[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1 to Figure 6 , which is the first embodiment of the utility model, provides a double-check valve sealing detection device, which includes a supporting component 100 and a detection component 200. Through the cooperation of the two, the lotion pump 103 can be automatically clamped and connected, and after the detection is completed, the clamping and connection of the lotion pump 103 can be automatically released, which greatly improves the efficiency of the double-check valve sealing detection.

[0031] Specifically, the support assembly 100 includes a support platform 101 , a support member 102 and a lotion pump 103 . The support member 102 is disposed on the top of the support platform 101 , and the lotion pump 103 is located on the support member 102 .

[0032] The support platform 101 is used to fix and support the support member 102. A box for containing clean water is arranged on the top of the support platform 101. The lower end of the lotion pump 103 extends under the surface of the clean water. When the double one-way valve in the lotion pump 103 has poor sealing performance and leaks, bubbles will be generated in the clean water. The support member 102 is used to support the lotion pump 103.

[0033] The detection component 200 is disposed on the support member 102 and includes a clamping member 201 , a driving member 202 and a detection member 203 . The clamping member 201 is disposed inside the support member 102 , the driving member 202 is located at one side of the support member 102 , and the detection member 203 is disposed on the top of the support member 102 .

[0034] The clamping member 201 is used to clamp and fix the lotion pump 103, and the driving member 202 is used to drive the clamping member 201 and the detecting member 203 to operate, so that the clamping member 201 first clamps and fixes the lotion pump 103, and then connects the detecting member 203 with the top of the lotion pump 103, and inflates the lotion pump 103. When the double one-way valve in the lotion pump 103 has poor sealing performance and leaks, bubbles will be generated in the clean water.

[0035] Specifically, the support member 102 includes a support column 102a and a support seat 102b. The support column 102a is fixed to the top of the support platform 101, and the support seat 102b is fixed to the top of the support column 102a.

[0036] The support column 102a is used to support the support base 102b, and the support base 102b is used to support the lotion pump 103.

[0037] Example 2

[0038] Reference Figure 1 and Figure 3 to Figure 5 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0039] Specifically, the clamping member 201 includes a supporting shaft 201a and a fixing clamp 201b. The supporting shaft 201a is fixed in the supporting seat 102b, and the fixing clamp 201b is rotatably connected to the surface of the supporting shaft 201a.

[0040] With the support of the support shaft 201 a , the fixing clamp 201 b can swing with the support shaft 201 a as a fulcrum, so that the fixing clamp 201 b can clamp and fix the lotion pump 103 .

[0041] Specifically, the clamping member 201 further includes a squeezing block 201c and a push rod 201d. The squeezing block 201c slides in the supporting seat 102b, and the push rod 201d is fixed to one side of the squeezing block 201c.

[0042] The pushing rod 201d pushes the squeezing block 201c, so that the squeezing block 201c squeezes the fixing clamp 201b, and thus the fixing clamp 201b clamps and fixes the lotion pump 103.

[0043] Specifically, the clamping member 201 also includes a first spring 201e and a second spring 201f. The two ends of the first spring 201e are respectively fixed to one side of the fixing clamp 201b and the inner wall of the support seat 102b. The two ends of the second spring 201f are respectively fixed to one side of the extrusion block 201c and the inner wall of the support seat 102b.

[0044] The first spring 201e is in a stretched state, and the second spring 201f is in a compressed state. When the thrust on the push rod 201d disappears, the pressing block 201c can drive the push rod 201d to move back under the action of the restoring elastic force of the second spring 201f, so that the pressing block 201c is away from the fixing clip 201b. At this time, under the action of the pulling force of the first spring 201e, the fixing clip 201b can be moved away from the lotion pump 103, thereby releasing the fixation of the lotion pump 103.

[0045] Specifically, the driving member 202 includes an air guide tube 202a and an air pump 202b. The air guide tube 202a is fixed to the top of the support seat 102b, and the air pump 202b is fixed to the end of the air guide tube 202a. An air guide groove U and an air release groove V are opened in the support seat 102b, and the air release groove V is located on one side of the air guide groove U.

[0046] By pressing the air pump 202b, the air in the air pump 202b can be transported to the air guide groove U through the air guide pipe 202a. At this time, the gas can push the push rod 201d in the air guide groove U, so that the push rod 201d pushes the extrusion block 201c to move. When the end of the push rod 201d moves to the side of the air discharge groove V, the fixing clip 201b fixes the lotion pump 103, and the air in the air guide groove U is discharged through the air discharge groove V.

[0047] Example 3

[0048] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0049] Specifically, the detection member 203 includes a column 203a and a fixing frame 203b, the column 203a is fixed to the top of the support seat 102b, and the fixing frame 203b is fixed to the top of the column 203a.

[0050] The column 203 a is used to fix and support the fixing frame 203 b , and the fixing frame 203 b is used to fix and support the detection member 203 .

[0051] Specifically, the detection member 203 further includes a connecting pipe 203c and a gas cylinder 203d. The two ends of the connecting pipe 203c are respectively fixed to the end of the air relief groove V and the top of the gas cylinder 203d. The gas cylinder 203d is fixed in the fixing frame 203b.

[0052] The connecting pipe 203c is used to transport the air output from the air release groove V to the gas cylinder 203d, which will rapidly increase the air pressure in the gas cylinder 203d.

[0053] Specifically, the detection component 203 also includes a bellows 203e, a connecting sleeve 203f, a third spring 203g and a delivery pipe 203h. The bellows 203e is fixed to the bottom of the gas cylinder 203d, the connecting sleeve 203f is fixed to the bottom of the bellows 203e, the two ends of the third spring 203g are respectively fixed to the bottom of the gas cylinder 203d and the top of the connecting sleeve 203f, the delivery pipe 203h is fixed to the top of the connecting sleeve 203f, the delivery pipe 203h slides in the gas cylinder 203d, and a through hole W is opened at the bottom of the gas cylinder 203d.

[0054] The third spring 203g is in a stretched state. When the air pressure in the gas cylinder 203d increases rapidly, the gas will be delivered to the bellows 203e through the through hole W, thereby increasing the air pressure in the bellows 203e, thereby causing the bellows 203e to stretch, thereby driving the connecting sleeve 203f to move toward the top of the lotion pump 103 until the connecting sleeve 203f and the top of the lotion pump 103 are connected together. A silicone gasket is provided at the connection between the connecting sleeve 203f and the top of the lotion pump 103 to ensure the sealing of the connection between the two. During the extension of the bellows 203e, the delivery pipe 203h slides on the gas cylinder 2 03d is used to limit the extension direction of the bellows 203e, so as to ensure that the connecting sleeve 203f can be connected to the top of the lotion pump 103. After the connecting sleeve 203f is connected to the top of the lotion pump 103, the high-pressure gas in the gas cylinder 203d will be delivered to the connection between the connecting sleeve 203f and the top of the lotion pump 103 through the delivery pipe 203h. If the double check valves in the lotion pump 103 have poor sealing performance, the lotion pump 103 will blow out continuous bubbles in the clean water at the bottom thereof. If the double check valves in the lotion pump 103 have good sealing performance, no continuous bubbles will be generated in the clean water at the bottom thereof.

[0055] Specifically, the detection component 203 further includes an air release pipe 203i, which is fixed to the surface of the gas cylinder 203d, and an air release hole X is opened in the air release pipe 203i.

[0056] When the air pressure in the gas cylinder 203d is higher than the external atmospheric pressure, the air in the gas cylinder 203d will be continuously discharged into the air through the air leakage hole X. Since the diameter of the air leakage hole X is small and the discharge capacity is limited, the high-pressure gas in the gas cylinder 203d will first push out the bellows 203e, so that the connecting sleeve 203f is connected to the top of the lotion pump 103, and the air tightness of the lotion pump 103 is tested.

[0057] During use, when the air tightness of the lotion pump 103 needs to be tested, the lotion pump 103 is first placed in the support seat 102b, and the lower end of the lotion pump 103 is located in the clean water. At this time, the air pump 202b can be quickly squeezed to allow the air in the air pump 202b to be transported to the air guide groove U through the air guide pipe 202a. At this time, the gas can push the push rod 201d in the air guide groove U, so that the push rod 201d pushes the squeezing block 201c to move, so that the squeezing block 201c can squeeze the fixing clamp 201b, so that the fixing clamp 201b clamps and fixes the lotion pump 103. When the end of the push rod 201d moves to the side of the air release groove V, the fixing clamp 201b has fixed the lotion pump 103, and the air in the air guide groove U will pass through the air guide pipe 202a. The air is discharged into the connecting pipe 203c through the air relief groove V. The connecting pipe 203c transports the air output from the air relief groove V into the gas cylinder 203d, which will rapidly increase the air pressure in the gas cylinder 203d. When the air pressure in the gas cylinder 203d rapidly increases, the gas will be transported into the bellows 203e through the through hole W, thereby increasing the air pressure in the bellows 203e, thereby extending the bellows 203e, thereby driving the connecting sleeve 203f to move toward the top of the lotion pump 103, until the connecting sleeve 203f and the top of the lotion pump 103 are connected together. If the double check valve in the lotion pump 103 has poor sealing performance, the lotion pump 103 will blow out continuous bubbles in the clean water at the bottom thereof. If the double check valve in the lotion pump 103 has good sealing performance, no continuous bubbles will be generated in the clean water at the bottom thereof.

[0058] After the detection, the air pump 202b is released. At this time, the thrust on the push rod 201d disappears. Under the action of the return elastic force of the second spring 201f, the squeezing block 201c can drive the push rod 201d to return and move, so that the squeezing block 201c is away from the fixing clamp 201b. At this time, under the pulling force of the first spring 201e, the fixing clamp 201b can be moved away from the lotion pump 103, thereby releasing the fixation of the lotion pump 103. At the same time, the air in the gas cylinder 203d is released through the deflation. The liquid is discharged into the air through the hole X, so that the air pressure in the gas cylinder 203d is reduced. Under the pulling force of the third spring 203g, the bellows 203e is contracted. At this time, the connecting sleeve 203f is separated from the top of the lotion pump 103. The air in the gas cylinder 203d is discharged at a faster speed through the delivery pipe 203h and the connecting sleeve 203f, so that the connecting sleeve 203f and the lotion pump 103 are completely separated. At this time, the lotion pump 103 can be removed from the support seat 102b.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
