Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to an anti-leakage installation structure and a device having the anti-leakage installation structure. Background Art

[0002] The existing cooling and heating tower fan is designed with two cooling and heating air ducts, which are equipped with two air inlets and two air outlets respectively. Since the warm air outlet is equipped with a non-detachable PTC heating element, a detachable warm air filter is usually designed at the warm air inlet for healthy air blowing. In the existing cooling and heating tower fan, the warm air filter is installed between the rear shell and the cold air grille. During installation, the warm air filter needs to be installed on the rear shell first, and then the cold air grille is installed. However, if the user forgets to install the warm air filter, the cold air grille can still be installed normally, which will cause the filter to be missed, affecting the healthy air blowing. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that some parts are easily missed during installation, thereby providing an anti-leaking structure in which parts are not easily missed during installation and a device with the anti-leaking structure.

[0004] The present invention provides a leakage-proof packaging structure, comprising:

[0007] A locking structure is provided in the mounting base and has a locking state for locking the ejection state of the ejection block and an unlocking state for releasing the locking of the ejection state of the ejection block;

[0008] The first component includes a first body and an unlocking structure arranged on the first body. When the first component is installed on the installation base, the unlocking structure drives the locking structure to switch from the locked state to the unlocked state through the opening.

[0009] The mounting base is provided with a first accommodating cavity communicated with the communicating port, and a second accommodating cavity communicated with the opening; the ejection structure is arranged in the first accommodating cavity, and the locking structure is arranged in the second accommodating cavity; the first accommodating cavity is communicated with the second accommodating cavity.

[0010] The locking structure comprises:

[0011] a locking body, which is disposed in the second accommodating cavity and moves in a direction away from the top block under the push of the unlocking structure when the first component is mounted on the mounting base;

[0012] A locking cavity, provided on one of the top block and the locking body;

[0013] A locking block, disposed on the other of the top block and the locking body;

[0014] The first biasing member is arranged in the second accommodating cavity, and one end of the first biasing member abuts against the cavity wall of the second accommodating cavity, and the other end abuts against the end of the locking body away from the top block, and applies a biasing force to the locking body to insert the locking block into the locking cavity.

[0015] The locking body comprises:

[0016] A pushing portion, one end of which is against the first biasing member and the other end of which is provided with the locking block or the locking cavity;

[0017] An extension portion extends from the push portion toward the opening and is adapted to contact the unlocking structure when the first component is mounted on the mounting base.

[0018] The movement direction of the locking body and the movement direction of the top block are perpendicular to each other.

[0019] The minimum length of the second accommodating cavity in the moving direction of the top block is equal to the maximum length of the locking body in the moving direction of the top block.

[0020] The minimum length of the first accommodating cavity in the moving direction of the locking body is equal to the maximum length of the top block in the moving direction of the locking body.

[0021] The locking cavity is a locking hole.

[0022] The ejection structure also includes a second biasing member, one end of which abuts against the cavity wall of the first accommodating cavity, and the other end of which abuts against an end of the top shell away from the connecting port, and applies a biasing force to the top block to make the top block extend into the installation space through the connecting port.

[0023] The present invention further provides a device with an anti-leakage structure, comprising the anti-leakage structure described above, and a second component installed in the installation space.

[0024] The device with the anti-leakage structure is a cooling and heating tower fan, the first component is a warm air filter of the cooling and heating tower fan, and the second component is a cold air grille of the cooling and heating tower fan.

[0025] The technical solution of the present invention has the following effects:

[0026] 1. The anti-leakage installation structure provided by the present invention comprises: an installation base, which is provided with an installation space, and a connecting port and an opening respectively connected with the installation space; an ejection structure, which comprises an ejection block arranged in the installation base, and the ejection block has an ejection state extending into the installation space through the connecting port, and a yielding state retracted into the installation base; a locking structure, which is arranged in the installation base and has a locking state for locking the ejection state of the ejection block, and an unlocking state for releasing the lock of the ejection state of the ejection block; a first component, which comprises a first body and an unlocking structure arranged on the first body, and when the first component is installed on the installation base, the unlocking structure drives the locking structure to switch from the locked state to the unlocked state through the opening. Through the ejection structure and the locking structure, during the assembly process, only when the first component is installed, the unlocking structure on the first component switches the locking structure from the locked state to the unlocked state, and the ejector block can be retracted into the installation base, and then other structures can be installed in the installation space; if the first component is not installed, the locking structure will always be in the locked state, so that the ejector block is maintained in the ejection state extending into the installation space, and then other structures cannot be installed in the installation space, which can remind the user to install the first component and effectively prevent the first component from being missed.

[0027] 2. The anti-leakage structure provided by the present invention comprises: a locking body, which is arranged in the second accommodating cavity and moves in a direction away from the top block under the push of the unlocking structure when the first component is installed on the installation base; a locking cavity, which is arranged on one of the top block and the locking body; a locking block, which is arranged on the other of the top block and the locking body; a first biasing member, which is arranged in the second accommodating cavity, and one end of which is against the cavity wall of the second accommodating cavity, and the other end of which is against the end of the locking body away from the top block, and applies a biasing force to the locking body to insert the locking block into the locking cavity. The locking structure of this structural form can be switched to the unlocking state only by the push of the unlocking structure. If the unlocking structure is separated from the locking body, the locking body will automatically return to the locking state under the biasing force of the first biasing member, so as to prevent the first component from being missed during the next assembly, and has the advantages of simple structure and easy implementation.

[0028] 3. In the anti-leakage structure provided by the present invention, the minimum length of the second accommodating cavity in the direction of movement of the top block is equal to the maximum length of the locking body in the direction of movement of the top block. In this way, the locking body can be limited by the second accommodating cavity to prevent the movement of the locking body from being offset or shaking during the movement, making the movement of the locking body more stable.

[0029] 4. In the anti-leakage structure provided by the present invention, the minimum length of the first accommodating cavity in the direction of movement of the locking body is equal to the maximum length of the top block in the direction of movement of the locking body. In this way, the top block can be limited by the first accommodating cavity to prevent the top block from deviating or shaking during movement, making the movement of the top block more stable.

DETAILED DESCRIPTION

[0044] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] like Figure 1-Figure 11 As shown, this embodiment provides an anti-leakage installation structure, including a mounting base 1, an ejection structure, a locking structure and a first component.

[0047] The mounting base 1 is provided with a mounting space 11 , and a communication port 12 and an opening 13 respectively communicating with the mounting space 11 .

[0048] The ejection structure includes an ejection block 21 disposed in the mounting base 1 . The ejection block 21 has an ejection state in which it is extended into the mounting space 11 through the communication opening 12 , and a yielding state in which it is retracted into the mounting base 1 .

[0049] The locking structure is provided in the mounting base 1 , and has a locking state for locking the ejected state of the ejector block 21 , and an unlocking state for releasing the locking of the ejected state of the ejector block 21 .

[0050] The first component includes a first body 31 and an unlocking structure 32 disposed on the first body 31 . When the first component is mounted on the mounting base 1 , the unlocking structure 32 drives the locking structure to switch from a locked state to an unlocked state through the opening 13 .

[0051] Through the ejection structure and the locking structure, during the assembly process, only when the first component is installed, the unlocking structure 32 on the first component switches the locking structure from the locked state to the unlocked state, and the ejector block 21 can be retracted into the installation base 1, and then other structures can be installed in the installation space 11; if the first component is not installed, the locking structure will always be in the locked state, so that the ejector block 21 is maintained in the ejection state extending into the installation space 11, and then other structures cannot be installed in the installation space 11, which can remind the user to install the first component and effectively prevent the first component from being missed.

[0052] In this embodiment, the mounting base 1 is provided with a first accommodating cavity 14 connected to the communicating port 12, and a second accommodating cavity 15 connected to the opening 13; the ejection structure is provided in the first accommodating cavity 14, and the locking structure is provided in the second accommodating cavity 15; the first accommodating cavity 14 is connected to the second accommodating cavity 15.

[0053] The specific structural form of the locking structure is not limited. In this embodiment, the locking structure includes a locking body 41 , a locking cavity, a locking block 43 and a first biasing member 44 .

[0054] The locking body 41 is disposed in the second accommodating cavity 15 , and moves in a direction away from the top block 21 under the push of the unlocking structure 32 when the first component is mounted on the mounting base 1 .

[0055] The locking cavity is disposed on the top block 21 , and the locking block 43 is disposed on the locking body 41 .

[0056] The first biasing member 44 is disposed in the second accommodating cavity 15, and one end thereof abuts against the cavity wall of the second accommodating cavity 15, and the other end abuts against the end of the locking body 41 away from the top block 21, and applies a biasing force to the locking body 41 to insert the locking block 43 into the locking cavity.

[0057] The locking structure of this structural form can be switched to the unlocked state simply by the push of the unlocking structure 32. If the unlocking structure 32 is separated from the locking body 41, the locking body 41 will automatically return to the locked state under the biasing force of the first biasing member 44, preventing the first component from being missed during the next assembly. It also has the advantages of simple structure and easy implementation.

[0058] As a convertible implementation, the locking cavity may be disposed on the locking body 41 , and the locking block 43 may be disposed on the top block 21 .

[0059] The specific structural form of the first biasing member 44 is not limited. In this embodiment, the first biasing member 44 is a spring. As a convertible implementation, the spring can also be replaced by an elastic body such as a rubber block.

[0060] The locking body 41 may have various specific structural forms. In this embodiment, the locking body 41 includes a pushing portion 411 and an extending portion 412 .

[0061] One end of the pushing portion 411 abuts against the first biasing member 44 , and the other end is provided with a locking block 43 .

[0062] The extending portion 412 extends from the pushing portion 411 toward the opening 13 and is adapted to contact the unlocking structure 32 when the first component is mounted on the mounting base 1 .

[0063] In this embodiment, the movement direction of the locking body 41 and the movement direction of the top block 21 are perpendicular to each other.

[0064] There can be many specific size relationships between the second accommodating cavity 15 and the locking body 41. In this embodiment, the minimum length of the second accommodating cavity 15 in the direction of movement of the top block 21 is equal to the maximum length of the locking body 41 in the direction of movement of the top block 21. In this way, the locking body 41 can be limited by the second accommodating cavity 15 to prevent the movement of the locking body 41 from being offset or shaking during the movement, so that the movement of the locking body 41 is smoother. As a convertible embodiment, the minimum length of the second accommodating cavity 15 in the direction of movement of the top block 21 can also be greater than the maximum length of the locking body 41 in the direction of movement of the top block 21.

[0065] There can be many specific size relationships between the first accommodating cavity 14 and the top shell. In this embodiment, the minimum length of the first accommodating cavity 14 in the direction of movement of the locking body 41 is equal to the maximum length of the top block 21 in the direction of movement of the locking body 41. In this way, the top block 21 can be limited by the first accommodating cavity 14 to prevent the top block 21 from deflecting or shaking during movement, making the movement of the top block 21 more stable. As a convertible embodiment, the minimum length of the first accommodating cavity 14 in the direction of movement of the locking body 41 can also be greater than the maximum length of the top block 21 in the direction of movement of the locking body 41.

[0066] The specific structural form of the locking cavity is not limited, and the locking cavity in this embodiment is a locking hole 42. As a convertible implementation, the locking hole 42 can also be replaced by a locking groove.

[0067] In this embodiment, the ejection structure also includes a second biasing member 22, one end of which abuts against the cavity wall of the first accommodating cavity 14, and the other end abuts against the end of the top shell away from the connecting port 12, and applies a biasing force to the top block 21 so that the top block 21 extends through the connecting port 12 to the installation space 11.

[0068] As a convertible embodiment, the ejection structure may not include the second biasing member 22, but a projection is formed in the locking hole 42, and a first inclined surface is provided on the side of the projection facing the locking block 43, and a second inclined surface matching the first inclined surface is provided on the side of the locking block 43 facing the projection, so that when the first component is not installed, the locking block 43 is inserted into the locking hole 42 under the action of the first biasing member 44, and in this process, the second inclined surface pushes against the first inclined surface, so that the ejection block 21 extends into the installation space 11, and after the first component is installed, the unlocking structure 32 of the first component drives the locking body 41 to move away from the ejection block 21, and the locking block 43 is disengaged from the locking hole 42, and the second inclined surface is separated from the first inclined surface, and the locking structure releases the locking of the ejection block 21 in the ejection state, and when other structures are installed in the installation space 11, the other structures installed in the installation space 11 will push the ejection block 21 back into the installation base 1. This type of inclined surface matching structure can also achieve leak-proof installation of the first component.

[0069] The specific structural form of the second biasing member 22 is not limited. In this embodiment, the second biasing member 22 is a spring. As a convertible implementation, the spring can also be replaced by an elastic body such as a rubber block.

[0070] Furthermore, in order to make the abutment between the first biasing member 44 and the pushing portion 411 more stable, and to make the abutment between the second biasing member 22 and the top block 21 more stable, in the present embodiment, a first guide column 51 is provided at one end where the pushing portion 411 abuts against the first biasing member 44, and the first biasing member 44 is sleeved outside the first guide column 51; a second guide column 52 is provided at one end where the top block 21 abuts against the second biasing member 22, and the second biasing member 22 is sleeved outside the second guide column 52.

[0071] This embodiment further provides a device with an anti-leakage structure, including the anti-leakage structure described above, and a second component 6 installed in the installation space 11 .

[0072] Specifically, the device with anti-leakage structure in this embodiment is a cooling and heating tower fan, the first component is the warm air filter of the cooling and heating tower fan, the second component 6 is the cold air grille of the cooling and heating tower fan, and the mounting base 1 is the rear shell of the cooling and heating tower fan.

[0073] When assembling the cooling and heating tower fan, only when the warm air filter is installed, the unlocking structure 32 on the warm air filter will switch the locking structure from the locked state to the unlocked state, and the top block 21 can be retracted into the installation base 1, and then the cold air grille can be installed in the installation space 11; if the warm air filter is not installed, the locking structure will always be in the locked state, so that the top block 21 will remain in the ejected state extending into the installation space 11, and then the cold air grille cannot be installed in the installation space 11, which can remind the user to install the warm air filter and effectively prevent the missing installation of the warm air filter.

[0074] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled 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 methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
