Description

Technical Field

[0001] This utility model relates to the technical field of automated temperature control systems for faucets, and more particularly to an intelligent water flow regulation module, which is especially suitable for supplying water to washbasins. Background Technology

[0002] The applicant has applied for a Chinese utility model patent with patent number CN202420856672.1 (publication number CN222229538U), which discloses a thermostat for controlling water temperature. The thermostat includes a valve seat with a cold water inlet channel, a hot water inlet channel, a first valve core mounting cavity, a second valve core mounting cavity, a cold water outlet channel, a hot water outlet channel, a mixing chamber, a third valve core mounting cavity, and a mixed water outlet channel. The mixing chamber is connected to the mixed water outlet channel. A first flow regulating valve core is installed in the first valve core mounting cavity. The cold water inlet channel is connected to the first inlet end of the first flow regulating valve core, and the first outlet end of the first flow regulating valve core is connected to the cold water outlet channel. The water outflow channel is connected, and the first moving valve plate of the first flow regulating valve core is driven to rotate by the first motor to regulate the cold water flow. The second flow regulating valve core is installed in the second valve core mounting cavity. The hot water inlet channel is connected to the second inlet end of the second flow regulating valve core, and the second outlet end of the second flow regulating valve core is connected to the hot water outflow channel. The second moving valve plate of the second flow regulating valve core is driven to rotate by the second motor to regulate the hot water flow. The balancing valve core is installed in the third valve core mounting cavity. The cold water outflow channel is connected to the cold water inlet of the balancing valve core, and the hot water outflow channel is connected to the hot water inlet of the balancing valve core. Both the cold water outlet and the hot water outlet of the balancing valve core are connected to the mixing chamber.

[0003] The two flow control valves not only regulate the outflow of water but also adjust the mixing ratio, leading to complex control. The controller integrates too many functions, resulting in poor flexibility. The balancing valve, located at the outlet, causes fluctuations in outlet water temperature, requiring simultaneous responses from the first motor, second motor, and balancing valve. This places extremely high demands on program control, resulting in a less than ideal user experience. Furthermore, the temperature control module, balancing module, water distribution module, and emergency on / off function are all integrated into a single housing, making housing manufacturing difficult. If customers only need a few modules, the entire thermostat must be replaced, as it lacks modular design for selective use. Moreover, the aforementioned controller cannot adjust the water flow rate.

[0004] Therefore, the existing automatic temperature control modules for faucets still need further improvement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an intelligent water flow regulation module with a reasonable structure that can intelligently adjust the output of hot and cold water per unit time, which is convenient to be selected and combined with other regulation modules in view of the current situation of the prior art.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an intelligent water flow regulation module, including a valve seat, characterized in that: the valve seat has a cold water inlet channel, a hot water inlet channel, a flow valve core mounting cavity, a cold water outlet channel and a hot water outlet channel, and the flow valve core mounting cavity is provided with a flow regulating valve core controlled by a motor, the flow regulating valve core can synchronously increase or decrease the water flow rate per unit time of the cold water outlet channel and the hot water outlet channel.

[0007] Preferably, there are two flow valve core mounting cavities, and two flow regulating valve cores, with one flow regulating valve core installed in each flow valve core mounting cavity; the cold water inlet channel is connected to the inlet end of one of the flow regulating valve cores, and the outlet end of the flow regulating valve core is connected to the cold water outlet channel; the moving valve plate of the flow regulating valve core is driven to rotate by a corresponding motor to regulate the flow rate of cold water flowing out of the first cold water outlet channel; the hot water inlet channel is connected to the inlet end of the other flow regulating valve core, and the outlet end of the flow regulating valve core is connected to the hot water outlet channel; the moving valve plate of the flow regulating valve core is driven to rotate by a corresponding motor to regulate the flow rate of hot water flowing out of the hot water outlet channel.

[0008] This method uses a dual-valve core structure to adjust the flow rate. Because there are two motors that adjust and control the corresponding flow rate adjustment valve cores, the overall control of flow rate adjustment is simpler, the program requirements are lower, and the adjustment is more precise. It is only necessary to simultaneously increase or decrease the outflow rate of the cold water outlet channel and the hot water outlet channel. In addition, the valve plate assembly of a single flow rate adjustment valve core is also simpler, and the most traditional flow rate adjustment valve plate assembly can be used.

[0009] As a preferred embodiment, each of the two flow control valve cores has its moving valve plate driven to rotate by one of the motors. Each motor can be connected to the moving valve plate via an independent gearbox, which simplifies the structure of a single gearbox.

[0010] Alternatively, the moving valve plates of the two flow control valve cores are driven to rotate by the same motor. Using only one motor reduces cost, but the gearbox structure is relatively complex, consisting of two output shafts connected to the motor shaft via only two sets of gear transmissions.

[0011] Preferably, the aforementioned flow control valve core includes a valve housing with an inlet end and an outlet end. The inlet end is located on the side of the valve housing, and the outlet end is located at the bottom of the valve housing. The valve housing contains a fixed valve plate, a movable valve plate, and a rotor. The movable valve plate is fixed to the bottom surface of the rotor. The output shaft of the motor is inserted into the rotor and can drive the rotor to rotate. The aforementioned flow control valve core has a simple structure, and the side inlet and bottom outlet design facilitates assembly into the valve seat.

[0012] To prevent leakage, a sealing gasket is provided between the bottom of the valve housing and the inner bottom wall of the flow valve core mounting cavity, and a sealing ring is provided between the outer peripheral wall of the valve housing and the inner peripheral wall of the flow valve core mounting cavity. This ensures that the incoming water must be regulated by the flow valve core before flowing into the cold water outlet channel or the hot water outlet channel.

[0013] To ensure a rational layout of the flow channels, as a preferred arrangement, the aforementioned cold water inlet and hot water inlet channels are arranged horizontally and coaxially. This facilitates the connection of the cold water inlet pipe, hot water inlet pipe, and outlet pipe to this module. All pipe connections are made from bottom to top, making pipework more convenient and efficient. Furthermore, one of the flow valve core mounting chambers and the cold water outlet channel are arranged vertically and coaxially, as are the other two. This vertically continuous arrangement facilitates product molding and makes core extraction during manufacturing easier. The flow valve core can be installed from top to bottom.

[0014] To facilitate connection of this water flow regulation module with other modules (such as pressure balance module and flow regulation module), each of the left and right sides of the valve seat is provided with a first joint portion that protrudes laterally, and the cold water inlet channel and the hot water inlet channel pass through the corresponding first joint portion; the upper end of the valve seat has a second joint portion that protrudes upward, and the cold water outlet channel and the hot water outlet channel pass through the corresponding second joint portion.

[0015] To ensure a rational layout of the flow channels, as an alternative preferred arrangement, the two flow valve core mounting cavities are arranged horizontally and coaxially, with the cold water inlet channel and hot water inlet channel facing downwards, and the cold water outlet channel and hot water outlet channel facing upwards. The flow valve core can be inserted horizontally.

[0016] Compared with existing technologies, the advantages of this utility model are as follows: the flow regulating valve core is controlled by a motor, providing a foundation for automated flow rate control; the flow regulating valve core can simultaneously increase or decrease the unit time flow rate of the cold water outlet channel and the hot water outlet channel, resulting in a more balanced synchronous adjustment of the cold and hot water flow rates per unit time, simplifying the control method, greatly improving the accuracy of water output control, and preventing instability in the final flow rate adjustment due to imbalances in the cold and hot water flow rates. This module is only used to regulate the flow rate of cold and hot water, making it convenient to select and use in conjunction with other modules (such as pressure balancing modules and flow regulation modules), thus enhancing its applicability.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-5 The image shown is the first embodiment of this utility model.

[0026] A smart water flow regulation module includes a valve seat 1, which has a cold water inlet channel 1a, a hot water inlet channel 1b, a flow valve core mounting cavity 1e, a cold water outlet channel 1c, and a hot water outlet channel 1d. There are two flow valve core mounting cavities 1e and two flow regulating valve cores 3, with one flow regulating valve core 3 installed in each flow valve core mounting cavity 1e.

[0027] The cold water inlet channel 1a is connected to the inlet end 3a of one of the flow regulating valve cores 3, and the outlet end 3b of the flow regulating valve core 3 is connected to the cold water outlet channel 1c. The moving valve plate 33 of the flow regulating valve core 3 is driven to rotate by the corresponding motor 2 to regulate the flow rate of the cold water flowing out of the cold water outlet channel 1c.

[0028] The hot water inlet channel 1b is connected to the inlet end 3a of another flow regulating valve core 3, and the outlet end 3b of the flow regulating valve core 3 is connected to the hot water outlet channel 1d. The moving valve plate 33 of the flow regulating valve core 3 is driven to rotate by the corresponding motor 2 to regulate the hot water flow rate of the hot water outlet channel 1d.

[0029] The two flow control valve cores 3 can simultaneously increase or decrease the flow rate per unit time of the cold water outlet channel 1c and the hot water outlet channel 1d.

[0030] In this embodiment, the moving valve plates 33 of the two flow control valve cores 3 are each driven to rotate by a motor 2. Each motor 2 can be connected to the moving valve plate through an independent gearbox, and the structure of a single gearbox is simpler.

[0031] Each flow control valve core 3 includes a valve housing 31 with an inlet end 3a and an outlet end 3b. The inlet end 3a is located on the side of the valve housing 31, and the outlet end 3b is located at the bottom of the valve housing 31. A sealing gasket 35 is provided between the bottom of the valve housing 31 and the inner bottom wall of the flow control valve core mounting cavity 1e. A sealing ring 36 is provided between the outer peripheral wall of the valve housing 31 and the inner peripheral wall of the flow control valve core mounting cavity 1e. The valve housing 31 contains a fixed valve plate 32, a movable valve plate 33, and a rotor 34. The movable valve plate 33 is fixed to the bottom surface of the rotor 34. The output shaft of the motor 2 is inserted into the rotor 34 and can drive the rotor 34 to rotate.

[0032] The cold water inlet channel 1a and the hot water inlet channel 1b are arranged laterally and coaxially. One of the flow valve core mounting chambers 1e and the cold water outlet channel 1c are arranged longitudinally and coaxially, while the other flow valve core mounting chamber 1e and the hot water outlet channel 1d are arranged longitudinally and coaxially. Each of the left and right sides of the valve seat 1 has a first joint portion 11 that protrudes laterally, through which the cold water inlet channel 1a and the hot water inlet channel 1b pass. The upper end of the valve seat 1 has a second joint portion 12 that protrudes upwards, through which the cold water outlet channel 1c and the hot water outlet channel 1d pass.

[0033] The flow control valve core 3 is controlled by the motor 2, providing the foundation for automated flow control. The flow control valve core 3 can simultaneously increase or decrease the flow rate per unit time in both the cold and hot water outlet channels. This synchronized adjustment of the cold and hot water flow rates per unit time results in a more balanced control method, simplifies the control process, and improves the accuracy of water output control. It prevents instability in the final flow rate adjustment due to imbalances in the cold and hot water flow rates. This module is only used to adjust the flow rates of cold and hot water, making it easy to select and use in conjunction with other modules (such as pressure balancing modules and flow regulation modules), thus enhancing its applicability.

[0034] like Figure 6 , 7 The following is a second embodiment of the present invention.

[0035] The difference between this embodiment and the first embodiment is that the moving valve plates 33 of the two flow control valve cores 3 are driven to rotate by the same motor 2. The two flow control valve core mounting cavities 1e are arranged laterally and coaxially, the cold water inlet channel 1a and the hot water inlet channel 1b are arranged vertically downward, and the cold water outlet channel 1c and the hot water outlet channel 1d are arranged vertically upward.
