[0024] Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.
[0025] like Figure 1 and 2 As shown, the utility model provides a food gravity box, comprising a container 100 for storing food and a switch device 200 installed at the bottom of the container. The switch device 200 comprises a housing 210 provided with a flow channel, a feeding mechanism 220 for transferring food, a control module 230 for controlling the operation of the feeding mechanism 220, and a trigger switch 240. The container 100 is provided with a first feeding port 110, and the housing 210 is provided with a second feeding port 211. The first feeding port 110 is connected to the second feeding port 211 through a flow channel.
[0026] The control module 230 includes a display screen module 231 and a circuit board 232 for setting the weight of food. The display screen module 231, the feeding mechanism 220, the circuit board 232 and the trigger switch 240 are all installed on the housing 210. The circuit board 232 is electrically connected to the display screen module 231, the feeding mechanism 220 and the trigger switch 240 respectively. Pressing the trigger switch 240 causes the circuit board 232 to control the feeding mechanism 220 to discharge the food according to the food weight set by the display screen module 231. In this way, the weight of the food required by the consumer can be quickly obtained, which is simple and fast, and greatly optimizes the consumer's shopping experience.
[0027] Specifically, a mounting hole 212 is provided on the front end of the housing 210, and the display screen module 231 is disposed in the mounting hole 212 and mounted on the housing 210 through a fixing member 213. The circuit board 232 is mounted on the fixing member 213 and is located between the fixing member 213 and the display screen module 231. A sponge pad may be provided between the circuit board 232 and the fixing member 213 to play a buffering role and protect the circuit board 232.
[0028] In this embodiment, the display screen module 231 is a touch screen module, and can be operated directly by clicking on the display screen. The trigger switch 240 is also installed on the fixing member 213, and is preferably an Omron micro switch. Of course, the trigger switch 240 can also be installed in other positions, such as on the inner wall of the housing 210 or the outer wall of the housing 210. In order to improve the aesthetics, an LED light frame 214 can also be installed in the mounting hole 212.
[0029] like Figure 3 As shown, the feeding mechanism 220 includes a transmission cylinder 221, a screw 222 for transferring food, and a power unit 223. The transmission cylinder 221 is provided with a feed port 224 and a discharge port 225. The feed port 224 is communicated with the first discharge port 110, and the discharge port 225 is communicated with the second discharge port 211. The screw 222 is movably arranged in the transmission cylinder 221, and the power unit 223 is connected to the screw 222 to drive the screw 222 to rotate. In this embodiment, the transmission cylinder 221 is cylindrical. When the screw 222 is placed in the transmission cylinder 221, the gap between the screw 222 and the inner wall of the transmission cylinder 221 is small to prevent food from leaking through the gap.
[0030] Specifically, a mounting box 226 is provided at one end of the transmission cylinder 221, and the mounting box 226 is connected to the transmission cylinder 221. The power unit 223 is arranged in the mounting box 226 and is connected to the screw 222. In this embodiment, the mounting box 226 is arranged opposite to and connected to the discharge port 225. The power unit 223 is preferably a motor, which is connected to the screw 222. The motor drives the screw 222 to rotate, transfers the food from the feed port 224 to the discharge port 225, and drops from the second discharge port. Under the condition that the cross-sectional area of the transmission cylinder 221 is constant, the control module 230 controls the weight of the falling food by controlling the running time of the motor.
[0031] Furthermore, the unloading mechanism 220 also includes a guide kit 227, which is arranged in the flow channel and includes a first guide plate 10, a second guide plate 20 and a third guide plate 30. The first guide plate 10 is arranged opposite to the second guide plate 20, and the third guide plate 30 is connected to the first guide plate 10 and the second guide plate 20 respectively.
[0032] In this embodiment, the sleeve 227 is funnel-shaped as a whole and is integrally formed with the transmission cylinder 221. The sleeve 227 separates the flow channel and allows food to enter only from the feed port 224 of the transmission cylinder 221 and exit from the discharge port 225 through the guide plate, thereby preventing food from leaking from the side of the transmission cylinder 221, thereby affecting the weight of the falling food.
[0033] like Figure 2As shown, the switch device 200 further includes a manual assembly 250, which is rotatably mounted on the housing 210. Since the trigger switch 240 is located inside the housing 210, the trigger switch 240 can be conveniently pressed by rotating the manual assembly 250.
[0034] For reference Figure 4 The manual assembly 250 includes a handle 251, a trigger plate 252, and a reset member 253 that provides a restoring force for the handle 251. The handle 251 is rotatably mounted on the housing 210 and is located outside the housing 210. The trigger plate 252 is fixed on the handle 251 and is located inside the housing 210. Figure 5 As shown, by rotating the handle 251 , the trigger plate 252 presses the trigger switch 240 .
[0035] like Figure 6 As shown, the first guide plate 10 and the second guide plate 20 are both provided with positioning holes 40, and the trigger plate 252 is provided with positioning posts 254 that cooperate with the positioning holes. After assembly, the positioning posts 254 are clamped in the positioning holes 40, and the trigger plate 252 is rotatably mounted on the housing 210 and also rotatably mounted on the kit 227. This structure can make the trigger plate 252 rotate more stably.
[0036] In this embodiment, the reset member 253 is a reset rod made of thermoplastic polyurethane elastomer, one end of the reset rod is connected to the manual assembly 250, and the other end is connected to the housing 210. Of course, the reset member 253 can also be a torsion spring, a rubber band, etc.
[0037] In order to facilitate the installation of the reset member 253 , a first mounting column 50 is provided on the transmission cylinder 221 , a second mounting column 60 is provided on the trigger plate 252 , and both ends of the reset member 253 are connected to the first mounting column 50 and the second mounting column 60 , respectively.
[0038] like Figure 7 As shown, in order to prevent the manual assembly 250 from rotating excessively, the housing 210 is provided with a first limit portion 70 and a second limit portion 80. When the manual assembly 250 rotates and presses the trigger switch 240, the manual assembly 250 abuts against the second limit portion 80. Specifically, in the initial state, the handle 251 abuts against the first limit portion 70 (refer to Figure 1 ). refer to Figure 4 and Figure 5 When in use, the handle 251 is driven to rotate to drive the trigger plate 252 to rotate. When the trigger plate 252 presses the trigger switch 240, the trigger plate 252 abuts against the second limit portion 80 to prevent the trigger plate 252 from further crushing the trigger switch 240. When the trigger switch 240 is pressed, the reset member 253 is stretched. After the handle 251 is released, the handle 251 returns to the initial state under the action of the restoring force of the reset member 253.
[0039] In this embodiment, the switch device 200 further includes a decorative cover 260 for fixing the second feed opening 211. Since the housing 210 is composed of two half shells, the decorative cover 260 can fix the two half shells and also has a decorative effect.
[0040] In other embodiments, in order to prevent dust from entering the flow channel and contaminating food, the switch device 200 further includes a dust cover for sealing the second feed opening 211 .
[0041] The food gravity box of the utility model can store loose and granular food in the container 100. The weight of the required food is first set through the display module 231, and then the trigger switch 240 is pressed to make the circuit board 232 control the unloading mechanism 220 to discharge the food according to the food weight set by the display module 231. In this way, the weight of the food required by the consumer can be quickly obtained, and it is widely used in supermarkets and other places for sales or self-use. Multiple food gravity boxes can be arranged in different shapes according to actual needs, which is very suitable for promotion and use.
[0042] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
