[0058] The embodiments of the present invention are described in detail below. Examples of the embodiments described below are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0059] At present, the products of bath faucets on the market are mainly divided into ordinary hot and cold water mixing faucets, hot and cold water mixing faucets with multi-waterway switching, and constant temperature water mixing faucets. The above products can basically meet the bathing needs of most users in the market. However, with the continuous improvement of consumption levels, users' requirements for bathing quality are also increasing year by year. Simple multi-functional water outlets and constant temperature water outlets can no longer meet user needs. Users are beginning to tend to pursue more upscale life enjoyment. In terms of bathing, mineral baths and floral baths have been promoted. However, the above-mentioned various bathing methods of adding bath agents usually put the bath agents in the bathtub in advance before each washing, which reduces the user experience. In addition, the bathtub also has the problem of occupying a large area, which is less practical for scenes where the bathroom area itself is not spacious. Therefore, the current bath faucets are poor in overall integration and cannot meet the user's multi-functional bathing needs.

[0060] To this end, the utility model proposes a multifunctional thermostatic faucet with a moisturizing and comfortable bathing function, which is specifically a faucet product that integrates a replaceable filter element, multiple water channel switching, and constant water temperature. Users can choose a variety of water outlet methods according to their actual bathing needs, and choose a constant water outlet temperature and water outlet flow rate. In different water outlet methods, they can further choose functional water or ordinary water that has been filtered through a filter element, wherein the functional water that has been filtered through a filter element can also have skin beautifying, skin cleansing, moisturizing, and pharmacological effects. Therefore, compared with other faucet products on the market, the bathing faucet proposed by the utility model can realize the multifunctional integration of the bathing faucet and meet the user's high-quality bathing needs.

[0061] Please refer to the following Figure 1-10 The present invention describes a bathing faucet according to an embodiment of the present invention.

[0062] refer to Figure 1As shown, the bathing faucet 100 of the embodiment of the utility model may include a thermostatic valve 10, a water circuit switching mechanism 20 and a functional component 21, wherein the water inlet end of the thermostatic valve 10 is connected to the cold water inlet pipe and the hot water inlet pipe respectively, and the thermostatic valve 10 is used to mix the cold water entering the cold water inlet pipe and the hot water entering the hot water inlet pipe to obtain mixed water, and perform constant temperature control on the mixed water. The water circuit switching mechanism 20 has a first water circuit and a second water circuit, the water inlets of the first water circuit and the second water circuit are connected to the water outlet end of the thermostatic valve 10, and the water outlets of the first water circuit and the second water circuit are used to connect to an external water outlet interface, wherein the first water circuit is used to provide functional water, and the second water circuit is used to provide ordinary water. The functional component 21 is arranged in the first water circuit to process the water in the first water circuit to obtain functional water.

[0063] Specifically, the bathing faucet 100 of the embodiment of the utility model can perform thermostatic adjustment on the temperature of the mixed water through the thermostatic valve 10, so as to adjust the temperature of the mixed water to the target temperature set by the user (such as 40-50°C). Specifically, the hot water inlet pipe can be connected to the hot water outlet of the heating water heater, and the thermostatic valve 10 is connected to the outlet of the hot water inlet pipe and the outlet of the cold water pipe. For example, the thermostatic valve 10 in this embodiment is a three-end valve, the first end of which is connected to the outlet of the hot water inlet pipe, the second end of which is connected to the outlet of the cold water inlet pipe, and the third end of which is the thermostatic outlet of the mixed water, and the target outlet water temperature is the user preset temperature (i.e., the above-mentioned target temperature).

[0064] It should be noted that the water outlet constant temperature method implemented by the thermostatic valve 10 in this embodiment adopts the physical characteristics of the mechanical thermostatic valve core, and controls the mixing ratio of cold and hot water through the mechanical thermostatic valve core, thereby adjusting the water outlet temperature to the user's preset temperature. Among them, the valve core material of the thermostatic valve 10 may include paraffin and / or memory alloy. The valve core material in this embodiment is sensitive to temperature changes. When it senses changes in ambient temperature, its own volume changes with the ambient temperature, thereby controlling the mixing ratio of cold and hot water.

[0065] Specifically, a highly sensitive memory alloy valve core can be set at the water outlet position of the third end of the thermostatic valve 10. The user can rotate the temperature adjustment device on the thermostatic valve 10 to set the target temperature of the mixed water, such as setting it to 45°C. When the mixed temperature of cold and hot water exceeds 45°C or is lower than 45°C, the memory alloy valve core changes its volume by stretching and contracting after sensing the temperature, so as to change the hot water and cold water flow at the first and second ends of the thermostatic valve 10, thereby adjusting the outlet temperature of the mixed water at the third end to the target temperature of 45°C, so that the bathing faucet of this embodiment can solve the problem of the mixed water being hot and cold during the user's bathing process, and it can realize the constant temperature regulation of the mixed water, thereby improving the user experience.

[0066] The water circuit switching mechanism 20 in this embodiment can switch the flow direction of the mixed water at the water outlet of the thermostatic valve 10 to provide ordinary water or functional water to the user. The water circuit switching mechanism 20 in this embodiment is provided with a first water circuit and a second water circuit, wherein the first water circuit and the second water circuit are both connected to the thermostatic valve 10, and the user can adjust the water circuit switching mechanism 20 to switch the mixed water at the water outlet of the thermostatic valve 10 to the first water circuit, or to the second water circuit. When switching to the first water circuit, the functional component 21 provided on the first water circuit can filter the mixed water after constant temperature to obtain functional water, and output the functional water to the external water outlet interface for the user to use; when switching to the second water circuit, the second water circuit can directly output the mixed water (i.e., ordinary water) after constant temperature to the external water outlet interface for the user to use.

[0067] refer to Figure 2 As shown, the bathing faucet 100 of the embodiment of the utility model may further include a flow regulating valve 30. The flow regulating valve 30 in this embodiment is arranged between the thermostatic valve 10 and the waterway switching mechanism 20, and the flow regulating valve 30 is used to regulate the flow of the mixed water.

[0068] In some examples, the bath faucet 100 also includes a flow adjustment knob 120, which is connected to a flow adjustment valve core 109 of a flow control valve 30. For example, the flow adjustment knob 120 can drive the flow adjustment valve core 109 to move, thereby adjusting the flow of mixed water.

[0069] like Figure 3 As shown, the flow regulating valve 30 is arranged at the water outlet of the thermostatic valve 10. When the user needs the bathing faucet 100 to provide mixed water with a larger flow or a smaller flow, the flow rate of the mixed water can be adjusted by adjusting the valve of the flow regulating valve 30 to meet the user's bathing needs of adjusting the water flow rate.

[0070] refer to Figure 4 As shown, the waterway switching mechanism 20 of the embodiment of the utility model may further include a two-way waterway switching valve 22 and a one-way check valve 23 in addition to the functional component 21. The water inlet end of the two-way waterway switching valve 22 is connected to the water outlet end of the flow regulating 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. The one-way check valve 23 is arranged in the first waterway and after the functional component 21. The one-way check valve 23 is used to prevent the functional water from flowing back.

[0071] like Figure 3As shown, the two-way waterway switching valve 22 has two water outlets, wherein the first waterway is a waterway for mixed water flowing out of one water outlet of the two-way waterway switching valve 22 to flow to the functional component 21 and the one-way check valve 23, and the second waterway is a waterway for mixed water flowing out of the other water outlet of the two-way waterway switching valve 22 to flow to the water outlet of the one-way check valve 23. The first waterway from the functional component 21 to the one-way check valve 23 can provide functional water, and the second waterway directly flowing from the water outlet of the two-way waterway switching valve 22 to the water outlet of the one-way check valve 23 can provide ordinary water, that is, mixed water flowing out of the thermostatic valve 10. The one-way check valve 23 in this embodiment can prevent the functional water at the water outlet of the functional component 21 from flowing back and damaging the functional component 21.

[0072] It should be noted that, in this embodiment, the functional component 21 arranged on the first water channel may include: a water quality filter element and / or a moisturizing filter element, wherein the moisturizing filter element has an agent adding groove, and the agent adding groove is used to place at least one of moisturizers, skin beautifying agents, and pharmaceutical agents.

[0073] Specifically, the filter element in this embodiment may be a water filter element, or a skin moisturizing filter element, or a combined filter element consisting of a water filter element and a skin moisturizing filter element.

[0074] When the filter element is only a water filter element, the mixed water at the water inlet of the first waterway can be filtered by the water filter element. For example, a filter net is provided on the water filter element, and the filter net can be a water filter material such as PP cotton, KDF, MSAP (scaling inhibitor material) that can filter mud, suspended matter, remove residual chlorine, and remove scale in the water. In this embodiment, the mixed water can be purified by the use of the water filter element to meet the user's demand for water purification.

[0075] When the filter element is only a moisturizing filter element, the mixed water at the water inlet of the first waterway can be converted through the moisturizing filter element to obtain functional water with a moisturizing function. For example, the moisturizing filter element has an agent addition slot, in which moisturizers, skin beautifying agents, skin cleansing agents, pharmaceutical agents, mineral agents, etc. can be placed. Specifically, the above-mentioned agent packages can be placed in the agent addition slot. When the mixed water at the water inlet of the first waterway flows to the agent addition slot, the above-mentioned agents can be mixed to obtain the corresponding functional water, and output to the external water outlet interface through the one-way check valve 23 for user use, thereby meeting the user's needs for healthy bathing and improving the user experience. It should be noted that this description is only a possible specific method of obtaining functional water, and the method of obtaining functional water in this embodiment is not specifically limited here.

[0076] When the filter element is a combined filter element, a moisturizing filter element can be set below the water quality filter element. After the mixed water at the water inlet of the first water channel is filtered through the water quality filter element, it is mixed with agents through the moisturizing filter element to obtain functional water with moisturizing function. In this way, the effects of healthy bathing such as skin beautification, skin cleansing, and pharmacology can be achieved on the basis of water quality filtration.

[0077] As an example, see Figure 3 As shown, when the user needs to use ordinary water, the two-way waterway switching valve 22 can be switched to allow the water inlet of the second waterway to flow into the mixed water after 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 outputs it to the external water outlet interface for the user to use. When the user needs to use functional water, the two-way waterway switching valve 22 can be switched to allow the water inlet of the first waterway to flow into the mixed water after constant temperature, and the mixed water flows to the water quality filter element or the moisturizing filter element or the combined filter element obtained by combining the water quality filter element and the moisturizing filter element, and is filtered by the filter element to obtain functional water, and then the functional water is output to the water outlet end of the one-way check valve 23, and output to the external water outlet interface for the user to use.

[0078] refer to Figure 5 and Figure 6 As shown, the bathing faucet 100 of the embodiment of the utility model may also include a three-way waterway switching valve 40. Figure 5 As shown, the three-way waterway switching valve 40 can be connected between the flow regulating valve 30 and the two-way waterway switching valve 22, or, as shown in FIG. Figure 6 As shown, it is connected between the water outlets of the first water channel, the second water channel and the external water outlet interface, that is, between the water outlet end of the water channel switching mechanism 20 and the external water outlet interface.

[0079] The external water outlet interface may include a top shower outlet interface 41, a hand shower outlet interface 42, and a lower water outlet interface 43. Specifically, the three-way waterway switching valve 40 has three water outlets. Figure 3 As shown, the three water outlets can be connected to the top spray shower outlet interface 41, the hand-held shower outlet interface 42 and the lower water outlet interface 43 respectively.

[0080] In one embodiment of the present utility model, when the three-way water circuit switching valve 40 is connected between the water outlets of the first water circuit, the second water circuit and the external water outlet interface, the water inlet end of the three-way water circuit switching valve 40 is connected to the water outlets of the first water circuit and the second water circuit, and the three water outlet ends of the three-way water circuit switching valve 40 are used to correspondingly connect to the overhead shower water outlet interface 41, the handheld shower water outlet interface 42 and the lower water outlet interface 43.

[0081] When the three-way water circuit switching valve 40 is connected between the flow regulating valve 30 and the two-way water circuit switching valve 22, the water inlet end of the three-way water circuit switching valve 40 is connected to the water outlet end of the flow regulating valve 30, and two of the three water outlet ends of the three-way water circuit switching valve 40 are used to correspondingly connect to the top spray shower water outlet interface 41 and the lower water outlet interface 43, and the other of the three water outlet ends of the three-way water circuit switching valve 40 is used to connect to the handheld shower water outlet interface 42.

[0082] In this embodiment, the filter element can be combined with any one, two or all of the water paths corresponding to the top spray shower outlet interface 41, the handheld shower outlet interface 42 or the lower water outlet interface 43 to achieve different combinations of water outlet modes to meet the user's usage needs.

[0083] Specifically, when the user requires that each water outlet interface can be applied to filtered functional water, such as Figure 3 As shown, the water inlet of the three-way waterway switching valve 40 can be connected to the water outlet of the waterway switching mechanism 20, or the water outlets of the first waterway and the second waterway, and then the three water outlets of the three-way waterway switching valve 40 can be respectively connected to the top shower outlet interface 41, the hand shower outlet interface 42 and the lower water outlet interface 43. In this way, each water outlet interface can output functional water to meet the user's usage needs.

[0084] Specifically, when the user needs all water outlets to output ordinary water, it is only necessary to switch the water circuit switching mechanism 20, that is, switch the two-way water circuit switching valve 22, so that the water inlet of the second water circuit flows into the mixed water, and the mixed water flows to the three-way water circuit switching valve 40, and the user can obtain the mixed water through each water outlet. Similarly, when the user needs all water outlets to output functional water, it is only necessary to switch the water circuit switching mechanism 20, that is, switch the two-way water circuit switching valve 22, so that the water inlet of the first water circuit flows into the mixed water, and the mixed water flows to the functional component 21 and the one-way check valve 23, and then flows into the three-way water circuit switching valve 40, and the user then rotates the three-way water circuit switching valve 40 to the corresponding water outlet to obtain functional water through the water outlet. It should be noted that the installation method of the three-way water circuit switching valve 40 that can obtain functional water for all three water outlets will increase the output waterway of the functional water, and the waterway inflection points will increase, which will bring a certain head loss, and then cause the flow rate of the water outlet interface to decrease. Therefore, the three-way waterway switching valve 40 can also be installed in the following manner.

[0085] Specifically, in order to avoid water head loss in the water path, the filter element may be combined with one or two of the water outlet interfaces, for example, it may be combined with the hand-held showerhead water outlet interface 42 .

[0086] refer to Figure 7As shown, when the user only needs to obtain functional water through the hand-held shower water outlet interface 42, the water inlet end of the three-way waterway switching valve 40 can be connected to the water outlet end of the flow regulating valve 30, and then the water outlet end of the three-way waterway switching valve 40 corresponding to the hand-held shower water outlet interface 42 is connected to the water inlet end of the waterway switching mechanism 20, and the remaining water outlet ends of the three-way waterway switching valve 40 are directly connected to the corresponding water outlet interfaces, and then the hand-held shower water outlet interface 42 is connected to the water outlets of the first waterway and the second waterway. When the user obtains functional water through the hand-held shower water outlet interface 42, the three-way waterway switching valve 40 can be switched so that the water outlet end corresponding to the hand-held shower water outlet interface 42 in the three-way waterway switching valve 40 outputs mixed water to the two-way waterway switching valve 22, and after filtering through the filter element in the first waterway, functional water is obtained, and then the functional water is output to the hand-held shower water outlet interface 42, so that the user can obtain functional water through the hand-held shower water outlet interface 42.

[0087] Of course, the user can also obtain ordinary water from the hand-held showerhead water outlet interface 42 through the two-way waterway switching valve 22. Specifically, when the user obtains ordinary water through the hand-held showerhead water outlet interface 42, the three-way waterway switching valve 40 can be switched so that the water outlet end corresponding to the hand-held showerhead water outlet interface 42 in the three-way waterway switching valve 40 outputs mixed water to the two-way waterway switching valve 22, and the two-way waterway switching valve 22 is adjusted to the second waterway to output the mixed water to the hand-held showerhead water outlet interface 42 through the second waterway, so that the user can obtain ordinary water through the hand-held showerhead water outlet interface 42.

[0088] In addition, the user can directly obtain ordinary water from the top spray shower water outlet interface 41 and the lower water outlet interface 43. Specifically, the user can switch the three-way water circuit switching valve 40 so that the water outlet corresponding to the top spray shower water outlet interface 41 in the three-way water circuit switching valve 40 outputs mixed water to the top spray shower water outlet interface 41, so that the user can directly obtain ordinary water through the top spray shower water outlet interface 41. Similarly, the user can switch the three-way water circuit switching valve 40 so that the water outlet corresponding to the lower water outlet interface 43 in the three-way water circuit switching valve 40 outputs mixed water to the lower water outlet interface 43, so that the user can directly obtain ordinary water through the lower water outlet interface 43 to meet daily use needs.

[0089] In this embodiment, different water channel combinations can be realized through the three-way water channel switching valve 40 and the water channel switching mechanism 20, thereby realizing different water outlet modes, thereby making the bath faucet of the embodiment of the utility model have the function of multi-water channel switching.

[0090] refer to Figure 8 As shown, the bathing faucet 100 in this embodiment may further include a monitoring component 50, and the monitoring component 50 is used to monitor the flow rate and / or temperature of the mixed water.

[0091] Specifically, Figure 3 or Figure 7 As shown, the monitoring component 50 may include: a flow sensor 51, a temperature sensor 52, a controller 53, a display screen 54 and a power supply 55, wherein the flow sensor 51 is used to detect the flow signal of the mixed water, and the temperature sensor 52 is used to detect the temperature signal of the mixed water; the controller 53 is connected to the flow sensor 51 and the temperature sensor 52 respectively, the controller 53 is used to receive the flow signal and the temperature signal, and send a display control signal according to the flow signal and the temperature signal; the display screen 54 is connected to the controller 53, the display screen 54 is used to receive the display control signal, and display the temperature and flow according to the display control signal; the power supply 55 is used to supply power to the flow sensor 51, the temperature sensor 52, the controller 53 and the display screen 54.

[0092] Specifically, the bath faucet 100 may be provided with a flow sensor 51 and a temperature sensor 52, which may be specifically provided at the water outlet of the flow regulating valve 30 to detect the flow rate and temperature of the mixed water at the water outlet. The above sensors may send the respectively detected flow value and temperature value to the controller 53, which is provided on the circuit board of the bath faucet 100. After receiving the flow value and temperature value, the controller 53 sends a display control signal to the display screen 54 to display the current flow rate and temperature value of the mixed water through the display screen 54. After the user knows the current flow rate and temperature value of the mixed water through the display screen 54, the user may adjust the temperature adjustment device of the thermostatic valve 10 according to actual needs to adjust the target temperature, and adjust the flow regulating valve 30 to adjust the current mixed water flow rate to meet the current bathing needs of the user.

[0093] In this embodiment, the mixed water flow and temperature are detected by sensors, and the flow and temperature are displayed on the display screen 54, so that the user can adjust the parameters according to actual needs, thereby improving the interactive experience between the user and the product and improving the user's bathing quality.

[0094] It should be noted that Figure 3 and Figure 7 In the figure, only the power supply 55 is shown to supply power to the controller 53, and the remaining electronic components such as the flow sensor 51, the temperature sensor 52 and the display screen 54 also need to be powered by the power supply 55. However, since the number of electronic components is small, the power supply 55 only needs to provide a current of several tens of milliamperes.

[0095] The power supply 55 in this embodiment may include at least one of a dry cell, a storage battery, and a water flow drive motor 551, wherein the water flow drive motor 551 is arranged between the thermostatic valve 10 and the flow regulating valve 30, and the water flow drive motor 551 includes an electric energy output terminal, wherein when the water flow drive motor 551 is running, the rotor of the water flow drive motor 551 cuts the magnetic stator of the water flow drive motor 551 to generate electric energy, and outputs the electric energy through the electric energy output terminal.

[0096] Specifically, the power supply 55 can be a dry cell with a disposable service life, or a rechargeable storage battery, or a water flow drive motor 551. The water flow drive 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 using the bathing faucet 100, the water pressure is usually low, and the water flow is small and the water cannot be pressed out. For this problem, in this embodiment, a water flow drive motor 551 can be set between the thermostatic valve 10 and the flow regulating valve 30, and the water pressure is controlled by the drive motor to meet the user's use needs. Its second function is that when it is operating normally, the rotor in the water flow drive motor 551 cuts the stator in the motor to generate electromagnetic induction and generate current, and then outputs the current to various electronic devices through the power output terminal to meet the power supply needs of various electronic devices, while saving energy consumption, and avoiding the use of external power supplies in the humid environment of the bathroom and other ways associated with strong electricity, ensuring the absolute safety of users' electricity use.

[0097] refer to Figure 3 or Figure 7 As shown, the monitoring component 50 may also include a timer 56. The timer 56 is connected to the controller 53, and the timer 56 is used to time the use time of the bath faucet 100; wherein the controller 53 is also used to control the display screen 54 to issue a prompt message to replace the functional component 21 when the use time is greater than a first preset threshold value and / or the amount of water flowing through the functional component 21 is greater than a second preset threshold value.

[0098] Specifically, the controller 53 can control the timer 56 according to the received flow signal. In order to prevent the filter element from losing its effect after long-term use, the use time of the filter element can be timed. Specifically, another flow sensor can be set on the first waterway, such as another flow sensor between the functional component 21 and the one-way check valve 23, or another flow sensor can be set on the water outlet of the one-way check valve 23. When the other flow sensor detects the flow signal, the flow signal can be sent to the controller 23. After receiving the flow signal, the controller 23 can determine that the first waterway is outputting functional water, and control the timer 56 to count. When the controller does not detect the flow signal transmitted by the other flow sensor, the control timer 56 stops counting, thereby counting the use time of the filter element during this period of time and storing it in the cache. When the user uses the functional water again, the controller continues to store the use time of the current filter element, and adds the use time of the current filter element to the use time in the previous cache, until the accumulated use time is greater than the first preset threshold (such as 30h), the control display screen 54 sends a prompt message to replace the functional component 21. At the same time, the controller 53 can also calculate the water flow of the functional component 21 according to the flow signal of another flow sensor. When the water flow is greater than a second preset threshold (such as 30 cubic meters), the controller 53 can control the display screen 54 to issue a prompt message to replace the functional component 21.

[0099] refer to Figure 3 As shown, as a specific example, the multi-functions of the bath faucet in the utility model are explained.

[0100] Specifically, hot and cold water can enter the product through the cold water inlet pipe and the hot water inlet pipe in the user's home, mix in the thermostatic valve 10, and then enter the flow regulating valve 30, and then enter the two-way water channel switching valve 22. If the valve core of the two-way water channel switching valve 22 is rotated to select the ordinary water channel outlet, the ordinary water channel, that is, the second water channel, directly enters the valve core of the three-way water channel switching valve 40 without passing through the filter element, and the terminal water outlet mode is determined by the rotation gear position of the valve core, such as overhead shower outlet, handheld shower outlet or bottom water outlet; if the valve core of the two-way water channel switching valve 22 is rotated to select the functional water channel outlet, the functional water channel, that is, the first water channel, enters the valve core of the three-way water channel switching valve 40 through the filter element, and the terminal water outlet mode is determined by the rotation gear position of the valve core.

[0101] refer to Figure 7 As shown, as another specific example, the multi-functions of the bath faucet in the utility model are explained.

[0102] Specifically, hot and cold water can enter the product through the cold water inlet pipe and the hot water inlet pipe in the user's home, mix in the thermostatic valve 10, and then enter the flow regulating valve 30, and then enter the valve core of the three-way water channel switching valve 40. At this time, if the valve core is rotated to select switching the top spray shower water outlet and the bottom water outlet, the water channel can directly discharge water through the external top spray shower and the bottom water outlet interface; if the hand-held shower water outlet is selected, the water channel will enter the valve core of the two-way water channel switching valve 22. At this time, if the valve core is rotated to select the ordinary water channel, that is, the second water channel water outlet, the water channel will be directly output from the hand-held shower interface without passing through the filter core; if the valve core is rotated to select the functional water channel, that is, the first water channel water outlet, the water channel will output functional water from the hand-held shower interface after passing through the filter core.

[0103] Furthermore, in order to more clearly describe the bathing faucet 100 according to the embodiment of the present utility model. Figure 9-12 The overall structural diagram and waterway cross-sectional diagram of a bathing faucet combining a filter element with one or two of the water outlet interfaces are shown.

[0105] For example, the two-way waterway switching valve core 113 is movably disposed in the filter element pipeline 112. When the two-way waterway switching valve core 113 is in a certain position, the water inlet end of the two-way waterway switching valve 22 is connected to one of the water outlet ends, thereby selecting the first waterway. When the two-way waterway switching valve core 113 is in another position, the water inlet end of the two-way waterway switching valve 22 is connected to the other water outlet end, thereby selecting the second waterway. The structure is simple and easy to implement.

[0106] In some examples, the bath faucet 100 also includes a two-way waterway switching knob 123, which is connected to the two-way waterway switching valve core 113. For example, the two-way waterway switching knob 123 drives the two-way waterway switching valve core 113 to move, thereby selecting the first waterway or the second waterway.

[0107] like Fig. 9 and Fig.12 As shown, in some examples, the functional component 21 is installed on the filter element pipeline 112, and the functional component 21 includes a filter element upper shell 114 and a filter element lower cover 117. The filter element lower cover 117 is arranged at the lower end of the filter element upper shell 114 and the filter element lower cover 117 cooperates with the filter element pipeline 112 to define a filter element chamber.

[0108] Furthermore, the functional component 21 further includes a filter housing 115 and a water-dividing conversion element 116. The filter housing 115 is disposed in the filter upper shell 114, and the water-dividing conversion element 116 cooperates with the lower end of the filter housing 115 and the filter lower cover 117. The water-dividing conversion element 116 can achieve a water-dividing effect, thereby dividing the water inlet and the water outlet of the functional component 21.

[0109] In some examples, the three-way waterway switching valve 40 includes a water distribution pipeline 110 and a three-way waterway switching valve core 111. The water inlet end and three water outlet ends of the three-way waterway switching valve 40 are formed on the water distribution pipeline 110. The three-way waterway switching valve core 111 is arranged in the water distribution pipeline 110 so that the water inlet end of the three-way waterway switching valve 40 can be switchably connected to its three water outlet ends.

[0110] For example, the three-way waterway switching valve core 111 can be movably arranged in the water distribution pipeline 110. When the three-way waterway switching valve core 111 is in a certain position, the water inlet end of the three-way waterway switching valve 40 is connected with the first water outlet end. When the three-way waterway switching valve core 111 is in another position, the water inlet end of the three-way waterway switching valve 40 is connected with the second water outlet end. When the three-way waterway switching valve core 111 is in another position, the water inlet end of the three-way waterway switching valve 40 is connected with the third water outlet end. The structure is simple and easy to implement.

[0111] In some examples, the bath faucet 100 also includes a three-way waterway switching knob 121, which is connected to the three-way waterway switching valve core 111. For example, the three-way waterway switching knob 121 drives the three-way waterway switching valve core 111 to move, thereby selecting the three water outlet ends of the three-way waterway switching valve 40.

[0112] like Figure 9-11 As shown, the bathing faucet 100 also includes a hot water inlet connector 101 and a cold water inlet connector 102. The hot water inlet connector 101 is suitable for connecting to a hot water inlet pipe to receive hot water, and the cold water inlet connector 102 is suitable for connecting to a cold water inlet pipe to receive cold water.

[0113] Furthermore, the bathing faucet 100 further includes a water inlet pipe 104, which is respectively connected to the hot water inlet joint 101, the cold water inlet joint 102 and the water inlet end of the thermostatic valve 10. The hot water entering the water inlet pipe 104 from the hot water inlet joint 101 is mixed with the cold water entering the water inlet pipe 104 from the cold water inlet joint 102, and the temperature of the mixed water is adjusted by the thermostatic valve core 106.

[0114] In some examples, both the hot water inlet joint 101 and the cold water inlet joint 102 are provided with anti-water cross-flow check valves 103 to prevent the hot water flowing into the water inlet pipe 104 from flowing back from the hot water inlet joint 101 to the hot water inlet pipe, and to prevent the cold water flowing into the water inlet pipe 104 from flowing back from the cold water inlet joint 102 to the cold water inlet pipe.

[0115] Fig.10 As shown, in some examples, the water inlet pipeline 104 has a first interface 1041, a second interface 1042 and a third interface 1043, the first interface 1041, the second interface 1042 and the third interface 1043 are interconnected, the hot water inlet connector 101 is arranged at the first interface 1041, the cold water inlet connector 102 is arranged at the second interface 1042, and the thermostatic valve 10 is arranged in the third interface 1043, so that the water inlet end of the thermostatic valve 10 is connected to the cold water inlet pipe and the hot water inlet pipe respectively.

[0116] Among them, the first interface 1041 can be set at one end of the water inlet pipe 104 in the length direction, and the second interface 1042 and the third interface 1043 can be set at the other end of the water inlet pipe 104 in the length direction. The hot water entering the water inlet pipe 104 from the first interface 1041 and the cold water entering the water inlet pipe 104 from the second interface 1042 can both flow toward the third interface 1043, thereby entering the thermostatic valve 10 through the water inlet end of the thermostatic valve 10, and the hot water and the cold water are mixed through the thermostatic valve core 106 to adjust the water temperature, and then flow out from the water outlet end of the thermostatic valve 10.

[0117] In some examples, the water inlet pipe 104 also has a fourth interface 1044 and a fifth interface 1045, and the fourth interface 1044 and the fifth interface 1045 are interconnected, the fourth interface 1044 is connected to the flow regulating valve 30, and the fifth interface 1045 is connected to the outlet end of the thermostatic valve, and the fifth interface 1045 is suitable for connecting to a three-way waterway switching valve 40 or a two-way waterway switching valve 22. The mixed water flowing out from the outlet end of the thermostatic valve 10 can flow toward the fifth interface 1045, and then enter the three-way waterway switching valve 40 or the two-way waterway switching valve 22. In addition, in this process, the mixed water can flow through the flow regulating valve 30 at the fourth interface 1044, and the flow rate of the mixed water is adjusted by the flow adjustment knob 120.

[0118] In some examples, the thermostatic valve 10 is installed on the water inlet pipe 104, and the thermostatic valve 10 includes a thermostatic valve mixing base 105 and a thermostatic valve core 106, and the thermostatic valve core 106 is arranged on the thermostatic valve mixing base 105; the thermostatic valve 10 also includes a thermostatic valve core fixing plate 107, and the thermostatic valve core fixing plate 107 is mounted on the thermostatic valve core 106 and cooperates with the thermostatic valve mixing base 105, with a simple structure and easy assembly and disassembly.

[0119] In some examples, the bath faucet 100 also includes a base 118 and a thermostatic valve adjustment seat 108. The thermostatic valve adjustment seat 108 is disposed on the base 118, and the thermostatic valve 10 is installed on the thermostatic valve adjustment seat 108. By setting the thermostatic valve adjustment seat 108, the thermostatic valve 10 can be limited, and the position of the thermostatic valve 10 can also be adjusted.

[0121] Among them, the material of the thermostatic valve core 106 can be paraffin and / or memory alloy that is sensitive to temperature changes, so that when it senses the temperature change of the mixed water, its own volume changes with the ambient temperature, thereby controlling the mixing ratio of cold and hot water and achieving temperature regulation of the mixed water.

[0122] In this embodiment, the bath faucet further includes a thermostatic adjustment knob 119, which is connected to the thermostatic valve core 106. For example, the thermostatic adjustment knob 119 can be connected to the thermostatic valve core 106 by a connector, one end of the connector is connected to the thermostatic valve core 106 and the other end is connected to the thermostatic adjustment knob 119. The temperature of the mixed water can be actively adjusted to the required temperature by rotating the thermostatic adjustment knob 119.

If the hand-held shower outlet interface 42 needs to output functional water, the three-way water channel switching valve core 111 can be switched to the water distribution pipeline 110, and the mixed water is switched to the first water channel through the filter element pipeline 112 and the two-way water channel switching valve core 113, and the functional water is obtained at the hand-held shower outlet interface 42. Of course, the mixed water can also be switched to the second water channel through the two-way water channel switching valve core 113, and ordinary water can be obtained at the hand-held shower outlet interface 42. Among them, the three-way water channel switching valve core 111 is connected to the three-way water channel switching knob 121, and the two-way water channel switching valve core 113 is connected to the two-way water channel switching knob 123.
