Description

Technical Field

[0001] The present invention relates to the technical field of sanitary products, and particularly to a pressing type paper outlet device. Background Art

[0002] In public places or household washrooms, in order to facilitate people to use toilet paper, a paper roll holder is usually installed beside the washbasin or in the toilet compartment. A roller is provided inside the paper roll holder, and a paper tube is sleeved on the roller. One end of the toilet paper on the paper tube extends out of the paper roll holder. When people use it, they pull the toilet paper extending outside the paper roll holder, and then they can pull the paper tube to rotate around the roller, and the toilet paper is continuously pulled out. After the pulled-out toilet paper reaches a certain length, the user tears it off for use.

[0003] This kind of paper roll holder has the following defects: (1) The paper roll holder continuously discharges paper, and there are often situations where too much toilet paper is pulled out. There are also some users who do not pay attention to saving paper and pull out much more toilet paper than actually needed, resulting in waste; (2) One end of the toilet paper needs to extend out of the paper roll holder and is exposed to the air in the washroom, which is easily polluted by the external environment and affects the hygiene of the paper towels.

[0004] Based on this, some paper outlet machines that use timing or metering devices to control the paper outlet length have emerged on the market. Typically, as described in the patent document (CN 209300959 U, September 12, 2018), it is equipped with a paper outlet device and a control circuit. The paper outlet device realizes paper outlet through an electrically driven main shaft, and the control circuit controls the paper outlet amount by collecting the number of rotations of the main shaft through a Hall element. Although the above-mentioned paper outlet machine can accurately control the paper outlet, it belongs to a small electrical appliance product, requires a standby power supply, has high manufacturing and operation and maintenance costs, and the electrical components are prone to aging and have poor reliability. Summary of the Invention

[0005] In order to realize low-cost and reliable quantitative paper outlet of the paper roll, the present invention provides a pressing type paper outlet device.

[0006] The technical solution adopted by the present invention is as follows: A pressing type paper outlet device includes two rolling clamping components that are arranged in pairs and closely adjacent to each other. The gap between the two rolling clamping components is used for clamping and leading out the paper roll. The device also includes a locking member and a reset member; the locking member has a first state of locking to prevent the rolling clamping component from rotating, a second state of releasing the rolling clamping component, and a third state of returning from the second state to the first state under the action of the reset member.

[0007] The beneficial effects of the present invention are as follows: when the locking member of the present invention locks the rolling clamping assembly, the rolling clamping assembly cannot rotate, the paper roll cannot be ejected, and the paper tearing action can be performed; when the locking member is released, the paper roll can be pulled out; and the locking member can be re-locked under the action of the reset member. That is, one operation of the locking member can complete the process of quantitative paper extraction, and quantitative paper ejection is achieved through a purely mechanical structure. Compared with electrical products, the cost is lower, it is less prone to failure, and the product reliability and stability are better.

[0008] Preferably, the locking member is a hinged rod, one end of which is a locking portion cooperating with the rolling clamping assembly, and the other end is a pressing portion, and the reset member is an elastic member acting on the hinged rod.

[0009] Preferably, the locking portion is a toothed structure, and in the first state, the linked gear on the rolling clamping assembly is meshed and locked with the locking portion.

[0010] Preferably, in the third state, the locking member drives the rolling clamping assembly to rotate via the one-way transmission assembly, and the rotation direction of the rolling clamping assembly is consistent with the paper output direction of the roll paper.

[0011] Preferably, the one-way transmission component is a one-way gear set structure or a ratchet structure.

[0012] Preferably, the one-way transmission assembly is a multi-stage reduction mechanism.

[0013] Preferably, the locking member is a hinged rod, one end of which is provided with a sector gear portion, and the sector gear portion is the power output section of the one-way transmission assembly.

[0014] Preferably, it also includes a shell assembly and a reel assembly, the reel assembly is used to place the roll paper, and the rolling clamping assembly, locking member, reset member, one-way transmission assembly and reel assembly are all installed in the shell assembly.

[0015] Preferably, the rolling clamping assembly comprises a roller, and an anti-slip sleeve with a plurality of elastic protrusions is provided on the outside of the roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described below in conjunction with embodiments and the accompanying drawings.

[0026] In the embodiment, as Figures 1 to 7 shown: A pressing type paper outlet device includes two rolling clamping assemblies 100 that are arranged in pairs and closely adjacent to each other. The gap between the two rolling clamping assemblies 100 is used to clamp and draw out the toilet paper 01, and further includes a locking member 200 and a reset member 300; the locking member 200 has a first state of locking to prevent the rolling clamping assembly 100 from rotating, a second state of releasing the rolling clamping assembly 100, and a third state of returning from the second state to the first state under the action of the reset member 300. When the locking member 200 of the present embodiment locks the rolling clamping assembly 100, the rolling clamping assembly 100 cannot rotate, the toilet paper 01 cannot be drawn out, and the tearing action can also be performed; when the locking member 200 is released, the toilet paper 01 can be pulled out; and the locking member 200 can be re-locked under the action of the reset member 300. That is, one operation action of the locking member 200 can complete the process of quantitatively taking paper, and quantitative paper outlet is realized through a pure mechanical structure, which has a lower cost compared with electrical products, is not prone to failure, and has better product reliability and stability.

[0027] In the embodiment, as Figures 3 to 5 , 7 shown: The locking member 200 is a hinged rod, one end of which is a locking portion 201 that cooperates with the rolling clamping assembly 100, and the other end is a pressing portion 202, and the reset member 300 is an elastic member acting on the hinged rod. The pressing portion 202 of the present embodiment extends out of the housing assembly 500 for easy pressing operation, and the reset member 300 is specifically a tension spring. Pressing the pressing portion 202 means Figure 5In the second state shown in B, after the pressing part 202 is released, the reset part 300 rebounds, that is Figure 5 the third state shown in C.

[0028] In the embodiment, as Figure 4 and 5 shown: The locking part 201 is a toothed structure. In the first state, the gear linked on the rolling clamping assembly 100 meshes with and locks the locking part 201. The locking part 201 in this embodiment is indirectly meshed with the rolling clamping assembly 100 for locking. The locking part 201 adopts a toothed structure, which is convenient for locking and disengaging with the gear structure and is not easy to get stuck.

[0029] In the embodiment, as Figures 2 to 5 shown: In the third state, the locking member 200 drives the rolling clamping assembly 100 to rotate through the one-way transmission assembly 400, and the rotation direction of the rolling clamping assembly 100 is the same as the paper outlet direction of the toilet paper 01. In the third state of this embodiment, the reset part 300 drives the rolling clamping assembly 100 to rotate in reverse as the power, without manually pulling the paper, so the operation is very convenient. Here, the meaning of the one-way transmission assembly 400 is that the downward pressure of the locking member 200 in the second state will not drive the rolling clamping assembly 100 to rotate, and this structure can prevent the toilet paper 01 from accumulating in the housing assembly 500.

[0030] In the embodiment, as Figure 3 and 4 shown: The one-way transmission assembly 400 is a one-way gear set structure or a ratchet structure. The one-way transmission assembly 400 can be realized in various ways. In this embodiment, the one-way gear set structure is adopted. At least one intermediate gear 401 in the one-way gear set has a floating shaft, which can float axially or radially. When the locking member 200 is pressed downward in the second state, the position of the intermediate gear 401 will move, so as to disengage from the meshing gears and cannot transmit power. When the locking member 200 is reset in the third state, the intermediate gear 401 will also be reset to restore the transmission function, so as to realize one-way transmission. In addition, this embodiment can also adopt a ratchet structure to realize one-way transmission. The above technical means are all mature technologies.

[0031] In the embodiment, as Figure 3 and 4 shown: The one-way transmission assembly 400 is a multi-stage reduction mechanism. The number of stages and transmission ratio of the one-way transmission assembly 400 in this embodiment can be designed according to actual needs. Generally, it is required that when the locking member 200 rotates a certain angle, the rolling clamping assembly 100 can rotate multiple weeks, so as to ensure that enough length of paper can be pulled out under one action of the rolling clamping assembly 100.

[0032] In the embodiment, as Figure 7As shown in the figure: The locking member 200 is a hinged rod, and a sector gear portion 203 is provided at one end thereof. The sector gear portion 203 is the power output section of the one-way transmission assembly 400. In the structure of this embodiment, the locking member 200 can directly drive the one-way transmission assembly 400 and the rolling clamping assembly 100 to rotate through the sector gear portion 203, with a compact structure and high movement reliability.

[0033] In the embodiment, as Figure 1 shown in the figure: It further includes a housing assembly 500 and a reel assembly 600. The reel assembly 600 is used for placing the toilet paper 01. The rolling clamping assembly 100, the locking member 200, the reset member 300, the one-way transmission assembly 400 and the reel assembly 600 are all installed in the housing assembly 500. The housing assembly 500 of this embodiment is a structure with an openable cover, which can protect the toilet paper 01 and the internal structure. The reel assembly 600 is a rotating shaft structure, and the toilet paper 01 can rotate around the reel assembly 600.

[0034] In the embodiment, as Figure 6 shown in the figure: The rolling clamping assembly 100 includes a roller 101, and an anti-slip sleeve 102 with a number of elastic protrusions is provided on the outside of the roller 101. This structure can ensure that the toilet paper 01 and the roller 101 can be evenly contacted in the axial direction, avoiding the situation of one side being tight and the other side being loose between the two rollers 101 due to the errors of the shape and axis of the roller 101, and ensuring smooth paper output. In addition, the roller 101 can be replaced by other forms of rotating parts, as long as it can maintain good contact with the toilet paper 01.

[0035] Obviously, the above embodiments of the present invention are only examples for explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
