Description

Technical Field

[0001] This utility model relates to the field of sensor faucets, and in particular to a dual-control sensor faucet. Background Technology

[0002] Existing sensor faucets are equipped with solenoid valves for controlling the flow of water. Common solenoid valves typically employ a pilot valve structure, opening their movable end by releasing pressure and closing it by storing pressure. The movable end controls the flow between the faucet's inlet and outlet. Because the solenoid valve needs to release pressure upon activation, existing sensor faucets require a dedicated passage on the valve seat to connect with the solenoid valve's pressure relief port. This complicates the valve seat structure, increases production costs, and significantly raises mold costs and processing difficulties for manufacturers. Furthermore, the complex structure leads to a lower yield rate in finished products.

[0003] To address the manufacturing issues of existing valve core seats, a novel exhaust structure and dual-waterway structure for an induction faucet solenoid valve have been developed (Chinese Patent Publication No. CN221003925U). This structure uses a connecting component to link the solenoid valve and the valve core seat, ensuring pressure relief for the solenoid valve and effectively simplifying the valve core seat structure. However, this dual-waterway structure has limitations because the end of the valve core seat used to connect the dual-outlet valve cores is on the side of the valve core seat (i.e., the end of the valve core seat with the first and second inlet holes is on the side of the valve core seat). Therefore, this dual-waterway structure is not suitable for current applications. Some side-opening faucets (i.e. faucets with handles on the side) have a dual-outlet valve core and valve core seat. One end of the valve core and valve core seat with the first and second inlet holes is installed in a mounting sleeve on the side of the faucet. The mounting sleeve is connected to the side of the faucet body. The solenoid valve is located inside the faucet body. However, due to the small size of the mounting sleeve, the diameters of the first and second inlet holes are also very small. Therefore, it is difficult to install commonly used water circuit components (such as pressure reducing valves and filter cartridges) in the first inlet hole to protect the solenoid valve (the first inlet hole is used to supply water to the first and second water passages controlled by the solenoid valve).

[0004] In view of the above problems, it is necessary to study a dual-control sensor faucet that can install existing water circuit functional components in the valve core seat. Utility Model Content

[0005] The purpose of this utility model is to provide a dual-control sensor faucet that can install existing water circuit functional components in the valve core seat.

[0010] A first sealing ring is sandwiched between the peripheral wall of the connecting member and the inner wall of the water passage cavity. The first sealing ring is higher than the annular groove of the connecting member. A second sealing ring is sandwiched between the solenoid valve and the inner wall of the water passage cavity.

[0051] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0052] Example 1:

[0053] Cooperate Figures 1 to 11 As shown, in Embodiment 1 of this utility model, the dual-control sensor faucet includes a faucet body 1, a spout 2, a dual-outlet valve core 3, a valve core seat 4, a connecting piece 5, a solenoid valve 6, and a sensor 7. The faucet body 1 includes a faucet main body 11 and a water outlet body 12 connected to the side of the faucet main body 11. The faucet main body 11 is vertically continuous, and the spout 2 is installed on the water outlet body 12. The valve core seat 4 is disposed in the faucet main body 11, and the valve core seat 4 has a valve core cavity 41 and a water passage cavity 42 and a water outlet cavity 43 communicating with the valve core cavity 41. The valve core cavity 41 is located at the top of the valve core seat 4. The water passage cavity 42 and the water outlet cavity 43 are arranged vertically and are lower than the valve core cavity 41. The water passage cavity 42 and the water outlet cavity 43 are connected through a water passage hole 44. The water passage cavity 42 can be used to install water circuit components, and the water outlet cavity 43 is connected to the water outlet cavity 43. The nozzle 2 is connected; the dual-outlet valve core 3 is installed in the valve core cavity 41, and the sensing outlet 31 and manual outlet 32 ​​of the dual-outlet valve core 3 are respectively connected to the water passage cavity 42 and the water outlet cavity 43; the connecting piece 5 is sealed and installed in the water passage cavity 42, and the connecting piece 5 is provided with a movable water inlet channel 51 and a water outlet channel 52. The water inlet channel 51 is connected to the sensing outlet 31 through the water passage cavity 42, and the water outlet channel 52 is connected to the water outlet cavity 43 through the water passage hole 44; the connecting piece 5 is also provided with a pressure relief channel 53 that is connected to the water outlet cavity 43; the solenoid valve 6 is sealed and installed at the bottom of the valve core seat 4, and the movable end 61 of the solenoid valve 6 controls the movable connection between the water inlet channel 51 and the water outlet channel 52, and the pressure relief hole 62 of the solenoid valve 6 is connected to the pressure relief channel 53; the sensor 7 is installed on the faucet body 1 and electrically connected to the solenoid valve 6, and the sensor 7 controls whether the solenoid valve 6 is activated.

[0054] As described above, the dual-control sensor faucet of this invention arranges the dual-outlet valve core 3, valve core seat 4, connecting piece 5, and solenoid valve 6 sequentially from top to bottom within the faucet body 11. The water passage chamber 42 and water outlet chamber 43 of the valve core seat 4 are both arranged vertically. Given the large diameter and height of the faucet body 11, the dual-control sensor faucet of this invention has sufficient space to enlarge the inner diameter and height of the water passage chamber 42, providing ample room for the installation of existing water circuit components. Figure 1 and Figure 3 As shown, a pressure reducing valve A can be installed in the water passage chamber 42. The pressure reducing valve A can effectively reduce the impact of high water pressure caused by water hammer generated in the upstream water path on the solenoid valve 6, thus protecting the solenoid valve 6. The installation of the pressure reducing valve A also reduces the water hammer effect caused by the opening and closing of the solenoid valve 6 itself. Furthermore, a filter element can also be installed in the water passage chamber 42. The filter element can effectively prevent impurities in the water path from affecting the solenoid valve 6.

[0055] In the first embodiment of this utility model, the pressure relief channel 53 of the connecting member 5 may include an annular groove 531 disposed on the peripheral wall of the connecting member 5 and a groove 532 disposed on the lower periphery of the connecting member 5; while the solenoid valve 6 is sealed and installed at the lower opening of the water passage cavity 42 to prevent water leakage, and the pressure relief hole 62 of the solenoid valve 6 is connected to the water outlet cavity 43 in sequence through the groove 532, the annular groove 531 and the water passage hole 44.

[0056] In the first embodiment of this utility model, the water inlet channel 51 of the connecting member 5 may include at least one water inlet through hole 511 that runs vertically through the connecting member 5; the water outlet channel 52 of the connecting member 5 may include a main water outlet through hole 521 and at least one secondary water outlet through hole 522. The main water outlet through hole 521 is arranged in the vertical direction and has an opening on its lower side. The inner end of each secondary water outlet through hole 522 intersects and communicates with the main water outlet through hole 521, and the outer end of each secondary water outlet through hole 522 communicates with an annular groove 531, so that each secondary water outlet through hole 522 communicates with the water outlet chamber 43 through the annular groove 531 and the water passage hole 44; and the movable end 61 of the solenoid valve 6 actively blocks the lower opening of the main water outlet through hole 521 to control whether the water outlet channel 52 is connected to the water inlet channel 51.

[0057] In the first embodiment of this utility model, a first sealing ring a can be sandwiched between the peripheral wall of the connecting member 5 and the inner wall of the water passage cavity 42. The first sealing ring a can be sleeved on the peripheral wall of the connecting member 5. The first sealing ring a is higher than the annular groove 531 of the connecting member 5. The first sealing ring a makes the connecting member 5 sealed and installed in the water passage cavity 42, ensuring that the water from the sensing outlet 31 can only flow to the annular groove 531 through the inlet channel 51 and the outlet channel 52. A second sealing ring b can be sandwiched between the solenoid valve 6 and the inner wall of the water passage cavity 42. The second sealing ring b can be sleeved on the solenoid valve 6. The second sealing ring b is lower than the pressure relief hole 62 of the solenoid valve 6. The second sealing ring b makes the solenoid valve 6 sealed and installed at the lower opening of the water passage cavity 42.

[0058] In the first embodiment of this utility model, the valve core seat 4 has a water outlet 45 on its side wall that communicates with the water outlet chamber 43. The water outlet chamber 43 communicates with the water outlet 2 through the water outlet 45. Specifically, the water outlet 45 is connected to the water outlet 2 through a connecting pipe 8 inserted inside the water outlet body 12. This arrangement allows the faucet body 1 to be made of inexpensive materials (such as copper-zinc alloy or stainless steel, which do not meet the safety requirements for water flow). The connecting pipe 8 can be a rubber hose or a plastic pipe to ensure water flow safety.

[0059] In Embodiment 1 of this utility model, the side wall of the valve core seat 4 is also provided with a core-pulling hole 46 facing the water inlet, so as to facilitate the core-pulling of the valve core seat 4 during injection molding to form the water inlet 44. The core-pulling hole 46 is fitted with a plug 461 to prevent water leakage from the core-pulling hole 46.

[0060] In the first embodiment of this utility model, the valve core seat 4 is further provided with a first water inlet chamber 47 and a second water inlet chamber 48 that are arranged vertically through the valve core 3. The first water inlet 33 and the second water inlet 34 of the dual-outlet valve core 3 are respectively connected to the first water inlet chamber 47 and the second water inlet chamber 48. Regarding the dual-outlet valve core 3, it is an existing valve core that can output water in two different directions. The sensing water outlet 31 of the dual-outlet valve core 3 is connected to the water inlet channel 51 and the solenoid valve 6 controls whether water is discharged, thereby realizing sensing water discharge control. The manual water outlet 32 ​​of the dual-outlet valve core 3 is connected to the water outlet chamber 43, and the dual-outlet valve core 3 itself controls whether water is discharged from the manual water outlet 32, thereby realizing manual water discharge control.

[0061] In the first embodiment of this utility model, the valve core cavity 41 opening of the valve core seat 4 can be fitted with a pressure cap 411, which presses down on the dual-outlet valve core 3 to prevent the dual-outlet valve core 3 from coming out.

[0062] In the first embodiment of this utility model, the peripheral wall of the valve core seat 4 is provided with a support edge 49, and the bottom of the valve core seat 4 can be fitted with a fixing screw e. The heads of the support edge 49 and the fixing screw e respectively clamp the retaining edge 111 of the inner wall of the faucet body 11 to install the valve core seat 4 into the faucet body 11. The top opening of the faucet body 11 can be fitted with a decorative ring 13. The valve stem of the double-outlet valve core 3 passes through the decorative ring 13. The valve stem of the double-outlet valve core 3 is connected to an operating handle 9, which is located above the faucet body 11.

[0063] In one embodiment of this utility model, the sensor 7 can be installed on the faucet body 11 of the faucet body 1, and the installation position of the sensor 7 is adapted to the position when the user washes their hands. It should be noted that the sensor 7 can also be installed on the water outlet body 12.

[0064] Example 2:

[0065] Cooperate Figure 12 and Figure 13 As shown, the difference between Embodiment 2 and Embodiment 1 of this utility model lies in the different communication methods between the outlet 45 of the valve core seat 4 and the spout 2. Specifically, in Embodiment 2 of this utility model, the outlet 45 of the valve core seat 4 is connected to the spout 2 through the inner cavity of the water outlet body 12. This arrangement eliminates the need for an additional connecting pipe 8, but the faucet body 1 must meet the water flow safety requirements. The faucet can be made of copper or stainless steel that meet the water flow safety requirements.

[0066] In the second embodiment of this utility model, an upper sealing ring c and a lower sealing ring d are sandwiched between the valve core seat 4 and the faucet body 1, and the water outlet 45 is located between the upper sealing ring c and the lower sealing ring d, thereby preventing water from leaking out from between the valve core and the faucet body 1; the valve core seat 4 may be provided with an upper groove 401 and a lower groove 402 for the upper sealing ring c and the lower sealing ring d to be respectively fitted.

[0067] In the second embodiment of this utility model, the core-pulling hole 46 of the valve core seat 4 is located between the upper sealing ring c and the lower sealing ring d. The core-pulling hole 46 does not need to be equipped with a plug 461, and the core-pulling hole 46 is also used for water discharge.

[0068] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
