As shown in fig. 1 to 8, the present invention provides a time-delay tap 1, which exemplarily shows a time-delay tap 1 according to the present invention, and includes a housing 10, a body pin 11 accommodated in the housing 10 (detachably connected to the housing 10), a time-delay valve element 12 installed in the body pin 11, a pipe body 13 installed in the body pin 11, and a handle 14 capable of pivotally pressing the time-delay valve element 12.

As shown in fig. 3, the housing 10 includes a base 100 and a water nozzle 101, and the base 100 and the water nozzle 101 may be made as an integrally formed member and have the same inner cavity. The base 100 is inclined in the longitudinal direction, but this is only an example and is not intended to limit the shape of the base 100. The water nozzle 101 is located on the circumferential surface of the base 100 and is arranged obliquely with respect to the radial direction of the base 100. Such a housing 10 is suitable for a tilting delay tap 1, although a person skilled in the art may adapt the housing 10 according to the shape requirements of the delay tap 1.

Fig. 1 and 2 show an exemplary body pin 11 according to the present invention, which mainly includes a main body portion 111 and a base portion 110. After the body pins 11 are mounted through the table, the base 110 is located below the table and the body 111 is located above the table. The base 110 is mainly used for engaging a mounting nut that fixes the body pin 11. The surface of the base 110 is provided with threads and the mounting nut is adjustable to engage the length of the base 110 according to the thickness of the table top. In the embodiment shown in fig. 5, the main body portion 111 of the body pin 11 includes a first engaging portion 114 and a second engaging portion 115, and both the first engaging portion 114 and the second engaging portion 115 are configured in a tubular shape with the first engaging portion 114 and the second engaging portion 115 arranged at an angle therebetween. The first engagement portion 114 is configured to receive the delay spool 12, the delay spool 12 is threaded at an outer periphery thereof, the first engagement portion 114 is provided with an internal thread, and the delay spool 12 is (detachably) mounted in the first engagement portion 114 by a threaded connection. The second joint portion 115 is connected to the pipe body 13. The pipe body 13 is provided at both ends with fittings 130, one of the fittings 130 being positioned in the second engaging portion 115 by a female connection. The surface of the connector 130 is provided with a plurality of grooves, sealing rings are accommodated in the grooves, and the socket connection is convenient to install and has a good sealing effect, so that the fluid in the pipe body 13 is prevented from overflowing.

Furthermore, referring to fig. 4 to 7, the housing 10 is provided with a first stop 103 at the transition between the water nozzle 101 and the base 100 (e.g. at the position where the water nozzle 101 extends from the base 100), and a second stop 104 at the outlet end of the water nozzle 101. The first stop 103 is typically configured as a semi-annular protrusion that extends towards the inside of the tap 101 to taper the internal cavity of the tap 101. The aforementioned joint 130 of the tube 13 prevents the tube 13 from moving towards the outlet end of the housing 10 by the fluid power after the fluid is conducted by abutting against the protruding member, thereby preventing the tube 13 from being disconnected from the second engaging portion 115.

The aforementioned body pin 11 is further provided with a flange 112 at the junction of the main body portion 111 and the base portion 110, the flange 112 is configured as a sheet-like member extending in the radial direction of the base portion 110, and a positioning hole 113 is arranged on the flange 112. The housing 10 is provided at the bottom end of its base 100 (i.e., the side of the base 100 remote from the delay spool 12) with a lug 105 extending in the radial direction of the base 100, and the lug 105 is provided with an engagement hole 106. After the body pin 11 and the tube 13 are assembled by the socket connection, the positioning hole 113 on the flange 112 of the body pin 11 is aligned with the engaging hole 106 (provided with threads inside) on the lug 105, and the body pin 11 and the housing 10 are fixed to each other by a connecting member (such as a screw, a bolt, etc.).

Referring to fig. 5 to 6, after the time delay spool 12 is coupled to the first coupling portion 114 of the body pin 11, the positioning socket 15 is inserted into the base 100 of the housing 10, since the side surface of the positioning socket 15 is provided with a threaded hole and the side surface of the base 100 of the housing 10 is provided with a receiving hole, after the threaded hole is aligned with the receiving hole, the positioning socket 15 can be fixed in the base 100 of the housing 10 by using another connector (such as a screw or a bolt, and other available connectors will occur to those skilled in the art) to couple the threaded hole of the positioning socket 15 through the receiving hole. The positioning seat 15 is provided with a through hole 150 opened along the axial direction thereof, and after the positioning seat 15 is positioned in the base 100, the valve rod of the delay valve core 12 passes through the through hole 150 of the positioning seat 15. The inner wall of the base 100 is provided with a concave pit 102 (on the inner wall of the side of the base 100 receiving the positioning seat 15), and the radial direction of the positioning seat 15 is provided with a convex block 154, wherein the convex block 154 can be a square block, a round block with a regular shape or an irregular and asymmetric convex block 154. When the spud 15 is mounted in the base 100, the protrusions 154 of the spud 15 are fitted into the recesses 102 of the base 100, and such fitting can restrict the rotation of the spud 15 and the housing 10.

In addition, the inner wall of the base 100 is further provided with a protrusion 107 in a ring shape, the protrusion 107 extends radially from the inner wall of the base 100 toward the inside and abuts against the main body 111 (specifically, the first engaging portion 114) of the body pin 11 after the body pin 11 is installed in the housing 10, so that the first engaging portion 114 is coaxial with the positioning seat 15 installed in the housing 10, and thus the delay valve element 12 installed to the first engaging portion 114 is coaxial with the positioning seat 15 and the housing 10, and such a structural design avoids the influence on the operation comfort caused by the blocking force when the delay valve element 12 is pressed.

Referring to fig. 1 and 8, the handle 14 is pivotally connected to the positioning socket 15. The positioning socket 15 is provided with a pivot mounting opening 152 on an upper surface thereof (i.e., a surface facing the side of the handle 14), the pivot mounting opening 152 being annular and standing on the upper surface. The pivot mounting holes 152 are preferably provided in two, or one or more than two, and can be selected as required by those skilled in the art. The handle 14 is provided with a pair of through holes in a radial direction thereof, and after the through holes of the handle 14 are aligned with the pivot mounting holes 152 of the positioning socket 15, the handle 14 is pivotally connected to the positioning socket 15 through the through holes and the pivot mounting holes 152 by means of a pivot connection member (such as a pin in this embodiment). As shown in fig. 6, an inner side (a side facing the base 100) of the handle 14 is provided with an abutting portion 140, and the abutting portion 140 is a structure extending from a top surface of the handle 14 toward the inner cavity of the housing 10, and is configured to abut against a stem (or a bonnet fitted over the stem) of the time delay valve element 12 and press the stem to activate the time delay valve element 12 when the handle 14 is pressed and pivoted relative to the positioning seat 15. The abutting portion 140 may be a rib in this embodiment. The width of the rib is slightly larger than the diameter of the opening at the top end of the valve cover, and the rib is aligned with the opening of the valve cover, so that the handle 14 can act on the time delay valve core 12 in a force uniformly distributed mode.

Referring to fig. 3 to 8, after the pipe body 13 is installed in the housing 10, the other joint 130 of the pipe body 13 abuts against the second stop 104 of the inner wall of the housing 10 by means of the radial flange 112, and the pipe body 13 can be stably arranged in the water nozzle 101 by such cooperation. Thereafter, the flange 112 is pressed against the second abutment 140, such as by a threaded connection, by further engagement of the retaining nut to the outlet end of the water nozzle 101. In order to optimize the water outlet and to save water, a bubbler is also mounted at the outlet end of the tap 101, partly housed in a retaining nut and positioned in the tap 101 by means of the bubbler housing 10 engaging the tap 101.

In order to prevent the delay tap 1 from rusting the body pin 11 under a table when the delay tap is used by water remained or splashed on the table surface, a spacer 17 shown in fig. 6 is adhered to the bottom surface of the flange 112 of the body pin 11 to separate the body pin 11 from the bottom of the shell 10. Thus, even if water on the table enters the bottom of the housing 10, the spacer 17 can separate the water from the body pin 11 to avoid possible corrosion of the body pin 11. The spacer 17 may be a foam pad provided with an escape hole through which the rotation preventing member 16 for restricting the rotation of the body pin 11 and the housing 10 is coupled to the housing 10.

After time delay tap 1 is installed on the mesa, owing to adopt the mode of pressing to start time delay tap 1, reciprocal a lot of pressing down probably leads to body pin 11 and casing 10 to take place to rotate, and such rotation obviously influences user's use and experiences, consequently the utility model discloses an embodiment, as shown in fig. 5, be provided with spacing hole 116 on the flange 112 of body pin 11, this spacing hole 116 tight fit prevents revolving parts 16 (can select to prevent revolving the pin). When the anti-rotation limiting hole 116 is formed in the table top during installation, the anti-rotation piece 16 is partially inserted into the anti-rotation limiting hole 116, and the body pin 11 and the shell 10 are prevented from rotating possibly caused by multiple times of pressing through the matching of the anti-rotation piece and the anti-rotation limiting hole 116.

Further, a mounting pad is bonded to the body pin 11. After the body pins 11 are mounted on the table, the body pins 11 may be locked on the table using mounting nuts in order to fix the body pins 11. Because the mounting nut has a relatively small contact area with the table top, a mounting washer is also employed between the table top and the mounting nut in order to further stabilize the mounting pin. Because the size of mesa differs, if install time delay tap 1 to the less mesa of thickness on, the installation gasket that the anti-rotation piece 16 that shows in fig. 6 to 8 probably contacts and is located the mesa below and install on the basal portion 110 of body pin 11, consequently, is equipped with the trompil on the installation gasket and dodges anti-rotation piece 16, so that the utility model discloses a time delay tap 1 can be applicable to the mesa of various thicknesses. The mounting pad can be abutted against the lower part of the table top, and the mounting pad can be mainly used for stabilizing the body pin 11 relative to the table top due to the large contact area between the mounting pad and the table top. The base 110 of the body pin 11 also engages a mounting nut that compresses the mounting washer under the table.

In the specific installation, referring to fig. 6 to 8, the installation gasket is adhered (glued) to the bottom surface of the flange 112 of the body pin 11, and the anti-rotation pin is inserted into the limiting hole 116 on the flange 112 by interference fit. The pipe body 13 is placed into the water nozzle 101 of the housing 10, the two joints 130 of the pipe body 13 are respectively abutted against the first stopping portion 103 and the second stopping portion 104, and the fixing nut, the bubbler and the bubbler housing 10 are sequentially placed into the water nozzle 101. The faucet pin is placed in the housing 10, the second engagement portion 115 is in socket-fit connection with one of the tabs 130 of the pipe body 13, and the time delay valve element 12 is installed in the first engagement portion 114 of the body pin 11. Subsequently, the positioning seat 15 and the handle 14 may be sequentially installed, or the handle 14 and the positioning seat 15 may be assembled and then assembled with the housing 10. Taking the latter as an example, the handle 14 and the positioning socket 15 are pivotally connected together by a pin passing through the pivot mounting hole 152 on the top surface of the positioning socket 15 and a through hole on the handle 14. When the positioning socket 15 connected with the handle 14 is installed in the housing 10, the concave recesses 102 on the housing 10 cooperate with the convex blocks 154 of the positioning socket 15 to limit the rotation of the positioning socket 15 relative to the housing 10. In addition, the positioning socket 15 is fixed with respect to the housing 10 by engaging with screws to the screw holes of the positioning socket 15 through the housing holes of the housing 10.

According to the utility model discloses a time delay tap 1's working method's embodiment as follows:

when the time delay faucet 1 is used, first, the tip of the handle 14 is pressed, and the contact portion 140 presses the time delay valve body 12. The delay valve element 12 is started, the valve rod of the delay valve element 12 is provided with a hollow cavity, a needle-shaped rod is accommodated in the hollow cavity in a detachable mode, the valve rod is provided with two small holes which are distributed along the axial direction and communicated with the hollow cavity, a leather cup is sleeved on the valve rod, the leather cup divides the independent cavity of the valve element into two parts (such as an upper cavity and a lower cavity), compressible gas or liquid is accommodated in the independent cavity, taking liquid as an example, the two small holes in the valve rod are respectively positioned at the upper part and the lower part of the leather cup, when the valve rod is pressed, the valve rod drives the leather cup to move downwards, the liquid in the lower cavity is forced into the upper cavity, the valve rod opens the water outlet of the valve element at the moment, a flow path from the body pin 11 to the pipe body 13 of the delay tap 1 is conducted, the fluid is guided into the pipe body 13, thereby fully mixing the fluid and the air, improving the scouring force of the fluid and achieving the purpose of saving water. After the flow path is conducted, under the action of the restoring force of the spring, the leather cup pushes liquid in the upper cavity to gradually enter the cavity of the valve rod through the upper hole of the valve rod and then return to the lower cavity through the small hole in the lower part of the valve rod until the leather cup returns to the initial position again to achieve balance of the upper cavity and the lower cavity, in the process, the valve rod slowly moves upwards under the action of hydraulic pressure in the lower cavity until the time delay valve core 12 of the water outlet is closed, the flow path is blocked again, and the time delay faucet 1 is closed. In addition, the time delay valve core 12 can also change the time delay by adjusting the depth of the needle rod in the hollow cavity, and generally, the larger the depth distance of the needle rod in the hollow cavity is, the shorter the time delay is, that is, the larger the depth distance of the needle rod in the hollow cavity is, the more space of the hollow cavity is occupied, the volume of the liquid flowing into the hollow cavity from the independent cavity is reduced, and the time delay is shortened. Of course, those skilled in the art will appreciate that other delay valve spools capable of achieving the function of adjusting the delay time may be used in the present invention, and this is not limited by the above description.
