The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

At present, products of the bathing faucet in the market are mainly divided into a common cold and hot water mixing faucet, a multi-water-path switching cold and hot water mixing faucet and a constant-temperature water mixing faucet, and the products can basically meet the requirements of most users on bathing in the market. However, with the continuous increase of consumption level, the requirements of users on bath quality are also increased year by year, and simple multifunctional water outlet and constant-temperature water outlet can not meet the requirements of users. Users tend to pursue higher-grade living enjoyment, mineral bath and flower fragrance bath are popularized in the aspect of bathing, however, the various bathing methods with the bathing agents usually put the bathing agents into a bathtub in advance before each time of washing, so that the user experience is reduced, the bathtub also has the problems of large occupied area, and the practicability is poor in the scenario that the bathing room area is not wide. Therefore, the existing bathing faucet is poor in overall integration level and cannot meet the multifunctional bathing requirement of a user.

Therefore, the invention provides a multifunctional constant-temperature faucet with a skin moistening and comfortable bathing function, and particularly relates to a faucet product integrating a replaceable filter element, multi-water-path switching and constant temperature water outlet. The user can select various water outlet modes according to the actual bathing requirement of the user, select constant water outlet temperature and water outlet flow, and further select functional water or common water passing through the filter element under different water outlet modes, wherein the functional water passing through the filter element can also have the effects of beautifying, cleaning, moistening and pharmacology. Therefore, compared with other faucet products in the market, the bathing faucet provided by the invention can realize the multifunctional integration of the bathing faucet and meet the high-quality bathing requirements of users.

A bath tap according to an embodiment of the invention will now be described with reference to figures 1 to 10.

Referring to fig. 1, a shower faucet 100 according to an embodiment of the present invention may include a thermostatic valve 10, a waterway switching mechanism 20, and a functional assembly 21, wherein a water inlet end of the thermostatic valve 10 is connected to a cold water inlet pipe and a hot water inlet pipe, respectively, and the thermostatic valve 10 is configured to mix cold water entering from the cold water inlet pipe and hot water entering from the hot water inlet pipe to obtain mixed water and perform thermostatic control on the mixed water. The waterway switching mechanism 20 has a first waterway and a second waterway, the water inlets of the first waterway and the second waterway are connected with the water outlet end of the thermostatic valve 10, the water outlets of the first waterway and the second waterway are used for connecting with the external water outlet interface, wherein the first waterway is used for providing functional water, and the second waterway is used for providing ordinary water. The functional component 21 is disposed in the first waterway and is used for processing water in the first waterway to obtain functional water.

Specifically, the bath faucet 100 according to the embodiment of the present invention may thermostatically adjust the temperature of the mixed water through the thermostatic valve 10 to adjust the temperature of the mixed water to a target temperature (e.g., 40-50 ℃) set by a user. Specifically, the hot water inlet pipe may be connected to a hot water outlet of the water heater, and the thermostatic valve 10 is connected to a water outlet of the hot water inlet pipe and a water outlet of the cold water pipe. For example, the thermostatic valve 10 in this embodiment is a three-port valve, a first end of which is connected to the water outlet of the hot water inlet pipe, a second end of which is connected to the water outlet of the cold water inlet pipe, a third end of which is a mixed water thermostatic water outlet, and the target outlet water temperature is a temperature preset by the user (i.e., the above-mentioned target temperature).

It should be noted that the outlet thermostatic mode implemented by the thermostatic valve 10 in this embodiment adopts the physical characteristic of the mechanical thermostatic valve core, and the mixing ratio of the cold water and the hot water is controlled by the mechanical thermostatic valve core, so as to adjust the outlet water temperature to the temperature preset by the user. The valve core material of the thermostatic valve 10 may include paraffin and/or memory alloy. The valve core material in the embodiment is sensitive to temperature change, and when the valve core material senses the change of the ambient temperature, the volume of the valve core material changes along with the change of the ambient temperature, so that the mixing proportion of cold water and hot water can be controlled.

Specifically, a memory alloy valve core with high sensitivity can be arranged at the position of the water outlet at the third end of the thermostatic valve 10. The user may rotate the thermostat on the thermostatic valve 10 to set the target temperature of the mixed water, e.g. to 45 ℃. When the mixed temperature of cold water and hot water exceeds 45 ℃ or is lower than 45 ℃, the memory alloy valve core senses the temperature and then enables the volume of the valve core to change through extension and contraction so as to change the flow of the hot water and the cold water at the first end and the second end of the thermostatic valve 10, and therefore the mixed water outlet temperature at the third end is adjusted to be 45 ℃ of the target temperature, the bathing faucet of the embodiment can solve the problem that the mixed water is suddenly cold and suddenly hot in the bathing process of a user, the constant temperature adjustment of the mixed water can be achieved, and the user experience is improved.

The waterway switching mechanism 20 in this embodiment can switch the flow direction of the mixed water at the outlet end of the thermostatic valve 10 to provide regular water or functional water to the user. In this embodiment, the waterway switching mechanism 20 is provided with a first waterway and a second waterway, wherein both the first waterway and the second waterway are connected to the thermostatic valve 10, and the user can adjust the waterway switching mechanism 20 to switch the mixed water at the water outlet end of the thermostatic valve 10 to the first waterway or to the second waterway. When the water is switched to the first water channel, the functional component 21 arranged on the first water channel can filter the mixed water after constant temperature, so as to obtain functional water through treatment, and the functional water is output to an external water outlet interface for a user to use; when the water outlet port is switched to the second water path, the second water path can directly output the mixed water (namely common water) with constant temperature to the external water outlet port for the user to use.

Referring to fig. 2, the bathing faucet 100 of an embodiment of the present invention may further comprise a flow control valve 30. The flow rate adjusting valve 30 in this embodiment is provided between the thermostat valve 10 and the waterway switching mechanism 20, and the flow rate adjusting valve 30 is used to adjust the flow rate of the mixed water.

In some examples, the bathing faucet 100 further comprises a flow adjustment knob 120, the flow adjustment knob 120 is connected to the flow adjustment valve core 109 of the flow adjustment valve 30, for example, the flow adjustment valve core 109 can be driven to move by the flow adjustment knob 120, so as to adjust the flow of the mixed water.

As shown in fig. 3, the flow regulating valve 30 is provided at the water outlet end of the thermostatic valve 10. When a user needs to provide mixed water with a larger flow or a smaller flow by the bathing faucet 100, the flow of the mixed water can be adjusted by adjusting the valve of the flow adjusting valve 30, so as to meet the bathing requirement of the user for adjusting the water flow.

Referring to fig. 4, the waterway switching mechanism 20 according to the embodiment of the present invention may further include a two-way waterway switching valve 22 and a one-way check valve 23, in addition to the functional assembly 21. The water inlet end of the two-way waterway switching valve 22 is connected to the water outlet end of the flow control valve 30, and the two water outlet ends of the two-way waterway switching valve 22 are respectively connected to the water inlet of the first waterway and the water inlet of the second waterway. A one-way check valve 23 is provided in the first waterway and behind the functional component 21, the one-way check valve 23 to prevent the functional water from flowing backward.

As shown in fig. 3, the two-way water path switching valve 22 has two water outlet ends, wherein the first water path is a water path through which the mixed water flowing out from one water outlet end of the two-way water path switching valve 22 flows to the functional component 21 and the one-way check valve 23, and the second water path is a water path through which the mixed water flowing out from the other water outlet end of the two-way water path switching valve 22 flows to the water outlet end of the one-way check valve 23. The first water path from the functional module 21 to the one-way check valve 23 can provide functional water, and the second water path from the water outlet of the two-way water path switching valve 22 to the water outlet of the one-way check valve 23 can provide normal water, i.e. mixed water flowing out of the thermostatic valve 10. The one-way check valve 23 in this embodiment prevents the functional water at the outlet end of the functional module 21 from flowing back and damaging the functional module 21.

It should be noted that, in the present embodiment, the functional component 21 disposed on the first waterway may include: the water quality filtering core and/or the skin moistening core, wherein, the skin moistening core has an agent adding groove for placing at least one of an emollient, a skin beautifying agent and a medicinal agent.

Specifically, the filter element in this embodiment may be a water filtering filter element, or a skin moistening filter element, or a combined filter element composed of a water filtering filter element and a skin moistening filter element.

When the filter core only filters the filter core for the quality of water, the accessible quality of water filters the mixed water of first water route water inlet and filters. For example, a filter screen is arranged on the water quality filter element, and the filter screen can be a water quality filter material which can filter silt, suspended matters, residual chlorine, scale and the like in water, such as PP cotton, KDF, MSAP (scale inhibiting material) and the like. This embodiment can carry out the cleaning to the mixed water through the application of water quality filter core to satisfy the user to the purification demand of quality of water.

When the filter core is only for the skin lotion filter core, the accessible skin lotion filter core carries out the conversion with the mixed water of first water route water inlet and obtains the functional water that has the skin lotion function. For example, the skin moistening filter element is provided with an agent adding groove, wherein an emollient, a skin beautifying agent, a skin cleaning agent, a medicinal agent, a mineral agent and the like can be placed in the agent adding groove, and particularly, the agent package can be placed in the agent adding groove. It should be noted that the present description is only a specific implementation manner of one possible implementation manner of the functional water obtaining manner, and the obtaining manner of the functional water in this embodiment is not specifically limited herein.

When the filter element is a combined filter element, a skin moistening filter element can be arranged below the water quality filtering filter element, and after the mixed water at the water inlet of the first water channel is filtered by the water quality filter element, the mixed water is mixed with an agent through the skin moistening filter element to obtain functional water with a skin moistening function, so that the effects of healthy bathing such as skin beautifying, skin cleaning, pharmacology and the like can be realized on the basis of water quality filtering.

As an example, referring to fig. 3, when a user needs to use ordinary water, the two-way waterway switching valve 22 may be switched to allow the water inlet of the second waterway to flow into the mixed water after being kept at a constant temperature, and then the second waterway directly outputs the mixed water to the water outlet end of the one-way check valve 23 and to the external water outlet interface for the user to use. When the user needs to use the functional water, the two-way waterway switching valve 22 can be switched to enable the water inlet of the first waterway to flow into the mixed water after the constant temperature, the mixed water flows to the water quality filtering filter element or the skin moistening filter element or the combined filter element obtained by combining the water quality filtering filter element and the skin moistening filter element, the functional water is obtained through the filtering treatment of the filter element, and then the functional water is output to the water outlet end of the one-way check valve 23 and is output to the external water outlet interface for the user to use.

Referring to fig. 5 and 6, the bathing faucet 100 of the present invention may further include a three-way waterway switching valve 40. As shown in fig. 5, the three-way waterway switching valve 40 may be connected between the flow control valve 30 and the two-way waterway switching valve 22, or, as shown in fig. 6, between the water outlets of the first and second waterways and the external water outlet port, i.e., between the water outlet end of the waterway switching mechanism 20 and the external water outlet port.

Wherein, the external water outlet interface can comprise a top shower outlet interface 41, a handheld shower outlet interface 42 and a lower water outlet interface 43. Specifically, the three-way waterway switching valve 40 has three water outlet ends. Referring to fig. 3, three water outlets can be connected to the top shower outlet 41, the handheld shower outlet 42, and the lower outlet 43, respectively.

In an embodiment of the present invention, when the three-way waterway switching valve 40 is connected between the water outlets of the first waterway and the second waterway and the external water outlet, the water inlet end of the three-way waterway switching valve 40 is connected to the water outlets of the first waterway and the second waterway, and the three water outlet ends of the three-way waterway switching valve 40 are correspondingly connected to the top shower water outlet 41, the handheld shower water outlet 42 and the bottom water outlet 43.

When the three-way waterway switching valve 40 is connected between the flow control valve 30 and the two-way waterway switching valve 22, the water inlet end of the three-way waterway switching valve 40 is connected to the water outlet end of the flow control valve 30, two of the three water outlet ends of the three-way waterway switching valve 40 are correspondingly connected to the top shower outlet 41 and the bottom shower outlet 43, and the other of the three water outlet ends of the three-way waterway switching valve 40 is connected to the hand shower outlet 42.

In this embodiment, the filter element may be combined with any one or two or all of the water paths corresponding to the top shower outlet 41, the handheld shower outlet 42 or the lower outlet 43, so as to implement different combinations of water outlet modes and meet the use requirements of users.

Specifically, when the user needs that each outlet can be applied to the filtered functional water, as shown in fig. 3, the water inlet end of the three-way waterway switching valve 40 may be connected to the water outlet end of the waterway switching mechanism 20, or the water outlets of the first waterway and the second waterway, and then the three water outlet ends of the three-way waterway switching valve 40 are correspondingly connected to the top shower outlet 41, the handheld shower outlet 42, and the lower outlet 43, respectively. Therefore, each water outlet interface can output functional water, and the use requirements of users are met.

Specifically, when the user needs to output the normal water through each outlet, the user can obtain the mixed water through each outlet by switching the waterway switching mechanism 20, that is, switching the two-way waterway switching valve 22 to allow the mixed water to flow into the inlet of the second waterway, and allowing the mixed water to flow into the three-way waterway switching valve 40. Similarly, when the user needs each water outlet port to output the functional water, the user only needs to switch the waterway switching mechanism 20, that is, switch the two-way waterway switching valve 22, so that the mixed water flows into the water inlet of the first waterway, flows into the three-way waterway switching valve 40 after flowing to the functional assembly 21 and the one-way check valve 23, and then rotates the three-way waterway switching valve 40 to the corresponding water outlet port, so as to obtain the functional water through the water outlet port. It should be noted that, in the installation manner of the three-way waterway switching valve 40 capable of acquiring functional water from all three water outlets, the output waterways of the functional water are increased, and thus the number of waterway inflection points is increased, which may cause a certain head loss, and further may reduce the flow rate of the water outlet. Therefore, the three-way waterway switching valve 40 may be installed in the following manner.

Specifically, to avoid head loss in the waterway, the filter element may be combined with one or both of the water outlets, for example, the hand held shower outlet 42.

Referring to fig. 7, when the user only needs to access the outlet port 42 of the hand-held shower head to obtain functional water, the inlet end of the three-way waterway switching valve 40 may be connected to the outlet end of the flow control valve 30, then the outlet end of the three-way waterway switching valve 40 corresponding to the outlet port 42 of the hand-held shower head is connected to the inlet end of the waterway switching mechanism 20, the remaining outlet ends of the three-way waterway switching valve 40 are directly connected to the corresponding outlet ports, and then the outlet port 42 of the hand-held shower head is connected to the outlets of the first waterway and the second waterway. When a user obtains functional water through the handheld shower water outlet interface 42, the three-way waterway switching valve 40 can be switched to enable a water outlet end corresponding to the handheld shower water outlet interface 42 in the three-way waterway switching valve 40 to output mixed water to the two-way waterway switching valve 22, the mixed water is filtered by the filter element in the first waterway to obtain functional water, and the functional water is output to the handheld shower water outlet interface 42 to enable the user to obtain the functional water through the handheld shower water outlet interface 42.

Of course, the user can also obtain normal water from the hand-held shower outlet 42 through the two-way waterway switching valve 22. Specifically, when the user obtains the general water through the outlet interface 42 of the handheld shower, the three-way waterway switching valve 40 may be switched to allow the outlet end of the three-way waterway switching valve 40 corresponding to the outlet interface 42 of the handheld shower to output the mixed water to the two-way waterway switching valve 22, and the two-way waterway switching valve 22 may be adjusted to the second waterway to output the mixed water to the outlet interface 42 of the handheld shower through the second waterway, so that the user obtains the general water through the outlet interface 42 of the handheld shower.

In addition, the user can directly obtain ordinary water from the top shower outlet 41 and the lower outlet 43.

Referring to fig. 8, the bathing faucet 100 of the present embodiment may further include a monitoring assembly 50, wherein the monitoring assembly 50 is configured to monitor the flow rate and/or temperature of the mixed water.

Specifically, as shown in fig. 3 or fig. 7, the monitoring component 50 may include: a flow sensor 51, a temperature sensor 52, a controller 53, a display 54 and a power supply part 55, wherein the flow sensor 51 is used for detecting a flow signal of the mixed water, and the temperature sensor 52 is used for detecting a temperature signal of the mixed water; the controller 53 is respectively connected with the flow sensor 51 and the temperature sensor 52, and the controller 53 is used for receiving the flow signal and the temperature signal and sending out a display control signal according to the flow signal and the temperature signal; the display screen 54 is connected with the controller 53, and the display screen 54 is used for receiving the display control signal and displaying the temperature and the flow according to the display control signal; the power supply unit 55 is used to supply power to the flow sensor 51, the temperature sensor 52, the controller 53, and the display 54.

Specifically, the bathing faucet 100 may be provided with a flow sensor 51 and a temperature sensor 52, and the flow sensor 51 and the temperature sensor 52 may be specifically disposed at the water outlet end of the flow regulating valve 30 to detect the flow rate and the temperature of the mixed water at the water outlet end, and the sensors may transmit the respectively detected flow rate and temperature values to a controller 53, and the controller 53 is disposed on the circuit board of the bathing faucet 100. After receiving the signals, the controller 53 sends out display control signals to the display screen 54, so as to display the flow value and the temperature value of the current mixed water through the display screen 54. After the user knows the flow value and the temperature value of the current mixed water through the display screen 54, the temperature adjusting device of the thermostatic valve 10 can be adjusted according to the actual requirement so as to adjust the target temperature, adjust the flow adjusting valve 30 and adjust the current mixed water flow so as to meet the current bathing requirement of the user.

In this embodiment, detect mixed discharge and temperature through the sensor to flow and temperature are shown through display screen 54, so that the user carries out parameter adjustment according to actual demand, thereby can promote the interactive experience between user and the product, promote user's bathing quality.

It should be noted that fig. 3 and 7 only show the power supply unit 55 supplying power to the controller 53, and the rest of the electronic devices such as the flow sensor 51, the temperature sensor 52 and the display 54 also need the power supply unit 55 to supply power. However, since the number of electronic components is small, the power supply element 55 is required to supply a current of several tens of milliamperes.

The power unit 55 in this embodiment may include at least one of a dry battery, a storage battery, and a water flow driving motor 551, wherein the water flow driving motor 551 is disposed between the thermostatic valve 10 and the flow rate adjusting valve 30, and the water flow driving motor 551 includes an electric power output terminal, wherein when the water flow driving motor 551 operates, a rotor of the water flow driving motor 551 cuts a magnetic stator of the water flow driving motor 551 to generate electric power, and the electric power is output through the electric power output terminal.

Specifically, the power supply unit 55 may be a dry battery with a disposable service life, a rechargeable battery, or a water flow driving motor 551. The water flow driving motor 551 in this embodiment has two functions. The first function is to control the water pressure of the mixed water. In view of the current high-rise users, when the bathing faucet 100 is used, the water pressure is generally low, the water flow is small, and water cannot flow out. In this regard, in the present embodiment, a water flow driving motor 551 may be provided between the thermostatic valve 10 and the flow rate adjusting valve 30, and the water pressure may be controlled by the driving motor to meet the user's use requirement. The second function is that when the water flow driving motor 551 operates normally, the rotor in the water flow driving motor 551 cuts the stator in the motor to generate electromagnetic induction phenomenon and generate current, and then the current is output to each electronic device through the electric energy output end to meet the power supply requirement of each electronic device, so that the energy consumption is saved, the association between the external power supply and other modes under the wet environment of the bathroom is avoided, and the absolute safety of the power consumption of a user is ensured.

As shown with reference to fig. 3 or 7, the monitoring component 50 may also include a timer 56. The timer 56 is connected with the controller 53, and the timer 56 is used for timing the service life of the bathing faucet 100; the controller 53 is further configured to control the display 54 to send a prompt message for replacing the functional component 21 when the duration of use is greater than a first preset threshold and/or the water passing amount of the functional component 21 is greater than a second preset threshold.

Specifically, the controller 53 may control the timer 56 according to the received flow rate signal. In order to prevent the filter element from losing effect after being used for a long time, the using time of the filter element can be timed. In particular, a further flow sensor may be provided on the first water circuit, such as between the functional component 21 and the one-way check valve 23, or on the water outlet end of the one-way check valve 23. When another flow sensor detects a flow signal, the flow signal may be sent to the controller 23. After receiving the flow signal, the controller 23 may determine that the first water channel is outputting functional water, and control the timer 56 to time, and when the controller does not detect the flow signal transmitted by another flow sensor, control the timer 56 to stop timing, thereby counting the usage duration of the filter element in the period of time, and storing the usage duration in the buffer. When the user uses the functional water again, the controller continues to store the service life of the current filter element, and accumulates the service life of the current filter element with the service life in the previous cache until the accumulated service life is greater than a first preset threshold (for example, 30 h), and controls the display screen 54 to send out prompt information for replacing the functional component 21. Meanwhile, the controller 53 may also calculate the water passing amount of the functional component 21 according to the flow signal of another flow sensor, and when the water passing amount is greater than a second preset threshold (e.g. 30 cubes), the controller 53 may control the display 54 to send out a prompt message for replacing the functional component 21.

Referring to fig. 3, as a specific example, the multifunction of the shower faucet of the present invention will be explained.

Specifically, cold water and hot water can enter a product through a cold water inlet pipeline and a hot water inlet pipeline of a user's home, are mixed in the thermostatic valve 10 and then enter the flow regulating valve 30, and then enter the two-way waterway switching valve 22, if a valve core of the two-way waterway switching valve 22 is rotated to select a common waterway to output water, the common waterway, namely the second waterway, directly enters the valve core of the three-way waterway switching valve 40 without passing through a filter core, and a terminal water output mode, such as top shower water output, hand shower water output or lower water output, is determined by a rotation gear of the valve core; when the valve body of the two-way waterway switching valve 22 is rotated to select the functional waterway discharge, the functional waterway, i.e., the first waterway, passes through the filter element and enters the valve body of the three-way waterway switching valve 40, and the rotation position of the valve body determines the terminal discharge mode.
