Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a liquid heater with reliable positioning. Background Art

[0002] With the advancement of science and technology, the anti-overflow detection method currently used in kitchen appliances is mainly detection plate detection. For example, the applicant previously applied for a patent with application number 201720526032.4, disclosing a food processor with good anti-overflow effect, including a base with a built-in motor and a mixing cup arranged above the base, the mixing cup including a glass cup with a handle and a water level detection structure arranged on the outer side of the glass cup, the water level detection structure including a detection component fitted on the outer wall of the glass cup and a capacitive sensing plate connected to the detection component, a handle shell is sleeved on the handle, the handle shell includes an arc-shaped cavity matching the handle and a positioning groove for embedding the capacitive sensing plate, the capacitive sensing plate is positioned at a preset station adjacent to the outer wall of the glass cup through the handle shell, and then, a waterproof film is added between the handle shell and the glass cup to prevent the capacitive sensing plate from short-circuiting due to water entering.

[0003] During further research, the applicant discovered that since the outer wall of a glass is generally curved and the sensor plate is a strip-shaped flat plate, if the sensor plate is directly positioned on the smooth outer wall of the glass through the handle shell, the sensor plate will be difficult to position and will slide relative to the cup body, resulting in inaccurate assembly position of the sensor plate and affecting detection accuracy.

[0004] Moreover, the glass cups currently used for air detection are usually stretched tubular glass cups. The wall thickness of the tubular glass cup is small, which can reduce the air distance of the sensor plate. However, due to the small wall thickness of the glass cup, it is necessary to rely on other mounting structures such as the handle shell to install and position the sensor plate. On the one hand, this makes the assembly process complicated, and the positioning of the sensor plate and the glass cup difficult, and the fit cannot be guaranteed, which affects the detection accuracy. On the other hand, due to installation errors between the handle shell and the glass cup during the assembly process, when the detection plate is positioned using the handle shell, the relative position between the detection plate and the glass cup becomes inaccurate in assembly, the positioning of the detection plate deviates, and there is a deviation between the water level actually detected by the detection plate and the preset water level, resulting in inaccurate detection. Utility Model Content

[0005] The utility model provides a liquid heater with reliable positioning, which adopts a more direct positioning method to achieve reliable positioning between the detection plate and the glass cup body, so as to solve the problem of inaccurate installation position caused by the detection plate sliding relative to the glass cup body during installation in the prior art, thereby improving assembly convenience and detection accuracy.

[0006] The technical solution adopted by the utility model is:

[0007] The utility model provides a liquid heater with reliable positioning, comprising a glass cup body and a strip-shaped detection plate for detecting liquid level in the air, wherein the detection plate is vertically installed on the peripheral wall of the glass cup body, a positioning hole is arranged on the peripheral wall of the glass cup body, and the detection plate is provided with a positioning column protruding toward the glass cup body, and the positioning column is inserted into the positioning hole so that the detection plate is positioned on the peripheral wall of the glass cup body.

[0008] The utility model provides a liquid heater with reliable positioning. A positioning hole is set on the peripheral wall of the glass cup body, and a positioning column is set on the detection plate. The positioning column is inserted into the positioning hole so that the detection plate is positioned on the peripheral wall of the glass cup body. Therefore, there is no need to use additional tooling to position the detection plate, which can not only reduce the possibility of error accumulation, but also save the use of auxiliary parts, simplify the assembly steps, improve assembly efficiency, and solve the problem of inaccurate installation position caused by sliding of the detection plate with the glass cup body during installation, thereby improving the accuracy of the installation of the detection plate and thus improving the detection accuracy; on the other hand, the relative position of the positioning column and the positioning hole is unique, so that the detection plate can be accurately aligned and the detection is accurate. In the case of shaking of the glass cup body, the positioning column and the positioning hole limit cooperation can effectively reduce the displacement of the detection plate caused by vibration during work, ensure the consistency of the detection result, improve the detection accuracy, and, in the case that the detection plate is damaged and needs multiple assembly and repair, the detection plate can still accurately return to its original position, thereby ensuring the quality of the product and the stability of performance.

[0009] In a preferred embodiment, the positioning hole is arranged through the peripheral wall of the glass cup body, the positioning post is sealingly matched with the positioning hole, and the positioning post is a detection probe extending from the positioning hole into the glass cup body.

[0010] By inserting the positioning hole through the peripheral wall of the glass cup body and making the positioning post and the positioning hole seal and fit, the fitting length of the positioning post and the positioning hole can be extended, thereby improving the positioning reliability between the detection plate and the glass cup body. At the same time, the positioning post is a detection probe, and the positioning post realizes dual functions, which not only plays the role of positioning the detection plate, but also can be used as a detection probe to detect the internal environment of the glass cup body. At the same time, the detection board can also realize basic detection functions. Therefore, the detection board assembly realizes functional integration, reduces the number of parts, simplifies the product structure, reduces costs, and makes detection more comprehensive. In addition, it also saves the need to set up additional holes on the glass cup body to install the detection probe, simplifies the processing technology, and reduces production costs.

[0011] In a preferred embodiment, the detection board includes a capacitor electrode for sensing the liquid level in the air and a processing chip electrically connected to the capacitor electrode, and the detection probe is electrically connected to the processing chip.

[0012] By setting capacitor electrodes and processing chips on the detection board, the detection board is independently produced to complete detection and signal processing, with a high degree of functional integration. At the same time, the detection probe is electrically connected to the processing chip to achieve compatibility of the detection board with the detection signal of the detection probe, simplifying the structure and further realizing the functional diversification of the detection board.

The front end of the detection board extends into the glass cup body to realize detection, and the rear end is connected to the lead wire to realize signal transmission, avoiding signal interference between the detection probe and the capacitor electrode on the detection board, and ensuring accurate detection.

[0015] In a preferred embodiment, the detection probe includes a temperature probe for detecting the temperature of the liquid inside the glass cup body; or, the detection probe includes a water level probe; or, the detection probe includes an anti-overflow probe for anti-overflow detection, and the anti-overflow probe is arranged on the upper part of the detection plate.

[0016] The detection probe includes a temperature probe, which can detect the temperature of the liquid inside the glass cup body;

[0017] The detection probe is a water level probe. In one case, the water level probe can be used to simply detect the water level to prevent the glass cup from drying out. The detection board omits the water level detection and only realizes the overflow prevention detection. In another case, the water level probe is used for water level detection. At the same time, the detection board is also provided with a water level capacitor electrode for water level detection. The water level detection of the water level probe and the detection board realizes double detection to correct the inaccurate detection of the detection board or the water temperature probe, and realizes accurate detection.

[0018] The detection board includes an anti-overflow probe, which is arranged on the upper part of the detection board to realize anti-overflow detection. In one case, the anti-overflow probe is used to perform anti-overflow detection, and the detection board omits the anti-overflow detection and only realizes water level detection. In another case, an anti-overflow capacitor electrode for anti-overflow detection is also provided on the detection board. The anti-overflow probe and the detection board can be used to perform double anti-overflow detection to correct inaccurate detection of the detection board or the anti-overflow probe and realize accurate detection.

[0019] In a preferred embodiment, the positioning hole is set through the peripheral wall of the glass cup body, the positioning column is sealed and cooperated with the positioning hole, and the positioning column is a nozzle set through the detection plate, the front end of the nozzle extends into the glass cup body, and the rear end of the nozzle is connected to the supply device, and the supply device supplies the medium into the glass cup body through the nozzle.

[0020] The positioning column is a nozzle, which plays a dual role. It can not only play the role of positioning the detection plate, but also play the role of supplying medium into the glass cup body, avoiding the need for additional perforations on the glass cup body, simplifying the processing technology and simplifying the structure.

[0021] In a preferred embodiment, the supply device comprises a water supply device;

[0022] Alternatively, the supply device comprises a gas supply device;

[0023] Alternatively, the supply device comprises a steam generating device.

[0024] The supply device includes a water supply device, which can automatically supply water to the inside of the glass cup body, which can be used to prepare soy milk, boil it, and clean the glass cup body, which is convenient to use. The supply device includes an air supply device, which can be used to dry the cup body after processing or cool the liquid in the glass cup body for user use, etc. For example, when corresponding to the pulping program in the food processor, the soy milk can be cooled to facilitate direct drinking by the user, thereby improving the user experience. The supply device includes a steam generating device, which can supply steam to the glass cup body, adjust the air pressure inside and outside the cup body, and can also use hot steam to heat the pulp in the pulping scenario of the food processor.

[0025] In a preferred embodiment, a sealing member is sleeved on the outer side of the positioning column, and the sealing member seals the positioning hole.

[0026] By sleeved a seal on the outside of the positioning column, the seal is used to seal the positioning hole to prevent the liquid inside the glass cup from flowing out and to prevent damage to the detection plate. The seal is sleeved on the outside of the positioning column and cooperates with the positioning hole as the positioning column is installed, so that the seal is reliable.

[0027] In a preferred embodiment, the outer side of the detection plate is wrapped with a silicone member, and the silicone member and the sealing member are integrally formed.

[0028] By wrapping the silicone part on the outside of the detection plate, the detection plate is protected, and flexible contact between the detection plate and the glass cup body or the handle is achieved, which avoids the detection plate from being damaged by bumps and ensures effective detection. The silicone part and the seal are integrally formed, so that the connection between the seal and the silicone part is reliable, which avoids the seal from loosening and improves the sealing effect.

[0029] In a preferred embodiment, the positioning hole is a blind hole;

[0030] By setting the positioning hole as a blind hole, while achieving reliable positioning of the detection plate and the glass cup body, perforating the glass cup body can be avoided, thereby maintaining the structural integrity of the inner wall of the glass cup body and eliminating the trouble of sealing and waterproofing the perforations, which is conducive to the smoothness of the inner side of the glass cup body and easy cleaning.

[0031] In a preferred embodiment, the liquid heater further comprises a positioning bracket fixed to the outside of the glass body, and the positioning bracket presses the detection plate against the peripheral wall of the glass body.

[0032] By setting a positioning bracket and using the positioning bracket to press the detection plate against the peripheral wall of the glass cup body, the positioning column and the positioning hole can be plugged in and matched more reliably, the positioning of the detection plate is more reliable, and the displacement of the detection plate causing inaccurate detection is avoided, thereby improving the detection accuracy.

DETAILED DESCRIPTION

[0045] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

[0049] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0050] like Figure 1-5 As shown, the utility model provides a liquid heater with reliable positioning, including a glass cup body 10 and a strip-shaped detection plate 20 for detecting the liquid level in the air, the detection plate 20 is vertically installed on the peripheral wall of the glass cup body 10, the peripheral wall of the glass cup body 10 is provided with a positioning hole 11, the detection plate 20 is provided with a positioning column 30 protruding toward the glass cup body 10, the positioning column 30 is inserted into the positioning hole 11, so that the detection plate 20 is positioned on the peripheral wall of the glass cup body 10.

[0051] The liquid heater provided by the utility model has reliable positioning, by arranging the positioning hole 11 on the peripheral wall of the glass cup body 10, arranging the positioning post 30 on the detection plate 20, and inserting the positioning post 30 into the positioning hole 11 so that the detection plate 20 is positioned on the peripheral wall of the glass cup body 10, thereby eliminating the need to use additional tooling to position the detection plate 20, which can not only reduce the possibility of error accumulation, but also eliminate the use of auxiliary parts, simplify the assembly steps, improve the assembly efficiency, solve the problem of inaccurate installation position caused by the sliding of the detection plate 20 with the glass cup body 10 during the installation process, and improve the positioning of the detection plate 20 The accuracy of installation is improved, thereby improving the detection accuracy; on the other hand, the relative positions of the positioning column 30 and the positioning hole 11 are unique, so that the detection plate 20 can be accurately aligned and the detection is accurate. When the glass cup body 10 shakes, the positioning column 30 and the positioning hole 11 limit the cooperation, which effectively reduces the displacement of the detection plate 20 caused by vibration during operation, ensures the consistency of the detection results, improves the detection accuracy, and, when the detection plate 20 is damaged and requires multiple assembly and repair, the detection plate 20 can still accurately return to its original position, ensuring the quality of the product and the stability of its performance.

[0052] It should be noted that the present invention does not limit the specific structure of the positioning column 30. For example:

[0053] Implementation example 1, such as Figure 1-5As shown, the positioning hole 11 is set through the peripheral wall of the glass cup body 10, the positioning column 30 is sealed with the positioning hole 11, and the positioning column 30 is a detection probe 31 extending from the positioning hole 11 into the glass cup body 10.

[0054] More preferably, in this implementation example, Figure 4 , 5 As shown, the detection board 20 includes a capacitor electrode 201 for sensing the liquid level in the air and a processing chip 202 electrically connected to the capacitor electrode 201, and the detection probe 31 is electrically connected to the processing chip 202. Specifically, in order to achieve reliable fixation of the detection board 20 and the detection probe 31, a mounting groove is provided on the side of the detection board 20 facing the glass cup body 10, and the detection probe 31 is fixed in the mounting groove. The lead of the detection probe 31 is printed on the surface of the detection board 20 and is electrically connected to the processing chip.

[0055] In this embodiment, the detection probe 31 is a temperature probe for detecting the temperature of the liquid inside the glass cup body 10. The capacitor electrode includes a water level capacitor electrode and an anti-overflow capacitor electrode. The water level capacitor electrode is located below the anti-overflow capacitor electrode. Multiple anti-overflow capacitor electrodes are provided to achieve anti-overflow detection at different heights.

[0056] Of course, the structure of the detection board 20 is not limited to the above one. In fact, the detection board 20 can only set a water level capacitor electrode separately or set an anti-overflow capacitor electrode separately, or set an anti-overflow capacitor electrode and a water level capacitor electrode. The above structure of the detection board 20 is still applicable to other implementation examples.

[0057] This embodiment extends the matching length of the positioning post 30 and the positioning hole 11 by passing the positioning hole 11 through the peripheral wall of the glass cup body 10 and making the positioning post 30 and the positioning hole 11 seal and fit, thereby improving the positioning reliability between the detection plate 20 and the glass cup body 10. At the same time, the positioning post 30 is a detection probe 31, and the positioning post 30 realizes a dual function, which not only plays the role of positioning the detection plate 20, but also can be used as a detection probe 31 to detect the internal environment of the glass cup body 10. At the same time, the detection board 20 can also realize basic detection functions. Therefore, the detection board 20 assembly realizes functional integration, reduces the number of parts, simplifies the product structure, reduces costs, and makes detection more comprehensive. In addition, it is also unnecessary to set up another perforation on the glass cup body 10 to install the detection probe 31, which simplifies the processing technology and reduces production costs. By setting capacitor electrodes and processing chips on the detection board 20, the detection board 20 is independently produced to complete detection and signal processing, with a high degree of functional integration. At the same time, the detection probe 31 is electrically connected to the processing chip, so that the detection board 20 is compatible with processing the detection signal of the detection probe 31, simplifying the structure and further realizing the functional diversification of the detection board 20.

[0058] In addition, if Figure 3As shown, the sealing method of the positioning hole 11 is preferably that a sealing member 40 is sleeved on the outer side of the positioning column 30, and the sealing member 40 seals the positioning hole 11. More preferably, a silicone member 50 is wrapped on the outer side of the detection board 20, and the silicone member 50 is integrally formed with the sealing member 40. Of course, the above sealing method is still applicable to other implementation examples.

[0059] In this embodiment, a seal 40 is mounted on the outside of the positioning column 30, and the positioning hole 11 is sealed by the seal 40 to prevent the liquid inside the glass cup body 10 from flowing out and to prevent the detection board 20 from being damaged. The seal 40 is mounted on the outside of the positioning column 30, and the seal 40 cooperates with the positioning hole 11 as the positioning column 30 is installed, so that the seal is reliable. By wrapping the silicone member 50 on the outside of the detection board 20, the detection board 20 is protected, and flexible contact between the detection board 20 and the glass cup body 10 or the handle 60 is achieved, so that the detection board 20 is prevented from being damaged by collision, and effective detection is ensured. The silicone member 50 and the seal 40 are integrally formed, so that the connection between the seal 40 and the silicone member 50 is reliable, and the seal 40 is prevented from loosening, thereby improving the sealing effect.

[0060] More preferably, in this implementation example, Figure 3 As shown, a hook portion 51 is provided on the upper part of the silicone member 50, and the handle 60 presses the silicone member 50 to fix the detection plate 20 on the outer wall of the glass cup body 10. Of course, the utility model does not limit the fixing method of the detection plate 20. In other preferred implementation examples, a positioning bracket can also be used for fixing. For example, the liquid heater also includes a positioning bracket fixed on the outside of the glass cup body 10, and the positioning bracket presses the detection plate 20 against the peripheral wall of the glass cup body 10. The detection plate 20 is fixed by injecting glue between the positioning bracket and the glass cup body 10. The positioning bracket can be an independently set tool or a handle 60.

[0061] By setting a positioning bracket and using the positioning bracket to press the detection plate 20 against the peripheral wall of the glass cup body 10, the insertion and fit between the positioning column 30 and the positioning hole 11 are more reliable, and the positioning of the detection plate 20 is more reliable, thereby avoiding the displacement of the detection plate 20 and causing inaccurate detection, thereby improving the detection accuracy. Of course, the above-mentioned method of fixing the detection plate 20 can be applied to other implementation examples.

[0062] It can be understood that the detection probe 31 in this embodiment is not limited to the use of a temperature probe. In fact, in this embodiment and other embodiments, the detection probe 31 may include one or more of a temperature probe, a water level probe, and an anti-overflow probe. For example, multiple detection probes 31 may be optionally arranged on the detection board 20, and the multiple detection probes 31 are respectively temperature probes, water level probes, or anti-overflow probes.

[0063] It should be further explained that when the detection probe 31 is a water level probe, in one embodiment, the water level probe can be used to simply detect the water level to prevent the glass cup body 10 from drying out, and the water level detection capacitor electrode is omitted on the detection board 20, and only the overflow prevention detection is realized; in another embodiment, the water level probe performs water level detection, and at the same time, a water level capacitor electrode is also provided on the detection board 20, and the water level probe and the water level capacitor electrode of the detection board 20 realize double detection, the water level probe is used for contact detection of the water level, and the water level capacitor electrode is used for remote detection of the water level, so as to correct the inaccurate detection of the detection board 20 or the water temperature probe, and realize accurate detection;

[0064] Similarly, when the detection plate 20 is an anti-overflow probe, the anti-overflow probe is arranged on the upper part of the detection plate 20 to realize anti-overflow detection. In one embodiment, the anti-overflow probe is used for anti-overflow detection, and the detection plate 20 omits the anti-overflow capacitor electrode to only realize water level detection. In another embodiment, the anti-overflow probe is used for contact detection of anti-overflow signals, and an anti-overflow capacitor electrode is also arranged on the detection plate 20 for air anti-overflow detection. The anti-overflow probe and the detection plate 20 can be used for double anti-overflow detection to correct the inaccurate detection of the detection plate 20 or the anti-overflow probe and realize accurate detection.

[0065] Optionally, in this embodiment, the positioning post 30 protrudes from the inner surface of the glass body 10 to fully contact the liquid for accurate detection. Of course, considering the problem of cleaning dead angles, if the wall thickness of the glass body 10 is sufficient, the inner end of the positioning post 30 can also be made flush with the inner surface of the glass body 10 to avoid the generation of cleaning dead angles and facilitate thorough cleaning.

[0066] Implementation Example 2, such as Figure 6 As shown, what is different from Implementation Example 1 is that in this implementation example, the detection plate 20 is provided with a mounting hole 21, the detection probe 31 is passed through the mounting hole 21, the front end of the detection probe 31 extends into the glass cup body 10, and the rear end of the detection probe 31 is connected to the lead wire 311.

[0067] By setting the mounting hole 21 on the detection board 20, the detection probe 31 is inserted into the mounting hole 21, which facilitates the fixed connection between the detection probe 31 and the detection board 20 and the reliable fixing method. The front end of the detection board 20 extends into the glass cup body 10 to realize detection, and the rear end is connected to the lead-out line 311 to realize signal transmission, avoiding signal interference between the detection probe 31 and the capacitor electrode on the detection board 20, and the detection is accurate.

[0068] Implementation Example 3, such as Figure 7-8As shown, what is different from Implementation Example 1 is that in this implementation example, a positioning hole 11 is arranged through the peripheral wall of the glass cup body 10, a positioning column 30 is sealed with the positioning hole 11, and the positioning column 30 is a nozzle 32 arranged through the detection plate 20, a front end of the nozzle 32 extends into the glass cup body 10, and a rear end of the nozzle 32 is connected to a supply device, and the supply device supplies the medium into the glass cup body 10 through the nozzle 32.

[0069] More preferably, the supply device is one or more of a water supply device, an air supply device, and a steam generating device. The water supply device includes a water pump and a water tank; the air supply device includes an air pump.

[0070] In this embodiment, the positioning column 30 is a nozzle 32, which plays a dual role. It can not only play the role of positioning the detection plate 20, but also play the role of supplying medium into the glass cup body 10, avoiding the need for additional perforations on the glass cup body 10, thereby simplifying the processing technology and simplifying the structure.

[0071] The supply device includes a water supply device, which can automatically supply water to the inside of the glass cup body 10, which can be used to prepare soy milk, boil it, and clean the glass cup body 10, and is convenient to use.

[0072] The supply device includes an air supply device, which can be used to dry the cup body after processing or cool the liquid in the glass cup body 10 for use by the user, etc. For example, when corresponding to the pulping program in the food processor, the soy milk can be cooled to facilitate direct drinking by the user, thereby improving the user experience. The supply device includes a steam generating device, which can supply steam into the glass cup body 10 to adjust the air pressure inside and outside the cup body, and can also use hot steam to heat the pulp when corresponding to the pulping scene of the food processor.

[0073] It should also be noted that the present invention does not limit the shape and number of the positioning posts 30, for example:

[0074] In implementation examples 1, 2, and 3, refer to Figure 4 As shown, the positioning post 30 can be cylindrical, and the positioning hole 11 can be a circular hole. One positioning post 30 is provided, and one positioning hole 11 is provided.

[0075] Implementation Example 4, such as Fig. 9 As shown, the positioning post 30 may be a square post, the positioning hole 11 may be a square hole, one positioning post 30 is provided, and one positioning hole 11 is provided. In this arrangement, when only one positioning post 30 is provided, the positioning post 30 is inserted into the positioning hole 11 and then engages with the positioning hole 11 to prevent the detection plate 20 from rotating.

[0076] Of course, the positioning column 30 may also have an irregular shape, for example, a spline groove or a flat portion may be provided on the surface of the positioning column 30 to achieve a non-rotational fit between the positioning column 30 and the positioning hole 11 .

[0077] Implementation Example 5, such as Fig.10 As shown, at least two positioning posts 30 are provided on the detection plate 20, and the glass body 10 is provided with positioning holes 11 matching the number of the positioning posts 30 to prevent the detection plate 20 from rotating. The specific functions and effects of the positioning posts 30 are not described here.

[0078] In the above-mentioned implementation example of the utility model, the glass cup body 10 can be optionally stretch-formed to make the cup wall of the glass cup body 10 thinner, and a perforation is set in the cup wall of the glass cup body 10 to achieve reliable cooperation between the positioning column 30 and the positioning hole 11. Of course, in fact, in other embodiments, the positioning hole 11 can not only adopt the perforated structure in the above-mentioned implementation example, but also adopt a blind hole structure. For example, the glass cup body 10 is die-cast and has sufficient wall thickness. A blind hole is set in the cup wall of the glass cup body 10 to realize the positioning of the positioning column 30.

[0079] By setting the positioning hole 11 as a blind hole, on the premise of achieving reliable positioning of the detection plate 20 and the glass cup body 10, perforating the glass cup body 10 can be avoided, thereby maintaining the structural integrity of the inner wall of the glass cup body 10 and eliminating the trouble of sealing and waterproofing the perforations, which is beneficial to the smoothness of the inner side of the glass cup body 10 and convenient for cleaning.
