Description

Technical Field

[0001] This utility model relates to the technical field of relay dust removal devices, specifically to a relay dust removal device. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in an electrical output circuit when the input quantity changes to a specified value. It has an interactive relationship between the control system and the controlled system and is commonly used in automated control circuits. Relays are usually soldered onto a circuit board, and when they are repaired, an air gun is needed to clean the dust off their exterior. Chinese patent CN212725162U discloses a dust removal device for relays, including a first frame, a second frame disposed within the inner cavity of the first frame, four sealing plates fixedly connected in a rectangular array at the top and bottom of the first and second frames, sealing gaskets fixedly connected to the bottom of the first and second frames, an air inlet pipe fixedly sleeved on the middle of one side of the first frame, a valve disposed on the outer wall of the air inlet pipe, multiple nozzles fixedly sleeved at equal intervals on the inner wall of the second frame, and a third frame disposed on the top of the first frame, with multiple filter screens disposed at equal intervals within the inner cavity of the third frame. This utility model utilizes the arrangement of a third frame, which, together with the second frame and the sealing gasket, forms a sealed space. This allows the filter to trap dust during relay cleaning and maintenance, preventing dust from flying around with the airflow and thus improving the relay's dust removal performance.

[0003] The existing technology has the following drawbacks: When cleaning a relay, the first and second frames must be completely covered outside the relay for blowing, and the dust blown out accumulates directly inside the first frame, requiring subsequent cleaning, which is quite troublesome. Therefore, a relay dust removal device is provided to solve the above problems. Utility Model Content

[0004] To address the problems mentioned above, the present invention provides a relay dust removal device comprising: a base, an air tank mounted on the upper end of the base, a vacuum cleaner positioned on one side of the air tank on the upper end of the base, and an air supply end of the air tank connected to a dust blowing head via a pipe. A suction pipe is slidably fitted onto the outer circumference of the dust blowing head, and a suction chamber is formed inside one end of the suction pipe, with a suction hood connected to the end of the suction pipe located within the suction chamber.

[0005] As a preferred technical solution of this utility model, the dust collection hood is provided with bristles at the end, the dust blowing pipe is fixedly connected to the head and tail of the dust collection pipe, and a U-shaped rod is fixedly connected to the outer side of the end of the dust collection pipe near the handle.

[0006] As a preferred technical solution of this utility model, the dust blowing head is provided with a limiting plate on the outer side of one end of the U-shaped rod, the limiting plate and the inside of the handle are slidably connected to the U-shaped rod, and a protective sleeve is sleeved on one end of the U-shaped rod.

[0007] As a preferred embodiment of this utility model, the blower head is fitted with a spring between the suction pipe and the limiting plate, and a suction connector is connected to the lower side of one end of the suction pipe, which is in communication with the inside of the suction chamber.

[0008] As a preferred technical solution of this utility model, the dust blowing head is connected to a blowing connector at one end of the limiting plate, and the blowing connector is in communication with the inside of the dust blowing head.

[0009] As a preferred embodiment of this utility model, an air pump is installed at the top of one end of the gas storage tank, and a pressure gauge is installed on one side of the upper end of the gas storage tank.

[0010] This utility model has the following advantages: the dust can be blown away by simply holding the handle and lifting the blower head, aiming it at the relay. The dust blown away can be sucked into the vacuum cleaner through the dust suction hood, which is convenient and quick. The distance between the dust suction hood and the blower head can be adjusted by simply pressing the U-shaped rod with your finger, which makes it easy to blow away dust in different locations.

Detailed Implementation

[0015] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figures 1-3 This utility model discloses a relay dust removal device, comprising: a base 1, an air tank 2 mounted on the upper end of the base 1, a vacuum cleaner 3 disposed on one side of the air tank 2 on the upper end of the base 1, and an air supply end of the air tank 2 connected to a dust blowing head 4 via a pipe. A suction pipe 5 is slidably sleeved on the outer circumference of the dust blowing head 4, and a suction chamber 501 is opened inside one end of the suction pipe 5. A suction hood 6 is connected to the end of the suction pipe 5 located in the suction chamber 501.
