Description

Technical Field

[0001] This utility model relates to the technical field of electric heating valve cores, and in particular to an electric heating valve core that increases the starting flow rate. Background Technology

[0002] To address the issue of low water pressure startup, the existing electric water faucet industry has adjusted the startup pressure to a lower level. This results in a lower startup flow rate and less water output, leading to a slower water flow. As a result, the water stays in the faucet for a longer time during heating, causing the heating time to increase. Consequently, the startup temperature rise may exceed the specified value, thus failing to meet safety standards. Utility Model Content

[0003] In view of the shortcomings and defects of the existing technology, an electric heating valve core that increases the start-up flow rate is provided. In order to achieve the purpose of increasing the outflow of water during startup, this utility model provides the following technical solution.

[0004] An electric heating valve core for increasing start-up flow includes a fixed ceramic plate and a moving ceramic plate, which are rotatably coupled together. The moving ceramic plate includes a flow passage cavity, and the fixed ceramic plate includes an inlet cavity and an outlet cavity. One end of the flow passage cavity extends toward the outlet cavity to form a first flow groove, and the other end of the flow passage cavity extends toward the outlet cavity to form a second flow groove. When the moving ceramic plate rotates in a first direction, the first flow groove and the second flow groove simultaneously communicate with the outlet cavity.

[0005] Compared with the prior art, this utility model has a second flow groove on one side of the flow cavity. When the electric water faucet is started, the second flow groove can increase the water output of the electric water faucet when the water pressure is low, preventing the electric water faucet from having a small flow rate when starting, causing heat to accumulate inside the electric water faucet and resulting in a high temperature inside the faucet. When the starting pressure is reduced, the starting flow rate can be increased, so that the starting temperature rise meets the safety requirements.

[0006] Furthermore, the opposite direction of the first direction is set as the second direction, the fixed ceramic plate is provided with a glue-through membrane cavity, the moving ceramic plate rotates in the first direction, the flow cavity and the glue-through membrane cavity remain in communication, the moving ceramic plate rotates in the second direction, the flow cavity and the glue-through membrane cavity remain disconnected.

[0007] Through the above improvements, a flow channel is provided on the fixed ceramic plate. When the moving ceramic plate rotates in the first direction, the flow channel and the flow channel remain connected. When the moving ceramic plate rotates in the second direction, the flow channel and the flow channel remain disconnected. Through the connection and disconnection of the flow channel, the water from the electric water faucet is heated.

[0008] Furthermore, when the moving ceramic plate rotates to a first angle in the first direction, the communication area between the first flow channel and the water outlet cavity increases, the communication area between the flow passage cavity and the water inlet cavity increases, and the communication area between the second flow channel and the water outlet cavity decreases; when the moving ceramic plate rotates to a second angle in the first direction, the communication area between the first flow channel and the water outlet cavity increases, the second flow channel is disconnected from the water outlet cavity, and the communication area between the flow passage cavity and the water inlet cavity increases.

[0009] With the above improvements, when the moving ceramic plate rotates to the first angle in the first direction, both the first and second flow channels are connected to the water outlet chamber, which increases the flow rate during startup and prevents excessive temperature rise during startup; when the moving ceramic plate rotates to the second angle in the first direction, the second flow channel is disconnected from the water outlet chamber, and the flow rate adjustment after the startup point does not increase, so as to ensure the temperature rise requirements of users during normal use.

[0010] Furthermore, the first flow channel is an inclined channel, and the depth of the first flow channel near the flow cavity is greater than the depth of the side away from the flow cavity.

[0011] With the above improvements, the first flow channel is an inclined channel, and the depth of the side of the first flow channel near the flow cavity is greater than the depth of the side away from the flow cavity, so that the water in the first flow channel can flow smoothly into the outlet cavity for use.

[0012] Furthermore, an inclined groove is provided in the water outlet cavity. The depth of the inclined groove on the side near the through-film cavity is less than the depth on the side near the water outlet cavity. When the moving ceramic plate rotates to the first angle in the first direction, the communication space between the first flow channel and the water outlet cavity increases.

[0013] Through the above improvements, an inclined groove is provided in the water outlet cavity of the fixed ceramic plate. When the moving ceramic plate rotates to the first angle in the first direction, the inclined groove increases the communication space between the first flow channel and the water outlet cavity, thereby increasing the flow rate during startup.

[0014] Furthermore, when the moving ceramic plate rotates in the second direction, the flow passage cavity and the water outlet cavity are always connected. When the moving ceramic plate rotates from the initial position to the third angle, the flow passage cavity and the water inlet cavity gradually become connected and the connection area gradually increases.

[0015] With the above improvements, when the moving ceramic plate rotates in the second direction, the flow passage and the outlet are always connected. When the moving ceramic plate rotates from the initial position to the third angle, the connection area between the flow passage and the inlet gradually increases, and the cold water output gradually increases.

[0016] Furthermore, a valve shaft is provided at the upper end of the moving ceramic plate, and the valve shaft drives the moving ceramic plate to rotate relative to the fixed ceramic plate.

[0017] Through the above improvements, a valve shaft is installed on the moving ceramic plate. The valve shaft drives the moving ceramic plate to rotate relative to the fixed ceramic plate, and the valve shaft can provide a power source for the moving ceramic plate.

[0018] Furthermore, a cover is provided on the outer side of the fixed ceramic plate, the moving ceramic plate, and the valve shaft. A valve seat is provided on the side of the fixed ceramic plate away from the moving ceramic plate. A snap groove is provided at the end of the cover near the valve seat. A buckle is provided on the side wall of the valve seat. The buckle is engaged with the snap groove.

[0019] Through the above improvements, a cover is provided on the outside of the fixed ceramic plate, the moving ceramic plate, and the valve shaft. A valve seat is provided on the side of the fixed ceramic plate away from the moving ceramic plate. A snap groove is provided on the cover, and a snap is provided on the side wall of the valve seat. The snap and the snap groove are engaged to fix the cover on the valve seat so that the cover can protect the valve shaft, the fixed ceramic plate, and the moving ceramic plate.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] like Figures 1 to 6 The electric heating valve core shown includes a fixed ceramic plate 1 and a moving ceramic plate 2, which are rotatably coupled together. The moving ceramic plate 2 includes a flow passage cavity 2.1, and the fixed ceramic plate 1 includes an inlet cavity 1.1 and an outlet cavity 1.2. One end of the flow passage cavity 2.1 extends toward the outlet cavity 1.2 to form a first flow groove 2.2, and the other end of the flow passage cavity 2.1 extends toward the outlet cavity 1.2 to form a second flow groove 2.3. When the moving ceramic plate 2 rotates in the first direction X, the first flow groove 2.2 and the second flow groove 2.3 simultaneously communicate with the outlet cavity 1.2, and the communication area between the first flow groove 2.2 and the outlet cavity 1.2 gradually increases, while the communication area between the second flow groove 2.3 and the outlet cavity 1.2 gradually decreases.

[0032] The first flow channel 2.2, the second flow channel 2.3 and the flow passage cavity 2.1 are integrated. The bottom surface of the first flow channel 2.2 is a slope. The depth of the side of the first flow channel 2.2 near the flow passage cavity 2.1 is greater than the depth of the side away from the flow passage cavity 2.1, so that the water in the first flow channel 2.2 can flow smoothly into the water outlet cavity 1.2 for use.

[0033] A valve shaft 6 is provided on the side of the moving ceramic plate 2 away from the fixed ceramic plate 1. The valve shaft 6 drives the moving ceramic plate 2 to rotate relative to the fixed ceramic plate 1, and the valve shaft 6 can provide a power source for the moving ceramic plate 2.

[0034] A cover 7 is provided on the outside of the fixed ceramic plate 1, the moving ceramic plate 2 and the valve shaft 6. A valve seat 8 is provided on the side of the fixed ceramic plate 1 away from the moving ceramic plate 2. A groove 7.1 is provided on the end of the cover 7 near the valve seat 8. A buckle 8.1 is provided on the side wall of the valve seat 8. The buckle 8.1 and the groove 7.1 are engaged to fix the cover 7 on the valve seat 8 so that the cover 7 can protect the valve shaft 6, the fixed ceramic plate 1 and the moving ceramic plate 2.

[0035] Example 1: When the moving ceramic plate 2 rotates from its initial position to the first angle 3 relative to the fixed ceramic plate 1 in the first direction X, the first flow groove 2.2 and the second flow groove 2.3 on the moving ceramic plate 2 are both connected to the water outlet cavity 1.2. During the rotation, the connection area between the flow passage cavity 2.1 and the water inlet cavity 1.1 increases, the connection area between the first flow groove 2.2 and the water outlet cavity 1.2 increases, and the connection area between the second flow groove 2.3 and the water outlet cavity 1.2 decreases. However, the overall connection area between the first flow groove 2.2 and the second flow groove 2.3 and the flow passage cavity 2.1 remains increased, which increases the water flow when the electric water faucet is started, preventing excessive temperature rise during startup.

[0036] As the moving ceramic plate 2 rotates from the first angle 3 to the second angle 4 in the first direction X, the second flow channel 2.3 is disconnected from the water outlet chamber 1.2, and the communication area between the first flow channel 2.2 and the flow passage chamber 2.1, as well as the communication area between the water inlet chamber 1.1 and the flow passage chamber 2.1, continuously increases. The water output also gradually increases with rotation to prevent a sudden increase in water output and to ensure the temperature rise requirement for normal use by the user.

[0037] Example 2: When the moving ceramic plate 2 rotates relative to the fixed ceramic plate 1 in the second direction Y, and as the moving ceramic plate 2 continues to rotate, from the initial position until it rotates to the third angle 5, the flow passage 2.1 is always connected to the water outlet 1.2, the connection area between the flow passage 2.1 and the water inlet 1.1 gradually increases, and when the moving ceramic plate 2 rotates in the second direction Y, the flow passage 2.1 and the membrane passage 1.3 are always disconnected, and the electric water faucet is not heated. At this time, cold water flows out of the electric water faucet, and the flow rate of cold water also increases with rotation.

[0038] Example 3: An inclined groove 1.21 is provided in the water outlet cavity 1.2 of the fixed ceramic plate 1. The depth of the inclined groove 1.21 near the adhesive membrane cavity 1.3 is less than the depth near the water outlet cavity 1.2. When the moving ceramic plate 2 rotates to the first angle 3 in the first direction X, the inclined groove 1.21 increases the communication space between the first flow channel 2.2 and the water outlet cavity 1.2, thereby increasing the flow rate during startup.

[0039] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope.
