Description

Technical Field

[0001] This utility model relates to the technical field of fabric cleaning machines and their accessories, and in particular to a handle assembly and fabric cleaning equipment. Background Technology

[0002] The handle assembly of cleaning equipment typically includes a fluid flow channel and a control valve, with a button on the handle assembly for adjusting the valve's operating state. For scenarios requiring frequent switching of the control valve's operating state during operation, the button is usually designed to require continuous pressing by the user; pressing opens the fluid flow channel, while releasing closes it. While this design is reasonable and commonly used, the continuous pressing of the button places a significant burden on the user. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, a handle assembly and a fabric cleaning device are provided, which aim to free the user's hands and reduce the user's operating burden without the need for the user to continuously press the button, thereby overcoming at least one of the above-mentioned technical defects.

[0004] The specific technical solution is as follows: A handle assembly, comprising: The handle body has a brush head at one end, and the handle body has at least one liquid flow channel communicating with the brush head, and at least one of the liquid flow channels is equipped with a control valve for controlling the liquid flow interruption. The buttons are equal in number to the control valves and correspond one-to-one. The buttons are located in the handle body and at least partially protrude from the handle body. They have a first position state that causes the control valve to open the liquid flow channel and a second position state that causes the control valve to close the liquid flow channel. A locking component, mounted on the handle body and equal in number to the buttons, is used to allow the buttons to switch from a second position state to a first position state and to lock the buttons in the first position state, and to allow the buttons to switch from the first position state to the second position state after unlocking.

[0005] Preferably, one end of the button is hinged to the handle body, so that the other end of the button has a first rotation path for rotating about the hinge end. The locking member is movably disposed in the handle body and arranged opposite to the free end of the button. At least a portion of the locking member can extend into the first rotation path and cause the button to remain in the first position state.

[0006] Preferably, the lower end of the locking member is hinged to the handle body, so that the upper end of the locking member has a second rotation path about the hinge end, and the end of the button facing the locking member has at least one first latch, and the end of the locking member facing the button has a number of second latches that are opposite to the first latches. In the first position state, the first latches and the second latches abut against each other to prevent the button from resetting to the direction of the second position state.

[0007] Preferably, the first and second latches are both formed as inclined surfaces on their facing surfaces in the second position state, so as to allow the button to switch from the second position state to the first position state.

[0008] Preferably, the upper end of the locking member is provided with a push button, and the push button extends at least partially to the outer wall of the handle body.

[0009] Preferably, the locking member is provided with an elastic member at the end away from the button, so that the locking member is kept in the position where the first latch and the second latch are abutting, and can be rotated in the direction away from the button under the action of the push button to release the state of the first latch and the second latch abutting.

[0010] Preferably, the control valve includes a valve body having a valve cavity, a valve core movably disposed within the valve cavity, a valve stem extending out of the valve body and connected to the valve core, and a return spring disposed within the valve cavity and used to cause the valve core to reset. The end of the valve stem away from the valve core abuts against the button, and the return spring causes the button to reset from a first position state to a second position state.

[0011] Preferably, the handle body has two fluid channels, one of which is equipped with a control valve, and the number of buttons and locking components is one.

[0012] This utility model also provides a fabric cleaning device, including the handle assembly as described above, with two liquid flow channels serving as a clean water flow channel and a sewage flow channel respectively, and a control valve arranged in the clean water flow channel.

[0013] The beneficial effects of the above technical solution are as follows: The handle assembly includes a handle body, a brush head, a fluid flow channel, a control valve, a button, and a locking component. The working state of the control valve is adjusted by switching the position of the button, and the locking component can lock the button in the position where the fluid flow channel is open, eliminating the need for the user to continuously press the button, thus freeing the user's hands and reducing the user's operating burden. Moreover, the locking state can be released by the locking component, making it easy to operate and providing a better user experience. Attached Figure Description

[0019] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. And the following definitions are provided: Figure 3 The up-down direction shown on the paper is the up-down direction in this embodiment, and the left-to-right direction shown in the illustration is the front-to-back direction in this embodiment.

[0020] Example 1, See Figures 1 to 5 As shown in the figure, the handle assembly provided in this embodiment includes: The handle body 1 has a brush head 2 at one end. The handle body 1 has at least one liquid flow channel 4 connected to the brush head 2, and at least one of the liquid flow channels 4 is equipped with a control valve 5 for controlling the liquid flow. Button 3, which is equal in number to and corresponds one-to-one with control valve 5, is located in the handle body 1 and at least partially protrudes from the handle body 1, and has a first position state that causes control valve 5 to open the liquid flow channel 4, and a second position state that causes control valve 5 to close the liquid flow channel 4. The locking component 6 is installed on the handle body 1 and is equal in number to the button 3. It is used to allow the button 3 to switch from the second position state to the first position state and lock the button 3 in the first position state. After unlocking, it allows the button 3 to switch from the first position state to the second position state.

[0021] Based on the above technical solution, the handle assembly includes a handle body 1, a brush head 2, a liquid flow channel 4, a control valve 5, a button 3, and a locking member 6. The working state of the control valve 5 is adjusted by switching the position of the button 3, and the locking member 6 can lock the button 3 in the position that opens the liquid flow channel 4, eliminating the need for the user to continuously press the button 3, thus freeing the user's hand and reducing the user's operating burden. Moreover, the locking state can be released by the locking member 6, making it convenient to operate and providing a better user experience.

[0022] In a preferred embodiment, specifically as follows: Figure 2 , Figure 4 as well as Figure 5 As shown, one end of button 3 is hinged to handle body 1, so that the other end of button 3 has a first rotation path for rotating around the hinge end. Locking member 6 is movably disposed in handle body 1 and arranged opposite to the free end of button 3. At least a part of locking member 6 can extend into the first rotation path and cause button 3 to remain in the first position state.

[0023] In a further preferred embodiment, the lower end of the locking member 6 is hinged to the handle body 1, giving the upper end of the locking member 6 a second rotation path for rotation about the hinge end. The end of the button 3 facing the locking member 6 has at least one first latch 9, and the end of the locking member 6 facing the button 3 has the same number of second latches 10 as the first latches 9 and positioned opposite each other. In the first position state, the first latches 9 and the second latches 10 abut against each other vertically, preventing the button 3 from resetting to the second position state. Furthermore, the surfaces of the first latches 9 and the second latches 10 facing each other in the second position state are both configured as inclined surfaces to allow the button 3 to switch from the second position state to the first position state.

[0024] As a further preferred embodiment, the upper end of the locking member 6 is provided with a push button 8, and the push button 8 extends at least partially to the outer wall of the handle body 1, so as to facilitate manual control of the locking member 6 to rotate around the hinge end to unlock the button 3. Furthermore, an elastic member 7 (preferably a spring, but also a spring post) is provided at the end of the locking member 6 away from the button 3, so as to keep the locking member 6 in a position where the first latch 9 and the second latch 10 abut against each other, and can be rotated in a direction away from the button 3 under the action of the push button 8 to release the state in which the first latch 9 and the second latch 10 abut against each other.

[0025] It is worth noting that, firstly, the locking component 6 can also adopt an electrical structure of electromagnet + relay + button, with a metal part or magnet placed at the bottom of button 3 to achieve its locking purpose. Secondly, as a physical structure, the locking component 6 can also adopt a horizontal sliding button structure, which achieves the purpose of locking and unlocking button 3 by sliding back and forth. In addition, a slot and block structure can be set between button 3 and locking component 6, all of which can achieve the above purpose and are not limited to these.

[0026] In a preferred embodiment, combined with Figures 2 to 4 As shown, the control valve 5 includes a valve body 16 having a valve cavity, a valve core 15 movably disposed in the valve cavity, a valve stem 13 extending out of the valve body 16 and connected to the valve core 15, and a return spring 14 disposed in the valve cavity and used to reset the valve core 15. The end of the valve stem 13 away from the valve core 15 abuts against the button 3, and the return spring 14 causes the button 3 to reset from the first position state to the second position state.

[0027] In practical applications, pressing button 3 moves valve stem 13 and valve core 15, switching control valve 5 to the conducting state. Return spring 14 is compressed, and locking member 6 locks button 3, keeping it in the conducting state. When locking member 6 releases the button 3, the preload of return spring 14 resets valve core 15, valve stem 13, and button 3, corresponding to control valve 5 switching to the blocking state. Button 3 moves to the second position, and push button 8 resets to the position where the two latches abut against each other under the action of elastic member 7. Because of the inclined structure between them, push button 8 can move around the hinge end when button 3 is pressed again without affecting the button 3's switching to the first position. After completing the action, it resets under the action of elastic member 7, causing the two latches to abut against each other, thus preventing button 3 from resetting.

[0028] As a further preferred embodiment, the handle body 1 has two fluid flow channels 4, one of which is equipped with a control valve 5. The number of buttons 3 and locking components 6 is also one. However, as a reproducible structure, when the inner diameter of the handle body 1 is sufficiently large, theoretically more fluid flow channels 4, control valves 5, buttons 3, and locking components 6 can be provided. Therefore, their specific numbers can be determined based on requirements and are not limited to this.

[0029] Example 2, This embodiment provides a fabric cleaning device, including the handle assembly described in Embodiment 1, two liquid flow channels 4 which serve as a clean water flow channel 11 and a sewage flow channel 12 respectively, and a control valve 5 is arranged in the clean water flow channel 11.

[0030] Specifically, the clean water channel 11 is connected to the clean water tank of the fabric cleaning equipment via pipelines and a water pump, and the wastewater channel 12 is connected to the wastewater tank of the fabric cleaning equipment via pipelines and a suction device, which can meet the functional requirements of the fabric cleaning equipment.

[0031] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
