Description

Technical Field

[0001] The present invention relates to the technical field of dental cleaning equipment, and particularly to a dental cleaning sandblasting handle and a dental cleaning device. Background Art

[0002] When users do not pay enough attention to oral hygiene, dental plaque and pigments on teeth will increase day by day. Along with the deposition of minerals such as calcium contained in food residues, dental calculus is likely to form on the tooth surface. Dental calculus is the most important factor leading to periodontal disease and premature tooth loss. Clinically, it is mainly manifested as gingival bleeding and bad breath. If not taken seriously, it will further develop into symptoms such as gingival recession and tooth loosening.

[0003] In response to the above problems, sandblasting dental cleaning is an effective way to solve the above problems. Sandblasting dental cleaning uses air polishing technology. When compressed gas passes through a pipeline, it entrains abrasive powder and sprays the abrasive powder onto the tooth surface, mixing with the cleaning liquid sprayed together. The biological sea salt contained in the abrasive powder can sterilize and reduce inflammation, polish the tooth surface and dental floss. After polishing, dental plaque and pigments are not easily attached to the tooth surface, and dental plaque and pigments can be effectively removed, which plays a very important role in tooth care.

[0004] The sandblasting handles in the prior art cannot effectively control the sand output. As time goes by, when the remaining sand amount is less, the sand output shows a continuous increasing trend. The rapid ejection of the remaining abrasive powder is not conducive to reminding doctors of the dental cleaning treatment for patients.

[0005] The above content is only used to assist in understanding the technical solution of the present application, and does not represent an admission that the above content is prior art. Summary of the Invention

[0006] The main object of the present invention is to provide a dental cleaning sandblasting handle, aiming to be able to replenish abrasive powder in time, control the ejection amount of abrasive powder, thereby improving work efficiency and enhancing the dental cleaning effect.

[0007] To achieve the above object, the dental cleaning sandblasting handle proposed by the present invention includes a handle body. A receiving cavity is provided inside the handle body. The receiving cavity is communicated with an air inlet and an air outlet. A partition member is provided in the receiving cavity to divide the receiving cavity into an air passing chamber and a sand receiving chamber. A mixing channel is formed above the air passing chamber and the sand receiving chamber. The partition member is further provided with a connecting channel communicating the air passing chamber and the sand receiving chamber. The air inlet is communicated with the air passing chamber, and the air outlet is communicated with the mixing channel.

[0008] In an embodiment of the present invention, the height value of the end of the connecting channel communicating with the air passing chamber is greater than the height value of the end of the connecting channel communicating with the sand receiving chamber.

[0009] In an embodiment of the present invention, the connecting channel is arranged to extend obliquely.

[0010] Alternatively, the connecting channel is arranged in a spiral shape;

[0011] Alternatively, the connecting channel is arranged in an arc curve shape.

[0012] In an embodiment of the present invention, the number of the connecting channels is multiple, and the multiple connecting channels are arranged at intervals along the height direction of the partition member.

[0013] In an embodiment of the present invention, the opening area of one end of the connecting channel communicating with the air passing chamber is larger than the opening area of one end of the connecting channel communicating with the sandblasting chamber.

[0014] In an embodiment of the present invention, the connecting channel is located in the middle of the height direction of the partition member.

[0015] In an embodiment of the present invention, the dental cleaning sandblasting handle further includes an air inlet pipe and an outlet pipe connected to the handle body, the air inlet pipe communicates with the air inlet, the outlet pipe communicates with the air outlet, and both the air inlet pipe and the outlet pipe are arranged to extend vertically.

[0016] In an embodiment of the present invention, a dust-proof net is further provided at the air inlet.

[0017] The present invention also provides a dental cleaning device, including an air compressor and a dental cleaning sandblasting handle. The air compressor communicates with the air inlet. The dental cleaning sandblasting handle includes a handle body, and a receiving cavity is provided in the handle body. The receiving cavity communicates with an air inlet and an air outlet. A partition member is provided in the receiving cavity to divide the receiving cavity into an air passing chamber and a sand receiving chamber. A mixing channel is formed above the air passing chamber and the sand receiving chamber. The partition member is further provided with a connecting channel communicating the air passing chamber and the sand receiving chamber. The air inlet communicates with the air passing chamber, and the air outlet communicates with the mixing channel.

[0018] In an embodiment of the present invention, the dental cleaning device further includes a water outlet structure, and the water outlet structure includes a water outlet pipe. The outlet end of the water outlet pipe is used to be adjacently arranged with the outlet end of the outlet pipe of the dental cleaning sandblasting handle.

[0019] In the technical solution of the present invention, abrasive is provided in the abrasive storage chamber of the accommodation cavity. During use, external gas enters the air passage chamber through the air inlet and flows into the mixing channel via the air passage chamber. The abrasive storage chamber is communicated with the mixing channel. The gas flowing through the mixing channel generates an air pressure difference, causing the abrasive in the abrasive storage chamber to be carried into the mixing channel by the air pressure difference, and then ejected through the air outlet to perform dental cleaning treatment on the patient. When the amount of abrasive is sufficient, the connection channel is blocked by the abrasive, and the gas can only pass through the mixing channel, thus ensuring the sufficient supply of abrasive. When the abrasive is used to the position below the connection channel, after the gas passes through the mixing channel, the branch air flow entering the abrasive storage chamber will directly circulate out of the abrasive storage chamber through the air passage channel without generating an air pressure difference to carry the abrasive, so that no abrasive will be ejected at the air outlet. At this time, the doctor will notice and replenish the abrasive in time. Thus, it can be realized that the ejection amount of the abrasive is always relatively constant, further improving the working efficiency and enhancing the dental cleaning effect.

[0031] The present invention provides a dental cleaning and sandblasting handle 100.

[0032] Referring to Figure 1 and Figure 2 , in an embodiment of the present invention, the dental cleaning and sandblasting handle 100 includes a handle body 10. A receiving cavity (not labeled) is provided inside the handle body 10. The receiving cavity communicates with an air inlet 10a and an air outlet 10b. A partition member 11 is provided inside the receiving cavity to divide the receiving cavity into an air passage chamber 111 and a sand receiving chamber 113. A mixing channel 115 is formed above the air passage chamber 111 and the sand receiving chamber 113. The partition member 11 is further provided with a connecting channel 117 that communicates the air passage chamber 111 and the sand receiving chamber 113. The air inlet 10a communicates with the air passage chamber 111, and the air outlet 10b communicates with the mixing channel 115.

[0033] The handle body 10 can be made of plastic, rubber, or metal, and its shape can be set as needed. The chamber volume of the sand-containing chamber 113 can be set to be larger than the volume of the air-passing chamber 111, thereby increasing the powder storage capacity. The partition member 11 can be a baffle, and this baffle can be a detachable structure with the handle body 10 or an integral structure. When set as a detachable structure, the position of the baffle can be adjusted, thereby adjusting the relative height of the connection channel 117, and further controlling the amount of powder discharged.

[0034] In the technical solution of the present invention, sand is provided in the sand-containing chamber 113 of the accommodating cavity. During use, external gas enters the air-passing chamber 111 through the air inlet 10a and flows into the mixing channel 115 via the air-passing chamber 111. The sand-containing chamber 113 is communicated with the mixing channel 115. The gas flowing through the mixing channel 115 generates an air pressure difference, so that the sand 30 in the sand-containing chamber 113 is carried by the air pressure difference into the mixing channel 115, and then is ejected through the air outlet 10b for dental cleaning treatment of the patient. When the amount of sand 30 is sufficient (specific reference Figure 1 ), the connection channel 117 is blocked by the sand 30, and the gas can only pass through the mixing channel 115, thereby ensuring the sufficient supply of the sand 30. When the sand is used to be below the connection channel 117 (specific reference Figure 2 ), after the gas passes through the mixing channel 115, the branch air flow entering the sand-containing chamber 113 will directly circulate out of the sand-containing chamber 113 through the air-passing channel without generating an air pressure difference to carry the sand 30, so that no sand 30 will be ejected at the air outlet 10b. At this time, the doctor will notice and replenish the sand in time. Thus, it can be realized that the ejection amount of the sand is always relatively constant, further improving the working efficiency and enhancing the dental cleaning effect.

[0035] Further referring to Figure 1 and Figure 2 , in an embodiment of the present invention, the height value of the end of the connection channel 117 communicating with the air-passing chamber 111 is greater than the height value of the end of the connection channel 117 communicating with the sand-containing chamber 113.

[0036] Through the above setting, it is possible to prevent the sand from flowing back to the air inlet 10a.

[0037] Furthermore, the connection channel 117 is arranged to extend obliquely;

[0038] Or, the connection channel 117 is arranged in a spiral shape;

[0039] Or, the connection channel 117 is arranged in an arc curve shape.

[0040] The above-mentioned shape settings are all for further preventing the backflow of abrasive materials. It can be understood that other shapes can also be set, such as a polyline shape composed of multiple line segments, which is also within the protection scope of this application.

[0041] Furthermore, the number of the connecting channels 117 is multiple, and the multiple connecting channels 117 are arranged at intervals along the height direction of the partition member 11.

[0042] Through the arrangement of the multiple connecting channels 117, the effect of air flow control can be enhanced, and the situation that the overall device cannot regulate the air flow due to an accidental blockage of one connecting channel 117 can be prevented.

[0043] Furthermore, the opening area of one end of the connecting channel 117 communicating with the air passing chamber 111 is larger than the opening area of one end of the connecting channel 117 communicating with the sandblasting chamber.

[0044] With such a setting, the probability of the abrasive material 30 entering the air passing chamber 111 from the connecting channel 117 can be reduced. A filter screen can also be provided at the connecting channel 117 to further prevent the abrasive material 30 from entering the air passing chamber 111.

[0045] In an embodiment of the present invention, the connecting channel 117 is located in the middle of the height direction of the partition member 11.

[0046] With such a setting in the middle, the usage amount of the abrasive material 30 in the sand storage chamber 113 can be about half, which is convenient for controlling the volume of the abrasive material and also convenient for replenishing the abrasive material 30.

[0047] With reference to Figure 1 , in an embodiment of the present invention, the dental cleaning sandblasting handle 100 further includes an air inlet pipe 13 and an outlet pipe 15 connected to the handle body 10. The air inlet pipe 13 is communicated with the air inlet 10a, the outlet pipe 15 is communicated with the air outlet 10b, and both the air inlet pipe 13 and the outlet pipe 15 are vertically extended.

[0048] Through the arrangement of the air inlet pipe 13 and the outlet pipe 15, the connection between the dental cleaning sandblasting handle 100 and other air paths can be facilitated, such as the connection with an air compressor. At the same time, the vertical extension of both of them is also convenient for the air path setting of the dental cleaning sandblasting handle 100, saving the installation space.

[0049] Furthermore, a dust-proof net (not shown) is also provided at the air inlet 10a. By providing the dust-proof net, the backflow of the abrasive material 30 into the air compressor can be prevented, and the air compressor can be prevented from being damaged.

[0050] The present invention further provides a tooth cleaning device (not shown), which includes an air compressor (not shown) and a tooth cleaning and sandblasting handle 100. The air compressor is communicated with the air inlet 10a. For the specific structure of the tooth cleaning and sandblasting handle 100, reference may be made to the above embodiments. Since this tooth cleaning device adopts all the technical solutions of the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0051] In an embodiment of the present invention, the tooth cleaning device further includes a water outlet structure (not shown). The water outlet structure includes a water outlet pipe, and the outlet end of the water outlet pipe is arranged adjacent to the outlet end of the outlet pipe 15 of the tooth cleaning and sandblasting handle 100.

[0052] The effect of tooth cleaning is achieved by mixing the water outlet pipe of the water outlet structure with the abrasive 30 of the outlet pipe 15 of the tooth cleaning and sandblasting handle 100. The cleaning liquid is stored in the water outlet structure, which can reduce bacteria in the oral cavity and take away the dental calculus after cleaning.

[0053] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the description and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
