Description

Technical Field

[0001] This invention belongs to the technical field of food weighing and settlement equipment with lighting devices, specifically, it relates to a food weighing and settlement equipment with lighting devices. Background Technology

[0002] In supermarkets, markets, and shops, weighing equipment is typically used to determine the weight and price of goods when weighing items for customers. However, traditional weighing and settlement equipment has some problems. For example, it can be difficult to see the numbers, the quality of the items being weighed, and the price input during the weighing process when weighing in poor lighting conditions. Therefore, existing technology adds lights to the weighing equipment to improve the lighting effect. However, after prolonged use, the lampshade surface will accumulate stains, which will reduce the lighting effect. Especially in shops with heavy oil fumes, the fumes will adhere to the lampshade, resulting in a decrease in light transmittance and making it difficult to supplement the light source in low-light environments. To address this, we propose a food pick-up, weighing, and settlement device with an integrated lighting system. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a food weighing and settlement device with lighting that can overcome or at least partially solve the above problems.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a food weighing and settlement device with a lighting device, comprising: a connecting arm disposed on the weighing device, an inner lampshade disposed at one end of the connecting arm, and a lamp plate for illumination installed in the inner lampshade; an outer lampshade, fixedly connected to the connecting arm by a bracket, the inner wall of the outer lampshade having an external thread and the outer wall of the inner lampshade having an internal thread, for threaded connection between the inner and outer lampshades; a condensing lens disposed at the end of the outer lampshade away from the lamp plate in the inner lampshade, for adjusting the distance between the lamp plate and the condensing lens when the inner lampshade is rotated, thereby adjusting the focal length of the light emitted from the lamp plate from the end of the outer lampshade; a protective sheet disposed at one end of the outer lampshade, for providing sealing protection for the condensing lens; and a wiping strip disposed on the outer lampshade, the wiping strip being in contact with the protective sheet, and the wiping strip rotating around the axis of the outer lampshade when the inner lampshade is rotated to wipe the protective sheet.

[0005] Preferably, a connecting ring is rotatably connected to one end of the outer wall of the outer lamp cover, one end of the wiping strip is connected to the connecting ring, a guide rod is fixedly connected to the connecting ring, and an mounting arm is provided on the inner lamp cover. The mounting arm and the guide rod are slidably connected to each other so as to drive the wiping strip to rotate around the axis of the outer lamp cover when the inner lamp cover is driven to rotate.

[0006] Furthermore, the wiping strip is elongated, with one end located at the outer edge of the protective sheet and the other end extending to the center of the protective sheet.

[0007] Furthermore, an air cavity is provided in the connecting arm, and a slide rod with a piston at one end is fixedly connected to the inner lamp cover. The slide rod is slidably connected in the air cavity, and an air outlet pipe is installed in the slide rod. An air inlet pipe is provided on the slide rod, and one end of the air inlet pipe is connected to the air cavity. Both the air outlet pipe and the air inlet pipe are provided with one-way valves. The air outlet pipe leads to the inner lamp cover to dissipate heat from the lamp plate inside the inner lamp cover. The mounting arm is rotatably connected to the slide rod.

[0008] Furthermore, the inner lamp cover is provided with heat dissipation holes.

[0009] Furthermore, a mounting bracket is fixedly connected to the connecting ring, and a nozzle is mounted on the mounting bracket. One end of the nozzle faces the protective sheet, and when the inner lamp cover is rotated, the nozzle sprays liquid onto the protective sheet.

[0010] Furthermore, a piston cylinder is slidably connected to the bracket, and a piston rod with a piston at one end is slidably connected to the piston cylinder. An eccentric wheel is fixedly connected to the piston rod, and an inner concave connecting groove is formed on the outer circumference of the eccentric wheel. One end of the piston rod is slidably connected to the inner concave connecting groove away from the piston cylinder. An inlet pipe and an outlet pipe are fixedly connected to the piston cylinder, and a one-way valve is provided in both the inlet pipe and the outlet pipe. The outlet pipe is connected to the nozzle.

[0011] Furthermore, it also includes a locking ring connected to the weighing equipment, and a ball head is fixedly connected to one end of the connecting arm, the ball head being interference-fitted onto the locking ring.

[0012] Preferably, the weighing device includes a base, a weighing plate, a connecting column, and a display and operation screen. The weighing plate is disposed on the base, the connecting column is mounted on the base, the display and operation screen is disposed on the connecting column, and the locking ring is sleeved and locked onto the connecting column.

[0013] A method for using a food weighing and settlement device with a lighting device mainly includes the following steps: S1. By rotating the inner lamp cover, the distance between the lamp panel in the inner lamp cover and the condenser lens in the outer lamp cover is changed, thereby focusing the light emitted by the lamp panel, or by moving the lamp panel away from the condenser lens, the light emitted by the lamp panel is made softer and more diffused. S2. When rotating the inner lamp cover, the mounting arm is connected to the guide rod, which drives the connecting ring to rotate, thereby driving the wiping strip to rotate and clean the surface of the protective sheet. S3. When rotating the inner lamp cover, the inner lamp cover will drive the slide rod to rotate together. At this time, the slide rod rotates in the air cavity and slides. During the sliding process, the piston at one end of the slide rod squeezes the gas in the air cavity, so that the gas is blown into the inner lamp cover through the air outlet pipe to dissipate heat from the inner lamp cover. S4. When rotating the inner lamp cover, the piston cylinder is driven to spray liquid onto the protective sheet through the nozzle, thus wetting the protective sheet with the liquid.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention can change the distance between the lamp plate in the inner lamp cover and the condenser lens in the outer lamp cover, thereby focusing the light emitted by the lamp plate by changing the distance between the lamp plate and the condenser lens, or making the light emitted by the lamp plate softer and diffused by moving the lamp plate away from the condenser lens. This improves the practicality of the device during use, and allows the lamp plate to adapt to changing the lighting intensity when it is necessary to illuminate the inside of the weighing item. Furthermore, by using the nozzle and wiping strip to wipe and clean the stains on the protective sheet when rotating the inner lamp cover, the lighting effect of the weighing equipment is improved.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] Example 1: Refer to Figures 1-8 A weighing and settlement device for taking food with lighting includes: a connecting arm 2 mounted on a weighing device 1, with an inner lampshade 21 at one end of the connecting arm 2, and a lamp panel 22 for lighting installed in the inner lampshade 21; an outer lampshade 23 fixedly connected to the connecting arm 2 via a bracket 236, with external threads on the inner wall of the outer lampshade 23 and internal threads on the outer wall of the inner lampshade 21 for threaded connection between the inner lampshade 21 and the outer lampshade 23; and a condenser lens 231 disposed on the outer lampshade 23 away from the inner lampshade 21. One end of the plate 22 is used to adjust the distance between the lamp plate 22 and the condenser lens 231 when the inner lamp cover 21 is rotated, thereby adjusting the focal length of the light emitted from the outer lamp cover 23 by the lamp plate 22; the protective sheet 232 is provided on one end of the outer lamp cover 23 to provide sealing protection for the condenser lens 231; the wiping strip 234 is provided on the outer lamp cover 23, and the wiping strip 234 is in contact with the protective sheet 232. When the inner lamp cover 21 is rotated, the wiping strip 234 rotates around the axis of the outer lamp cover 23 to wipe the protective sheet 232. In use, the inner lampshade 21 and the outer lampshade 23 are threadedly connected to each other, and the outer lampshade 23 is fixed by the bracket 236. When the inner lampshade 21 is rotated, the external thread inside the outer lampshade 23 engages with the internal thread outside the inner lampshade 21, allowing the inner lampshade 21 to extend and retract within the outer lampshade 23. This allows the lamp plate 22 in the inner lampshade 21 to change the distance between itself and the condenser lens 231 inside the outer lampshade 23. By changing the distance between the lamp plate 22 and the condenser lens 231, the light emitted by the lamp plate 22 can be focused, or the light emitted by the lamp plate 22 can be softened and diffused by moving the lamp plate 22 away from the condenser lens 231. This improves the practicality of the device during use and allows the lamp plate 22 to adapt to changing the lighting intensity when it is necessary to illuminate the inside of a weighted object. This allows the light emitted by the lamp panel 22 to be brighter and thus improve the lighting effect by changing the distance between the lamp panel 22 and the condenser lens 231 after the surface of the protective sheet 232 is contaminated with stains. In addition, by setting up a wiping strip 234, this device can wipe and clean the surface of the protective sheet 232 while changing the light of the lamp panel 22 by driving the wiping strip 234 to rotate around the axis of the outer lamp cover 23, so that the light transmittance of the protective sheet 232 is better. This allows the device to provide better illumination for the weighing equipment 1 during use, especially when used in shops with heavy oil fumes. The surface of the protective sheet 232 can be cleaned by changing the distance between the light panel 22 and the focusing lens 231. It should be understood that the external threads on the outer lamp cover 23 and the internal threads in the inner lamp cover 21 have large pitches, so the required distance between the lamp plate 22 and the condenser lens 231 can be changed without rotating 360 degrees.

[0019] A connecting ring 233 is rotatably connected to one end of the outer wall of the outer lamp cover 23. One end of the wiping strip 234 is connected to the connecting ring 233. A guide rod 235 is fixedly connected to the connecting ring 233. An installation arm 237 is provided on the inner lamp cover 21. The installation arm 237 and the guide rod 235 are slidably connected to each other, so as to drive the wiping strip 234 to rotate around the axis of the outer lamp cover 23 when the inner lamp cover 21 is driven to rotate. When the inner lamp cover 21 is rotated, the mounting arm 237 is connected to the guide rod 235, which drives the connecting ring 233 to rotate, thereby driving the wiping strip 234 to rotate and clean the surface of the protective sheet 232.

[0020] The wiping strip 234 is long and narrow, with one end of the wiping strip 234 located at the outer edge of the protective sheet 232 and the other end of the wiping strip 234 extending to the center of the protective sheet 232. The wiping strip 234 is long and narrow, which can reduce the area covered by the protective sheet 232, thereby avoiding a reduction in the light-shielding area. In addition, the long and narrow wiping strip 234 can thoroughly clean the surface of the protective sheet 232 when the inner lamp cover 21 is rotated. Furthermore, the wiping strip 234 is made of transparent material, which can further reduce the impact on light blocking.

[0021] An air cavity 213 is provided in the connecting arm 2. A slide rod 212 with a piston at one end is fixedly connected to the inner lamp cover 21. The slide rod 212 is slidably connected in the air cavity 213. An air outlet pipe 214 is installed in the slide rod 212. An air inlet pipe 215 is provided on the slide rod 212. One end of the air inlet pipe 215 is connected to the air cavity 213. A one-way valve is provided in both the air outlet pipe 214 and the air inlet pipe 215. The air outlet pipe 214 leads to the inner lamp cover 21 for heat dissipation of the lamp plate 22 inside the inner lamp cover 21. The mounting arm 237 is rotatably connected to the slide rod 212. When the inner lamp cover 21 is rotated, the inner lamp cover 21 will drive the slide rod 212 to rotate together. At this time, the slide rod 212 rotates and slides in the air cavity 213. During the sliding process, the piston at one end of the slide rod 212 compresses the gas in the air cavity 213, so that the gas is blown into the inner lamp cover 21 through the air outlet pipe 214 to dissipate heat from the inner lamp cover 21 and effectively improve the service life of the lamp panel 22.

[0022] The inner lamp cover 21 has heat dissipation holes 211. By opening heat dissipation holes 211 on the inner lamp cover 21, the heat dissipation effect of the inner lamp cover 21 can be further improved.

[0023] Example 2: Refer to Figures 1-8 A weighing and settlement device for taking food with lighting includes: a connecting arm 2 mounted on a weighing device 1, with an inner lampshade 21 at one end of the connecting arm 2, and a lamp panel 22 for lighting installed in the inner lampshade 21; an outer lampshade 23 fixedly connected to the connecting arm 2 via a bracket 236, with external threads on the inner wall of the outer lampshade 23 and internal threads on the outer wall of the inner lampshade 21 for threaded connection between the inner lampshade 21 and the outer lampshade 23; and a condenser lens 231 disposed on the outer lampshade 23 away from the inner lampshade 21. One end of the plate 22 is used to adjust the distance between the lamp plate 22 and the condenser lens 231 when the inner lamp cover 21 is rotated, thereby adjusting the focal length of the light emitted from the outer lamp cover 23 by the lamp plate 22; the protective sheet 232 is provided on one end of the outer lamp cover 23 to provide sealing protection for the condenser lens 231; the wiping strip 234 is provided on the outer lamp cover 23, and the wiping strip 234 is in contact with the protective sheet 232. When the inner lamp cover 21 is rotated, the wiping strip 234 rotates around the axis of the outer lamp cover 23 to wipe the protective sheet 232. A connecting ring 233 is rotatably connected to one end of the outer wall of the outer lamp cover 23. One end of the wiping strip 234 is connected to the connecting ring 233. A guide rod 235 is fixedly connected to the connecting ring 233. An installation arm 237 is provided on the inner lamp cover 21. The installation arm 237 and the guide rod 235 are slidably connected to each other, so as to drive the wiping strip 234 to rotate around the axis of the outer lamp cover 23 when the inner lamp cover 21 is driven to rotate. The wiping strip 234 is long and narrow, with one end of the wiping strip 234 located at the outer edge of the protective sheet 232 and the other end of the wiping strip 234 extending to the center of the protective sheet 232. An air cavity 213 is provided in the connecting arm 2. A slide rod 212 with a piston at one end is fixedly connected to the inner lamp cover 21. The slide rod 212 is slidably connected in the air cavity 213. An air outlet pipe 214 is installed in the slide rod 212. An air inlet pipe 215 is provided on the slide rod 212. One end of the air inlet pipe 215 is connected to the air cavity 213. One-way valves are provided in both the air outlet pipe 214 and the air inlet pipe 215. The air outlet pipe 214 leads to the inner lamp cover 21 for heat dissipation of the lamp plate 22 inside the inner lamp cover 21. The mounting arm 237 is rotatably connected to the slide rod 212. Furthermore, a mounting bracket 24 is fixedly connected to the connecting ring 233. A nozzle 36 is installed on the mounting bracket 24. One end of the nozzle 36 faces the protective plate 232. When the inner lamp cover 21 is rotated, the nozzle 36 sprays liquid onto the protective plate 232. When the inner lamp cover 21 is rotated, the linkage nozzle 36 sprays liquid onto the protective sheet 232, which wets the protective sheet 232 and further improves the wiping effect of the protective sheet 232.

[0024] A piston cylinder 3 is slidably connected to the bracket 236. A piston rod 31 with a piston at one end is slidably connected to the piston cylinder 3. An eccentric wheel 32 is fixedly connected to the slide rod 212. An inward connecting groove 33 is opened on the outer periphery of the eccentric wheel 32. One end of the piston rod 31 is slidably connected to the inward connecting groove 33 away from the piston cylinder 3. An inlet pipe 34 and an outlet pipe 35 are fixedly connected to the piston cylinder 3. A one-way valve is provided in both the inlet pipe 34 and the outlet pipe 35. The outlet pipe 35 is connected to the nozzle 36. By holding the eccentric wheel 32, the inner lamp cover 21 is rotated, and the inner lamp cover 21 rotates the slide rod 212. At this time, the eccentric wheel 32 will push or pull the piston rod 31, squeeze the liquid in the piston cylinder 3 and spray it out into the nozzle 36 through the liquid outlet pipe 35. When the eccentric wheel 32 pulls the piston rod 31, liquid is drawn into the piston cylinder 3 through the liquid inlet pipe 34; It is important to understand that by setting up a liquid storage bottle, one end of the liquid inlet tube 34 is inserted into the liquid storage bottle to facilitate the liquid inlet tube 34 drawing liquid.

[0025] Example 3: Reference Figures 1-8A weighing and settlement device for taking food with lighting includes: a connecting arm 2 mounted on a weighing device 1, with an inner lampshade 21 at one end of the connecting arm 2, and a lamp plate 22 for illumination installed in the inner lampshade 21; an outer lampshade 23 fixedly connected to the connecting arm 2 via a bracket 236, with external threads on the inner wall of the outer lampshade 23 and internal threads on the outer wall of the inner lampshade 21 for threaded connection between the inner lampshade 21 and the outer lampshade 23; and a condenser lens 231 located at the end of the outer lampshade 23 away from the lamp plate 22 in the inner lampshade 21, for adjusting the lamp plate 22 and the condenser lens 23 when the inner lampshade 21 is rotated. The spacing between the two parts allows for adjustment of the focal length of the light emitted from one end of the outer lamp cover 23 by the lamp panel 22; the protective sheet 232 is disposed on one end of the outer lamp cover 23 to provide sealing protection for the condenser lens 231; the wiping strip 234 is disposed on the outer lamp cover 23 and is in contact with the protective sheet 232. When the inner lamp cover 21 is rotated, the wiping strip 234 rotates around the axis of the outer lamp cover 23 to wipe the protective sheet 232. Furthermore, it also includes a locking ring 26 connected to the weighing device 1, and a ball head 25 is fixedly connected to one end of the connecting arm 2. The ball head 25 is interference-fitted to the locking ring 26. The ball head 25 is movably connected to the locking ring 26 via an interference fit, and the lighting direction can be changed through the ball head 25; In addition, the connecting arm 2 can be connected to the locking ring 26 via a corrugated rod, thereby changing more lighting angles and making it easier to use.

[0026] The weighing device 1 includes a base 10, a weighing plate 11, a connecting column 12, and a display and operation screen 13. The weighing plate 11 is mounted on the base 10, the connecting column 12 is mounted on the base 10, the display and operation screen 13 is mounted on the connecting column 12, and the locking ring 26 is sleeved and locked onto the connecting column 12.

[0027] Example 4: Reference Figures 1-8 A method for using a food weighing and settlement device with lighting, mainly including the following steps: S1. By rotating the inner lamp cover 21, the distance between the lamp plate 22 in the inner lamp cover 21 and the condenser lens 231 in the outer lamp cover 23 is changed, thereby concentrating the light emitted by the lamp plate 22, or by moving the lamp plate 22 away from the condenser lens 231, the light emitted by the lamp plate 22 is made softer and diffused. S2. When rotating the inner lamp cover 21, the mounting arm 237 is connected to the guide rod 235, which drives the connecting ring 233 to rotate, thereby driving the wiping strip 234 to rotate and clean the surface of the protective sheet 232. S3. When rotating the inner lamp cover 21, the inner lamp cover 21 will drive the slide rod 212 to rotate together. At this time, the slide rod 212 rotates and slides in the air cavity 213. During the sliding process, the piston at one end of the slide rod 212 squeezes the gas in the air cavity 213, so that the gas is blown into the inner lamp cover 21 through the air outlet pipe 214 to dissipate heat from the inner lamp cover 21. S4. When rotating the inner lamp cover 21, the piston cylinder 3 is driven to spray liquid onto the protective sheet 232 through the nozzle 36, thereby wetting the protective sheet 232 with the liquid.

[0028] This invention allows the light plate 22 in the inner lamp cover 21 to change the distance between itself and the focusing lens 231 in the outer lamp cover 23. By changing the distance between the light plate 22 and the focusing lens 231, the light emitted by the light plate 22 can be focused, or the light emitted by the light plate 22 can be softened and diffused by moving the light plate 22 away from the focusing lens 231. This improves the practicality of the device during use and allows the light plate 22 to adapt to changing the lighting intensity when it is necessary to illuminate the inside of the weighing item. Furthermore, by using the nozzle 36 and wiping strip 234 to wipe and clean the stains on the protective sheet 232 when rotating the inner lamp cover 21, the lighting effect of the weighing equipment 1 is improved.

A vegetable weighing and settlement device with a lighting device according to claim 8, characterized in that, The weighing device (1) includes a base (10), a weighing plate (11), a connecting column (12), and a display and operation screen (13). The weighing plate (11) is mounted on the base (10), the connecting column (12) is mounted on the base (10), the display and operation screen (13) is mounted on the connecting column (12), and the locking ring (26) is sleeved and locked onto the connecting column (12).

10. A method of using a food weighing and settlement device with a lighting device, comprising the food weighing and settlement device with a lighting device as described in claim 7, characterized in that, The main steps include: S1. By rotating the inner lamp cover (21), the distance between the lamp plate (22) in the inner lamp cover (21) and the condenser lens (231) in the outer lamp cover (23) is changed, thereby concentrating the light emitted by the lamp plate (22), or by moving the lamp plate (22) away from the condenser lens (231), the light emitted by the lamp plate (22) becomes softer and diffused. S2. When rotating the inner lamp cover (21), the mounting arm (237) is connected to the guide rod (235), which drives the connecting ring (233) to rotate, thereby driving the wiping strip (234) to rotate to clean the surface of the protective sheet (232); S3. When rotating the inner lamp cover (21), the inner lamp cover (21) will drive the slide rod (212) to rotate together. At this time, the slide rod (212) rotates in the air cavity (213) and slides. During the sliding process, the piston at one end of the slide rod (212) squeezes the gas in the air cavity (213), so that the gas is blown into the inner lamp cover (21) through the air outlet pipe (214) to dissipate heat from the inner lamp cover (21). S4. When rotating the inner lamp cover (21), the piston cylinder (3) is driven to spray liquid onto the protective sheet (232) through the nozzle (36), and the liquid is used to wet the protective sheet (232).
