New description: [New technical field] This creation is about the design of a spray gun, especially a fluid injection device that sprays mixed fluid. [Prior Art] Various spray guns are widely used to remove ash and dirt on the surface of objects, water spray, spray paint, and various other uses. This type of spray gun sprays a high-pressure fluid to remove ash and dirt, or uses high-pressure fluid mixed with water or other spray to spray and paint. As shown in Fig. 1, it is a perspective view showing a conventional squirting. In the conventional spray gun A, a high pressure fluid G is introduced from a control handle A1. The high-pressure fluid G is sent to a fluid nozzle A3 at the front end of the spray A through a fluid delivery pipe A2, and then ejected from the fluid nozzle A3. The fluid nozzle A3 is disposed with a small diameter pipe body A4. When the high pressure fluid G is ejected from the fluid nozzle A3, a Venturi effect is generated at the nozzle to make one of the water storage containers A5. The spray liquid L is ejected outward through the transport pipe body A4. In order to make the spraying effect uniform, the fluid nozzle A3 is manufactured to be curved and to be driven to rotate. The transport tube A4 is located in the fluid nozzle A3 and is made of a flexible material which can be bent and deformed in accordance with the rotation of the fluid nozzle A3. Therefore, the mixed fluid of the high pressure fluid G and the liquid discharge L is uniformly discharged in all directions in accordance with the rotation of the fluid nozzle A3. However, since the conveying pipe body A4 is broken with the fluid nozzle A3 or broken due to fatigue of the material as the usage time increases, the service life is shortened, and the member is often replaced. [New content] 3 The technical problems to be solved by this creative game are as described above. The conventional spray blast has a short service life, and it is necessary to replace parts frequently, which causes inconvenience in use. Therefore, the purpose of this creation is to provide a fluid ejection device, J structure with a dazzling material (4) raw material, sigh its life life without the need to replace the components from time to time. Technical Solution for Solving the Problem The present invention is a technical means for solving the problems of the prior art. The fluid-injecting device includes a fluid that is disposed in the axial direction of the flow = difficult I body =: The delivery body body has an interconnected-wheeling section and an outer-section section of the fluid delivery tube body to supply a source-connected fluid input tube body, fluid delivery=medium, and a-wheeling tube Body, the conveying pipe body is used for connection with the office:::, in the fluid conveying pipe body _ valley between the two phases of the mechanism Μ I from the L35 of the ^ and the external pendulum output section of the body - output The end is self-fluid conveying pipe, the transmission is placed in the difficult section or extends adjacent to the section of the reduced diameter section (four). In one embodiment of the present creation, the constricted section is outwardly expanded and the output section is gradually expanded. The pipe diameter is made from the conveying zone. In the creation of the 1st, the conveying pipe, such as the “hard material”, is created in the embodiment _ and the fluid wheeling pipe Connect the conveying section. Between π and ',,, and independent members, between the reduced diameter sections, the above-mentioned contraction (fourth) section and the wheeling section are applied in the first creation, and the (four) connection section is the thread M413547 connection section. In one embodiment of the present invention, the fluid input tube body is disposed in one of the fluid ejection devices to control the handle. In one embodiment of the present invention, the control handle is further provided with an adjustment mechanism for regulating the fluid input from the fluid input tube. The effect of the present invention against the prior art By the technical means employed in the present creation, in the fluid ejection device of the present invention, the delivery tube body is not in direct contact with the fluid delivery tube body, so there is no friction between the two. Furthermore, the conveying pipe body does not need to be bent and deformed as the fluid conveying pipe body rotates. Therefore, the conveying pipe body is not easily worn or fatigued and broken, and the service life can be prolonged without replacing the components from time to time. Specific embodiments of the present invention will be further illustrated by the following examples and the accompanying drawings. [Embodiment] Please refer to FIG. 2, FIG. 3, FIG. 4, and FIG. 5, and FIG. 2 is a perspective view showing an embodiment of the present invention, and FIG. 3 is a cross-sectional view showing the second drawing. 4 is a partial enlarged view of FIG. 3, and FIG. 5 is a partially enlarged cross-sectional view showing another embodiment of the present creation. A fluid ejection device 1 according to one embodiment of the present invention includes a body 1. One end of the body 1 is provided with a head 11 and the other end is provided with a control handle 12, and a fluid receiving mechanism 13 is coupled below the body 1. A fluid delivery tube 2 is provided in the body 1 of the fluid ejection device 100. The fluid delivery tube 2 is coupled to the body 1 through a bearing 20 and is rotatable along the axial direction within the fluid ejection device 100. The fluid delivery 5 M413547 can be rotated in a variety of configurations, such as combining a fluid delivery tube 2 with a motor, a fan, or other mechanism. However, the present invention is not limited thereto, and any structure that enables the fluid transport tube 2 to rotate can be used. The fluid delivery tube body 2 has a delivery section 21, an outer swing output section 22, and a reduced diameter section 23. The conveying section 21 is connected to a fluid input pipe 121 provided in the control handlebar 12. The fluid input tube body 121 is for connection with a fluid supply source (not shown) such that a fluid F1 from the fluid supply source can be input into the fluid delivery tube body 2 via the fluid input tube body 121. In addition, an adjustment mechanism 122 is also provided in the control handle 12. The adjusting mechanism 122 functions as the same valve, and can regulate the flow rate of the fluid F1 input from the fluid input pipe body 121 or close it so that the fluid F1 cannot be input into the fluid conveying pipe body 2. The oscillating output section 22 is connected to the conveying section 21, and the oscillating output section 22 is provided in the head 11 of the body 1 and has a curved configuration. Thereby, as the fluid transport tube 2 rotates, the fluid F1 input into the fluid transport tube 2 is ejected in various directions in accordance with the rotation angle of the outer swing output portion 22. The reduced diameter section 23 is connected between the conveying section 21 and the outer swing output section 22, and has a smaller diameter than the outer swing output section 22. In this implementation, the diameter of the reduced diameter section 23 tapers from the delivery section 21 toward the outer swing output section 22. However, the present creation is not limited thereto, and the diameter of the conveying section 21 may be larger than the diameter of the diameter reducing section 23. A conveying pipe body 3 is bored in the fluid conveying pipe body 2. One end of the conveying pipe body 2 is connected to the fluid accommodating mechanism 13 for conveying an accommodating fluid F2 accommodated in the fluid accommodating mechanism 13. The other end of the conveying pipe body 3 is an output end 31, and the output end 31 extends from the fluid conveying pipe body 2, 6 M413547, the conveying section 21 extends adjacent to the reduced diameter section 23 (Fig. 4) or extends in the reduced diameter zone. In paragraph 23 (figure 5). When the fluid F1 input into the fluid delivery tube body 2 flows through the reduced diameter section 23 of the fluid delivery tube body 2, a Venturi effect is generated at the output end 31 of the delivery tube body 3. By this effect, the accommodating fluid F2 accommodated in the fluid accommodating mechanism 13 is sucked into the conveying pipe body 3 by suction, and is output from the output end 31 of the conveying pipe body 3. Thereafter, the accommodating fluid F2 outputted from the output end 31 of the conveying pipe body 3 is mixed with the fluid F1 and ejected outward through the oscillating output portion 22. The position at which the output end 31 of the conveying pipe body 3 is disposed affects the generation of the Venturi effect, that is, the flow rate of the accommodating fluid F2 which is output from the output end 31 of the conveying pipe body 3. In order to adjust the flow rate of the accommodating fluid F2, in this embodiment, the reduced diameter section 23 of the fluid transport tube body 2 and the transport section 21 of the fluid transport tube body 2 are each a separate member, and the reduced diameter section The conveying section 21 is connected to the displacement 23 . Specifically, an adjustment connection portion 24 is provided between the reduced diameter section 23 and the conveying section 21. The adjustment joint 24 is in this embodiment a threaded connection. With this configuration, the position of the reduced diameter section 23 can be adjusted, thereby changing the relative position between the output end 31 of the transport tube body 3 and the reduced diameter section 23 of the fluid transport tube body 2. With the structure provided by the present invention, since the conveying pipe body 3 and the fluid conveying pipe body 2 are not in direct contact, there is no friction between the two, and the service life of the conveying pipe body 3 can be prolonged. Further, the conveying pipe body 3 does not need to be bent and deformed in accordance with the rotation of the fluid conveying pipe body 2, so that it can be made of a hard material to improve the structural strength of the conveying pipe body 3. It can be seen from the above embodiments that the fluid ejection device provided by the present invention has industrial utilization value, so the original operation has been in conformity with the requirements of the patent. However, the above description is only for the description of the preferred embodiment of the present invention. Anyone who is skilled in the art of 7 M413547 can make 2 specializations according to the above description, which is still the creative spirit of this creation...Si [Simple description Figure 1 shows a perspective view of a conventional spray blast; Figure 2 shows a perspective view of an embodiment according to the present creation; Figure 3 shows a cross-sectional view of Figure 2; Figure 4 shows a portion of Figure 3 Magnified view
