Description

Technical Field

[0001] This application relates to the technical field of disinfection equipment, and more particularly to a cup disinfection device. Background Technology

[0002] In daily life and office settings, teacups are frequently used drinking utensils, and their cleanliness directly affects the health and safety of users. Therefore, teacup cleaning devices that integrate washing and drying functions have gradually become mainstream products in the market. These devices typically transfer the teacups to a built-in drying chamber after high-pressure spraying or ultrasonic cleaning, where hot air circulation achieves rapid dehumidification and drying, effectively avoiding bacterial growth problems during natural air drying. To further enhance disinfection and meet users' higher requirements for the hygiene of drinking utensils, some high-end products also integrate a UV disinfection module in the drying chamber. Utilizing the destructive effect of ultraviolet light on microorganisms, the surface of the teacup is disinfected by irradiation after the drying process, thus achieving a complete cleaning process encompassing washing, drying, and disinfection. However, existing UV lamp disinfection modules still suffer from significant design flaws. On one hand, some products, in an effort to simplify structure and control costs, employ rudimentary protective measures for the UV lamps, relying solely on simple lampshades or brackets for fixation. This allows contaminants such as water droplets, tea stains, or dust splashed during cleaning to easily adhere to the lamp surface. This not only weakens the UV radiation intensity and reduces disinfection efficiency but may also cause short circuits and damage due to long-term moisture corrosion, severely impacting the module's lifespan. On the other hand, while some products prioritizing protective performance employ sealed shells and other structural designs, their overall structure is complex and contains numerous components. This not only increases manufacturing costs but also presents challenges such as cumbersome installation and inconvenient disassembly, making subsequent maintenance and repair difficult. These issues make it difficult for existing teacup cleaning devices' UV lamp disinfection modules to achieve a balance between protective performance, structural simplification, and ease of use, thus limiting the product's market competitiveness and user experience.

[0003] The purpose of this utility model embodiment is to provide a cup sterilization device that can solve the above-mentioned problems existing in related technologies.

[0004] To achieve the above objectives, this application adopts the following technical solution: A cup sterilization device, comprising: A container having an inner cavity for accommodating cups, the side wall of the container having a light-transmitting hole; A disinfection assembly is installed on the outer wall of the accommodating compartment. The disinfection assembly includes a mounting shell, a soft rubber shell, a light-transmitting plate, and a disinfection lamp. The light-transmitting plate and the disinfection lamp are installed inside the soft rubber shell. The soft rubber shell is fixed to the side of the mounting shell facing the accommodating compartment. The mounting shell is fixed to the accommodating compartment, so that the soft rubber shell forms a seal around the outer periphery of the light-transmitting hole. The disinfection lamp is aligned with the light-transmitting hole through the light-transmitting plate.

[0005] Optionally, the soft rubber shell is provided with a mounting groove that is open to the light-transmitting hole. The mounting groove is provided with a radially inwardly protruding annular inner rib on the side near the light-transmitting hole. The light-transmitting plate is installed in the mounting groove, and the periphery of the light-transmitting plate abuts against the side of the inner rib facing away from the light-transmitting hole to form a circumferential seal.

[0006] Optionally, the mounting groove is a through groove, with a mounting opening formed on the side away from the light-transmitting hole, through which the light-transmitting plate can be installed into the mounting groove.

[0007] Optionally, a rear cover plate is installed at the mounting port, and the disinfection lamp is located between the light-transmitting plate and the rear cover plate.

[0008] Optionally, the soft rubber shell is provided with a plurality of limiting ribs located on the side wall of the mounting groove at intervals. The limiting ribs abut against the side of the light-transmitting plate opposite to the inner convex rib, so that the light-transmitting plate remains tightly attached to the inner convex rib.

[0009] Optionally, the side wall of the soft rubber shell is provided with an insertion hole that extends laterally through the mounting groove. The disinfection lamp is inserted into the mounting groove through the insertion hole, and the power terminal of the disinfection lamp remains outside the soft rubber shell through the insertion hole.

[0010] Optionally, the disinfection lamp has a long strip-shaped body, and the soft rubber shell is long and strip-shaped, corresponding to the shape of the disinfection lamp; the insertion hole is provided on the side wall of the soft rubber shell perpendicular to its length direction.

[0011] Optionally, the mounting shell is provided with a receiving groove facing the side where the light-transmitting hole is located, and the soft rubber shell is installed into the receiving groove such that the periphery of the mounting shell abuts against the outer wall of the receiving compartment.

[0012] Optionally, the mounting shell is provided with supporting ribs located on the side wall of the receiving groove, the supporting ribs supporting the outer peripheral wall of the soft rubber shell.

[0013] Optionally, the outer wall of the accommodating compartment is welded with connecting lugs, and the mounting shell is connected and fixed to the connecting lugs by screws.

[0014] The beneficial effects of this application are as follows: The cup sterilization device provided by this utility model effectively solves the contradiction between poor protection and complex structure of the ultraviolet sterilization module in the prior art. It adopts a soft rubber shell and an annular sealing structure on the outer periphery of the light-transmitting hole, which can achieve efficient isolation between the container and the sterilization component through simple assembly. This avoids the corrosion of the sterilization lamp by moisture and contaminants, and eliminates the need for complex sealing components, simplifying the overall structure and installation process, and reducing production and maintenance costs. At the same time, the sterilization lamp, through the precise alignment design of the light-transmitting plate and the light-transmitting hole, ensures that ultraviolet rays directly hit the cup sterilization area without excess refraction loss, thus guaranteeing sterilization efficiency. The combined protection of the light-transmitting plate and the soft rubber shell does not affect the penetration of ultraviolet rays and extends the service life of the sterilization lamp. Ultimately, it achieves an organic unity of protective performance, structural simplification and ease of use, significantly improving the practicality and market competitiveness of the cup sterilization device.

[0021] In daily life and office settings, teacups are frequently used drinking utensils, and their cleanliness directly affects the health and safety of users. Therefore, teacup cleaning devices that integrate washing and drying functions have gradually become mainstream products in the market. These devices typically transfer the teacups to a built-in drying chamber after high-pressure spraying or ultrasonic cleaning, where hot air circulation achieves rapid dehumidification and drying, effectively avoiding bacterial growth problems during natural air drying. To further enhance disinfection and meet users' higher requirements for the hygiene of drinking utensils, some high-end products also integrate a UV disinfection module in the drying chamber. Utilizing the destructive effect of ultraviolet light on microorganisms, the surface of the teacup is disinfected by irradiation after the drying process, thus achieving a complete cleaning process encompassing washing, drying, and disinfection. However, existing UV lamp disinfection modules still suffer from significant design flaws. On one hand, some products, in an effort to simplify structure and control costs, employ rudimentary protective measures for the UV lamps, relying solely on simple lampshades or brackets for fixation. This allows contaminants such as water droplets, tea stains, or dust splashed during cleaning to easily adhere to the lamp surface. This not only weakens the UV radiation intensity and reduces disinfection efficiency but may also cause short circuits and damage due to long-term moisture corrosion, severely impacting the module's lifespan. On the other hand, while some products prioritizing protective performance employ sealed shells and other structural designs, their overall structure is complex and contains numerous components. This not only increases manufacturing costs but also presents challenges such as cumbersome installation and inconvenient disassembly, making subsequent maintenance and repair difficult. These issues make it difficult for existing teacup cleaning devices' UV lamp disinfection modules to achieve a balance between protective performance, structural simplification, and ease of use, thus limiting the product's market competitiveness and user experience.

[0022] To overcome the above technical problems, refer to Figures 1-4 This application provides a cup sterilization device, comprising: The container 1 has an inner cavity for accommodating cups, and the side wall of the container 1 is provided with a light-transmitting hole 11; The disinfection component 2 is installed on the outer wall of the accommodating chamber 1. The disinfection component 2 includes a mounting shell 21, a soft rubber shell 22, a light-transmitting plate 23, and a disinfection lamp 24. The light-transmitting plate 23 and the disinfection lamp 24 are installed inside the soft rubber shell 22. The soft rubber shell 22 is fixed to the side of the mounting shell 21 facing the accommodating chamber 1. The mounting shell 21 is fixed to the accommodating chamber 1, so that the soft rubber shell 22 forms a seal around the outer periphery of the light-transmitting hole 11. The disinfection lamp 24 is aligned with the light-transmitting hole 11 through the light-transmitting plate 23.

[0023] The container 1 serves as a space for holding and disinfecting cups. The light-transmitting hole 11 on its side wall provides a precise irradiation channel for the ultraviolet rays of the disinfection lamp 24. The outer wall of the container 1, which is used to install the disinfection component 2, needs to be tightly fitted with the soft rubber shell 22 of the disinfection component 2 to form a sealing reference surface, ensuring the isolation of the inner cavity of the container 1 from the external environment.

[0024] In the disinfection component 2, the disinfection lamp 24 serves as the ultraviolet emission source. Its installation position is precisely aligned with the light-transmitting plate 23 and the light-transmitting hole 11, ensuring that light can pass through the light-transmitting plate 23 and the light-transmitting hole 11 directly to the inner cavity of the accommodating chamber 1, avoiding light refraction or loss. The disinfection lamp 24 is preferably a 254nm ultraviolet mercury lamp or an LED ultraviolet lamp, balancing disinfection efficiency and service life. The light-transmitting plate 23 is preferably made of high-transmittance quartz glass or ultraviolet-resistant PC material, and is sealed inside the soft rubber shell 22, ensuring ultraviolet light transmittance while preventing dust and moisture from directly contacting the disinfection lamp 24, forming the first protective barrier. The soft shell 22 is integrally molded from elastic silicone or rubber material and fixed to the side of the mounting shell 21 facing the accommodating chamber 1. Its inner side is used to embed the light-transmitting plate 23 and the disinfection lamp 24, while its outer side is designed as a ring structure that fits the outer periphery of the light-transmitting hole 11. After assembly, the soft shell 22 can tightly fit the outer wall of the accommodating chamber 1, using its own elasticity to achieve a ring seal and prevent moisture and water droplets from penetrating into the disinfection component 2 from the inner cavity of the accommodating chamber 1. The mounting shell 21, as the fixing carrier and protective shell of the disinfection component 2, is made of hard plastic or metal material and can be fixedly connected to the outer wall of the accommodating chamber 1 by bolts, buckles, etc. It provides stable installation support for the soft shell 22, the light-transmitting plate 23, and the disinfection lamp 24, and can also isolate the internal components from the interference of the external environment, while facilitating later disassembly and maintenance.

[0025] When assembling the cup sterilization device of this embodiment, the light-transmitting plate 23 and the sterilization lamp 24 are first installed inside the soft rubber shell 22 to form an internal module. Then, the internal module is integrally installed onto the mounting shell 21. Finally, the mounting shell 21 is fixed to the outer wall of the accommodating chamber 1. After installation, the soft rubber shell 22 can tightly abut against the outer wall of the accommodating chamber 1 under the tight pressure of the mounting shell 21, forming a good sealing structure.

[0026] The light-transmitting plate 23 blocks the direct contact between the disinfection lamp 24 and the external environment, preventing tea stains and dust from adhering to the lamp body; the sealing structure of the soft rubber shell 22 blocks moisture penetration, preventing the disinfection lamp 24 from short-circuiting or degrading due to moisture, while also preventing residual pollutants from cleaning in the container 1 from contaminating the disinfection component 2.

[0027] The cup sterilization device provided in this embodiment effectively solves the contradiction between poor protection and complex structure of ultraviolet sterilization modules in the prior art. It adopts a ring-shaped sealing structure on the outer periphery of the soft rubber shell 22 and the light-transmitting hole 11, achieving efficient isolation between the containing chamber 1 and the sterilization component 2 through simple assembly. This avoids the corrosion of the sterilization lamp 24 by moisture and contaminants, eliminates the need for complex sealing components, simplifies the overall structure and installation process, and reduces production and maintenance costs. Simultaneously, the sterilization lamp 24, through the precise alignment design of the light-transmitting plate 23 and the light-transmitting hole 11, ensures that ultraviolet light directly hits the cup sterilization area without excessive refraction loss, guaranteeing sterilization efficiency. The combined protection of the light-transmitting plate 23 and the soft rubber shell 22 does not affect ultraviolet penetration and extends the service life of the sterilization lamp 24. Ultimately, it achieves an organic unity of protective performance, structural simplification, and ease of use, significantly improving the practicality and market competitiveness of the cup sterilization device.

[0028] In one embodiment, reference is made to Figures 6-8 The soft rubber shell 22 is provided with a mounting groove 221 that is open to the light-transmitting hole 11. The mounting groove 221 is provided with an annular inner rib 222 that protrudes radially inward on the side near the light-transmitting hole 11. The light-transmitting plate 23 is installed in the mounting groove 221. The periphery of the light-transmitting plate 23 abuts against the side of the inner rib 222 facing away from the light-transmitting hole 11 to form a circumferential seal.

[0029] The soft rubber shell 22 has an axially oriented mounting groove 221 on the side facing the light-transmitting hole 11 of the receiving compartment 1. The inner diameter of the mounting groove 221 is precisely matched with the outer diameter of the light-transmitting plate 23, ensuring that the light-transmitting plate 23 can be stably embedded without radial loosening. An annular inner rib 222 is integrally formed at the end of the mounting groove 221 near the light-transmitting hole 11, with the end face of the inner rib 222 designed as a smooth plane. Its inner diameter is smaller than the outer diameter of the light-transmitting plate 23, forming a limiting structure that fits the periphery of the light-transmitting plate 23. After the light-transmitting plate 23 is embedded in the mounting groove 221, its periphery exactly abuts against the end face of the inner rib 222 facing away from the light-transmitting hole 11. Utilizing the elastic properties of the soft rubber shell 22, the contact surfaces of the light-transmitting plate 23 and the inner rib 222 form a tight fit, thereby achieving a circumferential seal of the light-transmitting plate 23.

[0030] This embodiment, through the refined design of setting an annular inner rib 222 in the mounting groove 221 of the soft rubber shell 22, not only utilizes the elastic properties of the soft rubber to achieve precise positioning and tight sealing of the periphery of the light-transmitting plate 23, effectively blocking the risk of moisture and pollutants seeping into the area of ​​the disinfection lamp 24 along the gap between the light-transmitting plate 23 and the mounting groove 221, further improving the reliability of the protection of the disinfection lamp 24, but also eliminates the need for additional sealing gaskets and other components. While simplifying the assembly process and controlling production costs, it ensures the stability of the installation of the light-transmitting plate 23 and the penetration efficiency of ultraviolet rays.

[0031] In one embodiment, reference is made to Figure 8 The mounting groove 221 is a through groove, and a mounting opening 224 is formed on the side away from the light-transmitting hole 11. The light-transmitting plate 23 can be installed into the mounting groove 221 through the mounting opening 224.

[0032] The through-type mounting groove 221 forms an open mounting port 224, making the installation path of the light-transmitting plate 23 and the disinfection lamp 24 more direct. There is no need to avoid the structure of the inner convex rib 222 of the soft rubber shell 22. The light-transmitting plate 23 can be quickly inserted or removed from the mounting port 224 side, simplifying the assembly and disassembly process and reducing the assembly difficulty and later maintenance cost. After installation, the inner convex rib 222 tightly abuts against the light-transmitting plate 23 to form an effective seal.

[0033] In one embodiment, a rear cover plate 25 is installed at the mounting port 224, and the disinfection lamp 24 is located between the light-transmitting plate 23 and the rear cover plate 25.

[0034] The rear cover 25 adopts a structure adapted to the mounting port 224 (matching the shape of the mounting port 224 of the soft rubber shell 22), and is preferably made of hard plastic or thin metal sheet, possessing a certain structural strength to provide stable support. The rear cover 25 can be installed at the mounting port 224 of the mounting groove 221 by means of snap connection, screw fixing or interference fit, completely covering the mounting port 224 to form a closed structure.

[0035] In this embodiment, by adding a rear cover plate 25 at the mounting port 224 and defining the installation position of the disinfection lamp 24, a fully enclosed protective space is constructed for the disinfection lamp 24, effectively isolating external moisture, dust, and residual water vapor in the containment chamber 1. This significantly reduces the risk of damage to the disinfection lamp 24 due to contamination or moisture and extends its service life. At the same time, the coordinated positioning effect of the rear cover plate 25 and the light-transmitting plate 23 ensures the precise alignment of the disinfection lamp 24 and the light-transmitting hole 11, avoiding light deviation from affecting the disinfection effect and improving the disinfection stability of the device.

[0036] In one embodiment, reference is made to Figure 8 The soft rubber shell 22 is provided with a plurality of limiting ribs 223 located on the side wall of the mounting groove 221 at intervals. The limiting ribs 223 abut against the side of the light-transmitting plate 23 facing away from the inner convex rib 222, so that the light-transmitting plate 23 remains tightly attached to the inner convex rib 222.

[0037] The inner convex rib 222 limits the light-transmitting plate 23 from the front (towards the light-transmitting hole 11), while the limiting rib 223 presses against it from the back (away from the light-transmitting hole 11). This bidirectional constraint completely restricts the axial displacement of the light-transmitting plate 23 within the mounting groove 221, improving the stability of the light-transmitting plate 23 and maintaining its high sealing performance. The spaced distribution of the limiting ribs 223 provides greater deformation space and allows for greater deformation. During assembly, the light-transmitting plate 23 can be easily inserted by pressing the limiting ribs 223, improving the ease of assembly.

[0038] In one embodiment, reference is made to Figures 6-8 The side wall of the soft rubber shell 22 is provided with an insertion hole 225 that laterally penetrates the mounting groove 221. The disinfection lamp 24 is inserted into the mounting groove 221 through the insertion hole 225, and the power terminal 241 of the disinfection lamp 24 is retained outside the soft rubber shell 22 through the insertion hole 225.

[0039] The insertion hole 225 is opened on the side wall of the soft rubber shell 22 and extends radially through the mounting groove 221. One end of the hole is connected to the inside of the mounting groove 221, and the other end extends to the outer side of the soft rubber shell 22, forming a channel for the disinfection lamp 24 to be inserted.

[0040] This embodiment greatly simplifies the installation and disassembly process of the disinfection lamp 24 by providing a lateral through-hole 225 on the side wall of the soft plastic shell 22. There is no need to disassemble components such as the light-transmitting plate 23 and the rear cover plate 25. The disinfection lamp 24 can be quickly replaced simply by using the through-hole 225, which significantly reduces the difficulty and cost of production assembly and subsequent maintenance. In addition, the power terminal 241 is retained on the outside of the soft plastic shell 22, which avoids the interference of the humid environment on the circuit connection, reduces the risk of short circuit, improves the electrical safety of the device, and also facilitates the circuit connection.

[0041] In one embodiment, the disinfection lamp 24 is a long strip-shaped lamp body, and the soft rubber shell 22 is a long strip-shaped structure corresponding to the shape of the disinfection lamp 24; the insertion hole 225 is provided on the side wall of the soft rubber shell 22 perpendicular to its length direction.

[0042] The disinfection lamp 24 adopts a long strip-shaped lamp body structure, and its light emission is evenly distributed along its length, which can achieve ultraviolet coverage of a larger area within the containment chamber 1. The soft plastic shell 22 is designed to be a long strip shape that matches the shape of the disinfection lamp 24. Its internal mounting groove 221 is also long strip-shaped, and the length and width of the groove are adapted to the size of the disinfection lamp 24 body to ensure that the disinfection lamp 24 does not wobble after insertion. The insertion hole 225 is located on the side wall of the soft plastic shell 22 perpendicular to its length direction (i.e., the side walls at both ends of the soft plastic shell 22), and extends laterally along the width direction of the soft plastic shell 22 to the internal mounting groove 221. The insertion hole 225 at this position is small in size, which minimizes the impact on the structural stability of the soft plastic shell 22.

[0043] In one embodiment, combined with Figure 5 and Figure 6 The mounting shell 21 is provided with a receiving groove 211 facing the side where the light-transmitting hole 11 is located. The soft rubber shell 22 is installed into the receiving groove 211, so that the periphery of the mounting shell 21 abuts against the outer wall of the receiving chamber 1.

[0044] The receiving groove 211 is a recessed structure formed by the mounting shell 21 facing the outer wall of the receiving compartment 1. The shape and size of the groove match the shape of the soft rubber shell 22. Since the soft rubber shell 22 is elongated, the receiving groove 211 is also designed to be elongated. The length and width of the groove match the external dimensions of the soft rubber shell 22, and the depth of the groove matches the thickness of the soft rubber shell 22 (usually slightly less than the thickness of the soft rubber shell 22 to ensure that part of the soft rubber shell 22 protrudes from the receiving groove 211 after installation). The inner wall of the receiving groove 211 can be provided with positioning bosses or buckles, which match the positioning holes or slots on the back of the soft rubber shell 22 to achieve precise positioning of the soft rubber shell 22 and prevent lateral displacement.

[0045] When the mounting shell 21 is fixed, the soft rubber shell 22 protruding from the receiving groove 211 undergoes elastic deformation under the pressure of the mounting shell 21 and the outer wall of the receiving chamber 1, making its contact surface with the outer periphery of the light-transmitting hole 11 tighter, completely blocking the path of moisture in the receiving chamber 1 to the outside; at the same time, the periphery of the mounting shell 21 abuts against the outer wall of the receiving chamber 1 to form an auxiliary seal, forming a double protection with the main seal of the soft rubber shell 22, further isolating external dust and moisture from entering through the gap between the mounting shell 21 and the receiving chamber 1; in addition, the enveloping effect of the receiving groove 211 on the soft rubber shell 22 prevents excessive deformation of the soft rubber shell 22 due to long-term use or changes in ambient temperature, maintaining the stability of the sealing structure.

[0046] In one embodiment, the mounting shell 21 is provided with a support rib 212 located on the side wall of the receiving groove 211, and the support rib 212 supports the outer peripheral wall of the soft rubber shell 22.

[0047] When the soft plastic shell 22 is inserted into the receiving groove 211, the supporting ribs 212 on both sides of the receiving groove 211 will form a tight abutment with the outer peripheral wall of the soft plastic shell 22, providing limiting support for the soft plastic shell 22 from the periphery; if there is a slight dimensional deviation in the outer peripheral wall of the soft plastic shell 22, the supporting ribs 212 can limit the lateral displacement of the soft plastic shell 22 through their own rigid structure, ensuring that the soft plastic shell 22 is always in the center position of the receiving groove 211 and is precisely aligned with the light-transmitting hole 11.

[0048] In one embodiment, a connecting lug 26 is welded to the outer wall of the accommodating compartment 1, and the mounting shell 21 is connected and fixed to the connecting lug 26 by screws.

[0049] The connecting lug 26 has a threaded hole (or a smooth hole, or a smooth hole if a nut is used) at its center to match the screw. The specifications of the threaded hole match the screw through hole on the mounting shell 21. The connecting lug 26 is welded to the outer wall of the accommodating chamber 1 by argon arc welding, resistance welding, or other methods. The mounting shell 21 has a screw through hole corresponding to the position of the connecting lug 26. The diameter of the through hole is slightly larger than the diameter of the screw shank to ensure that the screw can pass through smoothly. During assembly, align the receiving groove 211 of the mounting shell 21 with the soft rubber shell 22 and fit it against the outer wall of the accommodating chamber 1, so that the screw through hole on the mounting shell 21 is precisely aligned with the threaded hole of the connecting lug 26. Then, pass the screw through the through hole of the mounting shell 21 and screw it into the threaded hole of the connecting lug 26 until the screw head presses against the surface of the mounting shell 21, thereby achieving a rigid fixation between the mounting shell 21 and the accommodating chamber 1.

[0050] This embodiment, by welding connecting ears 26 to the outer wall of the accommodating chamber 1 and fixing the mounting shell 21 with screws, not only utilizes the rigid structure of the welded connecting ears 26 and the stable fastening force of the screw connection to achieve long-term reliable fixation of the mounting shell 21 to the accommodating chamber 1, effectively preventing loosening or displacement of the mounting shell 21 due to vibration, impact, or temperature changes, ensuring the alignment accuracy and sealing performance of the soft rubber shell 22 and the light-transmitting hole 11, and preventing light deviation or moisture infiltration of the disinfection lamp 24; it also ensures that the evenly distributed connecting ears 26 and screws ensure that the compressive pressure of the mounting shell 21 on the soft rubber shell 22 is along the direction of the light. The circumferential uniform transmission enhances the elastic sealing effect of the soft rubber shell 22, further improving the device's moisture-proof and pollution-proof capabilities. In addition, the detachable nature of the screw connection facilitates the disassembly and installation of the shell 21 during later maintenance, reducing the difficulty of replacing the soft rubber shell 22 and the disinfection lamp 24. The metal material and welding fixing method of the connecting ear 26 ensure structural strength and adapt to long-term high-frequency use scenarios. Ultimately, it achieves a balance between fixing stability, sealing reliability, and maintenance convenience, while also taking into account the maturity of welding technology in industrial production and the assembly efficiency of screw connections, making it more suitable for mass production applications.
