[0047] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0048] Reference Figures 1 to 9 This embodiment provides a faucet with a spray function, including a housing 1 having an inlet 11 and an outlet 12, the housing 1 also having a spray nozzle 13, and the faucet with a spray function further includes:

[0049] Liquid storage container 2, which can be connected to spray nozzle 13;

[0050] And a spray assembly 3 is provided inside the housing 1. The spray assembly 3 can generate gas and form a negative pressure at the spray nozzle 13 to draw out the solution in the liquid storage container 2 and atomize it into a spray by the gas.

[0051] The water outlet 12 and the spray nozzle 13 are independent of each other. The solution stored in the liquid storage container 2 can be a skin care solution, such as a skin care product with moisturizing and whitening functions. When using the product, the consumer can wash their face through the water outlet 12. After washing, the water outlet 12 is closed, and the spray component 3 is activated. The solution in the liquid storage container 2 can then be sprayed out from the spray nozzle 13 to achieve the skin care function for the face.

[0052] Therefore, the faucet in this embodiment, by adding a liquid storage container 2 and a spray assembly 3, adds a spray function to the existing conventional faucet, which only has a washing function. This allows consumers to conveniently perform skincare or other skincare activities after washing, enriching the product's functionality and user experience. Simultaneously, the spray assembly 3 uses a negative pressure created by gas to draw the solution out of the liquid storage container 2 and then atomizes the solution into a spray by blowing the liquid with gas. This not only reduces clogging during dispensing and extends its service life, but also allows for a wider range of applicable liquid concentrations and facilitates manufacturing.

[0053] In specific implementation methods, such as Figure 2 and Figure 3 As shown, the spray assembly 3 includes a connector 31 and an air pump 32. The connector 31 has an independently arranged airflow channel 311 and a liquid flow channel 312. The connector 31 has a negative pressure zone 313 near the spray nozzle 13. Both the airflow channel 311 and the liquid flow channel 312 are connected to the negative pressure zone 313. The outlet end of the air pump 32 is connected to the airflow channel 311, and the liquid storage container 2 is connected to the liquid flow channel 312. After the air pump 32 is turned on, the high-speed gas generated by the air pump 32 is sprayed out of the spray nozzle 13 along the airflow channel 311, and a negative pressure is formed at the position of the negative pressure zone 313. The solution in the liquid storage container 2 is drawn out to the negative pressure zone 313 under the action of pressure difference. Due to the high-speed flow of the gas, the solution is blown into fine particles, thus forming a spray effect.

[0054] The entire atomizing component has a simple structure. In this method, the outlet size of the liquid flow channel 312 can be made to about 1 mm. Compared with the existing ultrasonic atomization method, which requires the spray hole to be made very small (generally a few micrometers), the size of the liquid output port in this embodiment is relatively large, so it is not easy to clog when dispensing liquid. The size of the atomized particles is slightly larger than that of ultrasonic atomization, which can avoid the atomized particles being too small and being inhaled into the lungs of consumers for a long time, thus avoiding harm to their health. In addition, the solution is atomized by using high-speed airflow to disperse it, so that solutions with a certain viscosity can also be atomized better, resulting in better atomization effect and a wider range of applicable liquid concentrations.

[0055] In practical applications, in order to create a better negative pressure effect in the negative pressure zone 313 when the gas is ejected, the part of the airflow channel 311 near the negative pressure zone 313 is arranged around the outer periphery of the liquid flow channel 312.

[0056] Thus, in the area near the negative pressure zone 313, the liquid flow channel 312 and the air flow channel 311 are arranged in concentric circles, with the air flow channel 311 located on the outer ring. Due to the high gas flow rate, when the gas is ejected in a ring in the negative pressure zone 313, it will carry away the air in the middle of the ring air flow, making the negative pressure zone 313 produce a better negative pressure effect, which is more conducive to sucking out the solution in the liquid storage container 2.

[0057] Furthermore, for easier processing and installation, such as Figures 3 to 7 As shown, the connector 31 includes a connecting body 314 and a nozzle 315. The connecting body 314 has a first airflow channel 3111 and a first liquid flow channel 3121, which are independently arranged. The nozzle 315 is sealed and inserted between the first end of the connecting body 314 and the spray nozzle 13. The nozzle 315 has a second airflow channel 3112 and a second liquid flow channel 3122, which are independently arranged. The second airflow channel 3112 surrounds the outer periphery of the second liquid flow channel 3122. The second airflow channel 3112 communicates with the first airflow channel 3111 through a side hole 3113 on the nozzle 315, and the second liquid flow channel 3122 communicates with the first liquid flow channel 3121. The first airflow channel 3111, the second airflow channel 3112, and the side hole 3113 constitute the airflow channel 311, and the first liquid flow channel 3121 and the second liquid flow channel 3122 constitute the liquid flow channel 312. A negative pressure zone 313 is formed on the nozzle 315.

[0058] In this way, the connecting body 314 and the nozzle 315 can be processed separately, which makes it easier to manufacture the liquid flow channel 312 and air flow channel 311 mentioned above. The structure is also simpler and the channel integration is higher. After the connecting body 314 and the nozzle 315 are processed, the nozzle 315 can be directly sealed and connected between the housing 1 and the connecting body 314, which is simple and convenient.

[0059] To facilitate the assembly and fixation of the nozzle 315, a flange 3151 protrudes outward from the middle of the nozzle 315. The first end of the connecting body 314 forms a stepped hole 3141 with an enlarged diameter that communicates with the first liquid flow channel 3121. The two ends of the nozzle 315 are respectively inserted into the first liquid flow channel 3121 and the spray nozzle 13. The two ends of the flange 3151 abut against the shoulder of the stepped hole 3141 and the inner wall of the housing 1, respectively. A first sealing ring 316 is sandwiched between the nozzle 315 and the connecting body 314.

[0060] It is understood that the stepped hole 3141 connects to the first end face of the connecting body 314, and the stepped hole 3141 also connects to the first airflow channel 3111; a first sealing ring 316 is provided between the first end of the nozzle 315 (i.e. the end near the connecting body 314) and the hole wall of the first liquid flow channel 3121, and between the flange 3151 and the hole wall of the stepped hole 3141. For example, an annular sealing groove is provided at the first end of the nozzle 315, and a first sealing ring 316 is embedded in the annular sealing groove to ensure the sealing at the junction of the first liquid flow channel 3121 and the second liquid flow channel 3122; an extension ring is formed on the end face of the flange 3151, and another first sealing ring 316 is sleeved on the extension ring to ensure the sealing at the junction of the first airflow channel 3111 and the side hole 3113; at this time, the end of the extension ring abuts against the shoulder of the stepped hole 3141, and the first sealing ring 316 can be in close contact with the hole wall of the stepped hole 3141. The airflow first enters the inner area of ​​the extension ring through the first airflow channel 3111, and then flows into the second airflow channel 3112 through the side hole 3113.

[0061] Generally, a limiting ring 14 is also provided on the inner wall of the housing 1. The limiting ring 14 surrounds the outer periphery of the spray nozzle 13 and can position the nozzle 315. During installation, after the first sealing ring 316 is fitted onto the first end of the nozzle 315 and the flange 3151 (specifically the extension ring), the first end of the nozzle 315 is first inserted into the connecting body 314, so that the flange 3151 (specifically the extension ring) abuts against the shoulder of the stepped hole 3141; then the connecting body 314 and the nozzle 315 are installed together in the housing 1, so that the second end of the nozzle 315 (i.e. the end near the spray nozzle 13, with the first end and the second end of the nozzle 315 arranged opposite to each other) is inserted into the spray nozzle 13, and part of the flange 3151 is embedded in the limiting ring 14 and abuts against the inner wall of the housing 1; the nozzle 315 is limited by the shoulder of the stepped hole 3141 and the inner wall of the housing 1, and the nozzle 315 is clamped and fixed in the housing 1 and the connecting body 314, making assembly more convenient.

[0062] As a preferred option, such as Figure 4 and Figure 7 As shown, the diameter of the portion of the second liquid flow channel 3122 near the first liquid flow channel 3121 is larger than the diameter of the portion near the negative pressure zone 313, and the outer diameter of the portion of the second airflow channel 3112 near the side hole 3113 is larger than the outer diameter of the portion near the negative pressure zone 313. A groove 3152 is provided at the end of the nozzle 315, and the width of the groove 3152 is larger than the outer diameter of the second airflow channel 3112 near the negative pressure zone 313. The groove 3152 constitutes the negative pressure zone 313.

[0063] During operation, the gas passes through the first airflow channel 3111 and the side hole 3113, then enters the larger second airflow channel 3112, and is then ejected through the smaller second airflow channel 3112. The gas flow path is as follows: Figure 4 As shown by line L1 in the diagram; the liquid is first drawn into the larger second liquid flow channel 3122 through the first liquid flow channel 3121, and then drawn out through the smaller-diameter second liquid flow channel 3122. The flow path of the liquid is as follows. Figure 4 As shown by line L2 in the diagram. This not only facilitates the manufacturing of the nozzle 315, but also reduces pipe resistance (i.e., the resistance of the pipe wall to the fluid), making it easier for gas and liquid to be ejected. The specific dimensions of each channel depend on the needs, and this invention does not limit them.

[0064] It can be understood that the nozzle 315 is generally cylindrical, and the axis of the second liquid flow channel 3122 is the center line of this cylindrical structure. The larger outer diameter portion of the second airflow channel 3112 is located inside the nozzle 315 corresponding to the flange 3151. The aforementioned side hole 3113 is opened on the end face of the flange 3151 near the first end of the nozzle 315 to facilitate connection between the first airflow channel 3111 and the second airflow channel 3112. Generally, the axis of the nozzle 315 is inclined upward so that when the user uses the spray function for skin care, the spray can be sprayed obliquely upward and directly onto the user's face, making it more comfortable to use. At this time, for ease of assembly, the first end of the connecting body 314 is also inclined upward, and the part of the housing 1 corresponding to the nozzle 315 is also adapted to the inclination direction of the nozzle 315. For example, the side of the housing 1 protrudes outward to form a triangular prism structure, and the spray nozzle 13 is opened on the inclined surface of the triangular prism structure.

[0065] Furthermore, to prevent air leakage when gas is introduced into the airflow channel 311 from the outlet end of the air pump 32, such as... Figure 3 and Figure 6 As shown, the second end of the connecting body 314 is provided with an annular slot 3142, which surrounds the outer periphery of the first liquid flow channel 3121. An annular seal 321 is sleeved on the outer side of the outlet end of the air pump 32, and the annular seal 321 is embedded in the annular slot 3142.

[0066] The second end of the connecting body 314 is positioned opposite to its first end, and its second end is directly opposite the outlet end of the air pump 32. The first airflow channel 3111 and the first liquid flow channel 3121 in the connecting body 314 are independent of each other and can be configured according to… Figure 6 The two are arranged side by side as shown in the figure, and the annular slot 3142 here can be arranged according to Figure 6The connection between the annular seal 321 and the first liquid flow channel 3121 shown in the diagram may or may not be connected, depending on the actual processing requirements. The annular seal 321 can be made of relatively soft seals such as rubber. Its elasticity can ensure the sealing between the outlet end of the air pump 32 and the first liquid flow channel 3121, ensuring working efficiency and convenient installation.

[0067] Furthermore, in order to ensure that the solution in the storage container 2 can still be smoothly drawn out after multiple uses of the spray function of the faucet, a through hole 21 is provided on the storage container 2 to communicate with the outside atmosphere. This ensures that after the gas forms a negative pressure in the negative pressure zone 313, the solution can be smoothly drawn out under the pressure difference between the outside atmosphere and the negative pressure, thus avoiding the phenomenon that a vacuum will form in the storage container 2 after multiple uses, which would prevent the solution from being smoothly drawn out.

[0068] More specifically, the installation position of the liquid storage container 2 and the setting position of the through hole 21 can be achieved using the following two installation methods:

[0069] First installation method: Refer to... Figure 3 and Figure 8 The liquid storage container 2 is a bottle structure with an open end on the first end face. The liquid storage container 2 is located on the top surface of the shell 1, with its open end facing downwards. Its open end passes through the top surface of the shell 1 and is detachably and sealed to the liquid flow channel 312. A through hole 21 is opened on the second end face of the liquid storage container 2, and a hollow column 22 extends into the interior of the liquid storage container 2 at the through hole 21.

[0070] It is understood that the first and second end faces of the liquid storage container 2 are arranged opposite each other, and the hollow column 22 can connect the through hole 21 and the interior of the liquid storage container 2. During installation, after the solution is added to the liquid storage container 2 through the open end, the liquid storage container 2 is inverted so that its open end faces downwards, and it passes through the top surface of the shell 1 and connects with the liquid flow channel 312. Due to the presence of the hollow column 22, when the liquid storage container 2 is placed upright (i.e., its open end faces upwards) for liquid addition, as long as the liquid level does not exceed the height of the hollow column 22, leakage can be avoided during liquid addition, and the structure is simple.

[0071] The second installation method: The liquid storage container 2 is a bottle structure with an open end on the first end face. The liquid storage container 2 is placed on the bottom surface of the shell 1 with its open end facing upwards, and its open end passes through the bottom surface of the shell 1 and is detachably and sealed to the liquid flow channel 312. The through hole 21 is opened on the first end face of the liquid storage container 2.

[0072] In this structure, the first and second end faces of the liquid storage container 2 are also arranged opposite to each other, and the through hole 21 is generally arranged side by side with the open end. During installation, after adding the solution into the liquid storage container 2 through the open end, the liquid storage container 2 remains upright, and its open end is simply passed through the bottom surface of the shell 1 and then connected to the liquid flow channel 312, which is simple to operate. Generally, to prevent overflow from the through hole 21 when a large amount of liquid is added to the liquid storage container 2, it can be arranged as follows: Figure 9 The tube 23 extends outward from the through hole 21 as shown in the figure. Alternatively, a straw structure that communicates with the outside atmosphere can be sealed and inserted at the through hole 21 as needed.

[0073] Regarding the two installation methods mentioned above, in practical applications, the entire faucet is generally installed according to... Figure 3 As shown in the diagram, the outlet 12 is located on the bottom surface of the housing 1. Therefore, whether the liquid storage container 2 is installed on the top surface of the housing 1 in the first installation method, so that it is on a different side from the outlet 12, or on the bottom surface of the housing 1 in the second installation method, so that it is on the same side as the outlet 12, can be determined according to actual needs.

[0074] It should be noted that when the liquid storage container 2 is placed upright using the second installation method described above, no solution will automatically overflow from the spray nozzle 13 when the air pump 32 is turned off. However, when the liquid storage container 2 is placed upside down using the first installation method described above, a small amount of solution may automatically overflow under the influence of gravity when the air pump 32 is turned off. This can generally be avoided by taking measures such as designing the liquid flow channel 312 in the nozzle 315 to be smaller and the pipe resistance to be relatively larger; or by positioning the spray nozzle 13 at a height higher than the liquid level in the liquid storage container 2 to prevent automatic overflow.

[0075] The connection between the liquid storage container 2 and the liquid flow channel 312 (specifically, the connection with the first liquid flow channel 3121) can be achieved using the following two connection methods:

[0076] First connection method: Refer to Figure 3 and Figure 6 A mounting ring 3143 communicating with the liquid flow channel 312 is formed on the connector 31 (specifically on the connecting body 314). The open end of the liquid storage container 2 is threadedly connected to the mounting ring 3143, and a second sealing ring 24 is sandwiched between the open end and the mounting ring 3143. Generally, the second sealing ring 24 is fitted onto the open end of the liquid storage container 2, and the outer wall of the open end is threadedly connected to the inner wall of the mounting ring 3143. This ensures a seal while allowing for easy disassembly and assembly of the liquid storage container 2 to replenish the liquid.

[0077] The second connection method: The open end of the liquid storage container 2 is connected to the connector 31 (specifically the connecting body 314) via a flexible hose. It can be understood that this method involves corresponding pipe fittings on the open end and the connecting body 314 for connection to the flexible hose; simultaneously, the liquid storage container 2 is also connected and fixed to the shell 1 via corresponding fasteners (such as screws, snap fasteners, etc.).

[0078] Of the two connection methods mentioned above, the first method is simpler to process and install; the second method allows for greater flexibility in the placement of the liquid storage container 2, which can be placed near the front of the housing 1 (i.e., near the spray nozzle 13) or at the rear of the housing 1 (i.e., away from the spray nozzle 13). The specific connection method used can be determined based on the product's appearance and processing requirements.

[0079] Of course, other methods can be used for the liquid storage container 2, its installation location, and its connection with the liquid flow channel 312. This embodiment is only an example.

[0080] Furthermore, to facilitate the control of the air pump 32 and the water outlet 12, such as Figures 1 to 3 As shown, an electric control switch 33 is also provided on the housing 1, which can control the air pump 32 to turn on or off. The water inlet 11 and the water outlet 12 are connected by a water pipe 4, and a switch valve 41 is provided on the water pipe 4.

[0081] When the user needs to wash, the switch valve 41 opens; when the user stops using water, the switch valve 41 closes. When the user needs to use the spray function, the electronic control switch 33 opens; after skincare is complete, the electronic control switch 33 closes. The electronic control switch 33 can be, for example, a push-button switch, or other types of switches as needed. The electronic control scheme controls the air pump 32 to generate a high-speed airflow that sprays the solution out in a mist manner, making operation more convenient. A power supply component 34 for supplying power to the air pump 32 is also provided inside the housing 1. The electronic control switch 33 is electrically connected to both the power supply component 34 and the air pump 32 to control the power supply from the power supply component 34 to the air pump 32.

[0082] In addition, the power supply component 34, the air pump 32, and the connecting body 314 will also be connected and fixed to the housing 1 through corresponding fixing structures, such as in this embodiment. Figure 2 and Figure 3 As shown, an annular frame structure 15 is fixed inside the housing 1. The power supply component 34 and the air pump 32 can be embedded in the frame structure 15 for fixation. The outlet end of the air pump 32 is fitted with an annular seal 321 and protrudes through the side opening of the frame structure 15. The annular frame at the side opening also serves to circumferentially press the annular seal 321. The connecting body 314 can be connected and fixed to the housing 1 using corresponding supports and screws.

[0083] Furthermore, for ease of processing and installation, such as Figure 2 As shown, the housing 1 includes a shell body 16 with a top opening and a cover plate 17 detachably connected to the open end of the shell body 16. For example, the shell body 16 and the cover plate 17 can be connected and fixed by fasteners (such as screws, snap fasteners, etc.). The spray assembly 3 is located inside the shell body 16, and the electronic control switch 33 is located on the cover plate 17. For a more aesthetically pleasing appearance, a decorative panel 18 is also provided on the cover plate 17, and corresponding mounting holes are provided on the decorative panel 18 at the positions corresponding to the electronic control switch 33. When the liquid storage container 2 is located on the top surface of the housing 1, corresponding mounting holes are also provided on the cover plate 17 and the decorative panel 18 to allow the open end of the liquid storage container 2 to pass through.

[0084] Generally, the housing 16 includes two interconnected and vertically arranged horizontal and vertical housings. Both the horizontal and vertical housings are rectangular structures. The water inlet 11 is located at the bottom of the vertical housing, and the switch valve 41 is located on the side of the vertical housing. The water outlet 12 is located at the bottom of the horizontal housing, the spray nozzle 13 is located on the side of the horizontal housing, and the spray assembly 3 is located inside the horizontal housing.

[0085] Furthermore, taking the solution in storage container 2 as an example of a skin care lotion, the specific working process of the faucet in this embodiment is as follows:

[0086] When the user needs to wash up, the switch valve 41 is opened, and water flows through the water pipe 4 and out of the water outlet 12, allowing the user to wash. After washing up, the switch valve 41 is closed, and the water outlet 12 is shut off. Then, the electronic control switch 33 is turned on, starting the air pump 32. The high-speed gas output from the outlet of the air pump 32 passes through the first airflow channel 3111, the side hole 3113, and the second airflow channel 3112 in sequence, and is then sprayed out as a ring-shaped airflow, creating a negative pressure in the negative pressure zone 313. Under the pressure difference between the external atmospheric pressure and the negative pressure, the skin care liquid in the storage container 2 is drawn out through the first liquid flow channel 3121 and the second liquid flow channel 3122 into the negative pressure zone 313. In the negative pressure zone 313, the skin care liquid is blown into fine particles by the high-speed airflow, thus forming a spray effect and being sprayed out from the spray nozzle 13, which can be used to care for the user's face, achieving whitening and moisturizing effects. After the user has finished skin care, the electronic control switch 33 is turned off, and the air pump 32 stops working.

[0087] The faucet now includes an additional liquid storage container 2, which can hold moisturizing and whitening skincare products. Using a dual-channel negative pressure suction method combining airflow channel 311 and liquid flow channel 312, and employing high-speed gas generated by air pump 32 to create localized negative pressure, the skincare liquid is sprayed out in the form of particles. This effectively integrates the spray function into the faucet, enriching the product's functionality and experience. It allows consumers to conveniently perform skincare after washing, and the sprayed skincare liquid is more convenient to use and provides better skincare results.

[0088] The above are merely illustrative embodiments of the present invention and are not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention.
