75°.

[0014] In addition to one or more of the features disclosed above, or as an alternative, a dust-throwing channel is provided between the cleaning chamber and the dry waste collection chamber, through which the waste passing through the front cleaning head is thrown into the dry waste collection chamber under the action of the waste's own gravity and centrifugal force.

[0015] In addition to one or more of the features disclosed above, or alternatively, the front cleaning head includes:

[0016] Cylindrical front roller; and

[0017] At least three radially arranged brush blades are arranged in the circumferential direction of the front roller, and the brush blades extend in a spiral shape around the axis X1 of the front roller;

[0018] Each of the roller brush blades comprises a plurality of radially extending bristles.

[0019] In addition to one or more of the features disclosed above, or as an alternative, a front baffle is arranged around the outer periphery of the front cleaning head; and a rear baffle is arranged around the outer periphery of the rear cleaning head.

[0020] In addition to one or more of the features disclosed above, or as an alternative, the front side of the front baffle is provided with a spray head for spraying cleaning water or cleaning agent.

[0021] In addition to one or more of the features disclosed above, or as an alternative, the front side of the front baffle is provided with at least one lighting lamp.

[0022] One of the above technical solutions has the following advantages or beneficial effects: because it can combine the functions of both dry cleaners and wet cleaners, users only need to purchase one set of equipment to first perform sweeping operations for large-volume dirt and then perform mopping / wiping operations for the remaining small-particle dirt, without having to frequently switch between sweeping and mopping / wiping operations, reducing purchase costs and space occupation while improving user experience.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] refer to Figure 1 and Figure 2 , Figure 1 This is an isometric view of a cleaner 1 that can be implemented according to embodiments of the present invention. The figure shows the main components of the cleaner 1, including a base 11, a front cleaning head 12, and a rear cleaning head 13. Figure 1 In the illustrated embodiment, the base 11 has a cleaning chamber 111, a dry waste collection chamber 112, a wet waste collection chamber 113, and a mopping chamber 114 arranged sequentially along the cleaning direction W (opposite to the forward direction H of the cleaner 1). The cleaning chamber 111, the dry waste collection chamber 112, the wet waste collection chamber 113, and the mopping chamber 114 are independent and separated from each other. The front cleaning head 12 is laterally rotatably connected to the cleaning chamber 111, and the rear cleaning head 13 is laterally rotatably connected to the mopping chamber 114.

[0030] In other embodiments, the top of the base 11 is provided with a connector 15, and the cleaner 1 can be connected to other accessories through the connector 15, such as the handle of the cleaner, the power supply of the cleaner, etc.; at the same time, at least three non-collinearly arranged rollers 1151 are rotatably connected to the bottom of the base 11.

[0031] In practical use, the cleaning mode of the cleaner 1 can be a combined sweeping and mopping type, where the front cleaning head 12 performs the sweeping function and the rear cleaning head 13 performs the mopping function. To further improve cleaning efficiency, a front baffle 122 is usually arranged around the outer periphery of the front cleaning head 12. A spray head 1222a for spraying cleaning water or detergent is provided on the front side of the front baffle 122. Before or during cleaning, the spray head 1222a sprays cleaning water or detergent onto the path to be cleaned. Spraying cleaning water or detergent onto the path to be cleaned can improve cleaning efficiency and sweeping ratio. Figure 3 In the illustrated embodiment, the cleaner 1 has an internal supply pipe 1222b for supplying cleaning agent or cleaning water to the spray head 1222a. In other embodiments, at least one light 1221 is provided on the front side of the front baffle 122. The light can be turned on in a dim environment to illuminate the area to be cleaned, thereby providing visibility to the user and improving the user experience of the cleaning operation.

[0032] The front cleaning head 12 primarily cleans large-volume waste upstream of the cleaning path, such as large dust particles (typically with a particle radius of 2mm or larger), hair, rice grains, and vegetable leaves. A dust-throwing channel 1224 connects the sweeping chamber 111 and the dry waste collection chamber 112. Large-volume waste swept by the front cleaning head 12 is thrown into the dry waste collection chamber 112 through the dust-throwing channel 1224 under the influence of gravity and centrifugal force. The rear cleaning head 13 then cleans downstream of the cleaning path... The front cleaning head 12 removes and absorbs small particles of dirt (usually with a particle radius of less than 2 mm) and solid-liquid mixtures that remain after cleaning. A water collection channel 1131 is provided between the wet waste collection chamber 113 and the mopping chamber 114. The solid-liquid mixture (i.e., sewage, containing small dust particles with a particle radius of less than 2 mm and other soluble dirt) that is absorbed and entrained by the rear cleaning head 13 enters the wet waste collection chamber 113 through the water collection channel 1131 under the action of its own gravity and centrifugal force.

[0033] In a preferred embodiment, the front cleaning head 12 is typically in the form of a roller brush, i.e., it has a generally cylindrical front roller with at least three radially arranged roller brush blades 121 arranged circumferentially. The roller brush blades 121 extend spirally around the axis X1 of the front roller, wherein each roller brush blade 121 includes multiple radially extending bristles. The rear cleaning head 13 is typically in the form of a roller, i.e., it has a generally cylindrical rear roller with a circumferentially arranged absorbent layer 131. The absorbent layer 131 is typically made of an absorbent material with a certain degree of elasticity, such as PVA foam, synthetic fibers, plant fibers, sponges, etc. Regardless of the absorbent material used, the absorbent layer 131 releases the absorbed wastewater after being compressed and contracted. To collect the released wastewater, an extrusion assembly is usually installed in the cleaning channel. The extruded solid-liquid mixture (i.e., wastewater) needs to be guided and collected in a timely manner; otherwise, stains will remain on the cleaned floor, reducing the user experience. Therefore, existing cleaning equipment generally uses a vacuum suction device to draw the extruded solid-liquid mixture into a collection bin for collection. However, cleaners using vacuum suction devices still have the following technical problems during use:

[0034] Although a vacuum suction device is used to guide and collect the extruded solid-liquid mixture, the additional vacuum suction device not only increases the manufacturing cost of the cleaning equipment, but also adds weight, which reduces the user experience. In addition, the vacuum suction device generates a lot of noise when it is working, which further detracts from the user experience.

[0035] To address this, embodiments of this application introduce a dirty water extrusion mechanism for a cleaning head, which can guide and collect the extruded solid-liquid mixture without introducing a vacuum suction device, thereby improving the user experience.

[0036] Reference Figure 2 and Figure 3 , Figure 2 A longitudinal sectional view of a dirty water extrusion mechanism for a cleaning head according to an embodiment of the present invention is shown. The rear cleaning head 13 of the dirty water extrusion mechanism is laterally rotatably connected to the base 11. The rear cleaning head 13 has an imaginary axis of rotation X2 and a longitudinal center plane P. z and the transverse center plane P x The longitudinal center plane P z The transverse center plane P is defined as extending in the vertical direction. x Defined as extending in the horizontal direction, the longitudinal center plane P z With the transverse center plane P xThe axes of rotation X2 are formed by the intersection of the axes, so that the rear cleaning head 13 is imaginarily divided into a first zone 133, a second zone 134, a third zone 135 and a fourth zone 136 in the circumferential direction; a rear baffle 132 is arranged around the outer periphery of the rear cleaning head 13.

[0037] The rear baffle 132 extends circumferentially at least in the first region 133, and the extended section of the rear baffle 132 in the first region 133 is spaced apart from the cleaning head 13 to form a cleaning channel K between the rear baffle 132 and the rear cleaning head 13; an extrusion assembly 14 is arranged in the cleaning channel K. This design allows for the guidance and collection of the extruded solid-liquid mixture without the introduction of a vacuum suction device, thereby reducing the manufacturing cost of the cleaning equipment, reducing the overall weight, and lowering operating noise, thus improving the user experience.

[0038] Refer again Figure 2 The extrusion assembly 14 has a dewatering channel 143, which has the following characteristics:

[0039] The water inlet 1412 is aligned with the rotation direction R of the rear cleaning head 13; and

[0040] The water outlet 1411 is opposite to the rotation direction R of the rear cleaning head 13;

[0041] Wherein, at least one section of the water squeezing channel 143 has a cross-sectional area that gradually decreases in the rotation direction R of the rear cleaning head 13, so that the cross-sectional area of ​​the water outlet 1411 is smaller than the cross-sectional area of ​​the water collection port 1412.

[0042] Furthermore, at least one flow-limiting part 142 is arranged in the water squeezing channel 143, and the flow-limiting part 142 is located between the water collection port 1412 and the water outlet 1411. The flow-limiting part 142 is spaced apart from the side wall 141 of the water squeezing channel 143 and is adjacent to the water outlet 1411, so that the water flow in the water squeezing channel 143 is divided into at least two streams by the flow-limiting part 142 and then converges at the water outlet 1411. This enables the squeezed solid-liquid mixture to be gathered, facilitating subsequent guidance and collection.

[0043] Reference Figure 3 At least one flow restrictor 142 is aligned with the outlet 1411, defined as follows:

[0044] The distance between the flow restrictor 142 and the side wall 141 of the squeezing channel 143 is d; and

[0045] The dimension of the outlet 1411 in the direction of the rotation axis X2 is D; therefore, 2.5d ≤ D ≤ 6d. Figure 3In the illustrated embodiment, there may be only one flow restrictor 142, where D = 6d. In other embodiments, a filter screen is also arranged between the flow restrictor 142 and the sidewall 141 of the squeezing channel 143.

[0046] Furthermore, to facilitate the installation and cleaning of the squeezing channel 143, the rear baffle 132 can be designed to be removed from the base 11, and the sidewall 141 and flow-limiting portion 142 of the squeezing channel 143 are connected to the baffle 132 at their respective tops. In another embodiment, the sidewall 141 of the squeezing channel 143 is connected to the base 11 at its side, and the flow-limiting portion 142 is connected to the baffle 132 at its top.

[0047] To better expel wastewater from the rear cleaning head 13, the sidewall 141 is configured to at least partially penetrate the absorbent layer 131 of the cleaning head 13. In a preferred embodiment, the penetration amount of the sidewall 141 is 0.05 to 0.2 times the thickness of the absorbent layer 131.

[0048] Furthermore, to prevent backflow of squeezed-out wastewater, the outlet 1411 cannot be located near the top of the rear cleaning head 13. Define the line connecting the outlet 1411 and the rotation center of the cleaning head 13 as the outlet positioning line 144. Then, the outlet positioning line 144 and the longitudinal center plane P... z A positioning angle α is formed between them, the magnitude of which is 30° to 75°. In a preferred embodiment, the magnitude of the positioning angle α is 75°. In other embodiments, the rear baffle 132 extends from the end of the sprue positioning line 144 across the longitudinal center plane P. z Extending to zone 134 and terminating at the said transverse center plane P x The gap between the rear baffle 132 in the second zone 134 and the water-absorbing layer 131 is 1-5 mm.

[0049] In a preferred embodiment, the cleaner 1 has a centerline Y in the front-to-back direction, and the outlet 1411 is arranged near the centerline Y. Furthermore, to better collect the squeezed-out wastewater, the water collection channel 1131 can be configured as follows: Figure 2 The location shown is downstream of outlet 1411. (Refer to...) Figure 1In another embodiment, the bottom of the water collection channel 1131 is configured with a guide slope U, wherein the guide slope U and the opposite end of the rear cleaning head 13 penetrate 0.1 to 0.3 times the thickness of the absorbent layer 131, thereby further squeezing the absorbent layer 131 to release residual moisture. Furthermore, the opposite end of the rear cleaning head 13 and the guide slope U has a tangential direction S, and a guide angle is formed between the extending direction of the guide slope U and the tangential direction S, the size of which is 30° to 75°. In a preferred embodiment, the size of the guide angle is 60°.
