Description

Technical Field

[0001] The present application belongs to the technical field of steam wands, and in particular relates to a steam wand and a beverage processing device. Background Art

[0002] When preparing certain beverages, beverage processing equipment requires the beverage to be maintained within a specific temperature range. For example, when using a steam wand to make milk foam, the most suitable whipping temperature is about 50 to 60 degrees Celsius. Once the temperature exceeds 80 degrees Celsius, the milk foam will be over-whipped, causing the milk foam and milk to separate into layers, resulting in a latte art effect that cannot flow. Therefore, it is necessary to detect the temperature of the beverage.

[0003] The commonly used temperature detection method on the market is to install a temperature sensor at the bottom of the cup holder, and the temperature sensor contacts the bottom of the container containing the beverage, thereby indirectly detecting the temperature of the beverage. Since this method detects the temperature of the container, the detection accuracy is poor.

[0004] Therefore, how to accurately detect the temperature of a beverage becomes a problem that needs to be solved in the art. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0040] In the related art, a common method for detecting the temperature of beverages is to install a temperature sensor at the bottom of the cup holder, which contacts the bottom of the container holding the beverage, thereby indirectly detecting the temperature of the beverage. Since this method detects the temperature of the container, the detection accuracy is poor. Some beverage processing equipment sets a temperature sensor on the steam pipe, which directly contacts the beverage, so the temperature measurement is more accurate. However, the setting of the temperature sensor will cause the outer diameter of the steam pipe to be significantly thickened, affecting the milk frothing operation.

[0041] The embodiments of the present application provide a steam wand and a beverage processing device, which can to a certain extent solve the technical problem that in order to accurately detect the temperature of the beverage, a temperature sensor is set on the steam pipe, which causes the outer diameter of the steam pipe to be significantly thickened, thereby affecting the milk frothing operation.

[0042] In a first aspect of the present application, a steam wand is provided. Figure 1 , Figure 2 and Figure 3 , shows a full cross-sectional structural diagram of the steam wand 100. The steam wand 100 includes a steam pipe 110, a steam channel 120, a nozzle 130, a nozzle sleeve 140, and a temperature sensor 150. The steam channel 120 is located in the tube cavity of the steam pipe 110 for steam circulation. The nozzle 130 is connected to the steam channel 120, and the nozzle 130 can be connected to the outlet end of the steam channel 120 to communicate with the steam channel 120; or, the nozzle 130 can be connected to one end of the steam pipe 110 close to the outlet end of the steam channel 120, and the nozzle 130 has no physical connection with the steam channel 120 and is only connected to the steam channel 120. The nozzle sleeve 140 is sleeved outside the nozzle 130, and the nozzle sleeve 140 is connected to the steam pipe 110. The temperature sensor 150 is mounted on the nozzle sleeve 140 , and a detection end of the temperature sensor 150 extends out of the nozzle sleeve 140 , and a wire harness 151 of the temperature sensor 150 extends into a region between the steam pipe 110 and the steam channel 120 .

[0043] The steam wand 100 is used to inject steam into the beverage in the container to change the characteristics of the beverage, such as using the steam wand 100 to make milk foam, using the steam wand 100 to heat the beverage, etc. The steam wand 100 includes a steam channel 120 and a steam pipe 110. The steam channel 120 is used for steam circulation. The steam channel 120 is arranged in the tube cavity of the steam pipe 110 so that the steam wand 100 forms a double-layer structure. Since the steam in the steam wand 100 is a high-temperature gas, the steam channel 120 will have a high temperature. In order to prevent the operator from directly contacting the outer wall of the steam channel 120 and causing scalding, a double-layer steam wand 100 is adopted, so that the steam channel 120 is covered inside by the steam pipe 110, so that the operator is prevented from directly contacting the steam channel 120, thereby reducing the risk of scalding. In addition, a certain interval is set between the steam channel 120 and the cavity wall of the steam pipe 110, and the interval can also further play a role of heat insulation, thereby further reducing the risk of scalding.

[0044] The nozzle 130 can make the steam wand 100 spray steam better. The nozzle 130 can be directly connected to the outlet end of the steam channel 120, or it can be connected to one end of the steam pipe 110, and the nozzle 130 is connected to the steam channel 120. Both can achieve the arrangement of the nozzle 130 at the outlet end of the steam wand 100, so that the steam in the steam channel 120 is sprayed out through the nozzle 130, thereby improving the effect of the steam spraying of the steam wand 100 through the nozzle 130. When the steam wand 100 is used to spray steam into the beverage, it is usually necessary to immerse the nozzle 130 (the outlet end of the steam wand 100) into the beverage to ensure the steam spraying effect. Taking the use of the steam wand 100 to make milk foam as an example, it is necessary to set the steam wand 100 at a certain angle to the liquid surface of the milk, and make the nozzle 130 not completely immersed in the milk, so that the milk and air are fully mixed to form milk foam.

[0045] When using the steam wand 100 to prepare certain beverages, the beverages are required to be maintained within a specific temperature range. The steam sprayed by the steam wand 100 is high-temperature gas, which will heat the beverages. Therefore, a temperature sensor 150 is provided on the steam wand 100. When the steam wand 100 sprays steam into the beverage, the temperature sensor 150 is extended into the beverage to detect the temperature of the beverage. The operator can control the steam spraying amount of the steam wand 100 according to the temperature detected by the temperature sensor 150 to prevent the temperature of the beverage from exceeding a specific range.

[0046] The nozzle sleeve 140 is used to install the temperature sensor 150. The nozzle sleeve 140 is connected to the steam pipe 110. The nozzle sleeve 140 can be welded, bonded, or connected to the end of the steam pipe 110 by threaded fasteners. In some embodiments, the nozzle sleeve 140 can be sleeved on the outside of the steam pipe 110, or the nozzle sleeve 140 can be inserted into the inside of the steam pipe 110 and located between the steam channel 120 and the steam pipe 110. The nozzle sleeve 140 can be connected to the steam pipe 110 by welding, bonding, screwing, or fasteners. The specific installation method of the nozzle sleeve 140 is not limited in this application. Please refer to Figure 1 In some embodiments, the nozzle sleeve 140 is sleeved on the outside of the steam pipe 110, and the two are fixed by pins.

[0047] The detection end of the temperature sensor 150 extends out of the nozzle sleeve 140, so that the temperature sensor 150 is arranged at the outlet end of the steam wand 100 through the nozzle sleeve 140, so that the temperature sensor 150 can be immersed in the beverage together with the steam wand 100 to directly measure the temperature of the beverage. By sleeve-mounting the nozzle sleeve 140 outside the nozzle 130, the temperature sensor 150 installed on the nozzle sleeve 140 is close to the nozzle 130, and the temperature sensor 150 and the nozzle 130 are spaced apart, which can reduce the influence of the nozzle 130 on the detection accuracy of the temperature sensor 150.

[0048] In addition, since there is a certain gap between the steam channel 120 and the cavity wall of the steam pipe 110, the wiring harness 151 of the temperature sensor 150 is extended into the gap to realize the routing of the wiring harness 151 through the gap. This not only avoids occupying additional space and increasing the pipe diameter of the steam rod 100, thereby not affecting the operation of the steam rod 100, but also can protect the wiring harness 151 through the steam pipe 110 to prevent the wiring harness 151 from being damaged by external forces.

[0049] See also Figure 2 In some embodiments, the steam pipe 110 is provided with a wire hole 111, and the nozzle sleeve 140 is sleeved outside the steam pipe 110 and covers the wire hole 111. The wire harness 151 of the temperature sensor 150 extends between the nozzle sleeve 140 and the steam pipe 110, and after reaching the wire hole 111, it extends into the steam pipe 110 through the wire hole 111, extends between the steam channel 120 and the steam pipe 110, and finally enters the inside of the device equipped with the steam wand 100, so that the wire harness 151 of the temperature sensor 150 will never be exposed to the outside. In addition, since the end of the wire harness 151 of the temperature sensor 150 close to the nozzle 130 is located between the nozzle sleeve 140 and the steam pipe 110, rather than between the steam channel 120 and the steam pipe 110, this part of the wire harness 151 will not affect the sealed connection between the nozzle 130 and the steam channel 120, thereby avoiding interference between the wire harness 151 and the nozzle 130.

[0050] See also Figure 2 In some embodiments, the steam wand 100 further includes a sealing component 160, which is disposed in the region between the steam pipe 110 and the steam channel 120 and is located between the wire hole 111 and the outlet end of the steam channel 120. Thus, the sealing component 160 is used to seal the region between the steam pipe 110 and the steam channel 120, and the region between the wire hole 111 and the outlet end of the steam channel 120, thereby preventing the steam ejected from the outlet end of the steam channel 120 from leaking into the space between the steam channel 120 and the cavity wall of the steam pipe 110, thereby preventing the wire harness 151 in the space from being damaged, causing the steam pipe 110 to be scalded, and preventing condensed water from appearing in the pipe.

[0051] See also Figure 2 In some embodiments, the sealing component 160 includes a support ring 161, a first sealing ring 162 and a second sealing ring 163, wherein the first sealing ring 162 and the second sealing ring 163 are located at both ends of the support ring 161, the first sealing ring 162 is extruded and installed between the support ring 161 and the nozzle 130, and the second sealing ring 163 is extruded and installed between the support ring 161 and the steam pipe 110. Since there is a certain interval between the steam channel 120 and the cavity wall of the steam pipe 110, in order to ensure the stability of the steam channel 120 in the steam pipe 110, the sealing component 160 has a certain support, that is, the sealing component 160 includes a support ring 161, and the support ring 161 is arranged between the steam channel 120 and the steam pipe 110, so as to improve the stability of the steam channel 120 in the steam pipe 110 through the support ring 161.

[0052] On the basis of providing the support ring 161, in order to ensure the sealing effect of the sealing component 160, a first sealing ring 162 and a second sealing ring 163 are provided at both ends of the support ring 161 to prevent steam from leaking into the interval between the steam channel 120 and the cavity wall of the steam pipe 110. At the same time, in order to limit the first sealing ring 162 and the second sealing ring 163, a first step 112 and a second step 113 are provided between the cavity wall of the steam pipe 110, the first step 112 is used to fix the first sealing ring 162, and the second step 113 is used to fix the second sealing ring 163. The support ring 161 is provided between the first step 112 and the second step 113, and the first sealing ring 162 and the second sealing ring 163 also play a role in limiting and fixing the support ring 161.

[0053] See also Figure 2In some embodiments, the temperature sensor 150 includes a metal shell 152 and a temperature probe 153. The temperature probe 153 is disposed in the metal shell 152. The metal shell 152 penetrates one end of the nozzle sleeve 140 and extends outward along the axial direction of the steam channel 120. In the case where the metal shell 152 is not provided, if the temperature probe 153 directly collides with the container, the temperature probe 153 may be damaged. Therefore, the metal shell 152 is provided to cover the temperature probe 153, so that the temperature probe 153 is protected by the metal shell 152, and the temperature probe 153 is installed on the nozzle sleeve 140 through the metal shell 152. The metal shell 152 has a heat-conducting function. The metal shell 152 penetrates one end of the nozzle sleeve 140 and extends outward along the axial direction of the steam channel 120, so as to realize the setting that the temperature sensor 150 is installed on the nozzle sleeve 140 and extends outward. Therefore, when the steam wand 100 is used to spray steam into a beverage, the portion of the metal shell 152 extending outside the nozzle sleeve 140 is immersed in the beverage, and the heat of the beverage is transferred to the temperature sensing probe 153 through the metal shell 152, and the temperature sensing probe 153 detects the temperature of the beverage.

[0054] In order to ensure the heat conduction effect of the metal shell 152, the metal shell 152 has a sufficient length to be immersed in the beverage, so the protruding length of the metal shell 152 is set to 2mm~12mm. For example, the protruding length of the metal shell 152 can be 2mm, 3mm, 4mm...10mm, 11mm, 12mm, etc.

[0055] The wiring harness 151 includes a signal line and a ground line, wherein the signal line is electrically connected to the temperature sensing probe 153 to transmit the detection data of the temperature sensor 150 through the signal line. The ground line is electrically connected to the metal shell 152, and the ground line can be riveted on the metal shell 152 so that the temperature sensor 150 can be grounded through the ground line.

[0056] See also Figure 2 In some embodiments, the nozzle 130 is sleeved on the outlet end of the steam channel 120 but is not connected to the steam channel 120, and the nozzle 130 is threadedly connected to the steam pipe 110. Since the temperature sensor 150 is used to directly measure the temperature of the beverage, on the one hand, it is necessary to allow the temperature sensor 150 to be immersed in the beverage together with the steam rod 100, and on the other hand, it is necessary to reduce the influence of the steam sprayed by the steam rod 100 on the temperature sensor 150. Therefore, the outlet of the nozzle 130 is set to be inclined in the direction away from the temperature sensor 150, so that when the nozzle 130 sprays steam, the steam will spray in the direction away from the temperature sensor 150 and will not act on the temperature sensor 150, thus avoiding the influence of the steam sprayed by the nozzle 130 on the temperature sensor 150, so that the temperature sensor 150 can measure the temperature of the beverage more accurately.

[0057] For easy operation of the steam wand 100, please refer to Figure 1 In some embodiments, the steam wand 100 further includes a sheath 170, which is sleeved on the outside of the steam pipe 110, so that the operator can hold the sheath 170 to operate the steam wand 100, thereby preventing the operator from directly touching the steam pipe 110 and getting burned. At the same time, a hook position 171 is provided on the sheath 170, so that the operator can operate the steam wand 100 through the hook position 171.

[0058] See also Figure 1 In some embodiments, the sheath 170 covers the connection between the nozzle sleeve 140 and the steam pipe 110 to maintain the stability of the connection structure between the nozzle sleeve 140 and the steam pipe 110. The sheath 170 is usually fixedly arranged on the steam pipe 110, especially arranged at the bend of the steam pipe 110, which can increase the connection stability of the sheath 170 on the steam pipe 110 and facilitate the operation of the steam wand 100. When the nozzle sleeve 140 is installed on the steam pipe 110, the nozzle sleeve 140 is connected to the sheath 170, which can increase the installation stability of the nozzle sleeve 140. The sheath 170 and the nozzle sleeve 140 can be connected by a snap-fit ​​connection to facilitate the disassembly and assembly of the nozzle sleeve 140. At the same time, the diameter of the sheath 170 is set to be the same as the diameter of the nozzle sleeve 140, so that the sheath 170 and the nozzle sleeve 140 are consistent in appearance, thereby improving the overall texture of the steam wand 100.

[0059] See also Figure 1 In some embodiments, the steam wand 100 is provided with a universal joint 210, and the steam wand 100 is rotatably mounted on the device equipped with the steam wand 100 through the universal joint 210, and the steam wand 100 can be flexibly and freely rotated, thereby facilitating the operation of the steam wand 100 on the device and improving the user experience. The universal joint 210 is a mature prior art, and the specific structure can adopt the relevant disclosure of the prior art, and this application does not limit it.

[0060] In a second embodiment of the present application, a beverage processing device 10 is provided.

[0061] The steam wand 100 is applied to a beverage processing device 10, and the beverage processing device 10 can spray steam into the beverage in the container through the steam wand 100 to change the characteristics of the beverage. On the one hand, the device body 200 provides a mounting base for the steam wand 100, so that the steam wand 100 can be mounted on the device body 200. On the other hand, the device body 200 is provided with a steam generating component and a control device. The steam generating component is used to generate steam, and the steam channel 120 is connected to the steam generating component, so that steam is injected into the steam channel 120 through the steam generating component, and then the steam is discharged through the outlet end of the steam wand 100. The control device is used to receive and process the detection signal of the temperature sensor 150 to determine the temperature of the beverage.

[0062] See also Figure 4 In some embodiments, the device body 200 is provided with a universal joint 210, and the universal joint 210 is connected to one end of the steam pipe 110. The universal joint 210 is provided on the device body 200, and the steam pipe 110 is connected to the universal joint 210, so that the steam wand 100 can be flexibly and freely rotated, thereby facilitating the operation of the steam wand 100 on the device body 200 and improving the user experience. The universal joint 210 is a mature prior art, and the specific structure can adopt the relevant disclosure of the prior art, and this application does not limit it.

[0063] See also Figure 3 In some embodiments, the universal joint 210 is connected to the steam pipe 110 of the steam wand 100, and the universal joint 210 is provided with a through channel 212a, and the steam channel 120 extends outward through the through channel 212a. Since the universal joint 210 is connected to the device body 200, the steam channel 120 can extend into the device body 200 through the through channel 212a and connect to the steam generating assembly. The wire harness 151 of the temperature sensor 150 extends into the area between the universal joint 210 and the steam channel 120. Similarly, since the universal joint 210 is connected to the device body 200, the wire harness 151 can extend into the device body 200 and be electrically connected to the control device.

[0064] See also Figure 3In some embodiments, the universal device 210 includes an upper bracket 211, a ball core 212, a ball seat 213, and a damping member 214. The upper bracket 211 and the ball seat 213 are both provided with an arc surface concave cavity, and after the upper bracket 211 and the ball seat 213 are connected, the two enclose a ball cavity 215. The ball core 212 is rotatably disposed in the ball cavity 215, and the ball core 212 is provided with a through channel 212a for penetrating the steam channel 120. At least one of the upper bracket 211, the ball core 212, and the ball seat 213 is connected to the steam pipe 110. For example, the steam pipe 110 is connected to the upper bracket 211 and / or the ball seat 213, and the ball core 212 is connected to the device body 200.

The rotation of the steam rod 100 on the device body 200 can also be realized by the rotation of the ball core 212 in the ball cavity 215.

[0065] See also Figure 3 In some embodiments, a damping member 214 is provided between the ball core 212 and the cavity wall of the ball cavity 215, and the damping member 214 is in frictional contact with the ball core 212, so as to provide a certain rotation resistance to the steam rod 100 through the damping member 214. During the rotation of the steam rod 100, once the rotation of the steam rod 100 is stopped, the steam rod 100 can be fixed at the current position, thereby facilitating the use of the steam rod 100. The damping member 214 can be a sealing ring or other parts with large friction. The damping member 214 can be an independently arranged part, or it can be integrally formed on the upper bracket 211 and / or the ball seat 213. In some embodiments, the damping member 214 can also be integrally formed on the surface of the ball core 212.

[0066] See also Figure 3 In some embodiments, the ball core 212 includes a ball body 212b and a connecting portion 212c, wherein the connecting portion 212c is used to connect the steam pipe 110. The steam pipe 110 and the ball core 212 are connected together through the connecting portion 212c, so that the steam channel 120 is arranged through the through channel 212a of the ball core 212, so as to facilitate the arrangement of the steam pipe 110 and the steam channel 120 on the universal device 210. The damping member 214 is extruded and installed between the ball body 212b and the ball seat 213, so that the rotation of the steam rod 100 is realized by the rotation of the ball body 212b in the ball seat 213, and when the rotation of the steam rod 100 is stopped by the damping member 214, the steam rod 100 is fixed at the current position, so as to improve the use effect of the steam rod 100.

[0067] In some embodiments, the beverage processing device 10 further includes a second steam wand 300, which is an ordinary steam wand without a temperature measurement function. The second steam wand 300 can be any steam wand structure disclosed in the prior art; the second steam wand 300 can also be regarded as a structure obtained by removing the nozzle sleeve 140 and the temperature sensor 150 from the steam wand 100 of any embodiment of the first aspect described above. The steam wand 100 (i.e., the temperature-detectable steam wand) and the second steam wand 300 (i.e., the non-temperature-detectable steam wand) can be selectively installed on the device body 200, that is, the port on the device body 200 for installing the steam wand is adapted to the steam wand 100 (i.e., the temperature-detectable steam wand) and the second steam wand 300 (i.e., the non-temperature-detectable steam wand). Of course, in some embodiments, the steam wand 100 (i.e., the temperature-detectable steam wand) and the second steam wand 300 (i.e., the non-temperature-detectable steam wand) can also be provided on the device body 200 at the same time.

[0068] See also Figure 5 In some embodiments, the second steam wand 300 includes a steam pipe 110, a steam channel 120 and a nozzle 130. The steam channel 120 is located in the tube cavity of the steam pipe 110 for steam circulation; the nozzle 130 is connected to the outlet end of the steam channel 120 or one end of the steam pipe 110, and is in communication with the steam channel 120. In order to facilitate the replacement between the temperature-detectable steam wand 100 and the non-temperature-detectable steam wand 100, when the temperature-detectable steam wand 100 needs to be converted into the non-temperature-detectable steam wand 100, it is only necessary to remove the nozzle sleeve 140 and the nozzle 130 of the temperature-detectable steam wand 100, and then install the nozzle 130 of the non-temperature-detectable steam wand 100, so as to convert it into the non-temperature-detectable steam wand 100.

[0069] In some embodiments, the beverage processing device 10 is a coffee machine or a milk tea machine. The coffee machine or the milk tea machine is provided with the steam wand 100 in the embodiment of the first aspect of the present application, so as to facilitate the operation of the steam wand 100. When the coffee machine or the milk tea machine is used to make milk froth, the steam wand 100 is rotated so that the outlet end of the steam wand 100 is immersed in the milk, and steam is injected into the milk through the nozzle 130 of the steam wand 100, and the temperature sensor 150 of the steam wand 100 directly detects the temperature of the milk, and the nozzle 130 and the temperature sensor 150 are arranged at intervals, and the steam sprayed by the nozzle 130 has little effect on the temperature sensor 150. Therefore, the operator controls the steam spraying amount of the steam wand 100 according to the temperature detected by the temperature sensor 150, so as to control the temperature of the milk at 50 to 60 degrees Celsius, so as to improve the quality of the milk froth.
