Description

Technical Field

[0001] This utility model relates to the field of suction devices, and in particular to a multifunctional compressed air suction device. Background Technology

[0002] A vacuum cleaner is a tool that uses negative pressure to suck up or remove liquids, gases, particles, or other substances. It is widely used in medical, industrial, and household applications. Vacuum cleaners generate negative pressure mechanically, electrically, or manually, creating a pressure difference to adsorb or transfer substances. Their efficiency and applications depend on the vacuum level, suction port design, and the characteristics of the medium. A compressed air-powered vacuum cleaner is a device that uses compressed air to generate vacuum suction. High-pressure air enters the vacuum cleaner through the inlet, accelerates as it flows through the narrow nozzle, and forms a low-pressure zone at the outlet. This low-pressure zone connects to the external environment through the suction port, creating negative pressure inside the target container or pipe, thereby sucking up liquids, particles, or stationary objects.

[0003] Chinese Patent CN206463263U discloses a suction device that uses a spring to drive a piston or piston rod outward to generate suction. However, when changing suction heads for different purposes, the operation is complicated and inconvenient. Therefore, a multi-functional compressed air suction device is provided. Utility Model Content

[0004] The main purpose of this utility model is to provide a multi-functional compressed air suction device to solve the problem in related technologies where it is complicated and inconvenient to change suction heads for different purposes.

[0005] To achieve the above objectives, according to one aspect of this utility model, a multifunctional compressed air suction device is provided, including a connecting pipe, an outlet pipe fixedly installed on one side of the connecting pipe, a main pipe fixedly installed on the other side of the connecting pipe, a suction pipe fixedly installed at the other end of the main pipe, a plurality of telescopic grooves arranged in a ring array on the side wall of the suction pipe, a locking block slidably installed in the telescopic groove, a pressure groove opened on the upper surface of the locking block, and a plurality of connecting grooves connecting the telescopic grooves opened on the upper surface of the suction pipe, and further including: a pressure rod, the pressure rod being inserted into the connecting groove, the lower end of the pressure rod being inserted into the pressure groove, and the locking block being retracted by the pressure rod.

[0006] Furthermore, one end of the card block has an angled opening that slopes upwards and outwards towards the telescopic groove.

[0007] Furthermore, the pressure groove is an inclined groove that slopes downwards and outwards from the telescopic groove, and the lower end of the pressure rod is provided with an angle that fits tightly against the lower surface of the pressure groove.

[0008] Furthermore, an installation tube is snapped onto the outside of the straw, and a cover is fixedly installed on the lower surface of the installation tube.

[0009] Furthermore, a snap-fit ​​groove is provided on the inner arc wall of the installation tube. The snap-fit ​​groove has a ring structure. When the installation tube is installed onto the suction tube, the snap-fit ​​block snaps into the snap-fit ​​groove.

[0010] Furthermore, a pressure plate is fixedly installed on the upper surface of the pressure rod. The pressure plate has a ring structure, and a spring a is fixedly installed in the middle of the lower surface of the pressure plate. The lower end of the spring a is fixedly installed on the upper surface of the straw.

[0011] Furthermore, a spring b is fixedly installed on the inner wall of the telescopic groove, and the other end of the spring b is fixedly installed on one side of the locking block.

[0012] Furthermore, a cavity is provided inside the connecting pipe, and the connecting pipe has a tapered structure.

[0013] Furthermore, several air ducts are symmetrically fixedly installed at the arc wall of the connecting pipe.

[0014] Furthermore, the radius of the connecting pipe decreases from the main pipe to the outlet pipe.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This multi-functional compressed air suction device is equipped with a suction tube. The side wall of the suction tube has several telescopic grooves arranged in a ring array. A locking block is slidably installed in the telescopic groove. Several connecting grooves are opened on the upper surface of the suction tube, and a pressure rod is inserted into the connecting groove. A pressure groove is opened on the upper surface of the locking block. The pressure groove is an inclined groove that slopes downwards and outwards from the telescopic groove. The lower end of the pressure rod has an angle that fits against the lower surface of the inclined groove. A pressure plate is fixedly installed on the upper surface of the pressure rod.

[0030] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0031] This embodiment provides a multi-functional compressed air suction device, including a connecting pipe 1, an outlet pipe 12 fixedly installed on one side of the connecting pipe 1, a main pipe 14 fixedly installed on the other side of the connecting pipe 1, and a suction pipe 15 fixedly installed at the other end of the main pipe 14. The side wall of the suction pipe 15 has a plurality of telescopic grooves 151 arranged in a ring array. A locking block 16 is slidably installed in the telescopic groove 151. A pressure groove 161 is opened on the upper surface of the locking block 16. A plurality of connecting grooves 153 connecting the telescopic grooves 151 are opened on the upper surface of the suction pipe 15. It also includes a pressure rod 31, which is inserted into the connecting groove 153. The lower end of the pressure rod 31 is inserted into the pressure groove 161. The locking block 16 is retracted by the pressure rod 31.

[0032] like Figure 2 , Figure 4 , Figure 5 As shown, one end of the card block 16 is provided with an oblique angle that slopes upwards and outwards from the telescopic groove 151.

[0033] like Figure 5 , Figure 6 As shown, the pressure groove 161 is an inclined groove that slopes downwards and outwards from the telescopic groove 151. The lower end of the pressure rod 31 is provided with an angle that fits tightly against the lower surface of the pressure groove 161. The lower inclined surface of the pressure groove 161 is pressed by the angle at the lower end of the pressure rod 31, causing the locking block 16 to retract into the telescopic groove 151.

[0034] like Figure 1 , Figure 7 , Figure 8 As shown, an installation tube 2 is snapped onto the outside of the suction tube 15, and a cover 21 is fixedly installed on the lower surface of the installation tube 2. The cover 21 is a duckbill cover, and dust is suctioned through the cover 21.

[0035] like Figure 8 As shown, a snap-fit ​​groove 211 is provided on the inner arc wall of the installation tube 2. The snap-fit ​​groove 211 is a ring structure. When the installation tube 2 is installed on the suction tube 15, the snap-fit ​​block 16 is snapped into the snap-fit ​​groove 211 to fix the position of the installation tube 2.

[0036] like Figure 4 , Figure 6 As shown, a pressure plate 3 is fixedly installed on the upper surface of the pressure rod 31. The pressure plate 3 has a ring structure. A spring a32 is fixedly installed in the middle of the lower surface of the pressure plate 3. The lower end of the spring a32 is fixedly installed on the upper surface of the suction tube 15. In the initial state, the spring a32 is not compressed. The angled part of the pressure rod 31 is located in the pressure groove 161. When the pressure plate 3 is pressed down, the pressure plate 3 drives the pressure rod 31 to move downward and compress the spring a32. The angled part of the pressure rod 31 squeezes the lower inclined surface of the pressure groove 161 to drive the locking block 16 to retract into the telescopic groove 151. At this time, the spring b152 is compressed, and the installation tube 2 can be removed. When the pressure plate 3 is released, the spring a32 returns to its original position to drive the pressure plate 3 and the pressure rod 31 to move upward. The spring b152 returns to its original position to drive the locking block 16 to extend.

[0037] like Figure 4 , Figure 5 As shown, a spring b152 is fixedly installed on the inner wall of the telescopic groove 151. The other end of the spring b152 is fixedly installed on one side of the locking block 16. In the initial state, the spring b152 is not under force, and one end of the locking block 16 extends out of the telescopic groove 151. When the cover 21 is installed, when the suction tube 15 is inserted into the installation tube 2, the inner edge of the upper surface of the installation tube 2 presses the angled part of the locking block 16, causing the locking block 16 to retract into the telescopic groove 151, and at the same time compressing the spring b152. When the telescopic groove 151 is aligned with the locking groove 211, the spring b152 returns to its original position, thereby driving the locking block 16 to extend. The upper surface of the locking block 16 is in contact with the upper side wall of the locking groove 211 to fix the position of the installation tube 2.

[0038] like Figure 3 As shown, a cavity 11 is provided inside the connecting pipe 1, and the connecting pipe 1 has a conical structure;

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, several air ducts 13 are symmetrically fixedly installed at the arc wall of the connecting pipe 1. An air pump is fixedly installed at one end of the air duct 13, and the air pump delivers compressed gas into the cavity 11.

[0040] like Figure 1 , Figure 2 , Figure 3 As shown, the radius of the connecting pipe 1 decreases from the main pipe 14 to the outlet pipe 12. When the high-pressure gas enters, the flow rate is low. When the gas moves towards the outlet pipe 12, the pipe diameter decreases, the gas flow rate increases, and the gas pressure decreases, thereby sucking in the object through the suction pipe 15.

[0041] In practical use, when using the vacuum cleaner's dust extraction function, the cover 21 is installed on the suction tube 15. The cover 21 is snapped onto the suction tube 15 via the mounting tube 2. When the suction tube 15 is inserted into the mounting tube 2, the inner edge of the upper surface of the mounting tube 2 presses against the angled corner of the locking block 16, causing the locking block 16 to retract into the telescopic groove 151. At the same time, the spring b152 is compressed. When the telescopic groove 151 aligns with the locking groove 211, the spring b152 returns to its original position, causing the locking block 16 to extend. The upper surface of the locking block 16 fits against the upper side wall of the locking groove 211 to fix the position of the mounting tube 2, allowing dust to be extracted through the cover 21. When using the vacuum cleaner's water extraction function, the pressure plate 3 is pressed down, causing the pressure plate 3 to drive the pressure rod 3. 1. Move downward and compress spring a32. The angled part of the pressure rod 31 presses the lower inclined surface of the pressure groove 161, so as to drive the locking block 16 to retract into the telescopic groove 151. At this time, spring b152 is compressed, and the installation tube 2 can be removed. When the pressing plate 3 is released, spring a32 returns to its original position, so as to drive the pressure plate 3 and the pressure rod 31 to move upward. Spring b152 returns to its original position, so as to drive the locking block 16 to extend. The suction tube 15 is placed in the water tank to suck water. One end of the air pipe 13 is fixedly connected to the air pump. The air pump delivers compressed gas into the cavity 11. When the high-pressure gas enters, the flow rate is low. When the gas moves to the outlet pipe 12, the pipe diameter decreases, the gas flow rate increases, and the air pressure decreases, so as to suck the object through the suction tube 15.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
