Description

Technical Field

[0001] The present invention relates to the technical field of decontamination and cleaning, and particularly to a cleaning device for valve accessories. Background Art

[0002] Valve accessories usually include metal parts such as valve stems, valve cores, valve seats, gland nuts, etc. During the processing process, metal chips, oil stains, dust and other sundries will remain on the surface of the valve accessories. If these sundries are not removed, they will affect the sealing performance, transmission accuracy and service life of the valves. Therefore, after the valve accessories are processed, they are generally cleaned with an ultrasonic cleaning machine. The ultrasonic cleaning machine can generate high-frequency vibrations, forming countless tiny bubbles in the cleaning liquid. When these bubbles burst, they will generate a strong impact force, shaking off and cleaning the sundries on the surface of the valve accessories.

[0003] Generally, batches of valve accessories are placed in a cleaning basket for cleaning. However, when the valve accessories are stacked, the cleaning effect will be poor. For this reason, the utility model patent with the authorization announcement number CN221657386U discloses an ultrasonic decontamination device, which includes an ultrasonic cleaning machine main body, a base fixed at the bottom of the ultrasonic cleaning machine main body, a lifting device arranged on the base, and a metal part placement device arranged inside the ultrasonic cleaning machine main body. The lifting device is connected to the metal part placement device, and the lifting device drives the metal part placement device to lift and lower. Among them, the metal part placement device includes a grid cage that can be placed inside the ultrasonic cleaning machine main body. Inside the grid cage, a first grid plate and a second grid plate are arranged in the up-and-down distribution. When in use, both the first grid plate and the second grid plate are used to place metal parts, thereby realizing the layered placement of metal parts.

[0004] In the prior art, the cleaning effect can be improved by placing the metal parts in layers. However, when applied to the cleaning of valve accessories, since there is oil stain remaining on the surface of the valve accessories, after cleaning, the oil stain floats on the surface of the cleaning liquid. When the valve accessories are taken out upwards, the oil stain on the surface of the cleaning liquid will adhere to the surface of the valve accessories again, causing secondary pollution. Summary of the Invention

[0005] The present invention provides a cleaning device for valve accessories to solve the technical problem of secondary pollution caused by the easy adhesion of the oil stain on the surface of the cleaning liquid when the valve accessories are taken out upwards in the prior art.

[0006] To solve the above problems, the valve accessory cleaning device provided by the present invention adopts the following technical solutions: The valve accessory cleaning device includes an ultrasonic cleaning machine and a carrying module that moves down and up during ultrasonic cleaning. The carrying module includes an outer cylinder, a discharge port sealing plate, and a limiting block, an inner carrying cylinder, and a material receiving mesh plate located inside the outer cylinder. One side of the bottom of the outer cylinder is provided with a discharge port corresponding to the material receiving mesh plate, and the discharge port sealing plate is installed on the outer cylinder to close the discharge port; there are two limiting blocks arranged at intervals left and right. The two limiting blocks are fixed on the outer cylinder and are respectively in contact with the left and right inner walls of the outer cylinder. Arc surfaces are provided on the opposite sides of the two limiting blocks, and the two arc surfaces are located on the same circular trajectory. The inner carrying cylinder is rotatably assembled between the arc surfaces of the two limiting blocks in a manner adapted to the axis extending in the front and rear directions. The front and rear ends of the limiting block and the inner carrying cylinder are in contact with the inner wall of the outer cylinder; the outer cylinder and the discharge port sealing plate enclose an installation space that is closed all around. The top of the installation space extends to the top surface of the limiting block, and the bottom extends below the material receiving mesh plate;

[0007] The inner carrying cylinder includes a C-shaped cylinder body with an opening on one side and a support mesh plate. The C-shaped cylinder body includes a closed section opposite to the opening and mesh sections provided on both sides of the closed section. One end of the support mesh plate is fixedly provided inside the closed section and the other end extends towards the opening. When the inner carrying cylinder rotates, it has a feeding position with the opening facing upwards, a cleaning position with the support mesh plate arranged horizontally, and a closed position with the opening facing downwards and the closed section closing the channel between the two limiting blocks to close the top opening of the installation space.

[0008] During use, first rotate the inner carrying cylinder to the feeding position, put the valve accessories into the inner carrying cylinder, and then rotate the inner carrying cylinder to the cleaning position. During the rotation process, the support mesh plate gradually rotates to the horizontal state, so that the valve accessories are supported on the support mesh plate. Through the support mesh plate, the internal space of the inner carrying cylinder can be stratified, realizing stratified cleaning and improving the cleaning effect. After cleaning, rotate the inner carrying cylinder to the closed position, and the closed section closes the channel between the two limiting blocks, and the valve accessories fall on the support mesh plate. In the present invention, since the outer cylinder and the discharge port sealing plate together form an installation space that is closed all around, the ends of the inner carrying cylinder and the limiting block are in contact with the inner side of the outer cylinder, and the valve accessories on the support mesh plate are located in the installation space. When the inner carrying cylinder is in the closed position, the closed section and the two limiting blocks close the top opening of the installation space. During the process of lifting the carrying module, the oil stain directly above the carrying module will fall on the outer sides of the tops of the limiting block and the closed section. The oil stain between the carrying module and the ultrasonic cleaning machine is always located outside the outer cylinder and the discharge port sealing plate, and the oil stain on the surface of the cleaning liquid cannot enter the interior of the installation space, ensuring that the valve accessories will not be secondarily polluted.

[0009] As a further improvement, at least two support mesh plates are arranged, and the at least two support mesh plates are arranged in parallel. The end of each support mesh plate away from the closed section is located in the circumferential locus. A placement space for placing valve fittings is formed between two adjacent support mesh plates and between the support mesh plate and the mesh hole section.

[0010] As a further improvement, oil stain through holes are provided on the left and right sides at the top of the outer cylinder, and the bottom edge of the oil stain through hole is arranged flush with the limiting block; the oil stain through hole is used for discharging the oil stain on the limiting block and the top of the closed section when the bearing module is lifted.

[0011] As a further improvement, the top surface of the limiting block is arranged to be inclined downward and towards the oil stain through hole. The inclined arrangement of the top surface of the limiting block is beneficial to the automatic flow of the oil stain towards the oil stain through hole.

[0012] As a further improvement, the inner bearing cylinder is rotationally assembled on the outer cylinder through a rotating shaft penetrating the outer cylinder. The valve fitting cleaning device includes a driving mechanism for driving the inner bearing cylinder to rotate. The driving mechanism includes a gear and a sliding seat fixed on the rotating shaft and located outside the outer cylinder. The sliding seat is slidably assembled on the ultrasonic cleaner in the left-right direction. The sliding seat includes a vertical plate located inside the ultrasonic cleaner. A groove for the gear to enter is provided on the vertical plate. First racks and second racks are respectively provided on the opposite two groove walls of the groove. The first rack is located above the second rack; when the sliding seat slides, it has a first position where the first rack meshes with the lowered gear and a second position where the second rack meshes with the lifted gear. When lowering, the gear and the inner bearing cylinder are driven to rotate in one direction through the meshing of the first rack and the gear, so as to rotate from the placement position to the cleaning position; when lifting, the gear and the inner bearing cylinder are driven to continue rotating in this direction through the meshing of the second rack and the gear, so as to rotate from the cleaning position to the closed position, and then gradually separate from the cleaning liquid. On the one hand, through the meshing of the gear and the rack, manual rotation is not required; on the other hand, no additional power source needs to be equipped, saving costs.

[0013] As a further improvement, a receiving groove for receiving the vertical plate is provided inside the ultrasonic cleaner.

[0014] As a further improvement, two gears are symmetrically arranged, and one of the two gears is used for meshing with the first rack and the second rack.

[0015] As a further improvement, the material receiving screen plate is arranged obliquely downward and towards the discharge port. The material receiving screen plate includes a first screen plate installed on the outer cylinder, a second screen plate telescopically assembled on the first screen plate, and a screen plate spring for driving the second screen plate away from the first screen plate. A support plate is provided at the inner bottom of the discharge port seal plate, and the end of the second screen plate facing away from the first screen plate is supported on the support plate. The screen plate spring ensures that the second screen plate is always supported on the support plate, and the overall support screen plate is arranged obliquely, so that the valve fittings automatically slide towards the discharge port.

[0016] As a further improvement, the bearing module includes a filter screen plate located below the material receiving screen plate. The filter screen plate is used to filter out the sundries washed away. A waste discharge port is opened on the outer cylinder, and a waste box is installed in the waste discharge port. The waste box is used to collect the sundries on the filter screen plate.

[0017] As a further improvement, the outer cylinder includes a top frame at the top, a bottom frame at the bottom, and a connecting spring connecting the top frame and the bottom frame. The top of the bottom frame is telescopically assembled in the top frame and is in sealing cooperation with the top frame. The material receiving screen plate and the filter screen plate are both arranged in the bottom frame. Oblique grooves are provided on the left and right inner sides of the bottom of the top frame. The oblique grooves are inclined downward and towards the waste discharge port;

[0018] The bearing module further includes a scraper extending in the left-right direction. Square pins are provided at both ends of the scraper. The square pins penetrate through the bottom frame and are fitted into the oblique grooves. When the bottom frame slides downward, the scraper is driven to move through the oblique grooves and the square pins to scrape the sundries on the filter screen plate into the waste box. After the oblique grooves and the square pins are provided, by using the characteristic that the bottom frame will float downward after the valve fittings fall on the support screen plate, the scraper is driven to move to scrape off the sundries, which is more convenient to use.

[0019] The beneficial effects are:

[0020] 1. During use, first rotate the inner loading cylinder to the feeding position, place the valve fitting into the inner loading cylinder, and then rotate the inner loading cylinder to the cleaning position. During the rotation process, the support mesh plate gradually rotates to a horizontal state, enabling the valve fitting to be supported on the support mesh plate. Through the support mesh plate, the internal space of the inner loading cylinder can be stratified, achieving stratified cleaning and improving the cleaning effect. After cleaning, rotate the inner loading cylinder to the closed position. The closed section closes the channel between the two limit blocks, and the valve fitting falls on the support mesh plate. In the present invention, since the outer cylinder and the discharge port sealing plate together form a closed installation space all around, the ends of the inner loading cylinder and the limit blocks are in contact with the inner side of the outer cylinder, and the valve fitting on the support mesh plate is located in the installation space. When the inner loading cylinder is in the closed position, the closed section and the two limit blocks close the top opening of the installation space. During the process of lifting the loading module, the oil stain directly above the loading module will fall on the outer sides of the tops of the limit blocks and the closed section. The oil stain between the loading module and the ultrasonic cleaning machine is always located outside the outer cylinder and the discharge port sealing plate, and the oil stain on the surface of the cleaning liquid cannot enter the interior of the installation space, ensuring that the valve fitting will not be re - contaminated.

[0021] 2. The top surface of the limit block is inclined, which is beneficial for the automatic flow of oil stain towards the oil stain through - hole.

[0022] 3. When lowering, through the meshing of the first rack and the gear, the gear and the inner loading cylinder are driven to rotate in one direction, so as to rotate from the placement position to the cleaning position; when lifting, through the meshing of the second rack and the gear, the gear and the inner loading cylinder are driven to continue rotating in this direction, so as to rotate from the cleaning position to the closed position, and then gradually separate from the cleaning liquid. On the one hand, through the meshing of the gear and the rack, there is no need for manual rotation; on the other hand, there is no need to be equipped with an additional power source, saving costs.

[0023] 4. The mesh plate spring ensures that the second mesh plate is always supported on the support plate, and the overall support mesh plate is inclined, enabling the valve fitting to slide automatically towards the discharge port.

[0024] 5. After setting the inclined groove and the square pin shaft, by utilizing the characteristic that the bottom frame will float downward when the valve fitting falls on the support mesh plate, the scraper is driven to move to scrape off debris, making it more convenient to use.

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0052] Embodiment of the valve accessory cleaning device provided by the present invention:

[0053] As Figures 1 to 22As shown in the figure, the valve fitting cleaning device includes an ultrasonic cleaning machine 100, a carrying module 200 for carrying valve fittings, and a driving mechanism 300. The carrying module 200 can be lowered into the ultrasonic cleaning machine 100 and can also be lifted upward from the ultrasonic cleaning machine 100.

[0054] As Figures 1 to 7 shown, the ultrasonic cleaning machine 100 includes a housing 101, a control panel 102 on the front side of the housing 101, and an ultrasonic generator. The housing 101 is used to hold the cleaning liquid. The top of the housing 101 is open for the workpiece carrying module 200 to be lowered and lifted. Drain ports 103 are respectively provided on the left and right sides of the top of the housing 101. The drain ports 103 are used to drain oil stains. Slide plates 104 that slope downward are installed on both the left and right sides of the housing 101, and the oil stains drain downward along the slide plates 104. The ultrasonic generator is usually installed at the bottom of the housing 101. The working principle and installation method of the ultrasonic generator are prior art and will not be elaborated here.

[0055] Receiving grooves 105 are respectively provided at the middle positions on the inner sides of the housing 101 in the front-back direction. The receiving grooves 105 extend vertically and are used to receive the driving mechanism 300. Guide holes 106 are provided on both the front and back sides of the housing 101. The guide holes 106 penetrate the housing 101 in the front-back direction and are communicated with the receiving grooves 105.

[0056] As Figures 1 to 5 and Figures 8 to 18 shown, the carrying module 200 includes an outer cylinder 201, a limit block 202, an inner carrying cylinder 203, a material receiving mesh plate 204, a discharge port sealing plate 205, a filter mesh plate 206, a scraper 207, and a debris box 208.

[0057] The outer cylinder 201 includes a top frame 209, a bottom frame 210, and a connecting spring 215. Both the top frame 209 and the bottom frame 210 are structures that are open at the top and bottom. The top end of the bottom frame 210 is inserted upward into the top frame 209, and the bottom frame 210 can slide up and down, but the top end of the bottom frame 210 is always located inside the top frame 209. The top end of the bottom frame 210 is in contact with the top frame 209. In actual use, a ring groove can be provided inside the top frame 209 and a sealing member can be arranged to achieve the sealing between the bottom frame 210 and the top frame 209, preventing the cleaning liquid from entering the outer cylinder 201 through the connection position between the top frame 209 and the bottom frame 210.

[0058] The top enclosure 209 is formed by enclosing with four side plates on the left, right, front, and rear. Among them, oil pollution through-holes 211 are provided at the tops of the left side plate and the right side plate, allowing oil pollution to enter the sewage outlet 103 of the outer cylinder 201 after passing through. The bottom surfaces of the left side plate and the right side plate are located below the bottom surfaces of the front side plate and the rear side plate. Oblique grooves 212 are provided inside the bottoms of the left side plate and the right side plate, and the inclined direction of the oblique grooves 212 is from front to back and extends downward. Handles 213 are installed at the tops of the left side plate and the right side plate for the staff to hold, so as to lift and lower the carrying module 200. Coaxial rotation shaft through-holes 236 are provided on both the front side plate and the rear side plate.

[0059] The bottom enclosure 210 includes guide posts 214 at the four corners of the top. The guide posts 214 extend up and down, and openings are provided at the tops of the guide posts 214. The connecting springs 215 are fixedly installed in the openings at the tops of the guide posts 214. Here, the connecting springs 215 are tension springs.

[0060] Coaxial hinge shaft through-holes 216 are provided at the front ends of the left and right sides of the bottom enclosure 210. Pin shaft through-holes 217 are also provided on the left and right sides of the bottom enclosure 210. The pin shaft through-holes 217 extend in the front-back direction and are located below the hinge shaft through-holes 216.

[0061] An outlet 218 and a waste discharge port 219 are provided at the rear of the bottom enclosure 210. The outlet 218 is used to discharge the cleaned valve fittings, and the waste discharge port 219 is used to discharge the cleaned debris. The outlet 218 is located above the waste discharge port 219.

[0062] There are two limit blocks 202, which are respectively fixed inside the left side plate and the right side plate of the top enclosure 209. Specifically, welding or countersunk head bolts can be used for fixation. The structures of the two limit blocks 202 are the same, and the two limit blocks 202 are arranged at intervals in the left-right direction. The limit blocks 202 are in contact with the left side plate and the right side plate, and the front and rear end faces of the limit blocks 202 are in contact with the front side plate and the rear side plate in the top enclosure 209. An arc surface 220 is provided on the opposite side of the limit blocks 202. The arc surface 220 of the left limit block 202 is recessed to the left, and the arc surface 220 of the right limit block 202 is recessed to the right. The arc surfaces 220 of the two limit blocks 202 are arranged oppositely, and the two arc surfaces 220 are located on the circumferential track of the same circle.

[0063] The limit blocks 202 have an inclined top surface 221. The inclined direction of the top surface 221 is from top to bottom and inclined towards the side plate on the corresponding side, that is, the top surface 221 of the left limit block 202 is inclined from top to bottom and towards the left, and the top surface 221 of the right limit block 202 is inclined from top to bottom and towards the right. The edge of the limit block 202 close to the top enclosure 209 is flush with the bottom hole edge of the oil pollution through-hole 211.

[0064] At the bottom vertex positions of the two limit blocks 202, guide grooves 222 are formed for the guide posts 214 to be adaptively inserted in the up and down directions. The upper end of the connecting spring 215 is connected in the guide groove 222. The connecting spring 215 applies an upward elastic pulling force to the bottom surrounding frame 210. When the bottom surrounding frame 210 is subjected to a downward acting force, the connecting spring 215 is pulled downward.

[0065] The inner bearing cylinder 203 is rotatably and adaptively installed between the two limit blocks 202 around an axis extending in the front and rear directions. Here, the adaptation means that the outer peripheral surface of the inner bearing cylinder 203 is located in the circumferential trajectory where the arc surfaces 220 of the two limit blocks 202 are located. During actual processing, there is usually a clearance fit between the outer periphery of the inner bearing cylinder 203 and the arc surfaces 220 of the limit blocks 202 to ensure that the inner bearing cylinder 203 can rotate smoothly. The front and rear end faces of the inner bearing cylinder 203 are respectively in contact with the front side plate and the rear side plate of the top surrounding frame 209.

[0066] The inner bearing cylinder 203 includes a C-shaped cylinder body 223, a support mesh plate, and a rotating shaft 224. Among them, the outer peripheral surface of the C-shaped cylinder body 223 is located in the circumferential trajectory where the arc surface 220 is located. One side of the C-shaped cylinder body 223 is open to form a C-shaped structure. The C-shaped cylinder body 223 includes a closed section 225 and two mesh sections 226. The outer peripheral surface of the closed section 225 is closed, and the closed section 225 faces the opening of the C-shaped cylinder body 223. The inner side of the closed section 225 is a plane, which is convenient for installing the support mesh plate; mesh holes are formed on the mesh sections 226 for the cleaning liquid to pass through, and the two mesh sections 226 are located on both sides of the closed section 225.

[0067] There are five support mesh plates here. The five support mesh plates are vertically fixed on the inner side plane of the closed section 225. The spacing arrangement direction of the five support mesh plates is the same as the spacing arrangement direction of the two mesh sections 226. One end of the support mesh plate is fixed on the closed section 225, and the other end extends towards the opening of the C-shaped cylinder body 223.

[0068] Here, for convenience of description, five supporting mesh plates are defined, namely the first supporting mesh plate 227 located in the middle, two second supporting mesh plates 228 located on both sides of the first supporting mesh plate 227, and a third supporting mesh plate 229 located between the second supporting mesh plate 228 and the mesh section 226. The length of the first supporting mesh plate 227 is greater than that of the second supporting mesh plate 228, and the length of the second supporting mesh plate 228 is greater than that of the third supporting mesh plate 229. The distance between the two second supporting mesh plates 228 is less than the distance between the top surfaces of the two limiting blocks 202, so that the staff can place the valve fittings into the space between the second supporting mesh plate 228 and the third supporting mesh plate 229. The ends of the first supporting mesh plate 227, the second supporting mesh plate 228, and the third supporting mesh plate 229 are located on the circumferential locus of the outer peripheral surface of the C-shaped cylinder 223. The third supporting mesh plate 229 connects the closed section 225 and the mesh section 226. The first supporting mesh plate 227, the second supporting mesh plate 228, and the third supporting mesh plate 229 are all provided with mesh holes for the cleaning liquid to pass through.

[0069] There are two rotating shafts 224, which are respectively fixed on the front and rear sides of the first supporting mesh plate 227, and the two rotating shafts 224 are coaxially arranged. The rotating shaft 224 is used to penetrate into the rotating shaft through hole 236 of the top frame 209, and the rotating shaft 224 and the rotating shaft through hole 236 are in sealed cooperation, which can be specifically realized by setting a sealing ring.

[0070] The material receiving mesh plate 204 is located in the bottom frame 210 and is inclined as a whole. The material receiving mesh plate 204 includes a hinge shaft 230, a first mesh plate 231, a second mesh plate 232, and a mesh plate spring 233. The two ends of the hinge shaft 230 are inserted into the hinge shaft through holes 216 of the bottom frame 210. One end of the first mesh plate 231 is fixed on the hinge shaft 230. The second mesh plate 232 is telescopically assembled at the other end of the first mesh plate 231. The mesh plate spring 233 is fixed between the first mesh plate 231 and the second mesh plate 232. The mesh plate spring 233 here is a compression spring, which can apply force to the second mesh plate 232 to make the second mesh plate 232 extend out of the first mesh plate 231.

[0071] Wherein, the first mesh plate 231 and the second mesh plate 232 are both provided with mesh holes, and the mesh holes on the first mesh plate 231 and the second mesh plate 232 can allow sundries and cleaning liquid to pass through but the valve fittings cannot pass through.

[0072] The discharge port sealing plate 205 is used to seal the discharge port 218. A support plate 234 is fixed to the inner bottom of the discharge port sealing plate 205. One end of the second net plate 232 abuts against the inner side of the discharge port sealing plate 205 and is supported on the support plate 234. When the discharge port sealing plate 205 is pulled outwards, the second net plate 232 remains supported on the support plate 234 under the action of the net plate spring 233. Among them, in order to ensure that the discharge port sealing plate 205 keeps the discharge port 218 sealed before the valve fittings are taken out, bolts can be provided on the discharge port sealing plate 205 to fix the discharge port sealing plate 205 to the bottom frame 210 with bolts.

[0073] The filter net plate 206 is fixed inside the bottom frame 210. The filter net plate 206 is located below the material receiving net plate 204. The filter net plate 206 is provided with mesh holes, and the mesh holes of the filter net plate 206 allow the cleaning liquid to pass through and intercept sundries. There is a gap between the rear end of the filter net plate 206 and the rear inner wall of the bottom frame 210.

[0074] The scraper 207 is slidably assembled in the bottom frame 210 in the front-back direction. Specifically, square pin shafts 235 are fixedly installed at both the left and right ends of the scraper 207. The square pin shafts 235 pass through the pin holes 217 and are adaptively inserted into the inclined slots 212 of the top frame 209, so that the scraper 207 can only slide in the front-back direction and will not rotate. The bottom of the scraper 207 contacts the top surface of the filter net plate 206 or has only a small distance, so that when the scraper 207 moves backward, it can scrape off the sundries on the filter net plate 206.

[0075] The sundries box 208 is installed in the impurity discharge port 219 in a pull-out manner. The scraper 207 can scrape the sundries on the filter net plate 206 into the sundries box 208, and the sundries box 208 can collect the sundries.

[0076] In the present invention, the outer cylinder 201 and the discharge port sealing plate 205 enclose an installation space that is closed on all four sides. The top of the installation space extends to the top surface of the limit block 202, specifically, the bottom hole edge of the oil stain through hole 211; the bottom of the installation space extends below the material receiving net plate 204, specifically, the bottom of the discharge port sealing plate 205. The top opening of the installation space is the passage between the two limit blocks 202.

[0077] The function of the driving mechanism 300 is to drive the inner bearing cylinder 203 to rotate. When the closed section 225 of the inner bearing cylinder 203 is below, valve fittings to be cleaned can be placed between two adjacent support net plates and between the third support net plate 229 and the mesh section 226. At this time, the inner bearing cylinder 203 is in the feeding position, as Figure 14 shown. When each support net plate is in a horizontal state, the valve fittings are laid flat on each support net plate, and the cleaning liquid cleans the valve fittings. At this time, the inner bearing cylinder 203 is in the cleaning position, as Figure 15As shown. When the closed section 225 of the inner carrier cylinder 203 is above, the closed section 225 seals the passage between the two limit blocks 202, closing the top opening of the above installation space. At this time, the inner carrier cylinder 203 is in the closed position, as Figure 16 shown.

[0078] As Figures 1 to 5 and Figures 19 to 22 shown, the drive mechanism 300 includes a sliding seat, a handle 304, a tightening bolt 305, a first rack 306, a second rack 307, and a gear 308. The sliding seat is slidably assembled on the outer shell 101 in the front-rear direction. Specifically, the sliding seat includes a vertical plate 301 and a horizontal plate 302 fixed to the top of the vertical plate 301. The vertical plate 301 is located in the receiving groove 105 of the outer shell 101, and the horizontal plate 302 passes through the guiding hole 106 of the outer shell 101 and can move left and right in the guiding hole 106. A groove 303 is formed on one side of the vertical plate 301 facing the bearing module 200. A first rack 306 is formed on one side wall of the groove 303, and a second rack 307 is formed on the other side wall. The first rack 306 is located above the second rack 307.

[0079] The handle 304 is fixed to the horizontal plate 302 and is located outside the outer shell 101. Here, the handle 304 is a plate body. There are two tightening bolts 305. The two tightening bolts 305 are threadedly assembled on both sides of the handle 304. After the sliding seat moves into place, by rotating the tightening bolts 305, the tightening bolts 305 press against the outer side surface of the outer shell 101, thereby fixing the position of the sliding seat.

[0080] There are two gears 308. The two gears 308 are respectively fixed on the rotating shaft 224, and the gears 308 are located outside the outer cylinder 201.

[0081] During the use process: In the initial state, the inner carrier cylinder 203 is in the feeding position. Move the sliding seat toward the side where the second rack 307 is located. At this time, the sliding seat is in the first position, as Figure 21 shown, and place the valve fitting into the inner carrier cylinder 203.

[0082] Lower the bearing module 200 into the ultrasonic cleaner 100. During the lowering process, the gear 308 meshes with the first rack 306, and the inner carrier cylinder 203 rotates while being lowered. After being lowered in place, each support mesh plate is horizontally arranged, and the valve fittings are laid flat on the support mesh plates (it should be noted that if the support mesh plates are not horizontally arranged after being lowered in place, the inner carrier cylinder 203 can be manually rotated for leveling). Subsequently, the ultrasonic cleaner 100 starts to work to clean the valve fittings.

[0083] After the cleaning is completed, move the sliding seat toward the side where the first rack 306 is located. At this time, the sliding seat is in the second position, as Figure 22As shown in the figure, when lifting the loading module 200, before the loading module 200 reaches the cleaning liquid surface, the gear 308 meshes with the first rack 306, causing the inner loading cylinder 203 to rotate to the closed position, and the closed section 225 and the limiting block 202 together close the top of the loading module 200. At this time, the valve fitting falls on the material receiving mesh plate 204, and the sundries fall on the filter mesh plate 206 after passing through the material receiving mesh plate 204. The bottom frame 210 slides downward under the action of gravity. During the sliding process, the square pin shaft 235 slides in the inclined slot 212, driving the scraper 207 to slide, and scraping the sundries on the filter mesh plate 206 into the sundries box 208.

[0084] During the process of lifting the loading module 200, the top of the loading module 200 is closed, and the outer cylinder 201 and the discharge port sealing plate 205 enclose an installation space that is closed at the top and around. The valve fitting is in the installation space, and the oil stain will not cause secondary pollution to the valve fitting.

[0085] During the process of lifting the loading module 200, the oil stains on the outer sides of the tops of the inner loading cylinder 203 and the limiting block 202 are carried upward and discharged outside the housing 101 through the oil stain through hole 211 and the sewage discharge port 103.

[0086] In this embodiment, the outer cylinder 201 includes a top frame 209 and a bottom frame 210. The bottom frame 210 is floatingly assembled in the top frame 209, and the cooperation of the inclined slot 212 and the square pin shaft 235 is used to drive the scraper 207 to move. In other embodiments, the outer cylinder 201 is of an integral structure, and at this time, the scraper 207 can be driven to slide manually.

[0087] In this embodiment, there are two gears 308. No matter how the loading module 200 is placed, there will always be one gear 308 meshing with the first rack 306 and the second rack 307. In other embodiments, only one gear 308 can be provided. At this time, when lowering the loading module 200, it is necessary to ensure that the side where the gear 308 is located corresponds to the side where the first rack 306 and the second rack 307 are located.

[0088] In this embodiment, the driving mechanism 300 includes a first rack 306, a second rack 307 and a gear 308, and drives the inner loading cylinder 203 to rotate by meshing. In other embodiments, the inner loading cylinder 203 can be manually rotated.

[0089] In this embodiment, there are five support mesh plates. In other embodiments, the number of support mesh plates can be increased or decreased according to actual conditions, or there can be only one support mesh plate.

[0090] In addition, in the description of this specification, the meaning of "a plurality" is at least two, such as two, three or more, etc., unless otherwise clearly and specifically defined.
