Description

Electromagnetic coil and electromagnetic valve having the same

[0001] This application claims priority to the patent application filed with the State Intellectual Property Office of China on July 25, 2023, with application number 202321975262.0 and application name “Electromagnetic coil and solenoid valve having the same”. Technical Field

[0002] The present application relates to the technical field of solenoid valves, and in particular to an electromagnetic coil and a solenoid valve having the same. Background Art

[0003] Currently, in refrigeration equipment applications, fluid flow control is often performed through solenoid valves. The solenoid valves include a solenoid coil and a valve body. The valve body is driven by the solenoid coil to control the opening and closing of the valve body.

[0004] Conventional electromagnetic coils consist of a body, a covering, and a retaining member. The covering wraps around the outer surface of the body, and the electromagnetic coil is sleeved over a valve body sleeve. The retaining member is external to the covering and connected to the sleeve to restrict relative movement between the electromagnetic coil and the sleeve. However, the retaining member can become loose during use, causing the electromagnetic coil to move relative to the sleeve during operation, resulting in noise and even control failure during solenoid valve operation. Furthermore, a loose retaining member can cause water to seep into the connection between the retaining member and the covering, leading to a short circuit or even burning of the electromagnetic coil.

[0005] Application Contents

[0006] The present application provides an electromagnetic coil and an electromagnetic valve having the same, so as to solve the problem that the fixing parts in the prior art are prone to loosening.

[0007] According to one aspect of the present application, an electromagnetic coil is provided, which includes: a main body, a first mounting hole extending through the middle of the main body; a limiter, the limiter is located on one side of the main body, the limiter is arranged corresponding to the first mounting hole, and the limiter can be matched and connected with the valve body of the electromagnetic valve to fix the valve body in the first mounting hole; and a covering layer wrapped around the outer periphery of the main body and the limiter to fix the main body and the limiter.

[0008] The technical solution provided in this application allows the main body to be inserted into the valve body through the first mounting hole and limited in position by the stopper, thereby preventing the main body from moving. By providing a covering layer wrapped around the outer periphery of the main body and the stopper, the relative positions of the stopper, base, and main body can be further restricted, preventing the stopper from loosening during use and ensuring the overall structural stability of the electromagnetic coil. Furthermore, the covering layer further seals the electromagnetic coil, preventing water from entering the main body and causing the electromagnetic coil to burn, thereby improving the safety of the electromagnetic coil during use.

[0009] Furthermore, the stopper has an abutting end and a free end disposed opposite each other. The abutting end defines a receiving cavity that communicates with the first mounting hole. The abutting end abuts the body, while the free end abuts the inner wall of the covering layer. The receiving cavity is capable of accommodating the end of the valve body. This arrangement allows the stopper to restrict movement of the body, allowing the body to maintain its relative position to the valve seat, thereby improving the structural stability of the electromagnetic coil during operation.

[0010] Furthermore, the position-limiting member includes a latch having a connection port, a first end, and a second end disposed opposite each other. The connection port is disposed on an end surface of the first end, forming a receiving cavity, and the second end of the latch forms a free end. This arrangement allows the latch to limit the relative position of the main body relative to the valve body, preventing movement of the main body and ensuring the performance of the electromagnetic coil.

[0011] Furthermore, the position limiting member further comprises a washer having a second mounting hole, the washer being sleeved on the valve body through the second mounting hole, and the washer being located between the body and the card cover. Through the above arrangement, the washer can improve the sealing effect between the body and the card cover.

[0012] Furthermore, a plurality of first connecting posts are provided on the first end, and the plurality of first connecting posts are arranged at annular intervals along the outer circumference of the connection port. The gasket also includes a plurality of first connecting holes, which are provided on the end face of the gasket near the card cover. The plurality of first connecting holes are provided in a one-to-one correspondence with the plurality of first connecting posts. A plurality of second connecting posts are also provided on the end face of the gasket away from the first connecting posts, and the plurality of second connecting posts are arranged at intervals along the circumference of the gasket. The second connecting posts are plugged into the body. Through the above arrangement, the connection between the limiter and the body can be constrained, preventing circumferential rotation between the limiter and the body, thereby improving the tightness of the limiter's limiting connection.

[0013] Furthermore, a stopper is provided on the outer wall of the card cover, the outer diameter of which gradually increases from the card cover toward the main body. This arrangement enables the stopper to act as a stopper at the connection between the first end of the card cover and the gasket, or between the first end of the card cover and the main body, preventing water from entering the main body through the connection between the first connecting post, thereby improving the safety of the electromagnetic coil during use.

[0014] Furthermore, a limiting structure is provided on the outer surface of the limiting member facing the covering layer, and the limiting structure can cooperate with the covering layer to limit the position. Through the above arrangement, the covering layer can be tightly connected to the card cover through the limiting structure, ensuring the connection performance of the covering layer and the card cover.

[0015] Furthermore, the main body includes an inductor coil and a magnetic frame. The inductor coil is located within the magnetic frame. One end of the valve body passes through one side of the magnetic frame, through the inductor coil, and out the other side of the magnetic frame. The magnetic frame has a plurality of second connection holes on a side near the card cover. The plurality of second connection holes are arranged in a one-to-one correspondence with the plurality of second connection posts. Through this arrangement, the second connection holes can cooperate with the first connection posts of the card cover or the second connection posts of the gasket to limit the relative circumferential position of the limiter relative to the main body, prevent the limiter and the main body from rotating relative to each other, and ensure the overall structural stability of the electromagnetic coil.

[0016] According to another aspect of the present application, a solenoid valve is provided, which includes a valve body and the solenoid coil as described above, wherein the solenoid valve body is partially inserted into the first mounting hole of the solenoid coil and is cooperatively connected with the limit member of the solenoid coil.

[0017] Furthermore, the valve body includes a base and a support portion, one end of the support portion being connected to the base, and the other end of the support portion being inserted into the first mounting hole. Through this arrangement, the stopper can cooperate with the base and the support portion to secure the body to the valve body, allowing the body to maintain its relative position to the valve body and ensuring the structural stability of the electromagnetic coil during operation.

[0018] Furthermore, a clamping structure is provided between the support portion and the limiting member, which is used to limit the displacement of the limiting member relative to the support portion. Through the above arrangement, the limiting member can be loosened during use, thereby preventing abnormal movement of the body and improving the stability of the electromagnetic coil.

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] As shown in Figure 1, an embodiment of the present application provides an electromagnetic coil, which includes a body 10, a stopper, and a covering layer 30. The body 10 has a first mounting hole extending therethrough in the middle thereof. The stopper is located on one side of the body 10 and is disposed correspondingly to the first mounting hole. The stopper can be coupled to the valve body 20 of the solenoid valve to secure the valve body 20 within the first mounting hole. The covering layer 30 wraps around the outer periphery of the body 10 and the stopper to secure the body 10 and the stopper.

[0037] Using the technical solution provided in this application, the main body 10 is installed on the valve body 20 through the first mounting hole, and the position of the main body 10 is restricted by the stopper, which can prevent the main body 10 from moving relative to the valve body 20. By providing a coating 30 wrapped around the outer periphery of the main body 10 and the stopper, the relative position of the stopper, valve body 20, and main body 10 can be further restricted, preventing the stopper from loosening during use and ensuring the overall structural stability of the electromagnetic coil. At the same time, the coating 30 can also further seal the electromagnetic coil, preventing water from entering the main body 10 and causing the electromagnetic coil to burn, thereby improving the safety performance of the electromagnetic coil during use.

[0038] In this application, the electromagnetic coil body 10 and the retaining member are enclosed within the coating 30. When installing the solenoid valve, the electromagnetic coil and the valve body 20 need only be assembled. While in the technical solution mentioned in the background art, the user needs to separately install the fixing member on the sleeve. With the technical solution provided by this application, all components are pre-encapsulated within the coating 30, eliminating the need for the user to install components on the electromagnetic coil. This reduces the number of installation steps required and improves installation efficiency.

[0039] Specifically, the coating layer 30 may be made of a material with strong plasticity, high corrosion resistance and excellent mechanical strength to improve the coating and sealing properties of the coating layer 30. In a specific embodiment of the present application, the coating layer 30 is made of bulk molding compound.

[0040] In the present application, the stopper has an abutting end and a free end that are arranged relative to each other. The abutting end has a receiving cavity that communicates with the first mounting hole. The abutting end abuts the body 10, and the free end abuts the inner wall of the covering layer 30. The receiving cavity is capable of accommodating the end of the valve body. Through this arrangement, the abutting end of the stopper abuts the body 10, which can limit the movement of the body 10, allowing the body 10 to maintain its relative position with the valve body 20, thereby ensuring the structural stability of the electromagnetic coil during operation.

[0041] As shown in Figures 1 and 2, the retaining member includes a latch 50 having a connection port. The latch 50 has a first end and a second end disposed opposite each other. The connection port is disposed on the end surface of the first end, forming a receiving cavity. The second end of the latch 50 forms a free end. This arrangement positions the end of the support portion 22 distal from the base 21 within the receiving cavity of the latch 50. The first end of the latch 50 abuts against the body 10. In this embodiment, the latch 50 limits the relative position of the body 10 with respect to the support portion 22, preventing movement of the body 10 and ensuring the performance of the electromagnetic coil.

[0042] As shown in Figures 3 to 7, a plurality of first connecting columns 53 are provided on the first end, and the plurality of first connecting columns 53 are arranged at annular intervals along the outer periphery of the connecting port. The limiter also includes a gasket 60, and the gasket 60 has a second mounting hole 61. The gasket 60 is sleeved on the valve body 20 through the second mounting hole 61, and the gasket 60 is located between the main body 10 and the card cover 50. The gasket 60 also includes a plurality of first connecting holes 62, and the first connecting holes 62 are arranged on the end face of the gasket 60 close to the card cover 50. The plurality of first connecting holes 62 are arranged in a one-to-one correspondence with the plurality of first connecting columns 53. A plurality of second connecting columns 63 are also provided on the end face of the gasket 60 away from the first connecting columns 53. The plurality of second connecting columns 63 are arranged at circumferential intervals along the gasket 60, and the second connecting columns 63 are plugged into the main body 10.

[0043] Through the above-described configuration, the gasket 60 enables the cover 50 to adapt to longer valve bodies 20. When electromagnetic coils of different sizes need to be produced, the specific dimensions of the fit between the main body 10 and the valve body 20 can be adjusted through the gasket 60 to meet the needs of solenoid valves of different specifications. In this embodiment, the cover 50 and the gasket 60 together form a stopper. The gasket 60 can complement the size adjustment of the electromagnetic coil in actual production, ensuring that the stopper can abut against the main body 10, so that the stopper always functions to limit the movement of the main body 10. The multiple first connecting posts 53 provided on the cover 50 cooperate with the multiple first connecting holes 62 provided on the gasket 60 to limit the circumferential rotation between the cover 50 and the gasket 60. The second connecting posts 63 provided on the gasket 60 cooperate with the main body 10 to constrain the connection between the stopper and the main body 10, preventing circumferential rotation between the stopper and the main body 10, thereby improving the tightness of the stopper's limit connection. In this embodiment, the number of the first connection columns 53 and the first connection holes 62 is set to three, which can improve the connection performance while reducing the processing difficulty and saving production costs.

[0044] Among them, the first connecting column 53 and the second connecting column 63 can be coaxially arranged, or the first connecting column 53 and the second connecting column 63 can be staggered. In this embodiment, the first connecting column 53 and the second connecting column 63 correspond one to one, and the first connecting column 53 and the corresponding second connecting column 63 are coaxially arranged.

[0045] As shown in FIG4 , in the present application, a stopper 54 is provided on the outer wall of the card cover 50. The outer diameter of the stopper 54 gradually increases from the card cover 50 toward the main body 10. This configuration enables the stopper 54 to act as a stopper for the gasket 60 or the main body 10, preventing water from entering the main body 10 through the connection of the first connecting column 53 and causing the electromagnetic coil to burn, thereby improving the safety of the electromagnetic coil during use. Furthermore, the gradual increase in the outer diameter of the stopper 54 from the card cover 50 toward the main body 10 can also improve the adsorption performance of the coating layer 30 and enhance the sealing performance between the card cover 50 and the gasket 60, as well as between the card cover 50 and the main body 10.

[0046] As shown in Figure 6, in the present application, the gasket 60 has a sealing groove at one end facing the main body 10, and a sealing ring is arranged in the sealing groove. By setting the sealing ring, the sealing performance between the gasket 60 and the main body 10 can be further improved, reducing the possibility of water entering the main body 10 through the second connecting column 63 and the second connecting hole 121, thereby improving the safety performance of the electromagnetic coil during use.

[0047] In the present application, a limiting structure 52 is provided on the outer surface of the limiting member facing the covering layer 30, and the limiting structure 52 can cooperate with the covering layer 30 to limit the position. Through the above arrangement, the covering layer 30 can be tightly connected to the card cover 50 through the limiting structure 52, ensuring the connection performance of the covering layer 30 and the card cover 50.

[0048] Specifically, the limiting structure 52 includes a limiting groove and / or a convex rib. This arrangement allows the retaining structure 52 to be manufactured using the cover 50 itself, saving production costs and improving production efficiency. The limiting groove or convex rib can be annularly disposed at the end of the cover 50, and the annular limiting groove or annular rib can be coaxially disposed with the cover 50.

[0049] As shown in FIG8 , in the present application, the body 10 includes an inductor 11 and a magnetic frame 12. The inductor 11 is located within the magnetic frame 12. One end of the valve body 20 passes through one side of the magnetic frame 12, through the inductor 11, and out of the other side of the magnetic frame 12. The side of the magnetic frame 12 near the card cover 50 has a plurality of second connection holes 121, and the plurality of second connection holes 121 are arranged in a one-to-one correspondence with the plurality of second connection posts 63. Through the above arrangement, the magnetic frame 12 can sort out the magnetic field generated by the inductor 11 when it is working, thereby improving the utilization efficiency of the magnetic field. In addition, the side of the magnetic frame 12 near the card cover 50 has a plurality of second connection holes 121, which can cooperate with the first connection post 53 of the card cover 50, or cooperate with the second connection post 63 of the gasket, to limit the relative position of the limiter relative to the body 10 in the circumferential direction, prevent the limiter and the body 10 from rotating relative to each other, improve the connection performance between the limiter and the body 10, and ensure the overall structural stability of the electromagnetic coil. In this embodiment, the second connection hole 121 is plugged into the second connection post 63 , and the first connection post 53 is plugged into the first connection hole 62 .

[0050] The present application also provides a solenoid valve, which includes a valve body and the above-mentioned electromagnetic coil. The valve body 20 is partially inserted into the first mounting hole of the electromagnetic coil and is connected with the limiting member of the electromagnetic coil.

[0051] Specifically, the valve body 20 includes a base 21 and a support portion 22. One end of the support portion 22 is connected to the base 21, and the other end of the support portion 22 is inserted into the first mounting hole. Through this arrangement, the stopper can cooperate with the base 21 and the support portion 22 to secure the main body 10 to the valve body 20, allowing the main body 10 to maintain its relative position to the valve body 20 and ensuring the structural stability of the electromagnetic coil during operation.

[0052] Furthermore, a snap-fit ​​structure is provided between the limiter and the support portion 22, and the snap-fit ​​structure is used to limit the displacement of the limiter relative to the support portion 22. By providing the snap-fit ​​structure, the limiter can be prevented from loosening due to the movement of the solenoid valve body during operation, thereby ensuring the limiting effect of the limiter. In the present application, the limiter and the snap-fit ​​structure cooperate to form a reliable fixing structure, preventing the limiter from loosening during use, thereby preventing the body 10 from moving, and improving the stability of the electromagnetic coil.

[0053] As shown in FIG2 , in the present application, a first snap-fit ​​groove 221 is provided on the outer side wall of the support portion 22 near one end of the accommodating cavity, and a second snap-fit ​​groove 51 is provided on the inner side wall of the accommodating cavity. The second snap-fit ​​groove 51 is located between the card cover 50 and the gasket 60. The first snap-fit ​​groove 221 and the second snap-fit ​​groove 51 are correspondingly arranged to form a mounting groove. A snap ring 40 is provided in the mounting groove, and the snap ring 40 cooperates with the mounting groove to form a snap-fit ​​structure. Through the above arrangement, the snap ring 40 cooperates with the mounting groove to limit the relative position between the limiter and the support portion 22, ensuring the limiter's limiting effect on the body 10, and further ensuring the structural stability of the electromagnetic coil.
