Description

Technical Field

[0002] In the existing intelligent cooking system, through the combined use of a chip, a control program and various sensors, during the cooking process, various seasonings will be dispensed intelligently. After the seasonings in the container are dispensed, it is necessary to give a timely feedback prompt for replenishment, and at this time, a liquid level detection device needs to be used. The liquid level detection devices used on existing intelligent cooking equipment will have inaccurate liquid level height detection, and even false alarms may occur. At the same time, due to the relatively harsh use environment, the seasonings will splash everywhere, and the existing infrared detection devices will be affected by the splashed seasonings, resulting in unstable functions. Moreover, due to the fixed structure of the liquid level detection structure itself, the detected liquid level height is limited, and the detected liquid level height cannot be adjusted flexibly, so there will be a situation where a shortage of materials is reported when there is still a relatively large amount of seasonings remaining.

[0034] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0035] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0036] In the present utility model, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the present utility model.

[0037] In order to solve the problem of inaccurate detection of the liquid level of seasonings in the prior art, the present utility model provides a seasoning dispensing device.

[0038] As Figures 1 to 14 shown, a seasoning dispensing device includes a seasoning bottle for containing seasonings and a liquid level detection mechanism. The liquid level detection mechanism includes a detector 10 and a prism structure 20. The detector 10 has a transmitting end 11 and a receiving end 12; the prism structure 20 has an entrance and exit surface 21 and an inclined surface 22. The entrance and exit surface 21 and the inclined surface 22 are inclined relative to each other. The inclined surface 22 has an irradiation position. The signal from the transmitting end 11 is irradiated on the irradiation position through the entrance and exit surface 21, and after being reflected by the irradiation position, it is emitted from the entrance and exit surface 21 to the receiving end 12.

[0039] In this embodiment, by setting the prism structure 20, the signal is emitted to the receiving end 12 after being reflected by the irradiation position, so as to judge the liquid level of the seasonings in the seasoning bottle according to the difference of the signals received by the receiving end 12. Specifically, when the liquid level of the seasonings exceeds the critical liquid level and submerges the prism structure 20, the signal received by the receiving end 12 is different from the signal when the liquid level of the seasonings is lower than the critical liquid level and the prism structure 20 is exposed, so as to judge the liquid level of the seasonings and thus judge whether it is necessary to supplement the seasonings. This setting method has high reliability, accurate liquid level judgment, high waterproof level, and even if there is a situation of seasoning splashing and a little seasoning covers the surface of the liquid level detection mechanism, it will not affect the function of the liquid level detection mechanism, has a long service life, and the size of the liquid level detection mechanism is small and will not occupy too much volume of the seasoning bottle.

[0040] The principle of liquid level detection in this solution is as follows: Signals such as light are irradiated on the irradiation position of the inclined surface 22 through the entrance and exit surface 21. At this time, part of the light is reflected and part of the light is refracted. When the liquid level reaches the predetermined critical point, due to the different transmission media, the refraction situation of the light changes, so that the signal of the reflected light received by the detector 10 changes, causing changes in the voltage of the detection circuit, etc., and then determining whether the liquid surface is reached to achieve liquid level detection.

[0041] In this embodiment, there are multiple irradiation positions. The signal entering the prism structure 20 from the entrance and exit surface 21 is emitted from the entrance and exit surface 21 after being reflected by at least two irradiation positions. The irradiation positions in this embodiment are set to two, so that the signal enters the prism structure 20 from the entrance and exit surface 21, forms a path substantially parallel to the entrance and exit surface 21 after being reflected by one irradiation position, and then forms a path substantially perpendicular to the entrance and exit surface 21 and is emitted from the entrance and exit surface 21 after passing through another irradiation position. Of course, the number of irradiation positions can also be set to more, or only one can be set, as long as the signal angle or the position of the detector 10 is adjusted accordingly to achieve signal transmission and reception.

[0042] At the same time, in order to facilitate the emission and reception of signals, according to the actual situation, the entrance and exit surface 21 can be set to one or more. Since there are two irradiation positions in this embodiment, only one entrance and exit surface 21 is set in this embodiment. The detector 10 is set at the entrance and exit surface 21, and the transmitting end 11 and the receiving end 12 are set on the side where the entrance and exit surface 21 is located. Of course, multiple entrance and exit surfaces 21 can also be used. The transmitting end 11 and the receiving end 12 can be located at different entrance and exit surfaces 21 respectively. At this time, one or more detectors 10 can also be set.

[0043] In this embodiment, the prism structure 20 is integrally provided with the sauce bottle. The inner side of the inclined surface 22 has a coating for refraction and reflection. In this way, the prism structure 20 is directly in contact with the sauce in the sauce bottle. After the signal enters the prism structure 20 from the entrance and exit surface 21, it is reflected and refracted at the inclined surface 22, so that the receiving end 12 receives the reflected signal, thereby judging the liquid level of the sauce.

[0044] In this embodiment, the prism structure 20 is located at the inner wall surface of the material bottle, the detector 10 is located outside the wall surface, the side of the prism structure 20 away from the wall surface is the inclined surface 22, the side of the prism structure 20 close to the wall surface is the entrance and exit surface 21, and the position of the prism structure 20 relative to the material bottle is adjustable to change the distance between the prism structure 20 and the material bottle. Specifically, the prism structure 20 of this embodiment is located at the bottom wall surface inside the material bottle, the irradiation position is in contact with the seasoning inside the material bottle, the entrance and exit surface 21 is below the irradiation position, the transmitting end 11 and the receiving end 12 are below the entrance and exit surface 21, and the detector 10 is located outside the material bottle. In this way, the transmitting end 11 emits a signal from bottom to top through the bottom wall surface of the material bottle to the entrance and exit surface 21, the signal continues to be reflected from bottom to top at the irradiation position, the reflected signal is transmitted horizontally to another irradiation position for reflection, and then the signal is transmitted from top to bottom to the entrance and exit surface 21 and received by the receiving end 12. The prism structure 20 is small in size and has a large allowable deviation for the installation of the liquid level detection mechanism. The vertical position of the liquid level detection mechanism in the material bottle can be flexibly adjusted according to the actual situation to achieve the purpose of detecting the required liquid level. Of course, the prism structure 20 can also be set as a split type with the material bottle. For example, a recess can be provided at the bottom of the material bottle so that the prism structure 20 can extend into the material bottle from the recess to detect the liquid level, or the prism structure 20 can also be provided outside the material bottle.

[0045] It should be noted that the detector 10 can be connected to the analog-to-digital conversion port of the single-chip microcomputer. The detector 10 outputs a signal consistent with the liquid level condition, and this signal is connected to the analog-to-digital conversion port of the single-chip microcomputer as the liquid level control signal of the liquid level detection mechanism. When the liquid level submerges the prism structure 20, this signal outputs a low voltage, and when the liquid level is lower than the prism structure 20, this signal is a high voltage.

[0046] The specific structural form of the prism structure 20 can adopt a variety of setting methods, as long as the signal can be incident and emitted at the entrance and exit surface 21 through the inclined surface 22. The following lists several specific structural forms of the prism structure 20.

[0047] Embodiment 1

[0048] Such as Figure 3 、 Figure 4As shown, in this embodiment, the inclined surface 22 extends circumferentially to form an annular conical inclined surface 221. Two circumferentially opposite positions of the annular conical inclined surface 221 are used as irradiation positions. The signal from the transmitting end 11 is reflected by multiple irradiation positions and then emitted to the receiving end 12. Specifically, in this embodiment, the prism structure 20 is a rotating body, the rotating surface is the inclined surface 22, and the entrance and exit surface 21 is arranged at the opening of the rotating surface. The entrance and exit surface 21 is circular and covers the opening of the rotating surface. Thus, when the signal enters the prism structure 20 from any position on the entrance and exit surface 21 except the center of the entrance and exit surface 21, it can form two reflections on the inclined surface 22 and then be emitted from the entrance and exit surface 21. Moreover, the irradiation positions formed by the two reflections are symmetrically arranged along the axis of the prism structure 20. In this way, the signal can form an irradiation position on the inclined surface 22 when entering from any angle along the circumference of the prism structure 20, so that when installing the prism structure 20, there is no need to consider the circumferential position of the prism structure 20, which facilitates the installation of the liquid level detection mechanism.

[0049] In this embodiment, the prism structure 20 includes a conical structure or a frustum-shaped structure. The tip of the conical structure or the end with a smaller diameter of the frustum-shaped structure faces the inside of the sauce bottle. The conical structure or the frustum-shaped structure has an annular conical inclined surface 221. Specifically, the prism structure 20 can be set as Figure 3 the conical structure shown. The tip of the conical structure extends into the sauce bottle, so that the sauce can block or expose the tip of the conical structure, thereby changing the propagation direction of the signal, and then changing the strength of the signal received by the receiving end 12, so as to judge the liquid level of the sauce. The prism structure 20 can also be set as a frustum-shaped structure, that is, a plane is provided at each of the two ends of the inclined surface 22 to form a frustum-shaped structure. The entrance and exit surface 21 is arranged at the end with a larger diameter of the frustum-shaped structure, and a transition surface is arranged at the end with a smaller diameter of the frustum-shaped structure. The transition surface is closer to the inside of the sauce bottle than the entrance and exit surface 21, and the signal emitted by the transmitting end 11 does not pass through the transition surface, and the transition surface does not change the propagation direction of the signal. Optionally, the signal can use an optical signal. According to the different refractive indices of the optical signal in different media, the propagation direction of the optical signal is changed, so that the receiving end 12 can receive optical signals with different strengths, so as to judge whether the sauce submerges the prism structure 20, and then judge the liquid level of the sauce.

[0050] Embodiment 2

[0051] The difference from Embodiment 1 is that the two irradiation positions of the prism structure 20 in this embodiment are not arranged on the same annular conical inclined surface 221, but the first inclined surface 222 and the second inclined surface 223 are arranged, as follows:

[0052] In this embodiment, the inclined surface 22 includes a first inclined surface 222 and a second inclined surface 223. The first inclined surface 222 and the second inclined surface 223 have opposite inclined directions relative to the access surface 21. Both the first inclined surface 222 and the second inclined surface 223 have irradiation positions. The signal from the transmitting end 11 is reflected by the irradiation positions of the first inclined surface 222 and the second inclined surface 223 and then emitted to the receiving end 12. Specifically, the prism structure 20 is a mirror-symmetric structure. The first inclined surface 222 and the second inclined surface 223 are symmetrically arranged along the mirror plane. The transmitting end 11 and the receiving end 12 are also symmetrically arranged along the mirror plane. At the same time, the access surface 21 is also symmetric along the mirror plane. The signal direction emitted by the transmitting end 11 can be directed towards the first inclined surface 222 to ensure that the signal can be reflected for the first time on the first inclined surface 222. After the first reflection, it undergoes a second reflection on the second inclined surface 223, and then is emitted from the access surface 21 to the receiving end 12. At the same time, the signal emitted from the access surface 21 should be directed towards the receiving end 12 to ensure that the receiving end 12 can successfully receive the reflected signal. The reflection order of the signal on the first inclined surface 222 and the second inclined surface 223 can be reversed, that is, the signal direction emitted by the transmitting end 11 can be directed towards the second inclined surface 223. The signal undergoes the first reflection on the second inclined surface 223, then undergoes the second reflection on the first inclined surface 222, and finally is emitted from the access surface 21 to the receiving end 12. In this way, after the signal undergoes two reflections on the first inclined surface 222 and the second inclined surface 223, the emission and incidence of the signal in the prism structure 20 are in the same plane, and the incidence direction and the emission direction of the signal are symmetric with respect to the mirror plane of the prism structure 20, which is beneficial to the installation of the liquid level detection mechanism and convenient for receiving the signal. It should be noted that the positions of the irradiation positions on the first inclined surface 222 and the second inclined surface 223 are symmetric along the mirror plane, and the positions of the irradiation positions on the first inclined surface 222 and the second inclined surface 223 are not fixed. When the position and angle of the signal entering the access surface 21 are different, the positions of the irradiation positions on the first inclined surface 222 and the second inclined surface 223 are also different, and the measured liquid level height is also different. Different liquid level heights can be detected by changing the alignment position of the transmitting end 11 and the access surface 21 and the angle of the transmitted signal.

[0053] In this embodiment, the prism structure 20 includes a prism structure. The prism structure includes a first side surface, a second side surface, and a third side surface that are circumferentially bent and connected. The first side surface and the second side surface serve as the first inclined surface 222 and the second inclined surface 223 respectively, and the third side surface serves as the access surface 21. Specifically, as Figure 5 , Figure 6As shown, the prism structure is a triangular prism, and the first side, the second side, and the third side are bent and connected in sequence to form the three sides of the triangular prism. The first side and the second side are symmetrically arranged, and the two bottom surfaces of the triangular prism form two isosceles triangles of equal size. In this way, the signal enters from the third side to the irradiation position on the first side, is reflected to the second side, then undergoes a second reflection on the second side, and finally exits from the third side. Of course, the prism structure 20 can also be set as a pyramid structure, which can also complete the entry, exit, and reflection of the signal. Different from the prism structure, the pyramid structure only has one isosceles triangle bottom surface.

[0054] Embodiment 3

[0055] Different from Embodiment 2, in this embodiment, the prism structure 20 has, in addition to the first side, the second side, and the third side, a fourth side 224, which is specifically as follows:

[0056] In this embodiment, the circumferential direction of the prism structure further includes a fourth side 224, which is located between the first side and the second side, and the size of the fourth side 224 is smaller than that of the third side. Specifically, as Figure 7 、 Figure 8 shown, the prism structure is a quadrangular prism, and the first side, the fourth side 224, the second side, and the third side are bent and connected in sequence to form the four sides of the quadrangular prism. The first side and the second side are symmetrically arranged, thus forming an isosceles quadrangular prism. In this way, the signal enters from the third side to the irradiation position on the first side, is reflected to the second side, then undergoes a second reflection on the second side, and finally exits from the third side. The fourth side 224 is smaller and will not block the signal, so it does not affect the propagation direction of the signal.

[0057] Embodiment 4

[0058] Different from Embodiment 3, in this embodiment, in addition to the quadrangular prism structure, the prism structure 20 also has an extension part 225 connected to the quadrangular prism, which is specifically as follows:

[0059] In this embodiment, the prism structure 20 further includes a prism-shaped extension part 225, and the circumferential side surface of the extension part 225 is connected to the third side. Specifically, as Figure 9 、 Figure 10As shown, the prism structure 20 is set as a hexagonal prism. That is, on the basis of the quadrangular prism in Embodiment 3, a cuboid, namely an extension part 225, with the same height as the quadrangular prism in Embodiment 3 is added, and one side surface of the cuboid is set to coincide with the third side surface of the quadrangular prism in Embodiment 3, thereby forming a hexagonal prism. Thus, one surface of the cuboid far from the third side surface of the quadrangular prism becomes the third side surface of the hexagonal prism, that is, the signal input / output surface 21. In this way, the signal is incident from the third side surface of the hexagonal prism into the first side surface and reflected to the second side surface. After the signal is reflected from the second side surface, it finally exits from the third side surface of the hexagonal prism, thereby sending the signal to the receiving end 12. During the signal transmission, the signal does not pass through the fourth side surface 224 and the two side surfaces of the extension part 225 perpendicular to the third side surface. Therefore, the signal is not affected by these three side surfaces, and the transmission direction of the signal is still the same as that of the above-mentioned quadrangular prism. When the liquid level detection mechanism is arranged at the bottom of the bottle, the extension part 225 is located below the first side surface and the second side surface, and the transmitting end 11 and the receiving end 12 are arranged below the extension part 225. Therefore, the setting of the extension part 225 increases the distance between the input / output surface 21 and the first side surface and the second side surface, enabling the liquid level detection mechanism to measure a higher liquid level. By adjusting the size of the extension part 225, the liquid level detection mechanism can detect different liquid levels. Of course, the extension part 225 can also be set into other structures such as a hexagonal prism or an octagonal prism, as long as other parts of the extension part 225 do not block the signal transmission path except that the third side surface serves as the input / output surface 21 for signal input and output.

[0060] Embodiment 5

[0061] The difference from Embodiment 2 is that the surface perpendicular to the first side surface of the prism structure 20 in this embodiment is not an isosceles triangle but a cylindrical surface, specifically as follows:

[0062] As Figure 11 、 Figure 12 shown, in this embodiment, the prism structure 20 includes a columnar structure. The columnar structure is a symmetric structure. The two bottom surfaces of the columnar structure are the first bottom surface and the second bottom surface respectively. The first bottom surface serves as the input / output surface 21. There are notches at the circumferentially opposite positions of the columnar structure, and the notches extend to the second bottom surface of the columnar structure. The notches form a first inclined surface 222 and a second inclined surface 223 as the two inclined surfaces 22 of the signal. The first inclined surface 222 and the second inclined surface 223 are symmetrically arranged on both sides of the symmetry plane of the columnar structure. The edge lines where the first inclined surface 222 and the second inclined surface 223 intersect with the circumferential side surface of the column are arcs. The first inclined surface 222 and the second inclined surface 223 intersect with the second bottom surface at the same straight line. At this time, the second bottom surface disappears. In this way, the signal is incident from the input / output surface 21 into the columnar structure and exits from the input / output surface 21 after being reflected by the first inclined surface 222 and the second inclined surface 223.

[0063] Embodiment 6

[0064] Different from the fifth embodiment, the first inclined surface 222 and the second inclined surface 223 in this embodiment do not intersect. Instead, the first inclined surface 222 and the second inclined surface 223 respectively intersect with the second bottom surface, specifically as follows:

[0065] As Figure 13 , Figure 14 shown, in this embodiment, the columnar structure further has an intermediate surface 226 located between the first inclined surface 222 and the second inclined surface 223, and the intermediate surface 226 is the end surface of the columnar structure. Specifically, the intermediate surface 226 is the second bottom surface in the fifth embodiment. In this embodiment, the first inclined surface 222 intersects with the second bottom surface at a straight line, and the second inclined surface 223 intersects with the second bottom surface at another straight line. These two straight lines are parallel, thus forming the intermediate surface 226 on the second bottom surface. When the signal is transmitted within the prism structure 20, the signal does not pass through the intermediate surface 226, and the intermediate surface 226 does not affect the transmission of the signal.

[0066] It should be noted that the "multiple" in the above embodiments refers to at least two.

[0067] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0068] 1. Solved the problem of inaccurate detection of the liquid level of seasonings in the prior art;

[0069] 2. Set the prism structure so that the signal is emitted to the receiving end after multiple reflections at the irradiation position, thereby judging the liquid level of the seasonings in the bottle according to the different signals received by the receiving end;

[0070] 3. This setting method has high reliability and accurate liquid level judgment. Even if there is a situation where the surface of the liquid level detection mechanism is slightly blocked by a little seasoning due to seasoning splashing, it will not affect the function of the liquid level detection mechanism, has a long service life, and the size of the liquid level detection mechanism is small and will not occupy too much volume of the bottle.
