An elongated sprayer

Abstract

This application discloses an extended sprayer, belonging to the technical field of spraying devices. It provides an extended sprayer that is simple to operate and can spray over both short and long distances. The sprayer includes an extended connecting tube, one end of which is connected to an extension handle, and the other end to a pressurizer. The main body of the extended connecting tube is a spiral elastic tube. The extension handle includes a handle portion, one end of which is sealed to the spiral elastic tube, and the other end is a spray head. The handle portion has an inner end with external threads on its outer surface. One end of the spiral elastic tube has a first connecting sleeve. This application, through the design of the spiral elastic tube structure, allows the sprayer's infusion tube to automatically retract in the relaxed state, occupying less space. When long-distance spraying is required, it can extend considerably without needing to move a bulky infusion dispenser, making operation more labor-saving. The relatively shorter extension handle portion allows for more flexible and free spraying operations in confined spaces.

Description

Technical Field

[0001] This application relates to the field of spraying device technology, and more particularly to an extended sprayer. Background Technology

[0002] To improve the flexibility of spraying operations, a hose is usually connected between the liquid dispenser and the spray head. Although the hose can change its extension direction, its extension length is difficult to change. For spraying areas that are far away, it can only be achieved by moving the bulky liquid dispenser, which is quite troublesome to operate. Summary of the Invention

[0003] The purpose of this application is to provide an extended sprayer that is easy to operate and can spray in both near and far areas.

[0004] To achieve the above objectives, this application provides an extended sprayer: including an extended connecting tube, one end of which is connected to an extension handle, and the other end is adapted to connect to a pressurizer. The main body of the extended connecting tube is a spiral elastic tube, and the extension handle includes a hand-held portion. One end of the hand-held portion is sealed to the spiral elastic tube, and the other end is a spray head used to refine the liquid flow into finer droplets, producing a mist with a larger spray area.

[0005] As a preferred embodiment, the handheld part has an embedded end, the outer surface of the embedded end has an external thread, one end of the spiral elastic tube has a first connecting sleeve, the inner wall of the first connecting sleeve has an internal thread, which is suitable for engaging with the external thread of the embedded end, thus taking into account both connection stability and airtightness.

[0006] As a preferred embodiment, the embedded end and the handheld part also have a screw-on handle, and the larger diameter makes it easier to rotate the embedded end.

[0007] As a preferred embodiment, the diameter of the engagement handle is equal to the diameter of the first connecting sleeve, so that after the inner end engages with the first connecting sleeve, the end of the engagement handle is exactly aligned with the end face of the first connecting sleeve.

[0008] As a preferred embodiment, the outer surface of the first connecting sleeve is provided with a first friction groove to increase the contact friction force when the finger rotates the first connecting sleeve.

[0009] As a preferred embodiment, the outer surface of the screw-on handle is also provided with a second friction groove, which is also used to increase the friction force when in contact with the fingers.

[0010] As a preferred embodiment, the other end of the spiral elastic tube has a second connecting sleeve, which is adapted to connect to the output end of the pressure injector, thereby providing pressurized liquid flow to the spray head.

[0011] As a preferred embodiment, the inner wall of the second connecting sleeve has internal threads, and the outer surface of the second connecting sleeve is provided with a first friction groove, which can effectively reduce slippage and improve the efficiency of disassembly and assembly operations.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a spiral elastic tube structure, the sprayer’s infusion tube automatically retracts in the relaxed state, taking up less space. When long-distance spraying is required, it can extend for a relatively long time without having to move the bulky infusion dispenser, making it easier to operate.

[0014] (2) By designing a shorter extension handle, it is more flexible and convenient to use when spraying in narrow spaces. Attached Figure Description

[0023] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] like Figure 1-5 The extended sprayer shown includes an extended connecting tube 1, one end of which is connected to a rigid extension handle 2. The main body of the extended connecting tube 1 is a spiral elastic tube 103. In the relaxed state, the spiral elastic tube 103 is coiled up with its outer wall tightly against the tube. The extension handle 2 includes a handle portion 201, one end of which is sealed to the spiral elastic tube 103. Specifically, the handle portion 201 has an inner end 205, the outer surface of which has external threads. One end of the spiral elastic tube 103 has a first connecting sleeve 101, the inner wall of which has internal threads, which fit perfectly against the outer surface of the inner end 205. The threaded fit ensures both connection stability and sealing. The inner end 205 and the handheld part 201 are also connected by a coaxial screw-on handle 203 with a larger diameter. The diameter of the screw-on handle 203 is equal to the diameter of the first connecting sleeve 101, and their end faces can be aligned. The outer side of the first connecting sleeve 101 is provided with a first friction groove 104 to increase the rotational friction of the first connecting sleeve 101. The outer side of the screw-on handle 203 is also provided with a second friction groove 204 to increase the rotational friction of the screw-on handle 203. The other end of the handheld part 201 is a spray head 202, which can refine the liquid flow into liquid droplets to achieve an atomization effect.

[0026] The other end of the extension connecting tube 1 is used to connect to the pressure booster, which is used to increase the pressure of the liquid that needs to be atomized. Specifically, the other end of the spiral elastic tube 103 has a second connecting sleeve 102, which is used to connect to the output end of the pressure booster. In order to ensure connection stability and airtightness, the inner wall of the second connecting sleeve 102 also has an internal thread, which is matched with the external thread of the output end of the pressure booster. The outer side of the second connecting sleeve 102 is provided with a first friction groove 104, which is used to increase the friction of rotating the second connecting sleeve 102 and reduce slippage during disassembly and assembly.

[0027] Working principle: Both the extension connecting tube 1 and the extension handle 2 are made of plastic. The difference is that the extension handle 2 is made of a harder material and is less prone to deformation. The first connecting sleeve 101 and the second connecting sleeve 102 of the extension connecting tube 1 are also relatively hard and are not prone to deformation. However, the larger spiral elastic tube 103 is elastic and prone to elastic deformation. When a longer sprayer is not needed, the handle 201 is relaxed, and the outer surfaces of the spiral elastic tube 103 move closer together under its own elastic force, thus bringing the first connecting sleeve 101 and the second connecting sleeve 102 closer together. When a longer sprayer is needed, simply pull the handle 201 to overcome the elasticity of the spiral elastic tube 103, causing the outer surfaces of the spiral elastic tube 103 to move away from each other, thus increasing the distance between the first connecting sleeve 101 and the second connecting sleeve 102. With the positions of the liquid storage tank and the pressurizer unchanged, the spray head 202 of the handle 201 can spray from a greater distance, eliminating the need to carry the heavy liquid storage tank and pressurizer, making operation more labor-saving and convenient.

[0028] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application.
