Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

The drive assembly 10 has a drive end and a flow diversion chamber 11, part of the flow diversion chamber 11 is arranged on the drive end, and the drive assembly 10 also has a speed reduction mechanism 12, which is connected to the flow diversion chamber 11. The valve body 20 has a connecting chamber 21. The valve core assembly 30 is rotatably arranged in the connecting chamber 21, and the valve core assembly 30 has a circulation channel 31, which is used for fluid circulation, and the valve core assembly 30 also has a driving shaft 32, which is connected to the drive assembly 10 by driving, and the driving shaft 32 has a connecting hole 321 arranged through, one end of the connecting hole 321 is connected to the flow diversion chamber 11, and the other end of the connecting hole 321 is connected to the circulation channel 31, and a filter structure 40 is arranged at the connecting hole 321.

[0030] By applying the technical solution of the utility model, a low-temperature refrigerant can be introduced into the circulation channel 31 to form a low-temperature refrigerant flow path. The connecting hole 321 arranged on the driving shaft 32 can guide the low-temperature refrigerant in the circulation channel 31 into the guide cavity 11, so as to cool the driving component 10 by the refrigerant with a lower temperature, thereby reducing the magnetic loss of the driving component 10. By arranging a filtering structure 40 at the connecting hole 321, solid impurities in the refrigerant can be filtered out to prevent the solid impurities from entering the guide cavity 11 and affecting the transmission of the reduction mechanism 12, thereby preventing the reduction mechanism 12 from being affected by the solid impurities and getting stuck, thereby ensuring the service life and stability of the multi-way valve.

[0031] Specifically in the present application, the reduction mechanism 12 can be configured in the form of a planetary gear set to increase the torque of the drive assembly 10 and output the increased torque to the valve core assembly 30, thereby enabling rapid rotation of the valve core assembly 30 and thus achieving rapid switching of the cooling and heating modes of the multi-way valve.

[0032] Specifically, the valve core assembly 30 further includes a valve core body 33, one end of the drive shaft 32 away from the drive assembly 10 is connected to the valve core body 33, and the filter structure 40 is arranged on the side of the connecting hole 321 close to the valve core body 33. During the long-term use of the multi-way valve, solid impurities in the refrigerant will be filtered by the filter structure 40 and deposited on the filter structure 40. Through the above arrangement, a large amount of solid impurities can be prevented from being deposited inside the connecting hole 321, affecting the circulation of the refrigerant in the connecting hole 321, thereby ensuring the flow guiding effect of the connecting hole 321.

[0033] In the present application, the filter structure 40 includes a filter screen 41 and a fixing member, and the fixing member is used to limit the filter screen 41 in the communication hole 321. By setting the fixing member to limit the displacement of the filter screen 41, the filter screen 41 can be prevented from falling off due to the impact of the fluid or external shaking, thereby ensuring the stability of the filter screen 41 when in use.

[0034] refer to Figure 2 and Figure 3As shown, the communication hole 321 has a stepped installation section 3211 and a limiting section 3212, the installation section 3211 and the limiting section 3212 are connected to each other, the inner diameter of the installation section 3211 is smaller than the inner diameter of the limiting section 3212, the filter 41 is arranged in the installation section 3211, and the fixing member includes a gasket 42, the gasket 42 is arranged in the limiting section 3212, and the inner diameter of the gasket 42 is smaller than the diameter of the filter 41, so as to limit the filter 41 in the communication hole 321. In the present application, by setting the installation section 3211 and the limiting section 3212 in the form of stepped sections, the gasket 42 can be limited by the stepped surface formed between the installation section 3211 and the limiting section 3212, so as to ensure that the gasket 42 can be installed in place. The gasket 42 can limit the filter screen 41 to prevent the filter screen 41 from being affected by gravity after being impacted and falling off from the installation section 3211 into the circulation channel 31, thereby ensuring the stability of the valve core assembly 30 during use.

[0035] Furthermore, the communication hole 321 also has a flow section 3213, which is arranged on a side of the installation section 3211 away from the limiting section 3212, and the inner diameter of the flow section 3213 is smaller than the diameter of the filter 41, so as to limit the displacement of the filter 41 toward the flow section 3213. Through the above arrangement, the flow section 3213 and the installation section 3211 also form a step structure, which can prevent the filter 41 from being impacted by the refrigerant and moving in the direction of the guide cavity 11 with the movement of the refrigerant, and further improve the stability of the filter 41 installed in the communication hole 321.

At the same time, after the filter structure 40 is clogged with dirt, the fixing part can be taken out, and then the filter structure 40 can be taken out to clean the filter, thereby improving the maintenance performance of the valve core assembly 30.

[0037] In other feasible embodiments of the present application, the fixing piece may be riveted into the connecting hole 321 , or the fixing piece may be welded to the driving shaft 32 , so as to further enhance the stability of the connection between the fixing piece and the driving shaft 32 .

[0038] In a specific embodiment of the present application, the filter screen 41 is press-fitted in the communicating hole 321. Through the above arrangement, the stability of the filter screen 41 in the communicating hole 321 can be ensured, and the filter screen 41 is prevented from being deflected in the communicating hole 321 due to uneven impact of the fluid, resulting in a gap between the side wall of the filter screen 41 and the inner wall of the communicating hole 321, so that part of the fluid is not filtered by the filter screen 41 and directly passes into the guide cavity 11, thereby ensuring the performance of the filter structure 40.

[0039] In another specific embodiment of the present application, the fixing member and the filter screen 41 are both press-fitted into the communicating hole 321 by interference fit, thereby further improving the stability of the filter screen 41 and the fixing member installed in the communicating hole 321 .

The volume of the valve core assembly 30 is small, and the diameter of the connecting hole 321 is also small. Through the above arrangement, the closed end of the cylindrical filter screen 41 can increase the filtering area of ​​the filter screen 41 compared with the traditional flat filter screen, thereby improving the filtering effect of the filter screen 41.

[0041] Specifically in the present application, the valve body 20 further includes an inlet and outlet 22 and a communication port 23. There are multiple communication ports 23, which are arranged on the valve body 20 in annular intervals, and the multiple communication ports 23 are all connected to the communication cavity 21. One end of the circulation channel 31 is located on the rotation axis of the valve core assembly 30 and is connected to the inlet and outlet 22, and the other end of the circulation channel 31 can be selectively connected to the communication port 23. Through the above arrangement, when the valve core assembly 30 rotates in the communication cavity 21, the circulation channel 31 can be selectively connected to one of the multiple communication ports 23 to achieve the switching of the multi-way valve flow channel.

[0042] In the present application, the valve core assembly 30 also includes a valve core seat 34, which is arranged on the side of the valve core body 33 away from the drive shaft 32. The drive shaft 32, the valve core body 33 and the valve core seat 34 are arranged independently of each other. The valve core seat 34 has a first flow channel, and the valve core body 33 has a second flow channel. The first flow channel and the first end of the second flow channel are connected to each other, and the end of the first flow channel away from the second flow channel is used to communicate with the inlet and outlet 22 of the valve body 20 assembly, and the second end of the second flow channel is used to communicate with the connecting port 23 of the valve body 20. Through the above-mentioned arrangement, the drive shaft 32, the valve core body 33 and the valve core seat 34 are arranged independently of each other, which can facilitate the independent processing of the drive shaft 32, the valve core body 33 and the valve core seat 34 and reduce the processing difficulty; at the same time, it can also facilitate the installation of the filter structure 40. Before assembling the drive shaft 32, the valve core body 33 and the valve core seat 34, the installation and coordination of the filter structure 40 and the drive shaft 32 can be completed first to ensure that the filter structure 40 is installed in place and improve the assembly efficiency of the valve core assembly 30.

[0043] Specifically, a mounting hole is provided on the valve core body 33, the drive shaft 32 is inserted into the mounting hole, and the drive shaft 32 is welded to the valve core body 33. Through the above arrangement, the drive shaft 32 can be reliably fixed to the valve core body 33, ensuring the stability of the connection between the drive shaft 32 and the valve core body 33, and at the same time, the refrigerant fluid can be prevented from leaking from the mounting hole, thereby ensuring the airtightness of the valve core assembly and reducing the possibility of refrigerant fluid leakage, thereby ensuring the use effect of the valve core assembly.
