Description

Floor brush module for cleaning machine and cleaning machine

Technical Field

The invention relates to the field of household cleaning tools, in particular to a floor brush module for a cleaning machine and the cleaning machine.

Background

With the development of household cleaning technology, household cleaning devices are gradually diversified, and more cleaning devices enter thousands of households. The traditional dust collector has certain use limit, and the structural design and the tightness of parts of the traditional dust collector can only meet the use scene of a dry environment, but cannot be used in a wet environment; when the motor is in a wet environment, sewage carried by dust collection airflow can be inevitably permeated to the motor under the action of negative pressure, and once the water enters the motor through a gap of a shell at the motor, the motor is easily damaged due to failure.

Obviously, the cleaning machine which only can collect dust but cannot absorb water can not meet the use requirements of consumers, and for this purpose, a part of enterprises develop a floor cleaning machine which can be used in both dry and wet environments, and especially the dust collecting barrel part of the floor cleaning machine is improved to a certain extent, so that dry and wet garbage can be separated better, and water is prevented from flowing to a negative pressure source. For example, chinese patent application No. CN202010568160.1 (published: CN111820816 a) discloses a water machine dry-wet dual-purpose sewage tank assembly, a sewage inlet pipe is disposed at the bottom of the sewage tank, the filter assembly is disposed inside the sewage tank and is sleeved on the sewage inlet pipe, the tank cover assembly is mounted on the sewage tank, after the mixed fluid passes through the sewage tank, the liquid and the solid remain in the sewage tank, the air flow continues to flow toward the downstream negative pressure source, an air outlet is formed at the end of the air path of the floor washing machine, i.e. the housing of the air machine module of the floor washing machine, the air flow sucked by the negative pressure is finally discharged from the air outlet, but only the negative pressure source is used as the main acting force of dust collection, and the water sprayed on the surface to be cleaned is sucked by the negative pressure only after one to two times of use due to the rotation form of the rolling brush itself, and the cleaning effect is relatively limited.

For this reason, the applicant has made a certain improvement to the conventional rolling brush cleaning mode, and has proposed another cleaning mode, and in chinese application publication No. CN201911094051.4 (publication No. CN 112773255A), an integrated structure for cleaning object surface is disclosed, which is provided with a brush in a dust collection cylinder, the brush being rotatable in an inner axial direction of the dust collection cylinder, i.e., a rotation axis thereof is vertically extended unlike a horizontal arrangement of the conventional rolling brush. The brush arrangement form can enhance the flow field of the central area of the fluid by cleaning the ground with the brush hair when in work, and can reduce the dirt residue in the central area by matching with the cleaning liquid, thereby avoiding the situation that the water cleaning capacity is sucked away by negative pressure after being used for a small number of times in the rolling brush mode, and meeting the requirement of heavy cleaning in a wet environment.

Although the dust collecting device is improved against the defects of the rolling brush, as the brush has a certain height, the gain of the brush to the air flow needs to be met when the dust collecting device is cleaned, the dust collecting device is arranged on a flow path of the fluid, the air exhaust position is arranged at the upper end of the dust collection cylinder so as to not influence the output of the fluid, and the air inlet position is arranged at the lower end of the dust collection cylinder so as to facilitate dust collection, so that a certain longitudinal depth of an inner cavity of the dust collection cylinder needs to be formed when the dust collection cylinder is designed, namely, a three-dimensional cyclone is formed, and after the negative pressure fluid which is wrapped with dust particles is sucked into the dust collection cylinder, the dust collection cylinder needs to be displaced vertically for a long distance.

This has various disadvantages, more obvious aspects are:

1. because the flowing direction of the fluid is from front to back and is consistent with the moving direction of the cleaner when the fluid is cleaned, most dirt enters and is discharged at least twice after entering the dust collection cylinder, and the fluid and the entrained solid particles impact on the inner wall of the dust collection cylinder when turning, so that the noise decibel is greatly increased;

2. in order to install the brush and other parts in the dust collection cylinder, an irregular shell part is formed, and under the holding of dry and wet environments, the long-distance flow guide makes the positions become dirt-collecting positions and extremely difficult to clean, and the use experience is to be improved;

3. the fluid moving path is longer, and the suction force of the negative pressure source is damaged.

Detailed Description

The invention is described in further detail below with reference to the embodiments of the drawings.

As shown in fig. 1 to 18, which are a preferred embodiment of the present invention, in this embodiment, the floor brush module is used in a cleaning machine, and the cleaning machine further includes a separation module 02 for separating a fluid and a blower module 03 for providing a negative pressure source, the floor brush module 01, the separation module 02 and the blower module 03 are sequentially arranged along a flow path of the fluid, wherein the floor brush module includes a housing 1 and a brush 5, the housing 1 has an air inlet 1b and an air outlet 1d, the air inlet 1b is located upstream of the air outlet 1d along the flow path of the fluid, an inlet end of the separation module 02 is in fluid communication with the air outlet 1d, and an outlet end of the separation module 02 is in fluid communication with an inlet end of the blower module 03.

For the purpose of negative pressure cleaning, the housing 1 has a vertically extending mounting hole 17, a flow channel 100 extending back and forth is formed between the lower edge of the mounting hole 17 and the surface 102 to be cleaned, the air inlet 1b and the air outlet 1d are both communicated with the flow channel 100, and the direction of fluid flowing in the flow channel 100 intersects with the extending direction of the mounting hole 17. The fluid flow direction referred to herein means that the air flow in all directions in the flow channel 100 can be maintained to flow through the flow channel 100 in a substantially horizontal area, and since the mounting holes 17 are vertically extended, it is understood that the extending direction of the mounting holes 17 is perpendicular to (i.e., intersects) the horizontal area through which the air flow flows. Specifically, the bottom wall of the housing 1 has a circumferential wall 18 at the periphery corresponding to the lower edge of the mounting hole 17, and the air inlet 1b and the air outlet 1d are both formed on the circumferential wall 18, where the air inlet and the air outlet may be arranged through along the extending direction of the flow channel 100, so that the loss of suction force can be reduced, but in this embodiment, in order to facilitate forming a planar cyclone, so that the fluid has a better brushing force, the air inlet 1b and the air outlet 1d are both formed on the side of the circumferential wall 18 along the travelling direction of the floor brush module. The annular wall 18 can be formed in different forms, and the annular wall 18 in the embodiment is formed by extending downwards from the bottom wall of the shell 1, and is directly formed by integral molding during production, so that the accumulation of dirt at a gap during use can be avoided.

In addition to the negative pressure cleaning function, the cleaning machine can also provide cleaning liquid to the cleaning area. Also provided within the housing 1 is a dispenser 4, the dispenser 4 having a liquid inlet 4a, a liquid outlet 4b and being hollow in the interior to form a diversion channel 44, the liquid inlet 4a being located upstream of the diversion channel 44 along the flow path of the fluid, the liquid outlet 4b being disposed adjacent the mounting aperture 17 and upstream of the flow passage 100. The arrangement form of the liquid outlet 4b is free from other liquid supply components, the negative pressure suction force of the negative pressure source can directly extract the cleaning liquid, and the cleaning liquid can be synchronously supplied only by starting the negative pressure under the condition that the cleaning liquid is sufficiently stored in the shell, so that the cleaning liquid supply device is quite convenient. Of course, for some cleaning solutions that need to be stored in a sealed manner, the solution may also be supplied by pumping, for example, the pump body 12 and the infusion tube 13 may be disposed at the rear side of the housing 1, and the infusion tube 13 is connected between the pump body 12 and the liquid inlet 4 a. Two liquid supply schemes can be selected and reserved in actual production, and liquid supply modes are switched by changing the connection positions of pipelines in use.

The liquid outlet 4b may have different liquid outlet directions as long as the cleaning liquid can be supplied, but in the present embodiment, the liquid outlet 4b described above is arranged with its opening facing downward. Because the flow channel 100 in the present application causes fluid not to flow vertically, this will cause the air flow passing through quickly to be sucked away by the negative pressure without the liquid fully contacting the surface 102 to be cleaned, so the liquid outlet is arranged downward, so that the liquid has a longer moving path and residence time in the flow channel 100 as much as possible, and the cleaning effect is ensured. In order to match the flow of the cleaning liquid, a diversion hole 11 which extends in the same direction as the mounting hole 17 and is communicated with the liquid outlet 4b is formed in the shell 1, and the diversion hole 11 is arranged in an area surrounded by the annular wall 18.

The aforementioned liquid dispenser 4 may be in different specific forms, and the liquid dispenser 4 in this embodiment includes a strip-shaped body 41 and flow guiding seats 42 formed at the ends of the body, the flow guiding seats 42 are disposed at the first sides at two ends of the body 41, and at least one liquid outlet 4b is correspondingly disposed on each flow guiding seat 42. The above-mentioned diversion bases 42 have an arc structure with two ends bent toward the first side, and each diversion base 42 has a liquid outlet end 43 extending downward at the bottom of the two ends, and the liquid outlet 4b is opened on the liquid outlet end 43. In order to achieve the distribution of the liquid, the diversion channel 44 includes a first flow channel 441 formed in the body 41 and a second flow channel 442 formed in each diversion seat 42, and each second flow channel 442 is at least partially overlapped with the first flow channel 441 in a same direction. In addition, a slow flow passage 443 is provided at the junction between each second flow passage 442 and the first flow passage 441, and the extending direction of the slow flow passage 443 intersects with the extending directions of the first flow passage 441 and the second flow passage 442. By designing the slow flow passage 443 in this way, it is possible to ensure that the liquid fed from the liquid inlet 4a is not inadvertently reduced, and the pressure distribution is performed by the slow flow passage 443, thereby ensuring that the liquid discharged from the liquid outlet 4b is uniform.

In the present embodiment, the liquid inlet 4a is formed on the first side of the body 41 and is located in the middle of the body 41, and the first flow channel 441 is provided with a flow guiding portion 45 on an inner side wall opposite to the liquid inlet 4a for diverting the liquid to two sides of the liquid inlet 4 a. The flow guiding portion 45 in the present embodiment is a protrusion extending from the inner side wall of the first flow channel 441 toward the liquid inlet 4a, and the inner side wall corresponding to the first flow channel 441 smoothly transitions from the protrusion to both sides.

In this embodiment, the brush 5 is designed in a special manner, that is, the brush 5 includes a base 51 and a flexible brush plate 52, where the base 51 is in a disc shape, the brush plate 52 is in a strip shape and at least one of the brush plates is installed at the bottom of the base 51 and is radially arranged with respect to the center of the base 51. In order to mount and dismount the brush plate 52, a positioning groove 53 is provided at the bottom of the base 51 at a position corresponding to the brush plate 52, and the brush plate 52 is detachably mounted in the positioning groove 53. Specifically, a mounting seat 54 extends downward from the bottom of the base 51, a positioning groove 53 is formed in the mounting seat 54, a socket 55 is formed in a side wall of the positioning groove 53 adjacent to the outer edge of the base 51, and the brush plate 52 is inserted into the positioning groove 53 from the socket 55.

In order to ensure the vertical limit of the brush plate 52, the brush member 52 adopts a double safety measure, in which the caliber of the socket 55 gradually shrinks from top to bottom, so that the brush plate 52 is "clamped" by the socket 55 even if the brush plate 52 has a downward movement tendency; secondly, a blocking edge 531 is formed by extending inwards on the side wall of the positioning groove 53, and blocking edges 521 extending laterally are arranged on two sides of the corresponding brush plate 52, and in the state that the brush plate 52 is inserted into the positioning groove 53, the blocking edge 531 is located above the blocking edges 521, so that the brush plate 52 is vertically limited in the positioning groove 53. Of course, in order to avoid the risk of falling off the brush plate 52, the brush plate 52 may be integrally formed on the seat 51 during injection molding, and in actual production, if the cost is not considered, the integrally formed design can greatly reduce the rotation defect of the brush member 5 itself, for example, during assembly, the detachable design can shake the components, generate noise, and may also accumulate dust at the holes. And thus a one-piece design is preferred.

The brush 5 can perform a liquid-homogenizing function which is important as a "liquid-distributor" in addition to a brushing function on the surface 102 to be cleaned. In the case of the flow channel 100, the liquid can be supplied only through the liquid outlet 4b and the diversion holes 11, and the flow channel 100 cannot be directly fully covered, which may result in uneven distribution of the cleaning liquid and different cleaning effects at different positions, in order to cope with this situation, at least two brush plates 52 are arranged at intervals, and the rotation path of at least one brush plate 52 passes through the liquid outlet 4b. In this arrangement of the brush plate 52 and the liquid outlet 4b, if the viewing angle is collected on a single brush plate 52, each turn of the brush plate passes through the position below the deflector hole 11, so that the cleaning liquid is dispersed each time the brush plate passes through the liquid outlet 4b, and a large part of the cleaning liquid remained on the brush plate 52 is thrown to uniformly spread over the entire flow channel 100 along with the rotation of the brush member 5. And since the liquid outlet 4b is arranged with the opening facing downwards in the upper position, the brush plate 52 in a strip shape has a larger striking area and better scattering effect.

The brush 5 in this embodiment may be driven by negative pressure to follow the airflow, but such sweeping force is insufficient, so it is preferable to use a power source for driving, and the front side of the housing 1 is further provided with a driving mechanism 3, where a power output end of the driving mechanism 3 is in driving connection with the brush 5. Specifically, at least two flow passages 100 are arranged at intervals on the front side of the housing 1, a brush 5 is correspondingly arranged in each flow passage 100, the driving mechanism 3 comprises a driver 32 and a gear box 31, the output end of the gear box 31 is provided with at least two driving shafts 14, each driving shaft 14 extends vertically and can rotate around the axis of the driving shaft 14, and the brush 5 is arranged on the driving shaft 14 and can synchronously rotate along with the driving shaft 14. The housing 1 has a notch 101 on the front side, and the drive mechanism 3 is detachably attached to the notch 101, and an attachment hole 17 is formed vertically penetrating the housing 1 at a position corresponding to the notch 101.

In addition, the flow channels 100 in the present embodiment are arranged in groups, each two flow channels 100 are arranged in a group and have one exhaust channel 1e, and two flow channels 100 in the same group are communicated with the corresponding exhaust channels 1e through respective air outlets 1 d. Specifically, the flow passages 100 are four and are formed in two groups, and the rotation directions of the brushes 5 in the two groups of flow passages 100 are opposite, so that the two exhaust passages 1e meet at the middle of the rear side of the housing 1. By the aid of the design of the flow channels 100 and the exhaust channels 1e, rotation of the brush 5 is related to trend of air flow, the middle positions of the two groups of flow channels 100 form a collecting position of the air flow due to the fact that the rotation directions of the two groups of flow channels 100 are opposite, and due to the fact that annular walls exist, the air flow collides in the flow channels 100 in a spiral mode, mutual gains can be generated, accordingly flow velocity of fluid in each flow channel 100 is greatly improved, good cleaning effect is achieved, and in actual production, communication degree among the flow channels 100 can be regulated and controlled through arrangement of the height of the annular walls according to the final cleaning effect, and therefore ideal cleaning effect is achieved. Of course, the exhaust channels 1e may also adopt different structural designs, and in particular, see fig. 6, 17 and 18, where the above description refers to the case of fig. 18, that is, the two exhaust channels 1e meet at the middle of the rear side of the housing 1, or the structure shown in fig. 6, that is, the two flow channels 100 in the middle combine and exhaust air, and exhaust air through one larger exhaust channel 1e, and the flow channels 100 on two sides respectively exhaust air through the corresponding exhaust channels 1 e; it is also possible that, as shown in fig. 17, each flow passage 100 corresponds to one exhaust passage 1e.

The term "fluid communication" as used herein refers to a spatial positional relationship between two components or parts (hereinafter collectively referred to as a first part and a second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow along a flow path from the first part to the second part or/and be transported to the second part, or the first part and the second part may be directly communicated with each other, or the first part and the second part may be indirectly communicated with each other through at least one third party, and the third party may be a fluid channel such as a pipe, a channel, a conduit, a flow guiding member, a hole, a groove, or the like, or a chamber allowing the fluid to flow through, or a combination thereof.

Furthermore, directional terms, such as "front", "rear", "upper", "lower", "left", "right", "side", "top", "bottom", etc., are used in the description and claims of the present invention to describe various example structural parts and elements of the present invention, but are used herein for convenience of description only and are determined based on the example orientations shown in the drawings. Because the disclosed embodiments of the invention may be arranged in a variety of orientations, the directional terminology is used for purposes of illustration and is in no way limiting, such as "upper" and "lower" are not necessarily limited to being in a direction opposite or coincident with the direction of gravity.
