Technical Field
[0001] This utility model relates to the field of dental medical device technology, and in particular to a sand powder outlet structure and a sandblasting sand powder storage bottle. Background Technology
[0002] Currently, air polishing is the mainstream method for cleaning teeth in dentistry. An air polishing machine sprays abrasive powder onto the tooth surface to clean it. The powder container of the air polishing machine stores the powder for later use. When the powder in the container is low, powder from the storage bottle can be poured into the container to replenish it.
[0003] In practical applications, the cap of the abrasive powder storage bottle has a small hole to balance the air pressure inside and outside the bottle, allowing the abrasive powder in the storage bottle to be poured into the abrasive powder container. However, during the pouring process, the abrasive powder easily clogs the small hole on the cap, causing a pressure difference between the inside and outside of the bottle. This prevents the abrasive powder from flowing smoothly out of the storage bottle, affecting the efficiency of replenishing abrasive powder for the abrasive blasting machine. Therefore, improving the smoothness of abrasive powder pouring from the storage bottle has become an urgent problem to be solved. Utility Model Content

The air pressure balance part of the sand guide tube has a target flow port at the end close to the bottle cap body.
[0008] The air pressure balance port and the target flow port are connected. When the target sand powder in the sand powder container covers the air pressure balance port, the target sand powder in the sand powder container enters the sand guide pipe body through the air pressure balance port and the target flow port, and is then discharged through the sand outlet. When the target sand powder in the sand powder container does not cover the air pressure balance port, the target sand powder in the sand powder container enters the sand guide pipe body through the target flow port, and is then discharged through the sand outlet.
[0009] As an optional implementation, in an embodiment of the first aspect of this utility model, the target flow port includes a first flow port and a second flow port, wherein the first flow port and the second flow port are disposed opposite to each other on the pressure balance section of the sand guide tube body near one end of the bottle cap body.
[0010] As an optional implementation, in an embodiment of the first aspect of this utility model, the air pressure balance port is disposed at the end of the air pressure balance part of the sand guide tube body away from the bottle cap body with a preset first tilt direction and a preset first tilt angle.
[0011] As an optional implementation, in an embodiment of the first aspect of this utility model, the sand outlet is disposed at the end of the sand outlet of the sand guide tube body away from the bottle cap body with a preset second inclination direction and a preset second inclination angle.
[0012] As an optional implementation, in an embodiment of the first aspect of this utility model, the length of the air pressure balance section of the sand guide tube is the same as the depth of the sand powder container.
[0013] As an optional implementation, in an embodiment of the first aspect of this utility model, a connecting groove is provided on the connecting side of the bottle cap body, the diameter of the connecting groove is larger than the diameter of the bottle mouth of the sand powder container, and the bottle cap body is fitted onto the bottle mouth of the sand powder container through the connecting groove.
[0014] As an optional implementation, in an embodiment of the first aspect of the present invention, the bottle cap body has a first threaded connection portion, the first threaded connection portion being spirally shaped and disposed on the inner wall of the connecting groove along the axial direction of the bottle cap body, and the bottle cap body being threadedly connected to the bottle mouth of the sand powder container through the first threaded connection portion.
[0015] As an optional implementation, in an embodiment of the first aspect of this utility model, a connecting groove is provided on the connecting side of the bottle cap body, and the bottle cap body has a first threaded connecting part. The first threaded connecting part is spirally shaped and disposed on the inner wall of the connecting groove along the axial direction of the bottle cap body. The bottle cap body is threadedly connected to the bottle mouth of the sand powder container through the first threaded connecting part.
[0016] Secondly, this utility model discloses a sandblasting powder storage bottle, which includes:
[0017] The sand powder outlet structure as described in the first aspect of this utility model;
[0018] A sand powder container, wherein the mouth of the sand powder container is connected to the connecting side of the cap body.
[0019] As an optional implementation, in an embodiment of the second aspect of the present invention, the mouth of the sand powder container has a second threaded connection portion, the second threaded connection portion being spirally shaped and disposed on the outer wall of the mouth of the sand powder container along the axial direction of the mouth of the sand powder container, and the sand powder container being threadedly connected to the cap body through the second threaded connection portion.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] The sand powder outlet structure provided by this utility model transports the target sand powder in the sand powder container to the sand outlet through the target flow port. At the same time, through the air pressure balance port, it can transport the target sand powder in the sand powder container to the sand outlet when the target sand powder in the sand powder container covers the air pressure balance port, and can balance the air pressure in the sand powder container when the target sand powder in the sand powder container does not cover the air pressure balance port. This avoids the situation where the sand powder blocks the air pressure balance port and causes a difference in air pressure inside and outside the bottle. This improves the smoothness of pouring sand powder in the sand powder storage bottle, and thus improves the efficiency of replenishing sand powder for the sandblasting dental cleaning machine.
[0022] The sandblasting powder storage bottle provided by this utility model adopts the aforementioned sand powder leak structure. The target sand powder in the sand powder container is transported to the sand outlet through the target flow port. At the same time, the air pressure balance port can transport the target sand powder in the sand powder container to the sand outlet when the sand powder amount is more than the preset amount, and can balance the air pressure in the sand powder container when the sand powder amount is less than the preset amount. This avoids the situation where the sand powder blocks the air pressure balance port, resulting in a difference in air pressure inside and outside the bottle. This improves the smoothness of sand powder pouring in the sand powder storage bottle, thereby improving the efficiency of replenishing sand powder for the sandblasting dental cleaning machine.

[0036] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0037] Currently, air polishing is the mainstream method for cleaning teeth in dentistry. An air polishing machine sprays abrasive powder onto the tooth surface to clean it. The powder container of the air polishing machine stores the powder for later use. When the powder in the container is low, powder from the storage bottle can be poured into the container to replenish it.
[0038] In practical applications, the cap of the abrasive powder storage bottle has a small hole to balance the air pressure inside and outside the bottle, allowing the abrasive powder in the storage bottle to be poured into the abrasive powder container. However, during the pouring process, the abrasive powder easily clogs the small hole on the cap, causing a pressure difference between the inside and outside of the bottle. This prevents the abrasive powder from flowing smoothly out of the storage bottle, affecting the efficiency of replenishing abrasive powder for the abrasive blasting machine. Therefore, improving the smoothness of abrasive powder pouring from the storage bottle has become an urgent problem to be solved.
[0039] In response, this utility model discloses a sand powder outlet structure and a sandblasting sand powder storage bottle, which can improve the smoothness of sand powder pouring from the sand powder storage bottle, thereby improving the efficiency of replenishing sand powder for the sandblasting dental cleaning machine.
[0040] like Figure 1 and Figure 2As shown, this utility model discloses a sand powder leak structure, which includes a bottle cap body 100 and a sand guide tube 200. The bottle cap body 100 has a fixing hole, and a connecting side is provided on one side of the bottle cap body 100. The connecting side of the bottle cap body 100 is connected to the bottle mouth of an external sand powder container 300. The side of the bottle cap body 100 away from the sand powder container 300 is the outer side of the bottle cap body 100. The sand powder container 300 is used to collect the target sand powder. The sand guide tube 200 passes through the fixing hole of the bottle cap body 100. The sand outlet 210 of the sand guide tube 200 is provided on the outer side of the bottle cap body 100. The air pressure balance part 220 of the sand guide tube 200 is provided on the connecting side of the bottle cap body 100. The sand outlet 210 of the sand guide tube 200 has a sand outlet. The pressure balance section 220 of the sand guide tube 200 is provided with a pressure balance port at the end away from the cap body 100, and the pressure balance section 220 of the sand guide tube 200 is provided with a target flow port at the end near the cap body 100. The pressure balance port and the target flow port are connected. When the target sand powder in the sand powder container covers the pressure balance port, the target sand powder in the sand powder container 300 enters the sand guide tube 200 through the pressure balance port and the target flow port, and is then discharged through the sand outlet. When the target sand powder in the sand powder container 300 does not cover the pressure balance port, the target sand powder in the sand powder container 300 enters the sand guide tube 200 through the target flow port, and is then discharged through the sand outlet.
[0041] In this embodiment, the bottle cap body 100 has a fixing hole, and the sand guide tube 200 is a hollow vertical tubular object. The sand guide tube 200 can be inserted into the fixing hole to be fixedly connected with the bottle cap body 100. After connection, the sand guide tube 200 can be divided into an upper section and a lower section by the bottle cap body 100.
[0042] Reference Figure 1 The lower side of the bottle cap body 100 is the connecting side, through which the bottle cap body 100 connects to the sand powder container 300 containing the target sand powder. The lower section of the sand guide tube 200 located on the connecting side of the bottle cap body 100 is the air pressure balancing section 220. The upper side of the bottle cap body 100 is the outer side, and the upper section of the sand guide tube 200 located on the outer side of the bottle cap body 100 is the sand outlet section 210. A sand outlet is provided at the uppermost end of the sand outlet section 210 of the sand guide tube 200, an air pressure balancing port is provided at the lowermost end of the air pressure balancing section 220 of the sand guide tube 200, and a target flow port is provided near the bottle cap body 100 in the air pressure balancing section 220 of the sand guide tube 200. It can be understood that the opening shape and size of the target flow port can be adaptively configured according to the actual required flow rate of the sand powder.
[0043] Reference Figure 2Through the inverted sand powder outlet structure and the sand powder container 300, the target sand powder inside the sand powder container 300 tends to flow downwards due to gravity. The preset sand powder quantity threshold value depends on the length of the air pressure balance section 220. The longer the length of the air pressure balance section 220, the higher the sand powder quantity threshold value is set. That is, the sand powder quantity threshold value can reflect the height of the highest point of the air pressure balance section 220 in the sand powder container 300.
[0044] Let the sand powder quantity threshold be the amount of sand powder in the sand powder container 300 when the horizontal line of the target sand powder exactly covers the air pressure balance port. Let the amount of sand powder greater than the sand powder quantity threshold be the first sand powder quantity, and the amount of sand powder less than the sand powder quantity threshold be the second sand powder quantity. For example... Figure 2 The dashed line A is the horizontal line in the sand powder container 300 corresponding to the first sand powder amount, the dashed line B is the horizontal line in the sand powder container 300 corresponding to the second sand powder amount, and the dashed line O is the horizontal line in the sand powder container 300 corresponding to the sand powder amount threshold. When the target sand powder stored in the sand powder container 300 is the first amount, the horizontal line of the target sand powder in the sand powder container 300 is higher than the highest point of the air pressure balance section 220. At this time, the target sand powder can flow into the sand guide pipe body 200 from the air pressure balance port and the target flow port, and the sand guide pipe body 200 transports the flowing target sand powder to the sand outlet of the bottom sand outlet section 210, thereby discharging the target sand powder. When the target sand powder stored in the sand powder container 300 is the second amount, the horizontal line of the target sand powder in the sand powder container 300 is lower than the highest point of the air pressure balance section 220. At this time, the target sand powder cannot flow into the sand guide pipe body 200 from the air pressure balance port, but can only flow into the sand guide pipe body 200 from the target flow port at the bottom of the air pressure balance section 220. The air pressure balance port then serves as a passage for balancing the air pressure inside and outside the sand powder container 300, and the sand guide pipe body 200 transports the flowing target sand powder to the sand outlet, thereby allowing the target sand powder to be smoothly discharged to the outside. Understandably, in order to ensure that the air pressure balancing port can play a greater role in balancing the air pressure inside and outside the sand powder container 300, the length setting value of the air pressure balancing section 220 can be appropriately increased to increase the corresponding sand powder amount threshold, or the amount of sand powder stored in the sand powder container 300 can be appropriately reduced to ensure that the amount of sand powder is lower than the sand powder amount threshold.
[0045] As can be seen, the sand powder outlet structure of this utility model transports the target sand powder in the sand powder container 300 to the sand outlet through the target flow port. At the same time, through the air pressure balance port, it can transport the target sand powder in the sand powder container 300 to the sand outlet when the target sand powder in the sand powder container 300 covers the air pressure balance port, and can balance the air pressure of the sand powder container 300 when the target sand powder does not cover the air pressure balance port. This avoids the situation where the sand powder blocks the air pressure balance port and causes a difference in air pressure inside and outside the bottle, thereby improving the smoothness of pouring sand powder in the sand powder storage bottle, and thus improving the efficiency of replenishing sand powder for the sandblasting dental cleaning machine.
[0046] likeFigure 3 As shown, in an optional embodiment, the target flow port includes a first flow port and a second flow port, with the first flow port and the second flow port disposed opposite to each other at one end of the pressure balance section 220 of the sand guide tube 200 near the bottle cap body 100.
[0047] In this optional embodiment, refer to Figure 3 The target flow outlets are configured as a first flow outlet and a second flow outlet, which are respectively located on the left and right sides of the bottom of the air pressure balance section 220, that is, the first flow outlet and the second flow outlet are openings that are opposite to each other. It can be understood that the shape and size of the openings of the first flow outlet and the second flow outlet can be adaptively configured according to the actual required flow rate of sand powder.
[0048] As can be seen, this optional embodiment can also improve the discharge flow rate and speed of the target sand powder by configuring the target flow port as a first flow port and a second flow port that are set opposite to each other.
[0049] like Figure 3 and Figure 4 As shown, in an optional embodiment, the pressure balance port is located at the end of the pressure balance section 220 of the sand guide tube 200 away from the bottle cap body 100, with a preset first tilt direction and a preset first tilt angle.
[0050] In this optional embodiment, refer to Figure 3 The pressure balance port is positioned at the top of the pressure balance section 220 of the sand guide pipe body 200 in an inclined shape. (See reference...) Figure 4 The pressure balance port is tilted in a first inclination direction from the upper left to the lower right, and the tilt angle is a preset first inclination angle. Since the mouth of the sand powder container 300 is generally sealed with a membrane, when it is necessary to use the sand powder container 300 to pour out the target sand powder, the sand powder leak structure can pierce the membrane of the sand powder container 300 mouth through the tip of the tilted pressure balance port, achieving quick use. It is understood that the first inclination direction and the first inclination angle of the pressure balance port can be adaptively adjusted according to the actual need to reduce splashing.
[0051] As can be seen, this optional embodiment can quickly use the sand powder container 300 when the target sand powder needs to be poured out by piercing the film at the mouth of the sand powder container 300 through the tip of the inclined air pressure balance port, thereby further improving the efficiency of replenishing sand powder for the sandblasting dental cleaning machine.
[0052] like Figure 4 and Figure 5As shown, in an optional embodiment, the sand outlet is located at the end of the sand outlet 210 of the sand guide tube 200 away from the bottle cap body 100, with a preset second tilt direction and a preset second tilt angle.
[0053] In this optional embodiment, refer to Figure 5 The sand outlet is positioned at an angle at the bottom end of the sand outlet section 210 of the sand guide pipe body 200. (Refer to...) Figure 4 The abrasive outlet is tilted in a second inclination direction from the upper left to the lower right, and the tilt angle is a preset second inclination angle. When pouring the target abrasive powder, the tip of the abrasive outlet can be pointed downwards to ensure that the target abrasive powder flows down along the tip of the abrasive outlet when poured into the powder tank of the air blasting and cleaning machine, thereby reducing the amount of target abrasive powder splashing outside the powder tank. It is understood that the second inclination direction and the second inclination angle of the abrasive outlet can be adaptively adjusted according to the actual need to reduce splashing.
[0054] As can be seen, this optional embodiment can also reduce the occurrence of target sand powder splashing outside the powder canister when the target sand powder is poured into the powder canister of the sandblasting machine by making the tip of the sand outlet face downwards.
[0055] like Figure 6 As shown, in an optional embodiment, the length of the air pressure balance section 220 of the sand guide tube 200 is the same as the depth of the sand powder container 300.
[0056] In this optional embodiment, when the length of the air pressure balancing section 220 is the same as the depth of the sand powder container 300, the air pressure balancing port can maximize the balancing effect on the air pressure inside and outside the sand powder container 300.
[0057] In conjunction with the aforementioned inclined design of the air pressure balance port, referring to Figure 6 The horizontal line position (dashed line O) corresponding to the lowest tilt of the air pressure balance port is the horizontal line position corresponding to the preset sand powder amount threshold. When the sand powder amount of the target sand powder is higher than the sand powder amount threshold, the air pressure balance port only plays a guiding role for the target sand powder. When the sand powder amount of the target sand powder is lower than the sand powder amount threshold, the air pressure balance port plays a balancing role for the air pressure inside and outside the sand powder container 300. Therefore, when the length of the air pressure balance part 220 is the same as the depth of the sand powder container 300, the guiding role of the air pressure balance port is less than the air pressure balancing role, and its air pressure balancing role can be maximized.
[0058] As can be seen, this optional embodiment can maximize the balancing effect of the air pressure balance port on the air pressure inside and outside the sand powder container 300 by setting the length of the air pressure balance part 220 to be the same as the depth of the sand powder container 300.
[0059] likeFigure 3 As shown, in an optional embodiment, a connecting groove is provided on the connecting side of the cap body 100. The diameter of the connecting groove is larger than the diameter of the bottle mouth of the sand and powder container 300. The cap body 100 is fitted onto the bottle mouth of the sand and powder container 300 through the connecting groove.
[0060] In this optional embodiment, refer to Figure 3 A connecting groove is formed on the connecting side of the cap body 100, and the connecting groove can be a cylindrical groove. The diameter of the connecting groove is larger than the diameter of the mouth of the sand powder container 300, so that the cap body 100 can be fitted over the mouth of the sand powder container 300 through the connecting groove, thus preventing sand leakage from the mouth of the sand powder container 300 when pouring the target sand powder.
[0061] As can be seen, this optional embodiment can also provide a connecting groove on the connecting side of the cap body 100, and the diameter of the connecting groove is larger than the diameter of the mouth of the sand powder container 300, so that the cap body 100 can be fitted onto the outside of the mouth of the sand powder container 300 through the connecting groove, thereby preventing sand leakage from the mouth of the sand powder container 300 when pouring the target sand powder.
[0062] like Figure 3 As shown, in an optional embodiment, the bottle cap body 100 has a first threaded connection portion 110, which is helical in shape and disposed on the inner wall of the connecting groove along the axial direction of the bottle cap body 100. The bottle cap body 100 is threadedly connected to the bottle mouth of the sand powder container 300 through the first threaded connection portion 110.
[0063] In an optional embodiment, the mouth of the sand powder container 300 has a second threaded connection portion. The second threaded connection portion is spirally shaped and disposed on the outer wall of the mouth of the sand powder container 300 along the axial direction of the mouth of the sand powder container 300. The sand powder container 300 is threadedly connected to the cap body 100 through the second threaded connection portion.
[0064] In this optional embodiment, refer to Figure 3 The inner wall of the connecting groove is provided with a first threaded connection portion 110, which is helical and arranged along the axial direction of the cap body 100. The outer wall of the mouth of the powder container 300 is provided with a second threaded connection portion, which is helical and arranged along the axial direction of the mouth of the powder container 300. The cap body 100 is threadedly connected to the second threaded connection portion of the mouth of the powder container 300 through the first threaded connection portion 110, thereby increasing the sealing performance of the connection between the cap body 100 and the powder container 300.
[0065] As can be seen, this optional embodiment can also provide a first threaded connection 110 on the inner wall of the connecting groove of the bottle cap body 100 and a second threaded connection on the outer wall of the bottle mouth of the sand powder container 300, so that the bottle cap body 100 is threadedly connected to the second threaded connection of the bottle mouth of the sand powder container 300 through the first threaded connection 110, thereby increasing the sealing of the connection between the bottle cap body 100 and the sand powder container 300, thereby further avoiding the leakage of sand from the bottle mouth of the sand powder container 300 when pouring the target sand powder.
[0066] This utility model also discloses a sandblasting powder storage bottle, which includes a sand powder container 300 and the sand powder outlet structure described in the above embodiments of this utility model. The bottle mouth of the sand powder container 300 is connected to the connecting side of the bottle cap body 100.
[0067] As can be seen, in this embodiment, the sandblasting powder storage bottle adopts the aforementioned sand powder outlet structure. The target sand powder in the sand powder container 300 is transported to the sand outlet through the target flow port. At the same time, the air pressure balance port can transport the target sand powder in the sand powder container 300 to the sand outlet when the target sand powder in the sand powder container 300 covers the air pressure balance port, and can perform air pressure balance on the sand powder container 300 when the target sand powder does not cover the air pressure balance port. This avoids the situation where the sand powder blocks the air pressure balance port, resulting in a difference in air pressure inside and outside the bottle. This improves the smoothness of sand powder pouring in the sand powder storage bottle, thereby improving the efficiency of replenishing sand powder for the sandblasting dental cleaning machine.
[0068] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
