Description

Technical Field

[0001] The utility model relates to the field of kitchen and bathroom, in particular to a basin faucet. Background Art

[0002] Existing hot and cold water mixing faucets usually have a valve core in the faucet, but the valve core is relatively large because it has components such as a lever, a valve plate, and a seal inside, which also causes the faucet to have to be adaptively increased in size. In order to reduce the size of the faucet, in some prior arts, a rotatable valve shaft is provided to control the opening and closing and flow of hot and cold water. However, the sealing contact between the water inlet of the valve shaft and the faucet housing is easily weakened due to wear and tear due to long-term switching. At this time, when the user rotates to close one of the water channels and only uses the other water channel, the water flow in the closed water channel is easy to flow into the water channel through the gap at the wear point, causing water leakage, affecting the water output effect of the basin faucet. Utility Model Content

[0003] The utility model provides a basin faucet, which aims to reduce the influence of water leakage on the water discharge effect of the faucet when the sealing ability of the water inlet is reduced due to wear.

[0004] To achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A basin faucet according to a first embodiment of the utility model comprises: a housing, wherein a first water inlet channel, a second water inlet channel, a water passage cavity and a water outlet channel are provided in the housing, wherein the first water inlet channel and the second water inlet channel are both connected to the same end of the water passage cavity, and the water outlet channel is connected to the other end of the water passage cavity;

[0007] a valve shaft, the valve shaft being arranged in the water passage cavity and having a first water passage hole, a second water passage hole and a water outlet hole, the water outlet hole being connected to the water outlet channel, the valve shaft being connected to the handle assembly to be driven by the handle assembly to connect or block the first water passage hole to the first water inlet channel, or to connect or block the second water passage hole to the second water inlet channel;

[0008] Wherein, a first baffle is provided on the outer peripheral wall of the valve shaft on the side facing away from the first water passage hole, and a second baffle is provided on the outer peripheral wall of the valve shaft on the side facing away from the second water passage hole.

[0009] According to the basin faucet of the embodiment of the utility model, when the first water hole or the second water hole is closed, if both sides of the first water hole or both sides of the second water hole are worn, it is impossible to achieve a good seal with the inner wall of the water cavity, and water leakage is likely to occur. By arranging the first baffle plate and the second baffle plate on the valve shaft, the baffle plate divides and isolates the outer peripheral wall between the two sides of the water hole, so that the cut-off water flow can only enter the space between one side of the water hole and the baffle plate, and cannot enter the space between the other side of the water hole and the baffle plate and leak water from the other side, that is, the water flow can only flow into the water cavity from one side of the water hole, and cannot flow water from both sides at the same time, thereby reducing the amount of water leakage by 50%, reducing the influence of water leakage on the water outlet effect.

[0015] According to some embodiments of the present utility model, the raised portion includes an arc-shaped plate and a plurality of convex ribs, and when the tooth sleeve rotates with the handle, the elastic component sequentially abuts against the plurality of convex ribs on the arc-shaped plate.

[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. 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.

[0037] refer to Figure 1 and Figure 2 Some embodiments of the utility model provide a basin faucet 1000, including a housing 100, a handle assembly 200 and a valve shaft 300. The housing 100 is provided with a first water inlet channel 110, a second water inlet channel 120, a water passage chamber 130 and a water outlet channel 140. One of the first water inlet channel 110 and the second water inlet channel 120 may be a hot water channel, and the other may be a cold water channel. The first water inlet channel 110 and the second water inlet channel 120 are both connected to the same end of the water passage chamber 130, and the water outlet channel 140 is connected to the other end of the water passage chamber 130, thereby forming a water flow channel. It can be understood that hot water and cold water can enter through the first water inlet channel 110 and the second water inlet channel 120 respectively, flow through the water chamber 130, and then flow out from the water outlet channel 140.

[0038] The handle assembly 200 is disposed in the housing 100 . Specifically, the handle assembly 200 passes through the housing 100 , with a portion of the handle assembly 200 being located inside the housing 100 and another portion of the handle assembly 200 being exposed outside the housing 100 .

[0039] The valve shaft 300 is disposed in the water passage cavity 130 and has a first water passage hole 310, a second water passage hole 320 and a water outlet hole 330. The water outlet hole 330 is connected to the water outlet channel 140. The valve shaft 300 is connected to the portion of the handle assembly 200 located in the housing 100. The handle assembly 200 can drive the valve shaft 300 to rotate around the axis of the valve shaft 300, so that the first water passage hole 310 is connected to or blocked from the first water inlet channel 110, or the second water passage hole 320 is connected to or blocked from the second water inlet channel 120. Figure 3 and Figure 4 A first baffle plate 340 is disposed on the outer wall of the valve shaft 300 on the side facing away from the first water hole 310 , and a second baffle plate 350 is disposed on the outer wall of the valve shaft 300 on the side facing away from the second water hole 320 .

[0040] refer to Figure 5 , taking the second water hole 320 blocking the second water inlet channel 120 as an example, the second water hole 320 is staggered with the second water inlet channel 120, and cold water enters the space between the valve shaft 300 and the inner wall of the water chamber 130. At this time, both sides of the second water hole 320 abut against the inner wall of the water chamber 130, so that cold water cannot enter the water chamber 130 from the second water hole 320, resulting in a poor water discharge effect. When the valve shaft 300 is used for a long time, both sides of the second water hole 320 will be worn, and at this time, cold water will enter the water chamber 130 through the second water hole 320 from the worn part. A second baffle 350 is arranged on the valve shaft 300, which can isolate the outer peripheral wall between the two sides of the second water hole 320, and can block the cold water so that it can only enter the space between one side of the second water hole 320 and the second baffle 350, and cannot enter the space between the other side and the second baffle 350. Therefore, even if the two sides of the second water hole 320 are worn, the cold water can only flow into the water cavity 130 from one side of the second water hole 320. That is, by setting the second baffle 350, the water flow rate can be reduced by 50%, thereby reducing the influence of the water flow on the water outlet effect.

[0041] It can be understood that the first baffle 340 is sealed and connected to the inner wall of the water passage chamber 130 to divide the outer peripheral walls on both sides of the first water passage hole 310 into two parts arranged circumferentially along the valve shaft 300, and the second baffle 350 is sealed and connected to the inner wall of the water passage chamber 130 to divide the outer peripheral walls on both sides of the second water passage hole 320 into two parts arranged circumferentially along the valve shaft 300, wherein the outer peripheral wall area of ​​the valve shaft 300 in any part after division is larger than the water inlet area of ​​the corresponding water inlet channel.

[0042] See also Figure 2 In some embodiments of the present invention, the axis of the valve shaft 300 is parallel to the axis of the water chamber 130. Compared with the arrangement in which the axis of the valve shaft 300 is perpendicular to the axis of the water chamber 130, the basin faucet 1000 can be prevented from increasing in size to adapt to the setting direction of the valve shaft 300, which is conducive to the miniaturization and compact design of the faucet product.

[0043] In some embodiments of the present invention, there may be multiple first baffles 340 and second baffles 350 , so as to better prevent water from flowing into the water cavity 130 from the other side of the second water hole 320 .

[0044] refer to Figures 1 to 6In some embodiments of the present invention, the handle assembly 200 includes a handle 210 and a gear sleeve 220. The gear sleeve 220 is disposed inside the housing 100. The handle 210 passes through the housing 100 and is connected to the gear sleeve 220. Part of the handle 210 is located inside the housing 100, and the other part is exposed outside the housing 100 for user operation. A gear shaft 360 is disposed on one end of the valve shaft 300 close to the handle assembly 200. The gear sleeve 220 is sleeved on the gear shaft 360 and meshed, so that the handle assembly 200 is connected to the valve shaft 300. Therefore, the user only needs to turn the handle 210 to drive the valve shaft 300 to rotate through the gear sleeve 220, thereby adjusting the water inlet of hot water and cold water.

[0045] In some embodiments of the present invention, a through slot 150 is provided on the side wall of the housing 100, and the handle 210 is inserted into the through slot 150 and connected to the toothed sleeve 220 in the housing 100. Figure 1 The through slot 150 is in the shape of an elongated strip and is arranged to extend along the circumference of the housing 100 . The handle 210 is passed through the through slot 150 to control the rotation of the gear sleeve 220 . The handle 210 can move in the through slot 150 .

[0046] In some embodiments of the utility model, an elastic component 230 is provided on one end of the tooth sleeve 220 close to the inner wall of the shell 100, and a protrusion 160 is provided on the inner wall of the shell 100 along the rotation path of the tooth sleeve 220. When the tooth sleeve 220 rotates with the handle 210, the elastic component 230 and the protrusion 160 remain in abutment, and the elastic component 230 is squeezed by the protrusion 160, constantly deforming and recovering, thereby providing a damping feel for the process of rotating the handle 210.

[0047] refer to Figure 6 and Figure 7 In some embodiments of the utility model, the raised portion 160 includes an arc-shaped plate 162 and a plurality of convex ribs 161. Specifically, the arc-shaped plate 162 is arranged inside the shell 100, and the plurality of convex ribs 161 are arranged on a side surface of the arc-shaped plate 162 close to the gear sleeve 220 along the rotation path of the gear sleeve 220. When the gear sleeve 220 rotates, the elastic component 230 abuts against the plurality of convex ribs 161 in turn, thereby being continuously squeezed and deformed, thereby providing a damping feel for the process of rotating the handle 210.

[0048] In some embodiments of the utility model, along the circumferential direction of the housing 100, the height of the plurality of ribs 161 increases from the middle of the arc plate 162 to the two end components, so that when the elastic component 230 contacts the ribs 161 at different positions, the degree of extrusion deformation is different, so the damping feel is different. Specifically, it can be set that when the handle 210 is rotated to the position with the lowest or highest water outlet temperature, the height of the rib 161 abutting against the elastic component 230 is the highest, and at other water outlet temperatures, the height of the rib 161 gradually decreases. For example, when the handle 210 is rotated to the leftmost, only cold water is in and out, and the water outlet temperature is the lowest at this time. When the handle assembly 200 is rotated to the rightmost, only hot water is in and out, and the water outlet temperature is the highest at this time. When the handle 210 is in the above two positions, the ribs 161 on the two ends of the arc plate 162 abut against the elastic component 230 on the gear sleeve 220, and the height of the rib 161 here is the highest, and the damping feel is the most obvious. It is understandable that when the handle 210 is gradually turned to the middle position, the cold and hot water enter the water outlet cavity at the same time and mix, so that the temperature gradually changes to a suitable water outlet temperature. At this time, the height of the rib 161 gradually decreases, that is, the height of the rib 161 on the arc plate 162 gradually increases from the middle to the two ends of the arc plate 162. Therefore, when the user adjusts the handle 210 to the coldest or hottest water outlet temperature, the height of the rib 161 gradually increases, the elastic component 230 is squeezed more and more, and the damping feel becomes more and more obvious, thereby notifying the user of the water temperature change and avoiding scalding or frostbite due to too high or too low water temperature.

[0049] refer to Figure 6 In some embodiments of the present invention, the elastic component 230 includes an elastic pin 231 and a spring 232. A groove 221 is provided on the tooth sleeve 220. The elastic pin 231 and the spring 232 are retractably arranged in the groove 221. Specifically, one end of the spring 232 abuts against the bottom of the groove 221, and the other end abuts against the elastic pin 231, so as to provide elastic force to the elastic pin 231, so that the elastic pin 231 always abuts against the protrusion 160. When the tooth sleeve 220 rotates, the elastic pin 231 abuts against the plurality of ribs 161 in sequence, so as to continuously extend and retract. In this process, the elastic component 230 provides damping feedback to the handle 210.

[0050] refer to Figure 2 In some embodiments of the present invention, the basin faucet 1000 further includes a solenoid valve 400 and a sensing component 500. The solenoid valve 400 is disposed between the water outlet hole 330 and the water outlet channel 140 to control the opening and closing of the water outlet hole 330 and the water outlet channel 140. The sensing component 500 is disposed on the basin faucet 1000 and is communicatively connected with the solenoid valve 400 to generate a sensing signal to control the opening and closing of the solenoid valve 400.

[0051] Specifically, the sensing component 500 can be set on the outer shell of the basin faucet 1000. When the user needs to use the basin faucet 1000 and reaches the sensing position, a sensing signal is generated to output a control signal to the solenoid valve 400, controlling the solenoid valve 400 to open, thereby connecting the water outlet 330 and the water outlet channel 140, so that water can be output through the water outlet channel 140 for user use.

[0052] The sensing component 500 may be a variety of wireless sensing devices such as an infrared sensing device.
