Description

Technical Field

[0001] The utility model relates to the technical field of control switches, in particular to an integrated switch structure and a handheld blender. Background Art

[0002] In a handheld blender, the switch structure is an important active functional structural component of the handheld blender. In order to realize different switch functions, multiple switches are usually provided, such as a start switch and a speed control switch.

[0003] The Chinese utility model patent with authorization announcement number CN205006701U discloses a hand-held blender with an integrated speed regulation and switch device, including a casing, a mixing motor installed in the casing, an output shaft of the mixing motor extending out of the casing and connected to a mixing blade, a circuit board installed in the casing, a micro switch for connecting the power supply and a potentiometer for speed regulation connected to the circuit board, a multi-function button elastically installed on the casing, when the multi-function button is pressed, the multi-function button simultaneously touches the switch on the micro switch and rotates the rotating shaft on the potentiometer, thereby realizing the power connection and speed adjustment of the mixing motor. Although this structure can realize the dual functions of switching and speed regulation with one click, reducing the safety accidents such as splashing that are easy to occur when operating with both hands, however, since the micro switch and potentiometer are electrically connected to the circuit board separately, the micro switch and potentiometer need to be installed on the circuit board one by one during installation, which has low installation efficiency. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the utility model provides an integrated switch structure and a hand-held blender.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model provides an integrated switch structure, comprising:

[0007] a first housing; and

[0008] At least two switches are provided on the first housing, and the functions of the at least two switches are different. The switches are used to control electrical conduction and disconnection between the switches and the circuit board.

[0009] The integrated switch structure of the present invention includes a first housing and at least two switches, and the functions of the at least two switches are different. For example, one of the switches can be configured to control the opening and closing of the hand-held blender drive, and the other switch can be configured to adjust the speed of the hand-held blender drive. Since the at least two switches are both arranged on the first housing, at least two switches with different functions can be integrated on the same first housing, thereby forming a modular integrated switch structure. The modular integrated switch structure can be independently manufactured and assembled. After assembly, the modular integrated switch structure and the circuit board are assembled together on the main production line, which can reduce construction difficulty. Compared with two independently arranged switches, the integrated switch structure is more convenient to install and can improve installation efficiency. At the same time, the modular manufacturing of the modular integrated switch structure can improve production efficiency, reduce waste, and reduce production costs, thereby reducing the cost of the integrated switch structure and being more conducive to the promotion and application of the integrated switch structure. In addition, the distance between two adjacent switches of the integrated switch structure is fixed, which facilitates the standardized production of the integrated switch structure and can further reduce production costs. In addition, the overall structure of the integrated switch structure can be made more compact, thereby reducing space occupation.

[0010] In one embodiment, the switch comprises:

[0011] a terminal, the terminal being provided on the first housing and being used for electrically connecting to a circuit board;

[0012] a contact member movably provided on the first housing, the contact member having a connected state in which the contact member abuts against the terminal to electrically connect the switch and the circuit board, and a separated state in which the contact member is separated from the terminal to electrically disconnect the switch and the circuit board, and the contact member is configured to move from the separated state to the connected state when pressed, and maintain the separated state when not pressed; and

[0013] An elastic member is disposed between the contact member and the first housing, and is used to provide a driving force for the contact member to maintain the separated state. Because the switch comprises a terminal, contact member, and elastic member, it has fewer components than a micro switch, simplifying the structure and reducing costs, further facilitating the widespread application of integrated switch structures.

[0014] In one embodiment, the integrated switch structure further includes:

[0015] a second shell, the second shell having a receiving cavity, the receiving cavity receiving the first shell;

[0016] At least two button bodies are provided on the second shell 1 in a pressable and movably manner. The button bodies are configured to overcome the driving force of the elastic member when pressed and drive the contact member on the corresponding switch to switch from the separated state to the connected state. In this way, the button body can be maintained in an unpressed state under the action of the elastic member. Therefore, there is no need to set an elastic structure between the button body and the contact member, which reduces the number of parts and simplifies the structure. While improving the installation efficiency, it can also reduce costs and is more conducive to the promotion and application of the integrated switch structure.

[0017] In one embodiment, the switch further includes a push cap, which is movably disposed on the first housing and positioned between the key body and the contact member. The push cap is connected to the contact member and can move with the key body to drive the contact member to switch from the disconnected state to the connected state. The push cap is made of an insulating material. The provision of the push cap can provide insulation to ensure safe operation.

[0018] In one embodiment, the first shell has an inner cavity and a first guide hole, and the first guide hole is connected to the inner cavity;

[0019] Part of the terminal, the contact piece and the elastic piece are all located in the inner cavity, and the remaining part of the terminal is exposed from the first shell and is used to be electrically connected to the circuit board. The pressing cap can be movably passed through the first guide hole, and the pressing cap is provided with a first limiting portion. The outer diameter of the first limiting portion is larger than the aperture of the first guide hole. The first limiting portion can be abutted against the cavity wall of the inner cavity to limit the pressing cap from disengaging from the first guide hole. Among them, since part of the terminal, the contact piece and the elastic piece are all located in the inner cavity, part of the terminal, the contact piece and the elastic piece can be built into the first shell, so that part of the terminal, the contact piece and the elastic piece are protected from the influence of the external environment, such as dust, moisture and chemicals. At the same time, it helps to fix the terminal, the contact piece and the elastic piece to prevent the terminal, the contact piece and the elastic piece from being displaced or damaged when subjected to external force. At the same time, through the cooperation between the pressing cap and the first guide hole, the pressing cap can be guided to move, so that the pressing cap moves more smoothly and avoids jamming. In addition, the first limiting part is abutted against the cavity wall of the inner cavity to limit the pressing cap from detaching from the first guide hole, so that the pressing cap can be reliably installed on the first shell. The structure is simple and practical, the cost is low, and the reliability is high.

[0020] In one embodiment, the push cap has a slot on a side facing away from the button body, and the contact member is provided with a snap-in protrusion that snaps into the slot to connect the push cap and the contact member together. Thus, by snapping the snap-in protrusion into the slot, the push cap and the contact member can be installed together, making the installation operation simple and convenient, and improving installation efficiency. Furthermore, because the snap-in protrusion is located in the slot, the contact member is partially embedded in the push cap, shortening the structural length of the push cap and contact member after installation, thereby making the modular integrated switch structure more compact and taking up less space.

[0021] In one embodiment, the contact member further includes a contact portion disposed around the engaging protrusion, and the contact portion abuts or separates from the terminal. Because the contact portion is disposed around the engaging protrusion, the surface area of ​​the contact portion is increased. The contact portion with a larger surface area abuts the terminal, thereby increasing the contact area between the contact member and the terminal, thereby ensuring reliable electrical conduction between the switch and the circuit board and enhancing structural reliability.

[0022] In one embodiment, the first housing has a first connecting groove, the first connecting groove is located in the inner cavity, and the contact member has a second connecting groove;

[0023] One end of the elastic member is inserted into the first connecting groove, and the other end of the elastic member is inserted into the second connecting groove. Thus, during installation, the elastic member can be connected to the first housing and the contact member by inserting one end of the elastic member into the first connecting groove and the other end into the second connecting groove. This makes installation simple and convenient, improves installation efficiency, and increases connection reliability. Furthermore, because one end of the elastic member is built into the first housing and the other end of the elastic member is built into the contact member, the length of the assembled first housing, elastic member, and contact member can be shortened, making the modular integrated switch structure more compact and taking up less space.

[0024] In one embodiment, the second housing further has a second guide hole, and the second guide hole is connected to the accommodating cavity;

[0025] The button body is provided with a pressing part, a connecting part and a pressing part, the pressing part is exposed from the second shell, the connecting part is connected to the pressing part and is arranged around the pressing part, the connecting part is movably passed through the second guide hole, and the end of the connecting part away from the pressing part is provided with a second limiting part, the second limiting part is located in the accommodating cavity, the outer diameter of the second limiting part is larger than the aperture of the second guide hole, the second limiting part can be abutted against the cavity wall of the accommodating cavity to limit the connecting part from disengaging from the second guide hole, one end of the pressing part is connected to the pressing part, and the other end of the pressing part is abutted against the contact member. Since the accommodating cavity accommodates the first shell, the modular integrated switch structure can be built into the second shell, so that the modular integrated switch structure is protected from the external environment, that is, it plays a role in protecting the modular integrated switch structure. In addition, since the connecting part of the key body cooperates with the second guide hole, the key body can be guided to move, so that the key body moves more smoothly and stably, avoids jamming, and has a better operating feel. In addition, since the second limiting part is located in the accommodating cavity, the outer diameter of the second limiting part is larger than the aperture of the second guide hole, and the second limiting part can be offset against the cavity wall of the accommodating cavity, it is possible to limit the connection part from being separated from the second guide hole, thereby realizing the reliable installation of the key body on the second shell. The structure is simple and practical, the cost is low, and the connection reliability is high.

[0026] In one embodiment, the connecting portion and the pressing portion are spaced apart, and the connecting portion has a reduced diameter state that moves toward the pressing portion so that the second limiting portion can enter and exit the second guide hole. The connecting portion also has an expanded diameter state that expands in a direction away from the pressing portion so as to limit the second limiting portion from being separated from the accommodating cavity. The connecting portion is elastic so that the connecting portion can maintain the expanded diameter state. In this way, during installation, the connecting portion is switched from the expanded diameter state to the reduced diameter state by pinching the connecting portion with the fingers, and then the connecting portion is passed through the second guide hole until the second limiting portion is located in the accommodating cavity and the pressing portion is in contact with the contact member. Then, the connecting portion is released, and the connecting portion is reset to the expanded diameter state under the action of its own elastic force. The installation operation is simple and convenient, and can greatly improve the installation efficiency of the key body.

[0027] The utility model provides a hand-held blender, comprising:

[0028] handle;

[0029] A driver, the driver being provided on the handle;

[0030] an agitator connected to the output end of the driver and capable of rotating along with the output shaft of the driver;

[0031] a circuit board, the circuit board being disposed on the handle and electrically connected to the driver; and

[0032] In the above-mentioned integrated switch structure, the button body is arranged on the handle in a pressable and movable manner.

[0033] The hand-held blender of the present invention adopts the above-mentioned integrated switch structure. Also, based on the fact that at least two switches are both arranged on the first shell, at least two switches with different functions can be integrated and arranged on the same first shell, thereby forming a modular integrated switch structure. The modular integrated switch structure can be independently manufactured and assembled. After the assembly is completed, the modular integrated switch structure and the circuit board are assembled together on the main production line, which can reduce the construction difficulty. Compared with two independently arranged switches, the integrated switch structure is more convenient to install and can improve the installation efficiency. At the same time, the modular manufacturing of the modular integrated switch structure can improve production efficiency, reduce waste, and reduce production costs, thereby reducing the cost of the integrated switch structure and being more conducive to the promotion and application of the integrated switch structure. In addition, the distance between two adjacent switches of the integrated switch structure is fixed, which facilitates the standardized production of the integrated switch structure and can further reduce the production cost. In addition, the overall structure of the integrated switch structure can be made more compact, thereby reducing the occupied space.

[0034] Beneficial effects of the utility model:

[0035] The integrated switch structure of the present invention includes a first housing and at least two switches, and the functions of the at least two switches are different. For example, one of the switches can be configured to control the opening and closing of the hand-held blender drive, and the other switch can be configured to adjust the speed of the hand-held blender drive. Since the at least two switches are both arranged on the first housing, at least two switches with different functions can be integrated on the same first housing, thereby forming a modular integrated switch structure. The modular integrated switch structure can be independently manufactured and assembled. After assembly, the modular integrated switch structure and the circuit board are assembled together on the main production line, which can reduce construction difficulty. Compared with two independently arranged switches, the integrated switch structure is more convenient to install and can improve installation efficiency. At the same time, the modular manufacturing of the modular integrated switch structure can improve production efficiency, reduce waste, and reduce production costs, thereby reducing the cost of the integrated switch structure and being more conducive to the promotion and application of the integrated switch structure.

DETAILED DESCRIPTION

[0043] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may vary depending on the location and usage of the device. Therefore, these or other directional terms should not be interpreted as restrictive.

[0044] See also Figure 1-Figure 5 , shows an integrated switch structure of a preferred embodiment of the present invention, comprising:

[0045] a first housing 1; and

[0046] At least two switches 2 are provided on the first housing 1 . The functions of the at least two switches 2 are different. The switches 2 are used to control the electrical conduction and disconnection between the switches 2 and the circuit board 7 .

[0047] The integrated switch structure of the present invention includes a first housing 1 and at least two switches 2. The functions of the at least two switches 2 are different. For example, one of the switches 2 can be configured to control the opening and closing of the driver 6 of the hand blender, and the other switch 2 can be configured to adjust the speed of the driver 6 of the hand blender. Since the at least two switches 2 are both provided on the first housing 1, at least two switches 2 with different functions can be integrated on the same first housing 1, thereby forming a modular integrated switch structure. The modular integrated switch structure can be independently manufactured and assembled. After assembly, the modular integrated switch structure and the circuit board 7 are assembled together on the main production line, which can reduce the difficulty of construction. Compared with two independently provided switches 2, the integrated switch structure is more convenient to install and can improve installation efficiency. At the same time, the modular manufacturing of the modular integrated switch structure can improve production efficiency, reduce waste, and reduce production costs, thereby reducing the cost of the integrated switch structure and being more conducive to the promotion and application of the integrated switch structure. In addition, the distance between two adjacent switches 2 of the integrated switch structure is fixed, which facilitates the standardized production of the integrated switch structure, which can further reduce production costs. In addition, the overall structure of the integrated switch structure can be made more compact, thereby reducing the occupied space.

[0048] In one embodiment, the switch 2 comprises:

[0049] Terminal 21, the terminal 21 is provided on the first housing 1, and the terminal 21 is used to electrically connect to the circuit board 7;

[0050] a contact member 22 movably disposed on the first housing 1 , the contact member 22 having a connected state in which it abuts against the terminal 21 to electrically connect the switch 2 and the circuit board 7 , and a separated state in which it is separated from the terminal 21 to electrically disconnect the switch 2 and the circuit board 7 , and the contact member 22 is configured to move from the separated state to the connected state when pressed, and maintain the separated state when not pressed; and

[0051] Elastic member 23 is disposed between contact member 22 and first housing 1 and is used to provide a driving force for contact member 22 to maintain its separation. Because switch 2 comprises terminal 21, contact member 22, and elastic member 23, it has fewer components than microswitch 2, resulting in a simplified structure and lower costs, further facilitating the widespread application of integrated switch structures.

[0052] In one embodiment, the integrated switch structure further includes:

[0053] The second housing 3 has a receiving cavity 31, and the receiving cavity 31 receives the first housing 1;

[0054] At least two button bodies 4 are provided on the second shell 3 in a pressable and movable manner. The button body 4 is configured to overcome the driving force of the elastic member 23 when pressed and drive the contact member 22 on the corresponding switch 2 to switch from a separated state to a connected state. In this way, the button body 4 can be maintained in an unpressed state under the action of the elastic member 23. Therefore, there is no need to set an elastic structure between the button body 4 and the contact member 22, which reduces the number of parts and simplifies the structure. While improving the installation efficiency, it can also reduce costs and is more conducive to the promotion and application of the integrated switch structure.

[0055] See also Figure 4 In one embodiment, the switch 2 further includes a push cap 24 movably disposed on the first housing 1 . The push cap 24 is located between the key body 4 and the contact 22 , and is connected to the contact 22 . The push cap 24 moves with the key body 4 to drive the contact 22 from a disconnected state to a connected state. The push cap 24 is made of an insulating material. The provision of the push cap 24 provides insulation, ensuring safe operation.

[0056] See also Figure 4 In one embodiment, the first housing 1 has an inner cavity 11 and a first guide hole 12 , and the first guide hole 12 is connected to the inner cavity 11 ;

[0057] Part of the terminal 21, the contact piece 22 and the elastic piece 23 are all located in the inner cavity 11, and the rest of the terminal 21 is exposed to the first shell 1 and is used to be electrically connected to the circuit board 7. The pressing cap 24 can be movably passed through the first guide hole 12, and the pressing cap 24 is provided with a first limiting portion 242. The outer diameter of the first limiting portion 242 is larger than the aperture of the first guide hole 12. The first limiting portion 242 can be against the cavity wall of the inner cavity 11 to limit the pressing cap 24 from being separated from the first guide hole 12. Among them, since part of the terminal 21, the contact piece 22 and the elastic piece 23 are all located in the inner cavity 11, the part of the terminal 21, the contact piece 22 and the elastic piece 23 can be built into the first shell 1, so that the part of the terminal 21, the contact piece 22 and the elastic piece 23 are protected from the influence of the external environment, such as dust, moisture and chemicals. At the same time, it helps to fix the terminal 21, the contact piece 22 and the elastic piece 23 to prevent the terminal 21, the contact piece 22 and the elastic piece 23 from being displaced or damaged when subjected to external force. At the same time, by cooperating with the first guide hole 12, the pressing cap 24 can be guided to move, so that the pressing cap 24 moves more smoothly and avoids jamming. In addition, the first limiting portion 242 is abutted against the cavity wall of the inner cavity 11 to limit the pressing cap 24 from disengaging from the first guide hole 12, so that the pressing cap 24 can be reliably installed on the first shell 1. The structure is simple and practical, the cost is low, and the reliability is high.

[0058] See also Figure 4In one embodiment, the push cap 24 has a slot 241 on the side facing away from the button body 4, and the contact 22 is provided with a snap-in protrusion 221. The snap-in protrusion 221 snaps into the slot 241 to connect the push cap 24 and the contact 22 together. Thus, by snapping the snap-in protrusion 221 into the slot 241, the push cap 24 and the contact 22 can be installed together. This makes the installation operation simple and convenient, and can improve installation efficiency. At the same time, because the snap-in protrusion 221 is located in the slot 241, the contact 22 is partially embedded in the push cap 24, which can shorten the structural length of the push cap 24 and contact 22 after they are installed together, thereby making the modular integrated switch structure more compact and taking up less space.

[0059] Of course, in other embodiments, the pressing cap 24 and the contact member 22 may also be connected together by screw connection, fastener connection, etc.

[0060] See also Figure 4 In one embodiment, the contact member 22 further includes a contact portion 223. The contact portion 223 is disposed around the engaging protrusion 221, and the contact portion 223 abuts or separates from the terminal 21. Since the contact portion 223 is disposed around the engaging protrusion 221, the surface area of ​​the contact portion 223 is increased. The contact portion 223 with a larger surface area abuts the terminal 21, thereby increasing the contact area between the contact member 22 and the terminal 21. This ensures reliable electrical conduction between the switch 2 and the circuit board 7, and enhances structural reliability.

[0061] See also Figure 4 In one embodiment, the first housing 1 has a first connecting groove 13 , the first connecting groove 13 is located in the inner cavity 11 , and the contact member 22 has a second connecting groove 222 ;

[0062] One end of the elastic member 23 is inserted into the first connecting groove 13, and the other end of the elastic member 23 is inserted into the second connecting groove 222. In this way, during installation, the elastic member 23 can be connected to the first housing 1 and the contact member 22 by inserting one end of the elastic member 23 into the first connecting groove 13 and the other end into the second connecting groove 222. The installation operation is simple and convenient, which can improve the installation efficiency and improve the connection reliability. At the same time, because one end of the elastic member 23 is built into the first housing 1 and the other end of the elastic member 23 is built into the contact member 22, the structural length of the first housing 1, elastic member 23 and contact member 22 after they are installed together can be shortened, thereby making the modular integrated switch structure more compact and taking up less space.

[0063] Of course, in other embodiments, the elastic member 23 may also be connected to the first housing 1 and the contact member 22 by welding, gluing, fastener connection, etc.

[0064] In one embodiment, the elastic member 23 is a spring. The spring has good elasticity and can provide a sufficiently large driving force to the contact member 22 to ensure that the contact member 22 can be reliably maintained in the separated state.

[0065] Of course, in other embodiments, the elastic member 23 may also be a spring, a reed, or other structures, as long as it can provide a sufficiently large driving force to the contact member 22 .

[0066] See also Figure 1-Figure 2 In one embodiment, the second housing 3 has a second guide hole 32 , and the second guide hole 32 is connected to the accommodating cavity 31 ;

[0067] The button body 4 is provided with a pressing portion 41, a connecting portion 42 and a pressing portion 43. The pressing portion 41 is exposed on the second shell 3. The connecting portion 42 is connected to the pressing portion 41 and is arranged around the pressing portion 43. The connecting portion 42 is movably provided with a second guide hole 32. The end of the connecting portion 42 away from the pressing portion 41 is provided with a second limiting portion 421. The second limiting portion 421 is located in the accommodating cavity 31. The outer diameter of the second limiting portion 421 is larger than the aperture of the second guide hole 32. The second limiting portion 421 can be abutted against the cavity wall of the accommodating cavity 31 to limit the connecting portion 42 from being separated from the second guide hole 32. One end of the pressing portion 43 is connected to the pressing portion 41, and the other end of the pressing portion 43 is abutted against the contact member 22. Since the accommodating cavity 31 accommodates the first shell 1, the modular integrated switch structure can be built into the second shell 3, so that the modular integrated switch structure is protected from the influence of the external environment, that is, it plays a role in protecting the modular integrated switch structure. In addition, since the connecting portion 42 of the key body 4 cooperates with the second guide hole 32, the key body 4 can be guided to move, so that the key body 4 moves more smoothly and stably, avoids jamming, and has a better operating feel. In addition, since the second limiting portion 421 is located in the accommodating cavity 31, the outer diameter of the second limiting portion 421 is larger than the aperture of the second guide hole 32, and the second limiting portion 421 can be offset against the cavity wall of the accommodating cavity 31, it is possible to limit the connection portion 42 from being disengaged from the second guide hole 32, thereby realizing that the key body 4 can be reliably installed on the second shell 3. The structure is simple and practical, the cost is low, and the connection reliability is high.

[0068] In one embodiment, the connecting portion 42 is spaced apart from the pressing portion 43. The connecting portion 42 has a reduced diameter state, which moves toward the pressing portion 43 to allow the second limiting portion 421 to enter and exit the second guide hole 32. The connecting portion 42 also has an expanded diameter state, which expands away from the pressing portion 43 to prevent the second limiting portion 421 from leaving the accommodating cavity 31. The connecting portion 42 is elastic, so that the connecting portion 42 can maintain the expanded diameter state. In this way, during installation, the connecting portion 42 can be switched from the expanded diameter state to the reduced diameter state by pinching the connecting portion 42 with fingers, and then the connecting portion 42 is passed through the second guide hole 32 until the second limiting portion 421 is located in the accommodating cavity 31 and the pressing portion 43 abuts against the contact member 22. The connecting portion 42 is then released, and the connecting portion 42 can be restored to the expanded diameter state under the action of its own elastic force. The installation operation is simple and convenient, and the installation efficiency of the key body 4 can be greatly improved.

[0069] In one embodiment, the second shell 3 has an installation groove, which is arranged around the second guide hole 32 and is connected to the second guide hole 32. The integrated switch structure also has a flexible press cover 5, which is adapted to the installation groove to cover the button body 4, which can protect the button body 4 and at the same time improve the feel of the pressing operation.

[0070] In one embodiment, the key body 4 is a structure made of plastic material, so that the key body 4 has better hardness and certain elasticity, so that the connecting part 42 has certain elasticity, ensuring that the connecting part 42 can maintain an expanded diameter state. At the same time, the key body 4 has insulating properties, thereby improving operational safety.

[0071] The utility model provides a hand-held blender, comprising:

[0072] A handle, which is integrally provided with the second housing 3;

[0073] Driver 6, driver 6 is provided on the handle;

[0074] A stirrer is connected to the output end of the driver 6 and can rotate along with the output shaft of the driver 6;

[0075] A circuit board 7 is provided on the handle and is electrically connected to the driver 6; and

[0076] In the above-mentioned integrated switch structure, the button body 4 is arranged on the handle in a pressable and movable manner.

[0077] The hand-held blender of the present invention adopts the above-mentioned integrated switch structure. Also, based on the fact that at least two switches 2 are both arranged on the first shell 1, at least two switches 2 with different functions can be integrated and arranged on the same first shell 1, thereby forming a modular integrated switch structure. The modular integrated switch structure can be independently manufactured and assembled. After the assembly is completed, the modular integrated switch structure and the circuit board 7 are assembled together on the main production line, which can reduce the construction difficulty. Compared with two independently arranged switches 2, the integrated switch structure is more convenient to install and can improve the installation efficiency. At the same time, the modular manufacturing of the modular integrated switch structure can improve production efficiency, reduce waste, and reduce production costs, thereby reducing the cost of the integrated switch structure and being more conducive to the promotion and application of the integrated switch structure. In addition, the distance between two adjacent switches 2 of the integrated switch structure is fixed, which facilitates the standardized production of the integrated switch structure and can further reduce the production cost. In addition, the overall structure of the integrated switch structure can be made more compact, thereby reducing the occupied space.

[0078] According to the above scheme, refer to Figure 5 As shown in the circuit diagram, the working principle of the hand blender is:

[0079] 1. By pressing one of the button bodies 4, the corresponding pressing cap 24 is pushed to move. The pressing cap 24 moves and compresses the elastic member 23 so that the contact member 22 abuts against the terminal 21, thereby realizing a path and providing it to the control end of the driver 6, thereby realizing function one, such as turning on the driver 6.

[0080] 2. By pressing another button body 4, the corresponding pressing cap 24 is pushed to move. The pressing cap 24 moves and compresses the elastic member 23 so that the contact member 22 abuts against the terminal 21, thereby realizing a passage and giving it to the control end of the driver 6, thereby realizing function 2, such as realizing speed regulation of the driver 6.

[0081] 3. By pressing the two button bodies 4 at the same time, the two pressing caps 24 are pushed to move at the same time. The pressing caps 24 move and compress the elastic member 23 so that the contact member 22 contacts the terminal 21, thereby completing the passage and providing it to the control end of the driver 6, thereby achieving function 2.

[0082] 4. On the contrary, the elastic member 23 resets the contact member 22 and separates it from the terminal 21, thereby disconnecting the circuit and realizing the power-off function of the driver 6.

[0083] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
