Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a blender with integrated switch function. Background Technology

[0002] A high-speed blender combines the functions of a juicer, soy milk maker, ice cream maker, food processor, and grinder, offering multiple uses in one machine. It's a machine that can quickly break down the cell walls of food, releasing phytochemicals. Existing high-speed blenders mainly consist of a blending cup, blade assembly, and lid. Typically, the fruits and vegetables to be blended are chopped and placed in the blending cup. During blending, the lid is screwed onto the blending cup, and then a switch on the base is turned on to initiate the blending operation. To ensure the product operates only when the lid is screwed on, existing high-speed blenders use a microswitch between the cup and the lid. However, microswitches are prone to mechanical wear, leading to seal failure and switch malfunction, and also suffer from low current handling capacity, weak vibration / shock resistance, and short electrical life. Alternatively, another triggering method... By installing a spring switch connected to the power circuit on the side wall of the handle of the blending cup, and correspondingly providing a conductive push rod on the cup lid, this spring switch has a socket suitable for inserting the guide push rod and two metal springs set in the socket. The purpose of conducting the power circuit is achieved by inserting the conductive push rod into the socket and connecting the two metal springs. From the above structure, it can be seen that the existing blenders using spring switches have the following problems: the spring switches lack effective sealing and waterproofing measures. When the blender is in use, water and other liquids can easily enter the socket of the spring switch, leading to the risk of short circuit in the contact spring switch, resulting in poor protection. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the problem that in the prior art, when using a blender, liquids such as water can easily enter the socket of the contact spring switch, resulting in a short circuit of the contact spring switch and poor protection.

[0004] To solve the above-mentioned technical problems, this utility model provides a blender with an integrated switch function, including a cup body, a cup lid, and a trigger switch installed in the built-in cavity of the cup body handle. The trigger switch is connected to the power line of the blender. The built-in cavity has an opening groove on one side of the cup body handle. The trigger switch includes a guide cavity communicating with the opening groove, an elastic button reciprocatingly disposed in the guide cavity, and a contact component connected to the elastic button. The top of the elastic button protrudes from or is disposed opposite to the opening groove. At least one layer of sealing material is provided between the elastic button and the inner wall of the guide cavity. The cup lid is provided with a drive rod for driving the elastic button. The trigger switch is turned on and connects the power line when the elastic button is pressed by the drive rod, and is turned off and disconnects the power line when the elastic button is separated from the drive rod.

[0005] As a preferred embodiment, the trigger switch includes a switch housing with a guide cavity, the opening of which is located on the side wall of the switch housing that blocks the opening groove and is opposite to the opening groove, and the sealing element is a sealing ring fitted onto the elastic button near the opening.

[0006] As a preferred embodiment, the elastic button includes a button body and a button spring connected and disposed in the guide cavity. One end of the button spring is connected to the bottom end of the button body, and the other end is disposed in the inner end of the guide cavity away from the cavity opening. The outer peripheral sidewall of the button body is provided with a sealing groove, and the sealing ring is sleeved in the sealing groove and presses against the inner wall of the guide cavity.

[0007] As a preferred embodiment, a limiting structure is provided between the elastic button and the cavity opening. The limiting structure includes a limiting boss disposed on the button body and connected to one side of the sealing groove, and a limiting stop disposed on the inner side of the cavity opening of the guide cavity. The limiting stop and the limiting boss cooperate to abut against each other.

[0008] As a preferred embodiment, the switch housing includes a contact cavity disposed on one side of the guide cavity, the elastic button includes a push portion extending into the contact cavity, and the contact assembly includes a moving contact and a stationary contact disposed in the contact cavity. The moving contact has a spring structure that is bent and extended along the movement path of the push portion and can be elastically deformed under pressure. During the movement of the push portion following the elastic button, the push portion pushes the spring structure to engage or disengage with the stationary contact.

[0009] As a preferred embodiment, a travel groove is provided between the contact cavity and the guide cavity for the movement of the pushing part. The pushing part is a sliding block bent and formed on one side of the button body. The spring structure includes an arc protrusion extending toward the sliding block.

[0010] As a preferred embodiment, the sliding block has an inclined section and a straight section connected on one side of the contact cavity, the straight section extending in a direction parallel to the moving direction of the elastic button.

[0011] As a preferred embodiment, the trigger switch includes a base block embedded in the switch housing, the base block sealing the inner end of the guide cavity, the moving contact and the stationary contact being respectively snapped and fixed on the base block, and each being connected to a connecting wire extending out of the switch housing.

[0012] As a preferred embodiment, the base block is installed inside the switch housing via a positioning structure. The positioning structure includes a positioning hole provided inside the switch housing, and a positioning post correspondingly provided on the base block and inserted into the positioning hole. It also includes a slot provided on the inner wall of the switch housing, and a plug correspondingly provided on the base block and inserted into the slot.

[0013] As a preferred embodiment, the switch housing has an insertion port on its side wall suitable for inserting the base block. The connecting wire passes through the insertion port. The switch housing, the base block, and the connecting wire are sealed with sealant, and a sealant layer covering the base block is filled at the insertion port.

[0014] The technical solution of this utility model has the following advantages:

[0015] 1. In the blender provided by this utility model, the trigger switch is installed in the built-in cavity of the cup handle, and the integrated design utilizes the handle space, resulting in a more compact structural layout. This trigger switch includes a movable elastic button set in the guide cavity, and at least one sealing element is provided between the elastic button and the inner wall of the guide cavity. The sealing element forms a dynamic seal between the elastic button and the guide cavity, preventing water and other liquids from entering the switch even when the cup is soaked in water for cleaning. By physically isolating the internal circuit of the switch from contact with water vapor, the risk of short circuit and leakage is reduced, meeting the safety standards of household appliances and improving the reliability and service life of the switch and the blender as a whole. This blender controls the on / off of the power line by cooperating with the trigger switch in the cup handle through the drive rod on the cup lid. It ensures that the power is only connected when the cup lid is closed in place (the drive rod contacts the elastic button), ensuring safety and preventing accidental start of the blender.

[0016] 2. In the blender provided by this utility model, the sealing ring is fitted into the sealing groove on the outer peripheral side wall of the button body and is set close to the cavity opening. The sealing groove is used to position the sealing ring on the button body, making it difficult for it to shift after installation. The sealing ring is pressed against the inner wall of the guide cavity, increasing the sealing contact area and forming a reliable sealing barrier to prevent it from entering the switch, avoiding short circuit faults, and providing good waterproof performance, thus ensuring the stable operation of the switch and the blender.

[0017] 3. In the blender provided by this utility model, the moving contact utilizes the elastic deformation capability of the spring structure to respond sensitively to pressure changes in the pushing part, enabling timely response to the action of the elastic button. This makes the on / off operation of the switch more sensitive and smooth. Furthermore, the elasticity of the spring structure can buffer the pushing process, reducing mechanical impact, minimizing component wear, and extending the service life of the switch and related structures. This structural design of the moving contact utilizes the elastic deformation capability of the spring structure, resulting in high sensitivity and ensuring stable long-term compression and rebound performance. It also guarantees stable contact pressure, enhances mechanical life and reliability, and allows for flexible customization of the operating force required to trigger the switch by optimizing and adjusting the protrusion height or pre-pressure of the spring structure.

[0018] 4. In the blender provided by this utility model, the pushing part is a sliding block bent and formed on one side of the button body. The sliding block has an inclined section and a straight section connected and arranged on one side of the contact cavity. The inclined section and the straight section respectively press and contact the spring structure of the moving contact piece. With this structure, during the movement of the elastic button, the sliding block first contacts the spring structure through the inclined section. The inclination angle of the inclined section makes the force on the spring structure gradually increase, realizing a smooth elastic deformation. It can more accurately control the contact timing of the moving contact piece and the stationary contact piece, avoid poor contact or component damage caused by instantaneous large pressure impact, and ensure stable power circuit connection. Then, it maintains contact with the spring structure through the straight section, providing stable contact pressure. During the elastic button reset process, it can ensure that the spring structure elastically resets along a predetermined trajectory, so that the moving contact piece is reliably separated from the stationary contact piece, and the power circuit is accurately cut off.

[0019] 5. In the blender provided by this utility model, the side wall of the switch housing is provided with an insertion port suitable for the base block. The moving / stationary contact pieces can be pre-attached to the base block, and then the entire base block insertion port is inserted into the switch housing, simplifying the installation process and improving production efficiency. The base block provides a stable mounting foundation for the moving and stationary contact pieces. By filling the insertion port with sealant, the seam between the base block and the switch housing can be completely covered. The sealant eliminates the liquid penetration path, preventing water and other liquids from entering the switch and avoiding faults such as short circuits. Moreover, the base block, as a rigid carrier, together with the sealant, absorbs external impacts, protecting the internal contact pieces from deformation and breakage. This trigger switch, through the pre-installed base block and fully encapsulated sealant structure design, and in conjunction with the sealant at the elastic button, forms a multi-layer seal, improving the product's protection level.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Example 1

[0032] The following is a detailed description of this embodiment with reference to the accompanying drawings:

[0033] This embodiment provides, as follows: Figure 1-5 The blender shown includes a cup body 1, a cup lid 2, and a trigger switch 3 installed in the built-in cavity of the cup body handle 11. The cup lid 2 is rotatably connected to the cup body 1. The trigger switch 3 is connected to the power line of the blender and is used to control the on / off state of the power line. The built-in cavity has an opening groove 12 on one side of the cup body handle 11. The trigger switch 3 includes a guide cavity 32 communicating with the opening groove 12 and an elastic button 31 reciprocatingly disposed in the guide cavity 32, as well as a contact component connected to the elastic button 31. The top of the elastic button 31 protrudes from the opening groove 12 or is disposed opposite to the opening groove 12. At least one layer of sealing material 33 is provided between the elastic button 31 and the inner wall of the guide cavity 32. The cup lid 2 is provided with a drive rod 9 for driving the elastic button 31. The trigger switch 3 is turned on and connects the power line when the elastic button 31 is pressed by the drive rod 9, and is turned off and disconnects the power line when the elastic button 31 is separated from the drive rod 9.

[0034] In the above embodiment, the trigger switch 3 is installed in the built-in cavity of the cup handle 11, and the integrated design utilizes the handle space, resulting in a more compact structural layout. This trigger switch 3 includes an elastic button 31 that is movable in the guide cavity 32, and at least one sealing element 33 is provided between the elastic button 31 and the inner wall of the guide cavity 32. The sealing element 33 forms a dynamic seal between the elastic button 31 and the guide cavity 32, preventing water and other liquids from entering the switch even when the cup is soaked in water for cleaning. By physically isolating the internal circuit of the switch from water vapor, the risk of short circuit and leakage is reduced, meeting the safety standards for household appliances (reaching an IPX7 waterproof rating). This improves the reliability and service life of the switch and the blender as a whole. This blender controls the on / off of the power line by cooperating with the drive rod 9 on the cup lid 2 and the trigger switch 3 in the cup handle, ensuring that the power is only connected when the cup lid 2 is closed (the drive rod 9 contacts the elastic button 31), ensuring safety and preventing accidental activation of the blender.

[0035] The following is combined Figure 3-5 The specific configuration of the elastic button 31 and the seal 33 is explained in detail below:

[0036] The trigger switch 3 includes a switch housing 30 with a guide cavity 32. The opening of the guide cavity 32 is located on the side wall of the switch housing 30 that blocks the opening groove 12 and is opposite to the opening groove 12. The sealing member 33 is a sealing ring fitted onto the elastic button 31 near the opening. When the cup lid 2 is closed and rotated, it will drive the drive rod 9 to insert into the opening groove 12 and squeeze the elastic button 31, thereby driving the trigger switch 3 to act. Further preferably, the elastic button 31 includes a button body 311 and a button spring 312 connected in the guide cavity 32. One end of the button spring 312 is connected to the bottom end of the button body 311. Its other end is located at the inner end of the guide cavity 32 away from the cavity opening. The button spring 312 applies an elastic force to the button body 311 to move towards the cavity opening, which is used to realize the reset function of the button body 311. The outer peripheral side wall of the button body 311 is provided with a sealing groove. The sealing groove is used to position the sealing ring on the button body 311, so that it is not easy to move after installation. The sealing ring is fitted in the sealing groove and squeezes and contacts the inner wall of the guide cavity 32, increasing the sealing contact area and forming a reliable sealing barrier. It can accurately block water and other liquids splashed in from the direction of the opening groove 12, prevent them from entering the switch, avoid short circuit failure, have good waterproof performance, and ensure the stable operation of the switch and the blender.

[0037] To prevent the button body 311 from dislodging from the guide cavity 32 under the action of the button spring 312, such as Figure 3As shown, a limiting structure is provided between the elastic button 31 and the cavity opening. The limiting structure includes a limiting boss 34 disposed on the button body 311 and connected to one side of the sealing groove, and a limiting stop disposed on the inner side of the cavity opening of the guide cavity 32. The limiting stop and the limiting boss 34 cooperate to limit the elastic button 31 in the guide cavity 32, ensuring that one end of the elastic button 31 is exactly accommodated in the cavity opening of the guide cavity 32.

[0038] Next, let's combine... Figure 1-4 The specific structure of trigger switch 3 is described in detail below:

[0039] The switch housing 30 includes a contact cavity disposed on one side of the guide cavity 32. The elastic button 31 includes a push part 4 extending into the contact cavity. The contact assembly includes a moving contact piece 5 and a stationary contact piece 6 disposed in the contact cavity. The moving contact piece 5 has a spring structure 51 that is bent and extended along the movement path of the push part 4 and can be elastically deformed under pressure. The spring structure 51 is provided with a moving contact, and a corresponding stationary contact is provided on the stationary contact piece 6. As the push part 4 moves along with the elastic button 31, it pushes the spring structure 51 to engage or disengage with the stationary contact piece 6, thereby achieving reliable power circuit connection and disconnection and reducing faults such as poor contact. The advantage of this design is that by placing the contact component in the contact cavity on one side of the guide cavity 32 and using it in conjunction with the elastic button 31, space is fully utilized, making the overall structure of the trigger switch compact and easy to install in the limited space of the blender cup handle. The moving contact 5 utilizes the elastic deformation capability of the spring structure 51 to respond sensitively to pressure changes in the pushing part 4, enabling timely response to the action of the elastic button 31. This makes the switch operation more sensitive and smooth. Furthermore, the elastic action of the spring structure 51 acts as a buffer during the pushing process of the pushing part 4, reducing mechanical impact, minimizing component wear, and extending the service life of the switch and related structures. This structural design of the moving contact 5, utilizing the elastic deformation capability of the spring structure 51, results in high sensitivity, ensuring stable long-term compression and rebound performance, guaranteeing stable contact pressure, and enhancing mechanical life and reliability.

[0040] In a further preferred configuration, a travel groove is provided between the contact cavity and the guide cavity 32 for the pusher 4 to move. The pusher 4 is a sliding block bent and formed on one side of the button body 311. The spring structure 51 includes an arc protrusion extending toward the sliding block. By optimizing and adjusting the protrusion height or pre-pressure of the spring structure 51, the operating force required for switch triggering can be flexibly customized. The sliding block has a sloped section 41 and a straight section 42 connected and arranged on one side of the contact cavity. The extension direction of the straight section 42 is parallel to the movement direction of the elastic button 31. In this structural configuration, during the movement of the elastic button 31, the sliding block first contacts the spring structure 51 via the inclined section 41. The inclination angle of the inclined section gradually increases the force on the spring structure 51, achieving smooth elastic deformation. This allows for more precise control of the contact timing between the moving contact 5 and the stationary contact 6, avoiding poor contact or component damage caused by sudden high pressure impacts, and ensuring stable power circuit connection. Then, the sliding block maintains contact with the spring structure 51 via the straight section 42, providing stable contact pressure. During the reset process of the elastic button 31, this ensures that the spring structure 51 elastically resets along a predetermined trajectory, reliably separating the moving contact 5 from the stationary contact 6, and accurately cutting off the power circuit.

[0041] The trigger switch 3 provided in this embodiment includes a base block 7 embedded in the switch housing 30, as shown in the reference. Figure 3-5 The base block 7 seals the inner end of the guide cavity 32, meaning one end of the button spring 312 abuts against the base block 7. The moving contact 5 and the stationary contact 6 are respectively snapped and fixed onto the base block 7 and are respectively connected to connecting lines 35 extending out of the switch housing 30. The base block 7 provides a stable mounting foundation for the moving contact 5 and the stationary contact 6 within the switch housing 30. The base block 7 is installed within the switch housing 30 via a positioning structure. The positioning structure includes a positioning hole 36 within the switch housing 30, and a positioning post 71 correspondingly positioned on the base block 7 and inserted into the positioning hole 36. It also includes a slot 37 on the inner wall of the switch housing 30, and a plug 72 correspondingly positioned on the base block 7 and inserted into the slot 37. The positioning and installation of the base block 7 within the switch housing 30 are achieved through the cooperation of the positioning post 71 with the positioning hole 36 and the plug 72 with the slot 37, resulting in stable and reliable installation and improved installation efficiency.

[0042] Further optimized settings, such as Figure 4As shown, the switch housing 30 has an insertion port 38 on its side wall, which is suitable for inserting the base block 7. The connecting wire 35 passes through the insertion port 38. The switch housing 30, the base block 7 and the connecting wire 35 are sealed with sealant. The sealant layer 8 is filled in the insertion port 38 and seals the base block 7. This structural design allows the moving / stationary contacts 6 to be pre-attached to the base block 7, and then the entire base block 7 is inserted into the switch housing 30 through the inlet 38. This simplifies the installation process and improves production efficiency. The base block 7 provides a stable mounting foundation for the moving contact 5 and the stationary contact 6. By filling the inlet with sealant, the joint between the base block 7 and the switch housing 30 can be completely covered. The sealant eliminates liquid penetration paths, preventing water and other liquids from entering the switch and avoiding faults such as short circuits. Moreover, the base block, as a rigid carrier, works with the sealant to absorb external impacts, protecting the internal contacts from deformation and breakage. This trigger switch, through its pre-installed base block and fully encapsulated sealant design, and in conjunction with the sealant at the elastic button, forms multiple seals, enhancing the product's protection level.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
