Description

Technical Field

[0001] This utility model belongs to the technical field of electric egg beaters, and more specifically, it relates to an electric egg beater. Background Technology

[0002] An egg beater is used to thoroughly combine egg whites and yolks into an egg mixture, or to beat the egg whites and yolks separately until foamy. An electric egg beater can easily and quickly thoroughly combine egg whites and yolks into an egg mixture for making steamed eggs. An electric egg beater uses a built-in motor to drive the mixing head to rotate, thus achieving mixing. Because the mixing head needs to be connected to the motor inside the casing for power transmission, the casing usually has an opening for the mixing rod to pass through.

[0003] However, in related technologies, electric egg beaters have poor waterproof sealing performance. During the mixing process, splashed liquid can easily enter the shell from the opening, causing damage to the motor or control circuit board and affecting subsequent use. Utility Model Content

The electric egg beater includes a casing, a drive unit, a transmission unit, and a mixing unit. The top of the casing has an installation opening for the mixing unit to pass through. The mixing rod of the mixing unit passes through the installation opening and connects to the transmission unit. The transmission unit connects between the drive unit and the mixing unit, and the drive unit drives the mixing unit to rotate through the transmission unit. The electric egg beater also includes a waterproof part for covering the installation opening. The waterproof part is located on the side of the transmission unit near the mixing unit, and the transmission unit is connected to the mixing unit through the waterproof part.

[0005] Compared with existing technologies, the technical advantages achieved by this solution are: the waterproof section can block the installation opening, preventing splashed liquid from easily entering the housing during stirring, which could damage the motor or control circuit board and affect subsequent use. Furthermore, the waterproof section also functions as a drive unit; when the stirring unit rotates, the waterproof section and the stirring unit rotate synchronously.

[0006] Furthermore, the waterproof part includes an integrally formed waterproof component and a transmission component. One end of the waterproof component has a stirring mounting position for installing the stirring unit, and the other end of the waterproof component is connected to the transmission component. The transmission component is located inside the installation opening, and the waterproof component is located outside the installation opening and covers the installation opening.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: By integrating the waterproof component and the transmission component into a single unit, the waterproof component, located on the outside of the mounting opening, can effectively block the opening from the outside, eliminating the need for internal waterproof sealing rings or similar structures within the housing. Furthermore, the waterproof component serves to mount the stirring unit on the outside of the housing. The transmission component, located within the mounting opening and extending into the housing from the opening, connects to the internal transmission unit, enabling the transmission of driving force. When the driving unit drives the stirring unit to rotate via the transmission unit, the waterproof component and the stirring unit rotate synchronously.

[0008] Furthermore, the waterproof component is a conical seal, with the base area of ​​the conical seal being larger than the area of ​​the installation opening.

[0009] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: compared with other shapes, the conical waterproof component has better waterproof sealing performance and is more aesthetically pleasing.

[0010] Furthermore, the transmission part has a drive mounting position for mounting the output shaft on the side near the drive part, the outer wall of the transmission part has a transmission key, and the transmission component has a snap-fit ​​groove that mates with the transmission key.

[0011] Compared with existing technologies, the technical effect achieved by this technical solution is that the transmission part can drive the transmission component to rotate through the interlocking slots and transmission keys, thereby transmitting the rotational driving force to the waterproof part.

[0012] Furthermore, the transmission key includes a transmission flat key and raised keys on both sides along the width direction of the transmission flat key.

[0013] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: Compared with traditional flat keys, by setting the transmission key as a transmission flat key and setting raised keys on both sides along the width direction of the transmission flat key, the connection stability between the locking groove and the transmission key can be improved.

[0014] Furthermore, the housing includes a front shell, a rear shell, a top cover, and a base; the mounting opening is provided on the top cover, and the top cover has an inner mounting cylinder at the mounting opening; wherein, the transmission key and the snap-fit ​​groove are located inside the inner mounting cylinder.

[0015] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the transmission key and the locking groove are set inside the mounting inner cylinder, which can further improve the connection stability between the locking groove and the transmission key.

[0016] Furthermore, the power supply is a rechargeable battery, and a charging port is provided on the base.

[0017] Compared with existing technologies, the technical effect achieved by adopting this technical solution is that when the power supply unit runs out of power, the user can plug the charging cable into the charging port to charge the power supply unit.

[0018] Furthermore, a charging indicator is provided on the front cover.

[0019] Compared with existing technologies, the technical effect achieved by adopting this technical solution is that users can intuitively see whether it is charging and whether the battery is fully charged through the charging indicator.

[0020] Furthermore, the power switch is located on the front cover, and the power switch has a finger groove.

[0021] Furthermore, a gear indicator is provided on the front cover.

[0022] The technical effects and advantages of this utility model are as follows: 1.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0027] See Figure 1 This is a structural schematic diagram of an electric egg beater provided by this utility model. Combined with... Figures 1 to 14An electric egg beater includes, for example, a housing 10, a power supply unit (not shown), a control circuit board (not shown), a drive unit 30, a transmission unit 40, a waterproof unit 50, and a mixing unit 60. The housing 10 has a mounting opening 131 at its top. The transmission unit 40 connects the drive unit 30 and the mixing unit 60, and the drive unit 30 drives the mixing unit 60 to rotate via the transmission unit 40. The power supply unit, control circuit board, drive unit 30, and transmission unit 40 are located inside the housing, while the mixing unit 60 is located outside the housing. The waterproof unit 50 covers the mounting opening 131 at the top of the housing 10 to prevent splashed liquid from entering the housing through the mounting opening 131. In one specific embodiment, the waterproof unit 50 is disposed between the transmission unit 40 and the mixing unit 60, and the transmission unit 40 is connected to the mixing unit 60 via the waterproof unit 50. For example, the upper part of the waterproof part 50 is located on the outside of the housing 10 and is used to cover the mounting opening 131; the lower part of the waterproof part 50 passes through the mounting opening 131 and is connected to the transmission part 40 inside the housing 10, so as to transmit the driving force provided by the drive part 30 inside the housing 10 to the stirring part 60 outside the housing.

[0028] Compared with existing technologies, the technical effects achieved by this solution are as follows: the waterproof part 50 can block the installation opening 131, preventing splashed liquid during stirring from easily entering the housing 10 through the opening, which could damage the motor or control circuit board and affect subsequent use. Furthermore, the waterproof part 50 also functions as a drive unit; when the stirring part 60 rotates, the waterproof part 50 and the stirring part 60 rotate synchronously.

[0029] Furthermore, the waterproof part 50 includes an integrally formed waterproof component 51 and a transmission component 52. One end of the waterproof component 51 has a stirring mounting position 511 for mounting the stirring part 60, and the other end of the waterproof component 51 is connected to the transmission component 52. The transmission component 52 is disposed within the mounting opening 131, and the waterproof component 51 is located outside the mounting opening 131 and covers it. For example, the waterproof component 51 is a conical seal with a base area larger than the area of ​​the mounting opening 131. Compared to other shapes, the conical waterproof component offers better waterproof sealing performance and is also more aesthetically pleasing. For example, the stirring mounting position 511 is a mounting hole that does not penetrate the waterproof component 51 and is not connected to the interior of the housing 10. Because the stirring mounting position 511 does not penetrate the waterproof component 51, even if splashed liquid enters the stirring mounting position 511, it will not enter the interior of the housing 10 from the stirring mounting position 511, thus preventing damage to the electronic components inside the housing 10.

[0030] Understandably, by making the waterproof part 50 an integrally formed waterproof component 51 and transmission component 52, the waterproof component 51, located outside the mounting opening 131, can block the mounting opening 131 from the outside, eliminating the need for a waterproof sealing ring or similar structure inside the housing 10. On the other hand, the waterproof component 51 is used to mount the stirring part 60 on the outside of the housing 10. The transmission component 52, located inside the mounting opening 131 and extending into the housing 10 from the mounting opening 131, connects to the transmission part 40 inside the housing 10, enabling the transmission of driving force. When the drive unit 30 drives the stirring part 60 to rotate via the transmission part 40, the waterproof part 50 and the stirring part 60 rotate synchronously.

[0031] Furthermore, the transmission part 40 has a drive mounting position 41 for mounting the output shaft 31 on the side near the drive part 30. The outer wall of the transmission part 40 has a transmission key 42, and the transmission component 52 has a snap-fit ​​groove 521 that mates with the transmission key 42. When the output shaft 31 of the drive part 30 rotates, it can drive the transmission part 40 to rotate through the drive mounting position 41. The transmission part 40 can drive the transmission component 52 to rotate through the mating snap-fit ​​groove 521 and the transmission key 42, thereby transmitting the rotational driving force to the waterproof part 50.

[0032] Preferably, the transmission key 42 includes a transmission flat key 421 and raised keys 422 disposed on both sides of the transmission flat key 421 along its width direction. It can be understood that, compared with a conventional flat key, by setting the transmission key 42 in the form of a transmission flat key 421 and raised keys 422 disposed on both sides of the transmission flat key 421 along its width direction, the connection stability between the locking groove 521 and the transmission key 42 can be improved.

[0033] In one specific embodiment, two transmission keys 42 are symmetrically arranged on the outer wall of the transmission part 40. The transmission part 40 has a cylindrical structure, and the cross-sectional area of ​​the transmission part 40 on the side closer to the waterproof part 50 is smaller than the cross-sectional area of ​​the transmission part 40 on the side farther from the waterproof part 50, so as to facilitate the insertion of the transmission key 42 into the locking groove 521. For example, when the transmission key 42 is installed into the locking groove 521, the transmission member 52 undergoes elastic deformation, and the opening of the locking groove 521 becomes larger, allowing the transmission key 42 to be inserted into the locking groove 521.

[0034] Furthermore, the housing 10 includes a front housing 11, a rear housing 12, a top cover 13, and a base 14; a mounting opening 131 is formed on the top cover 13, and an inner mounting cylinder 132 is provided inside the top cover 13 at the mounting opening 131; wherein, the transmission key 42 and the snap-fit ​​groove 521 are disposed within the inner mounting cylinder 132, and the inner mounting cylinder 132 can further improve the connection stability between the snap-fit ​​groove 521 and the transmission key 42. Preferably, reinforcing ribs 133 are also provided between the inner wall of the top cover 13 and the inner mounting cylinder 132. Four reinforcing ribs 133 are connected between the inner wall of the top cover 13 and the inner mounting cylinder 132, which can improve the strength and prevent the inner mounting cylinder 132 from deforming.

[0035] Furthermore, the power supply is a rechargeable battery, and a charging port 20 is provided on the base 14. When the power supply runs out of power, the user can plug the charging cable into the charging port 20 to charge the power supply. For example, the electric mixer can be charged by plugging a charging adapter into a power outlet, or it can be charged by a power bank.

[0036] Furthermore, a charging indicator 113 is provided on the front cover 11. For example, a charging indicator light is provided on the control circuit board. When the user plugs the charging cable into the charging port 20 to charge the power supply unit, the charging indicator light lights up, and the user can intuitively see whether it is charging and whether the battery is fully charged through the charging indicator 113. In a specific embodiment, during charging, the user can intuitively see a solid red light through the charging indicator 113, and when the battery is fully charged, the user can intuitively see a solid green light through the charging indicator 113.

[0037] Furthermore, the switch button 111 is located on the front cover 11, and the switch button 111 has a finger groove 112 to facilitate user pressing operation and improve the user experience.

[0038] Furthermore, the front housing 11 is provided with a gear position indicator 114. For example, the gear position indicator 114 includes three gear positions: first gear, second gear, and third gear. The control circuit board is provided with gear position indicator lights. When the user presses the switch button 111 once, the first gear position indicator light illuminates; when the user presses the switch button 111 twice, the second gear position indicator light illuminates; and when the user presses the switch button 111 three times, the third gear position indicator light illuminates.
