DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Example

[0029] This embodiment provides a filter flip structure that can be quickly disassembled and replaced. The flip structure is arranged in the storage box 2 in the housing assembly of the physiotherapy instrument. By setting the flip structure, it is convenient to quickly disassemble and replace the filter in the storage box. Figure 1 and Figure 3 As shown, the flip structure includes a pipeline rebound component 3, a filter component 4 and a flip stop component 5, etc.

[0030] Specifically, see Figure 1 and Figure 2 The pipeline rebound assembly is arranged on the upper rear side of the storage box, and includes a limit plate 31, a limit clamp 32, an air pipe 33, a single-head spring sleeve 34, a telescopic spring 35 and a double-head spring sleeve 36, etc., wherein the limit plate 31 is an L-shaped structure, and the side wall of the limit plate is fixedly installed on one side of the storage box by bolts, and a series of through holes are evenly opened on the top, and an air pipe is correspondingly installed in each through hole. Each air pipe extends vertically downward and passes through the storage box to the inside thereof, and is connected to the filter in the storage box.

[0031] like Figure 2 As shown, a telescopic spring 35 is sleeved on the trachea body between the limit plate and the top of the storage box. The top of the telescopic spring is fixedly connected to a single-head spring sleeve 34, and the bottom is sleeved and fixed with a double-head spring sleeve 36, and the bottom of the double-head spring sleeve is sleeved on the top opening of the storage box. A limit clamp 32 is sleeved and fixed on the trachea body above the single-head spring sleeve. When the equipment is in normal use, the trachea is connected to the filter, and the trachea pulls the limit clamp 32 downward. At this time, the telescopic spring is in a compressed state. When the filter needs to be replaced and disassembled, the trachea is separated from the filter, the telescopic spring is loosened, and the limit clamp is forced to drive the trachea to rebound, making room for the subsequent flipping, replacement and disassembly of the filter, and the rebound of the telescopic spring and the position of the trachea are limited by the limit plate.

[0032] like Figure 3 and Figure 4 As shown, the filter assembly 4 is arranged inside the storage box, and the filter assembly includes a filter 44, wherein a locking buckle 43 is fixedly mounted above the filter, and a filter cover 42 is arranged above the locking buckle. The upper and lower ends of the filter 44 are trachea quick-insert structures 41, and both ends can be connected to a PU hard tube with an outer diameter of 6 mm. The trachea quick-insert structure is used to connect to the upstream and downstream tracheas respectively. The trachea can be directly inserted into the filter through the trachea quick-insert structure, but the trachea cannot be directly pulled out, and the top ring of the trachea quick-insert structure needs to be pressed to pull it out smoothly.

[0033] See also Figure 4 and Figure 5 , the filter 44 is fixedly mounted on a fixed plate 46 through a filter buckle 45, the fixed plate is vertically provided with a storage box interior, and the fixed plate 46 is provided with a group of mounting holes having the same number as the filter, and each group of mounting holes includes two pairs of upper and lower mounting holes 47 for the filter buckle to match and insert, so that the filter is fixed and constrained on the fixed plate. Furthermore, an annular groove extends up and down on one side of the filter buckle, and the filter 44 can be matched and inserted into the annular groove of the filter buckle to achieve the fixation of the two, and the other side of the filter buckle is connected to the fixed plate by screws. And the middle part of the filter installed on the fixed plate is made of transparent material, and a replaceable filter element 6 is installed inside, and the filtering condition of the filter can be judged by the impurities filtered by the filter element.

[0034] The bottom of the fixed plate is movably mounted in the storage box through a fixed-angle movable hinge group 48 arranged at intervals, and the fixed-angle movable hinge group 48 drives the filter to flip back and forth, thereby facilitating the replacement operation of the filter element. Figure 6 As shown, the fixed-angle movable hinge group includes an upper hinge 481, a lower hinge 483, etc., and the upper and lower hinges are hinged by a hinge shaft 482, wherein the upper hinge is fixedly mounted on the fixed plate 46 by screws, and the lower hinge is laterally fixed to the bottom plate of the storage box.

[0035] The upper hinge 481 is also provided with an angle control seat 485 on one side close to the hinge shaft 482. The bottom of the angle control seat is fixed to the top surface of the upper hinge, and a shaft hole matching the hinge shaft is opened on the side close to the lower hinge. The angle control seat is sleeved on the hinge shaft through the shaft hole. Figure 6 The end of the angle control seat close to the lower hinge side is an arc-shaped structure, and arc-shaped grooves are spaced apart on its outer wall. This arrangement realizes the rotation angle control of the filter and the fixed plate by abutting against the top shaft 486 in the lower hinge fixing seat, so that the overall rotation angle of the filter is 90°-180°, but it will pause and be fixed at the rotation angles of 90°, 135°, and 180°; and during installation, the fixed-angle movable hinge group can be expanded to 180°, so that the lower hinge can be fixed on the storage box. When the equipment is in normal use, the filter fixing plate is driven by the upper hinge to be in the 90° direction.

[0036] like Figure 6 As shown, a fixing seat 484 is provided laterally on the top surface of the lower hinge, and a mounting groove 489 is opened in the fixing seat, in which a spring 487 is provided, and a top shaft 486 is fixedly connected to the left side of the spring, and the top shaft is a horizontal convex structure, and the end with a smaller inner diameter extends out of the mounting groove, and the end is an arc-shaped surface for matching and contacting with the arc-shaped groove on the angle control seat; a hexagon socket screw 488 is screwed into the mounting groove on the right side of the spring, and the spring is tightened by the headless hexagon socket screw; when the upper hinge is controlled to flip, the angle control seat can press the top shaft 486, so that it can move freely in the mounting groove, and it will stop and be fixed at the positions of rotation angles of 90°, 135°, and 180°, so as to facilitate the adjustment of the filter to the optimal replacement position.

[0037] like Figure 7 and Figure 8As shown, the flip stop assembly 5 is arranged on the outside of the filter, including a cover plate 51, and is rotatably mounted with the side wall of the housing assembly through the rotating parts 54 on both sides of the bottom of the cover plate. Observation holes 52 are opened on the cover plate at positions corresponding to the filters. The filters inside the storage box can be monitored in real time through the observation holes 52, so that the conditions of the filters can be grasped at any time. Magnets 53 are fixed at intervals above the observation holes, and magnet holes are provided at corresponding positions of the storage box. When the cover plate is vertically buckled outside the filter, the magnets on the cover plate are correspondingly inserted into the magnet holes on the storage box, so that the cover plate is adsorbed on the storage box in a closed state; when it is observed that the filter impurities have passed and need to be replaced, the magnet in the magnet hole can be pulled out of the adsorption state to open the cover plate, and the bottom of the cover plate is connected and rotated with the housing assembly through the rotating shaft of the rotating part.

[0038] like Figure 8 As shown, the rotating part includes grooves 55 symmetrically arranged on both sides below the fixed plate, and a top spring 57 is installed in the groove. The outer end of the top spring is fixedly connected to a rotating shaft 56. The outer end of the rotating shaft extends out of the groove in a natural state and is inserted into the shaft hole on the side wall of the housing assembly. During normal rotation, the rotating shaft is embedded in the housing bushing and the spring is used to prevent the rotating shaft from retracting. During installation and disassembly, a hard object can be used at the opening of the rotating shaft on the cover plate to move the groove on the rotating shaft, and the rotating shaft drives the spring to retract into the cover plate, which is convenient for installation and disassembly.

[0039] The invention provides a filter flip structure that can be quickly disassembled and replaced. When it is actually used, refer to Fig. 9 , first observe the observation hole 52 on the cover plate, observe the filter 44 inside the storage box, and determine whether the filter element 6 needs to be replaced; if the filter element needs to be replaced, first detent the magnet 53 in the magnet hole to make the cover plate 51 out of the adsorption state, then open the cover plate, press the top ring of the filter cover, and the air pipe will automatically retract upward due to the force of the rebound structure after being disconnected, then move the filter fixing plate connected to the fixed angle movable hinge, and stop when it pauses at 135°, then the filter element can be cleaned and replaced; to replace the filter element, it is necessary to move the filter buckle to the open state, unlock the filter 44 from the filter buckle, and then rotate and screw out the filter cover, driving the filter element to be taken out together, and then after cleaning and replacing, screw the filter element into the filter, and then move the filter buckle to the closed state, then push the filter fixing plate back, and then pull the rebound air pipe to insert the filter cover. After completing the filter element replacement, re-fasten the cover plate 51 on the outside of the filter, and the replacement process can be completed by adsorption and fixation by the magnet 53.

[0040] The novel filter flip structure provided by the present invention can be quickly disassembled and replaced, so that the disassembly and replacement process of the filter is faster and simpler; the complexity and frequency of maintenance are reduced, thereby reducing the maintenance cost.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
