[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0037] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0038] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0039] Referring to Figures 1 to 8, a discharge device is provided according to a specific embodiment of this application.

[0040] The discharge device includes a housing 1 and a drive assembly 2. The housing 1 has a receiving cavity 5. The housing 1 includes a door assembly 11. The door assembly 11 has a closed position that closes the receiving cavity 5. The door assembly 11 has multiple open positions that at least partially open the receiving cavity 5. The drive assembly 2 is located within the receiving cavity 5. The drive assembly 2 includes a guide rail 21 and a slider 22. The guide rail 21 is connected to the housing 1. A first gap is provided between the guide rail 21 and the housing 1. The slider 22 is slidably connected to the guide rail 21 so that the slider 22 can drive the door assembly 11 to the closed position and the open position. The angle formed with the horizontal plane is different when the door assembly is in different open positions.

[0041] By applying the technical solution of this utility model, a first gap is provided between the guide rail 21 and the housing 1, making it less likely for oil fumes to accumulate on the slider 22 during the driving of the door assembly 11. Compared with the existing structure, this solution reduces the possibility of jamming, reduces movement resistance, and lowers the parallelism requirement between the guide rail 21 and the slider 22, thus improving the overall structural tolerance. The technical solution of this application effectively solves the problem of poor operational stability of the discharge equipment in the prior art.

[0042] Through the precise cooperation between the slider and the guide rail, the opening and closing of the door structure is smoother, reducing noise and vibration during operation and improving efficiency and user comfort. Driven by the slider, the door structure operates smoothly, reducing jamming and wobbling, effectively improving the stability and reliability of the feeding equipment. In contrast, existing linear guide rails lack surface treatment, structural fault-tolerant design, and protection, making them prone to oil fume accumulation and jamming after a period of operation. The optical axis guide rail, being suspended in the air, accumulates less oil fume compared to linear guide rails mounted at the bottom of the dry material hopper, and offers better fault-tolerant performance.

[0043] Furthermore, the discharge device also includes a discharge assembly 3 and a receiving box 4. The discharge assembly 3 is located inside the receiving cavity 5 and has a discharge port. The receiving box 4 has a receiving position located at the bottom of the discharge port and a conveying position that moves at least partially outside the receiving cavity 5. The receiving box 4 is connected to at least one of the slider 22 and the door assembly 11. The receiving box 4 and the slider 22 drive the door assembly 11, thereby moving the receiving box 4 to the receiving position and the conveying position.

[0044] This design allows for more precise movement of the receiving box, preventing spillage of seasonings during dispensing and ensuring cleanliness during the feeding process. The linkage design between the receiving box and the slider makes the receiving and transportation of seasonings more accurate and efficient. By precisely controlling the movement of the receiving box, losses during seasoning processing can be reduced, and environmental pollution inside the equipment caused by spillage can be avoided. Furthermore, using the slider 22 to drive the receiving box 4 can also prevent seasoning spillage caused by equipment vibration, maintaining the cleanliness of the internal environment of the equipment. At this time, the slider 22, while driving the door assembly to open or close, also cooperates in controlling the movement of the receiving box 4.

[0045] Specifically, the material receiving box and the door assembly move in the following manner: (1) the slider moves backward and the door assembly opens to feed the material; (2) the slider moves forward and the door assembly closes, and the material receiving box is used to catch some delayed-falling seasonings.

[0046] Optionally, the receiving box can first be connected to the receiving box bracket, then connected to the connecting bracket 8 through the receiving box bracket, and finally connected to the slider through the connecting bracket 8.

[0047] As shown in Figure 6, in an optional embodiment, one end of the connecting bracket 8 is connected to the slider 22, and the other end of the connecting bracket 8 is connected to the receiving box. The connecting bracket 8 is preferably a sheet metal part, which has limited rigidity and is prone to deformation during processing. Multiple oblong holes are provided on the connecting bracket 8 to absorb deformation.

[0048] This linkage mechanism simplifies the equipment structure and reduces maintenance costs, especially in space-constrained kitchen feeding systems, improving the equipment's flexibility and adaptability. The linkage mechanism, which uses a slider to drive the door structure and thus move the receiving box, not only simplifies the equipment's structure but also improves space utilization and ease of operation, effectively saving space and increasing production efficiency.

[0049] As shown in Figure 2, the drive assembly 2 also includes a base 23. The base 23 is connected to the first side wall of the housing 1, and the guide rail 21 is connected to the base 23. The guide rail 21 is disposed on the side of the base 23 away from the first side wall, and a second gap is provided between the guide rail 21 and the base 23.

[0050] Specifically, the second gap is smaller than the first gap. For example, when the gap between the guide rail and the first sidewall is 5mm, the gap between the guide rail 21 and the first sidewall is 3mm. However, since there is a gap between the guide rail 21 and the base 23, it still serves to prevent oil fume deposition.

[0051] The separate design of the base and guide rails ensures that wear on the guide rails does not directly affect the stability of the base, extending the service life of the equipment. This separation not only improves the stability and durability of the equipment but also facilitates guide rail replacement and maintenance. Furthermore, the secondary gap design prevents oil fume accumulation and ensures that even with some wear on the guide rails over long-term use, the overall performance of the discharge equipment remains unaffected, guaranteeing high efficiency and reliability during continuous operation.

[0052] In one optional embodiment, the guide rail 21 is an optical axis, meaning its circumferential surface is a smooth curved surface with certain surface roughness requirements. The optical axis guide rail solution allows for non-destructive replacement of existing linear guide rails, facilitating maintenance of commercially available machines.

[0053] Furthermore, the first sidewall is the bottom or top wall of the receiving cavity 5, and the guide rail 21 is a shaft-like structure with the axial direction of the guide rail 21 parallel to the first sidewall.

[0054] This layout allows the guide rail 21 to occupy less space in the vertical direction, while limiting the working direction of the slider to be parallel to the first side wall. The layout of the guide rail axis being parallel to the first side wall makes the operation of the discharge device smoother and more stable in the discharge direction, reducing the shaking and spillage of the seasoning during the conveying process.

[0055] Furthermore, the pattern formed by the radial cross-section of the guide rail 21 is circular or elliptical.

[0056] The circular or elliptical guide rail cross-section design provides more uniform sliding resistance, ensuring smooth movement of the slider on the guide rail and guaranteeing the stability of the feeding process and product quality. The circular or elliptical guide rail cross-section design also avoids jamming and wear caused by excessive local friction. Referring to Figure 2, the drive assembly 2 also includes a drive component 24 and a transmission structure 25. The transmission structure 25 is connected to the output end of the drive component 24 and is also connected to the slider 22.

[0057] This transmission structure design efficiently and stably transmits the power of the drive component to the slider, improving the load-bearing capacity and operating efficiency of the discharge equipment. Using a motor as the drive component, combined with a rack and pinion transmission structure, ensures a stable and powerful driving force for the door assembly or material-bearing component. This design not only improves the load-bearing capacity and operating efficiency of the discharge equipment but also ensures the continuity and reliability of the discharge process, reducing equipment failures caused by insufficient driving force or unstable transmission.

[0058] As shown in Figure 2, the driving component 24 is a motor, and the transmission structure 25 includes a gear 251 and a rack 252. The gear 251 meshes with the rack 252, the gear 251 is connected to the output end of the motor, and the rack 252 is connected to the slider 22. The extending direction of the rack 252 is parallel to the axial direction of the guide rail 21.

[0059] The motor-driven rack and pinion transmission not only provides precise control but also ensures long-term operational reliability. It is suitable for scenarios requiring precise control of the output, ensuring the controllability of the feeding process. The rack and pinion structure allows the transmission structure 25 to utilize space in both the width and height directions of the equipment, resulting in a more compact overall transmission structure.

[0060] Motor-driven rack and pinion transmission systems have become an ideal choice for achieving precise material output control due to their precise control and long-term operational reliability. They also provide technical support for the standardization and automation of the feeding process, thereby improving feeding efficiency.

[0061] In another alternative embodiment, the drive element 24 can be a cylinder, which would eliminate the need for a gear and rack transmission mechanism.

[0062] Furthermore, a telescopic protective sleeve is fitted onto the outer side of the guide rail 21. This telescopic protective sleeve is elastically designed so that it can deform as the slider 22 slides relative to the guide rail 21. The telescopic protective sleeve can be a bellows-like device. Optical axis guide rails are convenient for adding bellows-like telescopic protective sleeves to prevent oil fumes from accumulating on the guide rail surface.

[0063] The housing 1 includes a first seat and a second seat disposed opposite to each other. The first seat is connected to a first end of the slider 22 along its length and the first seat is connected to a second end of the slider 22 along its length. The telescopic protective sleeve includes a first protective sleeve and a second protective sleeve. The two ends of the first protective sleeve are respectively connected to the first seat and the first end, and the two ends of the second protective sleeve are respectively connected to the second seat and the second end.

[0064] Optionally, the telescopic protective sleeve can also be configured as a single unit. When there is only one telescopic protective sleeve, it is located between the first base and the first end, or between the second base and the second end.

[0065] During the sliding process of slider 22 relative to guide rail 21, the deformation directions of the first protective sleeve and the second protective sleeve are opposite. This arrangement ensures that throughout the entire stroke of slider 22, the first and second protective sleeves work together to protect the guide rail from being exposed to the working environment.

[0066] Optionally, the two ends of the protective sleeve are connected to the shaft via a snap-fit ​​structure, with O-rings embedded in the snaps (to prevent liquid leakage). The telescopic protective sleeve has continuous pleats, which are composed of V-shaped creases, with the included angle α between adjacent creases being 30° to 60°. This design improves axial rigidity and is suitable for high-frequency telescopic applications in kitchen appliances.

[0067] The telescopic protective sleeve effectively protects the guide rail from external environmental influences such as dust and moisture, making it suitable for handling seasonings in complex environments. This extends the equipment's lifespan and reduces maintenance frequency. The design of the telescopic protective sleeve not only effectively isolates the guide rail from external environmental influences but also reduces friction and wear on the slider during movement through its elastic deformation characteristics, improving the reliability and safety of the discharge equipment.

[0068] Furthermore, the slider 22 has a through hole, the guide rail 21 passes through the through hole, and a bearing is provided between the slider 22 and the guide rail 21. The end of the bearing is connected to a sealing gasket, which is sleeved on the guide rail 21. A sealing ring is also provided between the sealing gasket and the guide rail 21, and the sealing ring is located between the sealing gasket and the bearing.

[0069] The sealing gasket is preferably a silicone sealing gasket, and the sealing ring is preferably a fluororubber sealing ring, which can block particulate matter and isolate most of the oil fumes and moisture. In other words, the addition of a fluororubber sealing ring structure to the end face of the slider can prevent particulate matter such as seasonings from entering the linear bearing of the slider and causing the slider to jam.

[0070] The preferred bearing is a cobalt oxide ceramic ball bearing, which is a linear bearing, to solve the problem of steel balls rusting.

[0071] The multi-layer sealing structure further enhances the sealing performance between the slider and the guide rail, making it suitable for handling high-viscosity or corrosive seasonings. It protects the bearing's internal structure from seasoning contamination, improving the bearing's operational stability and safety. The multi-layer sealing design creates multiple layers of protection between the bearing and the guide rail, effectively isolating the bearing's internal structure from high-viscosity or corrosive seasonings, thus improving the operational stability and safety of the discharge equipment and reducing potential bearing damage and environmental pollution caused by seasoning leakage.

[0072] Furthermore, the door assembly 11 includes a door body 111 and a cover plate 112, the door body 111 and the cover plate 112 are connected, and the door body 111 and the cover plate 112 are provided with a sealing strip 113, the sealing strip 113 is made of elastic material, part of the cover plate 112 is located on the outside of the door body 111, and the sealing strip 113 is disposed between the door body 111 and the cover plate 112.

[0073] The flexible sealing strip design allows the door structure to fit tightly against the housing when closed, making it suitable for scenarios requiring a stable internal environment and protecting the quality of the internal seasonings. The use of the flexible sealing strip ensures a tight fit between the door structure and the housing, forming an effective sealing barrier that effectively isolates the external environment, preventing the intrusion of air, moisture, and other impurities. This protects the purity of the internal seasonings during the dispensing process, while also improving the quality and safety of the feeding equipment, providing consumers with a more reliable and healthier dispensing product.

[0074] As shown in Figures 7 and 8, the first end of the sealing strip 113 abuts against the cover plate 112, and the second end of the sealing strip 113 has an opening groove 119. The edge of the door body 111 extends into the opening groove 119. The sealing strip 113 also includes a buffer portion that protrudes along a first direction. The inner side of the buffer portion forms an arc-shaped buffer cavity 118. The first direction is the direction perpendicular to the plane where the door body 111 is located.

[0075] As shown in Figure 8, the door body 111 has a connecting hole. The door body 111 is connected to the cover plate 112 via a connecting assembly. The connecting assembly includes a welding block 114, a rubber gasket 115, a washer 116, and a connector 117. The welding block 114 is located between the welding block 114 and the door body 111, and is connected to both the door body 111 and the cover plate 112. The rubber gasket 115 is located between the welding block 114 and the door body 111. The connector 117 passes through the connecting hole and is connected to the welding block 114. The washer 116 is located on the side of the door body 111 facing away from the welding block 114, and is located between the connector 117 and the door body 111.

[0076] Washer 116 is used to cover the connection hole to prevent the through hole of the connector 117 (preferably screw) of the transparent PC cover from being exposed.

[0077] The rubber pad 115 is used to prevent the connector 117 from cracking the transparent PC cover plate, and at the same time to avoid the cover plate and the aluminum welded block from colliding and making abnormal noises.

[0078] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0079] The use of optical axis guide rails can prevent oil fume accumulation and has the advantages of low movement resistance, low parallelism requirements, and stronger fault tolerance.
