[0002] There are many negative pressure and positive pressure products in the medical and beauty industries, and most of these products have pressure. Regardless of whether these pressure products are positive or negative pressure, they need to filter out impurities in the air during use to prevent them from entering the back-end beauty equipment and ensure the cleanliness of the inside of the machine. At the same time, in order to prevent the filter from being blocked and extend the service life of the equipment, it is also necessary to regularly clean and replace the filter element inside the filter, and thus auxiliary products such as filters have appeared on the market.

[0003] Although the existing filters are relatively mature, the following problems still exist:

[0004] 1. When filtering gas, not only gas enters the filter, but also colloid or some unknown liquid. With the long-term use of the equipment, more and more colloid or liquid accumulates inside the filter. However, when the colloid or liquid is full, the filter has no prompt or alarm pause function and cannot provide timely feedback. If the machine is still operated on this basis, it will damage the equipment and reduce the service life of the filter.

[0005] 2. Some of the existing filters on the market do not use filter cores in order to reduce costs, but are just simple filter tanks. Some are equipped with filter cores, but the filter cores are complicated to disassemble and assemble, and are very inconvenient to replace during use, which affects the use of the filters.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Depend on Figures 1 to 6A shell 10 is provided, wherein the shell 10 comprises an upper connecting cover 11 and a lower collecting barrel 12, wherein the collecting barrel 12 is used to collect sewage or colloid carried in the gas, and an upper and lower air inlet pipe 111 and an air outlet pipe 112 are arranged on one side of the connecting cover 11, wherein the air inlet pipe 111 is located below the air outlet pipe 112, and a connecting cylinder 13 is coaxially fixed inside the connecting cover 11, wherein the connecting cylinder 13 is connected to the air outlet pipe 112, and an air inlet cylinder 14 is fixed inside the connecting cover 11. In this embodiment, the air inlet cylinder 14 is composed of an arc-shaped plate and the inner wall of the connecting cover 11. When the filter is cleaned, the air inlet cylinder 14 must also be cleaned. The air inlet cylinder 14 is connected to the air inlet pipe 111, and the inner coaxial card of the connecting cylinder 13 A connecting seat 20 is connected, and an air outlet channel 201 is coaxially opened in the connecting seat 20. A suspension component is slidably provided at the bottom of the connecting seat 20. A filter core 30 located above the connecting seat 20 is provided inside the connecting cylinder 13. Through the air inlet pipe 111, the air outlet pipe 112 and the filter core 30, the gas enters the shell 10 through the air inlet pipe 111. When initially entering the shell 10, the gas enters the collecting barrel 12 below through the guidance of the air inlet cylinder 14. The sewage or colloid carried in the gas is mainly gathered in the collecting barrel 12, and then passes through the suspension component, the connecting seat 20 and the filter core 30. After being filtered by the filter core 30, the impurities carried in the gas are filtered out and finally ejected from the air outlet pipe 112. The air outlet pipe 112 can be directly connected to the corresponding beauty equipment;

[0030] Considering that the replacement of the filter element 30 in the existing filter is too cumbersome, the suspension component includes a suspension seat 40 matched with the connecting cover 11, a through hole is coaxially opened in the suspension seat 40, a connecting pin 41 is coaxially fixed in the through hole, an air inlet channel 411 is coaxially opened in the connecting pin 41, two symmetrical air outlets 412 are penetrated on the side wall of the connecting pin 41, two symmetrical mounting blocks 413 are fixed on the side wall of the connecting pin 41, two symmetrical mounting holes 202 are penetrated on the side wall of the connecting seat 20, and the two mounting blocks 413 slide up and down in the corresponding mounting holes 202 respectively, the material of the connecting seat 20 is transparent PC, which is a high-performance thermoplastic engineering plastic, and the connecting pin 41 and the suspension seat 40 are made of transparent PC, which is a high-performance thermoplastic engineering plastic. The material can also be transparent PC. Two symmetrical air inlets 203 are formed on the side wall of the connecting seat 20. The air inlet 203 matches the air outlet 412. The connecting pin 41, the mounting hole 202 and the mounting block 413 are arranged. Under normal circumstances, the mounting block 413 is located at the bottom of the mounting block 413 under the action of gravity. The gas passes through the air inlet channel 411, the air outlet 412, the air inlet 203 and the air outlet channel 201 in turn, and is finally ejected from the air outlet pipe 112. When cleaning or replacing the filter element 30, the collection barrel 12 is first unscrewed, and then the suspension seat 40 is pulled out to one side. At this time, the connecting pin 41 drives the connecting seat 20 to detach from the connecting cylinder 13, and the filter element 30 slides out from the inside of the connecting cylinder 13, so that the filter element 30 can be quickly replaced.

[0031] In order to enhance the sealing between the connecting pin 41 and the connecting seat 20, a sealing rubber ring 50 is coaxially fixed on the top of the connecting pin 41;

[0032] Taking into account that the collection barrel 12 may be full during use, it is easy to cause damage to the filter itself if there is no full-fill warning. The interior of the suspension seat 40 is bonded with an identification piece 60, and the interior of the connecting cover 11 is fixed with a mounting tube 15, and the mounting tube 15 is located on one side of the connecting tube 13. The interior of the mounting tube 15 is coaxially provided with a proximity switch 70. Through the settings of the suspension seat 40, the identification piece 60 and the proximity switch 70, when the wastewater or colloid in the collection barrel 12 is about to be full, the suspension seat 40 moves upward with the change of the liquid level until the identification piece 60 contacts the proximity switch 70. At this time, the proximity switch 70 sends a full-fill warning to the external control box through the signal line, reminding the user to replace the collection barrel 12, thereby improving the service life of the equipment.

[0033] In order to facilitate the sealing and installation of the connecting cover 11 and the collecting barrel 12, the connecting cover 11 and the collecting barrel 12 are connected by threads. In this embodiment, the double-headed threads provided on the connecting cover 11 and the collecting barrel 12 only need to be rotated a certain angle to achieve a fixing effect.

[0034] refer to Figure 3 , Figure 7 As shown, in order to facilitate the proximity switch 70 to send out a warning signal, a wiring cavity 113 is opened on the top of the connection cover 11, and lead tubes 80 are fixed on both sides of the air outlet pipe 112. The installation tube 15 is connected to the wiring cavity 113, and spring pins 81 are coaxially fixed in the two lead tubes 80. The positive and negative signal lines on the proximity switch 70 are respectively connected to the corresponding spring pins 81. The other end of the spring pin 81 is externally connected to a control box. A control module is arranged inside the control box. After the control box receives the warning signal sent by the proximity switch 70, it can remind the user by flashing a signal light or beeping a buzzer.

[0035] refer to Figure 4 and Figure 6 As shown, in order to facilitate the suspension seat 40 to slide up and down in the connection cover 11, the suspension seat 40 is provided with an arc groove 401 matching with the air intake cylinder 14.

[0036] refer to Figure 1 and Figure 3 As shown, in order to protect the wiring cavity 113 and prevent external interference from damaging the signal line, a top cover 90 is threadedly connected to the top of the connection cover 11 , and the top cover 90 is located above the wiring cavity 113 .

[0037] When the utility model is used:

[0038] First, connect the air inlet pipe 111 and the air outlet pipe 112 to the corresponding external devices respectively. The air outlet pipe 112 can be connected to the beauty equipment at the rear end, and the air inlet pipe 111 can be connected to the air pump;

[0039] Then, the gas enters the shell 10 through the air inlet pipe 111. When initially entering the shell 10, the gas is guided by the air inlet cylinder 14 into the collecting barrel 12 below. The sewage or colloid carried in the gas is mainly gathered in the collecting barrel 12, and then passes through the air inlet channel 411, the air outlet 412, the air inlet 203 and the air outlet channel 201 in sequence, and finally ejected from the air outlet pipe 112.

[0040] Secondly, when the wastewater or colloid in the collection barrel 12 is about to be filled, the suspension seat 40 moves upward with the change of the liquid level until the identification piece 60 contacts the proximity switch 70, and the proximity switch 70 sends a full-fill warning to the external control box through the signal line;

[0041] Finally, when cleaning or replacing the filter element 30, first unscrew the collection barrel 12, then hold the suspension seat 40 and pull it out to one side. At this time, the connecting pin 41 drives the connecting seat 20 to detach from the connecting tube 13, and the filter element 30 slides out from the inside of the connecting tube 13. Take out the new filter element 30 and put it into the inside of the connecting tube 13, and then snap the connecting seat 20 into the inside of the connecting tube 13.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
