Description

cleaning device

The present invention relates to cleaning devices.

With the use or the passage of time, dust and dirt will continue to accumulate and adhere to various machines, mechanisms, and components, such as the engine room of a car. Since most vehicles travel outside for a long time, dust and sand in the environment are easy to stick to. Pipes sticking to the engine room, unexpected breakage or gaps will also cause oil spills and more dirt to stick, so regular cleaning and maintenance are required to ensure smooth operation.

However, there are many complicated pipelines hidden in the engine room of the car, and the gaps between the pipelines are small, which makes it very difficult to clean. Therefore, most cleaning operations are only to spray high-pressure gas from the spray gun to clean the surface, and cannot Internal or deep structures are cleaned.

Therefore, it is necessary to provide a novel and progressive cleaning device to solve the above-mentioned problems.

The main purpose of the present invention is to provide a cleaning device that can effectively penetrate into a narrow space or go deep into a deep cleaning operation.

To achieve the above object, the present invention provides a cleaning device, comprising: a pipe and a spray head. The pipe is used to receive and guide a fluid; the nozzle is detachably assembled to the pipe and connected to the interior of the pipe, the nozzle extends along an extension direction, and the nozzle is provided with at least one first nozzle for the fluid to discharge , the opening direction of the at least one first nozzle is transverse to the extension direction; wherein, the hardness of the nozzle is different from the hardness of the pipe; wherein, the hardness of the nozzle is smaller than the hardness of the pipe.

The following examples illustrate the possible implementation of the present invention, but are not intended to limit the scope of protection of the present invention. The "one" or "at least one" before the nouns mentioned in the text do not limit the number. It can also be "plural" according to the needs, and the change in the number is also within the scope of protection, which will be described first.

Please refer to FIG. 1 to FIG. 6 , which show an embodiment of the present invention. The cleaning device of the present invention includes: a pipe 1 and a nozzle 2 .

The pipe fitting 1 is used to receive and guide a fluid, such as liquid or gas. The nozzle 2 is detachably assembled to the pipe fitting 1 and communicates with the inside of the pipe fitting 1. The nozzle 2 extends along an extension direction 3. The nozzle 2 penetrates There is at least one first spout 21 for the fluid to leak out, and the opening direction of the at least one first spout 21 is transverse to the extension direction 3; wherein, the detachable structure is conducive to replacing new products, or changing different lengths as required The size or hardness of the nozzle 2, and if the pipe fitting 1 is already available in the predetermined construction site, the user only needs to carry the nozzle 2, which is extremely practical and portable.

In this embodiment, the pipe fitting 1 and the spray head 2 both extend in a straight line, and the flow mode of the fluid in the cleaning device is shaft-in and side-out, which is beneficial for lateral cleaning of dirt at different positions on the moving path, which is quite It is suitable for use in narrow spaces or long spaces, such as car engine compartments, filter elements, cooling fins, etc. Moreover, the ratio of the length of the pipe 1 to the length of the spray head 2 is preferably greater than 3, so as to be widely used in depth environments encountered in practice. In addition, the pipe member 1 can also be provided with at least one second nozzle 11 extending radially, and the at least one second nozzle 11 cooperates with the at least one first nozzle 21 to have different usage patterns, such as in the at least one first nozzle 21 One spout 21 and the at least one second spout 11 are arranged opposite to each other and can spray in two directions, and the at least one first spout 21 and the at least one second spout 11 are arranged in the same direction to have the effect of cleaning multiple times.

The hardness of the spray head 2 is preferably different from that of the pipe fitting 1 , and the detachable design allows the user to replace it according to different needs. For example but not limited to, if the structure of the object to be cleaned is more precise, since the nozzle 2 is located at the forefront and will touch the object first, at this time, the hardness of the nozzle 2 is selected to be smaller than the hardness of the pipe 1, such as the pipe 1 is a metal pipe, and the nozzle 2 is rubber to ensure that the collision of the nozzle 2 during the movement will not cause damage to the object. In this embodiment, the nozzle 2 is integrally formed, so that the nozzle 2 can maintain the basic Excellent structural strength, taking into account the two purposes of not being easily deformed and not being damaged by collisions.

More specifically, the spray head 2 includes an extension section 26 and a tapered section 27 connected to each other. The gap between the tapered section 27 and the extension section 26 is arc-shaped, and the structure of the tapered section 27 can move During the process, the obstacles are gradually pushed out, and the arc-shaped structure can ensure that the objects will not be damaged during the moving process. In this embodiment, the extension section 26 extends linearly to help the fluid flow smoothly, and the tapered section 27 is closed to reliably block the fluid in the axial direction, wherein the extension section 26 is far away from the tapered section. A portion of the narrowing section 27 is a connecting portion 261 , which is screwed to the pipe 1 , and a plurality of ribs 262 protrude from the connecting portion 261 to facilitate hand-held operation and rotation.

More specifically, the outer contour of the spray head 2 is non-circular. The spray head 2 includes two working surfaces 23. The two working surfaces 23 are connected to each other and have an included angle 24 between them. The included angle 24 is between 90 degrees and 160 degrees. Between them, the at least one first nozzle 21 is disposed through at least one of the two working surfaces 23 , so that the user can grasp the position of the at least one first nozzle 21 visually.

In this embodiment, one side of the extension 26 is provided with the two working surfaces 23, and the opposite side of the extension 26 is provided with a curved surface 25, and the two ends of the curved surface 25 are respectively connected to the two working surfaces. The surface 23, the curved surface 25 is beneficial to move in a sliding manner, and viewed from the cross-section of the extension section 26, the outer contours of the two working surfaces 23 and the curved surface 25 are fan-shaped. Moreover, the quantity of the at least one first nozzle 21 is plural, and the plurality of the first nozzles 21 are arranged at intervals along the extension direction 3, and the plurality of the first nozzles 21 are equally divided through the two working surfaces 23, so that The fluid can be evenly ejected from two different directions simultaneously, thereby increasing the cleanable area.

Preferably, the plurality of the first nozzles 21 have at least two diameters with different sizes, so as to provide different air volumes and wind speeds at different positions, and have multi-stage cleaning effects. In this embodiment, the plurality of first nozzles 21 closest to and farthest from the tube 1 in the extending direction 3 have the largest aperture size.

In another preferred embodiment, the spray head 2 defines a centerline 22 , and the plurality of first nozzles 21 are gradually expanded toward a direction away from the centerline 22 to expand the area of spraying area.

It should be added that although the pipe fitting 1 in this embodiment is a straight pipe, it is not limited to its form. As shown in another embodiment of FIG. 7, the pipe fitting 1A is a flexible bellows pipe. It can be applied in a more rugged environment through its flexible characteristics.
