Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning machines, in particular to a peculiar smell preventing cleaning roller mechanism and a cleaning appliance. BACKGROUND

[0002] With the progress of science and technology, people's requirements for floor cleaning tools have gradually increased. A new cleaning mechanism has emerged, which uses a cleaning roller to adsorb dust on the cleaning surface, and then uses water to wash the cleaning roller to remove the dust from the cleaning roller. This mechanism is called "water dust circulation". Cleaning appliances using this mechanism are also called "water dust circulation" scrubbers. The water dust circulation scrubber drives the cleaning cylinder to wipe the floor through the operation of the motor. The cleaning cylinder usually adopts a sponge cylinder structure. At the same time, the floor cleaning appliance is also equipped with a water supply system to clean the cleaning cylinder, thereby perfectly achieving the cleaning of the floor.

[0058] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0059] The following will describe the scheme of this application in detail with reference to the accompanying drawings. Example

[0060] like Figures 1-3 As shown, the present invention provides an odor-proof cleaning roller mechanism, which includes a cleaning roller 1 and a roller cover 2, and further includes a wringing strip 3 and a water guiding strip that form a cleaning surface in contact with the surface of the cleaning roller. A receiving baffle 4 is provided on the outside of the wringing strip that contacts the surface of the cleaning roller. One end of the receiving baffle 4 is movably connected to the wringing strip 3. The receiving baffle 4 can achieve a smooth connection with the wringing part 31 of the wringing strip 3. In this way, the fine particles separated from the surface of the cleaning roller during the wringing process are carried away under certain interference between the receiving baffle 4 and the cleaning roller, thereby preventing their accumulation and the generation of odor.

[0061] To improve the stability of the receiving baffle 4 during operation, the other end of the receiving baffle 4 is movably connected to the roller cover plate 2. A fixing member 5 for connecting and fixing the squeezing strip 3 is provided between the roller cover plate 2 and the receiving baffle 4. The fixing member 5 includes a fixed end and a free end, wherein the fixed end is movably connected to the cleaning head housing 6 and the squeezing strip 3, and the free end is connected to the receiving baffle 4.

[0062] The squeezing strip 3 includes a first fixing part 30, which abuts against the other end face of the fixing member 5 away from the cleaning head housing 6. A fixing groove 50 is provided on the abutting surface of the fixing member 5. A second fixing part 32 of the squeezing strip 3 is engaged in the fixing groove 50, thereby achieving the connection and fixation between the squeezing strip 3 and the fixing member 5. The first fixing part 30 is used to prevent the squeezing strip 3 from rotating under force, and the second fixing part 32 is used to connect with the fixing member 5. The squeezing strip 3 also includes a squeezing part 31 that interferes with the roller surface and a filter part 33 located at the front end of the squeezing part. The filter part 33 has multiple filter holes 35 for wastewater to flow out. In this embodiment, the number and distribution rules of the filter holes 35 are not limited and can be set as needed. For example, the filter holes 35 can be regularly distributed or staggered. Preferably, the filter part 33 is in contact with the roller surface, which ensures that the wastewater squeezed out of the roller by the squeezing strip 3 can pass through the filter holes 35 during use.

[0063] In order to prevent the water from overflowing after flowing through the filter hole 35, and to prevent the cleaning roller surface from being too wet to form water on the ground, a water baffle 34 is arranged on the filter part 33, and a deposition groove 36 for depositing fine particles is formed between the water baffle 34 and the filter part 33, which can prevent fine particles from entering the sewage discharge pipeline and causing easy blockage. In order to prevent the water flowing into the deposition groove 36 from flowing back into the filter hole 35, a certain interval distance is maintained between the bottom of the deposition groove 36 and the filter hole 35.

[0064] In order to reduce the resistance of the connecting baffle 4 to the surface of the cleaning roller, the connecting baffle 4 is movably connected with the water squeezing strip 3, and the water squeezing strip 3 is provided with a mounting groove 38 which is clamped and fixed with a fixed part 42. After the fixed part 42 is clamped into the mounting groove 38, the connecting baffle 4 and the water squeezing strip 3 are fixed. The mounting groove 38 is provided with a slot and a mounting cavity, and the width of the slot is smaller than the maximum distance between the walls of the mounting cavity. The cross section of the mounting groove 38 is preferably circular, which can ensure a certain amount of rotation after the water squeezing strip 3 is installed, thereby reducing the resistance generated.

[0065] As a variant design of this embodiment, as shown in Figure 4 In order to give the connecting baffle 4 greater rebound effect and deformation space, a plurality of variable cavities 40 divided by elastic pressing strips 49 are arranged between the connecting baffle 4 and the fixing part 5. In order to achieve a better rebound effect, the elastic pressing strips 49 are vertically spaced apart in a horizontal plane with the ground as the horizontal line.

[0066] The design of the elastic pressing strip 49 can provide the connecting baffle 4 with greater deformation space, while reducing the stress on the cleaning roller. When an external force is transmitted to the fixing part 5 through the roller cover plate 2, the external force on the water squeezing strip 5 can be effectively dispersed due to the design of the elastic pressing strip 49, so as not to affect the normal work of the cleaning roller.

[0067] In order to facilitate the cooperation with the free end of the fixing part, as shown in Figure 1 、 Figure 3 、 Figure 4 The end of the connecting baffle 4 connected with the free end of the fixing part 5 is provided with an elastic stretchable hook part 43 which is sleeved on the free end of the fixing part 5, so as to realize the connection and fixation of the connecting baffle 4 and the fixing part 5, and keep the interference between the connecting baffle 4 and the roller within a certain range, so that the resistance between the connecting baffle 4 and the roller is appropriate.

[0068] In specific operation, as shown in Figure 1 、 Figure 2As shown, the fixed part 42 can be first clamped in the installation slot 38, then the water squeezing strip 3 is connected with the fixing part 5 through the second fixed part 32 and the first fixed part 30 prevents rotation, and the hook part 43 on the connecting and blocking plate can be sleeved on the free end of the fixing part. Of course, the fixing part can be first connected with the water squeezing strip, then the connecting and blocking plate is connected with the water squeezing strip, and then the free end of the fixing part is sleeved on the hook part. The above-mentioned two different operation modes are only two different operation modes, and of course, the operation mode can be selected according to the operation habit of the person.

[0069] In order to enable the connecting and blocking plate 4 to smoothly separate the garbage such as debris from the surface of the cleaning roller after being squeezed by the water squeezing strip 3, the connecting and blocking plate is designed as an arc shape which is adapted to the surface of the cleaning roller. Because the cleaning roller will have a certain elasticity after absorbing water, in order to prevent the connecting and blocking plate from scratching the cleaning roller when the connecting and blocking plate is in contact with the surface of the cleaning roller, the connecting and blocking plate is made of an elastic material, and preferably, the elastic material is rubber.

[0070] In this embodiment, there is a small height difference between the connecting and blocking plate and the water squeezing part 31 of the water squeezing strip, and when the connecting and blocking plate is in contact with the surface of the cleaning roller after being squeezed by the water squeezing strip, the garbage such as debris generated from the surface of the cleaning roller after being squeezed will not be accumulated in the form of fine particles at the rear end of the water squeezing strip, thereby reducing the odor generated from the cleaning roller mechanism.

[0071] As shown in the figure, Figures 9-12 The connecting and blocking plate 4 includes a connecting and blocking plate body 45, a plurality of reinforcing ribs 46 are distributed on the surface of the connecting and blocking plate body, a plurality of fixing buckles 47 are arranged between the reinforcing ribs, a plurality of fixing holes 51 corresponding to the fixing buckles 47 are arranged on the fixing part 5, and a fixing sliding groove 52 is arranged in the fixing hole 51 in order to facilitate the connection and fixing of the fixing buckle 57 and the fixing hole 51. Figure 9 As shown in the figure, The fixing buckle is designed as a structure with a wide upper part and a narrow lower part, and a chamfer is arranged at the transition area between the wide part and the narrow part, and the corresponding fixing sliding groove is designed as a structure which is adapted to the fixing buckle, thereby facilitating the stable cooperation between the fixing buckle and the fixing hole and facilitating the assembly and fixing of the fixing buckle and the fixing hole.

[0072] In this embodiment, the structure of the fixing buckle is not limited to the structure shown in the figure, and can be a clamping hook or any other structure which can be connected and fixed with the fixing hole and is not easy to fall off.

[0073] In the existing product mechanism, Figure 1 , Figure 3 , Figure 4As shown, when the water flow through the filter hole 35 is too large, the water is easy to overflow the wringing strip along the back plate of the wringing strip and drip along the cleaner head housing to the floor, or drip down along the cleaner head housing to form water accumulation on the ground, which not only affects the cleaning effect of the cleaning appliance but also causes a bad experience for the customer. At the same time, fine particle garbage along the water flow is easy to accumulate on the cleaner head housing, thereby causing odor.

[0074] To solve the above technical problems, the specific embodiment is that the hook portion cooperates with the free end of the fixing member, so as to ensure that the water overflowing the wringing strip always stays between the guide baffle and the fixing member. When the water flows through the drain hole 48, the water flow passes through the drain hole to the surface of the cleaning roller because the drain hole is in contact with the surface of the cleaning roller. The cleaning roller is made of soft and water-absorbing material, which can quickly absorb the water dripping through the drain hole, thereby solving the technical problem of water dripping directly along the cleaner head housing to the ground.

[0075] As shown in Figure 1 , Figure 3 , Figure 4 In the embodiment, the guide baffle is detachably connected with the wringing strip. When fine particle garbage in the water flow adheres to the guide baffle body or the hook portion, the guide baffle can be disassembled and washed, thereby effectively preventing odor caused by long-term accumulation of fine particle garbage.

[0076] As shown in Figure 9 , Figure 10 In the embodiment, the number of the fixing buckles is a plurality, and the number of the drain holes 48 is one less than the number of the fixing buckles. For example, when the number of the fixing buckles is 6, the number of the drain holes 48 is 5, and the drain holes 48 are respectively distributed between the corresponding two fixing buckles. Of course, the drain holes can also be arranged between the reinforcing ribs, and at this time, the water flow can pass along the reinforcing ribs and directly flow out through the drain holes.

[0077] In the embodiment, the drain holes are preferably arranged in one row, and of course, they can also be arranged in multiple rows or multiple columns in a staggered manner, as long as they can facilitate the water flow to quickly flow out through the drain holes.

[0078] In the embodiment, the height difference between the guide baffle and the wringing portion of the wringing strip is small or flush, so that fine particle garbage cannot accumulate at the rear end of the wringing strip, thereby reducing odor generated by the cleaning roller mechanism. At the same time, the hook portion, the fixing buckle, the fixing hole and the drain hole structure designed on the guide baffle can effectively prevent the water from overflowing the wringing strip and dripping along the cleaner head housing, and also avoid the fine particle garbage along the water flow from accumulating on the cleaner head housing, thereby reducing odor generated by the cleaning roller mechanism. Embodiment

[0079] As shown in Figure 5As shown, the embodiment is different from embodiment one, in this embodiment, the fixed plate and the guide baffle are detachably connected, in this scheme, the connection is mainly realized by the screw, of course, the connection mode of the two in this embodiment is not limited, as long as the detachable connection mode in the art can be used as an alternative scheme in this embodiment. In order to realize the seamless connection between the guide baffle and the water squeezing strip, the guide baffle and the water squeezing strip are connected by adhesion in this embodiment. Through the above two connection modes, the seamless connection of the guide baffle and the water squeezing strip can be realized, and at the same time, the small height difference or the nearly flush between the guide baffle and the water squeezing strip is realized.

[0080] Another difference compared with embodiment one is that: there is no elastic pressing strip structure design in this embodiment, but the inside of the guide baffle can still be designed as a variable cavity structure, the other end of the guide baffle away from the water squeezing strip is free to abut against the cleaning roller, or a protrusion can also be provided at the end face of the other end, the protrusion abuts against the fixing part, when the fixing part deforms, the protrusion structure design can achieve a certain buffering effect, thereby reducing the force between the guide baffle and the cleaning roller, and ensuring the normal work of the cleaning roller.

[0081] Similarly, the free end of the fixing part abuts against the protruding part of the guide baffle, giving it more space for movement and deformation, and other structures are the same as those in embodiment one, which will not be repeated here.

[0082] The above design can also meet the requirements that: when in use, the guide baffle contacts the surface of the cleaning roller after being squeezed by the water squeezing strip, and separates the garbage such as debris generated after being squeezed from the surface of the cleaning roller. Because there is a small height difference or nearly flush between the guide baffle and the water squeezing strip in this embodiment, fine particle garbage will not be accumulated at the rear end of the water squeezing strip, reducing the odor of the cleaning roller mechanism. Embodiment

[0083] As Figures 6-8 : The embodiment is different from embodiment one and embodiment two, the guide baffle comprises a limiting part 41, which is a protruding structure, in this scheme, the end face of the protruding structure is arc-shaped, the arc-shaped protruding end face of the limiting part abuts against the fixing part, in this embodiment, the arc-shaped protruding end face of the limiting part abuts against the middle part of the fixing part, that is, the length of the fixing part is the length between the free end and the fixed end, and the fixed end is the abutting end of the fixing part abutting against the first fixed part and close to the free end.

[0084] At the same time, in this embodiment, the end face of the guide baffle and the water squeezing part 31 of the water squeezing strip are flush, the water squeezing part is provided with a guide part 37, the guide part is flush and smoothly connected with the guide baffle, and the guide baffle is provided with a fixed part 42 matched with the guide part.

[0085] In order to achieve the effect of flush end surface, one end of the guide part connected with the water squeezing part is a fixed end, and the other end is a free end. The end surface of the free end in contact with the surface of the cleaning roller forms a certain angle with the end surface of the fixed groove. In the present scheme, the angle is preferably an acute angle. Correspondingly, a flush end 44 is arranged on the connecting guide baffle. When the fixed part is clamped into the fixed groove, the flush end is just connected with the angle of the guide part, so as to realize the smooth connection of the connecting guide baffle and the water squeezing strip.

[0086] Because the cleaning roller has a certain elasticity after being contacted with water, in order to prevent the garbage from being left on the pressing part of the surface of the cleaning roller during the working process of the connecting guide baffle and the water squeezing strip, the end surface of the water squeezing part of the connecting guide baffle and the water squeezing strip is flush. When in use, the fine particle garbage formed at the rear end of the water squeezing strip will fall along with the roller and be recycled again, so as to reduce the accumulation of garbage. This design can reduce the garbage left in the cleaning roller mechanism and reduce the odor of the cleaning roller mechanism.

[0087] According to the embodiment of the present application, a cleaning appliance is provided, which comprises the above cleaning roller mechanism.

[0088] In addition, the cleaning appliance further comprises a cleaning head shell 6 and the like.

[0089] According to the embodiment of the present application, during the working process of the cleaning appliance, the cleaning roller rotates, the garbage is rolled up by the cleaning roller, and the clean water is delivered to the surface of the cleaning roller to flush the cleaning roller. The water squeezing strip is installed on the upper part of the cleaning head shell, and the water squeezing strip and the cleaning roller are in interference fit. The sewage squeezed out of the water squeezing strip and the clean water delivered to the cleaning roller are mixed together, and a part of the garbage is taken away by the water flow. The part of the cleaning roller rotating through the water squeezing part of the water squeezing strip is restored to the normal surface shape without pressure under the elasticity of the material of the cleaning roller itself. The connecting guide baffle just absorbs the impact generated during the shape restoration of the part of the cleaning roller surface. The part of the cleaning roller surface during the shape restoration cannot throw out the "micro-particle" garbage mixed in the "clean surface" after "water squeezing". Naturally, these thrown out "micro-particle" garbage cannot be deposited on the lower surface corresponding to the part of the cleaning roller surface without the connecting guide baffle. The cleaning appliance can be widely used on the cleaning appliance, which can be a dust collector, a floor washing machine or a sweeping robot product.

[0090] The above has carried out the detailed introduction to the embodiment of the application, the principle and implementation mode of the application have been described by applying specific examples in this paper, the above embodiment description is only used for helping understanding the method of the application and its core idea. At the same time, the changes or deformations made by the person skilled in the art on the basis of the specific implementation mode and the application range of the application according to the idea of the application all belong to the protection scope of the application. In summary, the content of the specification should not be understood as the limitation of the application.
