Description

Technical Field

[0001] This utility model relates to an integrated solenoid valve. Background Technology

[0002] With the development of society, toilets have been widely used in people's lives and have brought great convenience to people's lives. Existing toilets are equipped with various water flushing devices.

[0003] High-end toilets typically use solenoid valves to control water flow. These valves usually have one inlet pipe and two outlet pipes. Originally, the inlet and outlet pipes were all on the same plane, with the inlet pipe in the middle and the two outlet pipes on either side. For the water in the inlet pipe to flow into the outlet pipes, a horizontal channel is needed. However, this horizontal channel can prevent the valve body from being demolded. Therefore, the valve body needs to be assembled from multiple parts, or a T-joint can be manufactured first, and then the valve body can be formed using a secondary injection molding process. Summary of the Invention

[0004] This invention aims to overcome the problems in the prior art, so an integrated solenoid valve is designed with an integrally formed valve body, eliminating the need for a three-way valve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated solenoid valve, comprising a valve body, an inlet pipe and two outlet pipes disposed on the valve body, the two outlet pipes being positioned behind the inlet pipe, two chambers disposed on the top of the valve body, the top of the inlet pipe extending into the two chambers, each outlet pipe entering one of the chambers via a transverse pipe, a valve plate disposed at the end of the transverse pipe, a sealing cap disposed at one end of the valve body, the sealing cap sealing the chamber, a spring disposed within the chamber, the two ends of the spring contacting the valve plate and the sealing cap respectively. In this solenoid valve, the inlet and outlet pipes are arranged front-to-back, avoiding transverse channels, thus allowing the valve body to be directly integrally molded without the need for a tee fitting. Furthermore, this front-to-back arrangement reduces the transverse dimension of the valve body, making it suitable for applications with size constraints.

[0006] In a preferred embodiment of this utility model, the circumference of the valve plate is pressed tightly by the sealing cap.

[0007] In a preferred embodiment of this utility model, two electromagnetic control mechanisms are also included. A flow channel is provided at the back pressure chamber of the valve plate, and the outlet of the flow channel extends to the side of the valve body located below the chamber. A cavity is provided at the outlet, and a channel is provided within the cavity, connecting the cavity and the outlet pipe. An electromagnetic control mechanism is provided on the side of the valve body, and this electromagnetic control mechanism controls the opening and closing of the outlet. Placing the electromagnetic control mechanism in this position reduces the longitudinal dimension of the product. Furthermore, since the cavity is located below the chamber, which accommodates two outlet pipes and one inlet pipe and is the widest part of the product, while the lower part of the chamber only has one inlet pipe and is relatively narrow, placing the electromagnetic control mechanism in this position does not significantly increase the width of the product.

[0008] In a preferred embodiment of this utility model, fixed seats are provided on both sides of the cavity, and bolts are connected to the fixed seats after passing through the outer shell of the electromagnetic control mechanism.

[0009] In a preferred embodiment of this utility model, one end of the electromagnetic control mechanism is inserted into the cavity, and the portion of the electromagnetic control mechanism inserted into the cavity is sealed to the inner wall of the cavity.

[0010] Compared with existing technologies, the advantages of this invention are as follows: the inlet and outlet pipes are arranged front and back, avoiding the presence of transverse channels, thus allowing the valve body to be directly integrally molded without the need for a tee fitting. Furthermore, this front-back arrangement also reduces the transverse dimensions of the valve body, making it suitable for applications with size limitations. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: an integrated solenoid valve, comprising a valve body 1 and two electromagnetic control mechanisms 2, wherein the valve body 1 is provided with an inlet pipe 11 and two outlet pipes 12. The two outlet pipes 12 are located behind the inlet pipe 11.

[0020] Two chambers 13 are provided on the upper part of the valve body 1. The top of the water inlet pipe 11 passes through the two chambers 13. Each water outlet pipe 12 enters one of the chambers 13 through a horizontal pipe 121. A valve plate 3 is provided at the end of the horizontal pipe 121. A sealing cap 4 is provided at one end of the valve body 3. The sealing cap 4 seals the chamber 13. The circumference of the valve plate 3 is pressed tightly by the sealing cap 4.

[0021] A spring 5 is installed inside the chamber 13, with its two ends contacting the valve plate 3 and the sealing cover 4, respectively. In this type of solenoid valve, the inlet and outlet pipes are arranged front-to-back, avoiding lateral channels. Therefore, the valve body can be directly molded as a single piece without the need for a tee fitting. Furthermore, this front-to-back arrangement reduces the lateral dimensions of the valve body, making it suitable for applications with size constraints.

[0022] A flow channel 31 is provided in the back pressure chamber of the valve plate 3. The outlet 3a of the flow channel 31 extends to the side of the valve body 1, located below the chamber 13. A cavity 32 is provided at the outlet 3a. A channel 33 is provided inside the cavity 32, and the channel 33 connects the cavity 32 and the water outlet pipe 12. An electromagnetic control mechanism 2 is provided on the side of the valve body 1. The electromagnetic control mechanism 2 controls the opening and closing of the outlet 3a. Fixing seats 34 are provided on both sides of the cavity 32. Bolts pass through the housing of the electromagnetic control mechanism 2 and are connected to the fixing seats 34.

[0023] One end of the electromagnetic control mechanism 2 is inserted into the cavity 32, and the part of the electromagnetic control mechanism inserted into the cavity is sealed with the inner wall of the cavity.

[0024] Placing the electromagnetic control mechanism in this position reduces the product's longitudinal dimensions. Furthermore, since the electromagnetic control mechanism is located below the chamber, which is the widest part of the product to accommodate two outlet pipes and one inlet pipe, and the bottom of the chamber is relatively narrow with only one inlet pipe, placing the electromagnetic control mechanism in this position will not significantly increase the product's width.
