Description

Technical Field

[0001] This utility model relates to the field of FFU purification equipment technology, specifically a novel FFU purification unit. Background Technology

[0002] FFU is a self-powered, modular terminal air supply device with filtration function. It combines a fan and a filter to form a self-powered terminal purification device, which is widely used in clean rooms, clean benches, clean production lines and other occasions.

[0003] For example, the utility model patent disclosed in publication number CN217207052U discloses an FFU purification unit, including a purification fan, a fan unit, a baffle mounted on the fan unit, and fastening components for fixing the baffle. The purification fan is fixedly installed in the middle of the fan unit, and the top of the purification fan is fixedly connected to support strips on both sides of the fan unit. The baffle is located on the top of the fan unit and is snapped into the fan unit. The surface of the baffle is hollowed out. This utility model, through the purification fan, in conjunction with the fan unit, under the support of the support strips, allows the baffle to be stably fixed to the through holes opened on the support strips by the fastening components. In addition, with the internally connected filter screen and filter frame, the filtration unit can better filter the delivered air again, reducing the problem of dust covering the baffle.

[0004] Although the aforementioned purification unit can purify incoming air, it is not convenient to quickly and easily disassemble and replace the purification components, which reduces the ease of subsequent maintenance of the purification unit. Therefore, there is an urgent need for a new type of FFU purification unit to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a novel FFU purification unit to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel FFU purification unit, comprising a supporting housing, a fixed handle symmetrically arranged on the side end face of the housing, an air guide fan symmetrically arranged on the upper part of the inner end face of the housing, and a support guide seat arranged on the upper end face of the housing, with a dustproof net symmetrically arranged on the inner end face of the support guide seat.

[0007] The high-efficiency filter is fixedly clipped to the lower end face of the housing. Four sets of positioning devices are equidistantly arranged on the upper end face of the high-efficiency filter. The positioning devices are used for positioning and guiding.

[0008] A limiting device is symmetrically arranged on the inner end face of the housing, and the limiting device is used to limit and lock the high-efficiency filter.

[0009] Preferably, the positioning device includes an alignment base, a limiting pin is provided at the middle of the upper end face of the alignment base, and a positioning guide groove is provided on the inner end face of the limiting pin.

[0011] Preferably, the limiting pin is fixedly mounted on the upper surface of the high-efficiency filter via the alignment base, which facilitates quick and easy installation of the limiting pin.

[0012] Preferably, the limiting pin shaft drives the guide ramp to move backward inside the fixed card seat via the alignment pin shaft. When installing and disassembling the high-efficiency filter, the alignment pin shaft can provide sufficient clearance for the upward movement of the limiting pin shaft, thereby improving the convenience of subsequent alignment and limiting of the positioning guide groove and the guide ramp.

[0013] Preferably, the limiting slide is adapted to the positioning guide groove through the guide slope and then fixedly engaged with the limiting pin. The insertion and limiting of the four sets of guide slopes and positioning guide grooves can effectively improve the stability of the subsequent locking and limiting of the high-efficiency filter at the bottom of the housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a positioning device and a limiting device, enables the positioning baffle to drive the guide slope to move stably backward inside the fixed card seat during the quick and convenient disassembly operation of the high-efficiency filter through the limiting slide, thereby releasing the limiting of the guide slope to the positioning guide groove, thus facilitating the quick and convenient disassembly of the high-efficiency filter. At the same time, during assembly, the alignment insert shaft can provide sufficient clearance and guiding space for the limiting card shaft, effectively improving the convenience and accuracy of subsequent alignment and limiting between the limiting card shaft and the guide slope, thereby improving the convenience of subsequent disassembly and assembly of the high-efficiency filter, and also improving the practical performance of the equipment.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides an embodiment of a novel FFU purification unit, comprising a supporting housing 6, a fixed handle 5 symmetrically arranged on the side end face of the housing 6, an air guide fan 1 symmetrically arranged on the upper part of the inner end face of the housing 6, a support guide seat 7 arranged on the upper end face of the housing 6, and a dustproof net 8 symmetrically arranged on the inner end face of the support guide seat 7.

[0024] The high-efficiency filter 3 is fixedly clipped to the lower end face of the housing 6. Four sets of positioning devices 2 are equidistantly arranged on the upper end face of the high-efficiency filter 3. The positioning devices 2 are used for positioning and guiding.

[0025] Limiting device 4 is symmetrically arranged on the inner end face of housing 6. Limiting device 4 is used to limit and lock the high-efficiency filter 3.

[0026] The positioning device 2 includes a positioning base 21, a limiting pin 22 is provided at the middle of the upper end face of the positioning base 21, and a positioning guide groove 23 is provided on the inner end face of the limiting pin 22.

[0027] The limiting device 4 includes a fixed bracket 44, the inner end face of which is slidably engaged with a limiting slide 46. A guide slope 41 is provided at the center of the front end face of the limiting slide 46, and an alignment insert shaft 42 is provided at the front of the guide slope 41. A return spring 47 is provided at the center of the rear end face of the limiting slide 46. A positioning baffle 43 is provided at the front of the limiting slide 46, and support springs 45 are provided at the front end face of the limiting slide 46 opposite to the positioning baffle 43.

[0028] The limiting pin 22 is fixedly mounted on the upper surface of the high-efficiency filter 3 via the alignment base 21, which facilitates quick and easy installation of the limiting pin 22.

[0029] The limiting pin 22 drives the guide slope 41 to move backward inside the fixed seat 44 via the alignment pin 42. When installing and disassembling the high-efficiency filter 3, the alignment pin 42 can provide sufficient clearance for the upward movement of the limiting pin 22, thereby improving the convenience of subsequent alignment and limiting of the positioning guide groove 23 and the guide slope 41.

[0030] The limiting slide 46 is adapted to the positioning guide groove 23 through the guide slope 41 and then fixedly engaged with the limiting pin 22. The insertion and limiting of the four sets of guide slopes 41 and positioning guide grooves 23 can effectively improve the stability of the subsequent high-efficiency filter 3 locked and limited at the bottom of the housing 6.

[0031] Working principle: During use, the operator can position the equipment in a suitable location to facilitate subsequent air supply operations. If the HEPA filter 3 needs to be replaced after prolonged use, the operator can press the positioning baffles 43 on both sides. The positioning baffles 43 can drive the limiting slide 46 to move inward. At this time, the limiting slide 46 can drive the guide slope 41 to separate from the positioning guide groove 23. Subsequently, the HEPA filter 3 will separate from the bottom of the housing 6 under the action of gravity. At the same time, a new set of HEPA filters 3 can be installed. During assembly, the user can align the HEPA filter 3 with the bottom of the housing 6 and press it up. At this time, the four sets of limiting pins 22 can be directly positioned at the alignment pin 42. Then, the limiting pins 22 can drive the guide slope 41 and the limiting slide 46 to move backward through the alignment pin 42, so that the limiting pins 22 pass through the fixed pin 44. As the limiting pins 22 continue to rise, the return spring 47 can drive the guide slope 41 to be inserted into the positioning guide groove 23, thus completing the replacement limiting operation of the HEPA filter 3.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
