[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 4 As shown, the present invention provides a portable multifunctional suction pump suitable for multiple media, including: a pump seat 1, a suction chamber structure 3 is fixedly connected to the top of the pump seat 1, a piston head 209 is slidingly and sealably connected inside the suction chamber structure 3, one end of the piston head 209 is transmission-connected to a pull-and-draw connecting rod group 2, the suction chamber structure 3 is connected to one end of a conveying pipeline through a piston water inlet head 302, the other end of the conveying pipeline is connected to a three-way water inlet head 109, an anti-backflow three-way structure 105 is also provided on the conveying pipeline, and a water outlet 107 is fixedly connected to the top of the anti-backflow three-way structure 105.

[0029] When the device is in use, first place the pump seat 1 on the ground, connect the water inlet pipe on the conveying pipeline, and connect it to the medium to be pumped. Then, by stepping on the pull-pull connecting rod group 2, the pull-pull connecting rod group 2 moves downward, and then pushes the piston head 209 to move along the suction chamber structure 3 to achieve the suction operation of the medium. The setting of the anti-backflow three-way structure 105 can prevent the liquid from flowing back and ensure that the liquid is discharged through the water outlet 107. Specifically, the anti-backflow three-way structure 105 is an anti-backflow three-way shuttle valve, which includes two spherical one-way valves. Among them, a one-way valve is also provided on the water outlet 107. The user can achieve the suction operation by stepping on the pedal multiple times. No electricity is required, the operation is simple, the structure is compact, and it is easy to carry. The suction capacity is strong and it is not easy to be damaged. It is very suitable for outdoor operations and has good practical value.

[0030] The present invention utilizes these structures to realize a portable multifunctional pumping pump suitable for multiple media, which is compact and easy to carry, simple in structure, easy to operate and maintain, and uses manual labor to perform pumping operations, thereby getting rid of the limitation of electricity.

[0031] According to a further optimization scheme, the suction chamber structure 3 includes a piston sleeve base 305, which is fixedly connected to the top of the pump seat 1, and the top of the piston sleeve base 305 is fixedly connected to the piston sleeve 301, and the inside of the piston sleeve 301 is fixedly connected to the piston cylinder 303, and the bottom end of the piston cylinder 303 is connected to the piston water inlet head 302.

[0032] To further optimize the solution, the pull-out connecting rod group 2 includes a fixed seat 210, which is fixedly connected to the top of the piston sleeve 301, and the two sides of the fixed seat 210 are rotatably connected with directional pedal structures, and the bottom end of the directional pedal structure is rotatably connected with a piston reset structure and a piston pushing structure, and the piston pushing structure is transmission-connected to the piston head 209.

[0033] Further optimized solution, the directional pedal structure includes a pedal 201, one side of the pedal 201 close to the fixed seat 210 is rotatably connected to one end of two pedal directional connecting rods 211, the other ends of the two pedal directional connecting rods 211 are rotatably connected to the fixed seat 210, and the two pedal directional connecting rods 211 are parallel to each other;

[0034] The bottom end of the pedal 201 is rotatably connected to one end of the first connecting rod 202, and the other end of the first connecting rod 202 is rotatably connected to the connecting rotating seat 204. The top end of the connecting rotating seat 204 is rotatably connected to the piston pushing structure, and the bottom end of the connecting rotating seat 204 is rotatably connected to the piston reset structure.

[0035] By setting two parallel pedal directional connecting rods 211, a parallelogram structure can be formed with the pedal 201 and the fixed seat 210, so as to limit the pedal 201 to always face upwards, which is convenient for pedaling. After the pedal 201 is stepped on, the pedal 201 drives the first connecting rod 202 and the connecting rotating seat 204 below it to move inward, thereby pushing the piston pushing structure and the piston reset structure to move inward, so as to achieve the mutual approach of the piston heads 209.

[0036] A further optimized solution is that the piston pushing structure includes a movable seat 205, one side of the movable seat 205 is rotatably connected to the connecting rotating seat 204 through a movable seat ear plate, the movable seat 205 is rotatably connected to one end of a piston rod 208, and the other end of the piston rod 208 is fixedly connected to a piston head 209.

[0037] The inner side of the piston cylinder 303 is a connecting structure, and the two piston heads 209 slide together on the inner side of the piston cylinder 303. When the two piston heads 209 are close to each other, the pressure inside the piston cylinder 303 increases, thereby pushing the liquid to flow outward. When the two piston heads 209 are far away from each other, the pressure inside the piston cylinder 303 decreases, thereby allowing the liquid to move to the inner side of the piston cylinder 303. The structural setting of the two piston heads 209 moving symmetrically on the inner side of the piston cylinder 303 can make the device have a stronger suction force, and cooperate with the pedal 201 to achieve a suction force that cannot be achieved by a general suction structure, and achieve a good suction effect without power, which can meet most suction needs in actual operations.

[0038] According to a further optimization scheme, a first through hole is opened in the middle of the movable seat 205, and a second slide rod 212 is slidably connected in the two first through holes. A second slide hole 306 is opened in the middle of the piston sleeve 301, and the second slide rod 212 is slidably connected to the second slide hole 306.

[0039] The cooperation between the second slide bar 212 and the second slide hole 306 ensures that the two movable seats 205 can only reciprocate in one direction, thereby ensuring the stability of the force of the device and reducing the mechanical deformation caused by stepping on.

[0040] A further optimized solution is provided, in which the piston reset structure includes a reset seat 203, one side of the reset seat 203 is rotatably connected to the connecting rotating seat 204 through a reset seat ear plate, a second through hole is provided in the middle of the reset seat 203, and the first slide rod 206 is slidably connected in the two second through holes, a first slide hole 307 is provided in the piston sleeve base 305, and the first slide rod 206 is slidably connected to the first slide hole 307, and one end of the reset spring 207 is fixedly connected to the side of the reset seat 203 close to the piston sleeve base 305, the reset spring 207 is sleeved on the peripheral side of the first slide rod 206, and the other end of the reset spring 207 abuts against the piston sleeve base 305.

[0041] Two return springs 207 are arranged on both sides of the piston sleeve base 305, which can push the return seat 203 to return, and the setting of the first slide rod 206 ensures that the return seat 203 can reciprocate in one direction, and also reduces the mechanical deformation caused by stepping on.

[0042] Further optimizing the scheme, the delivery pipeline includes a first pipe group and a second pipe group, the first pipe group includes a three-way joint 104, the three-way joint 104 is fixedly connected with the anti-backflow three-way structure 105, the other two ends of the three-way joint 104 are respectively fixedly connected with one end of two first pipes 102 through a right-angle joint 103, and the other end of the first pipe 102 is fixedly connected with the bottom end of the piston cylinder 303 through the piston water inlet head 302. Among them, the number of first pipes 102 can be changed according to the number of piston cylinders 303.

[0043] To further optimize the solution, the second pipe group includes a second pipeline 108, one end of the second pipeline 108 is fixedly connected to the anti-backflow three-way structure 105 through an anti-backflow valve 106, and the other ends of the two second pipelines 108 are fixedly connected to each other via a three-way water inlet head 109.

[0044] According to a further optimized solution, baffles 304 are fixedly connected to both ends of the piston cylinder 303 , the piston head 209 is slidably connected between the two baffles 304 , and the connection port between the piston water inlet head 302 and the piston cylinder 303 is located between the two piston heads 209 .

[0045] The piston head 209 is preferably made of rubber. The setting of the baffle 304 ensures that the piston head 209 will not separate from the piston cylinder 303. At the same time, it can also protect the inside of the piston cylinder 303, reduce pollution, and slow down the aging of the rubber on the piston head 209.

[0046] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0047] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
