[0075] The mouth is the beginning of the digestive tract of the human body, and it deeply participates in the whole digestive process by chewing food with teeth, which is essential for nutrient intake. Therefore, oral health is not only a part of human health, but also closely related to it. Common oral problems include dental calculus, periodontal disease, bacterial infection, tooth loss, etc. Clinically, various treatment methods are used to reduce or even eliminate the negative effects of these oral problems. Laser oral treatment instrument is a common device for solving the above-mentioned oral problems.

[0076] The laser oral treatment instrument is an instrument for oral treatment by using high-energy laser beams. The laser oral treatment instrument of the prior art at least includes a YAG laser, a light transmission assembly, and a light emitting tip. The YAG laser and the light emitting tip are separate structures and are optically connected by the light transmission assembly.

High-energy laser beams are used to irradiate oral tissues, which can be used for decontamination and sterilization of the oral cavity, soft and hard tissue cutting, bone tissue removal, etc. It can reduce inflammatory reactions and promote the regeneration and repair of oral tissues.

[0077] The laser oral treatment instrument of the prior art can meet the basic treatment needs, but due to the unreasonable structure, it has the problems of low integration, difficulty in moving, and inconvenience in operation.

[0078] As shown in Figures 1 to 13 To solve the above problems, the utility model provides a kind of laser oral treatment instrument, including treatment instrument body 1, laser generation component 2, water gas nozzle component 3 and gas-liquid electricity external component 4.Treatment instrument body 1 includes support outer shell and support inner shell, the support outer shell is set in the support inner shell, and the two cooperate to mainly play the role of structural support, laser generation component 2, water gas nozzle component 3 and gas-liquid electricity external component 4 are directly or indirectly arranged on support outer shell or support inner shell.Laser generation component 2 is used to generate high-energy laser beams to implement oral treatment by high-energy laser beams.Water gas nozzle component 3 is used to form water gas spray to clean or cool the oral cavity.Gas-liquid electricity external component 4 is used to connect external gas, water and electrical signals to ensure the normal operation of the laser oral treatment instrument.

[0079] As shown in Figure 5As shown, the laser generating assembly 2 comprises a quartz glass tube 201, a luminescent crystal 202, a pumping flash lamp 203, a total reflection light collecting layer 204 and a refractive mirror assembly 205. The quartz glass tube 201 is provided with a first fixed pipe 206 and a second fixed pipe 207; the luminescent crystal 202 is fixedly arranged in the first fixed pipe 206, the luminescent crystal 202 is provided with a laser working medium, one end of the luminescent crystal 202 is provided with a total reflection end face, and the other end of the luminescent crystal 202 is provided with a semi-transparent end face; the pumping flash lamp 203 is fixedly arranged in the second fixed pipe 207; the total reflection light collecting layer 204 is arranged on the outside of the quartz glass tube 201; the quartz glass tube 201 is fixedly arranged in the support inner shell, and the refractive mirror assembly 205 is fixedly arranged on the support outer shell. The working principle of the laser generating assembly 2 is as follows: in the quartz glass tube 201, the pumping flash lamp 203 emits light in a flashing manner, the light emitted by the pumping flash lamp 203 irradiates the luminescent crystal 202, the laser working medium in the luminescent crystal 202 is excited to emit laser, at this time, the laser is emitted in various directions, the laser emitted in various directions is limited in the total reflection light collecting layer 204, oscillates between the total reflection end face and the semi-transparent end face of the luminescent crystal 202, and finally forms a high-energy laser beam with consistent direction, which is emitted from the semi-transparent end face. The laser generated by the cooperation of the pumping flash lamp 203 and the luminescent crystal 202 is emitted from the semi-transparent end face, refracted by the refractive mirror assembly 205, and then emitted from the laser emitting tip 303.

[0080] The water and gas jet assembly 3 comprises a water and gas jet body 301, a tip fixing insert 302 and a laser emitting tip 303; the water and gas jet body 301 is sleeved on the support outer shell, the water and gas jet body 301 is provided with a first mounting sleeve, the first mounting sleeve is located in the center of the water and gas jet body 301 and arranged in the axial direction, the side wall of the water and gas jet body 301 is provided with a water conveying pipe, a gas conveying pipe and a water and gas emitting hole, the water conveying pipe and the gas conveying pipe are respectively communicated with the water and gas emitting hole; the tip fixing insert 302 is fixedly arranged in the first mounting sleeve, the tip fixing insert 302 is provided with a second mounting sleeve, the second mounting sleeve is located in the center of the tip fixing insert 302 and arranged in the axial direction; the laser emitting tip 303 is fixedly arranged in the second mounting sleeve.

[0081] The laser exit tip 303 is embedded with an optical fiber, both ends of the optical fiber are exposed to both ends of the laser exit tip 303, and the water and gas exit hole is oriented in the same direction as the laser exit tip 303. The optical fiber is distributed along the length direction of the laser exit tip 303, and the water and gas exit hole is oriented in the same direction as the laser exit tip 303. After the laser enters the optical fiber from one end of the optical fiber, it is transmitted to the other end of the optical fiber. Since both ends of the optical fiber are exposed to both ends of the laser exit tip 303, the high-energy laser beam will eventually exit from the laser exit tip 303. The operator can perform various treatments on the patient's oral cavity based on this. In this process, the water and gas spray ejected from the water and gas exit hole can cool and clean the patient's oral cavity.

[0082] The gas-liquid-electric external connection assembly 4 includes a connector fixing sleeve 401 and a gas-liquid-electric connection component 402.

The electric delivery plugs 404 are connected to the light-emitting crystal 202 and the pump flash lamp 203 through conductive cables. The water delivery pipes and the gas delivery pipes are ordinary hose structures.

[0083] Gas and liquid are both fluids. After the gas and / or liquid from the outside are connected through the gas-liquid delivery plugs 403, the gas enters the gas delivery pipe and the liquid enters the water delivery pipe. The gas is connected to the gas delivery pipe in the water and gas spray head body 301, and the liquid is connected to the water delivery pipe in the water and gas spray head body 301. The gas and liquid are mixed in the water and gas spray head body 301 and then sprayed out, which can cool and clean the patient's oral cavity. In this technical solution, the liquid used for cooling is usually water.

[0084] When the laser oral treatment instrument is used for treatment, the working process is as follows: the laser generating assembly 2 generates laser and forms a high-energy laser beam. The operator can use the high-energy laser beam to perform decontamination and sterilization, soft and hard tissue cutting, bone tissue removal, etc. on the patient's oral cavity. During the operation, the irradiated part may generate assembly debris and overheat. At this time, the water and gas spray ejected by the water and gas spray head assembly 3 can clean and cool the corresponding part. Therefore, based on the above technical solution, the laser generating assembly 2, the water and gas spray head assembly 3, and the gas-liquid-electric external connection assembly 4 are arranged in the treatment instrument body 1. The laser generating and exiting function and the water and gas mixing and cooling function are integrated into one structure, which meets the basic operation requirements of decontamination and sterilization, soft and hard tissue cutting, bone tissue removal, etc. and has the advantages of high integration, reasonable structure, and easy operation.

The existing technology is to form a support outer shell by a front shell and a rear shell, and the present technical solution does not make innovative research on this point and does not expand the description in combination with the drawings. In addition, in analyzing the present technical solution, the laser emission direction is taken as the reference, the front shell and the quick release sleeve are in front, and the rear shell and the quick release plug are in back.

[0086] The quick release sleeve 5 is provided with an elastic clamping assembly, the quick release plug 6 is provided with a clamping matching assembly, and the quick release plug 6 is detachably inserted into the quick release sleeve 5 through the cooperation of the elastic clamping assembly and the clamping matching assembly. In the present technical solution, the quick release plug 6 and the water and gas spray head body 301 are generally inserted into the quick release sleeve 5 through the "dark pipe" provided in the side wall and cooperate with other structures to achieve the technical purpose of transmitting water and gas from back to front.

[0087] Based on the above structure, under the premise that the quick release sleeve 5 and the quick release plug 6 are fixedly arranged in the front shell and the rear shell respectively, the elastic clamping assembly and the clamping matching assembly are provided, the quick release plug 6 is detachably inserted into the quick release sleeve 5 through the cooperation of the elastic clamping assembly and the clamping matching assembly, the quick release sleeve 5 and the quick release plug 6 are mutually inserted and fixed when needed for use to emit laser for treatment, and the quick release sleeve 5 and the quick release plug 6 are mutually separated when needed for disinfection to meet the fixing or dismounting requirements before and after use, so that the operator can assemble the water and gas spray head assembly 3 through the cooperation of the quick release sleeve 5 and the quick release plug 6 during normal use, and can also disassemble and disinfect after use, thereby effectively preventing cross infection.

[0088] As Figure 3 and Figure 4As shown, preferably, the elastic clamping assembly comprises an elastic clamping hoop 501 and three hard balls 502, the elastic clamping hoop 501 is formed by bending a metal long sheet into a circular arc structure. The elastic clamping hoop 501 is provided with three ball positioning through holes 503; among the three ball positioning through holes 503, one is a circular through hole, and the other two are elongated through holes, the circular through hole is located at the midpoint of the elastic clamping hoop 501, and the two elongated through holes are symmetrically arranged on both sides of the circular through hole. The elastic clamping hoop 501 is formed by bending a metal long sheet into a circular arc structure, and the two ends of the metal long sheet form an opening. Here, the opening means that the head and tail are not connected, and the metal long sheet does not form a closed circle. When the metal long sheet is bent into a circular arc structure and the head and tail are not connected, the metal long sheet itself will have elasticity, that is, when the circular arc structure is subjected to external force, the elastic force will drive it to return to the original state. The technical solution utilizes the characteristics of the elastic clamping hoop to provide the elastic force required for quick disassembly.

[0089] The side wall of the quick release sleeve 5 is provided with three ball movable through holes 504, which are arranged through the side wall of the quick release sleeve 5; the bottom of the ball movable through hole 504 is provided with a ball limiting ring 505, the ball limiting ring 505 is located on the inner side of the side wall of the quick release sleeve 5, the inner diameter of the ball limiting ring 505 is smaller than the radius of the hard ball 502; the hard ball 502, the ball movable through hole 504 and the ball positioning through hole 503 correspond one by one; the hard ball 502 is movably arranged in the ball movable through hole 504, and the two sides of the hard ball 502 abut against the ball positioning through hole 503 and the ball limiting ring 505 respectively; the elastic clamping hoop 501 is sleeved outside the quick release sleeve 5, and the elastic clamping hoop 501 applies elastic force to the plurality of hard balls 502 towards the axial direction of the quick release sleeve 5; the clamping and matching assembly is a ball clamping groove 601 arranged on the quick release plug 6, and the ball clamping groove 601 is arranged on the outer side of the quick release plug 6 in the circumferential direction.

[0090] When the quick release plug 6 is fixed on the quick release sleeve 5, the elastic clamping hoop 501 fixes the hard ball 502 in the ball clamping groove 601; when the quick release plug 6 and the quick release sleeve 5 move relatively under external force, the hard ball 502 is forced to open the elastic clamping hoop 501 and slide out of the ball clamping groove 601.

[0091] In combination with the above structure, the working principle of the quick disassembly structure is analyzed as follows: when the quick release plug 6 is fixed on the quick release sleeve 5, the elastic clamp 501 uses its own elastic force to fix the hard ball 502 in the ball clamping groove 601, and correspondingly, the quick release plug 6 and the quick release sleeve 5 are combined into an integral structure. When it is necessary to separate the quick release plug 6 and the quick release sleeve 5 to achieve quick disassembly, an external force is provided by the operator to make the quick release plug 6 and the quick release sleeve 5 form a trend of mutual separation, at this time, the external force will drive the hard ball 502 to slide out of the ball clamping groove 601, in this process, the hard ball 502 expands the elastic clamp 501 and gradually slides out of the ball clamping groove 601 by overcoming the elastic force of the elastic clamp 501, after the hard ball 502 leaves the ball clamping groove 601, the quick release plug 6 and the quick release sleeve 5 are separated from each other. When it is necessary to quickly install the quick release plug 6 on the quick release sleeve 5, an external force is provided by the operator to make the quick release plug 6 and the quick release sleeve 5 form a trend of mutual insertion, in this process, the hard ball 502 expands the elastic clamp 501 and gradually embeds in the ball clamping groove 601 by overcoming the elastic force of the elastic clamp 501, after the hard ball 502 embeds in the ball clamping groove 601, the quick release plug 6 and the quick release sleeve 5 are inserted and fixed to each other.

[0092] Based on the above structure, the metal long piece is bent to a circular arc structure and an opening is formed on the circular arc structure, the metal long piece uses its own elasticity to form an elastic clamp 501, and a plurality of hard balls 502 are pressed into the ball clamping groove 601. When not subjected to external force, the hard ball 502 is engaged in the ball clamping groove 601, and when subjected to external force, it can roll out of the ball clamping groove 601. An elastic clamping assembly is formed by one elastic clamp 501 and three hard balls 502, a clamping and matching assembly is formed by recessing inwardly on the quick release plug 6 to obtain the ball clamping groove 601, and a simple elastic structure is used to achieve the function of quick disassembly.

[0097] Based on the above structure, the quartz glass tube 201, the light-emitting crystal 202, the pump flash lamp 203 and other components are fixed in the support inner shell formed by the front inner support assembly 101, the rear inner support assembly 102 and the laser cavity support cylinder 103, and the support inner shell is further closed by cooperating with the support sealing ring, which can provide structural support for the internal cooling water circulation.

[0098] As shown in Figure 8 , preferably, the gasket compression piece 108 includes a compression sleeve 109, a first fixing ear 110 and a second fixing ear 111, and the first fixing ear 110 and the second fixing ear 111 are fixedly arranged on both sides of the compression sleeve 109.

[0100] Based on the above structure, the gasket compression piece 108 is formed by the compression sleeve 109, the first fixing ear 110 and the second fixing ear 111, and the support sealing ring is compressed in the gasket fixing sleeve by the gasket compression piece 108, which can effectively improve the sealing performance.

[0101] As shown in Figure 2 , Figure 5 , Figure 6 , Figure 7As shown, preferably, a cooling liquid flow connection hole is arranged between the crystal front end fixed through hole 104 and the flash lamp front end fixed through hole 105; the rear internal support assembly 102 is further provided with a first external connecting pipe 112 and a second external connecting pipe 113, the first external connecting pipe 112 and the second external connecting pipe 113 are respectively connected with the water delivery pipe of the gas-liquid electric external connecting assembly 4, the first external connecting pipe 112 is connected with the crystal rear end fixed through hole 106, and the second external connecting pipe 113 is connected with the flash lamp rear end fixed through hole 107; the two ends of the quartz glass pipe 201 are respectively abutted on the front internal support assembly 101 and the rear internal support assembly 102, the two ends of the first fixed pipe 206 are respectively connected with the crystal front end fixed through hole 104 and the crystal rear end fixed through hole 106, and the two ends of the second fixed pipe 207 are respectively connected with the flash lamp front end fixed through hole 105 and the flash lamp rear end fixed through hole 107; liquid flow gaps are formed between the luminescent crystal 202 and the first fixed pipe 206 and between the pump flash lamp 203 and the second fixed pipe 207.

[0102] Briefly, the luminescent crystal 202 is fixedly arranged in the first fixed pipe 206, and the two ends of the luminescent crystal 202 are respectively fixed in the crystal front end fixed through hole 104 and the crystal rear end fixed through hole 106; the pump flash lamp 203 is fixedly arranged in the second fixed pipe 207, and the two ends of the pump flash lamp 203 are respectively fixed in the flash lamp front end fixed through hole 105 and the flash lamp rear end fixed through hole 107.

[0103] A liquid cooling pipe is formed from the first external connecting pipe 112, the crystal rear end fixed through hole 106, the first fixed pipe 206, the crystal front end fixed through hole 104, the cooling liquid flow connection hole, the flash lamp front end fixed through hole 105, the second fixed pipe 207, the flash lamp rear end fixed through hole 107 and the second external connecting pipe 113 in sequence, and the liquid cooling pipe is a U-shaped pipe.

[0104] In the working process, the luminescent crystal 202 and the pump flash lamp 203 cooperate to generate laser and inevitably generate heat, the liquid cooling pipe is connected with the external cooling liquid through the first external connecting pipe 112 and the second external connecting pipe 113, the cooling liquid can enter the liquid cooling pipe through the first external connecting pipe 112 and then be discharged from the second external connecting pipe 113, or the cooling liquid can enter the liquid cooling pipe through the second external connecting pipe 113 and then be discharged from the first external connecting pipe 112, and the cooling liquid fully contacts the luminescent crystal 202 and the pump flash lamp 203 when flowing in the first fixed pipe 206 and the second fixed pipe 207, so that the luminescent crystal 202 and the pump flash lamp 203 are cooled. In the technical solution, water is mostly used as the cooling liquid.

[0105] Based on the above structure, the first fixed pipe 206 and the second fixed pipe 207 on the quartz glass tube 201 are used as the basis to build the cooling pipe, and the cooling liquid flows through the through hole to connect the through hole between the front end fixed through hole 104 of the crystal and the front end fixed through hole 105 of the flash lamp, and the first external pipe 112 and the second external pipe 113 are externally connected to the water pipe on the rear internal support assembly 102, so that the heat generated in the working process of the laser device can be timely and efficiently taken away, overheating is effectively prevented, and normal operation of the equipment is ensured.

[0106] As shown in Figure 9 The outer side of the water and gas spray head body 301 is preferably outwardly convex to form a first plug gasket fixing portion 602, a second plug gasket fixing portion 603, and a third plug gasket fixing portion 604. The first plug gasket fixing portion 602, the second plug gasket fixing portion 603, and the third plug gasket fixing portion 604 are formed on the outer side of the water and gas spray head body 301 along the circumference of the water and gas spray head body 301, that is, the first plug gasket fixing portion 602, the second plug gasket fixing portion 603, and the third plug gasket fixing portion 604 form a similar ring structure on the outer side of the water and gas spray head body 301. The first plug gasket fixing portion 602, the second plug gasket fixing portion 603, and the third plug gasket fixing portion 604 are equally distributed along the axial direction of the water and gas spray head body 301, that is, along the length direction of the water and gas spray head body 301, the distance between the first plug gasket fixing portion 602 and the second plug gasket fixing portion 603 is equal to the distance between the second plug gasket fixing portion 603 and the third plug gasket fixing portion 604. The first plug gasket fixing portion 602, the second plug gasket fixing portion 603, and the third plug gasket fixing portion 604 are respectively fixedly provided with a spray head sealing ring 605, and the sealing performance of the device is improved based on the spray head sealing ring 605.

[0107] Another function of the first plug gasket fixing portion 602, the second plug gasket fixing portion 603, and the third plug gasket fixing portion 604 is to fix the spray head sealing ring 605. When the water and gas spray head body 301 is sleeved in the therapeutic instrument shell, the water and gas spray head body 301 abuts against the therapeutic instrument shell through the spray head sealing ring 605 on the first plug gasket fixing portion 602, the second plug gasket fixing portion 603, and the third plug gasket fixing portion 604.

[0108] Based on the above structure, the sealing ring 605 on the first plug gasket fixing part 602, the second plug gasket fixing part 603 and the third plug gasket fixing part 604 abuts in the therapeutic instrument shell, which can effectively ensure the sealing between the water and gas spray head body 301 and the therapeutic instrument shell, and prevent water leakage from affecting electronic components. By providing three plug gasket fixing parts, three sealing rings 605 can greatly improve the sealing effect.

[0109] One of the functions of the first plug gasket fixing part 602, the second plug gasket fixing part 603 and the third plug gasket fixing part 604 is to form a liquid channel and a gas channel. The water and gas spray head body 301 forms the liquid channel by the sealing ring 605 on the first plug gasket fixing part 602 and the second plug gasket fixing part 603 abutting in the therapeutic instrument shell; the water and gas spray head body 301 forms the gas channel by the sealing ring 605 on the second plug gasket fixing part 603 and the third plug gasket fixing part 604 abutting in the therapeutic instrument shell.

[0110] The first plug gasket fixing part 602, the second plug gasket fixing part 603 and the third plug gasket fixing part 604 are protrusions on the outer side of the water and gas spray head body 301. When the water and gas spray head body 301 is fitted on the therapeutic instrument shell, the sealing ring 605 on the first plug gasket fixing part 602, the second plug gasket fixing part 603 and the third plug gasket fixing part 604 abuts in the therapeutic instrument shell. Accordingly, a sealed channel is formed between the water and gas spray head body 301, the first plug gasket fixing part 602, the second plug gasket fixing part 603 and the therapeutic instrument shell, which serves as a liquid channel; a sealed channel is formed between the water and gas spray head body 301, the second plug gasket fixing part 603, the third plug gasket fixing part 604 and the therapeutic instrument shell, which serves as a gas channel.

[0111] Based on the above structure, in combination with the cooperation between the water and gas spray head body 301 and the therapeutic instrument shell, the sealing ring 605 on the first plug gasket fixing part 602 and the second plug gasket fixing part 603 forms a liquid channel, and the sealing ring 605 on the second plug gasket fixing part 603 and the third plug gasket fixing part 604 forms a gas channel. The first plug gasket fixing part 602, the second plug gasket fixing part 603 and the third plug gasket fixing part 604, which are originally used for sealing and isolation, are ingeniously divided into a liquid channel and a gas channel, further simplifying the structure of the water and gas mixed spray head.

[0112] As Figure 10As shown, preferably, one end of the support outer shell is provided with a hose socket 114; a wire tube protection hose 7 is sleeved on the hose socket 114, the water pipe, the gas pipe and the conductive cable are arranged in the wire tube protection hose 7, the length of the wire tube protection hose 7 is greater than the length of the water pipe, the length of the gas pipe and the length of the conductive cable; the wire tube protection hose 7 is sleeved with a hose crimping ring 115, the hose crimping ring 115 crimps the wire tube protection hose 7 on the hose socket 114; the support outer shell is provided with a hose crimping outer sleeve 116, the hose crimping outer sleeve 116 is provided with an internal thread connection part, the hose crimping outer sleeve 116 is threadedly connected with the external thread connection part on the support outer shell through the internal thread connection part thereon, and the hose crimping outer sleeve 116 fixes the hose crimping ring 115 between the support outer shell and the hose crimping outer sleeve 116.

[0113] The hose socket 114, the wire tube protection hose 7, the hose crimping ring 115 and the hose crimping outer sleeve 116 form a wire tube anti-pulling structure in the technical solution, during installation, the deformable characteristic of the wire tube protection hose 7 is utilized to first sleeve the wire tube protection hose 7 into the hose socket 114 on the support outer shell, then sleeve the wire tube protection hose 7 into the hose crimping ring 115, and then utilize the external thread connection part and the internal thread connection part to assemble the hose crimping outer sleeve 116 on the support outer shell, at this time, the hose crimping ring 115 crimps the wire tube protection hose 7 on the hose socket 114, and the support outer shell and the hose crimping outer sleeve 116 limit the hose crimping ring 115 therebetween, thereby ensuring the crimping and fixing effect of the hose crimping ring 115 on the wire tube protection hose 7.

[0114] Since the length of the wire tube protection hose 7 is greater than the length of the cable and the length of the water pipe, when the cable and the water pipe are subjected to external pulling force, the pulling force will act on the wire tube protection hose 7, and since the wire tube protection hose 7 is fixed on the hose socket 114, the pulling force will not be transmitted to the cable and the water pipe.

[0115] Based on the above structure, the wire tube protection hose 7 is sleeved on the hose socket 114, the hose crimping ring 115 is sleeved on the wire tube protection hose 7, and the hose crimping outer sleeve 116 is assembled on the support outer shell, so that the position of the hose crimping ring 115 can be limited, thereby fixing the end of the wire tube protection hose 7 by the hose crimping ring 115, ensuring the operation freedom and realizing the anti-pulling function by a simple structure.

[0116] As shown in the drawings, Figure 11As shown, preferably, the hose sleeve 114 comprises a first clamping cylindrical sleeve 117, a first clamping circular truncated cone sleeve 118, a second clamping cylindrical sleeve 119 and a second clamping circular truncated cone sleeve 120, which are coaxial with each other; the first clamping cylindrical sleeve 117 is located at one end away from the support outer shell, the second clamping circular truncated cone sleeve 120 is located at one end close to the support outer shell, the first clamping cylindrical sleeve 117, the first clamping circular truncated cone sleeve 118, the second clamping cylindrical sleeve 119 and the second clamping circular truncated cone sleeve 120 are sequentially connected end to end, and a hose clamping step is formed between the second clamping cylindrical sleeve 119 and the second clamping circular truncated cone sleeve 120.

[0117] The hose sleeve 114 is used to sleeve the wire tube protection hose 7 and is fixed with the wire tube protection hose 7 in cooperation with the hose crimping ring 115. Based on the above structure, the hose sleeve 114 is divided into the first clamping cylindrical sleeve 117, the first clamping circular truncated cone sleeve 118, the second clamping cylindrical sleeve 119 and the second clamping circular truncated cone sleeve 120, and the hose clamping step is formed between the second clamping cylindrical sleeve 119 and the second clamping circular truncated cone sleeve 120. When the wire tube protection hose 7 is crimped on the hose clamping step by the hose crimping ring 115, the hose clamping step will cause the wire tube protection hose 7 to deform, which will make the fixing effect of the wire tube protection hose 7 better.

[0118] As described above, the hose sleeve 114 is used to sleeve the wire tube protection hose 7. The outer diameter of the first clamping cylindrical sleeve 117 is smaller than that of the second clamping cylindrical sleeve 119, and a guide inclined part is formed between the first clamping cylindrical sleeve 117 and the second clamping cylindrical sleeve 119 by the outer sidewall of the first clamping circular truncated cone sleeve 118.

[0119] The guide inclined part is formed by the outer sidewall of the first clamping circular truncated cone sleeve 118. In the process of sleeving the wire tube protection hose 7, the slope formed by the guide inclined part can smoothly send the wire tube protection hose 7 into the hose sleeve 114 and sleeve it, which facilitates sleeving the wire tube protection hose 7 on the hose sleeve 114 during assembly.

The gas-liquid delivery connectors 403 and the electrical delivery connectors 404 are sleeved on the connector fixing sleeve 401, and the water pipe, the gas pipe, and the conductive cable are respectively passed through the connector fixing sleeve 401.

[0122] Its function is to fix the gas-liquid transmission connector 403, the electrical transmission connector 404, and transmission pipes such as water pipes, gas pipes, and conductive cables inside it. For example, when a connector corresponds to an electrical transmission connector 404, a part of the electrical transmission connector 404 will be inserted into it, and a part of the conductive cable connected to the electrical transmission connector 404 will also be inserted into it. In general, the transmission connectors and transmission pipes have a one-to-one correspondence.

[0123] The connector fixing plate 407 serves to fix multiple gas-liquid delivery connectors 403 and multiple electrical delivery connectors 404, and is fixed to the connector fixing sleeve 401 via the connector fixing part, forming the basic plug structure of this gas-liquid-electric external connection assembly. The connector fixing plate 407 is set on the connector fixing sleeve 401 through the inwardly recessed connector fixing part, and then, by covering the gas-liquid delivery connectors 403, electrical delivery connectors 404, and corresponding water pipes, gas pipes, and conductive cables, it connects with the outside through the two types of connectors, so as to transmit external liquids, gases, or electrical signals into this device.

[0125] During plugging, one end of the connecting piece fixing sleeve 401 is connected with the gas-liquid conveying plug-in connector 403 and the electric conveying plug-in connector 404 on the gas-liquid-electric connecting part 402 and the external setting is connected. Compared with the prior art which needs to be provided with a water connector, a liquid connector and an electric connector, the structure in the technical solution is more simple and effective: after a plurality of gas-liquid conveying plug-in connectors 403 and a plurality of electric conveying plug-in connectors 404 are arranged on the gas-liquid-electric connecting part 402, the pipeline and the cable are collected by the cable fixing sleeve 405, and an integral structure is formed with the connecting piece fixing sleeve 401 and the joint outer sleeve 406, so that the functions of electric signal, liquid and gas connection are integrated based on the simple structure. Simply speaking, the gas-liquid-electric external device provided by the device is a device capable of simultaneously meeting the connection of electric signal, liquid and gas between different devices.
