Description

Technical Field

[0001] This utility model relates to the field of dental irrigator technology, specifically to a periodontal irrigator water column pressure regulating mechanism and a periodontal irrigator. Background Technology

[0002] An oral irrigator is a device used for oral hygiene care, also known as a dental irrigator or dental scaler. It typically uses high-pressure water or a mixture of water streams to clean teeth, gums, and periodontal tissues, providing a comprehensive oral cleaning. The working principle of an oral irrigator is to use high-pressure water to rinse the tooth surface and gum line, removing plaque, food debris, and bacteria to promote oral hygiene and prevent oral diseases. In addition, hospital dental departments often use periodontal irrigators to rinse the gums and periodontal pockets with a liquid medication (such as saline solution and hydrogen peroxide), followed by the application of iodine glycerin for anti-inflammatory and antibacterial effects.

[0003] Because different users have varying tolerance levels and preferences, the water pressure of periodontal irrigators generally needs to be adjusted to meet their actual needs. Currently, there are many irrigators on the market with adjustable water pressure, such as the Chinese invention patent CN110151344A "A Self-Adjusting Intelligent Electric Irrigator for Irrigation Pressure", the Chinese invention patent CN119454270A "An Irrigator for Irrigating Water Pressure by Pressure Sensing", and the Chinese utility model patent CN217525458U "An Irrigator for Irrigating Water Pressure with Self-Adjusting Pressure", all of which allow for adjustable water pressure.

[0004] However, the dental irrigators mentioned above all require the installation of pressure sensors and controllers. By sensing the pressure signal pressed and feeding it back to the controller, the pump speed or valve opening is controlled to adjust the flushing water pressure. Since they involve electronic components such as pressure sensors, controllers, and power supplies, their structure is generally quite complex. Furthermore, dental irrigators are frequently exposed to water during use and are prone to malfunction due to moisture. In addition, their production and maintenance costs are relatively high.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit its scope of protection.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0040] like Figure 1 , Figure 2 as well as Figure 3 As shown, one embodiment of this utility model provides a water column pressure regulating mechanism for a periodontal cleaner, which includes a first conduit 1, a pressure regulating chamber 2, a second conduit 3, a first regulating component 4, and a first elastic component 5.

[0041] One end of the first conduit 1 is connected to the nozzle of the periodontal cleaner, and the other end is connected to the pressure regulating chamber 2. The pressure regulating chamber 2 is located between the first conduit 1 and the second conduit 3, and one end of the second conduit 3 is connected to the pressure regulating chamber 2, while the other end of the second conduit 3 is connected to the water storage chamber 14 of the periodontal cleaner.

[0042] The first adjusting component 4 passes through the side wall of the housing 6 of the periodontal cleaner and is slidably and sealingly connected to the side wall of the housing 6, and is inserted into the pressure regulating cavity 2. Specifically, the pressure regulating cavity 2 is square, the first adjusting component 4 can be a slider, and the first adjusting component 4 is slidably and sealingly connected to the side wall of the pressure regulating cavity 2 to ensure that water will not flow out from the connection between the first adjusting component 4 and the pressure regulating cavity 2 when the periodontal cleaner is working.

[0043] like Figure 3As shown, both the first conduit 1 and the second conduit 3 are located at the end of the pressure regulating chamber 2 away from the first regulating component 4. A first elastic component 5 is mounted on the first regulating component 4 to provide a pressing and restoring elastic force to the first regulating component 4. This first elastic component 5 is preferably a helical spring, which is sleeved on the first regulating component 4 and located between the side wall of the pressure regulating chamber 2 and the housing 6.

[0044] The first adjusting component 4 is used to adjust the volume of the pressure regulating chamber 2 that connects the first conduit 1 and the second conduit 3. When the user presses the first adjusting component 4, one end of the first adjusting component 4 slides into the pressure regulating chamber 2, reducing the volume of the pressure regulating chamber 2. This gradually narrows the connection between the first conduit 1 and the second conduit 3. With a constant motor speed of the periodontal cleaner's water pump, the water flow velocity through the connection (i.e., the pressure regulating chamber 2) is strong, increasing the flushing water pressure flowing out of the first conduit 1 and the nozzle. When it is necessary to reduce the flushing water pressure, the first adjusting component 4 is loosened appropriately, causing it to move away from the pressure regulating chamber 2 under the elastic force of the first elastic component 5, increasing the volume of the pressure regulating chamber 2, thus achieving the operation of reducing the flushing water pressure.

[0045] In summary, the periodontal cleaner water column pressure regulating mechanism adjusts the volume of the pressure regulating chamber 2 between the first conduit 1 and the second conduit 3 by driving the first regulating component 4 to move. It can adjust the nozzle flushing water pressure through a mechanical structure without involving electronic components. Compared with the existing technology of dental irrigators that rely on pressure sensors and controllers to adjust the flushing water pressure, its overall structure is simpler, the water column pressure regulating mechanism will not be affected by moisture or water ingress, and the cost is lower, making it very practical.

[0046] Some existing oral irrigators use a mechanical structure to compress the water hose, thereby adjusting the water pressure. For example, Chinese utility model patent CN202121028852.3, entitled "A Portable Oral Irrigator with Adjustable Water Pressure," uses a knob to compress the hose via a locking block and a U-shaped clamp. This compression controls the water flow through the hose, and the water pressure from the nozzle is adjusted based on the water flow rate, allowing for convenient pressure control according to needs. However, this portable oral irrigator lacks coarse and fine-tuning of the water pressure, making precise pressure regulation difficult, and its structure needs improvement.

[0047] To address the aforementioned problems, as a preferred technical solution, such as Figure 4 As shown, the water column pressure regulating mechanism also includes a support block 7, a squeezing block 8, and a second regulating component 9.

[0048] The support block 7 is fixedly installed inside the housing 6 and located on one side of the first conduit 1. It has a sliding cavity 10 perpendicular to the length direction of the conduit. The squeezing block 8 is slidably installed inside the sliding cavity 10 and one end abuts against the first conduit 1.

[0049] The second adjusting component 9 passes through and is threadedly connected to the side wall of the housing 6, and is used to drive the extrusion block 8 to move along the sliding cavity 10 toward the first conduit 1. A rigid baffle can also be provided between the side of the first conduit 1 away from the extrusion block 8 and the housing 6. The rigid baffle is in close contact with the first conduit 1 so that when the extrusion block 8 extrudes the first conduit 1, the channel size of the first conduit 1 in contact with the extrusion block 8 can be smoothly reduced.

[0050] The first conduit 1 is a flexible tube. Since the first conduit 1 is a flexible tube and the squeezing block 8 abuts against it, driving the squeezing block 8 to move towards the first conduit 1 deforms it, thus reducing the size of the channel in contact with the squeezing block 8. With a constant periodontal cleaner pump motor speed, reducing the size of the channel in contact with the squeezing block 8 increases the flushing water pressure from the nozzle. To reduce the flushing water pressure, the second adjusting component 9 drives the squeezing block 8 away from the first conduit 1.

[0051] Specifically, the second adjusting component 9 includes a first adjusting bolt 11 and a second adjusting bolt 12.

[0052] One end of the first adjusting bolt 11 faces the pressing block 8 and extends into the sliding cavity 10; one end of the second adjusting bolt 12 faces the pressing block 8 and extends into the sliding cavity 10; wherein the diameter of the first adjusting bolt 11 is larger than the diameter of the second adjusting bolt 12. Generally, the diameter of the first adjusting bolt 11 is three or four times the diameter of the second adjusting bolt 12.

[0053] The diameter of the first adjusting bolt 11 is set to be larger than that of the second adjusting bolt 12. This allows the user to coarsely adjust the position of the squeezing block 8 using the first adjusting bolt 11, reducing adjustment time, and to finely adjust the position of the squeezing block 8 using the second adjusting bolt 12, improving the accuracy of the flushing water pressure adjustment. By combining coarse and fine adjustments, the flushing water pressure can be adjusted more accurately.

[0054] Preferably, such as Figure 4As shown, the water column pressure regulating mechanism further includes a second elastic component 13, which can be a helical spring. The two ends of the second elastic component 13 are respectively fixedly connected to the end of the squeezing block 8 away from the first conduit 1 and the housing 6, and are sleeved on the first adjusting bolt 11 and the second adjusting bolt 12 to provide restoring elasticity to the squeezing block 8. Through the second elastic component 13, when the second adjusting component 9 is rotated out, the squeezing block 8 moves away from the first conduit 1 under the elastic force of the second elastic component 13, thereby increasing the channel size of the first conduit 1 in contact with the squeezing block 8 and reducing the flushing water pressure.

[0055] It should be noted that the first conduit 1, pressure regulating chamber 2, second conduit 3, first adjusting component 4, and first elastic component 5 in this invention can serve as a first water column pressure regulating assembly, while the support block 7, squeezing block 8, second elastic component 13, and second adjusting component 9 can serve as a second water column pressure regulating assembly. The first water column pressure regulating assembly allows users to easily adjust the rinsing water pressure in real time to suit their gum tolerance and personal preferences, while the second water column pressure regulating assembly allows users to easily set a constant rinsing water pressure that suits them.

[0056] One embodiment of this utility model also provides a periodontal cleaner, such as... Figure 1 as well as Figure 2 As shown, it includes the water column pressure regulating mechanism of the periodontal cleaner. The periodontal cleaner includes a housing 6, which has a water storage cavity inside, and a rubber pad at the bottom of the housing 6.

[0057] The periodontal cleaner also includes a water pump motor for pumping water from the water storage cavity to the first conduit 1 through the second conduit 3. Since the installation of the water pump motor and related components such as batteries and check valves are conventional techniques in this field, they will not be described in detail here.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
