Description

Technical Field

[0001] This utility model relates to an improved solenoid valve with an improved valve body structure, classified as F16K11 / 24 by IPC. Background Technology

[0002] Existing electromagnetic pumps include a stator assembly and a valve body mounted on a water-proof sleeve of the stator assembly. The valve body typically has an inlet pipe and an outlet pipe. To prevent the external water pipe from detaching from the outlet pipe, a retaining spring is usually added to the outer surface of the external water pipe during installation to lock it securely to the outlet pipe. However, because the retaining spring is tightly pressed against the external water pipe, the external water pipe is easily flattened and deformed. When the external water pipe needs to be pulled out and disassembled, it is prone to cracking and damage, affecting subsequent use. Therefore, there is a need for improvement.

[0003] For terms and knowledge, unless otherwise specified in this manual, please refer to the "IEC Dictionary of Electrical and Electronic Standards Terminology" (China Standards Press, 1st edition, 1992), "Electrical Manufacturing Technology" (Mechanical Industry Press, 1st edition, 1982), "Mechanical Engineering Handbook" and "Electrical Engineering Handbook" (Mechanical Industry Press, 1st edition, 1978 and 2nd edition, 1997), as well as the national standard GB / T21465-2008 "Valve Terminology" and the light industry standard QB / T1291 "Solenoid Valves for Automatic Washing Machines".

[0008] Furthermore, there is a gap between the first mounting arm, the second mounting arm, and the connecting part and the outer surface of the water outlet pipe.

[0009] Furthermore, the inner side of the connector is provided with an undercut, which gradually increases in distance from the surface facing the axis of the water outlet pipe to the axis of the water outlet pipe as it moves away from the outlet pipe.

Detailed Implementation

[0019] Figure 1 and Figure 2 This utility model discloses an improved solenoid valve with an improved valve body structure. The solenoid valve includes a stator assembly 100, a spring 210 and a movable iron core 220 mounted on the stator assembly 100, a valve body 300 covering the stator assembly 100, and an opening and closing assembly 400 disposed in the working space enclosed by the valve body 300 and the stator assembly 100. The stator assembly 100 includes a coil assembly 120 and a water-proof sleeve 110 fixed on the coil assembly 120. The spring 210 and the movable iron core 220 are installed in the hollow cavity of the water-proof sleeve 110. The opening and closing assembly 400 includes a diaphragm plate 410 and a diaphragm 420 mounted on the diaphragm plate. After assembly, the opening and closing assembly 400 is disposed in the space enclosed by the stator assembly 100 and the valve body 300. The improvement of this utility model is the modification of the valve body 300. Other parts have the same structure as the prior art (see prior patent CN114110238B), and will not be described in detail here.

[0020] See Figure 1 The valve body 300 of this utility model includes a cap-shaped main body 350, an inlet pipe 310 and an outlet pipe 320 respectively connected to the main body 350. To reduce the installation process with external water pipes and avoid damage to the external water pipes after assembly, the outer surface of the outlet pipe 320 of this utility model is provided with an integrally injection-molded mounting bracket 330 for clamping with external water pipes. See [link to original text] Figure 2 When the solenoid valve of this utility model is installed with the external water pipe 500, after the external water pipe 500 is inserted into the outlet pipe 320, its mounting bracket 330 will clamp the external water pipe 500 onto the valve body 300, so as to prevent the external water pipe 500 from being crushed after assembly and improve the stability of the connection between the solenoid valve and the external water pipe.

[0021] See Figures 1 to 4The mounting bracket 330 of the solenoid valve of this utility model includes a first fixing part 336 and a second fixing part 337 protruding outward from the outer surface of the outlet pipe 320 near the valve body; a strip-shaped first mounting arm 331 extending from the first fixing part 336 toward the pipe opening; a long strip-shaped second mounting arm 332 extending from the second fixing part 337 toward the pipe opening; and an arc-shaped connecting part 333 connecting the first mounting arm 331 and the second mounting arm 332. The connecting part 333 has a notch 334 axially near the outlet pipe 320. (See...) Figure 2 The external water pipe 500 of this utility model has a water pipe protrusion 510 protruding outward on its radial outer surface. During installation, the external water pipe 500 is inserted into the water inlet pipe 320 installed in the valve body 300, and its water pipe protrusion engages with the notch 334 in the valve body 200. This design facilitates the disassembly and installation of the external water pipe, improving the ease of use of the solenoid valve.

[0022] Furthermore, see Figure 2 The valve body 300 of this invention has an inverted buckle 335 on its inner side of the connecting portion 330. This inverted buckle 335 gradually increases in distance from its surface facing the axis of the outlet pipe 320 towards the outlet pipe 320. This design facilitates the insertion of external water pipes and prevents the external water pipes from being crushed during insertion. Furthermore, see... Figure 4 In this utility model, the first mounting arm 331, the second mounting arm 332, and the connecting part 333 of the valve body 300 have gaps between them and the outer surface of the water outlet pipe 320. The above design allows the mounting bracket to be elastic, which facilitates the insertion and snap-fit ​​connection of the external water pipe.

[0023] Furthermore, see Figure 1 and Figure 2 To increase the contact area between the valve body 300 and the external water pipe 500 and to prevent the external water pipe 500 from being excessively inserted into the valve body and causing damage to the opening and closing components, the outlet pipe 320 of the valve body of this utility model has a rib 340 that is radially protruding outward on the outer surface of the area near the pipe opening, which is opposite to the notch 334.

[0024] Furthermore, see Figure 3 In this invention, the first mounting arm 331 and the second mounting arm 332 of the valve body 300 of the solenoid valve protrude from the surfaces facing the stator assembly 100, forming several columnar first protrusions 381 and second protrusions 382. This design guides condensate to accumulate in the first protrusions 381 and the second protrusions 382, ​​preventing condensate from flowing into the stator assembly 100 and causing a short circuit, thus further improving the operational stability of the solenoid valve.

[0025] This utility model provides another embodiment of the solenoid valve, see Figure 5The difference between the solenoid valve in this embodiment and the solenoid valve described above lies in the improvement of the valve body. Other structures, such as the stator assembly and the opening / closing assembly, are the same as described above and will not be repeated here. The main body of the valve body 300 in this embodiment includes a cap-shaped first main body 351 and a second main body 352. Its outlet pipe includes a first outlet pipe 321 communicating with the first main body 351 and a second outlet pipe 322 communicating with the second main body 352. The elastic mounting bracket 330 includes a first mounting bracket 360 disposed on the first outlet pipe 321 and a second mounting bracket 370 disposed on the second outlet pipe 322. The inlet pipe 310 of the valve body 300 is connected to the first main body 351 and the second main body 352 respectively. The solenoid valve designed in the above way has a compact structure and can be easily connected to an external water pipe.

[0026] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
