[0033] As shown in Figures 1-2 A glove leak detector provided by the utility model mainly comprises a sealed base 100, an installation cavity and an installation seat are arranged on the sealed base 100; a power supply assembly 1012 is used for power supply of the whole instrument, and comprises a power supply base, a plurality of batteries are arranged in the power supply base, the power supply base is arranged on the sealed base 100, the plurality of batteries are arranged in a POM shell, two power supply contacts and two temperature contacts are inlaid on the POM shell and connected with the power supply base. A detection host is arranged on the sealed base 100, and a control mainboard is arranged on the detection host; the control mainboard is arranged in the installation cavity of the sealed base 100, a plurality of communication connection ports and read-write ports are arranged on the control mainboard, for example, the communication connection ports comprise a USB-A interface, an HMI interface, a power supply interface, an insurance interface, an LED lamp interface, a WI-FI / BT interface, a BLUETOOTH interface, a printer interface, a solenoid valve interface, a diaphragm pump interface, a buzzer interface, an RS232 / RS485 communication interface, a battery and a temperature interface; the control host further comprises a plurality of control components, and the plurality of control components are connected with the above-mentioned ports one by one through the wiring terminals. The plurality of components are convenient to install, simple to maintain and low in failure rate; the read-write ports are mainly used for input of software control language programs, direct reading and writing of signals of various components, and do not have communication and connection problems, thereby ensuring stability.

[0034] As shown in Figure 3 A sealing ring 1011 is arranged on the sealed base 100, a first air inlet 1013 is arranged on the sealing ring 1011, a first air charging port 1014 is arranged on the sealed base 100, and the sealing ring 1011 can expand when air charging, so as to be sealed and abutted with a glove seat 500 of a glove to be detected.

[0035] The air pump assembly is arranged in the mounting cavity of the sealing base 100, and is used for air charging. The air pump assembly is connected with the first air inlet 1013 and the first air charging port 1014 respectively, and is in communication connection with the control mainboard, so as to realize automatic control. The first air inlet 1013 is used for air charging and discharging of the sealing ring 1011, and the first air charging port 1014 is used for air charging and discharging of the glove to be detected.

[0036] Through the above arrangement, the plug-in connection of each control element with the control mainboard can be facilitated, and complex wiring is not needed. Meanwhile, the control mainboard can input a control program. Compared with a customized control board in the market, the control mainboard can be reused by replacing the control program, without the need of repeated installation and fixation in the narrow space of the sealing base 100, and maintenance is simple and operation is convenient. Meanwhile, the battery assembly 1012 is externally arranged, so that the battery can be replaced, thereby avoiding the need of external power supply every time the battery is used, and avoiding the trouble of replacing the battery due to battery aging. Meanwhile, one instrument can be equipped with multiple batteries, so that the work efficiency is not affected due to waiting for charging because of no battery power.

[0037] In one embodiment, since the glove leak detector needs to charge two spaces, one is the sealing ring 1011, and the other is the glove to be detected. The sealing ring 1011 has a small inflation volume, and one air pump can meet the air charging requirement. However, the glove has a relatively large inflation volume, and one air pump cannot quickly charge the glove to be detected in a period of time. Therefore, a double-pump structure is adopted. Figure 4 As shown in the figure, specifically, the air pump assembly includes a first air pump 4013 and a second air pump 4023, which are connected in parallel. When the sealing ring 4011 is charged, only one air pump is needed to quickly complete the charging. When the glove needs to be charged, the first air pump 4013 and the second air pump 4023 work simultaneously to quickly charge the glove. When the internal pressure of the glove approaches the target pressure value, the first air pump 4013 or the second air pump 4023 is closed, and only one air pump works, so that the target pressure value can be accurately controlled. Meanwhile, the air volume used in the process of regulation is small, and one air pump can meet the requirement.

[0038] In addition, the double-pump parallel structure can also complete the detection work with one air pump when one of the air pumps fails. Although the detection period may be lengthened, the detection process will not stop, the fault tolerance is improved, and the detection efficiency is ensured.

[0039] In one embodiment, in order to avoid too many pipes connected in the instrument, a gas path module is further provided, which is provided with a first gas path, a second gas path, a third gas path and a fourth gas path. The first gas path and the second gas path are communicated, and the first connecting point 4031 is arranged on the first gas path and the second connecting point 2403 is arranged on the second gas path. The third gas path and the first gas path are communicated, and the third connecting point 4033 is arranged on the third gas path. The fourth gas path and the second gas path are communicated, and the fourth connecting point 4034 is arranged on the fourth gas path. The third gas path and the fourth gas path are communicated and meet at a point, i.e. the fifth connecting point 4035, and the gas is discharged through the fifth connecting point 4035.

[0040] The first electromagnetic valve 4021 is arranged between the first connecting point 4031 and the third connecting point 4033, the second electromagnetic valve 4022 is arranged between the second connecting point 4032 and the fourth connecting point 4034, the third electromagnetic valve 4023 is arranged between the third connecting point 4033 and the fifth connecting point 4035, and the fourth electromagnetic valve 4024 is arranged between the fourth connecting point 4034 and the fifth connecting point 4035. The first gas pump 401 is connected to the first connecting point 4031, and the second gas pump 402 is connected to the second connecting point 4032. Through the above connection, the communication between the gas paths is realized. The first electromagnetic valve 4021, the second electromagnetic valve 4022, the third electromagnetic valve 4023 and the fourth electromagnetic valve 4024 are in communication connection with the control mainboard, so as to ensure the automatic control of the inflation process. The design of the gas path module greatly simplifies the connection of the external gas pipe, has small volume, is neat and stable in performance. In order to ensure the sealing property of the connection of the gas path module, an O-shaped sealing ring is used for sealing between the electromagnetic valve and the gas path module, so as to avoid the need of gluing or winding adhesive tape for the threaded column connection. Further, a pressure sensor is arranged in the gas path module, which is used for detecting the air pressure in the sealing ring and the air pressure in the glove to be detected.

[0041] In the specific operation, when the sealing ring 1011 is inflated, the first electromagnetic valve 4021 is opened, the second electromagnetic valve 4022, the third electromagnetic valve 4023 and the fourth electromagnetic valve 4024 are closed, and the air flow inflates the sealing ring 1011 through the first air inlet 1013.

[0042] When the glove is inflated, the first electromagnetic valve 4021 is closed, the third electromagnetic valve 4023 is closed, the fourth electromagnetic valve 4024 is closed, the second electromagnetic valve 4022 is opened, the first gas pump 401 and the second gas pump 402 are opened, and the air flow inflates the glove through the second electromagnetic valve 4022 and the first inflation port 1014.

[0043] When the sealing ring 1011 is deflated, the third electromagnetic valve 4023 is opened at this time, and the air flow is discharged to the outside through the first air inlet 1013 and the third electromagnetic valve 4023.

[0044] When the glove is vented, the fourth electromagnetic valve 4024 is opened, and the air flow is discharged to the outside through the first charging port 1014 and the fourth electromagnetic valve 4024.

[0045] In one embodiment, in order to avoid false detection, the sealing performance of the sealing ring 1011 of the glove leak detector is ensured, as shown in Figure 5 The self-detection seat 200 is further provided with a detection cavity 201, and the first detection port is arranged on the detection cavity 201. The shape of the first detection port matches the shape of the sealing ring 1011 laid on the sealing base 100. When the self-detection seat 200 approaches the coated sealing ring 1011, a preset gap is provided between the inner wall of the cavity of the self-detection seat 200 and the sealing ring 1011, and the self-detection seat 200 is sleeved on the sealing base 100. During detection, the sealing ring 1011 is inflated through the first air inlet 1013, so that it abuts against the inner wall of the self-detection detection cavity 201, and then the detection cavity is inflated through the first charging port 1014. Whether the air pressure in the detection cavity 201 is stable is checked, so as to confirm the sealing performance of the sealing ring 1011.

[0046] In one embodiment, in order to facilitate the replacement of the battery, as shown in Figure 6 The charging seat 300 is further provided with a charging control panel. The charging control panel is provided with a temperature detector, which is in communication connection with the charging control panel. The temperature detector monitors the temperature of the battery in real time. The current of the initial charging can be controlled to avoid the battery heating caused by excessive battery depletion and excessive charging current, thereby affecting the service life of the battery. The battery is charged in a constant voltage mode in the later stage of charging. The temperature of the battery cell is also monitored during the charging process, and the power supply is cut off when the temperature is too high. At the same time, the control mainboard can also monitor the temperature of the battery during use. The battery may overheat due to factors such as short circuit and overload, thereby causing danger. Therefore, the service life of the battery is ensured, and the cost is saved.

[0047] In one embodiment, in order to avoid manual input of glove codes, the FRID reading and writing device is arranged on the sealing base 100, and the information on the glove to be detected is identified through the FRID reading and writing device. Specifically, the information bar code, such as a two-dimensional code or a bar code, is arranged on the glove to be detected. When the glove to be detected approaches the sealing base 100, the FRID reading and writing device detects and scans to quickly read the label information prearranged on the glove, realizes automatic operation, avoids manual operation, reduces labor intensity, and reduces the error rate of glove information input. In this embodiment, the FRID reading and writing device is a prior art, and its function structure is similar to that of a scanner, which will not be described in detail here.

[0048] In one embodiment, the glove leak detector also has a manual deflation function. Specifically, a manual deflation button is arranged on the sealing base 100, one end of the manual deflation button abuts against the reset button of the third electromagnetic valve 4023, and by pressing the manual deflation button, the reset button of the third electromagnetic valve 4023 is reset, so that the third electromagnetic valve 4023 can work to deflate even in the case of power failure, thereby manually discharging the gas in the sealing ring 1011 and taking the glove seat 500 off the sealing base 100. During the operation of the glove leak detector, the sealing ring 1011 is first inflated, the glove inflation system of the glove leak detector and the glove port are sealed, a closed space is formed between the sealing base 100 of the glove leak detector and the glove, and then the glove is inflated for leak detection. If the glove leak detector is powered by a battery, the battery may run out after a long time of hanging up, so that the instrument cannot be taken off from the detected glove port. The manual deflation function of the sealing ring 1011 avoids the above risks.

[0049] In one embodiment, a glove size automatic identification function identification assembly is also included, which is arranged on the sealing base 100, and the glove size identification assembly includes two travel buttons which can be retracted. Specifically, the two travel buttons are a first button and a second button, and there are four cases as follows: first, no corresponding through hole is arranged on the sealing base 100, and both the first button and the second button are compressed, at this time, corresponding to the first glove size; second, only a first through hole is arranged on the sealing base 100, corresponding to the first button, at this time, only the second button is compressed, corresponding to the second glove size; when only a second through hole is arranged on the sealing base 100, the first button is compressed, at this time, corresponding to the third glove size; when both the first through hole and the second through hole are arranged on the sealing base 100, at this time, both the first button and the second button are not compressed, corresponding to the fourth glove size. Through the arrangement and combination of the two travel buttons, gloves of 12 inches, 10 inches, 8 inches and 7 inches can be automatically identified.

[0050] The above only describes the preferred embodiments of the present application, and it should be noted that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made. These improvements and refinements should also be considered within the scope of protection of the present application.
