The technical solution has the following technical effects:

[0016] The utility model provides a mounting hole located above the mounting bracket and a guide ring passing through the mounting hole and extending towards the mounting bracket, so that when installing the filter element, the user aligns the filter element with the mounting hole and moves the filter element vertically downward through the mounting hole on the top plate to move the filter element to the filter element mounting position on the mounting bracket to complete the installation of the filter element. During this process, the guide ring can guide the filter element passing through the mounting hole and guide the filter element to move vertically to the filter element mounting position on the mounting bracket to avoid the filter element from tilting or horizontally moving. The structural setting of the guide ring passing through the mounting hole and extending towards the mounting bracket can fill the gap between the bottom of the top plate and the top of the mounting bracket to prevent the gap between the two from being too large to produce a step difference, thereby preventing the end of the filter element from being stuck in the gap during the installation process, causing assembly jams, reducing the difficulty of installing the filter element, and making the installation smoother when the user replaces the filter element, thereby improving the efficiency of element replacement and the user's experience.

[0017] The mounting bracket includes a mounting barrel, which is coaxially arranged with a guide ring for accommodating a filter element. The central axis of the mounting barrel is coaxially arranged with the central axis of the guide ring, so that the guide ring and the mounting barrel are completely aligned. When the user installs the filter element, the filter element is just aligned with the mounting barrel under the guidance of the guide ring, avoiding misalignment of the filter element and the mounting barrel in the horizontal direction, and making the installation smoother.

[0018] The bottom surface of the guide ring is against the top surface of the mounting tube, that is, the guide ring completely fills the gap between the top plate and the top of the mounting tube, so that the filter element is always guided by the guide ring before entering the mounting tube, and the guiding effect is better. The inner wall of the guide ring is flush with the inner wall of the mounting tube, that is, the inner diameter of the guide ring is the same as the inner diameter of the mounting tube, so that when the filter element slides down, it will not get stuck when it changes from sliding down against the inner wall of the guide ring to sliding down against the inner wall of the mounting tube, and the installation is smoother and more reliable.

[0019] The bottom of the guide ring and the top of the installation tube are respectively provided with a plug-in protrusion and a plug-in groove, and the guide ring and the installation tube are plugged in through the plug-in protrusion and the plug-in groove. Through the cooperation of the plug-in protrusion and the plug-in groove, the guide ring and the installation tube can be installed and positioned to ensure that the guide ring and the installation tube are fully aligned, which is convenient for quickly aligning the guide ring and the installation tube when assembling the guide ring, thereby improving assembly efficiency.

[0020] The mounting bracket also includes a frame body arranged at the lower part of the mounting cylinder. The frame body and the mounting cylinder are an integrated structure to facilitate the production and processing of the mounting bracket. There is no need to assemble the mounting bracket, which simplifies the assembly steps of the mounting bracket and improves the assembly efficiency of the desktop water purifier.

[0021] The mounting bracket also includes a filter element seat located at the bottom of the mounting barrel, and the filter element seat is mounted on the frame. By mounting the filter element seat on the frame, it is not necessary to set the mounting position of the filter element seat on the mounting barrel, simplifying the structure of the mounting barrel and thus reducing the space occupied by the mounting barrel.

[0022] The upper part of the mounting cylinder is sleeved on the outer peripheral side of the lower part of the guide ring, the outer wall of the guide ring is abutted against the inner wall of the mounting cylinder, and the part of the guide ring extending into the mounting cylinder can continuously guide the filter element sliding down from the guide ring into the mounting cylinder, and the mounting cylinder is sleeved on the outside of the guide ring, so that the mounting cylinder will not extend into the inside of the guide ring to hinder the sliding of the filter element, thereby facilitating the installation of the filter element.

[0023] The guide ring and the top plate are separate structures, and the guide ring can be detachably connected to the top plate. By separating the guide ring and the top plate, when assembling the tabletop water purifier, guide rings of different heights can be selected and installed on the top plate according to the gap height between the top of the mounting bracket and the top plate, making the assembly more flexible. At the same time, the detachable connection structure allows the guide ring to be replaced separately when it is severely worn or damaged, reducing the cost of maintenance and replacement.

[0024] The guide ring includes a ring body and a surrounding edge provided on the outer peripheral side of the ring body. The ring body is inserted into the mounting hole, and the surrounding edge abuts against the outer peripheral side of the top of the mounting hole. When the guide ring is installed on the top plate, the ring body is inserted into the mounting hole, and the outer wall of the ring body abuts against the inner wall of the mounting hole to limit the guide ring in the horizontal direction, and the bottom surface of the surrounding edge abuts against the top surface of the top plate to limit the guide ring in the vertical direction to prevent the guide ring from sliding down, ensuring that the guide ring can always fill the gap between the top plate and the mounting bracket, stably guide the filter element during installation, and facilitate the installation of the filter element.

[0025] A groove opening upward and a top cover for covering the groove are provided on the top plate, the mounting hole is provided in the groove, and the top cover covers the groove, thereby shielding the mounting hole in the groove and the mounting cylinder aligned with the mounting hole, so that the dustproof effect of the filter element in the mounting cylinder is good. At the same time, the top cover is limited by the groove to prevent the top cover from freely displacing in the horizontal direction, thereby ensuring that the top cover shields the filter element in the mounting hole.
