Specific embodiments

[0036] ​​​In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0037] In the related art, the spray gun is driven by the motor through the gear and rack mechanism, so that the spray gun can be extended or retracted from the shell. The motor is arranged inside the shell, which causes the motor to be in high temperature and high humidity working conditions for a long time, which can accelerate the aging of the motor insulation material or sealing material, and the rust of the metal parts, affecting the service life of the motor.

[0038] However, if the motor is arranged outside the shell, the shell needs to be provided with an opening for the gear and rack mechanism to pass through. There must be a gap between the gear and rack mechanism and the opening, so that high temperature steam can easily leak, affecting the sterilization effect.

[0039] In order to solve or improve the problem that the motor is arranged inside the shell and is prone to aging or rust, or the problem that the motor is arranged outside the shell and is prone to steam leakage, the utility model embodiments provide a spray gun assembly and a closestool.

[0040] The spray gun assembly provided in the embodiments of the utility model will be described below in combination with Figures 1 to 6 The spray gun assembly provided in the embodiments of the utility model will be described below in combination with

[0041] Specifically, the spray gun assembly comprises a support 1, a spray gun 2, a cover 3, a first transmission member 4 and a driving assembly 5.

[0042] The support 1 is internally provided with a containing cavity 101 for containing the spray gun 2. The support 1 is provided with an access opening 102 for the spray gun 2 to enter or exit the containing cavity 101, and obviously, the access opening 102 is in communication with the containing cavity 101.

[0043] The spray gun 2 is in sliding connection with the support 1, and the spray gun 2 can be extended or retracted into the containing cavity 101. The part of the spray gun 2 extended out of the containing cavity 101 is provided with a spray opening 201 for spraying cleaning liquid, which includes but is not limited to water. It can be understood that when the user needs to clean, the spray gun 2 should be able to extend out of the containing cavity 101, and after the cleaning is completed, the spray gun 2 should be able to retract into the containing cavity 101, so as to disinfect the spray gun 2.

[0044] The cover 3 is arranged in the access opening 102 in an openable and closable manner, so that the cover 3 can open the access opening 102 when the spray gun 2 is extended out of the containing cavity 101, and close the access opening 102 after the spray gun 2 is retracted into the containing cavity 101.

[0045] The first transmission member 4 is connected to the spray gun 2, for example, by being bonded, interference fitted or clamped to the spray gun 2.

[0046] The driving assembly 5 is reciprocally arranged outside the support 1 and is magnetically attracted to the first transmission member 4, so that the driving assembly 5 can drive the first transmission member 4 to move by magnetic force. It can be understood that the driving assembly 5 can move towards the direction in which the spray gun 2 extends or towards the direction in which the spray gun 2 retracts. Alternatively, the driving assembly 5 and the first transmission member 4 are both magnets, or one of the driving assembly 5 and the first transmission member 4 is a magnet and the other is an iron block. For example, the magnet can be a permanent magnet or an electromagnet.

[0047] In this embodiment, when it is needed to clean by using the spray gun 2, the driving assembly 5 is controlled to move towards the direction in which the spray gun 2 extends, and the driving assembly 5 drives the first transmission member 4 to move by magnetic force, so that the first transmission member 4 drives the spray gun 2 to extend out of the accommodating cavity 101, and the spray gun 2 can spray cleaning liquid to perform cleaning work.

[0048] After the spray gun 2 is used, the driving assembly 5 is controlled to move towards the direction in which the spray gun 2 retracts, and the driving assembly 5 drives the first transmission member 4 to move by magnetic force, so that the first transmission member 4 drives the spray gun 2 to retract into the accommodating cavity 101. The cover 3 is closed to cover the entrance 102, and the steam generator 6 is controlled to introduce steam into the accommodating cavity 101 through the air inlet 103, so as to sterilize the spray gun 2. The steam outlet 104 can discharge steam to keep the pressure balance between the inside and outside of the accommodating cavity 101.

[0049] In this way, in the spray gun assembly provided by the embodiment, the driving assembly 5 and the first transmission member 4 on the spray gun 2 are magnetically attracted, so that the driving assembly 5 can drive the first transmission member 4 to move by magnetic force, and then the first transmission member 4 drives the spray gun 2 to move, so that the spray gun 2 extends out of or retracts into the accommodating cavity 101 of the support 1, and then the spray gun 2 can be driven by the driving assembly 5 to extend out or retract without being in contact with the driving assembly 5.

[0050] As described above, the driving assembly 5 and the spray gun 2 are magnetically attracted to drive each other, without being in contact, so that the driving assembly 5 does not need to be arranged in the accommodating cavity 101, thereby solving the problem that the motor is arranged inside the shell in the related art and is prone to aging or rust.

[0051] In addition, although the driving assembly 5 is arranged outside the accommodating cavity 101, the support 1 does not need to be provided with a through hole to avoid the first transmission member 4 or the driving assembly 5, thereby solving the problem that the motor is arranged outside the shell in the related art and is prone to steam leakage.

[0052] In some embodiments of the utility model, the support 1 is further provided with an air inlet 103 and an air outlet 104.

[0053] The air inlet 103 is used to be connected with the steam generator 6, so that the steam generated by the steam generator 6 can enter the containing cavity 101 through the air inlet 103. The air outlet 104 is used for steam in the containing cavity 101 to be discharged, so as to maintain the pressure balance between the containing cavity 101 and the outside, and enable the steam generated by the steam generator 6 to enter the containing cavity 101 continuously.

[0054] In some embodiments of the utility model, the driving assembly 5 comprises a driving piece 501 and a second transmission piece 502.

[0055] The driving piece 501 is reciprocally movably arranged outside the support 1, for example, the driving piece 501 can move towards the direction of the spray gun 2 extending, or can move towards the direction of the spray gun 2 retracting. The second transmission piece 502 is connected with the driving piece 501, for example, the second transmission piece 502 is bonded, interference connected or clamped connected with the driving piece 501.

[0056] The second transmission piece 502 and the first transmission piece 4 are attracted to each other by magnetic force, so that the driving piece 501 can drive the first transmission piece 4 to move through the second transmission piece 502. Alternatively, the second transmission piece 502 and the first transmission piece 4 are both magnets, or one of the second transmission piece 502 and the first transmission piece 4 is a magnet, and the other is an iron block. For example, the magnet can be a permanent magnet or an electromagnet.

[0057] In the embodiment, when it is needed to clean by using the spray gun 2, the driving piece 501 is controlled to move towards the direction of driving the spray gun 2 to extend, and the second transmission piece 502 moves the first transmission piece 4 by magnetic force during the movement of the driving piece 501, so that the first transmission piece 4 drives the spray gun 2 to extend out of the containing cavity 101, and the spray port 201 of the spray gun 2 can spray cleaning liquid to perform cleaning work.

[0058] After the spray gun 2 is used, the driving piece 501 is controlled to move towards the direction of driving the spray gun 2 to retract, and the second transmission piece 502 moves the first transmission piece 4 by magnetic force during the movement of the driving piece 501, so that the first transmission piece 4 drives the spray gun 2 to retract into the containing cavity 101. The cover body 3 covers the entrance 102, and then the steam generator 6 introduces steam into the containing cavity 101 through the air inlet 103, so as to sterilize the spray gun 2. The air outlet 104 can discharge the steam to maintain the pressure balance between the inside and outside of the containing cavity 101.

[0059] In this way, the second transmission member 502 on the driving member 501 and the first transmission member 4 on the spray gun 2 are attracted by magnetic force, so that the driving member 501 can drive the first transmission member 4 to move through the second transmission member 502, and then the first transmission member 4 drives the spray gun 2 to move, so that the spray gun 2 can be extended or retracted into the accommodating cavity 101 of the support 1, and the spray gun 2 can be driven to extend or retract by the driving member 501 without contact.

[0060] As described above, the driving member 501 and the spray gun 2 are driven by magnetic force between the first transmission member 4 and the second transmission member 502 without contact, so that the driving member 501 does not need to be arranged in the accommodating cavity 101, thereby solving the problem that the motor is arranged in the inside of the shell and is prone to aging or rust in the related art.

[0061] In addition, the driving member 501 is arranged outside the accommodating cavity 101, and the support 1 does not need to be provided with a through hole to avoid the first transmission member 4 or the second transmission member 502, thereby solving the problem that the motor is arranged outside the shell and is prone to steam leakage in the related art.

[0062] Reference Figure 5 As shown in some embodiments of the utility model, the driving member 501 is arranged as a driving wheel capable of reciprocating rotation, and the rotation axis of the driving wheel is out of plane with the slidable direction of the spray gun 2, for example, the rotation axis of the driving wheel is perpendicular to the slidable direction of the spray gun 2.

[0063] The first transmission member 4 comprises a plurality of first magnets 401 arranged on the spray gun 2 along the slidable direction of the spray gun 2. The second transmission member 502 comprises a plurality of second magnets 5021 arranged on the driving wheel along the circumferential direction of the driving wheel.

[0064] In this embodiment, when the spray gun 2 is needed to be used for cleaning, the driving member 501 is controlled to rotate in the direction of driving the spray gun 2 to extend, that is, the included angle between the linear velocity of the closest point of the driving wheel to the support 1 and the extending direction of the spray gun 2 is zero or acute. During the rotation of the second magnet 5021 with the driving member 501, the first magnet 401 is moved by magnetic force to drive the spray gun 2 to slide out of the accommodating cavity 101. With the rotation of the driving member 501, the second magnet 5021 on the driving member 501 successively attracts the first magnet 401 on the spray gun 2, so that the spray gun 2 gradually extends out of the accommodating cavity 101.

[0065] After the use of the spray gun 2 is finished, the control driving member 501 is rotated to the direction of driving the spray gun 2 to retract, that is, the included angle between the linear velocity of the driving wheel farthest from the support 1 and the retracting direction of the spray gun 2 is zero or acute. During the rotation of the control driving member 501, the second magnet 5021 moves the first magnet 401 by magnetic force, so that the first magnet 401 drives the spray gun 2 to slide into the containing cavity 101. With the rotation of the control driving member 501, the second magnet 5021 on the control driving member 501 successively attracts the first magnet 401 on the spray gun 2, and gradually makes the spray gun 2 extend out of the containing cavity 101.

[0066] In this way, the spray gun 2 can be driven to extend or retract by the rotation of the control driving member 501 in place, the space occupied by the control driving member 501 is small, so that the occupied space of the spray gun assembly can be improved, and the structure of the spray gun assembly is more compact.

[0067] Optionally, the driving wheel is rotatably connected with the support 1. For example, a mounting bracket is arranged on the support 1, and the driving wheel is rotatably arranged on the mounting bracket.

[0068] In this embodiment, the driving wheel is integrated with the support 1, so that the design of the spray gun assembly is more compact and integrated, thereby facilitating the reduction of the overall size of the equipment, and simplifying the assembly process and facilitating maintenance and repair.

[0069] Optionally, the spray gun assembly further comprises a motor, an output shaft of the motor is in transmission connection with the control driving member 501, and the motor is used for driving the control driving member 501 to rotate. In this embodiment, the control driving member 501 can be driven to rotate by the motor, so that the automation level of the spray gun assembly is improved. Optionally, the motor is arranged on the support 1. Of course, the motor is not limited to being arranged on the support 1, for example, the motor can also be fixed on other structural members.

[0070] In some embodiments of the utility model, in at least part of the two first magnets 401 adjacent to each other, the south pole of one faces the spray gun 2, and the south pole of the other faces away from the spray gun 2. For example, in all the first magnets 401 on the spray gun 2, in any two first magnets 401 adjacent to each other, the south pole of one faces the spray gun 2, and the south pole of the other faces away from the spray gun 2.

[0071] In at least part of the two second magnets 5021 adjacent to each other, the south pole of one faces the driving wheel, and the south pole of the other faces away from the driving wheel. For example, in all the second magnets 5021 on the control driving member 501, in any two second magnets 5021 adjacent to each other, the south pole of one faces the control driving member 501, and the south pole of the other faces away from the control driving member 501.

[0072] In the embodiment, as the driving member 501 rotates, the second magnet 5021 with a south pole facing outward on the driving member 501 gradually approaches the first magnet 401 with a north pole facing outward on the spray gun 2 and is attracted to each other, the second magnet 5021 drives the first magnet 401 to move, until the distance between the two is large and the attraction is removed.

[0073] As the driving member 501 continues to rotate, the second magnet 5021 with a north pole facing outward on the driving member 501 gradually approaches the first magnet 401 with a south pole facing outward on the spray gun 2 and is attracted to each other, the second magnet 5021 drives the first magnet 401 to move, until the distance between the two is large and the attraction is removed.

[0074] In this way, by arranging the south poles of the first magnets 401 on the spray gun 2 to alternate and arranging the south poles of the second magnets 5021 on the driving member 501 to alternate, when the second magnet 5021 on the driving member 501 is attracted to the corresponding first magnet 401 on the spray gun 2, the second magnet 5021 adjacent to the second magnet 5021 will not be attracted to the first magnet 401, so that the driving member 501 can more stably drive the spray gun 2 to slide.

[0075] Of course, the driving member 501 is not limited to being arranged as a driving wheel, for example, in other embodiments not shown provided by the utility model, the driving member 501 is arranged as a driving block that can reciprocatingly slide, and the slidable direction of the driving block is parallel to the slidable direction of the spray gun 2.

[0076] Correspondingly, the first transmission member 4 and the second transmission member 502 are both arranged as magnets, or one of the first transmission member 4 and the second transmission member 502 is arranged as a magnet and the other is arranged as an iron block. The number of the first transmission member 4 or the second transmission member 502 can be one or multiple.

[0077] In the embodiment, when it is needed to use the spray gun 2 for cleaning, the driving member 501 is controlled to slide in the direction of driving the spray gun 2 to extend out, in the process of the second magnet 5021 sliding with the driving member 501, the first magnet 401 is moved by magnetic force, so that the first magnet 401 drives the spray gun 2 to slide out of the containing cavity 101.

[0078] After the use of the spray gun 2 is completed, the driving member 501 is controlled to slide in the direction of driving the spray gun 2 to retract. In the process of the second magnet 5021 sliding with the driving member 501, the first magnet 401 is moved by magnetic force, so that the first magnet 401 drives the spray gun 2 to slide into the containing cavity 101.

[0079] In this way, by sliding the driving member 501, the spray gun 2 can be driven to extend out or retract.

[0080] Optionally, the driving wheel is in sliding connection with the support 1. For example, a guide rail is arranged on the support 1, and the driving wheel is arranged on the guide rail in a slidable manner.

[0081] In the embodiment, the driving member 501 is integrated with the support 1, which can make the design of the spray gun assembly more compact and integrated, thereby facilitating the reduction of the overall size of the equipment, and simplifying the assembly process and facilitating maintenance and repair.

[0082] Optionally, the spray gun assembly further comprises a reciprocating driving device. The reciprocating driving device is in transmission connection with the driving member 501 and is used for driving the driving member 501 to slide reciprocally. In the embodiment, the driving member 501 can be driven to rotate by the reciprocating driving device, thereby improving the automation level of the spray gun assembly.

[0083] Optionally, the reciprocating driving device is mounted on the support 1. Of course, the reciprocating driving device is not limited to being arranged on the support 1, for example, the reciprocating driving device can also be fixed on other structural members. Optionally, the reciprocating driving device is arranged as an electric cylinder or a pneumatic cylinder.

[0084] In some embodiments provided by the utility model, at least one of the first transmission member 4 and the second transmission member 502 has a spacing with the support 1, so as to reduce the friction force between the transmission member and the support 1.

[0085] In some embodiments provided by the utility model, along the slidable direction of the spray gun 2, the air inlet 103 and the air outlet 104 are arranged at two ends of the support 1 respectively, and in the state that the spray gun 2 is retracted into the accommodating cavity 101, one end of the spray gun 2 provided with the spray port 201 is close to the air inlet 103.

[0086] Since the part of the spray gun 2 provided with the spray port 201 is more likely to be contaminated, in the embodiment, the part of the spray gun 2 provided with the spray port 201 is close to the air inlet 103, so that the steam entering from the air inlet 103 can directly act on the part of the spray gun 2 provided with the spray port 201, thereby improving the sterilization effect on the spray gun 2.

[0087] In addition, the distribution of the air inlet 103 and the air outlet 104 at two ends of the support 1 can prolong the running path and running time of the steam in the support 1, thereby increasing the action area and contact time of the steam and the spray gun 2, and thereby improving the sterilization effect.

[0088] Reference Figure 6 As shown in the figure, in some embodiments provided by the utility model, the accommodating cavity 101 is provided with a guide structure 105, the guide structure 105 is arranged on the side of the spray gun 2 away from the driving member 501 and is connected with the support 1. The extension direction of the guide structure 105 is consistent with the slidable direction of the spray gun 2. The spray gun 2 is provided with a sliding structure 202 in sliding connection with the guide structure 105.
