Description

Technical Field

[0001] The utility model relates to the technical field of air pumps, in particular to an air pump with an automatic air pumping function. Background Art

[0002] Vacuum pumps are used in many products, such as clothing storage, vacuum suction cups and other products, and vacuum suction cups are used more frequently. In today's house decoration, workers need to use vacuum suction cups to move tiles and assist workers in laying tiles. For example, vacuum suction cups with announcement numbers CN215402534U, CN217676270U, ​​CN218260767U and CN220316535U mainly include vacuum suction cup bodies and elastic pistons. The vacuum suction cup bodies have piston holes, and the vacuum suction cups are evacuated through elastic pistons (including pistons and elastic parts for resetting the pistons) installed on the piston holes. The working principle is that the vacuum suction cup body has a suction cup part, the space formed by the suction cup part is connected to the piston hole, and a one-way valve structure is usually arranged between the space formed by the suction cup part and the piston hole, so that air can be pumped out by pressing the elastic piston to make the piston move back and forth, that is, the air in the space formed by the suction cup part is discharged, so that negative pressure is formed between the suction cup part and the surface of the tile, and the suction cup part and the tile are adsorbed.

[0003] The vacuum cup is evacuated by an elastic piston (including a piston and an elastic member for resetting the piston) installed on the piston hole. When working, the elastic piston is pressed to make the piston move back and forth to evacuate air, which requires the operator to press frequently and is laborious to use. In addition, after the air on the contact surface between the vacuum cup and the tile is evacuated, air sometimes enters between the vacuum cup and the tile during transportation, making the adsorption between the vacuum cup and the tile unreliable, causing the tile to fall off the vacuum cup during transportation.

[0048] The utility model is described in detail below in conjunction with the accompanying drawings.

[0049] Example 1

[0050] like Figures 1 to 4 As shown, a vacuum pump with automatic vacuum function includes a housing 1, a detection box 2, a two-way valve 52, an air pressure sensor 51, a vacuum pump 31, a battery assembly 32, a circuit board 33, a control button 34 and a sealing ring 4;

[0051] The detection box 2 is fixed to one end of the housing 1, and the two-way valve 52 and the air pressure sensor 51 are installed in the detection box 2;

[0052] The vacuum pump 31, the battery assembly 32 and the circuit board 33 are installed in the housing 1 or in the space formed by the detection box 2 and the housing 1. The air pressure sensor 51, the vacuum pump 31, the battery assembly 32 and the control button 34 are all electrically connected to the circuit board 33.

[0053] The end of the detection box 2 has a first hole 23 and a second hole 22. One end of the two-way valve 52 is connected to the first hole 23, and the other end is connected to the vacuum pump 31. The vacuum pump 31 extracts air through the first hole 23. The end of the air pressure sensor 51 penetrates the second hole 22, and the air pressure sensor 51 detects air pressure through the second hole 22.

[0054] The sealing ring 4 is installed on the outer side wall of the detection box 2 or the housing 1 .

[0055] like Figure 3 and 4 As shown, in this embodiment, a sealing gasket 6 is also included;

[0056] The detection box 2 has two receiving grooves 25, the first hole 23 and the second hole 22 are respectively located on the bottom walls of the two receiving grooves 25, and a sealing gasket 6 is installed in the receiving groove 25;

[0057] One end of the two-way valve 52 passes through the corresponding sealing gasket 6 and is connected to the first hole 23;

[0058] One end of the air pressure sensor 51 passes through the corresponding sealing gasket 6 and is connected to the second hole 22 .

[0059] The sealing gasket 6 can prevent air leakage and ensure the normal and efficient implementation of the air extraction work.

[0060] like Figure 3 and 4 As shown, in this embodiment, the outer wall of the detection box 2 or the outer wall of the housing 1 has an annular mounting groove 21, and the sealing ring 4 is mounted on the mounting groove 21. This arrangement facilitates the assembly of the sealing ring 4.

[0061] like Figure 2As shown, in this embodiment, the sealing ring 4 is installed on the detection box 2, the end of the detection box 2 away from the shell 1 is the working end 2a, and the sealing ring 4 has a gradient section 41. The farther away from the working end 2a in the gradient section 41, the larger the outer diameter of the sealing ring 4.

[0062] The sealing ring 4 is installed on the detection box 2. Compared with being installed on the outer shell 1, there is no need to design a special sealing structure between the detection box 2 and the outer shell 1; the setting of the gradient section 41 enables the sealing ring 4 to effectively ensure the sealing effect when it is installed on the piston hole of the hollow suction cup.

[0063] like Figure 3 As shown, in this embodiment, one end of the two-way valve 52 is connected to the vacuum pump 31 through a pipeline 521 .

[0064] like Figure 3 and 4 As shown, in this embodiment, it also includes a battery installation box 38 and a connecting plate 35;

[0065] The battery installation box 38 is disposed in the housing 1 and is used to install the battery assembly 32;

[0066] The connecting plate 35 is connected to one end of the vacuum pump 31 , and the connecting plate 35 is fixed to the detection box 2 via connecting screws 36 .

[0067] like Figure 3 As shown, in this embodiment, one of the detection box 2 and the housing 1 has an L-shaped slot 24, and the other has a mounting block 11. The detection box 2 and the housing 1 are rotatably engaged through the matching slot 24 and the mounting block 11.

[0068] During assembly, the installation block 11 is first placed at the notch of the L-shaped slot 24, moved for a certain distance, and then rotated to complete the installation operation. This structure is more convenient for assembly and disassembly.

[0069] like Figure 1 and 4 As shown, in this embodiment, a digital display board 37 is also included;

[0070] The circuit board 33 and the control button 34 are located at one end of the housing 1 away from the detection box 2;

[0071] The digital display board 37 is electrically connected to the circuit board 33 .

[0072] like Figure 4 As shown, in this embodiment, the end of the housing 1 has a through hole 12 for the control button 34 to pass through.

[0073] In this embodiment, an indicator light (omitted and not shown in the figure) is provided on the circuit board 33, and the indicator light has multiple colors for indicating different states.

[0074] In actual use, the circuit of the circuit board 33 can be set as needed. For example, by pressing and holding the control button 34 for 2 seconds, the vacuum pump 31 works and the red light comes on. When the negative pressure reaches 0.60 bar, the red light goes out and the green light comes on. The vacuum pump 31 runs for 3 seconds and then stops working.

[0075] The vacuum pump of the present application can be used on vacuum suction cups, and can also be used in other fields, such as clothing storage, etc. When used on vacuum suction cups, the present application can replace the elastic piston of traditional manual vacuum suction cups, and can transform ordinary vacuum suction cups into electric vacuum suction cups. When the vacuum pump 31 is working, the vacuum pump 31 evacuates air through the first hole 23, so that the space in contact between the vacuum suction cup and the tile is in a negative pressure state, and the tile is reliably adsorbed; the present application can detect the air pressure through the second hole 22 and the air pressure sensor 51, and can be set to control the circuit board 33 to control the vacuum pump 31 to work and supplement the air when it is lower than the set air pressure. For example, when it is detected that the negative pressure between the vacuum suction cup and the tile is lower than 0.4 bar, the vacuum pump 31 is started, that is, the present application can solve the problem that the existing vacuum suction cups are not reliably adsorbed and cannot automatically evacuate air during transportation.

[0076] The outer side wall of the detection box 2 or the housing 1 of the present application is provided with a sealing ring 4, through which the vacuum cylinder of the present application and the vacuum suction cup can be reliably sealed, so that the vacuum pump 31 can reliably evacuate air.

[0077] This embodiment can realize multiple operation modes, such as a working mode: the vacuum cylinder is installed on the piston hole of the vacuum suction cup, and then the vacuum suction cup is contacted with the tile, and the vacuum pump 31 is started and stopped by manually controlling the control button 34. For example, another working method is: install the vacuum cylinder on the piston hole of the vacuum suction cup, then contact the vacuum suction cup with the tile, and then press the control button 34 to make the vacuum pump 31 work (specifically set 2, the vacuum pump 31 can be made to work after pressing for 2 seconds), the indicator light is red, and when the negative pressure reaches 60 kPa, the red light goes out and the green light is on. At this time, the vacuum pump 31 runs for 3 seconds and the vacuum pump 31 stops working. At this time, the air on the contact surface between the vacuum suction cup and the tile is extracted, and the vacuum suction cup and the tile are firmly adsorbed, so that the staff can move the tile. During the transportation process, gas enters the contact surface between the vacuum suction cup and the tile. When the sensor detects that the negative pressure on the contact surface between the vacuum suction cup and the tile drops below 40 kPa, the vacuum pump 31 is started to evacuate again. When the negative pressure increases to 60 kPa, the vacuum pump 31 stops working.

[0078] In actual use, the vacuum pump of this embodiment can reciprocate relative to the piston hole. When the vacuum pump is moved back and forth, the vacuum pump can realize the manual vacuuming function, that is, the vacuum pump can also realize the vacuuming function when the vacuum pump has no power. This application has strong adaptability.

[0079] Example 2

[0080] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that it further includes a vent pipe 100 and a vent valve 200 , one end of the vent pipe 100 passes through the end of the detection box 2 , and the other end of the vent pipe 100 is installed with the vent valve 200 .

[0081] In actual use, the air release valve 200 may be a manual valve, and in this case, the control portion of the air release valve 200 passes through the housing 1 .

[0082] In actual use, the air release valve 200 can also be an electrically controlled valve. The air release valve 200 is electrically connected to the circuit board 33. There are multiple control buttons 34, and one of the control buttons 34 is used to control the air release valve 200 to open.

[0083] The deflation valve 200 is provided with the deflation pipe 100 and the deflation valve 200 to realize the deflation operation, so that the equipment matched with the vacuum pump is no longer in a negative pressure state. When applied to a vacuum suction cup, the deflation pipe 100 and the deflation valve 200 are particularly suitable for a vacuum suction cup that is not provided with a special deflation structure.

[0084] In other embodiments, one end of the vent pipe 100 may also be connected to the first hole 23. In actual use, one form of the vent pipe 100 being connected to the first hole 23 is that the end of the two-way valve 52 connected to the first hole 23 and one end of the first hole 23 is a connecting section, and one end of the vent pipe 100 is connected to the connecting section.

[0085] The above description is only a preferred embodiment of the utility model, and does not limit the patent protection scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the utility model.
