[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides a mixer with a split structure, comprising a fixed part and a replaceable part, wherein the fixed part and the replaceable part are connected by a pin 14, and one end of the replaceable part is provided with a socket 17 adapted to the pin 14; the replaceable part includes but is not limited to a first connecting female head 13, a second connecting female head 15 and a third connecting female head 16. With such an arrangement, when the mixer is in use, the user can adapt the mixer to different sites by replacing the replaceable part adapted to the water pipe connector, thereby improving the convenience of using the mixer.

[0026] The fixing portion includes a tapered thread head 1 and a connecting portion that is snapped into the inner cavity of the tapered thread head 1. The connecting portion includes a faucet inner core 2 and a connecting male head 6 connected to the faucet inner core 2. The inner cavity of the tapered thread head 1 is provided with an inner groove that adapts to the faucet inner core 2. The inner wall of the inner groove is evenly provided with four sealing grooves, and a sealing ring 11 is installed in the sealing groove. The provision of the sealing ring 11 can improve the sealing between the connecting portion and the tapered thread head 1. The sealing ring 11 is a high-temperature resistant sealing ring, and the sealing ring 11 can be made of a high-temperature resistant sealing ring containing copper powder.

[0027] The outer ring of the faucet inner core 2 is provided with two groups of bearings 3 and a sealing gasket 5. An oil seal 4 is provided on the side of the bearing 3 away from the sealing ring 2 11. The oil seal 4 is fixedly connected to the outer ring of the faucet inner core 2. The sealing gasket 5 is located between the two groups of bearings 3. The sealing gasket 5 can play a separating role to prevent the two bearings 3 from running into each other.

[0028] A limiting groove is provided between the faucet inner core 2 and the bearing 3 away from the connecting male head 6, and a retaining spring 18 is installed in the limiting groove to prevent the bearing from falling off.

[0029] The outer ring of the faucet inner core 2 is movably connected with a fixed baffle 9, which is located between the bearing 3 near the connecting male head 6 and the connecting male head 6. The outer diameters of the bearing 3, oil seal 4, sealing gasket 5 and fixed baffle 9 are the same. The inner diameter of the fixed baffle 9 is larger than the outer diameter of the connecting male head 6, which facilitates the disassembly and assembly of the fixed baffle 9. A handle 7 is provided at the other end of the connecting male head 6, and two sealing rings 8 are provided in the handle 7. The connecting male head 6 is connected to the replaceable part by a pin 14, and the sealing ring 8 is used to improve the sealing between the connecting male head 6 and the replaceable part.

[0030] A retaining spring groove 12 is provided at the bottom end of the inner cavity of the tapered thread head 1, and a retaining spring 2 10 is clamped in the inner cavity of the retaining spring groove 12. When the connecting part is installed in the tapered thread head 1, the end of the connecting part away from the connecting male head 6 is located in the inner groove. The retaining spring 2 10 is separated from the oil seal 4 close to the connecting male head 6 by the fixed baffle 9. The fixed baffle 9 fits tightly with the oil seal 4 close to the connecting male head 6 and the retaining spring 2 10. The inner diameter of the retaining spring 2 10 is smaller than the outer diameter of the fixed baffle 9. The retaining spring 2 10 can limit the connecting part so that the connecting part is fixed to the tapered thread head 1, thereby preventing the connecting part from falling off and improving the reliability of the fixed part.

[0031] The size of the fixed baffle 9 and the size of the retaining spring 10 can be set according to the needs and are not limited here.

[0032] The arrangement of the first and second retaining springs 18 and 10 provides sealing and pressure resistance, thereby increasing the wear resistance of the structure, extending the service life of the mixer, ensuring that the mixer can work continuously without water leakage, and improving work efficiency.

[0033] The front end of the tapered thread head 1 is hexagonal, which makes it easier to disassemble with a wrench. In addition, the tapered thread head designed here can increase the firmness of the mixer connection.

[0034] To summarize: when using the mixer, the user replaces the corresponding replaceable part according to the site water pipe connector, and uses the mixer to connect the water pipe and the drill pipe, making it easier for the water pipe to inject water into the drill pipe. During use, the four sealing rings 11 can seal the contact surface between the inner core of the faucet and the tapered thread head, and the two sealing rings 8 can seal the replaceable part and the connecting male head 6, preventing water leakage from the mixer and facilitating the use of the mixer. In addition, the retaining spring 10 can limit the connection part to prevent the connection part from separating from the tapered thread head 1, thereby improving the reliability of the mixer.

[0035] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology and will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and modifications can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
