Description

Technical Field

[0001] This application relates to the field of inflation technology, and more specifically, to an inflation monitoring device. Background Technology

[0002] There are many types of air guns on the market. The air gun is inserted into the air inlet of the container to be inflated and tightened. The air is then injected into the container using the pressure of an air compressor or air source to achieve inflation.

[0003] Existing air guns do not have built-in pressure monitoring capabilities. Therefore, to meet the requirement of monitoring inflation pressure, it is often necessary to connect an external pressure gauge via a separate pipeline for pressure monitoring. This monitoring method often requires assembling the air gun and pressure gauge during use, which is inconvenient. Utility Model Content

[0017] This application provides an inflation monitoring device, including a monitoring gauge with a gas channel. The gas channel, through an inlet and an outlet on the monitoring gauge, provides an inflation path for the inflation gas entering the container, thus enabling inflation of the container. Furthermore, a monitoring groove on the monitoring gauge houses a circuit board and a pressure sensor, and the circuit board directly seals the monitoring cavity between itself and the gas channel. This allows the pressure sensor to collect the gas pressure within the gas channel, integrating inflation and gas pressure monitoring functions into the inflation monitoring device. Moreover, the monitoring cavity is located beside the gas channel, and the pressure sensor is located within the monitoring cavity, which improves the smoothness of gas flow compared to placing the pressure sensor directly within the gas channel.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. It should be noted that, unless otherwise specified, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] One aspect of this application provides an inflation monitoring device 100, including a monitoring gauge 110 having a gas channel 1101. The monitoring gauge 110 has an air inlet 1106 and an air outlet 1107 respectively communicating with the gas channel 1101. A monitoring groove 1102 located beside the gas channel 1101 is provided on the monitoring gauge 110. A circuit board 111 is disposed in the monitoring groove 1102. The monitoring groove 1102 includes a monitoring cavity 1103 located between the circuit board 111 and the gas channel 1101. The monitoring cavity 1103 communicates with the gas channel 1101. The circuit board 111 cooperates with the inner wall of the monitoring groove 1102 to seal the monitoring cavity 1103. A pressure sensor 112 located in the monitoring cavity 1103 is disposed on the circuit board 111.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, the inflation monitoring device 100 includes a monitoring gauge 110, inside which is a gas channel 1101 that runs through the entire monitoring gauge 110 to facilitate gas flow. An air inlet 1106 and an air outlet 1107 are respectively provided at both ends of the monitoring gauge 110, and the air inlet 1106 and air outlet 1107 are respectively connected to the gas channel 1101. When inflation is required, gas enters from the air inlet 1106, passes through the gas channel 1101, and flows out from the air outlet 1107, thus entering the container to be inflated.

[0036] A monitoring groove 1102 is provided on the monitoring gauge 110, located beside the gas channel 1101. A circuit board 111 is disposed inside the monitoring groove 1102. The monitoring groove 1102 includes a monitoring cavity 1103 located between the circuit board 111 and the gas channel 1101. That is, the circuit board 111 divides a portion of the space within the monitoring groove 1102 as the monitoring cavity 1103 between the circuit board 111 and the gas channel 1101. The monitoring cavity 1103 communicates with the gas channel 1101. The circuit board 111 is sealed to the inner wall of the monitoring groove 1102, allowing the circuit board 111 to seal the monitoring cavity 1103. This sealing refers to blocking the path through which the gas channel 1101 communicates with the outside via the monitoring groove 1102. For example, sealant can be applied to the edge of the circuit board 111 to prevent gaps from forming between the circuit board 111 and the inner wall of the monitoring groove 1102, thus preventing gas leakage. A pressure sensor 112 is installed on the side of the circuit board 111 facing the monitoring chamber 1103. This sensor monitors the gas pressure as it flows through the gas channel 1101. When gas needs to be added to the container, the gas source is connected to the inlet 1106, and the container is connected to the outlet 1107. The gas source is turned on, and the gas flows through the inlet 1106 into the gas channel 1101, exits through the outlet 1107, and enters the container. Since the monitoring chamber 1103 is connected to the gas channel 1101, the gas enters the monitoring chamber 1103 as it flows through the gas channel 1101. At this time, the pressure sensor 112 on the side of the circuit board 111 facing the monitoring chamber 1103 can monitor the gas pressure, eliminating the need for a separate external pressure gauge and making pressure monitoring more convenient.

[0037] The monitoring groove 1102 is located beside the gas channel 1101. The circuit board 111 divides a portion of the space within the monitoring groove 1102 as a monitoring cavity 1103 between the circuit board 111 and the gas channel 1101, meaning the monitoring cavity 1103 is located beside the gas channel 1101. The pressure sensor 112 is located within the monitoring cavity 1103, which improves the smoothness of gas flow compared to placing the pressure sensor 112 directly within the gas channel 1101.

[0038] In some embodiments, the circuit board 111 is at a certain distance from the gas channel 1101. The distance referred to here means that the circuit board 111 should be positioned higher than the air inlet 1106 and air outlet 1107 located at both ends of the gas channel 1101, and should also be at a certain distance from the slot 1105 of the monitoring groove 1102, that is, it is positioned between the gas channel 1101 and the slot 1105 of the monitoring groove 1102.

[0039] In some implementations, the pressure sensor 112 may be a capacitive pressure sensor (which detects changes in capacitance by changing the distance between capacitor plates through air pressure), a resonant pressure sensor (which measures pressure by changing the frequency of a resonator through frequency changes), or an optical pressure sensor (which utilizes changes in optical properties (such as the refractive index of an optical fiber) caused by air pressure). The specific type used is not limited here.

[0040] It should be noted that the gas entering the monitoring chamber 1103 may contain moisture, which may affect the normal operation of the circuit board 111. Therefore, the circuit board 111 needs to be coated with conformal coating. Conformal coating can significantly improve the reliability and lifespan of the circuit board 111. The conformal coating can be of various types, such as acrylic resin, polyurethane resin, or silicone resin. The specific type used can be selected according to the specific situation, and no specific limitation is made here.

[0041] Optionally, a display panel 114 is provided at the opening 1105 of the monitoring groove 1102 to cover the opening 1105. The display panel 114 is electrically connected to the pressure sensor 112 via a circuit board 111.

[0042] Specifically, such as Figure 2 As shown, a display panel 114 is provided at the slot 1105 of the monitoring groove 1102, and the display panel 114 is fastened to the slot 1105. The display panel 114 is connected to the pressure sensor 112 via a circuit board 111. In use, the pressure sensor 112 monitors the pressure of the gas flowing through the gas channel 1101. This monitoring is usually represented by an electrical signal. The processor provided on the circuit board 111 receives the electrical signal output by the pressure sensor 112, processes the signal, converts it into a numerical signal, and outputs it to the display panel 114, so that the pressure value can be displayed on the display panel 114.

[0043] It should be noted that there is a gap between the circuit board 111 and the display panel 114, so that the circuit board 111, the display panel 114 and the inner wall of the monitoring groove 1102 form a receiving space. The receiving space can be used to place the battery 115, which is electrically connected to the pressure sensor 112, the circuit board 111 and the display panel 114.

[0044] In some embodiments, the display panel 114 can be fixed to the slot 1105 of the monitoring groove 1102 by means of screws 160, rivets, clips or sealant, etc., and the specific fixing method is not limited.

[0045] Optionally, a support base 1104 is provided in the monitoring groove 1102, the support base 1104 is located close to the inner wall of the monitoring groove 1102, and the board surface of the circuit board 111 is attached to the support base 1104.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, a support base 1104 is provided at the bottom of the monitoring groove 1102. The support base 1104 is located near the inner wall of the monitoring groove 1102 and is used to support the circuit board 111. In some embodiments, the support base 1104 can be located at the four corners of the bottom of the monitoring groove 1102, or it can surround the perimeter of the bottom of the monitoring groove 1102 (except for the positions of the air inlet 1106 and air outlet 1107), as long as it can stably support the circuit board 111.

[0047] In some embodiments, the circuit board 111 can be fixed to the support base 1104 by means of screws 160, rivets, or sealant, and the specific fixing method is not limited.

[0048] Optionally, the inflation monitoring device 100 further includes: a sealing shaft 120, which has a first air passage 1201. The first air passage 1201 is connected to the air outlet 1107 of the monitoring gauge 110 via the sealing shaft head 1202, and the sealing shaft tail 1203 is used to insert into the target object so as to communicate with the target object via the first air passage 1201; and a handle 130, which is slidably sleeved on the outer periphery of the sealing shaft 120 and can rotate relative to the sealing shaft 120. A connecting structure 1301 is provided on the handle 130, and the handle 130 is fixedly connected to the target object via the connecting structure 1301.

[0049] Specifically, such as Figure 3 and Figure 4 As shown, the inflation monitoring device 100 also includes a sealing shaft 120 connected to one end of the air outlet 1107 of the monitoring gauge 110. The sealing shaft 120 has a first air passage 1201 inside, which extends through the sealing shaft 120. The head 1202 of the sealing shaft communicates with the air outlet 1107 of the monitoring gauge 110, allowing the first air passage 1201 to communicate with the gas channel 1101 inside the monitoring gauge 110. The tail 1203 of the sealing shaft communicates with the target object. When inflation is required, gas enters the gas channel 1101 through the air inlet 1106 of the monitoring gauge 110, then enters the first air passage 1201 through the air outlet 1107 of the monitoring gauge 110, and finally enters the target object through the tail 1203 of the sealing shaft.

[0050] A handle 130 is fitted onto the sealing shaft 120. The handle 130 can move axially along the sealing shaft 120, either towards the head 1202 or the tail 1203 of the sealing shaft. It should be noted that a limit structure is provided on the outer circumferential surface of the sealing shaft 120 to prevent the handle 130 from slipping off the sealing shaft 120 during axial movement. Simultaneously, the handle 130 can also rotate axially along the sealing shaft 120. A connecting structure 1301 is provided at one end of the handle 130 near the tail 1203 of the sealing shaft, through which it is fixedly connected to the target object.

[0051] like Figure 8 The illustration shows a target object provided in an embodiment of this application. By rotating the handle 130, the handle 130 is fixedly connected to the target object via the connecting structure 1301, enabling a stable connection between the inflation monitoring device 100 and the target object. There are two ways to insert the sealing shaft tail 1203 into the target object: the first is to utilize the axial movement generated during the fixed connection of the handle 130 and the target object via rotation to drive the sealing shaft 120 into the target object; the second is to apply external force, such as manually, to the sealing shaft 120, so that after the sealing shaft 120 is inserted into the target object, the handle 130 is then fixedly connected to the target object via rotation and the connecting structure 1301. The order in which the sealing shaft 120 is inserted into the target object and the handle 130 is connected to the target object is not limited. For example, for... Figure 3 The inflation monitoring device 100 shown can be used by first inserting the tail of the sealing shaft 1203 into the target object, and then rotating the handle 130 to fix it to the target object via the connecting structure 1301. After the handle 130 is connected in place, the axial limiting between the handle 130 and the sealing shaft 120 prevents the tail of the sealing shaft 1203 from detaching from the target object.

[0052] By introducing gas into the air inlet 1106 of the monitoring meter 110, the gas passes through the gas channel 1101 and the first air passage 1201, enters the target object from the tail of the sealing shaft 1203, and enters the filling container in the direction indicated by the arrow.

[0053] It should be understood that the target object can be part of the container being filled. For example, the target object can be a component that enables the inflation monitoring device 100 to connect with the container being filled. The target object is located at the inflation port of the container being filled and is fixedly connected to the handle 130 on the inflation monitoring device 100. Alternatively, the target object can also be a component that enables the inflation detection device to switch on and off with the container being filled. Figure 8As shown, the handle 130 is fixedly connected to the target object by rotation and through the connecting structure 1301 via threads. The tail of the sealing shaft 1203 is inserted into the interior of the target object (at this time, it does not abut against the inner wall of the air passage in the target object). By introducing gas into the inflation monitoring device 100, the gas enters the target object through the sealing shaft 120 and enters the filling container through the air passage in the target object. When it is necessary to prevent gas flow, the tail of the sealing shaft 1203 is abutted against the inner wall of the air passage in the target object by external force, thereby preventing gas flow.

[0054] In some implementations, the connection structure 1301 can be an external thread or an internal thread, depending on the target object.

[0055] When the inflation monitoring device 100 is not in use, a protective cover 180 can be used to cover the tail of the sealing shaft 1203 and fixedly connected to the connecting structure 1301 on the handle 130 to prevent external debris from entering the first air passage 1201.

[0056] Optionally, the sealing shaft head 1202 is a square head, the air outlet 1107 is a square hole that fits into the square head, a sealing gasket 190 is provided between the square head and the square hole, and the sealing shaft 120 is fixedly connected to the monitoring instrument 110 via a flange 150.

[0057] Specifically, such as Figures 4 to 6 As shown, the air outlet 1107 of the monitoring gauge 110 is a square hole. Inserting the square head of the sealing shaft head 1202 into the air outlet 1107 prevents axial rotation of the sealing shaft 120. A sealing groove 1204 is provided at the end of the sealing shaft head 1202. By placing a sealing gasket 190 in the sealing groove 1204 and inserting the sealing shaft head 1202 into the air outlet 1107, the sealing gasket 190 prevents gas from flowing out from the connection. A flange 150 is fixedly provided on the outer periphery of the sealing shaft 120. For example, the flange 150 is interference-fitted or welded to the sealing shaft 120. The sealing shaft 120 is fixed to the end face of the air outlet 1107 of the monitoring gauge 110 by screws 160 passing through the outer peripheral through-hole of the flange 150.

[0058] Optionally, an operating part 170 is also fixedly sleeved on the outer periphery of the sealing shaft 120. The outer periphery of the operating part 170 is composed of multiple operating surfaces arranged at an angle. The operating part 170 is used for transmission constrained by external tools through the operating surfaces.

[0059] Specifically, such as Figure 3 and Figure 4As shown, an operating part 170 is also fixedly installed on the outer periphery of the sealing shaft 120. The operating part 170 is interference-fitted with the sealing shaft 120 and is located on the side of the flange 150 away from the monitoring gauge 110. A screw 160 passes through the operating part 170 and the flange 150, fixing the sealing shaft 120, operating part 170, and flange 150 together on the monitoring gauge 110. The outer periphery of the operating part 170 is composed of multiple operating surfaces, for example, five or six operating surfaces, distributed similarly to existing pentagonal or hexagonal nuts. It is fixed to the operating surface by an external tool. Rotating the external tool causes the sealing shaft 120, flange 150, and monitoring gauge 110 to rotate relative to the handle 130.

[0060] Optionally, the tail of the sealing shaft 1203 is a square head, which is used to mate with the square hole of the target object.

[0061] Specifically, such as Figure 4 , Figure 5 and Figure 7 As shown, the square head of the sealing shaft 1203 is inserted into the square hole of the target object. When the target object needs to rotate, rotating the sealing shaft 120 will cause the target object to rotate. For example, when the container being filled needs to achieve a switching function by rotating the target object, rotating the monitoring gauge 110 and the sealing shaft 120 together will drive the target object to rotate, thereby achieving gas flow. If faster gas flow is required, an external tool can be fixed to the operating surface. Rotating the external tool will quickly drive the monitoring gauge 110 and the sealing shaft 120 together to rotate the target object, thus accelerating the gas flow rate.

[0062] Optionally, the inflation monitoring device 100 further includes: a connector 140 having a second air passage 1401, the second air passage 1401 being connected to the air inlet 1106 of the monitoring gauge 110 via the connector tail 1403, and the connector head 1402 being detachably provided with a plug 141 for filling the second air passage 1401.

[0063] Specifically, such as Figure 4 As shown, the inflation monitoring device 100 also includes a connector 140 fixedly connected to the monitoring gauge 110. The connector 140 has a second air passage 1401 inside, which passes through the connector 140. The tail end 1403 of the connector is connected to the air inlet 1106 of the monitoring gauge 110, so that the second air passage 1401 is connected to the gas passage 1101 inside the monitoring gauge 110. The head of the connector 140 is also provided with a plug 141 for filling the second air passage 1401, and the plug 141 is detachably connected to the connector 140.

[0064] In some implementations, the monitoring gauge 110 and the connector 140 can be fixed by a threaded connection, a clamp connection, or a quick-connect connection; the specific connection method is not limited.

[0065] Connector 140, gauge 110, and sealing shaft 120 are fixedly connected as a whole. Rotating gauge 110 causes the whole assembly to rotate relative to handle 130. When it is necessary to monitor the static pressure inside the container being filled, plug 141 is inserted from connector head 1402 into the second air passage 1401, and sealing shaft tail 1203 is inserted into the container being filled. The handle 130 is then fixedly connected to the container via connecting structure 1301. At this time, pressure sensor 112 monitors the gas pressure in gas passage 1101, i.e., the static pressure. When it is necessary to monitor the dynamic pressure, plug 141 is pulled out from the second air passage 1401, and the gas source is connected to connector 140. The pressure monitored by pressure sensor 112 at this time is the dynamic pressure.

[0066] Anti-slip textures are provided on the outer surfaces of the handle 130 and the monitoring meter 110. When the handle 130 is fixedly connected to the target object or the container being filled by threads, and when the monitoring meter 110 needs to be rotated with the target object to realize the switching function, the anti-slip textures can increase friction and prevent slippage during rotation.

[0067] Optionally, a control switch 116 electrically connected to the circuit board 111 is provided on the display panel 114. The control switch 116 is used to control the working state of the display panel 114 and the pressure sensor 112.

[0068] Specifically, such as Figure 2 and Figure 4 As shown, control switch 116 is exposed on monitoring gauge 110, electrically connecting circuit board 111, pressure sensor 112, display panel 114, battery 115, and control switch 116. Control switch 116 can control whether display panel 114 displays pressure value and whether pressure sensor 112 starts gas pressure monitoring. For example, control switch 116 can control whether battery 115 powers display panel 114, thereby controlling its working state.

[0069] When pressure monitoring is required, turn on the switch, and the pressure value monitored by the pressure sensor 112 will be displayed on the display panel 114. When pressure monitoring is not required, turn off the switch.

[0070] In some implementations, the control switch 116 may be a push-button switch, a rotary switch, or a touch switch, and the specific type is not limited.

[0071] Optionally, a humidity sensor 113 located inside the monitoring cavity 1103 is also provided on the circuit board 111.

[0072] Specifically, such as Figure 2 As shown, the gas introduced into the gas channel 1101 will contain water vapor. The humidity of the gas can be monitored by setting a humidity sensor 113 on the circuit board 111. The humidity value detected by the humidity sensor 113 is displayed on the display panel 114. The specific connection method is the same as that of the pressure sensor 112, and will not be described in detail here.

[0073] In some embodiments, the humidity sensor 113 may be a capacitive humidity sensor 113 (which utilizes the change in the dielectric constant of the humidity-sensitive material with humidity, resulting in a change in capacitance), a resistive humidity sensor 113 (which utilizes the change in the resistance of the humidity-sensitive material with humidity), or a surface acoustic wave humidity sensor 113 (which utilizes the change in humidity to affect the propagation speed of sound waves on the surface of a piezoelectric material), etc. The specific type used is not limited here.

[0074] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
