Description

Technical Field

[0001] This utility model relates to the technical field of cleaning pipelines, and in particular to an internal cleaning pipeline structure for a cleaning machine. Background Technology

[0002] As a type of cleaning appliance, cleaning machines are widely used in homes, hotels, and other places. The main functions of a cleaning machine are cleaning, scrubbing, and recycling. During cleaning, water from the clean water tank is delivered through pipes to the nozzles on the floor brush for cleaning.

[0003] In existing technology, the handle connector of a cleaning machine is often equipped with a flexible connector, which connects to the cleaning body to improve operational flexibility. However, after repeated use, the flexible connector or other fittings of the handle connector are easily damaged, affecting the normal operation of the cleaning machine. This is especially true when the handle connector is difficult to disassemble, often leading to increased maintenance costs. To solve this problem, a structure with a detachable and replaceable handle connector has emerged on the market. However, since the handle connector and the cleaning body have interconnected pipes, when the handle connector is disassembled, the pipes are disconnected, and water remaining in the pipes can easily seep out from the cleaning machine body. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of existing technologies where water easily leaks after the handle tube is disassembled, and provides an internal cleaning pipeline structure for a cleaning machine that is less prone to water leakage after the handle tube is disassembled.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An internal cleaning pipeline structure for a cleaning machine includes a cleaning body and a handle connector. A connecting block is fitted onto the handle connector, and a connecting sleeve is fixed to the side wall of the connecting block. The connecting sleeve is located on the side of the handle connector. A delivery hose is located inside the handle connector. One end of the connecting sleeve is located inside the connecting block and is sealed to the delivery hose, while the other end of the connecting sleeve is located outside the connecting block. A connector is detachably connected inside the cleaning body. The handle connector is detachably connected to the cleaning body after mating with the connector via the connecting block. One end of the connector is located on the end face of the cleaning body and has a slot that matches the end of the connecting sleeve located outside the connecting block. The connecting sleeve and the slot are sealed and pluggable. The device includes a conveying pipeline, one end of which is connected to a clean water tank. The other end of the connector is located inside the cleaning body and has a plug groove that matches the other end of the conveying pipeline. The open end of the plug groove is detachably and sealed to the conveying pipeline. The bottom of the plug groove has a through hole that communicates with the inside of the slot. A water-stop block is installed in the through hole. One end of the water-stop block is located in the plug groove and is elastically connected to the end of the conveying pipeline. Under elastic action, the water-stop block abuts against the bottom of the plug groove and is sealed to the through hole. The other end of the water-stop block passes through the through hole and is located in the slot, contacting the end of the connecting sleeve located outside the connecting block. The side wall of the other end of the water-stop block has an open groove that communicates with the inside of the connecting sleeve.

[0007] A connecting block is fitted onto the handle connector, and a connecting sleeve is fixed to the side wall of the connecting block. The connecting sleeve is located on the side of the handle connector. A delivery hose is provided inside the handle connector. One end of the connecting sleeve is located inside the connecting block and is sealed to the delivery hose, while the other end of the connecting sleeve is located outside the connecting block. A connector is detachably connected inside the cleaning body. The handle connector is detachably connected to the cleaning body after mating with the connector via the connecting block. One end of the connector is located on the end face of the cleaning body and has a slot that matches the end of the connecting sleeve located outside the connecting block. The connecting sleeve and the slot are sealed and pluggable. A delivery pipeline is provided inside the cleaning body. One end of the connector is connected to a clean water tank, and the other end of the connector is located inside the cleaning body and is provided with a plug groove that matches the other end of the delivery pipeline. The open end of the plug groove is detachably and sealed to the delivery pipeline. The bottom of the plug groove is provided with a through hole that communicates with the inside of the slot. A water-stop block is provided in the through hole. One end of the water-stop block is located in the plug groove and is elastically connected to the end of the delivery pipeline. Under the elastic action, the water-stop block abuts against the bottom of the plug groove and is sealed to the through hole. The other end of the water-stop block passes through the through hole and is located in the slot, and contacts the end of the connecting sleeve located outside the connecting block. The side wall of the other end of the water-stop block is provided with an open groove that communicates with the inside of the connecting sleeve. When the handle connector is connected to the cleaning body, it is attached to the cleaning body by engaging the connector and fitting the connector. At the same time, the end of the connecting sleeve outside the connecting block is inserted into the slot for a sealed connection. Overcoming the elastic effect, the water-stopping block is pushed a certain distance towards the inside of the cleaning body. At this time, the water in the delivery pipeline enters the insertion groove, and then flows into the delivery hose through the opening groove and the connecting sleeve in sequence, realizing the connection of the water path and facilitating the cleaning function of the floor brush. When it is necessary to separate the handle connector from the cleaning body, the connecting block is separated from the cleaning body. At the same time, the connecting sleeve is also separated from the slot. At this time, the water-stopping block moves in the opposite direction under the elastic reset action until it abuts against the bottom of the insertion groove and seals the through hole, thus achieving the purpose of preventing water leakage after the handle connector is disassembled.

[0008] Preferably, a connecting seat is provided at the open end of the insertion slot, the connecting seat is sealed to the insertion slot, one end of the connecting seat is located outside the insertion slot and is sealed to the conveying pipeline, the other end of the connecting seat is located inside the insertion slot and is provided with an installation groove, the bottom of the installation groove is provided with a water passage hole connected to the conveying pipeline, a spring is provided in the installation groove, and the connecting seat is elastically connected to the end of the water-stop block located inside the insertion slot through the spring, and a water passage gap is formed between the open end of the installation groove and the water-stop block. The connector and the opening of the insertion slot are sealed together, ensuring that water from the delivery pipeline enters the insertion slot through the connector without leaking out from the opening of the insertion slot, thus protecting other components inside the cleaning unit. Simultaneously, the connector facilitates the installation of the spring, enabling an elastic connection between the delivery pipeline and the water-stop block. This allows the water-stop block to reseal the through-hole under the elastic action of the spring after the handle connector is disassembled, preventing water leakage. A water passage gap is formed between the opening of the mounting slot and the water-stop block, allowing water to flow through when the spring is compressed, and then through the opening slot and connecting sleeve into the delivery hose.

[0009] Preferably, a sealing gasket is fitted onto the water-stop block. Under the elastic action of the spring, the water-stop block abuts against the bottom of the insertion groove through the sealing gasket and is sealed to the through hole. When the handle connector is connected to the cleaning body, the connecting sleeve overcomes the elastic action and pushes the water-stop block a certain distance toward the interior of the cleaning body, after which the sealing gasket separates from the bottom of the insertion groove, facilitating the passage of water. When the handle connector is separated from the cleaning body, under the restoring action of the spring, the water-stop block abuts tightly against the bottom of the insertion groove through the sealing gasket, sealing the through hole. The structure is simple and easy to operate.

[0010] Preferably, the outer diameter of the end of the water-stop block located within the slot is larger than the inner diameter of the connecting sleeve. This allows the connecting sleeve to act on the water-stop block and push it to move.

[0011] Preferably, a sealing ring is fitted onto the side wall of the connecting sleeve located outside the connecting block, and the connecting sleeve is sealed to the slot through the sealing ring. When water flows into the connecting sleeve through the opening groove, it prevents water from seeping out from the outside of the connecting sleeve, thereby improving water utilization.

[0012] Preferably, the delivery pipeline includes a connecting hose, a clean water tank connector, a water pump, a heating element, and a pressure relief valve. The clean water tank connector, water pump, heating element, and pressure relief valve are all detachably connected to the cleaning body. The clean water tank connector, water pump, heating element, and pressure relief valve are connected in series via the connecting hose and then connected to the insertion slot.

[0013] Preferably, the connecting block has snap-fit ​​buttons on both its left and right edges. These snap-fit ​​buttons are rotatably connected to the connecting block while also being elastically connected. The cleaning body has two slots that match the snap-fit ​​buttons one by one. The connecting block is detachably connected to the cleaning body via the snap-fit ​​buttons matching the corresponding slots. This snap-fit ​​button-slot connection method offers advantages such as simple structure, cost savings, ease of operation, and convenient and quick installation and removal of the handle connector from the cleaning body.

[0014] Preferably, the connector is a one-piece structure, with a socket at its center that matches the handle tube, and the slot located on the side of the socket. One end of the handle tube matches the socket, and the other end of the handle tube is often connected to the handle via a flexible tube. Compared to a structure with two separate components for the socket and slot, the one-piece structure of the connector is more stable and reliable.

[0015] The beneficial effects of this utility model are: when the handle connector is separated from the cleaning body, it achieves the purpose of preventing water leakage after disassembly; the sealing connection between the connecting seat and the opening end of the insertion slot helps protect other components inside the cleaning body; the connecting seat facilitates the installation of the spring, realizing an elastic connection between the delivery pipeline and the water-stop block; a water passage gap is formed between the opening end of the installation slot and the water-stop block, facilitating the passage of water when the spring is compressed; the structure is simple and easy to operate; it helps improve water utilization; the snap-fit ​​connection method, on the one hand, simplifies the structure and helps save costs, and on the other hand, the installation and disassembly of the handle connector and the cleaning body are convenient and quick; compared with the structure of setting two parts for the insertion port and the slot respectively, the integrated joint structure is more stable and reliable.
