The invention provides a sealing detection device.

1 and 2, the seal detection device 10 is used to detect the seal of the container with the filling port 20. There are many kinds of containers with the filling port 20, such as: drinking machines, water dispensers, electric kettles, etc., the following The above content will be explained with the water dispenser as an example. When testing the tightness of the pipeline system of the water dispenser, it is necessary to cooperate with the gas source and gas testing equipment to complete it. When testing the drinking water pipeline system, on the one hand, the gas source introduces gas into the sealing detection device 10, and the sealing detection device 10 expands, thereby blocking the filling port 20 of the water dispenser; on the other hand, the gas source introduces gas into In the pipeline system of the water dispenser, the air detection equipment detects the change of the air pressure in the pipeline system to determine whether the detected pipeline sealing system is leaking.

In the embodiment of the present invention, as shown in Fig. 3 to Fig. 5, a seal detection device 10 is used for the seal detection of a container with a spout 20, and the seal detection device 10 includes: a fixed seat 11, the fixed seat 11 is provided with a first air channel 111 that runs through the upper end surface and the lower end surface of the fixed seat 11; It expands outward along the outer circumference of the fixing seat 11 to seal against the inner wall of the filling mouth 20 of the container.

The annular inflatable airbag 12 itself has an inner cavity for containing gas, and when the inner cavity of the annular inflatable airbag 12 is inflated, the annular inflatable airbag 12 itself expands. Here, the annular inflatable airbag 12 is made of flexible parts, such as silicone, latex, polyurethane and the like. The fixing base 11 is substantially cylindrical, and the first air channel 111 extends from top to bottom to penetrate the upper and lower end surfaces of the fixing base 11 (for example, the first air channel 111 extends along the axial direction of the fixing base 11 ). The first air channel 111 is used to inflate the water dispenser. Inflating the annular inflatable airbag 12 is through the second air passage 112, the second air passage 112 can penetrate from the upper end surface of the fixed seat 11 to the outer peripheral surface of the fixed seat 11, and the annular inflatable airbag 12 is provided with a through hole, the through hole Just communicate with the second airway 112 . It is also possible that the wall of the annular inflatable air bag 12 is provided with an air inlet hole, and an air inlet pipe 13 is inserted in the air inlet hole, and the air inlet pipe 13 and the air inlet hole form the second air channel 112 . Of course, in order to make gas injection more convenient, the second air channel 112 passing through the upper end surface of the fixing seat 11 and the outer peripheral surface of the fixing seat 11 is a preferred embodiment.

When the sealing detection device 10 detects the water dispenser, at first, the gas source introduces the gas through the second air channel 112 into the annular inflatable air bag 12, and when the annular inflatable air bag 12 expands to a certain degree, the filling port 20 of the water dispenser It is sealed; at this time, the gas source supplies air to the first air channel 111, and the gas enters the pipeline of the water dispenser from the first air channel 111 through the filling port 20. Then detect the change of the air pressure in the filling mouth 20 in a period of time (such as one minute, five minutes or ten minutes) by the air detection device, if the air pressure change value exceeds the preset range, it can be determined that the water dispenser pipeline system is leaking. On the contrary, there is no air leakage. The above-mentioned fixing base 11 may be hollow or solid. For the hollow fixed seat 11, the first air channel 111 can be an air duct passing through the upper and lower end surfaces of the fixed seat 11, and the entire cavity of the hollow fixed seat 11 can be a part of the second air channel 112 . In this way, the inner cavity can buffer the annular inflatable airbag 12, and the air pressure in the annular inflatable airbag 12 can maintain a relatively stable state. Excessive gas pressure is not easy to cause damage to the annular inflatable airbag 12, even if the air pressure in the annular inflatable airbag 12 is relatively small, the annular inflatable airbag 12 will not collapse quickly.

In addition, the fixing seat 11 can maintain the expansion direction of the annular inflatable air bag 12 . When the annular inflatable airbag 12 is inflated, the annular inflatable airbag 12 expands outwardly on the periphery of the fixing seat 11, so that the filling port 20 can be blocked in a short time.

According to the technical solution of the present invention, an annular inflatable airbag 12 is sheathed on the outer periphery of the fixed seat 11, and the annular inflatable airbag 12 can be inflated to different specifications by inflating the annular inflatable airbag 12, so that it can be adapted to containers of various sizes of filling ports 20 , improving the versatility of the sealing detection device 10 .

Continuing to refer to FIG. 3 to FIG. 5 , during the detection process of the sealing detection device 10 , the annular inflatable air bag 12 is in sealing contact with the inner wall of the filling port 20 on the one hand, and is in contact with the peripheral wall of the fixing seat 11 on the other hand. However, the fixing seat 11 may escape from the annular inflatable air bag 12 under its own gravity or external force, causing the sealing detection device 10 to lose its detection function. In this embodiment, the outer peripheral surface of the fixing seat 11 defines an annular groove 113 extending along the circumferential direction of the fixing seat 11 , and the annular inflatable air bag 12 is disposed in the annular groove 113 . In this way, the cooperation between the annular inflatable air bag 12 and the fixing seat 11 is more firm. In addition, under the action of the annular groove 113 , the expansion direction of the annular inflatable air bag 12 is more uniform, so that the sealing performance of the sealing detection device 10 on the filling port 20 is better.

The annular groove 113 has an upper wall, a lower wall, and a bottom connecting the upper wall and the lower wall. After the annular inflatable airbag 12 is inflated, the annular inflatable airbag 12 abuts against the bottom wall of the annular groove 113 , thereby preventing leakage of the detection gas (the gas flushed into the filling port 20 from the first air channel 111 ). However, once the pressure of the test gas is too high, the test gas may leak from the middle between the annular inflatable air bag 12 and the bottom surface of the annular groove 113 . In one embodiment, ribs (not shown in the figure) extending along the circumferential direction of the fixing seat 11 are provided on the upper wall surface or the lower wall surface of the annular groove 113, and the ribs are used for When the inflatable airbag 12 is inflated, it is in sealing contact with the annular inflatable airbag 12 . In this way, when the annular inflatable airbag 12 is inflated, the sealing effect between the ribs and the annular inflatable airbag 12 is better, thereby improving the tolerance of the seal detection device 10 to the pressure in the filling port 20, and the detection accuracy of the seal detection device 10 higher.

With reference to Fig. 4 and Fig. 5, above-mentioned embodiment mentions that the second air channel 112 that runs through the upper end surface of the fixed seat 11 and the outer peripheral surface of the fixed seat 11 is opened in the fixed seat 11, and the second air channel 112 is connected with the annular air-filled cavities connected. On the basis of this embodiment, in order to make the annular inflatable airbag 12 maintain directional expansion (to avoid the annular inflatable airbag 12 moving up and down) when inflated, an inflatable tube 13 is arranged on the annular inflatable airbag 12, and the inflatable tube 13 is from the The outer peripheral surface of the fixing seat 11 is inserted into the fixing seat 11 to communicate with the second air channel 112 . When inflated, driven by the gas, the possible parts of the annular inflatable airbag 12 are displaced up and down. If the annular inflatable airbag 12 has this displacement before it is full of gas, then after the annular inflatable airbag 12 is full of air, it will be affected by the pressure on the one hand. The abutment effect of the inner wall of the filling port 20, on the other hand, is subject to the friction force of the peripheral wall of the fixed seat 11, the annular inflatable air bag 12 may be difficult to return (the annular inflatable air bag 12 is skewed as a whole), and then on the one hand may cause the annular inflatable air bag 12 to be in contact with the filling Poor sealing of the inner wall of the port 20 may, on the other hand, lead to leakage of the detection gas, thus affecting the measurement accuracy of the seal detection device 10 . Here, after the air intake pipe 13 is provided, the air intake pipe 13 can position the annular inflatable air bag 12, so as to avoid the annular inflatable air bag 12 from being skewed after being inflated. Furthermore, the accuracy of the sealing detection device 10 is improved.

6 and 7, in the previous embodiment, in order to improve the airtightness of the connection between the intake pipe 13 and the second air passage 112, the second air passage 112 has a An air outlet, the outer peripheral surface of the fixing seat 11 is provided with an annular installation groove 114 surrounding the air outlet, and the inflation tube 13 is inserted into the annular installation groove 114 . Here, the annular installation groove 114 has an inner peripheral wall close to the second air passage 112 and an outer peripheral wall far away from the second air passage 112. When the air intake pipe 13 is inserted into the annular installation groove 114, the inner wall of the air intake pipe 13 It abuts against the inner peripheral wall of the annular installation groove 114 , so as to prevent the gas in the inflatable airbag from leaking from the intake pipe 13 .

Referring to Figures 8 to 10, on the basis of the previous embodiment, in order to further increase the sealing performance between the intake pipe 13 and the annular installation groove 114, the outer peripheral wall is provided with an annular pressing portion extending along its circumference 115 , the annular pressing portion 115 presses the inflation tube 13 against the inner peripheral wall. Here, the pressing part 115 can be a flexible part, such as rubber, silica gel or other plastic parts. It is also difficult to leak from the annular installation groove 114 after entering the annular installation groove 114 . In addition, the pressing part 115 can be a hard part, and the air intake pipe 13 can be firmly pressed against the inner peripheral wall of the annular installation groove 114 through the annular pressing part 115 .

11 to 13, on the basis of the previous embodiment, in order to further strengthen the sealing effect of the annular pressing portion 115, in this embodiment, the annular pressing portion 115 is a flexible piece, and the annular pressing portion The pressure portion 115 is inclined towards a direction away from the air outlet. In this way, even if there is air leakage between the intake pipe 13 and the inner peripheral wall of the annular installation groove 114, after the leaked gas enters the annular installation groove 114, the part of the gas generates air pressure, and then pushes the annular pressing part 115 to move toward the direction of the air outlet, thereby , the pressing force between the pressing portion 115 and the outer wall of the intake pipe 13 increases, and it is difficult for gas to leak from between the annular pressing portion 115 and the intake pipe 13 .

Considering that the distance between the sealing detection device 10 and the side wall of the filling port 20 of the water dispenser is not large, it is difficult for the user to transfer the sealing detection device 10 to the position of the filling port 20 before the detection; Transfer away from filling mouth 20. In a preferred embodiment, in order to facilitate the transfer of the seal detection device 10 , a handle 15 is also installed on the fixing base 11 .

After the gas source introduces the gas into the second gas channel 112, the gas pressure needs to be kept stable, otherwise the gas detection device cannot detect accurately. In one embodiment, the fixed seat 11 is further provided with an intake control valve 14 communicating with the second air passage 112 . When gas needs to be introduced into the second airway 112, the intake control valve 14 is opened, and when the gas fills the annular inflatable airbag 12 and the filling port 20 is blocked, the intake control valve 14 can be closed.

The above is only a preferred embodiment of the present invention, and does not therefore limit the patent scope of the present invention. Under the inventive concept of the present invention, the equivalent structural transformation made by using the description of the present invention and the contents of the accompanying drawings, or direct/indirect use All other relevant technical fields are included in the patent protection scope of the present invention.
