Description

Temperature-regulating time-delay valve core and tap

Technical Field

The invention belongs to a water tap, and particularly relates to a mechanical temperature-adjusting time-delay valve core and a water tap, which enable the water outlet temperature of the water tap to be adjusted and automatically close the water tap in a time-delay manner after the water tap is opened.

Background

The mechanical time-delay valve core and the tap move the valve plug assembly to open the valve password tap to discharge water by pressing the button, and after the button is released, the button and the valve plug assembly move to reset under the elasticity of the reset spring to automatically close the valve password tap to stop water discharge, so that the operation of closing the tap is omitted, and the time-delay closing after water discharge is realized. Such faucets are commonly found in hand-washing basins installed in public washrooms, and meet the need of people for saving water in a short time (e.g., about 10 seconds). Existing public water taps are generally connected with only one water inlet pipe for controlling the water flow of a water temperature (such as normal tap water). However, in environments where the winter temperature is colder, such mechanical time delay spools and faucets have difficulty in meeting the water flow that is more pleasant to the output water temperature, especially ice-cold tap water.

Disclosure of Invention

The invention aims to solve the technical problems and the technical task of overcoming the defect that the existing mechanical delay valve core and faucet can not adjust the water outlet temperature, and provides a temperature-adjusting delay valve core and faucet, which endow the faucet with the functions of adjusting the water outlet temperature and automatically closing after water outlet delay.

In order to achieve the above purpose, the temperature-regulating time-delay valve core of the invention is characterized by comprising:

the time delay valve core comprises a button, a valve rod, a valve plug assembly, a valve cover assembly and a valve cap; the valve rod penetrates through the valve cover assembly, a button is assembled at the upper end of the valve rod, and a valve plug assembly is assembled at the lower end of the valve rod; the valve cover assembly is used for mounting the time delay valve core to the valve seat and is provided with a valve port; the valve cap is positioned below the valve cap assembly and is kept fixed and sealed with the valve cap assembly, and the valve cap is provided with a first water passing channel; a valve plug assembly is positioned in the valve cap, and is configured to open the valve port by pushing the button to move by the valve rod and delay closing the valve port under the action of the reset spring;

the temperature regulating valve core comprises a fixed part and a rotating part, wherein the fixed part is provided with a first water inlet channel and a second water inlet channel, and the rotating part is provided with a water mixing cavity and is configured to rotate relative to the fixed part to regulate the opening degree of the first water inlet channel and the second water inlet channel communicated with the water mixing cavity;

the temperature regulating valve core is positioned below the time delay valve core, the valve cap is positioned in the water mixing cavity, the button is further configured to rotate with the rotating part through the linkage piece, and the linkage piece is provided with a second water passing channel.

The temperature-regulating time-delay valve core can be used for regulating the water outlet temperature, realizing time-delay closing after water outlet, structurally integrating the time-delay valve core with the temperature-regulating valve core, and being simpler than the structure of overlapping the independent time-delay valve core with the independent temperature-regulating valve core, so that the temperature-regulating time-delay valve core can be mounted on a valve seat to form a faucet with temperature regulation and time-delay self-closing. In addition, the button is used for opening the valve port and adjusting the water temperature, and is convenient to use.

In order to facilitate manufacturing, assembly and save manufacturing cost, the fixed part comprises a base and a fixed sealing element fixed on the base, the rotating part comprises a movable sealing element and a temperature adjusting component for rotating relative to the fixed sealing element with the movable sealing element, the temperature adjusting component is arranged in the water mixing cavity, the movable sealing element is in sealing fit with the fixed sealing element through a sealing surface, and the opening degrees of the first water inlet channel and the second water inlet channel are adjusted through rotating relative to the fixed sealing element through the movable sealing element. Accordingly, the base and the temperature adjusting member may be plastic members, which are easily manufactured by a manufacturing process such as injection molding and the like and easily form a desired relatively complex structure. While the stationary seal member and the movable seal member are typically made of ceramic materials, the joint surfaces of the two members are easily sealed and wear resistant.

In order to maintain the fitting relationship between the fixed portion and the rotating portion, the fixed portion and the rotating portion are pressed together by a bolt penetrating through the centers of the fixed portion and the rotating portion, and the bolt simultaneously serves as the center of rotation of the rotating portion. Accordingly, the sealing performance of the whole temperature regulating valve core can be ensured.

Because people can have a rotating action when pressing the button, the micro-rotation of the button can be caused, the micro-rotation can be accumulated to cause the water temperature to be adjusted unintentionally, in order to avoid the water temperature to be adjusted unintentionally, the fixed part and the rotating part are separately provided with a positioning marble and a plurality of positioning pits, the positioning marble is positioned in the positioning pits to position the rotating part, and the positioning marble is transposed among different positioning pits when the rotating part rotates relative to the fixed part. Accordingly, when a person presses the button, if the palm is provided with a rotating action applied to the button, the positioning marble is positioned in the positioning pit and can resist micro-rotation of the button, so that the water temperature is prevented from being adjusted unintentionally.

In order to simplify the structure, the linkage piece is a rotating sleeve, the upper end of the rotating sleeve is synchronously in rotating fit with the button and axially movably matched with the button, and the lower end of the rotating sleeve is synchronously in rotating fit with the rotating part. Therefore, when the button is pressed, the button can axially move relative to the rotating sleeve, so that the action that the button is pressed to open the valve port and the reset after the button is released to delay closing of the valve port are realized, and meanwhile, the rotation of the button can be transmitted to the rotating part through the rotating sleeve to regulate the water temperature.

In order to keep the rotating sleeve to transmit the rotation of the button to the rotating part, the valve cover assembly comprises the rotating sleeve, namely the rotating sleeve is used as a forming part of the valve cover assembly, and the rotating part is connected to the lower end of the rotating sleeve, so that the rotating part and the rotating sleeve are connected together and are not separated.

In order to control the volume of the temperature-regulating time-delay valve core, the volume of the faucet is not larger, a first longitudinal slot and a first longitudinal pin which are distributed at intervals are arranged at the upper end of the rotating sleeve, a second longitudinal slot and a second longitudinal pin which are distributed at intervals are arranged on the button, and the first longitudinal pin is inserted into the second longitudinal slot and the second longitudinal pin is inserted into the first longitudinal slot so as to realize synchronous running fit and axial movable fit of the upper end of the rotating sleeve and the button; the lower end of the rotating sleeve and the rotating part are separately provided with a bayonet and a clamping protrusion, and the clamping protrusion is clamped into the bayonet to realize synchronous rotation fit of the lower end of the rotating sleeve and the rotating part. Therefore, the axial length (height in installation and use) and the radial size of the temperature-adjusting time-delay valve core can be effectively controlled, and the problem that the volume of the temperature-adjusting time-delay valve core is overlarge to cause the overlarge volume of the faucet is avoided.

In order to facilitate the assembly of the temperature-adjusting time-delay valve core on the valve seat to form the faucet, the time-delay valve core forms a first assembly, the temperature-adjusting valve core forms a second assembly, and the temperature-adjusting valve core is clamped at the lower end of the time-delay valve core. Accordingly, the temperature regulating valve core and the time delay valve core form a valve core assembly, and are convenient to assemble to the valve seat together.

In order to achieve the above purpose, the faucet of the present invention is characterized in that: the valve cover assembly is connected to the valve seat through threads and is used for assembling the time delay valve core and the temperature regulating valve core on the valve seat; when the button is pressed, the valve plug component opens the valve port to enable water flow from the first water inlet interface or/and the second water inlet interface to flow through the temperature regulating valve core and the time delay valve core and then flow out of the water outlet pipe, and when the button is released, the valve plug component delays closing of the valve port to close the water tap.

Accordingly, water flows with different water temperatures are input to the faucet through the first water inlet interface and the second water inlet interface, mixed water flows out of the water outlet pipe after flowing through the temperature regulating valve core and the time delay valve core, the water flows are controlled to be opened and closed by pressing the button, the water temperature of the mixed water flows is regulated by rotating the button, water is conveniently used and the water temperature is regulated, and the water faucet is compact in structure and small in size.

In order to facilitate assembly, the temperature regulating valve core and the time delay valve core are assembled into a whole, a positioning groove and a positioning protrusion are arranged at the bottom of the temperature regulating valve core and on the valve seat separately, and the positioning protrusion is positioned in the positioning groove to position the temperature regulating time delay valve core on the valve seat.

According to the invention, the temperature regulating valve core and the time delay valve core are integrated in series according to the flow direction of water flow, the water temperature is mixed and regulated through the temperature regulating valve core, and then the water flows through the time delay valve core to delay and close after the water flow is started, so that the time delay valve core can realize delayed closing after water outlet and can regulate the water outlet temperature, the time delay valve core and the temperature regulating valve core are integrated together structurally, but the structure is simpler than that of a simple superposition series connection of an independent time delay valve core and an independent temperature regulating valve core, and the temperature regulating time delay valve core can be installed on a valve seat to form a water tap with temperature regulating and delayed self-closing. Moreover, the button is used for opening the valve port and adjusting the water temperature, so that the water heater is convenient to use.

The present invention will be described in detail with reference to specific embodiments and drawings.

As shown in fig. 1-4, the faucet includes a valve seat 2000 and a temperature-regulating time delay valve cartridge 1000. Valve seat 2000 has a first water inlet port 2301, a second water inlet port 2302, a lumen 2100, and a water outlet pipe 2200. The lower end of the lumen 2100 is plugged by a bottom plug 2300, which is typically secured to the lower end of the lumen by welding. The lower end of lumen 2100 also has a flange 2101 secured thereto. A first water inlet connection 2301 for connecting to the first water inlet pipe 3001 and a second water inlet connection 2302 for connecting to the second water inlet pipe 3002 are provided on the base plug 2300. The base plug 2300 is attached to a downwardly extending screw 2400, the screw 2400 is threaded through a press 2500, and the flange 2101 is pressed against the press 2500 on either side of the mounting location (e.g., a sink) by tightening a nut 2600 attached to the screw. The outlet pipe 2200 is connected to the side wall of the cavity tube 2100 and is communicated with the inner cavity of the cavity tube through a through hole 2105 arranged on the side wall of the cavity tube.

The temperature-regulating time delay valve core 1000 is used for being mounted on a valve seat 2000 to form a faucet. Generally, the main body of the temperature-regulating time-delay valve core 1000 is disposed in the cavity tube 2100, and the whole temperature-regulating time-delay valve core is tightly assembled to the cavity tube 2100 by the valve cover 1142 through threads, and the button 1110 is located above the cavity tube 2100.

The faucet shown in fig. 1-4 is normally closed. When water is used, the button is pressed, the faucet is started, and mixed water can flow out by taking the broken line marked with an arrow in fig. 3 and 9 as a path. The tap water is automatically closed after flowing out depending on the temperature-regulating time delay valve core 1000.

As shown in fig. 4, 10-11, the temperature-regulating time delay spool 1000 includes a time delay spool 1100 and a temperature-regulating spool 1200.

As shown in fig. 7-9, 12-13, the time delay valve spool 1100 includes a bonnet assembly 1140, a bonnet 1150, a valve plug assembly 1130, a valve stem 1120, a button 1110, and a return spring 1160.

The valve cover assembly 1140 is used to mount the temperature-regulating time delay valve core 1000 to the valve seat 2000 and to provide a water flow path. The valve cover assembly 1140 has a valve port 1141. Specifically, the valve cap assembly 1140 includes a valve cap 1142, a swivel 1170, a second seal seat 1143, and a water outlet bracket 1144. The valve cap 1142 is disposed over the sleeve 1170 and over the first axial step 1175 of the sleeve, with the wear sleeve 1145 disposed between the first axial step 1175 and the valve cap 1142, and the valve cap 1142 axially (vertically) positions the sleeve 1170 when threadably connected to the lumen 2100 such that the sleeve is rotatable and cannot move up and down. The second seal housing 1143 is sleeve-shaped and is threadably attached to the inner wall of the rotor sleeve 1170. The sleeve 1170 seals against the second seal housing 1143. The second seal seat 1143 presses down the outlet bracket 1144, the outlet bracket 1144 presses against the flange 1153 of the bonnet, whereby the outlet bracket 1144 and the bonnet 1150 are axially pressed against the second axial step 1176 of the inner wall of the rotor sleeve by the second seal seat 1143, ensuring structural integrity.

The valve port 1141 is a lower port of the bore of the outlet bracket 1144. The abutment of the second axial step 1176 of the sleeve 1170, the outlet bracket 1144 and the flange 1153 of the bonnet seals against the flow of water from below directly to the outside of the outlet bracket, forcing the flow of water from below through the valve port to the inside of the valve cover assembly and radially to the outside of the valve cover assembly. Specifically, the rotary sleeve 1170 is provided with a radial second water passing channel 1171, and the water outlet bracket 1144 is provided with a radial third water passing channel 1146. When water is discharged, water flow from the valve port flows from the inner side of the valve cover assembly to the outer side of the valve cover assembly through the third water passing channel 1146 and the second water passing channel 1171, and finally flows to the water outlet pipe through the through hole on the cavity pipe. The second water passage 1171 and the third water passage 1146 may be grooves or through holes.

As shown in fig. 14-15, the valve cap 1150 is cylindrical and is open at its upper end and outwardly provided with a flange 1153, the lower end of which is closed. A plurality of through holes are formed in the side wall of the valve cap adjacent to the opening as a first water channel 1151.

As shown in fig. 7-9, a valve plug assembly 1130 is positioned within the bonnet 1150 and is capable of moving up and down. The bonnet 1150 is sealed to the valve plug assembly 1130 by a seal. Specifically, a seal ring 113b having a Y-shaped cross section is fitted to the lower end of a first seal seat 113a described below so that a valve plug assembly fitted to the lower end of a valve stem, such as a piston, is seated in a bonnet.

The valve plug assembly 1130 is configured to open the valve port 1141 by depressing a button to move downward and to return upward under the force of the return spring 1160 to close the valve port 1141.

In the configuration shown in FIGS. 7-9 and 14-15, the valve plug assembly 1130 includes a first seal seat 113a, a liner 113c, and a flexible seal 113d. As shown in fig. 17 to 18, the first sealing seat 113a is provided with a ring groove 113e and a radial flow hole 113f, the radial flow hole 113f is positioned in the ring groove 113e, a boss 113g is arranged in the ring groove 113e, an outer port of the radial flow hole is positioned on the boss 113g, and a flow groove 113h is arranged on the end face of the boss 113 g. The radial flow holes 113f are provided on both sides with protruding portions 113i, which are in the form of ribs. An annular flexible seal 113d is fitted in the annular groove 113e, and the flexible seal 113d is supported by the projection 113i so as to maintain a clearance with the outer port of the radial flow hole 113 f. The bushing 113c is sleeved outside the flexible sealing member 113d, and the bushing 113c is provided with a mesh 113j for communicating the inside and the outside of the bushing.

As shown in fig. 7-9 and 14-15, the valve plug assembly 1130 is mounted on the valve stem 1120 by the first sealing seat 113a and retains the two in axial relative movement, i.e., the valve stem 1120 is threaded through the valve plug assembly in a vertically movable manner. A first seal 1121 and a second seal 1122 are provided between the valve stem 1120 and the first seal seat 113a, and are mounted in a ring groove of the valve stem 1120 or positioned by a shaft retainer ring that is engaged with the valve stem. The first seal and the second seal fitted around the valve stem are held in contact with the first seal seat 113a by the elastic force of the compression spring 1123, so that a communication chamber 113k is formed inside the first seal seat 113a, around the valve stem 1120, and between the first seal 1121 and the second seal 1122. The diameter of the first sealing element is smaller than that of the second sealing element, so that the first sealing element and the second sealing element can be sleeved on the valve rod together to be assembled with the first sealing seat.

Based on the structure of the valve plug assembly described above, the valve plug assembly 1130 is positioned within and seals with the valve cap 1150 to form a seal cavity 1152 within the valve cap. The size of the seal chamber 1152 is changed by the stem 1120 being carried up and down in the bonnet 1150 by the valve plug assembly 1130. The valve plug assembly and valve stem have a fill channel 113m, and depressing the button causes the valve plug assembly to move downward to reduce the volume of the seal chamber 1152 to cause the seal chamber to drain outwardly through the fill channel, and to fill the seal chamber through the fill channel by expanding the volume of the seal chamber when the valve plug assembly is moved upward for return under the force of the return spring. This water filling channel 113m is indicated in fig. 8 by a dashed line of an unbended arrow.

The valve rod 1120 is vertically movably installed through the valve cover assembly 1140 and sealed at the installed location. Specifically, the valve rod passes through the second sealing seat 1143 in a vertically moving manner, the second sealing seat 1143 and the valve rod 1120 are sealed by a sealing element 1147 embedded in the center of the second sealing seat, and the cross section of the sealing element 1147 is Y-shaped to bear enough water pressure. The upper end of the valve stem 1120 is provided with a button 1110 and a return spring 1160 is supported between the button 1110 and the second seal housing 1143 for urging the button to return with the valve stem and valve plug assembly upon depression of the button. A communication hole 1124 is provided in the valve rod 1120, and communicates the communication chamber 113k with the seal chamber 1152. An axial through hole is arranged in the valve rod, an adjusting rod 1125 is assembled in the axial through hole through threads, and a screwing structure 1126 is arranged at the upper end of the adjusting rod 1125 so as to enable a screwdriver to screw the adjusting rod to move up and down to adjust the size of the communication hole 113k. In particular, the button 1110 is provided with a through hole 1113 corresponding to the screwing structure, and the aperture of the through hole 1113 is smaller than the outline of the head 1127 of the adjusting rod, so as to avoid the adjusting rod from being taken out of the valve rod through the through hole. A cap 1114 is disposed within the through hole 1113 to conceal the threaded structure. Removal of the cap 1114 exposes the screw on mechanism 1126, which can be moved up and down with a screwdriver to adjust the size of the communication orifice and the reset time of the valve plug assembly, i.e., to adjust the time for delayed closure after the water flow is turned on. A sealing piece is arranged between the adjusting rod and the wall of the axial through hole and used for preventing water in the communication hole from flowing to the axial through hole, so that water leakage is avoided. For easy assembly, the valve stem is formed by connecting two sections of rods. Further, the upper end of the valve stem is assembled with the button by nut 1115.

The water filling passage 113m shown by a broken line of an unbended arrow in fig. 8 includes a communication hole 1124, a communication chamber 113k, a radial flow hole 113f, and a mesh 113j on the liner, which are sequentially communicated. The water filling channel 113m is used to provide water from outside the bonnet to fill the seal chamber 1152 through the first water channel 1151 when the valve plug assembly is moved upward for reset.

As shown in fig. 12 to 13, the temperature-regulating valve core 1200 includes a fixed portion 1210 provided with a first water inlet passage 1211 and a second water inlet passage 1212, and a rotating portion 1220 having a water mixing chamber 1221 and configured to rotate relative to the fixed portion to regulate the opening degrees of the first water inlet passage and the second water inlet passage communicating with the water mixing chamber.

Specifically, the fixed portion 1210 includes a base 1213 and a fixed seal 1214 fixed to the base, the rotary portion 1220 includes a movable seal 1222 and a temperature adjusting member 1223 for rotating with the movable seal relative to the fixed seal, the water mixing 1221 chamber is provided in the temperature adjusting member 1223, the movable seal 1222 is sealingly engaged with the fixed seal 1214 through a sealing surface and rotates with the movable seal relative to the fixed seal to adjust the opening of the first water intake passage and the second water intake passage. Two corresponding groups of through holes are arranged on the base and the fixed sealing piece, one group of through holes forms a first water inlet channel 1211, and the other group of through holes forms a second water inlet channel 1212. The movable seal 1222 has a gap 1226. The lower end of the temperature adjusting component is provided with a channel 1228 corresponding to the notch, and the channel 1228 is used for communicating the water mixing cavity with the first water inlet channel and the second water inlet channel. When the movable sealing member rotates relative to the fixed sealing member, the sealing surface and the passage 1228 change positions relative to the first water inlet passage and the second water inlet passage to adjust the opening degree of the first water inlet passage and the second water inlet passage communicated with the water mixing cavity.

Further, the fixed portion and the rotating portion are pressed together by a bolt 1230 penetrating the centers of the both. The fixed part and the rotating part are separately provided with a positioning ball 1224 and a plurality of positioning pits 1215, the positioning ball 1224 is positioned in the positioning pit 1215 to position the rotating part, and the positioning ball is shifted between different positioning pits when the rotating part rotates relative to the fixed part.

To avoid excessive loss of position of the rotating part relative to the fixed part, the base 1213 is provided with two spaced stops 1217, and the temperature regulating member is provided with a protrusion 1227 extending between the two stops for limiting the rotation amplitude of the rotating part relative to the fixed part.

The temperature control valve cartridge 1200 is positioned below the time delay valve cartridge 1100 and the valve cap 1150 is positioned within the water mixing chamber 1221. The button 1110 is also configured to rotate with the rotating portion 1220 via a linkage having a second water passage 1171. When the water is discharged through the faucet, water flows through the temperature regulating valve core and then flows through the time delay valve core. The linkage is served by the swivel 1170 described previously that forms the valve cover assembly.

The upper end of the rotating sleeve 1170 is synchronously and rotatably engaged with the button 1110 and axially movably engaged, and the lower end of the rotating sleeve 1170 is synchronously and rotatably engaged with the rotating portion 1220. The rotating portion 1220 is connected to the lower end of the rotating sleeve 1170. Specifically, the upper end of the sleeve 1170 is provided with first longitudinal slots 1172 and first longitudinal pins 1173 that are spaced apart. The button 1110 is provided with a second longitudinal slot 1111 and a second longitudinal pin 1112 which are spaced apart. The first longitudinal pins are inserted into the second longitudinal slots, and the second longitudinal pins are inserted into the first longitudinal slots, so that the upper end of the rotating sleeve is synchronously and rotatably matched with the button and axially and movably matched with the button. In the illustration, the button is an assembly, and in other embodiments, the button may be a member. The lower end of the rotating sleeve 1170 is provided with a bayonet 1174 and a clamping convex 1225 separately from the rotating part 1220, and the clamping convex 1225 is clamped into the bayonet 1174 to realize synchronous rotation fit between the lower end of the rotating sleeve and the rotating part. In the assembled state, the hub 1170 is maintained in a relatively fixed relationship with the temperature regulating member 1223 and a seal is provided therebetween such that the two are identical to one another, preventing the mixed water in the water mixing chamber from overflowing outwardly.

The time delay valve core 1100 forms a first assembly, the temperature regulating valve core 1200 forms a second assembly, and the temperature regulating valve core 1200 is clamped at the lower end of the time delay valve core 1100. Specifically, the inner flange 1177 at the lower end of the rotating sleeve hooks the outer flange 1229 at the upper end of the temperature adjusting member to realize clamping.

As shown in fig. 7-9, the temperature-regulating time delay valve core 1000 has a first sealing portion 2102 between the outer wall 1170 of the sleeve and the inner wall of the lumen 2100, and a second sealing portion 2103 between the outer wall of the temperature-regulating member 1223 and the inner wall of the lumen 2100.

To assemble the temperature-delay valve cartridge 1000 of fig. 7-8 to the valve seat 2000 as shown in fig. 3, the temperature-delay valve cartridge 1000 is positioned within the cavity 2100 as shown in fig. 4 and the valve cap 1142 is threaded onto the cavity 2100, the temperature-delay valve cartridge being assembled and secured to the valve seat. The first sealing part 2102 and the second sealing part 2103 are sealed by sealing rings, a water outlet cavity 2104 is formed between the first sealing part and the second sealing part, the water outlet cavity 2104 is communicated with the water outlet pipe 2200 through a through hole 2105 on a cavity pipe, and the water outlet cavity 2104 is also communicated with the valve port 1141 through a second water passing channel 1171 on the rotary sleeve 1170 and a third water passing channel 1146 on the water outlet bracket 1144. The first water inlet 2301 interfaces with the first water inlet 1211 and the second water inlet 2302 interfaces with the second water inlet 1212.

4-5, the temperature-adjusting valve core and the time-delay valve core are assembled into a whole, a positioning groove 2303 and a positioning protrusion 1216 are separately arranged on the bottom of the temperature-adjusting valve core 1200 and the bottom plug 2300 of the valve seat 2000, and the positioning protrusion is positioned in the positioning groove to position the temperature-adjusting time-delay valve core on the valve seat, so that the temperature-adjusting valve is convenient to assemble.

After the faucet is installed, the first water inlet connector 2301 is connected with the first water inlet pipe 3001, the second water inlet connector 2302 is connected with the second water inlet pipe 3002, and the first water inlet pipe 3001 and the second water inlet pipe 3002 are respectively connected to water sources with different water temperatures, so that the water temperatures can be adjusted through rotating buttons.

As shown in fig. 1-3 and 7-8, normally, the valve plug assembly 1130 closes the valve port 1141 under the force of the return spring 1160 and the faucet does not discharge water. The water in the water mixing chamber 1221 fills the seal chamber 1152 through the first water passage 1151 and the water filling passage 113m of the valve cap 1150, and the volume of the seal chamber 1152 is maximized.

When water is used, as shown in fig. 9, the button 1110 is pressed to overcome the elastic force of the return spring 1160, so that the button 1110 and the valve rod 1120 move downwards together, and because the sectional area of the valve rod is smaller than that of the valve plug assembly, the valve rod moves in the valve cap before the valve plug assembly by overcoming the elastic force of the compression spring, so that the sealing cavity 1152 is reduced, the sealing part of the first sealing piece 1121 and the second sealing piece 1122 is separated from the sealing part to leave the overflow channel 113n, the water in the sealing cavity 1152 overflows upwards from the overflow channel 113n, the resistance of the valve plug assembly to the subsequent movement in the valve cap is reduced, and the pressing of the button is easy and labor-saving. As the water in the seal chamber 1152 overflows upwardly from the overflow channel 113n, the valve plug assembly moves downwardly under the influence of the compression spring, and the valve plug assembly 1130 moves downwardly within the valve cap 1150 to reduce the volume of the seal chamber 1152, forcing the seal chamber to drain outwardly through the fill and overflow channels, i.e., under the squeezing of the valve plug assembly, the water in the seal chamber is forced out through the fill and overflow channels until the valve plug assembly moves downwardly into position to form a communicating chamber. Simultaneously, the valve plug assembly 1130 after being moved downward opens the valve port 1141, and water flows from the first water inlet tube 3001 and/or the second water inlet tube 3002 sequentially through the water mixing chamber 1221, the first water passage 1151 of the valve cap, the valve port 1141 on the water outlet bracket, the third water passage 1146 on the water outlet bracket, the second water passage 1171 on the swivel 1170, the water outlet chamber 2104, and the water outlet tube 2200 along the paths shown by the dashed lines labeled arrows in fig. 3 and 9.

After releasing the button from the state shown in fig. 9, the button 1110, the valve stem 1120 and the valve plug assembly 1130 are restored under the elastic force of the restoring spring 1160, and due to the existence of the sealing chamber 1152, there is a certain suction force for the upward restoration of the valve plug assembly 1130, and the valve plug assembly cannot be quickly restored, but is slowly restored as water flows through the water filling channel 113m to fill the sealing chamber 1152. Therefore, the time for water to flow through the water filling channel to fill the sealing cavity is the time delay of the time delay valve core. After the valve plug assembly 1130 is reset to the position shown in FIGS. 7-8, the valve port 1141 is closed and the faucet is no longer discharging water.

When the water temperature is to be adjusted, only the button 1110 is required to be rotated, the button 1110 is rotated by the temperature adjusting member 1223 through the rotating sleeve 1170, and the rotating portion 1220 is rotated relative to the fixed portion 1210 to adjust the opening of the first water inlet channel 1211 and the second water inlet channel 1212 communicated with the water mixing chamber 1221 through the channel 1228, and the opening of the first water inlet channel 1211 and the second water inlet channel 1212 is increased one by one and is decreased the other synchronously. The flow rate of hot water entering the water mixing cavity is increased, the flow rate of cold water entering the water mixing cavity is reduced, and the water temperature is increased. The flow of cold water entering the water mixing cavity is increased, the flow of hot water entering the water mixing cavity is reduced, and the water temperature is reduced. Wherein the push button 1110 is shown in fig. 16 in a rotational engagement with the temperature regulating member 1223 via the swivel 1170.

The faucet can be installed on different occasions or debugged after installation, or the cover on the button can be opened to change the delay time in the use process, and the screwing structure of the adjusting rod can be screwed by using tools such as a screwdriver to realize adjustment. Because the aperture of the through hole of the button is smaller than the outline of the head 1127 of the adjusting rod, the adjusting rod can not be taken out through the through hole on the button, and the time delay adjustment is prevented from being damaged by taking out the adjusting rod.

Because the water filling channel exists, especially the cooperation structure of the flexible sealing element and the outer port of the radial flow hole and the cooperation of the communication hole and the adjusting rod form the superposition of two sections of delay channels, the radial flow hole and the communication hole have larger apertures to prevent the blockage caused by microorganism breeding and ensure delay, so that the water filling channel is not easy to block, the delay valve core always keeps the delay function, the delay time is kept stable, the service life of the faucet is prolonged, and the waste of water resources is avoided. Compared with the superposition of the two sections of delay channels in the scheme, if only the matching structure of the flexible sealing element and the outer port of the radial flow hole is arranged or only the communication hole is configured, when the same delay time is reached, the aperture of the radial flow hole or the aperture of the communication hole needs to be reduced, and the blockage is easy to be caused by microorganism breeding. In summary, the delay valve core can always maintain a stable working state by self-cleaning the flow channel and two-section delay superposition means, so that the service life of the faucet is prolonged.
