Description

Technical Field

[0001] The utility model relates to dental equipment, in particular to a comprehensive veterinary dental therapeutic instrument. Background Art

[0002] In modern life, the proportion of families keeping pets is increasing year by year, and the corresponding pet market segments are becoming more and more diverse.

[0003] As people pay more attention to animal welfare and have a stronger awareness of oral health, the animal dental equipment market is growing faster. Therefore, more and more pet hospital dental clinics will have the demand to introduce specialized dental treatment.

[0004] There are already some dental treatment equipment for pets on the market, which are generally adapted from dental equipment used by humans for pets, such as dental handpieces, X-ray machines, etc. At present, such equipment has separate functions and needs to be purchased separately, which is troublesome, costly, and occupies a large area. Therefore, there is an urgent need for a pet-specific all-in-one machine with comprehensive dental treatment functions.

[0005] The integrated dental treatment machine used for dental patients can be used as a reference for such products. However, unlike human medical equipment, pet hospitals are often not large in scale. Whether it is the floor area, the volume and number of equipment, or the size of the treatment area, they are much smaller than the scale of a real hospital, which requires much higher volume and space for the equipment. One situation where the integrated dental treatment machine for humans cannot be applied is that the dentist's handpiece used for direct cleaning and surgery on teeth needs to be connected to compressed gas to work. The equipment that provides compressed gas is an air compressor, but traditional air compressors are very noisy when running, which will greatly affect the treatment process. Therefore, air compressors are generally placed separately in another room outside the treatment room, so that no noise can be heard in the treatment room when it is working. This is a huge challenge for pet hospitals, because the space is usually limited and such a separate room cannot be provided. In addition, pets are more sensitive to sound. If they feel the noise, they may not be able to cooperate with the treatment at all. Summary of the invention

[0006] The utility model patent provides the society with a veterinary dental comprehensive treatment instrument with high integration, small footprint and good mute effect.

[0007] In order to solve the above problems, the utility model provides a veterinary dental comprehensive treatment instrument, comprising:

[0016] Furthermore, the air compression system also includes a pressure switch, a pressure reducing valve and a safety valve; the pressure switch is connected to the gas tank to detect the pressure in the gas tank, and when the pressure in the gas tank is less than a low setting value, the compressor power is turned on to make the compressor work; the pressure reducing valve is connected to the gas tank to adjust the pressure in the gas tank to a preset value and then output it for use by the therapeutic device; the safety valve is connected to the gas tank and discharges excess air when the pressure in the gas tank reaches a high setting value.

[0017] Further, the compressor is a single-cylinder air compressor, and the compressor is a sealed shell defined by an air intake port and an air exhaust port.

[0018] Furthermore, the air compression system also includes a one-way valve. The compressor sucks in air from the air inlet, compresses it and discharges it through the air outlet. The compressed air enters the air storage tank through the one-way valve and is pressure-adjusted before being output to the treatment device.

[0020] Furthermore, a gap between an outer side surface of the silicone plug parallel to its moving direction and an inner surface of the valve cap facing the outer side surface of the silicone plug is between 0.1 and 0.4 mm.

[0021] Furthermore, the treatment equipment includes at least one of a display screen, an X-ray machine, and an oral light, and the circuit system is connected to the display screen or the X-ray machine or the oral light circuit; the treatment equipment also includes at least one of a medical mobile phone console and an anesthesia machine, and the air compression system is connected to the medical mobile phone console or the anesthesia machine air circuit.

[0032] The following will be combined with the drawings in the embodiments to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model protects a veterinary dental comprehensive treatment instrument. Different from the prior art, the all-in-one machine of this solution is fully functional, small in size, and super quiet, which is very suitable for the environment of a pet hospital.

[0034] Specifically, Figure 1 As shown, the veterinary dental comprehensive treatment instrument of the present invention includes a base, a mounting frame, and treatment equipment installed on the mounting frame, such as an X-ray machine 6, a medical handpiece console 7, a display screen 8, a dental lamp 9, etc. Although in this embodiment, these four treatment equipment are all located on the mounting frame, it is obvious that not all equipment must be present or connected when not needed. For example, only the display screen 8, the dental handpiece console 7, etc. are allowed, as long as the structure of the mounting frame allows the installation of two or more (i.e., multiple) treatment equipment.

[0035] Among them, the base is basically a cube, with a shell 1 of a corresponding shape, and the shell is assembled from six panels: upper, lower, left, right, front and rear. The mounting frame includes a column 2 arranged in the vertical direction, and the column 2 vertically penetrates into the shell from top to bottom and is connected and fixed at the bottom of the shell. Of course, the column 2 may also have only a part installed on the upper panel of the shell 1. And a plurality of mechanical arms 3 are mounted on the column, one end of the mechanical arm 3 is directly or indirectly connected to the column, and the other end is used to connect and install the therapeutic device. The mechanical arm has multiple joints. For example, a mechanical arm composed of two arms has at least three joints at the two ends and the middle connection, which can provide multiple degrees of freedom of displacement, so that the therapeutic device can flexibly move in all directions such as up and down, left and right, front and back, and rotation.

[0036] In order to increase the arm span, for example, the X-ray machine 6, the dental handpiece operating table 7, etc. need to be close to the pet and adapt to the various body shapes of the pet for detection and operation, so a larger activity space is required. Therefore, a certain length of mounting rod is extended horizontally at different positions on the column, such as Figure 1 As shown, one end of the mechanical arm of the X-ray machine 6 is connected to the end of a mounting rod, and one end of the mechanical arm of the dental handpiece console 7 is connected to the end of another mounting rod, so that the range of motion of the X-ray machine 6 and the dental handpiece console 7 can be expanded and the versatility can be improved. Of course, if the mechanical arm is long enough, the mounting rod may not be required. Or some treatment equipment may not be connected through the mechanical arm or the mounting rod, but can be directly connected to the column. These situations are all possible and fall within the scope of protection of this patent.

[0037] like Figure 2 , Figure 3 As shown, the veterinary dental comprehensive treatment instrument of the present invention also includes a circuit system 4 and an air compression system 5. The circuit system 4 is used to be electrically connected to treatment equipment such as a display screen 8, an X-ray machine 6, a dental lamp 9, etc. to provide electrical energy or electrical control. The air compression system 5 is used to be connected to treatment equipment such as a medical handpiece operating table 7, an anesthesia machine, etc. to provide compressed air to drive the equipment to operate.

[0038] The circuit system 4 and the air compression system 5 are both located in the housing 1 of the base. Figure 2 , Figure 3 As shown, a horizontal partition is installed in the housing 1, dividing the internal space of the housing 1 into two upper and lower cavities. The circuit system 4 contains at least components such as a circuit board, which is installed in the upper cavity of the housing 1, while the air compression system 5 is located in the lower cavity, i.e., the bottom, of the housing 1. The circuit board of the circuit system is generally connected to the equipment that needs to be connected, communicated or controlled by electricity through wires and other lines. These lines are contained in the housing, which makes the entire all-in-one machine simpler. The air compression system is relatively heavy, and placing it at the bottom of the housing 1 can have a counterweight effect to a certain extent.

[0039] In this patent, the air compression system 5 is placed in the shell 1 of the base, rather than placed separately in another isolated room, which is the first difference between this pet dental treatment machine and the human dental treatment machine. The air compression system 5 is installed in the shell, which can greatly reduce the site burden of the pet hospital and also reduce the operation and maintenance costs such as remote installation.

[0040] However, if the air compression system is built-in, it is necessary to eliminate the noise so that the pet dental treatment machine can be used normally. The air compression system used in this patent and its working principle will be described in detail below.

[0041] like Figure 4 , Figure 5 As shown, the air compression system 5 of the present patent includes a compressor 57, an air storage tank 58, and components that cooperate with the two include a pressure reducing valve 51, a safety valve 52, a pressure switch 53, a solenoid valve 54, a drain port 55, a one-way valve 56, a pressure gauge 59, etc.

[0042] Specifically, the pressure switch 53 is connected to the pressure reducing valve 51, and is also electrically connected to the compressor 57 and the gas storage tank 58. When the pressure switch 53 detects that the air pressure value in the gas storage tank 58 is less than a low preset value, such as 0.5 MPa, it indicates underpressure. At this time, the pressure switch 53 will automatically connect the power supply of the compressor 57 to make it work. The compressor 57 will inhale air from the air inlet. Before inhalation, the air can pass through an air filter to prevent dust and other impurities from entering the compressor. The compressor 57 compresses the inhaled air and discharges it from the exhaust port. The discharged compressed air flows through a one-way valve 56 through an air duct and enters the gas storage tank 58. The one-way valve 56 allows air to flow only in one direction, that is, from the compressor 57 to the gas storage tank 58. The compressed gas in the gas storage tank 58 is adjusted to a preset value, such as a pressure value set by the user, by the pressure reducing valve 51 and then output for use by therapeutic equipment such as mobile phones. The pressure reducing valve 51 is generally equipped with a pressure gauge 59, so that the user can know the pressure in the gas storage tank at a glance.

[0043] When the pressure switch 53 detects that the pressure value in the gas storage tank 58 is greater than a high preset value, such as 0.8 MPa, the power supply will be disconnected, and the safety valve 52 will open to discharge the excess gas so that the pressure in the gas storage tank 58 will not be higher than the high preset value. At the same time, the solenoid valve 54 will also work to discharge the excess gas in the air duct to prevent the high-pressure gas in the air duct from flowing back and causing the compressor 57 to reverse and be damaged.

[0044] In addition, a drain port 55 is provided at the bottom of the gas storage tank 58. This is because after the air is compressed, the spacing between molecules becomes smaller, and the movement of molecules generates heat. Therefore, when the compressor stops working, the heat will dissipate, forming a condensation phenomenon, and the water molecules in the gas storage tank will condense into water. If the water is left in the gas storage tank, it will corrode the gas storage tank, so the condensed water in the gas storage tank 58 needs to be discharged from the drain port 55 regularly.

[0045] As in this embodiment, the volume of the compressor is smaller than that of the air storage tank, so the compressor and other components of the air compression system 5 are installed on the air storage tank, which can be arranged compactly, thereby reducing the volume.

[0046] Such an air compression system 5 is small in size and compact in structure, and can be easily placed in the housing 1 to achieve the integration of the entire set of dental treatment equipment.

[0047] There are many choices of medical dental treatment equipment on the market. Because the site is not limited, air compression systems with large volume and sufficient air storage capacity are generally used without considering the volume. In addition, the idea of ​​putting the air compression system and treatment equipment together as a whole is contrary to their common sense, because air compression has always been closely related to noise.

[0048] In order to solve the noise problem and achieve a silent effect, the inventor of this patent has repeatedly screened and considered, and finally selected a single-cylinder air compressor as the compressor type of the air compression system. There are many types of compressors on the market, such as scroll compressors, centrifugal compressors, piston compressors, rotary vane compressors, etc. Some dental equipment in hospitals will use a double-cylinder piston air compressor, but this type of compressor has a relatively large double-cylinder volume, a large gas compression volume, and a large power and heat generation. Therefore, it uses an open heat dissipation and ventilation channel, so the noise is very loud and cannot be applied to this patent.

[0049] In this solution, the inventor has selected a single-cylinder piston air compressor after screening, which can realize air compression in a single cylinder. Accordingly, the compressor casing is provided with an air intake port and an air exhaust port. Air enters from the air intake port, enters the cylinder body and is compressed, and then is discharged from the air exhaust port. When the air intake port and the air exhaust port are connected through the air duct, the air intake port, the air exhaust port and the compressor casing form a sealed shell. Since a closed compressor is used, there is no need to open a ventilation and heat dissipation channel, so there is no wind noise. At the same time, the sealed shell can reduce the internal noise and conduct it out, further reducing the noise. Unlike other compressors used in existing human dental treatment tables, it does not require multiple strokes of air intake and air exhaust cycles, which results in particularly loud noise.

[0050] Furthermore, during the actual product development process, the inventor of the present invention further optimized the above-mentioned air compression system in order to achieve a better mute effect.

[0051] like Figure 6 As shown, a one-way valve 56 is connected between the exhaust port of the compressor 57 and the air inlet of the air storage tank 58. The function of the one-way valve 56 is to deliver the compressed air discharged from the exhaust port of the compressor 57 to the air storage tank 58 in one direction.

[0052] Specifically, the one-way valve includes a valve body 561, a silicone plug 562, a spring 563, and a valve cap 564. The valve body 561 is open at both ends, and a cavity connected to the opening is provided inside. The silicone plug 562 is inserted into the cavity of the valve body 561 from one end opening, and the valve cap 564 is fixedly connected to the open end of the valve body 562 through the external thread at the end, so that the silicone plug 562 is enclosed in the cavity enclosed by the valve cap 564 and the valve body 561, and the silicone plug 562 can reciprocate axially in the cavity. The spring 563 is installed in the cavity enclosed by the valve cap 564 and the valve body 561, and one end of the spring abuts against the end surface of the silicone plug 562, and the other end abuts against the inner end surface of the valve cap 564, providing elastic restoring force to the silicone plug 562 at one end.

[0053] like Figure 6 As shown, the left end face of the valve body 561 is provided with an air inlet hole, which is connected to the air duct to receive the compressed gas discharged from the compressor 57; the lower end of the valve body 561 is also provided with an air outlet hole for connecting to the air storage tank 58, and the silicone plug 562 is provided on the connecting channel between the air inlet hole and the air outlet hole.

[0054] The silicone plug 562 is located in the cavity of the valve body 561 and is moved axially in the cavity by the thrust of the compressed air, that is, the left and right movement shown in the figure. The communication channel is located at the position where the movement trajectory of the silicone plug 562 passes. When the pressure of the compressed air is not large enough to push the silicone plug 562 to resist the spring elastic force to deform, the silicone plug 562 will block the communication channel between the air inlet and the air outlet, so that the insufficiently compressed air will not enter the air storage tank 58. When the compressed air continues to be compressed, the pressure increases until it pushes the silicone plug to move to the right and forces the spring 563 to be compressed, until the compressed air continues to push the silicone plug 562 to leave the position of blocking the communication channel and expose the exhaust port. At this time, the compressed air will quickly flow out from the exhaust port and the pressure will decrease. When it is reduced to a certain extent and its pressure is not enough to push the silicone plug 562 to resist the spring elastic force, the spring elastic force does work, pushing the silicone plug to move left and reset to block the exhaust port, so as to enter the next cycle.

[0055] During this process, the setting of process parameters is crucial to the quietness of the air compression system. It is also a very important challenge to ensure that the air compression system can enter the base and be placed in the treatment room without affecting the treatment process.

[0056] After repeated experiments and corrections, the inventors have found that the noise problem of the air compression system is located on the one-way valve 56. When the gap between the outer side of the silicone plug 562 parallel to its moving direction and the inner surface of the valve cap 563 facing the outer side of the silicone plug, that is, Figure 6 When the distance H shown in the figure is between 0.1” and 0.4mm, the howling in the check valve will be significantly reduced, thereby further improving the quiet effect.

[0057] In order to verify the quiet effect brought about by the optimization of the internal structural parameters of the one-way valve in the design of this scheme, the following comparative test is carried out in this scheme.

[0058] The specific test conditions are:

[0059] Use two 15L gas tanks of the same size, and install two single-cylinder piston air compressors of the same specifications on the gas tanks respectively. The pressure switch, safety valve, pressure reducing valve, solenoid valve, etc. are all made of materials of the same specifications, and use the same size of one-way valves (the one-way valve body is the same, only the size of the silicone plug is different), and connect them with the same specifications of the air intake pipe and other accessories.

[0060] Samples 1# and 2# are exactly the same. The valve core of their one-way valves uses a silicone plug with a diameter of 15mm and a valve cap with an inner diameter of 15.5mm. The gap H between the outer diameter of the silicone plug and the inner diameter of the valve cap is 0.25mm.

[0061] The parts structure of samples 3# and 4# are exactly the same, and the difference from samples 1# and 2# is that the diameter of the silicone plug of the one-way valve is 13.5mm, the inner diameter of the valve cap is still 15.5MM, and the single-side clearance H between the two is 1mm.

[0062] The four samples were tested using the same noise meter in the same indoor and outdoor environment, 1 meter away from the machine.

[0063] The specific test method is: connect the prototypes to the power supply, adjust the preset pressure value to 0.8MPa, and start measuring. Place the noise meter at 5 positions on the front, back, left, right, and top of the machine, test and record the maximum noise during the process of the compressor filling the air tank. Test each position twice and take the larger value.

[0064] The test results are shown in the following table. The average values ​​of the five data points under the same conditions are calculated, and it can be seen that the noise of samples 1# and 2# is 49.6 decibels and 50.3 decibels on average, while the noise of samples 3# and 4# is 54.7 decibels and 54.9 decibels on average. It can be seen that the one-way valve with a valve core clearance H of 0.25mm can effectively reduce the noise by nearly 4 to 5dB, and the silencing effect is very obvious. The inventor finally verified that multiple data points with valve core clearance H between 0.1 and 0.4mm can effectively reduce howling and achieve a silencing effect.

[0065]

[0066] In summary, the beneficial effects of the integrated dental treatment machine provided by the embodiment of the utility model are as follows: by integrating the air compression system into the integrated machine, it is possible to avoid building a separate room to place the air compression system, thereby saving space and cost; further, by selecting a suitable compressor to make the entire air compression system silent, and optimizing the one-way valve to enhance the silent effect, the integrated dental treatment machine of the utility model not only has high functional integration, small size, low cost, but also has excellent silent performance.

[0067] Obviously, the above embodiments of the present invention are merely examples used to clearly illustrate the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description, and it is not necessary and impossible to list all the implementation methods here.
