Description

Synchronous transmission type sweeping and mopping integrated cleaner

Technical Field

The invention relates to the field of cleaning equipment, in particular to a synchronous transmission type sweeping and mopping integrated cleaner.

Background

In daily cleaning operations, the sweeping and mopping/mopping operations are performed separately and independently of each other. The common cleaners are divided into two types, one type is a dry cleaner, namely, the cleaner can only perform a sweeping function in a dry environment or a relatively dry environment, and generally can only clean dirt with large volume (the particle size or the length is more than 1 cm), but cannot clean small dirt (the particle size is less than 2 mm); the other is a wet cleaner, which can only perform a floor wiping or mopping function in a wet environment, and can only clean small and medium-sized (particle size below 1 cm) or fluid/semi-fluid/deformable dirt, but cannot perform a large-volume dirt cleaning operation, so that a set of other types of cleaners must be additionally provided in a household regardless of whether a dry cleaner or a wet cleaner is provided, which increases the household purchase cost and the space occupation, and causes poor experience in frequent switching between the two cleaners.

In the operation process of the traditional cleaner which has both floor sweeping and floor mopping functions, the following technical problems still exist:

if only one dual-purpose cleaning head is adopted to clean the ground, the dual-purpose cleaning head not only can clean large-volume dirt but also can clean small-particle dirt, so that the requirement on the cleaning head is extremely strict, and the two difficult situations that large heads are considered but small heads are not considered are often caused; if multiple different purpose cleaning heads are used to clean the floor, the cleaner is too awkward and inconvenient for the operator to use due to the excessive introduction of cleaning heads and multiple actuators.

In view of the above, how to design a reasonable cleaning head assembly to balance the cleaning requirement of large-volume dirt and the cleaning requirement of small-particle dirt is an urgent problem to be solved for the sweeping and mopping integrated cleaner.

a driver provided in the base 11; and

a transmission member mechanically coupling the front and

rear cleaning heads

12, 13 to the driver for synchronously transferring mechanical energy from the driver to the front and

rear cleaning heads

12, 13. The cleaning chamber 111 and the dry garbage collection chamber 112 are communicated with each other through an ash throwing channel 1224; the combing member 123 is arranged on the upstream side in the dust conveying direction of the dust throwing passage 1224; the front cleaning head 12 includes:

a cylindrical front roller 125 rotatably connected to the cleaning chamber 111 in a lateral direction; and

at least three rolling brush blades 121 radially arranged on the circumference of the front roller, the rolling brush blades 121 surrounding the axis X of the front roller₁Extending in a spiral shape;

wherein each of the rolling brush blades 121 includes a plurality of bristles extending radially outward; the combing member 123 is located on a rotation path of the drum brush blade 121 such that the bristles of the drum brush blade 121 are combed by the combing member 123 during periodic rotation with the front drum 125. So that when the bristles pass through the combing member 123, dirt such as hair, lint, filaments, etc. wound on the bristles can be intercepted by the combing member, and can be cut into finer dirt pieces by the bristles and carried forward again by the following bristles as the rolling brush blades continuously rotate, and then the dirt is thrown into the dry garbage collection chamber 112 through the dust throwing channel 1224 under the action of its own centrifugal force and inertia force, so as to be collected. Hereinafter and throughout the specification, the terms "front/front side" and "rear/rear side" should be understood as referring to the forward direction of the synchronous drive type integral sweeping cleaner, which is specifically indicated by the arrow H in fig. 1 and 5, wherein the direction indicated by the arrow H is "front/front side" and the direction opposite to the arrow H is "rear/rear side".

As a further improvement, the transmission member 16 is at least one of a belt, a gear set and a chain. Referring to fig. 2, in the embodiment shown in fig. 2, the transmission member 16 is a rack and pinion structure, specifically, the rack and pinion structure includes an annular transmission rack 161 connected end to end, and a front transmission gear 162 and a rear transmission gear 163 disposed at the same side, the front transmission gear 162 is fixedly connected to one end of the front cleaning head 12, the rear transmission gear 163 is fixedly connected to one end of the rear cleaning head 13, the annular transmission rack 161 is sleeved on the front transmission gear 162 and the rear transmission gear 163 and respectively engaged with the outer peripheries of the front transmission gear 162 and the rear transmission gear 163, and the driver is mechanically coupled to the annular transmission rack 161, so that the driver synchronously transmits mechanical energy to the front cleaning head 12 and the rear cleaning head 13 through the annular transmission rack 161.

In the embodiment shown in fig. 5 and 8, the comb member 123 comprises:

a guide part 1231, the guide part 1231 being located on an upstream side of the rotation direction of the roll brush blade 121; and

a comb part 1233 integrally molded on the guide part 1231 at a downstream side in the rotation direction of the roll brush blade 121;

wherein the comb part 1233 includes a plurality of comb teeth 1234 spaced along the axial direction of the front drum 125; each comb teeth 1234 extends from the guide portion 1231 toward the front roller 125 such that each comb tooth 1234 at least partially intrudes into a rotation path of the brush blade 121. So that the hairs, flocks, filaments, etc. entangled/entrained on the bristles are intercepted by the comb teeth 1234 of the comb member while the bristles pass through the comb member 123. In a preferred embodiment, each comb tooth 1234 has an intrusion depth that is the same as its extended length.

Referring to fig. 9 and 10, as a further modification, a side surface of the guide portion 1231 facing the brush roller 121 is a guide surface 1231a having an arc-shaped cross section, and a radially outer end surface of the brush roller 121 is fitted to the guide surface 1231a during rotation. Thereby forming a guard space between the guide part 1231 and the front drum 125, the guide part 1231 can prevent dirt intercepted on the comb teeth 1234 from being scattered around in the process of being cut into finer dirt pieces by the brush bristles, and the brush blades can form a micro air flow in the guard space in correspondence with the rotating direction thereof along with the periodic rotation of the brush blades, thereby promoting the cut dirt pieces to more rapidly pass through the front barrier 122 under the influence of the micro air flow.

In the embodiment shown in fig. 5 and 6, a cleaning opening 1111 is opened at a bottom wall of the cleaning chamber 111 such that at least a portion of the brush roller blade 121 is exposed from the cleaning opening 1111 when the front cleaning head 12 is installed in the cleaning chamber 111. So that the roll brush blade can sweep the surface to be cleaned through the sweeping opening 1111.

With reference to fig. 5, 6 and 7, as a further modification, a front baffle 122 is disposed around the outer periphery of the front cleaning head 12; the front barrier 122 ends at the front side of the front drum 125 after passing at least 1/4 and at most 3/5 of circumference from the inlet of the ash-dumping channel 1224 in the direction of rotation of the front drum 125 to form the sweeping opening 1111 between the lower edge 1223 of the front barrier 122 and the bottom wall of the sweeping chamber 111.

In the embodiment shown in fig. 6, when the front cleaning head 12 is installed in the cleaning chamber 111, a cleaning gap is formed between the inner side of the front barrier 122 and the front drum 125, and a cleaning inlet 126 is formed between the rear side 1112 of the cleaning opening 1111 and the front drum 125; the comb member 123 is arranged in the sweeping gap.

In the embodiment shown in FIG. 5, the lower edge 1223 of the front baffle 122 defines the front side of the scavenge opening 1111; a scraper 124 is provided in the cleaning inlet 126, one end of the scraper 124 is connected to the rear side 1112 of the cleaning opening 1111, and the other end of the scraper 124 faces the surface S to be cleaned.

In the technical solution provided by the embodiment of the present invention, the scraper 124 can collect the dirt on the surface S to be cleaned, such as sewage, dust, lint, hair, and filiform debris, so that the front cleaning head 12 can quickly clean the surface S to be cleaned when working, and the cleanliness of the surface S to be cleaned after cleaning is higher.

In the embodiment shown in fig. 6 and 12, the front roller 125 rotates clockwise under the driving of the driver, three rolling brush blades 121 radially arranged on the circumference of the front roller rotate clockwise along with the front roller 125, the three rolling brush blades 121 alternately contact with the surface S to be cleaned during the rotation, so that the dirt on the surface S to be cleaned is swept back into the sweeping inlet 126, and the dirt is thrown into the dust throwing channel 1224 under the action of the centrifugal force and the inertia force of the dirt, and is finally collected by the dry waste collection chamber 112. Hereinafter and throughout the specification, the term "toward the surface to be cleaned" should be understood to mean that the other end of the scraper 124 extends toward the surface S to be cleaned, and in one embodiment of the present invention, the other end of the scraper 124 extends to be close to the surface S to be cleaned, but not limited thereto, and in other embodiments, the other end of the scraper 124 may be suspended above the surface S to be cleaned.

In order to increase the effective area of the scraper 124, referring to fig. 12, the scraper 124 is along the axial direction X of the front roller 125₁And (4) extending.

Referring to fig. 11 to 13, in order to prevent water stains or solid-liquid mixed dirt in the wet environment from being thrown into the dry garbage collecting chamber 112, a plurality of water guiding grooves 1242 are formed through the scraper 124, and two adjacent water guiding grooves 1242 are spaced from each other and arranged along the axial direction X of the front roller 125₁Are arranged in an extended manner. So that moisture in the cleaned dirt can be leached out and retained on the surface S to be cleaned through the water guiding through-groove 1242 after the cleaned dirt enters the cleaning inlet 126 and before the dirt enters the dust-throwing channel 1224.

Referring to fig. 12 and 13, in order to improve the efficiency of draining water from the dirt, the scraper 124 has a dirt collecting guide surface 1241 on a side opposite to the front roller 125; the cross section of the object guide surface 1241 is arc-shaped, and the radial outer end surface of the rolling brush blade 121 is matched with the object guide surface 1241 in the rotation process. The drained water is guided by the guide surface 1241 and then quickly falls into the water chute 1242, while the relatively dry dirt is quickly thrown into the ash-throwing channel 1224 under the guidance of the guide surface 1241.

As a further improvement, a water guide surface 1243 is disposed on the object guide surface 1241. Water or solid-liquid mixed dirt can be introduced into the water guide grooves 1242 more quickly through the water guide surfaces 1243.

Referring to fig. 2, 4 and 14, a wet garbage collection chamber 113 and a wiping chamber 114 are further provided in the base 11, and the wet garbage collection chamber 113 and the wiping chamber 114 are sequentially arranged behind the dry garbage collection chamber 112 along a front-to-back direction; wherein a rear cleaning head 13 is laterally rotatably connected in the wiping chamber 114. In other embodiments, the top of the base 11 is provided with a connector 15, and the synchronous transmission type sweeping and mopping integrated cleaner can be connected with other accessories through the connector 15, such as a handle of the cleaner, a mobile power supply of the cleaner and the like; meanwhile, the bottom of the base 11 is rotatably connected with at least three rollers 1151 which are arranged non-collinearly.

In practical use, the cleaning mode of the synchronous transmission type integral cleaning device can be a sweeping and mopping type integral cleaning device, i.e. the front cleaning head 12 performs a sweeping function, and the rear cleaning head 13 performs a mopping function, in order to further improve the cleaning efficiency, a spraying head 1222a for spraying cleaning water or cleaning agent is generally arranged at the front side of the front baffle 122, the spraying head 1222a sprays the cleaning water or cleaning agent towards the path to be cleaned before or during cleaning, and the spraying of the cleaning water or cleaning agent on the path to be cleaned can improve the cleaning efficiency and the sweeping ratio. In the embodiment shown in fig. 6, a liquid supply pipe 1222b for supplying detergent or cleaning water to the spray head 1222a is extended inside the simultaneous transmission type sweeping and mopping integrated cleaner. In other embodiments, at least one lighting lamp 1221 is disposed at the front side of the front baffle 122, and the lighting lamp can be turned on in a dark environment to illuminate an area to be cleaned, so as to provide a visual field for a user and improve the use experience of cleaning operation.
