Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and to an aerosol can valve testing device, and particularly to an aerosol can valve testing device with a simple structure and easy operation. Background Technology
[0002] An aerosol can is a complete pressurized packaging container consisting of a valve, a container, and contents (including the product, propellant, etc.). When the valve is opened, the contents are released at a predetermined pressure in a controlled manner. It features ease of use, good sealing, restrictions on the shape of the contents, and safe use. After filling, the aerosol can valve needs to be tested (test spray) to confirm product reliability. Currently, this is mainly done by manually pressing the valve. While this method can test reliability, it is cumbersome, has low automation, and is difficult to adapt to assembly line operations.
[0003] Therefore, developing a simple, easy-to-operate aerosol can valve testing device that can be adapted to assembly line operations is of great practical significance. Utility Model Content
[0004] Due to the aforementioned deficiencies in the existing technology, this utility model provides an aerosol can valve testing device that is simple in structure, easy to operate, and adaptable to assembly line operations, in order to solve the problems that aerosol can valve testing operations are relatively cumbersome, have a low degree of automation, and are difficult to adapt to assembly line operations.
[0005] To achieve the above objectives, the utility model provides the following technical solution:
[0006] An aerosol can valve testing device includes a fixed cylinder, a guide cylinder, a compression spring, a movable cylinder, a reflector, and a photoelectric sensor;
[0007] The bottom of the fixed cylinder extends radially outward with a lower fixing ring. The guide cylinder is installed on the fixed cylinder. The top of the movable cylinder is provided with an aerosol can valve insertion interface that communicates with the hollow part of the movable cylinder, and its bottom is opened with a movable cylinder guide hole that matches the guide cylinder. The side of the movable cylinder has two movable cylinder side openings that are arranged opposite to each other and communicate with the hollow part of the movable cylinder. The guide cylinder is inserted into the movable cylinder guide hole of the movable cylinder. The compression spring is sleeved outside the fixed cylinder and is located between the lower fixing ring and the movable cylinder. The reflector and the photoelectric sensor are fixedly connected to the movable cylinder through an external plate, and the reflector and the photoelectric sensor are respectively arranged on the outside of the two movable cylinder side openings.
[0008] The operation of testing aerosol can valves using an aerosol can valve testing device is as follows: Fix the lower fixing ring of the fixed cylinder. Insert the discharge pipe of the aerosol can valve, which is installed on the aerosol can, into the valve insertion port. At this time, the pressing surface of the aerosol can valve contacts the insertion port. Press down on the aerosol can valve, and it will open under pressure. The aerosol can material is sprayed out through the discharge pipe in an umbrella shape. The reflector and photoelectric sensor work together to detect the sprayed aerosol can material. The reflector transmits the photoelectric signal sprayed onto its side to the photoelectric sensor. The reflector design avoids the situation where the aerosol can material is sprayed all towards the reflector side, thus affecting the test. It also saves one photoelectric sensor, reducing costs and further ensuring the reliability of the test.
[0009] This utility model discloses an aerosol can valve testing device with a relatively simple structure and reasonable design. The hollow part of the movable cylinder provides a testing space for the material sprayed from the aerosol can valve. The two side openings of the movable cylinder on both sides of the testing space expose the testing space. The reflectors and photoelectric sensors set on both sides of the testing space can work together to detect the material in the testing space. The movable cylinder, guide cylinder and compression spring work together to realize rapid reciprocating operation, which simplifies the testing operation and has good application prospects.
[0010] As a preferred technical solution:
[0011] As described above, in an aerosol can valve testing device, the lower fixing ring has multiple fixing holes arranged in a circle, which can be used to fix the fixing cylinder.
[0012] In the aerosol can valve testing device described above, the fixing hole is a strip-shaped hole.
[0013] As described above, in an aerosol can valve testing device, the top of the fixed cylinder has a fixed cylinder guide cylinder through hole that matches the guide cylinder. One end of the guide cylinder extends out of the fixed cylinder guide cylinder through hole and the other end is limited by the fixed cylinder guide cylinder through hole. A guide cylinder support is installed below the guide cylinder and the guide cylinder support is located inside the fixed cylinder to ensure that the guide cylinder will not fall off.
[0014] As described above, in an aerosol can valve testing device, the reflector is fixed to the movable cylinder via an outer reflector plate.
[0015] The photoelectric sensor is fixed to the movable cylinder via a photoelectric sensor external plate.
[0016] In the aerosol can valve testing device described above, both the reflector outer plate and the photoelectric sensor outer plate are fixed to the movable cylinder by bolts;
[0017] The reflector and its outer plate, and the photoelectric sensor and its outer plate are connected by bolts.
[0018] In the aerosol can valve testing device described above, both the reflector outer plate and the photoelectric sensor outer plate are L-shaped.
[0019] The above technical solution is only one feasible technical solution of this utility model. The protection scope of this utility model is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.
[0020] Compared with the prior art, the above-mentioned utility model has the following advantages or beneficial effects:
[0021] This utility model discloses an aerosol can valve testing device with a relatively simple structure and reasonable design. The hollow part of the movable cylinder provides a testing space for the material sprayed from the aerosol can valve.

A guide cylinder 10 is mounted on the fixed cylinder 3. A guide cylinder through hole matching the guide cylinder 10 is opened at the top of the fixed cylinder 3. One end of the guide cylinder 10 passes through the guide cylinder through hole, and the other end is limited by the guide cylinder through hole. A guide cylinder support 11 is installed below the guide cylinder 10 and is located inside the fixed cylinder 3. The top of the movable cylinder 5 has an aerosol can valve insertion interface 52 communicating with the hollow part 54 of the movable cylinder, and its bottom has a movable cylinder guide hole 53 matching the guide cylinder 10. Oppositely arranged and connected to the movable cylinder 5, the side of the movable cylinder 5 has... The hollow part 54 of the cylinder connects the two movable cylinder side openings 51.
