Description

Technical Field

[0001] Some embodiments of this utility model relate to a milk frothing device, and more particularly to a milk frothing machine connector, a battery module, and a milk frothing machine. Background Technology

[0002] A milk frother uses a device that generates eddies in liquid milk by adding it to various liquid storage containers. The device continuously stirs the liquid milk in the storage containers and filters, cuts and heats the liquid milk during stirring to produce milk foam.

[0003] Currently, milk frothers require users to hold the machine and flip it to pour the froth from the container after frothing liquid milk. However, due to their weight, and to ensure stability during frothing, the battery module is typically located at the bottom of the machine to concentrate its weight and reduce shaking / vibration. But the considerable weight of current milk frothers still affects the ease of operation, especially when pouring the milk after frothing. Utility Model Content

[0004] The purpose of this invention is to design a connector for a milk frother, a battery module, and a milk frother. This design not only does not affect the normal power supply of the battery module to the main body of the milk frother, but also allows the user to easily pour out the liquid milk after the milk frother has finished frothing the liquid milk. This facilitates the user's handheld operation of the milk frother and improves the user experience.

[0005] To achieve the above objectives, some embodiments of this utility model provide a connecting base for a milk frother, including: A substrate; the substrate has an upper surface and a lower surface opposite to the upper surface along a preset axial direction, and the substrate is used for an electrical connector on the control board of a milk frother to pass through, so that a portion of the electrical connector is exposed on the lower surface of the substrate. A connecting portion is formed around the circumference of the substrate; the connecting portion is used for detachable connection with the battery module of the milk frother, so that the battery module is fixed to the lower surface of the substrate and the battery module is electrically connected to the electrical connector.

[0006] In addition, some embodiments of this utility model also provide a battery module for a milk frother, for detachable connection with the connector described above, the battery module comprising: The outer casing is detachably connected to the connecting portion of the connecting seat; A battery module is disposed inside the housing; the battery module has an electrical connection part, a portion of which is exposed outside the housing, for connecting the housing and the connection part of the connector to electrically connect the electrical connection part to the electrical connector on the control board of the milk frother.

[0007] In addition, some embodiments of this utility model also provide a milk frother, including: The connector as described above; The main control module includes: a control board disposed opposite to the upper surface of the substrate of the connector, and an electrical connector disposed on the control board; wherein a portion of the electrical connector passes through the substrate and is exposed on the lower surface of the substrate. The battery module described above is disposed on the lower surface of the substrate along a preset axial direction; wherein the outer shell of the battery module is detachable from the connecting portion, and the electrical connection portion of the battery module is electrically connected to the electrical connection component of the main control module; The main body of the milk frother is located on the side of the connecting part away from the battery module along the preset axis direction and is electrically connected to the control board.

[0008] Compared with the prior art, the embodiments of this utility model include a base plate and a connecting part arranged circumferentially along the base plate. The base plate can be penetrated by electrical connectors on the control board of the milk frother, so that part of the electrical connectors can be exposed on the lower surface of the base plate. The connecting part can be detachably connected to the battery module of the milk frother. After the connecting part is connected to the battery module, the electrical connectors of the control board can be directly connected to the battery module, so that the control board can stably control the main body of the milk frother to ensure that the milk frother can properly frother liquid milk. After the milk frother has finished frothering the liquid milk, the user can separate the connecting base from the battery module. Therefore, the weight of the milk frother can be greatly reduced, making it easier for the user to operate the milk frother by hand and to pour out the milk foam, thus improving the user experience.

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0011] Example 1 The first embodiment of this utility model relates to a connecting base for a milk frother, such as... Figure 1 and Figure 2 As shown, the connector 1 includes a base plate 11 and a connecting portion 12. Wherein, it is combined with... Figure 7 As shown, the substrate 11 has an upper surface 111 and a lower surface 112 opposite to the upper surface 111 along a preset axial direction, and the substrate 11 is used for the electrical connector 22 on the control board 21 of the milk frother to pass through, so that part of the electrical connector 22 is exposed on the lower surface 112 of the substrate 11.

[0012] Secondly, such as Figure 1 As shown, the connecting portion 12 is formed around the circumference of the substrate 11 and is combined with... Figure 7 As shown, the connecting part 12 is used to detachably connect to the battery module 3 of the milk frother, so that the battery module 3 is fixed to the lower surface 112 of the substrate 11, and the battery module 3 is electrically connected to the electrical connector 22.

[0013] As can be seen from the above, the connecting base includes a base plate 11 and a connecting portion 12 arranged circumferentially along the base plate 11. The base plate 11 can be penetrated by an electrical connector 22 on the control board 21 of the milk frother, so that part of the electrical connector 22 can be exposed on the lower surface 112 of the base plate 11. The connecting portion 12 can be detachably connected to the battery module 3 of the milk frother. After the connecting portion 12 is connected to the battery module 3, the electrical connector 22 of the control board 21 can be directly connected to the battery module 3, so that the battery module 3 can stably supply power to the control board 21 of the milk frother, thereby ensuring that the milk frother can normally frother liquid milk. After the milk frother has finished frothering the liquid milk, the user can separate the connecting base 1 from the battery module 3, thus greatly reducing the weight of the milk frother at this time, making it easier for the user to operate the milk frother by hand, making it convenient for the user to pour out the milk foam, and improving the user experience.

[0014] Specifically, in some embodiments, such as Figure 7 As shown, the electrical connector 22 is a terminal connector, which includes at least one connection terminal 221 and is coupled with Figure 1 and Figure 2 As shown, the substrate 11 has at least one positioning hole 113 along a predetermined axis. Wherein, as... Figure 7 As shown, each positioning hole 113 is used for insertion of at least one connecting terminal 221, and each connecting terminal 221 is partially exposed on the lower surface 112 of the substrate 11. For example, in some embodiments, such as Figure 1 , Figure 2 and Figure 7 As shown, the number of connecting terminals 221 and positioning holes 113 are the same and uniquely correspond, and each connecting terminal 221 is inserted into its unique corresponding positioning hole 113, so that each connecting terminal 221 is partially exposed on the lower surface 112 of the substrate 11. Therefore, when the battery module 3 and the connecting portion 12 of the connector 1 are connected, as shown... Figure 7 As shown, each connection terminal 221 of the electrical connector 22 can abut against the electrical connection portion 321 of the battery module 3, thereby enabling the electrical connector 22 to complete the electrical connection with the electrical connection portion 321. Furthermore, in order to enable the connecting portion 12 of the connector 1 to be detachably connected to the battery module 3, in some embodiments, such as Figure 1 and Figure 7 As shown, the connecting portion 12 includes: an inner wall 121, an outer wall 122 opposite to the inner wall 121, and a connecting wall 123 connected to the inner wall 121 and the outer wall 122 respectively. The inner wall 121 is connected to the substrate 11 along the circumference of the substrate 11, and extends in a direction away from the upper surface 111 of the substrate 11, so that the inner wall 121 can form a positioning groove 124 for positioning the battery module 3 on the lower surface 112 of the substrate 11. Next, as... Figure 7As shown, the connecting wall 123 is disposed between the inner wall 121 and the outer wall 122, and is connected to both the inner wall 121 and the outer wall 122 respectively, so that the connecting wall 123 can abut against the battery module 3, and so that the connecting wall 123 can position the battery module 3 for installation. Finally, as Figure 7 As shown, the outer wall 122 extends toward the lower surface 112 away from the substrate 11, so that the outer wall 122 forms a mounting area 13 on the upper surface 111 of the substrate 11 for mounting the control board 21. The control board 21 of the milk frother can be mounted through this mounting area 13.

[0015] Furthermore, it is worth noting that in some embodiments, since the inner wall 121 can form a positioning groove 124 on the lower surface 112 of the substrate 11, when the battery module 3 is assembled with the connector 1, such as Figure 7 As shown, a portion of the upper shell 311 of the battery module 3 can be inserted into the positioning groove 124 of the connecting part 12, thereby laying the foundation for the detachable connection between the upper shell 311 of the battery module 3 and the connecting part 12.

[0016] It should be noted that in some embodiments, the connecting part 12 can be connected to the upper shell 311 of the battery module 3 by a snap-fit ​​method. For example, in some embodiments, such as Figure 2 and Figure 7 As shown, the positioning groove 124 is used for the battery module 3 to rotate relative to the connecting seat 1 with a preset axis as the pivot axis, and in conjunction with... Figure 2 and Figure 6 As shown, at least one first latching portion 125 and at least one second latching portion 126 are provided on the side of the inner wall 121 away from the outer wall 122. Furthermore, when the battery module 3 is rotated forward relative to the connecting seat 1 to the first preset position, as... Figure 6 As shown, each of the first latching portions 125 can latch onto the battery module 3 around a preset axis, while the second latching portion 126 can latch onto the battery module 3 along the preset axis, so that the battery module 3 can be positioned at the current position. Conversely, when the battery module 3 rotates in the opposite direction relative to the connecting seat 1 to the second preset position, each of the first latching portions 125 can separate from the battery module around the preset axis, and the second latching portion 126 can separate from the battery module 3 along the preset axis, so that the battery module 3 can be removed from the connecting seat 1.

[0017] In addition, to facilitate the installation and removal of the connector 1 and the battery module 3, as a preferred embodiment, in some cases, such as Figure 2 and Figure 6As shown, a portion of the inner wall 121 of the connecting part 12 protrudes away from the outer wall 122 to form a limiting part 127 around a preset axis direction, and a limiting groove 128 is formed between each two adjacent limiting parts 127. Each limiting groove 128 is used to limit the rotation angle of the battery module 3 relative to the connecting seat 1 when it rotates.

[0018] Example 2 Embodiment 2 of this utility model relates to a battery module for a milk frother, such as... Figure 3 and Figure 7 As shown, the battery module 3 is used for detachable connection with the connector 1 as described in Embodiment 1. The battery module 3 includes a housing 31 and a battery module 32. The housing 31 is detachably connected to the connection portion 12 of the connector 1.

[0019] Additionally, in some embodiments, such as Figure 7 As shown, the battery module 32 is disposed within the housing 31. The battery module 32 has an electrical connection portion 321 and is combined with... Figure 3 As shown, part of the electrical connection 321 is exposed outside the housing 31. After the housing 31 is connected to the connection part 12 of the connector 1, the electrical connection 321 is electrically connected to the electrical connector 22 on the control board 21 of the milk frother.

[0020] It is clear from the above that, since the battery module 3 includes a housing 31 and a battery module 32 disposed within the housing 31, and the housing 31 is detachably connected to the connecting portion 12 of the connector 1, and the battery module 32 has an electrical connection portion 321, with a portion of the electrical connection portion 321 exposed outside the housing 31, and the housing 31 of the battery module 3 is detachably connected to the connecting portion 12 of the connector 1, the battery module 3 can be installed on the connector 1. Furthermore, when the housing 31 of the battery module 3 is connected to the connecting portion 12 of the connector 1, the battery module 3 can be installed on the connector 1. After connection, the electrical connection part 321 of the battery module 3 can be electrically connected to the electrical connection part 22 of the control board 21, so that the battery module 3 can stably supply power to the control board 21 of the milk frother, thereby ensuring that the milk frother can normally achieve the frothing of liquid milk. After the milk frother has finished frothing the liquid milk, the user can separate the battery module 3 from the connector 1, which can greatly reduce the weight of the milk frother at this time, making it easier for the user to operate the milk frother by hand and convenient for the user to pour out the milk foam, thus improving the user experience.

[0021] Specifically, in some embodiments, the electrical connection portion 321 of the battery module 32 is a terminal connector, and as shown in the figure... Figure 3 and Figure 7As shown, the electrical connection portion 321 includes at least one contact terminal 3211. Corresponding to the terminal connector, the outer casing 31, along a predetermined axial direction, includes: a lower casing 312 and an upper casing 311 that closes the lower casing 312. The lower casing 312 and the upper casing 311 together form an accommodating space 33, and the battery module 32 is disposed within the accommodating space 33. Furthermore, combined with... Figure 7 As shown, the upper housing 311 is provided with at least one connection hole 314, and each connection hole 314 is respectively used for at least one contact terminal 3211 to pass through, so that each contact terminal 3211 is partially exposed on the side of the upper housing 311 away from the lower housing 312. For example, in some embodiments, such as Figure 7 As shown, the number of contact terminals 3211 and the number of connection holes 314 are the same and uniquely correspond, and each contact terminal 3211 is inserted into its unique corresponding connection hole 314, so that each contact terminal 3211 is partially exposed outside the upper shell 311. Thus, when the connection part 12 between the battery module 3 and the connector 1 is completed, as shown... Figure 7 As shown, each contact terminal 3211 on the battery module 32 can abut against each connection terminal 221 of the electrical connector 22 on the control board 21, so that the electrical connection portion 321 of the battery module 32 can be electrically connected to the electrical connector 22 of the control board 21, thereby ensuring that the battery module 32 can provide stable power to the control board 21. It should also be noted that, in order to further improve the stability of the electrical connection between the electrical connection portion 321 and the electrical connector 22, in some embodiments, each contact terminal 3211 of the electrical connection portion 321 and / or each connection terminal 221 of the electrical connector 22 are elastic terminals, so that after the electrical connection portion 321 abuts against the electrical connector 22, the stability of the electrical connection between the electrical connection portion 321 and the electrical connector 22 can be improved.

[0022] In addition, in order to enable the housing 31 of the battery module 3 to be detachably connected to the connector 1, in some embodiments, such as Figure 3 and Figure 7 As shown, the upper shell 311 of the battery module 3 includes: a top plate 3111, an upper side wall 3112, a support wall 3113, and a lower side wall 3114. Among them, as... Figure 7 As shown, the top plate 3111 has a top side 31111 and a bottom side 31112 opposite to the top side 31111 along a predetermined axis direction, and the top plate 3111 is provided with at least one connecting hole 314 along the predetermined axis direction. Furthermore, the upper sidewall 3112 is connected to the top plate 3111 circumferentially along the top plate 3111, and extends away from the top side 31111, and is also used for detachable connection with the connecting portion 12 of the connecting seat 1. Additionally, as... Figure 3 and Figure 7As shown, the support wall 3113 extends horizontally from the end of the upper side wall 3112 away from the top plate 3111 in a direction away from the preset axis, and the support wall 3113 is used to support the connecting part 12 of the connecting seat 1 along the preset axis. Finally, the lower side wall 3114 is connected to the side of the support wall 3113 away from the upper side wall 3112, and extends vertically in a direction away from the top plate 3111, and the lower side wall 3114 is also connected to the lower shell 312, so that the upper shell 311 can completely close the lower shell 312.

[0023] Furthermore, it is evident from the above embodiment 1 that, since the connecting portion 12 of the connector 1 forms a positioning groove 124 on the lower surface 112 of the substrate 11 into which the upper shell 311 can be partially inserted, in some embodiments, the outer diameter of the upper sidewall 3112 is substantially the same as the inner diameter of the positioning groove 124. Therefore, when it is necessary to assemble the upper shell 311 of the battery module 3 with the connector 1, such as Figure 7 As shown, the top plate 3111 and the upper sidewall 3112 of the upper shell 311 can be inserted together into the positioning groove 124, and the upper sidewall 3112 of the upper shell 311 can also be snapped into connection with the connecting part 12. For example, when the upper sidewall 3112 and the top plate 3111 of the upper shell 311 are inserted into the positioning groove 124, the battery module 3 can rotate relative to the connecting seat 1 about a preset axis as the pivot axis. Furthermore, it is worth noting that in some embodiments, such as... Figure 7 As shown, the upper sidewall 3112 has an inner side 31121 and an outer side 31122 opposite to the inner side 31121, and is combined with Figure 3 and Figure 6 As shown, a portion of the outer side 31122 of the upper sidewall 3112 protrudes away from the inner side 31121 to form at least one positioning portion 31123, and each positioning portion 31123 is used to limit the rotation angle of the battery module 3 relative to the connecting seat 1. For example, in some embodiments, such as Figure 2 and Figure 3 As shown, the number of positioning parts 31123 is the same as and uniquely corresponds to the number of limiting grooves 128 on the connecting seat 1. Therefore, when the upper sidewall 3112 of the upper shell 311 is inserted into the positioning groove 124 of the connecting seat 1, as... Figure 7 As shown, each positioning part 31123 can directly enter its unique corresponding limiting groove 128. Through the cooperation of each positioning part 31123 with its unique corresponding limiting groove 128, the rotation angle of the battery module 3 can be limited. Therefore, when the battery module 3 rotates forward to the first preset position, as... Figure 6As shown, each positioning part 31123 engages with each first engaging part 125 around a preset axis, and simultaneously engages with each second engaging part 126 along the preset axis, so that the battery film assembly 3 can be positioned in the current position. Conversely, when the battery module 3 rotates in the opposite direction to the second preset position, each positioning part 31123 separates from each first engaging part 125 around the preset axis, and simultaneously separates from each second engaging part 126 along the preset axis, so that the battery module 3 can be removed from the connecting seat 1.

[0024] Furthermore, it is worth noting that, in order to enable each positioning part 31123 to engage with each first engaging part 125 around a preset axis direction, and to enable each positioning part 31123 to engage with each second engaging part 126 along a preset axis direction, in some embodiments, such as Figure 3 As shown, the positioning part 31123 can be positioned as close as possible to the top plate 3111. Simultaneously, the outer side 31122 of each positioning part 31123 has a portion recessed to form a slot 31124. Therefore, when the upper side wall 3112 and top plate 3111 of the upper shell 311 of the battery module 3 are inserted into the positioning slot 124 of the connector 1, each positioning part 31123 just passes over each of the second engaging parts 126 of the connector 1. Thus, when the battery module 3 rotates forward to the first preset position, as... Figure 6 As shown, each positioning part 31123 can abut against each second engaging part 126 along a preset axis direction, while each slot 31124 of each positioning part 31123 can be engaged by each first engaging part 125 of the connecting seat 1, so that the battery module 3 cannot be moved or rotated along or around the preset axis direction, thereby achieving the engagement of the battery module 3 with the connecting seat 1. Conversely, when the battery module 3 rotates in the opposite direction to the second preset position, each second engaging part 126 of the connecting seat 1 can disengage from each slot 31124 of each positioning part 31123, while each first engaging part 125 of the connecting seat 1 can be misaligned with each positioning part 31123, so that the battery module 3 can be separated from the connecting seat 1, thereby completing the disassembly of the battery module 3.

[0025] Example 3 Embodiment 3 of this utility model relates to a milk frother, such as... Figure 4 and Figure 5 As shown, the milk frother includes: a connector 1 as described in Embodiment 1, a battery module 3 as described in Embodiment 2, a main control module 2, and a milk frother body 4.

[0026] Among them, such as Figure 7As shown, the main control module 2 includes: a control board 21 disposed opposite to the upper surface 111 of the substrate 11 of the connector 1, and an electrical connector 22 disposed on the control board 21. The electrical connector 22 partially passes through the substrate 11 of the connector 1 and is exposed on the lower surface 112 of the substrate 11.

[0027] Secondly, such as Figure 7 As shown, the battery module 3 is disposed on the lower surface 112 of the substrate 11 along a preset axis direction, and the housing 31 of the battery module 3 and the connection part 12 of the connector 1 are detachable, so that the electrical connection part 321 of the battery module 3 is electrically connected to the electrical connection part 22 of the main control module 2.

[0028] Finally, as Figure 5 As shown, the milk frother body 4 is positioned along a preset axis on the side of the connecting part 12 away from the battery module 3, and is electrically connected to the control board 21.

[0029] It is clear from the above that, since the battery module 3 includes a housing 31 and a battery module 32 disposed within the housing 31, and the housing 31 is detachably connected to the connection portion 12 of the connector 1, and the battery module 32 has an electrical connection portion 321, with a portion of the electrical connection portion 321 exposed outside the housing 31, and the housing 31 of the battery module 3 is detachably connected to the connection portion 12 of the connector 1, the battery module 3 can be installed on the connector 1. Furthermore, when the housing 31 of the battery module 3 is connected to the connection portion 12 of the connector 1... After the connection is completed, the electrical connection part 321 of the battery module 3 can be electrically connected to the electrical connection part 22 of the control board 21, so that the battery module 3 can stably supply power to the control board 21 of the milk frother, thereby ensuring that the milk frother can normally frother the liquid milk. After the milk frother has finished frothering the liquid milk, the user can separate the battery module 3 from the connector 1, which can greatly reduce the weight of the milk frother at this time, making it easier for the user to operate the milk frother by hand, making it convenient for the user to pour out the milk foam, and improving the user experience.

[0030] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
