Description

Technical Field

[0001] The utility model relates to the technical field of garbage processing equipment, in particular to a garbage processor. Background Art

[0002] The garbage disposer uses a motor to drive the pulverizing blade group to pulverize materials. Moreover, during the pulverizing process, it is usually necessary to inject water into the pulverizing chamber. In order to ensure the sealing of the pulverizing chamber, a bushing needs to be installed on the driving motor. The bushing and oil seal are used to seal. Due to the processing accuracy of the bushing, there will be a problem of large interference fit on one side and small interference fit on the other side between the bushing and the oil seal. Long-term wear can easily lead to failure of the seal between the bushing and the oil seal. Utility Model Content

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0004] In view of this, in the first aspect, the utility model proposes a garbage disposer, comprising: a shell, the shell having a mounting hole and a crushing chamber, the mounting hole being connected to the crushing chamber; a driving member, the driving member comprising a driving shaft and a driving body, the driving shaft being connected to the driving body, the driving shaft extending out of a first side of the driving body, and a portion of the driving shaft passing through the mounting hole; a crushing assembly, located in the crushing chamber, the crushing assembly being connected to the driving shaft; a first sealing member, sleeved on the driving shaft, the first sealing member abutting against the first side of the driving body.

[0005] The shell is provided with a delivery port, and kitchen garbage can be put into the crushing chamber through the delivery port. The crushing assembly crushes the kitchen garbage in the crushing chamber. In the process of crushing garbage, in order to improve the crushing effect, it is usually necessary to inject water into the crushing chamber, and the crushed garbage is discharged from the crushing chamber under the drive of the water flow. The shell is provided with a drain port, and the crushed garbage is discharged from the crushing chamber through the drain port under the drive of the water flow. The garbage disposer also includes a valve body, which is used to open or close the drain port, so as to control the discharge timing of the garbage. For example, the valve body can be a solenoid valve.

[0006] A portion of the drive shaft passes through the mounting hole and is connected to the crushing assembly. There is a gap between the drive shaft and the inner wall of the mounting hole. If the liquid in the crushing chamber overflows, the liquid will flow to the surface of the drive body. A first seal is sleeved on the drive shaft, and the first seal abuts against the drive body. Even if liquid overflows, the liquid will not enter the interior of the drive body, thereby improving the sealing of the drive body, ensuring the operating stability of the drive body, and improving the safety of the use of the drive body.

[0007] Exemplarily, the first sealing member is an oil seal or a rubber ring.

[0008] In addition, the garbage disposer in the above technical solution provided by the utility model may also have the following additional technical features:

[0009] In some technical solutions, optionally, a sealing groove is provided on the first side of the driving body, at least a portion of the first sealing member is located in the sealing groove, and the first sealing member is in contact with a groove side wall of the sealing groove.

[0010] The first seal is installed in the sealing groove, and the first seal is in contact with the inner wall of the sealing groove. The first seal ensures that liquid does not easily enter the sealing groove. The sealing groove provides an installation space for the first seal to prevent the first seal from shaking relative to the drive shaft, thereby ensuring the sealing stability of the first seal.

[0011] In a possible application, when the first seal is located in the sealing groove, the first seal is in a deformed state, so that the first seal fits tightly against the inner wall of the sealing groove, which not only ensures that the first seal is not easy to move, but also ensures the sealing effect of the first seal.

[0012] In some technical schemes, optionally, the driving body includes: a top plate and a side plate, the top plate is connected to the side plate, the top plate includes a first part and a second part, the drive shaft extends out of the first part, and the second part extends out of the side of the side plate; a water collecting trough is provided on the first part, and a drain outlet is provided on the second part, the drain outlet is connected to the water collecting trough, and the water collecting trough is distributed around the first sealing member.

[0013] There are multiple side panels, the top panel is located on the top of the multiple side panels, and a portion of the top panel extends out of the side panels, specifically, the first portion does not extend out of the side panels, and the second portion extends out of the side panels.

[0014] A water collecting tank is arranged on the first part. When the liquid in the crushing chamber overflows, the liquid can be collected in the water collecting tank. The water collecting tank is connected to the drain port, and the water in the water collecting tank can be discharged through the drain port. Since the second part extends out of the side of the side plate and the drain port is arranged on the second part, the liquid will not flow along the side plate, thereby preventing the liquid from contacting the main part of the driving member for a long time.

[0015] In some technical solutions, optionally, a connecting groove is provided on the top plate, and the water collecting tank and the drain outlet are connected through the connecting groove.

[0016] When there is a certain gap between the connecting groove and the second part, the water collecting tank and the drain outlet are connected through the connecting groove, so the position of the drain outlet can be set more conveniently. After the position of the drain outlet is selected, the connecting groove is used as a connecting channel to facilitate drainage.

[0017] Of course, in other embodiments, the water collection tank may be directly connected to the drain outlet.

[0018] In some technical solutions, optionally, a boss is provided on the second part, the boss protrudes from the bottom of the second part, and the drain outlet is provided on the boss.

[0019] The boss protrudes from the bottom of the second part, so that the water discharged from the drain port will not flow along the second part to the side plate due to the tension of the water, thereby preventing the liquid from contacting the main part of the driving member for a long time.

[0020] In some technical solutions, optionally, the shell has an installation cavity and a leakage hole, the driving component is located in the installation cavity, and the leakage hole is connected to the installation cavity.

[0021] After the liquid overflowing from the crushing chamber is discharged along the drain port, the liquid will drip to the bottom of the shell. A water leakage hole is provided on the shell, which can discharge the liquid at the bottom of the shell to prevent the liquid from accumulating in the shell for a long time. The water leakage hole can be opened at the bottom of the shell, or at the lower side of the shell.

[0022] In some technical solutions, optionally, the drain port and the water leakage hole are arranged opposite to each other.

[0023] The drain port is directly opposite to the leakage hole, and the liquid dripping from the drain port can enter the leakage hole, so that the liquid can be directly discharged from the shell, thereby preventing the liquid from accumulating at the bottom of the shell.

[0024] In some technical schemes, optionally, the drive shaft includes a positioning section and a driving section, the radial cross-section of the positioning section is a circular cross-section, and the radial cross-section of the driving section and the radial cross-section of the positioning section have different shapes; the garbage disposer also includes: a sleeve, located in the mounting hole, the sleeve includes a first axial hole and a second axial hole, the first axial hole is sleeved on the driving section, the second axial hole is sleeved on the positioning section, the first axial hole is adapted to the shape of the driving section so that the sleeve and the drive shaft rotate synchronously, and the second axial hole is adapted to the shape of the positioning section; a second seal is fixedly connected to the shell and located in the mounting hole, and the second seal is sleeved on the sleeve; wherein the drive shaft has an axis, the distance between any point on the driving section and the axis is L1, the radial length of the positioning section is L2, L1 and L2 satisfy, L1≤L2.

[0025] A portion of the drive shaft passes through the mounting hole and extends into the crushing chamber, and the shaft sleeve is sleeved on the drive shaft, and the shaft sleeve rotates synchronously with the drive shaft. The second seal is installed in the mounting hole, and the second seal fits with the inner wall of the mounting hole. The second seal is sleeved on the shaft sleeve, and the shaft sleeve rotates relative to the second seal. The shaft sleeve and the second seal fit together, thereby ensuring that the liquid in the crushing chamber will not overflow through the mounting hole. A positioning section and a driving section are provided on the shaft sleeve drive shaft, wherein the radial cross section of the positioning section is circular, and the radial cross section of the driving section is different from the radial cross section of the positioning section. Therefore, the radial cross section of the driving section is not circular, but other shapes except for a circle, for example, the radial cross section of the driving section is a polygon. The shaft sleeve is provided with a first shaft hole and a second shaft hole, wherein the shape of the first shaft hole is adapted to the driving section, that is, the first shaft hole is a non-circular hole, and the shape of the second shaft hole is adapted to the positioning section, so the shape of the second shaft hole is a circular hole.

[0026] When the shaft sleeve and the driving shaft are assembled, the first shaft hole is sleeved on the driving section, and the second shaft hole is sleeved on the positioning section. Since the cross section of the positioning section is circular, the circular positioning section has better processing properties, ensuring that the positioning section has a higher processing accuracy. When the second shaft hole and the positioning section are sleeved on each other, the second shaft hole can be accurately matched with the positioning section, thereby ensuring the positioning accuracy of the shaft sleeve and improving the concentricity of the shaft sleeve and the driving shaft.

[0027] Since the cross section of the driving section is non-circular, when the first shaft hole and the driving section are sleeved with each other, the sleeve cannot generate relative movement with the driving section, thereby ensuring that the driving shaft can drive the sleeve to rotate synchronously.

[0028] The shaft hole of the sleeve is divided into two sections, the first section cooperates with the circular cross-section positioning section, and the second section cooperates with the non-circular cross-section driving section, so that the concentricity of the sleeve can be guaranteed, and the sleeve can be synchronously rotated with the driving shaft. Since the concentricity of the sleeve and the driving shaft is improved, when the sleeve rotates relative to the second sealing member, the interference between the sleeve and the second sealing member at various locations in the circumferential direction is basically the same, the sleeve and the second sealing member are effectively sealed, and the sleeve and the second sealing member are not prone to sealing failure, which prevents the liquid in the crushing chamber from overflowing and affecting the stable operation of the electrical device.

[0029] The distance between any point on the driving section and the axis is smaller than the radius of the positioning section, so that the positioning function of the sleeve is realized by the positioning section. The positioning section has high processing accuracy, thereby ensuring the concentricity of the sleeve and the driving shaft.

[0030] In some technical solutions, optionally, the radial cross-section of the driving segment is a polygon; or at least a portion of the outer circumference of the radial cross-section of the driving segment is a straight line; or the radial cross-section of the driving segment is irregularly shaped.

[0031] The radial cross section of the driving section can be polygonal, so the first axial hole is a polygonal hole. When the first axial hole is sleeved on the driving section, the sleeve is difficult to rotate relative to the driving section, thereby ensuring that the sleeve rotates synchronously with the driving shaft.

[0032] In the radial cross-section of the driving segment, at least one side is a straight line, and the other sides can be straight lines or arcs. When the driving segment and the first shaft hole structure are adapted, as long as one side in the radial cross-section of the driving segment is a straight line, the sleeve will not rotate relative to the driving segment. Therefore, the flat-mouth structure can be directly processed at one end of the positioning segment, that is, the driving segment can be obtained by cutting one end of the positioning segment. In this way, the difficulty of processing the driving segment can be reduced.

[0033] The radial cross-section of the driving section may be of a special shape. For example, the radial cross-section of the driving section may be composed of multiple arcs, such as a petal shape, or the radial cross-section of the driving section may be composed of a straight line plus an arc, or the radial cross-section of the driving section may also be other irregular shapes.

[0034] In some technical solutions, optionally, the axial length of the driving section is H, and H satisfies, H≥1mm.

[0035] When the drive shaft drives the sleeve to rotate, the drive section can drive the sleeve to rotate, and the axial length of the drive section is limited to be greater than or equal to 1 mm. Therefore, the axial matching length of the drive section and the sleeve can be greater than or equal to 1 mm. Within this range, the drive section and the sleeve can be in stably contact, and the sleeve is not likely to produce relative movement with the drive section, thereby ensuring that the drive section can stably drive the sleeve to rotate.

[0036] Moreover, when the drive shaft rotates, the drive section will exert a force on the sleeve, and the drive section will also be subjected to the reaction force of the sleeve. The length of the drive section is limited to be greater than or equal to 1 mm, the force-bearing surface on the drive section is larger, the structure of the drive section is not easily damaged, and the damage rate of the drive section is reduced.

[0037] In some technical solutions, optionally, the first end of the positioning segment is close to the crushing assembly, and the driving segment is located at the first end of the positioning segment.

[0038] The driving section is arranged at one end of the positioning section, so the end of the driving shaft can be processed to form the driving section at the end of the driving shaft. The method of processing the driving section at the end of the driving shaft can improve the processing convenience of the driving section.

[0039] The driving section is a structure obtained by processing a part of the driving shaft. The distance between at least a part of the edge of the driving section and the axis is smaller than the radius of the positioning section. Therefore, the structural strength of the driving section is smaller than the structural strength of the positioning section. If the driving section is set in the middle section of the positioning section, when the driving shaft is subjected to force, bending, deformation or fracture may occur in the middle section of the positioning section. In order to ensure the structural stability of the driving shaft, the driving section is set at the axial end of the positioning section to ensure that the driving shaft can stably drive the crushing assembly to rotate.

[0040] In some technical solutions, optionally, the sleeve includes: a first mating segment and a second mating segment, the first mating segment is connected to the second mating segment, the first mating segment is provided with a first axial hole, the second mating segment is provided with a second axial hole, and the radial thickness of at least a portion of the first mating segment is greater than the radial thickness of the second mating segment.

[0041] The first matching section is sleeved on the driving section, and the second matching section is sleeved on the positioning section. The distance between at least a portion of the edge of the driving section and the axis is smaller than the radius of the positioning section, so the radial dimension of at least a portion of the driving section is smaller than the radial dimension of the positioning section. The radial thickness of at least a portion of the first matching section is set to be greater than the radial thickness of the second matching section, so that the structure of the first matching section is adapted to the driving section, and the structure of the second matching section is adapted to the positioning section, thereby ensuring stable matching between the sleeve and the driving shaft.

[0042] In some technical solutions, optionally, the driving section is arranged on the first end face of the positioning section, and one axial end of the first matching section abuts against the first end face.

[0043] Since the radial length of at least a part of the driving section is smaller than the radial length of the positioning section, the positioning portion extends out of the side of the driving section, and the driving section is installed on the first end surface, so that the driving section does not cover the entire first end surface. When the sleeve is installed on the driving shaft, the end of the driving section can abut against the first end surface, and the first end surface acts as a limit on the driving section to prevent the sleeve from moving relative to the driving shaft.

[0044] In some technical solutions, optionally, a connecting hole is provided on the driving shaft, and the connecting hole extends from the driving section to the positioning section; the crushing assembly includes: a crushing piece, which is located in the crushing chamber; and a connecting piece, which extends into the connecting hole, and the connecting piece is used to connect the crushing piece to the driving shaft.

[0045] A connecting hole is formed on the driving shaft, and the connecting hole extends along the axial direction of the driving shaft. A part of the connecting piece can be assembled into the connecting hole, and the connecting piece can lock the crushing piece on the driving shaft, so that the driving shaft can drive the crushing piece to rotate, and the crushing piece crushes the material when rotating.

[0046] Since at least a portion of the radial dimension of the driving section is smaller than the radial dimension of the positioning section, at least a portion of the driving section is thinner, while the positioning section is relatively thicker. When the crushing piece rotates, the inner wall of the connecting hole will be subjected to the force of the connecting piece. If the connecting hole is only provided on the driving section, the driving section will be subjected to the direct force of the connecting piece, and since a portion of the driving section is relatively thin, there may be risks of deformation and bending of the driving section. A portion of the connecting hole is extended to the positioning section. Since the positioning section is relatively thick and has a relatively high structural strength, the positioning section is not prone to deformation, bending, and other problems when subjected to the force of the connecting piece, thereby ensuring that the driving shaft can stably drive the crushing piece to rotate.

[0047] In some technical solutions, optionally, the crushing piece is sleeved on the driving section, and a part of the crushing piece is located between the connecting piece and the shaft sleeve.

[0048] After the crushing piece is sleeved on the driving section, the connecting piece is installed in the connecting hole, and the end of the connecting piece presses the crushing piece against the shaft sleeve, so that the crushing piece is not easy to rotate relative to the driving section, thereby ensuring that the driving section and the crushing piece can rotate synchronously. By clamping the crushing piece by the connecting piece and the shaft sleeve, there is no need to set a structure for limiting the crushing piece on the driving shaft, which is conducive to simplifying the processing process of the driving shaft.

[0049] In some technical solutions, optionally, a plurality of recessed portions are provided on the outer ring of the sleeve, the recessed portions are used to store oil, and the second sealing member covers the recessed portions.

[0050] When the drive shaft rotates, the drive shaft drives the sleeve to rotate, and the sleeve rotates relative to the second seal, and the sleeve and the second seal rub against each other. A recessed portion is provided on the outer ring of the sleeve, and the recessed portion can store oil, and the oil can reduce the friction between the sleeve and the second seal, reduce the damage speed of the sleeve, and ensure that the sleeve can stably cooperate with the second seal to seal.

[0051] In some technical solutions, optionally, along the axial direction of the drive shaft, the length of the sleeve is greater than the length of the second seal.

[0052] Since the axial length of the sleeve is greater than the axial length of the second seal, the second seal fits the sleeve as a whole along the axial direction of the second seal, maximizing the contact area between the second seal and the sleeve, which is beneficial to improving the sealing effect between the second seal and the sleeve.

DETAILED DESCRIPTION

[0070] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0071] In the following description, many specific details are set forth to facilitate 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 protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0072] Refer to the following Figures 1 to 13 A garbage disposer provided according to some embodiments of the present invention is described.

[0073] Combination Figure 1 , Figure 2 and Figure 5 As shown, the utility model proposes a garbage disposer, including: a housing 100, a driving member 200, a crushing assembly 300 and a first sealing member 510, wherein the housing 100 has a mounting hole 110 and a crushing chamber 120, and the mounting hole 110 is connected to the crushing chamber 120. The driving member includes a driving shaft 210 and a driving body 220, wherein the driving shaft 210 is connected to the driving body 220, the driving shaft 210 extends out of a first side of the driving body 220, and a portion of the driving shaft 210 passes through the mounting hole 110. The crushing assembly 300 is located in the crushing chamber 120, and the crushing assembly 300 is connected to the driving shaft 210. The first sealing member 510 is sleeved on the driving shaft 210, and the first sealing member 510 abuts against a first side of the driving body 220.

[0074] The housing 100 is provided with a delivery port 131, and kitchen garbage can be delivered into the crushing chamber 120 through the delivery port 131. The crushing assembly 300 crushes the kitchen garbage in the crushing chamber 120. In the process of crushing garbage, in order to improve the crushing effect, it is usually necessary to inject water into the crushing chamber 120, and the crushed garbage is discharged from the crushing chamber 120 under the drive of the water flow. The housing 100 is provided with a drain port, and the crushed garbage is discharged from the crushing chamber 120 through the drain port under the drive of the water flow. The garbage disposer also includes a valve body, which is used to open or close the drain port, so as to control the discharge timing of the garbage. For example, the valve body can be a solenoid valve.

[0075] A portion of the drive shaft 210 passes through the mounting hole 110 and is connected to the crushing assembly 300. There is a gap between the drive shaft 210 and the inner wall of the mounting hole 110. If the liquid in the crushing chamber 120 overflows, the liquid will flow to the surface of the drive body 220. A first seal 510 is sleeved on the drive shaft 210, and the first seal 510 abuts against the drive body 220. Even if liquid overflows, the liquid will not enter the inside of the drive body 220, thereby improving the sealing performance of the drive body 220, ensuring the operating stability of the drive body 220, and improving the safety of the use of the drive body 220.

[0076] Exemplarily, the first sealing member 510 is an oil seal or a rubber ring.

[0077] In some embodiments, optionally, a sealing groove 221 is provided on the first side of the driving body 220 , at least a portion of the first sealing member 510 is located in the sealing groove 221 , and the first sealing member 510 is in contact with a groove side wall of the sealing groove 221 .

[0078] The first seal 510 is installed in the sealing groove 221, and the first seal 510 fits against the inner wall of the sealing groove 221. The first seal 510 ensures that liquid does not easily enter the interior of the sealing groove 221. The sealing groove 221 provides an installation space for the first seal 510 to prevent the first seal 510 from shaking relative to the drive shaft 210, thereby ensuring the sealing stability of the first seal 510.

[0079] In a possible application, the sealing groove 221 is concentric with the driving shaft 210 .

[0080] In a possible application, when the first seal 510 is located in the sealing groove 221, the first seal 510 is in a deformed state, so that the first seal 510 fits tightly against the inner wall of the sealing groove 221, thereby ensuring that the first seal 510 is not easy to move and the sealing effect of the first seal 510 is ensured.

[0081] Combination Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, optionally, the driving body 220 includes: a top plate 222 and a side plate 223, the top plate 222 is connected to the side plate 223, the top plate 222 includes a first portion 224 and a second portion 225, the driving shaft 210 extends out of the first portion 224, and the second portion 225 extends out of the side of the side plate 223. A water collecting trough 226 is provided on the first portion 224, and a drain port 227 is provided on the second portion 225, the drain port 227 is connected to the water collecting trough 226, and the water collecting trough 226 is distributed around the first sealing member 510.

[0082] There are multiple side panels 223 , the top panel 222 is located at the top of the multiple side panels 223 , and a portion of the top panel 222 extends out of the side of the side panel 223 , specifically, the first portion 224 does not extend out of the side of the side panel 223 , and the second portion 225 extends out of the side of the side panel 223 .

[0083] A water collecting trough 226 is provided on the first part 224. When the liquid in the pulverizing chamber 120 overflows, the liquid can be collected in the water collecting trough 226. The water collecting trough 226 is connected to the drain port 227, and the water in the water collecting trough 226 can be discharged through the drain port 227. Since the second part 225 extends out of the side of the side plate 223 and the drain port 227 is provided on the second part 225, the liquid will not flow along the side plate 223, thereby preventing the liquid from contacting the main part of the driving member for a long time.

[0084] like Figure 3 As shown, in some embodiments, optionally, a connecting groove 228 is provided on the top plate 222 , and the water collecting groove 226 and the drain outlet 227 are connected through the connecting groove 228 .

[0085] When there is a certain gap between the connecting groove 228 and the second part 225, the water collecting tank 226 and the drain outlet 227 are connected through the connecting groove 228, so the position of the drain outlet 227 can be set more conveniently. After the position of the drain outlet 227 is selected, the connecting groove 228 is used as a connecting channel to facilitate drainage.

[0086] Of course, in other embodiments, the water collection tank 226 and the drain outlet 227 may also be directly connected.

[0087] like Figure 2 As shown, in some embodiments, optionally, a boss 229 is provided on the second portion 225 , the boss 229 protrudes from the bottom of the second portion 225 , and the drain port 227 is provided on the boss 229 .

[0088] The boss 229 protrudes from the bottom of the second portion 225 so that the water discharged from the drain port 227 will not flow along the second portion 225 to the side plate 223 due to the tension of the water, thereby preventing the liquid from contacting the main body of the driving member for a long time.

[0089] Combination Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, optionally, the housing 100 has an installation cavity 150 and a water leakage hole 160 , the driving member is located in the installation cavity 150 , and the water leakage hole 160 is communicated with the installation cavity 150 .

[0090] After the liquid overflowing from the pulverizing chamber 120 is discharged along the drain port 227, the liquid will drip to the bottom of the housing 100. The housing 100 is provided with a water leakage hole 160, which can discharge the liquid at the bottom of the housing 100 to prevent the liquid from accumulating in the housing 100 for a long time. The water leakage hole 160 can be provided at the bottom of the housing 100, or at a lower position of the side of the housing 100.

[0091] In some embodiments, optionally, the drain port 227 and the water leakage hole 160 are arranged opposite to each other.

[0092] The drain port 227 is directly opposite to the water leakage hole 160 , and the liquid dripping from the drain port 227 can enter the water leakage hole 160 , so that the liquid can be directly discharged from the shell 100 , thereby preventing the liquid from accumulating at the bottom of the shell 100 .

[0093] Combination Figure 1 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, in some embodiments, optionally, the drive shaft 210 includes a positioning section 211 and a driving section 212, the radial cross section of the positioning section 211 is a circular cross section, and the radial cross section of the driving section 212 is different from the radial cross section of the positioning section 211. The garbage disposer also includes: a sleeve 400 and a second seal 520, the sleeve 400 is located in the mounting hole 110, the sleeve 400 includes a first shaft hole 410 and a second shaft hole 420, the first shaft hole 410 is sleeved on the driving section 212, the second shaft hole 420 is sleeved on the positioning section 211, the first shaft hole 410 is adapted to the shape of the driving section 212, so that the sleeve 400 and the drive shaft 210 rotate synchronously, and the second shaft hole 420 is adapted to the shape of the positioning section 211. The second seal 520 is fixedly connected to the housing 100, and the second seal 520 is located in the mounting hole 110, and the second seal 520 is sleeved on the sleeve 400. The driving shaft 210 has an axis, the distance between any point on the driving section 212 and the axis is L1, the radial length of the positioning section 211 is L2, and L1 and L2 satisfy that L1≤L2.

[0094] The housing 100 is provided with a delivery port 131, and kitchen garbage can be delivered into the crushing chamber 120 through the delivery port 131. The crushing assembly 300 crushes the kitchen garbage in the crushing chamber 120. In the process of crushing garbage, in order to improve the crushing effect, it is usually necessary to inject water into the crushing chamber 120, and the crushed garbage is discharged from the crushing chamber 120 under the drive of the water flow. The housing 100 is provided with a drain port, and the crushed garbage is discharged from the crushing chamber 120 through the drain port under the drive of the water flow. The garbage disposer also includes a valve body, which is used to open or close the drain port, so as to control the discharge timing of the garbage. For example, the valve body can be a solenoid valve.

[0095] A portion of the drive shaft 210 passes through the mounting hole 110 and extends into the pulverizing chamber 120. The shaft sleeve 400 is sleeved on the drive shaft 210, and the shaft sleeve 400 rotates synchronously with the drive shaft 210. The second seal 520 is installed in the mounting hole 110, and the second seal 520 fits with the inner wall of the mounting hole 110. The second seal 520 is sleeved on the shaft sleeve 400, and the shaft sleeve 400 rotates relative to the second seal 520. The shaft sleeve 400 and the second seal 520 fit each other, thereby ensuring that the liquid in the pulverizing chamber 120 will not overflow through the mounting hole 110. The shaft sleeve 400 drive shaft 210 is provided with a positioning section 211 and a driving section 212, wherein the radial cross section of the positioning section 211 is circular, and the radial cross section of the driving section 212 is different from the radial cross section of the positioning section 211. Therefore, the radial cross section of the driving section 212 is not circular, but other shapes other than circular, for example, the radial cross section of the driving section 212 is polygonal. The shaft sleeve 400 is provided with a first shaft hole 410 and a second shaft hole 420, wherein the shape of the first shaft hole 410 is adapted to the driving section 212, that is, the first shaft hole 410 is a non-circular hole, and the shape of the second shaft hole 420 is adapted to the positioning section 211, so the shape of the second shaft hole 420 is a circular hole.

[0096] When the sleeve 400 and the drive shaft 210 are assembled, the first shaft hole 410 is sleeved on the drive section 212, and the second shaft hole 420 is sleeved on the positioning section 211. Since the cross section of the positioning section 211 is circular, the circular positioning section 211 has better processing properties, ensuring that the positioning section 211 has a higher processing accuracy. When the second shaft hole 420 and the positioning section 211 are sleeved on each other, the second shaft hole 420 can be accurately matched with the positioning section 211, thereby ensuring the positioning accuracy of the sleeve 400 and improving the concentricity of the sleeve 400 and the drive shaft 210.

[0097] Since the cross section of the driving section 212 is non-circular, when the first shaft hole 410 and the driving section 212 are mutually sleeved, the sleeve 400 cannot generate relative movement with the driving section 212, thereby ensuring that the driving shaft 210 can drive the sleeve 400 to rotate synchronously.

[0098] The shaft hole of the sleeve 400 is divided into two sections, the first section cooperates with the circular cross-section positioning section 211, and the second section cooperates with the non-circular cross-section driving section 212, so that the concentricity of the sleeve 400 can be ensured, and the sleeve 400 can be ensured to rotate synchronously with the driving shaft 210. Since the concentricity of the sleeve 400 and the driving shaft 210 is improved, when the sleeve 400 rotates relative to the second sealing member 520, the interference between the sleeve 400 and the second sealing member 520 at various locations in the circumferential direction is basically the same, the sleeve 400 and the second sealing member 520 are effectively sealed, and the sleeve 400 and the second sealing member 520 are not prone to sealing failure, so as to avoid the overflow of liquid in the crushing chamber 120 and affect the stable operation of the electrical device.

[0099] In a possible application, the driving section 212 and the positioning section 211 are an integrated structure.

[0100] The distance between any point on the driving section 212 and the axis is smaller than the radius of the positioning section 211, so that the positioning function of the sleeve 400 is achieved by the positioning section 211. The positioning section 211 has high processing accuracy, thereby ensuring the concentricity of the sleeve 400 and the driving shaft 210.

[0101] In the embodiment of the present invention, even if the second sealing member 520 fails, the first sealing member 510 can still waterproof the driving member 200 to avoid affecting the use of the driving member 200.

[0102] In a possible application, the driving member 200 includes a motor, which is connected to the crushing assembly 300 , or the driving member 200 includes a motor and a reducer, which is connected to the reducer, and the reducer is connected to the crushing assembly 300 .

[0103] In some embodiments, optionally, the radial cross-section of the driving segment 212 is a polygon; or at least a portion of the outer circumference of the radial cross-section of the driving segment 212 is a straight line; or the radial cross-section of the driving segment 212 is irregularly shaped.

[0104] like Fig.11 As shown, the radial cross-section of the driving section 212 can be a polygon, and therefore, the first axial hole 410 is a polygonal hole. When the first axial hole 410 is sleeved on the driving section 212, the sleeve 400 is difficult to rotate relative to the driving section 212, thereby ensuring that the sleeve 400 rotates synchronously with the driving shaft 210.

[0105] like Fig.12As shown, in the radial cross-section of the driving segment 212, at least one side is a straight line, and the other sides can be straight lines or arcs. When the driving segment 212 and the first axial hole 410 are structurally adapted, in the radial cross-section of the driving segment 212, as long as there is one side that is a straight line, the sleeve 400 will not rotate relative to the driving segment 212. Therefore, the flat-mouth structure can be directly processed at one end of the positioning segment 211, that is, the driving segment 212 can be obtained by cutting one end of the positioning segment 211. In this way, the difficulty of processing the driving segment 212 can be reduced.

[0106] like Fig.13 As shown, the radial cross-section of the driving section 212 can be irregular, for example, the radial cross-section of the driving section 212 can be composed of multiple arcs, such as a petal shape, or the radial cross-section of the driving section 212 can be composed of a straight line plus an arc, or the radial cross-section of the driving section 212 can also be other irregular shapes.

[0107] like Figure 6 As shown, in some embodiments, optionally, the axial length of the driving section 212 is H, and H satisfies, H≥1 mm.

[0108] When the drive shaft 210 drives the sleeve 400 to rotate, the drive section 212 can drive the sleeve 400 to rotate, and the axial length of the drive section 212 is limited to be greater than or equal to 1 mm. Therefore, the axial matching length of the drive section 212 and the sleeve 400 can be greater than or equal to 1 mm. Within this range, the drive section 212 and the sleeve 400 can be in stably contact with each other, and the sleeve 400 is not easy to produce relative movement with the drive section 212, thereby ensuring that the drive section 212 can stably drive the sleeve 400 to rotate.

[0109] Moreover, when the driving shaft 210 rotates, the driving section 212 will exert a force on the sleeve 400, and the driving section 212 will also be subjected to the reaction force of the sleeve 400, which limits the length of the driving section 212 to be greater than or equal to 1 mm. The force-bearing surface on the driving section 212 is larger, and the structure of the driving section 212 is not easily damaged, thereby reducing the damage rate of the driving section 212.

[0110] Combination Figure 1 and Figure 6 As shown, in some embodiments, optionally, the first end of the positioning segment 211 is close to the pulverizing assembly 300 , and the driving segment 212 is located at the first end of the positioning segment 211 .

[0111] The driving section 212 is arranged at one end of the positioning section 211. Therefore, the end of the driving shaft 210 can be processed to form the driving section 212 at the end of the driving shaft 210. The method of processing the driving section 212 at the end of the driving shaft 210 can improve the processing convenience of the driving section 212.

[0112] The driving section 212 is a structure obtained by processing a part of the driving shaft 210. The distance between at least a part of the edge of the driving section 212 and the axis is smaller than the radius of the positioning section 211. Therefore, the structural strength of the driving section 212 is smaller than the structural strength of the positioning section 211. If the driving section 212 is set in the middle section of the positioning section 211, when the driving shaft 210 is subjected to force, bending, deformation or fracture may occur in the middle section of the positioning section 211. In order to ensure the structural stability of the driving shaft 210, the driving section 212 is set at the axial end of the positioning section 211 to ensure that the driving shaft 210 can stably drive the crushing assembly 300 to rotate.

[0113] Combination Figure 5 , Figure 7 , Fig. 9 and Fig.10 As shown, in some embodiments, optionally, the sleeve 400 includes: a first mating segment 430 and a second mating segment 440, the first mating segment 430 is connected to the second mating segment 440, the first mating segment 430 is provided with a first axial hole 410, the second mating segment 440 is provided with a second axial hole 420, and the radial thickness of at least a portion of the first mating segment 430 is greater than the radial thickness of the second mating segment 440.

[0114] The first matching section 430 is sleeved on the driving section 212, and the second matching section 440 is sleeved on the positioning section 211. The distance between the edge of at least a portion of the driving section 212 and the axis is smaller than the radius of the positioning section 211. Therefore, the radial dimension of at least a portion of the driving section 212 is smaller than the radial dimension of the positioning section 211. The radial thickness of at least a portion of the first matching section 430 is set to be greater than the radial thickness of the second matching section 440, so that the structure of the first matching section 430 is adapted to the driving section 212, and the structure of the second matching section 440 is adapted to the positioning section 211, thereby ensuring the stable matching of the sleeve 400 and the driving shaft 210.

[0115] like Figure 7 As shown, in some embodiments, optionally, the driving section 212 is disposed on the first end surface 213 in the positioning section 211 , and one axial end of the first matching section 430 abuts against the first end surface 213 .

[0116] Since the radial length of at least a part of the driving section 212 is smaller than the radial length of the positioning section 211, the positioning section extends out of the side of the driving section 212, and the driving section 212 is installed on the first end surface 213, so that the driving section 212 does not cover the entire first end surface 213. When the sleeve 400 is installed on the driving shaft 210, the end of the driving section 212 can be against the first end surface 213, and the first end surface 213 has a limiting effect on the driving section 212, so as to prevent the sleeve 400 from moving relative to the driving shaft 210.

[0117] In some embodiments, optionally, a connecting hole 214 is provided on the driving shaft 210, and the connecting hole 214 extends from the driving section 212 to the positioning section 211. The crushing assembly 300 includes: a crushing piece 310 and a connecting piece 320. The crushing piece 310 is located in the crushing chamber 120, and the connecting piece 320 extends into the connecting hole 214. The connecting piece 320 is used to connect the crushing piece 310 to the driving shaft 210.

[0118] A connecting hole 214 is formed on the driving shaft 210, and the connecting hole 214 extends along the axial direction of the driving shaft 210. A part of the connecting member 320 can be assembled into the connecting hole 214, and the connecting member 320 can lock the crushing member 310 on the driving shaft 210, so that the driving shaft 210 can drive the crushing member 310 to rotate, and the crushing member 310 crushes the material when rotating.

[0119] Since at least a portion of the radial dimension of the driving section 212 is smaller than the radial dimension of the positioning section 211, at least a portion of the driving section 212 is thinner, while the positioning section 211 is relatively thicker. When the crushing element 310 rotates, the inner wall of the connecting hole 214 will be subjected to the force of the connecting member 320. If the connecting hole 214 is only provided on the driving section 212, the driving section 212 will be subjected to the direct force of the connecting member 320, and since a portion of the driving section 212 is relatively thin, there may be risks of deformation and bending of the driving section 212. A portion of the connecting hole 214 is extended to the positioning section 211. Since the positioning section 211 is relatively thick and has a relatively high structural strength, when subjected to the force of the connecting member 320, the positioning section 211 is not prone to deformation, bending, and other problems, thereby ensuring that the driving shaft 210 can stably drive the crushing element 310 to rotate.

[0120] Exemplarily, the connecting member 320 is a screw, and the connecting hole 214 is a threaded hole.

[0121] In a possible application, the shredder 310 includes a cutter shaft and a blade, the blade is disposed on the cutter shaft, and the cutter shaft sleeve 400 is disposed on the driving shaft 210 .

[0122] like Figure 5 As shown, in some embodiments, optionally, the pulverizing member 310 is sleeved on the driving section 212 , and a portion of the pulverizing member 310 is located between the connecting member 320 and the sleeve 400 .

[0123] After the crushing piece 310 is sleeved on the driving section 212, the connecting piece 320 is installed in the connecting hole 214, and the end of the connecting piece 320 presses the crushing piece 310 against the shaft sleeve 400, so that the crushing piece 310 is not easy to rotate relative to the driving section 212, thereby ensuring that the driving section 212 and the crushing piece 310 can rotate synchronously. By clamping the crushing piece 310 by the connecting piece 320 and the shaft sleeve 400, there is no need to set a structure for limiting the crushing piece 310 on the driving shaft 210, which is conducive to simplifying the processing process of the driving shaft 210.

[0124] In some embodiments, optionally, a plurality of recessed portions (not shown in the figure) are provided on the outer ring of the sleeve 400, the recessed portions are used to store oil, and the second sealing member 520 covers the recessed portions.

[0125] When the drive shaft 210 rotates, the drive shaft 210 drives the sleeve 400 to rotate, and the sleeve 400 rotates relative to the second seal 520, and the sleeve 400 and the second seal 520 rub against each other. A recessed portion is provided on the outer ring of the sleeve 400, and the recessed portion can play the role of storing oil. The oil can reduce the friction between the sleeve 400 and the second seal 520, reduce the damage speed of the sleeve 400, and ensure that the sleeve 400 can stably cooperate with the second seal 520 for sealing.

[0126] In a possible application, the sleeve 400 is made by using a powder metallurgy process, so that the outer surface of the sleeve 400 forms an uneven structure (depression).

[0127] Combination Figure 5 and Figure 7 As shown, in some embodiments, optionally, along the axial direction of the drive shaft 210 , the length of the sleeve 400 is greater than the length of the second seal 520 .

[0128] Since the axial length of the sleeve 400 is greater than the axial length of the second seal 520, the second seal 520 fits the sleeve 400 as a whole along the axial direction of the second seal 520, maximizing the contact area between the second seal 520 and the sleeve 400, which is beneficial to improving the sealing effect between the second seal 520 and the sleeve 400.

[0129] like Figure 1 As shown, in some embodiments, optionally, the shell 100 includes an outer shell 140 and a crushing body 130, the crushing body 130 is connected to the outer shell 140, and the crushing body 130 is located in the outer shell 140, for example, the crushing body 130 is locked on the outer shell 140 by screws, or the crushing body 130 and the outer shell 140 are integrally formed, the crushing body 130 has a feeding port 131, a crushing chamber 120 and a drain port, and the space between the crushing body 130 and the outer shell 140 is used to install a driving member 200 and other electrical components.

[0130] In a possible application, the garbage disposer further includes: a flange 900 , the flange 900 is connected to the housing 100 , and the garbage disposer is installed at the bottom of the sink through the flange 900 .

[0131] The garbage disposer also includes a splash plug 600 and a push plug 700. The splash plug 600 is installed on the crushing body 130. The splash plug 600 is made of rubber or polytetrafluoroethylene. An opening is set in the center of the splash plug 600. The aperture of the opening is small. When the garbage is crushed, the splash plug 600 blocks the material to prevent the material from splashing out. When it is necessary to put garbage into the crushing body 130, it is necessary to push the splash plug 600 so that the splash plug 600 is deformed and the aperture of the opening is increased.

[0132] The push plug 700 is slidably connected to the crushing body 130 . The push plug 700 may be a columnar structure. The push plug 700 may pass through the opening on the anti-splash plug 600 , so that the thrown garbage may be pushed into the crushing chamber 120 .

[0133] In a possible application, the garbage disposer further includes a drain pipe 800 , which is connected to the crushing body 130 . Specifically, the drain pipe 800 is connected to a drain port on the crushing body 130 , and the crushed liquid can be discharged through the drain pipe 800 .

[0134] In the present invention, the term "plurality" means two or more than two, unless otherwise clearly defined. The terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "connected" can be a direct connection or an indirect connection through an intermediate medium.
