Description

Technical Field

[0001] This invention relates to steam cleaning equipment technology, and is particularly applicable to steam floor scrubbers and steam cleaning machines with roller brushes. Background Technology

[0002] Existing steam cleaning equipment with roller brushes mostly uses a fixed-flow design for steam distribution, resulting in steam being continuously sprayed towards both the cleaning surface and the roller brush simultaneously. This has the following drawbacks:

[0003] Cleaning modes cannot be switched: Daily mopping only requires spraying high-temperature steam onto the floor to dissolve stains. Continuously spraying steam onto the roller brush will cause steam waste, rapid heating of the whole machine, and high energy consumption. When cleaning the roller brush alone, it is impossible to concentrate steam to sterilize and remove scale from the roller brush at high temperature, resulting in low cleaning efficiency.

[0004] Uneven steam distribution: When two steam streams are released simultaneously, the steam pressure is distributed, resulting in insufficient steam impact on the ground, making it difficult to remove stubborn stains; insufficient steam volume on the roller brush side makes it impossible to quickly kill bacteria growing inside the roller brush or dissolve hair and dirt.

[0005] No independent on / off control structure: Relying on pipeline diversion, it is impossible to shut off any one of the steam lines individually, and the needs of two operating conditions cannot be met at the same time, limiting the applicable scenarios of the equipment.

[0006] Therefore, there is an urgent need for a steam conveying structure that can switch between two steam on / off paths, achieve centralized steam output, and adapt to different cleaning conditions. Summary of the Invention

[0007] To address the shortcomings of existing technologies, such as the inability to independently control the flow of steam, dispersed steam pressure, and poor adaptability to operating conditions, this invention provides a steam delivery structure and cleaning equipment. By switching between two steam paths through a swingable steam distribution mechanism, it enables independent switching between two modes: ground steam cleaning and roller brush steam self-cleaning. This concentrates steam pressure to improve cleaning efficiency and reduce steam loss.

[0008] To achieve the above and other related objectives, the technical solution provided by the present invention is: a steam conveying structure, including a roller brush cover, a steam distribution chamber formed in the roller brush cover, a steam inlet, a first steam nozzle, and a second steam nozzle connected to the steam distribution chamber on the roller brush cover, the steam inlet being connected to an external steam generating module, the first steam nozzle being disposed facing the cleaning surface, and the second steam nozzle being disposed facing the roller brush; a steam distribution mechanism is provided in the steam distribution chamber, the steam distribution mechanism being used to switch the first steam nozzle and the second steam nozzle on and off.

[0009] The preferred technical solution is: multiple sets of the first steam nozzles are arranged at equal intervals along a first direction, and the first direction is parallel to the axis of the roller brush.

[0010] The preferred technical solution is: multiple sets of the second steam nozzles are arranged at equal intervals along the second direction, and the second direction is parallel to the axis of the roller brush.

[0011] A preferred technical solution is as follows: a first cavity is formed in the roller brush cover, the first cavity is connected to the steam distribution cavity, and the first steam nozzle is connected to the first cavity.

[0012] A preferred technical solution is that a second cavity is formed in the roller brush cover, the second cavity is connected to the steam distribution cavity, and the second steam nozzle is connected to the second cavity.

[0013] The preferred technical solution is as follows: the steam distribution chamber has at least a first sidewall and a second sidewall arranged perpendicularly to each other, the first sidewall is provided with a first through hole communicating with the first cavity, and the second sidewall is provided with a second through hole communicating with the second cavity.

[0014] The preferred technical solution is that the steam distribution mechanism consists of a motor and a plug, and the motor is used to drive the plug to swing 90 degrees to block the first through hole on the first side wall or the second through hole on the second side wall.

[0015] The preferred technical solution is as follows: the roller brush cover is provided with a motor assembly cavity, the motor is fixed in the motor assembly cavity and the output shaft extends into the steam distribution cavity.

[0016] The preferred technical solution is as follows: the block is composed of a bracket and a rubber sleeve, the bracket is fixed on the output shaft of the motor, and the rubber sleeve is configured as a square cylindrical structure and sleeved on the free end of the bracket.

[0017] A cleaning device includes the steam delivery structure described above.

[0018] Due to the application of the above technical solution, the beneficial effects of this invention are as follows:

[0019] It achieves independent switching between two modes to adapt to different cleaning conditions; the motor drives the blocking block to swing 90° to seal the corresponding through hole, allowing independent access to the first steam nozzle on the ground side or the second steam nozzle on the roller brush side. When mopping, the steam on the roller brush side is turned off, and all steam is delivered to the ground; when the roller brush is self-cleaning and sterilizing, the steam on the ground is turned off, and the steam is concentrated to wash the roller brush, solving the pain point of traditional equipment where two steam sources are output simultaneously and the operating conditions cannot be switched.

[0020] Concentrated steam pressure significantly enhances cleaning power; steam is output in a single path without diversion or pressure relief, resulting in higher concentration of steam impact and temperature. During floor cleaning, high-temperature, high-pressure steam quickly dissolves stubborn oil and sticky stains; during roller brush self-cleaning, sufficient high-temperature steam penetrates the roller brush fibers, effectively sterilizing and dissolving tangled hair, solving the problems of insufficient steam pressure and poor cleaning effect caused by traditional diversion methods.

[0021] Reduces ineffective steam loss and lowers overall energy consumption; eliminates the need to continuously spray steam onto the side that is not in use, avoiding steam waste, shortening the continuous steam production load of the steam generation module, resulting in lower overall power consumption and longer operating time per water refill, thus solving the defects of ineffective steam consumption and high energy consumption in traditional equipment.

[0022] It features stable sealing, a compact and durable structure, and a block that uses a square rubber sleeve to seal the through hole, ensuring good sealing performance and preventing steam leakage. The motor is integrated into the motor assembly cavity inside the roller brush cover, resulting in high overall integration. It eliminates the need for an external valve body, occupies little space, and is compatible with the internal structure of small floor scrubbers, with fewer parts and a low failure rate.

[0023] Uniform, full-area spray ensures thorough cleaning without any blind spots; both nozzles are equidistantly arranged along the roller brush axis, evenly distributing steam within the corresponding chambers. Steam can cover the entire area of ​​the ground and roller brush, eliminating any areas without steam and resulting in better cleaning uniformity. Attached Figure Description

[0030] Example:

[0031] like Figures 1 to 3 As shown, according to an overall technical concept of the present invention, a steam conveying structure is provided, the main body of which is a roller brush cover 1, and the roller brush cover 1 has an integrally formed steam distribution cavity 100, a motor assembly cavity (not shown), a first cavity 200, and a second cavity 300 inside.

[0032] A steam inlet 11 is provided on the outside of the roller brush cover 1. The steam inlet 11 is connected to the steam generation module of the whole machine. High-temperature steam is sent into the steam distribution chamber 100 through the steam inlet 11.

[0033] Multiple sets of first steam nozzles 2 are equidistantly arranged at the bottom of the roller brush cover 1 along the roller brush axis. The first steam nozzles 2 are connected to the first cavity 200, and the steam is sprayed out and directly acts on the ground cleaning surface. Multiple sets of second steam nozzles 3 are arranged on the inner side of the roller brush cover 1 facing the roller brush side. The second steam nozzles 3 are connected to the second cavity 300, and the steam is directly sprayed onto the roller brush bristles.

[0034] The steam distribution chamber 100 has a first sidewall and a second sidewall that are perpendicular to each other. The first sidewall has a first through hole 110 that connects to the first chamber 200, and the second sidewall has a second through hole 120 that connects to the second chamber 300.

[0035] A drive motor (not shown) is fixedly installed inside the motor assembly cavity. The motor output shaft extends into the steam distribution cavity and is connected to the plug 4. The plug 4 is composed of a plastic bracket 41 and a square rubber sleeve 42. The rubber sleeve 42 elastically fits the end face of the through hole to achieve a seal.

[0036] Working process and principle:

[0037] Floor mopping cleaning mode: The whole machine control motor drives the block 4 to swing 90°, the rubber sleeve 42 seals the second through hole 120 on the second side wall, and the passage of the second cavity 300 and the second steam nozzle 3 is closed; the steam in the steam distribution chamber 100 can only flow into the first cavity 200 through the first through hole 110, and is evenly sprayed onto the ground by all the first steam nozzles 2, and the high temperature steam is concentrated to dissolve the stains on the ground. At this time, no steam flows to the roller brush to avoid steam waste.

[0038] Self-cleaning and sterilization mode of the roller brush: The motor drives the block 4 to swing 90° to reset in reverse, and the rubber sleeve 42 seals the first through hole 110 on the first side wall, closing the passage of the first cavity 200 and the first steam nozzle 2; all the steam enters the second cavity 300 through the second through hole 120 and is sprayed from the second steam nozzle 3 in all directions. The high-temperature steam penetrates the bristles, kills bacteria inside the roller brush, dissolves the tangled hair and dirt, and completes the self-cleaning of the roller brush.

[0039] The two modes can be freely switched through the whole machine's electronic control program. Only one path is open throughout the entire process, and there is no steam diversion or pressure loss, resulting in stable output pressure.

[0040] This embodiment also discloses a cleaning device, which can be a steam floor scrubber, a steam mop, or a roller brush steam cleaner. The main body of the device is equipped with the aforementioned steam delivery structure to achieve switchable dual-path steam output.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
