Description

Technical Field

[0001] This utility model relates to the field of air pressure monitoring technology, and in particular to a more versatile external air pressure monitoring meter. Background Technology

[0002] Larger inflatable devices such as air mattresses and inflatable boats are equipped with inflation valves. For example, a Chinese utility model patent with application number 201520486601.8 (authorization announcement number 204784890U) discloses an inflation valve for inflatable products, including a valve seat and a valve body. The valve body has an upper air chamber and a lower air chamber, which are interconnected by a valve port. An inflation one-way valve core assembly is provided at the valve port. The inflation one-way valve core assembly includes a valve stem, with a valve plate made of flexible material at the lower end of the valve stem. The inner wall of the valve port is formed with cross-arranged connecting ribs. The valve stem moves through the cross-connection of the connecting ribs. The valve plate is located in the lower air chamber. A blocking element is provided on the valve stem located in the upper air chamber to prevent the valve stem from falling. This one-way valve core assembly has the advantages of simple structure and easy assembly. During inflation, the valve plate opens under the action of air pressure, and the gas enters the lower air chamber after passing through the valve port. When inflation is finished, the valve plate in the lower air chamber is kept closed by the air pressure inside the inflation device to prevent air leakage.

[0003] Another Chinese utility model patent with patent application number CN202020974374.4 (authorization announcement number CN212389809U) discloses an inflation valve, which includes a valve body and a valve cover. The valve body is provided with an inner shell and an outer shell. The inner shell is provided with an inflation chamber and an inflation valve port. The outer shell is provided with a working chamber. The inflation chamber and the working chamber are connected through the inflation valve port. A one-way valve core assembly is provided at the inflation valve port. The valve cover is detachably mounted on the valve body. The valve cover covers the opening of the inflation chamber (102).

[0004] To ensure the effectiveness of inflatable products, users often need to measure the air pressure inside to determine if the product is adequately inflated. During inflation, the air pump usually has a built-in pressure display, making this easy to handle. However, it's inconvenient to check the internal pressure of inflatable products during use. Therefore, some inflatable products are equipped with an additional pressure display valve, which increases the cost of the product.

[0005] Therefore, how to design a more versatile external pressure monitoring gauge that can be used with different inflation valves is a technical problem that urgently needs to be solved by those skilled in the art. With this pressure monitoring gauge, there is no need to configure an additional pressure display valve on the inflation product. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an external pressure monitoring meter that is easier to operate and more versatile, in view of the current state of the technology. This more versatile external pressure monitoring meter can be adapted to inflation valves of different structures.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a more versatile external air pressure monitoring meter, which is connected to the inflation valve on an inflatable product, including a meter body for measuring the air pressure inside the inflatable product, the meter body being provided with a first connecting seat; a meter base, on which a second connecting seat is provided, the first connecting seat and the second connecting seat being detachably connected, and the meter base being provided with a plug-in mechanism for inserting into the inflation valve.

[0008] Preferably, the first connecting seat and the second connecting seat are connected by a threaded connection or a snap-fit ​​connection.

[0009] Preferably, the insertion mechanism includes a first insertion part disposed at the lower part of the gauge base and used to insert into the valve body of the inflation valve. The first insertion part contains a second gas chamber communicating with the interior of the gauge body. A stop rod is disposed at the lower end face of the first insertion part, and the stop rod is used to open the valve plate on the inflation valve, thereby opening the valve port and allowing communication between the interior of the inflatable product and the second gas chamber. Using the above solution, connecting the gauge body to the gauge base provided in this embodiment forms a first type of air pressure monitoring gauge, which can be used to measure the air pressure inside an inflation valve adapted to the insertion mechanism.

[0010] Preferably, the insertion mechanism includes a second insertion part disposed at the lower part of the gauge base and used for insertion into the inflation valve. The second insertion part has a second gas chamber communicating with the interior of the gauge body. A second slot is disposed on the side wall of the second insertion part and is used to engage with the valve body to open the valve port, thereby allowing the interior of the inflatable product to communicate with the second gas chamber. Using the above scheme, connecting the gauge body to the gauge base in this embodiment forms a second type of air pressure monitoring gauge, which can be used to measure the air pressure inside the inflation valve adapted to the insertion mechanism.

[0011] Preferably, the gauge body includes a housing with an installation cavity and a first gas chamber connecting the installation cavity to the outside. The lower port of the first gas chamber is connected to a second gas chamber. A pressure monitoring component is disposed within the installation cavity and located at the upper port of the first gas chamber. The pressure monitoring component is used to measure the pressure inside the first gas chamber. The interior of the inflatable product is connected to the second gas chamber, and the second gas chamber is connected to the first gas chamber. When the pressure monitoring gauge is connected to the inflation valve, the gas inside the inflatable product flows sequentially to the second gas chamber and the first gas chamber. The pressure monitoring component measures the pressure inside the first gas chamber, thereby indirectly measuring the internal pressure of the inflatable product.

[0012] Preferably, the bottom wall of the mounting cavity is provided with an upwardly extending first protrusion, and the first gas chamber passes through the first protrusion vertically.

[0013] Preferably, the air pressure monitoring component includes a circuit board, which is horizontally disposed above the first boss; a sensor disposed on the lower part of the circuit board, and the sensor is facing the first gas chamber and used to measure the air pressure in the first gas chamber; a display screen disposed on the upper part of the circuit board and used to display the air pressure value; and a micro switch disposed on the upper part of the circuit board and used to control the opening and closing of the display screen.

[0014] Preferably, the air pressure monitoring component further includes a battery disposed at the lower part of the circuit board and housed in the gap between the outer wall of the first boss and the inner wall of the mounting cavity.

[0015] Preferably, the meter body further includes a cover that mates with the housing. A mounting hole is provided on the cover corresponding to the position of the micro switch, and a button for pressing the micro switch is installed in the mounting hole. With this design, air pressure can only be measured when the micro switch is turned on, which helps reduce battery power consumption.

[0016] Preferably, the first boss is connected to the circuit board by screws, and a first sealing ring is provided between the top surface of the first boss and the bottom surface of the circuit board.

[0017] Compared with the prior art, the advantages of this utility model are: the more versatile external barometric pressure monitoring meter includes a detachable body and a base. When the body is connected to a base of a certain type, it can measure the inflation valve that is compatible with the structure of the base, thereby improving the versatility of the external barometric pressure monitoring meter.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] like Figures 1-6 The above is a preferred embodiment of the more versatile external pressure monitoring meter of this utility model. The more versatile external pressure monitoring meter mainly includes a meter body 1 and a meter base 2 that is detachably connected to the meter body 1. When the meter base 2 is connected to the inflation valve on the inflatable product, the more versatile external pressure monitoring meter can measure the air pressure inside the inflatable product.

[0030] like Figures 3-5As shown, the meter body 1 includes a first connecting seat 11, a housing 12, a barometric pressure monitoring component 13, and a meter cover 14. The lower end face of the housing 12 has a downwardly extending first connecting seat 11. The first connecting seat 11 has an opening inside for partial insertion of the meter base 2. The side wall of the first connecting seat 11 has a first slot 111 for engaging with the meter base 2. The upper part of the housing 12 has an upward-opening mounting cavity. The bottom wall of the mounting cavity has an upwardly extending first boss 121. The first boss 121 has a first gas chamber 121a extending vertically through it. The gap between the outer wall of the first boss 121 and the inner wall of the mounting cavity is an outer chamber 121b. The space of the outer chamber 121b is used to install part of the barometric pressure monitoring component. The air pressure monitoring component 13 is disposed within the mounting cavity and specifically includes a circuit board 131, a sensor (not shown in the figure), a display screen 132, a micro switch 133, and a battery 134. The circuit board 131 is horizontally disposed above the first protrusion 121. The sensor is disposed on the lower end face of the circuit board 131, facing the first gas chamber 121a and used to measure the air pressure in the first gas chamber 121a. The display screen 132 is disposed on the upper end face of the circuit board 131 and used to display the air pressure value. The micro switch 133 is disposed on the upper end face of the circuit board 131 and used to control the opening and closing of the display screen 132. The battery 134 is disposed below the circuit board 131 and is housed within the outer chamber 121b. A cover 14 is disposed on the upper end of the housing 12 to encapsulate the air pressure monitoring component 13 within the housing 12. A mounting hole 141 is provided on the cover 14 at the position corresponding to the micro switch 133, and a button 142 for pressing the micro switch 133 is installed in the mounting hole 141. The user presses the micro switch 133 via button 142 to control the opening and closing of the display screen 132.

[0031] Furthermore, a second protrusion 122 extending upward is provided on the bottom wall of the outer chamber 121b, and a first connecting hole 1221 extending vertically is provided inside the second protrusion 122. A second connecting hole 1311 is correspondingly provided on the circuit board 131. Screws pass through the first connecting hole 1221 and the second connecting hole 1311 to connect the circuit board 131 to the second protrusion 122. In order to improve the sealing performance of the upper port of the first gas chamber 121a, a first sealing ring 15 is provided between the upper end face of the first protrusion 121 and the lower end face of the circuit board 131.

[0032] The upper end of the watch base 2 is provided with an upward-opening second connecting seat 20. The side wall of the second connecting seat 20 is provided with a locking post 201 that is adapted to the first locking groove 111 of the first connecting seat 11. The second connecting seat 20 on the watch base 2 is inserted into the opening of the first connecting seat 11 on the watch body 1. The second connecting seat 20 is rotated relative to the first connecting seat 11, so that the locking post 201 is engaged in the first locking groove 111, thereby connecting the watch body 1 and the watch base 2 together. This buckle connection is a common technical means.

[0033] The lower end of the gauge base 2 is provided with a plug-in mechanism for connecting to the valve body of the inflation valve. This plug-in mechanism includes a first plug-in portion 211 and a stop rod 212. The first plug-in portion 211 is located at the lower part of the gauge base 2 and is used to insert into the valve body of the inflation valve. A second gas chamber 2a, communicating with a first gas chamber 121a, is located within the first plug-in portion 211. The stop rod 212 is located at the lower end face of the first plug-in portion 211 and is used to open the valve plate on the inflation valve, thereby opening the valve port and allowing communication between the interior of the inflated product and the second gas chamber 2a. Using the above scheme, connecting the gauge body 1 to the gauge base 2 with the plug-in mechanism forms a first type of air pressure monitoring gauge. This air pressure monitoring gauge can be used to measure the air pressure inside an inflation valve (i.e., the inflation valve disclosed in patent publication number 204784890U) that is compatible with the plug-in mechanism. In other words, the interior of the inflatable product is connected to the second gas chamber 2a, and the second gas chamber 2a is connected to the first gas chamber 121a. When the pressure monitoring gauge is connected to the inflation valve, the gas inside the inflatable product flows sequentially to the second gas chamber 2a and the first gas chamber 121a. The pressure monitoring component 13 measures the pressure in the first gas chamber 121a, thereby indirectly measuring the internal pressure of the inflatable product.

[0034] Furthermore, to improve the sealing of the connection between the watch body 1 and the base 2, a second sealing ring 16 is provided on the inner top wall of the first connecting seat 11. When the watch body 1 and the base 2 are connected, the second sealing ring 16 abuts against the upper end face of the second connecting seat 20. A laterally extending baffle 202 is also provided on the side wall of the second connecting seat 20. The baffle 202 can facilitate the user to pick up the base 2 and prevent the base 2 from rolling around.

[0035] Example 2

[0036] The only difference from Embodiment 1 is that the insertion mechanism provided at the lower end of the base 2 includes a second insertion part 221 and a slot 222, see [link to embodiment 1]. Figure 7 .

[0037] The second insertion part 221 is disposed at the lower part of the gauge base 2 and is used to insert into the valve body of the inflation valve. The second insertion part 221 is provided with a second gas chamber 2a that communicates with the interior of the gauge body 1. The slot 222 is disposed on the side wall of the second insertion part 221 and is used to engage with the valve body to open the valve port so that the interior of the inflatable product communicates with the second gas chamber 2a. Using the above solution, after connecting the gauge body 1 with the gauge base 2 of this embodiment, a second type of air pressure monitoring gauge is formed. This air pressure monitoring gauge can be used to measure the air pressure in the inflation valve (i.e., the inflation valve disclosed in the patent with authorization announcement number CN212389809U) that is compatible with the insertion mechanism.

[0038] The external barometric pressure monitoring meter disclosed in this utility model has greater versatility. It includes a meter body 1 and two types of meter bases 2. When the meter body 1 is connected to any one of the meter bases 2, it can measure the inflation valve that is compatible with the structure of the meter base, thereby improving the versatility of the external barometric pressure monitoring meter.

[0040] The only difference from Embodiment 1 is that the outer peripheral wall of the first connecting seat 11 on the watch body 1 is provided with an internal thread 110, and the inner peripheral wall of the second connecting seat 20 on the watch base 2 is provided with an external thread 203. The first connecting seat 11 and the second connecting seat 20 are connected together by the internal and external threads, as shown below. Figure 8 As shown.
