Description

Technical Field

[0001] The invention relates to the technical field of bathroom products, in particular to a faucet device with a liquid bottle device. Background Art

[0002] Existing faucets generally only have a water-discharging function, and the cleaning liquid is generally used by pressing a liquid bottle alone, or the liquid bottle is installed on the faucet and the liquid bottle is pressed to discharge the liquid during use. For example, CN201651527U discloses a faucet with a liquid bottle device, which includes a faucet body, and the sides of the faucet body are respectively provided with a water outlet pipe and a control handle, and the upper part of the faucet body is provided with a press-type liquid bottle device. This faucet integrates the press-type liquid bottle device into the faucet body, which saves space and is easy to use. There is no need to purchase a cleaning liquid bottle separately, but in this method, the cleaning liquid is separated from the water outlet waterway.

[0003] At present, there is also a method of directly connecting the cleaning liquid to the water outlet waterway, and controlling the input of the cleaning liquid into the waterway through a liquid pump to achieve mixed water outlet, such as CN219471102U, a combined pull-out faucet that automatically senses the cleaning liquid, including a countertop and a faucet body arranged on the countertop, the water outlet end of the faucet body is connected and installed with a pull-out faucet, an infrared sensing shell is fixedly installed on the outer surface of the faucet body, and the surface of the infrared sensing shell is provided with a sensing liquid outlet and an infrared sensing window, and an infrared sensing sensor module is arranged inside the infrared sensing window. The technical solution of the utility model performs manual sensing through an infrared sensing sensor module, thereby automatically starting the liquid pumping motor, and then the sensing liquid outlet can flow out of the cleaning liquid. However, this method requires an additional pump body for conveying the cleaning liquid to the water outlet waterway, which is more complicated in structure and more expensive, and also requires an additional power supply for starting the pump body, which cannot be used in some environments without reserved circuits. Summary of the invention

[0004] The invention discloses a faucet device with a liquid bottle device, which has a simple structure and aims to improve the above-mentioned problems.

This solution has a simple structure, and can also realize the extraction of cleaning liquid into the water passage without the use of a pump body. It is simple to operate and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] Combination Figures 1 to 5 As shown, the present embodiment provides a faucet device with a liquid bottle 4 device, comprising a body 1, wherein a water passage is arranged in the body 1, and comprising: a liquid bottle 4 rotatably arranged outside the body 1; a venturi tube structure 2 is arranged on the water passage, and the liquid bottle 4 is provided with a connecting channel connected to the venturi tube structure 2, so as to be suitable for generating suction to the liquid bottle 4 when water flows through the venturi tube structure 2; the liquid bottle 4 is configured to be rotatable between a first angle and a second angle, when the liquid bottle 4 is at the first angle, the connecting channel is disconnected from the water passage, and when the liquid bottle 4 is rotated to the second angle, the connecting channel is connected to the water passage, so that the cleaning liquid in the liquid bottle 4 is sucked out into the water passage.

[0023] In this embodiment, the first angle and the second angle merely represent the angles between the liquid bottle and the body, and their specific values ​​are not specifically limited.

[0024] Combination Figures 1 to 3As shown, in this embodiment, the body 1 is provided with a shell, a valve core 13, a water passage, a handle, etc., and the water passage includes an inlet waterway 11 and an outlet waterway 12. The liquid bottle 4 can be connected to the inlet waterway 11 or the outlet waterway 12. In the embodiment, the liquid bottle 4 is connected to the inlet waterway 11. The inlet waterway includes a hot water pipe and a cold water pipe, and the liquid bottle 4 can be connected to the hot water pipe or the cold water pipe. In this embodiment, the liquid bottle 4 is connected to the hot water pipe. The outlet waterway 12 can be provided with a bubbler 3, which can quickly generate foam when the water mixed with the cleaning liquid flows through.

[0025] Combination Figures 3 to 5 As shown, the venturi tube can be integrated into the water inlet pipe, or it can be separately set as a module to be installed on the water inlet pipe. The venturi tube structure 2 includes an inlet 21, a diffuser 22, a contraction 23 and an outlet 24; the cross-sectional area of ​​the outlet 24 is larger than the inlet 21; the two ends of the diffuser 22 are respectively connected to the inlet 21 and the contraction 23, and its water flow cross-sectional area is larger than the inlet 21 and the contraction 23; the two ends of the contraction 23 connect the diffuser 22 and the outlet 24, and its water flow cross-sectional area gradually decreases from the diffuser 22 to the outlet 24; the diffuser 22 is provided with a liquid inlet channel 25 to connect the connecting channel. Here, the contraction 23 forms a conical structure, and the water flow cross-sectional area gradually decreases toward the outlet 24. The water flow cross-sectional area of ​​the inlet 21 and the outlet 24 is smaller than the water flow cross-sectional area of ​​the water inlet channel, so when the water flows through the inlet 21, the water flow cross-sectional area is reduced, so it is accelerated at the inlet 21, and the water flow cross-sectional area of ​​the diffuser 22 is larger than the inlet 21, and the water flow cross-sectional area of ​​the diffuser 22 is also smaller than the water inlet channel 11. The water pressure at the diffuser 22 is low, lower than the air pressure in the liquid bottle 4, so it will generate suction on the connecting pipe 6 to suck the cleaning liquid in the liquid bottle 4 into the water flow channel, and mix with the water flow before flowing out. It should be noted that the venturi tube structure 2 can be set at any position of the water flow channel.

[0026] Combination Figures 1 to 4As shown, in this embodiment, the communication channel includes a communication tube 6 disposed in the liquid bottle 4, and the communication tube 6 is suitable for communicating with the liquid inlet channel 25 when the liquid bottle 4 is at the second angle. The communication tube 6 extends into the liquid bottle 4, and one end is located at the bottom of the liquid bottle 4. The body 1 is provided with a mounting groove 14, and the liquid bottle 4 is provided with a connecting portion 42 suitable for being installed in the mounting groove 14, and the communication tube 6 is eccentrically arranged in the connecting portion 42. The connecting portion 42 can be movably connected in the mounting groove 14 by a threaded manner or a snap-fit ​​manner. The eccentrically arranged connecting tube 6 allows the nozzle of the connecting tube 6 to rotate when the liquid bottle 4 rotates as a whole, so that when the liquid bottle 4 rotates to a first angle, the nozzle of the connecting tube 6 is separated from the liquid inlet channel 25 and blocked by the sealing surface in the mounting groove 14. At this time, the channel opening of the liquid inlet channel 25 is also blocked by the plane of the liquid bottle 4 to prevent water from flowing out of the liquid inlet channel 25. When the liquid bottle 4 rotates to a second angle, the connecting tube 6 is connected to the liquid inlet channel 25, so that the suction force in the liquid inlet channel 25 can act on the connecting tube 6. It should be noted that in other embodiments, the connecting tube 6 may not be provided, and the connecting portion 42 may be directly provided at the bottom of the liquid bottle 4, so that the cleaning liquid flows out directly from the connecting portion 42. Since the connecting surface gradually increases or decreases when the connecting tube 6 is connected to the liquid inlet channel 25, in another embodiment, the liquid discharge speed may also be controlled by controlling the angle of the liquid bottle 4.

[0027] Combination Figures 2 to 4 As shown, the liquid bottle 4 is provided with a liquid replenishing port 41, and the liquid replenishing port 41 is provided with the one-way air inlet valve; specifically, the one-way air inlet valve can be set as a duckbill valve 5, and the duckbill valve 5 includes an air inlet channel 51, and an elastic sheet 52 is respectively provided on both sides of the air inlet channel 51, and the ends of the two elastic sheets 52 are connected to each other to form a V-shaped structure suitable for blocking the air inlet channel 51, and when the pressure in the liquid bottle 4 is greater than the air pressure outside the liquid bottle 4, the two elastic sheets 52 separate to open the air inlet channel 51. The duckbill valve 5 is made of rubber material. On the one hand, it is convenient to disassemble at the fluid replenishment port 41 for fluid replenishment. On the other hand, it can also achieve a relatively good sealing effect. The elastic sheet 52 is also made of rubber material. In a natural state, the ends of the two elastic sheets 52 abut against each other to form a V-shaped structure, which can close the air inlet channel 51 and prevent the cleaning liquid from flowing out of the air inlet channel 51. When the liquid bottle 4 is rotated to the second angle, the liquid inlet channel 25 generates suction on the liquid bottle 4. At this time, the air pressure in the water passage is lower than the air pressure in the liquid bottle 4. Therefore, the liquid in the liquid bottle 4 can be quickly sucked into the water passage. When the air pressure in the liquid bottle 4 is lower than the atmospheric pressure, the elastic sheet 52 is deformed under the action of the atmospheric pressure, so that the connecting channel is opened to replenish air into the liquid bottle 4.

[0028] The liquid bottle 4 of this embodiment can store commonly used cleaning liquids such as hand soap and shower gel. When in use, the connecting tube 6 in the connecting portion 42 of the liquid bottle 4 is rotated to align with the liquid inlet channel 25 of the mounting groove 14 so that it can be freely conducted. At this time, when water flows through the venturi tube structure 2 from the water passage, the water flow transitions from the small hole to the large hole to generate suction, so that the cleaning liquid in the liquid bottle 4 is sucked through the liquid inlet channel 25 and passes through the bubbler 3 or the multi-layer filter to generate foam.

[0029] In a preferred embodiment, a one-way valve is provided at the upstream end of the water passage located at the venturi tube structure 2. The one-way valve can prevent the cleaning liquid from being sucked into the upstream water source when the water flow in the water passage flows back, thus achieving a protective effect.

[0030] In this embodiment, the liquid bottle 4 can be rotated under the control of the user to control whether the liquid bottle 4 is connected to the water passage; by arranging the venturi tube structure 2 in the water passage, when the liquid bottle 4 is at the second angle, suction can be provided to the liquid bottle 4 to suck out the cleaning liquid. Through the scheme of this embodiment, the cleaning liquid can be drawn into the water passage for mixing without a pump body, and the control is convenient. When the cleaning liquid is not needed, closing the liquid bottle 4 does not affect the normal water discharge, and the overall structure is compact and not easy to damage.

[0031] It should be understood that the above are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.

[0032] The above description of the drawings used in the implementation manner only illustrates certain embodiments of the present invention and should not be regarded as limiting the scope. For ordinary technicians in this field, other related drawings can be obtained based on these drawings without paying creative work.
