Description

Technical Field

[0001] The utility model relates to a brush, in particular to a long-handled durable cleaning brush. Background Art

[0002] Currently, a Chinese patent with authorization announcement number CN220512404U discloses a cleaning brush including a brush and tweezers. The brush includes a brush head and a connecting portion fixed to each other, and the tweezers can be detachably plugged and fixed to the connecting portion along the length direction of the brush.

[0003] By combining a brush and tweezers into a cleaning brush, the cleaning brush has two usage states: a detachable state and a snap-on state. In the detachable state, the tweezers can be used alone to achieve a clamping function. In the snap-on state, since the tweezers and the brush are plugged and fixed along the length of the brush, the tweezers can be used as a handle of the cleaning brush for the user to hold, thereby using the brushing function of the cleaning brush normally.

[0004] However, when people clean daily, they usually have to use detergent together to improve the cleaning effect. This requires people to carry a bucket of detergent in one hand and use a cleaning brush in the other hand to scrub, which is extremely inconvenient. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a long-handled durable cleaning brush to achieve the purpose of improving the convenience of use.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: a long-handled durable cleaning brush, comprising a brush handle and a brush head, the brush handle and the brush head being connected by a connecting structure, the brush head being connected with bristles, the brush head being provided with a connecting groove, the brush handle being provided with a storage cavity for placing detergent, the storage cavity being connected to the connecting groove, the side wall of the brush head being provided with a discharge hole connected to the connecting groove, the side wall of the brush handle being provided with a placement groove connected to the storage cavity, a pressure block being provided in the placement groove, and an elastic structure being provided between the pressure block and the brush handle.

[0007] To implement the above technical solution, the detergent is injected into the storage chamber, the brush head is connected to the brush handle through the connecting structure, and while holding the handle, pressure is applied to the pressing block with the fingers. The detergent is pressed from the storage chamber into the connecting groove and then discharged from the discharge hole. After releasing the pressing block, the pressing block is reset by the elastic structure, which greatly improves the convenience of the operation process.

[0008] As a preferred solution of the present utility model, the connecting structure includes an anti-drop hole, an elastic rod and an anti-drop block. The anti-drop hole is opened on the brush head and is connected to the connecting groove. One end of the elastic rod is fixed to the brush handle, and the other end is fixedly connected to the anti-drop block. The elastic rod extends into the connecting groove and the anti-drop block is embedded in the anti-drop hole.

[0009] To implement the above technical solution, move the brush head toward the brush handle, and the anti-drop block will be embedded in the anti-drop hole to connect the brush head and the brush handle. Apply pressure to the anti-drop block to make it fall out of the anti-drop hole, and then the brush head can be removed from the brush handle.

[0010] As a preferred solution of the present utility model, a guide tube is fixedly connected to the brush handle, the guide tube is communicated with the storage chamber, a sealing block is fixedly connected to the guide tube, a connecting hole is opened on the sealing block, a connecting membrane is arranged in the connecting hole, one end of the connecting membrane is connected to the sealing block and is used to seal the connecting hole.

[0011] To implement the above technical solution, pressure is applied to the pressing block. Through the action of the pressure, the detergent is squeezed out from the connecting hole and the connecting membrane is pushed open. The detergent enters the connecting groove and is then discharged from the discharge hole. When the pressing block is released, the connecting membrane automatically covers the connecting hole due to its own elastic force, so that the detergent is not easily discharged from the connecting hole.

[0012] As a preferred solution of the present utility model, a plunger is provided at the end of the brush handle away from the brush head, and the plunger blocks the end of the storage chamber. The plunger is provided with a sliding hole, and a sliding rod is slidably connected in the sliding hole. A push plate is threadedly connected to the sliding rod, and a sealing ring is provided between the outer wall of the push plate and the inner wall of the storage chamber. The sliding rod is connected to the plunger through a one-way component.

[0013] To implement the above technical solution, the plunger is removed from the brush handle to facilitate pouring the detergent into the storage chamber, and then the plunger is used to seal the end of the storage chamber. In the process of applying pressure to the pressure block, the sliding rod cannot move due to the one-way component, so that the detergent is smoothly squeezed out from the connecting hole; when the pressure block is released, the pressure block is reset by the elastic structure. Since the connecting film covers the connecting hole, the push rod is moved toward the pressure block due to the effect of negative pressure. Through the setting of the sealing ring, most of the detergent attached to the inner wall of the storage chamber is scraped off, reducing resource waste.

[0014] As a preferred solution of the present invention, the one-way structure includes a triangular ring groove, a mounting recess, a sliding plate, a spring sheet and a guide slope. A plurality of the triangular ring grooves are opened on the slide rod and are arranged along the length direction of the slide rod. The mounting recess is opened on the inner wall of the slide hole. The slide is slidably connected to the mounting recess. The spring sheet is placed in the mounting recess and one end is connected to the inner wall of the mounting recess, and the other end is connected to the slide. The guide slope is opened at the end of the slide away from the spring sheet and is used to interfere with the triangular ring groove.

[0015] To implement the above technical solution, the sliding plate continuously generates a force toward the sliding rod due to the elastic force of the spring sheet, and the sliding plate abuts against the inner wall of the triangular ring groove to achieve unidirectional movement of the sliding rod.

[0016] As a preferred solution of the present invention, a hanging hole is provided on the plunger.

[0017] The above technical solution is implemented to facilitate hanging the brush handle.

[0018] As a preferred solution of the present invention, the elastic structure includes a limiting groove and a U-shaped elastic plate. The limiting groove is opened on the inner wall of the storage cavity, the two ends of the U-shaped elastic plate are fixed in the limiting groove, and the middle part of the U-shaped elastic plate is connected to the pressure block.

[0019] To implement the above technical solution, pressure is applied to the pressing block, causing the U-shaped elastic plate to deform. When the pressing block is released, the U-shaped elastic plate recovers and the pressing block is reset.

[0020] As a preferred solution of the present invention, a protective film is fixedly connected to the side wall of the pressing block, and the protective film surrounds the placement groove.

[0021] By implementing the above technical solution, detergent is not easily overflowed from the gap between the pressing block and the placement groove, thus reducing resource waste. BRIEF DESCRIPTION OF THE DRAWINGS
