[0002] The valve core is an essential part of the faucet in bathroom equipment. The valve core uses its movement to achieve the basic functions of direction control, pressure control or flow control. In particular, the valve core in the faucet is mainly used to control the opening and closing of the water flow. The valve core is mainly composed of multiple parts such as the valve stem, valve plate, sealing gasket, and valve seat. During production, multiple parts need to be produced separately, and then assembled after production to obtain a valve core body.

[0003] The traditional valve core needs to be produced from multiple parts during production, and after production, the multiple parts need to be assembled to form the valve core body, which cannot reduce the production cost of the valve core, and the structure of the valve core is complicated. Utility Model Content

[0004] The purpose of the utility model is to address the defects and shortcomings of the prior art and to provide a new type of valve core body that does not require the production of multiple parts and can be made into a valve core body without assembling multiple parts, thereby reducing the production cost of the valve core and having a simple valve core structure.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of valve core body, including a tube body, a water inlet opening opened at one end of the tube body for allowing external water to flow into the tube body, a water outlet opened at the other end of the tube body and connected to the water inlet opening for allowing the water flowing into the tube body to be discharged outward, a connecting device arranged at one end of the tube body for fixed connection with an external water inlet pipe, and an installation device arranged at the other end of the tube body for connecting with an external water outlet part, and the water outlet is eccentrically arranged on the other end face of the tube body.

[0006] A further improvement is that the connecting device includes a threaded surface arranged at one end of the tube body, and the threaded surface is arranged on the outer peripheral side of the tube body.

[0007] A further improvement is that: the connecting device comprises a connecting positioning groove opened at one end of the tube body, and the connecting positioning groove is opened at the outer peripheral side of the tube body.

[0008] A further improvement is that the installation device includes a connecting opening opened on the other end of the tube body and connected to the water inlet opening, and a connecting bolt arranged in the connecting opening.

[0009] A further improvement is that an elastic sealing sheet is provided at one end of the tube body.

[0010] A further improvement is that: one end of the pipe body is provided with a positioning device for cooperating with an external water outlet.

[0011] A further improvement is that the positioning device includes a mounting slot opened at one end of the tube body, a positioning block that can be raised and lowered on the tube body and located in the mounting slot, and a compression spring that is arranged between the positioning block and the tube body and located in the mounting slot.

[0012] A further improvement is that a rotating sleeve is provided on the other end of the tube body in the connecting opening, the rotating sleeve is clearance-matched with the connecting opening, the screw portion of the connecting bolt passes through the rotating sleeve, and the screw portion of the connecting bolt is slidingly matched with the rotating sleeve.

[0013] A further improvement is that a water stop core is arranged at one end of the tube body in the water inlet opening.

[0014] Further improvement is: the water stop core includes a mounting sleeve arranged at one end of the tube body and located in the water inlet opening, a mounting opening opened at the left end of the mounting sleeve, a water stop hole opened at the right end of the mounting sleeve and connected to the mounting opening, a connecting sleeve arranged at the left end of the mounting sleeve and located in the mounting opening, at least two support rods arranged between the connecting sleeve and the mounting sleeve, a sliding rod with one end slidably arranged on the connecting sleeve and the other end close to the water stop hole, a water stop plate arranged at the other end of the sliding rod, a reset spring arranged between the water stop plate and the connecting sleeve and sleeved on the outside of the sliding rod, a flow area for water to flow through is formed between the support rod and the mounting sleeve, the diameter of the water stop hole is smaller than the diameter of the mounting opening, and the diameter of the water stop plate is larger than the diameter of the water stop hole.

[0015] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: compared with the traditional valve core, the tube body is integrally formed, and when controlling, it is only necessary to rotate the external water outlet part or valve seat so that the water outlet corresponds to the water outlet hole position on the water outlet part or valve seat, so as to realize the control of water flow, without the need to produce multiple parts, and there is no need to assemble multiple parts to form the valve core body, which can reduce the production cost of the valve core and the structure of the valve core is simple.

[0016] Further effect: when the other end of the tube body is mounted on the valve seat, the elastic sealing sheet can improve the sealing between the other end of the tube body and the valve seat, and further prevent water leakage when the shell body rotates.

[0017] Further effect: when the first connecting hole and the second connecting hole are set, when the shell is rotated, the positioning block slides downward in the installation groove and squeezes the compression spring. When the water outlet corresponds to the position of the first connecting hole or the second connecting hole, the compression spring releases elastic potential energy to push the positioning block to engage with one of the positioning holes. At this time, a "click" sound is formed and rotation resistance is formed, thereby achieving the positioning effect.

[0018] Further effect: when the water outlet corresponds to the first connecting hole or the second connecting hole on the valve seat, a space is formed for water to be discharged outward. At this time, the water stop plate is pushed by the water flow at the water inlet end to drive the sliding rod to slide to the left on the connecting sleeve, so that the water stop plate and the water stop hole are disengaged, and the water flows into the installation opening from the water stop hole and flows into the water inlet opening on the pipe body from the flow area, so that the water flows out from the water outlet; and when the water outlet corresponds to the closed water groove on the valve seat or does not correspond to other water outlets, the water flow at the other end of the pipe body cannot be discharged outward, so that the pressure in the water inlet opening is increased, and the water flow at the water inlet end can no longer push the water stop plate to move to the left. At this time, the reset spring resets and pushes the water stop plate to slide to the right, thereby closing the water stop hole to further prevent water from continuously pouring into the water inlet opening and causing leakage.

The first connecting hole a4 can be set as a water outlet hole, and the second connecting hole a5 can be set as a closed water groove. When the water outlet 3 corresponds to the first connecting hole a4, the water in the tube body 1 is discharged from the water outlet 3 to the first connecting hole a4, thereby realizing the water outlet effect. When the water outlet 3 corresponds to the second connecting hole a5, the water discharged from the water outlet 3 enters the closed water groove, thereby realizing the water closing effect. The first connecting hole a4 and the second connecting hole a5 can also be set as water outlet holes, and two connecting holes are respectively set on the shell a1. The two connecting holes are respectively connected to the first connecting hole a4 and the second connecting hole a5, and the water outlet 3 corresponds to the position of the first connecting hole a4 or the second connecting hole a5, thereby realizing different water outlet positions.
