Description

Technical Field

[0001] The utility model belongs to the technical field of food processing devices, and in particular relates to a food processing machine with reliable sealing. Background Art

[0002] Traditional self-cleaning food processors generally include a main unit and a cup body and a drain valve fixed on the main unit to realize automatic pulping and automatic cleaning functions. However, since the valve body and pulp nozzle of the drain valve are fixed on the main unit, users cannot disassemble the pulp nozzle for cleaning, resulting in incomplete cleaning of the drain valve. Moreover, since the cup body cannot be disassembled at will, the multi-functional expansion of the food processor cannot be realized, and its use is limited.

[0003] Based on the continuous research on food processing machines, the applicant has previously applied for a food processing machine with a detachable cup body and a slurry nozzle. The food processing machine includes a support seat with a motor inside, a support platform is provided on the support seat to support the cup body, the cup body is detachably mounted on the support platform, a valve body is fixedly arranged at the bottom of the cup body, and a mounting port is also provided on the support platform. The slurry nozzle is detachably supported on the support platform and is inserted into the mounting port to cooperate with the valve body. This solution can realize the flexible disassembly and assembly of the cup body and the slurry nozzle, so that the slurry nozzle and the cup body can be cleaned thoroughly and used hygienically. At the same time, the slurry nozzle can be installed from top to bottom without complicated alignment, and can be blindly installed, which greatly facilitates user operation.

[0004] However, the applicant found in the further research process that in order to realize the installation of the motor and realize the reliable support of the support platform to the pulp nozzle, the support seat includes a split support seat and a support cover. There is a matching gap between the support seat and the support cover at the position where the installation port is formed. Moreover, the pulp nozzle usually needs to rotate to switch positions. Therefore, there is also a matching gap between the pulp discharge pipe of the pulp nozzle and the installation port. Since the pulp receiving cup and the residual water box are located below the pulp nozzle, after the hot pulp is discharged into the pulp receiving cup, or the hot washing residual water is discharged into the residual water box, the hot steam will flow upward to the installation port. When a large amount of steam is collected at the installation port, it may enter the motor installation cavity of the support seat, making the internal environment of the support seat humid and affecting the service life of the motor. In addition, since the support seat and the support cover are rigidly matched, and the motor has a strong vibration when the load is large during operation, the vibration of the motor will be transmitted to the support seat and the support cover, causing collision noise between the support seat and the support cover, and the noise of the whole machine is large. Utility Model Content

[0005] The utility model provides a food processing machine with reliable sealing, so as to solve the technical problems of steam intrusion risk and unreliable sealing of the main engine seat in the prior art, protect the normal operation of the motor, and realize noise reduction of the whole machine at the same time.

[0006] The technical solution adopted by the utility model is:

[0007] The utility model provides a food processing machine with reliable sealing, comprising a main casing, a main base arranged in the main casing, and a grinding cup detachably mounted above the main base, a valve body being arranged at the bottom of the grinding cup, a pulp nozzle being detachably arranged on the main base, the pulp nozzle being detachably connected to the valve body, the main base comprising a support seat and a support cover which enclose a motor mounting cavity, the support cover being provided with an upper mounting portion which is laterally staggered from the motor mounting cavity and an upper mounting opening arranged on the upper mounting portion, the support seat being provided with a lower mounting portion corresponding to the lower side of the upper mounting portion and a lower mounting opening arranged on the lower mounting portion, the pulp nozzle being inserted through the upper mounting opening and the lower mounting opening, the main base also comprising a sealing gasket clamped between the upper mounting portion and the lower mounting portion, the sealing gasket being arranged around the edge of the lower mounting opening.

[0008] The utility model provides a food processing machine with reliable sealing. The crushing cup is detachably mounted above the main base. The main base is detachably provided with a pulp nozzle, and the pulp nozzle is detachably connected to the valve body, so as to achieve thorough cleaning of the pulp nozzle. At the same time, the cup body can be removed for pouring out after preparing thick slurry to avoid clogging of the pulp nozzle. It is reliable to use and can replace different cup bodies to achieve multi-functional expansion. The main base includes a support base and a support cover that enclose a motor mounting cavity, so as to achieve reliable installation and protection of the motor. An upper mounting portion and an upper mounting port that are laterally staggered from the motor mounting cavity are provided on the support cover, and the support base is provided with a lower mounting portion corresponding to the lower portion of the upper mounting portion and a lower mounting port provided on the lower mounting portion. Therefore, the support base and the support cover integrate the support and limiting functions of the pulp nozzle while realizing the installation function of the motor. The upper mounting portion and the lower mounting portion cooperate to support the pulp nozzle, and the upper mounting port and the lower mounting port cooperate to limit the pulp nozzle, so as to achieve reliable installation and flexible disassembly of the pulp nozzle. On this basis, the main base also includes a sealing gasket clamped between the upper mounting part and the lower mounting part, and the sealing gasket is arranged around the edge of the lower mounting port, so that the matching gap between the upper mounting part and the lower mounting part is reliably sealed. Even if there is a risk of steam entering the matching gap between the slurry nozzle and the mounting port, the sealing gasket can effectively prevent the hot steam generated in the liquid receiving container from further entering the motor mounting cavity laterally, effectively avoiding the increase in temperature and humidity in the motor mounting cavity and causing the insulation of the motor to decrease, protecting the normal operation of the motor and extending the service life of the whole machine. In addition, since the upper mounting part and the lower mounting part need to cooperate and have a certain contact in order to support the slurry nozzle, a sealing gasket is provided to form a flexible contact between the upper mounting part and the lower mounting part. When the motor vibrates during operation, the sealing gasket between the upper mounting part and the lower mounting part absorbs the transmission of vibration, which has the effect of reducing the working noise of the whole machine.

[0009] In a preferred embodiment, the sealing gasket includes a sealing ring surrounding the upper mounting opening and an extension portion protruding outward from the sealing ring, and a limiting structure is provided between the extension portion and the lower mounting portion.

[0010] The sealing gasket includes a sealing ring and an extension part. The sealing ring is used to surround the upper mounting opening to effectively seal the matching gap between the upper mounting part and the lower mounting part, and to laterally block the hot steam generated by the liquid cup body to prevent the steam from entering the motor mounting cavity. By setting the extension part, the extension part can form a gripping part to facilitate the assembly of the sealing gasket by the assembler, and expand the sealing area between the sealing gasket and the lower mounting part to improve the sealing performance. At the same time, a limiting structure is set between the extension part and the lower mounting part to achieve pre-positioning between the sealing gasket and the lower mounting part, which is convenient for rapid installation and subsequent clamping and fixing. In addition, it can avoid the situation where the displacement occurs during the user's use of the food processor after the assembly is completed, which interferes with the rotation of the pulp nozzle.

[0011] In a preferred embodiment, the limiting structure includes a limiting column provided at one of the extension portion and the lower mounting portion and a limiting hole provided at the other of the extension portion and the lower mounting portion, and the limiting column and the limiting hole are plugged in the vertical direction;

[0012] In a preferred embodiment, the limiting structure includes a stud disposed on one of the extension portion and the lower mounting portion and a screw hole disposed on the other of the extension portion and the lower mounting portion, and a screw passes through the screw hole and is locked on the stud;

[0013] In a preferred embodiment, the limiting structure includes a mounting groove provided on the extension portion, and the extension portion is installed in the mounting groove;

[0014] In a preferred embodiment, the limiting structure includes a plurality of limiting ribs protruding from the extending portion, and the limiting ribs are arranged at intervals along the edge of the extending portion.

[0015] Regardless of which of the above-mentioned specific methods is adopted by the limiting structure, the pre-installation positioning of the sealing gasket can be effectively realized, and the sealing gasket can be easily and accurately installed. Specifically, the plug-in method of the limiting column and the limiting hole can provide precise vertical positioning, ensure that the relative position between the extension part and the lower mounting part is accurate, ensure the installation accuracy and stability, and at the same time, the connection strength is large, which improves the stable and reliable installation of the sealing gasket and also has a certain anti-fool effect. Using screws to lock the studs and screw holes can provide a reliable fixed connection to ensure a tight connection between the extension part and the lower mounting part. Installing the extension part in the mounting groove can achieve precise positioning and fixation, and the mounting groove can provide guidance and constraints to ensure that the installation position of the extension part is correct and reduce installation errors. Multiple limiting ribs are arranged at intervals along the edge of the extension part, which can limit the position of the extension part to prevent it from excessive movement or rotation, and maintain the matching stability of the sealing gasket and the lower mounting part while simplifying the structure.

[0016] In a preferred embodiment, the lower mounting portion is provided with an upwardly arched boss, the lower mounting opening is opened on the top surface of the boss, and the boss and the upper mounting portion clamp the sealing gasket.

[0017] By setting a boss that arches upward, it is more difficult for water droplets formed after water vapor condenses to enter the installation opening and the installation gap, thereby further improving the waterproof effect of the main base. The boss and the upper mounting part are used to clamp the sealing gasket, which can clamp the sealing gasket more firmly and fix it reliably.

[0018] In a preferred embodiment, the sealing gasket is provided with at least one circle of upper annular ribs protruding toward the upper mounting portion, and the upper annular ribs abut against the edge of the upper mounting opening.

[0019] In a preferred embodiment, the sealing gasket is provided with at least one circle of lower annular ribs protruding toward the lower mounting portion, and the lower annular ribs abut against the edge of the lower mounting opening.

[0020] By providing an upper ring rib or a lower ring rib on the sealing gasket and utilizing the upper ring rib to abut against the edge of the upper mounting opening, line sealing is achieved compared to directly cooperating between the upper surface of the sealing gasket and the edge of the upper mounting opening, thereby extending the path for the lateral flow of steam. Similarly, line sealing is achieved using the lower ring rib, thereby greatly reducing the probability of steam entering the interior of the main engine base and maintaining a dry environment in the motor mounting cavity.

[0021] In a preferred embodiment, the slurry nozzle includes a liquid discharge pipe and a seat body fixed at the inlet end of the liquid discharge pipe, the seat body is supported on the upper mounting portion, and the liquid discharge pipe passes through the upper mounting opening and the lower mounting opening in sequence.

[0022] The slurry nozzle comprises a discharge pipe and a seat body, which are independently arranged to flexibly select a rigid seat body and a flexible discharge pipe, so as to realize reliable support of the slurry nozzle and flexible deformation installation of the discharge pipe, and the structure is reliable.

[0023] In a preferred embodiment, the seat body extends in a ring shape along the circumference of the upper mounting opening to cover the gap between the drain pipe and the upper mounting opening;

[0024] In a preferred embodiment, a sealing rib is convexly provided on the outer periphery of the drain pipe, and the sealing rib is located below the lower mounting portion to cover the gap between the drain pipe and the lower mounting opening.

[0025] The seat body can support the entire slurry nozzle, realize the axial limit between the slurry nozzle and the main body seat, and at the same time, can also block the gap between the drain pipe and the upper installation port from above to prevent the steam from flowing further upward. A sealing rib is convexly arranged on the outer periphery of the drain pipe, and the sealing rib is used to block the gap between the drain pipe and the lower installation port from below, thereby preventing the hot steam in the liquid receiving container from flowing upward from the source end, thereby reducing the probability of steam entering the motor installation cavity.

[0026] In a preferred embodiment, the support base and the support cover are locked by a fastener;

[0027] In a preferred embodiment, the main housing includes a shell and a base, the base is supported below the support seat, the shell covers the support cover and the support seat and is provided with a pressing portion pressed tightly on top of the support cover, the shell and the base are locked by fasteners, so that the support seat and the support cover are clamped between the pressing portion and the base.

[0028] Whether fasteners are used to lock the support base and the support cover, or the support base and the support cover are clamped by the housing and the base, reliable fixation between the support base and the support cover can be achieved, so that the motor can be stably mounted in the motor mounting cavity formed by the support base and the support cover, protecting the normal operation of the motor and at the same time providing a certain degree of noise isolation. The fastener locking method makes the assembly simple and firm. The clamping method eliminates the need for fixing parts, simplifies assembly, and provides a reliable structure.

[0029] In a preferred embodiment, the main base further includes a buffer pad covering the upper surface of the support cover.

[0030] By arranging a buffer pad on the upper surface of the support cover, the main frame can form a flexible support for the cup assembly, thereby avoiding collision noise between the cup assembly and the main frame during the operation of the whole machine and reducing the noise of the whole machine.

[0044] like Figure 1-5As shown, the utility model provides a food processing machine with reliable sealing in one embodiment, including a main housing 10, a main base 20 arranged in the main housing 10, and a crushing cup 30 detachably mounted on the main base 20, a valve body 40 is arranged at the bottom of the crushing cup 30, a slurry nozzle 50 is detachably arranged on the main base 20, and the slurry nozzle 50 is detachably connected to the valve body 40, the main base 20 includes a support base 21 and a support cover 22 surrounding a motor installation cavity 201, a motor 23 is installed in the motor installation cavity 201, and a slurry nozzle 50 is detachably connected to the valve body 40. The main base 20 includes a support base 21 and a support cover 22 surrounding a motor installation cavity 201, a motor 23 is installed in the motor installation cavity 201, and a slurry nozzle 50 is arranged in the crushing cup 30. The crushing knife 24 is driven by the motor 23, the support cover 22 is provided with an upper mounting portion 211 which is laterally offset from the motor mounting cavity 201 and an upper mounting opening 212 provided on the upper mounting portion 211, the support seat 21 is provided with a lower mounting portion 221 corresponding to the lower portion of the upper mounting portion 211 and a lower mounting opening 222 provided on the lower mounting portion 221, the pulp nozzle 50 is passed through the upper mounting opening 212 and the lower mounting opening 222, and the main body seat 20 also includes a sealing gasket 25 clamped between the upper mounting portion 211 and the lower mounting portion 221, and the sealing gasket 25 is arranged around the edge of the lower mounting opening.

[0045] It should be noted that the upper installation opening or the lower installation opening can be an annular opening or a notch with an opening; the sealing gasket can be optionally annular surrounding the lower installation opening, or notch-shaped along the edge of the lower installation opening and matching the edge of the lower installation opening.

[0046] Preferably, if Figure 2 As shown, the main base 20 further includes a buffer pad 26 covering the upper surface of the support cover 22, such as a silicone pad.

[0047] Preferably, if Figure 1 , Figure 2 As shown, in this embodiment, the support seat 21 is arched upward to form an installation space for installing the residual water box 61 and the slurry receiving cup 62 on the lower side. When the food processor finishes slurrying, the valve body controls the slurry discharge, and the slurry is discharged into the slurry receiving cup through the slurry nozzle. When the food processor is cleaned, the valve body controls the waste discharge, and the cleaning waste water is discharged into the residual water box 61 through the slurry nozzle. It can be understood that the slurry discharged into the slurry receiving cup is generally hot slurry, which will generate hot steam to flow upward.

[0048] The food processing machine provided by the present invention has a crushing cup 30 detachably mounted above a main base 20, a slurry nozzle 50 is detachably provided on the main base 20, and the slurry nozzle 50 is detachably connected to the valve body 40, so that the user can freely remove the slurry nozzle 50 and remove the crushing cup 30 separately, thereby achieving a thorough cleaning of the slurry nozzle 50. At the same time, the cup body can be removed for pouring out the thick slurry after preparation, avoiding clogging of the slurry nozzle 50. The utility model is reliable to use and can replace different cup bodies to achieve multi-functional expansion. The main base 20 includes a support base 21 and a support cover 22 that enclose a motor installation cavity 201, so as to realize reliable installation and protection of the motor 23. An upper installation portion 211 and an upper installation opening 212 that are laterally staggered from the motor installation cavity 201 are provided on the support cover 22, and the support base 21 is provided with a lower installation portion 221 corresponding to the lower portion of the upper installation portion 211 and a lower installation opening 222 provided on the lower installation portion 221. Therefore, the support base 21 and the support cover 22 integrate the support and limiting functions of the paddle nozzle 50 while realizing the installation function of the motor 23. The upper installation portion 211 and the lower installation portion 221 cooperate to support the paddle nozzle 50, and the upper installation opening 212 and the lower installation opening 222 cooperate to limit the paddle nozzle 50, so as to realize The slurry nozzle 50 can be reliably installed and flexibly disassembled. On this basis, the main base 20 also includes a sealing gasket 25 clamped between the upper mounting portion 211 and the lower mounting portion 221. The sealing gasket 25 is arranged around the edge of the upper mounting port 212. Therefore, the matching gap between the upper mounting portion 211 and the lower mounting portion 221 is reliably sealed. Even if there is a risk of steam entering the matching gap between the slurry nozzle 50 and the mounting port, the sealing gasket 25 can effectively prevent the hot steam generated in the liquid receiving container from further entering the motor mounting cavity 201 laterally, effectively avoiding the increase in temperature and humidity in the motor mounting cavity 201 and causing the insulation of the motor 23 to decrease, thereby protecting the normal operation of the motor 23 and extending the service life of the entire machine. In addition, since the upper mounting portion 211 and the lower mounting portion 221 need to cooperate and have a certain contact in order to support the pulp nozzle 50, a sealing gasket 25 is provided to form a flexible contact between the upper mounting portion 211 and the lower mounting portion 221. When the motor 23 vibrates during operation, the sealing gasket 25 between the upper mounting portion 211 and the lower mounting portion 221 absorbs the transmission of vibration, thereby reducing noise.

[0049] By arranging a buffer pad 26 on the upper surface of the support cover 22, the main base 20 forms a flexible support for the cup assembly, thereby avoiding collision noise between the cup assembly and the main base 20 during the operation of the whole machine and reducing the noise of the whole machine.

[0050] It should be noted that the present invention does not limit the way in which the user installs the paddle nozzle. For example, the user can install the paddle nozzle from top to bottom above the upper mounting portion, and the discharge pipe of the paddle nozzle is sequentially installed in the upper mounting opening and the lower mounting opening from top to bottom; or, the upper part of the paddle nozzle is set to be deformable and flexible, and the paddle nozzle is installed above the upper mounting portion through the lower mounting opening and the upper mounting opening from bottom to top.

[0051] like Figure 3 As shown, in a preferred embodiment, the sealing gasket 25 includes a sealing ring 251 surrounding the upper mounting opening 212 and an extension portion 252 protruding outward from the sealing ring 251, and a limiting structure is provided between the extension portion 252 and the lower mounting portion 221. Figure 4 , 5 As shown, the limiting structure includes a limiting column 71 and a limiting hole 72. The limiting column 71 and the limiting hole 72 are respectively located on the lower mounting portion 221 and the extending portion 252. The limiting column and the limiting hole are plugged in vertically.

[0052] Specifically, combined Figure 3 , 4 As shown, the extension portion 252 protrudes upward to form a limiting hole 72 on the lower side.

[0053] like Figure 5 As shown, the limiting hole 2211 is arranged on the hollow column.

[0054] The sealing gasket 25 includes a sealing ring 251 and an extension 252. The sealing ring 251 is used to surround the upper mounting opening 212 to effectively seal the matching gap between the upper mounting portion 211 and the lower mounting portion 221, and to laterally block the hot steam generated by the docking cup to prevent the steam from entering the motor mounting cavity 201. By setting the extension 252, the extension 252 can form a gripping portion to facilitate the assembly of the sealing gasket 25 by the assembler, and expand the sealing area between the sealing gasket 25 and the lower mounting portion 221 to improve the sealing performance. At the same time, a limiting structure is set between the extension 252 and the lower mounting portion 221, so as to achieve pre-positioning between the sealing gasket 25 and the lower mounting portion 221, which is convenient for rapid installation and subsequent clamping and fixing. In addition, it can avoid the situation where the displacement occurs after the assembly is completed and interferes with the rotation of the paddle nozzle 50 during the user's use of the food processor.

[0055] Of course, it should be noted that, in fact, the limiting structure is not limited to the above-mentioned one. For example, in other embodiments, the positions of the limiting column and the limiting hole are swapped, and the limiting structure includes a limiting column arranged on the extension portion 252 and a limiting hole arranged on the lower mounting portion 221, and the limiting column and the limiting hole are plugged in vertically.

[0056] Alternatively, in other preferred embodiments, the limiting structure includes a stud disposed on one of the extension portion 252 and the lower mounting portion 221 and a screw hole disposed on the other of the extension portion 252 and the lower mounting portion 221, and the screw passes through the screw hole and is locked on the stud; or, in other preferred embodiments, the limiting structure includes a mounting groove disposed on the extension portion 252, and the extension portion 252 is mounted in the mounting groove. Alternatively, the limiting structure includes a plurality of limiting ribs protruding from the extension portion 252, and the limiting ribs are arranged at intervals along the edge of the extension portion 252.

[0057] It can be understood that the limiting structure can select one or more of the above different embodiments.

[0058] For example Figure 5 As shown, in a preferred embodiment, the limiting structure includes not only a limiting column and a limiting hole, but also a plurality of limiting ribs 73 protruding from the extension portion 252 , and two limiting ribs 73 are arranged at intervals along the edge of the extension portion 252 .

[0059] No matter which specific method is adopted by the limiting structure, the pre-installation positioning of the sealing gasket 25 can be effectively realized, and the sealing gasket 25 can be installed quickly and accurately. Specifically, the plug-in method of the limiting column and the limiting hole can provide accurate vertical positioning, ensure that the relative position between the extension part 252 and the lower mounting part 221 is accurate, ensure the installation accuracy and stability, and at the same time, the connection strength is large, improve the stable and reliable installation of the sealing gasket 25, and also play a certain fool-proof effect. The stud and the screw hole are locked with screws, which can provide a reliable fixed connection to ensure that the extension part 252 and the lower mounting part 221 are tightly combined. The extension part 252 is installed in the installation groove, which can achieve accurate positioning and fixing. The installation groove can provide guidance and constraints to ensure that the installation position of the extension part 252 is correct and reduce installation errors. Multiple limiting ribs are arranged at intervals along the edge of the extension part 252, which can limit the position of the extension part 252, prevent it from excessive movement or rotation, and maintain the matching stability of the sealing gasket 25 and the lower mounting part 221 while simplifying the structure.

[0060] like Figure 5 As shown, in a preferred embodiment, the lower mounting portion 221 is provided with an upwardly arched boss 224 , the lower mounting opening 222 is opened on the top surface of the boss 224 , and the boss 224 and the upper mounting portion 211 clamp the sealing gasket 25 .

[0061] By providing the boss 224, the boss 224 is arched upward, which increases the difficulty for water droplets formed after the water vapor condenses to enter the installation opening and the installation gap, thereby further improving the waterproof effect of the main base 20. The boss 224 and the upper mounting portion 211 are used to clamp the sealing gasket 25, which can clamp the sealing gasket 25 more firmly and fix it reliably.

[0062] In a preferred embodiment, Figure 3 , 4 As shown, the sealing gasket 25 is provided with at least one circle of upper annular ribs 253 protruding toward the upper mounting portion 211, and the upper annular ribs 253 abut against the edge of the upper mounting opening 212. More preferably, as Figure 3 As shown, the sealing gasket 25 is provided with two circles of upper annular ribs 253 arranged at intervals, and a sealing groove is formed between the two circles of upper annular ribs 253.

[0063] like Figure 4 As shown, in a preferred embodiment, the sealing gasket 25 is provided with at least one circle of lower annular ribs 254 protruding toward the lower mounting portion 221, and the lower annular ribs 254 abut against the edge of the lower mounting opening 222. More preferably, as Figure 4 As shown, the sealing gasket 25 is provided with two circles of lower annular ribs 254 arranged at intervals, and a sealing groove is formed between the two circles of lower annular ribs 254 .

[0064] Preferably, a sealing ring rib 2211 is protruded on the lower mounting portion 221 to further improve the sealing effect.

[0065] By providing an upper ring rib 253 or a lower ring rib 254 on the sealing gasket 25, and utilizing the upper ring rib 253 to abut against the edge of the upper mounting opening 212, line sealing is achieved compared to directly cooperating between the upper surface of the sealing gasket 25 and the edge of the upper mounting opening 212, thereby extending the path for the lateral flow of steam. Similarly, line sealing is achieved using the lower ring rib 254, thereby greatly reducing the probability of steam entering the interior of the main base 20 and maintaining a dry environment in the motor mounting cavity 201.

[0066] like Figure 2 As shown, in a preferred embodiment, the slurry nozzle 50 includes a discharge pipe 52 and a seat body 51 fixed at the inlet end of the discharge pipe 52, the seat body 51 is supported on the upper mounting portion 211, and the discharge pipe 52 passes through the upper mounting port 212 and the lower mounting port 222 in sequence.

[0067] Preferably, the seat body 51 extends in a ring shape along the circumference of the upper mounting opening 212 to cover the gap between the drain pipe 52 and the upper mounting opening 212;

[0068] As a preference, Figure 2 As shown, a sealing rib 521 is convexly provided on the outer periphery of the drain pipe 52 , and the sealing rib 521 is located below the lower mounting portion 221 to cover the gap between the drain pipe 52 and the lower mounting opening 222 .

[0069] The slurry nozzle 50 includes a drain pipe 52 and a seat body 51, which are independently arranged to flexibly select a rigid seat body 51 and a flexible drain pipe 52, so as to realize reliable support of the slurry nozzle 50 and flexible deformation and installation of the drain pipe 52, and the structure is reliable. The seat body 51 supports the entire slurry nozzle 50, realizes the axial limit between the slurry nozzle 50 and the main body seat 20, and can also block the gap between the drain pipe 52 and the upper mounting port 212 from above to prevent the steam from flowing further upward. A sealing rib 521 is convexly provided on the outer periphery of the drain pipe 52, and the sealing rib 521 is used to block the gap between the drain pipe 52 and the lower mounting port 222 from below, so as to prevent the hot steam in the liquid receiving container from flowing upward from the source end, thereby reducing the probability of steam entering the motor mounting cavity 201.

[0070] It should also be noted that the present invention does not limit the fixing method of the support base 21 and the support cover 22. For example, in a preferred embodiment, the support base 21 and the support cover 22 are locked by fasteners.

[0071] In another preferred embodiment, the main housing 10 includes a shell and a base, the base is supported under the support seat 21, the shell covers the support cover 22 and the support seat 21 and is provided with a holding portion pressed on the top of the support cover 22, the shell and the base are locked by fasteners, so that the support seat 21 and the support cover 22 are clamped between the holding portion and the base.

[0072] Whether fasteners are used to lock the support base 21 and the support cover 22, or the support base 21 and the support cover 22 are clamped by the housing and the base, reliable fixation between the support base 21 and the support cover 22 can be achieved, so that the motor 23 can be stably mounted in the motor installation cavity 201 formed by the support base 21 and the support cover 22, protecting the normal operation of the motor 23 and at the same time blocking noise to a certain extent. The fastener locking method makes the assembly simple and firm. The clamping method eliminates the need for fixing parts, simplifies assembly, and has a reliable structure.
