Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a pipe, a liquid storage device and a liquid supply device. Background Technology

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard surfaces while simultaneously drying wastewater and removing it from the site. It boasts advantages such as environmental friendliness, energy efficiency, and high performance. Handheld floor scrubbers are widely favored by consumers due to their ease of operation and flexibility. However, handheld floor scrubbers require returning to a base station after a period of use for refilling, wastewater recovery, or recharging.

[0003] The base station consists of the base station body and a water tank, with a water pump installed inside the base station body. When the handheld floor scrubber is refilled, the inlet on the water tank connects to the water pump in the base station body, so that the water in the water tank is drawn into the clean water tank of the handheld floor scrubber by the pump.

[0004] Obviously, after the water in the water tank is used up, it needs to be removed from the base station. Due to the siphon effect, after the water tank has replenished the handheld floor scrubber, there is usually some residual water in the pipe connecting it to the water pump. When the water tank is removed, the water can easily drip onto the ground, making the ground slippery and creating a safety hazard. Utility Model Content

[0005] The purpose of this invention is to provide a pipe, a liquid storage device, and a liquid supply equipment to solve the safety problem caused by water droplets falling to the ground due to liquid residue in the pipe.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a pipe, including a pipe body and an elastic membrane, wherein the pipe body is provided with an inlet, an outlet and a vent that are interconnected; the elastic membrane is movably disposed on the pipe body, and the elastic membrane includes a first state of closing the vent and a second state of opening the vent, wherein the elastic membrane switches from the second state to the first state when the inside of the pipe body is under negative pressure.

[0008] Optionally, the tube body has an installation groove, and the elastic membrane is confined within the installation groove.

[0009] Optionally, the mounting groove is formed at the top of the pipe body, and the mounting groove includes a large-diameter section and a small-diameter section arranged sequentially from bottom to top. The elastic membrane is placed in the large-diameter section, and the cross-sectional area of ​​the small-diameter section is smaller than the area of ​​the elastic membrane.

[0010] Optionally, the mounting groove is formed on the mounting portion protruding from the top of the pipe body, and the mounting portion is also provided with a clearance groove, which communicates with the mounting groove and extends radially along the mounting groove to the outer wall of the mounting portion.

[0011] Optionally, the mounting groove further includes a guide section disposed at the end of the smaller diameter section away from the larger diameter section, the guide section being configured as a tapered shape that gradually tapers from top to bottom.

[0012] Optionally, the elastic membrane includes a membrane body and a limiting portion, the limiting portion extending radially along the membrane body, the mounting groove including a main groove and a limiting groove, the limiting groove extending radially along the main groove, the limiting portion located within the limiting groove, the groove opening width of the limiting groove being smaller than the width of the limiting portion, and the membrane body located within the main groove.

[0013] Optionally, the bottom of the mounting groove is provided with a protrusion, and the protrusion has a connecting hole that connects to the vent. When the elastic membrane is in the first state, it is attached to the protrusion to block the connecting hole.

[0014] Optionally, the tube body includes a first section and a second section that are connected to each other.

[0034] refer to Figures 1-7 As shown, an embodiment of this utility model proposes a pipe for transferring liquid from a liquid storage device to another liquid storage device or a liquid application device. The pipe includes a pipe body 1 and an elastic membrane 2. The pipe body 1 has an inlet 15, an outlet 16 and a vent 17 that are interconnected. The elastic membrane 2 is movably disposed on the pipe body 1. The elastic membrane 2 includes a first state of closing the vent 17 and a second state of opening the vent 17. When the inside of the pipe body 1 is under negative pressure, the elastic membrane 2 undergoes elastic deformation to switch from the second state to the first state.

[0035] The aforementioned pipeline has a vent 17 on the pipe body 1, and an elastic membrane 2 is installed at the vent 17. Under normal circumstances, the elastic membrane 2 opens the vent 17. When liquid flows within the pipeline, the pipe body 1 is under negative pressure. At this time, the elastic membrane 2 undergoes elastic deformation, switching from the second state to the first state, preventing water from flowing out of the vent 17. After water supply is completed, the elastic membrane 2 returns from the first state to the second state, and air enters the pipe body 1 through the vent 17, eliminating the siphon effect in the pipe body 1. The water in the pipe body 1 flows out quickly through the outlet 16 or inlet 15 of the pipe body 1, reducing the possibility of water accumulating in the pipe body 1.

[0036] In one embodiment, the pipe body 1 is provided with an installation groove 13, the vent 17 is disposed at the bottom of the installation groove 13, and the elastic membrane 2 is confined within the installation groove.

[0037] Specifically, the tube body 1 includes a horizontally extending first section 11 and a vertically extending second section 12. The liquid inlet 15 is located at the end of the first section 11 away from the second section 12, the liquid outlet 16 is located at the end of the second section 12 away from the first section 11, and the vent 17 is located at the top of the first section 11.

[0038] More specifically, a mounting part is provided on the top wall of the end where the first segment 11 connects to the second segment 12, and a mounting groove 13 is opened on the mounting part, that is, the mounting groove 13 is opened on the top of the pipe body 1.

[0039] refer to Figure 2 and Figure 3 As shown, in one embodiment, the mounting groove 13 includes a large-diameter section 131 and a small-diameter section 132 arranged from bottom to top. The cross-sectional area of ​​the small-diameter section 132 is smaller than the area of ​​the elastic membrane 2, and the elastic membrane 2 is embedded in the large-diameter section 131. Specifically, the elastic membrane 2 is configured as a regular circle or polygon.

[0040] refer to Figure 1 As shown, to reduce the difficulty of assembling the elastic membrane 2 into the mounting groove 13, a clearance groove 14 is also provided on the mounting part. The clearance groove 14 connects to the mounting groove 13 and extends radially along the mounting groove 13 to the outer wall of the mounting part. When replacing the elastic membrane 2, the elastic membrane 2 is placed into the mounting groove 13 using a finger or auxiliary tool such as tweezers that passes through the clearance groove 14.

[0041] Specifically, the mounting groove 13 also includes a guide section 133, which is located at the end of the small diameter section 132 away from the large diameter section 131. The guide section 133 is set as a tapered shape that gradually narrows from top to bottom to reduce the difficulty of placing the elastic membrane 2 in the large diameter section 131.

[0042] refer to Figures 4-7As shown, in another embodiment, the elastic membrane 2 includes a membrane body 21 and a limiting part 22. The limiting part 22 is disposed on the membrane body 21 and extends radially along the membrane body 21. The mounting groove 13 is provided with a main groove 134 and a limiting groove 135 corresponding to the elastic membrane 2. The vent 17 is opened at the bottom of the main groove 134. One end of the limiting groove 135 is connected to the main groove 134, and the other end penetrates the outer wall of the mounting part. The width of the opening of the limiting groove 135 is smaller than the width of the limiting part 22, so that the limiting part 22 is limited within the limiting groove 135, thereby limiting the membrane body 21 within the main groove 134.

[0043] Specifically, limiting portions 22 are provided on both sides of the membrane body 21, and correspondingly, limiting grooves 135 are provided on both sides of the main body groove 134, so as to further improve the stability of the elastic membrane 2 in the mounting groove 13.

[0044] More specifically, in order to reduce the difficulty of assembling the limiting part 22 into the limiting groove 135, guide surfaces are provided on the groove sidewalls of the limiting groove 135 that are opposite to each other, and the two guide surfaces gradually approach each other from the groove opening direction of the limiting groove 135 to the groove bottom direction of the limiting groove 135.

[0045] refer to Figure 3 As shown, to increase the contact area between the elastic membrane 2 and the tube body 1 when the elastic membrane 2 is in the first state, thereby improving the reliability of the elastic membrane 2 sealing the vent 17, a protrusion 18 is provided around the vent 17 at the bottom of the mounting groove 13; the vent 17 is disposed through the protrusion 18. When the tube body 1 is under negative pressure, the elastic membrane 2 undergoes elastic deformation and can fit against both the top surface and the side surface of the protrusion 18, resulting in a better sealing effect on the vent 17. It can be understood that when the elastic membrane 2 is in the second state, there is a gap between the elastic membrane 2 and the protrusion 18. Exemplarily, the elastic membrane 2 is adhered to the side wall of the mounting groove 13.

[0046] refer to Figures 8-10 As shown, an embodiment of this utility model also proposes a liquid storage device, including a water tank 3 and the aforementioned pipe. The pipe is disposed inside the water tank 3 and connected to a liquid supply port 31 located at the bottom of the water tank 3. The liquid storage device supplies water to the outside via the pipe. Water inside the tank enters the pipe through the liquid inlet 15 and then flows through the pipe to the liquid supply port 31.

[0047] The embodiments of this utility model also propose a liquid supply device, which is not limited to a base station for floor scrubbers. The liquid supply device includes a water pump and the aforementioned liquid storage device. The liquid storage device is detachably mounted on the water pump, and the water pump provides a negative pressure environment for the pipeline.

[0048] Because the water in the pipe can quickly break the siphon effect when the pipe body 1 loses its suction force, the water in the pipe body 1 can quickly flow to another liquid storage device or liquid use device or return to the water tank 3. Therefore, when the water tank 3 needs to be replenished and the pipe is separated from the water pump, the probability of liquid dripping onto the ground is significantly reduced, thus reducing the possibility of the ground being slippery and improving the safety of use.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
