Description

Technical Field

[0001] This utility model relates to the technical field of automotive air conditioning, and in particular to a self-filtering and cleaning device for automotive air conditioning refrigerant charging equipment. Background Technology

[0002] With the continuous development of vehicle thermal management systems, the structure of the refrigerant side of the system is becoming increasingly complex, and the number of refrigerant-side components is also constantly increasing. Consequently, the cleanliness requirements for the thermal management system are constantly rising. Refrigerant charging equipment integrates system vacuuming and refrigerant charging functions. During the vacuuming process, foreign matter and impurities from the system and the environment are sucked into the equipment's piping. Impurities collected during the refrigerant charging process can easily backflow into the vehicle's air conditioning system, causing problems such as excessive impurities or poor sealing within the system. Current technology typically achieves cleanliness by completely disassembling the equipment and performing deep maintenance, purging and cleaning each component individually. However, in practical applications, it has been found that the complete disassembly and deep maintenance of the charging equipment is time-consuming and inefficient. Utility Model Content

[0003] In order to improve the cleaning efficiency of refrigerant charging equipment while reducing the residue of foreign objects inside the equipment, thereby improving the cleanliness of the entire vehicle air conditioning system, this application provides a self-filtering cleaning device for automotive air conditioning refrigerant charging equipment.

[0004] This application provides a self-filtering and cleaning device for automotive air conditioning refrigerant charging equipment, which adopts the following technical solution: A self-filtering and cleaning device for automotive air conditioning refrigerant charging equipment is installed on the pipeline of the refrigerant charging equipment. It includes a Y-type filter and an on / off hydraulic quick-connect coupling. The Y-type filter includes a first connection port, a second connection port, and a service port. The on / off hydraulic quick-connect coupling includes a male and a female connector that interlock. The pipeline of the refrigerant charging equipment includes a first pipeline and a second pipeline. The first pipeline is connected to and communicates with the Y-type filter through the first connection port, and the second pipeline is connected to and communicates with the Y-type filter through the second connection port. The male connector is connected to and communicates with the Y-type filter through the service port. A valve is provided at the end of the male connector away from the Y-type filter, and the opening and closing of the valve is controlled by the interlocking of the female and male connectors.

[0005] By adopting the above technical solution, during normal vacuuming and refrigerant charging of the charging equipment, the maintenance port of the Y-type filter is normally closed due to the valve setting on the male connector. When rapid cleaning of the pipeline is required, the female and male connectors of the openable hydraulic quick connector are quickly plugged in and connected. The other end of the female connector is connected to compressed air. The high-pressure air backflushes the impurities in the filter screen and the charging equipment pipeline and discharges them from the nozzle of the charging equipment, which achieves a rapid cleaning effect. After cleaning, the female connector only needs to be unplugged, and the charging equipment can be restored to normal use, realizing a quick switch between self-cleaning mode and daily charging mode.

[0006] Preferably, the inner walls of the first and second connection ports are provided with internal threads, the outer walls of the first and second pipelines are provided with external threads that mate with the internal threads, the outer wall of the maintenance port is provided with external threads, and the male end is provided with internal threads that mate with the external threads.

[0007] By adopting the above technical solution, the Y-type filter is sealed to the pipeline and male connector of the filling equipment.

[0008] Preferably, the opening and closing hydraulic quick coupling is made of brass.

[0009] By adopting the above technical solution, the copper contains a high proportion of copper and zinc, which makes the resulting open-close hydraulic quick coupling have good corrosion resistance and is inexpensive, thus controlling production costs.

[0010] Preferably, the Y-type filter includes a filter screen located at the end of the Y-type filter where a maintenance port is provided.

[0011] By adopting the above technical solution, the filter screen is used to intercept impurities in the vehicle's air conditioning system.

[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. The Y-type filter is connected in the pipeline of the filling equipment, and the male of the openable hydraulic quick coupling is threaded to the maintenance port of the Y-type filter, which has good sealing performance and does not affect the normal vacuuming and refrigerant filling of the equipment. 2. By inserting and removing the female and male heads of the openable and closable hydraulic quick-connect coupling, the self-cleaning mode and daily filling mode of the filling equipment system can be quickly switched, making it convenient to use.

Figure 1 and Figure 2 It includes a Y-type filter 1 and an on / off hydraulic quick coupling 2. The Y-type filter 1 is made of stainless steel, while the on / off hydraulic quick coupling 2 is made of brass. Brass contains a high proportion of copper and zinc, which makes the on / off hydraulic quick coupling 2 have good corrosion resistance and is inexpensive, thus controlling production costs.

[0018] Reference Figure 1 and Figure 2 The Y-type filter 1 includes a first connection port 11, a second connection port 12, and a maintenance port 13. The piping of the refrigerant charging equipment includes a first pipe 111 and a second pipe 121. The first pipe 111 is connected to the Y-type filter 1 through the first connection port 11 and is in communication with it. The second pipe 121 is connected to the Y-type filter 1 through the second connection port 12 and is in communication with it. The inner walls of the first connection port 11 and the second connection port 12 are provided with internal threads. The outer walls of the first pipe 111 and the second pipe 121 are provided with external threads that mate with the internal threads, so that the Y-type filter 1 is sealed to the piping of the charging equipment.

[0019] Reference Figure 1 and Figure 2 The openable / closeable hydraulic quick connector 2 includes a male connector 21 and a female connector 22 that fit together. The male connector 21 is connected to and communicates with the Y-type filter 1 through a service port 13. The outer wall of the service port 13 is provided with an external service thread, and the male connector 21 is provided with an internal service thread that mates with the external service thread, so that the male connector 21 and the Y-type filter 1 are sealed together. A valve is provided at the end of the male connector 21 away from the Y-type filter 1, and the opening and closing of the valve is controlled by the insertion and engagement of the female connector 22 with the male connector 21.

[0021] The implementation principle of the self-filtering and cleaning device for automotive air conditioning refrigerant charging equipment in this embodiment is as follows: A Y-type filter 1 is installed in the charging equipment pipeline, and the maintenance port 13 of the Y-type filter 1 is threadedly connected to the male connector 21 of the open-close hydraulic quick connector 2. During normal vacuuming and refrigerant charging of the charging equipment, the maintenance port 13 of the Y-type filter 1 is normally closed due to the valve on the male connector 21. When rapid pipeline cleaning is required, the female connector 22 of the open-close hydraulic quick connector 2 is quickly plugged into the male connector 21. The other end of the female connector 22 is connected to compressed air. The high-pressure air backflushes the impurities in the filter screen 14 and the charging equipment pipeline and discharges them from the nozzle of the charging equipment, thus achieving rapid cleaning. After cleaning, simply disconnect the female connector 22, and the charging equipment can resume normal use, realizing a quick switch between self-cleaning mode and daily charging mode.
