Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, and in particular to a temperature-regulating solenoid valve and a faucet. Background Art

[0002] An induction faucet generally controls the opening and closing of water flow in cooperation with a solenoid valve through an induction control device. Most of the induction faucets on the market are single-cold structures, and only the opening and closing of the solenoid valve need to be controlled. With the wide application of induction faucets in scenarios such as families and hotels, single-cold water output has been difficult to meet the market demand. Therefore, more and more solenoid valves have temperature-regulating functions. For example, a micro bistable solenoid valve with a temperature-regulating function disclosed in Chinese Patent CN211667200U adjusts the outlet water temperature through a temperature-regulating valve core and controls the opening and closing of the outlet water through the solenoid valve. However, the first channel and the second channel are arranged in parallel along the X-axis, the first connection port and the second connection port are located on the Y-axis perpendicular to the X-axis, and the temperature-regulating valve core is arranged in the Z-axis direction perpendicular to the Y-axis. In other words, in this solution, each component extends along the three directions of the X-axis, the Y-axis, and the Z-axis, so its radial dimension is large, and the appearance of the faucet is easily limited. In addition, since the existing faucets are generally close to the wall, when installed under the counter, the position of the water inlet joint is also relatively close to the wall, resulting in a small installation operation range, and even the problem that the water inlet joint is difficult to connect to the water pipe. Summary of the Utility Model

[0003] The utility model discloses a temperature-regulating solenoid valve, aiming to improve the problems of large radial dimension of the existing temperature-regulating solenoid valve and difficulty in connecting to the water pipe when installed against the wall.

[0004] The utility model adopts the following scheme:

[0005] A temperature-regulating solenoid valve includes a valve seat extending vertically. An electromagnetic valve head and a water inlet joint are respectively installed at the upper and lower ends of the valve seat. A first installation cavity, a second installation cavity, a cold water flow channel, a hot water flow channel, a mixed water flow channel, and an outlet channel are formed in the valve seat. The first installation cavity is adaptively connected to a temperature-regulating valve to adjust the water flow ratio of the cold water flow channel and the hot water flow channel entering the mixed water flow channel. The electromagnetic valve head is installed in the second installation cavity to control the on-off of the mixed water flow channel and the outlet channel. Among them, the second installation cavity extends vertically, the outlet channel is arranged along the side wall of the second installation cavity and is parallel to the second installation cavity. The water inlet joint is provided with a cold water inlet pipe and a hot water inlet pipe corresponding to the cold water flow channel and the hot water flow channel. Both the cold water inlet pipe and the hot water inlet pipe are provided with a straight section extending vertically and a connecting section arranged at an angle to the straight section.

[0006] As a further improvement, a cold water inlet, a hot water inlet and a mixed water outlet are formed in the first installation cavity. The cold water inlet is communicated with the cold water flow channel, the hot water inlet is communicated with the hot water flow channel, and the mixed water outlet is communicated with the mixed water flow channel.

[0007] As a further improvement, the extending direction of the first installation cavity is perpendicular to that of the second installation cavity. The cold water inlet and the hot water inlet are arranged at the bottom of the first installation cavity, and the mixed water outlet is arranged on the side wall of the first installation cavity.

[0008] As a further improvement, the cold water flow channel, the hot water flow channel, the mixed water flow channel and the water outlet channel are all arranged to extend vertically.

[0009] As a further improvement, the second installation cavity is provided with an inlet communicated with the mixed water flow channel and an outlet communicated with the water outlet channel. The solenoid valve head is electrically connected to the control member and is driven by the control member to control the on-off of the inlet and the outlet.

[0010] As a further improvement, check valves are arranged in the straight sections of the cold water inlet pipe and the hot water inlet pipe.

[0011] As a further improvement, metal parts are embedded in the connecting sections of the cold water inlet pipe and the hot water inlet pipe.

[0012] As a further improvement, the solenoid valve head is threadedly connected to the second installation cavity, and the temperature regulating valve is pressed tightly in the first installation cavity through a gland.

[0013] As a further improvement, the cold water flow channel and the hot water flow channel are eccentrically arranged with respect to the cold water inlet pipe and the hot water inlet pipe, so that the first installation cavity can be arranged close to the center of the valve seat.

[0014] Another faucet is provided, which includes a faucet body and the temperature regulating solenoid valve as described in any one of the above. One end of the temperature regulating solenoid valve is sleeved in the faucet body, and the other end thereof is exposed outside the faucet body and is used for connecting the water pipe under the installation tabletop.

[0015] By adopting the above technical solutions, the following technical effects can be achieved by the present utility model:

[0016] 1. In the present application, the solenoid valve head and the water inlet joint are arranged at both ends of a valve seat extending vertically. The second installation cavity extends vertically, and the water outlet channel is arranged along the side wall of the second installation cavity and is parallel to the second installation cavity. That is, the solenoid valve head, the water inlet joint, and the water outlet channel are arranged in the same direction, making the temperature control solenoid valve as a whole slender, thereby reducing the radial size of the temperature control solenoid valve to facilitate adaptation to different product appearances. In addition, the water inlet pipe on the water inlet joint has a straight section arranged vertically and a connecting section arranged at an angle to the straight section, which can increase the operating space between the under-counter installation and the wall, thus facilitating the connection of the water pipe.

[0017] 2. The cold water flow channel, the hot water flow channel, the mixed water flow channel, and the water outlet channel all extend vertically to reduce the radial size of the valve seat, simplify the structure, and at the same time can also reduce the number of sliders of the mold, saving production costs. Preferably, the cold water flow channel and the hot water flow channel are eccentrically arranged with respect to the cold water inlet pipe and the hot water inlet pipe, so that the first installation cavity can be arranged close to the center of the valve seat, further ensuring the radial size of the temperature control solenoid valve and making the structure of the temperature control solenoid valve compact.

[0018] 3. Check valves are arranged in the straight sections of the cold water inlet pipe and the hot water inlet pipe. The setting of the check valves can prevent the backflow of water and cause the problem of water source pollution. At the same time, metal parts are embedded in the connecting sections of the cold water inlet pipe and the hot water inlet pipe, which can strengthen the connection strength of the cold water inlet pipe and the hot water inlet pipe. Among them, the metal parts can be copper or stainless steel. BRIEF DESCRIPTION OF THE DRAWINGS

Embodiment

[0033] Combined with Figures 1 to 13, this embodiment provides a temperature regulating solenoid valve, which includes a valve seat 1 extending vertically. Solenoid valve heads 2 and water inlet connectors 3 are respectively installed at the upper and lower ends of the valve seat 1. A first installation cavity 11, a second installation cavity 12, a cold water flow channel 13, a hot water flow channel 14, a mixed water flow channel 15 and a water outlet channel 16 are formed in the valve seat 1. The first installation cavity 11 is adaptively connected to a temperature regulating valve 4 to adjust the water flow ratio of the cold water flow channel 13 and the hot water flow channel 14 entering the mixed water flow channel 15. The solenoid valve head 2 is installed in the second installation cavity 12 to control the on-off of the mixed water flow channel 15 and the water outlet channel 16. Among them, the second installation cavity 12 extends vertically, the water outlet channel 16 is arranged along the side wall of the second installation cavity 12 and is parallel to the second installation cavity 12. The water inlet connector 3 is provided with a cold water inlet pipe 31 and a hot water inlet pipe 32 corresponding to the cold water flow channel 13 and the hot water flow channel 14. Both the cold water inlet pipe 31 and the hot water inlet pipe 32 are provided with a straight section 33 extending vertically and a connecting section 34 arranged at an angle to the straight section 33. Preferably, the angle between the connecting section 34 and the vertical direction is not greater than 30° and does not exceed the vertical projection range of the seat body.

[0034] Exemplarily, a cold water pipe is connected to the cold water inlet pipe 31, and a hot water pipe is connected to the hot water inlet pipe 32. The temperature regulating valve 4 is preferably a ceramic water distribution valve or a proportional valve. By rotating the temperature regulating valve 4, the water flow ratio of the cold water flow channel 13 and the hot water flow channel 14 entering the mixed water flow channel 15 can be realized, so as to adjust the water flow temperature in the mixed water flow channel 15. Among them, the on-off of the mixed water flow channel 15 and the water outlet channel 16 is controlled by the solenoid valve head 2. The water outlet channel 16 can be set to communicate with the water outlet nozzle of the faucet body. When the mixed water flow channel 15 and the water outlet channel 16 are conducted, water flows out in the water outlet channel 16 and is supplied to the user side from the water outlet nozzle. When the mixed water flow channel 15 and the water outlet channel 16 are cut off, no water flows out in the water outlet channel 16, and at this time, no water comes out of the water outlet nozzle. When in use, the user only needs to adjust and rotate the temperature regulating valve 4 to the required temperature. When using it next time, there is no need to adjust it again, and the water temperature state can still be maintained. Of course, in other embodiments, the temperature regulating valve 4 can also be set as a constant temperature valve core, not limited to this, and no specific limitation is made.

[0035] It should be noted that, in this embodiment, the solenoid valve head 2 and the water inlet connector 3 are arranged at both ends of the valve seat 1 extending vertically. The second installation cavity 12 extends vertically, and the water outlet channel 16 is arranged along the side wall of the second installation cavity 12 and is parallel to the second installation cavity 12, that is, the layout directions of the solenoid valve head 2, the water inlet connector 3 and the water outlet channel 16 are the same, so that the temperature regulating solenoid valve as a whole is slender, thereby reducing the radial size of the temperature regulating solenoid valve to facilitate adaptation to different product appearances. In addition, the water inlet pipe on the water inlet connector 3 has a straight section 33 arranged vertically and a connecting section 34 arranged at an angle to the straight section 33, which can increase the operating space between the under-counter installation and the wall, thus facilitating the connection of the water pipes.

[0036] In a preferred embodiment, a cold water inlet 111, a hot water inlet 112 and a mixed water outlet 113 are provided in the first installation cavity 11. The cold water inlet 111 is communicated with the cold water flow channel 13, the hot water inlet 112 is communicated with the hot water flow channel 14, and the mixed water outlet 113 is communicated with the mixed water flow channel 15. Specifically, the extending direction of the first installation cavity 11 is perpendicular to that of the second installation cavity 12. The cold water inlet 111 and the hot water inlet 112 are arranged at the bottom of the first installation cavity 11, and the mixed water outlet 113 is arranged on the side wall of the first installation cavity 11. Cold water enters the cold water flow channel 13 through the cold water inlet pipe 31, then flows through the cold water inlet 111, and then flows from the mixed water outlet 113 to the mixed water flow channel 15. Similarly, hot water enters the hot water flow channel 14 through the hot water inlet pipe 32, then flows to the hot water inlet 112, and then flows from the mixed water outlet 113 to the mixed water flow channel 15. A cold water inlet hole and a hot water inlet hole corresponding to and communicated with the cold water inlet 111 and the hot water inlet 112 are provided at the bottom of the temperature regulating valve 4, and a water outlet hole is provided on the side surface of the temperature regulating valve 4. By rotating the ceramic valve plate in the temperature regulating valve 4, the water inlet areas of the cold water inlet hole and the hot water inlet hole are adjusted, so as to adjust the cold water inlet ratio and the hot water inlet ratio.

[0037] On the basis of the above embodiment, in an alternative embodiment of the present utility model, the cold water flow channel 13, the hot water flow channel 14, the mixed water flow channel 15 and the water outlet channel 16 all extend vertically, so as to reduce the radial dimension of the valve seat, simplify the structure, and at the same time reduce the number of sliders of the mold, saving the production cost. Preferably, the cold water flow channel 13 and the hot water flow channel 14 are eccentrically arranged with respect to the cold water inlet pipe 31 and the hot water inlet pipe 32, so that the first installation cavity 11 can be arranged close to the center of the valve seat 1, further ensuring the radial dimension of the temperature regulating solenoid valve and making the structure of the temperature regulating solenoid valve compact. It should be mentioned that a water passing channel 17 is also arranged between the water outlet channel 16 and the second installation cavity 12. The water passing channel 17 penetrates through the outer wall of the valve seat 1 to facilitate the mold forming, and a plug 18 is provided at the opening of the water passing channel 17 and the seat body.

[0038] In another preferred embodiment, the second installation cavity 12 is provided with an inlet 121 communicated with the mixed water flow channel 15 and an outlet 122 communicated with the water outlet channel 16. The solenoid valve head 2 is electrically connected to the control member and is driven by the control member to control the on-off of the inlet 121 and the outlet 122. Among them, the control member can be a PCB. The control member is electrically connected to the sensing module and drives the solenoid valve head 2 to open and close correspondingly by receiving the signal of the sensing module. The structure and circuit principle of the solenoid valve head 2 are prior arts and will not be elaborated herein.

[0039] Based on the above embodiments, in an alternative embodiment of the present utility model, the solenoid valve head 2 is threadedly connected to the second installation cavity 12, and the temperature control valve 4 is pressed in the first installation cavity 11 through a gland 41. Specifically, the solenoid valve head 2 is provided with an external thread, and the second installation cavity 12 is provided with an internal thread. During installation, the solenoid valve head 2 is screwed into the second installation cavity 12.

During installation, the temperature control valve 4 is inserted into the positioning hole 114 for positioning, and the gland 41 is screwed into the first installation cavity 11 to press the temperature control valve 4 tightly.

The first flange 19 and the second flange 37 are locked by screws. Preferably, a metal gasket 38 is arranged below the second flange 37, and the screws sequentially pass through the metal gasket 38, the through hole 371 and the threaded hole 191 from bottom to top. The arrangement of the metal gasket 38 can enhance the connection strength of the water inlet joint 3. Among them, the top surface of the first flange 19 is used to abut against the bottom surface of the installation table to limit the temperature control solenoid valve in the vertical direction. Combining Figure 14 and Figure 15 , in another embodiment, the first flange 19 is provided with first through holes, the second flange 37 is correspondingly provided with second through holes for each first through hole, and the metal gasket 38 is provided with threaded holes. During installation, the screws sequentially pass through the first through holes and the second through holes from top to bottom to be screwed with the threaded holes on the metal gasket 38. Arranging the threaded holes on the metal gasket 38 can strengthen the thread strength and avoid the problem of thread slipping.

[0040] In other embodiments, check valves 35 are arranged in the straight sections 33 of the cold water inlet pipe 31 and the hot water inlet pipe 32. The arrangement of the check valves 35 can prevent the backflow of water and cause the problem of water source pollution.
