Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a main unit with good waterproof performance and a food processing machine. Background Technology

[0002] Existing food processors, such as meat grinders, typically consist of a main unit with a built-in motor and a processing cup detachably connected to the main unit and containing a grinding device. When using the food processor, the user places the ingredients into the processing cup and places the main unit above it. The grinding device, driven by the motor, rotates at high speed to process the ingredients. To power the motor, a power cord usually passes through the main unit's housing and connects to the motor. However, the motor and power cord are generally soldered, resulting in a weak connection. When the user moves or transports the food processor, the power cord can easily be pulled, and under significant stress, it can detach from the motor, causing the motor to lose power and rendering the entire machine unusable. To improve the stability of the power cord's position, Chinese patent CN202123452637.9 discloses a food processor main unit and food processor. This design features a downward-facing upper opening at the bottom of the main unit housing and an upward-facing lower opening on the base. A tail clip is also provided on the power cord. When the housing and base are installed, the upper and lower openings engage with the tail clip's slots to limit the power cord's movement and prevent it from detaching from the main unit. However, users have found that during cleaning, water can easily enter the main unit through the gaps between the upper and lower openings and the tail clip. This can cause electrical components inside, such as circuit boards, to become damp, short-circuit, or even be damaged, rendering the food processor unusable and severely impacting the user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a main unit and food processing machine with good waterproof performance, so as to solve the problem of how to prevent water stains from entering the main unit through the gap between the tail clip and the housing and causing damage to the electrical components inside the main unit, while ensuring the stability of the main unit by setting a tail clip on the power cord and locking it with the housing.

[0004] To achieve the above objectives, this utility model provides a waterproof host, including a motor and a power cord electrically connected to the motor. The host also includes a first housing and a second housing for accommodating the motor. The first housing and the second housing are fixedly connected axially to form a receiving cavity for accommodating the motor. The first housing has a mounting cavity with an opening facing the second housing. The mounting cavity is located near the connection between the first housing and the second housing. The inner and outer walls of the mounting cavity are respectively provided with a first fixing groove and a second fixing groove that extend axially and open towards the second housing. The power cord has a radially protruding tail clip. The slot of the tail clip is inserted into the second fixing groove, and the power cord passes through the first fixing groove and is electrically connected to the motor. The mounting cavity also has a sealing element embedded in the opening of the mounting cavity. The second housing abuts against the sealing element to press and seal the tail clip in the mounting cavity. The sealing element radially abuts against the radially inner side of the mating gap formed by the axial fixing of the first housing and the second housing.

[0005] This application provides a mounting cavity with an opening facing the second housing in the first housing. The inner and outer walls of the mounting cavity are respectively provided with a first fixing groove and a second fixing groove that extend axially and open towards the second housing. The slot of the power cord's tail clip is inserted into the second fixing groove, so that the power cord is firmly fixed by the engagement between the slot of the tail clip and the second mounting groove. This effectively limits the position of the power cord, ensures the stability of the power cord's position, and prevents the power cord from becoming loose or even falling off the motor when the user pulls on it. Simultaneously, a sealing element is also provided inside the installation cavity, located below the tail clip. The second housing abuts against the sealing element to press and seal the tail clip within the installation cavity. After the first and second housings are connected and fixed, the second housing can abut against the sealing element and squeeze the sealing element towards the tail clip. Utilizing the elastic deformation of the sealing element, a reliable sealing structure is formed between the sealing element and the tail clip, and between the sealing element and the second housing. When water enters through the joint gap between the first and second housings, the radial abutment of the sealing element against the joint gap formed by the axial fixation of the first and second housings creates the first layer of waterproof sealing. Simultaneously, the sealing element allows water to enter the main unit through the circumferential gap of the tail clip's slot, causing the path of water entering the installation cavity to become more winding and tortuous, thus forming a second layer of waterproof sealing. This isolates the installation cavity from the outside environment, effectively preventing external water from entering the main unit through the gap between the tail clip and the first or second housing, which could lead to moisture damage, short circuits, or even failure of the electrical components inside the main unit. This achieves waterproof sealing of the main unit, ensuring the safe operation of the electrical components inside, extending their service life, and improving the user experience.

[0006] In a preferred embodiment of a waterproof host, the first housing has a C-shaped cavity with an opening facing the second housing, the second housing has a C-shaped rib inserted into the C-shaped cavity, and the C-shaped cavity is connected to the mounting cavity to form a circumferentially closed annular cavity facing the opening of the second housing.

[0007] By providing a C-shaped cavity with an opening facing the second housing, and a C-shaped rib inserted into the C-shaped cavity in the second housing, the C-shaped cavity is connected to the mounting cavity to form a circumferentially closed annular cavity facing the opening of the second housing. On the one hand, after the first and second housings are installed and fixed, a tortuous waterproof path can be formed between the C-shaped rib and the C-shaped cavity, thereby effectively preventing external water stains from directly entering the main unit through the gap between the first and second housings. Combined with the sealing of the mounting cavity by the sealing element, all-round waterproof sealing is achieved at the connection position of the first and second housings, further improving the overall waterproof performance of the main unit. On the other hand, when assembling the first and second housings, the insertion and cooperation of the C-shaped rib and the C-shaped cavity can achieve precise alignment of the first and second housings, improving assembly efficiency and assembly accuracy, ensuring that all components fit tightly, and further enhancing the structural stability and waterproof reliability of the main unit.

[0008] In a preferred embodiment of a main unit with good waterproof performance, the sealing element includes a main body and a sealing rib that protrudes radially outward from the main body. The two ends of the sealing rib are located at the two ends of the C-shaped cavity and the mounting cavity, and the C-shaped rib is provided with a first clearance notch to avoid the sealing rib.

[0009] By configuring the seal as including a body portion and sealing ribs protruding radially outward from the body portion, with both ends of the sealing ribs located at the ends communicating with the C-shaped cavity and the mounting cavity, the seal can effectively seal the mounting cavity through the body portion, and simultaneously block the communication between the C-shaped cavity and the mounting cavity through the sealing ribs, thereby further improving the sealing effect on the mounting cavity. At the same time, the C-shaped ribs are provided with a first clearance notch to avoid the sealing ribs, allowing the C-shaped ribs to smoothly pass through the sealing ribs during the assembly of the first and second housings. This ensures that the C-shaped ribs can be fully inserted into the C-shaped cavity, thereby guaranteeing a tight connection between the first and second housings and preventing sealing failure due to improper assembly.

[0010] In a preferred embodiment of a waterproof host, a sealing ring is provided inside the C-shaped cavity. The sealing ring has a second clearance notch to avoid the mounting cavity. The two ends of the sealing ring abut against the two circumferential sides of the sealing element, and the C-shaped rib is inserted into the C-shaped cavity to hold the sealing ring.

[0011] A sealing ring is also provided within the C-shaped cavity, and a C-shaped rib is inserted into the C-shaped cavity to hold the sealing ring in place. After the first and second housings are installed, the sealing ring is clamped between the C-shaped rib and the C-shaped cavity, effectively sealing the gap between the C-shaped rib and the C-shaped cavity. This achieves a more comprehensive sealing effect, effectively preventing external water stains from seeping into the main unit through the gap between the C-shaped rib and the C-shaped cavity. Furthermore, the sealing ring has a second clearance notch to avoid the installation cavity. Both ends of the sealing ring abut against the circumferential sides of the sealing element, ensuring that the sealing ring can be smoothly installed into the C-shaped cavity. Simultaneously, the two ends of the sealing ring abut against the sealing element, sealing the joint between the installation cavity and the C-shaped cavity, further improving the sealing effect of the installation cavity. At the same time, after the sealing ring abuts against the sealing element, it can achieve radial limiting of the sealing element, ensuring the stability of the sealing element's position, thus guaranteeing the sealing reliability of the sealing element to the tail clip and the installation cavity. It also achieves a comprehensive seal of the entire annular cavity area, further improving the waterproof performance of the main unit.

[0012] In a preferred embodiment of a waterproof host, the sealing element includes a body portion and sealing rings extending outward from both circumferential sides of the body portion, with C-shaped ribs inserted into the C-shaped cavities to hold the sealing rings.

[0013] By configuring the seal as a body portion and sealing rings extending outward from both circumferential sides of the body portion, with C-shaped ribs inserted into the C-shaped cavity to hold the sealing rings, the seal can effectively seal the mounting cavity not only through the body portion but also through the sealing rings, achieving all-around waterproof sealing at the connection between the first and second housings, further enhancing the waterproof performance of the main unit. Simultaneously, the body portion and the sealing ring are a single integral piece, effectively preventing gaps between them from allowing water stains to enter the main unit, thus further improving the overall waterproof sealing performance of the device.

[0014] In a preferred embodiment of a waterproof host, the second housing is provided with a protruding plate extending into the second fixing groove, and the protruding plate abuts against the slot of the tail clip.

[0015] By providing a protruding plate extending into the second fixing groove in the second housing, and having the protruding plate abut against the slot of the tail clip, on the one hand, the protruding plate can block the outside of the second fixing groove, thereby sealing the entire second fixing groove and preventing external water stains or other impurities from entering the second fixing groove; on the other hand, the tight abutment between the protruding plate and the slot of the tail clip enhances the connection stability between the second housing and the tail clip, further improving the fixing effect of the tail clip, and also improving the sealing between the second housing and the tail clip, ensuring the waterproof effect of the whole machine.

[0016] In a preferred embodiment of a main unit with good waterproof performance, a clearance channel is provided on one side of the outer radial side of the seal, which extends axially along the first housing to avoid the protruding plate, and the inner wall of the protruding plate abuts radially with the clearance channel.

[0017] By providing a clearance channel on one radially outer side of the seal, which extends axially along the first housing to avoid the protruding plate, the protruding plate can smoothly pass through the clearance channel and abut against the slot of the tail clip during the assembly of the first and second housings. This ensures that the first and second housings can be smoothly assembled into place. At the same time, the inner wall of the protruding plate abuts radially against the clearance channel to form an additional sealing layer between the protruding plate and the clearance channel, further enhancing the sealing effect of the seal. It also enables radial limiting of the seal, ensuring the stability of the seal position and preventing the seal from shifting due to vibration during the operation of the host, thus preventing seal failure. This ensures that the host maintains excellent waterproof performance in complex environments, extends its service life, and improves the user experience.

[0018] In a preferred embodiment of a waterproof host, adhesive is applied to the first fixing groove to seal the gap between the first fixing groove and the power cord.

[0019] By applying adhesive to the first fixing groove, the gap between the first fixing groove and the power cord is sealed, achieving a complete seal between the first fixing groove and the power cord. A third layer of waterproof sealing is formed at the first fixing groove and the second power cord. Combined with the sealing component, the sealing of the mounting cavity achieves triple sealing protection, greatly improving the overall sealing and waterproofing effect of the machine.

[0020] In a preferred embodiment of a waterproof host, the first housing includes a receiving portion and a connecting portion located below the receiving portion and expanding relative to the outer diameter of the receiving portion. The connecting portion has a radially outwardly protruding convex portion, and the outer wall of the mounting cavity is formed on the convex portion; or,

[0021] The first housing includes a receiving portion and a connecting portion located below the receiving portion and expanding relative to the outer diameter of the receiving portion; the inner wall of the mounting cavity extends downward from the bottom end of the receiving portion; or,

[0022] The first housing is the upper housing, and the second housing is the base that supports the motor.

[0023] As a preferred embodiment of this application, this application also includes a food processing machine, comprising a main unit as described above and a processing cup detachably connected to the main unit and having a built-in crushing device, with the main unit located above the processing cup.

[0024] By applying the main unit as described above to the food processing machine, the main unit can be sealed and waterproofed, ensuring the safe operation of the electrical components inside the main unit, guaranteeing the stability of the entire food processing machine, extending the service life of the equipment, and improving the user experience.

Detailed Implementation

[0038] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0039] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0040] like Figures 1 to 10 As shown, this utility model provides a waterproof host, including a motor 7 and a power cord 3 electrically connected to the motor 7. The host also includes a first housing 1 and a second housing 2 to accommodate the motor 7. The first housing 1 and the second housing 2 are fixedly connected along the axial direction to form a receiving cavity to accommodate the motor 7. The first housing 1 is provided with a mounting cavity 13 with an opening facing the second housing 2. The mounting cavity 13 is located near the connection between the first housing 1 and the second housing 2. The inner side wall and the outer side wall of the mounting cavity 13 are respectively provided with a first fixing groove 132 and a second fixing groove 131 that extend along the axial direction and open towards the second housing 2. The power cord 3 is provided with a radially protruding tail clip 4. The slot 41 of the tail clip 4 is inserted into the second fixing groove 131, and the power cord 3 passes through the first fixing groove 132 and is electrically connected to the motor 7. The mounting cavity 13 is also provided with a sealing member 5 embedded in the opening of the mounting cavity 13. The second housing 2 abuts against the sealing member 5 to press and seal the tail clip 4 in the mounting cavity 13. The sealing member 5 radially abuts against the radial inner side of the mating gap formed by the axial fixing of the first housing 1 and the second housing 2. Even better, the mounting cavity 13 is a convex-shaped cavity, the tail clip 4 is clipped into the first cavity located above through the clip groove, and the sealing element 5 is installed in the radially enlarged second cavity.

[0041] This application provides a mounting cavity 13 with an opening facing the second housing 2 in the first housing 1. The inner and outer walls of the mounting cavity 13 are respectively provided with a first fixing groove 132 and a second fixing groove 131 that extend axially and open towards the second housing 2. The slot 41 of the tail clip 4 of the power cord 3 is inserted into the second fixing groove 131, so that the power cord 3 is firmly fixed by the engagement of the slot 41 of the tail clip 4 with the second mounting groove. This effectively limits the position of the power cord 3, ensures the stability of the position of the power cord 3, and avoids the situation where the power cord 3 becomes loose or even falls off the motor 7 when the user pulls on it. Simultaneously, a sealing element 5 is also provided in the mounting cavity 13, located below the tail clip 4. The second housing 2 abuts against the sealing element 5 to press and seal the tail clip 4 within the mounting cavity 13. After the first housing 1 and the second housing 2 are connected and fixed, the second housing 2 can abut against the sealing element 5 and press the sealing element 5 towards the tail clip 4. With the elastic deformation of the sealing element 5, a reliable sealing structure is formed between the sealing element 5 and the tail clip 4, and between the sealing element 5 and the second housing 2. When water enters through the mating gap between the first housing 1 and the second housing 2, the radial abutment action of the sealing element 5 against the mating gap formed by the axial fixation of the first housing 1 and the second housing 2 forms the first... The first layer of sealing and waterproofing is achieved. Simultaneously, the sealing element 5 allows water stains to enter the main unit through the circumferential gap of the slot 41 of the tail clip 4, and the mating gap between the first housing 1 and the second housing 2 is axially displaced. This makes the path into the mounting cavity 13 more winding and tortuous, thus forming a second layer of sealing and waterproofing. This isolates the mounting cavity 13 from the outside world, effectively preventing external water stains from entering the main unit through the gap between the tail clip 4 and the first housing 1 or the second housing 2, which could cause the electrical components inside the main unit to become damp, short-circuit, or even fail. This achieves sealing and waterproofing of the main unit, ensuring the safe operation of the electrical components inside the main unit, extending their service life, and improving the user experience.

[0042] It should be noted that this application does not specifically limit the structure of the first shell 1 and the second shell 2. As one preferred embodiment of this application, such as... Figure 2 As shown, the first housing 1 is the upper housing, the second housing 2 is the base that supports the motor 7, and the mounting cavity 13 has its opening facing downwards.

[0043] As a preferred embodiment of this application, such as Figure 4 , Figure 5 , Figure 8 As shown, the first housing 1 has a C-shaped cavity 14 with an opening facing the second housing 2, and the second housing 2 has a C-shaped rib 22 inserted into the C-shaped cavity 14. The C-shaped cavity 14 is connected to the mounting cavity 13 to form an annular cavity that is circumferentially closed and opens towards the second housing 2.

[0044] By providing a C-shaped cavity 14 with an opening facing the second housing 2 in the first housing 1, and a C-shaped rib 22 inserted into the C-shaped cavity 14 in the second housing 2, the C-shaped cavity 14 is connected to the mounting cavity 13 to form a circumferentially closed annular cavity facing the opening of the second housing 2. On the one hand, after the first housing 1 and the second housing 2 are installed and fixed, a tortuous waterproof path can be formed between the C-shaped rib 22 and the C-shaped cavity 14, thereby effectively preventing external water stains from directly entering the host through the gap between the first housing 1 and the second housing 2. Combined with the sealing of the mounting cavity 13 by the sealing element 5, all-round sealing and waterproofing at the connection position of the first housing 1 and the second housing 2 are achieved, further improving the overall waterproof performance of the host. On the other hand, when assembling the first housing 1 and the second housing 2, the precise alignment of the first housing 1 and the second housing 2 can be achieved by the insertion and cooperation of the C-shaped rib 22 and the C-shaped cavity 14, improving assembly efficiency and assembly accuracy, ensuring that each component fits tightly, and further enhancing the structural stability and waterproof reliability of the host.

[0045] Furthermore, such as Figure 7 As shown, the sealing member 5 includes a body portion 51 and a sealing rib 52 that protrudes radially outward from the body portion 51. The two ends of the sealing rib 52 are located at the two ends that communicate with the C-shaped cavity 14 and the mounting cavity 13, and the C-shaped rib 22 is provided with a first clearance notch 23 to avoid the sealing rib 52.

[0046] By configuring the sealing element 5 as including a body portion 51 and a sealing rib 52 protruding radially outward from the body portion 51, with both ends of the sealing rib 52 located at the ends communicating between the C-shaped cavity 14 and the mounting cavity 13, the sealing element 5 can effectively seal the mounting cavity 13 through the body portion 51, and simultaneously seal the communication position between the C-shaped cavity 14 and the mounting cavity 13 through the sealing rib 52, thereby further improving the sealing effect on the mounting cavity 13. Meanwhile, the C-shaped rib 22 is provided with a first clearance notch 23 to avoid the sealing rib 52, so that during the assembly of the first housing 1 and the second housing 2, the C-shaped rib 22 can smoothly pass through the sealing rib 52 with the help of the first clearance notch 23, ensuring that the C-shaped rib 22 can be fully inserted into the C-shaped cavity 14, thereby ensuring a tight connection between the first housing 1 and the second housing 2 and avoiding sealing failure due to improper assembly.

[0047] As a preferred embodiment, such as Figure 4 As shown, a sealing ring 6 is also provided in the C-shaped cavity 14. The sealing ring 6 has a second clearance notch to avoid the mounting cavity 13. The two ends of the sealing ring 6 abut against the two circumferential sides of the sealing element 5 respectively. The C-shaped rib 22 is inserted into the C-shaped cavity 14 to hold the sealing ring 6.

[0048] A sealing ring 6 is also provided inside the C-shaped cavity 14, and the C-shaped rib 22 is inserted into the C-shaped cavity 14 to hold the sealing ring 6. After the first housing 1 and the second housing 2 are installed in place, the sealing ring 6 is clamped between the C-shaped rib 22 and the C-shaped cavity 14. The sealing ring 6 is used to seal the gap between the C-shaped rib 22 and the C-shaped cavity 14, thereby achieving a more comprehensive sealing effect and effectively preventing external water stains from seeping into the main unit through the gap between the C-shaped rib 22 and the C-shaped cavity 14. Furthermore, the sealing ring 6 is provided with a second clearance notch to avoid the mounting cavity 13. The two ends of the sealing ring 6 abut against the two circumferential sides of the sealing element 5 respectively. The second clearance notch ensures that the sealing ring 6 can be smoothly installed into the C-shaped cavity 14. At the same time, the two ends of the sealing ring 6 abut against the sealing element 5 to seal the joint between the mounting cavity 13 and the C-shaped cavity 14, thereby further improving the sealing effect of the mounting cavity 13. After the sealing ring 6 abuts against the sealing element 5, it can achieve radial limiting of the sealing element 5, ensuring the stability of the position of the sealing element 5, thereby ensuring the sealing reliability of the sealing element 5 to the tail card 4 and the mounting cavity 13, and achieving a complete seal of the entire area of ​​the annular cavity, further improving the waterproof performance of the main unit.

[0049] As another preferred embodiment of this example, the seal 5 includes a body portion 51 and sealing rings 6 extending outward from both circumferential sides of the body portion 51, with C-shaped ribs 22 inserted into the C-shaped cavity 14 to press the sealing rings 6.

[0050] By configuring the sealing element 5 as including a body portion 51 and sealing rings 6 extending outward from both circumferential sides of the body portion 51, and inserting the C-shaped rib 22 into the C-shaped cavity 14 to press the sealing rings 6, the sealing element 5 can not only effectively seal the mounting cavity 13 through the body portion 51, but also seal the C-shaped cavity 14 through the sealing rings 6, achieving all-round waterproof sealing at the connection position of the first housing 1 and the second housing 2, further improving the waterproof performance of the main unit. At the same time, the body portion and the sealing rings 6 are an integral part, effectively preventing gaps between the two from allowing water stains to enter the main unit through these gaps, which helps to further improve the overall waterproof sealing performance of the machine.

[0051] As a preferred embodiment of this application, such as Figure 2 , Figure 8 As shown, the second housing 2 is provided with a protruding plate 21 extending into the second fixing groove 131, and the protruding plate 21 abuts against the groove 41 of the tail clip 4.

[0052] By providing a protruding plate 21 extending into the second fixing groove 131 in the second housing 2, and having the protruding plate 21 abutting against the slot 41 of the tail clip 4, on the one hand, the protruding plate 21 can block the outside of the second fixing groove 131, thereby sealing the entire second fixing groove 131 and preventing external water stains or other impurities from entering the second fixing groove 131; on the other hand, the tight abutting between the protruding plate 21 and the slot 41 of the tail clip 4 enhances the connection stability between the second housing 2 and the tail clip 4, further improving the fixing effect of the tail clip 4, and also improving the sealing between the second housing 2 and the tail clip 4, ensuring the waterproof effect of the whole machine.

[0053] Furthermore, such as Figure 7 As shown, the seal 5 has a clearance channel 53 on one side of the radially outer side, which extends axially along the first housing 1 to avoid the protruding plate 21. The inner wall of the protruding plate 21 is radially abutted against the clearance channel 53.

[0054] By providing a clearance channel 53 on one radially outer side of the seal 5, which extends axially along the first housing 1 to avoid the protruding plate 21, the protruding plate 21 can smoothly pass through the clearance channel 53 and abut against the slot 41 of the tail clip 4 when the first housing 1 and the second housing 2 are assembled. This ensures that the first housing 1 and the second housing 2 can be smoothly assembled into place. At the same time, the inner wall of the protruding plate 21 abuts radially against the clearance channel 53 to form an additional sealing layer between the protruding plate 21 and the clearance channel 53, further enhancing the sealing effect of the seal 5. It can also achieve radial limiting of the seal 5, ensuring the stability of the seal 5's position and preventing the seal 5 from shifting due to vibration during the operation of the host, thus ensuring that the host maintains excellent waterproof performance in complex environments, extending its service life, and improving the user experience.

[0055] Of course, the second housing 2 in this application is not limited to the above-mentioned configuration. It can also be that the second housing 2 does not have a smooth top surface with a convex plate and the sealing member 5 does not have a clearance channel, so that the first housing 1 and the second housing 2 can be connected and fixed at any angle without considering the connection position of the two, which helps to improve assembly efficiency.

[0056] In a preferred embodiment of this application, the first fixing groove 132 is filled with glue to seal the gap between the first fixing groove 132 and the power line 3.

[0057] By applying adhesive to the first fixing groove 132, the gap between the first fixing groove 132 and the power cord 3 is sealed, achieving a complete seal between the first fixing groove 132 and the power cord 3. A third layer of waterproof sealing is formed at the first fixing groove 132 and the second power cord 3. Combined with the sealing element 5, the sealing of the mounting cavity 13 achieves triple sealing protection, greatly improving the overall sealing and waterproofing effect of the machine.

[0058] As a preferred embodiment of this application, such as Figure 2 As shown, the first housing 1 includes a receiving portion 11 and a connecting portion 12 located below the receiving portion 11 and enlarged relative to the outer diameter of the receiving portion 11. The connecting portion 12 has a radially outward protrusion. The outer wall of the mounting cavity 13 is formed on the protrusion. Specifically, when the first housing 1 is the upper housing and the second housing 2 is the base, the protrusion protrudes radially outward and upward from the top wall of the connecting portion 12.

[0059] In a preferred embodiment of this application, the inner wall of the mounting cavity 13 extends downward from the bottom end of the receiving portion 11.

[0060] Of course, the inner and outer walls of the mounting cavity 13 are not limited to the above-described configuration. They can also be that the first housing 1 is cylindrical, and the outer wall of the mounting cavity 13 is formed on the first housing 1.
