[0025] Example:

[0026] like Figures 1 to 4 As shown, this embodiment provides a novel solenoid valve, comprising:

[0027] The housing (1) has an inlet chamber (2) and an outlet chamber (3) defined within it. An inlet (21) and an outlet (31) are respectively provided on the housing (1), and the inlet (21) is connected to the inlet chamber (2) and the outlet (31) is connected to the outlet chamber (3).

[0028] The valve plug assembly (4) enables the inlet chamber (2) and the outlet chamber (3) to communicate with or disconnect from each other.

[0029] The first Venturi tube (5) is disposed on the water outlet end of the water outlet cavity (3), and the first Venturi tube (5) is connected to the water outlet (31) at the end away from the water outlet cavity (3) to increase the flow rate of the water.

[0030] And / or a second Venturi tube, which is disposed on the inlet end of the inlet chamber (2) and is connected to the inlet (21) at the end away from the inlet chamber (2) to increase the flow rate of the inlet water.

[0031] In this embodiment, an inlet chamber (2) and an outlet chamber (3) are defined within the housing (1). An inlet (21) communicating with the inlet chamber (2) is provided on the housing (1), and an outlet (31) communicating with the outlet chamber (3) is provided on the housing (1). The inlet (21) is connected to an external water supply, and the outlet (31) is connected to an external water point. The valve plug assembly (4) is used to make the inlet chamber (2) and the outlet chamber (3) mutually connected or disconnected, thereby allowing the external water supply to supply water to the external water point or to stop the external water supply to the external water point. One end of the inner tube (5) is connected to the outlet end of the outlet chamber (3), and the other end is connected to the outlet (31). When the water flows through the first venturi tube (5), the flow rate of the water is increased by the Venturi effect of the first venturi tube (5). Of course, a second venturi tube can also be connected to the inlet end of the inlet chamber (2). The second venturi tube is connected to the inlet (21) at the end away from the inlet chamber (2). When the water flows through the second venturi tube, the flow rate of the water is increased by the Venturi effect of the second venturi tube. Its structure is simple and can effectively increase the flow rate of the water when it flows through the solenoid valve.

[0032] Further, the first venturi tube (5) includes a first inlet section (51), a first contraction section (52), a first throat section (53), and a first diffuser section (54). The first inlet section (51) is connected at one end to the outlet end of the outlet chamber (3) and at the other end to the first contraction section (52), and the diameter of the first contraction section (52) gradually decreases along the outlet direction. The first contraction section (52) is connected to the first throat section (53) at the end away from the first inlet section (51). The first throat section (53) is connected to the first diffuser section (54) at the end away from the first contraction section (52). The first diffuser section (54) is connected to the outlet (31) at the end away from the first throat section (53), and the diameter of the first diffuser section (54) gradually increases along the outlet direction.

[0033] Preferably, the second venturi tube includes a second inlet section, a second contraction section, a second throat section, and a second diffuser section. One end of the second inlet section is connected to the water inlet (21), and the other end is connected to the second contraction section, with the diameter of the second contraction section gradually decreasing along the water inlet direction. The second contraction section is connected to the second throat section at the end away from the second inlet section. The second throat section is connected to the second diffuser section at the end away from the second contraction section. The second diffuser section is connected to the water inlet end of the water inlet chamber (2) at the end away from the second throat section, with the diameter of the second diffuser section gradually increasing along the water inlet direction.

[0034] Specifically, the valve plug assembly (4) includes a spring (41), a valve stem (42), and a valve plug (43). A mounting cavity with one end open is defined within the housing (1). One end of the spring (41) abuts against the closed end of the mounting cavity, and the other end abuts against the valve stem (42). The valve plug (43) is disposed on the end of the valve stem (42) away from the spring (41). The valve plug (43) is movably disposed on the inlet end of the outlet chamber (3) so that the inlet chamber (2) and the outlet chamber (3) are either connected or disconnected.

[0035] Preferably, a cavity is defined within the housing (1), and a protruding plate (11) is provided upwardly within the cavity to divide the cavity into the water inlet cavity (2) and the water outlet cavity (3). The water inlet cavity (2) is located outside the water outlet cavity (3), and the valve plug (43) abuts against the protruding plate (11) to allow the water inlet cavity (2) and the water outlet cavity (3) to communicate with or be isolated from each other.

[0036] Specifically, a boss is provided on the closed end of the mounting cavity, and the spring (41) is sleeved on the outside of the boss at the end away from the valve stem (42).

[0037] In this embodiment, external fluid enters the inlet chamber (2) after passing through the inlet (21) and the second Venturi tube in sequence. Since the second Venturi tube adopts a Venturi structure, it is composed of a second inlet section, a second contraction section, a second throat section and a second diffuser section in sequence. The second inlet section is cylindrical, the second contraction section is conical, the second throat section is cylindrical and the second diffuser section is conical. According to Bernoulli's theorem, when the fluid flows through the second throat section of the second Venturi tube, the flow velocity will increase, thus increasing the inlet flow velocity.

[0038] In this embodiment, a cavity is defined inside the housing (1), and a protruding plate (11) is provided upward in the cavity to divide the cavity into the water inlet cavity (2) and the water outlet cavity (3). The water inlet cavity (2) is located outside the water outlet cavity (3). The valve plug (43) is movably disposed on the water inlet end of the water outlet cavity (3). The valve plug (43) is driven to move up and down by the valve stem (42), thereby causing the valve plug (43) to abut against the protruding plate (11) to isolate the water inlet cavity (2) and the water outlet cavity (3) from each other, or to move the valve plug (43) away from the protruding plate (11) to make the water inlet cavity (2) and the water outlet cavity (3) communicate with each other.

[0039] When the inlet chamber (2) and the outlet chamber (3) are connected to each other, the fluid in the inlet chamber (2) passes through the outlet chamber (3), the first Venturi tube (5), and the outlet (31) in sequence and is output to the water point. Since the structure of the first Venturi tube (5) adopts the Venturi structure, it is composed of the first inlet section (51), the first contraction section (52), the first throat section (53) and the first diffuser section (54) in sequence. The first inlet section (51) is cylindrical, the first contraction section (52) is conical, the first throat section (53) is cylindrical, and the first diffuser section (54) is conical. According to Bernoulli's theorem, when the fluid flows through the first throat section (53) of the first Venturi tube (5), the flow rate will increase, thus increasing the flow rate of the water outlet.

[0040] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
