[0002] The use of flavors and fragrances in daily life is increasing. They can give flavor to food ingredients, correct bad odors in food, supplement the lack of aroma in food, stabilize and assist the inherent aroma in food, and correct the uncomfortable odors in daily chemical products, produce pleasant odors, and improve product grades. At present, in the production process of flavors and fragrances, conveying pumps are used for transportation. However, during the transportation process, some impurity particles may be mixed in the flavors and fragrances. Directly using a conveying pump for transportation may damage the conveying pump.

[0003] Patent No. CN 216395443 U discloses a filtering device for a flavor and fragrance delivery pump. The provided filtering mechanism makes it easier for people to clean the residue on the filter plate, effectively prevents the residue from clogging the mesh, and further improves the filtering effect of the filter plate. When cleaning the residue, the cylinder is started, and the cylinder drives the soft scraper to move up and down through the piston rod. The soft scraper is located between the second filter plate and the first filter plate. After the soft scraper moves up and down, it scrapes the residue from the two sets of filter plates and scrapes the residue off the filter plates. The cover plate is removed from the filter box, and the scraped residue can be cleaned. The mesh diameter of the second filter plate is smaller than that of the first filter plate, and smaller residue can be filtered. The material of the soft scraper is softer to prevent scratching the filter plate.

[0004] However, in use, there are the following defects:

[0005] Although a soft scraper is used to scrape the two filter plates simultaneously, the dust attached to the surface of the front filter plate that is hit by the material cannot be scraped off during the scraping process, resulting in limited cleaning effect. In addition, the scraped dust will fall freely, making it inconvenient to collect. Utility Model Content

[0006] The purpose of the utility model is to provide a filtering device for an essence and fragrance delivery pump, which solves the problem proposed in the background art that during the simultaneous scraping of two filter plates, the dust attached to the surface of the side of the filter plate located in the front side that is impacted by the material cannot be scraped off, resulting in limited cleaning effect, and the scraped dust will fall freely, making it inconvenient to collect.

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0024] A filter device for a flavor and fragrance delivery pump, see Figures 1 to 4, including a filter box 1, a filter frame 2, a top plate 101 and a hose 5, the front and rear inner walls of the filter box 1 are provided with slots 104, the top of the top plate 101 is provided with a pull-out slot 204, the filter frame 2 is vertically slidably connected inside the pull-out slot 204 and the slot 104, and the inner side of the filter frame 2 is fixedly connected with two left and right filter screens 201, and a discharge pipe 103 is provided on the side wall of the filter box 1 between the two filter screens 201; the outer side walls of the filter box 1 on both sides of the discharge pipe 103 are fixedly connected with electric push rods 3, and the telescopic end of the electric push rod 3 passes through the filter box 1 The outer wall of the adsorption box 1 is fixedly connected to the adsorption frame 4 on the inner side of the filter box 1, the adsorption opening of the adsorption frame 4 faces the side of the filter screen 201, and a scraper 8 is fixedly connected to the adsorption opening of the adsorption frame 4. The adsorption frame 4 and the vacuum cleaner 6 located outside the filter box 1 are connected through a hose 5. The electric push rod 3 is started, driving the adsorption frame 4 at the telescopic end to move horizontally. During the movement, the scraper 8 on the adsorption frame 4 will scrape the surface of the filter screen 201, and the scraped dust particles will be sucked away by the vacuum cleaner 6 at the first time to prevent them from floating freely, which facilitates the collection of dust particles.

[0025] During the inhalation process, the cover of the air outlet 105 on the top plate 101 can be opened to allow the air pressure in the filter box 1 to be normal. A filtering net can be set on the inside of the air outlet 105 to prevent new dust from the outside from entering the filter box 1.

[0026] Specifically, such as Figure 4 As shown, the edge of the surface of the adsorption frame 4 facing the filter 201 is fixedly connected with a rubber strip 7. The rubber strip 7 does not contact the surface of the filter 201 and the gap is small. The rubber strip 7 can cover the edge of the adsorption frame 4 as much as possible so that the scraped dust particles can be directly sucked away. The reason for the gap is to avoid touching the filter 201 and causing the dust to be scraped off in advance by the rubber strip 7 and fall to the outside of the adsorption frame 4 and be difficult to be sucked away.

[0027] It is worth noting that the scraper bar 8 is in contact with the surface of the filter 201, and the length of the scraper bar 8 exceeds the height of the filter 201, so the scraper bar 8 can completely cover the surface of the filter 201, avoiding dead corners when scraping and resulting in low scraping efficiency.

[0028] It is worth noting that if Figure 1 and Figure 2 As shown, a feed pipe 102 is provided on the outer wall of the filter box 1 opposite to the discharge pipe 103. The feed pipe 102 has two inlets and is respectively located on the left and right sides of the filter frame 2, so that the area in the center of the two filter screens 201 is the discharge area.

[0029] It is worth noting that there is a certain distance between the upper and lower surfaces of the adsorption frame 4 and the bottom of the top plate 101 and the bottom of the filter box 1, so as to avoid scraping the top plate 101 and the filter box 1 during movement, and the adsorption frame 4 and the inner bottom surface of the filter box 1 are perpendicular to each other, which can better cooperate with the scraper 8 to cover the filter screen 201.

[0030] It is worth noting that if Figure 1 and Figure 3 As shown, a handle 202 is fixedly connected to the top of the filter frame 2, and a fixing bolt 203 is threadedly connected to the center of the top of the filter frame 2 on one side of the handle 202. The bottom end of the fixing bolt 203 passes through the surface of the filter frame 2 and is threadedly connected to the top plate 101. The handle 202 makes it convenient for the staff to lift or insert the filter frame 2, and the fixing bolt 203 can fix the filter frame 2 tightly on the top plate 101 after being tightened, thereby increasing stability.

[0031] During actual use, the material enters the inner side of the filter box 1 through the feed pipe 102, and the dust particles are intercepted under the filtration of the filter screen 201, and the filtered material leaves the discharge pipe 103. In this process, after the vacuum cleaner 6 is started, the inner side of the filter box 1 is sucked along the hose 5 and the adsorption frame 4, and the electric push rod 3 is started, driving the adsorption frame 4 at the telescopic end to move horizontally. During the movement, the scraping bar 8 on the adsorption frame 4 will scrape the surface of the filter screen 201, and the scraped dust particles will be sucked away by the vacuum cleaner 6 at the first time to prevent them from floating freely, which facilitates the collection of dust particles and improves the practicality of the device; the filter frame 2 is directly inserted into the pull-out slot 204 and the slot 104, so when it needs to be disassembled, you only need to directly lift or insert the filter frame 2 without removing the top plate 101. It has a simple structure, convenient operation and strong practicality.

[0032] In addition, the components designed in this utility model are all universal standard parts or components known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. They can be fully implemented by technical personnel in this field. Needless to say, the content protected by this utility model does not involve improvements to internal structures and methods.
