DETAILED DESCRIPTION

[0031] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0032] Embodiment 1:

[0033] Reference Figures 1 to 3 The present embodiment provides a dental handpiece oiler for oiling and maintaining the dental handpiece. Specifically, the dental handpiece oiler of the present embodiment comprises a three-purpose spray gun 1, a machine base 2 and an oil storage bottle 3 for storing lubricating oil, as described in detail below.

[0034] The base 2 in this embodiment is a right-angled trapezoid that is small at the top and large at the bottom, and is surrounded by a top wall, a bottom wall, two side walls, a rear wall and a panel 21 to form a hollow accommodating chamber. When in use, the bottom wall is placed on a support table. The area on the side opposite to the panel 21 in the top wall of the base 2 is recessed downward to form an oil storage bottle fixing position, and the bottom of the oil storage bottle 3 is fixed to the base 2 by bolts. Specifically, the bottom wall of the oil storage bottle 3 has two bolt holes, and the two bolt holes and the air inlet nozzle 32 and the oil outlet nozzle 33 described later are arranged in two columns and two rows, the two bolt holes are on a diagonal line, and the air inlet nozzle 32 and the oil outlet nozzle 33 are on another diagonal line. Bolts are inserted from the side of the base 2 opposite to the oil storage bottle 3 and screwed to the bolt holes, thereby fixing the oil storage bottle 3 in the oil storage bottle fixing position. Although this fixation is detachable, it is only an assembly method. Generally, the oil storage bottle 3 is not repeatedly disassembled and assembled from the oil storage bottle fixing position during use.

[0035] In addition, when in use, the panel 21 is placed toward the operator, and the panel 21 is tilted away from the oil storage bottle fixing position from top to bottom. On one side wall of the base 2, that is, beside the panel 21 and the oil storage bottle fixing position, a bracket 12 extending to the side is connected to form a three-purpose spray gun placement position. The oil storage bottle 3 is installed in the oil storage bottle fixing position and is in a fixed state; the three-purpose spray gun 1 is detachably installed in the three-purpose spray gun placement position.

[0036] At the same time, the top of the oil storage bottle 3 is provided with an oil filling port and an oil storage bottle cap 31 detachably connected to the oil filling port, wherein the connection between the oil storage bottle cap 31 and the oil filling port can be a bayonet connection, a threaded connection, a hook groove connection, etc., and the outer peripheral wall of the oil storage bottle cap 31 is provided with anti-slip grooves as shown in the figure. The bottom of the oil storage bottle 3 is provided with an air inlet and an oil outlet. An oil circuit 5 and an air circuit 6 are penetrated inside the machine base 2, the upstream of the air circuit 6 is used to connect to the air source, and the downstream of the air circuit 6 is respectively connected to the air inlet of the oil storage bottle 3 and the air inlet of the three-purpose spray gun 1, and the two ends of the oil circuit 5 are respectively connected to the oil outlet of the oil storage bottle 3 and the oil inlet of the three-purpose spray gun 1.

[0037] Therefore, when in use, the gas of the gas source forms a pneumatic force to enter the oil storage bottle 3, and the pneumatic transmission principle is used to drive the oil in the oil storage bottle 3 to enter the three-purpose spray gun 1. When there is no oil or insufficient oil in the oil storage bottle 3, it is only necessary to open the oil storage bottle cap 31 and fill the oil into it through the oil filling port without replacing the oil storage bottle 3. As a result, the cost is reduced, and the inconvenience of use caused by the need to always prepare to adapt the oil storage bottle 3 is avoided, and there is no need to interrupt the oil filling maintenance of the current dental handpiece. Based on this, a small-capacity oil storage bottle 3 can be selected relative to the prior art, so that the overall structure is smaller and more portable. At the same time, the oil is discharged from the bottom of the oil storage bottle 3, and gravity and gas pressure can be used at the same time to press the oil out of the oil storage bottle 3 more easily, and there will be no situation where the remaining oil remains in the oil storage bottle 3 and cannot be discharged.

[0038] Specifically in this embodiment, along the flow direction of the gas, the gas circuit 6 is mainly connected in series with a pressure reducing valve 7, a main gas switch 8 and a four-way valve 9, all of which are located in the hollow accommodation cavity of the base 2. Of course, the gas circuit 6 also has pipelines that realize the series connection of various devices. In order to clearly describe some key positions, only important pipelines are named and described in detail below.

[0039] Specifically, the gas circuit 6 includes an air inlet pipe 61, a first air outlet pipe 62 and a second air outlet pipe 63. The air inlet pipe 61 is connected between the air inlet of the four-way valve 9 and the main air switch 8, the first air outlet pipe 62 is connected between the first air outlet 91 of the four-way valve 9 and the air inlet of the oil storage bottle 3, and the second air outlet pipe 63 is connected between the second air outlet 92 of the four-way valve 9 and the air inlet of the three-purpose spray gun 1. A pressure gauge 10 connected to the third air outlet 93 of the four-way valve 9 is provided.

[0040] Thus, the four-way valve 9 is in a state of one inlet and three outlets. After the gas from the gas source enters the gas path 6, it enters the four-way valve 9 through the pressure reducing valve 7 and the total gas switch 8, enters the oil storage bottle 3 through the first gas outlet pipe 62, and enters the three-purpose spray gun 1 through the second gas outlet 92, and is monitored and measured by the pressure gauge 10. Among them, the function of the pressure reducing valve 7 is to control the pressure of the gas source when it enters the oil injection machine; the function of the total gas switch 8 is to allow or cut off the gas from the gas source to enter, and close the total gas switch 8 when it is not used or fails. The main body of the three-purpose spray gun 1 used in this embodiment is the existing technology, which has an operating component on it, and can switch between three different functions of oil spraying, jet and spray. The setting of the four-way valve 9 can not only lead the gas to the three-purpose spray gun 1, but also provide an interface to connect the current gas to the pressure gauge 10 to monitor the gas pressure intuitively. Different pressure values ​​can produce different sizes of effects of oil spraying, jet and spray. The pressure gauge 10 and the pressure reducing valve 7 can control the superposition of the effects and more accurately control the size of oil spraying, jet and spray of the three-purpose spray gun 1.

[0041] The oil circuit 5 in this embodiment includes an oil regulating valve 11 and oil delivery pipes on both sides of the oil regulating valve 11. The oil regulating valve 11 is also located in the hollow accommodation chamber of the machine base 2 and is used to adjust the amount of oil. When the amount required for lubrication is large enough to make the oil coming out of the dental handpiece head, the oil output needs to be reduced. When the oil coming out of the dental handpiece is no longer black, the oil is stopped, which can also save the amount of oil used to a certain extent. According to the required amount of oil, the oil regulating valve 11 controls the amount of oil output from the oil circuit 5.

[0042] For convenience and observation, the operating end of the total gas switch 8 extends to the outside of the panel 21, and is a lever. The upward and downward movements represent one of the states of opening and closing, respectively. The panel 21 is provided with an oil regulating valve regulating knob 212 linked to the oil regulating valve 11, and the panel 21 is provided with a pressure reducing valve regulating knob 211 linked to the pressure reducing valve 7, and the pressure gauge 10 is also provided on the panel 21. At the same time, the operating end of the total gas switch 8, the pressure reducing valve regulating knob 211, the pressure gauge 10 and the oil regulating valve 11 are arranged in a matrix of two rows and two columns, and the pressure gauge 10, the pressure reducing valve regulating knob 211, the oil regulating valve regulating knob 212 and the total gas switch 8 are arranged in a clockwise direction. Through the structural settings on the panel 21 and above, all functions can be concentrated, which is convenient for observation and use, and the oil regulating valve 11 and the pressure reducing valve 7 are controlled by the corresponding oil regulating valve regulating knob 212 and the pressure reducing valve regulating knob 211, which can be adjusted separately or linked to each other and controlled together, and the control effect is better.

[0043] As mentioned above, in order to facilitate the connection and improve the air tightness of the connection, the bottom of the oil storage bottle 3 is provided with an air inlet nozzle 32 and an oil outlet nozzle 33, the air inlet nozzle 32 extends into the hollow accommodation cavity inside the machine base 2 and is connected to the first air outlet pipe 62 of the air circuit 6, and the oil outlet nozzle 33 extends into the hollow accommodation cavity inside the machine base 2 and is connected to the oil delivery pipe of the oil circuit 5. Therefore, the air inlet nozzle 32 constitutes the air inlet of the oil storage bottle 3, and the oil outlet nozzle 33 constitutes the oil outlet of the oil storage bottle 3.

[0044] In this embodiment, the bracket 12 can be an integral part of the base 2, or it can be snap-connected to the main body of the base 2, or it can be adhered to the main body of the base 2; after use, the three-purpose spray gun 1 can be placed on the bracket 12, which is convenient to use and can be used at any time. The head of the three-purpose spray gun 1 will not come into contact with other objects to cause contamination, and it does not need to be dismantled and placed elsewhere after each use, which is time-consuming and laborious.

[0045] The base 2 is also provided with a pipe hole 13 through which the air supply line 6 and the oil line 5 pass. A protective coil is installed on the pipe hole 13 to facilitate the pipes included in the air line 6 and the oil line 5 to pass from the outside to the inside of the base 2 / pass from the inside of the base 2 to the outside, thereby preventing the base 2 from scratching the oil line 5 and the air line 6.

[0046] In addition, in this embodiment, the length of the base 2 is within the range of 260-270 mm, the width is within the range of 120-130 mm, the height is within the range of 135-145 mm, the material is plastic, and the main body of the base 2 (excluding the hanger 12) is formed by vacuum molding; wherein, the length direction of the base 2 is the direction from the panel 21 to the oil storage bottle 3. The diameter of the oil storage bottle 3 is within the range of 85-95 mm, the height is within the range of 95-105 mm, the capacity is within the range of 300-400 ml, and the material is stainless steel. As a result, the oiling machine of this embodiment is more compact and portable.

[0047] In addition, the nozzle of the three-purpose spray gun 1 is constructed as a detachably connected high-speed oil injection conversion head 1b and a low-speed oil injection joint 1a, and the low-speed oil injection joint 1a is connected to the three-purpose spray gun 1. For example, the connection between the low-speed oil injection joint 1a and the three-purpose spray gun 1 can be detachably connected by snap connection, threaded connection, or fixed connection such as bonding. The high-speed oil injection conversion head 1b is detachably connected to the low-speed oil injection joint 1a, and the connection method between the two can be snap connection, threaded connection, lock connection, etc. A sealing ring is also provided at the connection between the high-speed oil injection conversion head 1b and the low-speed oil injection joint 1a to improve the air tightness of the joint.

[0048] During use, when oiling a low-speed dental handpiece, a low-speed oiling connector 1a can be detachably connected to the high-speed oiling conversion head 1b; when oiling a high-speed dental handpiece, the low-speed oiling connector 1a can be removed, and the high-speed dental handpiece is directly connected to the high-speed oiling conversion head 1b. Therefore, the oiling machine of this embodiment can be connected to both the high-speed dental handpiece and the handpiece connector assembly 4 of the low-speed dental handpiece, thereby increasing the scope of application of the present invention.

[0049] In summary, the use process of the dental handpiece oiler of this embodiment is as follows:

[0050] Turn on the main gas switch 8 to make the gas circuit 6 conductive. The outermost end of the gas circuit 6 is connected to the gas source, and the gas enters the pressure reducing valve 7 through the gas circuit 6. The pressure reducing valve 7 can control the size of the gas entering. After passing through the pressure reducing valve 7, the gas reaches the main switch 8. After passing through the main gas switch 8, the gas enters the gas inlet of the four-way valve 9. The gas passes through the four-way valve 9 and is output from its first gas outlet 91 and second gas outlet 92 respectively, and continues to enter the gas inlet of the oil storage bottle 3 and the gas inlet of the three-purpose spray gun 1. At the same time, the pressure gauge 10 detects the gas pressure value in the four-way valve 9.

[0051] If the three-purpose spray gun 1 is adjusted to the jetting working state, all the gas is output to the second gas outlet 92 through the four-way valve 9, enters the second gas outlet pipe 63, continues to move forward, and then enters the gas inlet of the three-purpose spray gun 1, and exits from the nozzle of the three-purpose spray gun 1. The pressure reducing valve adjustment knob 211 on the panel 21 can control the specific gas pressure;

[0052] If the three-purpose spray gun 1 is adjusted to the oil spraying condition, at this time all the gas is output to the first air outlet 91 through the four-way valve 9, enters the first air outlet pipe 62, continues to move forward, and then reaches the air inlet of the oil storage bottle 3. By using the pneumatic transmission principle, the gas enters the oil storage bottle 3, drives the oil in the oil storage bottle 3 to enter the oil circuit 5, and the gas continues to fill the oil storage bottle 3, and there is constant power to drive the oil entering the oil circuit 5 to continue to move forward. When it moves forward to the oil regulating valve 11, the oil regulating valve regulating knob 212 on the panel 21 can control the specific amount of oil passing through the oil regulating valve 11. The oil coming out of the oil regulating valve 11 continues to move forward to the oil inlet of the three-purpose spray gun 1 and goes out from the nozzle of the three-purpose spray gun 1;

[0053] If the three-purpose spray gun 1 is adjusted to the spray working condition, the gas is divided into two paths through the four-way valve 9, one path of gas is output to the first gas outlet 91, and the other path of gas is output to the second gas outlet 92. The gas continues to move forward, and the jet working condition and the oil injection working condition occur at the same time, which will not be repeated here. The oil and gas are mixed in the nozzle of the three-purpose spray gun 1. Since the speed of the oil is slower than the speed of the gas, a speed difference is formed, and the gas atomizes the oil to form fine oil mist particles, thereby achieving a spray effect.

[0054] Wherein, the main gas switch 8 needs to be closed when opening the oil storage bottle 3. Because when the main gas switch 8 is opened, the oil storage bottle 3 is in a long-term gas supply state, and opening the oil storage bottle 3 is dangerous.

[0055] Embodiment 2:

[0056] Reference Figures 4 to 6 On the basis of Example 1, the dental handpiece oiler of this embodiment further includes a collecting device, which collects the waste oil discharged when the dental handpiece is oiled and maintained. Specifically, the collecting device of the dental handpiece oiler of this embodiment includes a collecting device body 14, a hole 16, an oil-absorbing cotton 15 and a handle 17, as described in detail below.

[0057] The collecting device body 14 is constructed as a retractable hollow quadrangular pyramid structure, which gradually shrinks inward from bottom to top. Each layer of the collecting device body 14 is a rectangular shell. The bottom surface of the bottom rectangular shell is closed, forming the bottom plate of the collecting device body 14, and the bottoms of the other layers of rectangular shells are provided with outward annular flanges; the top surface of the top rectangular shell is closed to form the top plate of the collecting device body 14, and the holes 16 are provided on the top plate, and the tops of the other layers of rectangular shells are provided with inward annular flanges.

[0058] When the collecting device body 14 is in a folded state, all the rectangular shells are nested together with the top surfaces flush; when the collecting device body 14 is in an unfolded state, in two adjacent layers of rectangular shells, the outward annular flange at the bottom of the upper rectangular shell and the inward annular flange at the bottom of the lower rectangular shell just abut against each other to prevent the rectangular shells from falling out.

[0059] The top plate of the collecting device body 14 is a plastic plate hinged on both sides, which can be opened and closed. Two semicircular holes 16 are left in the middle of the two side covers. When the dental handgun needs to be put in, the cover is opened; after the head of the dental handpiece is inserted, the cover is closed, and the hole 16 just catches the increasingly thick tail of the dental handpiece. In order to ensure that the discharged waste oil mist does not fly out of the collecting device, the top cover can be closed when the dental handpiece head is placed in the collecting device. A through hole 16 is set in the middle of the two side covers. When they are closed together, the rear of the dental handpiece is just caught to form a closed space. Corresponding handles 17 are set on the two side covers for easy opening and closing of the collecting device.

[0060] Furthermore, each layer of the rectangular shell of the collecting device body 14 is made of transparent material, which makes it easy to observe the internal situation. At the same time, the inside of the collecting device body 14 is a hydrophobic and oleophobic coating.

[0061] In addition, in order to collect the discharged waste oil, the last rectangular shell of the collection device body 14 is provided with oil-absorbing cotton 15, which fills the bottom of the collection device body 14 and is half the height of the bottom rectangular shell. When the collection device body 14 is folded up, the oil-absorbing cotton 15 can be pressed down and the oil-absorbing cotton 15 only absorbs oil but not water, so there is no need to worry about the oil-absorbing cotton 15 getting wet; when the collection device body 14 is opened, it can start to absorb oil, and the oil-absorbing cotton 15 can absorb oil that is dozens of times its own weight. Therefore, it is not necessary to replace the oil-absorbing cotton 15 more frequently during work. After use, the collection device body 14 needs to be cleaned and the oil-absorbing cotton 15 replaced.

[0062] A drawer is provided at the bottom of the base 2, and the collecting device can be placed in the drawer when in a folded state. In this way, the oiling machine can be carried and used in a portable manner. When in use, the drawer can be opened directly to take out the collecting device. The size of the collecting device is adapted to the drawer space, and the collecting device can be placed in the drawer and fixed without relative movement.

[0063] Embodiment 3:

[0064] Reference Figure 7 This embodiment can be based on the first or second embodiment, and can add a timed and quantitative oil discharge function to maintain dental handpieces with different lubrication requirements. Specifically, this embodiment also includes a time adjustment knob, as described in detail below.

[0065] For the oiling machine in the original embodiment 1 or embodiment 2, the oil regulating valve regulating knob 212 is adjusted, and specifically set to the first gear, the second gear and the third gear. The first gear is the oil regulating valve 11 opened 1 / 4 state. At this time, the oil output is small, which is for dental mobile phones that require less lubricating oil or have squeezed out the black lubricating oil and only need a small amount of lubricating oil; the second gear is the oil regulating valve 11 opened 1 / 2 state. At this time, it is a normal oil output. For conventional dental mobile phones and dental mobile phones without additional needs, normal maintenance and oiling are performed; the third gear is the oil regulating valve 11 fully opened state. For some dental mobile phones that require a large amount of lubricating oil, oiling and lubrication are performed. At this time, the diameter of the oil pipe is constant. When the position of the pressure reducing valve 7 is constant, the oil output speed is constant.

[0066] In order to better control the amount of oil output, a switch is set on the air pipe between the pressure reducing valve 7 and the main gas switch 8. A time adjustment knob is correspondingly set on the machine base 1. The time adjustment knob can be set between 0.5-5s. If the maximum time exceeds 5s, it is in the normally open state with no time limit. When the time adjustment knob is not selected to adjust, when the main gas switch 8 is turned on, it is still in the closed state, and neither oil nor gas is output. Adjust the time adjustment knob and select the required time. At this time, oil injection starts. When the time reaches the preset time, the switch is disconnected and the oil injection stops. At this time, the oil output is the required oil output, thereby achieving the purpose of timed and quantitative oil output.
