Description

Technical Field

[0001] This utility model relates to cleaning equipment, and more particularly to a scrubbing head assembly with a built-in spray washing structure. Background Technology

[0002] Patent document CN220311108U discloses a cleaning nozzle, which includes a nozzle body, a spray nozzle, and a splash guard. The spray nozzle is located at the bottom of the nozzle body, and the splash guard has a semi-enclosed space for housing the spray nozzle. A limiting fastener extends upward from the top of the splash guard, and the height of the limiting fastener is greater than the thickness of the nozzle body. The splash guard covers the spray nozzle in the semi-enclosed space, and the limiting fastener is pressed upward against the top of the nozzle body so that the splash guard can be detachably installed on the nozzle body. This cleaning nozzle, by making the splash guard independent and detachably installed on the nozzle body, allows users to choose the suction function of the nozzle body alone for dry cleaning, or to choose the nozzle body and spray nozzle together for wet cleaning, depending on the actual usage scenario. In one type of cleaning machine, the spray nozzles are connected to a steam generator. Steam is sprayed from the nozzles to clean the items, creating wastewater which is then sucked up by the nozzle body. However, the distance between the spray nozzles and the openings of the nozzle body is relatively large, causing significant heat loss during steam transport. As a result, the steam reaches the surface of the items being cleaned at a drastically reduced temperature, leading to poor cleaning performance. Therefore, it is necessary to optimize the structure of this cleaning nozzle to overcome these shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide a scrubbing head assembly with a built-in spray washing structure to improve the cleaning effect.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A squeegee assembly with a built-in spray washing structure includes:

[0006] The main body of the scraper head has a suction port at one end and an adapter port at the other end. The adapter port can be connected to the suction mechanism through a pipeline, so that the dirt can enter the interior of the scraper head from the suction port and be transported to the suction mechanism from the adapter port.

[0007] Also includes:

[0008] The spraying horizontal pipe is installed inside the excavator head body near the suction port and is connected to the steam or water supply mechanism through a pipeline. Water and steam nozzles are opened on its side. Steam, hot water or cold water is supplied to the spraying horizontal pipe by the steam or water supply mechanism, so that it is sprayed out from the water and steam nozzles and output from the suction port of the excavator head body. A gap is left between the outer wall of the spraying horizontal pipe and the inner wall of the excavator head body to allow the suction airflow to pass through.

[0009] In one embodiment of this utility model, the water vapor nozzles extend radially along the spraying horizontal pipe and are arranged sequentially along the axial direction in the spraying horizontal pipe, with their outer ends pointing towards the rear edge of the suction port of the squeegee body.

[0010] In one embodiment of this utility model, the two ends of the spraying horizontal pipe are respectively inserted into the side wall of the squeegee body. After extending outward from the squeegee body, it is sealed by a detachable sealing end. The sealing end can be removed to clean the inside of the spraying horizontal pipe and avoid blockage.

[0011] In one embodiment of this utility model, a transfer steam pipe is connected to the middle of the spray horizontal pipe. The transfer steam pipe passes through the side wall of the main body of the extruder and extends from the suction port to the transfer port.

[0012] In one embodiment of this utility model, a switching valve is connected to the end of the transfer steam pipe. The switching valve is connected to the steam supply or water supply mechanism through a pipeline, and the switching valve switches the on / off state of the steam supply or water supply mechanism and the spray washing horizontal pipe.

[0013] In one embodiment of this utility model, a suction grip tube is inserted into the adapter port of the excavator head body. The end of the suction grip tube is connected to the suction mechanism through an adapter hose. The excavator head body can be moved by holding the suction grip tube. A switching valve is installed on the side of the suction grip tube.

[0014] In one embodiment of this utility model, the main body of the scraper head has a suction expansion section, which corresponds to the position of the spray washing horizontal pipe and expands outward to ensure that the distance between the outer wall of the spray washing horizontal pipe and the inner wall of the scraper head meets the requirements for airflow.

[0015] In one embodiment of this utility model, the outer wall of the tap head body is provided with a protective cover. The protective cover extends along the extension direction of the transfer pipe and covers the outside of the transfer pipe to protect it.

[0016] The advantages of this utility model are:

[0017] This cleaning head assembly features a built-in horizontal spray pipe with steam and water jets. The spray pipe is close to the suction port, and the spray pressure is higher than the suction pressure, ensuring effective steam or water output at the set temperature while minimizing leakage and wastewater splashing. It quickly softens stubborn stains, grease, and adhesives as the cleaning head moves, making them easier to remove while reducing dust and secondary pollution. The spray pipe has detachable, sealed ends for easy cleaning of internal blockages. A steam transfer pipe and switching valve control the steam flow, making operation convenient. The suction expansion section ensures sufficient space for airflow, and a protective cover protects the transfer pipe, enhancing durability. Its compact structure and high functional integration significantly improve cleaning efficiency and user experience. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0022] like Figures 1-3 As shown, the scraper head assembly with a built-in spray washing structure proposed in this utility model includes a scraper head body 100 and a spray washing horizontal pipe 200. One end of the scraper head body has a suction port 110, and the other end has a conversion port 120. The conversion port can be connected to the suction mechanism through a pipeline, so that dirt can enter the interior of the scraper head body from the suction port and be transported to the suction mechanism from the conversion port. The spray washing horizontal pipe is installed inside the scraper head body near the suction port and is connected to the steam or water supply mechanism through a pipeline. A steam spray hole 210 is opened on its side. The steam or water supply mechanism supplies steam, hot water or cold water to the spray washing horizontal pipe, so that it is sprayed out from the steam spray hole and output from the suction port of the scraper head body. A gap is left between the outer wall of the spray washing horizontal pipe and the inner wall of the scraper head body to allow the suction airflow to pass through.

[0023] In this embodiment, the steam nozzles extend radially along the horizontal spray tube and are arranged sequentially along the axial direction within the tube, with their outer ends pointing towards the rear edge of the suction port on the main body of the broom. During use, the main body of the broom moves rearward, and the steam ejected from the steam nozzles first contacts the surface of the item, quickly softening stubborn stains, grease, and adhesives adhering to the surface. It can penetrate the stains, and the high temperature promotes grease emulsification, making it easier to remove. After the steam wets the surface, dust is less likely to fly away, avoiding secondary pollution. Because the distance between the horizontal spray tube and the suction port is relatively short, the spray pressure from the steam nozzles is greater than the suction pressure of the suction mechanism, ensuring that steam leakage and wastewater splashing are reduced while the steam is ejected outward from the suction port.

[0024] In this embodiment, the two ends of the spraying horizontal pipe are respectively inserted into the side wall of the squeegee body. After extending outward from the squeegee body, it is sealed by a detachable sealing end 220. The sealing end can be removed to clean the inside of the spraying horizontal pipe and avoid blockage.

[0025] In this embodiment, a transfer steam pipe 230 is connected to the middle of the spray pipe. This transfer steam pipe passes through the side wall of the main body of the scraper head and extends from the suction port towards the transfer port. In this embodiment, to facilitate the arrangement of the transfer steam pipe, a U-shaped notch is provided at the edge of the suction port of the scraper head body, and the transfer steam pipe extends from the U-shaped notch to the outside of the scraper head body. At the same time, it should be noted that the transfer steam pipe should be inclined inward in the U-shaped notch to avoid interference and collision between the scraper head body and the surface of the object during movement.

[0026] In this embodiment, a switching valve 240 is connected to the end of the transfer steam pipe. This switching valve is connected to the steam or water supply mechanism through a pipeline. The switching valve switches the on / off state of the steam or water supply mechanism and the spray horizontal pipe, and the steam or water flows along... Figure 1 The flow is in the direction of the middle arrow.

[0027] In this embodiment, a suction grip tube 250 is inserted into the adapter port of the excavator body. The end of the suction grip tube is connected to the suction mechanism through an adapter hose. The excavator body can be moved by holding the suction grip tube. A switching valve is installed on the side of the suction grip tube.

[0028] In this embodiment, the main body of the scraper head has a suction expansion section (not shown in the figure). This suction expansion section corresponds to the position of the spray horizontal pipe and expands outward to ensure that the distance between the outer wall of the spray horizontal pipe and the inner wall of the scraper head meets the requirements for airflow.

[0029] In this embodiment, the outer wall of the excavator body is provided with a protective cover (not shown in the figure). The protective cover extends along the extension direction of the transfer pipe and covers the outside of the transfer pipe to protect it.
