Description

Technical Field

[0001] This utility model relates to the technical field of toilet control valves, specifically a toilet control valve that is compatible with both flushing and air extraction. Background Technology

[0002] With the development of smart home technology, smart toilets with dual functions of flushing and odor extraction have become mainstream products in the market. These toilets use water inlet control to achieve the flushing and cleaning function, and use odor extraction control to remove odorous gases generated during use to improve user comfort.

[0003] Traditional smart toilets typically employ a separate control scheme for water inlet and air extraction functions. This means that a dedicated water inlet control valve controls the flow and volume of flushing water, while a separate air extraction control valve controls the opening and closing of the air extraction channel and the adjustment of negative pressure.

[0004] However, using two independent control valves in a toilet significantly increases the number of parts and assembly volume, severely occupying the limited installation space inside the toilet and hindering the development of toilets towards compactness and thinness. Utility Model Content

[0005] To address the aforementioned shortcomings, this utility model proposes a toilet control valve that is compatible with both flushing and air extraction. This application integrates the water inlet port, air extraction port, and common port into the switching chamber of the same valve body. By using a power component to drive the baffle to swing, selective blocking and switching between the water inlet channel and the air extraction channel can be achieved. There is no need to set up separate switching pipelines, valves, or linkage mechanisms, which significantly reduces the number of parts and assembly processes, simplifies the overall structural complexity, and solves the problem that traditional toilets with air extraction functions require two sets of independent control valves.

[0006] To achieve this objective, the present invention adopts the following technical solution: A flushing and air-suction compatible toilet control valve includes a valve body, a power component, and an air-suction component. The valve body has a hollow section forming a switching cavity. The valve body is surrounded by a water inlet port, an air-suction port, and a common port. The switching cavity is connected to the water inlet port, the air-suction port, and the common port, respectively. The inner wall of the valve body is rotatably provided with a baffle, and the output end of the power component is fixedly connected to the baffle. The power component is used to swing the baffle, and the swing of the baffle is used to block the water inlet port or the air intake port. The air inlet of the suction component is connected to the suction port, and the suction component is used to extract gas from the switching chamber and the suction port.

[0007] The water inlet port is vertically disposed at the bottom of the valve body, the common port is obliquely disposed at the top of the valve body, and the air intake port is obliquely disposed between the water inlet port and the common port, forming a triangular structure with the water inlet port, the air intake port and the common port; The air intake port is inclined from top to bottom toward the inside of the switching cavity, and the common port is inclined from top to bottom toward the outside of the switching cavity.

[0008] The valve body also includes a flushing port, which is connected to the switching chamber. The flushing port is inclined between the water inlet port and the common port. The water inlet port and the air intake port are located on the left and right sides of the switching chamber, respectively. The flushing port is inclined from top to bottom towards the bottom of the switching chamber.

[0009] The diameter of each air intake port is smaller than the diameter of the water inlet port, the common port, and the flushing port.

[0010] The inner wall of the valve body is provided with a baffle plate, which is inclinedly disposed between the flush port and the inlet port. The baffle plate is used to obliquely block the bottom of the flush port.

[0011] The extension direction of the flushing port forms an angle β with the extension direction of the water inlet port, and the angle β is 100-120°.

[0012] The baffle has an air intake shield on the side near the air intake port, and the air intake shield is adapted to the air intake port; the baffle has a water inlet shield on the side near the water inlet port, and the water inlet shield is adapted to the water inlet port.

[0013] The technical solution of this utility model can include the following beneficial effects: 1. By integrating the water inlet port, air intake port, and common port into the switching chamber of the same valve body, selective blocking and switching between the water inlet channel and the air intake channel can be achieved by using a power component to drive the baffle to swing. There is no need to set up separate switching pipelines, valves, or linkage mechanisms, which significantly reduces the number of parts and assembly processes, simplifies the overall structural complexity, and solves the problem that traditional toilets with air suction function need to use two sets of independent control valves.

[0014] 2. Under vacuum conditions, after the baffle blocks the water inlet port, some residual water may remain in the toilet bowl's wash ring, flush port, and switching chamber. The baffle is angled between the flush port and the water inlet port, forming a physical barrier that effectively prevents residual water from flowing towards the blocked water inlet port, thus preventing water from seeping into the water inlet port or adhering to the sealing surface under negative pressure.

[0020] The following is combined with Figures 1 to 4 This invention describes a flushing and air extraction compatible toilet control valve according to an embodiment of the present invention.

[0021] A toilet control valve compatible with flushing and air extraction includes a valve body 31, a power component 32, and an air suction component 33. The valve body 31 has a hollow interior forming a switching cavity. The valve body 31 is circumferentially provided with a water inlet port 301, an air suction port 302, and a common port 303. The switching cavity is connected to the water inlet port 301, the air suction port 302, and the common port 303, respectively. The inner wall of the valve body 31 is rotatably provided with a baffle 34. The output end of the power component 32 is fixedly connected to the baffle 34. The power component 32 is used to swing the baffle 34. The swing of the baffle 34 is used to block the water inlet port 301 or the air intake port 302. The air inlet of the suction component 33 is connected to the suction port 302, and the suction component 33 is used to extract gas from the switching chamber and the suction port 302.

[0022] It is worth noting that the air outlet of the suction component 33 is connected to the drain pipe of the toilet, the water inlet of the water inlet port 301 is connected to the water pump of the toilet, and the water outlet of the common port 303 is connected to the wash ring of the toilet.

[0023] When flushing, the drive unit drives the baffle 34 to rotate, causing the baffle 34 to block the air intake port 302. At this time, the water inlet port 301, the switching chamber and the common port 303 are connected to each other. Then the toilet's water pump is started, so that the water flows through the water inlet port 301, the switching chamber and the common port 303 in sequence, and then sprays outward from the toilet's wash ring, thus completing the flushing process.

[0024] During air intake, the power component 32 drives the baffle 34 to rotate, causing the baffle 34 to block the flushing port 304, thereby connecting the air intake port 302, the switching chamber, and the common port 303. Then, the air intake component 33 is activated, allowing the gas to flow from the water outlet of the washing ring through the common port 303, the switching chamber, and the air intake port 302 in sequence, and finally be discharged from the air outlet of the air intake component 33, thus completing the air intake process.

[0025] Therefore, this application integrates the water inlet port 301, the air intake port 302, and the common port 303 into the switching chamber of the same valve body 31. By using the power component 32 to drive the baffle 34 to swing, the selective blocking and switching of the water inlet channel and the air intake channel can be achieved. There is no need to set up separate switching pipelines, valves, or linkage mechanisms, which significantly reduces the number of parts and assembly processes, simplifies the overall structural complexity, and solves the problem that traditional toilets with air suction function need to use two sets of independent control valves 3.

[0026] The water inlet port 301 is vertically disposed at the bottom of the valve body 31, the common port 303 is obliquely disposed at the top of the valve body 31, and the air intake port 302 is obliquely disposed between the water inlet port 301 and the common port 303. The water inlet port 301, the air intake port 302 and the common port 303 form a triangular structure. The air intake port 302 is inclined from top to bottom toward the inside of the switching cavity, and the common port 303 is inclined from top to bottom toward the outside of the switching cavity.

[0027] The water inlet port 301 is vertically positioned, while the common port 303 is angled. This design allows water to flow vertically upwards into the switching chamber from the bottom, then naturally guides to the washing ring along the angle of the common port 303, forming a smooth upward flow path and significantly reducing energy loss caused by water flow deflection. During air extraction, the suction port 302 is angled downwards towards the inside of the switching chamber. This design allows airflow entering the switching chamber from the common port 303 to quickly converge at the suction port 302, reducing gas flow resistance and improving extraction efficiency.

[0028] The valve body 31 also includes a flushing port 304, which is connected to the switching chamber. The flushing port 304 is inclined between the water inlet port 301 and the common port 303. The water inlet port 301 and the air intake port 302 are located on the left and right sides of the switching chamber, respectively. The flushing port 304 is inclined from top to bottom towards the bottom of the switching chamber.

[0029] It is worth noting that the water outlet of flush port 304 is connected to the water inlet at the bottom of the toilet.

[0030] After the vertically input water flow enters the switching cavity through the inlet port 301, it can be naturally diverted along the inner walls of the two inclined ports. It can flow to the common port 303 and the flushing port 304 respectively without additional turning. The flow path transition is smooth, avoiding eddies and impact losses generated during diversion.

[0031] At this time, the water flow from the common port 303 is sprayed evenly along the wash ring, performing a full-range circular flush on the inner wall of the toilet to remove dirt attached to the side wall; the water flow from the flush port 304 flows directly from the bottom inlet to the drain outlet, forming a strong siphon or direct flush to quickly remove the dirt deposited at the bottom, achieving a coordinated cleaning mode of top circular flush and bottom direct flush.

[0032] The diameter of the air intake port 302 is smaller than the diameter of the water inlet port 301, the common port 303, and the flushing port 304.

[0033] Gas molecules are highly mobile and sensitive to resistance. The smaller diameter of the intake port 302 allows the negative pressure generated by the intake component 33 to be concentrated on the airflow channel, reducing negative pressure diffusion loss, increasing the airflow velocity per unit cross-sectional area, and ensuring that odorous gases quickly converge and are efficiently discharged.

[0034] The flushing operation needs to meet the requirements of large flow and high pressure. The larger diameter inlet port 301, common port 303 and flushing port 304 can reduce the water flow resistance, ensure sufficient total flow during dual flushing, avoid pressure attenuation due to insufficient flow channel cross section, and enable the water flow to achieve flushing and sewage discharge functions with strong kinetic energy.

[0035] The inner wall of the valve body 31 is provided with a baffle plate 35, which is inclinedly disposed between the flush port 304 and the inlet port 301. The baffle plate 35 is used to obliquely block the bottom of the flush port 304.

[0036] Under vacuum conditions, after the baffle 34 blocks the water inlet port 301, some residual water may remain in the toilet bowl, flush port 304, and switching chamber. The baffle 35 is inclinedly positioned between the flush port 304 and the water inlet port 301, forming a physical barrier that effectively prevents residual water from flowing towards the blocked water inlet port 301, thus preventing water from seeping into the interior of the water inlet port 301 or adhering to the sealing surface of the water inlet port 301 under negative pressure.

[0037] The extension direction of the flushing port 304 forms an inclination angle β with the extension direction of the water inlet port 301, and the inclination angle β is 100-120°.

[0038] The angle β between the extension direction of the flush port 304 and the water inlet port 301 is limited to 100-120°. This angle range is optimized by fluid dynamics design so that the water flow vertically input into the water inlet port 301 is guided by the baffle plate 35 in the switching chamber and the water flow turns gently, avoiding the impact loss caused by the small angle. This ensures that the water flow discharged from the flush port 304 maintains sufficient impact kinetic energy and flows directly from the water inlet at the bottom of the toilet to the drain, forming a high-efficiency siphon or direct flush suction to quickly remove the sediment at the bottom.

[0039] The baffle 34 is provided with an air intake shield 341 on the side near the air intake port 302, and the air intake shield 341 is adapted to the air intake port 302; the baffle 34 is provided with a water inlet shield 342 on the side near the water inlet port 301, and the water inlet shield 342 is adapted to the water inlet port 301.

[0040] Since the diameter of the air intake port 302 is smaller than that of the water inlet port 301, the common port 303, and the flushing port 304, this application designs the air intake shield 341 and the water inlet shield 342 differently according to the port diameters. This allows the small-diameter air intake shield 341 to concentrate the sealing pressure, further improving the sealing effect under negative pressure conditions. The large-diameter water inlet shield 342, through full-diameter surface contact, ensures the sealing reliability during high-flow flushing and avoids sealing failure due to excessive water pressure.

[0041] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
