However, in some public places, the faucet handle is in contact with different people for a long time, which is easy to breed bacteria. In addition, it needs to be touched before and after washing hands, causing the washed hands to come into contact with the handle again when turning off the faucet, which is not very hygienic. Utility Model Content

[0003] Based on the above problems, the purpose of the present utility model is to provide a faucet with a novel control method, which is safe and hygienic when used and suitable for public areas.

[0004] In response to the above problems, the following technical solutions are provided: a faucet, comprising a main body, a water inlet connector provided on the side wall of the main body, a push / bounce valve core provided in the main body, a first valve cavity and a second valve cavity provided in sequence from one end of the main body to the other end, the first valve cavity opening provided with a first thread, and the second valve cavity opening provided with a second thread; the push / bounce valve core is placed in the second valve cavity and screwed together with the second thread, and the valve stem passes through the first valve cavity to the outside of the main body; a water outlet nozzle is screwed onto the first thread, and a slide is provided at the center of the water outlet nozzle for the valve stem to slide out; the bottom of the second valve cavity is connected to the first valve cavity through a return water channel, the water inlet connector is connected to the side wall of the second valve cavity, the bottom of the push / bounce valve core is sealed against the bottom of the second valve cavity, water flows from the side wall of the push / bounce valve core and is guided out from the rear end of the push / bounce valve core to the return water channel, and then is discharged from the water outlet nozzle through the first valve cavity.

[0005] The present invention is further configured such that the inner diameter of the first valve cavity is larger than that of the second valve cavity; a secondary cavity is provided at the other end of the main body, a plugging cover is provided at the opening of the secondary cavity, the bottom of the secondary cavity is connected to the bottom of the second valve cavity; the return water channel is located outside the second valve cavity to connect the secondary cavity and the first valve cavity.

[0006] The present invention is further configured such that there are a plurality of return water channels, which are opened at intervals along the circumferential direction of the main body.

[0007] The present invention is further configured such that the first valve cavity is further provided with an inner stop shoulder, and the inner stop shoulder is located behind the first thread; the rear end of the water outlet nozzle is sealed against the inner stop shoulder.

[0008] The utility model is further configured such that the water outlet nozzle is a bubbler.

[0009] The present invention is further configured such that the axial length of the valve stem outside the water outlet is not less than its pressing stroke.

[0010] The present invention is further configured such that the valve stem further includes a touch head located at an end thereof, and the touch head is in a water drop shape.

[0011] The present invention is further configured such that the touch head is threadably connected to the valve stem.

[0012] The present invention is further configured such that a connecting thread is provided at one end of the water inlet connector away from the main body.

[0013] The utility model is further configured such that the outer wall of the push / bounce valve core is provided with a first sealing ring that is sealed and adapted to the inner wall of the second valve cavity; and the rear end of the push / bounce valve core is provided with a second sealing ring that is sealed and adapted to the bottom of the second valve cavity.

[0014] The utility model is further configured such that the push / bounce valve core is an existing valve core (such as CN201920181224.5, CN201821705254.3, CN201921069072.6). When working, the water flow is unblocked by pressing the valve stem once, and the water flow is cut off by pressing the valve stem again.

[0015] Beneficial effects of the utility model:

[0016] 1. The push / pop valve core is installed upside down, and its valve stem extends outward through the center of the water outlet. When in use, water is discharged by pressing the valve stem at the center of the water outlet. During the water discharge process, hands are cleaned and the valve stem in the center of the water outlet is flushed and cleaned by the water flow. After the hands are cleaned, the valve stem is pressed again to stop the water flow, avoiding the secondary contamination of the hands by the valve stem, which has the advantages of safety and hygiene. Since the push / pop valve core is installed upside down, in order to avoid the water pressure acting on the pressing direction of the valve stem affecting its operation, the side of the push / pop valve core needs to be defined as the inlet and the bottom as the outlet. Therefore, the water flowing out of the rear end of the push / pop valve core needs to be guided to the first valve chamber and then discharged from the water outlet in conjunction with the return water channel.

[0017] 2. The inner diameter of the first valve chamber is larger than that of the second valve chamber. The return channel only needs to be drilled to achieve the connection between the auxiliary chamber and the first valve chamber. It also provides space for the placement and installation of the push / bounce valve core. The plug cover is screwed and fixed to the auxiliary chamber opening.

[0018] 3. The cross-sectional size of the return channel directly affects the outer diameter of the entire main body. Therefore, while ensuring that the outer diameter does not increase as much as possible and that the flow supply is met, the flow rate is maximized by increasing the number of return channels.

[0019] 4. The touch head is preferably made of stainless steel, which can effectively prevent rust. At the same time, the water drop shape structure can effectively improve the pressing feel and avoid sanitary dead corners when flushing with water. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] refer to Figures 1 to 9 ,like Figures 1 to 9The faucet shown in the figure includes a main body 10, a water inlet connector 20 is provided on the side wall of the main body 10, a push / pop valve core 30 is provided in the main body 10, and a first valve cavity 11 and a second valve cavity 12 are provided in sequence from one end of the main body 10 to the other end. The first valve cavity 11 has a first thread 111 at the cavity opening, and the second valve cavity 12 has a second thread 121 at the cavity opening; the push / pop valve core 30 is placed in the second valve cavity 12 and screwed into the second thread 121, and the valve stem 31 passes through the first valve cavity 11 to the main body 1 0 outside; the first thread 111 is screwed with a water outlet 40, and the center of the water outlet 40 is provided with a slide 41 for the valve stem 31 to slide out; the bottom of the second valve cavity 12 is communicated with the first valve cavity 11 through the return channel 13, and the water inlet connector 20 is communicated with the side wall of the second valve cavity 12. The bottom of the push / bounce valve core 30 is sealed against the bottom of the second valve cavity 12, and the water flows from the side wall of the push / bounce valve core 30 and is guided from the rear end of the push / bounce valve core 30 to the return channel 13, and then is discharged from the water outlet 40 through the first valve cavity 11.

[0032] In the above structure, the push / bounce valve core 30 is installed inverted, and its valve stem 31 extends outward through the center of the water outlet 40; when in use, water is discharged by pressing the valve stem 31 at the center of the water outlet 40. During the water discharge process, the hands are cleaned and the valve stem 31 in the center of the water outlet 40 can be flushed and cleaned by the water flow. After the hands are cleaned, the water can be stopped by pressing the valve stem 31 again, which avoids the secondary contamination of the hands by the valve stem 31, and has the advantages of safety and hygiene. Since the push / bounce valve core 30 is installed inverted, in order to avoid the water pressure acting on the pressing direction of the valve stem 31 to affect its operation, it is necessary to define the side of the push / bounce valve core 30 as the inlet 32 ​​and the bottom as the outlet 33. Therefore, it is necessary to cooperate with the return water channel 13 to guide the water flow flowing out of the rear end of the push / bounce valve core 30 to the first valve chamber 11 and then discharge it from the water outlet 40.

[0033] In this embodiment, the inner diameter of the first valve chamber 11 is larger than that of the second valve chamber 12; a secondary chamber 14 is provided at the other end of the main body 10, and a plugging cover 50 is provided at the opening of the secondary chamber 14, and the bottom of the secondary chamber 14 is connected to the bottom of the second valve chamber 12; the return water channel 13 is located outside the second valve chamber 12 to connect the secondary chamber 14 and the first valve chamber 11.

[0034] In the above structure, the inner diameter of the first valve chamber 11 is larger than that of the second valve chamber 12, and the return channel 13 only needs to be drilled to achieve the conduction between the sub-chamber 14 and the first valve chamber 11; at the same time, it also provides space for the placement and installation of the push / bounce valve core 30; the plug cover 50 is screwed and fixed to the cavity mouth of the sub-chamber 14.

[0035] In this embodiment, there are multiple water return channels 13 , which are spaced apart along the circumferential direction of the main body 10 .

[0036] In the above structure, the cross-sectional size of the return channel 13 directly affects the outer diameter of the entire main body 10. Therefore, while ensuring that the outer diameter does not increase as much as possible and satisfying the flow supply, the flow rate is maximized by increasing the number of return channels 13.

[0037] In this embodiment, the first valve cavity 11 is further provided with an inner stop shoulder 112 , and the inner stop shoulder 112 is located behind the first thread 111 ; the rear end of the water outlet nozzle 40 is sealed against the inner stop shoulder 112 .

[0038] In the above structure, the inner shoulder 112 abuts against the water spout 40 when the water spout 40 is installed, providing positioning for the water spout 40 while ensuring sealing.

[0039] In this embodiment, the water outlet 40 is a bubbler.

[0040] In the above structure, a foaming effect is achieved when water is discharged.

[0041] In this embodiment, the axial length of the valve stem 31 outside the water outlet 40 is not less than its pressing stroke.

[0042] In the above structure, it is avoided that the valve stem 31 cannot be pressed into place and cannot be locked in the on state or the off state due to the extension stroke being too short.

[0043] In this embodiment, the valve stem 31 further includes a touch head 34 at its end, and the touch head 34 is in a teardrop shape.

[0044] In the above structure, the touch head 34 is preferably made of stainless steel, which can effectively prevent rust. At the same time, the teardrop-shaped structure can effectively improve the pressing feel and avoid sanitary dead corners when flushing with water.

[0045] In this embodiment, the touch head 34 is threadedly engaged with the valve stem 31 .

[0046] The above structure facilitates installation and adaptation with the water outlet nozzle 40 .

[0047] In this embodiment, a connecting thread 21 is provided at one end of the water inlet connector 20 away from the main body 10 .

[0048] In the above structure, the connecting thread 21 is used to connect to the pre-buried joint on the wall or the pipe.

[0049] In this embodiment, the outer wall of the push / bounce valve core 30 is provided with a first sealing ring 35 that is sealed and adapted to the inner wall of the cavity opening of the second valve cavity 12; the rear end of the push / bounce valve core 30 is provided with a second sealing ring 36 that is sealed and adapted to the bottom of the second valve cavity 12.

[0050] In the above structure, water leakage between the water inlet position and the water outlet position of the push / bounce valve core 30 can be avoided.

[0051] In this embodiment, the press / bounce valve core 30 is an existing valve core (such as CN201920181224.5, CN201821705254.3, CN201921069072.6). When working, the water flow is unblocked by pressing the valve stem 31 once, and the water flow is cut off by pressing the valve stem 31 again.

[0052] In the above structure, in order to ensure that the length of the valve stem 31 can meet the extension requirement, the above patented extended valve stem 31 can be adaptively extended.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications based on the above assumptions should also be regarded as within the scope of protection of the present invention.
