[0032] Many specific details are described in the following description to facilitate a full understanding of this specification. However, this specification can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of this specification, so this specification is not limited to the specific implementation disclosed below.

[0033] The terms used in one or more embodiments of this specification are only for the purpose of describing specific embodiments, and are not intended to limit one or more embodiments of this specification. The singular forms of "a" and "the" used in one or more embodiments of this specification and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used in one or more embodiments of this specification refers to and includes any or all possible combinations of one or more associated listed items.

[0034] It should be understood that although the terms first, second, etc. may be used to describe various information in one or more embodiments of this specification, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of this specification, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0035] It should be noted that with the further upgrade of cleaning equipment, it can meet the needs of users in a variety of scenarios such as kitchen, sofa, ironing clothes, etc., but different cleaning brushes are required for different usage scenarios. Among them, according to statistics, there are more than a dozen electric and non-electric cleaning brushes. How to quickly distinguish cleaning brushes to avoid users using the wrong cleaning brush is particularly important.

[0036] At present, the current is often sampled after the cleaning brush is connected to the cleaning device, and the type of cleaning brush connected to the cleaning device is determined by using the obtained current. However, in the above method, when distinguishing the type of electric cleaning brush, it is necessary to wait for the motor speed to stabilize before detection, which has a delayed response and low cleaning brush detection efficiency. In addition, the current difference between different types of cleaning brushes is small and difficult to distinguish, resulting in a high probability of misjudgment and low cleaning brush identification accuracy. When distinguishing the type of non-electric cleaning brush, it is necessary to add resistance for distinction, which is costly.

[0037] Therefore, in the embodiment of the present specification, a set number of first contacts are set on the device body of the cleaning device, and corresponding at least two second contacts are set on the cleaning brush. When the user connects the cleaning brush to the cleaning device and presses the start button, the conductivity between the contacts can be scanned by the identification unit. Combined with the set contact correspondence of the cleaning brush, the type of the currently connected cleaning brush can be quickly identified without waiting for the motor speed to stabilize, thereby improving the efficiency of identifying the cleaning brush type, avoiding misjudgment, and improving the recognition accuracy. It is suitable for the identification of various types of cleaning brushes such as electric and non-electric, and there is no need to increase resistance for identification of a separate non-electric cleaning brush, thereby reducing costs.

[0038] In this specification, a method for identifying the type of cleaning brush is provided. This specification also involves a cleaning brush type identification unit, a cleaning brush type identification circuit, a cleaning device, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0039] Figure 1 A flow chart of a method for identifying a type of cleaning brush provided according to an embodiment of the present specification is shown, which is applied to a cleaning device, wherein a set number of first contacts are provided on the device body of the cleaning device, and at least two second contacts are provided on the cleaning brush, wherein the second contacts correspond to any first contacts, and the corresponding relationships of the contacts of different types of cleaning brushes are different. The method specifically includes the following steps 102-106:

[0040] Step 102: When the cleaning brush is connected to the device body of the cleaning device, a first electrical level is output to a target contact on the device body, wherein the target contact is any first contact provided on the device body.

[0041] It should be noted that cleaning equipment refers to intelligent equipment with cleaning functions, such as floor cleaning machines, fabric cleaning machines, sweeping and mopping machines, window cleaning robots, etc. Cleaning brushes refer to brush heads that need to be connected to the main body of the cleaning equipment to clean the corresponding media. Different cleaning brushes need to be connected in different usage scenarios. According to statistics, there are as many as a dozen electric and non-electric cleaning brushes corresponding to a type of cleaning equipment. It is particularly important to quickly distinguish cleaning brushes to prevent users from using the wrong cleaning brushes.

[0042] In an embodiment of the present specification, a set number of first contacts can be set on the device body of the cleaning device and at the connection position with the cleaning brush, and then at least two second contacts can be set at the connection position between the cleaning brush and the device body of the cleaning device. Among the at least two second contacts, two second contacts correspond to any first contact position, and the remaining contact positions may not correspond, so that the corresponding two first contacts can be conductive. The correspondence between the second contacts on different types of cleaning brushes and the first contacts on the device body is different, that is, different types of cleaning brushes can detect different conductive contacts, so that the type of cleaning brush currently connected can be quickly identified through the conductive contacts.

[0043] In actual applications, when the cleaning brush is connected to the device body, the two first contacts corresponding to the second contact can be turned on, so that the identification unit can determine the turned-on first contacts by scanning the levels of the various first contacts, thereby identifying and determining the target cleaning brush type of the currently connected cleaning brush. In specific implementation, after the user connects the cleaning brush to the device body of the cleaning device and presses the start button, the identification unit can detect the corresponding access signal and determine that the cleaning brush is connected to the device body of the cleaning device. At this time, the identification unit can output the first level to the target contact on the device body, and subsequently determine whether there are other first contacts that are turned on by detecting the second levels of other first contacts on the device body, thereby identifying the type of the cleaning brush.

[0044] The target contact may be any first contact provided on the device body, and each first contact on the device body may serve as the target contact, so as to detect whether other first contacts are connected to the target contact based on the target contact.

[0045] In addition, the first level can be a level of any voltage value, that is, a high level, such as 3.3V, 5.5V, etc., and subsequently, it is only necessary to detect whether other first contacts are also at the first level to determine whether other first contacts are connected to the target contact.

[0046] For example, Figure 2 is a schematic diagram of the distribution of a first contact and a second contact provided in an embodiment of this specification, such as Figure 2 As shown, six first contacts are arranged on the device body of the cleaning device, namely contacts X1, X2, X3, X4, X5 and X6; two second contacts are arranged on the first type of cleaning brush, namely contacts Y1 and Y2, and the positions of Y1 and Y2 correspond to those of X1 and X2; two second contacts are arranged on the second type of cleaning brush, namely contacts Y3 and Y5, and the positions of Y3 and Y5 correspond to those of X3 and X5; two second contacts are arranged on the third type of cleaning brush, namely contacts Y2 and Y6, and the positions of Y2 and Y6 correspond to those of X2 and X6.

[0047] When the cleaning brush is connected to the device body of the cleaning device, assuming that contact X1 is used as the target contact, the identification unit can output a high level to contact X1; assuming that contact X2 is used as the target contact, the identification unit can output a high level to contact X2, and so on.

[0048] In the embodiment of the present specification, the number of contacts that need to be set on the device body can also be predetermined, that is, when the cleaning brush is connected to the device body of the cleaning device, before the first level is output to the target contact on the device body, the method further includes:

[0049] Determining the number of candidate cleaning brush types for the cleaning device;

[0050] The setting value is determined according to the number of types, wherein the setting value is the number of contacts to be set.

[0051] It should be noted that, for a certain type of cleaning equipment, the number of contacts set on the equipment body of the cleaning equipment, and the number of combination relationships obtained after combining two by two and excluding repeated combinations, need to meet the number of types of cleaning brushes corresponding to this type of cleaning equipment, so that the corresponding cleaning brush type can be indicated by combining two by two contacts.

[0052] In practical applications, the number of candidate cleaning brush types of the cleaning device can be determined first, that is, the number of cleaning brushes that the cleaning device has for the user to choose from, and then based on the number of types, the number of contacts that need to be set on the device body can be determined, that is, the set value. In specific implementation, the number of combination relationships obtained by combining two by two can satisfy the minimum value of the number of candidate cleaning brush types, and the minimum value is used as the set value, and the set value of first contacts is set on the device body of the cleaning device. The position of the set value of first contacts can be set arbitrarily, as long as the position of the second contact on the cleaning brush corresponds to the position of any two of the first contacts.

[0053] In actual implementation, the number of combination relationships that can be obtained by combining two target values ​​can be calculated using the following formula (1):

[0054]

[0055] Here, C refers to combination, which is a mathematical term. Generally speaking, taking any two elements from m different elements as a group is called a combination of two elements from m different elements.

[0056] In addition, "!" represents factorial, P represents the obtained combination relationship number, and m represents the target value. The minimum target value m that satisfies the combination relationship number P greater than or equal to the number of candidate cleaning brush types is used as the set value.

[0057] For example, taking a fabric washing machine as an example, there are twelve optional cleaning brushes, that is, the number of candidate cleaning brush types is 12. When m is 3, the combination relationship number P is 3, which is less than 12; when m is 4, the combination relationship number P is 6, which is less than 12; when m is 5, the combination relationship number P is 10, which is less than 12; when m is 6, the combination relationship number P is 15, which is greater than 12. Therefore, it can be determined that the minimum number of candidate cleaning brush types that satisfies the combination relationship number P greater than or equal to 12 is 6. At this time, the set value can be determined to be 6, and 6 contacts can be set on the device body.

[0058] In the embodiments of the present specification, the number of contacts that need to be set on the device body can be determined based on the number of types of candidate cleaning brushes, so that the number of combination relationships of the first contacts set on the device body in pairs can meet the requirements for indicating the types of candidate cleaning brushes without setting too many contacts, thereby ensuring that various types of cleaning brushes can be indicated by corresponding contact combination relationships, thereby ensuring the success rate of cleaning brush type detection, and without setting and detecting too many contacts, saving costs and improving detection efficiency.

[0059] In an optional implementation of this embodiment, a contact correspondence table between the cleaning brush type and the contact conduction relationship of the first contact may be pre-configured and stored, that is, when the cleaning brush is connected to the device body of the cleaning device, before the first level is output to the target contact on the device body, the method further includes:

[0060] Determine various combination relationships corresponding to the set values, and use the contact point combination corresponding to the combination relationship as the contact point conduction relationship;

[0061] For the first cleaning brush type, a corresponding first contact conduction relationship is selected from various contact conduction relationships, and the first cleaning brush type and the first contact conduction relationship are stored correspondingly, wherein the first cleaning brush type is any candidate cleaning brush type;

[0062] Based on the types of cleaning brushes and the corresponding contact conduction relationships, a contact correspondence relationship table is generated, wherein the contact correspondence relationship table is used to indicate that the second contact corresponding to the contact conduction relationship is set on the cleaning brush of the corresponding type.

[0063] In practical applications, various combination relationships corresponding to the set values ​​can be determined, and the contact combinations corresponding to the combination relationships are used as contact conduction relationships. Then, corresponding cleaning brush types are configured for various contact conduction relationships, and the contact conduction relationships and cleaning brush types are stored in correspondence to obtain a contact correspondence relationship table of contact conduction relationships and cleaning brush types. Then, based on the contact correspondence relationship table, second contacts at corresponding positions can be set on various types of cleaning brushes.

[0064] In specific implementation, when configuring corresponding cleaning brush types for various contact conduction relationships, the configuration may be random or in accordance with set rules, and different cleaning brush types need to be configured with different contact conduction relationships.

[0065] Using the above example, the value is set to 6, and the corresponding combinations include: 12, 13, 14, 15, 16, 23, 24, 25, 26, 34, 35, 36, 45, 46, 56, which means that the contact conduction relationships include: the first contact and the second contact are conductive, the first contact and the third contact are conductive, the first contact and the fourth contact are conductive, the first contact and the fifth contact are conductive, and the first contact is conductive. The 2nd contact is connected to the 3rd contact, the 2nd contact is connected to the 4th contact, the 2nd contact is connected to the 5th contact, the 2nd contact is connected to the 6th contact, the 3rd contact is connected to the 4th contact, the 3rd contact is connected to the 5th contact, the 3rd contact is connected to the 6th contact, the 4th contact is connected to the 5th contact, the 4th contact is connected to the 6th contact, and the 5th contact is connected to the 6th contact. Assuming that there are 12 types of cleaning brushes, a contact conduction relationship is randomly selected from type 1 to type 12, and different types of contact conduction relationships are selected. The contact correspondence table shown in Table 1 below can be obtained.

[0066] Table 1 Contact correspondence table

[0067]

[0068]

[0069] Based on Table 1 above, two second contacts corresponding to the positions of the first contact and the second contact on the device body are set on the cleaning brush of type 1; two second contacts corresponding to the positions of the first contact and the third contact on the device body are set on the cleaning brush of type 2; two second contacts corresponding to the positions of the first contact and the fourth contact on the device body are set on the cleaning brush of type 3, and so on, and corresponding second contacts are set at corresponding positions on each type of cleaning brush.

[0070] In the embodiments of the present specification, corresponding contact conduction relationships can be pre-configured for each cleaning brush type, and a contact correspondence table can be generated and stored so that after a subsequent identification unit detects the first conductive contact, the contact correspondence table can be queried to quickly and accurately determine the target cleaning brush type of the currently connected cleaning brush.

[0071] In an optional implementation of this embodiment, outputting a first level to a target contact on the device body includes:

[0072] A first level is output to the i-th contact of the device body, where i is a positive integer.

[0073] It should be noted that one of the first contacts set on the device body can be selected as the target contact. In specific implementation, the i-th contact on the device body can be selected as the target contact, and the i-th contact is used as a reference to detect whether other contacts on the device body are connected to the i-th contact, where i is a positive integer.

[0074] In an optional implementation of this embodiment, before outputting the first level to the i-th contact of the device body, the method further includes:

[0075] According to the position of the first contact of the set value, number the first contact of the set value;

[0076] The starting number of the first contact of the set value is used as the initial value of i.

[0077] It should be noted that each first contact can be numbered according to the position of the set value of first contacts and the pre-configured numbering rule. The numbering rule can be a pre-configured rule for numbering the set value of first contacts, such as numbering from left to right, from top to bottom, or from top to bottom, from left to right. In addition, in a specific implementation, the set value of first contacts can be numbered randomly instead of based on the position, and this specification does not limit this.

[0078] In practical applications, after numbering the first contact of a set value, the starting number of the first contact of the set value can be used as the initial value of i. For example, if the contacts of the set value are numbered starting from 1, the initial value of i is 1; if the contacts of the set value are numbered starting from 5, the initial value of i is 5.

[0079] In the embodiment of the present specification, starting from the contact indicated by the starting number among the set number of contacts, it is possible to detect in sequence whether the subsequent contacts are connected to the contact, thereby quickly and accurately identifying the target cleaning brush type of the currently connected cleaning brush.

[0080] Step 104: Detect the second level of other contacts on the device body except the target contact, and determine the conductive contact according to the first level and the second level.

[0081] It should be noted that after the identification unit outputs the first level to the target contact, the second levels of other contacts on the device body except the target contact can be detected in turn. If the second level of another contact is consistent with the first level, it means that the other contact is connected to the target contact; if the second level of each other contact is inconsistent with the first level, the next first contact set on the device body can be selected as the target contact, and then the second levels of other contacts on the device body except the target contact can be detected based on the target contact to determine whether other contacts are connected to the target contact.

[0082] In actual applications, each first contact point may be traversed, and the process ends after the traversal is completed; or, if it is detected that some other contact point is connected to the current target contact point, the process ends directly.

[0083] In an optional implementation of this embodiment, detecting the second level of other contacts on the device body except the target contact, and determining the conductive contact according to the first level and the second level includes:

[0084] Detecting the second level of other contacts after the i-th contact on the device body, and determining whether there is a conductive contact according to the first level and the second level;

[0085] If there is no conducting contact, i is incremented by 1, and the process returns to the step of outputting the first level to the i-th contact of the device body until there is a conducting contact or i is equal to the set value.

[0086] It should be noted that i is initially the starting number of the first contact with a set value. The identification unit can output a first level to the i-th contact of the device body, and then detect the second levels of other contacts after the i-th contact through the I / O (Input / Output) port, and determine whether there is a conductive contact based on whether the first level and the second level are consistent.

[0087] In actual applications, if there is a conductive contact, the process can end directly, and then query the corresponding target cleaning brush type based on the conductive contact. If there is no conductive contact, i can be incremented by 1. If i is not equal to the set value, the process returns to the step of outputting the first level to the i-th contact of the device body until there is a conductive contact. Then, based on the conductive contact, query the corresponding target cleaning brush type; if i is equal to the set value, it means that all the first contacts on the device body have been detected as target contacts, and no other first contacts are conductive with the target contact. It is possible that the currently connected cleaning brush is not compatible, or the contact position does not correspond due to damage, and the target cleaning brush type cannot be detected. At this time, an alarm message can be returned, so that the user can judge whether the cleaning brush is connected incorrectly or whether the cleaning brush is damaged based on the alarm message.

[0088] In the embodiment of the present specification, after the identification unit outputs the first level to the ith contact of the device body, the second level of other contacts after the ith contact on the device body can be detected in sequence to determine whether there are other contacts after the ith contact that are conductive with the ith contact. If not, the next first contact is used as the ith contact, and the detection continues until a conductive contact is detected or the traversal ends. In this way, it is possible to detect which two contacts are conductive among the set value of first contacts set on the device body, so as to facilitate the subsequent query of the corresponding target cleaning brush type. By detecting the conductivity between the contacts, the type of cleaning brush currently connected can be quickly identified in combination with the corresponding relationship of the contacts of the cleaning brush, without waiting for the motor speed to stabilize, thereby improving the recognition efficiency of the cleaning brush type, avoiding misjudgment, and improving the recognition accuracy. It is suitable for the recognition of various types of cleaning brushes such as electric and non-electric, and there is no need to increase resistance for identification of a separate non-electric cleaning brush, thereby reducing costs.

[0089] In an optional implementation of this embodiment, detecting the second level of other contacts after the i-th contact on the device body, and determining whether there is a conductive contact according to the first level and the second level, includes:

[0090] detecting a second level of a j-th contact on the device body, wherein j is greater than i;

[0091] If the second level of the j-th contact is consistent with the first level, it is determined that the i-th contact and the j-th contact are conductive, and the conductive contacts are recorded as the i-th contact and the j-th contact;

[0092] If the second level of the jth contact is inconsistent with the first level, it is determined that the ith contact and the jth contact are not conductive, j is incremented by 1, and the step of detecting the second level of the jth contact on the device body is returned until j is equal to the set value.

[0093] In actual applications, the identification unit can output a first level to the i-th contact of the device body, and then detect the second level of the j-th contact on the device body, where j is greater than i. If the second level of the j-th contact is consistent with the first level, it means that the i-th contact and the j-th contact are conducting. At this time, the conducting contacts can be recorded as the i-th contact and the j-th contact, and the process ends. If the second level of the j-th contact is inconsistent with the first level, it means that the i-th contact and the j-th contact are not conducting. At this time, let j increase by 1. If j is not equal to the set value, return to the step of executing the second level of the j-th contact on the device body, and continue to judge whether the next contact is conducting with the i-th contact, until j is equal to the set value, indicating that all other contacts after the i-th contact have been detected. At this time, i can be incremented by 1, and the next contact on the device body is continued as the i-th contact, and continue to detect whether there are other contacts conducting thereafter.

[0094] For example, assuming that there are 6 contacts on the device body, the identification unit outputs a high level to the first contact on the device body, detects whether the second contact on the device body is at a high level, and if so, records the conductive contacts as the first and second contacts, and ends the process; if not, continues to detect whether the third contact is at a high level, and so on, until the sixth contact is still not at a high level. Then, output a high level to the second contact, detect whether the third contact on the device body is at a high level, and if so, records the conductive contacts as the second and third contacts, and ends the process; if not, continues to detect whether the fourth contact is at a high level, and so on, until the sixth contact is still not at a high level. After that, continue to output a high level to the third contact, and so on, until the conductive contact is determined, or a high level is output to the fifth contact, and the sixth contact is still not at a high level. At this time, since i+1 is 6, which is equal to the set value, the process ends and an alarm message is issued.

[0095] In the embodiments of the present specification, the other contacts after the ith contact are traversed in sequence to detect whether there are other contacts that are conductive with the ith contact, so that the type of the currently connected cleaning brush can be quickly identified based on the detected conductive contacts and the contact correspondence of the cleaning brush. There is no need to wait for the motor speed to stabilize, which improves the efficiency of identifying the cleaning brush type and avoids misjudgment, thereby improving the recognition accuracy. It is suitable for the identification of various types of cleaning brushes, such as electric and non-electric, and there is no need to increase resistance for identification of a separate non-electric cleaning brush, thereby reducing costs.

[0096] Step 106: Determine the target cleaning brush type connected to the device body according to the conductive contacts and the contact correspondence.

[0097] It should be noted that the contact correspondence refers to the correspondence between the contact conduction relationship and the cleaning brush type. Therefore, after the conduction contacts are determined, the conduction contacts and the contact correspondence can be combined to determine the target cleaning brush type connected to the device body.

[0098] In an optional implementation of this embodiment, determining the type of a target cleaning brush connected to the device body according to the corresponding relationship between the conductive contacts and the contacts includes:

[0099] In the contact correspondence table of contact conduction relationships and cleaning brush types, query the target cleaning brush type corresponding to the conduction contact.

[0100] It should be noted that the target cleaning brush type corresponding to the determined conductive contact may be queried in a pre-stored contact correspondence table of contact conductive relationships and cleaning brush types.

[0101] Continuing with the above example, the contact correspondence table stored in the identification unit is shown in Table 1 above. Assuming that the conductive contacts determined are the 2nd and 5th contacts, the corresponding target cleaning brush type can be queried through Table 1 above to be type 8, that is, the device body currently connected to the cleaning device is a type 8 cleaning brush.

[0102] The method for identifying the type of cleaning brush provided in the embodiment of the present specification realizes setting a set value of first contacts on the device body of the cleaning device, and setting corresponding at least two second contacts on the cleaning brush. The corresponding relationship of the contacts of different types of cleaning brushes is different. Therefore, when the cleaning brush is connected to the cleaning device body, a first level can be output to a first contact on the device body, and then the second levels of other first contacts are detected in sequence. Based on the first level and the second level, it can be determined whether the two first contacts are conductive, so as to determine the type of the currently connected target cleaning brush based on the conductive contacts and the contact correspondence. In this way, the second contact corresponds to at least two first contacts. After the second contact contacts the corresponding first contact, the corresponding first contacts are conductive. Therefore, by detecting the conductive state between the contacts, the type of the currently connected cleaning brush can be quickly identified in combination with the contact correspondence of the cleaning brush, without waiting for the motor speed to stabilize, thereby improving the efficiency of the identification of the cleaning brush type, avoiding misjudgment, and improving the identification accuracy. It is suitable for the identification of various types of cleaning brushes such as electric and non-electric, and there is no need to increase the resistance of the non-electric cleaning brush for identification, thereby reducing the cost.

[0103] It should be noted that fabric cleaning machines are generally used to clean fabric sofas, curtains and other fabric products. They spray water or cleaning liquid on the dirty surface, then clean the dirty surface with a handheld cleaning brush and suck the cleaned sewage into the sewage tank through the suction port to achieve local cleaning of fabric products, which is relatively convenient to use. With the further upgrade of fabric cleaning machines, they can meet the needs of users in a variety of scenarios such as kitchens, sofas, and ironing clothes. However, different cleaning brushes are required for different usage scenarios. How to quickly distinguish cleaning brushes to avoid users using the wrong cleaning brushes is particularly important.

[0104] The following combination Figure 3 Taking the application of the cleaning brush type identification method provided in this specification in a fabric cleaning machine as an example, the cleaning brush type identification method is further described. Figure 3 A processing flow chart of a method for identifying the type of cleaning brush applied to a fabric cleaning machine provided in an embodiment of the present specification is shown, which specifically includes the following steps:

[0105] Step 302: The identification unit determines the number of candidate brush head types for the fabric cleaning machine, determines a set value based on the number of types, and a staff member sets a first contact point of the set value at a location connected to the brush head on the equipment body of the fabric cleaning machine.

[0106] Step 304: The identification unit determines various combination relationships corresponding to the set value, and takes the contact combination corresponding to the combination relationship as the contact conduction relationship; for each brush head type, the corresponding contact conduction relationship is selected respectively, and a contact correspondence table is generated. Different brush head types have different corresponding contact conduction relationships; the user sets the second contact on the corresponding type of brush head based on the contact position indicated by the corresponding contact conduction relationship.

[0107] Step 306: The identification unit detects the connection position of the brush head connected to the fabric cleaning machine.

[0108] Step 308: Output a high level to the i-th contact of the device body.

[0109] Step 310: Detect the second level of the j-th contact on the device body.

[0110] Step 312: Determine whether the second level is consistent with the first level. If they are consistent, execute the following step 314; if they are inconsistent, execute the following step 316.

[0111] Step 314: Record the conductive contacts as the i-th contact and the j-th contact, and execute the following step 320.

[0112] Step 316: Increment j by 1. If j is not equal to the set value, return to step 310; if j is equal to the set value, execute the following step 318.

[0113] Step 318: Increment i by 1. If i is not equal to the set value, return to step 308 and execute the following step 320 until there is a conductive contact. Alternatively, if i is equal to the set value, the process ends.

[0114] Step 320: Determine the type of brush head connected to the device body according to the conductive contacts and the contact correspondence.

[0115] The method for identifying the type of cleaning brush provided in the embodiment of this specification realizes setting a set value of first contacts on the device body of the fabric cleaning machine, and setting corresponding at least two second contacts on the brush head. The corresponding relationship of the contacts of different types of brush heads is different. Therefore, when the brush head is connected to the device body of the fabric cleaning machine, a first level can be output to a first contact on the device body, and then the second levels of other first contacts are detected in sequence. Based on the first level and the second level, it can be determined whether the two first contacts are conductive, so as to determine the type of brush head currently connected based on the conductive contacts and the contact correspondence. In this way, the second contact corresponds to at least two first contacts. After the second contact contacts the corresponding first contact, the corresponding first contacts are conductive. Therefore, by detecting the conductive state between the contacts, the type of brush head currently connected can be quickly identified in combination with the contact correspondence of the brush head, without waiting for the motor speed to stabilize, thereby improving the recognition efficiency of the brush head type, avoiding misjudgment, and improving the recognition accuracy. It is suitable for the recognition of various types of brush heads such as electric and non-electric, and there is no need to increase resistance for identification of a single non-electric brush head, thereby reducing costs.

[0138] Based on the types of cleaning brushes and the corresponding contact conduction relationships, a contact correspondence relationship table is generated, wherein the contact correspondence relationship table is used to indicate that the second contact corresponding to the contact conduction relationship is set on the cleaning brush of the corresponding type.

[0139] Optionally, the second determining module 406 is further configured to:

[0140] In the contact correspondence table of contact conduction relationships and cleaning brush types, query the target cleaning brush type corresponding to the conduction contact.

[0141] The cleaning brush type identification unit provided in the embodiment of the present specification realizes setting a set value of first contacts on the device body of the cleaning device, and setting corresponding at least two second contacts on the cleaning brush. The corresponding relationship of the contacts of different types of cleaning brushes is different. Therefore, when the cleaning brush is connected to the cleaning device body, a first level can be output to a first contact on the device body, and then the second levels of other first contacts are detected in sequence. Based on the first level and the second level, it can be determined whether the two first contacts are conductive, so as to determine the type of the currently connected target cleaning brush based on the conductive contacts and the contact correspondence. In this way, the second contact corresponds to at least two first contacts. After the second contact contacts the corresponding first contact, the corresponding first contacts are conductive. Therefore, by detecting the conductive state between the contacts, the type of the currently connected cleaning brush can be quickly identified in combination with the contact correspondence of the cleaning brush, without waiting for the motor speed to stabilize, thereby improving the recognition efficiency of the cleaning brush type, avoiding misjudgment, and improving the recognition accuracy.
