Description

Technical Field

[0001] This utility model belongs to the field of valve body technology, specifically relating to a drain valve with automatic liquid extraction function. Background Technology

[0002] Currently, some ovens on the market experience overheating during use, so a water tank is added for water storage and circulation for cooling. However, the water level in current market water tanks is low, and the existing structure cannot drain properly. Research shows that most drainage methods rely on gravity to drain water through pipes. A patent with publication number CN114593243A discloses a liquid-drawing one-way valve, comprising: a one-way valve body including a valve body with an inner cavity; a liquid-drawing connector connected to an assembly connector; a first ball seat installed inside the liquid-drawing connector; a sliding member movably disposed within the cavity; a liquid-drawing spring installed within the cavity to push the sliding member to seal the first ball seat; and a liquid-drawing push rod slidably installed between the liquid-drawing connector and the first ball seat. When the push rod moves the sliding member, the liquid-drawing spring is compressed, and the internal channel of the push rod connects to the cavity. Existing liquid-drawing one-way valves often require manual liquid drawing, resulting in low automation and a poor operator experience. Furthermore, the existing valve body lacks an inclination between the inlet and outlet water passages, resulting in slow drainage speed. Therefore, a drain valve with an automatic liquid extraction function needs to be designed to overcome these difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing a drain valve with an automatic liquid extraction function. This invention automatically controls the flow of water by cooperating with the inner sleeve assembly and the plastic-sealed coil assembly, and sets a guide slope in the main valve body to accelerate the flow of liquid.

[0004] The objective of this invention is achieved through the following technical solution: a drain valve with automatic liquid extraction function, comprising a main valve body, with an inlet channel and an outlet channel respectively provided on the left and right sides of the main valve body; the main valve body is provided with an inner sleeve assembly for controlling the conduction state of the inlet channel and the outlet channel, the inner sleeve assembly comprising an iron core and a rubber core; the outer layer of the inner sleeve assembly is provided with a plastic-sealed coil assembly, the iron core moving relative to the main valve body when the plastic-sealed coil assembly is energized; in the default state, the rubber core abuts against the inlet end of the outlet channel; the main valve body is provided with a guide slope, the guide slope being disposed between the inlet channel and the outlet channel.

[0005] Preferably, the inner sleeve assembly further includes a return spring and an inner sleeve body; the inner sleeve body is fixedly installed on the main valve body, and the inner sleeve body is provided with a return spring and an iron core, with a rubber core fixedly installed at the end of the iron core; a plastic-sealed coil assembly is sleeved on the outer layer of the inner sleeve assembly, and a positioning bracket for fixing the two is provided between the plastic-sealed coil assembly and the inner sleeve body.

[0006] Preferably, the reset spring is disposed between the inner wall of the iron core and the inner sleeve body; the end of the iron core away from the rubber core is provided with an annular step, one end of the reset spring abuts against the annular step, and the other end of the reset spring abuts against the inner sleeve body.

[0007] Preferably, the positioning bracket extends into the gap between the encapsulated coil assembly and the inner sleeve body; the top end face of the positioning bracket is fitted with the top end face of the encapsulated coil assembly, and the bottom of the positioning bracket is fixedly installed on the inner sleeve body.

[0008] By default, the encapsulated coil assembly is de-energized, with the rubber core resting against the inlet of the outlet channel, isolating the outlet and inlet channels and keeping the main valve body closed. When the encapsulated coil assembly is energized, the iron core is attracted, which in turn moves the rubber core away from the inlet of the outlet channel, opening the main valve body and allowing water to flow from the inlet channel to the outlet channel.

[0009] Preferably, a fastener for fixing the inner sleeve body and the main valve body is provided between the inner sleeve body and the main valve body, and a sealing body for sealing the two is also provided between the inner sleeve body and the main valve body.

[0010] Preferably, the main valve body has an annular groove, and the bottom of the inner sleeve body has an annular protrusion; the annular groove contains a sealing element body; when the inner sleeve body is installed on the main valve body, the annular protrusion presses against the sealing element body.

[0011] Preferably, the outer contour of the sealing element body is adapted to the outer contour of the annular groove; the thickness of the sealing element body is less than the depth of the annular groove.

[0012] By designing a sealing element body, a better seal is achieved between the main valve body and the inner sleeve body, preventing liquid leakage. Simultaneously, the interlocking annular groove and annular protrusion facilitate the positioning of the inner sleeve body, making the assembly of the inner sleeve assembly with the main valve body easier and less prone to errors.

[0013] Preferably, the inner sleeve body is provided with a plurality of evenly distributed limiting slots, and the bottom of the plastic-sealed coil assembly is provided with a plurality of evenly distributed limiting protrusions; the limiting protrusions are disposed in the limiting slots, and the outer contour of the limiting protrusions matches the outer contour of the limiting slots.

[0014] By using the limiting slot and the limiting protrusion in combination, the encapsulated coil assembly is more securely installed on the inner sleeve body, preventing the encapsulated coil assembly from rotating relative to the inner sleeve body.

[0015] Preferably, the outer diameter of the water inlet channel is smaller than that of the water outlet channel; the inlet end of the water outlet channel is higher than the outlet end of the water inlet channel, and the guide slope extends from the inlet end of the water outlet channel to the outlet end of the water inlet channel.

[0016] The main valve body's inlet channel is connected to the water box. When the sealed coil assembly is energized, the main valve body automatically opens, and the liquid in the water box automatically enters the inlet channel under the action of gravity. When the water flows through the guide slope, the guide slope guides the water flow, making the water flow faster, so the water in the water box can be discharged quickly.

[0017] Compared with existing technologies, this utility model has the following advantages: 1. The inner sleeve assembly and the plastic-sealed coil assembly cooperate with each other, which facilitates automatic control of the water circuit and thus facilitates switching of the on / off state of the main valve body. 2. By setting a guide slope in the main valve body, the liquid flow is accelerated, thereby allowing the water in the water box to be discharged quickly. 3. The dimensions of the inner sleeve assembly and the main valve body are mutually positioned and matched, making their assembly more convenient, quick, and error-free. Attached Figure Description

[0023] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0024] like Figures 1 to 4As shown, this embodiment discloses a drain valve with automatic liquid extraction function, including a main valve body 1, with an inlet channel 2 and an outlet channel 3 respectively on the left and right sides of the main valve body 1; the main valve body 1 is provided with an inner sleeve assembly 4 for controlling the conduction state of the inlet channel 2 and the outlet channel 3, the inner sleeve assembly 4 including an iron core 41 and a rubber core 42; the outer layer of the inner sleeve assembly 4 is provided with a plastic-sealed coil assembly 5, when the plastic-sealed coil assembly 5 is energized, the iron core 41 moves relative to the main valve body 1; in the default state, the rubber core 42 abuts against the inlet end of the outlet channel 3; the main valve body 1 is provided with a guide slope 6, the guide slope 6 is disposed between the inlet channel 2 and the outlet channel 3.

[0025] The inner sleeve assembly 4 further includes a return spring 43 and an inner sleeve body 44. The inner sleeve body 44 is fixedly installed on the main valve body 1. The inner sleeve body 44 contains a return spring 43 and an iron core 41. A rubber core 42 is fixedly installed at the end of the iron core 41. A plastic-encapsulated coil assembly 5 is sleeved on the outer layer of the inner sleeve assembly 4. A positioning bracket 7 for fixing the plastic-encapsulated coil assembly 5 and the inner sleeve body 44 is provided between them. The return spring 43 is disposed between the iron core 41 and the inner wall of the inner sleeve body 44. An annular step 8 is provided at the end of the iron core 41 away from the rubber core 42. One end of the return spring 43 abuts against the annular step 8, and the other end of the return spring 43 abuts against the inner sleeve body 44. The positioning bracket 7 extends into the gap between the plastic-encapsulated coil assembly 5 and the inner sleeve body 44. The top end face of the positioning bracket 7 is fitted with the top end face of the plastic-encapsulated coil assembly 5, and the bottom of the positioning bracket 7 is fixedly installed on the inner sleeve body 44.

[0026] Fasteners 9 for securing the inner sleeve body 44 and the main valve body 1 are provided between them. A sealing element body 10 for sealing the two is also provided between the inner sleeve body 44 and the main valve body 1. The main valve body 1 has an annular groove 11, and the bottom of the inner sleeve body 44 has an annular protrusion 45. The sealing element body 10 is located within the annular groove 11. When the inner sleeve body 44 is installed on the main valve body 1, the annular protrusion 45 presses against the sealing element body 10. The outer contour of the sealing element body 10 matches the outer contour of the annular groove 11; the thickness of the sealing element body 10 is less than the depth of the annular groove 11. The inner sleeve body 44 has several evenly distributed limiting grooves 12, and the bottom of the encapsulated coil assembly 5 has several evenly distributed limiting protrusions 13. The limiting protrusions 13 are located within the limiting grooves 12, and their outer contours match the outer contours of the limiting grooves 12. The outer diameter of the water inlet channel 2 is smaller than that of the water outlet channel 3; the inlet end of the water outlet channel 3 is higher than the outlet end of the water inlet channel 2, and the guide slope 6 extends from the inlet end of the water outlet channel 3 to the outlet end of the water inlet channel 2.

[0027] The specific operation process of this embodiment is as follows: In the default state, the encapsulated coil assembly 5 is in the de-energized state, so the rubber core 42 abuts against the inlet end of the water outlet channel 3, and the water outlet channel 3 and the water inlet channel 2 are isolated from each other, so the main valve body 1 is in the closed state; when the encapsulated coil assembly 5 is energized, the iron core 41 can be attracted, and then the iron core 41 will drive the rubber core 42 away from the inlet end of the water outlet channel 3, and the main valve body 1 will be in the open state, so the water can flow from the water inlet channel 2 to the water outlet channel 3.

[0028] By setting the sealing body 10, a better seal is achieved between the main valve body 1 and the inner sleeve body 44, preventing liquid leakage. Simultaneously, the annular groove 11 and annular protrusion 45 cooperate to facilitate the positioning of the inner sleeve body 44, making the assembly of the inner sleeve assembly 4 and the main valve body 1 easier and less prone to errors. The limiting slot 12 and limiting protrusion 13 cooperate to ensure a more secure installation of the encapsulated coil assembly 5 on the inner sleeve body 44, preventing rotation of the encapsulated coil assembly 5 relative to the inner sleeve body 44.

[0029] The main valve body 1 has a water inlet channel 2 connected to a water box. When the plastic-sealed coil assembly 5 is energized, the main valve body 1 opens automatically, and the liquid in the water box automatically enters the water inlet channel 2 under the action of gravity. When the water flows through the guide slope 6, the guide slope 6 guides the water flow, and the water flow speed is faster, so the water in the water box can be discharged quickly.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
