Technical Field

[0001] The present application relates to the technical field of membrane pumps, and in particular to an inflatable and deflable membrane pump. Background Art

[0002] In our daily life, there are many daily necessities that need to be inflated before they can be used. However, the inflatable devices used in our daily life often use two separate air nozzles to perform air extraction or inflation respectively, and cannot use a single air nozzle to both inflate and switch to air extraction.

[0003] In view of the above-mentioned related technologies, the inventors recognize that the existing inflation devices on the market have the defect that they cannot be used for both inflation and exhaust through the same air nozzle.

[0009] The air pressure detection device is arranged on one side of the base and is used to detect the air pressure when the inflatable and deflable membrane pump is working.

[0010] By adopting the above technical solution, a diaphragm pump is arranged in the movement body. When the diaphragm pump is working, it ejects air outward from the air outlet and sucks air into the movement body at the air inlet. The inflatable and deflable diaphragm pump is adjusted to inflate or evacuate air through the air pressure conversion component, and the air pressure detection device detects the air pressure in real time during operation.

[0011] Preferably, the movement body further includes:

[0012] An air groove is arranged on one end of the movement body connected to the air pressure conversion component, the air outlet is arranged in the air groove near the edge, and the air inlet and the air outlet are arranged at intervals;

[0013] A sealing sheet is arranged in the air groove, and air holes are arranged at intervals on the sealing sheet, and the air holes are arranged corresponding to the air outlet and the air inlet.

[0014] By adopting the above technical solution, after the air pressure conversion component is assembled with the movement body, the movement body is connected to the air pressure conversion component through the air groove, and the sealing sheet improves the sealing of the connection, prevents air leakage, and improves the working efficiency of air extraction and air inhalation.

[0015] Preferably, the air pressure conversion assembly further comprises:

[0016] An air inlet groove is arranged on the second surface of the base, the air inlet groove is arranged corresponding to the air inlet hole, and the air inlet groove is connected to the air nozzle;

[0017] An air outlet groove is arranged on the second surface of the base, the air outlet groove is arranged corresponding to the air outlet hole, the air outlet groove is located on one side of the air inlet groove, and the air outlet groove is connected to the air nozzle.

[0018] By adopting the above technical solution, the air inlet groove is connected to the air inlet hole, the air outlet groove is connected to the air outlet hole, and finally the product that needs to be pumped or inflated is connected through the air nozzle to inflate or pump air into the product.

[0019] Preferably, the air pressure conversion assembly further comprises a sealing line, and the sealing line is arranged around the outer sides of the air inlet groove and the air outlet groove.

[0020] By adopting the above technical solution and setting the sealing line, the sealing performance of the connection between the air inlet groove and the air inlet hole and the sealing performance of the connection between the air outlet groove and the air outlet hole are further improved to prevent air leakage, thereby improving the efficiency of the inflatable and deflable membrane pump during inflation and deflating operations.

[0021] Preferably, the toggle switch comprises:

[0022] An air pressure conversion shaft is slidably disposed in the through hole, a circular sealing disc is disposed on the air pressure conversion shaft at intervals, an embedding groove is disposed around the sealing disc, and a sealing ring is further disposed in the embedding groove;

[0023] A connecting part is arranged at both ends of the air pressure conversion shaft, the connecting part is a semi-cylindrical structure, and a first connecting column is arranged on one side of the plane of the connecting part;

[0024] The U-shaped slide plate is sleeved and assembled on the first connecting columns which are arranged at intervals.

[0025] By adopting the above technical scheme, the air pressure conversion shaft is slidably arranged in the through hole, wherein the radial dimension of the sealing circular plate is larger than the radial dimension of the air pressure conversion shaft, so that the air hole is isolated into connecting parts on both sides and an isolating part in the middle, and the air pressure conversion shaft slides to connect the connecting part with the air inlet hole. When the diaphragm pump in the movement body works, air is sucked in from the through hole and enters the movement body from the air inlet hole. The operation of the diaphragm pump drives the air to move from the air outlet to the isolating part. At this time, the isolating part is connected with the air nozzle, and the air is ejected outward from the air nozzle, so that the inflatable and deflable diaphragm pump can perform inflation work.

[0026] When the air pressure conversion shaft is slid to connect the air outlet with the connecting part, the air inlet is connected with the isolating part and the air nozzle. When the membrane pump in the movement body works, air is sucked into the movement body through the air inlet. Since the air inlet is connected with the air nozzle, air enters from the air nozzle through the isolating part and flows into the movement body. The air is driven by the membrane pump to flow out from the air outlet. Since the air outlet is connected with the connecting part, the connecting part is connected with the outside of the inflatable and deflable membrane pump, so that the air is directly discharged to the outside of the inflatable and deflable membrane pump, thereby performing the air extraction work.

[0027] The U-shaped slide plate is provided to facilitate the operator to slide the air pressure conversion shaft, thereby improving the convenience and efficiency of the conversion of air extraction or inflation.

[0029] The second connecting column is arranged on the connecting platform at intervals, and the second connecting column is provided with a first threaded hole, and a fixing screw is rotatably arranged in the first threaded hole. The U-shaped slide plate is also provided with sliding grooves passing through the U-shaped slide plate at intervals, and the fixing screws are also arranged in the sliding grooves.

[0030] By adopting the above technical solution and setting the second connecting column, the U-shaped slide plate is slidably set between the second connecting column and the fixing screw through the sliding groove, thereby improving the stability of sliding the air pressure conversion shaft through the U-shaped slide plate.

[0032] The sensor sleeve, the connecting platform is provided with an air pressure hole on one side away from the second connecting column, the air pressure hole is connected to the air nozzle, and the sensor sleeve is inserted and arranged in the air pressure hole;

[0033] An air pressure detection plate, wherein a sensor is disposed on the first surface of the air pressure detection plate, and the sensor is inserted into the sensor sleeve.

[0034] By adopting the above technical solution, since the air pressure hole is connected to the air nozzle, when the inflatable and deflable membrane pump is performing vacuuming or inflation, air will flow into the air pressure hole, and the sensor determines whether the inflatable and deflable membrane pump is working normally by detecting the air pressure, thereby improving the efficiency of maintenance and inspection of the inflatable and deflable membrane pump.

[0035] Preferably, the air pressure detection device further includes:

[0036] A reinforcing screw is arranged on the second surface of the air pressure detection plate and penetrates the air pressure detection plate. A connecting wall extending out of the connecting platform is arranged on the side away from the second connecting column. A second threaded hole is arranged on the connecting wall. The reinforcing screw is also assembled in the second threaded hole.

[0037] The protrusion is arranged on the connecting wall away from the second connecting column. The air pressure detection plate is also provided with grooves at intervals. The grooves are arranged corresponding to the protrusions. When the air pressure detection plate is assembled on the connecting wall, the protrusions are located in the grooves.

[0038] By adopting the above technical solution, by setting the reinforcing screws, the stability of the assembly of the air pressure detection plate in the direction perpendicular to the air pressure detection plate is improved, and by setting the protrusions and the grooves, the stability of the assembly in the direction parallel to the plane where the air pressure detection plate is located is improved.

[0039] Preferably, the inflatable and deflable membrane pump further comprises:

[0040] A docking platform is arranged on the second surface of the base, and the docking platforms are arranged at intervals on four sides of the base;

[0041] The docking grooves are arranged on four sides of the movement body close to the base, and the docking grooves are arranged corresponding to the docking platform.

[0042] By adopting the above technical solution and providing the docking platform and the docking groove, the accuracy of the assembly connection between the air pressure conversion component and the movement body is improved.

[0043] Preferably, the sealing sheet comprises a straight plate portion provided with the air holes and a convex plate portion provided on a side away from the air holes, and the shape of the air groove is the same as that of the sealing sheet.

[0044] By adopting the above technical solution and performing fool-proofing treatment on the sealing sheet, the sealing sheet can be prevented from being assembled in reverse, thereby improving the accuracy of the overall assembly.

[0045] The beneficial effects of the present application are as follows: the inflatable and deflable diaphragm pump provided by the present application can perform inflation work and can also switch to exhaust work through a single air nozzle through the setting of an air pressure conversion component, thereby improving the versatility of the inflatable and deflable diaphragm pump, and the overall structure is compact and small in size, which reduces the space occupied during use and reduces production costs.

[0059] A diaphragm pump is provided in the movement body 100.

The inflatable and deflable diaphragm pump is adjusted by the air pressure conversion component to perform inflation or deflating work, and the air pressure detection device detects the air pressure in real time during operation.

[0060] See also Figure 2 , Figure 3 As shown, the movement body 100 further includes an air groove 101 and a sealing sheet 110 .

The air holes 113 are arranged at intervals on the sealing sheet 110, and the air holes 113 are arranged corresponding to the air outlet 103 and the air inlet 102.

[0062] After the air pressure conversion assembly is assembled with the movement body 100, the movement body 100 is connected to the air pressure conversion assembly through the air groove 101, and the sealing sheet 110 improves the sealing of the connection, prevents air leakage, and improves the working efficiency of air extraction and air inhalation.

[0063] See also Figure 2 , Figure 4 As shown, the air pressure conversion assembly further includes an air inlet groove 124 and an air outlet groove 125 .

[0064] The air inlet groove 124 is arranged on the second surface of the base 120, and the air inlet groove 124 is arranged corresponding to the air inlet hole 102. The air inlet groove 124 is connected to the air nozzle 123. The air outlet groove 125 is arranged on the second surface of the base 120, and the air outlet groove 125 is arranged corresponding to the air outlet hole 103. The air outlet groove 125 is located on one side of the air inlet groove 124, and the air outlet groove 125 is connected to the air nozzle 123.

[0065] The air inlet groove 124 is connected to the air inlet hole 102, the air outlet groove 125 is connected to the air outlet hole 103, and finally the air nozzle 123 is connected to the product that needs to be evacuated or inflated to inflate or evacuate the product.

[0066] See also Figure 4 As shown, the air pressure conversion assembly also includes a sealing line 126, which is arranged around the outer sides of the air inlet groove 124 and the air outlet groove 125. Through the arrangement of the sealing line 126, the sealing performance of the connection between the air inlet groove 124 and the air inlet hole 102 and the sealing performance of the connection between the air outlet groove 125 and the air outlet hole 103 are further improved to prevent air leakage, thereby improving the efficiency of the inflatable and deflable membrane pump during inflation and exhaust operations.

[0067] See also Figure 2 , Figure 4 As shown, the toggle switch includes an air pressure conversion shaft 130 , a sealing circular plate 131 , a sealing ring 133 and a U-shaped slide plate 140 .

[0068] The air pressure conversion shaft 130 is slidably arranged in the through hole 122. Circular sealing discs 131 are arranged at intervals on the air pressure conversion shaft 130. An embedding groove 132 is arranged around the sealing disc 131. A sealing ring 133 is further arranged in the embedding groove 132. A connecting part 134 is arranged at both ends of the air pressure conversion shaft 130. The connecting part 134 is a semi-cylindrical structure. A first connecting column 135 is arranged on one side of the plane of the connecting part 134. The U-shaped slide plate 140 is sleeved and assembled on the first connecting column 135 arranged at intervals.

[0069] See also Figure 5 As shown, the air pressure conversion shaft 130 is slidably arranged in the through hole 122, wherein the radial dimension of the sealing circular plate 131 is larger than the radial dimension of the air pressure conversion shaft 130, so that the air hole is isolated into a connecting portion 180 on both sides and an isolating portion 181 located in the middle. The air pressure conversion shaft 130 slides to connect the connecting portion 180 with the air inlet 102. When the diaphragm pump in the movement body 100 is working, air is sucked in from the through hole 122 and enters the movement body 100 from the air inlet 102. The operation of the diaphragm pump drives the air to move from the air outlet 103 to the isolating portion 181. At this time, the isolating portion 181 is connected to the air nozzle 123, and the air is ejected outward from the air nozzle 123, so that the inflatable and deflable diaphragm pump can perform inflation work.

[0070] See also Figure 6As shown, when the sliding air pressure conversion shaft 130 connects the air outlet 103 with the connecting part 180, the air inlet 102 is connected with the insulating part 181 and the air nozzle 123. When the membrane pump in the movement body 100 is working, air is sucked into the movement body 100 through the air inlet 102. Since the air inlet 102 is connected with the air nozzle 123, air enters from the air nozzle 123 through the insulating part 181 and flows into the movement body 100. The air is driven by the membrane pump to flow out from the air outlet 103. Since the air outlet 103 is connected with the connecting part 180, the connecting part 180 is connected with the outside of the inflatable and deflable membrane pump, so that the air is directly discharged to the outside of the inflatable and deflable membrane pump, thereby performing the air extraction work.

[0071] The U-shaped slide plate 140 is provided to facilitate the operator to slide the air pressure conversion shaft 130 , thereby improving the convenience and efficiency of the conversion of air extraction or inflation.

[0072] See also Figure 2 As shown, the inflatable and deflable diaphragm pump also includes a second connecting column 150 and a fixing screw 152. The second connecting column 150 is arranged at intervals on the connecting platform 121. The second connecting column 150 is provided with a first threaded hole 151. The fixing screw 152 is rotatably arranged in the first threaded hole 151. The U-shaped slide plate 140 is also provided with sliding grooves 141 that penetrate the U-shaped slide plate 140 at intervals, and the fixing screw 152 is also arranged in the sliding groove 141.

[0073] By disposing the second connecting column 150 , the U-shaped slide plate 140 is slidably disposed between the second connecting column 150 and the fixing screw 152 through the sliding groove 141 , thereby improving the stability of sliding the air pressure conversion shaft 130 through the U-shaped slide plate 140 .

[0074] See also Figure 2 As shown, the inflatable and deflable film pump also includes an air pressure detection device, which includes a sensor sleeve 161, a sensor 163 and an air pressure detection plate 162. An air pressure hole 160 is provided on the connecting platform 121 on the side away from the second connecting column 150. The air pressure hole 160 is connected to the air nozzle 123. The sensor sleeve 161 is plugged into the air pressure hole 160. The first surface of the air pressure detection plate 162 is provided with a sensor 163, and the sensor 163 is plugged into the sensor sleeve 161.

[0075] Since the air pressure hole 160 is connected to the air nozzle 123, when the inflatable and deflable membrane pump is performing vacuuming or inflating work, air will flow into the air pressure hole 160, and the sensor 163 determines whether the inflatable and deflable membrane pump is working normally by detecting the air pressure, thereby improving the efficiency of maintenance and inspection of the inflatable and deflable membrane pump.

[0076] See also Figure 2As shown, the air pressure detection device also includes a reinforcing screw 164 and a protrusion 167. The reinforcing screw 164 is arranged on the second surface of the air pressure detection plate 162 and penetrates the air pressure detection plate 162. The connecting platform 121 is also spaced apart on the side away from the second connecting column 150 with an integrally extended connecting wall 165. The connecting wall 165 is provided with a second threaded hole 166. The reinforcing screw 164 is also assembled in the second threaded hole 166. The protrusion 167 is arranged on the connecting wall 165 on the side away from the second connecting column 150. The air pressure detection plate 162 is also spaced apart with grooves 168. The grooves 168 are arranged corresponding to the protrusions 167. When the air pressure detection plate 162 is assembled on the connecting wall 165, the protrusions 167 are located in the grooves 168.

[0077] By setting the reinforcing screws 164, the stability of the assembly of the air pressure detection plate 162 in the direction perpendicular to the air pressure detection plate 162 is improved, and by setting the protrusions 167 and the grooves 168, the stability of the assembly in the direction parallel to the plane where the air pressure detection plate 162 is located is improved.

[0078] See also Figure 2 As shown, the inflatable and deflable membrane pump further includes a docking platform 170 and a docking groove 171 .

[0079] The docking platform 170 is arranged on the second surface of the base 120, and the docking platform 170 is arranged at intervals on the four sides of the base 120. The docking groove 171 is arranged on the four sides of the movement body 100 close to the base 120. The docking groove 171 is arranged corresponding to the docking platform 170. Through the arrangement of the docking platform 170 and the docking groove 171, the accuracy of the assembly connection between the air pressure conversion component and the movement body 100 is improved.

[0080] See also Figure 2 As shown, the sealing sheet 110 includes a straight plate portion 112 provided with an air hole 113 and a convex plate portion 111 provided on a side away from the air hole 113. The shape of the air groove 101 is the same as that of the sealing sheet 110. By performing fool-proof treatment on the sealing sheet 110, the sealing sheet 110 is prevented from being assembled in reverse, thereby improving the accuracy of the overall assembly.

[0081] To sum up, the inflatable and deflable diaphragm pump provided in the present application can be inflated and switched to exhaust operation through the same air nozzle through the setting of the air pressure conversion component, thereby improving the versatility of the inflatable and deflable diaphragm pump, and the overall structure is compact and small in size, which reduces the space occupied during use and reduces the production cost.

[0082] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
