Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings.

Referring to fig. 1 to 9, the present embodiment provides a faucet with a spraying function, including a housing 1 having a water inlet 11 and a water outlet 12, the housing 1 further having a spraying outlet 13, the faucet with a spraying function further including:

the liquid storage container 2 can be communicated with the spray opening 13;

and a spray assembly 3 arranged in the shell 1, wherein the spray assembly 3 can generate gas and form negative pressure at a spray opening 13 so as to suck the solution in the liquid storage container 2 out and atomize the solution into spray by the gas.

The water outlet 12 and the spray outlet 13 are independent from each other, and the solution stored in the liquid storage container 2 may be a skin care lotion, for example, some skin care products having functions of moisturizing, whitening and the like. When the face-care toilet is used by a consumer, the user can wash the face through the water outlet 12, after the washing is finished, the water outlet 12 is closed, the spraying assembly 3 is started, and the solution in the liquid storage container 2 can be sprayed out from the spraying port 13 in a spraying mode, so that the face-care function is realized.

Therefore, the faucet in the embodiment has the advantages that by adding the liquid storage container 2 and the spraying assembly 3, on the basis that the conventional faucet only has a washing function, the spraying function is added, a consumer can conveniently perform corresponding skin care after washing, and the like, so that the functions of products and the user experience are enriched. Simultaneously, spraying assembly 3 utilizes the mode of gaseous formation negative pressure to the solution suction in with stock solution container 2 to utilize the mode that gaseous blowing liquid becomes the spraying with solution atomizing, not only difficult jam when going out liquid, life is longer, and the concentration range of the liquid that is suitable for moreover is wider, and processing manufacturing is more convenient.

In a specific implementation, as shown in fig. 2 and 3, the spray assembly 3 comprises a connecting member 31 and an air pump 32, the connecting member 31 has an air flow channel 311 and a liquid flow channel 312 therein, which are independent of each other, the connecting member 31 has a negative pressure region 313 at a position adjacent to the spray outlet 13, and both the air flow channel 311 and the liquid flow channel 312 are communicated with the negative pressure region 313. The outlet end of the air pump 32 communicates with an air flow passage 311, and the liquid reservoir 2 can communicate with a liquid flow passage 312. After the air pump 32 is started, high-speed air generated by the air pump 32 is sprayed out of the spray opening 13 along the air flow channel 311, negative pressure is formed at the position of the negative pressure area 313, and the solution in the liquid storage container 2 is sucked out of the negative pressure area 313 under the action of pressure difference; due to the high-speed flow of the gas, the solution can be blown into fine particles, and then the spraying effect is formed.

The whole atomization assembly is simple in structure, in addition, the size of the outlet end of the liquid flow channel 312 can be about 1mm in the mode, and compared with the mode that the spray holes are required to be made to be extremely small (generally, a few micrometers) in the prior art, the size of the liquid outlet port in the embodiment is relatively large, so that the liquid outlet is not easy to block; the size of the formed atomized particles is slightly larger than that of the atomized particles in an ultrasonic atomization mode, so that the harm to the health of a user caused by the fact that the atomized particles are too small and are inhaled into the lung of the user for a long time can be avoided; in addition, the solution is atomized by using a mode of blowing the solution by high-speed airflow, so that the solution with certain viscosity can be better atomized, the atomization effect is better, and the range of the applicable liquid concentration is wider.

In practical applications, in order to form a better negative pressure effect in the negative pressure region 313 when the gas is ejected, a portion of the gas flow channel 311 near the negative pressure region 313 is surrounded on the outer periphery of the liquid flow channel 312.

Thus, in the area close to the negative pressure region 313, the liquid flow channel 312 and the gas flow channel 311 are arranged in a concentric circle, the gas flow channel 311 is located at the outer ring, and since the gas flow rate is high, the gas can take away the air in the middle of the annular gas flow when the negative pressure region 313 is ejected in an annular shape, so that the negative pressure region 313 generates a better negative pressure effect, and the solution in the liquid storage container 2 can be sucked out more favorably.

Further, for easier manufacture and installation, as shown in fig. 3 to 7, the connection member 31 includes a connection body 314 and a spray head 315, the connection body 314 has a first air flow passage 3111 and a first liquid flow passage 3121 formed therein independently of each other, and the spray head 315 is sealingly interposed between the first end portion of the connection body 314 and the spray opening 13. The spray head 315 is provided with a second air flow passage 3112 and a second liquid flow passage 3122 which are independent of each other, and the second air flow passage 3112 is enclosed in the periphery of the second liquid flow passage 3122. The second gas flow passage 3112 communicates with the first gas flow passage 3111 through a side hole 3113 in the shower head 315, and the second liquid flow passage 3122 communicates with the first liquid flow passage 3121. The first air flow passage 3111, the second air flow passage 3112 and the side hole 3113 constitute the air flow passage 311, the first liquid flow passage 3121 and the second liquid flow passage 3122 constitute the liquid flow passage 312, and the negative pressure region 313 is formed on the shower head 315.

Thus, the connecting body 314 and the nozzle 315 can be processed separately, so that the flow channel 312 and the gas flow channel 311 can be formed by the process more conveniently, the structure is simpler, the integration level of the channels is higher, and after the connecting body 314 and the nozzle 315 are processed, the nozzle 315 can be directly and hermetically connected between the shell 1 and the connecting body 314, which is simple and convenient.

Generally, to facilitate the assembly and fixation of the nozzle 315, a flange 3151 is protruded from the middle of the nozzle 315, and a stepped hole 3141 having an increased diameter is formed at the first end of the connecting body 314 to communicate with the first fluid passage 3121. Both ends of the nozzle 315 are respectively inserted into the first fluid passage 3121 and the spray opening 13, both ends of the flange 3151 respectively abut against the shoulder of the stepped hole 3141 and the inner wall of the housing 1, and a first sealing ring 316 is interposed between the nozzle 315 and the connecting body 314.

It is understood that the stepped hole 3141 communicates with the first end surface of the connecting body 314, and the stepped hole 3141 also communicates with the first air flow passage 3111; first sealing rings 316 are interposed between a first end portion (i.e., the end near the connecting body 314) of the spray head 315 and the wall of the first fluid passage 3121, and between the flange 3151 and the wall of the stepped bore 3141. For example, an annular sealing groove is formed at the first end of the nozzle 315, and one of the first sealing rings 316 is embedded in the annular sealing groove to ensure the sealing property at the joint of the first fluid passage 3121 and the second fluid passage 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 performance of the joint of the first air flow 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, the first sealing ring 316 can be tightly contacted with the wall of the stepped hole 3141, and the gas flow enters the inner region of the extension ring through the first gas flow channel 3111 and then flows into the second gas flow channel 3112 through the side hole 3113.

A limiting ring 14 is generally disposed on the inner wall of the housing 1, and the limiting ring 14 is disposed around the outer circumference of the spray opening 13 to position the spray head 315. During installation, after the first end portion of the nozzle 315 and the flange 3151 (specifically, the extension ring) are sleeved with the first sealing ring 316, the first end portion of the nozzle 315 is 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 spray head 315 are installed together in the housing 1, so that the second end portion of the spray head 315 (i.e. the end portion close to the spray opening 13, and the first end portion and the second end portion of the spray head 315 are oppositely arranged) is inserted into the spray opening 13, and part of the flange 3151 is embedded in the limiting ring 14 and is abutted 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, so that the assembly is more convenient.

Preferably, as shown in fig. 4 and 7, the portion of the second liquid flow passage 3122 adjacent to the first liquid flow passage 3121 has a larger diameter than the portion thereof adjacent to the negative pressure region 313, and the portion of the second gas flow passage 3112 adjacent to the side hole 3113 has a larger outer diameter than the portion thereof adjacent to the negative pressure region 313. A groove 3152 is formed at an end of the nozzle 315, a groove width of the groove 3152 is larger than an outer diameter of the second air flow passage 3112 near the negative pressure region 313, and the groove 3152 constitutes the negative pressure region 313.

In operation, the gas flows through the first gas channel 3111 and the side hole 3113, enters the second gas channel 3112 with a larger size, and then is ejected through the second gas channel 3112 with a smaller size, and the flow path of the gas is shown by line L1 in fig. 4; the liquid is first sucked into the second liquid flow passage 3122 with a larger size through the first liquid flow passage 3121, and then is sucked out through the second liquid flow passage 3122 with a smaller aperture, and the flow path of the liquid is shown by a line L2 in fig. 4. Not only can the processing and manufacturing of the spray head 315 be facilitated, but also the pipe resistance (i.e. the resistance of the pipe wall to the fluid) can be reduced, and the spraying of the gas and the liquid can be facilitated. The size of each channel is determined according to the requirement, and the utility model is not limited to this.

It will be appreciated that the nozzle 315 is generally cylindrical, the axis of the second fluid passage 3122 is the centerline of the cylindrical structure, the larger outer diameter portion of the second fluid passage 3112 is disposed within the nozzle 315 at a location corresponding to the flange 3151, and the side opening 3113 is disposed on the end surface of the flange 3151 near the first end of the nozzle 315 to facilitate communication between the first fluid passage 3111 and the second fluid passage 3112. Generally, the axis of the nozzle 315 is inclined upward, so that when a user uses the spraying function to care skin, the spray can be sprayed obliquely upward to face the user, and the user feels more comfortable. In this case, for the convenience of assembly, the first end of the connecting body 314 is also inclined upward, and the portion of the housing 1 corresponding to the nozzle 315 is also adapted to the inclined direction of the nozzle 315, for example, the side of the housing 1 protrudes outward to form a triangular prism structure, and the spray opening 13 is opened on the inclined surface of the triangular prism structure.

Further, in order to avoid the air leakage phenomenon when the outlet end of the air pump 32 introduces air into the air flow channel 311, as shown in fig. 3 and 6, the second end of the connecting body 314 is provided with an annular insertion groove 3142, the annular insertion groove 3142 surrounds the periphery of the first liquid flow channel 3121, an annular sealing member 321 is sleeved outside the outlet end of the air pump 32, and the annular sealing member 321 is embedded in the annular insertion groove 3142.

The second end of the connecting body 314 is opposite to the first end thereof, and the second end thereof is opposite to the outlet end of the air pump 32. The first air channel 3111 and the first fluid channel 3121 in the connecting body 314 are independent of each other, and may be arranged in parallel according to the two shown in fig. 6, and the annular insertion groove 3142 may or may not be communicated with the first fluid channel 3121 according to the illustration in fig. 6, according to the actual processing requirement. The annular sealing member 321 may be a relatively soft sealing member such as a rubber member, and the elasticity thereof can ensure the sealing property of the butt joint between the outlet end of the air pump 32 and the first fluid passage 3121, thereby ensuring the working efficiency and facilitating the installation.

Further, in order to ensure that the solution in the liquid storage container 2 can still be smoothly sucked out after the spraying function of the faucet is used for many times, the liquid storage container 2 is provided with a through hole 21 which can be communicated with the external atmosphere, so that the solution can be smoothly sucked out under the action of the pressure difference between the external atmosphere and the negative pressure after the gas forms the negative pressure in the negative pressure region 313, and the phenomenon that the solution cannot be smoothly sucked out due to the fact that vacuum is formed in the liquid storage container 2 after the faucet is used for many times is avoided.

More specifically, the following two mounting methods can be adopted for the mounting position of the liquid storage container 2 and the arrangement position of the through hole 21:

the first installation mode: referring to fig. 3 and 8, the liquid reservoir 2 is a bottle structure having an open end at a first end, the liquid reservoir 2 is disposed on the top surface of the housing 1, the open end is disposed downward, and the open end penetrates the top surface of the housing 1 and is detachably and sealingly connected to the liquid flow channel 312. The through hole 21 is opened on the second end face of the liquid storage container 2, and extends to the inside of the liquid storage container 2 at the through hole 21 to form a hollow column 22.

It will be appreciated that the first end face and the second end face of the reservoir 2 are oppositely disposed, and the hollow post 22 can communicate the through hole 21 with the interior of the reservoir 2. When the liquid storage container 2 is installed, the solution is added into the liquid storage container 2 from the open end, and the liquid storage container 2 is inverted to enable the open end to face downwards, penetrates through the top surface of the shell 1 and then is communicated with the liquid flow channel 312. Due to the existence of the hollow column 22, when the liquid storage container 2 is placed upright (namely the open end of the liquid storage container is placed upwards) for liquid adding, as long as the liquid level does not exceed the height of the hollow column 22, liquid leakage during liquid adding can be avoided, and the structure is simple.

The second installation mode is as follows: the liquid storage container 2 is a bottle structure with an open end at a first end, the liquid storage container 2 is arranged on the bottom surface of the shell 1, the open end is placed upwards, and the open end penetrates through the bottom surface of the shell 1 and is detachably and hermetically connected with the liquid flow channel 312. The through hole 21 is opened on the first end face of the liquid storage container 2.

In this structure, the first end face and the second end face of the liquid storage container 2 are also oppositely arranged, and the through holes 21 are generally arranged side by side with the open end. During installation, after the solution is added into the liquid storage container 2 from the opening end, the liquid storage container 2 is still kept upright, and the opening end of the liquid storage container is directly penetrated through the bottom surface of the shell 1 and then communicated with the liquid flow channel 312, so that the operation is simple and convenient. In order to prevent the liquid from overflowing from the through hole 21 even when a large amount of liquid is filled into the liquid storage container 2, a tube 23 may be formed by extending outward from the through hole 21 as shown in fig. 9, or a straw structure communicating with the outside atmosphere may be inserted into the through hole 21 in a sealing manner as required.

For both of the above-described mounting arrangements, the water outlet 12 is located on the bottom surface of the housing 1, since in practice the entire faucet is generally positioned in the up-down orientation shown in fig. 3. Therefore, the liquid storage container 2 is specifically arranged on the top surface of the shell 1 according to a first installation mode so as to be located on a different side from the water outlet 12, or the liquid storage container 2 is arranged on the bottom surface of the shell 1 according to a second installation mode so as to be located on the same side as the water outlet 12, and the installation mode can be determined according to actual needs.

It should be noted that when the liquid storage container 2 is placed upright in the second installation manner, when the air pump 32 is turned off, no solution automatically overflows from the spray opening 13. When the liquid storage container 2 is placed upside down in the first installation mode, and the air pump 32 is closed, a little of solution may automatically overflow under the action of gravity; measures are generally taken to avoid this, for example, the flow passages 312 in the spray head 315 may be designed to be smaller in size and relatively larger in impedance; the spray opening 13 can be positioned higher than the liquid level of the solution in the liquid storage container 2 to prevent the liquid from overflowing automatically.

For the communication between the liquid reservoir 2 and the flow channel 312 (specifically, the communication with the first flow channel 3121), the following two connection methods can be adopted:

the first connection mode is as follows: referring to fig. 3 and 6, a mounting ring 3143 communicating with the liquid flow channel 312 is formed on the connection member 31 (specifically, on the connection body 314), the open end of the liquid reservoir 2 is screwed to the mounting ring 3143, and a second seal ring 24 is interposed between the open end and the mounting ring 3143. The second sealing ring 24 is generally fitted over the open end of the reservoir 2, and the outer wall of the open end is threadedly engaged with the inner wall of the mounting ring 3143. The liquid storage container 2 can be conveniently disassembled and assembled while sealing is guaranteed, so that liquid is supplemented.

The second connection mode is as follows: the open end of the reservoir 2 is connected to the connector 31 (specifically, the connector body 314) via a hose. It will be appreciated that in this manner corresponding fittings will be provided on the open end and the connecting body 314 for connection to a hose; meanwhile, the liquid storage container 2 is connected and fixed with the shell 1 through corresponding fixing parts (such as screws, buckles and the like).

For the two connection modes, the first connection mode is simpler and more convenient to process and install; the second connection mode can be more flexible for the position of the liquid storage container 2, and can be placed close to the front part of the shell 1 (namely, the position close to the spray opening 13) or placed at the back part of the shell 1 (namely, the position far away from the spray opening 13). Which connection mode is adopted can also be determined according to the appearance needs and the processing needs of the product.

Of course, other ways of connecting the reservoir 2 and the mounting location and the fluid channel 312 may be used, and this embodiment is merely illustrative.

Further, in order to facilitate the control of the opening and closing of the air pump 32 and the opening and closing of the water outlet 12, as shown in fig. 1 to 3, an electrically controlled switch 33 is further disposed on the housing 1, and the electrically controlled switch 33 can control the opening and closing of the air pump 32. The water inlet 11 and the water outlet 12 are connected through a water pipe 4, and a switch valve 41 is arranged on the water pipe 4.

When the user needs to wash, the on-off valve 41 is opened; when the user stops using the water, the on-off valve 41 is closed. When the user needs to use the spraying function, the electric control switch 33 is turned on, and after the skin care is finished, the electric control switch 33 is turned off. The electrically controlled switch 33 may be, for example, a push button switch, or may be another type of switch as needed. The air pump 32 is controlled by an electric control scheme to generate high-speed air flow to spray the solution in a spraying mode, so that the operation is more convenient. A power supply assembly 34 for supplying power to the air pump 32 is further disposed in the housing 1, and the electrically controlled switch 33 is electrically connected to both the power supply assembly 34 and the air pump 32, so as to control the power supply of the power supply assembly 34 to the air pump 32.

In addition, the power supply assembly 34, the air pump 32 and the connecting body 314 are further connected and fixed with the casing 1 through corresponding fixing structures, for example, in this embodiment, as shown in fig. 2 and fig. 3, an annular frame structure 15 is fixedly disposed in the casing 1, the power supply assembly 34 and the air pump 32 can be embedded in the frame structure 15 to be fixed, an outlet end of the air pump 32 is sleeved with the annular sealing member 321 and then penetrates through a side opening of the frame structure 15, and the annular frame at the side opening also plays a role in circumferentially compressing the annular sealing member 321. The connecting body 314 can be fixed to the housing 1 by means of corresponding seats and screw fittings.

Further, for convenience of manufacture and installation, as shown in fig. 2, the housing 1 includes a housing 16 with an open top, and a cover 17 detachably connected to the open end of the housing 16, for example, the housing 16 and the cover 17 can be fixed by a fixing member (e.g., a screw, a snap, etc.), the spraying assembly 3 is disposed in the housing 16, and the electric control switch 33 is disposed on the cover 17. For better appearance, a decorative panel 18 is further arranged on the cover plate 17, and corresponding mounting holes are formed in the decorative panel 18 corresponding to the positions of the electric control switches 33. When the liquid storage container 2 is arranged on the top surface of the casing 1, corresponding mounting holes are also formed on the cover plate 17 and the decorative panel 18 so as to facilitate the opening end of the liquid storage container 2 to pass through.
