Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust collectors, more particularly, it relates to a flat suction structure with a lamp. BACKGROUND

[0002] As a common household cleaning appliance, the handheld dust collector is small in size, convenient to carry and use, and is more suitable for cleaning small spaces. The handheld dust collector needs to be connected to a dust collector flat suction for use, and the dust is sucked into the dust collector through the dust collector flat suction.

[0003] As Figure 17 The prior art flat suction structure with a lamp includes a flat suction, a flat suction cover plate, a flat suction support, a button, a PCB, and an LED lamp. The LED lamp is installed on the flat suction to improve the cleaning ability of the flat suction in shadow corners. The structure is simple, efficient, and low in cost.

[0004] However, the flat suction of the prior art flat suction structure with a lamp is usually in an integrated structure. To facilitate cleaning of gaps and corners, the flat suction channel is narrow, which is prone to blockage and is inconvenient to clean, affecting the normal use of the dust collector. In addition, the flat suction with an integrated structure design occupies a large area and is inconvenient to carry. SUMMARY

[0005] In view of the deficiencies of the prior art, the purpose of the present application is to provide a flat suction structure with a lamp. By controlling the sliding process of the two extension flat suction pieces along the guide piece, the flat suction pieces can be unfolded or folded, and the upper flat suction piece and the lower flat suction piece can be closed or separated. In the folded state, the upper flat suction piece and the lower flat suction piece are separated, which facilitates cleaning of the inside of the flat suction pieces and is convenient to carry.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0007] A flat suction structure with a lamp includes a connecting frame that is screw-connected to the suction end of a dust collector. The connecting frame includes a mounting shell. A support frame is fixedly installed inside the mounting shell.

[0010] The application is further provided with: the side surface of the half-connection pipe is screw-connected with a screw rod; one end of the screw rod is fixed with a connecting head, and the other end is rotatably provided with a square rod; the support frame includes a vertical rod fixedly installed between the inner walls of the air extraction pipe; the side surface of the vertical rod is fixed with an extension rod; the end of the extension rod is fixed with a sleeve slidably matched with the square rod; and the two ends of the sleeve are each fixed with a baffle.

[0011] The application is further provided with: the side surface of the half-inner flat suction pipe is symmetrically provided with a sliding groove; the extension flat suction piece includes a half-outer flat suction pipe; the inside of the half-outer flat suction pipe is provided with a sliding cavity slidably matched with the corresponding half-inner flat suction pipe; and the inner wall of the sliding cavity is symmetrically fixed with a sliding rail slidably matched with the corresponding sliding groove.

[0012] The application is further provided with: the guide piece includes two Z-shaped plates symmetrically arranged; the inside of the Z-shaped plate is provided with a Z-shaped guide groove; the Z-shaped guide groove includes a first straight guide groove and a second straight guide groove arranged in parallel with each other; and the first straight guide groove and the second straight guide groove are provided with an inclined guide groove therebetween.

[0013] The application is further provided with: the opposite side surfaces of the half-outer flat suction pipe are symmetrically fixed with an ear plate; the side surface of the ear plate is fixed with a sliding rod; and the sliding rod is slidably matched with the first straight guide groove, the second straight guide groove, and the inclined guide groove.

[0014] The application is further provided with: one group of Z-shaped plates in the same guide piece is fixedly installed with a piston cylinder at the end thereof, and the other group of Z-shaped plates is provided with an inclined guide plate slidably arranged through the surface thereof; the surface of the inclined guide plate is fixed with a cover plate matched with the sliding rod; and the cover plate and the surface of the corresponding Z-shaped plate are fixedly connected with a return spring.

[0015] The invention is further configured as follows: a piston block is slidably disposed inside the piston cylinder; a piston rod is fixed to the side of the piston block and slidably cooperates with the piston cylinder; a connecting spring sleeved on the piston rod is fixedly connected between the piston block and the piston cylinder; an air extraction branch pipe is connected to the end of the piston cylinder, and an exhaust branch pipe is connected to its peripheral side near its end; a sealing cap is screwed onto the air extraction branch pipe; the sealing plate has a hollow internal structure, and installation ports are opened on both opposite sides; an elastic diaphragm is disposed inside the installation port; sealing cavities adapted to the elastic diaphragm in the inflated state are symmetrically opened on both sides of the inner wall of the sealing groove; an air supply pipe communicating with the corresponding sealing plate is fixedly disposed through the outer wall of the semi-connecting pipe; the air supply pipe and the exhaust branch pipe are connected by a flexible hose.

[0016] The invention is further configured such that: a plurality of U-shaped grooves are evenly formed on the surface of the semi-outer flat straw; a plurality of rubber sealing rings adapted to the corresponding U-shaped grooves are fixed on the inner wall of the rubber sleeve; a plurality of straps are fixed on the bottom surface of the rubber sleeve; a rough surface layer is provided on the side of the straps; and a hook surface layer is provided on the side of the rubber sleeve.

[0017] The advantages of this invention are:

[0018] 1. This invention controls the two extended flat suction tubes to unfold or retract themselves as they slide along the guide, while simultaneously causing the upper and lower flat suction tubes to close or separate. When the two extended flat suction tubes are in the retracted state, the upper and lower flat suction tubes separate, which facilitates cleaning the inside of the upper and lower flat suction tubes and makes them easy to carry.

[0019] 2. In this invention, as the sliding rod slides inside the second straight guide groove, it slides and squeezes the corresponding piston rod, thereby driving the piston block to slide along the inner wall of the piston cylinder. The connecting spring is stretched, thereby sending the air inside the piston cylinder into the sealing plate through the exhaust branch pipe, hose, and air supply pipe in sequence. The air pressure inside the sealing plate increases, causing the elastic diaphragm to inflate and expand, blocking the sealing cavity and improving the sealing performance of the connection between the upper and lower flat suction parts.

[0020] 3. The present invention improves the sealing performance between the two halves of the outer flat straw in the closed state by placing a rubber sleeve on the two halves of the outer flat straw. This is achieved by attaching a rubber sleeve to the two halves of the outer flat straw in the closed state and then securing the rubber sealing ring to the two halves of the outer flat straw with a strap.
