[0025] A hand-held oil can oil filling nozzle, such as Figures 1-4 As shown, mainly used for auxiliary hand-held oil can temporary refueling of automobile fuel tank, the structure includes outer sleeve 1 and inner sleeve 2, the inner and outer sleeve is made of plastic material injection molding, the embodiment shown in Figure 1 As shown, the left side of the view as the front end or front side of the oil filling nozzle, the right side of the view as the rear end or rear side of the oil filling nozzle.

[0026] The outer sleeve 1 is composed of a rear cylinder 101, a front cylinder 102 with a smaller outer diameter than the rear cylinder, and a cone cylinder 103 connecting the rear cylinder and the front cylinder, respectively. The rear cylinder 101 and the front cylinder 102 are both cylindrical, and the front cylinder is bent relative to the rear cylinder. The corresponding cone cylinder 103 is a conical cylinder, and a limiting block 13 is provided on the outer surface of the outer sleeve 1. Specifically, the limiting block is provided between the front cylinder 102 and the cone cylinder 103. In this embodiment, two positionally symmetrical limiting blocks 13 are provided, which are integrally injection molded with the outer sleeve 1. The main purpose is to limit the insertion position of the front end of the outer sleeve when the front end of the outer sleeve is inserted into the automobile fuel tank for refueling. That is, the front end of the outer sleeve is in the most suitable refueling position in the automobile fuel tank.

[0027] The outer sleeve 1 is provided with an oil filling channel 11 and an air exchange channel 12. As shown in the Figure 1 The oil filling channel 11 is formed by penetrating along the axis of the outer sleeve, and the air exchange channel 12 with a smaller hole diameter is provided on the inner wall of the oil filling channel. Moreover, the oil filling channel 11 is formed by penetrating from the front end of the outer sleeve for oil filling, and the air exchange channel 12 is formed by penetrating from the front end of the outer sleeve for air exchange. A connecting hole 15 is provided in the outer sleeve 1 to communicate with the air exchange channel 12.

[0028] The inner sleeve 2 is also a cylindrical cylinder, and an oil inlet channel 21 and an air inlet channel 22 are provided in the inner sleeve 2. As shown in the Figure 1 The oil inlet channel 21 is formed by penetrating along the axis of the inner sleeve 2, and the air inlet channel 22 with a smaller hole diameter is provided on the inner wall of the oil inlet channel. The air inlet channel is penetrated from the rear end of the inner sleeve 2 to facilitate air intake.

[0029] The rear end of the inner sleeve is mounted on the hand oil can, that is, the connecting disc 25 integrally formed by the rear end of the inner sleeve is mounted on the mouth of the hand oil can (not shown in the figure), and the oil inlet channel 21 is in communication with the inside of the hand oil can; the outer surface of the front end of the inner sleeve is provided with an oil inlet hole 23 communicating with the oil inlet channel 21 and an air inlet hole 24 communicating with the air inlet channel 22. The oil inlet hole 23 can be a plurality of long circular holes, and the air inlet hole 24 can be a circular hole.

[0030] The front end of the inner sleeve can be sealingly inserted into the rear end of the outer sleeve 1 and move directionally, and the specific structure is that the front end of the inner sleeve is provided with two fixed sealing rings 3, so that the front end of the inner sleeve is sealingly inserted into the rear end of the outer sleeve 1 through the two sealing rings 3 to form a dynamic sealing contact, and the oil inlet hole 23 and the air inlet hole 24 on the outer surface of the front end of the inner sleeve are arranged between the two sealing rings 3.

[0031] At the same time, the outer sleeve 1 is provided with an injection-molded guide seat 14 and a guide hole 141 arranged on the guide seat, and the front end of the inner sleeve is provided with a guide rod 26 extending forward along the axis of the inner sleeve, so that the inner sleeve 2 is movably arranged in the guide hole 141 through the guide rod 26, and moves directionally in the rear end of the outer sleeve 1.

[0032] The guide rod 26 and the guide hole 141 are non-circular rods and non-circular holes that limit mutual rotation, such as the rectangular rods and rectangular holes selected in the embodiment. The design purpose of this structure is to limit the mutual rotation of the guide rod 26 relative to the guide hole 141, and then limit the mutual rotation of the inner sleeve 2 in the outer sleeve 1, and finally to ensure that the air inlet hole 24 can always be in a straight line moving position in the direction of the inner sleeve 2.

[0033] Then, the end of the guide rod 26 needs to be provided with a detaching piece 27, which limits the guide rod 26 from detaching from the guide hole 141, that is, prevents the inner sleeve 2 from falling off the rear end of the outer sleeve 1. The embodiment mainly adopts a tapered structure of the detaching piece 27, that is, the detaching piece can easily move forward and penetrate into the guide hole 141, but it is difficult to move backward and detach from the guide hole 141.

[0034] Thus, only the front end of the outer sleeve 1 is inserted into the oil tank of the car, and is resisted by the two limiting blocks 13, and then the front end of the inner sleeve 2 is moved in direction and is shrunk into the rear end of the outer sleeve 1 by the hand oil can, so as to drive the oil inlet hole 23 to be connected with the oil filling channel 11 and the air inlet hole 24 to be sealed and connected with the air exchange channel 12, at this time, the oil inlet channel 21, the oil inlet hole 23 and the oil filling channel 11 are sequentially connected to form oil filling, and the air inlet channel 22, the air inlet hole 24, the connecting hole 15 and the air exchange channel 12 are sequentially connected to form oil filling and air exchange.

[0035] The internal elastic structure refers to the reset spring 4 sleeved outside the guide rod 26, and the two ends of the reset spring are elastically pushed against the guide seat 14 and the front end of the inner sleeve respectively, so that the front end of the inner sleeve is automatically moved in direction and is extended into the rear end of the outer sleeve 1 under the elastic pushing of the reset spring 4 in normal state, that is, the oil inlet channel 21, the oil inlet hole 23 and the oil filling channel 11 cannot be connected in normal state, and only the front end of the inner sleeve 2 is moved in direction and is shrunk into the rear end of the outer sleeve 1 by the hand oil can to overcome the elastic pushing force of the reset spring 4 during the oil filling process, so as to connect all the oil channels, and thus the whole oil filling process is more safe, fast and convenient.

[0036] The above is only a specific embodiment of the present application, and those skilled in the art should understand that any equivalent structural design of the embodiment should be included in the protection scope of the present application.
