Abstract
Description
Technical Field
[0001] The invention relates to the technical field of dental chair hoses, and in particular to a dental chair hose capable of preventing collapse. Background Art
[0002] Among oral medical equipment, various hoses on the dental chair play a vital role in dental treatment. They are mainly used to connect the saliva suction system of the dental chair so that saliva, blood and other debris in the patient's mouth can be sucked away in time during oral treatment, thereby maintaining a clear surgical field of view.
[0003] However, during dental diagnosis and treatment, the hoses on the dental chair need to be bent and squeezed to adapt to treatment needs at different angles and depths. However, existing hoses are prone to collapse when bent frequently or subjected to external pressure, resulting in failure of the transmission function, which in turn affects the doctor's operation and the patient's comfort.
[0004] To this end, the present invention provides a hose for a dental chair that prevents collapse. Summary of the invention
[0005] In order to make up for the deficiencies of the prior art and solve the technical problems raised in the background technology.
[0006] The present invention provides a hose for a dental chair that prevents collapse, comprising a hose support portion and a hose movable portion, the hose support portion comprising a first connecting strip, the inner side and outer side of the bottom of the first connecting strip being fixedly connected to a first inner wall and a first outer wall respectively, the hose movable portion comprising a second connecting strip, the inner side and outer side of the bottom of the second connecting strip being fixedly connected to a second inner wall and a second outer wall respectively, the hose support portion and the hose movable portion being connected end to end to form a hose unit, a plurality of hose units being connected end to end to form a hose body, and a cavity with a fixed internal gas volume being formed at the top of the connection between the hose support portion and the hose movable portion.
[0007] Furthermore, the hose support portion also includes a filling ring for support, which is located in the cavity formed by the bottom of the first connecting strip and the top of the second connecting strip, and the height of the filling ring is matched with the height tolerance between the bottom of the first connecting strip and the top of the second connecting strip.
[0008] Furthermore, a protective component is also provided on the inner side of the hose support portion, and there are two groups of protective components, each of which includes an antagonistic component and a base component, the antagonistic component is slidably connected to the base component, and the sides of the two antagonistic components away from the base component are respectively fixedly connected to the two sides of the middle part of the filling ring, and the sides of the two base components away from the antagonistic components are respectively fixedly connected to the inner side of the first outer wall and the outer side of the first inner wall.
[0009] Furthermore, the counter-assembly includes a movable ring, a side of the movable ring away from the filling ring is fixedly connected to a limiting ring, a side of the limiting ring away from the filling ring is fixedly connected to an elastic rubber block, the base assembly includes a base body, a side of the base body close to the filling ring is provided with a limiting groove that matches the tolerance of the movable ring, a side of the limiting groove away from the filling ring is provided with a movable groove that matches the tolerance of the limiting ring, and the side of the elastic rubber block away from the filling ring is fixedly connected to the inner wall of the movable groove away from the filling ring.
[0010] Furthermore, a buffer assembly is provided on the inner side of the hose support portion, and the buffer assembly includes a buffer ring and a stretch ring. Springs are fixedly connected on all four sides of the outer side of the buffer ring. The side of the spring away from the buffer ring is fixedly connected to the first inner wall, and the bottom of the buffer ring is fixedly connected to the top of the stretch ring.
[0011] Furthermore, the height of the buffer ring, the height of the stretch ring, the height of the hose support portion and the height of the hose movable portion are all the same.
[0012] Furthermore, the filling ring is made of hard plastic.
[0013] Furthermore, the stretch ring is made of natural rubber.
[0014] The beneficial effects of the present invention are: 1. The present invention is provided with a hose support part and a hose movable part. The hose support part and the hose movable part are connected end to end to form a hose unit. Different numbers of hose units are customized according to the specifications of the dental chair and are spliced end to end to form a hose body to meet the requirements of hoses of different lengths. The top of the connection between the hose support part and the hose movable part forms a cavity with a fixed internal gas volume. When the operator actively bends the hose body, the air in the cavity is squeezed and moves, ensuring that the hose support part and the hose movable part are uniformly stressed. When the operator releases the hose body, the air in the cavity loses its squeezing and drives the hose body to reset. Since a filling ring is also provided on the inner side of the hose support part, the filling ring is made of hard plastic, and the stress area of the filling ring is deformed during the bending and squeezing process to adapt to the bending process of the hose body. During the resetting process of the hose body, the filling ring is reset due to its own elastic potential energy to assist the hose to return to its original state, ensuring that the hose can automatically restore to its initial state after the force is released after bending and pressing the hose, thereby avoiding the collapse of the hose when it is in a bent state for a long time.
[0015] 2. The present invention is provided with a protective component. When the filling ring is bent, the counter component is displaced by the bending deformation of the filling ring, and the elastic rubber block resists the filling ring. During the bending process of the operator, a certain resistance is added to avoid excessive bending, which is conducive to more accurate control of subtle position changes. When the operator releases the hose, the elastic rubber block further assists in resetting the hose.
[0016] 3. The present invention is provided with a buffer component. When the hose is used to suck saliva, since the impact force of the inner wall of the curved pipe on the inner wall of the turning point is greater than that of the inner wall of the straight pipe, the spring can buffer the impact force, protect the second inner wall and the first inner wall to avoid the inner pipe from rupture, and when the hose body is bent, the stretching ring can cooperate with the hose support part and the hose movable part to stretch and squeeze.

[0019] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.
[0020] like Figures 1 to 6 As shown, a hose for a dental chair that prevents collapse according to an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , comprising a hose support portion 1 and a hose movable portion 2, the hose support portion 1 comprising a first connecting strip 101, the inner side and the outer side of the bottom of the first connecting strip 101 are respectively fixedly connected with a first inner wall 103 and a first outer wall 102, the hose movable portion 2 comprising a second connecting strip 201, the inner side and the outer side of the bottom of the second connecting strip 201 are respectively fixedly connected with a second inner wall 203 and a second outer wall 202, the two sides of the top of the second connecting strip 201 are respectively fixedly connected with the bottom of the first inner wall 103 and the first outer wall 102, the hose support portion 1 and the hose movable portion 2 are connected end to end to form a hose unit, a plurality of hose units are connected end to end to form a hose body, and a cavity with a fixed internal gas volume is formed at the top of the connection between the hose support portion 1 and the hose movable portion 2; Specifically, the hose support part 1 and the hose movable part 2 are connected end to end to form a hose unit. Different numbers of hose units are customized according to the specifications of the dental chair and spliced end to end to form a hose body to meet the requirements of hoses of different lengths. The top of the connection between the hose support part 1 and the hose movable part 2 forms a cavity with a fixed internal gas volume. When the operator actively bends the hose body, the air in the cavity is squeezed and moves, ensuring that the hose support part 1 and the hose movable part 2 are evenly stressed. When the operator loosens the hose body, the air in the cavity loses its squeezing, driving the hose body to reset.
[0021] Please refer to Figure 2 , Figure 3 The hose support portion 1 also includes a filling ring 104 for support. The filling ring 104 is located in the cavity formed by the bottom of the first connecting strip 101 and the top of the second connecting strip 201. The height of the filling ring 104 matches the height tolerance between the bottom of the first connecting strip 101 and the top of the second connecting strip 201.
[0022] Furthermore, the filling ring 104 is made of hard plastic; Specifically, since a filling ring 104 is provided on the inner side of the hose support portion 1, the filling ring 104 is made of hard plastic, and during the bending and extrusion process, the stress-bearing area of the filling ring 104 is deformed to adapt to the bending process of the hose body. During the resetting process of the hose body, the filling ring 104 is reset due to its own elastic potential energy to assist the hose in returning to its original state, ensuring that the hose can automatically return to its initial state after the force is released after bending and pressing, thereby avoiding collapse of the hose when it is in a bent state for a long time.
[0023] Please refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 A protective assembly 3 is also provided on the inner side of the hose support portion 1. The protective assembly 3 has two groups. Each protective assembly 3 includes an antagonistic assembly 301 and a base assembly 302. The antagonistic assembly 301 is slidably connected to the base assembly 302. The two antagonistic assemblies 301 are respectively fixedly connected to the two sides of the middle of the filling ring 104 on one side away from the base assembly 302. The two base assemblies 302 are respectively fixedly connected to the inner side of the first outer wall 102 and the outer side of the first inner wall 103 on one side away from the antagonistic assembly 301. Please refer to Figure 5 , Figure 6 The counter component 301 includes a moving ring 3011, and a limiting ring 3012 is fixedly connected to the side of the moving ring 3011 away from the filling ring 104, and an elastic rubber block 3013 is fixedly connected to the side of the limiting ring 3012 away from the filling ring 104. The base component 302 includes a base body 3021, and a limiting groove 3022 matching the tolerance of the moving ring 3011 is opened on the side of the base body 3021 close to the filling ring 104, and the limiting groove 3022 is opened on the side away from the filling ring 104. There is a moving groove 3023 with a tolerance matching with the limiting ring 3012, and the side of the elastic rubber block 3013 away from the filling ring 104 is fixedly connected to the side wall of the moving groove 3023 away from the filling ring 104, and the two sides of the elastic rubber block 3013 are respectively connected to the side wall of the moving groove 3023 and the limiting ring 3012. Since the elastic rubber block 3013 itself has elastic potential energy, its length will change when it is pulled by an external force, so the antagonistic component 301 and the base component 302 can slide relative to each other within a certain degree; Specifically, when the filling ring 104 is bent, the counteracting component 301 is displaced due to the bending deformation of the filling ring 104, and the elastic rubber block 3013 resists the filling ring 104, adding a certain resistance during the bending process of the operator to avoid excessive bending, which is conducive to more precise control of subtle position changes, and when the operator releases the hose, the elastic rubber block 3013 further assists in resetting the hose.
[0024] Please refer to Figure 2 , Figure 3 , Figure 4A buffer assembly 4 is provided on the inner side of the hose support portion 1, and the buffer assembly 4 includes a buffer ring 401 and a stretching ring 403. Springs 402 are fixedly connected to the four sides of the outer side of the buffer ring 401. The side of the spring 402 away from the buffer ring 401 is fixedly connected to the first inner wall 103, and the bottom of the buffer ring 401 is fixedly connected to the top of the stretching ring 403.
[0025] Please refer to Figure 3 , the height of the buffer ring 401, the height of the stretch ring 403, the height of the hose support portion 1 and the height of the hose movable portion 2 are all the same; Specifically, when using the hose to suck saliva, since the impact force of the inner wall of the curved pipe on the inner wall of the turning point is greater than that of the inner wall of the straight pipe, the spring 402 can buffer the impact force and protect the second inner wall 203 and the first inner wall 103 to prevent the inner pipe from breaking.
[0026] Furthermore, the material of the stretch ring 403 is natural rubber; Specifically, when the hose body is bent, the stretching ring 403 can cooperate with the hose supporting part 1 and the hose movable part 2 to stretch and squeeze.
[0027] How it works The hose support part 1 and the hose movable part 2 are connected end to end to form a hose unit. Different numbers of hose units are customized according to the specifications of the dental chair and spliced end to end to form a hose body to meet the requirements of hoses of different lengths. The top of the connection between the hose support part 1 and the hose movable part 2 forms a cavity with a fixed internal gas volume. The saliva suction system is connected to the buffer component 4, and the medium transmission occurs inside the buffer component 4. When the operator actively bends the hose body: In the hose support part 1, the force-bearing area of the filling ring 104 is deformed to adapt to the bending process of the hose body, and the counteracting component 301 is displaced by the bending deformation of the filling ring 104. When the filling ring 104 is bent, one side of the moving ring 3011 is pulled and extended, and the other side is pushed to retract into the inner side of the base body 3021. The elastic rubber block 3013 has a certain degree of deformation to resist the bending degree of the filling ring 104. In the flexible hose movable portion 2, the air in the bottom cavity of the second connecting strip 201 is squeezed and moves, so that the force on the second connecting strip 201, the second outer wall 202 and the second inner wall 203 is more uniform; At this time, the stretching ring 403 stretches and squeezes the corresponding elongated and bent parts of the hose support part 1 and the hose movable part 2; When the operator releases force and loosens the hose body: In the hose support part 1, the elastic rubber block 3013 returns to its initial state, pushing the moving ring 3011 to reset. The thrust of the moving ring 3011 and the elastic potential energy of the filling ring 104 restore the filling ring 104 to a straight state. In the flexible tube movable part 2, the air in the bottom cavity of the second connecting strip 201 loses its compression, driving the flexible tube body to reset; The stretch ring 403 loses the extrusion force and resets.
[0028] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
