[0032] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific applications. For example, although the specification describes the guide portion including a balance ring guide, and the balance ring guide and the balance ring are integrally formed as an example, the present invention can obviously adopt other similar means, such as the balance ring guide and the inner wall are integrally formed, etc., as long as when the shoe moves between the impeller and the balance ring and the two ends of the shoe are respectively in contact with the impeller and the balance ring, the guidance of the guide portion causes the shoe to slide to a position where it is not subjected to the extrusion force applied by the balance ring.

[0033] It should be noted that, in the description of the present invention, terms such as "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0034] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connection", "setting", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, etc. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] To solve the problem that when washing shoes whose length exceeds the height of the washing bucket in a shoe washing machine with a shallow depth, the washed shoes are easily stuck between the impeller and the balance ring, which not only affects the washing effect but also causes damage to the shoes. Figure 1-2 As shown, the present invention provides a shoe washing device, which includes a washing tub 1, a driving member arranged outside the washing tub 1 (not shown in the figure, the driving member in this embodiment may be a motor), a impeller 2 arranged inside the washing tub 1, and a balancing ring 3 fixedly arranged on the top of the washing tub 1; the output end of the driving member is transmission-connected to the impeller 2 for driving the impeller 2 to rotate. The shoe washing device also includes a guide portion, which is arranged inside the washing tub 1, and the guide portion is used to guide the shoes to slide to a position where they are not subjected to the squeezing force applied by the balancing ring 3. The guide portion includes a balancing ring guide 4, which is arranged at the bottom of the balancing ring 3, and the inner diameter of the guide portion gradually increases from top to bottom. Specifically, the inner side surface of the guide portion may be an inclined surface, and the guide portion and the balancing ring 3 are integrally formed.

[0036] In summary, when the shoe washing device of the present invention washes shoes, when the shoes move between the impeller 2 and the balance ring 3 and the two ends of the shoes abut against the impeller 2 and the balance ring 3 respectively (specifically, in this embodiment, the shoes abut against the balance ring 3 indirectly by directly abutting against the guide part), the present invention can guide the shoes through the guide part so that the shoes slide to a position where they are not subjected to the squeezing force of the balance ring 3. Even when the shoe washing device of the present invention washes shoes whose length exceeds the height of the washing tub 1, it is not easy for the shoes to get stuck between the impeller 2 and the balance ring 3, and it will not hinder the flipping of the shoes, nor reduce the washing effect due to the stuck shoes, nor cause the shoes to be continuously impacted by the balance ring 3 and the impeller 2 and cause damage.

[0037] It should be noted that the above embodiments are only used to illustrate the principles of the present invention and are not used to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structures through other replaceable implementations so that the present invention can be applied to more specific application scenarios. These do not deviate from the principles of the present invention and therefore will fall within the scope of protection of the present invention.

[0038] For example, in an alternative implementation, the driving member recorded in the above embodiment before the structural adjustment is a motor, which can be replaced by:

[0039] The driving member includes a impeller gear (not shown in the figure) fixedly connected to the impeller 2, a handle gear (not shown in the figure) drivingly connected to the impeller gear, and a handle (not shown in the figure) fixedly arranged on the handle gear. The handle is manually controlled to rotate the handle gear, and the impeller gear drives the impeller 2 to rotate. This embodiment can also achieve the effect that when the shoe moves between the impeller and the balance ring and the two ends of the shoe abut against the impeller and the balance ring respectively, the guidance of the guide part makes the shoe slide to a position where it is not subjected to the squeezing force applied by the balance ring, thereby avoiding damage to the shoe. These do not deviate from the principle of the present invention, and therefore will fall within the scope of protection of the present invention.

[0040] For example, in another alternative embodiment, the inner side surface of the guide portion recorded in the above embodiment before the structural adjustment is an inclined surface, which can be replaced by:

[0041] The inner side surface of the guide part is a convex curved surface or a concave curved surface (not shown in the figure). This embodiment can also achieve the effect that when the shoe moves between the impeller and the balance ring and the two ends of the shoe abut against the impeller and the balance ring respectively, the guidance of the guide part makes the shoe slide to a position where it is not subjected to the squeezing force applied by the balance ring, thereby avoiding the shoe from being damaged. These do not deviate from the principle of the present invention, and therefore will fall within the scope of protection of the present invention.

[0042] For example, in another alternative embodiment, the guide portion and the balance ring 3 described in the above embodiment before the structural adjustment may be integrally formed and replaced with:

[0043] The guide part is fixedly connected to the balance ring 3. This embodiment can also achieve the effect that when the shoe moves between the impeller and the balance ring and the two ends of the shoe abut against the impeller and the balance ring respectively, the guide of the guide part makes the shoe slide to a position where it is not subjected to the squeezing force applied by the balance ring, thereby avoiding the shoe from being damaged. These do not deviate from the principle of the present invention and therefore fall within the protection scope of the present invention.

[0044] For example, in another alternative embodiment, the guide portion and the balance ring 3 described in the above embodiment before the structural adjustment may be integrally formed and replaced with:

[0045] The guide part is integrally formed with or fixedly connected to the inner wall of the washing tub 1. This embodiment can also achieve the effect that when the shoe moves between the impeller and the balance ring and the two ends of the shoe abut against the impeller and the balance ring respectively, the guide of the guide part makes the shoe slide to a position where it is not subjected to the squeezing force applied by the balance ring, thereby avoiding damage to the shoe. These do not deviate from the principle of the present invention and therefore fall within the scope of protection of the present invention.

[0046] For example, in another alternative embodiment, the guide portion and the balance ring 3 described in the above embodiment before the structural adjustment may be integrally formed and replaced with:

[0047] The guide part is integrally formed or fixedly connected with the inner wall of the balance ring 3 and the washing bucket 1. This embodiment can also achieve the effect that when the shoe moves between the impeller and the balance ring and the two ends of the shoe abut against the impeller and the balance ring respectively, the guide of the guide part makes the shoe slide to a position where the shoe is not subjected to the squeezing force of the balance ring, thereby avoiding the shoe from being damaged. These do not deviate from the principle of the present invention, and therefore will fall within the protection scope of the present invention.

[0048] For example, in another alternative implementation, based on the above structure, further:

[0049] The balance ring 3 and / or the guide part are fixedly provided with a brush (not shown in the figure). By providing the brush, the washing effect of the shoe washing device can be improved. These do not deviate from the principle of the present invention, and therefore will fall within the protection scope of the present invention.

[0050] For example, in another alternative implementation, based on the above structure, further:

[0051] The guide part is made of an elastic material, such as rubber. When the guide part is made of an elastic material, the elasticity can be used to improve the guiding effect on the shoe. This embodiment can also achieve the effect that when the shoe moves between the impeller and the balance ring and the two ends of the shoe abut against the impeller and the balance ring respectively, the guidance of the guide part makes the shoe slide to a position where the shoe is not subjected to the squeezing force applied by the balance ring, thereby avoiding damage to the shoe and improving this effect. These do not deviate from the principles of the present invention and therefore fall within the scope of protection of the present invention.

[0052] For example, in another alternative implementation, based on the above structure, further:

[0053] like Figure 3-4 As shown, the guide portion includes a impeller guide 6, the impeller 2 includes an impeller body 21 and an impeller rib 22, the impeller rib 22 is fixedly arranged at the top of the impeller body 21, and the impeller guide 6 is fixedly arranged at the outer side of the impeller rib 22 and / or the top of the impeller body 21. The surface of the impeller guide 6 away from the impeller rib 22 is an inclined surface (which can also be replaced by a curved surface). From the top of the impeller guide 6 along the surface away from the impeller rib 22 to the bottom of the impeller guide 6, the distance between the surface of the impeller guide 6 away from the impeller rib 22 and the impeller rib 22 gradually increases.

[0054] This embodiment provides a pulsator guide 6, so that when the shoe moves between the pulsator and the balance ring and the two ends of the shoe abut against the pulsator and the balance ring respectively, since the pulsator guide 6 is an inclined surface, the shoe can slide over the current pulsator ribs under the guidance of the pulsator guide 6 to a position where the balancing ring does not apply a squeezing force (it can also be regarded as a position where the pulsator 2 does not apply a squeezing force), thereby avoiding the effect of damaging the shoe. These do not deviate from the principle of the present invention, and therefore will fall within the scope of protection of the present invention.

[0055] For example, in another alternative embodiment, the guide portion including the balance ring guide 4 in the embodiment before the structural adjustment described above may also be replaced by:

[0056] like Figure 3-4 As shown, the guide portion includes a impeller guide 6, the impeller 2 includes an impeller body 21 and an impeller rib 22, the impeller rib 22 is fixedly arranged at the top of the impeller body 21, and the impeller guide 6 is fixedly arranged at the outer side of the impeller rib 22 and / or the top of the impeller body 21. The surface of the impeller guide 6 away from the impeller 2 is an inclined surface (which can also be replaced by a curved surface). From the top of the impeller guide 6 along the surface away from the impeller rib 22 to the bottom of the impeller guide 6, the distance between the surface of the impeller guide 6 away from the impeller rib 22 and the impeller rib 22 gradually increases.

[0057] This embodiment provides a pulsator guide 6, so that when the shoe moves between the pulsator and the balance ring and the two ends of the shoe abut against the pulsator and the balance ring respectively, since the pulsator guide 6 is an inclined surface, the shoe can slide over the current pulsator ribs under the guidance of the pulsator guide 6 to a position where the balancing ring does not apply a squeezing force (it can also be regarded as a position where the pulsator 2 does not apply a squeezing force), thereby avoiding the effect of damaging the shoe. These do not deviate from the principle of the present invention, and therefore will fall within the scope of protection of the present invention.

[0058] For example, in another alternative embodiment, the balancing ring guide 4 described in the embodiment before the structural adjustment can also be set at the bottom of the balancing ring 3, the inner diameter of the guide portion gradually increases from top to bottom, and the inner side surface of the guide portion can be an inclined surface, which is replaced by:

[0059] like Figure 5 As shown, the guide part includes a balance ring guide 4, which is arranged at the bottom of the balance ring 3 and is a guide air bag; an air pump 7 is also arranged on the outside of the washing tub, and the output end of the air pump 7 is connected to the guide air bag; and a deflation valve (not shown in the figure) is also arranged on the guide air bag. Figure 5 When the shoe moves between the impeller 2 and the balance ring 3 and the two ends of the shoe abut against the impeller 2 and the balance ring 3 respectively, the shoe exerts a force on the guide airbag. Since the guide airbag is elastic and filled with gas, the guide airbag deforms elastically after being acted upon by the external force, so that the shoe can be guided by the guide airbag, so that the shoe slides to a position where it is not squeezed by the balance ring 3. 。

[0060] In this embodiment, the number of air pumps 7 can be two or more (not shown in the figure), and the multiple air pumps 7 are evenly distributed. Of course, the number of air pumps 7 can also be one (not shown in the figure). In this case, in order to keep the washing tub 1 balanced during the dehydration rotation, a balance block (not shown in the figure) with the same weight as the air pump 7 can be set at a position symmetrical to the air pump 7 in the washing tub 1.

[0061] The balance ring guide 4 described in the embodiment before the structural adjustment is set at the bottom of the balance ring 3, which can achieve the effect of avoiding the shoes from being squeezed and damaged. However, it is obvious that the balance ring guide 4 also occupies the space inside the washing tub 1 to a certain extent. When the shoes are not stuck and rotate in the washing tub 1, the balance ring guide 4 will have a certain obstruction on the washing effect. Therefore, in this embodiment, the balance ring guide 4 is a guide airbag, and according to the actual situation, the guide airbag can be inflated to achieve the effect of guiding the shoes, and the guide airbag can be deflated to reduce the space occupied by the balance ring guide 4 inside the washing tub 1.

[0062] Furthermore, a pressure sensor (not shown in the figure) can also be arranged inside the guide airbag, and the pressure sensor can feed back the stress condition of the guide airbag to the air pump 7. The pressure sensor, the air pump 7 and the deflation valve (which can be a solenoid valve) are all connected to a controller (not shown in the figure, which can be a controller provided by the shoe washing device, or an external server, etc.). The inflation and deflation of the guide airbag can be flexibly controlled according to the stress condition of the guide airbag, so as to achieve a better washing effect and reduce the damage to the shoes during the washing process. These do not deviate from the principles of the present invention, and therefore will fall within the scope of protection of the present invention.

[0063] For example, in another alternative implementation, based on the above structure, further:

[0064] A washing air bag (not shown in the figure) is fixedly arranged on the inner wall of the washing bucket, and an air pump 7 is arranged on the outer side of the washing bucket, and the output end of the air pump 7 is connected to the washing air bag; an air release valve (not shown in the figure) is also arranged on the washing air bag. In this embodiment, according to the specific washing situation, by controlling the inflation amount and deflation amount of the washing air bag, the washing air bag can be expanded and contracted to different degrees, and combined with the elastic characteristics of the washing air bag itself, the washing effect on the shoes can be improved.

[0065] Furthermore, a pressure sensor (not shown in the figure) is also provided inside the washing airbag, and the pressure sensor can feed back the force of the washing airbag to the air pump 7. The pressure sensor, the air pump 7 and the air release valve are all connected to a controller (not shown in the figure, which can be a controller provided by the shoe washing device or an external server, etc.). In this embodiment, the amount of gas in the washing airbag can be controlled according to the detection of the pressure sensor in the washing airbag, so as to achieve the expansion and contraction of the washing airbag, thereby improving the washing effect on the shoes.

[0066] Furthermore, in order to further improve the washing effect, bristles (not shown in the figure) can be fixedly arranged on the outer surface of the washing airbag. These do not deviate from the principle of the present invention, and therefore will fall within the scope of protection of the present invention.

[0067] For example, in another alternative implementation, based on the above structure, further:

[0068] A ball brush (not shown) is also fixedly arranged on the top of the impeller 2. This embodiment can further improve the washing effect of the shoe washing device. These do not deviate from the principle of the present invention, and therefore will fall within the protection scope of the present invention.

[0069] Of course, the above-mentioned replaceable embodiments, as well as the replaceable embodiments and the preferred embodiments, can be used in a cross-coordinated manner to combine new embodiments to be suitable for more specific application scenarios.

[0070] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
