Description

Technical Field

[0001] The utility model relates to the technical field of air pumps, in particular to an air pump with an air pumping function and a vacuum suction cup device. Background Art

[0002] Nowadays, when renovating houses, workers need to use vacuum suction cups to carry tiles and assist workers in laying tiles. For example, vacuum suction cups with announcement numbers CN215402534U, CN217676270U, ​​CN218260767U and CN220316535U mainly include a vacuum suction cup body and an elastic piston. The vacuum suction cup body has a piston hole, and the vacuum suction cup is evacuated by an elastic piston (including a piston and an elastic member for resetting the piston) installed on the piston hole. The working principle is that the vacuum suction cup body has a suction cup part, and the space formed by the suction cup part is connected to the piston hole, and a one-way valve structure is usually provided between the space formed by the suction cup part and the piston hole, so that the elastic piston can be pressed to make the piston reciprocate to evacuate air, that is, the air in the space formed by the suction cup part is discharged, so that the suction cup part and the tile surface form a negative pressure, and the suction cup part and the tile are adsorbed.

[0003] The conventional vacuum suction cup uses an elastic piston (including the piston and an elastic member for resetting the piston) installed on the piston hole to evacuate air, and the operator needs to press frequently during operation, which is laborious to use. Utility Model Content

[0004] In view of the above problems, the utility model provides an air pump with air extraction function and a vacuum suction cup device.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A vacuum pump with a vacuum pumping function, used for being installed on a vacuum suction cup body, comprising a housing, a detection box, a vacuum pump, a battery assembly, a circuit board, a control button and a sealing ring;

[0007] The detection box is fixed at one end of the housing, the vacuum pump, the battery assembly and the circuit board are installed in the housing or in the space formed by the detection box and the housing, and the vacuum pump, the battery assembly and the control button are all electrically connected to the circuit board;

[0008] The end of the detection box has a first hole, and the vacuum pump extracts air through the first hole;

[0009] The sealing ring is installed on the outer side wall of the detection box or the shell.

[0010] The present application is used to be installed on the vacuum suction cup body, replacing the elastic piston of the traditional manual vacuum suction cup. The present application can transform an ordinary vacuum suction cup into an electric vacuum suction cup. The outer wall of the detection box or shell of the present application has a sealing ring, through which the vacuum cylinder of the present application and the vacuum suction cup can be reliably sealed, so that the vacuum pump can reliably evacuate air. When the present application is working, the vacuum pump works and evacuates air through the first hole, 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.

[0011] It should be noted that, the “detection box is fixed to one end of the outer shell” mentioned in the present application also includes a structure in which the detection box and the outer shell are integrated, that is, the detection box is a part of the outer shell.

[0012] In one embodiment of the present invention, the outer wall of the detection box or the outer wall of the shell has an annular installation groove, and the sealing ring is installed on the installation groove. This arrangement facilitates the assembly of the sealing ring.

[0013] In one embodiment of the present invention, the sealing ring is installed on the detection box, the end of the detection box away from the shell is the working end, and the sealing ring has a gradient section, and the farther away from the working end in the gradient section, the larger the outer diameter of the sealing ring.

[0014] The sealing ring is installed on the detection box. Compared with installing it on the outer shell, there is no need to design a special sealing structure between the detection box and the outer shell; the setting of the gradient section enables the sealing ring to effectively ensure the sealing effect when it is installed on the piston hole of the hollow suction cup.

[0015] In one embodiment of the present invention, an air pressure sensor is further included, and the air pressure sensor is electrically connected to the circuit board;

[0016] The end of the detection box has a second hole, and the end of the air pressure sensor detects air pressure through the second hole.

[0017] The air pressure can be detected through the second hole and the air pressure sensor, and can be set so that when the air pressure is lower than the set pressure, the circuit board controls the vacuum pump to work and supplement the air. For example, when the negative pressure between the vacuum suction cup and the tile is detected to be lower than 0.4 bar, the vacuum pump is started.

[0018] In actual use, in order to improve the sealing performance, sealant can be applied to the connection between the air pressure sensor and the second hole, or a sealing gasket can be placed on the end of the air pressure sensor (the detection box has a receiving groove that matches the sealing gasket).

[0019] In one embodiment of the present invention, a two-way valve is further included, one end of the two-way valve is connected to the first hole, and the other end of the two-way valve is connected to the vacuum pump.

[0020] In actual use, in order to improve the sealing performance, sealant can be applied to the connection between the two-way valve and the first hole, or a sealing gasket can be placed on the end of the two-way valve that matches the first hole (the detection box has a accommodating groove that matches the sealing gasket).

[0021] In actual application, the two-way valve can be a one-way valve or a solenoid valve.

[0022] In one embodiment of the present invention, one end of the two-way valve is connected to the vacuum pump through a pipeline.

[0023] In one embodiment of the present invention, it further includes a battery installation box and a connecting plate;

[0024] The battery installation box is arranged in the housing and is used for installing the battery assembly;

[0025] The connecting plate is connected to one end of the vacuum pump, and the connecting plate is fixed to the detection box via connecting screws.

[0026] In one embodiment of the present invention, one of the detection box and the housing has an L-shaped slot, and the other has a mounting block, and the detection box and the housing are rotatably engaged through the matching slot and mounting block.

[0027] During assembly, first place the mounting block at the notch of the L-shaped slot, move it a certain distance, and then rotate it to complete the installation operation. This structure is more convenient for assembly and disassembly.

[0028] In one embodiment of the present invention, the control button is located at one end of the housing away from the detection box; a digital display board is also included, and the digital display board is electrically connected to the circuit board.

[0029] The digital display board can display relevant parameter information (such as air pressure value, battery component power, etc.).

[0030] In one embodiment of the present invention, the end of the housing has a through hole for the control button to pass through.

[0031] In one embodiment of the present invention, an indicator light is disposed on the circuit board. The indicator light has multiple colors for indicating different states.

[0032] In actual use, the circuit of the circuit board can be set as needed. For example, by long pressing the control button for 2 seconds, the vacuum pump works and the red light is on. When the negative pressure reaches 0.60 bar, the red light goes out and the green light comes on. The vacuum pump runs for 3 seconds and then stops working.

[0033] The present application can realize multiple operation forms, such as one working mode: install the vacuum pump on the piston hole of the vacuum suction cup, then contact the vacuum suction cup with the tile, and start and stop the vacuum pump by manually controlling the control button. For example, another working mode: install the vacuum pump on the piston hole of the vacuum suction cup, then contact the vacuum suction cup with the tile, and then press the control button to make the vacuum pump work (specifically set 2, the vacuum pump 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 runs for 3 seconds and 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 carry 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 to below 40 kPa, the vacuum pump is started to evacuate again. When the negative pressure increases to 60 kPa, the vacuum pump stops working.

[0034] The present application also discloses a vacuum suction cup device, including a vacuum suction cup body, the vacuum suction cup body having a piston hole, and also including the above-mentioned vacuum pump with a vacuum pumping function, the vacuum pump is used to be installed on the piston hole of the vacuum suction cup body, and the sealing ring is used to seal with the piston hole.

[0036] The vacuum pump of the present application can be used for automatic vacuuming by a vacuum pump, or it can be used for vacuuming by reciprocatingly moving the vacuum pump on the piston hole when power is out, so that the space formed by the suction cup and the surface of the tile form a negative pressure, and the suction cup and the tile are adsorbed.

[0037] In one embodiment of the present invention, the housing has an elastic limiting structure, and the elastic limiting structure is used to assist the vacuum pump in being installed and limited on the vacuum cup body;

[0038] The elastic limiting structure includes a clamping part and an elastic member arranged on the side of the shell away from the detection box, the clamping frame part is rotatably installed on the shell, and the elastic member is a torsion spring used to make the clamping frame part have a rotation tendency to rotate toward the side wall of the shell to clamp; or, the elastic limiting structure includes an elastic rope and a hook, one end of the elastic rope is connected to the side of the shell away from the detection box, and the other end is connected to the hook, and the hook is used to clamp on the vacuum suction cup body.

[0039] In the present application, the side of the housing away from the detection box is not limited to the end portion, and the area close to the end portion also belongs to the side of the housing away from the detection box.

[0040] The beneficial effects of the utility model are as follows: the application is used to be installed on a vacuum suction cup, replacing the elastic piston of a traditional manual vacuum suction cup, and the application can transform an ordinary vacuum suction cup into an electric vacuum suction cup. The outer wall of the detection box or the shell of the application is provided with a sealing ring, through which the vacuum cylinder of the application and the vacuum suction cup can be reliably sealed, so that the vacuum pump can reliably evacuate air.

[0055] The utility model is described in detail below in conjunction with the accompanying drawings.

[0056] Example 1

[0057] like Figures 1 to 8 As shown, a vacuum pump with a vacuum function is used to be installed on a vacuum suction cup body. The vacuum pump with a vacuum function includes a housing 1, a detection box 2, a vacuum pump 31, a battery assembly 32, a circuit board 33, a control button 34 and a sealing ring 4;

[0058] The detection box 2 is fixed to one end of the housing 1, and 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 vacuum pump 31, the battery assembly 32 and the control button 34 are all electrically connected to the circuit board 33;

[0059] The end of the detection box 2 has a first hole 23, and the vacuum pump 31 extracts air through the first hole 23;

[0060] The sealing ring 4 is installed on the outer side wall of the detection box 2 or the housing 1 .

[0061] The present application is used to be installed on the vacuum suction cup body, replacing the elastic piston of the traditional manual vacuum suction cup. The present application can transform an ordinary vacuum suction cup into an electric vacuum suction cup. The present application has a sealing ring 4 on the outer wall of the detection box 2 or the outer shell 1, through which the vacuum cylinder of the present application and the vacuum suction cup body can be reliably sealed, so that the vacuum pump 31 can reliably evacuate air. When the present application is working, the vacuum pump 31 works and evacuates air through the first hole 23, so that the space in contact between the vacuum suction cup body and the ceramic tile is in a negative pressure state, and the ceramic tile is reliably adsorbed.

The farther away from the working end 2a in the gradient section 41, the larger the outer diameter of the sealing ring 4.

[0064] 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.

[0067] The air pressure can be detected through the second hole 22 and the air pressure sensor 51. When the air pressure is lower than the set pressure, the circuit board 33 controls the vacuum pump 31 to work and perform additional air extraction. For example, when the negative pressure between the vacuum suction cup body and the tile is detected to be lower than 0.4 bar, the vacuum pump 31 is started.

[0068] In actual use, in order to improve the sealing performance, sealant can be applied to the connection between the air pressure sensor 51 and the second hole 22, or a sealing gasket 6 can be installed on the end of the air pressure sensor 51 (the detection box 2 has a receiving groove 25 that matches the sealing gasket 6).

[0069] like Figure 3 and 6 As shown, in this embodiment, a two-way valve 52 is further included, one end of the two-way valve 52 is connected to the first hole 23 , and the other end of the two-way valve 52 is connected to the vacuum pump 31 .

[0071] In actual use, the two-way valve 52 can be a one-way valve or a solenoid valve.

[0072] like Figure 3 and 6 As shown, in this embodiment, one end of the two-way valve 52 is connected to the vacuum pump 31 through a pipeline 521 .

[0073] like Figure 3 and 4 As shown, in this embodiment, it also includes a battery installation box 38 and a connecting plate 35;

[0074] The battery installation box 38 is disposed in the housing 1 and is used to install the battery assembly 32;

[0075] 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 .

[0076] 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.

[0077] 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.

[0078] like Figure 1 and4 As shown, in this embodiment, the control button 34 is located at one end of the housing 1 away from the detection box 2 ; a digital display board 37 is also included, and the digital display board 37 is electrically connected to the circuit board 33 .

[0079] The digital display board 37 can display relevant parameter information (such as air pressure value, battery level of the battery assembly 32, etc.).

[0080] like Figure 4 As shown, in this embodiment, the end of the housing has a through hole 12 for the control button 34 to pass through.

[0081] 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.

[0082] 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.

[0083] 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 body, and then the vacuum suction cup body 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 body, then contact the vacuum suction cup body 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 body and the tile is extracted, and the vacuum suction cup body 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 body and the tile. When the sensor detects that the negative pressure on the contact surface between the vacuum suction cup body 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.

The vacuum pump of the present application can be automatically evacuated by the vacuum pump 31, or it can be evacuated by reciprocating the vacuum pump on the piston hole 301 when there is no power, so that the space formed by the suction cup part 302 and the surface of the tile form a negative pressure, and the suction cup part 302 is adsorbed on the tile.

[0086] Example 2

[0087] like Fig. 9 As shown, the difference between this embodiment and embodiment 1 is that in this embodiment, the outer shell 1 of the vacuum pump has an elastic limiting structure, and the elastic limiting structure is used to assist the vacuum pump in being installed and limited on the vacuum suction cup body 300.

[0088] In this embodiment, the elastic limiting structure includes an elastic rope 401 and a hook 402. One end of the elastic rope 401 is connected to the side of the housing 1 away from the detection box 2, and the other end is connected to the hook 402. The hook 402 is used to clamp on the vacuum suction cup body 300. In actual use, the elastic limiting structure can also include a clamping part and an elastic member arranged on the side of the housing 1 away from the detection box 2.
