Description

Technical Field

[0001] This utility model relates to the field of oral irrigator technology, specifically to an easy-to-install oral irrigator cover structure. Background Technology

[0002] Just as a high-pressure water gun can easily clean a car, water jets of appropriate pressure have long been proven to effectively clean teeth and the oral cavity. The cleaning effect of a water flosser is mainly achieved by the impact force of a high-speed jet of water sprayed under certain pressure. A water flosser is an auxiliary tool for cleaning the oral cavity, using pulsed water jets to clean teeth and between teeth; the rinsing pressure is generally between 0 and 90 ps i.

[0003] However, the top cover of existing water flossers usually needs to be fixed with multiple screws during installation. However, the process of tightening the screws takes a long time and usually requires the help of tools, so it is not convenient to install the top cover of the water flosser. Utility Model Content

[0004] The present invention aims to provide a water flosser cover structure that is easy to install, mainly to solve the technical problem in the prior art where it is inconvenient to install the water flosser cover by unscrewing multiple screws.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An easy-to-install oral irrigator cover structure includes an oral irrigator body, a cover, and a pressure plate. Multiple guide posts are fixedly connected to the upper surface of the oral irrigator body. Insertion holes are opened on the upper surface of the pressure plate. The pressure plate covers the upper surface of the oral irrigator body, and the guide posts are inserted into the insertion holes. A fixing cylinder that matches the guide posts is fixedly connected to the inner wall of the cover. The guide posts are inserted into the fixing cylinder, and the fixing cylinder is inserted into the insertion holes. A limit component is installed on the inner wall of the fixing cylinder.

[0007] The working principle and beneficial effects of this utility model:

[0008] 1. Working principle: When the top cover needs to be installed, first place the pressure plate into the placement slot on the water flosser body, so that the guide post is inserted into the socket and passes through the socket. Then, put the top cover on the upper surface of the water flosser body, so that the fixing cylinder is inserted into the guide post. When the guide post is inserted into the fixing cylinder, the fixing cylinder is also inserted into the socket. At this time, the guide post is limited by the limiting component inside the fixing cylinder, thus completing the fixation.

[0009] 2. Beneficial effects:

[0010] This solution addresses technical issues by incorporating a top cover, pressure plate, guide post, fixing cylinder, limiting ball, and spring. During installation, the pressure plate is placed in the placement slot, and then the top cover is placed on the main body of the water flosser, allowing the fixing cylinder to insert into the guide post. At this time, the fixing cylinder also inserts into the hole on the pressure plate. Then, the limiting ball enters the interior of the fixing cylinder and contacts the lower surface of the spring. When the top cover is fully closed, the limiting ball presses against the spring, causing the limiting ball to move to the upper surface of the spring. The spring then limits the limiting ball, avoiding the use of screws for fixing, making the top cover more secure, reducing screwing time, and improving production efficiency.

[0011] Preferably, the limiting component includes a limiting ball, which is fixedly connected to the upper surface of the guide post. Multiple spring clips are fixedly connected to the inner wall of the fixing cylinder. The lower end of each spring clip is fixedly connected to the inner wall of the fixing cylinder, and the upper end of each spring clip is slidably connected to the inner wall of the fixing cylinder. The limiting ball is located inside the fixing cylinder and abuts against the upper surface of the spring clips. By setting the limiting component, when the guide post and the fixing cylinder are inserted, the limiting ball compresses the spring clips and abuts against the upper surface of the spring clips, which can effectively improve the stability of the top cover fixed to the water flosser body, preventing the guide post from detaching from the fixing cylinder. At the same time, the installation of the top cover is also more convenient and quick.

[0012] Preferably, the upper surface of the water flosser body has a slot, and the lower surface of the top cover is fixedly connected to a retaining ring that matches the slot, with the retaining ring inserting into the slot. By setting the slot and retaining ring, the gap between the top cover and the water flosser body can be protected, preventing water from directly entering the interior of the slot, while also improving the stability of the top cover.

[0013] Preferably, a nozzle is provided on the upper surface of the cover, and the nozzle is connected to the interior of the oral irrigator body. By providing the nozzle, the patient's teeth can be effectively cleaned.

[0014] Preferably, the end of the fixing cylinder and the retaining ring furthest from the top cover is rounded. This prevents the corners of the fixing cylinder from pressing against the corners of the guide post during top cover installation, thus avoiding damage to the corners. It also guides the installation of the guide post, making installation more convenient.

[0015] Preferably, the upper surface of the water flosser body has a placement groove, and the pressure plate is placed inside the placement groove, with the height of the pressure plate flush with the upper surface of the water flosser body. The top cover is more securely fixed to the upper surface of the water flosser body, and the placement groove for the pressure plate saves space in the water flosser body.
